    2007-01-01

    Full Text Available El presente “artículo de investigación” presenta algunas reflexiones sobre el “instrumento Metrovivienda” como parte de la política pública de VIS en Bogotá en las tres últimas administraciones de Peñalosa, segunda de Mockus y Garzón. Se basa en los resultados del proyecto de investigación 1879, Políticas públicas, gobernancia y territorio: el caso de la vivienda de interés social-vis en Bogotá y Chiquinquirá” , realizado por el autor en el marco del Grupo de Investigación Políticas Urbanas del Departamento de Arquitectura de la Pontificia Universidad Javeriana. Es también un “artículo de reflexión” que complementa varios artículos del mismo autor sobre los primeros resultados de esta investigación, los elementos analíticos y el marco teórico general de análisis de las políticas públicas en el territorio. El artículo se organiza así: • Unas reflexiones sobre la territorialización de la acción pública, los conceptos de gobierno y gobernancia y su relación con la instrumentación de la acción pública. • El análisis del Metrovivienda de Peñalosa como la implementación del “modelo de gestión controlada por el Estado”, en el cual “Metrovivienda es la política pública de vis”. • El análisis del Metrovivienda de Mockus como el esbozo de “un modelo ciudadano” y un instrumento, entre otros, de una política habitacional. • El análisis de las vacilaciones en cuanto al Metrovivienda de Garzón como la búsqueda de la respuesta a la cuestión ¿se puede mantener el instrumento Metrovivienda para una nueva política pública de vis? • Unas conclusiones sobre el “matrimonio indisoluble” entre iap y política pública.

  4. Inter-brain synchronization during social interaction.

    Directory of Open Access Journals (Sweden)

    Guillaume Dumas

    Full Text Available During social interaction, both participants are continuously active, each modifying their own actions in response to the continuously changing actions of the partner. This continuous mutual adaptation results in interactional synchrony to which both members contribute. Freely exchanging the role of imitator and model is a well-framed example of interactional synchrony resulting from a mutual behavioral negotiation. How the participants' brain activity underlies this process is currently a question that hyperscanning recordings allow us to explore. In particular, it remains largely unknown to what extent oscillatory synchronization could emerge between two brains during social interaction. To explore this issue, 18 participants paired as 9 dyads were recorded with dual-video and dual-EEG setups while they were engaged in spontaneous imitation of hand movements. We measured interactional synchrony and the turn-taking between model and imitator. We discovered by the use of nonlinear techniques that states of interactional synchrony correlate with the emergence of an interbrain synchronizing network in the alpha-mu band between the right centroparietal regions. These regions have been suggested to play a pivotal role in social interaction. Here, they acted symmetrically as key functional hubs in the interindividual brainweb. Additionally, neural synchronization became asymmetrical in the higher frequency bands possibly reflecting a top-down modulation of the roles of model and imitator in the ongoing interaction.

    Social class is not often discussed or examined in-depth in couple and family therapy research and literature even though social class shapes familial relationships and is considered an important variable in marital satisfaction. In this qualitative study, we explored the perceptions of eight couples who made lasting commitments across class lines by asking them about the impact of their social class backgrounds on their relationships. Three categories of themes emerged including: (a) differences and similarities in values and attitudes toward education, work, money, and class awareness/classism, (b) relationship issues involving families of origin, friends, and class-based couple conflict, and (c) differences in economic resources, social capital and privileges/opportunities. Implications for assessment and treatment of couples are included. © 2012 American Association for Marriage and Family Therapy.

  1. Frustrated Achievers or Satisfied Losers? Inter- and Intragenerational Social Mobility and Happiness in China

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available How and to what extent is rank mobility associated with happiness of the Chinese population? Does mobility provide insight into the vast numbers of frustrated workers in times of economic growth? To date, few studies have examined the consequences of social mobility on happiness in transitional societies. The present analysis investigates the association of both inter- and intragenerational rank mobility with happiness in China using data from the General Social Survey's 2003, 2006, and 2008 waves. We examine two general mechanisms, social adaptation and social comparison, by statistically decomposing the independent contributions of social origin, social destination, and mobility. We find there is a significant positive association between short-distance intragenerational downward mobility and happiness, while not any intergenerational mobility pattern has been found to be significant. Apparently, we have a group of satisfied losers. Our findings favor social comparison explanations.

  2. Resiliency to social defeat stress relates to the inter-strain social interaction and is influenced by season variation.

    Exposure to social defeat (SD) stress exerts social avoidance and depressive disorders. Little is known about the relationship between resiliency to stressors and the inter-strain social interaction (SI) level. We hypothesized that SD resiliency is correlated with a high SI between the same strain. C57BL/6J mice experienced a 10-day period of SD stress by repeated CD-1 mice offensive. The susceptible mice exhibited significant social-avoidance behaviors with less time in interaction-zone (IZ) and lower social interaction ratio (SIR) toward the Target (CD-1 mice), while resilient ones exhibited similar social interaction to control mice. When the Target was C57BL/6J mouse, either susceptible or resilient mice spent more time in IZ and the inter-strain SI in the resilient group was significantly higher than the susceptible. Correlation analysis revealed a significantly non-zero slope of the linear relationship between SIRs toward two strains. But different groups had a similar baseline of the inter-strain SI before stress, indicating a SD-induced defect in both types of SI. In addition, in four different seasons, animals exhibited a significant resiliency to the stress in summer. These data suggest that SD resiliency is related to a higher SI toward the same-strain, and may be regulated by seasonal variations. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

  3. How does social essentialism affect the development of inter-group relations?

    Psychological essentialism is a pervasive conceptual bias to view categories as reflecting something deep, stable, and informative about their members. Scholars from diverse disciplines have long theorized that psychological essentialism has negative ramifications for inter-group relations, yet little previous empirical work has experimentally tested the social implications of essentialist beliefs. Three studies (N = 127, ages 4.5-6) found that experimentally inducing essentialist beliefs about a novel social category led children to share fewer resources with category members, but did not lead to the out-group dislike that defines social prejudice. These findings indicate that essentialism negatively influences some key components of inter-group relations, but does not lead directly to the development of prejudice. © 2017 John Wiley & Sons Ltd.

  5. Empoderamiento social en contextos violentos mexicanos mediante la competencia mediática

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available En las actuales ecologías mediáticas la adquisición de saberes digitales, manejo de dieta de medios y dominios generales de las TIC son fundamentales para el desarrollo y el empoderamiento de las audiencias, en particular, al considerar los desafíos políticos y sociales de entornos como el latinoamericano. Así, el estudio de la competencia mediática es urgente para dimensionar las necesidades y características de estas comunidades. La presente investigación analiza la dimensión axiológica e ideológica de la competencia mediática durante un proceso electoral en el noroeste de México, región que se ha caracterizado por la violencia relacionada con el crimen organizado. A partir de un instrumento diseñado para evaluar dicha competencia, se seleccionaron 23 ítems que remiten a la dimensión señalada, este se aplicó por medio de un muestreo probabilístico a 385 sujetos divididos en nativos, inmigrantes y analfabetos digitales. Tras un análisis factorial exploratorio se identificaron siete factores que conforman la dimensión axiológica e ideológica. Se exploraron las puntuaciones intra e intergrupos y se encontraron puntuaciones bajas en componentes que aluden a la participación ciudadana y a la movilización social; asimismo, tres de los siete factores presentaron diferencias estadísticamente significativas, siendo los nativos digitales quienes reportaron valores más bajos. Así, se pone en evidencia la necesidad de buscar nuevas estrategias para que los ciudadanos adquieran la competencia mediática y que así el prosumo se vuelva una herramienta de empoderamiento social.

    Full Text Available Reticular Analysis of Discourse (ARD refers to a large range of techniques that intend to represent the discourse as a network of meanings. The idea is well simple: the words and/or propositions are nodes of a linguistic network that relates them, and that can be studied by Social Network Analysis (Lozares et al, 2003. This text focus on ARD from theory of argumentation within language (Anscombre and Ducrot, 1983, which introduces the relational notion of topos (plural, topoi. It is possible to represent the globally of all the topoi identifed in a discursive network that schematizes cognitive/ideological systems, a possibility already contemplated, by authors, although not developed. This text presents a methodological proposal in this direction, and samples the results from an empirical application at the study of the discourses about formation employment.

  13. Economic, social, energy and environmental assessment of inter-municipality commuting: The case of Portugal

    International Nuclear Information System (INIS)

    Ferreira, João-Pedro; Barata, Eduardo; Ramos, Pedro Nogueira; Cruz, Luis

    2014-01-01

    Commuting is one of the main contributors to the high energy consumption patterns in modern economies. The need to reduce the energy spent in commuting has attracted the attention of academics and policy makers. The main goal of this research is to improve knowledge of the economic, social, energy and environmental opportunity costs of inter-municipality commuting and to support policy-oriented strategies that explicitly take them into account. For this, we use hypothetical assumptions based on the baseline scenario that Portuguese households do not travel between municipalities for commuting purposes coupled with the expected changes in private final consumption. Accordingly, the direct, indirect and induced opportunity costs of inter-municipality commuting are assessed using an input–output model. The significance of the estimated virtual net benefits of commuting is analyzed according to their macroeconomic (GVA, taxes, international imports and employment), energy (primary energy consumption) and environmental (CO 2 emissions) dimensions. The results obtained empirically indicate that inter-municipality commuting has significant opportunity costs in the GVA and GDP as well as in primary energy consumption and CO 2 emissions. The results also indicate that commuters in metropolitan regions and long-distance commuters are responsible for a major share of these opportunity costs. - Highlights: • This paper provides an insight into the magnitude of opportunity costs of commuting. • Input–output modeling is valuable to assess changes in final consumption patterns. • About 25% of household's fuel consumption is due to inter-municipality commuting. • Inter-municipality commuting has net negative effects on GDP, GVA and employment. • The main opportunity costs come from metropolitan and long distance commuting

    Directory of Open Access Journals (Sweden)

    Katie Warfield

    2016-04-01

    Full Text Available This introduction to the special issue entitled Me-diated Inter-faces begins by bringing into question the concept of positioning: what is it that we are doing when we take a position within the study of social media? Reviewing the work of the inaugural manifestos of the journal Social Media + Society on one hand, and the introduction to the special issue on selfies for the International Journal of Communications on the other, this introduction provides both critical and creative in-roads for thinking and re-thinking digital self-images shared on social media. Given the constantly changing nature of social media, this paper is a call to researchers of social media to not fall prey to the ossification of our current positions since theorizing the “social” in social media means always at once theorizing the body. As such this intro offers numerous and diverse perspectives on the body that might inform emerging thoughts on the socially media body. The introduction then provides an overview of the papers in this special issue and concludes by offering openings and ruptures for further discussion, rather than closure of conclusions.

    Full Text Available The first part of the paper describes an approach to understanding social maturity and operational criteria for its estimation. In general, social maturity is defined as the willingness of an individual to take responsibility for developing his/her community. Social identification with broad social communities is an integral component of social maturity. The paper presents the results of the age analysis (intra-subject factor and the analysis of psycho-pedagogical conditions (inter-subject factor which facilitate the appearance of «I - person» social identity in the mental representation of a person. Inter-individual trajectory of social maturity development passes through a number of «points». At the age of 7 a person has a typical position of «I» identity; during adolescence the teenager reaches the point of the «Person» identity, whose qualities may differ from those of a child. By the age of 25 more than third of young people has acquired the «I-person» identity. Recreation of psycho-pedagogical conditions in primary schools, development of children’s cooperation, development of children’s ability to communicate with different participants of the educational process, actualization of different levels of social identity are the factors that allow to found the basis of the «I - person» identity in two thirds of the participants of the experiment. The results are stable over a long period of time (18-year. The second part represents the analysis of the specific features of mental self-representation effect on the subsequent social and psychological development of a person. Correlation analysis between the indices of the categorical structure of texts written on the same issue by the same authors at the age of 7 and then 25 years has revealed the types of empirical ways to form social maturity. These types include: «I - for the Company», «I – for others», «I - for the family,» «I –for an activity» and «I - for myself

    Full Text Available Various authors have shown the importance of collaborative relationships for inter-organizational performance, the mode of governance or the trajectory of biotechnology companies. Most of these works analyze the exclusive contractual agreements between companies and their main relationships among individuals. We show that this purely economic approach presents a major limitation: the nature of contractual relationships does not explore in detail how players cooperate. We propose to extend the study of these inter-organizational social relations, seen through the resource exchange in inter-individual. An empirical study on the leaders of the biotechnology industry in the area of human health in France has allowed us to map their relationships and resources they exchange them. Our results confirm the existence of a system of exchange dense and multiple. It presents a hierarchical distribution of various types of resources, where the centre is different from the periphery relations denser, more numerous and more reciprocal. However, comparative analysis of different networks reveals that the relationships of the board are highly centralized, while those of friendship following a more even distribution. We suggest that this phenomenon is part of a compensation mechanism to less central actors to maintain inter-organizational relationships. Finally, two standards of the cooperation process, revealed by the relational behaviour of actors, have been discovered. We suggest that they reflect in part the difficult process of adjustment that must cross a science project out of the realm of academic research and develop in a private structure: the biotech company.

    Full Text Available The inter-basin water transfer (IBWT projects have quasi-public-welfare characteristics, whose operations should take into account the water green level (WGL and social welfare maximization (SWM. This paper explores the interactions between multiple stakeholders of an IBWT green supply chain through the game-theoretic and coordination research approaches considering the government’s subsidy to the WGL improvement under the SWM. The study and its findings complement the IBWT literature in the area of the green supply chain and social welfare maximization modeling. The analytical modeling results with and without considering the SWM are compared. A numerical analysis for a hypothetical IBWT green supply chain is conducted to draw strategic insights from this study. The research results indicate that (1 If the SWM is not considered, coordination strategy could effectively improve the operations performances of the IBWT supply chain and its members, the consumers’ surplus, and the social welfare when compared with the equilibrium strategy; (2 If the SWM is considered, the IBWT green supply chain and its members have a strong intention to adopt the equilibrium strategy to gain more profits, while the government has a strong intention to encourage the IBWT green supply chain and its members to adopt the coordination strategy to maximize social welfare with a smaller public subsidy; (3 The government’s subsidy policy should be designed and provided to encourage the IBWT green supply chain and its members to improve WGL and pursue the SWM, and a subsidy threshold policy can be designed to maximize social welfare with a lower subsidy budget: only when the IBWT green supply chain and its members adopt the coordination strategy can they get a subsidy from the government.

    Full Text Available This paper tests the hypothesis that perceived differences in Mexican identity and political interest condition social well-being and the perception of anomie. The three dimensions of Tajfel’s social identity theory was adopted to measure Mexican identity, as well as the five dimensions of Keyes’s model for social well-being. A sample of 211 subjects of voting age from the State of Colima, Mexico, filled out a battery of three questionnaires and sociodemographic data. Results show that individuals with a high level of Mexican identity and political interest perceive high levels of social well-being and low level of anomie compared with those who scored low. Correlations were positive for social well-being and negative for anomie, with respect to identity and political interest. The factor of identity affirmation and identification predicted better social integration and actualization, components of social well-being.  Este estudio pone a prueba el supuesto de que las diferencias percibidas en la identidad mexicana y en el interés en la política condicionan la percepción del bienestar social y de la anomia social.

    The goals of this study were to examine intra-group and inter-group assertiveness among adolescents, and to compare these two domains of assertiveness between cultural groups in Israel. Measures of intra-group and inter-group assertiveness were developed, and questionnaires were administrated to 441 immigrants from the Former Soviet Union (FSU), 242 immigrants from Ethiopia and 333 non-immigrants. Compared to non-immigrants, FSU and Ethiopian immigrants' inter-group assertiveness was lower. Girls reported higher levels of inter-group assertiveness than boys. Each of the immigrant groups rates itself as equally assertive as the non-immigrant group and more assertive than the other immigrant group. Also, a difference between inter-group and intra-group assertiveness was found among the FSU immigrants. It is argued that adolescents' assertiveness following cultural transition is associated with socio-cultural context, and the implications of this conclusion are discussed.

    This article investigates network governance in the context of health and wellbeing services in England, focussing on relationships between managers in a range of services. There are three aims, namely to investigate, (i) the configurations of networks, (ii) the stability of network relationships over time and, (iii) the balance between formal and informal ties that underpin inter-agency relationships. Latent position cluster network models were used to characterise relationships. Managers were asked two questions, both designed to characterise informal relationships. The resulting networks differed substantially from one another in membership. Managers described networks of relationships that spanned organisational boundaries, and that changed substantially over time. The findings suggest that inter-agency co-ordination depends more on informal than on formal relationships. Copyright © 2015 Elsevier Ltd. All rights reserved.

The social intelligence indices of Portuguese students in school years prior to a career transition are characterized and intra and interindividual differences are analyzed. Participants were 1095 students (552, 50.4% women with a mean age of 14.78 years (SD = 1.86, in the 8th (542, 49.5%, 10th (295, 26.9% and 11th (258, 23.6% grades. The Cognitive Test of Social Intelligence (PCIS was administered at two moments, six months apart. Results indicate that the 8th grade obtained higher average scores in Problem Solving, Motivation and Self-confidence (time 1, while the 10th grade obtained better results in Problem Solving, Motivation and Familiarity (time 2. Between the assessment moments, all school years register an increase in Problem Solving and Self-confidence in social situations. These results constitute favorable psychological conditions for the promotion of ethical questioning in career guidance interventions.

  10. Behavioural plasticity across social contexts is regulated by the directionality of inter-individual differences.

    2017-08-01

    An individual's behavioural phenotype is a combination of its unique behavioural propensities and its responsiveness to environmental variation, also known as behavioural plasticity. In social species, we must not only explore how individuals respond to variations in the physical environment but also how they react to changes in their social environment. A growing body of work has demonstrated that the behavioural heterogeneity of a group can alter its responsiveness, decision making, and fitness. Whether an individual is more or less extreme than a partner - what we term its 'relative personality' - may also alter individual behavioural responses. We determined exploratory tendencies of individual zebrafish (Danio rerio) and then constructed pairs with varying differences in 'relative personality' to determine the effect of differences between partners on behavioural plasticity. We find that relative personality, but not the magnitude of the difference between partners, is the most important determinant of behavioural plasticity across social treatments. Despite this overall effect, pairs of fish exhibited no predictable leader-follower interactions, suggesting that details of the experimental paradigm may be important in shaping social dynamics.

    2017-01-01

    This study adopts social capital theory and transaction cost theory to explore the feasibility of an inter-organizational cross-hospital electronic medical records (EMR) exchange system, and the factors that affect its adoption. The concept of value co-creation is also used to assess such a system, and its influence on the performance of participating medical institutes. This research collected 330 valid paper-based questionnaires from the medical staff of various institutes. The results showed that social interaction ties and shared vision positively affected medical institutes' willingness to adopt the EMR exchange system, while asset specificity and uncertainty increased the related transaction costs. With a greater willingness to invest in relation-specific assets and to meet the related transaction costs, this behavior lead to an increase in medical IT value, as well as better results for the related medical institutes, medical staff, and patients. Therefore, this study suggests that such institutes encourage their medical staff to participate in seminars or reunions in order to develop their professional and social networks, and set up clear schedules and desire for expected effects when introducing the cross-hospital EMR exchange system.

  13. Neither bridging nor bonding: A test of socialization effects by ethnically diverse voluntary associations on participants' inter-ethnic tolerance, inter-ethnic trust and intra-ethnic belonging.

    van der Meer, Tom

    2016-01-01

    The distinction between bridging and bonding associations is a cornerstone of social capital research. Nevertheless, this study is the first to provide a direct test of the socialization mechanism that supposedly causes ethnically mixed (bridging) associations to generate interethnic tolerance and trust, and homogenous (bonding) associations to cement self-affirming identities. This multilevel analysis of the Citizenship, Involvement & Democracy (CID) 1999/2000 survey data on Mannheim (Germany), Enschede (the Netherlands), and Aberdeen (Scotland) covers 3166 active participants in 645 associations. The CID includes objective, exogenous measures of each association's composition and aim. Socialization and self-selection effects are pulled apart through interactions with detailed measures of associational involvement. The results display no evidence for (diverse and homogenous) associations as socializing agents. Although inter-ethnic tolerance is higher in ethnically diverse associations, this should be attributed to self-selection effects. Copyright © 2015 Elsevier Inc. All rights reserved.

  15. Does social deprivation influence inter-group contact outcomes for pupils in Northern Ireland?

    Directory of Open Access Journals (Sweden)

    Joanne Hughes

    2015-02-01

    Full Text Available The education system in Northern Ireland is characterized by division, with around 95% of the pupil population attending predominantly co-religionist schools. In a society that is transitioning from a thirty year conflict that has been framed by hostilities between the main Catholic and Protestant communities, reconciliation interventions in education have sought to promote the value of intergroup contact between pupils attending separate schools. Some qualitative research suggests that such initiatives are more likely to have positive outcomes for pupils from more middle class backgrounds than those from more disadvantaged communities and areas that experienced high levels of conflict related incidents and deaths during the pre-ceasefire years. Drawing on contact theory and empirical evidence from a large scale quantitative study, we seek to examine this theory. Using free school meals as a proxy for social class, our findings are consistent in finding that there is a differential impact of contact for those from less affluent backgrounds, and we conclude by arguing that this should be reflected in policy responses.

    Full Text Available Factors such as social change and increasing urbanization processes in the early years of the 21st century have caused a reduction in the amount of time that children devote to leisure activities in the open-air, resulting in more sedentary lifestyles than children in previous decades. An education in healthy habits from early ages to increase children’s physical and mental well-being together with their level of cultural knowledge contributes to the acquisition of a Leisure Culture that allows children to perceive the close environment as a scene for learning and enjoyment. It is thus be necessary for schools to foster pedagogical experiences, taking the physical and cultural environment as teaching resources. An innovation project is proposed which will be implemented with 25 university students from the School of Teacher Training and Education at the University of Oviedo (Oviedo, Spain. The project will consist of the proposal of educational itineraries through the city of Oviedo and Mount Naranco. As teachers-to-be, students must combine knowledge of the related areas and generate inter-disciplinary activities throughout the routes that will foster respect for the environment and leisure based on culture and physical activity, attitudes that they will transmit to their own students in the future.

    Over the past half century Brazil has undergone a process of dramatic industrialization and urbanization. Cardiovascular diseases (CVD) have become common due to rapid demographic, epidemiologic, and nutritional transitions. The association of social mobility with subclinical CVD has been rarely explored, particularly in developing societies. We investigated the association of intra- and inter-generational social mobility with carotid intima-media thickness (IMT), a marker of subclinical or asymptomatic atherosclerosis, in a large Brazilian sample (ELSA-Brasil). We used baseline data (2008-2010) for 7343 participants from ELSA-Brasil. Intra-generational social mobility was defined as the change in occupational social class between participants' first occupation and current occupation. Inter-generational social mobility was defined as the change in occupational social class of the head of the household when the participant started working and participants' current occupation. Social mobility groups were classified as: stable high (reference), upward, downward and stable low. Linear regression models were used to examine the associations between type of social mobility and IMT. Compared to those who experienced stable high occupational status across generations, downward inter-generational mobility was associated with greater IMT. Additionally, those who declined the most in occupational status had the highest values of IMT, even after adjustments for lifestyle and cardiovascular factors. For intra-generational mobility, stable low versus stable high social mobility was independently associated with higher IMT. Subclinical atherosclerosis is patterned by socioeconomic status both within and across generations, demonstrating an association even before symptoms of CVD appear. The health consequences of downward inter-generational social mobility were not fully explained by lifestyle and cardiovascular factors, whereas being consistently exposed to low occupational

    Participation in population-based preventive health check has declined over the past decades. More research is needed to determine factors enhancing participation. The objective of this study was to examine the association between two measures of neighborhood level social capital on participation in the health check phase of a population-based lifestyle intervention. The study population comprised 12,568 residents of 73 Danish neighborhoods in the intervention group of a large population-based lifestyle intervention study - the Inter99. Two measures of social capital were applied; informal socializing and voting turnout. In a multilevel analysis only adjusting for age and sex, a higher level of neighborhood social capital was associated with higher probability of participating in the health check. Inclusion of both individual socioeconomic position and neighborhood deprivation in the model attenuated the coefficients for informal socializing, while voting turnout became non-significant. Higher level of neighborhood social capital was associated with higher probability of participating in the health check phase of a population-based lifestyle intervention. Most of the association between neighborhood social capital and participation in preventive health checks can be explained by differences in individual socioeconomic position and level of neighborhood deprivation. Nonetheless, there seems to be some residual association between social capital and health check participation, suggesting that activating social relations in the community may be an avenue for boosting participation rates in population-based health checks.

