Figuring the Transnational 'Child-to-be-adopted' : The Web as a Virtual Sociocultural Contact Zone for Intercountry Adoption  

DEFF Research Database (Denmark)

This paper presents our research which is part of a larger project that explores how to track and understand the linguistic, discursive and sociocultural contact zones or networks brought about by intercountry adoption. Using mediated discourse analysis, critical discourse analysis, membership categorisation analysis and interaction analysis, the project attempts to trace a host of discourses and contingent practices of care and kinship that are heterogeneously assembled to ‘translate’ a child (legally and/or willingly) from one familial ‘place’ or network in the world to another, crossing linguistic, sociocultural, racial, class and national boundaries in the process. We introduce in this paper our first observations of the discursive construction of the ‘child-to-be-adopted’ in the pre-adoption stage. We focus on the crucial role of the ‘intimate public sphere’ of the Internet from the parents’ point-of-view, specifically their personal web pages and online diaries that anticipate the ‘transnational’ mobility of the ‘waiting’ or abandoned child in a faraway place.

The Consequences of Mobility : Linguistic and Sociocultural Contact Zones  

DEFF Research Database (Denmark)

The book is an anthology of articles investigating – from within four different theoretical and methodological perspectives – the kinds of linguistic and sociocultural contacts brought about by internationalization and transnational migrations in the contemporary world. It includes topics such as the following, related to this general interdisciplinary objective: • Language use in social networks, with special reference to language contact in interpersonal relations and interactions, including codeswitching and other manifestations of the construction of sociocultural identities in face-to-face interaction • Language contact in society and in the world, and social hierarchies between languages: consequences of (mobility driven) language spread, and the ensuing processes of redefining linguistic differences and identities: language competition, language promotion and language discrimination • The complex relationship between language and culture: how can we envisage mobility and language spread across cultural areas without conceptualizing language as culturally neutral? (cp. the frequent conceptualization of English as culturally neutral) • Language contact in the individual: multiple language competencies and the idea of plurilingualism - in Europe and in the world • The concept of linguaculture/languaculture, and studies related to this concept. • Language and sociocultural identity: how can we address this issue thinking both of first languages and of languages functioning as second and foreign languages? • The concepts of first language (mother tongue), second language, foreign language, and lingua franca: how can we develop and refine these analytical concepts taking into consideration the complexities of language contacts and plurilingual competencies?

El uso del campus virtual en el practicum de psicopedagogía: un enfoque constructivista y sociocultural  

Directory of Open Access Journals (Sweden)

Full Text Available En éste trabajo se presenta la organización y seguimiento del prácticum en el marco de una universidad virtual. Desde una visión constructivista y sociocultural de la enseñanza, del aprendizaje y de la evaluación, la propuesta plantea un modelo de prácticum de la licenciatura de 2º ciclo de Psicopedagogía,  que conjuga  la tutorización y el seguimiento del trabajo de los estudiantes en el centro de prácticas simultáneamente con un trabajo de reflexión sobre la práctica que se lleva a cabo en el aula del campus virtual. La aplicación de esta metodología aporta muchos beneficios formativos para los estudiantes puesto que garantiza la adquisición de destrezas propias de la intervención psicopedagógica en un contexto determinado conjuntamente con la reflexión sobre los contextos, finalidades y objetivos de la intervención psicopedagógica. Las repercusiones, ventajas e inconvenientes de éste modelo de prácticum se analizan teniendo en cuenta también las directrices del Espacio Europeo de Educación Superior.ABSTRACTUsing the virtual campus in the practicum of psychopedagogy: a socio-cultural and constructivist approach. The Practicum  (post-graduate teacher education) is an area critical to the formation of a student to finish college.In the new framework of European Higher Education Area(EHEA),classroom practices have become even more important for the development of the skills required for a particular professional profile. In this paper we present the organization and monitoring of the Practicum as part of a virtual university. From a constructivist and socio-cultural teaching, learning and assessment, the proposal presents a model of practicum of the degree of 2nd cycle of psychopedagogy, which combines mentoring and monitoring the work of students in the training center work simultaneously with a reflection on practice which takes place in the classroom of the virtual campus. The results are analyzed from the satisfaction questionnaire administered to students at the end of each semester, which assesses four areas: overall satisfaction, teaching activities, resources and assessment of learning. The application of this methodology has many benefits for students training as skill acquisition warrants intervention own psychology in context togetherwith reflection on the contexts, purposes and objectives of the psychopedagogy intervention. The implications, advantages and disadvantages of this model of practicum are discussed taking into account the guidelines of the European Higher Education Area.

Multi-Contact Grasp Interaction for Virtual Environments  

Directory of Open Access Journals (Sweden)

Full Text Available The grasping of virtual objects has been an active research field for several years. Solutions providing realistic grasping rely on special hardware or require time-consuming parameterizations. Therefore, we introduce a flexible grasping algorithm enabling grasping without computational complex physics. Objects can be grasped and manipulated with multiple fingers. In addition, multiple objects can be manipulated simultaneously with our approach. Through the usage of contact sensors the technique is easily configurable and versatile enough to be used in different scenarios.

InLab and Cerec Connect: virtual contacts in maximum intercuspation compared with original contacts--an in vitro study.  

UK PubMed Central (United Kingdom)

PURPOSE: The aim of this in-vitro study was to evaluate the accuracy of inLab and Cerec Connect software in simulating the maximum intercuspal contacts in comparison to the real situation on the respective gypsum casts. MATERIALS AND METHODS: Ten pairs of maxillary and mandibular casts were mounted in articulators in maximum intercuspal position. The contacts of the gypsum casts were marked and digital photographs of the mandibular casts were taken. Digital impressions of arches were made using two different software packages; inLab (Version 3.83) and Cerec Connect (Version 3.83) using the Cerec Acquisition Center. The intercuspal position of the teeth was captured by buccal images. Screenshots of the virtual casts showing the occlusal contacts were saved. The digital photographs of the contacts of the cast and the screenshots of the occlusal contacts were superimposed using an image processing program. The number of contacts of the virtual mandibular models that were identical with the contacts of the gypsum casts were determined and calculated as percentages in relation to the gypsum cast contacts, which were set as 100%. The null hypothesis tested was that the Cerec connect software delivers contacts that are closer to the real situation than contacts created with the inLab software. RESULTS: Cerec Connect showed a median percentage of 41.6% and Inlab a median percentage of 31.9%. The Wilcoxon test revealed statistically significant differences between the inLab software and Cerec Connect. Especially at the contra-lateral side of that side where the virtual buccal registration was done, the contacts showed the greatest deviations from the original. CONCLUSION: Cerec Connect more precisely virtually simulated the real contacts than did inLab when scanning full-arch dentitions.

The study about planetary gearbox virtual prototyping with nonlinear gear contact characteristics  

International Nuclear Information System (INIS)

[en] The virtual prototypes of gear transmission system built in most multi-body dynamic software have difficulties in describing the gear mesh characteristics. The gear mesh contact is modelled as rigid contact and this is not accurate for the gear mesh contact, which is elastic or flexible. The gear contact formula used in the multi-body dynamic software does not reveal the gear contact nonlinear stiffness characteristic. The model built with gear meshing contact is difficult to solve because of its time-consuming algorithm. In the paper a new method is put forward to build the virtual prototype of planetary gearbox system according to the nonlinear mesh stiffness and mesh phase obtained through FEM models. This new FEM method of gear mesh stiffness calculation is much more accurate than the common formulas. The gear mesh nonlinear stiffness of sun gear- pinion and pinion-ring gear of all the planetary gear sets in gearbox are obtained through MATALB code, which is used to read and plot the analyzing result data. The gear mesh phase differences between different pinions with suns or rings of different planetary gear set can be also obtained. With all these data modelled in simulink (or other software) and integrated with the multi-body dynamic planetary gearbox model and the gear meshing contact problem in multi-body gear models is solved easily and accurately. The interfaces for gear mesh stiffness and mesh phases are designed for multi-body dynamic model and simulink. The nonlinear planetary gear set prototyping models are integrated to become the whole planetary gear box model and the whole vehicle system model built in multi-body dynamic software can be integrated to simulate different duty conditions. At last high speed input is put into the nonlinear planetary transmission model and the different duty cases are simulated. The dynamic characteristics of different parts are obtained. The dynamic characteristic comparison between nonlinear and linear models is made. It solves the difficulty of gear contact simulation in multi-body dynamic model and provides a new method in gear mesh stiffness calculation, which exports simulationX (or other software) model of nonlinear gear stiffness to replace that in multi-body dynamic model and succeeds in integrating planetary gear transmission with other parts of the vehicle. According to the simulation results, the conclusion can be made that the nonlinear modelling method for planetary gearbox is reliable and practical. It can be used to evaluate vibration characteristic of planetary gear transmission with high speed input

Sociocultural approach to textbook  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this paper is to present an overview of textbook research at the Institute of psychology, intended to postulate socio-cultural approach to textbook. Shifting the textbook from classical pedagogical-psychological context into the broader and more inspiring cultural context, has led to the conceptualization of textbook as a cultural-supportive system of individual development. We consider firstly, the theoretical background of this conception, founded in Vygotskian idea of cultural mediation of development and then, its operationalization through the concept of cultural-supportive tools. The transfer from theory to practice is presented through the most important practical implications, such as defining the genre specificities of textbook and principles of educational design of textbooks. As a distinctive issue, we also consider the way this approach to textbook (theoretical articulation, analytical concepts, and practical implications) contributes to development of socio-cultural paradigm in psychology.

Moving the mandible to the retruded contact position for simulating the hinge movement in virtual three-dimensional orthognathic surgery by integrating the plaster models.  

Science.gov (United States)

The range of rotation of the mandible during virtual three-dimensional orthognathic surgery is small and may be similar to the hinge movement of the mandible. This current study offers a new method to move the mandible to the retruded contact position (RCP), a position of beginning hinge movement, during virtual three-dimensional orthognathic surgery. During this method, a three-dimensional skull model was reconstructed from the computed tomographic images in the Mimics software. Then the RCP in the patient could be obtained using Gothic arch tracer or swallowing method and was recorded using a wax plate, followed by transferring to plaster models. Subsequently, the plaster models in RCP were scanned using a dental surface scanner and imported into the Mimics software. Finally, we could move the mandible to the RCP based on the registration between the three-dimensional skull model and plaster model for simulating the hinge movement during virtual three-dimensional orthognathic surgery. This may be a small step forward for improving the accuracy of virtual three-dimensional orthognathic surgery. PMID:24036817

Sociocultural determinants of induced abortion  

International Nuclear Information System (INIS)

[en] Objective: To determine the frequency of induced abortion and identity the role of sociocultural factors contributing to termination of pregnancy and associated morbidity and mortality in hospital setting. Subjects and Methods: The patients who were admitted for induced abortion were interviewed in privacy. On condition of anonymity they were asked about the age, parity, family setup and relationships, with particular emphasis on sociocultural reasons and factors contributing to induction of abortion. Details of status of abortionist and methods used for termination of pregnancy, the resulting complications and their severity were recorded. Results: Out of total admissions, 57(2.35%) gave history of induced abortion. All women belonged to low socioeconomic class and 59.6% of them were illiterate. Forty-three (75.5%) of these women had never practiced concentration. Twenty-four (42%) were grandmultiparae and did not want more children. In 29 women (50.9%) the decision for abortion had been supported by the husband. In 25 (43.8%) abortion was carried out by Daiyan (traditional midwives). Serious complications like uterine perforation with or without bowel injury were encouraged in 25 (43.8%) of these women. During the study period illegally induced abortion accounted for 6 (10.5%) maternal deaths. Conclusion: Prevalence of poverty, illiteracy, grand multiparity and non-practice of contraception are strong determinants of induced abortion. (author)

Cognitive abilities, sociocultural background and academic achievement.  

UK PubMed Central (United Kingdom)

The influence of students' sociocultural background on academic achievement is a well established fact. Research also points out that sociocultural background is related to students' cognitive abilities and these have an effect on their academic achievement. However, the mediator role of cognitive abilities on the relationship between sociocultural background and academic achievement is less well known. A structural equation model that represents these relationships was tested in a sample (N= 728) of Portuguese junior high school students. Multigroup analysis of the model showed the importance of the cognitive ability mediation effect between sociocultural background and academic achievement in the 7th and 9th grades, but not in the 8th grade. This difference may be the result of the academic transition experienced in the 7th and 9th grades in the Portuguese educational system, which requires parents' higher involvement in school.

BASHKIR AND SIBERIAN TATAR EARLY SOCIO-CULTURAL COMMUNICATIONS  

Directory of Open Access Journals (Sweden)

Full Text Available The authors are investigating into insufficiently explored problem of Bashkir and Siberian Tatar early socio-cultural communications and ethnic interactions in the native historiography. The objective of the doing research is to clear up the base and the character of Bashkir and Siberian Tatar early socio-cultural communications and ethnic interactions. In the article is examined the character of contacts between Bashkir and each definite ethnographical group of Siberian Tatar. By the author’s opinion, these contacts were very tight and took their beginning in the early Middle Ages.The entrance of the Bashkir ethnic component into the structure of all the ethnographical groups Irtysh- Tobol Tatars was taking the place during the long historical time. But by the end of the XVIII century the fact of weakening of these connections is observed. Raising the frontier Orenburg and Uisk lines in order to protect the Russian settlements from the Bashkir attacks could be the reason for it. The investigation of this question could let find out the peculiarity of the modern ethnic processes on the territory of the South Ural and the West Siberia.

Sociocultural factors in Brazilian neuropsycholinguistic studies  

Directory of Open Access Journals (Sweden)

Full Text Available The history of Brazilian neuropsychology is traced at different neuropsycholinguistic stages with a focus on the importance of sociocultural factors. We first focus on language disorders, the sequelae of injuries in the left hemisphere, and neuropsychology restricted to the medical field in Europe, the United States, and Brazil. In the middle of the last century, attention to the interdisciplinary importance of studies on the right hemisphere began. Studies consequently emerged on the individual variability of brain function with both biological and cultural origins. Based on this approach, Brazilian studies on aphasic children and illiterate aphasic persons were disseminated internationally. In the 1970s, cognitive neuropsychology began in England, highlighting dysfunctions in reading and writing processes. The characteristics of writing systems within each language became relevant for the manifestations of acquired dyslexia. Brazilian studies showed deficits in Portuguese and Japanese writing caused by brain lesions. During this scientific journey, scientific societies and postgraduate programs in Brazil were created to facilitate exchanges and communication among young researchers. By the end of the last century and in the early 2000s, the growth of the neuropsychology of aging raised awareness of the complexity of sociocultural factors, not only on language research but also according to the level of education, frequency of reading and writing habits, school type, and interactions among these factors and biological factors, especially between the level of education and age. From this historical standpoint, we outline future directions and perspectives in the field of Brazilian neuropsychology.

The Subjectivity of the Translator and Socio-cultural Norms  

Directory of Open Access Journals (Sweden)

Full Text Available This thesis attempts to probe into the dialectical relationship between the subjectivity of the translator and socio-cultural norms. The socio-cultural norms inevitably regulate the translator’s translating activity, as acceptability of the translated text is the primary concern of most translators. However, this does not mean that the subjectivity of the translator is suppressed. The translator, in the wider socio-cultural context, assumes the subjective role in the translation process. The descriptive nature of these norms provides the great possibility for the translator to exert his subjectivity, which can be realized by the translator’s active manipulations on the source text. This point is well illustrated in the practical translation as the translator’s behaviour is constrained by a list of socio-cultural norms such as politics, ideology, ethics, morality and religion.

Virtual qubits, virtual temperatures, and the foundations of thermodynamics  

CERN Document Server

We argue that thermal machines can be understood from the perspective of `virtual qubits' at `virtual temperatures': The relevant way to view the two heat baths which drive a thermal machine is as a composite system. Virtual qubits are two-level subsystems of this composite, and their virtual temperatures can take on any value, positive or negative. Thermal machines act upon an external system by placing it in thermal contact with a well-selected range of virtual qubits and temperatures. We demonstrate these claims by studying the smallest thermal machines. We show further that this perspective provides a powerful way to view thermodynamics, by analysing a number of phenomena. This includes approaching Carnot efficiency (where we find that all machines do so essentially by becoming equivalent to the smallest thermal machines), entropy production in irreversible machines, and a way to view work in terms of negative temperature and population inversion. Moreover we introduce the idea of "genuine" thermal machin...

Virtual Laboratories and Virtual Worlds  

CERN Multimedia

Since we cannot put stars in a laboratory, astrophysicists had to wait till the invention of computers before becoming laboratory scientists. For half a century now, we have been conducting experiments in our virtual laboratories. However, we ourselves have remained behind the keyboard, with the screen of the monitor separating us from the world we are simulating. Recently, 3D on-line technology, developed first for games but now deployed in virtual worlds like Second Life, is beginning to make it possible for astrophysicists to enter their virtual labs themselves, in virtual form as avatars. This has several advantages, from new possibilities to explore the results of the simulations to a shared presence in a virtual lab with remote collaborators on different continents. I will report my experiences with the use of Qwaq Forums, a virtual world developed by a new company (see http://www.qwaq.com)

Virtual time  

Energy Technology Data Exchange (ETDEWEB)

Virtual time is a broad, new paradigm for organizing and synchronizing distributed systems, subsuming such heretofore distantly related problems as distributed discrete event simulation and distributed database concurrency control. It is an abstraction of real time in much the same way that virtual memory is an abstraction of real memory, and it reorganizes the concepts of concurrency and synchronization in a manner similar to the way virtual memory reorganized the subject of memory management. Virtual time systems can be implemented using the time warp mechanism, a distributed synchronization mechanism that is distinguished by its wholesale commitment to lookahead-rollback as its primary synchronization tool, but its implementation of rollback through antimessages, and by its global coordination through the concept of global virtual time. 14 references.

The sociocultural contexts of attempting suicide among women in Iran.  

Science.gov (United States)

In this study, we investigated the sociocultural contexts of suicide attempts among women in Iran. Fifty women who attempted suicide and were admitted to the two main hospitals in Isfahan in 2006 were interviewed. The main themes identified were family problems, marriage and love, social stigma, pressure of high expectations, and poverty. We observed significant sociocultural influence on attempting suicide among the Iranian women in this study. Based on our findings we conclude that the women in the study were affected by social changes and the interplay between traditional and modern values and attitudes. Understanding sociocultural aspects of suicide in Iran is critical in providing effective and culturally sensitive suicide prevention and care programs. PMID:20677036

Antimicrobial resistance gene distribution: a socioeconomic and sociocultural perspective  

Directory of Open Access Journals (Sweden)

Full Text Available The appearance of resistance to many first-line antimicrobial agents presents a critical challenge to the successful treatment of bacterial infections. Antimicrobial resistant bacteria and resistance genes are globally distributed, but significant variations in prevalence have been observed in different geographical regions. This article discusses possible relationships between socioeconomic and sociocultural factors and regional differences in the prevalence of antibiotic-resistant bacteria and their associated resistance genes. Findings indicate that the few studies that have been conducted to understand relationships between socioeconomic and sociocultural factors and antimicrobial resistance have focused on patterns of phenotypic antibiotic resistance. Yet, a critical need exists for molecular studies of human influences on bacterial resistance and adaptation. We propose that the results of these studies, coupled with well-coordinated culturally appropriate interventions that address specific socioeconomic and sociocultural needs may be necessary to reduce the scourge of antimicrobial resistance in both developing and developed countries.

Sources of perceived sociocultural pressure on physical self-concept.  

UK PubMed Central (United Kingdom)

BACKGROUND: The aim of this study is to analyze the four-factor structure (advertising, information, family environment and friendship setting) of the Cuestionario de Influjos Socioculturales sobre el Autoconcepto Físico (CIAF) [Sociocultural Influences on Physical Self-concept Questionnaire] and its invariance in relation to sex, age and physical activity. METHOD: Participants were 579 students (339 men and 240 women) aged between 12 and 23, divided into three groups (137 under 14 years, 338 aged between 15 and 18 and 104 over 18 years). All completed the CIAF. RESULTS: Both the confirmatory factor analyses and the factor invariance tests support the four-factor structure of the CIAF and, therefore, the identification of four different types of sociocultural perceived influence. CONCLUSIONS: These results allow us to apply the abundant data found by previous studies on sociocultural pressure on body image to our understanding of physical self-concept.

Contact lens correction of presbyopia.  

UK PubMed Central (United Kingdom)

The ageing population highlights the need to provide effective optical solutions for presbyopic contact lens wearers. However, data gathered from annual contact lens fitting surveys demonstrate that fewer than 40% of contact lens wearers over 45 years of age (virtually all of whom can be presumed to suffer a partial or complete loss of accommodation) are prescribed a presbyopic correction. Furthermore, monovision is prescribed as frequently as multifocal lenses. These observations suggest that an optimal solution to the contact lens correction of presbyopia remains elusive.

Aids, drogas, riscos e significados: uma construção sociocultural AIDS, drugs, risks and meanings: a sociocultural construction  

Directory of Open Access Journals (Sweden)

Full Text Available O artigo analisa discursos sobre o risco do HIV/Aids e das drogas, extraídos de duas pesquisas qualitativas desenvolvidas entre jovens de escolas públicas e jovens participantes em programas e serviços sociais públicos. Os dados provieram de grupos focais, oficina e resposta escrita a uma questão aberta; e questionário com questões fechadas e abertas. O texto se baseia em dois eixos de análise presentes no caso da aids e das drogas. O primeiro se relaciona à projeção do risco para um território distante estabelecido pela figura do "outro". O segundo se refere à busca do prazer trazido pelo sexo e pelas drogas, prazer constituído pela sensação de vertigem, de êxtase, de perda dos sentidos, componente oposto à racionalidade esperada pelo discurso preventivo. A compreensão sociocultural do risco nos levou a considerar que, embora cientes do discurso preventivo relacionado aos efeitos negativos das drogas e do HIV/Aids, os jovens o incorporam de forma particular, na qual aparecem inconsistências, ambivalências e ambigüidades. Concluímos que a linguagem do risco para os jovens é diferente daquela presente na área da saúde. Os riscos são concebidos e controlados em meio a diferenças culturais e não reduzidos à probabilidade de ocorrência de um evento negativo, como tratado pela linguagem racional moderna.The article analyzes the discourse about the risk represented by HIV/Aids and drugs, found in two qualitative researches carried out with youngsters from public schools and from public social services and programs. The data came, for the first research, from focus groups, workshops and a written answer to an open question; and for the second one, a questionnaire with close and open questions. This text is based on two analysis axes which occur in both cases, aids and drugs. The first one is related to the projection of the risk to a distant territory established by the figure of the "other". The second one is related to the search for pleasure provided by sex and drugs, pleasure which derives from dizziness, ecstasy, senses'loss, opposed to the rationality expected by the preventive discourse. The sociocultural comprehension of the risks led us to consider that, in spite of the knowledge about the preventive discourse of the negative effects related to aids and drugs, this is done with inconsistency, ambivalence and ambiguities. It is concluded that the language of the risk for the youngsters is different from the one presented in the health area. These risks are conceived and controlled within the framework of cultural differences, not being reduced to the probability of a negative event, as in the modern rational language.

Virtual Tower  

Energy Technology Data Exchange (ETDEWEB)

The primary responsibility of an intrusion detection system (IDS) operator is to monitor the system, assess alarms, and summon and coordinate the response team when a threat is acknowledged. The tools currently provided to the operator are somewhat limited: monitors must be switched, keystrokes must be entered to call up intrusion sensor data, and communication with the response force must be maintained. The Virtual tower is an operator interface assembled from low-cost commercial-off-the-shelf hardware and software; it enables large amounts of data to be displayed in a virtual manner that provides instant recognition for the operator and increases assessment accuracy in alarm annunciator and control systems. This is accomplished by correlating and fusing the data into a 360-degree visual representation that employs color, auxiliary attributes, video, and directional audio to prompt the operator. The Virtual Tower would be a valuable low-cost enhancement to existing systems.

Strategy and methodology for the sociocultural reform of education  

Directory of Open Access Journals (Sweden)

Full Text Available This chapter explains the strategy for the sociocultural reform of education as a socialization institution that plays a key role in the focused development of value systems, standards, paradigms, and behavioral patterns in the population of Russia. The author reveals the role education plays in modeling such phenomena of social development as the social consolidation of society, the civil identity of representatives of various social groups and national cultures, the encouragement of social confidence, the successful socialization of oncoming generations, and the social stratification of the population of Russia. This chapter also considers the benefits of the sociocultural reform of education as a growth driver for the competitive strength of the individual, the society, and the state and for the further design of long-term programs for the social and economic development of Russia, including the federal education-development program.

Virtual Autopsy  

Science.gov (United States)

Designed with medical students in mind, Leicester (England) University's Virtual Autopsy site takes the student on a virtual tour of seven autopsies. Several options allow for efficient navigation of the site: Cause of Death is a self-assessment quiz students may take after "performing" each autopsy; Return to History takes the user back to the beginning of each case; and Choose another Case lets the user move between the seven cases. Each case contains nearly a dozen detailed color images of certain key parts (including tissues) of the human anatomy--lung, body, heart, head--with hyperlinks to further information. By clicking on the dictionary icon, for instance, a student links to a pop-up page with detailed descriptions of that particular condition. Aspiring pathologists are sure to find this worthwhile, and the absence of gruesome images makes it a good learning site for many budding medical scientists as well.

Regulation of positive and negative emotion: effects of sociocultural context.  

UK PubMed Central (United Kingdom)

Previous research has demonstrated that the use of emotion regulation strategies can vary by sociocultural context. In a previous study, we reported changes in the use of two different emotion regulation strategies at an annual alternative cultural event, Burning Man (McRae et al., 2011). In this sociocultural context, as compared to typically at home, participants reported less use of expressive suppression (a strategy generally associated with maladaptive outcomes), and greater use of cognitive reappraisal (a strategy generally associated with adaptive outcomes). What remained unclear was whether these changes in self-reported emotion regulation strategy use were characterized by changes in the regulation of positive emotion, negative emotion, or both. We addressed this issue in the current study by asking Burning Man participants separate questions about positive and negative emotion. Using multiple datasets, we replicated our previous findings, and found that the decreased use of suppression is primarily driven by reports of decreased suppression of positive emotion at Burning Man. By contrast, the increased use of reappraisal is not characterized by differential reappraisal of positive and negative emotion at Burning Man. Moreover, we observed novel individual differences in the magnitude of these effects. The contextual changes in self-reported suppression that we observe are strongest for men and younger participants. For those who had previously attended Burning Man, we observed lower levels of self-reported suppression in both sociocultural contexts: Burning Man and typically at home. These findings have implications for understanding the ways in which certain sociocultural contexts may decrease suppression, and possibly minimize its associated maladaptive effects.

