In the management of natural or technological hazards in a society, the objective should be to serve the public interest in a rational manner. Decisions with regard to risk levels for the public - if they are to be defensible and self-consistent - require an integrated system of values that covers the entire range of hazards under public regulation. The process for setting risk levels (or safety goals) should ideally involve a thorough consideration of cost and benefit of all kinds, supported by explicit quantified comparison on a widely acceptable scale. The purpose of the paper is to show how quantitative criteria within the context of an appropriate framework can be used to guide risk management decisions. Social indicators are time series, statistics that reflect some aspect of the quality of life in a society or group of individuals. Development, validation, and use of social indicators is an important current research activity, as exemplified by journals such as Social Indicators Research. The basic objective is to provide quantitative measures for assessing the rationales and effectiveness of public decision-making. The concept is applicable to the nuclear industry

Hidden multidimensional social structure modeling applied to biased social perception

Maletić, Slobodan; Zhao, Yi

Intricacies of the structure of social relations are realized by representing a collection of overlapping opinions as a simplicial complex, thus building latent multidimensional structures, through which agents are, virtually, moving as they exchange opinions. The influence of opinion space structure on the distribution of opinions is demonstrated by modeling consensus phenomena when the opinion exchange between individuals may be affected by the false consensus effect. The results indicate that in the cases with and without bias, the road toward consensus is influenced by the structure of multidimensional space of opinions, and in the biased case, complete consensus is achieved. The applications of proposed modeling framework can easily be generalized, as they transcend opinion formation modeling.

The social structure of schooling.

Science.gov (United States)

Dornbusch, S M; Glasgow, K L; Lin, I C

1996-01-01

The term social structure refers to a relatively enduring pattern of social arrangements or interrelations within a particular society, organization, or group. This chapter reviews how the social structure of the larger society and the organizational structure of schools affect the educational process within American schools. The institutional context of schooling is first discussed. The ideology of mass education, social stratification, status attainment, credentialism, and the emphasis on ability differences are considered. The focus then shifts to the organizational structure of schools, beginning with a discussion of the external social context for school organization. Attention is given to professionalism and bureaucracy, institutional forms of organization, decentralized control, and community influences. Finally, the internal structure of school organization is considered: teachers' working conditions, status differences among students, and curriculum tracking. Throughout, the emphasis is on ways in which social structure influences what is taught in school, how it is taught, and what is learned.

Measuring corporate social responsibility using composite indices: Mission impossible? The case of the electricity utility industry

Directory of Open Access Journals (Sweden)

Juan Diego Paredes-Gazquez

2016-01-01

Full Text Available Corporate social responsibility is a multidimensional concept that is often measured using diverse indicators. Composite indices can aggregate these single indicators into one measurement. This article aims to identify the key challenges in constructing a composite index for measuring corporate social responsibility. The process is illustrated by the construction of a composite index for measuring social outcomes in the electricity utility industry. The sample consisted of seventy-four companies from twenty-three different countries, and one special administrative region operating in the industry in 2011. The findings show that (1 the unavailability of information about corporate social responsibility, (2 the particular characteristics of this information and (3 the weighting of indicators are the main obstacles when constructing the composite index. We highlight than an effective composite index should has a clear objective, a solid theoretical background and a robust structure. In a practical sense, it should be reconsidered how researchers use composite indexes to measure corporate social responsibility, as more transparency and stringency is needed when constructing these tools.

Social inheritance can explain the structure of animal social networks

The social network structure of animal populations has major implications for survival, reproductive success, sexual selection and pathogen transmission of individuals. But as of yet, no general theory of social network structure exists that can explain the diversity of social networks observed in nature, and serve as a null model for detecting species and population-specific factors. Here we propose a simple and generally applicable model of social network structure. We consider the emergence of network structure as a result of social inheritance, in which newborns are likely to bond with maternal contacts, and via forming bonds randomly. We compare model output with data from several species, showing that it can generate networks with properties such as those observed in real social systems. Our model demonstrates that important observed properties of social networks, including heritability of network position or assortative associations, can be understood as consequences of social inheritance.

Language structure is partly determined by social structure.

Directory of Open Access Journals (Sweden)

Gary Lupyan

Full Text Available BACKGROUND: Languages differ greatly both in their syntactic and morphological systems and in the social environments in which they exist. We challenge the view that language grammars are unrelated to social environments in which they are learned and used. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a statistical analysis of >2,000 languages using a combination of demographic sources and the World Atlas of Language Structures--a database of structural language properties. We found strong relationships between linguistic factors related to morphological complexity, and demographic/socio-historical factors such as the number of language users, geographic spread, and degree of language contact. The analyses suggest that languages spoken by large groups have simpler inflectional morphology than languages spoken by smaller groups as measured on a variety of factors such as case systems and complexity of conjugations. Additionally, languages spoken by large groups are much more likely to use lexical strategies in place of inflectional morphology to encode evidentiality, negation, aspect, and possession. Our findings indicate that just as biological organisms are shaped by ecological niches, language structures appear to adapt to the environment (niche in which they are being learned and used. As adults learn a language, features that are difficult for them to acquire, are less likely to be passed on to subsequent learners. Languages used for communication in large groups that include adult learners appear to have been subjected to such selection. Conversely, the morphological complexity common to languages used in small groups increases redundancy which may facilitate language learning by infants. CONCLUSIONS/SIGNIFICANCE: We hypothesize that language structures are subjected to different evolutionary pressures in different social environments. Just as biological organisms are shaped by ecological niches, language structures appear to adapt to the

Do adversarial environmental conditions create social cohesion? We provide new answers to this question by exploiting spatial and temporal variation in exposure to earthquakes across Chile. Using a variety of methods and controlling for a number of socio-economic variables, we find that exposure to earthquakes has a positive effect on several indicators of social cohesion. Social cohesion increases after a big earthquake and slowly erodes in periods where environmental conditions are less adverse. Our results contribute to the current debate on whether and how environmental conditions shape formal and informal institutions.

Social network indices in the Generations and Gender Survey: An appraisal

Directory of Open Access Journals (Sweden)

Pearl A. Dykstra

2016-06-01

Full Text Available Background: In this contribution we critically appraise the social network indices in the Generations and Gender Survey (GGS. Objective: After discussing the rationale for including social network indices in the GGS, we provide descriptive information on social network characteristics and an overview of substantive questions that have been addressed using GGS social network data: antecedents and consequences of demographic behaviour, care, and differences in well-being. We identify topics that have received relatively little attention in GGS research so far, despite the availability of novel and appropriate social network data. We end with a discussion of what is unique about the social network indices in the GGS. Methods: The descriptive information on social network characteristics is based on empirical analyses of GGS data, and an experimental pilot study. The overview of GGS research using social network indices is based on a library search. The identification of what is unique about the social network indices in the GGS is based on a comparison with the European Quality of Life Survey (EQLS, the Survey of Health, Ageing and Retirement (SHARE, and the International Social Survey Program (ISSP. Results: Results show a high representation of family members in the social networks, and confirm the adequacy of using a cap of five names for network-generating questions. GGS research using the social network indices has largely focused on determinants of fertility behaviour, intergenerational linkages in families, and downward care transfers. Conclusions: Topics that have received relatively little attention are demographic behaviours other than those related to parenthood, upward transfers of practical support, ties with siblings, and stepfamily ties. Social network indices in the GGS show a high degree of overlap with those in other international surveys. The unique features are the inventory of family ties ever born and still living, and the

Construction of corporate social performance indicators for Czech manufacturing industry

2013-01-01

Full Text Available This article aims to map out the level of social performance measurement of Czech companies, i.e. what social performance indicators companies monitor and what information they provide to their stakeholders and to construct alternative corporate social performance indicators. Based on an analysis of 24 corporate voluntary reports and results of an empirical research performed among 79 large companies operating in the manufacturing industry, it was found that companies partially monitor their social performance, but from the perspective of international standards (e.g. Global Reporting Initiative, International Federation of Accountants it is still insufficient. Czech companies usually provide only absolute numbers which disguise real trends and do not allow year on year comparison or comparison with other companies. Czech companies should provide a comprehensive picture of their overall performance, they should not focus only on financial indicators based on accounting data, since it is known that the performance measurement based only on financial and economic performance does not lead to long-term success and sustainability of organizations. Companies should monitor more their impact on society within which they operate. Proposed corporate social performance indicators in a measurable and thus manageable way express social issues.

The structural dynamics of social class.

Science.gov (United States)

Kraus, Michael W; Park, Jun Won

2017-12-01

Individual agency accounts of social class persist in society and even in psychological science despite clear evidence for the role of social structures. This article argues that social class is defined by the structural dynamics of society. Specifically, access to powerful networks, groups, and institutions, and inequalities in wealth and other economic resources shape proximal social environments that influence how individuals express their internal states and motivations. An account of social class that highlights the means by which structures shape and are shaped by individuals guides our understanding of how people move up or down in the social class hierarchy, and provides a framework for interpreting neuroscience studies, experimental paradigms, and approaches that attempt to intervene on social class disparities.

Measurability of Social Development. Reflections on the Applicability of Social Progress Indices with Reference to Brexit

Directory of Open Access Journals (Sweden)

Ivanyos János

2016-12-01

Full Text Available The question is how the global and local economic actors’ innovation-based local social and environmental objectives and results can modify the social cohesion strategies, how the disparities in economic and social development can be measured and evaluated at regional level in addition to a comparison across countries. We have seen that any one indicator in itself is not enough since it does not provide sufficient explanation for either the development disparities or their reasons. Anyway, in addition to GDP per capita, it is worth applying - and it is important to apply - such indicators as SPI and Well-Being, and various indices of social progress.

Boelen, Charles; Dharamsi, Shafik; Gibbs, Trevor

2012-01-01

There is growing interest worldwide in social accountability for medical and other health professional schools. Attempts have been made to apply the concept primarily to educational reform initiatives with limited concern towards transforming an entire institution to commit and assess its education, research and service delivery missions to better meet priority health needs in society for an efficient, equitable an sustainable health system. In this paper, we clarify the concept of social accountability in relation to responsibility and responsiveness by providing practical examples of its application; and we expand on a previously described conceptual model of social accountability (the CPU model), by further delineating the parameters composing the model and providing examples on how to translate them into meaningful indicators. The clarification of concepts of social responsibility, responsiveness and accountability and the examples provided in designing indicators may help medical schools and other health professional schools in crafting their own benchmarks to assess progress towards social accountability within the context of their particular environment.

SOCIAL MEASUREMENT OF YOUTH’S HEALTH: DESIGNING OF INDICATORS OF COMPLEX SOCIOLOGICAL RESEARCH

2017-06-01

Full Text Available Purpose. The article is devoted to solving the problem of social measurement of modern youth’s health. The subject of the analysis is the content of the concept, characteristics and indicators of the social health of young people, which enable using sociological research’ methods to measure a given status of the younger generation in contemporary Russian society. The purpose of this work is to define the theoretical and methodological foundations of the sociological analysis of the young people social health and to substantiate its main indicators in the tools of complex sociological research. Methodology of the study. The basis of the research is formed by the system approach, the complex approach, the logical-conceptual method and general scientific methods of research: comparative analysis, system analysis, construction of social indicators, modeling. Results. The social health of young people is defined through the category “status” and is considered as an integrated indicator of the social quality of the younger generation. It is substantiated that the social health of youth is a status of socio-demographic community in which it is able not only to adapt to the changing conditions of the social environment but is also ready to transform actively the surrounding reality, having the potential to resist destructive social phenomena and processes. The main indicators that allow measuring the social health of young people by sociological methods are determined: adaptability in the social environment, social activity in all spheres of public life, social orientation and significance of activity, behavior regulativity by social norms and universal values, creativity of thinking and behavior, readiness for social integration and self-development. A system of social indicators and indicators for conducting a sociological study of social health in historical memory, value orientations and everyday practices of young people has been developed.

The scope of environmental impact statements prepared during the past few years has steadily expanded to incorporate all aspects of the social as well as the natural environment, including demographic, economic, social, political, and cultural conditions. Broadly conceived, social impacts are alterations in people's living conditions that occur in conjunction with a new policy, program, or project, and that (1) are in addition to all other concurrent changes produced by other factors, and (2) are seen by those affected as significant social events. Since any social environment is constantly changing, the crucial problems in analyzing social impacts are to identify those social alterations that are a direct or indirect result of the specific action under examination, apart from all other events and changes, and to determine which of these alterations are having significant social effects on the people involved. Three features of this conception of social impacts are especially noteworthy. First, although impacts are often thought of as undesirable or detrimental in nature, they may also be desirable or beneficial. Second, although impacts are often described as caused by prior intervening innovations, in reality they always interact with their original causes in a reciprocal process, either immediately or after some time lag. Third, the purpose of social impact assessment is to enable policy makers to anticipate and plan for potential impacts before they occur, and then act to prevent or mitigate undesired impacts. A new methodology for performing social impact assessment and management studies that meet current needs by emphasizing standardized social indicators and social planning techniques is proposed. We refer to our approach as the Social Impact and Planning (SIP) method of social impact assessment

Social Performance vs. Financial Performance: CSR Disclosures as an indicator of social performance

İlker Yılmaz

2013-04-01

Full Text Available In recent decades, it is gaining more and more dominance in both academic and business life that the company exists for and has responsibilities toward a wider group of stakeholders and it must have some objectives other than profitability. To achieve sustainable development and growth, the companies must assume more duties, which is called the term “corporate social responsibility (CSR.” In the literature, it is questioned whether CSR activities benefit the company or not; whether there is any relationship exists between CSR activities and the company’s financial performance and the direction of the relationship. We aimed to explore that whether there is any effect corporate social performance (CSP on financial performance and position and vice versa. We performed content analysis through annual reports and derived a social score composed of the items included in disclosure guidelines and some criteria used in CSR ratings. We also used several financial position and financial performance indicators. In order to explore the relationship between CSP and financial indicators, we run panel data regressions. We found significant results for some of the indicators, where some of the indicators gave insignificant results. The reporting of CSR activities is in very low levels. The conscious toward CSR and sustainability must be promoted and the companies must assume more active roles. The reporting of those activities is also important.

Function and structure in social brain regions can link oxytocin-receptor genes with autistic social behavior.

Difficulties in appropriate social and communicative behaviors are the most prevalent and core symptoms of autism spectrum disorders (ASDs). Although recent intensive research has focused on the neurobiological background of these difficulties, many aspects of them were not yet elucidated. Recent studies have employed multimodal magnetic resonance imaging (MRI) indices as intermediate phenotypes of this behavioral phenotype to link candidate genes with the autistic social difficulty. As MRI indices, functional MRI (fMRI), structural MRI, and MR-spectroscopy have been examined in subjects with autism spectrum disorders. As candidate genes, this mini-review has much interest in oxytocin-receptor genes (OXTR), since recent studies have repeatedly reported their associations with normal variations in social cognition and behavior as well as with their extremes, autistic social dysfunction. Through previous increasing studies, medial prefrontal cortex, hypothalamus and amygdala have repeatedly been revealed as neural correlates of autistic social behavior by MRI multimodalities and their relationship to OXTR. For further development of this research area, this mini-review integrates recent accumulating evidence about human behavioral and neural correlates of OXTR.

Full Text Available In modern conditions of trade in the Russian Federation became the most important type of entrepreneurship. It is, in a number of objective and subjective reasons, is the most rapidly developing sector of the national economy, affecting the interests of all subjects of market relations: population, manufacturers of commercial products, government and trade. Currently in the internal trade of the Russian Federation there have been significant changes occurring under the influence of growing tensions on the international market, in the economy of our country and within the trading industry. But despite the deteriorating economic situation in the world and strained relations between the Russian Federation and its European and American partners, the latest statistics indicate the translational dynamics of retail trade turnover in the whole country, and in the Voronezh region. Retail trade turnover is among the most important indicators of economic and social development of the Voronezh region and the country as a whole. Its structure and volume characterize the level of consumption of goods population, the increase or decrease of welfare of the people. Through retail sales is a constant influence on the development of the volume and structure of production of consumer goods. This article assessed the relationship between the economic development of the Voronezh region as one of average of region of our country, its trade and standard of living of Voronezh.

Use of structured personality survey techniques to indicate operator response to stressful situations

International Nuclear Information System (INIS)

Waller, M.A.

1990-01-01

Under given circumstances, a person will tend to operate in one of four dominant orientations: (1) to perform tasks; (2) to achieve consensus; (3) to achieve understanding, or (4) to maintain structure. Historically, personality survey techniques, such as the Myers-Briggs type indicator, have been used to determine these tendencies. While these techniques can accurately reflect a person's orientation under normal social situations, under different sets of conditions, the same person may exhibit other tendencies, displaying a similar or entirely different orientation. While most do not exhibit extreme tendencies or changes of orientation, the shift in personality from normal to stressful conditions can be rather dramatic, depending on the individual. Structured personality survey techniques have been used to indicate operator response to stressful situations. These techniques have been extended to indicate the balance between orientations that the control room team has through the various levels of cognizance

To provide indicators to assess the impact on health, its social determinants and health inequalities from a social context and the recent economic recession in Spain and its autonomous regions. Based on the Spanish conceptual framework for determinants of social inequalities in health, we identified indicators sequentially from key documents, Web of Science, and organisations with official statistics. The information collected resulted in a large directory of indicators which was reviewed by an expert panel. We then selected a set of these indicators according to geographical (availability of data according to autonomous regions) and temporal (from at least 2006 to 2012) criteria. We identified 203 contextual indicators related to social determinants of health and selected 96 (47%) based on the above criteria; 16% of the identified indicators did not satisfy the geographical criteria and 35% did not satisfy the temporal criteria. At least 80% of the indicators related to dependence and healthcare services were excluded. The final selection of indicators covered all areas for social determinants of health, and 62% of these were not available on the Internet. Around 40% of the indicators were extracted from sources related to the Spanish Statistics Institute. We have provided an extensive directory of contextual indicators on social determinants of health and a database to facilitate assessment of the impact of the economic recession on health and health inequalities in Spain and its autonomous regions.

SOCIAL INDICATORS FOR EVALUATING SUSTAINABILITY OF GOAT LIVESTOCK FARMS: METHODOLOGICAL APPROACH

Directory of Open Access Journals (Sweden)

Francisco de Asís Ruiz Morales

2009-02-01

Full Text Available Currently, sustainability is an objective for any economic activity or development process. Many studies with theoretical reflections relating to the concept of sustainability exist, but few methodological contributions adequately quantify and evaluate the level of sustainability of agraricultural systems, specifically with respect to small ruminant. The level of sustainability of these systems should be estimated taking into account not only economic and environmental aspects, but also social ones. Despite its importance to the functioning of agraricultural systems, the social dimension has been little addressed, and is frequently ignored in studies of this nature. Then, the objective of this study is to carry out methodological reflections based on identification and quantification of social indicators applied to goat livestock farms. Furthermore, this study forms part of a broader comparative study on sustainable development of animal systems in Andalusia (Spain and Chiapas (Mexico, in which economic, environmental, and social indicators are used in an integrated manner. The methodology used to obtain indicators is based on the authors´ knowledge of the functioning of goat livestock systems, focus groups and opinions of experts in the field, and revision of the available bibliography. As a result of the study, we propose a group of indicators made up of several variables based on the logical-mathematical principals of different scales of measurement as well as on multicriteria analysis. The social indicators proposed refer to several themes: i multi-functionality; ii membership in professional associations; iii implication for local life; iv social well-being (quality of life, especially that related to work; and v continuity of the goats livestock activity.

Estimation of Social Exclusion Indicators from Complex Surveys: The R Package laeken

Directory of Open Access Journals (Sweden)

Andreas Alfons

2013-09-01

Full Text Available Units sampled from finite populations typically come with different inclusion proba- bilities. Together with additional preprocessing steps of the raw data, this yields unequal sampling weights of the observations. Whenever indicators are estimated from such com- plex samples, the corresponding sampling weights have to be taken into account. In addition, many indicators suffer from a strong influence of outliers, which are a common problem in real-world data. The R package laeken is an object-oriented toolkit for the estimation of indicators from complex survey samples via standard or robust methods. In particular the most widely used social exclusion and poverty indicators are imple- mented in the package. A general calibrated bootstrap method to estimate the variance of indicators for common survey designs is included as well. Furthermore, the package contains synthetically generated close-to-reality data for the European Union Statistics on Income and Living Conditions and the Structure of Earnings Survey, which are used in the code examples throughout the paper. Even though the paper is focused on showing the functionality of package laeken, it also provides a brief mathematical description of the implemented indicator methodology.

Emergence of scale-free leadership structure in social recommender systems.

2011-01-01

The study of the organization of social networks is important for the understanding of opinion formation, rumor spreading, and the emergence of trends and fashion. This paper reports empirical analysis of networks extracted from four leading sites with social functionality (Delicious, Flickr, Twitter and YouTube) and shows that they all display a scale-free leadership structure. To reproduce this feature, we propose an adaptive network model driven by social recommending. Artificial agent-based simulations of this model highlight a "good get richer" mechanism where users with broad interests and good judgments are likely to become popular leaders for the others. Simulations also indicate that the studied social recommendation mechanism can gradually improve the user experience by adapting to tastes of its users. Finally we outline implications for real online resource-sharing systems.

Online social networking sites have become increasingly popular with college students. The networks we studied are defined through ``friendships'' indicated by Facebook users from UNC, Oklahoma, Caltech, Georgetown, and Princeton. We apply the tools of network science to study the Facebook networks from these five different universities at a single point in time. We investigate each single-institution network's community structure, which we obtain through partitioning the graph using an eigenvector method. We use both graphical and quantitative tools, including pair-counting methods, which we interpret through statistical analysis and permutation tests to measure the correlations between the network communities and a set of characteristics given by each user (residence, class year, major, and high school). We also analyze the single gender subsets of these networks, and the impact of missing demographical data. Our study allows us to compare the online social networks for the five schools as well as infer differences in offline social interactions. At the schools studied, we were able to define which characteristics of the Facebook users correlate best with friendships.

Storch, Eric A; Masia-Warner, Carrie; Heidgerken, Amanda D; Fisher, Paige H; Pincus, Donna B; Liebowitz, Michael R

2006-01-01

The purpose of this study was to evaluate the factor structure of the Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA). The LSAS-CA was administered to 225 children and adolescents as a component of various clinical studies. In addition, other measures of psychopathology and impairment were administered to a subgroup of the sample. Confirmatory factor analyses of the social interaction and performance subscales for the anxiety and avoidance ratings yielded poor fit indices. Exploratory factor analysis supported a two-factor solution with a higher order factor for the LSAS-CA anxiety and avoidance ratings. Based on item content, factors were named Social and School Performance. The internal consistency of the factors was high and the convergent and divergent validity was supported vis-à-vis correlations with measures of depression and social anxiety, and clinician ratings of impairment and functioning. Findings suggest that the anxiety and avoidance ratings are best explained by a two-factor solution that measures social anxiety and avoidance in social and school performance interactions. This factor structure appears to be a reliable and valid framework for assessing childhood social phobia.

Offspring social network structure predicts fitness in families.

Social structures such as families emerge as outcomes of behavioural interactions among individuals, and can evolve over time if families with particular types of social structures tend to leave more individuals in subsequent generations. The social behaviour of interacting individuals is typically analysed as a series of multiple dyadic (pair-wise) interactions, rather than a network of interactions among multiple individuals. However, in species where parents feed dependant young, interactions within families nearly always involve more than two individuals simultaneously. Such social networks of interactions at least partly reflect conflicts of interest over the provision of costly parental investment. Consequently, variation in family network structure reflects variation in how conflicts of interest are resolved among family members. Despite its importance in understanding the evolution of emergent properties of social organization such as family life and cooperation, nothing is currently known about how selection acts on the structure of social networks. Here, we show that the social network structure of broods of begging nestling great tits Parus major predicts fitness in families. Although selection at the level of the individual favours large nestlings, selection at the level of the kin-group primarily favours families that resolve conflicts most effectively.

We investigated the reciprocal relationship between individual social capital and perceived mental and physical health in the UK. Using data from the British Household Panel Survey from 1991 to 2008, we fitted cross-lagged structural equation models that include three indicators of social capital vis. social participation, social network, and loneliness. Given that multiple measurement points (level 1) are nested within individuals (level 2), we also applied a multilevel model to allow for re...

Developing an Indicator System for Measuring the Social Sustainability of Offshore Wind Power Farms

Full Text Available Taiwan’s government has promoted investment in an offshore wind power farm, and local fishermen have protested. A social impact assessment (SIA has examined the impact of the proposed offshore wind power farm on all stakeholders. The main objective of the present study was to develop an indicator system for measuring the social sustainability of offshore wind power farms; this study also reports on the particular case of Taiwan’s offshore wind power project. This study began by defining 35 social sustainability indicators and selecting 23 representative indicators by using rough set theory. Subsequently, 14 key indicators were constructed using the social construction of technology (SCOT method. Finally, we developed a social impact index for evaluating the social sustainability of offshore wind power farms by using the analytic network process and Dempster-Shafer theory. Our social impact index yields a total score of 0.149 for Taiwan’s pilot offshore wind power project; this result indicates that the pilot project is socially sustainable. A substantial contradiction exists between the fishermen’s protest and the results of the social impact assessment. The findings can assist the government in building a coordination platform for the investors and the fishermen. Government regulation is necessary to set boundaries for fishing areas that protect both the fishermen’s and investors’ rights.

Should researchers use single indicators, best indicators, or multiple indicators in structural equation models?

Directory of Open Access Journals (Sweden)

Hayduk Leslie A

2012-10-01

Full Text Available Abstract Background Structural equation modeling developed as a statistical melding of path analysis and factor analysis that obscured a fundamental tension between a factor preference for multiple indicators and path modeling’s openness to fewer indicators. Discussion Multiple indicators hamper theory by unnecessarily restricting the number of modeled latents. Using the few best indicators – possibly even the single best indicator of each latent – encourages development of theoretically sophisticated models. Additional latent variables permit stronger statistical control of potential confounders, and encourage detailed investigation of mediating causal mechanisms. Summary We recommend the use of the few best indicators. One or two indicators are often sufficient, but three indicators may occasionally be helpful. More than three indicators are rarely warranted because additional redundant indicators provide less research benefit than single indicators of additional latent variables. Scales created from multiple indicators can introduce additional problems, and are prone to being less desirable than either single or multiple indicators.

The social structural foundations of adaptation and transformation in social-ecological systems

Directory of Open Access Journals (Sweden)

Michele L. Barnes

2017-12-01

Full Text Available Social networks are frequently cited as vital for facilitating successful adaptation and transformation in linked social-ecological systems to overcome pressing resource management challenges. Yet confusion remains over the precise nature of adaptation vs. transformation and the specific social network structures that facilitate these processes. Here, we adopt a network perspective to theorize a continuum of structural capacities in social-ecological systems that set the stage for effective adaptation and transformation. We begin by drawing on the resilience literature and the multilayered action situation to link processes of change in social-ecological systems to decision making across multiple layers of rules underpinning societal organization. We then present a framework that hypothesizes seven specific social-ecological network configurations that lay the structural foundation necessary for facilitating adaptation and transformation, given the type and magnitude of human action required. A key contribution of the framework is explicit consideration of how social networks relate to ecological structures and the particular environmental problem at hand. Of the seven configurations identified, three are linked to capacities conducive to adaptation and three to transformation, and one is hypothesized to be important for facilitating both processes. We discuss how our theoretical framework can be applied in practice by highlighting existing empirical examples from related environmental governance contexts. Further extension of our hypotheses, particularly as more data become available, can ultimately help guide the design of institutional arrangements to be more effective at dealing with change.

The Effect of Cognitive and Relational Social Capital on Structural Social Capital and Micro-Enterprise Performance

2015-10-01

Full Text Available Social capital and its dimensions are highly interrelated, and the outcome of social capital provides entrepreneurs with resources and knowledge that are not available in the first place. The objective of this study is to examine the effect of relational and cognitive social capital on structural social capital and the effect of structural social capital on the performance of micro-enterprises owned and managed by women in Peninsular Malaysia. This study uses a cross-sectional approach, and quantitative data are collected through structured interviews. It was found that cognitive social capital has a significant positive effect on structural social capital, and structural social capital has a significant positive effect on micro-enterprise performance. It was found that relational social capital has a positive but insignificant effect on structural social capital. Therefore, women entrepreneurs should emphasize on making the communication process easier and on ensuring that their business values, norms, interpretation, and meaning are shared and communicated to relevant parties to improve network ties and to build a dense network, which is essential in providing access to resources and knowledge. This, in return, is expected to improve the micro-enterprise performance in Malaysia.

The Social and Consumer Standards and Guarantees in Ukraine: the Current Structural and Dynamic Characteristics

Kolesov Oleksandr S.

2017-04-01

Full Text Available The article attempts to generalize the theoretical approaches to the social guarantees and standards as economic categories. The classification of social guarantees is provided. The dynamic parameters for development of the social and consumer standards adopted in Ukraine were considered. An evaluation of the real poverty level under the system of criteria was carried out. The inconsistency of methods for the poverty evaluation adopted by the Ministry of Social Policy of Ukraine and contradiction of its individual indicators has been indicated. The structural characteristics of the population’s income have been determined. The relevance of the existing social guarantees to their real value in today’s economic conditions have been analyzed. Tendencies of falling of the welfare level of population, resulting in a decline in the consumer demand and a narrowing of the domestic market for goods and services, have been identified. The need to take measures to stimulate small businesses, to overcome corruption, and to deregulate the economy has been indicated.

Social transmission and host developmental stage are thought to profoundly affect the structure of bacterial communities associated with honey bees and bumble bees, but these ideas have not been explored in other bee species. The halictid bees Megalopta centralis and M. genalis exhibit intrapopulation social polymorphism, which we exploit to test whether bacterial communities differ by host social structure, developmental stage, or host species. We collected social and solitary Megalopta nests and sampled bees and nest contents from all stages of host development. To survey these bacterial communities, we used 16S rRNA gene 454 pyrosequencing. We found no effect of social structure, but found differences by host species and developmental stage. Wolbachia prevalence differed between the two host species. Bacterial communities associated with different developmental stages appeared to be driven by environmentally acquired bacteria. A Lactobacillus kunkeei clade bacterium that is consistently associated with other bee species was dominant in pollen provisions and larval samples, but less abundant in mature larvae and pupae. Foraging adults appeared to often reacquire L. kunkeei clade bacteria, likely while foraging at flowers. Environmental transmission appears to be more important than social transmission for Megalopta bees at the cusp between social and solitary behavior. © 2014 Federation of European Microbiological Societies.

2014-07-01

Full Text Available The Ministry of Education in Malawi introduced a Life Skills Education programwith the intention to empower children with appropriate information and skills to deal with social and health problems affecting the nation including the fight against HIV infections. This study investigated factors affecting the teaching of the Life skills education in four primary schools in the Zomba District, Malawi. Cornbleth’s (1990 notions of the structural and social contexts and Whitaker’s (1993 identification of key role players in curriculum implementation framed the study. Findings suggest that the teaching of Life skills is constrained by a variety of social and structural contextual factors such as the poor conditions under which teachers are working; greater attention given to subjects such as Maths and Languages; the cascade model of training teachers and the short duration of training; the language in teachers guides were not accesibile to teachers; hunger and poverty of learners; lack of community support for sexual education; both teachers and learners being infected or affected by the AIDS/HIV pandemic; teachers felt it is inappropriate to teach sexual education to 9 and 10 year old learners.  These findings indicate structural and social barriers to effective life skills education within the current framework.

Why regularities in personality can be described with particular dimensions is a basic question in differential psychology. Nonhuman primates can also be characterized in terms of personality structure. Comparative approaches can help reveal phylogenetic constraints and social and ecological patterns associated with the presence or absence of specific personality dimensions. We sought to determine how different personality structures are related to interspecific variation in social style. Specifically, we examined this question in 6 different species of macaques, because macaque social style is well characterized and can be categorized on a spectrum of despotic (Grade 1) versus tolerant (Grade 4) social styles. We derived personality structures from adjectival ratings of Japanese (Macaca fuscata; Grade 1), Assamese (M. assamensis; Grade 2), Barbary (M. sylvanus; Grade 3), Tonkean (M. tonkeana; Grade 4), and crested (M. nigra; Grade 4) macaques and compared these species with rhesus macaques (M. mulatta; Grade 1) whose personality was previously characterized. Using a nonparametric method, fuzzy set analysis, to identify commonalities in personality dimensions across species, we found that all but 1 species exhibited consistently defined Friendliness and Openness dimensions, but that similarities in personality dimensions capturing aggression and social competence reflect similarities in social styles. These findings suggest that social and phylogenetic relationships contribute to the origin, maintenance, and diversification of personality. (c) 2015 APA, all rights reserved.

