La agresividad en la infancia: el estilo de crianza parental como factor relacionado

El presente estudio se propone analizar la posible relación existente entre la agresividad en los niños medida por sus padres a través del BASC (Sistema de Evaluación de la Conducta de Niños y Adolescentes) y el estilo de crianza según el PCRI (Cuestionario de Crianza Parental) compuesto por siete factores: apoyo, satisfacción con la crianza, compromiso, comunicación, disciplina, autonomía y distribución de rol, en una muestra de 338 niños (182 niños y 156 niñas) entre 3 y 14 años. Los resultados muestran la existencia de una relación significativa entre la agresividad en los niños y la mayoría de los factores del estilo de crianza parental. Además se establece un modelo capaz de predecir el 27% de la varianza con respecto a la agresividad en los niños, compuesto por la disciplina de ambos progenitores, el compromiso y la satisfacción con la crianza de los padres y la autonomía de las madres. Finalmente se discute la utilidad de estos resultados para el planteamiento de estrategias de intervención en el ámbito familiar basadas en el estilo disciplinarioThis current study proposes to analyse the possible relationship which exists between aggression in children reported by parents through the BASC (Behaviour Assessment System for Children), and the parenting style according to the PCRI (Parent-Child Relationship Inventory) composed of seven factors such as support, satisfaction with parenting, involvement, communication, limit setting, autonomy granting, and role orientation, in a sample of 338 children (182 male & 156 female) between 3 and 14 years old. The results show the existence of a significant relationship between aggression in children and the majority of the parenting factors. Furthermore, a model is established which is able to predict 27% of the variance with respect to aggression in children, made up by limit setting from both parents, involvement and satisfaction with parenting from the fathers, and autonomy granting from the mothers. Finally, the utility of results to raise intervention strategies within the family based on limit setting is discusse

Sintomas do assédio psicológico no ambito educativo

The present study tries to analyse the possible relationship between psychological harassment and determined psychosocial factors such as burnout, with its related factors of emotional tiredness, depersonalisation and personal fulfilment, type A behaviour pattern and its factors related to impatience, competitiveness, overload and hostility, psychological wellbeing in the work setting or general stress in social and work settings. Different standardised questionnaires were given to a sample of 220 teachers (93 males and 127 females) so that information could be collected about the aforementioned factors and other epidemiological data. The results revealed the existence of a significant relationship between psychological harassment and most predictive factors. A model able to predict 24.3% of variance regarding psychological harassment, consisting of variables regarding depersonalisation, hostility and stress was also establishedEl presente estudio se propone analizar la posible relación existente entre el acoso psicológico y determinados factores psicosociales como el burnout con sus factores cansancio emocional, despersonalización y realización personal, el patrón de conducta tipo A y sus factores impaciencia, competitividad, sobrecarga y hostilidad, el bienestar psicológico en el ambiente de trabajo o el estrés general en el ámbito socio – laboral. Con una muestra de 220 profesores (93 hombres y 127 mujeres) se recoge, mediante diversos cuestionarios estandarizados, información sobre los factores anteriormente descritos y otros datos de tipo epidemiológico. Los resultados muestran la existencia de una relación significativa entre el acoso psicológico y la mayoría de los factores predictores.

A Review about Parenting Style and Parenting Practices and Their Consequences in Disabled and Non Disabled Children

In order to explain the worst levels of adaptation showed by children with disabilities in relation to non disabled children, this paper aims to carry out a review of the most important advances achieved in recent decades in the study of parenting styles and parenting practices in relation to academic competence and behavior problems of children with and without disabilities. For this, we have carried out an analysis of the main works that show this relationship in the population, and then, we did the same including disability as a differentiating factor. In this sense, the authoritative style and specific parenting practices such as setting limits, communication, autonomy or monitoring are described as good predictors of adaptive behavior in children. However, we miss studies to confirm this relationship in children with disabilities. In this population, most of the papers refer, on the one hand, to expectations and, on the other hand, the stress in parenting and its effect on the parents’ mental health. In conclusion, the need to provide additional information about family relationships and disability is discusse

Paternal and Maternal Variables Related to Depression in Childhood

Several studies have highlighted the relationship between parenting styles and depression in children. The aim of this study is to ascertain whether there are differences in the parenting practices received by two groups of children who obtain low-risk and high-risk scores respectively in relation to depression and determine which parenting variables are linked with the presence or absence of this kind of internalizing problem. From a sample of 550 subjects, obtained by probabilistic cluster sampling, we selected 140 children between 3 and 12 years of age who met a set of specific criteria as having high risk scores (70 children) for depression according to the Behavior Assessment System for Children (BASC) or having low scores in this variable (70 children). Then, the Parent–Child Relationship Inventory (PCRI) was applied to both parents. We carried out a binomial logistic regression analysis which resulted in a prediction model for 89.3% of the sample, based on the following parenting variables: limit setting and involvement from the mothers, and parental support, autonomy, satisfaction with parenting, and communication from the fathers. Finally, the usefulness of our results to plan intervention strategies within families of children with depression is discussed

