    The pegmatite bodies of the Eastern Desert of Egypt are widely distributed especially along the Marsa-Alam-Idfu road. The Abu Dob area covers about 150km(2) of the Arabian Nubian shield at the central part of the Eastern Desert of Egypt. Most of the pegmatite is zoned; the zonation starts with milky quartz at the core followed by alkali feldspar at the margins. The feldspars vary in color from rose to milky and in composition from K-feldspar to Na-feldspar, sometimes interactions of both types are encountered. Thirteen feldspar samples were collected from different locations in the Abu Dob area for measuring the natural radioactivity of (238)U, (232)Th and (40)K using an HPGe detector. The variation in concentration of radionuclides for the area under investigation can be classified into regions of high, medium and low natural radioactivity. The average concentration in BqKg(-1) has been observed to be from 9.5 to 183675.7BqKg(-1) for (238)U, between 6.1 and 94,314.2BqKg(-1) for (232)Th and from 0 to 7894.6BqKg(-1) for (40)K. Radium equivalent activities (Ra(eq)), dose rate (D(R)) and external hazard (H(ex)) have also been determined. In the present work, the concentration of rare earth elements are measured for two feldspar samples using two techniques, Environmental Scanning Electron microscope XIL 30 ESEM, Philips, and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). The existence of rare earth elements in this area are very high and can be used in different important industries.

    Early Maastrichtian oil shales are hosted in the Duwi Formation of the Central Eastern Desert, Egypt. The examined member represents up to 20% of the total Duwi Formation. This interval is mainly composed of siliciclastic facies, phosphorites facies and carbonate facies. Oil shales microfacies is mainly composed of smectite, kaolinite, calcite, fluorapatite, quartz and pyrite. They are enriched in a number of major elements and trace metals in particular Ca, P, V, Ni, Cr, Sr, Zn, Mo, Nb, U and Y compared to the post-Archaean Australian shale (PAAS). Chondrite-normalized REEs patterns of oil shales for the studied area display light rare earth elements enrichment relatively to heavy rare earth elements with negative Ce/Ce* and Eu/Eu* anomalies. The most remarkable indicators for redox conditions are enrichments of V, Mo, Ni, Cr, U content and depletion of Mn content. Besides, V/V+Ni, V/Ni, U/Th, Ni/Co, authigentic uranium ratios with presence of framboidal shape of pyrite and its size are reflecting the deposition of these shales under marine anoxic to euxinic environmental conditions. Additionally, the ratio of Strontium (Sr) to Barium (Ba) Sr/Ba reflected highly saline water during deposition. Elemental ratios critical to paleoclimate and paleoweathering (Rb /Sr, Al2O3/TiO2), CIA values, binary diagram between (Al2O3+K2O+Na2O) and SiO2 and types of clay minerals dominated reflect warm to humid climate conditions prevailing during the accumulation of these organic-rich petroleum source rocks.

  4. Red Sea rift-related Quseir basalts, central Eastern Desert, Egypt: Petrogenesis and tectonic processes

    Mineral and whole-rock chemistry of Red Sea rift-related Tertiary basalts from south Quseir city, central Eastern Desert of Egypt is presented to investigate their petrogenesis and relationship to tectonic processes. The south Quseir basalts (SQB) are classified as high-Ti (TiO2 >2 wt.%) subalkaline transitional lava emplaced in an anorogenic tectonic setting. Their Mg# varies from 48 to 53 indicating the evolved nature of the SQB. Pearce element ratios suggest that the SQB magmas evolved via fractional crystallization of olivine + clinopyroxene ± plagioclase, but the absence of Eu anomalies argues against significant plagioclase fractionation. Clinopyroxene compositions provide evidence for polybaric fractionation of the parental mafic magmas. Estimated temperatures of crystallization are 1015 to 1207 °C for clinopyroxene and 1076 to 1155 °C for plagioclase. These values are interpreted to result from early stage crystallization of clinopyroxene followed by concurrent crystallization of clinopyroxene and plagioclase. The incompatible trace element signatures of the SQB (La/Ba = 0.08-0.10 and La/Nb = 0.89-1.04) are comparable to those of ocean island basalts (OIB) generated from an asthenospheric mantle source unaffected by subduction components. Modeling calculations indicate that the SQB primary magmas were derived from 4-5% partial melting of a garnet-bearing lherzolite mantle source. The NE Egyptian basaltic volcanism is spatially and temporally related to Red Sea rifting and to the local E-W striking faults, confirming a relationship to tectonic activity. Our results suggest that the extensional regime associated with Red Sea rifting controlled the generation of the Egyptian basalts, likely as a result of passive upwelling of asthenospheric mantle.

    Full Text Available The use of unicellular brown micro-algae has several advantages over conventional methods for removing rare earth elements (REEs from lithogenic materials. A comparative study is made to investigate the uptake and bioaccumulation of REEs from trachytic samples collected from El-Atshan mine area in the Central Eastern Desert of Egypt. The examined samples are characterized by their high REE content. Using Sargassum algae; it appears possible to reduce the abundance of the Light Rare Earths (LREEs; La, Ce, Nd, Pm, Sm and Eu that have a large atomic number. However, higher efficiency of the separation has been recorded for the heavy rare earths (HREEs which display a marked control of quantum failing (tetrad effect.

    Central Eastern Desert (CED), Egypt has long history of gold exploration and exploitation. In this study, we integrated Spectral Angular Mapper (SAM) technique and aeromagnetic data to map the gold mineralization associated within alteration zones in CED. The spectral reflectance curves of five main alteration minerals (Hematite, Illite, Kaolinite, Chlorite, and Quartz) were utilized as end members in the SAM supervised classification of ETM+ data. Each alteration mineral type was represented as a binary image that overlaid together to obtain single primary alteration map in CED. The possible pathways for the alteration migration was defined based on the subsurface and surface lineation features. For the subsurface lineation, Euler deconvolution filter was applied on the aeromagnetic data to locate the deep-seated faults. The surface lineation and shear zones were extracted from ETM+ data and used together with the subsurface lineation map to obtain a structural map. Layer intersection and fuzzy membership operation were applied for the entire datasets to identify the possible sites of alteration zones. Several GPS readings were taken from the field areas around the gold mine sites, and used as validation points for our primary results.

    This paper presents the results of a comprehensive petrographical and petrophysical investigation for the Late Cretaceous Nubia sandstone from Wadi Kareem in central Eastern Desert to measure their fluid flow properties and to investigate the effect of kaolinite on their petrophysical characteristics. From the petrographical analyses, scanning electron microscope 'SEM' and the X-ray diffraction 'XRD' analysis, it is shown that the studied sandstone samples are quite homogeneous in mineralogy and can be distinguished into four sedimentary microfacies: quartz arenite as a clean sandstone as well as three kaolinitic microfacies; namely they are kaolinitic quartz arenite, kaolinitic subarkose, and calcareous to kaolinitc quartz arenite. The main recognized diagenetic processes that prevailed during the post-depositional history of the Nubia sandstone are; compaction, cementation, alteration and dissolution of feldspar into kaolinite. The petrophysical potentiality of the studied sandstones was studied using the helium pycnometer, gas permeability and mercury injection confining pressure 'MICP' techniques. The investigated sandstones can be classified into three petrophysical facies with varying reservoir performances. The petrophysical behaviour of these facies is dependent mostly on their kaolinite content and its impact on porosity, permeability, irreducible water saturation, R35 (pore aperture corresponding to mercury saturation of 35% pore volume), R50 (median pore-throat radius), and MHR (the mean hydraulic radius). Therefore, the studied petrophysical facies are comparable to the distinguished petrographical facies.

    Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Phased Array L-band Synthetic Aperture Radar (PALSAR) images covering the Um Rus area in the Central Eastern Desert of Egypt were evaluated for mapping geologic structure, lithology, and gold-related alteration zones. The study area is covered by Pan-African basement rocks including gabbro and granodiorite intruded into a variable mixture of metavolcanics and metasediments. The first three principal component analyses (PCA1, PCA2, PCA3) in a Red-Green-Blue (RGB) of the visible through shortwave-infrared (VNIR + SWIR) ASTER bands enabled the discrimination between lithological units. The results show that ASTER band ratios ((2 + 4)/3, (5 + 7)/6, (7 + 9)/8) in RGB identifies the lithological units and discriminates the granodiorite very well from the adjacent rock units.The granodiorites are dissected by gold-bearing quartz veins surrounded by alteration zones. The microscopic examination of samples collected from the alteration zones shows sericitic and argillic alteration zones. The Spectral Angle Mapper (SAM) and Spectral Information Divergence (SID) supervised classification methods were applied using the reference spectra of the USGS spectral library. The results show that these classification methods are capable of mapping the alteration zones as indicated by field verification work. The PALSAR image was enhanced for fracture mapping using the second moment co-occurrence filter. Overlying extracted faults and alteration zone classification images show that the N30E and N-S fractures represent potential zones for gold exploration. It is concluded that the proposed methods can be used as a powerful tool for ore deposit exploration.

    Venomous scorpions have extreme importance in field of medicine and public health. This descriptive - analytic study was done to identify scorpion fauna, their ecological aspects as well as scorpionism for risk management and prevention of this health problem in Iran's central desert. Four urban and fifteen rural areas with various climates and topography locations were selected for monthly scorpion collection through a randomly cluster sampling in 2013. The clinical data was obtained from questionnaires provided in 2009-2014. Totally, 1481 scorpion sting cases were recorded. The majority were treated less than 6h after the sting. Statistical tests showed significant difference between season, scorpion's color, living place of patients and scorpionism cases. Plain areas had the most occurrence of scorpionism followed by foothills. Moreover, 311 scorpion samples belonged to 7 species of Buthidae were collected. Mesobuthus eupeus was the dominant species in both rural and urban areas. Most of the collected samples were from indoors, yards and around the houses. The most scorpion activity was recorded in the summer. The studied areas had rich scorpion fauna due to various climates and topography locations. Scorpion stings can be important and fatal in this area, particularly in the plain regions with semi-desert climate. An investigation for assessment of peoples' awareness on prevention methods of scorpionism and also the determination and the assessment of effective factors on reducing the elapsed time between scorpion stings and receiving medical care are here recommended.

    Problems in midwifery in many Central-Eastern European countries are very similar; it is possible to speak about the evolving Central-Eastern model of midwifery care. The educational models of this region have a relatively strong theoretical part; however, there is an insufficient practical dimension. Theoretical part of midwifery education in the universities is relatively autonomous and is slowly changing the professional identity of graduates.

    Orbital radar images of the central Namib Desert show clearly the extent of relict fluvial deposits associated with former courses of the Tsondab and Kuiseb rivers. South of the Kuiseb River, radar data show the existence of a drainage network developed in calcrete-cemented late Tertiary fluvial deposits. The sand-filled paleovalleys are imaged as radar-dark tones in contrast to the radar-bright interfluves where the calcreted gravels occur. The drainage network developed as a result of local runoff from indurated gravels and channeled surface and subsurface flow to the sites of the many interdune lacustrine deposits found in the area.

Using species distribution model (MAXENT), this study aimed to determine the potential distribution areas of Ammopiptanthus mongolicus and Ammopiptanthus nanus in the eastern Central Asian desert, and then to identify the determinant environmental variables contributing to the distri- bution. Results show that: (1) The produced potential distribution areas of A. mongolicus agree well with the observed ones, and species A. mongolicus are restricted distributed in the eastern and southern part of Alxa desert and the western Ordos of Inner Mongolia. The most suitable habitats are in the eastern edge of the Ulan Buh Desert and a small area of northern Helan Mountain. The distribution-influencing factors are mainly the extreme temperature and precipitation, for example, the most drought month

    2016-06-17

    IntroductionFrom May 2011 to August 2014, the U.S. Geological Survey (USGS) collected gravity data at more than 2,300 stations and physical property measurements on more than 640 rock samples from outcrops in the eastern Mojave Desert, California and Nevada. Gravity, magnetic, and physical-property data are used to study and locate regional crustal structures as an aid to understanding the geologic framework related to mineral resources of the eastern Mojave Desert.The eastern Mojave Desert is host to a world-class rare earth element carbonatite deposit located at Mountain Pass, California. Carbonatites are typically defined as magmatic rocks with high modal abundances of primary carbonate minerals >50 weight percent and elevated abundances of rare earth elements (REEs) (Nelson and others, 1988; Woolley and Kempe, 1989). The “Sulphide Queen” carbonatite ore deposit is a composite, tabular body made up of sills and dikes of REE-bearing sovites and beforsites that occurs just south of the Clark Mountain Range along a north-northwest trending fault-bounded block that extends along the northeast edge of the Mescal Range and northwestern extent of Ivanpah Mountains. This early to middle Proterozoic block is composed of a 1.7 Ga metamorphic complex of gneiss and schist that underwent widespread metamorphism and associated plutonism during the Ivanpah orogeny (Miller and others, 2007). Subsequently, these rocks were intruded by a series of granitoids, which included the 1.4 Ga (DeWitt and others, 1987) ultrapotassic alkaline suite of intrusions that are spatially and temporally associated with hundreds of dikes, outcrops, and a carbonatite ore body. The relative age sequence of this intrusive suite of alkaline rocks from oldest to youngest includes shonkinite, mesosyenite, syenite, quartz syenite, potassic granite, carbonatite, and late shonkinite dikes (Olson and others, 1954; Wooden and Miller, 1990; Haxel, 2005; Miller and others, 2007).

    Recent work suggests the following for the tectonic architecture of the central Georgia Eastern Piedmont. The Alleghenian-age, Modoc fault zone (MZ), first defined in S. Carolina, continues along strike (c. S60W) at least to the Ocmulgee R. (net length = 250 km), where it converges with the Ocmulgee (OF) and Goat Rock (GR) faults. Diverging to the S from the MZ is a sharp contact between migmatitic amphibolites and gneisses of the Sinclair Lake terrane (SLt) and lower grade metapelites and metapsammites of the Milledgeville terrane (Mt). Both are introduced by post-kinematic granites (likely Alleghanian). A previously undescribed, 10 km long ultramafite belt within SLt, the Shoulderbone zone (Sz), is concordantly foliated with respect to surrounding rocks--hence emplacement is considered as pre- or synkinematic. Numerous smaller ultramafite bodies exist within SLt, Metavolcanic rocks N of SLt and the intervening MZ are interpreted as Carolina slate belt (CSB) rocks extending farther SW than often depicted. Arc volcanism and plutonism, terrane amalgamation and subsequent Alleghanian plutonism, dextral shear zones (some with extensional components), and local tight folding contributed to the present architecture. Locally, accretionary wedge material may exist, but the authors find published views and maps describing the entire area as primarily an accretionary wedge thrust stack to be inappropriate.

    We evaluated nest site selection at two spatial scales (microsite, territory) and reproductive success of Western Burrowing Owls (Athene cunicularia hypugaea) at three spatial scales (microsite, territory, landscape) in the eastern Mojave Desert. We used binary logistic regression within an information-theoretic approach to assess factors influencing nest site choice and nesting success. Microsite-scale variables favored by owls included burrows excavated by desert tortoise (Gopherus agassizii), burrows with a large mound of excavated soil at the entrance, and a greater number of satellite burrows within 5 m of the nest burrow. At the territory scale, owls preferred patches with greater cover of creosote bush (Larrea tridentata) within 50 m of the nest burrow. An interaction between the presence or absence of a calcic soil horizon layer over the top of the burrow (microsite) and the number of burrows within 50 m (territory) influenced nest site choice. Nesting success was influenced by a greater number of burrows within 5 m of the nest burrow. Total cool season precipitation was a predictor of nesting success at the landscape scale. Conservation strategies can rely on management of habitat for favored and productive nesting sites for this declining species.

    A world-class, rare earth element carbonatite deposit is located near Mountain Pass, in the eastern Mojave Desert of California and is hosted by Proterozoic rocks that extend along the eastern margins of the Clark Mountain Range, Mescal Range, and Ivanpah Mountains in a north-northwest trending fault-bounded block. This Proterozoic block is generally composed of a complex of 1.7 - 1.6 Ga gneisses and schists that are intruded by ~1.4 Ga carbonatite and ultrapotassic mafic dikes. In the latter suite, common intrusive rock types include shonkinite, syenite, and alkali granites that are associated with carbonatite dikes. Regional geophysical data reveal that the carbonatite deposit itself occurs along the northeast edge of a prominent magnetic high with an amplitude of 200 nanoteslas, which appears to be related to the surrounding Proterozoic block. More than 340 gravity stations and 155 physical property samples were collected to augment existing geophysical data to determine the geophysical and geologic setting of the eastern Mojave Desert carbonatite terrane. Physical properties of representative rock types in the area show that 23 samples of carbonatite ore have an average saturated bulk density of 2,866 with a range of 2,440 to 3,192 kg/m3 and a magnetic susceptibility of 0.22 with a range of 0.03 to 0.61x 10-3 SI units, 17 samples of syenite have an average saturated bulk density of 2,670 with a range of 2,555 to 2,788 kg/m3 and a magnetic susceptibility of 3.50 with a range of 0.19 to 11.46 x 10-3 SI units, 19 samples of shonkinite dike have an average saturated bulk density of 2,800 with a range of 2,603 to 3,000 kg/m3 and a magnetic susceptibility of 0.71 with a range of 0.00 to 4.44 x 10-3 SI units, and 28 samples of Proterozoic gneiss have an average saturated bulk density of 2,734 with a range of 2,574 to 3,086 kg/m3 and a magnetic susceptibility of 1.23 with a range of 0.01 to 7.48 x 10-3 SI units. In general, carbonatites have distinctive gravity

    For the last 50 years, the economic and industrial development of the nations of Central and Eastern Europe has been achieved at the cost of environmental degradation. The health risks posed by this pollution to children and the steps necessary to ameliorate such risks are only beginning to be investigated. At a recent conference in Poland, sponsored in part by the National Institute of Environmental Health Sciences, participants from 11 countries in the region, together with scientists from Western Europe and the United States, met to share information regarding pediatric environmental health in Central and Eastern Europe, to consider methodologic issues in the design and conduct of such studies, and to discuss preventive strategies. This report summarizes the deliberations, outlines problem areas such as heavy metals and air pollution, delineates research and training needs to help Central and Eastern Europeans deal more effectively with such problems, and recommends specific future actions and collaborative efforts.

    It is believed that the Lut desert features, in elevation and volume, are unique (even in the world) in central Iran. These huge morphological features will be an excellent Sedimentary Archive in quaternary explaining the climate condition and distribution of desert surface features on the earth, meanwhile the attention less has gone on the Aeolian features in the area of interest because it is hard to access. This papers aims to present these unique features by remote sensing data. Remote sensing data including, Irs Aster, Srtm and Arial photograph data were used to measure the dune migration and other aspects of desert environment. Sand dune morphology encompasses almost all typical desert features including single, linear, pyramid, star sand and others. compressing remote sensing data between 1955 and 2000 approves the single Barkhan is being migrated at the rate of 22.65 M per year and accelerate at the last period between 2000 and 2008. A large part of scarce vegetation represents active and rapid migration creating huge morphological features. Linear dune elevation reaches more than 430 M and shows the highest elevation of dune activity on Earth. To evaluate surface temperature Aster 08 production were used. The surface temperature on the sand is probably the highest temperature received by solar energy around 84 Celsius degrees resulting High thermal cell in central Iran. This causes to create huge morphological features in central Iran reaching more than 400 m high due to repetition and reactivation under closed circumstance system.

    Remote sensing and radiometric survey techniques in the area between Qusier and Mersa Alam show variation of content of natural radioactivity in Wadi Wizr area, Eastern Desert of Egypt Gamma-ray, and laser fluorimetry were applied to measure the natural radioactivity content in representative content in representative samples from Wadi Wizr. The concentration of {sup 226}Ra ranged from 36 to 661 Bq kg{sup -1}, while the radioactivity ratio between {sup 226}Ra/{sup 214}Pb and {sup 214}Pb/{sup 214}Bi ranged from 0.7 to 1.4. The activity ratio {sup 238}U/{sup 226}Ra% was found to be in the range 6.4%-72.2%. A state of disequilibrium between the two radionuclides in the uranium series is clear. The trend of disequilibrium was obvious in all the investigated sites and correlating both radionuclides, {sup 238}U/{sup 226}Ra demonstrated the site variation influence. Samples were also analyzed by XRD to reveal their mineral composition.

    In this study, the root systems of desert plant species Reaumuria soongorica and Nitraria tangutorum in the central Hexi Corridor of Northwest China were excavated by shovel, and the characteristics of the plant root architecture were analyzed by using topology and fractal theory. The root topological indices of the two desert plants were small, and the root branching patterns were herringbone-like. The roots of the two desert plants had obvious fractal characteristics, with the fractal dimension of R. soongorica and N. tangutorum being (1.18 +/- 0.04) and (1.36 +/- 0.06), respectively. The root fractal dimension and fractal abundance were significantly positively correlated with the root average link length. The root average link lengths of the two plants were long, which enlarged the plants' effective nutrition space, and thus, made the plants adapt to the dry and infertile soil environment. The sums of the root cross-sectional areas before and after the root bifurcation of the two desert plants were equal, which verified the principle of Leonardo da Vinci. A total of 17 parameters of root architecture were analyzed by the principal component analysis. The parameters of root topological structure, numbers of root links, stepwise branching ratio, and root diameter could well present the root architecture characteristics of the two desert plants.

    Full Text Available The study brings an overview of selected transdisciplinary theoretical approaches to the study of urban movements and activism placed within the framework of civil society and social movements, focused on the region of Central and Eastern Europe, and seen from a social anthropological perspective. It attempts to challenge older academic writings that described civil society in Central and Eastern Europe as underdeveloped and weak, and presents research that points out a specific nature of activism in the countries of the region. It builds primarily on the concepts of civil society, social movements, urban movements and urban activism as presented by scholars both from “Western” and “Central and Eastern” European countries and demonstrates that after more than two decades since the fall of communism it is still important to take different historic, political, economic, social and cultural contexts into account when comparing urban movements and activism within Europe.

    Reconstructing the evolution of arid landscapes is challenged by the limited availability of appropriate environmental archives. A widespread surface feature of arid landscapes - stone pavement - traps eolian fines and can form an accretionary archive, growing with time and thereby recording essential information about the conditions under which it evolves. Based on a regional example in the eastern Mojave Desert, USA, seven stone pavement-covered soil-sediment sections on 560 and 270 ka old basalt flows are condensed to a correlation framework, comprising five distinct, successive sedimentological units. An OSL-based chronology enables correlation of this new sediment archive with other environmental archives from the region. Three of the stratigraphic units are of accretionary nature and the top of each unit is mantled by a new generation of stone pavement. These stratigraphic units were deposited between >32.3-20.4 ka, 20.4-16.5 ka and younger than 16.5 ka, appearing to be strongly coupled with the history of the nearby ancient Lake Mojave and enhancing our knowledge of the eolian activity in this area. End-member modelling analysis of sampled grain-size distributions allows identification of a local detritus component, four separate eolian components and two distinct clay enrichment components, contributing different quantities of sediment sources to the five stratigraphic units. These findings improve current concepts about the evolution of stone pavements and their role as conveyers of information about environmental conditions in arid landscapes. Stone pavement-covered accretionary sediment deposits are a new key archive that allows quantifying the relative importance of dust accretion, slope processes, soil formation and vegetation cover.

  2. Illegal Migration and Human Smuggling in Central and Eastern Europe

    Full Text Available The analytical and statistical services of border management organizations in Central and Eastern European countries have registered and accumulated a vast body of knowledge on the demographics and mechanisms of illegal migration over the last one-and-a-half decade. This paper attempts to tap this resource by summarising the results of a yearly survey among border guards of 17 countries. A set of quantitative indicators of illegal migration is developed, presented and interpreted, based on the answers of the border services to a series of quantitative and qualitative questions. This empirical material is used to evaluate the dynamics and pattern of illegal migration in Central and Eastern Europe on the one hand, and to examine the development of border management strategies on the other. The impacts of legal and institutional reforms are investigated in light of the temporal and spatial variations of border apprehension statistics. The interdependence of the two processes is reviewed from the point of view of national border management authorities, perhaps the most authoritative source of information on the issue. The results of the authors’ annual survey indicate that the progressive development of migration control mechanisms at national and international levels seems to have a significant impact on irregular migration flows as most indicators of illegal migration have significantly decreased after the turn of the century. At the same time, the geographical distribution of illegal migration flows in Central and Eastern European countries has become more complex over the years.

    During the late Pleistocene, emergent groundwater supported persistent and long-lived desert wetlands in many broad valleys and basins in the American Southwest. When active, these systems provided important food and water sources for local fauna, supported hydrophilic and phreatophytic vegetation, and acted as catchments for eolian and alluvial sediments. Desert wetlands are represented in the geologic record by groundwater discharge deposits, which are also called spring or wetland deposits. Groundwater discharge deposits contain information on the timing and magnitude of past changes in water-table levels and, thus, are a source of paleohydrologic and paleoclimatic information. Here, we present the results of an investigation of extensive groundwater discharge deposits in the central Mojave Desert at Valley Wells, California. We used geologic mapping and stratigraphic relations to identify two distinct wetland sequences at Valley Wells, which we dated using radiocarbon, luminescence, and uranium-series techniques. We also analyzed the sediments and microfauna (ostracodes and gastropods) to reconstruct the specific environments in which they formed. Our results suggest that the earliest episode of high water-table conditions at Valley Wells began ca. 60 ka (thousands of calendar yr B.P.), and culminated in peak discharge between ca. 40 and 35 ka. During this time, cold (4–12 °C) emergent groundwater supported extensive wetlands that likely were composed of a wet, sedge-rush-tussock meadow mixed with mesic riparian forest. After ca. 35 ka, the water table dropped below the ground surface but was still shallow enough to support dense stands of phreatophytes through the Last Glacial Maximum (LGM). The water table dropped further after the LGM, and xeric conditions prevailed until modest wetlands returned briefly during the Younger Dryas cold event (13.0–11.6 ka). We did not observe any evidence of wet conditions during the Holocene at Valley Wells. The timing

    Abu El-Ela, Fawzy F.

    1997-05-01

    The Wadi Dabr intrusive complex, west of Mersa-Alam, Eastern Desert, Egypt ranges in composition from gabbro to diorite, quartz diorite and tonalite. The gabbroic rocks include pyroxene-horn blend e gabbro, hornblende gabbro, quartz-hornblende gabbro, metagabbro and amphibolite. Mineral chemistry data for the gabbroic rocks indicate that the composition of clinopyroxenes ranges from diopside to augite and the corresponding magma is equivalent to a volcanic-arc basalt. Plagioclase cores range from An 75 to An 34 for the gabbroic varieties, except for the metagabbro which has An 11-18. The brown amphiboles are primary phases and classified as calcic amphiboles, which range from tschermakitic hornblende to magnesiohornblende. Green hornblende and actinolite are secondary phases. Hornblende barometry and hornblende-plagioclase themometry for the gabbroic rocks estimate crystallisation conditions of 2-5 kb and 885-716°C. The intrusive rocks cover an extensive silica range (47.86-72.54 wt%) and do not exhibit simple straight-line variation on Harker diagrams for many elements (e.g. TiO 2, Al 2O 3, FeO ∗, MgP, CaO, P 2O 5, Cr, Ni, V, Sr, Zr and Y). Most of these elements exhibit two geochemical trends suggesting two magma sources. The gabbroic rocks are relatively enriched in large ion lithophile elements (K, Rb, Sr and Ba) and depleted in high field strength elements (Nb, Zr, Ti and Y) which suggest subduction-related magma. Rare earth element (REE) data demonstrate that the gabbroic rocks have a slight enrichment of light REE [(La/Yb) N=2.67-3.91] and depletion of heavy REE ((Tb/Yb) N=1.42-1.47], which suggest the parent magma was of relatively primitive mantle source. The diorites and tonalites are clearly calc-alkaline and have negative anomalies of Nb, Zr, and Y which also suggest subduction-related magma. They are related to continental trondhjemites in terms of RbSr, KNaCa, and to volcanic-arc granites in terms of Rband NbY. The Wadi Dabr

  7. Diagenesis of the lower Eocene Thebes Formation, Gebel Rewagen area, Eastern Desert, Egypt

    Shaaban, Mohamad N.

    2004-03-01

    The diagenesis of lower Eocene shallow water carbonates with flint was studied in the Gebel Rewagen area, Eastern Desert, Egypt. The carbonates are mainly wackestones to packstones with benthic bioclasts embedded in a dark red luminescent micrite matrix. The studied succession displays a complex diagenetic history that involves syngenetic and late diagenetic processes. Silica, which exists either as persistent bands, nodules and/or silicified benthic bioclasts shows a distinctive pattern regarding its distribution, source, depositional environments and timing. Three lines of evidence support a syngenetic origin of the chert bands: (1) they alternate in a cyclic manner within the host carbonates and (2) they exhibit noticeable lateral persistence throughout the investigated area following the strata boundaries and (3) there is a lack of any carbonate dissolution in limestone adjacent to chert bands. The deposition of silica bands in association with shallow water carbonates is possibly related to eustatic sea-level changes, which were accompanied by episodic variations in silica and carbonate productivities. With a relative sea-level fall and the establishment of a lowstand period at the end of the early Eocene, a basinward shift of the groundwater zones is expected within the carbonate platform. During this period some late diagenetic processes took place, which involve: (1) the formation of siliceous and carbonate concretionary growths, (2) partial silicification of bioclasts, (3) neomorphic stabilization of the CaCO 3 bioclasts and (4) the formation of equant calcite cement. Siliceous and carbonate concretions are believed to have taken place within microenvironments created and controlled by sulphate-reducing bacteria and physico-chemical and kinetic factors near a marine-meteoric water mixing zone. This is inferred from the distribution of iron sulphides, the non-ferroan nature of all concretions and the depleted δ13C (-5.4‰ to -6.0‰ PDB) and δ18O (-5.8

    2001-01-01

    Full Text Available This article explores the impact of the activity of international solidarity and human rights organizations on the political involvement of the Roma in Central and Eastern Europe. It will conclude that the increase of an international advocacy network focussing on the plight of the Roma has offered new opportunities to domestic Romani organizations for pressuring governments to change state behaviour or to introduce new policy. In some cases, governments have even appointed Romani personalities from well-known advocacy organizations to advisory positions. However, the influence of a growing advocacy network has not been able yet to create a better democratically elected representation of the Roma in the central arenas of political decision-making on domestic level. Moreover, within domestic Romani movements there is growing discussion about the legitimacy and accountability of Romani advisors.

    2010-08-01

    Environmental analytics is one of the most important applications of ion chromatography. It includes determination of ions in water and wastewater as well as in gaseous and solid ones. Nowadays, ion chromatography has almost completely displaced the classical methods of ion determination in these areas. In spite of the fact that the ion chromatography has been officially present in the scientific world for 36 years, its role and popularity is highly diversified in various countries and regions of the world. In highly industrialized countries, it has been a reference method of water and wastewater analysis for years. In other parts of the world, it is not used and appreciated sufficiently despite its undeniable advantages. The following paper is a short overview of the most highly cited scientific and research institutions that conduct research in terms of environmental applications of ion chromatography in Eastern and Central Europe. Furthermore, the paper presents a list of a number of scientific papers referring to the discussed area, published in the years 1996-2009 in some of the most highly cited international scientific journals, and concerning publications of scientists from Eastern and Central Europe seen against the background of Europe and the world.

    2016-04-01

    Archaeological and cultural heritage of Egypt is world-known, but its geological heritage is yet to be revealed. Investigations in the central Western Desert of Egypt permitted finding a lot of unique features that can be assigned to this heritage. In the Bahariya Oasis, 10 geological heritage types are established, namely stratigraphical, paleontological, sedimentary, igneous, mineralogical, economical, paleogeographical, geomorphological, hydrological and hydrogeological, and pedological types. In the Farafra Oasis and vicinities, only geomorphological and hydrological and hydrogeological types are found. On the area between these oases, sedimentary, mineralogical, paleogeographical, and geomorphological features are established. Chalk and nummulitic limestones, invertebrate and dinosaur localities, paleoreefs and paleokarst, iron ore deposit, and peculiar landforms occur on the study territory. Taken together, these features constitute a highly diverse geological heritage that can be judged global (even if the rank of individual objects is often relatively low). This heritage is well suitable for the purpose of geotourism; for instance, thematic excursions explaining the geological evolution during the last 100 Ma are possible. Participants of such excursions can also see different facies. A geopark in the central Western Desert of Egypt would facilitate geoconservation and geotourism activities.

    2007-03-01

    Harm reduction (HR) interventions began in Central-Eastern Europe and Central Asia in the mid-1980s with the establishment of substitution treatment (ST) in Yugoslavia. In the mid-1990s, the first needle and syringe programmes (NSPs) opened in selected countries following the outbreaks of HIV among injecting drug users (IDUs). The number of NSPs continues to increase via a combination of international and state funding with large expansions made possible via the Global Fund to Fight AIDS, Tuberculosis and Malaria. While ST is still unaccepted in several countries, others have made some progress which is especially visible in South Eastern and Central Europe and the Baltic States. Development of regional networking including Central and Eastern European HR Network and a number of national networks helped to coordinate joint advocacy effort and in some cases sustain HR services. Activism of drug users and people living with HIV (PLWH) increased in the region in the last several years and helped to better link HR with the affected communities. Still a number of challenges remain important for the movement today such as repressive drug policies; stigma and discrimination of IDUs, PLWH, sex workers and inmates, including poor access to prevention and treatment; lack of important components of HR work such as naloxone distribution and hepatitis B vaccination, prevention in prisons; issues of quality control; sustaining services after finishing of major international projects; reaching of adequate coverage and others.

    Eastern Europe and Central Asia represent one of the few regions globally where there is a continued increase in the incidence of HIV infection. For example, in Eastern Europe the rate of diagnosed cases of HIV infection per 100 000 population has increased from 11.7 in 2004 to 22.5 in 2011. Initially propelled by injection drug use, heterosexual transmission has now become a major driver of new infections in the region. Nonetheless substance use remains an important factor, with its control limited by challenges in scaling up harm reduction efforts. While most countries have implemented opioid substitution therapy programs, their scale remains very limited. Similarly, coverage of needles syringe programs across the region is variable. Complicating the control of HIV has been the emergence of non-injection drugs and inadequate access to antiretroviral therapy. In addition, structural barriers and stigma toward HIV infected people may contribute to the high proportion of late presentations for HIV care. Finally in the wake of the HIV epidemic, high rates of hepatitis C infection and tuberculosis have been noted.

    Full Text Available The Taklimakan Desert in the Tarim Basin is the largest desert in Central Asia, and is regarded as one of the main dust sources to the Northern Hemisphere. Late Cenozoic sedimentary sequences with intercalated in-situ aeolian dune sands in this area preserve direct evidence for the Asian desertification. Herein, we report a high-resolution multi-proxy climatic record from the precise magnetostratigraphic dated Hongbaishan section in the central Taklimakan Desert. Our results show that a fundamental climate change, characterized by significant cooling, enhanced aridity, and intensified atmospheric circulation, occurred at 2.8 Ma. Good correlations between climate records in the dust sources and downwind areas suggest a broadly consistent climate evolution of northwestern China during the late Cenozoic, which is probably driven by the uplift of the Tibet Plateau and the Northern Hemisphere glaciation.

    Full Text Available In his article 'Multiculturalism and Minority Rights: West and East', Will Kymlicka argues, among others that a key condition for the success of legal and political reforms in the area of minority rights is a fundamental change in public attitudes towards and acceptance of the legitimacy and normality of nationalist mobilization by substate national groups. Following a brief overview of the complexity of ethnic relations in Central and Eastern Europe and the intricacy of minority-state relations, the author of this article contends that, contrary to Kymlicka, the region might even be better off if political spaces were constructed around other than ethnic identities. In line with Kymlicka, it is nevertheless conceded that there may be a need in several cases for lengthy transition periods in which ethnic identities are given institutional space ans security to play an important role in everyday politics.

    The European Union (EU) Member States in central and eastern Europe (CEE) witnessed a surge in outward foreign direct investment (OFDI) between 2000 and the start of the global financial crisis. This article investigates whether the European integration process altered the relative importance...... of host country location factors. In particular, we investigate to what extent knowledge-seeking is a relevant investment motive, which has been documented as a key determinant for OFDI from other emerging economies. We apply a discrete choice approach to model foreign location choice of firms from CEE...... countries (CEECs) within the EU 27 (1996-2010). We find that the EU integration process is related with increasing importance of market access and less emphasis on labour cost advantages. We find heterogeneity in the valuation of foreign knowledge-related assets. The location probability within the EU15...

  19. Microfacies analysis of foraminifera rich sedimentary rocks from the Desert Plateau, central Egypt.

    Microfacies analysis on some samples from the Thebes Group have been carried on by means of thin sections. The study area is included in the Libyan Desert Plateau (central Egypt) at following coordinates N27° 36'30.58" E29° 44'58.34", near the biggest dune of Egypt, the Ghard Abu Muharik. Because of the round shape of the rocks and the desert patina on the surface they could easily be classified as the so called "Melonstones", which are located more southwards and mainly composed by stromatolites. On the contrary, the investigated samples show a completely different fauna and therefore have been separated from the "Melonstones". Even if shape and size are very similar and the desert patina covers all surfaces the same way the differences are impressive. To investigate the samples, two thin-sections have been prepared and analyzed at the microscope. The observed fauna is composed by: agglutinated benthic foraminifera (e.g., Dictyoconus egypticus), complex larger miliolids (e.g., Pseudolacazina cf. danatae, Fabularia sp.), alveolinids (Alveolina vredenburgi), green algae (Dasycladaceae), echinoids and corals. Because of the presence of symbionts bearing larger benthic foraminifera, which need light to feed photosymbionts, the rock was formed in a shallow water environment. With the abundant rock-building benthic foraminifera and calcareous algae the limestone shows a tendency to the packstone/wackestone facies. Based on the presence of Alveolina vredenburgi, the age of the samples can be estimate as lowermost Eocene belonging to the shallow benthic zone 5 (sensu Serra-Kiel et al., 1998). According the obtained data on stratigraphy and palaeoecology, a partial palaeoenvironmental reconstruction is possible for the Libyan Desert Plateau where outcrops are largely missing. Because of the round shape of the samples and the patina which covers them all around it can be assumed that they have been transported from longer distance. According to the geological map of the

    The instantaneous values of the aerosol radiative forcing (ARF) at the surface and the top of the atmosphere (TOA) were calculated during desert dust events occurred at Granada (Southeastern Spain) from 2005 to 2010. For that, the SBDART radiative transfer model was utilized to simulate the global irradiance values (0.3-2.8 μm) at the surface and TOA using as input the aerosol properties derived from a CIMEL sun-photometer measurements and an inversion methodology that uses the sky radiance measurements in principal plane configuration and non-spherical particle shapes approximation. The SBDART modeled global irradiances at surface have been successfully validated against experimental measurements obtained by CM-11 pyranometer, indicating the reliability of the radiative transfer model used in this work for the ARF calculations. The monthly ARF values at surface ranged from -32 W m-2 to -46 W m-2, being larger in April and July than in the rest of months. The seasonal ARF evolution was inconsistent with seasonal aerosol optical depth (AOD) variation due to the effects induced by other aerosol parameter such as the single scattering albedo. The ARF at TOA changed from -9 W m-2 to -29 W m-2. Thus, the atmospheric ARF values (ARF at TOA minus ARF at surface) ranged from +15 to +35 W m-2. These results suggest that the African dust caused local atmospheric heating over the study location. The instantaneous aerosol radiative forcing efficiency (ARFE), aerosol radiative forcing per unit of AOD (440 nm), at surface and TOA during African desert dust events was evaluated according to the desert dust source origins. The ARFE values at surface were relatively high (in absolute term) and were -157 ± 20 (Sector A), -154 ± 23 (Sector B), and -147 ± 23 (Sector C) W m-2. These values were larger than many of the values found in literature which could be due to the presence of more absorbing atmospheric particles during African desert dust intrusions over our study area

    Mineral dusts can have profound effects on climate, clouds, ecosystem processes, and human health. Because regional dust emission and deposition in western North America are not well understood, measurements of total suspended particulate (TSP) from 2011 to 2013 were made along a 500-km transect of five remote sites in Utah and Colorado, USA. The TSP concentrations in μg m-3 adjusted to a 24-h period were relatively high at the two westernmost, dryland sites at Canyonlands National Park (mean = 135) and at Mesa Verde National Park (mean = 99), as well as at the easternmost site on the Great Plains (mean = 143). The TSP concentrations at the two intervening montane sites were less, with more loading on the western slope of the Rocky Mountains (Telluride, mean = 68) closest to the desert sites compared with the site on the eastern slope (Niwot Ridge, mean = 58). Dust concentrations were commonly highest during late winter-late spring, when Pacific frontal storms are the dominant causes of regional wind. Low concentrations (10), as revealed by relatively low average daily concentrations of fine (<5 μg m-3; PM2.5) and coarse (<10 μg m-3; PM2.5-10) fractions monitored at or near four sites. Standard air-quality measurements for PM2.5 and PM10 apparently do not capture the large majority of mineral-particulate pollution in the remote western interior U.S.

  3. SUSTAINABLE GROWTH: RECENT TRENDS ACROSS CENTRAL AND EASTERN EUROPEAN ECONOMIES

    Full Text Available What is economic growth? Although the answer to this question may seems of real simplicity, developing an accurate definition of this concept may constitute a real challenge both from a theoretical but also empirical point of view. This constant debate upon the concept of economic growth as well as indentifying the optimum set of instruments for quantifying it, constituted the starting point of the current article. The concept of economic growth is used nowadays complementary to terms like economic development, economic welfare or economic progress with reference to this complex process that implies macro-scale structures. Moreover indentifying the main factors that generate a significant impact upon the dynamics of the economic growth process, constitute a useful approach taking into consideration the high degree of heterogeneity that characterize the architecture of the economies around the world. If we develop this analysis across the European Union member states this debate became even more challenging due to the high degree of diversity that characterize these economies. Moreover, the Central and Eastern European countries and especially the ones that joined EU in 2004 and 2007 embody a set of particularities that make them extremely different from the rest of the European Union member states, features related to the historical background, economic policies and common efforts to intensify the convergence process with the more developed EU members. This paper studies the impact of two main factors upon the economic growth process namely an endogenous-exogenous factor like the degree of openness and an endogenous factor like the human capital using a complex dynamic panel method. The arguments that were in favour of choosing this two factors are on one hand the multitude of theoretical studies that argued the importance of them in modelling the economic growth process and on the other hand the small number of studies that use panel methods in

  4. Potential Impacts of Climate Change on Modern Recharge in the Eastern Desert and Sinai Peninsula of Egypt

    Aquifers in Egypt (e.g., Nubian Sandstone, shallow alluvial) were primarily recharged in previous wet climatic periods in the Quaternary. Previous studies have shown that both aquifers are receiving modern recharge under the current drier climatic conditions. The validity of these advocated models was tested using geophysical (conventional Electrical Resistivity, [ER]) and isotopic (O, H) data, and estimates for modern recharge were obtained using continuous rainfall-runoff modeling over the period 1998-2007. First-order estimates of the average annual modern recharge for the NSS aquifer (~13.0 x 10^6m^3/yr) and the shallow Alluvial aquifers in the Sinai Peninsula for the investigated watersheds (456 x 10^6m^3/yr) and the shallow Alluvial aquifers in the Eastern Desert (147 x 10^6m^3/yr) were computed using the SWAT (Soil Water Assessment Tool) model and readily available global remote sensing data sets (e.g., TRMM). Projections of climate change over North Africa from three of the leading general circulation models (GCMs) (GISS, GFDL, and UKMO) indicate a potentially high degree of vulnerability in the future precipitation amounts in Egypt. For each of the major watersheds and the Nubian Sandstone outcrops, we ran the calibrated model over the investigation period (1998-2007) using the obtained average annual precipitation and additional values of 10, 50, 100, and 150 mm. The SWAT model outputs were then used to extract relationships describing variations in runoff, recharge, and evaporation in relation to average annual precipitation amounts. Using developed tools on a web-based GIS interface we described these relationships under various climatic trends. Using a 10% decrease in rainfall in Egypt results in decreasing the average annual recharge to the shallow Alluvial aquifers in the Sinai Peninsula (384 x 10^6m^3/yr) and in the Eastern Desert (111 x 10^6m^3/yr). The observed differences between the watersheds in the partitioning of precipitation and in their

    Widespread, organic-rich diatomaceous deposits are evidence for formerly wetter times along the margins of the central Atacama Desert, one of the driest places on Earth today. We mapped and dated these paleowetland deposits at three presently waterless locations near Salar de Punta Negra (24.5°S) on the western slope of the Andes. Elevated groundwater levels supported phreatic discharge into wetlands during two periods: 15,900 to ~ 13,800 and 12,700 to ~ 9700 cal yr BP. Dense concentrations of lithic artifacts testify to the presence of paleoindians around the wetlands late in the second wet phase (11,000?–9700 cal yr BP). Water tables dropped below the surface before 15,900 and since 8100 cal yr BP, and briefly between ~ 13,800 and 12,700 cal yr BP. This temporal pattern is repeated, with some slight differences, in rodent middens from the study area, in both paleowetland and rodent midden deposits north and south of the study area, and in lake level fluctuations on the adjacent Bolivian Altiplano. The regional synchroneity of these changes points to a strengthening of the South American Monsoon — which we term the "Central Andean Pluvial Event" — in two distinct intervals (15,900–13,800 and 12,700–9700 cal yr BP), probably induced by steepened SST gradients across the tropical Pacific (i.e., La Niña-like conditions).

    In the early nineties the region of Central and Eastern Europe (CEE, more than 1 million km² and 100 million inhabitants) went through fundamental political, economic and social changes which eventually led to the European integration process. This positively influenced urban water and wastewater management , which had an unbalanced structure and rather low level of development. The paper outlines first the 1990 situation (water supply, sewerage and wastewater treatment (WWT)) and the infrastructure development of the last two decades, on the basis of a comprehensive data collection for six countries (Bulgaria, the Czech Republic, Hungary, Poland, Romania and Slovakia). Austria serves as a reference basis. Alterations of some of the drivers such as GDP (Gross Domestic Product), water tariff, investment funding and legislation are studied in detail. Then, the paper focuses on WWT by analyzing data of 20 large plants. Influent and effluent quality is evaluated. Technology indicators are estimated and assessed. They include plant removal rates and violation ratios assuming the application of the Urban Wastewater Directive, primary clarifier removal rates, actual anoxic volume and sludge age in comparison with the recommendations of the ATV guideline, criteria of secondary settling tanks and energy consumption. Finally, nutrient removal rates and upgrading options are outlined.

    Full Text Available In the context of the recent financial crisis, the macroeconomic stability of most countries has been cast to shadow. The damage to the economy caused by high inflation, volatile exchange rates, increasing amount of debts and the unstable financial markets has heavily left its toll on the global market and has led to massive unemployment and increasing poverty. This paper aims to follow the eight new Central and Eastern European countries that joined the European Union in 2004, as well as Romania and Bulgaria, who followed suit in 2007, in what concerns their economical performance, following adhesion to the EU while also comparing the periods before and after the economical crisis. They were chosen as a topic of research for the severity with which the crisis affected them and the high degree of reform implementation in the aftermath. It also plans to highlight the effect of the new reforms and the growth potential when compared to the rest of the European Union. The price inflation, real GDP growth, the levels of (unemployment, fiscal policy and stability of exchange rates will provide a clear image of how this cluster of developing countries fare nowadays against the rest of the EU countries.

    2015-12-01

    We present results of a Receiver Function (RF) study of the mantle transition zone (TZ) in Central-Eastern Greenland. The base of this study is data from 19 broad-band seismometers, which were temporarily installed from 2009 to 2012 in the region between Scoresbysund and Summit (~ 70º N) plus 5 permanent stations from the GLISN network. One half of these stations were installed on the ice, the other half on bedrock.Our analysis is based on low frequency PRF, which use the difference in travel times between converted and not converted phasesat discontinuities. Most of our RFs show clear signals for P410s and P660s. Their delay times suggest a surprisingly thin mantle transition zone for most parts of the study area in comparison to standard Earth models, and much thinner than below other continental shield and platform areas. This could indicate a fairly recent heating of the TZ. Another observation is an M-shaped signal around the 410 km - discontinuity at some of the stations mainly in the western part around Summit. This observation is contrary to the expected simple negative signal. It may indicate a thin low velocity layer between 410 km and 520 km, as it has previously been observed in several settings based on converted waves and also explosion data. Most of our stations show positive travel time anomalies for the upper mantle, which again is contrary to simple models of old continental shields.

  10. Institutional Determinants of International Migration from Central-Eastern Europe

    Full Text Available The aim of this paper is to present the role of institutional determinants for international migration from Central and Eastern Europe. In the whole post-war period international mobility has been stimulated by economic incentives, such as income disparities and unemployment, and also by particular solutions in migration policies in the receiving countries. Ethnic and asylum procedures, selective labor recruitments, visas barriers, regularization programs have mostly directed and intensified labor migration from CEE countries.Recently the EU enlargement (and, consequently, opening of member states’ labor markets became another institutional enhancement for migrating. The 2004 accession of eight CEE countries has been followed by a massive flow from CEE to the UK and Ireland that, together with Sweden, opened their labor markets for migrant workers. In 2007 Bulgaria and Romania will gain the access into EU, but the directions of mobility has been already established for Romanian and Bulgarian citizens: the main destination countries are Italy and Spain. The dynamics of migration from Romania and Bulgaria to South Europe has been extraordinary high since around 2000, mainly due to low legislative barriers and high demand for low-paid work. Again, the institutional determinant, such as overall acceptance towards illegal, foreign workers and regularization programs, turned out to be decisive.

    The Gerf ophiolite is the largest mantle-derived complex in the Arabian-Nubian Shield (ANS). This ophiolitic complex extends for tens of kilometers in the south Eastern Desert (SED) of Egypt as part of the Allaqi-Heiani and Oneib-Sol Hamed suture zones. The ultramafic section of the Gerf ophiolite comprises serpentinites, serpentinized peridotites and minor pyroxenites. All rocks contain relics of original magmatic phases. The elevated Cr# (> 0.84) of Cr-spinels indicates that these rocks represent highly-depleted mantle residues after high degrees of melt extraction. Mineral and bulk-rock chemistry show that the Gerf ophiolite suite represents fragments of oceanic lithosphere that developed in fore-arc setting in a supra-subduction zone (SSZ) environment. The pyroxenites have a LREE-enriched pattern relative to the serpentinites while the serpentinized peridotites display depleted patterns [average (La/Yb)n = 0.56)]. Modeling of LREE suggests that the LREE-enriched pyroxenites and serpentinites could have been produced via contamination of their mantle source by crustal material and/or subduction-related slab fluids during the mantle evolution in a SSZ setting or soon after ophiolite assemblage obduction onto the continental crust. In contrast, the LREE-depleted serpentinized peridotites could have been generated through MORB melt/mantle rock reaction.