    This study investigates the migration intentions of current and future knowledge-workers in Saxony, Germany. A structural equation model (SEM) is applied to analyze the impact of social networks and norms on inter-regional migration, in addition to lifestyle and utilitarian location factors....... The dataset comprises 2731 young knowledge workers. The results show that: (i) migration intentions positively associate with social networks in other cities, subjective norms that West-is better than East-Germany, and that other regions provide better life opportunities; (ii) staying intentions positively...... relate to having origins, close friends and family in Saxony, and positive consideration of Saxony as an option by the parent; (iii) the structure of the social networks and norms is related to socio-economic characteristics, travel habits, and on-line social networks.

    Full Text Available The article revisits spatial interaction and distance decay from the perspective of human mobility patterns and spatially-embedded networks based on an empirical data set. We extract nationwide inter-urban movements in China from a check-in data set that covers half a million individuals within 370 cities to analyze the underlying patterns of trips and spatial interactions. By fitting the gravity model, we find that the observed spatial interactions are governed by a power law distance decay effect. The obtained gravity model also closely reproduces the exponential trip displacement distribution. The movement of an individual, however, may not obey the same distance decay effect, leading to an ecological fallacy. We also construct a spatial network where the edge weights denote the interaction strengths. The communities detected from the network are spatially cohesive and roughly consistent with province boundaries. We attribute this pattern to different distance decay parameters between intra-province and inter-province trips.

  9. Social familiarity governs prey patch-exploitation, -leaving and inter-patch distribution of the group-living predatory mite Phytoseiulus persimilis.

    In group-living animals, social interactions and their effects on other life activities such as foraging are commonly determined by discrimination among group members. Accordingly, many group-living species evolved sophisticated social recognition abilities such as the ability to recognize familiar individuals, i.e. individuals encountered before. Social familiarity may affect within-group interactions and between-group movements. In environments with patchily distributed prey, group-living predators must repeatedly decide whether to stay with the group in a given prey patch or to leave and search for new prey patches and groups. Based on the assumption that in group-living animals social familiarity allows to optimize the performance in other tasks, as for example predicted by limited attention theory, we assessed the influence of social familiarity on prey patch exploitation, patch-leaving, and inter-patch distribution of the group-living, plant-inhabiting predatory mite Phytoseiulus persimilis. P. persimilis is highly specialized on herbivorous spider mite prey such as the two-spotted spider mite Tetranychus urticae, which is patchily distributed on its host plants. We conducted two experiments with (1) groups of juvenile P. persimilis under limited food on interconnected detached leaflets, and (2) groups of adult P. persimilis females under limited food on whole plants. Familiar individuals of both juvenile and adult predator groups were more exploratory and dispersed earlier from a given spider mite patch, occupied more leaves and depleted prey more quickly than individuals of unfamiliar groups. Moreover, familiar juvenile predators had higher survival chances than unfamiliar juveniles. We argue that patch-exploitation and -leaving, and inter-patch dispersion were more favorably coordinated in groups of familiar than unfamiliar predators, alleviating intraspecific competition and improving prey utilization and suppression.

    Full Text Available Bridging social capital through sports: an explorative study on (improving inter-ethnic contact at two soccer clubs in the NetherlandsIn the Netherlands, the social integration of minorities has been the subject of much debate in recent years. Historical events such as the murders of politician Pim Fortuyn and writer Theo van Gogh, and more recently the emergence of organizations such as Islamic State (IS, have had a major impact on public debate in the Netherlands. Nevertheless, belief in the socially integrative role of sport has increased. Sport, especially formal participation in sport, is expected to contribute positively to social cohesion and the social integration of minorities. Nonetheless, existing research shows that policymakers overestimate the impact of sport on social integration in society. Sport is no panacea. Sport can include people, but it can also exclude them by bringing together those who “look alike”. In this article we explore whether (and how sport, and in particular soccer, can lead to bridging social capital, despite the fact that people generally prefer to congregate with “equals”. We base our results on questionnaires and a limited number of additional interviews at two soccer clubs in the city of Utrecht in the Netherlands. We conclude that although sport can reinforce segregation, formal participation in sport also has the ability to enhance social inclusion and inter-ethnic contacts. The research indicates that measures could be taken in order to promote understanding and respect.Overbruggend sociaal kapitaal door middel van sport: Een exploratief onderzoek naar (het verbeteren van inter-etnische contacten bij twee voetbalverenigingen in NederlandIn Nederland staat de sociale integratie van minderheden de laatste jaren ter discussie.

    2011-05-01

    Full Text Available The context of public policies undergoes a process of rapid change due to the emergence of the dynamic knowledge-based economy and society. Public administration institutions need to adapt their material and human resources to the dynamic developments of the knowledge and information society in order to maintain efficiency and effectiveness of their scopes. One of the most fragile fields is public order and the need for improved inter-institutional cooperation at national, regional, and EU-level for achieving the objectives of ensuring citizens’ safety while safeguarding rights and liberties. The social and economic efficiency of public order policies and measures need to be reassessed and improved based on overhauled and updated inter-institutional and organisational concepts, on diversified methods of cooperation at national, regional, EU- and international level. A recent project developed in the field of public order with respect to juvenile delinquency has shown that major questions still need to be approached with respect to efficiency and effectiveness of inter-institutional cooperation with both public and private bodies, and with representatives of the non-governmental organizations. The outcomes of the project have shown that juvenile delinquency must be approached as phenomenon in the wider framework of public order, of urban and rural safety, of crime prevention and combating. One major conclusion of the project is that a new integrated model is required with respect to the intra-, and inter-institutional cooperation and dialogue, but also with respect to the skills required to work efficiently considering the challenges posed by the overall developments of a society changing towards increased knowledge and information awareness. This would allow also for improved quality assessment and effectiveness measurements based on composite process and outcome indicators for public order, and public administration, in general, as well.

    As inter-hospital alliances have become increasingly popular in the healthcare sector, it is important to understand the challenges and benefits that the interaction between representatives of different hospitals entail. A prominent example of inter-hospital alliances are certified 'trauma networks', which consist of 5-30 trauma departments in a given region. Trauma networks are designed to improve trauma care by providing a coordinated response to injury, and have developed across the USA and multiple European countries since the 1960s. Their members need to interact regularly, e.g. develop joint protocols for patient transfer, or discuss patient safety. Social capital is a concept focusing on the development and benefits of relations and interactions within a network. The aim of our study was to explore how social capital is generated and used in a regional German trauma network. In this qualitative study, we performed semi-standardized face-to-face interviews with 23 senior trauma surgeons (2013-14). They were the official representatives of 23 out of 26 member hospitals of the Trauma Network Eastern Bavaria. The interviews covered the structure and functioning of the network, climate and reciprocity within the network, the development of social identity, and different resources and benefits derived from the network (e.g. facilitation of interactions, advocacy, work satisfaction). Transcripts were coded using thematic content analysis. According to the interviews, the studied trauma network became a group of surgeons with substantial bonding social capital. The surgeons perceived that the network's culture of interaction was flat, and they identified with the network due to a climate of mutual respect. They felt that the inclusive leadership helped establish a norm of reciprocity. Among the interviewed surgeons, the gain of technical information was seen as less important than the exchange of information on political aspects. The perceived resources derived from

    In diffuse forest uses, like non-timber forest products' harvesting, the behavioural alignment of pickers is crucial for avoiding a "tragedy of the commons". Moreover, the introduction of policy tools such as a harvest permit system may help in keeping the activity under control. Besides the official enforcement, pickers' engagement may also derive from the perceived legitimate decision of forest managers and the community pressure to behave according to the shared values. Framed within the social capital theory, this paper examines three types of relations of rural communities in a protected area in Catalonia (Spain) where a system of mushroom picking permits was recently introduced. Through social network analysis, we explore structural changes in relations within the policy network across the policy conception, design and implementation phases. We then test whether social links of the pickers' community relate to influential members of the policy network. Lastly, we assess whether pickers' bonding and bridging structures affect the rate of permit uptake. Our results show that the high degree of acceptance could be explained by an adequate consideration of pickers' preferences within the decision-making group: local pickers show proximity to members of the policy network with medium-high influence during the three policy phases. The policy network also evolves, with some members emerging as key actors during certain phases. Significant differences are found in pickers' relations among and across the involved municipalities following an urban-rural gradient. A preliminary relation is found between social structures and differential pickers' engagement. These results illustrate a case of positive social capital backing policy design and, probably, also implementation. This calls for a meticulous design of forest policy networks with respect to communities of affected forest users. Copyright © 2016 Elsevier Ltd. All rights reserved.

Las cooperativas de crédito, como organizaciones singulares en nuestro sistema financiero, poseen unos intangibles de características particulares. Así, la reputación corporativa, las relaciones sociales, con la administración o con los medios de comunicación y el ejercicio de la responsabilidad social les confieren unas características específicas y unos rasgos concretos que merecen ser estudiados. Mediante el análisis Delphi, este trabajo trata de identificar las singularidades del capital social de estas entidades, donde destacan –como fortalezas- una gran proximidad y la participación del socio y -como debilidad- la reputación de estas entidades.

    India has been the focus of many health surveys among normal, physically, and mentally handicapped children. However, the data, concerning oral health conditions of socially handicapped children living in orphanages, are scanty. To study the effect of parental inadequacy, environmental deprivation, and emotional disturbances on dental caries through intelligence quotient (IQ) and self-concept in orphan children and also to co-relate dental caries with different levels of IQ and self-concept. The study was carried out amongst socially handicapped children living in orphanages. 100 children in the age group of 10-14 years from orphanages were selected. Malin's Intelligence Scale for Indian Children (MISIC) was used to assess the intelligence quotient; self-concept questionnaire to assess self-concept of the child and recording of dental caries status of children was done as per WHO Index (1997). To assess the relationship of dental caries with IQ, student's unpaired t-test was used and; to find the relationship between self-concept and dental caries, Karl-Pearson's coefficient of co-relation was applied. the children in orphanages had a lower IQ and high caries experience but had an above average self-concept. There was also no co-relation between dental caries and self-concept. Orphan children, being socially handicapped, are at an increased risk for dental caries due to a lower IQ level, parental deprivation, and institutionalization. Moreover, lack of co-relation between dental caries and self-concept could be explained by the fact that dental caries is a lifelong process whereas different dimensions of self-concept are in a state of constant flux.

Nevertheless, and despite the reforms undertaken on it in an attempt to adapt this Policy to the reality, the CAP has been widely criticized for its low efficiency, particularly because it has not been able to integrate the social preferences related to agriculture. This paper tries to contribute to implement adequate analytical tools for the identification and quantification of citizens preferences toward agriculture and of citizens´ satisfaction reported by this activity, and to clarify whether the policymakers of the European Union have integrated into the new Common

    Full Text Available O estudo analisa aspectos macro e micro estruturais das parcerias mantidas pelas organizações do Consórcio Social da Juventude em Salvador - CSJ/RMS. A noção "redes sociais" é utilizada como ferramenta teórico-metodológica e como articulações para efetivar projetos sociais. O instrumento abrangeu questões de mapeamento da rede, recursos trocados e impactos para desempenho organizacional. Delinearam-se dois níveis de análise: Rede Geral, parcerias entre diversos setores, e Rede Consórcio, parcerias entre integrantes do CSJ. A Rede Geral apresentou-se totalmente interconectada e existem conectores centrais externos ao CSJ exercendo papel de suporte financeiro. A Rede Consórcio apresentou-se fragmentada; com baixa densidade nas relações; alta concentração de poder ou dependência em atores específicos; percepção de impacto no desempenho nas organizações com mais parcerias. Este trabalho evidencia a complexidade dos arranjos institucionais nas ações sociais, os impactos dos padrões de articulação no CSJ e nas organizações e o potencial investigativo da teoria de Redes Sociais.This study analyzes aspects of the partnerships done by the organizations of the Consórcio Social da Juventude (The Youth Social Partnership in Salvador- CSJ/RMS. The notion of social networks is used as a theoretical and methodological tool and associative arrangements to social projects. The survey covered questions about network mapping, exchanged resources and impact to the organizational performance. Two level of analysis were outlined: the General Network and the Youth Social Partnership Network . The General Network proved to be totally interconnected there being connectors external to CSJ performing financial support role. The Youth Social Partnership Network proved to be fragmented, with low density, high power concentration or dependence on actors, perception of the impact to the performance of the organizations with more connections

  10. How People Use Social Information to Find out What to Want in the Paradigmatic Case of Inter-temporal Preferences.

    Full Text Available The weight with which a specific outcome feature contributes to preference quantifies a person's 'taste' for that feature. However, far from being fixed personality characteristics, tastes are plastic. They tend to align, for example, with those of others even if such conformity is not rewarded. We hypothesised that people can be uncertain about their tastes. Personal tastes are therefore uncertain beliefs. People can thus learn about them by considering evidence, such as the preferences of relevant others, and then performing Bayesian updating. If a person's choice variability reflects uncertainty, as in random-preference models, then a signature of Bayesian updating is that the degree of taste change should correlate with that person's choice variability. Temporal discounting coefficients are an important example of taste-for patience. These coefficients quantify impulsivity, have good psychometric properties and can change upon observing others' choices. We examined discounting preferences in a novel, large community study of 14-24 year olds. We assessed discounting behaviour, including decision variability, before and after participants observed another person's choices. We found good evidence for taste uncertainty and for Bayesian taste updating. First, participants displayed decision variability which was better accounted for by a random-taste than by a response-noise model. Second, apparent taste shifts were well described by a Bayesian model taking into account taste uncertainty and the relevance of social information. Our findings have important neuroscientific, clinical and developmental significance.

  11. 'Hooligans' abroad? Inter-group dynamics, social identity and participation in collective 'disorder' at the 1998 World Cup Finals.

    2001-09-01

    During the 1998 Football World Cup Finals in France, English supporters were, once again, involved in major incidents of collective 'disorder'. Explanations for these incidents concentrated on the conflictual norms held by 'hooligans'. In contrast, Scottish supporters attending the tournament displayed norms of non-violence, explained by the popular press in terms of the absence of 'hooligans'. This study challenges this tendency to explain the presence or absence of 'disorder' in the context of football solely in terms of the presence or absence of 'hooligan' fans. Using data obtained from an ethnographic study of both Scottish and English supporters attending the tournament (N = 121), we examine the processes through which ordinarily 'peaceful' supporters would or would not become involved in collective conflict. In line with the Elaborated Social Identity Model (ESIM) of crowd behaviour, the analysis highlights the role of the intergroup context. Where out-group activity was understood as illegitimate in in-group terms, in-group members redefined their identity such that violent action toward out-group members came to be understood as legitimate. By contrast, where there was no out-group hostility, in-group members defined themselves through an explicit contrast with the 'hooligan' supporters of rival teams. This analysis represents an advance on previous studies of crowd behaviour by demonstrating how the ESIM can account for not only the presence, but also the absence, of collective 'disorder'.

    Full Text Available La vivienda social se asocia generalmente con una construcción de bajo nivel de calidad. Sin embargo, es importante contar con elementos objetivos para verificar esta afirmación. El control de la obra terminada es una medida de calidad. Este trabajo presenta el análisis de los problemas encontrados en un proyecto de interés social típico, financiado por el programa Minha Vida, Minha Casa y construido en Sao Leopoldo, Brasil. Se acompañó la obra por seis meses en su fase final de ejecución. Se consultaron los reportes de inspección de obra terminada y se realizaron observaciones directas en la obra. La primera inspección de entrega alcanzó una reprobación de los propietarios alrededor del 64%. En algunos casos se hicieron cuatro inspecciones hasta la aceptación de la unidad. A partir de los datos del estudio y del análisis realizado, las carpinterías y los revestimientos de cerámicos se revelaron como la mayor fuente de fallos, alcanzando más del 77% de los problemas señalados en las inspecciones. Se encontró que los fallos detectados se debieron a problemas con la mano de obra y falta de calidad en materiales y componentes utilizados, así como hubo supervisión insuficiente de los servicios. Se observó que hay necesidad de mejorar el control de calidad, aunque la constructora tenga un certificado PBQP-H (certificación brasileña similar a la ISO 9000. Los procedimientos adecuados se definieron en los documentos internos, pero no se siguieron

    Full Text Available Universities are beginning to promote policies aimed at eliminating discrimination, promoting spaces for community, social and educational participation. Therefore, the incorporation of college students to their academic discourse community is encouraged, since they are young people with a particular history and complex social life, which are included in different ways into the educational system. The overall purpose is to assess the intercultural resource "rap" in the academic practice of textual compositions by new students in the Extensión Región Centro- Sur of the Universidad de Oriente. In this qualitative research, the content analysis is used to account for the experiences of eight key informants interviewed, students of Industrial Engineering or Systems Engineering. It is intended to understand the reasons for the behavior of these students, analyzing both the thematic as the overall quality of writing, the reality in which they arise, and how they express their living experiences. The findings indicate that, despite the difficulties in the writing of texts: a students, in addition to reporting, are identified with this musical style, because its main purpose lies in provoking reactions, b the strategy allows to cater a heterogeneous population academically and culturally, c university students may recognize, as any artistic expression, musical text resulting from this interpretation, which has a social impact in a given group of persons. This strategy provides an opportunity to reflect on the process of integral development and deepens in the construction of a new model of society

    2013-12-01

    Full Text Available Con base en el artículo 23 de la Ley 222 de 1995, el cual establece los deberes generales de los administradores de sociedades en Colombia, se analiza un tema de especial interés para el derecho de sociedades: los conflictos de intereses, específicamente la autocontratación, toda vez que resulta ser una herramienta muy útil pero a la vez muy peligrosa para las compañías debido al poder que tienen los administradores en este tipo de transacciones. De esta manera y del artículo en mención surge el deber de lealtad como mecanismo de protección del interés social, pues obliga a los administradores a hacerlo prevalecer frente a cualquier interés personal de sus administradores o extrasociales. Sin embargo, para comprender y delimitar el alcance del deber referido es necesario analizar por un lado el concepto de interés social entendido en sus dos acepciones más importantes: la teoría contractualista y la teoría pluralista. Por el otro lado, la naturaleza de la relación entre los administradores y las sociedades a su cargo permite llenar los vacíos legales que se presenten en los casos de autocontratación. La finalidad, entonces, propuesta con este artículo es establecer la relación de todos estos elementos, esto es, deber de lealtad, interés social, naturaleza de la relación administrador-sociedad y la autocontratación.

    Full Text Available Este estudio indaga el grado de segregación residencial en los municipios que han albergado la construcción de 121 conjuntos de vivienda social, edificados en el arco nororiente del Valle de México durante el decenio 2000-2010, así como las variaciones en el grado de accesibilidad de los propios conjuntos urbanos en el mismo periodo. Mediante indicadores de accesibilidad, de autocorrelación espacial, y la contabilización de la oferta y demanda de vivienda social, se concluye que existe un alto grado de segregación en estos conjuntos residenciales y los municipios que los albergan con respecto a los municipios centrales del Valle de México; que esta segregación tiende a reducirse mínimamente con el paso del tiempo para algunas de las variables estudiadas; y que la sobreoferta de vivienda social puede haber favorecido la segregación residencial en escala metropolitana.

    Full Text Available O direito de propriedade, antigamente considerado ilimitado, foi gradualmente vinculado a uma finalidade social e ambiental. Os objetivos deste texto são: estudar o conceito, conteúdo, limites e possibilidade de aplicação prática do princípio da função social da propriedade urbana; apresentar os principais diplomas legais; constatar se o conceito abrange a proteção ambiental. A Constituição Federal de 1988 condicionou o direito de propriedade ao cumprimento de uma função social, a ser disciplinada pelos planos diretores municipais. O meio ambiente ecologicamente equilibrado foi tido como direito fundamental. A Lei n. 10.257/2001 possibilitou a aplicação prática do princípio. O vigente código civil previu a destinação social da propriedade e a obediência às normas ambientais. Foi concluído ser possível aferir, concretamente, se uma propriedade urbana cumpre sua função social, havendo, inclusive, possibilidade de imposição de penalidades em caso de descumprimento. Entretanto, para essa finalidade, o conteúdo desse conceito não abrange aspectos ambientais, mas apenas parâmetros urbanísticos de aproveitamento do solo.

    Full Text Available Music tells us through lifetime how societies are in a specific times and spaces. It is shout, denounce, identity, culture, union; it is youth and revolt. Each generation has its own music, which expresses the vision of its city, its country, and the world. Also, each urban tribe or young musical group has their own music, which gives them identity markers and cohesion. This article will undertake a case study where applied social research through music has been proven useful to break social borders and to empower the youngest people with limited resources in the Metropolitan Zone of Mexico City. Being offered a learning space, and opportunities of professionalization and self-expression young displaced may coexist with young people with better opportunities, thus affecting the reconstruction of the social network.

    La música a través del tiempo nos cuenta cómo es una sociedad en una época y espacio determinado. Es grito, denuncia, identidad, cultura, unión; es juventud y rebeldía.

Igualmente, cada grupo juvenil o tribu urbana tiene su propia música, que los identifica y cohesiona. Este artículo abordará un estudio de caso donde la investigación social aplicada ha logrado, por medio de la música, romper las fronteras sociales y potencializar las habilidades de los jóvenes de escasos recursos en la zona metropolitana de la Ciudad de México, brindándoles un espacio de aprendizaje, profesionalización y expresión donde coinciden y conviven con jóvenes con mayores oportunidades, incidiendo así en la reconstrucción del tejido social.

Para ello se utilizan dos formatos (tarjetas y computerizado de la tarea Stroop emocional. El primer objetivo es comparar estos dos formatos en un grupo de personas diagnosticadas de fobia social (n = 31 y en un grupo control normal (n = 31. El segundo objetivo es examinar si el sesgo atencional se produce en un nivel automático o estratégico, utilizando una tarea Stroop con enmascaramiento retroactivo. El tercer objetivo es analizar la relación entre variables clínicas relevantes y la presencia del sesgo atencional. Por último, se estudia si el tratamiento cognitivo-comportamental logra reducir estos sesgos. Los resultados obtenidos indican diferencias entre ambos formatos, obteniéndose resultados a favor de la hipótesis del sesgo atencional en el caso del formato de tarjetas, pero no en el computerizado. Además, no se encuentra evidencia de un sesgo atencional cuando se utiliza enmascaramiento retroactivo. En cuanto a las variables clínicas, los resultados indican que el grado de evitación de la conducta objetivo juega un papel importante en la manifestación del sesgo atencional, y que éste se reduce cuando el tratamiento es eficaz.

