The Consequences of Mobility : Linguistic and Sociocultural Contact Zones  

DEFF Research Database (Denmark)

The book is an anthology of articles investigating â?? from within four different theoretical and methodological perspectives â?? the kinds of linguistic and sociocultural contacts brought about by internationalization and transnational migrations in the contemporary world. It includes topics such as the following, related to this general interdisciplinary objective: â?¢ Language use in social networks, with special reference to language contact in interpersonal relations and interactions, including codeswitching and other manifestations of the construction of sociocultural identities in face-to-face interaction â?¢ Language contact in society and in the world, and social hierarchies between languages: consequences of (mobility driven) language spread, and the ensuing processes of redefining linguistic differences and identities: language competition, language promotion and language discrimination â?¢ The complex relationship between language and culture: how can we envisage mobility and language spread across cultural areas without conceptualizing language as culturally neutral? (cp. the frequent conceptualization of English as culturally neutral) â?¢ Language contact in the individual: multiple language competencies and the idea of plurilingualism - in Europe and in the world â?¢ The concept of linguaculture/languaculture, and studies related to this concept. â?¢ Language and sociocultural identity: how can we address this issue thinking both of first languages and of languages functioning as second and foreign languages? â?¢ The concepts of first language (mother tongue), second language, foreign language, and lingua franca: how can we develop and refine these analytical concepts taking into consideration the complexities of language contacts and plurilingual competencies?

Characterizing Mobility and Contact Networks in Virtual Worlds  

Science.gov (United States)

Virtual worlds have recently gained wide recognition as an important field of study in Computer Science. In this work we present an analysis of the mobility and interactions among characters in World of Warcraft (WoW) and Second Life based on the contact opportunities extracted from actual user data in each of those domains. We analyze character contacts in terms of their spatial and temporal characteristics, as well as the social network derived from such contacts. Our results show that the contacts observed may be more influenced by the nature of the interactions and goals of the users in each situation than by the intrinsic structure of such worlds. In particular, observations from a city in WoW are closer to those of Second Life than to other areas in WoW itself.

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

Sociocultural approach to textbook  

Directory of Open Access Journals (Sweden)

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

A fixed point proximity method for extended contact manipulation of deformable bodies with pivoted tools in multimodal virtual environments.  

Science.gov (United States)

In the real world, tools used for manipulation are pivoted with specialized tips for specific functions including grasping and cutting. Manipulating deformable virtual objects with them involves maintaining extended contact, which is difficult due to the variations in applied force. Our method consists in selecting a fixed set of points on the jaws of a pivoted tool, and placing them either equidistant or according to the geometry of the tool. Vertex and triangle proximities are calculated for each of the interacting deformable objects for collision detection. This method was successfully tested in a surgical simulation scenario where a deformable omental fat model was grasped and retracted while maintaining full contact with the pivoted tool tip at all times.

Studies on the effect of virtual crosslinking on the hydrolytic stability of novel aliphatic polyurethane ureas for blood contact applications.  

Science.gov (United States)

The effect of virtual crosslinking on the hydrolytic stability of completely aliphatic novel poly(urethane ureas), HFL9-PU1 (hard-segment content 57.5%) and HFL13-PU2 (hard-segment content 67.9%) based on 4,4'-methylene bis(cyclohexyl isocyanate) (H(12)MDI)-hydroxy-terminated polybutadiene-1,6-hexamethylene diamine, was studied. Fourier transform infrared-attenuated total reflectance and wide-angle X-ray diffraction studies revealed hydrogen-bonding interaction and microphase separation and formation of crystallites by short- and long-range ordering in hard-segment domains. Three-dimensional networks from hydrogen bonding in the present polymers lead to virtually crosslinking and insolubility. These polymers were noncytotoxic to L929 fibroblast cells. The hemolytic potential is below the accepted limit. The studies on in vitro biostability in Ringer's solution, phosphate buffered saline, and papain enzyme revealed no weight loss. The infrared spectral studies revealed changes in the surface, especially on HFL9-PU1 aged in Ringer's solution and phosphate buffered saline, and no changes when aged in papain. The marginal changes noticed in tensile properties were attributed to the changes in degree of hydrogen bonding and associated rearrangement of molecular structure in the bulk. The results revealed that the lesser the crosslinking in virgin polymer, the higher the crosslinking in aged polymer and vice versa. Increased crosslinking during aging provided increased tensile properties in the aged polymer over the virgin polymer and vice versa. For comparison, an aliphatic polyetherurethane urea (HFL16-PU3) was also synthesized using poly(oxy tetra methylene glycol) in addition to the above reactants. Though both HFL9-PU1 and HFL16-PU3 contained the same hard-segment content, the aged sample of the latter showed decreased tensile properties with increased crosslinking during aging in contrast to the former. This was attributed to less microphase separation in the virgin HFL16-PU3 polymer. PMID:11309801

A Sociocultural Approach to Recognition and Learning  

Directory of Open Access Journals (Sweden)

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

Sociocultural factors in Brazilian neuropsycholinguistic studies  

Scientific Electronic Library Online (English)

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

La salud pública. Un fenómeno sociocultural complejo  

Directory of Open Access Journals (Sweden)

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

Training Virtually Virtual  

Directory of Open Access Journals (Sweden)

Full Text Available This paper reports from a longitudinal study of a Swedish manufacturer in the automotive industry, where a series of studies have explored the potential and limitations of computer-based training of assembly operators. The study is focusing on two supplementing sets of target variables – operators’ attitudes and the quality output from operators in real production. Starting with small-scale studies where proof-of-concept for virtual training is established, the research moves on to comparative studies where different computer-based learning models are contrasted and evaluated. The research design ends with large-scale field experiments assessing the effects of computer-based training in terms of quality output. The results clearly demonstrate that computer-based training, when integrated with training of standardized work procedures, outperforms traditional methods for operator training, regardless of the content and the context of the assembly operation. The findings of the study are synthesized into a design framework for virtual training where cognitive and craftsmanship training is contrasted to the learning of product, process, sequence and finesse of assembly.

Predictores de la adaptación sociocultural de estudiantes universitarios extranjeros en Argentina / Predictors of socio-cultural adaptation of foreign university students in Argentina  

Scientific Electronic Library Online (English)

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

A sociocultural perspective on mediated activity in third grade science  

Science.gov (United States)

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

The VRML models are more interactive than the QuickTime versions, but special software may need to be downloaded to open them (read the ÃÂHelpÃÂ page for details). Those people using public computers may be limited from fully accessing the resource. Mozilla Firefox users can view the VRML files directly in their browsers by downloading the Cortona extension (http://www.parallelgraphics.com/products/cortona/download/netscape/). This website is an excellent educational resource for all ages. The Virtual Insects home page (http://www.ento.vt.edu/~sharov/3d/3dinsect.html) has a basic explanation of how virtual reality works, including the Virtual Reality Modeling Language. The "Virtual Images" link takes you to a list of insects that can be viewed as 3D digital reconstructions. The image files would make excellent additions to teaching lectures for introductory classes. Visit the "How to Build Virtual Insects" page to read about how the images were created and how the original models were made more biologically accurate.

Regulation of positive and negative emotion: Effects of sociocultural context  

Directory of Open Access Journals (Sweden)

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.

Estrategias de aculturación y adaptación psicológica y sociocultural de estudiantes extranjeros en la Argentina / Acculturation strategies and psychological and sociocultural adaptation of foreign students in Argentina  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish Sobre la base del modelo de Berry se diseñó un estudio que tenía como objetivo analizar las estrategias aculturativas empleadas por un grupo de estudiantes extranjeros que habían migrado para realizar estudios universitarios en la Argentina. Se analizó el grado de éxito alcanzado en la implementació [...] n de dichas estrategias analizando la adaptación psicológica, la sociocultural, la académica, la satisfacción vital y la discriminación percibida. Se tomó en cuenta la perspectiva del migrante y la de los miembros de la cultura huésped. Participaron del estudio dos muestras de estudiantes universitarios (125 estudiantes extranjeros de diferentes carreras universitarias y 121estudiantes universitarios argentinos). Los instrumentos utilizados fueron los siguientes: las formas real e ideal de la Encuesta de Estrategias Aculturativas de Berry (1997), una escala de discriminación percibida y para examinar las medidas de adaptación, se administraron escalas de adaptación sociocultural y de adaptación académica diseñadas ad-hoc y la Escala de Satisfacción con la Vida (Diener, Emmons, Larsen & Griffin, 1985). Los resultados señalan que la estrategia preferida es la integración y la menos utilizada, la de marginalización. Tanto la percepción del migrante como la del estudiante huésped coinciden con respecto al uso de la estrategia aculturativa preferida, coincidiendo las percepciones tanto del propio sujeto en proceso de aculturación como la de los miembros de la cultura receptora. La integración es la estrategia que trae mejores resultados adaptativos. Aquellos que optaron por el estilo integrativo, eran los migrantes que percibían mayor satisfacción con la vida y un mejor ajuste a la vida académica en general. Abstract in english At present the number of foreign university student is one of the largest in modern history. It has been characterized as those who reside voluntarily and temporarily abroad in order to participate in educational exchange with the intention of returning to their country once they have achieved the p [...] urpose of their trip. These kinds of student have been classified as sojourners (temporary residents) and they are people who migrate from one cultural context for a relatively long time (6 months to 5 years). In the last decade Argentina start hosting a large amount of foreign university students, attracted by the language, the favorable economic conditions and the prestige of universities in Latin America. University students have to deal with a psychological phenomenon called acculturation and it is the process of psychological and cultural change resulting from intercultural contact. Adaptation to this event can be either psychological or cultural. The psychological is related to the well-being experienced as a result of cultural contact. Cultural adaptation involves the implementation of social skills needed to function effectively within a complex cultural environment. Based on acculturation Berry´s model a study was designed to test the acculturative strategies applied by a group of foreign students who had migrated to carry on university studies in Argentina. Berry propose two separate dimensions: (1) immigrants feel their cultural identity and customs as valuable enough to keep them in the host society (maintenance) and (2) relationships with other people or groups in society are truly valuable to identified and encouraged (participation). These dimensions lead to four acculturation strategies. (a) Integration: the migrant try to maintain their cultural heritage and also maintains contact with the dominant cultural group. (b) Assimilation: the individual does not retain their native culture and attempts to maintain contact only with dominant culture members. (c) Marginalization: occurs when the migrant has no interest or ability to pursue their native culture and it is unlikely to come into contact with the host culture. (d) Separation: this occurs when the migrant is able to maintain

Dynamic Virtual Credit Card Numbers  

Science.gov (United States)

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.

Contact lens correction of presbyopia.  

Science.gov (United States)

The ageing population highlights the need to provide effective optical solutions for presbyopic contact lens wearers. However, data gathered from annual contact lens fitting surveys demonstrate that fewer than 40% of contact lens wearers over 45 years of age (virtually all of whom can be presumed to suffer a partial or complete loss of accommodation) are prescribed a presbyopic correction. Furthermore, monovision is prescribed as frequently as multifocal lenses. These observations suggest that an optimal solution to the contact lens correction of presbyopia remains elusive.

Full Text Available This paper is based on evaluating tourism development in Cyprus, a European nation, and its impacts on the socio-cultural structure of the island. The principal concern of this research is aid in sustaining the resource base on which the tourism development in Cyprus depends on. The paper concludes that in spite of all the negative and positive impacts of tourism on Cyprus it is not yet clear whether the benefits outweigh the costs. The reason for this uncertainty is that most of the research is done on an estimate as there is no empirical data available as yet to support either side of the equation.

Human tooth bank: sociocultural profile of a group of donors  

Directory of Open Access Journals (Sweden)

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

Socio-cultural acceptability of cadaver Transplantation in Iran  

Directory of Open Access Journals (Sweden)

Full Text Available Organ transplantation is known to be a new and innovative treatment for patients with progressive organ failures. The present study investigates the current status of transplantation from cadaver along with its socio-cultural acceptability in Iran. The present study is a descriptive research in a systematic review method. Here, by investigating previously conducted researches in Iran during the period 2002-2010, the status of transplantation from cadaver and its socio-cultural acceptability in Iran has been investigated. To collect the data, the access to Iranmedex website, the premier medical data center in Iran, was made possible using the related keywords. The obtained data indicate whereas there is an increase in the number of organ donations from cadaver, it is still low in comparison to other countries. The lack of consent from families of brain-dead patients is a major hurdle on the way of organ transplantation in Iran. In the cases of willingness to donate organs, the major effective factors were the deceased’s religious beliefs and prior tendency. In 66% of the cases, the donors’ families deemed organ donation phenomenon effective in alleviating the sorrow after the death of their beloved ones. The number of organ donation from cadaver in Iran is low contrary to other countries. It seems that general instructions to raise the knowledge on the subject and lay the foundation to increase the tendency towards posthumous organ donation are necessary.

