    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.

    In our previous design of virtual Frisch-grid CdZnTe (CZT) detectors, the charge drift-lines can be terminated at the side surfaces before the carriers reach the collecting anode; this results in a loss of signal from the interacting events near the detector's edges. Here, we describe our new design for the anode contact that reduces these edge effects by focusing the electric field towards the detectors' central axes. Four detectors were fabricated with the new hybrid anode contact, and their performances were evaluated and compared to those from the previous design for our virtual Frisch-grid detectors. The results obtained for all four showed similar improvement: therefore, we illustrate them with the findings from one detector.

    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.

This situation highlights that the number of potential distance learners has been increasing in the Internet society. Besides, the terms and concepts of the Internet environments become to be spread out in this society like virtual reality. It is also possible to explain the characters of the Internet clearly via generating relatively new terms or concepts. “Virtual eye contact” concept is one of these. In this article, this concept is considered with a specific application of synchronous internet-based e-learning environments which is virtual classroom platform application. Explanation, technological infrastructure and benefits of this concept and training of the trainers to use this nonverbal communication type more powerfully are explained and discussed.

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

    Yin, Huabing; Zhou, Guangming

    2010-06-01

    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

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

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

    Lapeer, R J

    2005-01-01

    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

  16. Demonized Learners in Sociocultural Theory

    2016-06-01

    Full Text Available Within the frameworks of Sociocultural theory, particularly Vygotskian sociocultural theory and ZPD, Lave and Wenger’s CoP, and contemporary sociocultural theory, this paper seeks to examine the unfavourable scholarly portrayal of learners and their identities based on learners’ behaviours, attitudes, and beliefs about the social element of learning, particularly non-mainstream, non-normative behaviours. Such behaviours may be, to the learner, salient accompanying identity traits that were celebrated in one context but demonized in another. While learners have a degree of agency in subsequent critical, even hostile, settings, often this demonization leads to a degree of withdrawal, a retreat to grassroots rather than the mainstream, and a perpetration of accepted student norms. The deconstruction and critique of the ‘Good Language Learner’ gives insight into dominant discourses and metanarratives.  Further to this, we see implications of these academic discourses on practitioners, especially for Asian English language teachers, as well as recommendations.Keywords: Sociocultural theory, dominant, non-mainstream, Good Language Learner, metanarratives, social setting

    Analyses of the game Spore have centered on the important issues of accuracy of evolution content and engendering interest in science. This paper suggests that examination of the degree of scaffolding necessary to use the game in pedagogy is a missing part of the discussion, and then questions the longevity of the Spore discussion relative to the general dissatisfaction with the science presented in the game. The paper proposes that analysis of Spore and other technological tools in science education may be embedded in an historical moment which directs the discussion towards satisfying sociocultural and organizational needs and away from pedagogical ones.

  18. Sociocultural determinants of induced abortion

    International Nuclear Information System (INIS)

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

  19. Postural instability detection: aging and the complexity of spatial-temporal distributional patterns for virtually contacting the stability boundary in human stance.

    Directory of Open Access Journals (Sweden)

    Melissa C Kilby

    Full Text Available Falls among the older population can severely restrict their functional mobility and even cause death. Therefore, it is crucial to understand the mechanisms and conditions that cause falls, for which it is important to develop a predictive model of falls. One critical quantity for postural instability detection and prediction is the instantaneous stability of quiet upright stance based on motion data. However, well-established measures in the field of motor control that quantify overall postural stability using center-of-pressure (COP or center-of-mass (COM fluctuations are inadequate predictors of instantaneous stability. For this reason, 2D COP/COM virtual-time-to-contact (VTC is investigated to detect the postural stability deficits of healthy older people compared to young adults. VTC predicts the temporal safety margin to the functional stability boundary ( =  limits of the region of feasible COP or COM displacement and, therefore, provides an index of the risk of losing postural stability. The spatial directions with increased instability were also determined using quantities of VTC that have not previously been considered. Further, Lempel-Ziv-Complexity (LZC, a measure suitable for on-line monitoring of stability/instability, was applied to explore the temporal structure or complexity of VTC and the predictability of future postural instability based on previous behavior. These features were examined as a function of age, vision and different load weighting on the legs. The primary findings showed that for old adults the stability boundary was contracted and VTC reduced. Furthermore, the complexity decreased with aging and the direction with highest postural instability also changed in aging compared to the young adults. The findings reveal the sensitivity of the time dependent properties of 2D VTC to the detection of postural instability in aging, availability of visual information and postural stance and potential applicability as a

    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.

    Full Text Available Socio-cultural factors – 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 – 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 – Collectivism and Hierarchy – tends to reduce the international competitiveness; the other five affect it positively.

  1. Sociocultural perspective of substance use in India.

    Science.gov (United States)

    Sharma, H K

    1996-01-01

    The present communication focuses on a sociocultural perspective of substance use in a pluralistic and diverse culture. India has a history of use of plant products, viz., cannabis, opium, and home-brewed alcoholic beverages, within a defined sociocultural framework over five millennium. Cross sectional epidemiological studies in the field of substance use in different parts of India show that certain social groups are more "vulnerable" to substance use. Caste, religion, and local customs and traditions play a significant role in the choice of drugs, their consumption, and their control in rural/semiurban populations. The intercultural barriers are diminishing in urban populations, and even alien drugs like heroin have been introduced. The social and cultural implications of the traditional vis-a-vis the altering drug use scene are discussed at length. PMID:8908712

  4. A Sociocultural Approach to Recognition and Learning

    Directory of Open Access Journals (Sweden)

    Peter Musaeus

    2006-04-01

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

    Full Text Available In the article author analyze the socio-cultural phenomenon of education through the prism of its values and target components. Understanding of the role and place of education in society is not possible out of the human essence context. In living nature man appears as a phenomenon - this thesis is recognized the absolute majoriy of scientific and philosophical theories, concepts and doctrines, including non-humanistic oriented. It is known that man is a social being - society is environment for its full life. As Aristotle said, only the gods and the animals can live outside society. However, human nature does not imply a simple social existence in the form of an intensive exchange of information with similar entities and, based on this, building complex collective actions. The man has a mind that is capable of abstract thought, speech, language, complex psyche, important component of which is imagination. These features formed the basis of theoretical and methodological basis of the analysis of education as a phenomenon. The author indicated value and target measurement of socio-cultural phenomenon of education, which led to the conclusion about the need to rely on a properly organized philosophical and pedagogical knowledge, the importance of implementation in the educational process of program-target approach and the relevance of the audit of modern educational models for nonborrowed trainings, upbringing and socialization. doi: 10.17748/2075-9908-2016-8-2/1-124-126.

  16. Population change and socio-cultural values.

    Science.gov (United States)

    1982-06-01

    The developing countries of the world in general, and those of Asia and the Pacific in particular, recognize that unplanned population growth is a stumbling block to socioeconomic development. Discussion here focuses on population growth and social, economic, and institutional forces, which are referred to as sociocultural values. Generally, sociocultural values change sluggishly over time. The rate at which a country's sociocultural values change depends on several factors such as the stage of economic development and modernization and whether a country has an open or closed door policy. "The Value of Children Study: A Crossnational Study" by Fred Arnold et al. shows that there are positive and negative values attributed to children in the Asian countries. These are: positive general values--emotional benefits, economic benefits and security, self enrichment and development, identification with children, and family cohesiveness and continuity; negative general values--emotional costs, economic costs, restrictions on opportunity costs, physical demands, and family costs; large family values--sibling relationships, sex preferences, child survival; and small family values--maternal health and societal costs. Possibly the most formidable obstacle to the success of antinatalist population policies is that of religious values. It appears that the Muslim world is divided on the issue of fertility control. Conflicting views regarding fertility control is perhaps aggravated by the fact that there is no central international religious official hierarchy that issues out edicts. Despite the presence of a centralized religious hierarchy and a network of churches from the Vatican to the village levels among the Catholics, and a clearer elucidation of the Humanae Vitae, a liberal attitude to population regulation and family planning has emerged, largely because of the declining quality of life of the people resulting from unplanned births. Economic benefits of children include

  17. Learning as discourse change: A sociocultural mechanism

    Science.gov (United States)

    Wickman, Per-Olof; Östman, Leif

    2002-09-01

    This paper deals with a theoretical mechanism for learning and a methodological approach for analyzing meaning making in classroom talk and action. It examines the potential of the approach for illuminating learning on a discursive level, i.e., how discourses change and how individuals become participants of new practices. Our approach involves a high-resolution analysis of how meaningful relations are built in encounters between individuals and between individuals and the world. The approach is based mainly on the work of the later Wittgenstein, but also on pragmatism and sociocultural research. To demonstrate how our approach can be used, we analyze what university students learn during a practical on insects. We specifically demonstrate how the encounters with physical pinned insects contribute to the meaning students make and how these encounters interact with other experiences during laboratory work.

    2010-10-01

    Full Text Available Vygotsky‟s sociocultural theories have been widely referred to in the field of second language learning (SLL research (e.g. see Donato, 1994; Gutiérrez, 2003; Haas, 1996;Ohta, 2000; Swain, 2000; Warschauer & Kern, 2000. Adopting sociocultural theories offers researchers theoretical perspectives with which to examine language learning as a social practice, consider students as active participants in constructing learning processes, and investigate the interaction between different factors involved. To achieve this, this literature review aims to explore the central concepts of sociocultural theories and how such perspectives assist researchers in examining the interaction involved in the field of second language research.

However, we ourselves have remained behind the keyboard, with the screen of the monitor separating us from the world we are simulating. Recently, 3D on-line technology, developed first for games but now deployed in virtual worlds like Second Life, is beginning to make it possible for astrophysicists to enter their virtual labs themselves, in virtual form as avatars. This has several advantages, from new possibilities to explore the results of the simulations to a shared presence in a virtual lab with remote collaborators on different continents.

