The Mathematics Anxiety Rating Scale (MARS) (F. Richardson and R. Suinn, 1972) was submitted to a reliability generalization analysis to characterize the variability of measurement error in MARS scores across administrations and to identify possible study characteristics that are predictive of reliability variation. The meta-analysis was performed with 67 studies that met study criteria. In gen...

Between 40% and 80% of the variation in human intelligence (IQ) is attributable to genetic factors. Except for many rare mutations resulting in severe cognitive dysfunction, attempts to identify these factors have not been successful. We report a genomewide linkage scan involving 634 sibling pairs designed to identify chromosomal regions that explain variation in IQ. Model-free multipoint linka...

BACKGROUND Geographical variation in the prevalence of common mental disorders has not been explained adequately. AIMS To investigate whether regional mental health differences in Wales would persist after having taken into account the characteristics of individuals and regional social deprivation. METHOD Data from the 1998 Welsh Health Survey were used. Common mental disorders were assesse...

Records of 547, 2-yr-old heifers of three breed groups were used to evaluate the relative influence of dam's body and pelvic measurements, calf birth weight, sire birth weight and some relative measures (ratios) of calf birth weight and dam weight at calving on calving difficulty. The data were analyzed by regression and least squares procedures. The full model explained 32.5% of the variation ...

BACKGROUND Self-management education (SME) is an important yet unacknowledged aspect of diabetes care. Despite the raise of diabetes and its complications with significant burden in developing countries, research on SME interventions in Morocco is lacking. AIMS To assess the effectiveness of a culturally tailored SME intervention on foot-care self-management practices among type 2 diabetes pa...

BACKGROUND The response to dietary fat plays a key role in metabolic health. Although this can vary widely between individuals, variation within an individual and the associated contribution of phenotypic and genotypic factors to this variation are less defined. OBJECTIVES The objectives were to quantify within-person variation in triacylglycerol response by means of a novel variation score (...

BACKGROUND Unintentional injury is the leading cause of death in children older than 1 year. Deaths from accidents have a steeper class gradient than any other fatal condition and this inequality is widening. There are few published data on the relationship between safety practices and sociodemographic characteristics, hence this study has been undertaken to examine this relationship. METHODS...

BACKGROUND Circadian clocks guide the metabolic, cell-division, sleep-wake, circadian and seasonal cycles. Abnormalities in these clocks may be a health hazard. Circadian clock gene polymorphisms have been linked to sleep, mood and metabolic disorders. Our study aimed to examine polymorphisms in four key circadian clock genes in relation to seasonal variation, reproduction and well-being in a s...

OBJECTIVES To assess the effects of bariatric surgery in patients with obesity on dyspnea and to analyze the relationships between improvement of dyspnea after bariatric surgery and changes in pulmonary function, especially Expiratory Reserve Volume (ERV) which is the lung volume abnormality most frequently associated with obesity. METHODS Forty-five patients (5 males/40 females, mean Body Ma...

BACKGROUND Synonymous mutation is the single nucleotide change that does not cause an amino acid change but can affect the rate and efficiency of translation. So recent increase in our knowledge has revealed a substantial contribution of synonymous mutations to human disease risk and other complex traits. Nevertheless, there are still rarely synonymous mutation prediction methods. METHODS Non...
