“I don’t Care that People don’t Like What I Do” – Business Codes Viewed as Invisible or Visible Restrictions

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.     

Patient- and clinician-reported satisfaction with pharmacological stress agents for single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI)

Abstract

Objective:

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.     

荣地水电站增机扩容工程压力钢管的结构设计

荣地水电站增机扩容工程原发电引水系统主要为总长为2663 m的隧洞，由于隧洞竖井至原钢衬段前的钢筋混凝土衬砌施工质量较差，达不到结构安全运行的要求，因此需对原发电引水系统进行加固处理，经方案比选后，采用竖井段进行埋管回填混凝土加固+下平洞内铺设明钢管的方式进行加固处理，并相应对钢管进行结构设计。     

Job stress,coping strategies,and burnout among hotel industry supervisors in Taiwan

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.