    Simoes, E; Hildenbrand, S; Rieger, M A

    2012-07-01

    Social medicine deals with the specific interactions between medicine and society within a constantly changing social environment. The Institute of Occupational and Social Medicine, University Hospital Tuebingen, focuses on this relationship within the academic teaching of the Medical Faculty. Many of the issues thus directly affect the national health objectives and especially the health targets of the state of Baden-Württemberg, summarised in the Health Strategy Baden-Wuerttemberg. In addition to the recommendations of the German Society for Social Medicine and Prevention (DGSMP) for the social medicine curriculum and the specific definition of the content by the Tuebingen medical faculty, national and regional health-care goals are also taken into account in the teaching conception. Classes are increasingly offered as training courses in small groups (seminars, group work with practical training), instead of classic lectures. These teaching methods allow the students to take part more actively in social medicine issues and to think and act within a comprehensive understanding of health management based on societal goals and the needs of a good health system. The concept is supported by the curriculum design element "log-book skills" of the Medical Faculty of Tuebingen. Feedback elements for teachers and students shape the further development of the concept. In dealing with real system data, practical experience on site and case vignettes, the students experience the links between societal influences, political objectives and medical action as well as the importance of accessibility of medical services for equity in health chances. The fact that advice and expertise play a crucial role in accessibility is a component to which too little attention is paid and calls for emphasis in the teaching concept. This teaching approach will deepen the understanding of the influence of psychosocial context factors and the conditions of the structural framework on the medical

  12. Does Competition Really Bring Out the Worst? Testosterone, Social Distance and Inter-Male Competition Shape Parochial Altruism in Human Males

    2014-01-01

    Parochial altruism, defined as increased ingroup favoritism and heightened outgroup hostility, is a widespread feature of human societies that affects altruistic cooperation and punishment behavior, particularly in intergroup conflicts. Humans tend to protect fellow group members and fight against outsiders, even at substantial costs for themselves. Testosterone modulates responses to competition and social threat, but its exact role in the context of parochial altruism remains controversial. Here, we investigated how testosterone influences altruistic punishment tendencies in the presence of an intergroup competition. Fifty male soccer fans played an ultimatum game (UG), in which they faced anonymous proposers that could either be a fan of the same soccer team (ingroup) or were fans of other teams (outgroups) that differed in the degree of social distance and enmity to the ingroup. The UG was played in two contexts with varying degrees of intergroup rivalry. Our data show that unfair offers were rejected more frequently than fair proposals and the frequency of altruistic punishment increased with increasing social distance to the outgroups. Adding an intergroup competition led to a further escalation of outgroup hostility and reduced punishment of unfair ingroup members. High testosterone levels were associated with a relatively increased ingroup favoritism and also a change towards enhanced outgroup hostility in the intergroup competition. High testosterone concentrations further predicted increased proposer generosity in interactions with the ingroup. Altogether, a significant relation between testosterone and parochial altruism could be demonstrated, but only in the presence of an intergroup competition. In human males, testosterone may promote group coherence in the face of external threat, even against the urge to selfishly maximize personal reward. In that way, our observation refutes the view that testosterone generally promotes antisocial behaviors and

    Science.gov (United States)

    Lippényi, Zoltán; Gerber, Theodore P

    2016-07-01

    We propose a theoretical model of how occupational mobility operates differently under socialism than under market regimes. Our model specifies four vertical dimensions of occupational resources-power, education, autonomy, and capital-plus a horizontal dimension consisting of linkages among occupations in the same economic branch. Given the nature of state socialist political-economic institutions, we expect power to exhibit much stronger effects in the socialist mobility regime, while autonomy and capital should play greater stratifying roles after the market transition. Education should have stable effects, and horizontal linkages should diminish in strength with market reforms. We estimate our model's parameters using data from surveys conducted in Hungary during and after the socialist period. We adopt a micro-class approach, though we test it against approaches that use more aggregated class categories. Our model provides a superior fit to other mobility models, and our results confirm our hypotheses about the distinctive features of the state socialist mobility regime. Mobility researchers often look for common patterns characterizing mobility in all industrialized societies. Our findings suggest that national institutions can produce fundamentally distinct patterns of mobility. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available La recuperación de los centros urbanos es una tarea a la que se han abocado los gobiernos de países de América Latina desde hace algunos años y que sigue a la tendencia implantada desde Europa y Estados Unidos. Los mayores costos del desarrollo periurbano y el elevado deterioro de los sectores centrales de las ciudades con la consecuente subutilización de recursos de infraestructura ha despertado un renovado interés por potencializar el desarrollo de estas áreas. En el corazón urbano de la ciudad de Guayaquil se encuentran importantes ejes viales como las calles Quito y Machala. Existen, sin embargo, a lo largo de estas vías solares vacíos, edificaciones obsoletas o en desuso, destinos comerciales no compatibles con la dinámica urbana, ausencia de áreas verdes e inseguridad. El objetivo del presente artículo fue analizar estrategias e instrumentos de gestión territorial que pudieran ser aplicables para la recuperación de plusvalías y el financiamiento de proyectos de vivienda social en el centro de Guayaquil. Se planteó la hipótesis de que a través de la utilización de estos instrumentos se podrían atraer inversiones al centro, y al mismo tiempo asegurar la inclusión de vivienda social, mejorar la calidad de los espacios públicos y contribuir a recuperar la memoria histórica del centro. La metodología utilizada surge de conceptualizaciones, estudio de casos y análisis de aplicabilidad de instrumentos de gestión para la renovación urbana del centro. Se concluye con una reflexión acerca de cómo las visiones diversas de la ciudad (la de las elites y de los grupos de menores ingresos pueden y deben ser integradas, por medio de la aplicación de instrumentos de recuperación de plusvalías enmarcados dentro de la discusión del derecho a la vivienda, la ciudad y a la función social de la propiedad.

    Full Text Available Crocodylus moreletii representa un emblema para los ecosistemas tropicales de México pero actualmente está amenazada por extinción. Sorprendentemente, hay una falta de información de su constitución genética, que debe ser evaluada para un manejo apropiado ex situ y para toma de decisiones en la liberación de cocodrilos a su hábitat natural. El objetivo del estudio fue caracterizar y comparar la variabilidad genética de cuatro grupos poblacionales de C. moreletii (dos silvestres y dos nacidas ex situ. Mediante PCR se amplificaron siete loci de microsatélites polimórficos, sin embargo se encontró déficit de heterocigotos en las poblaciones (promedio H O=0.02 mermado por la presencia de alelos nulos. El AMOVA indicó que la mayor proporción de variabilidad genética se encuentra dentro de las poblaciones y una limitada diferenciación genética entre poblaciones (promedio F ST =0.03, probablemente debida al alto índice de endogamia (promedio F IS=0.97. Al comparar la variabilidad genética inter e intra especies de cocodrilianos, encontramos que en C. moreletii está muy por debajo de los reportados. Se concluye que la limitada variabilidad genética de las poblaciones nacidas ex situ probablemente se debe al efecto fundador derivado de la estructura social de sus progenitores, y de las poblaciones silvestres, por el efecto cuello de botella, inferido por el limitado tamaño efectivo de población que presentó históricamente en su distribución natural.

    Full Text Available The essay explicates the phenomenological problematic of intersubjectivity on the level of bodily interaction with the world and with others. On this level, the concept of visibility is transformed in terms of the primacy of bodily “I can” and the kinaesthetic awareness that pervades all perceptual fields. In addition, the investigations into kinaesthetic awareness lead to the understanding that one’s own bodily action is extended as well as varied by the kinaesthetic activities of others and thus form an inter-corporeal field wherein visibility is located. Such an extended awareness is the bodily counterpart of transcendental domain.

The developing countries accuse the developed countries of waking use of this speech as form to protect their domestic markets. The arguments of both are reasonable, therefore, it is necessary to find an term intermediate, that interrelates OIT and OMC in the direction of protecting the involved workers in the process of production for the international market, at the same time, that it hinders the developed countries of tanking advantage of the social clause to impose protectionistic barriers, harming the developing countries.A inclusão de cláusula social no âmbito da OMC, como forma de eliminar condições de trabalho degradantes nos países em desenvolvimento, é tema que vem sendo exaustivamente discutido dentro das relações internacionais do comércio.

    In this article a thermal-environmental study is presented in order to evaluate the energy demand in the Morelos state. From collected climatologic data in seven automatic weather stations a comparative diagnosis by the application of two methodologies is realized, such as the one of the Degrees-day and the transitory thermal simulation of TRNSYS to determine the energy demand in traditional dwellings of social interest located in different regions of the State. In the methodology of the degrees-day the ambient temperature for two seasons of the year is used (rainy and dry) and the energy demand for the comfort in the Morelos State is evaluated. For the thermal simulation with the TRNSYS the climatic data obtained in monthly averages is used to determine the thermal loads of the house and the energy requirements in the different regions of the State. The results of the energy demand obtained by both methodologies for the municipality of Jiutepec and a statistic analysis of the existing relation between the degrees-day of cooling and the energy demand for cooling that the dynamic simulations deliver are presented.

    Full Text Available The present study investigated the developmental foundation of the relation between social essentialism and attitudes. Forty-eight Jewish Israeli secular 6-year-olds were exposed to either a story emphasizing essentialism about ethnicity, or stories controlling for the salience of ethnicity or essentialism per se. After listening to a story, children’s attitudes were assessed in a drawing and in an IAT task. Compared to the control conditions, children in the ethnic essentialism condition drew a Jewish and an Arab character as farther apart from each other, and the Jewish character with a more positive affect than the Arab character. Moreover, boys in the ethnic essentialism condition manifested a stronger bias in the IAT. These findings reveal an early link between essentialism and inter-group attitudes.

    2013-01-01

    Chapter 11 by Kirsten Halskov Madsen, Anette Meldgaard and Jette Henriksen deals with the development of palliative care programmes aimed at the basic level of palliative care practice. The need to develop educational opportunities at particularly this level – described as ‘the basic inter......-professional level of palliative care’ – has been increasing for many years where palliative care has conventionally and primarily been associated with specialist training. As the authors show – based on a mapping out of existing educational initiatives in a region of Denmark, a reading of the curriculum...... and a description of the organization of palliative care – there is a need for such inter-professional palliative care that raises the level of competences at the basic level and the sharing of knowledge as well as securing the continuous qualifying of healthcare staff working with palliative care....

  8. Barriers of inter-organisational integration in vocational rehabilitation.

    2008-06-19

    A project of vocational rehabilitation was studied in Sweden between 1999 and 2002. The project included four public organisations: the social insurance office, the local health services, the municipal social service and the office of the state employment service. The aim of this paper was to analyse perceived barriers in the development of inter-organisational integration. Theories of inter-professional and inter-organisational integration, and theories on organisational change. In total, 51 semi-structured interviews and 14 focus group discussions were performed with actors within the project between 1999 and 2002. A thematic approach was used for the analysis of the data. THREE DIFFERENT MAIN THEMES OF BARRIERS EMERGED FROM THE DATA: A Uncertainty, B Prioritising own organisation and C Lack of communication. The themes are interconnected in an intricate web and hence not mutually exclusive. The barriers found are all related partly to organisational change in general and partly to the specific development of organisational integration. Prioritising of own organisation led to flaws in communication, which in turn led to a high degree of uncertainty within the project. This can be seen as a circular relationship, since uncertainty might increase focus on own organisation and lack of communication. A way to overcome these barriers would be to take the needs of the clients as a point of departure in the development of joint services and to also involve them in the development of inter-organisational integration.

  15. Improving inter-transmission compensation in EU

    International Nuclear Information System (INIS)

    Stoilov, Dimo; Stoilov, Luben

    2013-01-01

    This article is intended as a roadmap to the correction of the existing shortcomings in the EU power transmission tariff system, especially in the existing mechanism of Inter-Transmission System Operator (TSO) Compensation (ITC). The relevant literature is surveyed and the essence of the issue is formulated. Definitions, preconditions, assumptions and constraints for the problem are explained. The paper outlines the most simple and straightforward approach for the improvement of inter-transmission compensation in the Continental European Synchronous Area. The proposals are based on the old practice of socialization of the network costs retained in almost all European countries, i.e. the principle of charging the customers “at the exit”. Equal treatment is given to internal users and cross-border users: a TSO is reimbursed for both internal and cross-border flows from the users conjoined to its network on an equal footing with the users extracting power from the peripheral nodes. The existing inequity in individual payments for power transmission is overcome and the cross-border subsidy element is avoided. This approach should be tested (modeled and evaluated) with real data for the European union of networks. Some key parts of the article are written in a more popular style, in order to be accessible to inexpert readers as well. -- Highlights: •A roadmap to the correction of the shortcomings in the EU power transmission tariff system. •Simple and straightforward approach for improvement of ITC in the European synchronous area. •Equal treatment to internal and cross-border users avoiding cross-subsidies. •Formalization and illustration of the approach. •Real data tests for the European interconnected systems should be performed

    The National Energy Board was requested by the Minister of Energy, Mines and Resources to identify possible measures to improve cooperation among Canadian electrical utilities and to enhance access for buyers and sellers of electricity to available transmission capacity through intervening systems for wheeling purposes. To identify measures to improve cooperation, a questionnaire was sent to electric utilities and other interested parties on the present extent and future possibilities for inter-utility cooperation. The questionnaire and its results are presented. It was found that there already exists a significant amount of inter-utility cooperation in Canada. Such cooperation generally involves interchanges of economy energy, non-economic capacity and energy, coordinated operation, resource sharing, maintenance scheduling, emergency supports, etc. There is a very limited degree of integrated generation expansion planning. Typically, these agreements are carried out under interconnection agreements negotiated on a bi-lateral basis. The highest current degree of cooperation exists under the auspices of the Alberta interconnected power system pool. Wheeling is limited and generally restricted to cases where the sender and receiver are the same entity or where power is wheeled to a utility purchasing it from the wheeler's system. 2 figs., 3 tabs

    2014-09-01

    Full Text Available La orientación emprendedora ha sido uno de los aspectos que mayor interés ha suscitado en los últimos años en el campo del entrepreneurship. La revisión de la literatura nos permite señalar la necesidad de abordar la ambigüedad y la complejidad de la relación entre la orientación emprendedora y los resultados empresariales. En este trabajo planteamos esta relación desde un enfoque configuracional, abordando la coherencia de factores relacionales —capital social— y organizativos —capacidades tecnológicas y de marketing— con la orientación emprendedora. El objetivo del trabajo consiste en desarrollar un modelo configuracional que explique el efecto moderador conjunto del capital social y las capacidades empresariales sobre la efectividad de la orientación emprendedora. Se establecen 3 modelos teóricos —universal, contingente y configuracional— que se definen mediante proposiciones teóricas. Exploramos y ejemplificamos empíricamente las relaciones establecidas mediante un estudio de casos de empresas agroalimentarias españolas. Finalmente, extraemos diversas conclusiones a partir de los modelos planteados y proponemos futuras líneas de investigación.

  19. Recubrimientos de TiN depositados mediante ACPVD sobre aleaciones de magnesio AM60

    Pichel, M.

    2013-06-01

    Full Text Available Magnesium alloys are reaching special interest due to their good specific properties, low cost and good manufacturing properties. However, their low hardness, wear and corrosion resistance limit their applications in certain sectors of industry. These drawbacks can be solved by applying hard ceramic coatings, such as nitrides or metal carbides. TiN is one of the most used coatings due to its high adhesion, hardness, low coefficient of friction and chemical stability. Physical vapor deposition by cathodic arc CAPVD, is a versatile technique, which uses low temperatures and high ionization energies, generating homogeneous coatings. To achieve coatings with high quality, a careful control of the manufacturing parameters is required, such as bias voltage, gas flow or intensity. This paper focuses on magnesium alloys, AM60, coated with TiN using physical vapor deposition cathodic arc technique (CAPVD at different intensity values (40A and 100A and surface preparation (grinding up to 4000 grit and polished to 3μm. It was included a final condition with an intermediate Al film. The samples were characterized by X-ray diffraction, roughness, optical microscopy and scanning electron.Las aleaciones de magnesio están alcanzando especial interés gracias a sus buenas propiedades específicas, bajo coste y buenas propiedades de moldeabilidad. No obstante su baja dureza, resistencia a desgaste y corrosión, limita sus aplicaciones en ciertos campos de la industria. Estos inconvenientes se pueden solucionar aplicando recubrimientos duros cerámicos, como nitruros o carburos metálicos. El TiN es uno de los más utilizados debido a su alta adherencia, dureza, bajo coeficiente de fricción y estabilidad química. La deposición física en fase vapor mediante arco catódico, ACPVD, es una técnica muy versátil, que emplea bajas temperaturas y altas energías de ionización, generando recubrimientos de bajo espesor, homogéneos y de calidad.

    Full Text Available El estudio partiendo de las más modernas corrientes doctrinales plantea cuál deba ser la relación entre el Derecho (administrativo y el resto de ciencias sociales. Partiendo de la existencia de una tradición fuertemente influenciada por puntos de vista jurídicos formalistas y, simultáneamente, del menosprecio a lo jurídico que puede percibirse tanto en la gestión pública cotidiana como en importantes perspectivas desde la ciencia política y otras ciencias sociales, el trabajo aborda la necesaria renovación epistemológica y metodológica de la doctrina administrativista, que aborde de modo distinto la clave de la actividad pública, el ejercicio de discrecionalidad, no concibiendo el papel de lo jurídico como un instrumento de control puramente negativo, sino también como una herramienta de orientación de ese ejercicio en pos de la buena administración y el buen gobierno en interacción, que no disolución, con otras ciencias sociales, de las cuales se distingue el Derecho, en definitiva, por tener los tribunales de justicia la última palabra sobre los conflictos que puedan generarse. The study deals with the relation between Law (administrative law and the rest of social sciences. On one hand, the study underlines the existence of a legal tradition strongly influences by formalistic approaches. On the other hand, , simultaneously, there is a lack of conscience of the importance of legal inputs in the daily public management as well as in relevant points of view from the academy in the area of political science and other social sciences. The work emphasizes the necessary epistemological and methodological renewal of the legal jurisprudence which should look at the key of the public activity in a distinct way: the use of discretionary powers. In that sense, the role of law not should be only an instrument of control purely negative but also a tool of orientation of this discretionary exercise looking for the good administration

    Full Text Available Throughout the history, the transportation of goods and related logistics have played an important role in human development and existence. This pertains to numerous interlinked processes, whose management is often linked to social system, international linkages, development of industry, market and market specifics. In modern times, the management of these processes is increasingly bound to globalization of production and market, moving of production to countries with cheaper labour force, environmental protection. The present Slovenian economy depends to a large extent on economies and corporate relations of the European Union and the world. Such inter-connectedness demands frequent transportation of semi-finished and finished goods. By providing timely delivery of goods, transportation consequently enables inter-organizational linkages and individual production, economic, market and other processes. Organizational and inter-organizational management of transport logistics demands profound understanding of transport flows, freight forwarding expertise and knowledge of transport, tax, environmental and other related regulations. Adequate knowledge and mastering of cultural, linguistic, national and other differences is important as well. The presented analysis and evaluation form the basis of the construction of inter-organizational model of logistics management in Slovenia.

    Full Text Available It has almost passed one century from the emergence of the idea of the inter-religious dialog. The idea, being based on the assumption that no religion has the absolute truth, believes that there is the possibility of the dialog between all the existent religions in the social world. The dialog could make the coexistence and peace between the religions possible. The importance of this issue is increasingly growing and different ideas have been presented in the different religion departments worldwide. After the Iranian Islamic Revolution, a new image of Islam was offered to the world. An image whose true exposure made the use of the inter-religious dialog unavoidable. This also caused appearance of different views between the Muslim scholars. This article seeks to provide a presentation of three different approaches to the inter-religious dialog by exploring the works of three eminent scholars in the field; Mohaghegh Damad, Abolhassan Navab and Mohammad Masjed Jamei. These three approaches are:   · Inter-religious dialog as an interaction-oriented action    · Inter-religious dialog as a necessity-oriented action    · Inter-religious dialog as a backgroubd-oriented action    The necessity-oriented action is the approach taken by Mohaghegh Damad. He emphasizes on the acceptance of other religions. The active action referring to this acceptance is the foundation of this approach. This approach, accepting the developmental discourse in the meaning of inter-religious dialog, believes that this kind of dialog has been evolved from defensive and opposing to a new meaning. Hence, the inter-religious dialog in its new meaning possesses three conditions; the existence of common rights, emphasis on mutual respect and the effort for the two sides for religious exchange. This approach­ assumes that we must first establish a pattern from the current experiences of inter-religious dialogs in order to have an ideal cooperation and to fortify it. Then

Los modelos estructural y aerodinámico han sido desarrollados mediante este software, ampliamente utilizado en la simulación del comportamiento dinámico de vehículos.Sobre el modelo resultante se he desarrollado un algoritmo de control basado en la metodologia PVA con la finalidad de obtener un seguimiento de trayectoria mediante acciones de control suaves. Empleando la metodología convencional de control PVA no es posible estabilizar el vehículo en todos los rangos de posicionamiento lateral (y y longitudinal (x. En este artículo los autores muestran como esta limitación en el diseño de una estrategia de control PVA convencional es solventada con una modificación consistente en sustituir los parámetros constantes del PVA clásico por funciones dependientes del desplazamiento.El sistema de control es implementado para adecuarse a los requerimientos de las actuaciones y se diseña sobre la plataforma de simulación multidominio Simulink. Con la finalidad de obtener una importante mejora en la respuesta de posicionamiento, se im- plementa un generador de trayectorias continuas.Una vez que el modelo es desarrollado y el sistema de control implementado, los autores presentan el modelo matemático y los resultados de las simulaciones realizadas. Éstas validan el empleo tanto de la metodología de control PVA aplicada, como de la alimentación de trayectorias predefinidas, no sólo para la posición, sino también para la velocidad y aceleración.

    Full Text Available En la actualidad existen dos variantes principales de vacunas orales contra el cólera: una basada en células inactivadas de diferentes biotipos y serotipos y otra basada en la administración de cepas vivas genéticamente atenuadas. Una vacuna por subunidades pudiera ser una variante muy atractiva. Este trabajo describe la purificación parcial y caracterización preliminar de extractos de proteínas de membrana externa-lipopolisacárido (PME-LPS, obtenidos a partir de Vibrio cholerae O1, con el interés de seleccionar un proteoliposoma que posteriormente será estructurado en forma de cocleatos para su uso por vía oral en humanos. Las preparaciones fueron obtenidas a través del uso de diferentes detergentes. La cantidad de LPS en cada preparación fue estimada mediante la determinación de las unidades endotóxicas en el ensayo del Limulus (LAL. La composición de cada muestra fue evaluada mediante SDS-PAGE y Dot Blot. La inoculación intranasal (IN en ratones Balb/c se utilizó para la evaluación de la inmunogenicidad de las preparaciones, y la respuesta inmune fue determinada por ELISA y el título de anticuerpos vibriocidas. El tamaño molecular de la preparación con mejores resultados en inmunogenicidad se estimó mediante la cromatografía en Sephacryl S-1000. Se obtuvieron diferentes perfiles electroforéticos de acuerdo con el tipo de detergente utilizado. El LPS fue identificado en todas las preparaciones y aquella obtenida con el SDS al 15% mostró la más baja relación proteínas/LPS y los mejores resultados en los ensayos de inmunogenicidad. Adicionalmente se comprobó que su tamaño molecular es similar al observado en el proteoliposoma de VAMENGOC- BC. La preparación obtenida con el SDS al 15% constituye un proteoliposoma, con capacidad para estimular altos niveles de anticuerpos IgG anti-LPS y altos títulos de anticuerpos vibriocidas, luego de su administración por vía intranasal en ratones.

    Full Text Available Si bien es innegable el interés de los numerosos estudios que intentan determinar mediante encuestas el grado de severidad del acoso escolar y la victimización entre iguales en las escuelas, pocos de los estudios publicados se han llevado a cabo mediante selección de muestras representativas de ámbito nacional que permita generalizar las características de este fenómeno. Más excepcional todavía es que dichos estudios hayan tenido carácter longitudinal. En el año 1999 se realizó el primer estudio nacional sobre el acoso y la exclusión social en el ámbito de la enseñanza secundaria española (Defensor del Pueblo-UNICEF, 2000. Los resultados aportaron un retrato preciso de las diferentes formas de victimización padecidas, presenciadas o realizadas por los estudiantes, informando de su incidencia relativa entre chicos y chicas, a lo largo de los diferentes cursos y en función de la titularidad de los centros (públicos/privados. Siete años más tarde se ha llevado a cabo un segundo estudio con el mismo diseño e instrumentos a fin de determinar posibles cambios en la incidencia del acoso y la exclusión social en la enseñanza secundaria. Los resultados de la comparación apuntan a un decremento en el porcentaje de estudiantes que se reconocen víctimas o agresores de algunos tipos de acoso, mientras que permanecen inalterados los relativos a la exclusión social y a la difusión de rumores a espaldas de un tercero. Estos resultados se discuten en relación con los esfuerzos de mejora de las relaciones llevados a cabo por los centros educativos.

    Full Text Available Resumen: La domótica consiste en la aplicación de técnicas provenientes de la automática industrial al hogar con objeto de ofrecer servicios que aporten, entre otras cosas, confort, seguridad y eficiencia energética a los usuarios. Hasta el momento la penetración de dichas técnicas en los hogares ha sido reducida. Una de las razones fundamentales de esta lenta transposición de técnicas de control al hogar es la dificultad de integración entre los diferentes sistemas presentes en el hogar.

  15. Political Technologies in Strengthening Ethnopolitical (Inter-Ethnic and Inter-Confessional Dialogue

    Directory of Open Access Journals (Sweden)

    Gayduk Vadim Vitalyevich

    2015-12-01

    Full Text Available Situations with uncertain developments and results are more often taking place in the world of politics. In this regard, the role of actors who are interested in the implementation of plans for peaceful conflict resolution and non-violence is becoming more urgent. The modern world is replete with situations in which a decision should be made only by qualified intermediaries (mediators, whose purpose is to resolve the conflict by the most effective and painless method. This article discusses the main aspects of the technology which is new for the political reality – political mediation as a vital means for solving complex inter-ethnic and interconfessional problems. The author attempts to identify general and specific characteristics of the conflict field that are peculiar for both international and inter-ethnic contradictions arising in the process of multilateral relations of nations with each other and between ethnic groups in multi-ethnic space. At this, the attention is focused on the fact that the conflicts arise out of the contradictions between the interests of these social organisms. The article provides the system of argumentation of the thesis that the use of mediation technologies helps to achieve the combination of the parties’ autonomy and to guarantee a mutually beneficial result on a common ground. For this purpose the conflicting parties endow a third party with certain powers – the mediator, who is involved in order to look at the conflict from the side and help conflicting actors to get rid of excessive emotion and bias in a dispute. Thus, political mediation is a form of alternative expert and political dispute resolution and settlement, voluntarily elected by conflicting communities on the basis of their desire to reach agreement and political objectivity.

