Using a sample of Australian Multi-sector trusts we examine selectivity and market timing performance and extend the analysis to include the relatively new measure of volatility timing. This is of particular relevance to our data set, as high levels of volatility persistence are prevalent in Australia. In addition we consider the stability, asymmetry and seasonality of the various performance and risk measures. A survivorship adjustment procedure is also employed in order to assess the impact of survivorship on selectivity, market timing and volatility timing performance.  相似文献

The evolution of society and economic pressure has provided the impetus for operating on a 24-hr basis in many industries. This has occurred with relatively little attention toward sleep deprivation and related problems facing shift workers and the organizations employing them. This paper first documents the move toward shift work and some sleep problems associated with it. We then describe sleep disorders that impact job performance. Next, we describe alternative schedules and give suggestions for shift work implementation. Finally, we offer some normative advice regarding the treatment of shift employees.  相似文献

This article assesses the shape of industrial growth at the western end of the US‐Mexican border, analysing the degree to which globalization has diminished and/or restructured this international division. Baja California's connection to external economies is highly variable in tourism, agribusiness and export processing, with electronic maquiladoras clustering and garment production fragmenting. Most recently, dynamism has been driven by Asian investors meeting NAFTA deadlines, and impeded by recession and increased border security. The polarizing effect of globalization is demonstrated by the unprecedented emergence of a powerful group of Mexican‐state and private‐sector technocrats, at the expense of the majority of workers whose jobs remain poor. The state government has facilitated the development of capital intensive electronics industries, has neglected small and medium domestic suppliers, and been unable to provide public security. Low extensity, or the concentration of maquiladoras in an east‐west corridor adjacent to the border, and the location of most of their owners in Southern California, indicates the strongly regional character of the maquiladora economy. However, a small number of very large capital intensive plants originate in Asia, contributing to globalization via intercontinental linkages. The findings support transformationalist and sceptical models of globalization. L'article évalue la forme de croissance industrielle à l'extrémité occidentale de la frontière américano‐mexicaine, en analysant dans quelle mesure la mondialisation a atténué et/ou restructuré cette séparation internationale. La péninsule de Basse Californie est reliée de façon très variable aux économies extérieures, par le tourisme, l'agro‐industrie et la transformation à l'exportation, avec un regroupement de maquiladoras d'électronique et une fragmentation de la production vestimentaire. Plus récemment, si le dynamisme est venu d'investisseurs asiatiques en des échéances de l'ALENA, il a été entravé par la récession et une sécurité frontalière accrue. L'effet polarisant de la mondialisation est réävélé par l'émergence d'un puissant groupe de technocrates du secteur privé et de lÉtat mexicain, aux dépens de la majorité des salariés dont les emplois restent médiocres. Négligeant les petits et moyens fournisseurs nationaux, le gouvernement a facilité l'essor de secteurs capitalistiques de l'électronique, tout en se montrant incapable d'assurer la sécurité publique. La faible extensibilité ou la concentration des maquiladoras sur une bande Est‐Ouest longeant la frontière, ainsi que l'implantation de la plupart de leur propriétaire dans le sud de la Californie, marquent le caractère fortement régional de ce type d'économie. Toutefois, un petit nombre de très grosses usines capitalistiques viennent d'Asie, contribuant à la mondialisation via des liens intercontinentaux. Les résultats corroborent les modèles de transformation et sceptique de la mondialisation.  相似文献

Financial Accounting Standard (FAS) 133 requires business entities to document their anticipation of hedge effectiveness in order to qualify for hedge accounting treatment of gains and losses from financial derivatives. In the absence of specific guidelines, the accounting industry has espoused the "80–125" rule for determining hedge effectiveness. But the authors observe that meaningful assessment of anticipated hedge effectiveness must consider two distinct aspects of a firm's hedging strategy: (1) the strength of the hedging relationship, which is determined by the choice of the hedging instrument; and (2) the position taken in the hedging instrument relative to the holdings of the hedged item. They take both aspects of hedging into consideration in developing alternative measures of hedge effectiveness and distinguishing between the potential and attained effectiveness of a particular hedge. This approach enables the user to evaluate the relative merits of alternative hedging strategies to support risk management decisions, and also to document a selected hedging strategy's anticipated effectiveness for purposes of compliance with FAS 133. While the authors endorse a fairly broad interpretation of hedge effectiveness, their approach can also be used in the narrower context of an "80–125" rule.  相似文献

Different viewpoints were expressed at the 1990 annual national conference of the South African Society for Agricultural Extension regarding the role of extension in the development of the farmer as entrepreneur. It is expected that public funding will increasingly be limited to functions of general public interest. To achieve independence farmers should be willing to expose themselves to entrepreneur development stimuli. it is in the public interest to develop scarce human, economic and natural resources. Research findings indicate distinct behavioral differences between entrepreneurs of differing perceptions. A comprehensive interdisciplinary education is recommended for agriculturalists. Because needs change, education programmes must be re‐evaluated from time to time. It serves little purpose to educate people in extension who do not have a technical message to communicate. The state extension service seeks closer cooperation and liaison with agricultural co‐operative and private sector know‐how. Departmental policy will probably be less rigid in future.

A clear distinction should be made between information and extension services. The adoption of an ethical code for extensionists may be opportune. Relevancy is an important contributing factor to extensionist credibility.  相似文献

E-business processes between insurance companies and their private customers allow — in comparison to conventional business processing — savings in administrative expenses up to 30 per cent. However, today’s e-business processes are often described as little transparent and stereotyped. Users, therefore, complain them being far to complex and, as a consequence, do not accept them. Relating to research in the field of customer behaviour, it has been proved that even in e-business processes customers like to be contacted and treated individually. This can be reached by corresponding to the cognitive ability and the personal involvement of each customer. By using those mechanisms information processing becomes ?hospitable‘ or even ?human-alike‘. Chatter-bots simulate human behaviour in e-business processes and will possibly replace personnel in certain areas. Therefore, chatter-bots seem a suitable instrument to introduce successfully e-business processes between insurance companies and their private customers. Two positive consequences could be reached: first, process efficiency could be raised and second, cost-savings in processing could be gained.  相似文献

Workers engaging in voluntary and unrewarded environmental actions that go above and beyond their job requirements in an organizational setting can crucially contribute to a reduced environmental impact of organizations. This research investigates some of the factors that may contribute to the emergence of such organizational citizenship behaviour directed towards the environment (OCBE). The hypotheses predicted employees' concern for the environment, employees' perceived organizational support for environmental efforts and organizational commitment as antecedents of OCBE. Employees from two organizations (n = 547) completed an online survey. Controlling for organizational tenure, a significant relationship between (a) employees' concern for their environment and OCBE, (b) perceived organizational support for environment efforts and OCBE and (c) organizational commitment and OCBE were found. Furthermore, organizational commitment mediated the relationship between perceived organizational support for environmental efforts and OCBE, but not environmental concern. This study's insights into the factors that can drive employees' engagement in small, voluntary environmental actions at work can guide organizations wishing to encourage such behaviours.
