Rethinking managership,leadership, followership,and partnership

Organizations underperform, or fail, when members avoid partnering with managers—whether through subtle resistance, disagreement, protest, or walkout—to achieve common purpose. Managers should boost partnering not by affecting a pretense of leadership but through a nuanced balance of managerial authority and understanding of members’ points of view. The objective of this article is to sharpen attention on the concept of partnership with organization members and how it relates to some of the important previous literature. We also argue that some of the previous scholarly work contributes to misconceptions related to these concepts. Our work is forward-looking in that it is motivated by the dangerous societal and cultural differences evident in the world, differences that surround management’s decisions and that may induce an overuse of authority to quash disquiet. Using our experiences in both industry and academia, we argue that the crucial link between managers and members is leadership—not leadership thought of as directional and inspirational, but leadership as building a relationship toward common purpose through partnership. “Lead” and “leader” are sorely misused terms, and worse, substituting “leader” for “manager” is just plain wrong. We believe that managers become leaders only when followers agree to follow, not when the managers simply step forward energetically with direction. Managers are cheated by mistaken definitions. Reviewing past perspectives about what makes good leaders and managers, we rethink ways to enhance organizational harmony through a clearer understanding of managership, leadership, followership, and partnership. Only by thinking and acting as partners in common purpose can managers and members form the core of success in organizational endeavors.

Convenience,Price, Product

Abstract

This study examines the factors motivating consumers' purchases of specialty food and beverage products via the Internet. While convenience is often cited as a motivating factor, price and product selection have also been identified. This study considered convenience in terms of time, space, and effort. It also identifies several specific sub-categories for price and products. Among respondents who had made a recent online purchase, convenience-related issues were most frequently cited as being relevant to the purchase decision. Product-related factors were important for nearly one-third of the respondents. Price was of relatively little importance.     

Sustainability, Epistemology, Ecocentric Business, and Marketing Strategy: Ideology, Reality, and Vision

This conceptual article examines the relationship between marketing and sustainability through the dual lenses of anthropocentric and ecocentric epistemology. Using the current anthropocentric epistemology and its associated dominant social paradigm, corporate ecological sustainability in commercial practice and business school research and teaching is difficult to achieve. However, adopting an ecocentric epistemology enables the development of an alternative business and marketing approach that places equal importance on nature, the planet, and ecological sustainability as the source of human and other species’ well-being, as well as the source of all products and services. This article examines ecocentric, transformational business, and marketing strategies epistemologically, conceptually and practically and thereby proposes six ecocentric, transformational, strategic marketing universal premises as part of a vision of and solution to current global un-sustainability. Finally, this article outlines several opportunities for management practice and further research.     

Exports,borders, distance,and plant size

The fact that large manufacturing plants export relatively more than small plants has been at the foundation of much work in the international trade literature. We examine this fact using Census microdata on plant shipments from the Commodity Flow Survey. We show that the fact is not entirely an international trade phenomenon; part of it can be accounted for by the effect of distance, distinct from any border effect. Export destinations tend to be farther than domestic destinations, and large plants tend to ship farther distances even to domestic locations compared with small plants. We develop an extension of the Melitz (2003) model and use it to set up an analysis with model interpretations of ratios between large plant and small plant shipments that can be calculated with the data. We obtain a decomposition of the overall ratio into a term that varies with distance, holding fixed the border, and a term that varies with the border, holding fixed the distance. The distance term accounts for more than half of the overall difference.     

Dreams,fairy tales,animals, and cars

With growing interest in qualitative research beyond its popular use in focus groups, a greater appreciation of the potential of projective techniques is recommended. Examples are given to illustrate the variety of methods available, and how they may be practically applied in research projects to elicit rich information about perception of products and brands, and about characteristics of respondents.     

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.
