The Impact of Adolescents' Classroom and Neighborhood Ethnic Diversity on Same‐ and Cross‐Ethnic Friendships Within Classrooms 下载免费PDF全文

This study examines how classroom and neighborhood ethnic diversity affect adolescents' tendency to form same‐ versus cross‐ethnic friendships when they enter middle school. Hypotheses are derived from exposure, conflict, and constrict theory. Hypotheses are tested among 911 middle school students (43 classrooms, nine schools) in the Netherlands. Multilevel (p2) social network analyses show that students were more likely to engage in same‐ethnic rather than cross‐ethnic friendships. In line with conflict theory, greater classroom and neighborhood diversity were related to stronger tendencies to choose same‐ethnic rather than cross‐ethnic friends, among both ethnic majority and minority students. Diversity did not hamper reciprocity, as students in more ethnically diverse classrooms were even more likely to reciprocate friendships. 相似文献

The paper reports an input-output analysis of energy flows in the Federal Republic of Germany (FRG) economy which includes a capital flows matrix. Results include a quantification of the interdependence of energy with other manufacturing resources, and an estimate of energy and energy-related costs of commodities. An approximate method of estimating the effects of changes in technical coefficients and primary input costs is assessed. 相似文献

ABSTRACTIn this paper, we derive the Bayes estimators of functions of parameters of the size-biased generalized power series distribution under squared error loss function and weighted square error loss function. The results of size-biased GPSD are then used to obtain particular cases of the size-biased negative binomial, size-biased logarithmic series, and size-biased Poisson distributions. These estimators are better than the classical minimum variance unbiased estimators in the sense that they increase the range of the estimation. Finally, an example is provided to illustrate the results and a goodness of fit test is done using the maximum likelihood and Bayes estimators. 相似文献

In this study, we investigate to what extent macro-economic circumstances and social protection expenditure affect economic deprivation. We use three items from round five of the European Social Survey (2010–2011) to construct our latent outcome variable, which we label economic deprivation in the 3 years before 2010–2011. The results of our linear multilevel regression analyses indicate that in countries that perform worse economically, individual experiences of economic deprivation are more prevalent: the stronger the rise in the unemployment rate and the lower a country’s wealth, the more economic deprivation individuals experience. We also find that in countries with high levels of social protection, people experience less economic deprivation as compared to countries with low levels of social protection. In turn, adverse economic conditions in a country temper these positive outcomes of social welfare arrangements. Finally, our study reveals that the strength of the relationship between a low income and economic deprivation strongly varies according to the economic circumstances in a country and the generosity of the welfare state. 相似文献

Although eye tracking has been used for decades, it has gained popularity in the area of sex research only recently. The aim of this article is to examine the potential merits of eye tracking for this field. We present a systematic review of the current use of video-based eye-tracking technology in this area, evaluate the findings, and identify future research opportunities. A total of 34 relevant studies published between 2006 and 2014 were identified for inclusion by means of online databases and other methods. We grouped them into three main areas of research: body perception and attractiveness, forensic research, and sexual orientation. Despite the methodological and theoretical differences across the studies, eye tracking has been shown to be a promising tool for sex research. The article suggests there is much potential for further studies to employ this technique because it is noninvasive and yet still allows for the assessment of both conscious and unconscious perceptional processes. Furthermore, eye tracking can be implemented in investigations of various theoretical backgrounds, ranging from biology to the social sciences. 相似文献

Previous research demonstrated that viewers’ judgments of an interviewee are influenced by the nonverbal behavior of the interviewer.
In studies of this media bias effect, judges view a short political interview with a friendly or a hostile interviewer, and
then rate their impressions of the interviewee, whose behavior remains identical in all conditions. The present research utilizes
the same design and materials to explore potential cognitive remedies, to investigate the effect of attitude similarity on
media bias, and to meta-analyze seven replications of the media bias effect. In Study 1, a cognitive remedy in the form of
an instruction to ignore the interviewer neutralized and even reversed the media bias effect. In Study 2, insertion of a brief
segment depicting a “beaming” and relaxed interviewee also reversed the media bias effect. Study 3 demonstrated that negative
ratings of the interviewee due to interviewer’s hostility were intensified when respondents considered the interviewee as
“one of them” politically, and disappeared when he was perceived as “one of us”. Study 4 demonstrated the consistency of the
media bias effect by meta-analyzing seven replications in different countries. Implications for nonverbal research and for
media research concerning the consistency of the media bias effect and its amenability to remedy are discussed. 相似文献

This study examined media exposure as an explanatory factor for individual and cross-national differences in self-assessed general health. In studying media exposure, traditional media (television, radio, and newspapers) and contemporary media (internet) were separately considered. Aside from hypotheses about the relation between media exposure and general health, we also tested hypotheses regarding the mediating role of social isolation and mean world syndrome as well as the moderating role of different media systems across countries. Therefore, we used European Social Survey 2010, covering 25 European countries (n = 36,692). The results of our multilevel regression analyses indicated that exposure to television was negatively related to general health, whereas exposure to radio and newspapers were positively related to health. For contemporary media, findings indicated consistent positive relations between internet exposure and health across. Furthermore, limited support was found for the mediating role of social isolation and the mean world syndrome in the link between media exposure and health. Across media systems, findings for the relations between exposure to the various types of media and health proved to be robust. 相似文献
