The Northern Patagonia Icefield (NPI) is the primary glaciated terrain worldwide at its latitude (46.5–47.5°S), and constraining its glacial history provides unique information for reconstructing Southern Hemisphere paleoclimate. The Colonia Glacier is the largest outlet glacier draining the eastern NPI. Ages were determined using dendrochronology, lichenometry, radiocarbon, cosmogenic 10Be and optically stimulated luminescence. Dated moraines in the Colonia valley defined advances at 13.2 ± 0.95, 11.0 ± 0.47 and 4.96 ± 0.21 ka, with the last being the first constraint on the onset of Neoglaciation for the eastern NPI from a directly dated landform. Dating in the tributary Cachet valley, which contains an ice-dammed lake during periods of Colonia Glacier expansion, defined an advance at ca. 2.95 ± 0.21 ka, periods of advancement at 810 ± 49 cal a BP and 245 ± 13 cal a BP, and retreat during the intervening periods. Recent Colonia Glacier thinning, which began in the late 1800s, opened a lower-elevation outlet channel for Lago Cachet Dos in ca. 1960. Our data provide the most comprehensive set of Latest Pleistocene and Holocene ages for a single NPI outlet glacier and expand previously developed NPI glacial chronologies.

Full Text Available The issues of Colonia Lepida allow us to propose the years 48-87 B.C. as its foundation date. The city, previously known by the Iberian name of Celsa, was changed to Lepida probably as a punishment for its support to the Pompeyan party. On 36 B.C. the colony regains its name Celsa. In 19 B.C. Agrippa stablishes here as imperial mint for aurei and denarii that had previously been adscribed to Caesarugusta, even though this city was then not yet founded. Judging by the circulation coinage and by the heavy metrology which lasts until Augustan times. Lepida seems to have coined bronze for military needs since Pompeyan issues.Las emisiones de Colonia Lepida permiten proponer el año 48-87 a.C. como la fecha de fundación de la colonia e interpretar la abolición del nombre de la ciudad ibérica Celsa como un castigo por su adhesión al bando pompeyano. En el 36 la ciudad recupera su nombre Celsa. En el 19 a.C. Agripa debe establecer en la colonia una ceca imperial que habíamos adscrito a Caesaraugusta, ciudad que todavía no estaba fundada, y provocar con ello una gran eclosión urbanística y política de Colonia Celsa. A juzgar por la circulación monetaria y la metrología uncial que se mantendrá hasta tiempos de Augusto, la ciudad parece, ya desde sus emisiones bilingües pompeyanas, haber abastecido de numerario de bronce a las tropas.

Assessment of a constructed wetland for water recovery and beneficial use of shredded tires in a colonia

'Full text:' Currently, in many areas of the nation, small communities exist without access to adequate and safe water supplies. Texas, New Mexico, Arizona, and California have several of these communities, called colonias, along the border with Mexico. Many of these communities suffer from high rates of infectious disease due to contaminated sources, unacceptable available water quality, insufficient water quantity, and/or undeveloped infrastructure. Solving these types of problems will require a design born of careful integration of cultural, technical, and regulatory considerations. This project proposes to utilize constructed wetland design as a viable economic solution for a colonia situation that can serve as a test case for more widespread use of this technology. The design will merge technical, social and regulatory aspects of water recycling into one approach. Detailed requirements of the design will include scientific, engineering, and cultural aspects of the system. Based on the social, economic, technical, and environmental information gathered, select up to two on-site water recovery system technologies that are simple, inexpensive, and culturally acceptable. Details of design (plants selected, effluent discharge) are based on interviews with colonia residents to determine their needs. Final site selection is based on poor soils (inappropriate for a leach field), vicinity to schools, and interested families. A comparison of options determined a constructed wetland to be the most viable option. Chipped tires are used as the media, hence, a solid waste problem (local resource) in colonias is converted to a beneficial use. We then analyze and monitor the field performance of the constructed wetland paying special attention to the early TSS discharge of rust particles from steel belted tires. Students are involved from colonia communities in monitoring of systems and environmental data collection. The lessons learned to date are given and construction will

The increasing numbers of colonias along the U.S.-Mexico border are characterized by disproportionately poor families of Mexican-origin, limited access to resources and health services, and heightened risk for obesity and diabetes. Despite consistent evidence supporting physical activity (PA) in prevention of chronic diseases, many individuals of Mexican-origin, including children, fail to meet PA recommendations. Environmental influences on PA, founded in ecological and social cognitive perspectives, have not been examined among children living in colonias. The purpose of this study was to identify and better understand (1) household and neighborhood environmental PA resources/supports, (2) perceived barriers to engaging in PA, and (3) PA offerings, locations, and transportation characteristics for Mexican-origin children living in colonias. Data for this study were collected by promotora-researchers (indigenous community health workers trained in research methods) using face-to-face interviews conducted in Spanish. The sample consists of 94 mother-child dyads from Texas border colonias in Hidalgo County. Interviews included questionnaire items addressing PA barriers, household and neighborhood environmental support assessments conducted with each dyad, and open-ended questions that were coded to identify availability and locations of PA opportunities and transportation options. Descriptive statistics were calculated and differences between genders, birth countries, and BMI categories of children were determined using chi-square tests. All children were of Mexican-origin. The most frequently reported barriers were unleashed dogs in the street, heat, bad weather, traffic, no streetlights, and no place like a park to exercise. Prominent locations for current PA included schools, home, and parks. Common PA options for children were exercise equipment, running, playing, and sports. Environmental assessments identified exercise equipment (bicycles/tricycles, balls, etc

The qualitative study described in this article investigated perceptions about environmental factors influencing physical activity (PA) among children from underserved neighborhoods known as colonias in the U.S.-Mexico border. Ten focus groups were conducted with 67 Mexican-American colonia children ages 8 to 13 living in one of the poorest border counties in the U.S. Analyses indicated that PA among children was influenced by neighborhood characteristics, including litter, speeding cars, unleashed dogs, and dark streets. The children also underlined intrapersonal and social environmental factors. Findings may inform policy makers and public health professionals about ways to promote PA among underserved children through urban planning and programs focusing on PA-supportive infrastructure, neighborhood safety, and family- and home-based physical activities.

This study examines urban pollution within Derechos Humanos, a colonia popular in Matamoros, Tamaulipas, Mexico. General water quality indicators (coliform bacteria, total dissolved solids, ecologically relevant cations and anions), heavy metals (copper, lead, nickel, zinc, iron and cadmium), and volatile organic compounds (benzene, toluene, ethylbenzene, styrene, and dichlorobenzene and xylene isomers) were quantified within a wastewater canal running adjacent to the community. Water samples were collected at multiple sites along the banks of the canal and evidence of anthropogenic emissions existed at each sampling location. Sample site 2, approximately 10 m upstream of the colonia, contained both the widest range of hazardous pollutants and the greatest number exceeding US Environmental Protection Agency surface water standards. At each sampling location, high concentrations of total coliform (> 10(4) colonies/100 mL sample), lead (ranging from 0.05 to 0.40 mg/L), nickel (levels from 0.21 to 1.45 mg/L), and benzene (up to 9.80 mg/L) were noted.

Full Text Available The paper analyzes the agri-food trade of Moldova from different aspects of intra-industry trade. The aim is to estimate the trend and extent of intra-industry trade in agri-food products of Moldova. The time series from 2001-2015 are examined. According to the obtained results, the level of intra-industry trade in agricultural and food products for Moldova is quite high (78%, fact which indicates a decline of trade relationships with EU countries and an increase with CIS countries. For most commodity groups the values of Grubel Lloyd index present a high average variability over time, fact which reflects the structural changes in Moldova’s agri-food trade. The values of A indices are very low and indicate that most of changes in trade flows had been inter-industrial in nature and probably generated high adjustment costs. The switching results of the B index of marginal intra-industry trade indicate that Moldova’s position on these markets considerably improved and strengthened. Rezumat.

Texas colonias are unincorporated subdivisions characterized by inadequate water and wastewater infrastructure, inadequate drainage and road infrastructure, substandard housing, and poverty. Since 1989 the Texas Legislature has implemented policies to halt further development of colonias and to address water and wastewater infrastructure needs in existing and new colonias along the border with Mexico. Government programs and non-government and private organization projects aim to address these infrastructure needs. Texas Tech University's Water Resources Center demonstrated the use of alternative on-site wastewater treatment in the Green Valley Farms colonia, San Benito, Texas. The work in Green Valley Farms was a component of a NASA-funded project entitled Evaluation of NASA's Advanced Life Support Integrated Water Recovery System for Non-Optimal Conditions and Terrestrial Applications. Two households within the colonia are demonstration sites for constructed wetlands. A colonia resident and activist identified educational opportunities for colonia children as a primary goal for many colonia residents. Colonia parents view education as the door to opportunity and escape from poverty for their children. The educational outreach component of the project in Green Valley Farms was a Science and Space Club for middle-school age students. Involved parents, schoolteachers, and school administrators enthusiastically supported the monthly club meetings and activities. Each month, students participated in interactive learning experiences about water use and reuse in space and on earth. Activities increased knowledge and interest in water resource issues and in science and engineering fields. The Institute for the Development and Enrichment of Advanced Learners (IDEAL) at Texas Tech University provided full scholarships for five students from Green Valley Farms to attend the Shake Hands With Your Future camp at Texas Tech University in June 2003.

Full Text Available Myotis emarginatus (Chiroptera, Vespertilionidae utilizza frequentemente gli edifici come rifugio estivo, sia per il riposo diurno che per la riproduzione. Negli anni 1996-2003, nel corso di indagini faunistiche sul territorio toscano, questa specie è stata rilevata nel 26% dei casi su 76 edifici rurali risultati occupati da pipistrelli e rappresenta ben il 50% degli esemplari rilevati. Il numero di esemplari di M. emarginatus in tali rifugi varia da 1 a 150 animali. Un edificio però può rendersi facilmente indisponibile per modificazioni nell?utilizzo da parte dell?uomo: ma cosa succede agli animali che si trovano improvvisamente senza casa? E quanto si può accrescere annualmente una colonia quando non viene disturbata? Nel 1997 nella Riserva Naturale Provinciale di Ponte a Buriano e Penna (AR, rilevammo una colonia riproduttiva di Myotis emarginatus stimata in circa 60 esemplari. Il rifugio estivo utilizzato fino al 2002 è costituito da una casa disabitata. Confrontando le stime effettuate dal 1997 al 2001 possiamo valutare l?accrescimento numerico della colonia: a partire dai circa 60 animali si è raggiunta la consistenza di 75 esemplari nel 2001, ossia circa il 25% in 5 anni (5% annuo di media. I conteggi sono stati effettuati a vista da almeno 3 persone, da breve distanza e in buona luce, ma poiché in questa specie gli esemplari si appendono alle travi addossandosi uno sopra l?altro, è impossibile effettuare un vero conteggio. Nell?estate 2001 abbiamo condotto una ricerca più accurata sull?utilizzo del rifugio: dai rilievi di un rilevatore di passaggio all?infrarosso e soprattutto dalle riprese di una videocamera, risulta che il numero degli esemplari era stato fortemente sottostimato: gli esemplari erano, infatti, ben 150 (femmine, ossia il doppio di quanto stimato sia pure in condizioni favorevoli. A Giugno (2001 abbiamo registrato la nascita di 101 piccoli, il cui tasso di mortalità prima dell

En este artículo estimamos una serie de modelos para analizar el grado de satisfacción con la colonia de una muestra de hogares en el estado de Zacatecas. Las estimaciones nos permiten determinar si el programa federal de vivienda Tu Casa en ese estado, operado de 2004 a 2009, tuvo alguna influencia en el grado de satisfacción con la colonia, de acuerdo con la percepción de los residentes entrevistados. Encontramos evidencia de que el referido programa causó un efecto significativo en el grado de satisfacción del grupo de familias beneficiarias. Además de ese resultado, la estimación por mínimos cuadrados ordinarios muestra que el acceso vial, la contaminación ambiental, la percepción del valor de la casa y el tiempo de vivir en la vivienda influyen de forma significativa en el grado de satisfacción con la colonia. En los modelos estimados por probit y logit encontramos evidencia de que la seguridad pública y la posesión del inmueble también influyen en tal satisfacción.

