Hip protectors in the elderly: lack of effectiveness or just suboptimal implementation?

Hip protectors seemed to be the only non-pharmacological intervention to effectively prevent hip fractures in high-risk populations. In contrast, recently published trials did not find hip fracture reduction through hip protector interventions. An updated Cochrane review concluded that the device is ineffective for community-dwelling elderly and of uncertain effectiveness for institutionalised elderly. However, some primary studies used suboptimal implementation of hip protectors, which has led to low adherence and ineffectiveness of the intervention. Shortcomings in implementation techniques have not been assessed by the Cochrane review. Therefore, reviewers should explicitly assess whether the intervention was well planned and competently administered. As a checklist cannot adequately assess individual, study-specific implementation flaws, we suggest narrative expert review and feedback to the authors of the primary study.     

Supporting Asian Deaf Young People and their Families: the role of professionals and services

This paper discusses how Asian deaf young people and their families engage with welfare provision. Our findings, based on group and individual interviews with young deaf people and individual interviews with their parents, explore the assumptions underlying current provision and how they influence the options available to young people and their families. The paper suggests that the welfare state exerts a form of social control where professional help, although well intended, may disempowers Asian deaf people by privileging 'oralism' over sign language, and western norms over other cultural values. On the other hand, positive constructions of deafness privilege Deaf identity while failing to accommodate ethnic or religious diversity, resulting in Asian deaf young people and their families having an ambivalent relationship with the Deaf community. We argue that services need to recognise and address the reasons for this ambivalence if they are to adequately engage Asian deaf people and their families.     

Seasonal patterns of fertility measures: A Bayesian approach

Becker (1981) presents some theory about related measures of fertility. He SUMMARY compares his theoretical predictions with observed relationships found in a set of data collected in Bangladesh. In general, he finds good agreement. In this paper, we reanalyse the data using Bayesian methods. In particular, we use Gibbs sampling to fit trigonometric regression models with autocorrelated errors. The results are generally in agreement with Becker's. However, evidence from one of the autocorrelation parameters and a residual analysis casts some doubt on whether the basic cosine model which is assumed fits the data well.     

Pathways to Intergenerational Adolescent Childbearing in a High‐Risk Sample

Previous research indicates that children of adolescent mothers are more likely to experience an adolescent birth than are children of older mothers. Using a longitudinal sample of 293 high‐risk mothers and their 19‐year‐old children, we investigated mediators of the intergenerational pattern of adolescent childbearing. Results from multigroup path models indicate that the intergenerational effect is (a) significant for children of unmarried mothers above and beyond mother’s prebirth socioeconomic status and education level, (b) fully mediated through early sexual intercourse related to presence of a father figure and early home environment for girls, and (c) partially mediated by early physical development for boys. Relation of findings to current models of early sexual behavior and childbearing is discussed.     

Assessing Poisson variation of intestinal tumour multiplicity in mice carrying a Robertsonian translocation

Summary.  Tumour multiplicity is a frequently measured phenotype in animal studies of cancer biology. Poisson variation of this measurement represents a biological and statistical reference point that is usually violated, even in highly controlled experiments, owing to sources of variation in the stochastic process of tumour formation. A recent experiment on murine intestinal tumours presented conditions which seem to generate Poisson-distributed tumour counts. If valid, this would support a claim about mechanisms by which the adenomatous polyposis coli gene is inactivated during tumour initiation. In considering hypothesis testing strategies, model choice and Bayesian approaches, we quantify the positive evidence favouring Poisson variation in this experiment. Statistical techniques used include likelihood ratio testing, the Bayes and Akaike information criteria, negative binomial modelling, reversible jump Markov chain Monte Carlo methods and posterior predictive checking. The posterior approximation that is based on the Bayes information criterion is found to be quite accurate in this small n case-study.     

Gender Convergence in the American Heritage Time use Study (AHTUS)

The present study explored the short-term temporal characteristics of subjective well-being (SWB) and its potential correlates. Specifically, we examined the intra-individual variability and the trajectories of SWB and its components life satisfaction, positive, and negative affect. Over a two-week period, 27 participants (78% university students, 85% females, mean age of 29 years) provided SWB data every other day. Before and after this period, participants completed several questionnaires assessing personality and environmental variables, as well as several open-ended questions. The results provide evidence that participants experienced a significant amount of intra-individual variability in their SWB and its components. Furthermore, inter-individual differences in the intra-individual variability were related to several of the personality and environmental variables, as well as to participant’s age. Results of multiple regression analyses indicated that deliberation (one facet of the Big Five dimension conscientiousness), social support, and age accounted for 58% of the total variance of intra-individual variability in SWB. In contrast, the slopes of the individual trajectories of SWB were on average statistically non-significantly different from zero. These results emphasize that information is gained by looking at both the patterns and the intra-individual variability over time: The individual trajectories of the participants on average appeared to be stable, but intra-individual variability of SWB was meaningfully related to several of the variables.     

Medical Family Therapists in Action: Embracing Multiple Roles

Medical family therapy (MedFT) is a growing area of interest within the field of marriage and family therapy. Its practice necessitates a shift from conventional family therapy practices to include diverse ways of providing care. Literature highlights approaches for patients with specific illnesses and for particular healthcare contexts. Less is understood about frameworks for treating patients with different illnesses across settings. Contributing to the growing discourse surrounding MedFT, we present a role‐based practice framework that identifies six consistent roles, Therapist, Brief Interventionist, Health Coach, Patient Advocate, Consultant to Health Professionals, and Trainer specific tasks associated with each. We describe the skills needed to perform each role and describe how we move fluidly between roles to provide comprehensive care.     

Fitting in: Group effects and the evolution of fundamentalism

We provide an evolutionary model of conflict based on dyadic interactions within and between individuals drawn from a society containing fundamentalists and “others.” Thus, the paper presents an asymmetric game representation of group effects. Fundamentalist control of society is inversely related to the degree of social stratification, and fundamentalists’ intolerance of others. If, however, fundamentalism can be feigned (by displaying certain traits), then fundamentalists must balance their intolerance and insularity to take power. The model provides a novel means for distinguishing democratic versus open societies. This leads to a central result characterizing how fair and open societies can peacefully contravene fundamentalism.
