The current study uses an accelerated longitudinal design to examine the role of three dimensions of academic engagement (behavioral, relational, and cognitive) in explaining the influence of English language proficiency on newcomer immigrant youths' academic performance across adolescence. The sample included 354 youth from Central America, China, the Dominican Republic, Haiti, and Mexico. As established with other populations, the behavioral, relational, and cognitive dimensions of academic engagement were closely associated to one another and significantly contributed to academic performance. Mediation analyses revealed that immigrant youth with limited English language proficiency were more likely to experience low levels of relational and behavioral engagement, which contributed to lower levels of academic performance over time. 相似文献

This article presents data from a national survey on social work intervention in cases of wife assaults in Singapore. The survey was conducted from March to July 1992 among 510 citizens, educated and over 17 years old. Trained interviewers during a 20-minute interview used a structured questionnaire divided into six major sections. Respondents were asked to choose from the four possible responses, namely: 1) work together with couple to solve their problems; 2) help the wife find another place to stay; 3) help the wife obtain a court order; and 4) help the wife get a divorce. Demographic variables are included in the analysis. About 92.4% of the respondents indicated that social workers should limit their intervention to ?work with the couple? in dealing with cases of minor assault occurring for the first time. About 35.8% opted to help the wife obtain a court order, and 22.3% chose separation or divorce in minor assaults. Majority suggested that social workers should help the wife obtain a court order and separation on major assaults. Findings suggest that social services in Singapore should focus their programs on battered women solely on conciliatory services outside the legal system. 相似文献

Support vector machine (SVM) is sparse in that its classifier is expressed as a linear combination of only a few support vectors (SVs). Whenever an outlier is included as an SV in the classifier, the outlier may have serious impact on the estimated decision function. In this article, we propose a robust loss function that is convex. Our learning algorithm is more robust to outliers than SVM. Also the convexity of our loss function permits an efficient solution path algorithm. Through simulated and real data analysis, we illustrate that our method can be useful in the presence of labeling errors. 相似文献

Marriage‐Market Constraints and Mate‐Selection Behavior: Racial,Ethnic, and Gender Differences in Intermarriage

Despite theoretical consensus that marriage markets constrain mate‐selection behavior, few studies directly evaluate how local marriage‐market conditions influence intermarriage patterns. Using data from the American Community Survey, the authors examine what aspects of marriage markets influence mate selection, assess whether the associations between marriage‐market conditions and intermarriage are uniform by gender and across pan‐ethnic groups, and investigate the extent to which marriage‐market conditions account for group differences in intermarriage patterns. Relative group size is the most salient and consistent determinant of intermarriage patterns across pan‐ethnic groups and by gender. Marriage‐market constraints typically explain a larger share of pan‐ethnic differences in intermarriage rates than individual traits, suggesting that scarcity of co‐ethnic partners is a key reason behind decisions to intermarry. When faced with market constraints, men are more willing or more successful than women in crossing racial and ethnic boundaries in marriage. 相似文献

The present research proposed that one social‐cognitive root of adolescents' willingness to use relational aggression to maintain social status in high school is an entity theory of personality, which is the belief that people's social status‐relevant traits are fixed and cannot change. Aggregated data from three studies (N = 882) showed that first‐year high school adolescents in the United States who endorsed more of an entity theory were more likely to show cognitive and motivational vigilance to social status, in terms of judgments on a novel social categorization task and reports of goals related to demonstrating social status to peers. Those with an entity theory then showed a greater willingness to use relational aggression, as measured by retrospective self‐reports, responses to a hypothetical scenario, and a choice task. Discussion centers on theoretical and translational implications of the model and of the novel measures. 相似文献

To analyze the influence of advertising on the acceptance of press releases, this study examined two national and two local newspapers. The results of this study show that journalists and editors partially consider advertisers while selecting press releases. Specifically, local newspapers give more consideration to advertisers than national newspapers. However, when journalists and editors select press releases, they consider not only advertisers but the newsworthiness of the press releases. 相似文献

Humidifier sterilizers were regarded as innovative and health-promoting products; they were widespread in South Korea until 2011. However, hospitals reported mysterious deaths, and a legal investigation in April 2016 found that hundreds of people have died due to use of the sterilizing disinfectant. This article takes up that topic, discussing the government's role in dealing with the risk regarding the humidifier disinfectant. We pay particular attention to the unequal nature of the uncertainty produced by the distorted socioeconomic structure. Through in-depth interviews with key informants and an examination of relevant documents from the government, civic groups, and newspapers, we find that the government had increasingly acknowledged the risk, yet their inaction failed to stop the high number of casualties, and they have only recently responded proactively. The uncertainty of the risk was unevenly distributed between companies, the government, experts, and citizens. We argue that the proactive and transparent role of the government with the precautionary principle could fix the unequal structure of knowledge production and preserve public health. 相似文献

In this paper, we present large sample properties of a partially linear model from the Bayesian perspective, in which responses are explained by the semiparametric regression model with the additive form of the linear component and the nonparametric component. For this purpose, we investigate asymptotic behaviors of posterior distributions in terms of consistency. Specifically, we deal with a specific Bayesian partially linear regression model with additive noises in which the nonparametric component is modeled using Gaussian process priors. Under the Bayesian partially linear model using Gaussian process priors, we focus on consistency of posterior distribution and consistency of the Bayes factor, and extend these results to generalized additive regression models and study their asymptotic properties. In addition we illustrate the asymptotic properties based on empirical analysis through simulation studies. 相似文献
