This article adapts Actor Network Theory to illustrate the construction of heroes and their abandonment. It focuses more specifically on the rise and fall of an iconic New Zealand private training enterprise, Carich, and its founding entrepreneur Caron Taurima. Drawing on media, web sources and interviews, the study reflects on the uncritical way heroes are constructed and makes comparisons with the story of Joan of Arc. It shows how the notion of ‘Carich‐as‐a‐successful‐business’ was encouraged and developed by human and non‐human actors, how revenues were inflated, and how the business founder’s personal charisma superseded hard financial questions. The article problematizes the roles of various actors, particularly hero‐seeking media, politically‐correct Crown agencies, and those supposedly objective umpires of business acumen who offer national awards to ‘outstanding’ entrepreneurs.  相似文献

Axiomatic theory construction was used in this study to analyze the likelihood of participation in premarital sexual intercourse by college women. The sample consisted of 754 never-married female students enrolled in a midwestern, residential university who responded to a sexual attitudes and behavior survey. Forty-eight empirical propositions concerning premarital sexual intercourse were tested, nineteen of which were found to be statistically significant. Three derived propositions were reformulated from these findings, which in turn were utilized to develop two middle-range theories: commitment theory and cultural milieu theory. These theories clearly demonstrate the role of changing personal and societal attitudes toward sexuality and perceived partner commitment in the decision to become sexually active.  相似文献

Effective measurement of information system (IS) success continues to be a top concern for both practitioners and researchers. Labeled the “productivity paradox”, previous attempts to quantify the benefits of IS have often resulted in inconclusive or inconsistent results. The present study contributes to IS success research through the development and empirical testing of a process-oriented model of IS success. Using an operational perspective and combining primary and secondary measures, this study examines the influence of lower-level intangible IS and information technology (IT) benefits on higher-level financial measures. Additionally, we introduce IS plan quality as an antecedent to the model's input variables. Primary survey data from CIOs of primarily Fortune 2000 size firms are combined with secondary data, total operational cost, from Compustat to facilitate the examination of the IS benefits. This study also addresses shortcomings cited in other studies that might have contributed to the productivity paradox by including control variables in the model, defining a research perspective—the operational success perspective—and clearly articulating the level of analysis as the organizational level. The results supported a process-oriented view of the benefits from IS and showed how the effects of IS along a path can lead to better organizational performance, in this case, lower overall costs. These results are discussed and future research implications are presented.  相似文献

Hurricane wind risk in a region changes over time due to changes in the number, type, locations, vulnerability, and value of buildings. A model was developed to quantitatively estimate changes over time in hurricane wind risk to wood-frame houses (defined in terms of potential for direct economic loss), and to estimate how different factors, such as building code changes and population growth, contribute to that change. The model, which is implemented in a simulation, produces a probability distribution of direct economic losses for each census tract in the study region at each time step in the specified time horizon. By changing parameter values and rerunning the analysis, the effects of different changes in the built environment on the hurricane risk trends can be estimated and the relative effectiveness of hypothetical mitigation strategies can be evaluated. Using a case study application for wood-frame houses in selected counties in North Carolina from 2000 to 2020, this article demonstrates how the hurricane wind risk forecasting model can be used: (1) to provide insight into the dynamics of regional hurricane wind risk-the total change in risk over time and the relative contribution of different factors to that change, and (2) to support mitigation planning. Insights from the case study include, for example, that the many factors contributing to hurricane wind risk for wood-frame houses interact in a way that is difficult to predict a priori, and that in the case study, the reduction in hurricane losses due to vulnerability changes (e.g., building code changes) is approximately equal to the increase in losses due to building inventory growth. The potential for the model to support risk communication is also discussed.  相似文献