The U.S. Department of Housing and Urban Development (HUD) and the U.S. Geological Survey (USGS) have developed a joint project to create Internet-enabled geographic information systems (GIS) that will help cities along the United States-Mexico border deal with issues related to colonias. HUD defines colonias as rural neighborhoods in the United States-Mexico border region that lack adequate infrastructure or housing and other basic services. They typically have high poverty rates that make it difficult for residents to pay for roads, sanitary water and sewer systems, decent housing, street lighting, and other services through assessment. Many Federal agencies recognize colonias designations and provide funding assistance. It is the intention of this project to empower Arizona-Sonora borderland neighborhoods and community members by recognizing them as colonias. This recognition will result in eligibility for available economic subsidies and accessibility to geospatial tools and information for urban planning. The steps to achieve this goal include delineation of colonia-like neighborhoods, identification of their urbanization over time, development of geospatial databases describing their infrastructure, and establishment of a framework for distributing Web-based GIS decision support systems. A combination of imagery and infrastructure information was used to help delineate colonia boundaries. A land-use change analysis, focused on urbanization in the cities over a 30-year timeframe, was implemented. The results of this project are being served over the Internet, providing data to the public as well as to participating agencies. One of the initial study areas for this project was the City of Douglas, Ariz., and its Mexican sister-city Agua Prieta, Sonora, which are described herein. Because of its location on the border, this twin-cities area is especially well suited to international manufacturing and commerce, which has, in turn, led to an uncontrolled spread of

Full Text Available La diferenciación rápida de colonias bacterianas es esencial en muchos campos industriales, científicos y de salud humana y animal. Generalmente esa diferenciación se logra por técnicas microscópicas, bioquímicas o genéticas muy elaboradas que requieren tiempo y entrenamiento. En este estudio se utilizaron técnicas de análisis de imágenes sobre patrones de difracción de luz láser para evaluar su sensibilidad en la diferenciación de colonias bacterianas. Adicionalmente se estudió el efecto del tiempo de crecimiento de las colonias en la generación de estos patrones y se determinó la influencia de la cantidad de medio de cultivo en la difracción de luz láser. Los patrones de difracción del láser se obtuvieron sobre cultivos puros de cinco aislamientos bacterianos B1, B2, B3, B2Ca y B2Cb. En la primera prueba de diferenciación se utilizaron colonias de B2, B3, B2Ca. En el estudio del efecto del tiempo de crecimiento sobre patrones de difracción, las bacterias B1 y B2Cb con uno o dos días de crecimiento. Finalmente, el efecto de la cantidad de medio de cultivo en la difracción de la luz, se evaluó en una prueba en cajas petri con 10, 15 o 20 ml de medio de cultivo estéril sin colonias de bacterias. Mediante un análisis de escalado multidimensional realizado con los parámetros de textura extraídos de las imágenes de los patrones, se obtuvo un agrupamiento adecuado de los patrones asociados a las colonias de cada bacteria evaluada, lo cual indicó que las colonias bacterianas se pueden diferenciar por sus patrones de difracción. Adicionalmente se encontró que no hay variaciones significativas en los patrones de difracción obtenidos de dos aislamientos bacterianos en dos tiempos de crecimiento. El espesor del medio de cultivo afectó la difracción del haz de luz pues patrones obtenidos de cajas petri con 10 ml se separan completamente de los patrones obtenidos con 15 y 20 ml, aunque no hay diferencias entre los dos

In order to study the groundwater dynamics of the Northwest of the Entre Rios Province (Republica Argentina), supported on the regional knowledge resulting from previous reports, a detailed investigation is developed. The most important aquifer of the region, conformed by sands of the Ituzaingo and Parana Formations (Mioceno-Plioceno) underlies Hernandarias Formation (Pleistoceno) thick clays cover. This confinement condition, and the complex hydrodynamic behaviour as a result of the heterogeneity of the hydrogeological sequence, impeded determine with clearness the existence of actual and direct connections with the exterior cycle. The application of classical geohydrochemical methodologies complemented with both isotopic and heavy metals measurements, and data geostatistical processing, allows to formulate hypothesis about groundwater origin and the incidence of the autochthonous recharge.

Acta Geologica Polonica, 63 (2), 175-199. Warszawa. The continental, coal bearing Steierdorf Formation, Hettangian - Sinemurian in age, is included in the Mesozoic cover of the Reşiţa Basin, Getic Nappe, South Carpathians, Romania. The Steierdorf Formation can be studied in Anina, a coal mining center and an exceptional locality for Early Jurassic flora and fauna, occurring in the middle of the Reşiţa Basin. This paper presents the results of sedimentological, stratigraphical and paleobotanical researches undertaken in Colonia Cehă open cast mine in Anina, where the Steierdorf Formation outcrops widely. Several sedimentary facies associations have been described, these associations permitting the reconstruction of various depositional systems such as alluvial fans, braided and meandering river systems, as well as lacustrine and coal generating marsh systems of the Steierdorf Formation. The sedimentary associations recorded within the Steierdorf Formation show a gradual fining upward trend, pointing to a rising marine water table and a decreasing relief within the source area.

This report outlines a planning approach taken by a Federal Government partnership that is meant to promote sustainable development in the future, integrating both sides of the United States-Mexican border. The twin-city area of Nogales, Ariz., and Nogales, Sonora, Mexico, known collectively as Ambos (both) Nogales, has a common borderland history of urban growth presumably based on changes in policy and economic incentives. We document changes over time in an attempt to identify colonia development and settlement patterns along the border, combining a community-participation approach with a remote-sensing analysis, to create an online mapping service.

Se utilizaron 32 colonias que variaban en sus niveles de infestación del ácaro y que no habían recibido ningún acaricida durante dos años. Se determinó la producción de miel y el nivel de parasitosis en abejas adultas de estas colonias y los datos se sometieron a un análisis de correlación. Se encontró una correlación negativa y significativa entre el nivel de infestación por Varroa y la producción de miel (r= -0.44, P=0.01. Los valores medios de infestación y producción de miel (±DE fueron 15.21 ± 8.44 % y 36.26 ± 29.24 kg, respectivamente. Los resultados indican que al incrementarse el nivel de varroosis, la producción de miel se reduce de manera significativa. Se recomienda que las colonias de abejas infestadas por Varroa destructor sean sometidas a métodos de control que reduzcan la población del ácaro para contribuir a incrementar la producción de miel.

Full Text Available El queso Colonia es un queso típico uruguayo, elaborado según los criterios de calidad y tradición quesera de los inmigrantes suizos radicados en la cuenca lechera del departamento de Colonia. En la actualidad no se reporta información publicada acerca de los cambios reológicos que ocurren en el queso durante su maduración. Su investigación y publicación aportan conocimiento para la difusión de un proceso que aún no presenta denominación de origen protegida. En el presente trabajo se midieron los cambios reológicos mediante el ensayo de relajación-compresión, durante el proceso de maduración realizado a 8 ºC y 85 % de humedad relativa hasta el día 13. Los resultados obtenidos manifiestan la existencia de un cambio importante del comportamiento a partir del día 11 de maduración, momento en que ocurre un notorio ablandamiento del queso. Esto concuerda con la práctica industrial que tradicionalmente realiza el cambio de los quesos para continuar su maduración en cámara caliente a partir del onceavo día. Este estudio demuestra la importancia de esperar hasta el onceavo día para asegurar la elasticidad necesaria en el queso para una adecuada formación de ojos en la cámara caliente.Abstract“Colonia” cheese is a typical Uruguayan cheese, elaborated following the quality standards and cheese making tradition of the swiss inmigrants established at the uruguayan department of Colonia and sourrondings.

Full Text Available El tamaño de la colonia es un atributo fundamental de la biología de las hormigas ya que está asociado a características ecológicamente relevantes, como sus estrategias de alimentación. Mientras que el tamaño de la colonia de varias especies de hormigas granívoras del género Pogonomyrmex de América del Norte se ha estudiado en detalle, no existe tal información para las especies de América del Sur. En este trabajo, se determinó el tamaño y la composición de la colonia y se describió la estructura del nido de tres especies de Pogonomyrmex que habitan la porción central del desierto del Monte en Argentina: P. mendozanus Cuezzo & Claver, P. inermis Forel y P. rastratus Mayr. Para ello, se excavaron dos nidos de cada especie y se recolectaron todos los individuos encontrados. Las tres especies tienen colonias pequeñas, compuestas por 300-1.100 individuos, de los cuales aproximadamente el 70% son obreras adultas. La estructura de sus nidos es relativamente simple, similar a la de la mayoría de las especies norteamericanas estudiadas, pero con un menor desarrollo en profundidad y un número menor de cámaras; probablemente se deba al menor número de obreras que poseen. Estas características (colonias pequeñas y nidos poco desarrollados son consideradas típicas para las especies del género Pogonomyrmex de América del Sur, lo que las diferencia de la mayoría de sus congéneres estudiados en América del Norte.

