A family systems approach to conciliation in separation and divorce

This paper argues for a family systems approach to families who are in conflict during the process of divorce, particularly in relation to custody and access for their children. The concept of 'conciliation' as a brief method of intervention is both defined and discussed and principles and skills are identified. The influence of the context within which conciliation is practised and in particular, the power which the conciliator holds, or is perceived by the family to hold, is also discussed. These ideas are illustrated by case examples.     

可卡因对6-羟基多巴胺所致大脑单侧黑质纹状体系统损伤的大白鼠的旋转行为的影响

本实验观察了Holtzman种系雌性大白鼠34只。以6-OHDA制备单侧大脑黑质纹状体系统损伤的旋转行为模式。在特殊的和自动的球形旋转仪中共进行3次行为观察。以伤侧多巴胺的耗竭率在85％以上,以及具有优势地同侧性的旋转行为的实验动物的实验数据作为分析和讨论的依据。34只雌性大白鼠均符合上述条件。本实验所观察到的盐酸可卡因对动物的旋转行为的影响,其主要结果如下: 可卡因可使实验动物引起刻板的同侧性的旋转行为,其作用迅速。不同剂量的可卡因对动物的旋转行为有不同的影响。 单冷注射可卡因对动物的旋转行为能明显地引起长的至少持续一个星期的促进作用。这就提示,对脑和行为具有持久作用的心理运动的兴奋药,没有必要反复给药。     

On more powerful tests of judge agreement with a known standard

To establish the existence of his abilities, a judge is given the task of classifying each ofN=rs subjects into one ofr known categories, each containings of the subjects. An incomplete design is proposed whereby the judge is presented withb groups, each one containingn=rs/b<r subjects. Then different categories corresponding to members of the group are known. Using the total number of correct classifications, this method of grouping is compared to that in which the group size is equal to the number of categories. The incomplete grouping is shown to yield a more powerful test for discriminating between the null hypothesis that the judge is guessing the classifications and the alternative hypothesis that he has some definite abilities. The incomplete design is found to be most effective (powerful) when the number of subjects in a group is limited to two or three.The author is grateful for the suggestions of the referees and the editor, which greatly improved the paper.     

Habituation in the rat fetus.

Rat fetuses exhibit motor and cardiac responses to chemosensory stimulation on Days 20 and 21 of gestation. The first experiment demonstrated that fetuses exhibit an increase in overall motor activity and decrease in heartrate in response to an initial intraoral infusion of a lemon solution. After a series of nine exposures, however, fetuses no longer exhibit motor or cardiac responses to lemon infusion, suggesting the existence of a habituation-like process. Responsiveness recovers spontaneously following a 3- to 9-min period without stimulation. In a second experiment, a dishabituation treatment was administered to distinguish habituation, which is a centrally mediated decrement in response, from effector fatigue, sensory adaptation, and other peripheral mechanisms that can result in reduced responsiveness. A single infusion of mint following a series of nine lemon exposures was effective in reinstating fetal motor responses to lemon on both Days 20 and 21, but reinstated cardiac responses only on Day 21. Rat fetuses habituate to repeated chemosensory stimulation, suggesting the utility of the habituation paradigm in measuring CNS development during the perinatal period.     

The Impact of Religiosity on Substance Abuse and Obesity in African Americans

Among the African American community, there exist many health disparities which warrant greater examination through the practice of social work. The aim of the present research was to explore the impact of religiosity on substance abuse and obesity among African American populations by employing a systematic review of the current body of literature on this subject. While many of the studies reviewed found at least a weak relationship between religiosity and obesity, such results were not consistent across all materials examined. Among those studies that found a correlation between these factors, many demonstrated that religiosity had a positive impact on substance abuse and obesity. A discussion of the implications of these findings is submitted as a means of illuminating the significance of all research findings that were examined. Limitations such as more standardized criteria for inclusion of research material are identified and discussed. Implications for future research are presented to promote the advancement of future efforts in this area research.
