Hospitality businesses provide a natural context for mobile technology, especially given the dynamic nature of the business, the size and complexity of many hotel operations, and the need to have managers visible and overseeing multiple areas of the business (and sometimes, multiple properties) concurrently. To explore the potential for mobile technology in hospitality business contexts, we surveyed 70 full-service hotel property managers. The survey was based upon two theoretical frameworks: technology adoption model and innovation diffusion theory. Specifically, this study addressed (a) hotel property managers’ intentions to use mobile technology at work, (b) factors influencing their intentions, (c) their suggestions for implementing mobile applications in different departments, and (d) demographic characteristics of those who are inclined to adopt certain types of mobile applications. This study identified the top opportunities for mobile applications and found adoption differences based upon the respondents’ demographics as well as the factors of perceived enjoyment and relative advantages as significant determinants of hotel property managers’ intentions to use mobile technology. This study concludes with recommendations for industry practitioners and suggestions for future research opportunities related to mobile technology adoption and usage in hospitality.  相似文献

The number of service innovation articles has increased dramatically in the past 25 years. By reviewing 128 articles published between 1986 and 2010, primarily in leading marketing and innovation journals, this study analyzes the progression of service innovation research according to topicality and perspective. The authors summarize prior research by clustering it into three evolutional phases and drawing parallels with the evolution of the wider services marketing field. Overall, the view of service innovation has evolved, from a complement of traditional product innovation to a multidimensional, all-encompassing notion that entails several functions, both within and outside the firm.  相似文献

For a developing economy with a given urban wage rate, globalization in capital markets strengthens labor unions. This result hinges on the fixed urban wage rate, which leads to a constant capital–labor ratio in the urban sector. Globalization via capital inflows not only enhances the employment effect of unionization but also reduces the rent-shifting related loss in production inefficiency to domestic capital, lending a support to labor unions for developing economies. This result is contrary to the common belief that labor unions tend to be weakened during the globalization process observed after 1980s in many developed economies.  相似文献

This article tries to clarify whether negative charity appeals (i.e., advertisements emphasizing the bad consequences of not helping) or positive charity appeals (i.e., advertisements emphasizing the good consequences of helping) are more effective. Previous literature does not provide a single answer to this question and we suggest that one contributing reason for this is that different studies have operationalized appeal effectiveness in different ways (e.g., actual behavior, self-rated helping intentions, or expressed attitudes about the ad or the organization). Results from four separate studies suggest that positive appeals are more effective in inducing favorable attitudes toward the ad and toward the organization but that negative appeals are more effective (in studies 1A and 1B) or at least equally effective (in studies 1C and 1D) in eliciting actual donations. Also, although people’s attitude toward the appeal (i.e., liking) was a good predictor for the expected effectiveness in increasing donation behavior (in Study 2), it was a poor predictor of actual donation behavior in all four main studies. These results cast doubt on marketing theories suggesting that attitudes toward an advertisement and toward the brand always lead to higher purchase behavior.  相似文献

Semi-arid West Africa faces challenges to increase sorghum and pearl millet production to meet food needs for a growing human population while increasing soil carbon (C), nutrient levels, and water holding capacity that are documented benefits of conservation agriculture. This review focuses on the wealth of research on cropping systems, tillage, crop residue, nutrient, and weed management as related to conservation agriculture. It also identifies needs for multidisciplinary, integrative research to assist the transition from current production systems to conservation agriculture. Crop residue use as livestock feed, or fuel are major constraints to adoption of conservation agriculture, which could be reduced by wood production in agroforestry systems, alternate energy sources, and increased forage supply. Crop residue and grain yields are related, thus improved crop, soil, water, nutrient, and weed management to increase grain yield would also increase the supply of crop residue with potential for ‘left over’ crop residue being available for soil mulching. Incorporating indigenous shrubs and/or cover crops could also increase crop residue supply. Species diversity can be increased through crop rotation, agroforestry, cover crops, and intercrops. Higher grain and stover yields and increased profit potential for resource-poor farmers in West Africa will be required before wide-scale adoption of conservation agriculture will be possible.  相似文献

