发展逆向物流的利益相关主体及其博弈

发展逆向物流与社会、企业及公众息息相关,政府、企业和消费者是其利益相关主体。各主体对发展逆向物流的诉求不同,即动力机制不同,主体之间博弈的结果影响逆向物流的发展。通过构建博弈模型,分析主体间博弈过程,探讨其参与逆向物流的动机,为发展逆向物流提供决策依据。     

A comparison of the National Geographic Stewardship Scorecard Ratings by experts and stakeholders for selected World Heritage destinations

The National Geographic Society Center for Sustainable Destinations Stewardship Scorecards for 2003 and 2006 compared ratings by “experts” for 33 World Heritage Site destinations. Nine (27.3%) improved by four or more points and six (18.2%) decreased by four or more points in the three years. In 2006, local stakeholders rated these World Heritage destinations using the same criteria as the experts. Stakeholders rated six destinations (18.2%) lower and almost half of the 33 destinations (48.8%) increased by five or more points. A moderate positive correlation was determined between the ratings of the experts and stakeholders. Comments by experts and stakeholders related to each of the scorecard criterion measures were analyzed. ANOVA and t-test were performed to examine the six stakeholder categories ratings for each of the six criteria and the results are presented. The assumptions and limitations of the survey methodology are discussed along with recommendations for improving the Destination Stewardship Scorecard Survey.     

Physically Active Leisure and Tourism Connection: Leisure Involvement and Choice of Tourism Activities Among Paddlers

Leisure and tourism activities may be integrally related for some. This study examined the relationship between the preferred leisure and tourism activities and psychological involvement in paddling of a group of paddlers. Participants were surveyed at the completion of a paddle tour. Data were analyzed using frequencies, confirmatory factor analysis, cross-tabulations, and ANOVA. Four types of leisure-tourism connection (LTC) were identified. People more highly involved with paddling tended to paddle while on vacation compared with other LTC types. The findings provide empirical evidence for previous assertions proposing a connection between involvement in leisure activities and subsequent tourism behaviors.     

Usage Behavior Causal Model Construction for B&B-Owned Websites—from the B&B Owner/Operator Perspective

Previous studies on B&B (Bed and Breakfast) website usage behavior focused mainly on clients. It has been seldom researched to apply the Technology Acceptance Model (TAM) to verify the owner/operator usage behavior on B&B websites. This study aims to validate the causal relationship among beliefs, usage attitude, and behavior intention in website usage of B&B owners/operators. The results revealed that the TAM was recognized and the perceived ease of usage of B&B websites plays the most important role on the behavioral intention of B&B owners/operators. An easy and effective B&B website may allow an owner/operator to improve a B&B’s operational performance. Age has a significantly negative influence on perceived ease of use for B&B websites and educational attainment has a positive impact on perceived ease of use for B&B websites. Finally, conclusions and implications were discussed. This study can be used as a theoretical foundation and reference for further exploring related issues.     

利用农作物秸秆生产草酸

我国是农业大国,农作物秸秆资源丰富,随着人们生活水平的提高,清洁能源的推广及家畜养殖量的减少,秸秆在农村多被弃置,很多时候被付之一炬,不仅浪费资源还严重污染大气环境。研究利用秸秆生产草酸,旨在为秸秆综合利用寻找出路,走循环经济道路。     

Validating a multidimensional perspective of brand equity on motivation,expectation, and behavioural intention: a practical examination of culinary tourism

This study presents a brand equity theory of culinary tourism by integrating behavioural theory with the mediation-moderation model. The culinary tourism brand-equity model underscores the value of tourists’ expectations as a means to enhance the effects of travel motivation on behavioural intention. This study empirically tests this theory using a sample of 513 foreign tourists and provides evidence that travel motivation mediates the relationship between the four critical attributes of brand equity and behavioural intention. Furthermore, the results confirm the interrelationships within brand equity and reveal that tourist expectations positively moderate the relationship between travel motivation and behavioural intention. Implications for theory, research, and practice are discussed.     

建国初期农家支出研究

建国初期,由于土地改革这一生产关系的变革,农民收入水平呈增长趋势,使得农家支出水平亦不断增长。在农家支出结构中,合作化完成前支出主要用于生产、生活两个方面,合作化完成后主要用于生活方面。总体来看,吃、穿等生活性支出在农家支出中始终占据绝大比重,由此决定了当时农家消费是一种温饱型消费。同时,自给性消费始终占据主导地位,说明农家消费具有典型的自给自足性质。     

商务英语专业学生思辨能力培养研究：困境、理念与路径创新

近年来,思辨能力的培养日益受到高等教育界的关注,然思辨能力的研究却陷入多重困境。以促进人的整体发展为主要目的的＂全人教育＂应是商务英语专业学生思辨能力培养的理念基础,《高等学校商务英语专业本科教学要求》（试行）的跨学科整合性应是学生思辨能力培养的新路径。     

The loyalty process of residents and tourists in the festival context

Few attempts have been made to find out if the loyalty process for residents and tourists in the context of cultural festivals is the same. This study investigated the influence of involvement on satisfaction as factors contributing to the likelihood of returning to an annual festival for residents and tourists. A sample of 412 attendees of a cultural and historic festival in the Midwest region of the USA was surveyed. The results showed that both residents and tourists who were more involved with the festival had higher satisfaction levels. However, only residents who were highly satisfied with the festival were more likely to attend again, whereas tourists' satisfaction level did not significantly influence their likelihood of returning. For tourists, it is likely that their quest for novelty is influential in shaping their future intentions. Implications of this result for the sustainability of cultural festivals are discussed.
