    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.

    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)

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

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

    International Nuclear Information System (INIS)

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

    Full Text Available Alexey B Mantsyzov,1 Guillaume Bouvier,2 Nathalie Evrard-Todeschi,1 Gildas 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

    Lapeer, R J

    2005-01-01

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

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

    The present study examined the sociocultural adjustment of 249 sojourning Malaysian undergraduates in Britain. One-hundred and ten Malay and 139 Chinese students enrolled in various courses answered a self-report questionnaire that examined various aspects of sociocultural adjustment and socio-demographics. Overall, Malay students reported significantly poorer sociocultural adjustment than Chinese students, as well as more negative outcomes on a range of predictors. Path analysis for the total sample showed that higher family income led to greater sociocultural adjustment, but partially because it led to more contact with host and conationals, better language proficiency, lower perceived cultural differences and less perceived discrimination. Moreover, participants with higher English proficiency were better adapted, but partially because they perceived less cultural differences as well as having more contact with host nationals. Additionally, individuals reporting better sociocultural adjustment also reported better health statuses. The same model was equally useful at predicting sociocultural adjustment for both Malay and Chinese participants. These results are discussed in terms of the role played by income in buffering against the negative aspects of sociocultural adjustment. PMID:19337675

    2012-12-01

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

  1. Sociocultural determinants of induced abortion

    International Nuclear Information System (INIS)

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

    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.

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

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.

The purpose of this article was to discuss some concepts of the sociocultural approach, changes by which this approach went through last decades, some of their perspectives and authors. The concepts here discussed can be useful in the attempts to articulate psychological investigations in a sociocultural approach. The conclusions point to the need of including the investigations in psychology into a conceptual approach that considers the culture and the social context as central elements, articulating the contributions of the cross-cultural psychology, and of the culture.

  2. A Sociocultural Approach to Recognition and Learning

    Directory of Open Access Journals (Sweden)

    Peter Musaeus

    2006-04-01

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

  3. Socio-cultural determinants of infant malnutrition in Cameroon.

    Science.gov (United States)

    Pemunta, Ngambouk Vitalis; Fubah, Mathias Alubafi

    2015-07-01

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

    Full Text Available I present a sociocultural approach to research and science education that incorporates a recursive relationship between transformation and theory, acknowledges the strengths of subjectivity, and regards difference as a resource for learning. The methodology incorporates hermeneutic-phenomenology, reflexive inquiry, and event-oriented inquiry. Research on emotions contextualizes methodologies for multidisciplinary and multi-level research. Finally, a new journal that was developed as a home for cultural studies of science education is described along with the processes used in manuscript review and publication.

  9. Sociocultural factors in Brazilian neuropsycholinguistic studies

    Directory of Open Access Journals (Sweden)

    Maria Alice de Mattos Pimenta Parente

    2012-12-01

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

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

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

    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

    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.

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

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

In this paper, we describe the concept, implementation and the evaluation are described in various perspective.

  18. Contact problems

    CERN Document Server

    Galin, Lev Aleksandrovich

    2008-01-01

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

  1. Dynamic Virtual Credit Card Numbers

    Science.gov (United States)

    Molloy, Ian; Li, Jiangtao; Li, Ninghui

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

The main purpose of this work is to develop a virtual flow meter wi...

  6. Intelligent virtual interfaces for telerobotics

    Science.gov (United States)

    Grinstein, Georges G.; Maybury, Mark T.; Mitchell, Richard B.

    1992-11-01

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

    Wu, Juan; Cao, Xiaoying; Song, Aiguo

    2003-04-01

    This paper describes a virtual environment system, which can produce dynamic force simulation during the control of objects in virtual environment. A 5 degrees-of-freedom haptic interface master arm with the capability to generate kinesthetic effect is combined in this system. In this system, the human operator manipulates an object in virtual environment by using the 5-DOF master arm. When virtual manipulator contacting with the virtual object, the contact force can be calculated and shown in the graphic interface. The collision response and deformation of the virtual object, which is usually called haptic rendering, also can be exhibited in graph. The experience presents an approach to improve the operator's immersion and can be used in many telerobot control fields.

  1. Virtual Tower

    International Nuclear Information System (INIS)

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

    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.

