Comparison of Hydrostatic Weighing at Residual Volume and Total Lung Capacity in Children

Abstract

The influence of perceptions of the motivational climate and perceived ability on situational motivation and the physical activity behavior of 213 male and 229 female adolescent physical education students (M age= 12.56 years; SD = 0.96) was examined over a 3-day period. A significant age by gender interaction emerged, with physical activity declining from the sixth to eighth grade. The decline was more pronounced among female than male students. Perceptions of a mastery climate were strongly related to more self-determined forms of situational motivation. In contrast, perceptions of a performance climate were strongly related to less self-determined forms of situational motivation. Results of a hierarchical regression analysis revealed gender, perceived ability, and perceptions of a mastery climate to explain a significant amount of variance in physical activity. These findings suggest that promoting a mastery oriented motivational climate in physical education will foster self-determined situational motivation and physical activity.     

Establishing the Test–Retest Reliability & Concurrent Validity for the Repeat Ice Skating Test (RIST) in Adolescent Male Ice Hockey Players

In this study the authors examine the test–retest reliability and concurrent validity of the Repeat Ice Skating Test (RIST). This was an on-ice field anaerobic test that measured average peak power and was validated with 3 anaerobic lab tests: (a) vertical jump, (b) the Margaria–Kalamen stair test, and (c) the Wingate Anaerobic Test. The participants (n?=?14) were 11- to 12-year-old males selected from a Peewee “A” level ice hockey team (Thunder Bay, Canada). The results of the test–retest reliability estimation showed that the RIST was a reliable test at measuring average peak power in watts (R = .99, C.I._95% = 0.97 to 0.99) and watts per kilogram (R = .98, C.I._95% = 0.94 to 0.99). The RIST was also a valid test when correlated with the 3 anaerobic lab tests for measuring peak power in watts: vertical jump (r = .86, C.I._95% = 0.72 to 0.94), Margaria–Kalamen stair test (r = .66, C.I._95% = 0.39 to 0.83) and Wingate Anaerobic Test (r = .86, C.I._95% = 0.72 to 0.93). The test is considered promising because it does not require any specific equipment, and is a sport-specific, on-ice test, that can be administered during a regular ice hockey practice session.     

Gerontological Education in Undergraduate Nursing Programs: An Australian Perspective

Literature reveals difficulties in preparing nurses to care for older people. This article reports a study that aimed to facilitate positive changes in gerontological education in an undergraduate nursing program by identifying barriers and effective actions. A critical research approach was applied to the study. Data were mainly collected through focus groups. A total of five barriers were identified in gerontological education in an undergraduate nursing program. Actions which may address these barriers were explored. Critical reflection on educational practice based on partnerships between education and service sectors has the potential of leading an educational reform in gerontological nursing.     

论外语教学行动研究的重要性

This article mainly gives a brief introduction to the general idea of Action Research and the wayshow it can be applied in the foreign languages teaching. A very practical teaching approach can be derived fromthe study of Action Research,and so we can do something better to manage how to teach to learn and how tolearn to teach well in the real situation.     

The adjustment of national education systems to a knowledge‐based economy: a new approach

In his article ‘Globalisation, the Learning Society, and Comparative Education’, Peter Jarvis recommends lifelong learning in the period of globalisation as a topic ripe for scholarly research. In particular, he argues for the examination of the extent of lifelong learning around the world and its relation to different levels of employment. This article contributes to this line of inquiry by analysing how education policies facilitate adjustment to economic change and examining how advanced industrialised countries (AICs) compare in their promotion. Principal component analysis is used to construct indices for education systems that reflect these two objectives, and the results reveal considerable cross‐national variation. The Nordic countries appear well‐positioned to cope with changed skill needs. A closer look at the cases of Denmark and Italy portrays how a national education system can facilitate or hinder adaptation, respectively.
