An empirical analysis of the behavioral ecology of slip, trip, and fall accidents in grocery stores and shopping malls is presented. The store data set comprised 36 consecutive months of data collected from a chain of grocery stores in the Midwestern USA and the mall data set included 24 consecutive months of data collected from 22 malls across the continental USA, with a concentration in the southern region. Analyses showed that the majority of the slip, trip and fall accidents occurred on the inside of the establishments, on the same level, and resulted from a water or liquid spill or food item on the floor. Design deficiencies accounted for the least amount of occurrences and cost of the accidents, while housekeeping and inspection deficiencies accounted for the bulk of the accidents. Data‐based recommendations for slip, trip and fall injury‐prevention strategies in these public places, focusing on management action, are offered.  相似文献

Some thirty years ago, politicians in Anglo‐American democracies introduced a series of measures designed to give them the upper hand in shaping public policy and to push senior public servants to become better managers. The government of Canada was no exception. Politicians essentially decided to look to the private sector to improve public sector management. The efforts have failed, have been costly to taxpayers, and have knocked the federal public service off its moorings. The article argues that the public service needs to rediscover its roots and walk away from simple assumptions tied to economic self‐interest and deductive models and from the mantra that reforms inspired by the private sector can drive productive change in the public sector.  相似文献

Why should research institutions engage in technology transfer? Some say it is about the money. Others say it is about public service and benefit. In the end, we measure what we value. If we only measure money, we confound the non-profit mission of the research institution. If we measure economic impact, the non-profit technology transfer office is often expected to become the economic developer, confusing real estate and business development with technology transfer, often without additional funding. These mission strains lead to overwhelm, fatigue, service shortcomings, and unhappy customers across all classes of stakeholders. This article suggests a return to center for academic technology transfer offices (TTOs) by focusing on a most important question for drivers of our present global knowledge economy––how well does a TTO facilitate access to knowledge protected by intellectual property of its faculty and institution? This article proposes that academic technology transfer performance should be evaluated by how well a TTO avails access to knowledge. Given that performance measures are also referred to as “metrics,” we call this preferred outcomes orientation an access metric.  相似文献

Using a national survey of law enforcement agencies, this study (1) measured agencies' ability to fill sworn positions, (2) identified the strategies used to attract and hire females and minorities, (3) measured agencies' success in filling sworn positions with females and minorities, and (4) measured through negative binomial regression the impact of agency strategies and agency/jurisdiction characteristics on levels of female and minority applications and hires. The results indicated great variation in agencies' ability to fill sworn positions and fill them with females and minorities and considerable variation in the extent to which mechanisms are used to attract females and minorities to policing. Just one in five agencies has adopted targeted recruitment strategies for women and minorities. Agency success in attracting the applications of and hiring females and minorities varies greatly. The multivariate analyses indicate that recruiting budget and targeting minorities and women do positively affect hiring.  相似文献

As the effects of climate change are felt, affected parties will seek redress in the legal system. Numerous suits have already been filed and this may only be the beginning of a trend. One type of suit that has not yet been filed is the natural resource damage (NRD) claim under CERCLA. While it is unlikely that climate change-based NRD claims could succeed under current law, it may only be a matter of time before they are brought. With the present legal landscape in mind, this article examines statutory requirements under CERCLA to bring a climate change related NRD claim.  相似文献
