Sample records for virtual sociocultural contact

  1. Transnational organizational considerations for sociocultural differences in ethics and virtual team functioning in laboratory animal science.

    Pritt, Stacy L; Mackta, Jayne

    2010-05-01

    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.

  2. Social Contact in Virtual Learning Environments

    Heilesen, Simon

    2013-01-01

    A common question is whether technology will replace social contact. In this article it is argued that it will not, provided that we learn to use the characteristics of new media constructively in designing for learning. The term “social”, in this context is taken to mean “purposeful communication......” and not “recreational socializing” (even if socializing may indeed facilitate learning)...

    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 Internet usage has been increasing among persons in the worldwide. 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.

  6. 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

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

    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

  8. Using visual cues of contact to improve interactive manipulation of virtual objects in industrial assembly/maintenance simulations.

    Sreng, Jean; Lécuyer, Anatole; Mégard, Christine; Andriot, Claude

    2006-01-01

    This paper describes a set of visual cues of contact designed to improve the interactive manipulation of virtual objects in industrial assembly/maintenance simulations. These visual cues display information of proximity, contact and effort between virtual objects when the user manipulates a part inside a digital mock-up. The set of visual cues encloses the apparition of glyphs (arrow, disk, or sphere) when the manipulated object is close or in contact with another part of the virtual environment. Light sources can also be added at the level of contact points. A filtering technique is proposed to decrease the number of glyphs displayed at the same time. Various effects--such as change in color, change in size, and deformation of shape- can be applied to the glyphs as a function of proximity with other objects or amplitude of the contact forces. A preliminary evaluation was conducted to gather the subjective preference of a group of participants during the simulation of an automotive assembly operation. The collected questionnaires showed that participants globally appreciated our visual cues of contact. The changes in color appeared to be preferred concerning the display of distances and proximity information. Size changes and deformation effects appeared to be preferred in terms of perception of contact forces between the parts. Last, light sources were selected to focus the attention of the user on the contact areas.

  10. Sociocultural approach to textbook

    Pešić Jelena M.

    2005-01-01

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

    , questioning and deferring contribute to the transformation and conventionalization of the material. These diverse sociocultural mediators are integrated into a partially coherent recollection by participants self-reflecting, or as Bartlett termed it, turning around upon their schemas. We demonstrate...... that this self-reflection is both a social and a psychological process, occurring because participants are responding to their own utterances in the same way that they respond to the utterances of other people. These empirical findings are used to make a case for using discursive data to look not only...

  12. Predictors of sociocultural adjustment among sojourning Malaysian students in Britain.

    Swami, Viren

    2009-08-01

    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.

  13. Sociocultural effects in neuropsychological assessment.

    Ostrosky-Solis, F; Canseco, E; Quintanar, L; Navarro, E; Meneses, S; Ardila, A

    1985-07-01

    The group selected for this evaluation consisted of 109 normal people with an average age of 25, coming from two different sociocultural levels (high and low) of Mexico City. All were completely evaluated by Luria's battery for neuropsychological assessment, adapted by Ardila, Ostrosky, and Canseco, 1981. This group of tests measures nine different areas: Motor Functions, Somatosensory Knowledge, Auditory Knowledge, Visuospatial Knowledge, Cognitive Processes, Language, Reading, Writing and Basic Calculations. For all of these, the higher performance standards were achieved by the subjects from the high sociocultural level. A significant interaction between sociocultural level and sex was observed. The differences between sexes appear only in subjects from the low sociocultural level. Factor analysis of the battery revealed that the most sensitive items to sociocultural level were those related on one hand, to the handling of complex structural and conceptual aspects of language and on the other hand, to the organization of motor sequences and in general motor programming. Research related to the differences found is reviewed and implications for clinical assessment are discussed.

  15. Demonized Learners in Sociocultural Theory

    Joanna Chen

    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

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

    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

  1. Virtual goods recommendations in virtual worlds.

    Chen, Kuan-Yu; Liao, Hsiu-Yu; Chen, Jyun-Hung; Liu, Duen-Ren

    2015-01-01

    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.

    2011-11-01

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

  5. Socio-Cultural Factors and International Competitiveness

    Madara Apsalone

    2015-12-01

    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.

  18. Sociocultural perspective of substance use in India.

    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.

  20. The role of cognitive apprenticeship in learning science in a virtual world

    Ramdass, Darshanand

    2012-12-01

    This article extends the discussion started by Margaret Beier, Leslie Miller, and Shu Wang's (2012) paper, Science games and the development of possible selves. In this paper, I suggest that a theoretical framework based on a sociocultural theory of learning is critical in learning in a virtual environment. I will discuss relevant research on the application of various components of the sociocultural perspective of learning in classroom environments and the potential for applying them in virtual worlds. I propose that research in science education should explore the processes underlying cognitive apprenticeship and determine how these processes can be used in virtual environments to help students learn science successfully.

    This article identifies six social-science research methodologies that will be useful for charting the sociocultural meaning of nanotechnology: web-based questionnaires, vignette experiments, analysis of web linkages, recommender systems, quantitative content analysis, and qualitative textual analysis. Data from a range of sources are used to illustrate how the methods can delineate the intellectual content and institutional structure of the emerging nanotechnology culture. Such methods will make it possible in future to test hypotheses such as that there are two competing definitions of nanotechnology - the technical-scientific and the science-fiction - that are influencing public perceptions by different routes and in different directions.

  2. EDUCATION AS A SOCIO-CULTURAL PHENOMENON

    Victor A. SHTURBA

    2016-01-01

    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.

  6. Population change and socio-cultural values.

    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

  8. Learning as discourse change: A sociocultural mechanism

    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.

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.

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

    Brunner, Nicolas; Popescu, Sandu; Skrzypczyk, Paul

    2011-01-01

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

    2007-01-01

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

  19. Virtual Labs and Virtual Worlds

    Boehler, Ted

    2006-12-01

    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

    This paper proposes the notion of activity-systems to denote a virtual frame of activity that requires mutually coordinated action. The underlying assumption is that such framings may support the informal learning and reflective practices of actors, and especially so, when they are provoking...... and challenging. It is suggested that the prevailing ‘traditions’ of collaborative learning and knowledge sharing need to be challenged and complemented, if we are to be able to support the variety and the diversity in the repertoires of virtual learning activities. In order to conceptualize such activity......-systems, the paper introduces the designing strategy referred to as virtual exploratories. Some of the advanced virtual worlds may inspire the design of such provoking and challenging virtual exploratories, and especially the Massively Multi-User Online Role-Playing Games (MMORPGS).

    Richards, Catherine; Korba, Larry W.; Shaw, Christopher D.; Green, Mark

    1994-04-01

    There are many ways to produce the sense of `presence' or telepresence in the user of virtual reality. For example attempting to increase the realism of the visual environment is a commonly accepted strategy. In contrast, this paper explores a way for the user to feel present in an unrealistic virtual body. It investigates an unusual approach, proprioceptive illusions. Proprioceptive or body illusions are used to generate and explore the experience of virtuality and presence outside of the normal body limits. These projects are realized in art installations.

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

    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.

  10. Virtual Specimens

    de Paor, D. G.

    2009-12-01

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

  13. A sociocultural perspective on mediated activity in third grade science

    Reveles, John M.; Kelly, Gregory J.; Durán, Richard P.

    2007-02-01

    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.

