Service Climate in Restaurants

This study focused on identifying the most relevant dimensions of service climate in restaurant settings. A series of confirmatory factor analysis were performed to check the construct validity of the service climate using data collected in a field survey of 452 frontline employees working in 31 different foodservice establishments. Four dimensions of service climate were identified: service vision, service training, supervisor support, and reward and recognition. The validated 22-item scale of service climate can be used as a potential tool for evaluating the service climate in foodservice establishments.     

The influence of chronic and temporary accessibility on trust and policy support

Abstract

Food is very closely related to our everyday life and consumers are intolerable to food risk. The impact of media report on food risk perception has been addressed but more elaborated approach on consumers’ cognitive process of food risk perception via media is needed. Theoretically guided by accessibility theory, we examined the relationship between consumers’ perception of food risk (i.e. food schema), media use, media frame, trust, and policy support. Furthermore, anger was employed as a mediating variable influencing on trust and policy support. Results found that the level of media use had a significant positive effect on trust and policy support. Among the media frames, the government responsibility frame and corporate responsibility frame were shown to be negative predictors for trust and policy support. As for the food schema, checking schema was the most influential negative factor on trust and policy support. Anger was found to exert a negative effect on trust and policy support but this effect decreased if the level of trust was high. In terms of the relationship between media frames and the food schema on anger, most food schema reduced the strong positive effects of the media frame on anger. This means peoples’ anger induced by media frames can be diminished by individuals’ specific food schema. Both theoretical and practical implications are discussed.

Managing and modeling the price reduction effect in mobile telecommunications traffic

As needs for telecommunications services diversify, an increasingly wide range of services is becoming available in the market. Service price reduction is one strategy used by service providers to retain existing subscribers. A price reduction for one service, however, can affect the individual-level usage for other services. Price reductions can also be imposed on a service provider by regulation. For these reasons, understanding how price reductions affect service usage is of growing importance to the telecommunications industry for purposes of pricing and tariff development. In this paper, an individual-level usage model for telecommunications services is developed and the effects on usage of a price reduction are analyzed. The model is applied to age-stratified aggregate traffic data for a Korean mobile telecommunication service provider. Finally, a 0-1 integer programming model is proposed for choosing which market segment should be targeted with a price reduction to minimize revenue loss. These models can be applied to market segmentation and price reduction strategy.     

Optimal pricing strategy for foreign market entry: a game theoretic approach

Given that pricing plays an important role in a company's international competitive strategy, researchers have long argued the need for theory building in the area of international pricing. This study develops an optimal pricing strategy for foreign market entry using a game theoretic framework. The proposed model assumes two firms, a local incumbent and a foreign entrant, competing in a market. Consumers know the quality of the incumbent's offering, but do not know how it compares to that of the foreign entrant's. Based on these assumptions, and using the theory of inference making, we propose an upward price distortion by the entrant firm as an optimal entry strategy under incomplete information. The paper presents a game theoretic derivation to establish that the game has a unique intuitive separating equilibrium where the entrant firm stands to gain by engaging in upward price distortion to signal high quality to consumers.

Predictors of Career Success Among Lodging Revenue Managers: Investigating Roles of Proactive Work Behaviors

This study integrated the growing literature of proactive work behavior with career success among lodging revenue managers. Proactive work behavior is a timely, relevant, and important research topic for today’s workplaces in the hospitality industry. The aim of this research was to test a model for linkage among four dimensions of proactive work behavior and career success, among 280 lodging revenue managers, while controlling for work experience, age, and gender. First, the confirmatory factor analyses examined the measurement models of proactive work behavior and career success. Next, hierarchical regression analyses demonstrated that all four dimensions of proactive work behaviors contributed positively to subjective career success, but not objective (extrinsic) career success.     

On bending (down and up) property of reliability measures in mixtures

In this paper, we study the bending property of the failure rate, reversed hazard rate, mean residual life and mean inactivity time in mixtures. For those four reliability measures, the weak and strong bending properties are studied and discussed, respectively. The results are illustrated with suitable examples, where most of them are relative to the model of proportional reliability measures.     

云南核桃产业发展中存在的问题与对策

云南现有核桃面积30.7万hm2,居全国之首,核桃年产量达6.8万t,占全国产量的20%。大理州宾川县拉乌乡核桃收入在万元以上的农户达500多户,核桃产业已成为富民强县的支柱产业。但是,云南核桃每公顷产量很低,仅225kg产品以销售核桃仁、核桃为主,产品加工与营销严重滞后,制约着核桃产业的发展。产业的发展尚需科学规划、合理布局;加速发展加工业延长产业链;开发新产品,建立产品集散市场与行业协会等有效措施,促进核桃产业的健康发展。
