The challenge of introducing low-carbon industrial practices: Institutional entrepreneurship in the agri-food sector

Contemporary agricultural practices account for a significant share of greenhouse gas emissions. Inspired by the emergent literature on institutional entrepreneurship, we seek to explore mechanisms that affect an actor’s propensity to act in ways that imply suggesting and promoting emission-reducing practice changes. As influences originating outside the organizational field are assumed to constitute such mechanisms, the paper explores their role through a case study of a project run by a public agency. Unlike extant theory, results show that the agency’s propensity to act is not necessarily enhanced by extra-field influences but that such influences also limit the scope for suggesting change that challenges existing industrial practices.     

The effects of demand,competitive, and technological uncertainty on board monitoring and institutional ownership of IPO firms

This paper considers industry-specific contingencies that may account for some of the inter-firm heterogeneity in the deployment of specific corporate governance mechanisms in IPO firms. We examine how differences in demand, competitive, and technological uncertainty in the industry influence the levels of IPO firm monitoring by board outsiders and institutional investors. We test our theory using a sample of U.S. firms that completed an IPO in 24 manufacturing industries. The results indicate that industry uncertainty is, indeed, significantly related to the use of corporate governance mechanisms. In particular, the empirical results indicate that industry effects on IPO firm board monitoring and institutional investor ownership are the strongest and most consistent for demand uncertainty and competitive uncertainty.

最终控制人性质、两权分离度与机构投资者持股——兼论不同类型机构投资者的差异

上市公司所有权与控制权的严重分离会影响其公司价值,进而会影响投资者的投资决策.本文以2004-2007年我国A股上市公司为研究样本,考察了上市公司两权分离状况对机构投资者总体和各类机构投资者持股决策的影响.研究发现,最终控制人所有权比例越高,两权分离度越小时,机构投资者(主要是证券投资基金)持股比例越高;而且两权分离度指标对机构投资者持股决策的影响在最终控制人为非国有性质的企业中表现更为明显.本文的研究结论表明.我国机构投资者总体上能够做到自我利益保护,在投资者保护方面发挥积极的作用,但是这种作用的发挥在各个类型机构投资者中存在显著差异.     

The lean improvement of the chemical emissions of motor vehicles based on preference ranking: A PROMETHEE uncertainty analysis

The motor vehicle has provided mobility and individual freedom for millions of people. However, vehicles embody the dilemma of contemporary industrialisation in that the environmental costs of automobility are equally large. This non-country specific study undertakes a PROMETHEE-based preference ranking of a small set of motor vehicles based on constituents of their exhaust emissions. As a model of an interested party's preference ranking of the motor vehicles, the subsequent uncertainty (sensitivity) analysis considered here, relates to what minimal (lean) changes would be necessary to a vehicle's emissions so that their preference ranking is improved. For a particular manufacturer, it can identify the necessary engineering performance modifications to be made to improve their perceived consumer based ranking. This is compounded by a further consideration of different levels of importance conferred on the criteria (vehicle emissions) and analogous analyses undertaken. The visual elucidation of the results rankings and changes to criteria values, offers a clear presentation of the findings to the interested parties.     

Green Purchasing by MNC Subsidiaries: The Role of Local Tailoring in the Presence of Institutional Duality

To examine the essential determinants of green purchasing by multinational corporations’ (MNC) subsidiaries, this study takes institutional theory as a foundation and focuses on the institutional duality associated with localization and globalization. Specifically, we develop a model to explain subsidiaries’ green purchasing and empirically test the model with data from 141 purchasing managers and senior purchasing staff members from subsidiaries in 39 countries. Our results suggest that pressures from headquarters and the local environment do not affect subsidiaries’ green purchasing directly; rather, they exert indirect influences through local tailoring. This study contributes to extant literature by revealing the significance of local tailoring in an MNC context. In addition, our findings offer several implications for practice by providing a roadmap for disseminating green purchasing across the subsidiaries of an MNC, as well as highlighting the importance of both clear communication about the benefits of green purchasing and internal audits.     