Estrategias de aculturación y adaptación psicológica y sociocultural de estudiantes extranjeros en la Argentina/ Acculturation strategies and psychological and sociocultural adaptation of foreign students in Argentina

Full Text Available Abstract in spanish Sobre la base del modelo de Berry se diseñó un estudio que tenía como objetivo analizar las estrategias aculturativas empleadas por un grupo de estudiantes extranjeros que habían migrado para realizar estudios universitarios en la Argentina. Se analizó el grado de éxito alcanzado en la implementación de dichas estrategias analizando la adaptación psicológica, la sociocultural, la académica, la satisfacción vital y la discriminación percibida. Se tomó en cuent (more) a la perspectiva del migrante y la de los miembros de la cultura huésped. Participaron del estudio dos muestras de estudiantes universitarios (125 estudiantes extranjeros de diferentes carreras universitarias y 121estudiantes universitarios argentinos). Los instrumentos utilizados fueron los siguientes: las formas real e ideal de la Encuesta de Estrategias Aculturativas de Berry (1997), una escala de discriminación percibida y para examinar las medidas de adaptación, se administraron escalas de adaptación sociocultural y de adaptación académica diseñadas ad-hoc y la Escala de Satisfacción con la Vida (Diener, Emmons, Larsen & Griffin, 1985). Los resultados señalan que la estrategia preferida es la integración y la menos utilizada, la de marginalización. Tanto la percepción del migrante como la del estudiante huésped coinciden con respecto al uso de la estrategia aculturativa preferida, coincidiendo las percepciones tanto del propio sujeto en proceso de aculturación como la de los miembros de la cultura receptora. La integración es la estrategia que trae mejores resultados adaptativos. Aquellos que optaron por el estilo integrativo, eran los migrantes que percibían mayor satisfacción con la vida y un mejor ajuste a la vida académica en general. Abstract in english At present the number of foreign university student is one of the largest in modern history. It has been characterized as those who reside voluntarily and temporarily abroad in order to participate in educational exchange with the intention of returning to their country once they have achieved the purpose of their trip. These kinds of student have been classified as sojourners (temporary residents) and they are people who migrate from one cultural context for a relatively (more) long time (6 months to 5 years). In the last decade Argentina start hosting a large amount of foreign university students, attracted by the language, the favorable economic conditions and the prestige of universities in Latin America. University students have to deal with a psychological phenomenon called acculturation and it is the process of psychological and cultural change resulting from intercultural contact. Adaptation to this event can be either psychological or cultural. The psychological is related to the well-being experienced as a result of cultural contact. Cultural adaptation involves the implementation of social skills needed to function effectively within a complex cultural environment. Based on acculturation Berry´s model a study was designed to test the acculturative strategies applied by a group of foreign students who had migrated to carry on university studies in Argentina. Berry propose two separate dimensions: (1) immigrants feel their cultural identity and customs as valuable enough to keep them in the host society (maintenance) and (2) relationships with other people or groups in society are truly valuable to identified and encouraged (participation). These dimensions lead to four acculturation strategies. (a) Integration: the migrant try to maintain their cultural heritage and also maintains contact with the dominant cultural group. (b) Assimilation: the individual does not retain their native culture and attempts to maintain contact only with dominant culture members. (c) Marginalization: occurs when the migrant has no interest or ability to pursue their native culture and it is unlikely to come into contact with the host culture. (d) Separation: this occurs when the migrant is able to maintain their original culture but avoid or

COLONOSCOPIA VIRTUAL  

Directory of Open Access Journals (Sweden)

Full Text Available Desde la primera publicación sobre colonoscopía virtual o colonografía por tomografía computada (TC) esta técnica ha tenido un explosivo crecimiento especialmente dado por el desarrollo en el hardware, específicamente por la introducción de la TC multicorte que ha permitido obtener mejores imágenes gracias a la mayor velocidad que ha obviado los artefactos dados por el movimiento respiratorio y el peristaltismo intestinal. Otro factor importante en su desarrollo ha sido el gran avance en los programas computacionales (software) que han automatizado la técnica obteniendo recons-trucciones 3D de mejor calidad y en menor tiempo. El notable desarrollo tecnológico sumado a la estandarización de la técnica y la mayor experiencia lograda en diferentes centros ha hecho que en la actualidad la sensibilidad y especificidad de la colonografía sobrepasen el 85 y 95% para los pólipos menores y mayores de 1 cm, respectivamente. Todo esto, sumado a la estandarización de la técnica ha llevado a posicionarla como una alternativa válida y en estrecha competencia con la fibrocolonoscopía en la pesquisa de los pólipos de colonSince the first report in 1994 virtual colonoscopy or CT colonography has had an explosive development due to the improvement in hardware and software. The multidetector CT has allowed faster studies with better images due to better multiplanar reconstructions and its speed avoiding the artifact of the breathing or bowel peristalsis. The new software has allowed to obtain better 3D images and faster reconstruction with shorter interpretation. This development, the use of standarized protocol plus the experience of trained radiologists have obtained sensitivity and specificity over 85% and 95% in polyps smaller and larger than 10 mm respectively. These results and the lower price of virtual colonoscopy in the United States compared with fibrocolonoscopy has done this technique a real alternative for the screening of colorectal cancer side by side with fibrocolonoscopy

The sociocultural context of condom use within marriage in rural Lebanon.  

UK PubMed Central (United Kingdom)

Prevalence rates for condom use are low across the Middle East despite limited alternate contraceptive options and growing awareness of sexually transmitted diseases (STDs) and HIV/AIDS. Virtually no research exists to explain this situation and to guide policy development or effective interventions. An analysis of 25 focus-group discussions with married women and men, interviews with service providers, and a survey of 589 women of childbearing age in a rural district of southern Lebanon reveal that a broad and complex set of sociocultural factors influence condom use. In the study area, 7 percent of married women currently use condoms, 24 percent reported ever use, and inconsistent use is common. Condoms are preferred primarily for their lack of physiological side effects. Five factors were found to impede method adoption and sustained use. These include various encumbering beliefs, reduced sexual pleasure, adverse experiences, gender-related fears and tensions, and a residual social stigma attached to condoms. Several strategies are suggested to increase and improve condom use. These issues will assume greater importance as fertility declines further in the region, demand for contraception continues to increase, and STDs and HIV/AIDS become more deeply rooted, as has occurred in other parts of the world.

Virtual Texturing  

CERN Multimedia

In this thesis a rendering system and an accompanying tool chain for Virtual Texturing is presented. Our tools allow to automatically retexture existing geometry in order to apply unique texturing on each face. Furthermore we investigate several techniques that try to minimize visual artifacts in the case that only a small amount of pages can be streamed per frame. We analyze the influence of different heuristics that are responsible for the page selection. Alongside these results we present a measurement method to allow the comparison of our heuristics.

Examination of a sociocultural model of excessive exercise among male and female adolescents.  

Science.gov (United States)

There is substantial evidence that sociocultural pressures and body image disturbances can lead to disordered eating, yet few studies have examined their impact on excessive exercise. The study adapted a sociocultural model for disordered eating to predict excessive exercise using data from boys and girls in early adolescence (N=421). Perceived sociocultural pressures to lose weight and build muscle, body image disturbance and appearance investment were associated with a compulsive need to exercise. Adolescents' investment in appearance and body image disturbance fully mediated the relationship between sociocultural pressures and a compulsive need for exercise. There was no support for the meditational model in predicting adolescents' frequency or duration of exercise. Results support the sociocultural model as an explanatory model for excessive exercise, but suggest appearance investment and body image disturbance are important mediators of sociocultural pressures.

Virtual qubits, virtual temperatures, and the foundations of thermodynamics.  

UK PubMed Central (United Kingdom)

We argue that thermal machines can be understood from the perspective of "virtual qubits" at "virtual temperatures": The relevant way to view the two heat baths which drive a thermal machine is as a composite system. Virtual qubits are two-level subsystems of this composite, and their virtual temperatures can take on any value, positive or negative. Thermal machines act upon an external system by placing it in thermal contact with a well-selected range of virtual qubits and temperatures. We demonstrate these claims by studying the smallest thermal machines. We show further that this perspective provides a powerful way to view thermodynamics, by analyzing a number of phenomena. This includes approaching Carnot efficiency (where we find that all machines do so essentially by becoming equivalent to the smallest thermal machines), entropy production in irreversible machines, and a way to view work in terms of negative temperature and population inversion. Moreover we introduce the idea of "genuine" thermal machines and are led to considering the concept of "strength" of work.

THE IMPACT OF TOURISM ON THE SOCIOCULTURAL STRUCTURE OF CYPRUS  

Directory of Open Access Journals (Sweden)

Full Text Available This paper is based on evaluating tourism development in Cyprus, a European nation, and its impacts on the socio-cultural structure of the island. The principal concern of this research is aid in sustaining the resource base on which the tourism development in Cyprus depends on. The paper concludes that in spite of all the negative and positive impacts of tourism on Cyprus it is not yet clear whether the benefits outweigh the costs. The reason for this uncertainty is that most of the research is done on an estimate as there is no empirical data available as yet to support either side of the equation.

Human tooth bank: sociocultural profile of a group of donors  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To survey the sociocultural profile of a specific group of individuals who donated teeth to the Human Tooth Bank of Positivo University, Curitiba, Paraná, Brazil. Methods: The research consisted of a questionnaire containing the following information about: Patient’s age, sex, occupation, education, reason for tooth loss and intention to replace the missing tooth by means of prosthesis or implant. The questionnaire was filled out by 50 patients after having the extraction procedure performed and donating the dental organ. The data were compiled and analyzed by means of descriptive and multivariate statistics. Results: The sociocultural profile of the donor was basically composed of individuals in the age group between 30 and 50 years, with educational level ranging from zero to nine or more years of formal schooling. Caries disease was the most frequent reason for tooth loss (36%), followed by periodontal disease (34%). Of the donors analyzed, more than half did not intend to replace the tooth. Furthermore, according to the multivariate analysis, the most relevant factors for assessing the profile of donors were the variables age, orthodontic indication, caries and periodontal disease. Conclusion: This information was shown to be relevant for structuring the oral health care services, as well as in the strategy for obtaining teeth from the Public Health Units.

Socio-cultural acceptability of cadaver Transplantation in Iran  

Directory of Open Access Journals (Sweden)

Full Text Available Organ transplantation is known to be a new and innovative treatment for patients with progressive organ failures. The present study investigates the current status of transplantation from cadaver along with its socio-cultural acceptability in Iran. The present study is a descriptive research in a systematic review method. Here, by investigating previously conducted researches in Iran during the period 2002-2010, the status of transplantation from cadaver and its socio-cultural acceptability in Iran has been investigated. To collect the data, the access to Iranmedex website, the premier medical data center in Iran, was made possible using the related keywords. The obtained data indicate whereas there is an increase in the number of organ donations from cadaver, it is still low in comparison to other countries. The lack of consent from families of brain-dead patients is a major hurdle on the way of organ transplantation in Iran. In the cases of willingness to donate organs, the major effective factors were the deceased’s religious beliefs and prior tendency. In 66% of the cases, the donors’ families deemed organ donation phenomenon effective in alleviating the sorrow after the death of their beloved ones. The number of organ donation from cadaver in Iran is low contrary to other countries. It seems that general instructions to raise the knowledge on the subject and lay the foundation to increase the tendency towards posthumous organ donation are necessary.

Customized Asthma Control Test with reflection on sociocultural differences.  

UK PubMed Central (United Kingdom)

We evaluated the utility and feasibility of customizing Asthma Control Test (ACT) items to generate a Korean Asthma Control Test (KACT) specific for Korean patients. We surveyed 392 asthma patients with 19 items, selected to reflect the Korean sociocultural context. Guideline ratings were integrated with the evaluations of specialists (i.e., using both guide base rating together with specialist's rating), and items with the greatest discriminating validity were identified. Stepwise regression methods were used to select items. KACT scale scores showed significant differences between the asthma control ratings generated by integrating ratings (r=0.77, P<0.001), by specialist's evaluations (r=0.54, P<0.001), or by FEV(1) percent predicted (r=0.39, P<0.001). Specialist's and guideline ratings detected 56% and 48.6% of patients with well-controlled asthma, respectively. However, the integrated ratings indicated that only 34.3% of the patients in the test sample were well controlled. The overall agreement between KACT and the integrated rating ranged from 45% to 78%, depending on the cut-off points used. It is possible to formulate a valid, useful country-specific diagnostic tool for the assessment of asthma patients based on the original ACT that reflect differences in sociocultural context.

Artificial donor insemination in Yaounde: some socio-cultural considerations.  

UK PubMed Central (United Kingdom)

Infertility affects about 14% of the population in Cameroon. The majority of those affected are between 26-30 years old. Between 40-50% of all cases of infertility are associated with male failure, and azoospermia is implicated in 14.4% of the cases. There is thus an indication for assisted reproduction among this category of infertile couples particularly artificial insemination by donor (A.I.D.). A comparative study on fertile and infertile couples' perception of A.I.D. revealed that knowledge of A.I.D. is low, 35.30% of infertile respondents were aware of the procedure via à vis 30.6% of their fertile counterparts. Nonetheless 49% of infertile respondents accepted A.I.D. in principle compared to 37.75% of their fertile counterparts. Despite the high value respondents placed on having children and the strong desire by infertile couples to have their reproductive potentials fulfilled, only 19.6% of infertile respondents and 42.87% of their fertile counterparts respectively, would actually practice A.I.D. if the need arose. There are indications that respondents did not perceive A.I.D. as an acceptable solution to infertility. Evidently, the possible influence of socio-cultural barriers to A.I.D. as well as perceived socio-cultural alternatives which may be more acceptable to infertile couples than a technically assisted form of reproduction, have been overlooked.

A socio-cultural model of Judean ethnicity: A proposal  

Directory of Open Access Journals (Sweden)

Full Text Available This article focuses on the matter of Judean (“Jewish”) ethnic identity during the first century CE. New Testament scholarship lacks an overall interpretive framework by which Judean identity can be understood. Appreciation of what informed the entire process of Judean ethnic identity formation in the first century, or at any period for that matter, is lacking. This lack of interpretive framework is rather acute in scholarship on the historical Jesus, where the issue of Judeanness (“Jewishness”) is most strongly debated. A Socio-Cultural Model of Judean Ethnicity is developed, as being a synthesis of (1) Sanders’ notion of covenantal nomism, but reappropriated to serve as an ethnic descriptor, (2) Berger and Luckmann’s theories on the sociology of knowledge, (3) Dunn’s “four pillars of Second Temple ‘Judaism’” and his “new perspec-tive” on Paul, (4) cultural anthropology in the form of modern ethnicity theory, and lastly, (5) Duling’s Socio-Cultural Model of Ethnicity. The proposed model is termed covenantal nomism. It is a pictorial representation of the Judean “symbolic universe” which, as an ethnic identity, is proposed to be essentially primordialist.

Humorous Interpretations of Abbreviations as a Socio-Cultural Phenomenon  

Directory of Open Access Journals (Sweden)

Full Text Available The article discusses the nature of abbreviation jokes, the possibleformulation principles, relations to humour and slang and the way their interpretation depends on the socio-cultural context. The abbreviated riddle corpus, (ca 3,000 texts of about 330 types) stored in the Folklore Archives of the Estonian Literary Museum, constitutes the source material for the study. The material has been systematised and presented in the database Eesti lühendmõistatused or Estonian Abbreviation Riddles (Voolaid 2004). The database provides a fine overview of alternative folkloric interpretations of abbreviationsand acronyms in different periods and allows us to diachronically observe and describe the transformation of the genre in the socio-cultural context. The article introduces the possible ways of systematisation and formulation principles of the alternative interpretations of Estonian abbreviations (abbreviation parodies) bordering folklore and language. Folklorists have approached the phenomenon as a subgenre of riddles: the question part consists of a conventional abbreviation, whereas the explanation provided in the answer part is radically different from the conventional one; it is witty and humorous, often with a political or sexual undertone. A single abbreviation may produce several alternative interpretations, including the conventional and the folkloric explanation. Alternative (often witty) interpretation of abbreviations can be consideredan important source of the slang lexicon of group languages (e.g., exclusive subcultures, professional parlance) or secret language.

Long Range Contacts in Overlay  

UK PubMed Central (United Kingdom)

A fundamental aspect in the design of overlay networks is the path length/node degreetrade-o#. Previous research has shown that it is possible to achieve logarithmic path lengthsfor logarithmic or even constant node degree. While nearby contacts, with nodes that haveclose identifiers, ensure a connected lattice of nodes, short path lengths demand for the useof long range contacts. In this respect, previous work exhibits limitations in scenarios wherenode distribution is unbalanced: either short path length properties do not hold or may requirenode degree and/or signaling to grow with respect to the virtual identification spaceinstead of the number of nodes (which is usually several order of magnitudes smaller).

Socio-Cultural Approaches to Tourism: A Research on the “Tourist” Notion of Young Turkish People  

Directory of Open Access Journals (Sweden)

Full Text Available Significance of tourism sector in Turkey is constantly expanding. Correspondingly the importance of the economic and socio-cultural impact of tourism also continues to develop. Because tourism draws tourists get into closer contact with the locals it has positive and negative effects on the destination. In general the aim of tourists is satisfying their expectations at the maximum degree during their stay. On the other side locals who live and work in the destination region have a primary role in welcoming them and satisfying the tourists’ needs and expectation. Turkish society is particularly well known for many generations as being very hospitable. Current research aims to reveal whether the young Turkish people sustain traditional “Turkish Hospitality” and to see their thoughts about tourists. The field research has been conducted on students of a foundation university located in Izmir and these young people’s point of view on tourists has been investigated by face to face interviews. It has been concluded that there is a weakening trend, nevertheless the notion of hospitality remains.

Virtual PCR  

Energy Technology Data Exchange (ETDEWEB)

The polymerase chain reaction (PCR) stands among the keystone technologies for analysis of biological sequence data. PCR is used to amplify DNA, to generate many copies from as little as a single template. This is essential, for example, in processing forensic DNA samples, pathogen detection in clinical or biothreat surveillance applications, and medical genotyping for diagnosis and treatment of disease. It is used in virtually every laboratory doing molecular, cellular, genetic, ecologic, forensic, or medical research. Despite its ubiquity, we lack the precise predictive capability that would enable detailed optimization of PCR reaction dynamics. In this LDRD, we proposed to develop Virtual PCR (VPCR) software, a computational method to model the kinetic, thermodynamic, and biological processes of PCR reactions. Given a successful completion, these tools will allow us to predict both the sequences and concentrations of all species that are amplified during PCR. The ability to answer the following questions will allow us both to optimize the PCR process and interpret the PCR results: What products are amplified when sequence mixtures are present, containing multiple, closely related targets and multiplexed primers, which may hybridize with sequence mismatches? What are the effects of time, temperature, and DNA concentrations on the concentrations of products? A better understanding of these issues will improve the design and interpretation of PCR reactions. The status of the VPCR project after 1.5 years of funding is consistent with the goals of the overall project which was scoped for 3 years of funding. At half way through the projected timeline of the project we have an early beta version of the VPCR code. We have begun investigating means to improve the robustness of the code, performed preliminary experiments to test the code and begun drafting manuscripts for publication. Although an experimental protocol for testing the code was developed, the preliminary experiments were tainted by contaminated products received from the manufacturer. Much knowledge has been gained in the development of the code thus far, but without final debugging, increasing its robustness and verifying it against experimental results, the papers which we have drafted to share our findings still require the final data necessary for publication. The following sections summarize our final progress on VPCR as it stands after 1.5 years of effort on an ambitious project scoped for a 3 year period. We have additional details of the methods than are provided here, but would like to have legal protection in place before releasing them. The result of this project, a suite of programs that predict PCR products as a function of reaction conditions and sequences, will be used to address outstanding questions in pathogen detection and forensics at LLNL. VPCR should enable scientists to optimize PCR protocols in terms of time, temperature, ion concentration, and primer sequences and concentrations, and to estimate products and error rates in advance of performing experiments. Our proposed capabilities are well ahead of all currently available technologies, which do not model non-equilibrium kinetics, polymerase extension, or predict multiple or undesired PCR products. We are currently seeking DHS funding to complete the project, at which time licensing opportunities will be explored, an updated patent application will be prepared, and a publication will be submitted. A provisional and a full patent application have already been filed (1).

Sociocultural input facilitates children's developing understanding of extraordinary minds.  

UK PubMed Central (United Kingdom)

Three- to 5-year-old (N = 61) religiously schooled preschoolers received theory-of-mind (ToM) tasks about the mental states of ordinary humans and agents with exceptional perceptual or mental capacities. Consistent with an anthropomorphism hypothesis, children beginning to appreciate limitations of human minds (e.g., ignorance) attributed those limits to God. Only 5-year-olds differentiated between humans' fallible minds and God's less fallible mind. Unlike secularly schooled children, religiously schooled 4-year-olds did appreciate another agent's less fallible mental abilities when instructed and reminded about those abilities. Among children who understood ordinary humans' mental fallibilities, knowledge of God predicted attributions of correct epistemic states to extraordinary agents. Results suggest that, at a certain point in ToM development, sociocultural input can facilitate an appreciation for extraordinary minds.

Sociocultural settings influence the emergence of prelinguistic deictic gestures.  

Science.gov (United States)

Daily activities of forty-eight 8- to 15-month-olds and their interlocutors were observed to test for the presence and frequency of triadic joint actions and deictic gestures across three different cultures: Yucatec-Mayans (Mexico), Dutch (Netherlands), and Shanghai-Chinese (China). The amount of joint action and deictic gestures to which infants were exposed differed systematically across settings, allowing testing for the role of social-interactional input in the ontogeny of prelinguistic gestures. Infants gestured more and at an earlier age depending on the amount of joint action and gestures infants were exposed to, revealing early prelinguistic sociocultural differences. The study shows that the emergence of basic prelinguistic gestures is socially mediated, suggesting that others' actions structure the ontogeny of human communication from early on. PMID:23252681

Exploring complex sociocultural situations through soft operational research  

Directory of Open Access Journals (Sweden)

Full Text Available A paradigm can be thought of as a living commodity system, carried by a self-organising group. The commodity is often "practical knowledge", and the paradigm maintains a life cycle that begins with commodity gestation, leading to commodity depreciation through death or transformation. During its normal life processes paradigm grow their commodities incrementally, but the growth processes become bounded through the very conceptualisations that made them successful, limiting their pragmatic capabilities. Paradigms have not only normal lives, but also post-normal lives. In the current cultural environment normal paradigmatic life processes are said to be hard, while post-normal ones are said to be soft, with this change being facilitated through epistemological shift. An illustration of a new framework called sociohistory is shown to be a soft OR approach. Its purpose is to describe, explore and evaluate complex sociocultural problem situations, with the potential to create intervention strategies that might be able to improve them.

UNINTELLIGIBILITY OF TOKENS IN VIRTUAL TOURISM  

Directory of Open Access Journals (Sweden)

Full Text Available Tourism has been studied in three historical contexts: Pre-modern era, which has had a religious purpose and a narrative genre-based research approach; Modern era, in which tourism becomes an industry, with emphasis on the same role in a surveybased research; and post-modern era, with emphasis on socio-cultural, IT-basedcontexts and interdisciplinary role of scientific approach. E-travel implies locomotion in cyberspace and its technology has initially been associated with the computer reservations system (CRS) of the airlines industry, but now it is used more inclusively, incorporating the broader tourism sector as well as its subset. While travel technology includes the computer reservations system, it alsorepresents a much broader range of applications, in fact increasingly so. Travel technology includes virtual tourism in the form of virtual tour applications of Information Technology (IT), or Information and Communications Technology (ICT), in travel, tourism and hospitality industry. E-tourism, as an interdisciplinary field of study incorporating management, IT/ICT, sociolinguistics… has recently been used as a vehicle to take tourists to far distance places and to provide them a chance to enjoy visiting historical sites via cybernetic links, descriptive statements or panoramic virtual photos. The present study has shed some light on the efficacy of such virtual tourism in conveying culture-specific elements, labelled tokens. To that end, a website- Maryam virtual tourism- has been designed to introduce the aforementioned aspects of Shiraz, Iran, in the site with all the possible wares used to that end. A survey was performed on certain candidates, basically specialists in the field and outstanding tourists, familiar with cultural dynamics of Shiraz. They have been identified and put into the databases, after beingconsulted. The technique has been on line questionnaire as well as far distances textbased interviews. Data elicitation has taken the researcher a six-month time. Results are statistically significant enough to prove the hypothesis that tokens cannot be simply rendered via the present cybernetic techniques interactively in a personalizedweb designs, software and web-based instrumental effects such as 3D scenes, or simulation platforms like WebGIS. This paper points to the fact that there is no mature platform for introducing cultural token elements via virtual tour system, at present. Therefore, it is necessary to combine the application of cyber glasses, a workable definition of ontologism in semantic web designs & WebGIS withinterdisciplinary tokens-familiar technology to develop a specific virtual simulation platform for tourism with an aim of making cultural token elements intelligible.

Sociocultural contexts of attempting suicide among Iranian youth: a qualitative study.  

UK PubMed Central (United Kingdom)

This paper seeks to illuminate the sociocultural contexts of attempting suicide among Iranian youth. A qualitative approach was employed to uncover the social and cultural dimensions of attempting suicide. In-depth interviews were conducted with 25 participants aged 14-17 years who attempted suicide and were admitted to 2 of the hospitals in Isfahan. A thematic analysis approach was employed. The main themes identified were failure in love, family problems, study, pressure of high expectations and poverty. The findings suggest significant sociocultural influence on attempting suicide in the Islamic Republic of Iran. Exploring sociocultural aspects of suicide is critical in providing effective and culturally-sensitive suicide prevention and care programmes.

Comparing sociocultural features of cholera in three endemic African settings.  

UK PubMed Central (United Kingdom)

BACKGROUND: Cholera mainly affects developing countries where safe water supply and sanitation infrastructure are often rudimentary. Sub-Saharan Africa is a cholera hotspot. Effective cholera control requires not only a professional assessment, but also consideration of community-based priorities. The present work compares local sociocultural features of endemic cholera in urban and rural sites from three field studies in southeastern Democratic Republic of Congo (SE-DRC), western Kenya and Zanzibar. METHODS: A vignette-based semistructured interview was used in 2008 in Zanzibar to study sociocultural features of cholera-related illness among 356 men and women from urban and rural communities. Similar cross-sectional surveys were performed in western Kenya (n = 379) and in SE-DRC (n = 360) in 2010. Systematic comparison across all settings considered the following domains: illness identification; perceived seriousness, potential fatality and past household episodes; illness-related experience; meaning; knowledge of prevention; help-seeking behavior; and perceived vulnerability. RESULTS: Cholera is well known in all three settings and is understood to have a significant impact on people's lives. Its social impact was mainly characterized by financial concerns. Problems with unsafe water, sanitation and dirty environments were the most common perceived causes across settings; nonetheless, non-biomedical explanations were widespread in rural areas of SE-DRC and Zanzibar. Safe food and water and vaccines were prioritized for prevention in SE-DRC. Safe water was prioritized in western Kenya along with sanitation and health education. The latter two were also prioritized in Zanzibar. Use of oral rehydration solutions and rehydration was a top priority everywhere; healthcare facilities were universally reported as a primary source of help. Respondents in SE-DRC and Zanzibar reported cholera as affecting almost everybody without differentiating much for gender, age and class. In contrast, in western Kenya, gender differentiation was pronounced, and children and the poor were regarded as most vulnerable to cholera. CONCLUSIONS: This comprehensive review identified common and distinctive features of local understandings of cholera. Classical treatment (that is, rehydration) was highlighted as a priority for control in the three African study settings and is likely to be identified in the region beyond. Findings indicate the value of insight from community studies to guide local program planning for cholera control and elimination.

Biquandles for Virtual Knots  

CERN Multimedia

This paper studies an algebraic invariant of virtual knots called the biquandle. The biquandle generalizes the fundamental group and the quandle of virtual knots. The approach taken in this paper to the biquandle emphasizes understanding its structure in terms of compositions of morphisms, where elementary morphisms are associated to oriented classical and virtual crossings in the diagram.

