Full Text Available Este artículo aborda el campo del manejo de los recursos hídricos y propone un esquema de análisis para estudiar las relaciones entre las instituciones y las prácticas de los actores afectados por las acciones de tales instituciones. Avanza después, en forma preliminar y descriptiva, sobre la exploración de algunas de las categorías presentadas en el esquema propuesto en un caso concreto (Mendoza, Argentina. Reconocemos una doble dinámica de funcionamiento del régimen hídrico: una entre la autoridad hídrica y los grandes y poderosos actores vitícolas y otra entre un conjunto de entidades satélites no hídricas y pequeños productores. Esto lleva a que desde la política hídrica se reproduzca un modelo de producción que claramente beneficia a un sector a costa de otro.   HYDROLOGIC ORDER: PRACTICES AND INSTITUTIONS IN MENDOZA, ARGENTINA This article addresses the territory of water resource management and proposes an analytical framework to study the inter-institutional relationships and practices of the stakeholders affected by the actions taken by those institutions. It explores in a preliminary and descriptive form some of the categories presented in the framework proposed for the specific case of Mendoza, Argentina. It identifies a double working dynamic in the hydrologic regime: one between the hydrologic authorities and large-scale and powerful stakeholders of the wine industry and another dynamic between a series of non-hydrologic satellite entities and small-scale producers. This leads to a hydrologic policy that reproduces a production model that clearly benefits one sector at the expense of another.

Water in the Mendoza, Argentina, food processing industry: water requirements and reuse potential of industrial effluents in agriculture

Alicia Elena Duek

2016-04-01

Full Text Available This paper estimates the volume of water used by the Mendoza food processing industry considering different water efficiency scenarios. The potential for using food processing industry effluents for irrigation is also assessed. The methodology relies upon information collected from interviews with qualified informants from different organizations and food-processing plants in Mendoza selected from a targeted sample. Scenarios were developed using local and international secondary information sources. The results show that food processing plants in Mendoza use 19.65 hm3 of water per year; efficient water management practices would make it possible to reduce water use by 64%, i.e., to 7.11 hm3. At present, 70% of the water is used by the fruit and vegetable processing industry, 16% by wineries, 8% by mineral water bottling plants, and the remaining 6% by olive oil, beer and soft drink plants. The volume of effluents from the food processing plants in Mendoza has been estimated at 16.27 hm3 per year. Despite the seasonal variations of these effluents, and the high sodium concentration and electrical conductivity of some of them, it is possible to use them for irrigation purposes. However, because of these variables and their environmental impact, land treatment is required.

With the objective of to get to forecast and operative determinations tool to seeding of hailstorm in the damage mitigations job that produces its precipitation in Mendoza (Argentina), we developed to software based in on surface and 500 mb. level atmospherics variable. We had used on surface dates because in this level exist to big amount of information, practically it is possible to get its measures continuously; in addition it is the level that data of damages are registered that the hail precipitation produces. The decision to use the level of 500 mb, it must to that it is the height in which the upset one of the air circulation takes place from the Pacific to Mendoza, who produces important changes and instability in the atmosphere of Mendoza, these data were obtained from the radiosonde of Santo Domingo in Santiago (Chile) and El Plumerillo (Mendoza). In the program is integrated the different indices and models obtained in ours works from investigation on the subject of last the five years. Since the October of 2004 to April of 2009 the values have been taken from the variables mentioned every day, hourly during the fight campaigns antihail (October-April). The results have integrated in the program INCAS, whom it is due to enter the surface variables: Temperature in °C, the dew point in °C, the atmospheric pressure in mb., the index of ultraviolet solar radiation, the direction and wind speed; whereas the variables of the level of 500 are due to introduce mb: height of the level of 500 mb in meters, temperature of the level in °C, the direction and wind speed to that height. From the process of these variables the type of convective process is obtained like exit of the program , that is more probable that it appears in Mendoza for these atmospheric conditions; the thresholds that trigger to the stormy processes and their possible severity. This year software was validated in his first version, obtaining itself very good results.

Full Text Available A comparative study of elements deposited on tree bark was carried out for urban and periurban areas of two of the most important cities in Argentina. The content of Fe, Mg, Al, Mn, Zn, Pb, Ba, Cr, Hg, Cu, Ni, Cd and Sb was determined by inductively coupled plasma atomic emission spectrometry (ICP-OES in Morus alba tree bark collected in the cities of Buenos Aires and Mendoza. The main air pollutants detected in the Buenos Aires urban area were Ba, Cr, Cu and Ni and indicate significative difference from the Mendoza urban and periurban areas. Significantly, higher concentrations of Zn, Ba, Cr and Cu were recorded in the periurban area of the city of Buenos Aires than in Mendoza. Bark samples were strongly influenced by dust and show Al, Fe, Mg and other element accumulations that indicate that soil particles were carried out by wind. Elements like Ba and Zn, commonly linked to traffic emissions, showed the highest concentrations in the Buenos Aires metropolitan area, possibly due to more intensive vehicular traffic. Our results indicated that intensity of vehicular traffic and not city structure is responsible for air pollution.Um estudo comparativo dos elementos depositados nas cascas das árvores foi realizado nas áreas urbanas e na periferia de duas cidades das mais importantes da Argentina.

Full Text Available Una nueva especie del complejo Liolaemus darwinii es descrita para el centro de la provincia de Mendoza, Argentina. Se parece más a L. olongasta y L. laurenti en que los machos adultos tienen pigmento negro en el pliegue antehumeral y manchas escapulares que no son agrandadas. Difiere de estas especies en tener un cuerpo adulto menor, un número mayor de escamas en la mitad del cuerpo, una cola más corta y un mayor número de poros precloacales en machos, y un patrón ventral distinto en machos adultos. En el norte de su distribución se encuentra L. darwinii en el norte de la provincia de Mendoza y en la provincia de San Luis, y en el sur en el oeste de la provincia de La Pampa, en el noroeste de la provincia de Neuquén y en la provincia de Río Negro, pero se desconoce si estas poblaciones del norte y del sur de L. darwtnii están separadas por la distribución de la nueva especie. Análisis cladísticos basados en comportamiento, morfología y secuencias de DNA muestran filogenias conflictivas, pero concuerdan en que la nueva especie es un miembro del grupo boulengeri, con afinidades más cercanas a L. darwinii, L. olongasta y L. laurenti. A new species,of the Liolaemus darwinii complex is described from central Mendoza Province, Argentina. It most closely resembles L. olongasta and L. laurenti in that adult males have black pigment in the antehumeral fold and scapular spots that are not enlarged. It differs from these species in having a smaller adult body size, a higher number of midbody scales, a shorter tail, more precloacal pores in males, and a different adult male ventral body pattern. Its range is bordered by L. darwinii on the north in northern Mendoza and San Luis provinces, and on the south in western La Pampa and northwestern Neuquén and Río Negro provinces, but it is unknown whether these northern and southern populations of L. darwinii are separated by the range of the new species.

Full Text Available The aim of this work was to study the influence of sucrose and glucose, amino acids and BAP (6-Benzylaminopurine levels on in vitro shoot regeneration of fox grape cv. Bordô and grapevine cv. Chardonnay. The nodal segments from micropropagated material were used as explants and half-strength MS medium as the basal medium. Sucrose and glucose at 15, 30 and 45 g.L-1 were tested as a carbon source and the supplementation of adenine, asparagine, alanine, glycine, cysteine, glutamine, arginine was tested at 40 g.L-1. The BAP levels (1 and 5 μM in solid and double-phase media were evaluated and compared with a control medium without BAP. Bordô had best in vitro growth than Chardonnay. Sucrose was a better carbohydrate source than glucose for both the cultivars. Bordô and Chardonnay had different amino acid preferences for some parameters. In conclusion, for in vitro shoot regeneration from the nodal segments, culture on solid medium with 5 μM BAP, 15 g.L-1 sucrose for Bordô and 45 g.L-1 sucrose for Chardonnay showed better results. Similarly, the supplementation of 40 g.L-1 arginine for Bordô and 40 g.L-1 arginine or glycine for Chardonnay showed better results.

Se determinó el número de generaciones anuales y se estudiaron las fluctuaciones poblacionales asociadas a la integral térmica para la especie en esta región. D. perniciosus presenta dos generaciones superpuestas al ciclo del cultivo, mientras que las ninfas (N1 y N2 de la tercera generación se desarrollan solamente hasta el final de la temporada estival y pasan al estado de quiescencia, en el que permanecen durante el invierno. El desarrollo de D. perniciosus en esta zona coincide con el de esta especie en la zona frutícola del centro de Chile en cuanto al número de generaciones y al periodo de quiescencia invernal. La población quiescente en Chile está integrada predominantemente por ninfas del primer estadio (N1, mientras que en San Carlos, Mendoza, la población quiescente está integrada principalmente por ninfas del segundo estadio (N2. La similitudes entre ambas poblaciones se deben, probablemente, a las coincidencias en latitud, clima y especie hospedera. El impacto económico de D. perniciosus en la zona de estudio tiene mayor relevancia durante los meses de diciembre y enero, cuando se observa una alta incidencia de daños en los frutos y las hojas; este es el momento decisivo para implementar medidas de control fitosanitario.

Five species of Urocleidoides (one new) and two new species of Constrictoanchoratus n. gen. are described in this study. All were collected from the gills of Hoplias malabaricus (Characiformes: Erythrinidae) captured in six localities of coastal rivers of the north-eastern sector the State of Pará (Oriental Amazon): Urocleidoides brasiliensis Rosim, Mendoza-Franco & Luque, 2011; Urocleidoides bulbophallus n. sp.; Urocleidoides cuiabai Rosim, Mendoza-Franco & Luque, 2011; Urocleidoides eremitus Kritsky, Thatcher & Boeger, 1986; Urocleidoides malabaricusi Rosim, Mendoza-Franco & Luque, 2011; Constrictoanchoratus lemmyi n. gen. n. sp.; and Constrictoanchoratus ptilonophallus n. gen. n. sp. This is the first reported occurrence of the four previously described species of Urocleidoides parasitizing H. malabaricus from streams in the Oriental Amazon Basin. The analysis of voucher specimens of U. eremitus parasitizing the gills of H. malabaricus from the Upper Paraná River floodplain in the limits of States of Paraná and Mato Grosso do Sul, Brazil, indicates that these specimens are members of a new species of Urocleidoides, described here as Urocleidoides paranae n. sp. Constrictoanchoratus n. gen. is proposed for the species with a male copulatory organ sclerotized, coiled, clockwise; ventral anchor with elongate superficial root, inconspicuous deep root; dorsal anchor with inconspicuous roots, and a constriction at the intersection between the shaft and the point. The host-parasite diversity scenario and host specificity of the species of Constrictoanchoratus n. gen. and Urocleidoides from the gills of H. malabaricus are also discussed in this study.

Paleozoogeography of the Wine Mouse (Akodon oenos & Late Holocene Paleoenvironments in South-Central Mendoza, Argentina

Full Text Available Cranial remains of the wine mouse (Akodon oenos are documented from an archaeological site in south-central Mendoza, Argentina (Agua de La Mula, 35º22' S, 68º15' W, which dates to the end of the late Holocene (1610 ± 60; 1260 ± 60; 1000 ± 50 C14 yr B.P.. The taxonomic status of this small rodent is currently being assessed, but these remains represent the first fossil record for the morphotaxon A. oenos. The species’ present distribution is restricted to a few records from Mendoza province. Analysis of the remains supports paleoenvironmental reconstruction using the small mammal assemblage recovered from this site. From the late Holocene into modernity temperature decreased and winter precipitation increased, resulting in advance of Patagonian steppe grading with altitude into Monte desert. Holocene climatic conditions may explain the relatively late human occupation of ecologically marginal environments in this region, which probably favored effective human occupation of the Payunia region at sites such as Agua de La Mula between 1600 and 1000 years B.P.

Knowledge of the chemical composition of wine and its association with the grape variety/cultivar is of paramount importance in oenology and a necessary tool for marketing. Phenolic compounds are very important quality parameters of wines because of their impact on colour, taste and health properties. The aim of the present work was to study and describe the non-flavonoid and flavonoid composition of wines from the principal red grape varieties cultivated in Mendoza (Argentina). Sixty phenolic compounds, including phenolic acids/derivatives, stilbenes, anthocyanins, flavanols, flavonols and dihydroflavonols, were identified and quantified using high-performance liquid chromatography with diode array detection coupled with electrospray ionisation mass spectrometry (HPLC-DAD/ESI-MS). Marked quantitative differences could be seen in the phenolic profile among varieties, especially in stilbenes, acylated anthocyanins and other flavonoids. The polyphenolic content of Malbec wines was higher compared with the other red varieties. Dihydroflavonols represent a significant finding from the chemotaxonomic point of view, especially for Malbec variety. This is the first report on the individual phenolic composition of red wines from Mendoza (Argentina) and suggests that anthocyanins, flavanols and phenolic acids exert a great influence on cultivar-based differentiation.

We report on our experiment to measure h/M, the ratio of the Planck constant to the mass of Cs atoms, and thereby the fine-structure constant. The target accuracy is 1 part per billion or better. We focus on two recent milestones: (i) The first realization of atom interferometers based on light-pulse beam splitters that transfer the momentum of up to 12 photon pairs, which increases the useful signal (matter wave phase shift) by a factor of 144 compared to the beam splitters used in the best present atom interferometers. Moreover, they lead to a cancellation of important systematic effects. (ii) The first realization of a simultaneous pair of conjugate Ramsey-Borde interferometers. In these, the relative sign of the inertial term is reversed so that it can be cancelled. Simultaneous operation means that this holds for a time-dependent inertial term (vibrations) too, which promises a substantial improvement in the signal to noise ratio

Evaluation and design of the uranium project “Tigre I – La Terraza”, Sierra Pintada, Mendoza, Argentina

International Nuclear Information System (INIS)

Mansilla, M.; Dieguez, S.

2014-01-01

The Sierra Pintada uranium district in Mendoza Province, Argentina, was discovered by airborne survey. This deposit is associated with a volcanic caldera and occurs in the Lower Permian volcaniclastic sediments of the Cochico Group, in which aeolian and fluvial sandstones, inter-bedded with ignimbrites, were reworked by pyroclastic flows. The origin of the mineralization is interpreted as a product of the leaching of the inter-bedded rhyolitic tuff. The mineralization is lenticular and nearly concordant with the bedding. The deposit has been affected by a complex fault system, which is responsible for mineralization and disposition via spatial displacement. The primary uranium minerals are uraninite, brannerite and coffinite. Uranophane and low liebigite uranium are the products of the oxidative alteration of primary minerals. This study involves the technical and economical evaluation of the open pit uranium mining project Tigre I – La Terraza in Mendoza, Argentina, at prefeasibility level. Its development includes geological modeling through economic evaluation, and the incorporation of different mining-specific software.

Identificación de patrones espaciales del borde urbano mediante mapas Auto-Organizados de la centralidad de la red viaria.

Full Text Available La caracterización morfológica del borde urbano es un ejercicio que reviste un interés especial porque, por una parte, ayuda a entender los crecimientos urbanos que tienen lugar en las zonas periféricas y, por otra, permite descifrar las claves de las relaciones de continuidad o discontinuidad que existen entre la ciudad y su entorno. En este contexto, son muchos los enfoques desde el análisis. En este artículo, se exploran en concreto las posibilidades que ofrece la utilización de mapas auto-organizados, elaborados a partir de los resultados de la aplicación de medidas de centralidad de la red viaria mixta que forman los sistemas de calles, los viarios metropolitanos y los caminos agrarios. La aplicación de diferentes medidas de centralidad en una red viaria mixta, supone en sí un ejercicio innovador, ya que, normalmente, los análisis de centralidad se aplican en el ámbito más puramente intraurbanos. La base espacial de los perfiles obtenidos en las series se puede comparar con la naturaleza del propio borde. La Metodología propuesta se ha testeado en la ciudad de Granada (España, específicamente, sobre el borde de contacto de la ciudad con el entorno de la Vega de Granada, un paisaje agrario singular ligado al Río Genil.

The use of massive SIT for the control of the Medfly, Ceratitis capitata (Wied.), strain SEIB 6-96, in Mendoza, Argentina

The increasing demand for fresh fruits has led to the development of new techniques in farming and in harvest and postharvest areas. Special care has been taken to ensure that the use of pesticides reconciles pest control with a low impact on the environment and human health. The presence of pests of economic importance, among them, the Medfly (Ceratitis capitata Weid.), led to the search for alternative techniques of control. The Medfly was first recorded in the United States in 1901, and in Argentina in 1934. The use of the sterile insect technique (SIT) began to develop around 1950. Improvement in the technique has produced promising results world-wide, especially in the breeding of sexing strains, which allows the release of sterile males only. The National Service of Agrifood Quality and Protection (SENASA) of Argentina, coordinates the National Program of Control and Eradication of Fruit Flies (PROCEM). PROCEM has divided Argentina into five different regions. This is according to quarantine regulations, and control and eradication activities to be undertaken. Actually, the Mendoza and San Juan provinces, and the Patagonia Region, have adhered to PROCEM. They have ongoing regional programmes in their respective areas. Mendoza and the Central Valleys of San Juan (Tulum, Ullum and Zonda) are included in the New Cuyo Region, Phase I, where the main objectives are: eradication of the Medfly; verification of the quarantine status; creation of a Medfly free area and exports to Medfly free markets. SIT is the main technique used in Mendoza for Medfly eradication. The Institute of Quality and Protection of Mendoza (ISCAMen) is in charge of the programme in the Province of Mendoza. Mendoza policies for Medfly eradication and the use of SIT, are based on: a growing area of 290,000 ha of vegetable and fruits (vineyards, stone, pome and nut orchards) of high quality, with favourable agroecological conditions and geographical isolation, exports of fresh fruits for the

Full Text Available Achieving the paradigm of sustainable urban mobility requires institutional capacities, appropriate policies and a regulatory framework that contains them. This work aims to contribute to the knowledge of the regulation of urban mobility in the metropolitan area of Mendoza. To this end, the current mobility regulations are assessed through indicators that are classified into three key areas: institutional and political organization, urban system and financial setup. The purpose is to account for the existence, or not, of regulatory capacities contained in the paradigm of sustainable mobility. Among the results, the absence of a policy of sustainable urban mobility is noteworthy, as well as the lack of sectorial coordination. Also of note is the absence of coordination between the urban planning system and the public transport provision. Lastly, in the financial sector, the results point to a promotion of sustainable transport modes but without such an explicit purpose.

El Infiernillo porphyry copper and Mo deposit, in southern Mendoza, Argentina is hosted by ignimbrites of the Cochico Group (lower Permian). The alteration zone consists of a small central quartz neck with appreciable hematite surrounded by an intense quartz-injected zone with local pervasive potassic alteration. Outwards, there is a well-developed phyllic halo with intense bleaching which consists of pervasive and vein-type silicification, sericitization and pyritization. In the outer part of the alteration zone, small polymetallic veins with pyrite, arsenopyrite, galena and minor, chalcopyrite, sphalerite and electrum in quartz gangue crop out. New field, petro-mineralogic and geochemical data confirmed that the host rocks are equivalent to the dacitic and rhyodacitic ignimbrites of the Toba Vieja Gorda Member (Yacimiento Los Reyunos Formation, Cochico Group)

Full Text Available In the frame of C-BORD project (H2020 program of the EU, a Rapidly relocatable Tagged Neutron Inspection System (RRTNIS is being developed to non-intrusively detect explosives, chemical threats, and other illicit goods in cargo containers. Material identification is performed through gamma spectroscopy, using twenty NaI detectors and four LaBr3 detectors, to determine the different elements composing the inspected item from their specific gamma signatures induced by fast neutrons. This is performed using an unfolding algorithm to decompose the energy spectrum of a suspect item, selected by X-ray radiography and on which the RRTNIS inspection is focused, on a database of pure element gamma signatures. This paper reports on simulated signatures for the NaI and LaBr3 detectors, constructed using the MCNP6 code. First experimental spectra of a few elements of interest are also presented.

García de Andrés, Carlos

2001-08-01

Full Text Available The prior austenite grain size (PAGS exerts an important influence on the microstructures forged by continuous cooling in the steel and on their mechanical properties. Since microalloyed steels have received considerable attention in the last years and enormous difficulties have been repetitively to reveal the austenite grain boundaries in these steels, this work analyzes the different techniques effective in that sense, which enable thus an accurate determination of the PAGS. This paper presents results obtained applying different conventional techniques such us chemical etching of quenched microstructures, the application of thermal cycles that enable the formation of phases around the prior austenite grain boundaries or oxidation etching which reveals the austenite grain boundaries by the preferential accumulation of oxides. Finally, an innovative and effective technique to reveal the prior austenite grain boundaries is presented. This technique is based on the preferential transfer of matter from the grain boundaries to the surrounding austenite by complicated mechanisms such as evaporation-condensation and volume and surface diffusion of atoms.

Se seleccionaron dos parches de bosque por cada tipo de borde, para analizar 13 criterios entre fisiográficos, microclimáticos, estructura y composición de la vegetación. Tres de los criterios (pendiente, forma y área del parche son poco determinantes del tipo de hábitat de borde, los demás están estrechamente relacionados con las condiciones del microambiente y éste a su vez con la estructura y composición de la vegetación, confiriendo características particulares a cada hábitat de borde. El borde paramizado muestra la menor capacidad de autorregulación ambiental estando más expuesto a la fluctuación en estas variables, debido a su exposición directa a la acción del viento y a la pérdida de los estratos arbóreos más altos (entre 10 y 15 m, por lo que requiere la mayor intervención para su restauración. El borde de chusque es el más resguardado al actuar esta especie como una barrera protectora, que sin embargo debe ser controlada para promover la expansión del bosque como habita en el borde antiguo, el cual presenta una capacidad reguladora intermedia entre los otros dos.Characterization of High Andean forest edges and implications for their ecological restoration (Colombia.

A Fast Fourier Transform was used to decompose the series into dynamic parameters: mean NDVI, amplitudes (maximum NDVI variability and phases (time from start of cycle to maximum NDVI for different time periods. A classification is made based on those parameters with larger information content (inter- and intra-annual variability, achieving a map of 18 areas of phenological behaviour. This

Full Text Available La provincia de Mendoza posee una rica fauna de lagartos pertenecientes a las familias Leiosauridae, Liolaemidae, Teiidae, Scincidae y Gekkonidae. Algunos son propios del Monte, Puna, Payunia o región andina, mientras que otros poseen una amplia distribución, ocupando dos o más ecosistemas. El objetivo de este trabajo fue actualizar la lista lacertofaunística de la provincia y determinar las áreas de mayor riqueza de especies en relación a estos cuatro tipos de ecosistemas. Se utilizaron datos de procedencia de 43 especies de lagartos a partir de colecciones herpetológicas y de bibliografía. Las localidades fueron georreferenciadas y mapeadas. Una primera estimación de las áreas de mayor riqueza fue realizada sobre la base de las distribuciones de acuerdo a los puntos de colecta. En un segundo análisis, se generaron modelos predictivos de distribución utilizan-do 26 variables ambientales. Estas áreas potenciales fueron superpuestas a fin de obtener el número de especies en cuadrículas de 4,6 km x 4,6 km. Los resultados de ambos métodos indican que la mayor riqueza de especies se encuentra en la Payunia, probablemente en relación a la mayor heterogeneidad ambiental de la zona, ya que es considerada un área ecotonal entre la región fitogeográfica de la Patagonia y el Monte. Un análisis de similitud (Índice de Morisita demuestra que la similitud entre ecosistemas en cuanto a la composición de especies es baja, conformándose dos grupos: el Monte y Patagonia por un lado, y el ecosistema Andino y Puneño por otro.

Full Text Available Este artículo presenta las diferentes formas de inserción laboral de trabajadores jóvenes en el Valle de Uco, en la provincia de Mendoza. Durante las últimas décadas, el Valle de Uco basó su patrón de desarrollo agrícola en un modelo intensivo y empresarial de sus tres principales cultivos: los viñedos, los frutales y las hortalizas. En la actualidad, atraviesa un proceso de profunda reconversión productiva, orientada mayoritariamente hacia el mercado externo, que entre otras consecuencias pasó a modificar el funcionamiento del mercado de trabajo local. En este artículo, se contemplan las diferentes situaciones que llevan al ingreso laboral de los jóvenes en este contexto, según el momento etáreo que atraviesen. Se analiza la relación que este proceso guarda con el tamaño y la estructura de las familias y la situación socio-económica del hogar al que pertenecen. También, se examina el vínculo entre las características de los hogares y la forma de inserción de los jóvenes en el mercado de trabajo, de acuerdo al tipo de ocupación en la que se desempeñan y al destino que le dan a sus ingresos. A partir de la realización de entrevistas en profundidad a trabajadores jóvenes y a informantes clave se pudo dar cuenta de las preferencias de los jóvenes con respecto a distintos tipos de trabajos, con particular énfasis en ciertos trabajos agrícolas y, también en relación a su futuro laboral.This article deals with the different ways that young workers in the Uco Valley, at the province of Mendoza, enter to the agrarian local labour market.

The Medical Vocabulario terminológico of Manuel Hurtado de Mendoza

2012-12-01

Full Text Available From the early nineteenth century, Spanish physicians started to sense a «threat» to the language of medicine which they used, due in part to the large number of foreign terms they were forced to import from other languages, particularly French. Many voices emerged to denounce this situation and propose potential solutions such as those which would be derived from the creation of a terminological dictionary which would fix precise meanings for medical terms. It was Manuel Hurtado de Mendoza who eventually dared to take on this task and develop the first modern terminological dictionary of medicine in Spanish. The intention of this paper is to present from a philological viewpoint the process by which a lexicographical work that deserves to be better known and used in studies on historical lexicography came to be constructed.

There are different behaviors in each stratum according to each growing zone. It has been observed that in all “oasis” smaller is the holding, higher is the rate of shrinkage. On the other hand the bigger sizes grow and the acreage concentration of these units has increased significantly. Behaviors were clustered according to their path: taking into account its relationship with both zonal and provincial level stratum averages. Areas like the Oasis Sur have suffered a major a regressive process that has involved almost all the strata. The Uco Valley has shown a significant dynamism in units of more than 25 ha, while the small holdings have moved back, but with lower rates than the average of these strata. The Oasis Norte has also been subject to a bipolar process where a significant loss of small vineyards with the rise of new big holdings. Oasis Este is the only one that remains with lower regression rates.

La incorporación de un número significativo de inmigrantes a finales del siglo XIX junto a un proceso de reorganización productiva asociado al desarrollo de la industria vitivinícola, implicó cambios en las relaciones sociales y en las condiciones de vida de amplios sectores de la población mendocina. Iniciado el siglo XX, la vitivinicultura se convirtió en la principal actividad productiva de la provincia y la más importante en su rubro a nivel nacional. Los viñateros, productores agroindustriales, industriales bodegueros, contratistas de viñas , etc., fueron constituyéndose en parte de una sociedad cada vez más heterogénea y diversa, producto del desarrollo capitalista que experimentó la región desde el último tercio del siglo XIX y que se insertó en el proceso de incorporación de la economía Argentina al mercado mundial. Este período resulta de suma importancia porque se determinó un sistema productivo en torno a la actividad vitivinícola de la provincia que dio forma al mercado de trabajo regional. En este contexto, la inserción de los trabajadores se dio de una manera muy dispar en el proceso productivo, caracterizado por una alta estacionalidad y una escasa especialización de la mano de obra requerida.The aim of this work is to analyze the changes and continuities during the process of formation of the labor market in the province of Mendoza in the early 1900s.

