Ultrasonometric profiling of incidence and risk of osteoporosis in rural women

BACKGROUND: It is estimated that over 200 million people worldwide have osteoporosis. The prevalence of osteoporosis is continuing to escalate with the increasingly aging population. The major complication of osteoporosis is an increase in fragility fractures leading to morbidity, mortality, and decreased quality of life. This investigation profiled the incidence and risk of osteoporosis in adult women from a rural setting using ultrasonic bone scanning technology. METHODS: Between 2001 and 2005, adult female subjects (n = 323) in the age range of 40-87 were drawn from an independent, community dwelling, convenience sample. Bone mineral density T-scores were evaluated using heel ultrasonometry. Demographic and risk factor data, Merck Osteoporosis Evaluation SCORE questionnaire data, and the Osteoporosis Risk Assessment questionnaire data were analyzed. RESULTS: Results of these scans indicate that 25% of the total population had a T-score < or = -1.0, implying a 1.5- to 2.0-fold increase in risk ratio of hip or spinal fracture for each standard deviational decrease. Age at menopause and weight had a positive correlation with T-scores. While the overall scores on the Merck SCORE questionnaire were inversely correlated to T-scores, no significant correlation was found between the Osteoporosis Risk Assessment questionnaire and T-score data. Additionally, women who had taken estrogen had significantly higher T-scores (p = 0.038) than those who had not. CONCLUSION: That approximately 25% of this sample has low bone mass or osteoporosis underscores the importance of early screening in order to develop preventative awareness and provide education on bone health management. This finding has particularly important ramifications, since the sample was rural women, who typically have limited access to diagnostic bone density procedures.     

Complex Couples: Multi‐Theoretical Couples Counselling with Traumatised Adults Who have a History of Child Sexual Abuse

One of the major ways child sexual abuse can have an impact on individuals is in their later ability to have and maintain fulfilling couple relationships. Survivors may experience avoidance behaviours that become problematic in their adult intimate relationships. If couple therapists fail to focus on these traumatic imprints, the therapy may founder. This paper proposes that a multi‐theoretical approach enables the couple therapist to deal with the complex problems such couples present including sexuality and intimacy concerns. Such an approach integrates trauma theory, attachment theory, feminist principles, body‐oriented psychotherapy, and systemic couple therapy.     

Setup Time Reduction for Electronics Assembly: Combining Simple (SMED) and IT‐Based Methods

As much as 50% of effective capacity can be lost to setups in printed circuit board assembly. Shigeo Shingo showed that radical reductions in setup times are possible in metal fabrication using an approach he called “Single Minute Exchange of Dies” (SMED). We applied SMED to setups of high speed circuit board assembly tools. Its key concepts were valid in this very different industry, but while SMED typically emphasizes process simplification, we had to add modern information technology tools including wireless terminals, barcodes, and a relational database. These tools shield operators from the inherent complexity of managing thousands of unique parts and feeders. The economic value of setup reduction is rarely calculated. We estimate a reduction of key setup times by more than 80%, and direct benefits of $1.8 million per year. Total cost of the changes was approximately $350,000.     

Nonverbal relational control in family communication

A nonverbal component for an observational coding system of verbal relational control, the Family Relational Communication Control Coding System (FRCCCS; Friedlander & Heatherington, 1989) was developed and validated for research with families or other groups. In so doing, it was demonstrated that nonverbal relational control behaviors can be reliably identified and that these behaviors enhance communicative meaning in predictable ways. First, a pool of nonverbal behaviors with relational control meaning (e.g., head nod, raised eyebrow) was identified from consultation with family therapy researchers and from the literature. Second, the behaviors that were retained from the results of a content validity test were perceived by three independent samples as commonly understood, discrete attempts to either gain control (one-up) or relinquish control (one down) of a social relationship. Still other behaviors were eliminated based on results of a cluster analysis, the interpretation of which was the basis for composing operational definitions for four classes of nonverbal behaviors. Finally, assessments of the interjudge reliability and criterion validity of the nonverbal coding scheme supported its psychometric adequacy. Comparison of effect sizes showed that these discrete nonverbal behaviors accounted for over twice the variance in observers' perceptions as the verbal behaviors.

Eliciting prior information to enhance the predictive performance of bayesian graphical models

Both knowledge-based systems and statistical models are typically concerned with making predictions about future observables. Here we focus on assessment of predictive performance and provide two techniques for improving the predictive performance of Bayesian graphical models. First, we present Bayesian model averaging, a technique for accounting for model uncertainty.

Second, we describe a technique for eliciting a prior distribution for competing models from domain experts. We explore the predictive performance of both techniques in the context of a urological diagnostic problem.