Nutritional health is essential for children's growth and development. Many Mexican-origin children who reside in limited-resource colonias along the Texas-Mexico border are at increased risk for poor nutrition as a result of household food insecurity. However, little is known about the prevalence of child hunger or its associated factors among children of Mexican immigrants. This study determines the prevalence of child hunger and identifies protective and risk factors associated with it in two Texas border areas. This study uses 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA) data from 470 mothers who were randomly recruited by promotora-researchers. Participants from colonias near two small towns in two South Texas counties participated in an in-home community and household assessment. Interviewer-administered surveys collected data in Spanish on sociodemographics, federal food assistance program participation, and food security status. Frequencies and bivariate correlations were examined while a random-effects logistic regression model with backward elimination was used to determine correlates of childhood hunger. Hunger among children was reported in 51% (n = 239) of households in this C-HCFRA sample. Bivariate analyses revealed that hunger status was associated with select maternal characteristics, such as lower educational attainment and Mexican nativity, and household characteristics, including household composition, reliance on friend or neighbor for transportation, food purchase at dollar stores and from neighbors, and participation in school-based nutrition programs. A smaller percentage of households with child hunger participated in school-based nutrition programs (51%) or used alternative food sources, while 131 households were unable to give their child or children a balanced meal during the school year and 145 households during summer months. In the random effects model (RE = small town), increased household

Methods The study used data from the 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA. The data included 610 face-to-face interviews conducted in Spanish by promotoras (indigenous community health workers in forty-four randomly-identified colonias near the towns of Progreso and La Feria in Hidalgo and Cameron counties along the Texas border with Mexico. C-HCFRA included demographic characteristics, health characteristics, food access and mobility, food cost, federal and community food and nutrition assistance programs, perceived quality of the food environment, food security, eating behaviors, and alternative food sources. Results 78% of participants experienced food insecurity at the level of household, adult, or child. The most severe - child food insecurity was reported by 49% of all households and 61.8% of households with children. Increasing levels of food insecurity was associated with being born in Mexico, increasing household composition, decreasing household income, and employment. Participation in federal food assistance programs was associated with reduced severity of food insecurity.

This study describes the perceptions of brain health among older Spanish-speaking Mexican Americans who reside in colonia areas of the Lower Rio Grande Valley of Texas. In 2007, 33 Mexican American older adults (9 men and 24 women) were recruited by promotoras (community health workers) from clusters of colonias in Hidalgo County to participate in focus group discussions conducted in Spanish. After participants completed a 19-item questionnaire (in Spanish), a bilingual and bicultural researcher from the community, trained as a moderator, conducted 4 focus groups using a semistructured interview guide, culturally modified with the assistance of promotoras. All discussions were audio recorded; audio recordings were transcribed verbatim in Spanish and then translated into English. Analyses were conducted in English. Almost 85% had less than a high school education and 100% reported a household income less than $20,000/year. Groups attached cultural meaning to aging well. The idea of "staying straight in the mind" resonated as a depiction of brain health. Participants also mentioned the types of activities they could do to stay "right in the mind." Particular attention must be focused on development of programs that provide satisfying culturally appropriate activities for older participants and the delivery of health messages that take into consideration culture and language.

Full Text Available Lo que se plantea en el presente texto es que Sarita Colonia, culto de origen popular migrante andino peruano, ha sufrido una notoria transformación que se dirige hacia la constitución de un ícono de lo popular emergente integrado, debido a la contribución de algunos medios de comunicación, intelectuales y artistas, que son espacios de producción de significación de origen no popular. Sarita y lo que su culto religioso representa, han sido “domesticados” e idealizados por parte de estos espacios de producción de significación para asirse de algún referente de lo popular como integrado. De este modo han logrado constituir a Sarita como algo más que un culto religioso: un ícono o referente comunicativo de un ideal de lo popular; semántica, gramática, medio de comunicación, que conativamente comunica lo popular con lo burgués, para generar diálogo entre este y aquel. Sarita Colonia es la lingua franca que permite empatía entre lo popular y lo pequeño-burgués ilustrado con afán de utopizar la sociedad, de manera que ella ha llegado a formar parte del espacio público de significaciones sociales, dentro de un flujo de íconos que objetivan las esperanzas y logros de los pobres, así como los mensajes de alianza e integración de parte de los burgueses de cierta vanguardia cultural, en Lima, Perú.

Las cofradías cumplieron en la Colonia y hasta la primera mitad del siglo XIX un papel no sólo religioso sino también económico al poseer tierras y actuar como entidades financieras. Las personas ligadas a las operaciones económicas de las cofradías eran los miembros de la élite local, quienes formaban una red social. Junto al capital manejado por la Iglesia y sus instituciones (cofradías, y diversos tipos de fundaciones como las capellanías y los mayorazgos) a lo largo de la Colonia se produ...

Micro-Grids for Colonias (TX)

This report describes the results of the final implementation and testing of a hybrid micro-grid system designed for off-grid applications in underserved Colonias along the Texas/Mexico border. The project is a federally funded follow-on to a project funded by the Texas State Energy Conservation Office in 2007 that developed and demonstrated initial prototype hybrid generation systems consisting of a proprietary energy storage technology, high efficiency charging and inverting systems, photovoltaic cells, a wind turbine, and bio-diesel generators. This combination of technologies provided continuous power to dwellings that are not grid connected, with a significant savings in fuel by allowing power generation at highly efficient operating conditions. The objective of this project was to complete development of the prototype systems and to finalize and engineering design; to install and operate the systems in the intended environment, and to evaluate the technical and economic effectiveness of the systems. The objectives of this project were met. This report documents the final design that was achieved and includes the engineering design documents for the system. The system operated as designed, with the system availability limited by maintenance requirements of the diesel gensets. Overall, the system achieved a 96% availability over the operation of the three deployed systems. Capital costs of the systems were dependent upon both the size of the generation system and the scope of the distribution grid, but, in this instance, the systems averaged $0.72/kWh delivered. This cost would decrease significantly as utilization of the system increased. The system with the highest utilization achieved a capitol cost amortized value of $0.34/kWh produced. The average amortized fuel and maintenance cost was $0.48/kWh which was dependent upon the amount of maintenance required by the diesel generator. Economically, the system is difficult to justify as an alternative to grid

Full Text Available Abstract Background Trends of increasing obesity are especially pronounced among Mexican-origin women. There is little understanding of dietary patterns among U.S.- and Mexico-born Mexican-origin individuals residing in new-destination immigrant communities in the United States, especially behaviors related to obesity, such as consumption of sugar-sweetened beverages (SSB and fast-food meals (FFM. Methods The study used survey data of 599 adult Mexican-origin women from the 610 women who completed the 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA, which was completed in person by trained promotora-researchers in 44 colonias near the Texas border towns of Progreso and La Feria. Data included demographic characteristics (age, education, nativity or country of birth, household income, household composition, and employment status, access to transportation, self-reported height and weight, food and nutrition assistance program participation, and consumption of SSB and FFM. Descriptive statistics were calculated by nativity (U.S.-born vs. Mexico-born; multivariable linear regression models were estimated for correlates of consumption of SSB and FFM. Results There are three major findings related to nativity. First, U.S.-born women consumed more SSB and FFM than Mexican-born counterparts in the same areas of colonias. Second, in the combined sample and controlling for other population characteristics, being born in Mexico was independently associated with FFM (fewer FFM, but not with SSB. Third, in analyses stratified by nativity, FFM and SSB were associated with each other among both nativity groups. Among Mexico-born women only, age, presence of a child, or being a lone parent was significantly associated with SSB; full-time employment, being a lone parent, and SSB consumption were each independently associated with increased frequency of FFM. Conclusions Our analyses revealed differences in prevalence and correlates of SSB

Few studies have focused on the relationship between the retail food environment and household food supplies. This study examines spatial access to retail food stores, food shopping habits, and nutrients available in household food supplies among 50 Mexican-origin families residing in Texas border colonias. The design was cross-sectional; data were collected in the home March to June 2010 by promotora-researchers. Ground-truthed methods enumerated traditional (supercenters, supermarkets, grocery stores), convenience (convenience stores and food marts), and non-traditional (dollar stores, discount stores) retail food stores. Spatial access was computed using the network distance from each participant's residence to each food store. Data included survey data and two household food inventories (HFI) of the presence and amount of food items in the home. The Spanish language interviewer-administered survey included demographics, transportation access, food purchasing, food and nutrition assistance program participation, and the 18-item Core Food Security Module. Nutrition Data Systems for Research (NDS-R) was used to calculate HFI nutrients. Adult equivalent adjustment constants (AE), based on age and gender calorie needs, were calculated based on the age- and gender composition of each household and used to adjust HFI nutrients for household composition. Data were analyzed using bivariate analysis and linear regression models to determine the association of independent variables with the availability of each AE-adjusted nutrient. Regression models showed that households in which the child independently purchased food from a convenience store at least once a week had foods and beverages with increased amounts of total energy, total fat, and saturated fat. A greater distance to the nearest convenience store was associated with reduced amounts of total energy, vitamin D, total sugar, added sugar, total fat, and saturated fat.

parte de la estrategia de la CFE para incrementar la generacion de energia electrica mediante fuentes no convencionales llevo a cabo un calculo del potencial geotermico del pais. Este calculo se efectuo a traves del inventario nacional de manifestaciones termales con que cuenta la GPG, el cual ha permitido identificar 1380 manifestaciones termales distribuidas en todo el pais, con informacion de las temperaturas tomadas superficialmente y las temperaturas obtenidas por medio de geotermometros. El calculo del potencial geotermico se hizo con base en la clasificacion de estas manifestaciones por rangos de temperatura geotermometrica, obteniendose asi recursos de alta, media y baja entalpia. Posteriormente se utilizo el metodo volumetrico para obtener el potencial geotermico nacional. Los resultados indican que para las Reservas Posibles los recursos de alta entalpia ascienden a 5691 MWe, para los de moderada entalpia son de 881 MWe y los de baja entalpia de 849 MWe dando un total de 7422 MWe. Por otra parte, las Reservas Probables para el recurso de alta entalpia son de 1643 MWe, para los de moderada entalpia de 220 MWe y para los de baja entalpia de 212 MWe dando un total de 2077 MWe. Por ultimo las Reservas Probadas se tomaron como la capacidad adicional que puede instalarse en cada uno de los campos geotermicos conocidos, dando un total de 186 MWe. La informacion se proceso y se integro por medio del Sistema de Informacion Geografica (SIG) ArcGis 9.2 (c), dando como resultado la publicacion via Intranet del Mapa del Potencial Geotermico de la Republica Mexicana.

Full Text Available En este artículo se presenta un análisis de la actividad de los tamberos productores de leche que también elaboran quesos, en la Colonia San Martín, Departamento Paraná, Cuenca Lechera Oeste de la Provincia de Entre Ríos (Argentina. Se estudiaron seis casos identificando las formas de trabajo, la capacitación, las trayectorias de vidas, las normas de calidad en la elaboración de quesos y los circuitos de comercialización. Se utilizaron fuentes de información secundarias obtenidas del INTA y del Censo Nacional Agropecuario 2002, y se realizaron entrevistas semiestructuradas para lograr un mayor contacto con los informantes. Los resultados muestran que los establecimientos tambo- queseros son una fuente de empleo generador de valor agregado en la economía regional y van adaptando normas de calidad para competir en el mercado, favorecidos por el acceso a la energía eléctrica; la comercialización de sus productos se realiza dentro del mercado doméstico, a nivel local y regional.

