Advertising situated in environments where people congregate or pass through on their way to somewhere else benefit from being placed in such high traffic areas. However, these strategically placed ads also suffer from conditions of human crowding that prevents them from being noticed and processed. We undertake a study of place-based advertising in a shopping mall using facial recognition software to determine the effect of human density on the attention directed to advertising. We find that as human density increases, attention to advertising decreases, but only to a point where it begins to increase again. Our research also finds that human density plays a moderating role on the motivation to process advertising. 相似文献

For a variety of reasons, this article argues, electricity must be seen by policy‐makers in South Africa not as the sole provider of all future household energy needs, but rather as one component of an energy mix which includes such ‘transitional’ fuels as coal, gas and paraffin. The reasons for this are that electricity is expensive for poor households; it is subject to power failures and disconnections for non‐payment; the poor find it difficult to monitor and to control their consumption; appliances are expensive and several are required to make best use of electricity; people prefer other fuels because they are familiar and have strong personal and cultural associations, and because Eskom is not trusted owing to its past ties to illegitimate local authorities and misunderstanding of electricity and how its use is monitored and charged for. Further, it is mistaken to equate ‘development’ with total electrification: most developed countries have fuel mixes which include gas and coal, particularly for cooking and heating. Accepting an affordable fuel mix for the poor in particular would focus attention on the problems currently associated with paraffin, gas and coal, namely fires, poisoning and air pollution. 相似文献

Using results from surveys in which employers were questioned about their freedom to shed staff, we develop a measure of employment security in Europe. We seek to identify which institutional factors are correlated with the responses of employers and find that they appear to reflect the strength of legal restrictions and trade unions and the prevalence of atypical employment. Our results are used to compile an index of employment security that has both a temporal and a cross‐country dimension. 相似文献

Tom Wilson 《Industrial Relations Journal》1991,22(4):250-262
This article looks at industrial relations changes, conflict and control in higher education, particularly among university academics. It suggests a tendency towards proletarianisation, and a focus on the academic labour process is useful in explaining growing conflict. An apparent HRM agenda and (reluctantly) increasing managerialism are forms, not causes, of change which is driven by funding pressures similar to those affecting other HE systems. 相似文献

The threat to health from passive smoking is now well understood. Andrew Wilson, a freelance healthcare journalist, reveals the alarming results of recent research into ‘passive drinking’. Without wishing to cause alarm Economic Affairs wonders how seriously we should treat these new findings? 相似文献

All prestigious or highly-paid occupations in Britain are dominated by men: this is as true of the public sector as it is of industry. This article examines the evidence for discrimination in the public sector. It deals with both the situation at work and the one at home. It looks at various explanations as to why this is the case, as well as the evidence on how men and women deal with the inequality. The author concludes that there are good reasons why men and women do not see or confront the issues discussed in her article. Unless men and women wake up to the fact that we live in an unequal society and wish to see the glass ceiling well and truly broken, little is likely to change. 相似文献

Injection drug users (IDUs) transmit the human immunodeficiency virus (HIV) via both needle sharing and sex. Available interventions for this population have varying costs and effectiveness and focus on different risk behaviors. In this analysis, we look at two interventions. One is inexpensive, broad-based and provides modest risk reductions (street outreach (SO)); the other is narrowly focused, expensive and relatively effective (methadone maintenance). This analysis explores the effects of population risk behavior, intervention effectiveness, intervention costs, and decision constraints when allocating funds between these two interventions to maximize effectiveness. We develop a model of the spread of HIV, dividing IDUs into susceptibles (uninfected) and infectives, and separately portraying sex and injection risk. We simulate the epidemic in New York City for time periods from the mid-1980s to the early 1990s, and incorporate the behavioral effects of two interventions performed singly or in combination to find the allocation that maximizes the number of infections averted in the IDUs and their noninjecting sex partners, assuming interventions have increasing marginal costs. We find that the optimal allocation nearly always involves spending the maximum allowable amount on SO. This result is largely insensitive to variations in risk parameters, intervention efficacy, or cost. The model's structure, however, makes clear that many factors contribute to this insensitivity, namely the scope of the interventions, the dual drug/sex nature of HIV risk in the population, the asymmetry of sexual risk for men and women, and the potential benefits to nonIDUs. 相似文献

Many public and private organizations are developing and publishing clinical guidelines to assist health care providers and patients in making appropriate medical decisions. Unless clinical guidelines are part of a well-designed managed care program, they have little effect on physician practice styles. This article explores integral components of an effective guideline-based utilization management program. Initial evaluation of this program suggests that, as part of a well-designed utilization management program, clinical guidelines can inform patients and physicians, and create appropriate incentives for effective health care delivery. 相似文献
