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?
We give a construction of contact homology in the sense of Eliashberg--Givental--Hofer. Specifically, we construct coherent virtual fundamental cycles on the relevant compactified moduli spaces of pseudo-holomorphic curves.

Business models for transnational organizations include linking different geographies through common codes of conduct, policies, and virtual teams. Global companies with laboratory animal science activities (whether outsourced or performed inhouse) often see the need for these business activities in relation to animal-based research and benefit from them. Global biomedical research organizations can learn how to better foster worldwide cooperation and teamwork by understanding and working with sociocultural differences in ethics and by knowing how to facilitate appropriate virtual team actions. Associated practices include implementing codes and policies transcend cultural, ethnic, or other boundaries and equipping virtual teams with the needed technology, support, and rewards to ensure timely and productive work that ultimately promotes good science and patient safety in drug development.

Full Text Available En éste trabajo se presenta la organización y seguimiento del prácticum en el marco de una universidad virtual. Desde una visión constructivista y sociocultural de la enseñanza, del aprendizaje y de la evaluación, la propuesta plantea un modelo de prácticum de la licenciatura de 2º ciclo de Psicopedagogía, que conjuga la tutorización y el seguimiento del trabajo de los estudiantes en el centro de prácticas simultáneamente con un trabajo de reflexión sobre la práctica que se lleva a cabo en el aula del campus virtual. La aplicación de esta metodología aporta muchos beneficios formativos para los estudiantes puesto que garantiza la adquisición de destrezas propias de la intervención psicopedagógica en un contexto determinado conjuntamente con la reflexión sobre los contextos, finalidades y objetivos de la intervención psicopedagógica. Las repercusiones, ventajas e inconvenientes de éste modelo de prácticum se analizan teniendo en cuenta también las directrices del Espacio Europeo de Educación Superior.ABSTRACTUsing the virtual campus in the practicum of psychopedagogy: a socio-cultural and constructivist approach. The Practicum (post-graduate teacher education is an area critical to the formation of a student to finish college.In the new framework of European Higher Education Area(EHEA,classroom practices have become even more important for the development of the skills required for a particular professional profile. In this paper we present the organization and monitoring of the Practicum as part of a virtual university. From a constructivist and socio-cultural teaching, learning and assessment, the proposal presents a model of practicum of the degree of 2nd cycle of psychopedagogy, which combines mentoring and monitoring the work of students in the training center work simultaneously with a reflection on practice which takes place in the classroom of the virtual campus. The results are analyzed from the satisfaction questionnaire administered to students at the end of each semester, which assesses four areas: overall satisfaction, teaching activities, resources and assessment of learning. The application of this methodology has many benefits for students training as skill acquisition warrants intervention own psychology in context togetherwith reflection on the contexts, purposes and objectives of the psychopedagogy intervention. The implications, advantages and disadvantages of this model of practicum are discussed taking into account the guidelines of the European Higher Education Area.
A common question is whether technology will replace social contact. In this article it is argued that it will not, provided that we learn to use the characteristics of new media constructively in designing for learning. The term social, in this context is taken to mean purposeful communication and not recreational socializing (even if socializing may indeed facilitate learning)

Abstract This research examined virtualhuman interactions as a new form of simulated contact between members of groups in conflict. A virtual human representing an outgroup member (a Palestinian) interacted with 60 Jewish Israeli participants in an experimental study. We manipulated postural mimicry by the virtual interaction partner during a conversation about a sensitive conflict issue. Mimicry increased empathy toward the Palestinians, irrespective of participants' feelings toward the Palestinians prior to the experiment. Further, mimicked participants who reported a priori negative feelings toward Palestinians expressed more sympathy toward their Palestinian virtual interaction partner, rated themselves as closer to him, and perceived the interaction as more harmonious compared to participants in a counter-mimicry condition. The results underscore the impact of mimicry on intergroup interactions, especially on individuals who harbor negative feelings toward the outgroup. The use of virtualhuman interactions in obtaining this effect reveals the still widely unexplored potential of technology-enhanced conflict resolution. PMID:25343577

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

The virtual prototypes of gear transmission system built in most multi-body dynamic software have difficulties in describing the gear mesh characteristics. The gear mesh contact is modelled as rigid contact and this is not accurate for the gear mesh contact, which is elastic or flexible. The gear contact formula used in the multi-body dynamic software does not reveal the gear contact nonlinear stiffness characteristic. The model built with gear meshing contact is difficult to solve because of its time-consuming algorithm. In the paper a new method is put forward to build the virtual prototype of planetary gearbox system according to the nonlinear mesh stiffness and mesh phase obtained through FEM models. This new FEM method of gear mesh stiffness calculation is much more accurate than the common formulas. The gear mesh nonlinear stiffness of sun gear- pinion and pinion-ring gear of all the planetary gear sets in gearbox are obtained through MATALB code, which is used to read and plot the analyzing result data. The gear mesh phase differences between different pinions with suns or rings of different planetary gear set can be also obtained. With all these data modelled in simulink (or other software) and integrated with the multi-body dynamic planetary gearbox model and the gear meshing contact problem in multi-body gear models is solved easily and accurately. The interfaces for gear mesh stiffness and mesh phases are designed for multi-body dynamic model and simulink. The nonlinear planetary gear set prototyping models are integrated to become the whole planetary gear box model and the whole vehicle system model built in multi-body dynamic software can be integrated to simulate different duty conditions. At last high speed input is put into the nonlinear planetary transmission model and the different duty cases are simulated. The dynamic characteristics of different parts are obtained. The dynamic characteristic comparison between nonlinear and linear models is made. It solves the difficulty of gear contact simulation in multi-body dynamic model and provides a new method in gear mesh stiffness calculation, which exports simulationX (or other software) model of nonlinear gear stiffness to replace that in multi-body dynamic model and succeeds in integrating planetary gear transmission with other parts of the vehicle. According to the simulation results, the conclusion can be made that the nonlinear modelling method for planetary gearbox is reliable and practical. It can be used to evaluate vibration characteristic of planetary gear transmission with high speed input
Full Text Available Alexey B Mantsyzov,1 Guillaume Bouvier,2 Nathalie Evrard-Todeschi,1 Gildas Bertho11UniversitÃ© 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

The reported research uses an extension of Bartlett's method of repeated reproduction to provide data on the sociocultural processes underlying reconstructive remembering. Twenty participants worked in pairs to remember the War of the Ghosts story 15 min and 1 week after presentation. The observed......, questioning and deferring contribute to the transformation and conventionalization of the material. These diverse sociocultural mediators are integrated into a partially coherent recollection by participants self-reflecting, or as Bartlett termed it, turning around upon their schemas. We demonstrate that this...

During the process of human childbirth, obstetric forceps delivery can be a justified alternative to emergency Caesarean section when normal vaginal delivery proves difficult or impossible. Currently, training of forceps interventions is mainly done on real patients which poses a risk. This paper describes a pilot project on the simulation of training of obstetric forceps delivery, using Virtual Reality technology. We first give a brief historical review of the concept of 'birth simulation' and describe the current implementation of the interface. Then we report a number of experiments, conducted to test the feasibility of a real-time mechanical contact model to describe the interaction between the forceps and fetal head, eventually to be interfaced with a multi-purpose haptic feedback device. It is concluded that an explicit dynamic model to calculate the deformation of the main fetal skull bones only, or a quasi-static model to calculate the deformation of the fetal head in its entirety, can reach real-time performance.

The process of cross-cultural migration may be particularly difficult for students travelling overseas for further or higher education, especially where qualitative differences exist between the home and host nations. The present study examined the sociocultural adjustment of sojourning Malaysian students in Britain. Eighty-one Malay and 110 Chinese students enrolled in various courses answered a self-report questionnaire that examined various aspects of sociocultural adjustment. A series of one-way analyses of variance showed that Malay participants experienced poorer sociocultural adjustment in comparison with their Chinese counterparts. They were also less likely than Chinese students to have contact with co-nationals and host nationals, more likely to perceive their actual experience in Britain as worse than they had expected, and more likely to perceive greater cultural distance and greater discrimination. The results of regression analyses showed that, for Malay participants, perceived discrimination accounted for the greatest proportion of variance in sociocultural adjustment (73%), followed by English language proficiency (10%) and contact with host nationals (4%). For Chinese participants, English language proficiency was the strongest predictor of sociocultural adjustment (54%), followed by expectations of life in Britain (18%) and contact with host nationals (3%). By contrast, participants' sex, age, and length of residence failed to emerge as significant predictors for either ethnic group. Possible explanations for this pattern of findings are discussed, including the effects of Islamophobia on Malay-Muslims in Britain, possible socioeconomic differences between Malay and Chinese students, and personality differences between the two ethnic groups. The results are further discussed in relation to practical steps that can be taken to improve the sociocultural adjustment of sojourning students in Britain. PMID:22029555

En todos ellos se analizan los aspectos divergentes, pero también los que favorecen la complementación, lo cual no niega la existencia de una fuerte tendencia a la polarización entre ambas disciplinas, que, sin embargo, consideramos que podemos reducir y superar a través de procedimientos que favorecen el desarrollo de una epidemiología sociocultural pensada no como disciplina diferenciada, sino como una articulación entre los enfoques epidemiológicos y los socioantropológicos.

Divergent and convergent issues are analyzed for all these topics, which does not negate a strong trend toward polarization between both disciplines. Even so, we consider that this can be reduced and surmounted through strategies aimed at developing a sociocultural epidemiology conceived not as a discipline but as a link between epidemiological and anthropological approaches. One of the main strategies is a reflection on the health process under study, which includes an in-depth discussion of the researchers' own theoretical, empirical and technical assumptions.
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)

Virtual worlds (VWs) are computer-simulated environments which allow users to create their own virtual character as an avatar. With the rapidly growing user volume in VWs, platform providers launch virtual goods in haste and stampede users to increase sales revenue. However, the rapidity of development incurs virtual unrelated items which will be difficult to remarket. It not only wastes virtual global companies' intelligence resources, but also makes it difficult for users to find suitable virtual goods fit for their virtual home in daily virtual life. In the VWs, users decorate their houses, visit others' homes, create families, host parties, and so forth. Users establish their social life circles through these activities. This research proposes a novel virtual goods recommendation method based on these social interactions. The contact strength and contact influence result from interactions with social neighbors and influence users' buying intention. Our research highlights the importance of social interactions in virtual goods recommendation. The experiment's data were retrieved from an online VW platform, and the results show that the proposed method, considering social interactions and social life circle, has better performance than existing recommendation methods.

We argue that thermal machines can be understood from the perspective of `virtual qubits' at `virtual temperatures': The relevant way to view the two heat baths which drive a thermal machine is as a composite system. Virtual qubits are two-level subsystems of this composite, and their virtual temperatures can take on any value, positive or negative. Thermal machines act upon an external system by placing it in thermal contact with a well-selected range of virtual qubits and ...

