A performance evaluation model for international tourist hotels in Taiwan—An application of the relational network DEA

This research utilizes relational network data envelopment analysis to construct a model to analyze the efficiency and effectiveness of international tourist hotels (ITHs) in Taiwan. The different production processes within the hotel are evaluated, as well as the relationships between efficiency, effectiveness, and overall performance. Finally, based on the results, we recommend ways of enhancing the overall performance of the hotel industry in Taiwan.     

When does an employee not help coworkers? The effect of leader–member exchange on employee envy and organizational citizenship behavior

Using a sample of 233 front-line hotel employees, we examined leader–member exchange (LMX), envy, and organizational citizenship behavior (OCB). The results from path analysis support the research model that employees who have a relatively poor working relationship with their supervisor (i.e., low-quality LMX relationship) were more likely to show higher levels of envy than employees who have relatively closer working relationships with the same supervisor (i.e., high-quality LMX relationship). Ultimately, higher levels of envy decreased employee voluntary helping behavior (i.e., organizational citizenship behavior, OCB) toward coworkers. This finding suggests that employees perceiving a poor working relationship with their supervisor committed less voluntary helping behavior toward coworkers than their counterparts. Implications for managers and suggestions for future research are discussed.     

Sustainable tourism development and residents’ perceptions in World Heritage Site destinations

Set in Malaysia’s Lenggong Valley World Heritage Site (WHS), this paper uses stakeholder theory to explore the heterogeneity of positive and negative perceptions among residents and their effects on residents’ support for and participation in sustainable tourism development. Data from 221 completed questionnaire surveys revealed heterogeneous negative perceptions across residents’ age, level of education and economic involvement in tourism. Moreover, residents’ positive perceptions had a positive effect on their support for and participation in tourism development. This study contributes to the resident perception literature by using stakeholder theory to conceptualise the heterogeneity of residents’ perceptions and by examining the effects of those perceptions on their support for and participation in tourism development in a rural WHS destination in the developing world. Furthermore, the findings of this study have practical implications for local authorities aiming to improve residents’ support and participation in tourism planning for sustaining tourism development.     

Empowerment and resident support for tourism in rural Central and Eastern Europe (CEE): the case of Pomerania,Poland

Despite empowerment being a crucial component of sustainable tourism, few scholars have quantitatively operationalized empowerment and looked at how it applies to rural societies within the post-communist European Union (EU) member states. Knowing the high priority of sustainable rural development goals within the EU, empowering residents within these post-communist societies has become a pertinent issue especially where those societies appear more reluctant to engaging in democratic ways of decision-making. In response to this gap, this study tests the cross-cultural validity of the Resident Empowerment through Tourism Scale, and then evaluates how empowerment predicts residents’ support for tourism within the municipality of Choczewo, Pomerania, Poland. Using a theoretical perspective that blends Social Exchange Theory with Weber's Theory of Formal and Substantive Rationality, these non-economic empowerment dimensions are coupled with a measure of resident perceptions of economically benefiting from tourism to see if rural residents in Choczewo, Poland, are more swayed by the economic or non-economic benefits of tourism. Results show that residents within this Central and Eastern Europe setting are more influenced by the pride and self-esteem boost associated with psychological empowerment and the perceptions of increased community cohesion (i.e. social empowerment) than the economic promises of tourism.     

Community participation in World Heritage Site conservation and tourism development

This study investigates the factors contributing to community participation in a World Heritage Site (WHS) using Motivation, Opportunity, and Ability (MOA) model. We examined the effects of these factors on three levels of community participation. The findings showed that motivation had the greatest positive effect on the low level of community participation. Opportunity had the greatest effect on the high level of community participation. Among the dimensions of ability, namely awareness and knowledge, the findings showed that more aware residents were more interested in low level of community participation, whereas residents with more knowledge were more interested in high level of community participation. This study contributes to the tourism development and WHS conservation and management literature by examining the effects of MOA factors on three levels of community participation. Moreover, this study has a number of practical implications for local authorities in terms of community participation.

我国高速铁路对城市贸易发展的影响分析 ——基于对外开放程度不同城市的实证

高速铁路凭借其特有的技术经济特性成为影响城市贸易发展的重要驱动力,但其对城市进出口贸易有何影响及如何影响需进一步探索。通过对三个开放等级度56个城市的2006-2018年面板数据,运用双重差分模型(DID)进行实证研究,分析出高铁对城市贸易发展的影响情况。结论表明：高铁对开放程度较低城市的贸易发展有显著的促进作用;高铁对总体城市的贸易发展的影响并不显著;高铁主要是通过促进城市进口贸易的发展来提升城市贸易的整体水平。     

薜荔在室内光照适应范围的研究

研究了薜荔的绿叶(Ficus pumila)及花叶(Ficus pumila'Sunny White')品种的室内光照适应范围问题;根据室内光的分布,选择房间内具有代表性的光区进行栽培试验;在16～28℃,RH30%～64%条件下;经栽培82天后,用LI-6400测定其不同光强下的光合特性,计算光补偿点、光饱和点、最大净光合速率,并测定不同试验区枝条长度的生长量;结果表明,在该条件下,绿叶品种生长的适宜光照为7.8～527.0μmol/m2.s(392～26350 lx),薜荔花叶品种为6.9～491.0μmol/m2.s(347～24550 lx)。     

Valuation of ecosystem services provided by irrigated rice agriculture in Thailand: a choice experiment considering attribute nonattendance

This research investigates how the public of a middle‐income country, Thailand, values ecosystem services associated with irrigated rice agriculture using a choice experiment. The results show a significant willingness to pay for services such as drought mitigation, water quality and the environment and maintenance of rural lifestyles and rice landscapes. The iterative procedure developed to fully analyze the incidence of attribute nonattendance (ANA) improved the model fit when compared with a multinomial logit model or an ANA model with potentially only one attribute ignored at a time (ANA‐1). Moreover, the inferred probability of the class of respondents having attended all attributes was 45%, compared to 9% with ANA‐1 model. However, it also suggests that 55% of the respondents made their choices by considering only two of the five attributes. Finally, this research also suggests that failing to consider ANA does not change the public ranking of scenarios contrasted by the services they would provide but would overestimate the WTP for these scenarios.