Drawing upon bottom-up theory of life satisfaction, this study develops and tests a model that links physically active leisure to people's quality of life. Results from a sample of 827 running event participants revealed that satisfaction with event participation and psychological involvement in running were significant predictors of participants’ life domain satisfaction and overall life satisfaction, both of which are common subjective indicators of quality of life. Conversely, behavioral involvement in running was a non-significant predictor of life domain satisfaction and overall life satisfaction. These findings suggest that physically active leisure may enhance participants’ quality of life by providing positive experiences through event participation and contributing to psychological involvement in physical activity.  相似文献

Based on theoretical and methodological similarities between research on recreationrelated norms and contingent valuation, three methodological issues--question format, starting point bias, and information bias--are explored as they apply to measuring crowding-related norms of visitors to two national parks. Few statistically or substantively significant differences in crowding-related norms were found to be associated with these methodological issues. Study findings suggest that measures of crowding-related norms may be relatively "robust,"and this may add weight to the "validity" of the theory and methods associated with crowding-related norms in outdoor recreation.  相似文献

ABSTRACT

In this research reflection we question the way leisure experience is commonly understood and how leisure science is commonly conducted. Specifically, we focus on advances in multiple self-theory popularized by Daniel Kahneman in Thinking, Fast and Slow, an in-depth examination of human thought processes. After establishing Kahneman's foundational perspective, we apply his thinking to leisure experience and leisure science by reviewing recent scholarship focused on the “experiencing” and “remembering” selves (2000). We conclude the reflection by discussing the implications of Kahneman's thinking for the use of self-reports by leisure scientists, as well as call for greater congruence between the selves we seek to research and our selected research methods.  相似文献

This paper is aimed to segment recreational swimmers according to their involvement level, profile the involvement groups according to demographic variables, and further test the role of negotiation strategies in the development of swimming involvement. Two hundred and sixty (N?=?260) recreational swimmers participated in the study and completed Kyle et al.'s three-facet involvement scale and Alexandris et al.’s five-dimension leisure negotiation scale. The results of cluster analysis revealed three distinct involvement groups: high, medium and low involved recreational swimmers. The high involved group consisted mainly of females, middle-aged and married individuals; the medium involved group did not have a clear demographic profile, while the low involved group consisted mainly of males and young individuals. The three involvement groups had statistical significant scores in all the five negotiation strategy dimensions, with the high involved individuals having the highest scores and the low involved individuals having the lowest ones. These results provide empirical support for the negotiation proposition, which was developed by Jackson, Crawford, and Godbey. They further contribute to the existing leisure literature by showing how demographic segmentation can be used in combination with psychographic variables in order to profile groups of participants.  相似文献

Research summary : In this article, we investigate the firm‐specific environment and its impact on firm strategy focusing on adverse changes in the policy environment and their effect on divestitures. We argue that experiencing a negative change in the firm‐specific policy environment causes firms to reassess their exposure to policy risk and their ability to manage their policy environment, making them more likely to divest. Operationalizing negative shifts in the firm‐specific policy environment through formal policy disputes between firms and governments, we find that following a dispute, firms are more likely to divest both in the country where the dispute occurs and in other countries in the same region. However, the impact of disputes on divestitures is firm specific, applying only to firms directly involved in a dispute . Managerial summary : What is the impact of change in the firm‐specific environment on firm strategy? We argue that when firms directly experience a negative change in their policy environment that is specific to them, they negatively reassess their exposure to policy risk and their ability to manage their policy environment, which makes them more likely to undertake a divestiture. We analyze formal disputes between firms and governments that arise from adverse changes in policy and find that, following a dispute, firms are more likely to divest in the country where the dispute occurs and in other countries in the same region. However, the impact of disputes on divestitures is firm specific as it applies only to firms directly involved in a dispute . Copyright © 2016 John Wiley & Sons, Ltd.  相似文献
