Dissecting the Random Component of Utility

We illustrate and discuss several general issues associated with the random component of utility, or more generally unobserved variability. We posit a general conceptual framework that suggests a variance components view as an appropriate structure for unobserved variability. This framework suggests that unobserved heterogeneity is only one component of unobserved variability; hence, a more general view is required. We review a considerable amount of empirical research that suggests that random components are unlikely to be independent of systematic components, and random component variances are unlikely to be constant between or within individuals, time periods, locations, etc. We also review evidence that random components are functions of (elements of) systematic components. The latter suggests considerable caution in the use and interpretation of complex choice model specifications, in particular recently introduced forms of random parameter models that purport to estimate distributions of preference parameters. Several areas for future research are identified and discussed.     

The Importance of Understanding Student Learning Styles in Accounting Degree Programs

Improvements in the tertiary education of accounting students benefit the profession. Analysis of the interaction of learning styles and teaching methodologies in accounting degree programs revealed that when learning styles matched teaching methods used, usefulness was assessed as high. When they differed, usefulness deteriorated. To maximise educational benefit this interaction should be considered, but this has resource implications. Accounting education is critical and any improvements in the tertiary education of accounting students should result in better prepared graduates entering the profession. This study evaluates accounting students’ learning styles and the interaction of learning styles and teaching methodologies in degree programs. Nine classes of accounting students (648 students) spread across four years and two degree programs were evaluated. Students self‐evaluated their learning styles, pre‐instruction. They were then subject to two separate teaching techniques (one active and one passive) in each course. Learning styles were then re‐assessed and teaching techniques evaluated. Accounting students displayed a preference for passive learning, even those far advanced in their degrees. Furthermore, when learning styles matched teaching methods used, usefulness was assessed as high but when learning styles and teaching methods differed, usefulness deteriorated. Overall, active learners rather than passive learners deemed the teaching methods to be more effective. The implications are significant. To maximise educational benefit for the accounting profession, student learning styles should be assessed before designing appropriate teaching methodologies. This has resource implications, which would have to be considered.     

Returning to flight: simulation‐based training for the US National Aeronautics and Space Administration's Space Shuttle Mission Management Team*

Following the tragic loss of Columbia in early 2003, executives at the National Aeronautics and Space Administration implemented a simulation‐based training program to facilitate the development of the Space Shuttle Mission Management Team (MMT). This article discusses the findings from an evaluation of two multi‐day simulation training events. The results of both evaluations suggested that MMT members: (1) possessed shared beliefs in their joint capabilities to execute their corecompetencies; (2) were motivated and ready for their Return to Flight mission; (3) achieved targeted levels of team performance during the simulations; and (4) were both satisfied with the training program and found it useful for facilitating performance improvements. This note concludes with a discussion of lessons learned.     

The birth of a nation: Accounting and Canada’s first nations, 1860–1900

The 1860–1900 period was both the “birth” of Canada but also the birth and institutionalization of a specific set of social relations between the federal government and First Nations peoples. This study examines the roles played by accounting and funding relations within the process of nation building. Throughout this formative period in Canada’s history, governance was attempted via the introduction of financial legislation and enacted by the Indian Department and agents in the field. As our analysis highlights, legislative initiatives, Indian Department pronouncements and the activities of agents imposed, enlisted and implied a variety of accounting technologies. This study not only explores how the federal government has used accounting/funding mechanisms in the attempt to translate government policy regarding indigenous peoples into practice but also provides a history of the present by examining the historical consequences of these interventions.     

别对Apple的选择大惊小怪

2005年6月,Apple Computer(苹果电脑公司)宣布将为其Macintosh个人电脑配置Intel公司的处理器.一石激起千层浪,主流媒体立刻对此事展开了连篇累牍的报道.Apple公司在其于旧金山举办的"全球开发者论坛"上宣布这条消息后仅数小时,从喜欢寻根问底的财经专栏记者到激进的技术批评家对事态的发展做出了各种各样的预测,其中不乏像"Apple和Intel不日即将合并"的惊人言论.然而,Apple此举给电子行业带来的影响似乎与铺天盖地的报道并不成正比.Apple此举到底将影响哪些人?影响又到底有多大呢?

How buyers' expected benefits, perceived risks, and e-business readiness influence their e-marketplace usage

The main objective of this study was to investigate how buyers' usage of electronic marketplaces was influenced by their perceived risks and expected benefits associated with such markets. A large scale survey involving 359 professional buyers was performed. Results indicated that buyers' perceived risks and expected benefits had an influence on their usage extent of electronic marketplaces. In addition, buyers' e-business readiness moderated the relationship between expected benefits and usage of electronic marketplaces. Managerial and theoretical implications of these results are discussed.
