基于社会交换理论,在中国情境下探讨了不同类型的幽默型领导对员工创造力的影响,以及领导-成员交换的中介作用,权力距离取向与上下级共事时间的调节作用.通过对334名员工问卷调查数据进行多层回归分析,结果表明:(1)不同类型的幽默型领导对员工创造力的影响效果不同.其中,亲和幽默型领导显著正向影响员工创造力,攻击幽默型领导显著负向影响员工创造力;(2)以上两种幽默型领导均能通过领导-成员交换影响员工创造力;(3)权力距离取向作为一种社会交换的文化背景,缓和了攻击幽默型领导与领导-成员交换之间的负向关系;(4)上下级共事时间作为一种社会交换的时机,既能减弱亲和幽默型领导与领导-成员交换、员工创造力的正向关系,又能减弱攻击型幽默与领导-成员交换、员工创造力的负向关系.  相似文献

城市建成环境对人类健康的影响越来越受到关注,老年人在中国已经构成重要的群体,建成环境不仅仅对他们自身健康产生影响,也会对他们子女的生活和工作产生冲击,带来社会问题。以重庆市为例,选择了老年人这一群体,通过问卷调查获取数据,建立有序多分类Logsitic模型,研究建成环境如何通过影响老年人的休闲健身活动(尤指步行运动)从而影响其身体质量指数(BMI)。结果表明,除了年龄、是否偏爱高热量饮食外,居住地是否有休闲运动场所、居住地到休闲运动场所的距离与因变量老年人BMI指数等级存在显著联系。其中,居住地距离休闲运动场所1000m以内是最佳范围,在这一范围内休闲运动场所对老年人身体质量指数等级的影响显著并且随着距离增加而衰减。最后根据研究结论提出建成环境优化建议。  相似文献

Assessing corporate environmental performance (CEP) that is both comprehensive and consistent with sustainable development both for society and companies, while at the same time taking heed of the facts and interests of each stakeholder, is not a simple feat. Due to the multidimensional character of the sustainability concept, several questions must be considered in the evaluation process: (i) the qualitative nature of indicators and the complexity of developing a synthetic index; (ii) the difficulty of choosing properly statistical techniques for aggregation and (iii) the difficulty of introducing stakeholders’ preferences in the assessment models. This paper is an attempt to address this challenge by developing a framework for the assessment of CEP, based on the application of a fuzzy multi‐criterion decision‐making (MCDM) method. To achieve positive scores in a CEP assessment, an organization should be strategically committed and engage in environmental management and governance structures that are translated into good results in terms of both engagement and operational performance. Unless such premises are explicitly incorporated into the assessment criteria, the results would reveal that the CEP measurement could not be brought into a line with an earnest ambition of achieving true sustainable development.

There are an increasing number of companies in the mining and metals sector disclosing environmental sustainability information in their annual reports, sustainability reports and corporate internet web pages. However, there is ongoing debate about the relationship between the quantity and the quality of environmental disclosure. That is, does an increase in number equate to an increase in quality? This study investigates the relationship between the quantity and the quality of environmental disclosure reports. Using content analysis, we examine the environmental disclosure of 55 Australian mining and metal companies which are listed among the Australian Securities Exchange's (ASX) Top 100 mining and metal sector companies. We find that the size of firms influences both the quantity and the quality of corporate environmental disclosure. That is, we find that market capitalization is positively and significantly correlated to the quantity (number of words) and the quality of disclosure. We also confirm that there is a very highly significant, positive correlation between quantity (number of words) and quality of environmental disclosure. In order to investigate any differences between the top performing group and the bottom performing group in terms of environmental disclosure quality, further analysis also confirms that there is a positive relationship between the quantity and the quality of environmental disclosure.