Virtual 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.

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 colon Abstract in english Since 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

Creating opportunities to learn in mathematics education: a sociocultural perspective  

Science.gov (United States)

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

Exploring complex sociocultural situations through soft operational research  

Directory of Open Access Journals (Sweden)

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

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

Socio-Cultural Approaches to Tourism: A Research on the “Tourist” Notion of Young Turkish People  

Directory of Open Access Journals (Sweden)

Full Text Available Significance of tourism sector in Turkey is constantly expanding. Correspondingly the importance of the economic and socio-cultural impact of tourism also continues to develop. Because tourism draws tourists get into closer contact with the locals it has positive and negative effects on the destination. In general the aim of tourists is satisfying their expectations at the maximum degree during their stay. On the other side locals who live and work in the destination region have a primary role in welcoming them and satisfying the tourists’ needs and expectation. Turkish society is particularly well known for many generations as being very hospitable. Current research aims to reveal whether the young Turkish people sustain traditional “Turkish Hospitality” and to see their thoughts about tourists. The field research has been conducted on students of a foundation university located in Izmir and these young people’s point of view on tourists has been investigated by face to face interviews. It has been concluded that there is a weakening trend, nevertheless the notion of hospitality remains.

Virtual teams and legal compliance  

Energy Technology Data Exchange (ETDEWEB)

The production and consumption of manufactured goods across regions and markets has reached a new level of complexity. At a time when products are designed in one region, manufactured in another, and then sold throughout the world, issues of environmental compliance and risk management have become critical design considerations. Product-oriented regulations are being implemented at a rapid rate with substantial implications for design. This is presenting significant challenges for those companies eager to maintain high levels of corporate responsibility and low levels of environmental risk and impact. Through productive collaboration with industry associations and specialist consultants, ESHconnect has successfully developed a suite of web-based tools that inform and resource companies and their product developers. Our content and methodologies help ensure that EcoDesign becomes a robust business process that maximizes trouble-free market access. This necessarily demands an intimate knowledge of regulations that might impact on new products and their life cycle performance. Mindful of cultural factors, legislative complexity and differing time zones, our approach involves personnel based in multiple locations around the world coming together as virtual teams to build, and deliver value-added knowledge covering EcoDesign, Product Stewardship, hazardous wastes, restricted substances, energy efficiency and environmental labelling. The paper describes the process and experiences of establishing a global ecodesign compliance system, including the inherent socio-cultural factors, which can determine success or failure. (orig.)

Virtual Laboratories  

CERN Document Server

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...

Panoramic photographs that immerse their audience in a landscape have been in vogue throughout the history of photographic enterprises. With this in mind, users should not be surprised to learn of the existence of the Virtual Sweden website. Established by Jonas Carlson in 2003, the site contains 360 degree panoramic images taken by Carlson from a wide variety of locales across the globe. Of course, visitors should start by looking at the panoramic photograph taken from the Gronskar lighthouse in the Stockholm archipelago, but then they would be remiss not to look at some of the other available images. Some of the other places Carlson has seen fit to document are Rome, Thailand, Egypt, and London. Visitors can peruse a thematic list of these locations, or they may simply go straight to his "Latest additions" list, which is also on the site's homepage.

Virtual World Astrosociology  

Science.gov (United States)

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

Sociocultural status and incidence of marital violence in Hispanic families.  

Science.gov (United States)

It is not clear whether traditional cultural ideology influences wife assaults in Hispanic-American families, or if culture is confounded with the stresses of poverty, unemployment, and immigration status. Our 1992 study of 1,970 families, including a national oversample of Hispanic families, examines the incidence of marital violence in the three major Hispanic-American subgroups and in Anglo-American families, and considers how sociocultural status and attitudes towards violence affect wife assaults differentially. The findings show that Hispanic Americans, as a whole, do not differ significantly from Anglo Americans in their odds of wife assaults when norms regarding violence approval, age, and economic stressors are held constant. At the same time, considerable heterogeneity was apparent among ethnic subgroups on a number of measures. We also found that being born in the United States increases the risk of wife assaults by Mexican- and Puerto Rican- American husbands. However, the presence of norms sanctioning wife assaults within any group, regardless of socioeconomic status, is a risk factor for wife abuse. PMID:7647043

Sociocultural patterning of neural activity during self-reflection.  

Science.gov (United States)

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

Religion as dialogical resource: a socio-cultural approach.  

Science.gov (United States)

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

Socio-cultural sustainability of pig production: Citizen perceptions in the Netherlands and Denmark  

DEFF Research Database (Denmark)

Many sustainability studies of animal production consider three pillars: the economic, environmental and socio-cultural. Farmers and animal scientists tend to put most emphasis on the economic and environmental pillar and largely ignore the socio-cultural pillar. Socio-cultural sustainability refers to social perceptions of animal farming, including social appreciations and concerns of animal production systems. Integration of social demands and values in the production sector is a prerequisite to justify animal production within a society. The objective of the present study was therefore to gain further insights into socio-cultural sustainability of pig production. Many citizens may not know what contemporary pig production actually entails. To give people a real life experience with pig production, we conducted farm visits with citizen panels with 18 respondents in the Netherlands and 8 respondents in Denmark. In both countries, respondents were divided over two panels and each panel visited a conventional and an organic pig farm. During the farm visits respondents noted their sensory experiences â?? what do you smell, hear, see and feel? In addition, each respondent made pictures of six positive and six negative aspects on the farms for which they had to write a motivation. The qualitative analysis resulted in seven socio-cultural themes (SCT) of pig production namely: 1) meat production, 2) farm activities, 3) farm income, 4) animals, 5) housing system, 6) environment and nature, and 7) culture and landscape. Each SCT included several socio-cultural aspects (appreciations, SCA) and socio-cultural issues (concerns, SCI). We identified 31 SCAs in the Netherlands and 33 SCAs in Denmark, of which 29 were SCIs in both countries. Although many issues were associated with animal welfare, the results also showed that social concerns of pig production extended beyond animal welfare. In general it can be stated that citizens are strongly concerned about overexploitation of animals in contemporary pig production systems, but at the same time they appreciate the dynamism in a pig farm including certain modern developments.

Drive for muscularity and disordered eating among French adolescent boys: a sociocultural model.  

Science.gov (United States)

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

The Influence of Socio-Cultural Background and Product Value in Usability Testing  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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 mac...

Physical priors in virtual colonoscopy  

Science.gov (United States)

Electronic colon cleansing (ECC) aims to remove the contrast agent from the CT abdominal images so that a virtual model of the colon can be constructed. Virtual colonoscopy requires either liquid or solid preparation of the colon before CT imaging. This paper has two parts to address ECC in both preparation methods. In the first part, meniscus removal in the liquid preparation is studied. The meniscus is the curve seen at the top of a liquid in response to its container. Left on the colon wall, the meniscus can decrease the sensitivity and specificity of virtual colonoscopy. We state the differential equation that governs the profile of the meniscus and propose an algorithm for calculating the boundary of the contrast agent. We compute the surface tension of the liquid-colon wall contact using in-vivo CT data. Our results show that the surface tension can be estimated with an acceptable degree of uncertainty. Such an estimate, along with the meniscus profile differential equation will be used as an a priori knowledge to aid meniscus segmentation. In the second part, we study ECC in solid preparation of colon. Since the colon is pressurized with air before acquisition of the CT images, a prior on the shape of the colon wall can be obtained. We present such prior and investigate it using patient data. We show the shape prior is held in certain parts of the colon and propose a method that uses this prior to ease pseudoenhancement correction.

Refletindo sobre a Provinha Brasil a partir das dimensões sociocultural, linguística e cognitiva da leitura / Thinking through Provinha Brasil from the sociocultural, linguistic, and cognitive dimensions of reading  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Este artigo propõe-se a interpretar como a leitura, em suas dimensões sociocultural, linguística e cognitiva (CERUTTI-RIZZATTI, 2009), está contemplada na avaliação nacional padronizada da alfabetização, a Provinha Brasil, em sua primeira edição do ano de 2009. Para tanto, são traçadas algumas refle [...] xões a partir de documentos norteadores da ação pedagógica tanto federais (BRASIL, 2007) quanto municipais (SECRETARIA MUNICIPAL DE EDUCAÇÃO, 2000, 2007), dos Guias que acompanham o kit da Provinha e dos resultados obtidos nessa avaliação por cinco turmas de 2º ano de uma escola pública, municipal, da grande Florianópolis. As questões da Provinha foram classificadas em dois grandes grupos (questões focadas nas habilidades de decodificação e aquelas envolvendo textualização) e são discutidas individualmente, aliando discussão teórica (conceitos pertinentes à alfabetização e letramento) com os resultados apresentados pelos alunos. Como principal conclusão, observa-se que essa edição da Provinha Brasil foca principalmente as dimensões linguística e cognitiva da leitura, em detrimento da dimensão sociocultural. Abstract in english The aim of this study is to analyze the extent to which reading, in its sociocultural, linguistic, and cognitive dimensions (CERUTTI-RIZZATTI, 2009), was taken into account in the first 2009 edition of the literacy standardized national assessment test, Provinha Brazil. To accomplish this goal, it d [...] raws on both the documents that guide the pedagogical action - both national (BRASIL, 2007) and municipal (SÃO JOSÉ, 2000, 2007) - specified in the Guide Manuals included in the Provinha kit and the results of this assessment for five 2nd-year classes of a municipal school in Grande Florianópolis. The Provinha questions were classified into two major groups (decoding skills and textualization) and discussed individually, merging theoretical discussions on literacy with the results achieved by the students. The conclusion stresses that Provinha Brasil is biased towards the linguistic and cognitive dimensions of reading to the detriment of its sociocultural dimension.

A Virtual Class Calculus  

DEFF Research Database (Denmark)

Virtual classes are class-valued attributes of objects. Like virtual methods, virtual classes are defined in an object's class and may be redefined within subclasses. They resemble inner classes, which are also defined within a class, but virtual classes are accessed through object instances, not as static components of a class. When used as types, virtual classes depend upon object identity - each object instance introduces a new family of virtual class types. Virtual classes support large scale program composition techniques, including higher-order hierarchies and family polymorphism. The original definition of virtual classes in BETA left open the question of static type safety, since some type errors were not caught until runtime. Later the languages Caesar and gbeta have used a more strict static analysis in order to ensure static type safety. However, the existence of a sound, statically typed model for virtual classes has been a long-standing open question. This paper presents a virtual class calculus,vc, that captures the essence of virtual classes in these full-fledged programming languages. The key contributions of the paper are a formalization of the dynamic and static semantics of vc and a proof of the soundness of vc.

Virtual World Security Inspection  

Directory of Open Access Journals (Sweden)

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.

Socio-cultural factors influencing prevention and treatment of tuberculosis in immigrant and Aboriginal communities in Canada.  

Science.gov (United States)

This multi-method study used a participatory action research approach to examine the complex net of socio-cultural factors that influenced behaviour related to tuberculosis (TB) prevention and treatment in the 10 highest risk cultural groups consisting of immigrant and Aboriginal populations in the province of Alberta, Canada. Trained community research associates collected qualitative interview data and helped with interpretation and evaluation. A community advisory committee established foundation principles and monitored the ethical and cultural appropriateness of the research process. A key finding is that although patients with active disease learn about TB from health professionals, people in high-risk populations need to learn more about TB transmission and prevention prior to contact. This is particularly important given that lack of knowledge of TB was strongly associated with negative attitudes towards TB and a worse experience of the disease. The study results underline the need for accessible and culturally appropriate health education about TB in the high risk groups. This can be accomplished in collaboration with lay people, particularly those who have recovered from active TB, their family members and health workers from the community. PMID:15896894

The Siemens virtual wedge.  

Science.gov (United States)

A Siemens Virtual Wedge has recently been installed and commissioned at the Northeastern Ontario Regional Cancer Centre. Measurements reported below show that 1) Virtual Wedge factors are within 1.5% of 1; 2) percentage depth doses down to 15 cm for open and virtually wedged fields are identical to within 0.7%; 3) relative cross beam profiles for 60 degrees virtual and physical wedges are very similar except at the toe end where a 5% difference in relative dose has been observed and 4) the peripheral dose from the 60 degrees Virtual Wedge is about half of that from the 60 degrees physical wedge. A clinical protocol requiring combined open and 60 degrees wedged fields has been developed and validated. This protocol, which does not impair the utility of the Virtual Wedge, facilitates the use of on-line portal imaging and significantly reduces the effort required to commission the system.

