Carbohydrate and carbohydrate + protein for cycling time-trial performance

Carbohydrate intake during endurance exercise delays the onset of fatigue and improves performance. Two recent cycling studies have reported increased time to exhaustion when protein is ingested together with carbohydrate. The purpose of the present study was to test the hypothesis that ingestion of a carbohydrate + protein beverage will lead to significant improvements in cycling time-trial performance relative to placebo and carbohydrate alone. Thirteen cyclists completed 120 min of constant-load ergometer cycling. Thereafter, participants performed a time-trial in which they completed a set amount of work (7 kJ kg(-1)) as quickly as possible. Participants completed four experimental trials, the first for familiarization and then three randomized, double-blind treatments consisting of a placebo, carbohydrate, and carbohydrate + protein. Participants received 250 ml of beverage every 15 min during the constant-load ride. Time-trial performance for carbohydrate (37.1 min, s = 3.8) was significantly (P < 0.05) faster than placebo (39.7 min, s = 4.6). Time-trial performance for carbohydrate + protein (38.8 min, s = 5.5) was not significantly different from either placebo or carbohydrate. Ingestion of a carbohydrate beverage during two hours of constant-load cycling significantly enhanced subsequent time-trial performance compared with placebo. The carbohydrate + protein beverage provided no additional performance benefit.     

A management program for elective mutism

Behavior modification procedures are described for establishing compliant behavior in elective mutes. The results are discussed for three children to whom the procedure was applied. The length of the training period was two weeks for the first child, twelve days for the second, and six weeks for the third. Two of the three subjects generalized responsive and spontaneous language from the experimental to everyday settings.     

Disaggregated Effects of Device on Score Comparability

The use of tablets for large‐scale testing programs has transitioned from concept to reality for many state testing programs. This study extended previous research on score comparability between tablets and computers with high school students to compare score distributions across devices for reading, math, and science and to evaluate device effects for gender and ethnicity subgroups. Results indicated no significant differences between tablets and computers for math and science. For reading, a small device effect favoring tablets was found for the middle to lower part of the score distribution. This effect seemed to be driven by increases in performance for male students when testing on tablets. No interactions of device with ethnicity were observed. Consistent with previous research, this study provides additional evidence for a relatively high degree of comparability between tablets and computers.     

Educating the educators: developing those who support learning for students with additional learning needs

This article reports findings from a research project which developed and introduced the Enhanced Learning Support Assistant Programme (ELSAP) as a source of professional development for learning support assistants who were supporting students with additional learning needs in a college of further education in England. The purpose of this article is to share findings from the project and to highlight the benefits experienced when learning support assistants can participate in professional development activity. The research project was a mixed methods study with participants drawn from learning support assistants within one college of further education in England. Data were collected throughout the 14‐week intervention. Findings indicate that the programme had a positive effect on participants' confidence, sense of professional identify and of being valued, as well as improving their ability to perform their role.     

Rediscovering the Role of Interscholastic Sports

The goals of today's school athletic programs are vastly different from the original intentions of the administrators who established the first interscholastic athletic teams. For athletics to be anything more than a drain on school and taxpayer resources, these programs must undergo serious changes.