Virtual environment tactile system  

Energy Technology Data Exchange (ETDEWEB)

A method for providing a realistic sense of touch in virtual reality by means of programmable actuator assemblies is disclosed. Each tactile actuator assembly consists of a number of individual actuators whose movement is controlled by a computer and associated drive electronics. When an actuator is energized, the rare earth magnet and the associated contactor, incorporated within the actuator, are set in motion by the opposing electromagnetic field of a surrounding coil. The magnet pushes the contactor forward to contact the skin resulting in the sensation of touch. When the electromagnetic field is turned off, the rare earth magnet and the contactor return to their neutral positions due to the magnetic equilibrium caused by the interaction with the ferrous outer sleeve. The small size and flexible nature of the actuator assemblies permit incorporation into a glove, boot or body suit. The actuator has additional applications, such as, for example, as an accelerometer, an actuator for precisely controlled actuations or to simulate the sensation of braille letters. 28 figs.

Sociocultural patterning of neural activity during self-reflection  

DEFF Research Database (Denmark)

Western cultures encourage self-construals independent of social contexts whereas East Asian cultures foster interdependent self-construals that rely on how others perceive the self. How are culturally specific self-construals mediated by the human brain? Using functional MRI, we monitored neural responses from adults in East Asian (Chinese) and Western (Danish) cultural contexts during judgments of social, mental, and physical attributes of themselves and public figures to assess cultural influences on self-referential processing of personal attributes in different dimensions. We found that judgments of self vs. a public figure elicited greater activation in the medial prefrontal cortex (mPFC) in Danish than in Chinese participants regardless of attribute dimensions for judgments. However, self-judgments of social attributes induced greater activity in the temporoparietal junction (TPJ) in Chinese than in Danish participants. Moreover, the group difference in TPJ activity was mediated by a measure of a cultural value (i.e., interdependence of self-construal). Our findings suggest that individuals in different sociocultural contexts may learn and/or adopt distinct strategies for self-reflection by changing the weight of the mPFC and TPJ in the social brain network.

Predictors of multiple tooth loss among socioculturally diverse elderly subjects.  

UK PubMed Central (United Kingdom)

PURPOSE: This study identifies clinical factors that predict multiple tooth loss in a socioculturally diverse population of older adults. MATERIALS AND METHODS: A total of 193 participants from English-, Chinese-, or Punjabi-speaking communities in Vancouver, British Columbia, with low incomes and irregular use of dental services were followed for 5 years as part of a clinical trial of a 0.12% chlorhexidine mouthrinse. The participants were interviewed and examined clinically, including panoramic radiographs, at baseline and annually for 5 years. Binary logistic regression was used to test the hypothesis that there was no difference between incidence of multiple (? 3) tooth loss in older people with various biologic, behavioral, prosthodontic, and cultural variables over 5 years. RESULTS: Multiple tooth loss, which was distributed similarly among the groups in the trial, occurred in 39 (20%) participants over 5 years. The use of removable prostheses was the best predictor of loss, followed by the number of carious surfaces and number of sites with gingival attachment loss > 6 mm. The pattern of prediction was consistent across the three linguocultural groups. CONCLUSION: The use of removable dentures was the dominant predictor of multiple tooth loss in the three communities, but that tooth loss was not significantly associated with the cultural heritage of the participants.

Religion as dialogical resource: a socio-cultural approach.  

UK PubMed Central (United Kingdom)

William James proposed a psychological study of religion examining people's religious experiences, and to see in what sense these were good for them. The recent developments of psychology of religion moved far from that initial proposition. In this paper, we propose a sociocultural perspective to religion that renews with that initial stance. After recalling Vygtotsky's core ideas, we suggest that religion, as cultural and symbolic system, participates to the orchestration of human activities and sense-making. Such orchestration works both from within the person, through internalized values and ideas, and from without, through the person's interactions with others, discourses, cultural objects etc. This leads us to consider religions as supporting various forms of dialogical dynamics-intra-psychological dialogues, interpersonal with present, absent or imaginary others, as well as inter-group dialogues-which we illustrate with empirical vignettes. The example of religious tensions in the Balkans in the 90's highlights how much the historical-cultural embeddedness of these dynamics can also lead to the end of dialogicality, and therefore, sense-making.

Exploring complex sociocultural situations through soft operational research  

Scientific Electronic Library Online (English)

Full Text Available Abstract in english A paradigm can be thought of as a living commodity system, carried by a self-organising group. The commodity is often "practical knowledge", and the paradigm maintains a life cycle that begins with commodity gestation, leading to commodity depreciation through death or transformation. During its normal life processes paradigm grow their commodities incrementally, but the growth processes become bounded through the very conceptualisations that made them successful, limitin (more) g their pragmatic capabilities. Paradigms have not only normal lives, but also post-normal lives. In the current cultural environment normal paradigmatic life processes are said to be hard, while post-normal ones are said to be soft, with this change being facilitated through epistemological shift. An illustration of a new framework called sociohistory is shown to be a soft OR approach. Its purpose is to describe, explore and evaluate complex sociocultural problem situations, with the potential to create intervention strategies that might be able to improve them.

Workplace Learning in Veterinary Education: A Sociocultural Perspective.  

UK PubMed Central (United Kingdom)

Veterinary practice is a broad sphere of professional activity encompassing clinical activity and other vocational opportunities conducted in rapidly changing contemporary social conditions. Workplace learning is an important but resource-intensive component of educating students for practice. This conceptual article argues that literature on workplace learning in the veterinary context is dominated by descriptive accounts and that there is a dearth of theoretically informed research on this topic. Framing veterinary practice as a social, relational, and discursive practice supports the use of workplace learning theories developed from a sociocultural perspective. Situated learning theory, with its associated concepts of communities of practice and legitimate peripheral participation, and workplace learning theory focused on workplace affordances and learner agency are discussed. Two composite examples of student feedback from veterinary clinical learning illustrate the concepts, drawing out such themes as the roles of teachers and learners and the assessment of integrated practice. The theoretical perspective described in this article can be used to inform development of models of workplace learning in veterinary clinical settings; relevant examples from medical education are presented.

[Environmental and sociocultural parameters affecting nutrition in Third World countries  

UK PubMed Central (United Kingdom)

The thrust of this paper is an analysis of the environmental and sociocultural parameters affecting dietary patterns in Third World countries. The author utilizes data from several studies to emphasize her thesis that malnutrition in developing societies is not an entity caused simply by income constraints, or food availability, but rather that malnutrition constitutes a critical entity resulting from a constellation of problems, ranging from environmental stresses, to social inequities to cultural factors. Special discussion is given to the variables of income distribution, social stratification and food beliefs as major contributing influences of malnutrition in Third World countries. The problems facing newly migrating urban squatters--or what is known as "societies in transition" in the context of high unemployment and new demands for food--are also dealt with in the Latin American setting. The author discusses the importance to recognize that since the etiology of malnutrition is ecologically-based; therefore, the approaches to solve this problem should--also by definition--be of an ecological nature. The need to further develop meaningful conceptual models--in contrast to utilizing "imported" ones--in order to study and understand the nature and magnitude of malnutrition problems in Third World countries is also stressed.

Sociocultural Beliefs, As Well As Goodness of Fit, Influence the Effectiveness of Coping in Japanese Workers.  

UK PubMed Central (United Kingdom)

BACKGROUND: Although the goodness-of-fit hypothesis (GOFH) is one of the most important theories in research about the effect of coping on distress related to different stressful situations, there has been a mixed response to it in the literature. PURPOSE: The present study examined whether the effect of the sociocultural context in stressful situations is consistent with the GOFH. The study investigated sociocultural beliefs about the appropriateness of different coping strategies in a given group as the sociocultural context. METHOD: Japanese employees (N?=?1,156) of an information technology company reported their appraisal of stressors' controllability, the coping strategies they employed for the stressors, their sociocultural beliefs about coping strategies, and their psychological distress in response to the stressors. RESULTS: The GOFH was supported only for problem-focused coping with task stressors and not for interpersonal stressors. The applicability of the GOFH differed by sociocultural beliefs about coping, namely an appraisal of what coworkers might think about the appropriateness of the coping method. CONCLUSION: These results suggest that it is important for managing stress to consider the sociocultural context as well as the GOFH.

[Virtual reality in neurosurgery].  

UK PubMed Central (United Kingdom)

DEFINITION: Virtual reality enables users to immerse themselves in a virtual three-dimensional world and to interact in this world. The simulation is different from the kind in computer games, in which the viewer is active but acts in a nonrealistic world, or on the TV screen, where we are passively driven in an active world. In virtual reality elements look realistic, they change their characteristics and have almost real-world unpredictability. USE OF VIRTUAL REALITY: Virtual reality is not only implemented in gambling dens and the entertainment industry but also in manufacturing processes (cars, furniture etc.), military applications and medicine. Especially the last two areas are strongly correlated, because telemedicine or telesurgery was originated for military reasons to operate on war victims from a secure distance or to perform surgery on astronauts in an orbiting space station. In medicine and especially neurosurgery virtual-reality methods are used for education, surgical planning and simulation on a virtual patient.

Cochrane review: virtual reality for stroke rehabilitation.  

UK PubMed Central (United Kingdom)

AIM: Virtual reality and interactive video gaming are innovative therapy approaches in the field of stroke rehabilitation. The primary objective of this review was to determine the effectiveness of virtual reality on motor function after stroke. The impact on secondary outcomes including activities of daily living was also assessed. METHODS: Randomised and quasi-randomised controlled trials that compared virtual reality with an alternative or no intervention were included in the review. The authors searched the Cochrane Stroke Group Trials Register, the Cochrane Central Register of Controlled Trials, electronic databases, trial registers, reference lists, Dissertation Abstracts, conference proceedings and contacted key researchers and virtual reality manufacturers. Search results were independently examined by two review authors to identify studies meeting the inclusion criteria. RESULTS: Nineteen studies with a total of 565 participants were included in the review. Variation in intervention approaches and outcome data collected limited the extent to which studies could be compared. Virtual reality was found to be significantly more effective than conventional therapy in improving upper limb function (standardised mean difference, SMD) 0.53, 95% confidence intervals [CI] 0.25 to 0.81)) based on seven studies, and activities of daily living (ADL) function (SMD 0.81, 95% CI 0.39 to 1.22) based on three studies. No statistically significant effects were found for grip strength (based on two studies) or gait speed (based on three studies). CONCLUSION: Virtual reality appears to be a promising approach however, further studies are required to confirm these findings.

Virtual World Security Inspection  

Directory of Open Access Journals (Sweden)

Full Text Available Virtual property theft is a serious problem that exists in virtual worlds. Legitimate users of these worlds invest considerable amounts of time, effort and real-world money into obtaining virtual property, but unfortunately, are becoming victims of theft in high numbers. It is reported that there are over 1 billion registered users of virtual worlds containing virtual property items worth an estimated US$50 billion dollars. The problem of virtual property theft is complex, involving many legal, social and technological issues. The software used to access virtual worlds is of great importance as they form the primary interface to these worlds and as such the primary interface to conduct virtual property theft. The security vulnerabilities of virtual world applications have not, to date, been examined. This study aims to use the process of software inspection to discover security vulnerabilities that may exist within virtual world software – vulnerabilities that enable virtual property theft to occur. Analyzing three well know virtual world applications World of Warcraft, Guild Wars and Entropia Universe, this research utilized security analysis tools and scenario testing with focus on authentication, trading, intruder detection and virtual property recovery. It was discovered that all three examples were susceptible to keylogging, mail and direct trade methods were the most likely method for transferring stolen items, intrusion detection is of critical concern to all VWEs tested, stolen items were unable to be recovered in all cases and lastly occurrences of theft were undetectable in all cases. The results gained in this study present the key problem areas which need to be addressed to improve security and reduce the occurrence of virtual property theft.

Conditions for generating virtual channels in cochlear prosthesis systems.  

Science.gov (United States)

Simultaneous electrical stimulation of neighboring electrodes in cochlear prosthesis systems generates channel interaction. However, intermediate channels, or virtual channels between the neighboring electrodes can be created through controlled channel interaction. This effect may be exploited for sending new information to the hearing nerves by stimulating in a suitable manner. The actual stimulation sites are therefore not limited to the number of electrodes. Clinical experiments, however, show that virtual channels are not always perceived. In this paper, electrical simulation with finite element analysis on a half turn human cochlea model is adopted to model the virtual channel effect, and the conditions for generating virtual channels are discussed. Five input current ratios (100/0, 70/30, 50/50, 30/70, 0/100) are applied to generate virtual channels. Three electrode arrays parameters are taken into consideration: distance between electrode contact and modiolus, spacing between adjacent electrode contacts and scale of electrode contact size. By observing the activating function contours, the virtual channel patterns and performances can be measured and examined. The results showed that a broad excitation pattern is necessary to produce the kind of electrode interaction that can form distinct virtual channels. PMID:19085105

Socio-cultural sustainability of pig production: Citizen perceptions in the Netherlands and Denmark  

DEFF Research Database (Denmark)

Many sustainability studies of animal production consider three pillars: the economic, environmental and socio-cultural. Farmers and animal scientists tend to put most emphasis on the economic and environmental pillar and largely ignore the socio-cultural pillar. Socio-cultural sustainability refers to social perceptions of animal farming, including social appreciations and concerns of animal production systems. Integration of social demands and values in the production sector is a prerequisite to justify animal production within a society. The objective of the present study was therefore to gain further insights into socio-cultural sustainability of pig production. Many citizens may not know what contemporary pig production actually entails. To give people a real life experience with pig production, we conducted farm visits with citizen panels with 18 respondents in the Netherlands and 8 respondents in Denmark. In both countries, respondents were divided over two panels and each panel visited a conventional and an organic pig farm. During the farm visits respondents noted their sensory experiences — what do you smell, hear, see and feel? In addition, each respondent made pictures of six positive and six negative aspects on the farms for which they had to write a motivation. The qualitative analysis resulted in seven socio-cultural themes (SCT) of pig production namely: 1) meat production, 2) farm activities, 3) farm income, 4) animals, 5) housing system, 6) environment and nature, and 7) culture and landscape. Each SCT included several socio-cultural aspects (appreciations, SCA) and socio-cultural issues (concerns, SCI). We identified 31 SCAs in the Netherlands and 33 SCAs in Denmark, of which 29 were SCIs in both countries. Although many issues were associated with animal welfare, the results also showed that social concerns of pig production extended beyond animal welfare. In general it can be stated that citizens are strongly concerned about overexploitation of animals in contemporary pig production systems, but at the same time they appreciate the dynamism in a pig farm including certain modern developments.

EDITORIAL: Close contact Close contact  

Science.gov (United States)

The development of scanning probe techniques, such as scanning tunnelling microscopy [1], has often been touted as the catalyst for the surge in activity and progress in nanoscale science and technology. Images of nanoscale structural detail have served as an invaluable investigative resource and continue to fascinate with the fantastical reality of an intricate nether world existing all around us, but hidden from view of the naked eye by a disparity in scale. As is so often the case, the invention of the scanning tunnelling microscope heralded far more than just a useful new apparatus, it demonstrated the scope for exploiting the subtleties of electronic contact. The shrinking of electronic devices has been a driving force for research into molecular electronics, in which an understanding of the nature of electronic contact at junctions is crucial. In response, the number of experimental techniques in molecular electronics has increased rapidly in recent years. Scanning tunnelling microscopes have been used to study electron transfer through molecular films on a conducting substrate, and the need to monitor the contact force of scanning tunnelling electrodes led to the use of atomic force microscopy probes coated in a conducting layer as studied by Cui and colleagues in Arizona [2]. In this issue a collaboration of researchers at Delft University and Leiden University in the Netherlands report a new device architecture for the independent mechanical and electrostatic tuning of nanoscale charge transport, which will enable thorough studies of molecular transport in the future [3]. Scanning probes can also be used to pattern surfaces, such as through spatially-localized Suzuki and Heck reactions in chemical scanning probe lithography. Mechanistic aspects of spatially confined Suzuki and Heck chemistry are also reported in this issue by researchers in Oxford [4]. All these developments in molecular electronics fabrication and characterization provide alternative means to produce nanoscale device elements, such as carbon nanotube transistors [5] and high-density memory crossbar circuits [6]. Recently, the use of scanning tunnelling microscopes has broached a new field of research, which is currently attracting enormous interest—single molecule detection. In issue 25 of Nanotechnology researchers in Houston reported unprecedented sensitivities using localized surface plasmon resonance shifts of gold bipyramids to detect concentrations of substances down to the single molecule level [7]. In issue 26 a collaboration of researchers from the US and Czech Republic describe a different approach, namely tunnelling recognition. In their topical review they describe hydrogen-bond mediated tunnelling and the associated experimental methods that facilitate the detection of single molecules in a tunnel junction using chemically functionalized electrodes [8]. The nanoworld depicted by scanning probe microgaphs over 20 years ago may have looked as extraterrestrial as any science fiction generated alien terrain, but though study and analysis these nano-landscapes have become significantly less alien territory. The work so far to unveil the intricacies of electronic contact has been a story of progress in investigating this new territory and manipulating the mechanisms that govern it to formulate new devices and delve deeper into phenomena at the nanoscale.

Virtual reality for engineering  

CERN Document Server

Virtual Reality for Engineers. Virtual Reality is a very powerful visualization technique for 3D data, which can bring enormous benefits to engineering design. CAD models can be exported to a VR application and used as "Virtual Prototypes". Virtual Prototypes are an ideal replacement for wooden models as they can be generated automatically from most CAD products. They are totally reliable, they can be updated in a matter of minutes, and they allow designers to explore them from inside, on a one-to-one scale and using a 3D-stereo vision. Navigation can be performed using a number of instinctive tools, such as joysticks, spaceballs, VR helmets and 3D mice. The lectures will cover today's Virtual Reality products and methods, and describe how to transform CAD models into Virtual Prototypes. A "hands on" VR experience featuring the LHC detectors models can be organized for people interested.

Virtual reality for stroke rehabilitation.  

UK PubMed Central (United Kingdom)

BACKGROUND: Virtual reality and interactive video gaming have emerged as new treatment approaches in stroke rehabilitation. In particular, commercial gaming consoles are being rapidly adopted in clinical settings; however, there is currently little information about their effectiveness. OBJECTIVES: To evaluate the effects of virtual reality and interactive video gaming on upper limb, lower limb and global motor function after stroke. SEARCH STRATEGY: We searched the Cochrane Stroke Group Trials Register (March 2010), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2010, Issue 1), MEDLINE (1950 to March 2010), EMBASE (1980 to March 2010) and seven additional databases. We also searched trials registries, conference proceedings, reference lists and contacted key researchers in the area and virtual reality equipment manufacturers. SELECTION CRITERIA: Randomised and quasi-randomised trials of virtual reality ('an advanced form of human-computer interface that allows the user to 'interact' with and become 'immersed' in a computer-generated environment in a naturalistic fashion') in adults after stroke. The primary outcomes of interest were: upper limb function and activity, gait and balance function and activity and global motor function. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials based on pre-defined inclusion criteria, extracted data and assessed risk of bias. A third review author moderated disagreements when required. The authors contacted all investigators to obtain missing information. MAIN RESULTS: We included 19 trials which involved 565 participants. Study sample sizes were generally small and interventions and outcome measures varied, limiting the ability to which studies could be compared. Intervention approaches in the included studies were predominantly designed to improve motor function rather than cognitive function or activity performance. The majority of participants were relatively young and more than one year post stroke. Primary outcomes: results were statistically significant for arm function (standardised mean difference (SMD) 0.53, 95% confidence intervals (CI) 0.25 to 0.81 based on seven studies with 205 participants). There were no statistically significant effects for grip strength or gait speed. We were unable to determine the effect on global motor function due to insufficient numbers of comparable studies. Secondary outcomes: results were statistically significant for activities of daily living (ADL) outcome (SMD 0.81, 95% CI 0.39 to 1.22 based on three studies with 101 participants); however, we were unable to pool results for cognitive function, participation restriction and quality of life or imaging studies. There were few adverse events reported across studies and those reported were relatively mild. Studies that reported on eligibility rates showed that only 34% (standard deviation (SD) 26, range 17 to 80) of participants screened were recruited. AUTHORS' CONCLUSIONS: We found limited evidence that the use of virtual reality and interactive video gaming may be beneficial in improving arm function and ADL function when compared with the same dose of conventional therapy. There was insufficient evidence to reach conclusions about the effect of virtual reality and interactive video gaming on grip strength or gait speed. It is unclear at present which characteristics of virtual reality are most important and it is unknown whether effects are sustained in the longer term.

Virtual Arbitrage Pricing Theory  

CERN Document Server

We generalize the Arbitrage Pricing Theory (APT) to include the contribution of virtual arbitrage opportunities. We model the arbitrage return by a stochastic process. The latter is incorporated in the APT framework to calculate the correction to the APT due to the virtual arbitrage opportunities. The resulting relations reduce to the APT for an infinitely fast market reaction or in the case where the virtual arbitrage is absent. Corrections to the Capital Asset Pricing Model (CAPM) are also derived.

Metodologías que optimizan la comunicación en entornos de aprendizaje virtual Methodologies to Improve Communication in Virtual Learning Environments  

Directory of Open Access Journals (Sweden)

Full Text Available Los principales avances educativos y el actual auge de los modelos de formación se deben a la incorporación de las tecnologías de la información y la comunicación, así como a la aplicación de elementos pedagógicos provenientes de aproximación sociocultural. Desde este enfoque educativo, la comunicación es un elemento esencial en los procesos de aprendizaje y enseñanza, por tanto, estas herramientas, entendidas como artefactos tecnológicos de producción cultural, ofrecen un excelente soporte innovador, permitiendo contar con entornos virtuales de aprendizaje, como las ofrecidas por las plataformas para el aprendizaje colaborativo mediado por ordenador (CSCL) que favorecen la comunicación, la mediación y la construcción compartida del conocimiento (coconstrucción). La comunicación virtual es uno de los aspectos esenciales en la formación a distancia como también lo es la formación semipresencial (blended learning), que comienza a adquirir un importante papel en contextos presenciales que utilizan estos entornos como instancias complementarias destinadas a extender la clase fuera de las fronteras del aula. En este sentido, es relevante un aporte de las diversas experiencias telemáticas de aprendizaje que usan modalidades de aprendizaje cooperativo o colaborativo en entornos virtuales. En el trabajo que presentamos se organizan y describen experiencias de aprendizaje cooperativo y colaborativo mediado por ordenador con estudiantes de diferentes niveles educativos. Los resultados y conclusiones de dichas experiencias evidencian una mejora de habilidades sociales, habilidades comunicativas, motivación y rendimiento académico independientemente del tipo de modalidad de aprendizaje compartido.The main advances in education and the current expansion of training models are due to the incorporation of information and communication technologies (ICTs), as well as pedagogical elements arising from the socio-cultural approach. Communication is an essential element in the processes of teaching and learning in this educational approach. Therefore, ICTs offer us an excellent innovative support, allowing use to make use of such virtual learning environments as Collaborative Computer-Assisted Learning (CSCL), which enables communication, mediation and knowledge construction. Virtual communication is one of the essential elements in blended learning, and it is even starting to play an important role in traditional teaching environments. In this regard, we consider that a contribution from different teaching and learning experiences in virtual scenarios (Synergeia; BSCW; Moodle…) is necessary. In this article, we describe several cooperative and collaborative computer-mediated learning experiences with students of different educational levels. The results and conclusions on Collaborative Computer-Assisted Learning experiences reveal an improvement in motivation, academic performance and the development of social and communication skills, regardless of the use of cooperative (cooperative learning techniques) or collaborative learning.

Debugging the virtual machine  

Energy Technology Data Exchange (ETDEWEB)

A computer program is really nothing more than a virtual machine built to perform a task. The program`s source code expresses abstract constructs using low level language features. When a virtual machine breaks, it can be very difficult to debug because typical debuggers provide only low level machine implementation in formation to the software engineer. We believe that the debugging task can be simplified by introducing aspects of the abstract design into the source code. We introduce OODIE, an object-oriented language extension that allows programmers to specify a virtual debugging environment which includes the design and abstract data types of the virtual machine.

The Impact of Socio-Cultural Environment on Entrepreneurial Emergence: An Empirical Analysis of Nigeria Society  

Directory of Open Access Journals (Sweden)

Full Text Available The paper presents an analytical and evaluative study of the impact of socio-cultural environment on entrepreneurial emergence. The study uses as reference case, the socio-cultural characteristics of Nigerian society and their role in the emergence of entrepreneurs in Nigeria. A survey research design was adopted and data collected through the instruments of questionnaire and personal interview. The study revealed that the Nigerian socio-cultural characteristics, in some ways, have provided impetus for entrepreneurial emergence among Nigerians, but in some other ways, have enormously hindered the emergence of entrepreneurs. This disproves the general notion that the Nigerian society absolutely does not provide opportunities for entrepreneurial emergence. The paper concludes that, in general, socio-cultural environment significantly impact on entrepreneurial emergence in society. Beyond the negative or adverse socio-economic circumstances of individuals, the culture and value system of a people is a great determinant of the desire and capacity of people becoming entrepreneurs. The paper therefore, recommends that certain traditions and values in society which have remained barriers to people particularly women becoming entrepreneurs must be dropped or modified to pave way for the emergence of entrepreneurs among men and women in Nigeria and other societies.Key words: Impact; Entrepreneurial emergence; Socio-cultural environment; Value re-engineering and re-orientation

The interaction of ethnicity, sociocultural factors, and gender in clinical psychopharmacology.  

Science.gov (United States)

There is increased interest in the role that ethnicity, sociocultural factors, and gender play in research, health care delivery, and response to intervention. The impact of these factors on AIDS awareness programs, on the phenomenology of suicide and anorexia nervosa, and on clinical psychopharmacology in a homogeneous population is discussed. Risky sex practices can be related to cultural norms that stigmatize condom use and sex education; economic deprivation; and male dominance. Gender, cultural, and ethnic demographics can identify high-risk groups as well as influence effective interventions. Suicide rates and risk factors are compared in African-American, Canadian Native, and South Korean adolescents. Academic stress was a differential risk factor for the Koreans. Anorexia nervosa predominantly affects women and has cultural differences in prevalence. The homogeneous population in Hong Kong illustrates the impact of ethnicity, sociocultural factors, and gender on clinical psychopharmacology. Attention to ethnicity, sociocultural factors, and gender can individualize and improve the effectiveness of clinical psychopharmacology. PMID:8783899

Muscle dysmorphia, gender role stress, and sociocultural influences: an exploratory study.  

UK PubMed Central (United Kingdom)

Our study explored the contribution of gender role stress (GRS) and sociocultural appearance demands to symptoms of muscle dysmorphia (MD) in a college sample of 219 women and 154 men. For women, five GRS subscales, sociocultural appearance demands, age, and frequency of aerobic exercise predicted MD symptoms (model R2 = .33; F(8,210) = 12.81, p < . 001); for men, only one GRS subscale, age, and sociocultural appearance demands predicted MD symptoms (model R2 = .40; F(3,150) = 9.52, p < .001). Post hoc analyses revealed that a small number of items explained a substantial portion of the variation, suggesting that MD may be more related to specific perceptions of pressure to attain an attractive body than to global gender role stress.

Sociocultural contexts of attempting suicide among Iranian youth: a qualitative study.  