    Biological soil crusts (biocrusts) are ubiquitous in drylands globally. Lichens and mosses are essential biocrust components and provide a variety of ecosystem services, making their conservation and management of interest. Accordingly, understanding what factors are correlated with their distribution is important to land managers. We hypothesized that cover would be related to geologic and pedologic factors. We sampled 32 sites throughout the eastern Mojave Desert, stratifying by parent material and the age of the geomorphic surfaces. The cover of lichens and mosses on ‘available ground’ (L + Mav; available ground excludes ground covered by rocks or plant stems) was higher on limestone and quartzite-derived soils than granite-derived soils. Cover was also higher on moderately younger-aged geomorphic surfaces (Qya2, Qya3, Qya4) and cutbanks than on very young (Qya1), older-aged surfaces (Qia1, Qia2), or soils associated with coppice mounds or animal burrowing under Larrea tridentata. When all sites and parent materials were combined, soil texture was the most important factor predicting the occurrence of L + Mav, with cover positively associated with higher silt, very fine sand, and fine sand fractions and negatively associated with the very coarse sand fraction. When parent materials were examined separately, nutrients such as available potassium, iron, and calcium became the most important predictors of L + Mav cover.

    Full Text Available An assemblage of calcareous algae (dasycladaleans and halimedaceans is described from the Upper Cenomanian to Lower Turonian of the Galala and Maghra el Hadida formations (Wadi Araba, northern Eastern Desert, Egypt. The following taxa have been identified: Dissocladella sp., Neomeris mokragorensis RADOIČIĆ & SCHLAGINTWEIT 2007, Salpingoporella milovanovici RADOIČIĆ 1978, Trinocladus divnae RADOIČIĆ 2006, Trinocladus cf. radoicicae ELLIOTT 1968, and Halimeda cf. elliotti CONARD & RIOULT, 1977. Most of the species are recorded from the first time from Egypt. Three of the identified algae (T. divnae, S. milovanovici and H. elliotti also occur in Cenomanian limestones of the Mirdita zone, Serbia, suggesting a trans-Tethyan distribution of these taxa during the early Late Cretaceous. The abundance and preservation of the algae suggest an autochthonous occurrence which can be used for the characterization of the depositional environment. The recorded calcareous as well as the sedimentologic and palaeontologic context of the Galala Formation support an open-lagoonal (non-restricted, warm-water setting. The Maghra el Hadida Formation was mainly deposited in a somewhat deeper, open shelf setting. Calcareous algae (Halimeda cf. elliotti CONARD & RIOULT are restricted to one level in the uppermost Lower Turonian which indicates a brief return to shallow-water deposition after a significant deepening with maximum flooding during the early Early Turonian.

    , but the higher Xp and the lower Xa values make that these pollen types can also indicate source plants moderately. Allium, Leguminosae, Roseceae, Pedicularis and Compositae have low A scores (less than 0.5), high O and/or U scores, so they cannot indicate source plants clearly. Some other pollen types, such as Pinus, Picea, Betula, Quercus, Ulmus, Ephedra, Elaegnaceae, Ranunculaceae, Caryophyllaceae, Polygonaceae, Saxifragaceae, only appear in pollen assemblages, so their indication cannot be decided. Just like the pollen percentage ratios of Artemisia and Chenopodiaceae (A/C), the ratios of Ephedra and Artemisia (E/A), Nitraria and Ephedra (N/E) can also indicate the aridity of environment. In typical desert communities, A/C ratios are less than 0.5, E/A ratios are more than 0.1, and N/E ratios are less than 1. In steppe desert, A/C ratios are 0.5―2, E/A ratios are less than 0.1, and N/E ratios are more than 1.

  16. Health sector reforms in Central and Eastern Europe

    Directory of Open Access Journals (Sweden)

    2004-04-01

    Full Text Available The political and economic transition of the 1990s in the countries of central and eastern Europe has been accompanied by wide ranging health care reform. The initial Soviet model has given way to a variety of forms of health insurance. Yet, as this paper argues, reform has too often been preoccupied with ideological imperatives, such as provider autonomy and the creation of funds separate from government, and has given much less thought to the contribution that health care can make to population health. The paper begins by examining the changing nature of health care. It recalls how the Soviet model was able to provide basic care to dispersed populations at low cost but notes how this is no longer sufficient in the face of an increasingly complex health care environment. This complexity reflects several factors, such as the growth in chronic disease, the emergence of new forms of infectious disease, and the introduction of new treatments requiring integrated delivery systems. It reviews evidence on how the former communist countries failed to keep up with developments in the west from the 1970s onwards, at a time when the complexity of health care was becoming apparent. It continues by setting out a framework for the organisation of health care based on the goal of health gain. This involves a series of activities that can be summarised as active purchasing, and which include assessment of health needs, designing effective packages of care, and monitoring outcomes. It concludes by arguing that a new relationship is needed between the state and the organisations involved in funding and delivering health care, to design a system that will tackle the considerable health needs of the people who live in this region.

  17. Holocene environmental changes in the Gebel Umm Hammad, Eastern Desert, Egypt

    1999-01-01

    Gebel Umm Hammad in the Red Sea Mountains east of Quseir, Egypt, today enjoys small but irregular amounts of winter rain, enabling the widening of joint controlled openings in the Thebes Limestone. Cavities are especially affected by flaking, while rock fragmentation is more active on the outside. The sedimentological and botanical study of fan deposits at the outlet of a karstic shaft in the Tree Shelter showed the local Holocene environmental evolution. Three periods of different degree of aridity can be considered: (i) Before 8120±45 BP (UtC-5389), bedload aggradation points to rare but occasionally heavy rains, lasting for several hours, attaining intensities of more than 76 mm/h and covering some 20 km 2. Wadi flash floods occasionally attained bankfull stage. (ii) Since 8120±45 BP (UtC-5389), such heavy rains have not occurred in the Egyptian Red Sea Mountains. Instead, a more moderate but maybe wetter precipitation regime was established. The karstic shafts were active, and there was water and life in the desert. Two humid pulses can be distinguished within this period. The first occurs at ±8000 BP, the second between 6630±45 (GrN-22560) and 6770±60 BP (GrN-22562). (iii) After the last wet culmination, there was a gradual shift to drier conditions. Shortly after ±5000 BP, modern climatic conditions are believed to have been attained. Today, the occasional rain storms are less heavy than before ±8000 BP. Bankfull stage river floods do not occur. Instead, secondary channels are eroded in the wadi beds. The general arid character during the whole period and the inherent local and temporal variations in precipitation patterns might explain apparent aberrations between the palaeoenvironmental evolution of the Tree Shelter site and other remote study areas in Egypt and Sudan.

    Full Text Available This paper is concerned with a culturally distinctive relationship between breasts and contemporary art from Central Desert Aboriginal women. Contra to the dominant interpretation of these paintings as representations of ‘country’—cartographic ‘maps’ of the landscape, narratives of Dreaming Ancestors, flora, fauna, species—my argument is that these works bespeak a particular breasted experience and expression, a cultural way of doing and being in the world; what I want to call a breasted ontology.

    We studied the cost-effectiveness of cervical cancer prevention strategies in the Central and Eastern Europe and Central Asia (CEECA) region. The cost-effectiveness of human papillomavirus (HPV)16/18 vaccination of 12 year-old girls was calculated for 28 countries, under the assumption that vaccination prevents 70% of all cervical cancer cases and that cervical cancer and all-cause mortality rates are stable without vaccination. At three-dose vaccination costs of I$ 100 per vaccinated girl (currency 2005 international dollars), HPV16/18 vaccination was very cost-effective in 25 out of 28 countries using the country's gross domestic product (GDP) per capita as cost-effectiveness threshold (criterion by World Health Organization). A three-dose vaccination cost of I$ 100 is within the current range of vaccine costs in European immunization programs, and therefore our results indicate that HPV vaccination may be good value for money. To evaluate the cost-effectiveness of cervical cancer screening combined with vaccination, we calibrated a published simulation model to HPV genotype data collected in Slovenia, Poland, and Georgia. The screening interval was varied at 3, 6, and 10 years starting at age 25 or 30 and ending at age 60. In Slovenia and Poland, combined vaccination and 10-yearly HPV (DNA) screening (vaccination coverage 70%, screening coverage per round 70%) was very cost-effective when the cost of three-dose vaccination was I$ 100 per vaccinated girl. More intensive screening was very cost-effective when the screening coverage per round was 30% or 50%. In Georgia, 10-yearly Pap screening was very cost-effective in unvaccinated women. Vaccination combined with 10-yearly HPV screening was likely to be cost-effective if the three-dose vaccination cost was I$ 50 per vaccinated girl. To conclude, cervical cancer prevention strategies utilizing both HPV16/18 vaccination and HPV screening are very cost-effective in countries with sufficient resources. In low

    New detailed geologic mapping and geochronology of the Barstow Formation at Harvard Hill, 30 km east of Barstow, CA, help to constrain Miocene paleogeography and tectonics of the central Mojave Desert. A northern strand of the Quaternary ENE-striking, sinistral Manix fault divides the Barstow Formation at Harvard Hill into two distinct lithologic assemblages. Strata north of the fault consist of: a green rhyolitic tuff, informally named the Shamrock tuff; lacustrine sandstone; partially silicified thin-bedded to massive limestone; and alluvial sandstone to pebble conglomerate. Strata south of the fault consist of: lacustrine siltstone and sandstone; a rhyolitic tuff dated at 19.1 Ma (U-Pb); rock-avalanche breccia deposits; partially silicified well-bedded to massive limestone; and alluvial sandstone and conglomerate. Our U-Pb zircon dating of the Shamrock tuff by SHRIMP-RG yields a peak probability age of 18.7 ± 0.1 Ma. Distinctive outcrop characteristics, mineralogy, remanent magnetization, and zircon geochemistry (Th/U) suggest that the Shamrock tuff represents a lacustrine facies of the regionally extensive Peach Spring Tuff (PST). Here we compare zircon age and geochemical analyses from the Shamrock tuff with those of the PST at Stoddard Wash and provide new insight into the age of zircon crystallization in the PST rhyolite. Results of our field studies show that Miocene strata at Harvard Hill mostly accumulated in a lacustrine environment, although depositional environments varied from a relatively deep lake to a very shallow lake or even onshore setting. Rock-avalanche breccias and alluvial deposits near the base of the exposed section indicate proximity to a steep basin margin and detrital studies suggest a southern source for coarse-grained deposits; therefore, we may infer a southern basin-margin setting at Harvard Hill during the early Miocene. Our geochronology demonstrates that deposition of the Barstow Formation at Harvard Hill extended from before

    2016-12-01

    The upper Cretaceous Abu Khruq ring complex (ARC) is located in the South Eastern Desert of Egypt displays concentric zonation of syenitic rocks from quartz-rich syenite at the margin, through alkali feldspar syenite to nepheline syenite in the centre. The syenitic rocks occur with nepheline monzogabbro, volcanic rocks (phonolite and trachyte) and the quartz- and nepheline-bearing pegmatites. Rocks of contrasting composition (mafic and salic) exhibit sophisticate geometric relationships. The nepheline monzogabbroic rocks have pillowy xenoliths forms within the salic (nepheline syenite and quartz alkali feldspar syenite) rocks, suggesting synchronous emplacement of the mafic and salic magmas. Clinopyroxene analysis of mafic and salic plutonic rocks of the ARC revealed that the overall pyroxene trend suggesting that fractionation involved a late, progressive increase in Na, in a reaction of the type Ca Mg Fe2+↔Na Fe3+. The chemistry of the analysed amphiboles are compositionally similar to those from typical differentiated peralkaline suites. Geochemically, the complex is enriched in the LILE, HFSE and REE. The concentrations of the compatible elements (V, Sr and Ba) generally decrease with increasing silica, consistent with fractional crystallization. A generalised increase in the Nb/Ta from the nepheline monzogabbro to nepheline syenite compositions is attributed to titanite fractionation. All the rock samples show relative increment of the LREE content than the HREE indicating weak to steep fractionated REE patterns (La/Yb) from 9.43 to 10.86, and thus retaining the geochemical characteristics of anorogenic suites. The magma sources of ARC are not derived from normal primitive mantle. The early stages of differentiation involved extensive olivine and pyroxene fractionation, the fractionation of amphibole, titanite, magnetite, apatite and feldspar may have been involved in the genesis of the salic differentiated compositions. The deviation towards silica

    1981-01-01

    The basalt stratigraphy and geologic structures of eastern Umtanum Ridge have been mapped and studied in detail to help assess the feasibility of nuclear waste terminal storage on the Hanford Site in southeastern Washington State. Eastern Umtanum Ridge is an asymmetric east-west-trending anticline of Columbia River basalt that plunges 5 degrees eastward into the Pasco Basin. Geologic mapping and determination of natural remanent magnetic polarity and chemical composition reveal that flows of the Pomona and Umatilla Members (Saddle Mountains Basalt), Priest Rapids and Frenchman Springs Members (Wanapum Basalt), and Grande Ronde Basalt were erupted as fairly uniform sheets. The Wahluke and Huntzinger flows (Saddle Mountains Basalt) fill a paleovalley cut into Wanapum Basalt. No evidence was found to indicate Quaternary-age movement on any structures in the map area. The basalt strata on the south limb of the Umtanum anticline display relatively little tectonic deformation since Miocene-Pliocene time. Thus, the buried south flank of Umtanum Ridge may provide an excellent location for a nuclear waste repository beneath the Hanford Site.

    Full Text Available Detailed information on the chemical and physical properties of aerosols is important for assessing their role in air quality and climate. This work explores the origin and fate of continental aerosols transported over the Central Atlantic Ocean, in terms of chemical composition, number and size distribution, using chemistry-transport models, satellite data and in situ measurements. We focus on August 2005, a period with intense hurricane and tropical storm activity over the Atlantic Ocean. A mixture of anthropogenic (sulphates, nitrates, natural (desert dust, sea salt and chemically aged (sulphate and nitrate on dust aerosols is found entering the hurricane genesis region, most likely interacting with clouds in the area. Results from our modelling study suggest rather small amounts of accumulation mode desert dust, sea salt and chemically aged dust aerosols in this Atlantic Ocean region. Aerosols of smaller size (Aitken mode are more abundant in the area and in some occasions sulphates of anthropogenic origin and desert dust are of the same magnitude in terms of number concentrations. Typical aerosol number concentrations are derived for the vertical layers near shallow cloud formation regimes, indicating that the aerosol number concentration can reach several thousand particles per cubic centimetre. The vertical distribution of the aerosols shows that the desert dust particles are often transported near the top of the marine cloud layer as they enter into the region where deep convection is initiated. The anthropogenic sulphate aerosol can be transported within a thick layer and enter the cloud deck through multiple ways (from the top, the base of the cloud, and by entrainment. The sodium (sea salt related aerosol is mostly found below the cloud base. The results of this work may provide insights relevant for studies that consider aerosol influences on cloud processes and storm development in the Central Atlantic region.

    Full Text Available Emerging Economies from Central and Eastern Europe take steps to ensure growth through tourism. Although they do not have the cultural, historical and artistic potential of the most famous tourist destinations, these economies promote forms of tourism for which they have suitable conditions. For example, Hungary is famous for health tourism, Bulgaria has made progress in terms of coastal tourism and Romania tries to make known the rural area although it has all conditions for practicing a wide diversified range of tourism forms. In this paper we present statistics showing how the tourism industry looks for three Central and Eastern European countries and we do a brief comparative analysis.

    The interpretation of the basement tectonic map of the area indicated the presence of a set of unexposed subsurface basic dykes running generally in NNW–SSE direction controlling the courses of major wadis in the study area. This set of NNW–SSE basic dykes are dissected by a NE–SW fault system. These two sets of fault systems were found to be matched well with that obtained from the Landsat image and geological map. It was found that the pronounced NNW direction is a predominant structural trend controlling the structural framework of the area.

    Full Text Available Enlargement has become a fundamental priority of the European Union after the 90’s. Up to now seven rounds have been held for enlarging the Community which initially was made up of six Member States (Belgium, Germany, France, Italy, Luxembourg, Netherlands. Among all EU enlargements, the eastward enlargement from 2004 was the biggest challenge, both due to the number of new Member States which joined - the number of EU inhabitants increasing to approximately from 380 to 485 million, but also due to the difference of Gross Domestic Product between the old and new EU members. This paper aims to provide insights in European integration and absorption of European funds into the newest that joined the European Union. The paper proposes an analysis of integration and specialization in Eastern Europe by means of data and statistics provided by European and national statistics institutions.

    Full Text Available The Abu Rushied area, situated in the South Eastern Desert of Egypt is a distinctive occurrence of economically important rare-metal mineralization where the host rocks are represented by granitic gneisses. Correspondingly, mineralogical and geochemical investigation of pegmatites pockets scattered within Abu Rusheid granitic gneisses revealed the presence of Hf-zircon, ferrocolumbite and uranyl silicate minerals (uranophane and kasolite. Electronmicroprobe analyses revealed the presence of Nb-Ta multioxide minerals (ishikawaite, uranopyrochlore, and fergusonite, uraninite, thorite and cassiterite as numerous inclusions in the recorded Hf-zircon and ferrocolumbite minerals.Abu Rusheid pegmatites are found as small and large bodies that occur as simple and complex (zoned pegmatites.Abu Rusheid rare-metal pegmatites occur as steeply dipping bodies of variable size, ranging from 1 to 5 m in width and 10 to 50 m in length. The zoned pegmatites are composed of wall zone of coarser granitic gneisses, intermediated zone of K-feldspar and pocket of mica (muscovite and biotite, and core of quartz and pocket ofmica with lenses of rare metals.The zircon is of bipyramidal to typical octahedral form and short prisms. Because the zircon of the investigated Abu Rushied pegmatite frequently contains hafnium in amounts ranging between 2.31 and 11.11%, the studied zircon was designated as Hf-rich zircon. This zircon commonly exhibits a normal zoning with rims consistentlyhigher in Hf than cores. The bright areas in the crystal either in core or rim showed a remarkable enrichment in hafnium content (8.83–11.11% with respect to the dark zones (3.19%. The investigated ferroclumbite commonly exhibits zoning; the dark zone is low in the Ta and U but the light zone is enriched in Ta (13% and U (1%. EMPAanalyses indicate the chemical composition of ishikawaite with U ranging from 0.68 to 0.79 per formula unit.Uranopyrochlore species has dominant uranium in the A

    Khedr, Mohamed Zaki; Arai, Shoji

    2016-10-01

    This paper details petrological and geochemical studies of an ultramafic-mafic intrusion in the Southern Eastern Desert of Egypt. The Dahanib complex shows a concentric zonation, from dunites at the core, through chromitites, clinopyroxene-rich dunites, wehrlites, harzburgites, gabbronorites and layered gabbros, to hornblende gabbros/diorites at the rim, similar to other Alaskan-type complexes. These lithologies typically feature cumulate textures and layering. Their pyroxenes (Mg#s, 0.54-0.94) evidence Fe, Mn and Na enrichment, but Al, Cr, Mg and Ti are depleted with differentiation. Their chromian spinels have a wide range of Cr# (0.31-0.61), along with high Ti and Fe, as a result of their origin through crystal accumulation and reaction with interstitial liquids. The clinopyroxenes (Cpxs) in peridotites and gabbroic rocks, which are high in REE concentration (2-100 times chondrite), are depleted in LREE relative to HREE and are similar to Cpx crystallized from asthenospheric melts. The mineral inclusions in spinel, the chemistry of Cpx in peridotites (rich in Al, Cr, Na, Ti and ΣREE = 13.7), and the melts in equilibrium with Cpx suggest that the Neoproterozoic lithosphere were partially refertilized by trace asthenospheric melts. The early magmas were possibly enriched by Mg, Cr, Ni, Ti, V and Sr, while the evolved types were rich in Fe, Mn, Na, Li, Zr, Co and REE via crystal accumulation and the interaction with interstitial liquids. The Neoproterozoic sub-arc mantle in Egypt is chemically heterogeneous and generally low in Nb, Ta, Zr and K, due to the low solubility of HFSE in slab-derived fluids and no other external addition of these elements. The large variations in lithology and chemistry, as well as the occurrence of scattered chromitite clots in the Dahanib peridotites, are related to a continuous supply of primitive magmas and/or the reaction between interstitial liquids and early cumulus crystals during multistage fractional crystallization.

    Stable isotope compositions have been determined for serpentinites from between Davos (Arosa-Platta nappe, Switzerland) and the Valmalenco (Italy). ??D and ??18O values (-120 to -60 and 6-10???, respectively) in the Arosa-Platta nappe indicate that serpentinization took place on the continent at relatively low temperatures in the presence of limited amounts of metamorphic fluids that contained a component of meteoric water. One sample of chrysotile has a ??18O value of 13??? providing evidence of high W/R ratios and low formation temperature of lizardite-chrysotile in this area. In contrast, relatively high ??D values (-42 to -34???) and low ??18O values (4.4-7.4???) for serpentine in the eastern part of the Valmalenco suggest a serpentinization process that took place at moderate temperatures in fluids that were dominated by ocean water. The antigorite in the Valmalenco is the first reported example of continental antigorite with an ocean water signature. An amphibole sample from a metasomatically overprinted contact zone to metasediments (??D=-36???) indicates that the metasomatic event also took place in the presence of ocean water. Lower ??D values (-93 to -60???) of serpentines in the western part of the Valmalenco suggest a different alteration history possibly influenced by fluids associated with contact metamorphism. Low water/rock ratios during regional metamorphism (and metasomatism) have to be assumed for both regions. ?? 1988 Springer-Verlag.

  4. Eastern, Central and Western Hungary – variations of Neolithisation models

    Full Text Available Until recent times, the Carpathian Basin was regarded as a uniform zone of neolithization. In the last few years it has become clear that at least three different types of transitions can be distinguished in the Eastern Plain (Alföld region: one in the Jászság area with authentic Mesolithic sites, one in the northern, one in the northeastern fringes of the Körös distribution area, and a further one in the southern part of the Danube–Tisza Interfluve where the impact of the formative Vinča culture must also be reckoned with. All regions differ from each other, concerning the contacts with Mesolithic population and the phases of neolithisation. Regarding Transdanubia, the picture becomes even more complex. The transition to the Neolithic obviously differed in each region: in the Drava valley where the Starčevo presence was very intensive, in the marshland around Lake Balaton, in the Rába valley lying close to the Alpine foreland, in the northern Transdanubian Danube valley and in the Little Hungarian Plain. Rejecting the simplifying model the assumption of a mosaic-like series of variations in the neolithisation process is offered. The process of Neolithisation is thus is far from being unified in the various regions. This short study tries to seek different models of neolithisation behind the differences.

  2. Transcriptome analysis of the desert locust central nervous system: production and annotation of a Schistocerca gregaria EST database.

    Directory of Open Access Journals (Sweden)

    Liesbeth Badisco

    Full Text Available BACKGROUND: The desert locust (Schistocerca gregaria displays a fascinating type of phenotypic plasticity, designated as 'phase polyphenism'. Depending on environmental conditions, one genome can be translated into two highly divergent phenotypes, termed the solitarious and gregarious (swarming phase. Although many of the underlying molecular events remain elusive, the central nervous system (CNS is expected to play a crucial role in the phase transition process. Locusts have also proven to be interesting model organisms in a physiological and neurobiological research context. However, molecular studies in locusts are hampered by the fact that genome/transcriptome sequence information available for this branch of insects is still limited. METHODOLOGY: We have generated 34,672 raw expressed sequence tags (EST from the CNS of desert locusts in both phases. These ESTs were assembled in 12,709 unique transcript sequences and nearly 4,000 sequences were functionally annotated. Moreover, the obtained S. gregaria EST information is highly complementary to the existing orthopteran transcriptomic data. Since many novel transcripts encode neuronal signaling and signal transduction components, this paper includes an overview of these sequences. Furthermore, several transcripts being differentially represented in solitarious and gregarious locusts were retrieved from this EST database. The findings highlight the involvement of the CNS in the phase transition process and indicate that this novel annotated database may also add to the emerging knowledge of concomitant neuronal signaling and neuroplasticity events. CONCLUSIONS: In summary, we met the need for novel sequence data from desert locust CNS. To our knowledge, we hereby also present the first insect EST database that is derived from the complete CNS. The obtained S. gregaria EST data constitute an important new source of information that will be instrumental in further unraveling the molecular

  3. Desert and desertification in Iran

    Bahrami, M.

    2009-04-01

    One of the greatest environmental concerns in Iran as in other arid and semiarid countries is the transformation of once productive, or marginally productive, land to deteriorated land and soil unable to support plants and animals. Because the land becomes barren and dry, the process is described as desertification, which occurs as a sequence of events. The area of deserts in Iran is about 340,000 Km2 (less than one fifth of its total area), of which 100,000 Km2 is being used for some cultivation, 120,000 Km2 is subjected to moving sands about 40 % of which is active sand dunes. Most of features and processes usual in world famous deserts are also observed in Iran: low precipitation, high evaporation, poor or lack of vegetation, saline and alkaline soils, low population and small and sparse oases. The deserts of Iran are generally classified in the subtropical, warm, arid and semiarid group, but the effect and presence of some geographical and geoclimatical factors such as height, vicinity to Indian Ocean and so on do some changes in climatic conditions and geographical features causing some local and regional differences in them. Geographically, two groups of deserts have been known in Iran: (1) Coastal deserts which, like a ribbon with variable width, stretch from extreme southeast to extreme southwest, at the north parts of Oman Sea and Persian Gulf. One important feature of these deserts is relatively high humidity which differentiates them from other deserts. This causes an increase in vegetation coverage and hence a decrease in eolian erosion and also a dominance of chemical weathering to that of physical. (2) internal deserts, which rest in central, eastern and southeastern plateau of the country and in independent and semi dependent depressions. This situation, which is due to the surrounding high mountains, blocks humidity entry and causes the aridity of these deserts. Wind as a dominant process in the area causes deflated features such as Reg (desert

  4. COUNTRIES’ SUSTAINABILITY TO ECONOMIC SHOCKS: THE STUDY OF CENTRAL AND EASTERN EUROPEAN MARKETS

    Full Text Available Purpose – to analyze economic “shock” impact on Central and Eastern European countries’ sustainable economic development. Design/methodology/approach – Statistical data has been analyzed and sustainability theory has been applied to Central and Eastern European countries during economic downturn 2008 – 2012. Findings – Findings suggest that commonly used macroeconomic indicators do not reflect stable social economic development. Moreover, usually high economic growth during economic cycle is determent by high level of recession in economic cycle. This finding suggests that investors and other financial decision makers should take into account the sustainability of economic performance before taking financial decisions so that during financial economic recession could mitigate risks and loses in Central and Eastern European markets. Also the impact of intangible capital on countries’ sustainability was identified. There is a relationship between social and economic sustainability and intangible capital. Research limitations/implications – Research is applied in the theory of sustainable economic development. The economic and social performance is being considered in the research. Although the concept of sustainable economic development is quite controversial in scientific literature, the aspects of economic and social indicators are taken into account not considering much of ecological aspects of sustainable development. The research logic is based on sustainability as constant and smooth social and economic development than the development through natural limitations and human being needs combinations. Practical implications – Practical implications might be broad enough. Identification of reaction of economies to natural economic “shock” during economic downturn might be applied for governments decision makers, investors, banks, exporters to evaluate future economic financial decisions in Eastern and Central European

    2013-06-01

    Full Text Available This review discusses the conference proceedings History of Art History in Central, Eastern and South-Eastern Europe. It focuses on the importance of the publication, and the fact that it highlights the almost complete ignorance of the historiography of art of central and eastern Europe, and also identifies a recurrent methodological deficit in many of the contributions, namely, their tendency to rely on a positivistic documentation of writers and texts with little analysis of their conceptual, aesthetic and ideological implications. The conference is thus an invaluable platform for further study, and also makes clear the need for more sophisticated critical interpretations.

    A detailed and well-dated proxy record of summer rainfall variation in arid Central Asia is lacking. Here, we report a long-term, high resolution record of summer rainfall extracted from a peat bog in arid eastern-Central Asia (AECA). The record indicates a slowly but steadily increasing trend of summer rainfall in the AECA over the past 8500 years. On this long-term trend are superimposed several abrupt increases in rainfall on millennial timescales that correspond to rapid cooling events in the North Atlantic. During the last millennium, the hydrological climate pattern of the AECA underwent a major change. The rainfall in the past century has reached its highest level over the 8500-year history, highlighting the significant impact of the human-induced greenhouse effect on the hydrological climate in the AECA. Our results demonstrate that even in very dry eastern-Central Asia, the climate can become wetter under global warming.

    2011-02-01

    Full Text Available The empirical record on PPP tests for transition economies is far from being so opulent as it is for the developed market economies. This paper attempts to fill this gap by scrutinizing the theory of PPP on a sample of Central and Eastern European economies. The paper has two main advances with respect to previous PPP studies. First, it employs a monthly data base on real exchange rates for a panel of 12 Central and Eastern European economies by testing the theory separately with respect to US dollar and with respect to Euro. Second, we utilise a panel unit root test that involves the estimation of the ADF regression in a SUR framework. Since our study found support for the validity of PPP in some reforming European economies, special attention should be devoted to individual country-specific factors that cause PPP deviations.

    Directory of Open Access Journals (Sweden)

    Irina BILAN

    2015-10-01

    Full Text Available The paper aims to empirically assess, using panel data estimation techniques, the effects of public indebtedness on economic growth for a group of 11 Central and Eastern European countries and over the period 1994-2013. Our hypothesis is that, although public indebtedness may fuel economic growth, once public debt breaches a certain threshold the effects are reversed and public indebtedness negatively affects GDP growth rates. The results of our study confirm this kind of relationship, with a maximum debt threshold for all countries of about 45-55% of GDP, lower for the less developed (like Romania and Bulgaria and higher for the more developed ones. Also, the threshold for Central and Eastern European countries is found to be lower than the one identified in other empirical studies for developed EU countries, as the former enjoy lower credibility, higher vulnerability to shocks and depend more on external capital transfers.

    This study assessed the effects of deforestation on the physical climate system of eastern and central Africa. The model used was the regional climate model (RegCM2) developed at the National Center for Atmospheric Research, and customized for the region under study. In the anomaly simulation, the land cover was systematically altered to replace the tropical forest with grass and Savannah cover. The RegCM2 realistically simulated the main features of the climate over eastern and central Africas. It was found that: (1) the rainfall dramatically decreased in 2 subregions, decreased in two subregions, increased in 1 subregion, and remained the same in 1 subregion; (2) rainfall deficit mainly happened during night time over the TF subregion and daytime over the LV subregion; and (3) mean surface air temperature increased over 5 subregions and decreased in 1 subregions. Deforestation also increased the diurnal variation of surface air temperature over one subregion. 12 refs., 2 figs., 3 tabs.

  11. Relocation of Business Services into Central and Eastern Europe (Evidence from Trade and Location Statistics

    Directory of Open Access Journals (Sweden)

    ZOLTÁN GÁL

    2014-06-01

    Full Text Available Relocation of business service offshoring-related activities measured by foreign direct investments and exports in services have grown rapidly after the Millennium in the new EU member states of Central and Eastern Europe (CEE. Besides Foreign Direct Investment (FDI, trade statistics support the assumption that an expanding export in business and in ICT services has been associated with relocation of shared services centres created by FDI in the six new member states (NMS. The service export data collected between 1996/2002 and 2012 gives a good proxy to identify those segments of service trade, which are considered to be offshorable. The paper examines the additional location factors selecting Central and Eastern European locations and summarises the effect of crisis on this industry. It concludes that the sector has demonstrated market resilience in the NMS and continued to expand rapidly.

  12. Migration Processes from Eastern and Central Europe in Spain: Legal Status, Social Identity and Job Placement

    Directory of Open Access Journals (Sweden)

    Mónica Ibáñez Angulo

    2009-01-01

    Full Text Available In Eastern and Central Europe, the collapse of the socialist model and the incorporation of the neoliberal model plunged the region into a deep economic and social crisis. In this context, emigration came to be viewed as a way out, at least on a temporary basis. Transnational migration from this region has also been interpreted as a response to the crisis of values generated following the collapse of the Socialist States. This text analyses migration flows from Eastern and Central Europe from three perspectives: politics (which defines their legal status; sociocultural (from whence their social identities and imaginaries are derived and the economic (which establishes specific forms of job placement. The aim of the study isto show that choosing migration destinations is not only determined by a rational economic logic, but also by political and socio-cultural factors; the study also stresses the point that social integration is a reciprocal, multidimensional process.

  13. Assessing the health benefits of improved air quality in Central and Eastern Europe

    Energy Technology Data Exchange (ETDEWEB)

    Krupnick, A.J.; Harrison, K.W.; Nickell, E.J.; Toman, M.A.

    Assessments of the benefits of improvements in environmental quality in Central and Eastern Europe are needed to determine priorities for pollution abatement activities in the region. A recent study conducted by researchers at Resources for the Future suggests that the human health benefits attributable to reductions in emissions of three air pollutants in five of the region's countries are potentially large. However, the study also highlights the uncertainties surrounding measurements of decreases in adverse health effects and economic valuations of improved air quality. Attempts to account for these uncertainties yield findings that strengthen the researchers' assertion that air pollution control should be a target of environmental and economic policies in Central and Eastern Europe.

    Study regionEastern and central Montana.Study focusFish in Northern Great Plains streams tolerate extreme conditions including heat, cold, floods, and drought; however changes in streamflow associated with long-term climate change may render some prairie streams uninhabitable for current fish species. To better understand future hydrology of these prairie streams, the Precipitation-Runoff Modeling System model and output from the RegCM3 Regional Climate model were used to simulate streamflow for seven watersheds in eastern and central Montana, for a baseline period (water years 1982–1999) and three future periods: water years 2021–2038 (2030 period), 2046–2063 (2055 period), and 2071–2088 (2080 period).New hydrological insights for the regionProjected changes in mean annual and mean monthly streamflow vary by the RegCM3 model selected, by watershed, and by future period. Mean annual streamflows for all future periods are projected to increase (11–21%) for two of the four central Montana watersheds: Middle Musselshell River and Cottonwood Creek. Mean annual streamflows for all future periods are projected to decrease (changes of −24 to −75%) for Redwater River watershed in eastern Montana. Mean annual streamflows are projected to increase slightly (2–15%) for the 2030 period and decrease (changes of −16 to −44%) for the 2080 period for the four remaining watersheds.

    The Chihuahuan Desert has been recognized as an important contributor of mineral aerosols emplaced into the atmosphere in the Western Hemisphere. Along with the production of these aerosols, growing concern has been stated relating the downwind transport of atmospheric dust particles to increases in human health related impacts such as asthma and bronchitis in the Binational Paso Del Norte, the largest urban area in the region. Efforts have been made to describe the source types (land use/cover) and frequency of emission from the "dust hotspots" or prevalent sources within the region. These studies have outlined specific areas and their related sedimentological environments responsible for the regular dust production. Ephemeral lakes, fluvial and alluvial related environments form the main natural dust producing landforms in the region, modulated by short-term climatic variability and anthropogenic disturbance. Analysis of remote sensing imagery shows that the margins between natural areas and agricultural lands form the main anthropogenic related source areas. Most of the previously published studies focus on these remotely sensed descriptions of the dust sources, while only a few deal with in situ or field characteristics of these sources. A formal and detailed description of the physicochemical properties of many of these areas is presented, providing key data on this component of the overall dust production cycle. Elemental and mineralogical compositions of dust source sediments, soil textural compositions (grain size distributions) and field sedimentological descriptions are presented as an effort to attain a detailed in situ description of the prevalent dust sources in the central part of the Chihuahuan Desert.

    This article provides an overview of cervical cancer and other human papillomavirus (HPV)-related diseases in Central and Eastern Europe (Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Montenegro, Poland, Romania, Serbia, Slovakia, Slovenia, and the Former Yugoslav Republic [FYR] of Macedonia) and Central Asia (Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Republic of Moldova, the Russian Federation, Tajikistan, Turkmenistan, Ukraine and Uzbekistan). Despite two- to three-fold variations, cervical cancer incidence rates are high in many countries in these two regions relative to other populations on the European and Asian continents. In Central and Eastern Europe, Romania and the FYR of Macedonia had the highest rates in 2008 alongside Bulgaria, Lithuania and Serbia, while in Central Asia, rates are elevated in Kyrgyzstan (the highest rates across the regions), Kazakhstan and Armenia. In each of these countries, at least one woman in 50 develops cervical cancer before the age of 75. The high cervical cancer burden is exacerbated by a lack of effective screening and an increasing risk of death from the disease among young women, as observed in Belarus, Tajikistan, Kyrgyzstan, Armenia, Azerbaijan, Ukraine, the Russian Federation and Kazakhstan. In several countries with longstanding cancer registries of reasonable quality (Belarus, Estonia and the Russian Federation), there are clear birth cohort effects; the risk of onset of cervical cancer is increasing in successive generations of women born from around 1940-50, a general phenomenon indicative of changing sexual behaviour and increasing risk of persistent HPV infection. There are limited data for other HPV-related cancers and other diseases at present in these countries. While options for reducing the HPV-related disease burden are resource-dependent, universal HPV vaccination with enhanced screening would maximally reduce the burden of

  2. Desert dust hazards: A global review

    Dust storms originate in many of the world's drylands and frequently present hazards to human society, both within the drylands themselves but also outside drylands due to long-range transport of aeolian sediments. Major sources of desert dust include the Sahara, the Middle East, central and eastern Asia, and parts of Australia, but dust-raising occurs all across the global drylands and, on occasion, beyond. Dust storms occur throughout the year and they vary in frequency and intensity over a number of timescales. Long-range transport of desert dust typically takes place along seasonal transport paths. Desert dust hazards are here reviewed according to the three phases of the wind erosion system: where dust is entrained, during the transport phase, and on deposition. This paper presents a synthesis of these hazards. It draws on empirical examples in physical geography, medical geology and geomorphology to discuss case studies from all over the world and in various fields. These include accelerated soil erosion in agricultural zones - where dust storms represent a severe form of accelerated soil erosion - the health effects of air pollution caused by desert aerosols via their physical, chemical and biological properties, transport accidents caused by poor visibility during desert dust events, and impacts on electricity generation and distribution. Given the importance of desert dust as a hazard to human societies, it is surprising to note that there have been relatively few attempts to assess their impact in economic terms. Existing studies in this regard are also reviewed, but the wide range of impacts discussed in this paper indicates that desert dust storms deserve more attention in this respect.

    The Betic Cordillera is an Alpine belt formed in the western Mediterranean by the westward displacement of the Alboran Domain in between the Eurasian and African convergent plates. New CGPS data from the central and eastern Betic Cordillera and its foreland-obtained mainly from the Topo-Iberia project-allowed us to precisely determine the rate of tectonic deformation. Most of the displacements of the central and eastern Betics are westward, with a variable southwestward component, in relation to the Eurasian stable plate. While in the Iberian foreland the displacements are extremely low, some deformation related to low compressional deformation occurs in the easternmost foreland basin and eastern Betic Cordillera. The displacement increases substantially southwards and westwards in relation to present-day extensional deformation. Major active discontinuities correspond to the NW-SE normal fault zones, which dip westwards; they are located in Almeria-Tabernas; Balanegra, and western Sierra de Gador; whereas the Padul fault zone located west of Sierra Nevada extends northwards to the Granada Basin. NW-SE extensional faults are also observed to the north, in the Baza Basin. Moreover, the activity of dextral faults along the Sorbas-Tabernas-Alpujarras-Guajares band, generally considered as a transfer fault zone, is evidenced by the displacement data. These results come to demonstrate the low activity or inactivity of the large northern E-W oriented folds of the central and eastern Internal Zone, such as the Sierra de Los Filabres antiform. They also point to the possible residual activity of the northern part of the NE-SW Sierra Nevada antiform, where the maximum relief of the Cordillera is found. Altogether, our data support a heterogeneous present-day westward extension that affects the upper crust of the Betic Cordillera and increases towards the thinned continental crust of the Alboran Sea and towards the west, which is compatible with roll-back subduction along

    The circulation patterns of persistent cold weather spells with durations longer than 10 days in central-eastern North America (United States and Canada; 32°-52°N, 95°-65°W) are investigated by using NCEP reanalysis data from 1948 to 2014. The criteria for the persistent cold spells are: (1) three-day averaged temperature anomalies for the regional average over the central-eastern United States and Canada must be below the 10th percentile, and (2) such extreme cold spells must last at least 10 days. The circulation patterns associated with these cold spells are examined to find the common signals of these events. The circulation anomaly patterns of these cold spells are categorized based on the El Niño-Southern Oscillation, Arctic Oscillation (AO), and other climate indices. The atmospheric circulation patterns that favor the cold spells are identified through composites of geopotential height maps for the cold spells. Negative AO phases favor persistent cold spells. Phases of sea surface temperature (SST) modes that are associated with warm SSTs in the eastern extratropical Pacific also favor persistent cold events in the study region. Stratospheric polar vortex breakdown alone is not a good predictor for the regional extreme cold spells in central-eastern North America. The meridional dispersions of quasi-stationary Rossby waves in the Pacific-North America sector in terms of cut-off zonal wavenumber modulated by background flow are analyzed to provide insight into the difference in evolution of the cold spells under different mean AO phases. The waveguide for AO > 1 is in a narrow latitudinal band centered on 40°N, whereas the waveguide for AO <-1 is in a broader latitudinal band from 40° to 65°N. The circulation patterns and lower boundary conditions favorable for persistent cold spells identified by this study can be a stepping-stone for improving winter subseasonal forecasting in North America.

  5. Comparison Of Patterns Of Convergence Among “Emerging Markets” Of Central Europe, Eastern Europe And Central Asia

    Full Text Available Based on analysis of economic growth indicators for 1989-2014, this article distinguishes the “emerging markets” of Central and Eastern Europe (with Russia included, from the other economies that fall in the broad ‘emerging markets’ category. Following the post–1989 reforms, the countries of the region share many of the same typical institutional features as other “emerging economies”, but not necessarily the associated economic outcomes. What characterizes “emerging economies” is that they grow fast enough to systematically close the distance dividing them from the advanced economies, creating convergence. Departing from this pattern, Central and Eastern Europe (and Russia have so far fallen short in terms of the growth rates, and the region as a whole has not made much progress in catching up. By more than doubling its national product Poland is the only notable exception in the region, although Slovenia may fit in the same category. At the other extreme, some of the economies actually lost two decades in terms of reducing the gaps, and some even fell further behind (e.g., Serbia, Ukraine. These findings have potentially serious implications for economic theory in general and for the presumption that globalization processes act as a unifying developmental force.

    Ambient ozone (O{sub 3}) concentrations in the forested areas of the Central and Eastern European (CEE) mountains measured on passive sampler networks and in several locations equipped with active monitors are reviewed. Some areas of the Carpathian Mountains, especially in Romania and parts of Poland, as well as the Sumava and Brdy Mountains in the Czech Republic are characterized by low European background concentrations of the pollutant (summer season means {approx}30 ppb). Other parts of the Carpathians, especially the western part of the range (Slovakia, the Czech Republic and Poland), some of the Eastern (Ukraine) and Southern (Romania) Carpathians and the Jizerske Mountains have high O{sub 3} levels with peak values >100 ppb and seasonal means {approx}50 ppb. Large portions of the CEE mountain forests experience O{sub 3} exposures that are above levels recommended for protection of forest and natural vegetation. Continuation of monitoring efforts with a combination of active monitors and passive samplers is needed for developing risk assessment scenarios for forests and other natural areas of the CEE Region. - Ozone concentrations in Central and Eastern European mountain ranges are elevated and phytotoxic to sensitive vegetation.

  7. Analysis of source spectra, attenuation, and site effects from central and eastern United States earthquakes

    1998-02-01

    This report describes the results from three studies of source spectra, attenuation, and site effects of central and eastern United States earthquakes. In the first study source parameter estimates taken from 27 previous studies were combined to test the assumption that the earthquake stress drop is roughly a constant, independent of earthquake size. 200 estimates of stress drop and seismic moment from eastern North American earthquakes were combined. It was found that the estimated stress drop from the 27 studies increases approximately as the square-root of the seismic moment, from about 3 bars at 10{sup 20} dyne-cm to 690 bars at 10{sup 25} dyne-cm. These results do not support the assumption of a constant stress drop when estimating ground motion parameters from eastern North American earthquakes. In the second study, broadband seismograms recorded by the United States National Seismograph Network and cooperating stations have been analysed to determine Q{sub Lg} as a function of frequency in five regions: the northeastern US, southeastern US, central US, northern Basin and Range, and California and western Nevada. In the third study, using spectral analysis, estimates have been made for the anelastic attenuation of four regional phases, and estimates have been made for the source parameters of 27 earthquakes, including the M{sub b} 5.6, 14 April, 1995, West Texas earthquake.

    Full Text Available Vertical ozone profiles measured in the period 1996–2002 in the framework of the MOZAIC project (Measurement of Ozone and Water Vapor by Airbus in Service Aircraft for flights connecting Central Europe to the Eastern Mediterranean basin (Heraklion, Rhodes; Antalya were analysed in order to evaluate the high rural ozone levels recorded in the Mediterranean area during summertime. The 77 flights during summer (JJAS showed significantly (10–12 ppb, 20–40% enhanced ozone mixing ratios in the lower troposphere over the Eastern Mediterranean frequently exceeding the 60 ppb, 8-h EU air quality standard, whereas ozone between 700 hPa and 400 hPa was only slightly (3–5 ppb, 5–10% higher than over central Europe. Analysis of composite weather maps for the high and low ozone cases, as well as back-trajectories and vertical profiles of carbon monoxide, suggest that the main factor leading to high tropospheric ozone values in the area is anticyclonic influence, in combination with a persistent northerly flow in the lower troposphere during summertime over the Aegean. On the other hand the lowest ozone levels are associated with low-pressure systems, especially the extension of the Middle East low over the Eastern Mediterranean area.

    Full Text Available The Silk Road Economic Belt, a strategic priority of the Chinese foreign policy in 2015, draws the attention to the countries of Central and Eastern Europe through the multiple benefits that it displays (investments, economic growth, trade between the countries along its corridors, job creation, infrastructure development, the strategic importance of being part of a grandiose multi-continental project. Among these benefits an important one is represented by the opportunities of Chinese investments in infrastructure, since the EU is suffering from a credit restraint. Also, The Silk Road Economic Belt could lead to a potential increase in the bilateral trade. Analyzing the literature in the field and the various official information available online, this paper aims to depict the Chinese project form the Eastern European perspective, identifying local priorities, conflicting interests, possible infrastructure projects, routes, focusing on two strategic countries in the region: Romania and Serbia, both displaying advantages and disadvantages.

    Full Text Available The present paper aims to examine the trends of the last decade and a half of central banks independence (CBI in Central and Eastern European countries on the road to the euro adoption and to compare the results with those identified in the case of the European Central Bank (ECB. We approached CBI from the perspective of monetary policy strategies central banks (CBs use. The main results show increasing independence during the selected time frame for all monetary authorities subject to analysis, regardless of the applied monetary policy strategy; superior average levels of CBI in CEE countries oriented to inflation targeting compared to those using the exchange rate as nominal anchor; higher degree of independence of ECB in relation to monetary authorities that use an inflation targeting strategy; the simultaneous presence of a significant level of independence, low inflation and stronger economic development in CEE members where CB is geared towards inflation targeting compared to CBs that implement a strategy of exchange rate targeting.

    Full Text Available Research work on the adverse effects of noise on annoyance in adults is well documented in Western Europe, but there is a knowledge gap concerning this type of research in Central and Eastern Europe (CEE, South-East Europe (SEE, and Newly Independent States (NIS. The objective of this review was to present findings and to propose future research directions for the studies on the effects of environmental noise on annoyance in adults conducted in these countries. After systematic search in accessible databases, scientific journals, conference proceedings, international and national reports in English and other languages, the authors identified 29 papers to be included to this review: 24 papers related to annoyance due to road traffic noise and 5 papers related to annoyance from other noise sources. In most of the identified studies, a cross-sectional design prevailed and the evaluations were mainly performed subjectively. The lack of recent annoyance studies related to railway and aircraft traffic noise was identified. Only two studies from NIS countries used noise exposure data for the evaluation of population annoyance according to the European Environmental Noise Directive (END. Capacity building in CEE, SEE, and NIS countries is necessary to acquire the "know-how" on how to implement and use the different scenarios for evaluating population annoyance by environmental noise, depending on the availability and suitability of noise exposure data. Particular attention should be given to the possible use of END noise exposure data, where applicable.

    Full Text Available Many reviews have documented the adverse effects of noise on children′s health, but the international scientific community was previously unfamiliar with noise research in Central and Eastern Europe (CEE, South-East Europe (SEE, and Newly Independent States (NIS. The aim of this review was to present studies on the effects of noise on children′s health, conducted in aforementioned countries in the second half of the 20 th century, interpret their findings, and criticize their methodology and results wherever possible. This review focused on 30 papers published in national journals in the period from 1965 to 2000. By design, 22 studies were observational and cross-sectional, and eight studies were experimental. The outcomes under the study included auditory changes, stress reactions, sleep disturbances, school performance, upright posture, and vegetative functions. Researchers from CEE, SEE, and NIS were the pioneers in the assessment of noise-induced changes of vegetative functions and blood pressure of children in urban areas, as well as of infants exposed to noise in incubators. Future research should focus on intervention studies and follow-up of children′s health in relation to noise exposure.

Evaluating regional differences in macroinvertebrate communities from forested depressional wetlands across eastern and central North America. J. N. Am. Benthol. Soc. 24(2):403-414. Abstract. Forested depressional wetlands are an important seasonal wetland type across eastern and central North America. Macroinvertebrates are crucial ecosystem components of most forested depressional wetlands, but community compositions can vary widely across the region. We evaluated variation in macroinvertebrate faunas across eastern and central North America using 5 published taxa lists from forested depressional wetlands in Michigan, Ontario, Wisconsin, Florida, and Georgia. We supplemented those data with quantitative community descriptions generated from 17 forested depressional wetlands in South Carolina and 74 of these wetlands in Minnesota. Cluster analysis of presence/absence data from these 7 locations indicated that distinct macroinvertebrate communities existed in northern and southern areas. Taxa characteristic of northern forested depressionalwetlands included Sphaeriidae, Lumbriculidae, Lymnaeidae, Physidae, Limnephilidae, Chirocephalidae, and Hirudinea (Glossophoniidae and/or Erpodbellidae) and taxa characteristic of southern sites included Asellidae, Crangonyctidae, Noteridae, and Cambaridae. Quantitative sampling in South Carolina and Minnesota indicated that regionally characteristic taxa included some of the most abundant organisms, with Sphaeriidae being the 2nd most abundant macroinvertebrate in Minnesota wetlands and Asellidae being the 2nd most abundant macroinvertebrate in South Carolina wetlands. Mollusks, in general, were restricted to forested depressional wetlands of northern latitudes, a pattern that may reflect a lack of Ca needed for shell formation in acidic southern sites. Differences in community composition probably translate into region

    The geodynamic settings of the Precambrian mafic-ultramafic complexes in the Eastern Desert of Egypt have important bearing on understanding the geotectonic evolution of the Arabian Nubian Shield. We present a detailed petrological study on a layered mafic-ultramafic intrusion that is located at the contact between the Precambrian continental crust and the Miocene Red Sea oceanic crust. The Motaghairat layered intrusion consists of basal lherzolite, orthopyroxenite, troctolite, olivine gabbro and anorthosite on the top. Variations in modal mineralogy and mineral chemistry along with the chemical composition of these units suggest their derivation from a common high-Mg tholeiitic parent melt through fractional crystallization processes. The parental magma was derived from a metasomatised mantle source. The primitive mantle-normalized patterns of the calculated melts exhibit enrichment in U relative to Th and Ba relative LREE which indicate that the enriched lithospheric mantle source was metasomatised by fluids derived from a subducted oceanic crust rather than by a sediment melt. Geological and petrological evidences suggest that the layered Motaghairat intrusion was emplaced during post-orogenic extension following subduction break-off and lithospheric delamination after the collision between the amalgamated island arc terranes and the Saharan Metacraton. The heat source required to melt the metasomatised lithospheric mantle was derived from the upwelling of hot asthenosphere after the subduction-break-off.