  5. Modeling socio-cultural processes in network-centric environments

    The major focus in the field of modeling & simulation for network centric environments has been on the physical layer while making simplifications for the human-in-the-loop. However, the human element has a big impact on the capabilities of network centric systems. Taking into account the socio-behavioral aspects of processes such as team building, group decision-making, etc. are critical to realistically modeling and analyzing system performance. Modeling socio-cultural processes is a challenge because of the complexity of the networks, dynamism in the physical and social layers, feedback loops and uncertainty in the modeling data. We propose an overarching framework to represent, model and analyze various socio-cultural processes within network centric environments. The key innovation in our methodology is to simultaneously model the dynamism in both the physical and social layers while providing functional mappings between them. We represent socio-cultural information such as friendships, professional relationships and temperament by leveraging the Culturally Infused Social Network (CISN) framework. The notion of intent is used to relate the underlying socio-cultural factors to observed behavior. We will model intent using Bayesian Knowledge Bases (BKBs), a probabilistic reasoning network, which can represent incomplete and uncertain socio-cultural information. We will leverage previous work on a network performance modeling framework called Network-Centric Operations Performance and Prediction (N-COPP) to incorporate dynamism in various aspects of the physical layer such as node mobility, transmission parameters, etc. We validate our framework by simulating a suitable scenario, incorporating relevant factors and providing analyses of the results.

    2000-12-01

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

    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. PMID:17177103

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

    Directory of Open Access Journals (Sweden)

    KateriMcRae

    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.

The Kazakhs have developed at first glance very complex and many branched kinship bonds with the moral codes, family relationship etiquette, the patterns of rights , duties and responsibilities thus being one of the strongest binding forces. The first and foremost principle of the Kazakh kinship system is the principle of “the seven ancestors”...

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

    2016-01-01

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

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

    Full Text Available In order to rectify environmental degradation, government has encouraged sustainable management among businesses. In addition, researchers have also suggested a new breed of study called “sustainable entrepreneurship”, which links sustainability management to entrepreneurial activities. However, the participation of entrepreneurial firms in sustainability management is still far from satisfactory. Past studies also have found that SMEs are less active in sustainabilty initiatives and many issues related to the intention of firms for sustainability entrepreneurship is still unanswered. Therefore, this study was carried out to examine the influence of socio-cultural factors on intention towards sustainable entrepreneurship among SMEs. A total of 404 SMEs in Malaysia were surveyed by using questionnaire. Based on the statistical analyses performed, this study found that three socio-cultural factors, namely time orientation, sustainability orientation and social norm significantly influenced intention towards sustainable entrepreneurship among SMEs. Thus, in order to develop true sustainable entrepreneurs in the country, the effects of non-economic factors such as socio-cultural factors should not be underestimated. Lastly, some recommendations for future researchers have also been put forth in this paper.

  13. Virtual Cystoscopy

    International Nuclear Information System (INIS)

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

  14. Bonobo habituation in a forest-savanna mosaic habitat: influence of ape species, habitat type, and sociocultural context.

    2015-10-01

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

  15. Haptic feedback for virtual assembly

    1998-12-01

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

    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.

  9. SYSTEMS AND SOCIOCULTURAL APPROACHES TO THE ORIGIN OF LANGUAGE

    Directory of Open Access Journals (Sweden)

    Sukhoverkhov A. V.

    2015-03-01

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

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

    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.

  17. 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...

    Full Text Available Para favorecer una alimentación correcta la orientación alimentaria debe considerar factores socioculturales que condicionen patrones y preferencias del consumo de alimentos propios de cada población. El objetivo de esta investigación fue describir el contexto sociocultural del embarazo y su alimentación en el ámbito doméstico, mediante un enfoque cualitativo. Se realizaron entrevistas en profundidad a 6 mujeres con embarazo de alto riesgo bajo la técnica de saturación de la información. Las entrevistas se transcribieron y analizaron de acuerdo a Bardín con ayuda del programa Atlas TI. Se identificó: incertidumbre por el embarazo no planeado y poco apoyo de la pareja; ciertos cambios en la alimentación para mejorar la salud; percepción de una mala y buena alimentación, aunque ésta no cumplía con las características de una dieta correcta; omisión de la cena y del grupo de verduras y frutas. Las encargadas de preparar y servir los alimentos no siempre fueron las mujeres embarazadas; los alimentos percibidos peligrosos fueron consumidos y los benéficos presentaron consumo escaso. Resaltó la necesidad de capacitar a los profesionales de la salud para considerar al contexto sociocultural en la orientación alimentaria que proporcionen.

