This study aims to determine whether the attitudes of students (and therefore future employers) towards people with physical disabilities can be modified by exposing them to the needs of disabled people, or whether perceptions of the needs of the disabled are too entrenched for education to effect any change. It also evaluates whether attitudinal changes are enduring and therefore continue to influence students' responses to the disabled after a period of time has elapsed.  相似文献

Employing a panel database, this article investigates empirically the behaviour, at an industry level, of cross-border mergers and acquisitions (M&As) in the People's Republic of China for the period 1991–2005. The study reports that many of the cross-border M&As over the past decades in China have been driven by broad fundamental factors, such as industry size and profitability. Moreover, technological intensity is significantly associated with the level of acquisition activity, indicating the tendency that intangible resources and intellectual capability favour more acquisition into China. It is found that deregulation, as a specific industry shock, affects acquisition activities significantly. The findings, it is concluded, have important managerial and policy implications.  相似文献

This study tests for underreaction and overreaction in European large cap markets by examining the abnormal returns of those stocks in the EuroStoxx 50 Index following large price increases and decreases. We find that large price increases and declines tend to be followed by average market returns. Thus, our results support the efficient market theory, rather than any of the behaviour finance hypotheses. This insight is contrary to price patterns found in various national markets.  相似文献

Using a frequency domain approach, we compare the spectra of equity market index returns for the 12 Euro-zone countries, the UK, the US, and Japan, over several time frames before and after the introduction of the Euro. In the immediate aftermath of the Euro-introduction, we find a reduced volatility over all frequencies, in which no strong cyclical components are present. However, in the long run, equity markets exhibit a volatility increase: the larger European equity markets develop dynamics that exhibit strikingly similar patterns, while the smaller European equity markets appear to follow dynamics closely resembling white noise. The similarity in dynamics is a likely candidate to explain the increase in correlation among the European markets. Furthermore, the European equity markets initially exhibited dynamics that resembled those of the US, while after the introduction of the Euro, the dynamics of the European Markets exhibits patterns similar to those found the UK. This suggests a change in the dynamic interdependency between the UK and the European markets and an increased convergence of UK market behavior with that behavior dominant in the Euro-zone. The findings may provide important implications for investors seeking to take advantage of international diversification.  相似文献

Bayesian networks (BNs) are graphical probabilistic models used for reasoning under uncertainty. These models are becoming increasingly popular in a range of fields including engineering, ecology, computational biology, medical diagnosis and forensics. In most of these cases, the BNs are quantified using information from experts or from users' opinions. While this quantification is straightforward for one expert, there is still debate about how to represent opinions from multiple experts in a BN. This paper proposes the use of a measurement error model to achieve this. The proposed model addresses the issues associated with current methods of combining opinions such as the absence of a coherent probability model, the loss of the conditional independence structure of the BN and the provision of only a point estimate for the consensus. The proposed model is applied to a subnetwork (the three final nodes) of a larger BN about wayfinding in airports. It is shown that the approach performs well than do existing methods of combining opinions.  相似文献

ABSTRACT. The spatial distribution of households and firms, or urban spatial structure, is a core element of the study of urban economics and the crucial determinant of commuting patterns. This paper examines developments in the analysis of urban spatial structure and commuting are related to the urban labour market—that is the analysis of labour supply and labour demand in a spatial context. These developments have been overlooked in the traditional approach to urban structure and commuting where most attention has been devoted to the markets for land and housing rather than the market for labour. Yet a little reflection suggests that the labour market might have a great deal to do with the location decisions of households and firms, and hence with commuting patterns. We argue that much criticism of the economic analysis of urban structure and commuting can be addressed by explicit incorporation of the labour market into the conventional model of urban location. This criticism includes findings that the theory cannot explain the tendency for richer households to live farther from the central business district and commute farther to work (Wheaton, 1977) and findings of substantial unexplained or 'wasteful' commuting according to conventional theory (Hamilton, 1982). The paper begins by outlining the basic model of residential location and commuting (Section 2). We then consider extensions that involve the introduction of labour supply decisions and which determine the value of commuting time (Section 3). More recent extensions involve the introduction of decentralized workplaces (Section 4) and, logically, the issues of job search and migration (Section 5). We conclude with a summary of the progress in incorporating labour market behaviour into the analysis of urban structure and commuting and our suggestions for further research in this area.  相似文献

Abstract : This paper reviews decisions of TUC Disputes Committees from 1974 to 1991. It considers whether the rather different conclusions of studies of earlier periods are still valid and assesses the effectiveness of 'Bridlington' in resolving disputes over new issues, in particular 'single-union deals'. It concludes that there is still a role for a voluntary disputes resolution mechanism of this kind, although recent experience has shown that it has its [imitations. TUC-affiliated unions will therefore lose a useful mechanism for promoting the efficient use of their resources if the 1993 change in the law leads to Bridlington being abandoned.  相似文献

Antitrust enforcement of supermarket merger activity during the late 1980s and early 1990s was less stringent than it had been before or has been since. For six announcements of supermarket acquisitions during this period, this study examines the abnormal stock returns of rival firms to determine if investors believed these acquisitions would lead to higher retail prices.These abnormal returns imply that investors expected that the average retail price change associated with these types of acquisitions ranges from a 0.12% decrease to a 0.05% increase. Thus, our results suggest that investors generally did not view these acquisitions as anticompetitive.  相似文献

Analysis of the reasons for trade union decline in developed economies has pointed to their failure to invest in effective methods of recruitment as a contributory factor. This article presents survey and case research to examine the extent to which union failure in recruitment and organizing has been rectified in the United Kingdom. The evidence indicates a varied but nevertheless substantial re-direction of union effort towards recruitment since the mid-1990s and is used to identify the characteristics of 'recruiting unions' which have invested more heavily and adopted more ambitious recruitment targets. Recruiting unions are found to be those which are receptive to learning new approaches to recruitment from overseas and which have relatively advanced arrangements for the representation of women and minorities in their internal systems of government.  相似文献
