Demographics,Personality Traits,Roles, Motivations,and Attrition Rates of Hospice Volunteers

ABSTRACT

The authors conducted a review of prior research on hospice volunteering. The results show that, in most cases, the hospice volunteer is a white, married, middle-aged, financially comfortable, unemployed, female who has some college education, strong religious beliefs and has experienced the loss of someone close (see Tables 1 and 2). The results also show that hospice volunteers tend to share certain personality traits reflecting compassion, tolerance, empathy and sensitivity among others. Volunteers tend to fulfill four roles: direct patient support, education, clerical assistance, and professional services (Bunn 1985). Motivations for volunteering and for continuing one's work as a volunteer appear to be for both personal and altruistic reasons. Primary reasons for discontinuing volunteer service include burnout, communication problems, unrealistic expectations, and insufficient use of the volunteer staff. Gaps in this area of research are identified and topics for further research are presented.     

Utilitarian,hedonic, collecting,epistemic, and high values as determinants of the attractiveness of premium promotions

Modern retail is fiercely competitive, forcing grocery retailers to enhance promotions including premium redemption to attract customers. Taiwan’s leading convenience store chains have even established an integrated marketing department to develop unique premium rewards and campaigns that seek to induce customers to spend more or switch from other retailers. However, research on premium attractiveness is relatively scarce despite its importance in determining the success of a premium promotion. This empirical study identifies the premium value hierarchy that drives attractiveness from the consumer’s perspective. It finds that epistemic value is the most important driver behind making a premium reward attractive, which in turn, raises customers’ brand attitude toward the retailer and purchase intention in the retailer’s stores. High premium value can also make a customer develop a positive brand attitude. By contrast, utilitarian, hedonic, and collecting values only indirectly affect a customer’s brand attitude via the epistemic value. In addition, the trading stamps promotion only works with frequent customers; it is not effective in enticing VIP customers. This study provides suggestions on how to develop an attractive premium product and successful trading stamps promotion.     

Food,literature, art,and the demise of dualistic thought

In the early 1990s philosopher Deane Curtin proposed a “food‐centered philosophy of human being,” whereby food became a potential site for the elimination of the self/other duality so central to Western thought. Since food is ingested and becomes part of the self, it obliges us to reconceptualize not only the other but also the identity of a self that is so permeable, it can physically incorporate the other. Food/cooking/eating as a conceptual complex has further challenged the self/other dichotomy in barrier‐breaking new cultural artifacts such as “food books,” performance art pieces, and popular film.     

Age,order of entry,strategic orientation,and organizational performance

This paper proposes an empirical test of several hypotheses linking age, order of entry, and strategic orientations to a firm's performance. Three strategies are defined: cost-leadership strategy, innovative differentiation, and marketing differentiation. The aim is to show that the impact on performance of both age and each of the three strategic orientations may differ according to a firm's order of entry into an industry.Following Lieberman and Montgomery's (1998) evaluation of their major contribution on first mover advantage, we emphasize three points. First, we develop and test hypotheses related to early and late followers' strategic orientations, broadening the scope of traditional studies on pioneers. Second, the model combines the dimensions of a firm's age, order of entry, and strategic orientations, as well as industry conditions (stage of the industry, environmental unpredictability, and technology diffusion), to establish a contingent model of performance analysis. Finally, the empirical study deals chiefly with organizational performance and not market share, which is considered a typical advantage accruing to pioneers.In addition, the scope of the study (582 French manufacturing firms) provides the means to fill a void in empirical studies because it is a broad cross-sectional test on non-U.S. data. The firms are mainly private, small to medium-sized, and single or dominant business firms. Therefore, our assumptions must be understood as particularly applicable to this type of firm.The results reveal important lessons for practitioners. First, we did not find a first-mover advantage in terms of organizational performance. In addition, pioneers' organizational performance is enhanced by the cost leader strategy—contrary to our assumption emphasizing innovative differentiation for these firms. Second, early followers' performance benefits from innovative differentiation and marketing differentiation. Finally, late entrants developing a cost leader strategy have a significantly higher performance. All groups considered, late followers are the firms most sensitive to environmental uncertainty and age effects.Our study clarifies the impact of a firm's age and strategic orientations on its performance depending on the firm's order of entry. The implications of these results are particularly relevant for practitioners and entrepreneurs. First, a cost leadership strategy seems to be a guarantee for a pioneer to increase its organizational performance. New ventures should therefore take into consideration the fact that newness and innovative differentiation might not be the best strategic orientations for high performance in the long run. Second, as a second mover, however, developing a superior product and being able to market it efficiently appear to be the enhancing factors of firm performance. Third, for both pioneers and early followers, age does not significantly reduce their performance. However, the longer a firm waits before entering, the greater is the negative effect of age on its performance. This is due to the difficulty of resisting competitive erosion, because pioneers and early followers drive the changes in the industry. The identification of these effects should help managers and stakeholders to make more effective entry decisions to sustain a firm's advantage, leading to better performance and higher probability of survival.     

Managers,values, and executive decisions: An exploration of the role of gender,career stage,organizational level,function, and the importance of ethics,relationships and results in managerial decision-making

A study of 513 executives researched decisions involving ethics, relationships and results. Analyzing personal values, organization role and level, career stage, gender and sex role with decisions in ten scenarios produced conclusions about both the role of gender, subjective values, and the other study variables and about situational relativity, gender stereotypes, career stages, and future research opportunities.

Determinants,Structure, and Impact of Privatization

Summary

The focus of the paper are determinants of the rate and structure of privatization processes and thus the impact of privatization as exemplified by the case of Poland seen from the comparative perspective. The determinants can be grouped into the main factors, that is those not affecting the privatization processes directly (e.g., macroeconomics issues) and privatization-specific factors (directly affecting the process). The paper tries to dispel some popular and persistent myths concerning the impact of privatization and other transition processes.     

Globalization of Faculty,Students, and Programs

ABSTRACT

The objective of this paper is to develop a comprehensive approach to globalization of the educational effort in business colleges that is meaningful within the context of available resources and public funding. More specifically, the objective is to inventory approaches that have been used in the past to produce successful results and introduce new approaches more suitable to present needs. This strategy proposes that a successful globalization effort relies on three fundamental concepts: (1) strong commitment from the administration on all levels of the university; (2) strong leadership from faculty to develop, operationalize, and manage the globalization effort; and (3) clear encouragement of interested students and commitment from administration and faculty that they will benefit from their participation in the globalization effort of the university.

Adequacy,Accessibility, and Goodness of Data

ABSTRACT

The impact of information technology in the industrialized world is dramatic and the trend is continuing at an exponential rate with global implications. In contrast, the impact of information technology in developing countries is marginal, with only a few countries daring to travel on the information superhighway. One fundamental reason for the lag in the utilization of information technology in developing countries is the absence of basic data. This article explores the possible causes of this lack of basic data by examining the normative factors, cultural and exotic, embedded in the current practices of collecting, storing, and accessing data in Ghana, a developing country.

We also discuss the importance of goodness of data (i.e., accuracy, reliability, and validity of data) and the practices that compromise them. We then suggest ways by which information technology can be used to (1) address the goodness of data, (2) solve the problems associated with the current practices of recording, storing, and accessing data, and (3) enhance decision making in policy formulation and strategic planning.
