中日近世商品经济观及其现代价值——以石门心学和浙东学派为中心

日本江户时代的"石门心学"与中国宋代浙东学派的商品经济观,共同具有典型的近世特征,也都对后世有很大影响。但由于社会结构、制度基础与思想文化等诸多差异,在两国近代化的历史转型与社会发展过程中,二者所发挥的作用也大有不同。对中日近世商品经济观进行系统性的比较研究,不仅有利于弥补世界经济学说史迄今大抵无东亚等缺憾,而且可以提供观察传统经济观之现代价值的一个新视角。

丈夫外出务工对农村留守妇女的心理影响分析

通过以社区为基础的微观社会学研究视角,可分析农村男性外出务工对留守妇女的心理影响及其原因。大多数农村留守妇女有较大的生活压力感;两地分居的婚姻状态也导致她们处于性压抑状态,且具有强烈的孤单感;她们的不良情绪如烦躁、压抑等在丈夫外出务工后明显加剧;不安全生活事件、性骚扰以及对丈夫的担心导致她们的安全感很低。这种丈夫流动、妻子留守的家庭策略使得农村婚姻和家庭的情感满足功能大大削弱。为了缓解留守妇女承受的负面心理影响,在外务工的丈夫应尽量为妻子提供情感支持和慰藉;农村社区应组织留守妇女互助小组,丰富社区文化生活,健全社区治安防范体系。     

基于Johansen程序的协整参数自举分析

 考虑静态和动态两类数据生成过程,利用蒙特卡罗模拟方法,从估计偏差、实际检验水平和检验功效三个方面对基于Johansen程序的长期参数渐近分析和自举分析进行全面比较。结果表明,与渐近分析相比,自举分析可以减小实际检验水平对名义水平的偏差,但要以检验功效的降低为代价。严格意义上,自举分析是降低了“拒真”错误出现的概率,如果VAR（Vector Autoregression）模型能够很好地拟合数据,自举分析可能导致实际检验水平低于名义水平,此时应该慎用。使用Johansen程序估计协整参数时,容易出现异常估计值,因而不宜通过自举法修正估计偏差。     

Model-robust supersaturated and partially supersaturated designs

Supersaturated designs are an increasingly popular tool for screening factors in the presence of effect sparsity. The advantage of this class of designs over resolution III factorial designs or Plackett–Burman designs is that n, the number of runs, can be substantially smaller than the number of factors, m. A limitation associated with most supersaturated designs produced thus far is that the capability of these designs for estimating g active effects has not been discussed. In addition to exploring this capability, we develop a new class of model-robust supersaturated designs that, for a given n and m, maximizes the number g   of active effects that can be estimated simultaneously. The capabilities of model-robust supersaturated designs for model discrimination are assessed using a model-discrimination criterion, the subspace angle. Finally, we introduce the class of partially supersaturated designs, intended for use when we require a specific subset of _m1$m_1$ core factors to be estimable, and the sparsity of effects principle applies to the remaining (m-_m1$m-m_1$) factors.     

Estimating parameters in extended growth curve models with special covariance structures

In this paper the estimation of the unknown parameters is considered in standard growth curve model with special covariance structures. Based on the unbiased estimating equations, some new methods are proposed. The resulting estimators can be expressed in explicit forms. The statistical properties of the proposed estimators are investigated. Some simulation results are presented to compare the performance of the proposed estimator with that of the existing approaches. Finally, these methods are applied in general extended growth curve model with special covariance structures.     

Some state space models of hiv epidemic and its applications for the estimation of hiv infection and incubation

In this paper we have developed some state space models for the HIV epidemic for populations at risk for AIDS. By using these state space models, we have developed a general Bayesian procedure for estimating simultaneously the unknown parameters and the state variables. The unknown parameters include the immigration and recruitment rates, the death and retirement rates, the incidence of HIV infection ( and hence the HIV infection distribution ) and the incidence of HIV incubation ( and hence the HIV incubation distribution). The state variables are the numbers of susceptible people (S people), HIV-infected people (I people) and AIDS incidence over time. The basic approach is through multi-level Gibbs sampler combined with the weighted bootstrap method. We have applied the methods to the Swiss AIDS homosexual and IV drug data to estimate simultaneously the unknown parameters and the state variables. Our results show that in both populations, both the HIV infection and HIV incubation have multi-peaks indicating the mixture nature of these distributions. Our results have also shown that the estimates of the death and retirement rates for I people are greater than those of S people, suggesting that the infection by HIV may have increased the death and retirement rates of the individuals.     

The analysis of MX/M/1 queue with two-stage vacations policy

Abstract

In this article, we consider a batch arrival M^X/M/1 queue with two-stage vacations policy that comprises of single working vacation and multiple vacations, denoted by M^X/M/1/SWV?+?MV. Using the matrix analytic method, we derive the probability generating function (PGF) of the stationary system size and investigate the stochastic decomposition structure of stationary system size. Further, we obtain the Laplace–Stieltjes transform (LST) of stationary sojourn time of a customer by the first passage time analysis. At last, we illustrate the effects of various parameters on the performance measures numerically and graphically by some numerical examples.

医疗集团模式下廉洁文化建设联盟发展策略研究

为分析医疗集团成员单位廉洁文化建设现状及发展需求,对7家成员单位的廉政教育、廉政制度、廉政监督、廉洁文化建设效果、廉洁文化建设需求开展问卷调查,并采用模糊评价法对廉洁文化联盟建设现状进行评价。结果显示,7家集团成员单位廉洁文化建设现状模糊综合评价得分处于较高水平,但联盟中不同成员单位之间廉洁文化建设质量存在一定差异。廉洁文化建设任重道远,应基于各单位发展需求差异,促进集团成员单位廉洁文化建设标准化与特色化齐头并进。
