A Journey towards Collaborative Culture Development: How to Be Weightless Despite Academic Gravity

In science, gravity refers to the universal force of attraction acting on and between all matter. No one on earth can escape the force of gravity. In a similar vein, the stringent requirements of publications, research grants, and research output in the academic world can be metaphorically described as “academic gravity,” the force of which pushes university academics to struggle and strive in pursuit of excellence just to survive in the changing landscape of higher education governed by neo-liberalism and managerialism. This article describes the journey of a junior academic staff member in an Asian university as he coped with various difficulties in establishing a collaborative culture in his department (i.e., the Faculty of Education). Working with a senior colleague (Sunshine-mother hereafter) in the same department, Author 1 began to recognize the importance of collegial collaboration in teacher education generally and in his academic life specifically. However, although he tried his utmost to develop a culture of collaboration amongst his colleagues, he struggled to cope with the tension and stress exerted by academic gravity (i.e., publication production and the pursuit of tenure). Drawing on data collected from a teaching development project and adopting a reflective autobiographic approach, this article delineates the collaborative relationship between Author 1 and Sunshine-mother, exemplifying the important roles that coaching and a free rein (i.e., weightlessness) play in the development of junior teacher-educators under the strong pressure of academic gravity.     

Behavior problems of children as perceived by teachers,mental health professionals,and children

The objective of this study was to examine current teacher and mental health professional ratings regarding the relative seriousness of 50 specific children's behavior problems and to compare the results to those found by Wickman (1928). Wickman's questionnaire and procedures were replicated to insure comparability. A second objective was to extend Wickman's work so that children's ratings of their own behavior problems may be ascertained. An increase in the similarity between teachers' and mental health professionals' judgements concerning the seriousness of specific children's behavior problems was found. These findings were attributable to a more pragmatic approach taken by mental health professionals. A very high agreement on the seriousness of specific behavior problem ratings was demonstrated by children and teachers. This similarity may be the result of proximity of effects.     

Regression Analysis for Prediction: Understanding the Process

Research related to cardiorespiratory fitness often uses regression analysis in order to predict cardiorespiratory status or future outcomes. Reading these studies can be tedious and difficult unless the reader has a thorough understanding of the processes used in the analysis. This feature seeks to “simplify” the process of regression analysis for prediction in order to help readers understand this type of study more easily. Examples of the use of this statistical technique are provided in order to facilitate better understanding.     

Heart rates of high school physical education students during team sports, individual sports, and fitness activities

This study examined how activity type influenced heart rates and time spent in target heart rate zones of high school students participating in physical education classes. Significantly higher average heart rates existed for fitness (142 +/- 24 beats per minute [bpm]) compared to team (118 +/- 24 bpm) or individual (114 +/- 18) activities. Similar results occurred for the percentage of activity time spent within a target heart rate zone (fitness 81.7 +/- 15.9%, individual 68.4 +/- 30.5%, and team 60.6 +/- 30.5%). Boys attained higher heart rates during team activities, while female students had higher rates during individual activities indicating male and female adolescents respond differently to activity types. The highest mean heart rates were observed during fitness activities.     

Making Plans for Michael: providing for a student with moderate learning difficulties in a secondary academy

The profile of a student with learning difficulties is described and also the learning context in 2017. Previous models of provision are then described in terms of their aetiology with discussion of strengths and shortcomings. Some influential features of curriculum planning and delivery are identified. A model of provision involving specific literacy teaching and differentiation is advocated.     

Nutritional strategies for promoting fat utilization and delaying the onset of fatigue during prolonged exercise

Carbohydrate ingestion before and during endurance exercise delays the onset of fatigue (reduced power output). Therefore, endurance athletes are recommended to ingest diets high in carbohydrate (70% of total energy) during competition and training. However, increasing the availability of plasma free fatty acids has been shown to slow the rate of muscle and liver glycogen depletion by promoting the utilization of fat. Ingested fat, in the form of long-chain (C 16-22 ) triacylglycerols, is largely unavailable during acute exercise, but medium-chain (C 8-10 ) triacylglycerols are rapidly absorbed and oxidized. We have shown that the ingestion of medium-chain triacylglycerols in combination with carbohydrate spares muscle carbohydrate stores during 2 h of submaximal (< 70% VO 2 peak) cycling exercise, and improves 40 km time-trial performance. These data suggest that by combining carbohydrate and medium-chain triacylglycerols as a pre-exercise supplement and as a nutritional supplement during exercise, fat oxidation will be enhanced, and endogenous carbohydrate will be spared. We have also examined the chronic metabolic adaptations and effects on substrate utilization and endurance performance when athletes ingest a diet that is high in fat (> 70% by energy). Dietary fat adaptation for a period of at least 2-4 weeks has resulted in a nearly two-fold increase in resistance to fatigue during prolonged, low- to moderate-intensity cycling (< 70% VO 2 peak). Moreover, preliminary studies suggest that mean cycling 20 km time-trial performance following prolonged submaximal exercise is enhanced by 80 s after dietary fat adaptation and 3 days of carbohydrate loading. Thus the relative contribution of fuel substrate to prolonged endurance activity may be modified by training, pre-exercise feeding, habitual diet, or by artificially altering the hormonal milieu or the availability of circulating fuels. The time course and dose-response of these effects on maximizing the oxidative contribution of fat for exercise metabolism and in exercise performance have not been systematically studied during moderate- to high-intensity exercise in humans.
