中国社会风险解析——群体性事件的社会冲突性质 总被引:25,自引:0,他引:25
群体性事件是我国社会冲突的主要表现形式,无论是客观数据还是主观感知,都显示中国已经处于一个社会冲突事件的高发期.当前,我国社会冲突的主要类型是经济型的直接冲突与社会型的间接冲突.社会冲突在总体上是上升的;冲突的风险源清晰;冲突的主体为利益受损群体与利益获得群体;冲突的性质以经济领域的利益性冲突为主,具有可协调性;冲突的强度与烈度有加剧的趋势;冲突矛盾呈复杂性,处理的社会成本升高;群体性事件开始作为"弱者的武器"被普遍地使用;对社会冲突事件开始由封闭的、僵硬的内部处置到开放的、弹性的公开处理. 相似文献

Background Both ability (measured by power tests) and non‐ability (measured by preference tests) individual difference measures predict academic school outcomes. These include fluid as well as crystalized intelligence, personality traits, and learning styles. This paper examines the incremental validity of five psychometric tests and the sex and age of pupils to predict their General Certificate in Secondary Education (GCSE) test results. Aims The aim was to determine how much variance ability and non‐ability tests can account for in predicting specific GCSE exam scores. Sample The sample comprised 212 British schoolchildren. Of these, 123 were females. Their mean age was 15.8 years (SD 0.98 years). Method Pupils completed three self‐report tests: the Neuroticism–Extroversion–Openness‐Five‐Factor Inventory (NEO‐FFI) which measures the ‘Big Five’ personality traits, ( Costa & McCrae, 1992 ); the Typical Intellectual Engagement Scale ( Goff & Ackerman, 1992 ) and a measure of learning style, the Study Process Questionnaire (SPQ; Biggs, 1987 ). They also completed two ability tests: the Wonderlic Personnel Test ( Wonderlic, 1992 ) a short measure of general intelligence and the General Knowledge Test ( Irving, Cammock, & Lynn, 2001 ) a measure of crystallized intelligence. Six months later they took their (10th grade) GCSE exams comprising four ‘core’ compulsory exams as well as a number of specific elective subjects. Results Correlational analysis suggested that intelligence was the best predictors of school results. Preference test measures accounted for relatively little variance. Regressions indicated that over 50% of the variance in school exams for English (Literature and Language) and Maths and Science combined could be accounted for by these individual difference factors. Conclusions Data from less than an hour's worth of testing pupils could predict school exam results 6 months later. These tests could, therefore, be used to reliably inform important decisions about how pupils are taught. 相似文献

This experiment exposed a sample of U.S. undergraduates (43 men, 40 women) to suggestively or conservatively clad virtual females who exhibited either responsive, high eye gaze or nonresponsive, low gaze in an immersive virtual environment. Outside the virtual world, men and women who encountered a highly stereotypical character—a suggestively clad, high gaze agent (“vamp”) or conservatively clad, low gaze character (“virgin”)—demonstrated more sexism and greater rape myth acceptance than participants who saw a suggestively clad nonresponsive or conservatively clad, responsive character. Results suggest that gender-stereotypical virtual females enhance negative attitudes toward women, whereas those that violate expectations and break stereotypes do not. 相似文献

Police services in a number of Australian states and overseas jurisdictions have begun to implement or consider random road-side drug testing of drivers. This paper outlines research conducted to provide an estimate of the extent of drug driving in a sample of Queensland drivers in regional, rural and metropolitan areas. Oral fluid samples were collected from 2657 Queensland motorists and screened for illicit substances including cannabis (delta 9 tetrahydrocannibinol [THC]), amphetamines, ecstasy, and cocaine. Overall, 3.8% of the sample (n = 101) screened positive for at least one illicit substance, although multiple drugs were identified in a sample of 23 respondents. The most common drugs detected in oral fluid were ecstasy (n = 53), and cannabis (n = 46) followed by amphetamines (n = 23). A key finding was that cannabis was confirmed as the most common self-reported drug combined with driving and that individuals who tested positive to any drug through oral fluid analysis were also more likely to report the highest frequency of drug driving. Furthermore, a comparison between drug vs. drink driving detection rates for one region of the study, revealed a higher detection rate for drug driving (3.8%) vs. drink driving (0.8%). This research provides evidence that drug driving is relatively prevalent on Queensland roads, and may in fact be more common than drink driving. This paper will further outline the study findings’ and present possible directions for future drug driving research. 相似文献

在婴儿早期的视觉经验中,面孔是最特殊的一类刺激,小婴儿从出生开始就喜欢看面孔,这种现象称为面孔偏好。面孔偏好的发展反映了婴儿知觉能力的发展规律,具有重要的社会化意义。该文系统介绍了线性系统模型、右脑优势模型、CONSPEC理论、视觉模块理论和非特异化识别理论5种最主要的婴儿面孔偏好理论,并对这些理论的区别和联系进行了探讨。最后,对面孔偏好研究的新趋势和未来方向进行了评价和展望 相似文献
