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?

Contact-based ligand-clustering approach for the identification of active compounds in virtual screening  

Directory of Open Access Journals (Sweden)

Full Text Available Alexey B Mantsyzov,1 Guillaume Bouvier,2 Nathalie Evrard-Todeschi,1 Gildas Bertho11Université Paris Descartes, Sorbonne, Paris, France; 2Institut Pasteur, Paris, FranceAbstract: Evaluation of docking results is one of the most important problems for virtual screening and in silico drug design. Modern approaches for the identification of active compounds in a large data set of docked molecules use energy scoring functions. One of the general and most significant limitations of these methods relates to inaccurate binding energy estimation, which results in false scoring of docked compounds. Automatic analysis of poses using self-organizing maps (AuPosSOM represents an alternative approach for the evaluation of docking results based on the clustering of compounds by the similarity of their contacts with the receptor. A scoring function was developed for the identification of the active compounds in the AuPosSOM clustered dataset. In addition, the AuPosSOM efficiency for the clustering of compounds and the identification of key contacts considered as important for its activity, were also improved. Benchmark tests for several targets revealed that together with the developed scoring function, AuPosSOM represents a good alternative to the energy-based scoring functions for the evaluation of docking results.Keywords: scoring, docking, virtual screening, CAR, AuPosSOM

Sociocultural determinants of induced abortion  

International Nuclear Information System (INIS)

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) abortion. (author)

Cognitive abilities, sociocultural background and academic achievement.  

Science.gov (United States)

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.

A Sociocultural Approach to Recognition and Learning  

Directory of Open Access Journals (Sweden)

Full Text Available This is a case study of goldsmith craft apprenticeship learning and recognition. The study includes 13 participants in a goldsmith's workshop. The theoretical approach to recognition and learning is inspired by sociocultural theory. In this article recognition is defined with reference to Hegel’s understanding of the concept as a transformed struggle of granting acknowledgement to another person plus receiving acknowledgement as a person. It is argued that the notion of recognition can enhance sociocultural notions of learning. In analysing the case study of apprenticeship learning, the article suggests that recognition is expressed in the act of participants staking their lives to prove their autonomy, in work activity in terms of the role of artefacts and in the form of abstract and concrete recognition. Finally recognition is discussed in relation to learning and development. The study concludes that recognition is an important category not only to explain apprenticeship learning but also to give a sociocultural explanation of learning in general.

Sociocultural context of women's body image.  

Science.gov (United States)

In our society, women's bodies are the locus of both increasing rates of obesity and body dissatisfaction. While these trends may seem contradictory or to result from each other, an alternative explanation is that they are both the products of an unfavourable sociocultural environment in the area of food and weight. Both body dissatisfaction and excess weight can seriously impact women's physical and emotional health. The strong cultural value placed on thinness, especially for women, unfortunately may take precedence over health. To effectively address the impact of women's body image dissatisfaction requires an understanding of the multiple contexts of women's lives. This study used a naturalistic paradigm to explore how women's personal and sociocultural context influences their body image. Forty-four non-eating disordered women ranging from 21 to 61 years old were interviewed twice using a semi-structured interview guide. Women's narratives revealed that body image is not a static construct, but is dynamic and fluctuates as women encounter new experiences and re-interpret old ones. The powerful and unconscious impact of the media on body image was mediated by women's internal contexts (self-confident and self-critical) and their relationships with others, such as partners and other women. Body image was not so much influenced by the nature of others' comments but interpretation of their meaning. However, health professionals' comments were typically not reinterpreted due to the health context in which they were given. While some women's narratives expressed their internalized sociocultural norms, others' described acceptance of their bodies following a process of reflection and empowerment. In light of these findings, efforts to improve women's body image, and by extension their health, can no longer only focus on diminishing the tangible power of industry and media, but must include transforming the social ties, practices and conventions in everyday relationships, including with health professionals.

The methodology incorporates hermeneutic-phenomenology, reflexive inquiry, and event-oriented inquiry. Research on emotions contextualizes methodologies for multidisciplinary and multi-level research. Finally, a new journal that was developed as a home for cultural studies of science education is described along with the processes used in manuscript review and publication.

Sociocultural Perspectives on Foreign Language Learning  

Directory of Open Access Journals (Sweden)

Full Text Available This paper aims at presenting a brief overview of the major theoretical claims of the sociocultural theory (SCT of mind and mental development with particular attention to how it relates to the learning and teaching of second/foreign languages. The sociocultural perspective has profound implications for teaching, schooling, and education. The main idea of this psychological view of human development is that social interaction is responsible for the development of higher order functions. In this regard it is believed that just the individual’s internal cognitive process cannot account for developmental process. The researchers should also consider the external social factors in the child’s environment. Children participate in activities which entail the use of cognitive and communicative functions and by doing so, these functions scaffold and nurture them in their developmental process. Hence in language classrooms successful instructions should be within the child’s zone of proximal development (ZPD and also successful learning process cannot be an individual’s unmediated or unassisted effort but a collaborative process.

Extending the Individual Level of Virtuality: Implications of Task Virtuality in Virtual and Traditional Settings  

Directory of Open Access Journals (Sweden)

Full Text Available Virtuality in organizations has usually been treated as a characteristic that is observed either at a team or organizational level. However, the penetration of new technologies into our lives has transformed the entire design of organizations and teams. Not only has the design of teams and organizations changed, but the context and design of our jobs have also been impacted. Today, even employees in traditional team settings use electronic communication tools to work with multiple dispersed contacts outside of their teams and organizations, such as colleagues, clients or suppliers, who do not share the same geographical location. With all of these changes, virtuality can no longer be considered as a concept that is exclusive to virtual team members. In today’s organizations, to some extent, everyone’s tasks involve non-face-to-face contacts, irrespective of team virtuality. It therefore becomes crucial to identify the task virtuality phenomenon in organizations. With this paper, the example of Yahoo! is used as a case study to illustrate how task virtuality can be relevant for the design of organizations. Additionally, the proposed two-dimensional framework integrates both team virtuality and task virtuality elements in organizations. This framework is novel in that it not only allows us how to conceptualize the task virtuality, but also provides practical guidance for managers to identify and understand the factors leading to high task virtuality and to deal with the resulting complexities.

Sociocultural factors in Brazilian neuropsycholinguistic studies  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english 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 bronchoscopy  

International Nuclear Information System (INIS)

Flexible bronchoscopy represents a clinically well-established invasive diagnostic tool. Virtual bronchoscopies, calculated from thin-slice CT sections, allow astonishing immitations of reality although principal differences exist between both technologies: the Fact that colour representation is artificial and concommitant interventions are impossible limits the clinical use of virtual bronchoscopy. However, its value increases when calculations can be attained within minutes due to technological advancements, and when virtually any chest CT is suitable for further postprocessing. Indications, findings and the clinical role of virtual bronchoscopy are discussed. (orig.)

Virtual Laboratories and Virtual Worlds  

CERN Document Server

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 Labs and Virtual Worlds  

Science.gov (United States)

Virtual Labs and Virtual Worlds Coastline Community College has under development several virtual lab simulations and activities that range from biology, to language labs, to virtual discussion environments. Imagine a virtual world that students enter online, by logging onto their computer from home or anywhere they have web access. Upon entering this world they select a personalized identity represented by a digitized character (avatar) that can freely move about, interact with the environment, and communicate with other characters. In these virtual worlds, buildings, gathering places, conference rooms, labs, science rooms, and a variety of other “real world” elements are evident. When characters move about and encounter other people (players) they may freely communicate. They can examine things, manipulate objects, read signs, watch video clips, hear sounds, and jump to other locations. Goals of critical thinking, social interaction, peer collaboration, group support, and enhanced learning can be achieved in surprising new ways with this innovative approach to peer-to-peer communication in a virtual discussion world. In this presentation, short demos will be given of several online learning environments including a virtual biology lab, a marine science module, a Spanish lab, and a virtual discussion world. Coastline College has been a leader in the development of distance learning and media-based education for nearly 30 years and currently offers courses through PDA, Internet, DVD, CD-ROM, TV, and Videoconferencing technologies. Its distance learning program serves over 20,000 students every year. sponsor Jerry Meisner

La salud pública. Un fenómeno sociocultural complejo  

Directory of Open Access Journals (Sweden)

Full Text Available El tema de la salud, es recurrente en las ciencias del hombre. Es lógico, pues se trata de un problema sensible que de una forma u otra preocupa a toda la humanidad. Es consustancial a su ser esencial, a su conciencia de finitud y sus ansias de trascendencia. La salud no es sólo ausencia de enfermedad y condición que aleja la muerte. Ese final que tanto tememos y que la ciencia intenta vencer. La salud es mucho más. No es sólo la sana existencia. Es el vivir a plenitud, tanto desde el punto de vista social como material y espiritual. Por ello, referirse a la salud es remitirse a uno de esos problemas que hoy día la ciencia ubica como fenómeno complejo y multidisciplinario. Dicha denominación no desecha su esencia contradictoria; al contrario, revela con fuerza las múltiples mediaciones, determinaciones y condicionamientos que le son inmanentes, y que hacen que devenga en un sistema complejo. Este abordaje de la salud determina que estemos en presencia de un problema de naturaleza biológico y sociocultural, que las ciencias de la salud y otras disciplinas no deben soslayar. Por esta misma razón, el estudio de la salud pública, definida por las características y condiciones de salud presentes en los grupos sociales en distintos niveles de análisis: comunitario; municipal; estatal; regional; nacional e internacional, debe darse a partir de una perspectiva multidisciplinaria y transdisciplinaria, en la cual los conceptos de atención primaria; promoción de la salud; modo de vida y estilo de vida, en tanto elementos determinantes y condicionantes de los niveles de salud de la población, deberían constituir los aspectos prioritarios de toda política pública sanitaria.

Virtual seminars  

Science.gov (United States)

A virtual seminar (SM) is an economic and effective instructional tool for teaching students who are at a distance from their instructor. Like conventional class room teaching, a virtual seminar requires an instructor, a student, and a method of communication. Teleconferencing, video conferencing, intranets and the Internet give learners in a Virtual Seminar the ability to interact immediately with their mentors and receive real and relevant answers. This paper shows how industry and academia can benefit from using methods developed and experience gained in presenting the first virtual seminars to academic and petroleum industry participants in mid-1996. The information explosion in industry means that business or technical information is worthless until it is assimilated into a corporate knowledge management system. A search for specific information often turns into a filtering exercise or an attempt to find patterns and classify retrieved material. In the setting of an interactive corporate information system, virtual seminars meet the need for a productive new relationship between creative people and the flux of corporate knowledge. Experience shows that it is more efficient to circulate timesensitive and confidential information electronically through a virtual seminar. Automating the classification of information and removing that task from the usual work load creates an electronic corporate memory and enhances the value of the knowledge to both users and a corporation. Catalogued benchmarks, best-practice standards, and Knowledge Maps (SM) of experience serve as key aids to communicating knowledge through virtual seminars and converting that knowledge into a profit-making asset.

Virtual Quarry  

Science.gov (United States)

This interactive virtual tour for younger students lets them 'drive' a quarry truck and visit a rock quarry to see how the rock is mined, processed and transported, and what the aggregate is used for. The tour includes safety tips for visiting quarries. They can also 'restore' an abandoned quarry by planting virtual grass, reeds, and trees, view movies about quarries, and use a virtual microscope to look at some rock samples. There are also links to lesson plans on the use and restoration of quarries.

Sociocultural influences and self-care practices of middle adolescents.  

Science.gov (United States)

The purpose of this study was to describe general self-care practices of middle adolescents. In addition, the relation between general self-care practices and specific sociocultural characteristics including socioeconomics and church attendance were explored. Orem's self-care theory and developmental theory provided the framework for the investigation. Findings from the sample of 15- and 16-year-old adolescents (n = 425) showed that they are engaging in self-care practices. The influence of sociocultural characteristics on self-care practices was supported. Implications from the study include the need to continue research endeavors that describe, explain, and predict health behavior in child and adolescent populations. Practicing nurses in diverse health care settings should consider the results of this study when working with adolescents and their families from diverse sociocultural backgrounds. Results from this investigation should be incorporated into the planning of health education programs for the adolescent population. PMID:10714036

DESIGN, EVALUATION AND SYSTEMATIZATION OF PROJECTS OF COMMUNITY SOCIOCULTURAL TRANSFORMATION / DISEÑO, EVALUACIÓN Y SISTEMATIZACIÓN DE PROYECTOS DE TRANSFORMACIÓN SOCIOCULTURAL COMUNITARIA  

Directory of Open Access Journals (Sweden)

Full Text Available The projects of socio-cultural transformation as a way of materializing the social and cultural policies are made up to satisfy the population’s needs. These are the operational translation of those policies. The imperative of this way looking-up is to increase the socio-cultural and the efficiency impacts on the implementation of those policies. In Cuban experience, the looking-up of projects has had positive results for the socio-cultural development as in the different territories as in institutions. A way through which can be fulfilled a communitarian transformation is by means of the execution of socio-cultural transformation projects, which are considered as proposal of solution to situations that exist in the socio-cultural reality. They are constituted by a set of activities which are carried out co-ordinately to fulfil the objective in a certain period of time; the importance of this matter has influenced in the determination of the following research.

