Some Properties of Past Entropy and their Applications

In the context of information theory, measure of uncertainty in past lifetime distribution has been proposed by Di Crescenzo and Longobardi (J Appl Probab 39:434–440, 2002). In this paper, we study some ordering and aging properties in terms of past entropy (based on past lifetime) and develop some characterization results. Some discrete distribution results are also addressed here.     

Agent-based simulation of consumer purchase behaviour based on quality,price and promotion

ABSTRACT

This paper studies the influence factors in consumer purchase behaviour. First, through reading and analysing the related paper, the authors summarise a lot of influence factors. Second, combined with the theme of the study, experts and scholars discuss these influence factors and choose quality, price and promotion of commodity as the object of this paper. Third, this paper presents an agent-based model and simulation method on the consumer purchase behaviours based on quality, price and promotion of commodity. The utility function is used to describe the model, which is implemented under NetLogo simulation environment. The results show that the proposed model can analyse and predict the effects of different quality, price and promotion strategies by the emergence of consumer purchase behaviour.     

城镇化进程中政府的职能作用

城镇化的推进需要各级政府发挥主导作用.本文认为,政府的主导作用主要表现为城镇化确立发展理念,科学定位区域内产业分工与协作,加强监督管理,改革城建投融资体制,促进城镇可持续发展,着力营造和优化环境等.政府要通过发挥决策作用、服务作用、法治规范作用、宣传教育作用等实现对城镇化的推进.

会计稳健性根源探析

利益相关者之间的信息不对称是会计稳健性产生的根本原因。损失函数的不对称包括契约性的和非契约性的。遭受损失的契约方会向管理当局和非契约方寻求帮助以降低其损失,准则制定机构和法律制定机构会分别制定更加稳健的会计准则以及执行严格的法律法规,从而保证处于信息劣势方不发生损失或者降低损失程度。准则以及各项法律法规在一定程度上形成了外部公司治理机制,从而产生了会计稳健性。     

社会工作在基层治理专业化中的角色与功能

近年来,我国对居民社区建设的重视度不断提升,社区公共服务团队也在不断壮大,在国家政策的实施以及广大社区管理中,社区管理机构发挥着十分关键的作用。随着城乡居民生活水平的不断提升,传统的管理模式与基层治理手段已经落后,难以满足社区发展与民众生活的多元化以及专业化需求,因此,在社区治理中,融入专业性社会工作已经成为大势所趋。论文结合社会工作参与乡村振兴建设战略所进行的一系列工作,探究社会工作在基层治理专业化道路上扮演的角色,指出社会工作在基层治理专业化中的功能,阐明当前社区治理中的问题,探索促进基层社区治理可持续发展的道路。

Three Corrected Score Tests for Generalized Linear Models with Dispersion Covariates

We develop three corrected score tests for generalized linear models with dispersion covariates, thus generalizing the results of Cordeiro , Ferrari and Paula (1993) and Cribari-Neto and Ferrari (1995) . We present, in matrix notation, general formulae for the coefficients which define the corrected statistics. The formulae only require simple operations on matrices and can be used to obtain analytically closed-form corrections for score test statistics in a variety of special generalized linear models with dispersion covariates. They also have advantages for numerical purposes since our formulae are readily computable using a language supporting numerical linear algebra. Two examples, namely, iid sampling without covariates on the mean or dispersion parameter oand one-way classification models, are given. We also present some simulations where the three corrected tests perform better than the usual score test, the likelihood ratio test and its Bartlett corrected version. Finally, we present a numerical example for a data set discussed by Simonoff and Tsai (1994) .