Virtual reality exposure therapy.  

Science.gov (United States)

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

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.

EDITORIAL: Close contact Close contact  

Science.gov (United States)

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.

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

Scientific Electronic Library Online (English)

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

[Jellinek's developmental stages and their reality under our sociocultural conditions].  

Science.gov (United States)

In a group of 250 hospitalized male patients with the diagnosis 303 the author tested the aptness of Jellinek's developmental stages of alcoholism which are widely used in Czechoslovak alcohology. It was demonstrated that the developmental stages are not integrated developmental stages, that they lack the necessary compactness in the chronological sequence and in the frequency of individual phenomena. Loss of control (8) in the reported form is closer to the onset of development and the frequency of palimpsests (7) develops later, usually is overlaps with prolonged drunkedness (31). At the onset of development dominates "non-adaptive" drinking evaluated frequently as loss of control and in the more advanced stage the constant incidence of palimpsests causes frequent intoxication and declining tolerance. Among individual phenomena the following are important: in stage I regular contact with the drug (04) and increased tolerance (05), in stage II secret drinking (2) and frequency of palimpsests (7), in stage III signs derived mostly from rationalization and alcohol-centered behaviour and finally in stage IV impaired thinking (33), reduced tolerance (37) and possible ethic degradation (32). As to different developmental stages the chronic stage sounds most convincing. PMID:2225186

Virtual Organizations: Beyond Network Organization  

Directory of Open Access Journals (Sweden)

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

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.

Reality in Virtual Learning : Challenges without the Classroom  

DEFF Research Database (Denmark)

The development of ITC has increased focus onto distance learning programs worldwide. Most universities today offer distance learning programs that are based on the Internet. This development represents a fundamental change in the very logic of being a university. It is no longer enough to rely on professor authority. How can one create a learning situation that enables the university to remain viable? In most western countries, the professors have dominated the learning processes at universities. Since the 50s, learning has been about learning-in, memorizing, and cram (Illeris, 2000) where professors most often decide what and when one could learn by providing the context and substance. In this perspective, the student has a role which is close to the one of a passive receiver, and s/he is mainly preoccupied with the problem of generating substance in memory most efficiently. Today, technology challenges our pedagogical reasoning in many ways. However, old pedagogical models often prevail. We see practices where lectures, notes and course information are published on the Internet, where ICT helps professor-student communication, and online based student tests. These attempts are based on old-time educational logic. There are fewer attempts to use ICT according to a different pedagogical perspective than the old professor authoritarian model. The purpose of this paper is to illuminate some challenges virtual students experience when facing a new ICT-based learning situation. We will try to explore and develop understandings of what it might mean to be a student when learning occurs within a virtual problem based learning landscape. When students are used to the traditional classroom, challenges appear in the twilight zone between two pedagogical practices. How do the students cope with challenges that a new virtual program demands, and what paradoxes and ambiguities appear when old learning processes do not work anymore? The present focus reflects an existential-phenomenological point of departure. This perspective is based on the philosophical writings of Søren Kierkegaard and Martin Heidegger (1927/1996; "Being and Time"), and the successors Hans-Georg Gadamer and Paul Ricoeur. The work is also inspired of the father of culturalism - Jerome Bruner (1996) and Wenger's (1998) community of practice. Thompson (1997) is an inspiration through his initiator of hermeneutical endeavor within consumer research. The consequences of this perspective are that the student and his/her experiences and learning cannot be separated from the student's existence. As for the subject matter, we cannot separate the student from his/her studying. Learning becomes a profoundly socio-cultural process which has to be studied according to the situation and context in which it appears. It is the heart of this project that the twilight zone between cultural roles might reveal some interesting knowledge about the introduction of ICT and its consequences. The socio-cultural conditions of present society set the context for the hermeneutic analysis of meanings and salient life concerns that learning experiences hold for time-pressured virtual students with high degree of responsibilities. An existential-phenomenological assumption is that individuals would tend to interpret their experiences within present socio-cultural framework. Due to its novel characteristics of the program, however, it is particularly interesting to investigate the role that virtual studying serves in the construction of reality and meaning. Furthermore, as it is assumed that experiences cannot be separated from who one is (being-in-the world), the process of human change during virtual studying is also expected to influence salient types of learning, the student's work practice, and his/her private practice.

Virtual articulator for the analysis of dental occlusion: An update  

Science.gov (United States)

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

Cultural products and their implications for business models : Why science fiction needs socio-cultural fiction  

DEFF Research Database (Denmark)

Science fiction prototypes (SF prototypes), narratives based on science and technology, havebeenidentifiedas ameans todevelopnew products, services, andbusinessmodels in light of their potential of enhancing creativity. Drawing on various fields of theory and examples of innovations derived from the arts, this article argues that the value of SF prototypes can be extended by complementing them with socio-cultural fiction (SCF) prototypes. This links the technological perspective to socio-cultural innovation. Further, while referring to prototypes derived from cultural products, it can be assumed thatthese prototypes through the processes of diffusion and normalization have become part ofthe world of the customer which then can be addressed through new products or services.

Ramadan Fasting and Competitive Sports: Psychological Adaptation within Socio-cultural Context  

Directory of Open Access Journals (Sweden)

Full Text Available The article examines the influence of socio-cultural practices of Ramadan fasting in competitive sports and adaptation pathway of the athletes. The study describes how the socio-cultural context acts as the social “panopticon” and explains the adaptation pathways among Muslim archers. Foucauldian concept explains individual actions and behaviors within social and cultural settings, and adaptation pathways during Ramadan fasting. Eleven elite Malaysian Muslim archers participated in an open ended interview to identify individual experiences of competing in high level sports while engaging in Ramadan fasting. Relevant quotes were extracted to identify means and methods leading to a pathway toward adaptation. The inductively identified pathway viz. understanding of the context, control and adjustment, willpower and self enhancement, belonging and gravitating, trust and support culminates in the dimension of adaptation. The study highlights how cultural and societal influences have a bearing on actions, behaviors, and decisions of competitive athletes.

Trust in Virtual Universities  

Directory of Open Access Journals (Sweden)

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

Body dissatisfaction and perceived sociocultural pressures: gender and age differences / Insatisfacción corporal y presión sociocultural percibida: diferencias asociadas al sexo y a la edad  

Scientific Electronic Library Online (English)

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

The virtual Haken conjecture  

CERN Document Server

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".

Differences in sociocultural environment perceptions associated with gender in science classrooms  

Science.gov (United States)

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

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

Science.gov (United States)

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

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

Energy Technology Data Exchange (ETDEWEB)

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.

Twisted virtual biracks and their twisted virtual link invariants  

CERN Document Server

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.

Virtual Class Support at the Virtual Machine Level  

DEFF Research Database (Denmark)

This paper describes how virtual classes can be supported in a virtual machine.  Main-stream virtual machines such as the Java Virtual Machine and the .NET platform dominate the world today, and many languages are being executed on these virtual machines even though their embodied design choices conflict with the design choices of the virtual machine.  For instance, there is a non-trivial mismatch between the main-stream virtual machines mentioned above and dynamically typed languages.  One language concept that creates an even greater mismatch is virtual classes, in particular because fully general support for virtual classes requires generation of new classes at run-time by mixin composition.  Languages like CaesarJ and ObjectTeams can express virtual classes restricted to the subset that does not require run-time generation of classes, because of the restrictions imposed by the Java Virtual Machine. We have chosen to support virtual classes by implementing a specialized virtual machine, and this paper describes how this virtual machine supports virtual classes with full generality.

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

Science.gov (United States)

The future of dental practice is closely linked to the utilization of computer-based technology, specifically virtual reality, which allows the dental surgeon to simulate true life situations in patients. The virtual articulator has been designed for the exhaustive analysis of static and dynamic occlusion, with the purpose of substituting mechanical articulators and avoiding their errors. These tools will help both odontologists and dental prosthetists to provide the best individualized treatment for each patient. The present review analyzes the studies published in the literature on the design, functioning and applications of virtual articulators. A Medline-PubMed search was made of dental journals, with the identification of 137 articles, of which 16 were finally selected. The virtual articulator can simulate the specific masticatory movement of the patient. During mandibular animation, the program calculates the sites where the opposing teeth come into contact. The studies made to assess the reliability of the virtual articulator show good correspondence in visualization of the number and position of the dynamic contacts. The virtual articulator is a precise tool for the full analysis of occlusion in a real patient. PMID:22157663

Graded contact manifolds and contact Courant algebroids  

Science.gov (United States)

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.

Dynamics of the Molten Contact Line  

Science.gov (United States)

In contrast to the ordinary contact line problem, virtually no information is available on the similar problem associated with a molten material spreading on a solid which is below the melt's fusion point. The latter is a more complex problem which heat transfer and solidification take place simultaneously with spreading, and requires answers not only for the hot melt's advance speed over the cold solid as a function of contact angle, but also for how one is to predict the point of the molten contact line's arrest by freezing. This issues are of importance in evolving methods of materials processing. The purpose of our work is to develop, based on both experiments and theory, an understanding of the dynamic processes that occur when a molten droplet touches a subcooled solid, spreads partly over it by capillary action, and freezes. We seek answers to the following basic questions. First, what is the relationship between the melt's contact line speed and the apparent (dynamic) contact angle? Secondly, at what point will the contact line modon be arrested by freezing? The talk will describe three components of our work: (1) deposition experiments with small molten droplets; (2) investigation of the dynamics of the molten contact line by means of a novel forced spreading method; and (3) an attempt to provide a theoretical framework for answering the basic questions posed above.

Virtual memory management  

Energy Technology Data Exchange (ETDEWEB)

This thesis studies methods of scheduling, memory management, and load control in a virtual memory computer system. It also studies the problem of modeling virtual memory systems. The work contributes new ideas and techniques in each of these areas. Finally, the thesis compares the two alternative classes - local and global - of virtual memory management policies. In the area of scheduling, a multi-level, load-balancing queue is described; this mechanism is useful for maintaining good response time in interactive systems and for managing a central server in a distributed computer system. In the area of memory management, a new policy, WSClock, is developed; this policy combines the natural load control of the WS (working set) policy and the simplicity and low cost of the Clock (approximate global LRU) policy.

The virtual wind tunnel  

Science.gov (United States)

Consideration is given to the design and implementaion of a virtual environment linked to a graphics workstation for the visualization of complex fluid flows. The user wears a stereo head-tracked display which displays 3D information and an instrumented glove to intuitively position flow-visualization tools. The idea is to create for the user an illusion that he or she is actually in the flow manipulating visualization tools. The user's presence does not disturb the flow so that sensitive flow areas can be easily investigated. The flow is precomputed and can be investigated at any length scale and with control over time. Particular attention is given to the visualization structures and their interfaces in the virtual environment, hardware and software, and the performance of the virtual wind tunnel using flow past a tapered cylinder as an example.

A Socio-Cultural Model Based on Empirical Data of Cultural and Social Relationship  

DEFF Research Database (Denmark)

The goal of this paper is to integrate culture and social relationship as a computational term in an embodied conversational agent system by employing empirical and theoretical approach. We propose a parameter-based model that predicts nonverbal expressions appropriate for specific cultures in different social relationship. So, first, we introduce the theories of social and cultural characteristics. Then, we did corpus analysis of human interaction of two cultures in two different social situations and extracted empirical data and finally, by integrating socio-cultural characteristics with empirical data, we establish a parameterized network model that generates culture specific non-verbal expressions in different social relationships.

Obeying God? Obeying Paul? Bridging the socio-cultural context in the interpretation of Biblical imperatives  

Digital Repository Infrastructure Vision for European Research (DRIVER)

When do we encounter God in the Pauline imperatives, or when is it Paul, the man of his times, that we are dealing with? This article develops a model to help us determine the reach of the imperatives into our socio-cultural context today. The imperatives are shown to be more than ad hoc injunctions but, rather, legitimate expressions of the new symbolic world in which both Paul and believers participate by faith. The imperatives carry an illocutionary force which relies on such a shared symb...

