Meanings of leisure for older people: an Australian study of line dancing

In Australia and in many parts of the world, older people participate in line dancing. Our phenomenological study explored whether attending a regular line dancing class might offer a group of older people opportunities for active and successful ageing. Our research investigated the meanings and practices fostered in a community line dancing class in Melbourne. We gathered data via an interview with the teacher of the group, observation of a class and two focus group interviews with 25 members. Data were analysed using Interpretative Phenomenological Analysis that is reported thematically under headings of: Belief in the efficacy of line dancing, Physical and emotional benefits, YouTube clips as instructional reinforcement and promotion, and Socialising. The findings show that participation in the class offered older student’s opportunities for dance and music engagement, active and successful ageing, health and well-being, social connection and purposeful leisure. The teacher of the class modelled serious and successful leisure and advocates for dance as holistic training for older people. We position our participants on a continuum of leisure engagement that ranges from the casual to the serious. Further research is required to support arguments for the efficacy of dance as a leisure pursuit for older adults.     

中国城镇化包容性发展中的公共投资支持影响研究

本文通过构建城镇化包容性发展指标体系，测度出中国2003—2015年30个省级区域的城镇化包容性发展指数，经莫兰指数检验发现其具有显著的空间正相关性。进而采用空间计量模型，基于户籍制度改革背景，从生产性公共投资、社会性公共投资与环保性公共投资三个方面研究公共投资对城镇化包容性发展的影响。研究结果表明，生产性公共投资与社会性公共投资对城镇化包容性发展均存在显著的正向支持作用，且户籍制度改革变量与二者产生了正向的交互作用，说明随着对人口流动限制的放松，生产性公共投资与社会性公共投资对城镇化包容性发展的支持作用有所增强，但环保性公共投资未能表现出显著的支持作用。在未来城镇化进程中，应当优化调整中国公共投资的行业结构与区域结构，从而更好地提升城镇化包容性发展水平。     

Green multi-tier supply chain management: An enabler investigation

Stakeholder pressure, from actors including regulators, consumers and non-governmental organizations, has made organizations more responsible for poor environmental performance of their direct and sub-suppliers. Thus, green multi-tier supplier management (GMSM) has become an emergent topic. Yet it is still unclear how to enable GMSM practices effectively, i.e. how to enable sub-suppliers' environmental performance improvement. To help address the gap in the literature, this paper aims to identify enablers for sub-suppliers' environmental performance improvement, and it further applies a Decision-Making Trial and Evaluation Laboratory (DEMATEL)-based case study method to evaluate inter-relationships among these enablers and improve the focal company's GMSM practices, by using action research (AR) method principles. The data analysis and discussion with a follow-up evaluation after two years provided insights for the successful implementation of GMSM. The results show that top managers’ support from the organizations is a prominent and necessary foundational enabler. An interesting observation is that close proximity of supply chain members is regarded as a very prominent enabler. Evaluation and feedback on these enablers two years later found that the enabler mapping was beneficial, allowing them to address the most influential enablers, and thus the GMSM practices of the focal company has been highly improved. This paper concludes with directions for further research.     

巴中市农田土壤重金属分布及生态风险评价

[目的]通过测定秦巴山区巴中市农田土壤中镉(Cd)、铅(Pb)、锌(Zn)3种重金属元素的含量及分布特征,为农田重金属防治科学决策的制定提供数据支撑。[方法]文章采用内梅罗指数和潜在生态风险指数来综合评价巴中市土壤重金属污染状况。[结果]巴中市农田土壤锌平均含量比四川省丘陵地区背景值高6.78%,而镉和铅含量均未超出其背景值,总体评价良好,但各检测点之间差异较大,镉含量最多超出背景值5.7倍。内梅罗指数评价结果显示,全市平均综合污染指数为1.10,接近清洁状态。潜在生态风险指数评价结果显示,其最小值为15.94,最大值为177.74,平均值为35.38。[结论]巴中市农田土壤重金属污染状况基本处于低度风险级别,但各地块污染程度不尽一致,应因地制宜,采取适当措施治理土壤污染。     

基于多源数据的自然生态空间分类体系构建及其识别

研究目的:探讨市县尺度下自然生态空间分类体系和多源数据下自然生态空间识别方法。研究方法:采用归纳比较法构建自然生态空间分类体系,通过综合分析法建立多分类体系转换机制,运用GIS空间分析法识别自然生态空间。研究结果:(1)市县级自然生态空间是指生产性空间和承载性空间以外,以发挥土地生态系统服务功能为主导,以提供生态产品为主,对维护区域生态系统稳定性,保障区域生态安全格局具有重要作用的用地空间;(2)自然生态空间可分为基础生态空间和人工生态空间两个一级类,10个二级类,26个三级类;(3)2015年鹤壁市自然生态空间总量606.08 km~2,其中基础生态空间554.41 km~2,人工生态空间51.67 km~2。研究结论:依据市县尺度自然生态空间分类体系,运用多源数据融合转换识别方法能快速准确识别自然生态空间数量和空间分布。

Road safety determinants in low and middle income countries

The objective of this article is to summarize and review the literature on the determinants of road traffic injuries and fatalities, to identify the relevant research gaps in particular for low and middle income countries. We also present a cross-country analysis of the determinants of road traffic injuries and fatalities that take into account a wide range of potential environmental, economic and social factors. The present study focused on differences based on the level of development. The goal was to identify relevant commonalities that may assist in the creation of road safety policies common to countries at a similar level of development. The countries were divided according to the level of gross national income per capita, and these income-level groups were the primary units of interest. The results presented here focus on the differences by income level.     

The complexity of consumer experience formulation in the sharing economy

The study examines the complexity of the factors that influence overall perception among tourists who use peer-to-peer accommodation during their vacations. More specifically, it employs fuzzy-set Qualitative Comparative Analysis to analyse data from a sample of 712 peer-to-peer holidaymakers visiting Athens, Greece, and examines the socio-demographics of age and income along with the simple attributes of perceived risks, marketing and advertising, social aspects, and price and quality issues. The findings reveal three sufficient configurations that are able to influence the overall experience: (i) the price-quality nexus, (ii) risk perspective, and (iii) social interaction. The research also compares nonlinear analysis with the dominant parametric methods in tourism and hospitality research (regression; Cramer’s V), highlighting the suitability of the former for complexity examination. It further progresses from fit to predictive validity for the examined models, and contributes to both theoretical and methodological domains.     

Promoting quality-of-life and well-being research in hospitality and tourism

There is an increasing interest in quality-of-life/well-being research in hospitality and tourism. The goal of this paper is to further promote the development and use of quality-of-life/well-being concepts in the discipline by reviewing seven major theories of quality of life and well-being (and their application in hospitality and tourism based on the research that I and my colleagues have conducted over the years) and suggesting future avenues of research. The theories discussed are self-congruity theory, self-expressiveness theory, bottom-up spillover theory, leisure benefits theory, goal theory, need hierarchy theory, and broaden-and-build theory.
