Aim was to identify critical load (CL) in young and elderly apparently healthy male cohorts. To contrast the metabolic, cardiovascular and perceptual responses on CL according to age. We evaluated 12 young (23 ± 3 years) and 10 elderly (70 ± 2 years) apparently healthy active males, who underwent: (1) 1 repetition maximum (1RM) test on a 45° Leg Press; (2) on different days, three high-intensity resistance exercise constant load tests (60%, 75% and 90% 1RM) until fatigue (Tlim). Absolute values of both the CL asymptote and curvature constant (kg) were significantly lower in elderly subjects (P < 0.05). In contrast, elderly subjects demonstrated a significantly higher number of repetitions at CL when compared with young subjects (P < 0.05). As expected, oxygen uptake (VO₂) and heart rate (HR) during maximal aerobic exercise testing were significantly reduced in older subjects. However, percent-predicted aerobic capacity were higher in older subjects (P < 0.05). In addition, blood lactate ([La^?]) corrected to Tlim and rating of perceived exertion values were greater in younger subjects at all intensities (P < 0.05). These findings, despite reduced force production in older subjects, endurance-related parameters are well preserved according to age-adjusted percent-predicted values in apparently healthy males.  相似文献   

Decisions Hispanic families make after the identification of deafness     

Steinberg A  Bain L  Li Y  Delgado G  Ruperto V 《Journal of deaf studies and deaf education》2003,8(3):291-314

This study examines the decision-making process for Hispanic families living in the United States who have a child with a hearing loss. Twenty-nine families in four geographical areas shared their experiences in searching for appropriate interventions and making choices regarding communication and education. We explored the impact of language, culture, minority status, and access to information and services on the decision-making process. The results indicate that the deliberations of Hispanic parents are often complicated by language and cultural barriers and by limited access to information, resources, and a full range of options. The communication method chosen tended to be the one recommended by professionals, usually a combination of spoken English and sign language. Parents frequently expressed the hope that their child would learn Spanish as well. These subjects displayed a higher degree of assertiveness in obtaining services for their children than other studies have suggested.  相似文献   

Using Constructivist Instructional Design Featured in Two Online Courses: Notes From the Field     

Vivian Rossner‐Merrill  Drew Parker  Carolyn Mamchur  Stephanie Chu 《Educational Media International》2013,50(4):282-288

Abstract

We thought that the close integration of theory and practice offered by constructivism promises unique opportunities to maximize learning in online courses using interactive software as the primary medium of communication. The purpose of this paper, therefore, is to examine the ‘goodness of fit’ between principles drawn from constructivist theories and the design and implementation of the interactive online course.  相似文献   

Stressors,family environment and coping styles as predictors of educational and psychosocial adjustment in Palestinian children     

Vivian Khamis 《Educational studies》2013,39(4):371-384

This study investigated the contributions of child and parents’ sociodemographics, daily stressors, family environment, and coping strategies, to academic achievement, cognitive functioning and aggression in a sample of 600 children at the intermediate grade levels from Gaza Strip. Each of the predictor variables exhibited a different pattern of relations with the outcome domains. Although the study highlights the negative consequences of stress on children’s development, certain daily stressors had a positive effect. Optimal family relationships predicted better developmental outcomes. More emphasis on personal growth, control and organisation in the family predicted less optimal child development except for personal growth and achievement. More reliance on positive coping and less reliance on negative coping is associated with better academic achievement. The clinical and research implications of the findings are discussed.  相似文献   

Partnership for Faith-Based Leadership Development: An Educational Model     

Janis Fine  Vivian Hopp Gordon  Marla Susman Israel 《The Educational forum》2013,77(2):138-150

Parochial school leaders traditionally rise from the ranks of the teaching staff into the principal position, even if unprepared. Through a unique collaborative model, an outside partner and a university developed a program for formally preparing individuals to be Jewish day school leaders. The process of creating this model resulted in a reconceptualization of school leadership.  相似文献

Changing from a special school to an inclusion service     

Carol Bannister  Vivienne Sharland  Vivian Upton  David Walker  & Gary Thomas 《British Journal of Special Education》1998,25(2):65-69

Members of the Somerset Inclusion Project and Gary Thomas (professor and reader in education at the University of the West of England, Bristol) discuss the need for schools to become more inclusive in response to the Government's recent Green Paper (DfEE, 1997), which emphasises that special schools need to work in different ways and to provide services to local mainstream schools. The notion that inclusion is right and segregation is wrong led the staff to convert the Princess Margaret School (PMS) in Taunton, Somerset to an inclusion service.  相似文献
