公元13世纪回回人从灿烂的阿拉伯伊斯兰文化的高峰走来,进入高度发达的中国的汉文化领域。阿拉伯伊斯兰文化是形成发展中的回回民族的一种文化形式,它从真主独一的信仰及其功修、伦理道德、价值观念、生活方式等方面维护着形成中的回回民族的民族的同一性。在汉文化面前如何保存自己固有的阿拉伯伊斯兰文化,使其继续传承,不致中断,这是摆在回回人面前的新问题。同时,为了民族的生存发展,回回人必须学习汉文化,以适应中国传统社会,以被中国传统社会所接纳。而汉文化是一 相似文献

中国多民族"混居"自治区域权利样态研究 总被引:5,自引:0,他引:5
多民族“混居”自治区域的各个民族政治、经济发展不平衡,历史文化也存在差异,对权利的理解和要求必然有所不同。过去我国对多民族“混居”自治区域往往重点关注政治权利的发展,对经济等权利的发展重视不够;同时多强调民族权利的共性,对各民族之间的权利差异有意无意给予回避,导致人们的权利意识发育不良。随着社会的发展,多民族“混居”自治区域的权利意识必定增长,由此也会带来权利资源的严重短缺,并引发各民族之间的权利冲突。多民族“混居”自治区域具有特殊性,其权利也应有其特殊的内容,它关系到民族的发展和国家的繁荣昌盛。 相似文献

This research provides a generalized framework to disaggregate lower-frequency time series and evaluate the disaggregation performance. The proposed framework combines two models in separate stages: a linear regression model to exploit related independent variables in the first stage and a state–space model to disaggregate the residual from the regression in the second stage. For the purpose of providing a set of practical criteria for assessing the disaggregation performance, we measure the information loss that occurs during temporal aggregation while examining what effects take place when aggregating data. To validate the proposed framework, we implement Monte Carlo simulations and provide two empirical studies. Supplementary materials for this article are available online. 相似文献

Most models of investor behavior assume a time-state independent utility function and result in a deterministic solution where a given set of inputs uniquely specifies the decision. In contrast, a state preference model using a time-state dependent utility function is derived in this paper. The model allows the investment choice decision to be analyzed in a game theoretic context. The general solution is a mixed strategy which allows for a probabilistic interpretation of the decision. The approach presented in this paper can accommodate anomalies such as intransitivity of preference and satisficing as rational behavior. An example of a possible implementation is given along with interpretations of the outcomes. 相似文献

Decision support system (DSS) researchers and designers continue to look for unstructured organizational tasks where there is a critical need for intelligent computer-based support. One such decision task is information requirements determination. Requirements determination is recognized as the most crucial phase of the systems development life cycle. Unfortunately, most methodologies and CASE tools focus only on how to specify the requirements once they are determined. There is very little computer support for the process of determining requirements. This paper discusses the conceptual design and development of a knowledge-based DSS to support information analysts in the critical decision task of determining requirements for the design of effective information systems. The expert modeling support system has the expertise to assist the analyst in studying the organization as a whole and in modeling the system under study in the context of the overall organization's goals and needs. The focus of the paper is on the problems associated with building the knowledge base component of the intelligent decision support system. A prototype implementation of the system is described. 相似文献

郑国东迁,以今新郑为其新都,重要的原因在于新郑有作为都城的优越生态环境。而郑国东迁后的生态环境也经历了由早期的良好状况到后期的严重破坏的变化,导致这种变化的原因是多方面的和复杂的。生态环境恶化产生的严峻后果又使郑国的统治者有所醒悟,并采取了一些保护生态环境的措施。这种转变是发人深省的,它对于我们今天正在进行的经济建设很有借鉴价值。 相似文献

Prospect theory by Kahneman and Tversky [7] is tested in a deterministic multiple criteria decision-making context. In two experiments conducted in classroom settings subjects made pairwise preference comparisons of condominiums for sale. The results of the experiments indicate that the traditional value model did not explain the subjects' revealed preferences as well as the prospect model. We conclude that prospect theory is a reasonable model of choice for many individuals in such a context. 相似文献

The purpose of this study is to test the effects of narratives in crisis communication. This research assesses how organizations benefit from using stories in their media responses, relative to sharing nonnarrative information. The theory of crisis response narratives (Heath, 2004) holds that ethical narratives are effective because they enhance trustworthiness, attitudes toward the spokesperson, and identification with the spokesperson. Normative crisis communication theory exhorts disclosing truthful information rather than spinning. In an online experiment, participants (N = 365) watched a news interview in which a scandalized company’s spokesperson responded to a journalist’s questions with (a) ethical narratives, (b) unethical (spin) narratives, or (c) nonnarrative information. Multiple mediator modeling assessed identification with the spokesperson, attitudes toward the spokesperson, and perceived trustworthiness of the spokesperson. Results indicate ethical narratives are more effective than unethical narratives. However, nonnarrative information most effectively enhances trustworthiness and bolsters identification. 相似文献

发展生态模型是西方儿童虐待成因研究的重要理论框架,但国内对此缺少系统性介绍。该理论认为,儿童虐待产生自互动个体与嵌套生态系统层面间的交互影响,它主要以生态系统理论为理论基础,并以“生态整合模型”和“生态交互模型”为代表性理论模型。该理论具有重要的方法论意义,它可促使研究者突破单因素变量研究的窠臼,并转向多因素共构视角去理解儿童虐待成因;同时,也为儿童虐待治理实践提供了多因素和多层次的系统干预视角。该理论的出现丰富了儿童虐待研究者的理论想象力,可为我国家庭、学校等场域的儿童虐待和儿童保护研究和干预提供启示。 相似文献
