Obesity and Developmental Functioning Among Children Aged 2-4 Years

In developed countries, obesity tends to be associated with worse labor market outcomes. One possible reason is that obesity leads to less human capital formation early in life. This paper investigates the association between obesity and the developmental functioning of children at younger ages (2-4 years) than ever previously examined. Data from the German Socio-Economic Panel Study are used to estimate models of developmental functioning in four critical areas (verbal skills, activities of daily living, motor skills, and social skills) as a function of various measures of weight (including BMI and obesity status) controlling for various child and family characteristics. The findings indicate that, among boys, obesity is a significant risk factor for lagged development in verbal skills, social skills, and activities of daily living. Among girls, weight generally does not have a statistically significant association with these developmental outcomes. Further investigations show that the correlations exist even for those preschool children who spend no time in day care, which implies that the correlation between obesity and developmental functioning cannot be due to discrimination by teachers, classmates, or even day care providers.Obesity, human capital, children, child development, Germany, gender

Asteroid Diameters and Albedos from NEOWISE Reactivation Mission Years 4 and 5

The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has been conducting a two-band thermal infrared survey to detect and characterize asteroids and comets since its reactivation in 2013 December. Using the observations collected during the fourth and fifth years of the survey, our automated pipeline detected candidate moving objects that were verified and reported to the Minor Planet Center. Using these detections, we perform thermal modeling of each object from the near-Earth object (NEO) and Main Belt asteroid (MBA) populations to constrain their sizes. We present thermal model fits of asteroid diameters for 189 NEOs and 5831 MBAs detected during the fourth year of the survey, and 185 NEOs and 5776 MBAs from the fifth year. To date, the NEOWISE Reactivation survey has provided thermal model characterization for 957 unique NEOs. Including all phases of the original Wide-field Infrared Survey Explorer survey brings the total to 1473 unique NEOs that have been characterized between 2010 and the present

Laptops for teachers: An evaluation of the TELA scheme in schools (Years 4 to 6)

The purpose of this evaluation was to investigate the impacts of the Laptops for Teachers Scheme (referred to from here as the TELA scheme) on Years 4 to 6 teachers’ work over a period of three years (2004-2006) and to record emerging changes in laptop use. The investigation focused on the Ministry of Education expectation (Ministry of Education, 2004) that teacher access to a laptop for their individual professional use would lead to gains in confidence and expertise in the use of ICTs, to efficiencies in administration, would contribute to teacher collaboration and support the preparation of high quality lesson resources. It was also anticipated that teacher would use their laptop in the classroom for teaching and learning

Methane (CH₄) flux data for Moidach More. Years 1997 - 1998

Methane (CH4) emission data collected from an extensive pristine portion of raised peat bog located in Moidach More, Morayshire, northeast Scotland (UK). CH4 flux was measured using static chambers, which were sampled on a weekly (late spring to early autumn) to monthly basis (late autumn to early spring), starting in May 1997
