An overall statistic for testing symmetry in social interactions

The present work focuses the attention on the skew-symmetry index as a measure of social reciprocity. This index is based on the correspondence between the amount of behaviour that each individual addresses to its partners and what it receives from them in return. Although the skew-symmetry index enables researchers to describe social groups, statistical inferential tests are required. The main aim of the present study is to propose an overall statistical technique for testing symmetry in experimental conditions, calculating the skew-symmetry statistic (Φ) at group level. Sampling distributions for the skew- symmetry statistic have been estimated by means of a Monte Carlo simulation in order to allow researchers to make statistical decisions. Furthermore, this study will allow researchers to choose the optimal experimental conditions for carrying out their research, as the power of the statistical test has been estimated. This statistical test could be used in experimental social psychology studies in which researchers may control the group size and the number of interactions within dyads.

A statistical procedure for testing social reciprocity at group, dyadic and individual levels

This paper examines statistical analysis of social reciprocity, that is, the balance between addressing and receiving behaviour in social interactions. Specifically, it focuses on the measurement of social reciprocity by means of directionality and skew-symmetry statistics at different levels. Two statistics have been used as overall measures of social reciprocity at group level: the directional consistency and the skew-symmetry statistics. Furthermore, the skew-symmetry statistic allows social researchers to obtain complementary information at dyadic and individual levels. However, having computed these measures, social researchers may be interested in testing statistical hypotheses regarding social reciprocity. For this reason, it has been developed a statistical procedure, based on Monte Carlo sampling, in order to allow social researchers to describe groups and make statistical decisions.

How Social Dominance Orientation affects union participation: The role of union identification and perceived union instrumentality

Bridging social dominance theory and labour studies, this field study investigated the mechanisms underpinning the relationship between rejection of group-based domination and participation in union activities. Respondents (N = 135) were members of a public sector union in California, that is, a hierarchy-attenuating institution. Results revealed that union identification mediated the negative relationship between social dominance orientation and active union participation. Moreover, the mediational effect of union identification was moderated by perceived union instrumentality (i.e. outcome- and process-based benefits afforded by the union), indicating that the relationship between union identification and participation was stronger among those union members who consider that the union affects workplace justice. The findings reveal the importance of both identity-based and instrumental motivations underlying union participation. The novelty of applying social dominance theory to union behaviour is underscored.

Quantifying Social Asymmetric Structures

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 paper describes a mathematical procedure for analyzing dyadic interactions in a social system. The proposed method mainly consists of decomposing asymmetric data into their symmetrical and skew-symmetrical parts. A quantification of skew-symmetry for a social system can be obtained by dividing the norm of the skew-symmetrical matrix by the norm of the asymmetric matrix. This calculation makes available to researchers a quantity related to the amount of dyadic reciprocity. Regarding 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.

Measuring and making decisions for social reciprocity

Social reciprocity may explain certain emerging psychological processes, which are likely to be founded on dyadic relations. Although some indices and statistics have been proposed to measure and make statistical decisions regarding social reciprocity in groups, these were generally developed to identify association patterns rather than to quantify the discrepancies between what each individual addresses to his/her partners and what is received from them in return. Additionally, social researchers are not only interested in measuring groups at the global level, since dyadic and individual measurements are also necessary for a proper description of social interactions. This study is concerned with a new statistic for measuring social reciprocity at the global level and with decomposing it in order to identify those dyads and individuals which account for a significant part of asymmetry in social interactions. In addition to a set of indices some exact analytical results are derived and a way of making statistical decisions is proposed.