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

    2002-12-01

    OBJECTIVE: To discuss cognitive and sociocultural learning theory literature related to athletic training instructional and evaluation strategies while providing support for the application of these practices in the didactic and clinical components of athletic training education programs. DATA SOURCES: We searched Educational Resources Information Center (ERIC) and Education Abstracts from 1975-2001 using the key words social cognitive, sociocultural learning theory, constructivism, and athletic training education. Current literature in the fields of educational psychology and athletic training education provides the foundation for applying theory to practice with specific emphasis on the theoretic framework and application of sociocultural learning theory strategies in athletic training education. DATA SYNTHESIS: Athletic training educators must have a strong fundamental knowledge of learning theory and a commitment to incorporate theory into educational practice. We integrate literature from both fields to generate practical strategies for using sociocultural learning theory in athletic training education. CONCLUSIONS/RECOMMENDATIONS: Social cognitive and sociocultural learning theory advocates a constructive, self-regulated, and goal-oriented environment with the student at the center of the educational process. Although a shift exists in athletic training education toward more active instructional strategies with the implementation of competency-based education, many educational environments are still dominated by traditional didactic instructional methods promoting student passivity. As athletic training education programs strive to increase accountability, educators in the field must critically analyze teaching and evaluation methods and integrate new material to ensure that learning is maximized.

  9. Modelling the Sociocultural Contexts of Science Education: The Teachers' Perspective

    Science.gov (United States)

    Mansour, Nasser

    2013-02-01

    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.

    This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment. The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science. The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed.

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

    Full Text Available This article comes from a project sponsored by AECID of Educational Intervention on Social contexts and it approaches a specific dimension.As they contribute to solve several problems, sociocultural professionals claim for higher recognition. Given their superior studies they have been able to open a professional specific space. Their CV nowincludes aptitudes, abilities and skills toperform a job linked to several scenarios and contexts. The goals of this research are either to identify the key competences of the sociocultural animator that contribute towork efficiently andtodetect their educational needs.A multimethodological approach has been used. A survey was made to sociocultural animators allover Spain, with a reliability of 0,930 Cronbach’s alpha. Semi organized interviews were made to key informants. 376 surveys were received back. The SSP programwas used for statistical treatment for quantitative data, including variance and factorial analysis. Atlas-ti was used for qualitative data.In order toclassify theresults, competenceswere divided into three categories: methodological, planning and generic, confirming that the sociocultural workers have the monahigh degree.The factor analysis reflects that the three initially proposed working fields linked to professional performance became four with the empirical work.There is a good identification between the methodological and planning competences, while the generic is divided into: generic and transversal. A combination of them creates the professional profile, a compulsory reference source.

  3. Out of our minds: a review of sociocultural cognition theory

    Science.gov (United States)

    Tenenberg, Josh; Knobelsdorf, Maria

    2014-01-01

    Theories of mind are implicitly embedded in educational research. The predominant theory of mind during the latter half of the twentieth century has focused primarily on the individual mind in isolation, context-free problem-solving and mental representations and reasoning, what we refer to as cognitivism. Over the last two decades, CS Education researchers have begun to incorporate recent research that extends, elaborates and sometimes challenges cognitivism. These theories, which we refer to collectively as sociocultural cognition theory, view minds as cultural products, biologically evolved to be extended by tools, social interaction and embodied interaction in the world. Learning, under this perspective, is viewed as tool-mediated participation in the ongoing practices of cultural communities. In this paper, we pursue three goals. First, we provide a summary of the key principles in sociocultural cognition theory, placing this theory within a historical context with respect to the cognitive theories that it extends and challenges. Second, we integrate across different but related research efforts that all fall under the sociocultural cognition umbrella, using a uniform terminology for describing ideas represented within different discourse communities. And third, we reference a number of canonical sources in sociocultural cognition theory so as to serve as an index into this diverse literature for those wanting to explore further.

    2016-08-01

    In the United States, exposure to media violence is becoming an inescapable component of children's lives. With the rise in new technologies, such as tablets and new gaming platforms, children and adolescents increasingly are exposed to what is known as "virtual violence." This form of violence is not experienced physically; rather, it is experienced in realistic ways via new technology and ever more intense and realistic games. The American Academy of Pediatrics continues to be concerned about children's exposure to virtual violence and the effect it has on their overall health and well-being. This policy statement aims to summarize the current state of scientific knowledge regarding the effects of virtual violence on children's attitudes and behaviors and to make specific recommendations for pediatricians, parents, industry, and policy makers.

    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.

    2002-01-01

    The virtual articulator (VA) is intended for use as a tool for the analysis fo the complex static and dynamic occlusal relations. Its chief application is in individual diagnosis and the simulation of the mechanical articulator. As entry data, the VA requires digital, 3-dimensional representations of the jaws and patient-specific data on jaw movement. It then simulates jaw movement and provides a dynamic visualization of the occlusal contacts. If no patient-specific data are available, the modus operandi of the mechanical articulator can be simulated. Virtual reality (VR) techniques applied in computer-aided diagnosis are revolutionizing medical routine in many disciplines. Particularly in the field of dental engineering, VR combined with CAD/CAM technology has great potential in implant planning and design in terms of greater precision and shorter treatment duration. The geometry of teeth can be digitized, the implant models can be designed with specialized CAD systems, and the final implants can be manufactured with a CNC machine. In this context, the virtual articulator completes the digital manufacturing process.

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

    2016-01-01

    Mainland China has undergone profound changes dating back to the nineteenth century, including a contemporary period of rapid modernization that began in the 1980s. The result has been dramatic social, cultural, and economic shifts impacting the daily lives of Chinese people. In this paper, we explore the psychological implications of sociocultural transformation in China, emphasizing two central themes. First, rising individualism: findings from social and developmental psychology suggest that China's rapid development has been accompanied by ever-increasing adherence to individualistic values. Second, rising rates of depression: findings from psychiatric epidemiology point to increasing prevalence of depression over this same time period, particularly in rural settings. We argue that links between sociocultural and psychological shifts in China can be usefully studied through a cultural psychology lens, emphasizing the mutual constitution of culture, mind, and brain. In particular, we note that the link between social change, individualism, and rising mental illness deserves careful attention. Our review suggests that shifting values and socialization practices shape emotion norms of concealment and display, with implications for depressive symptom presentation. The challenge comes with interpretation. Increasing prevalence rates of depression may indeed be a general response to the rapidity of sociocultural change, or a specific consequence of rising individualism-but may also result from increasingly 'Western' patterns of symptom presentation, or improvements in diagnostic practice. We conclude by considering the challenges posed to standard universal models of psychological phenomena. PMID:27092093

  18. Study identifies socio-cultural factors affecting demographic behaviour.

    1994-01-01

    The United Nations Educational, Scientific, and Cultural Organization (UNESCO) is undertaking a project that will produce a state-of-the-art paper on sociocultural factors affecting demographic behavior. Particular emphasis will be placed on reproductive behavior in Africa, Asia, Latin America, and the Arab states region. The extent to which this information is incorporated in current population policies and programs will also be examined, and recommendations will be made. The factors to be studied include family and kinship structure; gender status and role; patterns of sexual relations and procreation in general and adolescent sexual behavior and fertility; religion, beliefs, customs, and traditions concerned with sexual relations and procreation; child rearing, socialization, and education; status and role of women; and sociocultural change, change agents, and influentials. The literature search will provide an inventory of methodologies. Guidelines on the use of the methodologies will be drafted for use by project personnel. These will later be tested in pilot studies in rural and urban communities in selected developing countries. The goal is to design programs that will accelerate contraceptive acceptance and sustain contraceptive practice by being sensitive to the sociocultural influences on the reproductive behavior of different subpopulations.

    2014-05-01

    Full Text Available Max Weber, one of the pioneers in bureaucratic organisational studies believes in the ultimate triumph of bureaucracy over the collegial culture of universities. This paper argues that rather than ultimate triumph of bureaucracy over the collegial culture of universities (Weber 1947, the interests of universities would be better served when the bureaucratic culture is designed to accommodate some core socio-cultural expectations of organizational members, without compromising productivity.  The research examined the implications of some selected sociocultural factors for bureaucratic practices in selected universities in Ghana through a mix method approach. The findings show that, the authority structures of the two universities typify the Weberian Ideal type bureaucracy with   hierarchical culture and standardized rules and procedures for carrying out every task. This notwithstanding, the societal culture was found to be influential in shaping the bureaucratic behaviour and conducts of organizations’ members. The paper aims at bringing to the fore the strength of the informal structures in reshaping bureaucratic culture and work behaviour, and the need to consider socio-cultural contexts in designing bureaucratic organizations.

    Weber, Gerhard W

    2015-02-01

    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

    Narat, Victor; Pennec, Flora; Simmen, Bruno; Ngawolo, Jean Christophe Bokika; Krief, Sabrina

    2015-10-01

    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

    Gender, age, and culturally specific beliefs are often considered relevant to observed variation in social interactions. At present, however, the scientific literature is mixed with respect to the significance of these factors in guiding moral judgments. In this study, we explore the role of each of these factors in moral judgment by presenting the results of a web-based study of Eastern (i.e., Russia) and Western (i.e., USA, UK, Canada) subjects, male and female, and young and old. Participants (n = 659) responded to hypothetical moral scenarios describing situations where sacrificing one life resulted in saving five others. Though men and women from both types of cultures judged (1) harms caused by action as less permissible than harms caused by omission, (2) means-based harms as less permissible than side-effects, and (3) harms caused by contact as less permissible than by non-contact, men in both cultures delivered more utilitarian judgments (save the five, sacrifice one) than women. Moreover, men from Western cultures were more utilitarian than Russian men, with no differences observed for women. In both cultures, older participants delivered less utilitarian judgments than younger participants. These results suggest that certain core principles may mediate moral judgments across different societies, implying some degree of universality, while also allowing a limited range of variation due to sociocultural factors.