Ammenwerth, Elske; Hackl, Werner O

2017-01-01

Learning as a constructive process works best in interaction with other learners. Support of social interaction processes is a particular challenge within online learning settings due to the spatial and temporal distribution of participants. It should thus be carefully monitored. We present structural network analysis and related indicators to analyse and visualize interaction patterns of participants in online learning settings. We validate this approach in two online courses and show how the visualization helps to monitor interaction and to identify activity profiles of learners. Structural network analysis is a feasible approach for an analysis of the intensity and direction of interaction in online learning settings.

Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p591   Subjective social status comprises the perception of individuals about their social status. The aim of this study was to investigate the relationship between subjective social status and sociodemographic indicators (age, educational level, marital status and economic level in athletes from Santa Catharina. A total of 593 athletes of both sexes and mean age of 21.18 (± 5.58 years, 371 men, randomly selected, practitioners of individual and collective sport modalities, federated in clubs in the western region of Santa Catarina participated in the study. Social status perception was assessed using the MacArthur scale version for young people adapted to the sports context. For the association between perceived status and sociodemographic indicators, the Chi-square and Multinomial Logistic Regression tests were used, stratified by gender and adjusted for age variables, educational level, marital status and socioeconomic status. Dissatisfaction with status was found in 85% of the sample. Moreover, 46.9% of participants perceived themselves with low family status and 46% perceived themselves with intermediate status in their clubs. The association between groups showed statistically significant differences according to sex, age, educational level and marital status. The association between sociodemographic variables and status according to sex indicated that younger men, with less education, and single were more likely to be dissatisfied with their status. There is need for greater attention by health professionals regarding younger male athletes, with lower education and single regarding their status perception.

Although social exchange theory has become one of the most oft-evoked theories in industrial and organizational psychology, there remains no consensus about how to measure its key mechanism: social exchange relationships (Blau, 1964). Drawing on Cropanzano and Byrne's (2000) review of contemporary social exchange theorizing, we examined the content validity of perceived support, exchange quality, affective commitment, trust, and psychological contract fulfillment as indicators of social exchange relationships. We used Hinkin and Tracey's (1999) quantitative approach to content validation, which asks participants to rate the correspondence between scale items and definitions of intended (and unintended) constructs. Our results revealed that some of the most frequently utilized indicators of social exchange relationships--perceived support and exchange quality--were significantly less content valid than rarely used options like affect-based trust. Our results also revealed that 2 direct measures--Bernerth, Armenakis, Feild, Giles, and Walker's (2007) scale and a scale created for this study--were content valid. We discuss the implications of these results for future applications of social exchange theory.

Methods for extracting climate indicator data from social media.

Fuka, M. Z.; Fuka, D. R.

This paper shows how we've used the R software suite to extract climate indicator data from Twitter. In the course of this research we've collected extensive data sets of unsolicited observations ("tweets") for hundreds of climate-related phenological, biological, epidemiological and meteorological effects. R has proved itself in our work as a useful tool for manipulating those large data sets. Our experience from this effort has yielded a variety of insights on using R to extract geophysics-specific information from publicly accessible social media sources. We illustrate our methodology by mapping tweeted US armadillo sightings to explore the impact of climate variability on the extent of the animal's range. This example usefully demonstrates R's technical capabilities in collecting, time-stamping, geolocating, analyzing, visualizing and otherwise processing climate-related data derived from unsolicited social media postings. We also "mash-up" the data sets with those acquired by more traditional means, for example, temperature and precipitation data across the armadillo's US range. Our data-handling practice is extendable to social sharing services other than Twitter, providing the environmental modeling community an opportunity to access largely untapped resources of non-traditional climate indicator data to better understand the effects of climate change at local, regional and global scales.

Structured Play Therapy Groups for Preschoolers: facilitating the emergence of social competence.

Science.gov (United States)

Stone, Susan; Stark, Martha

2013-01-01

Over the years, we have developed a working model of Structured Play Therapy Groups for Preschoolers, an innovative treatment approach designed to address the needs of young children ages 3 to 5 struggling to adjust to the social demands of their preschool classrooms. These short-term therapy groups facilitate development of the young child's social competence and capacity to participate effectively in a classroom environment. Although the literature on therapy groups for children suggests that preschoolers are not yet evolved enough developmentally to engage actively in a group process, our experience indicates otherwise. The model of treatment presented here will therefore challenge that contention with the claim that not only can preschoolers participate in a structured therapy group of peers but they can, by virtue of that very participation, benefit in ways that will prepare them (as they transition from preschool to kindergarten) for the ever-increasing demands of their ever-expanding social milieus.

Despite the expanding use of social media, little has been published about its appropriate role in health promotion, and even less has been written about evaluation. The purpose of this article is threefold: (a) outline purposes for social media in health promotion, (b) identify potential key performance indicators associated with these purposes, and (c) propose evaluation metrics for social media related to the key performance indicators. Process evaluation is presented in this article as an overarching evaluation strategy for social media.

Social Wealth Economic Indicators for a Caring Economy

Directory of Open Access Journals (Sweden)

Indradeep Ghosh

2015-06-01

Full Text Available This essay introduces the reader to an entirely new set of measures that are urgently needed by policymakers and business leaders to foster personal, business, and national economic success. Social Wealth Economic Indicators are measures suggested by a partnership model of society, and they inform us that care work matters tremendously but is grossly undervalued. In our contemporary knowledge-service economy, the essential ingredient for social and economic progress is high-quality human capital, and the way to build such human capital is to support the work of caring and caregiving, traditionally considered “women’s work.” The data presented in this essay clearly show that early childhood care and education, family-friendly workplace practices, and the status of women are key determinants of economic success. But they are also necessary for healthy, creative, and cohesive societies in which members work in partnership with each other and with the natural environment to improve living conditions for all. This is the true meaning of social wealth.

Defining acceptable levels for ecological indicators: an approach for considering social values.

Smyth, Robyn L; Watzin, Mary C; Manning, Robert E

2007-03-01

Ecological indicators can facilitate an adaptive management approach, but only if acceptable levels for those indicators have been defined so that the data collected can be interpreted. Because acceptable levels are an expression of the desired state of the ecosystem, the process of establishing acceptable levels should incorporate not just ecological understanding but also societal values. The goal of this research was to explore an approach for defining acceptable levels of ecological indicators that explicitly considers social perspectives and values. We used a set of eight indicators that were related to issues of concern in the Lake Champlain Basin. Our approach was based on normative theory. Using a stakeholder survey, we measured respondent normative evaluations of varying levels of our indicators. Aggregated social norm curves were used to determine the level at which indicator values shifted from acceptable to unacceptable conditions. For seven of the eight indicators, clear preferences were interpretable from these norm curves. For example, closures of public beaches because of bacterial contamination and days of intense algae bloom went from acceptable to unacceptable at 7-10 days in a summer season. Survey respondents also indicated that the number of fish caught from Lake Champlain that could be safely consumed each month was unacceptably low and the number of streams draining into the lake that were impaired by storm water was unacceptably high. If indicators that translate ecological conditions into social consequences are carefully selected, we believe the normative approach has considerable merit for defining acceptable levels of valued ecological system components.

Social indicators of sustainable building; Soziale Indikatoren des nachhaltigen Bauens

Energy Technology Data Exchange (ETDEWEB)

Greiff, Rainer

2012-06-15

As a result of the UN Conference on Environment and Development (UNCED) in 1992 in Rio de Janeiro (''Earth Summit'') the participating nations agreed upon principles of sus-tainable development and objectives for sustainable development - the so called ''Agenda 21'' - to be pursued by national sustainability strategies and be monitored by systems of appropriate relative indicators. The participants shared the awareness that ecological objectives aiming at the global preservation of the natural resources can be achieved only if sustainable economic and social developments are considered together. Unlike the ecological demands of protection of climate and resources, for which evidence can be provided by natural sciences and that can be substantiated by figures, a common under-standing of the social dimension of sustainability has not yet emerged. The same is true for the concept of ''sustainable building''. In the guideline ''Sustainable Building'' published by the Federal Ministry of Transport, Building and Housing in 2001, essential instructions regarding the implementation of ob-jectives for ecological construction were compiled for use in practice. This guideline is now to be supplemented by objectives of social sustainability. As a basis for common understanding a definition of the social aspects of sustainable building will be brought forward, which is expected to be broadly acknowledged. Furthermore indicators for the social dimension of sustainability were to be developed so that the observance of socio-cultural aspects of sustainability may be operationalised for new construction as well as refurbishment.

On Topological Indices of Certain Dendrimer Structures

Aslam, Adnan; Bashir, Yasir; Ahmad, Safyan; Gao, Wei

2017-05-01

A topological index can be considered as transformation of chemical structure in to real number. In QSAR/QSPR study, physicochemical properties and topological indices such as Randić, Zagreb, atom-bond connectivity ABC, and geometric-arithmetic GA index are used to predict the bioactivity of chemical compounds. Dendrimers are highly branched, star-shaped macromolecules with nanometer-scale dimensions. Dendrimers are defined by three components: a central core, an interior dendritic structure (the branches), and an exterior surface with functional surface groups. In this paper we determine generalised Randić, general Zagreb, general sum-connectivity indices of poly(propyl) ether imine, porphyrin, and zinc-Porphyrin dendrimers. We also compute ABC and GA indices of these families of dendrimers.

Although homelessness is inherently associated with social exclusion, homeless individuals are rarely included in conventional studies on social exclusion. Use of longitudinal survey data from a cohort study on homeless people in four major Dutch cities ( n  = 378) allowed to examine: changes in indicators of social exclusion among homeless people over a 2.5-year period after reporting to the social relief system, and associations between changes in indicators of social exclusion and changes in psychological distress. Multinomial logistic regression analysis was applied to investigate the associations between changes in indicators of social exclusion and changes in psychological distress. Improvements were found in various indicators of social exclusion, whereas financial debts showed no significant improvement. Changes in unmet care needs, health insurance, social support from family and relatedness to others were related to changes in psychological distress. This study demonstrated improvements in various indicators of social exclusion among homeless people over a period of 2.5 years, and sheds light on the concept of social exclusion in relation to homelessness.

To distinguish normative fears from problematic fears and phobias. We investigated 2,512 children and adolescents from a large community school-based study, the High Risk Study for Psychiatric Disorders. Parent reports of 18 fears and psychiatric diagnosis were investigated. We used two analytical approaches: confirmatory factor analysis (CFA)/item response theory (IRT) and nonparametric receiver operating characteristic (ROC) curve. According to IRT and ROC analyses, social fears are more likely to indicate problems and phobias than specific fears. Most specific fears were normative when mild; all specific fears indicate problems when pervasive. In addition, the situational fear of toilets and people who look unusual were highly indicative of specific phobia. Among social fears, those not restricted to performance and fear of writing in front of others indicate problems when mild. All social fears indicate problems and are highly indicative of social phobia when pervasive. These preliminary findings provide guidance for clinicians and researchers to determine the boundaries that separate normative fears from problem indicators in children and adolescents, and indicate a differential severity threshold for specific and social fears.

Can competing diversity indices inform us about why ethnic diversity erodes social cohesion? A test of five diversity indices in Germany.

Science.gov (United States)

Schaeffer, Merlin

2013-05-01

An ever-growing number of studies investigates the relation between ethnic diversity and social cohesion, but these studies have produced mixed results. In cross-national research, some scholars have recently started to investigate more refined and informative indices of ethnic diversity than the commonly used Hirschman-Herfindahl Index. These refined indices allow to test competing theoretical explanations of why ethnic diversity is associated with declines in social cohesion. This study assesses the applicability of this approach for sub-national analyses. Generally, the results confirm a negative association between social cohesion and ethnic diversity. However, the competing indices are empirically indistinguishable and thus insufficient to test different theories against one another. Follow-up simulations suggest the general conclusion that the competing indices are meaningful operationalizations only if a sample includes: (1) contextual units with small and contextual units with large minority shares, as well as (2) contextual units with diverse and contextual units with polarized ethnic compositions. The results are thus instructive to all researchers who wish to apply different diversity indices and thereby test competing theories. Copyright © 2013 Elsevier Inc. All rights reserved.

Entropy model of dissipative structure on corporate social responsibility

Science.gov (United States)

Li, Zuozhi; Jiang, Jie

2017-06-01

Enterprise is prompted to fulfill the social responsibility requirement by the internal and external environment. In this complex system, some studies suggest that firms have an orderly or chaotic entropy exchange behavior. Based on the theory of dissipative structure, this paper constructs the entropy index system of corporate social responsibility(CSR) and explores the dissipative structure of CSR through Brusselator model criterion. Picking up listed companies of the equipment manufacturing, the research shows that CSR has positive incentive to negative entropy and promotes the stability of dissipative structure. In short, the dissipative structure of CSR has a positive impact on the interests of stakeholders and corporate social images.

Corporate social responsibility in the mining industry: Criteria and indicators

International Nuclear Information System (INIS)

Vintro, Carla; Comajuncosa, Josep

2010-01-01

Corporate Social Responsibility (CSR) includes economic, social and environmental aspects, and it has particular significance in mining. This paper explores the subject of CSR in the mining industry and the main synergies between CSR and environmental, safety and quality management systems, whose adoption has increased during recent decades. It proposes the establishment of a set of criteria for sustainability, ethics and human capital (to be called CSR criteria). Whilst various international bodies have proposed CSR guides and indicators (commonly used as references for Stock Market investments), there is evidence that the size of the company can act as a moderator factor to the adoption of those systems. The paper offers an easy-to-use CSR performance chart (composed of 31 indicators and a global index), intended as an internal measure for companies of CSR continuous improvement.

To study the association between structural and cognitive aspects of social capital and depression among older adults in two Nordic regions. Data were retrieved from a postal survey targeting older adults aged 65, 70, 75 and 80 years (N=6 838, response rate=64%) residing in the Västerbotten region (Sweden), and the Österbotten region (Finland) in 2010. The associations between structural (measured by frequency of social contact with friends and neighbours) and cognitive (measured by experienced trust in friends and neighbours) aspects of social capital and depression (measured by Geriatric Depression Scale, GDS-4) were tested by logistic regression analyses. Both low structural and cognitive social capital as defined in the study showed statistically significant associations with depression in older adults. Only experienced trust in neighbours failed to show significant association with depression. In addition, being single and being 80 years of age indicated a higher risk of depression as defined by GDS-4. The findings underline the connection between adequate levels of both structural and cognitive individual social capital and mental health in later life. They also suggest that the connection differs depending on various network types; the cognitive aspect of relationships between friends was connected to depression, while the connection was not found for neighbours. Further, the oldest age group in the sample (80 years of age) is pointed out as a population especially vulnerable for depression that should not be overlooked in mental health promotion and depression prevention.

Murder by structure: dominance relations and the social structure of gang homicide.

Papachristos, Andrew V

2009-07-01

Most sociological theories consider murder an outcome of the differential distribution of individual, neighborhood, or social characteristics. And while such studies explain variation in aggregate homicide rates, they do not explain the social order of murder, that is, who kills whom, when, where, and for what reason. This article argues that gang murder is best understood not by searching for its individual determinants but by examining the social networks of action and reaction that create it. In short, the social structure of gang murder is defined by the manner in which social networks are constructed and by people's placement in them. The author uses a network approach and incident-level homicide records to recreate and analyze the structure of gang murders in Chicago. Findings demonstrate that individual murders between gangs create an institutionalized network of group conflict, net of any individual's participation or motive. Within this network, murders spread through an epidemic-like process of social contagion as gangs evaluate the highly visible actions of others in their local networks and negotiate dominance considerations that arise during violent incidents.

Pain is a subjective emotional experience that is influenced by psychosociological factors such as social skills, which are defined as problem-solving abilities in social interactions. This study aimed to reveal the relationships among pain, social skills, and other psychosociological factors by using structural equation modeling. A total of 101 healthy volunteers (41 men and 60 women; mean age: 36.6±12.7 years) participated in this study. To evoke participants' sense of inner pain, we showed them images of painful scenes on a PC screen and asked them to evaluate the pain intensity by using the visual analog scale (VAS). We examined the correlation between social skills and VAS, constructed a hypothetical model based on results from previous studies and the current correlational analysis results, and verified the model's fit using structural equation modeling. We found significant positive correlations between VAS and total social skills values, as well as between VAS and the "start of relationships" subscales. Structural equation modeling revealed that the values for "start of relationships" had a direct effect on VAS values (path coefficient =0.32, p social support. The results indicated that extroverted people are more sensitive to inner pain and tend to get more social support and maintain a better psychological condition.

Full Text Available This study aims to analyze the factorial structure of the newly-created Cuestionario de Autoconcepto Social - AUSO (from here on the Social Self-concept Questionnaire, or AUSO, which consists of two scales measuring social responsibility and social competence. The theoretical proposal which posits that social self-concept is the result of the combination of two basic self-perceptions: competence in social relations and response to the demands of social functioning, is based on a review of human social development theories and previous attempts to measure social self-concept. Participants were 818 students aged between 17 and 52. The results obtained though confirmatory factor analyses support the hypothesis of a structure made up of two correlated factors. In addition to providing a new measurement instrument with appropriate psychometric characteristics and valid criteria that justify its use in both applied practice and research, this study also enhances our understanding of the internal nature of the social domain of self-concept.

Social structure affects mating competition in a damselfish

The strength of mating competition and sexual selection varies over space and time in many animals. Such variation is typically driven by ecological and demographic factors, including adult sex ratio and consequent availability of mates. The spatial scale at which demographic factors affect mating competition and sexual selection may vary but is not often investigated. Here, we analyse variation in size and sex ratio of social groups, and how group structure affects mating competition, in the site-attached damselfish Chrysiptera cyanea. Site-attached reef fishes are known to show extensive intraspecific variation in social structure. Previous work has focused on species for which the size and dynamics of social groups are constrained by habitat, whereas species with group structure unconstrained by habitat have received little attention. Chrysiptera cyanea is such a species, with individuals occurring in spatial clusters that varied widely in size and sex ratio. Typically, only one male defended a nest in multi-male groups. Nest-holding males were frequently visited by mate-searching females, with more visits in groups with more females, suggesting that courtship and mating mostly occur within groups and that male mating success depends on the number of females in the group. Male-male aggression was frequent in multi-male groups but absent in single-male groups. These findings demonstrate that groups are distinct social units. In consequence, the dynamics of mating and reproduction are mainly a result of group structure, largely unaffected short term by overall population demography which would be important in open social systems. Future studies of the C. cyanea model system should analyse longer-term dynamics, including how groups are formed, how they vary in relation to density and time of season and how social structure affects sexual selection.

Additional Indicators to Promote Social Sustainability within Government Programs: Equity and Efficiency

Full Text Available Social programs are crucial to reduce poverty and inequity in developing countries. The operation of social programs, however, cannot be improved with traditional engineering tools since these tools are designed to maximize profits: in social programs maximizing profits is not the objective, social sustainability is. Field research was conducted and it was found that the operation of social programs is considered more socially sustainable if it meets two criteria: Efficiency and Equity; in other words, if the program can help more people who need it the most. This paper proposes a methodology centered in the development of mathematical formulas for the concepts of Efficiency and Equity, so that, by being able to measure them, government programs operation can be enhanced with engineering tools. The methodology is illustrated with a case study, a subsidized milk distribution program in Mexico, called Liconsa. Once the formulas were developed and used in a simulation model for Liconsa, different policies were tested and their results regarding Efficiency and Equity were compared. Results showed the best policies for Liconsa are the balanced ones: where help is increased for beneficiaries, while cost reduction commitments are obtained. In the discussion it is argued how the developed Equity and Efficiency indicators help to understand the tradeoffs between the objectives in opposition: instead of analyzing dozens of indicators, some of them improving and others worsening, the two formulas allow to capture all effects into two objectives and evaluate decisions based on their integral impact. Conclusions show that the mathematical definition of Equity and Efficiency supports better and more informed decision making towards improving the social sustainability of the programs operation. The mathematical definition of Equity and Efficiency and its use in engineering models helps balance the opposing objectives of social programs operation and promotes

Nonverbal Synchrony in Social Interactions of Patients with Schizophrenia Indicates Socio-Communicative Deficits.

Directory of Open Access Journals (Sweden)

Zeno Kupper

Full Text Available Disordered interpersonal communication can be a serious problem in schizophrenia. Recent advances in computer-based measures allow reliable and objective quantification of nonverbal behavior. Research using these novel measures has shown that objective amounts of body and head movement in patients with schizophrenia during social interactions are closely related to the symptom profiles of these patients. In addition to and above mere amounts of movement, the degree of synchrony, or imitation, between patients and normal interactants may be indicative of core deficits underlying various problems in domains related to interpersonal communication, such as symptoms, social competence, and social functioning.Nonverbal synchrony was assessed objectively using Motion Energy Analysis (MEA in 378 brief, videotaped role-play scenes involving 27 stabilized outpatients diagnosed with paranoid-type schizophrenia.Low nonverbal synchrony was indicative of symptoms, low social competence, impaired social functioning, and low self-evaluation of competence. These relationships remained largely significant when correcting for the amounts of patients' movement. When patients showed reduced imitation of their interactants' movements, negative symptoms were likely to be prominent. Conversely, positive symptoms were more prominent in patients when their interaction partners' imitation of their movements was reduced.Nonverbal synchrony can be an objective and sensitive indicator of the severity of patients' problems. Furthermore, quantitative analysis of nonverbal synchrony may provide novel insights into specific relationships between symptoms, cognition, and core communicative problems in schizophrenia.

Environmental and social impact quantitative assessment is an essential tool for the correct location of economic activities within the territory. The main problem of impact quantification lies in establishing the appropriateness of the instruments (indicators) utilised, such that their level of objectivity is the highest possible. To improve the quality of this kind of studies, the present contribution discusses this problematic question and its consequences and proposes a methodology for the validation of indicators. Finally, the methodology proposed is subjected to an observational and experimental test to demonstrate the feasibility of the proposal. The test is performed on four indicators, which are designed ad hoc to assess alternatives in industrial facility location problems where the decision-making process has to be supported by an environmental and social impact assessment

Social insects rank among the most invasive of terrestrial species. The success of invasive social insects stems, in part, from the flexibility derived from their social behaviors. We used genetic markers to investigate if the social system of the invasive wasp, Vespula pensylvanica, differed in its introduced and native habitats in order to better understand variation in social phenotype in invasive social species. We found that (1) nestmate workers showed lower levels of relatedness in introduced populations than native populations, (2) introduced colonies contained workers produced by multiple queens whereas native colonies contained workers produced by only a single queen, (3) queen mate number did not differ significantly between introduced and native colonies, and (4) workers from introduced colonies were frequently produced by queens that originated from foreign nests. Thus, overall, native and introduced colonies differed substantially in social phenotype because introduced colonies more frequently contained workers produced by multiple, foreign queens. In addition, the similarity in levels of genetic variation in introduced and native habitats, as well as observed variation in colony social phenotype in native populations, suggest that colony structure in invasive populations may be partially associated with social plasticity. Overall, the differences in social structure observed in invasive V. pensylvanica parallel those in other, distantly related invasive social insects, suggesting that insect societies often develop similar social phenotypes upon introduction into new habitats.

SOCIAL POLICIES AND STRUCTURAL REFORMS IN EUROPE

2006-12-01

Full Text Available This paper considers the social and structural policies in contemporary Europe. The presentation is organized in four sections. First, we discuss the emerging Europe, the new unity based on democracy and the market economy, the special European Union formula, and comparisons with America. Second, we analyze the dynamics of the European economy, the convergence process, the gaps between United States in productivity and standard of living, competitiveness issues, and the emergence of a new European economy and new European policy mix.Third, we consider European social conditions, the stationary and aging population, Europe’s low employment rate and permanently high unemployment. European economic growth could draw on two major sources: the labor reserves and reforms in factor, product and service markets. In a monetary union, advanced industrial relations should promote labor mobility and salary flexibility. The social security systems permit the redistribution and cohesion which defines the European model.Fourth, for the new Europe, the structural reform strategy is the way forward for the challenge of European economic policy and social policy: more and better jobs thanks to sustainable growth in a dynamic and competitive knowledge-based economy, favoring greater social cohesion.

CONSUMPTION AS A SOCIAL STATUS SYMBOL IN STRUCTURALISM

N. D. Naydenov

2014-10-01

Full Text Available The article looks at the basic theoretical concepts of the political economy of the sign (structuralism, postmodernity and their development in the theory of power based on the work by J. Baudrillard ‘For a Critique of the Political Economy of the Sign’. The study is focused on consumption as the person’s social status symbol, it compares and contrasts basic concepts of structuralism and neo-liberalism.According to structuralism social structure is reproduced through the reproduction of objects/signs. It is important that not only things or money but mathematical formulas, linguistic constructions and people can act as signs. Structuralism views consumption as a person’s social status symbol. Respectively, exchange is viewed as the exchange of symbols.  The society needs the diversity of signs and manipulating the signs is one of the modern society’s illnesses.Liberalism is a social movement, which confronts the person’s enslavement by communal ties and limitations within the limits of property and in the aspects where the individual is helpless in front of the society. Neoliberalism proclaims the liberal model of an individual, who is primarily concerned with their belonging to their society and the struggle between the signs is significant. Assigning a certain value to the symbol is typical both for structuralism and neo-modernism.The authors find it necessary to raise the symbolic diversity of the Russian society trough increasing the forms of consumption. At the same time we should not forget that the society is based on material production.

2015-12-01

Chinese immigrants tend to rely on family and close community for support given their vulnerable societal position. Yet stigma, especially from structural and familial sources, may have a particularly harmful impact upon Chinese immigrants with psychosis. Using a descriptive analysis based upon grounded theory, we examined stigma experiences of 50 Chinese immigrant consumers with psychosis, paying particular attention to frequency, sources, and themes of social and structural stigma. Although past research indicates that family is a recipient of stigma, we found instead that family members were common perpetuators of social forms of stigma. We also found that perceptions of work deficit underlie many forms of stigma, suggesting this is "what matters most" in this community. Lack of financial resources and language barriers comprised most frequent forms of structural stigma. Anti-stigma efforts should aim to improve consumer's actual and perceived employability to target what is most meaningful in Chinese immigrant communities.

Competing Structure, Competing Views: The Role of Formal and Informal Social Structures in Shaping Stakeholder Perceptions

Directory of Open Access Journals (Sweden)

Christina Prell

2010-12-01

Full Text Available What is social structure, and how does it influence the views and behaviors of land managers? In this paper, we unpack the term "social structure" in the context of current research on institutions, social networks, and their role(s in resource management. We identify two different kinds of structure, formal and informal, and explore how these link to views of land management and management practice. Formal structures refer to intentionally designed organizations that arise out of larger institutional arrangements; informal ones refer to social networks, based on the communication contacts individuals possess. Our findings show significant correlations between respondents' views regarding land management and their social networks; it is these informal structures that have greater influence on what stakeholders perceive. These findings suggest that stakeholders are less influenced by their particular organizational affiliation or category (e.g., "conservationist" versus "farmer", and more by whom they speak with on a regular basis regarding land management. We conclude with a discussion on the practical implications for resource managers wishing to "design" participatory management, arguing that, if "diversity" is the goal in designing such participatory processes, then diversity needs to translate beyond stakeholder categories to include consideration for the personal, social networks surrounding stakeholders.

Perceptions of Social Mobility: Development of a New Psychosocial Indicator Associated with Adolescent Risk Behaviors

Directory of Open Access Journals (Sweden)

Miranda Lucia Ritterman Weintraub

2015-04-01

Full Text Available Social class gradients have been explored in adults and children, but not extensively during adolescence. The first objective of this study was to examine the association between adolescent risk behaviors and a new indicator of adolescent relative social position, adolescent perceived social mobility. Second, it investigated potential underlying demographic, socioeconomic and psychosocial determinants of this indicator. Data were taken from the 2004 urban adolescent module of Oportunidades, a cross-sectional study of Mexican adolescents living in poverty. Perceived social mobility was calculated for each subject by taking the difference between their rankings on two 10-rung ladder scales that measured (1 projected future social status and (2 current subjective social status within Mexican society. Adolescents with higher perceived social mobility were significantly less likely to report alcohol consumption, drinking with repercussions, compensated sex, police detainment, physical fighting, consumption of junk food or soda, or watching ≥ 4 hours of television during the last viewing. They were significantly more likely to report exercising during the past week and using a condom during last sexual intercourse. These associations remained significant with the inclusion of covariates, including parental education and household expenditures. Multiple logistic regression analyses show higher perceived social mobility to be associated with staying in school longer and having higher perceived control. The present study provides evidence for the usefulness of perceived social mobility as an indicator for understanding the social gradient in health during adolescence. This research suggests the possibility of implementing policies and interventions that provide adolescents with real reasons to be hopeful about their trajectories.

Globalization, financial capitalism, and corporate social responsibility: Structural tensions

2014-12-01

Full Text Available Globalization and financial capitalism keep a synergy in a global context whose problems such as environmental degradation, social inequity, economic crises and corruption are intensified. Corporate Social Responsibility emerges as a mechanism that seeks to mitigate some of these problems, although its effectiveness and impact today are challenged. The system which globalization, financial capitalism and social responsibility are a part of, is currently facing a number of structural tensions that contribute to the analysis, understanding and solving of the mentioned problems. This paper identifies and analyzes four of the aforementioned structural tensions.

Traud, Amanda L.; Mucha, Peter J.; Porter, Mason A.

2012-08-01

We study the social structure of Facebook “friendship” networks at one hundred American colleges and universities at a single point in time, and we examine the roles of user attributes-gender, class year, major, high school, and residence-at these institutions. We investigate the influence of common attributes at the dyad level in terms of assortativity coefficients and regression models. We then examine larger-scale groupings by detecting communities algorithmically and comparing them to network partitions based on user characteristics. We thereby examine the relative importance of different characteristics at different institutions, finding for example that common high school is more important to the social organization of large institutions and that the importance of common major varies significantly between institutions. Our calculations illustrate how microscopic and macroscopic perspectives give complementary insights on the social organization at universities and suggest future studies to investigate such phenomena further.

Structural and intermediary determinants of social inequalities in the mental well-being of European workers: a relational approach.

2014-09-09

The objective of this study is to examine social inequalities in employee mental well-being, using relational social class indicators. Relational social class indicators are based on theoretical insights about the mechanisms generating social (health) inequalities. Additionally, it is examined whether the psychosocial work environment and employment quality act as intermediary determinants of social class inequalities in mental well-being, simultaneously testing the mediation (differential exposure) and moderation (differential vulnerability) hypotheses. Data from the European Social Survey Round 2 (2004/5) and Round 5 (2010) were analysed. Mental well-being was assessed by the WHO Well-being Index. The measure for social class was inspired by E.O. Wright's class scheme. Three-level linear multilevel modelling was used to account for clustering of employees within research years and countries. We found social class inequalities in mental well-being in the European working population for both men and women. Compared to unskilled workers, managers reported the best mental well-being, while supervisors held an intermediary position. As regards the mediation hypothesis, an unfavourable psychosocial work environment and low-quality employment conditions mediated the relation between social class and poor mental well-being in both men and women. However, low quality of employment relations only mediated the "social class-mental well-being" association in the male sample. As regards the moderation hypothesis, modification effects were seen for the psychosocial work environment and employment conditions in both men and women. Relational indicators of social class are related to mental well-being in European employees. Relational accounts of social class are complementary to stratification indicators in social epidemiology. From a policy perspective, better employee mental well-being and less social class inequality could be achieved through initiatives addressing the

Social structure predicts genital morphology in African mole-rats.

Full Text Available African mole-rats (Bathyergidae, Rodentia exhibit a wide range of social structures, from solitary to eusocial. We previously found a lack of sex differences in the external genitalia and morphology of the perineal muscles associated with the phallus in the eusocial naked mole-rat. This was quite surprising, as the external genitalia and perineal muscles are sexually dimorphic in all other mammals examined. We hypothesized that the lack of sex differences in naked mole-rats might be related to their unusual social structure.We compared the genitalia and perineal muscles in three African mole-rat species: the naked mole-rat, the solitary silvery mole-rat, and the Damaraland mole-rat, a species considered to be eusocial, but with less reproductive skew than naked mole-rats. Our findings support a relationship between social structure, mating system, and sexual differentiation. Naked mole-rats lack sex differences in genitalia and perineal morphology, silvery mole-rats exhibit sex differences, and Damaraland mole-rats are intermediate.The lack of sex differences in naked mole-rats is not an attribute of all African mole-rats, but appears to have evolved in relation to their unusual social structure and reproductive biology.

