This paper focuses on the process of Computer Aided Design (CAD) diffusion into a group engaged in the development of innovative products. Adopting an ethnographic approach, we build a grounded theory for interpreting CAD usage in terms of the interplay between variables such as management orientation, training, actors' specialisation and deskilling, availability of shared archives, technological discontinuities between organisational areas.  相似文献

Characterization and construction of optimal designs using the familiar optimality criteria, for example A-, D- and E-optimality are well studied in the literature. However the study of the Distance Optimality (DS-) criterion introduced by Sinha (1970) has very recently drawn attention of researchers. In the present article, we consider the singularly estimable full rank problem of estimating the full set of elementary treatment contrasts using the DS optimality criterion in the set up of a one way ANOVA model. Using a limit argument it turns out that a CRD in which difference between any two allocation numbers is at the most unity is uniquely DS-optimal. Acknowledgement. We are thankful to Prof. B. K. Sinha for suggesting the problem to us and many helpful discussions with him. We are also thankful to the referees for drawing our attention to the reference of Bischoff (1995) and many helpful comments.  相似文献

ABSTRACT The paper examines effects of executives’ orientations on crisis management awareness and practices, drawing on the simplicity and paradox management theories. It is suggested that a focus on single‐sided management constitutes an antecedent of crisis proneness. Employing a set of key corporate domains and based on a holistic organizational approach, the study aims at assessing the extent to which companies are crisis prone or prepared. In a sample of 82 Istaeli business and not‐for‐profit organizations it was found that human resource management, strategy, structure, and unlearning factors significantly predicted crisis preparedness. These results suggest that unlearning, despite a mere allusion to this correlate in the simplicity and paradox management theories, correlates better with crisis preparedness. By contrast, traditional strategy‐related and structural effects were marginally related to crisis management policies. Implications and suggestions for further research are proposed.  相似文献

旅游业已经成为现代经济增长一个新的亮点,特别是生态文化旅游的增长速度更是惊人,而其发展的价值平衡是生态学和经济学必须面对的一个难题。本文依据意大利经济学家帕累托的不均匀分布定律,运用埃奇渥斯盒状分析图,在某一选定的生态资源环境的承载量既定的基础上,从生态文化旅游的价值交换的角度考虑,并且从定性研究转向定量研究,分析研究生态文化旅游的价值帕累托最优曲线,用以筛选生态文化旅游的工程项目。  相似文献

One hundred and fifty‐eight bankers, accountants and corporate lawyers, aged under 40 years, earning more than £50,000 annually and working in the City of London were questioned about their attitudes and behaviour in relation to charitable giving. A conjoint analysis of the respondents' preferences revealed strong predilections for certain types of charitable organisation; for ‘social’ rewards in return for donating (invitations to gala events and black tie dinners for example); and for well‐known charities with established reputations. ‘Planned giving’ whereby donors receive tax breaks and other financial incentives to donate (as increasingly practised in the USA) did not represent a significant inducement to give so far as this particular sample was concerned. Overall the results suggest that young affluent male City employees constitute a distinct market segment for charity fundraisers, with unique characteristics that need to be addressed when developing donor products.

This paper examines the capacity of the London (2012) Olympic Ambassador volunteer programmes to create a sustainable tourism legacy. It contributes to the literature on event legacies, particularly the role of volunteers promoting tourism in their home destination. Using an exploratory inductive approach, semi-structured in-depth interviews were conducted, in 2012 and 2013, with managers of all 11 Ambassador volunteer programmes associated with London and the 10 other regional venues that hosted London Olympic and Paralympic Games events. These show that volunteer Ambassadors enhanced tourist experiences during the Games through the Ambassadors’ pride in their home city, enthusiasm and local knowledge. However, although the Ambassador programmes had aspirations to create a sustainable legacy, in the form of a pool of experienced volunteers to support future events and further tourist visits, this was severely constrained by cuts in local government budgets. The Government Olympic Executive provided a coordinating role leading up to the Games, but neither they nor the London Organising Committee for the Olympic Games provided practical assistance for legacy development. This was a missed opportunity to channel the enthusiasm of mega-event volunteers into further volunteering to promote tourism.  相似文献

本文应用基于条件多元t分布的DCC-MVGARCH模型研究CERs期货价格收益同能源期货价格收益之间的动态相依关系,旨在探讨跨品种套期保值的可行性及操作策略,为国内减排企业及时对冲CERs价格波动风险提供经验依据。实证结果显示:CERs期货价格收益和能源期货价格收益之间存在正相关性;相较Euro天然气期货合约与GlobalCoaL期货合约,BRenT原油期货合约更适用于构造套期保值组合;以动态条件相关系数测算时变套期保值比率明显降低了组合收益的方差并提升了组合收益的均值,其套期保值绩效要优于条件相关系数。基于此结果本文认为,国内减排企业应当积极采取相关套期保值策略并定期更新动态条件相关系数均值,政府主管部门亦应着手实施碳资源战略储备以对冲风险。  相似文献
