Seventy children were observed during structured play with their primary professional caregivers and three peers in the child care center and with their primary caregiving parents at home at 15 and 23 months of age. The same structured play tasks were used in the two settings and the quality of the children's interactions with caregivers and parents was rated using the same 7-point scales. As e...

Dedicated to T. Rivlin on the occasion of his 70th birthday Lower and upper bounds are given for the trace of the inverse tr(A ?1) and the determinant det(A) of a symmetric positive deenite matrix A. They are derived by applying Gaussian quadrature and related theory. The bounds for det(A) appears to be new. For the bounds of tr(A ?1), the Kantorovich inequality is available for providing such ...

Suppose Alice and Bob make local two-outcome measurements on a shared entangled state. For any d, we show that there are correlations that can only be reproduced if the local dimension is at least d. This resolves a conjecture of Brunner et al. [Phys. Rev. Lett. 100, 210503 (2008)] and establishes that the amount of entanglement required to maximally violate a Bell inequality must depend on the...

In this note we present a new concept of well-posedness for Optimization Problems with constraints described by parametric Variational Inequalities or parametric Minimum Problems. We investigate some classes of operators and functions that ensure this type of wellposedness.

Abstract This paper explores the interaction between ne-grained connguration management, ver-sioning and traceability. Taken individually, the underlying concepts are relatively simple , but taken in conjunction the situation becomes quite complex. This paper presents...

Abstract Let μ be a Borel measure on R which may be non doubling. The only condition that μ must satisfy is μ(B(x, r)) ≤ Cr for all x ∈ R, r > 0 and for some fixed n with 0 < n ≤ d. In this paper we introduce a maximal operator N , which coincides with the maximal Hardy-Littlewood operator if μ(B(x, r)) ≈ r for x ∈ supp(μ), and we show that all n-dimensional Calderón-Zygmund operators are bound...

Fundamental properties for the Tsallis relative entropy in both classical and quantum systems are studied. As one of our main results, we give the parametric extension of the trace inequality between the quantum relative entropy and the minus of the trace of the relative operator entropy given by Hiai and Petz. The monotonicity of the quantum Tsallis relative entropy for the trace preserving co...

PURPOSE Socioeconomic inequality has been associated with higher levels of morbidity and mortality. This study explores the role of absolute and relative deprivation in predicting late-life depression on both individual and country levels. DESIGN AND METHODS Country- and individual-level inequality indicators were used in multivariate logistic regression and in relative indexes of inequality....

In an attempt to learn the stimulus site of the EER, the following series of experiments was performed. (1) The effect of dark adaptation on EER and VER was determined. The effect was found to be negligible. (2) The effect of eliciting the electric phosphene on the course of dark adaptation was determined. Under our conditions there was no effect. (3) The effect of ambient light on amplitude of...

where λ1 ≥ · · · ≥ λn > 0 are the eigenvalues of A. It is a very useful tool to study the inefficiency of the ordinary least-squares estimate with one regressor in the linear model. Watson 1 introduced the ratio of the variance of the best linear unbiased estimator to the variance of the ordinary least-squares estimator. Such a lower bound of this ratio was provided by Kantorovich inequality 1....
