When will customers care about service failures that happened to strangers? The role of personal similarity and regulatory focus and its implication on service evaluation

This paper examines an interesting research question: how does a service failure that happen to a stranger customer influence an observing customer's service evaluation? Drawing on the defensive attribution theory and regulatory focus theory, we argue that an observing customer will attribute more (vs. less) blame to the company if the customer involved in the undesirable incident is personally similar (vs. not similar) to him/her. These attributions, in turn, will influence the observing customers to form a negative evaluation on service quality of the company. More importantly, a prevention-focused tendency will intensify the negative impact of personal similarity on service evaluation. Results from two experiments confirmed the hypotheses.     

Determinants of Deep Integration: Examining Socio-political Factors

This research has three main aims: firstly, to empirically analyse the determinants of different levels of integration by re-examining the evidence presented by Baier and Bergstrand (Journal of International Economics 64(1):29–63, 2004) in the JIE 64 (1); secondly, to analyse the importance of additional factors, in particular socio-political factors; and thirdly, to analyse the dynamics of the EU integration process. The results show that although economic and geographical factors are the most important explanatory factors for the probability of regional integration agreement formation or enhancement, socio-political variables also contribute to explain the formation of regional integration agreements. Democracies and countries with a higher level of economic freedom are more likely to form or enhance RIAs.

危险的赵

谈论一个人或一件陌生的作品可能经常要冒着过度阐释的危险,好在"工作坊"这个栏目更多的还是为了呈现一个艺术家阶段性的工作状态。赵赵很少跟人解释自己的作品,我们所了解最多的只是作者对作品制作过程的一般性描述,在另外两篇与秦思源、王兴伟的谈话也能看出来,对于艺术赵赵多半都是隐而不发的,对于生活方面却是津津乐道。或许这正是他的别有用心之     

Healthcare resource utilization among commercially insured patients with cold agglutinin disease in the United States

Abstract

Aims: Cold agglutinin disease (CAD) is a rare subtype of autoimmune hemolytic anemia associated with increased thromboembolism risk and early mortality. Healthcare resource utilization (HRU) in CAD has not been reported. We aimed to compare HRU of patients with CAD with a matched non-CAD cohort in the United States.

Materials and methods: Patients with CAD were identified from 2006 to 2016 in the Optum-Humedica database using CAD terms in clinical notes and hematologist review. Patients were required to have Integrated Delivery Network records and ≥6 months’ follow-up before and after the first CAD mention date (index date). Patients with CAD were matched to a non-CAD cohort based on demographics. Multivariate analyses assessed inpatient hospitalizations, outpatient visits, emergency room visits, and transfusion use between cohorts 6 months before and 12 months after the index date.

Results: Of 814 patients with CAD, 410 met inclusion criteria and were matched to 3,390 patients without CAD. Mean age of patients with CAD was 68.0 years; approximately 62% were female. In the 12 months after the index date, mean inpatient hospitalizations (0.83 vs. 0.25), outpatient visits (17.26 vs. 6.77), emergency room visits (0.55 vs. 0.32), and transfusion days (1.05 vs. 0.05) were higher for patients with CAD than the matched non-CAD cohort (all p?<?.0001). Similarly, in the 6 months before the index date, patients with CAD had higher HRU than matched patients without CAD for all measures evaluated.

Limitations: Results of this study are based on patient information from the Optum-Humedica database, which is limited to commercially insured patients and may not represent the overall CAD population.

Conclusions: CAD places a substantial burden on patients and healthcare systems. In addition, the high HRU for patients with CAD observed in the 6 months before diagnosis indicates that disease awareness and better diagnostic practices may be needed.

Corporate Carbon Strategies in Responding to Climate Change

With climate change emerging as one of the most important issues affecting the business circle, companies have begun considering the carbon issue in their overall strategic positioning. However, few studies have examined the corporate carbon strategies in developing and advanced developing countries, where climate change regulation is extensive and market uncertainty is relatively high. In addition, there has been growing interest among researchers and practitioners concerning the relationship between the carbon strategy and firm performance. This paper presents a framework for identifying the corporate carbon strategy. The cluster analysis of 241 Korean companies indicates six types of corporate carbon strategy: ‘wait‐and‐see observer’, ‘cautious reducer’, ‘product enhancer’, ‘all‐round enhancer’, ‘emergent explorer’ and ‘all‐round explorer’. This study empirically examines whether there are differences between these carbon strategy types in terms of the sector, firm size and firm performance. The results indicate a significant relationship between a firm's carbon strategy and its sector and size but a significant relationship between the carbon strategy and firm performance is not confirmed.