治理环境、政府控制和控制权定价——基于中国证券市场的实证研究

本文以我国上市公司2001-2004年间的经验数据为样本,实证分析了治理环境、政府控制对控制权交易定价的影响。研究发现,较好的治理环境会降低控制权的交易价格;对政府控制企业的控制权定价显著高于非政府控制的企业;股权制衡程度越高,对控制权的支付价格越低。进一步研究还表明,治理环境对控制权定价的负向作用在政府控制的企业中更为显著、影响更大。本文对理解转型经济中制度环境对公司治理的影响提供了有益视角。     

制度环境、公司治理对企业竞争优势的影响研究——基于中国上市公司的经验证据

如何通过外部制度和内部制度的安排延续企业的竞争优势,是制度变迁背景下中国企业面临的核心问题.本文以2002年-2005年的中国上市公司为样本,基于国内地区差距,实证分析了制度环境和公司治理时企业竞争优势的影响.回归结果发现,政府支持市场化程度、经济法律环境水平、股权集中度、股权竞争度、董事会独立性、专业委员会设置程度以及股东参与决策程度与企业竞争优势显著正相关.研究结果表明,好的制度环境与有效的公司治理能提高企业的竞争优势;企业持续竞争优势的源泉应包含以政府为主体的宏观层次的制度竞争和以企业为主体的微观层次的公司治理竞争.     

企业信息披露中的模仿行为研究——基于制度理论的分析

本文在制度理论的分析框架下,研究合法性压力和不确定性条件下企业信息披露中的模仿行为及由此导致的制度同形现象.本文以2006-2010年我国重污染行业上市公司年报中的环境信息披露为研究对象,发现企业环境信息披露存在同形性和模仿行为,且属于模仿其它企业平均水平的频率模仿,而不是模仿领先者.本文将已有的信息披露研究从经济学分析的视角向经济社会学进行拓展,丰富了对信息披露过程中决策者认知过程和制度化过程的认识,同时也透过信息披露中的模仿行为从更加微观的层面为制度化过程中的趋同现象提供了新的证据.     

The Governance of Voluntary Work in the Public Sector: Institutional Differences and Invariant Traits

In response to fiscal constraint and the introduction of quasi-market mechanisms into the public sector, in public policy there appears to be the acceptance of the increased use of voluntary labour in the delivery of public services. Traditional forms of governance have tended to ignore the use of voluntary labour in the public sector. The paper builds on an earlier (Hellshorm and Collins, 1999) model of concurrence between voluntary and municipal labour, by focusing onthe demand side of voluntary work. Our exploratory study uses this model to analyse two municipal organisations' mix of voluntary and municipal labour, one Italian and the other a Swedish context.The research method used to collect empirical data was semi-structured interviews of local government employees within the two sites. Thisis linked with an analysis of the institutional context of the two municipalities to inform and test the proposed model of demand for volunteer labour in local government. Resource scarcity, presence of agency for voluntary work, type of production and state rules and norm are used to analyse the institutional invariant traits. The study concludes that traditional institutional theory has ignored voluntary activities. Our case studies of actual practice indicate that different state norms and ruleson citizen rights and equal opportunities are stronger influential factors than the resources situation, in determining the demand for voluntary activities in municipalities.

Changes in mental well-being, blood pressure and total cholesterol levels during workplace reorganization: the impact of uncertainty

The aim of this study was to investigate the effects of uncertainty caused by large-scale workplace reorganization, on psychological well-being, blood pressure and total cholesterol levels. Employees (98 women and 86 men) were assessed four times, at approximately 6-monthly intervals, twice before and twice after reorganization. Self-reported psychological well-being was at its lowest level shortly prior to reorganization, as predicted. Greater self-reported uncertainty about one's own future occupational situation was associated with a bigger reduction in mental well-being before reorganization, as was role ambiguity after reorganization. Systolic blood pressure was elevated over initial levels just prior to reorganization, and shortly after reorganization, but at the final assessment was not significantly different from initial levels. A bigger increase in systolic blood pressure was seen in those reporting greater future job uncertainty before reorganization, and in those who started a new job or who reported greater role ambiguity after reorganization. Diastolic blood pressure was also significantly elevated over initial levels just before reorganization, but this effect became nonsignificant once changes in body mass index were statistically controlled. Total cholesterol also reached its highest level just prior to reorganization, but this effect was not significant. It is concluded that workplace reorganization caused significant increases in distress and in systolic blood pressure and that uncertainty contributed to these effects.

