  1. Spain and the Western Sahara: the Political Party Dimension

    Directory of Open Access Journals (Sweden)

    Jordi Vaquer i Fanés

    2007-12-01

    Full Text Available Since the Spanish army’s hasty withdrawal from Western Sahara in 1975, the two main parties since Spain acquired its democracy have differed over what stance should be taken with respect to the Sahara issue. The aim of this article is to establish to what extentthis is the result of the opposing government/opposition dynamic and how far it is a result of the parties’ own stances, by analysing the evolution of their attitudes and approaches with respect to the Sahara issue. The hypothesis is that the Spanish parties’ position with respect to Algeria and Morocco was initially very much determined by their view of the Sahara issue, but that there has been an inversion of this attitude. Thus at present, opposing stances on the Sahara issue are mainly the result of different views on Spain’s interests in the Maghreb region and, above all, of different ideas about which country Morocco or Algeria should benefit most from bilateral relations.

  2. Ammonoids from the Dalle des Iridet of the Mouydir and Ahnet (Central Sahara and the Formation d'Hassi Sguilma of the Saoura Valley (Late Tournaisian–Early Viséan; Algeria

    2010-02-01

    Full Text Available Four ammonoid species are described from the Early Carboniferous (Mississippian Iridet Formation of the Ahnet and Mouydir (Central Sahara, Algeria; three of which are new: Eurites temertassetensis n. sp., Trimorphoceras teguentourense n. sp., and Trimorphoceras azzelmattiense n. sp. The species can be attributed to the North African Ammonellipsites-Merocanites Assemblage (Fascipericyclus-Ammonellipsites Genus Zone; Late Tournaisian to Early Viséan. Additionally, the two new species Ammonellipsites sguilmensis n. sp. and Muensteroceras beniabbesense n. sp. are described from the time equivalent Hassi Sguilma Formation of the Saoura Valley (north-western Algeria. doi:10.1002/mmng.200900012

  3. Adolf Sandoz, an Orientalist Painter in Algeria

    Directory of Open Access Journals (Sweden)

    Wójcik, Agata

    2017-04-01

    Full Text Available Adolf Karol Sandoz was a 19th-century Polish artist who spent his life and developed his artistic career in France. In Paris, he studied painting and architecture, and worked as a professional illustrator. He can also be linked with a circle of artist-travellers, who searched for new sources of inspiration in the Orient. In 1879 and 1881, Sandoz travelled in Algeria. He described his impressions from the first journey in vividly written memoires published by the Krakow journal "Czas". His travels inspired several genre paintings, including: "Interior of a house in Biskra", "Dancer from the Uled Nail tribe", "Arab woman by a cradle", "Morning in the Sahara", "Evening in the Sahara", "Oasis", "On the Oued riverbank at El Kantara oasis", and "Sheik Mistress of El Kantara". At present, his works emerge at art auctions, are known from reproductions, or only from descriptions. Sandoz exhibited in Paris, Warsaw, Krakow, and Lviv, where he was appreciated by art critics. The aim of this article is to introduce Sandoz’s journey to Algeria, analyse his paintings with exotic subject matter, and locate them within a wider context of orientalist painting. It will also present the history of artistic travel to Algeria undertaken by 19th-century painters, including those from Poland.

  4. Occurrence of fluororichterite and fluorian biotite in the In Tifar trachyte neck (Tazrouk district, Hoggar volcanic province, Sahara, Algeria)

    Science.gov (United States)

    Azzouni-Sekkal, Abla; Bonin, Bernard; Ben El Khaznadji, Riad

    2013-09-01

    The unusual occurrence in the In Tifar trachyte neck (Tazrouk district, Hoggar volcanic province, Sahara, Algeria) of the fluorian biotite-fluororichterite association is presented. The two mineral species were previously unknown in the Hoggar and their association is uncommon worldwide. Ti-rich biotite has 28-40% OH sites occupied by fluorine, hence the use of the modifier "fluorian". Sodic-calcic fluororichterite has more than 55% OH sites filled by fluorine, hence the use of the prefix "fluoro". Well-defined F-Mg affinities are documented in both cases, while Cl remains very low. Temperatures are estimated roughly at 775-700 °C at low pressures. The fluorian biotite → fluororichterite sequence of crystallisation implies increasingly high fH2F2/fH2O ratios in metaluminous H2O-dominated evolving to peralkaline F-enriched fluids.

  5. ORGANIZED CRIME IN ALGERIA: TYPOLOGIES AND CHARACTERISTICS

    Directory of Open Access Journals (Sweden)

    Hatem BENAZOUZ

    2017-12-01

    Full Text Available This essay tries to analyse the phenomenon of national and transnational organized crime, which focuses the attention of several countries, governments, security and judicial apparatus throughout the world, on its threat to world stability and its destructive impact on the economic, social and security plans. The various aspects of this phenomenon are described through the follow-up of the various stages in which organized crime in Algeria developed. Its impact on the stability of neighbour countries is also worth mentioning, because is increasing in intensity and diversifying national and transnational criminal activities.

  7. Impact of the Invasion of Modern Irrigation Systems in the Oasis of Lahmar, South Western Algeria

    OpenAIRE

    Cherif Rezzoug; Boualem Emini; Saed Hamoudi

    2016-01-01

    For centuries, the oasis dwellers of the Algerian Sahara exploit the groundwater through the use of traditional techniques such as foggaras (traditional technique of irrigation in the Algerian southwest), and wells of chadouf (pendulum wells). In the oasis of Lahmar, in Southwest Algeria, the farmers use foggaras (known by the name of foggaras ain - foggaras of source) to irrigate their fields. Nowadays though, due to the indiscriminate use of modern systems (boreholes and pump...

  8. Water safety plan at the Saharawi refugee camps in Tindouf (Algeria

    Directory of Open Access Journals (Sweden)

    R. García

    2018-01-01

    Full Text Available Since 1975, about 165,000 people from Western Sahara are living as refugees in the Sahara Desert near Tindouf (Algeria. Available water resources come from deep boreholes located up to tens of kilometers away from the settlements of the population, bulk water is treated in reverse osmosis plants and by chlorination systems and, after, distributed through a network of taps and water tankers. Water supply system complexity and extreme conditions force the elaboration of a Water Safety Plan, aiming to guarantee appropriate provision and quality of water. The plan follows a risk assessment methodology and establishes control mechanisms to minimize risk impacts, which are compiled in six action protocols for infrastructures and water quality monitoring. As a novel contribution, the proposed methodology developed in the refugee camps incorporates besides the conventional water quality assessment concepts, the analysis of the volume of supplied water, linked with some water-washed diseases. Since the end of 2014, those protocols have begun to be applied obtaining results that have a positive effect on the life quality of refugees.

  9. THE MEDIEVAL AND OTTOMAN HAMMAMS OF ALGERIA; ELEMENTS FOR A HISTORICAL STUDY OF BATHS ARCHITECTURE IN NORTH AFRICA

    Directory of Open Access Journals (Sweden)

    Nabila Cherif-Seffadj

    2009-03-01

    Full Text Available Algerian medinas (Islamic cities have several traditional public baths (hammams. However, these hammams are the least known in the Maghreb countries. The first French archaeological surveys carried out on Islamic monuments and sites in Algeria, have found few historic baths in medieval towns. All along the highlands route, from Algiers (capital city of Algeria located in the North to Tlemcen (city in the Western part of Algeria, these structures are found in all the cities founded after the Islamic religion expanded in the Western North Africa. These buildings are often associated to large mosques. In architectural history, these baths illustrate original spatial and organizational compositions under form proportions, methods of construction, ornamental elements and the technical skills of their builders. The ancient traditions of bathing interpreted in this building type are an undeniable legacy. They are present through architectural typology and technical implementation reflecting the important architectural heritage of the great Roman cities in Algeria. Furthermore, these traditions and buildings evolved through different eras. Master builders, who left Andalusia to seek refuge in the Maghreb countries, added the construction and ornamentation skills and techniques brought from Muslim Spain, while the Ottomans contribution in the history of many urban cities is important. Hence, the dual appellation of the hammam as “Moorish bath” and “Turkish bath” in Algeria is the perfect illustration of the evolution of bath architecture in Algeria.

    The 2nd largest state in Africa, the Democratic and Popular Republic of Algeria is in the Northwest region of Africa along the Mediterranean. 91% of the population of 23 million are situated along the Mediterranean. The government of Algeria parallels the government of the United States in structure containing an executive, legislative and judicial branch and based on a constitution. The roles of the government are discussed as are political conditions and the founding history of the present government. Also discussed is the Algerian defense and foreign relations. The majority of Algerians are Muslim and of Arab, Berber or Arab-Berber stock. The Berbers are the indigenous people of Algeria. European influence, particularly French, is still prevalent however. Natural resources include oil, natural gas, iron ore and uranium, and the most prevalent industries are involved with the production and processing of these resources. While Algeria has made great inroads in the areas of health and education, it still faces a growing problem: housing. Conditions for travel, i.e. transportation, communication, and health, are favorable.

  11. Thermal performance prediction and sensitivity analysis for future deployment of molten salt cavity receiver solar power plants in Algeria

    Boudaoud, S.; Khellaf, A.; Mohammedi, K.; Behar, O.

    2015-01-01

    Highlights: • Performance of power plant with molten salt cavity receiver is assessed. • A method has been used to optimize the plant solar multiple, capacity factor and LEC. • Comparison of the simulated results to those of PS20 has shown good agreement. • Higher fossil fuel fraction reduces the LEC and increases the capacity factor. • Highland and Sahara regions are suitable for CRS plants deployment. - Abstract: Of all Concentrating Solar Power (CSP) technologies available today, the molten salt solar power plant appears to be the most important option for providing a major share of the clean and renewable electricity needed in the future. In the present paper, a technical and economic analysis for the implementation of a probable molten salt cavity receiver thermal power plant in Algeria has been carried out. In order to do so, we have investigated the effect of solar field size, storage capacity factor, solar radiation intensity, hybridization and power plant capacity on the thermal efficiency and electricity cost of the selected plant. The system advisor model has been used to perform the technical performance and the economic assessment for different locations (coastal, highland and Sahara regions) in Algeria. Taking into account various factors, a method has been applied to optimize the solar multiple and the capacity factor of the plant, to get a trade-off between the incremental investment costs of the heliostat field and the thermal energy storage. The analysis has shown that the use of higher fossil fuel fraction significantly reduces the levelized electricity cost (LEC) and sensibly increases the capacity factor (CF). The present study indicates that hybrid molten salt solar tower power technology is very promising. The CF and the LEC have been found to be respectively of the order of 71% and 0.35 $/kW e . For solar-only power plants, these parameters are respectively about 27% and 0.63 $/kW e . Therefore, hybrid central receiver systems are

    Full Text Available The hydrocarbon System Ourd Mya is located in the Sahara Basin. It is one of the producing basins in Algeria. The stratigraphic section consists of Paleozoic and Mesosoic, it is about 5000 m thick. In the eastern part, the basin is limited by the Hassi-Messaoud high zone which is a giant oil field produced from the Cambrian sands. The western part is limited by Hassi R`mel which is one of the biggest gas field in the world, it is produced from the triassic sands. The Mesozoic section lays on the lower Devonian and in the eastern part, on the Cambrian. The main source rock is Silurian shale with an average thickness of 50 m and a total organic matter of 6 % (14 % in some cases. Results of maturation modeling indicate that the lower Silurian source is in the oil window. The Ordovician shales are also a source rock but in a second order. Clastic reservoirs are in the Triassic sequence which is mainly fluvial deposit with complex alluvial channels, it is the main target in the basin. Clastic reservoirs within the lower Devonian section have a good hydrocarbon potential in the east of the basin through a southwest-northeast orientation. The late Triassic-Early Jurassic evaporites overlie the Triassic clastic interval and extend over the entire Oued Mya Basin. This is considered as a super-seal evaporate package, which consists predominantly of anhydrite and halite. For Paleozoic targets, a large number of potential seals exist within the stratigraphic column.This paper describe the main geological structure and mineral resources of Algeria.

    2009-04-01

    Full Text Available Sahrawi women are active agents in the social dynamics of the refugee camps, in which they have developeda number of coping strategies to overcome the hardships of a deteriorating humanitarian situation. Since the outbreak of the con#ict and the forced settlement in Tindouf, Algeria, women have been responsible for the entire management of refugee camps, assuming leadership roles in many sectors of society.This paper highlights the Sahrawi women’s contribution to the process of local human development in a context of protracted refuge such as the one in the Western Sahara. In addition to the enlargement of the refugee population’s capacities in relation to material and physical assets, social and organizational abilities, and motivational strengths, one of the major achievements of Sahrawi women has been their own individual and collective process of empowerment within the camp life.

  15. Environmental isotopes in the aquifers of the North Western Sahara

    International Nuclear Information System (INIS)

    Conrad, G.

    1975-09-01

    The isotopic composition of single rains at Beni-Abbes (Algeria) has been determined from 1964 to 1975. The weighed mean delta 18 O value is -3.54 %o vs. SMOW for all rains, -6.29 for rains higher than 10 mm. Only these more intense rains are believed to contribute significantly to groundwater recharge. Tritium content of precipitation varies from 900 TU in a 1964 rain, to 235 in 1967, 215 in 1968 and about 50 in 1972. The isotopic and chemical composition of water from a small salt lake nearby Beni-Abbes show variations depending on the evaporation rate and on the amount and origin of inflow. Groundwater in the Western Ground Erg contain significant amount of tritium, indicating recent recharge. The water is however submitted to evaporation as indicated by its 18 O and deuterium content. The so-called Continental Intercalaire aquifer, which extends over most of the Sahara desert, appears to be presently recharged in the outcropping areas like in Tidikelt, as shown by tritium and 14 C, and by the Western Ground Erg aquifer in the Gourara area, as shown by stable isotopes

  2. “Algeria vs Unemployment”: The Expatriation of Spaniards in Algeria as a Job Opportunity

    Directory of Open Access Journals (Sweden)

    María Jesús Cabezón Fernández

    2017-12-01

    Full Text Available High skilled transnational mobility between Spain and Algeria increased due to the intensification of the bilateral relationships, giving rise to a North-South mobility. The foreign enterprises set up in Algeria encouraged the high skilled mobilities as way to develop their professional careers in good labour conditions. Economic and social crisis provoked the intensification of the transnational mobility and emigration to Algeria, adding new actors like entrepreneurs and people unemployed who search for a job even in irregular condition. From a qualitative perspective, this paper focusses on analyse how the crisis reshaped the mobility of the Spanish expatriates, who changed privileges for precarisation, in a context perceived as adverse but necessary to avoid the unemployment in Spain.

  9. Review of wind energy use in Algeria

    International Nuclear Information System (INIS)

    Himri, Y.; Boudghene Stambouli, A.; Draoui, B.; Himri, S.

    2009-01-01

    Most scientists now agree that human-induced global climate change poses a serious threat to both society and the Earth's ecosystems. Renewable energy holds the key to future prosperity and a healthy global environment and is considered as a promising way to solve the problem of environmental pollution such as major environmental accidents, water pollution, maritime pollution, land use and sitting impact, radiation and radioactivity, solid waste disposal, hazardous air pollutants, ambient air quality (CO, CO 2 , SO x , NO x effluent gas emissions), acid rain, stratospheric ozone depletion, and global warming (GHG). Solar, wind and hydrogen power can be considered as potential renewable energy sources in Algeria. The share of renewable energy sources in Algeria primary energy supply is relatively low compared with European countries, though the trends of development are positive. One of the main strategic priorities of New Energy Algeria (NEAL) which is Algeria's renewable energy agency (government, Sonelgaz and Sonatrach), is striving to achieve a share of renewable energy sources in primary energy supply of 10-12% by 2010. IEA projects that the fastest growing sources of energy will be supplied by renewables. Much of this capacity will be installed in developing nations where solar and wind electric power is already competitive. Clearly, the nation that can capture a leadership position has potential for substantial economic returns. The article presents a review of the present wind energy situation and assessed potential of wind energy sources in Algeria in particular the southwest region of Algeria (Adrar, Timimoun and Tindouf).

    2012-01-01

    Background Households from vulnerable groups experiencing epidemiological transitions are known to be affected concomitantly by under-nutrition and obesity. Yet, it is unknown to what extent this double burden affects refugee populations dependent on food assistance. We assessed the double burden of malnutrition among Western Sahara refugees living in a protracted emergency. Methods and Findings We implemented a stratified nutrition survey in October–November 2010 in the four Western Sahara refugee camps in Algeria. We sampled 2,005 households, collecting anthropometric measurements (weight, height, and waist circumference) in 1,608 children (6–59 mo) and 1,781 women (15–49 y). We estimated the prevalence of global acute malnutrition (GAM), stunting, underweight, and overweight in children; and stunting, underweight, overweight, and central obesity in women. To assess the burden of malnutrition within households, households were first classified according to the presence of each type of malnutrition. Households were then classified as undernourished, overweight, or affected by the double burden if they presented members with under-nutrition, overweight, or both, respectively. The prevalence of GAM in children was 9.1%, 29.1% were stunted, 18.6% were underweight, and 2.4% were overweight; among the women, 14.8% were stunted, 53.7% were overweight or obese, and 71.4% had central obesity. Central obesity (47.2%) and overweight (38.8%) in women affected a higher proportion of households than did GAM (7.0%), stunting (19.5%), or underweight (13.3%) in children. Overall, households classified as overweight (31.5%) were most common, followed by undernourished (25.8%), and then double burden–affected (24.7%). Conclusions The double burden of obesity and under-nutrition is highly prevalent in households among Western Sahara refugees. The results highlight the need to focus more attention on non-communicable diseases in this population and balance obesity prevention

    2012-12-01

    Algeria aspires to protect its water resources and to provide a sustainable answer to water supply and management issues by carrying out a national water plan. This program is in line with all projects the Algerian Government is implementing to improve its water sector performance. The water strategy focuses on desalination for the coastal cities, medium-sized dams to irrigate the inland mountains and high plateau, and ambitious water transfer projects interconnecting Algeria\\'s 65 dams to bring water to water scarce parts of the country. Waste water treatment and water reclamation technologies are also highly sought after. The main objective of the country\\'s water policy consists on providing sufficient potable water for the population supply. This objective is undertaken by increasing the water resources and availability. © 2012 Desalination Publications. All rights reserved.

    Dalila Kherchouche2, Kevin J. Anchukaitis3, Bachir Oudjehih2, Hayat Touchan4, Said Slimani5, and David M. Meko1Drought is one of the main natural factors in declining tree-ring growth and the production of agricultural crops in Algeria. Here we will address the variability of growing conditions for wheat in Algeria with climatic data and a tree-ring reconstruction of January-June precipitation from ten Pinus halepensis tree-ring chronologies. A regression-based reconstruction equation explains up to 74% of the variance of precipitation in the 1970-2011 calibration period and cross validates well. Classification of dry years by the 30% percentile of observed precipitation (131 mm) yields a maximum length of drought of five years (1877-1881) and increasing frequency of dry years in the late 20th and early 21stcenturies. A correlation-based sensitivity analysis shows a similar pattern of dependence of tree-growth and wheat production on monthly and seasonal precipitation, but contrasting patterns of dependence on temperature. The patterns are interpreted by reference to phenology, growth phases, and - for wheat agricultural practices. We apply these interpretations to understand possible impacts of climate variability on the agricultural productivity of past civilizations in the Mediterranean. 2Institute of Veterinary and Agronomy Sciences, The University Hadj-Lakhdar, Batna 05000, Algeria, d.kherchouche@yahoo.fr and oudjehihbachir@yahoo.fr3University of Arizona, ENR2 Building, 1064 E Lowell Street, PO Box 210137, Tucson, AZ 85721-0137, kanchukaitis@email.arizona.edu4Faculty of Agriculture, University of Aleppo, Aleppo-Syria, dr.htouchan@gmail.com5Faculty of Biological Sciences and Agronomy, The University Mouloud Mammeri, Tizi Ouzou 15000, Algeria, slimanisaid@yahoo.fr1Laboratory of Tree Ring Research, The University of Arizona, 1215 E.

  5. Fuel gases in Algeria

    International Nuclear Information System (INIS)

    Arachiche, B.; Elandaloussi, H.

    1996-01-01

    For a country like Algeria, fuel gases represent an important economical challenge. To answer the increasing energy demand in the transportation sector, the use of fuel gases allows to preserve the petroleum reserves and to create specific industrial structures devoted to LPG-f (liquefied petroleum gas-fuel) and NGV (natural gas for vehicles). This paper presents the energy policy of Algeria, its reserves, production, and exportations of hydrocarbons and the internal rational use of energy sources according to its economic and environmental policy and to its internal needs. The energy consumption of Algeria in the transportation sector represents 2/3 of the petroleum products consumed in the internal market and follows a rapid increase necessary to the socio-economic development of the country. The Algerian experience in fuel gases is analysed according to the results of two successive experimentation periods for the development of NGV before and after 1994, and the resulting transportation and distribution network is described. The development of LPG-f has followed also an experimental phase for the preparation of regulation texts and a first statement of the vehicles conversion to LPG-f is drawn with its perspectives of development according to future market and prices evolutions.

    2018-05-01

    In the Souf of Algeria, the roofs of all constructions are arranged like corbelled domes, built with local particular material to this region, which is the desert rose. These cupolas describe a unique landscape of historic centres. Such constructions include a widespread and precious heritage that deserves protection to save this urban landscape which constitutes an element of identity of heritage built upon the material as well as the immaterial of the local know-how. Unfortunately, these architectural elements have undergone alterations that devalue the urban landscape and destabilize the buildings. However, the structural system that provides stability and endurance to this day remains an open question. In this, paper, we describe the role of desert rose cupolas in the construction of a single urban landscape and we contribute to this knowledge. Then, we explain the role of the availability of the materials locals (desert rose and tafza) to appearance ad emergence of construction with cupolas typology. In addition, we describe these materials locals, and the method to them usage. In the end, we have traced the process of construction of these cupolas by corbelling which is mounted by successive courses of the desert rose and the plaster mortar.

    Full Text Available Soil erosion by rain and surface runoff is an important problem in the Mediterranean countries. The study of the relationship between erosion and sediment transport with hydrological and climatic factors have b een conducted in many countries around the world. The aim of this work is to show ra infall impact on the variability of spatial and temporal concentration in twelve drainage basins in the west of Algeria. We will also seek to find a representative parameter of rainfall erosive potential on a Time and spatial scale. When studying sediment transport in twelve drainage basins of the Centre and the west of Algeria, we have found that the modified Fournier index Which explains much of the specific degradation comp ared to the Fournier index. The study of the temporal variability of the annual rain fall series, modified Fournier index and concentration of the precipitation in the year for a series from 1930 to 2007 showed a negative trend of the two variables. The a nnual rainfall and modified Fournier index have declined by more than 20%. This de cline is more significant in inland areas.

  12. Paleohydrology and paleoenvironments at Bir Sahara: Pleistocene lithostratigraphy and sedimentology in the southern Egyptian Sahara

    Science.gov (United States)

    Hill, Christopher L.; Schild, Romuald

    2017-12-01

    The Bir Sahara area contains a remarkable record of Middle and Late Pleistocene hydrologic and environmental conditions for Saharan North Africa, based on lithostratigraphic and sedimentologic evidence from basin-fill deposits. Some of the deposits contain Lower Paleolithic (Acheulean) or Middle Paleolithic artifacts that help to constrain their age, since Acheulian artifacts are assigned to the Middle Pleistocene, while Middle Paleolithic artifacts are limited to either the Middle or Late Pleistocene. Locality BS-14 is in the southern part of Bir Sahara, while localities E-88-15, E-88-2, BS-13, and BS-16 are situated in the south-central part of the deflational basin, closer to the present-day water-hole. Lowered groundwater conditions during arid intervals resulted in erosional topographic basins. These deflational basins were later filled with sediments associated with wetter hydrologic conditions. The oldest studied sedimentary sequence in the Bir Sahara depression (BS-14) contains in situ Acheulian artifacts. Acheulian handaxes are found in sands underlying carbonates that are interpreted as evidence of spring-fed pond and marsh environments during a Middle Pleistocene wet interval. At the E-88-15 locality, the stratigraphic sequence documents deposition in a possible perennial pond or small lake that varied in extent and depth and is associated with Middle Paleolithic artifacts. At E-88-12 and BS-13, lateral and vertical variations in the lithofacies of the basin-fill sediments provide additional records of changing hydrologic conditions during the Late Pleistocene. These hydrologic conditions appear to reflect variations in water-table levels related to groundwater recharge and, at times, local rains.

  14. Typological thinking: Then and now.

    Science.gov (United States)

    Witteveen, Joeri

    2018-05-01

    A popular narrative about the history of modern biology has it that Ernst Mayr introduced the distinction between "typological thinking" and "population thinking" to mark a contrast between a metaphysically problematic and a promising foundation for (evolutionary) biology, respectively. This narrative sometimes continues with the observation that, since the late-20th century, typological concepts have been making a comeback in biology, primarily in the context of evolutionary developmental biology. It is hard to square this narrative with the historical and philosophical literature on the typology/population distinction from the last decade or so. The conclusion that emerges from this literature is that the very distinction between typological thinking and population thinking is a piece of mere rhetoric that was concocted and rehearsed for purely strategic, programmatic reasons. If this is right, it becomes hard to make sense of recent criticisms (and sometimes: espousals) of the purportedly typological underpinnings of certain contemporary research programs. In this article, I offer a way out of this apparent conflict. I show that we can make historical and philosophical sense of the continued accusations of typological thinking by looking beyond Mayr, to his contemporary and colleague George Gaylord Simpson. I show that before Mayr discussed the typology/population distinction as an issue in scientific metaphysics, Simpson introduced it to mark several contrasts in methodology and scientific practice. I argue that Simpson's insightful discussion offers useful resources for classifying and assessing contemporary attributions of typological thinking. © 2018 The Authors.

  16. Algeria: the illusions of oil wealth - CERI Studies No. 168

    International Nuclear Information System (INIS)

    Martinez, Luis

    2010-09-01

    Thirty years after the nationalisation of hydrocarbons Algeria's oil wealth seems to have disappeared judging by its absence in the country's indicators of well-being. In Algeria oil led to happiness for a few and sadness for many. The absence of controls over oil revenue led to the industries downfall. Since 2002 Algeria is again seeing oil wealth. The increase in the price per barrel from 30 to 147 dollars between 2002 and 2008 provided the country with unexpected revenue permitting it to accumulate funds estimated, in 2009, at 150 billion dollars. Abdelaziz Bouteflika, returned to a devastated Algeria to restore civil order, unexpectedly benefited from this price increase. Thus, in addition to national reconciliation he was able to offer Algeria renewed economic growth. However, given that the wounds of the 1990's are not entirely healed and the illusions of oil wealth have evaporated this unexpected return of financial abundance raises concerns. To what ends will this manna be put? Who will control it? Will it provoke new violence and conflict? (author)

  18. Atmospheric feedbacks in North Africa from an irrigated, afforested Sahara

    Science.gov (United States)

    Kemena, Tronje Peer; Matthes, Katja; Martin, Thomas; Wahl, Sebastian; Oschlies, Andreas

    2018-06-01

    Afforestation of the Sahara has been proposed as a climate engineering method to sequester a substantial amount of carbon dioxide, potentially effective to mitigate climate change. Earlier studies predicted changes in the atmospheric circulation system. These atmospheric feedbacks raise questions about the self-sustainability of such an intervention, but have not been investigated in detail. Here, we investigate changes in precipitation and circulation in response to Saharan large-scale afforestation and irrigation with NCAR's CESM-WACCM Earth system model. Our model results show a Saharan temperature reduction by 6 K and weak precipitation enhancement by 267 mm/year over the Sahara. Only 26% of the evapotranspirated water re-precipitates over the Saharan Desert, considerably large amounts are advected southward to the Sahel zone and enhance the West African monsoon (WAM). Different processes cause circulation and precipitation changes over North Africa. The increase in atmospheric moisture leads to radiative cooling above the Sahara and increased high-level cloud coverage as well as atmospheric warming above the Sahel zone. Both lead to a circulation anomaly with descending air over the Sahara and ascending air over the Sahel zone. Together with changes in the meridional temperature gradient, this results in a southward shift of the inner-tropical front. The strengthening of the Tropical easterly jet and the northward displacement of the African easterly jet is associated with a northward displacement and strengthening of the WAM precipitation. Our results suggest complex atmospheric circulation feedbacks, which reduce the precipitation potential over an afforested Sahara and enhance WAM precipitation.

    Full Text Available Objective: To evaluate the influence of the temperature on honey colour, polyphenol contents and antimycotic capacity and to evaluate the correlation between these parameters. Methods: Sahara honey were heated up to 25, 50, 75 and 100 °C for 15, 30 and 60 min, and their colour intensity, polyphenol contents and antimycotic capacity. The Folin-Ciocalteu test was used to determine the total polyphenol contents (TPC. The antimycotic activity was evaluated both by agar diffusion method and micro wells dilution method against the Candida albicans (C. albicans and Candida glabrata (C. glabrata. Results: Initial values for TPC in Sahara honey ranged from 0.55 to 1.14 mg of gallic acid per kg of honey, with the average value of 0.78 mg of gallic acid per kg of honey. The TPC values after heat-treatment were 0.54 to 1.54 with the average value of 1.49 mg. The minimal inhibitory concentrations before heat-treatment of Sahara honey against C. albicans and C. glabrata ranged from 3.06%-12.5% and 50% respectively. After heat-treatment the minimal inhibitory concentrations between 12.5% and 50% for C. albicans and C. glabrata, respectively. The diameters of inhibition zones of Sahara honey with 50% concentration varied from (12.67-15.00 mm by C. albicans to (14.33-15.67 mm by C. glabrata. The diameters of inhibition zones after heat-treatment at 25 and 50 °C for 15.30 and 60 min ranged from (2.00-18.67 mm by C. albicans to (8.00-16.67 mm by C. glabrata. Statistically significant relations between the TPC and the colour intensity of Sahara honey (r=0.99, P<0.05. Furthermore, the results showed that the TPC and colour is not correlated with the antimycotic capacity. Conclusions: To our knowledge this is the first report on the antimycotic capacity of Sahara honey.

  5. (InEdible Algeria: Transmitting Pied-Noir Nostalgia Through Food

    Directory of Open Access Journals (Sweden)

    Amy L. Hubbell

    2013-07-01

    Full Text Available For those exiled from Algeria during and after the Algerian War for Independence (1954-1962, sustaining memories of the homeland has been a consuming pastime. Food has especially played a large part in reconnecting Algeria’s former French citizens, the Pieds-Noirs, to their past. Annual gatherings feature typical dishes such as couscous, merguez, méchoui, mouna, which like the Proustian madeleine, transport the Pieds-Noirs to a preceding time of wholeness and comfort, allowing them to experience, if only fleetingly, a sense of immortality. While food has a reparative quality for the community’s memory, it is also the site of rejection and pain for some. Marie Cardinal writes about food as a site of unity with the indigenous Algerian community and rejection from her colonial French family. Similarly, in the collective autobiography Quatre soeurs: Hier, en Algérie, aujourd’hui en France, Frédérique Boblin, Eve Calo, Nelly Collet and Fabienne Rozotte explain their shared eating disorders as tied to their expulsion from Algeria. This essay demonstrates that the Pieds-Noirs can eat to remember Algeria, but the Algeria they knew can also prove to be inedible.

  6. Economic development, mobility and traffic accidents in Algeria.

    The aim of this contribution is to estimate the impact of road economic conditions and mobility on traffic accidents for the case of Algeria. Using the cointegration approach and vector error correction model (VECM), we will examine simultaneously short term and long-term impacts between the number of traffic accidents, fuel consumption and gross domestic product (GDP) per capital, over the period 1970-2013. The main results of the estimation show that the number of traffic accidents in Algeria is positively influenced by the GDP per capita in the short and long term. It implies that a higher economic development worsens the road safety situation. However, the new traffic rules adopted in 2009 have an impact on the forecast trend of traffic accidents, meaning efficient public policy could improve the situation. This result calls for a strong political commitment with effective countermeasures for avoiding the further deterioration of road safety record in Algeria. Copyright © 2016 Elsevier Ltd.