  14. Prevention of childhood obesity: sociocultural and familial factors.

    Bruss, Mozhdeh B; Morris, Joseph; Dannison, Linda

    2003-08-01

    This study examined sociocultural and familial factors related to the prevention of childhood obesity. Primary caregivers of 6- to 10-year-old children representing several ethnic populations in Saipan participated in 4 focus groups (N=32). Trained moderators used semi-structured interviews and qualitative methods were used in data analysis. A central theme with several related factors emerged. The theme was a conflict expressed by the primary caregiver between sociocultural values, family expectations, traditional dietary beliefs and attitudes, and knowledge about food and disease. These findings have important implications for designing culturally sensitive interventions for prevention of childhood obesity.

    Wayne, R.A. [Sandia National Labs., Albuquerque, NM (United States). Security Engineering Dept.

    1997-08-01

    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.

  17. Virtual Sustainability

    William Sims Bainbridge

    2010-09-01

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

  18. Virtual Violence.

    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 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.

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

    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.

  1. The virtual articulator.

    Bisler, A; Bockholt, U; Kordass, B; Suchan, M; Voss, G

    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.

  2. Virtual anthropology.

    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

    Galanina, E.; Dulzon, A.; Schwab, A.

    2015-10-01

    The aim of the present research is to discuss Tomsk Polytechnic University in respect of forming engineers’ sociocultural competence and teaching engineering ethics. Today international standards of training engineers cover efficient communication skills, ability to understand societal and environment context, professional and ethical responsibility. This article deals with the problem of contradiction between the need to form engineers’ sociocultural competence in Russian higher education institutions in order to meet the requirements of international accreditation organizations and the real capabilities of existing engineering curricula. We have described ethics teaching experience of TPU, studied the engineering master programs of TPU to see how the planned results are achieved. We have also given our recommendations to alter the structure of TPU educational curricula, which can also be applied in other higher education institutions.

  5. [Sexual development in the light of socio-cultural changes].

    Strauss, Bernhard

    2007-01-01

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

  6. Sociocultural contexts for the early development of semiotic production.

    Braswell, Gregory S

    2006-11-01

    Children constantly encounter signs during cultural practices, although many theories do not fully acknowledge sociocultural aspects of semiotic development. The author examines research on cultural practices and contexts in which children learn to produce signs involving representational drawing and pretend play. This work is contrasted with more individualistic views of semiotic development that fail to adequately address sociocultural aspects of semiotic functioning to varying degrees. The author also presents a theoretical model for understanding the structure of any sign system and for comparing semiotic systems, using examples from the drawing and pretense literatures. It is proposed that the sign-making practices in which children participate are shaped by a complex hierarchy of conventions.

  7. Strategy and methodology for the sociocultural reform of education

    Asmolov A.G.

    2013-01-01

    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.

    García, Rocío; Mircea, Teodor; Duque Sánchez, Elena

    2010-01-01

    The main premise of Vygotsky’s cultural-historical theory is that to promote learning, and thus development, educators must intervene in, and change, the students’ socio-cultural context. Vygotsky’s theory, however, has been misinterpreted and the opposite approach has been accepted: the teaching is adapted, according to the context. The result is widespread failure in schools. This article reclaims the true transformative meaning of Vygotskian theory and shows how successful schools in se...

  10. Involving Collaborative Interaction in EFL Classroom from Sociocultural Perspective

    李艺

    2016-01-01

    According to Vygotsky's theory of sociocultural theory (SCT), language use, classroom activity, and classroom structure are the primary means of mediation. In English as a Foreign Language (EFL) classroom, SCT provides a framework for teachers to involve collaborative interaction and constructive classroom approaches to support students ' development. By involving collaborative interaction, language teachers use it as a tool to reform the teaching mode, stimulating students ' potential ability, and assessing the improvement in students' learning experience.

  11. Regulation of positive and negative emotion: Effects of sociocultural context

    Sara A. Snyder

    2013-07-01

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

  12. 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.

  14. Passive Control Architecture for Virtual Humans

    Rennuit, Antoine; Merlhiot, Xavier; Andriot, Claude; Guillaume, François; Chevassus, Nicolas; Chablat, Damien; Chedmail, Patrick

    2007-01-01

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

  15. Sociocultural Influences on Moral Judgments: East–West, Male–Female, and Young–Old

    Arutyunova, Karina R.; Alexandrov, Yuri I.; Hauser, Marc D.

    2016-01-01

    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.

  16. Prioritized Contact Transport Stream

    Hunt, Walter Lee, Jr. (Inventor)

    2015-01-01

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

  18. Virtual World Astrosociology

    Bainbridge, William Sims

    2010-01-01

    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.

  19. Interpersonal Influence in Virtual Social Networks and Consumer Decisions

    Eduardo Botti Abbade

    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.

  20. Virtual screening of virtual libraries.

    Green, Darren V S

    2003-01-01

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

  5. Virtual Laboratories

    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...

  6. Preparing towards Preventing and Containing an Ebola Virus Disease Outbreak: What Socio-cultural Practices May Affect Containment Efforts in Ghana?

    Philip Baba Adongo

    2016-07-01

    Full Text Available 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.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.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.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 mobilization to modify these

  10. SYSTEMS AND SOCIOCULTURAL APPROACHES TO THE ORIGIN OF LANGUAGE

    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

  19. An Efficient Virtual Trachea Deformation Model

    Cui Tong

    2016-01-01

    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.

  20. Virtual Laboratories

    Hut, P.

    At the frontier of most areas in science, computer simulations playa 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 simulated dialogues between code developers, thus sharing not only the code, but also the motivations behind the code.

  1. HIGH SCHOOL TEACHER PROFESSIONAL CULTURE AS A SOCIOCULTURAL PHENOMENON

    2016-01-01

    Full Text Available In the article the questions of development of professional culture of teachers of high school in relation to social and cultural processes due to the expansion of ties between States, a deep understanding of the phenomenon of culture, the formation of a humanistic paradigm as the dominant socio-cultural process, intensification of integrative processes in science. University professors not only of professional actors responsible for the preparation of competent and marketable professionals, but also one of the most important socio-professional groups, active participants of the events in the country political, economic, sociocultural and scientific processes. The professional culture of a teacher is not created by itself. It manifests itself as the highest degree of professional competence development, complex system formation representing the totality of human values, professional values and personality traits, universal ways of cognition and technology teaching. In the modern sense of the professional culture of University teachers is one of socially significant indicators of literacy of a person, reflects the totality of its spiritual and material values, the degree of creative self-realization and actualization.

  2. Sociocultural factors contributing to teenage pregnancy in Zomba district, Malawi.

    Kaphagawani, Nanzen Caroline; Kalipeni, Ezekiel

    2016-09-30

    This study explores sociocultural and other risk factors associated with unplanned teenage pregnancy in Zomba district of Malawi. Data were obtained from 505 participants under the age of 20 years using a questionnaire administered through face-to-face interviews held at five antenatal clinics. The data were analysed using descriptive statistics, frequency tables and chi-square analysis which allowed comparative understanding of the sociocultural risk factors for planned and unplanned teenage pregnancy in Zomba district. The findings revealed that teenage pregnancy is a major health and social problem. Over 76% of the teenage respondents in the study had experienced unplanned pregnancy. Among the prominent factors that stood out in the analysis for this high rate of teenage pregnancy were early sex and marriage, low contraceptive use, low educational levels, low socio-economic status, lack of knowledge of reproductive and sexual health, gender inequity, and physical/sexual violence. The consequences on teenage mothers of unplanned pregnancy have been tragic and have compromised their physical, psychological and socioeconomic wellbeing, not just on them but also their families and society at large. The findings point to the need for a multi-sectoral approach to tackle the problem on teenage pregnancy in this district, and likely throughout Malawi.