El papel económico de las cofradías en el crepúsculo de la colonia y el ascenso de las sociedades mercantiles. Análisis de protocolos coloniales de San José (1837-1842

Full Text Available Las cofradías cumplieron en la Colonia y hasta la primera mitad del siglo XIX un papel no sólo religioso sino también económico al poseer tierras y actuar como entidades financieras. Las personas ligadas a las operaciones económicas de las cofradías eran los miembros de la élite local, quienes formaban una red social. Junto al capital manejado por la Iglesia y sus instituciones (cofradías, y diversos tipos de fundaciones como las capellanías y los mayorazgos a lo largo de la Colonia se produjeron alianzas (sociedades entre particulares, españoles peninsulares y criollos, para llevar a cabo inversiones y emprendimientos, como la exploración en busca de minas de oro y más tardíamente para operaciones de comercio exterior. El siglo XIX presenció el auge del pensamiento liberal y se produjo una desintegración paulatina de los bienes inmovilizados por la Iglesia y sus instituciones, lo que repercutió en la importancia de estas como agentes económicos. Ello también tuvo consecuencias en la propiedad de la tierra y en la legislación civil y comercial, que siguió al movimiento codificador iniciado en 1841 y se consagró en 1888, cuando entró a regir el Código Civil.

La investigación se realizó entre enero y junio de 2009, en seis localidades ubicadas entre 12m y 17m de profundidad. Como unidad de muestreo se empleó un marco de 1m², el cual fue puesto en zigzag cada 2m sobre la superficie del arrecife de macizos. Se determinó, por localidad, la densidad de colonias y se infirieron los grados de severidad, constancia ambiental, tensión hidrodinámica y el Índice Comparativo de Contaminación. Se determinaron, además, los daños en la comunidad de octocorales. Se analizaron 752 colonias e identificaron 25 especies de octocorales. Eunicea flexuosa y Gorgonia ventalina fueron las especies más abundantes. La densidad fluctuó entre 3.58±1.84 colonias/m² y 7.58±2.16 colonias/ m² (densidad de baja a moderada tendiendo a baja. En la zona se infirió una tensión hidrodinámica entre baja y alta, con niveles de contaminación bajos y moderados, y un ambiente generalmente favorable y constante. Los daños de tipo mecánico fueron los más frecuentes, siendo G. ventalina la especie con más colonias dañadas. La comunidad de octocorales del hábitat de macizos y canales de la Reserva Ecológica Siboney-Juticí presentó un buen estado de conservación.

Al respecto se resaltan dos cosas: el debate intelectual en torno a las distintas legislaciones (la colonial y la liberal y las razones y necesidades de organización social del modelo político prevaleciente.

Full Text Available The restoration of the interior of Colonia Güell Church, begun in October 2002, is only just the start. The lack of upkeep over the past years has produced numerous problems. Some are due lo lack of attention or the passing of lime. Others are the result of Gaudí not being able to finish the work he had created, and that nobody else stepped in lo complete what was left unfinished; even though it was essential to defining his work (as can be seen in the imperfect finishing touches in the construction work, which distorts the architect´s design. Other problems stem from the unfortunate consequences of those who had lo take over when Gaudí left and salve essential problems (such as the enormous draught proof doors and the low walls round the space meant for the spiral stairway lo the upper floor and the belfry, or the presbytery with its obvious lack of formal and liturgical characteristics.

De los muchos problemas por resolver -reflejo del estado de provisionalidad que ha caracterizado al conjunto durante años-, algunos son fruto de la falta de atención al deterioro o al paso del tiempo; otros son consecuencia de no haber podido acabar Gaudí la obra por él concebida: de no haber hecho nadie lo que no pudo hacer Gaudí, aun siendo esencial para definir su obra (como ocurre con los acabados constructivos no resueltos, que desnaturalizan la obra del arquitecto, o bien de los desaciertos de quienes se vieron obligados a dar respuestas imprescindibles tras su marcha (destacan, entre estos, el

Ambos fueron inmigrantes del último periodo borbónico y sus vidas se cruzaron en el Potosí bajo colonial al incorporarse en la misma red de paisanaje, a partir de donde ingresarán a la misma familia por matrimonio. En este contexto, las redes y los vínculos trazados previamente fueron los que permitieron la subsistencia y reproducción de las empresas ya existentes. Se analizan vínculos mercantiles, de paisanaje, familiares y diferentes estrategias comerciales que involucraban al espacio andino y que revelan las distintas opciones que los flujos mercantiles ofrecían al sector empresarial.This paper studies the lifetime of two businessmen from Jujuy during the period between the Colony and the early Independence: Manuel de Tezanos Pinto andjosep de Alvarado. They both became immigrants in the last Borbon period and met in the late colonial Potosi when joining the same native-net; eventually, they share by marriage. In this context, it was the nets and bonds -traced previously- the ones that allowed the subsistence and reproduction of the companies already in existence. Mercantile, native-net and family bonds are analyzed along with the different commercial strategies which used to involve the Andean space and that reveal the different options that the mercantile flows offered to the business sector.

Full Text Available Unul dintre conflictele motivaţionale întâlnite frecvent în mediul organizaţional este „conflictul familie-muncă”. Conflictul, în acest caz, derivă din nevoia de a integra în mod optim solicitările legate de rolul familial cu cele ale rolului profesional. Studiile relevă că acest tip de conflict este o sursă considerabilă de distres atât pentru angajaţi, cât şi pentru organizaţie, afectează starea subiectivă de bine a angajaţilor şi se soldează cu stări emoţionale preponderent negative. Astfel, organizaţiile vor fi cu atât mai atractive pentru angajaţi, cu cât le oferă posibilităţi să integreze solicitările legate de locul de muncă şi cele din familie. Cum este perceput angajamentul de rol şi „conflictul familie-muncă” la angajaţii din Republica Moldova, precum şi felul în care interferează solicitările de roluri sunt aspecte pe care le vom discuta în acest context.PERCEPTIONS REGARDING ROLE COMMITMENT AND WORK-FAMILY CONFLICT OF THE EMPLOYEES FROM THE REPUBLIC OF MOLDOVA: EXPLORATIVE STUDYOne of the motivational conflicts often encountered in the organizational environment is "family-work conflict." The conflict, in this case, derives from the need to integrate optimally family and work-related responsibilities. Studies show that this type of conflict is a source of considerable distress for both employees and the organization; it affects the subjective well-being of employees and results in predominantly negative emotions. Thus, organizations will be more attractive for workers if they can provide opportunities to integrate tasks related to work and family. We will discuss hereby how role commitments and "family-work conflicts" are perceived by employees in RM and the way these multiple roles interfere.

Another task was the work on the surroundings (only partially carried out, which included, for example, reorienting the approach lo the grounds and lo the building -with the basic idea that Gaudi´s work should dominate the eye of the approaching visitor-the stone paving in the immediate vicinity of the church, bearing in mind the character; significance and use of the building, or the access to the new terrace, designed lo allow visitors lo discover completely new perspectives and perceptions.La intervención en las fachadas y el entorno de la iglesia de la Colonia Güell, promovida por el Ministerio de Educación, Cultura y Deporte, finalizó en mayo de 2003.

The U.S. Geological Survey (USGS) is monitoring and analyzing glacial-lake outburst floods (GLOFs) in the Colonia valley in the Patagonia region of southern Chile. A GLOF is a type of flood that occurs when water impounded by a glacier or a glacial moraine is released catastrophically. In the Colonia valley, GLOFs originating from Lago Cachet Dos, which is dammed by the Colonia Glacier, have recurred periodically since 2008. The water discharged during these GLOFs flows under or through the Colonia Glacier, into Lago Colonia and then the Río Colonia, and finally into the Río Baker—Chile's largest river in terms of volume of water.

Con objeto de explicar esta aparente paradoja, el artículo analiza la forma en que la Cadiz Factory contribuyó a la expansión comercial e imperial británica en un periodo caracterizado por el reforzamiento de los lazos entre los mundos atlántico, mediterráneo y asiático.

Full Text Available En este artículo reconstruyo el proceso por medio del cual el vocablo "colonia" adquirió calidad de concepto sociopolítico a lo largo del siglo xviii en relación con las reformas borbónicas, el ascenso del absolutismo, las revoluciones atlánticas (incluyendo, de manera particular, sus dos variantes americanas: la norteamericana y la haitiana, la emergencia de un imaginario republicano y el fortalecimiento de las elites criollas. Al contrario de lo que podría pensarse, la noción evaluativa descriptiva de "colonia" no era conceptualmente ajena a los agentes del antiguo régimen y del nuevo orden sociopolítico. Aun más, el problema colonial era central para la cultura política del período en tanto designaba una experiencia de negatividad política que hacían suya en ese momento y desde la cual se hacía necesario y urgente pensar la fundación de una nueva soberanía.In this article I reconstruct the process by which the term "colony" became a socio-political concept towards the end of the eighteenth century, a process which took place in connection with the Bourbon reforms, the rise of absolutism, the Atlantic revolutions (including the North American and the Haitian, the emergence of a Republican imaginary and the strengthening of local elites. Contrary to widespread belief, the descriptive evaluative notion of "colony" was not alien to late 18th century American intellectual elites. Furthermore, such defi nitions of the colonial experience became central to the political culture of the period by designating an experience of political negativity from which it became necessary and urgent to think and refl ect upon the foundation of a new sovereignty.

In Nogales, Sonora, Mexico, some neighborhoods, or colonias, have intermittent delivery of water through pipes from the city of Nogales's municipal water-delivery system while other areas lack piped water and rely on water delivered by truck or pipas. This research examined how lifestyles, water quality, and potential disease response, such as diarrhea, differs seasonally from a colonia with access to piped water as opposed to one using alternative water-delivery systems. Water samples were collected from taps or spigots at homes in two Nogales colonias. One colonia reflected high socio-environmental conditions where residents are supplied with municipal piped water (Colonia Lomas de Fatima); the second colonia reflected low socio-environmental conditions, lacking access to piped water and served by pipas (Colonia Luis Donaldo Colosio). A survey was developed and implemented to characterize perceptions of water quality, health impacts, and quality of life. Water samples were analyzed for microbial and inorganic water-quality parameters known to impact human health including, Escherichia coli (E. coli), total coliform bacteria, arsenic, and lead. A total of 21 households agreed to participate in the study (14 in Colosio and 7 in Fatima). In both colonias metal concentrations from water samples were all well below the United States Environmental Protection Agency's (US EPA's) maximum contaminant levels. E. coli concentrations exceeded the US EPA's drinking-water standard in Colosio but not Fatima. Total coliform bacteria were present in over 50 % of households in both colonias. Microbial contamination was significantly higher in the summer than in the winter in both colonias. Resulting analysis suggests that residents in colonias without piped water are at a greater risk of gastrointestinal illness from consumption of compromised drinking water. Our survey corroborated reports of gastrointestinal illness in the summer months but not in the winter. Chloride was found

This study sheds light on the role that the competitive environment plays in determining how elements of market orientation and elements of entrepreneurial orientation interact to influence business success. We develop a model in which we postulate that market orientation, entrepreneurial...... orientation, and competitive environment shape business performance via a three-way interaction. We test the model using primary data from the CEOs of 270 CEO of manufacturing firms, together with secondary data on these firms' profit performance. An assessment of the results indicates that customer...... orientation moderates the positive relationships between the competitiveness element of entrepreneurial orientation and market share and return on assets (ROA): the positive relationships between competitiveness and market share and competitiveness and ROA become stronger the greater the firms' customer...