    2012-01-01

    In this paper there are discussed the possibilities of using solar energy to power supply of electron accelerators that can be used to solve environmental problems, such as sewage treatment and radiation sterilization. Algeria, due to geographical location, has one of the largest 'solar deposits' around the world. Insolation time exceeds 2,000 hours per year and may reach up to 3,900 hours per year on the High Plains and the Sahara. Daily energy that falls on a horizontal surface one square meter is about 5 KWh on the most territory of Algeria, i.e. approximately 1,700 kWh per m 2 per year in the North and 2,263 kWh per m 2 per year in the south. Independent energy sources from the Sun can also bring economic development of the Sahara region.

    Deserts and arid regions are generally perceived as bare and rather homogeneous areas of low diversity. The Sahara is the largest warm desert in the world and together with the arid Sahel displays high topographical and climatic heterogeneity, and has experienced recent and strong climatic oscillations that have greatly shifted biodiversity distribution and community composition. The large size, remoteness and long-term political instability of the Sahara-Sahel, have limited knowledge on its biodiversity. However, over the last decade, there have been an increasing number of published scientific studies based on modern geomatic and molecular tools, and broad sampling of taxa of these regions. This review tracks trends in knowledge about biodiversity patterns, processes and threats across the Sahara-Sahel, and anticipates needs for biodiversity research and conservation. Recent studies are changing completely the perception of regional biodiversity patterns. Instead of relatively low species diversity with distribution covering most of the region, studies now suggest a high rate of endemism and larger number of species, with much narrower and fragmented ranges, frequently limited to micro-hotspots of biodiversity. Molecular-based studies are also unravelling cryptic diversity associated with mountains, which together with recent distribution atlases, allows identifying integrative biogeographic patterns in biodiversity distribution. Mapping of multivariate environmental variation (at 1 km × 1 km resolution) of the region illustrates main biogeographical features of the Sahara-Sahel and supports recently hypothesised dispersal corridors and refugia. Micro-scale water-features present mostly in mountains have been associated with local biodiversity hotspots. However, the distribution of available data on vertebrates highlights current knowledge gaps that still apply to a large proportion of the Sahara-Sahel. Current research is providing insights into key

  13. Refraining from terror: the puzzle of non violence in Western Sahara

    Directory of Open Access Journals (Sweden)

    Matthew Porges

    2018-02-01

    Full Text Available In Western Sahara, the former Spanish colony occupied by Morocco since 1975, virtually no violent resistance has been mounted by the indigenous Sahrawi people since the end of the 1975-1991 war between Morocco and the pro-independence Polisario Front. This absence of violence is puzzling in the light of several factors: the widespread public support for independence; the social and economic disparities between Moroccan and Sahrawi inhabitants of the territory; and Morocco’s brutal repression of Sahrawi culture, resistance, and expressions of proindependence feeling. This article examines the logic of violence (and its absence and of resistance, and draws lessons from Western Sahara. As well as advancing theoretical development, the article makes a methodological contribution to the study of resistance, and improves our understanding of the Western Sahara conflict through fieldwork, including around 60 interviews with Sahrawi activists conducted in the summer of 2014.

    Full Text Available This article describes process segmentation typology during business process management implementation in Czech companies. Process typology is important for a manager’s overview of process orientation as well as for a manager’s general understanding of business process management. This article provides insight into a process-oriented organizational structure. The first part analyzes process segmentation typology itself as well as some original results of quantitative research evaluating process segmentation typology in the specific context of Czech company strategies. Widespread data collection was carried out in 2006 and 2013. The analysis of this data showed that managers have more options regarding process segmentation and its selection. In terms of practicality and ease of use, the most frequently used method of process segmentation (managerial, main, and supportive stems directly from the requirements of ISO 9001. Because of ISO 9001:2015, managers must now apply risk planning in relation to the selection of processes that are subjected to process management activities. It is for this fundamental reason that this article focuses on process segmentation typology.

    2011-12-01

    Full Text Available While there is little doubt that Algeria was of enormous importance to the theoretical output that is often recognized as French, here I would like to ask: what is at stake in re-inscribing these French intellectuals as postcolonial? In what ways did the particularities of Algerian history impact French philosophy? Indeed, if the term postcolonial is meant to describe those who were influenced by events in Algeria, then an entire generation of French thinkers might be considered postcolonial to varying degrees. Surely Derrida’s oeuvre was influenced by his experiences in Algeria, but does this make him postcolonial in the same way as Jean-Paul Sartre or Pierre Bourideu, who have also become important figures in postcolonial theory?

    Typology of incarcerated intimate partner aggressors. People who engage in intimate partner violence do not constitute a homogeneous group. Many studies in the Anglo-Saxon countries back the possibility of differentiating several subtypes of aggressors, but there are differences among them. One of the main applications of these typologies is the adaptation of the treatments to the subjects' characteristics. The aim of the present pilot study was to empirically establish a typology of batterers in Spain. The sample of 50 convicted violent intimate partner offenders was obtained from the Brians-2 penitentiary (Barcelona). Self-esteem, anger, cognitive distortions, and personality disorders were evaluated, as well as the frequency and type of violence. The results suggest the existence of two subtypes, distinguishable on the basis of the predictive dimensions, and so, partially confirm the typological proposals.

  17. Lakeside cemeteries in the Sahara: 5000 years of holocene population and environmental change.

    Directory of Open Access Journals (Sweden)

    Paul C Sereno

    Full Text Available BACKGROUND: Approximately two hundred human burials were discovered on the edge of a paleolake in Niger that provide a uniquely preserved record of human occupation in the Sahara during the Holocene ( approximately 8000 B.C.E. to the present. Called Gobero, this suite of closely spaced sites chronicles the rapid pace of biosocial change in the southern Sahara in response to severe climatic fluctuation. METHODOLOGY/PRINCIPAL FINDINGS: Two main occupational phases are identified that correspond with humid intervals in the early and mid-Holocene, based on 78 direct AMS radiocarbon dates on human remains, fauna and artifacts, as well as 9 OSL dates on paleodune sand. The older occupants have craniofacial dimensions that demonstrate similarities with mid-Holocene occupants of the southern Sahara and Late Pleistocene to early Holocene inhabitants of the Maghreb. Their hyperflexed burials compose the earliest cemetery in the Sahara dating to approximately 7500 B.C.E. These early occupants abandon the area under arid conditions and, when humid conditions return approximately 4600 B.C.E., are replaced by a more gracile people with elaborated grave goods including animal bone and ivory ornaments. CONCLUSIONS/SIGNIFICANCE: The principal significance of Gobero lies in its extraordinary human, faunal, and archaeological record, from which we conclude the following: The early Holocene occupants at Gobero (7700-6200 B.C.E. were largely sedentary hunter-fisher-gatherers with lakeside funerary sites that include the earliest recorded cemetery in the Sahara.Principal components analysis of craniometric variables closely allies the early Holocene occupants at Gobero with a skeletally robust, trans-Saharan assemblage of Late Pleistocene to mid-Holocene human populations from the Maghreb and southern Sahara.Gobero was abandoned during a period of severe aridification possibly as long as one millennium (6200-5200 B.C.E.More gracile humans arrived in the mid

    2014-01-01

    Full Text Available The history of scientific development in Algeria, which has not been long, represents a series of continual rises and falls. The Algerian leadership and researchers have been making efforts to create Algeria's national science through protection from the western scientific tradition, which is reminiscent of the colonial period of the country, and at the same time adoption of scientific knowledge and scientific institutions functioning principles from abroad, with no organizational or scientific experience of their own. Since the time the independent Algerian state was established, its scientific development has been inevitably coupled with active support of European countries, especially France, and other western and non-western states. Today the Algerian leadership is highly devoted to the modernization of the national scientific and research potential in strong cooperation with its foreign partners. The article concentrates on examining the present period (the 2000s of the scientific development in Algeria. The main conclusion is that there still is a number of problems - for Algeria until now lacks an integral scientific community with the state preserving its dominating role in science and research activities. Despite these difficulties, the Algerian science has made an outstanding progress. The efficiently built organizational scientific structure, the growing science and technology cooperation with foreign countries as well as the increasing state expenses in science allow to hope for further success of the Algerian scientific development.

  3. Promotion of renewable energies in Algeria: Strategies and perspectives

    International Nuclear Information System (INIS)

    Stambouli, Amine Boudghene

    2011-01-01

    During the last few years, political support for renewable energies has been growing continuously both at the national and international level and most scientists now agree that the Middle East and North Africa (MENA) are perfectly placed to play a leading role in the lucrative future solar and wind power industries. The interest for the development of renewable energies was perceived very early in Algeria with the creation of the solar energy institute as soon as 1962. Algeria plays a very important role in world energy markets, both as a significant hydrocarbons producer and exporter, as well as a key participant in the renewable energy market. Due to its geographical location, Algeria holds one of the highest solar reservoirs in the world. This paper deals with a review of the present renewable energy (RE) situation and assessed present and future potential of RE sources in Algeria. It also discusses the trends and expectation in solar and wind systems applications and the aspects of future implementation of renewable energies making emphasis on the Middle East and North Africa (MENA) region status. The problem related to the use of RES and polices to enhance the use of these sources are also analysed in this paper. In addition the available capacity building, the technical know-how for each RE sources technology and localising manufacturing of RE equipments have been defined. (author)

    2016-06-01

    Full Text Available In the framework of the Fennec international programme, a field campaign was conducted in June 2011 over the western Sahara. It led to the first observational data set ever obtained that documents the dynamics, thermodynamics and composition of the Saharan atmospheric boundary layer (SABL under the influence of the heat low. In support to the aircraft operation, four dust forecasts were run daily at low and high resolutions with convection-parameterizing and convection-permitting models, respectively. The unique airborne and ground-based data sets allowed the first ever intercomparison of dust forecasts over the western Sahara. At monthly scale, large aerosol optical depths (AODs were forecast over the Sahara, a feature observed by satellite retrievals but with different magnitudes. The AOD intensity was correctly predicted by the high-resolution models, while it was underestimated by the low-resolution models. This was partly because of the generation of strong near-surface wind associated with thunderstorm-related density currents that could only be reproduced by models representing convection explicitly. Such models yield emissions mainly in the afternoon that dominate the total emission over the western fringes of the Adrar des Iforas and the Aïr Mountains in the high-resolution forecasts. Over the western Sahara, where the harmattan contributes up to 80 % of dust emission, all the models were successful in forecasting the deep well-mixed SABL. Some of them, however, missed the large near-surface dust concentration generated by density currents and low-level winds. This feature, observed repeatedly by the airborne lidar, was partly forecast by one high-resolution model only.

  7. Sahara Coal: the fine art of collecting fines for profit

    Energy Technology Data Exchange (ETDEWEB)

    Schreckengost, D.; Arnold, D.

    1984-09-01

    Because of a change in underground mining methods that caused a considerable increase in the amount of fine sizes in the raw coal, Sahara Coal Co. designed and constructed a unique and simple fine coal system at their Harrisburg, IL prep plant. Before the new system was built, the overload of the fine coal circuit created a cost crunch due to loss of salable coal to slurry ponds, slurry pond cleaning costs, and operating and maintenance costs--each and every one excessive. Motivated by these problems, Sahara designed a prototype system to dewater the minus 28 mesh refuse. The success of the idea permitted fine refuse to be loaded onto the coarse refuse belt. Sahara also realized a large reduction in pond cleaning costs. After a period of testing, an expanded version of the refuse system was installed to dewater and dry the 28 mesh X 0 clean coal. Clean coal output increased about 30 tph. Cost savings justified the expenditures for the refuse and clean coal systems. These benefits, combined with increased coal sales revenue, paid back the project costs in less than a year.

    Argasid ticks include vectors of relapsing fevers caused by Borrelia spp. in humans, and they can transmit arboviruses and other bacterial pathogens. Knowledge about soft ticks ( Ixodida: Argasidae ) in Algeria is incomplete, and distribution data need to be updated. Here we report a series of entomologic investigations that we conducted in five different areas in Algeria between 2012 and 2015. Ticks were identified by entomologic keys and molecular tools (16S rRNA gene). Six distinct species belonging to two genera were identified, including Ornithodoros capensis s.s., Ornithodoros rupestris, Ornithodoros occidentalis, Ornithodoros erraticus, Ornithodoros sonrai and Argas persicus. The present study highlights the distribution of soft ticks, the establishment of an update inventory with nine species and associated pathogens detected in argasid ticks in Algeria.

    The purpose of this study is to review the causal link in the Granger sense, between energy consumption and economic growth in Algeria, to determine its implications for economic policy. The analysis was done based on Granger static and causality tests using statistical data on per capita primary energy consumption and gross domestic product per inhabitant in Algeria, over the 1965-2008 period. The results of the survey show that there is, in Algeria, a strong link between energy consumption per inhabitant and GDP per inhabitant. The results also suggest the lack of a long term impetus (no co-integration) between energy consumption and economic growth. In addition, there is a one-way causal link between GDP and energy consumption, i.e. the prior GDP data provides a better forecast of energy consumption level, but not the contrary. In other words, GDP explains consumption, not the contrary. (author)

    2011-01-01

    In creolist circles, there has been a long-standing debate whether creoles differ structurally from non-creole languages and thus would form a special class of languages with specific typological properties. This debate about the typological status of creole languages has severely suffered from...... a lack of systematic empirical study. This paper presents for the first time a number of large-scale empirical investigations of the status of creole languages as a typological class on the basis of different and well-balanced samples of creole and non-creole languages. Using statistical modeling...... (multiple regression) and recently developed computational tools of quantitative typology (phylogenetic trees and networks), this paper provides robust evidence that creoles indeed form a structurally distinguishable subgroup within the world’s languages. The findings thus seriously challenge approaches...

  17. Energy and nuclear power planning study for Algeria

    International Nuclear Information System (INIS)

    1985-01-01

    This study, conducted jointly by a team of engineers and economists from the Sonelgaz company and the IAEA, had three objectives: (1) To perform a preliminary economic study aimed at initiating thinking on the role that nuclear power could play in Algeria's long-term energy structure and to suggest reasonable hypotheses on what share of the energy market nuclear power might supply. (2) To train a team of Algerian engineers and economists in long-term economic planning techniques. Once the team has gained a basic knowledge through this preliminary study, it will be in a position to continue the process, to perform other, more detailed independent analyses and to review the entire process should economic conditions change. (3) To introduce in Algeria the computer techniques and facilities needed to carry out such energy investment planning studies for electricity production. The main aim throughout the studies was to train a team of Algerian engineers in energy planning rather than to come to definitive conclusions on the problem of introducing nuclear power in Algeria. Two successive analyses were performed. The first consisted in evaluating the final energy requirements which will result in the medium and long term (by 2015) from the implementation of the economic development policies in the Five Year Plan (up to 1984) and in the proposals for the next decade (up to 1990) being studied by the Algerian Ministry of Planning. The second part is concerned only with the results regarding future electricity requirements, which are used as input data in studying the optimization of Algeria's future electricity generating system. Various methods of generation are analysed and included in an econometric model in order to make a sequential determination of the most economic composition of power generating capacity

    Full Text Available The transitivizing/detransitivizing typology of Nichols et al. 2004 also proves useful to historical linguistics. We focus on language families of northern Eurasia, chiefly the three oldest families (Indo-European, Uralic, Nakh-Daghestanian, some of their daughter branches aged about 2000-3000 years, and one younger family for which we have data on enough daughters to support a family phylogeny (Tungusic. We use the 18-pair wordlist of Nichols et al. 2004, which typologizes each pair of verbs depending on which of the two is derived. We make some improvements in the coding of grammatical properties and the typologization of pairs. NeighborNet trees based on this information reveal family-wide linguistic geography and areal trends. Adding minimal information about the cognacy or non-cognacy of the roots of the wordlist items produces Neighbor- Net trees which approximate well the known phylogeny of the family. Thus very small closed data sets, collected originally for typology, yield rich information about language family history - strikingly, a mere 18 verbs (9 pairs, coded for morphological type and cognacy, yield a very good genealogical tree - while historical methods have also improved the typology.

  3. Energy Consumption and Economic Growth in Algeria: Cointegration and Causality Analysis

    Directory of Open Access Journals (Sweden)

    Cherfi Souhila

    2012-01-01

    Full Text Available This study investigates the energy consumption-growth nexus in Algeria. The causal relationship between the logarithm of per capita energy consumption (LPCEC and the logarithm of per capita GDP (LPCGDP during the 1965-2008 period is examined using the threshold cointegration and Granger causality tests. The estimation results indicate that the LPCEC and LPCGDP for Algeria are non cointegrated and that there is a uni-directional causality running from LPCGDP to LPCEC, but not vice versa. The research results strongly support the neoclassical perspective that energy consumption is not a limiting factor to economic growth in Algeria. Accordingly, an important policy implication resulting from this analysis is that government can pursue the conservation energy policies that aim at curtailing energy use for environmental friendly development purposes without creating severe effects on economic growth. The energy should be efficiently allocated into more productive sectors of the economy.

    Full Text Available The architecture of traditional historic cities in Algeria has specific spatial and constructive characteristics despite the influence of the Andalusian-Ottoman style. In the case of Cherchell (a historic city 100kms west of Algiers, the architectural elements interpret these architectural references. These elements exist in a complex archaeological, historic and cultural fabric based on architectural and urban analogies, reminders and references. The paper focuses on the typological study of the historic hammāms of Cherchell. It is aimed to analyse the diverse correlations between specific urban amenities and the residential fabric framed within the spatial organization, proportional modulation and structural modes. In this paper, the spatial organisation of the public baths of Cherchell is identified. It is a nodal spiral organization developed around the hot room. It follows the Ottoman spatial prototype of Algiers hammāms. However, the specific characteristic of Cherchell baths is in their constructive system for the roofing covering the central space of the hot room. The roofing consists of an octagonal dome, where the transition to the large square of the hot room is covered by trusses supporting tiled roofing, inspired by the domestic Cherchell architecture of that era.

    Urban mobility is a pressing problem and one growing with urbanization. Urban mobility, for example, accounts for 28 % of all CO2 emissions from road transport and restrictions in urban mobility have economic and social consequences. Occupational flow, movement to and from work, plays a vital role in shaping urban mobility patterns and is dependent on urban infrastructures as well as the geographical distribution of households and occupations. Urban mobility varies among different population subgroups such as race, age, and income in complex multivariate patterns. To explore and quantify these patterns, we use multivariate clustering to build a typology of urban mobility for the Metropolitan Statistical Areas of the United States using the occupational flow data from US Census Bureau's Longitudinal Employer-Household Dynamics- Origin-Destination Employment Statistics. We use characteristics such as work radius, connectivity, and number of jobs for different population subgroups such as income, age, and industry to define the typology, objectively classifying metropolitan areas with similar mobility patterns as belonging to the same mobility type. The mobility typology addresses whether urban areas with similar transportation infrastructure have similar mobility patterns. Additionally, similarities and differences in the mobility typology of the demographic groups provides valuable insights into overall mobility experience which can help transportation planners design equitable and sustainable transportation infrastructures.

    2014-11-01

    During a National Science Foundation (US) funded "International Greening of Cities Workshop" in Auckland, New Zealand, participants agreed an effective urban green infrastructure (GI) typology should identify cities' present stage of GI development and map next steps to mainstream GI as a component of urban infrastructure. Our review reveals current GI typologies do not systematically identify such opportunities. We address this knowledge gap by developing a new typology incorporating political, economic, and ecological forces shaping GI implementation. Applying this information allows symmetrical, place-based exploration of the social and ecological elements driving a city's GI systems. We use this information to distinguish current levels of GI development and clarify intervention opportunities to advance GI into the mainstream of metropolitan infrastructure. We employ three case studies (San Antonio, Texas; Auckland, New Zealand; and New York, New York) to test and refine our typology.

    Archaeology can provide insight into interactions of climate change and human activities in sensitive areas such as the Sahara, to the benefit of both disciplines. Such analyses can help set bounds on climate change projections, perhaps identify elements of tipping points, and provide constraints on models. The opportunity exists to more precisely constrain the relationship of natural solar and climate interactions, improving understanding of present and future anthropogenic forcing. We are beginning to explore the relationship of human occupation of the Sahara and long-term solar irradiance variations synergetic with changes in atmospheric-ocean circulation patterns. Archaeological and climate records for the last 12 K years are gaining adequate precision to make such comparisons possible. We employ a range of climate records taken over the globe (e.g. Antarctica, Greenland, Cariaco Basin, West African Ocean cores, records from caves) to identify the timing and spatial patterns affecting Saharan climate to compare with archaeological records. We see correlation in changing ocean temperature patterns approx. contemporaneous with drying of the Sahara approx. 6K years BP. The role of radar images and other remote sensing in this work includes providing a geographically comprehensive geomorphic overview of this key area. Such coverage is becoming available from the Japanese PALSAR radar system, which can guide field work to collect archaeological and climatic data to further constrain the climate change chronology and link to models. Our initial remote sensing efforts concentrate on the Gilf Kebir area of Egypt.

    Full Text Available The typology of buyers and buying actions contracts are specific categories of consumer behaviour, determining group buyers and buying actions in classes, to fragment the markets. Market fragmentation through buyer typoligy and/or segmentation is presently characterized by a multitude of theoretical approaches and are especially generated by the common practice in the respective business. These two concepts are used for the same purpose, the essential difference being their starting point: the segmentation fragments the markets as a whole, while the typology of the buyer and of buying actions generate classifications starting from individual cases.

    In order to investigate the prevalence of rickettsioses in febrile exanthemas in eastern Algeria, we conducted a prospective serological analysis of all patients presenting with this clinical picture at the Infectious Diseases Department in the Batna Hospital from January 2000 to September 2006. One hundred and eight adult patients were included in the study, 46% of whom younger than 25 years, and 72.5% were admitted from May to September. Patients were tested for antibodies to Rickettsia conorii conorii, R. conorii israelensis, R. aeschlimannii, R. felis, R. sibirica mongolitimonae, R. africae, R. massiliae, R. typhi, and R. prowazekii using microimmunofluorescence and Western blot as confirmation procedure. Both methods confirmed the diagnosis of Mediterranean spotted fever in 5 patients (4.6%), flea spotted fever in 2 patients (1.9%), and R. aeschlimannii infection in 2 patients (1.9%). In addition, 4 patients were diagnosed as having murine typhus (3.7%) and one with epidemic typhus (0.9%). To the best of our knowledge, this is the first report of R. felis infection and R. aeschlimannii infection in Algeria. In conclusion, at least 5 different kinds of rickettsiosis coexist in eastern Algeria and, being responsible for 13% of cases of febrile exanthemas, should be considered among major causes of this clinical picture in this area. In addition, we emphasize the high incidence of typhus group rickettioses, including epidemic typhus, in this area. Copyright © 2012 Elsevier GmbH. All rights reserved.

    Full Text Available This study was carried out on a sample of 224 farms in the southern region of Sétif-Algeria, aimed to identify the different typologies and the agricultural changes caused by the climatic constrains experienced in recent decades. Indeed, the combined effect of climatic and anthropogenic factors on agricultural practices transitions is too tangled. A series of multivariate and classification statistical tests have been implemented to demonstrate the main trends and adaptation tactics of farmers in such conditions. The farming characterization analysis showed that the medium scale farming was more economically efficient than small and large scale farming. Moreover, the study showed the effect of climate change on some farming transitions, where farming practices transited to bovine and poultry farming as well as for market gardening cultivation. Indeed, these changes were occurred at the expense of rainfed agriculture (cereals and ovine breeding. These transitions have impacted the economic performance of farms in some municipalities. However, greenhouse crops and tobacco cultivation were observed as being a Local Production Systems (LPS that could be a good alternative to mitigate the natural and socioeconomic constraints. The emergence of Local Production Systems in agricultural system may facilitate farmer adaptation that will provide a tool for agricultural development policies, through financial and technical assistance.

  17. Aridification of the Sahara desert caused by Tethys Sea shrinkage during Late Miocene

    Science.gov (United States)

    Zhang, Z.; Ramstein, G.; Schuster, M.; Li, C.; Contoux, C.; Yan, Q.

    2014-12-01

    It is widely believed that the Sahara desert is no more than ~2-3 million years (Myr) old, with geological evidence showing a remarkable aridification of north Africa at the onset of the Quaternary ice ages. Before that time, north African aridity was mainly controlled by the African summer monsoon (ASM), which oscillated with Earth's orbital precession cycles. Afterwards, the Northern Hemisphere glaciation added an ice volume forcing on the ASM, which additionally oscillated with glacial-interglacial cycles. These findings led to the idea that the Sahara desert came into existence when the Northern Hemisphere glaciated ~2-3 Myr ago. The later discovery, however, of aeolian dune deposits ~7 Myr old suggested a much older age, although this interpretation is hotly challenged and there is no clear mechanism for aridification around this time. Here we use climate model simulations to identify the Tortonian stage (~7-11 Myr ago) of the Late Miocene epoch as the pivotal period for triggering north African aridity and creating the Sahara desert. Through a set of experiments with the Norwegian Earth System Model and the Community Atmosphere Model, we demonstrate that the African summer monsoon was drastically weakened by the Tethys Sea shrinkage during the Tortonian, allowing arid, desert conditions to expand across north Africa. Not only did the Tethys shrinkage alter the mean climate of the region, it also enhanced the sensitivity of the African monsoon to orbital forcing, which subsequently became the major driver of Sahara extent fluctuations. These important climatic changes probably caused the shifts in Asian and African flora and fauna observed during the same period, with possible links to the emergence of early hominins in north Africa.

  18. Disaster Metrics: A Comprehensive Framework for Disaster Evaluation Typologies.

    Science.gov (United States)

    Wong, Diana F; Spencer, Caroline; Boyd, Lee; Burkle, Frederick M; Archer, Frank

    2017-10-01

    Introduction The frequency of disasters is increasing around the world with more people being at risk. There is a moral imperative to improve the way in which disaster evaluations are undertaken and reported with the aim of reducing preventable mortality and morbidity in future events. Disasters are complex events and undertaking disaster evaluations is a specialized area of study at an international level. Hypothesis/Problem While some frameworks have been developed to support consistent disaster research and evaluation, they lack validation, consistent terminology, and standards for reporting across the different phases of a disaster. There is yet to be an agreed, comprehensive framework to structure disaster evaluation typologies. The aim of this paper is to outline an evolving comprehensive framework for disaster evaluation typologies. It is anticipated that this new framework will facilitate an agreement on identifying, structuring, and relating the various evaluations found in the disaster setting with a view to better understand the process, outcomes, and impacts of the effectiveness and efficiency of interventions. Research was undertaken in two phases: (1) a scoping literature review (peer-reviewed and "grey literature") was undertaken to identify current evaluation frameworks and typologies used in the disaster setting; and (2) a structure was developed that included the range of typologies identified in Phase One and suggests possible relationships in the disaster setting. No core, unifying framework to structure disaster evaluation and research was identified in the literature. The authors propose a "Comprehensive Framework for Disaster Evaluation Typologies" that identifies, structures, and suggests relationships for the various typologies detected. The proposed Comprehensive Framework for Disaster Evaluation Typologies outlines the different typologies of disaster evaluations that were identified in this study and brings them together into a single

    Full Text Available Diverse crocodyliforms have been discovered in recent years in Cretaceous rocks on southern landmasses formerly composing Gondwana.  We report here on six species from the Sahara with an array of trophic adaptations that significantly deepen our current understanding of African crocodyliform diversity during the Cretaceous period.  We describe two of these species (Anatosuchus minor, Araripesuchus wegeneri from nearly complete skulls and partial articulated skeletons from the Lower Cretaceous Elrhaz Formation (Aptian-Albian of Niger. The remaining four species (Araripesuchus rattoides sp. n., Kaprosuchus saharicus gen. n. sp. n., Laganosuchus thaumastos gen. n. sp. n., Laganosuchus maghrebensis gen. n. sp. n. come from contemporaneous Upper Cretaceous formations (Cenomanian in Niger and Morocco.

    In Algeria, the treatment of visceral and cutaneous leishmanioses (VL and CL) has been and continues to be based on antimony-containing drugs. It is suspected that high drug selective pressure might favor the emergence of chemoresistant parasites. Although treatment failure is frequently reported during antimonial therapy of both CL and VL, antimonial resistance has never been thoroughly investigated in Algeria. Determining the level of antimonial susceptibility, amongst Leishmania transmitted in Algeria, is of great importance for the development of public health policies. Within the framework of the knowledge about the epidemiology of VL and CL amassed during the last 30 years, we sampled Leishmania isolates to determine their susceptibility to antimony. We analyzed a total of 106 isolates including 88 isolates collected between 1976 and 2013 in Algeria from humans, dogs, rodents, and phlebotomines and 18 collected from dogs in France. All the Algerian isolates were collected in 14 localities where leishmaniasis is endemic. The 50% inhibitory concentrations (IC50) of potassium antimony tartrate (the trivalent form of antimony, Sb(III)) and sodium stibogluconate (the pentavalent form of antimony, Sb(V)) were determined in promastigotes and intramacrophage amastigotes, respectively. The epidemiological cutoff (ECOFF) that allowed us to differentiate between Leishmania species causing cutaneous or visceral leishmaniases that were susceptible (S+) or insusceptible (S-) to the trivalent form of antimony was determined. The computed IC50 cutoff values were 23.83 μg/mL and 15.91 μg/mL for VL and CL, respectively. We report a trend of increasing antimony susceptibility in VL isolates during the 30-year period. In contrast, an increase in the frequency of S- phenotypes in isolates causing CL was observed during the same period. In our study, the emergence of S- phenotypes correlates with the inclusion of L. killicki (syn: L. tropica) isolates that cause cutaneous

    Full Text Available We report clinical and pathological features of enzootic nasal adenocarcinoma (ENA in one sheep in Algeria. A one-year-old Ouled Djellal sheep from a large herd (~1240 animals, located in Bordj Bou Arreridj, Algeria, was clinically diagnosed by the presence of persistent seromucous nasal discharge, head shaking, muzzle licking, dyspnoea, exophthalmia and frontal protrusion. The sheep was euthanized, and the necropsy was performed. Gross examination showed soft touch, pinkish-white tumour masses in the nasal cavities with distortion of the turbinates and of the medium septum. According to clinical and pathological findings, the tumour has been defined as a low grade mixed nasal adenocarcinoma, with the presence of tubular and papillary structures. This is, to our knowledge, the first report of ENA in Algeria known to be associated with enzootic nasal tumour virus (ENTV infection. However, such association requires confirmation by direct and/or indirect viral investigation.

    During the 1970's, thanks to oil exploitation income, Algeria, Iraq and Libya seemed to be engaged in an accelerated modernization process. Petroleum was the blessing that would allow these states to catch up on their economic gap. Algeria was introduced as a 'Mediterranean dragon', Libya as an 'emirate' and Iraq as the leading military power of the Arab world. On the political side, the progressive socialism made one think that deep social transformations were in progress. Several decades later, the disappointment is painful. The prosperity feeling has led these countries into political, economic and military impasses with disastrous consequences for their populations. This book analyses the reasons that have led to this political/economical/social situation. The questions are: how can these countries get rid of deep reforms without any risk of social explosion, and how can the European Union export its standards and values and protect its gas imports at the same time?

    Full Text Available Verticillium wilt of olive trees (Olea europaea L., a wilt caused by the soil-borne fungus Verticillium dahliae (Kleb, is one of the most serious diseases in Algerian olive groves. To assess the pathogenic and genetic diversity of olive-infecting V. dahliae populations in Algeria, orchards from the two main olive-producing regions (north-western Algeria and Kabylia were sampled and 27 V. dahliae isolates were recovered. For purposes of comparison, V. dahliae strains from France and Syria were added to the analysis. By means of PCR primers that specifically discriminate between defoliating (D and non-defoliating (ND V. dahliae pathotypes it was shown that all V. dahliae isolates belonged to the ND pathotype. The amount of genetic variation between the 43 isolates was assessed by random amplification of polymorphic DNA (RAPD. A total of 16 RAPD haplotypes were found on the basis of the presence or absence of 25 polymorphic DNA fragments. Genotypic diversity between the 27 Algerian isolates was low, with two RAPD haplotypes accounting for 70% of all isolates. Genotypic diversity was however greater between isolates from Kabylia than between isolates from north-western Algeria. Cluster analysis showed that most of the Algerian V. dahliae isolates grouped together with the French and Syrian isolates. On the basis of their ability to form heterokaryons with each other, a subset of 25 olive-pathogenic isolates was grouped into a single vegetative compatibility group (VCG. These results suggest that the olive-infecting V. dahliae populations in Algeria show limited diversity and that caution should be taken to prevent introduction of the D pathotype.

