BACKGROUND Although numerous investigations have indicated that social participation (SP) has positive effects on the health of older adults, there have been few studies on its negative health consequences. We examined the cross-sectional associations of the type, frequency, and autonomy for SP with physical and mental health. METHODS The analytical subjects were 5126 males and 7006 females w...

We consider a problem of repeatedly scheduling n jobs on m parallel machines. Each job is associated with a profit that is gained each time the job is completed, and the goal is to maximize the average profit per time unit. Once the processing of a job is completed, it goes on vacation and returns to the system, ready to be processed again, only after its vacation is over. This problem has many...

This study examined the interpretation of English anaphora by native Spanish speakers and potential transfer pragmatic lexical requirements into English. It further evaluated whether appropriate contextual information might prime preferred such constructions. Pragmatic rules governing co-indexation in constructions differ substantially operate quite differently two languages. require obligatory...

This study is about a set of appropriate nouns Napp in French. A sequence is said to be appropriate to a given context [Z.S. Harris, 1970, 1976, pp. 113-114] if it has the highest plausibility of occurrence in that context, and can therefore be reduced to zero. In French, the notion of appropriateness is often connected with a metonymical restructuration of the subject [A. Guillet, Ch. Leclère,...

We determine a class of triple systems such that each must occur in a triple system with uncountable chromatic number that omits T0 (the system consisting of two triples on four vertices). This class contains all odd circuit of length ≥ 7. We also show that consistently there are two finite triple systems such that they can separately be omitted by uncountably chromatic triple systems but not b...

We tested the hypothesis that saccade gains adapt to minimize error between the visual target and the saccade endpoint of every saccade we make even when the errors on sequential saccades are not directionally consistent. We utilized a state-space model that estimated the degree to which saccade gains were modified by the magnitude and direction of errors made on the previous trial. Importantly...
