A social identity theory of leadership

A social identity theory of leadership is described that views leadership as a group process generated by social categorization and prototype-based depersonalization processes associated with social identity. Group identification, as self-categorization, constructs an intragroup prototypicality gradient that invests the most prototypical member with the appearance of having influence; the appearance arises because members cognitively and behaviorally conform to the prototype. The appearance of influence becomes a reality through depersonalized social attraction processes that make followers agree and comply with the leader's ideas and suggestions. Consensual social attraction also imbues the leader with apparent status and creates a status-based structural differentiation within the group into leader(s) and followers, which has characteristics of unequal status intergroup relations. In addition, a fundamental attribution process constructs a charismatic leadership personality for the leader, which further empowers the leader and sharpens the leader-follower status differential. Empirical support for the theory is reviewed and a range of implications discussed, including intergroup dimensions, uncertainty reduction and extremism, power, and pitfalls of prototype-based leadership.

Communication and health beliefs - Mass and interpersonal influences on perceptions of risk to self and others

This study investigated the impact of media coverage of a health issue (skin cancer) on judgements of risk to self and others and the role of related communication processes. Consistent with predictions derived from the impersonal impact hypothesis, the effects of mass communication were more evident in perceptions of risk to others rather than in perceptions of personal risk. Perceptions of personal risk were more strongly correlated with interpersonal communication. However, as suggested by media system dependency theory, the relationship between mass communication and beliefs was complex. The impact of mass communication on both personal and impersonal perceptions was bound to be moderated by self-reported dependence on mass mediated information. The effect of this two-way interaction 071 perceptions of personal risk was partially mediated through interpersonal communication. Results point to the interdependence of mass and interpersonal communication as sources of social influence and the role of media dependency in shaping media impact.

Nucleation, growth and breakage phenomena in agitated wet granulation processes: a review

Wet agglomeration processes have traditionally been considered an empirical art, with great difficulties in predicting and explaining observed behaviour. Industry has faced a range of problems including large recycle ratios, poor product quality control, surging and even the total failure of scale up from laboratory to full scale production. However, in recent years there has been a rapid advancement in our understanding of the fundamental processes that control granulation behaviour and product properties. This review critically evaluates the current understanding of the three key areas of wet granulation processes: wetting and nucleation, consolidation and growth, and breakage and attrition. Particular emphasis is placed on the fact that there now exist theoretical models which predict or explain the majority of experimentally observed behaviour. Provided that the correct material properties and operating parameters are known, it is now possible to make useful predictions about how a material will granulate. The challenge that now faces us is to transfer these theoretical developments into industrial practice. Standard, reliable methods need to be developed to measure the formulation properties that control granulation behaviour, such as contact angle and dynamic yield strength. There also needs to be a better understanding of the flow patterns, mixing behaviour and impact velocities in different types of granulation equipment. (C) 2001 Elsevier Science B.V.

Putting the group back into unions: A social psychological contribution to understanding union support

Industrial relations research that attempts to grapple with individuals' union-related sentiments and activities often draws on one of two traditions of psychological research—the individual-level factors tradition (for example, personality and attitude-behaviour relations) and the social context tradition (for example, frustration-aggression and relative deprivation). This paper provides an overview of research conducted from within these traditions to explain union-related phenomena and identifies some of the limitations that arise as a consequence of a shared tendency to treat people in an atomistic fashion. The paper argues for an understanding of the psychological processes that underpin group-based action. To this end, it elaborates a theoretical framework based on social identity theory and self-categorisation theory that would allow us to examine the dynamic interplay between the individual, their cognitions and their environment. The paper concludes with a brief discussion of a specific case of union mobilisation, to indicate how this theoretical framework might aid empirical analysis.

As políticas de proteção social no contexto escolar

Esta dissertação teve o objetivo de investigar como a formalização das políticas de proteção social via programas e projetos socioeducativos se articulam com a educação escolarizada. Realiza uma discussão conceitual acerca das políticas de proteção social e “vulnerabilidade e risco social” a partir de aspectos históricos situando-as na lógica societária das desigualdades e complexificações das refrações da questão social do modelo capitalista de produção e reprodução social, sobretudo no contexto das reformas do Estado brasileiro enquanto demanda dos ajustes neoliberais. O lócus da pesquisa foi uma escola da rede pública municipal de Serra/ES. As investigações foram realizadas em duas etapas. A primeira constituiu-se de um estudo exploratório de caráter qualitativo. Por meio das análises abstraídas dessa fase, foi realizado um estudo de caso como segunda etapa da pesquisa. Os instrumentos utilizados, análise de documentos, observação participante e entrevistas, evidenciam que os programas e projetos socioeducativos desenvolvidos no espaço escolar visando a uma suposta proteção social, não guardam relação concreta com a melhoria dos processos de aprendizagem dos alunos, logo, seus efeitos na vida escolar desses alunos não foram evidenciados. Verificou-se ainda profunda desarticulação entre as propostas pedagógicas da escola e dos docentes com os programas e projetos investigados. A partir dos dados da pesquisa, pudemos ainda constatar que tais programas e projetos adentram o espaço escolar por meio de demandas externas envolvendo a Secretaria Municipal de Educação e a iniciativa privada. Concluímos que a proteção social no espaço escolar via programas e projetos socioeducativos necessita voltar-se à articulação com políticas públicas que ultrapassem os muros da escola e que de fato garantam o acesso a bens materiais e simbólicos com vista à melhoria das condições de vida material e sociocultural dos alunos a quem são destinados e, consequentemente, a melhoria da qualidade da educação escolarizada.