Otero, Federico; Norte, Federico; Araneo, Diego

2018-01-01

The aim of this work is to obtain an index for predicting the probability of occurrence of zonda event at surface level from sounding data at Mendoza city, Argentine. To accomplish this goal, surface zonda wind events were previously found with an objective classification method (OCM) only considering the surface station values. Once obtained the dates and the onset time of each event, the prior closest sounding for each event was taken to realize a principal component analysis (PCA) that is used to identify the leading patterns of the vertical structure of the atmosphere previously to a zonda wind event. These components were used to construct the index model. For the PCA an entry matrix of temperature ( T) and dew point temperature (Td) anomalies for the standard levels between 850 and 300 hPa was build. The analysis yielded six significant components with a 94 % of the variance explained and the leading patterns of favorable weather conditions for the development of the phenomenon were obtained. A zonda/non-zonda indicator c can be estimated by a logistic multiple regressions depending on the PCA component loadings, determining a zonda probability index \\widehat{c} calculable from T and Td profiles and it depends on the climatological features of the region. The index showed 74.7 % efficiency. The same analysis was performed by adding surface values of T and Td from Mendoza Aero station increasing the index efficiency to 87.8 %. The results revealed four significantly correlated PCs with a major improvement in differentiating zonda cases and a reducing of the uncertainty interval.

The strontium, carbon and oxygen isotopic signal of the past oceans is accurately recorded by authigenic marine minerals such as carbonates, sulfates and phosphates. The variation of these isotope ratios through the geological time is used as a tool in correlating and dating marine sedimentary rocks. Many works have been done concerning to the changes in carbon, oxygen and strontium isotope ratios of different marine successions in the world. These allow the construction of curves of secular variations of the isotope signals with geological time (Jones et al., 1994a, 1994b; Veizer et al., 1999; Jacobsen and Kaufman, 1999). This work presents strontium, carbon and oxygen isotope ratios of Early Jurassic biogenic marine carbonates of Cuenca Neuquina in southwestern Mendoza (au)

Full Text Available Lately, several authors have been analyzing the changes in rural areas triggered by globalization. The concepts of new rurality and pluriactivity have allowed progress along these lines, highlighting the new difficulties facing the most vulnerable sectors. This study explores the transformation of peripheral rural territories in Mendoza (Argentina, particularly those that have been thought of as isolated and traditional. This research develops from a case study, combines quantitative and qualitative methods, and takes the production undertakings happening in those lands as units of analysis. Production and economic situations of the past are compared to those in the present. The tendency toward pluriactivity is here considered as a response to the new conditions, and also as an expression of the process of articulation with the capitalist system.

Full Text Available Due to its geographical location, the community of Motozintla de Mendoza (Motozintla in the State of Chiapas, Mexico, is continuously exposed to the impact of natural hazards. In this work, we assessed the flood risk of Motozintla considering the structural, socioeconomic, organizational, and global (structural, socioeconomic, and organizational vulnerabilities. In addition, we also measured the local risk perception. Spatial maps were generated to determine the most vulnerable and risk areas of this community. Our results indicate that the population has a high level of risk to flooding mainly because (1 the majority of the local houses has high structural vulnerability; (2 a high percentage of the families has a daily income less than the official Mexican minimum wage and lacks of basic public services as well as of proper social security services; (3 most of the community does not know any existing Civil Protection Plan; and (4 the community organization for disaster mitigation and response is practically non-existent. For these reasons, we believe that it is necessary for local authorities to establish in the short-term, preparedness, mitigation and response plans as well as land-use measures to reduce the risk to floods in Motozintla.

Full Text Available La reflexión acerca de la identidad latinoamericana había sido encomendada tradicionalmente a la literatura y las humanidades, para, a partir de los años ’80, desplazarse hacia las ciencias sociales y de la comunicación. La transdisciplinariedad se ha convertido entonces en método irrenunciable, pero la autora propone que, frente a la convivencia acrítica, los estudios culturales deben usar los bordes de conflicto entre disciplinas humanísticas y tecnológicas para oponerse al sistema hegemónico que hace primar a las segundas sobre las primeras, y recuperar la capacidad del arte, la literatura y el pensamiento crítico para reintroducir los desórdenes de lo inclasificable en el mundo de lo clasificado y lo clasificador. Reflections on Latinoamerican identity was traditionally linked to literature and humanities. From the 80’s, it slowly swerved to social sciences and communication. Approaches across disciplines have become mainstream, but this author suggests that, unlike non critical coexistence, cultural studies must accommodate to conceptual conflicts on the edge of disciplines building bridges between humanistic disciplines and technological ones in such a way that the latter are not meant superior in any way and the former are instrumental in turning upside down the straitjacket of the orderly world that technology renders.

Spontaneous fermentations are still conducted by several wineries in different regions of Argentina as a common practice. Native Saccharomyces strains associated with winery equipment, grape and spontaneous fermentations of Malbec musts from "Zona Alta del Río Mendoza" region (Argentina) were investigated during 2001 and 2002 in the same cellar. Low occurrence of Saccharomyces on grapes and their limited participation during fermentation were confirmed. Strain sequential substitution during fermentation was observed. Between 30% and 60% of yeast population at the end of fermentation was coming from yeasts already present in the winery. A stable and resident Saccharomyces micro-flora in the winery was confirmed. It exhibited a dynamic behaviour during season and between years. Commercial strains were found during fermentation in different percentages, but their presence on winery equipment was low. The present work represents a first approach to winery yeast and spontaneous fermentation Saccharomyces population dynamics in an important viticultural region from Argentina that has never been characterized before. The results obtained have an important significance for the local industry, showing for the first time the real situation of the microbial ecology of alcoholic fermentation in an industrial winery from Mendoza, Argentina.

The investigation tries to quarrel if in the period of this constitution life (1854-1895, nevertheless the bigger complexity of the state mechanisms and the politics of strengthening the legal authority on the territory, there were spaces that escaped to this power, or practices resistant to the principles in vogue. The work has put on particular attention to the rural localities, which for the distances or small accessibility, is estimated they were less inclined to the changes and less exposed to the state control.El trabajo analiza la efectiva aplicación de los principios del moderno constitucionalismo en Mendoza luego de formalizado el orden liberal mediante la carta magna provincial de 1854. Trata de averiguar, si en el período de su vigencia (1854-1895, no obstante el proceso de complejización del aparato estatal y la política de afianzamiento de su potestad sobre el territorio, quedaron espacios que escaparon a ese poder, o se dieron prácticas resistentes a los principios en boga. Se ha puesto particular atención a las localidades de la campaña, que por las distancias o la poca accesibilidad, se estima eran poco proclives a los cambios y estaban menos expuestas al control estatal.

2013-06-01

Full Text Available Este trabajo propone trazar un panorama general del desarrollo de la Arquitectura Moderna en Mendoza entre 1930 y 1970, a través de los autores y obras más significativos. La producción arquitectónica lograda en el período, en el presente de valor patrimonial, no cuenta con acciones gubernamentales ni legislación de protección. Esto se debe a dos razones concurrentes: La primera, desde el imaginario social el recorte temporal de lo patrimonial finaliza con la arquitectura de los años ’20 del siglo pasado. La segunda razón, la estética y la vigencia funcional de estas obras impiden poner la distancia crítica que requiere toda mirada histórica, aún más desde lo cultural. Vamos a revisar algunos autores a partir de sus trayectorias y su producción arquitectónica, con el objetivo de descubrir las singularidades de la producción local, haciendo aportes para la valoración de estos bienes y por ende para su patrimonialización.

Full Text Available Bien es conocida la voluntad permanente en en un director como Pedro Almodóvar de utilizar lo más posible las posibilidades específicas del lenguaje cinematográfico y de trabajar todos los segmentos del discurso del cine. Por eso, desde sus primeras películas, Almodóvar ha cuidado mucho los dos umbrales del relato filmico que son los títulos de créditos de principio y de final. Uno de los ejemplos más significativos al particular es el de Mujeres al borde de un ataque de nervios que nos proponemos estudiar detenidamente al mismo tiempo que nos servirá como representación del mensaje esencial de la película._____________________ABSTRACT:We know that Almodovar is a director who thrives at using all the specific means put at his disposal by the cinematic language.

Facial / microfacial studies and geochemical isotopic analyses on marine jurassic carbonates of the Calabozo Formation (Dessanti, 1973) were carried out to reconstruct the palaeoenvironment and postdepositional history of the unit. This study is part of a project which purpose is the sedimentological and geochemical characterization of the Jurassic carbonate sequences of Cuenca Neuquina, in the southwestern Mendoza, Argentina. A detailed description about this basin can be found in Legarreta and Uliana (1999) and Riccardi et al. (2000). During the Late Bathonian and Early Callovian, the basin showed a reduction of the sedimentation area and a marked marginal facies progradation. West of Malargue, in areas with low detritic contribution, limestones of the Calabozo Formation were deposited. At the end of the Early Callovian, the basin was isolated, prevailing hypersaline conditions which caused the accumulation of the evaporites of the Tabanos Formation (Stipanicic, 1966) (au)

Full Text Available En la Reserva Forestal de Cogua (Colombia, estudiamos mediante transectos la vegetación leñosa en dos parches de bosque altoandino para tres tipos de borde: chusque, paramizado y antiguo (este último denominado así por presentar un estado sucesional más avanzado. Seleccionamos como especies típicas de borde las que tenían mayor abundancia en esta zona, presentes en ambos parches del borde y capaces de colonizar la matriz adyacente. Se obtuvo un conjunto de nueve especies a las cuales se les evaluaron 20 atributos vitales, generando seis grupos mediante un análisis de agrupamiento (cluster: 1 Weinmannia balbisiana-W. tomentosa, 2 Gaiadendron punctatum-Hedyosmum bonplandianum, 3 Miconia ligustrina-M. squamulosa, 4 Macleania rupestris, 5 Pentacalia pulchella y 6 Tibouchina grossa. La amplia variación y plasticidad de las especies estudiadas en cuanto a los atributos analizados, conduce a pensar que los conjuntos obtenidos no obedecen a grupos funcionales claramente diferenciados, sino más bien a estrategias diferentes y que estas especies podrían hacer parte de un solo grupo funcional de gran plasticidad. T. grossa es la especie de borde más exitosa en la reserva, dados sus altos valores de abundancia, tolerancia fisiológica, reproducción vegetativa, producción de hojarasca y producción de semillas pequeñas, numerosas, formadoras de un banco de semillas persistente que evidencian su alta fecundidad.Vital traits of woody species in High Andean forest edges of the Cogua Forest Reserve (Colombia.

This contribution shows the main characteristics of the talc mineralization related to the Río de Las Tunas ultramafic bodies in the Salamanca Mining District, Frontal Cordillera of Mendoza province. According to the parageneses defined on the studied samples, three generations of talc were established: 1º crystallized in metaperidotites and related to the prograde stage of the regional metamorphism; 2º crystallized inreaction zones (mostly in the talc zone developed at the boundary between metaperidotites and their country-rocks.These reaction zones evidence a metasomatic process due to geochemical gradient between the ultramafic body and their country-rocks. This process was developed during the retrogression of the regional metamorphic cycle. 3º Talc present in shear-zones that cut across the ultramafic bodies. The extreme serpentinization of the ultramaficbodies is concentrated in shear-zones where the serpentine is subsequently replaced by talc ± carbonates related with a hydrothermal stage. Aqueous fluids relatively enriched in CO2 flowed through these shear-zones causing the cease of serpentine formation favoring the talc and/or carbonates. Mined talc deposits are those in shear zones and reaction zones. They are mostly industrial-, asbestine- or talcschist-type. The talc related to the hydrothermal stage can locally reach first and extra qualities.

Full Text Available O presente trabalho teve por objetivo determinar a influência da desfolha e da época da poda seca sobre o albedo e sobre a radiação solar disponível ao nível dos cachos e determinar o efeito da radiação solar sobre o acúmulo de sólidos solúveis da videira. Foram realizadas duas épocas de poda seca e a desfolha em parte do vinhedo da cultivar Bordô conduzida no sistema pérgula. A radiação solar foi medida utilizando-se tubos solarímetros instalados em cada tratamento, sendo o teor de sólidos solúveis determinado no momento da colheita, com um refratômetro de campo. A realização da poda seca exerceu influência sobre o albedo, sendo que o maior albedo da videira Bordô é observado quando a poda seca ocorreu na época normal (meados de setembro e sem desfolha. Para o período compreendido entre a poda e a desfolha, o albedo variou entre 0,28 e 0,30. Os resultados demonstram que o adiamento da poda seca representa redução na quantidade de radiação solar disponível ao nível dos cachos, ao mesmo tempo em que a realização da desfolha propicia aumento na radiação que incide ao nível dos cachos. O acúmulo de sólidos solúveis está relacionado com a radiação solar disponível ao nível dos cachos.

The metamorphic basement of the Cordillera Frontal of Mendoza: New geochronologic and isotopic data

International Nuclear Information System (INIS)

Basei, Miguel; Ramos, Victor A.; Vujovich, Graciela I.; Poma, Stella

1998-01-01

The metamorphic rocks of the Cordillera Frontal exposed in the Cordon del Portillo, Mendoza were examined by Rb/Sr geochronology and Nd/Sm isotopic analysis. The Rb/Sr data defined a Devonian age for the last metamorphic episode, similar to the previous K/Ar and Ar/Ar ages obtained in this region and western Precordillera. The isotopic analysis identified three sets of model ages: 1.- The oldest corresponds to a set of meta sedimentary rocks with a model age of 1,400 to 1,700 Ma; 2.- A monzogranodiorite with a model age of 1,000 Ma; and 3.- Metabasites with model ages between 577 and 330 Ma. These rocks are interpreted as 1.- A typical Grenvillian derived basement; 2.- Late Paleozoic granitoids derived from a different Proterozoic basement; and 3.- Some Eopaleozoic metabasites tectonically inter fingered with the Grenvillian basement. These new data are coherent with the existence of a Laurentia derived terrane, Chilenia, that was separated by oceanic rocks from the basement of Pre cordillera during Eopaleozoic times. This last basement known as the Cuyania terrane, was also derived from Laurentia. (author)

Se determinó el número de generaciones anuales y se estudiaron las fluctuaciones poblacionales asociadas a la integral térmica para la especie en esta región. D. perniciosus presenta dos generaciones superpuestas al ciclo del cultivo, mientras que las ninfas (N1 y N2 de la tercera generación se desarrollan solamente hasta el final de la temporada estival y pasan al estado de quiescencia, en el que permanecen durante el invierno. El desarrollo de D. perniciosus en esta zona coincide con el de esta especie en la zona frutícola del centro de Chile en cuanto al número de generaciones y al periodo de quiescencia invernal. La población quiescente en Chile está integrada predominantemente por ninfas del primer estadio (N1, mientras que en San Carlos, Mendoza, la población quiescente está integrada principalmente por ninfas del segundo estadio (N2. La similitudes entre ambas poblaciones se deben, probablemente, a las coincidencias en latitud, clima y especie hospedera. El impacto económico de D. perniciosus en la zona de estudio tiene mayor relevancia durante los meses de diciembre y enero, cuando se observa una alta incidencia de daños en los frutos y las hojas; este es el momento decisivo para implementar medidas de control fitosanitario.

Full Text Available This paper explores the muleteer as an economic actor in terrestrial transportation in South Cone, specially in the route across the Andes in order to connect Atlantic and Pacific markets. Since Mendoza’s customs records, this study has processed 120.000 freight-carrying mules to know the origin and destiny places, main routes, volume and kind of charge. The muleteer promoted an intensive activity in terms of transportation, trade and wine industry. As a result, he leaded the rise of a regional proto-bourgeoisie.

El artículo examina al arriero como actor económico en el transporte terrestre del Cono Sur, sobre todo en la ruta a través de la Cordillera de los Andes, para enlazar los mercados del Atlántico y el Pacífico. A partir de los manuales de Cargo y Data de la Aduana de Mendoza, se han procesado 120.000 mulas de carga para determinar los lugares de origen y destino, principales rutas, volumen y tipo de carga transportada. El arriero impulsó una intensa actividad en el transporte, el comercio y en la industria vitivinícola; como resultado, este actor promovió el surgimiento de una protoburguesía regional.

Full Text Available El objetivo de la presente investigación fue entender cuáles son las dinámicas territoriales que se producen en las periferias rural-urbanas de la ciudad de Medellín y cuáles son los factores que las producen. Se encontró que la amplia difusión de los medios de transporte, las expectativas de un precio del suelo y de la vivienda más bajo y/o de un mejor entorno ambiental, presionan las zonas rurales aledañas a la ciudad de Medellín; este fenómeno se conoce con los nombres de suburbanización, periurbanización y contraurbanización. En estas áreas rural- urbanas, se producen trozos de ciudad a través de intereses y proyectos mayoritariamente privados, debido a que el desarrollo inmobiliario ha pasado a convertirse en uno de los pilares del crecimiento de la economía, así como también a que las áreas rurales del Departamento expulsan a sus pobladores hacia la ciudad, los cuales se instalan principalmente en los bordes de la ciudad. Esta ocupación de las periferias rural- urbanas está generando destrucción y alteración de los ecosistemas y los paisajes tradicionales, desarticulación de las actividades rurales y está desbordando absolutamente los marcos de planeamiento preexistente.

Full Text Available El deshielo de la nieve acumulada durante el invierno en la cuenca alta del río Mendoza constituye el principal suministro de agua para la agricultura, la industria y el consumo humano en los sectores bajos adyacentes. Sin embargo, a pesar de su gran importancia, hay muy pocos estudios que permitan conocer y entender la variabilidad espacial y temporal de la nieve en este sector de los Andes Centrales de Argentina. En este trabajo presentamos una técnica para cuantificar la evolución diaria de la cobertura nival en esta cuenca basada en la integración de imágenes de los sensores MODIS Aqua y Terra para el período 2000 y 2014. La técnica muestra disminución en la pérdida de información por presencia de nubosidad y fue realizada utilizando herramientas y funciones de los lenguajes de programación Libres R y BASH. Las series de cobertura de nieve obtenidas muestran importantes variaciones estacionales con aumentos de la cobertura nival en invierno (58% de cobertura máxima en promedio y reducciones significativas en verano. Asimismo, se observa una importante variabilidad interanual con claras diferencias entre años secos (ej. 2010, con 12% de cobertura promedio y nevadores (ej. 2005, 32% de cobertura anual promedio. Los mapas de cobertura nival muestran además que los sectores con mayor persistencia de nieve coinciden con la ubicación de glaciares, en los sectores más elevados, protegidos y de menor insolación de la cuenca. Los resultados brindan información novedosa y relevante para conocer y entender de forma más completa la distribución y variabilidad de la cobertura nival en este sector de la cordillera. Los mismos pueden servir de base para múltiples aplicaciones incluyendo el modelado hidrológico de la cuenca del río Mendoza contribuyendo al manejo racional de sus recursos hídricos.

A tectonically affected Middle Ordovician succession crops out at the Los Guanacos quarry in the sierra de Las Higueras, in the Precordillera of Mendoza, western Argentina. This is represented by the San Juan Formation which is transitionally covered by a mixed carbonate-shaly unit of dark colours, 1.5 metres thick (transfacies) which can be interpreted as the base of the Los Azules Formation. A 5-cm thick intra-bioclastic pack/grainstone bed interbedded in the lower part of this unit has been interpreted as a tempestite. It is characterized both by a millimetre-thick erosional boundary, just above the dark mudstone layer and strong mechanical distribution of bioclasts and intraclasts, suggesting sedimentary structures associated with a storm event of high energy possibly occurring in the middle part of the platform. Towards the bottom, a hummocky structure thin interval, under the dark mudstone, is interpreted as the record of another tempestite event. The mudstone represents the post-storm event reflecting the low energy of the marine water environment. The lenticular layer contains predominantly lingulid shells, trilobites and graptolites, all highly fragmented, which suggests they have been reworked and subsequently mixed and quickly redeposited during a storm event that caused the mortality of these faunas. The trilobites Mendolaspis salagastensis and indeterminate species of Matagnostidae, Illaenidae, Leiostegiidae, Encrinuridae, Telephinidae and Trinucleidae have been recorded for the first time at this locality. The conodont fauna allows the identification of the Yangtzeplacognathus crassus Zone, which indicates the lower Darriwilian (Middle Ordovician). Graptolites assignable to evisograptus cf. Levisograptus austrodentatus and Levisograptus sp. are described for the first time in the studied area and biostratigraphic implications validate the early Darriwilian age for the bearing levels. Finally, based on the studied records, correlation with different

A review of the main characteristics of the alpine tectonic phases is given. From these data, differences between the Gredos zone, dominated by N-S and E-W faults, and the Guadarrama zone, in which N 70° E reverse faults with N 140° E and N 10° E strike-slip faults are present, can be observed. The pattern of drainage of this area shows three main orientations, coincident with the alpine faults activated during the Guadarrama tectonic phase, which reveals the relationship between the present drainage pattern and the Alpine orogeny.En este trabajo se describen las principales estructuras alpinas del borde norte del Sistema Central y su enlace con la cuenca del Duero, así como las características de las principales fases tectónicas alpinas que han dado lugar a la actual estructura.

El análisis de las direcciones de los ríos en este área permite definir tres zonas en función de su orientación, que coinciden con las definidas para las fallas alpinas, lo que refleja la relación entre la red de drenaje y la fase alpina Guadarrama principalmente.

Genesis of sandstone-type uranium deposits in the Sierra Pintada district, Mendoza, Argentina: a Moessbauer study

1982-01-01

The genesis of sandstone-type uranium deposits in the Cochico Group (Permo-Triassic) of the Sierra Pintada district, San Rafael, Mendoza, has been studied. This is the most important uranium district in Argentina. Uranium sources, uranium transport and precipitation are discussed. Uraninite and brannerite, the main uranium minerals, occur within the matrix of sandstone. Several phenomena can be deduced regarding the depositional environment. Where oxygen was available, precipitation of hydrated ferric oxides occurred; γFe 2 O 3 .nH 2 O varieties (identified by Moessbauer spectroscopy) precipitated in the upper levels of the aquifer, where CO 2 partial pressure was lower, giving reddish or reddish-brown beds. The CO 2 partial pressure also determines the distribution of biogenic agents such as bacteria. Bacteria thus find a more favourable environment for their development and action in upper levels of an aquifer. In the corresponding horizons local reduction occurred where UO 2 precipitated; therefore the highest uranium concentrations correspond to sandstone levels with reddish or reddish-brown pigment. These pigments have been identified by Moessbauer spectroscopy. (Auth.)

With the objective of analyzing aspects related to the perception of working conditions and their impact on health in the teachers and professors who work for the Universidad Nacional de Cuyo (UNCuyo) in Mendoza, Argentina, this work analyzes the results of the Primer Censo de Condiciones y Salud Laboral [First Census on Health and Working Conditions]. The census was conducted in late 2013 in two academic units (one at the high school level and the other at the university level), including 193 educators. The exploration set out to characterize the teaching staff and the conditions affecting their health, primarily with respect to psycho-social health. In order to do, so a self-administered questionnaire was applied, the dimensions of which were discussed in sensitivity workshops with educators who helped to formulate the data collection instrument. Among the primary results emerge the physical and emotional burnout of these highly skilled workers, owing to the combined effect of their committed response to the demands of their work and the deterioration (both material and symbolic) of the conditions in which they carry out that work.

Full Text Available Medium strength AW7XXX aluminium alloys are widely used as welded structures and in transportation. The applications of these alloys are limited by the behavior of the welded joints. There is not an agreement on the joint geometry that must be used on the 5 mm aluminium welds. The microhardness evolution is one of the most important strength indicator, For this reason, the aim of this work is to study the welded joint geometry influence on microhardness profile and on microstructure of a welded aluminium alloy AW7020 MIG, filled with AW5356.

Las aleaciones de aluminio de la serie AW7XXX de medias prestaciones se están empleando ampliamente en el sector del transporte, así como en la construcción de estructuras soldadas. La posibilidad de que estas aleaciones se empleen con mayor profusión está condicionada a un mayor conocimiento del comportamiento de la unión soldada. La evolución de la microdureza como un indicador de resistencia es ampliamente utilizado, pero no hay acuerdo sobre el efecto de la preparación de bordes previo a la soldadura y es por ello que el objetivo de este trabajo sea estudiar la influencia de la preparación de bordes sobre el perfil de microdureza y microestructura de la unión soldada de una aleación de aluminio AW7020, soldada mediante el proceso MIG, empleando como metal de aporte AW5356.

En este trabajo se analizan, de manera comparativa, cuatro ensayos con diferentes sistemas de aplicación de enmiendas orgánicas (prácticas agrícolas, tipo de enmienda, dosis, frecuencia y forma de aplicación y combinación con fertilizantes químicos en oasis de regadío de Mendoza (Argentina, con la finalidad de establecer las prácticas de manejo más adecuadas para restaurar las diferentes fracciones de MO del suelo (ácidos húmicos y fúlvicos y sustancias no húmicas. El contenido de MO aumentó en el 40% de los casos analizados (n=92 y no sufrió modificaciones en el resto, mientras que los ácidos fúlvicos también aumentaron en el 40% de los casos, pero disminuyeron en el 30%. Contrariamente, los ácidos húmicos sufrieron más disminuciones que aumentos (39% vs. 26% de los casos. Estas diferencias se explican por las prácticas de manejo agrícola y las técnicas de aplicación de las enmiendas, concluyendo que: a todas las prácticas de aplicación de enmiendas aumentan en el corto plazo la MO; b la fracción humificada aumenta en el corto plazo, con la aplicación superficial sin laboreo; y c el agua de riego con alto contenido de desechos orgánicos disminuye el efecto positivo de las enmiendas sobre la MO. Por tales motivos, las prácticas de manejo recomendadas para lograr la restauración de la MO del suelo en los oasis de regadío de Mendoza son: aumentar la dosis y la frecuencia en la aplicación de enmiendas, y reducir el laboreo y el uso de aguas de reuso.

Discovery of the Sierra Pintada uranium district, Mendoza Province, Argentina

International Nuclear Information System (INIS)

Rodrigo, F.; Belluco, A.E.