    Background Ebola Virus Disease (EVD) is a condition with high fatality. Though the disease is deadly, taking precautions to reduce contact with infected people and their secretions can prevent cross- infection. In the 2014 EVD outbreak, socio-cultural factors were identified to be responsible for the spread of the disease in the three most affected countries in West Africa. In this light, we undertook this study to identify socio-cultural factors that may influence the prevention and containment of EVD in Ghana and ways to address such practices. Methods We conducted a descriptive qualitative study in five regions in Ghana. Twenty-five focus group discussions (5 in each region) with community members (4 in each region) and nurses (1 in each region) were conducted. In addition, forty (40) in-depth interviews were conducted with various stakeholders and opinion leaders; eight in each region. All interviews were recorded using a digital voice recorder and transcribed. With the aid of Nvivo 10 for windows, we analyzed the data using framework analysis. Results We found that socio-cultural practices, such as care of the body of dead and burial practices, widowhood rites and anointing children with water used to rinse the dead, were common. These practices require individuals coming into direct contact with either the dead or items used to take care of the dead. Social norms also require frequent handshakes in all social gatherings such as funeral, and religious congregations. We also found that self-medication (using herbs and orthodox medications) was a common practice. People use both biomedical and non-orthodox health outlets either simultaneously or in sequence in times of ill-health. Conclusion The study concludes that high risk socio-cultural practices were common among Ghanaians and generally perceived as indispensable. These high risk practices may hinder containment efforts in the event of an outbreak. Community leaders should be engaged in any social

  17. SYSTEMS AND SOCIOCULTURAL APPROACHES TO THE ORIGIN OF LANGUAGE

    Directory of Open Access Journals (Sweden)

    Sukhoverkhov A. V.

    2015-03-01

    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

    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.

    2014-04-01

    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.

    2016-07-01

    Angela Chapman and Allan Feldman (2016) conducted a study that aimed to exam how a group of diverse urban high school students were affected by the participation in a contextually based authentic science experience. The analysis of all data led the authors to conclude that the experience of authentic science positively influenced the science identity of students and promoted a shift in perceptions from stereotypical to more diverse views of scientists. For the purpose of this forum paper, we concentrated on the unexpected results of Hispanic students in the IAS instrument. In the authors' interpretation, Hispanic students were classified as non science identities because they do not feel recognized as a particular kind of student in that school, being possibly more marginalized than other students. We tried to expand the discussion bringing the contribution of a sociocultural approach of science construction and of science identity to enrich some of the issues involved. Our concise analysis does not allow conclusions about the Hispanic students' results, but we believe it helped to understand sociocultural problems involved in their science identity and to reveal the inequality in science production as one of these problems.

  8. Sociocultural competence-oriented curriculum for engineering education in Russia

    Directory of Open Access Journals (Sweden)

    Galanina Ekaterina

    2016-01-01

    Full Text Available Presently engineering education standards undergo vast changes due to the need in preparing “global” engineers. In the 21st century engineering education needs to adapt to the rapidly changing technical and sociocultural context. This need requires engineering education institutions to alter curricula on a regular basis. Universities tend to change curricula to meet the requirements of employers, industry and society because today engineers need to possess knowledge and practical skills not only in technical issues, but they also need to be competent in economics, ethics and social communication etc. Incorporating the competence and module-based approach along with accrediting engineering curricula also contribute to the transformation of higher engineering education in Russia. This matter is topical because today an engineer needs to acquire certain social and humanitarian qualities and skills specified by the requirements of Russian and international certification and accreditation organizations for engineering education. We suggest incorporating modules in humanities and social sciences into the structure of engineering curricula to make the process of forming sociocultural competence in Russian higher education institutions more efficient.

  9. Opposition to Women in Congregational Leadership: A Sociocultural Perspective

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Although many efforts have been made in time past in demonstrating that women are similar to men, there still appear to be a widespread persistent belief that women are indeed inferior to men even until today. What is even worrying is the theological backing that this sociocultural belief of society enjoys. One notices in the literature that God ordains, sanctions, and upholds the spiritual authority of women today as he did in time past as his official spokespersons and leaders of his people. However, the evidence and discussion presented in this paper demonstrate that problems with women being accepted as leaders by congregations, gender differences in pay and promotions, and the experiences and dissatisfaction of women clergy who feel constrained by these gender discrimination is widespread. The paper discusses this phenomenon and presents an often neglected perspective in the discourse – the sociocultural perspective. It interrogates the various stands on women and leadership in congregations. In doing this, the paper explores the position of women in the Old Testament through to the New Testament and the centuries following.

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

    Hut, P

    2006-01-01

    At the frontier of most areas in science, computer simulations play a central role. The traditional division of natural science into experimental and theoretical investigations is now completely outdated. Instead, theory, simulation, and experimentation form three equally essential aspects, each with its own unique flavor and challenges. Yet, education in computational science is still lagging far behind, and the number of text books in this area is minuscule compared to the many text books on theoretical and experimental science. As a result, many researchers still carry out simulations in a haphazard way, without properly setting up the computational equivalent of a well equipped laboratory. The art of creating such a virtual laboratory, while providing proper extensibility and documentation, is still in its infancy. A new approach is described here, Open Knowledge, as an extension of the notion of Open Source software. Besides open source code, manuals, and primers, an open knowledge project provides simul...

    Full Text Available In this paper, we present a virtual tactile model with the physically based skeleton to simulate force and deformation between a rigid tool and the soft organ. When the virtual trachea is handled, a skeleton model suitable for interactive environments is established, which consists of ligament layers, cartilage rings and muscular bars. In this skeleton, the contact force goes through the ligament layer, and produces the load effects of the joints , which are connecting the ligament layer and cartilage rings. Due to the nonlinear shape deformation inside the local neighbourhood of a contact region, the RBF method is applied to modify the result of linear global shape deformation by adding the nonlinear effect inside. Users are able to handle the virtual trachea, and the results from the examples with the mechanical properties of the human trachea are given to demonstrate the effectiveness of the approach.

  8. Creating opportunities to learn in mathematics education: a sociocultural perspective

    Science.gov (United States)

    Goos, Merrilyn

    2014-09-01

    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.

    2015-01-01

    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

  10. Exploring complex sociocultural situations through soft operational research

    Directory of Open Access Journals (Sweden)

    2010-08-01

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

  12. Socio-cultural effects on children's initiation of joint attention.

    2012-01-01

    Exchanging gazes with a social partner in response to an event in the environment is considered an effective means to direct attention, share affective experiences, and highlight a target in the environment. This behavior appears during infancy and plays an important role in children's learning and in shaping their socio-emotional development. It has been suggested that cultural values of the community affect socio-emotional development through attentional dynamics of social reference (Rogoff et al., 1993). Maturational processes of brain-circuits have been found to mediate socio-cultural learning and the behavioral manifestation of cultural norms starting at preschool age (Nelson and Guyer, 2011). The aim of the current study was to investigate the relations between cultural ecology levels and children's joint attention (JA). Initiation of JA bids was studied empirically as a function of the level of social load of the target toy (3 levels), the community level of adherence to traditional values (3 levels), parental education (2 levels), and gender. Sixty-two kindergarten aged children were enrolled in a structured toy-exploration task, during which they were presented with toys of various social loads, with social agents (i.e., mother and experimenter) present nearby, and non-social distracters presented intermittently. Measurements included the child's number of JA bids and the extent of positive affect. Analysis of variance indicated that the child's initiation of JA toward the social partner was affected by all levels of cultural ecology (i.e., toy's social load, adherence to tradition values, parental education, gender), thus supporting the study's hypotheses. The effects were such that overall, children, particularly girls' JA initiation was augmented in social toys and moderated by the socio-cultural variables. These results suggest that cultural ecology is related to children's JA, thereby scaffolding initiation of social sharing cues between children and

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.

  16. An Analysis on Vygotsky’s Sociocultural Theory in Communicative Language Teaching Mode

    Gao Qiong-fang

    2014-01-01

    Communicative Language Teaching (CLT) plays a vital role in foreign language teaching. Learners may improve their communicative language proficiency under CLT mode. Many researches on Vygotsky’s sociocultural theory show that learning as a social and cultural rather than individual phenomenon takes place through meaningful interaction with people, and thus the people in the environment are essential to the development of new knowledge. This paper mainly analyses Vygotsky’s sociocultural theory in CLT mode. The conclusions in this paper may help the readers gain an insight into the relations between the Vygotsky’s sociocultural theory and CLT as well as awaken the awareness of designing the activities for teaching.

  17. Virtual patients as activities: exploring the research implications of an activity theoretical stance.

    Science.gov (United States)

    Ellaway, Rachel H

    2014-09-01

    Virtual patients are computer-based simulators of patient encounters for the purposes of instruction, practice, and assessment. Although virtual patients have been around for some time they have yet to become part of mainstream medical education. A major reason for this would seem to be a lack of clarity as to what educational value virtual patients actually have. This paper argues that virtual patients should be seen as activities rather than artifacts and that activity theory can be used to generate different ways to frame scholarship in and around virtual patients. Drawing on the work of Leont'ev and Engeström this paper describes a range of perspectives based on the operations, actions, and objectives in and around virtual patients; the use of virtual patients to mediate activities; and the sociocultural context and the participants in virtual patient activities. This approach allows us to move beyond the 'does or does not work' discourse of much of the existing scholarship around virtual patients and, to an extent, around educational technologies as a whole. Activity perspectives, and activity theory in particular, offer new horizons for research and evaluation that address many of the limitations of intervention-based paradigms of inquiry.

