Reasons To Be Ethical: Self-Interest and Ethical Business

This paper examines the self-interested reasons that businesses can have for ethical behaviour. It distinguishes between economic and non-economic reasons and, among the latter, notes those connected with the self-esteem of managers. It offers a detailed typology of prudential reasons for ethical behaviour, laying particular stress on those to do with avoiding punishment by society for wrongdoing and, more particularly still, stresses the role of campaigning pressure groups within that particular category of reasons. It goes on to suggest that because of their occupation of the moral high ground, campaigning groups are well placed to damage the self-esteem of managers and that this is why those groups seem able to exert an influence that goes beyond their somewhat limited capacity to inflict economic damage upon businesses. The paper concludes with the suggestion that we may be witnessing a virtuous spiral whereby rising public expectations of morality in business lead to ever increasing moral commitments by business that then cause those expectations to rise still further.

How Environmental Management Competitive Pressure Affects a Focal Firm's Environmental Innovation Activities: A Green Supply Chain Perspective

Recently, environmental management offers firms a source of competitive advantage in the marketplace. The development of environmental innovations is critical to the success of today's firms. Drawing on the Schumpeterian perspective of competition, this research examines how the perception of rival firms' green success influences a firm to pursue and produce environmental innovation through its green supply chain integration activities. Using survey data from 230 firms, a conceptual model is developed and tested using structural equation modeling. We find that the firms in our sample do perceive pressure from their competitors' success in environmental management activities, and thus take supply chain action to pursue integration activities. By differentiating incremental and radical environmental innovation, this study also reveals the role of three dimensions of green supply chain integration (internal, supplier, and customer integration of green product development) on incremental and radical environmental innovation separately. Specifically, findings suggest that green supply chain integration has a positive impact on developing incremental environmental innovation, while only customer integration has a significant positive impact on developing radical environmental innovation.     

副井提升机制动力矩的计算与调整

提升机紧急制动减速度超标,主要原因是制动器贴闸压力过高造成的。依据《煤矿安全规程》的相关规定,演绎出计算贴闸压力的不等式,由不等式计算出贴闸压力的取值范围,在取值范围内确定贴闸压力的大小,按确定贴闸压力的大小对制动系统进行调试,其结果就可以避免紧急制动减速度超标的问题。     

轴心压力对Y型偏心支撑钢框架抗震性能的影响

偏心支撑钢框架是在支撑钢框架的基础上改进的一种新型抗侧力体系,该体系结合了中心支撑钢框架强度、刚度高和抗弯框架延性、耗能性能好的优点,是适用于高烈度地震区的一种有效的抗侧力结构体系。同时,由于多高层钢框架的广泛应用,其层数不同将会导致柱轴心压力的不同。本文通过应用ANASYS有限元程序对其在不同轴心压力下的受力性能进行分析。

Shopping enjoyment and store shopping modes: The moderating influence of chronic time pressure

The objectives of this study were to investigate: (a) whether shopping enjoyment has a differential influence on two key store shopping modes (browsing vs. bargain hunting); (b) whether the level of chronic time pressure moderates the influence of shopping enjoyment on each shopping mode; and (c) whether each of the shopping modes has a differential influence on hedonic shopping value. Data were collected from a sample of US store shoppers (n=1009). Results revealed that the influence of shopping enjoyment was much stronger on the browsing mode than on the bargain hunting mode. In turn, the browsing mode exerted a stronger influence on hedonic shopping value. Also, this study confirmed that the level of chronic time pressure significantly moderated the influence of shopping enjoyment on the browsing mode. Implications for brick-and-mortar retailers were discussed with suggestions for future research.     

特低渗透油藏间歇式生产油井产能预测分析

特低渗透油藏产能低,开发难度大已成为共识。为了对特低渗透油藏油井产能和油藏产量进行准确的预测,本文在达西公式的基础上,考虑到特低渗透油藏的渗流受到启动压力梯度的影响,推导出了具有启动压力梯度的间歇式生产的油井产能的预测模型,得出油井间歇式生产过程中采油量与时间存在指数递减关系;还推导得出油井关井时间段井底压力变化的数学模型,分析出其井底压力变化与采油时间段的采油速度有关,并给出了进行计算机迭代运算的求解方法和计算步骤。