1981-01-01

Since 1956, uranium-bearing minerals have been known to exist in Sierra Pintada, Mendoza Province, Argentina. Based on paragenetic considerations, a first radiometric prospection was carried out, leading to the discovery of two groups of anomalies (Puesto Agua del Toro and Cuesta de los Terneros), such as vein-type deposits, with uraninite and 'yellow minerals' and one sandstone-type deposit (Puesto La Josefa), related to sediments with carbon trash. Some recent geological research and surveys in the area, and a reduced drilling programme carried out on selected anomalies, led to reinterpretation of the potential of the area. Furthermore, and as a result of an airborne radiometric prospection performed in mid-1968, numerous anomalies have been discovered. The main constellation of anomalies, along the flanks of the El Tigre Brachyanticline, occurs in sandstones of Permian age. Explored by 80 000 m of drilling, they have shown the existence of several peneconcordant lens-shaped ore bodies of economic size, with uranophane on the surface and prevailing uraninite and some brannerite, coffinite and davidite below the water table. Reserves exceed 20 000 tonnes of U 3 O 8 . A new regional programme with a 4-km drill-grid initiated in 1978 led to the discovery of new ore bodies which are at present being evaluated. The alternatives and discontinuities during the development of the district, the prospecting and exploration techniques employed, and the results achieved in the different stages of the operation are discussed in detail. This case history attempts to illustrate the developing philosophy which was successfully applied in Sierra Pintada, with emphasis on the following points: (a) the need for adequate geological knowledge of the area; (b) the advantage of a massive survey (in this case, air survey); (c) the necessity for exploration (drilling) in order to define the anomalies and make their evaluation possible; and (d) the convenience of extending exploration

Satellite image such as Landsat 5 TM scene provides excellent representation of Earth and synoptic view of large geographic areas in different band combination. Landsat TM images allow automatic and semi-automatic classification of land cover, nevertheless the software frequently may some difficulties in distinguishing between similar radiometric surfaces. In this case, the use of Digital Elevation Model (DEM) can be an important tool to identify different surface covers. In this study, several False Color Composite (FCC) of Landsat 5 TM Image, DEM and the respective draped image of them, were used to delineate lithological boundaries and tectonic features of regional significance of the Paven Volcanic Field (PVF). PFV is a Quaternary fissural structure belonging to the black-arc extensional areas of the Andes in the Mendoza Province (Argentina) characterized by many composite basaltic lava flow fields. The necessity to identify different lava flows with the same composition, and then with same spectral features, allows to highlight the improvement of synergic use of TM images and shaded DEM in the visual interpretation. Information obtained from Satellite data and DEM have been compared with previous geological maps and transferred into a topographical base map. Based on these data a new lithological map at 1:100.000 scale has been presented [it

The Plio-Pleistocene Llancanelo volcanic field is located in the south-eastern region of the province of Mendoza, Argentina. This wide back-arc lava plateau, with hundreds of monogenetic pyroclastic cones, covers a large area behind the active Andean volcanic arc. Here we focus on the northern Llancanelo volcanic field, particularly in Las Bombas volcano. Las Bombas volcano is an eroded, but still recognizable, scoria cone located in a circular depression surrounded by a basaltic lava flow, suggesting that Las Bombas volcano was there when the lava flow field formed and, therefore, the lava flow engulfed it completely. While this explanation seems reasonable, the common presence of similar landforms in this part of the field justifies the need to establish correctly the stratigraphic relationship between lava flow fields and these circular depressions. The main purpose of this research is to investigate Las Bombas volcano 3D subsurface architecture by means of geophysical methods. We carried out a paleomagnetic study and detailed topographic, magnetic and gravimetric land surveys. Magnetic anomalies of normal and reverse polarity and paleomagnetic results point to the occurrence of two different volcanic episodes. A circular low Bouguer anomaly was detected beneath Las Bombas scoria cone indicating the existence of a mass deficit. A 3D forward gravity model was constructed, which suggests that the mass deficit would be related to the presence of fracture zones below Las Bombas volcano cone, due to sudden degassing of younger magma beneath it, or to a single phreatomagmatic explosion. Our results provide new and detailed information about Las Bombas volcano subsurface architecture.

Permo-triassic volcanism in the San Rafael Block (Mendoza province) and its uraniferous potential

International Nuclear Information System (INIS)

Kleiman, L.E.

1993-01-01

This paper describes the Permo-triassic volcanism in the San Rafael Block, Mendoza, Argentina, which forms part of the Choiyoi province and it represents by large volumes of intermediate to silicic ignimbrites with minor sub volcanic bodies of rhyolites, andesites and basandesites. Three different suites can be distinguished: the first one (Lower Section) of Early Permian age, is composed of dacites and rhyolites (SiO 2 up to 71 %) with minor andesites, the second one (Upper Section) of Late Permian-Early Triassic age is made up of rhyolites (SiO 2 up to 77 %) with some basandesites and andesites, and the third one, of Triassic age is composed of rhyolites (SiO 2 > 75 %) and basandecites. These suites are easily distinguished by means of trace element data and are believed to represent the transition between a subduction-related magmatic arc and an extensional tectonic regime. This tectonic setting is similar to the prevalent during the Cenozoic in the Sierra Occidental of Mexico and is favourable for the development of long-lived hydrothermal systems which lead to economic U concentrations (i.e. Sierra de Pena Blanca). In the San Rafael Block, the Dr. Baulies-Los Reyunos U deposit, which is hosted in volcanic sediments, is associated to the first suite (Lower Section). Although minor U concentrations are known, up to date, to be related to the second and third suites, these rocks are fertile and seen to be potential source for the formation of uranium deposits within a volcanic caldera environment.

Solar radiation in forested urban environments with dry climate. Case: Metropolitan Area of Mendoza, Argentina

2014-12-01

Full Text Available The aim of this work is to advance the understanding of the solar potential of urban residential environments which, by their morphology, and the impact of urban trees, present values of irradiance very different from full solar collection. Morphological variables of urban settings and urban trees, a very distinctive feature of the Mendoza Metropolitan Area (MMA, have a fundamental impact on the feasibility of implementing strategies for solar energy utilization in urban environments. The results achieved will contribute to modify and gradually update urban and building legislation to implement higher levels of energy efficiency and minimum environmental impacts.This work proposes to study the potential of solar collection in urban environments, analyzing eleven urban configurations selected according to their building and urban morphological characteristics.Methodologically, we have monitored the global solar irradiance on vertical plane on northern facades, completely sunny and partly sunny, affected by solid masking and arboreal masking. Results obtained so far indicate that solar masking is critical for vertical surfaces, with a reduction of the available solar energy between 2% and 66% in the winter season. However, these drawbacks caused by urban trees are compensated by benefits in the warm season: controlling the intensity of the urban heat island, absorption of pollutants, cooling and humidifying the air through evapotranspiration, reducing thermal loads of buildings, occupancy of public open spaces, and an invaluable contribution to the urban aesthetic.

Equilibrium is directly expressed by means of partial differential equations, in terms of the membrane shape and stress tensor. Starting from these equations, two dual approaches can be defi ned, namely direct problem and dual problem. Both problems are analyzed, studying their possible solutions in order to obtain practical results. In particular, the main analytical aspects of the direct problem are discussed, a numerical resolution procedure is proposed and, fi nally, analytical and numerical solution examples are presented.Este trabajo aborda el análisis del equilibrio de una membrana con borde rígido. La idea de utilizar las membranas en aplicaciones tales como las pasarelas, una nueva tecnología que se está desarrollando en España, requiere un análisis estructural muy ajustado. Debido a los esfuerzos de tracción, la membrana se identifi ca a una superficie con curvatura de Gauss negativa. De esta forma, el equilibrio se expresa directamente por medio de ecuaciones diferenciales en derivadas parciales, en términos de la forma de la membrana y del tensor de esfuerzos. A partir de dichas ecuaciones, se pueden considerar dos enfoques complementarios, aquí llamados problema directo y problema dual. Se analizan ambos problemas, estudiando sus posibles soluciones con el objetivo de obtener resultados prácticos. En particular, se profundizan los principales aspectos analíticos del problema directo, se propone un método numérico para la resolución y, fi nalmente, se presentan ejemplos de solución analítica y numérica.

The diffraction of a non uniform plane electromagnetic wave by the edge of a electrically perfectly conducting half plane in a bi-anisotropic media is rigorously analyzed. The high-frequency asymptotic expansion reveals the existence of a coupling effect between a transverse magnetic (or transverse electric) incident plane wave and the transverse electric (or transverse magnetic) slope-diffracted field. A numerical verification using the Mathematic software is presented. [Spanish] Se analiza rigurosamente la difraccion, de una onda plana electromagnetica no-uniforme, en el borde (edge) de un semiplano perfectamente conductor inmerso en un medio quiral (bi-anisotropo). La expansion asintotica de la solucion exacta en alta frecuencia, evidencia la existencia de un efecto de acoplamiento, entre la onda plana transversal magnetica incidente (o transversal electrica) y el campo transversal electrico producido por la difraccion-pendiente (o transversal magnetico). Los campos difractados se evaluan numericamente utilizando el software Matematica.

The origin of the International Center for Earth Sciences (ICES) dates back to 2002 when the Acoustic Emission Station on Volcano Peteroa was installed. Up to now, it represents the first of its kind in the entire Andean Cordillera. This scientific activity is jointly coordinated by scientists from Italy and Argentina. At the First Conference on Acoustic Emission held on 2004, a letter of intent for the establishment of ICES was signed. Presently, ICES is composed by 4 departments: Environment and Climate; Anthropology; Environmental and Territorial Environmental Risk; Resources and Exploration Geophysics. One of the primary objectives of ICES is to promoting applied research and development in the broad field of Earth Sciences. The experimental work consists of main 4 steps listed below: The 'Helianthus annus' (sunflower) has proven its ability to raise Uranium (U) in hydroponic systems and was widely used in the model U rizophyiltration extraction of groundwater in Ashtabula, Ohio, USA. Hydroponic trial design consists of 6 treatments and 4 repetitions plants witnesses without minimum level of U, U witnesses plants without and 4 with various levels of U (Stage 1). The Glomus intraradices is a mycorrhizal fungus used in strategies of U phyto-stabilization. Test consists in the cultivation of sunflower with roots inoculated with Glomus intraradices to determine their uptake and translocation of U (Stage 2). The inoculation of 'Glomus intraradices' in 'Helianthus annus' produces an effective symbiosis with the type of strain and its genetic diversity, some genotypes are highly suitable for this. There have been experiences of this kind in the basic research in several countries. In this work, we use the system in 'Helianthus-Glomus' phyto-stabilization or rizophyiltration soil as a strategy for bioremediation of U at the Malargue area, Province of Mendoza (Stage 3). It will launch a pilot test of the transfer plan, which involves creating a garden for the growth of

Full Text Available RESUMEN: Alfonso Hojeda fue un notable canonista sevillano que en 1576 publicó en Venecia un libro acerca de los beneficios eclesiásticos. La obra se divide en dos partes: la primera está dedicada a argumentar en contra de la pluralidad de beneficios en una misma persona, de acuerdo con los decretos tridentinos de reforma, mientras la segunda trata en cambio de la compatibilidad de beneficios mediante dispensa papal. Los propios términos en que se manifiestan las dos partes ya están indicando las contradicciones en que ha de moverse el autor, difíciles de salvar. La doctrina de la causa es, además de la distinción entre órdenes normativos, la principal herramienta conciliatoria para Hojeda. El papa está desligado del derecho positivo o humano, pues de otro modo no podría dispensar, o privilegiar, mas sólo puede hacerlo con justa causa.ABSTRACT: Alfonso Hojeda de Mendoza was an outstanding canonist that in 1576 published a book in Venice on the eclesiástica benefits. The book is divided into two parts: the first one is devoted to argue against the plurality of benefits in the same person, according to Trento's decrees, while the second one deals, however, with the compatibility of benefits by the Pope's dispense. The own terms in which both parts are expressed reveal the contradictions, in which the author must move, always difficult to avoid. The doctrine of the cause, as well as the distinction among normative orders, is the main conciliatory tool for Hojeda. The Pope is unlinked to human or positive right, otherwise he could not dispense or privilege, however he can only do it for a just cause.

Full Text Available En el presente artículo analizamos cómo funcionarios de la Municipalidad de Lavalle representan e interpelan a las comunidades indígenas huarpe situadas en el área no irrigada del noreste de Mendoza, área situada en el departamento de Lavalle. Éste se encuentra dividido socioterritorialmente en dos espacios. Uno irrigado, caracterizado como área de progreso, de producción agrícola y de herencia europea y el otro no irrigado, representado como área de atraso, de producción ganadera y de herencia precolonial. A partir de un análisis etnográfico, analizamos cómo el municipio gestiona local y cotidianamente la diversidad étnica, cultural, económica y política. Concluimos que las formas con que los funcionarios interpelan a las comunidades indígenas y a sus integrantes son en base a un doble movimiento, uno de reconocimiento explícito y el otro de individualización, invisibilización y deslegitimación hacia las mismas. Al invisibilizar a las comunidades como sujetos colectivos, funcionarios municipales intentan dar una identidad común que incorpore a los espacios irrigados y no irrigados y a sus poblaciones como pertenecientes a un mismo territorio, el departamental, a la vez que mantenga la jerarquización entre ambos. Al realizar este movimiento, el municipio se erige como el unificador y contenedor de ambos espacios y de los distintos grupos socio-étnicos que los integran.

Asimismo se evaluó la evolución de los records de las pruebas de 100 metros en los cuatro estilos, los 400, 800 y 1500 metros libres ambos sexos en pileta de 25 y 50 metros. Se consideró la cantidad de clubes participantes, los nadadores con licencia nacional en los distintos años y las nominaciones para Seleccionados Nacionales en las distintas décadas. No se obtuvo diferencias estadísticamente significativas entre la evolución de los records realizados en pileta de 25 con la de 50 metros. Se comprobó que disminuyó tanto la cantidad de clubes participantes en los torneos desde 1950 hasta el año 2000 como la de nadadores federados. El estudio nos revela que el nivel competitivo de los nadadores se ha elevado por el aumento en las nominaciones a Seleccionados Nacionales. Como conclusión obtuvimos que posiblemente estos valores obtenidos se deban a la evolución en las técnicas de nado y en los métodos de entrenamiento, interrogante que puede servir para próximos estudios y que, en este caso, la cantidad de deportistas no es directamente proporcional a los logros deportivos.------------------------------------------------------------------------------The investigation that we carried out sustains in an exploratory and descriptive study.

This study was conducted during two consecutive vintages to assess its influence on the general composition, sensory attributes and preference of Vitis vinifera L. cv Malbec wines. Batches of 120 kg of grapes harvested from vines with different degrees of (visual symptoms of the disease were separately vinified. Grapes were grouped in three treatments: T1, grapes from vines with no symptoms; T2, grapes from vines with 10%–50% symptoms; and T3, grapes from vines with 50%–100% symptoms. Basic analyses of the grapes prior to crushing, and basic wine analysis were undertaken, together with spectrophotometric analyses of the wines after three months of bottle aging. The kinetics of alcoholic fermentation (AF was followed daily and additionally the wines were assessed by a sensory panel. T3 grapes were characterized by comparatively lower initial sugar contents and higher titratable acidity. The AF kinetics were unaffected in the wines arising from the diseased grapes. There was no clear-cut effect of the disease on the wines’ pH, volatile acidity, and total acidity; however, the later spectrophotometric analyses showed that the total phenolic index was the highest in T2 wines for both vintages. In 2005, the color index (CI was higher in T3 and showed the lowest value in 2006. The sensory properties of the wines were different in the two vintages. In 2005, T2 and T3 wines were perceived as having higher color intensity, violet hue and spicy notes, T2 being the most preferred wine. In 2006, T1 and T2 showed a much better sensory

Full Text Available This study described a group of strains obtained from a slaughter house in Mendoza, in terms of their pathogenic factors, serotype, antibiotype and molecular profile. Ninety one rectal swabs and one hundred eight plating samples taken from carcasses of healthy cattle intended for meat consumption were analyzed. Both the swab and the plate samples were processed to analyze the samples for the presence of virulence genes by PCR: stx1, stx2, eae and astA. The Stx positive strains were confirmed by citotoxicity assay in Vero cells. The isolates were subsequently investigated for their O:H serotype, antimicrobial susceptibility and molecular profile by Random Amplification of Polymorphic DNA (RAPD. Twelve E.coli strains were identified by their pathogenicity. Nine were from fecal origin and three from carcasses. Three strains carried the stx1 gene, three the stx2 gene, two carried eae and four the astA gene. The detected serotypes were: O172:H-; O150:H8; O91:H21; O178:H19 and O2:H5. The strains showed a similarity around 70% by RAPD. Some of the E.coli strains belonged to serogroups known for certain life-threatening diseases in humans. Their presence in carcasses indicates the high probability of bacterial spread during slaughter and processing.

En este trabajo pretendemos relevar a propósito de la celebración del sesquicentenario de Mayo la producción historiográfica mendocina que circuló en espacios de divulgación, constituyéndose en una fuerte tradición que perduró en los espacios académicos locales. Más allá de explicar la incidencia que tuvieron en la refracción de otras corrientes de pensamiento, las tesis interpretativas que ven a Mayo como un momento de reafirmación de la hispanidad y que niegan su sentido emancipatorio, así como los recorridos biográficos de sus autores, revelan redes de sociabilidad intelectual que bajo la nominación de nacionalismo encubrían no pocas especificidades, al mismo tiempo que revelaban las vinculaciones existentes con la escuela historiográfica sevillana, por entonces usina intelectual del franquismo y nutriente del pensamiento nacionalista conservador y autoritario de los años sesenta.Research on the nationalism present in post- Peronism in Mendoza has allowed us to retrieve a number of intellectual itineraries that exemplify the complexity of a period in which the circulation and traffi c of ideas show not only strong identity mutation processes, but also the crystallization of undoubtedly anachronistic positions.

2016-11-01

The aim of the present study was to analyze the nutritional status and body composition of children from San Rafael, Mendoza, avoiding urban and rural categorization by generating subpopulations as a function of their socio-environmental characteristics. A cross-sectional study was performed in 3,596 schoolchildren from 4.0 to 13.9 years of age. Body weight, height, upper arm circumference, and triceps skinfold were measured. Body mass index, total muscle, and fat areas of the arm were calculated. To estimate nutritional status and body composition, the NHANES III reference was used. The socio-environmental variables were surveyed using a structured questionnaire. These variables were processed by categorical principal-component analysis (catPCA). The catPCA allowed the differentiation of four groups, three with urban characteristics (high urban, medium urban, impoverished urban), and a rural group. Stunting occurred at a higher rate in the impoverished urban group, and the occurrence of underweight children was higher in the rural group. The prevalence of excess weight varied in the range of 20-26%. The latter value corresponded to children of the high urban group, who also did not show reduced muscle mass. Children from San Rafael presented differences in nutritional condition and body composition associated with pronounced socio-environmental heterogeneity. Thus, we could observe a gradient from the "high urban" group, with better social, economic, and sanitation conditions and at the same time a more obesogenic environment to the "impoverished urban" and "rural" groups, whose vulnerability reflected a higher prevalence of child undernutrition and the association with excess weight and reduced muscle mass.

Se muestrearon un total de 1.471 algarrobos en las cuatro unidades boscosas más representativas. La densidad total de algarrobos fue la siguiente: bosque semicerrado de P. flexuosa con Atriplex lampa y Lycium tenuispinosum en valles intermédanos (Bosque 1: 181 árboles ha-1, bosque abierto de P. flexuosa con Trichomaria usillo y Suaeda divaricata en ondulaciones (Bosque 2: 155 árboles ha-1, bosque abierto de P. flexuosa con T. usillo (Bosque 3: 233 árboles ha-1 y bosque abierto de P. flexuosa con A. lampa en ondulaciones suaves (Bosque 4: 215 árboles ha-1. El análisis de componentes principales de la estructura diamétrica agrupó los sitios relevados en las distintas unidades boscosas según la proporción de árboles de diámetro basal mayor a 25 cm. Los sitios del Bosque 1 (mayor proporción de árboles grandes, se separaron de los sitios con mayor proporción árboles pequeños (bosques 2 y 4. Debido al hábito de crecimiento de los algarrobos, la cantidad de productos maderables de estos bosques es baja. Además, P. flexuosa presenta en el área un porcentaje alto de individuos con más de dos fustes, la forma en muchos casos es decumbente y la altura de los fustes es menor a un metro. Por lo tanto, el potencial forestal del bosque es bajo y el posible aprovechamiento debería realizarse a escala local, considerando la inclusión de otras actividades complementarias en zonas establecidas para tal finThe recommendation of management rules that regulate the use of forest resources must be based on the knowledge of the structure and dynamics of forests.

Full Text Available This work analyses the conflict situation present in the province's drylands between goat producers and programmes to combat desertification regarding production practices and the use producers make of natural resources. The case study tackled comprises the north-eastern extreme of Mendoza province. The , which is the hyperarid spot of the region, severely affected by desertification processes, covering an extent of 10,007 km2, and with 3015 inhabitants, where small goat breeding farms predominate. Previous studies indicate that the major causes of desertification in the area are logging of the native woodland and overgrazing which have led to improper livestock production practices. In response to this, the actions to combat desertification commonly point out the need to "raise awareness" and "build capacities" of the producers by initiating processes of change in the production systems. The proposals insist that, if the current level of pressure on resources is maintained, the already serious poverty conditions will grow worse in the future. Nevertheless, despite the efforts and funds invested, the producers seem to stubbornly persist in their present production strategies and in the dynamics of natural resource use derived from them. How to explain their refusal to consider other production options likely to result in higher profit and better environmental balance? How to explain that they act, at least apparently, against their own benefits? Against the explanations that place the producers' "culture" is the most important problem, the present work seeks to cooperate in clarifying these questions through an analysis of the different rationalities that, held by different actors, converge in the area. By using a mixed methodology, the paper analyse three dimensions: 1- The environmental resource supply, which is the basis of production activities, 2- The income attained by goat production units, and 3- The expenditures they face in terms of

Full Text Available This paper provides some theses to enrich studies on the conformation and characterization of nineteenth century Argentinean ruling groups. For this purpose, the article takes as its object of study the political teams of the Mendoza province that emerged during the second half of the 19th century, and presents solid empirical evidence to identify a set of 725 political actors responsible of embodying and activating the dynamics of the provincial state. This information has been analyzed with quantitative methods and qualitative tools such as prosopography, sociological interpretations and sociability analyses, allowing us to distinguish several features of the local leadership. A wide variety of documents—official records, departmental dispatches, press of the time— was used to investigate these questions, in order to explore the variables related to the unfolding of these actors’ political careers: their socio-professional profile, their continuity or permanence in public service positions, and the projection of their itineraries. As a whole, the article constitutes a contribution to current historiographical debates about the relative complexity of the nineteenth century political system and the role of provincial and local political groups in the process of shaping the Argentine national state. This study also represents a substantive advance in regard to literature about elites and ruling teams, which has been based on meager and unsystematic data, producing hasty generalizations that have nevertheless been taken as valid indicators to define a broad political spectrum.

Energy use in the built environment is globally recognized as a key issue for sustainable urban development. In temperate-cold arid regions with a generous solar resource, such as those of western Argentina, adequate design and technology can substantially reduce the energy demand for space and water heating in urban buildings. The solar potential of low-density residential urban areas in the city of Mendoza's Metropolitan Area (MMA), has been studied earlier in this research. Several indicators of the solar potential were elaborated. They provide necessary information when planning and designing new urban structures or refurbishing existing ones. However, a more direct indicator, relating the available solar radiation during a heating season to the space volume to be heated, the Volumetric Insolation Factor (VIF), seems to be of most practical use as far as contributing a helpful evaluation indicator, to the above mentioned design processes. The present study follows the methodological steps used in the former research, evaluating comparatively the results of a Graphic-Computational Model and a Multiple Linear Regression Statistical Model. As in the earlier study, the good fit of both models' results clearly point at the reliability of the statistical procedure and its valuable contribution of a simplified calculation tool as its by-product.

[Action-oriented versus state-oriented reactions to experimenter-induced failures].

Science.gov (United States)

Brunstein, J C

1989-01-01

The present study assessed different effects of action-oriented versus state-oriented styles of coping with failure on achievement-related performance and cognition. In a learned helplessness experiment, students were exposed to an academic failure situation and were then tested on a series of problem-solving tasks, either immediately after the pretreatment or after a delay of 24 hours. Performance and cognitive concomitants were measured during both experimental periods. Results demonstrated that action orientation was associated with self-immunizing cognitions during helplessness training. Action-oriented participants improved their performance level even after repeated failure feedbacks. Moreover, action-oriented students assigned to the delayed test condition responded with increased striving for success and showed performance increments, even in comparison with control subjects. In contrast, state-oriented participants developed symptoms of helplessness and showed impaired performance during failure inductions. In later tests on problem-solving tasks, state-oriented groups responded with increased fear of failure. Independent of immediate or delayed test conditions, they soon lapsed into new performance decrements.

Energy use in the built environment is globally recognized as a key issue for sustainable urban development. In tempered-cold arid regions with a generous solar resource, adequate design and technology can substantially reduce the energy demand for space and water heating in urban buildings. This study assessed the solar potential of low-density urban environments in the city of Mendoza, Argentina. The results of the study will be used to develop technical guidelines for urban and energy planning agencies and professionals involved in the production of habitat. The study included the following successive steps: (i) selection of a representative sample of analysis units (city blocks); (ii) selection of a series of urban and building variables; (iii) definition of indicators accounting for solar masking, building's potential use of the solar radiation on the whole urban area, and availability of adequate collecting areas to satisfy high percentages of the energy demand in low-density urban environments; and (iv) insolation of potential collectors simulated by a graphic-computational model developed in the R and D unit. Only the results for solar space heating are presented in this paper. The results, direct and statistical, indicate that it is technically feasible to meet the target solar fractions. At the same time, by means of the solar recycling of existing building stocks, it is possible to considerably reduce the environmental impacts due to the extraction of materials from, and the disposal of solid wastes into, the ecosystem.

The primary visual cortex of carnivores and primates shows an orderly progression of domains of neurons that are selective to a particular orientation of visual stimuli such as bars and gratings. We recorded from single-thalamic afferent fibers that terminate in these domains to address the issue whether the orientation sensitivity of these fibers could form the basis of the remarkable orientation selectivity exhibited by most cortical cells. We first performed optical imaging of intrinsic signals to obtain a map of orientation domains on the dorsal aspect of the anaesthetized cat's area 17. After confirming using electrophysiological recordings the orientation preferences of single neurons within one or two domains in each animal, we pharmacologically silenced the cortex to leave only the afferent terminals active. The inactivation of cortical neurons was achieved by the superfusion of either kainic acid or muscimol. Responses of single geniculate afferents were then recorded by the use of high impedance electrodes. We found that the orientation preferences of the afferents matched closely with those of the cells in the orientation domains that they terminated in (Pearson's r = 0.633, n = 22, P = 0.002). This suggests a possible subcortical origin for cortical orientation selectivity. © 2015 The Authors.

Strong orientational coordinates and orientational order parameters for symmetric objects

International Nuclear Information System (INIS)

Haji-Akbari, Amir; Glotzer, Sharon C

2015-01-01

Recent advancements in the synthesis of anisotropic macromolecules and nanoparticles have spurred an immense interest in theoretical and computational studies of self-assembly. The cornerstone of such studies is the role of shape in self-assembly and in inducing complex order. The problem of identifying different types of order that can emerge in such systems can, however, be challenging. Here, we revisit the problem of quantifying orientational order in systems of building blocks with non-trivial rotational symmetries. We first propose a systematic way of constructing orientational coordinates for such symmetric building blocks. We call the arising tensorial coordinates strong orientational coordinates (SOCs) as they fully and exclusively specify the orientation of a symmetric object. We then use SOCs to describe and quantify local and global orientational order, and spatiotemporal orientational correlations in systems of symmetric building blocks. The SOCs and the orientational order parameters developed in this work are not only useful in performing and analyzing computer simulations of symmetric molecules or particles, but can also be utilized for the efficient storage of rotational information in long trajectories of evolving many-body systems.

Full Text Available El control en el intercambio de flujos energéticos interior-exterior y la inercia térmica de los materiales constructivos son características claves de la envolvente de los edificios de bodegas. Esta situación es particularmente importante en el caso de los edificios construidos sobresuelo en climas con temperaturas diarias y estacionales muy variables. En el caso de que la arquitectura no provea la respuesta adecuada, indefectiblemente se recurre al consumo de energía auxiliar. La bodega S.A., ubicada en Mendoza, Argentina, consume energía auxiliar equivalente a 2.500 kW por año. Dicha bodega sobresuelo presenta dos tipos de envolvente vertical: una tradicional en adobe (λ = 0.81W/mK y otra contemporánea en chapa galvanizada sin aislación (λ = 45 W/mK. El objetivo de este trabajo es analizar los aspectos de materialidad, inercia térmica e intercambio de flujos energéticos de envolventes tradicionales y contemporáneas y, comparar los resultados obtenidos con un caso teórico de bodega subterránea. Entre los resultados obtenidos se observa que la envolvente tradicional mantiene las temperaturas interiores entre 8,5 ºC y 10 ºC por debajo de las temperaturas exteriores, mientras que los nuevos espacios con envolventes contemporáneas lo hacen solamente 3 ºC a 5 ºC por debajo de las temperaturas exteriores. En el caso de una bodega subterránea, las temperaturas estarían estables durante el año en 16,5 ºC; esto es, en verano, 20 ºC por debajo de las temperaturas exteriores.