Virtual Specimens  

Science.gov (United States)

Virtual Field Trips have been around almost as long as the Worldwide Web itself yet virtual explorers do not generally return to their desktops with folders full of virtual hand specimens. Collection of real specimens on fields trips for later analysis in the lab (or at least in the pub) has been an important part of classical field geoscience education and research for generations but concern for the landscape and for preservation of key outcrops from wanton destruction has lead to many restrictions. One of the author’s favorite outcrops was recently vandalized presumably by a geologist who felt the need to bash some of the world’s most spectacular buckle folds with a rock sledge. It is not surprising, therefore, that geologists sometimes leave fragile localities out of field trip itineraries. Once analyzed, most specimens repose in drawers or bins, never to be seen again. Some end up in teaching collections but recent pedagogical research shows that undergraduate students have difficulty relating specimens both to their collection location and ultimate provenance in the lithosphere. Virtual specimens can be created using 3D modeling software and imported into virtual globes such as Google Earth (GE) where, they may be linked to virtual field trip stops or restored to their source localities on the paleo-globe. Sensitive localities may be protected by placemark approximation. The GE application program interface (API) has a distinct advantage over the stand-alone GE application when it comes to viewing and manipulating virtual specimens. When instances of the virtual globe are embedded in web pages using the GE plug-in, Collada models of specimens can be manipulated with javascript controls residing in the enclosing HTML, permitting specimens to be magnified, rotated in 3D, and sliced. Associated analytical data may be linked into javascript and localities for comparison at various points on the globe referenced by ‘fetching’ KML. Virtual specimens open up new possibilities for distance learning, where design of effective lab exercises has long been an issue, and they permit independent evaluation of published field research by reviewers who do not have access to the physical field area. Although their creation can be labor intensive, the benefits of virtual specimens for education and research are potentially great. Interactive 3D Specimen of Sierra Granodiorite at Outcrop Location

California Virtual Campus  

Science.gov (United States)

California Virtual Campus is essentially a catalog of every virtual or technology-mediated distance education course or program offered by participating California colleges and universities. Users can search for a particular course or find information about pursuing a complete program of study from certificate level to PhD. The site summarizes important information about each course or program, such as in-state and out-of-state fees, email contacts, and registration details. For example, a search returned a list of 30 art-related course offerings at about 20 different institutions. By clicking on a title, "Visionary Artists: A Brief History of Multimedia," I found I could take this course, offered by San Francisco State University, by registering and paying a fee of $5.

Intelligent virtual interfaces for telerobotics  

Science.gov (United States)

One promise of telerobotics is the ability to interact in environments that are distant (e.g., deep sea or deep space), dangerous (e.g., nuclear, chemical, or biological environments), or inaccessible by humans for political or legal reasons. A key component to such interactions are sophisticated human-computer interfaces that can replicate sufficient information about a local environment to permit remote navigation and manipulation. This environment replication can, in part, be provided by technologies such as virtual reality. In addition, however, telerobotic interfaces may need to enhance human-machine interaction to assist users in task performance, for example, governing motion or manipulation controls to avoid obstacles or to restrict interaction with certain objects (e.g., avoiding contact with a live mine or a deep sea treasure). Thus, effective interactions within remote environments require intelligent virtual interfaces to telerobotic devices. In part to address this problem, MITRE is investigating virtual reality architectures that will enable enhanced interaction within virtual environments. Key components to intelligent virtual interfaces include spoken language processing, gesture recognition algorithms, and more generally, task recognition. In addition, these interfaces will eventually have to take into account properties of the user, the task, and discourse context to be more adaptive to the current situation at hand. While our work has not yet investigated the connection of virtual interfaces to external robotic devices, we have begun developing the key components for intelligent virtual interfaces for information and training systems.

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  

International Nuclear Information System (INIS)

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

Virtual Sustainability  

Directory of Open Access Journals (Sweden)

Full Text Available In four ways, massively multiplayer online role-playing games may serve as tools for advancing sustainability goals, and as laboratories for developing alternatives to current social arrangements that have implications for the natural environment. First, by moving conspicuous consumption and other usually costly status competitions into virtual environments, these virtual worlds might reduce the need for physical resources. Second, they provide training that could prepare individuals to be teleworkers, and develop or demonstrate methods for using information technology to replace much transportation technology, notably in commuting. Third, virtual worlds and online games build international cooperation, even blending national cultures, thereby inching us toward not only the world consciousness needed for international agreements about the environment, but also toward non-spatial government that cuts across archaic nationalisms. Finally, realizing the potential social benefits of this new technology may urge us to reconsider a number of traditional societal institutions.

Contact problems  

CERN Document Server

L.A. Galin's book on contact problems is a remarkable work. Actually there are two books: the first, published in 1953 deals with contact problems in the classical theory of elasticity; this is the one that was translated into English in 1961. The second book, published in 1980, included the first, and then had new sections on contact problems for viscoelastic materials, and rough contact problems; this section has not previously been translated into English. In this new translation, the original text and the mathematical analysis have been completely revised, new material has been added, and the material appearing in the 1980 Russian translation has been completely rewritten. In addition there are three essays by students of Galin, bringing the analysis up to date.

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.

The Discovery Channel's website has several interactive features on volcanoes to complement its programs on Pompeii. At the homepage, visitors can explore a virtual volcano, by clicking on "Enter". The virtual volcano has several components. The first is a quickly revolving globe with red triangles and gray lines on it that represent active volcanoes and plate boundaries. Clicking on "Stop Rotation", located next to the globe, will enable a better look. Visitors can also click one of the topics below the globe, to see illustrations of "Tectonic Plates", "Ring of Fire" (no, not the Johnny Cash song), and "Layers Within". Visitors can click on "Build your Own Volcano and Watch it Erupt" on the menu on the left side of the page, where they will be given a brief explanation of two factors that affect the shape and explosiveness of volcanoes: viscosity and gas. Then they must choose, and set, the conditions of their volcano by using the arrows under the viscosity and gas headings, and clicking on "Set Conditions", underneath the arrows. Once done, a description of the type of volcano created will be given, and it's time to "Start Eruption". While the lava flows, and the noise of an eruption sounds, terms describing various features of the volcano are superimposed on the virtual volcano, and can be clicked on for explanations.

[Virtual colonoscopy].  

Science.gov (United States)

Colorectal cancer is a leading cause of cancer death in the western world. Virtual colonoscopy is a new method for 2-D and 3-D imaging of the colon, using a multislice helical CT technology. This method has already demonstrated excellent results in polyp and cancer detection, having similar accuracy to endoscopic colonoscopy in the detection of polyps above 6 mm in size. The major application of this novel technique is in diagnosing cases where conventional colonoscopy fails to demonstrate the entire colon due to technical problems. The second important application is to investigate the colon proximal to an obstructing tumor, where both barium enema and colonoscopy cannot overcome the obstruction. The possibility of widespread application remains in evaluating the use of virtual colonoscopy in a purely screening population. Further developments, including stool tagging, computer aided detection of polyps and faster scanners will contribute to accuracy and patient compliance with widespread use of virtual colonoscopy. This examination may dramatically improve population participation in screening programs and play a major role in minimizing the impact of colorectal cancer. PMID:12362486

Virtual Cystoscopy  

International Nuclear Information System (INIS)

Introduction: virtual cystoscopy is a minimally invasive procedure that facilitates the evaluation of the urinary tract, allowing intraluminal navigation through the urinary tract structures on the basis of CT imaging reconstructions. it allows detection of various pathologies of the system, through high-sensitivity, three-dimensional lesion visualization with some advantages over conventional cystoscopy. Objective: to describe the technique used for virtual cystoscopy at our institution,and present some representative cases. Materials and methods: We describe the main indications, advantages and limitations of the method, followed by a description of the technique used in our institution, and finally, we present five representative cases of bladder and urethral pathology. Conclusion: virtual cystoscopy is a sensitive technique for the diagnosis of bladder tumors, even those smaller than 5mm. it is the preferred method in patients who have contraindications for conventional cystoscopy, such as prostate hyperplasia, urethral stenoses and active haematuria.it is less invasive and has a lower complication rate when compared with conventional cystoscopy. It has limited use in the assessment of the mucosa and of small, flat lesions.

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  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish 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 implementació [...] n de dichas estrategias analizando la adaptación psicológica, la sociocultural, la académica, la satisfacción vital y la discriminación percibida. Se tomó en cuenta 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 p [...] urpose 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 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

A Animação Sociocultural e a Formação Profissional em Turismo: reflexões sobre a animação turística  

Directory of Open Access Journals (Sweden)

Full Text Available Resumo O presente texto traz alguns pontos-chave que são característicos das atuais discussões sobre a Animação Sociocultural, e tem como objetivo contribuir com as reflexões sobre a mesma e também discutir elementos para se observar a experiência turística. A importância dessas idéias reside na necessidade de ampliar os debates sobre a Animação Sociocultural, buscando um repensar sobre a Animação Turística. Para tal intuito, utilizou-se pesquisa bibliográfica tendo como temas centrais a Animação Sociocultural, o Turismo e a Formação Profissional em Turismo. Ao final, espera-se que a proposta de articular a Animação Sociocultural e a Animação Turística não fragmente a Animação Sociocultural, mas sim incentive outros campos do saber a fornecer mais subsídios para a configuração da própria. Palavras-chave: animação sociocultural; turismo; animação turística; formação profissional. Abstract The present text brings some key points that are characteristics of the current discussions on Sociocultural Animation. It also approaches aspects referring to the field of tourism and it has the pretension of contributing to the reflections on it and simultaneously bringing new elements to observe the tourist experience. The importance of these ideas lies on the need of broadening the debates on Sociocultural Animation and on the possibility of showing the Tourist Animation as a relevant construct to reflections/ intervention. A bibliographical research centered on Sociocultural Animation and Tourism was used as means to this end. At the end, we hope that the proposal of establishing a narrower relation between the two animations does not stimulate the fragmentation of Sociocultural. On the contrary, we hope it will stimulate other fields of knowledge to contribute to the configuration of Sociocultural Animation. Keywords: sociocultural animation; tourism; tourist animation; professional formation.

The Potential for Vygotskian Sociocultural Perspective in Researching Researcher Development  

Directory of Open Access Journals (Sweden)

Full Text Available This paper builds on the recently emerged scholarship of researcher development and considers a potential conceptual framework to inform methodology in research on researcher development. Specifically, I begin by examining the knowledge base of researcher development and discussing a recently proposed agenda for research in the field. I then argue that there is a particular need for a conceptual framework to underpin research on researcher development and consider the potential of a framework that draws upon Vygotskian sociocultural and activity theory. At the end of the paper, I present analysis of qualitative data from existing researcher development literature to illustrate how this framework can be applied empirically.

A Socio-cultural Perspective on Patient Safety  

CERN Document Server

This edited volume of original chapters brings together researchers from around the world who are exploring the facets of health care organization and delivery that are sometimes marginal to mainstream patient safety theories and methodologies but offer important insights into the socio-cultural and organizational context of patient safety. By examining these critical insights or perspectives and drawing upon theories and methodologies often neglected by mainstream safety researchers, this collection shows we can learn more about not only the barriers and drivers to implementing patient safety

Thermal Contact  

Directory of Open Access Journals (Sweden)

Full Text Available The concepts of temperature and entropy as applied in equilibrium thermodynamics do not easily generalize to nonequilibrium systems and there are transient systems where thermodynamics cannot apply. However, it is possible that nonequilibrium steady states may have a thermodynamics description. We explore the consequences of a particular microscopic thermostat-reservoir contact needed to both stabilize and measure the temperature of a system. One particular mechanical connection mechanism is considered in detail and a contact resistance is observed in the numerical simulations. We propose a microscopic mechanism to explain this effect for both equilibrium and nonequilibrium systems. These results emphasize the difficulty in identifying a microscopic expression for the thermodynamic temperature. It is evident that the kinetic temperature is not necessarily equal to the thermodynamic temperature, especially when used to define the local temperature.

EL CARÁCTER SOCIOCULTURAL DE LA ENSEÑANZA EN LA EDUCACIÓN SUPERIOR (THE SOCIOCULTURAL NATURE OF TEACHING IN HIGHER EDUCATION  

Directory of Open Access Journals (Sweden)

Full Text Available Resumen:Como la escuela en general, el ámbito de la educación superior también nos ofrece un escenario privilegiado para recabar evidencias del carácter sociocultural del pensamiento. Fundada en las exploraciones de Vigotzky y expandida por sus seguidores, la perspectiva sociocultural establece que nuestro pensamiento en general, y las funciones mentales superiores en particular, están por definición culturalmente mediados; y que no hay forma de no estar culturalmente situados cuando llevamos a cabo una acción, usualmente acorde con los patrones aceptados por el grupo social al que se pertenece (acción mediada. A partir de estas aseveraciones, este ensayo intenta justificar la importancia de un mayor conocimiento del contexto cultural que tiene lugar al interior de la educación superior, y una mejor comprensión de las implicaciones que las diferencias disciplinarias tienen en la enseñanza y el aprendizaje; dar cuenta de algunos hallazgos de incursiones de la investigación empírica a este respecto; y cerrar enmarcando los aportes concretos de este ejercicio dentro de una eminente preocupación por encontrar nuevas formas de articular la multiculturalidad; de integrar la diversidad que nos habita y nos estructura, y que forma parte de nuestras herencias y de nuestro presente cultural.Abstract:Just like school does in a general sense, higher education creates a privileged setting for collecting evidences of the sociocultural nature of thinking. Grounded in Vygotsky’s explorations and extended by his colleagues, the sociocultural perspective establishes that our thinking in a broad sense, and higher psychological functioning in particular, are by definition culturally mediated; and that there is no other way than to be culturally situated when taking action, usually following patterns accepted by the social group to which one belongs (mediated action. Parting from those statements, this essay attempts to justify the importance of a better understanding of the higher education’s cultural context, the implications that disciplinary differences have both for teaching and for learning; also to take into consideration some empirical research findings in the field. All this with a great concern for finding alternatives to promote interdisciplinary dialogue; and ways to understand the diversity that surrounds us and gives us structure; diversity which is part of our natural inheritance and our cultural present.