Science.gov (United States)

This paper seeks to illuminate the sociocultural contexts of attempting suicide among Iranian youth. A qualitative approach was employed to uncover the social and cultural dimensions of attempting suicide. In-depth interviews were conducted with 25 participants aged 14-17 years who attempted suicide and were admitted to 2 of the hospitals in Isfahan. A thematic analysis approach was employed. The main themes identified were failure in love, family problems, study, pressure of high expectations and poverty. The findings suggest significant sociocultural influence on attempting suicide in the Islamic Republic of Iran. Exploring sociocultural aspects of suicide is critical in providing effective and culturally-sensitive suicide prevention and care programmes. PMID:21796972

Understanding electronic medical record adoption in the United States: communication and sociocultural perspectives.  

UK PubMed Central (United Kingdom)

BACKGROUND: This paper adopts a communication and sociocultural perspective to analyze the factors behind the lag in electronic medical record (EMR) adoption in the United States. Much of the extant research on this topic has emphasized economic factors, particularly, lack of economic incentives, as the primary cause of the delay in EMR adoption. This prompted the Health Information Technology on Economic and Clinical Health Act that allow financial incentives through the Centers of Medicare and Medicaid Services for many health care organizations planning to adopt EMR. However, financial incentives alone have not solved the problem; many new innovations do not diffuse even when offered for free. Thus, this paper underlines the need to consider communication and sociocultural factors to develop a better understanding of the impediments of EMR adoption. OBJECTIVE: The objective of this paper was to develop a holistic understanding of EMR adoption by identifying and analyzing the impact of communication and sociocultural factors that operate at 3 levels: macro (environmental), meso (organizational), and micro (individual). METHODS: We use the systems approach to focus on the 3 levels (macro, meso, and micro) and developed propositions at each level drawing on the communication and sociocultural perspectives. RESULTS: Our analysis resulted in 10 propositions that connect communication and sociocultural aspects with EMR adoption. CONCLUSIONS: This paper brings perspectives from the social sciences that have largely been missing in the extant literature of health information technology (HIT) adoption. In doing so, it implies how communication and sociocultural factors may complement (and in some instances, reinforce) the impact of economic factors on HIT adoption.

Full Text Available Este trabalho compara as experiências de sala de aula (ESA) de duas universitárias na aprendizagem de língua inglesa. As ESA emergiram de entrevistas individuais, onde vídeos das aulas promoveram a reflexão. A análise revelou que experiências de natureza cognitiva, social ou afetiva influem diretamente no processo de aprendizagem e as que se referem ao contexto, à história, crenças e metas dos alunos influem indiretamente no mesmo. A singularidade de algumas experiências levou à sua categorização como ESA individuais (ESAI). Ao comparar as ESAI de duas informantes, a importância da análise sociocultural do processo de aprendizagem de sala de aula fica evidente. Concluiremos com uma defesa do valor da teoria sociocultural no estudo da aprendizagem de língua estrangeira em sala de aula e com a apresentação das implicações deste estudo para pesquisadores e professores. This paper compares the classroom experiences (CEs) of two university students in their process of learning English as a foreign language (EFL). The CEs emerged from individual interviews, where classroom videos promoted reflection. The analysis revealed that cognitive, social and affective experiences directly influence the learning process and that those which refer to setting, learner’s personal background, beliefs and goal influence the learning process indirectly. The analysis also revealed the singularity of some of these CEs that led to their categorization as individual CEs (ICEs). When comparing the ICEs of the two participants, the importance of a sociocultural analysis of the classroom learning process becomes evident. We conclude with an analysis of the value of sociocultural theory in the study of classroom EFL learning and with the implications of this study for teachers and researchers.

Directory of Open Access Journals (Sweden)

Full Text Available The motive of the «disinherited widow» has found until now little consideration in literature. Therefore it is interesting to study two novels published within a few decades of each other and which address this problem: Middlemarch (1871/1872), one of the well-known novels by George Eliot, and Pilar Prim (1906) by Narcís Oller. Although it has not been proven, it seems plausible that Oller knew the English novel, because he read a lot of contemporary literature and, besides this, maintained close contact with French literary circles, where the French translations of Eliot’s novels were familiar. This article studies the socio-cultural differences, analogies and consequences of the forced renunciation of the deceased husband’s fortune of two wealthy widows, because a codicile in testament hinders a second marriage. The main problem is not this renunciation, but that the second husband is poor, and so the widow must choose love, poverty and social isolation or wealth, loneliness and social appreciation.

High availability using virtualization  

CERN Multimedia

High availability has always been one of the main problems for a data center. Till now high availability was achieved by host per host redundancy, a highly expensive method in terms of hardware and human costs. A new approach to the problem can be offered by virtualization. Using virtualization, it is possible to achieve a redundancy system for all the services running on a data center. This new approach to high availability allows to share the running virtual machines over the servers up and running, by exploiting the features of the virtualization layer: start, stop and move virtual machines between physical hosts. The system (3RC) is based on a finite state machine with hysteresis, providing the possibility to restart each virtual machine over any physical host, or reinstall it from scratch. A complete infrastructure has been developed to install operating system and middleware in a few minutes. To virtualize the main servers of a data center, a new procedure has been developed to migrate physical to virtu...

Trust in Virtual Universities  

Directory of Open Access Journals (Sweden)

Full Text Available The number of students enrolled at Iranian virtual Universities during 2004-2007 years, annually accounted for less than 0.5% of traditional Iranian universities enrolment. The low rate of virtual Universities enrolment might be due to a low level of student's trust in this type of educational institution. Students with low trust in virtual universities may be less likely to enroll in distant learning courses. Many factors contribute to student's trust level, including perceptions of the virtual university's quality of education, teacher's skills, academic reputation, etc...We examined five factors (academic reputation, administrative efficacy, size of institution, fairly tuition and Suitable environmental Conditions) as antecedents and three factors (student's attitude, willingness and risk taking) as consequences of student's trust. The relationships among factors were determined using a structural equations model and path analysis. Our analysis suggests that the academic reputation and the Suitable environmental Conditions for activity a virtual university is the most important determinants of student's trust. Furthermore, the student's trust level significantly affects student's willingness to study in virtual universities. Our results have implications for the development of theories as well as policies for the virtual universities.

Realistic Haptic Rendering of Interacting Deformable Objects in Virtual Environments  

CERN Multimedia

A new computer haptics algorithm to be used in general interactive manipulations of deformable virtual objects is presented. In multimodal interactive simulations, haptic feedback computation often comes from contact forces. Subsequently, the fidelity of haptic rendering depends significantly on contact space modeling. Contact and friction laws between deformable models are often simplified in up to date methods. They do not allow a "realistic" rendering of the subtleties of contact space physical phenomena (such as slip and stick effects due to friction or mechanical coupling between contacts). In this paper, we use Signorini's contact law and Coulomb's friction law as a computer haptics basis. Real-time performance is made possible thanks to a linearization of the behavior in the contact space, formulated as the so-called Delassus operator, and iteratively solved by a Gauss-Seidel type algorithm. Dynamic deformation uses corotational global formulation to obtain the Delassus operator in which the mass and s...

The virtual Haken conjecture  

CERN Multimedia

We prove that cubulated hyperbolic groups are virtually special. The proof relies on results of Haglund and Wise which also imply that they are linear groups, and quasi-convex subgroups are separable. A consequence is that closed hyperbolic 3-manifolds have finite-sheeted Haken covers, which resolves the virtual Haken question of Waldhausen and Thurston's virtual fibering question. An appendix to this paper by Agol, Groves, and Manning proves a generalization of the main result of "Residual finiteness, QCERF and fillings of hyperbolic groups".

Twisted virtual biracks and their twisted virtual link invariants  

CERN Multimedia

A virtual link can be understood as a link in a trivial I-bundle over an orientable compact surface with genus. A twisted virtual link is a link in a trivial I-bundle over a not-necessarily orientable compact surface. A twisted virtual birack is an algebraic structure with axioms derived from the twisted virtual Reidemeister moves. We extend a method previously used with racks and biracks to the twisted case to define computable invariants of twisted virtual links using finite twisted virtual biracks with birack rank $N\\ge 1$. As an application, we classify twist structures on the virtual Hopf link.

Reality in Virtual Learning : Challenges without the Classroom  

DEFF Research Database (Denmark)

The development of ITC has increased focus onto distance learning programs worldwide. Most universities today offer distance learning programs that are based on the Internet. This development represents a fundamental change in the very logic of being a university. It is no longer enough to rely on professor authority. How can one create a learning situation that enables the university to remain viable? In most western countries, the professors have dominated the learning processes at universities. Since the 50s, learning has been about learning-in, memorizing, and cram (Illeris, 2000) where professors most often decide what and when one could learn by providing the context and substance. In this perspective, the student has a role which is close to the one of a passive receiver, and s/he is mainly preoccupied with the problem of generating substance in memory most efficiently. Today, technology challenges our pedagogical reasoning in many ways. However, old pedagogical models often prevail. We see practices where lectures, notes and course information are published on the Internet, where ICT helps professor-student communication, and online based student tests. These attempts are based on old-time educational logic. There are fewer attempts to use ICT according to a different pedagogical perspective than the old professor authoritarian model. The purpose of this paper is to illuminate some challenges virtual students experience when facing a new ICT-based learning situation. We will try to explore and develop understandings of what it might mean to be a student when learning occurs within a virtual problem based learning landscape. When students are used to the traditional classroom, challenges appear in the twilight zone between two pedagogical practices. How do the students cope with challenges that a new virtual program demands, and what paradoxes and ambiguities appear when old learning processes do not work anymore? The present focus reflects an existential-phenomenological point of departure. This perspective is based on the philosophical writings of Søren Kierkegaard and Martin Heidegger (1927/1996; "Being and Time"), and the successors Hans-Georg Gadamer and Paul Ricoeur. The work is also inspired of the father of culturalism - Jerome Bruner (1996) and Wenger's (1998) community of practice. Thompson (1997) is an inspiration through his initiator of hermeneutical endeavor within consumer research. The consequences of this perspective are that the student and his/her experiences and learning cannot be separated from the student's existence. As for the subject matter, we cannot separate the student from his/her studying. Learning becomes a profoundly socio-cultural process which has to be studied according to the situation and context in which it appears. It is the heart of this project that the twilight zone between cultural roles might reveal some interesting knowledge about the introduction of ICT and its consequences. The socio-cultural conditions of present society set the context for the hermeneutic analysis of meanings and salient life concerns that learning experiences hold for time-pressured virtual students with high degree of responsibilities. An existential-phenomenological assumption is that individuals would tend to interpret their experiences within present socio-cultural framework. Due to its novel characteristics of the program, however, it is particularly interesting to investigate the role that virtual studying serves in the construction of reality and meaning. Furthermore, as it is assumed that experiences cannot be separated from who one is (being-in-the world), the process of human change during virtual studying is also expected to influence salient types of learning, the student's work practice, and his/her private practice.

The relationship between sociocultural pressure to be thin and body dissatisfaction in preadolescent girls.  

Science.gov (United States)

This study investigates the relationships among sociocultural pressures to be thin, internalisation of the thin ideal, social comparison, body mass index, and body dissatisfaction in young girls. One hundred and fifty-three 10-13 year old girls completed measures assessing sociocultural pressure to be thin, media exposure, body dissatisfaction, social comparison, and internalisation of the thin ideal. Although sociocultural factors, as a group, were significantly associated with internalisation of the thin ideal, perceived media pressure was the only sociocultural influence uniquely related to internalisation of the thin ideal. Perceived pressure to be thin delivered by the media was found to be associated with body dissatisfaction via internalisation of the thin ideal. The relationship between internalisation of the thin ideal and body dissatisfaction was also partially influenced by social comparison. Body mass was found to have a direct association with body dissatisfaction. A model incorporating the relationships among media pressure, internalisation of the thin ideal, social comparison, and body dissatisfaction is proposed. PMID:15000967

ffered helped settle the controversies. Virtual memory isnow so ordinary that few people think much about it. That this has happened is one ofthe engineering triumphs of the computer age.Virtual-memory designers have three major concerns. (1) Address mapping, the processof translating virtual addresses to memory addresses, should easily accommodate thekinds of objects that programmers are working with. (2) Address translation should beefficient, costing no more than 3% of hardware execution speed. (3) Overall systemperformance, measured by throughput and response time, should be within 10% of thebest possible performance attainable for a given workload.MappingThere are many varieties of mechanisms that translate virtual addresses to memoryaddresses. They depend on whether objects are stored as fixed-size pages or variablesizesegments, whether each segment is divided into pages, and whether objects areindividually protectable and sharable.

Autopoiesis in Virtual Organizations  

Directory of Open Access Journals (Sweden)

Full Text Available Virtual organizations continuously gain popularity because of the benefits created by them. Generally, they are defined as temporal adhocracies, project oriented, knowledge-based network organizations. The goal of this paper is to present the hypothesis that knowledge system developed by virtual organization is an autopoietic system. The term “autopoiesis” was introduced by Maturana for self-productive systems. In this paper, Wikipedia is described as an example of an autopoietic system. The first part of the paper covers discussion on virtual organizations. Next, autopoiesis’ interpretations are delivered and the value of autopoiesis for governance of virtual organizations is presented. The last parts of the work comprise short presentation of Wikipedia, its principles and conclusions of Wikipedia as an autopoietic system.

Virtual Class Support at the Virtual Machine Level  

DEFF Research Database (Denmark)

This paper describes how virtual classes can be supported in a virtual machine.  Main-stream virtual machines such as the Java Virtual Machine and the .NET platform dominate the world today, and many languages are being executed on these virtual machines even though their embodied design choices conflict with the design choices of the virtual machine.  For instance, there is a non-trivial mismatch between the main-stream virtual machines mentioned above and dynamically typed languages.  One language concept that creates an even greater mismatch is virtual classes, in particular because fully general support for virtual classes requires generation of new classes at run-time by mixin composition.  Languages like CaesarJ and ObjectTeams can express virtual classes restricted to the subset that does not require run-time generation of classes, because of the restrictions imposed by the Java Virtual Machine. We have chosen to support virtual classes by implementing a specialized virtual machine, and this paper describes how this virtual machine supports virtual classes with full generality.

Development of Networked Virtual Experiment System Based on Virtual Campus  

Directory of Open Access Journals (Sweden)

Full Text Available China’s higher education has been going through a period of rapid expansion in undergraduate population,and this means a much heavier demand on teaching resources such as laboratories, experiments, teaching staff,etc., which cannot possibly be made available all of a sudden.To deal with this situation, we found virtual reality (VR) technology very helpful. Virtual reality (VR) has found many applications in education; and the resources of virtual education such as virtual campus, virtual laboratory etc. are used more and more widely, especially in the field of higher education. But so far virtual campus was mainly regarded as a means of image exhibition, and virtual laboratories were no more than 2D display of experimental processes and equipments. To make better use of these resources, this paper puts forward the concept of networked virtual experiment systems based on virtual campus by combining the virtual laboratory and virtual campus with the technique of LAN (Local area network), and establishes its theoretical model. Finally, a networked virtual experiment system based on virtual campus is developed using VRML and 3DSMAX. Networked virtual experiment system based on virtual campus has a promising future for various applications in higher education.

Simultaneously, for many reasons injuries due to wearing contact lenses are increasing. In order to correct this discrepancy, information on contact lenses and practical experience with them must be substantially increased from a medical perspective. This review article deals with the most important aspects for prevention of complications, i.e. contact lens hygiene.

Body dissatisfaction and perceived sociocultural pressures: gender and age differences/ Insatisfacción corporal y presión sociocultural percibida: diferencias asociadas al sexo y a la edad  

Scientific Electronic Library Online (English)

Full Text Available Abstract in spanish Despierta gran interés teórico y social en nuestros días la identificación y medida de los factores que contribuyen al desarrollo de alteraciones de la imagen corporal y más concretamente al desarrollo de la insatisfacción corporal. El prototipo femenino de belleza dominante desde hace tres décadas en nuestra cultura propone una delgadez tan extrema que resulta no sólo inalcanzable, sino además muy poco saludable. El ideal masculino de belleza, por otro lado, dem (more) anda un cuerpo delgado, pero musculado, y éste ha adquirido gran importancia, por lo que con frecuencia se adoptan, a fin de mejorar la propia imagen, numerosas conductas peligrosas para la salud, como el consumo de esteroides, efedrina y dietas alimentarias dañinas. La imagen corporal, conformada por las autopercepciones físicas de cada persona, ha sido objeto de numerosas investigaciones durante las últimas décadas en relación con rasgos psicológicos tan importantes como la autoestima, la depresión, la ansiedad o los trastornos alimentarios y, muy en especial, con la insatisfacción corporal. Está comprobado que, en general, las mujeres manifiestan mayor insatisfacción corporal que los hombres en todas las épocas de su vida, desde la preadolescencia hasta la tercera edad, si bien las diferencias de sexo en la edad adulta y en la tercera edad son menores que en la adolescencia. Por otro lado, aun cuando la insatisfacción de las mujeres con su cuerpo tiende a mantenerse estable a lo largo de todo el ciclo vital, es digno de señalar que la importancia conferida a la apariencia física y, más en concreto, al tamaño y peso corporal, decrece con la edad. La presión sociocultural percibida aparece como principal causa de la insatisfacción corporal. Desde el enfoque sociocultural se señala, en concreto, a los medios masivos de comunicación, al entorno social próximo y a la familia como los tres elementos clave de dicha presión: cuanto más altos son los niveles de presión percibida con respecto a una imagen corporal idealizada, más se incrementa la preocupación por la imagen y por las estrategias de cambio corporal. La investigación previa ha prestado considerable atención a las diferencias de sexo y de edad en cuanto a la insatisfacción corporal, pero se echan en falta: a) conocimientos más precisos sobre la insatisfacción corporal de los hombres; b) una perspectiva comparativa de las diferencias de sexo tanto en insatisfacción corporal como en presión percibida a lo largo de las distintas etapas del ciclo vital; c) mayor información sobre las variaciones interpersonales en la relación entre la insatisfacción corporal y la presión sociocultural percibida, y d) una mejor comprensión de la naturaleza de las influencias socioculturales. Esta investigación trata de contribuir a la superación de estas carencias planteándose las siguientes hipótesis: 1) La insatisfacción corporal guarda estrecha relación con la presión sociocultural percibida; 2) las mujeres participantes, en todos los grupos de edad, muestran más insatisfacción corporal e indican sentirse más influidas por factores socioculturales que los hombres; 3) las diferencias de sexo (tanto en insatisfacción corporal como en presión sociocultural percibida) son mayores en los grupos de menor edad que en los de más edad; 4) el sexo resulta ser un mejor predictor de la insatisfacción corporal y de los influjos socioculturales percibidos que la edad. Participaron en el estudio 1259 personas: 627 adolescentes, 271 adultos jóvenes, 248 adultos y 112 sujetos mayores de 55 años, quienes respondieron el Eating Disorders Inventory-2 (EDI-2), de Garner, que permite identificar la insatisfacción corporal, así como el Cuestionario de Influencias sobre el Modelo Estético Corporal (CIMEC), de Toro, Salamero y Martínez-Mallén. Los resultados obtenidos proporcionan una visión más completa que la hasta ahora disponible acerca de las relaciones entre la insatisfacción corporal y la presión sociocultural percibida en l

Com base na abordagem sociocultural construtivista, o estudo analisa a interação de fatores socioculturais com a participação ativa do indivíduo, destacando a unidade cognição-afeto. Os processos inter (more) ativos atuam como mobilizadores da construção do conhecimento ao longo de convergências e divergências nas interações, especialmente nas negociações quanto aos objetivos e desenvolvimento de atividades pedagógicas. Duas turmas de segunda série do ensino fundamental foram investigadas, sendo destacados os resultados de análises microgenéticas das interações, que apontaram para crenças e estratégias comunicativas e metacomunicativas que podem favorecer ou dificultar o processo de ensino-aprendizagem. A conclusão aponta para o fato dos processos de significação estarem apoiados na metacomunicação e na unidade cognição-afeto, que direcionam as possibilidades de aprendizagem. Abstract in english School failure consists of a persistent problem in our educational system. This paper aims at contributing to understand the issue by presenting and theoretically discussing empirical data concerning the dynamics of teacher-students interactions. We draw our analysis on a constructivist sociocultural theoretical framework, which stresses the interactions between sociocultural factors and human agency, claiming for the unison, intertwined nature of affect and cognition. In (more) teractive processes lie at the basis of knowledge construction, which takes place along convergent and divergent interaction frames, particularly during negotiations about goals and rules for educational activities. Two second-grade classrooms were investigated, the results of microgenetic analysis being especially highlighted and discussed. We show how communicative and metacommunicative strategies, together with teacher beliefs, may promote or inhibit teaching-learning processes. We conclude by discussing how meaning construction processes are profoundly intermingled with the affective-cognitive dimension of human development, and how it may decisively contribute to learning possibilities.

Los objetivos de la investigación se han centrado en analizar algunos aspectos de la adecuación sociolingüística y sociocultural de los alumnos, además de la relación entre la adecuación y el grado de formación (nivel de estudios del español). Nos interesa también observar en qué grado y en qué niveles los alumnos tienden a trasladar a la lengua y la cultura meta pautas de conducta de su propia cultura. Pretendemos fomentar la concienciación sobre la importancia de la adecuación intercultural, pues partimos del supuesto de que se debe enseñar la cultura de una lengua de manera progresiva en todos los niveles, planificando los objetivos y los contenidos y aumentando el grado de dificultad en función del nivel de competencia lingüística y sin perjudicar al resto de las competencias. Abstract in english This paper approaches the issue of adequacy as a component of sociolinguistic, sociocultural and intercultural competence in the learning of Spanish as a foreign language. To accomplish this aim, we carry out a quantitative statistical type of research with the software SPSS 17 (Statistical Product and Service Solutions), in which we apply a descriptive and inferential analysis. The instrument used is a questionnaire and the participants are 59 Bulgarian students who stud (more) y Spanish as a foreign language in a non-immersion context. The levels of the participants are B1, C1 and C2. It is our purpose to analyse some aspects concerning the sociolinguistic and sociocultural adequacy of students, amongst them the relation between adequacy and level of Spanish of the participants. Likewise, we pay attention to the degree in which the students tend to transfer to the target language and culture patterns pertaining to their own culture. We seek to raise awareness about the importance of intercultural adequacy, because we believe that culture of a foreign language must be taught progressively in all levels. Objectives and contents need to be planned carefully, and the degree of complexity must increase according to the linguistic competence of students, without letting aside other competences.

Contact and near-contact binary systems. 4. RT Scl and AQ Tuc  

Energy Technology Data Exchange (ETDEWEB)

Reticon spectroscopic observations are presented for the short-period eclipsing binary systems RT Scl and AQ Tuc. Analysis of these data together with new analyses of previously published light curves show that RT Scl is composed of a main-sequence primary component, virtually in contact with its Roche lobe, and a detached secondary component which is approx. 40 per cent larger than expected for its mass. The system AQ Tuc, which has the same total mass and specific orbital angular momentum as RT Scl, is confirmed to be an A-type WUMa contact system.

Real-Time Control of an Interactive Impulsive Virtual Prosthesis.  

UK PubMed Central (United Kingdom)

An interactive virtual dynamic environment for testing control strategies for neural machine interfacing with artificial limbs offers several advantages. The virtual environment is low-cost, easily configured and offers a wealth of data for post-hoc analysis compared with real physical prostheses and robots. For use with prosthetics and research involving amputee subjects it allows the valuable time with the subject to be spent in experiments rather than fixing hardware issues. The usefulness of the virtual environment increases as the realism of the environment increases. Most tasks performed with limbs require interactions with objects in the environment. To simulate these tasks the dynamics of frictional contact, in addition to inertial limb dynamics must be modeled. Here subjects demonstrate real-time control of an eight degree of freedom virtual prosthesis while performing an interactive box-and-blocks task. With practice, four non-amputee subjects and one shoulder disarticulation subject were able to successfully transfer blocks in the virtual environment at an average rate of just under two blocks per minute. The virtual environment is configurable in terms of the virtual arm design, control strategy, and task.

Virtual Arbitrage Pricing Theory  

UK PubMed Central (United Kingdom)

We generalize the Arbitrage Pricing Theory (APT) to include the contributionof virtual arbitrage opportunities. We model the arbitrage return by astochastic process. The latter is incorporated in the APT framework to calculatethe correction to the APT due to the virtual arbitrage opportunities. Theresulting relations reduce to the APT for an infinitely fast market reaction or inthe case where the virtual arbitrage is absent. Corrections to the Capital AssetPricing Model (CAPM) are also derived.1 IntroductionAlong with the Capital Asset Pricing Model (CAPM) [1, 2, 3] the Arbitrage PricingTheory (APT) [4] is a standard model for determining the expected rate of return onindividual stocks and on a portfolio of stocks [5]. In contrast to the CAPM, the APTdoes not rely on any assumptions about utility functions or the assumption that agentsconsider only the mean and variance of possible portfolios. Taking into account criticalremarks about the expected utility approach to the ...

Virtual-World Naturalism  

Directory of Open Access Journals (Sweden)

Full Text Available Sometimes a player will stray from the path described by a game, moving into new spaces, developing new possible modes of interaction, and often discovering the rougher edges of the game world, where physics models break down, textures become incongruous, and the pieces don’t quite fit together. Gameplay that seeks out these spaces and these phenomena, that searches for such clues to the underlying construction of the virtual environment, is a kind of virtual-world naturalism, at once a return to an investigative urge that has been subsumed to the exhaustive mapping and description of the real world and a form of resistance to the very idea of pre-defined paths of action, of externally imposed limits, in virtual worlds as well as in our own.

A VIRTUAL OPERATING SYSTEM  

Energy Technology Data Exchange (ETDEWEB)

Significant progress toward disentangling computing environments from their under lying operating systern has been made. An approach is presented that achieves inter-system uniformity at all three levels of user interface - virtual machine, utilities, and command language. Under specifiable conditions, complete uniformity is achievable without disturbing the underlying operating system. The approach permits accurate computation of the cost to move both people and software to a new system. The cost of moving people is zero, and the cost of moving software is equal to the cost of implementing a virtual machine. Efficiency is achieved through optimization of the primitive functions.

Ramadan Fasting and Competitive Sports: Psychological Adaptation within Socio-cultural Context  

Directory of Open Access Journals (Sweden)

Full Text Available The article examines the influence of socio-cultural practices of Ramadan fasting in competitive sports and adaptation pathway of the athletes. The study describes how the socio-cultural context acts as the social “panopticon” and explains the adaptation pathways among Muslim archers. Foucauldian concept explains individual actions and behaviors within social and cultural settings, and adaptation pathways during Ramadan fasting. Eleven elite Malaysian Muslim archers participated in an open ended interview to identify individual experiences of competing in high level sports while engaging in Ramadan fasting. Relevant quotes were extracted to identify means and methods leading to a pathway toward adaptation. The inductively identified pathway viz. understanding of the context, control and adjustment, willpower and self enhancement, belonging and gravitating, trust and support culminates in the dimension of adaptation. The study highlights how cultural and societal influences have a bearing on actions, behaviors, and decisions of competitive athletes.

Traditional Mende Society in Sierra Leone: a sociocultural basis for a quantitative research study.  

UK PubMed Central (United Kingdom)

Traditional Birth Attendants (TBAs) deliver more than 85% of the infants born in rural Sierra Leone. These midwives, who learn their skills from practice or a predecessor, are powerful women in the pervasive, secret Sande Society. Formal training programs have been established to strengthen the maternal and infant practices of these TBAs. Designing and implementing a quantitative research study to examine the effectiveness of two methods of TBA training required a strong sociocultural basis. The study was undertaken in a predominantly Mende ethnic area of Sierra Leone. I describe the significant ways in which the values and traditions of the Mende influenced the choice of research methods. Finally, I present critical questions researchers should ask to design a study that fits with the sociocultural fabric of their target population.