Perfectionism in Body Dissatisfaction, Sociocultural Influence of the Thinness model and Symptoms of Eating Disorders  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this study was to assess if perfectionism components explained body dissatisfaction (BD, sociocultural influences of aesthetic model (SIAM and symptoms of eating disorders (ED. The sample comprised 30 women with Bulimia Nervosa (BN, 35 women with Eating Disorder not Otherwise Specified (EDNOS and 63 women without ED. A regression analysis showed that concern over mistakes (CM and doubt about actions explained BD and SIAM in the BN sample; while concern over mistakes only explained SIAM in the EDNOS sample. These findings evidence that two perfectionism components contribute to vulnerability of thinness ideal and BD among women, which constitute two important risk factors for ED.

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

Directory of Open Access Journals (Sweden)

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

On normal contact pairs  

CERN Document Server

We consider manifolds endowed with a contact pair and an additional field of endomorphisms, in the same spirit of almost contact geometry. To such structures is naturally associated an almost complex structure which allows us to define normal contact pairs. Then we use flat bundles to generalize Morimoto's Theorem on product of almost contact manifolds and we construct some examples on Boothby--Wang fibrations over contact-symplectic manifolds. In particular, we obtain new constructions of complex manifolds.

A VIRTUAL OPERATING SYSTEM  

Energy Technology Data Exchange (ETDEWEB)

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

Real-time control of an interactive impulsive virtual prosthesis.  

Science.gov (United States)

An interactive virtual dynamic environment for testing control strategies for neural machine interfacing with artificial limbs offers several advantages. The virtual environment is low-cost, easily configured, and offers a wealth of data for post-hoc analysis compared with real physical prostheses and robots. For use with prosthetics and research involving amputee subjects it allows the valuable time with the subject to be spent in experiments rather than fixing hardware issues. The usefulness of the virtual environment increases as the realism of the environment increases. Most tasks performed with limbs require interactions with objects in the environment. To simulate these tasks the dynamics of frictional contact, in addition to inertial limb dynamics must be modeled. Here, subjects demonstrate real-time control of an eight degree-of-freedom virtual prosthesis while performing an interactive box-and-blocks task. With practice, four nonamputee subjects and one shoulder disarticulation subject were able to successfully transfer blocks in the virtual environment at an average rate of just under two blocks per minute. The virtual environment is configurable in terms of the virtual arm design, control strategy, and task. PMID:23996579

Performance of redirected walking algorithms in a constrained virtual world.  

Science.gov (United States)

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

Metal–nanocarbon contacts  

Science.gov (United States)

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

Fortalezas familiares program: building sociocultural and family strengths in latina women with depression and their families.  

Science.gov (United States)

The purpose of this article is to describe Fortalezas Familiares (FF; Family Strengths), a community-based prevention program designed to address relational family processes and promote well-being among Latino families when a mother has depression. Although depression in Latina women is becoming increasingly recognized, risk and protective mechanisms associated with children's outcomes when a mother has depression are not well understood for Latino families. We begin by reviewing the literature on risk and protective psychosocial mechanisms by which maternal depression may affect Latino youth, using family systems theory and a developmental psychopathology framework with an emphasis on sociocultural factors shaping family processes. Next, we describe the theoretical basis and development of the FF program, a community-based 12-week intervention for Latina immigrant women with depression, other caregivers, and their children. Throughout this article, we use a case study to illustrate a Latina mother's vulnerability to depression and the family's response to the FF program. Recommendations for future research and practice include consideration of sociocultural processes in shaping both outcomes of Latino families and their response to interventions. PMID:24033237

Personal equations: reflections on the history of fieldwork, with special reference to sociocultural anthropology.  

Science.gov (United States)

In the latter part of the nineteenth century, diverse sciences grounded in natural history made a virtue of field research that somehow tested scientists' endurance; disciplinary change derived from the premise that witnesses were made reliable by character-molding trials. The turn to the field was a function of structural transformations in various quarters, including (but hardly limited to) global politics, communications systems, and scientific institutions, and it conduced to biogeographical explanations, taxonomic schemes that admitted of heterogeneity, and affective research styles. Sociocultural anthropology, which took specialized shape at the beginning of the twentieth century, shared many properties with other field sciences, but its method--participant observation-was distinctive. Critical to the method's definition were the efforts of the British experimental psychologist-anthropologist W. H. R. Rivers, who relied on notions then widespread in Europe and the United States. The discipline's future mythic hero, Bronislaw Malinowski, embraced Rivers's model. For both men, proper fieldwork meant using the researcher's body as an instrument and entailed understanding both the anthropologist's body and the research subject's body as energy systems; this symmetry facilitated a relativist perspective. Participant observation remains central to sociocultural anthropology, but the discipline's pedagogic habits contributed to loss of memory of its energetic conceptualization. PMID:21667774

Socio-cultural valuation of ecosystem services in a transhumance social-ecological network  

DEFF Research Database (Denmark)

The ecosystem services framework is receiving increasing attention in the fields of policy and research. The assessment of human attitudes and perceptions regarding ecosystem services has been proposed as a promising tool for addressing complex problems associated with environmental change, particularly in the context of cultural landscapes. Transhumance is not only a farming practice responsible for shaping cultural landscapes but also an adaptive strategy based on mobility that may represent a useful approach to overcoming the growing challenges posed by accelerated environmental change. A socio-cultural valuation of ecosystem services associated with the Conquense Drove Road, one of the major transhumant networks still in use in Mediterranean Spain, was conducted via the distribution of questionnaires to 416 local residents and visitors to capture their perceptions regarding the importance of 34 ecosystem services (10 provisioning, 12 regulating, and 12 cultural) for both social and personal well-being. Overall, the ecosystem services considered to be the most important for social well-being were fire prevention, air purification and livestock. Most of the ecosystem services in question were perceived as declining, with the exception of those associated with recreation, scientific knowledge and environmental education. This study revealed that perceptions regarding the value of ecosystem services differed among respondents, depending on their age, place of origin and gender. Several methodological issues, as well as the implications of socio-cultural valuation for policy making, are also discussed here. © 2013 Springer-Verlag Berlin Heidelberg.

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

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english Khat (Catha edulis) is a plant of uncertain and highly controversial status grown in the countries around the Red Sea and on the eastern coast of Africa. The chewing of khat leaves has a deep-rooted religious and socio-cultural tradition. Khat is considered a cash crop and its cultivation is a sourc [...] e of economic value to the societies and nations involved. There have, however, been reports of negative economic effects on the individuals engaging in the habit of khat chewing. The increasing use of khat worldwide, along with the negative international attention that this has garnered, has led to the present status of uncertainty of the once indigenous practice of khat chewing. Scientists, mostly western Europeans, have tended to focus on problems related to khat with little attention to the positive role of khat chewing in society and the world at large. In addition, no report has directly associated khat with any organised crime, violence or antisocial activity, particularly in countries where khat is legalised. This paper reviewed the various areas of uncertainty and controversy relating to khat. Based on the findings of the review, further qualitative and quantitative research is required and a positive international approach to khat use at economic, religious and socio-cultural levels is advocated.

Sociocultural mediators of remembering : An extension of Bartlett's method of repeated reproduction  

DEFF Research Database (Denmark)

The reported research uses an extension of Bartlett's method of repeated reproduction to provide data on the sociocultural processes underlying reconstructive remembering. Twenty participants worked in pairs to remember the War of the Ghosts story 15 min and 1 week after presentation. The observed transformations were comparable to previous research with individuals. Going beyond previous research, we analyse participants' discourse to provide a window on the processes underlying these transformations. Textual excerpts demonstrate how imagery, narrative coherence, deduction, repetition, gesture, questioning and deferring contribute to the transformation and conventionalization of the material. These diverse sociocultural mediators are integrated into a partially coherent recollection by participants self-reflecting, or as Bartlett termed it, turning around upon their schemas. We demonstrate that this self-reflection is both a social and a psychological process, occurring because participants are responding totheir own utterances in the same way that they respond to the utterances of other people. These empirical findings are used to make a case for using discursive data to look not only at discursive processes but also at socially situated and scaffolded psychological processes.

The Role of Negative Evidence in the Acquisition of Sociocultural Aspects of First Language  

Directory of Open Access Journals (Sweden)

Full Text Available Children learn their native language in a relatively rapid time and are able to communicate from very early using language. But is the acquisition of their native culture and native language dependent on each other (LeVine & Norman, 2001; Riesman, 1993? The present study aims to investigate the extent to which parents provide their children with direct and indirect negative feedback while they are acquiring sociocultural aspects of their language. A group of parents (N=75 from three social backgrounds were interviewed. The results showed that parents used direct negative feedback more than indirect negative evidence while correcting a culturally inappropriate utterance (calling parents by their first names. Also it was found that parents from middle class socioeconomic status used more direct negative evidence than parents from a working class background who showed no significant difference regarding the use of different types of negative feedback. These results show the importance of negative feedback in the acquisition of sociocultural and pragmatic aspects of the native language.

Sociocultural factors in public acceptance: comparative risk studies involving France, the USA and the UK  

International Nuclear Information System (INIS)

Examples are given of two types of comparative study that explore the sociocultural factors that shape public attitudes. In the first, public perceptions of nuclear power were assessed by answers to a questionnaire on a broad range of factors by 1500 people in France and the USA. A degree of homogeniety was observed in the responses from France and the USA. Strikingly, both populations agreed in their evaluation of the health risk represented by nuclear power plant. Thus the apparently greater acceptance of nuclear power in France does not seem to be associated with a lesser perception of risk. However, presented with the statement ''We can trust the experts and engineers who build, operate and regulate nuclear power'' 66% of the French agreed compared to only 43% of the Americans. These results reflect two different types of relationship between society and authority. In the second study the approach to gaining public trust and acceptance in the siting of nuclear waste research facilities was compared between the UK and France. Striking differences were found. In this case, too, an explanation can be put forward in terms of the sociocultural variables which influence institutional decision making, particularly in the role and form given to authority. (UK)

Complexity and Sociocultural Urbanization of Spare Time in Magdalena Mixhuca Sports City  

Directory of Open Access Journals (Sweden)

Full Text Available This article derives from my thesis research project “Fragmentation and sociocultural urbanization of spare time. High-significance places in Magdalena Mixhuca Sports City”. Its purpose is to concisely present those considerations that allowed integrating transdisciplinary epistemological and methodological frameworks. An analytical method was designed to integrate epistemological considerations for cultural and deep hermeneutics analysis, and the principles of complex thinking and complex systems theory, with the purpose of explaining the spare time sociocultural urbanization that is taking place in this fragmented public space that is characteristic of Mexico City. We present here some of the results of the implementation of this analytical method based on hologramatic, recursive and dialogic principles, that allowed interpreting Magdalena Mixhuca Sports City (at first sight considered fragmented, disarticulated and chaotic as a fractal space, integrated by symbolic forms, socially and historically structured in this public space, from its origin, in 1958, up to the 21st century. We can conclude that these symbolic forms, located within a complex system, are condensed in high significance places such as Juan Escutia Sports Palace, Rodríguez Brothers Racetrack, Foro Sol, Gates 3 and 2, and Agustín Melgar Olympic Velodrome Esplanade, all of which have their own cultural dynamics that determine the characteristics, as a whole, of this sport centre.

Directory of Open Access Journals (Sweden)

Full Text Available Background & objectives: Malaria is a new emerging problem of Indian Thar Desert. The study wasattempted to find out some sociocultural factors associated with malaria transmission in this regionand to supplement social solutions to ongoing malaria control efforts in the desert part of Rajasthan.Methods: Interview technique was used for data collection on pre-tested schedules. In all 30 households(15 from low socioeconomic group and the same number of households from the high socioeconomicgroup in a village were selected following systematic random sampling technique. A total of 450respondents were selected randomly in 15 villages of Jaisalmer district, Rajasthan.Results: One-third of the respondents had neither taken treatment for malaria nor took part in the vectorcontrol operations because they did not consider mosquito bites to be harmful and took malaria as amild disease. Outdoor sleeping habits, sharing bed with children, uneasy and suffocation feeling inusing mosquito bednets or any other protective device also contributed to the spread of malaria in thestudy villages.Interpretation & conclusion: Community should be educated as a whole particularly the low socioeconomicgroup of people to bring changes in their beliefs, sociocultural and health practices to protectthemselves from mosquito bites by using bednets, repellents and other devices, such as wire meshscreening of house doors and windows.

