Perceived organizational support and coworker support as antecedents of foreign workers’ voice and psychological stress

This study investigates the effects of perceived organizational support (POS) and coworker support on the voice behavior and psychological stress of foreign workers in Macau hospitality industry. Drawing upon social exchange theory, we propose that POS and coworker support exert differential impacts on foreign workers’ promotive and prohibitive voice. We further hypothesize the negative relationships between these two types of support and psychological stress. Our hypotheses were tested by a two-wave longitudinal survey data collected from 141 foreign workers employed in four Macau hotels. The results showed that, although POS and coworker support were positively related to promotive voice, the effect of POS was comparatively stronger. Only POS had a significant and positive effect on prohibitive voice. In addition, coworker support but not POS reduced foreign workers’ psychological stress. The implications of these findings for research and practice are discussed.     

Unraveling public support for casino gaming: The case of a casino referendum in Penghu

By integrating the social exchange theory (SET) and the theory of planned behavior (TPB), this study unravels the factors associated with residents’ intention to support casino gaming development in Penghu in future referenda. Residents’ attitudes toward casino gaming development in their community were examined in the SET framework while their intention to support such development was investigated in the TPB framework. Despite that partisan difference did not have a significant interaction with TPB variables, past behavior exerted moderating effects determining residents’ intention to support casino gaming development through two TPB variables: subjective norm and perceived behavioral control. Implications are provided.

An investigation of problem-solving support and relaxation motivations on e-WOM

As a consequence of greater computer-mediated consumer-to-consumer communication within the firm's marketing communications, there has been a growing need to understand these digital interactions more explicitly. That is, we still know little about the exact extrinsic and intrinsic motivations that drive electronic word-of-mouth. The purpose of the paper is to better understand why members within community-based websites develop a need to exchange and/or develop a social bond within the community. Questionnaire data were gathered from 147 members of an online beauty forum in Australia. The findings highlight that those members seeking problem-solving support in combination with elements of relaxation will be more inclined to exchange with other community members and develop a social bond within that community. Marketing managers can capitalise these findings by strengthening problem-solving support systems and creating environments where community members can also relax and unwind to increase the exchange between members and also increase the social bonds within the community.     

Relationships of providing and receiving leisure social support to stress in older adults

Leisure has become a topic of interest in stress-coping research. This study examined the relationships between receiving leisure social support, providing leisure social support, leisure self-determination and leisure competence in older adults and their stress. A total of 639 community-dwelling older adults were recruited. Data were collected using face-to-face surveys, which included measures of leisure social support (receiving and providing), leisure self-determination, leisure competence and stress. Data were analysed using regression analysis. The results indicated that receiving leisure social support, providing leisure social support, leisure self-determination and leisure competence were significantly and negatively correlated with stress and that providing leisure social support was more significantly correlated with reduced stress than the other leisure factors. Implications of the results are discussed.     

Sustainable tourism planning and climate change adaptation in the Alps: a case study of winter tourism in mountain communities in the Dolomites

A vast body of literature suggests that the European Alpine Region is extremely sensitive to climate change. Winter tourism is closely related to climate variations, especially in mountain regions where resorts are heavily dependent on snow. This paper explores how to effectively integrate a climate change adaptation perspective with local discourses about sustainability and tourism, an increasing priority for policy-makers in the region and elsewhere. It reports on the development and application of a participatory decision support process for the analysis of adaptation strategies for local development of an Alpine tourism destination, Auronzo di Cadore (Dolomites, Italy). This experience significantly contributed to the idea that an efficient combination of modelling capabilities, decision support tools, and participatory processes can substantially improve decision-making for sustainability. The authors show that, in this case study, such a combination of methods and tools allowed for managing the involvement of local actors, stimulating local debates on climate change adaptation and possible consequences on winter tourism, encouraging creativity and smoothing potential conflicts, and easing the integration of the qualitative knowledge and the preferences of the involved actors with quantitative information. This contributed to an integrated sustainability assessment of alternative strategies for sustainable tourism planning.