Full Text Available Edge effects play a key role in forest dynamics in which the context of the anthropogenic matrix has a great influence on fragment connectivity and function. The study of the interaction between edge and matrix effects in nature is essential to understand and promote the colonization of some functional groups in managed ecosystems. We studied the dynamics of 7 species of frogs and salamanders occurring in 8 ecotones of tropical montane cloud forest (TMCF which interact with adjacent managed areas of coffee and corn plantations in Guerrero, southern Mexico. A survey effort of 196 man/hours along 72 transects detected 58 individuals of 7 amphibian species and 12 environmental and structural variables were measured. The diversity and abundance of amphibians in the forest mostly depended on the matrix context adjacent to the forest patches. The forest interior provided higher relative humidity, leaf litter cover, and canopy cover that determined the presence of some amphibian species. The use of shaded coffee plantations was preferred by the amphibians over the corn plots possibly due to the maintenance of native forest arboreal elements, low management rate and less intensity of disturbance in the coffee plantations than in the corn plots. Shaded coffee plantations reduce the edge effects in TMCF, improve the connectivity between TMCF fragments and increase habitat quality for the forest interior amphibian species. Future wildlife management research should take into account edge and matrix effects to understand species dynamics which move along anthropogenic-natural ecotones in managed ecosystems, thus prioritizing sites to buffer edge effects and increase habitat quality in remaining natural ecosystems.El efecto de borde es un evento clave en la dinámica de algunos bosques, la matriz que rodea a los fragmentos de bosque tiene una gran importancia en el funcionamiento y conectividad de estos fragmentos.

In this paper, we show its applications including the determination of single crystal orientation, assistance in crystal cutting and evaluation of crystal quality. The interpretation of scanning patterns by RO-XRD on polycrystals with large grains, bulk material with several grains and oriented thin film is also presented. These results will hopefully expand the applications of the RO-XRD method and also benefit the conventional XRD techniques. (fast track communication)

Full Text Available Uno de los retos actuales a nivel de diseño y planificación urbana consiste en la trasformación de las urbes actuales en modelos de ciudades que contemplen el cuidado del medio ambiente y la mejora de la calidad de vida de los habitantes. Los estudios realizados denotan que los conglomerados de baja densidad poblacional son los más contaminantes (Cepeda y Mardaras, 2004; Norman, Maclean, Asce & Kennedy, 2006 en consecuencia una de las mejoras urbanas a fomentar es la densificación de las ciudades. No obstante, los niveles poblacionales no son únicos y estándares, sino que deben encontrarse en relación con las características propias de cada sector. Este trabajo tiene como objetivo principal desarrollar una metodología de cálculo que permita determinar niveles poblacionales máximos contemplando los requerimientos bioclimáticos de la ciudad y garantizando el acceso al sol más igualitario para todos los habitantes de la urbe. La misma es aplicada en el Área Metropolita de Mendoza y denota que las dimensiones de las manzanas y el ancho de las calles limitan la capacidad constructiva del sector y, en consecuencia, la cantidad de personas albergable. Los resultados obtenidos dan cuenta de las densidades poblaciones máximas para los distintos sectores, las que varían entre los 49 y 400 habitantes por hectárea, siendo las manzanas angostas con calles estrechas las de menor capacidad.

The investigation determined that the water contained in the aquifers is of good quality and due to the high permeability, important flows can be obtained, that guarantee the supply to the population, agriculture and industry.La zona de estudio está ubicada en el centro oeste de la provincia de Tucumán, en el noroeste de Argentina. Se extiende desde el borde oriental de la sierra de San Javier entre las localidades de Yerba Buena y el Manantial. En el piedemonte y llanura se han establecido diversos centros urbanos, agrícolas y un importante complejo industrial que se abastecen de agua subterránea. El objetivo del trabajo es delimitar los distintos factores geológicos que inciden en el comportamiento del agua subterránea y tratar de definir zonas con características hidrogeológicas apropiadas para su aprovechamiento. De esta investigación se determinó que el agua que contienen los acuíferos es de buena calidad y debido a la elevada permeabilidad de los mismos, se pueden obtener importantes caudales, con lo que se garantiza el abastecimiento a la población, agricultura e industria.

Full Text Available El territorio no irrigado del norte de la provincia de Mendoza es un vasto espacio sin acceso al bien hídrico, donde habita dispersa una población campesina de identidad originaria Huarpe. Habitar en este territorio ha sido desde hace siglos un desafío tanto al clima/ambiente como a condiciones sociopolíticas. Por lo tanto, el hábitat en tierras secas presenta particulares características respecto a su forma de gestión (autónoma, a su adaptación al ambiente y al uso de la técnica constructiva con tierra cruda: adobe. El objetivo a desarrollar aquí se sustenta en el uso actual del adobe, concebido como un vehículo que facilita la autoconstrucción y autoproducción de soluciones habitacionales en poblaciones desposeídas, ajustando su vivienda a las implicancias de un territorio árido y a un largo proceso de vulnerabilidad de derechos. Este artículo aproxima los primeros resultados de los relevamientos realizados sobre la técnica constructiva del adobe (a través de técnicas cuantitativas: encuesta y muestras in situ y las características propias del hábitat social de la población originaria Huarpe, a partir de la técnica de la observación participante.

Within plate seismicity analysis in the segment between the high Cordillera and the Precordillera of northern Mendoza (Southern Central Andes

Full Text Available Crustal seismicity in northwestern Mendoza Province in Argentina, corresponding to the transition zone between the Chilean-Pampean flat subduction zone (26.5–33.5°S and the Southern Central Andes normal subduction zone to the south, is studied in order to i identify its relationship with the mapped structure, ii determine deformational mechanisms and iii constrain the geometry of the fold and thrust belt in the lower crust. Through this, we aim to determine which are the structures that contribute to Andean construction, east of the Frontal Cordillera in Argentina and at the western Principal Cordillera in Chile. Data from a temporary local seismic network are reprocessed in order to achieve a precise location of hypocenters and, whenever possible, to build focal mechanisms. Results are interpreted and compared with previous seismic studies and structural models. Analyzed seismicity is grouped around the eastern front of Frontal Cordillera, with hypocenters mainly at depths of 25–40 km. Contrastingly, earthquakes in the Principal Cordillera to the west are located at the axial Andean sector and Chilean slope, with depths shallower than 15 km. Obtained focal mechanisms indicate mainly strike-slip displacements, left lateral at Frontal Cordillera and right lateral at Principal Cordillera. Based on these observations, new possible structural models are proposed, where seismogenic sources could be either associated with inherited basement structures from the Cuyania-Chilenia suture; or correspond to deep-blind thrusts linked with a deeper-than-previously-assumed decollement that could be shared between Frontal Cordillera and western Precordillera. This deeper decollement would coincide in turn with the one determined from receiver function analysis for the eastern Sierras Pampeanas in previous works, potentially implying a common decollement all through the fold and thrust belt configuration. Apart from this, a new interpretation of

El objetivo del trabajo fue analizar las prevalencias de sobrepeso y obesidad en niños urbanos y rurales del Departamento de San Rafael, Mendoza, en relación a las condiciones socio-ambientales. Se realizó un estudio antropométrico transversal en 1176 individuos de 6 a 12 años. Se relevaron peso corporal, talla y pliegues subcutáneos tricipital y subescapular. El sobrepeso y la obesidad fueron determinados utilizando los criterios del International Obesity Task Force. El patrón de distribución adiposa se analizó mediante el índice Subescapular/Tricipital (IST. Un valor de IST>1 indicó centralización adiposa. El relevamiento socio-ambiental se realizó mediante encuesta autoadministrada. Los datos fueron procesados por análisis de componentes principales categórico (catACP. El catACP discriminó cuatro grupos según su condición socio-ambiental: Urbano: (Alto, Medio y Empobrecido y Rural. Las prevalencias para sobrepeso fueron de 14,4% y para obesidad de 7,6%, siendo las diferencias sexuales no significativas. La población con sobrepeso presentó en ambos sexos, valores de IST<1. En los varones obesos el IST fue >1 a partir de los 9 años y en las mujeres a los 9 y 12 años. El sobrepeso se distribuyó homogéneamente en los cuatro grupos, en tanto que la obesidad fue mayor en el grupo con características rurales. Los resultados dan cuenta del creciente aumento del sobrepeso con distribución homogénea e independiente de la condición socioeconómica. La obesidad en cambio, se concentra principalmente en la zona rural.

Alkaline lavas from southern Mendoza, Argentina, extend the Patagonian DUPAL mantle field to the north

Science.gov (United States)

Soager, N.; Holm, P. M.; Llambias, E.

2010-12-01

The lavas sampled around Río Colorado ~37°S at the border of Mendoza and Neuquén provinces, Argentina, define an OIB-like end-member composition for the Pleistocene and Holocene activity in the Payún Matrú volcanic field. Although positioned in the far back-arc of the Andes, only a few lavas show signs of involvement of slab fluids or crustal contamination such as relatively high LILEs relative to Nb. The very low La/Nb (~0.66) and Zr/Nb (~5) and high U/Pb (0.3-0.4) of the end-member composition clearly distinguish the source from normal MORB mantle, while high Ba/Nb (~10) and K/Nb (370-400) compared to FOZO and HIMU type OIBs suggest an EM type of mantle. Overall, the trace element patterns of the Río Colorado lavas are similar to the central and north Patagonian intraplate basalts and to South Atlantic E-MORB affected by the Discovery plume and the LOMU component (le Roux et al., 2002, EPSL 203). The isotopic composition of the Río Colorado component has a 206Pb/204Pb = 18.4, 207Pb/204Pb = 15.58, 208Pb/204Pb = 38.3, 87Sr/86Sr = 0.70353 and 143Nd/144Nd = 0.51285. This composition overlaps the central and north Patagonian intraplate basalts in Pb-isotopic space but is slightly less enriched in Sr and Nd-isotopes. It is distinctly different from the FOZO like composition of the south Patagonian intraplate basalts and the nearby Juan Fernandéz plume but similar to the South Atlantic N-MORB and MORB from the southern Chile Ridge segment 4 (Sturm et al., 1999, JGR 104) described as DUPAL type. The DUPAL-MORB type isotopic composition and the plume-like trace element patterns of the Río Colorado lavas suggest the presence of a weak plume beneath the area. The eruption of the large Payún Matrú volcano and the gigantic Pleistocene flood basalts also calls for a thermal anomaly to produce these melts during a weakly compressive tectonic regime with no significant addition of slab fluids. This was supported by Burd et al. (2008, Abstr., 7th Int. Sym. And. Geo

In implementing time-orientated medical record (TOMR) management systems, use of a relational model played a big role. Many applications have been developed to extend query and data manipulation languages to temporal aspects of information. Our experience in developing TOMR revealed some deficiencies inside the relational model, such as: (a) abstract data type definition; (b) unified view of data, at a programming level; (c) management of temporal data; (d) management of signals and images. We identified some first topics to face by an object-orientated approach to database design. This paper describes the first steps in designing and implementing a TOMR by an object-orientated DBMS.

Sustainability Orientation and Entrepreneurship Orientation: Is There a Tradeoff Relationship between Them?

Directory of Open Access Journals (Sweden)

Chang Soo Sung

2018-02-01

Full Text Available Sustainability and entrepreneurship are often regarded as binary concepts that have a tradeoff relationship, meaning that the higher the social and environmental consideration, the lower the private and economic benefits. The purpose of this study is to investigate the effect of individual sustainability orientation on opportunity recognition and sustainable entrepreneurship intention, and examine whether it has a tradeoff relationship with entrepreneurship orientation. The result of this study shows that sustainability orientation has a positive relationship with opportunity recognition and entrepreneurship intention related to sustainability. Analysis of the moderating effects of entrepreneurship orientation reveals the positive effect with sustainability orientation but negative effect with opportunity recognition on sustainable entrepreneurship intention. This study would suggest implications to entrepreneurs on how to balance sustainability and entrepreneurship and promote sustainability entrepreneurship.

Low-temperature nuclear orientation

International Nuclear Information System (INIS)

Stone, N.J.; Postma, H.

1986-01-01

This book comprehensively surveys the many aspects of the low temperature nuclear orientation method. The angular distribution of radioactive emissions from nuclei oriented by hyperfine interactions in solids, is treated experimentally and theoretically. A general introductory chapter is followed by formal development of the theory of the orientation process and the anisotropic emission of decay products from oriented nuclei, applied to radioactive decay and to reactions. Five chapters on applications to nuclear physics cover experimental studies of alpha, beta and gamma emission, nuclear moment measurement and level structure information. Nuclear orientation studies of parity non-conservation and time reversal asymmetry are fully described. Seven chapters cover aspects of hyperfine interactions, magnetic and electric, in metals, alloys and insulating crystals, including ordered systems. Relaxation phenomena and the combined technique of NMR detection using oriented nuclei are treated at length. Chapters on the major recent development of on-line facilities, giving access to short lived nuclei far from stability, on the use of nuclear orientation for thermometry below 1 Kelvin and on technical aspects of the method complete the main text. Extensive appendices, table of relevant parameters and over 1000 references are included to assist the design of future experiments. (Auth.)

Evaluation of trauma service orientation.

Science.gov (United States)

Schott, Eric

2010-02-01

Orientation of residents to clinical services may be criticized as cumbersome, dull, and simplytoo much information. With the mandated resident-hour restrictions, the question arose: Do residents perceive the orientation to our trauma service as worthwhile? Residents attend a standardized orientation lecture on the first day of the rotation. Three weeks later, an eight-item, five-point Likert-scale survey is distributed to assess the residents' perceptions of the value of the orientation. Responses to each item were examined. Fifty-four (92%) of the residents completed the questionnaire between September 2005 and August 2006. Most indicated that orientation was helpful (85%), the Trauma Resuscitation DVD was informative (82%), the review of procedures was helpful (82%), and the instructor's knowledge was adequate (94%). Most (92%) disagreed with the statement that orientation should not be offered. Careful attention to orientation content and format is important to the perception that the orientation is worthwhile.

Despite the fact that all firms have identical roots we find that entrepreneurial orientation held by their principals affect...

Orientation-crowding within contours.

Science.gov (United States)

Glen, James C; Dakin, Steven C

2013-07-15

We examined how crowding (the breakdown of object recognition in the periphery caused by interference from "clutter") depends on the global arrangement of target and distracting flanker elements. Specifically we probed orientation discrimination using a near-vertical target Gabor flanked by two vertical distractor Gabors (one above and one below the target). By applying variable (opposite-sign) horizontal offsets to the positions of the two flankers we arranged the elements so that on some trials they formed contours with the target and on others they did not. While the presence of flankers generally elevated orientation discrimination thresholds for the target we observe maximal crowding not when flanker and targets were co-aligned but when a small spatial offset was applied to flanker location, so that contours formed between flanker and targets only when the target orientation was cued. We also report that observers' orientation judgments are biased, with target orientation appearing either attracted or repulsed by the global/contour orientation. A second experiment reveals that the sign of this effect is dependent both on observer and on eccentricity. In general, the magnitude of repulsion is reduced with eccentricity but whether this becomes attraction (of element orientation to contour orientation) is dependent on observer. We note however that across observers and eccentricities, the magnitude of repulsion correlates positively with the amount of release from crowding observed with co-aligned targets and flankers, supporting the notion of fluctuating bias as the basis for elevated crowding within contours.

Full Text Available Agent-oriented methodology (AOM is a comprehensive and unified agent methodology for agent-oriented software development. Although AOM is claimed to be able to cope with a complex system development, it is still not yet determined up to what extent this may be true. Therefore, it is vital to conduct an investigation to validate this methodology. This paper presents the adoption of AOM in developing an agent-oriented video surveillance system (VSS. An intruder handling scenario is designed and implemented through AOM. AOM provides an alternative method to engineer a distributed security system in a systematic manner. It presents the security system at a holistic view; provides a better conceptualization of agent-oriented security system and supports rapid prototyping as well as simulation of video surveillance system.

Postdictive modulation of visual orientation.

Science.gov (United States)

Kawabe, Takahiro

2012-01-01

The present study investigated how visual orientation is modulated by subsequent orientation inputs. Observers were presented a near-vertical Gabor patch as a target, followed by a left- or right-tilted second Gabor patch as a distracter in the spatial vicinity of the target. The task of the observers was to judge whether the target was right- or left-tilted (Experiment 1) or whether the target was vertical or not (Supplementary experiment). The judgment was biased toward the orientation of the distracter (the postdictive modulation of visual orientation). The judgment bias peaked when the target and distracter were temporally separated by 100 ms, indicating a specific temporal mechanism for this phenomenon. However, when the visibility of the distracter was reduced via backward masking, the judgment bias disappeared. On the other hand, the low-visibility distracter could still cause a simultaneous orientation contrast, indicating that the distracter orientation is still processed in the visual system (Experiment 2). Our results suggest that the postdictive modulation of visual orientation stems from spatiotemporal integration of visual orientation on the basis of a slow feature matching process.

The molecular orientation of π-conjugated molecules has been reported to significantly affect the performance of organic photovoltaic devices (OPVs) based on molecular films. Hence, the control of molecular orientation is a key issue toward the improvement of OPV performance. In this research, oriented thin films of an n-type molecule, 3,4,9,10-Perylenetetracarboxylic Bisbenzimida-zole (PTCBI), were formed by deposition on in-plane oriented polythiophene (PT) films. Orientation of the PTCBI films was evaluated by polarized UV-vis spectroscopy and 2D-Grazing incidence X-ray diffraction. Results indicated that PTCBI molecules on PT film exhibit nearly edge-on and in-plane orientation (with molecular long axis along the substrate), whereas PTCBI molecules without PT film exhibit neither. OPVs composed of PTCBI molecular film with and without PT were fabricated and evaluated for correlation of orientation with performance. The OPVs composed of PTCBI film with PT showed higher power conversion efficiency (PCE) than that of film without PT. The experiment indicated that in-plane orientation of PTCBI molecules absorbs incident light more efficiently, leading to increase in PCE.

The use of fiber reinforced materials such as randomly-oriented strands has grown in recent years, especially for manufacturing of aerospace composite structures. This growth is mainly due to their advantageous properties: they are lighter and more resistant to corrosion when compared to metals and are more easily shaped than continuous fiber composites. The resistance and stiffness of these materials are directly related to their fiber orientation. Thus, efficient approaches to assess their fiber orientation are in demand. In this paper, a non-destructive evaluation method is applied to assess the fiber orientation on laminates reinforced with randomly-oriented strands. More specifically, a method called pulsed thermal ellipsometry combined with an artificial neural network, a machine learning technique, is used in order to estimate the fiber orientation on the surface of inspected parts. Results showed that the method can be potentially used to inspect large areas with good accuracy and speed.

The individual-oriented and social-oriented Chinese bicultural self: testing the theory.

Science.gov (United States)

Lu, Luo

2008-06-01

The author proposes a bicultural self theory for contemporary Chinese individuals, encompassing 2 main components: the individual-oriented self and the social-oriented self. The social orientation is rooted in traditional Chinese conceptualization of the self, whereas the individual orientation has evolved and developed under Western influences along with recent societal modernization. The author conducted a series of 5 studies to test the theory and relate the model to important issues in current personality and social psychological research, such as cultural individualism-collectivism, self-construals, motivation, cognition, emotion, and well-being. A total of 977 university students in Taiwan participated. The author found that contrasting self-aspects were differentially associated with the aforementioned constructs, as theoretically predicted. This evidence thus generally supported the bicultural self model.

Orientation decoding: Sense in spirals?

Science.gov (United States)

Clifford, Colin W G; Mannion, Damien J

2015-04-15

The orientation of a visual stimulus can be successfully decoded from the multivariate pattern of fMRI activity in human visual cortex. Whether this capacity requires coarse-scale orientation biases is controversial. We and others have advocated the use of spiral stimuli to eliminate a potential coarse-scale bias-the radial bias toward local orientations that are collinear with the centre of gaze-and hence narrow down the potential coarse-scale biases that could contribute to orientation decoding. The usefulness of this strategy is challenged by the computational simulations of Carlson (2014), who reported the ability to successfully decode spirals of opposite sense (opening clockwise or counter-clockwise) from the pooled output of purportedly unbiased orientation filters. Here, we elaborate the mathematical relationship between spirals of opposite sense to confirm that they cannot be discriminated on the basis of the pooled output of unbiased or radially biased orientation filters. We then demonstrate that Carlson's (2014) reported decoding ability is consistent with the presence of inadvertent biases in the set of orientation filters; biases introduced by their digital implementation and unrelated to the brain's processing of orientation. These analyses demonstrate that spirals must be processed with an orientation bias other than the radial bias for successful decoding of spiral sense. Copyright © 2014 Elsevier Inc.

Crystal orientation dependent thermoelectric properties of highly oriented aluminum-doped zinc oxide thin films

KAUST Repository

Abutaha, Anas I.

2013-02-06

We demonstrate that the thermoelectric properties of highly oriented Al-doped zinc oxide (AZO) thin films can be improved by controlling their crystal orientation. The crystal orientation of the AZO films was changed by changing the temperature of the laser deposition process on LaAlO3 (100) substrates. The change in surface termination of the LaAlO3 substrate with temperature induces a change in AZO film orientation. The anisotropic nature of electrical conductivity and Seebeck coefficient of the AZO films showed a favored thermoelectric performance in c-axis oriented films. These films gave the highest power factor of 0.26 W m−1 K−1 at 740 K.

Machine Learning and Infrared Thermography for Fiber Orientation Assessment on Randomly-Oriented Strands Parts

Science.gov (United States)

Maldague, Xavier

2018-01-01

The use of fiber reinforced materials such as randomly-oriented strands has grown in recent years, especially for manufacturing of aerospace composite structures. This growth is mainly due to their advantageous properties: they are lighter and more resistant to corrosion when compared to metals and are more easily shaped than continuous fiber composites. The resistance and stiffness of these materials are directly related to their fiber orientation. Thus, efficient approaches to assess their fiber orientation are in demand. In this paper, a non-destructive evaluation method is applied to assess the fiber orientation on laminates reinforced with randomly-oriented strands. More specifically, a method called pulsed thermal ellipsometry combined with an artificial neural network, a machine learning technique, is used in order to estimate the fiber orientation on the surface of inspected parts. Results showed that the method can be potentially used to inspect large areas with good accuracy and speed. PMID:29351240

Full Text Available Regarding modularised software development, Aspect-oriented programming (AOP identifies and represents individually crosscutting concerns during the software development cycle’s programming stage. This article proposes and applies OOAspectZ to formal Aspect-oriented requirement specifications for prior stages of the software development cycle. It particularly concerns requirement specification and the structural design of data and behaviour, along with describing and applying Aspect-oriented UML class diagrams to designing classes, aspects and associations among classes and aspects during Aspect-oriented software development (AOSD.OOAspectZ is a language integrating both Object-Z and AspectZ formal languages whereas Aspect-oriented UML class diagrams represent AOP code, object class and crosscutting concern class structure by means of stereotypes. This article shows and applies the main OOAspectZ and AO UML class diagram characteristics to Aspect-oriented software modelling (AOSM using a classic example of AOP. Ideas for future work concerning an actual AOP version are also indicated.

fMRI orientation decoding in V1 does not require global maps or globally coherent orientation stimuli.

2013-01-01

The orientation of a large grating can be decoded from V1 functional magnetic resonance imaging (fMRI) data, even at low resolution (3-mm isotropic voxels). This finding has suggested that columnar-level neuronal information might be accessible to fMRI at 3T. However, orientation decodability might alternatively arise from global orientation-preference maps. Such global maps across V1 could result from bottom-up processing, if the preferences of V1 neurons were biased toward particular orientations (e.g., radial from fixation, or cardinal, i.e., vertical or horizontal). Global maps could also arise from local recurrent or top-down processing, reflecting pre-attentive perceptual grouping, attention spreading, or predictive coding of global form. Here we investigate whether fMRI orientation decoding with 2-mm voxels requires (a) globally coherent orientation stimuli and/or (b) global-scale patterns of V1 activity. We used opposite-orientation gratings (balanced about the cardinal orientations) and spirals (balanced about the radial orientation), along with novel patch-swapped variants of these stimuli. The two stimuli of a patch-swapped pair have opposite orientations everywhere (like their globally coherent parent stimuli). However, the two stimuli appear globally similar, a patchwork of opposite orientations. We find that all stimulus pairs are robustly decodable, demonstrating that fMRI orientation decoding does not require globally coherent orientation stimuli. Furthermore, decoding remained robust after spatial high-pass filtering for all stimuli, showing that fine-grained components of the fMRI patterns reflect visual orientations. Consistent with previous studies, we found evidence for global radial and vertical preference maps in V1. However, these were weak or absent for patch-swapped stimuli, suggesting that global preference maps depend on globally coherent orientations and might arise through recurrent or top-down processes related to the perception of

Deconstructing sexual orientation: understanding the phenomena of sexual orientation.

1997-01-01

The very terms of a debate about whether or not sexual orientation is primarily a biological phenomenon fail to consider the complex origins of the phenomenon. Deconstruction of the term "homosexuality" shows that it refers to multiple factors which cannot be studied as or subsumed under a unitary concept. Adequate understanding of sexual orientation must consider the developmental, interpersonal, experiential, and cultural dimensions of sexuality, as well as any biological contributions to sexual attraction, behavior, and identity.

Los proyectos realizados y aquellos en desarrollo, presentan un marcado énfasis regional y consideran una amplia gama de indicadores biológicos referidos a aspectos tales como las pautas de salud, nutrición, dieta y actividad de poblaciones correspondientes a distintos períodos del Holoceno. En la Región Pampeana, los trabajos bioarqueológicos llevados a cabo hasta el presente, son escasas las consideraciones sobre el sector comprendido por el Borde Occidental de la Provincia de Buenos, e inexistentes en el Sur de la Provincia de Santa Fe. El presente trabajo está orientado a analizar desde una perspectiva Bioarqueológica, la interrelación entre los procesos bioculturales y paleoambientales en distintos ambientes ecotonales de la Pampa Húmeda. Específicamente se halla abocado al análisis comparativo de sectores con características ecológicas diferentes, ya que se trata de áreas de transición, factor que probablemente influyó en la toma de decisiones por parte de los grupos humanos que habitaron la región a través del tiempo. El objetivo general es estudiar la variabilidad en los modos de uso del espacio y adaptación biocultural por parte de los pobladores de ambientes ecotonales pampeanos. La particularidad ambiental del área de estudio y la variedad del registro bioarqueológico, permiten suponer que la información generada de este modo contribuirá a aumentar y complejizar el conocimiento acerca de los procesos que estructuran el registro arqueológico a distintas escalas espaciales y temporales como un paso necesario para la comprensión de la evolución y adaptación de las poblaciones humanas.

Kinetics of oriented crystallization of polymers in the linear stress-orientation range in the series expansion approach

Directory of Open Access Journals (Sweden)

L. Jarecki

2018-04-01

Full Text Available An analytical formula is derived for the oriented crystallization coefficient governing kinetics of oriented crystallization under uniaxial amorphous orientation in the entire temperature range. A series expansion approach is applied to the free energy of crystallization in the Hoffman-Lauritzen kinetic model of crystallization at accounting for the entropy of orientation of the amorphous chains. The series expansion coefficients are calculated for systems of Gaussian chains in linear stress-orientation range. Oriented crystallization rate functions are determined basing on the ‘proportional expansion’ approach proposed by Ziabicki in the steady-state limit. Crystallization kinetics controlled by separate predetermined and sporadic primary nucleation is considered, as well as the kinetics involving both nucleation mechanisms potentially present in oriented systems. The involvement of sporadic nucleation in the transformation kinetics is predicted to increase with increasing amorphous orientation. Example computations illustrate the dependence of the calculated functions on temperature and amorphous orientation, as well as qualitative agreement of the calculations with experimental results.

