In this paper, we address a particular variation of the Turán problem for the hypercube. Alon, Krech and Szabó (2007) asked “In an n-dimensional hypercube, Qn, and for ` < d < n, what is the size of a smallest set, S, of Q`’s so that every Qd contains at least one member of S?” Likewise, they asked a similar Ramsey type question: “What is the largest number of colors that we can use to color th...

BACKGROUND Area deprivation negatively affects health and lifestyles, among which child behaviours. The latter may aggravate the effects of area deprivation on parental health due to higher rates of parenting stress. However, evidence on the influence of the living environment on parenting stress is mostly lacking. The aim of this study was to examine the impact of area deprivation and urbaniza...

We describe a general framework for covering concepts using terminologies and briefly present the already investigated instances of this framework. Then, we formalize the best covering problem in the context of the ALN language, in which the difference operation is not semantically unique, and sketches the technique to solve the underlying computation problems.

BACKGROUND Adolescent mental health problems are associated with a range of adverse outcomes in adulthood but little is known about the effects on adult parenting practices. This study aimed to examine prospective associations between adolescent conduct and emotional problems and subsequent parenting behaviours in adulthood. METHODS The study sample comprised 1110 members from the MRC Nationa...

BACKGROUND The 2011 Japan massive tsunami traumatized many children. The aim of this study was to assess changes in strengths and difficulties experienced in home and school by among surviving children after the 2011 tsunami, in comparison with published normal Japanese data. METHODS In November 2012 (20 months after the disaster) and September 2013 (30 months after the disaster), the Strengt...

Computational cost of metaheuristic based optimum design algorithms grows excessively with structure size. This results in computational inefficiency of modern metaheuristic algorithms in tackling optimum design problems of large scale structural systems. This paper attempts to provide a computationally efficient optimization tool for optimum design of large scale steel frame structures to AISC...

Implementation of evidence-based assessment and intervention approaches for youth with behavioral and/or emotional problems is rising to recognition worldwide. Feasibility research is critical to examine what characteristics of systems allow for success or barriers to the implementation of evidence-based practices into real-world settings, especially when working cross-culturally. This paper br...

This study investigated the construct validity of measures of teacher-student support in a sample of 709 ethnically diverse 2nd- and 3rd-grade academically at-risk students. Confirmatory factor analysis investigated the convergent and discriminant validities of teacher, child, and peer reports of teacher-student support and child conduct problems. Results supported the convergent and discrimina...

This meta-analytic review examines the association between attachment and internalizing symptomatology during childhood, and compares the strength of this association with that for externalizing symptomatology. Based on 42 independent samples (N = 4,614), the association between insecurity and internalizing symptoms was small, yet significant (d = 0.15, CI 0.06~0.25) and not moderated by assess...
