Youth in alternative schools often engage in high rates of risk behaviors for AIDS and violence. This study included 42 youth, ages 13 to 18, from alternative schools in San Diego, CA, and tested the effectiveness of behavioral skills training based on the Behavioral‐Ecological Model. Two interventions were evaluated: one teaching condom use skills and the other teaching anger management skills. Changes in most skills were significant at postintervention but were not maintained at 6 months. Few risk‐related attitudes or behaviors improved at 6 months for either group.  相似文献

Applying a unifying theoretical framework of high‐quality work relationships, we conducted a set of 3 complementary studies that examined whether high‐quality mentoring relationships can buffer employees from the negative effects of ambient discrimination at work. Integrating relational mentoring with relational systems theory, we first examined whether the presence of a high‐quality mentoring relationship buffers employees in a sample of 3,813 workers. In support of the “mentors‐as‐buffers” hypothesis, we found that employees who witnessed or were aware of racial discrimination at work had lower organizational commitment than those not exposed, but employees with high‐quality mentoring relationships experienced less loss of commitment than those lacking mentors. We then examined the specific buffering behaviors used by mentors in high‐quality relationships and whether these behaviors were effective for other work relationships and outcomes. Applying Kahn's typology, we developed and validated a measure of high‐quality relational holding behaviors in a sample of 262 workers. Using this measure in a third sample of 557 workers, we found that mentors buffer by providing holding behaviors, but we did not find this buffering effect when supervisors or coworkers provided holding behaviors. This potent mentor buffering effect held across a range of outcomes, including organizational commitment, physical symptoms of stress, insomnia, and stress‐related absenteeism. These studies suggest that mentoring may be a singularly effective relationship that offers a safe harbor for employees faced with ambient discrimination at work.  相似文献

Gerald Dworkin’s overlooked defense of legal moralism attempts to undermine the traditional liberal case for a principled distinction between behavior that is immoral and criminal and behavior that is immoral but not criminal. According to Dworkin, his argument for legal moralism “depends upon a plausible idea of what making moral judgments involves.” The idea Dworkin has in mind here is a metaethical principle that many have connected to morality/reasons internalism. I agree with Dworkin that this is a plausible principle, but I argue that some of the best reasons for accepting it actually work against his enforcement thesis. I propose a principled distinction between the immoral-and-criminal and the immoral-but-not-criminal, and argue that a principle at least very much like it must be correct if the metaethical principle Dworkin avows is correct.  相似文献

Many variables that are analyzed by social scientists are nominal in nature. When missing data occur on these variables, optimal recovery of the analysis model's parameters is a challenging endeavor. One of the most popular methods to deal with missing nominal data is multiple imputation (MI). This study evaluated the capabilities of five MI methods that can be used to treat incomplete nominal variables: multiple imputation with chained equations (MICE) using polytomous regression as the elementary imputation method; MICE based on classification and regression trees (CART); MICE based on nested logistic regressions; the ranking procedure described by Allison (2002 Allison, P. D. (2002). Missing data. Thousand Oaks, CA: Sage Publications. https://doi.org/10.4135/9780857020994.n4[Crossref] [Google Scholar]); and a joint modeling approach based on the general location model. We first motivate our inquiry with an applied example and then present the results of a Monte Carlo simulation study that compared the performance of the five imputation methods under conditions of varying sample size, percentage of missing data, and number of nominal response categories. We found that MICE with polytomous regression was the strongest performer while the Allison (2002 Allison, P. D. (2002). Missing data. Thousand Oaks, CA: Sage Publications. https://doi.org/10.4135/9780857020994.n4[Crossref] [Google Scholar]) ranking procedure and MICE with CART performed poorly in most conditions.  相似文献

Although the mapping between form and meaning is often regarded as arbitrary, there are in fact well‐known constraints on words which are the result of functional pressures associated with language use and its acquisition. In particular, languages have been shown to encode meaning distinctions in their sound properties, which may be important for language learning. Here, we investigate the relationship between semantic distance and phonological distance in the large‐scale structure of the lexicon. We show evidence in 100 languages from a diverse array of language families that more semantically similar word pairs are also more phonologically similar. This suggests that there is an important statistical trend for lexicons to have semantically similar words be phonologically similar as well, possibly for functional reasons associated with language learning.  相似文献

This study introduces the Sentiment Analysis and Cognition Engine (SEANCE), a freely available text analysis tool that is easy to use, works on most operating systems (Windows, Mac, Linux), is housed on a user’s hard drive (as compared to being accessed via an Internet interface), allows for batch processing of text files, includes negation and part-of-speech (POS) features, and reports on thousands of lexical categories and 20 component scores related to sentiment, social cognition, and social order. In the study, we validated SEANCE by investigating whether its indices and related component scores can be used to classify positive and negative reviews in two well-known sentiment analysis test corpora. We contrasted the results of SEANCE with those from Linguistic Inquiry and Word Count (LIWC), a similar tool that is popular in sentiment analysis, but is pay-to-use and does not include negation or POS features. The results demonstrated that both the SEANCE indices and component scores outperformed LIWC on the categorization tasks.  相似文献

The authors examined gender differences in the cognitive strategies that children use when they learn how to play a video game. They interviewed 2nd- and 5th-grade boys and girls about how often they played video games and what they did "when learning how to play a video game." The children's responses to the latter question were categorized as either internally or externally oriented (i.e., reading a manual vs. asking for help, respectively). The results indicated that more frequent players and older children were more likely to cite internally based strategies. No main effects of gender were found for the proportions of the internally vs. externally based strategies that were cited.  相似文献

An experiment was done to examine the control heuristic perspective on illusory control and the effects of motives on control judgments, using a computer task similar to the light onset task used in previous research. Desire for the outcome and reinforcement were manipulated. As predicted from a control heuristic perspective, the effect of level of reinforcement on judgments of personal control was mediated by the measure of perceived connection: the perception of the number of positive confirming cases. Motives increased illusions of control, but only in the high reinforcement condition. A mediational analysis that examined how motives affect control judgments found that when the motive to get the outcomes was high, participants had higher estimates of having acted intentionally and these estimates partially mediated the relationship between the motivation manipulation and judgments of control. It appears that perceptions of connection mediate the relationship between reinforcement and illusory control, while judgments of intentionality partially mediate the effect of motives for control and illusory control.  相似文献

Previous studies have shown that interference from flanking distractors can be modulated by the object organization of the scene. The experiments reported here test for object-based attention under conditions of positional certainty, which allow a narrow focus of attention to the target. Prior research has suggested that object-based attention does not arise in these circumstances, but the experiments presented here show that object-based attention can still appear if previous experience with the stimuli leads participants to interpret the stimulus pattern as two separate objects. Two control experiments demonstrate that the appearance of object-based attention is not due simply to a widening of the focus of spatial attention. The presence of object-based attention in such a focused-attention task argues against Shomstein and Yantis's (2002) proposed explanation of object-based attention based on priority in the order of visual search.  相似文献