{open_quotes}Virtual climate{close_quotes} and climate change assessment: Paving the way for workable climate change policies  

Energy Technology Data Exchange (ETDEWEB)

A climate change assessment framework that integrates physical change with societal vulnerability is proposed. The purpose of the assessment would be to focus research on the physical science uncertainties with the most potential to adversely affect key economic, political, and cultural activities. The framework centers on the concept of virtual climate, which is defined as the large-scale, protracted, and routinized augmentation/offset of natural climatic conditions. The assessment process would focus on the superimposition of climate change on those socio-cultural factors that determine the degree to which specific societal groups (regions) have already offset climate conditions to support preferred patterns of life.

An Investigation of Communication in Virtual High Schools  

Directory of Open Access Journals (Sweden)

Full Text Available Virtual schooling is an increasing trend for secondary education. Research of the communication practices in virtual schools has provided a myriad of suggestions for virtual school policies. The purpose of this qualitative study was to investigate the activities and processes involved in the daily rituals of virtual school teachers and learners with the goal of determining how regular phone calls by teachers contributed to the work habits of students. Eight virtual teachers were observed attempting to contact more than 60 struggling learners. Phone conversations with 12 of these learners showed that teachers repeatedly attempted to help them. Eleven students were interviewed and indicated preferences for written communications. Ten additional teachers who were interviewed emphasized the difficulty they had in reaching students by phone and the lack of student responses to phone-call attempts. The teachers in the study provided additional data regarding their regular communication patterns. Archival records from more than 100 contact attempts showed that approximately 20% of the students responded to teacher phone calls and less than half of these students completed the work requested. The interview data revealed that teachers believe written communications or multiple forms of communication may be more effective than regular phone calls. Future research should extend current research by expanding on sample size and investigating alternate methods of communication. Further investigation of learner responses to phone calls and of nonresponsive students could add to this data.

Cosmic Contact Censorship  

CERN Document Server

Till date we have not made Contact with any Extraterrestrial civilizations. The Fermi Paradox remains a paradox - the Great Silence prevails. In the light of the Rare Earth hypothesis, it seems that advanced life is exceedingly rare in the universe. Also, if there does exist some Extraterrestrial civilizations then still achieving Contact is extremely difficult as the very nature of the universe discourages Contact. It's as if there is a Cosmic Contact Censorship in place.

Contact solution algorithms  

Science.gov (United States)

Two algorithms for obtaining static contact solutions are described in this presentation. Although they were derived for contact problems involving specific structures (a tire and a solid rubber cylinder), they are sufficiently general to be applied to other shell-of-revolution and solid-body contact problems. The shell-of-revolution contact algorithm is a method of obtaining a point load influence coefficient matrix for the portion of shell surface that is expected to carry a contact load. If the shell is sufficiently linear with respect to contact loading, a single influence coefficient matrix can be used to obtain a good approximation of the contact pressure distribution. Otherwise, the matrix will be updated to reflect nonlinear load-deflection behavior. The solid-body contact algorithm utilizes a Lagrange multiplier to include the contact constraint in a potential energy functional. The solution is found by applying the principle of minimum potential energy. The Lagrange multiplier is identified as the contact load resultant for a specific deflection. At present, only frictionless contact solutions have been obtained with these algorithms. A sliding tread element has been developed to calculate friction shear force in the contact region of the rolling shell-of-revolution tire model.

Diagnostic accuracy in virtual dermatopathology  

DEFF Research Database (Denmark)

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

Applied virtual reality  

International Nuclear Information System (INIS)

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

Theft of Virtual Property — Towards Security Requirements for Virtual Worlds  

Science.gov (United States)

The article is focused to introduce the topic of information technology security for Virtual Worlds to a security experts’ audience. Virtual Worlds are Web 2.0 applications where the users cruise through the world with their individually shaped avatars to find either amusement, challenges or the next best business deal. People do invest a lot of time but beyond they invest in buying virtual assets like fantasy witcheries, wepaons, armour, houses, clothes,...etc with the power of real world money. Although it is called “virtual” (which is often put on the same level as “not existent”) there is a real value behind it. In November 2007 dutch police arrested a seventeen years old teenager who was suspicted to have stolen virtual items in a Virtual World called Habbo Hotel [Reuters07]. In order to successfully provide security mechanisms into Virtual Worlds it is necessarry to fully understand the domain for which the security mechansims are defined. As Virtual Worlds must be clasified into the domain of Social Software the article starts with an overview of how to understand Web 2.0 and gives a short introduction to Virtual Worlds. The article then provides a consideration of assets of Virtual Worlds participants, describes how these assets can be threatened and gives an overview of appopriate security requirements and completes with an outlook of possible countermeasures.

High efficiency virtual impactor  

Energy Technology Data Exchange (ETDEWEB)

Environmental monitoring of atmospheric air is facilitated by a single stage virtual impactor (11) for separating an inlet flow (Q.sub.O) having particulate contaminants into a coarse particle flow (Q.sub.1) and a fine particle flow (Q.sub.2) to enable collection of such particles on different filters (19a, 19b) for separate analysis. An inlet particle acceleration nozzle (28) and coarse particle collection probe member (37) having a virtual impaction opening (41) are aligned along a single axis (13) and spaced apart to define a flow separation region (14) at which the fine particle flow (Q.sub.2) is drawn radially outward into a chamber (21) while the coarse particle flow (Q.sub.1) enters the virtual impaction opening (41). Symmetrical outlet means (47) for the chamber (21) provide flow symmetry at the separation region (14) to assure precise separation of particles about a cutpoint size and to minimize losses by wall impaction and gravitational settling. Impulse defocusing means (42) in the probe member (37) provides uniform coarse particle deposition on the filter (19a) to aid analysis. Particle losses of less than 1% for particles in the 0 to 20 micron range may be realized.

Medical Virtual Public Services  

Directory of Open Access Journals (Sweden)

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

Understanding the limits of Marxist approaches to sociocultural studies of science education  

Science.gov (United States)

In the first three sections of this paper we comment on some of the ideas developed in the forum papers, pointing out possible misunderstandings and constructing new explanations that clarify arguments we made in the original article. In the last section we expand the discussion raised in the original paper, elaborating on the limits of the use of Marxist approaches to sociocultural studies of science education. Following insights suggested by Loxley et al. (Cult Stud Sci Edu. doi: 10.1007/s11422-013-9554-z, 2013) and detailed by Zuss (Cult Stud Sci Edu, 2014) on the commodification of knowledge, we sketch an analysis of how knowledge is transformed into capital to understand why contemporary scholars are likely to be engaged in a relation of production that resembles capitalist exploitation.

Preparing for rectal microbicides: sociocultural factors affecting product uptake among potential South american users.  

Science.gov (United States)

Objectives. We examined views on rectal microbicides (RMs), a potential HIV prevention option, among men who have sex with men and transgender women in 3 South American cities. Methods. During September 2009 to September 2010, we conducted 10 focus groups and 36 in-depth interviews (n?=?140) in Lima and Iquitos, Peru, and Guayaquil, Ecuador, to examine 5 RM domains: knowledge, thoughts and opinions about RM as an HIV prevention tool, use, condoms, and social concerns. We coded emergent themes in recorded and transcribed data sets and extracted representative quotes. We collected sociodemographic information with a self-administered questionnaire. Results. RM issues identified included limited knowledge; concerns regarding plausibility, side effects, and efficacy; impact on condom use; target users (insertive vs receptive partners); and access concerns. Conclusions. Understanding the sociocultural issues affecting RMs is critical to their uptake and should be addressed prior to product launch. PMID:24825222

Exploring Mexican-origin intimate partner abuse survivors' help-seeking within their sociocultural contexts.  

Science.gov (United States)

Women's responses to partner abuse are shaped by their particular sociocultural contexts. In this study, quantitative data were collected from 75 Mexican-origin women who survived intimate partner abuse, to identify variables associated with help-seeking to survive relationship abuse. Help-seeking was defined as use of formal (e.g., shelter) and informal (e.g., family) sources. Variables included two cultural variables: machismo (i.e., adherence to traditional gender roles) and familismo (i.e., valuing family cohesion and reciprocity), and four sociostructural variables: income, education, English proficiency, and immigrant status. Results indicated participants with higher levels of familismo sought informal help more frequently than those with lower levels. Women with grade school education, no English proficiency, and undocumented status sought formal help less frequently than those not constrained by these barriers. PMID:20055217

The wetlands of Magdalena medio Antioqueno from a physical and socio-cultural perspective  

International Nuclear Information System (INIS)

Wetlands are ecosystems with environmental and ecological importance that require of a new methodological and legal focus that allows developing conservation policies in agreement with the natural and socio-cultural conditions. In the Magdalena Medio Antioqueno, CORANTIOQUIA region, were recognized 362 wetlands, divided in two main groups; in Puerto Nare and Puerto Berrio to the south prevails herbaceous wetlands without permanent surface water, locally known as Bajos. In Yondo the wetlands have permanent surface water. The environmental dynamic depends from the geomorphologic and hydrological conditions and are affected in a differential way by the human action. The region is the result of a long occupation process that begins in prehistoric times and had changed depending on the different historical moments. This complex social configuration has given origin to diverse perceptions and types of appropriation of the wetlands what explains the identified environmental circumstances

Socio-cultural processes behind the differential distribution of organic farming in Denmark - a case study  

DEFF Research Database (Denmark)

Conversion to organic farming, along with driving forces and barriers, has been explored intensively during the past decade, while studies on localization and impacts of local socio-cultural processes on conversion to and diffusion of organic farming have been scarce. Concentrations of organic farms in Denmark differ according to county, and moreover there appeared to be large within-county variation in the density of organic farms. The present study explores the local aspects of conversion to organic farming and the factors that may help explain the variations in density and concentration of organic farms within smaller areas. The study is based on nine qualitative interviews with organic farmers from two neighboring areas, referred to as "mainland" and "island". Three farms were situated in the high-density area (mainland) and the remaining six in the low-density area (island). Furthermore, five advisors with connections to the area provided information on their local experiences and perceptions

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

Science.gov (United States)

The paper looks at the reason for the low incidence of retained abdominal packs following an abdominal operation in a third world country like Nigeria. It is generally agreed that this unfortunate situation is underreported. The reason for under-reporting is now given a socio-cultural perspective. Fear of litigation as would hold in the western world does not seem to be paramount here. Other explanations like fear of being made a scapegoat for something which may be due to spiritual attacks may be paramount. The paper concludes by recommending that the removal of impediments to disclosure of this adverse surgical event will lie in education, discouragement of scapegoatism and improvement in hospital services in the third world.

The sociocultural appraisals, values, and emotions (SAVE) framework of prosociality: core processes from gene to meme.  

Science.gov (United States)

The study of prosocial behavior--altruism, cooperation, trust, and the related moral emotions--has matured enough to produce general scholarly consensus that prosociality is widespread, intuitive, and rooted deeply within our biological makeup. Several evolutionary frameworks model the conditions under which prosocial behavior is evolutionarily viable, yet no unifying treatment exists of the psychological decision-making processes that result in prosociality. Here, we provide such a perspective in the form of the sociocultural appraisals, values, and emotions (SAVE) framework of prosociality. We review evidence for the components of our framework at four levels of analysis: intrapsychic, dyadic, group, and cultural. Within these levels, we consider how phenomena such as altruistic punishment, prosocial contagion, self-other similarity, and numerous others give rise to prosocial behavior. We then extend our reasoning to chart the biological underpinnings of prosociality and apply our framework to understand the role of social class in prosociality. PMID:24405363

Sociocultural determinants associated to pneumonia in Puno, Peru: a qualitative study  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To identify the sociocultural determinants of pneumonia through the perception of health workers and community in Puno, Peru. Methods: From June 8 to 11, 2009, we applied qualitative techniques including focus groups in administrative workers of the Regional Health Directorate of Puno, healthcare workers from a public hospital of the province of Juliaca, Puno, and schoolchildren between 8 and 9 years from a public school in the province of Juliaca. Projective techniques were also applied to the schoolchildren, who through free drawing expressed their feelings, opinions, reasons for behaviors and attitudes of both children and their parents, related to pneumonia. Focus groups were recorded and later transcribed; we also interviewed two relatives of a girl who died from pneumonia in the community of Uros, Puno, using a questionaire guide.Results: The determinants associated with pneumonia that were identified are lack of leadership and coordination of health workers in the care of patients with pneumonia, delayed in care and payments for health services, the influence of the mother-in-law who decides what to do with children with pneumonia, parents who medicate their children, children that stay alone at home uintil late at night and a delay in the attendance to the hospital; health workers recognized that attention in health services is limited and not of quality. Conclusions: The sociocultural determinants are lack of leadership and coordination of health teams, delays in care and payments for services, the mother-in law influence in decision making, self-medication and going to the hospital when the child is seriously ill.

