The present study evaluated the effectiveness of a Social Problem Solving (SPS) competence training program for kindergartners, and examined relationships between SPS skill and adjustment gains. Subjects included 63 suburban middle-classSs from three classes, who participated in the 42 lesson program, and 46 comparisonSs from two classes, who did not. Subjects were evaluated on problem solving, peer sociometric and teacher adjustment ratings. Program children gave significantly more, and better, solutions, and fewer irrelevant responses to interpersonal problems. They also improved more than comparisonSs on several teacher-rated dimensions of adjustment. Direct linkages between skill and adjustment gains, however, were not found.

Conjugate Gradient (CG) methods are widely used for solving large-scale nonlinear systems of equations arising in various real-life applications due to their efficiency in employing vector operations. However, the global convergence analysis of CG methods remains a significant challenge. In response, this study proposes scaled versions of CG parameters based on the renowned Barzilai-Borwein approach for solving convex-constrained monotone nonlinear equations.

Word problems are essential for math learning and education, bridging numerical knowledge with real-world applications. Despite their importance, the neural mechanisms underlying word problem solving, especially in children, remain poorly understood. Here, we examine children's cognitive and brain response profiles for arithmetic word problems (AWPs), which involve one-step mathematical operations, and compare them with nonarithmetic word problems (NWPs), structured as parallel narratives without numerical operations.

The nature and basis of creative thought has been the subject of wide-ranging inquiry. It is well established that people tend to struggle to solve problems that require an insight-and that this limitation is not readily alleviated. What can help produce more successful creative cognition? We propose a benefit from increased focus on the relations that hold between the elements of a problem situation.

Piecewise-deterministic Markov processes combine continuous in time dynamics with jump events, the rates of which generally depend on the continuous variables and thus are not constants. This leads to a problem in a Monte-Carlo simulation of such a system, where, at each step, one must find the time instant of the next event. The latter is determined by an integral equation and usually is rather slow in numerical implementation.
