The role of executive function in social competence and behavioral problems in the last year of preschool

Diverse studies have found a relationship between executive function, behavioral problems and social competence. However, until this moment, few studies have investigated the role of the distinct components of executive function in social competence, or in the most frequently encountered behavioral problems in childhood education. For this reason, the principal objective of this article is to evaluate the relation of the exec-utive functions with behavioral problems and social competence in infancy. The study included 260 students in their last year of preschool. The results of path analysis showed that all components of executive functions predict, at least, a behavioral problem. However, only deficits in flexibility and working memory predicted adaptability and social abilities. In conclusion, the results of the study showed that of the variables of executive function analyzed, it is deficits in inhibition that relate to the greatest number of behavioral problems; whilst cognitive flexibility is the variable which has the strongest relationship with adaptability and social skills.Diversos estudios han encontrado relaciones entre las funciones ejecutivas, los problemas de conducta y la competencia social. Sin embargo, hasta la fecha, hay pocos estudios que hayan investigado el papel de los distintos componentes ejecutivos en la competencia social y los problemas de conducta más frecuentes en Educación Infantil. Por esta razón, el principal objetivo de este artículo es analizar la relación entre las funciones ejecutivas, los problemas de conducta y la competencia social en la etapa infantil. En el estudio participaron 260 alumnos/as en su último año de Educación Infantil. Los resultados del path analysis mostraron que to-dos los componentes de las funciones ejecutivas predecían, al menos, un factor de los problemas de conducta. Sin embargo, solo los déficits en flexibilidad y en memoria de trabajo predijeron la adaptabilidad y las habilidades sociales. En conclusión, los resultados del estudio muestran que, de las variables de funciones ejecutivas analizadas, son los déficits en inhibición los que se relacionan con un mayor número de problemas de conducta, mientras que la flexibilidad cognitiva es la que tiene una relación más elevada con la adaptabilidad y las habilidades sociales.This study was carried out thanks to support for university teacher training from the Spanish Ministry of Education, Culture and Sport (FPU13/03470)

Heme Exporter FLVCR1a Regulates Heme Synthesis and Degradation and Controls Activity of Cytochromes P450

Background & AimsThe liver has one of the highest rates of heme synthesis of any organ. More than 50% of the heme synthesized in the liver is used for synthesis of P450 enzymes, which metabolize exogenous and endogenous compounds that include natural products, hormones, drugs, and carcinogens. Feline leukemia virus subgroup C cellular receptor 1a (FLVCR1a) is plasma membrane heme exporter that is ubiquitously expressed and controls intracellular heme content in hematopoietic lineages. We investigated the role of Flvcr1a in liver function in mice.MethodsWe created mice with conditional disruption of Mfsd7b, which encodes Flvcr1a, in hepatocytes (Flvcr1a fl/fl;alb-cre mice). Mice were analyzed under basal conditions, after phenylhydrazine-induced hemolysis, and after induction of cytochromes P450 synthesis. Livers were collected and analyzed by histologic, quantitative real-time polymerase chain reaction, and immunoblot analyses. Hepatic P450 enzymatic activities were measured.ResultsFlvcr1afl/fl;alb-cre mice accumulated heme and iron in liver despite up-regulation of heme oxygenase 1, ferroportin, and ferritins. Hepatic heme export activity of Flvcr1a was closely associated with heme biosynthesis, which is required to sustain cytochrome induction. Upon cytochromes P450 stimulation, Flvcr1afl/fl;alb-cre mice had reduced cytochrome activity, associated with accumulation of heme in hepatocytes. The expansion of the cytosolic heme pool in these mice was likely responsible for the early inhibition of heme synthesis and increased degradation of heme, which reduced expression and activity of cytochromes P450.ConclusionsIn livers of mice, Flvcr1a maintains a free heme pool that regulates heme synthesis and degradation as well as cytochromes P450 expression and activity. These findings have important implications for drug metabolism

Individual Differences in Adolescents’ Civic Engagement: The Role of Civic Discussions with Parents and Environmental Sensitivity