    The Neoproterozoic Atud diamictite in Wadi Kareim and Wadi Mobarak in the Eastern Desert of Egypt and the Nuwaybah formation in NW Saudi Arabia consist of poorly sorted, polymictic breccia, with clasts up to 1 m of granitoid, quartz porphyry, quartzite, basalt, greywacke, marble, arkose, and microconglomerate in fine-grained matrix. Stratigraphic relations indicate that the diamictite was deposited in a marine environment. Integrated field investigation, petrographic study and U-Pb SHRIMP zircon ages demonstrate that the Atud and Nuwaybah are correlative. The distribution of zircon ages indicate that ~750 Ma ages are dominant with a significant component of older materials, characterized by minor Mesoproterozoic and more abundant Paleoproterozoic and Neoarchean ages. Some matrix and metasedimentary clast zircons yield ages that are a few 10s of Ma younger than the age of the youngest clast (754 ± 15 Ma), suggesting Atud/Nuwaybah diamictite deposition ~750 Ma or slightly later, broadly consistent with being deposited during the Sturtian glaciation (740-660 Ma). The Paleoproterozoic and Neoarchean clasts have no source within the ensimatic Arabian-Nubian Shield. The distribution of the pre-Neoproterozoic ages are similar to the distribution of the pre-Neoproterozoic ages in Yemen and Saharan Metacraton, suggesting that these clasts have been transported hundreds of kilometers, maybe by ice-rafting. The Atud diamictite may represent important evidence for Cryogenian “Snowball Earth” in the Arabian-Nubian Shield.

    Full Text Available The present study investigates long-term developments in inward and outward FDI of 10 Central and Eastern European (CEE countries using Dunningĺs investment development path (IDP paradigm as a theoretical framework. Its main purpose is to determine how far the CEE countries have progressed along their IDPs since the beginning of transition. The results show that half of the analyzed countries have already reached Stage 3 of the IDP, while the other half are either firmly in Stage2 or are approaching Stage 3. With some notable exceptions, the study points to conformity of the analyzed IDP trajectories with Dunningĺs model.

    Full Text Available The paper explores the impact of foreign direct investment (FDI on income inequality in ten countries from Central and Eastern Europe (CEE in the period 1990 – 2012. First, the theoretical and empirical literature on the distributional effect of FDI is outlined. Second, we discuss briefly general trends in FDI inflow and income inequality in the countries from CEE after 1990. Third, we estimate several fixed effects regression models and find that FDI has the potential to exert influence on income inequality but this effect varies depending on the level of education and economic development of the host countries.

    Full Text Available Situation of lichens of aquatic and transient habitats in Eastern and East-Central European lowlands is discussed basing on example of several selected species: Leptogium biatorinum, Sarcosagium campestre, Steinia geophana, Verrucaria aquatilis, V. hydrela, V. praetermissa, V. xyloxena. Both habitat types are generally very much neglected in the region and all species show large spatial gaps in recording, which makes it difficult to judge both about their true distribution limits and spreading dynamics. On the other hand, targeted search through the suitable habitats and abundance of such indicate that many of these lichens are probably not uncommon in the region.

    This article offers a new empirical perspective on the state of Comparative Politics (CP) in Central and Eastern Europe (CEE). We present findings on the authors, methods, and epistemology of CP publications in the most relevant journals from eleven countries in the region. The major finding...... is that CP is rather marginal in CEE Political Science. Furthermore, CP articles predominantly focus on the authors' country of origin, use off-the-shelf data, apply mostly qualitative data analysis techniques, and rarely take a historical perspective. © 2013 European Consortium for Political Research....

    Full Text Available This paper examines the impact of corruption on foreign direct investment inflows for ten Central and Eastern European states. The paper attempts to answer the question: what is the role of corruption in attracting foreign direct investments? Using the data from UNCTAD for foreign direct investment and Corruption Perception Index from Transparency International, for a period of 12 years, 2000-2012, we evaluate the specific impact of corruptions on FDI using GDP as control variable. Our results confirm the majority of literature and show a negative significant relation between the variables analyzed, but at a lower intensity than expected.

    2015-03-01

    Full Text Available On the basis of Chinese written sources the author analyzes the internal and the external policies of Xieli Qaghan, the ruler of the Eastern Turkic Empire from 620 through 630. All throughout the history of the Empire the name of Xieli Qaghan is closely associated with the aggressive foreign policy of the Turks against China, as is the final defeat of the Eastern Turks and their troops by the Tang Emperor Taizong in 630. This article is the first attempt to see the events of the said period in a different light that is based on new information received from Chinese written sources, as well as the results of the modern climate research undertaken by Russian and foreign scientists. The article highlights the first stage of Xieli's rule (620–626 with its strong central government and its aggressive foreign policy towards its neighbors as a consequence, and the second period (627–630, when the Eastern Turkic Empire came under the rule of the Tang Emperor Taizong. The author analyzes the reasons of rising tension in the country of the Turks in 627–629, which led to the total collapse of the entire policy of Xieli Qaghan.

    The paper presents analyses based on information mainly from the National Communications of nine Central and Eastern European countries that are undertaking radical transition from centrally planned to market driven economics (EIT). It is designed primarily to provide an overview of the policies and measures to address climate change that have been implemented, or under implementation or planned. In order to better understand the objective of policies and measures and the way they have been implemented in EIT countries that analysis has been supplemented by a review of the national circumstances and overall policy contexts in EIT countries that are relevant to climate change policies and measures problems. Therefore, these issues will be discussed in the paper along with analysis of mitigation policies and measures by sector.

    The region of the Central and Eastern Europe is an area characterised by a relatively high seismicity. The active seismogenic structures and the related potentially destructive events are located in the proximity of the political boundaries between several countries existing in the area. An example is the seismic region between the NE Italy (FVG, Trentino-Alto Adige and Veneto), Austria (Tyrol, Carinthia) and Slovenia. So when a destructive earthquake occurs in the area, all the three countries are involved. In the year 2001 the Agencija Republike Slovenije za Okolje (ARSO) in Slovenia, the Department of Mathematics and Geoscience of the University of Trieste (DMG), the OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Italy and the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Austria signed an agreement for the real-time seismological data exchange in the Southeastern Alps region. Soon after the Interreg IIIa Italia-Austria projects "Trans-National Seismological Networks in the South-Eastern Alps" and "FASTLINK" started. The main goal of these projects was the creation of a transfrontier network for the common seismic monitoring of the region for scientific and civil defense purposes. During these years the high quality data recorded by the transfrontier network has been used, by the involved institutions, for their scientific research, for institutional activities and for the civil defense services. Several common international projects have been realized with success. The instrumentation has been continuously upgraded, the installations quality improved as well as the data transmission efficiency. In the 2013 ARSO, DMG, OGS and ZAMG decided to name the cooperative network "Central and Eastern European Earthquake Research Network - CE3RN". The national/regional seismic networks actually involved in the CE3RN network are: • Austrian national BB network (ZAMG - OE) • Friuli Veneto SP network (OGS - FV) • Friuli VG

    Full Text Available Countries from South-East Europe (SEE, Central and Eastern Europe (CEE and Newly Independent States (NIS are in the process of harmonization with European environmental noise legislation. However, research work on noise and health was performed in some countries independently of harmonization process of adoption and implementation of legislation for environmental noise. Aim of this review is to summarize available evidence for noise induced sleep disturbance in population of CEE, SEE and NIS countries and to give directions for further research work in this field. After a systematic search through accessible electronic databases, conference proceedings, PhD thesis, national reports and scientific journals in English and non-English language, we decided to include six papers and one PhD thesis in this review: One paper from former Yugoslavia, one paper from Slovakia, one paper from Lithuania, two papers from Serbia and one paper, as also one PhD thesis from The Former Yugoslav Republic of Macedonia. Noise exposure assessment focused on road traffic noise was mainly performed with objective noise measurements, but also with noise mapping in case of Lithuanian study. Sleep disturbance was assessed with the questionnaire based surveys and was assumed from dose-effect relationship between night-time noise indicator (Lnight for road traffic noise and sleep disturbance (for Lithuanian study. Although research evidence on noise and sleep disturbance show to be sufficient for establishing dose response curves for sleep disturbance in countries where studies were performed, further research is needed with particular attention to vulnerable groups, other noise sources, development of laboratory research work and common methodology in assessment of burden of diseases from environmental noise.

    Sand dunes are the main landforms in modern deserts worldwide. As an important type of desert vegetation, herbaceous plants have long been acknowledged for their important ecological functions. We focus on the dune-scale distribution pattern of herbaceous plants and their relationship with the environment. During the early summer of 2010, the herbaceous plant density, coverage, aboveground biomass and eighteen environmental factors were surveyed from 214 plots (5m×5m) across two linear sand dunes (220m×110m) located in the Gurbantunggut Desert, China, a typical saline-alkali desert in Central Asia. Data were analyzed using univariate, ordination, and geostatistical techniques. Three vegetation variables represent a significant clumped distribution (P<0.01) across the entire study site. Obvious differences were observed among different slope positions/transects, with the lowest values observed at the summit. Geostatistics indicated that all of the variables showed a moderate spatial dependence and obvious zonal distribution along the sand dunes. The ranges (lag distance) of density (32.2m) and coverage (33.5m) were close to the average width (31.4m) of the transects. The biomass range (74.1m) was almost equal to the average width (75m) of the sand dunes. Pearson's correlation analysis and nonmetric multidimensional scaling analysis consistently demonstrated that the distributions of herbs on sand dunes were dominantly influenced by sand dune topography (slope position, convexity, and relative height), soil nutrients (total nitrogen and phosphorus) and deep-rooted shrubbery (Ephedra distachya). Compared to large, mobile and steep sand dunes, low, fixed and gentle sand dunes contribute to herbaceous plant abundance and distribution as well as the stability maintenance of the whole desert ecosystem.

    Full Text Available The variable domain 1 (VD1 domain of the control region and a small segment of the rrnaL gene of the F mtDNA type were sequenced and analyzed in 174 specimens of Mytilus galloprovincialis. Samples were collected from eight locations in four Central-Eastern (CE Mediterranean countries (Italy, Croatia, Greece and Turkey. A new primer, specific for the F mtDNA type, was designed for the sequencing procedure. In total 40 different haplotypes were recorded, 24 of which were unique. Aside from the two populations situated in Thermaikos gulf (Northern Aegean, Greece, relatively high levels of haplotype and nucleotide diversity were estimated for both Central and Eastern Mediterranean populations. Eight out of the 40 haplotypes were shared by at least three populations while two of them were found in all populations. ΦST and cluster analysis revealed lack of structuring among CE Mediterranean populations with the exception of those located at the Sea of Marmara and Croatian coast which were highly differentiated. Apart from the species’ inherit dispersal ability, anthropogenic activities, such as the repeated translocations of mussel spat, seem to have played an important role in shaping the current genetic population structure of CE M. galloprovincialis mussels.

    Full Text Available After the fall of communism in the late ’80 in Central and Eastern Europe, due to the appearance of several political parties in each state, there was the need to form coalitions in order to provide support for the governments. This paper aims to identify the institutional features that influence the coalition formation process using the rational choice institutionalism approach. In this case, the political parties, who seek to optimize their benefits in the government formation process, are constrained by the institutional environment. The institutional environment comprises the rules that determine how the governments are formed. Particularly, this paper aim is to identify how the cabinet operating rules affect the outcomes of the coalition formation process. In order to do so, I will develop a quantitative analysis of 110 cabinets in Estonia, Latvia, Lithuania, Poland, Czech Republic, Slovakia, Hungary, Slovenia, Romania and Bulgaria formed after the first free elections subsequent to the communist fall until the beginning of 2010. These countries represent the post-communist states that joined the European Union, finalizing the democratization process at least from a formal point a view. This cross-country comparison tries to explain how some institutional features influence the formation of coalitions in new democracies. This research is valuable due to the lack of this type of comparative studies on Central and Eastern European states.

    Full Text Available Today’s Central and Eastern European aquaculture is based on low production intensity pondculture dominated by traditional extensive and semi-intensive carp-based polyculture technologies, useof complete feeds in pond culture is not prevalent. Meanwhile pond culture in other parts of the Worldhas gone through an intensification process, nowadays high-intensity monoculture technologies dominatein pond farming. Use of complete feeds and application of higher stocking rates have doubled-tripledyields compared to traditional extensive, semi-intensive farming methods. Economic analysis of Asianfarms shows that intensification leads to increased profits per unit area and decreased profitability. Thecalculation of financial results of fish farming technologies of different intensity level show the sameeffect of intensification on viability in Hungary as in Asia: high feeding and stocking rate result inoutstanding profit per unit area and decreased profit margin at the same time. Rising land prices (andrents, fees for usage of water, decrease in area-based subsidies can push the Central and EasternEuropean pond aquaculture toward intensification as high intensity fish rearing in ponds may offer goodalternative for those farmers who have limited access to land (pond area and water. However one musttake the increased risks of high intensity and must have good managing abilities and farming expertisewith special regard to water quality and biomass management.

    Full Text Available Towards the late 90’s, together with overcoming the shock of transition, most countries in Central and Eastern Europe began a process of profound reform of the pension systems. The aim of these reforms was mainly ensuring the financial sustainability of the pension systems often without taking into account their primary goal: to provide adequate retirement incomes, to allow the elderly to maintain a decent living standard after retirement and to have economic independence. However, a successful pension system is not the one that involves little spending but the one achieving its primary goal while limiting the future pressures on public finances.The economic crisis has increased the vulnerability of the pension systems. The economic recessions or slow economic growth, budget deficits and debt burdens, low employment rates have led to rising the concern about the ability of pension systems to fulfill their purpose. In this context, most Central and Eastern European countries have recently been forced to take up new changes in pensions. In our study we accomplished a comparative analysis of the pension systems’ performance based on calculating a composite indicator that includesthree components: the indicator of adequacy, the financial sustainability indicator and the indicator of modernity. Each of these components is obtained by aggregating a selection of sub-indicators. The purpose of this analysis is to identify best practices for successful reform, but also to highlight potentialhazards or imbalances that might face various emerging countries.

Realizamos muestreos con trampas bandeja y observaciones de visitantes florales en seis pares de sitios dentro y fuera de la reserva. Nuestros resultados sugieren que los treinta y cinco años de exclusión del ganado vacuno en Ñacuñán han tenido efectos detectables sobre la estructura del hábitat. Sin embargo, estos cambios en el hábitat se tradujeron sólo en efectos parciales y conflictivos sobre la riqueza de himenópteros, y no tuvieron efectos detectables sobre la composición de himenópteros.

    The vulnerability of dryland surfaces to wind erosion depends importantly on the absence or the presence and character of surface roughness elements, such as plants, clasts, and topographic irregularities that diminish wind speed near the surface. A model for the friction velocity ratio has been developed to account for wind sheltering by many different types of co-existing roughness elements. Such conditions typify a monitored area in the central Mojave Desert, California, that experiences frequent sand movement and dust emission. Two additional models are used to convert the friction velocity ratio to the surface roughness length (zo) for momentum. To calculate roughness lengths from these models, measurements were made at 11 sites within the monitored area to characterize the surface roughness element. Measurements included (1) the number of roughness species (e.g., plants, small-scale topography, clasts), and their associated heights and widths, (2) spacing among species, and (3) vegetation porosity (a measurement of the spatial distribution of woody elements of a plant). Documented or estimated values of drag coefficients for different species were included in the modeling. At these sites, wind-speed profiles were measured during periods of neutral atmospheric stability using three 9-m towers with three or four calibrated anemometers on each. Modeled roughness lengths show a close correspondence (correlation coefficient, 0.84-0.86) to the aerodynamically determined values at the field sites. The geometric properties of the roughness elements in the model are amenable to measurement at much higher temporal and spatial resolutions using remote-sensing techniques than can be accomplished through laborious ground-based methods. A remote-sensing approach to acquire values of the modeled roughness length is particularly important for the development of linked surface/atmosphere wind-erosion models sensitive to climate variability and land-use changes in areas such

    Dermacentor reticulatus tick is a vector and final host of Babesia canis canis, protozoan parasite of the dog. In Poland and other European countries, endemic regions for canine babesiosis caused by B. canis canis are the same as endemic regions for D. reticulatus. In many of these regions, canine babesiosis is the most prevalent tick-borne disease in dogs. In Europe, increasing range of geographical distribution of D. reticulatus is observed. A consequence of this fact may be increasing range of canine babesiosis. D. reticulatus is one of the most common ticks occurring in Poland, however, it occurs mainly in the north-eastern and eastern part of the country, and there are many areas in which this species has not been reported yet. In this study, D. reticulatus ticks were collected from March 2007 to November 2008 in central and eastern Mazowsze region, and in some localities in Białystok and Lublin regions. Twenty four new sites for D. reticulatus, mainly in central and eastern regions of Mazowsze Province have been found. 18 localities are placed on banks of the fishing ponds or in river valleys and 6 are forests borders or barren lands and meadows, not situated near rivers or other water reservoirs. All tick-rich sites are localized in river valleys or on pond banks. However, statistical analysis showed that there were no differences in the density of ticks between groups of areas. These results show that the occurrence of D. reticulatus in newly detected areas has became endemic. Probably woodless, unregulated river valleys are important migration tracts for this species of tick and enable them to penetrate new territories. It seems likely that geographical range of D. reticulatus is widening from east to west of Poland what can induce an increase in the number of canine babesiosis cases in areas non-endemic for B. canis canis and its vector. Climate change may be also partially responsible for earlier beginning of tick's seasonal activity as well as for

    The USArray Transportable Array (TA) is a network of 400 seismograph stations that is systematically moving west-to-east across the contiguous United States. The TA is part of the National Science Foundation's multi- disciplinary EarthScope program. The TA has already occupied over 700 stations in the western US, and is continuing its multi-year migration towards the Atlantic coast before heading for Alaska. The stations use a grid-like deployment with 70 km separation between stations. At any given time there are approximately 400 stations operational, occupying a nominal 800 km by 2000 km "footprint." Each station is operated for two years. TA stations consist of three component broadband seismometers, with a few sites in the westernmost United States also including three component strong motion instruments. The instruments are installed about two meters below the surface, in thermally stable vaults. All stations transmit continuous data in near-real-time, and the data are freely distributed through the IRIS Data Management Center. TA stations can be upgraded to incorporate high frequency or strong motion instrument. Organizations can also "adopt" stations after installation by reimbursing the cost of the hardware, so that the stations become permanent. The TA is presently operating in the swath of the country extending from Texas to Montana. From 2010 to 2013 the TA will occupy ~800 sites in the central and eastern US. The array will be centered on the New Madrid, MO region during the bicentennial of the 1811-1812 earthquakes. During the TA deployment every existing or planned nuclear plant in the eastern US will be within 70 km of at least four new seismic stations. Thus, this station deployment in the eastern half of the US presents an unprecedented opportunity for improving source characterization, modeling the regional velocity and attenuation structure, and mapping seismic zones down to low magnitude thresholds. We will provide an overview of TA

    Between late summer and mid-autumn, broad low-level cyclonic circulations with spatial scales of 1000-2000 km can develop over Central America on time scales of 1-2 days and persist for 3-5 days. These broad cyclonic circulation regions, which hereafter we will call gyres, can absorb westward-moving tropical cyclones (TCs) from the east (e.g., Matthew in September 2010), disgorge cyclonic circulations to the northeast that later develop into TCs (e.g., Nicole in September 2010), interact with remnant southward-moving cold fronts to encourage weak TC development (e.g., TC Nate in October 2011), or enable weak eastern Pacific tropical depressions (TDs) to make landfall in Central America (e.g., TD 12-E in October 2011). A distinguishing feature of a Central American gyre is that it can be directly associated with exceptionally heavy rainfall and damaging regional flooding, such as occurred in conjunction with the landfall of TD 12-E and TC Nate. Similarly, a deep poleward tropical moisture transport from a Central American gyre in response to amplified midlatitude flow can lead to flooding rains in midlatitudes such as occurred along the Atlantic coast in conjunction with TC Lee in September 2011. This presentation will focus on the large-scale flow contribution to the formation of a well-defined Central American gyre in late September 2010 during the PREDICT field experiment and the subsequent impact of the gyre on the midlatitude flow and weather over eastern North America. The gyre formed when a strong east-west oriented cyclonic shear zone that separated anomalous tropical westerlies in the eastern Pacific from anomalous tropical easterlies over the Caribbean and North Atlantic was disrupted by northerly flow across the Isthmus of Tehuantepec gap (Chivela Pass) into the tropical Pacific. Initially, anomalous easterly flow from the Caribbean that was deflected southward by higher terrain to the west provided the initial source of northerly flow through the gap

    Computation of probabilistic earthquake hazard requires an estimate of Mmax: the moment magnitude of the largest earthquake that is thought to be possible within a specified geographic region. The region specified in this report is the Central and Eastern United States and adjacent Canada. Parts A and B of this report describe the construction of a global catalog of moderate to large earthquakes that occurred worldwide in tectonic analogs of the Central and Eastern United States. Examination of histograms of the magnitudes of these earthquakes allows estimation of Central and Eastern United States Mmax. The catalog and Mmax estimates derived from it are used in the 2014 edition of the U.S. Geological Survey national seismic-hazard maps. Part A deals with prehistoric earthquakes, and this part deals with historical events.

    Studies of the paragenesis and U-Pb systematics of monazite in rocks from the eastern Mojave Desert, California, corroborate its potential usefulness as a prograde thermochronometer and in dating granite inheritance. Unmetamorphosed Latham Shale and its equivalents at grades ranging from greenschist to upper amphibolite facies are virtually identical in composition. Monazite is absent in the shale and low-grade schists, but it is abundant in schists at staurolite and higher grades. Lower-grade schists instead include minute Th- and Ce-oxides and unidentified Ce-poor LREE-phosphates that apparently are lower-temperature precursors to monazite. Thus monazite originates when the pelite passes through lower-amphibolite-facies conditions. Monazites from three Upper Cretaceous granites yield ages that are strongly discordant. Upper intercepts of 1.6-1.7 Ga are similar to those defined by U-Pb data for coexisting zircons and coincide with a period of copious magmatism in the Mojave crust. As the host Upper Cretaceous granitic magmas were all above 700??C, effective closure of the restitic monazites to Pb loss must be well in excess of this temperature. U-Pb compositions of monazite from Proterozoic granitoids and schist also indicate high Pb retentivity. Taken together, these studies support the suggestion that monazite can be an effective prograde thermochronometer. At least in pelites, it is not usually retained as a detrital mineral, but rather forms during moderate-temperature metamorphism. Its U-Pb system should not be reset by subsequent higher-grade metamorphism. ?? 1993.

    The 606 Ma old Abu Ziran granite of the Eastern Desert of Egypt intruded the southern margin of the Meatiq dome in a sinistral shear extensional setting. Its emplacement was enabled by a system of NW-trending sinistral shears, related Riedel shears and N-S extensional shear zones and faults. Magmatic flow was east-directed and controlled by Riedel shears that progressively rotated to an orientation favourable for extension. Strain markers that document magmatic flow show eastward decreasing strain together with strain increase from pluton centre to margins. This is explained by Newtonian flow between non-parallel plates and differences in flow velocities across the pluton. Solid state fabrics including shear fabrics, orientation of late magmatic dykes and quartz tension gashes, together with quartz C-axes distributions, document southward extensional shear within the solidified pluton and adjacent host rocks. Extensional shear is correlated with exhumation of the Meatiq dome coeval and soon after pluton solidification (585 Ma). Pressure temperature evolutionary paths, derived from fluid inclusions, show a clockwise path with exhumation by isothermal decompression in the Meatiq dome. By contrast, the overlying volcanosedimentary nappes experienced an anti-clockwise path released by temperature rise due to pluton emplacement followed by isobaric cooling. Quartz fabrics indicate high-temperature coaxial N-S flow in the northern Meatiq dome and lower-temperature, non-coaxial southward flow within the overlaying superficial nappe. This is explained by the exhumation process itself that progressively localised into simple shear domains when rocks approached higher crustal levels. Late extension at ca. 580 Ma was pure shear dominated and resulted in reversal of shear, now dextral, in the western Meatiq shear zone.

    Full Text Available The detrimental consequences of swelling soils are most apparent in arid and semi-arid regions. Sedimentary clays are mixtures of illite, kaolinite and some montmorillonite. There are various soil types liable to swell such as shale, mudstone, siltstone and marl due to the presence of Smectite group in these soils. Large volume changes of these types of soils can cause extensive damages to civil engineering infrastructures; roads, airport pavements, pipelines and shallow foundations. A number of localities in Egypt are well-known by the presence of swelling soils. Sohag – Safaga highway in the Eastern Desert of Egypt is considered to be an investable transportation road and one of the most important lateral connections between Upper Egypt and the Red Sea area. The study area is located in a buffer zone of 25 km from both sides of the highway. This area is believed to be more influenced by the road and could be fully utilized to share in developing areas in the road vicinity. The research objectives are to use recent ASTER satellite imageries with the aid of field samples to map different swelling clay minerals and compare between the different sensors accuracy in locating them within the buffer zone. Certain engineering measures should be considered to enable construction over these types of swelling soils. The results confirmed the presence of montmorillonite in this buffer zone and in the 5 km buffer around the road which represents a hazard especially for the future planned projects within this area.

    Haze is a serious issue in China with increasing concerns, and understanding the factors driving decadal-scale variations in haze occurrence is relevant for government policymaking. Using a comprehensive observational haze dataset, we demonstrate notable decadal fluctuations in the number of haze days (HD) during winter in central eastern China, showing a decline since the mid-1980s. The leading mode of the wintertime HD features an increasing trend for 1959-2012 in eastern China, highly correlated with China's gross domestic product (GDP) that represents increasing trend of pollutant emissions, and to a lesser extent meteorological factors. The second mode shows decadal variations in central eastern China associated with Pacific Decadal Oscillation (PDO). Observations and numerical simulations suggest that Mongolia High and corresponding descending motion tend to be enhanced (weakened) in central eastern China during the positive (negative) phase of PDO. With PDO shifting towards a negative phase, the weakened Mongolia High and ascending anomalies make the air unstable and conduce to the spread of pollutants, leading to the decline in the wintertime HD over central eastern China since the mid-1980s. Based on above physical mechanisms, a linear model based on PDO and GDP metrics provided a good fit to the observed HD.

    Full Text Available This paper analyzes the relationship between economic performance and institutional development in several Central and Eastern European Countries. Our meta-argument is that the structural transformations at the levels of the quantitative variables and mechanisms are only a part of the transition processes. In order to view the big picture, the qualitative aspects related to public policies and institutions should also be considered. We test the linkages between the quality of public policies and institutions for seven Central and Eastern European countries (Bulgaria, Poland, Czech Republic, Hungary, Slovenia, Slovakia and Romania for a time span between 2001 and 2011. These countries are displaying a certain degree of heterogeneity in terms of economic performances and the design and implementation of public policies. We use for our analysis the World Bank indicators from World Wide Governance Indicators. In order to deal with the potential reverse causality issues, we employ Generalized Method of Moments Framework (GMM by using the lagged variables as instruments. The impact of governance indicators is statistically significant even if we use several control variables: exchange rate, unemployment, current account deficit, taxes burden and price stability. The corresponding Sargan and Arellano-Bond test for zero autocorrelation in first-differenced errors tests shows that the results display a corresponding robustness. The main policy implications for our findings may be synthesized by the thesis, according to which a proper design of public policies, a high degree of their effectiveness and accountability, a stable social and political environment together with the rule of law and efficient anticorruption mechanisms are critical determinants of economic growth even in emerging markets.

    Agassiz's Desert Tortoises (Gopherus agassizii) spend >95% of their lives underground in cover sites that serve as thermal buffers from temperatures, which can fluctuate >40°C on a daily and seasonal basis. We monitored temperatures at 30 active tortoise cover sites within the Soda Mountains, San Bernardino County, California, from February 2004 to September 2006. Cover sites varied in type and structural characteristics, including opening height and width, soil cover depth over the opening, aspect, tunnel length, and surficial geology. We focused our analyses on periods of extreme temperature: in summer, between July 1 and September 1, and winter, between November 1 and February 15. With the use of multivariate regression tree analyses, we found cover-site temperatures were influenced largely by tunnel length and subsequently opening width and soil cover. Linear regression models further showed that increasing tunnel length increased temperature stability and dampened seasonal temperature extremes. Climate change models predict increased warming for southwestern North America. Cover sites that buffer temperature extremes and fluctuations will become increasingly important for survival of tortoises. In planning future translocation projects and conservation efforts, decision makers should consider habitats with terrain and underlying substrate that sustain cover sites with long tunnels and expanded openings for tortoises living under temperature extremes similar to those described here or as projected in the future.

    INTRODUCTION In 1996-1998 the U.S. Geological Survey (USGS) conducted a geochemical study of the Bureau of Land Management's (BLM) 5.5 million-acre Northern and Eastern Colorado Desert Resource Area (usually referred to as the NECD in this report), Imperial, Riverside, and San Bernardino Counties, southeastern California (figure 1). This study was done in support of the BLM's Coordinated Management Plan for the area. This report presents analytical data from this study. To provide comprehensive coverage of the NECD, we compiled and examined all available geochemical data, in digital form, from previous studies in the area, and made sample-site plots to aid in determining where sample-site coverage and analyses were sufficient, which samples should be re-analyzed, and where additional sampling was needed. Previous investigations conducted in parts of the current study area included the National Uranium Resource Evaluation (NURE) program studies of the Needles and Salton Sea 1? x 2? quadrangles; USGS studies of 12 BLM Wilderness Study Areas (WSAs) (Big Maria Mountains, Chemehuevi Mountains, Chuckwalla Mountains, Coxcomb Mountains, Mecca Hills, Orocopia Mountains, Palen-McCoy, Picacho Peak, Riverside Mountains, Sheephole Valley (also known as Sheep Hole/Cadiz), Turtle Mountains, and Whipple Mountains); and USGS studies in the Needles and El Centro 1? x 2? quadrangles done during the early 1990s as part of a project to identify the regional geochemistry of southern California. Areas where we did new sampling of rocks and stream sediments are mainly in the Chocolate Mountain Aerial Gunnery Range and in Joshua Tree National Park, which extends into the west-central part of the NECD, as shown in figure 1 and figure 2. This report contains analytical data for 132 rock samples and 1,245 stream-sediment samples collected by the USGS, and 362 stream-sediment samples and 189 soil samples collected during the NURE program. All samples are from the Northern and Eastern Colorado

    Groundwater quality in the approximately 963-square-mile Borrego Valley, Central Desert, and Low-Use Basins of the Mojave and Sonoran Deserts study unit was investigated as part of the Priority Basin Project of the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The study unit is located in southern California in San Bernardino, Riverside, San Diego, and Imperial Counties. The GAMA Priority Basin Project is being conducted by the California State Water Resources Control Board in collaboration with the U.S. Geological Survey and the Lawrence Livermore National Laboratory. The GAMA Borrego Valley, Central Desert, and Low-Use Basins of the Mojave and Sonoran Deserts study was designed to provide a spatially unbiased assessment of the quality of untreated (raw) groundwater in the primary aquifer system. The assessment is based on water-quality and ancillary data collected by the U.S. Geological Survey from 52 wells (49 grid wells and 3 understanding wells) and on water-quality data from the California Department of Public Health database. The primary aquifer system was defined by the depth intervals of the wells listed in the California Department of Public Health database for the Borrego Valley, Central Desert, and Low-Use Basins of the Mojave and Sonoran Deserts study unit. The quality of groundwater in the primary aquifer system may be different from that in the shallower or deeper water-bearing zones; shallow groundwater may be more vulnerable to surficial contamination. This study assesses the status of the current quality of the groundwater resource by using data from samples analyzed for volatile organic compounds (VOCs), pesticides, and naturally occurring inorganic constituents, such as major ions and trace elements. This status assessment is intended to characterize the quality of groundwater resources in the primary aquifer system of the Borrego Valley, Central Desert, and Low-Use Basins of the Mojave and Sonoran Deserts study unit, not the

    2008-01-01

    Published geologic information from the central and eastern United States identifies 83 faults, groups of sand blows, named seismic zones, and other geological features as known or suspected products of Quaternary tectonic faulting. About one fifth of the features are known to contain faulted Quaternary materials or seismically induced liquefaction phenomena, but the origin and associated seismic hazard of most of the other features remain uncertain. Most of the features are in or near large urban areas. The largest cluster of features is in the Boston-Washington urban corridor (2005 estimated population: 50 million). The proximity of most features to populous areas identifies paleoseismic targets with potential to impact urban-hazard estimates.

    During the last 20 years, there has been a significant growth in the training of overseas students especially within the European Union. Informal discussions with past and present students revealed a marked reluctance to take part in interviews about the nature of "English Parallel" courses. Alternative sources of information include blogs and commentaries written on the internet by present and former students at these schools. Such blogs are relatively limited in number and of variable length. They have been written for a variety of reasons and range in content from commentaries on training to wider discussion of life in Central and Eastern Europe. Six blogs were identified from an internet search, and a qualitative approach was adopted for the analysis of text content. Their experience is assessed, and potential approaches to greater integration of training across Europe are considered.

    Full Text Available The paper analyzes the phenomenon of income inequality in ten countries from Eastern and Central Europe (ECE, by highlighting two aspects: (1 the link between growth and income inequality; (2 the effects of trade openess and other key factors on income inequality, such as: foreign direct investment (FDI, market capitalization and educational level of labour force. The method used was the Panel Data Analysis with statistical data from the period of 2000-2014. An increasing effect in income inequality was identified due to the trade openess, the inward stock of ISD and the market capitalization and an equalizing effect in the income distribution generated by the educational level of labour force. A positive association was also found between the growth of PIB per capita level and the increase of income inequality in the examined countries.

  14. A PVAR MODEL BUILT ON THE RICARDIAN APPROACH TO DEFICITS IN CENTRAL AND EASTERN EUROPE

    Full Text Available In the current times, the issue of the deficits became very problematic for the economists, as well as for the practitioners and theoreticians. The purpose of this paper consists in the construction of a Panel VAR model, which has the role to test the Ricardian approach to deficits in several countries from Central and Eastern Europe. The analyzed countries are Austria, Czech Republic, Hungary, Bulgaria, Romania and Ukraine and the time interval starts in 1998 and it ends in 2013.  The used variables are the gross national saving rate and the budget balance for each of the six countries. Our results show that in this geographical-economical area, the Ricardian approach to deficits does not hold as a valid macroeconomic theory.

    2016-03-01

    Climate change effects are expected to be more severe for some segments of society than others. In Mexico, climate variability associated with climate change has important socio-economic and environmental impacts. From the central mountainous region of eastern Veracruz, Mexico, we analyzed data of total annual precipitation and mean annual temperature from 26 meteorological stations (1922-2008) and from General Circulation Models. We developed climate change scenarios based on the observed trends with projections to 2025, 2050, 2075, and 2100, finding considerable local climate changes with reductions in precipitation of over 700 mm and increases in temperature of ~9°C for the year 2100. Deforested areas located at windward were considered more vulnerable, representing potential risk for natural environments, local communities, and the main crops cultivated (sugarcane, coffee, and corn). Socio-economic vulnerability is exacerbated in areas where temperature increases and precipitation decreases.

    Full Text Available Our paper investigates the extent of capital market co-movements between three emerging markets Czech Republic, Hungary and Poland and three developed markets from the European Union – Austria, France and Germany. We test whether an increase in correlations between the six markets took place in recent years, as revealing higher integration of capital markets in the region. We find a statistically significant positive trend in cross-market correlations between 1999 and 2008, before the emergence of the global financial crisis. Movements in national stock markets are not fully synchronized, but increases in market volatilities lead to increases in cross-country correlations. There is a long-term relationship between some of these countries capital markets, and information is transmitted from one market to the other. Our findings confirm previous studies and lead to the conclusion that stock markets from Central and Eastern Europe became more integrated with the developed markets in European Union.

    2014-03-01

    Full Text Available This paper analyses the determinants of the changes in the non-performing loan (NPL ratio in selected European emerging markets. The model was estimated on a panel dataset using a fixed effects estimator for seven Central and Eastern European (CEE countries between Q3:2007 and Q3:2012. The countries analyzed are Bulgaria, Croatia, Czech Republic, Hungary, Latvia, Romania and Slovakia. Although the literature on NPLs is quite extensive, this is the first empirical research on the countries of CEE region using aggregate, country-level data on problem loans. The results suggest that the primary cause of high levels of NPLs is the economic slowdown, which is evident from statistically significant and economically large coefficients on GDP, unemployment and the inflation rate.

  19. Effective Exchange Rates in Central and Eastern European Countries: Cyclicality and Relationship with Macroeconomic Fundamentals

    Directory of Open Access Journals (Sweden)

    Stavárek Daniel

    2015-06-01

    Full Text Available This paper examines the evolution of effective exchange rates in nine Central and Eastern European countries in terms of development trends, volatility and cyclicality. Consequently, it provides direct empirical evidence on the nature of the relationship between effective exchange rates and selected macroeconomic fundamentals, addressing a key precondition of numerous exchange rate determination models and theories that attempt to explain the role of exchange rates in the economy. The results suggest that flexible exchange rate arrangements are reflected in both nominal and real effective exchange rates having higher volatility and variability. Furthermore, the results provide mixed evidence in terms of intensity, direction and cyclicality, but show a weak correlation between exchange rates and fundamentals. Sufficiently high coefficients are found only for money supply. Consequently, using fundamentals for the determination of exchange rates and using the exchange rate to explain economic development may be of limited use for the countries analyzed.

  1. Educational Systems and Inequalities in Educational Attainment in Central and Eastern European Countries

    Directory of Open Access Journals (Sweden)

    Irena Kogan

    2012-06-01

    Full Text Available Before exploring the selectivity of educational attainment in detail, this article extensively describes the contours of educational systems in Central and Eastern European (CEE countries. These countries provide an interesting setting in view of their post-secondary education expansion and differentiation, as well as their variation in the degree of vocational orientation at the secondary level. Drawing on high quality, national micro data, we find that students from disadvantaged family backgrounds who manage to enter post-secondary education are ʽdivertedʼ to second-tier post-secondary institutions, while long-term university programs are more likely to be dominated by students whose parents have an academic background. At the secondary level, we confirm the patterns of negative selection among students from lower social backgrounds into lower vocational programs. This diversion effect at the secondary level is especially pronounced in CEE countries that inherited a strong secondary vocational system and reinstalled early tracking.

  2. Compulsory Purchase in the Transitional Countries of Central and Eastern Europe

    Directory of Open Access Journals (Sweden)

    Richard Grover

    2008-04-01

    Full Text Available Until the ending of Communist rule in Central and Eastern Europe, the objective of compulsory purchase was the achievement of a socialist society in which the ownership of the means of production, including land, was to be collective rather than private. Compulsory purchase legislation and laws on ownership were used to expropriate private property. After 1990 the newly elected democratic governments changed the constitutions to permit and protect private ownership of land. However, compulsory purchase is essential in a market economy to deal with certain aspects of market failure. These include the need to facilitate the provision of collective goods, such as infrastructure and utility networks, and regeneration where the state may need to disrupt a prisoners’ dilemma situation. In spite of their commitment to the inviolability of private property, the transitional economies have had to develop compulsory purchase procedures and means of assessing compensation.

    2013-01-01

    This paper presents the results of a systematic review of literature on the psychosocial wellbeing of populations in Central and Eastern Europe during the transition period subsequent to the fall of the SovietBloc. A revision of research addressing emotional wellbeing trends in this period and theoretical models was carried in order to verify their validity in the analysis of empirical studies. Hence, a systematic bibliographic review was conducted, aiming to find possible subjective mediators between social variables derived from change sand emotional wellbeing. The results of the review show that subjective mediators such as locus of control,perceived control, self-efficacy beliefs, perceived familial support, and the subjective evaluation of social change explain part of the relationship between macrosocial changes and emotional wellbeing. Results appear coherent with proposed multidimensional models of social change and mental health, although further research should be conducted to determine the specific weight of these phenomena in individual emotional wellbeing.

    1995-12-31

    Heating is a vital energy service in Central and Eastern Europe, but the current delivery mechanisms are riddled with problems. District heating (DH) in its present technical form and with the present management structures is an inefficient system which produces expensive heat. Customers cannot control it and react to overheating by opening windows, even in winter. DH facilities together with other forms of individual heating are responsible for air pollution, causing severe impacts on the health of urban residents. The issues relating to DH are discussed, the first World Bank activities and experiences with projects in Poland are analyzed, and the cornerstones of a strategy to support future World Bank financing and the development of sound heating policies in CEE are presented.

    2015-11-01

    Full Text Available Despite the growing interest in foreign direct investments (FDI, substantial uncertainty still exists regarding what stimulates foreign investors to operate in a foreign market and uneven distribution of FDI across countries. Using panel data for 2001 -2012 period, the major determinants of the FDI inflows into the Central and Eastern European Countries are analysed in this study. Strong evidence are found that while EU CR indices, EU and USA real GDP growth rates and global financial crisis have power to explain FDI inflows among all other push factors, labour cost, electricity price, real exchange rate and host CR indices have strong influential on FDI as the most effective pull factors. However, study fails to find any effect of openness, tax rates on commercial profits, USA CR indices, interest rate differentials and host real GDP growth on FDI.

    Full Text Available This paper aims to investigate stochastic properties of the consumption-income ratios in eleven central and eastern European (CEE countries: Bulgaria, Croatia, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, and Slovenia. The heterogeneous panel unit root tests are used to account for cross-sectional dependence and the Modified Augmented Dickey-Fuller unit root test over the period March 1997-September 2012. The half-lives are also calculated as to find the strong mean-reversion in the consumption income ratio for nine of eleven CEE economies; and the exceptions are Croatia and Slovenia. In other words, empirical findings provide significant support for the existence of hypothesis that the consumption-income ratio is a mean reversion. Accordingly, the policy implications have permanent effects on the consumption of households only in Croatia and Slovenia.

  9. Determinants of banks’ net interest margins in Central and Eastern Europe

    2013-03-01

    Full Text Available This research analyzes the main determinants of the net interest margin of banks operating in Central and Eastern European (CEE countries in the period from 1999 to 2010. The results reveal several main drivers of net interest margins in the CEE. Prior to 2008 the net interest margins declined primarily due to strong capital inflows and stable macroeconomic environment. In the crisis period, significant rise in government debt accompanied by the increase in macroeconomic risks and abating capital inflows were pushing margins up while other factors such as low credit demand, higher capitalization and significantly increased share of non-performing loans pressured banks’ margins down. The results also confirm the important contribution of higher efficiency to lowering banks’ margins.

    The genetic diversity and phylogenetic survey of native sheep breeds in the eastern and southern Central Asia were assessed in the present study. The clustering, principal components, structure and F statistics all demonstrate that the native sheep breeds in these regions be classified into two genetic groups: Mongolia-Tibetan sheep group and South-Southeast Asia sheep group. The Mongolia sheep group and the Tibetan sheep group had a certain degree of gene communication from the ancient times. In the present study we demonstrated that the Chinese native sheep populations belonged to Mongolia-Tibetan sheep group. However, the relationships among the sheep populations in Mongolia sheep group in China were not closely related to the geographical distance among sheep populations.

    2012-03-01

    Full Text Available Projected precipitation changes in Central/Eastern Europe on the basis of ENSEMBLE simulations. For building appropriate local/national adaptation and mitigation strategies, detailed analysis of regional climate change is essential. In order to estimate the climate change for the 21st century, both global and regional models may be used. However, due to the coarse horizontal resolution, global climate models are not appropriate to describe regional scale climate processes. On the other hand, regional climate models (RCMs provide more realistic regional climate scenarios. A wide range of RCM experiments was accomplished in the frame of the ENSEMBLES project funded by the EU FP6 program, which was one of the largest climate change research project ever completed. All the RCM experiments used 25 km horizontal resolution and the A1B emission scenario, according to which CO2 concentration by 2100 is estimated to exceed 700 ppm, i.e., more than twice of the preindustrial level.The 25 km spatial resolution is fine enough to estimate the future hydrology-related conditions in different parts of Europe, from which we separated and analyzed simulated climate data sets for the Central/Eastern European region. Precipitation is an especially important climatological variable because of agricultural aspects and flood-related natural hazards, which may seriously affect all the countries in the evaluated region. On the basis of our results, different RCM simulations generally project drier summers and wetter winters (compared to the recent decades. The southern countries are more likely to suffer more intense warming, especially, in summer, and also, more intense drought events due to the stronger Mediterranean impact.

  12. Health Care Performance and Health Financing Systems in Countries from Central and Eastern Europe

    Sorin Gabriel ANTON

    2012-02-01

    Full Text Available A common feature of all health systems from emerging economies is the shortage of financial resources. This fact is currently exacerbated by the economic crisis that has led many governments to reconsider the level of public spending in the health sector. Starting from the Romanian experience, the paper aims to highlight the linkage between the performance of the health system and the total health spending for selected countries from Central and Eastern Europe. Romania has the lowest level of health expenditure as percentage of GDP in Europe, even if its growth rate for 2003-2008 was the highest. In addition, empirical evidence shows that these resources are used inefficiently. Despite the increasing resources allocated to the health sector, statistical analysis shows that health system efficiency, as measured by under-5 (child mortality rate, is still low. We use regression analysis based on crosssection data in order to explain the differences in health expenditure and their implication on the system efficiency. Health data have been provided by international organizations. Crosssection regression results suggest that totalhealth spending and GDP per capita are the most important factors explaining differences in health status across Central and Eastern European countries, though other lifestyle factors could play important roles.

    Full Text Available The last two decades have seen the adoption of laws on non-territorial autonomy (NTA by several states in Central and Eastern Europe (CEE, as well as debates on the applicability of this concept to other countries of the region. This development has in turn elicited a growing interest from international organisations in the potential of NTA as a modality of minority rights provision in the New Europe. In spite of this interest, relatively little is known about the practical implementation of NTA within this setting and its reception by ethnonational minorities and majorities alike. This article offers a preliminary comparative analysis of debates and practices around NTA in four countries-Hungary, Romania, Estonia and Russia-and seeks to link these cases to broader Central and East European-focused debates on state and nation-building, democratisation and participation in public life. By way of conclusion, it makes a case for further research on NTA 'from the ground up', focusing more squarely on the everyday practice of autonomy from a minority perspective and how this might inform and deepen understandings of minority agency within current processes of political community building in CEE and-ultimately-beyond.

    Full Text Available Cross-border acquisitions play an important role in the corporate strategic development and international expansion. The paper summarizes the results of the dissertation, which intends to establish vital link between research and practice, deeply exploring the risk assessment methods and the scope of due diligence audit in the pre-acquisition phase. The central hypothesis of the comprehensive model stated that thorough due diligence in the pre-acquisition phase is necessary to make successful cross-border acquisition. The empirical evidence has been drawn on data sample of acquisitions made by automotive firms in cross-border acquisitions in the Central and Eastern Europe. The main results support the proposition that the thorough due diligence audit is necessary pre-requisite for successful acquisition. The findings further support the clear trend: In the past few years, several big automotive leaders strategically gain more control over their supply chains by acquiring technology specialists. From a practical standpoint, the research results provide acquisition management with a simple method of performing the pre-acquisition evaluation of potential acquisition candidates.

  19. Holocene mammalian change in the central Columbia Basin of eastern Washington state, USA

    Predictions of changes in the Holocene mammalian fauna of the central Columbia Basin in eastern Washington (USA) based on environmental changes are largely met. Taxonomic richness is greatest during periods of cool-moist climate. Rates of input of faunal remains to the paleozoological record may suggest greater mammalian biomass during periods of greater moisture but are difficult to interpret without data on sampling intensity in the form of volume of sediment excavated. Abundances of leporids and grazing ungulates fluctuate in concert with abundance of grass. Several biogeographic records are tantalizing but require additional study and data before being accepted as valid. Records of red fox (Vulpes vulpes) indicate this species was present in the central basin during the Holocene contrary to historic records and recent suggestions modern foxes there are escapees from fur farms. Bison (Bison bison) and bighorn sheep (Ovis canadensis) underwent diminution of body size during the Holocene. Modern efforts to conserve the Columbia Basin ecosystem are advised to consider the Holocene record as indicative of what may happen to that ecosystem in the future.