Socio-cultural, environmental and behavioural determinants of obesity in black South African women.  

UK PubMed Central (United Kingdom)

South Africa (SA) is undergoing a rapid epidemiological transition and has the highest prevalence of obesity in sub-Saharan Africa (SSA), with black women being the most affected (obesity prevalence 31.8%). Although genetic factors are important, socio-cultural, environmental and behavioural factors, as well as the influence of socio-economic status, more likely explain the high prevalence of obesity in black SA women. This review examines these determinants in black SA women, and compares them to their white counterparts, black SA men, and where appropriate, to women from SSA. Specifically this review focuses on environmental factors influencing obesity, the influence of urbanisation, as well as the interaction with socio-cultural and socio-economic factors. In addition, the role of maternal and early life factors and cultural aspects relating to body image are discussed. This information can be used to guide public health interventions aimed at reducing obesity in black SA women.

The human body on Exhibit: promoting socio-cultural mediations in a science museum  

Directory of Open Access Journals (Sweden)

Full Text Available This paper discusses three mediation concept approaches and, consequently, three facets of mediator action. The approaches presented start with a bibliographical review of the concept of mediation present in education and scientific communication studies. These approaches serve as a basis for interpreting a semi-directive interview with the director of the Museum of Morphological Sciences of the Federal University of Minas Gerais (UFMG). They also help us reflect on the complexity of organizing the objectives of a museum action that takes into account the transformational role of the meaning of objects in interaction with different socio-cultural subjects. In conclusion, the museum's purpose in organizing a museum action using socio-cultural mediation approach and with the mediator as a passeur libre among exhibit objects and visitors is highlighted.

Assessing the sociocultural impacts of emerging molecular technologies for the early diagnosis of Alzheimer's disease.  

UK PubMed Central (United Kingdom)

Novel technologies for early diagnosis of Alzheimer's disease (AD) will impact the way society views and deals with AD and ageing. However, such "sociocultural" impacts are hardly acknowledged in standard approaches of technology assessment. In this paper, we outline three steps to assess such broader impacts. First, conceptual analysis of the ideas underlying technological developments shows how these technologies redraw the boundary between Alzheimer's disease and normal ageing and between biological and social approaches of ageing. Second, imaginative scenarios are designed depicting different possible futures of AD diagnosis and societal ways to deal with ageing and the aged. Third, such scenarios enable deliberation on the sociocultural impact of AD diagnostic technologies among a broad set of stakeholders. An early, broad, and democratic assessment of innovations in diagnostics of AD is a valuable addition to established forms of technology assessment.

In the light of the Rare Earth hypothesis, it seems that advanced life is exceedingly rare in the universe. Also, if there does exist some Extraterrestrial civilizations then still achieving Contact is extremely difficult as the very nature of the universe discourages Contact. It's as if there is a Cosmic Contact Censorship in place.

Socio-cultural challenges to sexual health education for female adolescents in Iran  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Despite clear reasons for necessity of sexual health education for adolescents, it is a contested issue and has faced challenges in most cultures. Providing sexual education for non-married adolescents is culturally unacceptable in most Muslim societies. Objective: This qualitative study addressed socio-cultural challenges to sexual health education for female adolescents in Iran. Materials and Methods: Qualitative data from female adolescents (14-18 yr), mothers, teachers, authorities in health and education organizations, health care providers and clergies were collected in two large cities of Iran including Mashhad and Ahvaz through focus group discussions and individual in-depth interviews. Data were analyzed using conventional qualitative content analysis with MAXqda software. Results: Our results revealed that the main socio-cultural challenges to sexual health education for adolescents in Iran are affected by taboos surrounding sexuality. The emergent categories were: denial of premarital sex, social concern about negative impacts of sexual education, perceived stigma and embarrassment, reluctance to discuss sexual issues in public, sexual discussion as a socio-cultural taboo, lack of advocacy and legal support, intergenerational gap, religious uncertainties, and imitating non-Islamic patterns of education. Conclusion: It seems that cultural resistances are more important than religious prohibitions, and affect more the nature and content of sexual health education. However, despite existence of salient socio-cultural doubtful issues about sexual health education for adolescents, the emerging challenges are manageable to some extent. It is hoped that the acceptability of sexual health education for adolescents could be promoted through overcoming the cultural taboos and barriers as major obstacles.

Socio-Cultural and Attitudinal Study of Selected Yoruba Taboos in South West Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available This study presents a socio-cultural description of some Yoruba taboos which are an integral part of culture and youths’ attitude towards these taboos. The theoretical frame work for the study is based on Vygotskian’s sociocultural approach which holds that higher order functions develop out of social interaction. In other words, cultural development of an individual, especially the young ones, depends largely on social interactions with elders. Some socio-cultural factors like age, sex and education are the variables employed in the analysis. Data is gathered from interviewing students and staff of Redeemer’s University, Mowe, Ogun state and Obafemi Awolowo University, Ile-Ife, Osun state in the South Western part of Nigeria. Books and documents are also consulted. In the process of describing some selected Yoruba taboos, it is discovered that: (a) the language of a particular society is an integral part of its culture, (b) many of the taboos have been taken over by Christianity and technology (c) youths have a laissez-faire attitude as their belief in taboos is fast disappearing because parents and guardians do not educate children in these acts any more. It is concluded that for the Yoruba culture to be saved from imminent extinction, parents must expose the young ones to cultural beliefs and ensure that they speak the language. This is necessary because internalized culture allows people to respond in appropriate ways to the norms of the society or community in which they live.Key words: Socio-cultural; Yoruba taboos; Society’s attitude

The influence of socio-cultural background and product value in usability testing.  

UK PubMed Central (United Kingdom)

This article examines the influence of socio-cultural background and product value on different outcomes of usability tests. A study was conducted in two different socio-cultural regions, Switzerland and East Germany, which differed in a number of aspects (e.g. economic power, price sensitivity and culture). Product value (high vs. low) was varied by manipulating the price of the product. Sixty-four test participants were asked to carry out five typical user tasks in the context of coffee machine usage, measuring performance, perceived usability, and emotion. The results showed that in Switzerland, high-value products were rated higher in usability than low-value products whereas in East Germany, high-value products were evaluated lower in usability. A similar interaction effect of socio-cultural background and product value was observed for user emotion. Implications are that the outcomes of usability tests do not allow for a simple transfer across cultures and that the mediating influence of perceived product value needs to be taken into consideration.

Socio-cultural barriers to the development of a sustainable energy system - the case of hydrogen  

Energy Technology Data Exchange (ETDEWEB)

Any transition to a more sustainable energy system, radically reducing greenhouse gas emissions, is bound to run in to a host of different barriers - technological and economic, but also socio-cultural. This will also be the case for any large-scale application of hydrogen as energy carrier, especially if the system is going to be based on renewable energy sources. The aim of these research notes is to review and discuss major socio-cultural barriers to new forms of energy supply in general and to hydrogen specifically. Reaching sufficient reductions in greenhouse gas emissions may require more than large-scale dissemination of renewable energy sources. Also reductions or moderations in energy demand may be necessary. Hence, a central point in the research note is to consider not only socio-cultural obstacles for changing technologies in energy production, distribution and consumption but also obstacles for changing the scale of energy consumption, i.e. moderating the growth in how much energy is consumed or even reducing consumption volumes.

UK PubMed Central (United Kingdom)

BACKGROUND: The aims of this study were to evaluate postoperative quality of life in patients who have had resections of tongue cancer and reconstruction by flaps and to collect information about their sociocultural situation. METHODS: In this cross-sectional study, patients with primary tongue cancer treated with total and subtotal tongue resection in the First Affiliated Hospital of Zhengzhou University, between July 2008 and October 2011, were included. Quality of life was assessed by the 14-item Oral Health Impact Profile and the Medical Outcomes Study-Short Form 36 questionnaires 12 months postoperatively. Furthermore, a questionnaire about the sociocultural background of the patients was applied. RESULTS: Forty-six of the 62 questionnaires were returned (74.19%). In the Medical Outcomes Study-Short Form 36, the best-scoring domain was bodily pain, whereas the lowest scores were for social functioning and vitality. In the 14-item Oral Health Impact Profile, the lowest-scoring domain was psychological disability, followed by psychological discomfort and social disability. CONCLUSIONS: The postoperative quality of life in our patients was significantly influenced by tongue resection. This should be considered for surgical planning. The sociocultural data showed a rather low education level and life standard level for the majority of the patients.

Body dissatisfaction, engagement in body change behaviors and sociocultural influences on body image among Chinese adolescents.  

UK PubMed Central (United Kingdom)

Body dissatisfaction and body image disorders are becoming increasingly prevalent in developing non-Western countries such as China, but there is a lack of research examining the sociocultural factors that in other contexts have been associated with these problems. The current study investigated body dissatisfaction, engagement in body change behaviors, and sociocultural pressures on body image, and the relationships between these variables among 517 adolescent males (N=219) and females (N=298) in China. Females reported greater body dissatisfaction than males, and males reported using strategies to increase their muscle bulk more often than females. Males reported pressure from a variety of sociocultural sources to increase their muscles or weight, while females reported pressure from the media to lose weight. For males body dissatisfaction was predicted by pressure from peers to increase their muscle bulk, while for females pressure to lose weight from peers, adult relatives, and the media was likely to increase body dissatisfaction. Pressure from the media and adult relatives was also predictive of body change behaviors in both males and females. The findings are discussed in relation to previous research in both Western and non-Western contexts.

Sociocultural theory and reading comprehension: The scaffolding of readers in an EFL context  

Directory of Open Access Journals (Sweden)

Full Text Available The focus of the present study was to investigate the possible effects of sociocultural-based teaching techniques on EFL learners reading comprehension. The basic purpose was to clarify how learners reading comprehension and strategy use could be affected by the types of teaching techniques and how high and low proficiency learners profited from the intervention. Iranian EFL students were used as the participants of the study. A NELSON language proficiency test, a researcher-made reading comprehension test and a reading strategy questionnaire (adopted from Phakiti, 2006) were used as data collection instruments. The results showed that the sociocultural teaching techniques leads to better reading comprehension and reading strategy use for EFL learners. Also shown that proficiency factor played a determining role in reading comprehension development of the two groups of this study and that the low proficiency learners, especially in sociocultural group, outperformed the high proficiency learners. However, the interaction effect between proficiency factor and teaching method was non-significant for reading strategy use; leading to the conclusion that strategy use of the learners was not affected by their proficiency level. This indicates that the patterns of cognitive and metacognitive strategy scores are similar for students of low and high proficiency.

Virtual reality for emergency training  

Energy Technology Data Exchange (ETDEWEB)

Virtual reality is a sequence of scenes generated by a computer as a response to the five different senses. These senses are sight, sound, taste, touch, smell. Other senses that can be used in virtual reality include balance, pheromonal, and immunological senses. Many application areas include: leisure and entertainment, medicine, architecture, engineering, manufacturing, and training. Virtual reality is especially important when it is used for emergency training and management of natural disasters including earthquakes, floods, tornados and other situations which are hard to emulate. Classical training methods for these extraordinary environments lack the realistic surroundings that virtual reality can provide. In order for virtual reality to be a successful training tool the design needs to include certain aspects; such as how real virtual reality should be and how much fixed cost is entailed in setting up the virtual reality trainer. There are also pricing questions regarding the price per training session on virtual reality trainer, and the appropriate training time length(s).

Virtual Reality in Psychology  

Directory of Open Access Journals (Sweden)

Full Text Available The benefits of using virtual environments (VEs) in psychology arise from the fact that movements in virtual space, and accompanying perceptual changes, are treated by the brain in much the same way as those in equivalent real space. The research benefits of using VEs, in areas of psychology such as spatial learning and cognition, include interface flexibility, the reproducibility of virtual experience, and the opportunity for on-line monitoring of performance. Applications of VEs are many and varied, but are especially beneficial where experience can be tailored via augmentation, and where dangerous training situations can be avoided. The use of programmable agents has great future potential in relation to training and interpersonal skill development, also perhaps in clinical diagnosis and therapy. Progress in VE usage in psychological education is limited by cost and availability, though VEs are being used increasingly in classroom and laboratory teaching exercises. Virtual Reality was said to be “an answer waiting for a question”, but questions are being recognized, so that applications of VEs within the behavioural sciences are likely to multiply.

Temperature-aware virtual machine in Para Virtualization Cloud Environment  

Directory of Open Access Journals (Sweden)

Full Text Available This paper describes the Para virtualization which involves modi?cation of a guest operating system (OS). Today this method is only supported for open source operating systems, limiting its applicability. However, par virtualization provides higher performance than full virtualization in performance because it does not need to trap and translate every OS call. Here temperature aware virtual machine can be implemented in Para virtualized cloud environment and provides the details of hardware and software tools which can be used in implementation. At last to demonstrate feasibility of our approach from a performance perspective we have shown quantitative results.

Endolaryngeal contact pressures.  

UK PubMed Central (United Kingdom)

In this work, we present a new method for in vivo endolaryngeal contact pressure measurement with a miniature pressure transducer. Using this methodology, contact pressures can be measured during videoendoscopy at different locations between the artyenoids and also at various locations along the membranous vocal folds. Twenty adults with organic and functional voice disorders and two vocally healthy adults participated as subjects. Endolaryngeal contact pressure measures were made during a series of phonatory tasks varying pitch, loudness, and phonatory onset and offset. Measures were also made during nonphonatory tasks, including throat clearing, coughing, Valsalva maneuvres, and gagging. The most remarkable findings were: (1) interarytenoid contact pressures were considerably greater than intraglottal contact pressures; (2) interarytenoid contact pressures were greater for lower than higher pitches; (3) both interarytenoid and intraglottal contact pressures were remarkably large during hard glottal attack; and (4) overall, the largest endolaryngeal pressures were recorded between the arytenoids, during a thoracic fixation maneuver and during gag reflex.

An Investigation of Communication in Virtual High Schools  

Directory of Open Access Journals (Sweden)

Full Text Available Virtual schooling is an increasing trend for secondary education. Research of the communication practices in virtual schools has provided a myriad of suggestions for virtual school policies. The purpose of this qualitative study was to investigate the activities and processes involved in the daily rituals of virtual school teachers and learners with the goal of determining how regular phone calls by teachers contributed to the work habits of students. Eight virtual teachers were observed attempting to contact more than 60 struggling learners. Phone conversations with 12 of these learners showed that teachers repeatedly attempted to help them. Eleven students were interviewed and indicated preferences for written communications. Ten additional teachers who were interviewed emphasized the difficulty they had in reaching students by phone and the lack of student responses to phone-call attempts. The teachers in the study provided additional data regarding their regular communication patterns. Archival records from more than 100 contact attempts showed that approximately 20% of the students responded to teacher phone calls and less than half of these students completed the work requested. The interview data revealed that teachers believe written communications or multiple forms of communication may be more effective than regular phone calls. Future research should extend current research by expanding on sample size and investigating alternate methods of communication. Further investigation of learner responses to phone calls and of nonresponsive students could add to this data.

Selected sociocultural correlates of physical activity among African-American adults.  

UK PubMed Central (United Kingdom)

OBJECTIVE: Previous studies have identified several factors to be associated with physical activity (PA) among African-Americans, e.g., demographic and health-related characteristics. Formative studies suggest a link between sociocultural factors and PA among ethnic minorities; yet, it is unclear whether these factors play a role in PA among African-Americans. This paper explores the association of selected sociocultural characteristics with self-reported PA by gender among African-American adults, taking into account demographic and health-related characteristics. DESIGN: Data from the baseline survey of a colorectal cancer communication intervention trial were used. Participants included 446 African-American men and women, aged 45-75 years. Self-report data were collected on demographics, health-related characteristics, selected sociocultural constructs (e.g., ethnic identity, religiosity, collectivism, and medical mistrust), and PA. PA was categorized as meeting or not meeting recommended levels; recommended levels were defined as participating in vigorous PA for 20 minutes/day for at least three days/week or moderate PA for 30 minutes/day for at least five days/week or a minimum of 600 MET-minutes/week in at least five days. Chi-square and multivariate logistic regression models were used to characterize the association between the selected sociocultural constructs and PA among men and women, after adjusting for demographic and health-related characteristics. RESULTS: Most participants reported some PA but only 59% were found to be meeting recommended levels. Univariate analyses revealed that high collectivist attitudes were associated with meeting recommended PA (OR = 1.74), particularly for women (OR = 1.81). In multivariate analyses, high collectivist attitudes were significantly associated with meeting PA recommendations among men (OR = 1.87); while high religiosity and high collectivism were significant among women (OR = 1.87 and 1.85, respectively). CONCLUSIONS: Few of the selected sociocultural characteristics were found to be associated with meeting recommended PA levels. Further study is needed to understand the association of these characteristics with PA among African-Americans.

Advanced virtual magnetic resonance imaging (MRI) techniques in neurovascular conflict: bidimensional image fusion and virtual cisternography.  

UK PubMed Central (United Kingdom)

PURPOSE: The aim of this study was to evaluate the advantages and limits of virtual magnetic resonance techniques in planning surgery for microvascular decompression in patients with neurovascular conflict. MATERIALS AND METHODS: Between December 2010 and December 2011, we prospectively observed 32 patients (30 with trigeminal neuralgia and two with hemifacial spasm), with a suspected clinical diagnosis of neurovascular conflict. To assess the contact between nerve and vessel, magnetic resonance imaging (MRI) by three-dimensional (3D) constructive interference in steady state (CISS) and high-resolution MR angiography (MRA) were performed in all cases. Moreover, we performed presurgical simulation of microvascular decompression using MR two-dimensional image fusion and virtual cisternography. The neuroradiological findings were compared with the surgical findings. RESULTS: In all cases, we demonstrated the anatomical relations between cranial nerves and offending vessels with an optimal correlation between radiological and surgical patterns. CONCLUSIONS: Advanced virtual MRI techniques, such as image fusion and virtual cisternography, are able to depict the complex anatomical relationships between neural and vascular structures within the cisternal spaces of the skull base. These techniques can be considered an optimal presurgical tool to support traditional MRI evaluation of this region.

Applied virtual reality  

International Nuclear Information System (INIS)

An early experience in deploying a manipulator to the Irradiated Fuel Dismantling Cell at Torness Power Station, quickly highlighted that special visualisation techniques were required to achieve a successful deployment and reduce plant system down time. This visualisation was later realised through the IGRIP software pakcage operating on a Silicon Graphics computing engine, which provides a 'Non-Immersive' Virtual Reality environment. Within this environment, models of the Irradiated Fuel Dismantling cell were generated along with a model of the manipulator, allowing manipulator deployment to the Irradiated Fuel Dismantling Cell be modelled. It is estimated that the first use of this new environment provided a significant saving to Scottish Nuclear in potential lost output. The use of this virtual reality environment is currently being extended into the design and deployment of a new manipulator for Torness in vessel inspection, the Boiler Inspection Manipulator.

Theft of Virtual Property — Towards Security Requirements for Virtual Worlds  

Science.gov (United States)

The article is focused to introduce the topic of information technology security for Virtual Worlds to a security experts’ audience. Virtual Worlds are Web 2.0 applications where the users cruise through the world with their individually shaped avatars to find either amusement, challenges or the next best business deal. People do invest a lot of time but beyond they invest in buying virtual assets like fantasy witcheries, wepaons, armour, houses, clothes,...etc with the power of real world money. Although it is called “virtual” (which is often put on the same level as “not existent”) there is a real value behind it. In November 2007 dutch police arrested a seventeen years old teenager who was suspicted to have stolen virtual items in a Virtual World called Habbo Hotel [Reuters07]. In order to successfully provide security mechanisms into Virtual Worlds it is necessarry to fully understand the domain for which the security mechansims are defined. As Virtual Worlds must be clasified into the domain of Social Software the article starts with an overview of how to understand Web 2.0 and gives a short introduction to Virtual Worlds. The article then provides a consideration of assets of Virtual Worlds participants, describes how these assets can be threatened and gives an overview of appopriate security requirements and completes with an outlook of possible countermeasures.

Virtual Quantum Subsystems  

Energy Technology Data Exchange (ETDEWEB)

The physical resources available to access and manipulate the degrees of freedom of a quantum system define the set A of operationally relevant observables. The algebraic structure of A selects a preferred tensor product structure, i.e., a partition into subsystems. The notion of compoundness for quantum systems is accordingly relativized. Universal control over virtual subsystems can be achieved by using quantum noncommutative holonomies

Virtual nuclear weapons  

Energy Technology Data Exchange (ETDEWEB)

The term virtual nuclear weapons proliferation and arsenals, as opposed to actual weapons and arsenals, has entered in recent years the American lexicon of nuclear strategy, arms control, and nonproliferation. While the term seems to have an intuitive appeal, largely due to its cyberspace imagery, its current use is still vague and loose. The author believes, however, that if the term is clearly delineated, it might offer a promising approach to conceptualizing certain current problems of proliferation. The first use is in a reference to an old problem that has resurfaced recently: the problem of growing availability of weapon-usable nuclear materials in civilian nuclear programs along with materials made `excess` to defense needs by current arms reduction and dismantlement. It is argued that the availability of these vast materials, either by declared nuclear-weapon states or by technologically advanced nonweapon states, makes it possible for those states to rapidly assemble and deploy nuclear weapons. The second use has quite a different set of connotations. It is derived conceptually from the imagery of computer-generated reality. In this use, one thinks of virtual proliferation and arsenals not in terms of the physical hardware required to make the bomb but rather in terms of the knowledge/experience required to design, assemble, and deploy the arsenal. Virtual weapons are a physics reality and cannot be ignored in a world where knowledge, experience, materials, and other requirements to make nuclear weapons are widespread, and where dramatic army reductions and, in some cases, disarmament are realities. These concepts are useful in defining a continuum of virtual capabilities, ranging from those at the low end that derive from general technology diffusion and the existence of nuclear energy programs to those at the high end that involve conscious decisions to develop or maintain militarily significant nuclear-weapon capabilities.

Medical Virtual Public Services  

Directory of Open Access Journals (Sweden)

Full Text Available The healthcare enterprises are very disconnected. This paper intends to propose a solution that will provide citizens, businesses and medical enterprises with improved access to medical virtual public services. Referred medical services are based on existing national medical Web services and which support medically required services provided by physicians and supplementary health care practitioners, laboratory services and diagnostic procedures, clinics and hospitals’ services. Requirements and specific rules of these medical services are considered, and personalization of user preferences will to be supported. The architecture is based on adaptable process management technologies, allowing for virtual services which are dynamically combined from existing national medical services. In this way, a comprehensive workflow process is set up, allowing for service-level agreements, an audit trail and explanation of the process to the end user. The process engine operates on top of a virtual repository, providing a high-level semantic view of information retrieved from heterogeneous information sources, such as national sources of medical services. The system relies on a security framework to ensure all high-level security requirements are met. System’s architecture is business oriented: it focuses on Service Oriented Architecture - SOA concepts, asynchronously combining Web services, Business Process Management – BPM rules and BPEL standards.

Moduli of contact circles  

CERN Document Server

We continue the study of linear families of contact forms on 3-manifolds begun in our paper `Contact geometry and complex surfaces'. The present paper introduces Teichmuller and moduli spaces for so-called taut contact circles. By constructing a developing map for taut contact circles, we show that these geometrically defined deformation spaces are equivalent to certain spaces of representations of the fundamental group in appropriate Lie groups. Furthermore, we relate these deformation spaces to `classical' Teichmuller theory of Riemann surfaces and orbifolds.

Allergic Contact Dermatitis  

Directory of Open Access Journals (Sweden)

Full Text Available Allergic contact dermatitis is the delayed type hypersensitivity reaction to exogenous agents. Allergic contact dermatitis may clinically present acutely after allergen exposure and initial sensitization in a previously sensitized individual. Acute phase is characterized by erythematous, scaly plaques. In severe cases vesiculation and bullae in exposed areas are very characteristic. Repeated or continuous exposure of sensitized individual with allergen result in chronic dermatitis. Lichenification, erythematous plaques, hyperkeratosis and fissuring may develop in chronic patients. Allergic contact dermatitis is very common dermatologic problem in dermatology daily practice. A diagnosis of contact dermatitis requires the careful consideration of patient history, physical examination and patch testing. The knowledge of the clinical features of the skin reactions to various contactans is important to make a correct diagnosis of contact dermatitis. It can be seen in every age, in children textile product, accessories and touch products are common allergens, while in adults allergic contact dermatitis may be related with topical medicaments. The contact pattern of contact dermatitis depends on fashion and local traditions as well. The localization of allergic reaction should be evaluated and patients’ occupation and hobbies should be asked. The purpose of this review is to introduce to our collaques up dated allergic contact dermatitis literatures both in Turkey and in the World.

Sociocultural Characteristics of Psychological Education in the Context of Systemic-Anthropological Approach  

Directory of Open Access Journals (Sweden)

Full Text Available Problem statement: The problem of moving from economic efficiency of the social one in the modern society is actualized. It is pointed out that the methodological basis for the solving questions of psychological education development are considered to be an anthropological psychology as a new scientific branch, which reflects the tendencies of development of psychology now a days. It is shown that there are various points of view on psychological education: self-organization as adaptation, self-organization as self-regulation and self-organization as self-determination. On the basis of these points of view psychology educational opportunities of a human being are considered as an individual life strategy aimed at success. Approach: The possibilities of different sociocultural environments and their contribution to psychological education of a person have been analyzed. The attention has been drawn to the fact, that sociocultural environment is the complex of social conditions of a personâ??s life, that allow to act in accordance with the structure and functions of the environment, choosing from the variety of possibilities those, which can be realized. The question of free choice of possible alternatives and creating of oneâ??s own life story is discussed. Results: The motivation of achievement has qualitative differences depending on character of socio-cultural identity. If socio-cultural identity is positive, motivation of achieving the successes is a general life line. The revealed connection of components of positive functioning and showing the motivation of achievement has been considered in the context of our research as a full, subjective experience, which is of great importance for the person himself, as it is connected to basic human values and such everyday notions as happiness, happy life. When characterized the experience of psychological well-being by a person, it is necessary to mention that it supposes comparison of oneâ?? existence of the norm, sample or ideal. But this norm or sample is in the consciousness of the experiencing person, thus psychological well-being is a kind of self-attitude. Conclusion: The revealed differences allow us to make a conclusion that more opened socio-cultural environment of a large city and personal activity of respondents, define the direction of development, conduce broadening of the axiological and meaningful area. Whereas because of deficiency of forms of socio-cultural environment, students living in a town appear to have different important features of character in comparison with the respondents from a large city. Young peopleâ??s life goes on the basis of earlier stereotypes, according to arrangement activities, which limit personal development. Specifics of formation as possibilities of life self-fulfillment in the system-anthropological context set by our acts as creativity in relation to itself which is determined future-the world of its (human being) of the purposes directing activity in the present.

[Socio-cultural, obstetric and anthropometric characteristics of newborn children of mothers who smoke in Spain].  

