The Summer of Friendship by Fire: A Doctoral Student Reminisces about Lessons in Diversity

The journey toward becoming a multicultural person is not easy and is never finished. As an educational administrator in a tri-cultural state, I felt comfortable that I was proficient in dealing with diversity. Only when I began a doctoral program at a major Texas university was my naivety exposed. I quickly learned that experience in working with diverse populations and the ability to relate effectively to people of different ethnic backgrounds were vastly different. The two years I spent deeply immersed in a multiculturally rich cohort of doctoral students changed me. My eyes were opened to injustices that I had never before seen as I vicariously experienced life through the eyes of the “other.” Today, I am a professor at a regional university. My experiences, focused through the lens of theory, are the basis for the message to my students. I have traveled the road before and can now point the way toward a broader definition of acceptance and tolerance.     

Schooling for self-employment in Kenya: The acquisition of craft skills in and outside schools

Primary schooling will continue to be the terminal stage of education for most Kenyan children, and it will have to prepare them for employment that they will create for themselves. What this might imply for the teaching of craft skills is examined. Soapstone carving was selected as the subject of study because it is an important form of self-employment in western Kenya. The acquisition of craft skills in and outside schools was compared using observational and experimental methods. It is argued that school instruction provides little opportunity to develop competence in carrying out cognitive and psychomotor tasks important to expert performance in this and perhaps many other craft occupations.     

The effects of opposition and gender on knee kinematics and ground reaction force during landing from volleyball block jumps

The aim of this study was to examine the effect of opposition and gender on knee kinematics and ground reaction force during landing from a volleyball block jump. Six female and six male university volleyball players performed two landing tasks: (a) an unopposed and (b) an opposed volleyball block jump and landing. A 12-camera motion analysis system (120 Hz) was used to record knee kinematics, and a force platform (600 Hz) was used to record ground reaction force during landing. The results showed a significant effect for level of opposition in peak normalized ground reaction force (p = .04), knee flexion at ground contact (p = .003), maximum knee flexion (p = .001), and knee flexion range of motion (p = .003). There was a significant effect for gender in maximum knee flexion (p = .01), knee flexion range of motion (p = .001), maximum knee valgus angle (p = .001), and knee valgus range of motion (p = .001). The changes in landing biomechanics as a result of opposition suggest future research on landing mechanics should examine opposed exercises, because opposition may significantly alter neuromuscular responses.     

Influence of pre-exercise glucose ingestion of two concentrations on paraplegic athletes

In this study, we assessed the influence that pre-exercise glucose ingestion of two concentrations has on the physiological responses of paraplegic athletes. Eight men with paraplegia ingested a drink containing 4% (low) or 11% (high) carbohydrate in a randomized double-blind crossover design, 20 min before exercise. The participants performed wheelchair exercise at 65% of peak oxygen uptake for 1 h followed by a 20 min performance test. During both trials, the physiological responses were similar and indicated steady-state exercise. At the onset of exercise, blood glucose concentrations in both trials increased after carbohydrate ingestion (P < 0.05) before returning to resting values after 20 min of exercise and there were no differences between trials. Free fatty acid concentrations increased from rest to 1 h of exercise in both trials, with a greater increase during the low carbohydrate trial that led to a difference in free fatty acids between trials at the end of the 1 h tests (P < 0.05). There was a tendency for the performance distances and power outputs achieved during the high carbohydrate trial to be greater than those achieved during the low carbohydrate trial (P= 0.08). In conclusion, when paraplegic athletes ingested low and high carbohydrate drinks before exercise, the decline in blood glucose concentrations was similar. The tendency for higher blood glucose concentrations, respiratory exchange ratios and power outputs and lower free fatty acid concentrations (P < 0.05) during the high carbohydrate trial suggests that a higher concentration of carbohydrate in a sports drink might be a better choice for paraplegic athletes.