    This study aims to provide the depositional facies, sequence stratigraphic and paleoclimatic characteristics of the Mid-Eocene (Bartonian) continental succession exposed at Gebel El-Goza El-Hamra (Shabrawet Area, NE Eastern Desert, Egypt). The studied succession consists of siliciclastic rocks followed upward by carbonate rocks. Detailed field observation and petrographic investigation indicate accumulation in floodplain-dominated alluvial and shallow lacustrine systems. The floodplain-dominated alluvial facies (45 m thick) is composed mainly of carbonate nodules-bearing, mottled mudrock with subordinate sandstone and conglomerate beds. The conglomerate and pebbly sandstone bodies interpreted as ephemeral braided channel deposits. The massive, laminated, planner cross-bedded, fine- to medium-grained sandstone bodies interlayered within mudstone reflect sheet flood deposits. The mudrocks associated with paleosols represent distal floodplain deposits. The shallow lacustrine facies (15 m thick) is made up of an alternation of marlstone, micritic limestone, dolostone and mudrock beds with charophytes and small gastropods. Both the alluvial and lacustrine facies show evidence of macro-and micro-pedogenic features. Pollen assemblages, stable δ18O and δ13C isotopes, and paleopedogenic features reflect prevalence of arid to semi-arid climatic conditions during the Bartonian. The sequence stratigraphic framework shows an overall fining-upward depositional sequence, consisting of Low- and High-accommodation Systems Tracts (LAST, HAST), and is bounded by two sequence boundaries (SB-1, SB-2). Conglomerate and pebbly sandstone deposits (braided channel and sheet flood deposits) of the lower part of the alluvial facies reflect a LAST. Mudrock and silty claystone facies (distal floodplain deposits) of the upper part of alluvial facies and its overlying lacustrine facies correspond to a HAST. The LAST, HAST and SB were formed during different accommodation-to-sediment supply (A

    The southeastern sector of the Hafafit Metamorphic Complex, southern Eastern Desert of Egypt comprises infrastructural orthogneisses of tonalite and syenogranite parentage, amphibolites, and a volcano-sedimentary association. These are overthrust by an obducted suprastructural ophiolite nappes via the Nugrus thrust. The protolith of the biotite-hornblende-gneisses was formed during island-arc accretion, while that of the garnet-biotite gneisses were formed in a within-plate regime, consistent with a transition to a post-collisional setting. The volcano-sedimentary association comprises interbedded and intercalated highly foliated metapelitic schists, metabasites, and leucocratic gneisses, deposited in a back-arc basin. The metapelites and the leucocratic gneisses originated from immature Fe-shales and arkoses derived from intermediate-mafic and acidic igneous rocks, respectively, via weak chemical weathering in a tectonically active island arc terrane. The intercalated amphibolites were derived from tholeiitic basalts generated in a back-arc setting. The volcano-sedimentary association was metamorphosed under upper-amphibolite facies conditions with pressures of 9-13 kbar and temperatures of 570-675 °C, as derived from conventional geothermobarometry and pseudosection calculation. A steep, tight clockwise P-T path is constrained and a geothermal gradient around 20 °C/km is estimated for the peak metamorphism. We assume that deformation and metamorphism are due to crustal thickening during the collision of East and West Gondwana, where peak metamorphism took place in the middle to lower crust at 33 km average crustal depth. This was followed by a subsequent quasi-isothermal decompression due to rapid exhumation during wrench tectonics. Sinistral transcurrent shearing with extensional denudation resulted in vertical ductile thinning that was accompanied by heat input from magmatism, as indicated by a higher geothermal gradient during retrograde metamorphism and

    The western part of the Iberian Peninsula (Iberian Massif) is the best exposed fragment of the Variscan orogen in Europe. Its southern half was generated by an oblique collision between three continental terranes belonging to the margins of Laurassia (Avalonia) - the South Portuguese Zone- and Godwana - the Ossa Morena Zone (OMZ) and the Central Iberian Zone (CIZ). The boundaries between them are considered to be sutures. A 210 km long magnetotelluric profile across the eastern part of the Central Iberian Zone is presented. The profile crosses the boundary between the Ossa Morena and Central Iberian zones and spans up to the Tajo basin, crossing the Sierra de Alcudia and the Toledo Mountains. The main structures investigated are: the Los Pedroches batholit, the Alcudia anticline - Domo Extremeño, the Almadén syncline, the fold structures located to the north and the Toledo fault. We present the results of this profile, which consists of 33 MT sites, with the five components of the electromagnetic field and period ranging from 1000 Hz to 1000 s. In each MT site a TEM sounding was carried out in order to characterize the shallow electrical resistivity and to control the galvanic distortion (static shift). The results of two-dimensional inversion reveal a high conductivity zone with the transition OMZ/CIZ. Apart from the sallow structure, the most striking feature is a high conductive layer at middle to lower crust in the whole CIZ, confirming the prolongation of the same layer detected in the OMZ in previous studies.

Being in contact with Josef C Brada, Professor Emeritus, Editor of the journal Eastern European Economics (EEE, we realized that the paper had been sent to both journals, although first published in the EEE and then in our Journal. According to professor Brada’s and our analysis, the paper published in these two journals is exactly the same, except for minor differences in wording, most likely due to editing the text before publication. The outstanding differences are in the title and the fact that the paper published in our Journal has three authors and in EEE journal has two. Whatsoever, owing to the fact that the article had been sent to both journals almost at the same time, it had been impossible to find out the case during the review procedure.

    Central-eastern Trans-Mexican Volcanic Belt (TMVB) is featured by large basins (i.e., Toluca, Mexico, Puebla-Tlaxcala, Libres-Oriental). It has been supposed that major crustal faults limit these basins. Sierra de Las Cruces range separates the Toluca and Mexico basins. The Sierra Nevada range separates Mexico basin from the Puebla-Tlaxcala basin. Based in gravity and seismic data we inferred the Toluca basin is constituted by the Ixtlahuaca sub-basin, to the north, and the Toluca sub-basin to the south, which are separated by a relative structural high. The Toluca depression is more symmetric and bounded by sub-vertical faults. In particular its eastern master fault controlled the emplacement of Sierra de Las Cruces range. Easternmost Acambay graben constitutes the northern and deepest part of the Ixtlahuaca depression. The Toluca-Ixtlahuaca basin is inside the Taxco-San Miguel de Allende fault system, and limited to the west by the Guerrero terrane which continues beneath the TMVB up to the Acambay graben. Mexico basin basement occupies an intermediate position and featured by a relative structural high to the north-east, as established by previous studies. This relative structural high is limited to the west by the north-south Mixhuca trough, while to the south it is bounded by the east-west Copilco-Xochimilco-Chalco sub-basin. The Puebla-Tlaxcala basin basement is the shallowest of these 3 tectonic depressions. In general, features (i.e., depth) and relationship between these basins, from west to east, are controlled by the regional behavior of the Sierra Madre Oriental fold and thrust belt basement (i.e., Oaxaca Complex?). This study indicates that an active east-west regional fault system limits to the south the TMVB (from the Nevado de Toluca volcano through the Popocatepetl volcano and eastward along southern Puebla-Tlaxcala basin). The Tenango and La Pera fault systems constituting the western part of this regional fault system coincide with northern

    The EU-project CECILIA (Central and Eastern Europe Climate Change Impact and VulnerabiLIty Assessment) aims at delivering a climate change impacts and vulnerability assessment in targeted areas of Central and Eastern Europe. This region appears particularly vulnerable with regard to future changes in extremes (Christensen and Christensen 2003, Schär et al. 2004), likely due to regional specificities such as highly varying topography and continentality, and due to changes in soil moisture content (Seneviratne et al. 2006). In the project, emphasis is given to applications of regional climate modeling studies at a resolution of 10 km for local impact studies in key sectors of the region. The project includes the analysis of extreme weather events in present day and future climate in the target region. For this purpose, an extensive list of precipitation and temperature indices was defined. Observational data used for the indices calculation comes from the European Climate Assessment & Dataset project (ECA&D, Klein Tank et al. 2002), from the ENSEMBLES gridded observations (E-Obs, Haylock et al. 2008), and from station data of the local partners in Central and Eastern Europe. Moreover, the same indices were calculated consistently for a selection of pre-existing RCM datasets (PRUDENCE, ENSEMBLES), and for the CECILIA driving models. Later on, the 10 km high-resolution climate simulations from CECILIA will be included in the analysis. Here we focus on the analysis of a selection of temperature indices, and on the validation of the model-derived indices with the observations. Generally, the spatial agreement between the models and the observations is very good for mean, maximum and minimum temperature (both in terms of the spatial variability and the spatial correlation). The spread between the models is larger for the daily temperature range, with most models showing larger spatial variability compared to the observations. When it comes to heat and cold wave indices

    As the USArray Transportable Array entered the central and eastern United States, several Federal agencies (National Science Foundation, U.S. Geological Survey, U.S. Nuclear Regulatory Commission, and Department of Energy) recognized the unique opportunity to retain TA stations beyond the original timeline. The mission of the CEUSN is to produce data that enables researchers and Federal agencies alike to better understand the basic geologic questions, background earthquake rates and distribution, seismic hazard potential, and associated societal risks of this region. The selected long-term sub-array from Transportable Array (TA) stations includes nearly 200 sites, complemented by 100 broadband stations from the existing regional seismic networks to form the Central and Eastern United States Network (CEUSN). Multiple criteria for site selection were weighed by an inter-agency TA Station Selection (TASS) Working Group: seismic noise characteristics, data availability in real time, proximity to nuclear power plants, and homogeneous distribution throughout the region. The Array Network Facility (ANF) started collecting data for CEUSN network stations since late 2013, with all stations collected since May 2014. Regional seismic data streams are collected in real-time from the IRIS Data Management Center (DMC). TA stations selected to be part of CEUSN, retain the broadband sensor to which a 100 sps channel is added, the infrasound and environmental channels, and, at some stations, accelerometers are deployed. The upgraded sites become part of the N4 network for which ANF provides metadata and can issue remote commands to the station equipment. Stations still operated by TA, but planned for CEUSN, are included in the virtual network so all stations are currently available now. By the end of 2015, the remaining TA stations will be upgraded. Data quality control procedures developed for TA stations at ANF and at the DMC are currently performed on N4 data. However

    A new exploration method has been developed by Saunders et al. (Geophysics 58(10) (1993) 1417) using surface and aerial gamma-ray spectral measurements in prospecting for petroleum in stratigraphic and structural traps. Wadi Araba area, North-eastern Desert, Egypt, was selected to apply this method on its recorded aerial gamma-ray spectrometric survey data, due to its distinct stratigraphic and structural setting as well as its situation in close connection with the Gulf of Suez, which represents one of the important sites of oil production in Egypt. The three variables (eU, eTh, and K) registered for the whole study area, in the form of three contour maps, were digitized along the flight paths every 1.0 km. The DRAD arithmetic means plus three standard deviations for the data set were computed. Any single profile value greater than this quantity should have a probability of 99.87% that it represents a valid anomaly and is not caused by random variations in the background values. The use of these criteria has identified one flight line which has a valid anomaly that is not caused by random variations in the background values. This might indicate a prospective possibility for petroleum accumulation in the Wadi Araba area. North-eastern Desert, Egypt.

    Groundwater quality in the 12,103-square-mile Borrego Valley, Central Desert, and Low-Use Basins of the Mojave and Sonoran Deserts (CLUB) study unit was investigated by the U.S. Geological Survey (USGS) from December 2008 to March 2010, as part of the California State Water Resources Control Board (SWRCB) Groundwater Ambient Monitoring and Assessment (GAMA) Program's Priority Basin Project (PBP). The GAMA-PBP was developed in response to the California Groundwater Quality Monitoring Act of 2001 and is being conducted in collaboration with the SWRCB and Lawrence Livermore National Laboratory (LLNL). The CLUB study unit was the twenty-eighth study unit to be sampled as part of the GAMA-PBP. The GAMA CLUB study was designed to provide a spatially unbiased assessment of untreated-groundwater quality in the primary aquifer systems, and to facilitate statistically consistent comparisons of untreated-groundwater quality throughout California. The primary aquifer systems (hereinafter referred to as primary aquifers) are defined as parts of aquifers corresponding to the perforation intervals of wells listed in the California Department of Public Health (CDPH) database for the CLUB study unit. The quality of groundwater in shallow or deep water-bearing zones may differ from the quality of groundwater in the primary aquifers; shallow groundwater may be more vulnerable to surficial contamination. In the CLUB study unit, groundwater samples were collected from 52 wells in 3 study areas (Borrego Valley, Central Desert, and Low-Use Basins of the Mojave and Sonoran Deserts) in San Bernardino, Riverside, Kern, San Diego, and Imperial Counties. Forty-nine of the wells were selected by using a spatially distributed, randomized grid-based method to provide statistical representation of the study unit (grid wells), and three wells were selected to aid in evaluation of water-quality issues (understanding wells). The groundwater samples were analyzed for organic constituents (volatile

    The variability in partial pressure of carbon dioxide (pCO2) and its control by biological and physical processes in the mixed layer (ML) of the central and eastern Arabian Sea during inter-monsoon, northeast monsoon, and southwest monsoon seasons were studied. The ML varied from 80-120 m during NE monsoon, 60-80 m and 20-30 m during SW- and inter-monsoon seasons, respectively, and the variability resulted from different physical processes. Significant seasonal variability was found in pCO2 levels. During SW monsoon, coastal waters contain two contrasting regimes; (a) pCO2 levels of 520-685 atm were observed in the SW coast of India, the highest found so far from this region, driven by intense upwelling and (b) low levels of pCO2 (266 atm) were found associated with monsoonal fresh water influx. It varied in ranges of 416-527 atm and 375-446 atm during inter- and NE monsoon, respectively, in coastal waters with higher values occurring in the north. The central Arabian Sea pCO2 levels were 351-433, 379-475 and 385-432 atm during NE- inter and SW monsoon seasons, respectively. The mixed layer pCO2 relations with temperature, oxygen, chlorophyll and primary production revealed that the former is largely regulated by physical processes during SW- and NE monsoon whereas both physical and biological processes are important in inter-monsoon. Application of Louanchi et al (1996) model revealed that the mixing effect is the dominant during monsoons, however, the biological effect is equally significant during SW monsoon whereas thermodynamics and fluxes influence during inter-monsoons.

    Full Text Available Spring pollinosis has become a part of life for many people throughout the world. A wide range of knowledge about the allergenic potential of individual pollen allergen types is documented well, but the starting point of the pollen allergens expression regulation in plants itself is still not fully answered. Expression analysis of pollen allergens does not yet have any specific protocols or methods developed, despite a very good sequence background available in public bioinformatics databases. However, research in this area of interest has a great application potential for breeding and biotechnology of allergenic plants that may benefit from the knowledge of the expression of allergen coding genes in individual varieties or genotypes. Here, a brief review of up-to-date knowledge about the coding sequences of central and eastern European spring pollen allergens is introduced together with real-time based analysis of the expression of two of the main pollen allergens–PR protein type and profilin type of birch and hazelnut.

    Full Text Available Arnica montana is a species of European Union interest, whose harvest from the wild and exploitation should be made under certain management measures. In Romania it is a vulnerable species due to excessive collection. It is a species with European areal occuring in pastures, meadows, forest glades, shrubs communities of mountain to the subalpine regions and, isolated, up to the alpine belt. Most of the plant communities with Arnica montana are semi-natural, with a floristic composition in which there are numerous rare or threatened species also supporting the need of their conservation. Our study was focused on a numerical classification (hierarchical, using Flexible ß algorithm and Bray-Curtis dissimilarity based on 48 plots, of the plant communities with Arnica montana from the central region of Romanian Eastern Carpathians and on the investigation of the effect of some environmental variables (Ellenberg indicator values, altitude, heat load index on their floristic composition (100 m2 scale. Vegetation – environment relationship was assessed via detrended correspondence analysis and canonical correspondence analysis with Monte Carlo test. Six plant communities with Arnica montana were identified (communities of Festuca rubra with Agrostis capillaris, Festuca nigrescens, Vaccinium myrtillus, Nardus stricta, Vaccinium gaultherioides and Juniperus sibirica with a floristic composition mainly shaped by altitude, temperature and soil nitrogen content. Details related to location and sites characteristics, diagnostic species, floristic composition, presence of other rare or threatened species and Arnica montana abundance were presented for all these plant communities.

    2013-06-01

    Full Text Available In 2008 the global financial and economic crisis ended a six-year-long boom period with an average growth rate well above 5% in Central and Eastern Europe (CEE. Although not the originators of the crisis some CEE countries such as the Baltic States and Ukraine were among the worst hit by this economic downturn. The crisis did not only shatter the financial markets, banks and the real economy but also the growth image of CEE. The huge market potential and expected higher growth rates resulting from the catching-up process to West European standards have been the main reason for the flood of foreign direct investments into the countries of the region in the two decades before. Suddenly, foreign direct investors were confronted with stalled and even collapsing market growth, shrinking disposable household income, business customers and partners on the verge of bankruptcy and no real sign of a quick recovery. While the situation improved a little in 2011, the economic outlook and the sentiment of foreign investors have remained gloomy, at least for parts of the region. It is obvious that when faced with such a huge economic downturn companies stop geographic expansion and put the brakes on investments.

    Full Text Available This paper provides the overview of competitiveness measures applied in measuring competitiveness of livestock production in Central and Eastern European (CEE countries. Three concepts of competitiveness are presented that are based on (i Porter’s diamond of competitive advantage, (ii competitiveness measures based on accountancy data and Policy Analysis Matrix (PAM approach, and (iii competitiveness measures based on international trade data. On the basis of the presented results the paper evaluates competitiveness of livestock production in CEE countries focusing on policy implications of transition and integration of CEE’s countries livestock sectors into the Single European Market. Low international competitiveness In CEE countries is for beef and milk, but with some indices of most recent improvements. Pork production (e.g. in Bulgaria and sheep production (e.g. in Slovakia may become internationally competitive. Less clear pattern is for the poultry sector. Some improvements may arise as result of a deep restructuring, quality, technology and efficiency improvements and rationalisation of costs, including in food processing.

    2004-12-15

    This paper discusses an approach to determine future biomass production potentials and cost supply curves based on a bottom-up approach. The approach uses detailed data on NUTS3 level (the nomenclature of territorial units for statistics (NUTS) provides a single, uniform breakdown of the economic territory of the European Union). The NUTS is the territorial classification for the compilation of regional accounts for Central and Eastern European Countries and results in biomass supply curves for different scenario conditions that could occur in a European setting. A first assessment of the Ukraine reveals that even with modest assumptions, the Ukrainian agricultural sector could supply 2,000 to 3,000 PJ of primary biomass per year on medium term (i.e. 2010-2015). Cost levels of liquid fuels produced from biomass (such as methanol or Fischer-Tropsch diesel) could end up around 6 Euro/GJ, which is about competitive with production costs of diesel and gasoline from mineral oil. Given the growing demand for biofuels in particular in the EU, biofuels could prove an extremely valuable export commodity for the Ukraine on shorter term already.

    2012-08-01

    Full Text Available Geomorphological theories for long-term relief evolution postulate the existence of planation surfaces, created by the continuouswork of erosion/deposition during periods of tectonic quiescence and recognized as extensive areas of very gentlerelief disturbed only locally by residual elevations, or by the apparent leveling of summit heights in a given region. Afterdecades since the publication of the main theories on landform evolution, the validity of these models is still an open discussion.In this paper, we present studies about the compartmentalization of landform elements, on a regional-scale basis,of central-eastern Brazil. The methods involved Digital Terrain Analysis in Geographic Information Systems, aiming theextraction and characterization of topographic variables and the compilation and mathematical analysis of geophysical andthermochronological data. Results were interpreted according to the geological context and the theories for long-term reliefevolution. The integration of morphometric, thermochronological and geophysical data does not support the validity of usingplanation surfaces in regional stratigraphic correlations.

    Tropospheric ozone (O3) is a trace gas playing important roles in atmospheric chemistry, air quality and climate change. In contrast to North America and Europe, long-term measurements of surface O3 are very limited in China. We compile available O3 observations at Mt. Tai - the highest mountain over the North China Plain - during 2003-2015 and analyze the decadal change of O3 and its sources. A linear regression analysis shows that summertime O3 measured at Mt. Tai has increased significantly by 1.7 ppbv yr-1 for June and 2.1 ppbv yr-1 for the July-August average. The observed increase is supported by a global chemistry-climate model hindcast (GFDL-AM3) with O3 precursor emissions varying from year to year over 1980-2014. Analysis of satellite data indicates that the O3 increase was mainly due to the increased emissions of O3 precursors, in particular volatile organic compounds (VOCs). An important finding is that the emissions of nitrogen oxides (NOx) have diminished since 2011, but the increase of VOCs appears to have enhanced the ozone production efficiency and contributed to the observed O3 increase in central eastern China. We present evidence that controlling NOx alone, in the absence of VOC controls, is not sufficient to reduce regional O3 levels in North China in a short period.

    Full Text Available The European transport strategy promotes the role of railways and expects that the key role in passenger transport should be played by high-speed rail (HSR. Although the core network of high-speed lines has already been built and is operating in Western Europe, there has been little coverage so far in Central and Eastern Europe (CEE. The aim of the conference “High-Speed Rail for CEE Countries” that took place in Prague in June 2016 was to put together academics, policy-makers, and practitioners interested in HSR and to formulate recommendations for CEE countries based on West European countries’ experience. Based on the conference presentations and subsequent discussion, the following conclusions were formulated. Firstly, there are many crucial differences in national HSR build-up and operation, which means that former experience of Western Europe is not directly applicable to CEE countries. Secondly, in comparing presentations discussing experiences in France, Britain, Italy, and Germany, it was concluded that the German approach-upgrading existing lines where possible and only building new lines for bottleneck sections-was the most likely appropriate solution in CEE. Lastly, CEE has the additional problem of many border crossings, with a reduction of traffic in comparison with purely domestic routes, and this effect has to be taken into account.

  18. Welfare State Development in Central and Eastern Europe: A State of the Art Literature Review

    2012-11-01

    Full Text Available The welfare states in Central and Eastern Europe (CEE have undergone massive changes since the beginning of the 1990s. This paper reviews the literature on welfare state development in CEE in light of the theories that have been used to study advanced capitalist democracies. Its purpose is to critically assess the extent to which different theories can explain changes in the welfare state during and after transition. It argues that until now two strands of literature have crystallised: institutionalism and actor-centred explanations. Institutionalists agree that welfare reforms are limited by the path dependence of the national welfare state structures though this framework is biased towards explaining stability. Recent literature seeks to overcome this bias by adding variables that traditionally belong to the actor-centred paradigm. This essay will argue that the gains from such an approach are exceeded by losses in the accuracy and parsimony of explanations. Further, in the actor-centred camp the welfare state is seen as a product of bargaining between various national and international actors. Yet the debate about who is responsible for the present welfare state arrangements is far from over. Unanswered questions revolve around the impact of political parties and ideologies on welfare reforms, the role of bureaucracies, the efficiency of international financial institutions in advocating retrenchment and the precise mechanisms through which all the above actors defend their interests.

    Full Text Available Agriculture posed considerable tensions for the processes of enlargement of the European Union, because of its continuing importance both in the economies of the applicant countries of Central and Eastern European countries which have joined EU on the 1st may 2004., and in the EU budget and acquits communautaire. The preparation of agriculture in the candidate countries to join the EU was rendered more complex by the fact that the Community's Common Agricultural Policy was a moving target. The aim of this paper is to show the bases elements of the Common Agricultural Policy, but also to provide a survey of recent developments relating to agriculture in the EU and new member states of the EU before their accession to EU and their preparation to access on the enlarged market, in order to indicate the main challenges and difficulties posed by enlargement. It seems likely that agricultural policy in the enlarged EU will attach increased priority to objectives such as rural development and the environment. However, these new priorities may be expensive to realize, and may impose a growing burden on the national budgets of EU member states.

    Full Text Available Polybrominated diphenyl ethers (PBDEs levels in environmental media have increased over the last 20-25 years in the world. In aquatic environments PBDEs were found to be accumulated along food chain and Endocrine disruptors toxicity. In this study PBDEs were investigated in sediment and fish tissues from Lake Chaohu in central eastern China. There were 10 PBDEs congeners detected out of all 41 PBDEs. BDE-47 was of the highest with 5.17 ng/g in sediment and 58.47 ng/g in fish. PBDEs were evenly distributed across the surface sediment in the whole lake. It implied that the main source of PBDEs may not be an inflow river like Nanfei. Tissue distribution patterns of PBDEs in four fish species were in the order of BDE-47 > BDE-99 > BDE-100 > BDE-66 > BDE-138 > BDE-183 > BDE-154 > BDE-153. Octa- and deca-BDEs were below the detection limit. The concentrations of all PBDE congeners were higher in gills, livers, and kidneys than those in muscles and adipose tissue. Furthermore, PBDEs in different tissues had some different distribution patterns with fish size. Those discrepancies appeared to be correlated with the PBDEs pollution fluxes varying with the change of the year and their metabolism divergences in fish tissues.

  1. Analysis of Fertility in Ten Central And Eastern European Countries After 1989

    Full Text Available The establishment of democracy in the communist countries, which generated profound social and economic transformation, was accompanied by a decline in fertility. We attempt to provide an overall survey on fertility since 1989 in ten Central and Eastern European Countries, members of the European Union, and to identify the variables which explain the fertility decline. We will use univariate and multivariate statistical analysis to identify disparities between the ten countries, and the variables which explain these differences. Also, we developed a panel econometric model to confirm the hypothesis of a similar pattern of evolution for fertility in these countries and that the decline in fertility can be explained both through demographic and economic variables. The decline in fertility can be explained by economic growth, marriage, divorce, abortion, and migration. The empirical evidence presented in this paper supports the view that the decline in fertility over the 1989s represents the continuation of a longstanding trend of the previous period, according to the demographic transition theory, but its speed and magnitude has been influenced by the new social and economic landscape. These results can be useful for public authorities of the CEE countries to rethinking demographic policies and to ensure the sustainability of demographic growth.

    Full Text Available After 1990, the Central and Eastern European (CEE countries lowered the barriers to FDIs. Of course, many other developments were taking place at the same time: increasing openness to trade, privatization of previously government-owned production, and many other changes as these countries moved in various degrees from socialist to market economies and democratic governments. They privatized many state-owned enterprises, signed foreign trade agreements with other countries in the region, and have generally achieved a significant level of macroeconomic stability with improved growth rates. They also experienced a significant increase in FDI. As a consequence, the ratio of inward FDI to the CEE countries studied here in total world FDI inflows increased more than three-fold. Over the same period, these countries also achieved a substantial increase in their exports, especially towards Western Europe. We present in this paper the relation between the FDIs and exports in the CEE countries during 1990-2010 using statistic data analysis and literature review and underline the factors that determined an increase of exports in these countries. Despite other CEE countries that succeeded to attract many export-oriented FDIs, Romanian case is different because of many local specific factors such as an insufficient local production and a tight fiscal policy.

    Full Text Available The aim of this paper is to quantify the long run and short run relationship between debt and economic activity in Central, Eastern and Southeastern European countries. In order to investigate the impact of public debt on economic growth, the paper uses pooled mean group estimator (PMG for the period between 2000 and 2011. A battery of panel unit root as well as panel cointegration tests is used prior to performing the dynamic panel analysis based on PMG estimator. According to the empirical results, in the long-run debt significantly influences the GDP growth having a negative sign as expected and pointing out that government gross debt lowers the GDP growth. In the short run, debt has statistically significant negative influence on the GDP growth as well, controlling for other determinants of growth (trade openness, total investment and industry value added. Designing policy frameworks that encourage export, promote industrial development and create better environment for long-term investment should foster sustainable growth. Therefore, we find that a credible fiscal consolidation strategy is needed combined with policies to promote lasting growth in order to reach debt-stabilizing levels.

    Full Text Available Abstract Objective To analyze the prevalence of diagnosed and suspected autoinflammatory diseases in Eastern and Central European (ECE countries, with a particular interest on the diagnostic facilities in these countries. Methods Two different strategies were used to collect data on patients with periodic fever syndromes from ECE countries- the Eurofever survey and collection of data with the structured questionnaire. Results Data from 35 centers in 14 ECE countries were collected. All together there were 11 patients reported with genetically confirmed familial Mediterranean fever (FMF, 14 with mevalonate-kinase deficiency (MKD, 11 with tumor necrosis factor receptor associated periodic syndrome (TRAPS and 4 with chronic infantile neurological cutaneous and articular syndrome (CINCA. Significantly higher numbers were reported for suspected cases which were not genetically tested. All together there were 49 suspected FMF patients reported, 24 MKD, 16 TRAPS, 7 CINCA and 2 suspected Muckle-Wells syndrome (MWS patients. Conclusions The number of genetically confirmed patients with periodic fever syndromes in ECE countries is very low. In order to identify more patients in the future, it is important to organize educational programs for increasing the knowledge on these diseases and to establish a network for genetic testing of periodic fever syndromes in ECE countries.

    Phytolith and pollen preserved in the Taipusi Banner paleosol profile, central eastern Inner Mongolia, provide evidence of Holocene grassland vegetation, climate and human impact. The combined phytolith and pollen records reveal a major change in vegetation composition about 5000 a BP. Before 5000 a BP, the vegetation was dominated by Aneurolepidium chinese-Stipa grandis grassland of C4 grasses. After 5000 a BP, C4 grasses rapidly retreated,indicating a shift to colder and more arid conditions. The gradual invasion of Stipa krylovii, Agropyron desertorum, Ephedra, Chenopodiaceae and Caragana reveal the onset of grassland degeneration. Between 10000 and 8720 a BP, the Aneurolepidium chinese-Stipa grandis grassland included a small proportion of Artemisia shrub and Echionopos type plants, implying a strong winter monsoon and very weak summer monsoon. From 8720 to 7000 a BP, C4 grasses were common, indicating a strengthening of the summer monsoon. Between 7000 and 5000 a BP,the Holocene thermal maximum was evident, with a significant expansion of C4 grasses and the presence of some trees (such as Pinus and Betula, and so on) in or near the study site. From 4200-3000 a BP, a sandy grassland of Artemisia and Agropyron desertorum together with As ter-type taxa occurred. Precipitation amelioration took place between 3000 and 2170 a BP, with a rapid development of Echinops type plants and a small expansion of C4 grasses. From 2170 a BP to present, human activities accelerated the process of grassland degeneration.

    The Wata carbonate platform in central and eastern Sinai show a clear pattern of evolutionary development during sedimentation. Three facies are recognized in the carbonate platform. Inner-platform in the south, inter-platform basin in the middle, and outer-platform in the northwest. Such classification was probably performed by the effect of Syrian Arc System that culminated during Turonian in Sinai. Inner-platform includes fining-upward cycles, each begins with packstone, followed by wackestone and capped by lime-mudstone or claystone or molluscan bioclastic wackestone at the base capped by sandy oolitic packstone or dolostone. The dominant faunal associations are molluscs, and echinoids. Inter-platform basin occurs north of inner-platform and extends northwest-southeast direction and comprises fining-upward cycles, each of which begins with bioclastic ostracodal packstone, calcisphere packstone, bioclastic packstone, capped by wackestone and lime-mudstone The faunal association includes, sponge spines, ostracodes, molluscan debris and calcispheres. They were deposited in shoal marine and barrier. The outer-platform occurs at Gebel Giddi and extended northwestwards. The lithofacies are entirely represented by calcisphere wackestone/packstone, with a reduced thickness of 20 m.

    The ongoing global financial crisis, which began in 2007, has drawn attention to the effect of declining economic conditions on public health. A quantitative analysis of previous events can offer insights into the potential health effects of economic decline. In the early 1990s, widespread recession across Central and Eastern Europe accompanied the collapse of the Soviet Union. At the same time, despite previously falling tuberculosis (TB) incidence in most countries, there was an upsurge of TB cases and deaths throughout the region. Here, we study the quantitative relationship between the lost economic productivity and excess TB cases and mortality. We use the data of the World Health Organization for TB notifications and deaths from 1980 to 2006, and World Bank data for gross domestic product. Comparing 15 countries for which sufficient data exist, we find strong linear associations between the lost economic productivity over the period of recession for each country and excess numbers of TB cases (r(2) = 0.94, p < 0.001) and deaths (r(2) = 0.94, p < 0.001) over the same period. If TB epidemiology and control are linked to economies in 2009 as they were in 1991 then the Baltic states, particularly Latvia, are now vulnerable to another upturn in TB cases and deaths. These projections are in accordance with emerging data on drug consumption, which indicate that these countries have undergone the greatest reductions since the beginning of 2008. We recommend close surveillance and monitoring during the current recession, especially in the Baltic states.

  8. Ground Motion Prediction Equations for the Central and Eastern United States

    Seber, D.; Graizer, V.

    2015-12-01

    New ground motion prediction equations (GMPE) G15 model for the Central and Eastern United States (CEUS) is presented. It is based on the modular filter based approach developed by Graizer and Kalkan (2007, 2009) for active tectonic environment in the Western US (WUS). The G15 model is based on the NGA-East database for the horizontal peak ground acceleration and 5%-damped pseudo spectral acceleration RotD50 component (Goulet et al., 2014). In contrast to active tectonic environment the database for the CEUS is not sufficient for creating purely empirical GMPE covering the range of magnitudes and distances required for seismic hazard assessments. Recordings in NGA-East database are sparse and cover mostly range of Mindustry (Vs=2800 m/s). The number of model predictors is limited to a few measurable parameters: moment magnitude M, closest distance to fault rupture plane R, average shear-wave velocity in the upper 30 m of the geological profile VS30, and anelastic attenuation factor Q0. Incorporating anelastic attenuation Q0 as an input parameter allows adjustments based on the regional crustal properties. The model covers the range of magnitudes 4.010 Hz) and is within the range of other models for frequencies lower than 2.5 Hz

  9. IDENTIFYING THE INDUSTRY BUSINESS CYCLE USING THE MARKOV SWITCHING APPROACH IN CENTRAL AND EASTERN EUROPE

    Full Text Available In this article we use a Markov Switching model with two lags to identify and to compare the business cycle in Romania, Czech Republic, Hungary and Poland using data on industrial production for the 1991-2011 period. We use a model with two regimes that reflect the economic expansions and contractions. The Markov Switching models have been widely used in order to detect and to date the business cycle turning points. However, it should be pointed out that the industrial production may have a little bit different dynamics than the quarterly gross domestic product which is the main measure of economic activity. Based on the smoothed regime probabilities the model track three recessionary periods of the Romanian economy in 1991, 1997 and 2009 and two recessionary periods for the other countries in 1991 and 2009. Mean yoy growth of IPI is 5.01% during expansion periods, while it switches to -18.6% during contraction periods for the Romanian economy. In comparison, mean yoy growth of IPI is 7.25% during expansion periods, while it switches to -13.4% during contraction periods for the Poland economy. Furthermore, in Romania, the duration of the three recessions in months was 25, 25 and 9 months. In Poland, the duration of the two recessions was 16 and 10 months. The results of the study may be used in order to compare the business cycle in Central and Eastern European countries with the Euro Area business cycle.

    2015-08-01

    Full Text Available The Central and Eastern European (CEE capital markets (of Poland, Lithuania, Latvia, Estonia, the Czech Republic, Slovakia, Hungary, Ukraine and, to a limited extent, Belarus are gradually evolving towards increased breadth (diversity and depth (liquidity, however, they are still exposed to considerable cross-country volatility and interdependence spill-overs – especially in times of capital flight to more established asset classes (“safe havens”. Sovereign Wealth Funds (SWFs have widely been censured for their undesirable political interference and chronic operational opacity. This paper demonstrates that in CEE, contrary to widespread perceptions attributable to developed markets, SWFs can act as natural and powerful risk mitigators (contributing to a more stable capital base and reduced systemic volatility. Such a proposition is premised on several factors specific to SWFs oriented to CEE. They comprise: strategic long-termism and patience in overcoming interim pricing deficiencies, commitments to elements of a broadly interpreted infrastructure, and absence of overt conflicts of interest with the CEE host economies. The paper, besides reviewing the utilitarianism of SWFs in the CEE’s risk mitigation context, highlights regulatory and technical barriers to more SWF funding for CEE. It also recommends policy measures to the CEE economies aimed at luring more host-friendly SWF investment into the region.

  11. Crustal deformation rates in central and eastern U.S. inferred from GPS

    Science.gov (United States)

    Gan, Weijun; Prescott, William H.

    Analysis of continuous GPS observations between 1996 and 2000 at 62 stations distributed throughout the central and eastern United States suggests that the area is generally stable. Seven of the 62 stations show anomalous velocities, but there is reason to suspect their monument stability. Assuming the remaining 55 stations are stable with respect to interior North America, we have found the North America-ITRF97 Euler vector (-1.88°±1.04°N, 77.67°±0.39°W, 0.201°±0.004° Myr-1) that minimizes the RMS station velocity. Referred to fixed North America, all of these velocities are less than 3.2 mm yr-1. Motion of several stations suggests the Mississippi embayment may be moving southward away from the rest of the continent at a rate of 1.7±0.9 mm yr-1. The motion of the embayment produces a large gradient in velocity which, in turn, implies the highest seismic moment accumulation rate that we found. Although the highest rate is only marginally significant, the fact that it occurs near New Madrid, where earthquake risk is thought to be high, argues that the anomaly may be real. Nevertheless, the identification of the anomaly remains tentative.

    Full Text Available This paper carries out a growth accounting exercise for the 10 Central and Eastern European (CEE countries that are part of the European Union over the period 1993-2008. We estimate the capital share (α from a Cobb-Douglas production function in an intensive form, by employing panel data techniques. The Hausman and Chi-Square tests indicate that a Cross- Section Random Effects with Period Fixed Effects model best suits our data. Based on this model, we find a capital share between 0.45 and 0.83, higher than the usual 0.3-0.4 used in growth accounting literature. When we take into consideration the quality of labour force the estimated capital share slightly decreases, but still remains high, in a range between 0.39 and 0.79. Our growth accounting results reveal that, on average, capital per worker accumulation is the main engine of growth in CEE, followed by the contribution of total factor productivity (TFP. However, when dividing by sub-periods, we found that the contribution of TFP cannot be neglected since during 1997-2004 it proved to be the main engine of growth in some CEE countries (Czech Republic, Slovakia, Hungary, Lithuania and Romania. Some policy implications are offered based on our results.

  13. The lending channel and budget balance: empirical evidences from Central and Eastern European economies

    2013-03-01

    Full Text Available The study aims to deepen the analysis on the indirect dependence of government budget balance on private sector credit flow in the countries of Central and Eastern Europe. The added value of this approach consists of two elements. First, the analysis suggests developing the traditional analytical framework of assessing risks to public finance stability by including second round effects of negative fiscal impulses on credit to private sector during recession periods. Second, the study provides empirical evidence on the importance of economic growth transmission channel for the impact of credit accelerator effects on primary deficit. At the same time, nonperforming loans channel proved to be insignificant, especially in relation to the persistency of last year’s budget deficit and the effects of budget allocations pro-cyclicality. However, loan portfolio quality seems to be more relevant in the case of public debt service, through its influence on the evolution of the yield on long-term government securities that is closely related to sovereign risk premium. Nevertheless, strengthening the financial safety net by the introduction of resolution funds will most probably break the link investors saw between credit portfolio quality and the impending increase in budget spending. This expected development across not only CEE countries, but at the EU level also, will facilitate the isolation of sovereign risk premium from non-performing loans’ dynamics.

    Full Text Available This article evaluates the level of integration of Members of the European Parliament from Central and Eastern Europe in the European Parliament after the EU enlargements of 2004 and 2007. The main objective is to address the puzzle of how the European Parliament’s political groups could maintain or even increase their voting cohesion after the influx of a significantly large number of new MEPs coming from countries with different historical experience, socio-economic characteristics, and political and party systems. Three indicators of MEP integration are defined: integration into parliamentary leadership, integration into parliamentary work, and integration into voting patterns. The article uses data from the VoteWatch.eu website on MEPs’ activities and voting between the years 2004-2011, as well as data from official documents of the European Parliament and its political groups. Analysis of the data reveals that the new member states’ MEPs were significantly under-represented in parliamentary leadership and key legislative activities, despite the fact that their voting loyalty to their political groups was greater than that of their colleagues from older member states.

    2013-02-01

    Full Text Available This article analyses the transition from the traditional hierarchical governance of natural resources in Central and Eastern Europe towards the new forms of market governance of protected areas, including the introduction of fees and compensation. Our conceptual framework suggests that markets can be effective in governing transactions that involve low asset specificity and low frequency of disturbances. However, the introduction of markets should be accompanied by appropriate rules of market organization that particularly regulate their monitoring and impose sanctions in cases of mismanagement. The analysis of market governance in Poland, the Czech Republic and Slovakia reveals that in the face of decreasing funding for biodiversity protection and state budgetary problems, markets are more a necessity than a means to improve resource management. Although markets should complement rather than substitute traditional forms of governance, for certain types of transactions, markets are useful. They can be effectively implemented, provided that property rights are recognized and legal settings that regulate the monitoring and enforcement of market rules are set up.

    Interpretations of the aeromagnetic maps delineated four regional structural trends oriented due NNW, NW, ENE and E–W directions. They are identified as strike-slip faults, which coincide well with field observations, where NW-trending faults cut and displace right laterally ENE-trending older ones. The interaction between these two strike-slip fault systems confining the albite granite is easily identified on the regional data presenting longer wavelength anomalies, implying deep-seated structures. They could represent potential pathways for migration of enriched mineralized fluids. Geochemically, albite granites of peraluminous characteristics that had suffered extensive post-magmatic metasomatic reworking, resulted into development of (Zr, Hf, Nb, Ta, U, Th, Sn and albite-enriched and greisenized granite body of about 600 m thick, and more than 3 km in strike length. The albite granite is characterized by sharp increase in average rare metal content: Zr (830 ppm, Hf (51 ppm, Nb (340 ppm, Ta (44 ppm, and U (90 ppm. Thorite, uranothorite, uraninite and zircon are the main uranium-bearing minerals of magmatic origin within the enclosing granite. However, with respect to Zr, Nb, and Ta, the albitized granite can be categorized as rare metal granite. The integration of airborne geophysical (magnetic and γ-ray spectrometric, geological, geochemical and mineralogical data succeeded in assigning the albite granite of Um Naggat pluton as a mineralized zone. This zone is characterized by its high thorium and uranium of hydrothermal origin as indicated by its low Th/U ratio, with rare metals mineralization controlled by two main structural trends in the NW- and ENE-directions.

In this occurrence, the uranium assumes different forms, including its presence as discrete, visible, secondary minerals, rare uraninite and its association with the jasperoid and silica veinlets. However,in some other parts of the sheared zone, the uranium was found to be solely incorporated with fluorite crystals,filling veinlet sand fractures with out any other manife station.This paper focuses ont her elevant mineralogical and geochemical characteristics of this unique fluorite variety.In addition to an investigation with binocular and polarizing microscopes, the separated fluorite grains were analyzed usingan environmental scanning electronmicroscope(ESEM and a field-emission scanning electron microscope.In addition to this,some fluorite crystals were subjected to electron microprobe analyses. While the fluorite accounted for as much as 20% of the sheared granite samples studied, it was found to range from 82 to 96 % in the different size fractions of the separated heavy mineral content. In some parts of the separated fluorite crystals,uranium inquantities of up to 2200 ppm was found to be heterogeneously distributed in the fluoritelattice,regardless of its coloration.

The method of cataclastic analysis in its earliest version was applied in 1996 and 1997 when seismic data from the first catalog were analyzed, and it yielded only parameters of stress ellipsoids; the reconstructions were published in a Russian-Chinese journal (it does not exist now. In this paper, these reconstructions are presented in new graphical formats of GIS. Data from the Global CMT Database were analyzed by the method of cataclastic analysis in the new revision with application of its stages 1 and 2. Based on the calculations, orientations of axes of principal stresses, types of ellipsoids, correlations between spherical and deviatoric components of stress tensors, and reduced stresses were determined. The two sets of reconstructions are compared in this paper. The catalog of earthquake focal mechanisms for the period from 1904 to 1992 consolidated information provided by different authors, and thus focal data for many seismic events were highly inconsistent; therefore, the reliability of reconstructions based on such data seems to be lower than that on the basis the Global CMT Database for the period from 1978 to 2010. Some of the reconstructed stress tensor parameters are mapped. For the areas which data are given in the Global CMT Database and considered as more reliable, mapping is based on stress parameters calculated from such data. For the areas that are not covered by the

    The wild boar (Sus scrofa) is one of the most widely distributed mammals in Europe. Its demography was affected by various events in the past and today populations are increasing throughout Europe. We examined genetic diversity, structure and population dynamics of wild boar in Central and Eastern Europe. MtDNA control region (664 bp) was sequenced in 254 wild boar from six countries (Poland, Hungary, Belarus, Ukraine, Moldova and the European part of Russia). We detected 16 haplotypes, all known from previous studies in Europe; 14 of them belonged to European 1 (E1) clade, including 13 haplotypes from E1-C and one from E1-A lineages. Two haplotypes belonged respectively to the East Asian and the Near Eastern clade. Both haplotypes were found in Russia and most probably originated from the documented translocations of wild boar. The studied populations showed moderate haplotype (0.714±0.023) and low nucleotide diversity (0.003±0.002). SAMOVA grouped the genetic structuring of Central and Eastern European wild boar into three subpopulations, comprising of: (1) north-eastern Belarus and the European part of Russia, (2) Poland, Ukraine, Moldova and most of Belarus, and (3) Hungary. The multimodal mismatch distribution, Fu's Fs index, Bayesian skyline plot and the high occurrence of shared haplotypes among populations did not suggest strong demographic fluctuations in wild boar numbers in the Holocene and pre-Holocene times. This study showed relatively weak genetic diversity and structure in Central and Eastern European wild boar populations and underlined gaps in our knowledge on the role of southern refugia and demographic processes shaping genetic diversity of wild boar in this part of Europe.

    To characterize Late Pleniglacial (LPG: 26.5-15 ka cal BP) and particularly Last Glacial Maximum (LGM: 21 ± 2 ka cal BP) vegetation and climate, fossil pollen assemblages are often compared with modern pollen assemblages. Given the non-analogue climate of the LPG, a key question is how glacial pollen assemblages and thereby vegetation compare with modern vegetation. In this paper we present three LPG pollen records from the Carpathian Basin and the adjoining Carpathian Mountains to address this question and provide a concise compositional characterization of the LPG vegetation. Fossil pollen assemblages were compared with surface pollen spectra from the Altai-Sayan Mountains in southern Siberia. This area shows many similarities with the LPG vegetation of eastern-central Europe, and has long been considered as its best modern analogue. Ordination and analogue matching were used to characterize vegetation composition and find the best analogues. Our results show that few LPG pollen assemblages have statistically significant analogues in southern Siberia. When analogue pairings occur they suggest the predominance of wet and mesic grasslands and dry steppe in the studied region. Wooded vegetation types (continental and suboceanic hemiboreal forest, continental taiga) appear as significant analogues only in a few cases during the LGM and more frequently after 16 ka cal BP. These results suggest that the LPG landscape of the Carpathian Basin was dominated by dry steppe that occurred outside the river floodplains, while wet and mesic grasslands occurred in the floodplains and on other sites influenced by ground water. Woody vegetation mainly occurred in river valleys, on wet north-facing hillsides, and scattered trees were likely also present on the loess plateaus. The dominant woody species were Larix, Pinus sylvestris, Pinus mugo, Pinus cembra, Picea abies, Betula pendula/pubescens, Betula nana, Juniperus, Hippophaë rhamnoides, Populus, Salix and Alnus.

    Aided by its consultant, the US Geologic Survey (USGS), the Nuclear Regulatory Commission (NRC) reviewed ''Seismic Hazard Methodology for the Central and Eastern United States.'' This topical report was submitted jointly by the Seismicity Owners Group (SOG) and the Electric Power Research Institute (EPRI) in July 1986 and was revised in February 1987. The NRC staff concludes that SOG/EPRI Seismic Hazard Methodology as documented in the topical report and associated submittals, is an acceptable methodology for use in calculating seismic hazard in the Central and Eastern United States (CEUS). These calculations will be based upon the data and information documented in the material that was submitted as the SOG/EPRI topical report and ancillary submittals. However, as part of the review process the staff conditions its approval by noting areas in which problems may arise unless precautions detailed in the report are observed. 23 refs.

    Full Text Available Understanding the spectral properties of the carbonatized ultramafic mantle xenoliths and their host olivine basalts exposed at Jabal Al Maqtal strike-slip basin, south Eastern Desert, Egypt using portable ASD FieldSpec is the main task of this article. Field data revealed the presence of ultramafic mantle xenoliths at different stratigraphic levels within Jurassic olivine basalts. Ultramafic mantle xenoliths are recorded within highly altered olivine basalt topped by hard, compact brown conglomerate (erosional surface of 1.5 m thick. They have different sizes (5–25 cm and shapes (rounded, sub-rounded and elliptical. The spectral data are collected using ASD FieldSpec in sunny, free-cloud day. Data measurements were resampled as reference-target scan. Nearly all the mineralogical constituents of the studied ultramafic mantle xenoliths were replaced by Mg-Free (<0.5 wt% calcium carbonate (calcite. Spectrally the ultramafic mantle xenoliths can be categorized into two main groups based on their Fe and Mn content which produce absorption features at shorter wavelength regions. The spectral profile of the first group shows a pronounced absorption features around 0.50 μm, 0.65 μm and 0.90 μm wavelength regions. These features are attributed to the electronic processes within the unfilled d-shells of transition Mn2+ and Fe2+ metal cations (MnO and Fe2O3 content are 2.11 wt% and 12.6 wt% respectively as indicated by XRF analyses. The spectral profile of the second group shows a very week absorption features in shorter wavelength regions which is attributed to the low MnO (0.7 wt% and Fe2O3 (2.17 wt% content. Both ultramafic mantle xenoliths groups show pronounced absorption features in longer wavelength regions (1.8–2.55 μm. Inspection of the spectral profiles of the mantle xenoliths revealed the presence of six absorption features around 1.80 μm, 1.95 μm, 2.00 μm, 2.35 μm, 2.4 μm. and 2.5 μm wavelength regions which are

    Mantle spinel peridotites beneath the Arabian Nubian Shield (ANS) in the Eastern Desert (ED) of Egypt were formed in arc stage in different tectonic setting. Thus they might subject to exchange with the crustal material derived from recycling subducting oceanic lithosphere. This caused metasomatism enriching the rocks in incompatible elements and forming non-residual minerals. Herein, we present mineral chemical and geochemical data of four ophiolitic mantle slice serpentinized peridotites (W. Mubarak, G. El-Maiyit, W. Um El Saneyat and W. Atalla) widely distributed in the ED. These rocks are highly serpentinized, except some samples from W. Mubarak and Um El-Saneyat, which contain primary olivine (Fo# = 90-92 mol %) and orthopyroxene (En# = 86-92 mol %) relics. They have harzburgite composition. Based on the Cr# and Mg# of the unaltered spinel cores, all rocks formed in oceanic mantle wedge in the fore-arc setting, except those from W. Atalla formed in nascent fore-arc. This implies that the polarity of the subduction during the arc stage was from the west to the east. These rocks are restites formed after partial melting between 16.58 in W. Atalla to 24 % in G-El Maiyit. Melt extraction occurred under oxidizing conditions in peridotites from W. Mubarak and W. Atalla and under reducing conditions in peridotites from G. El-Maiyit and Um El-Saneyat. Cryptic metasomatism in the studied mantle slice peridotites is evident. This includes enrichment in incompatible elements in minerals and whole rocks if compared with the primitive mantle (PM) composition and the trend of the depletion in melt. In opx the Mg# doesn't correlate with TiO2, CaO, MnO, NiO and Cr2O3concentrations. In addition, in serpentinites from W. Mubarak and W. Atalla, the TiO2spinel is positively correlated with the TiO2 whole-rock, proposing enrichment by the infiltration of Ti-rich melts, while in G. El- Maiyit and Um El-Saneyat serpentinites they are negatively correlated pointing to the reaction

    The Mesozoic (Upper Jurassic-Lower Cretaceous) deeply buried gas reservoir play in the central and eastern Gulf coastal plain of the United States has high potential for significant gas resources. Sequence-stratigraphic study, petroleum system analysis, and resource assessment were used to characterize this developing play and to identify areas in the North Louisiana and Mississippi Interior salt basins with potential for deeply buried gas reservoirs. These reservoir facies accumulated in Upper Jurassic to Lower Cretaceous Norphlet, Haynesville, Cotton Valley, and Hosston continental, coastal, and marine siliciclastic environments and Smackover and Sligo nearshore marine shelf, ramp, and reef carbonate environments. These Mesozoic strata are associated with transgressive and regressive systems tracts. In the North Louisiana salt basin, the estimate of secondary, nonassociated thermogenic gas generated from thermal cracking of oil to gas in the Upper Jurassic Smackover source rocks from depths below 3658 m (12,000 ft) is 4800 tcf of gas as determined using software applications. Assuming a gas expulsion, migration, and trapping efficiency of 2-3%, 96-144 tcf of gas is potentially available in this basin. With some 29 tcf of gas being produced from the North Louisiana salt basin, 67-115 tcf of in-place gas remains. Assuming a gas recovery factor of 65%, 44-75 tcf of gas is potentially recoverable. The expelled thermogenic gas migrated laterally and vertically from the southern part of this basin to the updip northern part into shallower reservoirs to depths of up to 610 m (2000 ft).