Gallego Carrera, Diana; Mack, Alexander

2010-01-01

Sustainability assessment of energy technologies oftentimes fails to account for social repercussions and long-term negative effects and benefits of energy systems. As part of the NEEDS project, an expert-based set of social indicators was developed and verified by the European stakeholders with the objective of contributing in the development of social indicators for the assessment of societal effects of energy systems. For this purpose, scientific experts from four sample countries France, Germany, Italy and Switzerland were interviewed to assess 16 different energy systems on a specific stakeholder reviewed indicator set. The indicator set covers the four main criteria: 'security and reliability of energy provision; 'political stability and legitimacy'; 'social and individual risks' and 'quality of life'. This article will review the process of indicator development and assessment and highlight results for today's most prominent and future energy technologies and some likely to make an impact in the future. Expert judgments varied considerably between countries and energy systems, with the exception of renewable technologies, which were overall positively assessed on almost all evaluation criteria.

Information content and acoustic structure of male African elephant social rumbles.

Science.gov (United States)

Stoeger, Angela S; Baotic, Anton

2016-06-08

Until recently, the prevailing theory about male African elephants (Loxodonta africana) was that, once adult and sexually mature, males are solitary and targeted only at finding estrous females. While this is true during the state of 'musth' (a condition characterized by aggressive behavior and elevated androgen levels), 'non-musth' males exhibit a social system seemingly based on companionship, dominance and established hierarchies. Research on elephant vocal communication has so far focused on females, and very little is known about the acoustic structure and the information content of male vocalizations. Using the source and filter theory approach, we analyzed social rumbles of 10 male African elephants. Our results reveal that male rumbles encode information about individuality and maturity (age and size), with formant frequencies and absolute fundamental frequency values having the most informative power. This first comprehensive study on male elephant vocalizations gives important indications on their potential functional relevance for male-male and male-female communication. Our results suggest that, similar to the highly social females, future research on male elephant vocal behavior will reveal a complex communication system in which social knowledge, companionship, hierarchy, reproductive competition and the need to communicate over long distances play key roles.

Between Bandura and Giddens: Structuration Theory in Social Psychological Research?

Directory of Open Access Journals (Sweden)

Seth Oppong

2014-10-01

Full Text Available In any social analysis, one can attribute observed behavioural outcomes to actions and inactions of people (agents or to the presence or absence of certain structures or systems. The dualism of agent and structure is resolved through the concept of duality as proposed by Anthony Giddens in his structuration theory (ST. Though ST has been applied in other disciplines, it is either less known or applied in psychology. This paper sought to examine ST as a framework for understanding the interdependent relationship between structure and agents in the light of offering explanatory framework in social science research or policy formulation. It concluded with an integrated model comprising elements of both Bandura’s social-cognitive theory and Giddens’ ST.

Who Hires Social Workers? Structural and Contextual Determinants of Social Service Staffing in Nursing Homes.

Although nurse staffing has been extensively studied within nursing homes (NHs), social services has received less attention. The study describes how social service departments are organized in NHs and examines the structural characteristics of NHs and other macro-focused contextual factors that explain differences in social service staffing patterns using longitudinal national data (Certification and Survey Provider Enhanced Reports, 2009-2012). NHs have three patterns of staffing for social services, using qualified social workers (QSWs); paraprofessional social service staff; and interprofessional teams, consisting of both QSWs and paraprofessionals. Although most NHs employ a QSW (89 percent), nearly half provide social services through interprofessional teams, and 11 percent rely exclusively on paraprofessionals. Along with state and federal regulations that depend on facility size, other contextual and structural factors within NHs also influence staffing. NHs most likely to hire QSWs are large facilities in urban areas within a health care complex, owned by nonprofit organizations, with more payer mixes associated with more profitable reimbursement. QSWs are least likely to be hired in small facilities in rural areas. The influence of policy in supporting the professionalization of social service staff and the need for QSWs with expertise in gerontology, especially in rural NHs, are discussed. © 2016 National Association of Social Workers.

Displaying Wages as an Indicator of the Social Responsibility of Business in Accounting and Reporting

2017-12-01

Full Text Available The article is concerned with displaying wages in both accounting and reporting, in the context of social responsibility. The basic approaches to definition of social responsibility in the context of relations of employers and employees were considered. It was noted that an effective means of implementing the conception of social responsibility would be the preparation of integrated reporting, and for this purpose the elements of social responsibility of enterprises should be reflected in the accounting system. It is expedient to include in the indicators of social responsibility of the integrated reporting of enterprises the level of remuneration of the current character; the amount of compensation payments in connection with the completion of work and due to difficult working conditions, harmful industries; the amount of incentive payments as a result of developing the skill level and increasing labor efficiency; payments on the sectoral individual pensions and on social support programs, etc. The displaying of the proposed indicators in the reporting of enterprise would provide disclosure of information on the implementation of the principles of social responsibility and would inform the interested parties about the implementation of social programs and projects at the enterprise.

Social structures in the operating theatre: how contradicting rationalities and trust affect work.

This article is a report of a study of how healthcare professionals involved in surgery orientate themselves to their common task, and how this orientation can be affected by the social and organizational context. Previous research indicates that surgical teams are not as cohesive as could be expected and that communication failures frequently occur. However, little is known about how these problems are related to their social, cultural and organizational context. Semi-structured interviews were conducted with 15 healthcare professionals, representing all personnel categories of the surgical team. During the interview, a virtual model, visualizing a real operating theatre, was used to facilitate reflection. The interviews were conducted in 2009. Themes were created from the interviews, with a focus on similarities and differences. An activity analysis was conducted based on the themes. Poor team functionality and communication failures in the operating theatre can to some degree be explained by differences in activity orientation between professions and by insufficient support from social and organizational structures. Differences in activity orientation resulted in different views between professional groups in their perceptions of work activities, resulting in tension. Insufficient support resulted in communication thresholds that inhibited the sharing of information. Organizing work to promote cross-professional interaction can help the creation of social relations and norms, providing support for a common view. It can also help to decrease communication thresholds and establish stronger relations of trust. How this organization structure should be developed needs to be further investigated. © 2011 The Authors. Journal of Advanced Nursing © 2011 Blackwell Publishing Ltd.

Held, Mary L; Cuellar, Matthew

2016-09-01

Objective This study examined the direct and mediating effects of maternal social capital on health and well-being for native- and foreign-born Latina mothers and their children. Methods Data were drawn from the baseline and nine-year follow up waves of the Fragile Families and Child Well-being Study. The study included a sample of 874 Latina mothers. Mplus7 was used to perform structural equation modeling to determine whether exogenous indicators (age, education, and economic well-being) predicted social capital, whether social capital predicted mother and child well-being, and whether mediating effects helped explain each relationship. Results For native-born Latinas (n = 540), social capital did not predict maternal or child well-being. However, social capital significantly mediated the effects of age, education, and economic well-being on maternal well-being. For foreign-born Latinas (n = 334), social capital was a significant predictor of maternal well-being. Social capital also mediated the effects of age, education, and economic well-being on maternal, but not child well-being. Younger and foreign-born Latinas who report higher educational attainment and economic well-being have greater social capital, and thus better self-reported health. Conclusion Findings suggest that social capital is particularly relevant to the health of foreign-born Latinas. For all Latina mothers, social capital may serve as a protective mitigating factor to better health. Health service providers should evaluate the potential to integrate programs that promote social capital accumulation for Latinas. Further research should examine factors to improve the health of Latinas' children.

Social isolation has significant long-term psychological and physiological consequences. Both social isolation and traumatic brain injury (TBI) alter normal brain function and structure. However, the influence of social isolation on recovery from TBI is unclear. This study aims to evaluate if social isolation exacerbates the anatomical and functional deficits after TBI in young rats. Juvenile male rats were divided into four groups; sham operated control with social contacts, sham control with social isolation, TBI with social contacts, and TBI with social isolation. During four weeks after brain injury in juvenile rats, we evaluated the animal behaviors by T-maze and open-field tests, recorded brain activity with electrocorticograms and assessed structural changes by histological procedures in the hippocampal dentate gyrus, CA1, and CA3 areas. Our findings revealed significant memory impairments and hyperactivity conditions in rats with TBI and social isolation compared to the other groups. Histological assessments showed an increase of the mean number of dark neurons, apoptotic cells, and caspase-3 positive cells in all tested areas of the hippocampus in TBI rats with and without social isolation compared to sham rats. Furthermore, social isolation significantly increased the number of dark cells, apoptotic neurons, and caspase-3 positive cells in the hippocampal CA3 region in rats with TBI. This study indicates the harmful effect of social isolation on anatomical and functional deficits induced by TBI in juvenile rats. Prevention of social isolation may improve the outcome of TBI.

Malaysia is a Southeast Asian country in which multiple languages are prominently spoken, including English and Mandarin Chinese. As psychological science continues to develop within Malaysia, there is a need for psychometrically sound instruments that measure psychological phenomena in multiple languages. For example, assessment tools for measuring social desirability could be a useful addition in psychological assessments and research studies in a Malaysian context. This study examined the psychometric performance of the English and Mandarin Chinese versions of the Marlowe-Crowne Social Desirability Scale when used in Malaysia. Two hundred and eighty-three students (64% female; 83% Chinese, 9% Indian) from two college campuses completed the Marlowe-Crowne Social Desirability Scale in their language of choice (i.e., English or Mandarin Chinese). Proposed factor structures were compared with confirmatory factor analysis, and multiple indicators-multiple causes models were used to examine measurement invariance across language and sex. Factor analyses supported a two-factor structure (i.e., Attribution and Denial) for the measure. Invariance tests revealed the scale was invariant by sex, indicating that social desirability can be interpreted similarly across sex. The scale was partially invariant by language version, with some non-invariance observed within the Denial factor. Non-invariance may be related to differences in the English and Mandarin Chinese languages, as well as cultural differences. Directions for further research include examining the measurement of social desirability in other contexts where both English and Mandarin Chinese are spoken (i.e., China) and further examining the causes of non-invariance on specific items. © 2016 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

Composition and structure of a large online social network in The Netherlands.

Rense Corten

Full Text Available Limitations in data collection have long been an obstacle in research on friendship networks. Most earlier studies use either a sample of ego-networks, or complete network data on a relatively small group (e.g., a single organization. The rise of online social networking services such as Friendster and Facebook, however, provides researchers with opportunities to study friendship networks on a much larger scale. This study uses complete network data from Hyves, a popular online social networking service in The Netherlands, comprising over eight million members and over 400 million online friendship relations. In the first study of its kind for The Netherlands, I examine the structure of this network in terms of the degree distribution, characteristic path length, clustering, and degree assortativity. Results indicate that this network shares features of other large complex networks, but also deviates in other respects. In addition, a comparison with other online social networks shows that these networks show remarkable similarities.

To characterize economic development and diagnose the economic health condition, several popular indices such as gross domestic product (GDP), industrial structure and income growth are widely applied. However, computing these indices based on traditional economic census is usually costly and resources consuming, and more importantly, following a long time delay. In this paper, we analyzed nearly 200 million users' activities for four consecutive years in the largest social network (Sina Microblog) in China, aiming at exploring latent relationships between the online social activities and local economic status. Results indicate that online social activity has a strong correlation with local economic development and industrial structure, and more interestingly, allows revealing the macro-economic structure instantaneously with nearly no cost. Beyond, this work also provides a new venue to identify risky signal in local economic structure.

Mass media influence spreading in social networks with community structure

Candia, Julián; Mazzitello, Karina I.

2008-07-01

We study an extension of Axelrod's model for social influence, in which cultural drift is represented as random perturbations, while mass media are introduced by means of an external field. In this scenario, we investigate how the modular structure of social networks affects the propagation of mass media messages across a society. The community structure of social networks is represented by coupled random networks, in which two random graphs are connected by intercommunity links. Considering inhomogeneous mass media fields, we study the conditions for successful message spreading and find a novel phase diagram in the multidimensional parameter space. These findings show that social modularity effects are of paramount importance for designing successful, cost-effective advertising campaigns.

Information diffusion in structured online social networks

Li, Pei; Zhang, Yini; Qiao, Fengcai; Wang, Hui

Nowadays, due to the word-of-mouth effect, online social networks have been considered to be efficient approaches to conduct viral marketing, which makes it of great importance to understand the diffusion dynamics in online social networks. However, most research on diffusion dynamics in epidemiology and existing social networks cannot be applied directly to characterize online social networks. In this paper, we propose models to characterize the information diffusion in structured online social networks with push-based forwarding mechanism. We introduce the term user influence to characterize the average number of times that messages are browsed which is incurred by a given type user generating a message, and study the diffusion threshold, above which the user influence of generating a message will approach infinity. We conduct simulations and provide the simulation results, which are consistent with the theoretical analysis results perfectly. These results are of use in understanding the diffusion dynamics in online social networks and also critical for advertisers in viral marketing who want to estimate the user influence before posting an advertisement.

SOCIAL DISTANCES AS A FEATURE OF THE CONTEMPORARY RUSSIAN SOCIAL SPACE

Directory of Open Access Journals (Sweden)

Л А Беляева

2018-12-01

Full Text Available Social space is a theoretical construct that allows to consider many key problems of social development including the society’s consolidation. The author defines social space as a set of social statuses and distances. Their objective characteristics are interrelated with subjective indicators identified through the opinions of individuals. The balance of statuses and distances in society and the acceptability of this structure for the majority of population ensure the stability of society and effective social control. If this balance is disturbed, social tensions arise and threaten the stability and consolidation of society. Thus, the ideas of the theories of social space possess a considerable heuristic potential for revealing urgent problems of social development such as solidarity, social stratification and mobility, social networks and their interaction, connections of local communities within and with the world, interaction of structured social relations and individual and collective practices, genesis of social space as a result of social production represented by both things and relationships, etc. According to the theory of P. Bourdieu, the author con-siders social space as a structure of social statuses based on the set of different types of capital: economic, cultural, social, and symbolic. The author uses statistical data and results of the monitoring survey conducted on the all-Russian sample. The article proposes some tested empirical indicators that proved the increase of social distances in Russia due to the redistribution of economic capital and, as a consequence, of cultural and social capitals. Thus, the social space of Russia cannot be considered stable. To ensure its greater stability we need a set of measures to reduce social distances: re-industrialization to create high-tech jobs, development of digital economy, and improvement of the mass secondary and higher education system - these measures can create a basis for the

Brain structure links loneliness to social perception.

Loneliness is the distressing feeling associated with the perceived absence of satisfying social relationships. Loneliness is increasingly prevalent in modern societies and has detrimental effects on health and happiness. Although situational threats to social relationships can transiently induce the emotion of loneliness, susceptibility to loneliness is a stable trait that varies across individuals [6-8] and is to some extent heritable. However, little is known about the neural processes associated with loneliness (but see [12-14]). Here, we hypothesized that individual differences in loneliness might be reflected in the structure of the brain regions associated with social processes. To test this hypothesis, we used voxel-based morphometry and showed that lonely individuals have less gray matter in the left posterior superior temporal sulcus (pSTS)--an area implicated in basic social perception. As this finding predicted, we further confirmed that loneliness was associated with difficulty in processing social cues. Although other sociopsychological factors such as social network size, anxiety, and empathy independently contributed to loneliness, only basic social perception skills mediated the association between the pSTS volume and loneliness. Taken together, our results suggest that basic social perceptual abilities play an important role in shaping an individual's loneliness. Copyright © 2012 Elsevier Ltd. All rights reserved.

Virality Prediction and Community Structure in Social Networks

Science.gov (United States)

Weng, Lilian; Menczer, Filippo; Ahn, Yong-Yeol

2013-08-01

How does network structure affect diffusion? Recent studies suggest that the answer depends on the type of contagion. Complex contagions, unlike infectious diseases (simple contagions), are affected by social reinforcement and homophily. Hence, the spread within highly clustered communities is enhanced, while diffusion across communities is hampered. A common hypothesis is that memes and behaviors are complex contagions. We show that, while most memes indeed spread like complex contagions, a few viral memes spread across many communities, like diseases. We demonstrate that the future popularity of a meme can be predicted by quantifying its early spreading pattern in terms of community concentration. The more communities a meme permeates, the more viral it is. We present a practical method to translate data about community structure into predictive knowledge about what information will spread widely. This connection contributes to our understanding in computational social science, social media analytics, and marketing applications.

Gene-Culture Coevolution in a Social Cetacean: Integrating Acoustic and Genetic Data to Understand Population Structure in the Short-Finned Pilot Whale (Globicephala macrorhynchus)

Science.gov (United States)

Van Cise, Amy

The evolutionary ecology of a species is driven by a combination of random events, ecological and environmental mechanisms, and social behavior. Gene-culture coevolutionary theory attempts to understand the evolutionary trajectory of a species by examining the interactions between these potential drivers. Further, our choice of data type will affect the patterns we observe, therefore by integrating several types of data we achieve a holistic understanding of the various aspects of evolutionary ecology within a species. In order to understand population structure in short-finned pilot whales, I use a combination of genetic and acoustic data to examine structure on evolutionary (genetic) and cultural (acoustic) timescales. I first examine structure among geographic populations in the Pacific Ocean. Using genetic sequences from the mitochondrial control region, I show that two genetically and morphologically distinct types of short-finned pilot whale, described off the coast of Japan, have non-overlapping distributions throughout their range in the Pacific Ocean. Analysis of the acoustic features of their social calls indicates that they are acoustically differentiated, possibly due to limited communication between the two types. This evidence supports the hypothesis that the two types may be separate species or subspecies. Next, I examine structure among island communities and social groups within the Hawaiian Island population of short-finned pilot whales. Using a combination of mitochondrial and nuclear DNA, I showed that the hierarchical social structure in Hawaiian pilot whales is driven by genetic relatedness; individuals remain in groups with their immediate family members, and preferentially associate with relatives. Similarly, social structure affects genetic differentiation, likely by restricting access to mates. Acoustic differentiation among social groups indicates that social structure may also restrict the flow of cultural information, such as vocal

Evolution of individual versus social learning on social networks.

Tamura, Kohei; Kobayashi, Yutaka; Ihara, Yasuo

2015-03-06

A number of studies have investigated the roles played by individual and social learning in cultural phenomena and the relative advantages of the two learning strategies in variable environments. Because social learning involves the acquisition of behaviours from others, its utility depends on the availability of 'cultural models' exhibiting adaptive behaviours. This indicates that social networks play an essential role in the evolution of learning. However, possible effects of social structure on the evolution of learning have not been fully explored. Here, we develop a mathematical model to explore the evolutionary dynamics of learning strategies on social networks. We first derive the condition under which social learners (SLs) are selectively favoured over individual learners in a broad range of social network. We then obtain an analytical approximation of the long-term average frequency of SLs in homogeneous networks, from which we specify the condition, in terms of three relatedness measures, for social structure to facilitate the long-term evolution of social learning. Finally, we evaluate our approximation by Monte Carlo simulations in complete graphs, regular random graphs and scale-free networks. We formally show that whether social structure favours the evolution of social learning is determined by the relative magnitudes of two effects of social structure: localization in competition, by which competition between learning strategies is evaded, and localization in cultural transmission, which slows down the spread of adaptive traits. In addition, our estimates of the relatedness measures suggest that social structure disfavours the evolution of social learning when selection is weak. © 2015 The Author(s) Published by the Royal Society.

Full Text Available Currently companies have to think about its management system to meet not only their economic interests but also their social interests aiming at the activities’ sustainability and longevity. In this research, the goal is to identify the Nash equilibrium point in the bi-matrix game of economic and social indicators of the companies of Public Utilities sector listed on the BM & FBovespa. The research was conducted with a sample of 26 companies. To evaluate the economic performance it was used the profitability and market indicators; for evaluating the social performance, it was used the indicators derived from the VAD (Value Added Statement. In the estimation of earnings among indicators, it was used the standard parameters of the multiple linear regression. The obtained results highlighted the existence of at least one point of equilibrium for the years analyzed and, especially in the models, two points of equilibrium were proposed for 2009 and 2011 and three for 2010. It is noteworthy that, in the proposed model it was confirmed the hypothesis of the existence of at least one point of equilibrium. Thus, it was possible to meet the research objective, namely, that it is possible to meet both economic aspects and the social aspects of the companies when the indicators are taken as basic information.

Gagné, Thierry; Frohlich, Katherine L; Abel, Thomas

2015-10-01

Associations between social status and health behaviours are well documented, but the mechanisms involved are less understood. Cultural capital theory may contribute to a better understanding by expanding the scope of inequality indicators to include individuals' knowledge, skills, beliefs and material goods to examine how these indicators impact individuals' health lifestyles. We explore the structure and applicability of a set of cultural capital indicators in the empirical exploration of smoking behaviour among young male adults. We analysed data from the Swiss Federal Survey of Adolescents (CH-X) 2010-11 panel of young Swiss males (n = 10 736). A set of nine theoretically relevant variables (including incorporated, institutionalized and objectified cultural capital) were investigated using exploratory factor analysis. Regression models were run to observe the association between factor scores and smoking outcomes. Outcome measures consisted of daily smoking status and the number of cigarettes smoked by daily smokers. Cultural capital indicators aggregated in a three-factor solution representing 'health values', 'education and knowledge' and 'family resources'. Each factor score predicted the smoking outcomes. In young males, scoring low on health values, education and knowledge and family resources was associated with a higher risk of being a daily smoker and of smoking more cigarettes daily. Cultural capital measures that include, but go beyond, educational attainment can improve prediction models of smoking in young male adults. New measures of cultural capital may thus contribute to our understanding of the social status-based resources that individuals can use towards health behaviours. © The Author 2015.

Self-perceived class results from directly questioning subjects about his or her social class. The aim of this investigation was to analyse self-perceived class in relation to other indicator variables of socioeconomic level. Data from the 1994 Catalan Health Interview Survey, a cross-sectional survey of a representative sample of the non-institutionalised population of Catalonia was used. We conducted a discriminant analysis to compute the degree of right classification when different socioeconomic variables potentially related to self-perceived class were considered. All subjects who directly answered the questionnaire were included (N = 12,245). With the aim of obtaining the discriminant functions in a group of subjects and to validate it in another one, the subjects were divided into two random samples, containing approximately 75% and 25% of subjects (analysis sample, n = 9,248; and validation sample, n = 2,997). The final function for men and women included level of education, social class (based in occupation) and equivalent income. This function correctly classified 40.9% of the subjects in the analysis sample and 39.2% in the validation sample. Two other functions were selected for men and women separately. In men, the function included level of education, professional category, and family income (39.2% of classification in analysis sample and 37.2% in validation sample). In women, the function (level of education, working status, and equivalent income) correctly classified 40.3% of women in analysis sample whereas the percentage was 38.9% in validation sample. The percentages of right classification were higher for the highest and lowest classes. These results show the utility of a simple variable to self-position within the social scale. Self-perceived class is related to education, income, and working determinants.

Time Allocation in Social Networks: Correlation Between Social Structure and Human Communication Dynamics

Science.gov (United States)

Miritello, Giovanna; Lara, Rubén; Moro, Esteban

Recent research has shown the deep impact of the dynamics of human interactions (or temporal social networks) on the spreading of information, opinion formation, etc. In general, the bursty nature of human interactions lowers the interaction between people to the extent that both the speed and reach of information diffusion are diminished. Using a large database of 20 million users of mobile phone calls we show evidence this effect is not homogeneous in the social network but in fact, there is a large correlation between this effect and the social topological structure around a given individual. In particular, we show that social relations of hubs in a network are relatively weaker from the dynamical point than those that are poorer connected in the information diffusion process. Our results show the importance of the temporal patterns of communication when analyzing and modeling dynamical process on social networks.

Human social evolution has most often been treated in a piecemeal fashion, with studies focusing on the evolution of specific components of human society such as pair-bonding, cooperative hunting, male provisioning, grandmothering, cooperative breeding, food sharing, male competition, male violence, sexual coercion, territoriality, and between-group conflicts. Evolutionary models about any one of those components are usually concerned with two categories of questions, one relating to the origins of the component and the other to its impact on the evolution of human cognition and social life. Remarkably few studies have been concerned with the evolution of the entity that integrates all components, the human social system itself. That social system has as its core feature human social structure, which I define here as the common denominator of all human societies in terms of group composition, mating system, residence patterns, and kinship structures. The paucity of information on the evolution of human social structure poses substantial problems because that information is useful, if not essential, to assess both the origins and impact of any particular aspect of human society.

2013-11-01

Full Text Available The present journal recently stated in the call for a special issue on social sustainability, “[t]hough sustainable development is said to rest on ‘three pillars’, one of these—social sustainability—has received significantly less attention than its bio-physical environmental and economic counterparts”. The current issue promises to engage the concepts of “development sustainability”, “bridge sustainability” and “maintenance sustainability” and the tensions between these different aspects of social sustainability. The aim of the present study is to identify the visibility of disabled people in the academic social sustainability literature, to ascertain the impact and promises of social sustainability indicators put forward in the same literature and to engage especially with the concepts of “development sustainability”, “bridge sustainability” and “maintenance sustainability” through disability studies and ability studies lenses. We report that disabled people are barely covered in the academic social sustainability literature; of the 5165 academic articles investigated only 26 had content related to disabled people and social sustainability. We also conclude that social sustainability indicators evident in the 1909 academic articles with the phrase “social sustainability” in the abstract mostly focused on products and did not reflect yet the goals outlined in the “development sustainability” aspect of social sustainability proposed by Vallance such as basic needs, building social capital, justice and so on. We posit that if the focus within the social sustainability discourse shifts more toward the social that an active presence of disabled people in this discourse is essential to disabled people. We showcase the utility of an ability studies lens to further the development and application of the “development sustainability”, “bridge sustainability” and “maintenance sustainability�

Social cognition is a topic of enormous interest and much research, but we are far from having an agreed taxonomy or factor structure of relevant processes. The aim of this review is to outline briefly what is known about the structure of social cognition and to suggest how further progress can be made to delineate the in(ter)dependence of core sociocognitive processes. We focus in particular on several processes that have been discussed and tested together in typical and atypical (notably autism spectrum disorder) groups: imitation, biological motion, empathy, and theory of mind. We consider the domain specificity/generality of core processes in social learning, reward, and attention, and we highlight the potential relevance of dual-process theories that distinguish systems for fast/automatic and slow/effortful processing. We conclude with methodological and conceptual suggestions for future progress in uncovering the structure of social cognition.

Oxytocin as an Indicator of Psychological and Social Well-Being in Domesticated Animals: A Critical Review

Directory of Open Access Journals (Sweden)

Jean-Loup Rault

2017-09-01

Full Text Available Oxytocin is often portrayed as a hormone specific to social behavior, reflective of positive welfare states, and linked to mental states. Research on oxytocin in domesticated animal species has been few to date but is rapidly increasing (in dog, pig, cattle, sheep, with direct implications for animal welfare. This review evaluates the evidence for the specificity of oxytocin as an indicator of: 1. Social, 2. Positive, and 3. Psychological well-being. Oxytocin has most often been studied in socially relevant paradigms, with a lack of non-social control paradigms. Oxytocin research appears biased toward investigating positive valence, with a lack of control in valence or arousal. Oxytocin actions are modulated by the environmental and social contexts, which are important factors to consider. Limited evidence supports that oxytocin's actions are linked to psychological states; nevertheless whether this is a direct effect of oxytocin per se remains to be demonstrated. Overall, it is premature to judge oxytocin's potential as an animal welfare indicator given the few and discrepant findings and a lack of standardization in methodology. We cover potential causes for discrepancies and suggest solutions through appropriate methodological design, oxytocin sampling or delivery, analysis and reporting. Of particular interest, the oxytocinergic system as a whole remains poorly understood. Appreciation for the differences that social contact and group living pose in domesticated species and the way they interact with humans should be key considerations in using oxytocin as a psychosocial indicator of well-being.

Estimates from archaeological data of the numbers in the elite classes, nonelite occupational specialists, density of population, city size, and size of political units in the ancient Maya civilization suggest that there was a quantum shift in rate of development in the Early Classic period, associated with intensification of agriculture, and that the social structure approximated to a generalized feudal pattern.

Optical-based smart structures for tamper-indicating applications

International Nuclear Information System (INIS)

Sliva, P.; Anheier, N.C.; Simmons, K.L.; Undem, H.A.

1996-11-01

This report is a compilation of several related projects performed from 1991 through 1996 concerning the design, construction, and application of optical-based smart structure to tamper-indicating and sensing secure containers. Due to several influences, the projects were carried through to varying degrees of completion. Cancellation of the overall project at the client level motivated the authors to gather all of the technology and ideas about smart structures developed during these several projects, whether completed or just conceptualized, into one document. Although each section individually discusses a specific project, the overall document is written chronologically with each successive section showing how increased smart structure complexity was integrated into the container

We investigated the reciprocal relationship between individual social capital and perceived mental and physical health in the UK. Using data from the British Household Panel Survey from 1991 to 2008, we fitted cross-lagged structural equation models that include three indicators of social capital vis. social participation, social network, and loneliness. Given that multiple measurement points (level 1) are nested within individuals (level 2), we also applied a multilevel model to allow for residual variation in the outcomes at the occasion and individual levels. Controlling for gender, age, employment status, educational attainment, marital status, household wealth, and region, our analyses suggest that social participation predicts subsequent change in perceived mental health, and vice versa. However, whilst loneliness is found to be significantly related to perceived mental and physical health, reciprocal causality is not found for perceived mental health. Furthermore, we find evidence for reverse effects with both perceived mental and physical health appearing to be the dominant causal factor with respect to the prospective level of social network. Our findings thus shed further light on the importance of social participation and social inclusion in health promotion and aid the development of more effective public health policies in the UK.

In this paper we investigate the effectiveness of family policies in the context of the structure of a society. We use an agent-based model to analyse the impact of policies on individual fertility decisions and on fertility at the aggregate level. The crucial features of our model are the interactions between family policies and social structure, the agents´ heterogeneity and the structure and influence of the social network. This modelling framework allows us to disentangle the direct effec...

The present study was aimed at analysing how social sports projects are evaluated so as to draw up and develop indicators of success regarding social programmes' efficacy and effectiveness. This was a descriptive survey. The sample consisted of 51 participants, male (n=29) and female (n=22), from the Nova Descoberta project whose ages ranged from 8 to 17. Data was obtained from a semi-directed survey having open items covering 10 topics; it was carried out with children and adolescents over a 2-year period (2007-2008). Documental data was also obtained from schools which had agreed to cooperate with the project. There were no statistically significant differences (pperformance of survey group participants and those who had not joined the project in terms of scholastic performance during 2007. A significant difference (psports projects. The manifestation of other characteristics in the environment could have interfered with participation and involvement in physical activity and, consequently, with the children and adolescents' health and quality of life. It was found that school work performance indicators could be taken together with other indicators, such as development of various abilities, participation in other activities, activity motivation, behaviour and attitudes at home and at school, for evaluating social projects.

For the past 20 years, the New Zealand Deprivation Index (NZDep) has been the universal measure of area-based social circumstances for New Zealand (NZ) and often the key social determinant used in population health and social research. This paper presents the first theoretical and methodological shift in the measurement of area deprivation in New Zealand since the 1990s and describes the development of the New Zealand Index of Multiple Deprivation (IMD). We briefly describe the development of Data Zones, an intermediary geographical scale, before outlining the development of the New Zealand Index of Multiple Deprivation (IMD), which uses routine datasets and methods comparable to current international deprivation indices. We identified 28 indicators of deprivation from national health, social development, taxation, education, police databases, geospatial data providers and the 2013 Census, all of which represented seven Domains of deprivation: Employment; Income; Crime; Housing; Health; Education; and Geographical Access. The IMD is the combination of these seven Domains. The Domains may be used individually or in combination, to explore the geography of deprivation and its association with a given health or social outcome. Geographic variations in the distribution of the IMD and its Domains were found among the District Health Boards in NZ, suggesting that factors underpinning overall deprivation are inconsistent across the country. With the exception of the Access Domain, the IMD and its Domains were statistically and moderately-to-strongly associated with both smoking rates and household poverty. The IMD provides a more nuanced view of area deprivation circumstances in Aotearoa NZ. Our vision is for the IMD and the Data Zones to be widely used to inform research, policy and resource allocation projects, providing a better measurement of area deprivation in NZ, improved outcomes for Māori, and a more consistent approach to reporting and monitoring the social

Full Text Available The article is devoted to methodological foundations of research of leader’s personal qualities. In difference from the previous work, which was devoted to a research of personal qualities of heads, including civil officers, at works of Plato, Aristotle and M. Weber, where were shown empirical models of structure of personal qualities of heads: instrumental-rational and value-rational social actions. This publication presents the empirical models of structure of personal qualities of heads of affective type of M. Weber’s social action. Thanks to it, M. Weber’s concept about social action receives one more approach to verification in practice. The following directions of social researches are allocated. The first direction. When in structure of personal qualities the emotional component is a dominant (“emotional unbalance”, in comparison with intellectual, moral, strong-willed and other personal qualities (diplomacy, social experience, and so forth. Those people, whose indicators of emotional unbalance are in extreme, in maximum borders - carry to psychopaths and they are an object of clinical psychology and medicine. The second direction. When in structure of personal qualities emotional unbalance competes on equal terms (equally has bright difference, a deviation from average values to intellectual, moral and strong-willed qualities. The third direction. When in structure of personal qualities intellectual, moral and strong-willed and others personal qualities dominate over affective lines.