In 2001, the U.S. Environmental Protection Agency derived a reference dose (RfD) for methylmercury, which is a daily intake that is likely to be without appreciable risk of deleterious effects during a lifetime. This derivation used a series of benchmark dose (BMD) analyses provided by a National Research Council (NRC) panel convened to assess the health effects of methylmercury. Analyses were performed for a number of endpoints from three large longitudinal cohort studies of the neuropsychological consequences of in utero exposure to methylmercury: the Faroe Islands, Seychelles Islands, and New Zealand studies. Adverse effects were identified in the Faroe Islands and New Zealand studies, but not in the Seychelles Islands. The NRC also performed an integrative analysis of all three studies. The EPA applied a total uncertainty factor (UF) of 10 for intrahuman toxicokinetic and toxicodynamic variability and uncertainty. Dose conversion from cord blood mercury concentrations to maternal methylmercury intake was performed using a one-compartment model. Derivation of potential RfDs from a number of endpoints from the Faroe Islands study converged on 0.1 microg/kg/day, as did the integrative analysis of all three studies. EPA identified several areas for which further information or analyses is needed. Perhaps the most immediately relevant is the ratio of cord:maternal blood mercury concentration, as well as the variability around this ratio. EPA assumed in its dose conversion that the ratio was 1.0; however, available data suggest it is perhaps 1.5-2.0. Verification of a deviation from unity presumably would be translated directly into comparable reduction in the RfD. Other areas that EPA identified as significant areas requiring further attention are cardiovascular consequences of methylmercury exposure and delayed neurotoxicity during aging as a result of previous developmental or adult exposure.  相似文献

In the wake of a number of high‐profile cases of the abuse of children and young people in residential child care, there have been repeated calls for the improvement of recruitment and selection of residential child care staff. This paper describes the findings from a survey, undertaken in 2005, of operational and human resource managers who have responsibility for the recruitment and selection of residential child care staff in the voluntary and statutory sectors in Scotland. This research was commissioned by the Scottish Executive to identify which elements of safer recruitment procedures had been implemented following the countrywide launch of a Toolkit for Safer Recruitment Practice in 2001. Research findings show that although local authorities were more likely than voluntary organisations to have gone some way toward implementing safer recruitment procedures, the recruitment process lacked rigour and commitment to safer procedures in some organisations. The article discusses the current barriers to the introduction of safer recruitment methods and proposes some possible solutions for the future. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Objective and Participants: The author conducted this study to determine college health education and promotion practitioners' perceived continuing education needs and perceived job relevance in relation to national health education responsibilities and competencies. Methods: In Spring 2006, the author invited college health education and promotion professionals to participate in an online survey, using 3 listservs. Of 276 individuals visiting the Web site, 141 participants completed the survey (51%). Participants rated their perceived training needs and job relevance for the 35 National Commission for Health Education Credentialing (NCHEC) competencies as well as preferred training formats. Results: Participants identified the following competencies as those in which they needed additional training: designing data-collection instruments, securing fiscal resources, interpreting evaluation and research results, carrying out evaluation and research plans, and developing plans for evaluation and research. They identified the following competencies as being the most relevant to their jobs: demonstrating a variety of skills in delivering strategies, interventions, and programs; using a variety of methods to implement strategies, interventions, and programs; initiating a plan of action; and using health-related information resources. The most preferred methods of obtaining additional continuing education were attending the American College Health Association annual meeting (67%) and completing home self-study print materials (67%). Conclusions: Collegiate professional organizations should offer a variety of continuing education opportunities centering on NCHEC competencies, specifically those perceived as needed by study participants.  相似文献

ABSTRACT

Through nonrandom purposive sampling, this article examines the ways three Catholic agencies offered bushfire recovery assistance after the 2009 bushfires in the Australian state of Victoria. Participants from Catholic welfare agencies (29), local and state government (8), international recovery agencies (2), and others such as clergy, church, and medical (6) were selected, and senior managers, middle managers, and workers on the ground were interviewed up to 3 times during a 3-year period. The forty-five people were interviewed a total of 74 times. Study results illustrate the importance of adaptability, flexibility, and preplanning as the core of recovery assistance. Linking with local and state government disaster management plans and developing mechanisms to inform other groups as to the services that new agencies could provide were essential for filling gaps in services and establishing cooperative ventures. Recommendations are provided but more research is needed on how other agencies can benefit from the knowledge gained in this study.  相似文献
