Deteriorating inventory model for ready-to-eat food under fuzzy environment

Decreased costs and enhanced customer satisfaction are two main objectives of SCM, and good inventory policy can achieve both simultaneously. Product perishability is a critical aspect of inventory policy. Ready-to-eat food products are very common consumer goods that are, in fact, perishable. The value the RTE food retains is, however, closely dependent on its quality. From the vendor’s point of view, quantifying quality and remaining value should be a critical business issue. In consequence, we combined the traditional deterioration model and quality prediction model to develop a new deteriorating inventory model for RTE food products. This new model quantifies food quality and remaining value. We also improved the new model by fuzzifying storage temperature to simulate temperature fluctuation. The proposed model uses real deterioration rate data. Numerical analysis is conducted in a case study. Overall, the model demonstrates that high storage temperatures reduce profits and force shorter order cycles.     

The Impact of Tour Guides’ Physical Attractiveness,Sense of Humor,and Seniority on Guide Attention and Efficiency

In this study, we investigated whether tourists view attractive tour guides as more competent, humorous tour guides as more approachable, and experienced tour guides as more professional, and whether these three factors influence the effectiveness of tour guide interpretation. The results indicated that physical attractiveness and humor had additive effects on interpretation effectiveness when combined. Although some tour guides were not physically attractive, experience provided an additive effect on interpretation effectiveness. Thus, we recommend discarding stereotypes regarding physical attractiveness and improving education and training in humor for tour guides. Experienced tour guides wearing appropriate attire also increases interpretation effectiveness.     

Reexamining the direct and interactive effects of governance mechanisms upon buyer–supplier cooperative performance

This study aims to explore the effect of governance mechanisms (including both formal and social controls) upon the buyer–supplier cooperative performance in supply chains. Empirical evidence obtained via a mail survey from 106 firms participating in the Taiwanese “Center Satellite Production System” indicates that (1) there is an inverted U-shaped relationship between formal control and cooperative performance; (2) social control has a consistent positive effect on cooperative performance; and (3) the joint use of formal control and social control could enhance cooperative performance in supply chains but only in cases with moderate usage of formal control. Otherwise, social control becomes a supportive factor that repairs cooperative performance damage from overwhelmingly applied formal control.     

Reliance on Income Support in Australia: Prevalence and Persistence

Welfare dependence or reliance is widely regarded to have adverse consequences for both the community and welfare recipients, yet there have been few studies of the extent and nature of welfare reliance. Indeed, the concept of welfare reliance does not seem to be well defined. In the present paper, we clarify the meaning of the concept and derive reliance measures consistent with this concept. These measures are applied to describe the extent and nature of reliance on income support payments in Australia of persons aged 15–64 years, using Australian Bureau of Statistics income survey data and Australian government administrative data for income support payments.     

An empirical study on the effects of an enterprise fan page

Most major enterprises have invested in social networking to provide services, promote products, or communicate with customers. However, to date, no clear understanding on the effects of social networks on business performance has emerged. This study examines the relationship between the capability of the enterprise to manage social networks and the resultant benefits of their investing in the social network. A fan page on Facebook is the selected target of study. By analyzing the effort required to manage a fan page, we measured the fan-page managing capability by its number of fans. Then, we proposed six hypotheses for empirical examination of the causal relationship between enterprises’ social network managing capability and business benefits. The study applied two-stage data collection and testing. The first stage is to build a general understanding of the relationship between the number of fans and business revenue. Based on findings of the first stage, the study tested the hypotheses on selected global firms and sought patterns of benefits generated from the fan page. This study builds deep understanding from various aspects about fan-page effects on enterprises, and proposes that firms that provide products and services with characteristics of low-product price, short-product durability, and low-customer involvement are empirically influenced by the management of their fan pages.