Polyethylene films are a common packaging material. The level and type of chain orientation in these films are a very important property which is of great care and concern of the converter personnel during the conformation process. Usually bi-orientation is the conventional procedure but when easy tear in one direction is needed mono-orientation is sought. This paper deal with the characterization of the crystalline orientation in films of polyethylene blends (HDPE/LLDPE) which have being oriented in two steps: initially the polymer was bi-oriented via extrusion-blown, cooled, and then in a second process hot stretched along the machine direction in order to produce mono-oriented films. In order to evaluate the orientation of the film, the polarization of the FT-IR beam was rotated 360° in steps of 5° by rotating the polarizer. In each step the absorbance spectrum was recorded and the corresponding dichroic ratio (DR) calculated after subtracting the baseline. With differential scanning calorimetry (DSC) was possible to infer about the changes in the morphology caused by the stretching.

Development of symptoms-oriented operating procedures

International Nuclear Information System (INIS)

Colquhoun, R.

1984-01-01

Until recently, the formal treatment of control room procedures for upset conditions in nuclear power plants has been event-oriented. This orientation was not so much a reflection of power plant operating practice as it was a reflection of design-oriented thinking - design-basis events, therefore event-oriented procedures. Event orientation is not common in other professions. In the medical profession, for example, the stabilization of vital functions through a symptoms-oriented approach has priority over diagnosis and prognosis. The American nuclear power industry has initiated programs for the development and application of a symptoms-oriented approach for handling upset conditions. Canadian programs have independently paralleled the US programs. This article describes the rationale and current applications of the Canadian programs and identifies the relevance of a generic symptoms-based emergency procedure to current operating practices

Orientation masking and cross-orientation suppression (XOS): implications for estimates of filter bandwidth.

Science.gov (United States)

Meese, Tim S; Holmes, David J

2010-10-01

Most contemporary models of spatial vision include a cross-oriented route to suppression (masking from a broadly tuned inhibitory pool), which is most potent at low spatial and high temporal frequencies (T. S. Meese & D. J. Holmes, 2007). The influence of this pathway can elevate orientation-masking functions without exciting the target mechanism, and because early psychophysical estimates of filter bandwidth did not accommodate this, it is likely that they have been overestimated for this corner of stimulus space. Here we show that a transient 40% contrast mask causes substantial binocular threshold elevation for a transient vertical target, and this declines from a mask orientation of 0° to about 40° (indicating tuning), and then more gently to 90°, where it remains at a factor of ∼4. We also confirm that cross-orientation masking is diminished or abolished at high spatial frequencies and for sustained temporal modulation. We fitted a simple model of pedestal masking and cross-orientation suppression (XOS) to our data and those of G. C. Phillips and H. R. Wilson (1984) and found the dependency of orientation bandwidth on spatial frequency to be much less than previously supposed. An extension of our linear spatial pooling model of contrast gain control and dilution masking (T. S. Meese & R. J. Summers, 2007) is also shown to be consistent with our results using filter bandwidths of ±20°. Both models include tightly and broadly tuned components of divisive suppression. More generally, because XOS and/or dilution masking can affect the shape of orientation-masking curves, we caution that variations in bandwidth estimates might reflect variations in processes that have nothing to do with filter bandwidth.

Western Image of the Orient and Oriental in Agatha Christie’s Death on the Nile: A Postcolonial Reading

Directory of Open Access Journals (Sweden)

Mevlüde ZENGİN

2016-12-01

Full Text Available This paper attempts to read Agatha Christie’s Death on the Nile (1937, a Hercule Poirot detective novel from a postcolonial stand in general but in particular it seeks traces of Orientalism in it. Expertly plotted and set in Egypt, an exotic background, Death on the Nile is analyzed in this study, through Edward W. Said’s critique of Orientalism, to detect the novel’s projection of the Orient and oriental. Orientalism is defined by Edward Said in his groundbreaking book Orientalism (1978 as a scholarly discipline involving the negative portrayal of the East and eastern people, values and culture by westerners and as western construction of the Orient in occidental discourse through western perspective. Composed of two sections the essay begins with a brief introduction to postcolonial criticism and the critique of Orientalism. Next Death on the Nile is analyzed in the light of the criticism of Orientalism in the second section. The projection of the Orient and oriental people, places, values, concepts and so forth detected in the novel are presented in two subsections of this part. The study concludes that Death on the Nilebeing a detective novel has an orientalist quality when it comes to the reflection of the Orient and oriental though Christie does not foreground this quality of the novel. Another conclusion reached at the end of this study is that for Christie, the Queen of detective fiction has been considered to be a best-selling novelist of all time, her novel, Death on the Nile with its orientalist attitude to the East and easterner, must have contributed to the construction of a negative and false image of the Orient in western mind and discourse

2011-08-01

Full Text Available The concepts of market orientation and innovation and their interrelationship with business success have been explored from a number of perspectives. However, research in this area has not explored the differences between start-up and mature companies. The research study acquired data from over two hundred Chief Operating Officers (CEO’s and Managing Directors from both start-up and mature companies. The results illustrate the differences in both types of company and reveals new insights with regard to market orientation and its constituent elements and its relationship with both incremental and radical innovations. Key research results are that strong competitor orientation, a key ingredient of market orientation, has positive relationship to incremental innovation for start-up companies but it is contra productive for mature companies. In mature organizations a strong customer orientation is associated with radical innovation.

Research studies have differed over the importance of the relative emphasis of a customer versus competitor orientation in the development of a market orientation (Slater and Narver, 1994; Tajeddini, 2010). In this study, we assess whether the emphasis of one component over another of a market orientation is an important determinant of firm performance within the Illinois beef industry, specifically the cow-calf sector. Using a series of OLS regressions, we examine the importance of a market ...

The National Route 7 in Argentina is one of the most important corridors crossing the Andean Cordillera. It concentrates most of the traffic related to the Southern Common Market (MERCOSUR), it also connects Mendoza city (the fourth most populated in Argentina) with Santiago de Chile (the Chile capital city), and is used by tourists to access to the Aconcagua National park, Puente del Inca natural monument, skiing resorts, and to local displacements for the villages along the Mendoza valley. The road crosses the Andes through the Mendoza river valley at an elevation between 2'000 and 3'000 m. The traffic (2500 vehicles/day) is composed of motorcycles, cars and pickup trucks, trucks without trailer, buses, and semi-trailer trucks. Debris flows developed along tributaries of the Mendoza River, and due to remobilization of talus materials, impact frequently the road, causing traffic disruptions, bridges damages, etc. Rock falls detached from highly fractured outcrops also impact frequently the road, causing sometimes casualties. The aim of this study is to evaluate risk along sections of the National Road 7 develop along the Mendoza river, using a dynamic traffic simulator based on MATLAB© routine. The dynamic traffic simulator developed for natural hazards events on roads consider different scenarios based on traffic speeds, vehicle types, interactions types, road properties and natural processes. Here we show that vehicle types and traffic variations may influence the risk estimation. The analyzed risk on several critical sections of the National Route 7 demonstrates that risk may significantly increase: 1) on sinuous sections, steep sections and because of road conditions changes (exit of tunnel, bridges, road width, etc.) because of decreasing vehicle speed, particularly with semi-trailer trucks; 2) when an event, such a debris flow, occurs and generates a vehicle tailback increasing their duration presence in the risk area.

priority of the discovery in the literature, which was partly caused by the existence of the Iron Curtain. I had already enjoyed contact with Boris in the 1980s when the two volumes of Landau Level Spectroscopy were being prepared [2]. He was one of the pioneers of magneto-optics in semiconductors. In the 1950s the band structure of germanium and silicon was investigated by magneto-optical methods, mainly in the United States. No excitonic effects were observed and the band structure parameters were determined without taking account of excitons. However, working with cuprous oxide, which is a direct semiconductor with a relative large energy gap, Zakharchenya and his co-worker Seysan showed that in order to obtain correct band structure parameters, it is necessary to take excitons into account [3]. About 1970 Boris started work on optical orientation. Early work by Hanle in Germany in the 1920s on the depolarization of luminescence in mercury vapour by a transverse magnetic field was not appreciated for a long time. Only in the late 1940s did Kastler and co-workers in Paris begin a systematic study of optical pumping, which led to the award of a Nobel prize. The ideas of optical pumping were first applied by Georges Lampel to solid state physics in 1968. He demonstrated optical orientation of free carriers in silicon. The detection method was nuclear magnetic resonance; optically oriented free electrons dynamically polarized the 29Si nuclei of the host lattice. The first optical detection of spin orientation was demonstrated by with the III-V semiconductor GaSb by Parsons. Due to the various interaction mechanisms of spins with their environment, the effects occurring in semiconductors are naturally more complex than those in atoms. Optical detection is now the preferred method to detect spin alignment in semiconductors. The orientation of spins in crystals pumped with circularly polarized light is deduced from the degree of circular polarization of the recombination

Pro-Social Goals in Achievement Situations: Amity Goal Orientation Enhances the Positive Effects of Mastery Goal Orientation.

Science.gov (United States)

Levontin, Liat; Bardi, Anat

2018-04-01

Research has neglected the utility of pro-social goals within achievement situations. In this article, four studies demonstrate that amity goal orientation, promoting mutual success of oneself together with others, enhances the utility of mastery goal orientation. We demonstrate this in longitudinally predicting performance (Studies 1 and 2) and in maintaining motivation after a disappointing performance (Studies 3 and 4). The studies demonstrate the same interaction effect in academic and in work achievement contexts. Specifically, whereas amity goal orientation did not predict achievement on its own, it enhanced the positive effect of mastery goal orientation. Together, these studies establish the importance of amity goal orientation while also advancing our understanding of the effects of other achievement goal orientations. We suggest future directions in examining the utility of amity goals in other contexts.

1997-04-01

Recrystallization of heavily cold rolled aluminium and copper is studied with the aim of achieving information about effects of crystallography orientation on the growth process. The potentials of several experimental techniques are analysed, and a method well suited for characterizing growth rates of grains with different orientations is developed. This method, which is referred to as the extended Cahn-Hagel method, is used for growth rate determinations in aluminium and copper deformed and annealed under five different conditions. In all the investigated cases, preferential growth of cube oriented grains is observed. Recrystallization models, which simulates the orientational as well as microstructural development, are described. selected models are applied for studies of recrystallization in aluminium and copper under specific deformation and annealing conditions as well as for more general studies of the effects of orientation dependent growth rates on the recrystallization microstructure and texture. Finally, reasons for the observed orientation dependent growth rates are discussed. A new mechanism, orientation pinning, is suggested and it is shown that this mechanism is necessary for the understanding of experimental results. (au) 4 tabs., 41 ills., 153 refs

Factors associated with students' orientations to nursing This paper presents the results of a study focusing on the factors associated with orientations to nursing. Students' orientations to nursing have not as yet been a focus of nursing research. In some other professions, however, professional orientation has been associated with learning motivation and study performance, and has been seen as a predictor of work satisfaction. In this study, students' orientations to nursing were defined in terms of caring, nursing expertise and life orientation. The hypothesis of whether students' pre-educational experiences of nursing, gender, choice of nursing specialty, problems with nursing studies and intention to stay in nursing were associated with different orientations was tested. The extent to which students were orientated to caring, nursing expertise and their own life was also examined. The orientation to nursing measurement tool, which has been developed on the basis of a qualitative study, was used to collect the data. Nurse teachers collected the data from nursing students (n=184) who were studying in three different nursing programmes in Finland. Non-parametric assessments (Mann-Whitney U-test and Kruskal-Wallis test) of the differences between the students' orientations were carried out. A majority of the students were highly life-orientated, and two-thirds had average nursing expertise or caring orientation scores. The results supported the study hypothesis of an association between students' orientations and their gender, choice of nursing speciality, problems with nursing studies and intention to stay in nursing. However, the hypothesis of an association between students' pre-educational nursing experiences and orientation to nursing was not supported. The contradictions between students' orientation to nursing and the philosophy of nursing underlying the study programme may be a source of motivational problems and dissatisfaction with nursing education

TBV 361 RESOLUTION ANALYSIS: EMPLACEMENT DRIFT ORIENTATION

International Nuclear Information System (INIS)

Lin, M.; Kicker, D.C.; Sellers, M.D.

1999-01-01

The purpose of this To Be Verified/To Be Determined (TBX) resolution analysis is to release ''To Be Verified'' (TBV)-361 related to the emplacement drift orientation. The system design criterion in ''Subsurface Facility System Description Document'' (CRWMS M andO 1998a, p.9) specifies that the emplacement drift orientation relative to the dominant joint orientations should be at least 30 degrees. The specific objectives for this analysis include the following: (1) Collect and evaluate key block data developed for the repository host horizon rock mass. (2) Assess the dominant joint orientations based on available fracture data. (3) Document the maximum block size as a function of drift orientation. (4) Assess the applicability of the drift orientation/joint orientation offset criterion in the ''Subsurface Facility System Description Document'' (CRWMS M andO 1998a, p.9). (5) Consider the effects of seepage on drift orientation. (6) Verify that the viability assessment (VA) drift orientation complies with the drift orientation/joint orientation offset criterion, or provide justifications and make recommendations for modifying the VA emplacement drift layout. In addition to providing direct support to the System Description Document (SDD), the release of TBV-361 will provide support to the Repository Subsurface Design Department. The results from this activity may also provide data and information needs to support the MGR Requirements Department, the MGR Safety Assurance Department, and the Performance Assessment Organization

Monetary rewards influence retrieval orientations.

Halsband, Teresa M; Ferdinand, Nicola K; Bridger, Emma K; Mecklinger, Axel

2012-09-01

Reward anticipation during learning is known to support memory formation, but its role in retrieval processes is so far unclear. Retrieval orientations, as a reflection of controlled retrieval processing, are one aspect of retrieval that might be modulated by reward. These processes can be measured using the event-related potentials (ERPs) elicited by retrieval cues from tasks with different retrieval requirements, such as via changes in the class of targeted memory information. To determine whether retrieval orientations of this kind are modulated by reward during learning, we investigated the effects of high and low reward expectancy on the ERP correlates of retrieval orientation in two separate experiments. The reward manipulation at study in Experiment 1 was associated with later memory performance, whereas in Experiment 2, reward was directly linked to accuracy in the study task. In both studies, the participants encoded mixed lists of pictures and words preceded by high- or low-reward cues. After 24 h, they performed a recognition memory exclusion task, with words as the test items. In addition to a previously reported material-specific effect of retrieval orientation, a frontally distributed, reward-associated retrieval orientation effect was found in both experiments. These findings suggest that reward motivation during learning leads to the adoption of a reward-associated retrieval orientation to support the retrieval of highly motivational information. Thus, ERP retrieval orientation effects not only reflect retrieval processes related to the sought-for materials, but also relate to the reward conditions with which items were combined during encoding.

Background Approaches to measuring recovery orientation are needed, particularly for programs that may struggle with implementing recovery-oriented treatment. Objective A mixed methods comparative study was conducted to explore effective approaches to measuring recovery orientation of Assertive Community Treatment (ACT) teams. Design Two ACT teams exhibiting high and low recovery orientation were compared using surveys, treatment plan ratings, diaries of treatment visits, and team-leader-reported treatment control mechanisms. Results The recovery-oriented team differed on one survey measure (higher expectations for consumer recovery), treatment planning (greater consumer involvement and goal-directed content), and use of control mechanisms (less use of representative payee, agency-held lease, daily medication delivery, and family involvement). Staff and consumer diaries showed the most consistent differences (e.g., conveying hope and choice) and were the least susceptible to observer bias, but had the lowest response rates. Conclusions Several practices differentiate recovery orientation on ACT teams, and a mixed-methods assessment approach is feasible. PMID:23690285

Aesthetic Judgement of Orientation in Modern Art

Directory of Open Access Journals (Sweden)

George Mather

2012-01-01

Full Text Available When creating an artwork, the artist makes a decision regarding the orientation at which the work is to be hung based on their aesthetic judgement and the message conveyed by the piece. Is the impact or aesthetic appeal of a work diminished when it is hung at an incorrect orientation? To investigate this question, Experiment 1 asked whether naïve observers can appreciate the correct orientation (as defined by the artist of 40 modern artworks, some of which are entirely abstract. Eighteen participants were shown 40 paintings in a series of trials. Each trial presented all four cardinal orientations on a computer screen, and the participant was asked to select the orientation that was most attractive or meaningful. Results showed that the correct orientation was selected in 48% of trials on average, significantly above the 25% chance level, but well below perfect performance. A second experiment investigated the extent to which the 40 paintings contained recognisable content, which may have mediated orientation judgements. Recognition rates varied from 0% for seven of the paintings to 100% for five paintings. Orientation judgements in Experiment 1 correlated significantly with “meaningful” content judgements in Experiment 2: 42% of the variance in orientation judgements in Experiment 1 was shared with recognition of meaningful content in Experiment 2. For the seven paintings in which no meaningful content at all was detected, 41% of the variance in orientation judgements was shared with variance in a physical measure of image content, Fourier amplitude spectrum slope. For some paintings, orientation judgements were quite consistent, despite a lack of meaningful content. The origin of these orientation judgements remains to be identified.

Age and Value Orientations

Full Text Available The present article deals with value orientations and their role in men’s lives, particularly, in young people’s lives. This notion was introduced by the American theoretical sociologist T. Parsons, one of the creators of modern theoretical sociology. The scientist made an attempt to construct the structural and analytical theory of social action, combining personal interests (needs and aims and situation, it takes place in. The issue of value orientations remains acute for psychology. Herein we have considered several most important works, relating to the considered issue. Age aspects of young people’s value orientations are of peculiar interest to us. When analyzing this phenomenon, one should take into consideration the psychological formations, inhere for a certain age. In fact every age has its unique structure, which may change when passing from one development stage to another. Basing on this fact, we’ve considered the values, depending on the age features of the youth, relying upon the works of the scientists, working with different categories of the youth, such as: teenagers, students, children of different nationalities. It is not surprising that most scientists have come to the conclusion that the chief role in value orientation belongs to a family, originates in relations with parents and teachers. The positive reinforcement to the future develops throughout life in accordance with a lifestyle of a family, society and political situation in a state.Life orientations as a type of value orientations show different types of young people’s preferences. Value structure of its consciousness has its own specific character, depending on the age peculiarities. The dynamics of the transition from one age to another is accompanied with the reappraisal of values, eventually, influencing the life strategy of the future generation

Oriental upper blepharoplasty.

Science.gov (United States)

Weng, Chau-Jin

2009-02-01

Aesthetic surgery of the upper eyelids is a very common procedure performed in cosmetic practices around the world. The word blepharoplasty, however, has a different meaning in Asia than it does elsewhere. Orientals have different periorbital anatomic characteristics, their motivations for seeking eyelid treatment are different, and operative techniques have been adapted consequently. There are also many eyelid shapes among Orientals, mostly with regard to the presence and location of the supratarsal fold and/or presence of an epicanthal fold. The surgeon must therefore master a range of surgical procedures to treat these variations adequately. It is critical to know the indications for each blepharoplasty technique as well as their complications to select the right surgery and avoid unfavorable results. Epicanthoplasty performed on the right patient can greatly improve aesthetic results while retaining ethnic characteristics. This article will discuss Oriental eyelid characteristics, preoperative patient assessment, commonly used corrective techniques for the "double-eyelid" creation, and complications and how to avoid them.

Variations on agent-oriented programming

Full Text Available Occurrence of the agent paradigm and its further applications have stimulated the emergence of new concepts and methodologies in computer science. Today terms like multi-agent system, agent-oriented methodology, and agent-oriented programming (AOP are widely used. The aim of this paper is to clarify the validity of usage of the terms AOP and AOP language. This is disclosed in two phases of an analysis process. Determining to which concepts, terms like agent, programming, object-oriented analysis and design, object-oriented programming, and agent-oriented analysis and design correspond is accomplished in the first phase. Analysis of several known agent system engineering methodologies in terms of key concepts used, final resulting artifacts, and their relationship with known programming paradigms and modern tools for agent system development is performed in the second phase. The research shows that in most cases in the final phase of agent system design and in the coding stage, the main artifact is an object, defined according to the rules of the object-oriented paradigm. Hence, we say that the computing society still does not have AOP owing to the lack of an AOP language. Thus, the term AOP is very often incorrectly assigned to agent system development frameworks that in most cases, transform agents into objects.DOI: 10.15181/csat.v5i1.1361

Full Text Available La creación de modelos de objetos reales es una tarea compleja para la cual se ha visto que el uso de técnicas tradicionales de modelamiento tiene restricciones. Para resolver algunos de estos problemas, los sensores de rango basados en láser se usan con frecuencia para muestrear la superficie de un objeto desde varios puntos de vista, lo que resulta en un conjunto de imágenes de rango que son registradas e integradas en un modelo final triangulado. En la práctica, debido a las propiedades reflectivas de la superficie, las oclusiones, y limitaciones de acceso, ciertas áreas de la superficie del objeto usualmente no son muestreadas, dejando huecos que pueden crear efectos indeseables en el modelo integrado. En este trabajo, presentamos un nuevo algoritmo para el llenado de huecos a partir de modelos triangulados. El algoritmo comienza localizando la frontera de las regiones donde están los huecos. Un hueco consiste de un camino cerrado de bordes de los triángulos en la frontera que tienen al menos un borde que no es compartido con ningún otro triangulo. El borde del hueco es entonces adaptado mediante un B-Spline donde la variación promedio de la torsión del la aproximación del B-spline es calculada. Utilizando un simple umbral de la variación promedio a lo largo del borde, se puede clasificar automáticamente, entre huecos reales o generados por intervención humana. Siguiendo este proceso de clasificación, se usa entonces una versión automatizada del interpolador de funciones de base radial para llenar el interior del hueco usando los bordes vecinos.

Influencia del uso y gestión de la envolvente en el comportamiento térmico de verano de una vivienda en la ciudad de Mendoza, Argentina

Full Text Available En la ciudad de Mendoza, Argentina, las viviendas presentan mayoritariamente una baja calidad constructiva en relación con la falta de aislamiento de sus envolventes. Se estima que el 95% de las viviendas existentes no están aisladas en su envolvente vertical y presentan aislamiento insuficiente en techos. En un clima templado continental, con grandes amplitudes térmicas diarias y estacionales, las viviendas presentan inercia térmica como única estrategia bioclimática. En estas circunstancias, las posibilidades de gestión que ofrezca la envolvente -a través de elementos practicables y/o móviles-, son claves para la aproximación al logro del confort interior. El presente trabajo analiza la influencia del uso y gestión de las aberturas en la envolvente a cargo del usuario en una vivienda tradicional, mediante monitoreo higrotérmico, durante 59 días en verano. Para ello, se midieron dos períodos con distintas condiciones climáticas (extremas y moderadas en los que se aplicó la estrategia de ventilación natural nocturna, gracias a la cual se obtuvo 82% de horas en confort. Asimismo, se midió un período sin gestión de las aberturas en la envolvente, es decir, manteniéndolas cerradas; de lo que resultó solo un 6% de horas en confort. Se concluye, en suma, que la intervención comprometida y consciente del usuario mediante el aprovechamiento de la ventilación nocturna, en combinación con la inercia térmica del envolvente, desempeña un papel importante en el logro de condiciones térmicas en interiores que reducen el sobrecalentamiento durante el verano.

Physiological and biomechanical aspects of orienteering.

Science.gov (United States)

Creagh, U; Reilly, T

1997-12-01

Orienteering is an endurance running event which differs from other running sports both in its cognitive element and in the type of terrain encountered. The demands of overcoming this terrain are not manifest in significant differences between orienteers and road runners in somatotype, though elite female orienteers have consistently been shown to have higher levels of adiposity (> 19%) than elite road runners. High aerobic power in orienteers (up to 63 and 76 ml/kg/min in women and men, respectively) is coupled with lower anaerobic performance. While leg strength is generally not high when compared with other athletic specialties, female orienteers have relatively good leg flexion strength. The energy cost of running is greatly increased in rough terrain. Oxygen cost was 26% higher while running in a forest when compared with road running. Biomechanical differences in stride pattern contribute towards this increased demand. Despite the high energy demands during competition, orienteers pace themselves such that their mean heart rate remains within the range of 167 to 172 beats/min, despite large fluctuations. The rough terrain encountered in orienteering results not only in a high energy cost but also in a higher incidence of sport-specific injuries, particularly to the ankle. Minor injuries such as cuts and bruises are common during competition.

To empirically test the hypothetical model, we used data previously collected for 2001, and by replicating the same questionnaire now collected data for 2011. Data was analyzed by hierarchical regression analysis on the two sets of data. Our findings reveal that Croatian organizations reached the level of moderate market orientation leaving space for improvement. Findings also reveal that higher level of market orientation correlates with higher business performance. Furthermore, with development of ICT, the model of market orientation modified in time in a way that in predicting successful market oriented reaction, specific information on consumer satisfaction gains importance, while general information from competitor and consumer databases lose importance. Despite the changes in the relationships among the elements of market orientation, the model itself similarly predicts performance today as it did ten years ago. Managers are advised to increase implementation of market orientation especially focusing on market responsiveness as such behaviour will lead to better performance.

Anisotropy model for modern grain oriented electrical steel based on orientation distribution function

Directory of Open Access Journals (Sweden)

Fan Jiang

2018-05-01

Full Text Available Accurately modeling the anisotropic behavior of electrical steel is mandatory in order to perform good end simulations. Several approaches can be found in the literature for that purpose but the more often those methods are not able to deal with grain oriented electrical steel. In this paper, a method based on orientation distribution function is applied to modern grain oriented laminations. In particular, two solutions are proposed in order to increase the results accuracy. The first one consists in increasing the decomposition number of the cosine series on which the method is based. The second one consists in modifying the determination method of the terms belonging to this cosine series.

We propose a novel extension to the shape index histogram feature descriptor where the orientation of the second-order curvature is included in the histograms. The orientation of the shape index is reminiscent but not equal to gradient orientation which is widely used for feature description. We...... evaluate our new feature descriptor using a public dataset consisting of HEp-2 cell images from indirect immunoflourescence lighting. Our results show that we can improve classification performance significantly when including the shape index orientation. Notably, we show that shape index orientation...

Perceived Sexual Orientation Based on Vocal and Facial Stimuli Is Linked to Self-Rated Sexual Orientation in Czech Men

Valentova, Jaroslava Varella; Havlíček, Jan

2013-01-01

Previous research has shown that lay people can accurately assess male sexual orientation based on limited information, such as face, voice, or behavioral display. Gender-atypical traits are thought to serve as cues to sexual orientation. We investigated the presumed mechanisms of sexual orientation attribution using a standardized set of facial and vocal stimuli of Czech men. Both types of stimuli were rated for sexual orientation and masculinity-femininity by non-student heterosexual women and homosexual men. Our data showed that by evaluating vocal stimuli both women and homosexual men can judge sexual orientation of the target men in agreement with their self-reported sexual orientation. Nevertheless, only homosexual men accurately attributed sexual orientation of the two groups from facial images. Interestingly, facial images of homosexual targets were rated as more masculine than heterosexual targets. This indicates that attributions of sexual orientation are affected by stereotyped association between femininity and male homosexuality; however, reliance on such cues can lead to frequent misjudgments as was the case with the female raters. Although our study is based on a community sample recruited in a non-English speaking country, the results are generally consistent with the previous research and thus corroborate the validity of sexual orientation attributions.

Full Text Available This research aims to examine the impact of marketing orientation on the innovation level among Small and Medium Size (SMEs from Podlaskie Province. A survey utilizing a questionnaire was conducted among 137 companies in the Podlaskie Voivodeship. Altogether 3 hypotheses concerning marketing orientation and innovativeness level have been examined with the use of the hierarchical regression techniques. The relation between three types of marketing orientation and innovativeness has been analysed: customer orientation, competitor orientation and interfunctional coordination. The research results show that marketing orientation has a positive total effect on improving innovativeness. The conclusions suggest, contrary to the marketing orientation sources, that customer orientation hinder marketing innovation. A positive interrelation between customer orientation and competitor orientation, as a component of marketing orientation and innovation was supported. The positive interrelationships between inter-functional orientation and innovativeness was rejected. The study explores the relationship between marketing orientation and innovativeness, thus theoretically contributing to marketing orientation literature. Moreover, relevant ramifications are provided for management, concerning the ways to boost the level of innovativeness.