    After having outlined that Algeria possesses one of the most promising geologies regarding oil, gas and shale gas proved and possible reserves, but that conditions imposed to the private sector are such that investments have been decreasing, thus leaving Sonatrach, the national public company, almost alone do develop this oil and gas patrimony, and after having recalled that the world oil sector is facing a major crisis since the collapse of oil prices in 2014, the author proposes an analysis of this situation of lack of interest of private companies in Algeria, and a discussion of the consequences for Sonatrach. He comments results published by this company in terms of drilling activities, notices the very low percentage of private drilling activities, outlines that Sonatrach is facing a very difficult situation (many contractors to be paid, collapse of revenues, and increased consumption) which may impede its ambitious exploration project for the years to come. The author also comments results of the bidding processes which have been disappointing for the last ten years. He outlines that financial scandals and arbitrations contributed to the loss of confidence of foreign oil companies. He comments how projects have been developed during these last ten years, and discusses the strategy envisaged for the exploitation of shale gases

    Full Text Available The double-tract unit is a rather rare typological shape in residential architecture in the world, and this is why it has not been explored extensively in the field of habitology, although it is known that the first examples of double-tract units in multi- family dwellings were implemented back in XIX century. Every attempt at typology depends on the angle of analysis of a given subject, as well as the selection and hierarchy of the criteria and categorization of individual elements. This makes it hard to tell whether it is feasible to establish universal typology for all architectural patterns. Typology of residential types in architecture is mostly set according to current patterns (most often, only those that were executed. However, since the shape of double-tract unit is quite rare in the world, in most cases it was not even recorded, and even when it was, it was most often included as part of some other category or terminological definition. The aim of this paper is to outline the typology for the double-tract units in multi-family dwellings with an overview of current, established patterns (designed and executed, but also those which could yet be taken into consideration.

    The aim of this study is to evaluate the cost-effectiveness of ECG in combination with family and personal history and physical examination in order to detect cardiovascular diseases that might cause sudden death in athletes. The study was conducted on a cohort of 6,634, mainly young professional and recreational athletes, 1,071 from Algeria and 5,563 from Europe (France, Germany and Greece). Each athlete underwent medical history, physical examination, and resting 12-lead ECG. 293 athletes (4.4 %), 149 in Europe (2.7 %) and 144 in Algeria (13.4 %) required further tests, and 56 were diagnosed with cardiovascular disease and thus disqualified. The cost-effectiveness ratio (CER) was calculated as the ratio between the cost of screening and the number of statistical life-years saved by the intervention. The estimated reduced risk of death deriving from treatment or disqualification resulted in the saving of 79.1 statistical life-years in Europe and 136.3 in Algeria. CER of screening was 4,071 purchasing-power-parity-adjusted US dollars ($PPP) in Europe and 582 $PPP in Algeria. The results of this study strongly support the utilisation of 12-lead ECG in the pre-participation screening of young athletes, especially in countries where secondary preventive care is not highly developed.

  10. Typology reconfigured: from the metaphysics of essentialism to the epistemology of representation.

    Love, Alan C

    2009-06-01

    The goal of this paper is to encourage a reconfiguration of the discussion about typology in biology away from the metaphysics of essentialism and toward the epistemology of classifying natural phenomena for the purposes of empirical inquiry. First, I briefly review arguments concerning 'typological thinking', essentialism, species, and natural kinds, highlighting their predominantly metaphysical nature. Second, I use a distinction between the aims, strategies, and tactics of science to suggest how a shift from metaphysics to epistemology might be accomplished. Typological thinking can be understood as a scientific tactic that involves representing natural phenomena using idealizations and approximations, which facilitates explanation, investigation, and theorizing via abstraction and generalization. Third, a variety of typologies from different areas of biology are introduced to emphasize the diversity of this representational reasoning. One particular example is used to examine how there can be epistemological conflict between typology and evolutionary analysis. This demonstrates that alternative strategies of typological thinking arise due to the divergent explanatory goals of researchers working in different disciplines with disparate methodologies. I conclude with several research questions that emerge from an epistemological reconfiguration of typology.

  11. Sustainable operations management: A typological approach

    Directory of Open Access Journals (Sweden)

    Lawrence Michael Corbett

    2009-07-01

    Full Text Available This paper discusses the nature of sustainability and sustainable development as they relate to operations management. It proposes a typology for sustainable operations management that is based on the life cycle stages of a product and the three dimensions of corporate social responsibility. The aim is to show how this typology development could provide a useful approach to integrating the diverse strands of sustainability in operations, using industrial ecology and carbon neutrality as examples. It does this by providing a focused subset of environmental concerns for an industrial ecology approach, and some research propositions for the issue of carbon neutrality.

  12. Grene and Hull on types and typological thinking in biology.

    2015-04-01

    Marjorie Grene (1910-2009) and David Hull (1935-2010) were among the most influential voices in late twentieth-century philosophy of biology. But, as Grene and Hull pointed out in published discussions of one another's work over the course of nearly forty years, they disagreed strongly on fundamental issues. Among these contested issues is the role of what is sometimes called "typology" and "typological thinking" in biology. In regard to taxonomy and the species problem, Hull joined Ernst Mayr's construal of typological thinking as a backward relic of pre-Darwinian science that should be overcome. Grene, however, treated the suspicion of typological thinking that characterized Hull's views, as well as those of other architects of the New Evolutionary Synthesis, as itself suspicious and even unsustainable. In this paper I review three debates between Grene and Hull bearing on the question of the validity of so-called typological thinking in biology: (1) a debate about the dispensability of concepts of "type" within evolutionary theory, paleontology, and taxonomy; (2) a debate about whether species can be adequately understood as individuals, and thereby independently of those forms of thinking Hull and Mayr had construed as "typological"; and (3) a debate about the prospects of a biologically informed theory of human nature.

  16. Aridification of the Sahara desert caused by Tethys Sea shrinkage during the Late Miocene

    It is widely believed that the Sahara desert is no more than ~2-3 million years (Myr) old, with geological evidence showing a remarkable aridification of north Africa at the onset of the Quaternary ice ages. Before that time, north African aridity was mainly controlled by the African summer monsoon (ASM), which oscillated with Earth's orbital precession cycles. Afterwards, the Northern Hemisphere glaciation added an ice volume forcing on the ASM, which additionally oscillated with glacial-interglacial cycles. These findings led to the idea that the Sahara desert came into existence when the Northern Hemisphere glaciated ~2-3 Myr ago. The later discovery, however, of aeolian dune deposits ~7 Myr old suggested a much older age, although this interpretation is hotly challenged and there is no clear mechanism for aridification around this time. Here we use climate model simulations to identify the Tortonian stage (~7-11 Myr ago) of the Late Miocene epoch as the pivotal period for triggering north African aridity and creating the Sahara desert. Through a set of experiments with the Norwegian Earth System Model and the Community Atmosphere Model, we demonstrate that the African summer monsoon was drastically weakened by the Tethys Sea shrinkage during the Tortonian, allowing arid, desert conditions to expand across north Africa. Not only did the Tethys shrinkage alter the mean climate of the region, it also enhanced the sensitivity of the African monsoon to orbital forcing, which subsequently became the major driver of Sahara extent fluctuations. These important climatic changes probably caused the shifts in Asian and African flora and fauna observed during the same period, with possible links to the emergence of early hominins in north Africa.

    Although there is a consensus that there were wet periods (greening events) in the Sahara in the past, the spatial extent and the timing of these greening events are still in dispute, yet critical to our understanding of the early human dispersal out of Africa. Our U-series dates of speleothems from the Northeastern Sahara (Wadi Sannur cave, Egypt) reveal that the periods of speleothem growth were brief and restricted to the interglacial Marine Isotope Stages MIS 5.5, MIS 7.3, and the early MIS 9 with a remarkable absence of the Holocene deposition of speleothems. These growth periods of Wadi Sannur cave speleothems correspond to periods of high rainfall and spread of vegetation (green Sahara). Distinct low δ18O values of speleothems indicate a distal moisture source that we interpret to be the Atlantic Ocean. These two lines of evidence from the Wadi Sannur speleothems thus suggest that maximal northward shifts in the West African monsoon system occurred during the growth periods of the speleothems, leading to greening of the Sahara, facilitating human migration into Eurasia. The periods of speleothem growth at Wadi Sannur cave are contemporaneous with important archeological events: (1) the earliest occurrence of the Middle Stone Age assemblages and Homo sapiens in North Africa (Jebel Irhoud), suggesting wide spread of greening conditions over the East-West transect of the Sahara, (2) the sharp technological break between the Acheulo-Yabrudian and the Mousterian industries, and (3) the arrival of Homo sapiens in Levant, indicating a key role of the Sahara route in early human dispersal out of Africa.

  3. Carbon dioxide emissions, output, and energy consumption categories in Algeria.

    2017-06-01

    This study examines the relation between CO 2 emissions, income, non-renewable, and renewable energy consumption in Algeria during the period extending from 1980 to 2011. Our work gives particular attention to the validity of environmental Kuznets curve (EKC) hypothesis. The autoregressive distributed lag (ARDL) with break point method outcome demonstrates the positive effect of non-renewable type of energy on CO 2 emissions consumption. On the contrary, the results reveal an insignificant effect of renewable energy on environment improvement. Moreover, the results accept the existence of EKC hypothesis but the highest gross domestic product value in logarithm scale of our data is inferior to the estimated turning point. Consequently, policy-makers in Algeria should expand the ratio of renewable energy and should decrease the quota of non-renewable energy consumption.

From a time series which consists of information on agricultural production and means of production were obtained from FAO AGROSTAT and rainfall data from Steve O’Connell data base. The information was for a 43-year period (1961-2003; DEA method was used to measure Malmquist index of total factor productivity. A decomposition of TFP measures revealed that the observed increase in the TFP in the sub–Sahara Africa agriculture is due to technological change rather than efficiency change which is the main constrained of achieving higher level of TFP during the reference period. The study further examined the effect of land quality, malaria, education and selected governance indicators such as, control of corruption and government effectiveness on productivity growth. All the variables included in the model are significant with the exception of government effectiveness

    The painted lady, Vanessa cardui, is a migratory butterfly that performs an annual multi-generational migration between Europe and North Africa. Its seasonal appearance south of the Sahara in autumn is well known and has led to the suggestion that it results from extremely long migratory flights by European butterflies to seasonally exploit the Sahel and the tropical savannah. However, this possibility has remained unproven. Here, we analyse the isotopic composition of butterflies from seven European and seven African countries to provide new support for this hypothesis. Each individual was assigned a geographical natal origin, based on its wing stable hydrogen isotope (δ 2 H w ) value and a predicted δ 2 H w basemap for Europe and northern Africa. Natal assignments of autumn migrants collected south of the Sahara confirmed long-distance movements (of 4000 km or more) starting in Europe. Samples from Maghreb revealed a mixed origin of migrants, with most individuals with a European origin, but others having originated in the Sahel. Therefore, autumn movements are not only directed to northwestern Africa, but also include southward and northward flights across the Sahara. Through this remarkable behaviour, the productive but highly seasonal region south of the Sahara is incorporated into the migratory circuit of V. cardui. © 2016 The Author(s).

    2018-01-01

    This paper examines the possible relationship between proposed social determinants of morphological 'complexity' and how this contributes to linguistic diversity, specifically via the typological nature of the sign languages of deaf communities. We sketch how the notion of morphological complexity, as defined by Trudgill (2011), applies to sign languages. Using these criteria, sign languages appear to be languages with low to moderate levels of morphological complexity. This may partly reflect the influence of key social characteristics of communities on the typological nature of languages. Although many deaf communities are relatively small and may involve dense social networks (both social characteristics that Trudgill claimed may lend themselves to morphological 'complexification'), the picture is complicated by the highly variable nature of the sign language acquisition for most deaf people, and the ongoing contact between native signers, hearing non-native signers, and those deaf individuals who only acquire sign languages in later childhood and early adulthood. These are all factors that may work against the emergence of morphological complexification. The relationship between linguistic typology and these key social factors may lead to a better understanding of the nature of sign language grammar. This perspective stands in contrast to other work where sign languages are sometimes presented as having complex morphology despite being young languages (e.g., Aronoff et al., 2005); in some descriptions, the social determinants of morphological complexity have not received much attention, nor has the notion of complexity itself been specifically explored.

    Full Text Available This paper examines the possible relationship between proposed social determinants of morphological ‘complexity’ and how this contributes to linguistic diversity, specifically via the typological nature of the sign languages of deaf communities. We sketch how the notion of morphological complexity, as defined by Trudgill (2011, applies to sign languages. Using these criteria, sign languages appear to be languages with low to moderate levels of morphological complexity. This may partly reflect the influence of key social characteristics of communities on the typological nature of languages. Although many deaf communities are relatively small and may involve dense social networks (both social characteristics that Trudgill claimed may lend themselves to morphological ‘complexification’, the picture is complicated by the highly variable nature of the sign language acquisition for most deaf people, and the ongoing contact between native signers, hearing non-native signers, and those deaf individuals who only acquire sign languages in later childhood and early adulthood. These are all factors that may work against the emergence of morphological complexification. The relationship between linguistic typology and these key social factors may lead to a better understanding of the nature of sign language grammar. This perspective stands in contrast to other work where sign languages are sometimes presented as having complex morphology despite being young languages (e.g., Aronoff et al., 2005; in some descriptions, the social determinants of morphological complexity have not received much attention, nor has the notion of complexity itself been specifically explored.

    Full Text Available The present study aimed to document and analyze the local knowledge of medicinal plants’ use by traditional healers in South-west Algeria. The ethnobotanical survey was conducted in two Saharian regions of South-west of Algeria: Adrar and Bechar. In total, twenty-two local traditional healers were interviewed using semi-structured questionnaire and open questions. Use value (UV, fidelity level (FL and Informant Consensus Factor (FIC were used to analyze the obtained data. Our results showed that 83 medicinal plants species belonging to 38 families are used by traditional healers from South-west of Algeria to treat several ailments. Lamiaceae, Asteraceae, Apiaceae and Fabaceae were the most dominant families with 13, 8, 6 and 4 species respectively. Leaves were the plant parts mostly used (36%, followed by seeds (18%, aerial parts (17% and roots (12%. Furthermore, decoction was the major mode of preparation (49% and oral administration was the most preferred (80%. Thymus vulgaris L. (UV=1.045, Zingiber officinale (UV=0.863, Trigonella foenum-graecum L. (UV=0.590, Rosmarinus officinalis L. (UV=0.545 and Ruta chalepensis L. (UV=0.5 were the most frequently species used by local healers. A great informant consensus has been demonstrated for kidney (0.727, cancer (0.687, digestive (0.603 and respiratory diseases. The present study revealed rich ethnomedicinal knowledge in South-west Algeria. The reported species with high use-value, fidelity level and informant consensus factor could be of great interest for further pharmacological studies. [J Complement Med Res 2016; 5(4.000: 320-330

    1994-10-14

    A major question in Mesozoic biogeography is how the land-based dinosaurian radiation responded to fragmentation of Pangaea. A rich fossil record has been uncovered on northern continents that spans the Cretaceous, when continental isolation reached its peak. In contrast, dinosaur remains on southern continents are scarce. The discovery of dinosaurian skeletons from Lower Cretaceous beds in the southern Sahara shows that several lineages of tetanuran theropods and broad-toothed sauropods had a cosmopolitan distribution across Pangaea before the onset of continental fragmentation. The distinct dinosaurian faunas of Africa, South America, and Asiamerica arose during the Cretaceous by differential survival of once widespread lineages on land masses that were becoming increasingly isolated from one another.

    When, after years of geological and geophysical exploration, a phosphate mine was discovered at Bu-Craa in 1964, Western Sahara received renewed geopolitical attention. Several countries competing for the control of the world fertilizer market, including Morocco, Spain, France, and the United States, developed diverging strategies to gain control of the mineral. After intense negotiations revolving around the materiality of mining technologies and involving reserve estimations, sabotage, and flexing of diplomatic muscles, Morocco took over the Spanish colony in 1975. While this secured Morocco's place in the world market, it condemned the local population to exile and domination. This article explores three technological stages of the exploitation of phosphate in Western Sahara that underpin the geopolitical history. This perspective yields new visions of cold war technology and postcolonial markets.

  20. Pluvial Phases In The Sahara During The Holocene: A Multi-disciplinary Comparison

    Science.gov (United States)

    Barnikel, F.; Becht, M.

    The understanding of low latitude palaeoclimatic dynamics is incomplete without a thorough analysis of the wide-spread fluctuations between humid and arid phases in the Sahara. It is especially the holocene that has been scrutinized in respect to lake and river deposits, pollen analysis, macrorest analysis, groundwater dating, remote sensing, pedology, archaeology and even glottochronology. During the last decades a lot of teams from different countries (e.g. French in the west and south, Germans in the south and east, Americans, Italians and Polish in the east and many more) have evaluated numerous data gained from different disciplines all over the Sahara. Inten- sive work has shed new light on climate dynamics especially in the eastern part. But even there, as in other parts as well, the data are insufficient to explain palaeoclimatic variability to a satisfying degree. Meticulous analysis of the published data has shown grave inconsistencies between the different disciplines concerning dates for pluvial phases (differences up to several millenia), the intensity of rainfall, the face of the palaeoenvironment and the like. Our aim is to show the areas that lack sufficient data and to point out the huge problems that arise from the differing research results in other parts. Since a valid assessment of holocene palaeoclimatic dynamics for large parts of the globe is unthinkable without a proper understanding of emergence, form and ending of pluvial phases in the Sahara, more multi-disciplinary work is neces- sary. Furthermore, all data, especially the radiocarbon datings, need to be collected and made accessible for all disciplines in a data bank.

Lebanese Science Journal. 18(1: 26-46. Until now, the research undertaken in Algeria on controlling Planococcus ficus or mealybug, a pest responsible of high level of damages on vines, were very limited. A study on the spatiotemporal dynamics of the pest was conducted for three years in the vineyards of the Western Mitidja in Algeria. The weekly sampling of leaves and clusters were carried out from 2006 to 2008, on wine and table grapes. A high contamination by P. ficus was observed in summer and the beginning of autumn depending on the varieties and years. The monitoring system showed the development of 5 to 6 successive peaks on leaves, and 3 to 4 successive peaks on grape clusters.

  3. Typology in pollination biology: Lessons from an historical critique

    Directory of Open Access Journals (Sweden)

    Andreas Erhardt

    2011-03-01

    Full Text Available Typological schemes that describe putative floral adaptations for pollinators have played a central role in pollination biology. In 1882 the prominent German botanist and Darwinist Hermann Müller commented critically on a precursor of modern versions of such “pollination syndromes” that had been developed by his Italian colleague Federico Delpino. Delpino also was a self-proclaimed Darwinist, but in fact adhered to teleology—explanation beyond nature. As a consequence he viewed his typology as reflecting a deeper ideal and thus as rigidly true, and rejected as unimportant any visitors to flowers that it did not predict. Although Müller also classified flowers as to pollinators, he considered such schemes to be fallible, and pondered what diversity and variation in floral visitors might mean. Müller’s comments, which we translate here, are of interest given that appeals to teleology have resurfaced from time to time in discussions of pollination syndromes, and more importantly because his warning against taking typological schemes too literally remains valid. Typology is a useful tool in biology, including pollination biology, but care must be taken that it does not replace nature as perceived reality.

    Researchers examining personality typologies of posttraumatic stress disorder (PTSD) have consistently identified 3 groups: low pathology, internalizing, and externalizing. These groups have been found to predict functional severity and psychiatric comorbidity. In this study, we employed Latent Profile Analysis to compare this previously established typology, grounded in temperament traits (negative emotionality; positive emotionality; constraint), to a novel typology rooted in interpersonal traits (dominance; warmth) in a sample of individuals with PTSD (n = 155). Using Schedule for Nonadaptive and Adaptive Personality (SNAP) traits to create latent profiles, the 3-group temperament model was replicated. Using Interpersonal Circumplex (IPC) traits to create latent profiles, we identified a 4-group solution with groups varying in interpersonal style. These models were nonredundant, indicating that the depiction of personality variability in PTSD depends on how personality is assessed. Whereas the temperament model was more effective for distinguishing individuals based on distress and comorbid disorders, the interpersonal model was more effective for predicting the chronicity of PTSD over the 10 year course of the study. We discuss the potential for integrating these complementary temperament and interpersonal typologies in the clinical assessment of PTSD. 2014 APA

    A systematic review of studies related to the psychological characteristics of Sasang types was conducted with the goal of delineating generalizable psychological profiles based on Sasang typology, a traditional Korean medical typology with medical herbs and acupuncture that is characterized as personalized medicine. Journal articles pertaining to Sasang typology were collected using five electronic database systems in Korea and in the USA. As a result, 64 potentially relevant studies were identified and 21 peer-reviewed research articles that employed psychometric inventories were included. Beginning with the use of the Minnesota Multiphasic Personality Inventory in 1992, Myers-Briggs Type Indicator, NEO-Personality Inventory, Temperament and Character Inventory and other personality assessment tools were employed in the identified studies. Because data synthesis could not be carried out due to the heterogeneity of the studies, the present review article sought to delineate the mutual relevance of the studies based on research results pertaining to the correlation between the aforementioned psychological assessment instruments. Results of the review indicate that two super-factors, Extraversion and Neuroticism, serve as the foundation in regards to delineating personality constructs, such that the So-Yang type scored high on the Extraversion dimension and low on the Neuroticism dimension, while the So-Eum type scored low on the Extraversion dimension and high on the Neuroticism dimension. The present systematic review indicates that Sasang typology shares similarities with the Western psychological tradition.

    Full Text Available Objective: To investigate the effect of unheated and heat-treated of Sahara honey. Methods: A total of 24 Swiss albino mice weighing 25–35 g were divided into four groups (n = 6. Anti-inflammatory effect was assessed at 1, 2, 3, 4, 5 and 6 h after subplantar injection of carrageenan (0.5 mL of a 1% solution in normal saline. In addition, total phenolic content was determined by modified Folin-Ciocalteu method. Results: The total phenolic content capacity of the Sahara honey before and after heat treatment was between 72 and 97.9 mg of gallic acid equivalents/100 g of honey respectively. Administration of unheated honey (oral administration reduced significantly (P < 0.05. The carrageenan induced mice paw edema model at 1, 3 and 6 h for 21.85%, 5.43% and 80.43%, respectively. Administration of heat-treated honey showed insignificant inhibition of carrageenan and induced paw edema at 1 h (31.16%, 3 h (0.25% and 6 h (34.19%. The 50 mg/kg diclofenac exhibited percent reduction in paw volume 16.12%, 8.90% and 15.32% after 1 h, 3 h and 6 h, respectively, when compared with control animals. No toxicity was identified. Conclusions: Our results suggest that unheated Sahara honey has anti-inflammatory effects by reducing the mice paw edema size while heat-treated Sahara honey decreases the antiinflammatory activity.

    This paper reports that Algeria is positioned to achieve important, new natural gas markets. Over half of its hydrocarbon income is from exports of gas and derived products, liquified petroleum gas (LPG) and condensates, which are not subject to Opec quotas. Officials are moving away from inflexible past policies and are becoming vastly more realistic now that foreign investment laws have been liberalized and there is a need to attract foreign investors. Sonatrach must address three key issues to consolidate recent progress. Sales to existing customers in Europe, like Italy, must be expanded; new customers and markets need to found: and U.S. liquified natural gas (LNG) markets must be revived

A second round will follow next April. Sonatrach plans to drill 200 wells during 1991-95, which will require the current level of 37/year to be almost trebled toward the end of the period. To this end foreign operators are being courted in an open exploration bidding round. Deadline for bid submittal in Nov. 30. Companies may enter singly or in groups to form partnerships with Sonatrach. Foreign licensees will be able to take a maximum 49% of production under Algerian law

  9. How much rainfall sustained a Green Sahara during the mid-Holocene?

    2016-04-01

    The present-day Sahara desert has periodically transformed to an area of lakes and vegetation during the Quaternary in response to orbitally-induced changes in the monsoon circulation. Coupled atmosphere-ocean general circulation model simulations of the mid-Holocene generally underestimate the required monsoon shift, casting doubt on the fidelity of these models. However, the climatic regime that characterised this period remains unclear. To address this, we applied an ensemble of dynamic vegetation model simulations using two different models: JULES (Joint UK Land Environment Simulator) a comprehensive land surface model, and LPJ (Lund-Potsdam-Jena model) a widely used dynamic vegetation model. The simulations are forced with a number of idealized climate scenarios, in which an observational climatology is progressively altered with imposed anomalies of precipitation and other related variables, including cloud cover and humidity. The applied anomalies are based on an ensemble of general circulation model simulations, and include seasonal variations but are spatially uniform across the region. When perturbing precipitation alone, a significant increase of at least 700mm/year is required to produce model simulations with non-negligible vegetation coverage in the Sahara region. Changes in related variables including cloud cover, surface radiation fluxes and humidity are found to be important in the models, as they modify the water balance and so affect plant growth. Including anomalies in all of these variables together reduces the precipitation change required for a Green Sahara compared to the case of increasing precipitation alone. We assess whether the precipitation changes implied by these vegetation model simulations are consistent with reconstructions for the mid-Holocene from pollen samples. Further, Earth System models predict precipitation increases that are significantly smaller than that inferred from these vegetation model simulations. Understanding

    Full Text Available The identification of past glacial refugia has become a key topic for conservation under environmental change, since they contribute importantly to shaping current patterns of biodiversity. However, little attention has been paid so far to interglacial refugia despite their key role for the survival of relict species currently occurring in climate refugia. Here, we focus on the genetic consequences of range contraction on the relict populations of the evergreen shrub Myrtus nivellei, endemic in the Saharan mountains since at least the end of the last Green Sahara period, around 5.5 ka B.P. Multilocus genotypes (nuclear microsatellites and AFLP were obtained from 215 individuals collected from 23 wadis (temporary rivers in the three main mountain ranges in southern Algeria (the Hoggar, Tassili n'Ajjer and Tassili n'Immidir ranges. Identical genotypes were found in several plants growing far apart within the same wadis, a pattern taken as evidence of clonality. Multivariate analyses and Bayesian clustering revealed that genetic diversity was mainly structured among the mountain ranges, while low isolation by distance was observed within each mountain range. The range contraction induced by the last episode of aridification has likely increased the genetic isolation of the populations of M. nivellei, without greatly affecting the genetic diversity of the species as a whole. The pattern of genetic diversity observed here suggests that high connectivity may have prevailed during humid periods, which is consistent with recent paleoenvironmental reconstructions.

    2010-11-01

    Based on systematic observation and analysis of available evidence, we propose a typology of cross-border patient mobility (rather than the so-called 'medical tourism') defined as the movement of a patient travelling to another country to seek planned health care. The typology is constructed around two dimensions based on the questions 'why do patients go abroad for planned health care?' and 'how is care abroad paid for?' Four types of patient motivations and two funding types have been identified. Combined in a matrix, they make eight possible scenarios of patient mobility each illustrated with international examples. Copyright © 2010 Elsevier Ltd. All rights reserved.

    1991-10-01

    Those investigating the nature and functioning of self-help groups have been handicapped by the lack of a conceptual framework to bridge the diversity among such groups as well as to clarify the boundaries between consumer-owned and professionally owned groups. This paper describes a typology that classifies local units of these groups in terms of differences and similarities in their organizational structures. Rooted in organizational theory, it has two dimensions: external dependence upon resources and internal extent of experiential authority. Using it, the authors identified five types of groups, referred to as Unaffiliated, Federated, Affiliated, Hybrid, and Managed. The typology was validated with actual groups.

    2010-01-01

    A person-centered approach was used to explore the mediating role of self-regulation between learner typology at age 8 and academic achievement at age 14while controlling for domain-specific achievement in a longitudinal sample of 113 children born to adolescent mothers. Children were classified into one of 5 learner typologies at age 8based on interactive patterns of intellectual, achievement, and adaptive abilities. Typology classification explained significant variance in both reading and mathematics achievement at age 14. A bootstrapping approach confirmed that self-regulation mediated the relationship between typology and reading and mathematical achievement for children from all typologies except those classified as Cognitively and Adaptively Challenged. Implications of person-centered approaches for understanding processes involved with achievement are discussed. PMID:21278904

    Full Text Available A new species of Cyrtospirifer is described from the Middle to Upper Givetian of the Western Sahara (Northwest Africa. Cyrtospirifer tindoufensis new species differs in its smaller number and coarser medial and flank plications and equibiconvex shell profile from the other Givetian species of Cyrtospirifer that all occur in Europe and to which the new species probably gives rise. The new implications of the proposed phylogeny of the earliest cyrtospiriferids and their origin from the Western Sahara are discussed. The palaeogeographic distribution of the cyrtospiriferids during the Givetian and Frasnian is shown and its migration ways are described considering the global transgression and regression cycles.

    Building on an existing theoretical shared primary care/specialist care framework to (1) develop a unique typology of care for people living with human immunodeficiency virus (HIV) in Ontario, (2) assess sensitivity of the typology by varying typology definitions, and (3) describe characteristics of typology categories. Retrospective population-based observational study from April 1, 2009, to March 31, 2012. A total of 13,480 eligible patients with HIV and receiving publicly funded health care in Ontario. We derived a typology of care by linking patients to usual family physicians and to HIV specialists with five possible patterns of care. Patient and physician characteristics and outpatient visits for HIV-related and non-HIV-related care were used to assess the robustness and characteristics of the typology. Five possible patterns of care were described as low engagement (8.6%), exclusively primary care (52.7%), family physician-dominated comanagement (10.0%), specialist-dominated comanagement (30.5%), and exclusively specialist care (5.2%). Sensitivity analyses demonstrated robustness of typology assignments. Visit patterns varied in ways that conform to typology assignments. We anticipate this typology can be used to assess the impact of care patterns on the quality of primary care for people living with HIV. Copyright © 2015 Elsevier Inc. All rights reserved.

    Algeria has created a green momentum by launching an ambitious program to develop renewable energies and promote energy efficiency. Solid waste is one of most important sources of biomass potential in Algeria, which can be used as renewable energy sources. With economic development and the evolution of population, the quantity of solid waste is increasing rapidly in Algeria; according to the National Cadastre for Solid Waste Generation, the overall generation of municipal solid waste was more than 10.3 million tons per year, and the amount of industrial solid waste, including non-hazardous and inert industrial waste was 2,547,000 tons per year, with a stock quantity of 4,483,500 tons. The hazardous waste generated amounts to 325,100 tons per year; the quantities of waste in stock and awaiting a disposal solution amount to 2,008,500 tons. Healthcare waste reaches to 125,000 tons per year. The management of solid waste and its valorization is based on the understanding of solid waste composition by its categories and physicochemical characteristics. Elimination is the solution applied to 97% of waste produced in Algeria. Wastes are disposed in the following ways: open dumps (57%), burned in the open air in public dumps or municipal uncontrolled ones (30%), and controlled dumps and landfill (10%). On the other side, the quantities destined for recovery are too low: only 2% for recycling and 1% for composting. Waste to energy is very attractive option for elimination solid waste with energy recovery. In this paper, we give an overview for this technology, including its conversion options and its useful products (such as electricity, heat and transportation fuel), and waste to energy-related environmental issues and its challenges.

    2017-02-01

    The study provides a detailed analysis of the energy production and consumption in Algeria and the associated CO2 emissions. Algeria is an important energy producer (oil and natural gas). The production is currently around 155 MToe. The total primary energy consumption amounted to about 58 MToe equivalent to 1.46 Toe/capita. The energy demand is still increasing, an average annual growth rate of more than 6% per year during the last decade. The growth rate for electricity production was almost twice that of the total energy consumption. In 2015, the installed capacity of the electricity generation plants reached 17.6 GW. Electricity consumption was 64.6 TWh and is expected to reach at least 75 TWh in 2020 and 130 TWh in 2030. The already high electricity demand will double by 2030. In the structure of final energy consumption, the transport sector ranks first (36%), natural gas consumption ranks second (28.5%), followed by electricity production (27.7%). By activity, the energy sector is the main source of CO2 emissions, about ¾ of the total and this sector has the most important potential for mitigation measures. CO2 emissions from this energy sector amounted to 112.2 MT CO2 as follows: 33% transport, 31% electricity production and 26% from natural gas combustion for residential use. The integration of renewable sources in the energy mix represents for Algeria a major challenge. In 2015, Algeria adopted an ambitious program for development of renewable energy. The target is to achieve 22 GW capacity of electricity from renewable by 2030 to reach a rate of 27 % of national electricity generation through renewable sources. By implementing this program, CO2 emissions of power generation will be reduced by more than 18% in 2030.