UK PubMed Central (United Kingdom)

INTRODUCTION: One in every four women smoke at the beginning of the pregnancy in Spain; of these, 25-50% give up smoking during gestation and most of them smoke again after childbirth. Maternal smoking has harmful effects on babies, such as low birth-weight with its resulting morbidity. The objective of this study is to compare the anthropometric and socio-cultural characteristics between newborns from smoking mother?s and those from non- smoking ones. MATERIALS AND METHODS: Smoking habits and the socio-cultural characteristics were assessed from a sample of 1499 pregnant women, as well as their newborn anthropometric variables of their newborn babies during 2009 in the Aragon region of Spain. RESULTS: In the sample of 1499 pregnant women the prevalence of smoking during pregnancy was 19.6%; among the Spanish women, 23% of them smoked during the gestation compared with only 11% in women from other countries. The smoker mothers were younger and they had a lower educational level than the non smoker ones; however, there were no statistical differences between their anthropometric characteristics. Newborns from smoker women in Aragon had a lower weigh at delivery (3155 vs. 3295 grams: p<.001) and a relative risk of low weight at birth for their gestational age of 2.1 (95% CI: 1.35 - 2.97). The length and the rest of newborn anthropometric variables were also affected. CONCLUSION: The prevalence of smoking during gestation is high in Aragon. The mothers who smoke are younger and have different socio-cultural characteristics compared with non-smoker mothers. Maternal smoking habits have a harmful effect on newborn nutritional status, representing an avoidable risk of low weight at birth.

The Relationship between Socio-cultural Context, Parenting Style, Adolescents’ Learning Style, and Scholastic Achievement  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Regarding the effects of socio-economic factors on child upbringing, and the role of rearing methods on thought, behavior, and academic and social achievements, this study aimed to examine the influence of socio-cultural context on parenting style, academic achievement, and learning style in the city of Tehran. Method: In a descriptive cross-sectional study, 240 eighth grade students (120 males, 120 females) from the southern, central, and northern parts of Tehran were selected using cluster multistage sampling. To assess the socio-cultural background, four demographic factors including place of residence, number of children, parents’ place of birth, and parents’ education were employed. The Parental Authority Questionnaire was used to assess rearing method. Also, learning style was assessed with Kolb’s Learning Style Inventory. Academic achievement was assessed using the grade average of final exams. Results were analyzed using statistical analysis of variance, Scheffe post hoc test, multifactor regression, and Pearson correlation test.Results: The authoritative parenting style was more prevalent in city southern parts. There was positive and significant correlation between authoritative parenting style and higher academic grades. ANOVA showed that the authoritative parenting cultivate theorist learning style. Conclusion: In families residing in Tehran, socio-cultural background is related to child rearing method. Families residing in the southern parts of the city use more authoritarian approaches. Child rearing method is also correlated with learning method and academic achievement of child- ren. Authoritative parenting appeared to cultivate “theorist” learning style and promote better aca- demic achievement.

The influence of sociocultural factors on the eating attitudes of Lebanese and Cypriot students: a cross-cultural study.  

UK PubMed Central (United Kingdom)

BACKGROUND: The present comparative cross-cultural study aimed to explore the relationship between eating behaviour and sociocultural influences with respect to appearance and body image in female university students from two cultural contexts, namely Cyprus and Lebanon. METHODS: The Dutch Eating Behavior questionnaire (DEBQ) and the Perceived Sociocultural Influences on Body Image and Body Change Questionnaire were used to assess sociocultural influences and body image, respectively, in 200 students from each country. RESULTS: The results indicated that the Lebanese students were more likely to engage in emotional and external eating and their body image was impacted to a larger extent by sociocultural agents, including media influences, compared to the Cypriot students. Also, a positive relationship was found between emotional and external eating in both cultures. Finally, sociocultural influences correlated positively with external eating only in the Cypriot sample. CONCLUSIONS: Culture-specific factors, such as the societal values and norms, as well as the Westernisation history of each country, are discussed as underpinnings for the differences found. These findings are significant for understanding the rise of eating pathology in these two cultures and provide evidence for a need to consider cultural environment when designing public health policies addressing the negative aspects of nutrition transition.

Electric contact arcing  

International Nuclear Information System (INIS)

Electrical contacts must function properly in many types of components used in nuclear weapon systems. Design, application, and testing of these components require detailed knowledge of chemical and physical phenomena associated with stockpile storage, stockpile testing, and operation. In the past, investigation of these phenomena has led to significant discoveries on the effects of surface contaminants, friction and wear, and the mechanics of closure on contact performance. A recent investigation of contact arcing phenomena which revealed that, preceding contact closure, arcs may occur at voltages lower than had been previously known is described. This discovery is important, since arcing may damage contacts, and repetitive testing of contacts performed as part of a quality assurance program might produce cumulative damage that would yield misleading life-test data and could prevent proper operation of the contacts at some time in the future. This damage can be avoided by determining the conditions under which arcing occurs, and ensuring that these conditions are avoided in contact testing.

Contact for solar cell  

Energy Technology Data Exchange (ETDEWEB)

A solar cell has a rear electrical contact for the semiconductor body of the cell forming an intersecting pattern which includes rows of contact pads which are parallel to a pair of sides of the body; a set of contact strips which also are parallel to such sides; another set of contact strips which are parallel to another pair of sides of the body perpendicular to the first pair of sides; and yet another set of contact strips which are angularly oriented with respect to both pairs of sides of the body. The contact pattern permits the passage of radiation through the cell which would otherwise decrease efficiency due to heat generation and incorporates additional features designed to balance a desire for transparency to such radiation with a requirement for efficient charge collection along the rear of the cell. The front electrical contact for the semiconductor body forms an intersecting pattern, designed to balance the requirement for the entry of solar radiation into the body with the efficient collection of charges at the front of the solar cell, which is similar in some details to the rear electrical contact but significantly different as to other details.

A Socio-Cultural Model Based on Empirical Data of Cultural and Social Relationship  

DEFF Research Database (Denmark)

The goal of this paper is to integrate culture and social relationship as a computational term in an embodied conversational agent system by employing empirical and theoretical approach. We propose a parameter-based model that predicts nonverbal expressions appropriate for specific cultures in different social relationship. So, first, we introduce the theories of social and cultural characteristics. Then, we did corpus analysis of human interaction of two cultures in two different social situations and extracted empirical data and finally, by integrating socio-cultural characteristics with empirical data, we establish a parameterized network model that generates culture specific non-verbal expressions in different social relationships.

Can sociocultural and historical mechanisms influence the development of borderline personality disorder?  

UK PubMed Central (United Kingdom)

Borderline personality disorder (BPD) is a common and severe clinical problem. While cross-cultural research suggests that this condition can be identified in different societies, indirect evidence suggests that BPD and some of its associated symptoms (suicidality and self-harm) have a higher prevalence in developed countries. If so, sociocultural and historical mechanisms may have influenced the development of the disorder. While the vulnerabilities underlying BPD are broad and nonspecific, specific symptoms can be shaped by culture. The mechanisms involve the influence of a "symptom bank," as well as the role of social contagion. These trends may be related to a decrease in social cohesion and social capital in modern societies.

Perfectionism in Body Dissatisfaction, Sociocultural Influence of the Thinness model and Symptoms of Eating Disorders  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this study was to assess if perfectionism components explained body dissatisfaction (BD), sociocultural influences of aesthetic model (SIAM) and symptoms of eating disorders (ED). The sample comprised 30 women with Bulimia Nervosa (BN), 35 women with Eating Disorder not Otherwise Specified (EDNOS) and 63 women without ED. A regression analysis showed that concern over mistakes (CM) and doubt about actions explained BD and SIAM in the BN sample; while concern over mistakes only explained SIAM in the EDNOS sample. These findings evidence that two perfectionism components contribute to vulnerability of thinness ideal and BD among women, which constitute two important risk factors for ED.

Systemic contact dermatitis.  

UK PubMed Central (United Kingdom)

Systemic contact dermatitis is an inflammatory skin disease that may occur in persons with contact allergy when they are exposed to the hapten orally, transcutaneously, per rectum, intravesically, intravenously, or by inhalation. The most common causes of systemic contact dermatitis are drugs used both topically and systemically. Other causes are ubiquitously occurring haptens, such as the metals nickel, cobalt, gold, and chromate, and aromatic substances such as spices. Avoidance of the offending hapten is the most obvious treatment. For some haptens, such as nickel, diet treatment may be effective. Chelation therapy with disulfiram is another therapeutic option in nickel-allergic patients with systemic contact dermatitis. Hyposensitization therapy has been attempted with some success in systemic contact dermatitis caused by nickel and Parthenium hysterophorus.

Navigation Assistance in Virtual Worlds  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper we report about ongoing research on navigation assistance in virtual environments. Our aim is to contribute to the development of forms of navigation assistance that enable non-professional visitors of a virtual environment to find their way without previous training. The environment used in this re-search is a virtual theatre that models a real world music theatre. This virtual theatre can be used for exploration as well as for transactions and goal-directed search for information. We first present some de-sign principles for navigation assistance in virtual environments and some design criteria for assistance by personal agents. Subsequently we describe how these principles and criteria have been implemented in our experimental virtual theatre environment. Finally we give an overview of future research plans.

Verbal Interactions in Virtual Worlds  

CERN Multimedia

We first discuss respective advantages of language interaction in virtual worlds and of using 3D images in dialogue systems. Then, we describe an example of a verbal interaction system in virtual reality: Ulysse. Ulysse is a conversational agent that helps a user navigate in virtual worlds. It has been designed to be embedded in the representation of a participant of a virtual conference and it responds positively to motion orders. Ulysse navigates the user's viewpoint on his/her behalf in the virtual world. On tests we carried out, we discovered that users, novices as well as experienced ones have difficulties moving in a 3D environment. Agents such as Ulysse enable a user to carry out navigation motions that would have been impossible with classical interaction devices. From the whole Ulysse system, we have stripped off a skeleton architecture that we have ported to VRML, Java, and Prolog. We hope this skeleton helps the design of language applications in virtual worlds.

Virtual factory; Bacharu-fakutori  

Energy Technology Data Exchange (ETDEWEB)

Virtual reality is a matter which CG (computer graphics) and simulation were fused technologically. This technology has been directed naturally toward to designing for products too. These products are called virtual products and contrivances which make up them are called virtual factories. At Boeing Co., in designing of passenger planes, a new system which use a digital mock-up instead of usual mock-up is now developing. In this system, we can walk about in a virtual cabin and touch seats directly by using HMD (head mounted displays) and data gloves. The most dramatic example of virtual products was the repair job on the Hubble space telescope launched in 1990. Those who repair in the space in practice being some spacemen, they succeeded in real repair job owing to rehearsals of assembling which were repeated many times by using virtual products. 3 refs., 10 figs.

Does Language Contact Necessarily Engender Conflict? The Case of Cameroonian Quadrilinguism  

Directory of Open Access Journals (Sweden)

Full Text Available Cameroon proffers a propitious environment for the breeding of interesting linguistic phenomena that attract the curiosity of innumerable researchers. Its rich socio-cultural and linguistic background demonstrate a seemingly harmonious co-existence of two official languages – English and French, a wide spread de facto lingua franca – Pidgin English and a myriad of about 266 Home Languages attest to the complexity inherent here. The co-existence of these languages, like in similar multilingual societies produces language contact situations such as code switching, interference, linguistic borrowing, diglossia, translation, etc., as users interact. This paper assesses language behaviour in such a complex multilingual setting where users adopt varying behavioural patterns leading to the production of interesting linguistic features and patterns worthy of investigation. Following Giles' Accommodation Theory and the descriptive and exploratory approaches, the paper accounts for and paints a vivid picture of the nature of language contact here, the consequences on the different languages and their users. It redefines conflict in relation to the socio-cultural and linguistic realities of this community. Drawing evidence from true-to-life situations, the paper establishes that if contact has to engender conflict, certain socio-cultural, political and linguistic forces related to attitudinal prejudices, unintelligibility, language policies, contextual clues, linguistic hostilities, etc., are likely to be responsible. It concludes with practical remedies like the redefinition of language policies based on the linguistic aspirations of speakers and the reconciliation of linguistic and political independence in order to carefully harness the linguistic resources of this crassly heterogeneous community.

Organization and function of membrane contact sites.  

UK PubMed Central (United Kingdom)

Membrane-bound organelles are a wonderful evolutionary acquisition of the eukaryotic cell, allowing the segregation of sometimes incompatible biochemical reactions into specific compartments with tailored microenvironments. On the flip side, these isolating membranes that crowd the interior of the cell, constitute a hindrance to the diffusion of metabolites and information to all corners of the cell. To ensure coordination of cellular activities, cells use a network of contact sites between the membranes of different organelles. These membrane contact sites (MCSs) are domains where two membranes come to close proximity, typically less than 30nm. Such contacts create microdomains that favor exchange between two organelles. MCSs are established and maintained in durable or transient states by tethering structures, which keep the two membranes in proximity, but fusion between the membranes does not take place. Since the endoplasmic reticulum (ER) is the most extensive cellular membrane network, it is thus not surprising to find the ER involved in most MCSs within the cell. The ER contacts diverse compartments such as mitochondria, lysosomes, lipid droplets, the Golgi apparatus, endosomes and the plasma membrane. In this review, we will focus on the common organizing principles underlying the many MCSs found between the ER and virtually all compartments of the cell, and on how the ER establishes a network of MCSs for the trafficking of vital metabolites and information. This article is part of a Special Issue entitled: Functional and structural diversity of endoplasmic reticulum.

UK PubMed Central (United Kingdom)

We present the design of the Virtual Microscope, a software system employing a client/server architecture to provide a realistic emulation of a high power light microscope. We discuss several technical challenges related to providing the performance necessary to achieve rapid response time, mainly in dealing with the enormous amounts of data (tens to hundreds of gigabytes per slide) that must be retrieved from secondary storage and processed. To effectively implement the data server, the system design relies on the computational power and high I/O throughput available from an appropriately configured parallel computer.

The Virtual Monte Carlo  

CERN Document Server

The concept of Virtual Monte Carlo (VMC) has been developed by the ALICE Software Project to allow different Monte Carlo simulation programs to run without changing the user code, such as the geometry definition, the detector response simulation or input and output formats. Recently, the VMC classes have been integrated into the ROOT framework, and the other relevant packages have been separated from the AliRoot framework and can be used individually by any other HEP project. The general concept of the VMC and its set of base classes provided in ROOT will be presented. Existing implementations for Geant3, Geant4 and FLUKA and simple examples of usage will be described.

The National Virtual Observatory  

CERN Document Server

As a scientific discipline, Astronomy is rather unique. We only have one laboratory, the Universe, and we cannot, of course, change the initial conditions and study the resulting effects. On top of this, acquiring Astronomical data has historically been a very labor-intensive effort. As a result, data has traditionally been preserved for posterity. With recent technological advances, however, the rate at which we acquire new data has grown exponentially, which has generated a Data Tsunami, whose wave train threatens to overwhelm the field. In this conference proceedings, we present and define the concept of virtual observatories, which we feel is the only logical answer to this dilemma.

Cerec omnicam and the virtual articulator--a case report.  

UK PubMed Central (United Kingdom)

This case report demonstrates how two opposing teeth were restored with full crowns using Cerec software version 4.2 (pre-release version). In addition, an anterior tooth was provided with a veneer. The situation was scanned with the Cerec Omnicam. The new virtual articulator was used for the design to obtain correct dynamic contacts. The Cerec Omnicam can scan the entire situation prior to preparation without the help of an assistant, as no surface pretreatment is necessary. The locations of the occlusal contacts can be marked with articulating paper and are indicated on the virtual models. Selective deletion of individual areas allows the prepared teeth to be rescanned, considerably speeding up the workflow. A video demonstration is available of the acquisition and design procedure.

Full Text Available Virtual organisation is a strategic paradigm that is centred on the use of information and ICT to create value. Virtual organisation is presented as a metamanagement strategy that has application in all value oriented organisations. Within the concept of Virtual organisation, the business model is an ICT based construct that bridges and integrates enterprise strategic and operational concerns. Firms try to ameliorate the impacts of risk and product complexity by forming alliances and partnerships with others to spread the risk of new products and new ventures and to increase organisational competence. The result is a networked virtual organization.

Body dissatisfaction and disordered eating attitudes in 7- to 11-year-old girls: testing a sociocultural model.  

UK PubMed Central (United Kingdom)

We examined the sociocultural model of body dissatisfaction and disordered eating attitude development in young girls for the first time. According to the model, internalizing an unrealistically thin ideal body increases the risk of disordered eating via body dissatisfaction, dietary restraint, and depression. Girls aged 7-11 years (N=127) completed measures of thin-ideal internalization, body dissatisfaction, dieting, depression, and disordered eating attitudes. Participants' height and weight were measured and their body mass index calculated. Thin-ideal internalization predicted disordered eating attitudes indirectly via body dissatisfaction, dietary restraint, and depression; it also predicted disordered eating attitudes directly. Path analyses showed that a revised sociocultural model fit well with the data. These data show that a sociocultural framework for understanding disordered eating and body dissatisfaction in adults is useful, with minor modifications, in understanding the development of related attitudes in young girls.

Allergic contact dermatitis.  

UK PubMed Central (United Kingdom)

Allergic contact dermatitis is a frequent inflammatory skin disease. The suspected diagnosis is based on clinical symptoms, a plausible contact to allergens and a suitable history of dermatitis. Differential diagnoses should be considered only after careful exclusion of any causal contact sensitization. Hence, careful diagnosis by patch testing is of great importance. Modifications of the standardized test procedure are the strip patch test and the repeated open application test. The interpretation of the SLS (sodium lauryl sulfate) patch test as well as testing with the patients' own products and working materials are potential sources of error. Accurate patch test reading is affected in particular by the experience and individual factors of the examiner. Therefore, a high degree of standardization and continuous quality control is necessary and may be supported by use of an online patch test reading course made available by the German Contact Dermatitis Research Group. A critical relevance assessment of allergic patch test reactions helps to avoid relapses and the consideration of differential diagnoses. Any allergic test reaction should be documented in an allergy ID card including the INCI name, if appropriate. The diagnostics of allergic contact dermatitis is endangered by a seriously reduced financing of patch testing by the German statutory health insurances. Restrictive regulations by the German Drug Law block the approval of new contact allergens for routine patch testing. Beside the consistent avoidance of allergen contact, temporary use of systemic and topical corticosteroids is the therapy of first choice.

Fortalezas familiares program: building sociocultural and family strengths in latina women with depression and their families.  

Science.gov (United States)

The purpose of this article is to describe Fortalezas Familiares (FF; Family Strengths), a community-based prevention program designed to address relational family processes and promote well-being among Latino families when a mother has depression. Although depression in Latina women is becoming increasingly recognized, risk and protective mechanisms associated with children's outcomes when a mother has depression are not well understood for Latino families. We begin by reviewing the literature on risk and protective psychosocial mechanisms by which maternal depression may affect Latino youth, using family systems theory and a developmental psychopathology framework with an emphasis on sociocultural factors shaping family processes. Next, we describe the theoretical basis and development of the FF program, a community-based 12-week intervention for Latina immigrant women with depression, other caregivers, and their children. Throughout this article, we use a case study to illustrate a Latina mother's vulnerability to depression and the family's response to the FF program. Recommendations for future research and practice include consideration of sociocultural processes in shaping both outcomes of Latino families and their response to interventions. PMID:24033237

Socio-cultural aspect of sexual practices and sexual offences - an Indian scenario.  

UK PubMed Central (United Kingdom)

Ignorance of the law of the land is no defence. Furthermore, it is a legal dictum that one should not be held criminally liable unless possessing a guilty mind. But during trials of some sexual offences in India it is often observed that the accused did not know that he had committed an offence because the crime in question was a part of his socio-cultural milieu. India is a vast country with great socio-cultural diversity and many different ethnic groups, each with its own distinct cultures. However, the entire Indian culture is religion based and finds its root from the ancient Holy Scriptures. The sexual culture of Indian society stems from the Kama Sutra of Vatsyayana, an epic on sex. This text is considered holy and is accepted culturally, even though many practices contained therein are offences under modern law. Child marriages and arranged marriages are an integral part of Indian society and in some tribes, even prostitution is socially sanctioned. However, all of these are also against the law. Many of the conflicts observed between the sexual practices that are accepted in Indian culture but not by the law can be explained on the basis that the Indian legal system is borrowed from that of the British.

SOCIO-CULTURAL CHARACTERISTICS OF RICE E-MARKETING USERS (CASE OF RASHT TOWNSHIP, IRAN)  

Directory of Open Access Journals (Sweden)

Full Text Available The main purpose of this research was to study the socio-cultural index of rice electronic marketing users in Rasht Township, Iran. This study used a survey design and was conducted with a random sample of 367 paddy farmers in Rasht Township. To identify the socio-cultural characteristics of rice e-marketing users, a self-designed questionnaire was developed to gather data. For determining the validity of the questionnaire, the face and content validity were used. Reliability for the instrument was estimated at 0.81. The Kurskal-Wallis and U Mann-Whitney test have been used to identify the effective factors on e-marketing. The result revealed that almost 68% of farmers had high tendency to adoption of electronic marketing and more than 70% of respondents chose rural ICT offices for rice e-marketing. Experience in using the internet services and internet skill had significant effects on e-marketing adoption. Finally, the result of this research presents a brokerage model. The nature of this model is (B2C) which means truck between business (ICT office) and customers. In this model, rural ICT offices have a role as buy/sell fulfillment.

Khat (Catha edulis): the herb with officio-legal, socio-cultural and economic uncertainty  

Scientific Electronic Library Online (English)

Full Text Available Abstract in english Khat (Catha edulis) is a plant of uncertain and highly controversial status grown in the countries around the Red Sea and on the eastern coast of Africa. The chewing of khat leaves has a deep-rooted religious and socio-cultural tradition. Khat is considered a cash crop and its cultivation is a source of economic value to the societies and nations involved. There have, however, been reports of negative economic effects on the individuals engaging in the habit of khat chewi (more) ng. The increasing use of khat worldwide, along with the negative international attention that this has garnered, has led to the present status of uncertainty of the once indigenous practice of khat chewing. Scientists, mostly western Europeans, have tended to focus on problems related to khat with little attention to the positive role of khat chewing in society and the world at large. In addition, no report has directly associated khat with any organised crime, violence or antisocial activity, particularly in countries where khat is legalised. This paper reviewed the various areas of uncertainty and controversy relating to khat. Based on the findings of the review, further qualitative and quantitative research is required and a positive international approach to khat use at economic, religious and socio-cultural levels is advocated.

Between life and death: exploring the sociocultural context of antenatal mental distress in rural Ethiopia.  

UK PubMed Central (United Kingdom)

The high prevalence of antenatal common mental disorders in sub-Saharan Africa compared to high-income countries is poorly understood. This qualitative study explored the sociocultural context of antenatal mental distress in a rural Ethiopian community. Five focus group discussions and 25 in-depth interviews were conducted with purposively sampled community stakeholders. Inductive analysis was used to develop final themes. Worry about forthcoming delivery and fears for the woman's survival were prominent concerns of all participants, but only rarely perceived to be pathological in intensity. Sociocultural practices such as continuing physical labour, dietary restriction, prayer and rituals to protect against supernatural attack were geared towards safe delivery and managing vulnerability. Despite strong cultural norms to celebrate pregnancy, participants emphasised that many pregnancies were unwanted and an additional burden on top of pre-existing economic and marital difficulties. Short birth interval and pregnancy out of wedlock were both seen as shameful and potent sources of mental distress. The notion that pregnancy in traditional societies is uniformly a time of joy and happiness is misplaced. Although antenatal mental distress may be self-limiting for many women, in those with enduring life difficulties, including poverty and abusive relationships, poor maternal mental health may persist.

Socio-cultural aspects of oral health among the Fulani in Ferlo (Senegal): a qualitative study.  

UK PubMed Central (United Kingdom)

OBJECTIVES: Health is a subjective concept that considers the social, cultural, environmental and behavioural problems of the individual. This study was conducted with the objective of better understanding the sociocultural aspects related to the oral health of the Fulani populations of Ferlo, Senegal. METHODS: The study was qualitative and based in the area of the Great Green Wall (GGW) in the region known as Ferlo, northern Senegal. Data were collected by semi-structured interviews in a sample of the population and through discussions with a focus group. It concerned health and aesthetics of the teeth, care and traditional herbal recipes, teeth and superstitions. RESULTS: It appears that people were using the toothpick, the chewing stick and/or charcoal to clean their teeth. Confusion persisted with respect to the types of food consumed that were implicated in the occurrence of dental caries: tea, rice, 'jumbo' (a seasoning spice) and tobacco. 'Borom bop', which means 'master of the head', was the most commonly reported cause of caries. Healthy, beautiful teeth were attributes of beauty and elegance, enhanced by tattoos and crafted crowns in the Fulani. Their health problems were generally managed by healers or traditional practitioners who based their practices on empirical and 'handed down' knowledge. Socio-anthropological meanings were given to children with neonatal teeth. CONCLUSIONS: It is therefore important to consider the sociocultural aspects in oral health projects and programmes; the place of herbal medicine in dentistry should be recognized and maybe researched in the region of the Great Green Wall.

Curcumin is used as a spice in foods, as a treatment in traditional medicine, as a dye for fur, and as a component in nutritional supplements. A few cases of allergic contact dermatitis from curcumin have been reported. We report two cases of contact urticaria from curcumin. These cases are mediated by two different mechanisms of contact urticaria: nonimmunologic and immunologic (immunoglobulin-E mediated).

Real time Virtual View Generation For Augmented Virtuality System  

Directory of Open Access Journals (Sweden)

Full Text Available This paper describes a novel method of real-time virtual view generation for augmented virtuality system. The aim is to rectify the displacement between virtual eye position and video cameras which are attached on the head mounted display. It consists of three steps: Firstly, stereo calibration was used to generate cameras' internal and external parameters, and then image planes were rectified to canonical configuration state that made them alignment or corresponding points on the same scan lines. At last the virtual view images between two cameras are generated using view morphing which is a shape-preserving transition method from a source to a destination view. We can adopt this method to choose locations of two virtual cameras yielding an in-between stereoscopic camera views without reconstructing the 3D model of the object. The view of the object corresponding to a virtual camera that is located between two real cameras with same position of eyes. So we can control the feeling of depth and provide customized viewpoint to the user. It can be used in a variety of augmented virtuality applications to integrate live video objects into virtual environments. Experimental results verify the validity of the proposed approach, and we also show interlaced stereo composition results using a pair of synthesized views from input views acquired by stereo cameras.

Virtually assisted optical colonoscopy  

Science.gov (United States)

We present a set of tools used to enhance the optical colonoscopy procedure in a novel manner with the aim of improving both the accuracy and efficiency of this procedure. In order to better present the colon information to the gastroenterologist performing a conventional (optical) colonoscopy, we undistort the radial distortion of the fisheye view of the colonoscope. The radial distortion is modeled with a function that converts the fisheye view to the perspective view, where the shape and size of polyps can be more readily observed. The conversion, accelerated on the graphics processing unit and running in real-time, calculates the corresponding position in the fisheye view of each pixel on the perspective image. We also merge our previous work in computer-aided polyp detection for virtual colonoscopy into the optical colonoscopy environment. The physical colonoscope path in the optical colonoscopy is approximated with the hugging corner shortest path, which is correlated with the centerline in the virtual colonoscopy. With the estimated distance that the colonoscope has been inserted, we are able to provide the gastroenterologist with visual cues along the observation path as to the location of possible polyps found by the detection process. In order to present the information to the gastroenterologist in a non-intrusive manner, we have developed a friendly user interface to enhance the optical colonoscopy without being cumbersome, distracting, or resulting in a more lackadaisical inspection by the gastroenterologist.

