School entry age and reading achievement in the 2006 Programme for International Student Assessment (PISA)

Evidence regarding the effect of early reading instruction on later reading achievement is unusually sparse, given the emphasis often placed on early and intensive reading instruction. Capitalising on international differences in school entry age (SEA), international reading studies may provide such evidence; however, only one quantitative analysis has been conducted that looked at nine-year olds over 17 years ago. Therefore, data from the reading portion of the 2006 Programme for International Student Assessment (PISA) study were re-analysed. The relative reading achievement—as a function of SEA—of 15-year-old students across 55 countries was investigated, controlling for social and economic differences. Results suggested no significant association between reading achievement and SEA. Theoretical explanations for these findings are discussed.     

A preliminary investigation into the nature of shock absorbency in synthetic sports materials

Tests were conducted on three athletic shoe midsole materials and on three synthetic sports surfaces. All specimens were found to absorb energy when loaded. For a specific maximum load the amount of energy absorbed by each material was found to decrease as the load application rate increased. The materials exhibited different capacities to dissipate energy under the application of the same impulse. This may be a consideration for the injury protection afforded. The development of rheological models from the results of the tests aided an explanation of how force is resisted and energy absorbed by synthetic sports materials. Their shock absorbing properties were associated with the rheological elements of elasticity and viscosity.     

Area Health Education as the foundation for a statewide biomedical communications network

In 1972, the Medical University of South Carolina was awarded a contract to establish four Area Health Education Centers in South Carolina. These centers, based in community hospitals, provide residency programs and clinical instruction for medical, dental, nursing, pharmacy, and allied health students and continuing educational programs for health professionals. A plan for delivering library and other information services to the designated Area Health Education Centers is described.