  10. Impacts of climate variability and change on crop yield in sub-Sahara Africa

    Much concern has been raised about the impacts of climate change and climate extremes on Africa's food security. The impact of climate change on Africa's agriculture is likely to be severe compared to other continents due to high rain-fed agricultural dependence, and limited ability to mitigate and adapt to climate change. In recent decades, warming in Africa is more pronounced and faster than the global average and this trend is likely to continue in the future. However, quantitative assessment on impacts of climate extremes and climate change on crop yield has not been well investigated yet. By using an improved agricultural module of the Dynamic Land Ecosystem Model (DLEM-AG2) driven by spatially-explicit information on land use, climate and other environmental changes, we have assessed impacts of historical climate variability and future climate change on food crop yield across the sub-Sahara Africa during1980-2016 and the rest of the 21st century (2017-2099). Our simulated results indicate that African crop yield in the past three decades shows an increasing trend primarily due to cropland expansion. However, crop yield shows substantially spatial and temporal variation due to inter-annual and inter-decadal climate variability and spatial heterogeneity of environmental drivers. Droughts have largely reduced crop yield in the most vulnerable regions of Sub-Sahara Africa. Future projections with DLEM-AG2 show that food crop production in Sub-Sahara Africa would be favored with limiting end-of-century warming to below 1.50 C.

    After having outlined that the access to information on activities and projects of companies committed in the exploration and exploitation of non conventional hydrocarbons is generally very difficult in European countries, and that opacity is almost absolute in Maghreb countries, the authors try to shed a light on these activities in Algeria. They first outline that Total and GDF-Suez are both giant gas companies which are well settled in Algeria, and that Europe and France are top clients of Algeria as far as gas is concerned. They also notice that, as authorized by a new law and in reference with announced reserves, negotiations will take place between the Sonatrach (the public Algerian oil and gas company) and international firms. They finally briefly outline the various environmental threats associated with this exploitation (threat on agriculture, water pollution), and notices that, even though it somehow supports these activities, Europe is saying that it supports a Mediterranean sustainable development

    1999-12-01

    During the military administration of Algeria, which lasted for forty years, the foundation of the French colony was laid. Indispensable to the military in Algeria was its sizable medical corps. While the ostensible reason for its presence was to maintain the soldiers' health and thus the army's efficiency, it role extended beyond this primary objective. Starting from the intellectual and political influences that shaped the training in France of the members of the medical corps, this essay examines the ways in which they contributed to the creation of a French colonial space in Algeria. It traces how their involvement in the intellectual, cultural, and political life of the colony enabled them both to further their own ambitions and to influence wider developments. It explores how colonial physicians and surgeons, deemed to be among the most efficient agents of the civilizing mission owing to their humane contacts with the indigenous population, in fact contributed to that population's categorization and marginalization.

  15. The heterogeneity of socially isolated older adults: a social isolation typology.

    Science.gov (United States)

    Machielse, Anja

    2015-01-01

    Recent statistics show a growing number of older adults who are living alone and are socially isolated. It is against this background that, in recent years, many interventions have been developed to address social isolation among the elderly. Evaluative studies show that most interventions are hardly effective, though. An important reason for this is the heterogeneity of the socially isolated. This article offers insight into this heterogeneity by presenting a typology with different profiles of socially isolated older adults and the intervention implications of this typology. The typology is derived from an extensive qualitative study on socially isolated elderly individuals in the Netherlands. The typology imposes some degree of order to a diversity of circumstances, ambitions, and possibilities of the socially isolated elderly, thereby deepening the understanding of the heterogeneity of this population. The definition of social isolation used in this study starts from a societal angle of incidence, namely the current policy context of Western European welfare states, in which governments emphasize the importance of independence and self-reliance of their citizens. Developed from that perspective, the typology provides a theoretical basis for applying interventions aimed at increasing self-reliance of social isolated elderly. This perspective on social isolation also has consequences for the way in which the effectiveness of interventions to alleviate social isolation is assessed.

    2013-01-01

    The Algerian economy is an example of a high level of rentierism, while the Egyptian economy shows a low/moderate level of rentierism. The ARDL bounds test approach was used upon annual time series data from 1965 to 2010. The results suggest cointegration for both countries. Bi-causality between energy consumption and growth in the long run was found. For Algeria there is a reversed (negative) energy–growth nexus, adding a new relationship to the traditional four causal hypotheses on the energy–growth nexus. For Egypt, we found positive elasticity both of oil price and energy, which is in line with the mainstream. - Highlights: • We examine the energy–growth nexus within rentierism phenomenon, by applying an ARDL bounds tests approach. • The ARDL reveals to be a suitable tool within the context of analysis of semi-rentier (Egypt) and rentier (Algeria) economies. • The results for Egypt are closer to a conventional economy, supporting the feedback hypothesis. • The results for Algeria are quite different, given that the energy–growth relationship is negative. • The degree of rentierism can influence the nature of the energy–growth nexus

    The objectives of this study were to (1) conduct an elemental characterization of airborne particles sampled in Cape Verde and (2) assess the influence of Sahara desert on local suspended particles. Particulate matter (PM(10)) was collected in Praia city (14°94'N; 23°49'W) with a low-volume sampler in order to characterize its chemical composition by k0-INAA. The filter samples were first weighed and subsequently irradiated at the Portuguese Research Reactor. Results showed that PM(10) concentrations in Cape Verde markedly exceeded the health-based air quality standards defined by the European Union (EU), World Health Organization (WHO), and U.S. Environmental Protection Agency (EPA), in part due to the influence of Sahara dust transport. The PM(10) composition was characterized essentially by high concentrations of elements originating from the soil (K, Sm, Co, Fe, Sc, Rb, Cr, Ce, and Ba) and sea (Na), and low concentrations of anthropogenic elements (As, Zn, and Sb). In addition, the high concentrations of PM measured in Cape Verde suggest that health of the population may be less affected compared with other sites where PM(10) concentrations are lower but more enriched with toxic elements.

  18. How hazardous is the Sahara Desert crossing for migratory birds? Indications from satellite tracking of raptors

    2010-01-01

    We investigated the risk associated with crossing the Sahara Desert for migrating birds by evaluating more than 90 journeys across this desert by four species of raptors (osprey Pandion haliaetus, honey buzzard Pernis apivorus, marsh harrier Circus aeruginosus and Eurasian hobby Falco subbuteo) recorded by satellite telemetry. Forty per cent of the crossings included events of aberrant behaviours, such as abrupt course changes, slow travel speeds, interruptions, aborted crossings followed by retreats from the desert and failed crossings due to death, indicating difficulties for the migrants. The mortality during the Sahara crossing was 31 per cent per crossing attempt for juveniles (first autumn migration), compared with only 2 per cent for adults (autumn and spring combined). Mortality associated with the Sahara passage made up a substantial fraction (up to about half for juveniles) of the total annual mortality, demonstrating that this passage has a profound influence on survival and fitness of migrants. Aberrant behaviours resulted in late arrival at the breeding grounds and an increased probability of breeding failure (carry-over effects). This study also demonstrates that satellite tracking can be a powerful method to reveal when and where birds are exposed to enhanced risk and mortality during their annual cycles. PMID:19955169

    2000-01-01

    Full Text Available While there is wide agreement that virtual communities - and other phenomena utilizing CMC technologies - have the capability to provide both interpersonal and informational interactions, the degree to which they can be seen as specifically information-oriented social spaces has been open to some question. Drawing upon theoretical and empirical work that emphasizes an environmental model of human information behaviour, a foundation is developed for a model of information exchange in virtual communities, and a typology of the varieties of information behaviour to be found in virtual communities is proposed. This typology will provide a mechanism for assessing the characteristics of virtual communities in terms of their support for information exchange, and has the potential to enhance our understanding of virtual communities as information environments.

  5. Sahara Dust Cloud

    Science.gov (United States)

    2005-01-01

    [figure removed for brevity, see original site] Dust Particles Click on the image for Quicktime movie from 7/15-7/24 A continent-sized cloud of hot air and dust originating from the Sahara Desert crossed the Atlantic Ocean and headed towards Florida and the Caribbean. A Saharan Air Layer, or SAL, forms when dry air and dust rise from Africa's west coast and ride the trade winds above the Atlantic Ocean. These dust clouds are not uncommon, especially during the months of July and August. They start when weather patterns called tropical waves pick up dust from the desert in North Africa, carry it a couple of miles into the atmosphere and drift westward. In a sequence of images created by data acquired by the Earth-orbiting Atmospheric Infrared Sounder ranging from July 15 through July 24, we see the distribution of the cloud in the atmosphere as it swirls off of Africa and heads across the ocean to the west. Using the unique silicate spectral signatures of dust in the thermal infrared, AIRS can detect the presence of dust in the atmosphere day or night. This detection works best if there are no clouds present on top of the dust; when clouds are present, they can interfere with the signal, making it much harder to detect dust as in the case of July 24, 2005. In the Quicktime movie, the scale at the bottom of the images shows +1 for dust definitely detected, and ranges down to -1 for no dust detected. The plots are averaged over a number of AIRS observations falling within grid boxes, and so it is possible to obtain fractional numbers. [figure removed for brevity, see original site] Total Water Vapor in the Atmosphere Around the Dust Cloud Click on the image for Quicktime movie The dust cloud is contained within a dry adiabatic layer which originates over the Sahara Desert.

    Water resources in Algeria are not distributed evenly inspace and time that engenders enormous difficulties for their mobilization. Water shortage is becoming a major problem. A number of regions already suffers from water deficiency and the others will soon follow. To solve this problem, the construction of new dams becomes indispensable. Through the hydrological studies and the exploitation of future dams, the evaluation of wateryield in sites of these structures is indispensable. At present, the calculation of the interannual runoff in absence of data for the not gauged watercourse is determined from empirical formulae established especially for the climatic and geographical conditions of Algeria. Unfortunately, all these formulas do not provide accurate results.Watersheds which were used in the study represent almost the entire surface of Northern Algeria whose number is 106 basins.The objective of the present study is to establish working tools, allowing the planners and the managers to determine the value of the interannual runoff of watershed for the climatic conditions of Algeria without going through the empirical formulae often used in the absence of measurable dataand leading to absurd errors.The calculation parameters for interannual runoff from the proposed model are standard meteorological data (air temperature, humidity and pluviometry), always available and periodically broadcastedby meteorological services and hydrology of Algeria. Runoff values calculated by the model are close to the values of measured runoff.The difference between them didnot exceed 15 to 20%. (author)

    As part of our inquiry into how youth development and 4-H programming can affect the development of social capital for youth and for the community, we engaged youth in ripple mapping. Based on this information, we provide a typology of participation structures in youth development activities and the expected bridging and bonding social capital outcomes for each type. This article outlines the key factors underlying the typology and discusses strategies for using the typology to expand the impact of youth development and 4-H programming on young people and communities. It also outlines potential implications for increasing opportunities for fostering social capital leading to a spiraling-up effect for youth, volunteers, and the community.

    2011-01-01

    Background Physical inactivity plays a central role in the age-related decline in muscle strength, an important component in the process leading to disability. Personality, a significant determinant of health behaviors including physical activity, could therefore impact muscle strength throughout adulthood and affect the rate of muscle strength decline with aging. Personality typologies combining “high neuroticism” (N≥55), “low extraversion” (Epersonality types. Facet analyses suggest an important role for the N components of depression and hostility. Physical activity level appears to partly explain some of these associations. Conclusion Findings provide support for the notion that the typological approach to personality may be useful in identifying specific personality types at risk of low muscle strength and offer the possibility for more targeted prevention and intervention programs.

  13. The value of dispatchability of CSP plants in the electricity systems of Morocco and Algeria

    International Nuclear Information System (INIS)

    Brand, Bernhard; Boudghene Stambouli, Amine; Zejli, Driss

    2012-01-01

    This paper examines the effects of an increased integration of concentrated solar power (CSP) into the conventional electricity systems of Morocco and Algeria. A cost-minimizing linear optimization tool was used to calculate the best CSP plant configuration for Morocco's coal-dominated power system as well as for Algeria, where flexible gas-fired power plants prevail. The results demonstrate that in both North African countries, storage-based CSP plants offer significant economic advantages over non-storage, low-dispatchable CSP configurations. However, in a generalized renewable integration scenario, where CSP has to compete with other renewable generation technologies, like wind or photovoltaic (PV) power, it was found that the cost advantages of dispatchability only justify CSP investments when a relatively high renewable penetration is targeted in the electricity mix. - Highlights: ► Market model to optimize CSP plant configuration in North African power systems. ► Value of storage-based CSP plants compared to non-dispatchable configurations: 28–55 €/MWh. ► Assessment of Morocco's and Algeria's renewable electricity targets until 2030. ► CSP becomes more competitive with intermittent technologies when high RES-E quota are targeted.

    1984-01-01

    Along southern border of the Hoggar (Algeria) Precambrian shield, Lower Palaeozoic sediments lie unconformably on weathered metamorphic rocks. Along the eastern border of the Tin Seririne basin some good examples of the weathered rocks underneath the unconformity are exposed. The palaeosurface is a peneplain with only minor topographical reliefs from one to a few metres high. The nature and intensity of the weathering process was controlled by the topography, and the existence of badly drained areas is particularly important. At one such area the Tahaggart uranium ore deposit was discovered. The uranium ore consists mainly of torbernite and autunite. The deposit is present in the weathered gneiss underneath the palaeosurface. Mineralogical and geochemical observations indicated that the ore deposit was formed during the period of weathering which was controlled by climatological and palaeotopographical factors. (author)

    Holistic depiction of time-trends in average mortality rates, and absolute and relative inequalities, is challenging. We outline a typology for situations with falling average mortality rates (m↓; e.g., cardiovascular disease), rates stable over time (m-; e.g., some cancers), and increasing average mortality rates (m↑; e.g., suicide in some contexts). If we consider inequality trends on both the absolute (a) and relative (r) scales, there are 13 possible combination of m, a, and r trends over time. They can be mapped to graphs with relative inequality (log relative index of inequality [RII]; r) on the y axis, log average mortality rate on the x axis (m), and absolute inequality (slope index of inequality; SII; a) as contour lines. We illustrate this by plotting adult mortality trends: (1) by household income from 1981 to 2011 for New Zealand, and (2) by education for European countries. Types range from the "best" m↓a↓r↓ (average, absolute, and relative inequalities all decreasing; southwest movement in graphs) to the "worst" m↑a↑r↑ (northeast). Mortality typologies in New Zealand (all-cause, cardiovascular disease, nonlung cancer, and unintentional injury) were all m↓r↑ (northwest), but variable with respect to absolute inequality. Most European typologies were m↓r↑ types (northwest; e.g., Finland), but with notable exceptions of m-a↑r↑ (north; e.g., Hungary) and "best" or southwest m↓a↓r↓ for Spain (Barcelona) females. Our typology and corresponding graphs provide a convenient way to summarize and understand past trends in inequalities in mortality, and hold potential for projecting future trends and target setting.

  19. Greening of the Sahara - a paleo perspective on the history of water in the Middle East and North Africa

    Bar-Matthews, M.

    2012-04-01

    The Middle-East, mostly at its southern edge together with North Africa, the northern edge of the Sahara Desert, are located at the boundary between high- to-mid latitude and tropical-subtropical climate systems. The geographical duality of desert adjacent to Mediterranean-type climate regions played and still plays a major role on the water availability. Thanks to the number of important paleoclimate studies that been made on accurate dating of cave speleothems in Southern Arabia and Oman (Fleitmann et al., 2011) and in the northeast Sahara, the Negev Desert Israel (Vaks et al., 2010) and the study of sapropels in Eastern and central Mediterranean (Almogi-Labin et al., 2009; Osborne et al, 2008), it is clear that the region was graced with water during peak interglacials when the African monsoon and westerly storm/rainfall systems intensified. Northward penetration of the Inter Tropical Convergence Zone over the Arabian and African continents resulted in increased discharge of the Nile River and rivers that emerged from central Sahara into the Eastern Mediterranean Sea. Correspondingly, enhanced westerly wind activity led to an increase in rainfall from Atlantic-Mediterranean sources over the entire Mediterranean basin, which even penetrated south into the north-east corner of the Sahara Desert. The Saharo-Arabian Desert became narrower and climatic "windows" opened for the dispersal of hominids and animals out of the African continent at 250-239, 210-193, 138-120, 108-98, 87-84 and 10-6.5 ka BP, with severe dry conditions in between. Greening of the Sahara Desert at these intervals is supported also by various marine and terrestrial records, such as corals, lakes, tufa deposits and archeological findings. Dry conditions prevailed in the Sahara desert during glacials. This is in contrast to the climatic conditions in the Eastern Mediterranean coastal region and the Jordan Rift Valley (Bar-Matthews et al., 2003; Lisker et al., 2010), where water was available for

    In Algeria, visceral leishmaniasis (VL) is due to Leishmania (L.) infantum, while three cutaneous forms (CL) are caused by Leishmania major, Leishmania tropica and Leishmania infantum. In this study, the use of Giemsa-stained slides was evaluated with two PCR techniques, in Eastern Algeria. A total of 136 samples corresponding to 100 CL smears (skin scrapings) and 36 VL slides (bone marrow aspirates) collected from 2008 to 2014 were tested. Upon DNA extraction, two PCRs were used to amplify the ribosomal Internal Transcribed Spacer 1 (ITS1) and mini-exon genes. Amplified products were digested (PCR-RFLP) and profiles analyzed for Leishmania species identification. A statistical analysis was also performed. ITS1-PCR was found significantly more sensitive than mini-exon-PCR (77.95% positives vs. 67.65%; p = 0.001). Comparison of PCR positivity showed statistically significant differences between old and recently prepared slides suggesting a better use of recent slides in PCR analyses. For species identification, PCR-restriction fragment length polymorphism (RFLP) results of ITS1 and mini-exon were concordant. L. infantum was identified from VL cases and L. infantum, L. major, and L. tropica from CL ones. According to geographical origin, L. infantum was found in North-Eastern provinces, while L. major was distributed from the North to the Center-East of Algeria. Interestingly, two L. tropica samples were identified in Annaba, located far North-East Algeria. Distribution of leishmaniasis in Eastern parts of Algeria, besides finding of L. tropica in the far North, is in this study described for the first time using molecular tools, thus confirming the usefulness of slides for PCR identification of Leishmania parasites in retrospective epidemiological investigations.

  3. [The Concept of Typology in Psychiatry in the Context of Historical Contributions of Max Weber and Karl Jaspers].

    Jäger, M; Becker, T; Wigand, M E

    2016-08-01

    Against the background of Max Weber's and Karl Jaspers' outstanding historical contributions to the conceptual development of different typologies, the importance of a psychiatric typology is examined. The term "ideal type" was introduced into social science by Weber as an analytical construct to describe and classify cultural phenomena. This concept was adopted for the psychiatric context by Jaspers who proposed to establish a typological system in the field of psychotic disturbances without an organic correlate. He emphasized the importance of the course of psychopathological symptoms for such a typological system. The concept of typology can be regarded as a promising heuristic approach in psychiatry, providing a classification system for complex psychopathological symptoms. Even though several historic typologies exist in psychopathology, their usefulness in the fields of therapy and prognosis needs to be critically assessed. Also, new typologies will have to be developed, taking into account neurobiological knowledge now available. © Georg Thieme Verlag KG Stuttgart · New York.

  4. A broadened typology on energy and security

    International Nuclear Information System (INIS)

    Johansson, Bengt

    2013-01-01

    A broadened typology describing the interconnection between energy and security is developed in this paper, with the aim of improving understanding of the relationship between energy and security by applying different research and policy perspectives. One approach involves studying energy as an object exposed to security threats, using concepts such as security of supply or security of demand. Another approach involves studying the role of the energy system as the subject in generating or enhancing insecurity. The latter approach includes studying the conflict-generating potential inherent in the economic value of energy, the risk of accidents and antagonistic attacks to energy infrastructure and the security risks related to the negative environmental impact of the energy system. In order to make a comprehensive analysis of the security consequences of proposed energy policies or strategies, all these aspects should be taken into account to varying degrees. The typology proposed here could be a valuable tool for ensuring that all security aspects have been considered. - Highlights: • The paper presents a broadened typology of energy and security, useful for policy analysis. • The energy system can be an object for security threats and as a subject generating or contributing to insecurity. • Energy as an object for security threats includes the concepts of security of supply and security of demand. • The economic value of energy can contribute to insecurity. • Technological and environmental risks of specific energy systems also provide potential threats to human security

  5. [Essentialism and typological thinking in biological systematics].

    Vasil'eva, L N

    2003-01-01

    In biological literature, essentialism and typological thinking are believed to be incompatible with evolutionary ideas. At present, the same considerations underlay the claims to abandon the Linnaean hierarchy, or the fundamental classificatory structure rooted in essentialism. This paper suggests to reconsider the negative views of Plato's typology and Aristotle's essentialism following the narrow interpretations that have nothing to do with the classification of living beings. Plato's theory of 'ideas' (or 'forms') is the basis of classificatory theory; it provided such concepts as 'species', 'genus', 'essence', 'dichotomous division' but the development of this theory in the framework of moral and esthetic values could not be beneficial to biology. Aristotle's essentialism is more complicated and exists in two forms; one of these, or classificatory essentialism, is a modification of Plato's typology; another one, or organismal essentialism, represents the shift of 'essence' from the world of relations between objects to the realm of particular things, where the concept of essence lost its basic meaning. It is senseless to look for unreal 'type of an organism' ('essence of a thing') but precisely this kind of essentialism is attractive for biologists and philosophers. Organismal essentialism is the underlying basis of so-called 'individuality thesis' that is used as a weapon against classificatory essentialism. The same thesis is associated with an extensional vision of taxa that also explains the criticism of Linnaean hierarchy, while the latter is the intentional structure and the first tool suggested for the rank coordination of many unequal taxa.

    2008-11-01

    Burglary is a serious, costly, and prevalent crime but prior typologies of burglars are mostly speculative and based on qualitative data. Using a sample of 456 adult career criminals, the current study used latent profile analysis to construct a methodologically rigorous quantitative typology. Four classes of burglars emerged: young versatile, vagrant, drug-oriented, and sexual predators. All groups demonstrated significant involvement in varied forms of crime, but the sexual predator group was the most violent and had the most serious criminal careers. Connections to the criminal career literature are offered and suggestions for further empirical study of offender typologies are discussed.

    2013-03-01

    Full Text Available The Sahara is more connected to the Mediterranean than often assumed and palynology, in particular, has provided evidence of past interrelations between the Mediterranean and the Sahara with pollen spectra from prehistoric Saharan deposits including Mediterranean taxa. In order to show human-environment relationships and populations’ strategies in response to changing environments, this paper presents a case study from the southern Sahara. This region offered a natural laboratory for the study of human/climate interaction as the range of environmental change extended from flood to drought, forcing people to cope with periodic environmental instability. When the tropical rainfall belt migrated northward, watertable outcropped in interdunal depressions and formed permanent lakes, which alternated with severe arid spells. As a case study, this paper presents the results of interdisciplinary investigations on climate changes, human adaptations and subsistence strategies at Gobero, in the southern Sahara of Niger. Gobero is a restricted archaeological area comprising 8 sites that surround the shores of a palaeolake. It was intermittently occupied between about 9500 cal years BP and 4500 BP. Due to alternating environmental conditions it could only be occupied at the beginning and at the end of the most humid periods.

    Silica is gaining increasing importance as it is the base for the production of pure silicon, for which several applications are under development in the electronic and solar energy sectors. The aim of this study is to characterize the sand taken from the Western Erg of Algeria to determine the percentage of silicon it contains. Characterization was done through physical analysis to determine the granulometry of the sand. A chemical analysis was next performed, using diffraction of X-rays and a scanning electron microscope to determine the chemical composition of the sand. Results showed that the sand is mainly made of quartz in the form of rounded and subbarrondis grains and that silicon is prevalent, accounting for 98% of the composition. This study demonstrated that sand from the Western Erg of Algeria is rich in silicon and could be used for silicon production.

    Millions of people worldwide are affected by dramatic social change (DSC). While sociological theory aims to understand its precipitants, the psychological consequences remain poorly understood. A large-scale literature review pointed to the desperate need for a typology of social change that might guide theory and research toward a better understanding of the psychology of social change. Over 5,000 abstracts from peer-reviewed articles were assessed from sociological and psychological publications. Based on stringent inclusion criteria, a final 325 articles were used to construct a novel, multi-level typology designed to conceptualize and categorize social change in terms of its psychological threat to psychological well-being. The typology of social change includes four social contexts: Stability, Inertia, Incremental Social Change and, finally, DSC. Four characteristics of DSC were further identified: the pace of social change, rupture to the social structure, rupture to the normative structure, and the level of threat to one's cultural identity. A theoretical model that links the characteristics of social change together and with the social contexts is also suggested. The typology of social change as well as our theoretical proposition may serve as a foundation for future investigations and increase our understanding of the psychologically adaptive mechanisms used in the wake of DSC.

    This study attempted to apply age at onset typology in ICD-10 diagnosed opioid dependence. The sample comprised 80 men seeking treatment at an addiction clinic. The measures included socio-demographic and clinical profile, Severity of Opioid Dependence Questionnaire, Modified Sensation Seeking Scale, Multiphasic Personality Questionnaire (MPQ) and Family History Assessment Module. A cut-off age of 20/21 years for an early-onset late-onset typology of opioid dependence was obtained using two methods - the modal age at onset method and one-third sample by age at onset method. The early onset group showed significant differences in terms of it being more often younger, urban, unmarried, wage earning or students, using oral opioids (not heroin or injectables), showing higher lifetime use and dependence of sedatives, earlier onset of use and dependence of sedatives and tobacco, and higher global psychopathology in terms of MPQ. The early onset group also showed statistically insignificant trends for lesser use and dependence of alcohol, higher severity of opioid dependence, more legal and less social complications, higher sensation seeking (except boredom susceptibility), and more frequent substance dependence in first degree relatives. The age at onset typology in opioid dependence appears to be feasible and having some similarities to similar typology in alcoholism.

  17. Spain and the Promotion of Governance in Algeria

    Directory of Open Access Journals (Sweden)

    Rafael Bustos García de Castro

    2007-12-01

    Full Text Available This article examines the reasons why Spain which possesses a consolidated democratic regime continues to promote democracy and even good governance in certain countries in such an uncertain, ambiguous manner. Recent events, such as the impact of international terrorism, have meant that there is an even more urgent need for providing democratic assistance to the neighbouring countries of the Maghreb region. In spite of its initial limitations and slants,the very concept of governance would represent a non-intrusive promotion of democracy. Nevertheless, Spain’s actors in the field of foreign policy and cooperation with development (as the case of Algeria illustrates perfectly have been clearly reluctant to commit themselves to this course of action. Spain’s patent energy dependence on Algeria (a fact that is often put forward as the main explanatory reason is called into question, with an argument based not only on the evidence of Spanish action in other countries in regions (such as Tunisia and Latin America, but also in an analysis of the discourses and instruments of Spanish foreign policy. As an alternative explanation, it is suggested that practices that have long been used in Spain’s “Arab” foreign policy, the pending reform of the external service, the Europeisation of external action and the “second-player syndrome” (i.e. second to France, provide a better explanation ofSpain’s ambiguousness and of its slow abandonment of policies that favour the status quo.

    Background Investigators have proposed the diagnostic value of a generalized subtype of specific phobia, with classification based upon the number of phobic fears. However, current and future typologies of specific phobia classify the condition by the nature of phobic fears. This study investigated the clinical relevance of these alternative typologies by: (1) presenting the prevalence and correlates of specific phobia separately by the number and nature of phobia types; and (2) examining the clinical and psychiatric correlates of specific phobia according to these alternative typologies. Methods The National Comorbidity Survey Replication-Adolescent Supplement (NCS-A) is a nationally representative face-to-face survey of 10,123 adolescents aged 13–18 years in the continental United States. Results Most adolescents with specific phobia met criteria for more than one type of phobia in their lifetime, however rates were fairly similar across DSM-IV/5 subtypes. Sex differences were consistent across DSM-IV/5 subtypes, but varied by the number of phobic types, with a female predominance observed among those with multiple types of phobias. Adolescents with multiple types of phobias exhibited an early age of onset, elevated severity and impairment, and among the highest rates of other psychiatric disorders. However, certain DSM-IV/5 subtypes (i.e. blood-injection-injury and situational) were also uniquely associated with severity and psychiatric comorbidity. Conclusions Results indicate that both quantitative and DSM-IV/5 typologies of specific phobia demonstrate diagnostic value. Moreover, in addition to certain DSM-IV/5 subtypes, a generalized subtype based on the number of phobias may also characterize youth who are at greatest risk for future difficulties. PMID:23108894

    It is widely accepted that dopamine and serotonin (5-HT) neurotransmission can be critically involved in the development of alcohol abuse and alcohol dependence. Lesch's typology of alcoholism has been gaining increasing popularity as it qualitatively differentiates patients into different treatment response subgroups. The aim of the present study was to evaluate a possible genetic background of Lesch's typology with special emphasis placed on dopamine- and serotonin-related genes. 122 alcoholics (the mean age: 35+/-9 years) were investigated. According to Lesch's typology, 58 patients were of type I, 36 patients of type II, 11 patients of type III, and 17 patients of type IV. Alcohol drinking and family history was assessed by means of a structured interview, based on the Semi-Structured Assessment for the Genetics of Alcoholism. 150 control subjects without psychiatric disorders were also recruited. The control group was ethnically-, age- and gender-matched to the patients. The DRD2 TaqIA, exon 8, and promoter -141C ins/del polymorphisms as well as COMT Val158Met, 5HTT 44 bp del in promoter, and DAT 40 bp VNTR polymorphisms were detected by means of PCR. No significant differences were observed when the whole group of alcoholics and the controls were compared. Similarly, there were no differences between either the Lesch type I or type II alcoholics and the control subjects. No significant differences were observed between type I and type II alcoholics. Alleles frequencies were not calculated for the Lesch type III and type IV alcoholics since the number of patients was too small. The present results argue against any major role of the investigated polymorphisms in either Lesch type I or type II alcoholism. More comprehensive studies are needed to define the role of the investigated polymorphisms in Lesch type III and type IV alcoholism.

    Full Text Available Avian urolithiasis is one of the major causes of mortality in poultry. However, in Algeria this condition has never been described. An outbreak of avian urolithiasis was observed on a large commercial egg complex in the department of Chlef (West of Algeria. The clinical features of this condition are to be described. Mortality associated to urolithiasis started at the onset of egg production, estimated to 0.7 % per week. Urolithiasis induced an egg drop estimated to 12%. Dead and live layers were both necropsied and examined for kidney lesions. Most of the birds examined presented enlarged ureters, renal atrophy and visceral gout deposition.

    Calibration and validation are crucial steps in the production of the catastrophe models for the insurance industry in order to assure the model's reliability and to quantify its uncertainty. Calibration is needed in all components of model development including hazard and vulnerability. Validation is required to ensure that the losses calculated by the model match those observed in past events and which could happen in future. Impact Forecasting, the catastrophe modelling development centre of excellence within Aon Benfield, has recently launched its earthquake model for Algeria as a part of the earthquake model for the Maghreb region. The earthquake model went through a detailed calibration process including: (1) the seismic intensity attenuation model by use of macroseismic observations and maps from past earthquakes in Algeria; (2) calculation of the country-specific vulnerability modifiers by use of past damage observations in the country. The use of Benouar, 1994 ground motion prediction relationship was proven as the most appropriate for our model. Calculation of the regional vulnerability modifiers for the country led to 10% to 40% larger vulnerability indexes for different building types compared to average European indexes. The country specific damage models also included aggregate damage models for residential, commercial and industrial properties considering the description of the buildings stock given by World Housing Encyclopaedia and the local rebuilding cost factors equal to 10% for damage grade 1, 20% for damage grade 2, 35% for damage grade 3, 75% for damage grade 4 and 100% for damage grade 5. The damage grades comply with the European Macroseismic Scale (EMS-1998). The model was validated by use of "as-if" historical scenario simulations of three past earthquake events in Algeria M6.8 2003 Boumerdes, M7.3 1980 El-Asnam and M7.3 1856 Djidjelli earthquake. The calculated return periods of the losses for client market portfolio align with the

    The purpose of this paper was to review the theoretical underpinnings, major concepts, and methods of the typological approach. It was argued that the typological approach offers a systematic, empirically rigorous and reliable way to synthesize the nomothetic variable-centered approach with the idiographic case-centered approach. Recent advances in cluster analysis validation make it a promising method for uncovering natural typologies. This paper also reviewed findings from personality and family studies that have revealed 3 prototypical personalities and parenting styles: Adjusted/Authoritative, Overcontrolled/Authoritarian, and Undercontrolled/Permissive. These prototypes are theorized to be synonymous with attractor basins in psychological state space. The connection between family types and personality structure as well as future directions of typological research were also discussed.

