The study describes the phenomenon of inclusive physical education from perspective students with disabilities. experience 9 elementary school-aged disabilities (6 males and 3 females a mean age 11 years, 1 month) was captured by way focus group interviews, field notes, participant drawings. thematic analysis uncovered persistent dichotomy in how participants experienced education. Good days were revealed themes sense belonging, skillful participation, sharing benefits. Bad overshadowed...
An activity deficit hypothesis was posited that children with movement difficulties are less physically active during recess than age- and gender-matched controls without difficulties. Criteria used in identifying were (a) a score of at least 4 on the Test Motor Impairment, (b) regular physical education student, (c) age 80 to 109 months. observational study conducted over 2-month period settings 52 subjects. Findings revealed time, vigorously often, played often large playground equipment,...
This study explored the perspectives of children with disabilities regarding concept inclusion in physical activity. Participants were (two girls, nine boys, M age = 10 years, five months, range: 8–12 years) disabilities, including cerebral palsy, fine and gross motor delays, developmental coordination disorder, muscular dystrophy, nemaline myopathy, brachial plexus injury, severe asthma. Children’s on activity (e.g., sports, games, play) through semistructured interviews. Interviews...
Abstract Radioisotope power systems utilising americium-241 as a source of heat have been under development in Europe part European Space Agency funded programme since 2009. The aim is to develop all the building blocks that would enable launch and operate deep space planetary missions environments where use solar or alternative generation technologies challenging. Although some technical policy work activity predate ESA programme, maturity technology has now reached level it can be...
The investigation explored 12 adults’ past experiences of physical awkwardness. Hermeneutic phenomenology, a descriptive and interpretative methodology, uncovered feelings meanings associated with childhood reminiscences awkwardness, from 18 semi-structured interviews. Findings focus upon four themes, namely: “failing falling,” “hurt humiliation,” “worrying wondering,” seeking ways “avoiding awkwardness” in the future. A heightened awareness subjective lived experience those who are awkward...
Inclusion in activity at recess can have important implications for the health and physical, social, cognitive development of children, according to play theorists (Pellegrini, 1995). This study examined whether children described their decisions (and those fictitious others) engage activities achievement terms consistent with expectancy-value theory (Eccles, Wigfield & Schiefele, 1998). Ten Grade 3 different patterns engagement did confirm that attainment, interest, utility, cost values...
The purpose was to develop a valid protocol for use by physical educators in assessing whether children suspected of having developmental coordination disorder (DCD) meet the American Psychiatric Association (1994) diagnostic criterion interference activities daily living when is defined as culturally subaverage engagement play (ADL-PP) on playground. Participants were 136 (75 girls, 61 boys) from Grades 1 4 at three elementary schools Canada. Data collected two ways: (a) administrations an...
This study explored the relationship between perceived physical competence and awkwardness in an effort to gain further understanding of effects motor incompetence on behavior. Subjects included 195 children Grades 3 through 6. Multiple regression analysis found that gender, importance attached competence, interaction severity grade were significant predictors perceptions competence. As expected, males reported higher than females. In addition, rating subjects their Investigation revealed...
AbstractPrimary objectives: To analyse the situational and contextual factors surrounding concussions head blows in Taekwondo.Methods procedures: Prospective design. Direct observation, subject interview videotape recording used. A total of 2328 competitors participated 2001 tournament, South Korea. All matches were recorded on videotape. recipients interviewed by athletic therapists researcher immediately after match. The videotapes analysed.Results: 1009 including analysed. Head most...
The individualized nature of instructional programs for the mentally handicapped often makes group designs inappropriate in adapted physical activity research. Single-subject time-series are suitable use investigating acquisition, maintenance, and generalization motor skills when research involves small numbers subjects. These require collection data before, during or after treatment. Three single-subject described illustrated with from studies PREP Play Program, an program young children at...
Radioisotope power systems (RPSs) have transformed our ability to explore the solar system. RPSs been in existence for almost seven decades. Most missions utilized 238Pu as radioisotope of choice generate electrical and produce heat operation thermal management spacecraft systems. In Europe, past decade 241Am has selected RPS research programs. This paper hypothesizes that inclusion small quantities relatively short-lived radioisotopes such 232U 244Cm, particularly when dealing with...
This study investigated whether the TOMI (Stott, Moyes, & Henderson, 1984), a motor skills test recommended for identification of children who are physically awkward (Sugden, 1985; Wall, Reid, Paton, 1990), contains biased items. Findings by Causgrove and Watkinson (1993) indicated that an unexpectedly high proportion girls from Grades 3 to 6 were identified as awkward, authors suggested may be in favor boys. In present study, this suggestion was through comparison performances subtest...
Radioisotope heater units (RHU) and radioisotope thermoelectric generators (RTG) are currently being developed for the ESA power system program. The state-of-the-art USA Russian systems is to use plutonium-238 as fuel; however, applications americium-241 has been selected due its availability relatively cost-effective production in European context. proposed designs implement a multi-layer containment approach safety reasons, with platinum-rhodium alloy inner of fuel carbon-based materials...
Radioisotope thermoelectric generators (RTG) and heater units (RHU) systems are being developed in Europe as part of a European Space Agency (ESA) funded program. Aimed at enabling or significantly enhancing space science exploration missions, these rely on the cost-effective production americium-241 for fuel. The use an iterative approach application lean methodologies development have been focus this technology Isotope containment architectures and, case RTG systems, bismuth telluride...
Over the last several years there has been a mutually beneficial ongoing technical interchange between U.K and U.S. related to various aspects of space radioisotope power systems (RPS). While this primarily focused on materials based activities, it also included some safety, environmental, lessons learned during application RPSs by fifty years. Recent joint RPS endeavors have centered development possible "cold" ceramic surrogate for 238PuO2 241AmOx irradiation thermoelectrics other at...
