The effects of perceived quality of organizationally provided meal service on employees’ job performance and mediating role of organizational identification

Contemporary managers are developing alternative ways to sustain their competitive advantages. Motivation-enhancing features such as high-quality meal service provided by organizations can be thought of as one of these methods. The effect of the perceived quality of meal service provided by organizations on the job performance of employees and the mediating role of organizational identification during this process is studied. Private security-sector employees working in Turkey (N?=?597) are being focused in this study. As a result of analyses (correlation and regression analyses, structural equation model), the authors find that the perceived quality of meal service provided by organizations improves employees’ job performance significantly and organizational identification has a partial mediating role on this association. The findings of this study will be of interest to key stakeholders such as public or private organizations, labor unions and the media.     

Statistical inference for α-series process with the inverse Gaussian distribution

Statistical inferences for the geometric process (GP) are derived when the distribution of the first occurrence time is assumed to be inverse Gaussian (IG). An α-series process, as a possible alternative to the GP, is introduced since the GP is sometimes inappropriate to apply some reliability and scheduling problems. In this study, statistical inference problem for the α-series process is considered where the distribution of first occurrence time is IG. The estimators of the parameters α, μ, and σ² are obtained by using the maximum likelihood (ML) method. Asymptotic distributions and consistency properties of the ML estimators are derived. In order to compare the efficiencies of the ML estimators with the widely used nonparametric modified moment (MM) estimators, Monte Carlo simulations are performed. The results showed that the ML estimators are more efficient than the MM estimators. Moreover, two real life datasets are given for application purposes.     

The effect of different data structures,sample sizes on model fit measures

In this study, our aim was to investigate the changes of different data structures and different sample sizes on the structural equation modeling and the influence of these factors on the model fit measures. Examining the created structural equation modeling under different data structures and sample sizes, the evaluation of model fit measures were performed with a simulation study. As a result of the simulation study, optimization and negative variance estimation problems have been encountered depending on the sample size and changing correlations. It was observed that these problems disappeared either by increasing the sample size or the correlations between the variables in factor. For upcoming studies, the choice of RMSEA and IFI model fit measures can be suggested in all sample sizes and the correlation values for data sets are ensured the multivariate normal distribution assumption.     

Mortality among elder abuse victims in rural Malaysia: A two-year population-based descriptive study

Our study aims at describing mortality among reported elder abuse experiences in rural Malaysia. This is a population-based cohort study with a multistage cluster sampling method. Older adults in Kuala Pilah (n = 1,927) were interviewed from November 2013 to May 2014. Mortality was traced after 2 years using the National Registration Department database. Overall, 139 (7.2%) respondents died. Fifteen (9.6%) abuse victims died compared to 124 (7.0%) not abused. Mortality was highest with financial abuse (13%), followed by psychological abuse (10.8%). There was a dose-response relationship between mortality and clustering of abuse: 7%, 7.7%, and 14.0% for no abuse, one type, and two types or more, respectively. Among abuse victims, 40% of deaths had ill-defined causes, 33% were respiratory-related, and 27% had cardiovascular and metabolic origin. Results suggest a link between abuse and mortality. Death proportions varied according to abuse subtypes and gender.     

风险社会背景下大学生的信仰危机

当今,世界正由工业社会向风险社会过渡,信仰危机是当代人类面临的全球性问题,信仰危机的出现要求我们关注信仰教育。受全球化的影响,中国也处于风险社会之中。大学生作为我国社会主义事业的接班人,其信仰状况直接关系到国家的前途和命运。本文首先阐述了信仰以及信仰危机的含义,然后分析了我国大学生当前存在的信仰危机及其产生的原因,最后对于解决我国大学生的信仰危机提出了几点建议。     

实施技术创新战略提高国企可持续发展能力

加强技术创新对实施国家可持续发展战略,提高企业可持续发展能力至关重要.技术创新对国企的振兴与发展、企业市场竞争力的提高、产业结构调整下企业经营方式转变发挥着重要作用.要实现国企效益的普遍提高,必须克服企业技术创新系统中存在的技术创新激励机制弱化、科技与经济脱节问题,使企业成为技术创新主体,以促进企业实施可持续发展的技术创新战略.     

情绪的基本结构:争论、应用及其前瞻

情绪是一种复杂的心理现象。关于情绪的结构,主要有情绪分类与情绪维度两大理论解释取向。分类取向认为情绪由几种相对独立的基本情绪及在此基础上形成的复合情绪构成。维度取向则认为各类情绪之间彼此相关,应抓住情绪的主要维度进行结构性阐释,并以几种环形结构模型为代表。一些情绪理论模型尝试整合这两大解释取向。基于两种情绪结构理论,心理学家们开发过多种情绪量表和情绪诱导材料,而最近出现的几种(网络)情绪感知工具值得关注,互联网将在未来的情绪研究和实际应用中发挥重要作用。     

Bayesian unit-root tests for Stochastic Volatility models

In this article, we consider Bayesian inference procedures to test for a unit root in Stochastic Volatility (SV) models. Unit-root tests for the persistence parameter of the SV models, based on the Bayes Factor (BF), have been recently introduced in the literature. In contrast, we propose a flexible class of priors that is non-informative over the entire support of the persistence parameter (including the non-stationarity region). In addition, we show that our model fitting procedure is computationally efficient (using the software WinBUGS). Finally, we show that our proposed test procedures have good frequentist properties in terms of achieving high statistical power, while maintaining low total error rates. We illustrate the above features of our method by extensive simulation studies, followed by an application to a real data set on exchange rates.     

Ambivalent sexism and attitudes toward women who engage in premarital sex in Turkey

This study examined the relationship of ambivalent sexism, political conservatism, demographic variables (age, education, and gender), and prior sexual experience to Turkish men's and women's attitudes toward women who engage in premarital sex. Participants included 124 Turkish undergraduate students and 60 nonstudent Turkish adults. Benevolent but not hostile sexism uniquely predicted more negative views of women who engage in premarital sex once other variables were controlled. Regression analyses demonstrated that for both men and women, older, more politically conservative and less sexually experienced respondents and more educated men (but not women) respondents were more likely to disapprove of women who engage in premarital sex. Similarly, regression analysis revealed that men who were older, politically conservative, and less sexually experienced expressed stronger preferences for marrying a virgin. Both hostile and benevolent sexism predicted men's preference for marrying a virgin after all other variables were controlled.     

论萨特的自由观及其历史局限

自由是萨特最为关注的哲学问题。萨特宣扬的自由观的理论前提就是“存在先于本质”这一哲学命题。而颇具操作性品格的核心观点则是“自由选择论”。这是一种主观唯心主义的自由观 ,因而注定是孤独的 ,不融于世的。站在新世纪的起点上 ,运用马克思主义哲学方法论对这一思想遗产进行审视和扬弃 ,是非常必要的。