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.

Virtual Titanic  

Science.gov (United States)

The recent historical and cinematic fascination with the Titanic proves that the allure of this most famous luxury liner remains unsinkable. The Discovery Channel Online has created a captivating site devoted to images, movies (IPIX, QuickTime), and text describing the ship and its demise. While the site contains historical photos and lithographs of the ship as well as underwater photos and movies from a 1985 submersible mission, the unique contribution of this site is its numerous virtual images of the interior and exterior of the Titanic as well as its movies of the collision and sinking. Developed by Andrew Nelson for a CD-ROM game, the movies include a flyby of the ship, a collision movie, a listing movie, and a three-part series of the sinking. Both flat and "bubble" views of such features as the first-class cabins, the wireless room, and the grand staircase are also included. A talk-back section discusses various theories surrounding the sinking and contains several related links.

These practices can be found in the local media, causing them to participate in the formation of a border culture. The constant traffic of people and symbolic and material goods contribute to the sedimentation of a de facto Latin American integrationist process.

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).

El aspecto socio-cultura del pensamiento y del lenguaje: visión Vygotskyana / The socio-cultural aspect of thought and language: the vygotskyan vision

Full Text Available SciELO Venezuela | Language: Spanish Abstract in spanish Una premisa básica de la teoría vygotskyana es la de que toda forma de actividad mental humana de orden superior es derivada de contextos sociales y culturales y que la misma es compartida por los miembros de ese contexto debido a que estos procesos mentales son ajustables. De acuerdo con la teoría [...] sociocultural de Vygotsky, el conocimiento es un fenómeno profundamente social y este fenómeno moldea las formas que el individuo tiene disponibles para pensar e interpretar el mundo. En esta experiencia el lenguaje juega un papel fundamental en una mente formada socialmente porque es nuestra primera vía de contacto mental y de comunicación con otros y representa una herramienta indispensable para el pensamiento. Por considerar que el lenguaje representa un puente muy importante entre el mundo sociocultural y el funcionamiento mental del individuo, Vygotsky calificó la adquisición del lenguaje como la piedra angular del desarrollo cognoscitivo del niño Abstract in english A basic premise of the vygotskyan theory is that every form of human mental activity of superior order derives from social and cultural contexts, and since these mental processes are adjustable, it is shared by the members of that context. According to Vygotsky ’s socio-cultural theory, knowledge is [...] a deeply social phenomenon and this phenomenon molds the ways a person has available to interpret and think about the world. Language plays an important role in a socially educated mind during this experience because it is our first way of mental contact and communication with others and represents an indispensable tool for thinking. Considering that language represents a very important bridge between the socio-cultural world and the individual ’s mental functioning, Vygotsky qualified language acquisition as the cornerstone of children ’s cognositive development

Creating opportunities to learn in mathematics education: a sociocultural perspective  

Science.gov (United States)

The notion of `opportunities to learn in mathematics education' is open to interpretation from multiple theoretical perspectives, where the focus may be on cognitive, social or affective dimensions of learning, curriculum and assessment design, issues of equity and access, or the broad policy and political contexts of learning and teaching. In this paper, I conceptualise opportunities to learn from a sociocultural perspective. Beginning with my own research on the learning of students and teachers of mathematics, I sketch out two theoretical frameworks for understanding this learning. One framework extends Valsiner's zone theory of child development, and the other draws on Wenger's ideas about communities of practice. My aim is then to suggest how these two frameworks might help us understand the learning of others who have an interest in mathematics education, such as mathematics teacher educator-researchers and mathematicians. In doing so, I attempt to move towards a synthesis of ideas to inform mathematics education research and development.

Full Text Available La premisa central de la teoría vygotskiana es que para promover el aprendizaje y, consecuentemente, el desarrollo, es necesario intervenir en el contexto socio-cultural y transformarlo. Una interpretación errónea de la teoría histórico-cultural de Vygotsky ha llevado a decir lo contrario y ha abogado por la adaptación de la enseñanza al contexto, aumentando el fracaso escolar. Este artículo ofrece evidencias del verdadero sentido transformador de la teoría de Vygotsky y muestra cómo los centros educativos de más éxito a nivel internacional comparten la implementación de actuaciones que transforman el entorno social y cultural. Los datos presentados provienen de seis estudios de casos de centros educativos de éxito realizados en cinco países europeos. Los resultados indican que esas actuaciones fomentan el aprendizaje instrumental y, consecuentemente, un desarrollo cognitivo. En todas esas actuaciones es central una didáctica que se dirige a llevar a todas las y los estudiantes a niveles de conocimiento superior.

Socio-cultural factors in the development of anorexia nervosa.  

Science.gov (United States)

A population of professional dance (N = 183) and modelling (N = 56) students, who by career choice must focus increased attention and control over their body shapes, was studied. Height and weight data were obtained on all subjects. In addition, a questionnaire that is useful in assessing the symptoms of anorexia nervosa, the Eating Attitudes Test (EAT), was administered. Results of these tests were compared with those of normal female university students (N = 59), patients with anorexia nervosa (N = 68), and music students (N = 35). Anorexia nervosa and excessive dieting concerns were overrepresented in the dance and modelling students. Twelve cases (6.5%) of primary anorexia nervosa were detected in the dance group. All but one case developed the disorder while studying dance. Within the dance group those from the most competitive environments had the greatest frequency of anorexia nervosa. These data suggest that both pressures to be slim and achievement expectations are risk factors in the development of anorexia nervosa. The influence of socio-cultural determinants are discussed within the context of anorexia nervosa as a multidetermined disorder. PMID:7208724

Exploring complex sociocultural situations through soft operational research  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English 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 nor [...] mal 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.

Sociocultural patterning of neural activity during self-reflection.  

Science.gov (United States)

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 magnetic resonance imaging, 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.

Workplace learning in veterinary education: a sociocultural perspective.  

Science.gov (United States)

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.

Transformações socioculturais da alimentação hospitalar Sociocultural transformations in hospital food  

Directory of Open Access Journals (Sweden)

Full Text Available O artigo busca no passado os elementos constituintes da cultura alimentar hospitalar, com o objetivo de encontrar as raízes históricas da alimentação em instituições hospitalares. Pressupõe-se que a dieta não seja apenas resultante de procedimentos tecnocientíficos, mas também historicamente construída, criada e recriada perante aspectos econômicos e socioculturais. Realizou-se um mapeamento inicial em arquivos universitários, municipais e hospitalares de Campinas (SP, além de entrevistas com trabalhadores dos serviços de alimentação de três instituições hospitalares. Conclui-se que a valorização de ações e intervenções associadas à tecnologia, em detrimento daquelas identificadas com o universo doméstico, pode ter contribuído para certa negligência dos hospitais com a alimentação, considerada uma área de pouca importância.The article seeks to identify the historical roots of food culture in hospital settings. It assumes that diet is not merely the result of technical and scientific concerns but is also historically constructed, created, and recreated in response to economic and sociocultural elements. The study conducted a preliminary survey of university, municipal, and hospital archives in Campinas, São Paulo, and included interviews with food service workers at three hospital institutions. Our conclusion is that more value has been placed on initiatives and actions related to technology than on initiatives identified with the domestic world; this may have contributed to a certain tendency for hospitals to neglect the issue of food, deemed of minor importance.

Are there different sociocultural influences on body image and body change strategies for overweight adolescent boys and girls?  

Science.gov (United States)

This study examined how sociocultural messages differ for overweight and normal weight adolescents and how these messages predict body image and body change strategies. In total, 590 adolescents participated in the study. Overweight adolescents experienced greater body dissatisfaction, engaged in more strategies to lose weight, and experienced greater sociocultural messages to lose weight. Body dissatisfaction and sociocultural pressures predicted weight loss among overweight boys. Body image importance, and sociocultural pressures predicted increasing muscle bulk for normal and overweight boys. Weight loss for overweight girls was predicted by sociocultural pressures. Sociocultural pressures also predicted muscle increase for overweight and normal weight girls. Implications for intervention and prevention programs for overweight adolescent boys and girls are discussed. PMID:20434062

Virtual reality exposure therapy.  

Science.gov (United States)

It has been proposed that virtual reality (VR) exposure may be an alternative to standard in vivo exposure. Virtual reality integrates real-time computer graphics, body tracking devices, visual displays, and other sensory input devices to immerse a participant in a computer-generated virtual environment. Virtual reality exposure is potentially an efficient and cost-effective treatment of anxiety disorders. VR exposure therapy reduced the fear of heights in the first controlled study of virtual reality in treatment of a psychiatric disorder. A case study supported the efficacy of VR exposure therapy for the fear of flying. The potential for virtual reality exposure treatment for these and other disorders is explored, and therapeutic issues surrounding the delivery of VR exposure are discussed. PMID:9185067

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.

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.

High availability using virtualization  

International Nuclear Information System (INIS)

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 the running virtual machines to be distributed over a small number of servers, by exploiting the features of the virtualization layer: start, stop and move virtual machines between physical hosts. The 3RC system is based on a finite state machine, 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 virtual hosts. The whole Grid data center SNS-PISA is running at the moment in virtual environment under the high availability system.

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

Approach to assessing local socio-cultural impacts using projections of population growth and composition  

Energy Technology Data Exchange (ETDEWEB)

All assessment of future domestic development projects assumes that the problems to be examined have been properly identified and defined before the application of a projection technique. An attempt is made to codify socio-cultural problems mentioned in literature and clarify how existing demographic projection techniques can be applied to assessing the problems. The relationship between changes in local population size and composition induced by in-migration and the potential for socio-cultural incompatibilities is described heuristically. For simplification, the problems expected to emerge from differences in demographic composition are classified into three categories: (1) service needs, such as those for housing, recreation, and education; (2) types of social organizations related to capacities for, or constraints on, reaping the benefits of rapid economic development and social changes (e.g., employment and income); and (3) attitudes, values, and cultural perspectives. These areas of concern are very broad, and quantitative projections of population size and composition are more easily related to the first than to the third. Although demographic projection provides a valuable tool for estimating future social change, the knowledge about cause and effect is not sufficient to support the quantification of socio-cultural impact. Therefore, the projections are used only as relative indicators and the assessments of socio-cultural impact based on them are qualitative only. Therefore, identification and assessment of socio-cultural impacts are a means of developing plans to overcome the expected problems.

Generalized Contact Structures  

CERN Document Server

We study integrability of generalized almost contact structures, and find conditions under which the main associated maximal isotropic vector bundles form Lie bialgebroids. These conditions differentiate the concept of generalized contact structures from a counterpart of generalized complex structures on odd-dimensional manifolds. We name the latter strong generalized contact structures. Using a Boothby-Wang construction bridging symplectic structures and contact structures, we find examples to demonstrate that, within the category of generalized contact structures, classical contact structures have non-trivial deformations. Using deformation theory of Lie bialgebroids, we construct new families of strong generalized contact structures on the three-dimensional Heisenberg group and its co-compact quotients.

In this case, the virtual worlds are nested within each other, which put a severe restriction on the possible geometry of space-time. Discussed the draft geometry virtual worlds consistently displayed from one world to another. It is shown that in this case, the metric should be universal, depending only on the fundamental constants.

Socio-Cultural Context of Drug Use with Reflections to Cannabis Use in Croatia  

Directory of Open Access Journals (Sweden)

Full Text Available Socio-cultural context of drug use is reflected as the constitutive part of interpretation of its effects and corresponding meanings, both at macro and micro-societal level of sociological analysis. In the first part of the article some more influential social-theoretical approaches to drug use are considered. Most of them consider drug use in terms of sociology of subculture and deviance. In second part, Croatian socio-cultural context is analysed, with reflections on questioning key terms that are addressed in the first part of the article. The concluding part indicates the ability for critical reflection of part of theories with regard to specificities of Croatian socio-cultural context. Furthermore, it is indicated that is necessary to overcome existing focus on the war, transition and after-war period as still dominant interpretative model in actual Croatian social research on drug use.

Virtual Organizations: Beyond Network Organization  

Directory of Open Access Journals (Sweden)

Full Text Available One of the most used buzz-words in (e-business literature of the last decade is virtual organization. The term "virtual" can be identified in all sorts of combinations regarding the business world. From virtual products to virtual processes or virtual teams, everything that is “touched” by the computer’s processing power instantly becomes virtual. Moreover, most of the literature treats virtual and network organizations as being synonyms. This paper aims to draw a much more distinctive line between the two concepts. Providing a more coherent description of what virtual organization might be is also one of our intentions.