An introduction to the subculture is understood as one of the stages of individualization and formation of the young person as a member of society. In the described study, we tested the assumption that the orientation of adolescents on a subculture or the dominant culture is due to different sociocultural determinants (society, small group and personality. The participants were 304 high schools students, average age 15.2 years. With the use of a number of diagnostic techniques and factor analysis, we revealed the sociocultural determinants of adolescentsâ orientation on the dominant culture or gamers subculture. Experts attention is drawn to the consideration of the specific of identified sociocultural determinants that will boost the effectiveness of the preventive and remedial work programs aimed at developing in teenagers the means of constructive intercultural interaction, focused on different levels of the organization culture.

Stress of any kind can act as a precipitating factor. We report here a patient of anorexia nervosa, in whom the above men...
Full Text Available Socio-cultural factors â shared values, norms and attitudes are significant, but less acknowledged sources of international competitiveness. Previous studies have found socio-cultural factors positively affecting various aspects of international competitiveness â entrepreneurship, innovation, productivity and international cooperation. These factors are more sustainable and less affected by external environment changes in comparison with the traditional factors. Socio-cultural factors provide an opportunity to develop competitiveness strategies based on unique advantages. This research aims to explore the impact of socio-cultural factors on international competiveness in small, open economies. Analysing relationship between 400 socio-cultural indicators and competitiveness indicators such as productivity, economic development, business and government efficiency, innovation capacity and infrastructure in 37 countries, six socio-cultural factors have emerged: Collectivism and Hierarchy; Future, Cooperation and Performance Orientation, Self-expression, Monochronism and Rationality, Economic Orientation and Social structure. The first factor â Collectivism and Hierarchy â tends to reduce the international competitiveness; the other five affect it positively.

The topic of the paper is devoted to analysis of socio-cultural impacts of tourism, as effects on the people of host communities resulting from their direct and indirect associations with tourists. The social and cultural impacts of tourism are the ways in which tourism is contributing to changes in value systems, individual behavior, family structure and relationships, collective lifestyles, safety levels, moral conduct, traditional ceremonies and community organizations. Special attention is devoted to considering complexity of tourists/host interrelationships and discussing the techniques for appraisal of quality and quantity of socio-cultural changes which tourism provokes in local communities.

This study seeks to explore and explain the socio-cultural factors responsible for the incidence of infant malnutrition in Cameroon with particular emphasis on northern Cameroon where it is most accentuated. It combines quantitative data drawn from the 1991, 1998, 2004 and 2011 Cameroon Demographic and Health Surveys, as well as a literature review of publications by the WHO and UNICEF. This is further complemented with qualitative data from various regions of Cameroon, partly from a national ethnographic study on the ethno-medical causes of infertility in Cameroon conducted between 1999 and 2000. Whereas socio-cultural factors related to child feeding and maternal health (breast-feeding, food taboos and representations of the colostrum as dangerous for infants) are widespread throughout Cameroon, poverty-related factors (lack of education for mothers, natural disaster, unprecedented influx of refugees, inaccessibility and inequity in the distribution of health care services) are pervasive in northern Cameroon. This conjunction of factors accounts for the higher incidence of infant malnutrition and mortality in northern Cameroon. The study suggests the need for women's empowerment and for health care personnel in transcultural situations to understand local cultural beliefs, practices and sentiments before initiating change efforts in infant feeding practices and maternal health. Biomedical services should be tailored to the social and cultural needs of the target population--particularly women--since beliefs and practices underpin therapeutic recourse. Whereas infant diarrhoea might be believed to be the result of sexual contact, in reality, it is caused by unhygienic conditions. Similarly, weaning foods aimed at transmitting ethnic identity might not meet a child's age-specific food needs and might instead give rise to malnutrition. PMID:24717356

Full Text Available I present a sociocultural approach to research and science education that incorporates a recursive relationship between transformation and theory, acknowledges the strengths of subjectivity, and regards difference as a resource for learning. 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.

This paper examines how the effects of virtual space on learning have been elucidated in recent research with the aim of providing both a comprehensive picture of the current state of research and interesting avenues for future projects. Drawing on a multidisciplinary review, it identifies five key themes that together constitute research in virtual space and learning: analogies between the study of physical space and learning; socio-cultural constructivist perspectives; practical and theoret...
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 individuals internal cognitive process cannot account for developmental process. The researchers should also consider the external social factors in the childs 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 childs zone of proximal development (ZPD and also successful learning process cannot be an individuals unmediated or unassisted effort but a collaborative process.

Full Text Available The history of Brazilian neuropsychology is traced at different neuropsycholinguistic stages with a focus on the importance of sociocultural factors. We first focus on language disorders, the sequelae of injuries in the left hemisphere, and neuropsychology restricted to the medical field in Europe, the United States, and Brazil. In the middle of the last century, attention to the interdisciplinary importance of studies on the right hemisphere began. Studies consequently emerged on the individual variability of brain function with both biological and cultural origins. Based on this approach, Brazilian studies on aphasic children and illiterate aphasic persons were disseminated internationally. In the 1970s, cognitive neuropsychology began in England, highlighting dysfunctions in reading and writing processes. The characteristics of writing systems within each language became relevant for the manifestations of acquired dyslexia. Brazilian studies showed deficits in Portuguese and Japanese writing caused by brain lesions. During this scientific journey, scientific societies and postgraduate programs in Brazil were created to facilitate exchanges and communication among young researchers. By the end of the last century and in the early 2000s, the growth of the neuropsychology of aging raised awareness of the complexity of sociocultural factors, not only on language research but also according to the level of education, frequency of reading and writing habits, school type, and interactions among these factors and biological factors, especially between the level of education and age. From this historical standpoint, we outline future directions and perspectives in the field of Brazilian neuropsychology.
Purpose: To examine philosophical stances underpinning medical identity and assess the conceptual relationship between physician, medical practice and culture. Argument: Medical identity is about the ideals and moral positions that physicians take when justifying themselves. Medical identity is the study of the sociocultural paragons that conceptually underlie the phenomenology of physicians coming to take themselves as autonomous social agents. The paper relies on Hegels Phenomenology of Spirit and investigates dilemmas pertaining to first objectivist versus subjectivist views and second hedonistic versus sentimentalist approaches to medical identity. The sociocultural philosophical analysis of medical identity can shed light on what it means conceptually for a physician to harbor beliefs associated with him/her being taken to be an autonomous professional. It is important because it touches on the meaning of being a compassionate, good and skilled physician, making its relevance to person-centered medicine self-evident. Conclusion: Medical identity should be analyzed with reference to literature, philosophy and medical practice in order for the physician to exercise a reflective position in the care of the individual patient which is both scientifically rational and subjectively meaningful.

Virtual objects are objects thought up by a thinking individual. Although 20th-century philosophy has tried to ban them from ontology, they make it impossible to account for the truth of sentences such as Apollo was worshipped in the island of Delos, in which a property is assigned to the nonexisting, virtual entity Apollo. Such facts are the reason why virtual objects are slowly being recognized again.

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.)

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

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.

In the 1970's, when computers were memory limited, operating system designers created the concept of ''virtual memory'' which gave users the ability to address more memory than physically existed. In the 1990s, many large control systems have the potential for becoming data limited. We propose that many of the principles behind virtual memory systems (working sets, locality, caching, and clustering) can also be applied to data-limited systems - creating, in effect, ''virtual data systems.'' At the Los Alamos National Laboratory's Clinton P. Anderson Meson Physics Facility (LAMPF), we have applied these principles to a moderately sized (10,000 data points) data acquisition and control system. To test the principles, we measured the system's performance during tune-up, production, and maintenance periods. In this paper, we present a general discussion of the principles of a virtual data system along with some discussion of our own implementation and the results of our performance measurements

A growing body of research argues that teachers' beliefs and practices should be studied within the sociocultural contexts of their work because the relationship between their beliefs and practices is both complex and context-dependent. There is a need for further research in this area in understudied contexts such as developing countries, in order to promote effective education in schools and the professional development of teachers. This paper argues that if this `black box' of sociocultural contexts in which science teachers are embedded is better understood, it may be possible to identify specific aspects of these contexts related to educational organizations that act as either supports or barriers to pedagogical reform or to implementing innovations in science education. Consequently, the main purpose of this study is to explore the sociocultural contexts of ten Egyptian science teachers and to what extent these sociocultural contexts help in understanding teachers' pedagogical beliefs and practices. This paper, by utilizing a multi-grounded theory approach and qualitative methods, reveals a variety of sociocultural contexts that are related to teachers' pedagogical beliefs and practices.

Full Text Available El interés para realizar esta investigación surgió a partir de que Argentina recibe un número creciente de estudiantes de otros países latinoamericanos, atraídos por el idioma, el prestigio académico y las condiciones económicas. Como resultado del contacto intercultural, los estudiantes atraviesan [...] el proceso psicológico denominado aculturación, que implica cambios afectivos, comportamentales y cognitivos. En virtud de lo antedicho, este estudio se propuso identificar predictores de adaptación sociocultural en función de variables sociodemográficas, culturales y psicológicas de estudiantes que decidieron realizar sus estudios universitarios en Argentina. Participaron 216 estudiantes migrantes que se encontraban cursando diferentes carreras universitarias, el 57% eran mujeres (n = 124) y el 43% varones (n = 92), con un promedio de edad de 24.18 años (DE = 4.55). El 86% (n = 186) había nacido en Latinoamérica. El restante 14% provenía de países de Europa y Asia. El tiempo promedio de residencia en Argentina era de 3.31años. Se emplearon diferentes instrumentos diseñados ad hoc y/o adaptados para medir las variables involucradas en el estudio. A partir de los resultados obtenidos, no se pudo corroborar la influencia por parte de variables sociodemográficas (edad y tiempo de residencia). En cambio, entre las variables culturales se constató que percibir bajos niveles de discriminación y ansiedad intergrupal predice buenos niveles de adaptación sociocultural. En cuanto a las variables psicológicas, se corroboró que el apoyo social y la satisfacción percibida contribuyen a la adaptación sociocultural. En términos globales, las variables culturales y psicológicas predicen con mayor éxito la adaptación sociocultural en relación alas sociodemográficas. Abstract in english The interest of this research arises from that Argentina received a growing number of students from other Latin-American countries. International migration has risen exponentially in recent decades due to advances in technology and communications. According to the International Organization for Migr [...] ation (OIM, 2010), the estimated number of international migrants in the world for that year was 214 million, doubling the previous two decades. Globalization has promoted exchanges among different cultures, but also caused the collision between different value systems, beliefs and customs that, in many cases, generates situations of confusion or discomfort in people (Furnham & Bochner, 1986). Approximately 2.9million people each year decide to make or complete their studies in other countries (OECD, 2008). Argentina receives an increasing number of students from other Latin-American countries, attracted by the language, the academic prestige of the local universities and the favorable economic conditions (Filmus, 2007). At the present, international students represent 1.6% of university students in Argentina. Therefore, Argentina is the fourth host country of America, after United States, Canada and Uruguay. As a result of intercultural contact, students go through the psychological process called acculturation, which involves affective, behavioral and cognitive changes. Taking into account the antecedents mentioned, this research proposed to identify predictors of socio-cultural adaptation based on socio-demographic, cultural and psychological variables, in international students who decided to make their university studies in Argentina. The participants of the study were 216 migrant students who were studying different careers. 57% were women (n = 124) and 43% males (n = 92) with an average age of 24.18 years (SD = 4.55). 86% (n = 186) were born in Latin-America. The remaining 14% came from Europe and Asia. The average residence time in Argentina was 3.31 years. The reasons for their arrival in Argentina were diverse, 50% (n = 108) of them considered that Argentina was a good place to study for its academic prestige and low costs. The remaining half was divided between family reasons (n = 47, 21%),

Teleconferencing systems are becoming more popular because of advance in image processing and broadband network. Nevertheless, communicating with someone at a remote location through a teleconferencing system still presents problems because of the difficulty of establishing and maintaining eye contact. Eye contact is essential to having a natural dialog. The purpose of our study is to make eye contact possible during dialog by using image processing with no particular devices, such as color markers, sensors, which are equipped users with and IR cameras. Proposed teleconferencing system is composed of a computer, a display attached to the computer, and four cameras. We define virtual camera as the camera, which exists virtually in 3D space. By using the proposed method, we can acquire a front view of a person that is taken with the virtual camera. The image taken with virtual camera is generated by extracting a same feature point among four face images. Feature point sets among four face images are automatically corresponded by using Epipolar Plane Images (EPIs). The users can establish eye contact by acquiring the front face view, and moreover, they also can obtain various views of the image because 3D points of the object can be extracted from EPIs. Through these facilities, the proposed system will provide users with better communication than previous systems. In this paper, we describe the concept, implementation and the evaluation are described in various perspective.

