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.     

Understanding the demographic characteristics of urban men who have sex with men

We examined migration, closetedness, and family structure explanations of demographic profiles of urban men who have sex with men (MSM) using data from the Urban Men's Health Study and the Public Use Microdata Sample of the U.S. Census. The data suggested that the demographic profiles of urban MSM reflect a large in-migrating white, often young adult, population without children. Closetedness, an oft-cited bias in MSM population studies, did not significantly impact demographic patterns with minor exceptions. MSM urban subpopulations have demographics that differ substantially from the general population of the cities in which they reside.     

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 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.     

Recalling sexual behavior: A methodological analysis of memory recall bias via interview using the diary as the gold standard

This study examined the effect of time lag on the validity of retrospective self‐reports of sexual behavior. Seventy‐five heterosexual students (44 women, 31 men) made daily recordings of sexual behavior, condom use, and alcohol or substance use for 1 month. Ability of respondents to recall sexual behavior recorded during this period was assessed at 1, 2, and 3 months after diary completion using recall interviews (25 interviewed at each interval). For vaginal intercourse, total recall error was significantly greater at 3 months than at 1 month post‐diary. For all other variables assessed, the 2‐ and 3‐month time intervals did not produce significant increases in total recall error. Higher frequency of vaginal intercourse, orgasm, and alcohol use prior to sexual activity were associated with total recall error for some but not all behaviors and outcomes. The results provide a partial validation of the diary‐interview recall model as a method for studying recall error.
