This study was undertaken to discern differences between high, moderate, and low museum attendees. One-way analysis of variance and stepwise discriminant analysis were used for market segmentation purposes to differentiate the characteristics of the three groups. The discriminant analysis yielded a model which was found to predict better and was significantly different from the proportional chance prediction, and it is thus felt that a viable method for segmenting museum-goers has resulted.  相似文献

The trend of increasing health care costs over the past several years shows no signs of slowing down. While employers have attempted to address the issue with various cost-shifting and cost-sharing initiatives to relieve the burden, those attempts have often fallen short. In today's fiscally scrutinized benefits environment, the emphasis needs to be more strategic. The management of employee health and productivity needs to move to a more encompassing organizational view that addresses the most expensive drivers of these costs head-on, with prevention, education and employee responsibility as key tenets. Organizations that make the move--by implementing programs to maintain, improve and manage their population's health--will enjoy substantial cost savings and enhanced employee productivity.  相似文献

Abstract

While previous studies have investigated online health communities and health-seeking behaviours, less attention has been directed at the growing impact of the online fitness movement. This paper draws on the concept of biopedagogies to examine the messages transmitted within fitness culture on social networking sites (SNSs), and their role as a channel for health and fitness information. To explore this, a multi-method approach was conducted. The two methods included a netnography (online ethnography) and 22 semi-structured individual interviews with female participants aged 18–24 in Australia. The study suggests that online fitness use is becoming a popular leisure activity and source of health and fitness information. It reveals how SNSs are used as a platform to gather and teach ideas of health and fitness, and the manner in which textual and photographic online communication facilitates the social construction and transmission of this knowledge. Results indicated that although fitness accounts on SNSs offer differing notions to present alternative and competing realities, users predominantly chose to follow the normalised and dominant health discourses. Noteworthy, the onus is firmly placed on the individual within these health and fitness messages to adhere to norms of correct health practices and choices. This has connotations relevant to eHealth literacy.  相似文献

We identify the presence of shirking by Major League Baseball umpires during indefinite unpaid overtime, as defined by extra innings. In the presence of new information about expected game length, umpires exert biases in ball and strike calls consistent with opportunistically reducing the likelihood of working additional time. General implications with respect to the effectiveness of salaried workers during unpaid overtime hours are discussed.  相似文献

A major component of the United States Environmental Protection Agency's 112(r) Risk Management Program Rule is the evaluation and control of potential public exposures to toxic chemicals. The rule requires identification and evaluation of a worst case accidental toxic release scenario, but provides for the inclusion of passive mitigation systems in modeling the dispersion hazard zones that are to be communicated to the public. These passive mitigation systems can be taken into account in the consequence modeling if they will withstand the initiating event that causes the accidental release and function as intended. This paper discusses several passive mitigation systems that can be designed as an integral part of storage or processing of highly toxic chemicals. These include, but are not limited to, optimizing storage conditions, design of secondary containment, toxic vapor generation control, and enclosure design. The effectiveness of various passive mitigation systems is evaluated using consequence modeling for case studies involving highly toxic chemicals such as phosgene, chlorine, and ethylene oxide.  相似文献

Contingent knowledge workers will play an increasingly important role in organisational success as workers transition in and out of project‐based innovation teams with more frequency. Our research finds that collaborators in the contingent, high‐skill workforce face uncertainty challenges to their work that are unique from the independent, contingent professionals more often studied. The article proposes a theoretical framework of uncertainty to guide us in understanding collaborative contingent knowledge workers’ work experience. Interviews with postdoctoral researchers reveal four findings about the influence of these highly uncertain work environments on collaborative contingent knowledge workers – collaboration isolation, frustrated independence, performance anxiety and internalised blame. Perhaps most concerning is that the workers internalise the negative impacts as personal failings instead of recognising them as consequences of a poorly designed work environment. This study argues for the need to manage and mitigate different sources of uncertainty to avoid creating an unnecessary burden on contingent knowledge workers, and to enable a sustainable, contingent knowledge workforce.  相似文献

In this paper, we propose to identify the dependence structure that exists between returns on equity and commodity futures and its development over the past 20 years. The key point is that we do not impose any dependence structure, but let the data select it. To do so, we model the dependence between commodity (metal, agriculture and energy) and stock markets using a flexible approach that allows us to investigate whether the co-movement is: (i) symmetrical and frequent, (ii) (a) symmetrical and mostly present during extreme events and (iii) asymmetrical and mostly present during extreme events. We also allow for this dependence to be time-varying from January 1990 to February 2012. Our analysis uncovers three major stylised facts. First, we find that the dependence between commodity and stock markets is time-varying, symmetrical and occurs most of the time (as opposed to mostly during extreme events). Second, not allowing for time-varying parameters in the dependence distribution generates a bias towards an evidence of tail dependence. Similarly, considering only tail dependence may lead to false evidence of asymmetry. Third, a growing co-movement between industrial metals and equity markets is identified as early as 2003; this co-movement spreads to all commodity classes and becomes unambiguously stronger with the global financial crisis after Fall 2008.  相似文献
