The Spacing of Births Among French-Canadian Families: An Historical Approach*

Utilisant la généalogie d'une seule famille-souche canadienne-française de 1650 à 1950, l'auteur compare l'intervalle entre les naissances dans la branehe canadienne et dans la branche américaine de cette famille. Indépendamment de la taille des families, l'intervalle s'accroit au cours des ans du côté américain. Une croissance de l'espacement ne se produit pas, par ailleurs, du côté canadien. II appert done que l'espacement progressif des naissances ne se produit que parmi les couples américains et que le comportement de ceux-ci diffère de celui des couples canadiens. La présente recherche a pour but secondaire de mettre en lumière l'utilité des généalogies en démographie, particulièrement dans l'étude de la fécondité. La comparaison des résultats obtenus ici avec ceux qui proviennent d'autres études de l'espacement des naissances illustre l'usage que Ton peut f aire de telles données historiques: on a utilisé en l'occurrence les régistres ayant trait à une seule famille pendant trois siècles. Cette famille n'est pas nécessaire-ment représentative de la famille canadienne-francaise. II s'agit plutôt de l'étude démographique d'un cas familial dans le temps et dans l'espace.     

Cultural safety and the duty of care

Rural youth, especially those of indigenous and immigrant cultures caught up in rural-urban migration, are vulnerable when the duty of care mandate transfers from families to state child welfare agents. The notion of cultural safety is examined in relation to the duty of care mandate assigned to child welfare workers when the state intervenes in family life.     

Psychosocial Factors Related to Gambling Abstinence and Relapse in Members of Gamblers Anonymous

Problem gamblers account for almost one-third of the industry’s total revenue with the adverse effects of problem gambling including significant financial loss, legal and occupational difficulties, family problems, psychological distress and suicide. As such, it is important to understand the influential factors in gambling abstinence and relapse, which will assist in the development of relapse prevention methods in therapeutic treatment regimes. This paper reported the role of a set of seven predictors in distinguishing between abstinent and relapsed gamblers among 75 Gambling Anonymous (GA) members (55 males; 20 females; Mean age 45 years) in Southeast Queensland. The measures taken were meeting Attendance and Participation, Social Support, God Belief, Belief in a Higher Power, Working the 12-steps of Recovery, Gambling Urges and Erroneous Cognitions. Discriminant analysis revealed that the variables separating the two groups were significant, suggesting that GA members achieving abstinence could be distinguished from those who relapsed, with Attendance and Participation, and Social Support contributing the greatest influence on member’s ability to abstain from gambling. The findings suggested that GA member’s involvement in meetings, and support from family and friends had significant impact on their gambling abstinence. In contrast, increased gambling urges and erroneous cognitions increased the chance of relapse.     

Unexpected Pathways Through Education: Why Do Some Students Not Succeed in School and What Helps Others Beat the Odds?

In this overview of Volume 64, Issue 1, of the Journal of Social Issues , we describe why it is important to consider the diversity of student pathways through time and in context and why it is important to focus particularly on youth who defy predictions. We describe the ways in which expectations are formed in statistical analysis and also in real-world education systems and how the structural rigidity inherent in such systems can lead to poor person–environment fit for young people in education or training and to misleading statistical analysis. Our intention is to move beyond analytic approaches that assume "one size fits all" while recognizing both that policy cannot provide fully individualized environments for everyone and that research cannot focus only on the unique characteristics of each individual. By focusing on individuals for whom our models typically do not apply, we highlight the value of research on complex but meaningful patterns of commonality among people, not in terms of the average person or effects, but in terms of coherent, distinct, and relatively homogenous subgroups of people experiencing systematic and consequential differences in their lives and lifepaths .     

Horizontal and vertical island biogeography of arthropods on green roofs: a review

From an ecological perspective, urban green roofs can be viewed as green islands embedded in an urban matrix. Island biogeography theory suggests that species richness on an island is the outcome of dynamic equilibrium between immigration and extinction. Immigration is affected by the size of an island and distance of an island from a colonizing source. In the context of green roofs, building height and horizontal distance from green areas can potentially be a limiting factor for many species. Here, we considered two distance components of green roofs - vertical (building height) and horizontal (distance of building from open green areas). Based on island biogeography theory, we would expect species richness or community similarity to be negatively related to horizontal or vertical distances from colonizing sources. The green roof literature addressing such questions is currently sparse. In our review comprised of 10 studies, we were unable to identify consistent statistically significant richness-distance or community similarity-distance (vertical or horizontal) relationships. The absence of statistically significant relationships could be due in large part to low statistical power as a consequence of both the paucity of roofs and limited range of vertical distances in many of the existing studies. In addition, these roofs differ in numerous aspects (e.g. roof size, age, substrate type, plant composition and building height). The low number of replicates, combined with the lack of homogeneity among replicates combines to reduce statistical power and our ability to detect differences.     

Leadership and stress: A meta-analytic review

Stress has been implicated as an important determinant of leadership functioning. Conversely, the behavior of leaders has long been argued to be a major factor in determining the stress levels of followers. Yet despite the widespread acknowledgement that stress and leadership are linked, there has been no systematic attempt to organize and summarize these literatures. In the present, we meta-analytically review the relationship between three leadership constructs (transformational leadership, leader-member exchange, and abusive supervision) and stress and burnout. Our analyses confirm that leader stress influences leader behavior and that leadership behaviors and leader-follower relationships are significant determinants of stress and burnout in subordinates. We build on these results to suggest new avenues for research in this domain as well as discussing how these results can inform practice with regards to leader development.