    Purpose. Political, national, religious, and other motivations have led the media and even scientists to errantly accept extreme longevity claims prima facie. We describe various causes of false claims of extraordinary longevity. Design and Methods. American Social Security Death Index files for the period 1980-2009 were queried for individuals with birth and death dates yielding ages 110+ years of age. Frequency was compared to a list of age-validated supercentenarians maintained by the Gerontology Research Group who died during the same time period. Age claims of 110+ years and the age validation experiences of the authors facilitated a list of typologies of false age claims. Results. Invalid age claim rates increase with age from 65% at age 110-111 to 98% by age 115 to 100% for 120+ years. Eleven typologies of false claims were: Religious Authority Myth, Village Elder Myth, Fountain of Youth Myth (substance), Shangri-La Myth (geographic), Nationalist Pride, Spiritual Practice, Familial Longevity, Individual and/or Family Notoriety, Military Service, Administrative Entry Error, and Pension-Social Entitlement Fraud. Conclusions. Understanding various causes of false extreme age claims is important for placing current, past, and future extreme longevity claims in context and for providing a necessary level of skepticism.

    Full Text Available Aim/Purpose: This study aims to develop a descriptive typology to better identify leadership toward creativity in virtual work in different types of companies. Background: The study empirically explores how leadership toward creativity occurs in virtual work and uses the theoretical lenses of creativity-conducive leadership and heterarchy to generate a typology. Methodology\t: A multiple qualitative case study design, interpretivist approach, and abductive analysis are applied. Data is collected by interviewing 21 leaders and employees face-to-face in four companies in the ICT sector and one business advisor company. Contribution: The empirical evidence of this study enriches the understanding of leadership toward creativity in virtual work and contributes to the limited empirical knowledge on leadership that stimulates a virtual workforce to achieve creativity. Findings: The four different types of companies in the typology utilize various transitions toward leadership creativity in virtual work. The trend in leadership in the existing virtually networked business environment is toward the “collective mind” company, which is characterized by shared values, meaningful work, collective intelligence, conscious reflection, transparency, coaching, empowering leadership by example, effective multichannel interaction, and assertiveness. The findings empirically support applying a heterarchy perspective to lead a virtual workforce toward creativity and promote leaders who are genuinely interested in people, their development, collaboration, and technology. Recommendations for Practitioners: The typology helps professionals realize the need to develop leadership, communication, interaction, learning, and growth to foster creative interaction and improve productivity and competitiveness. Recommendation for Researchers: This study enables researchers to more rigorously and creatively conceptualize the conditions and relationships in leadership that

  18. The black-and-white world: Towards the history of dual typologies of nationalism

    2005-01-01

    Full Text Available Attempts at formulating a dichotomous classification of nations and nationalisms have proliferated in the relevant literature over a long period of time. In this study some of the most influential instances of dual typologies of nationalisms are selected for interpretation and analysis. The examples include Renan's under­standing of differences between the "French" and the "German" concepts of nation; Kohn's distinction between "eastern" and "western" nationalisms; a revision of Kohn's dichotomy suggested by J. Plamenatz; and a more recent version of dual typology propounded by L. Greenfield. By reconstructing the views of the selected theorists of nationalism, at the basis of all these typologies a dichotomous division into "civic" and "ethnic" nationalism is identified. Critical objections to this fundamental dual division are articulated at two levels. At the first, historical level, a socio-political contextualization of dual typologies points to their practical, political-ideological purposes. At the second, conceptual level, and drawing on the ideas of R. Brubaker, the author discusses analytical and normative weaknesses of the usual distinction between "civic" and "ethnic" nationalism.

    Full Text Available Abstract There is an ongoing global movement for the entrenchment of occupational mental health as an integral part of occupational health and safety schemes. Aside from being a fundamental human right issue, this move has been demonstrated to be of cost-benefit in terms of workplace productivity and general economic growth. Despite being among the regions most prone to the human and economic repercussions of work-related mental health problems by reason of her socio-economic circumstance; sub-Sahara Africa is yet to fully plug into this movement. With a view to make recommendations on the ways forward for sub-Sahara Africa, this paper examines the current state of and the barriers to effective occupational mental health policy and practice in the region.

    In Algeria, previous studies investigated genotypes of Echinococcus granulosus sensu lato in animals and identified E. granulosus sensu stricto (s.s.) genotypes G1 and G3 whereas Echinococcus canadensis genotype G6 was only reported from dromedary cysts. Molecular data on human cystic echinococcosis (CE) were limited. We implemented a large genotyping study of hydatid cysts from humans and livestock animals to specify CE's molecular epidemiology and the genetic diversity in Algeria. Fifty-four human CE cysts from patients predominantly admitted in surgical units from Mustapha Hospital, Algiers, and 16 cysts from livestock animals gathered in two geographically distinct slaughterhouses, Tiaret and Tamanrasset, were collected. Molecular characterization was performed using sequencing of two mitochondrial genes, cytochrome c oxidase subunit I (COI) and NADH dehydrogenase subunit I (NDI). In humans, G1 of E. granulosus s.s. was the main genotype (90.7 %); four samples (7.4 %) were characterized as E. granulosus s.s. G3 and one cyst as E. canadensis G6 (1.8 %). This molecular confirmation of E. canadensis G6 human infection in Algeria was observed in a Tuareg female living in a desertic area in Tamanrasset. All cysts from sheep, cattle, and goat were identified as E. granulosus s.s. G1 and the two cysts originating from dromedary as E. canadensis G6. Twenty concatenated haplotypes (COI + NDI) were characterized. Among E. granulosus s.s., one haplotype (HL1) was highly predominant in both humans and animals cysts (71.6 %). This study revealed main occurrence of E. granulosus s.s. in humans and livestock animals, with description of a predominant shared haplotype corresponding to the main worldwide observed haplotype E.granulosus s.s. G1. E. canadensis G6 was limited to South Algeria, in dromedary as well as in human.

    In Algeria most of the urban waste water is dumped without treatment into the Sea. It is tremendously important to assess the consequences of organic matter rich sewage on marine ecosystem. In this study we investigated the effects of industrial and urban sewage on the dissolved oxygen (O2), chemical oxygen demand (COD), biochemical oxygen demands (BOD5), pH, salinity, electrical conductivity (EC), Metal element (Hg, Pb, Cu, Ni, Cr, Cd), petroleum hydrocarbons (HC), oil and grease (OG) in Bay of Oran, Algeria. A ten-year follow-up research showed that the concentrations of oil and grease released into the bionetwork are of higher ecological impact and this needs to be given the desired consideration. Information on bathing water quality revealed that the most beaches in Oran are under the national environmental standard limit. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Argasid ticks (soft ticks) are blood-feeding arthropods that can parasitize rodents, birds, humans, livestock and companion animals. Ticks of the Ornithodoros genus are known to be vectors of relapsing fever borreliosis in humans. In Algeria, little is known about relapsing fever borreliosis and other bacterial pathogens transmitted by argasid ticks. Between May 2013 and October 2015, we investigated the presence of soft ticks in 20 rodent burrows, 10 yellow-legged gull (Larus michahellis) nests and animal shelters in six locations in two different bioclimatic zones in Algeria. Six species of argasid ticks were identified morphologically and through 16S rRNA gene sequencing. The presence and prevalence of Borrelia spp., Bartonella spp., Rickettsia spp. and Anaplasmataceae was assessed by qPCR template assays in each specimen. All qPCR-positive samples were confirmed by standard PCR, followed by sequencing the amplified fragments. Two Borrelia species were identified: Borrelia hispanica in Ornithodoros occidentalis in Mostaganem, and Borrelia cf. turicatae in Carios capensis in Algiers. One new Bartonella genotype and one new Anaplasmataceae genotype were also identified in Argas persicus. The present study highlights the presence of relapsing fever borreliosis agents, although this disease is rarely diagnosed in Algeria. Other bacteria of unknown pathogenicity detected in argasid ticks which may bite humans deserve further investigation.

In this study, we examined the composition and distribution of the invertebrate communities in the phreatic zone of the Tafna aquifer (N-W Algeria. Twelve wells close to the Tafna wadi, ranging between 120 and 1100 m a.s.l., were studied from May 2005 to March 2006. Many specimens belonging to 37 taxa were collected, the most frequent taxa being Typhlocirolana sp., a stygobitic Gammaridae species, Cyclopidae and Ostracoda. Other crustacean species were relatively scarce, with discontinuous distribution, being present only in a few wells. The taxonomic richness and abundance of stygobitic crustacean communities were relatively constant over time. The spatial distribution of stygobionts was mainly related to the exchanges with surface water.

    2013-01-01

    This article adds to the growing body of knowledge in sport pedagogy and focuses specifically upon the intersection of gender and disability. Its purpose is twofold, to create a typology for examining good practice in sport pedagogy that is reflective and inclusive and raises awareness of the diverse needs of all participants in physical activity 'regardless' of gender and ability for all children. We acknowledge that access to physical activity, education and sport are complex and multifaceted, however, the main purpose of this paper is to raise awareness of 'diversity' by focusing specifically upon the role of gender and ability. Through an examination of gender and disability policies in official European Union (EU) policy documents and commercial examples of policy-in-practice we propose a typology for diversity and diversity management. A close look at EU level is instructive because national policies of the member countries vary a lot with respect to diversity issues but should be in accordance in the main areas. Such a reading enables the building of a typology of recommendations for how such policy can be rendered in sport pedagogy practice. We suggest six significant, but related principles that include (1) mainstreaming; (2) teaching and coaching sensitive to difference; (3) empowerment; (4) inclusion; (5) adaptation; and (6) inner differentiation. This holistic typology seeks to 'mainstream' issues of gender and disability policy by providing a set of principles that can be applied to a range of teaching and coaching settings.

  13. Research approach for forming a new typology of spatial planning theory

    Directory of Open Access Journals (Sweden)

    Bulajić Vladan

    2011-01-01

    Full Text Available What is being suggested in this paper is the research approach for the classification of theoretical contributions in the scientific domain of the spatial planning. Typology is a multidimensional classification, actually it is the framework for the understanding of the subject area, theory and practice, ideas and methodologies. The complex approach is needed to organize the complex and diverse domain of spatial planning theory, which has been shaped by different schools of thought and the influences of the related scientific disciplines. It has been suggested that the research approach becomes the bridge between two cultures, in other words it should be the synthesis of the qualitative and quantitative methods of the typology construction. With the analysis of the existing typologies, which are quantitatively derived, the chosen concepts will be improved and completed due to the computerized statistical analysis of the appropriate bibliometrical data. Moreover, the procedure in the opposite direction will be used, which also connects empiric types with their conceptual counterparts. With that approach, the main aim is to achieve the comprehensive classification scheme, which will take part of the platform for integration of the interdisciplinary approach in the spatial planning domain. That concept of the research belongs to the wider approach that has got the aim that with the scientific innovations and imaginations bring about the solving of the problems and challenges that the spatial planning faces with. The forming of the new typology is the first step in that direction.

    Longitudinal integrated clerkships (LICs) represent a model of the structural redesign of clinical education that is growing in the USA, Canada, Australia and South Africa. By contrast with time-limited traditional block rotations, medical students in LICs provide comprehensive care of patients and populations in continuing learning relationships over time and across disciplines and venues. The evidence base for LICs reveals transformational professional and workforce outcomes derived from a number of small institution-specific studies. This study is the first from an international collaborative formed to study the processes and outcomes of LICs across multiple institutions in different countries. It aims to establish a baseline reference typology to inform further research in this field. Data on all LIC and LIC-like programmes known to the members of the international Consortium of Longitudinal Integrated Clerkships were collected using a survey tool developed through a Delphi process and subsequently analysed. Data were collected from 54 programmes, 44 medical schools, seven countries and over 15 000 student-years of LIC-like curricula. Wide variation in programme length, student numbers, health care settings and principal supervision was found. Three distinct typological programme clusters were identified and named according to programme length and discipline coverage: Comprehensive LICs; Blended LICs, and LIC-like Amalgamative Clerkships. Two major approaches emerged in terms of the sizes of communities and types of clinical supervision. These referred to programmes based in smaller communities with mainly family physicians or general practitioners as clinical supervisors, and those in more urban settings in which subspecialists were more prevalent. Three distinct LIC clusters are classified. These provide a foundational reference point for future studies on the processes and outcomes of LICs.

    Directory of Open Access Journals (Sweden)

    Tom J Coulthard

    Full Text Available Human migration north through Africa is contentious. This paper uses a novel palaeohydrological and hydraulic modelling approach to test the hypothesis that under wetter climates c.100,000 years ago major river systems ran north across the Sahara to the Mediterranean, creating viable migration routes. We confirm that three of these now buried palaeo river systems could have been active at the key time of human migration across the Sahara. Unexpectedly, it is the most western of these three rivers, the Irharhar river, that represents the most likely route for human migration. The Irharhar river flows directly south to north, uniquely linking the mountain areas experiencing monsoon climates at these times to temperate Mediterranean environments where food and resources would have been abundant. The findings have major implications for our understanding of how humans migrated north through Africa, for the first time providing a quantitative perspective on the probabilities that these routes were viable for human habitation at these times.

    In order to document medicinal uses of plants in the northeastern of Algeria, preserve traditional heritage and highlighted the risks of excessive human exploitation on flora and biodiversity of the region, an inventory of medicinal species existed in the traditional pharmacopoeia in Skikda region (north-east of Algeria) was made. The survey was carried out during the year (2015-2016), through face to face interviews, using pre-prepared questionnaire. The form contains: sociodemorgaphic profile of each respondent (sex, age, educational level and monthly income), local name of medicinal species used, uses, used parts and methods of preparations. A total of 90 species belonging to 42 botanical families, were listed. The analysis of the obtained results showed that the frequency of use of medicinal plants is related to the age, sex, educational level and monthly income of our respondents. It was recorded that the majority of remedies are prepared in the form of a decoctate from the leaves of the different species, in order to treat a wide range of diseases especially those of the digestive tract. Local population has a rich indigenous knowledge, but is always stays not adequately documented. It should be noted that some listed species are suffering from surexploitation which can subjects to the disappearance of the most vulnerable species. It will be urgent and essential to adopt a sustainable management strategy to avoid the degradation of biodiversity of the region. Copyright © 2017 Elsevier GmbH. All rights reserved.

    Full Text Available The purpose of the article is to develop a typology of techniques for motivation of personnel at mechanical engineering enterprises providing for systematization of their forms on the basis of a number of the existing features and identified new ones, which are justified by the requirements of today. There has been proved the fragmentary character of developments in this area making it impossible to form basic prerequisites for studying the concept. It has been found that certain features of the typology of methods for motivating employees may also be signs of a typology of techniques for motivation of personnel at enterprises of mechanical engineering industry. Among the current signs of a typology of techniques for motivation of personnel at mechanical engineering enterprises it is proposed to use the following ones: the nature of the impact; results obtained, object of the impact; direction; nature of the objectives; scope of the anticipated changes in the existing motivation system; nature of the needs, at which the techniques are directed. In addition, expediency of introducing new features of the typology, namely: the novelty level (classic and innovative motivation techniques, level of individualization (individual and standard; level of formalization (formalized at the high, medium and low level, source of the need for formation and implementation (the techniques, which necessity is specified by the enterprise, and the techniques, which necessity is specified by the business environment, origin («field» and «office» ones. These results allow forming a holistic view of the diversity of techniques for motivation of personnel at mechanical engineering enterprises as well as reasonable choosing among them their individual types at improving the motivation system. Prospects for further research in this direction should be allocation and systematization of the factors influencing the choice of one or another technique for motivation of

    This study presents an integrative typology of personality assessment for aggression. In this typology, self-report and conditional reasoning (L. R. James, 1998) methodologies are used to assess 2 separate, yet often congruent, components of aggressive personalities. Specifically, self-report is used to assess explicit components of aggressive tendencies, such as self-perceived aggression, whereas conditional reasoning is used to assess implicit components, in particular, the unconscious biases in reasoning that are used to justify aggressive acts. These 2 separate components are then integrated to form a new theoretical typology of personality assessment for aggression. Empirical tests of the typology were subsequently conducted using data gathered across 3 samples in laboratory and field settings and reveal that explicit and implicit components of aggression can interact in the prediction of counterproductive, deviant, and prosocial behaviors. These empirical tests also reveal that when either the self-report or conditional reasoning methodology is used in isolation, the resulting assessment of aggression may be incomplete. Implications for personnel selection, team composition, and executive coaching are discussed. 2007 APA, all rights reserved

The paper argues that the generalized version of the typology (Talmy 1991, 2000....... Constructions of the main information (MIC) and the supportive information (SIC), of varying degree of specificity, are the basic constituents of the typology. From this point of view, Germanic languages tend to map the main information (MI) onto a complex schematic construction and the supportive information...... (SI) onto a lexical (verbal) construction. Romance languages tend to map the MI onto the verb, while the SI may be mapped onto a complex schematic construction.

    Neuromyelitis optica (NMO) is a disabling inflammatory condition that targets astrocytes in the optic nerves and spinal cord. Recent advances led to the individualization of a set of conditions now referred as NMO spectrum disorder (NMOSD). To describe the prevalence and characteristics of NMO SD in north Algeria. The present study is a retrospective and descriptive work which took place in Nedir Mohamed teaching hospital, Tizi-Ouzou, Algeria. 938 Medical files of patients with CNS inflammatory demyelinating diseases were reviewed then patients with optic neuritis and/or myelitis were preselected. Patients who met the 2015 neuromyelitis optica spectrum disorders criteria were selected and analyzed 08 Patients (3.4%) met the 2015 criteria for neuromyelitis optica spectrum disorders, 3/8 (37.5%) were positive to AQ4-IgG and 5/8 (62.5%) were negative. Mean age of onset was 29 years, female to male ratio was 3:1, cerebral MRI was normal in 75% of cases and longitudinally extensive transverse myelitis was present in 75% of cases. 37/232 Patients (15.9%) were considered at high risk of neuromyelitis optica spectrum disorders The present study suggests that the spectrum of NMO disorders is a rare entity among patients with optic nerve and spinal cord demyelinating lesions in north Algeria. However, the lack of accurate AQ4-IgG test certainly underestimates its real prevalence. Copyright © 2015 Elsevier B.V. All rights reserved.

    Typologies of IPV and parenting practices in mothers who experienced police-reported IPV remain surprisingly unexplored, in addition to how those typologies are linked with children's externalizing problems. Using data from 162 Portuguese mother-child dyads with a police or child protection services referral of IPV, this study aimed to: (a) identify IPV-parenting typologies; (b) test the associations between typologies and children's externalizing problems, and (c) examine the moderating effect of children's exposure to other forms of family violence in those associations. Using a person-centered approach, two IPV-parenting typologies were found: a spillover typology, with high levels of physical, psychological, and sexual violence and high levels of harsh and inconsistent parenting practices; and a compartmentalized typology, with high levels of physical, psychological, and sexual violence and lower ineffective parenting practices. Results also showed that externalizing symptoms (reported by mothers and teachers) were significantly lower in children of mothers in the compartmentalized typology compared to those in the spillover typology. Children's direct exposure to other forms of family violence moderated this association. Findings suggested that children with a high exposure to other forms of family violence showed the highest levels of externalizing problems when their mothers were classified into the spillover typology, and they exhibited the lowest levels of externalizing problems when their mothers were classified in the compartmentalized typology.

    Full Text Available Argasid ticks (soft ticks are blood-feeding arthropods that can parasitize rodents, birds, humans, livestock and companion animals. Ticks of the Ornithodoros genus are known to be vectors of relapsing fever borreliosis in humans. In Algeria, little is known about relapsing fever borreliosis and other bacterial pathogens transmitted by argasid ticks.Between May 2013 and October 2015, we investigated the presence of soft ticks in 20 rodent burrows, 10 yellow-legged gull (Larus michahellis nests and animal shelters in six locations in two different bioclimatic zones in Algeria. Six species of argasid ticks were identified morphologically and through 16S rRNA gene sequencing. The presence and prevalence of Borrelia spp., Bartonella spp., Rickettsia spp. and Anaplasmataceae was assessed by qPCR template assays in each specimen. All qPCR-positive samples were confirmed by standard PCR, followed by sequencing the amplified fragments. Two Borrelia species were identified: Borrelia hispanica in Ornithodoros occidentalis in Mostaganem, and Borrelia cf. turicatae in Carios capensis in Algiers. One new Bartonella genotype and one new Anaplasmataceae genotype were also identified in Argas persicus.The present study highlights the presence of relapsing fever borreliosis agents, although this disease is rarely diagnosed in Algeria. Other bacteria of unknown pathogenicity detected in argasid ticks which may bite humans deserve further investigation.

    2009-11-01

    Full Text Available Persian master builders had introduced an architectural innovation which had an imperishable effect on dome architecture in the Middle East and Central Asia: surmounting a dome on squinches. This paper aims to provide a broader perspective of Persian domes as the most significant feature of Eastern domes in the Middle East. As opposed to previous general historic studies, this paper introduces a new analytical approach directed towards analysis of architectural concepts and stylistic attributes of Persian domes based on an epistemological premise of their space syntax. By analytic reviewing of examples, the paper addresses the origin of Persian domes, their formal morphological constitutions, and their typological forms based on the diversity of the external shell over the specific timeline, from the pre-Islamic era through the Qajar period in Iran. The study of the Persian dome’s characteristics can illustrate undiscovered information about the essences of developing dome constructions in the Middle East. It can also establish new design standards regarding the frameworks of domical building configurations to be used for creating typological diversity in dome design and to renew the morphological principles of the traditional dome compositions in contemporary architectural designs. Finally, the insights gained can inform conservation efforts on domical structures in the region and elsewhere.

    Full Text Available Online peer-production platforms facilitate the coordination of creative work and services. Generally considered as empowering participatory tools and a source of common good, they can also be, however, alienating instruments of digital labour. This paper proposes a typology of peer-production platforms, based on the centralization/decentralization levels of several of their design features. Between commons-based peer-production and crowdsourced, user-generated content “enclosed” by corporations, a wide range of models combine different social, political, technical and economic arrangements. This combined analysis of the level of (decentralization of platform features provides information on emancipation capabilities in a more granular way than a market-based qualification of platforms, based on the nature of ownership or business models only. The five selected features of the proposed typology are: ownership of means of production, technical architecture/design, social organization/governance of work patterns, ownership of the peer-produced resource, and value of the output.

    South of Algeria has these last years increasing water demand associated with rapid urban development and expansion in the irrigated land have led to over-exploitation of groundwater resources, consequently, it caused a degradation of the groundwater quality by increasing its salinity. In arid areas of Algeria with a shortage of pure water and endowed with an important solar potential, solar distillation is an important alternative for the potable water production. In this study, an attempt has been made to study a novel solar still by using a local material tested under climatic conditions of Adrar city. Experiments proprieties and performance of this solar still were carried out for a long time. The measurement of solar intensity, ambient temperature, water productivity, saline water temperature, glasses temperatures inside and outside, and the distilled water quality were studied. The results show that the daily productivity was varied from 4.04 to 4.48 l/m²d. Local materials are very interesting to increase the productivity and to give a good quality of output water with a low cost. Also, the results show that the output water quality is using for drinking and in accordance with WHO standards guidelines.

    The obsidian industry of Classic period Tikal, Guatemala, is discussed with regard to geological source determinations and behavioral typology. The potential of these two approaches for cultural reconstruction is greatly extended when they can supplement each other. Recent source determinations of obsidian artifacts from Tikal indicate (1) a behavioral link between locally-produced prismatic blades of Highland Guatemalan stone and ceremonial incised obsidians and eccentrics, and (2) a Central Mexican origin for a seemingly large portion of Tikal's obsidian projectile points and knives. 25 references, 3 figures, 5 tables.

    The trade winds that blow along the Atlantic coast from Morocco to Senegal represent one of the the largest and most productive wind potentials available on earth. Because of the erratic nature of winds however, wind electricity cannot be integrated locally on any significant scale, unless mechanisms are developed for storing these intermittent renewable energies. Developing distributed wind energy solutions feeding into smaller electricity markets are essential for solving energy access issues and enabling the development of a local, viable renewable energy industry. These may be critical to address the region's economic challenges currently under pressure from Sub-Saharan migrant populations. Windelectrolysis for the production of hydrogen can be used in grid stabilization, as power storage, fuel or chemical feedstock in specific industries. The objective of the NATO SfP 'Sahara Trade Winds to Hydrogen' project is to support the region's universities through an applied research framework in partnership with industries where electrolysis applications are relevant. By powering two university campuses in Morocco and Mauritania with small grid connected wind turbines and 30 kW electrolyzers generating hydrogen for power back-up as part of ''green campus concepts'' we demonstrated that wind-electrolysis for the production of hydrogen could absorb larger quantities of cheap generated wind electricity in order to maximize renewable energy uptakes within the regions weaker grid infrastructures. Creating synergies with local industries to tap into a widely available renewable energy source opens new possibilities for end users such as utilities or mining industries when processing raw minerals, whose exports generates key incomes in regions most exposed to desertification and climate change issue.

    This paper is based on using DMSP-OLS data from satellites nighttime light observations to detect both sources of light emissions in Algeria from human settlement areas and gas flaring from oil-extraction and natural gas production. We used the time series of data from DMSP-OLS images to examine the spatial and temporal characteristics of urban development in 48 Algerian provinces from 1993 to 2012. A systematic nighttime light calibration method was used to improve the consistency and comparability of the DSMPOSL images and then a separation is made between light detected from human settlements and light detected from gas flaring in order to allow us to study human settlements without other light emissions and then assess the suitability of using DMSP data in southern Algeria and its ability to monitor gas flaring. Linear regression methods were developed to identify the dynamic change of nighttime light and estimated its growth directions at pixel level. This work is the first to use nighttime light observations to detect and monitor the growth of human settlements in North Africa. In this study, we made use of DMSP-OLS data as a return ticket to the years of crises and we found the most affected provinces during that period. The DMSP-OLS data proved to be an index of growth in the economy during the period of stability in Algeria expressed by positive dynamic changes in the lighted area in all Algerian provinces. We used NTL data as an alternative to annual growth indexes for each province, which are unavailable, and its help as a monitoring system for socioeconomic parameters to fill the gap of data availability. We also proposed nighttime light remote sensing data as a useful tool to control and reduce CO2 emissions in Algeria's petroleum sector.

    Work schedules contribute substantially to the health and well-being of nurses. Too broad typologies are used in research that do not meet the current variety in work schedules. To develop a new typology for nurses' work schedules based on five requirements and to validate the typology. This study is based on a questionnaire returned by 498 nurses (response 51%) including questions regarding nurses' work schedule, socio-demographic, and family characteristics and their appraisal of the work schedule. Frequencies of the different schedules were computed to determine the typology. To validate the typology, differences between the types were tested with ANOVAs, Chi2 and Kruskal-Wallis tests. Five main types can be distinguished based on predetermined requirements and frequencies, namely: (1) fixed early shift, (2) rotating two shift pattern without night shift, (3) rotating three shift pattern, (4) fixed and rotating two shift pattern including night shift, and (5) fixed normal day or afternoon shifts. Nurses in these types of work schedule differed significantly with respect to hours worked, days off between shifts, age, education, years in the job, commuting time, contribution to household income, satisfaction with work schedule and work schedule control. Especially nurses with type 3 schedules differed from other types. A typology of five main types of work schedules is proposed. Content validity of the typology is sufficient and the new typology seems useful for research on work-related aspects of nursing.

    The relationships between circadian typology and several aspects related to mental health, such as satisfaction with life, emotional intelligence, perceived well-being and psychopathological symptomatology have been documented. However, their relationships with two psychological strengths such as resilience and optimism have not been examined yet. Therefore, the purpose of the present study was to explore whether circadian typology is related to both measures, taking into consideration the possible influence of sex. A sample of 1922 participants (978 men), aged between 18 and 60 yrs (30.08 ± 10.53) completed the reduced Morningness-Eveningness Questionnaire (rMEQ), the 10-item Connor-Davidson Resilience Scale (10-item CD-RISC) and the Life Orientation Test-Revised (LOT-R). Circadian typology was associated with different values in resilience (F(2,1915) = 45.89; p optimism (F(2,1915) = 37.74; p optimism scores while the lowest scores were shown by evening-type, exhibiting the neither-type subjects intermediate scores (p < 0.007, in all cases). These results suggest that evening-type subjects could display less capacity to face adversity and adapt positively, as well as less expectance of the occurrence of positive events compared to neither and morning-type individuals. In addition, these results provide new evidence that might improve our understanding about the relationships between circadian typology and psychological traits and disorders. Although future studies with longitudinal designs are needed, the obtained results emphasize that the evening-type could be a risk factor for the development of psychological problems and mental disorders, whereas the morning-type could be considered as a protective factor.

    Latent class analysis (LCA) offers a parsimonious way of classifying common typologies of psychiatric comorbidity. We used LCA to identify the nature and correlates of predominant typologies of Axis I and II disorders in a large and comprehensive population-based sample of U.S. adults. We analyzed data from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (2004-2005; n = 34,653), a population-based sample of U.S. adults. We derived latent classes based on all assessed Axis I and II disorders and examined the relationship between the identified Axis I classes and lifetime psychiatric disorders and suicide attempts, and physical and mental health-related quality of life. A four-class solution was optimal in characterizing predominant typologies of both Axis I and II disorders. For Axis I disorders, these included low psychopathology (n = 28,935, 84.0%), internalizing (n = 3693, 9.9%), externalizing (n = 1426, 4.5%), and high psychopathology (n = 599, 1.6%) classes. For Axis II disorders, these included no/low personality disorders (n = 31,265, 90.9%), obsessive/paranoid (n = 1635, 4.6%), borderline/dysregulated (n = 1319, 3.4%), and highly comorbid (n = 434, 1.1%) classes. Compared to the low psychopathology class, all other Axis I classes had significantly increased odds of mental disorders, elevated Axis II classes, suicide attempts and poorer quality of life, with the high psychopathology class having the overall highest rates of these correlates, with the exception of substance use disorders. Compared to the low psychopathology class, the internalizing and externalizing classes had increased rates of mood and anxiety disorders, and substance use disorders, respectively. Axis I and II psychopathology among U.S. adults may be best represented by four predominant typologies. Characterizing co-occurring patterns of psychopathology using person-based typologies represents a higher-order classification system that may be useful in clinical

    Full Text Available The paper considers the methodology and algorithm for the construction of typologies of regions in a two-dimensional space “level of development – dynamics of development” taking into account the quality of life, which is one of the most relevant competitiveness factors at the present stage of Russia’s development. The authors analyze the concept of “quality of life” and propose their own variant of the concept, on the basis of which they make a list of indicators for measuring and assessing the “quality of life” factor. In the implementation of the algorithm it is proposed to transform specific indicators, which assess the level and dynamics of the quality of life, into nonmetric numerical scores, normalized to the weighted average values of indicators for the Russian regions. The method of transformation of indicators into scores was tested on the example of the Northwestern Federal District regions, and the typologies in a two-dimensional space “level – dynamics” of the quality of life were made for 80 regions of Russia; the level of the quality of life was assessed according to official statistics for 2013, and the dynamics of the quality of life was assessed with the use of official statistics for 2011–2013. A detailed analysis is provided for each of the proposed typological groups and characteristics of this typology are highlighted. The proposed methodology and algorithm make it possible to compare and analyze not only the level and dynamics of development of different factors promoting competitive attractiveness, but also the interaction b etween the factors, for example, such as economy and the quality of life, economy and innovation, innovation and human resources, quality of life and innovation, etc. The typology provides a better understanding of advantages and disadvantages of both federal and local social policy for regional strategic development and helps justify the need and the focus of territorial

    Full Text Available Abstract Background Bovine Tuberculosis is prevalent in Algeria despite governmental attempts to control the disease. The objective of this study was to conduct, for the first time, molecular characterization of a population sample of Mycobacterium bovis strains isolated from slaughter cattle in Algeria. Between August and November 2007, 7250 animals were consecutively screened at the abattoirs of Algiers and Blida. In 260 animals, gross visible granulomatous lesions were detected and put into culture. Bacterial isolates were subsequently analysed by molecular methods. Results Altogether, 101 bacterial strains from 100 animals were subjected to molecular characterization. M. bovis was isolated from 88 animals. Other bacteria isolated included one strain of M. caprae, four Rhodococcus equi strains, three Non-tuberculous Mycobacteria (NTM and five strains of other bacterial species. The M. bovis strains isolated showed 22 different spoligotype patterns; four of them had not been previously reported. The majority of M. bovis strains (89% showed spoligotype patterns that were previously observed in strains from European cattle. Variable Number of Tandem Repeat (VNTR typing supported a link between M. bovis strains from Algeria and France. One spoligotype pattern has also been shown to be frequent in M. bovis strains from Mali although the VNTR pattern of the Algerian strains differed from the Malian strains. Conclusion M. bovis infections account for a high amount of granulomatous lesions detected in Algerian slaughter cattle during standard meat inspection at Algiers and Blida abattoir. Molecular typing results suggested a link between Algerian and European strains of M. bovis.