  3. Sociocultural influences on science and on science identities

    Guerra, Andreia; Rezende, Flavia

    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.

  4. Socio-Cultural Impacts in the Formation of Urban Village

    Marpaung, B. O. Y.

    2017-03-01

    In Indonesia, a group of village people tends to move from one place to another and develops a living space to create a settlement. This research is conducted by taking an example of a particular ethnic group that leaves the forestry area to a new place in the city. After some time, this group of people creates a similar or adapted socio-cultural system adapted from their origin place. The purpose of this research is to examine the socio-cultural aspects that significantly influence the emergence of urban village. This influence is interpreted as social and cultural relations with the establishment of space and significance of urban village. By focusing on this issue, this research will trace the process of how a new and unplanned settlement could emerge. The process and elements are indispensable from social and cultural factors. Essentially, the shape of bulit space is a non-physical manifestation of local people, which is established from time to time. In this case, the research’s challenge lies on the circumstance in Indonesia where society and culture influence the emergence of urban village. Physical appearance can be identified as a tipology of settlement and morphology of urban village.

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

    Solomon Kofi Amoah

    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.

Las encargadas de preparar y servir los alimentos no siempre fueron las mujeres embarazadas; los alimentos percibidos peligrosos fueron consumidos y los benéficos presentaron consumo escaso. Resaltó la necesidad de capacitar a los profesionales de la salud para considerar al contexto sociocultural en la orientación alimentaria que proporcionen.

  7. EDITORIAL: Close contact Close contact

    Demming, Anna

    2010-07-01

    The development of scanning probe techniques, such as scanning tunnelling microscopy [1], has often been touted as the catalyst for the surge in activity and progress in nanoscale science and technology. Images of nanoscale structural detail have served as an invaluable investigative resource and continue to fascinate with the fantastical reality of an intricate nether world existing all around us, but hidden from view of the naked eye by a disparity in scale. As is so often the case, the invention of the scanning tunnelling microscope heralded far more than just a useful new apparatus, it demonstrated the scope for exploiting the subtleties of electronic contact. The shrinking of electronic devices has been a driving force for research into molecular electronics, in which an understanding of the nature of electronic contact at junctions is crucial. In response, the number of experimental techniques in molecular electronics has increased rapidly in recent years. Scanning tunnelling microscopes have been used to study electron transfer through molecular films on a conducting substrate, and the need to monitor the contact force of scanning tunnelling electrodes led to the use of atomic force microscopy probes coated in a conducting layer as studied by Cui and colleagues in Arizona [2]. In this issue a collaboration of researchers at Delft University and Leiden University in the Netherlands report a new device architecture for the independent mechanical and electrostatic tuning of nanoscale charge transport, which will enable thorough studies of molecular transport in the future [3]. Scanning probes can also be used to pattern surfaces, such as through spatially-localized Suzuki and Heck reactions in chemical scanning probe lithography. Mechanistic aspects of spatially confined Suzuki and Heck chemistry are also reported in this issue by researchers in Oxford [4]. All these developments in molecular electronics fabrication and characterization provide alternative

    2007-01-01

    A novel hybrid instrument of contact and non-contact measurement with large range is developed, and both measurement systems are based on a Linnik interference microscope and on white-light interference measuring techniques. The ambiguity presented in conventional monochromatic interferometers is not present in the contact and non-contact measurement, and they have a virtually unlimited unambiguous range. For the contact measurement, the vertical measuring range is ±5 mm with a resolution of 1 nm and the horizontal measuring range is ±25 mm in x-range and y-range with a resolution of 1.25 μm; for the non-contact measurement, the vertical measuring range is ±5 mm with a resolution of 1 nm and the horizontal resolution better than 0.5 μm.

    Rotation of three-dimensional objects by a two-dimensional mouse is a typical task in computer-aided design, operation simulations, and desktop virtual reality. The most commonly used rotation technique is a virtual trackball surrounding the object and operated by the mouse pointer. This article...... reviews and provides a mathematical foundation for virtual trackballs. The first, but still popular, virtual trackball was described by Chen et al. [CHECK END OF SENTENCE]. We show that the virtual trackball by Chen et al. does not rotate the object along the intended great circular arc on the virtual...... trackball and we give a correction. Another popular virtual trackball is Shoemake's quaternion implementation [CHECK END OF SENTENCE], which we show to be a special case of the virtual trackball by Chen et al..

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

    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.

    2007-12-01

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

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

    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.

    2006-01-01

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

  9. Virtual environment tactile system

    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.

  12. 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.

  13. Virtual World Security Inspection

    Nicholas Charles Patterson

    2012-06-01

    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.

  15. Sociocultural and Familial Influences on the Well-Being of Mexican Older Adults' Family Caregivers.

    Domínguez-Guedea, Miriam Teresa; Garcia, Abraham Ocejo

    2015-01-01

    The current study analyzed the influence of burden on the well-being of caregivers by exploring the mediating role of sociocultural and family factors. The study sample comprised 386 Mexican caregivers between ages 19 and 87 (mean age = 49.05; SD =12.41 years). The results from the current research showed that burden scores are negatively associated with well-being, sociocultural, and family scores. However, the effect of burden on subjective well-being is minimized by the mediation effect of sociocultural and family resources between burden and well-being. The complexities of sociocultural and family influences should be taken into account to change the prevailing individualistic approach within the current stress and family caregiver well-being paradigm.

  18. Contact Dermatitis in Pediatrics.

    Pelletier, Janice L; Perez, Caroline; Jacob, Sharon E

    2016-08-01

    Contact dermatitis is an umbrella term that describes the skin's reaction to contacted noxious or allergenic substances. The two main categories of contact dermatitis are irritant type and allergic type. This review discusses the signs, symptoms, causes, and complications of contact dermatitis. It addresses the testing, treatment, and prevention of contact dermatitis. Proper management of contact dermatitis includes avoidance measures for susceptible children. Implementation of a nickel directive (regulating the use of nickel in jewelry and other products that come into contact with the skin) could further reduce exposure to the most common allergens in the pediatric population.

  19. Religion as dialogical resource: a socio-cultural approach.

    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.

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

    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.

  1. [Main sociocultural aspects related to breast feeding in Malinalco, Mexico].

    Pérez-Gil Romo, S E; Rueda Arroniz, F; Ysunza Ogazón, A; Andrade Contreras, M D

    1991-06-01

    The present paper discusses data related to some sociocultural aspects on breast-feeding behavior among a group of women from a rural community in Mexico called Malinalco. A sample of 225 mothers with children aged less than 60 months, was selected. Several home visits were done in order to fill up a questionnaire, as well as to follow direct interviews according to some selected variables to the deepened, such as: schooling, occupation, place of children deliveries, breast-feeding behavior beliefs on breast-feeding abandonment, weaning practices, etc. The results showed that there is no relation between breast-feeding practices, income and school years; nevertheless, there is a certain tendency on early abandonment of breast-feeding in women with higher level of schooling. Some local beliefs about breast-milk production were detected, as well as some remedies to stimulate milk production and to cure certain breast-feeding problems. Data on weaning age and the commonest weaning food products are presented. The importance that cultural dimension has on breast-feeding studies is discussed, as well as the relevance of recognizing "the changes of concepts" within the process of cultural development itself, in order to understand them better and to propose solutions to the generated problems.