The relationships between different behavioural aspects of political market orientation and the attitudinal influences of such behaviour are analysed, and the study includes structural equation...... modelling to test several hypotheses. While the results show that political parties focus on several different aspects of market-oriented behaviour, especially using an internal and societal orientation as cultural antecedents, a more surprising result is the inconclusive effect of a voter orientation...... on political market orientation. This lends support to the argument of 'looking beyond the customer' in political marketing research and practice. The article discusses the findings in the context of the existing literature on political marketing and commercial market orientation....

[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.

En Uruguay la única especie detectada es N. ceranae. Para determinar si la incidencia de N. ceranae en las colonias tiene un componente genético se realizó una selección bidireccional para aumento de la resistencia y la susceptibilidad a este parásito sin control de la paternidad. Las colonias fueron evaluadas en una forestación de Eucalyptus grandis en otoño. La infección de las colonias se determinó como 1 el porcentaje de abejas pecoreadoras infectadas y 2 el número promedio de esporas por campo en 10 campos. El trabajo se inició con 138 colonias y se evaluaron dos generaciones de 30 y 63 colonias. La respuesta a la selección fue muy limitada, solo en la primera generación las colonias de la línea resistente presentaron menos esporas por abejas que las colonias de la línea susceptible (19,6 ± 5,8 y 26,8 ± 10,4, respectivamente, W = 41,5; P = 0.03. Esto indicaría que la resistencia a la nosemosis está fuertemente afectada por el ambiente. Futuros esfuerzos para aumentar la resistencia de las abejas a N. ceranae a través de mejora genética deberán incluir el control de la paternidad.

Subcortical orientation biases explain orientation selectivity of visual cortical cells.

Science.gov (United States)

Vidyasagar, Trichur R; Jayakumar, Jaikishan; Lloyd, Errol; Levichkina, Ekaterina V

2015-04-01

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.

The rotating orientation x-ray diffraction (RO-XRD) method, based on conventional XRD instruments by a modification of the sample stage, was introduced to investigate the orientation-related issues of such materials. 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)

1992-01-01

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.

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.

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.

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.

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.

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.

To determine the extent to which neighborhood needs (socioeconomic deprivation and vehicle availability) are associated with two criteria of food environment access: 1) distance to the nearest food store and fast food restaurant and 2) coverage (number) of food stores and fast food restaurants within a specified network distance of neighborhood areas of colonias, using ground-truthed methods. Data included locational points for 315 food stores and 204 fast food restaurants, and neighborhood characteristics from the 2000 U.S. Census for the 197 census block group (CBG) study area. Neighborhood deprivation and vehicle availability were calculated for each CBG. Minimum distance was determined by calculating network distance from the population-weighted center of each CBG to the nearest supercenter, supermarket, grocery, convenience store, dollar store, mass merchandiser, and fast food restaurant. Coverage was determined by calculating the number of each type of food store and fast food restaurant within a network distance of 1, 3, and 5 miles of each population-weighted CBG center. Neighborhood need and access were examined using Spearman ranked correlations, spatial autocorrelation, and multivariate regression models that adjusted for population density. Overall, neighborhoods had best access to convenience stores, fast food restaurants, and dollar stores. After adjusting for population density, residents in neighborhoods with increased deprivation had to travel a significantly greater distance to the nearest supercenter or supermarket, grocery store, mass merchandiser, dollar store, and pharmacy for food items. The results were quite different for association of need with the number of stores within 1 mile. Deprivation was only associated with fast food restaurants; greater deprivation was associated with fewer fast food restaurants within 1 mile. CBG with greater lack of vehicle availability had slightly better access to more supercenters or supermarkets, grocery

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

Science.gov (United States)

Alink, Arjen; Krugliak, Alexandra; Walther, Alexander; Kriegeskorte, Nikolaus

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

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.

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

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

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

Market Orientation and Innovators’ Success: an Exploration of the Influence of Customer and Competitor Orientation

Directory of Open Access Journals (Sweden)

Michael Lewrick

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.

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

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

Grenvillean sutures zones in the northern portion of the Cuyania terrane, Republica Argentina. geophysical evidence

International Nuclear Information System (INIS)

Chernicoff, C.; Vujovich, G.

2004-01-01

In the northern portion of the Cuyania terrane there is geophysical evidence for the ocurrence of two ancient WNW suture zones, corresponding to the Guandacol and Vinchina lineaments. The location of these sutures is consistent with analogous structures in Laurentia, in the Ouachita embayment region, where the Grenvillean orogen trends WNW. It is argued that the WNW transform faults pertaining to the Ouachita rift would have developed as a result of a reactivation of compressional structures of identical orientation associated to the accretion of Grenvillean terranes. The Guandacol and Vinchina lineaments would have been in physical continuity with analogous megastructures in the Ouachita embayment region, and they both would have originated as compressional structures, later reactivated as transcurrent fault zones during the late Proterozoic early Paleozoic. The interpretation of the Guandacol and Vinchina lineaments as Grenvillean suture zones would add more complexity to the Cuyania terrane, with respect to what has been described up to now; they could precede the amalgamation of the Pie de Palo and Precordillera terranes (constituents of the Cuyania composite terrane) [es

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.

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

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.

Dynamics of market orientation in Croatian economy

Ivana First

2011-12-01

Full Text Available It was the goal of this research to examine the dynamics of Croatian transformation to market orientation and test whether the market orientation model changes with time as the business environment changes. Based on the literature analysis, we proposed a hypothetical model which relies on behavioural approach in understanding market orientation. 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

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.

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

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

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.

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.

Dermatoglyphics, handedness, sex, and sexual orientation.

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.

An object-oriented approach to energy-economic modeling

Energy Technology Data Exchange (ETDEWEB)

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.

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.

Full Text Available Este artículo se propone analizar un juicio de residencia, llevado a cabo en los años 1775 y 1776 en la gobernación de Tucumán, como un ritual político. Entendemos que, al teatralizar una forma ideal de funcionamiento de las instituciones y comportamiento de los funcionarios, el juicio de residencia como ritual político actuaba fortaleciendo el poder monárquico en las colonias, transmitiendo un conjunto de valores y congregando y cohesionando a la comunidad local. Partiendo de esta perspectiva ritual, abordamos el problema de la tensión existente entre las normas y objetivos que ordenaban la institución de la residencia y las implicancias y consecuencias que, en la práctica, acarreaba su celebración.This article analyzes an impeachment proceeding that took place in 1775-1776 in colonial Tucumán, in terms of a political ritual. We understand that by performing the ideal way of government institution's operation and officials' behaviour, the impeachment proceeding acted as a political ritual, reinforcing monarchical power in the colonies, transmitting a set of social values and congregating the local community. From this ritual perspective, we approach the problem of the tension between the norms and aims of the impeachment procedure, and the consequences and implications of its practice.

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.

Gender role, sexual orientation and suicide risk.

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

Sergey I. Kudinov

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.

Rapert, M I; Yarbrough, L

1997-01-01

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.

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

International Nuclear Information System (INIS)

Zhu Xiang; Farrer, Richard A; Zhong Qin; Fourkas, John T

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

In line with our group's intention of producing software using, where possible, Object-Oriented methodologies and techniques in the development of RF control systems, we have undertaken three projects to enhance the EPICS software environment. Two of the projects involve interfaces to EPICs Channel Access from Object-Oriented languages. The third is an enhancement to the EPICS State Notation Language to better support the Shlaer-Mellor Object-Oriented Analysis and Design Methodology. This paper discusses the motivation, approaches, results and future directions of these three projects.

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

Hails from the crypt: a terror management health model investigation of the effectiveness of health-oriented versus celebrity-oriented endorsements.

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

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

2018-03-05

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.

Science.gov (United States)

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.

Simon, E W; Dixon, R A; Nowak, C A; Hultsch, D F

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

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

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.)

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.

Full Text Available Durante el siglo XVII los sucesivos reyes de Castilla y Aragón habían perdido parte del control político y económico de sus colonias americanas. Esta circunstancia favoreció el florecimiento económico y social de las colonias y la conformación de élites locales que tenían cierta influencia en la administración colonial. La situación cambió a lo largo del siglo XVIII con la llegada de los Borbones1, que tomaron medidas para aumentar el control político y económico de la metrópoli sobre las posesiones de ultramar. La política colonial de Carlos III, inspirada en el despotismo ilustrado, buscó generar modificaciones “desde arriba” sin cambiar las relaciones sociales2. Entre las principales Reformas Borbónicas se encuentra la creación del Virreinato del Río de la Plata (1776, que transformó a Buenos Aires en la nueva sede de gobierno. El mismo estaba constituido por parte de los territorios de los siguientes países actuales: Bolivia (Alto Perú, Paraguay, Uruguay (Banda Oriental y Argentina. Uno de los principales objetivos era frenar el contrabando a favor del monopolio mercantil de la metrópoli, dado que por el lejano puerto de Buenos Aires se producía un comercio ilegal3, con la salida de metales preciosos altoperuanos y la entrada de esclavos y productos manufacturados europeos introducidos por ingleses4 y portugueses5.

Zhitnikov, R.

1979-01-01

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. (J.U.)

Performance-oriented: toward a successful strategy.

Kumar, K; Subramanian, R; Yauger, C

Changes in the health care industry have profoundly affected hospital management and have caused severe declines in hospital profitability. In 1993, Health Care Management Review reported that the average operating profit margin, around 2% in 1984, had declined to a 0.2% loss by 1990. 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

Directory of Open Access Journals (Sweden)

Mini M.G.

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.

Strong oriented chromatic number of planar graphs without short cycles

Directory of Open Access Journals (Sweden)

Mickaël Montassier

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.

Test anxiety, perfectionism, goal orientation, and academic performance.

Eum, KoUn; Rice, Kenneth G

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

Directory of Open Access Journals (Sweden)

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

International Nuclear Information System (INIS)

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

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.

Market orientation is usually regarded as something, which characterises a company. 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.

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

2016-08-01

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.

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.

[Vocational orientation in medical rehabilitation: development of a practice handbook and a homepage as user-oriented media for rehabilitative practice].

Lukasczik, M; Löffler, S; Gerlich, C; Wolf, H-D; Neuderth, S

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

G. Nwokah

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.