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.

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

    Bladder cancer is a common problem facing urologists worldwide. The gold standard for its diagnosis and follow-up is the direct visualization of the tumor using conventional cystoscopy. Despite having high sensitivity and specificity for detecting bladder cancer, conventional cystoscopy is regarded as an invasive procedure which is associated with several complications. In addition, regular follow-up of patients with bladder cancer is a financial burden on the health system. With the progressive development in diagnostic imaging and medical computer software technologies, it was possible to generate virtual reality images to aid the clinician to inspect the interior of the bladder in real time. This technology is considered as a safe test for bladder cancer diagnosis and follow-up, and it is associated with cancer detection rates comparable with conventional cystoscopy. However, it is associated with some drawbacks that limit its use in routine clinical practice at the current time. In this paper, we review the development and clinical applications of this technology. PMID:18598226

    2006-02-23

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

  18. The Socio-Cultural Functions of Kazakh Kinship Terms

    2015-05-01

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

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

    Science.gov (United States)

    Goos, Merrilyn

    2014-09-01

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

    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.

    Murnen, Sarah K; Poinsatte, Katherine; Huntsman, Karen; Goldfarb, Jesse; Glaser, Daniel

    2015-01-01

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

    The main objective of the Virtual Observatory (VO) is to guarantee an easy and efficient access and analysis of the information hosted in astronomical archives. The Spanish Virtual Observatory (SVO) is a project that was born in 2004 with the goal of promoting and coordinating the VO-related activities at national level. SVO is also the national contact point for the international VO initiatives, in particular the International Virtual Observatory Alliance (IVOA) and the Euro-VO project. The project, led by Centro de Astrobiología (INTA-CSIC), is structured around four major topics: a) VO compliance of astronomical archives, b) VO-science, c) VO- and data mining-tools, and d) Education and outreach. In this paper I will describe the most important results obtained by the Spanish Virtual Observatory in its first ten years of life as well as the future lines of work.

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

    In this paper we show that any good toric contact manifold has well defined cylindrical contact homology and describe how it can be combinatorially computed from the associated moment cone. As an application we compute the cylindrical contact homology of a particularly nice family of examples that appear in the work of Gauntlett-Martelli-Sparks-Waldram on Sasaki-Einstein metrics. We show in particular that these give rise to a new infinite family of non-equivalent contact structures on $S^2 \\times S^{3}$ in the unique homotopy class of almost contact structures with vanishing first Chern class.

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

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

    Ernst, Erik; Ostermann, Klaus; Cook, William Randall

    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...

    Renzi, Ronald (90 Arroyo Seco Way, Tracy, San Joaquin County, CA 95376)

    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.

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

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

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

  13. Graded contact manifolds and contact Courant algebroids

    Science.gov (United States)

    Grabowski, Janusz

    2013-06-01

    We develop a systematic approach to contact and Jacobi structures on graded supermanifolds. In this framework, contact structures are interpreted as symplectic principal R×-bundles. Gradings compatible with the R×-action lead to the concept of a graded contact manifold, in particular a linear (more generally, n-linear) contact structure. Linear contact structures are proven to be exactly the canonical contact structures on first jets of line bundles. They provide linear Kirillov (or Jacobi) brackets and give rise to the concept of a Kirillov algebroid, an analog of a Lie algebroid, for which the corresponding cohomology operator is represented not by a vector field (de Rham derivative) but by a first-order differential operator. It is shown that one can view Kirillov or Jacobi brackets as homological Hamiltonians on linear contact manifolds. Contact manifolds of degree 2, as well as contact analogs of Courant algebroids are studied. We define lifting procedures that provide us with constructions of canonical examples of the structures in question.

    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.

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

  4. High availability using virtualization

    International Nuclear Information System (INIS)

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

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

    Energy Technology Data Exchange (ETDEWEB)

    Baldwin, T. E.; Poetsch, R.