  3. Sociocultural Theory and its Role in the Development of Language Pedagogy

    Abdul Hameed Panhwar

    2016-12-01

    Full Text Available This paper reviews the literature on Vygotskian theory of Socio-cultural learning and constructivist approach to teaching and learning and attempts to relate the socio-cultural theory to constructivism. The purpose of the paper is to investigate the ways socio-cultural theory helps to develop language pedagogies. Critical analysis of the literature on the socio-cultural theory suggests that the theory has potential for forming new context-oriented language teaching-learning pedagogies which can help teachers in maximising the effectiveness of their teaching and their student’s learning. The review further suggests that the language pedagogies and activities developed from the sociocultural theory of Vygotsky may not only improve students’ language skills, but it also has potential to develop students’ cognition. Since theory promotes more and more communication of students with each other through scaffolding, that is, the Zone of Proximal development (ZPD in Vygotsky’s language. Thus, the theory directly points towards the promotion of student-centred learning by establishing learner autonomy. Keywords: socio-cultural theory, language, constructivism, pedagogies, students

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

    Gomella, Leonard G.; Lotfi, M. A.; Milam, Douglas F.; Albala, David; Reagan, Gary

    1994-05-01

    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.

  8. Virtual reality for engineering

    De Gennaro, Silvano; CERN. Geneva

    1996-01-01

    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.

  14. 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.

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

    Pazyura Natalia

    2016-06-01

    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.

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

    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...

  4. Exploration of Tactile Contact in a Haptic Display: Effects of Contact Velocity and Transient Vibrations.

    Gleeson, B T; Provancher, W R

    2011-01-01

    Experiments were conducted using a novel tactile contact rendering device to explore important factors of the tactile contact event. The effects of contact velocity and event-based transient vibrations were explored. Our research was motivated by a need to better understand the perception of the tactile contact event and to develop a means of rendering stiff surfaces with a nonspecialized haptic device. A passive tactile display, suitable for mounting on a Phantom robot, was developed and is capable of rendering the tactile sensation of contact on a fingertip over a range of velocities commonly experienced during everyday manipulation and tactile exploration. Experiments were conducted with this device to explore how tactile contact dynamics affect the perceived stiffness of a virtual surface. It was found that contact velocity does not have a significant effect on perceived stiffness. These results can be explained by prior research that defines perceived hardness (akin to stiffness) in terms of rate-hardness. However, in agreement with prior literature with stylus-based studies, the addition of transient vibrations to the contact event can, in some cases, increase the perceived stiffness.

    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.

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

    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.

  13. 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.

  14. Modeling Thermal Contact Resistance

    Kittel, Peter; Sperans, Joel (Technical Monitor)

    1994-01-01

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

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

    Uretsky, Elanah

    2008-11-01

    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.

  18. High availability using virtualization

    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...

  19. Impacts of geographical locations and sociocultural traits on the Vietnamese entrepreneurship.

    Vuong, Quan Hoang

    2016-01-01

    This paper presents new results obtained from investigating the data from a 2015 Vietnamese entrepreneurs' survey, containing 3071 observations. Evidence from the estimations using multinomial logits was found to support relationships between several sociocultural factors and entrepreneurship-related performance or traits. Specifically, those relationships include: (a) Active participation in entrepreneurs' social networks and reported value of creativity; (b) CSR-willingness and reported entrepreneurs' perseverance; (c) Transforming of sociocultural values and entrepreneurs' decisiveness; and, (d) Lessons learned from others' failures and perceived chance of success. Using geographical locations as the control variate, evaluations of the baseline-category logits models indicate their varying effects on the outcomes when combined with the sociocultural factors that are found to be statistically significant. Empirical probabilities that give further detail about behavioral patterns are provided; and toward the end, the paper offers some conclusions with some striking insights and useful explanations on the Vietnamese entrepreneurship processes.

However, a direct effect of cultural sensitivity and an indirect effect of intergroup anxiety on the levels of effectiveness perception were confirmed. This work contributes to previous studies on prejudice and leadership.

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

    Dawkins, K

    1996-01-01

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

    2013-01-01

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

    2017-01-01

    We study discrete-time quantum walks on Cayley graphs of non-Abelian groups, focusing on the easiest case of virtually Abelian groups. We present a technique to reduce the quantum walk to an equivalent one on an Abelian group with coin system having larger dimension. This method allows one to extend the notion of wave-vector to the virtually Abelian case and study analytically the walk dynamics. We apply the technique in the case of two quantum walks on virtually Abelian groups with planar Cayley graphs, finding the exact solution in terms of dispersion relation.

  9. The virtual Haken conjecture

    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".

  10. The sociocultural sustainability of livestock farming: an inquiry into social perceptions of dairy farming.

    Boogaard, B K; Oosting, S J; Bock, B B; Wiskerke, J S C

    2011-08-01

    Over the past 50 years, the scale and intensity of livestock farming have increased significantly. At the same time, Western societies have become more urbanised and fewer people have close relatives involved in farming. As a result, most citizens have little knowledge or direct experience of what farming entails. In addition, more people are expressing concerns over issues such as farm animal welfare. This has led to increasing public demand for more sustainable ways of livestock farming. To date, little research has been carried out on the social pillar of sustainable livestock farming. The aim of this study is to provide insights into the sociocultural sustainability of livestock farming systems. This study reviews the key findings of earlier published interdisciplinary research about the social perceptions of dairy farming in the Netherlands and Norway (Boogaard et al., 2006, 2008, 2010a and 2010b) and synthesises the implications for sociocultural sustainability of livestock farming. This study argues that the (sociocultural) sustainable development of livestock farming is not an objective concept, but that it is socially and culturally constructed by people in specific contexts. It explains the social pillar of the economics/ecological/social model sustainability in terms of the fields of tensions that exist between modernity, traditions and naturality - 'the MTN knot' - each of which has positive and negative faces. All three angles of vision can be seen in people's attitudes to dairy farming, but the weight given to each differs between individuals and cultures. Hence, sociocultural sustainability is context dependent and needs to be evaluated according to its local meaning. Moreover, sociocultural sustainability is about people's perceptions of livestock farming. Lay people might perceive livestock farming differently and ascribe different meanings to it than experts do, but their 'reality' is just as real. Finally, this study calls for an ongoing

  11. Critical Socio-Cultural Elements of the Intercultural Endeavour of English Teaching in Colombian Rural Areas

  15. Contact angle hysteresis explained.

    Gao, Lichao; McCarthy, Thomas J

    2006-07-04

    A view of contact angle hysteresis from the perspectives of the three-phase contact line and of the kinetics of contact line motion is given. Arguments are made that advancing and receding are discrete events that have different activation energies. That hysteresis can be quantified as an activation energy by the changes in interfacial area is argued. That this is an appropriate way of viewing hysteresis is demonstrated with examples.

  16. Virtual articulator for the analysis of dental occlusion: an update.

    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.

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

    Bonamonte, Domenico; Foti, Caterina; Romita, Paolo; Vestita, Michelangelo; Angelini, Gianni

    2014-01-01

    The diagnosis of skin diseases relies on several clinical signs, among which color is of paramount importance. In this review, we consider certain clinical presentations of both eczematous and noneczematous contact dermatitis in which color plays a peculiar role orientating toward the right diagnosis. The conditions that will be discussed include specific clinical-morphologic subtypes of eczematous contact dermatitis, primary melanocytic, and nonmelanocytic contact hyperchromia, black dermographism, contact chemical leukoderma, and others. Based on the physical, chemical, and biologic factors underlying a healthy skin color, the various skin shades drawing a disease picture are thoroughly debated, stressing their etiopathogenic origins and histopathologic aspects.

