Academic economists behaving badly? A survey on three areas of unethical behavior

This article measures the degree to which academic economists have engaged in unethical behavior and the degree to which academic economists believe the profession as a whole engages in unethical behavior. Three main types of unethical behavior are examined: (1) falsification of research; (2) expropriation of graduate student research or including an undeserving co-author on a research paper; and (3) exchange of grades for gifts, money, or sex. Using a unique data set gathered at the 1998 American Economic Association (AEA) meetings, we find that there is a significant amount of misconduct, particularly in the second category.     

Developing expert systems for management applications

The Alvey Report has resulted in a growing interest in the UK in ‘expert systems’. It is fairly generally accepted, at least in the UK, that such systems function in a particular type of way, i.e. they arrive at decisions through a process of rule based inference. It is suggested that it may be more fruitful to regard rule based inference as one approach to the construction of expert systems, and that proven techniques of operational research may well be more useful in constructing other types of expert system. Alternative applications of expert systems are derived on the basis of a broader definition of an expert system in terms of what it does rather than how it does it. A parallel is drawn between these applications and some typical concerns of business research. It is suggested that a useful aid in identifying promising business applications of expert systems is to set up four ‘dimensions’ along which different types of system differ. Examples are given of where other techniques might conceivably be useful in applications of expert systems.     

Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands

Elissen AMJ, Van Raak AJA, Derckx EWCC, Vrijhoef HJM. Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands Faced with rising homelessness, countries around the world are in need of innovative approaches to caring for those without shelter, who, more often than not, suffer from severe health problems. We conducted a case study of an innovative Dutch Primary Care for the Homeless (PCH) programme to gain insight into clients' demographic characteristics, health problems and service use, and to develop an explanation for its success in increasing the latter. Our analyses are based on a combination of quantitative and qualitative data. The results of the study suggest that the success of the PCH programme can be explained by the providers' pragmatism and will to adapt their mode of care provision to the behavioural patterns and needs of their homeless clients.     

The Quintessential Rural Sociologist*

Alvin L. Bertrand's career and research have made him an exemplar of humane social scientist, scholar, and academician. For many of his peers, Bertrand is the quintessential rural sociologist. Spending almost all of his career at Louisiana State University, Dr. Bertrand has addressed an extraordinarily broad array of social phenomena, often of a community problem variety, in his research. His research employed a social systems analysis frequently focused on the rural context and had a strong applied orientation with the result that his findings have been widely used as the basis for the formulation of important national and international program and policy decisions. Bertrand's work has attracted wide attention abroad as well as in the United States. Because of his many contributions to the discipline of sociology, he has received numerous awards and recognitions and has also been elected to various offices in professional societies and associations, including the presidency of five such groups.     

Parental underinvestment: A link in the fertility-mortality continuum

Selective parental investment in siblings has been used to describe differential mortality rates. Using data from 986 Filipino women who had an average of 4.8 live births, a LISREL and six sets of regression models support the hypothesis that fertility is linked to underinvestment and that mortality, as a consequence, is linked to high birth order. The analysis also identifies intervening factors associated with this relationship. Age of mother at childbirth showed a strong influence on the relationship of birth order and infant and child mortality; correlations are stronger among older than youger mothers. However, even after the effect of age of mother at childbirth was partialled out, the effect of birth order on infant and child mortality remained significant and substantial. The conclusion is that parental underinvestment represents a link between fertility and mortality during infancy and early childhood that has not been described previously. Policy makers appear to have overlooked parental underinvestment in favor of more obvious economic and health mediators.     

The simulation of industrial robot systems

This paper describes the GRASP computer aided design system for modelling and evaluating industrial robot workplaces. GRASP satisfies a range of simulation needs within the context of designing, implementing and operating industrial robotic systems. The GRASP software may be used to investigate robots operating by themselves or, more likely, as part of an integrated cell. Facilities within GRASP assist workplace layout, position and velocity evaluations, clash detection and co-ordination between items. A robot library exists and is being extended, and an embryo off-line programming facility has been used under restricted conditions. GRASP has been used to help solve a wide range of practical industrial robot problems and has proved itself technically, and also as an educational tool, by showing how a proposed system would operate. The paper describes the facilities within GRASP.     

Unsanctioned births in China

This study hypothesizes that "unsanctioned" births (beyond the limit authorized by the government) in China are more likely among couples who have strong traditional fertility norms and less likely among couples who adopt new family planning norms. The theoretical framework is based on cultural conflict theory as developed by Sellin. Data are obtained from 6654 ever married women aged under 49 years from the 1987 In-Depth Fertility Survey for Guangdong province. Over 30% of the sample were married before 20 years of age. 20% had 1 child, 26.7% had 2 children, about 23% had 3 children, 13.9% had 4 children, and under 10% had 5 or more children. The average number of living children was 2.5. Findings reveal that socioeconomic status was significantly related to unsanctioned births; they were more common in less developed areas and among women of lower socioeconomic status (SES). Persons living in areas with a high monetary contribution per person in family planning efforts at the county level were less likely to have unsanctioned births. Women who lived in urban areas, worked in state enterprises, and had parents with high educational status were less likely to have unsanctioned births. They were more likely among women who married at an early age, lived with parents after the marriage, had female living children, and had failed pregnancies. They were also more likely among women who had arranged marriages, a traditional desire for large family sizes, an early marriage ideal, and a preference for sons. Knowledge of family planning and greater use of abortion were related to a lower incidence of unsanctioned births. Women who talked with their husbands about their family size desires were less likely to have unsanctioned births. Parental educational attainment only had an influence among rural women. Variables impacted on fertility differently in urban and rural areas.     

Demographic and sociological determinants of alcohol use by U.S. military personnel

Using a worldwide sample of U.S. military personnel, this study examines the demographic characteristics and the drink‐related determinants of alcohol use. Scales are developed to describe four use predictors: personal benefit, problem situation, peer influence, and normative definition. Findings using multiple regression and path analysis indicate that personal benefit is the most important determinant in predicting alcohol use. The effects of problem situations on alcohol use are largely mediated by personal benefit. Moreover, peer influence not only directly influences alcohol use, but also mediates the effect of age on alcohol use. Inconsistent with previous research with civilian populations, normative definitions of alcohol use were not found to be a good predictor of alcohol use.
