The literatures on violence among young men and young women have highlighted the importance of situational context. However, few studies have compared disputes that do not result in violence with those that do, and even fewer have been positioned to investigate the role situational context may play across gender in accounting for these outcomes. Drawing on recent scholarship on gender and violence, this research explores the situational contexts of youth conflicts among African-American adolescent boys and girls. Using a large sample of narrative accounts of 153 violent and nonviolent conflicts, we examine how youth describe the issues of contention in their conflicts, how these relate to the situational contexts in which conflicts emerge, and similarities and differences in the antecedents, contexts, and extent of male and female violence. 相似文献

We report on a novel phenomenon, that is a high-strain-induced reverse martensitic transformation in an ultrafine-grained Ti–36Nb–2Ta–3Zr (wt.%) alloy processed by equal channel angular pressing (ECAP) at room temperature. Our results show that a martensitic transformation from body-centred cubic β matrix to orthorhombic α″ martensite occurs under low-strain ECAP conditions and that a large portion (~34%) of martensite transforms into a matrix phase (i.e. reverse martensitic transformation) with increasing ECAP strain to a high value of 4 (i.e. 6 passes) with a corresponding reduction in the α″-lath thickness and a refinement of grain size in the matrix phase. 相似文献

Dual-process models of the mind, as well as the relation between analytic thinking and religious belief, have aroused interest in recent years. However, few studies have examined this relation experimentally. We predicted that religious belief might be one of the causes of prejudice, while analytic thinking reduces both. The first experiment replicated, in a mostly Muslim sample, past research showing that analytic thinking promotes religious disbelief. The second experiment investigated the effect of Muslim religious priming and analytic priming on prejudice and showed that, although the former significantly increased the total prejudice score, the latter had an effect only on antigay prejudice. Thus, the findings partially support our proposed pattern of relationships in that analytic thinking might be one of the cognitive factors that prevents prejudice, whereas religious belief might be the one that increases it. 相似文献

Research on volunteering behavior has consistently found a positive relationship between religion and volunteering. Using a sample of churchgoing Protestants (N=1,738)from the Religious Identity and Influence Survey we examine the specific influences of religiosity, religious identity, religious socialization, and religious social networks on local volunteer activity in church programs and non-church organizations, as well as general volunteering tendencies. These influences are presented within the theoretical framework of religious capital. Logistic regression techniques were applied to determine the strength of the contribution of these influences while accounting for basic background factors. Findings suggest that churchgoing Protestants are influenced by all measures to some degree, but religiosity (specifically participation in church activities) remains the strongest influence. Significant religious influences overall are most pronounced within the context of church-related volunteering which suggests that churchgoing Protestants exhibit a strong sense of community identity through their local churches. A discussion of these results and their implications for volunteering follows. 相似文献

Relations among finger forces were studied during one-hand and two-hand isometric maximal force production tasks in right- and left-handers. We particularly focused on the phenomena of force deficit during one-hand multi-finger tasks and of bilateral force deficit during two-hand tasks. Ten healthy subjects (five of them left-handed) performed maximal voluntary force production tasks with different finger combinations involving fingers of one of the hands or of both hands together. In one-hand tasks, finger enslaving (forces produced by fingers that were not instructed to produce force) was larger in the dominant hand, while force deficit (drop in individual finger peak force during multi-finger tasks) showed no differences between the hands. An additional drop in finger forces was seen in two-hand tests (bilateral deficit). The magnitude of the bilateral deficit for a hand was larger for tasks involving fewer fingers within the hand and more fingers in the other hand, with a ceiling effect. Smaller bilateral deficit was seen in tasks involving symmetrical finger combinations. In two-hand tasks that could potentially lead to the generation of large total moments in the frontal plane, the hand that was expected to generate larger moments showed larger bilateral deficit, so that the magnitude of the total moment was reduced. These observations suggest that force deficit within a hand and bilateral deficit have different origins but their effects are combined at a certain level of the multi-finger control hierarchy. Bilateral deficit may display task dependence reflecting, in particular, the principle of minimization of secondary moments. A double-representation, mirror-image hypothesis is suggested to provide a neurophysiological basis for the observed patterns of bilateral deficit. 相似文献

The dominant view in the field of lexical access in speech production maintains that selection of a word becomes more difficult as the levels of activation of nontarget words increase--selection by competition. The authors tested this prediction in two sets of experiments. First, the authors show that participants are faster to name pictures of objects (e.g., "bed") in the context of semantically related verb distractors (e.g., sleep) compared with unrelated verb distractors (e.g., shoot). In the second set of experiments, the authors show that target naming latencies (e.g., "horse") are, if anything, faster for within--category semantically close distractor words (e.g., zebra) than for within--category semantically far distractor words (e.g., whale). In the context of previous research, these data ground a new empirical generalization: As distractor words become semantically closer to the target concepts--all else being equal--target naming is facilitated. This fact means that lexical selection does not involve competition, and consequently, that the semantic interference effect does not reflect a lexical level process. This conclusion has important implications for models of lexical access and interpretations of Stroop-like interference effects. 相似文献

This study examined whether a short training in grounding strategies could improve intercultural communication. Forty intercultural dyads (Anglo-Canadians and Mainland Chinese) were randomly assigned to experimental and control groups. Prior to their conversations the experimental groups received 10–15 min training on grounding while the control groups received no training. The trained dyads performed significantly better than the untrained dyads in grounding, speaker presentation and listener recall, thus documenting that the 10–15 min training on grounding was fruitful in improving intercultural communication. Grounding training may open a new avenue for reducing intercultural miscommunication, thus improving information transmission. 相似文献