Socio-cultural impacts of construction and regulation of the waterway of Oulujoki river  

International Nuclear Information System (INIS)

The purpose of study was to clarify the socio-cultural impacts of the regulation and construction of Oulujoki river on the everyday life of people. Changes in work and livelihood, living and living satisfaction, and leisure time and recreation are considered as variables. Quantitative and qualitative methods were combined in the study. The principal study material is composed of answers to a questionnaire and of 109 thematic interviews on the topic. The hold of the study is phenomenological-hermeneutical, with the intention to interpret the matter from the viewpoint of the attitudes and requirements of the waterway users. The theoretical frame of reference was culture-ecological point of view and adaptive process. The emphasis of the study is on sociocultural adaptation. The attitude towards waterway construction and regulation was dependent on the background of the person interviewed. The attitude was considered e.g. by various interest groups and professional groups, such as farmers, inhabitants on the shore, recreation users, fishermen, municipal elected officials. Other important variables were age, family stage and sex. Big local differences in the attitudes could also be found. While prevailing values in society and peoples' modes of living are changing, also the attitude towards waterway and changes caused by waterway construction has changed in the region studied. The impacts on the sources of livelihood are minor for the moment, the impacts on living satisfaction and recreations are significant. While leisure time is increasing the recreation value of waterway increases, too. At the construction stage of the river, the economical and productional advantages took priority, and then no attention was paid to recreational use

Sociocultural Tailoring of a Healthy Lifestyle Intervention to Reduce Cardiovascular Disease and Type 2 Diabetes Risk Among Latinos  

Science.gov (United States)

Background Suboptimal lifestyle factors in combination with genetic susceptibility contribute to cardiovascular disease and type 2 diabetes risk among Latinos. We describe a community–academic collaboration that developed and explored the feasibility of implementing a socioculturally tailored, healthy lifestyle intervention integrating genomics and family history education to reduce risk of cardiovascular disease and type 2 diabetes among Latinos. Community Context The community-based participatory research was conducted with communities in Kentucky, which has a rapidly growing Latino population. This growth underscores the need for socioculturally appropriate health resources. Methods Su Corazon, Su Vida (Your Heart, Your Life) is a Spanish-language, healthy lifestyle educational program to reduce cardiovascular disease and type 2 diabetes risk among Latinos. Twenty natural leaders from an urban Latino community in Kentucky participated in sociocultural tailoring of the program and development of a genomics and family history module. The tailored program was presented to 22 participants to explore implementation feasibility and assess appropriateness for community use. Preintervention and postintervention assessments of genomic knowledge and lifestyle behaviors and qualitative postintervention evaluations were conducted. Outcomes Postintervention improvements in health-promoting lifestyle choices and genomic knowledge specific to cardiovascular disease and type 2 diabetes suggested that the program may be effective in reducing risk. Feedback indicated the program was socioculturally acceptable and responsive to community needs. Interpretation These findings indicated that a tailored healthy lifestyle program integrating genomics and family history education was socioculturally appropriate and may feasibly be implemented to reduce cardiovascular disease and type 2 diabetes risk in a Latino community with limited health care resources. The project highlights contributions of community-based processes in tailoring interventions that are appropriate for community contexts.

Naqueles primeiros tempos, esses relacionamentos virtuais foram duramente criticados. Nos dias atuais, vemos que os relacionamentos mediados pelas novas redes de telecomunicação (Internet e telefonia celular) continuam gerando reações negativas radicais. O objetivo do presente artigo é mostrar o quanto essas reações são infundadas e, deste modo, combater sua difusão. Para tanto, toma o recente trabalho de um renomado sociólogo - Zygmunt Bauman - como exemplar desse tipo de visão e a ele contrapõe inúmeros resultados de pesquisa internacionais e nacionais. Tal procedimento permite apresentar uma visão alternativa de diferentes tipos de interação e relacionamento virtuais gerados por diferentes tecnologias. Abstract in english Since the early days of Internet diffusion, in the mid 1990's, virtual sociability has been raising a great discussion. In contrast to the contacts between acquaintances made possible by landline telephony, Internet collective interaction environments generated the possibility of meeting people and [...] making friends exclusively online. In those early days, these virtual relationships were strongly criticized. Nowadays, we realize that the relationships mediated by the new telecommunication networks (Internet and cellular telephony) still provoke radical negative reactions. The present paper aims at restraining or at least decelerating the diffusion of such reactions. For this purpose, it takes the recent work of a renowned sociologist - Zygmunt Bauman - as an example of this kind of view and confronts it with various results from national and international research. Such procedure allows for the presentation of an alternative view of different types of virtual interaction and virtual relationships made possible by different technologies.

The ethnography of virtual reality  

Directory of Open Access Journals (Sweden)

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

Navigation Assistance in Virtual Worlds  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper we report about ongoing research on navigation assistance in virtual environments. Our aim is to contribute to the development of forms of navigation assistance that enable non-professional visitors of a virtual environment to find their way without previous training. The environment used in this re-search is a virtual theatre that models a real world music theatre. This virtual theatre can be used for exploration as well as for transactions and goal-directed search for information. We first present some de-sign principles for navigation assistance in virtual environments and some design criteria for assistance by personal agents. Subsequently we describe how these principles and criteria have been implemented in our experimental virtual theatre environment. Finally we give an overview of future research plans.

Verbal Interactions in Virtual Worlds  

CERN Multimedia

We first discuss respective advantages of language interaction in virtual worlds and of using 3D images in dialogue systems. Then, we describe an example of a verbal interaction system in virtual reality: Ulysse. Ulysse is a conversational agent that helps a user navigate in virtual worlds. It has been designed to be embedded in the representation of a participant of a virtual conference and it responds positively to motion orders. Ulysse navigates the user's viewpoint on his/her behalf in the virtual world. On tests we carried out, we discovered that users, novices as well as experienced ones have difficulties moving in a 3D environment. Agents such as Ulysse enable a user to carry out navigation motions that would have been impossible with classical interaction devices. From the whole Ulysse system, we have stripped off a skeleton architecture that we have ported to VRML, Java, and Prolog. We hope this skeleton helps the design of language applications in virtual worlds.

Contact freezing: a review  

Directory of Open Access Journals (Sweden)

Full Text Available This manuscript compiles both theoretical and experimental information on contact freezing with the aim to better understand this potentially important but still not well quantified heterogeneous freezing mode. There is no complete theory that describes contact freezing and how the energy barrier has to be overcome to nucleate an ice crystal by contact freezing. Experiments on contact freezing indicate that it can initiate ice formation at the highest temperatures. A difference in the freezing temperatures between contact and immersion freezing has been found using different instrumentation and different ice nuclei. There is a lack of data on collision rates in most of the reported data, which inhibits a quantitative calculation of the freezing efficiencies. Thus, new or modified instrumentation to study this heterogeneous freezing mode in the laboratory and in the field are needed. Important questions concerning contact freezing and its potential role for ice cloud formation and climate are also summarized.

Interactive Virtual Cinematography  

DEFF Research Database (Denmark)

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

The virtual case report.  

Science.gov (United States)

Reports of clinical happenings are coming under increasing suspicion because of their piecemeal nature and their problematic reliance on memory. Recent research on eyewitness testimony has raised the further concern that memory of an event can be easily and unwittingly influenced by something heard or seen after the fact. Once the psychoanalyst's memory has come under the influence of whatever theory is dominant, we can expect both an overselection of clinical happenings consistent with that theory, and an unwitting alteration of those that do not agree. Seemingly true case reports may be more virtual than veridical. PMID:12391936

Adapting Virtual Camera Behaviour  

DEFF Research Database (Denmark)

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

Virtual corporations, enterprise and organisation  

Directory of Open Access Journals (Sweden)

Full Text Available Virtual organisation is a strategic paradigm that is centred on the use of information and ICT to create value. Virtual organisation is presented as a metamanagement strategy that has application in all value oriented organisations. Within the concept of Virtual organisation, the business model is an ICT based construct that bridges and integrates enterprise strategic and operational concerns. Firms try to ameliorate the impacts of risk and product complexity by forming alliances and partnerships with others to spread the risk of new products and new ventures and to increase organisational competence. The result is a networked virtual organization.

When Virtual Worlds Expand  

Science.gov (United States)

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

Virtual Optical Comparator  

Energy Technology Data Exchange (ETDEWEB)

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

Colon Cancer: Virtual Detection  

Science.gov (United States)

Colon cancer is both the second most pervasive cancer to attack humans and one of the most preventable. One of the sad reasons for its prevalence has little to do with genes, diet, or overall health. Instead, it is the social stigma of the colon and rectum and the associated test --the colonoscopy -- which drives this cancer to the top of the list of killers. As with many cancer types, colon and rectal cancer is best treated in the early stages. And, when done so, the success of treatment is exponentially greater than dealing with it later on. While the typical test, the colonoscopy, is reliable, safe, and relatively easy, it still requires temporary sedation of the patient and the insertion of a camera through the large intestines. While the patient is sleepy and relaxed due to the sedation, and the procedure is reliably painless, the very thought of the proceture has kept many away. Now, with the advent of amazing virtual imaging technology, a virtual colonoscopy can be performed in seconds without sedation, and without the insertion of a camera. While there are pros and cons to each -- namely that by using the old method, any growths can be removed by the colonoscope immediately -- this may be the answer for crossing the formally highest hurdle: simply getting people in the door for testing. The several sites below offer a look at this new technology. Teachers will hopefully value not only the descriptive sites, but also the link to a related lesson plan.The first link leads to a segment from PBS' Newshour and offers a very good introduction to the topic. The link leads to your choice of the transcript, audio, or video of the interview conducted by Margaret Warner with Dr. Perry Pickhardt, radiologist at the University of Wisconsin -- Madison and co-director of a recent virtual colonoscopy study found in the New England Journal of Medicine and the object of a lot of buzz in the medical world. The second site leads to the University of Wisconsin's press release on the study's findings and the technology itself. The third site, while a bit technical for many readers, takes you to the New England Journal of Medicine website and the actual report produced by Dr. Pickhardt and his colleagues on their findings related to virtual colonoscopy. The fourth link leads the foremost cancer information center sponsored by the U.S. government, the National Cancer Institute and its web home for Colon and Rectal cancer. This is a great site to obtain both general and specific information related to the disease and the various treatments. The next link leads an exceptionally well produced series of reports by a Madison (Wisconsin) area television station, WISC. Its web home, channel3000.com, offers this site which gives a good report of virtual colonoscopy as well as many links to additional information. Finally, teachers, the last link leads back to PBS.org and a great lesson that asks students (grades 6-8) to think about this topic from its scientific point of view.

Method for resonances and virtual states: Efimov virtual states  

International Nuclear Information System (INIS)

A simple method is proposed for the calculation of the position and residue of low-energy resonances and virtual states located in the unphysical sheet associated with the lowest two body scattering threshold. Instead of analytically continuing the scattering equation for the t matrix into the unphysical sheet we propose an approximate solution of the scattering equation with known analytic properties and continue it analytically into the unphysical sheet. The poles of the analytically continued solution in the unphysical sheet correspond to virtual states and resonances. The present method is applied to study the 1S0 virtual state of the two nucleon system, the Efimov virtual states in the three-boson Amado model and the spin doublet virtual state of the three-nucleon system

Los esquemas de certificacion de playas turisticas en America Latina: Evaluación del componente socio-cultural y el nivel participativo  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish Las playas turísticas son recursos costeros de alta importancia ambiental y económica. Los esquemas de certificación de playas turísticas (ECP) han sido creados para proteger estos recursos, a su vez promoviendo alto nivel de calidad turística. No obstante, las playas en América Latina muchas veces [...] son la fuente principal de ingresos de las comunidades costeras, que por el derecho de uso del bien público deben ser considerados en la gestión. Este trabajo tiene el objetivo de evaluar el componente socio-cultural y el nivel de participación en los ECP Latinoamericanos en dos niveles de análisis. Primero, a través de los objetivos socio-culturales y de participación del Manejo Integrado Costero (MIC), se definieron los niveles de participación e inclusión de los aspectos sociales de los nueve ECP en América Latina. Segundo, bajo el enfoque de las políticas públicas se analizaron los tipos de participación presentes en cada ECP. En resultado, los ECP Latinoamericanos se caracterizan por un fuerte enfoque arriba-abajo (top-down). Los ECP son poco participativos, abarcando principalmente las cuestiones ambientales y de calidad turística. Las debilidades en el tema de aspectos socio-culturales y de participación son evidentes, lo que pone en cuestión la efectividad de los ECP como una herramienta para la gestión sostenible. Abstract in english Evaluation of the Socio-Cultural Component and Participation Level in Latin American Tourist Beach Certification Schemes. The tourism beaches are coastal resources of great environmental and economic importance. The beach tourism certification schemes have been created to protect those resources, at [...] the same time promoting high level of tourism quality. However, the Latin American beaches are often the principal source of income for coastal communities that for the right to use the public mean should be considered in the management. This work has an objective to evaluate the socio-cultural component and level of community participation in Latin American beach certifications through two level analyses. First, through socio-cultural and participative objectives of Integrated Coastal Management, the levels of participation and inclusion of socio-cultural aspects were defined in the nine beach certifications. Second, under the approach of public policies, the types of participation in each certification scheme were analyzed. In conclusion, the Latin American beach certification schemes are characterized by strong top-down approach. The certifications are little participative, focusing mainly on environmental and tourism quality issues. The weaknesses in the subject of socio-cultural aspects and community participation are evident, which puts in question the effectiveness of beach certifications as a tool for sustainable management.

