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

构建了包括劳动密集型产业和资本密集型产业的政府目标函数,利用2005—2012年中国省际面板数据,测算了劳动密集型产业和资本密集型产业的权重区间。研究结果表明:中国政府目标函数中资本密集产业部门的权重介于0.564~0.623之间,资本密集型产业部门的权重显著大于劳动密集型产业部门;政府更重视资本密集型产业部门的福利。 相似文献

从行业层面和企业层面实证研究了银行信贷选择对行业和企业发展的影响。结果发现:在行业层面,银行偏好于固定资产比率较高的行业,因此在信贷资源较为紧张的地区,固定资产比率较高的行业会发展得较好,可见长期内银行选择会影响一个地区的产业结构;在公司层面,银行偏好于行业中固定资产比率较高的企业,而企业为了获得信贷资源也会调整其发展策略,倾向于积累固定资产。指出:中国应该大力发展非银行融资渠道,减弱金融系统对经济发展的扭曲。 相似文献

In this paper, we examine how the geometry underlying revealed preference determines the set of preferences that can be revealed by choices. Specifically, given an arbitrary binary relation defined on a finite set, we ask if and when there exists a data set which can generate the given relation through revealed preference. We show that the dimension of the consumption space affects the set of revealed preference relations. If the consumption space has more goods than observations, any revealed preference relation can arise. Conversely, if the consumption space has low dimension relative to the number of observations, then there exist both rational and irrational preference relations that can never be revealed by choices. 相似文献

We identify a natural counterpart of the standard GARP for demand data in which goods are all indivisible. We show that the new axiom (DARP, for “discrete axiom of revealed preference”) is necessary and sufficient for the rationalization of the data by a well-behaved utility function. Our results complement the main finding of Polisson and Quah (2013), who rather minimally modify the original consumer problem with indivisible goods so that the standard GARP still applies. 相似文献

This study examines the influences of airline global alliances on the purchase intention of international air passengers in Taiwan. The findings indicate positive relationships between global airline alliances, brand equity, brand preference and purchase intention with a moderation effect of involvement impacting on the relationship between global airline alliances and brand equity, and the relationship between brand preferences and purchase intention. In particular, for highly involved passengers, the effect of global airline alliances on brand equity, and brand preference on purchase intention, is significant. 相似文献

This paper integrates two key approaches to the representation of incomplete preferences over lotteries. The main result strengthens the conclusion of the expected multi-utility theorem in Dubra, Maccheroni, and Ok (2004) by ensuring that all utility indices involved are Aumann utilities (i.e., yield a strictly increasing expectation). The advantages of the method are demonstrated by parametrizing maximal elements and by providing a novel characterization of Aumann utilities. 相似文献

Although many companies in the hotel industry aim to pursue more sustainable and socially responsible practices, the present literature shows mixed results with regard to tourist reactions to such moves, especially for the service quality perception impacted by implemented green practices and the willingness to pay more for such actions. Unlike previous research examining tourists’ preferences for separate green hotel attributes, this study identifies the determinants of tourists’ choice of green hotel attributes. Additionally, the study measures the willingness to pay (WTP) for such services, in the context of the Taiwanese market, using the stated preference of combined green hotel attribute scenarios. A multinomial logit (MNL) model is employed to estimate the relative influence of behavioral and facility attributes on choice behavior. Furthermore, the study examines determinants influencing respondents’ choice of green hotel attributes. A latent variable class model (LVCM) approach is applied in the estimation of the unobserved heterogeneity, and a total of 390 valid respondents were used in the analysis. The empirical MNL results indicate that while tourists prefer luxury rooms and the provision of personal toiletries, they are also willing to accept reduced service quality. Additionally, sex, income, and age have significant influences on tourist choice behavior. The results of the LVCM model demonstrate that respondents with high levels of the green consumption trait are more likely to choose hotels that have a greater number of environmentally friendly attributes. The implicit amount that tourists are willing to pay for room quality is around US$13, for the provision of personal toiletries is about US$22, and for service quality is US$12, but they also require a discount of approximately US$11 in order to accept the common practices of green hotels. This study is useful in providing the hotel industry and government with quantitative information that can be used to develop and implement better green hotel policies. 相似文献

The paper considers arguments of Robertson (1938) and Asimakopulos (1983) that the Keynesian multiplier expansion of output may be constrained by debt implicitly incurred in the financing of autonomous investment necessary to start the multiplier process. The task of this essay is to show that within the ‘short-period’ and static analytical framework of Keynes, this line of reasoning regarding the adverse effects of debt on multiplier-induced expansions of output is unwarranted. Nevertheless it is concluded that if the Keynesian framework is abandoned in favour of a dynamic framework in the manner of a steady trend rate of growth - a choice dependent on how one conceives of the economy, as inherently static or dynamic - then such arguments have troubling implications. In particular, the dependence of Keynes's approach on credit and hence debt forges links between ‘short-periods' whose distinctness from one another is crucial to Keynes's result. 相似文献