    Summary Background The aim of this study was to assess and compare patients’ access to biologic anti-RA drugs in selected Central and Eastern European (CEE) countries and to analyze the determinants of differences between countries. Material/Methods This is a multi-country survey study, based on a combination of desk research and direct contact with national RA stakeholders. Data was collected using a pre-defined questionnaire. Affordability was measured using an affordability index, calculated comparing the index of health care expenditures to the price index, using Poland as an index of 1. Results The percentage of patients on biologic treatment in 2009 was highest in Hungary (5% RA patients on biologic treatment), followed by Slovenia (4.5%), Slovakia (3.5%), Czech Republic (2.92%), Romania (2.2%), Estonia (1.8%), and Croatia, Serbia, Poland (below 1.5%). Infliximab, etanercept, adalimumab and rituximab were included in the reimbursement system in all countries, but abatacept and tocilizumab were included only in Slovakia. In Slovenia, public payer covered 75% of the price, and 25% is covered by supplementary health insurance; in Bulgaria public payer covered 50% of etanercept and adalimumab costs, and 75% of rituximab cost. In other countries, biologic drugs are reimbursed at 100%. Affordability index for biologic drugs was the lowest in Slovenia (0.4). In each country national guidelines define which patients are eligible for biologic treatment. Disease Activity Score (DAS28) of over 5.1 and failure of 2 or more disease-modifying anti-RA drugs, including methotrexate, are commonly used criteria. Conclusions The most important factors limiting access to biologic anti-RA treatment in the CEE region are macroeconomic conditions and restrictive treatment guidelines. PMID:21455121

    Full Text Available One of the positive effects of the financial crises is the increasing concern of the supervisors regarding the financial system’s stability. There is a need to strengthen the links between different financial components of the financial system and the macroeconomic environment. Banking systems that have an adequate capitalization and liquidity level may face easier economic and financial shocks. The purpose of this empirical study is to identify the main determinants of the banking system’s stability and soundness in the Central and Eastern Europe countries. We asses the impact of different macroeconomic variables on the quality of capital and liquidity conditions and examine the behaviour of these financial stability indicators, by analyzing a sample of 10 banking systems during 2000-2011. The availability of banking capital signals the banking system’s resiliency to shocks. Capital adequacy ratio is the main indicator used to assess the banking fragility. One of the causes of the 2008-2009 financial crisis was the lack of liquidity in the banking system which led to the collapse of several banking institutions and macroeconomic imbalances. Given the importance of liquidity for the banking system, we propose several models in order to determine the macroeconomic variables that have a significant influence on the liquid reserves to total assets ratio. We found evidence that GDP growth, inflation, domestic credit to private sector, as well as the money and quasi money aggregate indicator have significant impact on the banking stability. The empirical regression confirms the high level of interdependence of the real sector with the financial-banking sector. Also, they prove the necessity for an effective macro prudential supervision at country level which enables the supervisory authorities to have an adequate control over the macro prudential indicators and to take appropriate decisions at the right time.

    Marginalised Roma communities in European countries live in substandard housing conditions the improvement of which has been one of the major issues of the Decade of Roma Inclusion, the ongoing intergovernmental European Roma programme. The paper presents EU-funded health impact assessments of national Roma housing policies and programmes in 3 Central and Eastern European countries in light of the evaluation of a completed local project in a fourth CEE country so as to compare predicted effects to observed ones. Housing was predicted to have beneficial health effects by improving indoor and outdoor conditions, access to services, and socioeconomic conditions. Negative impacts were predicted only in terms of maintenance expenses and housing tenure. However, observed impacts of the completed local project did not fully support predictions especially in terms of social networks, satisfaction with housing and neighbourhood, and inhabitant safety. In order to improve the predictive value of HIA, more evidence should be produced by the careful evaluation of locally implemented housing projects. In addition, current evidence is in favour of planning Roma housing projects at the local rather than at the national level in alignment with the principle of subsidiarity. - Highlights: Black-Right-Pointing-Pointer Predictive validity of HIA of national Roma housing policies - in light of current evidence - is low. Black-Right-Pointing-Pointer Implemented housing projects should be comprehensively evaluated to improve reliability of HIA. Black-Right-Pointing-Pointer Roma housing projects should be planned at the local rather than at the national level. Black-Right-Pointing-Pointer HIA should be used to plan Roma housing projects at the local level.

    We present a receiver function (RF) study of the mantle transition zone (MTZ) and upper mantle in central-eastern Greenland. Our results are based on data from 18 temporary broad-band seismometers and 5 additional stations from the GLISN and GLATIS networks. The stations were operating in the region between Scoresby Sund and Summit (~ 70 ° N) with half of them installed on ice, the other half on bedrock. For our analysis we calculated low frequency PRF and SRF, which use the difference in travel times between converted and not converted phases at discontinuities. We see clear signals from P410s and P660s in most of our PRF and from S410p in the SRF. Their delay times suggest a surprisingly thin MTZ for most parts of the study area with up to 25 km of thinning compared to standard Earth models. The only exception is a small region in the centre of the study area, which shows times close to standard. It is mainly the delay time for P410s, that varies, while P660s is stable throughout our study area. This indicates, that the thinning of the MTZ is mainly due to topography on the 410-discontinuity. We furthermore observe an M-shaped signal for P410s at stations in the western part around Summit. A similar, complicated signal has been observed previously in different settings and is interpreted as a thin low velocity layer between 410 km and 520 km. In addition we jointly inverted the PRF and SRF for upper mantle velocities. These results show velocities slower than IASP91 for the entire study area. Both the low velocities in the upper mantle and the thinning of the MTZ are in contrary to simple models of old continental shields and might indicate a fairly recent heating event.

  13. New Bangalores? The role of Central and Eastern Europe in business and IT services offshoring

    Directory of Open Access Journals (Sweden)

    Zoltan Gal

    2013-09-01

    Full Text Available The paper discusses how the second global shift in business services provision and corporate restructuring open up new offshoring opportunities into Central and Eastern Europe (CEE. It explores three issues: First, it builds upon the theoretical framework of the ‘new paradigm of globalization, which considers offshoring as one of the most important globalizing forces of recent time. This results in a shift in global trade, namely from ‘trade in goods’ to ‘trade in tasks’ determined by the changing trends in the division of labour. Second, the paper gives an overview of services relocation into CEE in comparison with its Asian counterparts. As the EU expanded eastwards, the opportunities for European corporations to offshore their business services to these ‘nearshore’ locations increased. Building on the region’s nearshoring advantages such as geographical-cultural proximity and on their multilingual graduate sup ply, CEE is likely to utilise more value added quality-driven BPO and KPO services. Third, the paper examines the implications of offshoring for the home markets in CEE assessing its impact on their locations. It reveals the role of offshoring activities in the metropolitan transformation and discusses the factors that make the capital cities an increasingly attractive option for companies to relocate their services. Despite CEE has taken advantage on the trend supported by the global service delivery models reducing dependency on any single location, its further growth may be influenced by the worsening macro-conditions, and future prospect of the region depends largely on government incentives and on the success of exploiting talent pools offered by its provincial cities.

  14. Contribution of oceanic and vegetation feedbacks to Holocene climate change in Central and Eastern Asia

    Full Text Available The impact of vegetation-atmosphere and ocean-atmosphere interactions on the mid- to late Holocene climate change as well as their synergy is studied for different regions in Central and Eastern Asia (60–140° E, 0–55° N, giving consideration to the large climatic and topographical heterogeneity in that area. With main focus on the Asian monsoon, we concentrate on both, temperature and precipitation changes. For our purpose, we analyze a set of coupled numerical experiments, performed with the Earth system model ECHAM5/JSBACH-MPIOM under present-day and mid-Holocene (6 k orbital configurations (Otto et al., 2009. Like expected, the temperature change caused by the insolation forcing reveals an enhanced seasonal cycle, with a pronounced warming in summer (0.7 K and autumn (1 K and a cooling in the other seasons (spring: −0.8 K; winter −0.5 K. Most of this change can be attributed to the direct response of the atmosphere, but the ocean, whose reaction has a lagged seasonal cycle (warming in autumn and winter, cooling in the other seasons, strongly modifies the signal. The simulated contribution of dynamic vegetation is small and most effective in winter, where it slightly warms the near-surface atmosphere (≈0.05 K. Concerning the precipitation, the most remarkable change is the postponement and enhancement of the Asian monsoon (0.27 mm/d in summer, 0.23 mm/d in autumn, mainly related to the direct atmospheric response. On regional average, the ocean (ca. 0.05 mm/d amplifies the direct effect, but tends to weaken the East Asian summer monsoon and strongly increases the Indian summer monsoon rainfall rate (0.68 mm/d. The influence of dynamic vegetation and synergy effects on precipitation is comparatively small.

  15. Earthquake Rate Models for Evolving Induced Seismicity Hazard in the Central and Eastern US

    2015-12-01

    Injection-induced earthquake rates can vary rapidly in space and time, which presents significant challenges to traditional probabilistic seismic hazard assessment methodologies that are based on a time-independent model of mainshock occurrence. To help society cope with rapidly evolving seismicity, the USGS is developing one-year hazard models for areas of induced seismicity in the central and eastern US to forecast the shaking due to all earthquakes, including aftershocks which are generally omitted from hazards assessments (Petersen et al., 2015). However, the spatial and temporal variability of the earthquake rates make them difficult to forecast even on time-scales as short as one year. An initial approach is to use the previous year's seismicity rate to forecast the next year's seismicity rate. However, in places such as northern Oklahoma the rates vary so rapidly over time that a simple linear extrapolation does not accurately forecast the future, even when the variability in the rates is modeled with simulations based on an Epidemic-Type Aftershock Sequence (ETAS) model (Ogata, JASA, 1988) to account for earthquake clustering. Instead of relying on a fixed time period for rate estimation, we explore another way to determine when the earthquake rate should be updated. This approach could also objectively identify new areas where the induced seismicity hazard model should be applied. We will estimate the background seismicity rate by optimizing a single set of ETAS aftershock triggering parameters across the most active induced seismicity zones -- Oklahoma, Guy-Greenbrier, the Raton Basin, and the Azle-Dallas-Fort Worth area -- with individual background rate parameters in each zone. The full seismicity rate, with uncertainties, can then be estimated using ETAS simulations and changes in rate can be detected by applying change point analysis in ETAS transformed time with methods already developed for Poisson processes.

    Stand growth and developmental processes were investigated in Pinus densiflora Siebold et Zucc. stands of different ages in the central eastern region of Korea. Stands were inventoried and five trees per stand were sampled for stem analysis, age estimation, and growth analysis. More than 80% of sampled trees in a stand were established within 3-5 years, and most stands had a single cohort structure. The initial growth of pine seedlings was slow, but the height growth accelerated beyond 2-3 m height, 5-10 years after establishment. Linear growth was maintained until 10-12 m height, at which suppressed trees fell behind and might die out. The young stand was composed of pure pines, while few pine seedlings and saplings were found in the understory of older stands. The peak of diameter growth rate occurred around 5-15 years after tree establishment, implying that competition begins during that period. The pine stand development follows four stages: (1) the young stage when the growth rate increases and peaks; (2) the height competition stage when trees focus on height growth for light while maintaining a narrow DBH and height distribution; (3) the differentiation stage when suppressed trees die out, and the DBH distribution becomes wider; and (4) the mature stage when stands have a multi-canopy structure with a wide DBH and height distribution, while the understory is dominated by other tree species. The changes in growth rates and stand structure through forest development would be implemented to predict alterations of above-ground carbon sequestration rates.

    Biological drugs opened up new horizons in the management of inflammatory bowel diseases (IBD). This study focuses on access to biological therapy in IBD patients across 9 selected Central and Eastern European (CEE) countries, namely Bulgaria, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania and Slovakia. Literature data on the epidemiology and disease burden of IBD in CEE countries was systematically reviewed. Moreover, we provide an estimation on prevalence of IBD as well as biological treatment rates. In all countries with the exception of Romania, lower biological treatment rates were observed in ulcerative colitis (UC) compared to Crohn's disease despite the higher prevalence of UC. Great heterogeneity (up to 96-fold) was found in access to biologicals across the CEE countries. Poland, Bulgaria, Romania and the Baltic States are lagging behind Hungary, Slovakia and the Czech Republic in their access to biologicals. Variations of reimbursement policy may be one of the factors explaining the differences to a certain extent in Bulgaria, Latvia, Lithuania, and Poland, but association with other possible determinants (differences in prevalence and incidence, price of biologicals, total expenditure on health, geographical access, and cost-effectiveness results) was not proven. We assume, nevertheless, that health deterioration linked to IBD might be valued differently against other systemic inflammatory conditions in distinct countries and which may contribute to the immense diversity in the utilization of biological drugs for IBD. In conclusion, access to biologicals varies widely among CEE countries and this difference cannot be explained by epidemiological factors, drug prices or total health expenditure. Changes in reimbursement policy could contribute to better access to biologicals in some countries.

    The increased deployment of renewable energy and energy efficiency technologies (RE&EET) in the South Eastern Mediterranean (SEMED) region and in the Early Transition Countries (ETC) could bring a host of benefits, including enhanced energy security, increased national revenues and environmental gains. A new IEA Insights paper considers policy options for supporting the deployment of RE&EET, as well as the surrounding factors that can enable – or indeed impede – the successful implementation of such support policies in both regions. Drawing on a wealth of IEA analyses and policy experiences globally, the paper: provides a summary of the energy profiles of the ETC and SEMED regions; highlights overarching, ''enabling'' factors that can help to set the necessary foundations for the successful implementation of policy to support RE&EET deployment; analyses policy options for both RE and EE, drawing on practical examples and highlighting indicative policies that correspond with varying levels of market maturity; and provides a checklist for assessing the level of supportiveness of national policy frameworks for RE&EET. The paper concludes by pointing to the significant potential for energy efficiency and renewable energy gains in both regions.

    Today, HF radar is recognized as internationally cost-effective and efficient solution to provide near-real time measurements that cover a large area continuously over time for ocean hazards warning and long term ocean monitoring studies such as, seasonal forecasts of climate, hurricanes, s torm surges and large-scale ocean circulation changes. These radar systems recently became an operational tool in coastal monitoring worldwide. They are used for many operational applications that include ship detection, tracking, guidance, distribution of pollutants, fishery and oceanography. HF radar data used for the tsunami warnings, can also be used for the other purposes and be of potential interest to wide application area users and stakeholders. Moreover multi user applications will ensure the system is maintained operationally over the long term. Hence the system is cost effective also with regards to maintenance. New algorithms allow useful detection and verification for tsunami detection. While technical monitoring capacity and the algorithms for tsunami detection is improved significantly, further studies are required to obtain complete wave height determination. We analysed the available technology and algorithms for the purpose of tsunami detection in the central-eastern Mediterranean and its connected Seas (Aegean and Black Sea). Since the study area is characterized by narrow continental shelf area, the HF radar observation for the purpose of tsunami detection is possible in restricted areas. While extensive continental shelves in the northeastern Black Sea and along the coast of Tunisia in the central Mediterranean let tsunami detection 2.5 hours before tsunami waves hit the coast, the detection is possible around 1 hr or less in advance for the remaining basins with wide continental shelf areas. The bathymetric structure is important for deciding the applicability of HF radar systems for the tsunami detection in continental shelf areas, which can be covered by

    Agritourism provides ecological tourist services for urban dwellers in rural areas. Agritourism farms offer space and attractive scenery for people seeking to rest in quiet place and wanting healthy, outdoor recreational activities. The high epidemiological standard of agritourism farms is beneficial for the health of the farm owners and the guests. Upgraded level of the farm sanitation, also from parasitological point of view is of great importance, especially that among agritourism farms guests predominate families with small children. A field survey was carried out in 57 farms in central-eastern Poland to evaluate the environmental risk factors for geohelminth infections on agritourism farms offering tourist services for urban dwellers. Samples of soil were collected from 76 sites, i.e. yards surrounding houses, vegetable, fruit and flower gardens, playgrounds and sandpits. In addition, samples were taken from 27 public places of recreation (playgrounds at forest clearing) visited by agritourism farm guests. During visits the farms were inspected and the owners were questioned about their awareness of the threat of parasitic infections. Soil contamination with geohelminth eggs was found in 4 examined farms (7.0%), in one locality on each farm. The eggs of Toxocara spp. and Ascaris spp. were detected in single samples from 3 backyards (6.4%) and one sandpit (10.0%). In the soil samples from places of recreation outside the farms eggs of human or animal helminths were not identified. The results of this study showed that the risk of helminth infections on agritourism farms is low, since geohelminth eggs (1-3 per sample) were detected only in four samples (0.5%) among 760 collected from farms households. The farm owners must be aware of the importance of preventive measures to eliminate the environmental contamination with eggs of zoonotic soiltransmitted helminths. Special attention should be paid to the risk of intestinal parasites of cats of semi domestic

    Full Text Available The main objective of the project “Mechanization and Energy use in selected arable farms in Central and South Eastern Europe (CASEE” was to analyse energy characteristics of arable farming in Slovak Republic, Romania, Serbia and Austria, to compare results and identify possibilities of its improvements. The large scale farms are: the university farm of the Slovak University of Agriculture (SK with 1.112 ha arable land, a cooperative farm in Risnovice (SK with an arable land of 1.266 ha, a family farm in Apahida-Transylvania (RO with 400 ha, a farm in Viisoara-Transylvania (RO with 600 ha, a family farm in Sremska Mitrovica (SRB with an arable land of 115 ha, a family farm near Novi Sad (SRB with an arable land of 450 ha and a family farm in Ansfelden/Linz (A with 368 ha. The farms were visited by the interviewer once or more times and the relevant data, used machinery, quantity of inputs, e.g. fuel, pesticides, fertilizer, seed and yields of harvested crops, were recorded, for the production season 2012. After collection of the basic data all energy inputs and outputs, energy content of crops, were calculated in accordance with data and procedure defined by CIGR (International Commission of Agricultural and Biosystems Engineering, Handbook Volume V – Energy and Biomass Engineering (1999. Energy input and net energy gain, expressed in MJ/ha, were used to calculate energy characteristics of crops’ production: energy productivity - kg/MJ, energy efficiency index, energy ratio, energy intensity - MJ/kg, fuel intensity - L/kg. The intensity of all used farm inputs (fuel, seeds, fertilizer and pesticide in crop production systems influences the energy efficiency. The fuel consumption for winter wheat production of the analysed farms ranges between 54 and 91 l/ha. The mean energy ratio (energy-output/energy-input for winter wheat is 5.6 with ranges between 4.8 and 7.1. Besides the fuel consumption the energy-input via the nitrogen-fertilizer is

    Stable isotopic ratios of carbon and oxygen (??13C and ??18O) from mollusk shells reflect the water quality characteristics of Florida Bay and can be used to characterize the great temporal variability of the bay. Values of ?? 18O are directly influenced by temperature and evaporation and may be related to salinity. ??13C values of ??13C are sensitive to organic and inorganic sources of carbon and are influenced by productivity. Analyses of eight mollusk species from five short-core localities across Florida Bay show large ranges in the values of ??13C and ??18O, and reflect the variation of the bay over decades. Samples from southwestern Florida Bay have distinct ??13C values relative to samples collected in northeastern Florida Bay, and intermediate localities have intermediate values. 13C values of ??13C grade from marine in the southwest bay to more estuarine in the northeast. Long cores (> 1 m) with excellent chronologies were analyzed from central and eastern Florida Bay. Preliminary analyses of Brachiodontes exustus and Transenella spp. from the cores showed that both ??13C and ??18O changed during the first part of the twentieth century. After a century of relative stability during the 1800s, ??13C decreased between about 1910 and 1940, then stabilized at these new values for the next five decades. The magnitude of the reduction in ??13C values increased toward the northeast. Using a carbon budget model, reduced ??13C values are interpreted as resulting from decreased circulation in the bay, probably associated with decreased freshwater flow into the Bay. Mollusk shell ??18O values display several negative excursions during the 1800s, suggesting that the bay was less evaporitic than during the twentieth century. The isotope records indicate a fundamental change took place in Florida Bay circulation early in the twentieth century. The timing of the change links it to railroad building and early drainage efforts in South Florida rather than to flood control

    The recent roducts of the Ozone Monitoring Instrument (OMI) retrieved by Liu et al. (2010) revealed spatial and temporal variations in ozone distributions in multiple tropospheric layers. We compared the OMI-derived ozone over Beijing with the airborne measurements conducted by the Measurement of Ozone and Water Vapor by Airbus In-Service Aircraft (MOZAIC) program. The reliability of the OMI ozone retrievals was verified at the lower troposphere under enhanced ozone conditions (Hayashida et al. 2015). Ozone enhancement was clearly observed over Central and Eastern China (CEC), with Shandong Province as its center and most notably in June in any given year. The seasonality of the ozone enhancement was similar throughout the nine-year OMI measurement period of 2005 to 2013. As introduced by Hayashida et al. (2015), we have defined ΔO3 as the difference between the retrieved ozone and a priori value. To identify the area of significant ozone enhancement in further detail, the areas whose ΔO3 show similar seasonal variation were grouped into a cluster using the statistical tool R. As a result, the area covering the provinces of Shandong, Hebei, and Shanxi presents a clear seasonal variation, with the maximum in June. The time series of ΔO3 at around 115-125°E along 36°N indicate clear seasonal variation with significant enhancement in June or July every year. At the western locations (<110°E), there is only a slight ozone enhancement in summer. In the east of the CEC, the amplitude of ozone enhancement in summer diminishes toward the east, as observed at 130°E, suggesting an outflow of ozone plumes from China. The lower tropospheric ozone distribution maps retrieved using OMI products are generally consistent with the results from the model simulations by MRI-CCM2 of the Meteorological Research Institute Japan as far as emissions due to industrial activities and automobile exhaust are concerned, although there are still a few differences in the ozone mixing

    The sandy land in the southern region of the Tengger Desert is adjacent to cities and towns, and land desertification poses a threat to the livelihood and production of local residents. To determine dynamic changes in local desertification, five periods (1973, 1987, 1992, 2001, and 2009) of remote sensing data are studied by remote sensing (RS) and geographic information system (GIS). The desert contraction area is primarily centered around three units (Wuwei, Gulang, and Jingtai) and nearby regions of Zhongwei City. The primary desert expansion areas include the west side of Helan Mountain (WSHM), the Central Mountainous Area (CMA), and the eastern and western Zhongwei units far from towns. From 1973 to 2009, the degree of change in the contracting part of the primary desert expansion unit showed an increasing trend; in brief, most of the desert (especially after 2001) has been developing in a direction in which desertification has been gradually controlled. The primary desert expansion areas are less affected by human activity, but they are primarily controlled by natural factors (especially wind and terrain). The desert contraction areas occur around the towns and nearby regions with frequent human activity; desertification is primarily controlled by human factors. With rapid economic development (especially after 2000), the scale of the cultivated area, town, and ecological protection engineering has gradually expanded, and the latter two are primarily built on a previous desert, which is the root cause of the reduction in the desert areas around the towns and the shrinkage toward north of border. Therefore, reasonable and effective human activity in the southern region of the Tengger Desert is playing a crucial role in preventing desertification.

    Computation of probabilistic earthquake hazard requires an estimate of Mmax, the maximum earthquake magnitude thought to be possible within a specified geographic region. This report is Part A of an Open-File Report that describes the construction of a global catalog of moderate to large earthquakes, from which one can estimate Mmax for most of the Central and Eastern United States and adjacent Canada. The catalog and Mmax estimates derived from it were used in the 2014 edition of the U.S. Geological Survey national seismic-hazard maps. This Part A discusses prehistoric earthquakes that occurred in eastern North America, northwestern Europe, and Australia, whereas a separate Part B deals with historical events.

    Full Text Available The pronghorn spiny lobster Panulirus penicillatus is a highly valuable species which is widely distributed in Indo-West Pacific and Eastern Pacific regions. Mitochondrial DNA control region sequences (566–571 bp were determined to investigate the population genetic structure of this species in the Indian Ocean. In total, 236 adult individuals of Panulirus penicillatus were collected from five locations in the Indian Ocean region. Almost all individuals had a unique haplotype. Intrapopulation haplotype (h and nucleotide (π diversities were high for each locality, ranging from h = 0.9986–1.0000 and π = 0.031593–0.043441. We observed distinct genetic isolation of population located at the northwestern and southwestern edge of the species range. Gene flow was found within localities in the central and eastern region of the Indian Ocean, probably resulting from an extended planktonic larval stage and prevailing ocean currents.

    This report describes a new seismic source characterization (SSC) model for the Central and Eastern United States (CEUS). It will replace the Seismic Hazard Methodology for the Central and Eastern United States, EPRI Report NP-4726 (July 1986) and the Seismic Hazard Characterization of 69 Nuclear Plant Sites East of the Rocky Mountains, Lawrence Livermore National Laboratory Model, (Bernreuter et al., 1989). The objective of the CEUS SSC Project is to develop a new seismic source model for the CEUS using a Senior Seismic Hazard Analysis Committee (SSHAC) Level 3 assessment process. The goal of the SSHAC process is to represent the center, body, and range of technically defensible interpretations of the available data, models, and methods. Input to a probabilistic seismic hazard analysis (PSHA) consists of both seismic source characterization and ground motion characterization. These two components are used to calculate probabilistic hazard results (or seismic hazard curves) at a particular site. This report provides a new seismic source model. Results and Findings The product of this report is a regional CEUS SSC model. This model includes consideration of an updated database, full assessment and incorporation of uncertainties, and the range of diverse technical interpretations from the larger technical community. The SSC model will be widely applicable to the entire CEUS, so this project uses a ground motion model that includes generic variations to allow for a range of representative site conditions (deep soil, shallow soil, hard rock). Hazard and sensitivity calculations were conducted at seven test sites representative of different CEUS hazard environments. Challenges and Objectives The regional CEUS SSC model will be of value to readers who are involved in PSHA work, and who wish to use an updated SSC model. This model is based on a comprehensive and traceable process, in accordance with SSHAC guidelines in NUREG/CR-6372, Recommendations for Probabilistic

    The Eastern fence lizard, Sceloporus undulatus, is widely distributed in eastern and central North America, ranging through areas with high levels of Lyme disease, as well as areas where Lyme disease is rare or absent. We studied the potential role of S. undulatus in transmission dynamics of Lyme spirochetes by sampling ticks from a variety of natural hosts at field sites in central New Jersey, and by testing the reservoir competence of S. undulatus for Borrelia burgdorferi in the laboratory. The infestation rate of ticks on fence lizards was extremely low (proportion infested = 0.087, n = 23) compared to that on white footed mice and other small mammals (proportion infested = 0.53, n = 140). Of 159 nymphs that had fed as larvae on lizards that had previously been exposed to infected nymphs, none was infected with B. burgdorferi, compared with 79.9% of 209 nymphs that had fed as larvae on infected control mice. Simulations suggest that changes in the numbers of fence lizards in a natural habitat would have little effect on the infection rate of nymphal ticks with Lyme spirochetes. We conclude that in central New Jersey S. undulatus plays a minimal role in the enzootic transmission cycle of Lyme spirochetes.

    Leprosy was rare in Europe during the Roman period, yet its prevalence increased dramatically in medieval times. We examined human remains, with paleopathological lesions indicative of leprosy, dated to the 6th-11th century AD, from Central and Eastern Europe and Byzantine Anatolia. Analysis of ancient DNA and bacterial cell wall lipid biomarkers revealed Mycobacterium leprae in skeletal remains from 6th-8th century Northern Italy, 7th-11th century Hungary, 8th-9th century Austria, the Slavic Greater Moravian Empire of the 9th-10th century and 8th-10th century Byzantine samples from Northern Anatolia. These data were analyzed alongside findings published by others. M. leprae is an obligate human pathogen that has undergone an evolutionary bottleneck followed by clonal expansion. Therefore M. leprae genotypes and sub-genotypes give information about the human populations they have infected and their migration. Although data are limited, genotyping demonstrates that historical M. leprae from Byzantine Anatolia, Eastern and Central Europe resembles modern strains in Asia Minor rather than the recently characterized historical strains from North West Europe. The westward migration of peoples from Central Asia in the first millennium may have introduced different M. leprae strains into medieval Europe and certainly would have facilitated the spread of any existing leprosy. The subsequent decline of M. leprae in Europe may be due to increased host resistance. However, molecular evidence of historical leprosy and tuberculosis co-infections suggests that death from tuberculosis in leprosy patients was also a factor.

    Full Text Available The main aim of the study was to identify and evaluate the progress of implementation of selected assumptions on sustainability of agriculture in countries of CentralEastern Europe in relation to environmental protection. Data from the input-output balance sheets and the European Environmental Accounts were used to realize the aim of the study. The analysis considered material fl ows to and from agriculture, pollution, and the production and consumption of biomass. The share of the participation of agribusiness sphere I, including mainly services, as well as the fuel, energy and chemical industries, has been increasing in the material infl ows to agriculture in the countries of CentralEastern Europe. This indicates production modernization, associated with a higher load on the environment. The highest emissions of greenhouse gases and air pollutants into the environment per 1,000 euro GDP were recorded in Lithuania, Romania and Latvia. The Czech Republic, Slovenia and Slovakia have the lowest values of emissions. In Latvia, there was no overall reduction in pollution emitted by agriculture in 2008–2012. Emission of these pollutants per 1,000 euro GDP and 1 ha UAA (utilized agricultural area of agricultural land decreased in most countries in the analysis. In EU countries of Central-Eastern Europe, a reduction in direct material input and domestic consumption of biomass from agriculture per one euro of GDP is reported. These changes indicate a decrease in the intensity of use of natural resources (dematerialising economy, which is consistent with the objectives of sustainable development. In countries where agriculture is better developed, the implementation of pro-environmental goals of sustainable development takes place to a greater extent than in countries with lower levels of socio-economic development.

    Full Text Available Background: Promotion of birth preparedness and raising awareness of potential complications is one of the main strategies to enhance the timely utilisation of skilled care at birth and overcome barriers to accessing care during emergencies. Objective: This study aimed to investigate factors associated with birth preparedness in three districts of eastern central Uganda. Design: This was a cross-sectional baseline study involving 2,010 women from Iganga [community health worker (CHW strategy], Buyende (vouchers for transport and services, and Luuka (standard care districts who had delivered within the past 12 months. ‘Birth prepared’ was defined as women who had taken all of the following three key actions at least 1 week prior to the delivery: 1 chosen where to deliver from; 2 saved money for transport and hospital costs; and 3 bought key birth materials (a clean instrument to cut the cord, a clean thread to tie the cord, cover sheet, and gloves. Logistical regression was performed to assess the association of various independent variables with birth preparedness. Results: Only about 25% of respondents took all three actions relating to preparing for childbirth, but discrete actions (e.g. financial savings and identification of place to deliver were taken by 75% of respondents. Variables associated with being prepared for birth were: having four antenatal care (ANC visits [adjusted odds ratio (ORA=1.42; 95% confidence interval (CI 1.10–1.83], attendance of ANC during the first (ORA=1.94; 95% CI 1.09–3.44 or second trimester (ORA=1.87; 95% CI 1.09–3.22, and counselling on danger signs during pregnancy or on place of referral (ORA=2.07; 95% CI 1.57–2.74.

    The yield of bedrock wells in the fractured-bedrock aquifers of the Nashoba terrane and surrounding area, central and eastern Massachusetts, was investigated with analyses of existing data. Reported well yield was compiled for 7,287 wells from Massachusetts Department of Environmental Protection and U.S. Geological Survey databases. Yield of these wells ranged from 0.04 to 625 gallons per minute. In a comparison with data from 103 supply wells, yield and specific capacity from aquifer tests were well correlated, indicating that reported well yield was a reasonable measure of aquifer characteristics in the study area. Statistically significant relations were determined between well yield and a number of cultural and hydrogeologic factors. Cultural variables included intended water use, well depth, year of construction, and method of yield measurement. Bedrock geology, topography, surficial geology, and proximity to surface waters were statistically significant hydrogeologic factors. Yield of wells was higher in areas of granites, mafic intrusive rocks, and amphibolites than in areas of schists and gneisses or pelitic rocks; higher in valleys and low-slope areas than on hills, ridges, or high slopes; higher in areas overlain by stratified glacial deposits than in areas overlain by till; and higher in close proximity to streams, ponds, and wetlands than at greater distances from these surface-water features. Proximity to mapped faults and to lineaments from aerial photographs also were related to well yield by some measures in three quadrangles in the study area. Although the statistical significance of these relations was high, their predictive power was low, and these relations explained little of the variability in the well-yield data. Similar results were determined from a multivariate regression analysis. Multivariate regression models for the Nashoba terrane and for a three-quadrangle subarea included, as significant variables, many of the cultural and

  20. Social security reform in Central and Eastern Europe: variations on a Latin American theme.

    Science.gov (United States)

    Kritzer, B E

    After Chile reformed its social security system in 1981, several other Latin American countries and certain Central and Eastern European (CEE) countries implemented the Chilean model, with some variations: either a single- or multitier system, or with a period of transition to take care of those in the labor force at the time of the change. The single-tier version consists of individual accounts in pension fund management companies. Multi-tier systems retain some form of public program and add mandatory individual accounts. Most of the CEE countries did not want to incur the high transition costs associated with the Chilean model. The switch to a market economy had already strained their economies. Also, the countries' desire to adopt the European Union's Euro as their currency--a move that required a specific debt ceiling--limited the amount of additional debt they could incur. This article describes the CEE reforms and makes some comparisons with the Latin American experience. Most of the CEE countries have chosen a mixed system and have restructured the pay-as-you-go (PAYGO) tier, while the Latin American countries have both single- and multi-tier systems. Some CEE countries have set up notional defined contribution (NDC) schemes for the PAYGO tier in which each insured person has a hypothetical account made up of all contributions during his or her working life. Survivors and disability programs in CEE have remained in the public tier, but in most of the Latin American programs the insured must purchase a separate insurance policy. Issues common to both regions include: Administrative costs are high and competition is keen, which has led to consolidation and mergers among the companies and a large market share controlled by a few companies. Benefits are proportionately lower for women than for men. A large, informal sector is not covered by social security. This sector is apparently much larger in Latin America than in the CEE countries. Issues that are unique

  1. Various origins of clinopyroxene megacrysts from basanites from the eastern part of Central European Volcanic Province

    Clinopyroxene megacrysts up to few centimetres in size occur in Cenozoic alkaline lavas forming the north-eastern part of Central European Volcanic Province in Lower Silesia (SW Poland). The megacrysts occur, among other, in the Miocene basanite from Ostrzyca Proboszczowicka (bulk rock mg# 0.65-0.66) and in that from Lutynia (Pliocene, K-Ar age: 4.56 +/- 0.2 Ma; Birkenmajer et al. 2002; bulk rock mg# 0.64). The megacrysts typically consist of homogeneous core surrounded by patchy and spongy mantle, which is covered by a thin outermost rim of composition similar to that of the groundmass clinopyroxene occurring in the host basanite. The mantles of the megacrysts have been affected by melting, whereas the cores preserve their primary composition. We compare the core parts of megacrysts in the following. The Ostrzyca clinopyroxene megacrysts contain euhedral apatite intergrowths. The clinopyroxene has the composition of Fe-rich diopside (mg# = 0.61 - 0.70), contain significant sodium (to 0.12 a pfu) and are calcium rich (0.89-0.92 a pfu). The Lutynia megacrysts have the composition of augite and diopside (mg# 0.80-0.83). The sodium content is also high (to 0.12 a pfu), but calcium varies from 0.68 to 0.77 a pfu. The REE concentrations for Lutynia (1-10 x PM) are lower relative to Ostrzyca, enriched 10-100 times relative to PM. In both sites the megacrysts are strongly enriched in LREE relative to HREE and TE are characterized by positive Th, La and Ce anomalies, slight negative Sr and Y anomalies and strong Pb anomaly in the PM normalised patterns. The megacrysts from Ostrzyca reveal slight negative Ti and strong positive Zr and Hf anomalies, whereas those Lutynia have negative Zr anomaly and Ti anomaly is absent. Major and trace element composition shows that the megacrysts from Ostrzyca formed as coarse-grained cumulate at significant depth (lower crust?) from the LREE enriched alkaline melt. That melt was very rich in phosphorous which enabled its saturation in

    Desert scrublands comprise the lower to mid-elevation portions of four different ecosystems including the Chihuahuan, Great Basin, Mojave and Sonoran Deserts. Together the area inside their outer boundaries includes over 8% of the surface area of the United States. Despite significant differences in the flora and fauna of these bioregions they all share the common trait of being arid shrub-steppe ecosystems, receiving, on average, less than 254 mm of rain per year. The austere nature of these landscapes belies their significant biodiversity, the amazing behavioral and physiological adaptations of the biota, and the fragility of the ecosystems to human disturbances. For example, the Mojave Desert alone has at least 250 species of ephemeral plants, mostly winter annuals, and up to 90% are endemic.

    The Basu metamorphic complex, surrounded by ophiolitic melanges and intruded by a large volume of undeformed granitoid rocks along the eastern segment of the Bangong-Nujiang suture, holds one of the keys to understanding the pre-Cenozoic tectonic evolution of central Tibet. Zircon U-Pb dating of rocks from the Basu metamorphic complex reveals that meta-igneous rocks yield Early Paleozoic crystallization ages of 500-492 Ma and an Early Jurassic metamorphic age of 173 Ma, and that undeformed granitoid rocks yield crystallization ages of approximately 186-174 Ma. Whole rock geochemical and zircon Lu-Hf isotopic data indicate that the undeformed granitoid rocks originated mainly from partial melting of ancient crustal sources, which may reflect a collisional orogenic setting. 40Ar/39Ar dating of biotite from a sillimanite-garnet-biotite paragneiss shows cooling to 300 ± 50 °C at 165 Ma. These data indicate significant Early Jurassic tectonism, during which most of the Basu metamorphic complex was formed. Furthermore, the age data resemble those of the Amdo metamorphic complex located approximately 500 km to the west along the Bangong-Nujiang suture. Together, these complexes may represent a ;destroyed or unrecognized; block, i.e., the Amdo-Tongka block, which may be the eastern extension of the South Qiangtang terrane. Based on the tectonic outlines of the multiple ophiolitic zones and magmatic belts, we suggest a new archipelago-accretion model that attributes the Early Jurassic tectonism to an arc-continent/micro-continent collision. This model further enables the reconstruction of the eastern Tethyan Ocean and the orogenic processes of central Tibet during the Mesozoic.

    Full Text Available The decision of the Swiss National Bank of giving up the fixed rate of 1,2 Euro/CHF on the 15th of January 2015, a rate established at its admission to the Monetary Economic Union, had consequences on Central and Eastern European countries because a great part of the credits granted were in Swiss francs. In all these countries, the national currencies depreciated and the financial market rates were reduced. Regional banks started to face difficulties regarding the management of the situation and were under the necessity of finding solutions to avoid the risk of not recovering the granted credits. The issue of the Swiss franc appreciation was treated differently by the analysed countries and took into consideration the particularities characteristic to the credits granted in this currency. The present paper aims at emphasising the impact of the Swiss franc appreciation on the Romanian banking system but also the approach of other countries in Central and Eastern Europe in this respect.

    Full Text Available The Current Evolution of Slavic Languages in Central and Eastern Europe in the Context of the EU Multilingualism Policy The respect for and protection of cultural and linguistic diversity have long been guaranteed in various international and European legislative acts. More recently, the European Union has also developed laws aimed at the preservation and promotion of multilingualism. Linguistic diversity has long been seen as an obstacle to the effective functioning of EU institutions. Recently, however, it has been considered as a valuable “heritage” of the EU. In our article, we will present a brief overview of policies promoting multilingualism in Europe, and more specifically, in the EU. Subsequently, we will compare this framework to the changes occurring presently in modern Slavic languages of Central and Eastern Europe. The tendency of these languages towards increased analitism transforms these predominantly synthetic languages into more analytical ones. These conclusions have led us to the following question: What is the current state of modern Slavic languages and how far may their evolution be addressed by policies promoting multilingualism? Our analysis consists of two parts: first, we scrutinised various European legislative acts promoting multilingualism; second, we analysed modern Slavic languages by means of the parallel corpora of chosen languages from the Common Language Resources and Technology Infrastructure project (including UNESCO and EU legislation, etc..

    Although China has experienced rapid economic growth over the past few decades, significant health and nutritional problems remain. Little work has been done to track basic diseases, such as iron-deficiency anemia, so the exact prevalence of these health problems is unknown. The goals of this study were to assess the prevalence of anemia in China and identify individual, household and community-based factors associated with anemia. We used data from the 2009 China Health and Nutrition Survey (CHNS), including the measurement of hemoglobin levels among 7,261 individuals from 170 communities and 7 provinces in central and eastern China. The overall prevalence of anemia was 13.4% using the WHO's blood hemoglobin thresholds (1968). This means in China's more developed central and eastern regions up to 180 million people may be anemic. Some vulnerable subgroups were disproportionately affected by anemia. Seniors (aged 60 years and above) were more likely to be anemic than younger age cohorts, and females had higher anemia prevalence among all age groups except among children aged 7 to 14 years. We found a negative correlation between household wealth and the presence of anemia, suggesting anemia prevalence may decline as China's economy grows. However, the prevalence of anemia was greater in migrant households, which should be experiencing an improved economic status.

    Numerous microcontinents are known to occur in the Central Asian Orogenic Belt (CAOB), one of the largest accretionary orogens and the most significant area of Paleozoic crustal growth in the world. The evolution of the Precambrian crust in these microcontinents is central to understanding the accretionary and collisional tectonics of the CAOB. Here, we present systematic zircon U-Pb dating and Hf isotope studies of Mesoproterozoic gneissic granitoids from the eastern Central Tianshan Arc Terrane (CTA) of the southern CAOB. The investigated intermediate to felsic (SiO2 = 60.48-78.92 wt.%) granitoids belong to the calcic- to calc-alkaline series and usually have pronounced negative Nb, Ta and Ti anomalies, relative enrichments of light rare earth elements (LREEs) and large ion lithophile elements (LILEs) while heavy rare earth elements (HREEs) and high field strength elements (HFSEs) are depleted, revealing typical active continental margin magmatic arc geochemical characteristics. These spatially-distant rocks show consistent zircon U-Pb crystallization ages from ca. 1.45 to 1.40 Ga and thus constitute a previously unknown Mesoproterozoic continental magmatic arc covering hundreds of kilometers in the eastern segment of the CTA. Furthermore the high and mainly positive zircon εHf(t) values between - 1.0 and + 8.6 and the zircon Hf model ages of 1.95 to 1.55 Ga, which are slightly older than their crystallization ages, suggest that they were mainly derived from rapid reworking of juvenile material with a limited input of an ancient crustal component. Therefore, the formation of these granitoids defines an extensive Mesoproterozoic intermediate to felsic, subduction-related intrusive magmatic arc activity that was active from at least 1.45 to 1.40 Ga, involving significant juvenile continental growth in the eastern segment of the CTA. Furthermore the zircon U-Pb and Hf isotopic data challenge the common belief that the CTA was part of the Tarim Craton during Paleo

    There is very little dated evidence on wet periods in the Eastern Desert and Sinai Peninsula of Egypt during the Late Pleistocene and Holocene. To obtain such information, we have studied the petrography, isotope geochemistry and AMS radiocarbon ages of mostly relict tufas deposited by springs draining perched ground water bodies in metamorphic and volcanic rocks. The tufas unconformably overly Precambrian basic igneous rocks (basalt, diabase and gabbro). As the ages of tufa carbonate are frequently older than the true ages of the deposits because of the incorporation of old, 14C-dead carbon, we have dated both the carbonate matrix and insoluble organic material of the tufas. These ages show that the tufas were largely formed during two broad time periods, the most recent from 12,058 to 6678 cal yr BP (African Humid Period), and the other from ˜31,200-22,500 cal yr BP, with preferential growth during the coldest times of this period namely during Heinrich Events 2 and 3 (H2 and H3) and the Last Glacial Maximum (LGM). The time span between 19,000-9000 cal yr BP, including the YD and H1, appears to have been relatively more arid than the earlier LGM or H2 periods or the later Holocene. The Late Pleistocene tufas are depleted in 18O relative to the Holocene tufas and were deposited at a lower temperature (˜14.0°-20.8 °C vs. 18.4°-23.4 °C). We believe that the Holocene tufas in the Sinai were formed by rainfall from the Mediterranean and those in the southern part of the Eastern Desert by African monsoon rainfall derived from the Red Sea-Gulf of Aden and Indian Ocean. In contrast, the moisture that fed the Late Pleistocene tufas, which are depleted in 18O relative to Holocene deposits, and progressively depleted from north to south, was probably brought by the Westerlies from the Atlantic-Mediterranean Sea when the Westerly circulation was pushed southwards during the coldest periods of the Late Pleistocene. Periods of tufa deposition correlate with major

    According to the relationship between urbanization development and industrialization development since the opening up and reform of China,the quantitative analysis of I/U and N/U is conducted.The results show that the overall level of China’s urbanization lags behind that of the industrialization,and this phenomenon of lag tends to dwindle.In 2003,the relationship between China’s urbanization and industrialization was most balanced,but after 2003,the phenomenon of urbanization lagging behind industrialization tends to distend gradually again;being that the development of urbanization is influenced by natural basis and policy,different regions have different cases.In the eastern and central region,the urbanization lags behind industrialization;in the northeastern region,the urbanization preponderate over industrialization;in the western region,the level of urbanization is not high,but it develops along with the industrialization in tandem.The regional difference of urbanization and industrialization requires that different should implement different policies.The eastern region still has great developmental space,and it should implement the strategy of urbanization as soon as possible;on the basis of expanding the current urban scale and improving quality,the central region should quicken the development of central cities;the western region should choose the path of concentrated-type urbanization;the three northeastern provinces should give priority to improving the quality of local industrialization vigorously and promoting the rapid upgrade of industrial structure,so as to propel the balanced development of urbanization and industrialization.

  14. Vertical structure variability and equatorial waves during central Pacific and eastern Pacific El Ninos in a coupled general circulation model

    Recent studies report that two types of El Nino events have been observed. One is the cold tongue El Nino or Eastern Pacific El Nino (EP El Nino), which is characterized by relatively large sea surface temperature (SST) anomalies in the eastern Pacific, and the other is the warm pool El Nino (a.k.a. 'Central Pacific El Nino' (CP El Nino) or 'El Nino Modoki'), in which SST anomalies are confined to the central Pacific. Here the vertical structure variability of the periods during EP and CP is investigated based on the GFDL{sub C}M2.1 model in order to explain the difference in equatorial wave dynamics and associated negative feedback mechanisms. It is shown that the mean stratification in the vicinity of the thermocline of the central Pacific is reduced during CP El Nino, which favours the contribution of the gravest baroclinic mode relatively to the higher-order slower baroclinic mode. Energetic Kelvin and first-meridional Rossby wave are evidenced during the CP El Nino with distinctive amplitude and propagating characteristics according to their vertical structure (mostly first and second baroclinic modes). In particular, the first baroclinic mode during CP El Nino is associated to the ocean basin mode and participates to the recharge process during the whole El Nino cycle, whereas the second baroclinic mode is mostly driving the discharge process through the delayed oscillator mechanism. This may explain that the phase transition from warm to neutral/cold conditions during the CP El Nino is delayed and/or disrupted compared to the EP El Nino. Our results have implications for the interpretation of the variability during periods of high CP El Nino occurrence like the last decade. (orig.)

    The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to "sky islands" of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.

    We present here a reappraisal of the tectonic setting, stratigraphy and palaeogeography of the central part of the Sivas Basin from Palaeocene to late Miocene. The Sivas Basin is located in the collision zone between the Pontides (southern Eurasia) and Anatolia (a continental block rifted from Gondwana). The basin overlies ophiolites that were obducted onto Anatolia from Tethys to the north. The Central Anatolian Crystalline Complex (CACC) experienced similar ophiolite obduction during Campanian time, followed by exhumation and thrusting onto previously emplaced units during Maastrichtian time. To the east, crustal extension related to exhumation of the CACC created grabens during the early Tertiary, including the Sivas Basin. The Sivas Basin underwent several tectonic events during Paleogene-Neogene. The basin fill varies, with several sub-basins, each being characterised by a distinctive sequence, especially during Oligocene and Miocene. Evaporite deposition in the central part of the basin during early Oligocene was followed by mid-late Oligocene fluvio-lacustrine deposition. The weight of overlying fluvial sediments triggered salt tectonics and salt diapir formation. Lacustrine layers that are interbedded within the fluviatile sediments have locally yielded charophytes of late Oligocene age. Emergent areas including the pre-existing Sivas Basin and neighbouring areas were then flooded from the east by a shallow sea, giving rise to a range of open-marine sub-basins, coralgal reef barriers and subsiding, restricted-marine sub-basins. Utilising new data from foraminifera, molluscs, corals and nannoplankton, the age of the marine transgression is reassessed as Aquitanian. Specifically, age-diagnostic nannoplankton assemblages of classical type occur at the base of the transgressive sequence. However, classical stratigraphic markers have not been found within the planktic foraminiferal assemblages, even in the open-marine settings. In the restricted-marine sediments

    In Eastern Africa, small-scale pig keeping has emerged as a popular activity to generate additional household income. Infections of pigs with gastrointestinal helminths can limit production output, increase production costs, and pose zoonotic risks. A cross-sectional, community-based study in three districts in Eastern and Central Uganda examined the prevalence of gastrointestinal helminthes and associated risk factors in 932 randomly sampled pigs. Using the combined sedimentation-flotation method, 61.4 % (58.2-64.5 %, 95 % confidence interval [CI]) tested positive for one or more gastrointestinal helminths, namely, strongyles (57.1 %, 95 % CI), Metastrongylus spp. (7.6 %, 95 % CI), Ascaris suum (5.9 %, 95 % CI), Strongyloides ransomi (4.2 %, 95 % CI), and Trichuris suis (3.4 %, 95 % CI). Coccidia oocysts were found in 40.7 % of all pigs sampled (37.5-44.0 %, 95 % CI). Significant differences across the three districts were observed for the presence of A. suum (p pig pens (p ≤ 0.05, odds ratio [OR] = 0.667) and the routine use of disinfectants (p ≤ 0.05, OR = 0.548).