    1992-01-01

    Eating disorders are a significant health problem for women today and therefore are a concern for the health professionals who work with women. The significance of this problem is addressed through epidemiological data from a Western cultural perspective. Many risk factors contribute to the development of these disorders. Broad categories including sociocultural, developmental, familial, and biological factors have been identified by clinicians and researchers. The sociocultural risk factors are the norms, standards, or values of a society. The sociocultural risk factors explored in this article are (a) the value of a thin physique, (b) the value of perfection, (c) the norm of dieting, (d) the influence of the media on these values, and (e) the choice of certain professions. The role of the health professional in prevention with respect to sociocultural factors is discussed. PMID:1478897

    Science.gov (United States)

    Baucal, Aleksandar; Zittoun, Tania

    2013-06-01

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

  7. Workplace learning in veterinary education: a sociocultural perspective.

    Science.gov (United States)

    Scholz, Emma; Trede, Franziska; Raidal, Sharanne L

    2013-01-01

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

    Science.gov (United States)

    Renzi, Ronald

    1996-01-01

    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.

    McCabe, Marita P; Ricciardelli, Lina A

    2003-02-01

    In 2 studies, the authors evaluated the role of parents, peers, and the media in body image and body-change strategies among adolescent boys and girls. The respondents for Study 1 (423 boys and 377 girls) completed the Body Image and Body Change Inventory (L. A. Ricciardelli & M. P. McCabe, 2002) and the Perceived Sociocultural Influences on Body Image and Body Change Questionnaire (M. P. McCabe & L. A. Ricciardelli, 2001b). Body mass index and age were also included in the analyses. Regression analyses demonstrated that sociocultural influences and feedback from the participant's best male friend were important predictors for all body-change strategies among boys. For girls, sociocultural influences and feedback from the participant's best female friend and mother were important predictors for body-change strategies. The most consistent predictor of weight loss, weight gain, and strategies to increase muscles was body-image importance. In Study 2, the authors examined the influence of the same sociocultural variables, as well as negative affect and puberty on body image and body-change strategies among a second group of 199 boys and 267 girls. The results demonstrated that a broad range of sociocultural influences predicted body-change strategies for boys and girls, with negative affect also having a unique influence for boys but not for girls. Puberty played a minor role, once other sociocultural variables were entered into the regression equation. The implications of these findings are discussed. PMID:12617344

    We investigate the hypothesis of a plurality of parallel and virtual worlds. It is assumed that sentient beings in each virtual world reach a stage of development that can create a virtual world to simulate the history of their own development. In this case, the virtual worlds are nested within each other, which put a severe restriction on the possible geometry of space-time. Discussed the draft geometry virtual worlds consistently displayed from one world to another. It is shown that in this...

  5. Experimental test of the theory of effect of natural strong narrowing of Mössbauer lines and a more general effect of collapse of the hyperfine structure because of fluctuations of the Fermi contact field. Role of virtual transitions in these effects

    To test the theory of the effect of natural strong narrowing (NSN) of Mössbauer lines on long-lived isomers and a more general effect of collapse of the hyperfine structure (CHFS) because of fluctuations of the Fermi contact field (S.V. Karyagin, JETP Lett. 98, 174 (2013)) with the use of the data obtained by the team led by Davydov (Yu.D. Bayukov et al., JETP Lett. 90, 499 (2009)), the yield of 88.034-keV gamma-ray photons from a silver plate with the 109 m Ag isomer has been analyzed in two variants: (i) the hyperfine structure is resolved and the yield depends on the angle ψ between the wave vector of the photon and the external field H ex, and (ii) the yield is independent of ψ because of CHFS. It has been shown that variant (ii) better reproduces the experimental data: experimental average count numbers at ψ = 0 and ˜π/2 differ from each other only in systematic error the same at 4.2 and 295 K and, moreover, the count numbers with the exclusion of resonance should be independent of ψ; this condition is strongly violated in variant (i) and is well satisfied in variant (ii). The threshold condition of the CHFS for the Fermi field has been obtained with allowance for virtual transitions. The collapse of the hyperfine structure is possible at any lifetimes of nuclear levels at any transitions not only in the gamma range but also in other radiation ranges. It results in the complete depolarization of nuclei and radiation. To estimate the Fermi field from experiments, the field | H ex| ˜ 104 G is necessary.

  6. Influence of Sociocultural Context on Language Learning in Foreign Countries

    Full Text Available Professional foreign language training is offered to cultivate the ability to master cross-cultural communication in the sphere of future professional activity. By means of intercultural competence of foreign language we are raising professional competence, too. In countries where English is the native language, it is taught to speakers of other languages as an additional language to enable them to participate in all spheres of life of that country. In many countries where it is an official language and language of instruction, as most communication outside school is in the local languages it is taught as language to learn other disciplines. These are two contrasting contexts for enhancing the English language skills. In both settings there are concerns about students’ difficulties in developing adequate English proficiency to successfully learn content through that language. This paper analyzes the influence of sociocultural factors on the students’ motivation to learn English in different countries, reveals main problems and difficulties in oral English teaching practice, illustrates the relationship between oral English teaching and cross-cultural communication competence. On the one hand, cross-cultural communication plays an essential role in oral English teaching; besides, oral English teaching promotes cross-cultural communication competence. On the other hand, in some countries English is not the prerequisite of future successful career. But anyway the author insists on consistency of English teaching concept with that of the world. Improving the students’ cross-cultural oral communication ability is impossible without laying equal stress on cross-cultural communication competence and oral English teaching.

    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.

  8. A monument to the player: preserving a landscape of socio-cultural capital in the transitional MMORPG

    `Adrir'Scott, Michael

    2012-12-01

    Massively multiplayer online role-playing games (MMORPGs) produce dynamic socio-ludic worlds that nurture both culture and gameplay to shape experiences. Despite the persistent nature of these games, however, the virtual spaces that anchor these worlds may not always be able to exist in perpetuity. Encouraging a community to migrate from one space to another is a challenge now facing some game developers. This paper examines the case of Guild Wars® and its "Hall of Monuments", a feature that bridges the accomplishments of players from the current game to the forthcoming sequel. Two factor analyses describe the perspectives of 105 and 187 self-selected participants. The results reveal four factors affecting attitudes towards the feature, but they do not strongly correlate with existing motivational frameworks, and significant differences were found between different cultures within the game. This informs a discussion about the implications and facilitation of such transitions, investigating themes of capital, value perception and assumptive worlds. It is concluded that the way subcultures produce meaning needs to be considered when attempting to preserve the socio-cultural landscape.

  10. Contact laser vaporization of the prostate for benign prostatic hypertrophy

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

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

    2012-12-01

    Full Text Available Family size in a particular society depends on marriage, family composition and adoption norms. It also depends upon modes of production, technological and socio-cultural forces. First purpose of this paper was to describe and compare family size (as a dependent variable and socio-cultural factor (as an independent variable between Muslim and Santal communities in rural Bangladesh. Second purpose of the paper was to examine how socio-cultural factors influence family size between the communities in rural Bangladesh. In so doing, 70 couples from Muslim and 30 couples from Santal communities from Kalna village, Tanore Upazila, Rajshahi, Bangladesh were randomly selected. Based on structural questionnaire method, including interview technique our descriptive findings, especially percentages suggested that family size, including usual family size, ideal family size, actual family size, expected family size, adoption practice was different between the two communities in the study area. In addition, results of regression analysis showed that socio-cultural factors, especially family, marriage, socio-economic status, and personal characteristics of the couples were affecting family size between the two communities in rural Bangladesh. The findings may be implied in social policy to change in family size in association with socio-cultural situations of the Muslim and Santal couples in rural Bangladesh.

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

    Energy Technology Data Exchange (ETDEWEB)

    Baldwin, T. E.; Poetsch, R.

    1977-08-01

    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.

  14. Realistic Haptic Rendering of Interacting Deformable Objects in Virtual Environments

    CERN Document Server

    Duriez, Christian; Kheddar, Abderrahmane; Andriot, Claude

    2008-01-01

    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...

    2012-06-01

    The pursuit of muscularity is an important body image concern among boys which has been described within sociocultural models of risk for eating disorders. This study explored a sociocultural model of disordered eating in which drive for thinness and pursuit of muscularity were both pathways to disordered eating among French adolescent boys. A sample of 146 adolescents completed a questionnaire assessing drive for thinness, drive for muscularity, media-ideal internalization, appearance comparison, and sociocultural pressure. The model was a good fit to the data and both drive for thinness and the pursuit of muscularity were related to disordered eating. Furthermore, internalization and appearance comparison mediated the relationships between pressure to increase muscle and both drive for muscularity and drive for thinness. Longitudinal research could help clarify the role of the pursuit of muscularity in the development of disordered eating and extreme body shape changing behaviors. PMID:22494958

    Evode Mukama

    2014-12-01

    Full Text Available This paper depicts a study carried out in Rwanda concerning university students who participated in a contest to produce short documentary films. The purpose of this research is to conceptualize these kinds of technology-based learning projects (TBLPs through a sociocultural perspective. The methodology included focus-group discussions and field notes to collect empirical data. The findings reveal that the more educational technologies capture objects of learning positioned in the students’ sociocultural proximity, the more focused the learners’ attention is on these objects. The study shows also that a change in learning projects may depend to a large extent on whether the technology relates to the students’ sociocultural proximity, that is, taking into consideration students’ physical, cultural, and contextual real world. The study recommends a community of learning/inquiry embedded in a collaborative, problem-solving dynamic involving cognitive support from peers, teachers, external specialists, and the wider community.

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

This paper compares the classroom experiences (CEs of two university students in their process of learning English as a foreign language (EFL. The CEs emerged from individual interviews, where classroom videos promoted reflection. The analysis revealed that cognitive, social and affective experiences directly influence the learning process and that those which refer to setting, learner’s personal background, beliefs and goal influence the learning process indirectly. The analysis also revealed the singularity of some of these CEs that led to their categorization as individual CEs (ICEs. When comparing the ICEs of the two participants, the importance of a sociocultural analysis of the classroom learning process becomes evident. We conclude with an analysis of the value of sociocultural theory in the study of classroom EFL learning and with the implications of this study for teachers and researchers.