'Mobile men with money': the socio-cultural and politico-economic context of 'high-risk' behaviour among wealthy businessmen and government officials in urban China.  

Science.gov (United States)

China's transition from an injection drug-driven HIV epidemic to one primarily transmitted through sexual contact has triggered concern over the potential for HIV to move into the non-drug-injecting population. Much discussion has focused on the migrant men of China's vast 'floating population' who are considered a high-risk group. As a result, many men who frequently engage in high-risk behaviour but are not included in this especially vulnerable group are evading HIV prevention messages. This paper highlights the socio-cultural and politico-economic factors that motivate many of China's wealthy businessmen and government officials, sometimes referred to as 'mobile men with money', to engage in such behaviour. Examination of the activities related to the work of these men reveals a situation where the confluence of a market-oriented economy operating within a socialist-style political system under the influence of traditional networking practices has engendered a unique mode of patron-clientelism that brings them together over shared social rituals including feasting, drinking and female-centered entertainment that is often coupled with sexual services. As a result, consideration of the socio-cultural factors influencing these men's sexual practices is important for responding to the newly emerging stage of China's HIV epidemic. PMID:18975228

Contact laser vaporization of the prostate for benign prostatic hypertrophy  

Science.gov (United States)

The contact laser applications for the removal of the enlarged prostate are distinctly different than the majority of non-contact Nd:YAG lasers that rely on coagulation necrosis and delayed sloughing. Contact Nd:YAG laser allows cutting, coagulation and vaporization of tissue with minimal penetration beyond the contact surface. Using the contact laser prostatectomy technique, the contact laser probe directly touches and immediately vaporizes the prostatic tissue under the probe. The net result is the immediate removal of the obstructing tissue, in a manner similar to the standard electrosurgical TURP. This immediate removal of tissue offers the patient treated with the contact laser the potential for decreased catheter time and a more rapid resolution of symptoms. Our initial experience suggests that the contact technique may be better suited for the smaller prostate gland (i.e. less than 30 gm). The contact laser may also be used for a procedure termed the `laser assisted TURP': a standard electrosurgical TURP is performed and the contact laser is used for hemostasis. Several investigators have reported non-randomized results of the contact technique with good outcomes. A prospective randomized trial of the contact laser prostatectomy vrs the electrosurgical TURP is underway. The contact laser vaporization of the prostate holds great promise for the treatment of symptomatic benign prostatic hypertrophy: it is virtually bloodless and allows immediate visualization of the TUR defect.

Se, por um lado, usufruímos os benefícios das infinitas possibilidades de acesso e contato com outros mundos, por outro, nos deparamos com nossos novos comportamentos frente a estes o [...] utros mundos. Para ilustrar estas idéias, apresentamos um caso clínico no qual a paciente, uma jovem senhora de vinte e sete anos, casada há oito anos, tem vivido há um ano uma "relação virtual", pela internet. Este processo tem absorvido-a completamente. Ela sente-se muito distante de seu marido desde que isolou-se em seu mundo paralelo, no qual apresenta uma nova identidade em todos os níveis. Esta nova identidade é inteiramente oposta à de sua vida real. No entanto, a impossibilidade de sentir-se realizada, seja em sua vida cotidiana, seja em seu universo paralelo, desencadeou-lhe um grave processo depressivo. Este exemplo clínico levou-nos a discutir os seguintes aspectos: (1) as experiências virtuais pela internet e os universos paralelos mencionados por Hugh Everett, um físico norte - americano; (2) a questão da ética feminina; (3) as manifestações mobilizadas no grupo pela paciente.

In order to ilIustrate that idea, we have a clínica I report in which the patient, a young lady, twenty seven years oki, married for eight years, has been living for about one year a "virtual relationship", by internet. This process has been absorbing her completely. She feels very far trom her husband, since she is isolated in her parallel world, in which she has a new identity related to all levels. That new identity is entirely the opposite from her real life. The impossibility to feel accomplished either in her everyday lífe or in her virtual parallel universe broke out a severe pracess of depression. That clínic example leaded us to discuss the following aspects: (1) virtual experiences by internet and the parallel universes that was mentioned by Hugh Everett, a North American physicist; (2) the question of female ethics; (3) the group experiences that was mobilized by that patient.

Feedback on the Feedback: Sociocultural Interpretation of Saudi ESL Learners’ Opinions about Writing Feedback  

Directory of Open Access Journals (Sweden)

Full Text Available This qualitative study employed informal conversational interviews and semi-structured individual interviews to capture the Saudi students’ opinions about the feedback they receive, and about their perceptions on what constitutes helpful feedback. Sociocultural theory was used as the framework of this study. The findings suggest that the Saudi students do not think highly of the feedback, and that the feedback they desire is markedly different from what they receive. The students mentioned several impediments to feedback. From a sociocultural perspective, the feedback practices do not adhere to the best practices of the theory, resulting in major hindrances to the students’ learning/writing development.

Els codis socioculturals de la 'viuda desheretada' a "Pilar Prim" de Narcís Oller i a "Middlemarch" de George Eliot [The socio-cultural codes of the 'disinherited widow' in "Pilar Prim" by Narcís Oller and in "Middlemarch" by George Eliot  

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.

Desenvolvimento humano e cultura: integração entre filogênese, ontogênese e contexto sociocultural / Human development and culture: integration among phylogeny, ontogeny and sociocultural context  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese O presente artigo tem como objetivo principal apresentar reflexão teórica sobre a integração entre aspectos da história filogenética do ser humano e a história de desenvolvimento ontogenético, considerando o contexto sociocultural onde o indivíduo está inserido. Pressupostos da Psicologia do Desenvo [...] lvimento Evolucionista, da Psicologia Transcultural e da Psicologia da Cultura são utilizados como referenciais teóricos. Conceitos como epigênese são apresentados para indicar a relação entre genética e fatores ambientais. Diferentes conceitos de cultura também são expostos e discutidos criticamente. Por fim, relações entre modelos culturais de independência e interdependência com as trajetórias de desenvolvimento são apresentadas e discutidas. Através da análise crítica apresentada, conclui-se que o estudo do desenvolvimento (em suas dimensões em termos de filogênese e ontogênese) mediado pelo contexto sociocultural é consistente e representa um modelo promissor para gerar programas de pesquisas inovadores e originais. Abstract in english The present study aimed to present a theoretical reflection on the integration of aspects of the phylogenetic history of human beings and history of ontogenetic development, considering the socio-cultural context where the individual is inserted. Assumptions of Evolutionary Psychology, Cross-Cultura [...] l Psychology and the Psychology of Culture are used as theoretical background. Concepts such as epigenesis are presented to indicate the relationship between genetics and environmental factors. Different concepts of culture are shown and discussed critically. Finally, relations between cultural models of independence and interdependence with the trajectories of development are presented and discussed. Through the critical analysis presented, it is concluded that the study of development (in its dimensions in terms of phylogeny and ontogeny) mediated by the socio-cultural context is consistent and represents a promising model to generate innovative and original research programs.

Individual classroom experiences: a sociocultural comparison for understanding efl classroom language learning Individual classroom experiences: a sociocultural comparison for understanding efl classroom language learning  

Directory of Open Access Journals (Sweden)

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.

High availability using virtualization  

CERN Document Server

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.

Science Nation: Virtual Self  

Science.gov (United States)

An avatar is a movable image that people design to represent themselves in virtual reality environments or in cyberspace. Avatars are usually for fun and games but could avatars actually change us? Jeremy Bailenson thinks so. With support from the National Science Foundation (NSF), he created the Virtual Human Interaction Lab (VHIL) at Stanford University to study, among other things, the power avatars exert on their real world masters. Sometimes, avatars are designed to be ideal versions of their creators, and there's now evidence that the virtual reality persona begins to influence the real life persona.

Incorporation of Socio-Cultural Values in Damage Assessment Valuations of Contaminated Lands in the Niger Delta  

Directory of Open Access Journals (Sweden)

Full Text Available Damages on contaminated land have been mostly assessed for developments subsisting on the land, neglecting the goods and services derived from the land which possess only socio-cultural values. This paper aims to ascertain the importance of socio-cultural values in the total economic value of contaminated land, drawing from the experience of a coastal community oil spillage in the Niger Delta. The paper examines what constitutes a valuable interest on contaminated land and how socio-cultural factors are valued in the damage assessment process. After reviewing the literature and decided cases, a questionnaire survey was conducted and a sample valuation report was analysed. It is concluded that there exists a socio-cultural interest on contaminated land which professional valuers do not reflect in damage assessment claims. It is recommended that any comprehensive damage assessment requires the incorporation of socio-cultural values in the valuations.

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 interferometer (quantum interference between two parallel contacts) displays a mid connector and contacts of the same size, or contacts at which the middle one is twice the size as the other two, or a double connector and three contacts by which the middle contact carries twice the current as the other two. Also there can be provided interferometers with three and four contacts as well as with symmetrical double current connectors and the same largest Josephson current through all contacts. Because all contacts display the same phase state in the voltage free switching state, the amplification property can be increased and current dissipation can be decreased in a way that logic circuits with high integration degree and high switching velocities can be designed.

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.

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.

SOCIO-CULTURAL AND MEDICAL INDICATORS OF THE SCHOOLCHILDREN'S QUALITY OF LIFE  

Directory of Open Access Journals (Sweden)

Full Text Available An estimate of life quality is based upon medical, psychological and social indicators. It increasingly engages the attention of doctors of medicine, sociologists and psychologists.The aim of this research is to headlight some more relevant socio-cultural parametres in order to determine the quality of life of schoolchildren, that is, to determine whether the crisis in which our society has found itself has produced such socio-cultural conditions that could have induced changes in the children's quality of life and, if they have, to what extent the crisis has been reflected upon their health. The research has comprised 398 schoolchildren and their parents, three elementary schools from Nish and one in Sokobanja.The research of the socio-cultural and medical indicators of their quality of life has shown that the parent's education and ther material position have had an important influence upon the children's life quality.Since there has been no significant presence of any disease recorded in the observed children's sample, it can be concluded that the socio-cultural features have affected the children's life but they have not any significant impact upon their health.

Virtual Heritage Network  

Science.gov (United States)

"The Virtual Heritage Network [VHN], is a new international organisation designed to promote the utilisation of technology for the education, interpretation, conservation and preservation of Natural, Cultural and World Heritage." The heart of VHN is a searchable library that consists of papers, articles, and reports "discussing applications, tools, games, [and] financial and legal aspects" of virtual heritage. Submissions are self-selected and given online reviews by site users, but everything we saw here was professional and, in most cases, had been published elsewhere in academic or news media forums. The site also lets users keep up to date with current developments in the virtual heritage industry via a newsletter, and for members (registration free), offers an email digest of recent submissions to the site, an electronic mailing list, and a forthcoming message board. For the uninitiated, the site has reprinted an article from the November edition of UNESCO's World Heritage Magazine explaining the concept of Virtual Heritage (available from the What is Virtual Heritage? link on the front page). The VHN was established this month by the International Society on Virtual Systems and MultiMedia (VSMM Society) with the support of the UNESCO World Heritage Centre.

The Virtual Observatory: I  

Science.gov (United States)

The concept of the Virtual Observatory arose more-or-less simultaneously in the United States and Europe circa 2000. Ten pages of Astronomy and Astrophysics in the New Millennium: Panel Reports (National Academy Press, Washington, 2001), that is, the detailed recommendations of the Panel on Theory, Computation, and Data Exploration of the 2000 Decadal Survey in Astronomy, are dedicated to describing the motivation for, scientific value of, and major components required in implementing the National Virtual Observatory. European initiatives included the Astrophysical Virtual Observatory at the European Southern Observatory, the AstroGrid project in the United Kingdom, and the Euro-VO (sponsored by the European Union). Organizational/conceptual meetings were held in the US at the California Institute of Technology (Virtual Observatories of the Future, June 13-16, 2000) and at ESO Headquarters in Garching, Germany (Mining the Sky, July 31-August 4, 2000; Toward an International Virtual Observatory, June 10-14, 2002). The nascent US, UK, and European VO projects formed the International Virtual Observatory Alliance (IVOA) at the June 2002 meeting in Garching, with yours truly as the first chair. The IVOA has grown to a membership of twenty-one national projects and programs on six continents, and has developed a broad suite of data access protocols and standards that have been widely implemented. Astronomers can now discover, access, and compare data from hundreds of telescopes and facilities, hosted at hundreds of organizations worldwide, stored in thousands of databases, all with a single query.

Broadening the examination of sociocultural constructs relevant to African-American colorectal cancer screening.  