    Full Text Available Abstract Background The high cardiovascular mortality in Eastern Europe has often been attributed to poor diet, but individual-level data on nutrition in the region are generally not available. This paper describes the methods of dietary assessment and presents preliminary findings on food and nutrient intakes in large general population samples in Russia, Poland and the Czech Republic. Methods The HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe study examined random samples of men and women aged 45-69 years at baseline in Novosibirsk (Russia, Krakow (Poland and six Czech urban centres in 2002-2005. Diet was assessed using a food frequency questionnaire (at least 136 items; complete dietary information was available for 26,870 persons. Results Total energy intakes among men ranged between 8.7 MJ in the Czech sample and 11.7 MJ in the Russian sample, while among women, energy intakes ranged between 8.2 MJ in the Czech sample and 9.8 MJ in the Russian sample. A Healthy Diet Indicator (HDI, ranging from a score of 0 (lowest to 7 (highest, was developed using the World Health Organisation's (WHO guidelines for the prevention of chronic diseases. The mean HDI scores were low, ranging from 1.0 (SD = 0.7 among the Polish subjects to 1.7 (SD = 0.8 among the Czech females. Very few subjects met the WHO recommended intakes for complex carbohydrates, pulses or nuts; intakes of saturated fatty acids, sugar and protein were too high. Only 16% of Polish subjects met the WHO recommendation for polyunsaturated fat intake. Consumption of fruits and vegetables was lower than recommended, especially among those Russian subjects who were assessed during the low intake season. Fewer than 65% of subjects consumed adequate amounts of calcium, magnesium and potassium, when compared with the United Kingdom's Reference Nutrient Intake. Conclusion This first large scale study of individual-based dietary intakes in the general population in Eastern

    Livestock ranching is one of the main productive activities in arid regions of the world. Grazing pro-duces changes in animal as well as plant communities (e.g. richness, abundance and species dominance rela-tionships). Ants are good biological indicators due to the environmental fidelity of some of their community pa-rameters. We described the functional structure of the ant community in the central Monte of Mendoza, Argentina, and examined the effect of grazing using richness, diversity and the functional group scheme. We used pitfall traps to sample ants at a reserve with 30-year cattle exclusion and at an adjacent ranch. Eleven of the 27 recorded spe-cies showed significant differences in their abundance and two species were absent at the ranch. While richness and diversity did not reflect these differences, functional groups did. Hot Climate Specialists were more abundant at the ranch while Cryptic Species and Generalized Myrmicinae increased at the reserve. This study supports the utility of the functional group scheme to study the effects of grazing disturbance in ant communities of arid regions.

    Full Text Available The study has analyzed the relationship between youth unemployment and economic growth, in the context of Okun law, by using new generation panel data analysis and cointegration tests. In this study, 18 Central and Eastern European country have been selected as subject matter whose youth unemployment rate is above the EU-28 average (25 % for the period 2006-2012. The results show that, if youth unemployment is quite severe; even an exclusive economic growth will not be enough to reduce the youth unemployment rate in the country. It is recommended that the global and country-specific policies which are effective, result-driven on youth (Un employment and labour market issues, should be developed. This study is expected to make a significant contribution to the literature on unemployment and social conflict.

    Full Text Available The research paper is focused on the analysis of two ways of strengthening the regional integration in the Central and Eastern Europe – through the Cohesion policy instruments and cooperation among stock exchanges. Substantial benefits from the regional integration through cohesion policy include economic and social prosperity, political understanding. It should be further intensified, as it contributes to reduce regional disparities, exchange knowledge and best practices, ensure economic development. On the other hand, the deepening intra-regional cooperation among CEE stock exchanges leads to quantitative and qualitative changes in the course of their consolidation. Some assumptions are reached regarding expected changes on the Bulgarian capital market in the course of intensifying its intra-regional integrational links to CEE capital markets in conformity with set strategic priorities.

    We describe a new species of Pristimantis from the humid forests on the eastern flank of the northern Cordillera Central in Colombia (6º 23' 19.3554" N, 75º 1' 24.0594" W; ca. 1150 m.a.s.l.). Pristimantis jaguensis sp. nov. is characterized by an extraordinary variation in color and is readily distinguished from congeneric species by lacking nuptial pads, discoidal fold and conical calcar tubercles; flanks and belly white to cream without blotches as well as iris yellow ocher to copper with thick brown reticulation and cream sclera. Molecular phylogenetic analyses recovered the new species in a clade with species mostly distributed in Ecuador. Our finding suggests that new taxa can still be discovered in the Middle Magdalena River valley of Colombia despite the extensive sampling this region has received during the last decades.

    Liza bandialensis Diouf 1991 is redescribed because previous descriptions have not been in well-distributed publications and have lacked sufficient detail or reference to voucher specimens. The description provided here is based on specimens from the Sine Saloum estuary, Senegal (West Africa), from where the species was originally described. The distinctness of the species is confirmed both by meristic and molecular criteria. L. bandialensis presents a unique combination of characters with a low number of scales in the longitudinal series (32-33), 10.5-12 transverse scale rows, and distinctly yellowish dorsal, anal, and caudal fins. The currently known distribution of L. bandialensis includes coastal waters of Senegal, Gambia and Guinea Bissau. Finally, we provide a morphological identification key for the sixteen species of Mugilidae species occurring along the eastern central Atlantic coast of Africa.

    Full Text Available The past decade has seen significant political, economic and social changes in several Central and Eastern European (CEE countries. The reasons for the most important transformation processes were the EU membership and the global recession of the late 2000’s. Our study focuses on the effects of these circumstances on people’s work-related values and attitudes. This longitudinal comparative analysis is based on the results of the European Values Study of 1999/2000 and 2008/2009. Our aim is to detect the priorities that determine employees' attitudes to work in ten CEE countries of the EU. Slovenia and Hungary will be paid special attention since these two countries seem not to be followingthe main direction of changes found in the CEE region.

    Primary immunodeficiency disorders are a recognized public health problem worldwide. The prototype of these conditions is X-linked agammaglobulinemia (XLA) or Bruton's disease. XLA is caused by mutations in Bruton's tyrosine kinase gene (BTK), preventing B cell development and resulting in the almost total absence of serum immunoglobulins. The genetic profile and prevalence of XLA have not previously been studied in Eastern and Central European (ECE) countries. We studied the genetic and demographic features of XLA in Belarus, Croatia Hungary, Poland, Republic of Macedonia, Romania, Russia, Serbia, Slovenia, and Ukraine. We collected clinical, immunological, and genetic information for 122 patients from 109 families. The BTK gene was sequenced from the genomic DNA of patients with a high susceptibility to infection, almost no CD19(+) peripheral blood B cells, and low or undetectable levels of serum immunoglobulins M, G, and A, compatible with a clinical and immunological diagnosis of XLA. BTK sequence analysis revealed 98 different mutations, 46 of which are reported for the first time here. The mutations included single nucleotide changes in the coding exons (35 missense and 17 nonsense), 23 splicing defects, 13 small deletions, 7 large deletions, and 3 insertions. The mutations were scattered throughout the BTK gene and most frequently concerned the SH1 domain; no missense mutation was detected in the SH3 domain. The prevalence of XLA in ECE countries (total population 145,530,870) was found to be 1 per 1,399,000 individuals. This report provides the first comprehensive overview of the molecular genetic and demographic features of XLA in Eastern and Central Europe.

    We have studied the recent to current deformation in Iran and especially Central-Eastern Iran by tightly combining tectonic and GPS analyses. Based on morphotectonic analyses of satellite images, we have identified and mapped the major active faults that dissect the entire ≈ 4500 km x 2500 km2 region that extends from Eastern Turkey to Western Afghanistan/Pakistan and hence encompasses Iran, emphasizing their large-scale organization and kinematic relationships. Doing so, we have identified the major fault systems that control the tectonics of Iran, especially in its central-eastern part. We have also analyzed the 11 years GPS record on the 92 stations deployed in central-eastern Iran in the framework of the Iranian-French collaboration. The GPS analysis reveals that all major faults identified as seismogenic in central-eastern Iran are indeed currently active and slipping at fast rates. The northerly-trending East Lut, West Lut, Kuhbanan, Anar and Deshir faults have a current right-lateral slip rate of 5.7 ± 0.9, 4.7 ± 1.7, 2.3 ± 1.9, 2.7 ± 1.3 and 0.5 ± 0.2 mm/yr, respectively, while the ≈ EW-trending Doruneh and Sedeh faults have a left-lateral current slip rate of 3.1 ± 1.8 and 1.7 ± 0.2 mm/yr, respectively. The large regions bounded by the northerly-striking faults behave as fairly rigid blocks that are all found to move towards both the N13°E ARA-EUR convergence direction and the WNW, at fast rates, in the range 6.5-12.5 and 1-5 mm/yr, respectively. Combined with the available data on the studied faults, our tectonic and geodetic results suggest that a bookshelf faulting strain transfer mechanism has been and is still operating in central-eastern Iran. The coeval dextral motion of the two major, overlapping, North Anatolian-Main Recent and Caucasus-Kopeh Dagh-Herat fault lines that embrace central-eastern Iran, induces a large-scale regional sinistral shear on either side of the region, which forces the northerly-trending right-lateral faults and

    The U.S. Geological Survey (USGS) has produced a 1-year seismic hazard forecast for 2016 for the Central and Eastern United States (CEUS) that includes contributions from both induced and natural earthquakes. The model assumes that earthquake rates calculated from several different time windows will remain relatively stationary and can be used to forecast earthquake hazard and damage intensity for the year 2016. This assessment is the first step in developing an operational earthquake forecast for the CEUS, and the analysis could be revised with updated seismicity and model parameters. Consensus input models consider alternative earthquake catalog durations, smoothing parameters, maximum magnitudes, and ground motion estimates, and represent uncertainties in earthquake occurrence and diversity of opinion in the science community. Ground shaking seismic hazard for 1-percent probability of exceedance in 1 year reaches 0.6 g (as a fraction of standard gravity [g]) in northern Oklahoma and southern Kansas, and about 0.2 g in the Raton Basin of Colorado and New Mexico, in central Arkansas, and in north-central Texas near Dallas. Near some areas of active induced earthquakes, hazard is higher than in the 2014 USGS National Seismic Hazard Model (NHSM) by more than a factor of 3; the 2014 NHSM did not consider induced earthquakes. In some areas, previously observed induced earthquakes have stopped, so the seismic hazard reverts back to the 2014 NSHM. Increased seismic activity, whether defined as induced or natural, produces high hazard. Conversion of ground shaking to seismic intensity indicates that some places in Oklahoma, Kansas, Colorado, New Mexico, Texas, and Arkansas may experience damage if the induced seismicity continues unabated. The chance of having Modified Mercalli Intensity (MMI) VI or greater (damaging earthquake shaking) is 5–12 percent per year in north-central Oklahoma and southern Kansas, similar to the chance of damage caused by natural earthquakes

    A Muztagata ice core recovered at 7010 m altitude in East Pamirs provides a Pb concentration record from 1955 to 2000. The result reveals increasing Pb concentrations from 1955 to 1993, with two Pb concentration peaks in 1980 and 1993. After 1993, Pb concentrations in ice core show an obviously declining trend. Analysis shows that the lead in the Muztagata ice core mainly came from anthropogenic emissions from countries in Central Asia, while the local emission had little contribution.

    Previously undocumented late Eocene diatomaceous sediments are present near Fundo Desbarrancado (FD) in southern Peru. These sediments are similar to Miocene diatomite from the same area but, unlike the Miocene diatomite, the FD sediments contain cherty layers, are enriched in CaCO/sub 3/, have a diverse and abundant radiolarian fauna, and possess varved-massive and millimeter- and meter-scale biogenic-terrigenous alternations. The FD sediments are part of an Eocene sequence that includes the clastic sediments of the Paracas Formation, and they are correlative to the Chira Formation of northern Peru. The Paleogene biogenic sediments of western South America show that coastal upwelling developed in the eastern Pacific before the latest Eocene, argue for the existence of a proto-Humboldt current at this time, and suggest that the terminal Eocene event was the culmination of gradual changes and not a catastrophic event at the Eocene/Oligocene boundary.

    Desert tortoise (Gopherus agassizii) populations have experienced precipitous declines resulting from the cumulative impact of habitat loss, and human and disease-related mortality. Evaluation of hematologic and biochemical responses of desert tortoises to physiologic and environmental factors can facilitate the assessment of stress and disease in tortoises and contribute to management decisions and population recovery. The goal of this study was to obtain and analyze clinical laboratory data from free-ranging desert tortoises at three sites in the Mojave Desert (California, USA) between October 1990 and October 1995, to establish reference intervals, and to develop guidelines for the interpretation of laboratory data under a variety of environmental and physiologic conditions. Body weight, carapace length, and venous blood samples for a complete blood count and clinical chemistry profile were obtained from 98 clinically healthy adult desert tortoises of both sexes at the Desert Tortoise Research Natural area (western Mojave), Goffs (eastern Mojave) and Ivanpah Valley (northeastern Mojave). Samples were obtained four times per year, in winter (February/March), spring (May/June), summer (July/August), and fall (October). Years of near-, above- and below-average rainfall were represented in the 5 yr period. Minimum, maximum and median values, and central 95 percentiles were used as reference intervals and measures of central tendency for tortoises at each site and/or season. Data were analyzed using repeated measures analysis of variance for significant (P < 0.01) variation on the basis of sex, site, season, and interactions between these variables. Significant sex differences were observed for packed cell volume, hemoglobin concentration, aspartate transaminase activity, and cholesterol, triglyceride, calcium, and phosphorus concentrations. Marked seasonal variation was observed in most parameters in conjunction with reproductive cycle, hibernation, or seasonal

    2010-01-01

    Based on an analysis of the present geo-temperature field and the thermal conductivity (K) of 62 samples from the central-south area of the Huaibei coalfield in eastern China, we calculated the heat flow and plotted its distribution map. The results show that the average heat flow in the research area is about 60 mW/m2. It is different from other major energy basins in the North China Plate, but has close relationship with the regional geology and the deep geological setting. The heat flow is comparatively higher in the southeastern, central, and northwestern areas than in the northeastern and southwestern areas. The geo-temperature distribution map of the bottom interface of the Permian coal measure was drawn by calculating its embedding depth and geo-temperature gradients. Finally, the present gas generation condition of the Permian coal measure is discussed by associating with the temperature condition, the vitrinite reflectance (Ro), the metamorphism of coal and tectonic-burial evolution. The study indicates all present characters of the Permian coal measure, such as lower present temperature, higher Ro value, middle-high rank coals, and uplift and extension events after the coal measure sediment, are favorable for the generation of secondary biogenic gas, but not thermogenic gas or primary biogenic gas.

    In recent years, an increasing number of surveys have definitively confirmed the seasonal presence of fin whales (Balaenoptera physalus) in highly productive regions of the Mediterranean Sea. Despite this, very little is yet known about the routes that the species seasonally follows within the Mediterranean basin and, particularly, in the Ionian area. The present study assesses for the first time fin whale acoustic presence offshore Eastern Sicily (Ionian Sea), throughout the processing of about 10 months of continuous acoustic monitoring. The recording of fin whale vocalizations was made possible by the cabled deep-sea multidisciplinary observatory, “NEMO-SN1”, deployed 25 km off the Catania harbor at a depth of about 2,100 meters. NEMO-SN1 is an operational node of the European Multidisciplinary Seafloor and water-column Observatory (EMSO) Research Infrastructure. The observatory was equipped with a low-frequency hydrophone (bandwidth: 0.05 Hz–1 kHz, sampling rate: 2 kHz) which continuously acquired data from July 2012 to May 2013. About 7,200 hours of acoustic data were analyzed by means of spectrogram display. Calls with the typical structure and patterns associated to the Mediterranean fin whale population were identified and monitored in the area for the first time. Furthermore, a background noise analysis within the fin whale communication frequency band (17.9–22.5 Hz) was conducted to investigate possible detection-masking effects. The study confirms the hypothesis that fin whales are present in the Ionian Sea throughout all seasons, with peaks in call detection rate during spring and summer months. The analysis also demonstrates that calls were more frequently detected in low background noise conditions. Further analysis will be performed to understand whether observed levels of noise limit the acoustic detection of the fin whales vocalizations, or whether the animals vocalize less in the presence of high background noise.

    Full Text Available We studied representative samples from a peridotite body situated NE of Sedlice village within the Central- Carpathian Paleogene sediments in the Central Western Carpathians. The relationship of the peridotite to the surrounding Paleogene sediments is not clear. The fractures of the brecciated peridotite margin are healed with secondary magnesite and calcite. On the basis of the presented bulk-rock and electron microprobe data, the wt. % amounts of mineral phases were calculated. Most of calculated “modal” compositions of this peridotite corresponds to harzburgites composed of olivine (∼70-80 wt. %, orthopyroxene (∼17-24 wt. %, clinopyroxene ( < 5 wt. % and minor spinel ( < 1 wt. %. Harzburgites could originate from lherzolitic protoliths due to a higher degree of partial melting. Rare lherzolites contain porphyroclastic 1-2 mm across orthopyroxene (up to 25 wt. %, clinopyroxene (∼ 5-8 wt. % and minor spinel ( < 0.75 wt. %. On the other hand, rare, olivine-rich dunites with scarce orthopyroxene porphyroclasts are associated with harzburgites. Metamorphic mineral assemblage of low-Al clinopyroxene (3, tremolite, chrysotile, andradite, Cr-spinel to chromite and magnetite, and an increase of fayalite component in part of olivine, indicate low-temperature metamorphic overprint. The Primitive Mantle normalized whole-rock REE patterns suggest a depleted mantle rock-suite. An increase in LREE and a positive Eu anomaly may be consequence of interactive metamorphic fluids during serpentinization. Similar rocks have been reported from the Meliatic Bôrka Nappe overlying the Central Western Carpathians orogenic wedge since the Late Cretaceous, and they could be a potential source of these peridotite blocks in the Paleogene sediments.

    Full Text Available The transition from socialist redistributive economy to capitalist markets has proved to be a rockier road that anticipated. The degree and character of difficulties that the countries faced during the transition depended on the nature of the pathways taken. In this paper I distinguish three major trajectories various countries followed: Central European neo-liberalism; post USSR neo-patrimonial regime and the East Asian (Chinese and Vietnamese transformation from below. Rather than distinguishing the “right way” from the “wrong way” I explore what the different costs and benefits of the various pathways were at various stages of the transformation.

  8. Contrasting the eastern Pacific El Niño and the central Pacific El Niño: process-based feedback attribution

    This paper examines the roles of radiative and non-radiative air-sea coupled thermodynamic processes in modifying sea surface temperature (SST) anomalies driven by (air-sea coupled) oceanic dynamic processes, focusing on their contributions to the key differences between the eastern Pacific (EP) El Niño and the central Pacific (CP) El Niño. The attribution is achieved by decomposing SST anomalies into partial temperature anomalies due to individual processes using a coupled atmosphere-surface climate feedback-response analysis method. Oceanic processes induce warming from the central to the eastern equatorial Pacific and cooling over the western basin with a maximum warming center in the central Pacific for both types of El Niño. The processes that act to oppose the oceanic process-induced SST anomalies are surface latent heat flux, sensible heat flux, cloud, and atmospheric dynamic feedbacks, referred to as negative-feedback processes. The cooling due to each of the four negative-feedback processes is the strongest in the region where the initial warming due to oceanic processes is the largest. Water-vapor feedback is the sole process that acts to enhance the initial warming induced by oceanic processes. The increase in atmospheric water vapor over the eastern Pacific is much stronger for the EP El Niño than for the CP El Niño. It is the strong water-vapor feedback over the eastern Pacific and the strong negative feedbacks over the central equatorial Pacific that help to relocate the maximum warming center from the central Pacific to the eastern basin for the EP El Niño.

    Full Text Available The study was based on data collected from nine stations of the Institute of Meteoro­logy and Water Management in central-eastern Poland (1971-2005 concerning monthly precipitation total and mean monthly air temperature during the vegetation period of early potatoes (April-July. Optimal precipitation for early potato was calculated according to the Klatt indexes for medium cohesive and light soils in the successive months of the vegetation period. Rainfall deficit and excess rainfall were determined based on differences between monthly precipitation totals recorded in the years of the study and values considered to be optimal. It was found that the frequency of rainfall deficit during vegetation of early potato in each analysed location both for medium cohesive soil and for light soil exceeded the frequency of its excess. The greatest mean monthly rainfall deficit from the multiannual period in the vegetation season of early potato in all the analysed locations and for both soil types was recorded in June, while excess rainfall was observed in July. Lower values of standard deviation for rainfall deficit were calculated in the case of light soil than medium cohesive soil, while an opposite dependence was recorded for excess rainfall. The risk for early potato plantations on light soil was connected with frequent extreme deficits. They were observed most often in the south-eastern part of the study area, while they were rarest in the belt from Pułtusk towards Szepietowo. Values of the slope of the trend lines were low for all the weather stations and most of them were statistically non-significant. However, all values concerning rainfall deficit were negative, which indicates its slight increase from year to year. A significant trend for changes in rainfall deficit was observed only in Włodawa and Siedlce, while for excess rainfall it was found in Szepietowo and Białowieża.

    Using in situ data collected during 1992-1997, under the Indian programme of Joint Global Ocean Flux Study (JGOFS), we show that the biological productivity of the Arabian Sea is tightly coupled to the physical forcing mediated through nutrient availability. The Arabian Sea becomes productive in summer not only along the coastal regions of Somalia, Arabia and southern parts of the west coast of India due to coastal upwelling but also in the open waters of the central region. The open waters in the north are fertilized by a combination of divergence driven by cyclonic wind stress curl to the north of the Findlater Jet and lateral advection of nutrient-rich upwelled waters from Arabia. Productivity in the southern part of the central Arabian Sea, on the other hand, is driven by advection from the Somalia upwelling. Surface cooling and convection resulting from reduced solar radiation and increased evaporation make the northern region productive in winter. During both spring and fall inter-monsoons, this sea remains warm and stratified with low production as surface waters are oligotrophic. Inter-annual variability in physical forcing during winter resulted in one-and-a-half times higher production in 1997 than in 1995.

    Single grain detrital thermochronology (40Ar/39Ar white mica, zircon fission track and Lu-Hf analysis) of Eocene, Oligocene and Miocene sedimentary rocks from the Central Myanmar Basin permits the identification of tectonothermal events in the source areas, and an understanding of how exhumation histories and changing provenance are related to the palaeogeography of the West Burma block during India-Asia collision. Robinson et al. (2014) used detrital zircon U-Pb and Lu-Hf isotopic analysis to show that Eocene and Oligocene sedimentary rocks were primarily sourced from the Gangdese magmatic arc that lies exclusively within the southern Lhasa terrane, and that the Yarlung Tsangpo and Irrawaddy River were connected at this time. Detrital thermochronology reveal these Paleogene deposits contain broadly distributed, mainly pre-Himalayan 40Ar/39Ar white mica cooling ages, reflecting the contribution from multiple source areas with a cooling history that is similar to the Lhasa terrane. A distinct change in provenance to a single, sustained source area during deposition of the Miocene units is recorded by a white mica 40Ar/39Ar cooling age peak of 37 Ma and a lesser peak of 17 - 21 Ma that is also observed in detrital zircon fission track age data. These two age peaks, 37 Ma and 17 - 21 Ma, likely reflect an initial period of crustal thickening, metamorphism and exhumation in the southern Mogok Metamorphic Belt, and a later phase of exhumation associated with deformation in the eastern syntaxis and the onset of extension in Myanmar and other parts of SE Asia. The latter events are also associated with the disconnection of the Yarlung Tsangpo from the Irrawaddy River around 18 Ma (Robinson et al., 2014). The combined dataset provides constraints on the position and movement of the West Burma block from the Late Eocene to Early Miocene, supports an Oligocene (~37 Ma) age for the timing of India-West Burma-Sibumasu coupling, and an Early Miocene age for extension

    Full Text Available During theeconomic recession periods, gold investments seem to become very importantbecause gold is considered a means to preserve the investment value. Gold has also maintained thisfeature during the financial and economic crisis that occurred at the end of theyear 2007. Althoughthe inflation rate has recorded significant increases, the investment in gold has kept its value becausethe price of gold has increased. After the beginning of the financial and economic crisis the price ofgold has also recorded a significant increase in volatility. The aims of this study focus on thecomparative analysis of the gold price cycles and the stock market cycles in the Central and EastEurope as well as the determination of the return of gold investment on the return and risk of stockmarkets in these countries. The results obtained confirm that both the return and the risk in some ofthe stock markets under analysis are influenced by the return of gold investment.

    Climate, behavior, ecology, and oceanography shape patterns of biodiversity in marine faunas in the absence of obvious geographic barriers. Marine turtles are an example of highly migratory creatures with deep evolutionary lineages and complex life histories that span both terrestrial and marine environments. Previous studies have focused on the deep isolation of evolutionary lineages (>3 mya) through vicariance; however, little attention has been given to the pathways of colonization of the eastern Pacific and the processes that have shaped diversity within the most recent evolutionary time. We sequenced 770 bp of the mtDNA control region to examine the stock structure and phylogeography of 545 green turtles from eight different rookeries in the central and eastern Pacific. We found significant differentiation between the geographically separated nesting populations and identified five distinct stocks (F ST = 0.08-0.44, P Chelonia mydas form a monophyletic group containing 3 subclades, with Hawaii more closely related to the eastern Pacific than western Pacific populations. The split between sampled central/eastern and western Pacific haplotypes was estimated at around 0.34 mya, suggesting that the Pacific region west of Hawaii has been a more formidable barrier to gene flow in C. mydas than the East Pacific Barrier. Our results suggest that the eastern Pacific was colonized from the western Pacific via the Central North Pacific and that the Revillagigedos Islands provided a stepping-stone for radiation of green turtles from the Hawaiian Archipelago to the eastern Pacific. Our results fit with a broader paradigm that has been described for marine biodiversity, where oceanic islands, such as Hawaii and Revillagigedo, rather than being peripheral evolutionary "graveyards", serve as sources and recipients of diversity and provide a mechanism for further radiation.

    Previous research on trichinellosis in Africa focused on isolating Trichinella from wildlife while the role of domestic pigs has remained highly under-researched. Pig keeping in Uganda is historically recent, and evidence on zoonotic pig diseases, including infection with Trichinella species, is scarce. A cross-sectional survey on Trichinella seroprevalence in pigs was conducted in three districts in Central and Eastern Uganda from April 2013 to January 2015. Serum from a random sample of 1125 pigs from 22 villages in Eastern and Central Uganda was examined to detect immunoglobulin G (IgG) against any Trichinella spp. using a commercially available ELISA based on excretory-secretory antigen. ELISA positive samples were confirmed using Western Blot based on somatic antigen of Trichinella spiralis as recommended in previous validation studies. Diaphragm pillar muscle samples (at least 5 g each) of 499 pigs from areas with high ELISA positivity were examined using the artificial digestion method. Overall, 78 of all 1125 animals (6.9%, 95% CI: 5.6–8.6%) tested positive for antibodies against Trichinella spp. in the ELISA at significantly higher levels in Kamuli district compared to Masaka and Mukono districts. Thirty-one percent of the ELISA positive samples were confirmed IgG positive by the Western Blot leading to an overall seroprevalence of 2.1% (95% CI: 1.4–3.2%). The large proportion of ELISA positive samples that could not be confirmed using Western blot may be the result of cross-reactivity with other gastrointestinal helminth infections or unknown host-specific immune response mechanisms in local pig breeds in Uganda. Attempts to isolate muscle larvae for species determination using the artificial digestion method were unsuccessful. Due to the large number of muscle samples examined we are confident that even if pigs are infected, the larval burden in pork is too low to pose a major risk to consumers of developing trichinellosis. This was the first large

    The Precambrian basement of Egypt is part of the Red Sea Mountains and represents the north-western part of the Arabian-Nubian Shield (ANS). Five volcanic sections are exposed in the Egyptian basement complex, namely El Kharaza, Monqul, Abu Had, Mellaha and Abu Marwa. They are located in the north Eastern Desert (ED) of Egypt and were selected for petrological and geochemical studies as they represent the Dokhan volcanics. The volcanics divide into two main pulses, and each pulse was frequently accompanied by deposition of immature molasse type sediments, which represent a thick sequence of the Hammamat group in the north ED. Compositionally, the rocks form a continuum from basaltic andesite, andesite, dacite (lower succession) to rhyodacite and rhyolite (upper succession), with no apparent compositional gaps. These high-K calc-alkaline rocks have strong affinities to subduction-related rocks with enriched LILEs (Rb, Ba, K, Th, Ce) relative to high field strength elements (Nb, Zr, P, Ti) and negative Nb anomalies relative to NMORB. The lower succession displays geochemical characteristics of adakitic rocks with SiO2 >53 wt%, Al2O3 >15 wt%, MgO >2.5 wt%, Mg# >49, Sr >650 ppm, Y 25 ppm, Cr >50 ppm and Sr/Y >42.4. They also have low Nb, Rb and Zr compared to the coexisting calc-alkaline rhyodacites and rhyolites. The highly fractionated rhyolitic rocks have strong negative Eu anomalies and possess the geochemical characteristics of A-type suites. Trace element geochemical signatures indicate a magma source consistent with post-collisional suites that retain destructive plate signatures associated with subduction zones. The adakitic rocks in the northern ANS are generated through partial melting of delaminated mafic lower crust interacting with overlying mantle-derived magma. The Dokhan volcanics were likely generated by a combination of processes, including partial melting, crystal fractionation and assimilation.

    Different particle size parameters have been investigated in this study in order to distinguish the characteristics of different dune morphologies in the Eastern Saudi Arabia. Sand samples were collected from various environments including: the stoss, lee, crest and interdune sides of the inland dunes and foreshore; berm; backshore and backdune of the coastal dunes. Statistical parameters reveal that the majority of inland dune samples are dominated by well sorted fine sand whereas coastal dune samples are mainly dominated by very coarse to medium sand, ranging from well sorted to moderately sorted with a low percentage of silt and clay. The presence of relatively coarser grains in the coastal dunes might be explained by continuous wind deflation along the coast together with wave and tidal activities that concentrate coarser grains. Cross-plots from four statistical parameters and supported by the ANOVA test clearly distinguish the particle variations between these dunes. The log-probability analysis suggest that the main transport mechanism in inland and coastal dunes is dominated by the saltation population, comprising up to 80 percent of the distribution. However, the coastal dunes suspension population is mostly belonging to coarser grained material, whereas the inland dunes population is finer. In comparison with particle size characteristics of dunes in the region, the current study shows a close relationship to mean particle size in Iraq, but is relatively finer compared to the Kuwait dunes. This similarity and difference in particle size variation is mostly controlled by the proximity to the coast and also the wind energy and variation in the wind direction.

The results showed that under the conditions that the climate in north China trends to warming and drying, especially,under the control of the water and heat conditions, the degree of land use difference was significant in the southern marginal zones of Tengger desert and Mu Us desert. The land use level in the studying area was generally increased in the nearly past 30 years. But the land use level in the southern marginal zones of Mu Us desert was higher than that in the southern marginal zones of Tengger desert, as well as the speed of land use change in the southern marginal zones of Mu Us desert.

    Full Text Available Because of dynamic processes of creative economy development and resistance to the crisis of modern creative industries which occurs mainly in metropolitan areas, the interest in understanding these local processes as a factor of bringing international trade competitiveness and providing convergence among the countries where those metropolises are situated is of great value. The EU, and Central and East Europe (CEE in particular, is not an exception. This paper reveals the most productive creative industries in the EU; fins out the impact of metropolises’ creative activities development on countries’ international specialization. Perspective products’ and geographic patterns relating creative products’ international specialization for CEE countries, especially for those which have recently signed association agreements with the EU (Moldova, Ukraine, and Georgia as an important East Neighbour for the EU are grounded. Using inter- and intra-trading estimations, the positioning of CEE countries in the EU 28(+3 international specialization pattern is indicated. The product specialization of metropolises in CEE countries which may (or may not contribute to further internationalization of creative industries in these countries has been revealed in the article.

    Full Text Available The evolution of the Western world has drawn on theoretical structures of classical and neoclassical liberalism for its explanatory support and sources of inspiration for centuries. Against this ideological background, institutionalists aim at showing that growth is a process of transformation, a double change: an economic and an institutional one. In this analysis, our purpose is to highlight the importance of informal institutional arrangements and their quality in explaining the disparities of revenues and developments between countries. In our approach, we will consider several indicators meant to highlight various aspects of research. The approach proposed is a transversal-comparative one and static methods pertain to uni- and multivariate analysis. The results obtained suggest the existence of major differences within the Central and East European area as far as informal institutions are concerned; moreover, the analysis conducted confirms the existence of a significant relation between the level of development and the structure of informal arrangements such as: trust level, bribe culture and corruption control.

    Full Text Available This thesis treats extremely present aspects regarding the evolutions of the emerging economies within the new member states of the European Union insisting on the analysis of the convergence process from a real perspective. Beside the achievement of a monetary union, one of the fundamental objectives of the European Union is represented by the reducing of the disparities regarding the level of development among the member states. One of the ways of appreciating the reduction of the disparities between the economies involve a reduction of the gap as far as the GDP level/inhabitant is concerned or in other words, a real convergence. A series of statistic data are analysed in order to point out the extent to which the central ad East-European states have managed to reduce the gap in report to the developed member states of the EMU, using indicators for the appreciation of the real convergence: the GDP per inhabitant, the monthly average salary, the poverty rate, the contribution of the main sectors of the economy in the formation of the GDP and the unemployment rate. From the analysis of the statistic data one can observe that the highest degree of real convergence is held by Slovenia, which distanced a lot from the other EEC states, followed by the Czech Republic. Regarding from the point of view of the evolution of the EEC countries during the entire analysed period, based on the dynamics of the indicators and of the speed of catching up the gaps we can also notice the performance of the Baltic countries. Unfortunately, Romania and Bulgaria are way behind the other EEC countries.

    MT measurement of transects was made in the central part of North-Eastern Japan Arc to clarify tectonics of subduction zones. 1-D, 2-D and 3-D resistivity structures are observed in surface layers, and zones shallower and deeper than a Conrad surface, respectively. A main structure direction is S-N or NNE-SSW. Ishinomaki-Chokai tectonic line and low- resistivity zones due to Quaternary volcanos (Naruko, Onikobe) exist in a backbone range region. Resistivity is 100{Omega}{center_dot}m or less by Bostick Inversion except Mesozoic and Palaeozoic layers in the southern Kitakami mountainous region, resulting in a good agreement with previous results in a north transect. Resistivity is several {Omega}{center_dot}m and depth is several km around Shinjo basin and in surface layers of Kitakami River region. The backbone range region shows complex resistivity structures because of volcanic activity and wide-area hot water activity. High-resistivity layers correspond to stable Mesozoic and Palaeozoic land layers. Seismic velocity increases in the low-resistivity zone. Earthquake generally occurs at the boundary between resistivity structures. 68 refs., 9 figs., 2 tabs.

  4. Properly pricing country risk: a model for pricing long-term fundamental risk applied to central and eastern European countries

    2010-09-01

    Full Text Available The private sector has used proxies such as sovereign credit ratings, spreads on sovereign bonds and spreads on sovereign credit default swaps (CDS to gauge country risk, even though these measures are pricing the risk of default of government bonds, which is different from the risks facing private participants in cross-border financing. Under normal market conditions, the CDS spreads are a very useful source of information on country risk. However, the recent crisis has shown that the CDS spreads might lead to some underpricing or overpricing of fundamentals in the case of excessively low or excessively high risk aversion. In this paper we develop an alternative measure of country risk that extracts the volatile, short-term market sentiment component from the sover eign CDS spread in order to improve its reliability in periods of market distress. We show that adverse market sentiment was a key driver of the sharp increase in sovereign CDS spreads of central and eastern European (CEE countries during the most severe phase of the crisis. We also show that our measure of country risk sheds some light on the observed stability of cross-border bank flows to CEE banks during the crisis.

  5. Multistation template matching to characterize frequency-magnitude distributions of induced seismicity in the Central and Eastern US

    2015-12-01

    We analyze the frequency-magnitude distribution (FMD) of recent seismic sequences thought to be induced by wastewater injection and hydraulic fracturing in the Central and Eastern U.S. to investigate their physical origin and improve hazard estimates. Multistation template matching is utilized to increase the number of events analyzed by lowering the magnitude of detection. In cases where local deployments are available, we demonstrate that the FMD obtained through template matching using regional data are comparable to those obtained from traditional detection using the local deployment. Since deployments usually occur after seismicity has already been identified, catalogs constructed with regional data offer the advantage of providing a more complete history of the seismicity. We find two primary groups of FMDs for induced sequences: those that generally follow the Gutenberg-Richter power-law and those that generally do not. All of the induced sequences are typically characterized by swarm-like behavior, but the non-power-law FMDs are also characterized by a clustering of events at low magnitudes and particularly low aftershock productivity for a continental interior. Each of the observations in the non-power law FMD cases is predicted by numerical simulations of a seismogenic zone governed by a viscoelastic damage rheology with low effective viscosity in the fault zone. Such a reduction in effective viscosity is expected if fluid injection increases fluid pressures in the fault zone to the point that the fault zone begins to dilate.

    Full Text Available The current research paper aims to assess the impact of sovereign credit ratings on the issuance of government bonds in Central and Eastern Europe. The personal analysis is performed on a sample of government bonds issued by Turkey, Hungary, Czech Republic, Slovak Republic, Poland, Romania and Russia between 2000-2010. The sample includes issues in several currencies (EUR, USD, GBP, JPY, CHF, CZK, PLN, TRY, RUB, RON, HUF. The research paper consists of two different analyses. The first one assesses the degree in which the variation in the initial yield of government bonds issued in one particular currency can be explained by using explanatory variables such as: inflation, sovereign rating corresponding to the issuing country, and the state of crisis (this analysis is performed for each currency separately. The second analysis assesses the degree in which the variation in the maturity of the government bonds issued by a certain country can be explained by using explanatory variables such as: inflation, sovereign rating on the date of issuance, and the state of crisis.

    Full Text Available Central and Eastern Europe has become a player on the international market of foreign direct investment (FDI with the fall of communism in 1990. Liberalization of markets has brought both advantages and disadvantages to new states in transition. Despite modest values of FDI received, the share of the region in total global FDI is increasing. Any type of investment, foreign or domestic one, is considered crucial as it generates employment and contributes to the economic growth .This paper tries to provide an analysis of the effects of FDI on the labor force of this region, and specifically in Romania and Poland. We analyzed the quantitative effect on the labor force, more precisely the effect on the employment. Foreign subsidiaries hold an important part of the occupied population, although the number of foreign firms is lower than the domestic ones. Despite the destruction of jobs in the early transition in the process of restructuring, foreign subsidiaries, both directly and indirectly create jobs and usually at a higher rate than the domestic companies manage to do. During the recent financial crisis, foreign subsidiaries proved to be more resilient and the cut off jobs was lower than in domestic firms.

    Full Text Available While the European Union keeps taking pride in putting forward the existence of a European Social Model, no study or project was carried out in order to foresee the enlargement effects on this model and mainly how the latter could be successfully implemented by the new Member States, having regard to their own characteristics. It is no coincidence that the references to the European Social Model multiplied during the period when the EU was facing its own enlargement. More and more questions were raised concerning the new Member States convergence capacity, as regards Central and Eastern Europe countries in particular, with all the European Union social rules. The trends in the new Member States, as well as their convictions or their lack of conviction, concerning the European Social Model, have major implications on the tomorrow’s social Europe. In which direction is it heading in an enlarged 25 or 27 nations European Union? This study is aimed at answering at this question having regard, in particular, to the economical and social characteristics of the new Member States and to the possible sources that might give rise to blockings in the social field.

  9. Earthquake catalogs for the 2017 Central and Eastern U.S. short-term seismic hazard model

    The U. S. Geological Survey (USGS) makes long-term seismic hazard forecasts that are used in building codes. The hazard models usually consider only natural seismicity; non-tectonic (man-made) earthquakes are excluded because they are transitory or too small. In the past decade, however, thousands of earthquakes related to underground fluid injection have occurred in the central and eastern U.S. (CEUS), and some have caused damage.  In response, the USGS is now also making short-term forecasts that account for the hazard from these induced earthquakes. Seismicity statistics are analyzed to develop recurrence models, accounting for catalog completeness. In the USGS hazard modeling methodology, earthquakes are counted on a map grid, recurrence models are applied to estimate the rates of future earthquakes in each grid cell, and these rates are combined with maximum-magnitude models and ground-motion models to compute the hazard The USGS published a forecast for the years 2016 and 2017.Here, we document the development of the seismicity catalogs for the 2017 CEUS short-term hazard model.  A uniform earthquake catalog is assembled by combining and winnowing pre-existing source catalogs. The initial, final, and supporting earthquake catalogs are made available here.

  10. An Empirical Analysis Of Stock Returns And Volatility: The Case Of Stock Markets From Central And Eastern Europe

    2015-04-01

    Full Text Available The main goal of this paper is to investigate the behaviour of stock returns in the case of stock markets from Central and Eastern Europe (CEE, focusing on the relationship between returns and conditional volatility. Since there is relatively little empirical research on the volatility of stock returns in underdeveloped stock markets, with even fewer studies on markets in the transitional economies of the CEE region, this paper is designed to shed some light on the econometric modelling of the conditional mean and volatility of stock returns from this region. The results presented in this paper provide confirmatory evidence that ARIMA and GARCH processes provide parsimonious approximations of mean and volatility dynamics in the case of the selected stock markets. There is overwhelming evidence corroborating the existence of a leverage effect, meaning that negative shocks increase volatility more than positive shocks do. Since financial decisions are generally based upon the trade-off between risk and return, the results presented in this paper will provide valuable information in decision making for those who are planning to invest in stock markets from the CEE region.

    Two generations of monazite were identified in one mica schist sample from the central zone of the eastern Kunlun Orogen at the northern margin of the Qinghai-Tibet Plateau.The first generation was found in the cores of garnet porphyroblasts with relatively high Y2O3 contents (averaging 1.012±0.088 wt%).The second generation occurs either as inclusions in the rims of garnet porphyroblasts, matrix kyanite, plagioclase and quartz, or as separate crystals associated with matrix biotite and muscovite mostly having a relatively low Y2O3 content (averaging 0.479±0.100 wt%).Electron microprobe (EMP) Th-U-Pbtotal chemical dating for two grains of the first generation monazite yields average ages of 455 ± 18 Ma and 420 ± 20 Ma, respectively; six grains of the second generation gave an average age of 246.1 ± 3.8 Ma.These ages suggest that the core and rim of the garnet porphyroblasts and their associated assemblages record two events of significant tectonometamorphism.The formation of the Ordovician monazite is related to the tectonometamorphic event responsible for continuous amalgamation of the Gondwanaland in the Late Pan-African period or for consumption of the Proto-Tethys, whereas the development of the Triassic monazite is related to the tectonometamorphic event for consumption of the Paleo-Tethys.

    2000-11-01

    A succession of quartz-rich fluvial sandstones and siltstones derived from a mainly rhyolitic source and minor metamorphic rocks, located to the west, represent the first Upper Paleocene-Early Eocene deposits described in Chilean eastern central Patagonian Cordillera (46°45'S). This unit, exposed 25 km south of Chile Chico, south of lago General Carrera, is here defined as the Ligorio Márquez Formation. It overlies with an angular unconformity Lower Cretaceous shallow marine sedimentary rocks (Cerro Colorado Formation) and subaerial tuffs that have yielded K-Ar dates of 128, 125 and 123 Ma (Flamencos Tuffs, of the Divisadero Group). The Ligorio Márquez Formation includes flora indicative of a tropical/subtropical climate, and its deposition took place during the initial part of the Late Paleocene-Early Eocene Cenozoic optimum. The underlying Lower Cretaceous units exhibit folding and faulting, implying a pre-Paleocene-Lower Eocene contractional tectonism. Overlying Oligocene-Miocene marine and continental facies in the same area exhibit thrusts and normal faults indicative of post-Lower Miocene contractional tectonism.

  13. Estimation of intrinsic aquifer vulnerability with index-overlay and statistical methods: the case of eastern Kopaida, central Greece

    2016-03-01

    The intrinsic vulnerability of a karstic aquifer system in central Greece was jointly assessed with the use of a statistical approach and PI method, as a function of topography, protective cover effectiveness and the degree to which this cover is bypassed due to flow conditions. The input data for the index-overlay PI method were derived from field works and 71 boreholes of the area; the information was obtained, subsequently its critical factors were compiled which included lithology, fissuring and karstification of bedrock, soil characteristics, hydrology, hydrogeology, topography and vegetation. The aforementioned parameters were processed jointly with the aid of a GIS and yielded the final estimation of intrinsic aquifer vulnerability to contamination. Results were compared with an equivalent spatially distributed probability map obtained through a stochastic approach. The calibration and test phase of the latter relied on morphometric conditions derived by terrain analyses of a digital elevation model as well as on geology and land use from thematic maps. This procedure allowed taking into account the topographic influences with respect to a deep system such as the local karstic aquifer of eastern Kopaida basin. Finally, results were validated with ground truth nitrate values obtained from 41 groundwater samples, highlighted the spatial delineation of susceptible areas to contamination in both cases and provided a robust tool for regional planning actions and water resources management schemes.

  14. Welfare State Retrenchment in Central and Eastern Europe: The Case of Pension Reforms in Poland and Slovenia

    Igor Guardiancich

    2004-03-01

    Full Text Available This paper endeavours to shed some light on the mechanisms that led to the divergence of welfare state arrangements across Central and Eastern Europe (CEE. In particular, pension system reforms displayed a great deal of variance, which surprised both institutionalists and convergence theorists. The Polish and Slovenian cases are thus presented and compared in a political economy perspective. Theories of retrenchment, recent studies on the dynamics of CEE pension reforms and consultations with some of the relevant actors, were employed in order to account for the divergence of reform outcomes in the two countries. The study focused on three main explanations: partisan competition, the interaction between relevant external (World Bank and internal actors (Minister of Labour and Minister of Finance and the trade-off. between power concentration and accountability concentration. The latter yielded the best explanation. While Polish reformers managed to internalise most veto actors’ reservations, Slovenian politicians excluded from consultation the country’s main trade union. Its opposition determined the rejection of radical reforms recommended by the World Bank.

    Full Text Available The study was carried out during 2011 – 2012 at different water basins (rivers and micro dams situated in Central and Eastern Bulgaria. Transects with 600 m length were walked along the banks in otter signs search. The search was stopped when the first otter signs were registered. As a whole we found domination of the very good or excellent bank tree cover. A total of 61% of transects were with tree cover between 50% and 100%. Almost equal were the stretches without or with little tree vegetation. At all transects surveyed the spraints dominated with 61%. All other otter signs were with low percentage. The otter tracks (foot prints were on second place with 20% of occurrence, followed by the food remains with 7%. At 12% of transects we did not find any otter signs. As a whole the otter was registered in 88% of transects, a sign for a good population. Highest preference we registered for walking or feeding of the otter at the open banks with no or with weak tree cover.

    We have investigated gravity anomalies around the Niigata plain, which is a sedimentary basin in central Japan bounded by mountains, to examine the continuity of subsurface fault structures of a large fault zone—the eastern boundary fault zone of the Niigata plain (EBFZNP). The features of the Bouguer anomaly and its first horizontal and vertical derivatives clearly illustrate the EBFZNP. The steep first horizontal derivative and the zero isoline of the vertical derivative are clearly recognized along the entire EBFZNP over an area that shows no surface topographic features of an active fault. Two-dimensional density structure analyses also confirm a relationship between the two first derivatives and the subsurface fault structure. Therefore, we conclude that the length of the EBFZNP as an active fault extends to 56 km, which is longer than previously estimated. This length leads to an estimation of a moment magnitude of 7.4 of an expected earthquake from the EBFZNP.[Figure not available: see fulltext.

Biodiversitas 12: 235-240. Termites ecological behaviour is much affected by land use change and disturbance level. Their variation in diversity can be used as bioindicator of environmental quality. However, termite community response to land use changes and habitat disturbance in highland ecosystems remains poorly understood. This study was conducted to investigate the response of termite community to land use intensification and to explore their role as environmental bioindicator in Mount Slamet. A standard survey protocol was used to collect termites in five land use typesof various disturbance levels,i.e. protected forest, recreation forest, production forest,agroforestry, and urban area. It was found two termite families i.e. Rhinotermitidae and Termitidae with seven species, i.e Schedorhinotermes javanicus, Procapritermes sp, Pericapritermes semarangi, Macrotermes gilvus, Microtermes insperatus, Nasutitermes javanicus, and N. matanganensis. Termite species’ richness and evenness, Shannon-Wiener index, relative abundance, and biomass of termite were declined along with the land use types and disturbance level from protected forest to urban area. Habitat disturbance was the main declining factor of termite diversity. Termite composition changed along with the land use disturbance level. Soil feeding termites were sensitive to the disturbance – they were not found in urban area. Hence, their presence or absence can be used as environmental bioindicator to detect habitat disturbance.

  18. Insights Into Central And Eastern European Countries Competitiveness: On The Exposure Of Capital Markets To Exchange Rate Risk

    Full Text Available Unexpected fluctuations in exchange rates represent a matter of concern for all businesses nowadays as the volatility in exchange rates impacts businesses’ cash flows, revenues and expenses, and eventually is reflected in the company’s risk-return profile. Companies’ exposures to exchange rate risk have considerably increased in the past decades, given the boost in international operations and the continuous diversification of businesses’ activities at the global level. Despite the attention that businesses display to nominal exchange rates changes, it is the real exchange rate that should be of more concern to corporate managers, since they induce changes at the level of the competitiveness of the business. Our paper comparatively analyzes the exposure to changes in the nominal and real exchanges rates of the local currencies that companies from a number of four Central and Eastern European countries (Romania, Hungary, Czech Republic and Poland and investigates the nature of the relationship between stock market performance and exchange rates in the four countries under consideration. We find limited evidence for contemporaneous and asymmetric exposure to nominal and real exchange rate risk in all four countries, but consistent evidence for three to four months lagged exposure.

    Strong winds and storm surges from Typhoon Haiyan caused damage of US$12-15billion and >10,000 human casualties in central Philippines in November 2013. To validate a proposed government US$22million mangrove replanting program, mangrove damage and short-term recovery were surveyed in seven natural and planted mangrove sites in Eastern Samar province at 2.5month and 4.5month post-Haiyan. The preliminary assessment showed that natural mangroves (except for those directly hit by the storm) were recovering by means of tree sprouts and surviving seedlings and saplings compared to the devastated plantation. Likewise, tree mortality was higher in the plantation and natural forests hit by the storm surge, compared to more undamaged and partially damaged trees in natural mangroves. Hence the main recommendations to government are (1) to protect recovering mangroves by not releasing rehabilitation funds (that will inadvertently pay for clearing of live trees and for removal of seedlings), (2) to only plant in totally damaged sites (e.g., plantations), and (3) to only plant naturally dominant species, e.g., Sonneratia alba and Avicennia marina (instead of the popular Rhizophora apiculata, R. mucronata and R. stylosa).