Para ello se analiza, por un lado, la relación entre la Animación Sociocultural como práctica educativa y la Didáctica como disciplina centrada en el estudio de los procesos de enseñanza-aprendizaje. Este análisis se realiza desde una perspectiva de complementariedad entendiendo la Didáctica como un marco referencial para la Animación Sociocultural y, a su vez, planteando la Animación Sociocultural como un campo que amplía los espacios de acción, reflexión e investigación de la Didáctica. Por otro lado, el apartado final del artículo se centra de manera específica en la perspectiva del Curriculum y su relación con la Animación Sociocultural. Se analizan, sobre todo, aquellas teorías que conciben la práctica del Curriculum como un proceso de investigación y, de manera más específica, aquellas que expresan una visión crítica del mismo puesto que constituyen la concepción del Curriculum en la que mejor se acomoda la Animación Sociocultural desde los planteamientos que de este concepto se realizan a lo largo del artículo.ABSTRACT: The principal objective of this article is to establish some reflections on the processes of Socio-cultural Animation («Community education» in Anglo- Saxon contexts from a didactic perspective. Thus, in one part, we analyze the relationship between Socio-cultural Animation as an educational practice and Didactics as a discipline centered on the study of teaching-learning processes. This analysis is carried out from a complementary perspective, if we understand Didactics as a referential framework for Socio-cultural Animation and, in turn, establish Sociocultural Animation as a field that extends the areas of action, reflection, and investigation of Didactics. Then, the final part of the article centers specifically on the perspective of the Curriculum and its relationship with Socio-cultural Animation. Primarily, those theories that consider Curriculum development to be a process of investigation are analyzed, and, more specifically, those that express a critical vision of this. These theories constitute the conception of the Curriculum which best accommodates the idea of Socio-cultural Animation defended throughout the article.RÉSUMÉ: Le principal objectif de cet article est d'exposer quelques observations sur les processus d'Animation Socioculturelle dans une perspective didactique. Pour cela on analyse, d'une part, la relation entre l'Animation Socioculturelle comme pratique éducative et la Didactique comme discipline centrée sur l'étude des processus d'enseignement-apprentissage. Cette analyse est réalisée dans une perspective de complémentarité, la Didactique étant considérée comme un cadre de référence pour l'Animation Socioculturelle et l'Animation Socioculturelle étant considérée à son tour comme un domaine qui élargit les espaces d'action, de réflexion et de recherche de la Didactique. D'autre part, le dernier alinéa de l'article se centre plus spécifiquement sur la perspective du Curriculum et sa relation avec l'Animation Socioculturelle. Il analyse, surtout, les théories qui conçoivent la pratique du Curriculum comme processus de recherche et, plus particulièrement, les théories qui expriment une vision critique de ce dernier puisqu'elles offrent une conception du Curriculum qui permet à l'Animation Socioculturelle de s'adapter au mieux selon les observations réalisées sur ce concept tout au long de l'article.

Theft of stored credit card information is an increasing threat to e-commerce. We propose a dynamic virtual credit card number scheme that reduces the damage caused by stolen credit card numbers. A user can use an existing credit card account to generate multiple virtual credit card numbers that are either usable for a single transaction or are tied with a particular merchant. We call the scheme dynamic because the virtual credit card numbers can be generated without online contact with the credit card issuers. These numbers can be processed without changing any of the infrastructure currently in place; the only changes will be at the end points, namely, the card users and the card issuers. We analyze the security requirements for dynamic virtual credit card numbers, discuss the design space, propose a scheme using HMAC, and prove its security under the assumption the underlying function is a PRF.

In a US population of adult male and female Sikh immigrant participants (N = 350), we explored sociocultural factors related to depression, giving participants a choice between English or Punjabi surveys. Language preference pointed to a subgroup with higher levels of depression and lower satisfaction with life. Underreporting of depression suggests a general reluctance to discuss depression. While multiple sociocultural variables were associated with depression bivariably, multivariate analysis identified negative religious coping and anxiety as unique predictors of depression. Community interventions should tap into the protective close-knit social fabric of this community as an opportunity to change the stigma of mental health. PMID:26605953

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.
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

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

Full Text Available Until recently, it was believed that to learn/teach another language, it is sufficient for a person to know the grammar of another language in detail, have a good command of its vocabulary, and be able to pronounce the words, phrases and sentences well. However, later it turned out not to be so easy since more important issues were discovered which made the learning/teaching of another language (SL/FL more challenging than what it was previously thought. These issues are the social and the cultural aspects of L2/FL, the combination of which makes the sociocultural aspects of language learning and teaching. This means that, the circumstances under which we live, together with the symbols, symbolic tools, and signs we use to mediate and regulate our relationships with others, and with ourselves which make sociocultural theory are important issues for learning L2/FL. Later, the three generations of psycholinguistics are provided, the third generation of which is sociocultural theory together with the important notions of each generation. Finally, three educational implications of sociocultural theory are provided.

Comparative morphology, dealing with the diversity of form and shape, and functional morphology, the study of the relationship between the structure and the function of an organism's parts, are both important subdisciplines in biological research. Virtual anthropology (VA) contributes to comparative morphology by taking advantage of technological innovations, and it also offers new opportunities for functional analyses. It exploits digital technologies and pools experts from different domains such as anthropology, primatology, medicine, paleontology, mathematics, statistics, computer science, and engineering. VA as a technical term was coined in the late 1990s from the perspective of anthropologists with the intent of being mostly applied to biological questions concerning recent and fossil hominoids. More generally, however, there are advanced methods to study shape and size or to manipulate data digitally suitable for application to all kinds of primates, mammals, other vertebrates, and invertebrates or to issues regarding plants, tools, or other objects. In this sense, we could also call the field "virtual morphology." The approach yields permanently available virtual copies of specimens and data that comprehensively quantify geometry, including previously neglected anatomical regions. It applies advanced statistical methods, supports the reconstruction of specimens based on reproducible manipulations, and promotes the acquisition of larger samples by data sharing via electronic archives. Finally, it can help identify new, hidden traits, which is particularly important in paleoanthropology, where the scarcity of material demands extracting information from fragmentary remains. This contribution presents a current view of the six main work steps of VA: digitize, expose, compare, reconstruct, materialize, and share. The VA machinery has also been successfully used in biomechanical studies which simulate the stress and strains appearing in structures. Although methodological issues remain to be solved before results from the two domains can be fully integrated, the various overlaps and cross-fertilizations suggest the widespread appearance of a "virtual functional morphology" in the near future.

This report presents a novel concept of force control, called virtual force control. The virtual force concept avoids sudden step transition of position control to contact force control resulting in contact force disturbance when a robot end-effector makes contact with the environment. A virtual force/position control scheme consists of two loops: the force control loop and the position control loop. While the position control loop regulates the free motion, the force control loop regulates the contact force after making contact with the environment and the virtual force measured by a range sensor called capaciflector in the virtual environment. After presenting the concept of virtual force control, the report introduces a centering scheme in which the virtual force controller is employed to measure three points on a cone so that its center can be located. Experimental results of a one-degree-of-freedom virtual force control scheme applied in berthing an orbital replaceable unit are reported and compared with those of conventional pure contact force control cases.

This article briefly summarizes central components of theories of sexual development and outlines that these components depend largely on socio-cultural factors. A cultural change of human sexuality is reflected by several phenomena such as the public debate about sexual violence and its consequences, a diminuation of gender differences and a turn away from monosexuality, tremendous changes within the world of partner relationships and a mediatization of sexuality. This mediatization is paralleled by a public sexualization as well as a de-sexualization of the private sphere together with an increase of a loss of sexual desire reflecting well-known problems of human sexuality. Finally, it has to be stated that sexuality has experienced a demystification as a consequence of socio-cultural changes following the sexual liberalization. PMID:17177103

Among 300 Jewish sojourner youth (age range: 15-18 years) from the Russian Federation, the authors investigated associations of acculturation attitudes, measures of sociocultural adjustment, and length of the encounter with the host society, Israel. All the youth were participating in a 1-3-year program of high school studies in Israel. In the light of J. W. Berry's (1997) acculturation model, the authors examined the assumptions that the participants' adjustment to Israeli society would require readiness to abandon some of their previous identity and to adopt elements of a new identity characteristic of the host society. Lower degrees of separation and higher degrees of integration were positively linked with measures of sociocultural adjustment. The adjustment scores tended to decrease over time spent in Israel.

Full Text Available 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 their original culture but avoid or cannot have interact

Assembly operations require high speed and precision with low cost. The manufacturing industry has recently turned attenuation to the possibility of investigating assembly procedures using graphical display of CAD parts. For these tasks, some sort of feedback to the person is invaluable in providing a real sense of interaction with virtual parts. This research develops the use of a commercial assembly robot as the haptic display in such tasks. For demonstration, a peg-hole insertion task is studied. Kane's Method is employed to derive the dynamics of the peg and the contact motions between the peg and the hole. A handle modeled as a cylindrical peg is attached to the end effector of a PUMA 560 robotic arm. The arm is handle modeled as a cylindrical peg is attached to the end effector of a PUMA 560 robotic arm. The arm is equipped with a six axis force/torque transducer. The use grabs the handle and the user-applied forces are recorded. A 300 MHz Pentium computer is used to simulate the dynamics of the virtual peg and its interactions as it is inserted in the virtual hole. The computed torque control is then employed to exert the full dynamics of the task to the user hand. Visual feedback is also incorporated to help the user in the process of inserting the peg into the hole. Experimental results are presented to show several contact configurations for this virtually simulated task.