Towards Coupling of Macroseismic Intensity with Structural Damage Indicators

Kouteva, Mihaela; Boshnakov, Krasimir

2016-04-01

Knowledge on basic data of ground motion acceleration time histories during earthquakes is essential to understanding the earthquake resistant behaviour of structures. Peak and integral ground motion parameters such as peak ground motion values (acceleration, velocity and displacement), measures of the frequency content of ground motion, duration of strong shaking and various intensity measures play important roles in seismic evaluation of existing facilities and design of new systems. Macroseismic intensity is an earthquake measure related to seismic hazard and seismic risk description. Having detailed ideas on the correlations between the earthquake damage potential and macroseismic intensity is an important issue in engineering seismology and earthquake engineering. Reliable earthquake hazard estimation is the major prerequisite to successful disaster risk management. The usage of advanced earthquake engineering approaches for structural response modelling is essential for reliable evaluation of the accumulated damages in the existing buildings and structures due to the history of seismic actions, occurred during their lifetime. Full nonlinear analysis taking into account single event or series of earthquakes and the large set of elaborated damage indices are suitable contemporary tools to cope with this responsible task. This paper presents some results on the correlation between observational damage states, ground motion parameters and selected analytical damage indices. Damage indices are computed on the base of nonlinear time history analysis of test reinforced structure, characterising the building stock of the Mediterranean region designed according the earthquake resistant requirements in mid XX-th century.

Social learning of vocal structure in a nonhuman primate?

Directory of Open Access Journals (Sweden)

Lemasson Alban

2011-12-01

Full Text Available Abstract Background Non-human primate communication is thought to be fundamentally different from human speech, mainly due to vast differences in vocal control. The lack of these abilities in non-human primates is especially striking if compared to some marine mammals and bird species, which has generated somewhat of an evolutionary conundrum. What are the biological roots and underlying evolutionary pressures of the human ability to voluntarily control sound production and learn the vocal utterances of others? One hypothesis is that this capacity has evolved gradually in humans from an ancestral stage that resembled the vocal behavior of modern primates. Support for this has come from studies that have documented limited vocal flexibility and convergence in different primate species, typically in calls used during social interactions. The mechanisms underlying these patterns, however, are currently unknown. Specifically, it has been difficult to rule out explanations based on genetic relatedness, suggesting that such vocal flexibility may not be the result of social learning. Results To address this point, we compared the degree of acoustic similarity of contact calls in free-ranging Campbell's monkeys as a function of their social bonds and genetic relatedness. We calculated three different indices to compare the similarities between the calls' frequency contours, the duration of grooming interactions and the microsatellite-based genetic relatedness between partners. We found a significantly positive relation between bond strength and acoustic similarity that was independent of genetic relatedness. Conclusion Genetic factors determine the general species-specific call repertoire of a primate species, while social factors can influence the fine structure of some the call types. The finding is in line with the more general hypothesis that human speech has evolved gradually from earlier primate-like vocal communication.

Inclusion of social indicators in decision support tools for the selection of sustainable site remediation options.

Sustainable remediation requires a balanced decision-making process in which environmental, economic and social aspects of different remediation options are all considered together and the optimum remediation solution is selected. More attention has been paid to the evaluation of environmental and economic aspects, in particular to reduce the human and environmental risks and the remediation costs, to the exclusion of social aspects of remediation. This paper investigates how social aspects are currently considered in sustainability assessments of remediation projects. A selection of decision support tools (DSTs), used for the sustainability assessment of a remediation project, is analyzed to define how social aspects are considered in those tools. The social indicator categories of the Sustainable Remediation Forum - United Kingdom (SuRF-UK), are used as a basis for this evaluation. The consideration of social aspects in the investigated decision support tools is limited, but a clear increase is noticed in more recently developed tools. Among the five social indicator categories defined by SuRF-UK to facilitate a holistic consideration of social aspects of a remediation project only "Human health and safety" is systematically taken into account. "Neighbourhood and locality" is also often addressed, mostly emphasizing the potential disturbance caused by the remediation activities. However, the evaluation of 'Ethics and Equality', Communities and community involvement', and 'Uncertainty and evidence' is often neglected. Nevertheless, concrete examples can be found in some of the investigated tools. Specific legislation, standard procedures, and guidelines that have to be followed in a region or country are mainly been set up in the context of protecting human and ecosystem health, safety and prevention of nuisance. However, they sometimes already include some of the aspects addressed by the social indicators. In this perspective the use of DST to evaluate the

To assess trends in social inequalities among 2,624 elderly living in Belo Horizonte, Brazil, in three domains of the World Health Organization's Active Aging model (physical environment, social determinants, use of health services) and health status indicators. Data came from two representative household surveys conducted in 2003 and 2010. Social inequality was measured by the slope and the relative index of inequality. Educational level was used to define socioeconomic status. Significant improvements were observed in the prevalence rates of 7 out of 12 indicators. However, the social inequalities persisted through 10 out of 12 selected active aging and health status indicators, except for fear of falling on the sidewalks/crossing the streets and fear of being robbed. Social inequalities persistence might be assigned to the continuity of unequal distribution of resources among groups with different educational levels. © The Author(s) 2015.

Built and social environments, including one's perception of their environment, are important determinants of health. The intersection of gender and HIV status may complicate the role of neighborhood cohesion in safety, personal well-being, and health outcomes for populations impacted by social and structural inequities. Among women in particular, social cohesion within the neighborhood they reside in may have a greater influence on health outcomes compared to their male counterparts. We sought to examine perception of neighborhood cohesion (validated scale with a range 0-100, with higher scores indicating higher perceived neighborhood cohesion) among women living with HIV, impacted by social-structural inequities, receiving combination antiretroviral therapy, and enrolled in the Longitudinal Investigations into Supportive Ancillary health services (LISA) study in British Columbia, Canada. Cross-sectional data on neighborhood cohesion and socio-demographic data were collected in an interviewer-administered survey. Of the 1,000 LISA participants interviewed, 908 (including 249 women and 659 men) had complete data for the variables of interest. At the bivariate level, women had worse perceived neighborhood cohesion scores compared to men (median: 56 [95% CI: 44-66] vs. 60 [95% CI: 47-71]). Multivariable model results indicated that for women living with HIV in our sample, greater neighborhood cohesion scores were positively associated with stable housing (β coefficient = 7.85; 95% CI: 3.61, 12.10, p perceptions of neighborhood cohesion.

Full Text Available BACKGROUND Social factors in CLHA play important role in growth indicators. Both parents alive, loss of breadwinner of the family, widows working for children, orphaned CLHA, guardian and NGO’s taking care of CLHA, below poverty line status are some of the social factors that will have impact on growth indicators. This study was done to study these factors influence on growth indicators. MATERIALS AND METHODS Prospective study from April 2014 to March 2015. All children on ART. Consent was obtained. Demographic data, height and weight measured monthly. Nutritional counseling and adherence counseling was given to all CLHA and caretakers. Gain in mean weight and height were tabulated. Data were grouped with both parents alive, mother alive, father alive, both parent dead, under guardian care, under NGO or GO care, two sibling families, below and above poverty line, sibling with HIV, at least one family member earning and two family members earning. Results were analysed. RESULTS Subjects 212. Male:female ratio 126:86. Mean age 9.6 years. (Males 9.8 and females 9.4 years. Mean duration of ART 45.5 months. 35% had both parents alive, 38% only mother alive, 8% only father alive and 17% both parents dead. 40% of orphaned taken care by guardians, rest by NGO’s. 9 families had more than 2 siblings. 21% had no earning family members. 80% were below poverty line. Mean increase in height was 5.75cms and weight was 2.87kgs during one year. No difference in gain in height in social groups. Orphaned children taken care by NGO’s and guardians have high gain in weight. Number of earning member does not influence in gain in weight. Gain in weight in above poverty line is better than below poverty line. CLHA under father’s care gained only 2.47kgs. CLHA with mother’s care gained more weight than father’s care. CONCLUSION 20% CLHA were orphaned and without earning member. Mothers, income of the family, NGO’s homes and guardians improve growth

2014-01-01

This article presents 2 studies testing Paulhus's (2002) assumption that unconscious self-enhancement and conscious impression management represent separate processes of socially desirable responding (SDR) that can be observed within 2 content domains (egoistic and moralistic bias). In Study 1, we devised egoistic and moralistic SDR scales intended to measure self-enhancement in honest responding and impression management under demands for positive self-presentation. In Study 2, we correlated scores on these scales with external indicators of self-enhancement and impression management. In honest responding, both SDR scales most strongly correlated with self-enhancement indicators, whereas under demands for positive self-presentation they correlated more strongly with external measures of impression management.

Complex Social Structure of an Endangered Population of Bottlenose Dolphins (Tursiops truncatus in the Aeolian Archipelago (Italy.

Directory of Open Access Journals (Sweden)

Monica F Blasi

Full Text Available We investigated social structure and association patterns for a small population of Mediterranean bottlenose dolphins, Tursiops truncatus, inhabiting the Aeolian Archipelago (southern Italy. Specifically we evaluate the role of sex and age composition, residency patterns and interaction with trammel nets on this social organization. Association data for 23 regularly sighted individuals were obtained from summer photoidentification surveys collected from 2005-2012. Using a combined cluster and social network analysis approach, we found associations between dolphins were hierarchically structured, where two mixed-sex social units were subdivided into smaller temporarily dynamic groups. We found non-random and long-term preferred associations in the population; however, the degree of social cohesion, residence pattern and interaction with trammel nets differed considerably between the two social units. Six of eight females occurred in the more resident social unit-1; in addition, social unit-1 individuals had significantly stronger associations, higher preferred associates, lived in larger groups and occurred less frequently with trammel nets. Nine of eleven males were clustered in social unit-2 and five of these males, interacting with trammel nets, formed small groups and preferred associations. We propose that female and male groups associate in the study area during the breeding season and that some males choose to interact with reproductive females forming a distinct but interrelated social unit. Other males may be associating in a larger fission-fusion network, which consists of dolphins that appear to temporarily join the network from the coastal population. We cannot exclude that some males specialized in trammel net foraging, suggesting that this foraging technique may favor a solitary lifestyle. Large group sizes and high degree of social cohesion for females could be an indication of greater protection and more efficiency in detecting

The structural and functional brain networks that support human social networks.

Social skills rely on a specific set of cognitive processes, raising the possibility that individual differences in social networks are related to differences in specific brain structural and functional networks. Here, we tested this hypothesis with multimodality neuroimaging. With diffusion MRI (DMRI), we showed that differences in structural integrity of particular white matter (WM) tracts, including cingulum bundle, extreme capsule and arcuate fasciculus were associated with an individual's social network size (SNS). A voxel-based morphology analysis demonstrated correlations between gray matter (GM) volume and SNS in limbic and temporal lobe regions. These structural changes co-occured with functional network differences. As a function of SNS, dorsomedial and dorsolateral prefrontal cortex showed altered resting-state functional connectivity with the default mode network (DMN). Finally, we integrated these three complementary methods, interrogating the relationship between social GM clusters and specific WM and resting-state networks (RSNs). Probabilistic tractography seeded in these GM nodes utilized the SNS-related WM pathways. Further, the spatial and functional overlap between the social GM clusters and the DMN was significantly closer than other control RSNs. These integrative analyses provide convergent evidence of the role of specific circuits in SNS, likely supporting the adaptive behavior necessary for success in extensive social environments.

2018-01-01

Full Text Available Studies on sustainable construction materials are on the rise with their environmental, social, and economic benefits. This study identifies the key indicators for measuring sustainable construction materials. The design used for the study was that of a survey which relied on a questionnaire with five-point Likert scale to generate data for the analysis. For this purpose, 25 indicators from the three dimensions (environmental, social, and economic identified from the literature were presented to the respondents in a structured questionnaire, and responses were collected and analysed using SPSS. The study identified three key environmental indicators for measuring sustainable construction materials, and these indicators are human toxicity, climate change, and solid waste. Furthermore, adaptability, thermal comfort, local resources, and housing for all were identified as the four key social indicators for sustainable construction materials. In addition, maintenance cost, operational cost, initial cost, long-term savings, and life span were found to be the five key economic indicators for measuring sustainable construction materials. The study therefore suggests that these twelve indicators should be considered in future studies that seek to measure sustainable construction materials.

Social structure of the harem-forming promiscuous fruit bat, Cynopterus sphinx, is the harem truly important?

Garg, Kritika M; Chattopadhyay, Balaji; Ramakrishnan, Uma

2018-02-01

Bats are social animals and display a diverse variety of mating and social systems, with most species exhibiting some form of polygyny. Their social organization is fluid and individuals frequently switch partners and roosting sites. While harem-like social organization is observed in multiple tropical species, its importance is contested in many of them. In this study, we investigated the role of harems in the social organization of the old world fruit bat Cynopterus sphinx . Based on regular behavioural observations over a period of 20 months and genetic data from microsatellite markers, we observed that the social organization is flexible, individuals regularly shift between roosts and the social organization resembles a fission-fusion society. Behavioural and genetic analyses suggest that the harems are not strict units of social structure, and the colony does not show signatures of subdivision with harems as behavioural units. We also observed that there was no correlation between individuals with high association index and pairwise relatedness. Our findings indicate that similar to the mating system, the social organization of C. sphinx can also be categorized as a fission-fusion society, and hence the term 'harem' is a misnomer. We conclude that the social system of C. sphinx is flexible, with multi-male multi-female organization, and individuals tend to be loyal to a given area rather than a roost.

Specificity of cognitive structure in depression and social phobia: a comparison of interpersonal and achievement content.

2006-02-01

The comorbidity between the mood and anxiety is extensive and it is probable that individuals with these disorders share a number of cognitive characteristics. However, comorbidity rates with depression are not uniform among the various anxiety disorders. This study examined the common and distinguishing features of self-schematic structure in major depressive disorder and social anxiety compared to other anxiety disorders in general and to no psychiatric disturbance. Participants completed the Psychological Distance Scaling Task, which provided an index of the cognitive organization of positively and negatively valenced interpersonal and achievement self-referent content. The depression and social phobia groups were statistically equivalent on all indices of cognitive organization, and showed greater interconnectedness among interpersonal negative content than both control groups, and less interconnectedness among both positive interpersonal and achievement content than did nonpsychiatric controls. Psychiatric groups were equivalent on negative achievement content but showed greater interconnectedness than controls. This study had a modest sample size and the findings are constrained to females. Negative interpersonal content is more densely interconnected in individuals with social phobia and depression compared with both other anxiety disorder and nonpsychiatric controls. In addition, both social phobia and depression were associated with less interconnected positive content. These findings are indicative of similarities in the way self-schematic content may be organized in individuals with depression and social phobia. Theoretical explanations of these results and future research directions are discussed.

Although neuroscientific research has revealed experience-dependent brain changes across the life span in sensory, motor, and cognitive domains, plasticity relating to social capacities remains largely unknown. To investigate whether the targeted mental training of different cognitive and social skills can induce specific changes in brain morphology, we collected longitudinal magnetic resonance imaging (MRI) data throughout a 9-month mental training intervention from a large sample of adults between 20 and 55 years of age. By means of various daily mental exercises and weekly instructed group sessions, training protocols specifically addressed three functional domains: (i) mindfulness-based attention and interoception, (ii) socio-affective skills (compassion, dealing with difficult emotions, and prosocial motivation), and (iii) socio-cognitive skills (cognitive perspective-taking on self and others and metacognition). MRI-based cortical thickness analyses, contrasting the different training modules against each other, indicated spatially diverging changes in cortical morphology. Training of present-moment focused attention mostly led to increases in cortical thickness in prefrontal regions, socio-affective training induced plasticity in frontoinsular regions, and socio-cognitive training included change in inferior frontal and lateral temporal cortices. Module-specific structural brain changes correlated with training-induced behavioral improvements in the same individuals in domain-specific measures of attention, compassion, and cognitive perspective-taking, respectively, and overlapped with task-relevant functional networks. Our longitudinal findings indicate structural plasticity in well-known socio-affective and socio-cognitive brain networks in healthy adults based on targeted short daily mental practices. These findings could promote the development of evidence-based mental training interventions in clinical, educational, and corporate settings aimed at

Catastrophic declines in African great ape populations due to disease outbreaks have been reported in recent years, yet we rarely hear of similar disease impacts for the more solitary Asian great apes, or for smaller primates. We used an age-structured model of different primate social systems to illustrate that interactions between social structure and demography create 'dynamic constraints' on the pathogens that can establish and persist in primate host species with different social systems. We showed that this varies by disease transmission mode. Sexually transmitted infections (STIs) require high rates of transmissibility to persist within a primate population. In particular, for a unimale social system, STIs require extremely high rates of transmissibility for persistence, and remain at extremely low prevalence in small primates, but this is less constrained in longer-lived, larger-bodied primates. In contrast, aerosol transmitted infections (ATIs) spread and persist at high prevalence in medium and large primates with moderate transmissibility;, establishment and persistence in small-bodied primates require higher relative rates of transmissibility. Intragroup contact structure - the social network - creates different constraints for different transmission modes, and our model underscores the importance of intragroup contacts on infection prior to intergroup movement in a structured population. When alpha males dominate sexual encounters, the resulting disease transmission dynamics differ from when social interactions are dominated by mother-infant grooming events, for example. This has important repercussions for pathogen spread across populations. Our framework reveals essential social and demographic characteristics of primates that predispose them to different disease risks that will be important for disease management and conservation planning for protected primate populations.

We analyze China's rural-urban migration and endogenous social network structures using agent-based modeling. The agents from census micro data are located in their rural origin with an empirical-estimated prior propensity to move. The population-scale social network is a hybrid one, combining observed family ties and locations of the origin with a parameter space calibrated from census, survey and aggregate data and sampled using a stepwise Latin Hypercube Sampling method. At monthly intervals, some agents migrate and these migratory acts change the social network by turning within-nonmigrant connections to between-migrant-nonmigrant connections, turning local connections to nonlocal connections, and adding among-migrant connections. In turn, the changing social network structure updates migratory propensities of those well-connected nonmigrants who become more likely to move. These two processes iterate over time. Using a core-periphery method developed from the k -core decomposition method, we identify and quantify the network structural changes and map these changes with the migration acceleration patterns. We conclude that network structural changes are essential for explaining migration acceleration observed in China during the 1995-2000 period.

Quality measurement is an important component of healthcare reform. The relationship of quality indicators (QIs) for parent-delivered family support services to organizational social contexts known to improve quality is unexamined. This study employs data collected from 21 child mental health programs that deliver team-based family support services. Performance on two levels of QIs —those targeting the program and staff -- were significantly associated with organizational social context profiles and dimensions. High quality program policies are associated with positive organizational cultures and engaging climates. Inappropriate staff practices are associated with resistant cultures. Implications for organizational strategies to improve service quality are discussed. PMID:23709286

Full Text Available Corporate Social Responsibility (CSR, indicator used was the index of CSR disclosure with 64 companies listed in Indonesia Stock Exchange period of 2012 as the samples. This research used multiple regression analysis. The results show that institutional ownership, managerial and foreign has no effect on CSR. This indicates that the ownership structure could not improve CSR in the company. On the contrary, profitability has an influence on CSR. It indicates that companies with high profits have the fund flexibility to implement CSR programs that have been set. Moreover, corporate debt levels also affect the CSR with the negative direction. This means that companies with high debt levels will usually focus more on managing faced business risks rather than on CSR program. Last, company size has no effect on the company CSR.

Social relationships are multifaceted, and different social network components can operate via different processes to influence well-being. This study examined associations of social network structure and relationship quality (positive and negative social exchanges) with mental health in midlife and older adults. The focus was on both direct associations of network structure and relationship quality with mental health, and whether these social network attributes moderated the association of self-rated health (SRH) with mental health. Analyses were based on survey data provided by 2001 (Mean age = 65, SD = 8.07) midlife and older adults. We used Latent Class Analysis (LCA) to classify participants into network types based on network structure (partner status, network size, contact frequency, and activity engagement), and used continuous measures of positive and negative social exchanges to operationalize relationship quality. Regression analysis was used to test moderation. LCA revealed network types generally consistent with those reported in previous studies. Participants in more diverse networks reported better mental health than those categorized into a restricted network type after adjustment for age, sex, education, and employment status. Analysis of moderation indicated that those with poorer SRH were less likely to report poorer mental health if they were classified into more diverse networks. A similar moderation effect was also evident for positive exchanges. The findings suggest that both quantity and quality of social relationships can play a role in buffering against the negative implications of physical health decline for mental health.

Indicators of implicit and explicit social anxiety influence threat-related interpretive bias as a function of working memory capacity

Full Text Available Interpretive biases play a crucial role in anxiety disorders. The aim of the current study was to examine factors that determine the relative strength of threat-related interpretive biases that are characteristic of individuals high in social anxiety. Different (dual process models argue that both implicit and explicit processes determine information processing biases and behaviour, and that their impact is moderated by the availability of executive resources such as working memory capacity (WMC. Based on these models, we expected indicators of implicit social anxiety to predict threat-related interpretive bias in individuals low, but not high in WMC. Indicators of explicit social anxiety should predict threat-related interpretive bias in individuals high, but not low in WMC. As expected, WMC moderated the impact of implicit social anxiety on threat-related interpretive bias, although the simple slope for individuals low in WMC was not statistically significant. The hypotheses regarding explicit social anxiety (with fear of negative evaluation used as an indicator were fully supported. The clinical implications of these findings are discussed.

Disease risk is a potential cost of group living. Although modular organization is thought to reduce this cost in animal societies, empirical evidence toward this hypothesis has been conflicting. We analyzed empirical social networks from 43 animal species to motivate our study of the epidemiological consequences of modular structure in animal societies. From these empirical studies, we identified the features of interaction patterns associated with network modularity and developed a theoretical network model to investigate when and how subdivisions in social networks influence disease dynamics. Contrary to prior work, we found that disease risk is largely unaffected by modular structure, although social networks beyond a modular threshold experience smaller disease burden and longer disease duration. Our results illustrate that the lowering of disease burden in highly modular social networks is driven by two mechanisms of modular organization: network fragmentation and subgroup cohesion. Highly fragmented social networks with cohesive subgroups are able to structurally trap infections within a few subgroups and also cause a structural delay to the spread of disease outbreaks. Finally, we show that network models incorporating modular structure are necessary only when prior knowledge suggests that interactions within the population are highly subdivided. Otherwise, null networks based on basic knowledge about group size and local contact heterogeneity may be sufficient when data-limited estimates of epidemic consequences are necessary. Overall, our work does not support the hypothesis that modular structure universally mitigates the disease impact of group living.

The factor structure of the Social Interaction Anxiety Scale and the Social Phobia Scale.

Heidenreich, Thomas; Schermelleh-Engel, Karin; Schramm, Elisabeth; Hofmann, Stefan G; Stangier, Ulrich

2011-05-01

The Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS) are two compendium measures that have become some of the most popular self-report scales of social anxiety. Despite their popularity, it remains unclear whether it is necessary to maintain two separate scales of social anxiety. The primary objective of the present study was to examine the factor analytic structure of both measures to determine the factorial validity of each scale. For this purpose, we administered both scales to 577 patients at the beginning of outpatient treatment. Analyzing both scales simultaneously, a CFA with two correlated factors showed a better fit to the data than a single factor model. An additional EFA with an oblique rotation on all 40 items using the WLSMV estimator further supported the two factor solution. These results suggest that the SIAS and SPS measure similar, but not identical facets of social anxiety. Thus, our findings provide support to retain the SIAS and SPS as two separate scales.

This paper has presented an overview of the type of optical-based structures that can be designed and constructed. These smart structures are capable of responding to their environment. The examples given represent a modest sampling of the complexity that can be achieved in both design and practice. Tamper-indicating containers and smart, sensing windows demonstrate just a few of the applications. We have shown that optical-based smart structures can be made multifunctional with the sensing built in. The next generation smart structure will combine the sensing functionality of these optical-based smart structures with other sensors such as piezoelectrics and electro-rheological fluids to not only be able to respond to the environment, but to adapt to it as well. An example of functionality in this regime would be a piezosensor that senses pressure changes (e.g., shock waves), which then causes an electro-rheological fluid to change viscosity. A fiber sensor located in or near the electro-rheological fluid senses the stiffness change and sends a signal through a feedback loop back to the piezosensor for additional adjustments to the electro-rheological fluid

Contextual factors can influence health through exposures to health-promoting and risk-inducing factors. The aim of this study was to (1) build, from geotagged Twitter and Yelp data, a national food environment database and (2) to test associations between state food environment indicators and health outcomes. This is a cross-sectional study based upon secondary analyses of publicly available data. Using Twitter's Streaming Application Programming Interface (API), we collected and processed 4,041,521 food-related, geotagged tweets between April 2015 and March 2016. Using Yelp's Search API, we collected data on 505,554 unique food-related businesses. In linear regression models, we examined associations between food environment characteristics and state-level health outcomes, controlling for state-level differences in age, percent non-Hispanic white, and median household income. A one standard deviation increase in caloric density of food tweets was related to higher all-cause mortality (+46.50 per 100,000), diabetes (+0.75%), obesity (+1.78%), high cholesterol (+1.40%), and fair/poor self-rated health (2.01%). More burger Yelp listings were related to higher prevalence of diabetes (+0.55%), obesity (1.35%), and fair/poor self-rated health (1.12%). More alcohol tweets and Yelp bars and pub listings were related to higher state-level binge drinking and heavy drinking, but lower mortality and lower percent reporting fair/poor self-rated health. Supplemental analyses with county-level social media indicators and county health outcomes resulted in finding similar but slightly attenuated associations compared to those found at the state level. Social media can be utilized to create indicators of the food environment that are associated with area-level mortality, health behaviors, and chronic conditions.

Abstract: Social behavior of white-tailed deer (Odocoileus virginianus) can have important management implications. The formation of matrilineal social groups among female deer has been documented and management strategies have been proposed based on this well-developed social structure. Using radiocollared (n = 17) and hunter or vehicle-killed (n = 21) does, we examined spatial and genetic structure in white-tailed deer on a 7,000-ha portion of the Savannah River Site in the upper Coastal Plain of South Carolina, USA. We used 14 microsatellite DNA loci to calculate pairwise relatedness among individual deer and to assign doe pairs to putative relationship categories. Linear distance and genetic relatedness were weakly correlated (r = –0.08, P = 0.058). Relationship categories differed in mean spatial distance, but only 60% of first-degree-related doe pairs (full sibling or mother–offspring pairs) and 38% of second-degree-related doe pairs (half sibling, grandmother–granddaughter pairs) were members of the same social group based on spatial association. Heavy hunting pressure in this population has created a young age structure among does, where the average age is <2.5 years, and <4% of does are >4.5 years old. This—combined with potentially elevated dispersal among young does—could limit the formation of persistent, cohesive social groups. Our results question the universal applicability of recently proposed models of spatial and genetic structuring in white-tailed deer, particularly in areas with differing harvest histories.

Electrophysiological indices of response inhibition in a Go/NoGo task predict self-control in a social context.

Directory of Open Access Journals (Sweden)

Full Text Available Recent research demonstrates that response inhibition-a core executive function-may subserve self-regulation and self-control. However, it is unclear whether response inhibition also predicts self-control in the multifaceted, high-level phenomena of social decision-making. Here we examined whether electrophysiological indices of response inhibition would predict self-control in a social context. Electroencephalography was recorded as participants completed a widely used Go/NoGo task (the cued Continuous Performance Test. Participants then interacted with a partner in an economic exchange game that requires self-control. Results demonstrated that greater NoGo-Anteriorization and larger NoGo-P300 peak amplitudes-two established electrophysiological indices of response inhibition-both predicted more self-control in this social game. These findings support continued integration of executive function and self-regulation and help extend prior research into social decision-making processes.

Similarity between community structures of different online social networks and its impact on underlying community detection

Fan, W.; Yeung, K. H.

As social networking services are popular, many people may register in more than one online social network. In this paper we study a set of users who have accounts of three online social networks: namely Foursquare, Facebook and Twitter. Community structure of this set of users may be reflected in these three online social networks. Therefore, high correlation between these reflections and the underlying community structure may be observed. In this work, community structures are detected in all three online social networks. Also, we investigate the similarity level of community structures across different networks. It is found that they show strong correlation with each other. The similarity between different networks may be helpful to find a community structure close to the underlying one. To verify this, we propose a method to increase the weights of some connections in networks. With this method, new networks are generated to assist community detection. By doing this, value of modularity can be improved and the new community structure match network's natural structure better. In this paper we also show that the detected community structures of online social networks are correlated with users' locations which are identified on Foursquare. This information may also be useful for underlying community detection.

The first objective of this study was to adapt and test the psychometric properties of the Social Achievement Goal Scale (Ryan & Shim, 2006) in Spanish adolescent students. The second objective sought to analyse the influence of social goals, normative adjustment and self-perception of social efficacy on social adjustment among peers. A total of 492 adolescents (54.1% females) attending secondary school (12-17 years; M = 13.8, SD = 1.16) participated in the study. Confirmatory factor analysis and structural equation modelling were performed. The validation confirmed the three-factor structure of the original scale: social development goals, social demonstration-approach goals and social demonstration-avoidance goals. The structural equation model indicated that social development goals and normative adjustment have a direct bearing on social adjustment, whereas the social demonstration-approach goals (popularity) and self-perception of social efficacy with peers and teachers exert an indirect influence. The Spanish version of the Social Achievement Goal Scale (Ryan & Shim, 2006) yielded optimal psychometric properties. Having a positive motivational pattern, engaging in norm-adjusted behaviours and perceiving social efficacy with peers is essential to improving the quality of interpersonal relationships.

Roosting and foraging social structure of the endangered Indiana bat (Myotis sodalis.

Directory of Open Access Journals (Sweden)

Alexander Silvis

Full Text Available Social dynamics are an important but poorly understood aspect of bat ecology. Herein we use a combination of graph theoretic and spatial approaches to describe the roost and social network characteristics and foraging associations of an Indiana bat (Myotis sodalis maternity colony in an agricultural landscape in Ohio, USA. We tracked 46 bats to 50 roosts (423 total relocations and collected 2,306 foraging locations for 40 bats during the summers of 2009 and 2010. We found the colony roosting network was highly centralized in both years and that roost and social networks differed significantly from random networks. Roost and social network structure also differed substantially between years. Social network structure appeared to be unrelated to segregation of roosts between age classes. For bats whose individual foraging ranges were calculated, many shared foraging space with at least one other bat. Compared across all possible bat dyads, 47% and 43% of the dyads showed more than expected overlap of foraging areas in 2009 and 2010 respectively. Colony roosting area differed between years, but the roosting area centroid shifted only 332 m. In contrast, whole colony foraging area use was similar between years. Random roost removal simulations suggest that Indiana bat colonies may be robust to loss of a limited number of roosts but may respond differently from year to year. Our study emphasizes the utility of graphic theoretic and spatial approaches for examining the sociality and roosting behavior of bats. Detailed knowledge of the relationships between social and spatial aspects of bat ecology could greatly increase conservation effectiveness by allowing more structured approaches to roost and habitat retention for tree-roosting, socially-aggregating bat species.

Korean immigrants don't buy health insurance: The influences of culture on self-employed Korean immigrants focusing on structure and functions of social networks.

Culture has been pinpointed as a culprit of disparities in health insurance coverage between Korean immigrants and other ethnic groups. This study explored specific mechanisms by which culture influences a decision to buy health insurance among self-employed Korean immigrants living in ethnic enclaves by focusing on the structure and functions of social networks. Between March and June 2015, we recruited 24 Korean immigrant adults (aged 18 or older) who identified as self-employed and being uninsured for substantial periods before 2014 in Southern California. Interviews were conducted in Korean, and Korean transcripts were translated into English by two bilingual interpreters. Using constant comparative analysis, we explored why participants didn't purchase health insurance after migrating to the United States and how their social networks influenced their decisions whether to purchase health insurance. Results indicate Korean immigrants sought health information from dense and homogeneous social networks whose members are mostly Korean immigrants embedded in similar social contexts. Social learning was frequently observed when people sought health care while uninsured. However, respondents often noted social ties do not provide helpful information about benefits, costs, and ways to use health insurance. "Koreans don't buy health insurance" was a dominant social norm reported by most respondents. Findings indicate that social learning and normative influence occur inside social networks and these mechanisms seemingly prevent purchasing of health insurance. In addition to the individual mandate in the Patient Protection and Affordable Care Act, more targeted approaches that consider the structure and functions of social networks could improve the public health of Korean immigrants.