Reliability and validity of nonverbal thin slices in social interactions

Four studies investigated the reliability and validity of thin slices of nonverbal behavior from social interactions including (1) how well individual slices of a given behavior predict other slices in the same interaction; (2) how well a slice of a given behavior represents the entirety of that behavior within an interaction; (3) how long a slice is necessary to sufficiently represent the entirety of a behavior within an interaction; (4) which slices best capture the entirety of behavior, across different behaviors; and (5) which behaviors (of six measured behaviors) are best captured by slices. Notable findings included strong reliability and validity for thin slices of gaze and nods, and that a 1.5 min slice from the start of an interaction may adequately represent some behaviors. Results provide useful information to researchers making decisions about slice measurement of behavior.

The social protection between the light and the shadow. This article tries to reveal some subject formation traces facing itself and the society that it is inserted to discuss the Social Protection importance in Knowledge Economy as the Human potentialities expansion factor. The assumption is the connection between the individual and the world happens in a dynamic relation where the individual shapes the society and the society is shaped by the individual. So Fromm's Social Psychology (1941) is used to clarify the appearing of the fears and humans passions and Gorz's No material concept (2003).

Perceptions of intergroup bias : the roles of social projection and meta-stereotypes

Underlying intergroup perceptions include processes of social projection (perceiving personal traitslbeliefs in others, see Krueger 1998) and meta-stereotyping (thinking about other groups' perceptions of one's own group, see Vorauer et aI., 1998). Two studies were conducted to investigate social projection and meta-stereotypes in the domain of White-Black racial relations. Study 1, a correlational study, examined the social projection of prejudice and 'prejudiced' meta-stereotypes among Whites. Results revealed that (a) Whites socially projected their intergroup attitudes onto other Whites (and Blacks) [i.e., Whites higher in prejudice against Blacks believed a large percentage of Whites (Blacks) are prejudiced against Blacks (Whites), whereas Whites low in prejudice believed a smaller percentage of Whites (Blacks) are prejudiced]; (b) Whites held the meta:..stereotype that their group (Whites) is viewed by Blacks to be prejudiced; and (c) prejudiced meta-stereotypes may be formed through the social projection of intergroup attitudes (result of path-model tests). Further, several correlates of social projection and meta-stereotypes were identified, including the finding that feeling negatively stereotyped by an outgroup predicted outgroup avoidance through heightened intergroup anxiety. Study 2 replicated and extended these findings, investigating the social projection of ingroup favouritism and meta- and other-stereotypes about ingroup favouritism. These processes were examined experimentally using an anticipated intergroup contact paradigm. The goal was to understand the experimental conditions under which people would display the strongest social projection of intergroup attitudes, and when experimentally induced meta-stereotypes (vs. other-stereotypes; beliefs about the group 11 preferences of one's outgroup) would be most damaging to intergroup contact. White participants were randomly assigned to one of six conditions and received (alleged) feedback from a previously completed computer-based test. Depending on condition, this information suggested that: (a) the participant favoured Whites over Blacks; (b) previous White participants favoured Whites over Blacks; (c) the participant's Black partner favoured Blacks over Whites; (d) previous Black participants favoured Blacks over Whites; (e) the participant's Black partner viewed the participant to favour Whites over Blacks; or (£) Black participants previously participating viewed Whites to favour Whites over Blacks. In a defensive reaction, Whites exhibited enhanced social projection of personal intergroup attitudes onto their ingroup under experimental manipulations characterized by self-concept threat (i.e., when the computer revealed that the participant favoured the ingroup or was viewed to favour the ingroup). Manipulated meta- and otherstereotype information that introduced intergroup contact threat, on the other hand, each exerted a strong negative impact on intergroup contact expectations (e.g., anxiety). Personal meta-stereotype manipulations (i.e., when the participant was informed that her/ his partner thinks s/he favours the ingroup) exerted an especially negative impact on intergroup behaviour, evidenced by increased avoidance of the upcoming interracial interaction. In contrast, personal self-stereotype manipulations (i.e., computer revealed that one favoured the ingroup) ironically improved upcoming intergroup contact expectations and intentions, likely due to an attempt to reduce the discomfort of holding negative intergroup attitudes. Implications and directions for future research are considered.

