An evolving medical leadership position. Tomorrow's Vice President for Medical Affairs

The role of medical leadership in hospitals and health systems is under constant scrutiny and change. The nature of the Vice President for Medical Affairs (VPMA) position and its relationship to leadership in the health care system is explored through a national panel survey conducted recently. The effective VPMA will: be an aggressive manager able to implement change, address strategic planning and quality of care issues; have a high level of integrity; and be a good communicator and problem solver. The results of the research are presented in three sections. The first section describes the background characteristics and compensation of the VPMAs who participated in the survey. The second section focuses on the current role of the VPMA, including duties and responsibilities, job performance barriers and required skills. The final section addresses respondents' perceptions regarding areas for improvement in the role of the VPMA, as well as projections for future changes in this position.

A goal programming model for paper recycling system

The conflict between economic optimization and environmental protection has received wide attention in recent research programs for waste management system planning. This has also resulted in a set of new waste management goals in reverse logistics system planning. The purpose of this analysis is to formulate a mixed integer goal programming (MIGP) model to assist in proper management of the paper recycling logistics system. The model studies the inter-relationship between multiple objectives (with changing priorities) of a recycled paper distribution network. The objectives considered are reduction in reverse logistics cost; product quality improvement through increased segregation at the source; and environmental benefits through increased wastepaper recovery. The proposed model also assists in determining the facility location, route and flow of different varieties of recyclable wastepaper in the multi-item, multi-echelon and multi-facility decision making framework. The use of the model has been illustrated through a problem of paper recycling in India.     

The Aston Programme Contribution to Organizational Research: A Literature Review

This paper reviews the literature about the Aston Programme of organizational research, in particular, its studies of organizational structure. The intellectual commitments of the Aston Programme are explicated and contrasted with the then dominant traditions of organizational research. The methodology is explained, with its emphasis on quantitative variables, reliable scales and statistical methods. The way successive studies confirmed or challenged Weberian bureaucracy is discussed. The major structural scales and their short forms are described. The relationships among the structural variables and between them and the contextual variables of size, technology and public accountability are outlined. The generalizability of these relationships in organizational research across countries is considered. The paper offers a roughly chronological narrative in three phases: the original Aston study, the National study and then on to the many subsequent replication and extension studies and reviews of them. Some cognate organizational research studies are brought in that confirm the Aston Programme. The need to continue the Astonian Cartesian approach rather than the configurational approach is emphasized. In closing, the Aston legacy is briefly summated and a vision for a future Aston Programme is offered in an Epilogue.     

Integrating regional and functional plans at Henkel

The article describes the planning system of the Henkel KGaA. The company is completely family owned. It is the fourth largest chemical company in Germany with affiliated companies nearly all over the world. The product range consists of consumer good articles such as detergents, cosmetics, household cleaners and adhesives and a wide range of chemical specialities which are sold to industry. The turnover world-wide is nearly DM7bn. The planning system of the Henkel KGaA is constructed in such a way that despite the necessity of short-term control the longer-term perspective still remains the basis for decision making. The planning structure and process throughout the company are explained in detail. The authors show that this system is an investment in managerial information processing.     

The dynamic performances of DDTs in the environment and Japanese exposure to them: a historical perspective after the ban.

The fugacity model for evaluating DDTs dynamic performances in the environment was combined with the dietary exposure evaluation model, including the contribution of imported food, to develop the macroscopic mathematical model relating DDTs in the environment with the health risks of the reference Japanese. The model validity was examined by comparing the simulated DDTs concentrations in environmental media, various kinds of food, and dietary intake with those observed. Numerical simulations were done for the past half and future of one century to evaluate the effect of the DDTs usage prohibition in 1970 in Japan. The major results obtained under the limits considered are as follows. The DDTs concentrations in environmental media, various kinds of foods, and the dietary intake showed the steady exponential decrease after the DDTs usage prohibition in 1970. The DDE/DDTs ratio is larger in the higher position in an ecological system, and increased steadily with time. The critical exposure of DDTs occurred through animal product intake until 1960; after 1990 marine product intake caused the most exposure. The estimated DDTs intake was evaluated to be less than the PTDI and RfD. The annual excess cancer induction risk due to the annual dietary intake of DDTs was the largest at the level of (0.5 - 2.0) x 10(-6) (1/yr) in the early 1970s. The effect of the DDT usage prohibition on dietary exposure reduction was expected to appear after about 20 years. The life-span excess cancer induction risk was conservatively estimated to be larger than 10(-5) (1/lifespan) for the reference Japanese who were born before 1970. The DDTs usage prohibition in 1970 was effective to reduce the life-span cancer risk under the 10(-5) level.