Research suggests that there is a relationship between the health of urban populations and the availability of green and water spaces in their daily environment. In this paper, we analyze the potential intra-urban relationships between children's health determinants and outcomes and natural areas in Berlin, Germany. In particular, health indicators such as deficits in viso-motoric development in children are related to environmental indicators such as the natural area cover, natural area per capita and distance to natural areas; however, these indicators are also correlated with social determinants of health. The methodological approach used in this study included bivariate and multivariate analyses to explore the relations between health inequalities and social, socio-economic, and land use parameters. The results on a sub-district level indicated that there was a correlation between natural areas and social health determinants, both of which displayed a certain intra-urban spatial pattern. In particular, a lower percentage of natural area cover was correlated with deficits in viso-motoric development. However, results with percentage of natural area cover and per capita natural area with childhood overweight were not conclusive. No significant correlation was found for percentage of natural area cover and overweight, while significant negative correlation values were found between overweight and per capita natural area. This was identified particularly in the districts that had lower social conditions. On the other hand, the districts with the highest social conditions had the comparatively lowest levels of complete measles immunization. This study may facilitate public health work by identifying the urban areas in which the strengthening of health resources and actions should be prioritized and also calls for the inclusion of natural areas among the social health indicators included in intra-urban health inequality tools.

Abstract Climate change mitigation constitutes a social dilemma, a conflict between personal and collective outcomes. Behaviours that result in personal benefits (e.g. travelling quickly, conveniently and cheaply by plane) also result in a collective cost in the form of climate change. Behavioural theories and evidence suggest this social dilemma structure significantly influences behaviour. This thesis aims to understand how the social dilemma structure of climate change mitigation affect...

This investigation examined the mutual influences between structured parenting and child social wariness during toddlerhood using a longitudinal adoption design. The sample consisted of 361 adoption-linked families, each including an adopted child, adoptive parents, and a birth mother. Heightened social wariness in children at age 18 months predicted reduced levels of observed structured parenting (i.e., less directive parenting with fewer commands and requests) in adoptive mothers at age 27 months. Adoptive fathers’ lower structured parenting at age 18 months predicted subsequent elevation in child social wariness. Birth mothers’ history of fear-related anxiety disorders was not associated with child social wariness. Findings highlight the role of dynamic family transactions in the development of social wariness during toddlerhood. PMID:23448430

Elderly people, particularly those with major depression, are at the highest risk for suicide than any other age group. Religious involvement is associated with a range of health outcomes including lower odds of death by suicide. However, not much is known about the effects of religious involvement on suicidal ideation in the elderly or which aspects of religiosity are beneficial. This study examined the relative influence of various conceptualizations of religious involvement, above and beyond the protective effects of social support, on current and past suicidality among depressed older adults. Participants were 248 depressed patients, 59 years and older, enrolled in the Neurocognitive Outcomes of Depression in the Elderly study. A psychiatrist assessed current suicidal ideation using the suicidal thoughts item from the Montgomery-Asberg Depression Rating Scale. Past history of suicide attempts, four religious involvement indicators, social support indicators, and control variables were assessed via self-report. Church attendance, above and beyond importance of religion, private religious practices, and social support, was associated with less suicidal ideation; perceived social support partially mediated this relationship. Current religious practices were not predictive of retrospective reports of past suicide attempts. Church attendance, rather than other religious involvement indicators, has the strongest relationship to current suicidal ideation. Clinicians should consider public religious activity patterns and perceived social support when assessing for other known risk and protective factors for suicide and in developing treatment plans.

In this paper we analyze collected data from the web application Twitter, in order to describe the structure and dynamics of the emergent social networks, based on complexity science. We focused on a Venezuelan protest that took place exclusively by Twitter during December, 2010. We found a community structure with highly connected hubs and three different kinds of user behavior that determine the information flow dynamics. We noticed that even though online social networks appear to be a pure social environment, traditional media still holds loads of influence inside the network.

Full Text Available BACKGROUND: We study the evolutionary Prisoner's Dilemma on two social networks substrates obtained from actual relational data. METHODOLOGY/PRINCIPAL FINDINGS: We find very different cooperation levels on each of them that cannot be easily understood in terms of global statistical properties of both networks. We claim that the result can be understood at the mesoscopic scale, by studying the community structure of the networks. We explain the dependence of the cooperation level on the temptation parameter in terms of the internal structure of the communities and their interconnections. We then test our results on community-structured, specifically designed artificial networks, finding a good agreement with the observations in both real substrates. CONCLUSION: Our results support the conclusion that studies of evolutionary games on model networks and their interpretation in terms of global properties may not be sufficient to study specific, real social systems. Further, the study allows us to define new quantitative parameters that summarize the mesoscopic structure of any network. In addition, the community perspective may be helpful to interpret the origin and behavior of existing networks as well as to design structures that show resilient cooperative behavior.

Full Text Available Background and Purpose: In order to potentiate a valid comparison of forest stands, numerous indices were developed to express forest structure numerically. Each of those indices described a specific measured or calculated value. In the present study, three of the stand structure indicators, dependent on tree distance, were used: the aggregation index of Clark and Evans, the species mingling index and the diameter differentiation index. The objectives of this study were: to obtain further information about forest structure using the selected indices and to discover any limitations that the implemented indices might display. Materials and Methods: Mature pedunculate oak stands were selected as objects of the study, all located within the “Repaš – Gabajeva Greda” forest management unit, the Forest Administration of Koprivnica. The stands were aged 75 to 132 years. A systematic 500 m grid of 45 circle sample plots was established. The sample plot radius was 15, 25 or 30 meters, depending on the stand’s age. In 2001, the DBH (diameter at breast height and tree positions in regard to the centre of a plot were measured on each sample plot. The mutual distances between trees were calculated, as well as the values of the three selected stand structure indices. The two procedures of the aggregation index of Clark and Evans were calculated for all 45 sample plots. In the first case only the pedunculate oak trees were observed, and in the other all trees on the plot. The species mingling index and the diameter differentiation index were calculated for each tree in two procedures: in relatio to three and four nearest neighbouring trees. The plot/stand totals were managed as the average index of individual trees. Results: Values of the aggregation index of Clark and Evans after all trees have been observed were from 0.89 to 1.28, which indicated a random distribution of trees. In case of considering only pedunculate oak trees, the index of the plots

It has long been recognised that urban form impacts on health outcomes and their determinants. There is growing interest in creating indicators of liveability to measure progress towards achieving a wide range of policy outcomes, including enhanced health and wellbeing, and reduced inequalities. This review aimed to: 1) bring together the concepts of urban 'liveability' and social determinants of health; 2) synthesise the various liveability indicators developed to date; and 3) assess their quality using a health and wellbeing lens. Between 2011 and 2013, the research team reviewed 114 international academic and policy documents, as well as reports related to urban liveability. Overall, 233 indicators were found. Of these, 61 indicators were regarded as promising, 57 indicators needed further development, and 115 indicators were not useful for our purposes. Eleven domains of liveability were identified that likely contribute to health and wellbeing through the social determinants of health. These were: crime and safety; education; employment and income; health and social services; housing; leisure and culture; local food and other goods; natural environment; public open space; transport; and social cohesion and local democracy. Many of the indicators came from Australian sources; however most remain relevant from a 'global north' perspective. Although many indicators were identified, there was inconsistency in how these domains were measured. Few have been validated to assess their association with health and wellbeing outcomes, and little information was provided for how they should be applied to guide urban policy and practice. There is a substantial opportunity to further develop these measures to create a series of robust and evidence-based liveability indices, which could be linked with existing health and wellbeing data to better inform urban planning policies within Australia and beyond.

Eidecker, Judith; Glöckner-Rist, Angelika; Gerlach, Alexander L

2010-08-01

The Social Interaction and Anxiety Scale (SIAS) is widely used to assess social interaction anxiety. Yet its dimensional structure is still not well-defined. Especially, the conceptual pertinence of three negatively keyed items has been challenged. In this study, dimensionality of the answers of a student sample to a German SIAS version was first analyzed exploratorily. Subsequently, we tested confirmatorily several measurement models specifying different SIAS dimensions, and investigated how these relate to extraversion. The most reasonable model was cross-validated relying on data from healthy controls and social phobia sufferers. All analyses involved methods suited for an adequate handling of ordinal data. The findings confirm that three negatively keyed items are dubious indicators of social interaction anxiety. Thus, only the remaining 17 items should be used for this purpose in future studies. Analyses of their psychometric properties show, in addition, that they apparently tap three different facets of social interaction anxiety. (c) 2010 Elsevier Ltd. All rights reserved.

Previous findings suggest that social anxiety disorder may be best characterized as having a dimensional latent structure (Kollman et al., 2006; Weeks et al., 2009). We attempted to extend previous taxometric investigations of social anxiety by examining the latent structure of social anxiety disorder symptoms in a large sample comprised of social anxiety disorder patients (i.e., putative taxon members) and community residents/undergraduate respondents (i.e., putative complement class members). MAXEIG and MAMBAC were performed with indicator sets drawn from a self-report measure of social anxiety symptoms, the Social Interaction Phobia Scale (Carleton et al., 2009). MAXEIG and MAMBAC analyses, as well as comparison analyses utilizing simulated taxonic and dimensional datasets, yielded converging evidence that social anxiety disorder has a taxonic latent structure. Moreover, 100% of the confirmed social anxiety disorder patients in our overall sample were correctly assigned to the identified taxon class, providing strong support for the external validity of the identified taxon; and k-means cluster analysis results corroborated our taxometric base-rate estimates. Implications regarding the conceptualization, diagnosis, and assessment of social anxiety disorder are discussed. Copyright 2010 Elsevier Ltd. All rights reserved.

Few studies have assessed healthcare experiences in apparently healthy adolescents, or whether healthcare attitudes are linked to the two leading adolescent health indicators, smoking and obesity. Even fewer have examined these relationships in adolescent immigrant groups or made comparisons to adolescent non-immigrants. Using a cross-sectional study, healthcare experiences were compared among three groups of adolescents (n = 589) including Russian immigrants (n = 154), Ethiopian immigrants (n = 54), and non-immigrants (n = 381). Bootstrap estimates indicated positive healthcare experiences were less common among Russian adolescent immigrants (OR = 0.38, CI = 0.17, 0.86) compared to non-immigrants, unless the Russian adolescent immigrants reported above average socioeconomic status, in which case they were more likely than non-immigrant adolescents to report positive healthcare experiences (OR = 3.22, CI = 1.05, 9.85). Positive healthcare experiences were less likely among adolescents who were smokers (OR = 0.50, CI = 0.27, 0.91), and more likely for adolescents with a normal or low BMI (OR = 3.16, CI = 1.56, 6.40) and for those relying on parents for health information (OR = 1.97, CI = 1.05, 3.70). Findings suggest a social gradient in which positive healthcare experiences were more common among adolescence with higher socioeconomic status for some immigrants (Russian adolescents) but not for others. The two leading health indicators were related to healthcare experiences, but as adolescent smokers were less likely to have positive healthcare experiences, proactive efforts are needed to engage this group. What is Known: • Health indicators (such as obesity) and healthcare attitudes are linked to healthcare service use among adolescents sampled from outpatient and inpatient populations. What is New: • A social gradient involving socioeconomic status and being an adolescent immigrant was found regarding

A financial market is a complex system consisting of many interacting units. In general, due to the various types of information exchange within the industry, there is a relationship between the stocks that can reveal their clear structural characteristics. Complex network methods are powerful tools for studying the internal structure and function of the stock market, which allows us to better understand the stock market. Applying complex network methodology, a stock associated network model based on financial indicators is created. Accordingly, we set threshold value and use modularity to detect the community network, and we analyze the network structure and community cluster characteristics of different threshold situations. The study finds that the threshold value of 0.7 is the abrupt change point of the network. At the same time, as the threshold value increases, the independence of the community strengthens. This study provides a method of researching stock market based on the financial indicators, exploring the structural similarity of financial indicators of stocks. Also, it provides guidance for investment and corporate financial management.

Social vaccines to resist and change unhealthy social and economic structures: a useful metaphor for health promotion.

Science.gov (United States)

Baum, Fran; Narayan, Ravi; Sanders, David; Patel, Vikram; Quizhpe, Arturo

2009-12-01

The term 'social vaccine' is designed to encourage the biomedically orientated health sector to recognize the legitimacy of action on the distal social and economic determinants of health. It is proposed as a term to assist the health promotion movement in arguing for a social view of health which is so often counter to medical and popular conceptions of health. The idea of a social vaccine builds on a long tradition in social medicine as well as on a biomedical tradition of preventing illness through vaccines that protect against disease. Social vaccines would be promoted as a means to encourage popular mobilization and advocacy to change the social and economic structural conditions that render people and communities vulnerable to disease. They would facilitate social and political processes that develop popular and political will to protect and promote health through action (especially governments prepared to intervene and regulate to protect community health) on the social and economic determinants. Examples provided for the effects of social vaccines are: restoring land ownership to Indigenous peoples, regulating the advertising of harmful products and progressive taxation for universal social protection. Social vaccines require more research to improve understanding of social and political processes that are likely to improve health equity worldwide. The vaccine metaphor should be helpful in arguing for increased action on the social determinants of health.

Scale-Free Relationships between Social and Landscape Factors in Urban Systems

Directory of Open Access Journals (Sweden)

Chunzhu Wei

2017-01-01

Full Text Available Urban planners and ecologists have long debated the relationship between the structure of urban landscapes and social activities. There have, however, been very few discussions as to whether any such relationships might depend on the scales of observation. This work applies a hierarchical zoning technique to data from the city of Quito, Ecuador, to examine how relationships between typical spatial landscape metrics and social indicators depend on zoning scales. Our results showed that the estimates of both landscape heterogeneity features and social indicators significantly depend on the zoning scale. The mean values of the typical landscape metrics and the social indicators all exhibited predictable responses to a changing zoning scale, suggesting a consistent and significant scaling relationship within the multiple zoning scales. Yet relationships between these pairs of variables remain notably invariant to scale. This quantitative demonstration of the scale-free nature of the relationship between landscape characteristics and social indicators furthers our understanding of the relationships between landscape structures and social aspects of urban spaces, including deprivation and public service accessibility. The relationships between social indicators and one typical landscape aggregation metric (represented as the percentage of like adjacencies were nevertheless significantly dependent on scale, suggesting the importance of zoning scale decisions for analyzing the relationships between the social indicators and the landscape characteristics related with landscape adjacency. Aside from this typical landscape aggregation metric, the general invariance to the zoning scale of relationships between landscape structures and socioeconomic indicators in Quito suggests the importance of applying these scale-free relationships in understanding complex socio-ecological systems in other cities, which are shaped by the conflated influences of both

Dynamical Structure of a Traditional Amazonian Social Network

Paul L. Hooper

2013-11-01

Full Text Available Reciprocity is a vital feature of social networks, but relatively little is known about its temporal structure or the mechanisms underlying its persistence in real world behavior. In pursuit of these two questions, we study the stationary and dynamical signals of reciprocity in a network of manioc beer (Spanish: chicha; Tsimane’: shocdye’ drinking events in a Tsimane’ village in lowland Bolivia. At the stationary level, our analysis reveals that social exchange within the community is heterogeneously patterned according to kinship and spatial proximity. A positive relationship between the frequencies at which two families host each other, controlling for kinship and proximity, provides evidence for stationary reciprocity. Our analysis of the dynamical structure of this network presents a novel method for the study of conditional, or non-stationary, reciprocity effects. We find evidence that short-timescale reciprocity (within three days is present among non- and distant-kin pairs; conversely, we find that levels of cooperation among close kin can be accounted for on the stationary hypothesis alone.

Childhood adversity (CA) is associated with problem behaviors in adolescence, but the mediators, that is, those factors that help build resilience and prevent some children who experience CA from engaging in problem behaviors, await more exploration, including social integration. The aim of this study was to identify the association between CA and adolescent problem behaviors, and to further examine the mediating role of social integration distinctly as psychological and structural integration. Data used were from the Taiwan Education Panel Survey, a core panel of 4,261 students (age 13) surveyed in 2001 and followed for three more waves until age 18. For psychological integration, an average score was calculated to represent adolescents' feelings about their school. Structural integration was constructed using several items about adolescents' school and extracurricular activities. We used structural equation modeling with the diagonally weighted least squares method to examine the effect of CA on the primary outcome: adolescent problem behaviors via social integration. The hypothesized structural equation model specifying the path from CA to adolescent problem behavior had good fit. Respondents with one CA were indirectly linked to problem behaviors via psychological but not structural integration (e.g. the level of participation in school and non-school activities). On mediation analysis, psychological integration significantly mediated the paths from one CA to all six problem behaviors (all P integration; two or more CA were not associated with significant paths to problem behaviors. The contribution of social integration is crucial to an adolescent's development from CA to problem behaviors. To form supportive social relationships to achieve better health, we suggest that those adolescents who have been exposed to CA should be helped to join more teams and take part in more activities, thereby increasing their opportunities for social interaction, and improving

Social relationship difficulties in autism and reactive attachment disorder: Improving diagnostic validity through structured assessment.

Autism Spectrum Disorder (ASD) versus Reactive Attachment Disorder (RAD) is a common diagnostic challenge for clinicians due to overlapping difficulties with social relationships. RAD is associated with neglect or maltreatment whereas ASD is not: accurate differential diagnosis is therefore critical. Very little research has investigated the relationship between the two, and it is unknown if standardised measures are able to discriminate between ASD and RAD. The current study aimed to address these issues. Fifty eight children with ASD, and no history of maltreatment, were group matched on age with 67 children with RAD. Group profiles on multi-informant measures of RAD were investigated and group differences explored. Discriminant function analysis determined assessment features that best discriminated between the two groups. Although, according to parent report, children with ASD presented with significantly fewer indiscriminate friendliness behaviours compared to the RAD group (p<0.001), 36 children with ASD appeared to meet core RAD criteria. However, structured observation clearly demonstrated that features were indicative of ASD and not RAD for all but 1 of these 36 children. Children with RAD and children with ASD may demonstrate similar social relationship difficulties but there appears to be a difference in the social quality of the interactions between the groups. In most cases it was possible to differentiate between children with ASD and children with RAD via structured observation. Nevertheless, for a small proportion of children with ASD, particularly those whose difficulties may be more subtle, our current standardised measures, including structured observation, may not be effective in differentiating RAD from ASD.

Shiovitz-Ezra, Sharon; Leitsch, Sara; Graber, Jessica; Karraker, Amelia

2009-11-01

The National Social Life, Health, and Aging Project (NSHAP) measures seven indicators of quality of life (QoL) and psychological health. The measures used for happiness, self-esteem, depression, and loneliness are well established in the literature. Conversely, measures of anxiety, stress, and self-reported emotional health were modified for their use in this unique project. The purpose of this paper is to provide (a) an overview of NSHAP's QoL assessment and (b) evidence for the adequacy of the modified measures. First, we examined the psychometric properties of the modified measures. Second, the established QoL measures were used to examine the concurrent validity of the modified measures. Finally, gender- and age-group differences were examined for each modified measure. The anxiety index exhibited good internal reliability and concurrent validity. Consistent with the literature, a single-factor structure best fit the data. Stress was satisfactory in terms of concurrent validity but with only fair internal consistency. Self-reported emotional health exhibited good concurrent validity and moderate external validity. The modified indices used in NSHAP tended to exhibit good internal reliability and concurrent validity. These measures can confidently be used in the exploration of QoL and psychological health in later life and its many correlates.

The mutual extraction industry: drug use and the normative structure of social capital in the Russian far north.

Science.gov (United States)

Pilkington, Hilary; Sharifullina, El'vira

2009-05-01

The article contributes to the literature on the role of social networks and social capital in young people's drug use. It considers the structural and cultural dimensions of the 'risk environment' of post-Soviet Russia, the micro risk-environment of a de-industrializing city in the far north of the country and the kind of social capital that circulates in young people's social networks there. Its focus is thus on social capital at the micro-level, the 'bridging' networks of peer friendship groups and the norms that govern them. The research is based on a small ethnographic study of the friendship groups and social networks of young people in the city of Vorkuta in 2006-2007. It draws on data from 32 respondents aged 17-27 in the form of 17 semi-structured audio and video interviews and field diaries. Respondents were selected from friendship groups in which drug use was a regular and symbolically significant practice. The risk environment of the Russian far north is characterised by major de-industrialization, poor health indicators, low life expectancy and limited educational and employment opportunities. It is also marked by a 'work hard, play hard' cultural ethos inherited from the Soviet period when risk-laden manual labour was well-rewarded materially and symbolically. However, young people today often rely on informal economic practices to generate the resource needed to fulfil their expectations. This is evident from the social networks among respondents which were found to be focused around a daily routine of generating and spending income, central to which is the purchase, sale and use of drugs. These practices are governed by norms that often invert those normally ascribed to social networks: reciprocity is replaced by mutual exploitation and trust by cheating. Social networks are central to young people's management of the risk environment associated with post-Soviet economic transformation. However, such networks are culturally as well as structurally

Social-emotional behavior of 352 3- and 4-year-olds attending private child-care and Head Start programs was observed using the Minnesota Preschool Affect Checklist, Revised (MPAC-R). Goals of the investigation included (a) using MPAC-R data to extract a shortened version, MPAC-R/S, comparing structure, internal consistency, test-retest reliability, and stability of both versions; and, using the shortened measure, to examine (b) age, gender, and risk status differences in social-emotional behaviors; (c) contributions of emotion knowledge and executive function to social-emotional behaviors; and (d) contributions of social-emotional behaviors to early school adjustment and kindergarten academic success. Results show that reliability of MPAC-R/S was as good, or better, than the MPAC-R. MPAC-R/S structure, at both times of observation, included emotionally negative/aggressive, emotionally regulated/prosocial, and emotionally positive/productive behaviors; MPAC-R structure was similar but less replicable over time. Age, gender, and risk differences were found. Children's emotion knowledge contributed to later emotionally regulated/prosocial behavior. Finally, preschool emotionally negative/aggressive behaviors were associated with concurrent and kindergarten school success, and there was evidence of social-emotional behavior mediating relations between emotion knowledge or executive function, and school outcomes. The importance of portable, empirically supported observation measures of social-emotional behaviors is discussed along with possible applications, teacher utilization, and implementation barriers.

Designing a socio-spatial need indicator for urban social services analysis and decision making. A case study

Antonio Morenos Jiménez

2015-01-01

Full Text Available Decision taking on social services requires, as a previous step, to appraise the human needs and their spatial distribution, a key issue particularly sensitive in less developed zones or during economic crisis periods, as far as socio-spatial cohesion is then strongly challenged. Vari-ous methods have been used for measuring social needs, provided that these are diverse in nature and sometimes elusive. Incorporating the spatial dimension in this task involves an additional challenge, but the results add meaningful value for socio-spatial planning. Along this concern, in this work it is tackled the problema of estimating the needs typically met by local social service centers (SSC. To this end, it is designed a novel statistical indicator for intra-urban zones, incorporating in the formula the main components of the actual observed de-mand as well as the per capita income, to take into account the relevant spatial equity principle. Using a geographical information systems (GIS, the indicator for estimating SSC need has been experimentally obtained for two types of spatial units in the city of Madrid: municipal districts and small statistical areas, looking for complementary applied uses. The results reveal the intra-urban inequalities for these types of needs and may support public decision making on spatial provision and location of this kind of social resources. In addition, a preliminary and statistically based exam of the indicator potentialities and limitations is carried out for both types of spatial units.

Social media has become increasingly important over the past decades and has been integrated in various environments, including the healthcare setting. Yet, the influence of social media use on the social skills and nurse-patient interaction of nurses is an area in nursing that requires further studies. This study determined the interrelationships among social media use profile, social skills, and nurse-patient interaction of Registered Nurses in tertiary hospitals. Employing structural equation modeling, a descriptive-correlational study was conducted among 212 consecutively-selected nurses from two tertiary hospitals. Consenting respondents completed a two-part survey composed of the respondent profile sheet and the Social Skills Inventory. The respondent profile sheet assessed demographic profile and social media use profile in terms of the mode, frequency, and duration of utilization. Three trained team members observed each nurse-patient dyad and completed the Nurse-Patient Bonding Instrument. A good fit model illustrated the negative effects of frequent social media use to patient openness (β = -0.18, p social media on a daily basis, however, positively affected both dimensions of social skills. Accessing social media platforms using non-handheld devices showed the most influential positive effects to social skills and nurse-patient interaction. Additionally, although verbal social skills positively affected most dimensions of nurse-patient interaction, non-verbal social skills negatively influenced patient engagement (β = -0.19, p = 0.019) and nurse openness (β = -0.38, p ≤ 0.05). The structural model illustrates the effects of using social media on the social skills and nurse-patient interaction of nurses and emphasizes the need for implementing institutional policies on the judicious use and application of social media in the workplace. Further, social skills development programs geared toward having a balanced social skill must

Quasistatic Seismic Damage Indicators for RC Structures from Dissipating Energies in Tangential Subspaces

Directory of Open Access Journals (Sweden)

Wilfried B. Krätzig

2014-01-01

Full Text Available This paper applies recent research on structural damage description to earthquake-resistant design concepts. Based on the primary design aim of life safety, this work adopts the necessity of additional protection aims for property, installation, and equipment. This requires the definition of damage indicators, which are able to quantify the arising structural damage. As in present design, it applies nonlinear quasistatic (pushover concepts due to code provisions as simplified dynamic design tools. Substituting so nonlinear time-history analyses, seismic low-cycle fatigue of RC structures is approximated in similar manner. The treatment will be embedded into a finite element environment, and the tangential stiffness matrix KT in tangential subspaces then is identified as the most general entry for structural damage information. Its spectra of eigenvalues λi or natural frequencies ωi of the structure serve to derive damage indicators Di, applicable to quasistatic evaluation of seismic damage. Because det KT=0 denotes structural failure, such damage indicators range from virgin situation Di=0 to failure Di=1 and thus correspond with Fema proposals on performance-based seismic design. Finally, the developed concept is checked by reanalyses of two experimentally investigated RC frames.

Recent research on social contagion has demonstrated significant effects of network topology on the dynamics of diffusion. However, network topologies are not given a priori. Rather, they are patterns of relations that emerge from individual and structural features of society, such as population composition, group heterogeneity, homophily, and social consolidation. Following Blau and Schwartz, the author develops a model of social network formation that explores how social and structural constraints on tie formation generate emergent social topologies and then explores the effectiveness of these social networks for the dynamics of social diffusion. Results show that, at one extreme, high levels of consolidation can create highly balkanized communities with poor integration of shared norms and practices. As suggested by Blau and Schwartz, reducing consolidation creates more crosscutting circles and significantly improves the dynamics of social diffusion across the population. However, the author finds that further reducing consolidation creates highly intersecting social networks that fail to support the widespread diffusion of norms and practices, indicating that successful social diffusion can depend on moderate to high levels of structural consolidation.

Social barriers have been shown to reduce gene flow and contribute to genetic structure among populations in species with high cognitive capacity and complex societies, such as cetaceans, apes and humans. In birds, high dispersal capacity is thought to prevent population divergence unless major geographical or habitat barriers induce isolation patterns by dispersal, colonization or adaptation limitation. We report that Iberian populations of the red-billed chough, a social, gregarious corvid with high dispersal capacity, show a striking degree of genetic structure composed of at least 15 distinct genetic units. Monitoring of marked individuals over 30 years revealed that long-distance movements over hundreds of kilometres are common, yet recruitment into breeding populations is infrequent and highly philopatric. Genetic differentiation is weakly related to geographical distance, and habitat types used are overall qualitatively similar among regions and regularly shared by individuals of different populations, so that genetic structure is unlikely to be due solely to isolation by distance or isolation by adaptation. Moreover, most population nuclei showed relatively high levels of genetic diversity, suggesting a limited role for genetic drift in significantly differentiating populations. We propose that social mechanisms may underlie this unprecedented level of genetic structure in birds through a pattern of isolation by social barriers not yet described, which may have driven this remarkable population divergence in the absence of geographical and environmental barriers. © 2017 John Wiley & Sons Ltd.

We study the multifractal nature of daily price and volatility returns of Latin-American stock markets employing the multifractal detrended fluctuation analysis. Comparing with the results obtained for a developed country (US) we conclude that the multifractality degree is higher for emerging markets. Moreover, we propose a stock market inefficiency ranking by considering the multifractality degree as a measure of inefficiency. Finally, we analyze the sources of multifractality quantifying the contributions of two factors, the long-range correlations of the time series and the broad fat-tail distributions. We find that the multifractal structure of Latin-American market indices can be mainly attributed to the latter.

2010-10-01

Full Text Available Abstract Background Scientific research has provided evidence on benefits of well developed primary care systems. The relevance of some of this research for the European situation is limited. There is currently a lack of up to date comprehensive and comparable information on variation in development of primary care, and a lack of knowledge of structures and strategies conducive to strengthening primary care in Europe. The EC funded project Primary Health Care Activity Monitor for Europe (PHAMEU aims to fill this gap by developing a Primary Care Monitoring System (PC Monitor for application in 31 European countries. This article describes the development of the indicators of the PC Monitor, which will make it possible to create an alternative model for holistic analyses of primary care. Methods A systematic review of the primary care literature published between 2003 and July 2008 was carried out. This resulted in an overview of: (1 the dimensions of primary care and their relevance to outcomes at (primary health system level; (2 essential features per dimension; (3 applied indicators to measure the features of primary care dimensions. The indicators were evaluated by the project team against criteria of relevance, precision, flexibility, and discriminating power. The resulting indicator set was evaluated on its suitability for Europe-wide comparison of primary care systems by a panel of primary care experts from various European countries (representing a variety of primary care systems. Results The developed PC Monitor approaches primary care in Europe as a multidimensional concept. It describes the key dimensions of primary care systems at three levels: structure, process, and outcome level. On structure level, it includes indicators for governance, economic conditions, and workforce development. On process level, indicators describe access, comprehensiveness, continuity, and coordination of primary care services. On outcome level, indicators

Full Text Available In this article attention is focused on social responsibility of business and on necessity to estimate its condition in Ukraine. Materials regarding elements and the principles of corporate social responsibility are structured. On this basis unification of quantitative elements of business social responsibility is offered according to which it is possible to carry out the analysis of the non­financial reporting. It is proposed to use not only quantitative techniques of data analysis but also refer to the qualitative ones. As a result of this, the analysis of social reports will be more productive and would minimize subjectivity of the researcher or representatives of the company which are responsible for presenting the information to the general public. The basic principles by which the companies can realize the strategy of corporate social responsibility are considered. Due to the empirical analysis of corporate reports expediency to use specified elements is proved. Reports of the companies in producing and non­productive sector are analyzed in more detail; features of displaying information on corporate social responsibility are defined. The attention to need of carrying out monitoring researches in the sphere of the corporate social reporting is updated.

The Sociological Study of the Effect of Family Structure on Social Health of Males

Naima Mohammadi

Full Text Available Social health depends on different social and cultural factors. One of the most important suppliers of individual’s health is family structures and relations. In recent years due to functional changes in polygamous structure, there are threats against social health of men in Sarbaz city. In this research, to compare the rate of social health of men in polygamous and monogamous families in Sarbaz city we use a standard questionnaire of Shapiro & Keyes (2007. The population of this study consisted of 300 males who are residents of this city. They selected by using cluster sampling method. Gathered data were analyzed using SPSS software version 22. Findings from independent T-Test revealed that the average of social Coherence, Integration, Contribution and Actualization between men in polygamous families were significantly lower than monogamous. Based on these findings, we can conclude however a lot of traditional social customs were useful, functional and compatible and provide social acceptance, but today have become dysfunctional and threated social health of family members and community system face with crisis.

A Capability Approach to Understanding Sport for Social Inclusion: Agency, Structure and Organisations

Directory of Open Access Journals (Sweden)

Naofumi Suzuki

2017-06-01

Full Text Available Despite the global diffusion of the term social inclusion, as well as the use of sport to promote it, questions have been raised regarding the extent to which sport is able to contribute to transforming the exclusive nature of the social structure. The lack of analytical clarity of the concept has not helped to address these questions. This article proposes a conceptual framework based on Amartya Sen’s capability approach, considering social exclusion as the denial of social relations that leads to serious deprivation of important capabilities. A person’s capabilities could potentially be improved through micro-, meso-, and macro-level social processes. At the micro level, sport-based social inclusion programmes could offer such social relations to varying degrees, though sport’s values are only relative to other leisure activities. The scale of impact depends primarily on the meso-level processes, in which the size and quality of each programme can be improved through organisational learning, and secondarily on the macro-level processes whereby the organisational population is institutionalised. It is argued that more research needs to be done on the meso and macro levels, as they are concerned with the ultimate potential of sport to facilitate structural transformation towards more socially inclusive society.

