We examined the relationship between personal and interpersonal indicators of postdivorce adjustment and dimensions of coparenting (support, overt conflict, covert conflict) using data from 176 recently divorced mothers. Mothers’ satisfaction with the divorce decree, perceptions of fathers as important for child development, and being satisfied with fathers’ parenting were associated with more supportive coparenting. Mothers’ satisfaction with the divorce decree and fathers’ parenting were associated with less overt conflict. Factors differed for mothers’ reports of their own and their former spouses’ use of covert conflict behaviors, with these factors linked to satisfaction with the divorce decree and perceived stress, respectively.  相似文献

This article investigates the dominant messages Internet memes communicate about religion. Internet memes about religion are defined as, ‘memes circulated on the Internet whose images and texts focus on a variety of religious themes and/or religious traditions’ (Bellar et al., 2013). By drawing on meme genres identified by Shifman (2012) and analyzing techniques used to frame ideas concerning religion in memes, this study identifies common genres found amongst religious Internet meme and core frames used to present messages and assumptions about religion online. This article further draws attention to the importance of studying religion in digital contexts, as it highlights trends, recognized by scholars toward ‘Lived Religion’ within digital culture (Campbell, 2012). Lived Religion argues that contemporary media and digital culture provide important resources for presenting popular beliefs about religion. This study also suggests that studying Internet memes about religion provides a useful lens for understanding popular conceptions about religion within mainstream culture.  相似文献

Research has demonstrated a link between alcohol use and multiple forms of risky sexual behavior, particularly among college-age individuals. Studies have also linked heavy alcohol use to other problems, such as impaired consciousness resulting from an alcohol-induced blackout, which may impact sexual decision making. However, research has rarely examined sexual risk taking (SRT) in relation to blackouts, nor has it examined this construct during the precollege transition (i.e., the interval of time between high school graduation and college matriculation). This study examined the intersection between alcohol-involved SRT, blackouts, and gender in a sample of precollege individuals with prior alcohol use (N = 229; 54% male, 63% White). Results indicated that, despite drinking less per occasion, women reporting recent blackouts were at increased risk for experiencing unwanted, unsafe, and regretted sexual behaviors compared to men with recent blackouts and their peers with no recent blackouts. Women with recent blackouts also reported differences in alcohol expectancies that may increase their risk for experiencing negative consequences while drinking, including higher social expectancies and lower negative expectancies of danger. Future directions for research and implications for precollege interventions are discussed.  相似文献

There has been a rapid increase in the development of technological innovations to reduce the escalation and impact of alcohol problems among adolescents and adults. Technology-based interventions offer the possibility of reaching individuals who otherwise might not seek treatment, (e.g., those in remote areas, those not perceiving a need for treatment, or others who might resist treatment). This article describes 4 case examples of technology-based interventions for risky drinking: (a) a freely available and interactive Web site that provides individualized feedback and information on risky drinking patterns; (b) a brief intervention for adolescents that provides individualized feedback to teens regarding their alcohol use; (c) a computer-delivered screening and brief intervention for alcohol use among pregnant women; and (d) a simulation program for training social workers in screening and brief intervention. These case examples highlight how technology could have a role in addressing the Alcohol Misuse Grand Challenge.  相似文献

A number of areas related to learning under supervision have not been fully investigated, particularly the possibility of incorporating the method of classification into shape analysis. In this regard, practical ideas conducive to the improvement of form classification are the focus of interest. Our proposal is to employ a hybrid classifier built on Euclidean Distance Matrix Analysis (EDMA) and Procrustes distance, rather than generalised Procrustes analysis (GPA). In empirical terms, it has been demonstrated that there is notable difference between the estimated form and the true form when EDMA is used as the basis for computation. However, this does not seem to be the case when GPA is employed. With the assumption that no association exists between landmarks, EDMA and GPA are used to calculate the mean form and diagonal weighting matrix to build superimposing classifiers. As our findings indicate, with the use of EDMA estimators, the superimposing classifiers we propose work extremely well, as opposed to the use of GPA, as far as both simulated and real datasets are concerned.  相似文献

Demographers often form estimates by combining information from two data sources—a challenging problem when one or both data sources are incomplete. A classic example entails the construction of death probabilities, which requires death counts for the subpopulations under study and corresponding base population estimates. Approaches typically entail ‘back projection', as in Wrigley and Schofield's seminal analysis of historical English data, or ‘inverse’ or ‘forward projection’ as used by Lee in his important reanalysis of that work, both published in the 1980s. Our paper shows how forward and backward approaches can be optimally combined, using a generalized method of moments (GMM) framework. We apply the method to the estimation of death probabilities for relatively small subpopulations within the United States (men born 1930–39 by state of birth by birth cohort by race), combining data from vital statistics records and census samples.  相似文献

In this article we propose a novel framework for the modelling of non-stationary multivariate lattice processes. Our approach extends the locally stationary wavelet paradigm into the multivariate two-dimensional setting. As such the framework we develop permits the estimation of a spatially localised spectrum within a channel of interest and, more importantly, a localised cross-covariance which describes the localised coherence between channels. Associated estimation theory is also established which demonstrates that this multivariate spatial framework is properly defined and has suitable convergence properties. We also demonstrate how this model-based approach can be successfully used to classify a range of colour textures provided by an industrial collaborator, yielding superior results when compared against current state-of-the-art statistical image processing methods.  相似文献

There is a paradox in research on African Americans and non-Hispanic whites in the utilization of clergy. Research finds that African Americans have higher levels of religious service attendance and higher levels of contact with clergy. Research also finds that despite this, African Americans are less likely than non-Hispanic whites to seek out assistance from clergy for psychiatric disorders including depression and anxiety. The goal of this paper was to investigate race differences in the use of clergy for counseling for serious personal problems. It uses the National Survey of American Life. We find that non-Hispanic whites were more likely than African Americans to use clergy for a serious personal problem. The significant difference between African Americans and non-Hispanic whites appeared to be mediated by the fact that African Americans were more likely to have seen clergy in a religious setting and non-Hispanic whites were more likely to have seen clergy in other settings including hospitals.  相似文献
