Sensitivity, Specificity and Predictive Capacity of the Bayley-III in Full Term Children

This item is only available electronically.This paper reviews the existing literature on the predictive capacity of the Bayley Scales of Infant Development, 3rd edition (Bayley-III). A number of areas of concern have been identified including the tendency of the Bayley-III to overestimate ability, thereby underestimating delay. Research pertaining to the predictive capacity of the Bayley-III is reviewed in the context of the sensitivity and specificity, relating to delay. Difficulties in the assessment of development are explored and discrepancies between test scores on the Bayley-III and other measures are addressed in this context. Limitations of the current body of research, such as its focus on preterm populations, are presented and recommendations for further research are discussed.Thesis (M.Psych(Clinical)) -- University of Adelaide, School of Psychology, 201

The Effect of an In-season Weight Training Program on the Muscular Strength of Intercollegiate Football Players

Intercollegiate football has become highly competitive over the past decade. As new records are set each year, offensively as well as defensively, it is imperative that players maintain a high level of strength throughout the competitive season. Ample investigations have been conducted in off-season weight training; however, there are few investigations pertaining to the use of a weight training program during the competitive season. McKay believes that while a weight training program must develop strength and endurance in the muscles used in playing the game, the program must not reduce the players’ reflexes or speed. At one time, in-season weight training was regarded as an inappropriate practice. Capen stated that exercise with weights would produce “muscle tightness.” Chic also observed that many coaches have associated weight training with “muscle boundness,” but he could find no scientific evidence to support this theory. Interest in the use of an in-season weight training program at the college level in growing; however, information related to the specific effects f this type of training in extremely limited. At least one writer, Juvenal, has suggested that with no attention given to strength training during a football season, players will experience a decrement in strength as the season progresses. Guyton supported this view when he noted that muscles not used for one to two months can decrease to one-half their normal size. With this decrease in girth, there is a proportionate reduction in muscular strength. But supporting data are scarece and in view of this paucity of data, the present researcher conducted an investigation to determine whether an in-season weight training program might influence the strength of intercollegiate football players as the competitive season progressed. The purpose of this study was to determine the effect of an in-season weight training program in selected measures of strength of intercollegiate football players during the competitive season

New Approaches Needed for Water Quality Gains in the 1990s

In the land of 15,000 lakes, 91,944 river miles and a trillion gallons of ground water, the summer of 1988 saw the unlikely come to pass. The mighty Mississippi dropped to less than one-tenth of its normal flow. Crops withered, grass turned brown, and well pumps burned out in the most hellish heat wave since the 1930s. While the drought was primarily an issue of insufficient water quantity, it also served to focus additional attention on water quality. Water quality concerns are not new to Minnesota, which has led the nation in protecting the environment for two decades. Nonetheless, the drought has prompted us to take stock of how far we have come in protecting our waters, and where we need to go from here

Common variations in ALG9 are not associated with bipolar I disorder: A family-based study

Background: A mannosyltransferase gene (ALG9, DIBD I) at chromosome band 11q23 was previously identified to be disrupted by a balanced chromosomal translocation t(9; 11)(p24;q23) co-segregating with bipolar affective disorder in a small family. Inborn ALG9 deficiency (congenital disorders of glycosylation type IL) is associated with progressive microcephaly, seizures, developmental delay, and hepatomegaly. It is unknown whether common variations of ALG9 predispose to bipolar affective disorder. Methods: We tested five polymorphic markers spanning ALG9 (three intragenic and one upstream microsatellite repeats and one common missense variation, V2891 (rs10502151) for their association with bipolar I disorder in two pedigree series. The NIMH (National Institute of Mental Health) pedigrees had a total of 166 families showing transmissions to 250 affected offspring, whereas The PITT (The University of Pittsburgh) pedigrees had a total of 129 families showing transmissions to 135 cases. We used transmission disequilibrium test for the association analyses. Results: We identified three common and distinct haplotypes spanning the ALG9 gene. We found no statistically-significant evidence of transmission disequilibrium of marker alleles or multi-marker haplotypes to the affected offspring with bipolar I disorder. Conclusion: These results suggest that common variations in ALG9 do not play a major role in predisposition to bipolar affective disorder. © 2006 Baysal et al; licensee BioMed Central Ltd