Science.gov (United States)

The importance of sociocultural constructs as influences on cancer attitudes and screening has been established in the literature. This paper reports on the efforts to explore alternatives to sociocultural constructs previously associated with African-American cancer screening, but with low acceptance among community members or incomplete measurement (empowerment and collectivism) and develop a measure for a recently identified construct of interest (privacy). We report preliminary psychometric data on these sociocultural scales and their associations with cancer attitudes. African-Americans (N?=?1021), 50-75?years of age participated in this study. Participants were identified via a listed sample and completed a telephone survey administered via call center. Sociocultural attitudes were assessed using items identified through computerized database searches, reviewed by advisory panels, edited and tested using cognitive response strategies. Cancer screening pros and cons, cancer worry, perceived cancer risk, colorectal cancer (CRC) screening subjective norms, and perceived self-efficacy for colorectal cancer screening (CRCS) were also assessed. Confirmatory factor analyses and multivariate analyses were conducted to provide support for the validity of the constructs and to understand the associations among the selected sociocultural constructs (empowerment, collectivism, and privacy) and cancer beliefs and attitudes (CRC perceived benefits and barriers, perceived risks, subjective norms, and perceived behavioral control/self-efficacy). Consistent with the literature, the factor analytic model (RMSEA for the model was .062; 90% CI: .060-.065) provided support for the empowerment, collectivism, and privacy constructs. The modified collectivism and privacy scales had acceptable reliability. The privacy scale demonstrated the strongest associations with measures of cancer beliefs and attitudes. The implication of the findings and need for further scale development activities is discussed. PMID:24628025

Contact lens in keratoconus.  

Science.gov (United States)

Contact lenses are required for the visual improvement in patients with keratoconus. Various contact lens options, such as rigid gas permeable (RGP) lenses, soft and soft toric lenses, piggy back contact lenses (PBCL), hybrid lenses and scleral lenses are availble. This article discusses about selection of a lens depending on the type of keratoconus and the fitting philosophies of various contact lenses including the starting trial lens. A Medline search was carried out for articles in the English language with the keywords keratoconus and various contact lenses such as Rose k lens, RGP lens, hybrid lens, scleral lens and PBCL.

Modeling Thermal Contact Resistance  

Science.gov (United States)

One difficulty in using cryocoolers is making good thermal contact between the cooler and the instrument being cooled. The connection is often made through a bolted joint. The temperature drop associated with this joint has been the subject of many experimental and theoretical studies. The low temperature behavior of dry joints have shown some anomalous dependence on the surface condition of the mating parts. There is also some doubts on how well one can extrapolate from the test samples to predicting the performance of a real system. Both finite element and analytic models of a simple contact system have been developed. The model assumes (a) the contact is dry (contact limited to a small portion of the total available area and the spaces in-between the actual contact patches are perfect insulators), (b) contacts are clean (conductivity of the actual contact is the same as the bulk), (c) small temperature gradients (the bulk conductance may be assumed to be temperature independent), (d) the absolute temperature is low (thermal radiation effects are ignored), and (e) the dimensions of the nominal contact area are small compared to the thickness of the bulk material (the contact effects are localized near the contact). The models show that in the limit of actual contact area much less than the nominal area (a much less than A), that the excess temperature drop due to a single point of contact scales as a(exp -1/2). This disturbance only extends a distance approx. A(exp 1/2) into the bulk material. A group of identical contacts will result in an excess temperature drop that scales as n(exp -1/2), where n is the number of contacts and n dot a is constant. This implies that flat rough surfaces will have a lower excess temperature drop than flat polished surfaces.

Virtual data in CMS production  

Energy Technology Data Exchange (ETDEWEB)

Initial applications of the GriPhyN Chimera Virtual Data System have been performed within the context of CMS Production of Monte Carlo Simulated Data. The GriPhyN Chimera system consists of four primary components: (1) a Virtual Data Language, which is used to describe virtual data products, (2) a Virtual Data Catalog, which is used to store virtual data entries, (3) an Abstract Planner, which resolves all dependencies of a particular virtual data product and forms a location and existence independent plan, (4) a Concrete Planner, which maps an abstract, logical plan onto concrete, physical grid resources accounting for staging in/out files and publishing results to a replica location service. A CMS Workflow Planner, MCRunJob, is used to generate virtual data products using the Virtual Data Language. Subsequently, a prototype workflow manager, known as WorkRunner, is used to schedule the instantiation of virtual data products across a grid.

Real-time control of an interactive impulsive virtual prosthesis.  

Science.gov (United States)

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 nonamputee 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. PMID:23996579

Varieties of virtualization  

Science.gov (United States)

Natural environments have a content, i.e., the objects in them; a geometry, i.e., a pattern of rules for positioning and displacing the objects; and a dynamics, i.e., a system of rules describing the effects of forces acting on the objects. Human interaction with most common natural environments has been optimized by centuries of evolution. Virtual environments created through the human-computer interface similarly have a content, geometry, and dynamics, but the arbitrary character of the computer simulation creating them does not insure that human interaction with these virtual environments will be natural. The interaction, indeed, could be supernatural but it also could be impossible. An important determinant of the comprehensibility of a virtual environment is the correspondence between the environmental frames of reference and those associated with the control of environmental objects. The effects of rotation and displacement of control frames of reference with respect to corresponding environmental references differ depending upon whether perceptual judgement or manual tracking performance is measured. The perceptual effects of frame of reference displacement may be analyzed in terms of distortions in the process of virtualizing the synthetic environment space. The effects of frame of reference displacement and rotation have been studied by asking subjects to estimate exocentric direction in a virtual space.

La adecuación sociolingüística y sociocultural en alumnos búlgaros del español como lengua extranjera / Sociolinguistic and sociocultural adequacy of Bulgarian students of Spanish as a foreign language  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish Dedicamos este estudio a la adecuación como un componente de la competencia sociolingüística, sociocultural e intercultural en español como lengua extranjera. Para ello, realizamos un tipo de investigación estadística cuantitativa con el programa SPSS 17 (Statistical Product and Service Solutions), [...] en la que aplicamos el análisis descriptivo y el inferencial. El instrumento del estudio es un cuestionario y los participantes son 59 alumnos de origen búlgaro que estudian el español como lengua extranjera en situación de no inmersión. Los niveles de español de los participantes son B1, C1 y C2. 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 study 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.

CORTESÍA SOCIOCULTURAL EN LAS SOCIEDADES MEDELLINENSE Y JAPONESA: UNA INTRODUCCIÓN / SOCIO-CULTURAL POLITENESS IN MEDELLÍN AND JAPANESE SOCIETIES: AN INTRODUCTION  

Scientific Electronic Library Online (English)

Full Text Available SciELO Colombia | Language: Spanish Abstract in spanish En este artículo se presenta un análisis intercultural de la sociedad medellinense y la japonesa, teniendo en cuenta la variabilidad de la cortesía sociocultural de una cultura a otra, con el fin de que sirva de apoyo para los aprendices de una segunda lengua o lengua extranjera. Como punto de parti [...] da, se acude a nociones como pragmática en interlengua, transferencia pragmática y el modelo de la cortesía verbal de Brown y Levinson (1987), junto con las nociones de face flattering acts (FFAs), cortesía mitigadora, cortesía valorizante, imagen de autonomía y afiliación, y los contenidos concretos de estas últimas dos categorías. El corpus del estudio se basa en algunos episodios recogidos en Medellín y en Japón. El análisis se centra en algunos actos de habla, especialmente en las relaciones interpersonales no solidarias. En este tipo de relaciones, en la sociedad medellinense se prefiere salvar la imagen positiva, y en la japonesa, la imagen negativa. Es importante señalar explícitamente la variabilidad de la cortesía sociocultural de una cultura a otra, no sólo a los aprendices avanzados de una segunda lengua o lengua extranjera, sino también a los principiantes. Abstract in english This paper presents an intercultural analysis between the Medellin and the Japanese society, taking into account the variability of the socio-cultural politeness from one culture to another, to serve as support for second language learners or foreign language. As a starting point, there are notions [...] of interlanguage pragmatics, pragmatic transfer and the model of politeness of Brown and Levinson (1987) with its alternatives. The corpus of the study is based on some episodes collected in Medellin and in Japan. The analysis focuses on some speech acts, especially in non-solidarity interpersonal relationships. In such relationships, in Medellin society is preferred to save the positive face and in the Japanese, the negative face. It is important to teach the variability of the socio-cultural politeness from one culture to another explicitly not only to advanced learners of a second or foreign language, but beginners.

Contact and symplectic topology  

CERN Document Server

Symplectic and contact geometry naturally emerged from the mathematical description of classical physics. The discovery of new rigidity phenomena and properties satisfied by these geometric structures launched a new research field worldwide. The intense activity of many European research groups in this field is reflected by the ESF Research Networking Programme "Contact And Symplectic Topology" (CAST). The lectures of the Summer School in Nantes (June 2011) and of the CAST Summer School in Budapest (July 2012) provide a nice panorama of many aspects of the present status of contact and symplectic topology. The notes of the minicourses offer a gentle introduction to topics which have developed in an amazing speed in the recent past. These topics include 3-dimensional and higher dimensional contact topology, Fukaya categories, asymptotically holomorphic methods in contact topology, bordered Floer homology, embedded contact homology, and flexibility results for Stein manifolds.

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.

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.

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.

Virtual reality welder training  

Science.gov (United States)

This document describes the Virtual Reality Simulated MIG Lab (sMIG), a system for Virtual Reality welder training. It is designed to reproduce the experience of metal inert gas (MIG) welding faithfully enough to be used as a teaching tool for beginning welding students. To make the experience as realistic as possible it employs physically accurate and tracked input devices, a real-time welding simulation, real-time sound generation and a 3D display for output. Thanks to being a fully digital system it can go beyond providing just a realistic welding experience by giving interactive and immediate feedback to the student to avoid learning wrong movements from day 1.

Virtual power plant auctions  

Energy Technology Data Exchange (ETDEWEB)

Since their advent in 2001, virtual power plant (VPP) auctions have been implemented widely. In this paper, we describe the simultaneous ascending-clock auction format that has been used for virtually all VPP auctions to date, elaborating on other design choices that most VPP auctions have had in common as well as discussing a few aspects that have varied significantly among VPP auctions. We then evaluate the various objectives of regulators in requiring VPP auctions, concluding that the auctions have been effective devices for facilitating new entry into electricity markets and for developing wholesale power markets.

Physical appearance and cosmetic medical treatments: physiological and socio-cultural influences.  

Science.gov (United States)

This paper reviews the physiological and socio-cultural literatures on the role of physical appearance in daily life and its potential influence on the decision to pursue cosmetic medical treatments. The role of physical appearance in evolutionary theory is discussed. Physiological theories of beauty, drawn from both animal and human research, are reviewed. Socio-cultural influences on physical appearance are considered by tracing changes in ideals of beauty over the last century. The paper then reviews the literature concerning the relationship between a person's physical appearance and how they are treated throughout their lives. The growing awareness of this 'beauty bias' may influence the decision to alter one's physical appearance through cosmetic procedures. PMID:17156046

Adolescents' Experiences of Discrimination and Parent-Adolescent Relationship Quality: The Moderating Roles of Sociocultural Processes.  

Science.gov (United States)

Grounded in a cultural-ecological perspective, the goals of this study were to examine the implications of young adolescents' experiences of racial discrimination for the quality of relationships with mothers and fathers and to test whether sociocultural processes, such as youth ethnic identity and parents' racial socialization strategies, moderated these linkages. Participants were older and younger adolescents in 176 two-parent African American families who completed questionnaires about their discrimination experiences, ethnic identities, and warmth and conflict in their relationships with parents. Mothers and fathers reported on cultural socialization and preparation for bias practices. Consistent with an emotional spillover hypothesis, discrimination was linked to poorer relationship quality with both mothers and fathers. Youth ethnic identity and mothers' racial socialization moderated discrimination-relationship linkages. Findings were consistent with prior research on discrimination and highlight the protective nature of some sociocultural processes for family relationships. PMID:22942511

The trajectory of coparenting satisfaction in African American families: the impact of sociocultural stressors and supports.  

Science.gov (United States)

Based in family systems and ecological perspectives, this study expands the scope of coparenting research by: (a) charting the trajectory of coparenting satisfaction for mothers and fathers in two-parent African American families during their offspring's adolescence, and (b) examining the role of sociocultural stressors and supports for coparenting satisfaction. Participants were 192 African American mothers and fathers who reported on their coparenting satisfaction and both economic and cultural stressors (economic strain and racial discrimination), and supports (socioeconomic resources and religiosity). Longitudinal growth curves revealed declines in coparenting satisfaction for fathers but not mothers over the course of offspring's adolescence. Findings were generally consistent with hypotheses that stressors were negatively, and supports, positively, related to average levels of coparenting satisfaction. Findings for racial discrimination and income differed by parent and highlighted gender dynamics within couple relationships. We discuss implications for understanding of normative family processes in African American families as these unfold within both family and broader sociocultural contexts. PMID:23066677

The Role of Language-Game in Sociocultural Adaptation: Russian Students in France  

Directory of Open Access Journals (Sweden)

Full Text Available Higher educational institutions throughout the world are involved in communication with each other, exchanging instructional ideas and practices, as well as exchanging students through a number of international mobility programs. This paper examines sociocultural adaptation of international students with special attention to the dimensions of adaptation viewed from the perspective of language-game. For this purpose, 34 Russian students who study in French universities and higher schools (“grandes écoles” as exchange students were interviewed in Paris (France and Novosibirsk (Russia. The research shows that language-game is used in different dimensions of adaptation related to educational system, sociocultural context, mentality, and sociopolitical life. In order to overcome problems in adaptation and establish successful interaction, students use language-game to adjust to the unfamiliar social, cultural, and educational contexts.

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.

Sociocultural influences on body dissatisfaction and body change behaviors among Malaysian adolescents.  

