How the Perceptions of Five Dimensions of Corporate Citizenship and Their Inter-Inconsistencies Predict Affective Commitment

Abstract: Through a convenience sample of 260 employees, the study shows how employees’ perceptions about corporate citizenship (CC) predict their affective commitment. The study was carried out in Portugal, a high in-group and low societal collectivistic culture. Maignan et al.’s (1999, Journal of the Academy of Marketing Science27(4), 455–469) construct, including economic, legal, ethical, and discretionary responsibilities was used. The main findings are: (a) contrary to what has been presumed in the literature, the discretionary dimension includes two factors: CC toward employees and toward community; (b) perceptions of CC explain 35% of unique variance of affective commitment; (c) the best predictors are perceptions of economic and legal CC and, mainly, perceptions of discretionary CC toward employees; (d) the perceptions of discretionary CC toward employees are significantly better predictors of affective commitment than are perceptions of economic, ethical, and discretionary CC toward the community; (e) perceived inconsistency of the several CC dimensions is detrimental to employees’ affective commitment. The study questions the four-dimensional model of the CC construct as operationalized by Maignan et al., suggests that culture should be included as a moderating variable in future research, and stresses that affective commitment may decrease when employees perceive that their organizations act upon the several areas of CC inconsistently.

Worldwide (poly)phenol intake: assessment methods and identified gaps.

Abstract: (Poly)phenols (PPs) are plant secondary metabolites widely distributed in dietary sources, and several evidences show that consumption of PP has a positive impact in human health. However, the correct estimation of food intake and the estimation of PP content of foods are essential to associate PPs intake with health effects. This review aimed to gather information from several studies on PP intake in different countries, compare methods used for both assessment of food intake and PP quantification and highlight existing gaps and future directions. Twenty-four studies of PP intake from thirteen countries were selected for analysis. The selected studies included assessment of all plant food groups contributing to PP intake, total PP content and/or content of major classes (flavonoids or phenolic acids), a large study population and both genders. Most studies presented daily intakes of extractable (poly)phenols. Very few studies have determined intake of non-extractable (poly)phenols, which is a very important fraction of PPs contributing to total PP intake. High heterogeneity was observed among countries regarding the intake of total PP intake and the two main PP classes. This may reflect not only different diet patterns, but also different methods used for collecting food consumption data and estimation of PP content. Thus, criteria of harmonization are suggested regarding assessment of food intake, determination of PP content in foods and validation with biomarkers.

Violência escolar: Metodologias de identificação dos alunos agressores e/ou vítimas

Abstract: O presente trabalho tem como principal objectivo estabelecer uma comparacao entre diferentes metodologias utilizadas na caracterizacao dos alunos que se envolvem em situacoes de violencia escolar, particularmente em comportamentos de bullying . Enquanto que a utilizacao de instrumentos que remetem para uma auto-resposta colocam em evidencia limitacoes relativas a autenticidade e objectividade das respostas, a utilizacao de instrumentos de resposta pelos pares aumenta a fidelidade estatistica dos resultados mas realca outro tipo de constrangimentos relacionados com a ausencia de conhecimento de algumas vivencias internas dos outros. Deste modo, parecem as metodologias de auto-resposta mais adequadas para identificar os alunos vitimizados, enquanto as metodologias de hetero-resposta parecem mais adequadas para identificar os alunos agressores. Utilizando dois instrumentos numa amostra de 680 alunos do 3.o ciclo (com idades compreendidas entre os 12 e os 17 anos) da area da Grande Lisboa, os resultados obtidos sugerem que diferentes percepcoes do fenomeno conduzem a diferentes niveis de incidencia e estatutos de envolvimento no âmbito da violencia escolar. Nomeadamente, verificou-se uma maior visibilidade de comportamentos violentos atribuidos ao genero masculino nas hetero-respostas, e um numero superior de vitimas e de vitimas-agressivas nas auto-respostas.

Rethinking the Employees Perceptions of Corporate Citizenship Dimensionalization.

Abstract: The article suggests that the four-factor model of corporate citizenship (CC: economic, legal, ethical, and discretionary responsibilities) does not fairly represent all pertinent dimensions of employees’ CC perceptions. Based on an empirical study with a sample of 316 employees, we show that, at least in some contexts, individuals distinguish seven CC dimensions: (1) economic responsibilities toward customers; (2) economic responsibilities toward owners; (3) legal responsibilities; (4) ethical responsibilities; (5) discretionary responsibilities toward employees; (6) discretionary responsibilities toward the community; and (7) discretionary responsibilities toward the natural environment. We do not suggest that this seven-factor model represents all of the (more) relevant CC dimensions in the employees’ minds. We aim to share evidence showing that the four-factor model proposed by Maignan et al. (Journal of the Academy of Marketing Science 27(4):455–469, 1999) may be refined, at least when the employees are the stakeholders in question.

Violência na escola: das políticas aos quotidianos

Abstract: Resumo A existencia de um alargado conjunto de situacoes, que designamos globalmente por violencia na escola, tem dado origem, nos anos mais recentes, a diversos debates publicos e a numerosas referencias nos meios de comunicacao social. Foi neste contexto que se desenhou no CIES uma linha de investigacao que questionou, dum ponto de vista sociologico, as concepcoes presentes no debate, procurando um confronto permanente entre a investigacao teorica e empirica, dando particular atencao a analise e exploracao das diferentes dimensoes que o fenomeno assume.
