不同剂型硝苯地平治疗高血压的药物经济学评价

目的评价抗高血压药硝苯地平临床常用三种不同剂型治疗高血压的临床效果和经济效益。方法选择90例高血压病患者随机分为三组,每组30例,分别口服硝苯地平普通片、缓释片和控释片治疗,并进行药物经济学分析。结果服药8周后各组患者血压均有明显下降,其中普通片、缓释片和控释片治疗高血压总有效率分别为93.33%、93.33%、96.66%,不良反应发生率分别为10.0%、6.6%、0.0%,成本-效果比分别为0.02、0.40、2.96,控释片相对于普通片的增量成本-效果比为85.43。结论硝苯地平缓释片虽其消费成本不是最低,但服法简单,副作用较少,综合评价是硝苯地平临床常用三种剂型治疗高血压的最佳剂型,特别适用于基层医院。

How perceived empowerment HR practices influence work engagement in social enterprises – a moderated mediation model

Abstract

Drawing insights from the group engagement model and self-determination theory, our research explored the role of perceived empowerment human resource (HR) practices in the hybrid organizational form of social enterprise in China. Based on two studies, this paper developed and examined a moderated mediation model, linking perceived empowerment HR practices, identification motivation, work engagement, and authority work value. Specifically, in Study 1 we found perceived empowerment HR practices increased employees’ work engagement through enhancing employees’ identification motivation. In Study 2, we adopted a two-wave design to duplicate and extend this mediation model. A moderator, employees’ authority work value, was found to weaken both the mediation relationship, and the positive relationship between perceived empowerment HR practices and identification motivation. This study broadens the understanding of what social enterprises look like in alternative contexts, while providing an opportunity to explore how a HRM mechanism and its boundary condition function in large social enterprises in China.     

“一带一路”沿线国家与中国的贸易发展状况研究

研究目标：探索构建灯光数据对贸易研究的可行性。研究方法：运用1995~2012年“一带一路”沿线国家的面板数据,采用普通最小二乘法、泊松伪最大似然估计方法及工具变量法,以灯光数据作为GDP的替代量,通过传统引力模型搭建桥梁。研究发现：地理距离、边界及区域协定对中国与“一带一路”沿线国家之间贸易的显著影响表明灯光数据对贸易研究的有效性;同时,对1996~2012年贸易趋势的预测与实际贸易的对比结果显示,以灯光数据预测的“一带一路”贸易趋势与实际贸易基本吻合。研究创新：首次将夜间灯光数据应用于引力模型研究,对中国与“一带一路”沿线国家的贸易发展状况进行分析。研究价值：开拓夜间灯光数据研究贸易的先河,并结合引力模型的最新发展及微观基础思考拓展性的相关研究。     

Dress for success: the effect of exhibitors’ dress conformity and self-construal on attendees’ approach behavior

ABSTRACT

The purpose of the current study is to investigate how attendees’ approach behavior is influenced by exhibitors’ dress conformity. A 2 × 2 between-subjects quasi-experimental design was utilized for this study. Our results showed that conforming dress for exhibitors can lead to a higher level of approach behavior of trade show attendees as compared with nonconforming dress, and the effect of exhibitors’ dress styles on approach behavior is moderated by attendees’ self-construal. Findings of this study provide significant insights for trade show exhibitors and attendees.     

社会责任投资实证分析

与只考虑风险及回报的传统投资方式不同,社会责任投资在投资对象的筛选中,除考虑财务指标以外,还特别注重社会、环境、人权等企业社会责任的标准.传统的投资理念认为投资以追求财务回报最大化为唯一的目标,考虑财务回报以外的社会责任因素就会降低投资收益.在传统的投资组合的基础上构建关注利益相关者的社会责任投资模型,实证研究结果表明:社会责任投资意味着关注其他利益相关者不仅不会削弱投资回报率,而且具有高于市场的投资回报率.     

An experiment on the role of tourist attribution: Evidence from negative nature-based incidents

More so than previously, in recent years tourists have been exposed to unexpected adverse situations, such as political instability, caused by the destination. Many aspects of the destination experience do not involve service delivery and product consumption; thus, such an experience needs to be treated uniquely. Acknowledging that the effects of tourists’ inner psychological processes in this context are crucial, this study applies attribution theory to examine how tourists make sense of negative incidents caused by the destination’s natural incidents. The results show the crucial effects of globality attribution in predicting the levels of satisfaction.     

The constraints of Chinese tourists to visit Korea caused by THAAD using Q-methodology

The recent deployment of the THAAD system to South Korea has resulted in complex and controversial issues, particularly in the political, diplomatic, and economic relations between Korea and China [Perlez, J. (2017, May 31). China woos South Korea’s new leader, but the U.S. left behind a spoiler. The New York Times. Retrieved from https://www.nytimes.com/2017/05/31/world/asia/china-south-korea-xi-jinping-moon-jaein-thaad.html?_r=0]. To minimize its negative impact on international tourism, the underlying psychological mechanisms of Chinese tourists associated with this complex political issue should be determined. As an attempt to resolve the current crisis, this study identified the subjective characteristics of Chinese tourists who cancelled visits to Korea using Q-methodology and classified Chinese tourists’ attitude towards the THAAD issue. Based on respondent’s evaluations on Q-sample statements, four types of Chinese tourists were articulated, namely, patriotism, risk awareness, external dependency, and Lotte sanctions. By delving into tourists’ subjectivity, Q-methodology seems powerful to elicit intrapersonal constraints, which are deeply embedded in an individual’s psychological state. The results showed that the THAAD issue greatly influenced Chinese tourists’ personal values, beliefs, and identities.     

The role of family decision makers in festival tourism

This study assessed the role of family decision makers in participating in a festival according to five stages of festival participation. A survey process was conducted using two sampling groups: the sample for families with children and the sample for families without children. According to the results of the study, a number of marketing implications were generated. For example, the husband was revealed to more actively join transportation-related activities including driving, deciding travel routes, automobile safety checks, and filling up with gasoline. The wife was a strong decision maker in selecting restaurants or menus in the festival tourism management process. Likewise, the role of the wife is very significant, from suggesting the festival participation at the first stage to determining a revisit to the festival at the last stage. However, the children or joint decision-making patterns were not distinctive as they are said to be in other tourism literature. Findings of the study are expected to offer valuable insights for all festival stakeholders including festival vendors, local government, local residents, and festival organizers.