    We investigate the concept of participation from the perspective of quality of the contact in the communicative interactions between participants. We argue for the need for an academic-personal competence that qualifies the human contact central in all Participatory Design (PD) activities as a way...... to contribute to “an era of participation.” We describe a contact perspective in PD developed through a collaboration with body-oriented psychotherapeutic research that have specialized experiences in investigating open-minded contact and authentic meetings as body-related experiences....

  1. Allergic Contact Dermatitis

    Meltem Önder

    2009-03-01

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

  5. Virtual neutron scattering experiments

    Overgaard, Julie Hougaard; Bruun, Jesper; May, Michael

    2017-01-01

    We describe how virtual experiments can be utilized in a learning design that prepares students for hands-on experiments at large-scale facilities. We illustrate the design by showing how virtual experiments are used at the Niels Bohr Institute in a master level course on neutron scattering....... In the last week of the course, students travel to a large-scale neutron scattering facility to perform real neutron scattering experiments. Through student interviews and survey answers, we argue, that the virtual training prepares the students to engage more fruitfully with experiments by letting them focus...... on physics and data rather than the overwhelming instrumentation. We argue that this is because they can transfer their virtual experimental experience to the real-life situation. However, we also find that learning is still situated in the sense that only knowledge of particular experiments is transferred...

  9. Development of Networked Virtual Experiment System Based on Virtual Campus

    Tian-tai Guo

    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.

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

    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.

  4. Performance of redirected walking algorithms in a constrained virtual world.

    Hodgson, Eric; Bachmann, Eric; Thrash, Tyler

    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%.

  5. Active Grasping Control of Virtual-Dexterous-Robot Hand with Open Inventor

    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.

    Shi Yu; Xiao Yougang; Chen Guoxin

    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.

  7. The Problems of Socio-Cultural Community in Patani and Penang: A Comparative Study

    2016-01-01

    Full Text Available There are different socio-cultural in a society. Socio-cultural is a lifestyle and civilization for some society, born from the grip and tendency of community member in various fields of life, to give satisfaction and stimulate the development of community life. Diversity of perception and socio-cultural is one of the stem that led to the conflict. This is one convention that is already known to the public equally there is a conflict with humans or nature. Everything is becoming common place of human life. But what is true in a society has received attention by the authors in exposing matters of human problems or crisis faced by the community. In this paper we will discuss the problem of socio-cultural force in Patani and Penang society in Montri Sriyong’s novel and Azmi Iskandar Merican’s novel. To discuss this problem, two novels from Thailand and Malaysia was chosen as the corpus of analysis, namely Rusni (2012 and Aci Patmabi (2012 by Azmi Iskandar Merican. Montri Sriyong is the winner of SEA WRITE AWARD in 2007 and Azmi Iskandar Merican is a new comer writer who has colored the world of creative writing in Malaysia. Both novels express Malay socio- cultural community. Various problems and chaos that has prevailed in the society so as to bring the various conflicts faced by people who are forced together in Patani and Penang. Scope of this paper will examine whether the causes that give rise to stem the outbreak of Malay socio-cultural communities in Patani and Penang. Cultural studies theory used as a platform to study these novels. The theory of cultural studies that serve as the foundation lead to cultural element in the form of literary works, as there are cultural objects, ways of life and beliefs. Acquired discussion will serve as a reference to show the reality of life truth Patani and Penang society as proposed by both the author.

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

    Thompson, V L Sanders; Harris, J; Clark, E M; Purnell, J; Deshpande, A D

    2015-01-01

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

  9. Wait-time, classroom discourse, and the influence of sociocultural factors in science teaching

    Jegede, Olugbemiro J.; Olajide, Janet O.

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

  10. Allergic contact dermatitis.

    Becker, Detlef

    2013-07-01

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

    2015-06-01

    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.

    Keith, M; Lyne, A; Brooke, J

    2007-01-01

    The Pulsar Virtual Observatory will provide a means for scientists in all fields to access and analyze the large data sets stored in pulsar surveys without specific knowledge about the data or the processing mechanisms. This is achieved by moving the data and processing tools to a grid resource where the details of the processing are seen by the users as abstract tasks. By developing intelligent scheduling middle-ware the issues of interconnecting tasks and allocating resources are removed from the user domain. This opens up large sets of radio time-series data to a wider audience, enabling greater cross field astronomy, in line with the virtual observatory concept. Implementation of the Pulsar Virtual Observatory is underway, utilising the UK National Grid Service as the principal grid resource.

    1999-05-01

    The advantages of contact air abrasion techniques are readily apparent. The first, of course, is the greatly increased ease of use. Working with contact also tends to speed the learning curve by giving the process a more natural dental feel. In addition, as one becomes familiar with working with a dust stream, the potential for misdirecting the air flow is decreased. The future use of air abrasion for deep decay removal will make this the treatment of choice for the next millennium.

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

    Hall, Dennis E.; Scherrer, Deborah K.; Sventek, Joseph S.

    1980-05-01

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

  15. Double pendulum contact problem

    Špička J.

    2014-06-01

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

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

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

    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

    2002-01-01

    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.

    2000-10-01

    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.

  13. Virtual Reality in Psychology

    Nigel Foreman

    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.

  18. Virtual Sensor Test Instrumentation

    Wang, Roy

    2011-01-01

    Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of

  19. Acculturation Attitudes and Sociocultural Adaptation of Chinese Mainland Sojourners in Hong Kong

    Yuanyi Ma

    2015-12-01

    Full Text Available Within these years, there has been a significant increase in the number of Chinese Mainland sojourners studying in Hong Kong. Due to the huge differences in various aspects like language, culture, cultural value, it would be considerably difficult for the Chinese Mainland students to adapt to the Hong Kong environment. This article investigates the ways for a group of doctoral students from Chinese Mainland to acculturate in Hong Kong. With the help of questionnaires, the difficulties that the sojourners have encountered in social situations are measured. It is found out that age and gender may have influenced the participants’ acculturation strategies, and interpersonal relationship is that which the subjects have the most difficulties with, while academic domain is the area with the least difficulties. Meanwhile, the results have shown that competence of local language is not a determinant factor of the sociocultural adaptation, and female subjects seem to adapt better than male subjects.

    Silvania Sousa do Nascimento

    2008-12-01

    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.

    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...

  7. Acrylate Systemic Contact Dermatitis.

    Sauder, Maxwell B; Pratt, Melanie D

    2015-01-01

    Acrylates, the 2012 American Contact Dermatitis Society allergen of the year, are found in a range of products including the absorbent materials within feminine hygiene pads. When fully polymerized, acrylates are nonimmunogenic; however, if not completely cured, the monomers can be potent allergens.A 28-year-old woman is presented, who had her teeth varnished with Isodan (Septodont, Saint-Maur-des-Fossés, France) containing HEMA (2-hydroxyethyl methacrylate) with no initial reaction. Approximately 1 month later, the patient developed a genital dermatitis secondary to her feminine hygiene pads. The initial reaction resolved, but 5 months later, the patient developed a systemic contact dermatitis after receiving a second varnishing.The patient was dramatically patch test positive to many acrylates. This case demonstrates a reaction to likely unpolymerized acrylates within a feminine hygiene pad, as well as broad cross-reactivity or cosensitivity to acrylates, and possibly a systemic contact dermatitis with systemic re-exposure to unpolymerized acrylates.

    Matthys, Erin; Zahir, Amir; Ehrlich, Alison

    2014-01-01

    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.

    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. The management is prevention of allergen exposure, symptomatic treatment, and physicochemical barrier /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  2. Allergic contact dermatitis.