Habituation is the term used to describe acceptance by wild animals of a human observer as a neutral element in their environment. Among primates, the process takes from a few days for Galago spp. to several years for African apes. There are also intraspecies differences reflecting differences in habitat, home range, and ape-human relationship history. Here, we present the first study of the process of bonobo habituation in a fragmented habitat, a forest-savanna mosaic in the community-based conservation area led by the Congolese nongovernmental organization Mbou-Mon-Tour, Democratic Republic of the Congo. In this area, local people use the forest almost every day for traditional activities but avoid bonobos because of a traditional taboo. Because very few flight reactions were observed during habituation, we focused on quantitative parameters to assess the development of ape tolerance and of the tracking efficiency of observer teams. During the 18-month study period (May 2012-October 2013), 4043 h (319 days) were spent in the forest and bonobos were observed for a total of 405 h (196 contacts on 134 days). The average contact duration was stable over time (124 min), but the minimal distance during a contact decreased with habituation effort. Moreover, bonobo location and tracking efficiency, daily ratio of contact time to habituation effort, and the number of observations at ground level were positively correlated with habituation effort. Our observations suggest that bonobos become habituated relatively rapidly. These results are discussed in relation to the habitat type, ape species, and the local sociocultural context of villagers. The habituation process involves changes in ape behavior toward observers and also more complex interactions concerning the ecosystem, including the building of an efficient local team. Before starting a habituation process, knowledge of the human sociocultural context is essential to assess the balance between risks and benefits. PMID:26159325

Virtual screening of virtual libraries (VSVL) is a rapidly changing area of research. Great efforts are being made to produce better algorithms, selection methods and infrastructure. Yet, the number of successful examples in the literature is not impressive, although the quality of work certainly is high. Why is this? One reason is that these methods tend to be applied at the lead generation stage and therefore there is a large lead-time before successful examples appear in the literature. However, any computational chemist would confirm that these methods are successful and there exists a glut of start-up companies specialising in virtual screening. Moreover, the scientific community would not be focussing so much attention on this area if it were not yielding results. Even so, the paucity of literature data is certainly a hindrance to the development of better methods. The VSVL process is unique within the discovery process, in that it is the only method that can screen the > 10(30) genuinely novel molecules out there. Already, some VSVL methods are evaluating 10(13) compounds, a capacity that high throughput screening can only dream of. There is a huge potential advantage for the company that develops efficient and effective methods, for lead generation, lead hopping and optimization of both potency and ADME properties. To do this, it requires more than the software, it requires confidence to exploit the methodology, to commit synthesis on the basis of it, and to build this approach into the medicinal chemistry strategy. It is a fact that these tools remain quite daunting for the majority of scientists working at the bench. The routine use of these methods is not simply a matter of education and training. Integration of these methods into accessible and robust end user software, without dilution of the science, must be a priority. We have reached a coincidence, where several technologies have the required level of maturity predictive computational chemistry methods, algorithms that manage the combinatorial explosion, high throughput crystallography and ADME measurements and the massive increase in computational horsepower from distributed computing. The author is confident that the synergy of these technologies will bring great benefit to the industry, with more efficient production of higher quality clinical candidates. The future is bright. The future is virtual! PMID:12774691

In the present paper, we introduce a new control architecture aimed at driving virtual humans in interaction with virtual environments, by motion capture. It brings decoupling of functionalities, and also of stability thanks to passivity. We show projections can break passivity, and thus must be used carefully. Our control scheme enables task space and internal control, contact, and joint limits management. Thanks to passivity, it can be easily extended. Besides, we introduce a new tool as for manikin's control, which makes it able to build passive projections, so as to guide the virtual manikin when sharp movements are needed.

This essay introduces the opportunity for theory development and even empirical research on some aspects of astrosociology through today's online virtual worlds. The examples covered present life on other planets or in space itself, in a manner that can be experienced by the user and where the user's reactions may simulate to some degree future human behavior in real extraterrestrial environments: Tabula Rasa, Anarchy Online, Entropia Universe, EVE Online, StarCraft and World of Warcraft. Ethnographic exploration of these computerized environments raises many questions about the social science both of space exploration and of direct contact with extraterrestrials. The views expressed in this essay do not necessarily represent the views of the National Science Foundation or the United States.

Full Text Available The article shows the distinctive features of biological and cognitive approaches to the study of the origin and evolution of language. Their advantages in understanding and explaining of the individual foundations of language faculty are considered. The study shows that these approaches do not take into account the socio-cultural and supra-individual nature of language and its close evolutionary and functional relation with communication in nature and society. The paper argues that the aim of many researchers to find specific genes of language or special cognitive linguistic modules are achievable only in part due to systems and social nature of language, which cannot be reduced to any individual innate or acquired abilities. Nevertheless, biological and cognitive foundations should not be excluded from the system analysis of the language and have to be studied in their integrity with other sign systems (mathematic, expressive means of art, writing system, non-verbal communication, etc.. The article also discusses new insights into the theory of evolution and their applicability to the study of the origin and development of language (in particular, the problem of gradualistic/abrupt emergence of language. It is argued that the question of the "abrupt", "punctuated" evolution of language cannot be "Darwin's problem", as a number of modern scholars believe. As an alternative to the evolution of language on the basis of "macromutations" it is offered the concept of socio-cultural evolution model based on an understanding of language as a supra-individual, sociocultural sign system that develops due to the cumulative nature of culture and plasticity of individual development

Full Text Available This study aimed to analyze the attitude of college students regarding to interpersonal influence in virtual social networks related to consume decisions. It was conducted a survey with 200 college students from an Institution of Higher Education located in Santa Maria/RS. The sample was obtained through voluntary adhesion and the data collection instrument was applied in a virtual environment. Scales were adapted to measure and evaluate the propensity of students to influence and be influenced by their virtual contacts. The results suggest that the scales adapted are satisfactory to measure what they intend to do. The study also found that men are more able to influence the opinions of their virtual social contacts. On the other hand, the time dedicated to access the Internet positively and significantly influences the propensity of users to be influenced by their virtual social contacts. The correlation between the ability to influence the propensity to be influenced is significant and positive.

A detection process, contact recognition process, classification process, and identification process are applied to raw sensor data to produce an identified contact record set containing one or more identified contact records. A prioritization process is applied to the identified contact record set to assign a contact priority to each contact record in the identified contact record set. Data are removed from the contact records in the identified contact record set based on the contact priorities assigned to those contact records. A first contact stream is produced from the resulting contact records. The first contact stream is streamed in a contact transport stream. The contact transport stream may include and stream additional contact streams. The contact transport stream may be varied dynamically over time based on parameters such as available bandwidth, contact priority, presence/absence of contacts, system state, and configuration parameters.

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 Vygotskys 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 educations 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.

Full Text Available Para favorecer una alimentación correcta la orientación alimentaria debe considerar factores socioculturales que condicionen patrones y preferencias del consumo de alimentos propios de cada población. El objetivo de esta investigación fue describir el contexto sociocultural del embarazo y su alimentación en el ámbito doméstico, mediante un enfoque cualitativo. Se realizaron entrevistas en profundidad a 6 mujeres con embarazo de alto riesgo bajo la técnica de saturación de la información. Las entrevistas se transcribieron y analizaron de acuerdo a Bardín con ayuda del programa Atlas TI. Se identificó: incertidumbre por el embarazo no planeado y poco apoyo de la pareja; ciertos cambios en la alimentación para mejorar la salud; percepción de una mala y buena alimentación, aunque ésta no cumplía con las características de una dieta correcta; omisión de la cena y del grupo de verduras y frutas. Las encargadas de preparar y servir los alimentos no siempre fueron las mujeres embarazadas; los alimentos percibidos peligrosos fueron consumidos y los benéficos presentaron consumo escaso. Resaltó la necesidad de capacitar a los profesionales de la salud para considerar al contexto sociocultural en la orientación alimentaria que proporcionen.
Full Text Available Despierta gran interés teórico y social en nuestros días la identificación y medida de los factores que contribuyen al desarrollo de alteraciones de la imagen corporal y más concretamente al desarrollo de la insatisfacción corporal. El prototipo femenino de belleza dominante desde hace tres décadas en nuestra cultura propone una delgadez tan extrema que resulta no sólo inalcanzable, sino además muy poco saludable. El ideal masculino de belleza, por otro lado, demanda un cuerpo delgado, pero musculado, y éste ha adquirido gran importancia, por lo que con frecuencia se adoptan, a fin de mejorar la propia imagen, numerosas conductas peligrosas para la salud, como el consumo de esteroides, efedrina y dietas alimentarias dañinas. La imagen corporal, conformada por las autopercepciones físicas de cada persona, ha sido objeto de numerosas investigaciones durante las últimas décadas en relación con rasgos psicológicos tan importantes como la autoestima, la depresión, la ansiedad o los trastornos alimentarios y, muy en especial, con la insatisfacción corporal. Está comprobado que, en general, las mujeres manifiestan mayor insatisfacción corporal que los hombres en todas las épocas de su vida, desde la preadolescencia hasta la tercera edad, si bien las diferencias de sexo en la edad adulta y en la tercera edad son menores que en la adolescencia. Por otro lado, aun cuando la insatisfacción de las mujeres con su cuerpo tiende a mantenerse estable a lo largo de todo el ciclo vital, es digno de señalar que la importancia conferida a la apariencia física y, más en concreto, al tamaño y peso corporal, decrece con la edad. La presión sociocultural percibida aparece como principal causa de la insatisfacción corporal. Desde el enfoque sociocultural se señala, en concreto, a los medios masivos de comunicación, al entorno social próximo y a la familia como los tres elementos clave de dicha presión: cuanto más altos son los niveles de presión percibida con respecto a una imagen corporal idealizada, más se incrementa la preocupación por la imagen y por las estrategias de cambio corporal. La investigación previa ha prestado considerable atención a las diferencias de sexo y de edad en cuanto a la insatisfacción corporal, pero se echan en falta: a conocimientos más precisos sobre la insatisfacción corporal de los hombres; b una perspectiva comparativa de las diferencias de sexo tanto en insatisfacción corporal como en presión percibida a lo largo de las distintas etapas del ciclo vital; c mayor información sobre las variaciones interpersonales en la relación entre la insatisfacción corporal y la presión sociocultural percibida, y d una mejor comprensión de la naturaleza de las influencias socioculturales. Esta investigación trata de contribuir a la superación de estas carencias planteándose las siguientes hipótesis: 1 La insatisfacción corporal guarda estrecha relación con la presión sociocultural percibida; 2 las mujeres participantes, en todos los grupos de edad, muestran más insatisfacción corporal e indican sentirse más influidas por factores socioculturales que los hombres; 3 las diferencias de sexo (tanto en insatisfacción corporal como en presión sociocultural percibida son mayores en los grupos de menor edad que en los de más edad; 4 el sexo resulta ser un mejor predictor de la insatisfacción corporal y de los influjos socioculturales percibidos que la edad. Participaron en el estudio 1259 personas: 627 adolescentes, 271 adultos jóvenes, 248 adultos y 112 sujetos mayores de 55 años, quienes respondieron el Eating Disorders Inventory-2 (EDI-2, de Garner, que permite identificar la insatisfacción corporal, así como el Cuestionario de Influencias sobre el Modelo Estético Corporal (CIMEC, de Toro, Salamero y Martínez-Mallén...

