Rural youth in economically troubled regions develop plans for their future in a context in which opportunities for educational and occupational success generally lie elsewhere, prompting the need to migrate. This study investigates the links between rural adolescents' residential preferences and their plans for the future, perceptions of local opportunity, and ties to family and community. We examine whether residential preferences shape the pathways to adulthood through decisions about where to live as well as educational and occupational attainments. Residential preferences are indeed related to adolescents' academic achievements and future educational plans, their relationships with parents, and perceptions of local job opportunities, but they are not associated with family socioeconomic background and social ties to the community. For the most part, residential preferences are linked to where young people live and pursue higher education in the years after high school, but generally not to their socioeconomic attainment.  相似文献

Previous studies of abuse in male same-sex relationships have been limited by convenience samples and/or by incomplete assessments of partner abuse. We examined patterns of same-sex partner abuse in a random sample of 284 gay and bisexual men. Respondents reported on perpetration and receipt of physical, psychological, and sexual abuse over multiple time frames, as well as injuries resulting from abuse. Almost all respondents reported psychological abuse, more than one-third reported physical abuse, and 10% reported having engaged in unwanted sexual activity because of partner force or threats of force. More than half of recipients of partner violence reported sustaining injury. We found strong associations between different forms of abuse, and between severity of abuse receipt and perpetration.  相似文献

Young adults' romantic relationships are often unstable, commonly including breakup –reconcile patterns. From the developmental perspective of emerging adulthood exploration, such relationship “churning” is expected; however, minor conflicts are more common in churning relationships. Using data from the Toledo Adolescent Relationships Study (N = 792), the authors tested whether relationship churning is associated with more serious conflict, such as physical violence and verbal abuse. Couples who were stably broken up (breakup only—no reconciliation) were similar to those who were stably together in their conflict experiences. In contrast, churners (i.e., those involved in on/off relationships) were twice as likely as those who were stably together or stably broken up to report physical violence and half again as likely to report the presence of verbal abuse in their relationships; this association between churning and conflict held net of a host of demographic, personal, and relationship characteristics. These findings have implications for our better understanding of unhealthy relationship behaviors.  相似文献

The original process model of evidence-based practice (EBP) is described, and contrasted with the empirically supported treatments (EST) initiative which designated selected interventions as meeting some evidentiary benchmark (e.g., supported by two-well-designed randomized controlled trials). EBP does not utilize lists of ESTs, and designating a given psychotherapy as empirically supported is actually antithetical to the EBP decision-making process. Much of the resistance to EBP within social work may be attributable to confusion between EBP as it was originally conceived as a mutual decision-making process occurring between the clinician and the client, and the promulgation of lists of EST and the subsequent urging that social workers select their psychotherapies from such lists. The latter is not scientifically justifiable, nor does it taken into account other variables crucial to EBP, such as professional values, clinical expertise, client preferences and values, and available resources. EBP as it was originally conceived has much to add to the practice of clinical social work.  相似文献

The primary purpose of this study was to examine the effect of the intensity of emotion expression on children's developing ability to label emotion during a dynamic presentation of five facial expressions (anger, disgust, fear, happiness, and sadness). A computerized task (AFFECT—animated full facial expression comprehension test) was used to display facial emotion expressions as animations with four levels of intensity (35, 50, 75, and 100 percent). In this study, which employed a cross-sectional design, 240 participants from 4 to 18 years completed the AFFECT. Results indicated that recognition ability developed for each of the emotions, with the exception of disgust, over the age range tested. Girls were more accurate than boys, especially for anger and disgust expressions. Recognition accuracy was found to increase as a function of the intensity of emotional expressions.  相似文献

This study investigated how men and women perceive online and offline sexual and emotional infidelity. Undergraduates from a large university in Northern Ireland participated in the study. It was found that men, when forced to decide, were more upset by sexual infidelity and women by emotional infidelity. It was also found that men were more likely to believe that women have sex when in love and that women believe that men have sex even when they are not in love. It was not, however, found that either men or women believed that having cybersex implied the other was also in love or that being in love online implied they were having cybersex. These results are explained through a social‐cognitive lens.  相似文献

Video games are an important form of media that have the potential to impact gender role attitudes. Sexist portrayals of characters may affect gender behaviors and attitudes. As such, it is important to discover how characters, particularly females, are portrayed in video games. The current study examined video game magazines analyzing the portrayal of female video game characters and how this portrayal has changed in the last twenty years. Results indicate a growing trend toward a decreased benevolent sexism portrayal and an increase in a hostile sexism portrayal over time.  相似文献

Combining statistical models is an useful approach in all the research area where a global picture of the problem needs to be constructed by binding together evidence from different sources [M.S. Massa and S.L. Lauritzen Combining Statistical Models, M. Viana and H. Wynn, eds., American Mathematical Society, Providence, RI, 2010, pp. 239–259]. In this paper, we investigate the effectiveness of combining a fixed number of Gaussian graphical models respecting some consistency assumptions in problems of model building. In particular, we use the meta-Markov combination of Gaussian graphical models as detailed in Massa and Lauritzen and compare model selection results obtained by combining selections over smaller sets of variables with selection results over all variables of interest. In order to do so, we carry out some simulation studies in which different criteria are considered for the selection procedures. We conclude that the combination performs, generally, better than global estimation, is computationally simpler by virtue of having fewer and simpler models to work on, and has an intuitive appeal to a wide variety of contexts.  相似文献

We display pseudo-likelihood as a special case of a general estimation technique based on proper scoring rules. Such a rule supplies an unbiased estimating equation for any statistical model, and this can be extended to allow for missing data. When the scoring rule has a simple local structure, as in many spatial models, the need to compute problematic normalising constants is avoided. We illustrate the approach through an analysis of data on disease in bell pepper plants.  相似文献

How infectious diseases spread in space and time is an important question that has received considerable theoretical attention. There are, however, few empirical studies to support theoretical approaches, because data is scarce. In this paper we propose to model the epidemic spread of measles in the London boroughs between 1960 and 1970 by an extension of the Kriged Kalman filter (Mardia et al. , 1998) to count data. Results show the flexibility of our approach in describing complex spatio-temporal dynamics.  相似文献
