私营企业主的劳动属性再认识

私营企业主的劳动,从本质上看包含着大量的创新劳动,从分工上看绝大部分是管理劳动和科技劳动。他们的劳动具有高脑力劳动强度、高劳动风险压力、超常劳动时间和劳动的高增值性等特点。私营企业主的劳动理应受到尊重和保护,因为它是在社会主义制度下合法进行的,是有中国特色社会主义总劳动的一部分,并有力地促进了有中国特色社会主义的发展。在私营企业主的收入中非劳动收入的比重有下降的趋势。     

Ecocultural Attributes: Evaluating Ecological Degradation in Terms of Ecological Goods and Services Versus Subsistence and Tribal Values

It is becoming increasingly clear that scientists, managers, lawyers, public policymakers, and the public must decide how to value what is provided by, and is a consequence of, natural resources. While “Western” scientists have clear definitions for the goods and services that ecosystems provide, we contend that these categories do not encompass the full totality of the values provided by natural resources. Partly the confusion results from a limited view of natural resources derived from the need to monetize the value of ecosystems and their component parts. Partly it derives from the “Western” way of separating natural resources from cultural resources or values, and partly it derives from the false dichotomy of assuming that ecosystems are natural, and anything constructed by man is not natural. In this article, we explore the previous assumptions, and suggest that because cultural resources often derive from, and indeed require, intact and unspoiled natural ecosystems or settings, that these values are rightly part of natural resources. The distinction is not trivial because of the current emphasis on cleaning up chemically and radiologically contaminated sites, on restoration of damaged ecosystems, on natural resource damage assessments, and on long‐term stewardship goals. All of these processes depend upon defining natural resources appropriately. Several laws, regulations, and protocols depend upon natural resource trustees to protect natural resources on trust lands, which could lead to the circular definition that natural resources are those resources that the trustees feel they are responsible for. Where subsistence or tribal peoples are involved, the definition of natural resources should be broadened to include those ecocultural attributes that are dependent upon, and have incorporated, natural resources. For example, a traditional hunting and fishing ground is less valued by subsistence peoples if it is despoiled by contamination or physical ecosystem degradation; an Indian sacred ground is tarnished if the surrounding natural environment is degraded; a traditional homeland is less valued if the land itself is contaminated. Our argument is that intact natural resources are essential elements of many cultural resources, and this aspect requires and demands adequate consideration (and may therefore require compensation).     

The relationship between presenteeism and job satisfaction: A mediated moderation model using work engagement and perceived organizational support

Research on presenteeism has largely focused on its prevalence, determinants and consequences on the health of both employees and organizations. To date, few studies have examined the influence of presenteeism on workers’ attitudinal and motivational responses. Based on the Effort–Recovery Theory, this study evaluates the mediating effect of work engagement in the relationship between presenteeism and job satisfaction. Building on previous work, this study also proposes to consider perceived organizational support as a moderator of the work engagement–job satisfaction relationship. Presented in the form of a mediated moderation model, the results of bootstrapped regression analyses show three main results. First, presenteeism is negatively associated with work engagement and job satisfaction. Secondly, work engagement is one of the factors through which presenteeism influences job satisfaction. Thirdly, perceived organizational support moderates the association between work engagement and job satisfaction so that, at a low level of work engagement, feeling supported by the organization makes a difference on job satisfaction. Overall, this research is part of the limited number of studies that have focused on the interplay existing between presenteeism and its consequences in terms of job attitudes.

人格特质、组织承诺与离职意图关系的实证研究

通过对中国联通安徽分公司131名雇员进行实证分析,考察了个人属性、内外控型人格特质、组织承诺与雇员离职意图的关系。结果发现组织承诺、内外控人格特质对离职意图有显著影响,个人属性中除婚否外,其他属性对离职意图也有显著影响。推测组织承诺将极有可能是个人属性与离职意图间的中介变量,并且对内外控人格特质与离职意图之间的关系具有调节作用。     

组织职业生涯管理与工作卷入关系的研究

本研究以龙立荣开发的组织职业生涯管理问卷的简缩版和修订过的Kanungo的工作卷入问卷为测量工具,对多家企业的员工进行了调查。统计分析结果显示:组织职业生涯管理与员工的工作卷入之间存在显著的正相关关系,组织职业生涯管理中的各个维度与员工工作卷入的相关关系均达到了显著性水平,其中与员工工作卷入相关性最大的是“晋升公平”,相关性最小的是“注重培训”。此研究证明了组织职业生涯管理的必要性。     

级别不低于方法及其发展评述

级别不低于方法是一类解决多属性决策问题的重要方法.相对于其他方法力图建立可行方案集上的完全序.级别不低于方法所构建的是一种较弱的二元关系--级别不低于关系,它所要求的条件较弱,而得到的结果更为可靠.是近年来研究最为活跃、应用十分广泛的方法之一.本文将级别不低于方法划分为ELECTRE、PROMETHEE和PCCA等三大类分别进行了归纳和总结;介绍了近年来级别不低于方法的新发展,对级别不低于方法的公理化.不确定信息下的级别不低于方法以及多属性决策的敏感性分析和鲁棒性分析等问题给出了一些有意义的讨论.特别是对鲁棒性的定义和分析方法提出了一务切实可行的思路.

Job loss and family adjustments in work and schooling during the Mexican peso crisis

We use individual data from a panel of families during the depth of the peso crisis in Mexico to investigate whether the transition of the male household head from employment into unemployment affects the labor force participation of his spouse and children. We find that significant added-worker effects are in operation especially for adult females (wives), but no evidence that the labor force participation, the school attendance, and the likelihood of advancing to the next school grade of teenage males are influenced by the event of unemployment of the household head. The head's unemployment is significantly associated with a higher probability that teenage females do not attend school. However, lower attendance does not appear to impede their advancement to the next grade.

Self-Stigma of seeking help and job burnout in mental health care providers: the comparative study of Lithuanian and the USA samples

This study aimed to explore the correlation between job burnout and self-stigma of seeking help among nonmedical mental health care providers (psychologists, social workers, and counselors) in two countries – Lithuania and the US. The study included 234 professionals (111 social workers and 123 psychologists) from Lithuania and 93 professionals (33 counselors, 23 social workers, and 37 psychologists) from the US on a voluntary basis (93% females, mean age – 39.81?years). They completed a self-reported questionnaire with the Self-Stigma of Seeking Help Scale (SSOSH) and the Maslach Burnout Inventory-General Survey (MBI-GS). The results revealed a statistically significant positive correlation between self-stigmatization and burnout in the Lithuanian sample, but only weak positive correlation between depersonalization and self-stigma of seeking help in the US sample. The relationship between the self-stigma of seeking help and burnout was stronger in the Lithuanian sample of professionals when compared to their colleagues in the US.