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).

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

Full Text Available This research started from the need of looking for ways to involve learners dynamically in classroom activities, including social issues. The study was developed with ten students (10 in tenth grade. It was carried out to explore tenth graders perceptions on gender, race and social class to report their socio-cultural stereotypes through the development of a project work called Stereotyping our Culture divided into three (3 workshops, where students dealt with different Colombian social issues while they were learning English. Data collection sources incorporated field notes to record events and ideas for further reflection, video-taping to get accurate students perceptions to confirm our impressions reported in the field notes and artifacts from workshops to perceive what students wanted to express by means of drawings or writings.

Full Text Available Las características de una familia representan más que la suma de las personalidades individua-les, y para entender su dinámica es necesario explorar la manera en que las mismas se relacionanentre sí. Por tanto, el objetivo de esta investigación fue analizar la dinámica familiar de jóvenesuniversitarios considerando las esferas de formación de identidad y la integración sociocultural.Se aplicó a una muestra de 566 alumnos universitarios un cuestionario que mide la dinámicafamiliar. Entre los resultados se encontró que, si bien la formación de la identidad era adecua-da, hay algunos indicadores de que los padres no habían independizado a sus hijos. Si bien laintegración social fue alta en la formación de sentimientos de solidaridad social, no lo fue en lasrelaciones de amistad y en el apego a la identidad cultural. Se discuten las implicaciones para eldesarrollo personal, escolar y social de los estudiantes.
Full Text Available A paradigm can be thought of as a living commodity system, carried by a self-organising group. The commodity is often "practical knowledge", and the paradigm maintains a life cycle that begins with commodity gestation, leading to commodity depreciation through death or transformation. During its 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.
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.
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.

In the present study, heterosexual college women (N=327) and men (N=160) were asked about their body type preferences for (hypothetical) romantic partners. Participants chose a particular silhouette value as ideal for a romantic partner, and rated how important it was to them for their partner to have this ideal body type. Men placed more importance on the body silhouette they chose for a partner than women did, and men's importance ratings were positively associated with the rated sexual permissiveness of their peer group and their total media use. Consuming sports media and watching reality television were the best media predictors of men's judgments about women's bodies. Less variability was explained in women's preferences for men partners' bodies, but endorsing adversarial sexual attitudes was positively related to judging the ideals chosen for men's bodies as important. Results were interpreted within both evolutionary and sociocultural theoretical frameworks. PMID:25462878

Full Text Available This paper reports the results of a study of the Kazakh kinship structure, classification and the socio-cultural functions of the Kazakh kinship terms. The Kazakhs have developed at first glance very complex and many branched kinship bonds with the moral codes, family relationship etiquette, the patterns of rights , duties and responsibilities thus being one of the strongest binding forces. The first and foremost principle of the Kazakh kinship system is the principle of the seven ancestors-a particular kind of chain of parent-child links between ancestors and descendants. The principle of 7 ancestors defines marriage rules, sex regulation, and incest taboo. For Kazakhs kinship was one of the strongest survival strategies thanks to which they could save integrity of their country. Every terminologically identified kinship category is associated with a culturally distinctive pattern of behavior which should be followed in relation to EGO.

En esa prenda, elaborada a partir de una pieza de tela de algodón rectangular, decorada con un bordado alrededor del escote y en la orilla inferior, el diseño y los colores de las flores, hojas, animales, ramas y grecas, constituyen un lenguaje particular que trasciende el juicio estético y adquiere, en su contexto sociocultural, diversos significados para quien lo porta y para quien lo mira. Abstract in english Every discourse has an aesthetic dimension as well as a particular composition that varies according to the discursive type, which can be analyzed from an interdisciplinary perspective. This work focuses on the visual discourse of a traditional Mayan dress, made and worn by women of the Yucatan Peni [...] nsula, and known in Spanish as the "hipil." Fabricated from cotton cloth and embroidered around the neckline and the bottom edge with different motifs such as flowers, leaves, animals, branches and frets, the complex interlacing of images constitutes a particular code that holds different meanings for the wearer and the viewer. In this study I will analyze the garments that are worn in the sociocultural context of Los Chenes (Campeche).

The emergence of off-screen interaction devices is bringing the field of virtual reality to a broad range of applications where virtual objects can be manipulated without the use of traditional peripherals. However, to facilitate object interaction, other stimuli such as haptic feedback are necessary to improve the user experience. To enable the identification of virtual 3D objects without visual feedback, a haptic display based on a vibrotactile glove and multiple points of contact gives users an enhanced sensation of touching a virtual object with their hands. Experimental results demonstrate the capacity of this technology in practical applications. PMID:25137722

Virtual classes are class-valued attributes of objects. Like virtual methods, virtual classes are defined in an object's class and may be redefined within subclasses. They resemble inner classes, which are also defined within a class, but virtual classes are accessed through object instances, not...... as static components of a class. When used as types, virtual classes depend upon object identity - each object instance introduces a new family of virtual class types. Virtual classes support large scale program composition techniques, including higher-order hierarchies and family polymorphism. The...... original definition of virtual classes in BETA left open the question of static type safety, since some type errors were not caught until runtime. Later the languages Caesar and gbeta have used a more strict static analysis in order to ensure static type safety. However, the existence of a sound...

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

This article describes a virtual technique for transferring the location of a digitized cast from the patient to a virtual articulator (virtual facebow transfer). Using a virtual procedure, the maxillary digital cast is transferred to a virtual articulator by means of reverse engineering devices. The following devices necessary to carry out this protocol are available in many contemporary practices: an intraoral scanner, a digital camera, and specific software. Results prove the viability of integrating different tools and software and of completely integrating this procedure into a dental digital workflow. PMID:26372628

Full Text Available The paper deals with the interrelations between society, education and culture. Using the comparative analysis of classical approaches to defining the above spheres, the author comes to conclusion that the nature of socio-cultural processes can be explored and described most consistently by applying comprehensive models of the post-non-classical science and considering civilization, education and culture in the context of the unified dynamic flow of socio-cultural genesis. The research investigates the dialectics of socio-cultural processes in the light of systematic synergetic approach, the advancing role of education in socio-cultural dynamics being revealed and substantiated. The author emphasizes its inevitably rising priority due to sustained development of civilization bringing about the new environmentally-oriented meta-culture.The obtained results can be used in pedagogic research methodology, designing and modeling the educational process, its content, technology and organization.

This study determined how sociocultural messages to change one's body are perceived by adolescents from different cultural groups. In total, 4904 adolescents, including Australian, Chilean, Chinese, Indo-Fijian, Indigenous Fijian, Greek, Malaysian, Chinese Malaysian, Tongans in New Zealand, and Tongans in Tonga, were surveyed about messages from family, peers, and the media to lose weight, gain weight, and increase muscles. Groups were best differentiated by family pressure to gain weight. Girls were more likely to receive the messages from multiple sociocultural sources whereas boys were more likely to receive the messages from the family. Some participants in a cultural group indicated higher, and others lower, levels of these sociocultural messages. These findings highlight the differences in sociocultural messages across cultural groups, but also that adolescents receive contrasting messages within a cultural group. These results demonstrate the difficulty in representing a particular message as being characteristic of each cultural group. PMID:25497878

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

Developments in digital interaction technologies provide new interdisciplinary fields for creative work at the intersection of design, art and technology. These technologies also present new possibilities to integrate physical spaces with interactive layers of digital information for multi-user interaction, customization and interdisciplinary collaboration. These spaces accommodate new forms of spatial and social practices, provide multimodal communication resources in physical and virtual environments, and allow individuals (or groups) to actively engage with collaborative creative experiences. The three-dimensional representation of space and the resources for non-verbal communication enable the users to interact with the digital content in more complex yet engaging ways. However, understanding the communicative resources in virtual spaces with the theoretical tools that are conventionally used to describe physical spaces become problematic, especially when we consider the affordances and constraints for mediating spatial practices with digital tools. This article proposes a multimodal social semiotic approach to the design of interactive virtual environments and virtually augmented physical spaces as new forms of technologically mediated collaborative spaces. It presents the findings of multiple case studies conducted by different 3D virtual environment technologies and interaction contexts, including screen-based virtual worlds and virtually- augmented physical spaces. The multimodal analytical perspective particularly emphasizes the role of audio-visual resources in co-creating representations for effective collaboration, and the socio-cultural factors in construction of meaningful virtual environments.

Full Text Available Según la última Encuesta de Hábitos Deportivos (2010, el running es la quinta actividad físico-deportiva más practicada por los españoles: un 5,6?% de la población mayor de quince años afirma practicarla con regularidad. Los practicantes del running, sin embargo, están lejos de poder ser considerados como un grupo homogéneo. En esta comunicación se presenta un modelo de clasificación sociocultural de los practicantes de running, obtenido a partir de los resultados de una investigación cualitativa realizada con una muestra de 76 corredores populares. La investigación parte de una adaptación del modelo cultural de Douglas (1996 y el modelo de clasificación de las actividades de ocio de Elias y Dunning (1988 según los cuales las dos dimensiones que estructuran el campo social serían las presiones grupales y estructurales. Las primeras se manifiestan de un modo directo en el carácter relacional de esta práctica deportiva (individual versus grupal, mientras las segundas se refieren a su grado de formalización técnica, que se concretaría en aspectos como el establecimiento de objetivos de mejora, el grado de adhesión a planes de entrenamiento o el control del rendimiento (disciplina versus espontaneidad. La intersección de estas dos dimensiones descubre la existencia de cuatro perfiles o tipos ideales de corredores: los solitarios hedonistas, los individualistas competitivos, los rodadores sociables y los grupalistas disciplinados, cuyas características son examinadas en este trabajo.

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.

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

We review Giroux's contact handles and contact handle attachments in dimension three and show that a bypass attachment consists of a pair of contact 1 and 2-handles. As an application we describe explicit contact handle decompositions of infinitely many pairwise non-isotopic overtwisted 3-spheres. We also give an alternative proof of the fact that every compact contact 3-manifold (closed or with convex boundary) admits a contact handle decomposition, which is a result originally due to Giroux.

Network virtualization can offer more flexibility and better manageability for the future Internet by allowing multiple heterogeneous virtual networks (VN) to coexist on a shared infrastructure provider (InP) network. A major challenge in this respect is the VN embedding problem that deals with the efficient mapping of virtual resources on InP network resources. Previous research focused on heuristic algorithms for the VN embedding problem assuming that the InP network remains operational at ...

