This paper reports the findings from a recent study of nurse leavers at eight large hospitals in the National Health Service (NHS) of England and Wales. The study develops and extends an influential theory of employee turnover by describing how for some leavers a single, jarring event or shock triggers the decision to quit. By elaborating on the nature of shocks for this sample of 352 nurse leavers, the paper allows for improved understanding of nursing turnover and thus offers an example of relevant management research. The analysis of shock illustrates how conventional research methodologies can lead to a distorted picture of turnover. This has wider implications, both for any organization wishing to manage turnover effectively and for future research. The paper adds to the limited body of empirical analysis on actual leavers, thereby contributing to an ongoing methodological debate concerning the use of proxy variables. By highlighting flaws in the dominant methodology used to study turnover, the paper offers an example of management research that is also rigorous, and thus ‘pragmatic’. 相似文献

The networked age promises global digital cultures with flattened power relations, given the affordances of information and communication technologies to collapse distance, enable easier cross-country collaborations and create new opportunities for knowledge production and sharing. In the academic domains, indications are that knowledge patterns continue to reflect physically based geopolitical realities – where knowledge from the South is still peripheral while knowledge from the North still dominates in terms of all the conventional metrics. This study explores the potential role of digital affordances to challenge structural Northern bias and generates questions about knowledge production and dissemination in the climate change knowledge domain. It is framed by the field of scholarly communication within an African setting and by the emergent field of climate change which is fraught with debates and contestations, particularly regarding mitigation and adaptation. It draws on Southern theory which interrogates the global dynamics of knowledge production and dissemination. It explores the intersection of the discoverability and visibility of local climate change research methodologically from the outside in, through an experiment of searches for ‘climate change/South Africa’ and from the inside out by reviewing the online presence of one climate change group in a top-ranked African university. 相似文献

This paper offers a review of the literature on labour turnover in organizations. Initially, the importance of the subject area is established, as analyses of turnover are outlined and critiqued. This leads to a discussion of the various ways in which turnover and its consequences are measured. The potentially critical impact of turnover behaviour on organizational effectiveness is presented as justification for the need to model turnover, as a precursor to prediction and prevention. Key models from the literature of labour turnover are presented and critiqued. 相似文献

In Arizona, conflicts between homeowners and urban-dwelling javelina (Tayassu tajacu) continued to increase. Human-javelina conflicts often occurred when javelina responded to urban attractants and destroyed ornamental landscapes, injured pets, and frightened homeowners. This prompted initiation of a study during 1992–93 to develop recommendations to alleviate these conflicts. We captured, radio-collared, and located eight javelina from six herds to determine home ranges, habitat use, and activity patterns in Prescott, Arizona. Urban-dwelling javelina adjusted their home ranges, habitat use, and activity patterns to best use human-provided urban food, water, and cover resources. The most conspicuous of these adjustments was the increased nocturnal activity of urban-dwelling javelina to avoid human disturbances. Undeveloped land within or adjacent to Prescott provided javelina with daytime bedding areas and nighttime travel corridors. We determined that this issue was more a people problem than it was a javelina problem. Thus, strategies to resolve the conflicts must target homeowners. 相似文献

Abstract Objectives: The primary objective of this study was to characterize the prevalence of overweight/obesity, metabolic syndrome (MbS) and its criteria, and nutrient intakes of college-age men and women via a large-scale screening. Participants and Methods: From August 2005 to July 2008, 2,722 subjects were recruited for the ongoing, cross-sectional Young Adult Health Risk Screening Initiative project. Anthropometric, biochemical, clinical, and dietary data were collected. Results: Approximately one-half of men and more than one-quarter of women were overweight or obese. MbS was identified in 9.9% of men and 3.0% of women; 77% of men and 54% of women had at least 1 MbS criterion. Intakes of saturated fat, magnesium, and fiber, as well as body mass index and reported physical activity levels were related to MbS. Conclusions: Because of high rates of overweight/obesity and MbS, college-age adults are at risk for developing chronic diseases including diabetes mellitus and cardiovascular disease 相似文献

Fundamental problems remain with evidence‐based management. We argue that, rather than being addressed, these problems are treated as digressions. One explanation for this is an ongoing incoherence: the evidence‐based approach relegates narrative to a ghetto category of knowledge, but it is itself a narrative. Moreover, while this narrative is becoming more polished through repetition and selective assimilation of critique, it is also becoming simplified and less interesting. A Foucauldian, archaeological analysis accounts for this development by locating evidence‐based management in a broader historical context. This analysis shows how the roots of incoherence can be informed by older exchanges between evidence and narrative. 相似文献

We investigate estimation and testing procedures for the k-sample problem where each of the populations is subject to random truncation by possibly different but known truncation functions. Particular attention is focused on the two sample case which is motivated from the following important application. Neutrinos were detected from Supernova 1987A at two sites: the 1MB detector in Ohio (eight neutrinos observed) and the Kamiokande II detector in Japan (twelve observed). Each detector has different "trigger efficiencies", the chance of observing the flash of light produced by the neutrino knocking an electron loose from an atom. Thus, we have two independent samples of randomly truncated data. We assume a normal model for some power transformation of the data with the same power for each sample. We estimate the parameters of this distribution by maximum likelihood and find confidence regions for the parameters. A Monte Carlo study investigates the properties of the maximum likelihood estimators for this eutrino example.The simulations Show that approximate likelihood-based confidence regions provide coverages much closer to the nominal level than the regions based on asymptotic normal-theory. 相似文献
