This paper uses the genetic algorithm (GA) approach to generate a portfolio optimisation scenario of a South African investor who seeks to maximise return from investing in S&P500, FTSE100, NASDAQ, DOWJONES, CAC40 and the DAX from January 1, 2005, to January 31, 2008, but facing exchange rate risk. The GA searches for the optimal solution in the entire set of financial constraints without looking for partial derivatives of the utility function. Whereas most financial problems require a non‐linear and time‐varying model, the GA, with its survival principle of offspring chromosomes, is better suited to this type of problem than local optimisation methods. The performance of the GA is compared with two non‐linear models, namely the quadratic mean‐variance (QMV), which maximises the portfolio mean‐variance, and the quadratic variance minimisation (QVM), which minimises the portfolio variance. The results show that neither the QMV nor the QVM takes into account the domestic investors' risk attitude towards investing in foreign equities and therefore does not provide any international diversification benefits. In addition, the bootstrapping scenario of 10,000 simulations reveals that neither the QMV nor the QVM outperforms the GA in terms of Sharpe ratio and flexibility in dealing with investors' risk attitude towards investing in foreign equities denominated in foreign currencies. 相似文献

Reasons for the great impact of World Dynamics and Limits to Growth include their addressing the correct audience (the public), and the ability of systems dynamics clearly to handle and communicate information on complex and often little understood areas. Modelling projects should usually be global or national (not regional), draw heavily on mental and not just written and numerical databases, and have time horizons of perhaps 100 years. Sadly, critics of Worlds 2 and 3 have yet to come to grips with the fundamental messages presented there, although these messages are becoming increasingly vital. 相似文献

The transformation of Poland’s economic system in the 1990s as a result of transition from a centrally planned economy to a market-based system involves significant changes in the regulatory context and in accounting practice and education.This paper presents the scope of application of management accounting concepts and methods in 60 Polish enterprises covered by a questionnaire survey carried out by the author between November 1998 and December 1999 in enterprises located in central and southern Poland. The selected companies were interviewed by means of a postal survey, with inquiry forms delivered in person in some cases.The detailed analyses carried out in this paper and the conclusions presented are also based on information obtained from documentary evidence kept by the enterprises and from direct interviews conducted in the course of work in teams engaged in analysis and assessment of cost accounting practices and in management accounting system design in a number of large and medium Polish enterprises.The empirical research carried out is aimed at verification of a number of hypotheses including the following: • modification of cost accounting systems and implementation of management accounting tools in Polish enterprises is brought about by many different factors, the most important being growth of competition and ownership changes in business entities, • Polish enterprises mostly implement the methods and techniques of operational management accounting, • short-term budgeting for cost centres is the most widely used method of management accounting. 相似文献

原型范畴理论作为认知语言学概念的基础近年来逐渐得到了语言学家的重视。原型范畴理论可以用于英语教学并对英语时态具有一定的解释力,从而为英语时态教学开辟新视角。本文以一般现在时态、一般过去时态、一般将来时态为例,探索原型范畴理论在英语时态教学中的应用。希望能推动该理论在英语时态教学中的应用。 相似文献

理论界对文娱新闻的关注大多集中在对其低俗化的批判上,对其社会价值、未来发展方向等深层次的研究相对比较缺乏。本文对文娱新闻的未来发展进行了大胆的预测。文娱新闻的发展有赖于社会的进步和传媒业的发展,同时也有赖于从业人员文化素质的提高和思想水平的进步。文娱新闻包含娱乐,但并不是只有浅表化的娱乐,而是要在娱乐的同时构筑较高的文化品住,在娱乐的过程中提升文化,提高素养,这才是文娱新闻可持续发展之道。 相似文献

The New Public Management agenda for change has been extremely influential. This paper considers future developments in NPM. In this evaluation of the future of NPM it is argued that the complexity of NPM – in concept and in practice – requires a multi‐dimensional consideration of what NPM is and what it will become. In this paper, NPM is explained around three key dimensions: (1) management processes; (2) mechanisms of change, and (3) constraints. Within these three dimensions, nine key elements of NPM implementation are discussed. This paper concludes that the pressures for NPM will not abate. However, its evolution will continue to be severely contested. 相似文献

我国是世界第一大苹果和苹果汁生产国,苹果汁出口占据世界贸易量一半以上。分析我国推出浓缩苹果汁期货在抵御价格风险、提高果农收入、赢得反倾销诉讼、促进产业发展等方面的必要性。同时进一步从苹果汁现货市场发育程度、产业规模、厂商数量、交割标准制定等方面进行可行性分析。浓缩苹果汁期货的上市,可以使我国牢牢掌握苹果汁的定价权,促进整个苹果产业链的健康发展。 相似文献