Deeply Virtual Neutrino Scattering  

International Nuclear Information System (INIS)

We investigate the extension of the deeply virtual Compton scattering process into the weak interaction sector. Standard electromagnetic Compton scattering provides a unique tool for studying hadrons, which is one of the most fascinating frontiers of modern science. In this process the relevant Compton scattering amplitude probes the hadron structure by means of two quark electromagnetic currents. We argue that replacing one of the currents with the weak interaction current can promise a new insight. The paper is organized as follows. In Sec. II we briefly discuss the features of the handbag factorization scheme. We introduce a new set of phenomenological functions, known as generalized parton distributions (GPDs) [1-6], and discuss some of their basic properties in Sec. III. An application of the GPD formalism to the neutrino-induced deeply virtual Compton scattering in the kinematics relevant to future high-intensity neutrino experiments is given in Sec. IV. The cross section results are presented in Sec. V. Finally, in Sec. VI we draw some conclusions and discuss future prospects. Some of the formal results in this paper have appeared in preliminary reports in Refs. [7] and [8], whereas a comprehensive analysis of the weak neutral and weak charged current DVCS reactions in collaboration with W. Melnitchouk and A. Radyushkin has been presented in Ref. [9].

Contact alternatives to nickel.  

UK PubMed Central (United Kingdom)

Allergic contact dermatitis to nickel is a continued health concern internationally. Nickel has been found to be the most prevalent and relevant allergen in tested populations for the last 3 decades. Furthermore, recent data from the North American Contact Dermatitis Group demonstrate positive patch-test reactions to nickel at approximately 19.5% of their tested population and a significant increase in the positivity rates for the last decade (Dermatitis. 2013;24:10-21. J Am Acad Dermatol. 1998;38:911-918). Because of the rise in allergic contact dermatitis rates to nickel, the American Contact Dermatitis Society recognized nickel to be the 2008 Allergen of the Year (J Am Acad Dermatol. 2009;60:1067-1069; Dermatitis. 2008;19:3-8). This article recognizes the importance of nickel avoidance and highlights potential alternatives.

Contact Detection Algorithms  

Directory of Open Access Journals (Sweden)

Full Text Available A process that determines whether two or more bodies make contact at one or more points is called contact detection or collision detection. Contact detection is inseparable part of the computer graphics, surgical simulations, and robotics etc. There are large of methods that are used for collision detection. We will review a few of the most common ones. Algorithms for contact determination can be grouped into two general categories - broad-phase and narrow-phase-. This paper provides a comprehensive classification of a collision detection literature for the two phases. Moreover, we have attempted to explain some of the existing algorithms which are not easy to interpret. In the process, we have tried to keep sections self-explanatory without sacrificing depth of the coverage.

Occupational Contact Dermatitis  

Directory of Open Access Journals (Sweden)

Full Text Available Occupational contact dermatitis accounts for 90% of all cases of work-related cutaneous disorders. It can be divided into irritant contact dermatitis, which occurs in 80% of cases, and allergic contact dermatitis. In most cases, both types will present as eczematous lesions on exposed parts of the body, notably the hands. Accurate diagnosis relies on meticulous history taking, thorough physical examination, careful reading of Material Safety Data Sheets to distinguish between irritants and allergens, and comprehensive patch testing to confirm or rule out allergic sensitization. This article reviews the pathogenesis and clinical manifestations of occupational contact dermatitis and provides diagnostic guidelines and a rational approach to management of these often frustrating cases.

Acoustoconductance of quantum contacts  

CERN Multimedia

We describe theoretically the acoustoconductance (AC) of quantum contacts. One characteristic of a contact which distinguishes it from a long, uniform wire is a strong, energy-dependent transmission probability. This has several consequences for AC. Electrons which are forward scattered by phonons can contribute to AC and, furthermore, AC can have positive sign (i.e. a conductance-increase under the influence of phonons). By contrast, for uniform wires only backscattered electrons contribute to AC which always has negative sign.

International Nuclear Information System (INIS)

The manifestations of the ? ? 3? contact term and its unitary partners are investigated in the framework of the chiral effective Lagrangian theory with vector mesons. We conclude that, nowadays, the existence and magnitude of the contact term can be extracted neither from theory nor from experiment. The theoretical uncertainty is caused by the one-loop corrections. Some speculations about them lead to the generalized KSRF relation. 53 refs., 5 figs., 1 tab.

Tomato contact dermatitis  

DEFF Research Database (Denmark)

The tomato plant (Solanum lycopersicum) is an important crop worldwide. Whereas immediate-type reactions to tomato fruits are well known, contact dermatitis caused by tomatoes or tomato plants is rarely reported. The aims of this study were to present new data on contact sensitization to tomato plants and review the literature on contact dermatitis caused by both plants and fruits. An ether extract of tomato plants made as the original oleoresin plant extracts, was used in aimed patch testing, and between 2005 and 2011. 8 of 93 patients (9%) tested positive to the oleoresin extracts. This prevalence is in accordance with the older literature that reports tomato plants as occasional sensitizers. The same applies to tomato fruits, which, in addition, may cause protein contact dermatitis. The allergens of the plant are unknown, but both heat-stable and heat-labile constituents seem to be involved. The fruit contains fragrance compounds that are also present in Myroxylon pereirae (balsam of Peru), possibly accounting for cross-reactivity. The proteins in pulp and peel may contribute to protein contact dermatitis. Until more is known about the allergens, the diagnosis of contact dermatitis caused by tomato plants and fruit may be established with the use of ether extracts and fresh fruits, respectively.

Adhesive contact in filaments  

International Nuclear Information System (INIS)

This paper studies the elastic contact in filaments induced by surface adhesion, which plays an important role in the mechanical response of fibrous materials (e.g. fibre friction, sliding, compression hysteresis, etc). During the process, a simple 3D elastic contact model was proposed. The filaments were assumed to be uniform, smooth elastic cylinders and the adhesive force between filaments in contact was estimated according to Bradley's approach (Bradley 1932 Phil. Mag. 13 853) that relies on the filament configurations before deformation. Under the action of fibre surface adhesion, the elastic deformation and the size of the contact zone were determined in closed-form based on the DMT theory (Derjaguin et al 1975 J. Colloid Interface Sci. 53 314). Effects of filament radius and orientation, surface energies and elasticity on the elastic deformation and the size of the contact zone were explored numerically. The model developed in this work can be used for the study of the mechanisms of filament contacts, friction, sliding and compression hysteresis in fibrous materials subjected to external loading.

Virtual autopsy in hanging.  

Science.gov (United States)

The aim of the study was to compare postmortem computed tomographic (CT) imaging findings from a case of hanging with the autopsy findings. The CT showed a good match with autopsy findings especially for bone, soft tissue, and spinal injuries. The CT images of the injuries of the neck obtained by CT scan clearly showed the ligature mark, the hemorrhagic suffusion in the soft tissue (thickening of derma) and in the muscles (sternocleidomastoid) of the neck. Furthermore, CT 3-dimensional reconstruction showed brain edema, fracture of the left posterior horn of the hyoid bone, and a grade 1 retrolisthesis of C5 on C6. This last finding was not detected by autopsy because of the anterior approach that is frequently used in necropsy technique. Nevertheless, the CT virtual autopsy did not show vascular findings (like Amussat mark) because a barium mixture was not injected in the body. PMID:23629397

VIRTUAL REALITY HYPNOSIS  

Science.gov (United States)

Scientific evidence for the viability of hypnosis as a treatment for pain has flourished over the past two decades (Rainville, Duncan, Price, Carrier and Bushnell, 1997; Montgomery, DuHamel and Redd, 2000; Lang and Rosen, 2002; Patterson and Jensen, 2003). However its widespread use has been limited by factors such as the advanced expertise, time and effort required by clinicians to provide hypnosis, and the cognitive effort required by patients to engage in hypnosis. The theory in developing virtual reality hypnosis was to apply three-dimensional, immersive, virtual reality technology to guide the patient through the same steps used when hypnosis is induced through an interpersonal process. Virtual reality replaces many of the stimuli that the patients have to struggle to imagine via verbal cueing from the therapist. The purpose of this paper is to explore how virtual reality may be useful in delivering hypnosis, and to summarize the scientific literature to date. We will also explore various theoretical and methodological issues that can guide future research. In spite of the encouraging scientific and clinical findings, hypnosis for analgesia is not universally used in medical centres. One reason for the slow acceptance is the extensive provider training required in order for hypnosis to be an effective pain management modality. Training in hypnosis is not commonly offered in medical schools or even psychology graduate curricula. Another reason is that hypnosis requires far more time and effort to administer than an analgesic pill or injection. Hypnosis requires training, skill and patience to deliver in medical centres that are often fast-paced and highly demanding of clinician time. Finally, the attention and cognitive effort required for hypnosis may be more than patients in an acute care setting, who may be under the influence of opiates and benzodiazepines, are able to impart. It is a challenge to make hypnosis a standard part of care in this environment. Over the past 25 years, researchers have been investigating ways to make hypnosis more standardized and accessible. There have been a handful of studies that have looked at the efficacy of using audiotapes to provide the hypnotic intervention (Johnson and Wiese, 1979; Hart, 1980; Block, Ghoneim, Sum Ping and Ali, 1991; Enqvist, Bjorklund, Engman and Jakobsson, 1997; Eberhart, Doring, Holzrichter, Roscher and Seeling, 1998; Perugini, Kirsch, Allen, et al., 1998; Forbes, MacAuley, Chiotakakou-Faliakou, 2000; Ghoneim, Block, Sarasin, Davis and Marchman, 2000). These studies have yielded mixed results. Generally, we can conclude that audio-taped hypnosis is more effective than no treatment at all, but less effective than the presence of a live hypnotherapist. Grant and Nash (1995) were the first to use computer-assisted hypnosis as a behavioural measure to assess hypnotizability. They used a digitized voice that guided subjects through a procedure and tailored software according to the subject’s unique responses and reactions. However, it utilized conventional two-dimensional screen technology that required patients to focus their attention on a computer screen, making them vulnerable to any type of distraction that might enter the environment. Further, the two-dimensional technology did not present compelling visual stimuli for capturing the user’s attention.

Realistic Visualization of Virtual Views and Virtual Cinema  

DEFF Research Database (Denmark)

Realistic Virtual View Visualization is a new field of research which has received increasing attention in recent years. It is strictly related to the increased popularity of virtual reality and the spread of its applications, among which virtual photography and cinematography. The use of computer generated characters, "virtual actors", in the motion picture production increases every day. While the most known computer graphics techniques have largely been adopted successfully in nowadays fictions, it still remains very challenging to implement virtual actors which would resemble, visually, human beings. Interestingly, film directors have been looking at the recent progress achieved by the research community in the field of realistic visualization of virtual views, and they have successfully implemented state of the art research approaches in their productions. An innovative concept is then gaining consensus: the augmented actor. Fundamental concepts and examples of methods proposed for realistic view synthesis, based on the transfer of photorealism from reference photographs to novel views, will be presented. The application of methods for realistic image synthesis to virtual cinematography will also be illustrated with examples from the recent movie sequel: "The Matrix" and "The Matrix Reloaded".

Virtual reality and anthropology  

Energy Technology Data Exchange (ETDEWEB)

Since the discovery of the Tyrolean Iceman in 1991 advanced imaging and post processing techniques were successfully applied in anthropology. Specific techniques include spiral computed tomography and 3-dimensional reconstructions including stereolithographic and fused deposition modeling of volume data sets. The Iceman's skull was the first to be reproduced using stereolithography, before this method was successfully applied in preoperative planning. With the advent of high-end graphics workstations and biomedical image processing software packages, 3-dimensional reconstructions were established as a routine tool for analyzing volume data sets. These techniques opened totally new insights in the field of physical anthropology. Computed tomography became the ideal research tool to access the internal structures of various precious fossils without damaging or even touching them. Many of the most precious specimens from the species Autralopithecus (1.8-3.5 Myears), Homo heidelbergensis (200-600 kyears) or Homo neanderthalensis (40-100 kyears) were scanned during the last 5 years. Often the fossils are filled with a stone matrix or other materials. During the postprocessing routines highly advanced algorithms were used to remove virtually these incrustations. Thus it was possible to visualize the morphological structures that lie beneath the matrix. Some specimens were partially destroyed, so the missing parts were reconstructed on computer screen in order to get estimations of the brain volume and endocranial morphology, both major fields of interest in physical anthropology. Moreover the computerized form of the data allows new descriptions of morphologic structures by the means of 'geometric morphometrics'. Some of the results may change aspects and interpretations in human evolution. The introduction of new imaging and post processing techniques created a new field of research: Virtual Anthropology.

Specific techniques include spiral computed tomography and 3-dimensional reconstructions including stereolithographic and fused deposition modeling of volume data sets. The Iceman's skull was the first to be reproduced using stereolithography, before this method was successfully applied in preoperative planning. With the advent of high-end graphics workstations and biomedical image processing software packages, 3-dimensional reconstructions were established as a routine tool for analyzing volume data sets. These techniques opened totally new insights in the field of physical anthropology. Computed tomography became the ideal research tool to access the internal structures of various precious fossils without damaging or even touching them. Many of the most precious specimens from the species Autralopithecus (1.8-3.5 Myears), Homo heidelbergensis (200-600 kyears) or Homo neanderthalensis (40-100 kyears) were scanned during the last 5 years. Often the fossils are filled with a stone matrix or other materials. During the postprocessing routines highly advanced algorithms were used to remove virtually these incrustations. Thus it was possible to visualize the morphological structures that lie beneath the matrix. Some specimens were partially destroyed, so the missing parts were reconstructed on computer screen in order to get estimations of the brain volume and endocranial morphology, both major fields of interest in physical anthropology. Moreover the computerized form of the data allows new descriptions of morphologic structures by the means of 'geometric morphometrics'. Some of the results may change aspects and interpretations in human evolution. The introduction of new imaging and post processing techniques created a new field of research: Virtual Anthropology.

The virtual knife  

DEFF Research Database (Denmark)

Since post World War II and until 2008 the Danish pig producing industry (DPPI) has been in a continuing state of growth. In spite of an ever fiercer competition DPPI has managed to protect its position as export leader by maintaining a focus on research and development. Today, DPPI is in a state of recession and must increase the efficiency if not to reduce the production capacity further. The industry recognizes that a more efficient use of the raw materials is one of the largest and most important challenges. To meet this challenge it is a necessity to get a better understanding of the biological variation of pigs. The development of models for describing the biological variation of pigs is one of the key components needed to attain a better sorting of the pig carcasses and an improved cutting in the abattoirs. Such models can be related to possible products, which can be related to potential yield and order books. The Danish Meat Research Institute (DMRI) is currently constructing a representative database of virtual representations of pigs using X-ray Computed Tomography (CT). The database will serve as the foundation for the diversity modeling of pigs and for extracting predictors of quality and optimal use. This thesis integrates well-known techniques from the medical image analysis into the development of tools for automated analysis of the morphology of pigs. E.g. elastic image matching has been applied to establish spatial correspondence between the virtual representations of pigs in the database. The establishment of spatial correspondence is an essential preprocessing step for most automated analysis using the database.

Using virtual reality to assess user experience.  

UK PubMed Central (United Kingdom)

OBJECTIVE: The aim of this article is to discuss how user experience (UX) evaluation can benefit from the use of virtual reality (VR). BACKGROUND: UX is usually evaluated in laboratory settings. However, considering that UX occurs as a consequence of the interaction between the product, the user, and the context of use, the assessment of UX can benefit from a more ecological test setting. VR provides the means to develop realistic-looking virtual environments with the advantage of allowing greater control of the experimental conditions while granting good ecological validity. METHOD: The methods used to evaluate UX, as well as their main limitations, are identified.The currentVR equipment and its potential applications (as well as its limitations and drawbacks) to overcome some of the limitations in the assessment of UX are highlighted. RESULTS: The relevance of VR for UX studies is discussed, and a VR-based framework for evaluating UX is presented. CONCLUSION: UX research may benefit from a VR-based methodology in the scopes of user research (e.g., assessment of users' expectations derived from their lifestyles) and human-product interaction (e.g., assessment of users' emotions since the first moment of contact with the product and then during the interaction). APPLICATION: This article provides knowledge to researchers and professionals engaged in the design of technological interfaces about the usefulness of VR in the evaluation of UX.

[New kinds of relationships on the internet. Virtual object relations in psychotherapy  

UK PubMed Central (United Kingdom)

Communication in the internet by e-mail is gaining in significance in counseling and psychotherapy of suicidal patients as well as an additional communication in face-to-face psychotherapy. E-Mail contacts during psychodynamic psychotherapy are defined as a transference offer of a virtual object relation. In two case descriptions of suicidal patients, examples of making contact with psychotherapy on the internet are presented. The concept of the virtual object is explained and its application for understanding these initial scenes and phenomena is discussed.

Quasi-stationary simulation: the subcritical contact process  

Scientific Electronic Library Online (English)

Full Text Available Abstract in english We apply the recently devised quasi-stationary simulation method to study the lifetime and order parameter of the contact process in the subcritical phase. This phase is not accessible to other methods because virtually all realizations of the process fall into the absorbing state before the quasi-stationary regime is attained. With relatively modest simulations, the method yields an estimate of the critical exponent nu|| with a precision of 0.5%.

Intergroup contact theory.  

Science.gov (United States)

Allport specified four conditions for optimal intergroup contact: equal group status within the situation, common goals, intergroup cooperation and authority support. Varied research supports the hypothesis, but four problems remain. 1. A selection bias limits cross-sectional studies, since prejudiced people avoid intergroup contact. Yet research finds that the positive effects of cross-group friendship are larger than those of the bias. 2. Writers overburden the hypothesis with facilitating, but not essential, conditions. 3. The hypothesis fails to address process. The chapter proposes four processes: learning about the outgroup, changed behavior, affective ties, and ingroup reappraisal. 4. The hypothesis does not specify how the effects generalize to other situations, the outgroup or uninvolved outgroups. Acting sequentially, three strategies enhance generalization-decategorization, salient categorization, and recategorization. Finally, both individual differences and societal norms shape intergroup contact effects. The chapter outlines a longitudinal intergroup contact theory. It distinguishes between essential and facilitating factors, and emphasizes different outcomes for different stages of contact. PMID:15012467

Solar cell contacts  

Energy Technology Data Exchange (ETDEWEB)

Two experimental contact systems were examined and compared to a baseline contact system consisting of evaporated layers of titanium, palladium, and silver and an electroplated layer of copper. The first experimental contact system consisted of evaporated layers of titanium, nickel, and copper and an electroplated layer of copper. This system performed as well as the baseline system in all respects, including its response to temperature stress tests, to a humidity test, and to an accelerated aging test. In addition, the cost of this system is estimated to be only 43% of the cost of the baseline system at a production level of 25 MW/year. The second experimental contact system consisted of evaporated layers of nickel and copper and an electroplated layer of copper. Cells with this system show serious degradation in a temperature stress test at 350/sup 0/C for 30 minutes. Auger Electron Spectroscopy was used to show that the evaporated nickel layer is not an adequate barrier to copper diffusion even at temperatures as low as 250/sup 0/C. This fact brings into question the longterm reliability of this contact system.

Declining Physical Activity and the Socio-Cultural Context of the Geography of Industrial Restructuring: A Novel Conceptual Framework.  

UK PubMed Central (United Kingdom)

BACKGROUND: At the population level, the prevalence of physical activity has declined considerably in many developed countries in recent decades. There is some evidence that areas exhibiting the lowest activity levels are those which have undergone a particularly strong transition away from employment in physically demanding occupations. We propose that processes of deindustrialisation may be causally linked to unexplained geographical disparities in levels of physical activity. Whilst the socio-cultural correlates of physical activity have been well studied, and prior conceptual frameworks have been developed to explain more general patterns of activity, none have explicitly attempted to identify the components of industrial change that may impact physical activity. METHODS: In this work we review the current literature on socio-cultural correlates of health behaviours before using a case study centred on the United Kingdom to present a novel framework that links industrial change to declining levels of physical activity. RESULTS: We developed a comprehensive model linking socio-cultural correlates of physical activity to processes associated with industrial restructuring and discuss implication for policy and practice. CONCLUSIONS: A better understanding of socio-cultural processes may help to ameliorate adverse health consequences of employment decline in communities that have experienced substantial losses of manual employment.

Discourse activity in the science classroom: a socio-cultural analytical and planning tool for teaching  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper an analytical tool, or framework, for charactersing the ways in which teachers interact with students to promote meaning making, on the social plane of high school science classes, is introduced. The development of the framework is based on sociocultural theory and each of the five aspects of the framework is outlined before being applied to the analysis of a short science teaching and learning sequence. Some fundamental points for science teaching arise out of this analysis, particularly in relation to what is identified as being the central aspect of ‘communicative approach’. Finally the potential of the framework as both an analytical and a planning tool is discussed in the context of teacher professional developmen

[Sociocultural etiology to guide community control of malaria in Cote d'Ivoire].  

UK PubMed Central (United Kingdom)

In the rural communities of Côte d'Ivoire, malaria control is guided by the sociocultural etiology or perception of this disease, as we can see by studies conducted in the Baoulé and Gouro communities. These studies show that these communities establish a link between the sun, excessive oil consumption, agricultural activities, disease, and lack of hygiene. Mosquitoes, however, are not identified as the cause of malaria but rather as an insect noxious by their noise and painful bites. These populations use both traditional and modern means to move mosquitoes away from their homes. Analysis of this social reality shows that the battle against malaria in rural areas is not simply a problem of health education. It is thus important in developing malaria control programmes to adopt a strategy that links community participation and health education.

Sociocultural factors in the development of bulimia nervosa in a blind woman: a case report.  

UK PubMed Central (United Kingdom)

BACKGROUND: Although several cases of eating disorders in visually impaired women have been reported, there has been little research on the development of body image and disordered eating in the blind. Overall, it is argued that blind women are protected from developing body dissatisfaction because of having had little or no exposure to thin-ideal images, and that if they do develop an eating disorder, this would be linked to other risk factors. In the one reported case of bulimia nervosa in a blind woman, body image concerns were even absent. METHOD: We report a single case of bulimia nervosa in a 28-year-old congenitally blind woman whose presentation was typical, including body dissatisfaction and drive for thinness. DISCUSSION: The present case underscores the need to also consider an etiological role of perceived sociocultural pressure and thin-ideal internalization in promoting body dissatisfaction and eating disorders in visually impaired women.

Sociocultural interactions with wild fauna in a conservation unit at the Amazon: gender and generational relations  

Directory of Open Access Journals (Sweden)

Full Text Available This article describes socioculturally established interactions between inhabitants of Unini River, at Jau National Park, Central Amazon, with the local wild fauna. The diversity of these interactions and how their reproduction is influenced by associated factors of gender and generation. The methodological procedures used were participative observation and focus group workshops. In these workshops, free-listings of wild fauna related to diverse forest habitats and ecological niches were produced and the degree of similarity and dissimilarity between those lists were analyzed using the Jaccard index, illustrated in dendrograms. In general, mental associations between fauna and habitats are similar among community members. Nevertheless, effects of gender and generation are noticeable. Reproduction of such interaction permeates the issue of habitus, which structures the socialization process of cultural interaction with the local fauna.

Sociocultural Approach to Assessment of Child Development and Learning in Preschool Education  

Directory of Open Access Journals (Sweden)

Full Text Available Assessment is integral to preschool curriculum. Within contemporary preschool pedagogy, the assessment of child development and learning, which represents a basis for curriculum planning, is considered one of preschool standards of quality. In this paper, we present the difference between scientific observation which is based on developmental psychology, and the pedagogical assessment of child development and learning. We outline the purpose of assessing child development and learning in early childhood and introduce two different approaches to assessment, namely, the decontextualised approach which focuses on monitoring a child out of the context and the sociocultural approach which aims to identify and understand a child and his or her learning in the physical and the social context.

Children's Learning in the Diverse Socio-Cultural Context of South Africa.  

UK PubMed Central (United Kingdom)

Children develop in several interlocking systems-in the context of their family, and within the interaction of settings such as home, school, and church (Russell, 2011). In South Africa, children's diverse backgrounds within families, neighborhoods and socio-cultural environments provide them with varied experiences and opportunities to learn. Whether growing up in urban or rural communities, belonging to a specific race and ethnic group, or being poor or rich, all imply exposure to cultures, lifestyles, amenities, and living conditions that differ in marked ways (Makoe, 2006). With 79% of the total population being Blacks, the racial and ethnic heterogeneity translates into a complex mix of languages: English, Afrikaans, nine indigenous languages and five Indian languages are spoken (Reagan, 2001).

Under-reporting of gossypiboma in a third-world country. A sociocultural view  

Directory of Open Access Journals (Sweden)

Full Text Available The paper looks at the reason for the low reportage of retained abdominal packs following an abdominal operation in a third world country like Nigeria. It is generally agreed that this unfortunate situation is under-reported. The reason for under-reporting is now given a socio-cultural perspective. Fear of litigation does not seem to be paramount here like it would be in the western (developed) world. Other explanations like fear of being made a scapegoat for something which may be due to spiritual attacks may be more important. The paper concludes by recommending that the removal of impediments to disclosure of this adverse surgical event will lie in education, discouragement of scapegoatism and improvement in hospital services in the third world.

Social physique anxiety and sociocultural attitudes toward appearance impact on orthorexia test in fitness participants.  

Science.gov (United States)

This study investigates how scores on the Social Physique Anxiety Scale (SPAS) and the Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ) relate to Bratman's orthorexia test (BOT) scores with regard to age, sex, and self-reported exercise frequency and duration in a sample of Swedish participants in fitness center activities. A total of 251 participants (166 women and 85 men) completed the SPAS, the SATAQ, and a questionnaire focusing on exercise frequency and duration. The results indicated that the SATAQ subdomain internalization could itself explain the variation in BOT results. In women, the results indicated that exercise frequency, followed by SPAS score and the SATAQ subdomains internalization and awareness, could together explain the variation in BOT results. Fitness centers could make a point of emphasizing that some physical ideals are neither healthy nor realistic, thus strengthening member self-image and preventing social physique anxiety, eating disorders, and negative attitudes toward appearance.

[Social psychological and sociocultural aspects of alcohol drinking and alcoholic intoxication behind the wheel  

UK PubMed Central (United Kingdom)

The paper deals with socio-psychological and socio-cultural problems of drunken driving and of alcohol-consumption in general. It is the intention to make evident how the way to show a certain behavior is imbedded in more comprehensive conditions. The contradictory relations between the role of individual traffic and of alcohol consumption in a society on the one hand and the phenomenon of drunken driving on the other hand are pointed out, as well as the different valuation of social drinking and alcohol dependence. The way of profanation of the drug "alcohol" and the importance of social influence on consumption and effect of the drug are shown, taking into consideration the subjective position of the individual in the society. Finally the role of the state and possibilities of a systemic approach against drunken driving are dealt with.

Perceptions of Psychopathology in Relation to Socio-cultural Changes Among Ladakhi Youth  

DEFF Research Database (Denmark)

It seems likely that an increasing number of young people in the isolated region of Ladakh are experiencing mental problems in relation to the process of acculturation. Ladakh, a Himalayan region situated in the northeast of India, has undergone rapid development. It has been influenced by the opening of the area for tourists in 1974 and from the massive presence of the Indian military. This work explores the discourses among intellectuals, practitioners and young people about psychopathology among the Ladakhi youth in relation to socio-cultural changes. Based on the discourse analysis and a review of relevant theoretical perspectives, it is argued that development is causing a greater diversity in the youth, and that the combination of greater pressure and less cultural support may be causing an increase in psychopathology.

