Do Personality Changes Occur in Parents Receiving Behavioral Family Therapy?

The present outcome study is a preliminary report on whether personality changes occur in parents receiving behavioral family therapy. Behavioral techniques for changing the identified patient's presenting problem were taught to the parents and each family member was given a weekly behavioral homework assignment intended to change the dysfunctional interactions assessed in the family.
An analysis of pre and post measures using Cattell's 16PF questionnaire showed a significant decrease in the parent's self-sufficiency index, indicating increased group dependence. The mean number of sessions was 12.6. The results of this study raise questions about the nature of the personality changes occurring in family therapy of this type. Family therapists, often-times assuming the role of the "expert" for the family, may be unwittingly fostering group dependence and losses in confidence for parents receiving such family guidance.     

外国领导是怎么炼成的

具有“个人魅力”的领导人往往能使人对其忠诚,但并不是每个社会都需要一个“个人魅力”型的领导人,在非洲和一些拉美国家,个人魅力甚至会起到负作用。在没有个人魅力的时候,只要你付出更多的努力,也能成为一名优秀的领导人。     

Modelling the travel time of transit vehicles in real‐time through a GTFS‐based road network using GPS vehicle locations

Predicting the arrival time of a transit vehicle involves not only knowledge of its current position and schedule adherence, but also traffic conditions along the remainder of the route. Road networks are dynamic and can quickly change from free‐flowing to highly congested, which impacts the arrival time of transit vehicles, particularly buses which often share the road with other vehicles, so reliable predictions need to account for real‐time and future traffic conditions. The first step in this process is to construct a framework with which road state (traffic conditions) can be estimated using real‐time transit vehicle position data. Our proposed framework implements a vehicle model using a particle filter to estimate road travel times, which are used in a second model to estimate real‐time traffic conditions. Although development and testing took place in Auckland, New Zealand, we generalised each component to make the framework compatible with other public transport systems around the world. We demonstrate the real‐time feasibility and performance of our approach in real‐time, where a combination of R and C++ was used to obtain the necessary performance results. Future work will use these estimated traffic conditions in combination with historical data to obtain reliable arrival time predictions of transit vehicles.     

Diagnostic sequence of cocaine use disorder in relation to other mental health conditions among college students

Abstract

Objective: Cocaine use is increasing. Comorbidities and diagnostic sequencing are needed among college students to inform treatment of cocaine use disorder (CUD). Method: Using electronic medical records from the psychiatric clinic at the student health care center of a large, public university from 2005 to 2015, patients diagnosed with CUD were identified. Their top mental health conditions were identified and assessed to see whether the first diagnosis of these conditions was made (1) before, (2) at the same time as, or (3) after the first diagnosis of CUD. Results: Among the 50 CUD patients, their most common mental health comorbidities were alcohol use disorder, anxiety, depression, and cannabis use disorder. Anxiety and depression were likely to be diagnosed before CUD; alcohol and cannabis use disorders were likely to be diagnosed concurrently with CUD. Conclusion: Diagnostic sequencing can be used to inform screening, workup, and treatment for patients with CUD.     

Induced inefficiency as a response to the union threat

Milkman and Mitchell (1995) extend Rosen’s (1969) threat-effect hypothesis to suggest that the threat of unionization can induce inefficient underutilization of labor by nonunion firms. If firms follow this strategy, the apparent paradox of competitive coexistence in the face of higher union wages reflects induced nonunion firm inefficiency rather than superior union firm efficiency. Furthermore, this strategy decreases demand for nonunion workers in a partially unionized industry. A generalized cost function analysis of data from sawmills in the Pacific Northwest yields evidence that nonunion firms use this strategy.     

Limits to social capital: comparing network assistance in two New Orleans neighborhoods devastated by Hurricane Katrina

Sociological research emphasizes that personal networks offer social resources in times of need and that this capacity varies by the social position of those involved. Yet rarely are sociologists able to make direct comparisons of such inequalities. This study overcomes this methodological challenge by examining network activation among residents of two unequal neighborhoods severely devastated by Hurricane Katrina. Results indicate that local network capacities of Lower Ninth Ward residents relative to those of the more affluent Lakeview neighborhood dissipated before, during, and after the disaster to erode the life chances of individual residents and the neighborhood they once constituted.     

Physical Activity,Exercise, and Sedentary Behavior in College Students

Abstract

Objective: This article examines students’ perceptions of individual and institutional responsibility for sexual health so that institutions can better provide for the needs of their students to increase academic success and healthy relationship outcomes. Participants: Students from 2- and 4-year colleges in 1 state (N = 78). Methods: From May through November 2010, the authors used go-along interviews to examine students’ perceptions of resources for sexual health on their campuses. Results: Participants believed that it is the college's responsibility to provide resources and the responsibility of students to access resources. Participants at 2-year schools wanted referrals to resources, whereas participants at 4-year schools expected resources to be available and emphasized the importance of a supportive community. Conclusions: Students at 2- and 4-year colleges have different expectations of their institutions; by making resources and referrals for sexual health available, colleges can better serve their students, which will result in improved health outcomes.