    Gober, Michael D; Gaspari, Anthony A

    2008-01-01

    Allergic contact dermatitis is a classic example of a cell mediated hypersensitivity reaction in the skin. This occurs as a result of xenobiotic chemicals penetrating into the skin, chemically reacting with self proteins, eventually resulting in a hapten-specific immune response. It is precisely because of this localized immune response that allergic signs and symptoms occur (redness, edema, warmth and pruritus). It has been known for years that conventional T-cells (CD4+ or CD8+ T-cells that express a T-cell receptor alpha/Beta) are critical effectors for this reaction. There is emerging evidence that innate immune lymphocytes such as invariant Natural killer T-cells and even Natural killer cells may play important role. Other T-cell types such as Tregulatory cells and the IL-10 secreting Tregulatory cells type I are likely to be important in the control (resolution) of allergic contact dermatitis. Other cell types that may contribute include B-cells and hapten-specific IgM. Additionally, epidermal Langerhans cells have been ascribed an indispensable role as an antigen presenting cell to educate T-cells of the skin immune system. Studies of mice that lack this cell type suggest that Langerhans cells may be dispensible, and may even play a regulatory role in allergic contact dermatitis. The identity of the antigen presenting cells that complement Langerhans cells has yet to be identified. Lastly, Keratinocytes play a role in all phases of allergic contact dermatitis, from the early initiation phase with the elaboration of inflammatory cytokines, that plays a role in Langerhans cell migration, and T-cell trafficking, through the height of the inflammatory phase with direct interactions with epidermotrophic T-cells, through the resolution phase of allergic contact dermatitis with the production of anti-inflammatory cytokines and tolerogenic antigen presentation to effector T-cells. As the understanding of allergic contact dermatitis continues to improve, this will

    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.

  5. Nurturing the Growing Generation’s Values in the Process of Socio-Cultural Transformation of Society

    2012-01-01

    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. 

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

    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.

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

    Ghafar Samar, Reza

    2013-01-01

    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.

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

    Sonderegger, Andreas; Sauer, Juergen

    2013-05-01

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

  9. Sociocultural context as a facilitator of student learning of function concepts in mathematics

    Evangelina Díaz Obando

    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.

    Objective:To investigate the socio-cultural factors that contribute to Maternal Mortality in Edo South Senatorial District. Methods:The population of the study was made up of 2 157 females of reproductive age and multi-stage random sampling technique was used. The instrument for data collection was a self developed structured and validated questionnaire with a reliability of 0.82. Focus group discussion (FGD) and in-depth interview guide were employed to complement the instrument. Inferential statistics of multiple regressions were also employed to test the hypotheses at 0.05 level of significance. Results:The results showed that the socio-cultural variables when taken together contributed positively to maternal mortality [R2=0.32;CV=16.5;df=7). 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.

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

    Jegede, Olugbemiro J.; Akinsola Okebukola, Peter

    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.

    2014-05-01

    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.

  18. Thermal Contact Conductance

    Salerno, Louis J.; Kittel, Peter

    1997-01-01

    The performance of cryogenic instruments is often a function of their operating temperature. Thus, designers of cryogenic instruments often are required to predict the operating temperature of each instrument they design. This requires accurate thermal models of cryogenic components which include the properties of the materials and assembly techniques used. When components are bolted or otherwise pressed together, a knowledge of the thermal performance of such joints are also needed. In some cases, the temperature drop across these joints represents a significant fraction of the total temperature difference between the instrument and its cooler. While extensive databases exist on the thermal properties of bulk materials, similar databases for pressed contacts do not. This has often lead to instrument designs that avoid pressed contacts or to the over-design of such joints at unnecessary expense. Although many people have made measurements of contact conductances at cryogenic temperatures, this data is often very narrow in scope and even more often it has not been published in an easily retrievable fashion, if published at all. This paper presents a summary of the limited pressed contact data available in the literature.

  19. The Nuclear Contact Exists

    Hen, O; Piasetzky, E; Miller, G A; Sargsian, M M

    2014-01-01

    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...

  20. Irritant contact dermatitis.

    Ale, Iris S; Maibach, Howard I

    2014-01-01

    Irritant contact dermatitis (ICD) is the most common form of contact dermatitis. It represents the cutaneous response to the toxic/physical effects of a wide variety of environmental agents. Nowadays, it is recognized that irritancy does not represent a single monomorphous entity but rather a complex biologic syndrome with diverse pathophysiology and clinical manifestations. The clinical presentation is highly variable depending on several factors, including properties and strength of the irritant, dose, duration and frequency of exposure, environmental factors, and skin susceptibility. The pathophysiological mechanism depends on activation of the innate immune system and involves skin barrier disruption, cellular changes, and release of proinflammatory mediators that directly recruit and activate T lymphocytes. The diagnosis of irritant contact dermatitis is often clinical, and involves a comprehensive history and examination, as well as the exclusion of allergic contact dermatitis with patch testing. Recent advances in understanding the pathogenesis as well as better awareness of the clinical significance of ICD will lead to a improved care for our patients.

  2. [Contact allergies in musicians].

    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.

  3. Contact: Releasing the news

    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.

  5. Curating Virtual Data Collections

    Lynnes, Chris; Leon, Amanda; Ramapriyan, Hampapuram; Tsontos, Vardis; Shie, Chung-Lin; Liu, Zhong

    2015-01-01

    NASAs Earth Observing System Data and Information System (EOSDIS) contains a rich set of datasets and related services throughout its many elements. As a result, locating all the EOSDIS data and related resources relevant to particular science theme can be daunting. This is largely because EOSDIS data's organizing principle is affected more by the way they are produced than around the expected end use. Virtual collections oriented around science themes can overcome this by presenting collections of data and related resources that are organized around the user's interest, not around the way the data were produced. Virtual collections consist of annotated web addresses (URLs) that point to data and related resource addresses, thus avoiding the need to copy all of the relevant data to a single place. These URL addresses can be consumed by a variety of clients, ranging from basic URL downloaders (wget, curl) and web browsers to sophisticated data analysis programs such as the Integrated Data Viewer.

    Brooks, Frederick P., Jr.

    1991-01-01

    The utility of virtual reality computer graphics in telepresence applications is not hard to grasp and promises to be great. When the virtual world is entirely synthetic, as opposed to real but remote, the utility is harder to establish. Vehicle simulators for aircraft, vessels, and motor vehicles are proving their worth every day. Entertainment applications such as Disney World's StarTours are technologically elegant, good fun, and economically viable. Nevertheless, some of us have no real desire to spend our lifework serving the entertainment craze of our sick culture; we want to see this exciting technology put to work in medicine and science. The topics covered include the following: testing a force display for scientific visualization -- molecular docking; and testing a head-mounted display for scientific and medical visualization.

    The Virtual Solar Observatory (VSO) concept contains software tools for searching, manipulating, and analyzing data from archives of solar data at many different observatories around the world (Hill 2000). The VSO not only provides fast and reliable access to the existing solar data, but also represents a powerful and unique machinery to perform numerical simulations for the evolution of a variety of different phenomena associated with solar activity. Two Mexican Universities, Universidad Nacional Autónoma de México and the Universidad de Sonora, are working together to create the Mexican Virtual Solar Observatory (MVSO) that will be part of a wider National effort. In this work we present a general description of the MVSO project, as well as the advances obtained in the development of Graphical User Interfaces (GUI) to Remotely Perform Numerical Simulation of the Evolution of Coronal Mass Ejection in the Interplanetary Medium.

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

    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

    2015-08-01

    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. 

  15. Virtual Quantum Subsystems

    Zanardi, Paolo

    2001-01-01

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

  17. Virtual nuclear weapons

    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.

