The closing decades of the 20th century will see radical changes taking place in the socio-economic structure of the U.K.—socially, with the growing displacement of labour due to the increasing use of ‘intelligent machines’ and coincidentally with a continuing reduction in the economically active population: economically, with the growing polarization between the industrial North and the post-industrial South. Such perceived developments, closely related to each other, will demand a positive response from U.K. retailing which could lead to a significant re-structuring of the industry as a whole.  相似文献

The first half of this article considers recent developments in the retail banking market and, with the aid of tables, describes the present state of the market. Emphasis is placed on the increased competitiveness of the market with more institutions involved in providing more products than ever before, and with more attention being focused on the unbanked sector of the population. The second half of the article considers the factors which are most likely to influence the ruture development of the market—both external influences such as the political, economic and regulatory environment and factors which lie more directly under the control of the banks themselves, such as the introduction of new services and branching policy. The article ends by stressing the scope for individual banks to pursue distinctive policies in this market in future.  相似文献

This paper examines the problem of decisions about the disposal of sewage sludge, in the face of stakeholder groups with varying viewpoints, based on a current case from the state of Lower Saxony in Germany. Like other developed countries, Germany faces the dilemma that sludge arisings are increasing (e.g., because of better water treatment) while disposal options are becoming more scarce. Lower Saxony relies heavily on landfill and agricultural application, but landfill of untreated sludge will be banned after 2005. The state Environment Ministry sees agricultural application as having various advantages, but it faces scepticism from various stakeholders. The ministry has therefore taken steps to encourage a long-term dialogue process with the main stakeholders, including farming organizations, food processors, other landowners such as the churches, and environmental and consumer organizations. The process began with a discussion forum in 1995 that led to the proposal of specific discussions with stakeholders. This paper focuses in particular on the dialogue with environmental and consumer groups. It analyzes the initial positions of the various stakeholders, describes the concrete steps taken so far, describes the ongoing efforts, and critically evaluates the procedures used as well as their implications in terms of the ideas of deliberation and analysis.  相似文献

The Kaplan–Meier estimator of a survival function requires that the censoring indicator is always observed. A method of survival function estimation is developed when the censoring indicators are missing completely at random (MCAR). The resulting estimator is a smooth functional of the Nelson–Aalen estimators of certain cumulative transition intensities. The asymptotic properties of this estimator are derived. A simulation study shows that the proposed estimator has greater efficiency than competing MCAR-based estimators. The approach is extended to the Cox model setting for the estimation of a conditional survival function given a covariate.  相似文献

The research on which this paper is based is part of a wider study of quality assurance and the voluntary sector. The focus of this paper is on complaints procedures, as part of quality assurance mechanisms, where voluntary agencies are the contracted service providers. The authors argue that, with the introduction of contracting and particularly with its further development, the way in which complaints mechanisms currently operate will need to be revised if they are to be an effective part of the quality assurance process.  相似文献

The Interpretation of Line of Regard by Prelingually Deaf Children   总被引:2,自引:0,他引:2  
The ability of 5- to 12-year-old deaf children to utilise and interpret another person's visual line of regard (where the eyes are looking) was studied in four experiments using cartoon faces. The children had little difficulty in determining whether or not a face was looking directly at them. They had more difficulty, however, with more complex tasks requiring them to infer mental states of desire and intention from line of regard and to ignore line of regard when it was inappropriate to attend to this cue. Deaf children raised in a hearing environment appear to have more difficulty with these more complex tasks than hearing children. The results are discussed in terms of the special difficulties facing some deaf children in the development of skills involving utilisation of line of regard and the implications for the development of joint attentional behaviour, theory of mind and dyadic social interaction in deaf and hearing children.  相似文献

Studies have examined effects of various personality variables, including extraversion and neuroticism, as well as age, on driver stress. However, the effect of the morningness-eveningness dimension (circadian type) on reported driver stress among commuters has not been investigated. This study aimed to assess the influence of circadian type as well as extraversion, neuroticism and age on driver stress. Participants were 101 Australian university administrative staff who completed the Eysenck Personality Questionnaire-Revised, the Morningness-Eveningness Questionnaire, and also morning and evening driving diaries as a state measure of driver stress each weekday for one week. Two standard multiple regressions assessed whether neuroticism, extraversion, circadian type and age predicted reported driver stress for morning and evening drives. Neuroticism, circadian type, and age predicted reported driver stress in the mornings but age mainly predicted driver stress in the evenings. A repeated measures ANOVA isolated differences between circadian types for weekday mornings and evenings. Reported driver stress differed for day of week and time of day according to circadian type. The three-way interaction suggested that driver stress is influenced by circadian type and that factors influence driver stress differentially between mornings and evenings. Circadian type appears to influence when driver stress affects individuals.  相似文献