Sharing the Joke? ‘Britcom’ Remakes in the United States: A Historical and Socio-Cultural Perspective  

Directory of Open Access Journals (Sweden)

Full Text Available In an increasingly ‘glocalized’ world, the success of NBC’s still-running remake of the BBC’s The Office would seem to indicate the continuing vitality of ‘Britcom’ adaptations on American network television. Initiated by US producer and comedy writer Norman Lear in the early 1970s, such cross-cultural translation has nevertheless had a long history of hit-or-miss experiences over the decades. Following an analysis of how the early television developments of the situation comedy genre in both countries may have favoured the emergence of different types of sitcom humour, this article will introduce several case-studies of US ‘Britcom’ remakes so as to map out the socio-cultural specificities at work in the retooling process central to such exchanges from the British to the American television industry.

Microkernels Meet Recursive Virtual Machines  

UK PubMed Central (United Kingdom)

This paper describes a novel approach to providingmodularand extensible operating system functionality and encapsulatedenvironments based on a synthesis of microkerneland virtual machine concepts. We have developeda software-based virtualizable architecture called Flukethat allows recursive virtual machines (virtual machinesrunning on other virtual machines) to be implemented efficientlyby a microkernel running on generic hardware.A complete virtual machine interface is provided at eachlevel; efficiency derives from needing to implement onlynew functionality at each level. This infrastructure allowscommon OS functionality, such as process management,demand paging, fault tolerance, and debugging support, tobe provided by cleanly modularized, independent, stackablevirtual machine monitors, implemented as user processes.It can also provide uncommon or unique OS features,including the above features specialized for particularapplications' needs, virtual machines transparently distributedcross-node, or security monitors that allow arbitraryuntrusted binaries to be executed safely. Our prototypeimplementation of this model indicates that it is practicalto modularize operating systems this way. Some typesof virtual machine layers impose almost no overhead at all,while others impose some overhead (typically 0--35%), butonly on certain classes of applications.1

[Computers and contact dermatitis  

UK PubMed Central (United Kingdom)

A computerized database with the complete composition of pharmaceutical products and some cosmetics helps the patient with an allergic contact dermatitis reaction to avoid his specific allergens. Together with a database with patient information (12000 cases) this product, file serves as the basis for an expert system that assists the dermatologist during his every day clinical practice. The use of the computer in the field of contact dermatitis has gained much interest in the course of the last decade. In fact, the computer can be a particularly helpful tool in: 1. The storage of large amounts of data that can help to identify the patient's allergen microenvironment: --literature: articles related to contact dermatitis problems; --product information such as, for example, the composition of pharmaceutical, cosmetics, and industrial materials; --the dermatologist: the filling in of a standardized anamnesis from also helps to assure that relevant clinical data is not overlooked. 2. The diagnosis of allergic contact dermatitis: on the basis of all these data stored, an expert system can be developed to provide targeted information to assist the physician with the anamnesis of a new patient. Depending on the profile of the patient, several factors that could be at the source of the contact dermatitis, such as the patient's profession, hobbies, and use of pharmaceutical products and cosmetics, can be considered, thus increasing the efficiency of the allergological examination considerably. 3. Research in contact dermatitis: --The data can be used for epidemiological analyses in behalf of the patients, the medical profession, the industry, and the authorities.(ABSTRACT TRUNCATED AT 250 WORDS)

Sociocultural determinants associated to pneumonia in Puno, Peru: a qualitative study  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To identify the sociocultural determinants of pneumonia through the perception of health workers and community in Puno, Peru. Methods: From June 8 to 11, 2009, we applied qualitative techniques including focus groups in administrative workers of the Regional Health Directorate of Puno, healthcare workers from a public hospital of the province of Juliaca, Puno, and schoolchildren between 8 and 9 years from a public school in the province of Juliaca. Projective techniques were also applied to the schoolchildren, who through free drawing expressed their feelings, opinions, reasons for behaviors and attitudes of both children and their parents, related to pneumonia. Focus groups were recorded and later transcribed; we also interviewed two relatives of a girl who died from pneumonia in the community of Uros, Puno, using a questionaire guide.Results: The determinants associated with pneumonia that were identified are lack of leadership and coordination of health workers in the care of patients with pneumonia, delayed in care and payments for health services, the influence of the mother-in-law who decides what to do with children with pneumonia, parents who medicate their children, children that stay alone at home uintil late at night and a delay in the attendance to the hospital; health workers recognized that attention in health services is limited and not of quality. Conclusions: The sociocultural determinants are lack of leadership and coordination of health teams, delays in care and payments for services, the mother-in law influence in decision making, self-medication and going to the hospital when the child is seriously ill.

Socio-cultural aspects of oral health among the Fulani in Ferlo (Senegal): A qualitative study.  

Science.gov (United States)

Abstract Objectives. Health is a subjective concept that considers the social, cultural, environmental and behavioural problems of the individual. This study was conducted with the objective of better understanding the sociocultural aspects related to the oral health of the Fulani populations of Ferlo, Senegal. Methods. The study was qualitative and based in the area of the Great Green Wall (GGW) in the region known as Ferlo, northern Senegal. Data were collected by semi-structured interviews in a sample of the population and through discussions with a focus group. It concerned health and aesthetics of the teeth, care and traditional herbal recipes, teeth and superstitions. Results. It appears that people were using the toothpick, the chewing stick and/or charcoal to clean their teeth. Confusion persisted with respect to the types of food consumed that were implicated in the occurrence of dental caries: tea, rice, 'jumbo' (a seasoning spice) and tobacco. 'Borom bop', which means 'master of the head', was the most commonly reported cause of caries. Healthy, beautiful teeth were attributes of beauty and elegance, enhanced by tattoos and crafted crowns in the Fulani. Their health problems were generally managed by healers or traditional practitioners who based their practices on empirical and 'handed down' knowledge. Socio-anthropological meanings were given to children with neonatal teeth. Conclusions. It is therefore important to consider the sociocultural aspects in oral health projects and programmes; the place of herbal medicine in dentistry should be recognized and maybe researched in the region of the Great Green Wall.

Toilet training in Turkey: the factors that affect timing and duration in different sociocultural groups.  

UK PubMed Central (United Kingdom)

BACKGROUND: The aim of the present study was to determine the patterns of toilet training and the factors that may be related to its timing and duration and the approaches of different sociocultural groups within a developing country. METHODS: This cross-sectional survey was performed on 745 children who live in three different sociocultural settlements. The factors that might have affected initiation and completion age and duration of toilet training were assessed with t-test, ANOVA and logistic regression analysis. RESULTS: Mean initiation and completion ages were 22.05 +/- 6.73, 28.05 +/- 8.40 months respectively. The families living in rural and semi-urban settlements, mothers educated for less than 5 years, unoccupied mothers, children living in houses which do not have a toilet inside, families who use washable diapers, who use Turkish style toilets and who use punishment methods started training earlier. In the infants whose mothers had an education over 12 years, completion age was later than others and the earliest completion age was seen in families who used punishment method. Mean duration needed to complete toilet training was 6.84 +/- 7.16 months. The duration of training was longer in families living in rural and semi-urban settlements, mothers educated for less than 5 years, unoccupied mothers, children living in houses which do not have a toilet inside, families who use washable diapers and when the initiation was before the child was 18 months old. CONCLUSION: Toilet training shows differences among cultures. The age of initiation may be increased as the parents are educated better and a child-orientated approach becomes more popular than the parent-orientated approach.

Socio-cultural impacts of construction and regulation of the waterway of Oulujoki river  

International Nuclear Information System (INIS)

[en] The purpose of study was to clarify the socio-cultural impacts of the regulation and construction of Oulujoki river on the everyday life of people. Changes in work and livelihood, living and living satisfaction, and leisure time and recreation are considered as variables. Quantitative and qualitative methods were combined in the study. The principal study material is composed of answers to a questionnaire and of 109 thematic interviews on the topic. The hold of the study is phenomenological-hermeneutical, with the intention to interpret the matter from the viewpoint of the attitudes and requirements of the waterway users. The theoretical frame of reference was culture-ecological point of view and adaptive process. The emphasis of the study is on sociocultural adaptation. The attitude towards waterway construction and regulation was dependent on the background of the person interviewed. The attitude was considered e.g. by various interest groups and professional groups, such as farmers, inhabitants on the shore, recreation users, fishermen, municipal elected officials. Other important variables were age, family stage and sex. Big local differences in the attitudes could also be found. While prevailing values in society and peoples' modes of living are changing, also the attitude towards waterway and changes caused by waterway construction has changed in the region studied. The impacts on the sources of livelihood are minor for the moment, the impacts on living satisfaction and recreations are significant. While leisure time is increasing the recreation value of waterway increases, too. At the construction stage of the river, the economical and productional advantages took priority, and then no attention was paid to recreational use

We present design and first demonstration of optics for a telescopic contact lens with independent optical paths for switching between normal and magnified vision. The magnified optical path incorporates a telescopic arrangement of positive and negative annular concentric reflectors to achieve 2.8 x magnification on the eye, while light passing through a central clear aperture provides unmagnified vision. We present an experimental demonstration of the contact lens mounted on a life-sized optomechanical model eye and, using a pair of modified commercial 3D television glasses, demonstrate electrically operated polarization switching between normal and magnified vision.

Designing a Virtual Manikin Animation Framework Aimed at Virtual Prototyping  

CERN Multimedia

In the industry, numerous commercial packages provide tools to introduce, and analyse human behaviour in the product's environment (for maintenance, ergonomics...), thanks to Virtual Humans. We will focus on control. Thanks to algorithms newly introduced in recent research papers, we think we can provide an implementation, which even widens, and simplifies the animation capacities of virtual manikins. In order to do so, we are going to express the industrial expectations as for Virtual Humans, without considering feasibility (not to bias the issue). The second part will show that no commercial application provides the tools that perfectly meet the needs. Thus we propose a new animation framework that better answers the problem. Our contribution is the integration - driven by need ~ of available new scientific techniques to animate Virtual Humans, in a new control scheme that better answers industrial expectations.

Oftalmologia e realidade virtual Virtual Reality and ophthalmology  

Directory of Open Access Journals (Sweden)

Full Text Available OBJETIVO: Identificar como os simuladores estão sendo usados para ensino, treinamento, terapia e exames na medicina, com destaque para oftalmologia. A realidade virtual surgiu como uma ferramenta auxiliar no ensino e treinamento médico. Na oftalmologia, o progresso dessa técnica tem sido publicado em algumas revistas de saúde. Baseado nessas fontes, investigamos como a Oftalmologia tem interagido com a Realidade Virtual, essa ferramenta que veio para auxiliar o ensino da Medicina. MÉTODOS: Revisão sistemática de artigos das principais revistas, além de livros sobre o assunto entre 1995 e 2010. Revisamos a literatura publicada dos últimos quinze anos baseados em referências mencionadas em várias revistas, como exemplo podemos citar a Medical Education, Journal of the American College of Surgeon, Computers & Graphics, New England Journal of Medicine, Proceedingof the IEEE no período de 1990 a 2010. RESULTADOS: Após a revisão de 200 artigos encontrados sobre o tema educação médica e realidade virtual publicados em revistas nacionais e internacionais entre os anos de 1995 e 2010, percebemos as diferenças entre as áreas da medicina, no que se refere ao uso da realidade virtual (RV). Apenas 10 artigos explicitam com algum aprofundamento os simuladores oftalmológicos. CONCLUSÃO: A oftalmologia é uma das áreas que menos interagem com a realidade virtual, devido a dificuldades de montagem de imagens para serem aplicadas no simulador. Mas é uma das áreas que mais precisa, devido à delicadeza da estrutura de trabalho, olho humano. Assim, a Realidade Virtual (RV) tem aparecido na otoscopia virtual e na formação dos atlas virtuais. Na cirurgia, os simuladores ainda são poucos, mas provavelmente será a área mais promissora, devido as vantagens do treinamento virtual. Assim, a RV tem surgido junto aos serious games, ensino e treinamento de oftalmologia, além de terapia de fobias.OBJECTIVE: To identify how the simulators are being used for education, training, therapy and tests in medicine, particularly ophthalmology.

CONCLUSION: Ophthalmology is one of the areas least interact with virtual reality, due to difficulties of assembling images for application in the simulator. But it is one of the areas most in need, because the delicacy of the work structure, the human eye. Thus, the Virtual Reality (VR) has asparecido in virtual otoscopy and formation of virtual atals. At surgery, the simulators are still few, but will probably be the most promising area because of the advantages of virtual training. Thus, RV has appeared next to serious games, education and training of ophthalmology, and treatment of phobias.

Modeling Virtual Organization Architecture with the Virtual Organization Breeding Methodology  

CERN Document Server

While Enterprise Architecture Modeling (EAM) methodologies become more and more popular, an EAM methodology tailored to the needs of virtual organizations (VO) is still to be developed. Among the most popular EAM methodologies, TOGAF has been chosen as the basis for a new EAM methodology taking into account characteristics of VOs presented in this paper. In this new methodology, referred as Virtual Organization Breeding Methodology (VOBM), concepts developed within the ECOLEAD project, e.g. the concept of Virtual Breeding Environment (VBE) or the VO creation schema, serve as fundamental elements for development of VOBM. VOBM is a generic methodology that should be adapted to a given VBE. VOBM defines the structure of VBE and VO architectures in a service-oriented environment, as well as an architecture development method for virtual organizations (ADM4VO). Finally, a preliminary set of tools and methods for VOBM is given in this paper.

Thermal contact conductance for cylindrical and spherical contacts  

Energy Technology Data Exchange (ETDEWEB)

A prediction methodology based on Monte-Carlo simulation model, developed for flat conforming surfaces in contact, is modified and extended to predict contact conductance between curvilinear surfaces like cylinders and spheres. Experiments are also conducted in vacuum for the measurement of contact conductance between stainless steel and aluminium cylindrical contacts and stainless steel spherical contacts over a range of contact pressures. The contact conductance between cylindrical and spherical bodies is, in general, about an order of magnitude lower than for flat surfaces in contact. Increase of surface roughness and decrease in contact pressure lowers the contact conductance. However, the influence of these parameters is larger than those obtained for flat surfaces. The prediction for different parametric conditions agree closely with those measured in the experiments. (orig.)

During the last years, the problem of allergic diseases has increased. Allergies are errant immune responses to a normally harmless substance. In musicians the allergic contact dermatitis to exotic woods is a special problem. Exotic rosewood contains new flavonoids, which trigger an allergic reaction after permanent contact with the instrument. High quality woodwind instruments such as baroque flute or clarinets are made in ebony or palisander because of its great sound. Today instruments for non-professional players are also made in these exotic materials and non-professionals may have the risk to develop contact dermatitis, too. Brass-player has the risk of an allergic reaction to the different metals contained in the metal sheets of modern flutes and brass instruments. Specially nickel and brass alloys are used to product flute tubes or brass instruments. Special problem arises in children: patients who are allergic to plants or foods have a high risk to develop contact dermatitis. Parents don't know the materials of low-priced instruments for beginners. Often unknown cheap woods from exotic areas are used. Low-priced brass instruments contain high amount of brass and other cheap metals. Physicians should advice musician-patients or parents about the risks of the different materials and look for the reason of eczema on mouth, face, or hands.

[Current contact allergens].  

Science.gov (United States)

Ever-changing exposure to contact allergens, partly due to statutory directives (e.g. nickel, chromate, methyldibromo glutaronitrile) or recommendations from industrial associations (e.g. hydroxyisohexyl 3-cyclohexene carboxaldehyde), requires on-going epidemiologic surveillance of contact allergy. In this paper, the current state with special focus in fragrances and preservatives is described on the basis of data of the Information Network of Departments of Dermatology (IVDK) of the year 2010. In 2010, 12,574 patients were patch tested in the dermatology departments belonging to the IVDK. Nickel is still the most frequent contact allergen. However the continuously improved EU nickel directive already has some beneficial effect; sensitization frequency in young women is dropping. In Germany, chromate-reduced cement has been in use now for several years, leading to a decline in chromate sensitization in brick-layers. Two fragrance mixes are part of the German baseline series; they are still relevant. The most important fragrances in these mixes still are oak moss absolute and hydroxyisohexyl 3-cyclohexene carboxaldehyde. However, in relation to these leading allergens, sensitization frequency to other fragrances contained in the mixes seems to be increasing. Among the preservatives, MCI/MI has not lost its importance as contact allergen, in contrast to MDBGN. Sources of MCI/MI sensitization obviously are increasingly found in occupational context. Methylisothiazolinone is a significant allergen in occupational settings, and less frequently in body care products. PMID:21901563

In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations.

Virtual pinhole confocal microscope  

Energy Technology Data Exchange (ETDEWEB)

Scanned confocal microscopes enhance imaging capabilities, providing improved contrast and image resolution in 3-D, but existing systems have significant technical shortcomings and are expensive. Researchers at Los Alamos National Laboratory have developed a novel approach--virtual pinhole confocal microscopy--that uses state of the art illumination, detection, and data processing technologies to produce an imager with a number of advantages: reduced cost, faster imaging, improved efficiency and sensitivity, improved reliability and much greater flexibility. Work at Los Alamos demonstrated proof of principle; prototype hardware and software have been used to demonstrate technical feasibility of several implementation strategies. The system uses high performance illumination, patterned in time and space. The authors have built functional confocal imagers using video display technologies (LCD or DLP) and novel scanner based on a micro-lens array. They have developed a prototype system for high performance data acquisition and processing, designed to support realtime confocal imaging. They have developed algorithms to reconstruct confocal images from a time series of spatially sub-sampled images; software development remains an area of active development. These advances allow the collection of high quality confocal images (in fluorescence, reflectance and transmission modes) with equipment that can inexpensively retrofit to existing microscopes. Planned future extensions to these technologies will significantly enhance capabilities for microscopic imaging in a variety of applications, including confocal endoscopy, and confocal spectral imaging.

The virtual geometry model  

Energy Technology Data Exchange (ETDEWEB)

The Virtual Geometry Model (VGM) was introduced at CHEP in 2004 [1], where its concept, based on the abstract interfaces to geometry objects, has been presented. Since then, it has undergone a design evolution to pure abstract interfaces, it has been consolidated and completed with more advanced features. Currently it is used in Geant4 VMC for the support of TGeo geometry definition with Geant4 native geometry navigation and recently it has been used in the validation of the G4Root tool. The implementation of the VGM for a concrete geometry model represents a small layer between the VGM and the particular native geometry. In addition to the implementations for Geant4 and Root TGeo geometry models, there is now added the third one for AGDD, which together with the existing XML exporter makes the VGM the most advanced tool for exchanging geometry formats providing 9 ways of conversions between Geant4, TGeo, AGDD and GDML models.

"Child Divorce": A Break from Parental Responsibilities and Rights Due to the Traditional Socio-Cultural Practices and Beliefs of the Parents  

Directory of Open Access Journals (Sweden)

Full Text Available In a recent ground-breaking case the South African courts were for the first time requested to use their discretion to interfere in the parent-child relationship due to the traditional socio-cultural beliefs of the parents. In what has been described as "every parent's nightmare; the fancy of many teenagers", a 16 year-old schoolgirl from Milerton in the Western Cape asked to be "freed" from her parents to live semi-independently from them because of her unhappiness with the conservative manner in which her parents treated her. After considering the matter the judge assigned to the case granted her request to live semi-independently with a school friend and her family (called by the judge the host family) until she reaches the age of 18 (her majority). Her parents were accorded permission to have limited contact with her. This case represents an example of the difficulties involved when balancing the rights of a teenager against those of the parents in matters of socio-cultural practice and belief. In a multi-cultural society such as South Africa the case raises numerous serious questions for other families. For instance, what standards will a court use to determine if parents are too conservative in bringing up their children and what factors will be taken into account? How much freedom and autonomy should children be given? How will courts prevent children from misusing the system just to get what their friends have, and - the ultimate question - are the rights of children superior to the traditional rights of parents in matters of socio-cultural practice, with specific reference to their upbringing? In this context it is the aim of this contribution to focus primarily on the questions asked above. Possible solutions for striking a balance between the rights of children and their parents are explored. The submission is made that the best interests principle is still the most important factor to be taken into account when balancing or weighing competing rights and interests concerning children. The principle of the best interests of the child, the founding principle of children's rights, however, is anchored in the family, and any break between the two should be carefully considered. It is concluded that in an attempt to resolve disputes between parents and their children the relevant provisions of the Constitution and the Children's Act must be considered and must be balanced and tested in relation to each other for constitutional consistency and compliance. It is also submitted that caution should be taken by the legislative framework not to encourage children to break the parent-child relationship on a mere whim, as an overemphasis of children's rights might result in the dilution of the sense of the value of the family in society.

Social Desirability in Virtual Communities  

Directory of Open Access Journals (Sweden)

Full Text Available As virtual worlds and social media in general become important settings for marketing actions, we need to know what is the weight of social norms within such contexts. To what degree can a researcher expect that the answers obtained within a virtual world – ultimately a social network – reflect real opinions and are not inflated by social desirability? Does the social context of an online community induce higher social desirability? This paper investigates whether social desirability is stronger within virtual world online communities than in the real world, observing same structural relationship among measured constructs but higher social desirability tendency in the virtual world compared to the real life. Since social networks and online communities will be more often used as research and communication platforms, increased attention needs to be paid to the social desirability tendency of the community members.

VIRTUAL REALITY AND PUBLIC ADMINISTRATION  

Directory of Open Access Journals (Sweden)

Full Text Available This study serves as an introduction to how virtual reality systems could be applied in public administration and what research tasks would be necessary to accomplish a project. E-government solutions began to emerge in public administration approximately a decade ago all over the developed world. Administration service facilities via the Internet did not attract many customers, because of the digital divide. E-government solutions were extended to mobile devices as well, but the expected breakthrough of usage has not ensued. The virtual reality form of public administration services recommended in this study has the most attractive outlay and the simplest navigation tools if compared to ‘traditional’ Internet based e-government. Thus, in accordance with the worldwide amazingly quick spread of the virtual reality systems of Second Life and 3 D types of entertainment, virtual reality applications in public administration could rely on a wide range of acceptance as well.

Weak Deeply Virtual Compton Scattering  

Energy Technology Data Exchange (ETDEWEB)

We extend the analysis of the deeply virtual Compton scattering process to the weak interaction sector in the generalized Bjorken limit. The virtual Compton scattering amplitudes for the weak neutral and charged currents are calculated at the leading twist within the framework of the nonlocal light-cone expansion via coordinate space QCD string operators. Using a simple model, we estimate cross sections for neutrino scattering off the nucleon, relevant for future high intensity neutrino beam facilities.

Teaching professionalism through virtual means.  

UK PubMed Central (United Kingdom)

OBJECTIVES: Virtual patients are used across a variety of clinical disciplines for both teaching and assessment, but are they an appropriate environment in which to develop professional skills? This study aimed to evaluate students' perceived effectiveness of an online interactive virtual patient developed to augment a personal professional development curriculum, and to identify factors that would maximise the associated educational benefits. METHODS: Student focus group discussions were conducted to explore students' views on the usefulness and acceptability of the virtual patient as an educational tool to teach professionalism, and to identify factors for improvement. A thematic content analysis was used to capture content and synthesise the range of opinions expressed. RESULTS: Overall there was a positive response to the virtual patient. The students recognised the need to teach and assess professionalism throughout their curriculum, and viewed the virtual patient as a potentially engaging and valuable addition to their curriculum. We identified factors for improvement to guide the development of future virtual patients. CONCLUSION: It is possible to improve approaches to teaching and learning professionalism by exploring students' views on innovative teaching developments designed to augment personal professional development curricula.

The pathology of soft contact lens spoilage.  

UK PubMed Central (United Kingdom)

Our study of a random series of more than 300 spoiled soft contact lenses reveals that virtually all lenses currently in use for daily or extended wear are subject to deterioration due to extraneous deposits, physical and chemical changes in the lens material, and microbial invasion. Common causes include ocular secretions, finger dirt and cosmetics, disinfecting and cleansing techniques, environmental factors, manufacturing defects and polymer impurities, mechanical stress and breakage, as well as aging and decay of the lens material. Mucoprotein-lipid deposits, with or without calcium, and calcareous deposits constitute the major forms of lens spoilage. Removal of encrusted deposits leaves surface irregularities and matrix defects which facilitate secondary spoilage including microbial invasion, and such lenses should be discarded. As virtually no soft lens material currently in use is "safe" for extended wear, the practitioner must carefully evaluated and follow his patients to identify those at risk of lens failure and spoilage complications. To eliminate spoilage, new lens materials and improved manufacturing techniques are needed. In the interim, for many patients, an inexpensive disposable soft lens which can be easily replaced, perhaps weekly or bi-weekly, may be the answer.

Integration of a Balanced Virtual Manikin in a Virtual Reality Platform aimed at Virtual Prototyping  

CERN Multimedia

The work presented here is aimed at introducing a virtual human controller in a virtual prototyping framework. After a brief introduction describing the problem solved in the paper, we describe the interest as for digital humans in the context of concurrent engineering. This leads us to draw a control architecture enabling to drive virtual humans in a real-time immersed way, and to interact with the product, through motion capture. Unfortunately, we show this control scheme can lead to unfeasible movements because of the lack of balance control. Introducing such a controller is a problem that was never addressed in the context of real-time. We propose an implementation of a balance controller, that we insert into the previously described control scheme. Next section is dedicated to show the results we obtained. Finally, we propose a virtual reality platform into which the digital character controller is integrated.

Framed knot contact homology  

CERN Multimedia

We extend knot contact homology to a theory over the ring $\\Z[\\lambda^{\\pm 1},\\mu^{\\pm 1}]$, with the invariant given topologically and combinatorially. The improved invariant, which is defined for framed knots in $S^3$, can distinguish many pairs of knots, including mutants, and can also be defined for knots in arbitrary manifolds. It contains the Alexander polynomial and naturally produces a two-variable polynomial knot invariant which is related to the $A$-polynomial.

Contact dermatitis in children  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Contact dermatitis in pediatric population is a common but (previously) under recognized disease. It is usually divided into the allergic and the irritant forms. The diagnosis is usually obtained with the patch test technique after conducting a thorough medical history and careful physical examination but patch testing in infants may be particularly difficult, and false-positive reactions may occur. This study also provides an overview of the most common allergens in pediatric population and discusses various therapeutic modalities.

Knot contact homology  

CERN Document Server

The conormal lift of a link $K$ in $\\R^3$ is a Legendrian submanifold $\\Lambda_K$ in the unit cotangent bundle $U^* \\R^3$ of $\\R^3$ with contact structure equal to the kernel of the Liouville form. Knot contact homology, a topological link invariant of $K$, is defined as the Legendrian homology of $\\Lambda_K$, the homology of a differential graded algebra generated by Reeb chords whose differential counts holomorphic disks in the symplectization $\\R \\times U^*\\R^3$ with Lagrangian boundary condition $\\R \\times \\Lambda_K$. We perform an explicit and complete computation of the Legendrian homology of $\\Lambda_K$ for arbitrary links $K$ in terms of a braid presentation of $K$, confirming a conjecture that this invariant agrees with a previously-defined combinatorial version of knot contact homology. The computation uses a double degeneration: the braid degenerates toward a multiple cover of the unknot which in turn degenerates to a point. Under the first degeneration, holomorphic disks converge to gradient flow ...
