Behavioral control of exercise in adults: Studies 7 and 8

Abstract

Building on our previous six study series, the current studies 7 and 8 evaluated behavioral methods of improving adherence to exercise in adults. The studies tested the effectiveness of a single exercise modality versus choice of a variety of exercises and were conducted as part of a 12-week extended studies college course in San Diego, CA. Recruitment efforts were targeted to individuals who reported that they were sedentary and/or had experienced difficulty adhering to regular exercise. Participants were 42 adults (32F, 10M; mean age = 42.0) in Study 7 and 48 adults (35F, 8M; mean age = 47.9) in Study 8. In each study, subjects were randomly assigned to a single focus or variety exercise condition. There were no significant group differences in class attendance or out-of-class exercise adherence rates in Studies 7 or 8. In Study 7, significantly lower drop-out rates were detected in the single focus group (19%) than the variety condition (47.6%) (p = 0.04). No significant group differences were detected for drop-out rates in Study 8. Suggestions for further research are offered.     

Thoughts Associated with Unprotected Anal Intercourse Among Men at High Risk in San Francisco 1997-1999

Men who had high-risk sex with men in the previous year ( N = 124) were asked to recall their thought processes at the time they last had unprotected anal sex with a man who was HIV-positive or of unknown serostatus. Self-justifications for non-condom use were examined individually and in internally validated scales. The most common single self-justification was I want to have unprotected sex because it feels good , endorsed by 76%. Other common thoughts included the notion that it is only human to slip up occasionally (59%) and the resolution to withdraw before ejaculation (59%). For scaled items, the most strongly endorsed themes were: (1) that condoms reduce sexual pleasure (any of 6 items endorsed at least slightly by 90%); (2) fatalism or leaving it to chance (11 items, 81%); and (3) loss of control (9 items, 77%). The thoughts and themes identified may be useful in planning individual and community prevention messages.     

Trying in some way

Most discussions about trying assume that the expression ‘person P's trying to ?’ refers to a particular of some sort. These discussions then differ amongst themselves about to which metaphysical type these particulars belong: mental particulars, brain states, or physical actions are three of the most obvious candidates. This paper examines that assumption and in particular considers an argument of Davidsonian inspiration that might be used in its favour, which is based on the fact that the verb ‘try’ appears to take adverbial modification. Reasons are offered for rejecting this Davidsonian line of argument. A further argument for rejecting the assumption that ‘P's trying to ?’ is a genuinely referring expression is modelled on Jonathan Bennett's discussion of event names.     

A case of subcortical dementia due to sarcoidosis of the hypothalamus and fornices

A patient with sarcoidosis involving predominantly the hypothalamus and fornices was evaluated for dementia. He showed a relative sparing of fund of knowledge and orientation. Memory skills, particularly short-term memory, were severely impaired. Behavioral changes included apathy and a lack of spontaneity. Insight was relatively preserved. The pattern of his deficits showed some similarities to the pattern reported in patients with Huntington's disease and was different from that described in Alzheimer's disease. The dementia caused by subcortical pathology may differ in important respects from that caused by diffuse cortical dysfunction.     

BIOMEDICAL ETHICS: MUSLIM PERSPECTIVES ON GENETIC MODIFICATION

Technology pertaining to genetically modified foods has created an abundance of food and various methods to protect new products and enhance productivity. However, many scientists, economists, and humanitarians have been critical of the application of these discoveries. They are apprehensive about a profit‐driven mentality that, to them, seems to propel the innovators rather than a poverty‐elimination mentality that should be behind such innovations. The objectives should be to afford the most benefit to those in need and to prevent hunger around the world. Another major concern is the safety of genetically modified food. Muslims, as well as those in other religious communities, have been reactive rather than proactive. Muslims must connect scientific knowledge and ethical behavior based on faith. In Islam, there is no divide between the two. God has commanded us to seek knowledge and make discoveries to better our lives and our environment. We are trustees of this world and everything in it. The poor, the sick, and the wayfarers have a right to be fed and cared for. God reminds Muslims continuously that the earth and all the heavens belong to God; therefore, no one should feel hunger, no one should suffer or be prevented from sharing this bounty.     

Women in male-dominated professions: Contrasts in their personal and vocational histories

Women in four high-status, male-dominated professions—architecture, law, medicine, and psychology—are described in terms of a variety of historical, social, and career variables. The women share common antecedents of their vocational choices and similar perceptions of their work, but the occupational groups are dissimilar on a number of dimensions. Psychologists stand in particular contrast to the other three groups of professionals, describing experiences and career patterns less in conflict with stereotypic female roles. These contrasts may reflect differences in the sex-typed characterizations of the professions even though all are male-dominated.     

THE IMPACT OF APPLIED BEHAVIOR ANALYSIS ON DIVERSE AREAS OF RESEARCH1

The impact of applied behavior analysis on various disciplines and areas of research was assessed through two major analyses. First, the relationship of applied behavior analysis to the general area of “behavior modification” was evaluated by examining the citation characteristics of journal articles in JABA and three other behavior-modification journals. Second, the penetration of applied behavior analysis into diverse areas and disciplines, including behavior modification, psychiatry, clinical psychology, education, special education, retardation, speech and hearing, counselling, and law enforcement and correction was assessed. Twenty-five journals representing diverse research areas were evaluated from 1968 to 1974 to assess the extent to which operant techniques were applied for therapeutic, rehabilitative, and educative purposes and the degree to which methodological desiderata of applied behavior analysis were met. The analyses revealed diverse publication outlets for applied behavior analysis in various disciplines.
