Managing green productivity: Some strategic directions

The twentieth century has been the hallmark for managing total productivity, where the emphasis is towards maximization of outputs commensurate with the consumption of inputs. This is being challenged now to evolve the world class manufacturing strategy requiring a paradigm shift. This shift is towards green productivity, which looks forward to socially appropriate production and consumption aiming at value innovation and resource conservation. This paper is an attempt to outline the concepts and experiential learning about green productivity.     

Layered supervisory control architecture for reconfigurable automation

The development of control systems and supporting software remains one of the greatest obstacles to the widespread implementation of highly adaptive reconfigurable automation technology. This paper will present the structure of a modular automation control system designed to support rapid reconfiguration and redeployment of automation components. The paper will first present the concept of a layered system architecture and the use of modular automation components to support the construction of a wide variety of automated systems. This layered system architecture is then applied to the proposed modular supervisory control system responsible for configuring and driving automated production resources. Each of the control components comprising this modular control system will be presented.     

Participation satisfaction and organizational commitment: moderating role of employee's cultural values

This paper explores the moderating role of cultural values on relationships between participation satisfaction (PS) and employees’ organizational commitment (OC). A survey of 1390 employees of Bharat Sanchar Nigam Limited, a Government of India Public Sector Undertaking providing telecommunication services across India, shows that PS is directly related to OC, and is moderated by employees’ cultural values at individual level. The form of moderation reveals: positive and insignificant relationship between PS and affective commitment for employees high in uncertainty avoidance; positive and significant relationship between PS and normative commitment for employees high in individualism/collectivism, low in masculinity/femininity, and low in power distance. No moderation has been found in the relationship between PS and continuance commitment.     

The role of tourism in national human resource development: a Jamaican perspective

Research in the national human resource development (NHRD) field is increasingly considering unique cultural and economic conditions and the influence this may have on a number of employment-related indicators. To date, the NHRD literature has largely ignored issues related to skills training and workforce development in the tourism industry, despite the expanding nature of this dynamic service sector in many nations. This literature review study of NHRD in Jamaica examined ongoing national-level human resource development (HRD) initiatives with specific attention to the current and future impact of NHRD on the tourism industry. The results showed that governmental development plans clearly identified tourism as a key sector for economic growth to support larger economic and social development goals. Furthermore, the development of human resources in the tourism sector was seen as being of vital importance for tourism organizations and for the continued development of Jamaica. The existing NHRD literature has largely overlooked the potential influence and future role of the tourism industry to assist in education, training and development goals at the national level. Recommendations are made for additional research exploring connections between NHRD and tourism employment.     

Further specification of the leader political skill–leadership effectiveness relationships: Transformational and transactional leader behavior as mediators

The present investigation was a three-source test of the intermediate linkages in the leader political skill–leader effectiveness and follower satisfaction relationships, which examined transformational and transactional (i.e., contingent reward behavior) leader behavior as mediators. Data from 408 leaders (headmasters) and 1429 followers (teachers) of state schools in the western part of Germany participated in this research. The results of mediation analyses, based on bias-corrected bootstrapping confidence intervals, provided support for the hypotheses that political skill predicts both transformational and transactional leader behavior, beyond other established predictors, and that transformational and transactional leader behavior mediate the relationships between leader political skill and leadership effectiveness. The contributions to theory and research, strengths and limitations, directions for future research, and practical implications are discussed.     

Followership,leadership and social influence

Traditional research in leadership has largely relegated followers to the role of passive recipients or, at best, moderators of leader influence and behaviors. However, recent work in the area of followership has begun shifting this focus and emphasizing the possibility that followers actively have an influence over leaders, in particular leader behavior. This paper revisits traditional areas of the leadership literature and builds on the emerging followership literature to reintroduce followers as part of the social context of leaders. In an attempt to build theoretical rationales for how followers influence leader behavior we draw on the social influence (e.g., Social Impact Theory, Latane, 1981) and the power literature to suggest individual (e.g., strength and immediacy of followers) and group level (e.g., number of followers and unity of the group) characteristics that influence leader behaviors as a function of a leader's informational and effect dependence on followers.     

Leader political support: Reconsidering leader political behavior

Historically, organizational politics and political leader behavior have been framed and characterized negatively, as self-serving and counter-productive. However, scholars have noted that political acts can achieve positive ends, and have called for further discussions of positive forms of political leadership. Continuing in this recent stream of research on positive perspectives on organizational politics, a framework of leader political support is proposed, suggesting that the positive features of leader political behavior, and testable propositions are developed. The leader political support construct is defined and its antecedents are explicated utilizing a social capital perspective. Additionally, social exchange theory is used to explain the consequences of leader political support. Contributions to both leadership and organizational politics literatures and directions for future research are discussed.     

The Competitive Impact of Targeted Television Advertisements Using DVR Technology

Digital video recorders (DVRs) are an emerging technology that is fundamentally changing the competitive landscape in industries that advertise on television. Perhaps the most familiar impact of DVR technology is that it enables consumers to avoid advertisements (ads) by fast forwarding through them. However, this “zipping” of ads is only one aspect of the impact of DVR technology. DVRs also collect a wealth of information at the consumer level that can be used by firms to target their ads more effectively. We examine how this targeting capability moderates the impact of ad avoidance in a competitive setting. Insights are provided on how best to manage this emerging technology in terms of the key managerial decisions of product pricing and advertising efforts, as well as its impact on profits in a competitive (duopoly) marketplace.     

Finding and Implementing Energy Efficiency Projects in Industrial Facilities

This study addresses the challenges of finding and implementing profitable energy efficiency (EE) projects, a critical foundation for sustainable operations. We focus on manufacturing enterprises, but many of our findings apply also to the back office of service operations. Our starting point is that, in nearly every industrial enterprise, there are many profitable EE projects that could be implemented but are not. An oft‐cited hindrance to implementation is the lack of an internal management framework in which to find, value, and execute these projects. Using a conceptual approach, we rely on proven sustainable operations tools to develop such a framework. We identify three major value drivers of EE projects: savings intensity, “green” image, and project complexity. We then describe a framework for understanding the context of EE projects in industry, with an underlying analytic foundation in optimal portfolio analysis. A case study of a large manufacturing site is used to illustrate emerging best practices—based on Kaizen management principles—for integrating EE project management with operations, engineering, and strategy.     

Sentiments

This paper develops a new theory of fluctuations—one that helps accommodate the notions of “animal spirits” and “market sentiment” in unique‐equilibrium, rational‐expectations, macroeconomic models. To this goal, we limit the communication that is embedded in a neoclassical economy by allowing trading to be random and decentralized. We then show that the business cycle may be driven by a certain type of extrinsic shocks which we call sentiments. These shocks formalize shifts in expectations of economic activity without shifts in the underlying preferences and technologies; they are akin to sunspots, but operate in unique‐equilibrium models. We further show how communication may help propagate these shocks in a way that resembles the spread of fads and rumors and that gives rise to boom‐and‐bust phenomena. We finally illustrate the quantitative potential of our insights within a variant of the RBC model.
