Somatotype, Accumulated Workload, and Fitness Parameters in Elite Youth Players: Associations with Playing Position
The purpose of this study was three-fold: (1) to describe anthropometric, maturation, and
somatotype differences of players based on playing positions; (2) to analyze variations of accumulated
load training (AcL) and fitness parameters between playing positions; and finally (3) to explain the
variation of maximal oxygen uptake (VO2max) and peak power (PP) through the AcL, body fat (BF),
maturity, somatotype and fitness levels. Twenty-seven male youth soccer players under-16 were
divided by the following positions participated in this study: six central midfielders, four wingers
(WG), five forwards, eight defenders, and four goalkeepers (GK). They were evaluated on two
occasions: pre-season and after-season. Height, sitting height, body mass, BF, girths, percentage of BF
(BF%), lean body mass, maturity, somatotype, sprint test, change of direction test, Yo-Yo intermittent
recovery test level 1, Wingate, PP, VO2max and fatigue index were assessed. Then, AcL was monitored
during training sessions. The main results revealed significant differences between player positions
for maturity offset (p = 0.001), for BF (p = 0.006), BF% (p = 0.015), and lean body mass kg (p = 0.003).
Also, there were significant differences for AcL and fatigue index in pre-season between player
positions (p < 0.05). In addition, there were some significant differences in pre- and after-season
for VO2max and PP between player positions (p < 0.05). In conclusion, GK showed higher values in
anthropometric, body composition variables and maturity offset compared to the other positions,
while WG presented lower levels of BF. In pre-season, there were more differences by player positions
for the different variables analyzed than after-season that reinforces the tactical role of the positions,
and the emphasis in increased load in the beginning of the season. This study could be used by
coaches, staff, and researchers as a reference for athletes of the same sex, age, and competitive level.Portuguese Foundation for Science and Technology, I.P., Grant/Award Number UIDP/

The Global Child: A Roadmap for Becoming Culturally Responsive Educators
The program strategies and the assessment tools encourage early childhood teachers to adopt 26 strategies across three competency areas: 1) classroom design; 2) teachersā rhythm and temperament; and 3) instructional strategies during the 10-month program year. Mentors are assigned to each teaching team and through supportive site visits and assessment visits help the teams change their thinking and practices to be more culturally and linguistically responsive

'Playing the game called writing': children's views and voices
Collects primary pupils' views of themselves as writers and their preferences, attitudes and awareness of the source of their ideas in the context of England's National Literacy Strategy. Underlines the importance of listening to pupils' views about literacy, in order to create a more open dialogue about language and learning, and to negotiate the content of the curriculum in response to their perspectives

The Childrenās Perspectives Protocol: A participatory approach to studying child work issues
This is the summary of a research protocol constructed as part of the Radda Barnen project "Childrenās perspectives on their working lives", originally published in 1998. It provided the framework for local investigators carrying-out the initial study with 50 groups of working children in diverse occupations in Bangladesh, Ethiopia, The Philippines and Central America.
ā¢ The protocol was designed to inform popular assumptions about the impact of work in children's lives with evidence on children's own perception of their situation;
ā¢ The protocol is applied in ways sensitive to the local circumstances of working children, and their preferred ways of communicating their experiences;
ā¢ The protocol can be adapted to provide systematic, detailed accounts of specific occupational situations in ways that can inform context-appropriate interventions
Youth Development/Youth Service Status Report
During the 1994-1995 school year, over 80% of Minnesota\u27s school districts chose to participate in Youth Development/Youth Service that has been an integral part of Community Education since 1987. Out of the 365 operating school districts in Minnesota, 290 districts applied for and received the $1.00 per capita authorized by the Minnesota State Legislature to implement a Youth Development Plan approved by the (local) school board and to provide a youth service program
