Factors Influencing M.S.W. Students' Interest in Clinical Practice

This study utilizes linear and log‐linear stochastic models to examine the impact that a variety of variables (including graduate education) have on M.S.W. students' desires to work in clinical practice. Data was collected biannually (between 1992 and 1998) from a complete population sample of all students entering and exiting accredited graduate programs of social work in California (n = 5,793). The influences of past practice experiences, professional motivations, socio‐demographic characteristics, ideological affiliations, and education and training experiences while a graduate students were all examined. Findings suggest that there is tremendous commonality in the variability of interest toward doing clinical practice among all student groups both before and after the completion of graduate studies. Male and female students, students of varied ethnic, social class and political identifications/affiliations, along with students of varied ages did not differ in their desire or interest to engage in clinical practice. The desire to prepare for private practice had the strongest influence—that was maintained over the course of their education—on students' interests in clinical social work. Desires to work with the poor were not associated with students' desires to be clinicians who wish to apply their trade across a wide variety of problems and populations.     

Energy cost of different skating techniques in cross-country skiing

The aims of this study were to compare the aerobic energy cost of four 'on-snow' skating techniques in cross-country skiing and to examine the relationships between performance and aerobic energy cost. Twelve male skiers from recreational to national standard performed four level skating trials of 6 min duration in random order, each at the same submaximal velocity but with a different skating technique: (1) 'offset' (V1), using a double asymmetrical and asynchronous pole plant as weight is transferred to one ski; (2) 'two-skate' (V2A), where the pole plant is symmetrical; (3) 'one-skate' (V2), where there is a pole plant as weight is transferred to each ski; and (4) 'conventional', without poles. Oxygen uptake (VO2), pulmonary ventilation, the respiratory exchange ratio and heart rate were measured using a K4(b2) portable gas analyser. The aerobic energy cost (VO2/mean speed) and heart rate were higher (P < 0.05) in the one-skate than in the offset condition. This may be explained by the greater and more efficient use of the upper body and the lower variation in centre of gravity velocity in the offset condition. The aerobic energy cost was 5-9% higher (P < 0.01) in the conventional than in the other techniques, probably because of the shorter duration of propulsive forces within a cycle in the conventional skating condition. Moreover, in ski skating, the mechanical efficiency (propulsive forces/total forces) was shown to be higher in the upper than in the lower limbs. The correlation coefficient between performance and aerobic energy cost was significant in the two-skate (r = 0.68, P = 0.02), one-skate (r = 0.72, P = 0.01) and conventional (r = 0.62, P = 0.04) conditions, but not in the offset condition (r = 0.50, P = 0.10). Our results stress the importance of the upper body component in cross-country skiing and that the aerobic energy cost discriminates between skiers of different standards.     

Cultures of running: characteristics and determinants

Based on the studies of Mauss (1935 Mauss, M. 1935. “Les techniques du corps.” Journal de Psychologie 32: 271–293. [Google Scholar]) and Bourdieu (1980 Bourdieu, P. 1980. Le Sens pratique. Paris: Editions de Minuit. [Google Scholar]) on the determination of body techniques by culture and social background, this study seeks to describe the rules, dispositions and habits specific to different forms of athletic running. It is based on a sample of 732 athletes, all of them are the members of French athletics clubs, comprising 220 sprinters, 213 half-distance runners and 299 long-distance runners. Sports practices are different depending on sub-culture affiliation, sociological characteristics and forms of commitment. This being said, simple links between variables should not be transformed into causal connections. Before drawing such conclusions, it is important to identify the nature of the sport studied. This shows that middle-distance and long-distance enthusiasts, traditionally classified in the same family, have less, in common, than those practising sprint and middle distance. These results potentially question the methodological groups and sociological interpretations made by researchers and sports science.     

A deficit in rime awareness in children with Down syndrome

This paper reports 3 studies comparing thereading and phonological skills of childrenwith Down syndrome (DS) and younger normallydeveloping children of similar reading level.In Study 1, the two groups did not differ insight word or nonword reading, but the childrenwith DS did marginally less well on syllablesegmentation, rhyme and phoneme detectiontasks. Group differences in syllable andphoneme awareness appeared attributable todifferences in verbal ability (BPVS, vocabularyknowledge); however, a significant impairmentin rhyme detection remained in an analysis ofsub-groups equated in vocabulary knowledge. Thedeficit in rhyme observed in DS was replicatedin Studies 2 and 3 using simplified tests ofrhyme judgement, with the majority of childrenwith DS performing at chance on the rhymemeasures. In contrast, the two groups did notdiffer in their ability to detect phonemes inany of the 3 studies and performed above chancein initial phoneme detection and alliterationjudgement tasks, although the identification offinal phonemes was at a much lower level. Correlational analyses indicated a relationshipbetween phonological skills and reading inboth groups. However, for children with DS,letter-sound knowledge did not predict readingwhereas it did for normal controls. It issuggested that children with DS do not possessfull phoneme awareness; although they canidentify initial phonemes in words, they do notunderstand phoneme invariance and may rely lesson phonological skills for reading thancontrols.     

Embedding Mathematical Dialogue in Parent–Child Shared Book Reading: A Preliminary Investigation

Research Findings: Shared book reading provides a meaningful context for rich conversations to occur between a child and an adult and offers opportunities for children to be exposed to a range of vocabulary and concepts that often extend beyond their everyday experiences. Few studies have examined parent–child shared book reading as a context for embedding mathematical discussion. The purpose of this study was to examine systematically the effect of training parents to focus on mathematical concepts and vocabulary during shared book reading. Specific research questions were as follows: (a) Did parents increase their use of math talk during shared storybook reading following training? (b) Did parents generalize intervention strategies? And (c) did children increase their use of math talk during shared storybook reading? Results from a yoked multiple-baseline design with 6 dyads indicated variability across the dyads with 2 general patterns. Math talk increased following training for 3 of the dyads, whereas verbal mathematical behavior did not show consistent change for the other 3 dyads. Practice or Policy: Results are discussed in the context of home support for early mathematical development.     

Leveraging Play for Learning and Development: Incorporating Cultural-Evolutionary Insights into Early Educational Practices

There is a renewed scientific interest in the role of childhood in human evolution, pointing to the explorative phase of a human's life history that shapes how children learn and develop. This study presents a synthesis from evolutionary sciences that considers biases in childhood learning through activities in play, exploration, and social interactions. The study argues that childhood education based on this framework diverges from formal education. This framework explains why common misconceptions about childhood learning arise and how to resolve them. Finally, we propose how childhood education can be changed to take advantage of biological biases in learning.