    1977-08-01

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

  11. The effect of instruction on socio-cultural beliefs hindering the learning of science

    Science.gov (United States)

    Jegede, Olugbemiro J.; Okebukola, Peter A. O.

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

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

    CERN Document Server

    Duriez, Christian; Kheddar, Abderrahmane; Andriot, Claude

    2008-01-01

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

    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.

    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.

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

  15. Understanding Electronic Medical Record Adoption in the United States: Communication and Sociocultural Perspectives

    Science.gov (United States)

    Kreps, Gary L; Polit, Stan

    2013-01-01

    Background This paper adopts a communication and sociocultural perspective to analyze the factors behind the lag in electronic medical record (EMR) adoption in the United States. Much of the extant research on this topic has emphasized economic factors, particularly, lack of economic incentives, as the primary cause of the delay in EMR adoption. This prompted the Health Information Technology on Economic and Clinical Health Act that allow financial incentives through the Centers of Medicare and Medicaid Services for many health care organizations planning to adopt EMR. However, financial incentives alone have not solved the problem; many new innovations do not diffuse even when offered for free. Thus, this paper underlines the need to consider communication and sociocultural factors to develop a better understanding of the impediments of EMR adoption. Objective The objective of this paper was to develop a holistic understanding of EMR adoption by identifying and analyzing the impact of communication and sociocultural factors that operate at 3 levels: macro (environmental), meso (organizational), and micro (individual). Methods We use the systems approach to focus on the 3 levels (macro, meso, and micro) and developed propositions at each level drawing on the communication and sociocultural perspectives. Results Our analysis resulted in 10 propositions that connect communication and sociocultural aspects with EMR adoption. Conclusions This paper brings perspectives from the social sciences that have largely been missing in the extant literature of health information technology (HIT) adoption. In doing so, it implies how communication and sociocultural factors may complement (and in some instances, reinforce) the impact of economic factors on HIT adoption. PMID:23612390

  3. Virtual Machine Logbook - Enabling virtualization for ATLAS

    International Nuclear Information System (INIS)

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

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

  6. High availability using virtualization

    CERN Document Server

    Calzolari, Federico

    2009-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Victor A. Akujuru

    2014-07-01

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

  14. The virtual Haken conjecture

    CERN Document Server

    Agol, Ian; Manning, Jason

    2012-01-01

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

  15. Twisted virtual biracks and their twisted virtual link invariants

    CERN Document Server

    Ceniceros, Jessica

    2011-01-01

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

  2. Knowledge Value Creation Characteristics of Virtual Teams: A Case Study in the Construction Sector

    Science.gov (United States)

    Vorakulpipat, Chalee; Rezgui, Yacine

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

  11. Electric contact arcing

    International Nuclear Information System (INIS)

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

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

    Science.gov (United States)

    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 highlighted.

    Purpose To explore factors influencing health and health care within the sociocultural context of Cambodian Americans (CAs or Khmers) and Korean Americans (KA) and to examine intergroup similarities and differences between CAs and KAs, focusing on hepatitis B virus (HBV) and liver cancer prevention behaviors. Methods The study used a qualitative design guided by the revised Network Episode Model (NEM) and informed by ethnographic analysis. Focus group interviews with key informants among CA community health leaders (CHLs, n=14) and individual interviews with key informants of KA CHLs (n=9) were audiotaped and transcribed. Results Three categories that influenced HBV and liver cancer prevention emerged from both CAs and KAs: the socio-cultural, individual, and behavioral. Four additional sub-categories (sub-themes) of sociocultural were identified as socio-history, socio-medicine, socio-linguistic, and socio-health resources. Both CAs and KAs, however, have low levels of knowledge and significant misunderstandings about HBV infection. Conclusions The study identifies and compares the social-cultural determinant for HBV and liver cancer and highlights the factors of education, intercultural communication, and interactions within socio-cultural contexts of CA and KA subgroups. In general, conceptual overlaps are apparent between Khmers (from now on, the terms, CA and Khmer, will be used interchangeably) and Koreans except for the sub-theme of socio-history. However, differences in concept-specific attributes point to the need to account for differing conceptualizations and implications of specific ethnic groups’ sociocultural contexts, and to design contextually-relevant outreach and educational interventions for targeted AAPI subgroups.