Relationship Between Parenting Style and Aggression in a Spanish Children Sample

The aim of this study is to ascertain whether there are any differences in the parenting style received by two groups of children who obtain low-risk and high-risk scores, respectively, in relation to aggressive behaviour and determine which parenting variables are linked with the presence or absence of this kind of problematic behaviour. We selected a sample of 33 children between 3 and 14 years old (21 male and 12 female) with risk scores in aggressive behaviour and another similar group with low scores in this variable. After administering both instruments to the parents, we carried out a binomial logistic regression analysis which resulted in a prediction model for the 87.9% of the sample, made up of the parenting variables: father‟s satisfaction with parenting and role orientation, and mother‟s autonomy and limit setting. Moreover, our analysis of the variance revealed significant differences in the support and communication perceived by the fathers and mothers of both groups. Lastly, the utility of results to propose intervention strategies within the family based on fathers involvement and an authoritative style is discussed

Pion and kaon electromagnetic and gravitational form factors

A unified set of predictions for pion and kaon elastic electromagnetic and gravitational form factors is obtained using a symmetry-preserving truncation of each relevant quantum field equation. A key part of the study is a description of salient aspects of the dressed graviton + quark vertices. The calculations reveal that each meson's mass radius is smaller than its charge radius, matching available empirical inferences; and meson core pressures are commensurate with those in neutron stars. The analysis described herein paves the way for a direct calculation of nucleon gravitational form factors.Comment: 12 pages, 4 figures, 3 table

The Trunk Appearance Perception Scale (TAPS): a new tool to evaluate subjective impression of trunk deformity in patients with idiopathic scoliosis

<p>Abstract</p> <p>Background</p> <p>Outcome assessment in idiopathic scoliosis should probably include patients' perception of their trunk deformity in addition to self-image. This can be accomplished with the Walter Reed Visual Assessment Scale (WRVAS). Nevertheless, this instrument has some shortcomings: the drawings are abstract and some figures do not relate to the corresponding radiological deformity. These considerations prompted us to design the Trunk Appearance Perception Scale (TAPS).</p> <p>Methods</p> <p>Patients with idiopathic scoliosis and no prior surgical treatment were included. Each patient completed the TAPS and SRS-22 questionnaire and underwent a complete radiographic study of the spine. The magnitude of the upper thoracic, main thoracic, and thoracolumbar/lumbar structural curves were recorded. The TAPS includes 3 sets of figures that depict the trunk from 3 viewpoints: looking toward the back, looking toward the head with the patient bending over and looking toward the front. Drawings are scored from 1 (greatest deformity) to 5 (smallest deformity), and a mean score is obtained.</p> <p>Results</p> <p>A total of 186 patients (86% females), with a mean age of 17.8 years participated. The mean of the largest curve (CMAX) was 40.2°. The median of TAPS sum score was 3.6. The floor effect was 1.6% and ceiling effect 3.8%. Cronbach's alpha coefficient was 0.89; the ICC for the mean sum score was 0.92. Correlation coefficient of the TAPS mean sum and CMAX was -0.55 (<it>P </it>< 0.01). Correlation coefficients between TAPS mean sum score and SRS-22 scales were all statistically significant, ranging from 0.45 to 0.52 (<it>P </it>< 0.05).</p> <p>Conclusions</p> <p>The TAPS is a valid instrument for evaluating the perception patients have of their trunk deformity. It shows excellent distribution of scores, internal consistency, and test-retest reliability, and has good capacity to differentiate the severity of the disease. It is simple and easy to complete and score, the figures are natural, and a new frontal view is included.</p

In this respect, this study proposes a new approach to improve the accuracy of the widely used five-parameter single-diode model. Two new physical equations are introduced to represent the series and shunt resistances, while the other parameters are represented by well established physical expressions. In the proposed model, most of the parameters are in terms of the cell temperature, irradiance, and datasheet values, while a few parameters need to be tuned. The model is compared with four well-known methodologies to extract the parameters of the single-diode and double-diode models. The simulation studies make use of the different I-V characteristics provided in the photovoltaics (PVs) datasheets, characteristics extracted from an outdoor module, as well as the ones simulated with the software PC1D. The results show an improved precision of the proposed model to estimate the power characteristics for a wide range of temperatures and irradiances, not only in the maximum power point but also in the whole range of voltages. Furthermore, the proposed physical model can be easily applied to other kind of studies where a physical meaning of the PV parameters is of great importance.Peer ReviewedPostprint (author's final draft
