Socioemotional functioning across the transition to lower secondary school : The role of temperament and relationships with mothers and teachers

2023

This Finnish longitudinal study investigated the role of relationships with mothers (n = 631) and teachers (n = 56), and adolescents' (n = 848; 53.9% girls, 46.1% boys) temperament in the development of the adolescents' socioemotional functioning during the transition to lower secondary school (Grade 6 to Grade 7; age in Grade 6: M = 12.32, SD = 0.36). The results showed that mother–adolescent closeness predicted a higher level and teacher–adolescent closeness predicted a smaller decrease in prosocial behavior. Teacher–adolescent conflict predicted a higher level, and mother–adolescent conflict predicted an increase in externalizing problems. Only temperament predicted internalizing problem…

Longitudinal associations between adolescent behaviour problems and perceived family relationships

2010

AbstractThe goal of the present study was to examine the longitudinal associations between perceived family relationships and adolescents’ externalizing/ internalizing problems. The study sample included 366 pupils from secondary schools in Latvia, 12-14 years of age, who completed self-report questionnaires. Data were collected in two assessments 1 year apart. The results indicate that elevations in adolescent problem behavior prospectively predicted subsequent decreases in perceived family cohesion and increases in family conflict. The effect of perceived family cohesion and conflict as assessed at Time1 was not statistically significant in prediction of Time2 adolescent behaviour problem…

Social Work in the Area o Social Support for the Family with a Disabled Child

2013

In the times of continually changing socioeconamic conditions behind the functioning o f contemporary families, many of them have to cope with a variety of problems of everyday life. Families raising disabled children come to face a particularly hard situation in this respect, since problems pertaining to the emotional sphere, ones related to providing care and education, securing material and daily life needs, as well as those of the social nature, which appear within the families, are additionally augmented by the fact of their child’s disability. Solving the problems is often impossible relying on the limited resources of the family members themselves. And the support extended to them by…

Inverse problems and invisibility cloaking for FEM models and resistor networks

2013

In this paper we consider inverse problems for resistor networks and for models obtained via the finite element method (FEM) for the conductivity equation. These correspond to discrete versions of the inverse conductivity problem of Calderón. We characterize FEM models corresponding to a given triangulation of the domain that are equivalent to certain resistor networks, and apply the results to study nonuniqueness of the discrete inverse problem. It turns out that the degree of nonuniqueness for the discrete problem is larger than the one for the partial differential equation. We also study invisibility cloaking for FEM models, and show how an arbitrary body can be surrounded with a layer …

On the discreet spectrum of fractional quantum hydrogen atom in two dimensions

2019

We consider a fractional generalization of two-dimensional (2D) quantum-mechanical Kepler problem corresponding to 2D hydrogen atom. Our main finding is that the solution for discreet spectrum exists only for $\mu>1$ (more specifically $1 < \mu \leq 2$, where $\mu=2$ corresponds to "ordinary" 2D hydrogenic problem), where $\mu$ is the L\'evy index. We show also that in fractional 2D hydrogen atom, the orbital momentum degeneracy is lifted so that its energy starts to depend not only on principal quantum number $n$ but also on orbital $m$. To solve the spectral problem, we pass to the momentum representation, where we apply the variational method. This permits to obtain approximate analytica…

Economic Crisis, worker’s health and social protection

2023

Objective The aim of this paper is to analyse the individual and contextual factorsthat could affect worker’s mental and physical health during economic downturn.This paper fills the gap in the literature that addresses the link between crisis,physical and mental health.Methods Bivariate, machine learning method and multi-level regression analysiswere performed to explore the determinants of European Worker’s mental andphysical health. Machine learning method is dedicated to the predictors ofmental and physical health problems based on a classification algorithm,random forest model. Since the respondents of our data come from differentEuropean countries, the database has a hierarchical form…

Enseñanza de las ciencias : revista de investigación y experiencias didácticas

2021

Son frecuentes las aproximaciones cualitativas e intuitivas que se hacen en la escuela sobre el movimiento aparente del Sol por el firmamento que tratan de proporcionar al alumnado observaciones para que construya un modelo del sistema Sol-Tierra. El presente trabajo muestra la forma de obtener datos con mayor exactitud de manera que faciliten al alumnado una visión más amplia y profunda de dicho modelo, que lo capacite para enfrentarse y resolver problemas cotidianos y los pueda aplicar a diferentes contextos, como el cuestionamiento de situaciones sociales en las que interviene la luz solar. There are common the intuitive and qualitative approaches made in the School on the apparent movem…

INFORMATION QUALITY PROBLEMS ON WEBSITES

2019

The goal of this publication is to identify and characterize the typical problems with information quality on websites, and to present exemplary remedies for those problems. In this article the information quality problems within their origins, as well as the consequences of using poor-quality information by the Internet user were defined. There were also presented ways of improving information quality - which should facilitate the information needed by producers/authors and the managers/administrators of services in or to find solutions to the remaining problems. The presented varied remedies are not all possible solutions to improving quality in the area of the WWW content and its infrast…

Quantitative Runge Approximation and Inverse Problems

2017

In this short note we provide a quantitative version of the classical Runge approximation property for second order elliptic operators. This relies on quantitative unique continuation results and duality arguments. We show that these estimates are essentially optimal. As a model application we provide a new proof of the result from \cite{F07}, \cite{AK12} on stability for the Calder\'on problem with local data.