    Because of the widespread repartition of allergens, allergic contact dermatitis is the most common inflammatory skin disease. It's the best model of dilated hypersensibility mediated by T lymphocytes cells. Atopic dermatitis and irritative dermatitis are to be distinguished to contact dermatitis. The aetiological diagnosis is the most important step of management of patients with that disease because it's the best way to avoid recurrences. The identification of cause is based on aetiological interrogatory and epicutaneous tests with 23 allergens completed with personnel products and specialised tests. Contact dermatitis can be classified according to results of aetiological management. In occupational contact dermatitis, contact dermatitis due to drugs, to metals, cosmetics, clothes and accessory and proteins. Management of patients with contact dermatitis is based on individual eviction, protection, cosmetovigilance, declaration of occupational dermatosis and allergovigilance. PMID:19102084

    This paper describes the Virtual Teacher that uses a set of rules to automatically adapt the way of teaching. These rules compose of two parts: conditions on various students' properties or learning situation; conclusions that specify different adaptation parameters. The rules can be used for general adaptation of each subject or they can be specific to some subject. The rule based system of Virtual Teacher is dedicated to be used in pedagogical experiments in adaptive e-learning and is therefore designed for users without education in computer science. The Virtual Teacher was used in dissertation theses of two students, who executed two pedagogical experiments. This paper also describes the phase of simulating and modeling of the theoretically prepared adaptive process in the modeling tool, which has all the required parameters and has been created especially for the occasion. The experiments are being conducted on groups of virtual students and by using a virtual study material.

It is assumed that sentient beings in each virtual world reach a stage of development that can create a virtual world to simulate the history of their own development. In this case, the virtual worlds are nested within each other, which put a severe restriction on the possible geometry of space-time. Discussed the draft geometry virtual worlds consistently displayed from one world to another. It is shown that in this case, the metric should be universal, depending only on the fundamental constants. There are examples of universal metrics obtained in Einstein's theory of gravitation and Yang-Mills theory

  5. Realization of Reconfigurable Virtual Environments for Virtual Testing

    Wen-Yan Wu; Zheng-Xu Zhao

    2005-01-01

    This paper presents the design and implementation of reconfigurable virtual environments (VEs) for virtual testing. It proposes a hybrid design approach that is derived from a so-called integration and composition of the reconfiguration strategy. The designing process has thus evolved from binding virtual objects using reconfiguration rules within the context of virtual testing scenarios. Therefore reconfigurable virtual environments are established with improved flexibility and scalability, tailored to a wide range of virtual testing applications. Those virtual environments integrate virtual testing scenarios, data acquisition, databases, rule mapping and application interfaces, which yield modular testing functions and an open-ended system architecture with a set of extensible interface tools to realize data exchange within reconfigurable VEs.This enables virtual testing scenarios to be reconfigured interactively based on real time data and communication between virtual environments and real environments. A virtual testing application has been implemented using reconfigurable VEs.

  6. Virtual Organizations: Beyond Network Organization

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

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

    Directory of Open Access Journals (Sweden)

    Victor A. Akujuru

    2014-07-01

    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.

  13. High availability using virtualization

    CERN Document Server

    Calzolari, Federico

    2009-01-01

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

  15. Contact materials for nanoelectronics

    KAUST Repository

    Alshareef, Husam N.

    2011-02-01

    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. © 2011 Materials Research Society.

  16. The virtual Haken conjecture

    CERN Document Server

    Agol, Ian; Manning, Jason

    2012-01-01

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

    2006-01-01

    Scientists and engineers are continually developing innovative methods to capitalize on recent developments in computational power. Virtual worlds and virtual exploration present a new toolset for project design, implementation, and resolution. Replication of the physical world in the virtual domain provides stimulating displays to augment current data analysis techniques and to encourage public participation. In addition, the virtual domain provides stakeholders with a low cost, low risk design and test environment. The following document defines a virtual world and virtual exploration, categorizes the chief motivations for virtual exploration, elaborates upon specific objectives, identifies roadblocks and enablers for realizing the benefits, and highlights the more immediate areas of implementation (i.e. the action items). While the document attempts a comprehensive evaluation of virtual worlds and virtual exploration, the innovative nature of the opportunities presented precludes completeness. The authors strongly encourage readers to derive additional means of utilizing the virtual exploration toolset.

    Maestre-Ferrín, Laura; Romero-Millán, Javier; Peñarrocha-Oltra, David; Peñarrocha-Diago, María

    2012-01-01

    The future of dental practice is closely linked to the utilization of computer-based technology, specifically virtual reality, which allows the dental surgeon to simulate true life situations in patients. The virtual articulator has been designed for the exhaustive analysis of static and dynamic occlusion, with the purpose of substituting mechanical articulators and avoiding their errors. These tools will help both odontologists and dental prosthetists to provide the best individualized treatment for each patient. The present review analyzes the studies published in the literature on the design, functioning and applications of virtual articulators. A Medline-PubMed search was made of dental journals, with the identification of 137 articles, of which 16 were finally selected. The virtual articulator can simulate the specific masticatory movement of the patient. During mandibular animation, the program calculates the sites where the opposing teeth come into contact. The studies made to assess the reliability of the virtual articulator show good correspondence in visualization of the number and position of the dynamic contacts. The virtual articulator is a precise tool for the full analysis of occlusion in a real patient.

    2009-10-01

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

    2015-03-01

    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.

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

    Full Text Available Resumen:Como la escuela en general, el ámbito de la educación superior también nos ofrece un escenario privilegiado para recabar evidencias del carácter sociocultural del pensamiento. Fundada en las exploraciones de Vigotzky y expandida por sus seguidores, la perspectiva sociocultural establece que nuestro pensamiento en general, y las funciones mentales superiores en particular, están por definición culturalmente mediados; y que no hay forma de no estar culturalmente situados cuando llevamos a cabo una acción, usualmente acorde con los patrones aceptados por el grupo social al que se pertenece (acción mediada. A partir de estas aseveraciones, este ensayo intenta justificar la importancia de un mayor conocimiento del contexto cultural que tiene lugar al interior de la educación superior, y una mejor comprensión de las implicaciones que las diferencias disciplinarias tienen en la enseñanza y el aprendizaje; dar cuenta de algunos hallazgos de incursiones de la investigación empírica a este respecto; y cerrar enmarcando los aportes concretos de este ejercicio dentro de una eminente preocupación por encontrar nuevas formas de articular la multiculturalidad; de integrar la diversidad que nos habita y nos estructura, y que forma parte de nuestras herencias y de nuestro presente cultural.Abstract:Just like school does in a general sense, higher education creates a privileged setting for collecting evidences of the sociocultural nature of thinking. Grounded in Vygotsky’s explorations and extended by his colleagues, the sociocultural perspective establishes that our thinking in a broad sense, and higher psychological functioning in particular, are by definition culturally mediated; and that there is no other way than to be culturally situated when taking action, usually following patterns accepted by the social group to which one belongs (mediated action.

    2006-01-01

    Through defining slide yield function and floating potential function of thermo-contact surface, the complementary equation of thermo-contact boundary has been reached, the fundamental equations to solve 3D thermo-contact coupled problem have been listed. On this foundation, the finite element equation and definite solution condition of contact heat transfer have been given out. Based on virtual work principle and contact element technology, the finite element equation of 3D elastic contact system has been deduced under the effect of thermal stress. The pseudo load brought by contact gap have been introduced into this equation in order to reflect the contact state change. During iteration, once contact rigidity matrix is formed, it won't change,which will make calculation reduce greatly.

  12. Lettuce contact allergy.

    Paulsen, Evy; Andersen, Klaus E

    2016-02-01

    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 recent Danish studies showed prevalence rates of positive lettuce reactions of 11% and 22%. The majority of cases are non-occupational, and may partly be caused by cross-reactivity. The sesquiterpene lactone mix seems to be a poor screening agent for lettuce contact allergy, as the prevalence of positive reactions is significantly higher in non-occupationally sensitized patients. Because of the easy degradability of lettuce allergens, it is recommended to patch test with freshly cut lettuce stem and supplement this with Compositae mix. As contact urticaria and protein contact dermatitis may present as dermatitis, it is important to perform prick-to-prick tests, and possibly scratch patch tests as well. Any person who is occupationally exposed to lettuce for longer periods, especially atopics, amateur gardeners, and persons keeping lettuce-eating pets, is potentially at risk of developing lettuce contact allergy.

  13. Current Trends in the Detection of Sociocultural Signatures: Data-Driven Models

    Energy Technology Data Exchange (ETDEWEB)

    Sanfilippo, Antonio P.; Bell, Eric B.; Corley, Courtney D.

