真实性偏好如何影响全球品牌中国元素产品的购买可能性?

在中国市场上,全球品牌本土化的现象越来越频繁.但在理论上,还少有研究分析中国消费者如何评价融入中国元素的全球品牌.为此,文章以认知—情感人格系统理论为框架,构建了包含真实性偏好、品牌本土象征价值、尊重品牌遗产和购买可能性的概念模型,试图探索其中的因果关系.实证研究表明,品牌本土象征价值认知—情感单元和尊重品牌遗产认知—情感单元均能提高购买可能性.真实性偏好高的消费者更容易通达品牌本土象征价值认知—情感单元和尊重品牌遗产认知—情感单元.尊重品牌遗产认知—情感单元有助于增强品牌本土象征价值认知—情感单元.文章不仅在理论上丰富了全球品牌相关研究,同时对实践也有战略指引.     

农村婚姻暴力受害因素的有效对称研究

立足农村家庭结构与中国特有的新型农村社会保障体系,以湖南某县级市的实证调查为依据,运用主成分分析、最小二乘回归分析和bootstrapping法,探究婚姻暴力受害因素对不同性别的解释力度。结果显示：农村女性受暴总体高于男性,家庭规模的扩大与家庭关系满意度的提升降低男性家暴的受害,社会支持网规模的扩大增加了两性遭受家暴的风险,“新农保”与“新农合”制度成为降低女性家暴受害的保护性因素,家庭功能衰弱导致家暴的情况没有出现,农村男性与女性家暴受害因素呈有限对称。     

桥塞坐封过程仿真模拟研究

桥塞作为井下封层技术的关键设备,由于它施工工序少、周期短、卡封位置准确而得到了广泛应用。针对设计的可钻式非金属桥塞坐封过程开展模拟研究,涉及弹塑性材料接触、超弹性材料接触和非金属材料动态断裂的非线性动力学问题,利用有限元法建立该桥塞全尺寸模型和所有部件之间的广义接触关系,通过有限元模拟动态坐封过程获得桥塞各部件运动变形特性、桥塞与套管之间的密封特性和动态坐封力等数据,该桥塞坐封完成时,坐封机构部件轴向位移110 mm,坐封力约45 kN。模拟坐封也为进一步优化该型桥塞的结构和评估坐封性能提供了理论依据,对该型桥塞的推广应用奠定了基础。     

Bayesian estimation and influence diagnostics of generalized partially linear mixed-effects models for longitudinal data

This paper develops a Bayesian approach to obtain the joint estimates of unknown parameters, nonparametric functions and random effects in generalized partially linear mixed models (GPLMMs), and presents three case deletion influence measures to identify influential observations based on the φ-divergence, Cook's posterior mean distance and Cook's posterior mode distance of parameters. Fisher's iterative scoring algorithm is developed to evaluate the posterior modes of parameters in GPLMMs. The first-order approximation to Cook's posterior mode distance is presented. The computationally feasible formulae for the φ-divergence diagnostic and Cook's posterior mean distance are given. Several simulation studies and an example are presented to illustrate our proposed methodologies.     

Diagnostics in elliptical regression models with stochastic restrictions applied to econometrics

We propose an influence diagnostic methodology for linear regression models with stochastic restrictions and errors following elliptically contoured distributions. We study how a perturbation may impact on the mixed estimation procedure of parameters in the model. Normal curvatures and slopes for assessing influence under usual schemes are derived, including perturbations of case-weight, response variable, and explanatory variable. Simulations are conducted to evaluate the performance of the proposed methodology. An example with real-world economy data is presented as an illustration.     

Goodness-of-fit tests of generalized linear mixed models for repeated ordinal responses

Categorical longitudinal data are frequently applied in a variety of fields, and are commonly fitted by generalized linear mixed models (GLMMs) and generalized estimating equations models. The cumulative logit is one of the useful link functions to deal with the problem involving repeated ordinal responses. To check the adequacy of the GLMMs with cumulative logit link function, two goodness-of-fit tests constructed by the unweighted sum of squared model residuals using numerical integration and bootstrap resampling technique are proposed. The empirical type I error rates and powers of the proposed tests are examined by simulation studies. The ordinal longitudinal studies are utilized to illustrate the application of the two proposed tests.     

我国金融控股公司立法必要性探析

金融控股公司作为我国金融“分业”体制下实现“混业经营”目的的一种组织创新模式,在我国的发展日益迅速,而我国立法空缺的现状却严重阻碍了其健康发展,也造成了极大的金融风险。文章利用历史分析、比较分析和法经济学的方法,通过对我国金融业历史发展演进的纵向考察,对世界金融控股公司普遍立法现状的横向比较以及金融控股公司作为一种经济组织形式与我国金融立法关系的分析,论证了我国金融控股公司立法的必要性。     

论作为武侠小说叙事元素的历史

历史作为武侠小说中的一种元素,从武侠小说的发展历程来看,并不是它必须具备的.历史元素在武侠小说中往往以历史细节的形式存在,而这个细节的真伪是无关紧要的.但历史在武侠小说中的另一种存在形式,即历史观,却具有非常重要的地位,它与文学的存在价值有关.     

Variable selection in elliptical linear mixed model

Variable selection in elliptical Linear Mixed Models (LMMs) with a shrinkage penalty function (SPF) is the main scope of this study. SPFs are applied for parameter estimation and variable selection simultaneously. The smoothly clipped absolute deviation penalty (SCAD) is one of the SPFs and it is adapted into the elliptical LMM in this study. The proposed idea is highly applicable to a variety of models which are set up with different distributions such as normal, student-t, Pearson VII, power exponential and so on. Simulation studies and real data example with one of the elliptical distributions show that if the variable selection is also a concern, it is worthwhile to carry on the variable selection and the parameter estimation simultaneously in the elliptical LMM.     

侵犯著作权行为的刑事法分析

侵犯著作权的行为在我国近年有愈演愈烈的趋势,并且产生了一些新的侵权行为。相形之下,现行刑法中的相关规定在打击侵犯著作权行为的实践中渐显滞后。综观我国侵犯著作权立法的历史沿革和现行刑法中有关侵犯著作权罪的犯罪构成,结合司法实践,要从扩展刑法对著作权的保护范围,取消犯罪主观案件中的非法营利目的,侧重于对被害人的实质补偿,修改罚金刑、增强其可操作性,确立对侵犯著作权犯罪以自诉为主、公诉为辅的犯罪追诉模式和充分保护著作权人的权益以及社会公共利益等方面,进一步完善我国侵犯著作权罪的相关规定。