    2018-04-01

    This article explores moral distress among long-term care facility (LTCF) social workers by examining the relationships between moral distress and environmental and personal features. Based on these features, authors identified a typology of LTCF social workers and how they handle moral distress. Such a typology can assist in the identification of social workers who are in a particular need for assistance. Overall, 216 LTCF social workers took part in the study. A two-step cluster analysis was conducted to identify a typology of LTCF social workers based on features such as ethical environment, support in workplace, mastery, and resilience. The variance of the identified clusters and their associations with moral distress were examined, and four clusters of LTCF social workers were identified. The clusters varied from each other in relation to their personal and environmental features and in relation to their experience of moral distress. The article concludes with a discussion of the importance of developing programs for LTCF social workers that provide support and enhancement of personal resources and an adequate and ethical environment for practice.

    2016-06-01

    Full Text Available Previous studies on the Sasang typology have focused on the differential diagnosis of each Sasang type with type-specific pathophysiological symptoms (TSPS. The purpose of this study was to elucidate the latent physiological mechanism related to these clinical indicators. We searched six electronic databases for articles published from 1990 to 2015 using the Sasang typology-related keywords, and found and analyzed 35 such articles. The results were summarized into six TSPS categories: perspiration, temperature preference, sleep, defecation, urination, and susceptibility to stress. The Tae-Eum and So-Eum types showed contrasting features with TSPS, and the So-Yang type was in the middle. The Tae-Eum type has good digestive function, regular bowel movement and defecation, high sleep quality, and low susceptibility to stress and cold. The Tae-Eum type has relatively large volumes of sweat and feels fresh after sweating; however, the urine is highly concentrated. These clinical features might be related to the biopsychological traits of the Tae-Eum type, including a low trait anxiety level and high ponderal and body mass indices. This study used the autonomic reactivity hypothesis for explaining the pathophysiological predispositions in the Sasang typology. The Tae-Eum and So-Eum Sasang types have a low threshold in parasympathetic and sympathetic activation, respectively. This study provides a foundation for integrating traditional Korean personalized medicine and Western biomedicine.

    Full Text Available This article considers customer typology in fitness centres. The main aim of our survey is to state the basic segments of fitness customers and create their typology. A survey was conducted on a sample of 1004 respondents from 48 fitness centres. We used questionnaires and latent class analysis for the assessment and interpretation of data. The results of our research are as follows: we identified 6 segments of typical customers, of which three are male (we called them student, shark, mature and three are female (manager, hunter, and student. Each segment is influenced primarily by the age of customers, from which we can develop further characteristics, such as education, income, marital status, etc. Male segments use the main workout area above all, whilst female segments use a much wider range of services offered, for example group exercises, personal training, and cardio theatres.

  15. Gender and classifiers in concurrent systems: Refining the typology of nominal classification

    Directory of Open Access Journals (Sweden)

    Sebastian Fedden

    2017-04-01

    Full Text Available Some languages have both gender and classifiers, contrary to what was once believed possible. We use these interesting languages as a unique window onto nominal classification. They provide the impetus for a new typology, based on the degree of orthogonality of the semantic systems and the degree of difference of the forms realizing them. This nine-way typology integrates traditional gender, traditional classifiers and – importantly – the many recently attested phenomena lying between. Besides progress specifically in understanding nominal classification, our approach provides clarity on the wider theoretical issue of single versus concurrent featural systems.

  16. A typology of educationally focused medical simulation tools.

    Alinier, Guillaume

    2007-10-01

    The concept of simulation as an educational tool in healthcare is not a new idea but its use has really blossomed over the last few years. This enthusiasm is partly driven by an attempt to increase patient safety and also because the technology is becoming more affordable and advanced. Simulation is becoming more commonly used for initial training purposes as well as for continuing professional development, but people often have very different perceptions of the definition of the term simulation, especially in an educational context. This highlights the need for a clear classification of the technology available but also about the method and teaching approach employed. The aims of this paper are to discuss the current range of simulation approaches and propose a clear typology of simulation teaching aids. Commonly used simulation techniques have been identified and discussed in order to create a classification that reports simulation techniques, their usual mode of delivery, the skills they can address, the facilities required, their typical use, and their pros and cons. This paper presents a clear classification scheme of educational simulation tools and techniques with six different technological levels. They are respectively: written simulations, three-dimensional models, screen-based simulators, standardized patients, intermediate fidelity patient simulators, and interactive patient simulators. This typology allows the accurate description of the simulation technology and the teaching methods applied. Thus valid comparison of educational tools can be made as to their potential effectiveness and verisimilitude at different training stages. The proposed typology of simulation methodologies available for educational purposes provides a helpful guide for educators and participants which should help them to realise the potential learning outcomes at different technological simulation levels in relation to the training approach employed. It should also be a useful

    Polytraumatization classes based on trauma endorsement patterns relate to distinct clinical outcomes. Person-centered approaches robustly evaluate the nature, and construct validity of polytraumatization classes. Our review examined evidence for the nature and construct validity of lifespan polytraumatization typologies. In September 2016, we searched Pubmed, PSYCINFO, PSYC ARTICLES, Academic Search Complete, PILPTS, Web of Science, CINAHL, Medline, PsycEXTRA, and PBSC. Search terms included "latent profile," "latent class," "latent analysis," "person-centered," "polytrauma," "polyvictimization," "traumatization," "lifetime," "cooccurring," "complex," "typology," "multidimensional," "sequential," "multiple," "subtype," "(re)victimization," "cumulative," "maltreatment," "abuse," and "stressor." Inclusionary criteria included: peer-reviewed; latent class/latent profile analyses (LCA/LPA) of lifespan polytrauma classes; adult samples of size greater than 200; only trauma types as LCA/LPA indicators; mental health correlates of typologies; and individual-level trauma assessment. Of 1,397 articles, nine met inclusion criteria. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, research assistants completed a secondary reference search, and independently extracted data with standardized coding forms. Three-class (n = 5) or four-class (n = 4) solutions were found. Seven studies found a class characterized by higher trauma endorsement (high-trauma). All studies found a class characterized by lower trauma endorsement (low-trauma), and predominance of specific traumas (specific-trauma; e.g., childhood maltreatment). High-trauma versus low-trauma classes and specific-trauma versus low-trauma classes differed on mental health correlates. Evidence supports the prevalence of a high-trauma class experiencing poorer mental health, and the detrimental impact of aggregated interpersonal and other traumas. We highlight the clinical

    2002-09-01

    This study empirically identified types of African American families. Adolescents (N = 111) were assessed on family functioning. With cluster analytic methods, 3 types of families were identified. The cohesive-authoritative type was above average on parental education and income, averaged about 2 children, exhibited a high quality of family functioning and high self-esteem in adolescents. The conflictive-authoritarian type had average parental education and income, an average of 2.7 children, exhibited controlling and rigid discipline, and placed a high emphasis on achievement. The defensive-neglectful type was predominately headed by single mothers with below average education and income and averaged about 3 children. Such families displayed chaotic family processes, and adolescents tended to suffer from low self-esteem. The typology exhibited good reliability. The implications of the typology are discussed.

    We investigated the ecological differentiation of two members of the Culex pipiens complex, Cx. p. pipiens form pipiens and Cx. p. pipiens form molestus in three sites, El-Kala, M'Sila and Tinerkouk in Algeria. These two forms are the most widespread mosquito vectors in temperate regions exhibiting important behavioural and physiological differences. Nevertheless, this group of potential vectors has been poorly studied, particularly in North Africa. Ten larval populations of Cx. p. pipiens were sampled from various above- and underground habitats in three zones representing the three bioclimatic regions in Algeria. The reproduction characteristics were also investigated in the laboratory to define the rates of autogeny and stenogamy. Identification of Cx. p. pipiens members present in Algeria was achieved using a molecular analysis with the microsatellite CQ11 locus. We detected larvae of Cx. p. pipiens in all areas suggesting that the species is a ubiquitous mosquito well adapted to various environments. To our knowledge, this study provides the first molecular evidence of the presence of the Cx. p. pipiens form molestus and hybrids (molestus/pipiens) in Algeria with a high proportion of molestus form (48.3 %) in comparison with hybrids (36.8 %) and pipiens form (14.9 %). Some unexpected correlations between the proportion of forms pipiens, molestus and hybrids, and mosquito biological characteristics were observed suggesting some epigenetic effects controlling Cx. p. pipiens mating and reproduction. Consequences for pathogen transmission are discussed.

    An episode of acute equine respiratory infection was reported in western Algeria (Tiaret province) between February and March 2011, affecting a large population of horses. Nasal swabs (n=100) were taken from horses aged between 1 and 27 years, presenting with cough and mucopurulent nasal discharge. The prevalence of equine respiratory virus infections was examined using quantitative polymerase chain reaction (qPCR). One, or more, of four equine respiratory viruses were detected in the nasal swabs of 90 of 100 horses (90%) and the detection rate of equine herpesvirus type 1 (EHV-1), equine herpesvirus type 4 (EHV-4), equine herpesvirus type 2 (EHV-2) and equine herpesvirus type 5 (EHV-5) were 2%, 14%, 90% and 75%, respectively. Equine influenza virus and equine arteritis virus were not detected in any samples. Among the 90 infected horses, 70 were co-infected with EHV-2 and EHV-5 and 14 others were co-infected with EHV-4, EHV-2 and EHV-5. The present study shows a positivity rate of 97.3% for EHV-5 in young horses aged equine herpesviruses 1, 2, 4 and 5 are endemic in horse populations from Algeria as detected for the first time by qPCR.

    Argasid ticks are vectors of viral and bacterial agents that can infect humans and animals. In Africa, relapsing fever borreliae are neglected arthropod-borne pathogens that cause mild to deadly septicemia and miscarriage. It would be incredibly beneficial to be able to simultaneous detect and identify other pathogens transmitted by Argasid ticks. From 2012 to 2014, we conducted field surveys in 4 distinct areas of Algeria. We investigated the occurrence of soft ticks in rodent burrows and yellow-legged gull (Larus michahellis) nests in 10 study sites and collected 154 soft ticks. Molecular identification revealed the occurrence of two different soft tick genera and five species, including Carios capensis in yellow-legged gull nests and Ornithodoros occidentalis, Ornithodoros rupestris, Ornithodoros sonrai, Ornithodoros erraticus in rodent burrows. Rickettsial DNA was detected in 41/154, corresponding to a global detection rate of 26.6%. Sequences of the citrate synthase (gltA) gene suggest that this agent is a novel spotted fever group Rickettsia. For the first time in Algeria, we characterize a novel Rickettsia species by molecular means in soft ticks. Copyright © 2015 Institut Pasteur. Published by Elsevier Masson SAS. All rights reserved.

    There is a growing interest in resilience in internal crisis management and crisis communication. How an organization can build up resilience as a response to organisational crisis, at a time when the amount of crises seem only to increase, is more relevant than ever before. Nevertheless resilience...... is often perceived in the literature as something certain organisations have by definition, without further reflection on what it is that creates this resiliency. This article explores what it is that creates organisational resilience, and in view of the different understandings of the resilience...... phenomenon, develops a typology of resilience. Furthermore the resilience phenomenon is discussed against the definition of a crisis as a cosmological episode, and implications for future research is discussed and summarized....

  7. Inside the "African cattle complex": animal burials in the holocene central Sahara.

    Directory of Open Access Journals (Sweden)

    Savino di Lernia

    Full Text Available Cattle pastoralism is an important trait of African cultures. Ethnographic studies describe the central role played by domestic cattle within many societies, highlighting its social and ideological value well beyond its mere function as 'walking larder'. Historical depth of this African legacy has been repeatedly assessed in an archaeological perspective, mostly emphasizing a continental vision. Nevertheless, in-depth site-specific studies, with a few exceptions, are lacking. Despite the long tradition of a multi-disciplinary approach to the analysis of pastoral systems in Africa, rarely do early and middle Holocene archaeological contexts feature in the same area the combination of settlement, ceremonial and rock art features so as to be multi-dimensionally explored: the Messak plateau in the Libyan central Sahara represents an outstanding exception. Known for its rich Pleistocene occupation and abundant Holocene rock art, the region, through our research, has also shown to preserve the material evidence of a complex ritual dated to the Middle Pastoral (6080-5120 BP or 5200-3800 BC. This was centred on the frequent deposition in stone monuments of disarticulated animal remains, mostly cattle. Animal burials are known also from other African contexts, but regional extent of the phenomenon, state of preservation of monuments, and associated rock art make the Messak case unique. GIS analysis, excavation data, radiocarbon dating, zooarchaeological and isotopic (Sr, C, O analyses of animal remains, and botanical information are used to explore this highly formalized ritual and the lifeways of a pastoral community in the Holocene Sahara.

    On the 28th November 2002, Algeria's first enhanced micro satellite was launched into a 686 km low earth orbit onboard a Cosmos 3M rocket from Plesetsk. The spacecraft was designed, manufactured and launched as a technology transfer programme between the National Centre of Space Techniques (CNTS) Algeria and Surrey Satellite Technology Limited (SSTL) United Kingdom in the timescale of 18 months. This paper will describe the design and in orbit performance of the mission power system, stressing the decisions taken in order to meet the mission requirements within the 18 months, concept to launch programme. Most of the design and construction techniques used in the production of the Alsat-1 power system were based on SSTL heritage over the years. It will be shown how off the shelf components either for the generation or storage of the onboard energy can be applied successfully to such missions. (author)

    The aim of the present study was to screen for the presence of carbapenemase-producing Enterobacteriaceae (CPE) isolates from wild boars and Barbary macaques in Algeria. Fecal samples were collected from wild boars (n = 168) and Barbary macaques (n = 212), in Bejaia, Algeria, between September 2014 and April 2016. The isolates were identified and antimicrobial susceptibility was determined. Carbapenem resistance determinants were studied using PCR and sequencing, while clonal relatedness was performed using multilocus sequence typing (MLST). PCR was used to investigate certain virulence genes. Three CPE isolates from three different samples (1.8%) recovered from wild boars were identified as Escherichia coli (two isolates) and Klebsiella pneumoniae (one isolate). These isolates were resistant to amoxicillin, amoxicillin-clavulanate, tobramycin, ertapenem, and meropenem. The results of PCR and sequencing analysis showed that all three isolates produced the OXA-48 enzyme. The MLST showed that the two E. coli isolates were assigned to the same sequence type, ST635, and belonged to phylogroup A, whereas K. pneumoniae strain belonged to ST13. The K. pneumoniae strain was positive for multiple virulence factors, whereas no virulence determinants were found in E. coli isolates. This is the first report of OXA-48-producing Enterobacteriaceae in wild animals from Algeria and Africa.

    The barriers to patients' successful medication intake behavior could be reduced through tailored communication about these barriers. The aim of this study is therefore (1) to develop a new communication typology to address these barriers to successful medication intake behavior, and (2) to examine the relationship between the use of the typology and the reduction of the barriers to successful medication intake behavior. Based on a literature review, the practical and perceptual barriers to successful medication intake behavior typology (PPB-typology) was developed. The PPB-typology addresses four potential types of barriers that can be either practical (memory and daily routine barriers) or perceptual (concern and necessity barriers). The typology describes tailored communication strategies that are organized according to barriers and communication strategies that are organized according to provider and patient roles. Eighty consultations concerning first-time medication use between nurses and inflammatory bowel disease patients were videotaped. The verbal content of the consultations was analyzed using a coding system based on the PPB-typology. The Medication Understanding and Use Self-efficacy Scale and the Beliefs about Medicine Questionnaire Scale were used as indicators of patients' barriers and correlated with PPB-related scores. The results showed that nurses generally did not communicate with patients according to the typology. However, when they did, fewer barriers to successful medication intake behavior were identified. A significant association was found between nurses who encouraged question-asking behavior and memory barriers (r = -0.228, P = 0.042) and between nurses who summarized information (r = -0.254, P = 0.023) or used cartoons or pictures (r = -0.249, P = 0.026) and concern barriers. Moreover, a significant relationship between patients' emotional cues about side effects and perceived concern barriers (r = 0.244, P = 0.029) was found as well

    Trape, Sébastien

    In the rare perennial bodies of water of the Sahara desert, only a few fish species have survived to increasing aridification since the end of the last humid period at the Holocene, approximately 5000 years BP. Here, I report the occurrence of an undescribed haplochomine cichlid fish in Lake Boukou, one of the seven Ounianga Serir lakes (Chad). These lakes are located in one of the most arid areas of the Sahara desert, but they persist by virtue of subsurface inflow of fresh groundwater from a large fossil aquifer. Astatotilapia tchadensis sp. nov. is characterized by a black bar between eye and corner of mouth, rounded orange spots on anal fin, scales ctenoid, lower limb of first gill arch with 7-8 gill rackers, dorsal fin with 13-14 spines and 9-11 soft rays, anal fin with 3 spines and 8-9 soft rays, 29 or 30 lateral line scales, and lower pharyngeal dentition with enlarged molariform teeth. The new species is easily distinguished from A. desfontainii and A. flaviijosephii, the northernmost haplochromine species currently isolated from its other group members, and appears close to an unnamed species of Lake Chad basin. Ounianga Serir lakes and especially Lake Boukou present a remarkable diversity of fish, the highest known in the Sahara desert with a total of at least six fish species belonging to six genera and three families. They also constitute an exceptional natural landscape inscribed on the UNESCO world heritage list in 2012 and a biodiversity hotspot for desert vertebrate species.

    Full Text Available This paper attempts to provide a typology of state-seeking nationalisms of the 21stcentury. We collected data using James Minahan's (2002 Encyclopedia ofStateless Nations and from the major newspaper sources with internationalcoverage using Proquest newspaper database from 2000-2010. Based on thesedata we identified over 300 nations, which demand a state for their own, whichhave a well-defined territory,has a flag of their own and an organization whichdemand independence and/or autonomy. This paper examines 174 of these nationswhich have populations over 1 million. These nations are highly different fromeach other in terms of their level of mobilization level of militancy, organizationalcapacity, demands and grievances. Taking these differences into consideration, weestablished a typology of 21st century state-seeking nationalisms. Our typology,which is inspired by Miroslav Hroch's three phases, is not only descriptive incharacter but also suggests how nationalist movements evolve and transform intime.

    This study investigated whether subgroups of alcohol-dependent patients responded differently to naltrexone versus placebo in the NIAAA COMBINE study. In particular, the A versus B and the Early Onset versus Late Onset typologies were examined. Relative to Type A alcoholics, Type B alcoholics are characterized by greater severity, earlier onset, stronger family history, more childhood risk factors (e.g., conduct disorder), and greater frequency of comorbid psychiatric and substance use disorders. COMBINE study participants were categorized as Type A or Type B using k-means cluster analysis and variables from 5 domains that have been shown to replicate the original Babor typology efficiently. Early Onset was defined as alcohol dependence beginning before age 25. For the planned analyses, the sample was reduced to the 618 participants receiving naltrexone alone or placebo, either with medical management (MM) alone or with MM plus the Combined Behavioral Intervention (CBI). The a priori primary outcome was percent heavy drinking days during treatment in the groups receiving MM without CBI. Among those receiving MM without CBI, Type A alcoholics had better drinking outcomes with naltrexone than placebo, whereas medication condition did not influence outcomes significantly in the Type Bs. Age of onset was not significantly related to outcome. For those receiving CBI, no significant effects were found for either typology. In this sample, the beneficial effects of opioid antagonism were limited to Type A alcoholics receiving treatment in a MM model. Future studies should investigate the relationship between clinically relevant genotypes, phenotypes such as typologies, and treatment response. More work is also needed to develop practical algorithms for phenotypic assignment.

    2013-04-01

    Full Text Available Background: The associations between childhood abuse and subsequent criminality and posttraumatic stress disorder (PTSD are well known. However, a major limitation of research related to childhood abuse and its effects is the focus on one particular type of abuse at the expense of others. Recent work has established that childhood abuse rarely occurs as a unidimensional phenomenon. Therefore, a number of studies have investigated the existence of abuse typologies. Methods: The study is based on a Danish stratified random probability survey including 2980 interviews of 24-year-old people. The sample was constructed to include an oversampling of child protection cases. Building on a previous latent class analysis of four types of childhood maltreatment, three maltreatment typologies were used in the current analyses. A criminality scale was constructed based on seven types of criminal behavior. PTSD symptoms were assessed by the PC-PTSD Screen. Results: Significant differences were found between the two genders with males reporting heightened rates of criminality. Furthermore, all three maltreatment typologies were associated with criminal behavior with odds ratios (ORs from 2.90 to 5.32. Female gender had an OR of 0.53 and possible PTSD an OR of 1.84. Conclusion: The independent association of participants at risk for PTSD and three types of maltreatment with criminality should be studied to determine if it can be replicated, and considered in social policy and prevention and rehabilitation interventions.

    Sex work in exchange for kind and cash has long been practiced in Nepal. The HIV prevention program in Nepal is focused mainly on these two typologies of sex work. There might be more typologies of sex work beyond streets and establishments seeking research and programmatic attention. The objective of the study is to explore the differentiated typologies of sex work. This is a cross-sectional study conducted using a qualitative technique. Researchers carried out eight Focus Group Discussions with female sex workers (FSWs) (n = 50) in different places of Tanahu district. Data were analyzed using a deductive thematic analysis approach. We identified a more differentiated typology of sex work. Private contact-based sex work and the covert sex work on the cruising areas along the major highways were common. Sex work has become easier to operate with the advent of new technologies such as cell phone. With limited role of facilitation by brokers and pimps, now FSWs are better off and have longer duration of relationship with clients. Soft prostitution was common, as FSWs complemented their income through sex work. The conventional mode of peer and outreach educational approach needs to be further strengthened and modified according to the changing typology of sex work. HIV testing sites need to be further expanded to cruising areas along the highways.

    In this work, we have measured the selenium content in wheat produced locally in eight different regions of Algeria from east to west, and we have established the annual consumption of selenium for five socio-professional categories. Instrumental neutron activation analysis is used. The selenium levels in wheat samples varied from 21 (Tiaret) to 153 μg/kg (Khroub), with a mean value about 52 μg/kg. The mean of selenium daily consumption from ingestion of wheat per person in the eight regions varied from 32 to 52 μg/day which is close to the minimal FAO recommendation. - Highlights: ► Cereals and cereal products represent a staple food in Algeria. ► The objective of this study is to determine the Se intake in wheat produced locally. ► The concentration of Se in the wheat reflects the level of the Se in regional soils. ► The mean of Se daily consumption is close to the minimal WHO/FAO recommendation.

    During the 1970's, thanks to oil exploitation income, Algeria, Iraq and Libya seemed to be engaged in an accelerated modernization process. Petroleum was the blessing that would allow these states to catch up on their economic gap. Algeria was introduced as a 'Mediterranean dragon', Libya as an 'emirate' and Iraq as the leading military power of the Arab world. On the political side, the progressive socialism made one think that deep social transformations were in progress. Several decades later, the disappointment is painful. The prosperity feeling has led these countries into political, economic and military impasses with disastrous consequences for their populations. This book analyses the reasons that have led to this political/economical/social situation. The questions are: how can these countries get rid of deep reforms without any risk of social explosion, and how can the European Union export its standards and values and protect its gas imports at the same time?

    The chemical composition, antibacterial and antioxidant activities of the essential oil obtained from Eryngium triquetrum from Algeria were studied. The chemical composition of sample oils from 25 locations was investigated using GC-FID and GC/MS. Twenty-four components representing always more than 87% were identified in essential oils from total aerial parts of plants, stems, flowers and roots. Falcarinol is highly dominant in the essential oil from the roots (95.5%). The relative abundance of falcarinol in the aerial parts correlates with the phenological stages of the plant. Aerial parts of E. triquetrum produce an essential oil dominated by falcarinol during the early flowering stage, and then there is a decrease in falcarinol and rebalancing of octanal during the flowering stage. To our knowledge, the present study is the first report of the chemical composition of E. triquetrum essential oil. Evaluation of the antibacterial activity by means of the paper disc diffusion method and minimum inhibitory concentration assays, showed a moderate efficiency of E. triquetrum essential oil. Using the DPPH method, the interesting antioxidant activity of E. triquetrum essential oil was established. These activities could be attributed to the dominance of falcarinol. The outcome of our literature search on the occurrence of falcarinol in essential oils suggests that E. triquetrum from Algeria could be considered as a possible source of natural falcarinol. © 2018 Wiley-VHCA AG, Zurich, Switzerland.

    Absent for several decades, the chancroid reappeared in Algeria in 1988. In the unique department of Dermatology and Venereology of the University Hospital of the country of Tlemcen (more than 700,000 inhabitants), we wanted to know the state of this STD seven years after the report of the first cases. The file of the consulting patients were examined. We looked for the principal characteristics of this STD: age, sex, incubation period, place infection contact, type of relation, clinical presentation, evolution without and with treatment, other associated STD (syphilis, HIV). From August 1988 (1st case) to December 1995, 144 cases of chancroid were collected = 1988: 6, 1989: 5, 1990: 7, 1991: 18, 1992: 11, 1993: 33, 1994: 48, 1995: 16. The presentation is quite stereotyped; it concerns males only, singles in must cases, having had sexual relations with prostitutes. The incubation period is short (less than 10 days), the characteristic ulceration presents, very often, some adenopathies. The treatment by cotrimoxazole is efficient. They are no concomitant syphilis or HIV infection. The chancroid is the first cause of genital ulceration in the world. Since 1991, it is the principal STD in our department. It spreads within a male population, young singles associated with prostitutes. It is well installed in Algeria, and its role, although minor, in the transmission of the HIV infection, should not be neglected.

    This study aims to develop a typology of generic meeting places based on social contact and mixing of relevance for infectious disease transmission. Data were collected by means of a contact diary survey conducted on a representative sample of the Swedish population. The typology is derived from a cluster analysis accounting for four dimensions associated with transmission risk: visit propensity and its characteristics in terms of duration, number of other persons present and likelihood of physical contact. In the analysis, we also study demographic, socio-economic and geographical differences in the propensity of visiting meeting places. The typology identifies the family venue, the fixed activity site, the family vehicle, the trading plaza and the social network hub as generic meeting places. The meeting place typology represents a spatially explicit account of social contact and mixing relevant to infectious disease modelling, where the social context of the outbreak can be highlighted in light of the actual infectious disease.

  19. Role of Surface Wind and Vegetation Cover in Multi-decadal Variations of Dust Emission in the Sahara and Sahel

    North Africa, the world's largest dust source, is non-uniform, consisting of a permanently arid region (Sahara), a semi-arid region (Sahel), and a relatively moist vegetated region (Savanna), each with very different rainfall patterns and surface conditions. This study aims to better understand the controlling factors that determine the variation of dust emission in North Africa over a 27-year period from 1982 to 2008, using observational data and model simulations. The results show that the model-derived Saharan dust emission is only correlated with the 10-m winds (W10m) obtained from reanalysis data, but the model-derived Sahel dust emission is correlated with both W10m and the Normalized Difference Vegetation Index (NDVI) that is obtained from satellite. While the Saharan dust accounts for 82 of the continental North Africa dust emission (1340-1570 Tg year(exp -1) in the 27-year average, the Sahel accounts for 17 with a larger seasonal and inter-annual variation (230-380 Tg year(exp -1), contributing about a quarter of the transatlantic dust transported to the northern part of South America. The decreasing dust emission trend over the 27-year period is highly correlated with W10m over the Sahara (R equals 0.92). Over the Sahel, the dust emission is correlated with W10m (R 0.69) but is also anti-correlated with the trend of NDVI (R equals 0.65). W10m is decreasing over both the Sahara and the Sahel between 1982 and 2008, and the trends are correlated (R equals 0.53), suggesting that Saharan Sahelian surface winds are a coupled system, driving the inter-annual variation of dust emission.

    2015-03-01

    As human-computer interaction (HCI) is becoming a significant part of all human life, the user's emotional satisfaction is an important factor to consider. These changes have been pointed out by several researchers who claim that a user's personality may become the most important factor in the design. The objective of this study is to examine Sasang typology as a user segmentation method in the area of HCI design. To test HCI usage patterns in terms of the user's personality and temperament, this study focuses on personal computer (PC) or lap-top wallpaper settings. One hundred and four Facebook friends completed a QSCC II survey assessing Sasang typology type and sent a captured image of their personal PC or lap-top wallpaper. To classify the computer usage pattern, folder organization and wallpaper setting were investigated. The research showed that So-Yang type organized folders and icons in an orderly manner, whereas So-Eum type did not organize folders and icons at all. With regard to wallpaper settings, So-Yang type used the default wallpaper provided by the PC but So-Eum type used landscape images. Because So-Yang type was reported to be emotionally stable and extrovert, they tended to be highly concerned with online privacy compared with So-Eum type. So-Eum type use a lot of images of landscapes as the background image, which demonstrates So-Eum's low emotional stability, anxiety, and the desire to obtain analogy throughout the computer screen. Also, So-Yang's wallpapers display family or peripheral figures and this is due to the sociability that extrovert So-Yang types possess. By proposing the Sasang typology as a factor in influencing an HCI usage pattern in this study, it can be used to predict the user's HCI experience, or suggest a native design methodology that can actively cope with the user's psychological environment.

    2013-12-01

    North Africa is the world's largest source of mineral aerosol (dust). The Fennec Project, an international consortium led by the University of Oxford, is the first project to systematically instrument the remote central Sahara Desert. These observations have, among others, provided new insights into the atmospheric mechanisms of dust emission. Bordj Badji Mokhtar, in south-west Algeria, is within kilometres of the centre of the global mean summer dust maximum. The site, operated by Fennec partners ONM Algerie, has been heavily instrumented since summer 2011. During the Intensive Observation Period (IOP) in June 2011, four main emission mechanisms were observed and documented: cold pool outflows, low level jets (LLJs), monsoon surges and dry convective plumes. Establishing the relative importance of dust emission mechanisms has been a long-standing research goal. A detailed partitioning exercise of dust events during the IOP shows that 45% of the dust over BBM was generated by local emission in cold pool outflows, 14% by LLJs and only 2% by dry convective plumes. 27% of the dust was advected to the site rather than locally emitted and 12% of the dust was residual or ';background' dust. The work shows the primacy of cold pool outflows for dust emission in the region and also the important contribution of dust advection. In accordance with long-held ideas, the cube of wind speed is strongly correlated with dust emission. Surprisingly however, particles in long-range advection (>500km) were found to be larger than locally emitted dust. Although a clear LLJ wind structure is evident in the mean diurnal cycle during the IOP (12m/s peak winds at 935hPa between 04-05h), LLJs are only responsible for a relatively small amount of dust emission. There is significant daily variability in LLJ strength; the strongest winds are produced by a relatively small number of events. The position and strength of the Saharan Heat Low is strongly associated with the development (or

    The recent fragile tectonic in the region of Hammam-bouhadjar, Oran, Algeria led to the emergency of a thermomineral sources network. The flows are variable and depend mainly on the degree of the plugging of fissures. The resistivities included between 140 Ohm/cm 2 /cm and 280 Ohm/cm 2 /cm show hypermineralized waters. By and large, the pH is close to 7 for temperatures included between 35 and 70 degrees Celcius (author)

    Two qualitative methodologies were used to develop a life course typology of individuals who had been exposed to sexual violence. Interview narratives of 121 adult women and men who participated in qualitative study of women’s and men’s responses to sexual violence provided the data. The authors combined a narrative approach (holistic-content and holistic-form analysis) to describe the life courses of the participants and a qualitative person-oriented approach (cross-case analysis) to identify meaningful sub-groups within the total sample. The six groups are: (a) life of turmoil, (b) life of struggles, (c) diminished life, (d) taking control of life, (e), finding peace in life, and (f) getting life back to normal. This work exemplifies a promising strategy for identifying sub-groups of violence-exposed individuals within a heterogeneous sample. Such a typology could aid the development of treatment approaches that consider both the substance and the structure of an individual’s life course, rather than target one specific type of violence.