Full Text Available Los profundos y acelerados cambios desencadenados en Cuba a partir de 1990, crearon condiciones favorables para un reavivamiento religioso que se ha comportado de forma diferente a lo largo de casi veinte años, en interacción con las complejidades socioeconómicas en lo nacional y global. No cabe dud [...] a que en situaciones de crisis donde prevalecen insatisfacciones, desorientaciones y sentimientos de desprotección se potencia lo religioso, acudiéndose a lo metasocial o sobrenatural como explicación, respaldo, esperanza, ayuda y respuesta ante lo desconocido. En el caso de nuestro país, lo religioso pasó a expresar y reflejar los impactos de los cambios otorgándoles nuevos significados desde la fe. El trabajo que aquí se presenta pretende un acercamiento a la interrelación entre las transformaciones sociales y dinámicas religiosas, tomando por marco el conjunto cultural social global dentro del cual se desarrollan. Abstract in english The deep and accelerated changes that took place in Cuba from the 1990 and onward created favorable conditions for a religious revitalization which, together with complex national and international factors have assumed extremely varied forms during the almost twenty years that have passed since then [...] . There is no doubt that in situations of crisis, where dissatisfaction, disorientation and a feeling of helplessness prevail, the religious factor gains force, and people increasingly seek explanation, support, hope, help and answers in the supernatural powers against the unknown. In the Cuban case, the religious factor came to express and reflect the impact of these changes, assigning them new significance anchored in the religious faith. The text that is presented here explores the interrelation between social transformations and religious dynamics, in the framework of the global socio-cultural context in which this process takes place.

As this comprehensive and multidisciplinary book makes clear, virtuality has a pedigree that pre-dates the computer age and modern virtual worlds, a pedigree that can be traced back to classical mythology and beyond. Equally, the concept of virtuality is not the province of one field of study alone but is the foundation and driving force of many, both theoretical and applied. Our conceptualizations and applications of virtuality are multiple, as contributors demonstrate across the nine sections of the book that move from philosophy to technologies and applications before returning to philosoph

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.

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

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.
To realize nanocarbons in general and carbon nanotube (CNT) in particular as on-chip interconnect materials, the contact resistance stemming from the metalCNT interface must be well understood and minimized. Understanding the complex mechanisms at the interface can lead to effective contact resistance reduction. In this study, we compile existing published results and understanding for two metalCNT contact geometries, sidewall or side contact and end contact, and address key performance characteristics which lead to low contact resistance. Side contacts typically result in contact resistances >1 k?, whereas end contacts, such as that for as-grown vertically aligned CNTs on a metal underlayer, can be substantially lower. The lower contact resistance for the latter is due largely to strong bonding between edge carbon atoms with atoms on the metal surface, while carrier transport across a side-contacted interface via tunneling is generally associated with high contact resistance. Analyses of high-resolution images of interface nanostructures for various metalCNT structures, along with their measured electrical characteristics, provide the necessary knowledge for continuous improvements of techniques to reduce contact resistance. Such contact engineering approach is described for both side and end-contacted structures. (paper)

Although recent studies have shown that the sociocultural characteristics which children in non-western society bring into the classroom from their environment create a wedge between what they are taught and what they learn, very little has been done to solve the problem. A learner who is not positively disposed to, or has a socio-cultural background that is indifferent to, learning science would find it hard to learn science effectively. This study investigated whether instruction through the use of the socio-cultural mode has any significant effect on students' attitude towards the learning of science. The sample consisted of 600 senior secondary year-one students (442 boys, 158 girls) from 15 secondary schools in Nigeria. The Socio-Cultural Environment Scale (SCES) and the Biology Achievement Test (BAT) were used to measure the change in attitude and achievement of subjects in a pretest-posttest situation after a six-week treatment. Evidence was found to support the hypothesis that science instruction which deliberately involves the discussion of socio-cultural views about science concepts engenders positive attitudes towards the study of science. The findings also indicate that anthropomorphic and mechanistic views can be presented in such a way as to promote positive attitudes towards the study of science in traditional cultures.

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.

Full Text Available The virtual recreation of a physical three dimensional (3D exhibition or museum allows a visitor to navigate in this virtual scenario in a way closer to reality. This issue is particularly relevant when the museum building is by itself a piece of art, as it is often the case. In this paper, the use of virtual 3-D models in the domain of cultural diffusion is analysed, considering the common aspects of its application either for collections of museums or for buildings and artifacts deteriorated or destroyed along the time. A wide range of applications are presented to exemplify the different requirements and techniques that can be considered in this domain. Techniques to create 3-D models are reviewed as they are the base to generate a virtual environment and special attention is given to applications devoted to the development of 3-D virtual museum exhibitions.

Many solutions have been proposed to raise the security level of virtualisation. However, most overlook the security of virtual disk images. With our paper we present a secure, flexible and transparent security architecture for virtual disk images. Virtual machines running on our architecture transparently benefit from confidentiality and integrity assurance. We achieve this by incorporating the concepts of Trusted Computing and in particular the Trusted Platform Module (TPM). This enables us to provide a secure and flexible trusted virtual disk infrastructure to a broad number of platforms. Furthermore, the unique concept of Trusted Virtual Disk Images (TVDI) allows an image owner to stay in control over the disk image throughout its complete life-cycle.

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

ATLAS software has been developed mostly on CERN linux cluster lxplus or on similar facilities at the experiment Tier 1 centers. The fast rise of virtualization technology has the potential to change this model, turning every laptop or desktop into an ATLAS analysis platform. In the context of the CernVM project we are developing a suite of tools and CernVM plug-in extensions to promote the use of virtualization for ATLAS analysis and software development. The Virtual Machine Logbook (VML), in particular, is an application to organize work of physicists on multiple projects, logging their progress, and speeding up ''context switches'' from one project to another. An important feature of VML is the ability to share with a single 'click' the status of a given project with other colleagues. VML builds upon the save and restore capabilities of mainstream virtualization software like VMware, and provides a technology-independent client interface to them. A lot of emphasis in the design and implementation has gone into optimizing the save and restore process to makepractical to store many VML entries on a typical laptop disk or to share a VML entry over the network. At the same time, taking advantage of CernVM's plugin capabilities, we are extending the CernVM platform to help increase the usability of ATLAS software. For example, we added the ability to start the ATLAS event display on any computer running CernVM simply by clicking a button in a web browser. We want to integrate seamlessly VML with CernVM unique file system design to distribute efficiently ATLAS software on every physicist computer. The CernVM File System (CVMFS) download files on-demand via HTTP, and cache it locally for future use. This reduces by one order of magnitude the download sizes, making practical for a developer to work with multiple software releases on a virtual machine.
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.

While sociocultural scholarship has attempted an ecological explanation of intimate partner violence, it has largely been criticized for ignoring dispositional factors of both perpetrators and victims. Dependent personality and attachment-related emotional problems have been implicated in the extant literature as major intrapsychic processes involved in the perpetration and victimization of partner abuse, particularly in Western societies. These studies largely rely on a cultural background of individualism as a social representation to explain the behaviour of both victims and perpetrators of dependency and attachment-related spousal violence as a form of a psychopathology. This article discusses partner dependency and jealousy-motivated spousal violence as socioculturally situated, dependent on contextual and relational conditions of meaning embedded in the communal society of Ghana. It highlights Ghanaian communal personality, gendered socialization and meaning systems of marriage as salient sociocultural features for conceptualizing partner dependency and emotional-related spousal violence.

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.

Till date we have not made Contact with any Extraterrestrial civilizations. The Fermi Paradox remains a paradox - the Great Silence prevails. In the light of the Rare Earth hypothesis, it seems that advanced life is exceedingly rare in the universe. Also, if there does exist some Extraterrestrial civilizations then still achieving Contact is extremely difficult as the very nature of the universe discourages Contact. It's as if there is a Cosmic Contact Censorship in place.
Chinas 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 Chinas 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 Chinas 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 mens sexual practices is important for responding to the newly emerging stage of Chinas HIV epidemic. PMID:18975228

In this note we show that $+1$-contact surgery on distinct Legendrian knots frequently produces contactomorphic manifolds. We also give examples where this happens for $-1$-contact surgery. As an amusing corollary we find overtwisted contact structures that contain a large number of distinct Legendrian knots with the same classical invariants and tight complements.

Fragrance components and preservatives are certainly the most frequently observed allergens; however, all ingredients must be considered when investigating for contact allergy.

In general electric field forces have the distinctive property of being able to mediate forces to virtually any material in a fully non-invasive and contact-free fashion. Based on this property, electrostatic levitation holds great promise for the semiconductor, solar panel, and flat-panel display industry since the handling of (semi)conducting and dielectric materials in a contact-free manner can bring many advantages and solve long-standing contamination and particulate control problems.

Full Text Available This article reports a study done with five English language teachers in Colombian rural areas. Questionnaires and interviews were used to see how these teachers understand their professional practice considering the contextual features of their regional workplaces. Amongst the findings, we noticed that these teachers have to mediate between local and global tensions and also deal with socio-cultural matches and mismatches in their labours. It is hoped this work raises awareness of critical socio-cultural factors involved in the teaching of English in rural settings and of the complexity of its intercultural dimension.

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, learners 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.

The need to remain competitive in the open market forces companies to concentrate on their core competencies while searching for alliances when additional skills or resources are needed to fulfill business opportunities. The changing business situation of companies and customer needs have motivated researchers to introduce Virtual Organization (VO) idea. A Virtual Organization is always a form of partnership and managing partners and handling partnerships are crucial. Virtual organizations are defined as a temporary collection of enterprises that cooperate and share resources, knowledge, and competencies to better respond to business opportunities. This paper presents base concepts of virtual organizations including properties, management concepts, operational concepts, and main issues in collaboration such as security and authentication.

Virtual links were introduced by Kauffman in 1999. We characterize the virtual link invariants that are partition functions of vertex models (as considered by de la Harpe and Jones), both in the real and in the complex case. We show that for any fixed number of states, these invariants form an affine variety. Basic techniques are the first and second fundamental theorem of invariant theory for the orthogonal group (in the sense of Weyl) and some related methods from algebrai...

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

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.

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.

Any knowledge environment aimed at virtual teams should promote identification, access, capture and retrieval of relevant knowledge anytime / anywhere, while nurturing the social activities that underpin the knowledge sharing and creation process. In fact, socio-cultural issues play a critical role in the successful implementation of Knowledge Management (KM), and constitute a milestone towards value creation. The findings indicate that Knowledge Management Systems (KMS) promote value creation when they embed and nurture the social conditions that bind and bond team members together. Furthermore, technology assets, human networks, social capital, intellectual capital, and change management are identified as essential ingredients that have the potential to ensure effective knowledge value creation.