Share,like, twitter,and connect: Ecological momentary assessment to examine the relationship between non-work social media use at work and work engagement

Non-work social media use at work has seen a dramatic increase in the last decade and is commonly deemed counterproductive work behaviour. However, we examined whether it may also serve as a micro-break and improve work engagement. We used ecological momentary assessment across 1 working day with up to 10 hourly measurements in 334 white-collar workers to measure non-work social media use and work engagement, resulting in 2235 hourly measurements. Multilevel modelling demonstrated that non-work social media use was associated with lower levels of work engagement between persons. Within persons, non-work social media use was also associated with lower concurrent work engagement. However, non-work social media use was related to higher levels of work engagement 1 hour later. While more extensive non-work social media use at work was generally associated with lower work engagement, our advanced study design revealed that the longer employees used social media for non-work purposes during 1 working hour, the more work engaged they were in the subsequent working hour, suggesting that employees turn to social media when energy levels are low and/or when they (temporarily) lose interest in their work. This behaviour may serve as a break, which in turn increases work engagement later during the day.     

Sustained work, fatigue, sleep loss and performance: A review of the issues

The physiological and psychological stressors associated with sustained work, fatigue, and sleep loss affect worker performance. This review describes findings relating to sustained work stresses commonly found in our advancing technological world. Researchers report decrements in sustained performance as a function of fatigue, especially during and following one or more nights of complete sleep loss, or longer periods of reduced or fragmented sleep. Sleep loss appears to result in reduced reaction time, decreased vigilance, perceptual and cognitive distortions, and changes in affect. Sleep loss and workload interact with circadian rhythms in producing their effects. These interactions are a major source of stress in work situations requiring sustained work in continuous operations and have implications for theoretical models of sustained perceptual and cognitive functioning.     

Women, men, VDU work and health: A questionnaire survey of British VDU operators

This paper presents the results of a questionnaire survey of male and female VDU operators distributed through Health & Safety at Work magazine. 3819 questionnaires were analysed using the SPSS computer program. 57% of the sample were female, 68% were under 35 years old and 73% were members of a trade union or staff association. The large number of male respondents meant that it was possible to compare work patterns, types of work and health effects for men and women. It appears that women are engaged in more repetitive and less varied tasks at the VDU and that they work longer hours and for longer periods without a break than men. The most frequently reported health problems were eyestrain, painful or stiff neck and shoulders, fatigue and irritated eyes. The incidence of symptoms was related to hours of work at the VDU. Women were more likely to report health effects than men. This difference remains when hours of work, type of work and hours worked without a break are taken into account. Ergonomically designed equipment such as adjustable chairs, lighting or keyboard did not have an obvious effect on the reporting of symptoms. It appeared that there is a complex interaction between the physical, ergonomic and psychosocial factors associated with new technology. All these factors need to be taken into account in further research into the health problems of VDU operators.     

Resilience metrics in the assessment of complex supply-chains performance operating under demand uncertainty

The design and planning of resilient supply chains is a major challenge due to the increasing complexity of these systems that operate in a global market and therefore are more exposed to disruptions. In the present work a design and planning model that integrates demand uncertainty is applied to five supply chain structures that are submitted to different types of disruptions. Disruptions are modelled in a probabilistic manner, resulting in the incorporation of two sources of uncertainty. Eleven indicators are considered to assess the supply chains’ resilience, which comprise network design, centralization and operational indicators. The goal is to provide managers what are expected operational impacts (measured by the operational indicators) by assessing the behavior of network and centralization indicators and their known resilience behaviors from the literature. A case study of a European supply chain is used to illustrate the methodology and a discussion on the results obtained is presented in order to conclude which main characteristics a manager should consider when designing and planning resilient supply chains.     

A descriptive study of some organizational-behavior dimensions at work in the Dominican Republic: implications for management development and training

Based in identity theory and the depletion hypothesis in the work-life literature, this study investigated dimensions of the meaning of work and work stress among mid-level managers in the United States, Brazil, and Korea. Findings include a high salience of work as a central life concern but a primacy of family involvement in each country. The importance of religious involvement, leisure activities, and community involvement was rated low. Intrinsic and extrinsic orientations to working were related to increased levels of work stress, but in each country the dimensions of work stress were associated with meaning of work aspects in different combinations and affected different demographic groups in different ways. The theoretical and practical implications of the findings imply the need for a differentiated understanding of the meaning of work dimensions in international settings and the awareness that increased levels of work stress can results from higher levels of work centrality and intrinsic and economic work orientations.