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

Superconducting Quantum Point Contacts  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We review our experiments on the electronic transport properties of atomic contacts between metallic electrodes, in particular superconducting ones. Despite ignorance of the exact atomic configuration, these ultimate quantum point contacts can be manipulated and well characterized in-situ. They allow performing fundamental tests of the scattering theory of quantum transport. In particular, we discuss the case of the Josephson effect.

Thermal contact correlations  

Science.gov (United States)

The theoretical relationships for determining contact, gap, and joint conductances are developed for conforming rough surfaces for first loading. The dimensionless conductances are functions of the relative contact pressure, surface parameters, conductivity ratio, and a fluid parameter which depends upon several gas and surface characteristics. The proposed conductance correlations are supported quantitatively by some previous experimental results.

Systemic contact dermatitis.  

Science.gov (United States)

Systemic contact dermatitis is an inflammatory skin disease that may occur in persons with contact allergy when they are exposed to the hapten orally, transcutaneously, per rectum, intravesically, intravenously, or by inhalation. The most common causes of systemic contact dermatitis are drugs used both topically and systemically. Other causes are ubiquitously occurring haptens, such as the metals nickel, cobalt, gold, and chromate, and aromatic substances such as spices. Avoidance of the offending hapten is the most obvious treatment. For some haptens, such as nickel, diet treatment may be effective. Chelation therapy with disulfiram is another therapeutic option in nickel-allergic patients with systemic contact dermatitis. Hyposensitization therapy has been attempted with some success in systemic contact dermatitis caused by nickel and Parthenium hysterophorus. PMID:22097987

Virtuality and Reality in Science  

International Nuclear Information System (INIS)

This book compiles eight contributions devoted to the topical question about the relation between virtuality and reality. In the theoretical frame of quantum and relativistic particle physics, the concept of virtuality is used according to its strict and precise meaning. In this context, particles are generally invented before their discovery. Some famous historical experiments which led to the postulation and then the discovery of new particles are mentioned. These examples are used to illustrate and to discuss the concept of virtuality as well as the physical reality of virtual processes. But, how can the concept of virtuality in other scientific fields be applied ? In order to answer this question, the concepts of virtuality and reality are discussed in other branches of physics as well as in other fields such as geophysics, cosmology and biology. Philosophical and sociological implications of virtual realities are also considered. Moreover, in relation to virtuality and reality, the connections between modeling, simulation and experimentation, their respective roles, the advantages and risks of their use are discussed (in relation to nuclear sciences and geophysical problems) (N.T.)

Notion of a virtual derivative  

CERN Document Server

Diagrams as a graphic expresion of derivatives is proposed for calculation of derivatives for composed function. The concret diagram is understood as a virtual derivative in contrast of concret derivative. In polynomial expression of functions derivative the concret derivative will be every monomic member, and the virtual derivative represent the sum of similar monomic members. The word virtual denotes that we dont need to know every virtual derivative, we don't write all the sequence of these virtual derivatives, and simply pick the needed one. This is in contrast of tradition to write the whole algebraic expresion as a denotion of whole function's derivative. Such graphic expresion can be helpful in the problems of differential geometry, in the various asymptotic expantions, also in the solution of some differential equations.

Thus, faculty moves to the background and the main role falls on the student body. This a [...] rticle is centered on a conciliatory experience (also novel in our faculty) of linking three related disciplines in the classroom: sociocultural animation, community development and education for development. All of this is framed in a participative methodology, developing the competency of teamwork and thus giving students a featuring role. This experience is developed in the course "Educational strategies for sociocultural animation adn community development" in the second term of the degree in the Social Education in the 2011/2012 academic course in the Universidad Pablo de Olavide, Sevilla, España.

Primitive Virtual Negative Charge  

CERN Document Server

Physical fields, such as gravity and electromagnetic field, are interpreted as results from rearrangement of vacuum particles to get the equilibrium of net charge density and net mass density in 4-dimensional complex space. Then, both fields should interact to each other in that physical interaction is considered as a field-to-field interaction. Hence, Mass-Charge interaction is introduced with primitive-virtual negative charge defined for the mass. With the concept of Mass-Charge interaction electric equilibrium of the earth is discussed, especially about the electric field and magnetic field of the earth. For unsettled phenomena related with the earth's gravity, such as antigravity phenomenon, gravity anomalies during the solar eclipses, the connection between geomagnetic storms and earthquakes, etc., possible explanations are discussed.

The Virtual Observatory Registry  

CERN Document Server

In the Virtual Observatory (VO), the Registry provides the mechanism with which users and applications discover and select resources -- typically, data and services -- that are relevant for a particular scientific problem. Even though the VO adopted technologies in particular from the bibliographic community where available, building the Registry system involved a major standardisation effort, involving about a dozen interdependent standard texts. This paper discusses the server-side aspects of the standards and their application, as regards the functional components (registries), the resource records in both format and content, the exchange of resource records between registries (harvesting), as well as the creation and management of the identifiers used in the system based on the notion of authorities. Registry record authors, registry operators or even advanced users thus receive a big picture serving as a guideline through the body of relevant standard texts. To complete this picture, we also mention comm...

Virtual Pig Dissection  

Science.gov (United States)

Dissection can be an aspect of scientific education that can make some parties queasy, but it is a fascinating way to learn more about the different body systems, their operations, and basic animal anatomy. Entering the world of pig dissection can make budding scientists even more squeamish, but they need never fear, as this site allows these individuals the opportunity to engage in a bit of virtual pig dissection. Originally created by Professor Earl W. Fleck of Whitman CollegeâÂÂs biology department, the site lets users go inside the pig to learn about its various systems, via a set of high-quality color photographs, which can be viewed at different angles and perspectives. Of course, what would a lab be without a quiz? Rounding out the site, visitors can take short quizzes on the pigâÂÂs anatomy and such.

Automated virtual colonoscopy  

Science.gov (United States)

Virtual colonscopy (VC) is a minimally invasive alternative to conventional fiberoptic endoscopy for colorectal cancer screening. The VC technique involves bowel cleansing, gas distension of the colon, spiral computed tomography (CT) scanning of a patient's abdomen and pelvis, and visual analysis of multiplanar 2D and 3D images created from the spiral CT data. Despite the ability of interactive computer graphics to assist a physician in visualizing 3D models of the colon, a correct diagnosis hinges upon a physician's ability to properly identify small and sometimes subtle polyps or masses within hundreds of multiplanar and 3D images. Human visual analysis is time-consuming, tedious, and often prone to error of interpretation.We have addressed the problem of visual analysis by creating a software system that automatically highlights potential lesions in the 2D and 3D images in order to expedite a physician's interpretation of the colon data.

The virtual temporal bone.  

Science.gov (United States)

The human temporal bone is a 3-dimensionally complex portion of the skull that contains delicate and vital anatomic structures imbedded within dense bone. Current teaching tools have proven to be only marginally adequate for the needs of the aspiring otologic surgeon in learning this anatomy. A variety of image processing and reconstruction techniques were used to reconstruct an anatomically accurate 3-dimensional model of the human temporal bone from serial histologic sections. Using CAVE technology, the model can be manipulated in a stereoscopic virtual environment so that it can be studied from any viewpoint, greatly simplifying the task of learning this anatomy. Applications in surgical planning and Internet based teaching are discussed. PMID:10180566

The virtual knife  

DEFF Research Database (Denmark)

Since post World War II and until 2008 the Danish pig producing industry (DPPI) has been in a continuing state of growth. In spite of an ever fiercer competition DPPI has managed to protect its position as export leader by maintaining a focus on research and development. Today, DPPI is in a state of recession and must increase the efficiency if not to reduce the production capacity further. The industry recognizes that a more efficient use of the raw materials is one of the largest and most important challenges. To meet this challenge it is a necessity to get a better understanding of the biological variation of pigs. The development of models for describing the biological variation of pigs is one of the key components needed to attain a better sorting of the pig carcasses and an improved cutting in the abattoirs. Such models can be related to possible products, which can be related to potential yield and order books. The Danish Meat Research Institute (DMRI) is currently constructing a representative database of virtual representations of pigs using X-ray Computed Tomography (CT). The database will serve as the foundation for the diversity modeling of pigs and for extracting predictors of quality and optimal use. This thesis integrates well-known techniques from the medical image analysis into the development of tools for automated analysis of the morphology of pigs. E.g. elastic image matching has been applied to establish spatial correspondence between the virtual representations of pigs in the database. The establishment of spatial correspondence is an essential preprocessing step for most automated analysis using the database.

Asynchronous Variational Contact Mechanics  

CERN Multimedia

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.

Video Conferencing for Opening Classroom Doors in Initial Teacher Education: Sociocultural Processes of Mimicking and Improvisation  

Directory of Open Access Journals (Sweden)

Full Text Available In this article, we present an alternative framework for conceptualising video-conferencing uses in initial teacher education and in Higher Education (HE more generally. This alternative framework takes into account the existing models in the field, but – based on a set of interviews conducted with teacher trainees and wider analysis of the related literature – we suggest that there is a need to add to existing models the notions of ‘mimicking’ (copying practice and improvisation (unplanned and spontaneous personal learning moments. These two notions are considered to be vital, as they remain valid throughout teachers’ careers and constitute key affordances of video-conferencing uses in HE. In particular, we argue that improvisational processes can be considered as key for developing professional practice and lifelong learning and that video-conferencing uses in initial teacher education can contribute to an understanding of training and learning processes. Current conceptualisations of video conferencing as suggested by Coyle (2004 and Marsh et al. (2009 remain valid, but also are limited in their scope with respect to focusing predominantly on pragmatic and instrumental teacher-training issues. Our article suggests that the theoretical conceptualisations of video conferencing should be expanded to include elements of mimicking and ultimately improvisation. This allows us to consider not just etic aspects of practice, but equally emic practices and related personal professional development. We locate these arguments more widely in a sociocultural-theory framework, as it enables us to describe interactions in dialectical rather than dichotomous terms (Lantolf & Poehner, 2008.

Socio-Cultural Aspects of Chagas Disease: A Systematic Review of Qualitative Research  

Science.gov (United States)

Background Globally, more than 10 million people are infected with Trypanosoma cruzi, which causes about 20 000 annual deaths. Although Chagas disease is endemic to certain regions of Latin America, migratory flows have enabled its expansion into areas where it was previously unknown. Economic, social and cultural factors play a significant role in its presence and perpetuation. This systematic review aims to provide a comprehensive overview of qualitative research on Chagas disease, both in endemic and non-endemic countries. Methodology/Principal Findings Searches were carried out in ten databases, and the bibliographies of retrieved studies were examined. Data from thirty-three identified studies were extracted, and findings were analyzed and synthesized along key themes. Themes identified for endemic countries included: socio-structural determinants of Chagas disease; health practices; biomedical conceptions of Chagas disease; patient's experience; and institutional strategies adopted. Concerning non-endemic countries, identified issues related to access to health services and health seeking. Conclusions The emergence and perpetuation of Chagas disease depends largely on socio-cultural aspects influencing health. As most interventions do not address the clinical, environmental, social and cultural aspects jointly, an explicitly multidimensional approach, incorporating the experiences of those affected is a potential tool for the development of long-term successful programs. Further research is needed to evaluate this approach.

