Studies of the familial association of physical activity and sedentary behavior have increased in recent years. However, there is a lack of studies that have objectively examined the correlates between parents, grandparents, and childrens' PA. Therefore, the purpose of this study was to measure PA using accelerometers to determine the extent to which PA and SB correlate among parents, grandparents, and children. A sample of 169 children between 11 and 14 years, 225 parents, and 52 grandparents were recruited for the (...) current study. Accelerometers RM42 were used to determine PA levels of children, parents, and grandparents. Epoch length was 6 s. Mothers' moderate-to-vigorous PA was associated with children's MVPA of children's MVPA. In contrast, grandfathers' sedentary behavior was a significant predictor of children's sedentary behavior. The results of the current study suggest that parental involvement in PA, particularly by mothers, is important for children's PA and, accordingly, healthy outcomes. (shrink)

Edition of Bentley’s marginal annotations on the „Disticha Catonis“ from a copy of the editio Scaligerana of 1598, now in the British Library (shelf-mark 680. a. 17), with explanatory notes and critical discussion. His conjectures, although not always convincing, reveal how difficult to understand the transmitted text often is. Four of his notes, slightly altered, can be found without name in Dutch editions of the 18 th century, but the evidence is too sketchy to draw definite conclusions. A collation of (...) four Mss. he added appears elsewhere: in a copy of the editio Leidensis of 1626, held by the Bodleian Library, and among 18 th century Dutch scholars. It is likely to go back to Nicolaus Heinsius. (shrink)

Statistical physics cannot explain why a thermodynamic arrow of time exists, unless one postulates very special and unnatural initial conditions. Yet, we argue that statistical physics can explain why the thermodynamic arrow of time is universal, i.e., why the arrow points in the same direction everywhere. Namely, if two subsystems have opposite arrow-directions at a particular time, the interaction between them makes the configuration statistically unstable and causes a decay towards a system with a universal direction of the arrow of (...) time. We present general qualitative arguments for that claim and support them by a detailed analysis of a toy model based on the baker’s map. (shrink)