    Full Text Available The analysis of language semantics of the polysemantic verbs kel and kommen of the modern Yakut and German languages brings us to the domain of concepts. Interest in typological studies of languages, in particular, in comparative studies of concept structure of polysemantic verbs has increased thanks to cognitive linguistics which is currently the most intensively developing field of linguistics. The direct nominative meaning of the Yakut verb kel and the German kommen reflects the main components of the concept structure that can be assigned to the concept core: object, operation, result. The purpose of this paper is the typological analysis of lexicographic codification of the phenomenon of polysemy in various languages of the Turkic and German language families. The study is of complex character; to reveal universal and specific ethnic-cultural features of compared Yakut and German linguistic units we used the inductive-deductive method, i.e. theoretical conclusions result from the analysis of practical material. Using the component analysis, lexical units were separated into smallest meaningful parts. Distributive method was used to analyze actualization of meanings of the Yakut and German polysemantic verbs ‘kel’ and ‘kommen’ in context. The typological analysis was invoked to reveal ethnic specifics of compared Yakut and German polysemantic verbs. The polysemantic verbs kel and kommen share the following concepts through subject: ‘man’, ‘animal’, ‘time’, ‘artifact’, ‘emotional-physical state’, and ‘abstract notion’. All concepts given above, 15 lexico-semantic variants, 2 grammatical meanings of the polysemantic word kel and 18 meanings of the verb kommen are represented and codified according to all lexicographic rules and requirements in the Great Academic Dictionary of the Yakut Language and the Great German-Russian Dictionary that are an inexhaustible source for further research into comparative and

    Objectives: This article reports comparisons of the Giessen Test (GT) with the NEO-Five-Factor-Inventory (NEO-FFI) based on a dimensional as well as on a typological approach. Method: Data were collected from 1673 subjects (aged between 18 and 96 years) constituting a representative sample of the German population. Results: The results indicate only moderate agreement (ranging from .25 to .61) between the subscales of the two personality inventories. The correspondence seems to be somewhat higher, when the typological approach was used instead of the dimensional approach. Conclusions: The typological approach is less dependent on the underlying questionnaires and provides a useful extension of the dimensional approach. PMID:19742276

    The air over major cities and rural regions of the Nile Delta is highly polluted during autumn which is the biomass burning season, locally known as black cloud. Previous studies have attributed the increased pollution levels during the black cloud season to the biomass or open burning of agricultural waste, vehicular, industrial emissions, and secondary aerosols. However, new multi-sensor observations (column and vertical profiles) from satellites, dust transport models and associated meteorology present a different picture of the autumn pollution. Here we show, for the first time, the evidence of long range transport of dust at high altitude (2.5-6 km) from Western Sahara and its deposition over the Nile Delta region unlike current Models. The desert dust is found to be a major contributor to the local air quality which was previously considered to be due to pollution from biomass burning enhanced by the dominant northerly winds coming from Europe. - New evidence of desert dust transport from Western Sahara to Nile Delta during black cloud season and its significance for regional aerosols, dust models, and potential impact on the regional climate.

    2012-12-01

    Full Text Available The aim of this project was to obtain a scientists-validated Typology System, which would allow to classify the surface waters bodies in Chile and, therefore, to facilitate the environmental institutional water management in the country. For this, during the years 2009 and 2011, a Typology System for the surface freshwater bodies was developed for Chile based on the methodology described by the Water Framework Directive of the European Union, which was adapted to local features through the knowledge of limnologist experts in the country, as well as policy makers' experience and their management requirements . In a first stage, national ecoregions were developed and abiotic variables were defined to compose the Typology System. The resulted Typology System for lakes and rivers was generated following an a priori and top down approach to difference biocenosis, based on geomorphologic, hydrologic and physic criteria. In a second stage, the proposed Typology System was validated by experts and policy makers, in which process new arrangements were included in the system. The working methodology used for both stages was bibliographic review, interviews to local experts in biocenosis and workshops. It is specially highlighted the participative processes and discussions in which all the agents involved were present, all of which resulted in the creation of a valid system from a scientific point of view and a product that is applicable to the necessities of the environmental institutions of the country. This work represents a successful experience in the improvement of the communication between scientists and politicians in Chile, which is a relevant factor for the elaboration of more efficient and effective environmental policies, integrating not only management and economic issues, but also more technical aspects that can influence in the final success of any long term strategy. For this reason, the replication of this kind of experiences, as well as

    This paper considers the support networks of older people in populations with a preponderance of multigenerational households and examines the most vulnerable network types in terms of loneliness and isolation. Current common typologies of support networks may not be sensitive to differences within and between different cultures. This paper uses cross-sectional data drawn from 590 elders (Gujaratis, Punjabis and Sylhetis) living in the United Kingdom and South Asia. Six variables were used in K-means cluster analysis to establish a new network typology. Two logistic regression models using loneliness and isolation as dependent variables assessed the contribution of the new network type to wellbeing. Four support networks were identified: 'Multigenerational Households: Older Integrated Networks', 'Multigenerational Households: Younger Family Networks', 'Family and Friends Integrated Networks' and 'Non-kin Restricted Networks'. Older South Asians with 'Non-kin Restricted Networks' were more likely to be lonely and isolated compared to others. Using network typologies developed with individualistically oriented cultures, distributions are skewed towards more robust network types and could underestimate the support needs of older people from familistic cultures, who may be isolated and lonely and with limited informal sources of help. The new typology identifies different network types within multigenerational households, identifies a greater proportion of older people with vulnerable networks and could positively contribute to service planning.

    Full Text Available This paper explores video game trailers, their various forms and the roles they play within video game industry and culture. It offers an overview of the current practice of video game trailer differentiation and proposes a new typology of video game trailers based on their relation to ludic and cinematic aspects of a video game, combining the theory of paratexts, video game performance framework, the interface effect concept, as well as the concept of transmedia storytelling. This typology reflects the historical evolution of a video game trailer and also takes into account current trends in the audiovisual paratexts of video games.

  12. The uncertain future of hydrocarbons in Algeria

    Auge, Benjamin

    2013-01-01

    As it has been historically the first oil and gas producer in Africa with Gabon and Nigeria (it is now the third oil producer after Nigeria and Angola, and still the first gas producer), Algeria has faced a strong decrease of investments in this sector for the past ten years, for legal, security and political reasons. This resulted in a decrease of production whereas local consumption has been strongly increasing. The author examines whether measures voted in 2012 will be able to bring back the confidence of foreign investors which is needed to develop the huge oil, gas and shale gas potentials of this country. The author recalls this high resource level, and comments the role and behaviour of Sonatrach, the national company, and the consequences of the oil and gas revenues decrease. He outlines the importance of the issue of security (notably terrorism by AQMI), and comments expectations associated with the new law on hydrocarbons

    Social environmental assessments can play a critical role in prevention planning in schools. The purpose of this study was to describe the importance of conducting social environmental assessments, demonstrate that complex social environmental data can be simplified into a useful and valid typology, and illustrate how the typology can guide prevention planning in schools. Data collected from 532 3(rd) through 5(th) graders using the Elementary School Success Profile were analyzed in the study. A latent profile analysis based on eight child-report social environmental dimensions identified five patterns of social environmental risk and protection. The classes were labeled High Protection, Moderate Protection, Moderate Protection/Peer Risk, Little Protection/Family Risk, and No Protection//School Risk. Class membership was significantly associated with measures of well-being, social behavior and academic performance. The article illustrates how the typology can be used to guide decisions about who to target in school-based preventions, which features of the social environment to target, and how much change to seek. Information is provided about online resources for selecting prevention strategies once these decisions are made.

  14. Total reduplication in Japanese ideophones: An exercise in Localized Canonical Typology

    Full Text Available Cross-linguistically, reduplication associated with iconic readings, such as plurality, iteration, and continuation, is prevalent in ideophones. However, not all reduplicative processes in ideophones are clearly iconic. Notably, both less and more iconic uses of reduplication are encountered in ordinary vocabulary resulting in the overlapping semantic functions of reduplication between ideophonic and non-ideophonic (i.e., prosaic lexical categories. Given this, the aim of this paper is not to establish one clear-cut point to distinguish ideophonic reduplication from prosaic reduplication that may be impossible, but to specify dimensions of possibilities along which several instances of ideophonic and prosaic reduplication can be calibrated, using Canonical Typology (Corbett 2003; 2005; 2006; 2007; 2012; 2015. The current paper adopts the canonical approach of typology in an innovative way – not to compare a reduplicative phenomenon across languages (classic “typology”, but within a language by drawing ideophonic and prosaic data from Japanese, which is rich in reduplication and ideophones. Measuring the canonicity values of the various occurring types of ideophonic and prosaic reduplication against six criteria for canonical ideophonic reduplication, this paper shows how many and what criteria can differentiate the two sets of phenomena. Consequently, it reveals how ideophonic and prosaic reduplication are alike or different from each other. It also demonstrates the utility of Localized Canonical Typology, for the precise description and analysis of complex categories in a single language.

    Full Text Available Sahara dust storms during March 2004 have attracted much attention from the dust-research community due to their intensity, wide coverage, and endurance. In the present work, the dry deposition mechanisms of mineral dust are analysed during an event on the 3 March 2004 over the Northwest African coast. This particular case was chosen based on the strong dry removal that occurred, rendering it ideal for examining the deposition processes. The simulation of synoptic conditions and dry deposition of four dust particles including clay, small silt, large silt, and sand was performed with Eta model, coupled with a desert dust cycle module. The results have been compared with surface data from weather stations in North Africa, data of dry metals from stations located in Gran Canaria, and various satellite images such as European Organization for the Exploitation of Meteorological Satellites and Moderate Resolution Imaging Spectroradiometer for the period in question.

    Full Text Available Background: Neural tube defects (NTDs are severe birth defects, with genetic and/or environmental risk factors. Aim: The objective of this study was to analyze data on NTDs cases at the Batna Maternity Hospital and to investigate some environmental and two genetic risk factors suspected in the etiology of NTDs. Subjects and methods: This study was conducted on 82 healthy participants and 48 mothers with an NTD child. Peripheral blood samples were collected, in EDTA tubes and frozen at −20 °C until DNA extraction by conventional method. Genetic analysis of methylene tetrahydrofolate reductase C677T polymorphism was determined by real time PCR, while cystathionine-beta-synthase 844 insertion was investigated by traditional PCR. Chi-square analyses were used to evaluate differences in the distribution of data. The odds-ratio was also calculated. A P-value less than 0.05 were significant. Results: The incidence of NTD in Batna region was 1.58 per 1000 births. The rate of NTD was significantly higher in females than males, highest affected NTD newborn’s was observed in mothers aged between 25 and 29 years and the consanguinity among all NTD cases was 30%. Data showed no significant association of NTDs with personal education, obesity, diabetes, but regarding folic acid consumption, about 86% of NTD’s mothers in our region didn’t take pre-conceptional supplementation with this vitamin .Genetic factors results didn't show a significant association of NTDs with specific mutations of the variant C677T MTHFR, and no gene-gene interaction of CBS insertion and C677T polymorphism was found, despite a significant difference in heterozygote frequency of CBS 844ins68 genotype between NTD’s mothers and controls, OR: 2.85(1.18–6.88. Conclusion: NTD represents a real public health problem in Batna, Algeria. Various genetic and/or nutritional factors are implicated, although the mechanism is not clear. We suggest that further research should continue

    The renewable energy projects are tools for the management of reserves and sustainable development of desert communities. These are generally areas wher a diesel or gas-powered generator present a problem of fuel transportation and may potentially harm the environment. Tremendous opportunities exist in Algeria for growth in the use of renewable energy technologies in particular photovoltaic solar power. According to some estimates, more than five million Algerians do not have access to grid electricity, while many rural communities are in need of drinking water and water for livestock or irrigation. Given Algerian's abundant solar resource, these rural needs represent a potential market for renewable energy technologies. Nowadays a growing number of people in the south of Algeria are using renewable energy to irrigate their land, light their houses, pump well water and then improve their lives, thanks to the 'Ministere de l'Energie et des Mines' and the Sonelgaz (Societe Nationale de l'Electricite et du Gaz) R and D office. From 1999 up 2002. Sonelgaz Renewable Energy Program, and the above mentioned ministry have collaborated and sponsored several photovoltaic projects in 20 villages of the desert of Algeria concerning this renewable energy program aiming at increasing the use of renewable energy technologies, thus providing green power to isolated villages. Sonelgaz's role in the project is to initiate renewable energy pilot projects that could be easily replicated by area residents and provide training with technical assistance. Based on its feasibility, potential projecs are initially identified and selected by the Sonelgaz R and D office which develops system requirements, provides technical review, evaluates and monitors the projects following their installation. Since 1999, Sonelgaz has received 988 millions of DA (Algerian Dinars) to operate the program. Most activities focus on house lighting and implementing water pumping systems. For most of these

    Social space is various forms of spaces used by community in conducting social interaction. These kinds of spaces should be given more attention since they serve as catalyst in the implementation of good social cohesion in community. The effort includes giving concern toward their various implemented form. This concern will give benefits in the creation of resilient built environment. Kauman Kampong in Semarang, is an old urban kampong and still exist up until now. During its development, the inhabitant live and conduct their activities in good shape. Therefore this kampong is an appropriate place to learn and explore social spaces which is formed and utilized by the community who conduct their activities in this kampong. The aim of this research is to find out forms and typology of social space in Kauman Kampong in Semarang. Qualitative method is used in this research since the nature of this research is explorative. There are various social activities in Kauman Kampong in Semarang, such as religious, trading, and other social interaction, which have formed various social spaces. These social spaces have their own physical characteristics and with various intensity of activities. Based on collected data in field survey, the typology of social spaces that could be inferred are: permanent, temporary, and dynamic social space.

    To evaluate the antifungal activity of four honeys of different types from Algeria against pathogenic yeast i.e. Candida albicans (C. albicans) and Rhodotorula sp. Four Algeria honeys of different botanical origin were analyzed to test antifungal effect against C. albicans, and Rhodotorula sp. Different concentrations (undiluted, 10%, 30%, 50% and 70% w/v) of honey were studied in vitro for their antifugal activity using C. albicans and Rhodotorula sp. as fungal strains. The range of the diameter of zone of inhibition of various concentrations of tested honeys was (7-23 mm) for Rhodotorula sp., while C. albicans showed clearly resistance towards all concentrations used. The MICs of tested honey concentrations against C. albicans and Rhodotorula sp. were (70.09-93.48)% and (4.90-99.70)% v/v, respectively. This study demonstrates that, in vitro, these natural products have clearly an antifungal activity against Rhodotorula sp. and C. albicans.

    A sample of eight private gasoline and diesel conventional light-duty vehicles (LDVs) in use with various ages, carrying a load of 460 kg, were tested on a representative trip in the traffic flow of the city of Blida to obtain emission factors representing the actual use conditions of Algerian LDVs. The gas sampling system (mini-constant volume sampling) as well as the analyzers are carried on-board the vehicle. Around 55 tests were conducted during 3 months covering more than 480 km under various real driving conditions. The mean speed downtown is about 16.1 km/hr with a rather low acceleration, an average of 0.60 m/sec2. For each test, kinematics are recorded as well as the analysis of the four emitted pollutants carbon dioxide, carbon monoxide, oxides of nitrogen, and total hydrocarbons. Emission factors were evaluated according to speed for each category of gasoline and diesel engines. The influence of some parameters such as cold/hot start, age of vehicle and its state of maintenance are discussed. Results are compared with the European database ARTEMIS for comparable vehicles. These measurements contribute to the development of unit emission of the vehicles used in Algeria, which are necessary for the calculation of emission inventory of pollutants and greenhouse gases from the road transportation sector. The unit emissions constitute a tool of decisionmaking aid regarding the conception of new regulations of vehicle control and inspection in Algeria and even in similar developing countries.

    The Afro-Arabian Paleogene fossil record of Chiroptera is very poor. In North Africa and Arabia, this record is limited, thus far, to a few localities mainly in Tunisia (Chambi, late early Eocene), Egypt (Fayum, late Eocene to early Oligocene), and Sultanate of Oman (Taqah, early Oligocene). It consists primarily of isolated teeth or mandible fragments. Interestingly, these African fossil bats document two modern groups (Vespertilionoidea and Rhinolophoidea) from the early Eocene, while the bat fossil record of the same epoch of North America, Eurasia, and Australia principally includes members of the "Eochiroptera." This paraphyletic group contains all primitive microbats excluding modern families. In Algeria, the region of Brezina, southeast of the Atlas Mountains, is famous for the early Eocene El Kohol Formation, which has yielded one of the earliest mammalian faunas of the African landmass. Recent fieldwork in the same area has led to the discovery of a new vertebrate locality, including isolated teeth of Chiroptera. These fossils represent the oldest occurrence of Chiroptera in Africa, thus extending back the record of the group to the middle early Eocene (Ypresian) on that continent. The material consists of an upper molar and two fragments of lower molars. The dental character association matches that of "Eochiroptera." As such, although very fragmentary, the material testifies to the first occurrence of "Eochiroptera" in Algeria, and by extension in Africa.

    Full Text Available Analyzed anthropo-saving and environmental-depth approaches to understanding the essence environmentalism. The definition of environmentalism as global environmental trends that recognizes the intrinsic value of the natural world, all its elements and aims to rescue mankind from global environmental threats by achieving a sustainable balance of planetary ecosystems, the proper state of the environment and harmonious development of man and nature. Developed the typology of globalization consciousness attitude to solving global problems in the relationship between man and nature. The main types globalistion consciousness, as the growth of thrift in relation to nature, located in the following sequence: ecodestructive, anthropocentric, ecoconsumerist, ecotraditional, environmental, sacred-ethical, naturecentric and antropofobiastic. Developing a typology of globalistion consciousness above criteria also highlighted its neutral type. Proved that environmental globalistion consciousness is environmentally oriented system of ideas that reflect solutions to global environmental problems in accordance with the principles environmentalism. This type of consciousness globalistion a high degree of awareness of global environmental problems, persistent desire to implement effective methods of humane solution, the optimal it is due, the need to maximize the spread of population. It is concluded that the formation environmental globalistion consciousness as a prerequisite for saving humanity from self created global environmental threats can be greatly accelerated by the terms of the assistance of governments, the media, educational institutions, political parties, public organizations and other institutions of political socialization.

    Highlights: • Wind resource assessment in the northwestern part of Algeria using WAsP Software. • Comparison between the performances of 6 WECs at 3 sites with great potential. • Assessment of the wind power cost per kW h of electricity produced. • Stall-regulated wind turbines are more appropriated for Site 1. • Pitch-regulated wind turbines are suggested for the windiest Site. - Abstract: In this work, ten years of wind data from Oran meteorological station have been used to evaluate the potential of wind power on the Oranie region, in the North-western part of Algeria, open on the Mediterranean Sea. The WAsP program was used to analyze the wind Atlas of the region to find the windiest areas. Three regions were chosen for their great wind potential. The study proposes to assess wind power cost per kW h of electricity produced using six types of WECs. The investigation at 10 m above ground at the location of the meteorological station shows that Oran has an average wind potential, with an annual mean wind speed equal to 4.2 m/s and an annual mean power density of 129 W/m 2 . The temporal study shows that spring period is the windiest with 4.9 m/s. In terms of energy production, the results show that the second site is the best location for harnessing the wind power to generate electricity. The minimum cost per kW h of electricity generated in that location is about 0.0181$/kW h with a capacity factor equal to 51.36% for an annual energy production equal to 11.14 GW h, given by the Power Wind 90 wind turbine of 2.5 MW power rated capacity.

  14. A Typology of Benefit Sharing Arrangements for the Governance of Social-Ecological Systems in Developing Countries

    2012-03-01

    Full Text Available This study explores and interprets relevant literature to construct a typology of benefit sharing arrangements for the governance of social-ecological systems in developing countries. The typology comprises three generic categories of benefit sharing arrangements: collaborative, market-oriented, and egalitarian. We contend that the three categories provide a useful basis for exploring and classifying the different societal arrangements required for governance of social-ecological systems. The typology we present is founded on a related set of explicit assumptions that can be used to explore and better understand the linkages among ecosystem services, benefit sharing, and governance. Issues that are strongly related to sustainability in developing countries form the core basis of our assumptions. Our aim is not to write a definitive exposition, but to spark debate and engage ongoing dialogue on governance and benefit sharing in the field of social-ecological systems.

    2014-08-01

    The human need for love, friendship, and physical contact, and the fear of loneliness do not diminish with age. Widowhood and late-life divorce and increased life expectancy are likely to lead to alternative relationships, such as re-partnering. The purpose of this paper is to explore interplays between emotional and physical components of re-partnering in old age. Theoretical sampling of 20 couples included men who re-partnered at the age of 65+ years and women at the age of 60+ years, following termination of lifelong marriages due to death or divorce. Living arrangements included married or unmarried cohabitation under the same roof or in separate homes. Forty semi-structured interviews were tape-recorded and transcribed verbatim. The couple was the unit of analysis. Interplays between physical and emotional dimensions were examined using five abductive parameters derived from data analysis resulting in a fourfold typology of emotional and physical closeness/distance in re-partnering in old age: (1) living together (physically and emotionally); (2) living apart (physically) together (emotionally); (3) living together (physically) apart (emotionally); and (4) living apart (physically and emotionally). Findings revealed types of partner relationships that are different from lifelong marriages. The typology could help professionals working with older persons regarding what to expect in re-partnering in old age and be included in developmental theories as an option in old age. A quantitative tool for research and therapy purposes, entitled The Re-partnering in Old Age Typology Scale (RPOAT Scale), based on abductive parameters, could be established for measuring re-partnering relationship quality and classifying re-partnering couples.

    This study aimed to elucidate the understandings and beliefs about quality held by family members of residents of Norwegian nursing homes. The objective reported in the study considers how family member judge factors that enhance or hamper high care quality. The percentage of those who will require care in a nursing home some time before the end of their lives will increase dramatically in the next 20 years. Therefore, anticipating this pressure to expand nursing home availability, it is urgent that these services are developed from a keen understanding of what creates the best value. Care quality from the family's perspective is just one piece of the nursing home experience that must be understood for optimal value in care to be realised. Qualitative methodology. Three focus group interviews; purposive sampling was used to recruit the 16 family members of residents in nursing homes. Three domains emerged that served as anchors for a typology of family perceptions of the quality care continuum: resident contentment, suitability of staff and environmental context. Each domain was developed with categories describing high- to low-quality markers, which were then clarified by enhancing and hindering factors. This typology provides a family perspective framework that may be useful to nursing leadership at all levels of the nursing home organisation to identify important quality of care strengths as well as markers of poor care. Overall, the typology is offered to expand nurses' understanding of quality, both practically and conceptually, to provide the best value in nursing care. © 2011 Blackwell Publishing Ltd.

The aim of this study is therefore (1 to develop a new communication typology to address these barriers to successful medication intake behavior, and (2 to examine the relationship between the use of the typology and the reduction of the barriers to successful medication intake behavior.Patients and methods: Based on a literature review, the practical and perceptual barriers to successful medication intake behavior typology (PPB-typology was developed. The PPB-typology addresses four potential types of barriers that can be either practical (memory and daily routine barriers or perceptual (concern and necessity barriers. The typology describes tailored communication strategies that are organized according to barriers and communication strategies that are organized according to provider and patient roles. Eighty consultations concerning first-time medication use between nurses and inflammatory bowel disease patients were videotaped. The verbal content of the consultations was analyzed using a coding system based on the PPB-typology. The Medication Understanding and Use Self-efficacy Scale and the Beliefs about Medicine Questionnaire Scale were used as indicators of patients’ barriers and correlated with PPB-related scores.Results: The results showed that nurses generally did not communicate with patients according to the typology. However, when they did, fewer barriers to successful medication intake behavior were identified. A significant association was

    This publication proposes a rather detailed and discussed overview of the movement of mobilisation of Algerian people (notably those living in the Sahara) against projects of exploration and exploitation of shale gases in Algeria by the Total group. The authors also recall and comment the long and heavy history of hydrocarbon management in Algeria, the role of international firms and of western interests (notably French interests) in this country, and the position of Total regarding the stake related to shale gases. The authors outline problems created by shale gas exploitation regarding water consumption and waste waters. They also notice that the safety of wells is at the centre of the protest. Problems raised by hydraulic fracturing are reviewed: seismic activity, chemical pollution, air pollution and greenhouse gases, landscape destruction. The attitude of the Algerian government is commented. Then, the authors try to identify and describe the action of Total in the Algerian shale gas sector, discuss the possible French influence, and outline the presence of Total all over the world in this sector

    Full Text Available Objective: To evaluate the antibacterial effect of Sahara honeys (SHs against bacterial biofilms formed on urinary catheters in combination with propolis-Sahara honeys (P-SHs. Methods: Three clinical isolates were subjected to biofilm detection methods. The antibacterial and anti-biofilm activity for SHs and P-SHs were determined using agar well diffusion and the percentage of biofilm inhibition (PBI methods. Results: The PBI for Gram-positive bacteria [Staphylococcus aureus (S. aureus] was in the range of 0%–20%, while PBI for Gram-negative bacteria [Pseudomonas aeruginosa and Escherichia coli (E. coli] were in range of 17%–57% and 16%–65%, respectively. The highest PBI (65% was produced by SH2 only on E. coli. In agar well diffusion assay, zones of inhibition ranged from 11–20 mm (S. aureus, 9–19 mm (Pseudomonas aeruginosa and 11–19 mm (E. coli. The highest inhibition (20 mm was produced by SH1 only on S. aureus. In addition, the treatment of SHs and P-SHs catheters with a polymicrobial biofilms reduced biofilm formation after 48 h exposure period. Conclussions: SHs and P-SHs applied as a natural agent can be used as a prophylactic agent to prevent the formation of in vitro biofilm.

    Rational: Marketers have ever been concerned with the behaviour of consumers. Generation Y consumers have emerged as an important marketing segment. Consequently, a need exists to investigate behavioural issues pertaining to this age cohort on a continuous basis. Methodology: A survey questionnaire was administered to a convenient sample of 230 Generation Y consumers of fashion apparel. Exploratory factor analysis was used to identify shopper typologies. The Kruskal-Wallis test was used to examine the influence of age on the identified shopper typologies. Findings: The study identified seven shopper typologies that are applicable to the Generation Y cohort. These are quality conscious, brand conscious, novelty seeking, hedonistic, confused by over-choice, habitual, brand loyal and fashion conscious shopper typologies. The study also revealed that younger consumers were found to be more confused by over-choice than their older counterparts. Value of research: These findings may enable marketers to understand and predict the purchase behaviour of Generation Y consumers, thereby facilitating the development and implementation of more effective marketing strategies.

    Recognizing cultural diversity among local breed farmers is crucial for the successful development and implementation of farm animal genetic resources FAnGr conservation policies and programmes. In this study based on survey data collected in the EUropean REgional CAttle breeds project from six European countries, a typology of local breed farmers was designed and profiles for each of the farmer types were developed to assist these policy needs. Three main farmer types were constructed: production-oriented, product and service-oriented and hobby-oriented farmers. In addition, seven subtypes were characterized under the main types: sustainable producers, opportunists, multi-users, brand makers, traditionalists, pragmatists and newcomers. These types have many similarities to the 'productivist', 'multifunctional' and 'post-productivist' farmer types. The typology not only reveals the high level of diversity among local cattle breed farmers in Europe, which presents an opportunity for the in situ conservation of animal genetic resources, but also a challenge for policy to meet the differing requirements of the farmer types. © 2012 Blackwell Verlag GmbH.

    Differences in how services are organized and delivered can contribute significantly to variation in outcomes experienced by children and families. However, few comparative studies identify the strengths and limitations of alternative delivery system configurations. The current study provides the first empirical typology of private agencies involved with the formal child welfare system. Data collected in 2011 from a national sample of private agencies were used to classify agencies into five distinct groups based on internal management capacity, service diversification, integration, and policy advocacy. Findings reveal considerable heterogeneity in the population of private child and family serving agencies. Cross-group comparisons suggest that differences in agencies' strategic and structural characteristics correlated with agency directors' perceptions of different pressures in their external environment. Future research can use this typology to better understand local service systems and the extent to which different agency strategies affect performance and other outcomes. Such information has implications for public agency contracting decisions and could inform system-level assessment and planning of services for children and families.

    Joseph Sweetman

    2013-12-01

    Full Text Available To date, there is little in the way of theorizing or empirical work on the imagined endpoint of political action aimed at social change – the type of “dream” those engaged in action are attempting to bring into fruition. We suggest that previous approaches have focused narrowly on one type of social change – amelioration of collective grievances. In contrast, we argue that social change is much richer and imaginative than this narrow focus suggests. In the present article we draw on key constructs in social psychology (e.g., goals, efficacy, legitimacy, identity, social system, and social value in order to develop a typology of social change goals. In doing so, we explain why people might support one type of social change (e.g., revolution versus others (e.g., separatism or amelioration. The typology is used to discuss future directions for research and to highlight the implications for psychological (and broader approaches to social change.

    Full Text Available The aim of this study was to investigate the effects of open and closed sport participation on visuo-spatial attention and memory performance among young adults. Forty-eight young adults—16 open-skill athletes, 16 closed-skill athletes, and 16 non-athletes controls—were recruited for the study. Both behavioral performance and event-related potential (ERP measurement were assessed when participants performed non-delayed and delayed match-to-sample task that tested visuo-spatial attention and memory processing. Results demonstrated that regardless of training typology, the athlete groups exhibited shorter reaction times in both the visuo-spatial attention and memory conditions than the control group with no existence of speed-accuracy trade-off. Similarly, a larger P3 amplitudes were observed in both athlete groups than in the control group for the visuo-spatial memory condition. These findings suggest that sports training, regardless of typology, are associated with superior visuo-spatial attention and memory performance, and more efficient neural resource allocation in memory processing.

    2018-02-01

    In Algeria, the epidemiology of cattle abortions is not well understood. Therefore, the present study aims to estimate the prevalence of abortion in 75 Algerian cattle herds and correlate its possible association with brucellosis positivity and some managerial risk factors. The cattle abortion herd prevalence was 41.33% [95% CI 30.16-52.5%]. As for brucellosis, the serological evidence of brucellosis exposure was observed in 9 out of 75 herds accounting for 12% [95% CI 4.65-19.35] herd seroprevalence. The risk factor analysis using the univariable analysis followed by multivariable logistic regression did confirm that brucellosis positivity (OR = 5.19), mixed herd (OR = 2.5), contact with other herd (OR = 2.91), presence of dog in the herd (OR = 2.89), imported cattle (OR = 1.91), and farmers with less than 2 years' experience (OR = 2.69) as risk factors for abortion in Algerian cattle herds. Targeting these factors using a comprehensive control measure is needed to improve animal welfare and reduce economic losses associated with abortion in dairy cattle.

  16. The image of the family among the victims of rape in Algeria

    2018-04-01

    Full Text Available Post-traumatic clinic research showed that a highly traumatic event, such as rape, is able to upset the balance of the victim and her family. Indeed, as a result of rape, feeling like the shame, the guilt and the inability to cope with the each other’s gaze arise among families of the victims, particularly in some cultural contexts as is the case in Algeria. We recorded attitudes as the refusal and family abandonment among families of the victims, which made them more vulnerable and urged them to develop a chronic PTSD. It seems, in fact, that the negative attitudes of families are the cause of great suffering for the victims.  This is the finding that we made during our clinical work with a dozen victims of rape in Algeria. In this article, I try to identify and analyze, through the dreamlike stories provided by only three of these victims, in our clinical meetings, the multi-faceted or even images related to the representation of the family circle in the context of trauma.                                                                              Keywords: Rape, Victim, Family, Algerian Girl, Dream, Speech, Clinical Interview.