This work is aimed at describing the workflow for a methodology that combines chemoinformatics and pharmacoepidemiology methods and at reporting the first predictive model developed with this methodology. The new model is able to predict complex networks of AIDS prevalence in the US counties, taking into consideration the social determinants and activity/structure of anti-HIV drugs in preclinical assays. We trained different Artificial Neural Networks (ANNs) using as input information indices of social networks and molecular graphs. We used a Shannon information index based on the Gini coefficient to quantify the effect of income inequality in the social network. We obtained the data on AIDS prevalence and the Gini coefficient from the AIDSVu database of Emory University. We also used the Balaban information indices to quantify changes in the chemical structure of anti-HIV drugs. We obtained the data on anti-HIV drug activity and structure (SMILE codes) from the ChEMBL database. Last, we used Box-Jenkins moving average operators to quantify information about the deviations of drugs with respect to data subsets of reference (targets, organisms, experimental parameters, protocols). The best model found was a Linear Neural Network (LNN) with values of Accuracy, Specificity, and Sensitivity above 0.76 and AUROC > 0.80 in training and external validation series. This model generates a complex network of AIDS prevalence in the US at county level with respect to the preclinical activity of anti-HIV drugs in preclinical assays. To train/validate the model and predict the complex network we needed to analyze 43,249 data points including values of AIDS prevalence in 2,310 counties in the US vs ChEMBL results for 21,582 unique drugs, 9 viral or human protein targets, 4,856 protocols, and 10 possible experimental measures.

Social media have been widely used to organize citizen movements. In 2012, 75% university and college students in Quebec, Canada, participated in mass protests against an increase in tuition fees, mainly organized using social media. To reduce public disruption, the government introduced special legislation designed to impede protest organization. Here, we show that the legislation changed the behaviour of social media users but not the overall structure of their social network on Twitter. Th...

EDITORIAL: Sensitive structures: refractive indices in nanotechnology Sensitive structures: refractive indices in nanotechnology

Science.gov (United States)

Demming, Anna

2012-12-01

Refractive index effects using nanoscale systems are frequently applied in new imaging, sensing and even visibility cloaking technology. In this issue, researchers in Japan use simulations and experiments to describe the confinement of optical vortices in nanoscale fin structures and the sensitivity of these systems to the refractive index of the surrounding media [1]. The effects of refraction as light rays pass between different media were recorded as long ago as the first century AD, by Ptolemy [2]. Over the following centuries the phenomena inspired Ibn Sahl in 984 [3], Thomas Harriot in 1602 [4], Willebrord Snellius in 1621 [5] and Rene Descartes in 1637 [6] to independently derive the more accurate and elegant equation for refraction so familiar to us today. Recent studies of the interactions between light and matter continue to reveal a wealth of phenomena that originate in the effects of the refractive indices of materials. Nanostructures can be used to manipulate conditions that affect the refractive indices of materials, such as temperature. A E Aliev et al at the University of Texas reported a striking demonstration of temperature-dependent refractive index effects using a free-standing, highly aligned carbon nanotube aerogel sheet [7]. They used the extremely low thermal capacitance and high heat transfer ability of transparent carbon nanotube sheets to enable high-frequency modulation of the sheet temperature over an enormous temperature range. The resulting sharp, rapidly changing gradient of the refractive index in the surrounding liquid or gas makes objects seem to disappear and can be used for visibility cloaking. Light-matter interaction resonances, where light is confined at the nanoscale, can be extremely sensitive to changes in the refractive index of the surrounding media [8], even allowing single-molecule detection [9]. Plasmons, the collective oscillations of electrons in response to incident light, are a typical example. Researchers at Rice

Finding Community Structures In Social Activity Data

KAUST Repository

Peng, Chengbin

2015-05-19

Social activity data sets are increasing in number and volume. Finding community structure in such data is valuable in many applications. For example, understand- ing the community structure of social networks may reduce the spread of epidemics or boost advertising revenue; discovering partitions in tra c networks can help to optimize routing and to reduce congestion; finding a group of users with common interests can allow a system to recommend useful items. Among many aspects, qual- ity of inference and e ciency in finding community structures in such data sets are of paramount concern. In this thesis, we propose several approaches to improve com- munity detection in these aspects. The first approach utilizes the concept of K-cores to reduce the size of the problem. The K-core of a graph is the largest subgraph within which each node has at least K connections. We propose a framework that accelerates community detection. It first applies a traditional algorithm that is relatively slow to the K-core, and then uses a fast heuristic to infer community labels for the remaining nodes. The second approach is to scale the algorithm to multi-processor systems. We de- vise a scalable community detection algorithm for large networks based on stochastic block models. It is an alternating iterative algorithm using a maximum likelihood ap- proach. Compared with traditional inference algorithms for stochastic block models, our algorithm can scale to large networks and run on multi-processor systems. The time complexity is linear in the number of edges of the input network. The third approach is to improve the quality. We propose a framework for non- negative matrix factorization that allows the imposition of linear or approximately linear constraints on each factor. An example of the applications is to find community structures in bipartite networks, which is useful in recommender systems. Our algorithms are compared with the results in recent papers and their quality and e

Although people and events that disconfirm observers' expectancies can increase their creativity, sometimes such social schema violations increase observers' rigidity of thought and undermine creative cognition. Here we examined whether individual differences in the extent to which people prefer structure and predictability determine whether social schema violations facilitate or hamper creativity. Participants in Study 1 formed impressions of a schema-inconsistent female mechanic (vs. a schema-consistent male mechanic). Following schema-inconsistent rather than -consistent information, participants low (high) in need for structure showed better (impeded) creative performance. Participants in Study 2 memorized a series of images in which individuals were placed on a schema-inconsistent (vs. consistent) background (e.g., an Eskimo on the desert vs. on a snowy landscape). Following schema-inconsistent imagery, participants low (high) in need for structure increased (decreased) divergent thinking. © 2014 by the Society for Personality and Social Psychology, Inc.

Social lives have shifted, at least in part, for large portions of the population to social networking sites. How such lifestyle changes may be associated with brain structures is still largely unknown. In this manuscript, we describe two preliminary studies aimed at exploring this issue. The first study (n = 276) showed that Facebook users reported on increased social-semantic and mentalizing demands, and that such increases were positively associated with people's level of Facebook use. The second study (n = 33) theorized on and examined likely anatomical correlates of such changes in demands on the brain. Findings indicated that the grey matter volumes of the posterior parts of the bilateral middle and superior temporal, and left fusiform gyri were positively associated with the level of Facebook use. These results provided preliminary evidence that grey matter volumes of brain structures involved in social-semantic and mentalizing tasks may be linked to the extent of social networking sites use.

Emergence of scale-free close-knit friendship structure in online social networks.

Directory of Open Access Journals (Sweden)

Ai-Xiang Cui

Full Text Available Although the structural properties of online social networks have attracted much attention, the properties of the close-knit friendship structures remain an important question. Here, we mainly focus on how these mesoscale structures are affected by the local and global structural properties. Analyzing the data of four large-scale online social networks reveals several common structural properties. It is found that not only the local structures given by the indegree, outdegree, and reciprocal degree distributions follow a similar scaling behavior, the mesoscale structures represented by the distributions of close-knit friendship structures also exhibit a similar scaling law. The degree correlation is very weak over a wide range of the degrees. We propose a simple directed network model that captures the observed properties. The model incorporates two mechanisms: reciprocation and preferential attachment. Through rate equation analysis of our model, the local-scale and mesoscale structural properties are derived. In the local-scale, the same scaling behavior of indegree and outdegree distributions stems from indegree and outdegree of nodes both growing as the same function of the introduction time, and the reciprocal degree distribution also shows the same power-law due to the linear relationship between the reciprocal degree and in/outdegree of nodes. In the mesoscale, the distributions of four closed triples representing close-knit friendship structures are found to exhibit identical power-laws, a behavior attributed to the negligible degree correlations. Intriguingly, all the power-law exponents of the distributions in the local-scale and mesoscale depend only on one global parameter, the mean in/outdegree, while both the mean in/outdegree and the reciprocity together determine the ratio of the reciprocal degree of a node to its in/outdegree. Structural properties of numerical simulated networks are analyzed and compared with each of the four

This study aimed to develop effectiveness indicators for social marketing communication to reduce health-risk behaviors among Thai youth by using the Delphi technique. The Delphi technique is a research approach used to gain consensus through a series of two or more rounds of questionnaire surveys where information and results are fed back to panel members between each round and it has been extensively used to generate many indicators relevant to health behaviors. The Delphi technique was conducted in 3 rounds by consulting a panel of 15 experts in the field of social marketing communication for public health campaigns in Thailand. We found forty-nine effectiveness indicators in eight core components reached consensus. These components were: 1) attitude about health-risk behavior reduction, 2) subjective norms, 3) perceived behavioral control, 4) intention to reduce health-risk behaviors, 5) practices for reducing health-risk behaviors, 6) knowledge about the dangers and impact of health-risk behaviors, 7) campaign brand equity, and 8) communication networks. These effectiveness indicators could be applied by health promotion organizations for evaluating the effectiveness of social marketing communication to effectively reduce health-risk behaviors among youth.

New proposals are attended with a new set of role-expectation. If we lack attention to this aspect of any proposal, we face a serious difficulty in its implementation stage. The system called as Public Hearring shows us this fact. In this paper, introducing ABC model of communication by Westley and Maclean, we try to describe a set of role-expectation for particitants in social planning systems. And also introducing analytical concepts of role enactment process, we reveal two important problems for any proposal as a subsystem of social planning systems: (i) importance of role negotiation process for role-consensus, and (ii) necessity of supporting systems for role-adaptation. Especially for role-adaptation to Channel-Roles, we indicate the potential of VISMS as its supporting system. (author)

This paper discusses the social science and engineering dimensions of search and rescue (SAR) in collapsed buildings. First, existing information is presented on factors that influence the behaviour of trapped victims, particularly human, physical, socioeconomic and circumstantial factors. Trapped victims are most often discussed in the context of structural collapse and injuries sustained. Most studies in this area focus on earthquakes as the type of disaster that produces the most extensive structural damage. Second, information is set out on the engineering aspects of urban search and rescue (USAR) in the United States, including the role of structural engineers in USAR operations, training and certification of structural specialists, and safety and general procedures. The use of computational simulation to link the engineering and social science aspects of USAR is discussed. This could supplement training of local SAR groups and USAR teams, allowing them to understand better the collapse process and how voids form in a rubble pile. A preliminary simulation tool developed for this purpose is described. © 2010 The Author(s). Journal compilation © Overseas Development Institute, 2010.

Agency and the reproduction of social structures: On the example of the rotation system of work in Bashkortostan

Directory of Open Access Journals (Sweden)

2016-12-01

Full Text Available The article considers the way of life, lifestyle and positions in the labor market of shift workers from rural areas of the Republic Bashkortostan. This social group is rather large and specific to the Volga Federal District of Russia. Its distinctive features are mobile employment and regular pendulum migration. The key aim of the study was to analyze the agency and the reproduction of social structures in the sphere of the long-distance rotation system, the position and roles of shift workers in the social life of the Russian region. The community of shift workers is considered as a social space of positions (external social structures in the sphere of employment, and as a social space of their way of life and individual characteristics (lifestyle, cultural capital and habitus. The interaction within the social space of the long-distance shift positions, mode of life and lifestyle of shift workers is based on the principle of the structure “duality” that opposes and contradicts the principle of structural “dualism”. The paper reveals differences between two principles in the context of structuration theory, constructivist structuralism and critical realism. The methodology of the analysis of shift workers’ labor participation and everyday activities is based on the idea of the duality of structure. The labor career and rural mode of life of shift workers are determined by structural and institutional conditions that limit their behavior in the reproduction of social structures. The lifestyle of shift workers is determined by a relatively free choice of leisure activities during their stay at home in rural areas and characterizes their agency. The selectivity of their leisure practices is reflected in the well-established lifestyle, which depends on the limitations in the social sphere of rural life and their mode of life at work («vakhta». The reproduction of shift workers labor positions hierarchy in the social space is provided

Contemporary humans exhibit spectacular biological success derived from cumulative culture and cooperation. The origins of these traits may be related to our ancestral group structure. Because humans lived as foragers for 95% of our species' history, we analyzed co-residence patterns among 32 present-day foraging societies (total n = 5067 individuals, mean experienced band size = 28.2 adults). We found that hunter-gatherers display a unique social structure where (i) either sex may disperse or remain in their natal group, (ii) adult brothers and sisters often co-reside, and (iii) most individuals in residential groups are genetically unrelated. These patterns produce large interaction networks of unrelated adults and suggest that inclusive fitness cannot explain extensive cooperation in hunter-gatherer bands. However, large social networks may help to explain why humans evolved capacities for social learning that resulted in cumulative culture.

A social network analysis of social cohesion in a constructed pride: implications for ex situ reintroduction of the African lion (Panthera leo.

Full Text Available Animal conservation practices include the grouping of captive related and unrelated individuals to form a social structure which is characteristic of that species in the wild. In response to the rapid decline of wild African lion (Panthera leo populations, an array of conservational strategies have been adopted. Ex situ reintroduction of the African lion requires the construction of socially cohesive pride structures prior to wild release. This pilot study adopted a social network theory approach to quantitatively assess a captive pride's social structure and the relationships between individuals within them. Group composition (who is present in a group and social interaction data (social licking, greeting, play was observed and recorded to assess social cohesion within a released semi-wild pride. UCINET and SOCPROG software was utilised to represent and analyse these social networks. Results indicate that the pride is socially cohesive, does not exhibit random associations, and the role of socially influential keystone individuals is important for maintaining social bondedness within a lion pride. These results are potentially informative for the structure of lion prides, in captivity and in the wild, and could have implications for captive and wild-founder reintroductions.

In the field of health, information and communication technology (ICT) can create a space that, regardless of place or time, enables information to be shared and disseminated quickly. In addition to the usual challenges of evaluating public health activities, other difficulties are present when evaluating activities using ICT, such as lack of previous standards, unknown individual exposure or lack of information on the characteristics of those exposed. The aim of this paper is to describe some tools and indicators that may help to assess the scope, use and parameters related to website positioning on search engines as well as the connected social networks.

Full Text Available Purpose - The purpose of this paper is to analyze the mediating effect of the identification of valuable external knowledge on the relationship between the development of inter-organizational ties (structural social capital and the acquisition of external knowledge. Design/methodology/approach - Using a sample of 87 firms from Spanish biotechnology and pharmaceutics industries, the authors have tested the proposed mediation hypothesis by applying the partial least squares technique to a structural equations model. Findings - The study results show that those firms with stronger, more frequent and closer inter-relationships are able to increase the amount of intentionally acquired knowledge, partly due to the greater level of development of their knowledge identification capability. Thus, firms with a higher capability to recognize the value of the knowledge embedded in their inter-organizational networks will be more likely to design better strategies to acquire and integrate such knowledge into their current knowledge bases for either present or future use. Originality/value - This research contributes to knowledge management and social capital literature by means of the study of two key determinants of knowledge acquisition – structural social capital and knowledge identification capability – and the explanation of their relationships of mutual influence. The paper thus tries to fill this literature gap and connects the relational perspective of social capital with the knowledge-based view from a strategic point of view.

Full Text Available The research which was realized belongs to one of three research fields within framework of rational-emotional-behavioral therapy (REBT - to the theory of emotional disorders. It was undertaken with the aim to establish presence and nature of relations between social anxiety, treated as dimension and the construct of irrational beliefs from REBT theory. The research was carried out on the sample of 261 students of Novi Sad University, both genders, age 18 to 26. First of all, the latent structure of newly constructed Scale of Social Anxiety (SA of the author Tovilović S. was tested. SA scale was proved to be of satisfying reliability (α =0.92. Principal-component factor analysis was conducted under gathered data. Four factors of social anxiety, which explain 44,09% of total variance of the items of SA scale, were named: social-evaluation anxiety, inhibition in social-uncertain situations, low self-respect and hypersensitivity on rejection. The other test that was used is Scale of General Attitudes and Beliefs of the author Marić Z. Reliability of the sub-scale of irrational beliefs that was got on our sample is α =0.91 yet the subscale of rational beliefs is α =0.70. Canonical correlational analysis was conducted under manifest variables of both scales. Three pairs of statistically significant canonical factors were got, with correlations within the span between Rc=0.78 and Rc=0.64. We discussed nature of correlation between social anxiety and irrational beliefs in the light of REBT model of social phobia, REBT theory of emotional disorder, researches and model of social anxiety in wider, cognitive-behavioral framework.

Social ecological models suggest that conditions in the social and physical environment, in addition to individual factors, play important roles in health behavior change. Using structural equation modeling, this study tested a theoretically and empirically based explanatory model of physical activity to examine theorized direct and indirect effects of individual (e.g., motivation and self-efficacy), social environmental (e.g., social support), and physical environmental factors (e.g., neighborhood quality and availability of facilities). A community-based sample of adults (N = 910) was recruited from 2 public health centers (67% female, 43% African American, 43% motivation for physical activity, perceived social support, self-efficacy, and perceptions of the physical environment. Results indicated that (a) perceptions of the physical environment had direct effects on physical activity, (b) both the social and physical environments had indirect effects on physical activity through motivation and self-efficacy, and (c) social support influenced physical activity indirectly through intrinsic and extrinsic motivation. For all forms of activity, self-efficacy was the strongest direct correlate of physical activity, and evidence of a positive dose-response relation emerged between self-efficacy and intensity of physical activity. Findings from this research highlight the interactive role of individual and environmental influences on physical activity.

Active influence in dynamical models of structural balance in social networks

Summers, Tyler H.; Shames, Iman

2013-07-01

We consider a nonlinear dynamical system on a signed graph, which can be interpreted as a mathematical model of social networks in which the links can have both positive and negative connotations. In accordance with a concept from social psychology called structural balance, the negative links play a key role in both the structure and dynamics of the network. Recent research has shown that in a nonlinear dynamical system modeling the time evolution of “friendliness levels” in the network, two opposing factions emerge from almost any initial condition. Here we study active external influence in this dynamical model and show that any agent in the network can achieve any desired structurally balanced state from any initial condition by perturbing its own local friendliness levels. Based on this result, we also introduce a new network centrality measure for signed networks. The results are illustrated in an international-relations network using United Nations voting record data from 1946 to 2008 to estimate friendliness levels amongst various countries.

In mobile social groups, influence patterns driving group movement can vary between democratic and despotic. The arrival at any single pattern of influence is thought to be underpinned by both environmental factors and group composition. To identify the specific patterns of influence driving travel decision-making in a chacma baboon troop, we used spatially explicit data to extract patterns of individual movement bias. We scaled these estimates of individual-level bias to the level of the group by constructing an influence network and assessing its emergent structural properties. Our results indicate that there is heterogeneity in movement bias: individual animals respond consistently to particular group members, and higher-ranking animals are more likely to influence the movement of others. This heterogeneity resulted in a group-level network structure that consisted of a single core and two outer shells. Here, the presence of a core suggests that a set of highly interdependent animals drove routine group movements. These results suggest that heterogeneity at the individual level can lead to group-level influence structures, and that movement patterns in mobile social groups can add to the exploration of both how these structures develop (i.e. mechanistic aspects) and what consequences they have for individual- and group-level outcomes (i.e. functional aspects).

The influence of social structure on brood survival and development in a socially polymorphic ant: insights from a cross-fostering experiment.

Science.gov (United States)

Purcell, Jessica; Chapuisat, M

2012-11-01

Animal societies vary in the number of breeders per group, which affects many socially and ecologically relevant traits. In several social insect species, including our study species Formica selysi, the presence of either one or multiple reproducing females per colony is generally associated with differences in a suite of traits such as the body size of individuals. However, the proximate mechanisms and ontogenetic processes generating such differences between social structures are poorly known. Here, we cross-fostered eggs originating from single-queen (= monogynous) or multiple-queen (= polygynous) colonies into experimental groups of workers from each social structure to investigate whether differences in offspring survival, development time and body size are shaped by the genotype and/or prefoster maternal effects present in the eggs, or by the social origin of the rearing workers. Eggs produced by polygynous queens were more likely to survive to adulthood than eggs from monogynous queens, regardless of the social origin of the rearing workers. However, brood from monogynous queens grew faster than brood from polygynous queens. The social origin of the rearing workers influenced the probability of brood survival, with workers from monogynous colonies rearing more brood to adulthood than workers from polygynous colonies. The social origin of eggs or rearing workers had no significant effect on the head size of the resulting workers in our standardized laboratory conditions. Overall, the social backgrounds of the parents and of the rearing workers appear to shape distinct survival and developmental traits of ant brood. © 2012 The Authors.

Quantifying social asymmetric structures.

Science.gov (United States)

Solanas, Antonio; Salafranca, Lluís; Riba, Carles; Sierra, Vicenta; Leiva, David

2006-08-01

Many social phenomena involve a set of dyadic relations among agents whose actions may be dependent. Although individualistic approaches have frequently been applied to analyze social processes, these are not generally concerned with dyadic relations, nor do they deal with dependency. This article describes a mathematical procedure for analyzing dyadic interactions in a social system. The proposed method consists mainly of decomposing asymmetric data into their symmetric and skew-symmetric parts. A quantification of skew symmetry for a social system can be obtained by dividing the norm of the skew-symmetric matrix by the norm of the asymmetric matrix. This calculation makes available to researchers a quantity related to the amount of dyadic reciprocity. With regard to agents, the procedure enables researchers to identify those whose behavior is asymmetric with respect to all agents. It is also possible to derive symmetric measurements among agents and to use multivariate statistical techniques.

Social anxiety and eating disorder comorbidity: The role of negative social evaluation fears

Science.gov (United States)

Levinson, Cheri A.; Rodebaugh, Thomas L.

2011-01-01

Social anxiety and eating disorders are highly comorbid. However, it is unknown how specific domains of social anxiety relate to disordered eating. We provide data on these relationships and investigate social appearance anxiety and fear of negative evaluation as potential vulnerabilities linking social anxiety with eating disorders. Specifically, we examined five domains of social anxiety: Social interaction anxiety, fear of scrutiny, fear of positive evaluation, fear of negative evaluation, and social appearance anxiety. Results indicated that social appearance anxiety predicted body dissatisfaction, bulimia symptoms, shape concern, weight concern, and eating concern over and above fear of scrutiny, social interaction anxiety, and fear of positive evaluation. Fear of negative evaluation uniquely predicted drive for thinness and restraint. Structural equation modeling supported a model in which social appearance anxiety and fear of negative evaluation are vulnerabilities for both social anxiety and eating disorder symptoms. Interventions that target these negative social evaluation fears may help prevent development of eating disorders. PMID:22177392

Does landscape connectivity shape local and global social network structure in white-tailed deer?

Directory of Open Access Journals (Sweden)

Erin L Koen

Full Text Available Intraspecific social behavior can be influenced by both intrinsic and extrinsic factors. While much research has focused on how characteristics of individuals influence their roles in social networks, we were interested in the role that landscape structure plays in animal sociality at both individual (local and population (global levels. We used female white-tailed deer (Odocoileus virginianus in Illinois, USA, to investigate the potential effect of landscape on social network structure by weighting the edges of seasonal social networks with association rate (based on proximity inferred from GPS collar data. At the local level, we found that sociality among female deer in neighboring social groups (n = 36 was mainly explained by their home range overlap, with two exceptions: 1 during fawning in an area of mixed forest and grassland, deer whose home ranges had low forest connectivity were more social than expected; and 2 during the rut in an area of intensive agriculture, deer inhabiting home ranges with high amount and connectedness of agriculture were more social than expected. At the global scale, we found that deer populations (n = 7 in areas with highly connected forest-agriculture edge, a high proportion of agriculture, and a low proportion of forest tended to have higher weighted network closeness, although low sample size precluded statistical significance. This result implies that infectious disease could spread faster in deer populations inhabiting such landscapes. Our work advances the general understanding of animal social networks, demonstrating how landscape features can underlie differences in social behavior both within and among wildlife social networks.

Modern Social Support Structures: Online Social Networks and their Implications for Social Workers

Full Text Available Mapping and assessing social networks and the quality of their social support is a valuable intervention strategy for social workers. These networks have now spread onto the digital realm in the form of Online Social Networks (OSNs. This study investigated the nature of social support provided by such networks to their users in a rural mid-South University (USA and explored parallels with the current understanding of social support in conventional social networks. A web-based survey administered to college students revealed that users of these online networks were predominantly undergraduate first year students, female, single, unemployed and from a variety of academic disciplines. The examination of the components of OSNs appears to mirror those of offline networks. They also seem to complement the effects of each other while contributing to an individual's support system. The paper concludes with critical implications of such online social networking for University students and social workers in practice and education.

The aim of this study was to explore whether structural quality indicators for nutritional care influence malnutrition prevalence in the Netherlands, Germany, and Austria. Furthermore, differences in malnutrition prevalence and structural quality indicators for nutritional care nursing homes in the three countries were examined. This was a cross-sectional, multicenter study using a standardized questionnaire at the patient, ward, and institutional levels. Malnutrition was assessed by low body mass index, undesired weight loss, and reduced intake. Structural quality indicators of nutritional care were measured at the ward and institutional levels. The prevalence of malnutrition differed significantly between the three countries (Netherlands 18%, Germany 20%, and Austria 22.7%). Structural quality indicators related to nutritional care as having a guideline of prevention and treatment of malnutrition were related to malnutrition and explained malnutrition prevalence variance between the Netherlands and Germany. Differences between the Netherlands and Austria in malnutrition prevalence still existed after controlling for these quality structural indicators. Structural quality indicators of nutritional care are important in explaining malnutrition variance between the Netherlands and Germany. However, they did not explain the difference in malnutrition prevalence between the Netherlands and Austria. Investigating the role of process indicators may provide insight in the role of structural quality indicators of nutritional care in explaining the malnutrition prevalence differences between the Netherlands and Austria.

The emergency department (ED) can be a critical intervention point for many patients with multifaceted needs. Social workers have long been part of interdisciplinary ED teams. This study aimed to contribute to the limited understanding of social worker-patient interactions and factors influencing social work services in this setting. This paper reports a qualitative content analysis of social work medical record notes (N = 1509) of services provided to trauma patients in an urban, public, level 1 trauma center and an in-depth analysis of semi-structured interviews with ED social workers (N = 10). Eight major social work roles were identified: investigator, gatekeeper, resource broker, care coordinator, problem solver, crisis manager, advocate, discharge planner. Analyses revealed a complex interplay between ED social work services and multi-layered contexts. Using a social-ecological framework, we identified the interactions between micro or individual level factors, mezzo or local system level factors and macro environmental and systemic factors that play a role in ED interactions and patient services. Macro-level contextual influences were socio-structural forces including socioeconomic barriers to health, social hierarchies that reflected power differentials between providers and patients, and distrust or bias. Mezzo-level forces were limited resources, lack of healthcare system coordination, a challenging hierarchy within the medical model and the pressure to discharge patients quickly. Micro-level factors included characteristics of patients and social workers, complexity of patient stressors, empathic strain, lack of closure and compassion. All of these forces were at play in patient-social worker interactions and impacted service provision. Social workers were at times able to successfully navigate these forces, yet at other times these challenges were insurmountable.

The study of subjective perceptions of labor is an important indicator of public administration efficiency. The article contains the analysis of the population’s satisfaction with labor, particularly, with one of its structural components – labor conditions. It reveals the high correlation of these indicators with the satisfaction with everyday life and labor productivity. It determines the degree of employees’ satisfaction with working conditions in such areas as health and psychological atmosphere at the workplace, equipment capability and security. The study discloses employees’ estimates in socio-demographic and territorialdimensional aspects. The research demonstrates the interrelation between satisfaction with working environment and implementation of labor potential. The analysis indicates the importance of regular sociological research into the issues of satisfaction with various aspects of labor activity. The article indicates that for the country’s development it is necessary to take into account the labor satisfaction factor (in the narrow sense – working conditions while developing strategies and approaches for social-economic policy and defining the standards of social responsibility, primarily, of the state and employers

Full Text Available The present work aimed at investigating relations between maternal child-rearing practices, externalizing behavior problems and social competence indicators of thirty-month-old children. The study involved 23 child-mother dyads. In the child's thirtieth month after birth, an observation of mother-child interaction was performed in order to evaluate maternal child-rearing practices, externalizing behavior problems and child social competence. The results support the literature about social development that relates child-rearing practices such as guidance, assertive control and positive parental involvement to social competence, and coercive and permissive practices to externalizing behavior problems. The work discusses the relevance of parental child-rearing practices for the comprehension of the social development, emphasizing the importance of child-rearing practices, such as autonomy authorization, intrusiveness and ambiguous control.

Full Text Available The indicators, precisely describing the linkages between tourism and the environment, social and cultural base, are not easily available. How ever, some relevant organizations (WTO, EU, OECD, etc., institutions and experts, have been hardly working to create the indicators of sustainable tourism. Whereas the economic objectives are easily defined by the use of the traditional indicators used in national and business economics, it is very difficult to identify widely applicable environmental, social and cultural indicators. In order to stimulate and alleviate the process of sustainable tourism development, EU created the list of comparative indicators of sustainable tourism. In preparing this list, special attention is paid to identification of valid indicators of real tourism impacts on the social and cultural environment (the entire set of traditions, customs, history, hospitality and culture that characterize a given area, that is a very complex task. Assuming the fact that the related indicators have been analyzed in many European countries, this paper is focused on applying the related indicators in research of tourism development in villages of the Kosjerić community. .

2006-03-01

Full Text Available Abstract Background Prediction of protein folding and specific interactions from only the sequence (ab initio is a major challenge in bioinformatics. It is believed that such prediction will prove possible if Anfinsen's thermodynamic principle is correct for all kinds of proteins, and all the information necessary to form a concrete 3D structure is indeed present in the sequence. Results We indexed the 200 possible amino acid pairs for their compatibility regarding the three major physicochemical properties – size, charge and hydrophobicity – and constructed Size, Charge and Hydropathy Compatibility Indices and Matrices (SCI & SCM, CCI & CCM, and HCI & HCM. Each index characterized the expected strength of interaction (compatibility of two amino acids by numbers from 1 (not compatible to 20 (highly compatible. We found statistically significant positive correlations between these indices and the propensity for amino acid co-locations in real protein structures (a sample containing total 34630 co-locations in 80 different protein structures: for HCI: p We tried to predict or reconstruct simple 2D representations of 3D structures from the sequence using these matrices by applying a dot plot-like method. The location and pattern of the most compatible subsequences was very similar or identical when the three fundamentally different matrices were used, which indicates the consistency of physicochemical compatibility. However, it was not sufficient to choose one preferred configuration between the many possible predicted options. Conclusion Indexing of amino acids for major physico-chemical properties is a powerful approach to understanding and assisting protein design. However, it is probably insufficient itself for complete ab initio structure prediction.

Full Text Available Background. Nowadays, a comprehensive assessment of osteoporosis and the risk of osteoporotic fractures involves the combine use of bone mineral density (BMD, 10-year probability of major osteoporotic fractures (Fracture Risk Assessment Tool, Trabecular Bone Score, and parameters of hip structural ana­lysis. In recent years, reference data on the three above-mentioned methods have been developed for the Ukrainian population, but there are no data on the latest methodology. The objective of the study was to assess the age characteristics of hip structural analysis parameters in Ukrainian women and to offer their reference values for use in clinical practice. Materials and methods. Using the dual energy X-ray absorptiometry method, we examined 690 healthy women aged 20–89 years wi­thout osteoporosis and other clinically significant diseases and conditions affecting the bone metabolism, without other accompanying pathology of hip joint.

The presented framework constitutes a null model for social spreading phenomena that, in contrast to purely empirical studies or simulation-based models, clearly distinguishes the roles of two distinct factors affecting meme popularity: the memory time of users and the connectivity structure of the social network.

Some efforts to assess sustainability on the urban scale have been made and different tools for measuring the impact on and caused by cities have emerged. However, the sustainability concept varies from region to region, and indicators to measure it should be suitable for the context-specific conditions of the region under study. After doing a comprehensive review of the indicators included in 13 tools developed to assess urban sustainability of cities, this article proposes a new structure of indicators adapted to a Mediterranean city in Spain. The proposed structure is based on a two-level scheme that consists in 14 categories and 63 subcategories, which agglutinate urban sustainability indicators according to their purpose. This structure suggests a set of comprehensible qualitative and quantitative indicators that are easily applicable on neighbourhood or city scales. Given the similar features of Mediterranean countries in terms of environmental and socio-economic aspects, the proposed structure could be extrapolated to other countries with climatic and cultural similarities. Otherwise, the system is a useful tool in the decision-making process to help the different stakeholders involved in new urban developments and regeneration projects in existing neighbourhoods, such as developers, urban planners and public administrations. - Highlights: • Comprehensive review of 13 urban sustainability assessment tools • Proposal of a two-level structure to cluster urban sustainability indicators • Inclusion of sustainability criteria for urban planning projects and interventions.