    2014-09-15

    The harvesting of behavioral data and their analysis through evidence-based reasoning enable the detection of sociocultural signatures in their context to support situation awareness and decision making. Harvested data are used as training materials from which to infer computational models of sociocultural behaviors or calibrate parameters for such models. Harvested data also serve as evidence input that the models use to provide insights about observed and future behaviors for targets of interest. The harvested data is often the result of assembling diverse data types and aggregating them into a form suitable for analysis. Data need to be analyzed to bring out the categories of content that are relevant to the domain being addressed in order to train or run a model. If, for example, we are modeling the intent of a group to engage in violent behavior using messages that the group has broadcasted, then these messages need to be processed to extract and measure indicators of violent intent. The extracted indicators and the associated measurements (e.g. rates or counts of occurrence) can then be used to train/calibrate and run computational models that assess the propensity for violence expressed in the source message. Ubiquitous access to the Internet, mobile telephony and technologies such as digital photography and digital video have enabled social media application platforms such as Facebook, YouTube, and Twitter that are altering the nature of human social interaction. The fast increasing pace of online social interaction introduces new challenges and opportunities for gathering sociocultural data. Challenges include the development of harvesting and processing techniques tailored to new data environments and formats (e.g. Twitter, Facebook), the integration of social media content with traditional media content, and the protection of personal privacy. As these and other challenges are addressed, a new wealth of behavioral data and data analysis methods becomes

    2014-04-01

    Redirected walking algorithms imperceptibly rotate a virtual scene about users of immersive virtual environment systems in order to guide them away from tracking area boundaries. Ideally, these distortions permit users to explore large unbounded virtual worlds while walking naturally within a physically limited space. Many potential virtual worlds are composed of corridors, passageways, or aisles. Assuming users are not expected to walk through walls or other objects within the virtual world, these constrained worlds limit the directions of travel and as well as the number of opportunities to change direction. The resulting differences in user movement characteristics within the physical world have an impact on redirected walking algorithm performance. This work presents a comparison of generalized RDW algorithm performance within a constrained virtual world. In contrast to previous studies involving unconstrained virtual worlds, experimental results indicate that the steer-to-orbit keeps users in a smaller area than the steer-to-center algorithm. Moreover, in comparison to steer-to-center, steer-to-orbit is shown to reduce potential wall contacts by over 29%. PMID:24650985

    Jinbao Chen

    2014-01-01

    Full Text Available The grasping technology of the virtual-dexterous-robot (VDR hand plays a key role in the teleoperation of the space robot. For a grasp task in the virtual environment, the collision detection and virtual force calculation need to be implemented. Firstly, a tree-structure virtual scene including a VDR hand and a target object is built up with open inventor (OIV. Secondly, the collision manager provided by OIV is used for collision detection and the oriented bounding box (OBB is adopted to improve the real-time performance of collision detection. Thirdly, an algorithm is proposed for calculating the virtual force by using the contact deformation. And the contact deformation is calculated according to the transformation matrix between the coordinate systems of the two contact objects. Furthermore, the contact friction is also calculated by this matrix. Considering the virtual force, the modified stable grasping conditions are proposed which are suitable for the virtual grasping. Then a method is proposed for implementing the grasp or release operation by translating different nodes in the tree-structure scene, which can avoid destroying the tree structure. Finally, the viability and effectiveness of the proposed algorithms are proved by simulation experiments.

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

    Full Text Available Abstract Introduction: Library is one of the essential elements of universities which provide some important educational needs of students. Virtual education can not be exempted and virtual libraries are important support for virtual training programs. The purpose of this study is to evaluate the viewpoint of administrators and students in virtual education centers about the virtual library, its role and resources. Methods: This study was a descriptive survey. The research instrument was a researcher made questionnaire that its validity and reliability was confirmed. The study population consisted of 19 virtual training centers in Tehran city. Out of 19 centers, simple randomized sampling was done in five Centers. The sample size was 360 students. Data collection was conducted online and descriptive statistics using SPSS 18 and Excel software were used. Results: The results showed that viewpoints of administrators and students about the mission and services of virtual libraries in some cases were similar and in some cases were different. One of the administrators’ reasons for setting up a virtual learning system was lifelong learning, and lack of knowledge about virtual libraries was the reason for inadequate use of virtual libraries. The best format of virtual library from the administrators’ and students’ viewpoint, was portal document format (PDF. Conclusion: One of the most important function of a virtual library, is lifelong learning and empowering users to provide information and educational needs. The main reason for not setting up a virtual library is t lack of knowledge about it.

    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.

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.

    Foot dermatitis is a widespread condition, affecting men and women of all ages. Because of the location, this condition may present as a debilitating problem to those who have it. Allergic contact dermatitis involving the feet is frequently due to shoes or socks. The allergens that cause shoe dermatitis can be found in any constituent of footwear, including rubber, adhesives, leather, dyes, metals, and medicaments. The goal of treatment is to identify and minimize contact with the offending allergen(s). The lack of product information released from shoe manufacturers and the continually changing trends in footwear present a challenge in treating this condition. The aim of this study is to review the current literature on allergic contact shoe dermatitis; clinical presentation, allergens, patch testing, and management will be discussed. PubMed and MEDLINE databases were used for the search, with a focus on literature updates from the last 15 years. PMID:25000234

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE Allergic contact dermatitis is an immunologic reaction that tends to involve the surrounding skin and may even spread beyond affected sites. This skin disease is one of the more frequent, and costly dermatologic problems. Recent data from United Kingdom and United States suggest that the percentage of occupational contact dermatitis due to allergy may be much higher, thus raising the economic impact of occupational allergic contact dermatitis. There is not enough data about the epidemiology of allergic contact dermatitis in Indonesia, however based on research that include beautician in Denpasar, about 27,6 percent had side effect of cosmetics, which is 25,4 percent of it manifested as allergic contact dermatitis. Diagnosis of allergic contact dermatitis is based on anamnesis, physical examination, patch test, and this disease should be distinguished from other eczematous skin disease.

    Full Text Available Objective: The aim of this study was to investigate the frequency of contact sensitivity in patients with psoriasis, whether there was an association between clinical types and contact sensitivity, whether patch test is a factor that causes Koebner reaction and frequency of contact sensitivity against commonly used topical corticosteroids. Methods: Fifty patients with psoriasis and 50 healthy volunteers were included in this study and ‘European standard series' and test units of active ingredients of some corticosteroids were performed on their upper back. The patches were read on hours 24, 48 and on day 7 in order to detect delayed allergic reactions and also Koebner reaction. The results of both groups were compared by using chi-square test. Results: At the end of the patch test allergic reaction was observed in 7 of 50 (14% patients with psoriasis and 12 of 50 (24% healthy volunteers. There was no statistically significant difference between allergic reaction of study group and healthy volunteers. There was no statistically significant difference between the clinical types of psoriasis and allergic contact sensitivity. The frequency of reaction increased in individuals having a positive sensitivity history to any substance in both patient and control groups. Reaction to topical steroids was not seen in any patients. Koebner phenomenon due to patch test was also not seen in any patients. Conclusion: We did not show any association between psoriasis and contact sensitivity in this study. We believe that contact allergens should be determined by using patch test in psoriatic patients with a positive history to any substance.

The finding further revealed that six, out of seven of the independent variables in the study significantly contributed to maternal mortality in Edo South Senatorial District. The implications of these findings in maternal and child health care were highlighted. Conclusions:The study had shown that in addition to medical causes of maternal mortality, there are socio-cultural factors that contribute to women dying during pregnancy, labour and pueperium.

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

    Energy Technology Data Exchange (ETDEWEB)

    Kjerulf Petersen, L.; Holst Andersen, A.

    2009-02-15

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

    2016-02-01

    Full Text Available The following paper explores socio-cultural impacts of large-scale cruise liner tourism on the traditional bazaar (souq in the district of Mutrah. The souq is located opposite the port in the Omani capital Muscat. Large-scale cruise tourism in Muscat started only in 2004 and has increased in scale and numbers in the past years. 24 cruise vessels with around 7600 passengers arrived in Muscat in 2005. Seven years later 135 cruise liners carrying 257,000 tourists docked in Muscat. Due to this dramatic rise of international cruise ships, the socio-cultural impacts have increased for local residents, shop vendors/owners and tourists alike. To capture those socio-cultural impacts on Souq Mutrah, a survey of cruise tourists was conducted by a questionnaire. In addition, the researcher used participatory observation, counting, and in-depth interviews with different stakeholders of the local community and different types of tourists during the cruise seasons 2012/13 and 2013/14. Moreover, content analysis of statistics and local media publications were used. Results indicate that the souq has become “the core of a tourist bubble”, where crowding is a major problem and local residents avoid the place. The social carrying capacity of the souq has been reached. Omani vendors are leaving their businesses and renting their shops out to expatriates. Since contemporary cruise tourists are low spenders, expatriate shop sellers have become more aggressive.

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

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

    Purpose To identify perceptions of how sociocultural environment enabled and hindered physical activity (PA) participation. Design Community-based participatory research. Setting Two semirural and two urban communities located in Alberta, Canada. Participants Thirty-five people (74.3% females, 71.4% aged 25–64 years) across the four communities. Method PhotoVoice activities occurred over 3 months during the spring of 2009. Participants were asked to document perceived environmental attributes that might foster or inhibit PA in their community. Photographs and narratives were shared in one-on-one interviews. Line-by-line coding of the transcripts was independently conducted by two researchers using an inductive approach. Codes were arranged into themes and subthemes, which were then organized into the Analysis Grid for Environments Linked to Obesity (ANGELO) framework. Results Six main themes (accompanied by subthemes) emerged: sociocultural aesthetics, safety, social involvement, PA motivation, cultural ideas of recreation, and car culture. Representative quotes and photographs illustrate enablers and obstacles identified by participants. Conclusion This PhotoVoice study revealed how aspects of participants’ sociocultural environments shaped their decisions to be physically active. Providing more PA resources is only one step in the promotion of supportive environments. Strategies should also account for the beautification and maintenance of communities, increasing feelings of safety, enhancement of social support among community members, popularization of PA, and mitigating car culture, among others.

    2016-03-01

    Full Text Available In Costa Rica, many secondary students have serious difficulties to establish relationships between mathematics and real-life contexts. They question the utilitarian role of the school mathematics. This fact motivated the research object of this report which evidences the need to overcome methodologies unrelated to students’ reality, toward new didactical options that help students to value mathematics, reasoning and its  applications, connecting it with their socio-cultural context. The research used a case study as a qualitative methodology and the social constructivism as an educational paradigm in which the knowledge is built by the student; as a product of his social interactions. A collection of learning situations was designed, validated, and implemented. It allowed establishing relationships between mathematical concepts and the socio-cultural context of participants. It analyzed the impact of students’socio-cultural context in their mathematics learning of basic concepts of real variable functions, consistent with the Ministry of Education (MEP Official Program.  Among the results, it was found that using students’sociocultural context improved their motivational processes, mathematics sense making, and promoted cooperative social interactions. It was evidenced that contextualized learning situations favored concepts comprehension that allow students to see mathematics as a discipline closely related with their every-day life.