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

  18. Grasping at 'thin air': multimodal contact cues for reaching and grasping.

    Science.gov (United States)

    Zahariev, Mihaela A; MacKenzie, Christine L

    2007-06-01

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

    2015-08-01

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

    2010-01-01

    An asynchronous, variational method for simulating elastica in complex contact and impact scenarios is developed. Asynchronous Variational Integrators (AVIs) are extended to handle contact forces by associating different time steps to forces instead of to spatial elements. By discretizing a barrier potential by an infinite sum of nested quadratic potentials, these extended AVIs are used to resolve contact while obeying momentum- and energy-conservation laws. A series of two- and three-dimensional examples illustrate the robustness and good energy behavior of the method.

    Full Text Available Despierta gran inters terico y social en nuestros das la identificacin y medida de los factores que contribuyen al desarrollo de alteraciones de la imagen corporal y ms concretamente al desarrollo de la insatisfaccin corporal. El prototipo femenino de belleza dominante desde hace tres dcadas [...] en nuestra cultura propone una delgadez tan extrema que resulta no slo inalcanzable, sino adems muy poco saludable. El ideal masculino de belleza, por otro lado, demanda un cuerpo delgado, pero musculado, y ste ha adquirido gran importancia, por lo que con frecuencia se adoptan, a fin de mejorar la propia imagen, numerosas conductas peligrosas para la salud, como el consumo de esteroides, efedrina y dietas alimentarias dainas. La imagen corporal, conformada por las autopercepciones fsicas de cada persona, ha sido objeto de numerosas investigaciones durante las ltimas dcadas en relacin con rasgos psicolgicos tan importantes como la autoestima, la depresin, la ansiedad o los trastornos alimentarios y, muy en especial, con la insatisfaccin corporal. Est comprobado que, en general, las mujeres manifiestan mayor insatisfaccin corporal que los hombres en todas las pocas de su vida, desde la preadolescencia hasta la tercera edad, si bien las diferencias de sexo en la edad adulta y en la tercera edad son menores que en la adolescencia. Por otro lado, aun cuando la insatisfaccin de las mujeres con su cuerpo tiende a mantenerse estable a lo largo de todo el ciclo vital, es digno de sealar que la importancia conferida a la apariencia fsica y, ms en concreto, al tamao y peso corporal, decrece con la edad. La presin sociocultural percibida aparece como principal causa de la insatisfaccin corporal. Desde el enfoque sociocultural se seala, en concreto, a los medios masivos de comunicacin, al entorno social prximo y a la familia como los tres elementos clave de dicha presin: cuanto ms altos son los niveles de presin percibida con respecto a una imagen corporal idealizada, ms se incrementa la preocupacin por la imagen y por las estrategias de cambio corporal. La investigacin previa ha prestado considerable atencin a las diferencias de sexo y de edad en cuanto a la insatisfaccin corporal, pero se echan en falta: a) conocimientos ms precisos sobre la insatisfaccin corporal de los hombres; b) una perspectiva comparativa de las diferencias de sexo tanto en insatisfaccin corporal como en presin percibida a lo largo de las distintas etapas del ciclo vital; c) mayor informacin sobre las variaciones interpersonales en la relacin entre la insatisfaccin corporal y la presin sociocultural percibida, y d) una mejor comprensin de la naturaleza de las influencias socioculturales. Esta investigacin trata de contribuir a la superacin de estas carencias plantendose las siguientes hiptesis: 1) La insatisfaccin corporal guarda estrecha relacin con la presin sociocultural percibida; 2) las mujeres participantes, en todos los grupos de edad, muestran ms insatisfaccin corporal e indican sentirse ms influidas por factores socioculturales que los hombres; 3) las diferencias de sexo (tanto en insatisfaccin corporal como en presin sociocultural percibida) son mayores en los grupos de menor edad que en los de ms edad; 4) el sexo resulta ser un mejor predictor de la insatisfaccin corporal y de los influjos socioculturales percibidos que la edad. Participaron en el estudio 1259 personas: 627 adolescentes, 271 adultos jvenes, 248 adultos y 112 sujetos mayores de 55 aos, quienes respondieron el Eating Disorders Inventory-2 (EDI-2), de Garner, que permite identificar la insatisfaccin corporal, as como el Cuestionario de Influencias sobre el Modelo Esttico Corporal (CIMEC), de Toro, Salamero y Martnez-Malln. Los resultados obtenidos proporcionan una visin ms completa que la hasta ahora disponible acerca de las relaciones entre la insatisfaccin corporal y la presin sociocultural percibida en las distintas etapas de

