Another Paradox In Naive Set-Theory

Reasonning in naive set theory (with unlimited comprehension), we derive a paradox (a formal contradiction) which can be seen as a variant of the Burali-Forti paradox. Presented by Robert Goldblatt     

Organisational Justice and Citizenship Behaviors: A Study in the Portuguese Cultural Context

Theoretical and empirical evidence suggests that justice and organisational citizenship behaviors (OCB), as well as the relationship between them, are not culture free. However, most studies have been carried out in parts of Asia and Northern Europe, and especially in the USA, shedding little understanding on the dynamics of justice and OCB in less‐studied contexts. We show how four dimensions of organisational justice predict four dimensions of OCB in an under‐studied context—Portugal, a feminine, collectivistic, high power distance and low performance‐oriented culture—a profile that is antipodal to that of US culture. A sample of 269 employees reported their justice perceptions, their OCBs being described by supervisors. The findings suggest that: (a) employees are more sensitive to the interactional dimensions of justice than to the procedural and distributive ones; (b) among the interactional dimensions, the interpersonal one is more predictive of some OCB dimensions than the informational one. Des données théoriques et empiriques suggèrent que la justice et les comportements de citoyenneté organisationnelle (OCB), tout comme la relation entre eux, ne sont pas sans base culturelle. Toutefois, la plupart des études ont été menées dans certaines parties de l’Asie, de l’Europe du Nord, et plus particulièrement aux USA, ce qui restreint la compréhension des dynamiques de la justice et des OCB qui peuvent être appréhendés dans d’autres contextes. Nous montrons comment 4 dimensions de la justice organisationnelle prédisent 4 dimensions des OCB dans un contexte peu étudié—le Portugal, une culture féminine, orientée vers la collectivité, avec une forte distance au pouvoir et de faibles performances—, un profil aux antipodes de la culture américaine. Chacun des 269 employés de l’échantillon indique ses perceptions de la justice, ses OCB ont été décrits par ses supérieurs. Les résultats montrent que (a) les employés sont plus sensibles aux dimensions interactionnelles de la justice qu’à celles procédurales et distributives (b) parmi les dimensions interactionnelles, l’interpersonnelle est plus prédictive de certaines dimensions des OCB plutôt que l’informationnelle.     

Situational consistency in behavioral patterns of aggressive boys: Methodological considerations on observational measures

The issue of situational consistency is of great interest for early intervention with aggressive boys, but efforts to show behavior stability across settings have been unsuccessful to date, due principally to methodological problems. It is argued here that a more appropriate matching of response form, interaction partner, and situations should increase the situation consistency of observed behavior. The results support this proposition in that, more crosssetting behavior consistency was found in the pairing of situations where aggressive boys (age 6–7 years) were interacting with an adult female (mother/child versus baby-sitter/child) than in the pairing of situations where the boys were interacting with an adult male (mother/child versus father/child) or with the teacher in a nondyadic situation (classroom). The implications of using an extreme group are also discussed.This research program was funded by Le Conseil Québécois de la Recherche Sociale, the Quebec Government's FCAR research program, the Social Sciences and Humanities Research Council of Canada, the Canadian Ministry of Employment and Immigration, and the University of Montreal FDR program.

DEGRÉ DE CONTACT ET STRESS ACCULTURATIF DANS LE PROCESSUS D'ADAPTATION DES RÉFUGIÉS AFRICAINS

This study examines some aspects of the adaptive process of African refugees taking up residence in Quebec city, a rather culturally homogenous area. Considering that acculturative stress and degree of contact and participation with the host society are strong indicators of one's adjustment to a new culture, the main hypothesis is that the more contact and participation one establishes with the host society, the less acculturative stress he will report. Out of 62 subjects who voluntarily accepted to participate in the study, 57 were retained for analysis. Results reveal no significant relationship between stress and contact. Multiple regression analyses used to determine the significant predictor variables indicate that age and length of stay explain 19.5% of the total variance for stress while length of stay, sex and adaptive options explain 44% of the total variance for contact. These results tend to demonstrate that, for African refugees, degree of contact is a better indicator of adaptation than stress.     

ROLE DU PARTENAIRE ADULTE DANS LA GENESE DE LA COMMUNICATION: LES PRINCIPAUX COURANTS THEORIQUES

According to some authors, socialisation explains the emergence and development of communicative behavior. Other authors think that this development is an autonomous process: either because communication and even sociability exist per se and are innate activities of the infant, or because the development of communication is an aspect of cognitive development. Up to the present time the experiments and observations do not lend support to one hypothesis over the other: there are strong arguments in both directions, without them being definitive. Two approaches seem suited to establish the range and restriction of these different theoretical points of view: a systematic analysis of the reciprocal roles of the adult and the infant during interaction and the study of the influence of certain characteristics of the family or institutional milieu on the communicative behavior of the infant.     

How Bad Is Rape?

I argue that to be compelled to do routine work is to be gravely harmed. Indeed, that pink-collar work is a more serious harm to women than rape. My purpose is to urge politically active feminists and feminist organizations to arrange their priorities accordingly and devote most of their resources to working for the elimination of sex segregation in employment.     

L'APPRENTISSAGE DE LA NOTION D'INCLUSION DE CLASSES CHEZ DE JEUNES ENFANTS BAOULÉS (CÔTE D'IVOIRE)*

This training study of the concept of class inclusion follows a previous paper on the training of the conservation of liquids (Dasen et al. 1979). Twenty-eight African (Baoulé) children, aged 7 to 9 years, were attributed to two groups, matched on age, schooling and performance on a pretest comprising 5 concrete operational tasks. Fourteen subjects who performed at stages 1 or 2 on class inclusion were trained according to a method adapted from Inhelder et al. (1974). The training effect was measured during two post-tests at the interval of one month. The results show a stable training effect in half of the subjects; there is a statistically significant generalization to other concepts of the same stage. This finding, which is similar to what has been reported for European children, supports the hypothesis of connections between operational concepts based on the common structure of the ‘grouping’. A ‘time lag’ of about 2 years in the development of class inclusion appears when comparing Baoulé and European children. The absence of very rapid learning (‘actualization’) shows that this lag probably occurs at the competence and not only at the performance level. The training effect is sufficient to reduce and even bridge this lag.
