Measuring Socioeconomic Status at the School Level

Why is there an increased need for quantitative indicators of student socioeconomic status at the school level? What alternative approaches have been used to measure SES? Can principals accurately estimate the SES distribution of their student populations? How do their estimates correlate with other indexes o f family SES?     

The marketing audit: a new perspective on library services and products

A marketing audit enables a library to look at audiences, services, and products with a structured approach. The audit can be used to assess operations and to provide a framework for ongoing decision making, evaluation, and long-range planning. An approach to the audit process is presented and its application is demonstrated in a case study featuring the American Hospital Association Resource Center.     

The effect of training on aerobic power characteristics of young cross-country skiers

The influences of growth, training and various training methods were investigated by analysing long-term training effects in young cross-country and biathlon skiers (n = 129). Some athletes (n = 49) were studied six times in three years and some at least once a year during a four year period (n = 48). During three summer training periods skiers emphasized either intensive training or distance training or continued to train normally. The results indicated that maximal oxygen uptake (VO2 max) and heart volume increased between 15 and 20 years of age and the most significant changes in heart volume were observed between 16 and 18 years of age. International level skiers were able to increase their VO2 max and heart volume even after 20 years of age. Anaerobic threshold (AT, ml kg-1 min-1) increased like VO2 max but when expressed as a percentage of VO2 max, the AT was similar in every age group over 16 years of age. Intensive training at the intensity of anaerobic threshold or higher was observed to be most effective in producing improvements in VO2 max. Low-intensity distance training was more effective in producing improvements in anaerobic threshold.