    In this paper, a virtual experiment concerning driving on off-roads is investigated via 3D normal vibro-contact problem with friction. The dynamic road concept is introduced in order to characterize a particular stretch of road by total longitudinal, lateral, and normal forces and their geometric distributions in the contact patches. The off-road profiles are built by image sonification technique. The cross-sectional curves of off-roads before and after deformation, the contact between the tire and the road, the distribution of contact and friction forces in the contact domain, the natural frequencies and modes when the tire is in ground contact, are estimated. The approach is exercised on two particular problems and results compare favorably to existing analytical and numerical solutions. The feasibility of image sonification technique is useful to build a low-cost virtual reality environment with an increased degree of realism for driving simulators and higher user flexibility.

  5. Occupational Contact Dermatitis

    2008-06-01

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

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

To accomplish this aim, we carry out a quantitative statistical type of research with the software SPSS 17 (Statistical Product and Service Solutions, in which we apply a descriptive and inferential analysis. The instrument used is a questionnaire and the participants are 59 Bulgarian students who study Spanish as a foreign language in a non-immersion context. The levels of the participants are B1, C1 and C2. It is our purpose to analyse some aspects concerning the sociolinguistic and sociocultural adequacy of students, amongst them the relation between adequacy and level of Spanish of the participants. Likewise, we pay attention to the degree in which the students tend to transfer to the target language and culture patterns pertaining to their own culture. We seek to raise awareness about the importance of intercultural adequacy, because we believe that culture of a foreign language must be taught progressively in all levels. Objectives and contents need to be planned carefully, and the degree of complexity must increase according to the linguistic competence of students, without letting aside other competences.

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

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

    Full Text Available Virtualized environments can make forensics investigation more difficult. Technological advances in virtualization tools essentially make removable media a PC that can be carried around in a pocket or around a neck. Running operating systems and applications this way leaves very little trace on the host system. This paper will explore all the newest methods for virtualized environments and the implications they have on the world of forensics. It will begin by describing and differentiating between software and hardware virtualization. It will then move on to explain the various methods used for server and desktop virtualization. Next, it will explain how virtualization affects the basic forensic process. Finally, it will describe the common methods to find virtualization artifacts and identify virtual activities that affect the examination process of certain virtualized user environments.

  17. Virtual simulation. 117

    International Nuclear Information System (INIS)

    The promise of CT-based radiotherapy treatment design remains largely unfulfilled. There is clearly a variety of reasons for this including cost considerations and physicians' justifiable reluctance to alter standard practice but also, and perhaps most importantly, a broad failure of the community to integrate the CT scanner into the process of treatment design. We are addressing this issue by reshaping the treatment design process and the role of the CT scanner in that process in order to realize the benefit of the additional information the scanner makes available. In particular we believe that a superset of the functions of a conventional treatment simulator can be provided to an acceptable degree of fidelity by a CT scanner, appropriate computer displays, and Computer-Aided Design software. Because it involves the interaction of a virtual simulator (provided by the CAD software) with a virtual patient (defined by CT) we call this process virtual simulation. The primary objective of virtual simulation is to extend the treatment design options available to a radiotherapist, and to provide tools to facilitate rapid understanding and evaluation of those options, by reducing the treatment design process to an intuitive manipulation of simple pictures. We present here the key elements of the virtual simulation system and their relations to their traditional counterparts. We also discuss our prototype implementation of the CAD tool. 8 refs.; 1 figure; 1 table

    Full Text Available The virtual recreation of a physical three dimensional (3D exhibition or museum allows a visitor to navigate in this virtual scenario in a way closer to reality. This issue is particularly relevant when the museum building is by itself a piece of art, as it is often the case. In this paper, the use of virtual 3D models in the domain of cultural diffusion is analysed, considering the common aspects of its application either for collections of museum’s or for buildings and artifacts deteriorated or destroyed along the time. A wide range of applications are presented to exemplify the different requirements and techniques that can be considered in this domain. Techniques to create 3D models are reviewed as they are the base to generate a virtual environment and special attention is given to applications devoted to the development of 3D virtual museum exhibitions.http://dx.doi.org/10.14429/djlit.33.3.4608

    Ellis, Stephen R.