Wait-time, a variable related to questioning in a teaching-learning situation, has been found to have implications for the inquiry mode of science teaching especially in Western classroom environments. Aside from the fact that the literature is very sparse in this area about what obtains in developing countries, nothing appears to be available with regard to how wait-time interacts with the sociocultural factors within non-Western science classrooms. In a non-Western country such as Nigeria where most science programs in schools are inquiry-oriented, do teachers take notice of, and effectively use, wait-time in the teaching-learning process? Are science teachers able to effectively use the mediating role of sociocultural factors in science teaching in a traditional environment which expects children to be seen only and not heard? The main purpose of this study was to investigate the wait-time of Nigerian integrated science teachers in relation to the amount of students' participation in inquiry. This study also investigated the relationship between wait-time and sociocultural attitudinal factors prevalent in traditional societies. The instruments used for data collection were the Hough's Observational Schedule and a modified version of the Socio-Cultural Environment Scale (SCES); a stop-watch was used to measure the wait-time of audio-recorded integrated science lessons of 37 integrated science teachers from selected junior secondary schools in Kaduna State, Nigeria. The results showed that the average wait-time TT and wait-time ST of the integrated science teachers was 3.0 seconds and 0.7 seconds, respectively. The study reported the amount of student participation in the student-teacher classroom discourse to be very low. Wait-time was also shown to have a strong relationship with sociocultural factors of authoritarianism, goal structure, societal expectation, and traditional worldview. The pedagogical and curricular implications of the results have been highlighted.

Full Text Available For scientists and service workers has always been an actual the problem of not simply informing recipients, such a material feed, forms and methods of work at which the formation and improvement of people's aesthetic consciousness happen. Tours in the museums in the world, real and virtual, will inevitably lead us to get acquainted with the work of the Surrealists and the problem of how to generate aesthetic consciousness of students so that their axiological scale has not been distorted, and the person clearly stresses the main moral values, separated the wheat from the chaff, and at the same time has a wide range of erudition, the conception of a wide variety phenomena of art.Some postulates of aesthetics of Romanticism are close in common with surrealism. For example, Novalis believed that only a poet through intuition can guess the meaning of life. The generality of the original aesthetic postulates of Romanticism and Surrealism is still very relative, in many aspects surface and does not capture their artistic concepts. In contrast to the romantic, artistic thought of Surrealists is illogical, random capricious associations and whimsical comparisons reign in it. Surrealism penetrated into many areas of our lives, and is associated with many activities, but for most people it is designed to meet the need for knowledge.The article shows that surrealism is interesting for artists and psychologists current that in the future has the perspectives for further development, but we must be wary of the ethical postulates of representatives of this trend.

Ultrasonography is a widespread diagnostic technique that can take advantage of virtual reality for the purpose of training and rehearsal. The placement, orientation and body interaction of the probe is fundamental for the execution of the exploration. This paper introduces a virtual reality setup that employs visuo-haptic feedback for virtual ultrasonography. The haptic feedback is provided by desktop delta-like haptic interface with a 3D printed ultrasonography probe, and features haptic point-cloud rendering with implicit surface rendering. The visual feedback is provided by a Head Mounted Display that displays the virtual body, the probe and the operator's hand while not in contact with the probe. The system provides a co-located experience by means of precise calibration of the reference system allowing to synchronize the display of the hand and the probe with the location of the corresponding physical entities.

Full Text Available Virtualized environments can make forensics investigation more difficult. Technological advances in virtualization tools essentially make removable media a PC that can be carried around in a pocket or around a neck. Running operating systems and applications this way leaves very little trace on the host system. This paper will explore all the newest methods for virtualized environments and the implications they have on the world of forensics. It will begin by describing and differentiating between software and hardware virtualization. It will then move on to explain the various methods used for server and desktop virtualization. Next, it will explain how virtualization affects the basic forensic process. Finally, it will describe the common methods to find virtualization artifacts and identify virtual activities that affect the examination process of certain virtualized user environments.
The promise of CT-based radiotherapy treatment design remains largely unfulfilled. There is clearly a variety of reasons for this including cost considerations and physicians' justifiable reluctance to alter standard practice but also, and perhaps most importantly, a broad failure of the community to integrate the CT scanner into the process of treatment design. We are addressing this issue by reshaping the treatment design process and the role of the CT scanner in that process in order to realize the benefit of the additional information the scanner makes available. In particular we believe that a superset of the functions of a conventional treatment simulator can be provided to an acceptable degree of fidelity by a CT scanner, appropriate computer displays, and Computer-Aided Design software. Because it involves the interaction of a virtual simulator (provided by the CAD software) with a virtual patient (defined by CT) we call this process virtual simulation. The primary objective of virtual simulation is to extend the treatment design options available to a radiotherapist, and to provide tools to facilitate rapid understanding and evaluation of those options, by reducing the treatment design process to an intuitive manipulation of simple pictures. We present here the key elements of the virtual simulation system and their relations to their traditional counterparts. We also discuss our prototype implementation of the CAD tool. 8 refs.; 1 figure; 1 table

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.

Interpreting the excesses around 750 GeV in the diphoton spectra to be the signal of a new heavy scalar decaying to photons, we point out the possibility of looking for correlated signals with virtual photons. In particular, we emphasize that the effective operator that generates the diphoton decay will also generate decays to two leptons and a photon, as well as to four leptons, independently of the new resonance couplings to $Z\\gamma$ and $ZZ$. Depending on the relative sizes of these effective couplings, we show that the virtual diphoton component can make up a sizable, and sometimes dominant, contribution to the total $2\\ell \\gamma$ and $4\\ell$ partial widths. We also discuss modifications to current experimental cuts in order to maximize the sensitivity to these virtual photon effects. Finally, we briefly comment on prospects for channels involving other Standard Model fermions as well as more exotic decay possibilities of the putative resonance.
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 dont 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.

Goldfarb, Steven; The ATLAS collaboration
ATLAS Virtual Visits is a project initiated in 2011 for the Education & Outreach program of the ATLAS Experiment at CERN. Its goal is to promote public appreciation of the LHC physics program and particle physics, in general, through direct dialogue between ATLAS physicists and remote audiences. A Virtual Visit is an IP-based videoconference, coupled with a public webcast and video recording, between ATLAS physicists and remote locations around the world, that typically include high school or university classrooms, Masterclasses, science fairs, or other special events, usually hosted by collaboration members. Over the past two years, more than 10,000 people, from all of the worldâs continents, have actively participated in ATLAS Virtual Visits, with many more enjoying the experience from the publicly available webcasts and recordings. We present an overview of our experience and discuss potential development for the future.

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

Intracranial aneurysms are the primary cause of non-traumatic subarachnoid hemorrhage. Morbidity and mortality remain high even with current endovascular intervention techniques. It is presently impossible to identify which aneurysms will grow and rupture, however hemodynamics are thought to play an important role in aneurysm development. With this in mind, we have simulated blood flow in laboratory animals using three dimensional computational fluid dynamics software. The data output from these simulations is three dimensional, complex and transient. Visualization of 3D flow structures with standard 2D display is cumbersome, and may be better performed using a virtual reality system. We are developing a VR-based system for visualization of the computed blood flow and stress fields. This paper presents the progress to date and future plans for our clinical VR-based intervention simulator. The ultimate goal is to develop a software system that will be able to accurately model an aneurysm detected on clinical angiography, visualize this model in virtual reality, predict its future behavior, and give insight into the type of treatment necessary. An associated database will give historical and outcome information on prior aneurysms (including dynamic, structural, and categorical data) that will be matched to any current case, and assist in treatment planning (e.g., natural history vs. treatment risk, surgical vs. endovascular treatment risks, cure prediction, complication rates).

Full Text Available 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 construtivista, 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.School failure consists of a persistent problem in our educational system. This paper aims at contributing to understand the issue by presenting and theoretically discussing empirical data concerning the dynamics of teacher-students interactions. We draw our analysis on a constructivist sociocultural theoretical framework, which stresses the interactions between sociocultural factors and human agency, claiming for the unison, intertwined nature of affect and cognition. 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.

In this article, we review current research activities in contact material development for electronic and nanoelectronic devices. A fundamental issue in contact materials research is to understand and control interfacial reactions and phenomena that modify the expected device performance. These reactions have become more challenging and more difficult to control as new materials have been introduced and as device sizes have entered the deep nanoscale. To provide an overview of this field of inquiry, this issue of MRS Bulletin includes articles on gate and contact materials for Si-based devices, junction contact materials for Si-based devices, and contact materials for alternate channel substrates (Ge and III-V), nanodevices.

To reduce plant down time during irradiated fuel cell dismantling at Torness Power Station, a new visualisation technique has been used for the manipulator. Complex computer graphics packages were used to provide a ``Virtual Reality`` environment which allowed the Irradiated Fuel Dismantling Cell to be simulated. Significant cost savings have been achieved due to reductions in lost output. The virtual reality environment is at present being extended to the design and deployment of a new manipulator for in-vessel inspection of the boiler. (UK).

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.

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.

âVirtual water,â water needed for crop production, is now being mainstreamed in the water policy world. Relying on virtual water in the form of food imports is increasingly recommended as good policy for water-scarce areas. Virtual water globalizes discussions on water scarcity, ecological sustainability, food security and consumption. Presently the concept is creating much noise in the water and food policy world, which contributes to its politicization. We will argue that the virtual water ...

Two experiments investigated the effects of haptic, auditory and graphic contact cues on reaching to grasp augmented objects (physical and graphic) and virtual objects (graphic only) of various sizes. In Experiment 1, auditory contact cues were presented either to enhance or to replace natural haptic contact cues in grasping. In Experiment 2, graphic contact cues were presented alone or in combination with auditory cues, and were provided either to enhance or to replace haptic contact information. Visual information of the hand was not available. Experiment 1 showed that enhancing haptic contact information with redundant auditory cues (augmented object) led to faster movement times than haptic cues alone. When haptic information was not available (virtual object), it could be replaced to some extent by auditory contact cues. In Experiment 2 movement times were fastest when both auditory and graphic cues were provided, and slowest when no contact cues were provided. Further, movement times were scaled to target width when reaching to grasp augmented objects, thus following Fitts' law. In contrast, movement times showed a less pronounced decrease with increasing object size for virtual objects. However, even in the absence of haptic information, movement times showed a more pronounced scaling to object size when auditory contact cues were provided. These results emphasize the importance of contact information, especially haptic and auditory information, for planning and control of reaching and grasping. PMID:17242914

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.

The attractions of virtual computing are many: reduced costs, reduced resources and simplified maintenance. Any one of these would be compelling for a medical imaging professional attempting to support a complex practice on limited resources in an era of ever tightened reimbursement. In particular, the ability to run multiple operating systems optimized for different tasks (computational image processing on Linux versus office tasks on Microsoft operating systems) on a single physical machine is compelling. However, there are also potential drawbacks. High performance requirements need to be carefully considered if they are to be executed in an environment where the running software has to execute through multiple layers of device drivers before reaching the real disk or network interface. Our lab has attempted to gain insight into the impact of virtualization on performance by benchmarking the following metrics on both physical and virtual platforms: local memory and disk bandwidth, network bandwidth, and integer and floating point performance. The virtual performance metrics are compared to baseline performance on "bare metal." The results are complex, and indeed somewhat surprising. PMID:21207096

Contact mechanics has its application in many engineering problems. No one can walk without frictional contact, and no car would move for the same r- son. Hence contact mechanics has, from an engineering point of view, a long history, beginning in ancient Egypt with the movement of large stone blocks, over ?rst experimental contributions from leading scientists like Leonardo da Vinci andCoulomb, to today's computational methods. In the past c- tact conditions were often modelled in engineering analysis by more simple boundary conditions since analytical solutions were not present for real worl

The strength of the bond between optically contacted quartz surfaces was investigated. The Gravity Probe-B (GP-B) experiment to test the theories of general relativity requires extremely precise measurements. The quartz components of the instruments to make these measurements must be held together in a very stable unit. Optical contacting is suggested as a possible method of joining these components. The fundamental forces involved in optical contacting are reviewed and relates calculations of these forces to the results obtained in experiments.

