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.

An Entrepreneurial Perspective of Institutional Change

Utilizing Kirzner's theory of entrepreneurial discovery, Schumpeter's two types of economic responses and the Austrian theory of institutions as building blocks, this paper constructs an entrepreneurial theory of institutional change. Focusing on the coordinating role of human institutions, this paper argues that entrepreneurial extraordinary discovery destroys the stability of institutions and creates uncertainty in the market (creative response). As a result, institutions are incapable of coordinating economic activities because market participants' stocks of knowledge are no longer adequate to solve new problems. Hence, profit gaps or mismatches of market participants' plans occur. Given new technologies, new relative prices and tastes, imitative entrepreneurs soon identify and capitalize on the opportunities created by Schumpeterian extraordinary discoveries (adaptive response). Imitators improve production methods, modify rules and alter property rights in order to improve coordination. Through learning, experimentation, trial and error, the more rewarding methods are then selected. Successful actions are imitated and repeated in the market, and gradually crystallized into new institutions which once again serve as social coordinators.

基于百度指数的碳交易市场波动率的实证研究

碳交易市场波动率研究主要基于成交量数据对收益率GARCH效应的解释作用。在互联网时代可以有更新更为有效的方法来衡量碳交易市场的波动性。基于“碳交易”词条的百度指数,以湖北碳交易市场中的收益率为样本,本文通过对比使用引入成交量和搜索量的IGARCH（1,1）模型,实证研究发现传统的量价方程的确没有解释力,而百度指数可以对收益率的GARCH效应做出部分合理的解释,这可以在某种程度上反映湖北碳交易市场的交易信息流。     

电力变压器铁芯多点接地故障的处理

电力变压器是电力系统中的主设备,它是否正常运行直接影响系统的安全运行。变压器铁芯多点接地是一种常见故障,但接地点的查找和处理在实际运行中却十分困难,因此,怎样准确、及时地诊断与处理变压器铁芯多点接地故障,对保证变压器的安全运行具有重要意义。     

现阶段中国私营企业劳资关系调整研究

改革开放以来,我国私营经济迅速发展,为国民经济的增长做出了巨大贡献。但是,伴随私营经济的增长,私营企业劳资关系的负面影响日益明显。特别是近年来,我国私营企业的劳资纠纷频频发生,甚至出现了严重摧残民工身心的山西黑砖窑虐待工人事件。在这种背景下,调整劳资关系,提高工人的地位和待遇,成为贯彻落实科学发展观、构建社会主义和谐社会的重要任务。因此,本文以我国私营企业劳资关系为研究对象,对现阶段我国私营企业劳资关系进行了系统的研究。     

浅谈我国高校校园文化商业化的发展

中国的教育历史悠久,古代类似大学的高等教育机构数不胜数。但我国真正意义上大学的建立,还是从近代开始的。随着我国教育及社会经济的发展,校园文化这一种特殊的亚文化逐渐被人们关注起来。校园文化商业化的现象,是在社会价值观、国家教育政策、社会经济等因素共同影响下产生的。本文尝试着探讨校园文化商业化的发展,就是想让人们正确认识这一现象,积极引导其进入科学化、正规化发展道路。     

青少年体质下降的社会因素分析

青少年的体魄强健,既是一个民族生命力旺盛的表征、社会文明进步的标志,更是一个国家综合实力的体现,所以青少年体质健康与否的影响远远超出了青少年个体本身。尽管青少年体质下降的影响因素是多方面,但本文旨在从社会学的角度来分析青少年体质下降的影响因素,重点分析了家庭住宅,社会意识,以及生活方式等方面与青少年体质的相关性。