Science.gov (United States)

Little research on body dissatisfaction and body change behaviors, and the sociocultural influences on them, has been undertaken in non-Western contexts. The current study investigated these variables and the relationships between them among a sample of 529 Malaysian high school students (103 Malays, 344 Chinese and 82 Indians), who completed a set of measures in classroom settings. Chinese girls were more dissatisfied with their bodies than Chinese boys, but no gender difference was found for Malay and Indian participants. Girls were more likely to engage in behaviors to lose weight, and boys were more likely to engage in behaviors to increase muscle. The influence of sociocultural factors on body dissatisfaction and body change behaviors was limited and varied across both sex and ethnicity. Findings are discussed in relation to Western research, and it is concluded that cultural nuances need to be considered when investigating these phenomena. PMID:19195942

Directory of Open Access Journals (Sweden)

Full Text Available Este artículo trata el impacto de las ideas de Lev S. Vygotski en la psicología cognosciti va contemporánea. En el mismo, argumento que su conceptualización del origen historicocultural de la mente y su énfasis en el método genético para estudiar la actividad mental fueron seminales en el desarrollo del enfoque sociocultural que al presente cobra fuerza en la investigación cognoscitiva. Planteo que esta fuerza obedece a las herramientas conceptuales y metodológicas que ofrece dicho enfoque para abordar algunos de los problemas que ha enfrentado la investigación cognoscitiva en el curso de su desarrollo. Examino este desarrollo a partir de la investigación realizada desde las perspectivas psicométrica, piagetiana, sociocultural y de procesamiento de información. Concluyo que los resultados de la investigación desde estas diferentes perspectivas ha llevado revisiones y reconceptualizaciones que implican un creciente reconocimiento a la vigencia de las ideas de Vygotski respecto a la mediación de las herramientas culturales en los procesos cognoscitivos.

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.

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

Science.gov (United States)

Summary Abstract 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. PMID:24051701

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.

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 SciELO Mexico | Language: English 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.

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

Science.gov (United States)

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. PMID:24639734

A socio-anthropological theoretical framework of the so-called Grid-Group Cultural Theory provides a typological model for understanding and mapping of cultural biases (shared values and beliefs), corresponding social relations and strategic behaviours. The starting argument of this paper is that this model can be used to illuminate and investigate the socio-cultural differences in peacebuilding approaches as the four theoretical ideal-types of individualism, egalitarianism, hierarchy and fat...

Using a socio-cultural CLIL pedagogical model to develop subject matter CLIL Courses

Sociocultural theory suggests that knowledge is a cultural construct initially co-constructed on the social plane, before being internalised by learners. From this perspective the teacher in the subject classroom represents a cultural body of knowledge and is responsible both for the mediation of this knowledge to learners, as well as the apprenticeship of learners into a particular knowledge community. The primary tool in this approach is language. This approach therefore offers a potentiall...

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.

Virtual bronchoscopy; Virtuelle Bronchoskopie  

Energy Technology Data Exchange (ETDEWEB)

Flexible bronchoscopy represents a clinically well-established invasive diagnostic tool. Virtual bronchoscopies, calculated from thin-slice CT sections, allow astonishing immitations of reality although principal differences exist between both technologies: the Fact that colour representation is artificial and concommitant interventions are impossible limits the clinical use of virtual bronchoscopy. However, its value increases when calculations can be attained within minutes due to technological advancements, and when virtually any chest CT is suitable for further postprocessing. Indications, findings and the clinical role of virtual bronchoscopy are discussed. (orig.) [German] Die flexible Bronchoskopie ist heute im Spektrum klinisch-invasiver Untersuchungen fest etabliert. Virtuelle Bronchoskopien, berechnet aus CT-Daten mit duenner Schichtdicke, gestatten realitaetsnahe Imitationen, wenngleich prinzipielle Unterschiede zwischen den Techniken bestehen: die fehlende natuerliche Farbwidergabe und fehlende Moeglichkeit, Interventionen in gleicher Sitzung durchzufuehren, limitieren den klinischen Einsatz der virtuellen Bronchoskopie. Dennoch gewinnt die Methode an Bedeutung, zumal der Arbeitsaufwand durch verbesserte Rechnerleistung auf wenige Minuten reduziert werden kann und mit Hilfe von Mehrschicht-CT-Technologie jedes Thorax-CT zur Nachverarbeitung geeignet ist. Indikationen, Befunde und der klinische Stellenwert der virtuellen Bronchoskopie werden diskutiert. (orig.)

Socio-cultural and cognitive predictors of eating disorder symptoms in young girls.  

Science.gov (United States)

There is some evidence for a relationship between socio-cultural variables and the development of disordered eating or concerns. However, the role of individual cognition in adding to this relationship has not yet been investigated. The current study therefore had two main questions. Firstly, which of the socio-cultural factors investigated (parental, peers and the media) predict girls' eating disorder related symptoms? Secondly, do individuals' cognitions add to this prediction? Thirty-eight girls participated in the study. They completed the Eating Attitudes Test (EAT), Eating Disorder Belief Questionnaire (EDBQ), measures of parental, peer and media influence, and a measure of their awareness and internalisation of societal standards of attractiveness. The results indicated that several of the socio-cultural factors were related to girls' EAT score. The belief that being thinner would make boys like them more was the most significant predictor in the whole sample (and in younger girls). Individual cognitions added significantly to this prediction in the whole sample but not in the younger girls. For older girls, the importance of magazines as a source of information about beauty and ideals was the strongest predictor of EAT score, and their cognitions added significantly to this prediction. It is concluded that peer and media influences are important determinants of girls' eating disorder related symptoms. However, individual cognitions add to this relationship, particularly in older girls. The implications and limitations of the study are discussed. PMID:16682869

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.

[The socio-cultural and eating aspects of women experiencing risk pregnancies].  

Science.gov (United States)

To promote a healthy diet, the dietary guidance should consider socio-cultural factors as they influence both the food standards and preferences of each population. The aim of this study was to describe the socio-cultural contexts of pregnancy and feeding in the domestic arena, using a qualitative approach. In-depth interviews were conducted using the data saturation technique with six women experiencing high-risk pregnancy. The interviews were transcribed and analyzed in accordance with the Bardin method and the IT Atlas program. The following aspects were identified: uncertainty due to unplanned pregnancy and limited partner support; a few dietary changes to improve health; perception of bad and good feeding habits, although it did not comply with the characteristics of a good diet; omission of fruit and vegetable group from dinner. The people in charge of preparing and serving food were not always the pregnant woman; food products perceived as being harmful were consumed and beneficial products were rarely consumed. This highlighted the need to train professionals to consider the socio-cultural context when providing dietary guidance. PMID:24897207

Differences in sociocultural environment perceptions associated with gender in science classrooms  

Science.gov (United States)

An amount-of-learning outcome variable has been attributed to the environment in which teaching and learning are conducted. Studies carried out so far have, however, not focused on the sociocultural aspect of the classroom environment, which has been theorized to have potential influence on students' learning. The intent of this study was to examine the influence of five aspects of the sociocultural environment in science classes with particular reference to how these are perceived by boys and girls. The 30-item Socio-Cultural Environment Scale (SCES) developed by Jegede and Okebukola (1988) was used to collect data from 707 Nigerian secondary school students in Classes Four and Five (Grades 10 and 11, respectively). Authoritarianism, goal structure, African worldview, societal expectation, and sacredness of science were the five subscales studied. Sex differences were recorded in the societal expectation subscale. Most of the female subjects are of the opinion that society has a negative or low regard for their ability to do science and this has an effect on their motivation to undertake science-based careers. The reverse is true for boys. This perception is in agreement with the literature on sex differences in science education and highlights the social pressure that brings about subject preferences. The implications of these findings for science teaching and further research are highlighted.

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

Energy Technology Data Exchange (ETDEWEB)

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

DEFF Research Database (Denmark)

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.

Community group environment for people participation and empowerment: the socio-cultural perspective  

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english The study was conducted in Makhuduthamaga Municipal area in Sekhukhune District of Limpopo Province in South Africa. The study observed how socio-cultural factors impact on participation environment in community development groups particularly in rural sections of society. To generate insight on the [...] se dynamics, some sets of empirical data were collected from community groups and individuals. Qualitative and quantitative sets of data were collected through structured interview schedule from simple random samples of twelve interest groups and twenty-eight individuals, and a quota sample of two organisational linkage structures. Document review of the groups was also conducted. Qualitative sets of data were collected from a simple random sample of two groups through participant observation to establishing their group dynamics and cultural protocols. The study found that the majority of community groups consisted of elderly people. It also found that the majority of people join community groups to participate in social improvement and participation. From document reviewed, no statute was found to provide for socio-cultural protocols in the groups' activities. From the observation, the study found that there are some socio-cultural norms, practices and values that negatively impact on the participation and empowerment of people in community development groups.

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.

Historical development of the overhead line (contact line); Geschichtliche Entwicklung der Fahrleitung (Oberleitung)  

Energy Technology Data Exchange (ETDEWEB)

The types of overhead line in use with Deutsche Bahn AG cover virtually all the areas assigned to them. Some small improvements can still be obtained in types Re 160 and Re 200, for example in terms of equal elasticity of the hinged or pulley steady arm. Where gliding hangers are used with catenaries with double contact wires, unequal wear of the two contact wires on the standard gliding hanger, which virtually doubles the service life of the contact wires. With higher tensioning of the two contact wires and the messenger, the permissible maximum speed can be increased further, which means they can also be recommended for use in mainline tunnels. To minimise the major wear on the contact wire, service life can be lengthened several times over by taking appropriate measures on the contact strip. (orig.)

User and virtual organisation support in EGEE  

CERN Document Server

User and virtual organisation support in EGEE Providing adequate user support in a grid environment is a very challenging task due to the distributed nature of the grid. The variety of users and the variety of Virtual Organizations (VO) with a wide range of applications in use add further to the challenge. The people asking for support are of various kinds. They can be generic grid beginners, users belonging to a given Virtual Organization and dealing with a specific set of applications, site administrators operating grid services and local computing infrastructures, grid monitoring operators who check the status of the grid and need to contact the specific site to report problems; to this list can be added network specialists and others. Wherever a user is located and whatever the problem experienced is, a user expects from a support infrastructure a given set of services. A non-exhaustive list is the following: a) a single access point for support; b) a portal with a well structured sources of information a...

Numerical algorithms for contact problems in linear elastostatics  

International Nuclear Information System (INIS)

In this work contact problems in linear elasticity are analysed by means of Finite Elements and Mathematical Programming Techniques. The principle of virtual work leads in this case to a variational inequality which in turn is equivalent, for Hookean materials and infinitesimal strains, to the minimization of the total potential energy over the set of all admissible virtual displacements. The use of Gauss-Seidel algorithm with relaxation and projection and also Lemke's algorithm and Uzawa's algorithm for solving the minimization problem is discussed. Finally numerical examples are presented. (Author)

Three Southern high school biology teachers' perspectives on teaching evolution: Sociocultural influences  

Science.gov (United States)

Organizations in science and science education call for students to have a thorough understanding of the theory of evolution. Yet many high school biology teachers do not teach evolution and/or include creationism in their instruction (National Academy of Science, 1998). Historically, the controversy surrounding evolution has created tension for teachers. This case study explored the sociocultural influences related to teaching evolution in three Southern 10th-grade public high school biology classrooms. It also explored the socially and culturally embedded influences on teachers' instructional goals and personal perspectives toward evolution as well as modification of instruction when evolution is taught. Theoretically framed using symbolic interactionism and sociocultural theory, data were collected between October 2003 and April 2004 and included classroom observations two to three times per week, artifacts, and in-depth interviews of the participating teachers, their science department chairpersons, their students, and a Protestant minister. The classroom teachers were unaware of the focus of the study until after evolution was taught. The analysis used in this study was an inductive, interpretative approach that allowed exploration of the sociocultural influences that affect how teachers teach evolution. The sociocultural influences and the lived experiences of each teacher created a continuum for teaching evolution. One of the participating teachers who was heavily involved in the community and one of its fundamentalist churches elected to avoid teaching evolution. Another participating teacher at the same school integrated the theory of evolution in every unit. The third teacher who taught in another school elected to teach evolution in a superficial manner to avoid conflict. The data revealed that the participating teachers' sociocultural situatedness influenced their decisions and instruction on evolution. The influence of strong religious beliefs within the Southern culture was a theme that cut across all the teachers' decisions. In particular, religious beliefs made teaching human evolution difficult. Other recurring themes included the influence of the textbook and factors that served as escape routes for the teachers electing to avoid evolution. The escape routes included the pressure of time, the mixed messages from the state board of education, and the double-edged sword of teacher autonomy.

Topological contact dynamics II: topological automorphisms, contact homeomorphisms, and non-smooth contact dynamical systems  

CERN Document Server

This sequel to our previous paper [MS11b] continues the study of topological contact dynamics and applications to contact dynamics and topological dynamics. We provide further evidence that the topological automorphism groups of a contact structure and a contact form are the appropriate transformation groups of contact dynamical systems. The article includes an examination of the groups of time-one maps of topological contact and strictly contact isotopies, and the construction of a bi-invariant metric on the latter. Moreover, every topological contact or strictly contact dynamical system is arbitrarily close to a continuous contact or strictly contact dynamical system with the same end point. In particular, the above groups of time-one maps are independent of the choice of norm in the definition of the contact distance. On every contact manifold we construct topological contact dynamical systems with time-one maps that fail to be Lipschitz continuous, and smooth contact vector fields whose flows are topologi...