We present the concept, optical design, and first proof of principle experimental results for a telescopic contact lens intended to become a visual aid for age-related macular degeneration (AMD), providing magnification to the user without surgery or external head-mounted optics. Our contact lens optical system can provide a combination of telescopic and non-magnified vision through two independent optical paths through the contact lens. The magnified optical path incorporates a telescopic arrangement of positive and negative annular concentric reflectors to achieve 2.8x - 3x magnification on the eye, while light passing through a central clear aperture provides unmagnified vision.

In this paper, a virtual experiment concerning driving on off-roads is investigated via 3D normal vibro-contact problem with friction. The dynamic road concept is introduced in order to characterize a particular stretch of road by total longitudinal, lateral, and normal forces and their geometric distributions in the contact patches. The off-road profiles are built by image sonification technique. The cross-sectional curves of off-roads before and after deformation, the contact between the tire and the road, the distribution of contact and friction forces in the contact domain, the natural frequencies and modes when the tire is in ground contact, are estimated. The approach is exercised on two particular problems and results compare favorably to existing analytical and numerical solutions. The feasibility of image sonification technique is useful to build a low-cost virtual reality environment with an increased degree of realism for driving simulators and higher user flexibility.
Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of functions. The sensor data is processed in a distributed fashion across the network, providing a large pool of resources in real time to meet stringent latency requirements.
Full Text Available Virtual reality (VR is one of the most challenging applications of computer graphics and is currently being applied in many fields. In neuroscience, VR can be used to create controlled Virtual Environments (VE where participants can perform experimental tasks. For example, VR can help neuroscientists to create virtual versions of classical neuroscience tasks, such as the Morris water maze, making it possible to use these tasks with human subjects (i.e., Astur et al., 1998. However, the relationship between VR and neuroscience is two-way. For neuroscientists, VR is more than just a tool: some aspects of subjects VR experience can be an object of study (Sanchez-Vives and Slater, 2005. VR researchers can investigate the processes that occur in the brain during navigation in VR environments and use the information to make their VR environments more compelling and effective. One of the concepts that they are studying is what has been called presence - an individuals subjective sensation of being in one place even if she is physically located somewhere else. In recent years, many studies of presence have applied brain imaging methods. Baumgartner et al. (2006 used EEG to analyze neural correlates of spatial presence in an arousing virtual environment with no interaction. In a subsequent study (Baumgartner et al., 2008, the same group used fMRI to monitor subjects brain activity. In recent works in our own group (Alcañiz et al., 2009; Rey et al, 2010, we have used Transcranial Doppler monitoring to analyze cognitive states related to presence during exposure to virtual environments providing different degrees of immersion and different options for navigation. The findings suggest that two-way cooperation between VR and neuroscience can make a significant contribution to research in coming years.

This paper presents the results of Phase II of the Ethnocultural Communities Facing AIDS Study, the sociocultural investigation of factors contributing to risk behaviour associated with HIV/AIDS in six ethnocultural communities in Canada in three urban sites. In Vancouver, the South Asian and Chinese communities were studied, the Horn of Africa and English-speaking Caribbean communities in Toronto and the Latin American and Arabic-speaking communities in Montreal. Results demonstrated that there are common elements across these ethnocultural communities that increase the risk for HIV transmission. HIV/AIDS awareness and prevention in ethnocultural communities must address sociocultural differences, particularly sex role differences between men and women in terms of power within relationships to negotiate for safer sexual practices.

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.

Contests of space and place in South African 'schoolscapes' are now not so much about 'race' as it is about nationalism and territoriality. While the politics of belonging unfolds and overtly manifests itself, a more covert, insidious and worrisome issue is that of the erosion of the social and cultural mores of Black immigrant students. Utilising social constructivism, case study approach and narrative inquiry, this study sets out to explore the socio-cultural experiences of Black female imm...

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

Results of Czech adult (older than 18 years) population testing are presented. Five somatic parameters were determined: body height (BH), body weight (BW), BMI (BMI), fat tissue percentage (%FAT), and waist hips rate (WHR), which were measured by machine Inbody 720, with some socio-cultural characteristics. Questionnaires were used to examine parameters of individual sport activity, life status, education level and magnitude of settlement. The presented results show negative trends. All obser...
Science education research predominantly shows that students improve their scientific understandings when they tinker (or pull apart) tools and simple household machines. In this study, the qualitative data collected took the form of online journal entries by final year, female, primary teacher trainees, who reflected upon their early childhood experiences of tinkering. Data analysis, from a socio-cultural perspective, shows that many of these fledgling teachers of technology face similar i...

The aim of this work was to elucidate the socio-cultural and economic value of a number of ecosystem services delivered by mountain agroecosystems (mostly grazing systems) in Euro-Mediterranean regions. We combined deliberative (focus groups) and survey-based stated-preference methods (choice modelling) to, first, identify the perceptions of farmers and other citizens on the most important ecosystem services and, second, to value these in economic terms according to the willingness to pay of ...

This paper discusses the sociocultural theory (SCT). In particular, three significant concepts of Vyogtskys 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 ...

Conversion to organic farming, along with driving forces and barriers, has been explored intensively during the past decade, while studies on localization and impacts of local socio-cultural processes on conversion to and diffusion of organic farming have been scarce. Concentrations of organic farms in Denmark differ according to county, and moreover there appeared to be large within-county variation in the density of organic farms. The present study explores the local aspects of conversion to o...

The high prevalence of antenatal common mental disorders in sub-Saharan Africa compared to high-income countries is poorly understood. This qualitative study explored the sociocultural context of antenatal mental distress in a rural Ethiopian community. Five focus group discussions and 25 in-depth interviews were conducted with purposively sampled community stakeholders. Inductive analysis was used to develop final themes. Worry about forthcoming delivery and fears for the womans survival we...
Dictation is considered as criteria for the skill of using the relationship between the sounds constituting the essence of the fundamental music education, and the symbols. Within the process of dictation, it is possible to understand how correctly the student comprehends the melody, harmony and rhythm- in other words, the basic elements of a music work. The aim of this study is to investigate the relationships between the dictation skills and socio-cultural variables. One of the factual ex...

The modern categorization also referred to as modern constitution has set Nature and Culture apart as two distinct ontological provinces, separating the pole of human beings and culture from the pole of non-humans and nature. Recent sociocultural anthropology and social studies of science have revisited the historical abyss between Nature and Culture and have shed light on the manifold conceptualizations of both terms across human cultures. For instance, non-Western indigenous relationships b...

Full Text Available El interés para realizar esta investigación sur- gió a partir de que Argentina recibe un número creciente de estudiantes de otros países latinoa- mericanos, atraídos por el idioma, el prestigio académico y las condiciones económicas. Como resultado del contacto intercultural, los estudian- tes atraviesan el proceso psicológico denominado aculturación, que implica cambios afectivos, comportamentales y cognitivos. En virtud de lo antedicho, este estudio se propuso identificar pre- dictores de adaptación sociocultural en función de variables sociodemográficas, culturales y psi- cológicas de estudiantes que decidieron realizar sus estudios universitarios en Argentina. Partici- paron 216 estudiantes migrantes que se encon- traban cursando diferentes carreras universita- rias, el 57% eran mujeres (n = 124 y el 43% varones (n = 92, con un promedio de edad de 24.18 años (DE = 4.55. El 86% (n = 186 había nacido en Latinoamérica. El restante 14% prove- nía de países de Europa y Asia. El tiempo pro- medio de residencia en Argentina era de 3.31 años. Se emplearon diferentes instrumentos dise- ñados ad hoc y/o adaptados para medir las varia- bles involucradas en el estudio. A partir de los re- sultados obtenidos, no se pudo corroborar la in- fluencia por parte de variables sociodemográficas (edad y tiempo de residencia. En cambio, entre las variables culturales se constató que percibir bajos niveles de discriminación y ansiedad in- tergrupal predice buenos niveles de adaptación sociocultural. En cuanto a las variables psicoló- gicas, se corroboró que el apoyo social y la sa- tisfacción percibida contribuyen a la adaptación sociocultural. En términos globales, las variables culturales y psicológicas predicen con mayor éxito la adaptación sociocultural en relación a las sociodemográficas.
Vygotskys sociocultural/cultural historical theory emphasised the notion of semiotic mediation or how thinking is transformed through signs (such as language) and cultural tools (such as drawings) from an intermental to an intramental plane. While the ideas of Vygotsky have become well-accepted within research in early childhood education in Australia, they are somewhat slower to be adopted within science education research. Yet they offer the potential for gaining new understandings of ho...

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 isol...

Abstract in english This article explains the developmental process and the level of efficiency first-graders from low sociocultural levels, who attend Mexican public schools, attain in their reading skills. An evaluation was made of 165 children during the 2004-2005 school year. Based on the results of the evaluation, [...] the children's silent and oral reading skills were described, in addition to their reading comprehension, at different times during their first year of formal schooling. The analysis used the variables of age at enrollment and the number of years of preschool attendance. The implications of the results are discussed and proposals are presented that may favor the development of literacy in children from low sociocultural levels, taking into consideration the ideas of educational psychology and research in the field.
Children learn their native language in a relatively rapid time and are able to communicate from very early using language. But is the acquisition of their native culture and native language dependent on each other (LeVine & Norman, 2001; Riesman, 1993)? The present study aims to investigate the extent to which parents provide their children with direct and indirect negative feedback while they are acquiring sociocultural aspects of their language. A group of parents (N=75) from three soc...

The use of patient centered care is promoted by Islam. Many of the countries with the highest percentage of diabetics are Muslim majority countries. The use of patient centered care in these areas is likely to reduce the burden of diabetes in these countries. However there are several challenges faced by the physicians working in these countries. Most of these challenges are sociocultural in origin and a thorough knowledge of the Islamic principles can help overcome these challenges.

Recent global reports indicate that women have made tremendous improvements in educational enrolment and labour participation but are woefully underrepresented in top leadership positions. Moreover, studies have shown that feminine leadership strategies are embraced but leadership is still perceived as a prerogative of men in many societies. This study therefore sought to explore the socio-cultural and organizational factors influencing the underrepresentation of women in educational leadersh...

Lettuce (Lactuca sativa L.) and its varieties are important vegetable crops worldwide. They are also well-known, rarely reported, causes of contact allergy. As lettuce allergens and extracts are not commercially available, the allergy may be underdiagnosed. The aims of this article are to present new data on lettuce contact allergy and review the literature. Lettuce is weakly allergenic, and occupational cases are mainly reported. Using aimed patch testing in Compositae-allergic patients, two re...
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...

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.