Interorganizational Collaborative Forecasting and Replenishment Systems and Supply Chain Implications

Collaborative Forecasting and Replenishment (CFAR) is a new interorganizational system that enables retailers and manufacturers to forecast demand and schedule production jointly. The capabilities of CFAR exceed those of the traditional EDI because CFAR allows exchange of complex decision support models and manufacturer/retailer strategies. The proponents of CFAR claim that the fastest way for retailers and manufacturers to slash inventory costs and product shortages is by coordinating their decisions. The impact of CFAR on the supply chain using a model consisting of a manufacturer selling its product through two independent identical retailers is analyzed. The model assumes that the manufacturer doesn't face capacity constraints, the demand is stationary, and retailer prices are constant over time; the shortages are backordered at the manufacturer and retailers to isolate the effects of information sharing in CFAR. The most significant findings relate to the increase in the cost incurred by the nonparticipant in CFAR, the increase in the manufacturer's cost of serving the nonparticipant if the participant can obtain delivery guarantees in return for demand information sharing, and the incentives of the players to move towards universal retailer participation in CFAR. The findings are explained using the risk structure faced by the players in the supply chain. The managerial implications of the impact of CFAR on the supply chain structure are also discussed.     

THE IMPACT OF TAX POLICY ON INVESTMENT BEHAVIOR IN THE CHEMICAL INDUSTRY, 1951-65

The purpose of this study was to estimate the impact of changes in Federal tax policy on investment behavior in the chemicals and allied products industry and to examine the possibility of a differential impact of changes in tax policy on investment behavior in manufacturing industries. The impact of changes in tax policy on investment behavior in the chemical and allied products industry was estimated and compared with the impact of tax policy on investment behavior in total manufacturing found in earlier studies. The model used to estimate the impact of changes in tax policy on investment behavior in the chemicals and allied products industry was the neo-classical model of capital accumulation as formulated initially by Dale Jorgenson. The conclusions reached were that changes in tax policy have had a measurable impact on investment behavior in the chemical and allied products industry which was greater as a percentage of gross investment than that found on total manufacturing in earlier studies.     

Can the Level of Employment be Explained by GDP Growth in Transition Countries? (Theory versus the Quality of Data)

This paper presents a survey on the relationship between growth and employment in selected transition economies. The second section discusses the empirical evidence using two sets of recent data on employment and pays special attention to gender inequality in economic activity. The third section provides an overview of the literature on the causes of the behaviour of employment and output in transition countries. The fourth section tests the response of employment to GDP growth using data from 11 years and 11 countries. The main result of the paper shows that there seems to be no relationship between output growth and the level of employment in the post‐transition period for two countries: Bulgaria and Ukraine. The fact that both countries have one of the highest shares of unofficial economy in total output in the region is suggested as the main explanation behind this striking result.

Die Rahmenbedingungen verändern sich — der Dritte in der Therapie

The background conditions are changing — the third party in therapy The author examines connections between dyadic and triangle structures in the rehabilitation of addiction diseases. He considers the background of his personal experiences related to the changes in his professional position. The traditional dyadic relationship between physician and patient becomes ?destroyed“ by an triangle system in the frame of rehabilitation. Only by reflecting the job order it becomes possible to hold the balance between the responsibilities regarding the patient, the institution, the financial supporter and oneself. The difficulties in this process are reflected (overestimation of oneself and/or of others resp. devaluation of oneself and/or of others). The author explains the necessity to learn, to respect and to estimate, what one has not learned and does not fit to one’s self-understanding.     

Designing effective team-based performance measurement systems: an integrated approach

Measuring the performance of teams and, in particular, designing effective team-based performance measurement systems (TPMS) can be a difficult task. The purpose of this paper is to take the reader through the development and testing of a construct that provides an integrated approach to facilitate the design of TPMS. This construct was developed and tested based on a rigorous set of criteria adopted from constructive research theory as well as from existing performance measurement literature. The construct was tested in a series of workshops described in this paper. The data gathered during these workshops demonstrates the novelty and validity of the construct. The paper should be of interest to managers, team leaders and indeed anyone who is interested in monitoring and managing team performance. The paper will also be of interest to academics working in the fields of performance measurement and team management.     

