Changes in international competition lead to changes of the requirements on production enterprises. The introduction of new production technologies does not seem to be exclusively an adequate reaction to the increasing problems. Therefore tools of computer-integrated production (CIM) and new organizational concepts have to be conceived. Because these organizational and technical means are linked on the one hand with severe changes in the production system and, on the other hand, with rather higher economic risks in their realization, the effects have to be estimated in advance in the planning stage. Consideration of dynamical system behaviour plays an important part because the main goal is the improvement of order processing. This paper presents a simulation program, which can be used during the design phase of the organizational structure of production systems as a powerful tool for predicting the effects of new computer-aided tools and structures. 相似文献

The literature on transnational activism often associates environmental NGOs with democratic legitimacy, grassroots representation and environmental justice. Authors employ case studies to demonstrate how engaging in transnational networks increases the political agency of environmental NGOs. Yet, there is a tendency mostly to select successful cases. In this article, I investigate the political activities of the environmental NGO, Toxics Link, surrounding the recycling of electronic waste in India. Based on qualitative research, this study shows how the political incorporation of Toxics Link in transnational advocacy networks and domestic governance networks constrains their political agency. The structural exclusion of e‐waste labourers from Indian policy negotiations negates the discursive claims of legitimacy, representation and justice. These incorporation processes create a democratic deficit. I use the insights gained from this case study to provide a critical assessment of theories of transnational environmental activism. 相似文献

This article provides an overview of the development and validation of a Counsellor Task Analysis (Problem Gambling) [CTA (PG)] instrument undertaken in order to document the activities of counsellors in problem gambling services. The CTA (PG) aims to provide a broad overview of the complexity of the counsellor's role; specify the range of tasks they perform; and document the relationship between the frequency of task performance and the counsellor's beliefs about the importance of the tasks performed. The CTA (PG) instrument addresses nine dimensions of practice activity through nine subscales, all of which demonstrate internal consistency. It appears to be a strong instrument in terms of its measurement error characteristics for recommending its use with counsellors engaged in the field of gambling. The CTA (PG) gives counsellors the opportunity to document their practice and theories in use when dealing with a problem gambler, a member of the problem gambler's family and the community at large. The psychometric findings reported in this article should be viewed as the preliminary results of an ongoing research effort and further psychometric testing is anticipated. 相似文献

Causes underlying mortality disparities are often determined by causal decomposition. This method is based on the decomposition of differences in mortality or life expectancy into parameters representing the contribution of underlying causes. It quantifies disparities as differences in mortality rates and does not account for the fact that many underprivileged groups are more likely to die from nearly all causes. Results are driven by the frequency of cause of death. Alternatively, the cause deleted index quantifies the role of underlying causes in mortality disparities as the change in the relative risk of dying that is related to deleting a specific cause. The consistency between the methods in estimating cause of death contributions is analyzed using 2000 U.S. mortality data and simulated mortality profiles. The two methods often produce divergent results because causal decomposition relies on the prevalence of causes of death. 相似文献

The characteristics of policy in special education are examined in a number of international settings via an analysis of policy documents and commentaries on policy implementation. Through a constant comparative method a number of 'ideal types' are identified which characterise policy and exemplify the problems involved in the realisation of policy, particularly when that policy is progressive and especially when it promotes inclusive principles. Tensions particularly emerge between the interests of administrative and professional groups on the one side and the deprofessionalising, devolutionary pressures inherent in inclusion on the other. The types are used to analyse specific policy initiatives in Australia, New Zealand and the UK. 相似文献
