Climate change and tourism: a scientometric analysis using CiteSpace

The interaction between climate change and tourism has been one of the most critical and dynamic research areas in the field of sustainable tourism in recent years. In this paper, a scientometric analysis of 976 academic publications between 1990 and 2015 related to climate change and tourism is presented to characterize the intellectual landscape by identifying and visualizing the evolution of the collaboration network, the co-citation network, and emerging trends. The results show that the number of publications in this field has increased rapidly and it has become an increasingly interdisciplinary research subject. The most productive authors and institutions in this subject area are in Australia, USA, Canada, New Zealand, and European countries. In this paper, we identify the most pressing topics of climate change and tourism research, as represented in the existing literature, which include the consequences of climate change for tourism, necessary adaptations, the vulnerability of the tourism industry, tourist behaviour and demand in response to climate change, and emission reductions in the tourism sector. The paper presents an in-depth analysis of climate change and tourism research to better understand global trends and directions in this field that have emerged over the past 25 years.     

Key impact factors of visitors’ environmentally responsible behaviour: personality traits or interpretive services? A case study of Beijing’s Yuyuantan Urban Park,China

The environmentally responsible behaviour (ERB) facilitates the sustainability of tourism destinations. This study aims to identify the key impact factors to promote visitors’ ERB in urban park and examine the impact mechanism. A total of 567 visitors were surveyed in Beijing’s Yuyuantan Urban Park. Structural equation modelling results indicate that personality traits are the most important factors that affect visitors’ ERB, while the effect of how satisfaction with interpretive services plays upon visitors’ ERB using place attachment as a mediator. Openness traits positively affect satisfaction with experiential services and general behaviour. Additionally, implications in urban park management are provided.     

Segmenting and Understanding Publics in a Social Media Information Sharing Network: An Interactional and Dynamic Approach

This study segments social media publics and analyzes their informational behaviors during organizational crises. With a public-centric perspective, our study highlights how social media publics interact with each other (i.e., interdependence) and share different information through crisis stages (i.e., dynamics). Following the situational approach to segmentation, we identify different types of social media publics (i.e., influentials, broadcasters, and followers) based on their informational behaviors and their positions in an information sharing network. Crisis managers are recommended to pay more attention to publics with higher influence, namely key influentials and broadcasters. In addition, we try to understand social media publics’ changing concerns by analyzing whether and how publics share messages of different themes and forms in different stages of a crisis. Crisis managers are recommended to customize crisis communication content to fit publics’ needs, prioritize organizational resources, and maximize positive communication effect. With big data from Chipotle’s E. coli crisis, we analyzed the Twitter activities surrounding this crisis over a 6-month period. Our segmentation receives initial support from the network analysis and content analysis on the Twitter data, which lays the foundation for effective social media crisis management.     

压力测试与商业银行的资本管理

美国银行监管机构耗时四个月之久,动用了150名专家和分析师对美国19家最大银行控股公司的资本水平进行了罕见规模的压力测试,从而确定了这些金融机构的资本缺口.美国银行监管机构十分看重压力测试,从宏观经济情景选择、微观经济变量到会计细节处理都进行了统一部署和安排,因此测试结果符合客观实际和市场的主观期望.我国刚推行压力测试法,尚需要进行深入的探索,美国这次测试为我们提供了值得借鉴的经验.     

公司治理结构、市场环境与自由现金流

目前,自由现金流已成为考察上市公司治理质量的重要指标,为此,本文选取A股和香港上市公司的数据对治理结构与自由现金流的关系作了比较研究。实证结果表明,控制股东持股与自由现金流存在正相关关系,A股公司控制股东比H股和香港非中资公司控制股东更倾向于将自由现金流留在公司内部;除香港非中资公司外,其他类型的公司中机构投资者没有发挥对自由现金流代理问题的抑制作用;独立董事在减少自由现金流方面发挥了积极作用,香港非中资公司独立董事在抑制自由现金流的代理问题中发挥的作用大于H股和A股独立董事。     

基于需求分析的遗产景区旅游解说系统优化研究——以峨眉山景区为例

解说需求研究是景区旅游解说系统优化的基础.本文采用问卷调查法和统计分析方法,从解说媒体和解说内容两个方面,对峨眉山景区游客的解说需求进行了分析.结果显示,游客对景区解说媒体有偏好,需求度最高的媒体是讲解员,其次是标识牌和解说牌;最感兴趣的解说内容是表现峨眉山突出特征的自然生态和佛教文化,其次是旅游活动项目,且游客特征与部分解说内容相关性显著.分析发现,景区游客对旅游解说内容有扩展需求,解说还具有扩散旅游客流的功能.根据游客的解说需求特点和对景区解说现状的实地调查,提出了完善解说媒体布局、加强景区重要特征解说、扩展解说内容和增强解说的针对性,以及提高解说员素质等景区解说系统的优化措施.     

汶川地震后入川游客的动机及对四川旅游受灾情况的感知研究

在灾后旅游业的研究中,游客对受灾目的地的感知情况的实证案例研究相对较少。本文对汶川地震后到四川旅游的国内游客按动机进行聚类,将游客划分为观光游览、公务或商务、地震旅游和多重动机4种类型。进一步的调查分析显示,游客对四川旅游业的整体恢复状况和恢复措施具有较高的认同,对地震所产生的影响也有一定程度感知。不同类型的游客在四川旅游形象感知、旅游业地震影响感知和对四川旅游恢复措施的看法方面存在一定差异,本文对这些差异进行了探讨,并在此基础上进行了总结分析。

Examining the relationship of work–family conflict to job and life satisfaction: A case of hotel sales managers

The study was designed to clarify the ambivalent relationships between work–family conflict (WFC) and measures of satisfaction. Both the direct and indirect effects of WFC on job and life satisfaction were investigated. Job satisfaction was also separated into two components: affective reaction and cognitive appraisal. Data were collected by a field survey of 121 sales managers from 26 hotels in China. Structural Equation Modeling (SEM) indicated a critical role of one's affective reaction to his/her job in the relationship between WFC and life satisfaction. Specifically, the present study found that both work interfering with family (WIF) and family interfering with work (FIW) have significant negative association with an individual's affective reaction to his/her job, while only FIW reduced the cognitive appraisal of a job. Further, affective reaction, rather than cognitive appraisal, had a significant positive correlation with life satisfaction. Finally, FIW was negatively associated with life satisfaction. The results suggest the strategic role of family friendly human resource polices in hotels.
