Emerging themes in distance learning research and practice: some food for thought

With the rapid spread of distance learning as a medium for delivering instruction, the practice of distance learning has outpaced research. This paper describes major themes identified in a review of selected research papers published in the past five years. Themes include the following: definitions of distance learning and why it should be studied; identification of the major learning theories on which research is based; how collaboration can be achieved via distance learning; the role that learner characteristics play in the success of distance learning systems, and issues related to measuring the effectiveness of distance learning. The authors conclude that more research is needed to identify critical success factors for distance learning.     

A collaborative effort to apply ergonomics to electric utility workers at generating stations

As part of a collaborative approach involving electric utility companies, university researchers, individual contractors and a not-for-profit research institute, two ergonomics teams consisting of skilled utility workers and trained ergonomists, were assembled. These teams were to identify tasks with risk factors for musculoskeletal disorders (MSDs) among workers in fossil-fueled generating stations and and to propose ergonomic interventions for these tasks. One team focused on tasks of electricians and the other focused on tasks of plant operators and mechanics. Several of the tasks were tested in an ergonomics laboratory and at one of the utility's generating stations. We present a sample of the recommended interventions in this paper. An anthropometric analysis of electrical box height recommended the appropriate height for electrical boxes. The results of a field experiment showed that low rolling resistance wheels decreased the forces to initiate and sustain pushing a cart. The same experiment also demonstrated that the forces required to turn a cart with six wheels were lower than the forces equired to turn a cart with four wheels. A collaborative approach to ergonomics proved to be an effective method to identify and assess tasks that are problematic for workers and to develop best practices for these tasks in the electric power industry. This method could be used by other industries in their attempt to decrease the incidence, cost and severity of workplace MSDs.     

Corporate Citizenship and Managerial Motivation: Implications for Business Legitimacy

In 2000, Business and Society Review published a Special Issue of the journal to explore scholars’ ideas about how the practice of corporate citizenship would evolve in the 21st century. Contributors to the volume predicted a change in business motives for engaging in social initiatives, suggesting that managers would begin to see corporate citizenship as a strategic necessity to preserve organizational legitimacy in the face of changing social values. This article uses data from a study of corporate citizenship practices in over 500 Norwegian companies to explore the validity of the Special Issue predictions. We begin by reviewing the foundations of organizational legitimacy theory and examine recent research documenting the growing importance of corporate citizenship for assessments of business legitimacy. We describe our study methods, present our results, and discuss the implications of our findings in this context.