In Uruguay, colonies of honey bees moving to Eucalyptus grandis plantation in autumn habitually become infected with the microsporidian Nosema ceranae , a parasite that attacks the digestive system of bees. Beekeepers attributed to N. ceranae depopulation of the colonies that often occurs at the end of the blooming period, and many use the antibiotic fumagillin to reduce the level of infection. The aim of this study was to compare the effectiveness of four different fumagillin treatments and determine how this antibiotic affects the strength of the colonies during the winter season. The colonies treated with fumagillin in July showed less spore load at the end of applications, being the most effective the following treatments: the four applications sprayed over bees of 30 mg of fumagillin in 100 ml of sugar syrup 1:1, and four applications of 90 mg of fumagillin in 250 ml of sugar syrup 1:1 using a feeder. However, 2 month after the treatment applications, the colonies treated with fumagillin were the same size as the untreated colonies. In September, the colonies treated and not treated with fumagillin did not differ in colony strength (adult bee population and brood area) or spores abundance. Our study demonstrates that fumagillin treatment temporarily decreased the spore load of N. ceranae , but this was not reflected in either the size of the colonies or the probability of surviving the winter regardless of the dose or the administration strategy applied. Given the results obtained, we suggest to not perform the pharmacological treatment under the conditions described in the experiment. En Uruguay las colonias de abejas melíferas que se trasladan a las forestaciones de Eucalyptus grandis en otoño indefectiblemente se infectan con el microsporido Nosema ceranae , parásito que ataca el sistema digestivo de las abejas.

Minireview: Hormones and human sexual orientation.

Science.gov (United States)

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

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.

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.

2017-10-01

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.

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.

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.

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

A total of 632 (349 boys, 283 girls) adolescent athletes (aged 13–18 years) completed the Sports Motivation Scale and Task and Ego Orientation in Sport Questionnaire. Results indicated significant differences between gender on intrinsic motivation, extrinsic motivation, amotivation (t(630) = 4.10, p motivation, extrinsic motivation, amotivation and ego orientation. A significant difference was found between age groups on task orientation (t(630) = 1.94, p motivation. Task orientation was related to intrinsic motivation (r = 0.55, p extrinsic motivation (r = 0.55, p motivation (r = 0.30, p extrinsic motivation (r = 0.36, p motivation, extrinsic motivation and amotivation accounted for 30.5% of the variances in task orientation.

Full Text Available En Colombia la fresa se ha convertido en un cultivo de interés económico debido a la creciente demanda en el mercado extranjero en la última década. La mayoría de plantaciones son a campo abierto y no usan esquemas de polinización para mejorar la calidad de producción. La polinización con abejorros mejora la calidad de los frutos, aunque estos se producen mediante polinización espontánea. La especie nativa Bombus atratus ha sido reconocida como un polinizador eficiente de cultivos hortofrutícolas colombianos bajo invernadero. El presente estudio evaluó la eficiencia de polinización de dos colonias huérfanas en la calidad de los frutos de las variedades camino real y ventana sembrados bajo invernadero en Cajicá-Colombia. Se embolsaron los botones para obtener los frutos producidos espontáneamente y ser comparados con los frutos provenientes de la visita de obreras de B. atratus. Se encontró que la visita de las obreras mejoró la calidad de los frutos en las variables, calibre (35 % y 31 %, longitud (28 % y 19 %, peso fresco (103 % y 90 %, peso seco (126 % y 145 % y número de semillas (55 % y 81 % para las variedades Camino Real y Ventana respectivamente. A partir de las observaciones realizadas, se determinó que el recurso floral utilizado por las obreras de B. atratus fue el néctar y se hacen recomendaciones sobre su uso en este cultivo.

Orientation is a fundamental mental function that processes the relations between the behaving self to space (places), time (events), and person (people). Behavioral and neuroimaging studies have hinted at interrelations between processing of these three domains. To unravel the neurocognitive basis of orientation, we used high-resolution 7T functional MRI as 16 subjects compared their subjective distance to different places, events, or people. Analysis at the individual-subject level revealed cortical activation related to orientation in space, time, and person in a precisely localized set of structures in the precuneus, inferior parietal, and medial frontal cortex. Comparison of orientation domains revealed a consistent order of cortical activity inside the precuneus and inferior parietal lobes, with space orientation activating posterior regions, followed anteriorly by person and then time. Core regions at the precuneus and inferior parietal lobe were activated for multiple orientation domains, suggesting also common processing for orientation across domains. The medial prefrontal cortex showed a posterior activation for time and anterior for person. Finally, the default-mode network, identified in a separate resting-state scan, was active for all orientation domains and overlapped mostly with person-orientation regions. These findings suggest that mental orientation in space, time, and person is managed by a specific brain system with a highly ordered internal organization, closely related to the default-mode network.

Full Text Available Orientation plays a vital role for organizations to compete to create sustainable competitive advantage. The objective of this study is to examine the relationship between market orientation (MO and organizational performance (OP with service quality (SQ as a moderator in the context of the hotel industry in Malaysia. MO and OP were conceptualized as three- and two-dimensional constructs, respectively, whereas SQ, which consists of two-dimensional constructs, namely, technical quality and functional quality, was used as a moderator. Data were gathered through a survey using a structured questionnaire with a sample of 187 executive-level employees employed in hotels rated three stars and above in Malaysia. SmartPLS 2.0 (M3 with path modeling and bootstrapping was used to examine the standard error of the estimate and t-values. The findings suggest that only competitor orientation dimension of MO was significantly related to OP, whereas customer orientation and inter-functional coordination were not related. Interestingly, SQ was found to have moderated the relationship between MO and performance of the hotels in Malaysia. SQ exists to fill in the gap between customers’ expectations and their perception of the service providers’ performance that further creates differentiation and competitive advantage, which enhance MO practices and ultimately lead to improvements in the firm’s performance. Implications of the findings, potential limitations of the study, and directions for future research are highlighted.

Using anodic aluminum oxide membranes as the nanoreactors and controller, oriented nanowire arrays of the diluted magnetic semiconductor Mn-doped CuO have been successfully fabricated using Mn(NO_3)_2 · 4H_2O and Cu(NO_3)_2 · 3H_2O as the starting materials. X-ray diffraction measurements showed that the as-prepared oriented nanowire arrays are of high purity. Scanning electron microscope and transmission electron microscope studies showed the nanowires are oriented, continuous and uniform with a diameter and length of about 170 nm and several tens of micrometers, respectively, and thus of a high aspect ratio. Low-temperature magnetic measurements showed the ferromagnetic property of the oriented Mn-doped CuO nanowire arrays with the critical temperature at around 80 K, which will endow them with great potential applications in spintronics in the future.

An experiment was performed that examined the impact of stimulus orientation on performance on the Rey complex figure. A total of 48 undergraduates (24 men, 24 women) were randomly assigned to one of four Rey figure orientation groups (0 degrees, 90 degrees, 180 degrees, and 270 degrees ). Participants followed standard procedures for the Rey figure, initially copying it in whatever orientation group they were assigned to. Next, all participants performed a 15-20 min lexical decision experiment, used as a filler task. Finally, and unbeknownest to them, participants were asked to recall as much of the figure as they could. As expected, results revealed a main effect of Task (F = 83.92, p orientation was not significant, nor did orientation interact with task (Fs .57). The results are important from an applied setting, especially if testing conditions are less than optimal and a fixed stimulus position is not possible (e.g., testing at the bedside).

A study with United States undergraduate students showed individuals high in concern with future consequences engage in exercise and healthy eating because they adopt a promotion orientation, which represents the extent to which individuals are inclined to pursue positive gains. The present article reports a cross-cultural replication of the mediation findings with undergraduate samples from Brazil and New Zealand. Promotion orientation mediated the association between concern with future consequences and exercise attitudes in both countries, but the associations for healthy eating were not replicated-which could be explained by distinct obesity prevalence and eating habits in these socio-cultural contexts. We discuss theoretical and practical implications of the findings for promoting health behavior.

Peltokoski, J; Vehviläinen-Julkunen, K; Miettinen, M

2016-03-01

This study aimed to describe the research on registered nurses' orientation processes in specialized hospital settings in order to illustrate directions for future research. The complex healthcare environment and the impact of nursing shortage and turnover make the hospital orientation process imperative. There is a growing recognition regarding research interests to meet the needs for evidence-based, effective and economically sound hospital orientation strategies. An integrative literature review was performed on publications from the period 2000 to 2013 included in the CINAHL and PubMed databases. English-language studies were included. Themes guiding the analysis were definition of the hospital orientation process, research topics, data collection and instruments and research evidence. Narrative synthesis was used. Eleven papers met the inclusion criteria. The conceptualization of orientation process reflected the complexity of the phenomenon. Less attention has been paid to designs to establish correlations or relationships between selected variables and hospital orientation process. The outcomes of hospital orientation programmes were limited primarily to retention and job satisfaction. The research evidence therefore cannot be evaluated as strong. The lack of an evidence-based approach makes it difficult to develop a comprehensive orientation process. Further research should explore interventions that will enhance the quality of hospital orientation practices to improve nurses' retention and job satisfaction. To provide a comprehensive hospital orientation process, hospital administrators have to put in place human resource development strategies along with practice implications and research efforts. Comprehensive hospital orientation benefits and outcomes should be visible to policy makers. © 2016 International Council of Nurses.

Ureter smooth muscle cell orientation in rat is predominantly longitudinal.

Directory of Open Access Journals (Sweden)

Bart Spronck

Full Text Available In ureter peristalsis, the orientation of the contracting smooth muscle cells is essential, yet current descriptions of orientation and composition of the smooth muscle layer in human as well as in rat ureter are inconsistent. The present study aims to improve quantification of smooth muscle orientation in rat ureters as a basis for mechanistic understanding of peristalsis. A crucial step in our approach is to use two-photon laser scanning microscopy and image analysis providing objective, quantitative data on smooth muscle cell orientation in intact ureters, avoiding the usual sectioning artifacts. In 36 rat ureter segments, originating from a proximal, middle or distal site and from a left or right ureter, we found close to the adventitia a well-defined longitudinal smooth muscle orientation. Towards the lamina propria, the orientation gradually became slightly more disperse, yet the main orientation remained longitudinal. We conclude that smooth muscle cell orientation in rat ureter is predominantly longitudinal, though the orientation gradually becomes more disperse towards the proprial side. These findings do not support identification of separate layers. The observed longitudinal orientation suggests that smooth muscle contraction would rather cause local shortening of the ureter, than cause luminal constriction. However, the net-like connective tissue of the ureter wall may translate local longitudinal shortening into co-local luminal constriction, facilitating peristalsis. Our quantitative, minimally invasive approach is a crucial step towards more mechanistic insight into ureter peristalsis, and may also be used to study smooth muscle cell orientation in other tube-like structures like gut and blood vessels.

Neurobiology of Gender Identity and Sexual Orientation.