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

  20. Double pendulum contact problem

    Directory of Open Access Journals (Sweden)

    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.

  1. Lettuce contact allergy.

    Science.gov (United States)

    Paulsen, Evy; Andersen, Klaus E

    2016-02-01

    Lettuce (Lactuca sativa L.) and its varieties are important vegetable crops worldwide. They are also well-known, rarely reported, causes of contact allergy. As lettuce allergens and extracts are not commercially available, the allergy may be underdiagnosed. The aims of this article are to present new data on lettuce contact allergy and review the literature. Lettuce is weakly allergenic, and occupational cases are mainly reported. Using aimed patch testing in Compositae-allergic patients, two recent Danish studies showed prevalence rates of positive lettuce reactions of 11% and 22%. The majority of cases are non-occupational, and may partly be caused by cross-reactivity. The sesquiterpene lactone mix seems to be a poor screening agent for lettuce contact allergy, as the prevalence of positive reactions is significantly higher in non-occupationally sensitized patients. Because of the easy degradability of lettuce allergens, it is recommended to patch test with freshly cut lettuce stem and supplement this with Compositae mix. As contact urticaria and protein contact dermatitis may present as dermatitis, it is important to perform prick-to-prick tests, and possibly scratch patch tests as well. Any person who is occupationally exposed to lettuce for longer periods, especially atopics, amateur gardeners, and persons keeping lettuce-eating pets, is potentially at risk of developing lettuce contact allergy.

  2. Numerical algorithms for contact problems in linear elastostatics

    International Nuclear Information System (INIS)

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

    Patients with multiple contact allergies, also referred to as polysensitized, are more frequent than predicted from prevalence of single sensitivities. The understanding of why some people develop multiple contact allergies, and characterization of patients with multiple contact allergies is...... developing multiple contact allergies. Evidence of allergen clusters among polysensitized individuals is also reviewed. The literature supports the idea that patients with multiple contact allergies constitute a special entity within the field of contact allergy. There is no generally accepted definition of...... patients with multiple contact allergies. We suggest that contact allergy to 3 or more allergens are defined as multiple contact allergies....

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

  8. The Virtual Diphoton Excess

    Stolarski, Daniel

    2016-01-01

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

    misunderstandings and a lack of shared meaning between participants. In this paper, we address the complexity of building shared meaning. We examine the communication breakdowns that occurred in two globally distributed virtual teams by providing an analytical distinction of the organizational context as the...... foundation for building shared meaning at three levels. Also we investigate communication breakdowns that can be attributed to differences in lifeworld structures, organizational structures, and work process structures within a virtual team. We find that all communication breakdowns are manifested and...... experienced by the participants at the work process level; however, resolving breakdowns may require critical reflection at other levels. Where previous research argues that face-to-face interaction is an important variable for virtual team performance, our empirical observations reveal that communication...

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

    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.

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

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

    Full Text Available

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

    Sociocultural theory has made a great impact on the learning and teaching profession. The theory advocates learning, including L2 acquisition, as a semiotic process where participation in socially mediated activities is essential. It regards instruction as crucial to L2 development and should be geared to the Zone of Proximal Development (ZPD) that is beyond the learner‟s actual development level. It believes that learning in an L2 context should be a collaborative achievement and not an isol...

    This dissertation focuses on the impact of socio-cultural factors on school engagement of minority students in Dutch secondary schools. This question was raised because studies that focus on the impact of structural or institutional factors were often left with an 'ethnic residual'. This ethnic factor is often post-hoc related to socio-cultural factors without a solid explanation of how such factors impact on school engagement. This dissertation aimed at filling this gap by focusing on the im...

