A note on the Wang and Wang measure of the quality of the compass rose

H. Wang and C. Wang [Visibility of the compass rose in financial asset returns: A quantitative study, J. Bank. Financ. 26 (2002), 1099–1111] derive a measure of the visibility of the radial patterns that appear in a plot of current and past returns, which are more commonly known as the compass rose. In theory, this measure should be positively related to the tick/volatility ratio. In practice however, we find that this relationship does not hold for higher tick/volatility ratios that are common to stock market data. Thus, the use of this measure is limited in real world applications. We propose a correction factor that improves the behaviour of the quality measure over higher tick/volatility ratios, however, further research is required to fully identify and correct the problem.

The effects of unions on research and development: an empirical analysis using multi-year data

A link between unionization and research and development rates (research and development expenditures divided by output) is tested for in thirteen aggregate Canadian industries. A balanced panel of thirteen industries covering 1968 to 1986 reveals a negative relationship between industry unionization rates and research and development. The results hold when a number of techniques are used to control for unobserved industry heterogeneity and non-linear responses to unionization. In an industry that moves from the 25th to the 75th percentile of unionization, research and development is predicted to fall by about 40 per cent. JEL Classification: J51
Les effets des syndicats sur l'intensité de la recherche et développement: une analyse empirique sur plusieurs années . Ce mémoire examine le lien entre le degré de syndicalisation et les taux de dépenses en recherche et développement en proportion de la production dans treize industries canadiennes. Pour ces treize secteurs industriels, entre 1968 et 1986, il semble qu'il y ait une relation négative entre les taux de syndicalisation et les taux de dépenses en recherche et développement. Ces résultats sont robustesmême quand on utilise des techniques pour tenir compte de l'hétérogéneité des secteurs et des réponses non linéaires à la syndicalisation. Pour une industrie qui voit son taux de syndicalisation passer du 25e au 75e percentile, on prévoit une chute de 40% dans la recherche et développement.     

Board Pay and the Separation of Ownership from Control in U.K. SMEs

This paper examines Board pay for a sample of 571 U.K. SMEs from 1991 to 1995. Approximately half of the sample were closely-held (i.e., owner-managed) firms which allowed empirical testing of models of the relationship between Board pay and ownership from control characteristics. Consistent with their need to align shareholder and manager incentives, the results indicate that the change in nonclosely-held SME Board pay is significantly related to both external market pay comparisons and “benchmark” profits. This contrasts with the empirical results for the closely-held firms where Board pay awards are typically highly sensitive to current total profits but wholly unrelated to external market pay levels.     

意法半导体大手笔重组

2005年初,当Pasquale Pistorio在担任意法半导体公司首席执行官18年之后退休时, Carlo Bozotti接过了这一重任。Pistorio帮助这家法意合资的芯片制造商一跃成为充满平衡感、精妙之处和多样性的全球半导体工业巨人。接替Pistorio将面临极大的困难。现年53岁的Bozotti要面临重建公司增长、削减公司成本和鼓励公司创新营销等接踵而来的重任。简而言之, Bozotti的工作就是重组这家欧洲最大的芯片制造商,使其在比以往更加以消费者市场为导向的半导体行业中抓住更多的机会。     

Factors affecting consumer acceptance of chilled ready meals on the island of Ireland

The chilled ready meal market on the island of Ireland is relatively young but is growing rapidly. This paper focused on a consumer questionnaire (n = 702), designed to examine consumer attitudes to and consumption of chilled ready meals, in both the north and south of Ireland. This formed part of a larger study, with the questionnaire findings contributing to an in‐depth sensory study on a selected range of chilled ready meals. For a significant number of Irish consumers, consumption of these products is higher than on the UK mainland. For others, the products are purchased as a convenient alternative or a weekly treat. Respondents in urban locations were significantly more likely to consume chilled ready meals, as were men and younger, single respondents. Irish consumers are becoming more accustomed to ethnic cuisine although traditional meals remain popular. There is a clear need for developers to continue to enhance the sensory quality of these products, particularly as the primary barrier to consumption was a preference for home cooked food. However, they must also strive to maintain consumer interest in the sector, fulfil the desire for convenience and satisfy a more discerning palate.     

Professional service quality A step beyond other services?

The management and measurement of professional service quality is particularly problematic. To enable managers of legal practices to improve service quality they must understand the service attributes their clients consider important. Drawing on a series of focus groups conducted in the UK, this study provides insights into the assessment of legal services by commercial and corporate clients. A review of literatures pertaining to the evaluation of professional service quality, the concepts of quality and value, and dimensions relating to outcome and process is presented. The results of a series of focus groups are considered in the context of continuing research.
