Group Leaders as Gatekeepers: Testing Safety Climate Variations across Levels of Analysis

This paper tests the moderating effect of transformational supervisory leadership on the relationship between organisational and group climates, using safety climate in risky operations as an exemplar. Results indicated that under low or poor organisational climate, indicative of limited organisational commitment to employee safety, transformational leaders promoted a higher group climate as compared to the organisational climate. Similarly, under a weak organisational climate, indicative of limited consensus among company employees regarding the priority of safety, transformational leaders promoted a stronger group climate, reflecting greater consensus among group members. This pattern suggests that supervisory leaders can act as gatekeepers, with transformational leaders offering better protection against potentially harmful organisation‐level priorities. Furthermore, transformational supervisors better informed their members of the organisational priorities as they perceived them, resulting in a stronger relationship between individual supervisors' perceptions and members' organisational climate perceptions. Implications for climate and leadership research are discussed. On s'intéresse dans cet article à l'impact régulateur du leadership hiérarchique de transformation sur la relation entre les climats organisationnels et de groupe en utilisant comme exemple la sécurité dans les opérations à risque. Les résultats montrent qu'en cas de climat organisationnel médiocre signifiant une implication organisationnelle minimale à propos de la sécurité du personnel, les leaders de transformation favorisent l'émergence d'un climat de groupe plus satisfaisant que le climat organisationnel. De même, si le climat organisationnel est fragile, traduisant un accord approximatif des salariés sur la prioritéà accorder à la sécurité, les leaders de transformation sont à l'origine d'un climat de groupe renforcé, expression d'un meilleur consensus parmi les membres du groupe. Ce schéma laisse penser que les leaders hiérarchiques peuvent intervenir comme gardiens, les leaders de transformation offrant une meilleure protection contre les priorités organisationnelles potentiellement nocives. De plus, les managers de transformation informent mieux leur équipe des priorités organisationnelles telles qu'ils les perçoivent, ce qui provoque une relation plus étroite entre les perceptions personnelles du manager et celles que son groupe a du climat organisationnel. On réfléchit aux retombées de ce travail sur les recherches portant sur le climat et le leadership.     

Are There Differences in Fatalism Between Rural Southerners and Midwesterners?1

We conducted a phone survey of the rural South and Midwest examining fatalism and riskiness of health practices. Contrary to the contentions of some historians, ethnographers, writers, and social scientists, we found no evidence that Southerners were more fatalistic than Midwesterners. Southerners were not more likely to express the view that God or fate controlled their lives, and they were not more likely to take chances with their health and safety. The present findings contradict a commonly held view of the South, as well as a famous report in Science (Sims & Baumann, 1972) maintaining that higher death rates for tornadoes in this region might be due to Southern fatalism.     

Systematic Selection of Job Evaluation Items

Disposer d'items pertinents pouvant servir à la comparaison des postes est de premiere importance. Pourtant la littérature ne propose pas de solutions claires pour la selection de ces items. Notre travail suggere des principes pouvant presider a leur selection et a leur elaboration. Une serie d'items d'evaluation ont été selectionries et soumis a une prevalidation. L'analyse des relations entre les items d'evaluation des taches a mis en evidence trois types de relations: lineaires, non lineaires et absence de relations. Les items en relation lineaire et ceux qui pouvaient etre observes fidelement ont été juges convenir a revaluation du travail.
Des principes complementaires de selection des items ont été tires de l'analyse de contenu: les items decrivant la realisation de la tache, le niveau de la performance, et les items suffisamment generaux et independants de postes precis ou de groupes professionnels ont été retenus. Quatre dimensions de 1'evaluation du travail ont aussi été mises en evidence (la notion de limitation de l'autonomie dans la realisation de la tache les concerne tous): (1) precision des instructions recues, (2) controle hierarchique, (3) maitrise du travail, et (4) possibility d'introduire des changements.
Sur la base des principes et des dimensions, on a defini une serie de sept items generaux de 1'evaluation du travail. Les evaluations empiriques ont corrobore l'hypothese selon laquelle une hierarchie des postes approximative-ment unidimensionnelle pouvait etre obtenue.     

Grafting Modalities onto Substructural Implication Systems

We investigate the semantics of the logical systems obtained by introducing the modalities and into the family of substructural implication logics (including relevant, linear and intuitionistic implication). Then, in the spirit of the LDS (Labelled Deductive Systems) methodology, we "import" this semantics into the classical proof system KE. This leads to the formulation of a uniform labelled refutation system for the new logics which is a natural extension of a system for substructural implication developed by the first two authors in a previous paper.     

Launching themes in Israeli fathers and mothers

This study focused on launching processes as reflected in the reactions of Israeli parents to the drafting of their eldest son. A questionnaire tapping parents' reactions was constructed and administered to 237 couples. Factor analysis delineated eight substantive factors: Emotional Investment, Parent-Child Strains, Fostering Son's Maturity, Parental Disengagement, Parent's Transitional Phase, Dissatisfaction with Army, Son's Unpreparedness, and Strengthening Family Relations. The factors depicted modes of coping with launching and transitional midlife processes. The construct validity of the factor scales was examined in a multivariate regression analysis with 12 predictor variables related to sociodemographics, attitudes, personal concerns, and satisfactions. Mothers differed from fathers in some factor scale means as well as in the pattern in which the predictor variables related to the factor scale scores. The results are interpreted in terms of ambivalent launching reactions involving distress on the one hand and a sense of growth on the other. While adaptation to this transition in the family takes place within a specific cultural context, its implications for universal launching features are also discussed.     

Moses' “Revelation” on Mount Horeb as a near-death experience

Moses, the leader and lawgiver to the people of Israel, went through a metamorphosis during his stay in the Sinai Desert, which can be explained as a near-death or near-death-like experience. Moses saw and heard God in the burning bush and yet survived. Following his revelation, he reached a higher level of consciousness, which enabled personality changes to occur. From being a simple shepherd of his father-in-law's flock, he turned into a prophet and charismatic leader of his people.     

A Meta-model of Access Control in a Fibred Security Language

The issue of representing access control requirements continues to demand significant attention. The focus of researchers has traditionally been on developing particular access control models and policy specification languages for particular applications. However, this approach has resulted in an unnecessary surfeit of models and languages. In contrast, we describe a general access control model and a logic-based specification language from which both existing and novel access control models may be derived as particular cases and from which several approaches can be developed for domain-specific applications. We will argue that our general framework has a number of specific attractions and an implication of our work is to encourage a methodological shift from a study of the particulars of access control to its generalities.
