Abstract

To date management of fatigue in professional drivers has largely focused on strategies that limit the amount of time spent on the job. These approaches have, however, not taken into account the well-documented effect of time of day. Consequently, the likely impact of the pattern and timing of work and rest has received little attention. The results revealed that the group of drivers who did the shortest trips and worked the shortest weekly hours were the lowest reporters of fatigue, although longer hours were not always associated with the highest reporting of fatigue. In contrast, the shortest working hours were associated with earliest onset of fatigue. For all drivers, the influence of circadian rhythms was evident in the occurrence of fatigue, with better management of the problem evident among drivers who were able to arrange the timing of rest to more closely coincide with periods of fatigue. Thus, time of day appeared to be a more important influence in determining effective rest than did period of work. These findings raise questions about the validity of the assumption underlying work hour regulations for long-distance drivers which, currently, are universally based on duration of work.  相似文献

Abstract

Workplace accidents and violence are both potential sources of employee injuries that have been dealt with in entirely separate literatures. In this study we adapted the concept of safety climate from the accident/injury literature to violence in developing the concept of perceived violence climate. A scale was developed to assess perceived violence climate, including items about management attention, concern, and policies designed to keep employees safe from violence. Data were collected from a sample of 198 nurses from a US Hospital. Perceived violence climate was found to correlate significantly with both physical violence and verbal aggression experienced by the nurses, injury from violence, and perceptions of workplace danger. Furthermore, regression analyses showed that climate explained additional variance in psychological strain and perceptions of danger over experienced violence. These results have implications for interventions aimed at producing a good perceived violence climate in order to reduce the incidence of violence and aggression within an organization.  相似文献

Urinary incontinence (UI) is a common and stigmatizing problem faced by long-term care (LTC) residents. It is typically addressed by medical professionals, with social work rarely involved. The purpose of this article is to illustrate how social workers can address the psychosocial implications of UI while working with residents and their family members as part of an interdisciplinary team. Using a case example and the NASW objectives for LTC, recommendations on how the role of the LTC social workers can be expanded to better address both the needs of residents, families, and the larger LTC system are provided.  相似文献

Over two billion dollars was awarded by the U.S. Department of Health and Human Services (HHS) in research funding from 2010 to March 2012 to institutions receiving a grade of "C," "D," or "F" on their conflict of interest policies, as determined by the American Medical Student Association's scorecard on conflict of interest policies. More institutional oversight is needed with regard to assuring conflict of interest policies at U.S. research institutions are adequate. As stewards of public funds, HHS should require a minimum standard which institutional conflict of interest policies should meet, beyond current regulatory requirements, before granting funding.  相似文献

The issue of coopetition, the coexistence of cooperation and competition, has recently come to the fore in the strategic management field. Previous coopetition research has focused on the intra‐organizational level, inter‐organizational level and triad level, but less attention has been paid to coopetition at the network level. The purpose of this paper is to address the coexistence of competition and cooperation between networks, and to depict how networks with different structures interact with each other. Drawing from a detailed case study of two healthcare networks in Taiwan, we demonstrate how they first initiated competition, followed by cooperation and then coopetition. From our analysis of this example of network coopetition, we develop three propositions that address the forces driving competition and cooperation and the different structures that allow competition and cooperation to coexist. We found that two organizations will compete and cooperate simultaneously when each organization has complementary but distinctly different sets of resources and when the field of competition is distinctly separate from the field of cooperation. In addition, two networks will find it easier to balance competition and cooperation when each network has compatible but distinctly different structures. We argue that the simultaneous existence of cooperation and competition is not dependent on closeness to the customer, as previously suggested in the literature, but on the balance between the forces for cooperation and for competition. We suggest from this research that networks can maintain the balance between competition and cooperation when they act using different structures. Finally, we discuss the implications of the value of competition and then coopetition at multiple levels of analysis and the implications for future research from a practical perspective.  相似文献

This article uses a variant of Geweke's (1982) linear feedback measure to test common characterizations of monetary neutrality implicit in classes of relative price models. The neutrality properties are defined in terms of relative price changes' response to monetary policy shocks in a system including average price changes, an interest rate, and industrial production growth. The magnitude and patterns of monetary feedback found in U.S. relative price data provide no support for any of the structurally neutral models.  相似文献