    Full Text Available The aim of the study was to determine the prevalence of canine dirofilariosis in four provinces of central-eastern Poland and to describe pathological changes occurring during the course of this parasitosis. A total of 188 dogs aged from one and a half up to 16 years were examined for dirofilariosis. Blood samples were analysed for the presence of microfilariae using Knott method, as well as the method of Kingston and Morton. Pathomorphological examination of two dogs was also performed. Histological sections were stained with H&E, AB-PAS, van Gieson, and von Kossa methods. Microfilariae of Dirofilaria repens were found in blood samples of dogs that originated from the Mazowieckie, Lubelskie, and Podlaskie provinces. The mean prevalence of that species was 12.7%. Autopsy revealed the adult nematodes in the subcutaneous connective tissue. Microscopic examinations indicated the presence of microfilariae in the liver, kidneys, lungs, heart muscle, and intestines. Necrotic foci, thrombosis, and infiltrations of different intensity with eosinophils in internal organs were also observed. Significant lesions in different internal organs together with the presence of numerous microfilariae suggest their important role in the disease process.

    Full Text Available Abstract Background Despite the attention the situation of the Roma in Central and Eastern Europe has received in the context of European Union enlargement, research on their access to health services is very limited, in particular with regard to child health services. Methods 50 qualitative in-depth interviews with users, providers and policy-makers concerned with child health services in Bulgaria, conducted in two villages, one town of 70,000 inhabitants, and the capital Sofia. Results Our findings provide important empirical evidence on the range of barriers Roma children face when accessing health services. Among the most important barriers are poverty, administrative and geographical obstacles, low levels of parental education, and lack of ways to accommodate the cultural, linguistic and religious specifics of this population group. Conclusion Our research illustrates the complexity of the problems the Roma face. Access to health care cannot be discussed in isolation from other problems this population group experiences, such as poverty, restricted access to education, and social exclusion.

    Obtaining Pu background data in the environment is essential for contamination source identification and assessment of environmental impact of Pu released from the Fukushima Daiichi nuclear power plant (FDNPP) accident. However, no baseline information on Pu isotopes in Fukushima Prefecture has been reported. Here we analyzed 80 surface soil samples collected from the central-eastern Japan during 1969-1977 for 239+240Pu activity concentration and 240Pu/239Pu atom ratio to establish the baseline before the FDNPP accident. We found that 239+240Pu activity concentrations ranged from 0.004 -1.46 mBq g-1, and 240Pu/239Pu atom ratios varied narrowly from 0.148 to 0.229 with a mean of 0.186 +/- 0.015. We also reconstructed the surface deposition density of 241Pu using the 241Pu/239Pu atom ratio in the Japanese fallout reference material. The obtained results indicated that, for the FDNPP-accident released 241Pu, a similar radiation impact can be estimated as was seen for the global fallout deposited 241Pu in the last decades.

    A reconnaissance survey of the central and eastern basins of Lake Erie (22,240 km/sup 2/) was conducted from September 17 to 27, 1978. The survey provided baseline information on natural gas and oil losses from geologic formations, prior to any potential development of natural gas resources beneath the United States portion of the Lake. Lightweight hydrocarbons indicative of natural gas (methane, ethane, propane, isobutane, and n-butane) are introduced into the waters of Lake Erie by escape from geologic formations and by biological/photochemical processes. The geochemical exploration technique of hydrocarbon sniffing provided enough data to reveal significant distribution patterns, approximate concentrations, and potential sources. Twelve sites with elevated lightweight hydrocarbon concentrations had a composition similar to natural gas. In one area of natural gas input, data analysis suggested a potential negative effect of natural gas on phytoplanktonic metabolism (i.e., ethylene concentration). Samples taken for liquid hydrocarbon analysis (carbon tetrachloride extractable hydrocarbons) correlated best with biologically derived lightweight hydrocarbons.

    Full Text Available Published by Palgrave MacmillanSwitzerland’s State Secretariat for Economic Affairs (SECO has been working in the energy sectors of Eastern Europe and Central Asia since 1992, financing 41 projects to the value of CHF 316 million. In 2009 an independent evaluation was commissioned to assess the effects of these projects in the region and to draw lessons for future project funding. The evaluation found the projects to be highly satisfactory in terms of relevance, satisfactory in terms of effectiveness and sustainability, and — because of external factors relating to governance, transparency and political stability in a country — generally unsatisfactory in terms of efficiency.Lessons drawn from the successful projects will be used to further improve them in the future. With limited financial resources governments are attempting to find a balance between energy security and environmental sustainability. SECO will support this mission by helping to reduce inefficient consumption, to increase the share of renewable energy, to strengthen the sustainability of utility companies and to develop effective energy policies.

This research shows and compares hydrographic, nitrous oxide concentration, and N2O isotopic and isotopomeric data from three stations across the South Pacific Ocean, from the center of the subtropical oligotrophic gyre (~26° S; 114° W to the upwelling zone along the central Chilean coast (~34° S. Althought AOU/N2O and NO3 trends support the idea that most of N2O source (mainly from intermediate water (200–1000 m come from nitrification, N2O isotopomeric composition (intramolecular distribution of 15N isotopes in N2O reveals an abrupt change in the mechanism of nitrous oxide production, always observed through lower SP (site preference of 15N, at a high – stability layer, where particles could act as microsites and N2O would be produced by nitrifier denitrification (reduction of nitrite to nitrous oxide mediated by primary nitrifiers. There, nitrifier denitrification can account for 40% and 50% (center and east border of the gyre, respectively of the nitrous oxide produced in this specific layer. This process could be associated with the deceleration of sinking organic particles in highly stable layers of the water column. In constrast, coastal upwelling system is characterized by oxygen deficient condition and some N deficit in a eutrophic system. Here, nitrous oxide accumulates up to 480% saturation, and isotopic and isotopomer signal show highly complex nitrous oxide production processes, which presumably reflect both the effect of nitrification and denitrification at low oxygen levels on N2O production, but non N2O consumption by denitrification was observed.

The coincidence of this SP signal with high – stability layer, where sinking organic particles can accumulate, suggests that N2O could be produced by nitrifier denitrification inside particles. It is postulated that deceleration of particles in the pycnocline can modify the advection - diffusion balance inside particles, allowing the accumulation of nitrite and O2 depletion suitable for nitrifier denitrication. As lateral advection seems to be relatively insignificant in the gyre, in situ nitrifier denitrification could account for 40–50% of the N2O produced in this layer.

    Lakes and their water quality have been affected by anthropogenic actions for centuries. The most intensive changes have often occurred since the mid-19th century. Industrialization, modern agriculture, forest ditching and artificial lowering of water level are examples of these changes that have usually resulted in the deterioration of lake water quality. Many organisms, such as diatoms, are sensitive to these changes in their environmental conditions. Therefore, a marked species turnover is often seen between the pre and post human impact diatom assemblages. This turnover can be rapidly assessed simultaneously from many lakes by using multivariate methods and top-bottom sampling. Our study area consists of three adjacent lake routes in the grass cultivation and dairy production area of central-eastern Finland, where slash-and-burn cultivation and artificial water level lowering were common practice during the past centuries. The centermost Iisalmi lake route is particularly interesting because of the conspicuously eutrophic lakes in its Kiuruvesi subroute. We used the top-bottom approach to sample pre and post human impact samples from 47 lakes (50 sampling sites) located in the three lake routes. In addition, stratigraphic samples from the long cores of three lakes (one larger central basin and two small upstream lakes) in the Kiuruvesi subroute were studied in more detail. Multivariate methods were used to assess diatom assemblage change within the long cores and between the pre-disturbance and modern samples. The results indicate that most study lakes have undergone a marked shift in their diatom assemblages since the onset of human impact in the area. The lake routes are characterized by differing pre-impact diatom assemblages. However, human influence has reduced their natural variation. Similar diatom species are common in the modern samples of the heavily impacted lakes in all three lake routes. The detailed examination of the diatom assemblage turnover in

    The most common tick species parasitizing animals in Poland are Ixodes ricinus and Dermacentor reticulatus. These tick species differ in their distribution, habitats, seasonal activity and host specificity. Ixodes ricinus is the most prevalent and widely distributed, whereas the range of D. reticulatus is limited to eastern and central parts of the country with several new foci in the middle-west and the west. However, as in many central European countries, the range of D. reticulatus is expanding, and some authors have correlated this expansion with an increasing number of available hosts. The aim of the present study was to determine the tick fauna on domestic and livestock animals in two areas endemic for I. ricinus and D. reticulatus and to compare the risk of infestation with different tick species in open and forest areas. Over a 14 month period, 732 ticks were collected from five host species including domestic animals (dogs and cats), livestock (cows and horses) and wildlife (European bison) in two areas, central and NE Poland, endemic for D. reticulatus. Three tick species were recorded: D. reticulatus (623 individuals; 85.1% of all collected ticks), I. ricinus (106 individuals; 14.5%) and three females of Ixodes hexagonus (0.4%) from a dog. Dermacentor reticulatus was the dominant tick species found on four host species and constituted 86, 81, 97 and 100% of all ticks from dogs, horses, cows and bison, respectively, and was collected from animals throughout the year, including during the winter. The common tick, I. ricinus, was the dominant tick collected from cats (94%). Fully-engorged, ready-for-reproduction females of D. reticulatus were collected from all host species. In May 2012, questing ticks were collected by dragging in forest or open habitats. The density of adult marsh ticks in open areas was around 2 ticks/100 m(2) in the majority of locations, with a maximum of 9.5 ticks/100 m(2). The density of adult I. ricinus was much lower in its typical

    As a part of the CyprusArc project, a seismic wide-angle reflection/refraction profiles were carried out in March 2010. The 300 km and 45 km long north-south trending profiles extended from Cihanbeyli in Central Anatolia to Anamur in eastern Mediterranean, Turkey and in southern Cyprus, respectively. The purpose of the project is to observe the impact of the transition from subduction to continent-continent collision of the African plate with the Anatolian plate. The field experiment comprised two land shots (1125 kg explosives) in Turkey and airguns (98 cubic liters) on the Mediterranean sea, beneath Cyprus. 244 stations were installed on land for data acquisition. 77 three-component sensors and 167 vertical-component sensors were installed along ~300 km distances between Cihanbeyli and Anamur with an average spacing of 1.25 km, on Turkey. 24 three-component sensors and 21 vertical component sensors were deployed along 45 km distances on land at southern Cyprus with an average spacing of 1.25 km. To reveal a good data quality, a visual quality check, frequency analysis and filtering were applied to the seismic data. Two land shots on Turkey (also recorded on Cyprus) and airgun shots on the Mediterranean sea beneath Cyprus, geological and previous seismic investigations provide information to derive a layered velocity models beneath from the Anatolian plateau to eastern Mediterranean, Turkey and for the ophiolite complex on Cyprus. After picking observed seismic phases, finite-differences ray tracing of the wide-angle data leads a 2-D crustal P-wave velocity models. The results show moho depth increases from 38 km to 45 km depth along north-south trending profile on Turkey and crustal thinning between south Turkey and Cyprus from 40 km to 36 km. Obtained models were further refined using forward modeling to generate synthetic seismograms for individual shot gathers. Thus, by varying the velocity structure, the theoretical times and amplitudes of the various

    Annually laminated (varved) sediments with defined event-based age anchor points such as tephra layers enable the establishment of precise chronologies in lacustrine climate archives. This is especially useful to study subtle temporal differences in the consequences of mechanisms and feedbacks during abrupt climatic changes such as the Younger Dryas over larger spatial areas. To decipher the drivers of ecological changes across the Allerød/Younger Dryas transition in central Europe, we analyzed leaf wax biomarkers from Trzechowskie paleolake in northern Poland. Samples were taken in 10 years intervals across the onset of the Younger Dryas, with the Laacher See Tephra (12,880 yrs BP) as anchor point for age-calibration. Further, we applied compound specific hydrogen isotope analysis to infer past hydrological changes, in comparison to results from the well-dated Meerfelder Maar record located up 900 km to the southwest [1]. Between 12,750 and 12,600 yrs BP, ratios of terrestrial n-alkanes show a transition from a tree-dominated lake catchment (Pinus, Betula) to an environment mainly covered by Juniperus and grasses, which is in agreement with palynological data. δD values of n-alkanes indicate a rapid cooling and/or a change of moisture source together with a slight aridification between 12,680 and 12,600 yrs BP. This is synchronous to a rapid and strong aridification inferred for the beginning of the Younger Dryas at Meerfelder Maar (western Germany) [1] but ca. 170 yrs after the inferred onset of cooling at both Meerfelder Maar and the NGRIP ice core at 12,850 yrs BP. This highlights a different temporal succession and impact of hydrological and climatic changes in eastern compared to western Europe which could potentially be related to the stronger influence of the Fennoscandian icesheets and/or the Siberian High on atmospheric circulation patterns in the more continental climate influenced parts of eastern Europe.

    Full Text Available In order to understand the aging and processing of organic aerosols (OA, an intensive field campaign (Campaign of Air Pollution at Typical Coastal Areas IN Eastern China, CAPTAIN was conducted March–April at a receptor site (a Changdao island in central eastern China. Multiple fast aerosol and gas measurement instruments were used during the campaign, including a high resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS that was applied to measure mass concentrations and non-refractory chemical components of submicron particles (PM1nr. The average mass concentration of PM1(PM1nr+black carbon was 47 ± 36 μg m−3 during the campaign and showed distinct variation, depending on back trajectories and their overlap with source regions. Organic aerosol (OA is the largest component of PM1 (30%, followed by nitrate (28%, sulfate (19%, ammonium (15%, black carbon (6%, and chloride (3%. Four OA components were resolved by positive matrix factorization (PMF of the high-resolution spectra, including low-volatility oxygenated organic aerosol (LV-OOA, semi-volatile oxygenated OA (SV-OOA, hydrocarbon-like OA (HOA and a coal combustion OA (CCOA. The mass spectrum of CCOA had high abundance of fragments from polycyclic aromatic hydrocarbons (PAHs (m/z 128, 152, 178, etc.. The average atomic ratio of oxygen to carbon in OA (O / C at Changdao was 0.59, which is comparable to other field studies reported at locations downwind of large pollution sources, indicating the oxidized nature of most OA during the campaign. The evolution of OA elemental composition in the van Krevelen diagram (H / C vs. O / C showed a slope of −0.63; however, the OA influenced by coal combustion exhibits a completely different evolution that appears dominated by physical mixing. The aging of organic aerosols vs. photochemical age was investigated. It was shown that OA / ΔCO, as well as LV-OOA / ΔCO and SV-OOA / ΔCO, positively correlated with photochemical age. LV

    Full Text Available Reserves aim mainly at preventing or mitigating human impacts on natural ecosystems. It is important to assess how well reserves meet this goal. We evaluated whether habitat protection offered by Ñacuñán Biosphere Reserve (Central Monte desert, Argentina results in detectable changes in habitat structure and the species richness and composition of bees and wasps. We conducted pan trap sampling and flower visitor observations in six pairs of protected and unprotected sites. Our results suggest that thirty fi ve years of cattle exclusion in Ñacuñán have had detectable effects on habitat structure. However, these changes in habitat structure translated only into partial and conflicting effects on hymenopteran richness, and did not have detectable effects on hymenopteran composition. Our study should be repeated with a greater sampling effort and throughout multiple years before our results can be applied to guide management decisions.El principal objetivo de las reservas es prevenir o mitigar los impactos humanos sobre los ecosistemas naturales.

    A unique radial tidal sand ridge system (RTSRS) has developed under a complex tidal current field on the eastern China coast between the Yangtze River delta to the south and the abandoned Yellow River (Huanghe) delta to the north. The present study examines the sedimentary evolution of a ridge-channel pair in the central RTSRS. Three cores, with two on the ridges and one in the channel, were drilled to reveal the late Pleistocene-Holocene deposits of the system. Five sedimentary facies were distinguished, i.e. ridge-shallow subtidal facies, ridge-deep subtidal facies, near-surface channel bottom facies, middle tidal flat facies and low tidal flat facies. The ridge-shallow subtidal facies consists of sandy strata with ripple cross bed-dings, horizontal lamina, and massive beddings. Bioturbation seldom occurs. The ridge-deep subtidal facies is primarily characterized by sandy and muddy interlayers with common flaser and lenticular bedding structures. Bioturbation appears abundantly. Massive and graded sediment sequences of storm origin are pre-sent as characterized by rich shell fragments. The near-surface channel bottom facies consists of loose, soft, clayey silt deposits with deformed sedimentary layers. This facies occurs in the deeper part of the active chan-nels. The middle tidal flat and lower tidal flat facies composed of silt-clay couplets prevailed primarily in the tidal flats. Incomplete sedimentary successions show that coastal plain deposits dominate in the study area during 12-13 ka B.P. The sandy ridge and channel facies became dominant during 4 6 ka B.P. when the sea level receded temporarily. Tidal ridge and channel in the study area became active during the last four decades. Sediment reworking due to typhoon and sandy ridge migration plays a key role in shaping the present radial ridge system.

    Full Text Available Background: Family planning confers unique benefits including preventing unintended pregnancies, improving maternal and child health outcomes, and increasing women’s access to education and economic opportunities. However, Uganda has a low contraceptive prevalence rate of only 30%, and progress in improving maternal and child health outcomes is slow. Objective: This assessment explores community health workers’ and facility-based health workers’ qualitative perspectives on the use of contraceptives in the Iganga and Kaliro districts in Eastern Central Uganda. Methods: The baseline assessment used a qualitative approach with a focused sample of community- and facility-based health workers aged 20-60 years. Two focus group discussions with Community Health Workers and four key informant interviews with facility-based health workers were conducted. Thematic content analysis was done manually. Results: The main factors influencing contraceptive use in these communities were preference for large families, perceived inadequate knowledge of family planning and fear of side effects, inadequate spousal and family support, male domination and risk of violence, divorce and polygamy, inadequate human resource capacity and low motivation, and user fees. Conclusion: The study findings suggest that there is low use of contraceptives for family planning in the Kaliro and Iganga districts in Uganda. Recommendations include developing a strong focus in exploring policy options to build the capacities of trained health workers to offer long-term methods in order to increase the availability of family planning options. Family planning interventions should increase the availability of contraceptive methods using gender-sensitive strategies, including community mobilization.

    China is one of the key regions of the world where agricultural civilizations already flourished several millennia ago. However, the role of human activity in vegetation change is not yet fully understood. As a contribution to the PAGES LandCover6k initiative, this study aims to achieve a first attempt at Holocene land-cover reconstructions in the temperate zone of China using the REVEALS model (Sugita, 2007). Pollen productivity estimates (PPEs) are key parameters required for the model and were lacking so far for major taxa characteristic of ancient cultural landscapes in that part of the world. Remains of traditional agricultural structures and practices are still found in the low mountain ranges of the Shandong province located in central-eastern China. The area was chosen for a study of pollen-vegetation relationships and calculation of pollen productivity estimates. Pollen counts and vegetation data from 37 random sites within an area of 200 x 100 km are used for calculation. The vegetation inventory within 100 meters from the pollen sampling site follows the standard methods of Bunting et al. (2013). Vegetation data beyond 100 meters up to 1.5 km from the pollen sampling site is extracted from satellite images. The PPEs are calculated using the three sub-models of the Extended R-value model and compared with existing PPEs from northern China's biomes and temperate Europe. The PPEs' relevance for reconstruction of past human-induced land-cover change in temperate China are evaluated.

    Full Text Available Over the last decade, there has been increasing economic importance of purple passion fruit in Kenya. The primary objective of this study was to assess the input-output transformation process in purple passion fruit production in Central-Eastern and North-Rift Kenya in order to identify avenues for improving and sustaining productivity. Cross-sectional data from 123 multistage sampled farmers was collected using a structured questionnaire, which was subjected to stochastic frontier in STATA 11 for analysis. The results showed that the purple passion fruit production input elasticity was 0.95 which represented decreasing returns to scale (DRS. The results also indicated that passion fruit farm size and manure had a negative and positive significant effect on purple passion fruit yields at 1% significance level, respectively. On the other hand, number of seedlings and hired labour variables had positive and significant effect on the fruit yields at 5% level. The results implied that passion farm size was overused while manure, number of seedlings and hired labour were underused. The gamma parameter (γ was 0.86 which indicates that 86% of the total variation in purple passion fruit output was due to technical inefficiencies. The overall mean technical efficiency (TE was 59% which indicated a cost saving estimate of 32% for the average farmer in attaining the TE of the most technically efficient farmer (86%. The study recommends up-scaling of passion fruit farming information systems so as to provide a basis for optimal use of production resources.

    The eastern fall cohort of the neon flying squid, Ommastrephes bartramii, has been commercially exploited by the Chinese squid jigging fleet in the central North Pacific Ocean since the late 1990s. To understand and identify their optimal habitat, we have developed a habitat suitability index (HSI) model using two potential important environmental variables - sea surface temperature (SST) and sea surface height anomaly (SSHA) - and fishery data from the main fishing ground (165°-180°E) during June and July of 1999-2003. A geometric mean model (GMM), minimum model (MM) and arithmetic weighted model (AWM) with different weights were compared and the best HSI model was selected using Akaike's information criterion (AIC). The performance of the developed HSI model was evaluated using fishery data for 2004. This study suggests that the highest catch per unit effort (CPUE) and fishing effort are closely related to SST and SSHA. The best SST- and SSHA-based suitability index (SI) regression models were SISST-bsed = 0.7SIeffort-SST + 0.3 SICPUE-SST, and SISSHA-based = 0.5SIeffon-SSHA + 0.5SICP,UE-SSHA,respectively, showing that fishing effort is more important than CPUE in the estimation of SI. The bestHSI model was the AWM, defined as HSI=0.3SISST-based+ 0.7SISSHA-based, indicating that SSHA is moreimportant than SST in estimating the HSI of squid. In 2004, monthly HSI values greater than 0.6 coincidedwith the distribution of productive fishing ground and high CPUE in June and July, suggesting that themodels perform well. The proposed model provides an important tool in our efforts to develop forecastingcapacity of squid spatial dynamics.

    Full Text Available In this paper, we examine the attitudes towards gender roles among higher education students in a borderland Central-Eastern European region. We used the database of ‘The Impact of Tertiary Education on Regional Development’ project (N=602, 2010. We intend to determine what kind of attitudes towards gender roles the students identify themselves with, what affects these attitudes (gender, faculty type, social background of students, locality type, religiosity, and finally what kind of educational policy implications could be relevant concerning our findings. We have used cluster analysis and a logistic regression model, and formulated several hypotheses that were controlled by these methods. Our results show that there are a large number of students who belong to the more traditional attitude cluster in this region, but women more frequently identify themselves with modern gender roles than men do. The faculty-type effect has only been partly detected. We have found that with ‘male-dominated’ majors, both women and men identify themselves with more traditional attitudes and that with ‘female-dominated’ majors all students have more modern attitudes. The effect of social background is contradictory. Those whose parents had larger numbers of books had increased modern attitudes, but the factor ‘regular financial problems in the family’ also increased it. Our next result is that students who live in villages are not more traditional than others, because they live in cities during their studies. Our final result is that churchly religious students think more traditionally regarding gender roles than others do, but those who are religious in their own way do not.

  3. Maximum magnitude (Mmax) in the central and eastern United States for the 2014 U.S. Geological Survey Hazard Model

    Wheeler, Russell L.

    2016-01-01

    Probabilistic seismic‐hazard assessment (PSHA) requires an estimate of Mmax, the moment magnitude M of the largest earthquake that could occur within a specified area. Sparse seismicity hinders Mmax estimation in the central and eastern United States (CEUS) and tectonically similar regions worldwide (stable continental regions [SCRs]). A new global catalog of moderate‐to‐large SCR earthquakes is analyzed with minimal assumptions about enigmatic geologic controls on SCR Mmax. An earlier observation that SCR earthquakes of M 7.0 and larger occur in young (250–23 Ma) passive continental margins and associated rifts but not in cratons is not strongly supported by the new catalog. SCR earthquakes of M 7.5 and larger are slightly more numerous and reach slightly higher M in young passive margins and rifts than in cratons. However, overall histograms of M from young margins and rifts and from cratons are statistically indistinguishable. This conclusion is robust under uncertainties inM, the locations of SCR boundaries, and which of two available global SCR catalogs is used. The conclusion stems largely from recent findings that (1) large southeast Asian earthquakes once thought to be SCR were in actively deforming crust and (2) long escarpments in cratonic Australia were formed by prehistoric faulting. The 2014 seismic‐hazard model of the U.S. Geological Survey represents CEUS Mmax as four‐point probability distributions. The distributions have weighted averages of M 7.0 in cratons and M 7.4 in passive margins and rifts. These weighted averages are consistent with Mmax estimates of other SCR PSHAs of the CEUS, southeastern Canada, Australia, and India.

    The North American Amphibian Monitoring Program (NAAMP) was a collaborative citizen science effort between the US Geological Survey (USGS) and 26 Partners (state agencies, universities, and nonprofits) for monitoring calling amphibian populations over much of the eastern and central United States. Initiated in 1997 in response to needs set forth by the Declining Amphibian Populations Task Force in 1994 regarding increased anecdotal observations of global amphibian declines, NAAMP was designed to provide scientifically and statistically defensible, long-term distribution and trends data for calling amphibian populations at the state and regional level in the United States. The USGS discontinued coordination of the program at the conclusion of the 2015 field season. Modeled after the USGS Breeding Bird Survey, NAAMP used a network of random and state-requested non-random roadside routes with listening stops near wetlands to collect frog and toad occupancy and environmental data in predominantly unprotected lands. Data collection and verification under a unified protocol began in 2001 and continued through 2015 with the addition of observer assessment scores in 2006. The USGS utilized verified 2001-2015 data from random routes to produce occupancy trend reports for anuran species of the Northeast, Southeast, and Midwest regions and states of the United States. This dataset includes all raw, verified NAAMP data from 1997 through 2015 and also raw, verified data from Partner States that precede the program (1994-1996). Data preceding 2001 followed variations of the unified protocol. Please refer to metadata for additional information regarding protocol and a list of the represented states and see the Species.csv file for the list of 58 represented species.

  5. Full waveform inversion of seismic reflection data from the Forsmark planned repository for spent nuclear fuel, eastern central Sweden

    2014-02-01

    The Swedish Nuclear Fuel and Waste Management Company (SKB) has been carrying out extensive studies at the planned repository for spent nuclear fuel at the Forsmark site in the eastern part of central Sweden since 2002. Identification of subhorizontal to gently dipping seismic reflections is especially important since these may represent transport routes for radionuclides. Studies have shown that such reflections can be generated by water filled fracture zones that have a lower velocity than the surrounding bedrock. Lithological changes, that is, mafic sills, may also be responsible for reflections in some cases. At the Forsmark site, it is difficult to distinguish fracture zones from mafic sills in the standard reflection seismic processed sections. However, since mafic sills usually have a positive velocity contrast with the background velocity field compared to fractures zones that have a negative one, the two possibilities could be differentiated if we could reconstruct the underground velocity field. Seismic full waveform inversion has the potential to perform this reconstruction, allowing us to discriminate between fractures zones and mafic sills. In this study, we apply a 2-D waveform inversion code on crooked line data sets acquired at the Forsmark site. This implies we are dealing with a 3-D geometry. We handle this problem by applying 3-D to 2-D coordinate projections. First, we perform a synthetic benchmark test with a similar geometry to that of the projected real data. We test both amplitude and phase inversion and phase only inversion on the synthetic data. The results show that the phase only inversion has fewer artefacts and is more stable. After successful application on the synthetic data, we apply the phase only waveform inversion on the real data. The resulting velocity fields show more details compared with the starting model based on first arrival traveltime tomography.

    Health disparities between the western, central and eastern regions of rural China, and the impact of national health improvement policies and programming were assessed. A total of 400 counties were randomly sampled. ANOVA and Logistic regression modeling were employed to estimate differences in health outcomes and determinants. Significant differences were found between the western, central and eastern rural regions in community infrastructure and health outcomes. From 2000 to 2010, health indicators in rural China were improved significantly, and the infant mortality rate (IMR), maternal mortality rate (MMR) and under 5 mortality rate (U5MR) had fallen by 62.79%, 71.74% and 61.92%, respectively. Central rural China had the greatest decrease in IMR (65.05%); whereas, western rural China had the greatest reduction in MMR (72.99%) but smallest reduction in U5MR (57.36%). Despite these improvements, Logistic regression analysis showed regional differences in key health outcome indicators (odds ratios): IMR (central: 2.13; western: 5.31), U5MR (central: 2.25; western: 5.69), MMR (central: 1.94; western: 3.31), and prevalence of infectious diseases (central: 1.62; western: 3.58). The community infrastructure and health outcomes of the western and central rural regions of China have been improved markedly during the first decade of the 21st century. However, health disparities still exist across the three regions. National efforts to increase per capita income, community empowerment and mobilization, community infrastructure, capacity of rural health facilities, and health literacy would be effective policy options to attain health equity.

    1 A classic biogeographic pattern is the alignment of diploid, tetraploid and hexaploid races of creosote bush (Larrea tridentata) across the Chihuahuan, Sonoran and Mohave Deserts of western North America. We used statistically robust differences in guard cell size of modern plants and fossil leaves from packrat middens to map current and past distributions of these ploidy races since the Last Glacial Maximum (LGM). 2 Glacial/early Holocene (26-10 14C kyr BP or thousands of radiocarbon years before present) populations included diploids along the lower Rio Grande of west Texas, 650 km removed from sympatric diploids and tetraploids in the lower Colorado River Basin of south-eastern California/south-western Arizona. Diploids migrated slowly from lower Rio Grande refugia with expansion into the northern Chihuahuan Desert sites forestalled until after ???4.0 14C kyr BP. Tetraploids expanded from the lower Colorado River Basin into the northern limits of the Sonoran Desert in central Arizona by 6.4 14C kyr BP. Hexaploids appeared by 8.5 14C kyr BP in the lower Colorado River Basin, reaching their northernmost limits (???37??N) in the Mohave Desert between 5.6 and 3.9 14C kyr BP. 3 Modern diploid isolates may have resulted from both vicariant and dispersal events. In central Baja California and the lower Colorado River Basin, modern diploids probably originated from relict populations near glacial refugia. Founder events in the middle and late Holocene established diploid outposts on isolated limestone outcrops in areas of central and southern Arizona dominated by tetraploid populations. 4 Geographic alignment of the three ploidy races along the modern gradient of increasingly drier and hotter summers is clearly a postglacial phenomenon, but evolution of both higher ploidy races must have happened before the Holocene. The exact timing and mechanism of polyploidy evolution in creosote bush remains a matter of conjecture. ?? 2001 Blackwell Science Ltd.

  11. Along-Strike Variations in the Timing of Melt Crystallization and Metamorphism Across Central and Eastern Bhutan: New Insights from LASS Monazite Geochronology and Trace-Element Abundances

    Continent-continent collisional systems represent the largest orogens on Earth and provide locations to study processes that drive the transition from contraction and crustal thickening to extension and collapse. The Greater Himalayan Zone (GHZ) exposed along strike of the Himalayan orogen contains exhumed mid-crustal metasedimentary rocks. To better understand the history of burial, crustal flow, and partial melting during the early stages of Himalayan tectonics in the Eocene to ~40 Myr into its orogenic evolution, monazite was analyzed from five migmatitic gneisses and five host gneisses exposed across two transects within central and eastern Bhutan. Monazite was analyzed in situ by the split-stream laser-ablation (LASS) ICPMS technique, which allows simultaneous collection of U-Th-Pb isotopes and trace-element abundances. The migmatites from the eastern Bhutan transect yield monazite dates that record melt crystallization as young as ca. 15-13 Ma. The host gneisses yield similar to younger (down to ca. 11 Ma) dates, documenting coeval to continued metamorphism of the GHZ. In comparison, melt crystallization in the central Bhutan rocks ended by ca. 18 Ma, and metamorphic monazite from a metapelite record metamorphism until ca. 14 Ma. In the migmatite and host-rock samples from both transects, the trace-element data show an inverse correlation between date and the HREE concentration. This trend likely documents the breakdown of garnet, which probably coincides with the first stages of GHZ exhumation. Thus, the LASS data showed that garnet breakdown and GHZ exhumation occurred from ca. 18 to 14 Ma in eastern Bhutan and ca. 20 to 17 Ma in central Bhutan. The new monazite data suggest different histories for the melt crystallization, metamorphism, and exhumation of the GHZ rocks between central and eastern Bhutan, even though the present day rocks from the two transects are only exposed ~60 km apart. Moreover, in comparison to other parts of the eastern Himalaya, the

    According to the "Netlike Plastic-Flow (NPF)" continental dynamics model, the transition of the deformation regime from brittle in shallow layers to ductile in deep layers in the lithosphere, and the controlling effect of NPF in the lower lithosphere result in intraplate multilayer tectonic deformation. NPF is a viscous (plastic) flow accompanied by shear strain localization, forming a plastic-flow network in the lower lithosphere. The strain rates in the seismogenic layer can be estimated using the "earthquake-recurrence-interval" method, in which the strain rate is calculated in terms of the recurrence interval of two sequential carthquakes and the seismic probability of the second earthquake. The strains in the lower lithosphere are estimated using the "conjugate-angle" method, which takes the relationship between the conjugate angles and the compressive strains of the network, and calculates the characteristic strain rates in this layer from the strains and the durations of deformation inferred. The contour map of characteristic maximum principal compressive strain rates in the lower lithosphere in central-eastern Asia given in the paper shows strain rates with magnitudes on the order of 10-15 ~ 10-14/s in this region. The strain rates within the plastic-flow belts,which control seismic activities in the seismogenic layer, are greater than the characteristic strain rates of the network and, in addition, the strain rates and seismic activities in the seismogenic layer are also influenced by other factors, including the directive action of driving boundary along the upper crust, the effects of plastic-flow waves and the existence of the transitional weak layer distributed discontinuously between the upper and lower layers. The comparison between the strain rates in the seismogenic layer and the characteristic strain rates in the lower lithosphere for 11 potential hypocenter areas in the region from the Qinghai-Xizang (Tibet) plateau to the North China plain

    In Central and Eastern Europe following the political transformations of the late 1980s and early 1990s there were dramatic declines in marriage and childbearing, significant increases in nonmarital cohabitation and childbearing, and a movement from reliance on abortion to a reliance on contraception for fertility limitation. Although many explanations have been offered for these trends, we offer new explanations based on ideational influences and the intersection of these ideational influences with structural factors. We focus on the political, economic, social, and cultural histories of the region, with particular emphasis on how countries in the region have interacted with and been influenced by Western European and North American countries. Our explanations emphasize the role of developmental models in guiding change in the region, suggesting that developmental idealism influenced family and demographic changes following the political transformations. Developmental idealism provides beliefs that modern family systems help to produce modern political and economic accomplishments and helps to establish the importance of freedom and equality as human rights in both the public and private spheres. The disintegration of the governments and the fall of the iron curtain in the late 1980s and early 1990s brought new understanding about social, economic, and family circumstances in the West, increasing consumption aspirations and expectations which clashed with both old economic realities and the dramatic declines in economic circumstances. In addition, the dissolution of the former governments removed or weakened systems supporting the bearing and rearing of children, and, the legitimacy of the former governments and their programs was largely destroyed, removing government support for old norms and patterns of behavior. In addition, the attacks of previous decades on the religious institutions in the region had in many places left these institutions weak. During this

    Uncertainties posed by climate change and rapidly rising global water demand suggest that existing conflicts over water resources are likely to be exacerbated and new conflicts will appear where little or no conflict occurs today. Successfully planning for and preventing conflicts first requires a sound scientific understanding of the timing, location, and magnitude of water resource shortfalls, identification of the most appropriate climate adaptation options based on multiple criteria, and development of broad, multi-level consensus within the affected community. We recently applied this approach in a World Bank-funded adaptation assessment for the agricultural sectors of four countries in Eastern Europe and Central Asia-Albania, Macedonia, Moldova, and Uzbekistan. For each major basin, we first used a hydrological model to project changes in water availability through 2050 under country-specific high, medium, and low climate impact scenarios. Next, under the three climate scenarios, we projected changes in agricultural water demand using a crop model (i.e., AquaCrop and DSSAT), and changes in water demand in other sectors based on population projections and sectoral forecasts of changes in per capita use. We incorporated these water availability and demand projections-along with other characteristics of the water system such as water supply priorities, environmental and transboundary flow requirements, irrigation efficiency, and reservoir locations and volumes-into a monthly integrated water resource planning tool (the Water Evaluation And Planning tool, or WEAP) to generate projected unmet water demand under each climate scenario and to each sector through 2050. The findings suggest that the agricultural sector in each country (except the relatively water-rich Albania) would experience significant unmet water demands, up to 52 percent in the Syr Darya and Amu Darya River basins of Uzbekistan. Potential adaptation responses to address unmet water demands-such as

    Deep-large faults in the central continental margin of eastern China are well developed. Based on the regularity of spatial and temporal distribution of the faults,four fault systems were divided: the Yanshan orogenic belt fault system, the Qinling-Dabie-Sulu orogenic belt fault system, the Tanlu fault system and the East China Sea shelfbasin-Okinawa trough fault system. The four fault systems exhibit different migration behaviors. The Yanshan orogenic belt fault system deflected from an EW to a NE direction,then to a NNE direction during the Indo-Chinese epoch-Yanshanian epoch. The thrust-nappe strength of the Qinling-Dabie orogenic belt fault system showed the tendency that the strength was greater in the south and east, but weaker in the north and west. This fault system faulted in the east and folded in the west from the Indo-Chinese epoch to the early Yanshanian epoch. At the same time, the faults also had a diachronous migration from east to west from the Indo-Chinese epoch to the early Yanshanian epoch. On the con-trary, the thrust-nappe strength was greater in the north and west, weaker in the south and east during the late Yanshanian epoch-early Himalayan epoch. The Tanlu fault system caused the basin to migrate from west to east and south to north. The migration regularity of the East China Sea shelf basin-Okinawa trough fault system shows that the for mation age became younger in the west. The four fault systems and their migration regularities were respectively the results of four different geodynamic backgrounds. The Yanshan orogenicbelt fault system derived from the intracontinental orogeny.The Qinling-Dabie-Sulu orogenic belt fault system derived from the collision of plates and intracontinental subduction.The Tanlu fault system derived from the strike-slip movement and the East China Sea shelf basin-Okinawa trough fault system derived from plate subduction and retreat of the subduction belt.

    Since 2001, the number of M>3 earthquakes increased significantly in Central and Eastern United States (CEUS), likely due to waste-water injection, also known as "induced earthquakes" [Ellsworth, 2013]. Because induced earthquakes are driven by short-term external forcing and hence may behave like earthquake swarms, which are not well characterized by branching point-process models, such as the Epidemic Type Aftershock Sequence (ETAS) model [Ogata, 1988]. In this study we focus on the 02/15/2014 M4.1 South Carolina and the 06/16/2014 M4.3 Oklahoma earthquakes, which likely represent intraplate tectonic and induced events, respectively. For the South Carolina event, only one M3.0 aftershock is identified by the ANSS catalog, which may be caused by a lack of low-magnitude events in this catalog. We apply a recently developed matched filter technique to detect earthquakes from 02/08/2014 to 02/22/2014 around the epicentral region. 15 seismic stations (both permanent and temporary USArray networks) within 100 km of the mainshock are used for detection. The mainshock and aftershock are used as templates for the initial detection. Newly detected events are employed as new templates, and the same detection procedure repeats until no new event can be added. Overall we have identified more than 10 events, including one foreshock occurred ~11 min before the M4.1 mainshock. However, the numbers of aftershocks are still much less than predicted with the modified Bath's law. For the Oklahoma event, we use 1270 events from the ANSS catalog and 182 events from a relocated catalog as templates to scan through continuous recordings 3 days before to 7 days after the mainshock. 12 seismic stations within the vicinity of the mainshock are included in the study. After obtaining more complete catalogs for both sequences, we plan to compare the statistical parameters (e.g., b, a, K, and p values) between the two sequences, as well as their spatial-temporal migration pattern, which may

    Full Text Available This paper empirically investigates the impact of the Global financial crisis on the efficiency of four Central and Eastern European emerging unit-linked insurance markets, applying the automatic variance ratio (AVR test of Kim (2009 and variance ratio tests using ranks and signs by Wright (2000 for entire, pre-crisis and crisis periods. This study contributes to the existing literature on efficient market hypothesis with several distinct features: it provides a systematic review of the weak-form market efficiency literature that examines return predictability of the daily ING unit-linked funds prices; also the article aims at monitoring any improvement in the degree of efficiency in time and also examines the relative efficiency of unit-linked insurance markets in pre-crisis and crisis periods. Unit linked insurance are life insurance policies with investment component. In the literature there are few studies investigating the effects of a financial crisis on the potential of predictability and implicitly on the degree of efficiency of financial markets. The occurrence of a market crash or financial crisis is a possible contributing factor of market inefficiency. Most of the studies are focused on the Asian crisis in 1997: Holden et al. (2005 examined the weak-form efficiency of eight emerging Asian stock markets using VR tests before, during and after the Asian crisis; Kim and Shamsuddin (2008 used three different types of multiple VR tests for nine Asian stock markets; the findings reported by Lim et al. (2008 are consistent with those reported by Cheong et al. (2007, in which the highest inefficiency occurs during the crisis period. Todea and Lazar (2010 investigated the effects of the Global crisis on the relative efficiency of ten CEE stock markets, using Generalized Spectral test of Escanciano and Velasco (2006. Wright (2000 proposes the alternative non-parametric variance ratio tests using ranks and signs of return and demonstrates that

    Full Text Available The following study is meant to be an extension of and completion to a former research paper entitled “The Role of Foreign Language Teachers in Developing Students’ Intercultural Communication Skills” concluding that students of the University of Oradea, Romania, generally lack intercultural sensitivity and it falls to a great extent to foreign language teachers to change this state of affairs. When the former study came up with proposals for methods of enhancing students’ cultural awareness (see simulation games on cultural differences like Barnga, BaFá BaFá, Randömia Balloon Factory and others, the present study focuses on an international comparison, though limited to only three academic institutions in three countries, regarding Eastern and Central European students’ intercultural sensitivity. The initial idea was to see to what extent students of the University of Oradea, Romania, studying Economics, Medicine and Law dispose of intercultural skills. For this reason a Likert-type scale questionnaire was applied to more than 200 students of the above mentioned faculties. The survey was extended in the second round in Oradea, Romania, also to the Faculty of Environmental Protection and that of Electrical Engineering and Information Technology, respectively to an international level asking students of the University of Debrecen, Hungary and the University of Maribor, Slovenia, the same questions. Although we are aware of the limitations of present study, – only three institutions included in the research, having in Debrecen and Maribor less respondents than in Oradea and only from some fields of study, Slovenian students not getting a Slovenian version of the questionnaire, which may have influenced their level of understanding issues, responses not always being consistent – its results have still an informative value. They confirm the author’s initial hypothesis that in spite of the extended international relations and

    The 12 May 2008 Wenchuan earthquake (M 7.9) occurred along the western edge of the eastern China SCR and was well recorded by modern strong-motion instruments: 93 strong-motion stations within 1.4 to 300 km rupture distance recorded the main event. Preliminary comparisons show some similarities between ground-motion attenuation in the Wenchuan region and the central and eastern United States, suggesting that ground motions from the Wenchuan earthquake could be used as a database providing constraints for developing GMPEs for large earthquakes in the central and eastern United States.

    Growing pressure to develop public lands for renewable energy production places several protected species at increased risk of habitat loss. One example is the Mojave desert tortoise (Gopherus agassizii), a species often at the center of conflicts over public land development. For this species and others on public lands, a better understanding of their habitat needs can help minimize negative impacts and facilitate protection or restoration of habitat. We used radio-telemetry to track 46 neonate and juvenile tortoises in the Eastern Mojave Desert, California, USA, to quantify habitat at tortoise locations and paired random points to assess habitat selection. Tortoise locations near burrows were more likely to be under canopy cover and had greater coverage of perennial plants (especially creosote [Larrea tridentata]), more coverage by washes, a greater number of small-mammal burrows, and fewer white bursage (Ambrosia dumosa) than random points. Active tortoise locations away from burrows were closer to washes and perennial plants than were random points. Our results can help planners locate juvenile tortoises and avoid impacts to habitat critical for this life stage. Additionally, our results provide targets for habitat protection and restoration and suggest that diverse and abundant small-mammal populations and the availability of creosote bush are vital for juvenile desert tortoises in the Eastern Mojave Desert.

    The central and eastern Mediterranean is a receptor area for persistent organic pollutants (POPs) emitted in western, central and eastern Europe, particularly during summer. Atmospheric concentrations of PCBs, DDXs, PBDEs, penta- and hexachlorobenzene were measured during a ship-borne survey in the summer of 2010. The concentration of PCBs (sum of 7 congeners) was 3.61 (2.08-7.72) pg m-3, of which 6.7% was associated with the particulate phase. The mean concentration of DDT isomers and their metabolites, DDE and DDD, was 2.60 (0.46-7.60) pg m-3 (particulate mass fraction θ = 0.097), of penta- and hexachlorobenzene 0.22 (PBDEs (sum of 8 congeners) 7.31 (2.80-19.89) pg m-3. The air masses studied had been transported mostly across central Europe, some crossing western Europe. The observed changes of PCB congener patterns along transport routes are in agreement with the perception that the reaction with the OH radical is dominating PCB atmospheric lifetime, and indicate an overestimation of the second order gas-phase reaction rate coefficient of PCB153 with OH by structure-activity relationship.

    We examined how acceptance of euthanasia among the general public has changed between 1981 and 2008 in western and central and eastern European (CEE) countries using data of the European Values Surveys. Data were collected in 1981, 1990, 1999 and 2008 for 13 western European countries and in 1990, 1999 and 2008 for 10 CEE countries. Euthanasia acceptance increased each decade up until 2008 in 11 of 13 western European countries; in CEE countries, it decreased or did not increase between 1999-2008 in 8 of 10 countries. A number of explanations for and implications of this apparent east-west polarization are suggested.

  5. Impacts of decaying eastern and central Pacific El Niños on tropical cyclone activities over the western North Pacific in summer

    We investigate the influences of the decaying eastern Pacific El Niño (EP-El Niño) and central Pacific El Niño (CP-El Niño) on tropical cyclone (TC) activities in the western North Pacific (WNP) during July, August, and September (JAS). During this period, TC geneses and tracks are reduced in the central and eastern WNP. However, TC tracks reaching the Philippines increase, and more TC geneses appear west of 145°E during EP-El Niño. During CP-El Niño, tracks reaching the South China Sea (SCS) and southeast coast of China increase, and positive anomalies of TC genesis are found in the southern part of the central WNP and southern SCS. It is possible that the different variations of the anomalous anticyclone over east of the Philippines in the WNP induced by El Niños are instrumental to the different TC variations in the two types of decaying El Niños during JAS. Compared with EP-El Niño, strengthening and northward expansion of the anomalous anticyclone during CP-El Niño cause a westward shift of the western Pacific subtropical high in summer, which is responsible for more westward TC tracks over the SCS and southeast coast of China. This northward expansion can cause the center of suppressed TC geneses in the central WNP to migrate further north during CP-El Niño. A decreased magnitude of vertical shear dominates the southern part of the central WNP and southern SCS, which enhances TC formation in these regions during CP-El Niño.

The root topological indices of the two desert plants were small, and the root branching patterns were herring-bone-like. The roots of the two desert plants had obvious fractal characteristics, with the fractal di-mension of R. soongorica and N. tangutorum being (1.18±0.04) and (1. 36±0.06) , respective-ly. The root fractal dimension and fractal abundance were significantly positively correlated with the root average link length. The root average link lengths of the two plants were long, which enlarged the plants' effective nutrition space, and thus, made the plants adapt to the dry and infertile soil environment. The sums of the root cross-sectional areas before and after the root bifurcation of the two desert plants were equal, which verified the principle of Leonardo da Vinci. A total of 17 pa-rameters of root architecture were analyzed

    The world's domestic cats carry patterns of sequence variation in their genome that reflect a history of domestication and breed development. A genetic assessment of 979 domestic cats and their wild progenitors-Felis silvestris silvestris (European wildcat), F. s. lybica (Near Eastern wildcat), F. s. ornata (central Asian wildcat), F. s. cafra (southern African wildcat), and F. s. bieti (Chinese desert cat)-indicated that each wild group represents a distinctive subspecies of Felis silvestris. Further analysis revealed that cats were domesticated in the Near East, probably coincident with agricultural village development in the Fertile Crescent. Domestic cats derive from at least five founders from across this region, whose descendants were transported across the world by human assistance.

    Full Text Available The onset of the independence process in Central and Eastern European (CEE countries during the 1990s was marked by tremendous optimism and a declared wish for stronger fiscal decentralisation and the transfer of powers, responsibilities and resources to the units of local and regional self-government that were supposed to be closest to citizens in resolving their daily problems. However, this has not happened in these countries, at least not according to the basic financial decentralisation indicators, and this is the main thesis of this work. Despite numerous adjustments made in the local self-government organisation in the observed countries, an optimum level of local and regional self-government organisation has still not been achieved. The units of local and regional self-government are still heavily dependent on, or rather restricted by, the strong central governments, which reduces their autonomy and their influence on the local social and economic development.

  11. Sizes of the Largest Possible Earthquakes in the Central and Eastern United States - Summary of a Workshop, September 8-9, 2008, Golden, Colorado

    Most probabilistic seismic-hazard assessments require an estimate of Mmax, the magnitude (M) of the largest earthquake that is thought possible within a specified area. In seismically active areas such as some plate boundaries, large earthquakes occur frequently enough that Mmax might have been observed directly during the historical period. In less active regions like most of the Central and Eastern United States and adjacent Canada, large earthquakes are much less frequent and generally Mmax must be estimated indirectly. The indirect-estimation methods are many, their results vary widely, and opinions differ as to which methods are valid. This lack of consensus about Mmax estimation increases the uncertainty of hazard assessments for planned nuclear power reactors and increases design and construction costs. Accordingly, the U.S. Geological Survey and the U.S. Nuclear Regulatory Commission held an open workshop on Mmax estimation in the Central and Eastern United States and adjacent Canada. The workshop was held on Monday and Tuesday, September 8 and 9, 2008, at the U.S. Geological Survey offices in Golden, Colorado. Thirty-five people attended. The workshop goals were to reach consensus on one or more of: (1) the relative merits of the various methods of Mmax estimation, (2) which methods are invalid, (3) which methods are promising but not yet ready for use, and (4) what research is needed to reach consensus on the values and relative importance of the individual estimation methods.