  20. Virtual blood bank.

    Wong, Kit Fai

    2011-01-24

    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.

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

  3. Online information Impact in the virtual destination image formation

    2014-05-01

    Full Text Available The influence of the destination image in the decision process and choice of destination by tourists is transverse to its intangible nature. Recent studies expand and modify the conventional image constructs specifying information sources transmitted through the internet. The scenario resulting from the literature review allows us to understand the importance of experience for touristic activity and theoretical proposition of virtual tourism as "virtual tourist experience", its determinants and its implications for the overall image destination formation. This study presents a literature review base to the empiric research proposal whose general objective comprises the analysis of the influence of factors, such as interactivity, in online communication and contact with virtual tourism experiences online in image destination formation and image destination.

  5. Allergic contact dermatitis in children.

    Fontana, E; Belloni Fortina, A

    2014-12-01

    Allergic contact dermatitis is an inflammatory skin disease (delayed type hypersensitivity reaction) that accounts for up to 20% of all childhood dermatitis. Allergic contact dermatitis represents a clinical manifestation of contact sensitization and usually occurs at skin sites that have come into contact with the allergen. The clinical features of allergic contact dermatitis are itchy eczematous lesions. Prevalence of contact sensitization varies between 27% and 96% of children with suspected contact dermatitis. The relationship between contact sensitization and atopic dermatitis has been widely discussed but only conflicting data have been reported. Epicutaneous patch testing is the gold standard for the diagnosis of allergic contact dermatitis. The most common allergens detected in children are: metals, topical medicaments, fragrances, and preservatives. The first line management of allergic contact dermatitis in children is to avoid the offending allergens identified with the patch test and a topical corticosteroid therapy.

    Numerous plant species and their derivatives can cause skin reactions through a variety of mechanisms: irritative contact dermatitis, allergic contact dermatitis, contact urticaria and photodermatitis. We present a case of irritative contact dermatitis after exposure to the sap of Agave americana. The skin symptoms in this case have only been described on rare occasions; although this condition usually presents with a papulovesicular rash, in this patient it appeared as purpuric lesions in the contact area.

  7. Contact of surfaces and contact characteristics of offset surfaces

    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.

  9. Contact Graph Routing

    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

  12. A NEW STATIC MECHANICS MODEL TO SOLVE CONTACT PROBLEMS IN MECHANICAL SYSTEMS

    陆志华; 叶庆泰

    2004-01-01

    The coupling of the local contact problems between the components and the deformation of the components in the mechanical system were discovered. A series of coordinate systems have been founded to describe the mechanical system with the contact problems. The method of isolating the boundary of contact body from others has been used to describe the constraint between the contacting points. A more generalized static mechanics model of the mechanical system with the contact problems has been founded through the principle of virtual work. As an application, the model was used to study the multi-teeth engagement problems in the inner meshed planet gear systems. The stress distribution of contact gears was got. A test has verified that the static contact model and the computational method are right.

  13. /Au Back Contacts

    Paudel, Naba R.; Compaan, Alvin D.; Yan, Yanfa

    2014-08-01

    We report on the fabrication and characterization of CdTe thin-film solar cells with Cu-free MoO3- x /Au back contacts. CdTe solar cells with sputtered CdTe absorbers of thicknesses from 0.5 to 1.75 μm were fabricated on Pilkington SnO2:F/SnO2-coated soda-lime glasses coated with a 60- to 80-nm sputtered CdS layer. The MoO3- x /Au back contact layers were deposited by thermal evaporation. The incorporation of MoO3- x layer was found to improve the open circuit voltage ( V OC) but reduce the fill factor of the ultrathin CdTe cells. The V OC was found to increase as the CdTe thickness increased.

  15. Occupational protein contact dermatitis.

    Barbaud, Annick; Poreaux, Claire; Penven, Emmanuelle; Waton, Julie

    2015-01-01

    Occupational contact dermatitis is generally caused by haptens but can also be induced by proteins causing mainly immunological contact urticaria (ICU); chronic hand eczema in the context of protein contact dermatitis (PCD). In a monocentric retrospective study, from our database, only 31 (0.41%) of patients with contact dermatitis had positive skin tests with proteins: 22 had occupational PCD, 3 had non-occupational PCD, 5 occupational ICU and 1 cook had a neutrophilic fixed food eruption (NFFE) due to fish. From these results and analysis of literature, the characteristics of PCD can be summarized as follows. It is a chronic eczematous dermatitis, possibly exacerbated by work, suggestive if associated with inflammatory perionyxix and immediate erythema with pruritis, to be investigated when the patient resumes work after a period of interruption. Prick tests with the suspected protein-containing material are essential, as patch tests have negative results. In case of multisensitisation revealed by prick tests, it is advisable to analyse IgE against recombinant allergens. A history of atopy, found in 56 to 68% of the patients, has to be checked for. Most of the cases are observed among food-handlers but PCD can also be due to non-edible plants, latex, hydrolysed proteins or animal proteins. Occupational exposure to proteins can thus lead to the development of ICU. Reflecting hypersensitivity to very low concentrations of allergens, investigating ICU therefore requires caution and prick tests should be performed with a diluted form of the causative protein-containing product. Causes are food, especially fruit peel, non-edible plants, cosmetic products, latex, animals.

  19. The ethnography of virtual reality

    Gavrilović Ljiljana 1

    2004-01-01

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

  1. Pediatric contact dermatitis

    Sharma Vinod

    2010-01-01

    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.

Implementations range from hydrology and environmental sciences to solid earth sciences. Among the goals of VOs are to provide search/ query, access and use of distributed, heterogeneous data resources. With many of these goals being met and usage increasing, new demands and requirements are arising. In particular there are two of immediate and pressing interest. The first is use of VOs by non-specialists, especially for information products that go beyond the usual data, or data products that are sought for scientific research. The second area is citation and attribution of artifacts that are being generated by VOs. In some sense VOs are re-publishing (re-packaging, or generating new synthetic) data and information products. At present only a few VOs address this need and it is clear that a comprehensive solution that includes publishers is required. Our work in VOs and related semantic data framework and integration areas has lead to a view of the next generation of virtual observatories which the two above-mentioned needs as well as others that are emerging. Both of the needs highlight a semantic gap, i.e. that the meaning and use for a user or users beyond the original design intention is very often difficult or impossible to bridge. For example, VOs created for experts with complex, arcane or jargon vocabularies are not accessible to the non-specialist and further, information products the non-specialist may use are not created or considered for creation. In the second case, use of a (possibly virtual) data or information product (e.g. an image or map) as an intellectual artifact that can be accessed as part of the scientific publication and review procedure also introduces terminology gaps, as well as services that VOs may need to provide. Our supposition is that formalized methods in semantics and semantic web

Nuevas relaciones sociales, que acontecen en un espacio nuevo, y que por tanto se desarrollan bajo reglas y motivaciones que desbordan los viejos esquemas de observación.

  14. Grids, Clouds and Virtualization

    Cafaro, Massimo

    2011-01-01

    Research into grid computing has been driven by the need to solve large-scale, increasingly complex problems for scientific applications. Yet the applications of grid computing for business and casual users did not begin to emerge until the development of the concept of cloud computing, fueled by advances in virtualization techniques, coupled with the increased availability of ever-greater Internet bandwidth. The appeal of this new paradigm is mainly based on its simplicity, and the affordable price for seamless access to both computational and storage resources. This timely text/reference int

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

    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

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

    Zeidler, Dana L.