Obeying God? Obeying Paul? Bridging the socio-cultural context in the interpretation of Biblical imperatives  

Directory of Open Access Journals (Sweden)

Full Text Available When do we encounter God in the Pauline imperatives, or when is it Paul, the man of his times, that we are dealing with? This article develops a model to help us determine the reach of the imperatives into our socio-cultural context today. The imperatives are shown to be more than ad hoc injunctions but, rather, legitimate expressions of the new symbolic world in which both Paul and believers participate by faith. The imperatives carry an illocutionary force which relies on such a shared symbolic world. By analysing Paul’s imperatives in terms of this symbolic world it is clear that he, at times, simply accepted the dominant cultural interpretation of reality of his day at the cost of limiting the expression of his symbolic world. At other times he modified the dominant cultural interpretation by calling believers to act contra-culturally in the light of the gospel’s new interpretation of reality. There are also instances where Paul directly rejects certain aspects of the culture of the day in the light of the symbolic world. Paul’s flexibility to develop a variety of responses towards the dominant culture of his day in the light of the indicatives of the gospel message provides an important key to developing a model to determine ‘if?’, ‘when?’ and ‘how?’, to apply the imperatives into our context today.

The economic, demographic, sociocultural and political setting for emigration from Sri Lanka.  

Science.gov (United States)

This study of emigration from Sri Lanka is introduced by a brief review of the situation during the colonial period and an overview of recent migration experience. The second section of the paper deals with data collection and sources for labor migration, political migration, and estimates of total net migration. The third section looks at economic and demographic trends in terms of the growth of the economy, population growth and social well-being, the growth of the labor force, unemployment, the structure of the work force, internal migration and access to agricultural lands, and income distribution and poverty. The sociocultural setting is then explored by considering exposure to the international environment, ethnicity and cultural affinity, the formation of information and job placement networks, the supportive role of the family, and the impact of success and failure. Moving on the influence of the political setting, the paper then discusses the government policy of foreign employment promotion as well as the influence of political developments on migration. In conclusion, the paper notes that future demand for domestic service workers will likely increase, and that Sri Lanka will continue to have a surplus of workers to fill this demand until the end of the 1990s, when a tightening domestic labor market and increased real wages will ease the push for migration. Political factors will continue to favor migration, however, unless a liberal democratic regime becomes the governing force in Sri Lanka. PMID:12347013

Analysing young children’s thinking about natural phenomena: A sociocultural/cultural historical perspective  

Directory of Open Access Journals (Sweden)

Full Text Available Vygotsky’s sociocultural/cultural historical theory emphasised the notion of semiotic mediation – or how thinking is transformed through signs (such as language and cultural tools (such as drawings from an intermental to an intramental plane. While the ideas of Vygotsky have become well-accepted within research in early childhood education in Australia, they are somewhat slower to be adopted within science education research. Yet they offer the potential for gaining new understandings of how young children’s thinking about the world develops. This article will demonstrate one way in which aspects of Vygotsky’s (1987-1999 work, particularly his ideas about semiotic mediation can inform analysis of children’s thinking about the world. Focusing on conversations with children about natural phenomena, and drawings they completed during those conversations, the analysis identifies a number of significant issues that are not normally revealed within the dominant forms of analysis which draw on constructivist perspectives. The findings, which reveal complex and dynamic aspects of children’s thinking, have implications for both teachers and researchers working with young children – especially within science education and science education research.

A socio-cultural approach to learning in the practice setting.  

Science.gov (United States)

Practice learning is an essential part of the curriculum and accounts for approximately 60% of the current pre-registration nursing programmes in the Republic of Ireland. The nature and quality of the clinical learning environment and the student nurses' experience of their practice placements is recognised as being influential in promoting the integration of theory and practice. However, the problem experienced by many learners is how to relate their theoretical knowledge to the situation-at-hand within the practice setting. Socio-cultural or activity theories of learning seek to explain the social nature of learning and propose that knowledge and learning are considered to be contextually situated. Lave and Wenger (1991) argue that learning is integrated with practice and through engagement with a community of practice, by means of sponsorship; students become increasingly competent in their identity as practitioners. This paper examines the changes which have occurred within the pre-registration nursing curriculum in the Republic of Ireland with the transition from the apprenticeship system to the graduate programme, and the resulting reduction in clinical learning hours. It also examines the potential impact on the development of student learning with the implementation of the concepts proposed by Lave and Wenger to learning in the practice setting. PMID:20362367

Methods We investigated socio-cultural determinants associated with hepatitis B screening in male and female, first and second generation Turkish migrants, by means of Focus Group Discussions. Results Socio-cultural themes related to hepatitis B screening were identified; these were social norm, social support, sensitivity regarding sexuality, reputation, responsiveness to authority, religious responsibility, cleanliness and religious doctrine regarding health and disease, and the perceived efficacy of Dutch health care services. Motivating factors were the (religious responsibility for one's health, the perceived obligation when being invited for screening, and social support to get tested for hepatitis B. Perceived barriers were the association of hepatitis B screening with STDs or sexual activity, the perception of low control over one's health, and the perceived low efficacy of the Dutch health care services. Reputation could act as either a motivator or barrier. Conclusion This study identified relevant socio-cultural themes related to hepatitis B screening, which may serve to customize interventions aimed at the promotion of voluntary hepatitis B screening in the Turkish-Dutch population in the Netherlands.

The Influence of Socio-cultural Variables on Consumers’ Perception of Halal Food Products: A Case of Masvingo Urban, Zimbabwe  

Directory of Open Access Journals (Sweden)

Full Text Available The main purpose of this paper is to examine the impact of socio-cultural variables on consumers’ perception onhalal food products (food prepared according to Islamic dietary laws. We assume that a number of socio-culturalfactors affect consumers’ purchase of food products especially education, religion, occupation and socialstratification. As the Halal principles are taken from the Syariah law (Law of Islam, how do consumers inMasvingo, Zimbabwe view the food products that are prepared under Islamic dietary laws? This study wasrekindled by the contention that Zimbabwe is largely a Christian country and may prefer to be guided byChristian values founded on Biblical laws. We had four hypotheses which were tested using Spearman’s rankcorrelation coefficient. The results revealed that indeed socio-cultural factors have little or no influence on anindividual consumer’s perception on consumption of halal certified food products. However, it was found outthat the Islamic consumers and other religious groups other than protestant, catholic, baptist and apostolic arehighly sensitive to their socio-cultural orientations.

A Wall out of Place: a Hydrological and Sociocultural Analysis of Physical Changes to the Lakeshore of Como, Italy  

Directory of Open Access Journals (Sweden)

Full Text Available The construction of a flood protection structure that obscured views of the lake in Como, northern Italy, led to unprecedented public protest in 2009–2010 and to the eventual dismantlement of the structure. This provided a focus to investigate the delicate interplay of technical and cultural matters in environmental policy—in this case, catchment management and flood prevention. This article shows how a focus on hydrological control in isolation from the rest of the catchment and from the sociocultural context contributed to the project's failure. A key message of the article is that data and analyses from the environmental and social sciences are both pivotal to environmental planning, as they inform different yet interdependent components of a single project. There is value in integrating technical and sociocultural knowledge, both at the academic level, as illustrated by the mixed methods used in this article, and at the policy level, through management frameworks that emphasize cross-sectoral learning and public participation. The analysis also reveals that the notion of "place" has a central role to play in this process of integration, both as a conceptual bridge between technical and sociocultural components of environmental studies and as an emphasis in environmental planning activities to foster the interest and engagement of communities.

Pediatric contact dermatitis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Allergic contact dermatitis (ACD) in children, until recently, was considered rare. ACD was considered as a disorder of the adult population and children were thought to be spared due to a lack of exposure to potential allergens and an immature immune system. Prevalence of ACD to even the most common allergens in children, like poison ivy and parthenium, is relatively rare as compared to adults. However, there is now growing evidence of contact sensitization of the pediatric population, and i...

[Contact dermatitis from hexamidine].  

Science.gov (United States)

Twenty patients with contact dermatitis to hexamidine, a commonly used antiseptic solution are reported. They have been collected during a 7 months period, thus suggesting that this contact allergy is not infrequent. Hydroalcoholic solution applied on epidermless skin is most frequently responsible for the contact dermatitis. Clinical features are very peculiar with papular semi-spheric and papulo-vesicular lesions being more frequently seen than classical vesicular eczema lesions. Due to this peculiar aspect, contact dermatitis to hexamidine is frequently misdiagnosed. The delay between onset and diagnosis has been sometimes longer than one year. It is four months as a mean. Pathologic aspect of these lesions is unusual too: dermal vasculitis either lymphocytic or with pycnotic polymorphonuclear is the most frequent aspect (14 out of 23 histological sections). Epidermal spongiosis is infrequent (5 cases). Contact dermatitis has usually a long standing evolution despite removal of the allergen and topical cortico-steroid treatment. Patch-test to hexamidine are frequently followed by a worsening of cutaneous lesions. One case of anaphylaxis following patch-testing has been reported. Clinical and pathological features of this contact dermatitis, suggests that humoral immune mechanisms play a key-role in its pathogenesis. PMID:6517448

A Framework for Virtual Hand Haptic Interaction  

Science.gov (United States)

Virtual hand interactions play key roles in virtual environments. The recent addition of force feedback to virtual reality simulations has enhanced their realism, especially when dexterous manipulation of virtual objects is concerned. However, though there exist many works on virtual hand modeling regarding computer animation and interaction applications, much less attention is paid on haptic modeling of virtual hand. In this paper, we propose a framework for virtual hand haptic interaction. The modeling of a sophisticated virtual hand for haptic interactions is investigated with special attention paid on issues of visual realism, motion realism as well as force sensation. Specifically, our virtual hand model simulates natural anatomy in its appearance, motion and deformation, and reflects the feature of force feedback datagloves. Besides, virtual hand interactions based on the constructed virtual hand model are discussed. The proposed framework has been tested on a PC with a force feedback dataglove.

Simple, extremely low resistance contact system to n-InP that does not exhibit metal-semiconductor intermixing during sintering  

Science.gov (United States)

Contact formation to InP is plagued by the violent metal-semiconductor intermixing that takes place during the contact sintering process. We have discovered a truly unique contact system, involving Au and Ge, which is easily fabricated, which exhibits extremely low values of contact resistivity, and in which there is virtually no metal-semiconductor interdiffusion, even after extended sintering. We present a description of this contact system and suggest possible mechanisms to explain the observed behavior.

Modeling Virtual Organization Architecture with the Virtual Organization Breeding Methodology  

CERN Document Server

While Enterprise Architecture Modeling (EAM) methodologies become more and more popular, an EAM methodology tailored to the needs of virtual organizations (VO) is still to be developed. Among the most popular EAM methodologies, TOGAF has been chosen as the basis for a new EAM methodology taking into account characteristics of VOs presented in this paper. In this new methodology, referred as Virtual Organization Breeding Methodology (VOBM), concepts developed within the ECOLEAD project, e.g. the concept of Virtual Breeding Environment (VBE) or the VO creation schema, serve as fundamental elements for development of VOBM. VOBM is a generic methodology that should be adapted to a given VBE. VOBM defines the structure of VBE and VO architectures in a service-oriented environment, as well as an architecture development method for virtual organizations (ADM4VO). Finally, a preliminary set of tools and methods for VOBM is given in this paper.

Game-Based Virtual Worlds as Decentralized Virtual Activity Systems  

Science.gov (United States)

There is widespread interest in the development and use of decentralized systems and virtual world environments as possible new places for engaging in collaborative work activities. Similarly, there is widespread interest in stimulating new technological innovations that enable people to come together through social networking, file/media sharing, and networked multi-player computer game play. A decentralized virtual activity system (DVAS) is a networked computer supported work/play system whose elements and social activities can be both virtual and decentralized (Scacchi et al. 2008b). Massively multi-player online games (MMOGs) such as World of Warcraft and online virtual worlds such as Second Life are each popular examples of a DVAS. Furthermore, these systems are beginning to be used for research, deve-lopment, and education activities in different science, technology, and engineering domains (Bainbridge 2007, Bohannon et al. 2009; Rieber 2005; Scacchi and Adams 2007; Shaffer 2006), which are also of interest here. This chapter explores two case studies of DVASs developed at the University of California at Irvine that employ game-based virtual worlds to support collaborative work/play activities in different settings. The settings include those that model and simulate practical or imaginative physical worlds in different domains of science, technology, or engineering through alternative virtual worlds where players/workers engage in different kinds of quests or quest-like workflows (Jakobsson 2006).