Laser Controlled Molecular Orientation Dynamics

International Nuclear Information System (INIS)

Atabek, O.

2004-01-01

Molecular orientation is a challenging control issue covering a wide range of applications from reactive collisions, high order harmonic generation, surface processing and catalysis, to nanotechnologies. The laser control scenario rests on the following three steps: (i) depict some basic mechanisms producing dynamical orientation; (ii) use them both as computational and interpretative tools in optimal control schemes involving genetic algorithms; (iii) apply what is learnt from optimal control to improve the basic mechanisms. The existence of a target molecular rotational state combining the advantages of efficient and post-pulse long duration orientation is shown. A strategy is developed for reaching such a target in terms of a train of successive short laser pulses applied at predicted time intervals. Each individual pulse imparts a kick to the molecule which orients. Transposition of such strategies to generic systems is now under investigation

Full Text Available Today’s organizations need market orientation practices to strive and generate superior performance and competitive advantage in the modern turbulent marketplace. Thus, this research inspects the respective links between the dimensions of (a competitor orientation and (b customer orientation and performance in the context of hotels in Malaysia. Data were gathered through self-administrated mail questionnaires directed to the top- and middle-level managers of three- to five-star-rated hotels in Malaysia. The findings indicated that hotels in Malaysia practiced competitor orientation and customer orientation as their core marketing strategy. Specifically, both competitor orientation and customer orientation positively linked to organizational performance. Few studies have investigated the practices and effects of market orientation on performance in the Malaysian hotel setting. Therefore, this study provided new insights into the understanding of market orientation practices in the hotel industry, particularly in Malaysia. In addition, the significance of this study, potential limitations, and future examination directions are highlighted.

A position and orientation tracking system presents a laser scanning apparatus having two measurement pods, a control station, and a detector array. The measurement pods can be mounted in the dome of a radioactive waste storage silo. Each measurement pod includes dual orthogonal laser scanner subsystems. The first laser scanner subsystem is oriented to emit a first line laser in the pan direction. The second laser scanner is oriented to emit a second line laser in the tilt direction. Both emitted line lasers scan planes across the radioactive waste surface to encounter the detector array mounted on a target robotic vehicle. The angles of incidence of the planes with the detector array are recorded by the control station. Combining measurements describing each of the four planes provides data for a closed form solution of the algebraic transform describing the position and orientation of the target robotic vehicle. 14 figs

OOC is a high-level communications protocol based on the object-oriented paradigm. OOC's syntax, semantics, and pragmatics balance simplicity and expressivity for controls environments. While natural languages are too complex, computer protocols are often insufficiently expressive. An object-oriented communications philosophy provides a base for building the necessary high-level communications primitives like I don't understand and the current value of X is K. OOC is sufficiently flexible to express data acquisition, control requests, alarm messages, and error messages in a straightforward generic way. It can be used in networks, for inter-task communication, and even for intra-task communication

The Consequences of Market Orientation on Business Performance

Full Text Available The present research aims to develop a conceptual model to test the market orientation dimensions: customer orientation, competitor orientation, interfunctional coordination, and their effects on organizational performance. The most common question found in marketing studies refers to the role assigned to the marketing concept to achieve performance. Often, companies are forced to undertake different strategic approaches to be competitive, but few companies manage to become market oriented and meet difficulties in implementing the marketing concept, because the environment in which they operate are extremely dynamic. The present empirical study utilized the results obtained by processing 121 completed questionnaires containing data from large firms that operate in Romanian. The presence of the following market orientation dimensions: customer orientation, competitor orientation and interfunctional coordination, and their consequences on organizational performance were tested using simple linear regression. The results show that the surveyed firms are market oriented and the positive consequences of this orientation dimensions on performance. The major contribution of the study is that it provides empirical proof of the effect of marketing on firm performance.

Broader visual orientation tuning in patients with schizophrenia

Directory of Open Access Journals (Sweden)

Ariel eRokem

2011-11-01

Full Text Available Reduced gamma-aminobutyric acid (GABA levels in cerebral cortex are thought to contribute to information processing deficits in patients with schizophrenia (SZ, and we have previously reported lower in vivo GABA levels in the visual cortex of patients with SZ. GABA-mediated inhibition plays a role in sharpening orientation tuning of visual cortical neurons. Therefore, we predicted that tuning for visual stimulus orientation would be wider in SZ. We measured orientation tuning with a psychophysical procedure in which subjects performed a target detection task of a low-contrast oriented grating, following adaptation to a high-contrast grating. Contrast detection thresholds were determined for a range of adapter-target orientation offsets. For both SZ and healthy controls, contrast thresholds decreased as orientation offset increased, suggesting that this tuning curve reflects the selectivity of visual cortical neurons for stimulus orientation. After accounting for generalized deficits in task performance in SZ, there was no difference between patients and controls for detection of target stimuli having either the same orientation as the adapter or orientations far from the adapter. However, patients’ thresholds were significantly higher for intermediate adapter-target offsets. In addition, the mean width parameter of a Gaussian fit to the psychophysical orientation tuning curves was significantly larger for the patient group. We also present preliminary data relating visual cortical GABA levels, as measured with magnetic resonance spectroscopy, and orientation tuning width. These results suggest that our finding of broader orientation tuning in SZ may be due to diminished visual cortical GABA levels.

Mustanski, Brian S; Bailey, J Michael; Kaspar, Sarah

2002-02-01

Both handedness and dermatoglyphic asymmetry reflect early, prenatal influences and both have been reported to be associated with male sexual orientation; handedness has been related to female sexual orientation as well. Neurohormonal and developmental perturbation are two competing hypothesis that attempt to explain these connections. We attempted to replicate these associations and to extend dermatoglyphic asymmetry findings to women. Dermatoglyphic directional asymmetry and fluctuating asymmetry were unrelated to sexual orientation. Homosexual women, but not homosexual men, had highly significant increases in non-right-handedness compared with same-sex heterosexual controls. Although this pattern of results does not allow resolution of the two competing models, it does lend additional support to a biological basis of sexual orientation.

Wise, M.A.; Fox, J.A.; Sands, R.D.

1993-12-01

In this paper, the authors discuss the experiences in creating an object-oriented economic model of the U.S. energy and agriculture markets. After a discussion of some central concepts, they provide an overview of the model, focusing on the methodology of designing an object-oriented class hierarchy specification based on standard microeconomic production functions. The evolution of the model from the class definition stage to programming it in C++, a standard object-oriented programming language, will be detailed. The authors then discuss the main differences between writing the object-oriented program versus a procedure-oriented program of the same model. Finally, they conclude with a discussion of the advantages and limitations of the object-oriented approach based on the experience in building energy-economic models with procedure-oriented approaches and languages.

A complete horizontal molecular orientation of a linear-shaped thermally activated delayed fluorescent guest emitter 2,6-bis(4-(10Hphenoxazin-10-yl)phenyl)benzo[1,2-d:5,4-d′] bis(oxazole) (cis-BOX2) was obtained in a glassy host matrix by vapor deposition. The orientational order of cis-BOX2 depended on the combination of deposition temperature and the type of host matrix. Complete horizontal orientation was obtained when a thin film with cis-BOX2 doped in a 4,4′-bis(N-carbazolyl)-1,1′-biphenyl (CBP) host matrix was fabricated at 200 K. The ultimate orientation of guest molecules originates from not only the kinetic relaxation but also the kinetic stability of the deposited guest molecules on the film surface during film growth. Utilizing the ultimate orientation, a highly efficient organic light-emitting diode with the external quantum efficiency of 33.4 ± 2.0% was realized. The thermal stability of the horizontal orientation of cis-BOX2 was governed by the glass transition temperature (T{sub g}) of the CBP host matrix; the horizontal orientation was stable unless the film was annealed above T{sub g}.

Perceptions of Sexual Orientation From Minimal Cues.

Science.gov (United States)

Rule, Nicholas O

2017-01-01

People derive considerable amounts of information about each other from minimal nonverbal cues. Apart from characteristics typically regarded as obvious when encountering another person (e.g., age, race, and sex), perceivers can identify many other qualities about a person that are typically rather subtle. One such feature is sexual orientation. Here, I review the literature documenting the accurate perception of sexual orientation from nonverbal cues related to one's adornment, acoustics, actions, and appearance. In addition to chronicling studies that have demonstrated how people express and extract sexual orientation in each of these domains, I discuss some of the basic cognitive and perceptual processes that support these judgments, including how cues to sexual orientation manifest in behavioral (e.g., clothing choices) and structural (e.g., facial morphology) signals. Finally, I attend to boundary conditions in the accurate perception of sexual orientation, such as the states, traits, and group memberships that moderate individuals' ability to reliably decipher others' sexual orientation.

Object orientation affects spatial language comprehension.

Science.gov (United States)

Burigo, Michele; Sacchi, Simona

2013-01-01

Typical spatial descriptions, such as "The car is in front of the house," describe the position of a located object (LO; e.g., the car) in space relative to a reference object (RO) whose location is known (e.g., the house). The orientation of the RO affects spatial language comprehension via the reference frame selection process. However, the effects of the LO's orientation on spatial language have not received great attention. This study explores whether the pure geometric information of the LO (e.g., its orientation) affects spatial language comprehension using placing and production tasks. Our results suggest that the orientation of the LO influences spatial language comprehension even in the absence of functional relationships. Copyright © 2013 Cognitive Science Society, Inc.

Full Text Available ABSTRACT It has been demonstrated that rootstocks can influence grape characteristics, but there are few data in literature about the rootstocks influence in the wine characteristics, especially in wines elaborated with Vitis labrusca or hybrid grapes. This study evaluated the influence of ‘IAC 766’ and ‘106-8 Mgt’ rootstocks on the physicochemical characteristics of ‘Bordô’, ‘Isabel’ and ‘IAC 138-22 ‘Máximo’ musts and wines. The musts were evaluated for pH, soluble solids, total acidity and soluble solids/acidity ratio. The wines were evaluated for density, alcohol content; total, volatile and fixed acidity; pH, dry extract, reducing sugars, reduced dry extract, alcohol in weight/reduced dry extract; free and total sulfur dioxide; anthocyanins, polyphenols index (I 280; polyphenols and total flavonoids and antioxidant activity. The ‘Bordô’, ‘Isabel’ and IAC 138-22 ‘Máximo’ musts had low soluble solids for winemaking. The ‘106-8 Mgt’ rootstock promoted higher dry extract content and reduced dry extract in Bordô wine, and lower total and fixed acidity in IAC 138-22 Máximo wine. In Isabel wine, higher pH was promoted by the ‘IAC 766’ rootstock. Aside from low total acidity of the Bordô wine, all the physicochemical characteristics of the wines studied are in accordance with Brazilian law. There was no effect of rootstocks in the phenolics content and antioxidant activity of wines.

The relative orientation between filamentary structures in molecular clouds and the ambient magnetic field provides insight into filament formation and stability. To calculate the relative orientation, a measurement of filament orientation is first required. We propose a new method to calculate the orientation of the one-pixel-wide filament skeleton that is output by filament identification algorithms such as filfinder. We derive the local filament orientation from the direction of the intensity gradient in the skeleton image using the Sobel filter and a few simple post-processing steps. We call this the “Sobel-gradient method.” The resulting filament orientation map can be compared quantitatively on a local scale with the magnetic field orientation map to then find the relative orientation of the filament with respect to the magnetic field at each point along the filament. It can also be used for constructing radial profiles for filament width fitting. The proposed method facilitates automation in analyses of filament skeletons, which is imperative in this era of “big data.”.

Orientation-Selective Retinal Circuits in Vertebrates.

Science.gov (United States)

Antinucci, Paride; Hindges, Robert

2018-01-01

Visual information is already processed in the retina before it is transmitted to higher visual centers in the brain. This includes the extraction of salient features from visual scenes, such as motion directionality or contrast, through neurons belonging to distinct neural circuits. Some retinal neurons are tuned to the orientation of elongated visual stimuli. Such 'orientation-selective' neurons are present in the retinae of most, if not all, vertebrate species analyzed to date, with species-specific differences in frequency and degree of tuning. In some cases, orientation-selective neurons have very stereotyped functional and morphological properties suggesting that they represent distinct cell types. In this review, we describe the retinal cell types underlying orientation selectivity found in various vertebrate species, and highlight their commonalities and differences. In addition, we discuss recent studies that revealed the cellular, synaptic and circuit mechanisms at the basis of retinal orientation selectivity. Finally, we outline the significance of these findings in shaping our current understanding of how this fundamental neural computation is implemented in the visual systems of vertebrates.

La Formación de Utrillas en el borde sur de la cuenca Vasco-Cantábrica: aspectos estratigráficos, mineralógicos y genéticos

Directory of Open Access Journals (Sweden)

Zuluaga, M. C.

2000-12-01

Full Text Available The Utrillas formation, located in the southem border of the Basque-Cantabrian basin, is mainly composed of sandy materials deposited in a fluvial environment. Two informal units have been distinguished due to field data: a lower coarse-grained unit, interpreted as braider river channel-fills, and a upper fine-grained unit which suggests a meandering river environment. Mineralogy consists of quartz and phyllosilicates, with minor amounts of feldspars. The analysis of tourmalines has pointed two possible sources for these sediments: granitoids and low grade-metasediments. The identified clay minerals are mica and kaolinite. Texturals observations have pointed out an inherited origin for mica, while kaolinite is partly inherited and partly authigenic. This authigenic origin seems to be associated with the alteration of potassic feldspars during the stage of late diagenesis (telodiagenesis.La Formación de Utrillas, aflorante en el borde sur de la cuenca Vasco-Cantábrica, está formada por materiales mayoritariamente areniscosos depositados en un ambiente fluvial. Los datos de campo han permitido distinguir de una manera informal dos unidades: una inferior de granulometría gruesa, representativa de un relleno de canal de tipo trenzado, y una superior más fina que sugiere un entorno de río meandriforme. La mineralogía está compuesta por cuarzo y filosilicatos, con cantidades menores de feldespatos. Como mineral accesorio aparece la turmalina, cuyo análisis ha permitido identificar dos posibles fuentes para los sedimentos: granitoides y metasedimentos de bajo grado. Los minerales de la arcilla presentes son exclusivamente la mica y la caolinita. A partir de criterios texturales, se ha constatado que la mica es de origen heredado, mientras que la caolinita es en parte heredada o bien autigénica, estando asociada a la alteración de feldespato potásico en una etapa de diagénesis tardía (telodiagénesis.

Performance implications of waste package emplacement orientation

Emplacement borehole orientation directly impacts many aspects of the Engineered Barrier System (EBS) and interactions with the near field environment. This paper considers the impacts of orientation on the hydrologic portion of the environment and its interactions with the EBS. The hydrologic environment is considered from a conceptual standpoint, the numerical analyses are left for subsequent work. As reported in this paper, several aspects of the hydrological environment are more favorable for long term performance of vertically oriented rather than horizontally oriented Waste Packages. 19 refs., 15 figs

Orientation Strategies for Aerial Oblique Images

Science.gov (United States)

Wiedemann, A.; Moré, J.

2012-07-01

Oblique aerial images become more and more distributed to fill the gap between vertical aerial images and mobile mapping systems. Different systems are on the market. For some applications, like texture mapping, precise orientation data are required. One point is the stable interior orientation, which can be achieved by stable camera systems, the other a precise exterior orientation. A sufficient exterior orientation can be achieved by a large effort in direct sensor orientation, whereas minor errors in the angles have a larger effect than in vertical imagery. The more appropriate approach is by determine the precise orientation parameters by photogrammetric methods using an adapted aerial triangulation. Due to the different points of view towards the object the traditional aerotriangulation matching tools fail, as they produce a bunch of blunders and require a lot of manual work to achieve a sufficient solution. In this paper some approaches are discussed and results are presented for the most promising approaches. We describe a single step approach with an aerotriangulation using all available images; a two step approach with an aerotriangulation only of the vertical images plus a mathematical transformation of the oblique images using the oblique cameras excentricity; and finally the extended functional model for a bundle block adjustment considering the mechanical connection between vertical and oblique images. Beside accuracy also other aspects like efficiency and required manual work have to be considered.

There has been interest in the relationship between homosexuality, gender role and suicide risk. Though homosexuals are more likely to identify as cross-gender, research has not simultaneously examined sexual orientation and gender role in assessing suicide risk. In the current study, the unique and interactive effects of sexual orientation and gender role were assessed in regard to suicidal ideation, related psychopathology and measures of coping. 77 participants were recruited from an undergraduate psychology subject pool (n=47) or from gay, lesbian and transgender student organizations (n=30) and assessed on measures of gender role, homosexuality, and psychopathology. Consistent with expectations, cross-gender role (i.e., personality traits associated with the opposite sex) is a unique predictor of suicidal symptoms. Moreover, gender role accounted for more of the overall variance in suicidal symptoms, positive problem orientation, peer acceptance and support, than sexual orientation. After accounting for gender role, sexual orientation contributed little to the variance in suicidal symptoms, associated pathology and problem-solving deficits. There was no support for gender role by sexual orientation interaction effects. The cross-sectional nature of the data limits statements regarding causality. Cross-gendered individuals, regardless of sexual orientation, appear to have higher risk for suicidal symptoms. Researchers and clinicians should assess gender role in evaluations of youth samples.

The orientation distribution of tunneling-related quantities

Seif, W. M.; Refaie, A. I.; Botros, M. M.

2018-03-01

In the nuclear tunneling processes involving deformed nuclei, most of the tunneling-related quantities depend on the relative orientations of the participating nuclei. In the presence of different multipole deformations, we study the variation of a few relevant quantities for the α-decay and the sub-barrier fusion processes, in an orientation degree of freedom. The knocking frequency and the penetration probability are evaluated within the Wentzel-Kramers-Brillouin approximation. The interaction potential is calculated with Skyrme-type nucleon-nucleon interaction. We found that the width of the potential pocket, the Coulomb barrier radius, the penetration probability, the α-decay width, and the fusion cross-section follow consistently the orientation-angle variation of the radius of the deformed nucleus. The orientation distribution patterns of the pocket width, the barrier radius, the logarithms of the penetrability, the decay width, and the fusion cross-section are found to be highly analogous to pattern of the deformed-nucleus radius. The curve patterns of the orientation angle distributions of the internal pocket depth, the Coulomb barrier height and width, as well as the knocking frequency simulate inversely the variation of the deformed nucleus radius. The predicted orientation behaviors will be of a special interest in predicting the optimum orientations for the tunneling processes.

The axiological orientation of students’ personalities

2018-03-01

Full Text Available Background. Our empirical research and analysis revealed characteristics of the axiological orientation of students’ personalities. Objective.We identified the principal types of orientation, dominant values, and attitudes of the personality in the motivational-needs sphere through a variety of validated and reliable techniques and methods. Design We understand the axiological orientation of the personality as a relatively stable set of values, motivations, needs, and moral structures produced through the lens of actions, in and through various spheres of social life, which describes complex system of a person’s perception of him-/herself, his or her perceptions of others, and his or her attitude towards work and other activities. Results. The results of the empirical research demonstrate that a set of axiological, motivational, and need characteristics form pragmatic-professional, social-communicative, or individual-egoistic types of axiological orientation of the personality, which in turn describe the subject’s attitude to the surrounding external reality and to him/herself. The pragmatic-professional type of person is dominated by values such as work, results, money, and process. The least attractive value to this type appears to be power. Respondents with a social-communicative type of axiological orientation have altruism, result and money as their main personal values. Values such as egocentrism, power, money, and freedom are a distinguishing mark of those with the individual-egoistic axiological orientation. Conclusion. This study also addresses how and through what patterns and mechanisms the axiological orientation of students’ personalities is expressed, which could enable professionals to develop educational programs aimed at harmonizing and aligning societal values and the individual’s attitudes.

Competing strategically through market orientation.

As organizations seek to better understand their customers, competitors, and environments, the marketing function effectively serves as the support mechanism for these activities in many industries. Accordingly, in many organizations the marketing concept has been elevated to the stature of a strategic weapon, manifested in the form of market orientation. Market-oriented firms emphasize the collection, organization, and dissemination of information regarding both customers and competitors. This strategy is especially well-suited for the health care industry where customer knowledge is of paramount importance, customer interaction is instantaneous, and customer satisfaction is essential. Results of a national study of general service hospitals suggest that firms which embrace a market orientation benefit through enhanced customer satisfaction and quality.

A TiO2 film has been facilely grown on a Ti foil via a general and simple acid vapor oxidation (AVO) strategy. Based on detailed characterization by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), we found that the TiO2 film was composed of anatase nanoarrays highly oriented along their direction, resulting in a large exposed {001} top surface on the film. The growth mechanism based on a topotactic transformation was proposed according to a careful study of time-dependent experimental results. Resulting from the evaluation of photocatalytic performance compared with a commercial TiO2 photocatalyst (Degussa P25), the as-prepared oriented anatase TiO2 film showed higher efficiency for degradation of atrazine and acid orange II (AOII). The performance of photocatalysis is highly relevant to the preferential orientation. The efficient photocatalysis could be attributed to the highly reactive {001} facets on the anatase nanoarrays with super-hydrophilicity.A TiO2 film has been facilely grown on a Ti foil via a general and simple acid vapor oxidation (AVO) strategy.

Steiner trees for fixed orientation metrics

Brazil, Marcus; Zachariasen, Martin

2009-01-01

We consider the problem of constructing Steiner minimum trees for a metric defined by a polygonal unit circle (corresponding to s = 2 weighted legal orientations in the plane). A linear-time algorithm to enumerate all angle configurations for degree three Steiner points is given. We provide...... a simple proof that the angle configuration for a Steiner point extends to all Steiner points in a full Steiner minimum tree, such that at most six orientations suffice for edges in a full Steiner minimum tree. We show that the concept of canonical forms originally introduced for the uniform orientation...... metric generalises to the fixed orientation metric. Finally, we give an O(s n) time algorithm to compute a Steiner minimum tree for a given full Steiner topology with n terminal leaves....

Object-oriented programming with mixins in Ada

Science.gov (United States)

Seidewitz, ED

1992-01-01

Recently, I wrote a paper discussing the lack of 'true' object-oriented programming language features in Ada 83, why one might desire them in Ada, and how they might be added in Ada 9X. The approach I took in this paper was to build the new object-oriented features of Ada 9X as much as possible on the basic constructs and philosophy of Ada 83. The object-oriented features proposed for Ada 9X, while different in detail, are based on the same kind of approach. Further consideration of this approach led me on a long reflection on the nature of object-oriented programming and its application to Ada. The results of this reflection, presented in this paper, show how a fairly natural object-oriented style can indeed be developed even in Ada 83. The exercise of developing this style is useful for at least three reasons: (1) it provides a useful style for programming object-oriented applications in Ada 83 until new features become available with Ada 9X; (2) it demystifies many of the mechanisms that seem to be 'magic' in most object-oriented programming languages by making them explicit; and (3) it points out areas that are and are not in need of change in Ada 83 to make object-oriented programming more natural in Ada 9X. In the next four sections I will address in turn the issues of object-oriented classes, mixins, self-reference and supertyping. The presentation is through a sequence of examples. This results in some overlap with that paper, but all the examples in the present paper are written entirely in Ada 83. I will return to considerations for Ada 9X in the last section of the paper.

Determinants, Moderators and Consequences of Organizational Interaction Orientation

Directory of Open Access Journals (Sweden)

Christian Hoops

2013-01-01

Full Text Available Interaction orientation reflects the ability of a company to interact with the individual customer and to gather information from successful interactions. Four dimensions of interaction orientation are identified in the literature: customer concept, interaction response capacity, customer empowerment and customer value management (Ramani and Kumar, 2008. This study shows that indeed a fifth dimension of interaction orientation exists and investigates the determinants, moderators and consequences of this construct. The first notable finding is that B2B companies exhibit a greater degree of interaction orientation than B2C firms. Ramani and Kumar hypothesized that in their study. We show that there are B2C industries such as financial services, whose companies also have a greater interaction orientation. This could be the reason why the authors could not prove their hypothesis. Furthermore, we examine the influence of strategic orientations on organizational performances and compare various orientations with each other.

Dynamics of molecular stereochemistry via oriented molecule scattering

Parker, D.H.; Jalink, H.; Stolte, S.

1987-01-01

Crossed-beam reactive scattering experiments employing electrostatic hexapole fields to control the initial collision geometry of chemical reactions are described. New results are presented on the reactions of oriented NO with ozone and oriented N 2 O with Ba. Preliminary results are also given for the oriented CH 3 F + Ca* → CaF* + CH 3 reaction. Recent technical advances in state selection and product detection are detailed. They discuss the effects of rotational coupling and nonzero impact parameters in changing the molecular precollisions orientation selected by the hexapole fields to a different in-collision orientation at the moment of impact with the reaction partner. Uncoupling of l doubling in N 2 O at strong orientation fields is demonstrated via the observed reactive anisotropy. Steric effects are found to govern many aspects of the reactions investigated thus far. Strong correlations are observed of the reactivity, product recoil, and rotational angular momentum distributions with the collisional orientation. These correlations ultimately provide information on the anisotropic part of the reaction potential energy surface. They conclude with a brief outline of possible future directions in oriented molecule scattering

Orientation effects on indexing of electron backscatter diffraction patterns

International Nuclear Information System (INIS)

Nowell, Matthew M.; Wright, Stuart I.

2005-01-01

Automated Electron Backscatter Diffraction (EBSD) has become a well-accepted technique for characterizing the crystallographic orientation aspects of polycrystalline microstructures. At the advent of this technique, it was observed that patterns obtained from grains in certain crystallographic orientations were more difficult for the automated indexing algorithms to accurately identify than patterns from other orientations. The origin of this problem is often similarities between the EBSD pattern of the correct orientation and patterns from other orientations or phases. While practical solutions have been found and implemented, the identification of these problem orientations generally occurs only after running an automated scan, as problem orientations are often readily apparent in the resulting orientation maps. However, such an approach only finds those problem orientations that are present in the scan area. It would be advantageous to identify all regions of orientation space that may present problems for automated indexing prior to initiating an automated scan, and to minimize this space through the optimization of acquisition and indexing parameters. This work presents new methods for identifying regions in orientation space where the reliability of the automated indexing is suspect prior to performing a scan. This methodology is used to characterize the impact of various parameters on the indexing algorithm

Orientational diffusion of n-alkyl cyanides

2005-01-01

Ultrafast optical Kerr effect spectroscopy has been used to study the temperature-dependent orientational dynamics of a series of nitriles with n-alkyl chains ranging from one to 11 carbons in length. In all cases the orientational diffusion is found to be described by a single-exponential decay. Analysis of the orientational correlation times using the Debye-Stokes-Einstein equation suggests that the molecules adopt extended configurations and reorient as rigid rods. The liquids with shorter alkyl chains undergo an apparent ordering transition as they are cooled

Strategies for Establishing Service Oriented Design in Organizations

Service orientation is a broadly discussed design paradigm for information systems engineering. Only recently there have been several contributions to individual dimensions of service orientation like service definition, service modeling, service management or service governance. However, a combination of useful solutions for partial problems might not constitute an effective overall approach to service orientation. We argue that the establishment of service orientation is a wicked [design] p...

The development of symptoms-oriented operating procedures

International Nuclear Information System (INIS)

Colquhoun, R.

