1937年上海“纱交风潮”系上海纱布交易所爆发的影响巨大且后果最严重的一次风潮。此次风潮的起因是多方面的,其中最根本的原因是孔家官僚资本为获取巨利插手纱交、操纵市场、大搞投机活动。这场风潮促使国民政府颁布《取缔上海纱布交易所投机办法》,并对此次风潮进行“澈查”,然“澈查”结果却虎头蛇尾。由此看出,国民政府与官僚资本的密切关系,即官僚资本已凭借各种超经济特权在国民经济中取得了独特的优势地位。 相似文献

Bayesian networks for imputation 总被引:1,自引:0,他引:1

Summary. Bayesian networks are particularly useful for dealing with high dimensional statistical problems. They allow a reduction in the complexity of the phenomenon under study by representing joint relationships between a set of variables through conditional relationships between subsets of these variables. Following Thibaudeau and Winkler we use Bayesian networks for imputing missing values. This method is introduced to deal with the problem of the consistency of imputed values: preservation of statistical relationships between variables ( statistical consistency ) and preservation of logical constraints in data ( logical consistency ). We perform some experiments on a subset of anonymous individual records from the 1991 UK population census. 相似文献

社会学视野下的单亲家庭 总被引:7,自引:0,他引:7
李婵 《湖南人文科技学院学报》2004,(5):23-25
随着人们家庭婚姻观念的转变,离婚率的迅速上升,单亲家庭也日益增多。在社会学的视野下,单亲家庭作为一种特殊的家庭形式,它的出现在一定程度上是社会文化发展的必然。但是因为社会法律制度和意识形态的滞后性,从福利到舆论,社会都没有为单亲家庭提供和完整家庭一样的待遇,以致给子女、父母以及社会都带来了各种严重的社会问题。 相似文献

In non-experimental research, data on the same population process may be collected simultaneously by more than one instrument.
For example, in the present application, two sample surveys and a population birth registration system all collect observations
on first births by age and year, while the two surveys additionally collect information on women’s education. To make maximum
use of the three data sources, the survey data are pooled and the population data introduced as constraints in a logistic
regression equation. Reductions in standard errors about the age and birth-cohort parameters of the regression equation in
the order of three-quarters are obtained by introducing the population data as constraints. A halving of the standard errors
about the education parameters is achieved by pooling observations from the larger survey dataset with those from the smaller
survey. The percentage reduction in the standard errors through imposing population constraints is independent of the total
survey sample size. 相似文献

The aim of this article is to foster an awareness of the need for gender‐sensitive research in the context of the methodological and ethical challenges posed by such research. We trace the development of gender sensitivity and masculinity in social work practice and research and connect this to an overview of the issues posed by research on sensitive topics. Reflecting on a research project involving Chinese male sexual abuse survivors, we draw conclusions illustrating and proposing a range of methodological practices and ethical safeguards. We underscore the importance of gender‐sensitivity in performing research on sensitive topics with men in a Chinese community. 相似文献

The purpose of this study was to examine the overall impact of four leadership styles (charismatic, directive, participative, and supportive) in four Confucian Asian countries, China, Japan, South Korea, and Singapore, by reviewing recent studies conducted in those countries. By reviewing 38 studies selected from 430 studies published between 2005 and 2016, we identify the impact of the four leadership styles in the four Asian countries. We start with the research question and purpose, and then propose criteria for selecting the relevant recent studies followed by a review of cultural heritage and its influence on leadership in the four Asian countries. We summarize and review the studies and, finally, discuss the theoretical and practical contributions of this study. 相似文献

Interactive Computer Based Instruction (CBI) systems involve teaching strategies to facilitate greater response opportunities during training in an effort to improve learner performance. The current study investigated the effect of online staff training videos with and without overt response requirements on posttest and maintenance test scores across six block-randomized instructional modules for four employees of a university located in the southeastern region of the United States. The overt response consisted of multiple-choice questions administered throughout select teaching modules using an alternating treatment design. Findings suggest that learning occurred as a result of the CBI training; however, the effectiveness of the overt response system varied across individuals, with no discernible differentiation between learning gains associated with response requirements. Other areas of research for expanding the efficacy of CBI and overt response systems are highlighted. 相似文献
