我国各民族之间的差异、民族区域自治制度及其自治权的存在是我国区域刑事法律冲突产生的基本原因,而通过制定顾全大局、兼顾特别的变通性、补充性刑法规范,可缓解这一冲突;通过加快少数民族地区的发展步伐,逐步消除民族之间的政治、经济、文化上的差距,进而达到彻底消除这一冲突,实现法制统一的良好局面。  相似文献

Annual concentrations of toxic air contaminants are of primary concern from the perspective of chronic human exposure assessment and risk analysis. Despite recent advances in air quality monitoring technology, resource and technical constraints often impose limitations on the availability of a sufficient number of ambient concentration measurements for performing environmental risk analysis. Therefore, sample size limitations, representativeness of data, and uncertainties in the estimated annual mean concentration must be examined before performing quantitative risk analysis. In this paper, we discuss several factors that need to be considered in designing field-sampling programs for toxic air contaminants and in verifying compliance with environmental regulations. Specifically, we examine the behavior of SO2, TSP, and CO data as surrogates for toxic air contaminants and as examples of point source, area source, and line source-dominated pollutants, respectively, from the standpoint of sampling design. We demonstrate the use of bootstrap resampling method and normal theory in estimating the annual mean concentration and its 95% confidence bounds from limited sampling data, and illustrate the application of operating characteristic (OC) curves to determine optimum sample size and other sampling strategies. We also outline a statistical procedure, based on a one-sided t-test, that utilizes the sampled concentration data for evaluating whether a sampling site is compliance with relevant ambient guideline concentrations for toxic air contaminants.  相似文献

凌濛初<转运汉巧遇洞庭红>通过对金老汉藏财失财和文若虚随人出海,两次巧遇发财机会陡然暴富故事的描写,反映了明代中叶以后商业发展的具体场景,反映了关于相互需求的贸易原理和资本增殖的思想.通过文若虚形象的塑造,反映了作者经商和为人相统一的思想.从故事可知,明中叶后商业发展已经有了一定的规模和规范,但也还有一些不利于商业贸易更大发展的因素,如储运和金融手段的滞后等.  相似文献

This study examined the processes that underlie the association between trait expressiveness and marital satisfaction. A total of 168 newlywed couples participated in a four‐wave, 13‐year longitudinal study of marriage. Cross‐sectional and longitudinal path analyses suggested that expressiveness promotes satisfaction by leading spouses to engage in affectionate behavior and by leading them to idealize their partner. Expressive people formed idealized images of their partner because they brought out the best in their partner's behavior and because they interpreted their partner's behavior in a favorable light. The study extends previous research by showing that the benefits of trait expressiveness extend into the second decade of marriage and by providing a plausible explanation of the connections between trait expressiveness and marital satisfaction.  相似文献

Religious affiliation and the family   总被引:1,自引:0,他引:1  
The process of religious affiliation is mediated by institutions such as the family, which provide a network of ties to the public sphere. Variations in the likelihood of those with no religious affiliation in high school (N=900) becoming church members by the time they reach 30 are explained in terms of a combination of individual attributes, such as educational and spatial mobility, and changes in structural location, such as the transition to marital and parental status. Panel data from the Career Development Study show that women's chances of affiliation are more affected than are men's by parents' religious homogamy, getting married, and having children.  相似文献

What do we mean by progress and cumulation in the social and human sciences? Recent thinking in the philosophy and history of science has led to an abandonment of some versions of logical positivism and of verificationism that had a strong deductive and theory testing orientation. What is to replace them is less clear. This paper argues that progress and cumulation can be seen as a process of evaluation and retention within an epistemic community. Scholarly disciplines differ in their social structure and in their epistemic and normative commitments. Since sociology is a fragmented discipline, progress and cumulation differ within its multiple subdisciplines, which to varying extents represent epistemic communities. Brief sketches of progress (advance) and cumulation in several subdisciplines are offered.  相似文献

唐代狩猎诗论   总被引:1,自引:0,他引:1  
刘贵华 《唐都学刊》2005,21(3):14-17
唐代狩猎诗数量虽不多,但作者涉及面广,无疑是辉煌灿烂的唐诗中一道独特亮丽的风景线。唐代狩猎诗创作的繁荣,与唐代朝野普遍尚猎的风尚及文人入幕、从军边塞活动密切相关。唐人狩猎诗内容丰富,形式多样,特点鲜明,于中还透露出崇猎尚武、积极进取的时代精神。  相似文献

This article uses data from 50 qualitative interviews with female part‐time workers in low‐level jobs in Britain to illustrate their attitudes, orientations and aspirations towards paid work. The research reports two main findings. Firstly, even female part‐time workers at the bottom end of the occupational structure are not a homogeneous group of workers. Secondly, they are not all highly satisfied with their jobs. The article argues that many women (especially those in working‐class households) still do not have a genuine choice between ‘family work’ and ‘market work’. It concludes by presenting a theoretical model of orientations to work.  相似文献

过失犯罪的发生在于人在认知活动中对引起过失犯罪的危险的注意的欠缺。注意是一种伴随着认知过程中的具有“前置”性的心理状态。人认识任何事物,都要首先对该事物施加注意,没有对某事物的注意就不能对其认知。因此,各种心理因素影响认知首先就要影响注意。错觉、情绪和情感、不良意志品质和思维品质、遗忘等心理影响注意,改变注意的指向,对应当注意避免的危险没有注意,或者没有充分注意,或者不能注意时,就造成了注意的欠缺,从而构成过失犯罪。注意欠缺的类型可以划分为转移型的注意欠缺、分散型的注意欠缺、不能型注意欠缺、拒斥型的注意欠缺。  相似文献