This study develops a moderation model to examine the role of a proactive environmental strategy on eco‐innovation. Drawing upon the perspectives of contingency theory, this study argues that the impacts of sustainability strategy on eco‐innovation depend on market demand, innovation intensity and government subsidy. The sample used to test the hypotheses is obtained from the Community Innovation Survey in Taiwan. A total of 2955 manufacturing firms are included in the final sample. A logit moderating regression is adopted to analyze the models. The results reveal that market demand and government subsidy positively moderate the relationship between environmental strategy and eco‐innovation. Specifically, firms are more likely to adopt a proactive environmental strategy to improve eco‐innovation under high levels of market demand and government subsidy. Furthermore, the results indicate that innovation intensity affects the effect of environmental strategy on eco‐innovation, but the direction of the influence varies with different categories of eco‐innovation.

Building on social movement theory, this study assesses the influence of social media activism on the stock market performance of targeted firms. We focus on information published on Twitter by two critical stakeholders: consumer associations and trade unions. To the extent that social media represent a valid medium to mobilize stakeholders' activism, protests on Twitter may damage firm reputation, leading to capital market reactions. Using a corpus of over 1.5 million tweets referring to Spanish listed banks, we study the impact of activism by looking at targeted firms' abnormal variations in price and trading volume. Our findings suggest that the Twitter activism of key stakeholders has a significant impact on investors' decisions. Further, our empirical analyses indicate that the mechanisms affecting investors' behavior differ depending on the characteristics of the stakeholder group. Hence, this study contributes to understanding how social movements influence corporate behavior via social media. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment  相似文献

Human resource (HR) managers’ commitment to their occupation (HR) leads to the proper delivery and implementation of HR practices and, therefore, is deemed as a critical factor for the success of HR practices. Based on sociocognitive, human capital, and signaling theories, this study examines: (a) HR managers’ own and their chief HR officer's (CHRO) HR‐specific human capital as antecedents of their commitment to HR, and (b) the mediating mechanism through which the CHRO’s HR‐specific human capital positively influences HR managers’ commitment to HR. Based on 146 HR managers from 146 organizations in South Korea, the findings of the current study suggest that HR managers with higher levels of HR‐specific human capital and those working with CHROs with higher levels of HR‐specific human capital tend to have higher levels of commitment to HR. In addition, CHROs with higher levels of HR‐specific human capital positively influence HR managers’ commitment to HR by signaling to them that HR and its function are valued and cared about by their organizations. Theoretical and practical implications of this study are discussed along with study limitations and further research directions. © 2015 Wiley Periodicals, Inc.  相似文献

“Worthless,” “money burning,” or “black holes” is how media and professionals describe compliance practices today. Practitioners are unenthusiastic about control systems, codes of conducts, and systems for compliance management that are increasing in volume but not in effectiveness. In order to help practitioners clarify what actually makes employees comply with their compliance program, this study examines intrinsic and extrinsic motivators of 119 employees from procurement and sales. We contribute to the existing motivation literature, testing the self‐determination theory in low and high hierarchical levels. Our findings show that intrinsic motivators are more strongly and positively related to compliance intention on higher hierarchical levels than the lower ones. However, employees from higher hierarchies show overall less compliance intention than employees from lower hierarchies. © 2015 The Authors.

In the era of a graying workforce, individuals and their employers are concerned with the impact of the graying workforce on the level of engagement at work. Contrary to the myths about older workers being less engaged, statistics have shown that the level of engagement is higher as people age. Within the broad framework of conservation of resources theory in the area of work engagement, the current study aims to clarify how older workers are more engaged at work than younger workers. Building upon socioemotional selectivity theory and continuity theory from a life‐span perspective, we explain how individuals gain more resources as they age, including the abilities to regulate emotion and to maintain a career identity. We argue that this positive relationship between age and resources explains why older people have high levels of work engagement. We tested our predictions with a sample of 613 workers in the United States. The study demonstrates that well‐regulated emotion and strong commitment to career mediate the positive relationship between age and work engagement simultaneously. These findings contribute to the understanding of an aging workforce's engagement in the workplace. © 2016 Wiley Periodicals, Inc.  相似文献