The wheel center is given by a straight line parallel to the foundation, passing through permanent center of rotation. So, the wheel rail contact force has no contribution originating from the wheel inertia in vertical direction. The change in the contact point forms no more a straight line in the time domain. This occur due to any irregularities in the wheel rail interface. Irregularity can occur either on rail or on the wheel

Diagnostic accuracy in virtual dermatopathology  

DEFF Research Database (Denmark)

Background Virtual microscopy is used for teaching medical students and residents and for in-training and certification examinations in the United States. However, no existing studies compare diagnostic accuracy using virtual slides and photomicrographs. The objective of this study was to compare diagnostic accuracy of dermatopathologists and pathologists using photomicrographs vs. digitized images, through a self-assessment examination, and to elucidate assessment of virtual dermatopathology. Methods Forty-five dermatopathologists and pathologists received a randomized combination of 15 virtual slides and photomicrographs with corresponding clinical photographs and information in a self-assessment examination format. Descriptive data analysis and comparison of groups were performed using a chi-square test. Results Diagnostic accuracy in dermatopathology using virtual dermatopathology or photomicrographs was similar: 0.70 vs. 0.73 respectively, p = 0.465. Order of administration of virtual dermatopathology and photomicrographs did not affect diagnostic accuracy. The vast majority (93%) of the participants felt the virtual slides were adequate for diagnosis and that virtual dermatopathology represented a useful tool for learning; 90% felt that virtual dermatopathology is useful tool for teaching dermatopathology. Conclusion No significant difference was observed in diagnostic accuracy using virtual dermatopathology compared to photomicrographs. Most participants felt virtual dermatopathology was adequate for diagnostic purposes and a useful tool for learning and teaching dermatopathology. Copyright © 2012 John Wiley & Sons A/S.

Art in virtual reality 2010  

Science.gov (United States)

For decades, virtual reality artwork has existed in a small but highly influential niche in the world of electronic and new media art. Since the early 1990's, virtual reality installations have come to define an extreme boundary point of both aesthetic experience and technological sophistication. Classic virtual reality artworks have an almost mythological stature - powerful, exotic, and often rarely exhibited. Today, art in virtual environments continues to evolve and mature, encompassing everything from fully immersive CAVE experiences to performance art in Second Life to the use of augmented and mixed reality in public space. Art in Virtual Reality 2010 is a public exhibition of new artwork that showcases the diverse ways that contemporary artists use virtual environments to explore new aesthetic ground and investigate the continually evolving relationship between our selves and our virtual worlds.

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 reality systems  

Science.gov (United States)

Virtual realities are a type of human-computer interface (HCI) and as such may be understood from a historical perspective. In the earliest era, the computer was a very simple, straightforward machine. Interaction was human manipulation of an inanimate object, little more than the provision of an explicit instruction set to be carried out without deviation. In short, control resided with the user. In the second era of HCI, some level of intelligence and control was imparted to the system to enable a dialogue with the user. Simple context sensitive help systems are early examples, while more sophisticated expert system designs typify this era. Control was shared more equally. In this, the third era of the HCI, the constructed system emulates a particular environment, constructed with rules and knowledge about 'reality'. Control is, in part, outside the realm of the human-computer dialogue. Virtual reality systems are discussed.

Virtual reality for microassembly  

Science.gov (United States)

The growing demand for advanced micro-devices that integrate various sensors and actuators, e.g. for biomedical applications, has created a strong need for assembly units that can meet high precision and manipulation requirements. However, developing a sophisticated machine that can fulfill these requirements solves only a part of the problem - having a skilled person that can program and operate the machine must also be addressed. The user interface should provide sufficient information to perform any assembly operation, however, it should also hide or abstract information that would distract the operator from the main task. Controlling the information flow from/to the user and to/from the machine is performed by representing the real environment in a virtual one. This additional layer of abstraction between the user and the machine is based on a standard virtual reality (VR) approach. This paper demonstrates the integration of such a VR system into an existing microassembly station.

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.

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.

Fragrance allergic contact dermatitis.  

Science.gov (United States)

Fragrances are a common cause of allergic contact dermatitis in Europe and in North America. They can affect individuals at any age and elicit a spectrum of reactions from contact urticaria to systemic contact dermatitis. Growing recognition of the widespread use of fragrances in modern society has fueled attempts to prevent sensitization through improved allergen identification, labeling, and consumer education. This review provides an overview and update on fragrance allergy. Part 1 discusses the epidemiology and evaluation of suspected fragrance allergy. Part 2 reviews screening methods, emerging fragrance allergens, and management of patients with fragrance contact allergy. This review concludes by examining recent legislation on fragrances and suggesting potential additions to screening series to help prevent and detect fragrance allergy. PMID:25207685

Contact alternatives to nickel.  

Science.gov (United States)

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. PMID:24030370

Occupational contact dermatitis.  

Science.gov (United States)

The dermatologist should be aware of the many facets of occupational skin diseases, which can be caused by physical, chemical, and biological insults. The most common manifestation of occupational skin diseases is contact dermatitis (both irritant and allergic). Three factors point out the importance of occupational skin diseases as diseases that have a public health impact: 1) occupational skin diseases are common; 2) they often have a poor prognosis; and 3) they result in a noteworthy economic impact for society and for an individual. They are also diseases amenable to public health interventions. Specific industries and exposures may put a worker at risk of occupational contact dermatitis. The accuracy of the diagnosis of occupational contact dermatitis is related to the skill level, experience, and knowledge of the medical professional who makes the diagnosis and confirms the relationship with a workplace exposure. Prevention of occupational contact dermatitis is important, and a variety of prevention strategies are available. PMID:15186373

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.

Science.gov (United States)

Virtual blood bank is the computer-controlled, electronically linked information management system that allows online ordering and real-time, remote delivery of blood for transfusion. It connects the site of testing to the point of care at a remote site in a real-time fashion with networked computers thus maintaining the integrity of immunohematology test results. It has taken the advantages of information and communication technologies to ensure the accuracy of patient, specimen and blood component identification and to enhance personnel traceability and system security. The built-in logics and process constraints in the design of the virtual blood bank can guide the selection of appropriate blood and minimize transfusion risk. The quality of blood inventory is ascertained and monitored, and an audit trail for critical procedures in the transfusion process is provided by the paperless system. Thus, the virtual blood bank can help ensure that the right patient receives the right amount of the right blood component at the right time. PMID:21383930

Double pendulum contact problem  

Directory of Open Access Journals (Sweden)

Full Text Available The work concerns contact problems focused on biomechanical systems modelled by a multibody approach. The example is modelling of impact between a body and an infrastructure. The paper firstly presents algorithm for minimum distance calculation. An analytical approach using a tangential plain perpendicular to an initial one is applied. Contact force generated during impact is compared by three different continuous force models, namely the Hertz’s model, the spring-dashpot model and the non-linear damping model. In order to identify contact parameters of these particular models, the method of numerical optimization is used. Purpose of this method is to find the most corresponding results of numerical simulation to the original experiment. Numerical optimization principle is put upon a bouncing ball example for the purpose of evaluation of desirable contact force parameters. The contact modelling is applied to a double pendulum problem. The equation of motion of the double pendulum system is derived using Lagrange equation of the second kind with multipliers, respecting the contact phenomena. Applications in biomechanical research are hinted at arm gravity motion and a double pendulum impact example.

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.

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Neste artigo consideramos que o fracasso escolar é um fenômeno persistente que exige análises empíricas e teóricas acerca dos processos de significação envolvidos na dinâmica das interações professor-aluno relacionados com as relações ensino-aprendizagem. Com base na abordagem sociocultural construt [...] ivista, o estudo analisa a interação de fatores socioculturais com a participação ativa do indivíduo, destacando a unidade cognição-afeto. Os processos interativos 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 sociocultura [...] l theoretical framework, which stresses the interactions between sociocultural factors and human agency, claiming for the unison, intertwined nature of affect and cognition. Interactive 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.

Virtual Human Problem Solving Environments  

Energy Technology Data Exchange (ETDEWEB)

Abstract. Interest in complex integrated digital or virtual human modeling has seen a significant increase over the last decade. Coincident with that increased interest, Oak Ridge National Laboratory (ORNL) initiated the development of a human simulation tool, the Virtual Human. The Virtual Human includes a problem-solving environment (PSE) for implementing the integration of physiological models in different programming languages and connecting physiological function to anatomy. The Virtual Human PSE (VHPSE) provides the computational framework with which to develop the concept of a "Virtual Human." Supporting the framework is a data definition for modeling parameters, PhysioML, a Virtual Human Database (VHDB), and a Web-based graphical user interface (GUI) developed using Java. Following description of the VHPSE, we discuss four example implementations of models within the framework. Further expansion of a human modeling environment was carried out in the Defense Advanced Research Projects Agency Virtual Soldier Project. SCIRun served as the Virtual Soldier problem solving environment (VSPSE). We review and compare specific developments in these projects that have significant potential for the future of Virtual Human modeling and simulation. We conclude with an evaluation of areas of future work that will provide important extensions to the VHPSE and VSPSE and make possible a fully-integrated environment for human anatomical and physiological modeling: the Virtual Human.

The contact caveat: negative contact predicts increased prejudice more than positive contact predicts reduced prejudice.  

Science.gov (United States)

Contact researchers have largely overlooked the potential for negative intergroup contact to increase prejudice. In Study 1, we tested the interaction between contact quantity and valence on prejudice toward Black Australians (n = 1,476), Muslim Australians (n = 173), and asylum seekers (n = 293). In all cases, the association between contact quantity and prejudice was moderated by its valence, with negative contact emerging as a stronger and more consistent predictor than positive contact. In Study 2, White Americans (n = 441) indicated how much positive and negative contact they had with Black Americans on separate measures. Although both quantity of positive and negative contact predicted racism and avoidance, negative contact was the stronger predictor. Furthermore, negative (but not positive) contact independently predicted suspicion about Barack Obama's birthplace. These results extend the contact hypothesis by issuing an important caveat: Negative contact may be more strongly associated with increased racism and discrimination than positive contact is with its reduction.

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.

The ethnography of virtual reality  

Directory of Open Access Journals (Sweden)

Full Text Available This paper discusses possible application of ethnographic research in the realm of virtual reality, especially in the relationship between cultures in virtual communities. This represents an entirely new area of ethnographic research and therefore many adjustments in the research design are needed for example, a development of a specific method of data gathering and tools for their verification. A virtual, cyber space is a version of social space more or less synchronous with it, but without the, "real", that is, physical presence of the people who create it. This virtual reality, defined and bounded by virtual space, is in fact real - and though we are not able to observe real, physical parameters of its existence, we can perceive its consequences. In sum, an innovative ethnographic research method is fully applicable for exploring the realm of virtual reality; in order to do so we need to expand, in addition to the new research design and methods, the field of science itself.

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.

Physical culture as a phenomenon of the development of socio-cultural competence of future teachers of physical education  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose : to substantiate the phenomenon of formation of physical culture of the individual in terms of theoretical and methodological approaches to the development of socio-cultural competence of future teachers. Material : 22 literary sources analyzed on the issue of formation of physical culture of the individual. Used cultural studies, axiological and competence approach. Results : define the concept of socio-cultural competence of the teacher of physical education. Competence is considered as an integrative motivational tumor - activity sphere of the individual. It determines the focus of an expert on the formation of spiritual values and is the foundation for its further self-development. Disclosed structure sociocultural competence of the teacher in the unity components: cognitive, motivational-value, behavioral. For each component defined system of spiritual values. The system covers the socio- psychological, mental and cultural values of physical culture. Conclusions : the sociocultural competence of the teacher of physical education meaningful and functionally related to the values of the physical culture of the individual. Spiritual, value the personality of the teacher - is the foundation for all of the components of socio-cultural competence. This competence provides social and cultural development of the individual.

Full Text Available Sociocultural theory has made a great impact on the learning and teaching profession. The theory advocates learning, including L2 acquisition, as a semiotic process where participation in socially mediated activities is essential. It regards instruction as crucial to L2 development and should be geared to the Zone of Proximal Development (ZPD that is beyond the learner?s actual development level. It believes that learning in an L2 context should be a collaborative achievement and not an isolated individual?s effort where the learner works unassisted and unmediated. This literature review discusses the relevance and implications of this theory to L2 teaching.

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

Digital Repository Infrastructure Vision for European Research (DRIVER)

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 spi...

The Dubai Community Psychiatric Survey: II. Development of the Socio-cultural Change Questionnaire.  

Science.gov (United States)

The Dubai Community Psychiatric Survey was carried out to assess the effect of very rapid social change on the mental health of women in Dubai, one of the United Arab Emirates. In order to measure social change at an individual level, we developed a questionnaire covering behaviour and attitudes in a wide range of situations, the Socio-cultural Change Questionnaire (ScCQ). In this paper we give an account of the considerations that determined the form of the ScCQ, its structural characteristics, and its validity. PMID:8511664

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.

