Research about codes of corporate ethics has hitherto taken a hypothetical, correct meaning of codes for granted. The article
problematises the dichotomous categories intrinsic and subjective meanings of codes. I address the question if professionals
in finance accept codes of business. The particular mentality of stockbrokers and traders constructs the way they judge restrictions
such as company codes of ethics. While neglecting dimensions of ethics beyond known rules, brokers and traders distrust good
ethics as a possible end in itself. Many professionals in the financial market perceive efforts to integrate ethical reasoning
in work as only means for maximising business opportunities. 相似文献

AbstractObjective:The objective of this study was to compare clinician and patient measures of satisfaction with two pharmacological stress agents (PSA), regadenoson and dipyridamole, used in Single Photon Emission Computed Tomography (SPECT) Myocardial Perfusion Imaging (MPI).Methods:This observational study included patients who had undergone SPECT MPI with regadenoson or dipyridamole, as well as the clinician/clinical technologist who performed the test. Mean scores for individual item and domain scores of the main outcome measures were computed as well as the effect sizes (ES) of the mean difference in scores between treatment groups. Statistical significance of the mean item and domain score differences were assessed via Mann-Whitney tests.Main outcomes measures:Two self-report questionnaires which had beeb previously developed and validated: Patient Satisfaction/Preference Questionnaire (PSPQ) and Clinician Satisfaction/Preference Questionnaire (CSPQ).Results:A total of 87 patients (68 received regadenoson, 19 received dipyridamole) and nine clinicians/clinical technologists took part in the study. Patients had a mean age of 66.8?±?12.2 years, and 56.3% were male. Compared to dipyridamole, use of regadenoson was associated with greater clinician satisfaction on all items and domains of the CSPQ (p?<?0.001 for all comparisons). Among patients, regadenoson was associated with less bother and greater satisfaction than dipyridamole for all items on the PSPQ. These patients reported less stinging at the injection site (ES?=??0.66) and less nervousness during injection (ES?=??0.60). The PSPQ found that regadenoson patients were more satisfied with their PSA than dipyridamole patients in all areas.Limitations:This study utilized a relatively small sample size of dipyridamole patients and lacked an adenosine group. A broader sampling of professionals would also help demonstrate generalizability.Conclusion:Both patients and clinicians reported higher satisfaction with regadenoson compared to dipyridamole for SPECT-MPI. Clinicians were particularly satisfied with the preparation and administration aspects of the drug, while patients rated it highly on convenience and reduced incidence of side-effects. 相似文献

The complex and changing environment of the hospitality industry presents a never ending array of stimuli, pressures and demands which can become sources of stress for hotel supervisors. A focus on the identification of current and potential stressors in organizations, and the development of strategies which individuals and management may use to manage and reduce stress effectively, is imperative. This study is to investigate the perceived level of stress of hotel supervisors, to establish frequency of the use of various coping strategies, and to determine the burnout rate. This study also empirically examines the relationships among stress, coping strategies, and job burnout. A convenient sample of hotel supervisors of large hotels in Taiwan was selected. The return of 298 questionnaires represented 74.5% of the total supervisors surveyed. The study findings suggest that the major job stress of hotel supervisors originates from task characteristic and workload. Moreover, a direct action coping strategy may allow one to perceive the situations as opportunities and may, in turn, contribute to reduce job stress. Furthermore, hotel supervisors experience a lower level of burnout if they apply more direct action strategies in coping with the pressures of their job. The results of this study can be used as part of guidelines including what should be considered to reduce job stress and burnout in the work environment. 相似文献

帽梁施工采用无支架法施工相对满堂支架法施工而言,具有施工简便,对地面承载力无要求,节约大量钢管,降低施工成本,缩短工期等优点。文章针对洛湛铁路旺甫1号三线大桥设计出穿心棒无支架法施工帽梁的支撑系统方案,成功地解决了三线大桥因帽梁砼重量大、跨度长而致使常用材料不适合做承托梁的问题,并对支撑系统进行了受力检算。 相似文献

采用挂篮施工的连续刚构边跨现浇段的支架形式多种多样,其设计目的是施工简便、安全牢固、确保质量及节约成本。在遂渝二线铁路薛家坝涪江左线特大桥连续刚构梁边跨现浇段施工时采用型钢吊架支撑,吊架分别利用原施工悬浇节段的挂篮及在墩顶预埋工字钢作支承点。吊架施工现浇段不仅结构简单、施工方便,而且在安全、质量及效益方面均取得了很好的效果。文章对型钢吊架的设计、施工方法进行了详细介绍,并对吊架进行了受力分析及验算,验证了方案的可行性,为以后同类桥型的施工提供参考。 相似文献

固井工程是一项应用工程,是建井过程中的重要环节,它直接影响钻井周期和建井成本,以及油田开发方案的实施。深井、超深井的井下地质条件非常复杂,对固井质量有许多不利的因素,在井下条件确定的情况下,决定性的因素是环空流动的壁面剪应力,它是影响顶替效率的主要因素。 相似文献