    2016-03-01

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

  8. MIRADA A LA MENTORÍA EN INVESTIGACIÓN DESDE LA PERSPECTIVA SOCIOCULTURAL DE VYGOTSKY.

    Santiago, Nilda G Medina; Rivera, Tania M Cruz; Ortiz, Natalia Jordán

    In this article the authors illustrate the mentoring process through the framework of Vygotsky's sociocultural perspective regarding education and human development. To achieve this goal, they describe their experience as mentor and mentees in a research training mentoring program for undergraduate students. The authors argue that this theoretical and philosophical perspective offers a solid background to mentoring as a real option that contributes to the learning process. They recommend these programs to be encouraged by academic institutions in order for more students and professors to benefit from this process.

    Irina Chelysheva

    2016-12-01

    Full Text Available The articles presents a brief review of basic approaches to media education in Russia from the genesis to present-day conditions of Russian media pedagogy. The historical analysis of media education in Russia has shown that Russian media education tradition relies on several dominant theoretical approaches such as the semiotic, culturological, aesthetic, ethical, sociocultural and critical thinking development conceptions. Contemporary researches focus on studying media culture, various media effects and forms of media addiction, Internet safety and digital competences. Future research prospects of media education in Russia involve further development of scientific media education centers and schools promoting the investigation of urgent theoretical and practical media pedagogy issues.

  10. THE RELEVANCE AND IMPLICATIONS OF VYGOTSKY’S SOCIOCULTURAL THEORY IN THE SECOND LANGUAGE CLASSROOM

    MAMOUR CHOUL TURUK

    2008-11-01

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

  13. Tours in Virtual Globes

    Treves, R.

    2009-12-01

    The most significant new feature to appear in Google Earth 5.0 in February was the tour feature, it can produce eye catching and appealing animations as was shown by the Apollo 11 Tour which shows a model of the lunar module descending to the surface of the moon. It allows users to record themselves navigating around Google Earth switching elements on and off. The use of the tour functionality goes beyond exciting animations, it has important applications as a way of; introducing users to a larger data set presented in a Virtual Globe, offering an alternative to PowerPoint as a platform to support presentations and as a quick way to produce powerful visualizations for education purposes. In this talk I will explore how best to use to tours to present a range of spatial data and examine how the Google Earth tour compares to similar functionality that is appearing in other Virtual Globes and other 3D environments such as Second Life.

  14. Curating Virtual Data Collections

    Lynnes, C.; Ramapriyan, H.; Leon, A.; Tsontos, V. M.; Liu, Z.; Shie, C. L.

    2015-12-01

    NASA's Earth Observing System Data and Information System (EOSDIS) contains a rich set of datasets and related services throughout its many elements. As a result, locating all the EOSDIS data and related resources relevant to particular science theme can be daunting. This is largely because EOSDIS data's organizing principle is affected more by the way they are produced than around the expected end use.Virtual collections oriented around science themes can overcome this by presenting collections of data and related resources that are organized around the user's interest, not around the way the data were produced. Science themes can be: Specific applications (uses) of the data, e.g., landslide prediction Geophysical events (e.g., Hurricane Sandy) A specific science research problem Virtual collections consist of annotated web addresses (URLs) that point to data and related resource addresses, thus avoiding the need to copy all of the relevant data to a single place. These URL addresses can be consumed by a variety of clients, ranging from basic URL downloaders (wget, curl) and web browsers to sophisticated data analysis programs such as the Integrated Data Viewer. Eligible resources include anything accessible via URL: data files: data file URLs data subsets: OPeNDAP, webification or Web Coverage Service URLs data visualizations: Web Map Service data search results: OpenSearch Atom response custom analysis workflows: e.g., Giovanni analysis URL

  15. Virtual Optical Comparator

    Thompson, Greg

    2008-10-20

    The Virtual Optical Comparator, VOC, was conceived as a result of the limitations of conventional optical comparators and vision systems. Piece part designs for mechanisms have started to include precision features on the face of parts that must be viewed using a reflected image rather than a profile shadow. The VOC concept uses a computer generated overlay and a digital camera to measure features on a video screen. The advantage of this system is superior edge detection compared to traditional systems. No vinyl charts are procured or inspected. The part size and expensive fixtures are no longer a concern because of the range of the X-Y table of the Virtual Optical Comparator. Product redesigns require only changes to the CAD image overlays; new vinyl charts are not required. The inspection process is more ergonomic by allowing the operator to view the part sitting at a desk rather than standing over a 30 inch screen. The procurement cost for the VOC will be less than a traditional comparator with a much smaller footprint with less maintenance and energy requirements.

  17. Virtual anthropology meets biomechanics.

    Weber, Gerhard W; Bookstein, Fred L; Strait, David S

    2011-05-17

    A meeting in Vienna in October 2010 brought together researchers using Virtual Anthropology (VA) and Finite Element Analysis (FEA) in order to explore the benefits and problems facing a collaboration between the two fields. FEA is used to test mechanical hypotheses in functional anatomy and VA complements and augments this process by virtue of its tools for acquiring data, for segmenting and preparing virtual specimens, and for generating reconstructions and artificial forms. This represents a critical methodological advance because geometry is one of the crucial inputs of FEA and is often the variable of interest in functional anatomy. However, we currently lack tools that quantitatively relate differences in geometry to differences in stress and strain, or that evaluate the impact on FEA of variation within and between biological samples. Thus, when comparing models of different geometry, we do not currently obtain sufficiently informative answers to questions such as "How different are these models, and in what manner are they different? Are they different in some anatomical regions but not others?" New methodologies must be developed in order to maximize the potential of FEA to address questions in comparative and evolutionary biology. In this paper we review these and other important issues that were raised during our Vienna meeting.

  18. The virtual group identification process: a virtual educational community case.

    Yu, Chia-Ping; Young, Mei-Lein

    2008-02-01

    Because the Internet provides an alternative forum for the social interaction of professional groups, understanding how these groups form as virtual communities (VCs) in cyberspace is crucial. In this study, we observe the social interactions of teachers belonging to the largest VC in Taiwan and analyze discourse on an important educational policy, using content analysis to ascertain how virtual group identity is established. Our primary findings show that among the seven identity categories characterizing professional virtual group identity, both alliance and kinship types of identities are the main forces behind the formation of a virtual group. In contrast, the affection, attachment, bonding, closeness, and nostalgia types of identities show minimal effect. Moreover, leadership of the virtual group plays a critical role in the group setting, and participants play a part in restoring a positive sense of self or in shaping the group identity as they encounter threats in this dynamic environment.

  19. A Virtual Environment Using Virtual Reality and Artificial Neural Network

    Abdul Rahaman Wahab Sait

    2011-12-01

    Full Text Available In this paper we describe a model, which gives a virtual environment to a group of people who uses it. The model is integrated with an Immersible Virtual Reality (IVR design with an Artificial Neural Network (ANN interface which runs on internet. A user who wants to participate in the virtual environment should have the hybrid IVR and ANN model with internet connection. IVR is the advanced technology used in the model to give an experience to the people to feel a virtual environment as a real one and ANN used to give a shape for the characters in the virtual environment (VE. This model actually gives an illusion to the user that as if they are in the real communication environment.

  20. Contact Control, Version 1

    2016-07-21

    The contact control code is a generalized force control scheme meant to interface with a robotic arm being controlled using the Robot Operating System (ROS). The code allows the user to specify a control scheme for each control dimension in a way that many different control task controllers could be built from the same generalized controller. The input to the code includes maximum velocity, maximum force, maximum displacement, and a control law assigned to each direction and the output is a 6 degree of freedom velocity command that is sent to the robot controller.