    The risk factors for compulsive exercise are unknown. This study aims to explore longitudinal sociocultural risk factors for compulsive exercise, using a 12-month prospective design. A sample of 332 male and female adolescents (aged 13-15 years at baseline) completed self-report measures of sociocultural risk factors and compulsive exercise at baseline and eating disorder psychopathology and compulsive exercise at 12-month follow-up assessment. Hierarchical regressions found that family and peer messages to become more muscular predicted compulsive exercise in boys, whereas feeling pressure from the media to be thin was a significant predictor of compulsive exercise in girls. These relationships remained significant when controlling for eating disorder psychopathology but became nonsignificant when initial levels of compulsive exercise were entered into the model. The findings suggest that sociocultural risk factors may contribute to the development of compulsive exercise but future research should utilise a younger sample and employ a longer follow-up period to identify true longitudinal effects.

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

  3. Differences in sociocultural environment perceptions associated with gender in science classrooms

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

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.

    Full Text Available The Arab minority in Israel is in the process of socio-cultural transformation, its force rising and splitting the society. Modernization, the Arab society undergoes, is influenced by the constant contacts with the Jew- ish nation representing in its majority the western culture, the other influenc- ing factors being technologies and mass media. Some changes affect the soci- ety in a positive way, whereas the global uncontrollable ones can bring about the system crisis and the full split of society. In order to retain the integrity it is necessary to control this process on the level of basic elements of cultural awareness by nurturing both cultural and moral values within the framework of educational system. One of the main functions of educational system is the man’s adapta- tion in society including its cultural aspect; and the upbringing process should be performed in the context of belonging to cultural and national val- ues. Well-balanced organic system of education combining cardinal, national and religious values can facilitate harmonious personal growth, and affect the society in a positive way. However, the Arab educational system in Israel faces some challenges in the course of implementing the value nurturing programs. They include the lack of political initiative and control over the educational system devel- opment performed by the Arabs; and the absence of the definite and steady value system that can be given to the growing generation by means of school education. To overcome the problem the author recommends developing and implementing a special training program focused on the value component de- velopment, as the students might have difficulty getting by in the real world without it.

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

    Science.gov (United States)

    Kyzer, Peggy Mckewen

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

    Many-body systems of strongly interacting Fermions are ubiquitous in nature, ranging from High-Tc superconductors and ultra-cold atomic gases to atomic nuclei and neutron stars. Theoretical predictions, recently verified by measurements on ultra-cold atomic gases, show that under certain conditions the universal behavior of systems composed of two kinds of fermions can be described using a single parameter, simply called the contact, which is a measure of the number of different-fermion pairs in close proximity. This paper discusses the relevance of the contact for very different systems: atomic nuclei, made of strongly-interacting neutrons and protons. Here we show that the high-momentum distributions of protons and neutrons in nuclei, dominated by correlated proton-neutron pairs mainly in a spin-triplet state, have the same momentum dependence as those of cold atoms, with a strength described by the contact. We use high-energy electron scattering data to extract a value for the nuclear contact consistent wi...

  3. [Contact allergies in musicians].

    Science.gov (United States)

    Gasenzer, E R; Neugebauer, E A M

    2012-12-01

    During the last years, the problem of allergic diseases has increased. Allergies are errant immune responses to a normally harmless substance. In musicians the allergic contact dermatitis to exotic woods is a special problem. Exotic rosewood contains new flavonoids, which trigger an allergic reaction after permanent contact with the instrument. High quality woodwind instruments such as baroque flute or clarinets are made in ebony or palisander because of its great sound. Today instruments for non-professional players are also made in these exotic materials and non-professionals may have the risk to develop contact dermatitis, too. Brass-player has the risk of an allergic reaction to the different metals contained in the metal sheets of modern flutes and brass instruments. Specially nickel and brass alloys are used to product flute tubes or brass instruments. Special problem arises in children: patients who are allergic to plants or foods have a high risk to develop contact dermatitis. Parents don't know the materials of low-priced instruments for beginners. Often unknown cheap woods from exotic areas are used. Low-priced brass instruments contain high amount of brass and other cheap metals. Physicians should advice musician-patients or parents about the risks of the different materials and look for the reason of eczema on mouth, face, or hands. PMID:23233303

  4. Contact: Releasing the news

    Science.gov (United States)

    Pinotti, Roberto

    The problem of mass behavior after man's future contacts with other intelligences in the universe is not only a challenge for social scientists and political leaders all over the world, but also a cultural time bomb as well. In fact, since the impact of CETI (Contact with Extraterrestrial Intelligence) on human civilization, with its different cultures, might cause a serious socio-anthropological shock, a common and predetermined worldwide strategy is necessary in releasing the news after the contact, in order to keep possible manifestations of fear, panic and hysteria under control. An analysis of past studies in this field and of parallel historical situations as analogs suggests a definite "authority crisis" in the public as a direct consequence of an unexpected release of the news, involving a devastating "chain reaction" process (from both the psychological and sociological viewpoints) of anomie and maybe the collapse of today's society. The only way to prevent all this is to prepare the world's public opinion concerning contact before releasing the news, and to develop a long-term strategy through the combined efforts of scientists, political leaders, intelligence agencies and the mass media, in order to create the cultural conditions in which a confrontation with ETI won't affect mankind in a traumatic way. Definite roles and tasks in this multi-level model are suggested.

    SMEs play an important role in manufacturing industry. But from time to time there is a shortage in resources to complete the particular order in time. Number of systems is introduced to produce digital information in order to support product and process development activities. Main problem is lack of opportunity for direct data transition within design system modules when needed temporary extension of design capacity (virtuality) or to implement integrated concurrent product development principles. The planning experience in the field is weakly used as well. The concept of virtual manufacturing is a supporting idea to solve this problem. At the same time a number of practical problems should be solved like information conformity, data transfer, unified technological concepts acceptation etc. In the present paper the proposed ways to solve the practical problems of virtual manufacturing are described. General objective is to introduce the knowledge-based CAPP system as missing module for Virtual Manufacturing in the selected product domain. Surface-centered planning concept based on STEP- based modeling principles, and knowledge-based process planning methodology will be used to gain the objectives. As a result the planning module supplied by design data with direct access, and supporting advising environment is expected. Mould producing SME would be as test basis.

    1996-06-01

    Virtual environments show great promise in the area of training. ALthough such synthetic environments project homeomorphic physical representations of real- world layouts, it is not known how individuals develop models to match such environments. To evaluate this process, the present experiment examined the accuracy of triadic representations of objects having learned them previously under different conditions. The layout consisted of four different colored spheres arranged on a flat plane. These objects could be viewed in either a free navigation virtual environment condition (NAV) or a single body position virtual environment condition. The first condition allowed active exploration of the environment while the latter condition allowed the participant only a passive opportunity to observe form a single viewpoint. These viewing conditions were a between-subject variable with ten participants randomly assigned to each condition. Performance was assessed by the response latency to judge the accuracy of a layout of three objects over different rotations. Results showed linear increases in response latency as the rotation angle increased from the initial perspective in SBP condition. The NAV condition did not show a similar effect of rotation angle. These results suggest that the spatial knowledge acquisition from virtual environments through navigation is similar to actual navigation.

  3. Virtual Reality in Psychology

    Directory of Open Access Journals (Sweden)

    2009-01-01

    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.

    Objective:To provide the virtual model of the temporal bone for improving 3-dimension (3D) visualization of the inner ear. Methods: Plastination technique was used to make equidistant serial thin sections 1.0 mm in thickness. On SGI workstation, a Contours+Marching Cubes algorithm was selected to reconstruct the temporal bone and intratemporal structures in 3D, then to view the middle ear, inner ear, and intratemporal structures which imitate the scenes observed by the traditional endoscopy. Results: The virtual model of the temporal bone was successfully constructed, with all reconstructed structures being represented individually or jointly and being rotated continuously in any plane. Virtual endoscopy improved 3D visualization of the middle ear, inner ear, and intratemporal structures. Conclusion: The reconstructed model can be used for the medical students to rehearse or review the surgeries on this part and for the surgeons to develop a new approach for operation. Virtual otoscopy stands as a promising new visualization technique for elucidating the structure and relation of the middle ear, inner ear, and intratemporal structures.

  17. Contact Graph Routing

    Science.gov (United States)

    Burleigh, Scott C.

    2011-01-01

    Contact Graph Routing (CGR) is a dynamic routing system that computes routes through a time-varying topology of scheduled communication contacts in a network based on the DTN (Delay-Tolerant Networking) architecture. It is designed to enable dynamic selection of data transmission routes in a space network based on DTN. This dynamic responsiveness in route computation should be significantly more effective and less expensive than static routing, increasing total data return while at the same time reducing mission operations cost and risk. The basic strategy of CGR is to take advantage of the fact that, since flight mission communication operations are planned in detail, the communication routes between any pair of bundle agents in a population of nodes that have all been informed of one another's plans can be inferred from those plans rather than discovered via dialogue (which is impractical over long one-way-light-time space links). Messages that convey this planning information are used to construct contact graphs (time-varying models of network connectivity) from which CGR automatically computes efficient routes for bundles. Automatic route selection increases the flexibility and resilience of the space network, simplifying cross-support and reducing mission management costs. Note that there are no routing tables in Contact Graph Routing. The best route for a bundle destined for a given node may routinely be different from the best route for a different bundle destined for the same node, depending on bundle priority, bundle expiration time, and changes in the current lengths of transmission queues for neighboring nodes; routes must be computed individually for each bundle, from the Bundle Protocol agent's current network connectivity model for the bundle s destination node (the contact graph). Clearly this places a premium on optimizing the implementation of the route computation algorithm. The scalability of CGR to very large networks remains a research topic

  19. Contact of surfaces and contact characteristics of offset surfaces

    Institute of Scientific and Technical Information of China (English)

    Lixin CAO; Hu GONG; Jian LIU

    2008-01-01

    Based on differential geometry, the contact problems of two surfaces are discussed in this paper. The relationship between the contact status of two sur-faces and that of offset surfaces are also analyzed. For a 5-axis NC machining, some research such as optimization of cutter location and calculation of the geometrical cusp height are important. The research results indicate that the relative normal curvature is an important geometrical invariant for describing the contact state of two surfaces. For point contact two surfaces, the calculation equation for the second order remained error is given. For line contact two surfaces, the condition of the second order line contact is that the principal directions and curvatures of the two surfaces are the same along the contact curve. If two surfaces keep the second order line contact, their two offset surfaces will also keep the second order line contact, and their third order remained errors are also uniform with that of the two offset surfaces.