Roselli, Charles E

2017-12-06

Sexual identity and sexual orientation are independent components of a person's sexual identity. These dimensions are most often in harmony with each other and with an individual's genital sex, but not always. This review discusses the relationship of sexual identity and sexual orientation to prenatal factors that act to shape the development of the brain and the expression of sexual behaviors in animals and humans. One major influence discussed relates to organizational effects that the early hormone environment exerts on both gender identity and sexual orientation. Evidence that gender identity and sexual orientation are masculinized by prenatal exposure to testosterone and feminized in it absence is drawn from basic research in animals, correlations of biometric indices of androgen exposure and studies of clinical conditions associated with disorders in sexual development. There are, however, important exceptions to this theory that have yet to be resolved. Family and twin studies indicate that genes play a role, but no specific candidate genes have been identified. Evidence that relates to the number of older brothers implicates maternal immune responses as a contributing factor for male sexual orientation. It remains speculative how these influences might relate to each other and interact with postnatal socialization. Nonetheless, despite the many challenges to research in this area, existing empirical evidence makes it clear that there is a significant biological contribution to the development of an individual's sexual identity and sexual orientation.

Beam-orientation customization using an artificial neural network

Rowbottom, C.G.; Webb, S.; Oldham, M.

1999-01-01

A methodology for the constrained customization of coplanar beam orientations in radiotherapy treatment planning using an artificial neural network (ANN) has been developed. The geometry of the patients, with cancer of the prostate, was modelled by reducing the external contour, planning target volume (PTV) and organs at risk (OARs) to a set of cuboids. The coordinates and size of the cuboids were given to the ANN as inputs. A previously developed beam-orientation constrained-customization (BOCC) scheme employing a conventional computer algorithm was used to determine the customized beam orientations in a training set containing 45 patient datasets. Twelve patient datasets not involved in the training of the artificial neural network were used to test whether the ANN was able to map the inputs to customized beam orientations. Improvements from the customized beam orientations were compared with standard treatment plans with fixed gantry angles and plans produced from the BOCC scheme. The ANN produced customized beam orientations within 5 deg. of the BOCC scheme in 62.5% of cases. The average difference in the beam orientations produced by the ANN and the BOCC scheme was 7.7 deg. (±1.7, 1 SD). Compared with the standard treatment plans, the BOCC scheme produced plans with an increase in the average tumour control probability (TCP) of 5.7% (±1.4, 1 SD) whilst the ANN generated plans increased the average TCP by 3.9% (±1.3, 1 SD). Both figures refer to the TCP at a fixed rectal normal tissue complication probability (NTCP) of 1%. In conclusion, even using a very simple model for the geometry of the patient, an ANN was able to produce beam orientations that were similar to those produced by a conventional computer algorithm.

Hannon, Michael D; Hannon, LaChan V

2017-07-01

Sixteen fathers of individuals with autism were interviewed to develop a grounded theory explaining how they learned about their children's autism diagnosis. Results suggest the orientation process entails at least two phases: orienting oneself and orienting others. The orienting oneself phase entailed fathers having suspicion of developmental differences, engaging in research and education activities, having their children formally evaluated; inquiring about their children's prognosis, and having curiosities about autism's etiology. The orienting others phase entailed orientating family members and orienting members of their broader communities. Recommendations for responsive service provision, support for fathers, and future research are offered.

Sexual Orientation as Interpretation? Sexual Desires, Concepts, and Choice

Directory of Open Access Journals (Sweden)

Díaz-León E.

2017-07-01

Full Text Available Are sexual orientations freely chosen? The idea that someone’s sexual orientation is not a choice is very influential in the mainstream LGBT political movement. But do we have good reasons to believe it is not a choice? Going against the orthodoxy, William Wilkerson has recently argued that sexual orientation is partly constituted by our interpretations of our own sexual desires, and we choose these interpretations, so sexual orientation is partly constituted by choice. In this paper I aim to examine the question of whether our interpretations of our own sexual desires are constitutive of our sexual orientations. I will argue that whereas Wilkerson’s argument for the claim that sexual orientations are in part constituted by our chosen interpretations of our sexual desires is not sound, there are good reasons for endorsing a weaker claim, namely, that there are different but equally apt descriptions of the same sexual desires, depending on which concepts we have.

Nano-scale orientation mapping of graphite in cast irons

2014-01-01

A diametrical section of a graphite spheroid from a ductile iron sample was prepared using the focused ion beam-lift out technique. Characterization of this section was carried out through automated crystal orientation mapping in a transmission electron microscope. This new technique automatically collects electron diffraction patterns and matches them with precalculated templates. The results of this investigation are crystal orientation and phase maps of the specimen, which bring new light to the understanding of growth mechanisms of this peculiar graphite morphology. This article shows that mapping the orientation of carbon-based materials such as graphite, which is difficult to achieve with conventional techniques, can be performed automatically and at high spatial resolution using automated crystal orientation mapping in a transmission electron microscope. - Highlights: • ACOM/TEM can be used to study the crystal orientation of carbon-based materials. • A spheroid is formed by conical sectors radiating from a central nuclei. • Misorientations exist within the conical sectors, defining various orientation domains

EFL Teachers’ Epistemological Beliefs and Their Assessment Orientations

Full Text Available Epistemological beliefs—beliefs about the nature of knowledge, where it resides, and how knowledge is constructed and evaluated—have been the target of increased research interest lately. Heretofore, emphasis has been directed to language teaching/learning aspects and strategies. Language assessment practices have not yet received due attention in epistemic research literature. The current study examined the relationship between pre-service EFL teachers’ epistemological beliefs and their assessment orientations. Dimensions of epistemological beliefs were assessed via a questionnaire designed and validated by the researcher based on Schommer’s work. Two assessment orientations were examined including: (a transmissive surface- processing orientation and (b constructive deep-processing orientation. The study involved 114 preservice EFL teachers enrolled in the Professional Diploma in Teaching Program in the Abu Dhabi University, the United Arab Emirates. Results of the study showed that EFL teachers’ epistemological beliefs have a direct bearing on their assessment orientations and practices. EFL teachers with naive epistemological beliefs tended more to adopt surface-level assessment orientations whereas those with sophisticated epistemological beliefs showed more tendency to adopt deeper level approaches to assessment in language settings. Results are discussed in terms of backwash effects on foreign language instruction, curriculum development, and teacher education. Suggestions for further research are also discussed.

Depicting the Orient in Wilkie Collins’ The Moonstone

Directory of Open Access Journals (Sweden)

Amna Matar Al-Neyadi

2015-11-01

Full Text Available Nineteenth century Britain witnessed an increased interest with the Orient, largely as a result of the imperial expansion that reached its peak during that time. India was one of the main Oriental interests of the Victorians because of the political, commercial, religious and scientific passion of the nineteenth century people in India. For that reason, various Victorian authors who wrote about India were mostly characterized as being orientalist and writing in a biased way. One such example of this was Joseph Rudyard Kipling. This, as Edward Said explains, was because nineteenth century writers were aware of the empire’s authority. However, I propose that Wilkie Collins tended to have a positive attitude towards the Orient in his novel The Moonstone and towards the Brahmins specifically, which is an attitude that deviates from what is currently known about him. To argue this, the paper will analyse the narrative techniques and the reflection of some of the characters’ attitudes towards the Orient that Collins adopts in his novel in order to allow Victorian readers to challenge the stereotyped beliefs of the Orient. It will also comment on Collins’s employment of the sensational sub-genre particularly to draw his own attitude of the Orient.

Observation of changing crystal orientations during grain coarsening

2012-01-01

Understanding the underlying mechanisms of grain coarsening is important in controlling the properties of metals, which strongly depend on the microstructure that forms during the production process or during use at high temperature. Grain coarsening of austenite at 1273 K in a binary Fe–2 wt.% Mn alloy was studied using synchrotron radiation. Evolution of the volume, average crystallographic orientation and mosaicity of more than 2000 individual austenite grains was tracked during annealing. It was found that an approximately linear relationship exists between grain size and mosaicity, which means that orientation gradients are present in the grains. The orientation gradients remain constant during coarsening and consequently the character of grain boundaries changes during coarsening, affecting the coarsening rate. Furthermore, changes in the average orientation of grains during coarsening were observed. The changes could be understood by taking the observed orientation gradients and anisotropic movement of grain boundaries into account. Five basic modes of grain coarsening were deduced from the measurements, which include: anisotropic (I) and isotropic (II) growth (or shrinkage); movement of grain boundaries resulting in no change in volume but a change in shape (III); movement of grain boundaries resulting in no change in volume and mosaicity, but a change in crystallographic orientation (IV); no movement of grain boundaries (V).

Parental selection of children's sexual orientation.

Science.gov (United States)

Greenberg, A S; Bailey, J M

2001-08-01

As we learn more about the causes of sexual orientation, the likelihood increases that parents will one day be able to select the orientation of their children. This possibility (at least that of selecting for heterosexuality) has generated a great deal of concern among supporters of homosexual rights, with such selection being widely condemned as harmful and morally repugnant. Notwithstanding this widespread condemnation, and even assuming, as we do, that homosexuality is entirely acceptable morally, allowing parents, by means morally unproblematic in themselves, to select for heterosexuality would be morally acceptable. This is because allowing parents to select their children's sexual orientation would further parent's freedom to raise the sort of children they wish to raise and because selection for heterosexuality may benefit parents and children and is unlikely to cause significant harm.

A piece of software is today conceived, constructed and tested as a set of objects interacting with each other, rather than as a large sequential program. OO is present throughout the whole software life cycle allowing for maintainable code re-use, clean design and manageable complexity. OO is also the seed upon which other technologies are being built and deployed, such as distributed computing, component models, open interoperability, etc.This series of three seminars will provide a pragmatic overview on the main ideas behind OO software development and will explain the inner workings of the most outstanding technologies being built on OO, such as UML, CORBA, Component Models, Agent Oriented Computing, Business Objects, etc.

Self-Orientalization: Modernity Within Ourselves or Internalized Modernization

After Said’s concept of orientalism had been widely recognized within political literature, this term has developed its content productively to explain Eastern Societies’ relation with modernity. Rather than being used in terms of East-West dichotomy, the term has gained new meanings as self-orientalization of Eastern Societies. In this study, the first section analyzes boundaries of the term. The second section discusses world of meaning’s locational scope of self-orientalization through nat...

Interlimb Transfer of Grasp Orientation is Asymmetrical

Full Text Available One the most fundamental aspects of the human motor system is the hemispheric asymmetry seen in behavioral specialization. Hemispheric dominance can be inferred by a contralateral hand preference in grasping. Few studies have considered grasp orientation in the context of manual lateralization and none has looked at grasp orientation with natural prehension. Thirty right-handed adults performed precision grasps of a cylinder using the thumb and index fingers, and the opposition axis (OA was defined as the line connecting these two contact points on the cylinder. Subjects made ten consecutive grasps with one hand (primary hand movements followed by ten grasps with the other hand (trailing movements. Differences between primary and trailing grasps revealed that each hemisphere is capable of programming the orientation of the OA and that primary movements with the right hand significantly influenced OA orientation of the trailing left hand. These results extend the hemispheric dominance of the left hemisphere to the final positions of fingers during prehension.

Humanoid Robotics: Real-Time Object Oriented Programming

Newton, Jason E.

