We investigate the efficacy of a multisectoral road safety campaign initiated at Luang Namtha Provincial Hospital (LNPH), North-Laos. Road safety days (RSD) with helmet promotion were organised prior to the Lao and International New Year 2007. Motorbike helmet protectiveness was demonstrated by dropping peeled versus unpeeled coconuts from 6-m high sticks simulating city speed-limit (40?km/h). The primary outcome was the number of road traffic injuries (RTI) needing admission (severe RTI) before and after the first RSD. Secondary outcomes were helmet usage, total RTI, hospital staff's behavioural changes and law enforcement. Neighbouring Bokeo Provincial Hospital (BPH) had no intervention. Severe RTI dropped by 34.7% within 12 months (from 449 to 293, p?≤?0.0001, BPH +123% [from 88 to 196]). Total RTI increased by 10.8% (from 772 to 855, p?=?0.0396, BPH +260.8% [from 186 to 671]). Police started the law enforcement right after the RSD. Helmet use increased from 11.2 to 42.5% (p?相似文献

Abstract

Based on the social exchange theory and on ageing and life-span theories, this paper aims to examine: (1) the relationships between perceived availability and use of HRM practices, and employee outcomes (i.e. work engagement and employability); and (2) how employee age moderates these relationships. Using a sample of Nmaximum = 1589 employees, correlational analyses and multiple hierarchical regression analyses were conducted. First, confirming our hypotheses, results showed predominantly positive relationships between work engagement and both perceived availability and use of development HRM practices, such as HRM practices related to learning, development, and incorporating new tasks. The study outcomes opposed, however, our hypotheses with predominantly negative relationships between work engagement and perceived availability and use of maintenance HRM practices. Predominantly positive relationships were furthermore found, as was hypothesized, between employability and perceived availability and use of development as well as maintenance HRM practices. Generally speaking, these results were not more pronounced for any of the age groups. That is, age appeared to not play any significant moderating role. Research limitations, implications for practice and directions for future work are also discussed.  相似文献

Federal Open Market Committee (FOMC) policymakers have published macroeconomic forecasts since 1979 and we examine the effects of FOMC inflation forecasts using a structural VAR model. First, we assess whether they influence private inflation expectations. Second, we investigate the underlying mechanism at work and whether they convey policy signals. We provide original evidence that FOMC inflation forecasts influence private ones. We also find that the influencing effect of FOMC forecasts does not come through current Fed rate changes, that FOMC forecasts affect private expectations in a different way than current policy decisions, and that FOMC forecasts are informative about future Fed rate movements.  相似文献

A 1999 study looking at the research relationships within and between the disciplines of hospitality and tourism is revisited. When compared to the 1999 study, the current study reveals that there is more within-discipline citing, suggesting that both the hospitality and tourism academic areas are maturing, and not relying as heavily on other disciplines. Further analysis of the citations outside hospitality is done to elicit a more in-depth picture of where hospitality and tourism citations are coming from. Implications are discussed.  相似文献