  19. La televisión social en los países andinos. Análisis de los medios sociales en informativos y magazines

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Los países andinos transitan hacia la televisión digital al mismo tiempo en que se consolidan los medios sociales que otorgan a la audiencia la capacidad de interactuar en tiempo real, ello deriva en interrogantes como ¿existe integración de los medios sociales en la televisión?, ¿la audiencia participa en la definición de la televisión digital? y ¿estamos frente a la televisión social? La investigación pretende responder a las preguntas señaladas mediante el estudio de los programas de noticias y magazines de las estaciones de televisión líderes del área andina, en razón de que sus contenidos se emiten en tiempo real cuando se generaría el mayor interés de la audiencia. La metodología empleada es cuantitativa y cualitativa a partir del análisis de cuentas en Facebook y Twitter de las estaciones. Las hipótesis son que la televisión social gana aceptación en los países del área andina y que los canales de televisión no explotan los medios sociales. Se concluye que las estaciones privadas muestran más actividad que las públicas, que existe diferencia entre los informativos y el entretenimiento en seguidores y actividad en la red y que estamos en el inicio de la televisión social pero demanda más esfuerzos para integrar pantallas y medios sociales.

  1. Improving the Accuracy of Laplacian Estimation with Novel Variable Inter-Ring Distances Concentric Ring Electrodes

    Oleksandr Makeyev

    2016-06-01

    Full Text Available Noninvasive concentric ring electrodes are a promising alternative to conventional disc electrodes. Currently, the superiority of tripolar concentric ring electrodes over disc electrodes, in particular, in accuracy of Laplacian estimation, has been demonstrated in a range of applications. In our recent work, we have shown that accuracy of Laplacian estimation can be improved with multipolar concentric ring electrodes using a general approach to estimation of the Laplacian for an (n + 1-polar electrode with n rings using the (4n + 1-point method for n ≥ 2. This paper takes the next step toward further improving the Laplacian estimate by proposing novel variable inter-ring distances concentric ring electrodes. Derived using a modified (4n + 1-point method, linearly increasing and decreasing inter-ring distances tripolar (n = 2 and quadripolar (n = 3 electrode configurations are compared to their constant inter-ring distances counterparts. Finite element method modeling and analytic results are consistent and suggest that increasing inter-ring distances electrode configurations may decrease the truncation error resulting in more accurate Laplacian estimates compared to respective constant inter-ring distances configurations. For currently used tripolar electrode configuration, the truncation error may be decreased more than two-fold, while for the quadripolar configuration more than a six-fold decrease is expected.

    Adriana Edith Granero

    2014-06-01

    Full Text Available Lograr una arquitectura sustentable requiere, entre otros aspectos, incorporar consideraciones energéticas en etapas tempranas de los diseños arquitectónicos. Las definiciones ambientales involucran principalmente análisis numéricos y temporales, con un detalle de variables normalmente definidas en etapas avanzadas del trabajo proyectual, distantes de las resoluciones espaciales de la gestación inicial del diseño, especialmente durante el comienzo de la formación profesional. Se puede aplicar estos conocimientos técnicos en los alumnos, en etapas tempranas del proyecto, según las teorías de aprendizaje significativo y percepción, que sugieren capacidades de vinculación cognitiva, mediante tecnologías de información y simulaciones gráficas. Este artículo propone una secuencia de experiencias pedagógicas de integración, a partir de modelos para la resolución conjunta del diseño arquitectónico, que se enfoca en la elaboración de vistas espaciales graduadas según valores energéticos. Ello se ejemplifica con el dimensionamiento de vanos para iluminación natural en un recinto doméstico de trabajo, lo cual se relaciona con la privacidad y la visión exterior, como también con la comodidad y el consumo energético. El proceso se ensaya con grupos de estudiantes de arquitectura y a través de consultas con docentes y especialistas del área que reconocen una motivación significativa y de relación ambiental. Esta experiencia de integración gráfica implica una vinculación temprana de condiciones energéticas y espaciales, utilizable para la enseñanza y posterior desempeño profesional, que busca una arquitectura expresiva y ambientalmente responsable.

    Full Text Available Over the years, many organizations have involved in the implementation of inter-religious dialogue in Malaysia. However, there are stillthose who doubt the role and purpose of interreligious dialogue. This might be due to lack of information and understanding regardingthe methodology of dialogue and also about different types that it may take. The present study is aimed at exploring a few models ofinter-religious dialogue that have been practised by some organizations that actively involved in dialogue. The study focuses on a review of selected organizational or institutional dialoguemodels such as Center for Civilizational Dialogue (CCD, Students Representative Council of Malaysia Science University (HealthCampus and Inter-faith Spiritual Fellowship (INSaF. This study provides information concerning the various designs of inter-religiousdialogue model in Malaysia and proposes that different designs of inter-religious dialogue rely on its different types and goals. It is found that, the commonly practiced type of dialogue in Malaysia is educational type which focuses on exploring inter-religious commonalities as well as differences which consequently willincrease understanding and foster meaningful engagement between people of different ethnic and religious background in Malaysia. Thistype of dialogue is distinguished from conflict resolution types of dialogue which aims at identifying issues and generating action plansto conflicts or disputes.

    2007-01-01

    Traditionally, the literature on action research has been aimed at intra-organisational issues. These studies have distinguished between two researcher roles: The problem-solver and the observer. This article addresses the distinct challenges of action research in inter-organisational projects....... In addition to the problem-solver and observer roles, the researcher in an inter-organisational setting can serve as a legitimiser of the project and manage to involve partners that in an ordinary business-to-business setting would not have participated. Based on an action research project in a Danish inter......-organisational network, this article discusses potential pitfalls in the legitimiser role. Lack of clarity in defining the researcher role and project ownership in relation to the funding organisation and the rest of the network can jeopardise the project and potentially the credibility of the researchers.

  19. Fear or greed? Oxytocin regulates inter-individual conflict by enhancing fear in men.

    Science.gov (United States)

    Zheng, Huimin; Kendrick, Keith M; Yu, Rongjun

    2016-09-01

    People may choose non-cooperation in social dilemmas either out of fear (if others choose to defect) or out of greed (when others choose to cooperate). Previous studies have shown that exogenous oxytocin motivates a "tend and defend" pattern in inter-group conflict in which oxytocin stimulates in-group cooperation and out-group defense. Using a double-blind placebo-controlled design combined with a modified Prisoner's dilemma game (PDG), we examined the effect of oxytocin on social motivations in inter-individual conflict in men. Results showed that compared with the placebo group, oxytocin-exposed participants were less cooperative in general. Specifically, oxytocin amplified the effect of fear on defection but did not influence the effect of greed. Another non-social control study confirmed participants' decisions were sensitive to social factors. Our findings suggest that even when social group conflict is removed, oxytocin promotes distrust of strangers in "me and you" inter-individual conflict by elevating social fear in men.

    2016-01-01

    Inter-organisational communication failures during times of real-world disasters impede the collaborative response of agencies responsible for ensuring the public's health and safety. In the best of circumstances, communications across jurisdictional boundaries are ineffective. In times of crisis, when communities are grappling with the impact of a disaster, communications become critically important and more complex. Important factors for improving inter-organisational communications are critical thinking and problem-solving skills; inter-organisational relationships; as well as strategic, tactical and operational communications. Improving communication, critical thinking, problem-solving and decision-making requires a review of leadership skills. This discussion begins with an analysis of the existing disaster management research and moves to an examination of the importance of inter-organisational working relationships. Before a successful resolution of a disaster by multiple levels of first responders, the group of organisations must have a foundation of trust, collegiality, flexibility, expertise, openness, relational networking and effective communications. Leaders must also be prepared to improve leadership skills through continual development in each of these foundational areas.

    Full Text Available Objetivos. El Ministerio de Salud y Previsión Social de Bolivia convocó a principios de 2000 a varios expertos para que, a partir de la información disponible, elaboraran un método que permitiera identificar territorios críticos en un tema de por sí prioritario --la salud materna y neonatal-- y crear un mapa de la situación y de la capacidad instalada en las 112 provincias nacionales. En este estudio se describe el método utilizado. Métodos. Se crearon índices de la situación de salud y de la capacidad instalada. Los pasos seguidos en este proceso fueron los siguientes: 1 identificación de las variables incluidas en cada índice; 2 ponderación de las variables de cada índice; creación de una fórmula para cada índice; 4 elaboración de una planilla con los datos de cada provincia correspondientes a las variables elegidas y al valor porcentual provincial de cada índice, obtenido mediante la aplicación de la respectiva fórmula; 5 identificación de tres categorías continuas para cada índice, y 6 definición de la taxonomía. Resultados. De este modo, se obtuvo un mapa nacional de la situación de salud materna y de la capacidad instalada en cada una de las 112 provincias bolivianas, lo cual permitió seleccionar un número mínimo de provincias para realizar intervenciones conjuntas entre el Ministerio de Salud y Previsión Social y otras instituciones. Las 9 provincias seleccionadas tienen un total de 26 municipios que implican a 17 distritos sanitarios y concentran el 29% de la población del país, el 33% de las muertes maternas y el 35% de las defunciones neonatales tempranas estimadas. Conclusiones. Basándose en información disponible, el método utilizado proporcionó un mapa de la situación global, en este caso de la salud materna, de las 112 provincias de los 9 departamentos bolivianos que permite identificar territorios críticos para las intervenciones en materia de salud.

    This formal declaration commits the municipalities in the Greater Toronto Area, the provincial government of Ontario, and the federal government in Ottawa to undertake certain specific actions to improve air quality in their respective areas of jurisdiction, recognizing the validity of claims made by experts in numerous studies, linking air pollution to premature deaths, illnesses and hospitalization in major Canadian cities. The declaration also recognizes the validity of scientific claims as to the relationship between solar radiation, ambient heat, ground level ozone and global climate change, and the role played in air pollution by fossil fuel combustion. The Declaration calls for cooperation of all governments operating in the Greater Toronto Area to take inter-governmental actions to improve air quality by following up on key issues identified at annual Summits and by supporting the planning of future Summits, by working together with the Toronto Organizing Committee for the Olympic Games to ensure that the 2008 Olympic Games will contribute to a legacy of clean air for the Toronto region, and by implementing a social marketing campaign to help householders reduce both home energy use and vehicle kilometres travelled by 20 per cent. Beyond these inter-governmental commitments, special commitments of individual municipalities, and the provincial and federal governments also form part of the Declaration

    Full Text Available This paper begins with an introduction to the social and political attitudes associated with the process of recovery of historical memory, with the aim of presenting the objectives and some results of the “Names and Voices” research project which has been conducted in Galicia since 2005. The social inclination to forget the past, which was a characteristic of the transition to democracy, has slackened since the mid-1990s, although it is yet to be replaced by a new attitude. We trace the trend towards a new appraisal of an uncomfortable past in the literature and films of the last few decades, and seek to define the phases of recovery of the hidden memory of the vanquished between 1975 and the present. We examine the evolution of public policies regarding historical memory in Galicia and explain the current process of compilation of information in order to construct a history of the violence associated with the coup d’état in Galicia. We then present some relevant data from the sources consulted. The when, how and who of the victims enables us to put forward some hypotheses regarding the reasons for eliminating the political opposition upon which the Franco dictatorship was founded. The violence and above all the murders constituted a form of terror whose aim was to impose and guarantee the success of the military coup. However, the physical elimination of political rivals, their persecution and extermination, were a means of solving political conflict characteristic of the European fascist regimes of the period. | Este trabajo comienza con una aproximación a las actitudes sociales y políticas vinculadas al proceso de recuperación de la memoria histórica con objeto de presentar los objetivos y algunos resultados del proyecto de investigación «Nomes y Voces» desarrollado en Galicia desde 2005.

    The SEM Scanner is a medical device designed for use by healthcare providers as part of pressure ulcer prevention programs. The objective of this study was to evaluate the inter-rater and inter-device agreement and reliability of the SEM Scanner. Thirty-one (31) volunteers free of pressure ulcers or broken skin at the sternum, sacrum, and heels were assessed with the SEM Scanner. Each of three operators utilized each of three devices to collect readings from four anatomical sites (sternum, sacrum, left and right heels) on each subject for a total of 108 readings per subject collected over approximately 30 min. For each combination of operator-device-anatomical site, three SEM readings were collected. Inter-operator and inter-device agreement and reliability were estimated. Over the course of this study, more than 3000 SEM Scanner readings were collected. Agreement between operators was good with mean differences ranging from -0.01 to 0.11. Inter-operator and inter-device reliability exceeded 0.80 at all anatomical sites assessed. The results of this study demonstrate the high reliability and good agreement of the SEM Scanner across different operators and different devices. Given the limitations of current methods to prevent and detect pressure ulcers, the SEM Scanner shows promise as an objective, reliable tool for assessing the presence or absence of pressure-induced tissue damage such as pressure ulcers.

  18. Social information

    Directory of Open Access Journals (Sweden)

    Luiz Fernando de Barros Campos

    Full Text Available Based on Erving Goffman's work, the article aims to discuss a definition of information centered on the type conveyed by individuals in a multimodal way, encompassing language and body in situations of co-presence, where face-to-face interaction occurs, and influencing inter-subjective formation of the self. Six types of information are highlighted: material information, expressive information, ritualized information, meta-information, strategic information, and information displays. It is argued that the construction of this empirical object tends to dissolve the tension among material, cognitive and pragmatic aspects, constituting an example of the necessary integration among them. Some vulnerable characteristics of the theory are critically mentioned and it is suggested that the concept of information displays could provide a platform to approach the question of the interaction order in its relations with the institutional and social orders, and consequently, to reassess the scope of the notion of social information analyzed.

    VICbus is a standard inter-crate cable bus being developed by a working group of the ISO/IEC. Derived from an initiative of the VMEbus Working Group of ESONE, VICbus aims to provide users of multi-crate VMEbus and other backplane bus systems with a standard inter-crate connection. Multi-drop operation is provided for up to 31 devices on a cable of maximum 100 metres in length. Two data transfer protocols are specified, compelled (asynchronous) transfers for transparent interconnection of backplane bus systems (VMEbus in the first instance), and high-speed, non-compelled (synchronous) transfers between VICbus interfaces. A limited interrupt mechanism is specified, as well as simple, but efficient arbitration technique. Conventional technology is employed: copper cables, existing transcievers, and differential signal transmission, together with proven low-level protocols. Data transfer rates in excess of 30 Mbyte/s will be possible on a cable length of 30 metres

    Full Text Available The Atmospheric Correction Inter-comparison eXercise (ACIX is an international initiative with the aim to analyse the Surface Reflectance (SR products of various state-of-the-art atmospheric correction (AC processors. The Aerosol Optical Thickness (AOT and Water Vapour (WV are also examined in ACIX as additional outputs of AC processing. In this paper, the general ACIX framework is discussed; special mention is made of the motivation to initiate the experiment, the inter-comparison protocol, and the principal results. ACIX is free and open and every developer was welcome to participate. Eventually, 12 participants applied their approaches to various Landsat-8 and Sentinel-2 image datasets acquired over sites around the world. The current results diverge depending on the sensors, products, and sites, indicating their strengths and weaknesses. Indeed, this first implementation of processor inter-comparison was proven to be a good lesson for the developers to learn the advantages and limitations of their approaches. Various algorithm improvements are expected, if not already implemented, and the enhanced performances are yet to be assessed in future ACIX experiments.

  3. Inter-atomic interaction between electrons, 2

    Intra- and inter-atomic interactions in the exchange process are defined with respect to the Wannier function rather than the atomic function. In relation to the neutron scattering data for nickel, the behavior for the effective exchange parameter I(q) in the q-dependent susceptibility is, in RPA, investigated by taking into account the main types of the nearest neighbor interactions and by extending our previous treatment. The different types of interactions lead to different behavior for the q-dependence of I(q). The contribution to I(q) from inter-atomic interactions other than the exchange type decreases as the surface area of the Fermi surface becomes large. For the exchange type, the l-th neighbor interaction with l<=4 is taken into account, and, from the comparison with the empirical result for I(q), it is found that the inter-atomic contribution to I(0) is about thirty percent with a reasonable decrease against l.

  4. Inter-cellular transport of ran GTPase.

    Directory of Open Access Journals (Sweden)

    Deepak Khuperkar

    Full Text Available Ran, a member of the Ras-GTPase superfamily, has a well-established role in regulating the transport of macromolecules across the nuclear envelope (NE. Ran has also been implicated in mitosis, cell cycle progression, and NE formation. Over-expression of Ran is associated with various cancers, although the molecular mechanism underlying this phenomenon is unclear. Serendipitously, we found that Ran possesses the ability to move from cell-to-cell when transiently expressed in mammalian cells. Moreover, we show that the inter-cellular transport of Ran is GTP-dependent. Importantly, Ran displays a similar distribution pattern in the recipient cells as that in the donor cell and co-localizes with the Ran binding protein Nup358 (also called RanBP2. Interestingly, leptomycin B, an inhibitor of CRM1-mediated export, or siRNA mediated depletion of CRM1, significantly impaired the inter-cellular transport of Ran, suggesting a function for CRM1 in this process. These novel findings indicate a possible role for Ran beyond nucleo-cytoplasmic transport, with potential implications in inter-cellular communication and cancers.

  5. Inter-utility trade in electricity

    1992-01-01

    Enhanced inter-utility cooperation could have a profound effect on the future of the electricity supply industry. Coordinated planning, development, and operations of electric power systems have the potential to reduce the cost of electricity to consumers and to lessen the impact of electricity supply on the environment. These effects could be achieved by being able to supply electricity from lower cost and more environmentally benign sources located over wider geographic areas, and having to install less new generating capacity. Access to transmission and wheeling services would be an important factor in allowing increased inter-utility cooperation to occur. Canada's National Energy Board conducted a review to identify measures that can be taken to enhance interprovincial trade in electricity, to encourage greater cooperation between electric utilities in the areas of systems planning and development, and to enable buyers and sellers of electricity to obtain access to available transmission capacity through intervening provinces for wheeling purposes. The work undertaken by the Board during that review is described. A total estimated economic benefit of $23-32.5 billion was identified, mainly from long-term firm sales and from seasonal diversity exchanges. Four options were developed that appear to be available to encourage and achieve enhanced inter-utility cooperation. These are continuation of voluntary cooperation, voluntary cooperation with federal monitoring, establishing voluntary regional planning entities, and establishing regional planning entities with mandated federal power

    The free and open data access policy to Landsat-8 (L-8) and Sentinel-2 (S-2) satellite imagery has encouraged the development of atmospheric correction (AC) approaches for generating Bottom-of-Atmosphere (BOA) products. Several entities have started to generate (or plan to generate in the short term) BOA reflectance products at global scale for L-8 and S-2 missions. To this end, the European Space Agency (ESA) and National Aeronautics and Space Administration (NASA) have initiated an exercise on the inter-comparison of the available AC processors. The results of the exercise are expected to point out the strengths and weaknesses, as well as communalities and discrepancies of various AC processors, in order to suggest and define ways for their further improvement. In particular, 11 atmospheric processors from five different countries participate in ACIX with the aim to inter-compare their performance when applied to L-8 and S-2 data. All the processors should be operational without requiring parametrization when applied on different areas. A protocol describing in details the inter-comparison metrics and the test dataset based on the AERONET sites has been agreed unanimously during the 1st ACIX workshop in June 2016. In particular, a basic and an advanced run of each of the processor were requested in the frame of ACIX, with the aim to draw robust and reliable conclusions on the processors' performance. The protocol also describes the comparison metrics of the aerosol optical thickness and water vapour products of the processors with the corresponding AERONET measurements. Moreover, concerning the surface reflectances, the inter-comparison among the processors is defined, as well as the comparison with the MODIS surface reflectance and with a reference surface reflectance product. Such a reference product will be obtained using the AERONET characterization of the aerosol (size distribution and refractive indices) and an accurate radiative transfer code. The inter

When the insured apply with a petition, describing that s/he cannot work because of the diseases, retirement process begins. First Social Security Institution in case of objection Social Security Supreme Council of Health prepares reports about individuals. Third Specialization Board of the Council of Forensic Medicine is the final expertise authority on these cases. With this study it is aimed to reveal the decision differences on 'retirement due to disability1 cases between the Third Specialization Board of the Council of Forensic Medicine and the other institutions and, guided with the findings, to provide the standardization in practical implementation. Materials and Methods: For this study; the reports of the 3rd Specialization Board of The Council of Forensic Medicine were retrospectively investigated and the cases who were reported as not suitable for the retirement due to diseases by Social Security Institution and Social Security Supreme Council of Health but reported as suitable for the retirement due to diseases by the 3”1 Specialization Board were included. Results: Totally sixty four cases were determined. Fifty seven of the cases were male and seven ofthem were female. Average age of female cases was 50.71, male cases were 49.89 and average age of all cases was 49.98. Conclusion: Even the rules and regulations are same, there are differences between institutions. While rules and regulations are constituted, taking common decisions by negotiating on practice principles should reduce the differences between institutions and provide faster decision makings. Institutions should arrange routine meetings and discuss about the cases and present assessments interactively. Keywords: Working Power Loss, Inter-Instutional Comparison, Forensic medicine.

    Full Text Available Abstract Background The concept of frailty, a relative state of weakness reflecting multiple functional and health domains, continues to receive attention within the geriatrics field. It offers a summary of key personal characteristics, providing perspective on an individual’s life course. There have been multiple attempts to measure frailty, some focusing on physiologic losses, others on specific diseases, disabilities or health deficits. Recently, multidimensional approaches to measuring frailty have included cognition, mood and social components. The purpose of this project was to develop and evaluate a Home Care Frailty Scale and provide a grounded basis for assessing a person’s risk for decline that included functional and cognitive health, social deficits and troubling diagnostic and clinical conditions. Methods A secondary analysis design was used to develop the Home Care Frailty Scale. The data set consisted of client level home care data from service agencies around the world. The baseline sample included 967,865 assessments while the 6-month follow-up sample of persons still being served by the home care agencies consisted of 464,788 assessments. A pool of 70 candidate independent variables were screened for possible inclusion and 16 problem outcomes referencing accumulating declines and clinical complications served as the dependent variables. Multiple regression techniques were used to analyze the data. Results The resulting Home Care Frailty Scale consisted of a final set of 29 items. The items fall across 6 categories of function, movement, cognition and communication, social life, nutrition, and clinical symptoms. The prevalence of the items ranged from a high of 87% for persons requiring help with meal preparation to 3.7% for persons who have experienced a recent decline in the amount of food eaten. Conclusions The interRAI Home Care Frailty Scale is based on a strong conceptual foundation and in our analysis, performed as

    Full Text Available The interaction between immigrants and members of the host society has been and still is an important issue during processes of migration. This study analyses inter-ethnic aggressive antisocial actions among adolescents. A descriptive analysis reveals the frequency of such behaviour among German, Turkish and Resettler (Aussiedler adolescents. The explanatory analysis concentrates on the influence of a attitudes towards violence (justifications, b an approval with social dominance, c bargaining as a conflict resolution strategy, and d trust in the judicial system (a fair treatment according to the law. It is assumed that justifications for violent behaviour and the approval with social dominance are likely to increase inter-ethnic aggressive antisocial actions. In contrast, bargaining as a preference for conflict resolution and trust in the judicial system are supposed to reduce such behaviour. A final comparison reveals whether the explanations are substantial across the groups.

    Existing reliable ordered group communication protocols have been developed for local-area networks and do not, in general, scale well to large numbers of nodes and wide-area networks. The InterGroup suite of protocols is a scalable group communication system that introduces a novel approach to handling group membership, and supports a receiver-oriented selection of service. The protocols are intended for a wide-area network, with a large number of nodes, that has highly variable delays and a high message loss rate, such as the Internet. The levels of the message delivery service range from unreliable unordered to reliable group timestamp ordered.

    Full Text Available The articol presents a category of consumption models which shows the manner how theexpenses of consume in an economy are related to the available income achieved by this economy and theinterest rate from the financial market. Since the income as well as the expenses of consume are realizedin time, such dynamic models of consume are also referred to as models of inter-temporal consume,emphasizing therefore the fact that the available income achieved at a certain moment may be used forconsume at a future moment, whereas the decision of consume taken at a current moment may consider theincome that is to be achieved in the future.

    In the present paper, we analyse the role of demand factors on wages and hours in Switzerland. To accomplish this task, we used the 1996 Swiss Wage Structure Survey, a large employee-employer survey. Results indicate that capital intensity appears to have a certain impact on the relation between wages and hours: the "inter-industry wage-hours differentials line" we inferred is clearly positive. Further, an analysis of the determinants of inter-firm wage differentials shows that the internal o...

    We modify and simplify the inter-channel nonlinearity (NL) estimation method by using differential pilot. Compared to previous works, the inter-channel NL estimation method we propose has much lower complexity and does not need modification of the transmitter. The performance of inter-channel NL monitoring with different launch power is tested. For both QPSK and 16QAM systems with 9 channels, the estimation error of inter-channel NL is lower than 1 dB when the total launch power is bigger than 12 dBm after 1000 km optical transmission. At last, we compare our inter-channel NL estimation method with other methods.

Participants were 200 working adults who were studying part-time in a long-distance program in a university in Malaysia. In general, demographic factors (gender, ethnicity, education, and income had no significant relationships with number of inter-ethnic friends and satisfaction people had with inter-ethnic friendships. Ethnic identity and stress at work also did not have significant relationships with number of inter-ethnic friends. However, they were significantly related to satisfaction with inter-ethnic friendships. People with higher ethnic identification were more satisfied with inter-ethnic friendships whereas people with more stress at work reported lower satisfaction with inter-ethnic friendships.