Full Text Available Years of social, economic, and political changes have resulted in intensive and extensive migration activity. The appearance of compelled and voluntary migrants has brought about the development of a new direction in social psychology: the psychology of migration. Many disciplines are connected with the study of migration, the problems of migrants, and adaptation processes. In the social-psychological literature, various models of adaptation to new conditions of a social-cultural environment are considered (I. Jasinskaja-Lahti, K. Liebkind, J. Berry; S.-K. Lee, J. Sobal, E. Frongillo. Various social-psychological features of migrants are studied: for example, ethnic identity, characteristics of psychological adaptation, emotional well-being, and mental health. In the Russian scientific literature the following problems are considered: emigrants’ interactions with representatives of foreign cultures (N. S. Khrustaleva, degree of cultural similarity (T.G. Stefanenko, personal features of emigrants (S. H. Schwartz, E. Prince-Gibson, features of ethnic identity (G.U. Soldatova, S. D. Gurieva, and many others. In Russia, research regarding the influence of the social-cultural environment on processes of adaptation were begun only in 2004. The main objective of our study was to identify psychological mechanisms of migration flows (incoming and outgoing as indicators of sociopolitical and psychological stability in the Pskov Region. Participants in the study were citizens permanently residing in the Pskov Region who by age and social characteristics represented the population structure of a part of that region. In total, 52 persons aged 17 to 69, with an average age of 42.3, participated. The technique used was focus groups. A content analysis was made of the answers received in the focus-group sessions. During these sessions, participants could freely share their views on questions asked by the facilitators who had a college-level psychological

Peer cliques form an important context for the social development of adolescents. Although clique members are often similar in social status, also within cliques, status differences exist. How differences in social status between clique members are related to behaviors of its individual members is rather unknown. This study examined to what extent the relationship of individual social status (i.e., perceived popularity) with aggression and prosocial behavior depends on the level of internal clique hierarchy. The sample consists of 2674 adolescents (49.8% boys), with a mean age of 14.02. We focused specifically on physical and relational aggression, and practical and emotional support, because these behaviors have shown to be of great importance for social relationships and social standing among adolescents. The internal status hierarchy of cliques was based on the variation in individual social status between clique members (i.e., clique hierarchization) and the structure of status scores within a clique (pyramid shape, inverted pyramid, or equal distribution of social status scores) (i.e., clique status structure). The results showed that differences in aggressive and prosocial behaviors were particularly moderated by clique status structure: aggression was stronger related to individual social status in (girls') cliques where the clique status structure reflected an inverted pyramid with relatively more high status adolescents within the clique than low status peers, and prosocial behavior showed a significant relationship with individual social status, again predominantly in inverted pyramid structured (boys' and girls') cliques. Furthermore, these effects differed by types of gender cliques: the associations were found in same gender but not mixed-gender cliques. The findings stress the importance of taking into account internal clique characteristics when studying adolescent social status in relationship to aggression and prosociality.

Full Text Available The purpose of this study was to investigate the effects of structured physical activity program on social interaction and communication of children with autism spectrum disorder (ASD. Fifty children with ASD from a special school were randomly divided into experimental and control groups. 25 children with ASD were placed in the experimental group, and the other 25 children as the control group participated in regular physical activity. A total of forty-one participants completed the study. A 12-week structured physical activity program was implemented with a total of 24 exercise sessions targeting social interaction and communication of children with ASD, and a quasi-experimental design was used for this study. Data were collected using quantitative and qualitative instruments. SSIS and ABLLS-R results showed that an overall improvement in social skills and social interaction for the experimental group across interim and posttests, F=8.425, p=0.001 (p0.005. The study concluded that the special structured physical activity program positively influenced social interaction and communication skills of children with ASD, especially in social skills, communication, prompt response, and frequency of expression.

Income situation of households as a social status indicator

Jana Stávková

2013-01-01

Full Text Available The net financial income of households plays a crucial role in assessing their living standard. It determines of which social class they are members and, thus, their social status as well. In order to monitor their income situation, this paper uses survey data of the European Union Statistics on Income and Living Conditions (EU SILC. An abundance of identification data, such as economic activity, industrial classification or sector of economic activity, level of education, age, number of household members, place of residence, household type and others, makes it possible to identify factors that demonstrably influence the household income level. On this basis, it is possible not only to determine the commonly available social class definitions using income intervals, but also to identify specific causes affecting household income and, thus, link a particular household to a given social class. The goal of this article is to establish which factors influence the income level of households. The authors of this paper focused on four factors: social group membership, occupation classified according to the national economy sectors, the highest level of education attained by the household leader and their age. To analyse the influence of selected factors including their interaction and impact on the income situation of households, the authors applied the method of analysing variance between groups (ANOVA using STATA statistical software. The Scheffe’s method of contrasts was used to determine specific differences between factor levels.

Isotopic diversity indices: how sensitive to food web structure?

Science.gov (United States)

Brind'Amour, Anik; Dubois, Stanislas F

2013-01-01

Recently revisited, the concept of niche ecology has lead to the formalisation of functional and trophic niches using stable isotope ratios. Isotopic diversity indices (IDI) derived from a set of measures assessing the dispersion/distribution of points in the δ-space were recently suggested and increasingly used in the literature. However, three main critics emerge from the use of these IDI: 1) they fail to account for the isotopic sources overlap, 2) some indices are highly sensitive to the number of species and/or the presence of rare species, and 3) the lack of standardization prevents any spatial and temporal comparisons. Using simulations we investigated the ability of six commonly used IDI to discriminate among different trophic food web structures, with a focus on the first two critics. We tested the sensitivity of the IDI to five food web structures along a gradient of sources overlap, varying from two distinct food chains with differentiated sources to two superimposed food chains sharing two sources. For each of the food web structure we varied the number of species (from 10 to 100 species) and the type of species feeding behaviour (i.e. random or selective feeding). Values of IDI were generally larger in food webs with distinct basal sources and tended to decrease as the superimposition of the food chains increased. This was more pronounced when species displayed food preferences in comparison to food webs where species fed randomly on any prey. The number of species composing the food web also had strong effects on the metrics, including those that were supposedly less sensitive to small sample size. In all cases, computing IDI on food webs with low numbers of species always increases the uncertainty of the metrics. A threshold of ~20 species was detected above which several metrics can be safely used.

Seeking structure in social organization: compensatory control and the psychological advantages of hierarchy.

Science.gov (United States)

Friesen, Justin P; Kay, Aaron C; Eibach, Richard P; Galinsky, Adam D

2014-04-01

Hierarchies are a ubiquitous form of human social organization. We hypothesized that 1 reason for the prevalence of hierarchies is that they offer structure and therefore satisfy the core motivational needs for order and control relative to less structured forms of social organization. This hypothesis is rooted in compensatory control theory, which posits that (a) individuals have a basic need to perceive the world as orderly and structured, and (b) personal and external sources of control are capable of satisfying this need because both serve the comforting belief that the world operates in an orderly fashion. Our first 2 studies confirmed that hierarchies were perceived as more structured and orderly relative to egalitarian arrangements (Study 1) and that working in a hierarchical workplace promotes a feeling of self-efficacy (Study 2). We threatened participants' sense of personal control and measured perceptions of and preferences for hierarchy in 5 subsequent experiments. Participants who lacked control perceived more hierarchy occurring in ambiguous social situations (Study 3) and preferred hierarchy more strongly in workplace contexts (Studies 4-5). We also provide evidence that hierarchies are indeed appealing because of their structure: Preference for hierarchy was higher among individuals high in Personal Need for Structure and a control threat increased preference for hierarchy even among participants low in Personal Need for Structure (Study 5). Framing a hierarchy as unstructured reversed the effect of control threat on hierarchy (Study 6). Finally, hierarchy-enhancing jobs were more appealing after control threat, even when they were low in power and status (Study 7). (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Full Text Available Abstract Background & aim: Nearly a decade the World Health Organization has tried to provide a unique definition of community mental health. But due to the complexity of psychosocial and cultural context, it is not provided. The purpose of the study was to determine indexes community mental health of children and adolescents in the province of Kohgiluyeh and Boyerahmad. Methods: This study was conducted as a hybrid approach (qualitative and quantitative. Delphi technique was used in qualitative research. In the current study, 31 experts, children and adolescents of Social Welfare organizations were selected as snowball method throughout the province of Kohgiluyeh & Boyerahmad. The primary data to run the Delphi Technique was gathered in three stages from the participants. The quantitative data were analyzed using factor analysis. Results: The results indicated that the main indicators of psychosocial health lie in intrapersonal (emotional self-awareness, risk-taking and self-respect, interpersonal (participation, social responsibility, and social relationships, stress (stress management and controlling emotions and adaptability (flexibility and happiness components. The results also showed that decreasing gender-related discriminations and rise in the educational level of parents are the major strengths and lack of required standards in child-care centers, lack of involvement of young adolescents in decision-making and lack of social skills in families are the major weaknesses of psychosocial health. Conclusion: Given the right conditions, and in order to safeguard children and adolescents against the grave consequences awaiting them, the organizations charged with the responsibility should raise the children and adolescents in such a way that they meet the professional needs of the society and feel responsible when it comes to these responsibilities and commitments.

Shyness and social anxiety are correlated to some extent and both are associated with hyper-responsivity to social stimuli in the frontal cortex and limbic system. However to date no studies have investigated whether common structural and functional connectivity differences in the brain may contribute to these traits. We addressed this issue in a cohort of 61 healthy adult subjects. Subjects were first assessed for their levels of shyness (Cheek and Buss Shyness scale) and social anxiety (Liebowitz Social Anxiety scale) and trait anxiety. They were then given MRI scans and voxel-based morphometry and seed-based, resting-state functional connectivity analysis investigated correlations with shyness and anxiety scores. Shyness scores were positively correlated with gray matter density in the cerebellum, bilateral superior temporal gyri and parahippocampal gyri and right insula. Functional connectivity correlations with shyness were found between the superior temporal gyrus, parahippocampal gyrus and the frontal gyri, between the insula and precentral gyrus and inferior parietal lobule, and between the cerebellum and precuneus. Additional correlations were found for amygdala connectivity with the medial frontal gyrus, superior frontal gyrus and inferior parietal lobule, despite the absence of any structural correlation. By contrast no structural or functional connectivity measures correlated with social or trait anxiety. Our findings show that shyness is specifically associated with structural and functional connectivity changes in cortical and limbic regions involved with processing social stimuli. These associations are not found with social or trait anxiety in healthy subjects despite some behavioral correlations with shyness. PMID:23675458

An understanding of the contributing factors to be considered when examining how individuals engage in physical activity is important for promoting population-based physical activity. The environment influences long-term effects on population-based health behaviors. Personal variables, such as self-efficacy and social support, can act as mediators of the predictive relationship between the environment and physical activity. The present study examines the direct and indirect effects of environmental, psychological, and social factors on walking, moderate-intensity activity excluding walking, and vigorous-intensity activity among Japanese adults. The participants included 1,928 Japanese adults aged 20-79 years. Seven sociodemographic attributes (e.g., gender, age, education level, employment status), psychological variables (self-efficacy, pros, and cons), social variables (social support), environmental variables (home fitness equipment, access to facilities, neighborhood safety, aesthetic sensibilities, and frequency of observing others exercising), and the International Physical Activity Questionnaire were assessed via an Internet-based survey. Structural equation modeling was conducted to determine associations between environmental, psychological, and social factors with physical activity. Environmental factors could be seen to have indirect effects on physical activity through their influence on psychological and social variables such as self-efficacy, pros and cons, and social support. The strongest indirect effects could be observed by examining the consequences of environmental factors on physical activity through cons to self-efficacy. The total effects of environmental factors on physical activity were 0.02 on walking, 0.02 on moderate-intensity activity excluding walking, and 0.05 on vigorous-intensity activity.

Ward and Zahavi suggested in 1973 that colonies could serve as information centres, through a transfer of information on the location of food resources between unrelated individuals (Information Centre Hypothesis). Using GPS tracking and observations on group movements, we studied the search strategy and information transfer in two of the most colonial seabirds, Guanay cormorants (Phalacrocorax bougainvillii) and Peruvian boobies (Sula variegata). Both species breed together and feed on the same prey. They do return to the same feeding zone from one trip to the next indicating high unpredictability in the location of food resources. We found that the Guanay cormorants use social information to select their bearing when departing the colony. They form a raft at the sea surface whose position is continuously adjusted to the bearing of the largest returning columns of cormorants. As such, the raft serves as a compass signal that gives an indication on the location of the food patches. Conversely, Peruvian boobies rely mainly on personal information based on memory to take heading at departure. They search for food patches solitarily or in small groups through network foraging by detecting the white plumage of congeners visible at long distance. Our results show that information transfer does occur and we propose a new mechanism of information transfer based on the use of rafts off colonies. The use of rafts for information transfer may be common in central place foraging colonial seabirds that exploit short lasting and/or unpredictably distributed food patches. Over the past decades Guanay cormorants have declined ten times whereas Peruvian boobies have remained relatively stable. We suggest that the decline of the cormorants could be related to reduced social information opportunities and that social behaviour and search strategies have the potential to play an important role in the population dynamics of colonial animals.

Full Text Available This research aims to explore correlations between consumer-generated social media activity and the level of sales of German brands from the fast moving consumer goods industry. In particular, the objective was to examine whether there is a correlation between the number of brand mentions in social media and the sales of these products. The results indicate that the number of brand mentions and sales correlate positively in relation to products from the food and beverages category while this is not the case with respect to the non-food product category. Hence, marketers need to promote consumer-generated social media activity particularly for food and beverages.

Application of Social Vulnerability Indicators to Climate Change for the Southwest Coastal Areas of Taiwan

2016-12-01

Full Text Available The impact of climate change on the coastal zones of Taiwan not only affects the marine environment, ecology, and human communities whose economies rely heavily on marine activities, but also the sustainable development of national economics. The southwest coast is known as the area most vulnerable to climate change; therefore, this study aims to develop indicators to assess social vulnerability in this area of Taiwan using the three dimensions of susceptibility, resistance, and resilience. The modified Delphi method was used to develop nine criteria and 26 indexes in the evaluation, and the analytic hierarchy process method was employed to evaluate the weight of each indicator based on the perspectives of experts collected through questionnaire surveys. The results provide important information pertaining to the vulnerability of the most susceptive regions, the lowest-resistance areas, and the least resilient townships on the southwest coast. The most socially vulnerable areas are plotted based on the present analysis. Experts can consider the vulnerability map provided here when developing adaptation policies. It should be kept in mind that improving the capacities of resistance and resilience is more important than reducing susceptibility in Taiwan.

Address rituals as heuristics of social structure

2013-02-01

Full Text Available The address form as linguistic variable has more realisation possibilities than any other, because semantic variation is involved and it reflects all the different interpersonal relations in the societal structure. Factors such as religious status, sex, kinship and age differences play a key role in the choice of the address form. It is hypothesised that the way in which address forms vary in a speech community is a linguistic reflection of the social norms determining the hierarchical structure of the community. Die aanspreekvorm as linguistiese veranderlike het meer verwesenlikingsmoontlikhede as enige ander vorm, want semantiese verskeidenheid is betrokke en dit reflekteer die verskillende interpersoonlike verhoudings in die gemeenskapstruktuur. Faktore soos religieuse status, geslag, verwantskap en ouderdomsverskille speel 'n sleutelrol in die aanspreekvorm. Daar word gehipotetiseer dat die wyse waarop aanspreekvorms in 'n spraakgemeenskap wissel, 'n linguistiese refleksie is van die sosiale norme wat die hierargiese struktuur van die gemeenskap bepaal.

Stringfellow, Erin J

2017-03-01

Innovation will be key to the success of the Grand Challenges Initiative in social work. A structural systems framework based in system dynamics could be useful for considering how to advance innovation. Diagrams using system dynamics conventions were developed to link common themes across concept papers written by social work faculty members and graduate students ( N = 19). Transdisciplinary teams and ethical partnerships with communities and practitioners will be needed to responsibly develop high-quality innovative solutions. A useful next step would be to clarify to what extent factors that could "make or break" these partnerships arise from within versus outside of the field of social work and how this has changed over time. Advancing innovation in social work will mean making decisions in a complex, ever-changing system. Principles and tools from methods that account for complexity, such as system dynamics, can help improve this decision-making process.

Utilizing the social media data to validate 'climate change' indices

Science.gov (United States)

Molodtsova, T.; Kirilenko, A.; Stepchenkova, S.

2013-12-01

Reporting the observed and modeled changes in climate to public requires the measures understandable by the general audience. E.g., the NASA GISS Common Sense Climate Index (Hansen et al., 1998) reports the change in climate based on six practically observable parameters such as the air temperature exceeding the norm by one standard deviation. The utility of the constructed indices for reporting climate change depends, however, on an assumption that the selected parameters are felt and connected with the changing climate by a non-expert, which needs to be validated. Dynamic discussion of climate change issues in social media may provide data for this validation. We connected the intensity of public discussion of climate change in social networks with regional weather variations for the territory of the USA. We collected the entire 2012 population of Twitter microblogging activity on climate change topic, accumulating over 1.8 million separate records (tweets) globally. We identified the geographic location of the tweets and associated the daily and weekly intensity of twitting with the following parameters of weather for these locations: temperature anomalies, 'hot' temperature anomalies, 'cold' temperature anomalies, heavy rain/snow events. To account for non-weather related events we included the articles on climate change from the 'prestige press', a collection of major newspapers. We found that the regional changes in parameters of weather significantly affect the number of tweets published on climate change. This effect, however, is short-lived and varies throughout the country. We found that in different locations different weather parameters had the most significant effect on climate change microblogging activity. Overall 'hot' temperature anomalies had significant influence on climate change twitting intensity.

2016-01-01

Measuring the performance of business processes has become a central issue in both academia and business, since organizations are challenged to achieve effective and efficient results. Applying performance measurement models to this purpose ensures alignment with a business strategy, which implies that the choice of performance indicators is organization-dependent. Nonetheless, such measurement models generally suffer from a lack of guidance regarding the performance indicators that exist and how they can be concretized in practice. To fill this gap, we conducted a structured literature review to find patterns or trends in the research on business process performance measurement. The study also documents an extended list of 140 process-related performance indicators in a systematic manner by further categorizing them into 11 performance perspectives in order to gain a holistic view.

In particular, the objective was to examine whether there is a correlation between the number of brand mentions in social media and the sales of these products. The results indicate that the number of brand mentions and sales correlate positively in relation to products from the food and beverages category while this ...

Social structure and indirect genetic effects: genetics of social behaviour.

Schneider, Jonathan; Atallah, Jade; Levine, Joel D

2017-05-01

The social environment modulates gene expression, physiology, behaviour and patterns of inheritance. For more than 50 years, this concept has been investigated using approaches that include partitioning the social component out of behavioural heritability estimates, studying maternal effects on offspring, and analysing dominance hierarchies. Recent advances have formalized this 'social environment effect' by providing a more nuanced approach to the study of social influences on behaviour while recognizing evolutionary implications. Yet, in most of these formulations, the dynamics of social interactions are not accounted for. Also, the reciprocity between individual behaviour and group-level interactions has been largely ignored. Consistent with evolutionary theory, the principles of social interaction are conserved across a broad range of taxa. While noting parallels in diverse organisms, this review uses Drosophila melanogaster as a case study to revisit what is known about social interaction paradigms. We highlight the benefits of integrating the history and pattern of interactions among individuals for dissecting molecular mechanisms that underlie social modulation of behaviour. © 2016 The Authors.

Full Text Available The article aims at identifying the social structure and the inequality in monetary income of the population in Russia. identification of the social groups with different levels of material well-being in a society with a high inequality in the distribution of living standard is a relevant topic. The integration of normative and statistical methods allows to consider the limitations of the existing model of the distribution of cash income and adjust the boundaries of social groups with different levels of material well-being. At the same time, we stay within the criteria for the social standards of the differentiation of living standards. The authors have corrected the specific weight of the Russian social groups with different levels of material well-being. To define these social groups, we have applied the system of normative consumer budgets for different level of material well-being. This paper discovers the intervals for the levels of income and consumption, which are not in contradiction with the normative approach and existing conditions of the Russian economic development. These intervals are advisable for the identification of the social groups with different levels of life. The proposed tools allow to integrate the measurements into the international system and define the place of Russia in terms of economic inequalities among other countries. The authors have assessed the weights of the different social groups, their share in the total volume of monetary income and their polarization in terms of living standards. The main conclusions of the article can be used as a theoretical, methodological and practical basis for identifying social structures in terms of living standards, determining their numbers and economic inequality. The research results can be introduced into the statistical monitoring of the living standards of the population.

The Influence of Ethnic Diversity on Social Network Structure in a Common-Pool Resource System: Implications for Collaborative Management

Full Text Available Social networks have recently been identified as key features in facilitating or constraining collaborative arrangements that can enhance resource governance and adaptability in complex social-ecological systems. Nonetheless, the effect of ethnicity on social network structure in an ethnically diverse common-pool resource system is virtually unknown. We characterize the entire social network of Hawaii's longline fishery, an ethnically diverse competitive pelagic fishery, and investigate network homophily, network structure, and cross-scale linkages. Results show that ethnicity significantly influences social network structure and is responsible for a homophily effect, which can create challenges for stakeholder collaboration across groups. Our analysis also suggests that ethnicity influences the formation of diverse network structures, and can affect the level of linkages to outside industry leaders, government or management officials, and members of the scientific community. This study provides the first empirical examination of the impact of ethnic diversity on resource user's social networks in the common-pool resource literature, having important implications for collaborative resource management.

Working With Refugees in the U.S.: Trauma-Informed and Structurally Competent Social Work Approaches

Directory of Open Access Journals (Sweden)

Jason Ostrander

2017-09-01

Full Text Available Social workers, government, and non-governmental organizations in the United States have been inadequately prepared to address the impact of trauma faced by refugees fleeing persecution. Compounding their initial trauma experiences, refugees often undergo further traumatic migration experiences and challenges after resettlement that can have long-lasting effects on their health and mental health. Micro and macro social work practitioners must understand the impact of these experiences in order to promote policies, social work training, and clinical practice that further the health and well-being of refugees and society. Social workers are in a unique position to provide multi-dimensional, structurally competent care and advocacy for diverse refugee populations. The experiences of Cambodian refugees will be used to examine these issues. We will explore the benefits of an ecological perspective in guiding interventions that support refugees, and will apply the framework of structural competence to highlight multidimensional implications for social work with refugee populations.

It has been suggested that child sexual abuse is related to poor attachment to parents, which is associated with an inability to form intimate relationships. Seto and Lalumière indicated that there were too few studies of adolescent males to determine whether poor attachment was associated with perpetration. This study was designed to follow up on a previous study and further explored the association between insecure attachment to parents, social isolation, and interpersonal adequacy to child sexual abuse perpetration in adolescents. We compared two samples of adolescent males who had committed sexual offenses, those who committed offenses against children (n = 140) and those who committed offenses against peer or adults (n = 92), with a sample of similarly aged males in treatment for mental health or substance use issues (n = 93). Data were collected using a semi-structured interview and computer-administered questionnaire. We found an indirect association between anxious attachment and sexual offenses against child victims, which was accounted for by measures of social involvement and social isolation. These involvement and isolation measures also did not have a direct association with sexual offenses against child victims, in that their contribution was accounted for by a measure of Masculine Adequacy. This Masculine Adequacy, combined with decreased levels of Sexual Preoccupation and Hypersexuality and increased Sexual Compulsivity, was associated with commission of child sexual abuse. The interpersonal variables did not enter a model predicting sexual offending against peers/adults, which seemed solely associated with the interaction between Sexual Compulsivity and Hypersexuality. © The Author(s) 2014.

Evidence for an apartheid-like social structure in early Anglo-Saxon England.

Thomas, Mark G; Stumpf, Michael P H; Härke, Heinrich

2006-10-22

The role of migration in the Anglo-Saxon transition in England remains controversial. Archaeological and historical evidence is inconclusive, but current estimates of the contribution of migrants to the English population range from less than 10000 to as many as 200000. In contrast, recent studies based on Y-chromosome variation posit a considerably higher contribution to the modern English gene pool (50-100%). Historical evidence suggests that following the Anglo-Saxon transition, people of indigenous ethnicity were at an economic and legal disadvantage compared to those having Anglo-Saxon ethnicity. It is likely that such a disadvantage would lead to differential reproductive success. We examine the effect of differential reproductive success, coupled with limited intermarriage between distinct ethnic groups, on the spread of genetic variants. Computer simulations indicate that a social structure limiting intermarriage between indigenous Britons and an initially small Anglo-Saxon immigrant population provide a plausible explanation of the high degree of Continental male-line ancestry in England.

2005-12-01

This study continued the effort to apply social skills training to increase vocational outcomes of people with severe mental illness. We planned to identify factor structure of essential social skills necessary for mental health consumers who have a vocational preference to work as salesperson in retail market. Exploratory factor analysis of the results of a 26-item questionnaire survey suggested a five-factor solution: social skills when interacting with customers, problem-solving skills, knowledge and attitudes, flexibility, and skills for conflict prevention, which accounted for 65.1% of the total variance. With the factor solution, we developed a job-specific social skills training program (JSST) to help consumers who want to be salespersons. The structure and session design followed the basic format of a typical social skills training program. The way this JSST is to be used with the work-related social skills training model previously developed by the corresponding author to produce better vocational outcomes of consumers is suggested.

Military service is a crucial period in the lives of young people and during this period soldier facing with multiple psychosocial problems. The present study aimed to explore structural analysis of the relationships between depression, drug abuse, social support and the risk of suicidal ideation among Military Medical University soldiers in Iran. In the present correlational research, a sample of 176 soldiers, from three units, was selected using randomly stratified sampling. Data were collected through the Social Support Questionnaire (SSQ), the Beck Depression Inventory-II (BDI-II), the Beck Scale for Suicide Ideation (BSS) and the Possibility of Drug Abuse Scale (LDAS). Structural equation modeling was used to test the fit of the model, identify direct and indirect effects of the psychosocial correlates. Data were analyzed using the SPSS and AMOS software (Verson22). out of the whole subjects, 28.4% had suicidal ideation and 65.3% had degrees of depression (mild to severe). A significant reverse relationship was observed between social support and suicidal ideation (pdrug abuse and suicidal ideation. The final structural model indicated that 74% of the variance in suicidal ideation was explained by the three examined variables of depression, social support and drug abuse. The overall results showed that the risk of suicidal ideation, depression and drug abuse are relatively significant in Military Medical University soldiers requiring taking serious actions by the authorities and other relevant organizations in order to improve the psychosocial health status of these soldiers.

There have been various achievements to understand and to analyze the financial market by complex network model. However, current studies analyze the financial network model but seldom present quantified indexes to indicate or forecast the price action of market. In this paper, the stock market is modeled as a dynamic network, in which the vertices refer to listed companies and edges refer to their rank-based correlation based on price series. Characteristics of the network are analyzed and then novel indexes are introduced into market analysis, which are calculated from maximum and fully-connected subnets. The indexes are compared with existing ones and the results confirm that our indexes perform better to indicate the daily trend of market composite index in advance. Via investment simulation, the performance of our indexes is analyzed in detail. The results indicate that the dynamic complex network model could not only serve as a structural description of the financial market, but also work to predict the market and guide investment by indexes.

We investigate two paradigms for studying the evolution of cooperation-Prisoner's Dilemma and Snowdrift game in an online friendship network, obtained from a social networking site. By structural analysis, it is revealed that the empirical social network has small-world and scale-free properties. Besides, it exhibits assortative mixing pattern. Then, we study the evolutionary version of the two types of games on it. It is found that cooperation is substantially promoted with small values of game matrix parameters in both games. Whereas the competent cooperators induced by the underlying network of contacts will be dramatically inhibited with increasing values of the game parameters. Further, we explore the role of assortativity in evolution of cooperation by random edge rewiring. We find that increasing amount of assortativity will to a certain extent diminish the cooperation level. We also show that connected large hubs are capable of maintaining cooperation. The evolution of cooperation on empirical networks is influenced by various network effects in a combined manner, compared with that on model networks. Our results can help understand the cooperative behaviors in human groups and society

This report examines the interpretation of the Graph Derivative Indices (GDIs) from three different perspectives (i.e., in structural, steric and electronic terms). It is found that the individual vertex frequencies may be expressed in terms of the geometrical and electronic reactivity of the atoms and bonds, respectively. On the other hand, it is demonstrated that the GDIs are sensitive to progressive structural modifications in terms of: size, ramifications, electronic richness, conjugation effects and molecular symmetry. Moreover, it is observed that the GDIs quantify the interaction capacity among molecules and codify information on the activation entropy. A structure property relationship study reveals that there exists a direct correspondence between the individual frequencies of atoms and Hückel’s Free Valence, as well as between the atomic GDIs and the chemical shift in NMR, which collectively validates the theory that these indices codify steric and electronic information of the atoms in a molecule. Taking in consideration the regularity and coherence found in experiments performed with the GDIs, it is possible to say that GDIs possess plausible interpretation in structural and physicochemical terms.

The aim of this study was to investigate whether social structure is associated with cancer pain and quality of life using the Social Structure and Personality Research Framework. This study was a secondary analysis of data from 480 cancer patients. The measurements included socioeconomic variables, self-reported cancer pain using the McGill Pain Questionnaire-Short Form (MPQ-SF), and quality of life measured using the Functional Assessment of Cancer Therapy Scale (FACT-G). The data were analyzed using moderated multiple regression. Cancer pain and quality of life differed significantly with income. The associations between income and pain and quality of life were significant only for the high education group (≥ partial college), and these associations were greater for Caucasians than for their counterparts ( p life while considering possible moderating factors such as education.

Social Learning Theory, Gender, and Intimate Partner Violent Victimization: A Structural Equations Approach.

Powers, Ráchael A; Cochran, John K; Maskaly, Jon; Sellers, Christine S

2017-05-01

The purpose of this study is to examine the applicability of Akers's Social Learning Theory (SLT) to explain intimate partner violence (IPV) victimization. In doing so, we draw on the Intergenerational Transmission of Violence Theory (IGT) to extend the scope of SLT to the explanation of victimization and for a consideration of uniquely gendered pathways in its causal structure. Using a structural equation modeling approach with self-report data from a sample of college students, the present study tests the extent to which SLT can effectively explain and predict IPV victimization and the degree, if any, to which the social learning model is gender invariant. Although our findings are largely supportive of SLT and, thus, affirm its extension to victimization as well as perpetration, the findings are also somewhat mixed. More significantly, in line with IGT literature, we find that the social learning process is not gender invariant. The implications of the latter are discussed.

Social protection is high on the HIV-prevention agenda for youth in sub-Saharan Africa. However, questions remain: How do unconditional cash transfers work? What is the effect of augmenting cash provision with social care? And can "cash plus care" social protection reduce risks for adolescents most vulnerable to infection? This study tackles these questions by first identifying mediated pathways to adolescent HIV risks and then examining potential main and moderating effects of social protection in South Africa. This study was a prospective observational study of 3515 10-to-17-year-olds (56.7% female; 96.8% one-year retention). Within randomly selected census areas in four rural and urban districts in two South African provinces, all homes with a resident adolescent were sampled between 2009/2010 and 2011/2012. Measures included 1) potential structural drivers of HIV infection such as poverty and community violence; 2) HIV risk behaviours; 3) hypothesized psychosocial mediating factors; and 4) types of social protection involving cash and care. Using gender-disaggregated analyses, longitudinal mediation models were tested for potential main and moderating effects of social protection. Structural drivers were associated with increased onset of adolescent HIV risk behaviour (psocial protection were associated with reductions in HIV risk behaviour and psychosocial deprivations. In addition, cash social protection moderated risk pathways: for adolescent girls and boys experiencing more acute structural deprivation, social protection had the greatest associations with HIV risk prevention (e.g. moderation effects for girls: B=-0.08, psocial protection has the greatest prevention effects for the most vulnerable. Social protection comprising unconditional cash plus care was associated with reduced risk pathways through moderation and main effects, respectively. Our findings suggest the importance of social protection within a combination package of HIV

Science & education: Genetic analysis of winter social structure and social traits in a migratory sparrow & teaching argumentation in STEM education

Science.gov (United States)

Arnberg, Nina N.

