The No Probabilities For Acts-Principle

One can interpret the No Probabilities for Acts-Principle, namely that any adequate quantitative decision model must in no way contain subjective probabilities for actions in two ways: it can either refer to actions that are performable now and extend into the future or it can refer to actions that are not performable now, but will be in the future. In this paper, I will show that the former is the better interpretation of the principle.     

Early development of delinquency within divorced families: evaluating a randomized preventive intervention trial

This paper reports on an experimental test of coercion theory early onset model of delinquency. Results are from the Oregon Divorce Study-II, a randomized preventive intervention trial with a sample of 238 recently separated mothers and their sons in early elementary school. The objective was to experimentally manipulate parenting variables hypothesized to influence development of delinquent behaviors. Multiple-method assessment spanned 36 months. Because the intervention focused on parent training, we expected that any intervention effects on changes in child outcomes would be mediated by hypothesized intervening mechanisms. Linear growth models showed significantly greater reduction in boys' delinquency and deviant peer affiliation in the experimental group relative to the controls. Subsequent models using no method overlap in constructs demonstrated that the intervention effect on delinquency operated through growth in parenting and reduction in deviant peer affiliation.     

'Questions, questions, questions!' A comparison of therapist inferences and parental responses to systemic questions

Using a specially designed questionnaire, we examined the relationship between parental responses to systemic questions, therapists'views based upon these responses and parental reports of dysfunction in a member of the family. The questionnaire was completed by parents of a randomly selected population sample of adolescents and by experienced family therapists. Therapists made inferences that were predictable, coherent and reliable. They gave most salience to the concept of'enmeshment'and least to'hostile-discordant'functioning. Some enmeshed answers were favoured by substantial proportions of parents, suggesting that they may reflect normal variants of family functioning. However no associations between total enmeshment scores and reported mental health problems were found. Hostile-discordant functioning, as assessed in this study, was rare in the general population sample, but was associated with reported problems.     

Operant conditioning of goats

A procedure is described for establishing an operant response in goats. The operanda are two lucite panels which can be transilluminated. The goats press the panels with their muzzles and are reinforced with whole oats. All six subjects showed reliable and accurate performance in brightness discrimination, including cessation of responding during time-out periods.     

Age-associated predictors of medication adherence in HIV-positive adults: health beliefs, self-efficacy, and neurocognitive status.

OBJECTIVE: Although most agree that poor adherence to antiretrovirals is a common problem, relatively few factors have been shown to consistently predict treatment failure. In this study, a theoretical framework encompassing demographic characteristics, health beliefs/attitudes, treatment self-efficacy, and neurocognitive status was examined in relationship to highly active antiretroviral therapy adherence. DESIGN: Prospective, cross-sectional observational design. MAIN OUTCOME MEASURES: Neuropsychological test performance, health beliefs and attitudes, and medication adherence tracked over a 1-month period using electronic monitoring technology (Medication Event Monitoring System caps). RESULTS: The rate of poor adherence was twice as high among younger participants than with older participants (68% and 33%, respectively). Results of binary logistic regression revealed that low self-efficacy and lack of perceived treatment utility predicted poor adherence among younger individuals, whereas decreased levels of neurocognitive functioning remained the sole predictor of poor adherence among older participants. CONCLUSION: These data support components of the health beliefs model in predicting medication adherence among younger HIV-positive individuals. However, risk of adherence failure in those ages 50 years and older appears most related to neurocognitive status.     

Flood of emotions: emotional work and long-term disaster recovery

This paper uses concepts of emotion work and emotional labour to explore people’s experiences of the long-term disaster recovery process. It draws on data taken from two qualitative research projects which looked at adults’ and children’s recovery from the floods of June 2007 in Hull, UK. The paper argues that the emotional work of recovery cannot be separated from the physical and practical work of recovering the built environment. It shows that a focus on emotion work can lead to a more nuanced understanding of what recovery actually means and who is involved, leading to the identification of hidden vulnerabilities and a better understanding of the longer timescales involved in the process.