    Full Text Available This article examines the interconnections between environmental issues and the protection of human rights, in a process that began in the United Nations Conference on the Human Environment (Stockholm, 1972 and has been developed by the greening of the regional human rights systems. In the Inter-American system the article 11 of the Additional Protocol to the American Convention on Economic, Social and Cultural Rights of 1988 — the Protocol of San Salvador — guarantees the right to a healthy environment. However the American Convention (on its arts. 3-25, 44-51 and 61-69 and its Additional Protocol (on its arts. 8, 13 and 19.6 only allow the submission of individual petitions to the Inter-American Commission and the possible acting of the Inter-American Court, in complaints containing alleged violations of civil and political rights, trade union rights and the right to education. Despite the lack of devices that are capable to ensure an effective protection to the right to a healthy environment, by itself, the Inter-American Court has demonstrated the greening of the human rights, which means, in other words, that it is quite possible to protect environmental issues by the demonstration of its interconnections with civil and political rights that are directly protected by the inter-American system. Therefore, it is necessary to understand the contributions of the jurisprudence of the Inter-American Court in the strengthening of the civil and political rights in cases related to environmental issues.

  7. Safety assessment of inter-channel / inter-system digital communications: A defensive measures approach

    International Nuclear Information System (INIS)

    Thuy, N. N. Q.

    2006-01-01

    Inappropriately designed inter-channel and inter-system digital communications could initiate common cause failure of multiple channels or multiple systems. Defensive measures were introduced in EPRI report TR-1002835 (Guideline for Performing Defense-in-Depth and Diversity Assessments for Digital Upgrades) to assess, on a deterministic basis, the susceptibility of digital systems architectures to common-cause failures. This paper suggests how this approach could be applied to assess inter-channel and inter-system digital communications from a safety standpoint. The first step of the approach is to systematically identify the so called 'influence factors' that one end of the data communication path can have on the other. Potential factors to be considered would typically include data values, data volumes and data rates. The second step of the approach is to characterize the ways possible failures of a given end of the communication path could affect these influence factors (e.g., incorrect data values, excessive data rates, time-outs, incorrect data volumes). The third step is to analyze the designed-in measures taken to guarantee independence of the other end. In addition to classical error detection and correction codes, typical defensive measures are one-way data communication, fixed-rate data communication, fixed-volume data communication, validation of data values.

    Full Text Available En las últimas décadas, ha habido un marcado interés por aumentar la temperatura y la presión de vapor en las plantas de generación de energía con el propósito de disminuir el consumo de combustibles. Así, se conseguiría reducir las emisiones de contaminantes tales como CO2 SO2 y NOx. Para lograr estas mejoras, se requiere por un lado desarrollar nuevosaceros ferríticos-martensíticos con contenidos de Cr entre 9-12% y por otro lado, mediante la ingeniería de superficies, mejorar la resistencia a la oxidación de los ya existentes. En el presente trabajo se obtuvieron recubrimientos de Al y de Al-Hf y evaluó el efecto de la adición del Hf al lecho sobre el crecimiento de los recubrimientos de Al. Previamente a la obtención de los recubrimientos, se realizó un estudio termodinámico mediante el programa Themocalc y, de acuerdo a los resultados obtenidos, se depositaron las capas de Al y Al-Hf a tres temperaturas diferentes en el rango de 500 a 600 °C. Los recubrimientos fueron caracterizados mediante DRX y MEB/EDAX. De acuerdo con los resultados obtenidos se determinó que para ambos casos las capas estaban fundamentalmente formadas por los compuestos intermetálicos Fe2Al5 y FeAl3.

    Full Text Available Inter-row cultivators have some shortcomings: design is complicated due to placing on each section of a 4-unit (parallelogram suspension of working tools; as the copying means use wheels which are mounted at distance from working tools, in other vertical plane, and have negative effect on variability of tillage depth; working tools are V-shaped hoes with a crumbling angle not more than 16 degrees. In the operation course the parts of a leg and a hoe, moving in the soil, raise it and throw to the side, creating not aligned surface grooves are formed, imposed moist soil. These processes are exacerbated by increasing the operating speed of the cultivator. The authors offered a resource-saving inter-row cultivator with a radial suspension of working tools. A flat plate spring was used as a beam. This simplifies the design, eliminates the horizontal oscillations of the working tools, provides a constant pressing them in the process. The working tool in the form of a flat lancet plowshares with a spiral fixed on the leg was designed. Operating width of a ploughshare is of 420 mm, thickness equals 4 (5 mm. The spiral with a diameter of 50 mm is made of a carbon spring wire with a diameter of 2-3 mm. One hoe is set instead of three-five tines on each section, that significantly reduces material consumption. A plough share with a spiral form the swinging-loosening element that provides creating a fine lumpy topsoil. The ploughshare performs the copying functions therefore the additional copying wheels are not required. Tests showed that the new working tool of a cultivator allows to operate qualitatively at a speed up to 14-18 km/h.

    Full Text Available Social and civic conflict inspired by the fundamental convictions of different religious groups seems to be rife all over the world, also in schools. One way of addressing this problem is to promote inter-religious dialogue. To establish the viability of this solution, the authors take several steps. They analyze the phenomenon “religion” and discover that it is constituted of several layers or levels that have to be accounted for in the proposed inter-religious dialogue in schools. After discussing the term “dialogue” they consider several approaches to religious diversity or plurality to find a suitable basis for the proposed inter-religious dialogue in schools. Based on these analyses, the authors argue that schools (teacher-educators and learners should be allowed to engage in inter-religious dialogue as part of their pedagogical and civic duty. This will ensure a better understanding of others and their religions, also at the deepest spiritual level. Such comprehension can contribute to the more peaceful co-existence of people in religiously pluralist societies.

    To determine inter-observer and inter-examination variability of manual attenuation measurements of the vertebrae in low-dose unenhanced chest computed tomography (CT). Three hundred and sixty-seven lung cancer screening trial participants who underwent baseline and repeat unenhanced low-dose CT after 3 months because of an indeterminate lung nodule were included. The CT attenuation value of the first lumbar vertebrae (L1) was measured in all CTs by one observer to obtain inter-examination reliability. Six observers performed measurements in 100 randomly selected CTs to determine agreement with limits of agreement and Bland-Altman plots and reliability with intraclass correlation coefficients (ICCs). Reclassification analyses were performed using a threshold of 110 HU to define osteoporosis. Inter-examination reliability was excellent with an ICC of 0.92 (p < 0.001). Inter-examination limits of agreement ranged from -26 to 28 HU with a mean difference of 1 ± 14 HU. Inter-observer reliability ICCs ranged from 0.70 to 0.91. Inter-examination variability led to 11.2 % reclassification of participants and inter-observer variability led to 22.1 % reclassification. Vertebral attenuation values can be manually quantified with good to excellent inter-examination and inter-observer reliability on unenhanced low-dose chest CT. This information is valuable for early detection of osteoporosis on low-dose chest CT. (orig.)

    2017-12-01

    Inter-professional practice (IPP), necessary in today's healthcare environment, should be guided and practiced through inter-professional education (IPE). Within the context of an effective IPE program, collaborative medical professionals must be cognizant of the demands of patients' integrated care, organize a collaborative inter-professional team, and achieve the objectives of patient-centered care. However, the many challenges of IPE include insufficient understanding of inter-professional care, occupational culture-related boundary issues, lack of a college education, and insufficient support from academic and medical institutions. This article suggests adopting effective strategies to promote inter-professional recognition, create a harmonious medical culture, eliminate barriers to education, and enhance support for academic and medical institutions. Inter-professional collaboration between academic and clinical institutions must provide resources and substantive professional training. Effectively implementing IPE and IPP is expected to elicit trust, respect, and efficient communication from team members.

    Joachim Brüb

    2014-11-01

    Full Text Available Starting from the notion that making individuals in-teract across ethnic lines seems to be a major difficulty (Amir,1976, this comparative field study offers two explanations for the differences in inter-ethnic contacts among German, Turkish and Aussiedler (Resettler adolescents. One assumption is based on Social Identity Theory research with its central proposition that in group affiliation is likely to trigger out-group rejection. Thus in group favouritism is expected to decrease the frequency of inter-ethnic encounters. The other assumption is built on acculturation research and argues that certain dispositions towards acculturation facilitate or inhibit inter-ethnic contacts considerably. A preference for interaction is supposed to function as a facilitating factor where as assimilation is likely to prevent inter-ethnic encounters.On the whole the findings of this field study corroborate the assumptionsfor in-group favouritism and acculturation preferences.Further, young men tend more often to approve of in-group favouritism which prohibits inter-ethnic contact, while in contrast, young women more often agree with notions of dissimilation orinteraction which facilitate encounters with out-group members.Finally, subgroup analyses point to the importance of religious affiliation sand their consequences for inter-ethnic contacts under certain conditions.

    The type II AAA+ protein p97 is involved in numerous cellular activities, including endoplasmic reticulum-associated degradation, transcription activation, membrane fusion and cell-cycle control. These activities are at least in part regulated by the ubiquitin system, in which p97 is thought to target ubiquitylated protein substrates within macromolecular complexes and assist in their extraction or disassembly. Although ATPase activity is essential for p97 function, little is known about how ATP binding or hydrolysis is coupled with p97 conformational changes and substrate remodelling. Here, we have used single-particle electron cryomicroscopy (cryo-EM) to study the effect of nucleotides on p97 conformation. We have identified conformational heterogeneity within the cryo-EM datasets from which we have resolved two major p97 conformations. A comparison of conformations reveals inter-ring rotations upon nucleotide binding and hydrolysis that may be linked to the remodelling of target protein complexes.

    We examine a scenario of social conflict that is manifest during an interaction between government servants providing a service and citizens who are legally entitled to the service, using evolutionary game-theory in structured populations characterized by an inter-dependent network. Bribe-demands by government servants during such transactions, called harassment bribes, constitute a widespread form of corruption in many countries. We investigate the effect of varying bribe demand made by corrupt officials and the cost of complaining incurred by harassed citizens, on the proliferation of corrupt strategies in the population. We also examine how the connectivity of the various constituent networks affects the spread of corrupt officials in the population. We find that incidents of bribery can be considerably reduced in a network-structured populations compared to mixed populations. Interestingly, we also find that an optimal range for the connectivity of nodes in the citizen's network (signifying the degree of influence a citizen has in affecting the strategy of other citizens in the network) as well as the interaction network aids in the fixation of honest officers. Our results reveal the important role of network structure and connectivity in asymmetric games.

    Full Text Available The evolution of organizations that work in multinational environments has considerably altered their production strategies. One of the consequences has been the appearance of Horizontal Inter-firm Collaborations (HICs, which include all kinds of enterprises and production centres and establish a new type of horizontal collaborations and relations between independent companies or even competitors who establish occasional collaborations on projects they could not take on individually. HICs are dynamically changing organizations formed by Original Equipment Manufacturers (OEMs, Contract Manufacturers (CMs, turn-key and component suppliers, R+D centres and distributors. The dynamic relations that exist within the HICs allow them a very permeable organization easy to connect and disconnect from one to each other as well as to choose a set of partners with specific attributes. The result is a highly flexible system characterized by low barriers to entry and exit, geographic flexibility, low costs, rapid technological diffusion, high diversification through contract manufacturers and exceptional economies of scale. This study of organizational culture at the network level includes aspects such as cultural similarity among its actors, social embeddedness, tacit knowledge transfer or the importance of trust atinter-firm collaborations. The presence, under a systemic perspective, of homogeneous cultural values and practices in which collaboration actors can be identified may strengthen the group membership or establish a social network that underlies the own HIC and facilitates interactions among its members. The feasibility of this approach would facilitate the formation of new HICsby establishing, ex ante, a cultural prescriptive model at the network level. Finally, to validate the proposed model, the case methodology have been applied to an example within the aeronautical industry that has been one of the most successful relationships within HICs, the

  10. An Inter-Disciplinary Language for Inter-Disciplinary Communication: Academic Globalization, Ethos, Pathos, and Logos

    Full Text Available Inspired by the intersection of character, emotions, and logic, much like a Hungarian Rhapsody which is beautifully sad; this paper explores ethos, pathos, and logos in the context of Academic Globalization. As students of the world, an inter-disciplinary language is pivotal for inter-disciplinary communication. Given that the current state of the world stems primarily from miscommunications, it is imperative to launch a cognitive language tool which underscores global commonalities and mitigates cultural differences. Such a platform would foster interdisciplinary research, education, and communication. New paradigms would evolve, grounded in ethos, pathos, and logos. Like yin and yang, these states are interrelated, interacting, and interchanging learning spheres. Just as day and night blend at some point; just as the Parthenon epitomized Greek thought, celebrated the birthplace of democracy, and for the first time, depicted everyday citizens in friezes- underscoring their impactful role- ethos, pathos, and logos represent cross-disciplinary communication devices which synergistically transform and ignite academic globalization. The Literature Review links the concepts of ethos, pathos, and logos with the seminal work Lewis and his LMR framework, which has given birth to Cultureactive and subsequently to ICE [InterCultural Edge]. http://www.fuqua.duke.edu/ciber/programs/we_organize/ice/ Accessed February 14, 2014

    Full Text Available El hecho novedoso de contemplar la responsabilidad social empresarial como parte de la estrategia corporativa de las empresas pone de manifiesto la importancia de que esta sea conocida por todos los grupos de interés. Dados los últimos pasos a nivel gubernamental sobre la transparencia, aspecto muy demandado por la sociedad, se considera necesario realizar una primera aproximación sobre el estudio de las empresas de transporte público urbano en este campo por el impacto que genera su actividad en términos PIB y en el desarrollo sostenible de las ciudades donde operan. El objetivo de este trabajo es observar si las empresas de transporte público urbano divulgan información sobre responsabilidad social empresarial. Para ello, se analizan las páginas web de las 17 empresas de transporte público urbano de titularidad pública mediante la utilización del análisis de contenidos. La investigación ha puesto de manifiesto que la información sobre responsabilidad social empresarial que ofrecen es escasa, siendo las acciones medioambientales las más contempladas. Considerándose que el nivel de implantación es bajo o nulo, dado que solo el 23,53% de las empresas contemplan de 14 a 27 ítems analizados.

  12. Cluster consensus in discrete-time networks of multiagents with inter-cluster nonidentical inputs.

    In this paper, cluster consensus of multiagent systems is studied via inter-cluster nonidentical inputs. Here, we consider general graph topologies, which might be time-varying. The cluster consensus is defined by two aspects: intracluster synchronization, the state at which differences between each pair of agents in the same cluster converge to zero, and inter-cluster separation, the state at which agents in different clusters are separated. For intra-cluster synchronization, the concepts and theories of consensus, including the spanning trees, scramblingness, infinite stochastic matrix product, and Hajnal inequality, are extended. As a result, it is proved that if the graph has cluster spanning trees and all vertices self-linked, then the static linear system can realize intra-cluster synchronization. For the time-varying coupling cases, it is proved that if there exists T > 0 such that the union graph across any T-length time interval has cluster spanning trees and all graphs has all vertices self-linked, then the time-varying linear system can also realize intra-cluster synchronization. Under the assumption of common inter-cluster influence, a sort of inter-cluster nonidentical inputs are utilized to realize inter-cluster separation, such that each agent in the same cluster receives the same inputs and agents in different clusters have different inputs. In addition, the boundedness of the infinite sum of the inputs can guarantee the boundedness of the trajectory. As an application, we employ a modified non-Bayesian social learning model to illustrate the effectiveness of our results.

    Full Text Available En los estudios históricos, la expresión “red social” es utilizada principalmente como un concepto metafórico que implica la interconexión de diferentes individuos. Si bien este enfoque permite abordar aspectos funcionales de las redes sociales, no permite analizarlas sistemáticamente desde un punto de vista estructural. Superando el uso metafórico del concepto de red social, se adopta en esta investigación la metodología del Análisis de Redes Sociales (ARS para estudiar las redes personales tejidas durante las dos últimas décadas del siglo XVIII por los agentes sociales detentores de mayor capital social en la parroquia eclesiástica Inmaculada Concepción de La Cañada, provincia de Maracaibo de la antigua Capitanía General de Venezuela, mediante vínculos de parentesco consanguíneo y vínculos derivados de las instituciones eclesiásticas del matrimonio y el bautismo. La utilización de la metodología del ARS permitió ilustrar un enfoque todavía muy poco utilizado en la investigación histórica, y profundizar en aspectos de interés relativos a la creación de vínculos personales, la distribución del capital social y las estrategias de reproducción social puestas en práctica por los habitantes de una comunidad rural de la América Hispana.

    Full Text Available INTRODUCCIÓN. Las orejas prominentes son una deformidad no poco frecuente, que se caracteriza en la mayoría de los casos por la ausencia o subdesarrollo del antihélix, combinado con una concha profunda y una marcada separación de la oreja respecto del cráneo. El objetivo de este trabajo fue evaluar el comportamiento posoperatorio de un grupo de pacientes operados mediante otoplastia, y medir el grado de satisfacción estética de cada paciente. MÉTODOS. El universo de trabajo estuvo constituido por 93 pacientes operados mediante otoplastia, según los pasos descritos por Psillakis y con alguna variante específica para cada caso, entre el 1994 y el 2004. Los pacientes fueron citados para seguimiento a las 72 h, a los 7 días para retirar la sutura, al mes, a los 6 meses, al año y a los 18 meses. RESULTADOS. Se constató que el número de complicaciones fue poco significativo y que la mayoría de ellas se debieron al incumplimiento de las medidas posoperatorias indicadas. Solo se presentaron 2 casos con recidivas y el 96,8 % de los pacientes estuvieron conformes con el resultado estético obtenido. CONCLUSIONES. Nuestros resultados en cuanto a complicaciones fueron similares y un tanto menores a los documentados por otros autores. Los pacientes y sus familiares quedaron muy complacidos con este tipo de tratamiento y confirmaron haber logrado mejorar su autoimagen, tras lo cual la incorporación a la sociedad es más plena, con una vida social y económica más productiva.INTRODUCTION.

    Full Text Available Crocodylus moreletii representa un emblema para los ecosistemas tropicales de México pero actualmente está amenazada por extinción. Sorprendentemente, hay una falta de información de su constitución genética, que debe ser evaluada para un manejo apropiado ex situ y para toma de decisiones en la liberación de cocodrilos a su hábitat natural. El objetivo del estudio fue caracterizar y comparar la variabilidad genética de cuatro grupos poblacionales de C. moreletii (dos silvestres y dos nacidas ex situ. Mediante PCR se amplificaron siete loci de microsatélites polimórficos, sin embargo se encontró déficit de heterocigotos en las poblaciones (promedio H O=0.02 mermado por la presencia de alelos nulos. El AMOVA indicó que la mayor proporción de variabilidad genética se encuentra dentro de las poblaciones y una limitada diferenciación genética entre poblaciones (promedio F ST =0.03, probablemente debida al alto índice de endogamia (promedio F IS=0.97. Al comparar la variabilidad genética inter e intra especies de cocodrilianos, encontramos que en C. moreletii está muy por debajo de los reportados. Se concluye que la limitada variabilidad genética de las poblaciones nacidas ex situ probablemente se debe al efecto fundador derivado de la estructura social de sus progenitores, y de las poblaciones silvestres, por el efecto cuello de botella, inferido por el limitado tamaño efectivo de población que presentó históricamente en su distribución natural.Genetic variability in captive populations of Crocodylus moreletii (Crocodylia: Crocodylidae using microsatellites markers.

La gluteoplastia mediante lipoinyección debe ser una cirugía segura que partiendo de una planificación adecuada, permita un aumento moderado enfatizando contornos y mejorando la forma natural de la región glútea. Debe permitir obtener resultados predecibles, duraderos y reproducibles, además de ser aplicable en una amplia variedad de pacientes. Presentamos un método de gluteoplastia de aumento sistematizada con lipoinyección que además de ser reproducible, permite obtener resultados consistentes, naturales y permanentes, distribuyendo estratégicamente volúmenes en cuadrantes. Pacientes y Método. Con mínima manipulación del lipoaspirado, infiltramos cantidades controladas en 9 cuadrantes en cada nalga. El cuadrante central representa la zona de máxima proyección y recibe la mitad del volumen. Denominamos zonas primarias a los 4 cuadrantes en los ejes X-Y, zonas que reciben el 40% del volumen infiltrado. Las zonas secundarias o menores corresponden a los cuadrantes situados entre los cuadrantes principales, y reciben el 10% del volumen total. Resultados. Entre 2008 y 2013 intervenimos a 75 pacientes para aumento y remodelación de glúteos con la técnica descrita, todas mujeres de 24 a 52 años. Las pacientes presentaron una convalecencia favorable y una satisfacción del 93%. Nueve pacientes presentaron seromas que se resolvieron mediante aspiración en consultorio. No se presentaron complicaciones mayores. Conclusiones. Presentamos un método de remodelación glútea mediante lipoinyección que, además de ofrecer excelentes resultados, predecibles, consistentes, naturales y permanentes, es lógico y reproducible.

    Full Text Available Headed studs are nowadays the standard steel-concrete connectors because of their competitive advantages. Firstly, they provide a high degree of safety thanks to semiautomatic electric arc welding. These welds are not suitable for typical non-destructive tests. The analytical study comprises several models. The first vibration modes have been obtained. The experimental research has developed first the measurement of the natural frequencies of 28 headed-studs in the sonic range. Then they have been tested by non-destructive and destructive tests. Finally theirs tests have been compared with their respective frequency measurements. A clear relationship between the measured frequencies and the lack of penetration of the welds has been established, that confirms the analytical prediction of this effect of the internal weld imperfections. Therefore, the feasibility of simple and absolutely non-destructive tests of welded studs by in site measurement of natural frequencies in the sonic range has been clearly established in this work.

    Los pernos conectores aportan múltiples ventajas de uso, entre las que se encuentra el elevado margen de seguridad que ofrecen sus soldaduras ejecutadas mediante arco eléctrico. Estas soldaduras, aunque ampliamente fiables, son difícilmente comprobadas mediante ensayos no destructivos. El presente estudio plantea la inspección de soldaduras de pernos conectores mediante su espectro acústico. Analíticamente, la investigación se ha centrado en el cálculo de los primeros modos propios de vibración. Experimentalmente se han medido las frecuencias propias de resonancia de 28 pernos, en los que posteriormente se han llevado a cabo ensayos tanto no destructivos como destructivos. Se ha obtenido, tanto teórica como experimentalmente, una relación entre la frecuencia de vibración de los pernos conectores y la calidad de la soldadura. Por ello se verifica la posibilidad de inspección de estas

While estimated as being relatively low contributors to core damage frequency, ISLOCAs have been identified as major contributors to risk at nuclear power plants (NPPs). They have the potential to result in core melt and containment bypass, which may lead to the early release of large quantities of fission products. Recent events at several operating reactors have been identified as ISLOCA precursors. The occurrence of these events have raised concerns that the frequency of ISLOCA sequences might be underestimated in current state-of-the-art PRAs. In order to expand the current state-of-the-art, a Nuclear Regulatory Commission research program is being conducted by ED and G Idaho, Inc. at the Idaho National Engineering Laboratory. The objective of the ISLOCA research program is to generate qualitative and quantitative information on the hardware, human factors, and accident consequence issues that dominate nuclear power plant risks for ISLOCA. To meet this objective, the approach being taken includes analysis of all interfaces between the primary reactor coolant system and other, lower pressure systems. This historical experience (primarily, licensee event reports) has provided the basis for determining the scope of the analysis with respect to potential failure mechanisms of the pressure isolation boundary. It is important to note that in the vast majority of these events, the dominant failure was a human error. Because of their significance, human errors are given particular attention in the present analysis

    2011-01-01

    Full Text Available Este artículo propone una guía de lectura para el estudio de la RSE mediante tres dimensiones (herramienta de la actualidad, utilidad para la administración y construcción ideológica las cuales corresponden lógica e históricamente a la evolución de la RSE. En efecto, el estado de conocimiento y desarrollo de la RSE en las últimas dos décadas se cristaliza en un discurso y una serie de herramientas en la actualidad. El juego de útiles para su aplicación y evaluación constituye la dimensión de útil para la administración. Al discurso corresponde la dimensión ideológica y doctrinaria; de tal manera que éstas se entrelazan en la praxis de la administración. Estas dimensiones permiten comprender el contenido y la forma de la RSE. En otros términos, esta división teórica tridimensional es al propio tiempo una guía de lectura para el estudio de la RSE. Se concluye, que pese al progreso que la responsabilidad social empresarial representa, subsiste la contradicción entre su vocación humanista/ecologista frente al interés privado.