  2. Virtual Displacement in Lagrangian Dynamics

    CERN Document Server

    Ray, S; Ray, Subhankar

    2004-01-01

    The confusion and ambiguity encountered by students, in understanding virtual displacement and virtual work, is addressed in this article. A definition of virtual displacement is presented that allows one to express them explicitly for both time independent and time dependent constraints. It is observed that for time independent constraints the virtual displacements are the displacements allowed by the constraints. However this is not so for a general time dependent case. For simple physical systems, it is shown that, the work done on virtual displacements by the constraint forces is zero in both the situations. For allowed displacements however, this is not always true. It is also demonstrated that when constraint forces do zero work on virtual displacement, as defined here, we have a solvable mechanical problem. We identify this special class of constraints, physically realized and solvable, as the ideal constraints. The concept of virtual displacement and the principle of zero virtual work by constraint fo...

  3. Capital assets and intercultural borderlands: socio-cultural challenges for natural resource management.

    Science.gov (United States)

    Stratford, Elaine; Davidson, Julie

    2002-12-01

    In their design or implementation, many natural resource management (NRM) programs ignore critical socio-cultural dimensions of the challenge to advance sustainability. Building on particular ideas about culture and human ecosystems, we combine the strengths of the capital assets model of sustainability and the idea of intercultural borderlands to respond to this gap. To advance our thesis about the utility of these tools, we critically reviewed and analysed a cross-disciplinary literature relating to the socio-cultural dimensions of NRM. This paper stems from that labour and examines particular tensions that arise in land management as a result of Australians' specific colonial and postcolonial legacies. These tensions--related to ethnicity, gender, population, age and health--are among the threads in the larger tapestry that comprises the socio-cultural dimensions of NRM. For the Australian case, they are central, longstanding and persistent, and thus worthy of analysis; and they are applicable in general terms to other places with similar histories of settlement and land use.

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

    Science.gov (United States)

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    Kjerulf Petersen, L.; Holst Andersen, A.

    2009-02-15

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

  6. 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.

    N. G. Murayeva

    2015-02-01

    Full Text Available The paper deals with the model fostering the socio-cultural competence of the higher school students. The model in question is based on the integration of project activities and Web 2.0 information technologies, the methods facilitating its implementation being described along with the teaching means and forms, and socio-cultural competence formation levels. The author demonstrates the complex of problematic tasks which become more complicated depending on the acquired level of the above competence, and mastered skills and abilities. The tree types of socio-cultural projects are recommended according to the achieved levels: mini-project, web quest and web project. The suggested model fulfills the idea of pedagogic facilitation of the foreign language learning by using the meaning formation mechanism in socio- cultural educational environment. The author argues that its introduction into the higher school training process can promote the students’ interest to the different culture and mentality, and their readiness for the cross-cultural dialog over the internet. 

  8. Understanding the community impact of lymphatic filariasis: a review of the sociocultural literature

    2007-06-01

    Full Text Available Lymphatic filariasis (LF is endemic in approximately 80 tropical and subtropical countries. About 120 million people are infected with the parasite and a billion are estimated to be at risk of infection. The main focus of the LF elimination programme to date has been to interrupt transmission by means of annual community-wide treatment campaigns with diethylcarbamazine and albendazole, or albendazole and ivermectin, for a period of four to six years. Although substantial progress has been recorded wherever the strategy has been successfully implemented, initial gains have been accompanied by a realization that this strategy alone will not ensure a permanent solution in all settings. The fairly extensive LF literature is dominated by laboratory research and quantitative field measurement of the impact of LF, particularly local prevalence studies of parasite-infected humans and vectors. As the global elimination programme expands, the absence of sociocultural understanding is being recognized as a critical flaw in ensuring that programmes are appropriate and responsive to local needs and understanding. This paper assesses the current state of sociocultural understanding pertaining to LF. It concludes that, at present, there is insufficient understanding of the sociocultural factors associated with the presence and treatment of the disease, and that appropriate social science methods should be used to address this deficiency and ensure community partnership in delivering and sustaining the success of LF elimination programmes.

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

    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.

  12. Socio-cultural impacts of large-scale cruise tourism in Souq Mutrah, Sultanate of Oman

    Manuela Gutberlet

    2016-02-01

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

  13. Prolongation on Contact Manifolds

    CERN Document Server

    Eastwood, Michael

    2009-01-01

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

    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. PMID:25000234

  15. Nurturing the Growing Generations Values in the Process of Socio-Cultural Transformation of Society

    2015-02-01

    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 mans 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.