2005-01-01

Programming of robots in today's world is often done in a procedural oriented fashion, where object oriented programming is not incorporated. In order to keep a robust architecture allowing for easy expansion of capabilities and a truly modular design, object oriented programming is required. However, concepts in object oriented programming are not typically applied to a real time environment. The Fujitsu HOAP-2 is the test bed for the development of a humanoid robot framework abstracting control of the robot into simple logical commands in a real time robotic system while allowing full access to all sensory data. In addition to interfacing between the motor and sensory systems, this paper discusses the software which operates multiple independently developed control systems simultaneously and the safety measures which keep the humanoid from damaging itself and its environment while running these systems. The use of this software decreases development time and costs and allows changes to be made while keeping results safe and predictable.

Cross-sectional study. To evaluate the association between lumbar spine facet joint orientation, facet joint tropism, and spondylolysis identified by multidetector computed tomography (CT) in the community-based Framingham Heart Study. The association between lumbar spondylolysis and facet orientation and tropism remains unclear. This study was an ancillary project to the Framingham Heart Study. Three thousand five hundred twenty-nine participants of the Framingham Heart Study aged 40 to 80 years underwent multidetector CT imaging to assess aortic calcification. One hundred ninety-one subjects were included in this ancillary study. Facet joint features and spondylolysis were evaluated on CT scans. The final analyzed sample included 104 men with mean age 51.90+/-11.25 years and 84 women with mean age 53.61+/-10.20 years. The association between spondylolysis and facet orientation and tropism was examined using univariate and multivariate analyses. Spondylolysis was prevalent in 11.5% of the total population. chi2 test demonstrated a significant sex difference in prevalence of spondylolysis (P=0.0154), with almost 3 times higher prevalence among men. There was no statistically significant difference in facet orientation and continuous facet tropism between individuals with and without spondylolysis at the L5 level (P=0.49 to 0.91). After adjustment for age, sex, and body mass index, no significant association between the occurrence of spondylolysis and facet orientation and tropism was found. In the studied sample the prevalence of facet joint osteoarthritis was significantly higher in individuals with spondylolysis than in those without spondylolysis at both sides of L4-L5 spinal level (P=0.044 at the right side and P=0.003 at the left side) and at left side of L5-S1 level (P=0.038). We did not find an association between facet orientation, facet tropism, and spondylolysis. One of the possible explanations for this is that the high prevalence of facet joint

Copper (I) oxide (Cu 2 O) films were cathodically electrodeposited on Sn-doped indium oxide substrates. The influence of electrodeposition bath pH on grain orientation and crystallite shape was carefully re-examined using X-ray diffraction and scanning electron microscopy. In addition to the (100) and (111) preferred orientations identified in two previous sets of studies, as the bath pH was varied in the present study from ∼ 7.5 to ∼ 12, a third preferred orientation, (110), was identified in a narrow pH range, ∼ 9.4 to ∼ 9.9. A remarkable shift in the flat-band potential (spanning ∼ 500 mV) was measured in a non-aqueous electrolyte medium for the various Cu 2 O samples obtained from baths of varying pH

Both a same-sex sexual orientation and gender nonconformity have been linked with poorer well-being; however, sexual orientation and gender nonconformity are also correlated. It is, therefore, critical to investigate their independent contributions to well-being. Based on survey responses of 230 female and 245 male high school seniors, the present study is one of the first to provide empirical data on this topic. Both childhood and adolescent gender nonconformity were negatively related to well-being. In the same analyses, neither sexual orientation nor biological sex was a significant predictor of well-being. These results suggest that gender-atypical traits may be more relevant for psychological health than a same-sex sexual orientation. Both environmental and biological influences may account for these findings.

Dynamic Stark shift and alignment-to-orientation conversion

Kuntz, Matthew C.; Hilborn, Robert C.; Spencer, Alison M.

2002-01-01

We have observed alignment-to-orientation conversion in the (5d6p) 1 P state of atomic barium due to the combined effects of a static Zeeman shift and a dynamic Stark shift associated with the electric field of a pulsed laser beam. The measurements yield a value for the frequency-dependent tensor polarizability of the state in reasonable agreement with a simple perturbation theory calculation. With a tunable laser producing the dynamic Stark shift, we can both enhance the magnitude of the effect by tuning close to a resonance and reverse the sign of the orientation by tuning above or below the resonance. This method of producing an oriented atomic state is quite general, and with easily available field strengths can produce large orientations

Full Text Available This research investigates the adoption factors of smartphones focusing on the differences of smartphone and feature phone users. We used Technology Acceptance Model (TAM which incorporates service-oriented and device-oriented functional attributes as exogenous variables for a product-service system such as smartphones. In addition, Decision Tree (DT and customer surveys were conducted. As a study results, we found that the service-oriented functional attributes - ‘wireless internet’ and ‘mobile applications’ - affect the adoption of smartphones regardless of users. However, the DT results revealed that the more important factor is 'mobile applications' to smartphone users but 'wireless internet' for feature phone users. In conclusion, we discovered that a strategy emphasis on the service-oriented attributes is needed for the adoption of smartphones.

Finite-difference time domain (FDTD) solutions are first compared with the corresponding T-matrix results for light scattering by circular cylinders with specific orientations. The FDTD method is then utilized to study the scattering properties of horizontally oriented hexagonal ice plates at two wavelengths, 0.55 and 12 μm. The phase functions of horizontally oriented ice plates deviate substantially from their counterparts obtained for randomly oriented particles. Furthermore, we compute the phase functions of horizontally oriented ice crystal columns by using the FDTD method along with two schemes for averaging over the particle orientations. It is shown that the phase functions of hexagonal ice columns with horizontal orientations are not sensitive to the rotation about the principal axes of the particles. Moreover, hexagonal ice crystals and circular cylindrical ice particles have similar optical properties, particularly, at a strongly absorbing wavelength, if the two particle geometries have the same length and aspect ratio defined as the ratio of the radius or semi-width of the cross section of a particle to its length. The phase functions for the two particle geometries are slightly different in the case of weakly absorbing plates with large aspect ratios. However, the solutions for circular cylinders agree well with their counterparts for hexagonal columns

The shortage of critical care nurses and the service expansion of 2 intensive care units provided a unique opportunity to create a new model of critical care orientation. The goal was to design a program that assessed critical thinking, validated competence, and provided learning pathways that accommodated diverse experience. To determine the effect of a new model of critical care orientation on satisfaction, retention, turnover, vacancy, preparedness to manage patient care assignment, length of orientation, and cost of orientation. A prospective, quasi-experimental design with both quantitative and qualitative methods. The new model improved satisfaction scores, retention rates, and recruitment of critical care nurses. Length of orientation was unchanged. Cost was increased, primarily because a full-time education consultant was added. A new model for nurse orientation that was focused on critical thinking and competence validation improved retention and satisfaction and serves as a template for orientation of nurses throughout the medical center.

Feedforward connections are thought to be important in the generation of orientation-selective responses in visual cortex by establishing a bias in the sampling of information from regions of visual space that lie along a neuron's axis of preferred orientation. It remains unclear, however, which structural elements-dendrites or axons-are ultimately responsible for conveying this sampling bias. To explore this question, we have examined the spatial arrangement of feedforward axonal connections that link non-oriented neurons in layer 4 and orientation-selective neurons in layer 2/3 of visual cortex in the tree shrew. Target sites of labeled boutons in layer 2/3 resulting from focal injections of biocytin in layer 4 show an orientation-specific axial bias that is sufficient to confer orientation tuning to layer 2/3 neurons. We conclude that the anisotropic arrangement of axon terminals is the principal source of the orientation bias contributed by feedforward connections.

Assigning Main Orientation to an EOH Descriptor on Multispectral Images.

Li, Yong; Shi, Xiang; Wei, Lijun; Zou, Junwei; Chen, Fang

This paper proposes an approach to compute an EOH (edge-oriented histogram) descriptor with main orientation. EOH has a better matching ability than SIFT (scale-invariant feature transform) on multispectral images, but does not assign a main orientation to keypoints. Alternatively, it tends to assign the same main orientation to every keypoint, e.g., zero degrees. This limits EOH to matching keypoints between images of translation misalignment only. Observing this limitation, we propose assigning to keypoints the main orientation that is computed with PIIFD (partial intensity invariant feature descriptor). In the proposed method, SIFT keypoints are detected from images as the extrema of difference of Gaussians, and every keypoint is assigned to the main orientation computed with PIIFD. Then, EOH is computed for every keypoint with respect to its main orientation. In addition, an implementation variant is proposed for fast computation of the EOH descriptor. Experimental results show that the proposed approach performs more robustly than the original EOH on image pairs that have a rotation misalignment.

Institutional Assessment of Environmentally Oriented Subsoil Use

2017-06-01

Full Text Available The article solves two relevant problems related to the implementation of the institutional assessment of environmentally oriented subsoil use: 1 the definition of the ‘environmental security’ and 2 the determination of the development level of institutional bases of environmentally oriented subsoil use including the institutional capacity of subsoil use and institutional capacity of environmental security. The article shows an analysis of the existing definitions of “environmental security” and offers the own one. Despite the significant national and foreign experience in the institutional capacity assessment of various processes, there are still some difficulties in defining and measuring the institutional capacity. We eliminate these difficulties by employing 1 original factors, previously identified, and the content of the “institutional capacity” term; 2 quality characteristics for the institutional capacity assessment of the process regulated at the macroeconomic level, and 3 a consistent methodological tool for the institutional assessment of environmentally oriented subsoil use. The study is based on the hypothesis of the necessity of legal and discreet state intervention in the process of subsoil use. Therefore, we identify the evaluation indicator of state regulation in the environmentally oriented subsoil use as the institutional capacity level calculated by using the fuzzy-set theory. As a result, the institutional capacity levels of the environmentally oriented subsoil use have been defined for both the transport corridor «Arctic-Central Asia» and for the countries composing it. The obtained values of the assessment of institutional capacity levels of the environmentally oriented subsoil use can serve as a basis for identifying the vector of its increase

Orientation control of {100}-oriented epitaxial orthorhombic 0.07YO{sub 1.5}-0.93HfO{sub 2} films grown by pulsed laser deposition was investigated. To achieve in-plane lattice matching, indium tin oxide (ITO) and yttria-stabilized zirconia (YSZ) were selected as underlying layers. We obtained (100)- and (001)/(010)-oriented films on ITO and YSZ, respectively. Ferroelastic domain formation was confirmed for both films by X-ray diffraction using the superlattice diffraction that appeared only for the orthorhombic symmetry. The formation of ferroelastic domains is believed to be induced by the tetragonal–orthorhombic phase transition upon cooling the films after deposition. The present results demonstrate that the orientation of HfO{sub 2}-based ferroelectric films can be controlled in the same manner as that of ferroelectric films composed of conventional perovskite-type material such as Pb(Zr, Ti)O{sub 3} and BiFeO{sub 3}.
