The perceived destination image of Hong Kong on Ctrip.com

This study examines the perceived destination image of Hong Kong among visitors from mainland China, as revealed on the travel blog of Ctrip.com. Textual analysis and the overall evaluation scores of 2247 blog entries indicate that this image is positive in all aspects among these visitors. They are particularly impressed by the shopping experience, as both product quality and prices are considered competitive in Hong Kong. These visitors also evaluate overall food quality highly, although the high price of food and accommodation leads to the perception that Hong Kong is an expensive tourist destination. Managerial implications are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

The relationship between managers' environmental perceptions,environmental management and firm performance in Spanish hotels: a whole framework

The examination of the possible direct link between environmental protection and firm performance has generally produced mixed results. This paper contributes to the literature by considering the antecedents of hotel managers' environmental attitudes to check whether perceptions of the external and internal factors are behind the adoption of a proactive environmental management. The study also tests whether or not the resource‐based view of the hotel mediates the positive relationships of proactive environmental management and improved environmental performance with competitive advantage and financial performance. This contribution is original because this study develops a comprehensive whole picture of this path process, which has previously only been partially discussed in the literature.

Valuing Tourist Destinations: an Oaxaca‐Blinder Approach

Destination branding influences destination selection process and future tourist behaviors. However, measuring brand equity is difficult in the case of tourist destinations. The aim of this paper is to determine which part of the price of a tourist service can be explained by differences in characteristics and which part can be explained by differences in destination branding. Data from Catalonia, Valencia, the Balearic Islands and Languedoc‐Roussillon are used as well as the Oaxaca‐Blinder decomposition method. More than a half of the gap (between prices paid by French and Spanish tourists for an equivalent hotel) can be attributed to destination branding. Copyright © 2012 John Wiley & Sons, Ltd.     

What role does culture play? A look at motivation and job satisfaction among hotel workers in Brazil

Job satisfaction has been associated with positive organizational outcomes such as increased employee productivity, higher innovation and reduced turnover, all of which are linked to improved firm performance. Motivation is considered to be a primary determinant of job satisfaction. Yet little research has focused on the links between motivation, job satisfaction and the impact of culture in the workplace. This qualitative research uses Herzberg's Two-Factor Theory of Motivation to assess job satisfaction in the Brazilian hotel industry. The results partially support the theory and suggest that culture influences the degree of job satisfaction.     

Training policy and organisational performance in the Spanish hotel industry

There is currently a general agreement about the importance of training as a tool to help companies in the development of sustainable competitive advantages based on their human resources. Staff qualification is not an option in the tourism industry; human capital training actually becomes a determining factor to be able to achieve a differential positioning within the sector. In Spain, where the tourism sector is a strategic element, it becomes essential to analyse the training policy applied by tourism enterprises with the aim of assessing its quality and effectiveness. The objective sought in this study is to identify the main factors related to training policy that have an impact on performance. The study carries out an empirical research into the effects that training practices cause on performance levels in the Spanish hotel industry using a sample of 110 hotels.     

酒店企业安全影响因素分析及对策

安全是酒店得以生存和发展的首要因素之一。对于酒店来说,没有安全就没有一切。从酒店运营的环境来看,存在着诸多影响安全运营的危险源。当前,虽说绝大部分酒店管理者都认识到安全工作的重要性,但在日常工作中却缺乏系统的安全知识和应对手段,造成酒店安全事故时有发生。因此,酒店业的管理者要树立科学的安全观念,应用系统工程理论查找酒店存在安全隐患的部位、分析隐患形成的原因,通过建立酒店职业安全管理体系,对酒店存在的安全隐患进行预防和控制,实现酒店安全运营。

旅游饭店餐饮场所的安全管理研究

安全是人较低层次的需求,因此是其他高层次需求得以满足的基础。旅游饭店餐饮场所的高档次消费性、高开放性、高人员流动性以及高服务集中性使其成为旅游饭店中安全管理的薄弱环节,加强餐饮场所的安全管理有助于提高顾客满意度,因此旅游饭店对其必须加以重视。