The decentralized social networking systems towards mobilizing actions of citizenship and solidarity against cancer

The goal of the present study is mapping the nature of possible contributions of participatory online platforms in citizen actions that may contribute in the fight against cancer and its associated consequences. These platforms are usually associated with entertainment: in that sense, we intent to test their validity in other domains such as health, as well as contribute to an expanded perception of their potential by their users. The research is based on the analysis of online solidarity networks, namely the ones residing on Facebook, Orkut and the blogosphere, that citizens have been gradually resorting to. The research is also based on the development of newer and more efficient solutions that provide the individual (directly or indirectly affected by issues of oncology) with the means to overcome feelings of impotence and fatality. In this article, we aim at summarizing the processes of usage of these decentralized, freer participatory platforms by citizens and institutions, while attempting to unravel existing hype and stigma; we also provide a first survey of the importance and the role of institutions in this kind of endeavor; lastly, we present a prototype, developed in the context of the present study, that is specifically dedicated to addressing oncology through social media. This prototype is already available online at www.talkingaboutcancer.org, however, still under development and testing. The main objective of this platform is to allow every citizen to freely build their network of contacts and information, according to their own individual and/ or collective needs and desires.

Accountability and co-production of information and control: social observatories and their relationship with government agencies

Abstract:Through the development of a proposal to categorize accountability into four stages - classical, cross-sectional, systemic, and diffused -, this article aims to identify characteristics of co-production of information and socio-political control of public administration in the work of Brazilian social observatories in relationship with government control agencies. The study analyses data from 20 social observatories and, particularly, three experiences of co-production of information and control, based on a systemic perspective on accountability and a model with four categories: Political and cultural; valuing; systemic-organizational, and production. The conclusions summarize characteristics of these practices, specific phases in the accountability processes, as well as the potentialities and challenges of co-production of information and control, which not only influences, but it is also influenced by the accountability system.

Teatro e igualdade de género : uma intervenção social e artística : relatório de estágio

O presente Relatório de Estágio tem como objecto de pesquisa a concepção e monitorização de duas Oficinas de Teatro dirigidas a dois grupos de mulheres constituídos, respectivamente, por estudantes universitárias e desempregadas. O estágio realizou-se entre Novembro/2013 e Junho/2014 na Quarta Parede - Associação de Artes Performativas da Covilhã e inseriu-se nos Empowerment Labs, laboratórios formativos que cruzam artes performativas e ciências sociais na reflexão e intervenção sobre a igualdade de género com foco no desemprego feminino. Este relatório expõe os três momentos do processo do estágio: pesquisa de referenciais teórico-práticos, concepção e monitorização das Oficinas de Teatro e reflexão a partir da prática laboratorial. Na pesquisa de referenciais, essencial para delinear a metodologia operacional e o programa de conteúdos, explorei dimensões como o feminismo e a igualdade de género, e procurei compreender de que forma o empowerment, a pedagogia de Paulo Freire e as metodologias do teatro aplicado serviam os objectivos do meu trabalho. A realização das oficinas foi o momento de experimentar as metodologias e o programa delineado. Tendo a igualdade de género como temática unificadora, o empowerment através da arte como objectivo maior e o teatro aplicado como base metodológica, as oficinas inserem-se nos processos de educação não-formal aplicados ao incremento de recursos intelectuais, emocionais, sociais, expressivos e criativos e, neste caso específico, à ampliação da consciência de género. Neste sentido, as oficinas desenvolveram uma abordagem metodológica processual, participativa e multidisciplinar, orientada para a pesquisa performativa, primeiro de uma dramaturgia individual, depois de uma dramaturgia do colectivo e, por fim, de uma dramaturgia orientada para a igualdade de género. O conceito de “dramaturgia” surge aqui no sentido metodológico do pachwork (trabalho com retalhos) e do sampling (recolha e transformação de materiais), relevante sobretudo na última fase, dedicada à construção colectiva de um exercício performativo apresentado publicamente.
