通用性指标偏好及其实验研究——平衡计分卡在多部门企业中的应用

文章分析了通用性指标偏好产生的原因、影响和解决途径,并通过实验研究,考察了中国实验者在平衡计分卡应用中是否也存在通用性指标偏好,以及集体决策方式对通用性偏好程度的影响。决策者组成的多元化,是集体决策发挥作用的重要因素,这一结论对于部门平衡计分卡在现实中的应用和企业绩效评价实践具有启示作用。     

学前儿童性别教育的研究现状及其启示

学前儿童性别教育的有关研究表明,社会上还存在着根深蒂固的性别歧视和性别偏见,身处特定环境中的学前教育教师以及图画书、教学媒体等仍然带有较强的性别歧视和性别偏见等性别刻板印记。为此,国家需要在学前儿童性别教育研究的基础上重视学前教育阶段的性别平等教育,制定相关的政策,建立性别教育的终身教育体系,构建教师性别平等教育的培训网络平台,以现代性别教育理念为指导,基于对儿童生理差异的尊重,设计出适合学前儿童身心发展特点的性别教育课程,全面有效地实施性别平等教育。     

An improved alternative estimation procedure for current population mean in presence of positively and negatively correlated auxiliary variables in two-occasion rotation patterns

Abstract

The present study confirms the influential role of a positively and a negatively correlated auxiliary variables in enhancing the precision of estimates of current population mean in two occasion rotation (successive) sampling. Exponential-type estimators of current population mean have been proposed for three different situations: (i) the information on a positively correlated auxiliary variable is readily available on both occasions (ii) the information on a negatively correlated auxiliary variable is readily available on both occasions and (iii) the information on both positively and negatively correlated auxiliary variables are readily available on both the occasions. The characteristics of the proposed estimators have been explored and their efficacious performances are compared with the natural and recent contemporary estimators. Optimum replacement strategies of the proposed estimation procedures have been formulated. Simulation and empirical studies are carried out to justify the proposition of the proposed estimators and appropriate recommendations have been put forward to the survey practitioners.     

Improved Estimates and Confidence Intervals for Regenerative Simulation

In regenerative simulation, one frequently requires an estimate or a confidence interval for the ratio of the means of the two components of a certain bivariate random quantity. Estimation of this ratio has been studied by many authors and most recently by Asmussen and Rydén(2010 Asmussen, S., Rydén, T. (2010). A note on skewness in regenerative simulation. Communications in Statistics—Simulation and Computation 40: 45–57.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Here, we propose an estimate that performs better than the best of the known estimates. Our estimate is also lot simpler than the best known estimate.     

“Newsworthy” Victims?

More than 500 Aboriginal women have gone missing or been murdered in Canada since the 1980s yet press attention to this violence is relatively minimal. This paper compares local press coverage of matched cases: three missing/murdered Aboriginal women from Saskatchewan and three missing/murdered White women from Ontario. Quantitative and qualitative content analyses indicate stark disparities in the amount and content of coverage between groups. The Aboriginal women received three and a half times less coverage; their articles were shorter and less likely to appear on the front page. Depictions of the Aboriginal women were also more detached in tone and scant in detail in contrast to the more intimate portraits of the White women. Drawing on feminist media studies and theories of intersectionality, this paper argues that the simultaneous devaluation of Aboriginal womanhood and idealization of middle-class White womanhood contributes to broader systemic inequalities which re/produce racism, sexism, classism, and colonialism. This paper raises concerns about the broader implications of the relative invisibility of missing/murdered Aboriginal women in the press, and their symbolic annihilation from the Canadian social landscape.     

Measuring the impact of prices on inequality: With applications to Thailand and Korea

This paper develops a new methodology to compute social cost of living indices. These indices indicate whether or not price changes have a favourable (or unfavourable) impact on the welfare of the poor. The indices are derived on the basis of two alternative classes of social welfare functions. The methodology developed in the paper is applied to compute social cost of living indices for Thailand and Korea. The empirical results show that changes in prices have generally affected the poor more adversely than the non-poor.     

损失厌恶、后悔厌恶与沉没成本效应的关联性分析

以往研究认为沉没成本效应的产生与损失厌恶和后悔厌恶相关,但对其相互关系的探讨较少考虑货币性沉没成本和非货币性沉没成本的不同影响.文章选取证券监管者和证券市场投资者作为被试对象,通过有情境因素的调查问卷对损失厌恶、后悔厌恶与沉没成本效应之间的关联性进行验证.实证结果发现,与证券市场投资者相比,证券监管者的损失厌恶倾向要显著更低,而二者的后悔厌恶和沉没成本效应则无显著差异;证券监管者的数据结果表明,后悔厌恶与沉没成本效应之间存在显著的相关性,而损失厌恶与沉没成本效应之间不存在显著的相关性;相比之下,证券市场投资者的数据结果则表明,损失厌恶与沉没成本之间存在显著的相关性,而后悔厌恶与沉没成本之间则不存在显著的相关性.     

证券分析师性别、盈余预测偏差与纠偏能力

证券分析师个人特征是其能力的重要表征.文章选取2007-2014年我国资本市场相关数据,研究了证券分析师的性别对盈余预测偏差的影响,以及盈余预测偏差的时间序列特征,实证结果显示:第一,整体上男性分析师的盈余预测偏差大于女性分析师;第二,男性分析师对于盈余预测偏差的纠正能力高于女性分析师;第三,随着对公司跟踪时间的增加,男性分析师的盈余预测偏差下降速度更快.研究结果说明,对于分析师跟踪时间较短的公司,女性分析师的盈余预测偏差较小,而对于受分析师长期跟踪的公司,男性分析师的盈余预测结果更准确.研究结论对投资者依据分析师性别判定其盈利预测准确性具有重要意义.     

The Inability of Self-affirmations to Decrease Defensive Bias Toward an Alcohol-Related Risk Message Among High-Risk College Students

Abstract

Objective: To examine the efficacy of a self-affirmation task in deterring college alcohol misuse and the importance of preexisting beliefs in predicting subsequent behavior change. Participants: Heavy-drinking undergraduates (N = 110) participated during the 2011–2012 academic year. Methods: Participants were randomized to complete an affirmation or control task before reading an alcohol risk message. Alcohol-related beliefs and behaviors were assessed. Participants completed a 2-week online follow-up assessing alcohol-related behaviors. Results: Both groups reported increased perceived problem importance, but neither group displayed changes in personal risk. Follow-up assessment revealed similar, significant declines in peak consumption in both groups, with no significant between-group differences. Preexisting beliefs accounted for 5% to 10% of variance in drinking outcomes. Conclusions: An affirmation task does not seem to decrease defensive processing or alter high-risk drinking behaviors among college students and should not be utilized in lieu of more effective strategies.     

Domestic Abuse Assessment in Child Custody Disputes: Beware the Domestic Violence Research Paradigm

ABSTRACT

In some states, custody assessors are now required to become familiar with the dynamics of prevalence of domestic abuse since the presence of one or more abusive parents in the house has an impact on the “best interests of the child.” The domestic abuse literature is misleading in setting a framework for abuse incidence and threat source for children. Males are represented as primary perpetrators of physical abuse although data from meta-analytic studies show otherwise. Indirect aggression is scarcely mentioned in the literature, although prevalent in research on aggression. Physical violence directed towards children is actually more likely to be mother-perpetrated. Child safety may be compromised if attention is focused solely on the possibility of abuse from a male perpetrator.
