Using data for a one-year period from the Kingston Public Hospital (KPH) in Jamaica, we describe patterns of non-fatal violence-related injuries, and carry out simulation analysis to estimate rates of hospital admission under various injury reduction scenarios, and the potential savings that can be realized by reducing violent crimes. In this period there were 6107 registered violence-related visits to the KPH representing 11.5% of all recorded visits. Of these 16.6% (1001) were admitted. The most common methods of inflicting injury was by stabbing (52.1%), blunt injuries (37.9%) and gunshot wounds (7.3%). Multivariate analyses indicated that gunshot injuries, stab injuries, being male between the ages of 15 and 44 years, receiving the injury in November or December, and being injured by a stranger or unknown assailant, were significant correlates of a higher probability of admission. Simulation analysis with various injury reduction scenarios indicated decreases in the probability of admission ranging from 12% to 44%, with estimated savings of up to 31% of the annual supplies budget of KPH.  相似文献

The last 40 years have seen an extensive literature documenting so‐called anomalies in major capital markets. Evidence of ‘abnormal’ returns associated with trading strategies based on readily observable phenomena such as accounting‐based data involves experimental design choices that can be expected to influence the results. We show how evidence of an accrual anomaly in Australia is sensitive to research design specifications such as the choice of proxy for total accruals; the definition of abnormal returns (i.e. the return generating model); the impact of data trimming as a response to exceptionally large returns; and the choice between value and equal weighting of returns. We show that research design choices do matter and help reconcile conflicting prior evidence of any accrual anomaly in Australia. More broadly, our results suggest the need for caution in drawing inferences from trading strategy tests which claim to identify anomalies.  相似文献

Personal presentation attributes have long been understood to affect perceptions of competence and capabilities. To that end, this study investigates seven attributes associated with favorable interview presentation, including overall physical attractiveness, neatness and grooming, clothing color, conservative versus trendy attire, professional versus casual attire, and body modification (including tattoos and piercings). Participants (n = 108), including students, faculty, and hospitality industry professionals, sorted an orthogonal array of 16 full-color, laminated cards that contained photos so that respondents could see levels of clothing color, clothing conservativeness, and degree of professional attire. The remaining attributes and their corresponding levels were shown on respective analog indicators. The conjoint analysis results indicate that grooming and professional attire are the most important attributes in shaping favorable perceptions. Furthermore, faculty perceived conservative clothing to be better while students and industry professionals indicated that trendy clothing creates a more favorable presentation on the part of a job candidate.  相似文献

There are a range of solutions that address asset building challenges for low-wealth women. Here we highlight some solutions that focus on basic needs (child care, child support) and creating economic stability with disposable income (income available after basic needs are met); solutions that address predatory lending and the housing crisis; and solutions that focus on joint ownership of assets and community-based asset building.  相似文献

Causes and effects of occupational stress have received research attention for several decades, with increasing focus during the 1990s as organizations and individual workers attempt to adapt to economic change. Stress arising from either the work or home domain can have a variety of outcomes in the workplace, and similarly can impact in many ways on relationships and activities at home. This paper reports the first phase of a research study to identify the impact on work and home life of changes in retailing, a sector of the economy which has experienced significant change over the past few years. A qualitative methodology was adopted, using group discussions to allow staff to identify the specific changes in retailing most important for themselves, and then to explore how these changes related to satisfactions and dissatisfactions at work, and their impact on general aspects of home life. The results suggest that the 'spillover' relationship between work and home stress seems to be the most useful in describing the impact of change. This suggests that additional role demands at work brought about by change have an impact on relationships and social life outside work. However, some individuals described instances of 'compensation' between work and home, and independence between the two domains. This suggests that the issue of stress in the home/work interface is complex, and that the demands in each domain may be positively or negatively related depending on characteristics of the demands themselves, or may vary according to individual characteristics of the people in the study.  相似文献

The influence of the environment on the emotional responses and behaviors of consumers has been well established in the consumer behavior literature. The Behavioral Perspective Model (BPM) assumes that utilitarian reinforcement, informational reinforcement, and consumer behavior setting scope are independent dimensions of environmental influence, which can combine in particular consumption situations to produce consumer behavior. This paper empirically examines the possibility of interactions among these dimensions by means of the pleasure, arousal, and dominance (PAD) emotional variables. The PAD variables have been shown to mediate consumer behaviors such as the desire to stay or escape from the setting, to affiliate with others, and the willingness to spend money and consume. The results, showing an interaction between pleasure and arousal in high‐pleasure environments, which then leads to increased approach behavior, seem to confirm the synergistic effects of utilitarian reinforcement and informational reinforcement on behavior. This study appears to be the first to find and investigate a three‐way interaction between pleasure, arousal, and dominance in the context of purchase and consumption. This interaction suggests that the three structural dimensions of the BPM combine to produce consumer behavior. It also highlights the important role of consumer behavior setting scope in consumer situations maintained by intermediate patterns of reinforcement. The implications of these findings for theory and marketing management are discussed.  相似文献

Abstract

The traditional theory of collective risk is concerned with fluctuations in the capital reserve {Y(t): t ?O} of an insurance company. The classical model represents {Y(t)} as a positive constant x (initial capital) plus a deterministic linear function (cumulative income) minus a compound Poisson process (cumulative claims). The central problem is to determine the ruin probability ψ(x) that capital ever falls to zero. It is known that, under reasonable assumptions, one can approximate {Y(t)} by an appropriate Wiener process and hence ψ(.) by the corresponding exponential function of (Brownian) first passage probabilities. This paper considers the classical model modified by the assumption that interest is earned continuously on current capital at rate β > O. It is argued that Y(t) can in this case be approximated by a diffusion process Y*(t) which is closely related to the classical Ornstein-Uhlenbeck process. The diffusion {Y*(t)}, which we call compounding Brownian motion, reduces to the ordinary Wiener process when β = O. The first passage probabilities for Y*(t) are found to form a truncated normal distribution, which approximates the ruin function ψ(.) for the model with compounding assets. The approximate expression for ψ(.) is compared against the exact expression for a special case in which the latter is known. Assuming parameter values for which one would anticipate a good approximation, the two expressions are found to agree extremely well over a wide range of initial asset levels.  相似文献

It is no longer a revelation that companies have some responsibility to uphold human rights. However, delineating the boundaries of the relationship between business and human rights is more vexed. What is it that we are asking corporations to assume responsibility for and how far does that responsibility extend? This article focuses on the extent to which economic, social and cultural rights fall within a corporation’s sphere of responsibility. It then analyses how corporations may be held accountable for violations of such rights. Specifically, the article considers the use of soft law as a protective mechanism; it also details how victims of harmful corporate behaviour are using litigation (pursuant to ATCA and common law domestic causes of action) to seek redress and recognition of the harms they have directly or indirectly experienced. The article concludes with an analysis of Professor Ruggie’s (the United Nations Special Representative on the issue of transnational corporations and human rights) 2008 and 2009 Reports in which it is suggested that a respect-based framework must be interpreted as imposing proactive requirements on companies to prevent the infringement of human rights. Future efforts must also be directed towards the recognition of a specialised complementary corporate responsibility to protect human rights.  相似文献
