Contextual factors: assessing their influence on flow or resource efficiency orientations in healthcare lean projects

The outcomes of lean projects have been mixed, with some being successful while many others have not. An explanation for this is a paradox that can develop depending on the focus of the project. Ironically, in projects where the focus is on maximizing the efficiency of a resource (‘resource efficiency’), this focus might lead to worsening of the resource’s efficiency, thereby generating an ‘efficiency paradox’. This paradox does not usually arise in projects where the focus is on the subject of interest being processed through the system in the most efficient manner (‘flow efficiency’). The aim of this paper is to investigate the factors that give rise to either form of efficiency. We conducted a detailed study of eight lean projects in two large hospitals. In doing so, we advance the theory of lean service operations by identifying four key contextual factors that drive the orientation of a project to resource or flow efficiency. These are: service variety, interdependency, capital resource intensity, and service uniqueness. We propose a conceptual framework and four propositions that integrate the contextual factors to determine the dominant focus in lean projects. Through this, recommendations are made as to how the efficiency paradox can be avoided.     

The Tax Exemption to Subchapter S Banks: Who Gets the Benefit?

The Small Business Job Protection Act of 1996 allows U.S. banks to adopt the Subchapter S status. We investigate if the Subchapter S banks use tax benefits for the intended purposes of “protecting jobs,” “creating opportunities” and “increasing take home pay of workers.” We find that the tax benefits: (a) are not used in expenses related to protection of jobs, (b) do not lead to greater employment opportunities within the Subchapter S banks, and (c) do not benefit the employees in the form of increased salaries and benefits. Our results indicate that bank owners are sole beneficiaries of the tax exemption benefits.     

The two limits debates: “Limits to Growth” and climate change

In this article we compare the current debate about global warming with the earlier discourse of Limits to Growth (LtG) of the 1970s. We are especially interested in the similarities of and differences between the two cases and therefore compare the policy challenges and lessons to be drawn. While the two debates differ on important issues, they share a technocratic orientation to public policy, and susceptibility to similar pitfalls. In both debates alarming scenarios about future catastrophes play an important role. We suggest that climate change policy discourse needs to focus more closely on the social, economic, and political dimensions of climate change, as opposed to its excessive emphasis on emission reduction targets. We also argue that an excessive faith in the market mechanisms to supply global warming mitigation technologies is problematic. In this respect, we provide a reality check regarding the political implications of emission targets and timetables and suggest how policy issues can be moved forward.     

Does knowledge of finance mitigate the gender difference in financial risk-aversion?

We investigate the gender difference in financial risk aversion using a survey of finance professors from universities across the United States. We compare their actual portfolio allocations to that of respondents in the Federal Reserve's Survey of Consumer Finances (SCF). We find that among highly educated individuals, women are significantly more risk averse than men. However, we find that when men and women have both attained a high level of financial education, they are equally likely to invest a significant portion of their portfolio in risky assets, suggesting that financial education mitigates the gender difference in financial risk aversion.     

Forest carbon benefits,costs and leakage effects of carbon reserve scenarios in the United States

This study evaluated the potential effectiveness of future carbon reserve scenarios, where U.S. forest landowners would hypothetically be paid to sequester carbon on their timberland and forego timber harvests for 100 years. Scenarios featured direct payments to landowners of $0 (baseline), $5, $10, or $15 per metric ton of additional forest carbon sequestered on the set aside lands, with maximum annual expenditures of $3 billion. Results indicated that from 1513 to 6837 Tg (Teragrams) of additional carbon (as carbon dioxide equivalent, CO₂e) would be sequestered on U.S. timberlands relative to the baseline case over the next 50 years (30–137 Tg CO₂e annually). These projected amounts of sequestered carbon on timberlands take into account projected increases in timber removal and forest carbon losses on other timberlands (carbon leakage effects). Net effectiveness of carbon reserve scenarios in terms of overall net gain in timberland carbon stocks from 2010 to 2060 ranged from 0.29 tCO₂e net carbon increase for a payment of $5/tCO₂e to the landowner (71% leakage), to 0.15 tCO₂e net carbon increase for a payment of $15/tCO₂e to the landowner (85% leakage). A policy or program to buy carbon credits from landowners would need to discount additions to the carbon reserve by the estimated amount of leakage. In the scenarios evaluated, the timber set-asides reduced timberland area available for harvest up to 35% and available timber inventory up to 55%, relative to the baseline scenario over the next 50 years, resulting in projected changes in timber prices, harvest levels, and forest product revenues for the forest products sector.     

From the Global to the National Cycle: An Intricate Liaison

This paper examines the linkages between the global business cycle and national cycles. We first analyse the evolution of the global business cycle and present its main properties during global recessions and recoveries. We then consider how the sensitivity of national cycles to the global cycle varies over different phases of the global cycle and depends on country‐specific features. Our findings collectively portray an intricate liaison between the global business cycle and national cycles. National business cycles are tightly linked to the global cycle, but the sensitivity of national cycles to the global cycle is much higher during global recessions than expansions. There are significant differences across countries in how they respond to the global cycle as advanced economies appear to be more sensitive to global recessions than are developing economies. Moreover, countries tend to be more sensitive to the global cycle, the more integrated they are to the global economy.     

Managerial Perceptions of Information Technology and their Impact from a Transaction Cost Perspective

This article addresses the questions of how hotel managers perceive the impact of information technology (IT) on hotel service operations, particularly transaction costs, and whether its impact on these costs affects the decision-making framework. A multiple case study approach using a two-stage interview process was adopted. This comprised a closed, fixed-response questionnaire administered to a group of managers followed by a standardized, open-ended interview intended to capture both objective and subjective views. Although the managers objectively identified a positive impact for IT, their subjective views indicated that this impact is only superficial. This gap points to the existence of bounded rationality in managerial decision making about state-of-the-art IT systems.     

A relational perspective to knowledge creation: Role of servant leadership

Knowledge creation is a dynamic activity where new ideas and meanings are created through coaction and interactive relationships. However, due to overemphasis on competitive spirit and individualistic orientation, knowledge organizations ignore the significance of people and relationships. Extending a relational perspective, this article proposes a model of servant leadership for facilitating knowledge creation through sharing leadership responsibilities with followers resulting in mutual influence and direction, and inculcating caring relationships. It ensures greater exchange of ideas, experiences, and expertise between servant leaders and followers that result in the generation of new knowledge. By constructing this model we have explained various processes with several propositions showing relationships between servant leadership and shared leadership, shared leadership and knowledge creation, servant leadership and caring relationships, and caring relationships and knowledge creation.
