This study examined the longitudinal associations among maternal warmth, adolescents' self‐disclosure, and maternal knowledge during the transition to adolescence. Three years of self‐report data were collected from 131 married mothers and their adolescents. Results from longitudinal analysis using adolescent reports indicated that greater maternal warmth in sixth grade predicted higher levels of adolescents' self‐disclosure in seventh grade, which in turn led to higher levels of maternal knowledge in eighth grade. Thus, adolescents' self‐disclosure served as an indirect link between higher maternal warmth and greater knowledge over time. An alternative model with prior self‐disclosure predicting subsequent maternal warmth and knowledge was not supported. Overall, this study demonstrated a time‐ordered process by which maternal warmth and adolescents' self‐disclosure predict maternal knowledge. Understanding such processes that affect parental knowledge may be beneficial for future prevention and intervention efforts during the transition to adolescence. 相似文献

In their professional capacities doctors are often confronted with clients who present with psycho-sexual problems. At the present time Australian medical students are provided with very little instruction in the areas of human sexual behaviour. This paper examines the attitudes and amount of information possessed by a cohort of second year medical students compared with groups of first and fifth year students; these attitudes and levels of information are then related to students' sex, religious affiliation, strength of religious conviction, where this is seen to be relevant. It is shown that some areas of ignorance exist. The paper concludes by outlining some aspects relevant to courses in human sexual behaviour. 相似文献

With increasing demand for low-density recreational services and limited supply of facilities to provide them, congestion is becoming an important management problem. The purpose of this paper is to outline a model of congestion, estimate the effect of it upon individual willingness to pay for wilderness experiences, and illustrate how these results might be used for efficient management. A survey of users of the Spanish Peaks Primitive Area indicates that their revealed willingness to pay is significantly affected by encroachments upon the solitude they experience during their trip. Consequently, congestion effects for such services can be measured and used in the formation of administrative policy. 相似文献

Objective: The authors sought to assess military veterans' functioning in college by comparing their experience with that of civilian students. Participants: The study, conducted from April 2012 to February 2013, included 445 civilian and 61 student service member/veteran (SSM/V) undergraduates, drawn from a community college and two 4-year Catholic colleges, in Pennsylvania, New Jersey, and New York. Methods: Participants completed anonymous online surveys. Six areas of functioning in transition to college were examined: Health, Fitting In, Emotional Adjustment, Productivity, Perceived Career Support, and Social Engagement. Results: Students, both SSM/V and civilian, with past exposure to a potentially traumatic event fit in worse than students without such exposure. Past exposure to trauma was associated with poorer emotional adjustment in civilian students, but not in SSM/V. Conclusions: Implications of results were discussed. 相似文献

In earlier work (Gelfand and Smith, 1990 and Gelfand et al, 1990) a sampling based approach using the Gibbs sampler was offered as a means for developing marginal posterior densities for a wide range of Bayesian problems several of which were previously inaccessible. Our purpose here is two-fold. First we flesh out the implementation of this approach for calculation of arbitrary expectations of interest. Secondly we offer comparison with perhaps the most prominent approach for calculating posterior expectations, analytic approximation involving application of the LaPlace method. Several illustrative examples are discussed as well. Clear advantages for the sampling based approach emerge. 相似文献

Individuals with autism spectrum disorders (ASDs) have complex needs requiring regular service utilization. Policymakers, administrators, and community leaders are looking for ways to finance ASD services and systems. Understanding the fiscal resources that support ASD services is essential. This article uses fiscal mapping to explore ASD funding streams in Ohio. Fiscal mapping steps are overviewed to assist ASD stakeholders in identifying and examining ASD-related funding. Implications are drawn related to how fiscal mapping could be used to identify and leverage funding for ASD services. The resulting information is critical to utilizing existing resources, advocating for resources, and leveraging available funds. 相似文献

Weblogs, or personal websites updated in time-based fashions, are common media used for expressing thoughts and networking
socially online (Lenhart et al. in Teens and social media, Pew Internet and American Life Project, Washington, DC, 2007). This qualitative study describes the content of 100 adolescent weblog users’ communications through a risk and resilience
framework. These users primarily utilized weblogs for community building, as most of their postings involved communications
designed to foster and nurture relationships with peers via the weblog. The majority of the content posted involved the discussion
of common prosocial behaviors, such as doing homework, hanging out with friends, or planning for events such as dances. A
surprisingly small amount of weblog content included text about risk factors and related problem behaviors. Findings are described
in relation to adolescent use of the Internet. Specific implications are drawn for social workers and other professionals
involved in youth work. 相似文献
