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.     

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.     

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.     

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.     

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.     

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.     

Developmental management: Theories,methods, and applications in entrepreneurship,innovation, and sensemaking

This paper summarizes the best papers of the Global Innovation and Knowledge Academy (GIKA) conference, which took place in July 2013 in Valencia, Spain. The Journal of Business Research has published a special issue entitled “Developmental management: Theories, methods, and applications in entrepreneurship, innovation, and sensemaking”. All of them went through many rounds of double-blind reviews and revisions. Theories, methods, and applications are the three pillars to solve the issues in entrepreneurship, innovation, and sensemaking. Entrepreneurship contributes to the quality and future hopes of a sector, economy or even a country. The role of the entrepreneurs is crucial in creating value. Innovation has become important as the global economy seeks to escape from a period of major recession. In organizations, sensemaking consists of cognitive strategies for interpreting reality. It is interesting to examine how these three issues interacting with each other. And these papers contribute to various perspectives of these interactions in different countries.     

Trust disposition,trust antecedents,trust, and behavioral intention

Trust is important for fostering successful relationships, reducing uncertainty and risk, and increasing willingness to purchase. This study tests the replications in the mobile banking (m-banking) industry and the influence of trust on purchase intention via investigating the relationships between disposition to trust, and trust antecedents to trust in forming trust in m-banking services, which in turn leads to behavioral intention to adopt those services. In spite of numerous studies being focused on the critical role of trust in recent decades, the topic of multidimensional trust antecedents in m-banking, as well as the effects of disposition to trust on m-banking adoption intention has been relatively neglected. Based on the data collected in Taiwan, the results reveal significant positive relationships between disposition to trust, trust antecedents, and trust. Meanwhile, the relationship between trust and behavioral intention are positively significant. Contributions and managerial implications are discussed.     

The relationship among gratitude,hope, connections,and innovativeness

The interwoven relationships among positive emotions and connections among people within the organization, manifested as collective gratitude and hope, and high-quality connections (HQCs), and firm service innovativeness and financial performance have rarely been addressed in the service innovation management literature. By studying 251 service firms, this paper shows that (a) collective gratitude is positively related to development of HQCs among people within the organization and firm service innovativeness, (b) HQCs among people within the organization are positively associated with firm service innovativeness, and (c) firm service innovativeness is positively related to firm financial performance. This paper also demonstrates that the collective hope of people within the organization positively moderates the relationship between collective gratitude and HQCs among them.     

Emotions, store-environmental cues, store-choice criteria, and marketing outcomes

This study integrates extant research relating to store-related cognitions, customer emotions (arousal and pleasure), satisfaction, and loyalty into one framework. The researchers administer a survey to 274 customers in four coffee shops of a major chain. Using these data, the researchers test the hypotheses and model with structural equation modelling. The findings suggest that (a) store-related cognitions differentially affect emotions and customer outcomes (satisfaction and loyalty) and (b) the two emotions of arousal and pleasure differentially mediate the relationships between store-related cognitions and customer outcomes.     

Entrepreneurship, innovation, and corruption

Efforts to control corruption increase levels of trust in the ability of the state and market institutions to reliably and impartially enforce law and the rules of trade. Such trust facilitates the development of arms-length trade and the coordination of complex economic activities. We posit that better control of corruption will also be associated with rising levels of innovation and entrepreneurship. Absent such trust, however, monitoring and other transactions cost should restrict the scale and scope of trade and thus, hamper productivity and investment in innovation and entrepreneurship. Longitudinal data from 64 nations lends support to our propositions, thus helping unpack the puzzling relationship between entrepreneurship, innovation, and corruption.     

Inequality,Mobility, Real Earnings,and Real Anger

Understanding the anger among the electorate right now requires an examination of the relevant economic trends. Inequality has increased and real wage growth has been limited for the median worker, as the relationship between productivity and wages has broken down. Measures of wealth inequality have outstripped those for incomes. Higher levels of inequality are correlated with less upward mobility over the life span, have potential costly macro-growth impacts, and contribute to “sticky” poverty rates which hurt child outcomes. Even in recent decades, though, periods of full employment have seen advances in real earnings. Thus, to reconnect growth and more broadly shared prosperity we need full employment, better-targeted manufacturing policy, a strengthened safety net, a higher minimum wage, access to quality preschool, and reduced mobility barriers.     