Competência Social em contexto de carreira e autoconceito

A competência social é um construto multidimensional que abrange um conjunto de comportamentos aprendidos, socialmente aceites e que, deste modo, desempenha um papel fundamental no desenvolvimento humano em geral e, em particular, no funcionamento escolar e profissional, afetando as relações com os professores e pares e o sucesso académico e profissional (Lemos & Menezes, 2002). Por sua vez, o autoconceito, também descrito na literatura como um construto multidimensional que engloba um sistema de representações descritivas e avaliativas acerca do desempenho do self nos diferentes contextos e tarefas em que o sujeito se envolve, diz respeito à imagem que o sujeito tem de si próprio e aquilo que acredita ser (Veiga, 2006). A carreira é um exemplo de um processo sócio relacional (Blustein, 2011). Exige a capacidade do indivíduo para avaliar os conhecimentos de si e do meio, bem como para selecionar e implementar recursos sociais adequados para lidar com tarefas de carreira e desafios específicos. Tendo em consideração a falta de estudos teóricos e empíricos sobre a compreensão das competências sociais e do autoconceito no âmbito da carreira dos jovens adolescentes, este estudo tem como objetivo principal caracterizar as competências sociais em contexto de carreira e o autoconceito em alunos do 8º ano, bem como, analisar possíveis diferenças nos resultados em função de variáveis sociodemográficas. Além disso, pretende-se, ainda, analisar a influência do autoconceito nas competências sociais em contexto de carreira e vice-versa. Para o efeito, participaram neste estudo 306 estudantes de ambos os sexos, 163 raparigas (53,3%) e 143 rapazes (46,7%), com idades compreendidas entre 12 e 16 anos (M=13,28; DP=0,590). Estes jovens encontram-se a frequentar o 8º ano de escolaridade, em três estabelecimentos de ensino público da zona norte do país. Foram administrados dois questionários de auto relato, a Prova de Avaliação de Competência Social em contexto de Carreira (PACS-Car, Candeias, 2005 adaptada por Araújo & Taveira, 2009) para avaliar as competências sociais de carreira e, o Piers-Harris Children’s Self Concept Scale-2 (PHCSCS-2 – Piers & Herzberg, 2002, adaptado por Veiga, 2006), para avaliar o autoconceito. Os resultados indicam que os rapazes apresentam níveis mais elevados de desempenho pobre, ansiedade e popularidade, quando comparados com as raparigas e que os alunos mais novos apresentam níveis de desempenho excelente, aspeto comportamental e ansiedade superiores aos adolescentes mais velhos. Verificou-se, ainda, que as competências sociais em contexto de carreira parecem influenciar positivamente o autoconceito e vice-versa. São retiradas implicações para o processo de intervenção na carreira com jovens.

Responsabilidade social das organizações e satisfação no trabalho: estudo num call center

A presente dissertação tem como objectivo estudar a percepção dos colaboradores a respeito da Responsabilidade Social da Organização exercida pela organização onde trabalham e a relação desta com a Satisfação no Trabalho. Cento e sete colaboradores de um call center responderam a um questionário que incluía as escalas de Percepção de Responsabilidade Social, Satisfação no Trabalho e a escala de Call Center construída para este estudo. As hipóteses são, duas, verificar se quando maior a percepção de práticas socialmente responsáveis nas diferentes dimensões (colaboradores, ambiente e comunidade e económica) maior a satisfação com o trabalho e se as condições de trabalho na organização apresentarem níveis elevados, maior a Satisfação no Trabalho. Dos resultados obtidos, concluiu-se uma associação positiva entre as três dimensões da Responsabilidade Social com a Satisfação no Trabalho, em particular uma associação mais elevada com a dimensão Percepção da Responsabilidade Social - Ambiente e Comunidade. Destaca-se também que a Satisfação no Trabalho está mais associada com a percepção do reconhecimento profissional do que com as condições de trabalho no call center.