    Full Text Available The aim of this study was to determine plant nutrients content and to in terms of soil variables their soil database and generate maps of their distribution on agricultural land in Central and Eastern Black Sea Region using geographical information system (GIS. In this research, total 3400 soil samples (0-20 cm depth were taken at 2.5 x 2.5 km grid points representing agricultural soils. Total nitrogen, extractable calcium, magnesium, sodium, boron, iron, copper, zinc and manganese contents were analysed in collected soil samples. Analysis results of these samples were classified and evaluated for deficiency, sufficiency or excess with respect to plant nutrients. Afterwards, in terms of GIS, a soil database and maps for current status of the study area were created by using inverse distance weighted (IDW interpolation method. According to this research results, it was determined sufficient plant nutrient elements in terms of total nitrogen, extractable iron, copper and manganese in arable soils of Central and Eastern Blacksea Region while, extractable calcium, magnesium, sodium were found good and moderate level in 66.88%, 81.44% and 64.56% of total soil samples, respectively. In addition, insufficient boron and zinc concentration were found in 34.35% and 51.36% of soil samples, respectively.

    2000-08-01

    The Capacity Building Seminar on 'Best Practice in Climate Technology and Energy Efficiency in Central and Eastern Europe', held 6-10 December 1999 in Marienthal/Ostritz in Germany, was a very successful event in the framework of the CLIMATE TECHNOLOGY INITIATIVE (CTI). One reason for that is that the seminar allowed delegates from 22 nations, from Kazakhstan to Estonia, come together for an exchange of opinions about 'Energy Efficiency and Climate Protection' and all related issues. A reason is that this seminar provided an excellent starting point for future networking in Central and Eastern Europe and Asia. The colleagues who got to know each other at the seminar will meet again in future workshops and seminars. They can now contact a colleague from abroad to get information about special questions of Energy Efficiency when they need it. A third reason - and the most important one for the entire co-operation within the CTI organisation - is the special character of the seminar as a starting point for multitude of activities on Energy Efficiency and Climate Protection. At the end of the Ostritz seminar eleven delegations stated that they would organise follow up workshops in their own countries to go deeper into the details and to co-operate on a higher level. It may be that these workshops will be followed by others in other European regions. (orig./GL)

    An ethnopharmaceutical study focused on domestic cosmetics, cosmeceuticals, and remedies to heal skin diseases traditionally used in the inland part of the Marches region (Central-Eastern Italy) has been conducted. At present, traditional knowledge concerning home-made phytocosmetics is represented by both the remnants of an orally transmitted folk heritage and also by new forms of knowledge, sometimes coming from popular phytotherapeutical books and the mass media (out of the scope of this survey), but also as a result of recent migration trends from Eastern Europe. We recorded approximately 135 cosmetic or cosmeceutical preparations prepared from more than 70 botanical species and a very few animal or mineral ingredients. Among the recorded preparations, developing a clear distinction amongst cosmetics, cosmeceuticals and pharmaceuticals for skin diseases is very problematic, confirming that in folk knowledge systems medicinal products for healing skin diseases and cosmetics have often been perceived as two poles of a continuum. Many of the quoted species represented well-known medicinal plants of the European phytotherapy, although we also recorded a few unusual plant taxa, which are briefly discussed under the perspective of their eventual phytochemical and/or phytopharmacological potentialities. Exotic drugs or precious essences, even native of the Mediterranean, were not quoted as ingredients for preparing perfumes and fragrances by the interviewees of the present study, thus indicating that popular cosmetic practices in rural Central Italy have taken a much separated path away from the cosmetic "know-how" of the aristocracy and high bourgeois classes of the last centuries.

    A common statistical procedure for estimating streamflow statistics at ungaged locations is to develop a relational model between streamflow and drainage basin characteristics at gaged locations using least squares regression analysis; however, least squares regression methods are parametric and make constraining assumptions about the data distribution. The random forest regression method provides an alternative nonparametric method for estimating streamflow characteristics at ungaged sites and requires that the data meet fewer statistical conditions than least squares regression methods.Random forest regression analysis was used to develop predictive models for 89 streamflow characteristics using Precipitation-Runoff Modeling System simulated streamflow data and drainage basin characteristics at 179 sites in central and eastern Montana. The predictive models were developed from streamflow data simulated for current (baseline, water years 1982–99) conditions and three future periods (water years 2021–38, 2046–63, and 2071–88) under three different climate-change scenarios. These predictive models were then used to predict streamflow characteristics for baseline conditions and three future periods at 1,707 fish sampling sites in central and eastern Montana. The average root mean square error for all predictive models was about 50 percent. When streamflow predictions at 23 fish sampling sites were compared to nearby locations with simulated data, the mean relative percent difference was about 43 percent. When predictions were compared to streamflow data recorded at 21 U.S. Geological Survey streamflow-gaging stations outside of the calibration basins, the average mean absolute percent error was about 73 percent.

    Farming domesticated millets, tending pigs, and hunting constituted the core of human subsistence strategies during Neolithic Yangshao (5000-2900 BC). Introduction of wheat and barley as well as the addition of domesticated herbivores during the Late Neolithic (∼2600-1900 BC) led to restructuring of ancient Chinese subsistence strategies. This study documents a dietary shift from indigenous millets to the newly introduced cereals in northcentral China during the Bronze Age Eastern Zhou Dynasty (771-221 BC) based on stable isotope analysis of human and animal bone samples. Our results show that this change affected females to a greater degree than males. We find that consumption of the newly introduced cereals was associated with less consumption of animal products and a higher rate of skeletal stress markers among females. We hypothesized that the observed separation of dietary signatures between males and females marks the rise of male-biased inequality in early China. We test this hypothesis by comparing Eastern Zhou human skeletal data with those from Neolithic Yangshao archaeological contexts. We find no evidence of male-female inequality in early farming communities. The presence of male-biased inequality in Eastern Zhou society is supported by increased body height difference between the sexes as well as the greater wealth of male burials.

    Full Text Available This paper presents the results of a survey of email users in different regions of Saudi Arabia about email SPAM. The survey investigated the nature of email SPAM, how email users in the eastern, western, central, southern and northern dealt with it, and the efforts made to combat it. It also investigated the effectiveness of existing Anti-SPAM filters in detecting Arabic and English email SPAM. 1,500 participants located in the eastern, western, central, southern and northern regions of Saudi Arabia were surveyed and completed surveys were collected from 1,020 of the participants. The results showed that there were different definitions for email SPAM based on different users’ opinions in Saudi Arabia. The results showed that the participants in the central and western regions were more aware of SPAM than the participants in other regions. The results revealed that the volume of email SPAM was different from region to another and the volume of SPAM received by the participants in the northern and central regions was larger than that received in other regions. The results indicated that the majority of email SPAM received by the participants in different regions was written in English. The results showed that the most common type of email SPAM received in Arabic was emails related to forums and in English was phishing and fraud, and business advertisements. The results also showed that a few participants in all regions responded to SPAM and the average of the participants who responded to SPAM was larger in the southern region than other regions. The results showed that most of the participants were not aware of Anti-SPAM programs and the participants in the central region were more aware of Anti-SPAM programs than the participants in other regions. The results showed that the participants in all regions estimated that the existing Anti-SPAM programs were more effective in detecting English SPAM than Arabic SPAM. The results showed that most

    Full Text Available Because Polish art history, that is, art history written by Polish scholars, has tended to be rather inward-looking as a whole, its first and most important school, that of Cracow, has not received the attention it deserves. The term ‘school’ is here used in a way akin to that of ‘Vienna School’. Cracow modern art history originated in the 1860s to 1880s in the small but culturally extremely vigorous capital of Austrian Poland, as a co-operation between the newly-founded art history section at the Academy of Sciences and the Department at the Jagiellonian University. It pursued two principal, interlinked aims: the investigation of Polish art and architecture and the use of new methods that were being developed in Western and Central Europe. What comes across most strongly is the constantly foregrounded ethos of scientific, empirical exactitude and the intense institutional togetherness. All are united in an absolute devotedness to their academic task. One of the results was the way in which recruitment has remained within the school until this day. It has to be remembered though that other Polish centres only started teaching the history of art after WW I. This article is a- preliminary attempt to characterise, firstly, some of the chief factors of institutionality and, secondly, some methodological aspects of the work of the two chief protagonists, Władysław Łuszczkiewicz and Marian Sokołowski.

  1. Estimating the Impact of Reducing Under-Nutrition on the Tuberculosis Epidemic in the Central Eastern States of India: A Dynamic Modeling Study.

    Full Text Available Tuberculosis (TB and under-nutrition are widespread in many low and middle-income countries. Momentum to prioritize under-nutrition has been growing at an international level, as demonstrated by the "Scaling Up Nutrition" movement. Low body mass index is an important risk factor for developing TB disease. The objective of this study was to project future trends in TB related outcomes under different scenarios for reducing under-nutrition in the adult population in the Central Eastern states of India.A compartmental TB transmission model stratified by body mass index was parameterized using national and regional data from India. We compared TB related mortality and incidence under several scenarios that represented a range of policies and programs designed to reduce the prevalence of under-nutrition, based on the experience and observed trends in similar countries.The modeled nutrition intervention scenarios brought about reductions in TB incidence and TB related mortality in the Central Eastern Indian states ranging from 43% to 71% and 40% to 68% respectively, relative to the scenario of no nutritional intervention. Modest reductions in under-nutrition averted 4.8 (95% UR 0.5, 17.1 million TB cases and 1.6 (95% UR 0.5, 5.2 million TB related deaths over a period of 20 years of intervention, relative to the scenario of no nutritional intervention. Complete elimination of under-nutrition in the Central Eastern states averted 9.4 (95% UR 1.5, 30.6 million TB cases and 3.2 (95% UR 0.7-, 10.1 million TB related deaths, relative to the scenario of no nutritional intervention.Our study suggests that intervening on under-nutrition could have a substantial impact on TB incidence and mortality in areas with high prevalence of under-nutrition, even if only small gains in under-nutrition can be achieved. Focusing on under-nutrition may be an effective way to reduce both rates of TB and other diseases associated with under-nutrition.

    An assemblage of 33 fossil pollen and spores, recovered from the 3600-m high Pislepampa locality of E. W. Berry, Eastern Cordillera, Bolivia, adds considerably to our knowledge of three aspects of the region in late Neogene time: (1) the paleovegetation, (2) the paleoclimate, and (3) the paleoelevation of the Central Andes. The plant microfossils recognized are Isoetes, Lycopodium (three types), Cnemidaria, Cyathea (three types), Grammitis, Hymenophyllum, Pteris, trilete fern spores (two types), Danaea, monolete fern spores (four types), Podocarpus, Gramineae, Palmae, Ilex, cf. Oreopanax, Cavanillesia, cf. Pereskia, Compositae (three types), Ericaceae, Tetrorchidium, and unknowns (three types). The diversity of the Compositae suggest that this flora has a maximum age around the Miocene-Pliocene boundary, that is, 6-7 million years. All members of the paleocommunity presently grow in the bosque montano húmedo (cloud forest) along the eastern slope of the Central Andes of Bolivia, which occurs between MATs (mean annual temperatures) of ∼10° and 20°C. The Pislepampa flora probably represents the lower limits of this forest because the fossil leaves collected by Berry from the same locality all have entire margins, suggesting that the flora grew near the cloud forest-tropical forest transition. Presently, the lower limit of the cloud forest forest has MATs of ∼20°C, a mean annual precipitation between 1000 and 1500 mm, and that part containing most of the identified genera of fossil pollen is found at elevations ∼1200-1400 m. These conditions are thus inferred for the Pislepampa flora; however, because of the uncertainty of the magnitude of global climate change and of possible changes in the ecological range of plant genera, we estimate an error of at least ±1000 m for the paleoelevation estimate. When the total uplift is corrected for probable amounts of erosionally driven isostatic rebound, the paleoelevation estimate suggests that from one-third to one

    Most researchers believe that anatomically modern humans (AMH) first appeared in Africa 160-190 ka ago, and would not have reached eastern Asia until ∼50 ka ago. However, the credibility of these scenarios might have been compromised by a largely inaccurate and compressed chronological framework previously established for hominin fossils found in China. Recently there has been a growing body of evidence indicating the possible presence of AMH in eastern Asia ca. 100 ka ago or even earlier. Here we report high-precision mass spectrometric U-series dating of intercalated flowstone samples from Huanglong Cave, a recently discovered Late Pleistocene hominin site in northern Hubei Province, central China. Systematic excavations there have led to the in situ discovery of seven hominin teeth and dozens of stone and bone artifacts. The U-series dates on localized thin flowstone formations bracket the hominin specimens between 81 and 101 ka, currently the most narrow time span for all AMH beyond 45 ka in China, if the assignment of the hominin teeth to modern Homo sapiens holds. Alternatively this study provides further evidence for the early presence of an AMH morphology in China, through either independent evolution of local archaic populations or their assimilation with incoming AMH. Along with recent dating results for hominin samples from Homo erectus to AMH, a new extended and continuous timeline for Chinese hominin fossils is taking shape, which warrants a reconstruction of human evolution, especially the origins of modern humans in eastern Asia.

    The present paper mainly studies the petroleum system of the Sufyan Depression in the Muglad Basin of central Africa and analyzes its control of hydrocarbon accumulation. On the basis of comprehensive analysis of effective source rock, reservoir bed types and source-reservoir-seal assemblages, petroleum system theory has been used to classify the petroleum system of the Sufyan Depression. Vertically, the Sufyan Depression consists of two subsystems. One is an Abu Gabra subsystem as a serf generating, accumulating and sealing assemblage. The other subsystem is composed of an Abu Gabra source rock, Bentiu channel sandstone reservoir and Darfur group shale seal, which is a prolific assemblage in this area. Laterally, the Sufyan Depression is divided into eastern and western parts with separate hydrocarbon generation centers more than 10 000 m deep. The potential of the petroleum system is tremendous. Recently, there has been a great breakthrough in exploration. The Sufyan C-1 well drilled in the central structural belt obtained high-yielding oil flow exceeding 100 tons per day and controlled geologic reserves of tens of millions of tons. The total resource potential of the Sufyan Depression is considerable. The central structural belt is most favorable as an exploration and development prospect.

    MEEREB is an informal network of rabies experts from the Middle East, Eastern Europe and Central Asia, seeking to eliminate rabies from the region. They met for the second time to review the current rabies situation, both globally and in their respective countries, highlighting current rabies control problems and potential solutions. Success stories in Latin America, in Western Europe, in some Asian countries, as well as in Croatia and Serbia prove that elimination of human rabies is achievable in the MEEREB region. It requires political willingness and cooperation of all stakeholders, including Ministries of Health and of Agriculture; adequate management of animal bites through post-exposure prophylaxis; pre-exposure prophylaxis for populations at high risk of rabies exposure, animal vaccination and humane control of stray dog populations. MEEREB members called for a regional initiative for rabies elimination in Eastern Europe and the Middle East. They are confident that the elimination of human rabies of canine origin can be achieved in the region through adopting a One Health approach, and that campaigns for rabies elimination will have significant benefit for public health, including strengthening the structure for control of other zoonoses.

    The objective of this paper is to share experience and provide updated information on Capacity Development in the Central and Eastern Europe/Balkan Countries (CEE/BC) region relevant to public health nutrition, particularly in creation of food composition databases (FCDBs), applying dietary intake assessment and monitoring tools, and harmonizing methodology for nutrition surveillance. Balkan Food Platform was established by a Memorandum of Understanding among EuroFIR AISBL, Institute for Medical Research, Belgrade, Capacity Development Network in Nutrition in CEE - CAPNUTRA and institutions from nine countries in the region. Inventory on FCDB status identified lack of harmonized and standardized research tools. To strengthen harmonization in CEE/BC in line with European research trends, the Network members collaborated in development of a Regional FCDB, using web-based food composition data base management software following EuroFIR standards. Comprehensive nutrition assessment and planning tool - DIET ASSESS & PLAN could enable synchronization of nutrition surveillance across countries.

    Generally, every several years, heavy amounts of rainfall trigger a large number of debris flows within the central and southern Appalachian Mountains of the Eastern United States. These types of landslides damage buildings, disrupt infrastructure, and occasionally injure and kill people. One of the first large debris flows was described in Pennsylvania in August 1779. The most destructive event occurred during August 19-20, 1969, in Nelson County, Va. During a period of 8 hours, 710 to 800 milimeters of rain triggered more than 3,000 landslides, killing more than 150 people. As the population increases in this region, future storms will likely increase the risks of property damage and loss of life. We provide a general overview of debris flows in the Appalachians, using a compilation of 19 storm events for which rainfall, duration of the storm, and descriptions of the resulting landslides have been substantially documented.

    Elementary educational facilities are one of the essential public service facilities in rural China. Based on case studies of two countylevel cities in central and eastern China, this paper explores issues regarding a rational allocation of elementary educational facilities in rural areas, including different allocation patterns and effects, and rural residents’ views on elementary educational facilities, as well as their preference when choosing schools. This paper, on the basis of empirical studies, concludes that relevant policies and planning strategies should be adjusted in accordance with the general trends of rural population being decreasing continuously and the student pool concentrating toward towns, so as to achieve an efficient and fair allocation of elementary educational facilities.

    The curvilinear E-W structures of the southern Thomson Orogen are approximately orthogonal to the general N-S structural trend of the Tasmanides of eastern Australia. The origin of these orogen-perpendicular structures and their implications to tectonic reconstructions of eastern Gondwana are not fully understood. Here we use geophysical data to unravel the geometry, kinematics and possible timing of major structures along the boundary between the Thomson Orogen and the southern Tasmanides (Delamerian and Lachlan orogens). Aeromagnetic data from the southern Thomson Orogen show WNW, E-W and/or ENE trending structural grains, corresponding to relatively long wavelength linear geophysical anomalies. Kinematic analyses indicate strike-slip and transpressional deformation along these geophysically defined faults. Structural relationships indicate that faulting took place during the Benambran (Late Ordovician to Middle Silurian) and Tabberabberan (late Early to Middle Devonian) orogenies. However, some of the described crustal-scale structures may have developed in the Cambrian during the Delamerian Orogeny. Interpretation of deep seismic data shows that the crust of the southern Thomson Orogen is substantially thicker than the Lachlan Orogen crust, which is separated from the Thomson Orogen by the north-dipping Olepoloko Fault. A major lithospheric-scale change across this boundary is also indicated by a contrast in seismic velocities. Together with evidence for the occurrence of Delamerian deformation in both the Koonenberry Belt and northeastern Thomson Orogen, and a significant contrast in the width of the northern Tasmanides versus the southern Tasmanides, it appears that the southern Thomson Orogen may represent the locus of orogen-perpendicular segmentation, which may have occurred in response to along-strike plate boundary variations.

    Full Text Available Various types of sensors-visible, passive night vision, infrared, synthetic aperture radar, etc can be used for desert surveillance. The surveillance capability of these sensors depends to a large extent, on various atmospheric effects, viz., absorption, scattering, aerosol, turbulence, and optical mirage. In this paper, effects of various atmospheric phenomena on the transmission of signals, merits and demerits of different means of surveillance under desert environmental conditions are discussed. Advanced surveillance techniques, ie, multisensor fusion, multi and hyperspectral imaging, having special significance for desert surveillance, have also been discussed.

    Granitoid gneisses are widespread in Precambrian metamorphic blocks of eastern segment of the Central Tianshan Tectonic Zone, and they have intrusive contact relationships with their metamorphic sedimentary country rocks of Proterozoic Xingxingxia and Kawabulag groups. Zircon U-Pb ages from a granodioritic gneiss (IW11-1) and a parametamorphic schist (W05-9) are determined at the Weiya area. Euhedral prismatic zircons from the granodioritic gneiss (IW11-1) provide U-Pb isotopic discordia intercept ages of 1218±17 Ma and 426±26 Ma, respectively, and euhedral prismatic zircons from the parametamorphic schist (W05-9) display U-Pb isotopic discordia intercept ages of 1216±74 Ma and 290±15 Ma, respectively. A whole-rock Sm-Nd isotopic isochron is determined in augen granitoid gneiss samples at the Ganggou-Kumishi area and we obtain the isochron age of 1142±120 Ma, and its εNd(t) = -4.3. These geochronological data suggest that these Precambrian metamorphic basement blocks within eastern segment of the Central Tianshan Tectonic Zone can be produced during 1140-1220 Ma, and occur a nearly homochronous metamorphism. Integrated to these geochronological data, Nd depleted mantle model ages (TDM) and epsilon Nd(t) values of these granitoid gneiss samples indicate that they can derive from mixing in various scales both magmas from mantle and crust sources at a late Mesoproterozoic active continental margin tectonic environment. Similarity in geochronology, Sm-Nd isotopic geochemistry between Weiya-Xingxingxia, Pargangtag and Ganggou-Kumishi areas suggests that they could be a bigger uniform metamorphic basement block, which could be formed by the assembly of the supercontinent Rodinia and be separated by late geological processes.

    The Serbo-Macedonian Massif (SMM) represents a composite crystalline belt within the Eastern European Alpine orogen, outcropping from the Pannonian basin in the north to the Aegean Sea in the south. The central parts of this massif (south-eastern Serbia) consist of the medium- to high-grade Lower Complex and the low-grade Vlasina Unit. Outcrop- and micro-scale ductile structures in this area document three major stages of ductile deformation. The earliest stage D1 is related to isoclinal folding, commonly preserved as up to decimetre-scale quartz-feldspar rootless fold hinges. D2 is associated with general south-eastward tectonic transport and refolding of earlier structures into recumbent metre- to kilometre-scale tight to isoclinal folds. Stages D1 and D2 could not be temporally separated and probably took place in close sequence. The age of these two ductile deformation stages was constrained to the Variscan orogeny based on indirect geological evidence (i.e. ca. 408-ca. 328). During this period, the SMM was involved in a transpressional amalgamation of the western and eastern parts of the Galatian super-terrane and subsequent collision with Laurussia. Outcrop-scale evidence of the final stage D3 is limited to spaced and crenulation cleavage, which are probably related to formation of large-scale open upright folds as reported previously. 40Ar/39Ar thermochronology was applied on hornblende, muscovite, and biotite samples in order to constrain the age of tectonothermal events and activity along major shear zones. These 40Ar/39Ar data reveal three major cooling episodes affecting the central SMM. Cooling below greenschist facies conditions in the western part of the Vlasina Unit took place in a post-orogenic setting (extensional or transtensional) in the early Permian (284 ± 1 Ma). The age of activity along the top-to-the-west shear zone formed within the orthogneiss in the Božica area of the Vlasina Unit was constrained to Middle Triassic (246 ± 1 Ma). This

  15. Industrial Growth Rates and Instability: An Historical Analysis of the Former Centrally Planned Economies of Eastern Europe

    Directory of Open Access Journals (Sweden)

    Evan E. ANDERSON

    2011-11-01

    Full Text Available One of the central tenets of socialism and central planning economics, as practiced by the East European countries, was that this organization of employment, production and activity could achieve higher growth rates than market economies. This paper presents an historical analysis of economic performance of seven countries: Bulgaria, Czechoslovakia, GDR, Hungary, Poland, Romania and Yugoslavia during the crucial period of socialism (1960-80. It studies the relationship between industry output growth rates and output instabilities in approximately twenty-five industries. Using empirically estimated models it was found that the instability (volatility of industry output increased with growth rates and at an increasing rate. Since instability creates substantial costs, these findings imply that the true value of income and product streams in East European countries, after discounting for instability, was lower than otherwise believed. A decomposition of instability into two sources, systemic structure versus operational implementation is suggested.

  16. The role of rodents in the ecology of Ixodes ricinus and associated pathogens in Central and Eastern Europe

    Full Text Available Rodents comprise more species than any other mammal order. Most rodents are considered keystone species in their ecological communities, hence the survival of many other species in the ecosystem depend on them. From medical point of view, this is particularly important for rodent-dependent pathogens. In the particular case of tick-borne diseases, rodents are important as hosts for vector ticks and as reservoir hosts (Lyme borreliosis, human granulocytic anaplasmosis, Crimean-Congo hemorrhagic fever, Tick-borne relapsing fevers, tick-borne rickettsioses, babesiosis. Community and population ecology of rodents was shown to be correlated with disease ecology in the case of many tick-borne diseases. In Eastern Europe, several adult hard-tick species use rodents as their principal hosts: Ixodes apronophorus, I. crenulatus, I. laguri, I. redikorzevi, I. trianguliceps. However, the majority of ticks feeding on rodents are immature stages of ticks which as adults are parasitic on larger mammals. Larvae and nymphs of I. ricinus, the most abundant and medically important tick from Europe, are commonly found on rodents. This is particularly important, as many rodents are synanthropic and, together with other micromammals and birds are often the only available natural hosts for ticks in urban environments. This work reviews the correlated ecology of rodents and Ixodes ricinus.

    Eight stratigraphic sections, located in northeastern part of the Sahel area of Tunisia recorded evidences of "Lago-Mare" episode and events related to the Messinian-Late Pliocene interval. A comparison with previous studies carried on sections from neighboring areas and boreholes data drilled within the Gulf of Hammamet and the Gulf of Gabès, is conducted and gives useful information to characterize the Late Messinian to Late Pliocene events. The most notable feature distinguished in the studied area consists on the lack of gypsum, commonly recorded in relation with the crucial event of the Messinian Salinity Crisis. However, only lagoonal deposits, bearing messinian brackish fauna, are encountered. These sediments are usually attributed to the "Segui" formation or the so called "Mio-Pliocene continental". Thin sections samples and field observations have recognized sands, marls, clays, lacustrine limestone, some gypsum lenses, mud-cracks, lignite and Messinian brackish fauna. Similar deposits were previously described in the Kechabta basin from the Northern Tunisia and in some wells from the Gulf of Gabès and the Gulf of Hammamet. We suggest that all these facies belong to the coeval of the "Lago-Mare" facies within Eastern and Western Mediterranean basins (e.g. Sicily, Mallorca, Libya and Cyprus). Finally, four major erosional surfaces have been recorded within the Late Messinian-Late Pliocene deposits, aged post-Tortonian, intra-Messinian, Late Messinian and intra-Pliocene times. They seem to be the result of local tectonic uplifts and eustatic fluctuations.

  2. Endemic and threatened tetrapods in the restingas of the biodiversity corridors of Serra do Mar and of the central da Mata Atlântica in Eastern Brazil

    Directory of Open Access Journals (Sweden)

    C. F. D Rocha

    Full Text Available Biodiversity corridors comprise a mosaic of land uses connecting fragments of natural forest across a landscape. Two such corridors have been established along the eastern coast of Brazil: the Serra do Mar and the Central da Mata Atlântica corridors, along which most of the coastal plains are restinga areas. In this study, we analyze the present status of the endemic and endangered terrestrial vertebrates of both corridors. We sampled 10 restingas in both corridors, recording species of amphibians, reptiles, birds, and mammals. Some restingas harbor a relatively large number of endemic species, and two main regions of endemism can be identified along the restingas of both corridors: the coastal restingas from northern Espírito Santo State to southern Bahia State (between Linhares, ES, and Trancoso, BA, and the coastal region between the restingas of Maricá and Jurubatiba, Rio de Janeiro State. Six species of terrestrial vertebrates considered threatened with extinction are found in the restingas of Serra do Mar and Central da Mata Atlântica biodiversity corridors (Liolaemus lutzae, Formicivora littoralis, Mimus gilvus, Schistochlamys melanopis, and Trinomys eliasi. The region located between the restinga of Maricá and that of Jurubatiba is of special relevance for the conservation of vertebrate species of the restingas of the corridors because a considerable number of threatened species of terrestrial vertebrates are found there. We strongly recommend efforts to develop checklists of threatened faunas for the States of Espírito Santo and Bahia.

  3. Seismic velocity structure of the crust and shallow mantle of the Central and Eastern United States by seismic surface wave imaging

    Pollitz, Fred; Mooney, Walter D.

    2016-01-01

    Seismic surface waves from the Transportable Array of EarthScope's USArray are used to estimate phase velocity structure of 18 to 125 s Rayleigh waves, then inverted to obtain three-dimensional crust and upper mantle structure of the Central and Eastern United States (CEUS) down to ∼200 km. The obtained lithosphere structure confirms previously imaged CEUS features, e.g., the low seismic-velocity signature of the Cambrian Reelfoot Rift and the very low velocity at >150 km depth below an Eocene volcanic center in northwestern Virginia. New features include high-velocity mantle stretching from the Archean Superior Craton well into the Proterozoic terranes and deep low-velocity zones in central Texas (associated with the late Cretaceous Travis and Uvalde volcanic fields) and beneath the South Georgia Rift (which contains Jurassic basalts). Hot spot tracks may be associated with several imaged low-velocity zones, particularly those close to the former rifted Laurentia margin.

    2003-03-01

    This comparative discourse on land reclamation in the Central and East European lignite mining regions is based on a complex analysis of the prevailing natural, geological, technological and social conditions. Considering the above conditions, the reclaimed land in the mined-out lignite mines of Central and Eastern Europe will predominantly be used as forests, although farming is also possible under particularly suitable conditions. Some of the land is given over to recreational purposes and integrated into the relevant landscape. Large lakes in residual holes of former lignite mines have only been created in Germany so far, where the special requirements of nature preservation have also been given attention. As regards the planning and financing regulations and the regulations coordinating the use of the post-mining land, there are differences between the individual countries which must be attributed to the rather diverse legal conditions. In general, the tasks associated with recultivation are defined similarly, are based on scientific investigations and are implemented at a very high level. The exchange of experience should be continued also in the future. (orig.)

  5. Microhabitat occupation and functional morphology of four species of sympatric agamid lizards in the Kyzylkum Desert, central Uzbekistán

    Directory of Open Access Journals (Sweden)

    Clemann, N.

    2008-12-01

    Full Text Available We examined microhabitat occupation and functional morphology of four sympatric agamid lizards (Phrynocephalus helioscopus helioscopus, P. interscapularis, P. mystaceus galli and Trapelus sanguinolentus at three sites in the arid zone of central Uzbekistan. At two sites located in sand dunes, substrate attributes played a key role in habitat selection by three syntopic species. At a third flat, stony site, P. helioscopus selected habitat non–randomly, tending to occur close to sparse, low vegetation. Syntopic taxa were separated in morphospace, and there was a trend for taxa with proportionally longer limbs to have faster field escape speeds. Field escape distances and predator avoidance tactics differed between species, with two main escape strategies (crypsis or sand–diving following an escape sprint. We caution that broad–scale threatening processes such as over–grazing and salinity may be having a detrimental effect on microhabitat features important to terrestrial reptiles in Uzbekistan.

    SummarySapflow measurements were carried out in a larch forest in eastern Siberia, an area of wide permafrost distribution. Canopy transpiration and canopy conductance were scaled up from these values. The objective was to analyze the relationship between environmental variables, mainly vapour pressure deficit ( D), soil moisture and soil thawing rate with canopy transpiration and canopy conductance. Maximum sapflow rate was 42.4 kg d -1 tree -1 with bigger trees showing a more accentuated response to environmental changes. Canopy transpiration ( Ec) showed inter-annual variability, with a maximum value of 1.7 mm d -1 in 2003 and 1.2 mm d -1 in 2004. Soil moisture was higher in 2003 because of higher precipitation (230 mm in 2003 compared to 110 mm in 2004 for the total growing season). Maximum soil thawing rate in 2003 and 2004 was 140 cm and 120 cm, respectively, because of different air temperature, soil water content and precipitation regime among other factors. Canopy conductance ( gc) was positively correlated with D during fine weather and well-watered days in both years. On the other hand, canopy conductance was well correlated with soil moisture ( R2 = 0.83) in the upper layers (20-30 cm depth) during 2003 (wet year) but not in 2004 (dry year), representing its strong but limited control over water fluxes from the forest. By comparison with other studies in this region, canopy transpiration is estimated to contribute to almost 50% of the total forest evaporation, highlighting the important role of understorey transpiration in permafrost regions. Our results show that it is not only the impermeability of permafrost with the property of keeping soil moisture in the thin active layer but it is also the slow soil thawing rate that plays the important role of controlling the amount of water available for trees roots in the upper soil layers during dry years.

    The U.S. Geological Survey collaborated with international colleagues to assess undiscovered resources in porphyry copper deposits in the Central Asian Orogenic Belt and eastern Tethysides. These areas host 20 known porphyry copper deposits, including the world class Oyu Tolgoi deposit in Mongolia that was discovered in the late 1990s. The study area covers major parts of the world’s largest orogenic systems. The Central Asian Orogenic Belt is a collage of amalgamated Precambrian through Mesozoic terranes that extends from the Ural Mountains in the west nearly to the Pacific Coast of Asia in the east and records the evolution and final closure of the Paleo-Asian Ocean in Permian time. The eastern Tethysides, the orogenic belt to the south of the Central Asian Orogenic Belt, records the evolution of another ancient ocean system, the Tethys Ocean. The evolution of these orogenic belts involved magmatism associated with a variety of geologic settings appropriate for formation of porphyry copper deposits, including subduction-related island arcs, continental arcs, and collisional and postconvergent settings. The original settings are difficult to trace because the arcs have been complexly deformed and dismembered by younger tectonic events. Twelve mineral resource assessment tracts were delineated to be permissive for the occurrence of porphyry copper deposits based on mapped and inferred subsurface distributions of igneous rocks of specific age ranges and compositions. These include (1) nine Paleozoic tracts in the Central Asian Orogenic Belt, which range in area from about 60,000 to 800,000 square kilometers (km2); (2) a complex area of about 400,000 km2 on the northern margin of the Tethysides, the Qinling-Dabie tract, which spans central China and areas to the west, encompassing Paleozoic through Triassic igneous rocks that formed in diverse settings; and (3) assemblages of late Paleozoic and Mesozoic rocks that define two other tracts in the Tethysides, the 100

    In Central & Eastern Europe, the democratization and marketization are in a malignant interactive relationship when both of them are caught in difficult positions. Marketization during political unrest and democratization under economic recession bring adverse effects to each other and intensify difficulties for each other. However, the two sides have a benign interaction when both democratization and marketization processes are in smooth development. The higher degree of democratization and marketization makes the two sides promote each other and makes them step forward together. Therefore, generally speaking, countries with fast democratization, solid democratic systems and stable political situation have a faster pace of marketization, a more mature market economy and more rapid economic development. In addition to the compatibility between democratic systems and market economies, the positive relationship between the democratization and marketization of Central & Eastern Europe also benefits from the regulating and driving functions of the European Union.%中东欧国家的民主化与市场化遭遇困境时呈恶性互动关系,政治动荡中的市场化和经济衰退中的民主化给彼此带来不利影响,加剧各自的困难;民主化与市场化发展顺畅时呈良性互动关系,民主化和市场化程度越高,越是相互促进,共同进步。因此,民主化进度较快、民主制度较为巩固、政局较为稳定的国家一般也是市场化步子较大、市场经济较为成熟、经济发展较为迅速的国家。中东欧国家民主化与市场化的这种正相关关系得益于民主制度与市场经济之间的兼容性,更得益于欧盟在其中所起的规范和推动作用。

  10. Timing and conditions of metamorphism and melt crystallization in Greater Himalayan rocks, eastern and central Bhutan: insight from U-Pb zircon and monazite geochronology and trace-element analyses

    Within the eastern Himalaya in central and eastern Bhutan, Greater Himalayan (GH) rocks are interpreted to have been thickened by the Kakhtang thrust (KT). In order to understand the metamorphic and exhumation history of the GH and to evaluate the structural significance of the KT, zircon and monazite from twenty samples were analyzed by laser-ablation split-stream ICPMS. In eastern Bhutan, zircon and monazite from samples collected in the KT hanging wall revealed ca. 36-28 Ma metamorphism. Subsequently, the initiation of melt crystallization shows a trend with structural distance above the KT, with early melt crystallization (ca. 27 Ma) in the structurally highest samples and younger melt crystallization (ca. 16 Ma) for leucosomes within the KT zone. Melt crystallization was protracted and continued until ca. 14-13 Ma in both the KT hanging wall and the footwall. In comparison, in central Bhutan, two leucosomes revealed extended melt crystallization from ca. 31 to 19 Ma. The youngest zircon dates from samples exposed structurally above and below the KT are similar, indicating that the KT was not as significant of a structure as other fault systems to which it has been correlated. However, the younging trend in the initiation of melt crystallization with decreasing structural distance above the KT argues that progressive underplating of ductile material assisted in the initial emplacement of the GH unit in central and eastern Bhutan. The KT likely represents a minor shear zone that aided in this underplating process.

    New mapping, geochemistry, and 17 U–Pb SHRIMP zircon ages from rocks of the Sirwa, Bou Azzer–El Graara, and Jebel Saghro inliers constrain the Neoproterozoic evolution of the eastern Anti-Atlas during Pan-African orogenesis. In the Sirwa inlier, Tonian quartzite from the pre Pan-African passive margin deposits of the Mimount Formation contains detrital zircon derived entirely from the West African Craton (WAC), with most grains yielding Eburnean Paleoproterozoic ages of about 2050 Ma. Cryogenian Pan-African orogenic activity (PA1) from about 760 to 660 Ma included northward-dipping subduction to produce a volcanic arc, followed by ophiolite obduction onto the WAC. In the Bou Azzer–El Graara inlier, calc-alkaline granodiorite and quartz diorite, dated at 650–646 Ma, are syn- to post-tectonic with respect to the second period of Pan-African orogenesis (PA2), arc-continent accretion, and related greenschist facies metamorphism. Slab break-off and lithospheric delimination may have provided the source for the supra-subduction calc-alkaline plutons. At about 646 Ma, quartz diorite intruded the Tiddiline formation placing an upper limit on molassic deposition. Widespread Ediacaran high-K calc-alkaline to shoshonitic plutonism and volcanism during the final stage of Pan-African orogenesis (PA3) occurred in a setting related to either modification of the margin of the WAC or formation of a continental volcanic arc above a short-lived southward-dipping subduction zone. In the Saghro inlier, eight plutonic rocks yield ages ranging from about 588 to 556 Ma. Sampled plutonic rocks previously considered to be Cryogenian yielded Ediacaran ages. Peraluminous rhyolitic volcanic rocks in the lower part of the Ouarzazate Supergroup, including ash-flow tuffs of the Oued Dar’a caldera, yield ages between about 574 and 571 Ma. The Oued Dar’a caldera developed in a pull-apart graben produced by a left-step in a northeast-trending, left-lateral strike-slip fault zone, and

    Full Text Available Societal conditions for early and high rates of childbearing were replaced by conditions generating late and low levels of fertility common in Western countries. Central among factors shaping the latter behaviour (job insecurity, unstable partnership relationships, expensive housing, and profound changes in norms, values and attitudes were the following: increasing proportions of young people were acquiring advanced education, a majority of women were gainfully employed, yet women were performing most household maintenance and childrearing duties. Two theories prevailed to explain what caused changes in family formation and fertility trends. One argues that the economic and social crises were the principal causes. The other considered the diffusion of western norms, values and attitudes as the prime factors of change. Neither reveals the root cause: the replacement of state socialist regimes with economic and political institutions of contemporary capitalism. The extraordinarily low period TFRs around 2000 were the result of low fertility of older women born around 1960 overlapping with low fertility of young women born during the 1970s.

    Full Text Available Early Triassic carbonate outcrops were studied in the central sector of the Hăghimaş Syncline with regard to stratigraphy, microfacies and facies interpretation.This is the first microfacies study of these deposits. Early Triassic carbonates in the Hăghimaş Syncline are represented by two stratified successions: limestones and dolomites. The limestones overlie very rarely the detritic basal deposits (Induan which marks the beginning of the alpine transgression. The stratified dolomites underlie frequently the Early Anisian massive dolomites. The contact between the stratified limestones and stratified dolomites is only exposed on Calu brook outcrop (the western flank of the Hăghimaş Syncline. The age of the investigated carbonates is Olenekian, based on the occurrence of Meandrospira pusilla biozone (in limestones. The foraminifera are very scarce in dolomites, represented mostly by Earlandia taxa. Microfacies data indicate the existence of a carbonate platform. The Olenekian carbonates yield a broad spectrum of microfacies types, predominantly micrites and biomicrites with foraminifera associated with echinoderms, ostracods, radiolarians, calcitized gastropods etc. These facies types are also known from the carbonate platforms in other parts of the Tethys.

    To constrain the Early-Middle Paleozoic tectonic evolution of the south-eastern segment of the Central Asian Orogenic Belt (CAOB), we undertook zircon U-Pb dating and analyzed major and trace elements and zircon Hf isotope compositions of Late Cambrian to Middle Devonian igneous and metasedimentary rocks in central Jilin Province, NE China. LA-ICP-MS zircon U-Pb dating indicates that the Early-Middle Paleozoic magmatism in central Jilin Province can be divided into four episodes: Late Cambrian (ca. 493 Ma), Middle Ordovician (ca. 467 Ma), Late Ordovician-Early Silurian (ca. 443 Ma), and Late Silurian-Middle Devonian (425-396 Ma). The progression from subduction initiation to maturity is recorded by Late Cambrian low-K tholeiitic meta-diabase, Middle Ordovician medium-K calc-alkaline pyroxene andesite, and Late Ordovician to Early Silurian low-K tonalite, which all have subduction-related characteristics and formed in an evolving supra-subduction zone setting. Late Silurian to Middle Devonian calc-alkaline igneous rocks, with the lithological association of granodiorite, monzogranite, rhyolite, dacite, and trachydacite, show progressively increasing K2O contents from medium K to shoshonite series. Furthermore, the Early-Middle Devonian monzogranites are characterized by high K2O, Sr/Y, and [La/Yb]N values, indicating they were generated by the melting of thickened lower crust. These results suggest a transition from subduction to post-orogenic setting during the Late Silurian-Middle Devonian. Our interpretation is supported by the maximum age of molasse deposition in the Zhangjiatun member of the Xibiehe Formation. Overall, we suggest that Late Cambrian tholeiitic meta-diabase, Middle Ordovician pyroxene andesite, and Late Ordovician-Early Silurian tonalite formed above the northward-subducting and simultaneously seaward-retreating of Paleo-Asian Ocean plate. Subsequently, the northern arc collided with the North China Craton and post-orogenic extension occurred

    The cosmic star formation rate, AGN activity, galaxy growth, mass assembly and morphological differentiation all culminate at redshift $\\sim 2$. Yet, the redshift interval $1.4\\lsim z\\lsim 3$ is harder to explore than the closer and the more distant Universe. In spite of so much action taking place in this spacetime portion of the Universe, it has been dubbed the ``Redshift Desert'', as if very little was happening within its boundaries. The difficulties encountered in properly mapping the galaxy populations inhabiting the Desert are illustrated in this paper, along with some possible remedy.

  17. New finding of micro-diamonds in eclogites from Dabie-Sulu region in central-eastern China

    2003-01-01

    Micro-diamonds were only found ten years ago in eclogite associated with marble at Xindian in the Dabie Mountains. This paper reports our new finding of micro-diamonds not only in eclogites at Maobei in the Sulu region and at Xindian and Laoyoufang in the south part of the Dabie Mountains (South Dabie), but also in eclogites at Baizhangya and Huangweihe in the northern part of the Dabie Mountains (North Dabie) that has usually been considered not to experience ultrahigh pressure metamorphism. Except the micro-diamond at Huangweihe that was found from the artificial heavy sands of zircons used for isotopic dating, the micro-diamonds from other localities were identified in thin sections of the eclogites. Besides a few interstitial grains, most of the micro-diamond grains in thin sections occur as inclusion in garnet. Three crystals of micro- diamond at Maobei in the Sulu region are sized in 120, 60 and 30 (m, respectively. Crystal forms look like octahedron and the composite of octahedron and hexahedron. The largest micro-diamond crystal comes from Xindian, which is measured to be 180 (m in diameter with distinct zonal structure and inclusions. The zonal structure occurs as an inclined octahedron inside rounded by an incomplete hexagonal girdle. A smaller micro-diamond inclusion occurs inside the central octahedron, and a larger graphite inclusion is within the outer zone. The Laoyoufang micro-diamond is partially retrograded to graphite. Micro-diamond from the Baizhangya eclogite in the ultramafic rock belt of North Dabie is an aggregate of 70 (m×90 (m in size. All the micro-diamonds are confirmed by the Raman spectrum analysis. The occurrence of the micro-diamonds from the eclogites in the ultramafic rock belt of North Dabie demonstrates that this region was also subjected to ultrahigh pressure metamorphism as well as the South Dabie did.

    This paper examines newspaper coverage of the impact on NHS Scotland of recent Central and Eastern European immigration. It follows rising public interest in the impacts of 'record' and 'unexpected' levels of migration after the 2004 and 2007 European Union (EU) enlargements. We reviewed reporting in six Scottish newspapers during 2004-2008 to track underlying themes within their coverage of EU migration. The framework of Social Representations Theory (SRT) was used to analyse how migration's impact was conceptualised and explained. This research shows that portrayal of migrants posing a threat to the NHS (e.g. European staff with inadequate qualifications), has increased in frequency but changed in nature over the past 4 years. Meanwhile, reports have also portrayed themes of reassurance (e.g. NHS management control) to allay societies' fears. The overall pattern is of representations of threat in the Scottish press being closely followed by those of reassurances. The most important reassurances relate to Scottish socioeconomic conditions, which raises questions might be seen in other UK newspapers as well as what will happen in Scotland if A8 migration decreases.

    Full Text Available Perceived causes, diagnosis and treatment of redwater (babesiosis and gallsickness (anaplasmosis in cattle by livestock farmers in communal areas of the central Eastern Cape Province were investigated by means of participatory methods, semi-structured interviews and a questionnaire survey. Most livestock owners relate the causes of these diseases to excessive grazing of lush green grass, which is thought to bring about an accumulation of bile in the body. The majority of livestock owners diagnose gallsickness and redwater on the basis of presenting signs and post mortem findings. Eighty nine percent of a total of 343 livestock owners participating in the study claimed to administer herbal remedies to treat the 2 tick-borne diseases; 75 % of these combine herbal remedies with conventional medicines and 25 % use herbal remedies only. Application of herbal remedies was reportedly aimed mainly at the removal of excess bile. However, some plant species used to prepare herbal remedies are reported to possess activities ranging from anti-inflammatory, analgesic, antimicrobial, anti-pyretic and purgative, and may be effective in the treatment of gallsickness and redwater. A lack of understanding of the causes and transmission of gallsickness and redwater, leading to ill-directed treatment, and widespread deviation from the directions of use when administering conventional medicines, were identified as problems that could be addressed by farmer training and the supply of appropriate information.

However, in times of geopolitical reconfiguration of ranking supremacy, economic events held on a stage that sums up all the world, with everything that means material resources, financial resources, polarized areas of intervention, causation so "equation", sometimes with many and unpredictable variables, may not be so easy to solve it. The measurements and econometric calculation are indisputable correct, analysis and the economic forecasts must be accompanied by correct investment strategies on international road map being important to not overlook tension that may weaken national strategy. Informational abundance is as dangerous, or more correctly ineffective, like is the shortage of information.

    The present study deals with the assessment of groundwater with respect to the main hydrological processes controlling its chemistry and its subsequent impact on groundwater quality for drinking and irrigation purposes in the eastern part of the Central Arabian graben and trough system. Groundwater samples were collected from 73 bore wells tapping the Cretaceous Biyadh and Wasia sandstone aquifers. The main groundwater facies in the area belong to the mixed Casbnd Mgsbnd SO4/Cl type and the SO4sbnd Cl type. Prolonged rock water interaction has resulted in high TDS (average of 2131 mg/l) and high EC (average of 2725 μS/cm) of the groundwater. The average nitrate (56.38 mg/l) value in the area is higher than the WHO prescribed limits of 50 mg/l in drinking water and is attributed to agricultural activities. The Drinking Water Quality Index (DWQI) shows that 33% of the water samples fall within the excellent to good category whereas the remaining samples fall in the poor to unsuitable for drinking category. In terms of Sodium Adsorption Ratio (SAR), Sodium percentage (Na %) and Residual Sodium Carbonate (RSC) the groundwater is suitable for irrigation however the high salinity values can adversely affect the plant physiology.

    The retrofitting of old power plants in central and eastern Europe is a task of enormous dimensions and great importance. As all governments there are low in funds, measures to extend service life of the plants are an essential economic alternative to erecting new plants. The demand for retrofitting work opens up good marketing chances for power plant manufacturers of the West on the basis of cooperation agreements with domestic plant manufacturers in those countries, as is shown by the activities of Siemens/KWU. Now as before, creativity is much in demand for solving a substantial problem, the financing of retrofitting projects. (orig./CB) [Deutsch] Die Rekonstruktion alter Kraftwerke in Mittel- und Osteuropa ist eine Aufgabe von enormem Ausmass und grosser Bedeutung. Lebensdauerverlaengernde Massnahmen sind angesichts knapper Finanzen eine wirtschaftliche Alternative zum Anlagenneubau.

    The amalgamation of the Western Gondwana (including the Greater Gondwana supercraton) occurred at 600 Ma during the Brazilian - Pan African orogeny. A plate junction related to this event is marked by the Transbrazilian lineament which separates the South American continent into two sectors: the Eastern Paraguay-Brazilian and Central Andean domains. An overview of the geodynamic data from these two sectors indicates that the two domains were subjected to distinct evolutions from the Proterozoic to the present. The Andean domain is characterized by long-lived subduction processes linked to the convergence and consequent collision of microplates since the Middle Proterozoic (western Amazonian Craton) with a peak at about 600-580 Ma. The Paraguay-Brazilian domain remained relatively stable but was affected by extension episodes that reactivated ancient (Early and Middle Proterozoic) suture zones. These different geodynamic evolutions seem to reflect broadly distinct mantle compositions. In the subduction zones of the Andean domain the mantle was deeply modified by metasomatic processes following the subduction of oceanic plates. Consequently, the Andean type magma sources show a clear HIMU imprint inherited from the MORB, whereas the Paraguay-Brazilian sector shows a prevalent EMI and subordinate EMII character. The petrological data mainly from Mesozoic and Cenozoic magmatic events in the two sectors are reviewed to investigate the current mantle plume and mantle dome models for the uprising of the asthenospheric (or sub-lithospheric) material.

  6. The impact of the financial crisis under the effects of increasing global economic interdependence. The case of Eastern and Central Europe Economies

    Full Text Available The technological progress that arose in areas such as transportation, communication and information exchange has led to a series of consequences that forced national economies to converge into a global, market based economy. In addition to the aforementioned causes, increased liberalisation amidst financial markets has supplemented the initiation of this metamorphosis that had several benefits in terms of general commercial exchange (trade, capital flows, and investment opportunities for business organisations. Simultaneously with the financial leverage resulted from the expansion of these interconnections, a series of channels that are detrimental to the financial welfare of entities has emerged, which, in consequence elevated the vulnerability and susceptibility to external economic shocks. The major debate elicited by this trade-off mainly concerns the costs and benefits of the international liberalisation of capital flows and trade. The purpose of this article is to examine the methods through which globalisation has affected the expansion of the international financial crisis back in 2008, by identifying and assessing the subsequent transfer routes, to and from the United States, where it was initially triggered. This article also aims to evaluate the repercussions experienced by Central and Eastern Europe and how they re-established economic growth following the financial crisis.