Long range planning of U.K. and Japanese corporations—A comparative study

The author conducted mail surveys on long-range planning systems in Japanese and British corporations. He also made a number of visits to corporations in both countries to analyse the similarities and differences in the planning systems.In the U.K., the clarification of goals and the resource allocation are emphasized but in Japan clarification of goals and basic problem finding are stressed.The strategic projects are not necessarily formulated in the long-range planning process. The relationship between the project and the long-range planning was analysed and in both countries, the trend of long-range planning is towards more strategy orientation than quantitative computation.The planning process in Japan is more centralized. The management committee plays an important role in reviewing and making the final decision. In the U.K., the plan initiation is more decentralized, and in the final decision the board of directors plays a more important role. The trends are, however, from bottom up approach to top down approach.Goals expressed in the long-range plan of the U.K. corporations put more emphasis on financial goals, but that of the Japanese corporations emphasizes growth and employee welfare.Regarding the style of strategic decision-making the subjective responses show that it is partly analytical and partly intuitive. There are some differences between two countries, but this problem needs to be analysed further.To cope with uncertainty, multiple scenarios and contingency plans are more frequently used in the U.K., whereas in Japan the sequential decision is more commonly used. British corporations are better prepared for uncertainty than Japanese corporations.The key success factors of long-range planning are similar in both countries. The involvement of top management and cooperation of line management are two important items. Differences are that in the U.K. the planning system is emphasized in addition to the other factors, but in Japan clear goals are more emphasized.     

Relationship between job control, work pressure and strain: studies in the USA and in The Netherlands

The purpose of this study was to test a model of job control, work pressure and strain in two samples in the USA and in The Netherlands. According to the proposed model, work pressure has a mediating role between job control and worker strain. The present model specifies three types of job control: task or instrumental control, conceptual or resource control, and decision organization control. Task and resource control are assumed to reduce the stressor of work pressure which, in turn, is related to high strain. Organization control is assumed to be positively related to work pressure. The model was tested in two samples : one US sample of 273office employees and one Dutch sample of 958 employees in a variety of jobs. The same measure of job control was used in both samples. Resultspartially confirm the proposed model. As predicted by the proposed model, high task control was related to low work pressure, whereas high organization control was related to high work pressure. The effects of task control and organization control on strain were mediated by work pressure for the measure of anxiety in the US sample and for the measure of stress in the Dutch sample. However, the mediating effect of work pressure was not found for job satisfaction in both samples, for the measure of mood disturbances in the US sample and for the measure of sick days in the Dutch sample. The proposed model is only partially confirmed by the results. These results confirm the importance of differentiating between different dimensions of job control.     

Applying fuzzy logic to personnel assessment: a case study

The main results of a research project spanning over several years are presented in this paper. The aim of the research was the improvement of the effectiveness of personnel assessment within a large Italian corporation operating in the research sector. The first step of the research consisted of the analysis of the raters’ behavior, so as to elicit the judgement categories and prototypes they used in the judgement formulation, based on the rating method adopted in the corporation. The second step consisted of improving the rating method using fuzzy logic. The corporate management tested the new rating method and found it more efficient and reliable than the previous one.     

Public Response to the Tokai Nuclear Accident

This article discusses the influence of the September 30, 1999 nuclear accident in Tokai village (Japan) on the public's attitudes toward nuclear power in Japan. The data used in this report were taken from the results of two surveys conducted mainly to measure the attitudes of the Japanese public with regard to the use of nuclear power in Japan. The first survey was done before the accident in District 23 in Tokyo and also in Osaka and Nagoya. The second survey, which took place after the accident in District 23 in Tokyo and in Osaka and Nagoya, also included residents in a number of other cities of various sizes throughout Japan. The results of the two surveys showed that (1) acceptability of and trust in nuclear power operation had decreased, (2) perceived accident likelihood and public interest had significantly increased, and (3) there had been neither significant nor even a small change in the public's self-rated knowledge about nuclear power or their distrust of the government. The results also showed that the ratio of nuclear power generation opponents to total respondents had considerably increased (7% to 23%) whereas nuclear power generation supporters had moderately decreased (1% to 12%).

Societal Risk Perception and Media Coverage

The study compares societal risk ratings by inhabitants of two countries which differ markedly in terms of geography, economics, politics, and ethnic background, but which are similar as regards media coverage. The two populations were represented by a sample of French students and a sample of Burkina Faso intellectuals. The overall Burkinabè mean ratings appeared much closer to the mean observed in France (and in the United States–roughly 40 out of 100) than the means reported for other countries like Norway or Hungary. The correlation between Burkinabè and French ratings was very high:.852. The findings argue in favor of a practically totally determinant effect of the media in risk perception.
