Self‐Perceived Competence in Mainland China: A Multiwave Longitudinal Examination of Internalizing Symptoms in Chinese Adolescents 下载免费PDF全文

The present 9‐wave, 2‐year study examined whether Cole's (1991) theory of self‐perceived competence could help explain vulnerability to depressive and anxiety symptoms in a sample of adolescents from mainland China. Participants included 624 adolescents (319 females and 305 males) from an urban school in Changsha (n = 308) and from a rural school in Liuyang (n = 316). Findings showed that self‐perceived academic competence was negatively associated with prospective depressive and anxiety symptoms. Meanwhile, adolescents with low levels of self‐perceived social competence were at heightened risk for depressive symptoms during times of increased stressors (supporting a vulnerability‐stress model). These findings advance past research by highlighting new developmental pathways for depressive and anxiety symptoms in Chinese adolescents. 相似文献

Increasing numbers of children are being raised by their grandparents because their own parents are unable or unwilling to care for them. A case is presented illustrating how an Eriksonian life-cycle perspective clarifies the developmental demands on adolescents in these situations and provides a theoretical framework for organizing therapeutic work with them. 相似文献

Abstract Although rural residents often expect resource extraction to lead to local prosperity, much of the recent research finds that resource extraction is associated with poverty. This paper tests these results by examining whether the findings may be due to methodological factors such as the tendency to focus on extreme cases, particular extracting sectors, and certain periods of time. By comparing two localities that have followed very different developmental trajectories—the state of Wisconsin and Hokkaido Prefecture in Japan—during the period from 1970 to 1990, this paper addresses these issues. The results do not clearly support either the expectation that resource extraction will lead to poverty or that it will lead to economic prosperity. Instead, like a handful of studies on resource dependency, the results indicate that the relationship between extraction and poverty is unique to location. Despite the many differences between the United States and Japan, the strongest correlates of poverty in each country involve the proportion of land in an area that is forested. Particularly because these results mirror the findings from the one previous study that included this variable, future research must give greater attention to this explicitly environmental variable, as well as examining some of the possible reasons for the relationship. 相似文献

Five experiments were conducted to examine the performance of young infants on above versus below categorization tasks. Experiments 1 and 2 showed that infants did not form abstract categorical representations for above and below when familiarized with different objects depicted in a constant spatial relation relative to a horizontal bar and tested on a novel object depicted in the familiar and novel spatial relation. Experiments 3 through 5 examined perceptual‐attentional distraction versus conceptually based generalization explanations for young infant performance in the object‐variation version of the above‐below categorization task. Experiments 3 and 4 demonstrated that infants still did not form abstract categorical representations for above and below when object variation was removed from the familiarization trials or when object novelty was reduced during the preference test trials. However, Experiment 5 showed that 3‐ and 4‐month‐olds succeeded on the above versus below categorization task when familiarized with object variation and preference tested with a familiar versus novel object‐bar relation. These results indicate that young infants can form categorical representations for above and below in the object‐variation version of the above‐below categorization task, but that such representations are specific to the particular objects presented. Young infant performance in the object‐variation version of the above‐below categorization task thus reflects a conceptually based generalization limit rather than a problem of perceptual‐attentional distraction. 相似文献

Family-based prevention programs have shown promise in preventing drug use and antisocial behavior in high-risk youth. Multidimensional family prevention (MDFP) is an intensive, family-based counseling program in which a family-specific prevention agenda is crafted with each family. This collaborative, individualized approach to intervention requires a high degree of engagement on the part of families. The main challenges of engagement are discussed, and the main features of an engagement strategy are described: capturing the interest of the family and assessing risk and protective factors within the specific ecological context of the family in order to create a working agenda for preventive intervention. 相似文献

Using annual cross‐sectional data from Monitoring the Future, the present study examined trends in high school seniors' current and anticipated civic participation and beliefs over a 30‐year period. We examined overall trends and patterns based on youths' post‐high school educational plans. Findings point to declines in recent cohorts' involvement in conventional and alternative forms of engagement but greater involvement in community service. Regardless of period, the majority of youth said they intended to vote when eligible, but few expressed trust in the government or elected officials. All civic indicators showed significant differences based on youths' college aspirations: Youth who planned to graduate from a 4‐year college were more civically inclined than their peers with 2‐year or no college plans. 相似文献

Assortative mating is of interest to both theoretical and applied social scientists. Previous research is based almost entirely
on married couples and parents. In this paper we use data from the NSFG to examine assortative mating among unmarried parents
in the US and to examine the robustness of estimates of nonresident fathers' income based on assortative mating assumptions.
We find that never married parents are similar, though not identical, to married parents in their choice of partners. White
unmarried women are much more likely to have a child with a non-white male than white married women. On the other hand, unmarried
women are more likely than married women to have a child with a more educated male.

We consider a broad set of variables used by social scientists and clinicians to identify the leading predictors of five‐year survival among American adults. We address a question not considered in earlier research: Do the strongest predictors of survival vary by age, sex or race/ethnicity? The analysis uses hazard models with 30 well‐established predictors to examine five‐year survival in the National Health and Nutrition Examination Survey. We find that the simple measure of self‐assessed health and self‐reported measures of functional ability and disability are the strongest predictors in all demographic groups, and are generally ranked considerably higher than biomarkers. Among the biomarkers, serum albumin is highly ranked in most demographic groups, whereas clinical measures of cardiovascular and metabolic function are consistently among the weakest predictors. Despite these similarities, there is substantial variation in the leading predictors across demographic groups, most notably by race and ethnicity 相似文献

Significant differences exist in Americans’ support for force between the 1991 Persian Gulf War and 2003 Iraq War, even when holding all demographic variables constant. Nearly every group decreased their support from 1991 to 2003, including men and women, Whites and racial minorities, people with high school degrees or higher, nearly all age categories, and Democrat and Independent affiliated individuals. When examining potential causes for decreased support in the 2003 Iraq War, the “nature of the conflict” presents the strongest argument and evidence. The Persian Gulf War aimed to force the Iraqi army from Kuwait, while the Iraq War was aimed at changing the governmental regime of Iraq. The latter conflict was less socially acceptable than the former to Americans. These differences between the conflicts are the best explanation for the change in support, while other explanations, including the changing composition of the population and a less pro-military populace, are insufficient. 相似文献