STEM education: A deficit framework for the twenty first century? A sociocultural socioscientific response  

Science.gov (United States)

The ubiquitous of STEM education initiatives in recent years has created a bandwagon that has moved at nearly light speed. The impulse of the science education community and policy-makers is to grab hold for dear life or be marginalized from subsequent discussions about the necessity and consequences of using STEM initiatives to prepare and inform our next generation of citizens. This commentary questions the prudence of STEM-related science education goals, as typically represented and discussed in the literature, and likens the current practice to a deficit framework. A sociocultural perspective framed through socioscientific considerations is offered as an alternative conceptualization as well as surplus model to hegemonic STEM practices.

Sociocultural Theory Applied to Second Language Learning: Collaborative Learning with Reference to the Chinese Context  

Directory of Open Access Journals (Sweden)

Full Text Available This paper discusses the sociocultural theory (SCT. In particular, three significant concepts of Vyogtsky’s theory: self-regulation, the Zone of Proximal Development (ZPD, and scaffolding all of which have been discussed in numerous second language acquisition (SLA and second language learning (SLL research papers. These concepts lay the psychological foundation for collaborative learning, the subject of this paper. This publication aims to examine SCT by assessing collaborative learning within the Chinese context. This paper focuses on teacher-student collaboration and it concludes that the perceived way of learning and teaching and teacher-student relationship should be changed in order to implement collaborative learning.

Interactive Virtual Cinematography  

DEFF Research Database (Denmark)

A virtual camera represents the point-of-view of the player through which she perceives the game world and gets feedback on her actions. Thus, the virtual camera plays a vital role in 3D computer games and aects player experience and enjoyability in games. Interactive virtual cinematography is the process of visualising the content of a virtual environment by positioning and animating the virtual camera in the context of interactive applications such as a computer game. Camera placement and animation in games are usually directly controlled by the player or statically predened by designers. Direct control of the camera by the player increases the complexity of the interaction and reduces the designer's control on game storytelling. A completely designer-driven camera releases the player from the burden of controlling the point of view, but might generate undesired camera behaviours. Furthermore, if the content of the game is procedurally generated, the designer might not have the necessary information to dene a priori the camera positions and movements. Automatic camera control aims to dene an abstraction layer that permits to control the camera using high-level and environment-independent rules. The camera controller should dynamically and eciently translate these rules into camera positions and movements before (or while) the player plays the game. Automatically controlling the camera in virtual 3D dynamic environments is an open research problem and a challenging task. From an optimisation perspective it is a relatively low dimensional problem (i.e. it has a minimum of 5 dimensions) but the complexity of the objective function evaluation combined with the strict time constraints make the problem computationally complex. Moreover, the multi-objective nature of the typical camera objective function, introduces problems such as constraints conflicts, over-constraining or under-constraining. An hypothetical optimal automatic camera control system should provide the right tool to allow designers to place cameras eectively in dynamic and unpredictable environments. However, there is still a limit in this approach: to bridge the gap between automatic and manual cameras the camera objective should be influenced by the player. In our view, the camera control system should be able to learn camera preferences from the user and adapt the camera setting to improve the player experience. Therefore, we propose a new approach to automatic camera control that indirectly includes the player in the camera control loop. To achieve this goal we have analysed the automatic camera control problem from a numerical optimization perspective and we have introduced a new optimization algorithm and camera control architecture able to generate real-time, smooth and well composed camera animations. Moreover, we have designed and tested an approach to model the player's camera preferences using machine learning techniques and to tailor the automatic camera behaviour to the player and her game-play style. Experiments show that, the novel optimisation algorithm introduced successfully handles highly dynamic and multi-modal tness functions such as the ones typically involved in dynamic camera control. Moreover, when applied in a commercial-standard game, the proposed automatic camera control architecture shows to be able to accurately and smoothly control the camera. Finally, the results of a user survey, conducted to evaluate the suggested methodology for camera behaviour modelling and adaptation, shows that the resulting adaptive cinematographic experience is largely favoured by the players and it generates a positive impact on the game performance.

Prolongation on Contact Manifolds  

CERN Document Server

On contact manifolds we describe a notion of (contact) finite-type for linear partial differential operators satisfying a natural condition on their leading terms. A large class of linear differential operators are of finite-type in this sense, and for any such operator we construct a partial connection on a (finite rank) vector bundle with the property that sections in the null space of the operator correspond bijectively, and via an explicit map, with sections parallel for the partial connection. It follows that the solution space is finite dimensional and bounded by the corank of the holonomy algebra of the partial connection. For finite-type operators on a parabolic contact geometry, the structure of the vector bundle, in particular its rank, can be easily determined by representation theory.

Adapting Virtual Camera Behaviour  

DEFF Research Database (Denmark)

In a three-dimensional virtual environment aspects such as narrative and interaction completely depend on the camera since the camera defines the player’s point of view. Most research works in automatic camera control aim to take the control of this aspect from the player to automatically gen- erate cinematographic game experiences reducing, however, the player’s feeling of agency. We propose a methodology to integrate the player in the camera control loop that allows to design and generate personalised cinematographic expe- riences. Furthermore, we present an evaluation of the afore- mentioned methodology showing that the generated camera movements are positively perceived by novice asnd intermediate players.

The virtual cathode chamber  

CERN Document Server

We describe the operating principle and the first experimental results obtained with gas micro-strip detectors realized with anodes only on the active side, the multiplying field being provided from the back-plane and drift electrodes. For high rate operation, the detector has to be implemented on electron conducting supports, with resistivity around 10$^{11}\\Omega$? cm. By construction, the ³Virtual Cathode Chamber² is not subjected to the possibility of discharges between anodes and cathodes, thus avoiding one of the most dangerous problems met with standard micro-strip chambers.

Alice - The Virtual Secretary  

DEFF Research Database (Denmark)

Animated Agents are increasingly finding their way into computer applications and websites. They create life on the screen for us, attempt to personalize our communication and rather than us being forced to read long website introductions, they can verbally introduce us to the content. One of the primary ideas behind using animated agents is, quoting Wik and Granström (2007), to transform the well-known desktop metaphor of the PC, into a more human metaphor, thereby increasing the authenticity of our interaction with technology. At Knowledge Lab we have combined three different technologies in order to create Alice – The virtual secretary.

Visual distance estimation in static compared to moving virtual scenes.  

Science.gov (United States)

Visual motion is used to control direction and speed of self-motion and time-to-contact with an obstacle. In earlier work, we found that human subjects can discriminate between the distances of different visually simulated self-motions in a virtual scene. Distance indication in terms of an exocentric interval adjustment task, however, revealed linear correlation between perceived and indicated distances but with a profound distance underestimation. One possible explanation for this underestimation is the perception of visual space in virtual environments. Humans perceive visual space in natural scenes as curved, and distances are increasingly underestimated with increasing distance from the observer. Such spatial compression may also exist in our virtual environment. We therefore surveyed perceived visual space in a static virtual scene. We asked observers to compare two horizontal depth intervals, similar to experiments performed in natural space. Subjects had to indicate the size of one depth interval relative to a second interval. Our observers perceived visual space in the virtual environment as compressed, similar to the perception found in natural scenes. However, the nonlinear depth function we found can not explain the observed distance underestimation of visual simulated self-motions in the same environment. PMID:17120711

When Virtual Worlds Expand  

Science.gov (United States)

The future of a virtual world depends on whether it can grow in subjective size, cultural content, and numbers of human participants. In one form of growth, exemplified by Second Life, the scope of a world increases gradually as new sponsors pay for new territory and inhabitants create content. A very different form of growth is sudden expansion, as when World of Warcraft (WoW) added entire new continents in its Burning Crusade and Lich King expansions (Lummis and Kern 2006, 2008; Corneliussen and Rettberg 2008; Sims et al. 2008). Well-established gamelike worlds have often undergone many expansions. Both the pioneer science fiction game Anarchy Online, which was launched in 2001, and Star Wars Galaxies dating from 2003, have had three, and EVE Online also from 2003 has had nine, although smaller ones. This chapter reports research on WoW's 2008 Lich King expansion, using both quantitative and qualitative methods, in order to develop theoretical ideas of the implications of expansion for virtual worlds.

Quantitative embedded contact homology  

CERN Document Server

Define a "Liouville domain" to be a compact exact symplectic manifold with contact-type boundary. We use embedded contact homology to assign to each four-dimensional Liouville domain (or subset thereof) a sequence of real numbers, which we call "ECH capacities". The ECH capacities of a Liouville domain are defined in terms of the "ECH spectrum" of its boundary, which measures the amount of symplectic action needed to represent certain classes in embedded contact homology. Using cobordism maps on embedded contact homology (defined in joint work with Taubes), we show that the ECH capacities are monotone with respect to symplectic embeddings. We compute the ECH capacities of ellipsoids, polydisks, certain subsets of the cotangent bundle of T2, and disjoint unions of examples for which the ECH capacities are known. The resulting symplectic embedding obstructions are sharp in some interesting cases, for example for the problem of embedding an ellipsoid into a ball (as shown by work of McDuff-Schlenk) or embedding ...

[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

[Contact allergies in musicians].  

Science.gov (United States)

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. PMID:23233303

Asian flushing: genetic and sociocultural factors of alcoholism among East asians.  

Science.gov (United States)

Alcohol use can lead to a cascade of problems such as increased chances of risky behavior and negative health consequences, including alcoholic liver disease and upper gastric and liver cancer. Ethanol is metabolized mainly by 2 major enzymes: alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH). Genetic variations of genes encoding the 2 enzymes are very common among East Asians but relatively rare for most other populations. Facial flushing and other physical discomforts after alcohol drinking triggered by accumulation of acetaldehyde through defective genes for ADH and ALDH have been reported. Approximately 40% of East Asians (Chinese, Japanese, and Korean) show facial flushing after drinking alcohol, known as "Asian flush," which is characterized by adverse reactions on alcohol drinking in individuals possessing the fasting metabolizing alleles for ADH, ADH1B*2, and ADH1C*1, and the null allele for ALDH and ALDH2*2. Alcoholism is determined not only by the genetic deficiency but also by behaviors that involve complex interactions between genetic and sociocultural factors. The purpose of this article was to provide nurses with the most current information about genetic and sociocultural influences on alcoholism and alcohol-related health problems specifically for East Asians and implications of this knowledge to nursing practice. The physiological phenomenon of genes and genetics in relation to alcohol metabolism in this special population is emphasized. PMID:25271825

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

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English 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 sourc [...] e 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 chewing. 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.

`Brown Paper Packages'? A Sociocultural Perspective on Young Children's Ideas in Science  

Science.gov (United States)

How do we see young children's thinking in science? Is it, as much previous research has led us to believe, that their ideas can be neatly boxed like “brown paper packages tied up with strings” - as the song from The Sound of Music goes? Or are their ideas like “wild geese that fly with the moon on their wings” ( Sound of Music): fluid, complex, rich. . .? Drawing on the author's research into young children's ideas about natural phenomena such as the rain and clouds, and on Rogoff's three foci of analysis (personal, interpersonal and contextual), this paper illustrates how a consideration of sociocultural theory can be useful in framing research with young children, and allow us to see beyond the boxes. Emphasis is placed on recognising that children's thinking in science is embedded within particular sociocultural contexts, is guided by others and integrated with their use of certain mental and physical cultural tools. Thus, the article aims to present an alternative method for the generation of data on young children's thinking. Specific analysis of this data will, it is intended, be presented in a subsequent article.

Teachers Role As A Transmited On Socio-Cultural Constitution At Cyprus Turkish Community  

Directory of Open Access Journals (Sweden)

Full Text Available Every socio-cultural constitution is the complement of organizations which exists by means of economy, politics, religion, education and family. Education is both an organization and a process of socialization from the sociological perspective. Education is a process that is affected and conformed by the society, affects and conforms the society, can change as the society changes and also changes the society with the parallelism of its change. Teachers are the most significant managers of this organization. Teaching is an important profession with its quality and function which enables the society to develop in each field and keep on its existence. The role of education and teachers can not be ignored for Cypriot Turkish Community that is located on a geo-strategic geography during ages.In this study, it is aimed to explain and clarify how Cypriot Turkish community, which had to survive under the Direction of English colony for 82 years, have been able to transmit its socio-cultural structure to the future by the excellent aid of education and teachers despite the physical impossibility and domination.

Science.gov (United States)

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 valuation of ecosystem services in a transhumance social-ecological network  

DEFF Research Database (Denmark)

The ecosystem services framework is receiving increasing attention in the fields of policy and research. The assessment of human attitudes and perceptions regarding ecosystem services has been proposed as a promising tool for addressing complex problems associated with environmental change, particularly in the context of cultural landscapes. Transhumance is not only a farming practice responsible for shaping cultural landscapes but also an adaptive strategy based on mobility that may represent a useful approach to overcoming the growing challenges posed by accelerated environmental change. A socio-cultural valuation of ecosystem services associated with the Conquense Drove Road, one of the major transhumant networks still in use in Mediterranean Spain, was conducted via the distribution of questionnaires to 416 local residents and visitors to capture their perceptions regarding the importance of 34 ecosystem services (10 provisioning, 12 regulating, and 12 cultural) for both social and personal well-being. Overall, the ecosystem services considered to be the most important for social well-being were fire prevention, air purification and livestock. Most of the ecosystem services in question were perceived as declining, with the exception of those associated with recreation, scientific knowledge and environmental education. This study revealed that perceptions regarding the value of ecosystem services differed among respondents, depending on their age, place of origin and gender. Several methodological issues, as well as the impl