    Full Text Available La extracción de gas no convencional mediante fracturación hidráulica (fracking es una técnica controvertida, ya que a sus beneficios sociales y económicos se contraponen sus potenciales riesgos ambientales y sobre la salud humana. En el norte de la Región de Murcia, al igual que en otras zonas de España, se han concedido recientemente permisos de investigación y prospección para la posible explotación de yacimientos de gas mediante fracking, lo que ha originado la aparición de movimientos ciudadanos que abogan por su prohibición. El objetivo central de este trabajo es estudiar el conocimiento, la percepción y la aceptabilidad que tienen los ciudadanos de la Región de Murcia sobre la explotación de esta fuente de energía. Con este fin se realiza una encuesta en la que se implementa el método de la Valoración Contingente. Los resultados informan, entre otros, que algo más de dos tercios de la población estarían a favor de su implementación, condicionado a que salud y el medioambiente sean salvaguardados. A su vez cada familia murciana se muestra dispuesta a contribuir, en media, con 15 €/año como sobrecoste en el recibo eléctrico para fijar una moratoria en la explotación.

    Full Text Available La efectividad de la política monetaria bajo un esquema de metas de inflación como el propuesto por el Banco Central de Costa Rica se basa en buena medida en el correcto y oportuno pronóstico de la inflación a corto y mediano plazo con el fin de diseñar de mejor forma las acciones de política monetaria. Así, el propósito de este trabajo es desarrollar una herramienta complementaria para elaborar pronósticos de inflación mediante un enfoque bayesiano. Para lo anterior se propone la utilización de la metodología Bayesian Model Averaging y de Weighted Average Least Squares. Los modelos de proyección especificados permitirían ampliar y complementar el análisis que se realiza actualmente con el Modelo Macroeconómico de Proyección Trimestral (MMPT del Banco Central de Costa Rica. Como resultado esta investigación muestra que, para datos de periodicidad mensual y a horizontes de pronóstico de 1 a 12 meses, es posible encontrar proyecciones mediante un proceso bayesiano que poseen una mayor capacidad predictiva en relación con aquellas producidas por un modelo autorregresivo.

    2004-01-01

    Full Text Available En el presente artículo se expone el método de dimensionamiento de sistemas termosolares mediante el uso de un modelo matemático. Este método es comúnmente usado debido que es simple, flexible pero a la vez muy potente. La simulación del sistema termosolar se realiza en base a un modelo matemático que describe los fenómenos térmicos que ocurren mediante un conjunto de ecuaciones diferenciales. Los parámetros que determinan el modelo son coeficientes de intercambio de calor entre los elementos del sistema, parámetros que representan las características de los componentes del sistema termosolar y parámetros que representan las condiciones en las que trabajará el sistema. Estos parámetros se determinan en base a recomendaciones de bibliografía, observaciones, mediciones de campo y correlaciones adecuadas. El uso de un modelo para el dimensionamiento de un sistema termosolar resulta una herramienta muy útil, ya que se adapta a distintas configuraciones de sistemas termosolares. Permite asimismo, tener una idea bastante aproximada del comportamiento del sistema termosolar en distintas condiciones de uso, la que sólo podría obtenerse a través de experimentos físicos complicados y por ende costosos.

    Inter-Noise (International Congress on Noise Control Engineering) is a society on noise/vibration and the control technology. Inter-Noise 99 was held on December 6, 7 and 8, 1999, at Fort Lauderdale, Florida, the U.S. The theme was Noise Control in the New Millennium. The number of the participants registered was 555 (151 from the U.S., 89 from Japan, 248 from European countries, and 69 from Asian/other countries). Dr. Harold Marshall gave a keynote lecture titled Noise Control by Design in the 21st Century - An Architectural Acoustic Perspective. From a standpoint of architectural acoustics, he stated the perspective, subjects, and course of the technical development pertaining to technologies needed in the 21st century. The papers read are mostly from the following fields: measuring technology, military exercise noise, modeling, forecast and simulation, aerodynamic/underwater sound, etc. In the session on the tire noise where the author read a paper, 14 papers were read. The number of the papers read was more than that in 1998, probably influenced by the tire noise regulation in Europe and Japan. (translated by NEDO)

  17. Malaria in inter-war British India.

    Bynum, W F

    2000-06-01

    British India was an important site of much important malaria research. Although Ronald Ross left India in 1899, a number of malariologists continued the task of evaluating the incidence and distribution of malaria in the country. Implementing practical solutions was hampered by formidable social and economic problems. This paper examines the Indian situation in the late 1920s, through a retrospective selection of writings chosen by J.A. Sinton for reproduction in an early issue of 'The records of the malaria survey of India', and the analysis of the Indian malaria situation through a visit of the League of Nations Malaria Commission in 1929.

  18. Replacement of harmful animal use in life science education: the approach and activities of InterNICHE.

    2004-06-01

    Harmful animal use in undergraduate education is increasingly being replaced by alternatives, such as computer software, manikins and simulators, ethically sourced animal cadavers, apprentice work with animal patients, and student self-experimentation. Combinations of such alternatives can better meet teaching objectives, reduce costs and avoid the negative pedagogical and social impact of animal experimentation. Since 1988, the International Network for Humane Education (InterNICHE, formerly EuroNICHE) has been working with teachers to replace harmful animal use and has been supporting students' right to conscientious objection. This paper presents the approach, history and current activities of InterNICHE. With a vision of 100% replacement, the network aims for empowerment by networking information and providing support. It works with the belief that most teachers want investment in the best quality and most humane education possible. The forthcoming second edition of the InterNICHE book, from Guinea Pig to Computer Mouse,1 includes practical details of progressive teaching aids and approaches, as well as case studies from teachers who employ such alternatives. In 1999, InterNICHE produced the film Alternatives in Education, now available in 20 languages. Such resources are complemented by outreach trips and conferences and an Alternatives Loan System, which offers products for familiarisation and assessment. The InterNICHE website (www.interniche.org) was launched in 2001.

    2014-10-20

    This report investigates for the first time the potential inter-treatment bias source of cell number for gene expression studies. Cell-number bias can affect gene expression analysis when comparing samples with unequal total cellular RNA content or with different RNA extraction efficiencies. For maximal reliability of analysis, therefore, comparisons should be performed at the cellular level. This could be accomplished using an appropriate correction method that can detect and remove the inter-treatment bias for cell-number. Based on inter-treatment variations of reference genes, we introduce an analytical approach to examine the suitability of correction methods by considering the inter-treatment bias as well as the inter-replicate variance, which allows use of the best correction method with minimum residual bias. Analyses of RNA sequencing and microarray data showed that the efficiencies of correction methods are influenced by the inter-treatment bias as well as the inter-replicate variance. Therefore, we recommend inspecting both of the bias sources in order to apply the most efficient correction method. As an alternative correction strategy, sequential application of different correction approaches is also advised. Copyright © 2014 Elsevier B.V. All rights reserved.

    facilities needed for next generation of underground assessments and experiments. There are growing interests in developing multi-disciplinary programs in DULs and some URLs have rooms set aside for physics experiments. Examples of DULs and URLs with interactions between earth sciences and physics include Gran Sasso in Italy, Kaimioka in Japan, Canfranc in Spain, LSBB in France, WIPP in New Mexico, DUSEL in South Dakota, and Jing Ping deep tunnel underground laboratory proposal in China. Instruments of common interests include interferometers, laser strain meters, seismic networks, tiltmeters, gravimeters, magnetometers, and other sensors to detect signals over different frequencies and water chemical analyses, including radon concentrations. Radon emissions are of concern for physics experiments and are studied as possible precursors of earthquakes. Measuring geoneutrino flux and energy spectrum in different locations is of interests to both physics and earth sciences. The contributions of U and Th in the crust and the mantle to the energy production in the Earth can be studied. One final note is that our ongoing reviews are aimed to contribute to technological innovations anticipated through inter-disciplinary interactions.

    Inter- and intragranular currents, J c inter and J c intra , in LaFePO 0.94 F 0.06 polycrystalline sample are evaluated by measuring the remanent-state field profile using magneto-optical imaging method. Obtained images show the absence of magnetic field modulation associated with the weak-link nature of grain boundaries, indicating that J c inter and J c intra are comparable in magnitude in contrast to other iron-arsenide superconductors. J c inter is estimated to be 2 x 10 4 A/cm 2 in the limit of T = 0 K, which is larger than the values in other iron-arsenide superconductors. Implication of these J c behavior is discussed in relation with possible pairing symmetries.

    2012-01-01

    Full Text Available The article deals with an investigation of the relationship between inter-organizational trust and performance. Using data obtained in a questionnaire survey in 373 organizations with more than 20 employees with their seat in the Czech Republic, we found the relationship between inter-organizational trust and supplier performance, mediated by the level of conflict. Also, the statistically significant negative relationship between inter-organizational trust and costs of negotiation and the statistically significant positive relationship between supplier performance and perceived performance were confirmed.

    Full Text Available This paper presents the development of the inter-communal relations in Lebanon and it approaches issues such as diversity and identity. Ever since the creation of modern Lebanon in 1920, the principle of proportionality has been subject of a significant inter-communal debate. Although, proportionality was to support state’s development and fair representation of all religious groups, it ended up the basis for a rigid political system, which turned into a major problem for the inter-communal political relationship, situation which escalated to civil war. The war, not only emphasized the inter-communal debate of what constituted a fair power-distribution system, but it also deepened this question, because it added new components such as new political actors.

    We derive general and explicit expressions for the unrenormalized and renormalized dressed propagators of fermions in parity-nonconserving theories with inter-generation mixing. The mass eigenvalues, the corresponding mass counterterms, and the effect of inter-generation mixing on their determination are discussed. Invoking the Aoki-Hioki-Kawabe-Konuma-Muta renormalization conditions and employing a number of very useful relations from Matrix Algebra, we show explicitly that the renormalized dressed propagators satisfy important physical properties.

    If inter-bunch wake fields are flat, i.e. their variations over a bunch length can be neglected, all coherent modes have the same coupled-bunch structure, provided the bunches can be treated as identical by their inner qualities (train theorem). If a flat feedback is strong enough, the transverse modes are single-bunch, provided the inter-bunch wakes are also flat (damper theorem).

    Functional near-infrared spectroscopy (fNIRS) is an increasingly popular technology for studying social cognition. In particular, fNIRS permits simultaneous measurement of hemodynamic activity in two or more individuals interacting in a naturalistic setting. Here, we used fNIRS hyperscanning to study social cognition and communication in human dyads engaged in cooperative and obstructive interaction while they played the game of Jenga™. Novel methods were developed to identify synchronized channels for each dyad and a structural node-based spatial registration approach was utilized for inter-dyad analyses. Strong inter-brain neural synchrony (INS) was observed in the posterior region of the right middle and superior frontal gyrus, in particular Brodmann area 8 (BA8), during cooperative and obstructive interaction. This synchrony was not observed during the parallel game play condition and the dialog section, suggesting that BA8 was involved in goal-oriented social interaction such as complex interactive movements and social decision-making. INS was also observed in the dorsomedial prefrontal cortex (dmPFC), in particular Brodmann 9, during cooperative interaction only. These additional findings suggest that BA9 may be particularly engaged when theory-of-mind (ToM) is required for cooperative social interaction. The new methods described here have the potential to significantly extend fNIRS applications to social cognitive research.

  17. Medida de la dureza de sólidos mediante nanoindentación

    Directory of Open Access Journals (Sweden)

    Alkorta, J.

    2005-10-01

    Full Text Available Hardness is not readily measurable by means of instrumented indentation since the value of the contact area depends on the pile-up or sink-in occurring near the contact surface of the sample. The most widespread method to estimate it by means of the loading/unloading curve of indentation, Oliver and Pharr’s method, deviates, in the extreme cases, up to a 25% from the real values since it only takes into account the elastic deflection. In this work, a new correction based on Oliver and Pharr’s method is proposed that agrees with the numerical calculations. Plastic hardening behaviour of the sample must be known to accurately estimate the contact area.

    La medida de la dureza mediante indentación con registro de carga y desplazamiento no es evidente, dada la incertidumbre sobre el tamaño de huella debido al levantamiento (pile-up o hundimiento (sink-in plásticos de la superficie de la muestra alrededor del indentador. El método más utilizado para la medida de la dureza mediante la curva de carga/descarga de indentación, el de Oliver y Pharr, sólo tiene en cuenta hundimiento elástico, por lo que el error en la medida de la dureza y el módulo de Young puede llegar hasta un 25% en los casos más extremos. En el presente trabajo se discute una posible corrección al método de Oliver y Pharr para una obtención más ajustada del área de contacto de la huella. Esta corrección requiere de un conocimiento a priori o a posteriori del comportamiento plástico del material.

  18. Impacts of inter- and intra- ethnic partnerships/relationships on traditional gift giving in a cohort of Pacific mothers.

    Traditional gift-giving (TGG) is an important element of familial obligations among Pacific families. Migration from Pacific homelands to New Zealand and other countries has had an impact on participation in TGG., Many anecdotal accounts have suggested that TGG diminishes when Pacific persons marry outside their ethnic groups. While TGG is an indicator of social cohesion TGG can have direct influence on disposable income. The practice of TGG impacts on health as Income and social cohesion are key determinants of health. Thus TGG Health and social cohesion are closely interrelated and interdependent. The data for this paper is taken from a longitudinal cohort study of 1,398 Pacific children and their families in South Auckland, New Zealand. The study sought participants' responses to questions pertaining to the amounts gifted, the frequency of giving, recipients of the gifting and their reasons for participating and not participating in TGG. The assumption explored in this paper is that as Pacific peoples move outside their social sphere and become more acculturated with other ethnic groups, TGG was more likely to diminish rather than increase. This paper addresses the TGG participation rates among Pacific peoples in inter-ethnic relationships and intra-ethnic relationships. It argues that couples in an intra-ethnic intimate relationship are more likely to participate in traditional gift-giving than those who are in inter-ethnic intimate relationships. While this is true for most PI inter ethnic relationships the level of participation increases further with inter-ethnic intimate relationships among Tongans and Samoans who are also the largest participators of all ethnic groups in traditional gift-giving.

    Full Text Available Si bien vivimos en una sociedad global, los educadores se enfrentan a numerosos desafíos a la hora de hallar formas significativas de conectar a los alumnos con gente de otras culturas. Este artículo muestra un caso práctico de colaboración entre profesores de los Estados Unidos y Turquía, en el que alumnos de séptimo grado interactuaron entre sí a través de las redes sociales con el fin de promover la comprensión cultural. Al analizar una única actividad de aprendizaje hallamos que los alumnos tenían la oportunidad de compartir ideas informalmente a través de las redes sociales, usando su voz digital para compartir significados mediante la escritura online, publicación de imágenes e hipervínculos. Este estudio halló que los alumnos valoraban la oportunidad de relacionarse entre sí y tendían a compartir su interés común en películas de Hollywood, actores, famosos, videojuegos y programas de televisión. Sin embargo, no todos los profesores valoraban el uso de la cultura popular como medio para la búsqueda de puntos en común. En efecto, los profesores tenían perspectivas muy distintas sobre el valor de esta actividad. Mediante la comunicación informal en torno a la cultura popular en una actividad de conocimiento mutuo, los propios alumnos descubrieron que sus conocimientos en común tendían a estar centrados en los Estados Unidos, en tanto en cuanto los alumnos americanos no tenían acceso a la cultura popular turca. Sin embargo, la actividad de aprendizaje permitió a los propios alumnos reconocer las dinámicas de poder asimétrico que existen en la cultura mediática global.

La responsabilidad social universitaria como concepto se presenta mediante la articulación de la metodología de investigación acción participativa, en la cual el proceso de análisis y propuesta de acciones a desarrollar son producto del diálogo y acuerdos entre actores de la academia y los sectores público y privado. Las conclusiones apuntan a que el desarrollo del ecoturismo, como necesidad identificada en el cambio de matriz productiva, requiere de una universidad que desde la interacción con grupos de interés sea catalizadora de los intereses de las diferentes partes y anteponga el trabajo participativo que garantice una visión conjunta en un área interdisciplinar como el turismo.

The concept of university social responsibility is introduced in the implementation of participatory action research, in which the process of analyzing and proposing actions to develop, derive from dialogue and agreements between academic actors, and both public and private sectors. Conclusions suggest that developing eco-tourism, as a need identified for a shift in the productive matrix, requires a university to work, from its interaction with interest

  6. Large-Scale Processes Associated with Inter-Decadal and Inter-Annual Early Spring Rainfall Variability in Taiwan

    Directory of Open Access Journals (Sweden)

    Jau-Ming Chen

    2016-02-01

    Full Text Available Early spring (March - April rainfall in Taiwan exhibits evident and distinct inter-annual and inter-decadal variability. The inter-annual varibility has a positive correlation with the El Niño/Southern Oscillation while the inter-decadal variability features a phase change beginning in the late 1970s, coherent with the major phase change in the Pacific decadal oscillation. Rainfall variability in both timescales is regulated by large-scale processes showing consistent dynamic features. Rainfall increases are associated with positive sea surface temperature (SST anomalies in the tropical eastern Pacific and negative SST anomalies in the tropical central Pacific. An anomalous lower-level divergent center appears in the tropical central Pacific. Via a Rossby-wave-like response, an anomalous lower-level anticyclone appears to the southeast of Taiwan over the Philippine Sea-tropical western Pacific region, which is accompanied by an anomalous cyclone to the north-northeast of Taiwan. Both circulation anomalies induce anomalous southwesterly flows to enhance moisture flux from the South China Sea onto Taiwan, resulting in significant moisture convergence nearby Taiwan. With enhanced moisture supplied by anomalous southwesterly flows, significant rainfall increases occur in both inter-annual and inter-decadal timescales in early spring rainfall on Taiwan.

    2004-05-01

    Currently, psychosocial stressors' impacts on health are increasing. Among these stressors, this review focused on inter-human relationships. Since social supports could be protective against ill health, consequences contributing to psychosocial stressors are discussed here in relation to social supports for each stage of childhood, adulthood and elderly status.For childhood, parental divorce/isolation, and child abuse/neglect appeared to be determinants of healthy development at either the initial or later stages. According to prospective studies, such stressors, especially those occurring until around 3 years of age, were associated with later adverse life quality in adulthood. Therefore, nationwide preventive strategies were developed in each country to monitor protective social programs.For adulthood, job strain was focused on Karasek's job strain model, effort-reward imbalance, employment grade and working hours. These psychosocial stressors were shown to affect not only the physical health but also the mental health of working people. These days, since Karoshi and even suicide related to excessive workloads are taking a toll on workplace organization, stress-coping abilities such as a sense of coherence were introduced from the individual-social interaction aspect.For elderly status, retirement, caring for the elderly, and spouse bereavement were discussed as psychosocial stressors. Some evidence indicates that these stressors could be determiants of health. Finally, social supports have been demonstrated to promote health and protect the elderly against diseases and death.

    Full Text Available Después del sismo de 1999 en Armenia, el estudio del comportamiento estructural de los sistemas de bahareque en Colombia toma relevancia debido al buen comportamiento que éstos presentaron ante el evento sísmico. Los estudios buscaban la tecnifi- cación en la construcción de viviendas en bahareque y brindar los requisitos mínimos para obtener un grado adecuado de sis- morresistencia y evitar así el colapso; además si se tiene en cuenta que la guadua es un material económico y rentable, social y culturalmente aceptado en una amplia región del país, se estaría en presencia de un material alternativo y no convencional que con la identificación de sus limitaciones y un adecuado uso permitiría su implementación en la fabricación de viviendas econó- micas, funcionales y seguras. Lo anterior motivó la presente investigación, en donde se hizo una evaluación experimental de un sistema de pórtico en guadua escala 1:1 rigidizado mediante la adición de dos tipos de páneles prefabricados de bahareque y ensayado ante cargas horizontales. Se halló la capacidad de disipar energía del pórtico y el aporte a la rigidez al adicionar los páneles, obteniendo resultados bastante alentadores, en donde se redujeron derivas en aproximadamente un 50% y se aumentó la resistencia del sistema en más de un 40%. Paralelamente, se realizaron modelos matemáticos para comparar resultados ex- perimentales con resultados analíticos. Los modelos experimentales fueron construidos y ensayados en el Laboratorio de Mate- riales de la Facultad de Ingeniería de la Universidad Nacional de Colombia.

    Language and social skills are essential for intrapersonal and interpersonal functioning and quality of life. Since epilepsy impacts these important domains of individuals' functioning, understanding the psychosocial and biological factors involved in the relationship among epilepsy, language, and social skills has important theoretical and clinical implications. This review first describes the psychosocial and biological factors involved in the association between language and social behavior in children and in adults and their relevance for epilepsy. It reviews the findings of studies of social skills and the few studies conducted on the inter-relationship of language and social skills in pediatric and adult epilepsy. The paper concludes with suggested future research and clinical directions that will enhance early identification and treatment of epilepsy patients at risk for impaired language and social skills.

    Full Text Available The concept of inclusive businesses (IB with the base of the pyramid(BOP has been developed to describe and systematize a set of experiences thatemerged in the 2000s, aimed at generating social inclusion by creating associativeenterprises for poor people, incorporated into the value chain of businesses. The theoretical development and empirical research on this strategy for economic andsocial inclusion are still emerging. Nevertheless, the analysis of a wide range of ex-periences has permitted developing some useful conceptual tools for guidingtheoretical reflection, empirical research and strategic analysis of this type of busi-ness. This document aims to present some of these tools that have been designedbased on the study of IB cases in Uruguay.

    Full Text Available Heterostructures of Si1-xGex alloys on Si (100 have been achieved using two different excimer laser techniques. The first one, the Laser Induced Chemical Vapour Deposition (LCVD, was used in order to deposit germanium on Si (100 substrates via photolysis of GeH4 as precursor gas. The resulting films show a very homogeneous and amorphous structure as determined by HREM, XRD and Raman analysis. These deposited amorphous germanium films and a part of their underlaying Si (100 substrate were melted using the second technique, the Pulsed Laser Induced Epitaxy (PLIE, inducing an epitactic recrystallization of a Si-Ge alloy. The analysis of the obtained alloys by HREM, XRD, and XPS, reveals a strong dependence of the crystal quality and of the germanium concentration profile from the number of pulses.

    El creciente interés que suscita la búsqueda de nuevas técnicas para la obtención de materiales semiconductores, compatibles con la tecnología del silicio, ha llevado a desarrollar un sistema de depósito y postprocesado en alto vacío (HV de Si-Ge mediante técnicas asistidas por láser excímero. Se han obtenido películas amorfas de germanio mediante el depósito químico en fase vapor inducido por láser (LCVD, que posteriormente han sido recristalizadas con uso de la inducción de epitaxia por medio de láser pulsado (PLIE. Las películas depositadas sobre substratos de silicio fueron caracterizadas mediante XRD, HREM y Raman, revelándose que son amorfas con un alto grado de homogeneidad. Se ha estudiado la morfología y la estequiometría de las muestras por medio de XRD, HREM y XPS tras el tratamiento para inducir la cristalinidad de la aleación sobre el substrato de silicio, observándose la dependencia del grado de heteroepitaxia y variación de la composición en la aleación, con el número y la energía de los pulsos del láser.

    Quality of life (Qol) is an increasingly used outcome measure in dementia research. The QUALIDEM is a dementia-specific and proxy-rated Qol instrument. We aimed to determine the inter-rater and intra-rater reliability in residents with dementia in German nursing homes. The QUALIDEM consists of nine subscales that were applied to a sample of 108 people with mild to severe dementia and six consecutive subscales that were applied to a sample of 53 people with very severe dementia. The proxy raters were 49 registered nurses and nursing assistants. Inter-rater and intra-rater reliability scores were calculated on the subscale and item level. None of the QUALIDEM subscales showed strong inter-rater reliability based on the single-measure Intra-Class Correlation Coefficient (ICC) for absolute agreement ≥ 0.70. Based on the average-measure ICC for four raters, eight subscales for people with mild to severe dementia (care relationship, positive affect, negative affect, restless tense behavior, social relations, social isolation, feeling at home and having something to do) and five subscales for very severe dementia (care relationship, negative affect, restless tense behavior, social relations and social isolation) yielded a strong inter-rater agreement (ICC: 0.72-0.86). All of the QUALIDEM subscales, regardless of dementia severity, showed strong intra-rater agreement. The ICC values ranged between 0.70 and 0.79 for people with mild to severe dementia and between 0.75 and 0.87 for people with very severe dementia. This study demonstrated insufficient inter-rater reliability and sufficient intra-rater reliability for all subscales of both versions of the German QUALIDEM. The degree of inter-rater reliability can be improved by collaborative Qol rating by more than one nurse. The development of a measurement manual with accurate item definitions and a standardized education program for proxy raters is recommended.