个性、精准、互动、整合——数字电视对传统广告运作模式的挑战

在数字化技术发展应用背景下,数字化是电视发展的必然趋势。据有关数字显示,从2005年至2009年,全球数字电视用户数量每年保持30%的速度增长,全球数字电视用户将从2004年的11720万户增长到2009年的51600万户,全球数字电视市场规模也将从2004年的570亿美元增长到2009年的1040亿美元。     

HOPE,FEAR, AND ASPIRATIONS

We propose a rank‐dependent portfolio choice model in continuous time that captures the role in decision making of three emotions: hope, fear, and aspirations. Hope and fear are modeled through an inverse‐S shaped probability weighting function and aspirations through a probabilistic constraint. By employing the recently developed approach of quantile formulation, we solve the portfolio choice problem both thoroughly and analytically. These solutions motivate us to introduce a fear index, a hope index, and a lottery‐likeness index to quantify the impacts of three emotions, respectively, on investment behavior. We find that a sufficiently high level of fear endogenously necessitates portfolio insurance. On the other hand, hope is reflected in the agent's perspective on good states of the world: a higher level of hope causes the agent to include more scenarios under the notion of good states and leads to greater payoffs in sufficiently good states. Finally, an exceedingly high level of aspirations results in the construction of a lottery‐type payoff, indicating that the agent needs to enter into a pure gamble in order to achieve his goal. We also conduct numerical experiments to demonstrate our findings.     

Big data: Dimensions,evolution, impacts,and challenges

Big data represents a new technology paradigm for data that are generated at high velocity and high volume, and with high variety. Big data is envisioned as a game changer capable of revolutionizing the way businesses operate in many industries. This article introduces an integrated view of big data, traces the evolution of big data over the past 20 years, and discusses data analytics essential for processing various structured and unstructured data. This article illustrates the application of data analytics using merchant review data. The impacts of big data on key business performances are then evaluated. Finally, six technical and managerial challenges are discussed.     

Distance,production, and trade

Abstract

This paper investigates the relationship between geographical distance and both the extent of trade and foreign production. Industries engaged in exporting and co-production activities across national boundaries are identified through their use of the Offshore Assembly Provisions in the US tariff code. Findings counter conventional wisdom. Trade and foreign production activities are found to drop off rapidly over the first third of the distance scale, rise over the middle portion, reach a peak in the final third, and decline thereafter. This pattern suggests frictions associated with distance can be offset by government policies and other country attributes. Management control, information and communications costs, and the ability to implement just-in-time delivery strategies may not be as distance sensitive as previously thought. Theorists should re-evaluate the role of distance in trade models and refrain from using distance as a proxy for transport costs.     

Countertrade: Forms,motives, pitfalls,and negotiation requisites

The impressive growth in countertrade necessitates a careful look at this trade financing mechanism and a new attitude by American policy makers and businessmen toward it. This study looks at the various forms of countertrade, at the motivating forces behind it, at the pitfalls that countertrade could engender, and at some imperatives in the negotiation of countertrade deals. The issues are examined from the perspective of a policy maker and that of a businessman. The two perspective are distinct but overlap sufficiently to merit a joint examination. It is the conclusion of this study that countertrade is here to stay, and that American businessmen better learn to cope with it if they are to maintain and improve their competitiveness in the world markets.     

Interactions,innovation, and services

Although research has acknowledged the importance of supplier–buyer relationships for goods innovation, empirical evidence on the extent and nature of the effects of original equipment manufacturing (OEM) supplier–buyer relationships on service innovation remains scarce. Based on a survey of 152 suppliers in Taiwan, this study concludes that the interaction orientation of OEM suppliers is a key factor influencing the development of two competencies: joint innovation competence and cross-functional information dissemination competence. These two competencies contribute to OEM suppliers’ exploitative service innovation and explorative service innovation, respectively. In other words, applying a resource-based view, this study provides clarity regarding the linkages shown below (an organization’s strategic orientation influences its development of organizational capabilities and results in organizational performance) for the purpose of exploring the relationship between interaction orientation and service innovation.
