A work role perspective of accountants in local government service departments

In most of the largest U.K. local authorities the financial control function is highly centralised with no qualified accountant or controller located in each spending department. There now may be the beginnings of a trend towards employing accountants within service departments. The paper analyses how this new segment of public sector accounting appears to be becoming established, how the role of these accountants is being developed and the contrasting occupational values of accountants in service departments and those in the finance department. It is also shown how the existence of a strong accounting profession in local government can lead to different aspects of both the financial control structure and process in comparison with central government such that research results on the latter may not automatically hold at local level.     

Business and national priorities for industrial development: Intersectoral consensus in Israel

This study describes a survey of experts chosen from Industry, Labour, and Government in Israel, who ranked and scored three business and four national goals in the context of industrial development. The business goals represented profitability, capital use and growth potential. The national goals involved human resource utilization, added value, foreign exchange conservation, and export of technologically advanced products. The findings support a hypothesis of consensus on goals and goal priorities between different sectors of the Israel economy, despite what might appear to be their divergent special interests. The findings also indicate overall consensus with respect to a balance between business and national goals. The study concludes that this consensus is the result of the need to respond to environmental threats and uncertainties which has created a sense of mutual interdependence among the sectors.

Summary of Results of Survey of Seminar Attendees

Abstract

The Society of Actuaries undertook a three-phase research project on mortality improvement in the three NAFTA countries: Canada, Mexico, and the U.S. Phase 1 consisted of a literature review of papers on projecting mortality levels in the future and a study of the trend in mortality improvement during this century. Phase 2 consisted of a discussion of different facets of modeling mortality rates at a seminar attended by 79 experts (actuaries, demographers, economists, and medical researchers) representing different countries. The last session of the seminar consisted of the completion of a survey by the attendees to obtain input for Phase 3, which would analyze the impact of mortality improvement on the social security system of each country. This paper summarizes the results of the survey.

The survey results illustrate the difficulty in forecasting mortality levels, because the effects of many factors that could have significant impact on mortality rates are unknown. This suggests the need for dynamic forecasting, which allows for the possibility of random shocks. A majority of the survey respondents believe that stochastic forecasting models, despite their complexity, have significant potential to add value. Respondents also believe that both historical data and cause-specific mortality forecasts are useful as input and also in validating forecasts of the aggregate levels of mortality. The challenge is to develop more sophisticated forecasting models to produce results that are relatively easy to interpret and to communicate these results to the desired audiences, including the public and policymakers.

The survey results suggest that the aggregate effect of lifestyle changes, medical advances, diseases, catastrophe, and physical environmental changes is an increase in life span. However, there is much uncertainty about the future. Respondents expect that beyond the year 2020 the mean annual rate of reduction in mortality for males age 65 and over will average about 0.58% for Canada, 0.76% for Mexico, and 0.67% for the U.S. The results for the female age 65 and over population are 0.64%, 0.83%, and 0.70%, respectively. The age 65 and over population is expected to see larger percentage reductions in mortality than the 0–14 and 15–64 populations. The reductions in male and female mortality will be ultimately the same, and the mortality levels in the three countries will ultimately converge, although differences may persist for decades.     

A note on the evaluation of information in zero-sum repeated games

Two players play a zero-sum repeated game with incomplete information. Before the game starts one player receives a private signal that depends on the realized state of nature. The rules that govern the choice of the signal are determined by the information structure of the game. Different information structures induce different values. The value-of-information function of a game associates every information structure with the value it induces. We characterize those functions that are value-of-information functions for some zero-sum repeated game with incomplete information.     

Enumeration of Nash equilibria for two-player games

This paper describes algorithms for finding all Nash equilibria of a two-player game in strategic form. We present two algorithms that extend earlier work. Our presentation is self-contained, and explains the two methods in a unified framework using faces of best-response polyhedra. The first method lrsnash is based on the known vertex enumeration program lrs, for “lexicographic reverse search”. It enumerates the vertices of only one best-response polytope, and the vertices of the complementary faces that correspond to these vertices (if they are not empty) in the other polytope. The second method is a modification of the known EEE algorithm, for “enumeration of extreme equilibria”. We also describe a second, as yet not implemented, variant that is space efficient. We discuss details of implementations of lrsnash and EEE, and report on computational experiments that compare the two algorithms, which show that both have their strengths and weaknesses.     

Intervening with victims of intimate partner violence

Intimate partner violence (IPV) is a critically important public health problem. Physicians and other health care providers have a unique opportunity to help IPV victims, not only in treatment but in prevention of this devastating problem. Health-care providers should receive thorough and on-going training and administrative support for identifying, appropriately treating, and referring IPV victims to IPV advocates and other community-based resources with whom the provider has developed a close working relationship. In the clinical setting, health-care providers may intervene early as the victim’s first and only point of contact concerning the violence in their lives. In the larger community, health-care providers can become spokespersons and educators to help change social norms and can get involved in coordinated community responses to ensure cohesive actions by all societal sectors to prevent IPV in their communities.