1983-04-01

Until recently the formal treatment of control room procedures for nuclear power plant upset conditions has been event-oriented. The demise of Three Mile Island, Unit 2, caused the American industry to recognize the pitfalls inherent in relying totally on event-oriented procedures, and led to the initiation of a program for the development of a symptoms-oriented approach for handling upset conditions. The U.S. program has been independently paralleled by a Canadian program. This paper describes the development of the Canadian symptoms-oriented philosophy and identifies the relevance of a generic symptoms based emergency procedure to current operating practices

McCabe, Simon; Vail, Kenneth E; Arndt, Jamie; Goldenberg, Jamie L

2014-03-01

Interfacing the terror management health model with the meaning transfer model, we offer novel hypotheses concerning the effectiveness of celebrity and medical endorsements for consumer products and health behavior decisions. Studies 1 and 2 revealed that, compared with control topic primes, death thoughts in focal attention increased the effectiveness of health-oriented (doctor) endorsers but not culture-oriented (celebrity) endorsers, whereas death thoughts outside of focal attention increased the effectiveness of culture-oriented endorsers but not health-oriented endorsers. Studies 3 and 4 then focus more specifically on the valence and specificity of culture-oriented endorsements, revealing that death thoughts outside focal attention increase the effectiveness of culture-oriented endorsers only on the behaviors specifically endorsed and only when the endorser is characterized as possessing cultural value. Discussion focuses on everyday management of existential concerns and implications for persuasive communications in the health domain.

Are larks future-oriented and owls present-oriented? Age- and sex-related shifts in chronotype-time perspective associations.

Science.gov (United States)

Nowack, Kati; van der Meer, Elke

2013-12-01

The chronotype (morningness/eveningness) relates to individual differences in circadian preferences. Time perspective (past, present, future) refers to the preference to rely on a particular temporal frame for decision-making processes and behavior. First evidence suggests that future time perspective is associated with greater morningness and present time perspective with greater eveningness. However, little is known about how chronotype-time perspective relationships may alter over the life span. This present study investigated links between chronotype and time perspective more thoroughly by taking age and sex into account as well. Seven hundred six participants aged between 17 and 74 completed German adaptations of the Morningness--Eveningness Questionnaire (MEQ) and Zimbardo Time Perspective Inventory (ZTPI). Controlling for age and sex, relationships between morningness and future time perspective as well as between eveningness and present time perspective were replicated. These findings were supported by significant associations between time perspective and midpoint of sleep. Future time perspective was linked to earlier midpoints of sleep, indicating an early chronotype. Present time perspective was associated with later midpoints of sleep, indicating a late chronotype. However, age and sex had an impact on the chronotype-time perspective relationships. In all age groups, male larks were more future-oriented and less present-oriented, male owls more present-oriented and less future-oriented. The same conclusion could be drawn for female adolescents and young adults. For female adults above 30, there was no interrelationship between morningness and future time perspective but between eveningness and past time perspective. Female adult owls were more present-oriented as well as more past-oriented. Female adult larks were less present-oriented and less past-oriented. Findings are discussed in the light of neuroendocrine and serotonergic functioning.

Effects of Cold Rolling Reduction and Initial Goss Grains Orientation on Texture Evolution and Magnetic Performance of Ultra-thin Grain-oriented Silicon Steel

Directory of Open Access Journals (Sweden)

LIANG Rui-yang

2017-06-01

Full Text Available The ultra-thin grain-oriented silicon steel strips with a thickness of 0.06-0.12mm were produced by one-step-rolling methods with different Goss-orientation of grain-oriented silicon steel sheets. The effect of cold rolling reduction and initial Goss-orientation of samples on texture evolution and magnetic performance of ultra-thin grain-oriented silicon steel strips was studied by EBSD. The result shows that with the increase of cold rolling reduction and decrease of strips thickness, the recrystallization texture is enhanced after annealing.When the cold rolling reduction is 70%,RD//〈001〉 recrystallization texture is the sharpest, and the magnetic performance is the best. The higher degree of Goss orientation in initial sample is, the better magnetic performance of ultra-thin grain-oriented silicon steel.Therefore, for producing an ultra-thin grain-oriented silicon steel with high performance, a material with a concentrated orientation of Goss grains can be used.

Optical orientation of atoms in plasma

Energy Technology Data Exchange (ETDEWEB)

Zhitnikov, R

1979-06-01

The results are summed up of experimental work on the optical orientation of atoms in a plasma conducted by the Atomic Radiospectroscopy Group at the AN SSSR Physical Technology Institute. The main methods of forming and observing the optical orientation of atoms in a helium plasma and an alkali metal plasma are described in detail. A quantum mechanical explanation is given of all observed phenomena. The most significant results include the discovery of the effect of the optical orientation of atoms in a plasma on the plasma optical and electrical properties, such as electric conductivity, emitted light intensity, ionization degree, and electron density. The phenomenon applies generally and is inherent to plasmas of different chemical compositions, at the optical orientation of atoms of different elements. The methods are indicated of the practical application of the phenomenon in designing principally new precision quantum magnetometers.

Moessbauer effects on oriented nuclei

International Nuclear Information System (INIS)

Sayouti, E.H.

1984-01-01

Standard nuclear orientation methods (not sensitive to the polarization) do not give information on the sign of the magnetic moment. Mossbauer effect separates right-hand and left-hand circularly polarized components, thus its detection on oriented nuclei (T approximately 10 mK) gives the sign of the magnetic moment of oriented state. In this thesis we applied this method to study the 3/2 - ground states of 191 Pt and 193 Os, which are in the prolate-oblate transition region, where assignement of experimental levels to theoretical states is often umbiguous. We show that for those nuclei the sign of the magnetic moment is the signature of the configuration, and its determination establishes the correspondance between experimental and theoretical levels [fr

Radiographic film orientation in radiotherapy dosimetry

Since the discovery of x-rays, film has been used as a detection medium for radiation. More recently radiographic film has become established as a practical tool for the measurement of dose distribution in radiotherapy. The accuracy and reproducibility of film dosimetry depends on photon energy, processing conditions and film plane orientation. The relationship between photon energy, processing conditions and film dosimetry accuracy has been studied. The role of film plane orientation is still controversial. The current work aims to clarify the effects film plane orientation has on film dosimetry. Poster 205. (author)

Using goal orientations to understand motivation in strength training.

Gilson, Todd A; Chow, Graig M; Ewing, Martha E

2008-07-01

Despite the importance that today's athletics place on strength training, research exploring the motivation of athletes in this arena is sparse. It is known that not all athletes will use the same motivational cognitions as inspiration, and these differences can be explored through achievement goal orientations. Through questionnaire data and semistructured interviews, the present study investigated how collegiate athletes maintain high levels of motivation over a period of time during strength training and explored relationships among five goal orientations: task-orientation, self-enhancing ego-orientation, self-defeating ego-orientation, social-approval orientation, and work-avoidance orientation. Subjects (N = 133), comprising 90 men and 43 women, were current varsity collegiate athletes from 15 different sports at a major Midwestern university. In addition, using a screener survey to assess achievement goal orientations, 15 subjects from the sample group who demonstrated a stronger inclination to only one achievement goal orientation were interviewed to gain a more in-depth understanding of their motivation cognitions in strength training. Results showed that the strongest achievement goal orientations reported from all athletes were task-orientation and social-approval. Additionally, five higher-order themes (significant others, improvement, competitive demands, being stronger than others, and miscellaneous) were consistent among the interviewed athletes when describing how they stay motivated during strength training. Whereas all athletes were able to describe at least one motivational strategy they employed during strength training, the dominant achievement goal orientation of some athletes influenced their motivational strategy. By employing the T.A.R.G.E.T. model (), strength coaches can foster adaptive achievement goal orientations and thereby enhance intrinsic motivation for athletes engaging in strength training.

A memory advantage for past-oriented over future-oriented performance feedback.

Nash, Robert A; Winstone, Naomi E; Gregory, Samantha E A; Papps, Emily

People frequently receive performance feedback that describes how well they achieved in the past, and how they could improve in future. In educational contexts, future-oriented (directive) feedback is often argued to be more valuable to learners than past-oriented (evaluative) feedback; critically, prior research led us to predict that it should also be better remembered. We tested this prediction in six experiments. Subjects read written feedback containing evaluative and directive comments, which supposedly related to essays they had previously written (Experiments 1-2), or to essays another person had written (Experiments 3-6). Subjects then tried to reproduce the feedback from memory after a short delay. In all six experiments, the data strongly revealed the opposite effect to the one we predicted: despite only small differences in wording, evaluative feedback was in fact recalled consistently better than directive feedback. Furthermore, even when adult subjects did recall directive feedback, they frequently misremembered it in an evaluative style. These findings appear at odds with the position that being oriented toward the future is advantageous to memory. They also raise important questions about the possible behavioral effects and generalizability of such biases, in terms of students' academic performance.

2012-01-01

Hauptbeschreibung Aspect-oriented-programming is a relatively new technique that has evolved on top of the already well-established approach of object-oriented programming. When it is used correctly, it promises to remove many redundant parts of a code that appear repeatedly in an application, essentially untangling the original code. Thus, it can lead to a cleaner, more separated software design, to greater modularity and maintainability. Time-savings in software engineering can also be huge cost-savings, and anything that increases software quality is a welcome sight in an industr

Selective enhancement of orientation tuning before saccades.

Ohl, Sven; Kuper, Clara; Rolfs, Martin

2017-11-01

Saccadic eye movements cause a rapid sweep of the visual image across the retina and bring the saccade's target into high-acuity foveal vision. Even before saccade onset, visual processing is selectively prioritized at the saccade target. To determine how this presaccadic attention shift exerts its influence on visual selection, we compare the dynamics of perceptual tuning curves before movement onset at the saccade target and in the opposite hemifield. Participants monitored a 30-Hz sequence of randomly oriented gratings for a target orientation. Combining a reverse correlation technique previously used to study orientation tuning in neurons and general additive mixed modeling, we found that perceptual reports were tuned to the target orientation. The gain of orientation tuning increased markedly within the last 100 ms before saccade onset. In addition, we observed finer orientation tuning right before saccade onset. This increase in gain and tuning occurred at the saccade target location and was not observed at the incongruent location in the opposite hemifield. The present findings suggest, therefore, that presaccadic attention exerts its influence on vision in a spatially and feature-selective manner, enhancing performance and sharpening feature tuning at the future gaze location before the eyes start moving.

Orienting task effects on text recall in adulthood.

1982-09-01

This investigation examined the effects of orienting task-controlled processing on the text recall of younger (18 to 32 years), middle-aged (39 to 51 years), and older (59 to 76 years) adults. The participants were presented with a 500-word narrative text. Three groups performed orienting tasks (syntactic, stylistic, advice) within an incidental memory paradigm. A fourth group was asked for intentional recall. Analysis indicated a significant age by orienting task interaction. Younger adults recalled more propositions when recall was intentional or when it was preceded by a deep-orienting task than when it was preceded by a shallow-orienting task. Middle-aged and older adults recalled more propositions when recall was intentional than when it was incidental, regardless of the depth of the orienting task. There were no significant differences in intentional recall. In addition, a significant age x orienting task x propositional level interaction indicated that younger adults recalled more of the main ideas of the text following deep processing, whereas the middle-aged and older adults recalled more of these ideas following intentional processing.

Field-free molecular orientation of nonadiabatically aligned OCS

Science.gov (United States)

Sonoda, Kotaro; Iwasaki, Atsushi; Yamanouchi, Kaoru; Hasegawa, Hirokazu

2018-02-01

We investigate an enhancement of the orientation of OCS molecules by irradiating them with a near IR (ω) ultrashort laser pulse for alignment followed by another ultrashort laser pulse for orientation, which is synthesized by a phase-locked coherent superposition of the near IR laser pulse and its second harmonic (2ω). On the basis of the asymmetry in the ejection direction of S3+ fragment ions generated by the Coulomb explosion of multiply charged OCS, we show that the extent of the orientation of OCS is significantly enhanced when the delay between the alignment pulse and the orientation pulse is a quarter or three quarters of the rotational period. The recorded enhanced orientation was interpreted well by a numerical simulation of the temporal evolution of a rotational wave packet prepared by the alignment and orientation pulses.

Nuclear orientation experiments concerning odd-A gold isotopes

International Nuclear Information System (INIS)

Ligthart, H.J.

1982-01-01

This thesis describes nuclear spectroscopy aspects of nuclear orientation in the odd-A gold isotopes 191 Au, 193 Au, 195 Au and 197 Au. These isotopes lie in a transitional region between the spherical nuclei in the lead region and the strongly deformed rare earth isotopes. Following a general introduction to nuclear orientation, the experimental arrangement is described. A new technique is presented that applies in-beam recoil implantation inside the refrigerator itself and this was applied to the case of 191 Au. The three other gold isotopes were oriented using a conventional dilution refrigerator. The nuclear orientation experiments concerning 11/2 - isomers of the isotopes are described. The long-lived isomeric states were oriented using the large hyperfine field of gold in iron. Higher lying levels were studied by nuclear orientation of the Hg parent states. (Auth./C.F.)

Asymmetries in perception of 3D orientation.

Directory of Open Access Journals (Sweden)

Allan C Dobbins

2010-03-01

Full Text Available Visual scene interpretation depends on assumptions based on the statistical regularities of the world. People have some preference for seeing ambiguously oriented objects (Necker cubes as if tilted down or viewed from above. This bias is a near certainty in the first instant (approximately 1 s of viewing and declines over the course of many seconds. In addition, we found that there is modulation of perceived orientation that varies with position--for example objects on the left are more likely to be interpreted as viewed from the right. Therefore there is both a viewed-from-above prior and a scene position-dependent modulation of perceived 3-D orientation. These results are consistent with the idea that ambiguously oriented objects are initially assigned an orientation consistent with our experience of an asymmetric world in which objects most probably sit on surfaces below eye level.

Transgender transitioning and change of self-reported sexual orientation.

In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known.We included 115 transsexual persons (70 male-to-female "MtF" and 45 female-to-male "FtM" patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase.

Similarly, gynephilic MtF reported a change in sexual orientation more frequently than androphilic, analloerotic or bisexual MtF transsexual persons (p =0.05.In line with earlier reports, we reveal that a change in self-reported sexual orientation is frequent and does not solely occur in the context of particular transition events. Transsexual persons that are attracted by individuals of the opposite biological sex are more likely to change sexual orientation. Qualitative reports suggest that the individual's biography, autogynephilic and autoandrophilic sexual arousal, confusion before and after transitioning, social and self-acceptance, as well as concept of sexual orientation itself may explain this phenomenon.

In the past, hospitals were buffered by entry regulations and cost reimbursement; thus, they rarely dealt with traditional market pressures. But the changed terrain means that competitive factors now underscore all strategic decisions. This study examines the strategic significance of market orientation in the health care industry. The authors identified forms of market orientation by emphasizing different components, and discovered that hospitals fell into four distinct clusters or groups. They also found a critical relationship between market orientation and performance scores on a number of criteria. Finally, the authors suggest that different forms of market orientation should be employed to target specific performance measures.

The Relationship between Fashion and Style Orientation and Well-being

DEFF Research Database (Denmark)

Gwozdz, Wencke; Nielsen, Kristian S.; Gupta, Shipra

The present paper unfolds the conceptual distinction between style and fashion orientation – two trait-like orientations of clothing consumption. We relate both concepts with subjective well-being and assume a higher subjective well-being for consumers with a higher style orientation than a higher...... fashion orientation. These assumptions were tested using survey data from four countries - Germany, Poland, Sweden, and the United States - with approximately 1,000 respondents per country. Employing structural equation modelling, we found that style orientation was stronger related to subjective well......-being than fashion orientation. We further found that materialism mediated the relationship between fashion and style orientation and subjective well-being and that fashion orientation was statistically significantly stronger related to materialism than style orientation. When including materialism...

2016-09-01

Full Text Available Objective: The objective of this paper is to identify differences between measurement of organisational entrepreneurship in for-profit and non-profit context and to propose the measures aligned to non-profit organisations. The main research question is whether the scales designed to measure entrepreneurial orientation can be used in non-profit organisations and under which conditions. Research Design & Methods: Research methodology is based on review of research tools and measurement scales related to organisational entrepreneurship and comparison of for-profit and non-profit organisations, as well as their characteristics in the context of entrepreneurial orientation. Findings: Entrepreneurial orientation can be measured in non-profit organisations using existing scales that have been designed for business organisations, however they have to be modified, mostly in the dimension of competitive aggressiveness and autonomy. Additionally, the scale should be enriched with items related to cooperation with other organisations. Implications & Recommendations: It is necessary to develop methods and tools that enable the measurement of entrepreneurial orientation in non-profit organisation as well as comparative research on entrepreneurial orientation in for-profit and non-profit organisations. Contribution & Value Added: The originality of this work lies in studying some aspects of entrepreneurial orientation, that apply to the social context. Some suggestions were formulated relating to the utilisation of entrepreneurial orientation scales (originally designed for business enterprises in non-profit organisations.

Highlights: • Molecular orientation at the organic heterojunction interfaces. • Energy level alignments at the organic heterojunction interfaces. • Gap-states mediated interfacial energy level alignment. - Abstract: Due to the highly anisotropic nature of π-conjugated molecules, the molecular orientation in organic thin films can significantly affect light absorption, charge transport, energy level alignment (ELA) and hence device performance. Synchrotron-based near-edge X-ray absorption fine structure (NEXAFS) spectroscopy represents a powerful technique for probing molecular orientation. The aim of this review paper is to provide a balanced assessment on the investigation of molecular orientation at the organic–organic heterojunction (OOH) interface by NEXAFS, as well as the gap-states mediated orientation dependent energy level alignment at OOH interfaces. We highlight recent progress in elucidating molecular orientation at OOH interfaces dominated by various interfacial interactions, gap-states controlled orientation dependent energy level alignments at OOH interfaces, and the manipulations of molecular orientation and ELA in OOH.

Towards 3D crystal orientation reconstruction using automated crystal orientation mapping transmission electron microscopy (ACOM-TEM).

Science.gov (United States)

Kobler, Aaron; Kübel, Christian

2018-01-01

To relate the internal structure of a volume (crystallite and phase boundaries) to properties (electrical, magnetic, mechanical, thermal), a full 3D reconstruction in combination with in situ testing is desirable. In situ testing allows the crystallographic changes in a material to be followed by tracking and comparing the individual crystals and phases. Standard transmission electron microscopy (TEM) delivers a projection image through the 3D volume of an electron-transparent TEM sample lamella. Only with the help of a dedicated TEM tomography sample holder is an accurate 3D reconstruction of the TEM lamella currently possible. 2D crystal orientation mapping has become a standard method for crystal orientation and phase determination while 3D crystal orientation mapping have been reported only a few times. The combination of in situ testing with 3D crystal orientation mapping remains a challenge in terms of stability and accuracy. Here, we outline a method to 3D reconstruct the crystal orientation from a superimposed diffraction pattern of overlapping crystals without sample tilt. Avoiding the typically required tilt series for 3D reconstruction enables not only faster in situ tests but also opens the possibility for more stable and more accurate in situ mechanical testing. The approach laid out here should serve as an inspiration for further research and does not make a claim to be complete.

An outline of object-oriented philosophy.

Science.gov (United States)

Harman, Graham

2013-01-01

This article summarises the principles of object-oriented philosophy and explains its similarities with, and differences from, the outlook of the natural sciences. Like science, the object-oriented position avoids the notion (quite common in philosophy) that the human-world relation is the ground of all others, such that scientific statements about the world would only be statements about the world as it is for humans. But unlike science, object-oriented metaphysics treats artificial, social, and fictional entities in the same way as natural ones, and also holds that the world can only be known allusively rather than directly.

2014-07-01

Full Text Available This paper fills the gap in the research undertaken into the entrepreneurial orientation of franchisees. The study identifies entrepreneurial orientation within a defined franchise system, using the entrepreneurial character theme matrix developed by Thompson (2002. Research methodology comprises the survey approach, using electronic media and Surveypro analysis (Dillman, 2000. Hypothesis tests highlight the absence of statistically significant entrepreneurial orientation in the franchise system, despite a significant orientation in a multiple-outlet proposition analysis. Conclusions and recommendations include mobilising and communicating the action factors associated with entrepreneurial orientation, involving all franchisees within the system. Managerial implications include the motivation of developing multiple-outlet franchise systems. Future research involves broadening the data set across industries and borders.

Quality-guided orientation unwrapping for fringe direction estimation.

Science.gov (United States)

Wang, Haixia; Kemao, Qian

2012-02-01

Fringe patterns produced by various optical interferometric techniques encode information such as shape, deformation, and refractive index. Denoising and demodulation are two important procedures to retrieve information from a single closed fringe pattern. Various existing denoising and demodulation techniques require fringe direction/orientation during the processing. Fringe orientation is often easier to obtain but fringe direction is needed in some demodulation techniques. A quality-guided orientation unwrapping scheme is proposed to estimate direction from orientation. Two techniques, one based on windowed Fourier ridges and the other based on fringe gradient, are proposed for the quality-guided orientation unwrapping scheme. The direction qualities are compared for both simulated and experimental fringe patterns. Their application to demodulation technique is also given.

ORIENTATION FIELD RECONSTRUCTION OF ALTERED FINGERPRINT USING ORTHOGONAL WAVELETS

2016-11-01

Full Text Available Ridge orientation field is an important feature for fingerprint matching and fingerprint reconstruction. Matching of the altered fingerprint against its unaltered mates can be done by extracting the available features in the altered fingerprint and using it along with approximated ridge orientation. This paper presents a method for approximating ridge orientation field of altered fingerprints. In the proposed method, sine and cosine of doubled orientation of the fingerprint is decomposed using orthogonal wavelets and reconstructed back using only the approximation coefficients. No prior information about the singular points is needed for orientation approximation. The method is found suitable for orientation estimation of low quality fingerprint images also.

2018-05-01

Full Text Available Las plazas concebidas bajo el concepto de “plaza jardín” -modelo dominante en las ciudades de Latinoamérica- generan efectos microclimáticos a escala urbana y edilicia dado que actúan como fuente de enfriamiento nocturno. En contextos de baja y media densidad, dicho efecto está asociado fundamentalmente al diseño de la plaza: núcleo central predominantemente semi-sellado alrededor del cual se distribuyen áreas verdes a modo de bosques y prados. Sin embargo, en el caso de la ciudad de Mendoza-Argentina, la tendencia a la redensificación del tejido urbano, como estrategia de control del crecimiento urbano, limita los beneficios que proporcionan las configuraciones actuales de plazas. Es por ello que este trabajo evalúa el impacto de incrementar la dimensión de la plaza en el comportamiento térmico de la misma y su influencia sobre el microclima del entorno mediato, como alternativa para potenciar sus beneficios en áreas urbanas de alta densidad. Con tal fin, se seleccionaron tres casos de estudio, dos de ellos de una superficie equivalente a una manzana urbana –10000m2–, emplazados en entornos de media y alta densidad, y un caso de mayor superficie -40000m2-, inserto en un contexto de alta densidad. Tales casos fueron monitoreados térmicamente en la estación verano, durante un periodo de 21 días, mediante el uso de microadquisidores de datos del tipo HOBO H08-003-02. Se caracterizaron las condiciones radiativas a partir de la determinación del factor de visión de cielo (SVF. Los resultados obtenidos muestran que, al incrementar las dimensiones de la “plaza jardín”, sus diferentes estructuras -núcleo central, bosque, prado- presentan menores temperaturas respecto a su entorno durante todo el día. En consecuencia, constituye una estrategia eficiente para mejorar las prestaciones del espacio abierto respecto a sus efectos microclimáticos en entornos urbanos de alta densidad. Si bien dicha

Strong oriented chromatic number of planar graphs without short cycles

2008-01-01

Full Text Available Let M be an additive abelian group. A strong oriented coloringof an oriented graph G is a mapping φ from V(G to M such that (1 φ(u ≠ φ(v whenever uv is an arc in G and (2 φ(v - φ(u ≠ -(φ(t - φ(z whenever uv and zt are two arcs in G. We say that G has a M-strong-oriented coloring. The strong oriented chromatic number of an oriented graph, denoted by χ s (G, is the minimal order of a group M, such that G has M-strong-oriented coloring. This notion was introduced by Nešetřil and Raspaud. In this paper, we pose the following problem: Let i ≥ 4 be an integer. Let G be an oriented planar graph without cycles of lengths 4 to i. Which is the strong oriented chromatic number of G ? Our aim is to determine the impact of triangles on the strong oriented coloring. We give some hints of answers to this problem by proving that: (1 the strong oriented chromatic number of any oriented planar graph without cycles of lengths 4 to 12 is at most 7, and (2 the strong oriented chromatic number of any oriented planar graph without cycles of length 4 or 6 is at most 19.

2011-03-01

Dimensions of perfectionism and goal orientation have been reported to have differential relationships with test anxiety. However, the degree of inter-relationship between different dimensions of perfectionism, the 2 × 2 model of goal orientations proposed by Elliot and McGregor, cognitive test anxiety, and academic performance indicators is not known. Based on data from 134 university students, we conducted correlation and regression analyses to test associations between adaptive and maladaptive perfectionism, four types of goal orientations, cognitive test anxiety, and two indicators of academic performance: proximal cognitive performance on a word list recall test and distal academic performance in terms of grade point average. Cognitive test anxiety was inversely associated with both performance indicators, and positively associated with maladaptive perfectionism and avoidance goal orientations. Adaptive and maladaptive perfectionism accounted for significant variance in cognitive test anxiety after controlling for approach and avoidance goal orientations. Overall, nearly 50% of the variance in cognitive test anxiety could be attributed to gender, goal orientations, and perfectionism. Results suggested that students who are highly test anxious are likely to be women who endorse avoidance goal orientations and are maladaptively perfectionistic.

EFFECTS OF CUSTOMER ORIENTATION, LEARNING ORIENTATION AND INNOVATIVENESS ON HOTEL PERFORMANCE - EVIDENCE FROM CLUJ COUNTY

Stegerean Roxana

2013-07-01

Full Text Available This paper seeks to relate a strategy of diversification to inovativeness and to the performance of a hotel. Due to the more increased competition within the area of tourism e.g. hotel sector, the need of analyzing the variables mentioned in the title of the paper has become more and more obvious. The first part of the article regards the literature review for the three variables and thus, like an outcome four hypotheses are stated. The second part consists of developing findings for the studied region of Cluj County based on the presented research methodology. The results show that hotel performance is influenced by customer orientation and hotel innovativeness, while the latest one is associated in a positive manner with learning orientation. The three chosen variables could be considered real driven forces for competitiveness in the hotel sector. Thus, any management team should be aware of the results of this study and should create an appropriate environment within the organization able to sustain an expected performance level by focusing on the mentioned variables. Making a deeper analysis about the performance indicators, the results demonstrate the actual development stage of the hotel sector for Cluj County: above the national average, but with potential of growing, mainly from the perspective of efficiency. At this point, management should be aware about how significant could be innovativeness and learning orientation for creating or improving services and delivering processes. In the hotel sector it is very obvious that due to the increased role of employee the awareness is more valuable than in other sectors. Due to the most relevant market segment e.g. business tourism, the studied county is customer oriented and has a good mean value for sales goal achievement, also. In order to improve the profit goal achievement value, innovativeness and learning orientation have to be considered powerful instruments for management team. Taking

Rigorous theory of molecular orientational nonlinear optics

Kwak, Chong Hoon; Kim, Gun Yeup

2015-01-01

Classical statistical mechanics of the molecular optics theory proposed by Buckingham [A. D. Buckingham and J. A. Pople, Proc. Phys. Soc. A 68, 905 (1955)] has been extended to describe the field induced molecular orientational polarization effects on nonlinear optics. In this paper, we present the generalized molecular orientational nonlinear optical processes (MONLO) through the calculation of the classical orientational averaging using the Boltzmann type time-averaged orientational interaction energy in the randomly oriented molecular system under the influence of applied electric fields. The focal points of the calculation are (1) the derivation of rigorous tensorial components of the effective molecular hyperpolarizabilities, (2) the molecular orientational polarizations and the electronic polarizations including the well-known third-order dc polarization, dc electric field induced Kerr effect (dc Kerr effect), optical Kerr effect (OKE), dc electric field induced second harmonic generation (EFISH), degenerate four wave mixing (DFWM) and third harmonic generation (THG). We also present some of the new predictive MONLO processes. For second-order MONLO, second-order optical rectification (SOR), Pockels effect and difference frequency generation (DFG) are described in terms of the anisotropic coefficients of first hyperpolarizability. And, for third-order MONLO, third-order optical rectification (TOR), dc electric field induced difference frequency generation (EFIDFG) and pump-probe transmission are presented

During the course of sexual development, many people experience dissonance between dimensions of sexual orientation, including attraction, behavior, and identity. This study assesses the relationship between sexual orientation discordance and mental health. Data were obtained from the National Longitudinal Study of Adolescent to Adult Health (n = 8,915; female = 54.62 %; non-Hispanic black = 18.83 %, Hispanic = 14.91 %, other race (non-white) = 10.79 %). Multivariable linear regression evaluated the correlation between sexual orientation discordance and perceived stress and depressive symptomatology. Models were stratified by sex and sexual identity. Among self-identified heterosexual females and mostly heterosexual males, sexual orientation discordance predicted significantly increased depressive symptomatology. No other subpopulation demonstrated a significant correlation between sexual orientation discordance and depressive symptomatology or perceived stress. The association between sexual orientation discordance and depressive symptomatology suggests a link between sexuality, self-concept, and mental health.

