Relationship between BMI, physical fitness, and motor skills in youth with mild intellectual disabilities

Abstract: The negative impact of obesity on physical fitness and motor abilities has been documented in youth of various ages; however, this issue has not been explored in youth with mild intellectual disabilities (ID). Youth with ID are considered more overweight, less physically fit, and less motor proficient than peers without ID, so it is important to determine if these variables are associated in this population. The purpose of this study was to examine the relationship between body mass index (BMI), physical fitness, and motor skills in a large sample of youth with mild ID. A systematic, stratified sampling method was used to select 444 youth with mild ID, aged 6–18 years, from eight special education schools in Hong Kong. Physical fitness was assessed using items from the national Hong Kong assessment: 6- (ages 6–8 years) or 9- (ages 9–18 years) minute run, sit-up, isometric push-up, sit and reach, and sum of skinfold. Functional motor skills were assessed in 244 youth from the fitness sample using the Test of Gross Motor Development-II. Subjects were categorized into normal or overweight/obese BMI groups based on international cutoff points. Approximately 20% of the sample was classified as overweight/obese (average BMI normal=17.47±2.69; overweight/obese=24.78±4.05). ANCOVA controlling for age and gender revealed group differences in the run (P=0.001) and push-ups (P=0.05), but not in the motor or other fitness variables. After controlling for age and gender, BMI was correlated with the run (r=−0.27, P < 0.001) and push ups (r=−0.18, P=0.008). Age and gender were entered as the first block in hierarchical regression and accounted for most of the variance in all dependent variables, except sit and reach. The inclusion of BMI in the second block added to the model for run and push-ups only (ΔR2 run=0.04, push-ups=0.03, P<0.001). Overweight/obesity is minimally associated with aerobic fitness and muscular strength in youth with mild ID. BMI did not impact other fitness measures (sit-up, sit and reach) or motor skills in the sample. The undesirable level of overweight/obesity in this sample requires increased attention and immediate intervention.

Quantum teleportation of an entangled state

Abstract: We consider the teleportation of entangled two-particle and multiparticle states and present a scheme for the teleportation that may be suitable for both entangled atomic states or field states inside high-Q cavities.

Supervisor—Subordinate Guanxi and Employee Work Outcomes: The Mediating Role of Job Satisfaction

Abstract: In this study, we attempt to explain the divergent results found in the relationships between supervisor–subordinate guanxi and employee work outcomes. Specifically, we propose that the relationships between supervisor–subordinate guanxi and participatory management, turnover intentions, and organizational commitment are mediated by job satisfaction. Based on the data collected from a sample of 196 employees of three local manufacturing firms in Zhejiang Province, China, we found that job satisfaction fully mediated the effects of supervisor–subordinate guanxi on participatory management and intentions to leave, but partially mediated the relationship between supervisor–subordinate guanxi and organizational commitment. Theoretical and practical implications are discussed.

A Mesoporous Pt/TiO2 Nanoarchitecture with Catalytic and Photocatalytic Functions

Abstract: A novel metal/semiconductor nanocomposite with catalytic and photocatalytic functions has been prepared. The new material consists of highly dispersed platinum (Pt) nanoparticles embedded in a cubic mesoporous nanocrystalline anatase (meso-nc-TiO2) thin film. The porous thin film possesses a narrow pore-size distribution and a large surface area. The diameter of the Pt cluster can be controlled to below 5 nm, and the high dispersion of these clusters gives rise to catalytic activity for the oxidation of carbon monoxide, an important reaction for automobile exhaust treatment. This novel ordered mesoporous Pt/TiO2 nanoarchitecture is also a promising photochemical material, as demonstrated by the photo-driven killing of Micrococcus lylae cells on the film.
