This paper is based on a research study project on Premises and Process of Introducing Strategic Planning in a Company. It presents and discusses some major findings of the study concerning the content of strategic decisions, the elements of a planning system, the process of introducing strategic planning and the impact of environmental conditions upon the strategic planning system. 相似文献

From the start individualization theory is the investigation of the paradigm shift in social inequality. Furthermore it shows, how the transnationalization of social inequalities bursts the framework of institutional responses – nation state (parties), trade unions, welfare state systems and the national sociologies of social classes. In this essay I shall try to conceptually elucidate the ‘cosmopolitan perspective’ on relations of social inequality in three cases: (1) the inequality of global risk; (2) the Europe‐wide dynamic of inequality; and (3) transnational inequalities, which emerge from the capacities and resources to transcend borders. Before that I take up Will Atkinson's question: ‘What exactly constitutes individualization and to what extent has it really displaced class?’ ( Atkinson 2007 : Abstract) 相似文献

Purpose: There is no consensus on possible benefits and risks of testosterone supplementation. Here we review various controlled studies of testosterone supplementation in aging males.Methods: We performed a PubMed search using the terms “testosterone/therapeutic use” with the limits “>65 years of age”, “randomized controlled clinical trials”, and “male gender”, starting in 1999.Results: Forty-three articles have been published since 1999. Some of these studies also included patients in middle-age or younger. Findings reported in these articles were not entirely consistent. After weighting studies by the number of patients, hints are found that testosterone supplementation increases bone mass, lean body mass, muscle mass and hematopoiesis, and improves sexual functioning and perhaps mood, but does not affect serum lipids, cardiovascular parameters, prostate-specific antigen level, or cognition. Considering studies including only men older than 65 years, and in which testosterone supplements were compared with placebo treatment, slightly different results are obtained. In these patient groups, testosterone does not improve sexual function or mood.Conclusion: The overall benefit of testosterone supplementation for the aging male remains unclear. Any supplementation in men with age-normal testosterone levels only on grounds of subjective symptoms is not advisable. 相似文献

Abstract Objectives and Participants: Changes in body weight, composition, and size were examined in college freshmen at the beginning (initial, n = 240) and end of fall semester 2007 (n = 214) and the end of spring semester 2008 (n = 205). Methods: Height, weight, body composition, and waist and hip measurements were assessed. Results: Mean weight, body mass index (BMI), absolute and percent body fat all increased significantly over fall semester and the academic year. About 31% of freshmen lost ≥5 lbs. Mean academic year weight gain was 2.6 lbs (entire group) and 6.0 lbs (weight gainers); body fat increased by 4.4 lbs in the weight gainers. A significant correlation (r = .509) was found between weight change and waist circumference change, but not between weight change and waist to hip ratio change. Conclusions: Freshmen weight gain is associated with increases in body fat and waist circumference, which may be troublesome should the trend continue throughout college. 相似文献

过去数十年来, 多元性的文化、社会和政治图景演变甚巨; 然而我们却仍未找到 一种话语来描述、界定、理解、解释和研究当代世界的超级多元性。关于多元性的社 会思想和政治行动大多受制于民族主义方法论和多元文化主义框架; 然而, 对此应该 提出质疑。和民族主义方法论相对的世界主义方法论, 是观察多元性问题富有前景的 视角。另外, 对规范的、哲学意义上的“世界主义”和作为一种结构现象及社会科学 研究项目的“世界化”进行区分是非常必要的。我们可以把哲学及规范意义上的世界 主义与世界性社会科学结合起来, 构建一种世界性的现实主义。 关键词: 超级多元性 民族主义方法论 多元文化主义 世界主义 世界化 Over the last decades the cultural, social and political landscapes of diversity are changing radically, but we do not even have the language through which contemporary superdiversity in the world can be described, conceptualized, understood, explained and researched. Many of the social thoughts and political actions on issues of diversity are now dominated by methodological nationalism and multiculturalism which, however, have to be called into question. As opposed to methodological nationalism, methodological cosmopolitanism is a promising lens through which to look at questions of diversity. And it is essential to draw an essential distinction between “cosmopolitanism” in a normative philosophical sense and “cosmopolitanization” as a structural phenomenon and as a social scientific research programme. Philosophical and normative cosmopolitanism can be combined with cosmopolitan social science to create a cosmopolitan realism. 相似文献

Supply contracts are used to coordinate the activities of the supply chain partners. In many industries, service level‐based supply contracts are commonly used. Under such a contract, a company agrees to achieve a certain service level and to pay a financial penalty if it misses it. The service level used in our study refers to the fraction of a manufacturer's demand filled by the supplier. We analyze two types of service level‐based supply contracts that are designed by a manufacturer and offered to a supplier. The first type of contract is a flat penalty contract, under which the supplier pays a fixed penalty to the manufacturer in each period in which the contract service level is not achieved. The second type of contract is a unit penalty contract, under which a penalty is due for each unit delivered fewer than specified by the parameters of the contract. We show how the supplier responds to the contracts and how the contract parameters can be chosen, such that the supply chain is coordinated. We also derive structural results about optimal values of the contract parameters, provide numerical results, and connect our service level measures to traditional service level measures. The results of our analyses can be used by decision makers to design optimal service level contracts and to provide them with a solid foundation for contract negotiations. 相似文献

In most models of (cumulative) prospect theory, reference dependence of preferences is imposed beforehand and the location of the reference point is determined exogenously. This paper presents principles that provide critical tests and foundations for prospect theory preferences without assuming reference-dependent preferences a priori. Instead, reference dependence is derived from behavior and the reference point arises endogenously. 相似文献

This article develops a control chart for a mean vector when it is monitored by a quadratic form in the exponentially weighted observation vector. A Bayesian approach is used to incorporate parameter uncertainty. We first use a Bayesian predictive distribution to construct the control chart, and we then use a sampling theory approach to evaluate it under various hypothetical specifications for the data generation model. 相似文献