    The main objective of the paper is to do a critic study of the use of typology methodologies within pasture-based farming systems (PBFS), especially those situated in less favoured areas, showing in each case the more relevant variables or indicators determining the farming system classification. Another objective is to do an overview of the most used farming system typology methodologies in general. First some considerations about the concept of farming system and approaches to its study have been done. Next, the farming system typology methodologies have been showed in general to different farming systems, but addressed preferably to PBFS. The different tools integrated in these methodologies have been considered: sampling methods, sources of data, variables or indicators obtained from available data and techniques of analysis (statistical or not). Methods for farming system classification have been presented (expert methods, analytical methods or a combination of both types). Among the statistical methods, the multivariate analysis has been overall treated, including the principal component analysis and the cluster analysis. Finally, the use of farming system typology methodologies on different pasture-based farming systems has been presented. The most important aspects considered are following: the main objective of the typology, the main animal species, the employed methods of classification and the main variables involved in this classification.

    Research on health worker migration in the Irish context has categorized migrant health workers by country or region of training (for example, non-EU nurses or doctors) or recruitment mechanism (for example, actively recruited nurses). This paper applies a new typology of health worker migrants - livelihood, career-oriented, backpacker, commuter, undocumented and returner migrants (European Observatory on Health Systems and Policies and WHO, vol. 2:129-152, 2014) - to the experiences of non-EU migrant doctors in Ireland and tests its utility for understanding health worker migration internationally. The paper draws on quantitative survey (N = 366) and qualitative interview (N = 37) data collected from non-EU migrant doctors in Ireland between 2011 and 2013. Categorizing non-EU migrant doctors in Ireland according to the typology (European Observatory on Health Systems and Policies and WHO, vol. 2:129-152, 2014) offers insight into their differing motivations, particularly on arrival. Findings suggest that the career-oriented migrant is the most common type of doctor among non-EU migrant doctor respondents, accounting for 60 % (N = 220) of quantitative and 54 % (N = 20) of qualitative respondents. The authors propose a modification to the typology via the addition of two additional categories - the family migrant and the safety and security migrant. Employing a typology of health worker migration can facilitate a more comprehensive understanding of the migrant medical workforce, a necessary prerequisite for the development of useful policy tools (European Observatory on Health Systems and Policies and WHO, vol. 2:129-152, 2014). The findings indicate that there is some fluidity between categories, as health worker motivations change over time. This indicates the potential for policy levers to influence migrant health worker decision-making, if they are sufficiently "tuned in" to migrant health worker motivation.

  20. DRINKING WATER CONSUMPTION AND LOSS IN ALGERIA THE CASE OF NETWORKS WITH LOW LEVEL COUNTING

    Full Text Available Demand for drinking domestic water is continuously increasing specially in urban centres which experience high demographic expansion. The decrease of water losses in water supply networks can help preserve such a rare resource. Low number of water meters and intermittent supply make it difficult to quantify the leaking volumes of water. This article presents an analysis of the consumption for drinking water based on an extrapolation from a sample of consumers on whom data are available. Comparison of the volumes of water produced allows a determination of the losses in the water supply system. This analysis is completed by measurements of night flows. The results obtained may be relied on for an evaluation of the needs for drinking water in the South of Algeria, and for future regional development. The study indicates a high rate of water losses in the distribution network, reaching about 40%, and over-consumption due to an insufficient number of water meters and discontinuous supply. It is recommended that water meters come into general use and defective parts of the network are rehabilitated. We will try then to make the necessary recommendations in order to better functioning of the water supply systems in Algeria.

    The prevalence of epilepsy in Algeria is unknown. The aims of this multicenter transversal study were to determine the national prevalence and clinical characteristics of epilepsy in the Algerian population. This two-phase study was conducted in 5 circumscriptions and included 8,046 subjects aged over 2 months who attended the randomly selected public and private primary care clinics. In the phase 1 study, a questionnaire was submitted to the sample of patients. In the phase 2 study, all potentially epileptic people were examined by neurologists and a second questionnaire was submitted, eventually assessed by appropriate investigations. Sixty-seven patients were identified as having active epilepsy, giving a crude prevalence ratio of 8.32 per 1,000 (95% CI, 6.34-10.3) and an age-adjusted prevalence ratio of 8.9 per 1,000. The highest age-specific ratio was found in patients aged 10-19 years (16.92 per 1,000). Generalized seizures (68.7%) were more common than partial seizures (29.8%). Perinatal injuries were the major leading putative causes (11.9%). The prevalence of epilepsy of 8.32 determined in this study is relatively high. These results provide new epidemiological data and suggest that epilepsy remains an important public health issue to consider in Algeria. Copyright © 2012 S. Karger AG, Basel.

    Pesticides generate transformation products (TPs) when they are released into the environment. These TPs may be of ecotoxicological importance. Past studies have demonstrated how difficult it is to predict the occurrence of pesticide TPs and their environmental risk. The monitoring approaches mostly used in current regulatory frameworks target only known ecotoxicologically relevant TPs. Here, we present a novel combined approach which identifies and categorizes known and unknown pesticide TPs in soil by combining suspect screening time-of-flight mass spectrometry with in silico molecular typology. We used an empirical and theoretical pesticide TP library for compound identification by both non-target and target time-of-flight (tandem) mass spectrometry, followed by structural proposition through a molecular structure correlation program. In silico molecular typology was then used to group TPs according to common molecular descriptors and to indirectly elucidate their environmental parameters by analogy to known pesticide compounds with similar molecular descriptors. This approach was evaluated via the identification of TPs of the triazole fungicide tebuconazole occurring in soil during a field dissipation study. Overall, 22 empirical and 12 yet unknown TPs were detected, and categorized into three groups with defined environmental properties. This approach combining suspect screening time-of-flight mass spectrometry with molecular typology could be extended to other organic pollutants and used to rationalize the choice of TPs to be investigated towards a more comprehensive environmental risk assessment scheme. - Highlights: • Combined method to detect and categorize pesticide transformation products in soil. • Detection by QTOF-MS of new tebuconazole transformation products without standards. • Estimation by in silico molecular typology of their environmental parameters. • Method to rationally choose relevant transformation products to be studied. • The

    Wind erosion is one of the most serious environmental problems in Algeria that threatens human activities and socio-economic development. The main goal of this study is to apply a fuzzy logic approach to wind erosion sensitivity mapping in the Laghouat region, Algeria. Six causative factors, obtained by applying fuzzy membership functions to each used parameter, are considered: soil, vegetation cover, wind factor, soil dryness, land topography and land cover sensitivity. Different fuzzy operators (AND, OR, SUM, PRODUCT, and GAMMA) are applied to generate wind-erosion hazard map. Success rate curves reveal that the fuzzy gamma (γ) operator, with γ equal to 0.9, gives the best prediction accuracy with an area under curve of 85.2%. The resulting wind-erosion sensitivity map delineates the area into different zones of five relative sensitivity classes: very high, high, moderate, low and very low. The estimated result was verified by field measurements and the high statistically significant value of a chi-square test.

    Since decolonization till todays "New Odyssey" - the current European refugee crisis—(Kingsley 2016) we witnessed an unhindered and unrestricted migration to Europe from Africa south of the Sahara. Regulated migration was even promoted for medical staff, soldiers and seamen. This was induced by a shortage of qualified staff in receiving ex-colonial powers and the need maintaining mercenary armies for todays international conflicts. Political refugees were often hoped to form new western-friendly governments in cases of socialist Ethiopia and dictatorial regimes in esp. ex-Zaire, Togo, Guinea-Conakry, Uganda, Ghana and Zimbabwe. Todays migration out of Africa south of the Sahara is often caused by political and humanitarian crises, but specifically accelerated by the long-lasting negligence of donors for small-scale agricultural development. Land grabbing and the challenge to bring millions of youth with formal training into a meaningful occupation are seen as further important causes of rural outmigration. A "mismatch" between training programs offered especially by international development agencies and training needs for employability is also causing mass-unemployment of youth. An alignment of future development programming with the needs of the poor to assure a "right to stay" should be addressed by international policy makers with highest priority.

    Full Text Available Query (Q fever is a globally distributed zoonotic disease caused by Coxiella burnetii, a bacterial agent for which ruminants are the most prevalent natural reservoir. Data regarding Q fever infection in camels in Algeria are limited. Therefore, a survey to detect seroprevalence of C. burnetii antibodies was conducted among healthy camel populations in a vast area in southeastern Algeria to determine distribution of the Q fever causative organism and to identify risk factors associated with infection. Between January and March 2016, blood samples were collected from 184 camels and serum samples were subsequently analysed using a commercial Enzyme-Linked Immunosorbent Assay (ELISA kit. At the time of blood collection, a questionnaire investigating 13 potential predisposing factors associated with C. burnetii seropositivity was completed for every dromedary camel and herd. Results were analysed by a chi-square (χ2 test and multivariate logistic regression. The seroprevalence of C. burnetii at the animal level was 71.2% (95% CI: 65.2–78.3 and 85.3% (95% CI: 72.8–97.8 at the herd level. At the animal level, differences in seroprevalence were observed because of herd size, animal age, animal sex, presence of ticks and contact with other herds. A multivariable logistic regression model identified three main risk factors associated with individual seropositivity: (1 age class > 11 years (OR = 8.81, 95% CI: 2.55–30.41, (2 herd size > 50 head (OR = 4.46, 95% CI: 1.01–19.59 and (3 infestation with ticks (OR 2.2; 95% CI: 1.1–4.5. This study of seroprevalence of C. burnetii infection in camels in Algeria revealed a high seroprevalence of Q fever in camel populations in southeastern Algeria and provided strong evidence that Q fever represents an economic, public health and veterinary concern. Appropriate measures should be taken to prevent the spread of C. burnetii and to reduce the risk of Q fever in farm animals and humans in this agro

  12. A typology for campus-based alcohol prevention: moving toward environmental management strategies.

    This article outlines a typology of programs and policies for preventing and treating campus-based alcohol-related problems, reviews recent case studies showing the promise of campus-based environmental management strategies and reports findings from a national survey of U.S. colleges and universities about available resources for pursuing environmentally focused prevention. The typology is grounded in a social ecological framework, which recognizes that health-related behaviors are affected through multiple levels of influence: intrapersonal (individual) factors, interpersonal (group) processes, institutional factors, community factors and public policy. The survey on prevention resources and activities was mailed to senior administrators responsible for their school's institutional response to substance use problems. The study sample was an equal probability sample of 365 2- and 4-year U.S. campuses. The response rate was 76.9%. Recent case studies suggest the value of environmentally focused alcohol prevention approaches on campus, but more rigorous research is needed to establish their effectiveness. The administrators' survey showed that most U.S. colleges have not yet installed the basic infrastructure required for developing, implementing and evaluating environmental management strategies. The typology of campus-based prevention options can be used to categorize current efforts and to inform strategic planning of multilevel interventions. Additional colleges and universities should establish a permanent campus task force that reports directly to the president, participate actively in a campus-community coalition that seeks to change the availability of alcohol in the local community and join a state-level association that speaks out on state and federal policy issues.

    2018-06-01

    In recent years, the fight against healthcare corruption has intensified. Estimates from the European Healthcare Fraud and Corruption Network calculate an approximate €56 billion annual loss to Europe as a result of corruption. To promote understanding of the complexity and interconnection of corrupt activities, we aim to present healthcare-related corruption typologies of the European Union and European Healthcare Fraud and Corruption Network. We subsequently link them to the typology of individual and institutional corruption introduced by Dennis Thompson in the context of investigating misconduct of US Congressional members. According to Thompson, individual corruption is the personal gain of individuals performing duties within an institution in exchange for nurturing private interests, while institutional corruption pertains to the failure of the institution in directing the individual's behaviour towards the achievement of the institution's primary purpose because the institutional design promotes the pursuit of individual goals. Effective anti-corruption activities not only require the enactment of anti-corruption laws but also the monitoring and, where appropriate, revision of institutional frameworks to prevent the undermining of the primary purposes of health systems or institutions. To gain further understanding of the similarities and differences of the three typologies, prime examples of corrupt activities in the health sector in the European Union and USA (along with their potential remedies) are provided. Linking corruption cases to Thompson's typology revealed that many corrupt activities may show elements of both individual and institutional corruption because they are intertwined, partly overlap and may occur jointly. Hence, sanctioning individual actors only does not target the problem.

    As part of a larger program aiming at assessing transfer and effects of metals in food webs, this work studied the spatial distribution of Cd, Cr, Cu, Pb, and Zn in 101 sub-surface soils, systematically sampled (1 x 1 km regular grid) over a large area around Annaba, the fourth most-populated city of Algeria. Cd and Cr exhibited only one abnormally high value, with all other concentrations being close to pedogeological background. Some places in the centre of the city were polluted by Pb (up to 823 mg kg -1 ), probably due to aerial deposition from gasoline exhausts. Zn never exceeded regulatory limits over the whole sampling area. Cu was the only element for which a spatial autocorrelation occurred. A spatial interpolation by cokriging allowed the identification of agricultural activities as the main Cu pollution source. Our approach revealed various anthropogenic pollution sources, more efficiently for large-scale patterns than for local abnormalities. - A large-scale study of heavy metal concentrations in the area of Annaba (Algeria) shows Cu and Pb contamination in agricultural and urban soils, respectively

    2012-12-01

    The relationship of circadian typology with personality has been largely studied in adults, but there are few studies exploring such relationship in adolescents. Adolescence has been associated with a greater tendency to eveningness preference, sleeping problems, poorer academic achievement, earlier substance use, or risky behaviors, and it is suggested that this association might be mediated by personality factors. Given the relevance of identifying the behavioral outcomes of young evening types to detect and prevent health problems, the present study aimed to explore, for the first time, the relationship between sensation seeking and circadian typology in an adolescent sample of 688 students (51.45% boys) from 12 to 16 yrs old. They answered the Spanish versions of the Morningness-Eveningness Scale for Children (MESC) and the Junior Sensation Seeking Scale (J-SSS), which includes four subscales measuring Thrill and Adventure Seeking, Experience Seeking, Disinhibition, and Boredom Susceptibility. Analyses showed that boys obtained significantly higher scores than girls on J-SSS total score and all subscales except Boredom Susceptibility, whereas evening-type adolescents of both sexes scored significantly higher than neither types and than morning types on J-SSS total score. These results indicate that evening-type adolescents show a greater desire for varied, new, complex, and intense sensations, and they are ready for experiencing more risks than morning types. The implications of this study suggest the need of being aware of individual differences in the SS trait in evening-type adolescents, as well as taking into account the wide variety of behaviors associated with it, either prosocial or antisocial, to design better preventive health and academic programs.

    2017-12-01

    Full Text Available Le Jeu de la Hache displays a fighting-system with the pollaxe in armour, but the weapon is never described with precision, which leads to debates regarding its typology – cutting edge or hammer/raven’s beak? Through a semi-quantitative survey, we tried to offer an overview of current HEMA practice around this specific source, with special emphasis on the typological question. Despite the rather narrow scope of the inquiry, some trends emerge. Besides the various choices regarding terminology and sources, we can underline the variety of materials used for the simulators: rubber components («hammer» typology are leading, but wood and metal are also used, for both typologies. Advantages and disadvantages of each rely on the articulation of safety and realism dimensions, and the dangerousness inherent to this kind of weapon is largely highlighted. Even if most respondents declare not to be familiar with the typological debates amongst historians, it was usually mentioned to them during their practice. Only a minority has taken part in experiments in order to bring some elements of answer, but seldom in a systematic way. Therefore, a praxeological experimental approach could bring up new data, but is not devoid of difficulties, for instance the necessity of wearing armour.

  18. The New Oil-Related Issues in the Sahara

    Auge, Benjamin

    2011-01-01

    The Sahara is one of the last African regions to remain under-explored by oil companies. After the swift rise in crude oil prices about a decade ago, the land-locked nature of the terrain, the main hurdle standing in the way of exploration, had been overcome thanks to an exponential growth in sums set aside for exploration. The arrival on the scene of State enterprises, especially from China, also made profitability secondary to the pressing need to find new reserves. A study of the state of affairs in Mauritania, Mali, Niger, and Chad discloses how the situation differs from case to case. Some are already producing like Mauritania, albeit in small quantities, and Chad, which is the sole net exporter of the region, whereas Niger will begin producing in 2012 and Mali has not had a single well drilled for decades due to its haphazard choice of oil companies. The four States mentioned do not cooperate in any way in the oil sector even though this ought to be essential in a zone that has such special peculiarities in terms of climate, geography, and security as it is facing the threat of Al Qaeda in the Islamic Maghreb (AQMI) and the Tuareg

    The new forms of organization of healthcare services entail the development of new clinical practices that are grounded in collaboration. Despite recent advances in research on the subject of collaboration, there is still a need for a better understanding of collaborative processes and for conceptual tools to help healthcare professionals develop collaboration amongst themselves in complex systems. This study draws on D'Amour's structuration model of collaboration to analyze healthcare facilities offering perinatal services in four health regions in the province of Quebec. The objectives are to: 1) validate the indicators of the structuration model of collaboration; 2) evaluate interprofessional and interorganizational collaboration in four health regions; and 3) propose a typology of collaboration A multiple-case research strategy was used. The cases were the healthcare facilities that offer perinatal services in four health regions in the province of Quebec (Canada). The data were collected through 33 semi-structured interviews with healthcare managers and professionals working in the four regions. Written material was also analyzed. The data were subjected to a "mixed" inductive-deductive analysis conducted in two main stages: an internal analysis of each case followed by a cross-sectional analysis of all the cases. The collaboration indicators were shown to be valid, although some changes were made to three of them. Analysis of the data showed great variation in the level of collaboration between the cases and on each dimension. The results suggest a three-level typology of collaboration based on the ten indicators: active collaboration, developing collaboration and potential collaboration. The model and the typology make it possible to analyze collaboration and identify areas for improvement. Researchers can use the indicators to determine the intensity of collaboration and link it to clinical outcomes. Professionals and administrators can use the model to

Qualitative content analysis of transcripts was performed using the computer software ATLAS.ti 5. Healthcare professionals believe that religious beliefs do not affect living donation but say they have a negative impact on donation of cadaveric organs due to the existence of myths derived from the Islamic religion and lack of knowledge of the Algerian population about the positioning of religious leaders in relation to organ donation and transplantation. There is confusion among the Algerian population on the position of Islam around organ donation and transplantation, mainly to the detriment of the rate of cadaveric donation. Collaboration between the health sector and religious leaders to raise public awareness could improve the willingness of the population to donate organs after death. Copyright © 2016 SESPAS.

    The ecosystem services concept provides both an analytical and communicative tool to identify and quantify the link between human welfare and the environment, and thus to evaluate the ramifications of management interventions. Marine spatial planning (MSP) and Ecosystem-based Management (EBM) are a form of management intervention that has become increasingly popular and important globally. The ecosystem service concept is rarely applied in marine planning and management to date which we argue is due to the lack of a well-structured, systematic classification and assessment of marine ecosystem services. In this paper we not only develop such a typology but also provide guidance to select appropriate indicators for all relevant ecosystem services. We apply this marine-specific ecosystem service typology to MSP and EBM. We thus provide not only a novel theoretical construct but also show how the ecosystem services concept can be used in marine planning and management. Copyright © 2013 Elsevier Ltd.

    The ethnic minority population in developed countries is increasing over time. These groups are at higher risk of mental illness and demonstrate lower participation in research. Published evidence suggests that multiple factors like stigma, lack of trust, differences in explanatory models, logistical issues and lack of culturally aware researchers act as barriers to ethnic minority recruitment into mental health research. To reduce inequalities in participation, there is a need to devise innovative and culturally sensitive recruitment strategies. It is important that researchers share their experience of employing these strategies so that ethnic minority participation can be facilitated. We previously published a systematic review of barriers to recruiting ethnic minority participants into mental health research. The nine papers included in our prior review formed the basis for developing a typology of barriers to recruiting ethnic minorities into mental health research. This typology identified 33 barriers, described under five themes. We further extracted data on the strategies used to overcome these recruitment barriers, as described in the included studies. The strategies employed by the authors could be matched to all but two barriers (psychopathology/substance misuse and limited resource availability). There was evidence that multiple strategies were employed, and that these depended upon the population, clinical set-up and resources available. This typology of strategies to overcome barriers to recruiting ethnic minorities provides guidance on achieving higher rates of recruitment. It is important that researchers plan to deploy these strategies well in advance of initiating recruitment. Whilst adopting these strategies, the authors have not been able to quantify the positive impact of these strategies on recruitment. The typology should encourage researchers to employ these strategies in future research, refine them further and quantitatively evaluate their

    A typology of strategies related to the distribution channels used by Champagne makers is established. Champagne makers' operating profit depends on their distribution network, which affects selling prices. Based on a sample of 20 Champagne makers ("Maisons de Champagne"), economic and financial performance indicators for Champagne makers are analyzed with reference to the type of distribution channel.

    Concentrations of particulate matter less than 1  μm, 2.5  μm, 10 μm and their contents of heavy metals were investigated in two different stations, urban and roadside at Algiers (Algeria). Sampling was conducted during two years by a high volume samplers (HVS) equipped with a cascade impactor at four levels stage, for one year sampling. The characterization of the heavy metals associated to the particulate matter (PM) was carried out by X-Ray Fluorescence analysis (XRF). The annual average concentration of PM 1 , PM 2.5 and PM 10 in both stations were 18.24, 32.23 and 60.01 μg m -3 respectively. The PM 1 , PM 2.5 and PM 10 concentrations in roadside varied from 13.46 to 25.59 μg m -3 , 20.82-49.85 μg m -3 and 45.90-77.23 μg m -3 respectively. However in the urban station, the PM 1 , PM 2.5 and PM 10 concentrations varied from 10.45 to 26.24 μg m -3 , 18.53-47.58 μg m -3 and 43.8-91.62 μg m -3 . The heavy metals associated to the PM were confirmed by Scanning Electron Microscopy-Energy Dispersive X-Ray analyses (SEM-EDX). The different spots of PM 2.5 analysis by SEM-EDX shows the presence of nineteen elements with anthropogenic and natural origins, within the heavy metal detected, the lead was found with maximum of 5% (weight percent). In order to determine the source contributions of PM levels at the two sampling sites sampling, principal compound analysis (PCA) was applied to the collected data. Statistical analysis confirmed anthropogenic source with traffic being a significant source and high contribution of natural emissions. At both sites, the PM 2.5 /PM 10 ratio is lower than that usually recorded in developed countries. The study of the back-trajectories of the air masses starting from Sahara shows that desert dust influences the concentration and the composition of the PM measured in Algiers.

    There is a long tradition within qualitative research of theory being central and of critical importance. Qualitative research theory often equates with the methodologies used but this is a complex relationship, plagued by lack of consensus among scholars regarding how theory and methodology are related. This article furthers the debates on how theories are used in qualitative research, how they might influence a study and how they are articulated in publications. The aim is to provide a framework through which the relationship between theory and qualitative research can be understood. We propose a five-point typology on the levels of theoretical visibility, testing this against a range of published research from five key international health, medicine and social science journals. The typology captures a range of visibility--from seemingly absent through to highly visible and applied throughout. There was a clear gradient in this assessment--only a minority appeared to use theory consistently throughout a study. We outline several challenges to consistently applying theory in qualitative research and suggest potential solutions. This article is based on the argument that lack of theory in qualitative research undermines its quality. The typology is offered to assist researchers in applying theory in their own research and critiquing its use in the work of others. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Aim: The present study was undertaken to know the seroprevalence of Mycoplasma synoviae (MS and Mycoplasma gallisepticum (MG in broiler and layer chickens in the area of Batna, eastern Algeria. This investigation was conducted during the period from 2008 to 2011. Materials and Methods: A total of 505 sera samples were collected and tested by serum plate agglutination (SPA test using Mycoplasma gallisepticum and Mycoplasma synoviae antigens (Soleil Diagnostic to detect the presence of antibodies against MS and MG. Results: The overall prevalence of MS and MG infection in the 27 flocks visited in this investigation were recorded as 66.33% and 69.90% respectively. Seroprevalence of MG infection was found significantly (p<0.05 higher during winter season (61.48% than in summer (47.74% while MS infection is more dominant in summer (91.25% against 46.69%. Again this was recorded in different age groups, with significantly higher occurrence in young compared to adult with 85.14% in layer hens and 90.73% in broiler chickens. On the other hand, the seroprevalence of MG and MS infection was found little (p>0.05 higher in large flocks (76.97% in comparison to small flocks (63.63%. The highest prevalence (76.59% of mycoplasmal infection in layer hens was found in Lohman strain. Conclusion: It has been found that MG and MS infections are still important disease problems in poultry farms in Algeria. [Vet World 2012; 5(12.000: 709-712

    A cross-sectional study using a tested questionnaire was carried out across Algeria between January and June 2014. Our investigation demonstrated that of the 150 flocks visited, 21 were positive for sheep pox and goat pox (SPGP) with an overall flock prevalence of 14% (95% CI 11.08-16.92%) suggesting that SPGP is endemic in Algeria. Our results showed also that the disease appears only in sheep and no case affecting goats has been reported. For the risk factor analysis, univariate analysis of variables followed by a multiple logistic regression identified steppe region (OR = 1.81, 95% CI 0.87-2.57; P = 0.037), large flocks (OR = 2. 19, 95% CI 1.02-3.36; P = 0.027), and transhumance (OR = 3.98, 95% CI 2.59-5.34; P = 0.021) as risk factors in the spread of the disease. Furthermore, our study revealed that the use of vaccination as preventive measures in the selected flocks decreased the odds for SPGP positivity by 5.78 (95% CI 2.22-9.34; P < 0.001) times compared to non vaccinated flocks. In conclusion, our findings documented an evidence of a widespread distribution and endemic establishment of the SPGP in Algerian sheep population despite the annual vaccination program. Consequently, the vaccination must cover all the Algerian sheep population to improve animal welfare and reduce economic losses associated with outbreak episodes.

    Full Text Available The author investigates how consumer search behavior typology affects the relationship between customer satisfaction and behavioral intentions. The results show that the type of consumer as defined by whether and how they search for information (passive, rational-active, relational-dependent perceive different levels of satisfaction and performs differently on satisfaction-behavioral intentions linkages. Relational-dependent and rational-active consumers are found to perceive higher satisfaction levels, and to express stronger intentions to engage in positive behavioral intentions than passive consumers. The identification of satisfaction and behavioral intentions within each search type allows managers to satisfy their consumers; hence, the company will obtain higher profit.Keywords: consumer behavior typology, satisfaction, behavioral intentions

    Full Text Available The aim of this paper was to study the elderly representations in Romanian video advertising in order to identify a typology corresponding to these representations. The research method that I used was the content analysis with a dominant qualitative approach, but also including quantification elements. The commercials that I selected for my analysis promoted health products, banking and insurances and fast moving consumers’ goods (FMCG. The identified typology is composed of five types of elderly representations: Super-Grandparents, Seclusive Elderly, Sick Elderly, Funny Elderly, and High-Tech Elderly. The representation types and their stereotypical content varied depending on the type of product/service that was promoted and on the public addressed by commercials.

    Algeria is among the most water-stressed countries in the world. Because of its climatic conditions, irrigation is essential for agricultural production. Water prices paid by farmers in public irrigation districts are very low and do not cover the operation and maintenance (O&M) costs of the irrigated perimeters, thus leading to the deterioration of these infrastructures. The objective of this paper is to analyse whether farmer’s in the West Mitidja irrigation district in northern Algeria would be willing to pay more for surface water in order to maintain the water supply service in its current conditions. We estimated farmers’ willingness to pay (WTP) for water using data from a dichotomous choice contingent valuation survey to 112 randomly selected farmers. Farmers’ responses were modelled using logistic regression techniques. We also analysed which technical, structural, social and economic characteristics of farms and farmers explain the differences in WTP. Our results showed that nearly 80% of the surveyed farmers are willing to pay an extra price for irrigation water. The average WTP was 64% greater than the price currently paid by farmers, suggesting some scope for improving the financial resources of the Mitidja irrigated perimeter, but insufficient to cover all O&M costs. Some of the key identified factors that affect WTP for surface water relate to farm ownership, access to groundwater resources, cropping patterns, farmers’ agricultural training and risk exposure.

    Tinea capitis are common in Algeria and are a frequent reason for consultation. This mycosis affects children and rarely adults. This is a retrospective study over a period of 20 years from 1995 to 2015 at the mycology laboratory of the Pasteur institute of Algeria. Observe the evolution of these tinea over the years, to study the epidemiological aspects and identify the responsible agents. This study concerned patients of all ages and sexes living in the region of Algiers and the environs, consultant for various scalp lesions. For each patient, a completed information sheet is developed in insisting on the presence of animals and people with similar lesions. For each sampling, direct examination and culture on Sabouraud medium and antibiotics are utilized. The cultures are put at T° 27 to 28°C and controlled regularly during 3 to 4 weeks. A total of 2664 samples were collected, 892 examinations were positive corresponding to a frequency of 33.48%. The age group 0-10 years is the most affected 710 cases (79.60%), with a slight predominance for male sex 502 cases (56.27%) and 390 cases (43.72%) for female sex. Eight hundred and fifty-five dermatophytes strains were isolated. Among the species found, Trichophyton violaceum is the most species isolated (59.41%), followed by Microsporum canis to 35.08%. In our series, the number of cases of tinea has increased slightly over the years, the rate of 26% in 2001 has progressed to 41.02% in 2015. From 1995 to 2011, T. violaceum was the predominant species, but from the year 2011 we see an increase of M. canis and decreased of T. violaceum. Tinea capitis remains frequent in Algeria and affects preferentially the children. T. violaceum and M. canis dominate the dermatophytic flora. Tinea trichophytic anthropophiles have progressively decreased in favor of tinea microsporic zoophiles who saw their number increased. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The groundwater resources in the Northern Sahara are represented by two superimposed major aquifer systems: the Intercalary Continental (CI) and the Terminal Complex (CT). The waters of these aquifers pose serious physical and chemical quality problems; they are highly mineralized and very hard. The present work aims to describe the water's geochemical evolution of sand groundwater (Mio-Pliocene) of the Terminal Complex in the area of Djamaa, by the research of the relationship between water's chemical composition and lithology of aquifer formations through. The results obtained show that the water's chemistry is essentially governed by the dissolution of evaporate formations, which gives to, waters an excessive mineralization expressed by high concentrations of sulfates, chlorides and sodium.

    Cities are formed from historical layers. When different periods are examined, it is possible to reach out the information about the relation with the built environment created with the society’s owned culture and the location where the built environment is through these historical layers. Cultural and natural values owned by the city, shape the city identity. To have a city identity, it is necessary to provide the continuity of these values and to protect moral and material values which transfer messages of city’s past to its future. City identities in the World and in Turkey have been gradually disappearing because of the immigrations which are the results of globalization and industrialization. This situation creates the feeling of “Alienation” in the people who live in the city. Also in Kocaeli, which lost its’ agricultural city feature owned until 1960s and whose industrial city feature has come into prominence for 50 years, same problems can be observed. Traditional houses are formed depending on the society’s different cultural values. Some places in the traditional houses have disappeared completely or have become useless time-dependently. That’s why it is very important to reveal the local similarities. Thanks to the datum gathered by analysing with the Typology method, the historical traces will be the guiding light of continuing structuring and future. On this purpose, Kapanca Street has been chosen as study area. This street is one of the historical layers of Kocaeli city and which is one of the rare places still protecting the authenticity. There are 10 traditional registered houses belonging to the late Ottoman Period in the end of 19th century and the beginning of 20th century on this street. The values of Kapanca Street, which constitutes an important place in the historical identity of Kocaeli and has a historical background more than a century are thought to be in need of being recorded to provide the cultural continuity and to be

    Full Text Available Scorpion stings are a public health problem in the Maghreb region. In Algeria, epidemiological data were collected over the past twenty years by the Algerian health authorities. This study is an analysis of morbidity and mortality data collected from 2001 to 2010. Annual incidence and mortality due to scorpion envenoming were 152 ± 3.6 stings and 0.236 ± 0.041 deaths per 100,000 people (95% CI, respectively. The risk of being stung by a scorpion was dramatically higher in southern areas and central highlands due to environmental conditions. Incidence of envenoming was especially higher in the adult population, and among young males. In contrast, mortality was significantly higher among children under 15 years, particularly ages 1-4. Upper limbs were more often affected than lower limbs. Most stings occurred at night, indoors and during the summer. Data collected since 2001 showed a reduction of mortality by nearly 50%, suggesting that the medical care defined by the national anti-scorpion project is bearing fruit.