    In contemporary urban societies multiple networks and systems interact, overlap, exist in parallel, converge, conflict etc. creating unforeseen complexity and less transparency. By exploring how layered networks of physical movement, service information, goods delivery, commercial communication etc....... are connected (and disconnected) we get a much better understanding of how to design and intervene regardless if we are thinking about public spaces in the city or new systems of service design. The many networks orchestrating and facilitating contemporary everyday life are dependent on the strategic sites...... where the networks meet and establish contact. Thus we argue for the usefulness of the notion of Critical Point of Contact (CPC) to deepen our understanding of the actual life within networks.

  2. Pediatric contact dermatitis

    Full Text Available Allergic contact dermatitis (ACD in children, until recently, was considered rare. ACD was considered as a disorder of the adult population and children were thought to be spared due to a lack of exposure to potential allergens and an immature immune system. Prevalence of ACD to even the most common allergens in children, like poison ivy and parthenium, is relatively rare as compared to adults. However, there is now growing evidence of contact sensitization of the pediatric population, and it begins right from early childhood, including 1-week-old neonates. Vaccinations, piercing, topical medicaments and cosmetics in younger patients are potential exposures for sensitization. Nickel is the most common sensitizer in almost all studies pertaining to pediatric contact dermatitis. Other common allergens reported are cobalt, fragrance mix, rubber, lanolin, thiomersol, neomycin, gold, mercapto mix, balsum of Peru and colophony. Different factors like age, sex, atopy, social and cultural practices, habit of parents and caregivers and geographic changes affect the patterns of ACD and their variable clinical presentation. Patch testing should be considered not only in children with lesions of a morphology suggestive of ACD, but in any child with dermatitis that is difficult to control.

    Tear fluid offers a potential route for non-invasive sensing of physiological parameters. Utilization of this potential depends on the ability to manufacture sensors that can be placed on the surface of the eye. A contact lens makes a natural platform for such sensors, but contact lens polymers present a challenge for sensor fabrication. This paper describes a microfabrication process for constructing sensors that can be integrated into the structure of a functional contact lens in the future. To demonstrate the capabilities of the process, an amperometric glucose sensor was fabricated on a polymer substrate. The sensor consists of platinum working and counter electrodes, as well as a region of indium-tin oxide (ITO) for glucose oxidase immobilization. An external silver-silver chloride electrode was used as the reference electrode during the characterization experiments. Sensor operation was validated by hydrogen peroxide measurements in the 10- 20 μM range and glucose measurements in the 0.125-20 mM range.

    Full Text Available Virtual Reality is a major asset and aspect of our future. It is the key to experiencing, feeling and touching the past, present and the future. It is the medium of creating our own world, our own customized reality. It could range from creating a video game to having a virtual stroll around the universe, from walking through our own dream house to experiencing a walk on an alien planet. With virtual reality, we can experience the most intimidating and gruelling situations by playing safe and with a learning perspective. In this review paper, we present our survey about virtual reality: the levels of virtual reality, the components used, the factors affecting the virtual environment, its origin, future and the challenges to overcome in order to obtain an impeccable virtual reality experience.

    2011-01-01

    Students in introductory physics courses struggle to understand virtual image formation by a plane mirror and the proper construction of ray diagrams. This difficulty, if not sufficiently addressed, results in further problems throughout the study of geometric optics. Specifically, students fail to apply proper graphical representation of light rays during investigations of the formation of real images by converging lenses and concave mirrors. We present a guided-inquiry activity based on the research-verified Physics by Inquiry text that incorporates a small and inexpensive billiards table, with billiard balls acting as "light". In this way, we approach the abstract concept of virtual images by relation to the concrete concept of physical reflection.

  9. Applied virtual reality

    International Nuclear Information System (INIS)

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

    2012-01-01

    Full Text Available Problem statement: The problem of moving from economic efficiency of the social one in the modern society is actualized. It is pointed out that the methodological basis for the solving questions of psychological education development are considered to be an anthropological psychology as a new scientific branch, which reflects the tendencies of development of psychology now a days. It is shown that there are various points of view on psychological education: self-organization as adaptation, self-organization as self-regulation and self-organization as self-determination. On the basis of these points of view psychology educational opportunities of a human being are considered as an individual life strategy aimed at success. Approach: The possibilities of different sociocultural environments and their contribution to psychological education of a person have been analyzed. The attention has been drawn to the fact, that sociocultural environment is the complex of social conditions of a person’s life, that allow to act in accordance with the structure and functions of the environment, choosing from the variety of possibilities those, which can be realized. The question of free choice of possible alternatives and creating of one’s own life story is discussed. Results: The motivation of achievement has qualitative differences depending on character of socio-cultural identity. If socio-cultural identity is positive, motivation of achieving the successes is a general life line. The revealed connection of components of positive functioning and showing the motivation of achievement has been considered in the context of our research as a full, subjective experience, which is of great importance for the person himself, as it is connected to basic human values and such everyday notions as happiness, happy life. When characterized the experience of psychological well-being by a person, it is necessary to mention that it supposes comparison of one

    Full Text Available Virtual tourism has been through at least three generations.The first is a special form of e-commerce, and no doubt it has much changed the way you plan your travel. Second generation of virtual tourism has exploited georeference: the user can know the services offered nearby and, with appropriate apps and augmented reality, receive information about places.An important contribution has been made in this field by social media (see Flickr, as well as Tripadvisor. The third generation of virtual tourism even replaces the travel experience: first proposing visits in virtual worlds, then in the real world. That allows tourism to social classes that are excluded.The goal is to send in the real place an "avatar", that can perform what tourist wants. Some experiments have been recently performed with robots, here a visit by drones is proposed. In particular, indoor visits are difficult because it is necessary to re-create a microgeodetic reference system in a closed and confined environment, to allow remote control and to ensure the protection of the cultural property. It has also to be considered the issue of the size of the drone, its autonomy and shooting video (which must be 360 degrees and high definition.The real experience is irreplaceable, but this form of tourism can find many interesting applications and strengthen real tourism.In conclusion, we believe that not only this performances are now within the reach of our technical capabilities, but  they also represent an effective response to certain social and cultural issues.

  2. Virtual nuclear weapons

    Energy Technology Data Exchange (ETDEWEB)

    Pilat, J.F.

    1997-08-01

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

    Zhai, Shumin; Milgram, Paul

    1992-03-01

    A project to develop a telerobotic `virtual control' capability, currently underway at the University of Toronto, is described. The project centers on a new mode of interactive telerobotic control based on the technology of combining computer generated stereographic images with remotely transmitted stereoscopic video images. A virtual measurement technique, in conjunction with a basic level of digital image processing, comprising zooming, parallax adjustment, edge enhancement, and edge detection has been developed to assist the human operator in visualization of the remote environment and in spatial reasoning. The aim is to maintain target recognition, tactical planning, and high-level control functions in the hands of the human operator with the computer performing low-level computation and control. Control commands initiated by the operator are implemented through manipulation of a virtual image of the robot system, merged with a live video image of the remote scene. This paper discusses the philosophy and objectives of the project, with emphasis on the underlying human factor considerations in the design, and reports the progress made to date in this effort.

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

    2005-02-01

    Ohmic contacts to semiconductor nanowires are essential components of many new nanoscale electronic devices. Equations for extracting specific contact resistance (or contact resistivity) from several different test structures have been developed by modeling the metal/semiconductor contact as a transmission line, leading to the development of equations analogous to those used for planar contacts. The advantages and disadvantages of various test structures are discussed. To fabricate test structures using a convenient four-point approach, silicon nanowires have been aligned using field-assisted assembly and contacts fabricated. Finally, specific contact resistances near 5 × 10 -4 Ω cm 2 have been measured for Ti/Au contacts to p-type Si nanowires with diameters of 78 and 104 nm.

    The incidence of breast cancer is on the rise in sub-Saharan Africa (SSA) and efforts at early diagnosis have not been very successful because the public has scant knowledge about the disease, a large percentage of breast cancer cases are diagnosed late and mainly rural SSA women's practice of breast self-examination is poor. In this paper, we argue that an examination of the social and cultural contexts of SSA that influence breast cancer diagnosis and management in the region is needed. We discuss the implications of sociocultural factors, such as gender roles and spirituality, on breast cancer diagnosis and management in SSA. PMID:26757491

The major objectives of this study were to explore, with a purposive sample, via seven focus groups, 40 African American college students, the following: How do (a) ethnic culture and (b) a "minoritized" status influence perceptions of sociocultural determinants in explaining increases in the incidence of suicide among African Americans? Thematic results of focus group discussions including the following: (a) racism, discrimination, and stereotyping; (b) U.S. individualism; (c) integration and cultural assimilation; and, (d) the prison industrial complex.