    In order to understand inter-particle as well as interfacial interaction of magnetic nanoparticles, we have prepared several Fe 3 O 4 nanoparticles in the ranges from 3 to 50 nm. These nanoparticles are particularly well characterized in terms of size distribution with a standard deviation (σ) in size less than 0.4 nm. We investigated the inter-particle interaction by measuring the magnetic properties of the nanoparticles while controlling inter-particle distances by diluting the samples with solvents. According to this study, blocking temperatures dropped by 8-17 K with increasing the inter-particle distances from a few nm to 140 nm while the overall shape and qualitative behavior of the magnetization remain unchanged. It implies that most features observed in the magnetic properties of the nanoparticles are due to the intrinsic properties of the nanoparticles, not due to the inter-particle interaction. We then examined possible interfacial magnetic interaction in the core-shell structure of our Fe 3 O 4 nanoparticles

    The purpose of this study was to evaluate inter-fraction error (inter-fraction set-up error+inter-fraction internal organ motion) between treatment planning and delivery during radiotherapy for localized prostate cancer. Twenty three prostate cancer patients underwent image-guided radical irradiation with the CT-linac system. All patients were treated in the supine position. After set-up with external skin markers, using CT-linac system, pretherapy CT images were obtained and isocenter displacement was measured. The mean displacement of the isocenter was 1.8 mm, 3.3 mm, and 1.7 mm in the left-right, ventral-dorsal, and cranial-caudal directions, respectively. The maximum displacement of the isocenter was 7 mm, 12 mm, and 9 mm in the left-right, ventral-dorsal, and cranial-caudal directions, respectively. The mean interquartile range of displacement of the isocenter was 1.8 mm, 3.7 mm, and 2.0 mm in the left-right, ventral-dorsal, and cranial-caudal directions, respectively. In radiotherapy for localized prostate cancer, inter-fraction error was largest in the ventral-dorsal directions. Errors in the ventral-dorsal directions influence both local control and late adverse effects. Our study suggested the set-up with external skin markers was not enough for radical radiotherapy for localized prostate cancer, thereby those such as a CT-linac system for correction of inter-fraction error being required.

    2012-01-01

    Little research focuses on the ways that bereaved family members react to and make meaning of their experience of the death of an elderly father and husband. In a qualitative, ethnographic study of 34 bereaved families we examined how family members respond to two inter-related social contexts: 1. Social-cultural values and attitudes such as attitudes toward grieving for old persons, and 2. The inter-personal dyadic relationship between interviewer and interviewee. An underlying theme of uncertainty pervades the study participants’ views of what is normal and expected in their own process of bereavement. Implications for future bereavement research are suggested. PMID:22939542

    Network virtualization has been a promising technology for overcoming the Internet impasse. A main challenge in network virtualization is the efficient assignment of virtual resources. Existing work focused on intra-domain solutions whereas inter-domain situation is more practical in realistic setting. In this paper, we present a distributed inter-domain framework for mapping virtual networks to physical networks which can ameliorate the performance of the virtual network embedding. The distributed framework is based on a Multi-agent approach. A set of messages for information exchange is defined. We design different operations and IPTV use scenarios to validate the advantages of our framework. Use cases shows that our framework can solve the inter-domain problem efficiently.

  2. Inter-municipal communities as semi-regional (quasi governments

    2014-01-01

    Full Text Available In this paper, the author discusses specific forms of integrated inter-municipal cooperation in some European countries which have certain characteristics of regional governments. Relying on the analysis of different forms of this inter-municipal cooperation, the author elaborates on some common features underlying these communities, with specific reference to their functional aspects. Bearing in mind that the imminent needs for regional planning, coordination of local policies and operation of regional offices are exercised through different institutional solutions, we point out that it is possible to provide an appropriate institutional and decentralized framework for accomplishing these goals even without changing the existing territorial organization system. Although the entities that are created through these specific forms of inter-municipal cooperation cannot be designated as territorial-political units in institutional terms, this is what they are from a functional point of view.

    Full Text Available Aluminium dust from aluminium remelting industry is a hazardous residue because of its high reactivity in the presence of water. In order to apply the new European Directive about landfill of waste, a study of its hydrolysis was carried out. The influence of temperature, time and pH on the hydrolysis of the aluminium dust was studied. The hydrolysed solids were characterized by XRD and AAS; in the aqueous solutions the pH and the ionic conductivity were determined. The evolved gases were analysed by mass spectrometry. The reactivity of the dust, before and after hydrolysis, was investigated by analysing the ammonia, hydrogen sulphide and metallic aluminium. By hydrolysis at 60 °C and 48 h a much lower reactive material was obtained which could be disposed with minimal environmental impact.

    El polvo de aluminio es un residuo generado en la metalurgia secundaria del aluminio y considerado peligroso como consecuencia de su elevada reactividad en presencia de humedad. Con objetivo de buscar un procedimiento de pretratamiento de dicho residuo, de acuerdo con la Directiva Europea sobre vertederos, se ha realizado el estudio del comportamiento del polvo de aluminio en medio acuoso. Para ello, se han analizado la influencia de la temperatura, el tiempo y el pH de reacción en su hidrólisis. Los sólidos hidrolizados se caracterizaron mediante EAA y DRX, mientras que en las soluciones acuosas resultantes se determinaron el pH y la conductividad iónica. Los gases liberados durante el proceso de hidrólisis se analizaron mediante espectrometría de masas. Asimismo, se ha determinado la reactividad del residuo antes y después de la hidrólisis, analizando amoniaco, sulfuro de hidrógeno y aluminio metálico. La hidrólisis, a 60 °C y después de 48 h, permite obtener material de muy baja reactividad que podría ser almacenado en vertedero.

    Full Text Available In this work, we study films of silicalite crystals used in gas separation processes. These crystals were obtained by hydrothermal synthesis during different times and using different gel composition. They were deposited on an alumina support growing in two preferential directions. Finally, the material was placed in a stove at 480ºC during 8 h in order to remove the structurant agent with heating and cooling rates of 0.5 y 2 ºC/min respectively. The resulting surfaces were analysed by atomic force microscopy (AFM in tapping mode in order to notice the deposition of the silicalite crystals in the indicated directions, and also to distinguish the evolution of the nuclei growth. At the same time, the porous structure of silicalite has been determined, leading to results in good agreement with those obtained by other techniques.

    En este trabajo se han estudiado láminas de silicalita con aplicación en los procesos de separación de gases. Dichas láminas se han depositado mediante síntesis hidrotermal durante distintos tiempos y usando varias composiciones en el gel precursor. La deposición se hizo sobre un soporte de alúmina con crecimiento preferencial en dos direcciones. Finalmente las láminas se calcinaron a 753 K durante 8 h para eliminar el agente estructurante, usando velocidades de calentamiento y enfriamiento de 0.5 y 1 K/min respectivamente. Las superficies resultantes se han analizado mediante microscopía de fuerza atómica en modo de contacto-intermitente (tapping con el fin de ver si efectivamente se ha conseguido depositar cristales de silicalita en las direcciones indicadas y seguir la evolución de crecimiento de los núcleos. Por otro lado, se ha determinado la estructura porosa de la silicalita comprobando que los resultados concuerdan con los obtenidos por otras técnicas.

    Full Text Available The present work is based on obtaining Co based coatings (Tribaloy T-800 on plates of 18/8 stainless steel (AISI 304 by laser cladding technique. After the treatment, samples were characterized by optical and scanning electron microscopy with EDS analysis. The elemental composition of the coating was determined with a glow discharge lamp spectrometer (GDL. The study of the interface revealed a good adherence between the substrate and coating without substantial defects. For the laser cladded coatings, the microstructure was dendritic with a high degree of refinement and chemical homogeneity close to the original powder. The grain coarsening was observed in the overlapping zones due to the second heat treatment. Microhardness of the coatings reached 750 HV, a considerably higher value than the substrate hardness (200 HV. Also, the coating corrosion resistance in saline solutions had a great improvement.

    2005-08-01

    Full Text Available Abstract Background Most proteins function by interacting with other molecules. Their interaction interfaces are highly conserved throughout evolution to avoid undesirable interactions that lead to fatal disorders in cells. Rational drug discovery includes computational methods to identify the interaction sites of lead compounds to the target molecules. Identifying and classifying protein interaction interfaces on a large scale can help researchers discover drug targets more efficiently. Description We introduce a large-scale protein domain interaction interface database called InterPare http://interpare.net. It contains both inter-chain (between chains interfaces and intra-chain (within chain interfaces. InterPare uses three methods to detect interfaces: 1 the geometric distance method for checking the distance between atoms that belong to different domains, 2 Accessible Surface Area (ASA, a method for detecting the buried region of a protein that is detached from a solvent when forming multimers or complexes, and 3 the Voronoi diagram, a computational geometry method that uses a mathematical definition of interface regions. InterPare includes visualization tools to display protein interior, surface, and interaction interfaces. It also provides statistics such as the amino acid propensities of queried protein according to its interior, surface, and interface region. The atom coordinates that belong to interface, surface, and interior regions can be downloaded from the website. Conclusion InterPare is an open and public database server for protein interaction interface information. It contains the large-scale interface data for proteins whose 3D-structures are known. As of November 2004, there were 10,583 (Geometric distance, 10,431 (ASA, and 11,010 (Voronoi diagram entries in the Protein Data Bank (PDB containing interfaces, according to the above three methods. In the case of the geometric distance method, there are 31,620 inter-chain domain

    2018-02-01

    Full Text Available In the present study, we investigated whether inter-individual differences in vagally mediated heart rate variability (vmHRV would be associated with inter-individual differences in empathy and alexithymia. To this end, we determined resting state HF-HRV in 90 individuals that also completed questionnaires assessing inter-individual differences in empathy and alexithymia. Our categorical and dimensional analyses revealed that inter-individual differences in HF-HRV were differently associated with inter-individual differences in empathy and alexithymia. We found that individuals with high HF-HRV reported more empathy and less alexithymia than individuals with low HF-HRV. Moreover, we even found that an increase in HF-HRV was associated with an increase in empathy and a decrease in alexithymia across all participants. Taken together, these findings indicate that individuals with high HF-HRV are more empathetic and less alexithymic than individuals with low HF-HRV. These differences in empathy and alexithymia may explain why individuals with high HF-HRV are more successful in sharing and understanding the mental and emotional states of others than individuals with low HF-HRV.

    One challenge of the implementation of fully-integrated RF power amplifiers into a deep submicro digital CMOS process is that no capacitor is available, especially no high density capacitor. To address this problem, a two-stage class-AB power amplifier with inter-stage matching realized by an inter-metal coupling capacitor is designed in a 180-nm digital CMOS process. This paper compares three structures of inter-metal coupling capacitors with metal-insulator-metal (MIM) capacitor regarding their capacitor density. Detailed simulations are carried out for the leakage, the voltage dependency, the temperature dependency, and the quality factor between an inter-metal shuffled (IMS) capacitor and an MIM capacitor. Finally, an IMS capacitor is chosen to perform the inter-stage matching. The techniques are validated via the design and implement of a two-stage class-AB RF power amplifier for an UHF RFID application. The PA occupies 370 x 200 mum{sup 2} without pads in the 180-nm digital CMOS process and outputs 21.1 dBm with 40% drain efficiency and 28.1 dB power gain at 915 MHz from a single 3.3 V power supply.

    This paper distinguishes relative risk aversion and resistance to inter-temporal substitution in climate risk modeling. Stochastic recursive preferences are introduced in a stylized numeric climate-economy model using preliminary IPCC 1998 scenarios. It shows that higher risk aversion increases the optimal carbon tax. Higher resistance to inter-temporal substitution alone has the same effect as increasing the discount rate, provided that the risk is not too large. We discuss implications of these findings for the debate upon discounting and sustainability under uncertainty. (author)

    level employees (middle management/employees) go through when working according to CSR-principles, based on social motives and behaviour. A hermeneutical paradigm is applied to the understanding of human (inter-) action in relation to understand a phenomenon as CSR and motives for social change....... It is suggested that the process of positive social change is divided into four phases, which to a point can be compared to The Human Learning Process by Stuart Dreyfus. Another aspect of this paper is also to create a bottom-up approach to the implementation of CSR-principles as the majority of CSR literature......The intention of this paper is to provide a specific understanding of corporate social responsibility with a particular focus in social issues in relation to human resource development. The understanding of CSR is used to create a theoretical analytical framework that should provide researchers...

    "Social opdrift - social arv" stiller på flere måder spørgsmål ved begrebet social arv. Bogen konkluderer blandt andet, at langt de fleste børn, der opvokser i en socialt belastet familie, bliver velfungerende voksne. Professionelle, der møder socialt belastede familier, har derfor et stort ansvar.......

    Full Text Available Neighbourhoods and the social use of space are areas of growing interest. By combining archaeological methods and space syntax, the article offers new insights into the physical environment of daily life in the Roman city. The detailed examination of two city blocks from Ostia (Rome’s imperial port-town, allows the authors to identify spaces which fostered social cohesion and community building. The shared courtyards and passage spaces of Block IV ii suggest continued community focus (2nd - 5th centuries AD. In contrast, Block IV iv lacks common spaces and revealed self-contained buildings centred on individual access to public space. Block IV ii enjoyed shared spaces within its own perimeter, while Block IV iv looks toward external community building, with activities centred on the street confining the block. The results show the flexibility of Roman urban structures and allow for suggestive glimpses into the community that sustained the city in the long-term.El estudio de los vecindarios y el uso social del espacio habitado son temas de interés creciente. Mediante la combinación de métodos arqueológicos y space syntax, este artículo ofrece nuevas formas de analizar el entorno físico de la vida cotidiana en las ciudades romanas. El examen detallado de dos bloques urbanos en Ostia (la ciudad portuaria de Roma en época imperial nos ha permitido identificar espacios que fomentan la cohesión social y la vida en comunidad. El uso común de patios y pasillos en el Bloque IV ii sugiere un uso comunal continuado desde el siglo II hasta el siglo V d. C. En claro contraste con este sector, el Bloque IV iv no tiene espacios comunes y muestra edificios aislados con accesos individuales al espacio público. El Bloque IV ii disfruta de espacios compartidos dentro de su propio perímetro, mientras que el Bloque IV iv parece estar orientado por el interés de comunidades externas con actividades desarrolladas hacia la calle creando cierto aislamiento

  6. Neurogenomic mechanisms of social plasticity.

    Science.gov (United States)

    Cardoso, Sara D; Teles, Magda C; Oliveira, Rui F

    2015-01-01

    Group-living animals must adjust the expression of their social behaviour to changes in their social environment and to transitions between life-history stages, and this social plasticity can be seen as an adaptive trait that can be under positive selection when changes in the environment outpace the rate of genetic evolutionary change. Here, we propose a conceptual framework for understanding the neuromolecular mechanisms of social plasticity. According to this framework, social plasticity is achieved by rewiring or by biochemically switching nodes of a neural network underlying social behaviour in response to perceived social information. Therefore, at the molecular level, it depends on the social regulation of gene expression, so that different genomic and epigenetic states of this brain network correspond to different behavioural states, and the switches between states are orchestrated by signalling pathways that interface the social environment and the genotype. Different types of social plasticity can be recognized based on the observed patterns of inter- versus intra-individual occurrence, time scale and reversibility. It is proposed that these different types of social plasticity rely on different proximate mechanisms at the physiological, neural and genomic level. © 2015.

    Full Text Available En Chile la minería se desarrolla principalmente en  la concentración de cobre, molibdeno, oro y plata, mediante el proceso de flotación. Este genera grandes tonelajes de relaves que contienen diversas minerales, principalmente pirita. Dado que estos minerales se depositan en los tranques, estos pueden generar aguas ácidas; se propone como alternativa la desulfuración de los súlfuros por flotación. En una primera parte se estudió la flotabilidad de la pirita en un tubo Hallimond, utilizando como colector AP 404. Luego se realizaron pruebas de flotación a nivel de laboratorio en celda Denver D-12, utilizando pulpa de relave fresco de la etapa rougher de un circuito de flotación de cobre,  determinando el pH óptimo y dosificación de colector y espumantes. Pruebas de cinética de flotación permitieron determinar el tiempo óptimo de flotación tanto para la etapa rougher como  para la etapa scavenger. Se concluye que la flotación de los relaves sea una técnicamente factible su desulfuración,  obteniendo relaves que contienen  0,08% de pirita.

  17. Shifting contours of boundaries: an exploration of inter-agency integration between hospital and community interprofessional diabetes programs.

    Science.gov (United States)

    Wong, Rene; Breiner, Petra; Mylopoulos, Maria

    2014-09-01

    This article reports on research into the relationships that emerged between hospital-based and community-based interprofessional diabetes programs involved in inter-agency care. Using constructivist grounded theory methodology we interviewed a purposive theoretical sample of 21 clinicians and administrators from both types of programs. Emergent themes were identified through a process of constant comparative analysis. Initial boundaries were constructed based on contrasts in beliefs, practices and expertise. In response to bureaucratic and social pressures, boundaries were redefined in a way that created role uncertainty and disempowered community programs, ultimately preventing collaboration. We illustrate the dynamic and multi-dimensional nature of social and symbolic boundaries in inter-agency diabetes care and the tacit ways in which hospitals can maintain a power position at the expense of other actors in the field. As efforts continue in Canada and elsewhere to move knowledge and resources into community sectors, we highlight the importance of hospitals seeing beyond their own interests and adopting more altruistic models of inter-agency integration.

  18. Intra- and Inter-Individual Differences in Adolescent Depressive Mood: the Role of Relationships with Parents and Friends.

    Zhang, Shiyu; Baams, Laura; van de Bongardt, Daphne; Dubas, Judith Semon

    2018-05-01

    Utilizing four waves of data from 1126 secondary school Dutch adolescents (Mage = 13.95 at the first wave; 53% boys), the current study examined the interplay between parent-adolescent and friend-adolescent relationship quality (satisfaction and conflict) in relation to adolescents' depressive mood. Using multilevel analyses, the interacting effects of parent/friend relationship quality on depressive mood were tested at both the intra- and inter-individual level. Analyses at the intra-individual level investigated whether individual depressive mood fluctuated along with changes in their social relationships regardless of one's general level of depressive mood; and analyses at the inter-individual level examined whether the average differences in depressive mood between adolescents were associated with different qualities of social relationships. We interpreted the patterns of interactions between parent and friend relationships using four theoretical models: the reinforcement, toxic friends, compensation, and additive model. The results demonstrate the covariation of parent- and friend- relationship quality with adolescents' depressive mood, and highlight that parent and peer effects are not independent from each other-affirming the compensation and additive models at the intra-individual and the reinforcement and additive models at the inter-individual level. The findings highlight the robustness of the protective effects of parent and peer support and the deleterious effects of conflictual relationships for adolescent mental health. The results have implications for both the theoretical and practical design of (preventive) interventions aimed at decreasing adolescents' depressive mood.

    2015-03-01

    Full Text Available Background: One of major areas of modern research econnected with management issues covers inter-organizational networks (including supply chains and cooperation processes aimed at improvement of the effectiveness of their performance to be found in such networks. The logistics is the main factor responsible for effectiveness of the supply chain.  A possible and a quite new direction of research in the area of the performance of processes of the inter-organizational cooperation is the proximity hypothesis that is considered in five dimensions (geographical, organizational, social, cognitive, and institutional. However, according to many authors, there is a lack of research on supply chains conducted from the logistics point of view. The proximity hypothesis in this area of research can be seen as a kind of novum. Therefore, this paper presents the proximity concept from the perspective of the management science, the overview of prior research covering the inter-organizational proximity with supply chain from the logistics point of view as well as the possible future directions of the empirical efforts. Methods: The aim of this paper is to present previous theoretical and empirical results of research covering inter-organizational proximity in logistics and to show current and up-to-date research challenges in this area. The method of the critical analysis of literature is used to realize the goal constructed this way. Results: Knowledge about the influence of the inter-organizational proximity on the performance of supply chains is rather limited, and the research conducted so far, is rather fragmentary and not free of limitations of the conceptual and methodological nature. Additional rationales for further research in this area include knowledge and cognitive gaps indentified in this paper. According to authors the aim of future empirical research should be as follows: (1 unification and update of used conceptual and methodological approaches

    2008-06-01

    Excess alcohol consumption and associated harms in terms of health, crime and disorder have been highlighted by the government and media, causing considerable public concern. This study quantified the number of patient attendances at an urban adult and children's emergency department (ED) directly attributable to alcohol intoxication, and investigated ways in which the inter-agency sharing of anonymised information could be used to design, implement and monitor interventions to reduce these harms. Intoxicated patients attending either the adult or children's ED were prospectively identified by qualified nursing staff and anonymised data collected by a dedicated researcher. Collaboration and data sharing between health, police, social services, university experts and local authorities was achieved through the establishment of steering and operational groups with agreed objectives and the formation of a shared anonymised database. The proportion of patients attending the ED as a result of alcohol intoxication was 4% in adults and <1% in children. 70% of patients were male, with a mean age of 30 years, and 72% attended between 20.00 and 08.00 h. The most common reason for ED attendance was accident (34%), followed closely by assault (30%). 27% of patients had done most of their drinking at home, 36% in a pub and 16% in a nightclub. Inter-agency collaboration proved highly successful: pooling of anonymised data created a much clearer picture of the extent of the problem and immediately suggested strategies for intervention. The initiative to achieve inter-agency collaboration and data sharing was highly successful, with clear potential for the development and implementation of interventions that will reduce ED attendance due to excess alcohol consumption.

    2006-10-01

    Five consecutive cases of prosthetic inter-vertebral disc displacement with severe vascular complications on revisional surgery are described. The objective of this case report is to warn spinal surgeons that major vascular complications are likely with anterior displacement of inter-vertebral discs. We have not been able to find a previous report on vascular complications associated with anterior displacement of prosthetic inter-vertebral discs. In all five patients the prosthetic disc had eroded into the bifurcation of the inferior vena cava and the left common iliac vein. In three cases the aortic bifurcation was also involved. The fibrosis was so severe that dissecting out the arteries and veins to provide access to the relevant disc proved impossible. Formal division of the left common iliac vein and artery with subsequent repair was our solution. Anterior inter-vertebral disc displacement was associated with severe vascular injury. Preventing anterior disc displacement is essential in disc design. In the event of anterior displacement, disc removal should be planned with a Vascular Surgeon.

    Tensions on the Korean Peninsula remain high despite a long-term strategy by South Korea to increase inter-Korean exchanges in economics, culture, sports, and other topics. This is because the process of reconciliation has rarely extended to military and security topics and those initiatives that were negotiated have been ineffective. Bilateral interactions must include actions to reduce threats and improve confidence associated with conventional military forces (land, sea, and air) as well as nuclear, chemical, and biological activities that are applicable to developing and producing weapons of mass destruction (WMD). The purpose of this project is to develop concepts for inter-Korean confidence building measures (CBMs) for military and WMD topics that South Korea could propose to the North when conditions are right. This report describes the historical and policy context for developing security-related CBMs and presents an array of bilateral options for conventional military and WMD topics within a consistent framework. The conceptual CBMs address two scenarios: (1) improved relations where construction of a peace regime becomes a full agenda item in inter-Korean dialogue, and (2) continued tense inter-Korean relations. Some measures could be proposed in the short term under current conditions, others might be implemented in a series of steps, while some require a higher level of cooperation than currently exists. To support decision making by political leaders, this research focuses on strategies and policy options and does not include technical details.

  20. Inter-electrode delay estimators for electrohysterographic propagation analysis

    Premature birth is a major cause of mortality and permanent dysfunctions. Several parameters derived from single channel electrohysterographic (EHG) signals have been considered to determine contractions leading to preterm delivery. The results are promising, but improvements are needed. As effective uterine contractions result from a proper action potential propagation, in this paper we focus on the propagation properties of EHG signals, which can be predictive of preterm delivery. Two standard delay estimators, namely maximization of the cross-correlation function and spectral matching, are adapted and implemented for the assessment of inter-electrode delays of propagating EHG signals. The accuracy of the considered standard estimators might be hampered by a poor inter-channel correlation. An improved dedicated approach is therefore proposed. By simultaneous adaptive estimation of the volume conductor transfer function and the delay, a dedicated method is conceived for improving the inter-channel signal similarity during delay calculation. Furthermore, it provides delay estimates without resolution limits and it is suitable for low sampling rates, which are appropriate for EHG recording. The three estimators were evaluated on EHG signals recorded on seven women. The dedicated approach provided more accurate estimates due to a 22% improvement of the initial average inter-channel correlation

  18. Strange-face illusions during inter-subjective gazing.

    Science.gov (United States)

    Caputo, Giovanni B

    2013-03-01

    In normal observers, gazing at one's own face in the mirror for a few minutes, at a low illumination level, triggers the perception of strange faces, a new visual illusion that has been named 'strange-face in the mirror'. Individuals see huge distortions of their own faces, but they often see monstrous beings, archetypal faces, faces of relatives and deceased, and animals. In the experiment described here, strange-face illusions were perceived when two individuals, in a dimly lit room, gazed at each other in the face. Inter-subjective gazing compared to mirror-gazing produced a higher number of different strange-faces. Inter-subjective strange-face illusions were always dissociative of the subject's self and supported moderate feeling of their reality, indicating a temporary lost of self-agency. Unconscious synchronization of event-related responses to illusions was found between members in some pairs. Synchrony of illusions may indicate that unconscious response-coordination is caused by the illusion-conjunction of crossed dissociative strange-faces, which are perceived as projections into each other's visual face of reciprocal embodied representations within the pair. Inter-subjective strange-face illusions may be explained by the subject's embodied representations (somaesthetic, kinaesthetic and motor facial pattern) and the other's visual face binding. Unconscious facial mimicry may promote inter-subjective illusion-conjunction, then unconscious joint-action and response-coordination. Copyright © 2012 Elsevier Inc. All rights reserved.

