In this paper, we develop modeling tools to forecast Value-at-Risk and volatility with investment horizons of less than one day. We quantify the market risk based on the study at a 30-min time horizon using modified GARCH models. The evaluation of intraday market risk can be useful to market participants (day traders and market makers) involved in frequent trading. As expected, the volatility features a significant intraday seasonality, which motivates us to include the intraday seasonal indexes in the GARCH models. We also incorporate realized variance (RV) and time-varying degrees of freedom in the GARCH models to capture more intraday information on the volatile market. The intrinsic tail risk index is introduced to assist with understanding the inherent risk level in each trading time interval. The proposed models are evaluated based on their forecasting performance of one-period-ahead volatility and Intraday Value-at-Risk (IVaR) with application to the 30 constituent stocks. We find that models with seasonal indexes generally outperform those without; RV can improve the out-of-sample forecasts of IVaR; student GARCH models with time-varying degrees of freedom perform best at 0.5 and 1 % IVaR, while normal GARCH models excel for 2.5 and 5 % IVaR. The results show that RV and seasonal indexes are useful to forecasting intraday volatility and Intraday VaR. 相似文献

Despite the popularity of online spaces that simulate aspects of consumption‐like experiences (online virtual worlds, video games and interactive functions on online retailers) conceptual tools that aim to comprehend such consumer practices are yet to emerge. In an effort to better understand them this paper puts forward a taxonomy that may help us capture emerging consumer behavior in the digital virtual terrain in relation to virtual and material consumption. This may be read as a fluid template that considers the movement between what resides in consumer imaginations as ideal or virtual, its actualization in material and now also digital virtual spaces. We then offer examples of the practices that are emerging, specifically the increase in imaginative resources that interactive media provide; practices that actualize probable, everyday commodities and experiences in the digital virtual and practices that actualize fantastic commodities and experiences in the digital virtual. Finally, we discuss the potential for these to produce new consumer subjectivities and new markets, and as a result we conclude with a discussion of the implications of such developments for consumer cultures, noting the potential for both liberatory/celebratory and critical discourse as well as avenues for future research. 相似文献

Pressures on the unit of resources within higher education are noted and the possible implications for assessment practice considered. There is a tension between low-cost and high-quality assessments, yet assessment appears to drive the students' agenda and requires careful thought if the programme design is to lead to high-quality learning outcomes. A theoretical framework is presented with the purpose of developing an assessment strategy which will enhance the quality of learning by the student. A case study of an introductory accounting module is described and issues of teaching, learning and assessment are explored. A message of hope is signalled; it may be possible to foster deep learning through assessments which engage the student actively with the subject, despite the apparent constraints acting upon academics. 相似文献

We examine a flexible assessment system that allows students to determine the weights allocated to each course component and to re-allocate the weights in response to achieved scores. The flexibility is intended to encourage students’ participation in the learning process, thereby promoting self-regulated learning skills. We compare this assessment system to a traditional system and to another system, in which the students may choose their own weights but cannot change them later in the term. We examine the impact on students’ motivation as measured by the Motivated Strategies for Learning Questionnaire (MSLQ), as well as the impact on grades and students’ attitudes. Our results indicate little improvement in motivation, grades or attitudes when students design and commit to their grading plans early in the term. However, the more flexible system, which allows for re-allocation, appears to improve students’ grades, self-reported motivation and attitudes. 相似文献

This work examines the interplay between temporal frame and one's accessible self-view on consumer response to health communication. We find an independent self-view is more persuasive with a distal temporal frame (versus proximal frame), and an interdependent self-view is more persuasive with a proximal temporal frame (versus distal frame). Message frame valence (gain versus loss) moderates the interplay between temporal frame and self-view. In addition, message concreteness and message persuasiveness are revealed as mediators to the interplay between temporal frame and self-view. Interestingly, the mediating process varies depending on one's accessible self-view. These findings offer guidance for health communication marketers' use of temporal frames and self-view. 相似文献

There has been an increasing trend in recent years for public agencies to work in partnership with each other and with commercial organizations, which has presented special managerial issues and problems. The Crime and Disorder Act 1998 gave the police and local authorities a statutory duty to work in partnership in order to promote and improve community safety. One such partnership is Safer Guildford, which was formed before the legislation came into force and which consequently already had a range of community safety initiatives in place. However, the partnership still had to comply with the new legislation and had to conduct an audit of crime and disorder in its area and publish a strategy for dealing with it. By examining the progress of Safer Guildford using a management perspective, a number of lessons can be drawn that will inform the future management of community safety partnerships. 相似文献

Knowledge management and innovation strategy in the Asia Pacific: Toward an institution-based view 总被引:6,自引:6,他引:0
The emergence of knowledge-intensive society has changed the nature of business competition. Knowledge management becomes
an important managerial task and formulating a sound innovation strategy is an integral part of strategic management. Adopting
an institution-based view, this article argues that the institutional environment in the Asia Pacific region plays a multi-faceted
role behind firms’ knowledge management and innovation strategy. Specifically, institutions impose rules for legitimacy, serve
as a source of knowledge, and allocate incentives and resources for innovation. We believe that future research drawing on
the institution-based view has significant potential to advance our understanding of knowledge management and innovation strategy
in Asia Pacific firms.

Developing theory from strategic management research in China 总被引:10,自引:9,他引:1
What are the main approaches to theory development based on strategic management research in China? What are some of the recent efforts in developing theory in this area? What is our recommended approach? To address these questions, this article outlines the three approaches to theory development in China research, articulates the Chinese context within the global economy, and highlights two streams of recent work as examples of following the recommended, integrative approach to theory development. 相似文献

Economic reform in Russia has been described as ‘shock therapy’ because rapid industrial privatization, price liberalization and democratic reforms of the political system were introduced simultaneously. However, shock therapy led to insider control of most manufacturing firms, with important consequences for foreign investment. In contrast, China’s ‘gradualist’ reforms, without privatization or significant democratization, facilitated foreign joint ventures as the dominant means of reforming State-owned enterprises incrementally. This paper proposes an explanation for these contrasting reform paths in Russia and China and then traces their consequences for inward foreign domestic investment (FDI), exporting and for corporate governance in the short and long term. The impact of national level policies on enterprises is demonstrated in a matched pair of cases in Russia and China. Conclusions are drawn for policy, for practice and for future research. 相似文献