Stable social organization in a wide variety of organisms has been linked to kinship, which can minimize conflict due to the indirect fitness benefits from cooperating with relatives. In birds, kin selection has been mostly studied in the context of reproduction or in species that are social year round. Many birds however are migratory and the role of kinship in the winter societies of these species is virtually unexplored. A previous study detected striking social complexity and stability in wintering populations of migratory golden-crowned sparrows (Zonotrichia atricapilla)---individuals repeatedly form close associations with the same social partners, including across multiple winters. In chapter one I test the possibility that kinship might be involved in these close and stable social affiliations. I examine the relationship between kinship and social structure for two of the consecutive wintering seasons from the previous study. I found no evidence that social structure was influenced by kinship---relatedness between most pairs of individuals was at most that of first cousins (and mostly far lower) and Mantel tests revealed no relationship between kinship and pairwise interaction frequency. Kinship also failed to predict social structure in more fine-grained analyses, including analyses of each sex separately (in the event that sex-biased migration might limit kin selection to one sex) and separate analyses for each social community. The complex winter societies of golden-crowned sparrows appear to be based on cooperative benefits unrelated to kin selection. Although the complex social structure detected in wintering golden-crowned sparrows is not predicted by kinship, genetic variation may play a role in variation of winter social traits. In chapter two, I investigate the genetic causes of variation in fitness-related traits in a winter population of golden-crowned sparrows. Individuals show great variation in morphological and behavioral traits that may play

2004-06-01

Full Text Available Abstract Background It has been proposed that greater availability of primary medical care practitioners (GPs contributes to better population health. We evaluated whether measures of the supply and structure of primary medical services are associated with health and health care indicators after adjusting for confounding. Methods Data for the supply and structure of primary medical services and the characteristics of registered patients were analysed for 99 health authorities in England in 1999. Health and health care indicators as dependent variables included standardised mortality ratios (SMR, standardised hospital admission rates, and conceptions under the age of 18 years. Linear regression analyses were adjusted for Townsend score, proportion of ethnic minorities and proportion of social class IV/ V. Results Higher proportions of registered rural patients and patients ≥ 75 years were associated with lower Townsend deprivation scores, with larger partnership sizes and with better health outcomes. A unit increase in partnership size was associated with a 4.2 (95% confidence interval 1.7 to 6.7 unit decrease in SMR for all-cause mortality at 15–64 years (P = 0.001. A 10% increase in single-handed practices was associated with a 1.5 (0.2 to 2.9 unit increase in SMR (P = 0.027. After additional adjustment for percent of rural and elderly patients, partnership size and proportion of single-handed practices, GP supply was not associated with SMR (-2.8, -6.9 to 1.3, P = 0.183. Conclusions After adjusting for confounding with health needs of populations, mortality is weakly associated with the degree of organisation of practices as represented by the partnership size but not with the supply of GPs.

2015-08-01

To describe associations between pregnancy rates in adolescence and socioeconomic and social responsibility indicators in the municipalities of the State of Minas Gerais, Southeast of Brazil, in the year of 2010. Ecological study using data from the Brazilian Live Birth Information System (SINASC). The percentage of live births to adolescent mothers (LBAM) for each municipality was calculated based on the quotient between number of born alive infants of mothers aged 10-19 years old and total number of live births in the year of 2010. Fully Bayesian models were used to obtain the percentages of LBAM adjusted for spatial effects and to assess possible associations with socioeconomic and social responsibility indicators. The crude percentage of LBAM for the total number of live births in the municipalities of Minas Gerais in 2010 ranged from 0 to 46.4%, with median percentage being 19.6% and the first and third quartiles being 15.6 and 23.1%, respectively. This study has demonstrated a close relationship between adolescent pregnancy and socioeconomic indicators. LBAM percentages were found to be higher in municipalities with low population density, low human development index and other low development indicators. The strong relationship between LBAM percentages and socioeconomic indicators suggests that adolescent pregnancy is more a social than a biological problem. Therefore, programs and actions should go beyond sexual education and information on preventive health methods.

Social and Structural Patterns of Drought-Related Water Conservation and Rebound

Science.gov (United States)

Gonzales, Patricia; Ajami, Newsha

2017-12-01

Water use practices and conservation are the result of complex sociotechnical interactions of political, economic, hydroclimatic, and social factors. While the drivers of water demand have been extensively studied, they have traditionally been applied to models that assume stationary relationships between these various factors, and usually do not account for potential societal changes in response to increased scarcity awareness. For example, following a period of sustained low demand such as during a drought, communities often increase water use during a hydrologically wet period, a phenomenon known as "rebounding" water use. Previous experiences show the extent of this rebound is not a straightforward function of policy and efficiency improvements, but may also reflect short-term or long-lasting change in community behavior, which are not easily captured by models that assume stationarity. In this work, we develop a system dynamics model to represent water demand as a function of both structural and social factors. We apply this model to the analysis of three diverse water utilities in the San Francisco Bay Area between 1980 and 2017, identifying drought response trends and drivers over time. Our model is consistent with empirical patterns and historical context of water use in California, and provides important insights on the rebound phenomenon that can be extended to other locations. This comparative assessment indicates that policies, public outreach, and better data availability have played a key role in raising public awareness of water scarcity, especially with the raise of the internet era in recent years.

The "sociotype" construct: Gauging the structure and dynamics of human sociality.

Directory of Open Access Journals (Sweden)

Pedro C Marijuán

Full Text Available Exploring the pertinence of a "sociotype" construct, established along the conceptual chain genotype-phenotype-sociotype, is the essential purpose of the present paper. Further, by following the sociotype's conceptual guidelines, a new psychometric indicator has been developed in order to gauge the level of social interaction around each individual-the sociotype questionnaire (SOCQ. A first version of this questionnaire has been elaborated by gathering data about the different classes of social bonds (family, friends, acquaintances, and work/study colleagues in general population and about the dynamic update of these bonds via face-to-face conversation and other modes of interaction. A specific fieldwork was undertaken, involving 1,075 participants, all of them Spanish adults (with diverse social and regional backgrounds. The data obtained were analyzed by means of the correlational method with an analytical cross-sectional design: the number of factors and the consistency and reliability of the resulting scales were evaluated and correlated. The new sociotype indicator resulting from that fieldwork, in spite of its limitations, seems to be valid and reliable, as well as closely associated with widely used metrics of loneliness and psychological distress. It is interesting that the construct noticeably varies throughout the life course and circumstances of individuals, based on their gender and age, and adjusting to the different situations of social networking. This is the first study, to the best of our knowledge, which has tried to reach both a theoretical and an operational formulation of the sociotype construct, by establishing an ad hoc psychometric questionnaire. We think that the information provided by this operational definition opens a new direction of work that could be useful to guide the development and evaluation of programs aimed at improving and strengthening social networking in people at risk, especially for the elderly.

So it seems to be accurate in the future national studies in order to better understand the aging population, especially women and other fragile groups to and also be designed to the prevention and treatment interventions, with attention to fragile women disabilities and their lack of financial security and will also feel the need to pay special attention to young women before and after aging.

To examine the impact of Seguro Popular (Mexican social health insurance for the poor; SP) on diabetes and hypertension care, intermediate process indicators for older adults (>50 years): pharmacological treatment, blood glucose tests, the use of complementary and alternative medicine (CAM), and adherence to their nutrition and exercise program. (CAM was defined as products or practices that were not part of the medical standard of care.) Repeated cross-sectional surveys from Encuesta Nacional de Salud y Nutrición (Mexican Health and Nutrition Survey, ENSANUT), a nationally representative health and nutrition survey sampling N = 45,294 older adults in 2000, N = 45,241 older adults in 2005-2006, and N = 46,277 older adults in 2011-2012. Fixed-effects instrumental variable (FE-IV) repeated cross-sectional at the individual level with municipality fixed-effects estimation was performed. We found a marginally significant effect of SP on the use of insulin and oral agents (40 percentage points). Contrary to that expected, no other significant differences were found for diabetes or hypertension treatment and care indicators. Social health insurance for the poor improved some but not all health care process indicators among diabetic and hypertensive older people in Mexico. © Health Research and Educational Trust.

Brown, Louis D; Tang, Xiaohui; Hollman, Ruth L

2014-03-01

Self-help support groups are indigenous community resources designed to help people manage a variety of personal challenges, from alcohol abuse to xeroderma pigmentosum. The social exchanges that occur during group meetings are central to understanding how people benefit from participation. This paper examines the different types of social exchange behaviors that occur during meetings, using two studies to develop empirically distinct scales that reliably measure theoretically important types of exchange. Resource theory informed the initial measurement development efforts. Exploratory factor analyses from the first study led to revisions in the factor structure of the social exchange scales. The revised measure captured the exchange of emotional support, experiential information, humor, unwanted behaviors, and exchanges outside meetings. Confirmatory factor analyses from a follow-up study with a different sample of self-help support groups provided good model fit, suggesting the revised structure accurately represented the data. Further, the scales demonstrated good convergent and discriminant validity with related constructs. Future research can use the scales to identify aspects of social exchange that are most important in improving health outcomes among self-help support group participants. Groups can use the scales in practice to celebrate strengths and address weaknesses in their social exchange dynamics.

Physico-Chemical and Structural Interpretation of Discrete Derivative Indices on N-Tuples Atoms

Directory of Open Access Journals (Sweden)

Oscar Martínez-Santiago

2016-05-01

Full Text Available This report examines the interpretation of the Graph Derivative Indices (GDIs from three different perspectives (i.e., in structural, steric and electronic terms. It is found that the individual vertex frequencies may be expressed in terms of the geometrical and electronic reactivity of the atoms and bonds, respectively. On the other hand, it is demonstrated that the GDIs are sensitive to progressive structural modifications in terms of: size, ramifications, electronic richness, conjugation effects and molecular symmetry. Moreover, it is observed that the GDIs quantify the interaction capacity among molecules and codify information on the activation entropy. A structure property relationship study reveals that there exists a direct correspondence between the individual frequencies of atoms and Hückel’s Free Valence, as well as between the atomic GDIs and the chemical shift in NMR, which collectively validates the theory that these indices codify steric and electronic information of the atoms in a molecule. Taking in consideration the regularity and coherence found in experiments performed with the GDIs, it is possible to say that GDIs possess plausible interpretation in structural and physicochemical terms.

Maryam Mehrabi

2016-01-01

Full Text Available This study is a sociological analysis of the three dimensions of social structure including institutional, relational, and embodied structures that have an impact on the individuals’ deviant behaviors in the society. The authors used a mix method to analyze the qualitative and quantitative data of 402 high risk abandoned substance users in 2008 in Tehran, capital city of Iran. The leading reasons of substance use were categorized into four fundamental themes as follows: stress, deviant social networks, and low social capital and weak social support sources. In addition, the epidemiology model of regression analysis provides a brief explanation to assess the association between the demographical and etiological variables, and the drug users’ deviant behaviors. In sum, substance use is discussed as a deviant behavior pattern which stems from a comorbidity of weak social structures.

2010-06-01

We study the empirical consistency of survey based (micro level) indicators of social capital and local government performance on the one, and municipality based (aggregate level) measures of these two concepts on the other hand. Knowledge about the behavior of these indicators is helpful for evaluating the value of studies carried out in isolated contexts, that is, with access to data on either, but not both, levels. The method is by comparing data collected by Statistics Belgium on Flemish municipalities, to data collected at citizen level by means of a face-to-face survey. The available evidence supplies at best a meager basis for presupposing a shared component of the indicators under study.

We investigate two paradigms for studying the evolution of cooperation-Prisoner's Dilemma and Snowdrift game in an online friendship network, obtained from a social networking site. By structural analysis, it is revealed that the empirical social network has small-world and scale-free properties. Besides, it exhibits assortative mixing pattern. Then, we study the evolutionary version of the two types of games on it. It is found that cooperation is substantially promoted with small values of game matrix parameters in both games. Whereas the competent cooperators induced by the underlying network of contacts will be dramatically inhibited with increasing values of the game parameters. Further, we explore the role of assortativity in evolution of cooperation by random edge rewiring. We find that increasing amount of assortativity will to a certain extent diminish the cooperation level. We also show that connected large hubs are capable of maintaining cooperation. The evolution of cooperation on empirical networks is influenced by various network effects in a combined manner, compared with that on model networks. Our results can help understand the cooperative behaviors in human groups and society.

We introduce a conceptual framework with social relations as the main concept and the structure and the function of social relations as subconcepts. The structure of social relations covers aspects of formal relations and social network. The function of social relations covers social support......, social anchorage and relational strain. We use this conceptual framework to describe social relations in the Danish population, with questionnaire data from the Danish Longitudinal Health Behaviour Study including a random sample of each of the age groups 25-, 50-, 60-and 70-year olds, N = 2......,011. The postal questionnaires were answered by a random sample in each of the age groups. The results show marked age and gender differences in both the structure and the function of social relations. The social network, measured as weekly contacts, weakens with age and so does instrumental support. Emotional...

Social structure and social capital are important variables for public health strategies seeking to prevent smoking among adolescents. The purpose of this study was to examine the relationships between social structure, social capital and changes in smoking status from the 8th to 9th grade in Taiwan. Data were obtained from the Child and Adolescent Behaviors in Long-term Evolution (CABLE) project. The study analyzed a final sample of 1937 students (50.7% female). Each layer of social structure was associated with a particular form of social capital. Students whose parents were married and living together had higher family social capital. After controlling for background variables, the social structure variable of friends who smoke was significantly associated with changes in smoking status. Students reporting more school attachment were less likely to start smoking. Students with higher parental supervision was associated with less chance of being a consistent smoker, whereas participation of social organization outside of school was associated with continued smoking. Attending school club was associated with higher probability of smoking cessation. Smoking prevention and intervention strategies aimed at junior high school students should be tailored to the particular form of social capital important for each type of smoking status.

Sakai, Shogo; Kita, Yuki

2013-07-01

The structures and local aromaticity of some conjugated polycyclic hydrocarbons (from the butadienoid, acene, and phenylene series) are studied using ab initio MO and density functional methods. The aromaticities of the molecules are estimated using three indices: the nucleus-independent chemical shift (NICS), the harmonic oscillator model of aromaticity (HOMA), and the index of deviation from aromaticity (IDA). Assessment of the relationships between the structures and the aromatic indices shows that the IDA values correspond best to the characteristics of the conjugated polycyclic hydrocarbon structures.

Metzler, Rebecca A; Jones, Joshua A; D'Addario, Anthony J; Galvez, Enrique J

2017-02-01

The inner layer of many bivalve and gastropod molluscs consists of iridescent nacre, a material that is structured like a brick wall with bricks consisting of crystalline aragonite and mortar of organic molecules. Myostracal layers formed during shell growth at the point of muscle attachment to the shell can be found interspersed within the nacre structure. Little has been done to examine the effect the myostracal layer has on subsequent nacre structure. Here we present data on the structure of the myostracal and nacre layers from a bivalve mollusc, Pinctada fucata . Scanning electron microscope imaging shows the myostracal layer consists of regular crystalline blocks. The nacre before the layer consists of tablets approximately 400 nm thick, while after the myostracal layer the tablets are approximately 500 nm thick. A new technique, imaging polarimetry, indicates that the aragonite crystals within the nacre following the myostracal layer have greater orientation uniformity than before the myostracal layer. The results presented here suggest a possible interaction between the myostracal layer and subsequent shell growth.

Full Text Available The author undertakes the first in the Russian and, maybe, world scientific literature sociological research into the disaster of the Titanic. It is researched the social and class structure of the community of passengers of the Titanic on the ground of statistical data on prices of tickets and on occupations of passengers. This data discovers that passengers of the Titanic belonged to different social classes. The author researched the connection between social and class structure and chances of survival. The destiny of passengers and the crew were determined by regulated and unregulated chances of survival. The regulated chances of survival were connected with the politics of the command of the Titanic, that was foremost pointed to, firstly, the rescue of passengers (but not the crew, secondly, passengers of 1st and 2nd classes (but not passengers of 3rd class and thirdly, women and children (but not men. The unregulated chances of survival were connected with ethnic, linguistic and age-related characteristics of passengers. The author considers the disaster of the Titanic within the framework of globalization.

Social support and social networks can elucidate important structural and functional aspects of social relationships that are associated with health-promoting behaviors, including Physical Activity (PA) and weight. A growing number of studies have investigated the relationship between social support, social networks, PA and obesity specifically among African Americans; however, the evidence is mixed and many studies focus exclusively on African American women. Most studies have also focused on either functional or structural aspects of social relationships (but not both) and few have objectively measured moderate-to-vigorous physical activity (MVPA) and body mass index (BMI). Cross-sectional surveys of adult African American men and women living in two low-income predominantly African American neighborhoods in Pittsburgh, PA (N = 799) measured numerous structural features as well as functional aspects of social relationships. Specifically, structural features included social isolation, and social network size and diversity. Functional aspects included perceptions of social support for physical activity from the social network in general as well as from family and friends specifically. Height, weight, and PA were objectively measured. From these, we derived Body Mass Index (BMI) and moderate-to-vigorous physical activity (MVPA). All regression models were stratified by gender, and included age, income, education, employment, marital status, physical limitations, and a neighborhood indicator. Greater social isolation was a significant predictor of lower BMI among men only. Among women only, social isolation was significantly associated with increased MVPA whereas, network diversity was significantly associated with reduced MVPA. Future research would benefit from in-depth qualitative investigations to understand how social networks may act to influence different types of physical activity among African Americans, as well as understand how they can be possible levers

Social representations of adolescents on quality of life: structurally-based study

Full Text Available This study sought to conduct a comparatively analysis and describe the contents of the structure of the social representations of adolescents on quality of life. It involves descriptive, quantitative research, with the benchmark of a structural approach to social representations. The informants included 316 adolescents from three public schools in Jequié in the State of Bahia. The Spontaneous Word-Choice Eliciting Technique using the key expression "Quality of Life" was used for data collection. The responses were processed using Evoc 2003 software, which generated the Four-House Chart. The results reveal the core nucleus of the terms: healthy eating; physical activity; money; and sex. In the 1st outer circle, the words absence of disease, condoms, liberty, marijuana, housing, work and living well are featured. In the 2nd outer circle, there appeared the words difficulty, family, peace and power, and the contrasting elements of well-being and soccer. The overall consensus is that adolescents associate quality of life with sports and other healthy behavior activities, and are influenced by the desires and curiosities of adolescence.

Structure model of energy efficiency indicators and applications

2007-01-01

For the purposes of energy conservation and environmental protection, the government of Taiwan has instigated long-term policies to continuously encourage and assist industry in improving the efficiency of energy utilization. While multiple actions have led to practical energy saving to a limited extent, no strong evidence of improvement in energy efficiency was observed from the energy efficiency indicators (EEI) system, according to the annual national energy statistics and survey. A structural analysis of EEI is needed in order to understand the role that energy efficiency plays in the EEI system. This work uses the Taylor series expansion to develop a structure model for EEI at the level of the process sector of industry. The model is developed on the premise that the design parameters of the process are used in comparison with the operational parameters for energy differences. The utilization index of production capability and the variation index of energy utilization are formulated in the model to describe the differences between EEIs. Both qualitative and quantitative methods for the analysis of energy efficiency and energy savings are derived from the model. Through structural analysis, the model showed that, while the performance of EEI is proportional to the process utilization index of production capability, it is possible that energy may develop in a direction opposite to that of EEI. This helps to explain, at least in part, the inconsistency between EEI and energy savings. An energy-intensive steel plant in Taiwan was selected to show the application of the model. The energy utilization efficiency of the plant was evaluated and the amount of energy that had been saved or over-used in the production process was estimated. Some insights gained from the model outcomes are helpful to further enhance energy efficiency in the plant

Impact of functional and structural social relationships on two year depression outcomes: A multivariate analysis.

Davidson, Sandra K; Dowrick, Christopher F; Gunn, Jane M

2016-03-15

High rates of persistent depression highlight the need to identify the risk factors associated with poor depression outcomes and to provide targeted interventions to people at high risk. Although social relationships have been implicated in depression course, interventions targeting social relationships have been disappointing. Possibly, interventions have targeted the wrong elements of relationships. Alternatively, the statistical association between relationships and depression course is not causal, but due to shared variance with other factors. We investigated whether elements of social relationships predict major depressive episode (MDE) when multiple relevant variables are considered. Data is from a longitudinal study of primary care patients with depressive symptoms. 494 participants completed questionnaires at baseline and a depression measure (PHQ-9) two years later. Baseline measures included functional (i.e. quality) and structural (i.e. quantity) social relationships, depression, neuroticism, chronic illness, alcohol abuse, childhood abuse, partner violence and sociodemographic characteristics. Logistic regression with generalised estimating equations was used to estimate the association between social relationships and MDE. Both functional and structural social relationships predicted MDE in univariate analysis. Only functional social relationships remained significant in multivariate analysis (OR: 0.87; 95%CI: 0.79-0.97; p=0.01). Other unique predictors of MDE were baseline depression severity, neuroticism, childhood sexual abuse and intimate partner violence. We did not assess how a person's position in their depression trajectory influenced the association between social relationships and depression. Interventions targeting relationship quality may be part of a personalised treatment plan for people at high risk due of persistent depression due to poor social relationships.

The nursing workplace imposes significantly more stress on its employees than other workplace settings. Organizational resources, both physical and psychological, have been recognized in prior studies as important alleviators of nursing workplace stress. Whereas physical resources are less difficult to manipulate because of their tangibility, psychological resources, particularly psychological support from colleagues, are typically not deployed to greatest effect. This article investigated the alleviation of nursing work stress using resources already extant in coworker social networks. Researchers conducted a survey in a dialysis department at a medical center located in Taipei City, Taiwan. This survey measured nurse work stress, satisfaction, organizational citizenship behavior (OCB) and social network structures. Researchers employed UCINET to analyze the network structure data, which were in dyadic matrix format to estimate nurse network centralities and used partial least squares analysis to estimate research construct path coefficients and test extrapolated hypotheses. The level of OCB induced by nurse social ties was satisfactory and did not only directly increased work satisfaction but also alleviated work stress, which indirectly boosted work satisfaction. Findings suggest that managers may be able to use social network analysis to identify persons appropriate to conduct the distribution of organizational resources. Choosing those with multiple social connections can help distribute resources effectively and induce higher OCB levels within the organization. In addition, staff with strong friendship network connections may provide appropriate psychological resources (support) to coworkers. If those with high friendship network centrality receive proper counseling training, they should be in a good position to provide assistance when needed.

Can Social Comparison Feedback Affect Indicators of Eco-Friendly Travel Choices? Insights from Two Online Experiments

Directory of Open Access Journals (Sweden)

Rouven Doran

2017-01-01

Full Text Available Two online experiments explored the effects of social comparison feedback on indicators of eco-friendly travel choices. It was tested whether the chosen indicators are sensitive to the information conveyed, and if this varies as a function of in-group identification. Study 1 (N = 134 focused on unfavourable feedback (i.e., being told that one has a larger ecological footprint than the average member of a reference group. People who received unfavourable feedback reported stronger intentions to choose eco-friendly travel options than those who received nondiscrepant feedback, when in-group identification was high (not moderate or low. Perceived self- and collective efficacy were not associated with the feedback. Study 2 (N = 323 extended the focus on favourable feedback (i.e., being told that one has a smaller ecological footprint than the average member of a reference group. Neither unfavourable nor favourable feedback was associated with behavioural intentions, self- or collective efficacy. This means that Study 2 failed to replicate the finding of Study 1 that behavioural intentions were associated with unfavourable feedback, given that in-group identification is high. The findings are discussed in light of the existing literature. Suggestions are made for future studies investigating social comparison feedback as a means to motivate people to make eco-friendly travel choices.

Aiming to merge traffic flow analysis with evolutionary game theory, we investigated the question of whether such structures can be formed from frequent lane changes in usual traffic flow without any explicit bottlenecks. In our model system, two classes of driver-agents coexist: C-agents (cooperative strategy) always remain in the lane they are initially assigned, whereas D-agents (defective strategy) try to change lanes to move ahead. In relatively high-density flows, such as the metastable and high-density phases, we found structures that correspond to either n-person prisoner dilemma (n-PD) games or quasi-PD games. In these situations, lane changes by D-agents create heavy traffic jams that reduce social efficiency. (paper)

Social transmission of memory and its consequence on collective memory have generated enduring interdisciplinary interest because of their widespread significance in interpersonal, sociocultural, and political arenas. We tested the influence of 3 key factors-emotional salience of information, group structure, and information distribution-on mnemonic transmission, social contagion, and collective memory. Participants individually studied emotionally salient (negative or positive) and nonemotional (neutral) picture-word pairs that were completely shared, partially shared, or unshared within participant triads, and then completed 3 consecutive recalls in 1 of 3 conditions: individual-individual-individual (control), collaborative-collaborative (identical group; insular structure)-individual, and collaborative-collaborative (reconfigured group; diverse structure)-individual. Collaboration enhanced negative memories especially in insular group structure and especially for shared information, and promoted collective forgetting of positive memories. Diverse group structure reduced this negativity effect. Unequally distributed information led to social contagion that creates false memories; diverse structure propagated a greater variety of false memories whereas insular structure promoted confidence in false recognition and false collective memory. A simultaneous assessment of network structure, information distribution, and emotional valence breaks new ground to specify how network structure shapes the spread of negative memories and false memories, and the emergence of collective memory.

Structural Modeling for the Comparison Indicators in Various Electricity Generating Systems

International Nuclear Information System (INIS)

Comparison indicators of various power systems can be yielded by solving a multicriteria decision-making (MCDM) problem. In reality, there are different grades of interdependence among the decision elements (e.g., decision goal, decision criteria, and decision alternatives). In our previous work, based on an analytic hierarchy process (AHP) technique, an independence model was developed for the comparison indicators under the assumption that there is no interdependence among the decision elements. For handling different interdependence phenomena (e.g., independence, inner dependence, outer dependence, feedback effect, a combination thereof) among the decision elements, one of the simplest graph structures was investigated on the basis of an analytic network process (ANP) technique. In the present work, the main objective is to study an assessment model with a high grade of interactions among the decision elements. Comparison indicators (e.g., weighting factors, overall priority scores, and risk attitudes towards a nuclear power plant) for seven power generation systems are obtained

Ubuntu and Social Capital factors in Family Businesses

Full Text Available The current study is an investigation of social capital, and more particularly the support of the concept of ubuntu in large family businesses in South Africa. Insights into the social responsibility activities of some of the largest family businesses in South Africa, obtained through semi-structured interviews, clearly indicate the important role which the social responsibility ubuntu activities of these businesses play in caring for the community. As South Africa has a mainly “individualistic economic community”, it is interesting to observe how the collectivistic notion of ubuntu is practised in the social responsibility activities of family business groups. Key words and phrases: ubuntu, social responsibility, social capital, family business, conditional matrix

The purpose of this case study is to analyze the correlations between the Audit Committee and structural indicators. Considering the achievement of the objectives proposed in this research, our research is based on a deductive approach from general aspects to particular aspects that combines quantitative and qualitative studies. Theoretical knowledge is used for a better understanding of a phenomenon and not for making assumptions. Thus, in order to achieve our study, we selected 25 companies listed on Berlin Stock Exchange. Following this study, we concluded that the role of the audit committee is crucial.

Surviving in two worlds: social and structural violence of Thai female injecting drug users.

Thai females injecting drugs are ensnared in a web of problems arising from forms of prejudice that magnify their vulnerability. They are vulnerable, at risk, and exposed to a high degree of social suffering. This paper aims to elucidate how social production and structural violence combine to shape the lives of these women. Using a qualitative methodology, two focus groups with 5 key informants and in-depth interviews involving a total of 35 women injecting drugs were conducted in Bangkok. The findings reveal that the structural environment that directly impacts upon these women's lives becomes the reason for their suffering. The structural environment puts these women at risk of violence in numerous social settings in which these women engage as well as generating tension at a subjective level (i.e. the habitus) of these women. Thai female injecting drug users are trapped in a difficult tension between the demands for being Thai women seeking to exist in the masculine world of drug use but at the same time meeting Thai society's expectations of womanhood. Unequal gender relations are manifest in the everyday violence that women face in the drug community, culminating in the essential nature of women being questioned, undermined and threatened. Living in the drug community, women are subjected to violence and harassment, and gendered brutality by intimate partners. In conclusion, the social suffering that Thai female injecting drug users find themselves confronting is confined to dilemmas cause by tensions between drug use and the overriding gender habitus.

Full Text Available The article, using historic and sociological material, presents genesis, dialectics and the role of cadet education of the imperial Russia in the social structure of the society, its weak and strong aspects, determines major stratified features of its graduates. The author notes that the realization of the practice of professional socialization in cadet corps in certain historical period is determined by the social conditions and the factors of the development of the society, its structure and environment, reproducing the modal personality of the future officer. The professional environment of the cadet education in the imperial Russia is defined as closed, line, self-organizing system. Such environment provided the graduates with high social status and prestige in different fields, defined by generic characteristics (affiliation to nobility. Along with high educational and cultural level, modal personality of the graduate is characterized by aloofness from the juniors and subordinates, individualism and careerism, certain closedness towards one’s nation and other social groups.

Social structure of a semi-free ranging group of mandrills (Mandrillus sphinx: a social network analysis.

Directory of Open Access Journals (Sweden)

Céline Bret

Full Text Available The difficulty involved in following mandrills in the wild means that very little is known about social structure in this species. Most studies initially considered mandrill groups to be an aggregation of one-male/multifemale units, with males occupying central positions in a structure similar to those observed in the majority of baboon species. However, a recent study hypothesized that mandrills form stable groups with only two or three permanent males, and that females occupy more central positions than males within these groups. We used social network analysis methods to examine how a semi-free ranging group of 19 mandrills is structured. We recorded all dyads of individuals that were in contact as a measure of association. The betweenness and the eigenvector centrality for each individual were calculated and correlated to kinship, age and dominance. Finally, we performed a resilience analysis by simulating the removal of individuals displaying the highest betweenness and eigenvector centrality values. We found that related dyads were more frequently associated than unrelated dyads. Moreover, our results showed that the cumulative distribution of individual betweenness and eigenvector centrality followed a power function, which is characteristic of scale-free networks. This property showed that some group members, mostly females, occupied a highly central position. Finally, the resilience analysis showed that the removal of the two most central females split the network into small subgroups and increased the network diameter. Critically, this study confirms that females appear to occupy more central positions than males in mandrill groups. Consequently, these females appear to be crucial for group cohesion and probably play a pivotal role in this species.

Full Text Available This study aims to determined (1 the form of social structure that occur in groups of flying fish fishermen and (2 the rights and duties between the punggawa and sawi inside the social structure in flying fish fisher groups at Bontomarannu Village of South Galesong District, Takalar. The basic method of this research was descriptive method with qualitative approach, while the strategy was a case study. The research was conducted in the Bontomarannu Villages District of South Galesong as one of the flying fish fisher group who still use the traditional way. Determination of informants conducted snowball sampling where there were 35 informants were used in this study. The results showed that the shape of the social structure of the punggawa sawi in a group of flying fish fisher form of domination and legitimacy of the role played by the punggawa being the highest position in the social relations. The strength of the social structure between the punggawa and sawi belong to the powerful force that created rights and duties of each role and status they have in the flying fish fisher groups. Rights and duties were not only applicable in the employment relationship alone, but more deeply into the journey of life both within the coastal communities in the Bontomarannu Village.

The objective of this study was to examine the relationship between social capital and health among Chinese immigrants. The sample included 101 older Chinese immigrants aged 60 to 96 who were recruited in 2013 in a city on the Canadian prairies. Participant completed a questionnaire assessing their structural and cognitive social capital (views on community, trust and reciprocity, civic participation, social networks and support, and social participation), physical and mental health status (SF-36), and sociodemographic characteristics. Findings indicate that Chinese seniors overall obtained low levels of social capital on all social capital dimensions. Social networks and support (a structural social capital indicator) was significantly positively associated with mental health (β = .31, p social capital is potentially more promising than ensuring cognitive social capital in terms of providing physical and mental health benefits to older adults from Chinese background.

Integrating social networks and human social motives to achieve social influence at scale

The innovations of science often point to ideas and behaviors that must spread and take root in communities to have impact. Ideas, practices, and behaviors need to go from accepted truths on the part of a few scientists to commonplace beliefs and norms in the minds of the many. Moving from scientific discoveries to public good requires social influence. We introduce a structured influence process (SIP) framework to explain how social networks (i.e., the structure of social influence) and human social motives (i.e., the process of social influence wherein one person’s attitudes and behaviors affect another’s) are used collectively to enact social influence within a community. The SIP framework advances the science of scientific communication by positing social influence events that consider both the “who” and the “how” of social influence. This framework synthesizes core ideas from two bodies of research on social influence. The first is network research on social influence structures, which identifies who are the opinion leaders and who among their network of peers shapes their attitudes and behaviors. The second is research on social influence processes in psychology, which explores how human social motives such as the need for accuracy or the need for affiliation stimulate behavior change. We illustrate the practical implications of the SIP framework by applying it to the case of reducing neonatal mortality in India. PMID:25225373
