Distributed group support systems: Social dynamics and design dilemmas

A “distributed group support system”; includes decision support tools and structures embedded within a computer‐mediated communication system rather than installed in a “decision room.”; It should support groups who are distributed in space but not time ("synchronous”; groups), as well as “asynchronous”; groups whose members participate at different times. Pilot studies conducted in preparation for a series of controlled experiments are reviewed in order to identify some of the problems of implementing such a system. Many of the means used by groups meeting in the same place at the same time to coordinate their activities are missing. Embedding decision support tools within a different communications medium and environment changes the way they “work.”; Speculations are presented about software tools and structuring or facilitation procedures that might replace the “missing”; coordination channels.     

Coaching government and political leaders in complex environments

In the corporate world, leadership development programs are standard fare. Such programs often include well‐defined competencies and performance metrics, as well as regularly scheduled feedback and mentoring sessions, especially for those employees designated “high potential” performers. Not so in the public sphere. There are no defined career paths or standardized training curricula for heads of state. There are, however, requisite competencies for effective public sector leadership. As Gardner (1990) observed, “Leadership is not a mysterious activity. It is possible to describe the tasks that leaders perform....[But] we have barely scratched the surface in our efforts toward leadership development” (p. xix). The learning curve is steep for a newly elected leader, and fraught with potential landmines. Speaking with the candor of someone no longer seeking public office, former UK Prime Minister Tony Blair said recently, “When I came to office, prime minister was the only job I'd ever held; I'd never been a government minister before....The business of running a government is like anything else: You get better the longer you do it. And there are lessons out there that, had they come to me in an identifiable form, would have been useful to know” (talk given on December 16, 2010b). Both Gardner and Blair are emphatic that leadership is not something one is born with but something learned over time. And as Blair (2010a) put it, “Government is a race between expectations and capability.” In the essays that follow, several leadership coaches discuss the unique challenges and effective approaches they are using to help government leaders build the competencies that will enable them to govern effectively—and win that race between their constituents's expectations and their own capabilities.     

Oligopolies with (Somewhat) Environmentally Conscious Consumers: Market Equilibrium and Regulatory Intervention

We consider a horizontally differentiated duopoly where consumers care about the product's “greenness.” Firms can be asymmetric: they may differ in the product's intrinsic value and may also differ in their chosen level of greenness. We examine the choice of greenness and the implications of various policy interventions. We show that (i) the choices of product greenness are strategic substitutes, (ii) the high‐intrinsic quality firm produces the greener product, (iii) the low‐quality firm's greenness may increase with the cost of its provision or decrease with consumer willingness to pay for it, (iv) a minimum quality standard (MQS) leads the greener firm to lower its environmental quality and can even reduce average quality, (v) greenness is underprovided even if consumers fully internalize the externality, and (v) an MQS can reduce welfare if the greenness of the high‐quality firm exceeds the MQS, even when environmental quality is underprovided. The effects of policy interventions on profits differ qualitatively across polices and firms: A firm that lobbies for one type of intervention may lobby against another similar one, and a firm may lobby for an intervention while its competitor may lobby against it. A subsidy for the development costs of a green product can financially hurt both firms.     

Free To Choose? Dimensions of Private-Sector Wage Determination, 1979–1994

Deregulation of the system of pay determination in Britain was started in 1979 with the removal of incomes policy. The objective was to give employers the freedom to determine wage increases without the restrictions of pay norms or statutory limits. Instead, companies would be able to link changes in pay to the fortunes of the individual enterprise or establishment. By the mid-1990s, had these attempts to decentralize wage negotiations changed the determinants of wage settlement outcomes in Britain? We address the influence of industrial relations institutions and labour market pressures on wage increases between 1979 and 1994 using evidence from the CBI’s Pay Databank. Despite the direction of the Conservative Government’s policy, the external institutional forces of the labour market, particularly the rate of inflation and comparability, appear to exert an enduring influence, both qualitatively and quantitatively, on pay determination.     

ECONOMIES OF THROUGHPUT AND TRANSPORT BOTTLENECKS IN GRAIN DISTRIBUTION SYSTEMS

In this paper, a model is presented which shows the relationship between country grain storage costs and transport bottlenecks that exist in the harvest period. It is shown that transport bottlenecks limit the amount of grain that can be transported from receival points in the peak receival period. This constraint means that the cost of operating country receival points is high because the turnover of storage capacity is limited. However, system costs can be reduced by focusing the peak transport task at sites that are less intensive users of scare transport capacity. This allows more grain to be transported out of the system in the peak period, decreasing the need for costly long term storage at country sites. In the longer term, differences in the intensity of transport use means that optimal levels of investment in storage capacity (relative to grain receivals) will differ between sites. Relatively more storage should be constructed at sites that are intensive users of transport capacity (eg. those sites that are furthest from the port). Less storage capacity is needed at sites that are less intensive users of transport because a large depot-to-port transport task will be concentrated at these sites in the peak period.     

The language of business: a key nurse executive competency

The ability to interpret fiscal data pertaining to patient outcomes, human resources, customer satisfaction, and financial positions is a vital evidenced-based nurse executive competency. The ability of nurse leaders to influence and contribute in health system executive decision making requires fluency in accounting, "the language of business." After examining challenges faced by nurse executives, faculty at the Loewenberg School of Nursing at the University of Memphis integrated intensive accounting education into a new executive MSN program. Woven throughout the management accounting course is the concept that accounting data must be relevant and accurate for use by organization decision makers. Evidence-based decision making is emphasized when teaching planning and control activities. In addition, fluency in accounting is enhanced which leads to greater skill in patient and nursing advocacy. As competency in management accounting increases through the semester, executive MSN students are encouraged to apply cost accounting course content to their practice settings and to analyze how planning or control activities improve quality outcomes.     

THE ROLE OF RETIREE HEALTH INSURANCE IN THE EMPLOYMENT BEHAVIOR OF OLDER MEN*

Using data from the Health and Retirement Survey, we estimate preference and expectations parameters of a structural model of the employment and medical care decisions of older men in order to evaluate the role of health insurance. The budget constraint incorporates detailed cost‐sharing characteristics of private health insurance and Medicare as well as rules and requirements associated with Social Security and private pensions. Simulations imply that changes in health insurance, including access and restrictions to retiree health insurance and Medicare, have a modest impact on employment behavior among older males, with the greatest effect on men in bad health.     

Bias against overweight job applicants: Further explorations of when and why

We investigated the impact of job candidate weight (average or overweight) on several job‐related ratings following a videotaped mock interview. In ad‐dition to weight, we manipulated the race of the applicant, level of job qual‐ifications, and type of job (e.g., public or private contact). We also measured the effect of rater race and negative affect on multiple work‐relevant ratings. Weight, applicant race, job qualifications, and job type each had a modest but significant impact on ratings of hireability, performance capacity, adapt‐ability, and interpersonal skills, in varying combinations. The implications of these results for practice and future research are provided. © 2007 Wiley Pe‐riodicals, Inc.     

Distributed group support: The effects of voting Tools on group perceptions of media richness

Decision groups distributed both temporally and geographically encounter a multitude of coordination problems. This experiment used a set of GDSS Tools called List and Vote, and alternative interaction management procedures, as mechanisms for coordinating distributed groups using a computer conferencing system and for structuring group processes. The study examined media richness using a modification of the adjective-pairs developed by Zmud, Lind, and Young (1990). The Tools significantly improved subjective perceptions of media richness. The attempted manipulation of the presence or absence of sequential procedures for the most part was not effective in creating significant differences in group perception of media richness.