Effective design of health information technology (HIT) for patient-centered care requires consideration of workflow from the patient's perspective, termed 'patient-oriented workflow.' This approach organizes the building blocks of work around the patients who are moving through the care system. Patient-oriented workflow complements the more familiar clinician-oriented workflow approaches, and offers several advantages, including the ability to capture simultaneous, cooperative work, which is essential in care delivery. Patient-oriented workflow models can also provide an understanding of healthcare work taking place in various formal and informal health settings in an integrated manner. We present two cases demonstrating the potential value of patient-oriented workflow models. Significant theoretical, methodological, and practical challenges must be met to ensure adoption of patient-oriented workflow models. Patient-oriented workflow models define meaningful system boundaries and can lead to HIT implementations that are more consistent with cooperative work and its emergent features.

However, companies are part of value chains, and a lot of competition taking place...... in international markets is between the different value chains rather than between the individual companies. This is the reason why it makes more sense to look at the degree of market orientation in a complete value chain rather than the degree of market orientation of a single company....

In order to use the object-oriented mature tools and language in software process model, make the software process model more accord with the industrial standard, it’s necessary to study the object-oriented modelling of software process. Based on the formal process definition in EPMM, considering the characteristics that Petri net is mainly formal modelling tool and combining the Petri net modelling with the object-oriented modelling idea, this paper provides this implementation method to convert EPMM based on Petri net into object models based on object-oriented description.

Long range position and orientation tracking system

1995-01-01

The long range position and orientation tracking system (LRPOTS) will consist of two measurement pods, a VME-based computer system, and a detector array. The system is used to measure the position and orientation of a target that may be attached to a robotic arm, teleoperated manipulator, or autonomous vehicle. The pods have been designed to be mounted in the man-ways of the domes of the Fernald K-65 waste silos. Each pod has two laser scanner subsystems as well as lights and camera systems. One of the laser scanners will be oriented to scan in the pan direction, the other in the tilt direction. As the lasers scan across the detector array, the angles of incidence with each detector are recorded. Combining measurements from each of the four lasers yields sufficient data for a closed-form solution of the transform describing the location and orientation of the Content Mobilization System (CMS). Redundant detectors will be placed on the CMS to accommodate occlusions, to provide improved measurement accuracy, and to determine the CMS orientation

Promoting students' future orientation is inherently a goal of the educational system. Recently, it has received more explicit attention given the increased focus on career readiness. This study aimed to examine the association between school climate and adolescents' report of future orientation using data from youth (N = 27,698; 49.4 % female) across 58 high schools. Three-level hierarchical linear models indicated that perceptions of available emotional and service supports, rules and consequences, and parent engagement were positively related to adolescents' future orientation. Additionally, the school-level average future orientation was significantly related to individuals' future orientation, indicating a potential influence of contextual effects on this construct. Taken together, these findings suggest that interventions targeting school climate may hold promise for promoting future orientation.

Sun-Compass Orientation in Mediterranean Fish Larvae.

Faillettaz, Robin; Blandin, Agathe; Paris, Claire B; Koubbi, Philippe; Irisson, Jean-Olivier

2015-01-01

Mortality is very high during the pelagic larval phase of fishes but the factors that determine recruitment success remain unclear and hard to predict. Because of their bipartite life history, larvae of coastal species have to head back to the shore at the end of their pelagic episode, to settle. These settlement-stage larvae are known to display strong sensory and motile abilities, but most work has been focused on tropical, insular environments and on the influence of coast-related cues on orientation. In this study we quantified the in situ orientation behavior of settlement-stage larvae in a temperate region, with a continuous coast and a dominant along-shore current, and inspected both coast-dependent and independent cues. We tested six species: one Pomacentridae, Chromis chromis, and five Sparidae, Boops boops, Diplodus annularis, Oblada melanura, Spicara smaris and Spondyliosoma cantharus. Over 85% of larvae were highly capable of keeping a bearing, which is comparable to the orientation abilities of tropical species. Sun-related cues influenced the precision of bearing-keeping at individual level. Three species, out of the four tested in sufficient numbers, oriented significantly relative to the sun position. These are the first in situ observations demonstrating the use of a sun compass for orientation by wild-caught settlement-stage larvae. This mechanism has potential for large-scale orientation of fish larvae globally.

2011-06-01

Vocational orientation in medical rehabilitation has become an important issue in rehabilitation science and practice in Germany. Although a variety of vocationally oriented interventions has been developed in recent years, there is still a lack of consensus with regard to the definition of specific types of interventions as well as relevant criteria (e. g., methods; instruments; duration/frequency; patient groups). Building on preliminary definitions, basic types of vocationally oriented measures/interventions were conceptually modified and refined in the context of a consensual process. 39 experts of various professions were contacted during a 2-stage Delphi survey to evaluate existing definitions of vocationally oriented interventions using key questions. Standardized descriptions of 5 vocationally oriented basic interventions were specified in cooperation with an interdisciplinary panel of experts. Descriptions were published in a workbook and a homepage for researchers and clinicians, which also contain information on the implementation of measures into rehabilitative care as well as good practice examples. The media developed in this project may contribute to the transfer of research results on vocationally oriented rehabilitation into health care practice. © Georg Thieme Verlag KG Stuttgart · New York.

Synthesised model of market orientation-business performance relationship

2006-12-01

Full Text Available Purpose: The purpose of this paper is to assess the impact of market orientation on the performance of the organisation. While much empirical works have centered on market orientation, the generalisability of its impact on performance of the Food and Beverages organisations in the Nigeria context has been under-researched. Design/Methodology/Approach: The study adopted a triangulation methodology (quantitative and qualitative approach. Data was collected from key informants using a research instrument. Returned instruments were analyzed using nonparametric correlation through the use of the Statistical Package for Social Sciences (SPSS version 10. Findings: The study validated the earlier instruments but did not find any strong association between market orientation and business performance in the Nigerian context using the food and beverages organisations for the study. The reasons underlying the weak relationship between market orientation and business performance of the Food and Beverages organisations is government policies, new product development, diversification, innovation and devaluation of the Nigerian currency. One important finding of this study is that market orientation leads to business performance through some moderating variables. Implications: The study recommends that Nigerian Government should ensure a stable economy and make economic policies that will enhance existing business development in the country. Also, organisations should have performance measurement systems to detect the impact of investment on market orientation with the aim of knowing how the organisation works. Originality/Value: This study significantly refines the body of knowledge concerning the impact of market orientation on the performance of the organisation, and thereby offers a model of market orientation and business performance in the Nigerian context for marketing scholars and practitioners. This model will, no doubt, contribute to the body of

Oriented matroids—combinatorial structures underlying loop quantum gravity

Science.gov (United States)

Brunnemann, Johannes; Rideout, David

2010-10-01

We analyze combinatorial structures which play a central role in determining spectral properties of the volume operator (Ashtekar A and Lewandowski J 1998 Adv. Theor. Math. Phys. 1 388) in loop quantum gravity (LQG). These structures encode geometrical information of the embedding of arbitrary valence vertices of a graph in three-dimensional Riemannian space and can be represented by sign strings containing relative orientations of embedded edges. We demonstrate that these signature factors are a special representation of the general mathematical concept of an oriented matroid (Ziegler G M 1998 Electron. J. Comb.; Björner A et al 1999 Oriented Matroids (Cambridge: Cambridge University Press)). Moreover, we show that oriented matroids can also be used to describe the topology (connectedness) of directed graphs. Hence, the mathematical methods developed for oriented matroids can be applied to the difficult combinatorics of embedded graphs underlying the construction of LQG. As a first application we revisit the analysis of Brunnemann and Rideout (2008 Class. Quantum Grav. 25 065001 and 065002), and find that enumeration of all possible sign configurations used there is equivalent to enumerating all realizable oriented matroids of rank 3 (Ziegler G M 1998 Electron. J. Comb.; Björner A et al 1999 Oriented Matroids (Cambridge: Cambridge University Press)), and thus can be greatly simplified. We find that for 7-valent vertices having no coplanar triples of edge tangents, the smallest non-zero eigenvalue of the volume spectrum does not grow as one increases the maximum spin jmax at the vertex, for any orientation of the edge tangents. This indicates that, in contrast to the area operator, considering large jmax does not necessarily imply large volume eigenvalues. In addition we give an outlook to possible starting points for rewriting the combinatorics of LQG in terms of oriented matroids.

Now, in many firms, MO is treated like the marketing concept. This traditional view of MO has two main drawbacks: first of all it overlooks market actors other than customer (i.e. distributors, competitors and prescribers). Then, this functional perspective leads to confine the concept of MO to the activities generally conducted ...

Orientation estimation algorithm applied to high-spin projectiles

International Nuclear Information System (INIS)

Long, D F; Lin, J; Zhang, X M; Li, J

2014-01-01

High-spin projectiles are low cost military weapons. Accurate orientation information is critical to the performance of the high-spin projectiles control system. However, orientation estimators have not been well translated from flight vehicles since they are too expensive, lack launch robustness, do not fit within the allotted space, or are too application specific. This paper presents an orientation estimation algorithm specific for these projectiles. The orientation estimator uses an integrated filter to combine feedback from a three-axis magnetometer, two single-axis gyros and a GPS receiver. As a new feature of this algorithm, the magnetometer feedback estimates roll angular rate of projectile. The algorithm also incorporates online sensor error parameter estimation performed simultaneously with the projectile attitude estimation. The second part of the paper deals with the verification of the proposed orientation algorithm through numerical simulation and experimental tests. Simulations and experiments demonstrate that the orientation estimator can effectively estimate the attitude of high-spin projectiles. Moreover, online sensor calibration significantly enhances the estimation performance of the algorithm. (paper)

Thermoregulatory behavior and orientation preference in bearded dragons.

Science.gov (United States)

Black, Ian R G; Tattersall, Glenn J

2017-10-01

The regulation of body temperature is a critical function for animals. Although reliant on ambient temperature as a heat source, reptiles, and especially lizards, make use of multiple voluntary and involuntary behaviors to thermoregulate, including postural changes in body orientation, either toward or away from solar sources of heat. This thermal orientation may also result from a thermoregulatory drive to maintain precise control over cranial temperatures or a rostrally-driven sensory bias. The purpose of this work was to examine thermal orientation behavior in adult and neonatal bearded dragons (Pogona vitticeps), to ascertain its prevalence across different life stages within a laboratory situation and its interaction with behavioral thermoregulation. Both adult and neonatal bearded dragons were placed in a thermal gradient and allowed to voluntarily select temperatures for up to 8h to observe the presence and development of a thermoregulatory orientation preference. Both adult and neonatal dragons displayed a non-random orientation, preferring to face toward a heat source while achieving mean thermal preferences of ~ 33-34°C. Specifically, adult dragons were more likely to face a heat source when at cooler ambient temperatures and less likely at warmer temperatures, suggesting that orientation behavior counter-balances local selected temperatures but contributes to their thermoregulatory response. Neonates were also more likely to select cooler temperatures when facing a heat source, but required more experience before this orientation behavior emerged. Combined, these results demonstrate the importance of orientation to behavioral thermoregulation in multiple life stages of bearded dragons. Copyright © 2017 Elsevier Ltd. All rights reserved.

However, because of the culture and religion differences backgrounds, Indonesians have given this issue various responses. In general, Indonesian public opinion on LGBT are split into two different groups, one minority group is proponent to present of LGBT and any things related to it, and another majority groups are opponent. Objective of this editorial is to discuss how sexual orientation develop from prenatal until emerging of clinical manifestation in adulthood, by no mean to support either group. Otherwise, to give more insight about how male and female get their appropriate sexual orientations and why some of them get inappropriate sexual orientations.

Minireview: Hormones and human sexual orientation.

Balthazart, Jacques

2011-08-01

Many people believe that sexual orientation (homosexuality vs. heterosexuality) is determined by education and social constraints. There are, however, a large number of studies indicating that prenatal factors have an important influence on this critical feature of human sexuality. Sexual orientation is a sexually differentiated trait (over 90% of men are attracted to women and vice versa). In animals and men, many sexually differentiated characteristics are organized during early life by sex steroids, and one can wonder whether the same mechanism also affects human sexual orientation. Two types of evidence support this notion. First, multiple sexually differentiated behavioral, physiological, or even morphological traits are significantly different in homosexual and heterosexual populations. Because some of these traits are known to be organized by prenatal steroids, including testosterone, these differences suggest that homosexual subjects were, on average, exposed to atypical endocrine conditions during development. Second, clinical conditions associated with significant endocrine changes during embryonic life often result in an increased incidence of homosexuality. It seems therefore that the prenatal endocrine environment has a significant influence on human sexual orientation but a large fraction of the variance in this behavioral characteristic remains unexplained to date. Genetic differences affecting behavior either in a direct manner or by changing embryonic hormone secretion or action may also be involved. How these biological prenatal factors interact with postnatal social factors to determine life-long sexual orientation remains to be determined.

Magnetic compass orientation in the European eel.

Caroline M F Durif

Full Text Available European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (~ 6000 km and orientation mechanisms are unknown. Several attempts have been made to prove the existence of magnetoreception in Anguilla sp., but none of these studies have demonstrated magnetic compass orientation in earth-strength magnetic field intensities. We tested eels in four altered magnetic field conditions where magnetic North was set at geographic North, South, East, or West. Eels oriented in a manner that was related to the tank in which they were housed before the test. At lower temperature (under 12°C, their orientation relative to magnetic North corresponded to the direction of their displacement from the holding tank. At higher temperatures (12-17°C, eels showed bimodal orientation along an axis perpendicular to the axis of their displacement. These temperature-related shifts in orientation may be linked to the changes in behavior that occur between the warm season (during which eels are foraging and the colder fall and winter (during which eels undertake their migrations. These observations support the conclusion that 1. eels have a magnetic compass, and 2. they use this sense to orient in a direction that they have registered moments before they are displaced. The adaptive advantage of having a magnetic compass and learning the direction in which they have been displaced becomes clear when set in the context of the eel's seaward migration. For example, if their migration is halted or blocked, as it is the case when environmental conditions become unfavorable or when they encounter a barrier, eels would be able to resume their movements along their old bearing when conditions become favorable again or when they pass by the barrier.

INCORPORATING MARKET ORIENTATION IN HIGHER EDUCATION INSTITUTIONS

Directory of Open Access Journals (Sweden)

Gordan Camelia

2013-07-01

Full Text Available The purpose of this paper is to provide a review of the main issues surrounding the concept of market orientation applied in the context of higher education. Considering the important changes taking place in this sector, a strong willingness of universities to adopt marketing concepts can be noticed. The paper seeks to provide a retrospect on this process, starting with the incorporation of marketing in higher education, and moving on to its implementation, which has come to be known as market orientation. Following a stream of the most relevant literature in the field, we present definitions of the main concepts, and integrate them in the education context, with the purpose of establishing the relevance and importance of market orientation for achieving a sustainable competitive advantage and higher institutional performance. The paper does not aim at providing an exhaustive literature review, but rather at presenting the main elements that define a market orientation, and at supporting its implementation, by outlining the significant benefits that could follow. While theoretical by nature, this research contributes to the body of literature in the field, through closely examining the conceptualization and operationalization of market orientation, and also providing the fundamental components that define the concept and help its implementation. Furthermore, the paper provides practitioners with a number of suggested research directions, which could potentially help improve educational institutions’ activity, while also contributing to a better understanding of the concept, and to building richer theories in the field of marketing education. Given that the marketing literature in Romania has mostly overlooked market orientation, both this paper, and all following research in this area will prove to be significant for education managers and researchers alike, promoting the importance and significance of relevant knowledge, and encouraging a

Direct encoding of orientation variance in the visual system.

Norman, Liam J; Heywood, Charles A; Kentridge, Robert W

2015-01-01

Our perception of regional irregularity, an example of which is orientation variance, seems effortless when we view two patches of texture that differ in this attribute. Little is understood, however, of how the visual system encodes a regional statistic like orientation variance, but there is some evidence to suggest that it is directly encoded by populations of neurons tuned broadly to high or low levels. The present study shows that selective adaptation to low or high levels of variance results in a perceptual aftereffect that shifts the perceived level of variance of a subsequently viewed texture in the direction away from that of the adapting stimulus (Experiments 1 and 2). Importantly, the effect is durable across changes in mean orientation, suggesting that the encoding of orientation variance is independent of global first moment orientation statistics (i.e., mean orientation). In Experiment 3 it was shown that the variance-specific aftereffect did not show signs of being encoded in a spatiotopic reference frame, similar to the equivalent aftereffect of adaptation to the first moment orientation statistic (the tilt aftereffect), which is represented in the primary visual cortex and exists only in retinotopic coordinates. Experiment 4 shows that a neuropsychological patient with damage to ventral areas of the cortex but spared intact early areas retains sensitivity to orientation variance. Together these results suggest that orientation variance is encoded directly by the visual system and possibly at an early cortical stage.

This study aims to develop and evaluate a new Health-oriented Electronic Oral Health Record that implements the health-oriented status and intervention index. The index takes the principles of holistic oral healthcare and applies them to the design and implementation of the Health-oriented Electronic Oral Health Record. We designed an experiment using focus groups and a consensus (Delphi process) method to develop a new health-oriented status and intervention index and graphical user interface. A comparative intervention study with qualitative and quantitative methods was used to compare an existing Electronic Oral Health Record to the Health-oriented Electronic Oral Health Record, focusing on dentist satisfaction, accuracy, and completeness of oral health status recording. The study was conducted by the dental staff of the Inter-country Center for Oral Health collaborative hospitals in Thailand. Overall, the user satisfaction questionnaire had a positive response to the Health-oriented Electronic Oral Health Record. The dentists found it easy to use and were generally satisfied with the impact on their work, oral health services, and surveillance. The dentists were significantly satisfied with the Health-oriented Electronic Oral Health Record compared to the existing Electronic Oral Health Record (p health information recorded using the Health-oriented Electronic Oral Health Record were 97.15 and 93.74 percent, respectively. This research concludes that the Health-oriented Electronic Oral Health Record satisfied many dentists, provided benefits to holistic oral healthcare, and facilitated the planning, managing, and evaluation of the healthcare delivery system.

The Faculty Development Committee (FDC) at Baylor College of Dentistry (BCD) is charged with providing programs and activities that facilitate the success of existing faculty in the constantly changing environment of academia. In response to concerns regarding the challenges wrought by current and projected shortages of dental faculty across the nation, the FDC was prompted to assess development opportunities available to BCD faculty. A professional development resource that we found deficient was a formal, comprehensive orientation program for newly hired faculty. To guide the efforts of the committee in developing this program, a survey was designed and administered during an annual faculty retreat. Respondents were new and junior faculty, senior faculty, and some administrators. The results of the survey to determine requirements for new faculty orientation became the basis for formalizing BCD's new faculty orientation program. This article provides an overview of the new faculty orientation process from design to program implementation and describes the development and use of a faculty survey to determine the fundamental elements of a faculty development program, identification of essential individuals for designing/implementing the program, and implementation of a new faculty orientation program at BCD.

SummaryOngoing political controversies around the world exemplify a long-standing and widespread preoccupation with the acceptability of homosexuality. Nonheterosexual people have seen dramatic surges both in their rights and in positive public opinion in many Western countries. In contrast, in much of Africa, the Middle East, the Caribbean, Oceania, and parts of Asia, homosexual behavior remains illegal and severely punishable, with some countries retaining the death penalty for it. Political controversies about sexual orientation have often overlapped with scientific controversies. That is, participants on both sides of the sociopolitical debates have tended to believe that scientific findings-and scientific truths-about sexual orientation matter a great deal in making political decisions. The most contentious scientific issues have concerned the causes of sexual orientation-that is, why are some people heterosexual, others bisexual, and others homosexual? The actual relevance of these issues to social, political, and ethical decisions is often poorly justified, however. © The Author(s) 2016.

Sexual orientation and spatial memory.

Cánovas, Ma Rosa; Cimadevilla, José Manuel

2011-11-01

The present study aimed at determining the influence of sexual orientation in human spatial learning and memory. Participants performed the Boxes Room, a virtual reality version of the Holeboard. In Experiment I, a reference memory task, the position of the hidden rewards remained constant during the whole experiment. In Experiment II, a working memory task, the position of rewards changed between blocks. Each block consisted of two trials: One trial for acquisition and another for retrieval. The results of Experiment I showed that heterosexual men performed better than homosexual men and heterosexual women. They found the rewarded boxes faster. Moreover, homosexual participants committed more errors than heterosexuals. Experiment II showed that working memory abilities are the same in groups of different sexual orientation. These results suggest that sexual orientation is related to spatial navigation abilities, but mostly in men, and limited to reference memory, which depends more on the function of the hippocampal system.

Updating of visual orientation in a gravity-based reference frame.

The brain can use multiple reference frames to code line orientation, including head-, object-, and gravity-centered references. If these frames change orientation, their representations must be updated to keep register with actual line orientation. We tested this internal updating during head rotation in roll, exploiting the rod-and-frame effect: The illusory tilt of a vertical line surrounded by a tilted visual frame. If line orientation is stored relative to gravity, these distortions should also affect the updating process. Alternatively, if coding is head- or frame-centered, updating errors should be related to the changes in their orientation. Ten subjects were instructed to memorize the orientation of a briefly flashed line, surrounded by a tilted visual frame, then rotate their head, and subsequently judge the orientation of a second line relative to the memorized first while the frame was upright. Results showed that updating errors were mostly related to the amount of subjective distortion of gravity at both the initial and final head orientation, rather than to the amount of intervening head rotation. In some subjects, a smaller part of the updating error was also related to the change of visual frame orientation. We conclude that the brain relies primarily on a gravity-based reference to remember line orientation during head roll.

Conservative orientation as a determinant of hopelessness.

Science.gov (United States)

Cheung, C K; Kwok, S T

1996-06-01

Conservative orientation is identified with reference to authoritarianism, work ethic belief, just world belief, and endorsement of individualistic causes of social problems. This over-arching orientation is hypothesized to affect hopelessness and to be affected by self-esteem with reference to ego development theory and learned helplessness theory. Causal modeling of data obtained from 1st-year college students (N = 556) in Hong Kong supports the hypotheses, showing that a student's hopelessness relates to his or her conservative orientation, even when self-esteem is controlled. This relationship can be interpreted by ego development and learned helplessness theories and cannot be explained as a spurious effect. Through the theories, hopelessness is interpreted as a result of maladaptive development and fatalistic, alienated, and helpless outlooks. This maladaptive development and the outlooks in turn result from students' conservative and individualistic orientation.

Full Text Available In article approaches to training of student in object-oriented programming in the environment of the Windows operating system are considered. The analysis of the literature on the programming and the modern school textbook on informatics, and also theoretical material on object-oriented programming within the informative line “Algorithmization and programming” of school course of informatics is for this purpose carried out. The object-oriented approached essentially differs from structured programming in fact that the object-oriented programming paradigm is more open and scalable. It doesn’t mean that transition to the object-oriented approach to programming demands a failure from all algorithm applied in case of structural pro-applications of all earlier found and tested method and receptions. On the contrary new elements are always based on prior experience. Object approach creates a set of essential convenience which under other conditions can’t provide. Object-oriented programming in the environment of the Windows operating system to interest student from the first lesson and to do training fascinating and interesting because student can control object which the modern students face since the childhood on the personal computers, pads and phones.

Orienting and Onboarding Clinical Nurse Specialists: A Process Improvement Project.

Science.gov (United States)

Garcia, Mayra G; Watt, Jennifer L; Falder-Saeed, Karie; Lewis, Brennan; Patton, Lindsey

Clinical nurse specialists (CNSs) have a unique advanced practice role. This article describes a process useful in establishing a comprehensive orientation and onboarding program for a newly hired CNS. The project team used the National Association of Clinical Nurse Specialists core competencies as a guide to construct a process for effectively onboarding and orienting newly hired CNSs. Standardized documents were created for the orientation process including a competency checklist, needs assessment template, and professional evaluation goals. In addition, other documents were revised to streamline the orientation process. Standardizing the onboarding and orientation process has demonstrated favorable results. As of 2016, 3 CNSs have successfully been oriented and onboarded using the new process. Unique healthcare roles require special focus when onboarding and orienting into a healthcare system. The use of the National Association of Clinical Nurse Specialists core competencies guided the project in establishing a successful orientation and onboarding process for newly hired CNSs.

2012-12-01

Full Text Available The article is devoted to the ethnic features of value orientations in students from different parts of the world. It is shown that the lives of the students from Latin America and Central Asia are more holistic and meaningful than the lives of the students from China, the Middle East and Russia. Latin American students are more focused on individuality, self-regulation, and the Central Asian — on collectivism, the controllability of life events. The gender specifics of the value orientations of students are described. The connection between the students’ value orientations personality components such as a basic trust in the world, social and emotional intelligence, ethnic identity and tolerance towards the people of other ethnic groups, stress-coping strategies are analyzed.

Full Text Available The study is aimed at investigating the dynamics of students’ value orientation at the pedagogic higher school. The subject of the research incorporates the value-motivation sphere as being the component of students’ cognitive interest. The research methodology is based on the system determinism principle and combines the theoretical and practical substantiation of the value orientation problem as the main component of students’ cognitive interest. The research results referred to the professional activity values, growing year after year during the undergraduate course, can be taken into account in developing the value–motivation sphere of the studentship. The research shows that the proper psychological conditions created in the educational environment make the develop- ment of the value orientation system more successful. 

Photochemical dynamics of surface oriented molecules

Ho, W.

1992-01-01

The period 8/01/91-7/31/92 is the first year of a new project titled ''Photochemical Dynamics of Surface Oriented Molecules'', initiated with DOE Support. The main objective of this project is to understand the dynamics of elementary chemical reactions by studying photochemical dynamics of surface-oriented molecules. In addition, the mechanisms of photon-surface interactions need to be elucidated. The strategy is to carry out experiments to measure the translational energy distribution, as a function of the angle from the surface normal, of the photoproducts by time-of-flight (TOF) technique by varying the photon wavelength, intensity, polarization, and pulse duration. By choosing adsorbates with different bonding configuration, the effects of adsorbate orientation on surface photochemical dynamics can be studied