  8. Values, inter-attitudinal structure, and attitude change: value accessibility can increase a related attitude's resistance to change.

    Science.gov (United States)

    Blankenship, Kevin L; Wegener, Duane T; Murray, Renee A

    2015-12-01

    Accessibility is one of the most basic structural properties of an attitude and an important factor to consider in attitude strength. Despite its importance, relatively little work has examined the role of attitude accessibility in an inter-attitudinal context, particularly as it relates to the strength of related attitudes in the network. The present research examines accessibility as a property of one attitude (toward an abstract goal or end-state, that is, a value) that might influence the strength of a different but related attitude (toward a social policy conceptually related to the value). In Study 1, a highly accessible evaluative component of a value increased resistance to change of attitudes and behavioral intentions toward a social policy related to that value. Similarly, a manipulation of value accessibility (Studies 2 and 3) led to increased resistance of attitudes and behavioral intentions toward a social policy related to that value. Implications for the role of accessibility in inter-attitudinal strength are discussed. © 2015 by the Society for Personality and Social Psychology, Inc.

  13. Practical methodological guide for hydrometric inter-laboratory organisation

    Science.gov (United States)

    Besson, David; Bertrand, Xavier

    2015-04-01

    Discharge measurements performed by the French governmental hydrometer team feed a national database. This data is available for general river flows knowkedge, flood forecasting, low water survey, statistical calculations flow, control flow regulatory and many other uses. Regularly checking the measurements quality and better quantifying its accuracy is therefore an absolute need. The practice of inter-laboratory comparison in hydrometry particularly developed during the last decade. Indeed, discharge measurement can not easily be linked to a standard. Therefore, on-site measurement accuracy control is very difficult. Inter-laboratory comparison is thus a practical solution to this issue. However, it needs some regulations in order to ease its practice and legitimize its results. To do so, the French government hydrometrics teams produced a practical methodological guide for hydrometric inter-laboratory organisation in destination of hydrometers community in view of ensure the harmonization of inter-laboratory comparison practices for different materials (ADCP, current meter on wadind rod or gauging van, tracer dilution, surface speed) and flow range (flood, low water). Ensure the results formalization and banking. The realisation of this practice guide is grounded on the experience of the governmental teams & their partners (or fellows), following existing approaches (Doppler group especially). The guide is designated to validate compliance measures and identify outliers : Hardware, methodological, environmental, or human. Inter-laboratory comparison provides the means to verify the compliance of the instruments (devices + methods + operators) and provides methods to determine an experimental uncertainty of the tested measurement method which is valid only for the site and the measurement conditions but does not address the calibration or periodic monitoring of the few materials. After some conceptual definitions, the guide describes the different stages of an

    Full Text Available RESUMEN El análisis de masas y tumores en mamografía es un problema difícil porque los signos del cáncer pueden ser mínimos o estar superpuestos en el tejido. Las técnicas de procesamiento de imágenes pueden mejorar el diagnóstico reduciendo los costos. La detección de masas es un reto debido al bajo contraste y la pobre definición de los bordes. Una solución al problema es representar una masa mediante conjuntos difusos. En este trabajo se estudia la propuesta de Guliato et al. que plantean dos métodos de segmentación difusos. El primero determina el borde de una masa por crecimiento por regiones clásico, luego de un preprocesamiento difuso de la región de interés. El segundo es un método de crecimiento por regiones difuso. Estos métodos necesitan un píxel semilla y un umbral. En este trabajo se propone una selección automática del píxel semilla mediante la selección de píxeles muy correlacionados según la transformada wavelet de la imagen. Como medida de evaluación en la segmentación, se emplea la medida de ambigüedad definida por los autores citados. Con la selección de semilla propuesta se obtienen mejores resultados en la segmentación, respecto al uso de una semilla aleatoria. ABSTRACT The analysis of masses and tumors in mammography is difficult because developing signs of cancer may be minimal or masked by superimposed tissues. Image analysis techniques have the potential to improve the diagnostic accuracy of mammography, and reduce health-care costs. Detection of breast masses is a challenging problem due to low contrast and poor definition of their boundaries. An alternative to address this problem is to represent tumor or mass regions by fuzzy sets. In this paper, two methods of fuzzy segmentation proposed by Guliato et al. are studied. The first method determines the boundary of a mass by classic region growing after a fuzzy preprocessing step. The second method is a fuzzy region-growing method. This

  18. A Methodological Inter-Comparison of Gridded Meteorological Products

    Science.gov (United States)

    Newman, A. J.; Clark, M. P.; Longman, R. J.; Giambelluca, T. W.; Arnold, J.

    2017-12-01

    Here we present a gridded meteorology inter-comparison using the state of Hawaíi as a testbed. This inter-comparison is motivated by two general goals: 1) the broad user community of gridded observation based meteorological fields should be aware of inter-product differences and the reasons they exist, which allows users to make informed choices on product selection to best meet their specific application(s); 2) we want to demonstrate the utility of inter-comparisons to meet the first goal, yet highlight that they are limited to mostly generic statements regarding attribution of differences that limits our understanding of these complex algorithms and obscures future research directions. Hawaíi is a useful testbed because it is a meteorologically complex region with well-known spatial features that are tied to specific physical processes (e.g. the trade wind inversion). From a practical standpoint, there are now several monthly climatological and daily precipitation and temperature datasets available that are being used for impact modeling. General conclusions that have emerged are: 1) differences in input station data significantly influence product differences; 2) prediction of precipitation occurrence is crucial across multiple metrics; 3) derived temperature statistics (e.g. diurnal temperature range) may have large spatial differences across products; and 4) attribution of differences to methodological choices is difficult and may limit the outcomes of these inter-comparisons, particularly from a development viewpoint. Thus, we want to continue to move the community towards frameworks that allow for multiple options throughout the product generation chain and allow for more systematic testing.

  19. Review of inter-utility trade in electricity

    International Nuclear Information System (INIS)

    1994-01-01

    In 1992, Canada's National Energy Board released two discussion papers on inter-utility trade. Responses to the papers were received from utilities, government agencies, and other interested parties with regard to questions concerning measures that could be taken to enhance interprovincial trade in electricity and to enable buyers and sellers of electricity to obtain commercial access to available transmission capacity through intermediate provinces for wheeling purposes. The Board's review had estimated long-term net benefits from enhanced inter-utility cooperation at $23-32.5 billion by the year 2000 from such types of transactions as seasonal diversity exchanges and long-term firm sales. Seven types of options to achieve enhanced inter-utility trade were identified. Most of the respondent utilities and provinces that have direct access to external markets tended to prefer the status quo, opposing mandated solutions but supporting (or at least not opposing) federal monitoring of progress on enhanced inter-utility cooperation. Provinces and utilities without direct access to external markets tended to support (as a last resort) mandated solutions to disputes concerning electricity trade. Since the Board review, important events in the North American electricity supply industry have occurred; these are described, focusing on the US Energy Policy Act that gives powers to order transmission access.

    Intra-system common-cause failures (CCF) are widely studied and addressed in existing PSA models, but the information and studies that incorporate the potential for inter-system CCF is limited. However, the French Safety Authority has requested that EDF investigate the possibility of common-cause failure across system boundaries for Flamanville 3 (an EPR design). Also, the modeling of inter-system CCF, or the proof that their impact is negligible, would satisfy Capability Category III for one of the requirements in the ASME/ANS PRA standard in the U.S. EDF and EPRI have been working on a method to assess when it is necessary to take into account inter-system CCF in a PSA model between 2008 and 2010. This method is based both on the likelihood of inter-system CCF and on its demonstrated potential impact on CDF (core damage frequency). This method was first applied on pumps in different systems of the 900 MWe series plants. The second application concerned the motor-operated valves across different systems, using the same PSA model. This second application helped us refine the method, which was not optimal when the number of concerned components is very large. Since then, the method has been successfully applied on the pumps and 10 kV breakers of the EPR power plant in Flamanville. This paper describes the method and the results obtained in some of these studies. All studies have shown either that components in different systems, when they were not already part of a common cause failure group in the model, are not susceptible to common causes of failure, or that the potential for inter-system common-cause failure is negligible regarding the overall risk.

    Full Text Available El ejercicio físico practicado con regularidad aporta varios beneficios para la salud, pero solamente una cuarta parte de los adultos en Estados Unidos de América hacen ejercicio en las cantidades recomendadas semanalmente. Además, muchos adultos y adolescentes en ese país dicen no practicar con regularidad un ejercicio físico moderado o intenso. Para ayudar a remediar esta situación, un grupo de salubristas estadounidenses llevó a cabo una revisión sistemática de intervenciones que podrían redundar en un aumento de la actividad física. El grupo, conocido por Grupo de Trabajo sobre Servicios Comunitarios Preventivos [Task Force on Community Preventive Services] fue convocado por el Departamento de Salud y Servicios Humanos del Gobierno de Estados Unidos, aunque es independiente de esta entidad. El Grupo de Trabajo recomendó dos enfoques informativos (campañas comunitarias y recordatorios en los puntos de decisión para fomentar el uso de escaleras, tres enfoques conductuales y sociales (educación física en las escuelas, intervenciones de apoyo social en contextos comunitarios, como un sistema de trabajo con pares o de pacto con otras personas para alcanzar niveles específicos de actividad física, y programas de modificación conductual de orientación individual; y una intervención orientada a aumentar la actividad física mediante un enfoque ambiental y político (creando o facilitando acceso a sitios donde hacer ejercicio, junto con actividades informáticas proactivas. El Grupo de Trabajo no encontró datos suficientes para recomendar o no cinco intervenciones adicionales.

    Perreault, Kadija; Dionne, Clermont E; Rossignol, Michel; Poitras, Stéphane; Morin, Diane

    Purpose : Although there have been increasing demands for health care providers to take part in inter-professional practices in recent years, very little attention has been paid to the actualization of such practices in the private sector. This study describes private-sector physiotherapists' inter-professional practices regarding low back pain (LBP) management and identifies organizational and provider-level variables associated with the intensity of such practices. Method : A total of 327 randomly selected physiotherapists were surveyed in the province of Quebec. Data were analyzed using descriptive and multiple regression analyses. Results : Physiotherapists reported frequent interactions with other physiotherapists (daily/weekly for 52.6%), family physicians (51.0%), and physiotherapy (PT) assistants (45.2%), but infrequent interactions with psychologists (3.6%), neurosurgeons (0.9%), and chiropractors (0.3%). Frequently reported means of interactions were written and oral messages sent through clients (55.1% and 24.1%, respectively), face-to-face unplanned discussions (41.9%), and faxed or mailed letters (23.2%). Variables associated with the intensity of inter-professional practices (mean of 6.7 [ SD 1.7] out of 10 on the Intensity of Interprofessional Practices Questionnaire for Private Sector Physiotherapists) were related to physiotherapists' clientele, social activities with other providers, and perceptions of inter-professional practices as well as organizational models, vision, and provision of PT training. Conclusions: There is room to improve inter-professional practices with private-sector physiotherapists involved in managing LBP. Targets for action include physiotherapists and their workplaces.

    Analysis of task-based fMRI data is conventionally carried out using a hypothesis-driven approach, where blood-oxygen-level dependent (BOLD) time courses are correlated with a hypothesized temporal structure. In some experimental designs, this temporal structure can be difficult to define. In other cases, experimenters may wish to take a more exploratory, data-driven approach to detecting task-driven BOLD activity. In this study, we demonstrate the efficiency and power of an inter-subject synchronization approach for exploratory analysis of task-based fMRI data. Combining the tools of instantaneous phase synchronization and independent component analysis, we characterize whole-brain task-driven responses in terms of group-wise similarity in temporal signal dynamics of brain networks. We applied this framework to fMRI data collected during performance of a simple motor task and a social cognitive task. Analyses using an inter-subject phase synchronization approach revealed a large number of brain networks that dynamically synchronized to various features of the task, often not predicted by the hypothesized temporal structure of the task. We suggest that this methodological framework, along with readily available tools in the fMRI community, provides a powerful exploratory, data-driven approach for analysis of task-driven BOLD activity.

    Purpose: The aim of this study was to compare inter-individual and inter-cell type variation in DNA double-strand break (DSB) repair following in vivo irradiation of human skin. Materials and methods: Duplicate 4 mm core biopsies of irradiated and unirradiated skin were collected from 35 patients 24 h after 4 Gy exposure using 6 MeV electrons. Residual DSB were quantified by scoring 53BP1 foci in dermal fibroblasts, endothelial cells, superficial keratinocytes and basal epidermal cells. Results: Coefficients of inter-individual variation for levels of residual foci 24 h after in vivo irradiation of skin were 39.9% in dermal fibroblasts, 44.3% in endothelial cells, 32.9% in superficial keratinocytes and 46.4% in basal epidermal cells (p < 0.001, ANOVA). In contrast, the coefficient of inter-cell type variation for residual foci levels was only 11.3% in human skin between the different epidermal and dermal cells (p = 0.034, ANOVA). Foci levels between the different skin cell types were correlated (Pearson's R = 0.855-0.955, p < 0.001). Conclusions: Patient-specific factors appear to be more important than cell type-specific factors in determining residual foci levels following in vivo irradiation of human skin.

    Full Text Available In this work, we present the application of ultrashort and intense laser pulses (110 fs @ 1 kHz; up to 1.1 mJ/pulse to the micromachining of ceramics, specifically RubalitTM708S, a material based on alumina and widely used as a substrate in microelectronics. The mechanism for removing material is the so called direct ablation. It differs from thermal ablation of conventional lasers in the practically total absence of thermal effects which produces a remarkable increase of quality and precision of the machining. By means of an optical diffraction-based technique we find out the energy density threshold to work in the direct ablation regime. Adjusting the energy per pulse as well as the number of pulses, we are able to drill holes of the desired diameter and depth. In addition, processing is developed in air. We also demonstrate that high quality fs-laser micromachining is suitable for every ceramic, whatever the mechanical properties, with similar working parameters. In order to show this point, we have also processed sintered SiN, a material of wide-ranging interest in industry.

El mecanismo de eliminación de material es la ablación directa, que difiere de la ablación térmica empleada por los láseres convencionales en la prácticamente total ausencia de efectos térmicos, lo que redunda en un aumento significativo de la precisión y calidad del mecanizado. Mediante técnicas basadas en la difracción óptica determinamos el umbral de energía necesario para que tenga lugar el proceso de ablación directa. Con ese dato y regulando la energía por pulso y el número de pulsos somos capaces de producir mecanizados del diámetro y profundidad deseados. Además, el

    Full Text Available The addition of Ag into Bi-2212 compounds has demonstrated to be a suitable method to improve both, the thermal and mechanical properties as well as the electrical ones. The final properties have been found to be in strong dependence of Ag content and the processing technique. In the present work the influence of Ag addition on Bi-2212 bulk materials grown from the melt, using a laser floating zone melting technique, has been studied. Samples with different Ag contents (0 to 40 wt.% were prepared for this work. The Bi-2212 + x wt.% Ag powders have been prepared by a sol-gel method via nitrates to assure total cation solution, small particle size and good homogeneity in the mixture. Cylindrical precursors, fabricated from these powders, were used as feed in a LFZ melting installation to obtain textured Bi-2212/Ag composites. The effect of the Ag addition on the microstructure is analysed as a function of Ag content. The changes on the microstructure are also correlated with the mechanical and superconducting properties.

    La incorporación de Ag en los compuestos de Bi-2212 ha demostrado ser un método adecuado para mejorar tanto las propiedades mecánicas, térmicas como eléctricas de estos materiales. Las propiedades finales dependen fuertemente de la cantidad de Ag añadida al sistema pero también del tipo de procesado que sufre. En el presente trabajo se realiza un estudio del efecto de la adición de Ag en materiales masivos Bi-2212 texturados mediante fusión zonal inducida por láser, con el objetivo de comprender el efecto de la adición de Ag en sistemas Bi-2212 que pasan totalmente por un fundido. Para ello se preparon muestras con diferentes contenidos en Ag (hasta el 40% en peso. Debido a la inmiscibilidad en estado sólido de la Ag y del Bi-2212, se ha utilizado un método de síntesis de estos materiales por medio de técnicas sol-gel para asegurar una buena homogeneidad y un tamaño de partícula reducido en la cerámica de

    In 1990 the Instituto de Ingenieria de la UNAM, initiated an evaluation through the soil and groundwater sampling and a risk health assessment in a Mexican refinery. An extended area was found contaminated with hydrocarbons. This area requires a soil remediation, taking into account that some zones present more than 30 000 mg/kg of Total Petroleum Hydrocarbons (TPH). Biopile system was recommended as the best remediation method to diminish TPG and some poliaromathic hydrocarbons (PAH). Therefore an experimental biopile of 30 m3 was constructed with contaminated soil. After 22 weeks, results show more than 80 % of TPH and PAH remotion. [Spanish] El grupo de saneamiento de suelos y acuiferos del Instituto de Ingenieria de la UNAM, inicio en 1999 la evaluacion de la contaminacion del subsuelo de una refineria en una zona costera del pais, mediante el muestreo de 425 puntos a 1.5 m de profundidad y con el analisis de los siguientes parametros: hidrocarburos totales del petroleo (HTP), hidrocarburo poliaromaticos (HAP), diesel, gasolina, metilterbutileter (MTBE) y los metales hierro, vanadio, zinc, cadmio, cromo y plomo. Asimismo, se lleva a cabo una evaluacion de riesgo a la salud a fin de determinar los niveles de limpieza de las areas contaminadas.

    Full Text Available En este trabajo se presenta un método de estimación y simulación de un modelo aditivo a dos variables mediante splines robustos, el método general puede ser aplicado con varias variables. El software utilizado para las simulaciones es S+ y se utiliza explícitamente la función smooth.splineRob en una implementación del algoritmo de backfitting. La función smooth.splineRob ha sido escrita en base al trabajo de Cantoni y Ronchetti [3], en el cual se pone énfasis en la selección robusta del parámetro de suavizamiento utilizando una versión robusta del Cp de Mallows, RCp, y de la validación cruzada, RCV. La existencia de datos extremos o no-normales en la parte estocástica de un modelo aditivo puede provocar una mala estimación del parámetro de suavizamiento, lo que tendrá influencia global en la estimación por splines. Para la etapa de simulación se realizan las estimaciones por splines clásicos y robustos (con estimación robusta del parámetro. La estimación obtenida es muy convincente pero el tiempo de ejecución del programa es relativamente elevado tanto para RCp y RCV, aun cuando, en ciertos casos, con pocas iteraciones robustas se obtienen ya resultados más útiles que la estimación clásica.

    Full Text Available Las redes de Petri son ideales para describir y estudiar sistemas que procesan información y con características concurrentes, asíncronas, distribuidas, paralelas, no determinísticas y/o estocásticas. . Sin embargo, la teoría clásica de estas redes se enfrenta al desafío de adecuarse a las nuevas necesidades de los sistemas informáticos que los ingenieros diseñan en la actualidad. Un diagrama de actividades representa una secuencia de actividades. Podría aplicarse a cualquier propósito, pero se considera especialmente útil para visualizar los flujos de trabajo y los procesos del negocio, o casos de uso. El presente trabajo se ha desarrollado con el objetivo de diseñar un método para el modelado y prueba de diagramas de actividades mediante redes de Petri. El método propuesto brinda una serie de pasos necesarios para modelar un diagrama de actividades con redes de Petri y a partir de dicha red obtener una representación matemática de la misma. Esta representación matemática se utiliza para con ella realizar una serie de operaciones basadas en el marcaje de la red que permiten realizar pruebas al diagrama. Este método es capaz de identificar errores comunes que se cometen en el modelado de los diagramas de actividades, lo cual se demostró a través del método de experimentación.

    Full Text Available El colgajo en piedra clave (Keystone Perforator Island Flap KPIF, es un colgajo local fasciocutáneo en isla que no requiere identificación de perforantes, descrito por Behan en 2003, que permite el cierre en un único acto quirúrgico tanto del defecto como de la zona dadora sin precisar, generalmente, autoinjerto cutáneo. Nuestro objetivo es el mostrar la utilidad de este colgajo para la cobertura de defectos amplios en tronco. De los más de 120 casos realizados en nuestro Servicio con esta técnica sin tener en cuenta la localización del problema entre abril de 2011 y abril de 2013, presentamos 5 casos que, tras resección quirúrgica por diferentes etiologías, fueron los que presentaron defectos de cobertura de mayor tamaño en tronco (entre 10 y 25 cm de diámetro máximo que fueron solventados satisfactoriamente mediante el KPIF. En todos obtuvimos un cierre directo tanto de la zona del defecto como de la zona dadora, sin complicaciones durante el acto quirúrgico ni en el postoperatorio, con resultados estéticos óptimos, sin deformidades significativas ni alteraciones funcionales. Creemos que el KPIF es un colgajo óptimo para la cobertura de defectos amplios en el tronco ya que permite cubrir el defecto y hacer un cierre primario de la zona dadora generando poca morbilidad, con un buen resultado estético, con un corto tiempo quirúrgico y con un bajo coste.

    Full Text Available El desarrollo de proyectos de software considera importante la consistencia entre la información entregada por todos los interesados de una aplicación. En otras palabras, se procura llegar a acuerdos entre los diferentes puntos de vista de cada actor y llevarlos a cabo durante todo el proyecto. Con los métodos de enseñanza tradicionales se procura formar habilidades en este campo, pero no se afianzan mediante la práctica que, generalmente, se emplea para el aprendizaje en este campo. Por ello, en este artículo se propone ''PoV-GAME'', una nueva forma de ''jugar aprendiendo'', la cual busca fortalecer algunos conceptos básicos en la ingeniería de software como la consistencia en la información que se maneja a lo largo de un proyecto y afianzar la importancia de los puntos de vista en el desarrollo de un producto de software. Posteriormente, se analizan los resultados obtenidos luego de realizar el juego en diferentes grupos de estudiantes.Information for software applications is delivered by the stakeholders. Software development projects need consistency as an important aspect of such information. In other words, agreement among the different viewpoints must be reached in order to be implemented in the project. Well-known teaching methods try to create capabilities in this field, but they fail in reinforcing them in practice, which is commonly used for teaching in this field. Therefore, in this paper we propose ''PoV GAME'' a new way of ''play-to-learn''. We aim the reinforcement of some basic concepts about software engineering such as consistency in the information handled throughout the project, and the importance of viewpoints in the software product development. Subsequently, we analyze the results obtained after holding the game in several groups of students.

Por lo tanto, es recomendable evaluar dichos tratamientos durante mayor tiempo, además de evaluarlos en campo.

    Full Text Available En la zona de Poasito de Alajuela, se evaluó la acción del antagonista Gliocladium roseum, en forma individual y en conjunto con los fungicidas empleados en la finca, para el combate de Botrytis cinerea en fresa; comparándose los resultados contra los obtenidos con el manejo comercial. Se empleó un diseño de bloques completos al azar con 4 repeticiones y se hicieron aplicaciones semanales del antagonista (a una concentración ³ 107 conidios ml-1 durante un período aproximado de 4 meses (julio-octubre del 2000. Se evaluó la incidencia de moho gris en condiciones de campo y poscosecha, así como el efecto de los fungicidas aplicados sobre la germinación de los conidios del antagonista, mediante una prueba in vitro. Se obtuvo un combate más efectivo de la enfermedad en condiciones de campo al emplear el biocontrolador sólo o en conjunto con los fungicidas, con respecto al manejo comercial que se hace de la misma. En poscosecha, el desempeño del antagonista fue estadísticamente igual al del combate químico. Estos resultados muestran que los fungicidas aplicados no afectan considerablemente al antagonista, lo que se corroboró con la prueba in vitro. Al emplear G. roseum para el combate de B. cinerea no sólo se logra combatir efectivamente a este, sino también el resto de los patógenos (Colletotrichum, Phytophthora, Rhizoctonia, Rhizopus,Alternaria, Fusarium, Verticillium y Penicillium, ya que el porcentaje de frutas sanas es mayor al integrar la acción del antagonista al manejo de enfermedades de la finca. Sin embargo, estas diferencias no son estadísticamente significativas. Por lo anterior se concluye que G. roseum constituye una posible alternativa de manejo integrado del moho gris en fresa.
