Elevators are mechanical transportation devices used to move vertically between different levels of a building. When first developed, elevators lacked the safety features. When safety mechanisms were developed, elevators became a common feature of multistory buildings. Despite their well-regarded safety record, elevators are not without the potential for danger of injury or death. Persons at-risk for elevator-related death include maintenance and construction workers, other employees, and those who are prone to risky behavior. Deaths may be related to asphyxia, blunt force, avulsion injuries, and various forms of environmental trauma. In this review, we report on 48 elevator-related deaths that occurred in nine different medicolegal death investigation jurisdictions within the United States over an approximately 30-year period. The data represents a cross-section of the different types of elevator-related deaths that may be encountered. The review also presents an overview of preventive strategies for the purpose of avoiding future elevator-related fatalities. 相似文献

This paper examines the process of technology transfer and associated learning effects experienced by the Greek telecommunication equipment manufacturer INTRAKOM as a result of its involvement in public procurement processes and the technological shift towards software-driven digital switching and transmission systems. Drawing upon the role of Government procurement as an instrument for industrial policy and the learning potential of a technology transfer process, the paper argues that the Public sector's industrial policy considerations, exercised through the procurement practices of the Greek Public Telecommunication Operator (OTE), as well as INTRAKOM's own timely focus in establishing a long-term collaboration agreement with a leading international vendor (ERICSSON) played a catalytic role in the accumulation of domestic capabilities in the manufacturing of selected telecommunication equipment products. 相似文献

While models of organizational strategy saturate private sector research, public sector research lags behind. The model created by Boyne and Walker (2004) is an exception. The main objective of this study is to operationalize this model using a unique data set from the US transit industry. Through a survey of 103 local transit agencies, we developed separate strategy profiles for each agency that help us answer important questions about organizational strategy. We find that not only do the organizations adopt a mix of strategic stances through the action areas; they also have distinct profiles, which vary greatly between agencies. 相似文献

The European Union (EU) has fortified its external borders using a number of measures including the creation of new institutions and networks such as FRONTEX and EUROSUR. In non-EU countries such as Turkey, border security is being reorganized with EU support and cooperation. By combining the literature on EU actorness and neo-functionalism, I provide a theoretical toolkit to critically unpack these new developments through conceptualizing multiple dimensions of what I call functional actorness. The contribution analyzes how the functional transformation of EU and Turkish border security has produced a number of side effects which are critically appraised. 相似文献

Needs-based grant programs are budgeting systems that tie grant dollars to the needs of the grantees as determined by objective indicators. Although performance improvement is not an explicit goal of such grants, the associated awards could work as incentives for grantees to meet the grant criteria. In other words, grantees seek to improve their performance to fulfill the criteria, even though the grant-makers intend such grants to support the existing operational needs of the grantees. This study tests these assertions in the context of the small transit intensive cities (STIC) grant that was established as a needs-based grant system by the federal government to support small local transit agencies operating with unusually high service demands. This study argues that these systems would have a stronger impact on indicators over which grantees have more control. This study tests these assertions using a difference-in-differences analysis of 290 transit agencies over 17 years. The findings show that STIC is effective in improving grantee performance, at least on the indicators which are more amenable to control. 相似文献

Residential fires are a significant cause for morbidity and mortality in the United States. Death is often the result of soot and smoke inhalation causing carbon monoxide (CO) toxicity. The approximate lethal level of carboxyhemoglobin (COHb) in healthy adults has been well described. However, a significant number of medical examiner cases involve infirmed decedents, often elderly, with complex cardiovascular disease burdens. It is well known that death in these cases will occur at sublethal levels of COHb; however, increased lethality has been largely documented via anecdotal experience and lacks quantification. Fifty-five cases were identified where death resulted from smoke and soot inhalation suffered in a residential fire. The control group, with no cardiovascular disease, had an age-adjusted mean COHb level of 61.6% at the time of death. Presence of hypertensive cardiovascular disease showed a 30% reduction in COHb (age-adjusted mean 43.2%), atherosclerotic disease showed a 33% reduction (age-adjusted mean 41.5%), and combined disease presentation accounted for 41% reduction (age-adjusted mean 36.3%). When controlling for age, atherosclerotic and hypertensive cardiovascular diseases were each associated with statistically significant decreases in COHb (p < 0.01). Increasing age was associated with decreased COHb levels at 2.8% per 10 years of life (p < 0.01), even when modeled with hypertensive and atherosclerotic disease. These findings carry important public health significance, as well as practical significance for the medical examiner when interpreting COHb levels in cases of suspected deaths due to smoke and soot inhalation. 相似文献