The main goal of the current study was to examine the direct and moderating effects of civic dis-cussions with parents and environmental sensitivity using both the total score and its specific di-mensions (i.e., Aesthetic Sensitivity, AES; Ease of Excitation, EOE; Low Sensitivity Threshold, LST) on youth civic engagement (attitudes and behaviours). The empirical analysis relied on a ques-tionnaire-based survey conducted on a sample of 438 adolescents (30% males), aged between 14 and 18 years (M = 16.50, SD = 1.36). We used a structural equation model (SEM) with latent vari-ables and the latent moderated structural equation (LMS) method to test our hypotheses. Our re-sults showed that civic discussions with parents were positively and significantly associated with general environmental sensitivity and with AES and predicted both civic attitudes and civic be-haviours; EOE was negatively and significantly related to civic behaviours; AES was positively and significantly related to civic attitudes; and LST was not significantly related to either civic attitudes or behaviours. Contrary to our expectations, environmental sensitivity did not moderate the rela-tionship between civic discussions with parents and civic engagement. Our study further high-lights the relevance that parents have in shaping their children’s civic engagement and makes a novel contribution regarding how differences in perceiving and processing environmental stimuli can affect beliefs and behaviours toward community issues among young individual

Using Focus Group in the Development of UNIPA Emotional Autonomy Inventory

Focus groups were used in order to develop a new measure of adolescents\u27 emotional autonomy from parents. The procedure started from an in depth analysis of the literature concerning the construct and a definition of the dimensions which characterize it. Following our idea of the construct, we developed a list of 60 items, getting some of them from existing instruments. Twenty-four adolescents participated in the focus group discussions about the adequacy of the items to measure emotional autonomy. Following their feedbacks a second version of the list with 59 items was presented in a focus group with experts in the field of developmental and clinical psychology, who were called to judge the ability of each item to evaluate the construct. Resulting from the indications emerged in this discussion, a final version of the scale with 66 items was developed and called UNIPA Adolescent Emotional Autonomy Inventory

Lactate Threshold Training Program on Patients with Multiple Sclerosis: A Multidisciplinary Approach

Physical activity could play a key role in improving the quality of life, particularly in patients with nervous system diseases such as multiple sclerosis (MS). Through lactacid anaerobic training, this study aims to investigate the effects at a bio-psycho-physical level to counteract the chronic fatigue associated with the pathology, and to improve mental health at a psychological and neurotrophic level. Eight subjects (age: 34.88 ± 4.45 years) affected by multiple sclerosis were involved. A lactate threshold training program was administered biweekly for 12 weeks at the beginning of the study (T0), at the end of the study (T1) and at 9 months after the end of the study (T2), with physical, psychological and hematochemicals parameters, and dietary habits being tested. The results obtained confirmed that lactacid exercise can influence brain-derived neurotrophic factor (BDNF) levels as well as dehydroepiandrosterone sulfate (DHEAS) levels. In addition, levels of baseline lactate, which could be best used as an energy substrate, showed a decrease after the protocol training. Self-efficacy regarding worries and concerns management significantly increased from T0 to T1. The eating attitudes test (EAT-26) did not highlight any eating disease in the patients with a normal diet enrolled in our study. Physical exercise also greatly influenced the patients psychologically and emotionally, increasing their self-esteem. Lactate threshold training, together with dietary habits, appears to exert synergic positive effects on inflammation, neural plasticity and neuroprotection, producing preventive effects on MS symptoms and progressio

Promoting Democratic and Intercultural Competences in the Primary School Context: The experience of “Children’s Voices for a new Human Space”

The promotion of citizen’s democratic and intercultural competence is one of the main actions that European societies may take against some of the most significant challenges they are facing nowadays. The paper is aimed at briefly describing the Council of Europe’s Reference Framework of Competences for Democratic Culture, some actions that can be taken to promote democratic and intercultural competences and a case of implementation of this framework in the context of primary school, that is the Erasmus+ Project “Children’s Voices for a new Human Space” (CVS). The paper also aims at illustrating the intellectual outputs produced by CVS project consisting in a training course for teachers, a curriculum for children, an app assisting trainers and teachers during the implementation of the training and the curriculum, and a scientific study aimed at investigating the efficacy of the educational processes in which teachers and children have been involved.

The role of late adolescents' emotion regulation in the experience of COVID-19 lockdown: A longitudinal study

The COVID-19 pandemic may be considered a unique mass-trauma experience. This study examined the relations between Italian late adolescents' emotion regulation strategies, their anxiety states, and their experience of the lockdown (in terms of discomfort related to restrictions, capacities to create new functional daily routines, and to find positive changes in one's own life) during the first wave of this pandemic. We analysed how participants' reports of cognitive reappraisal and expressive suppression were associated with anxiety states during the 2020 Italian COVID-19 lockdown (large scale physical distancing and movement restrictions) and one month after the lockdown restrictions had been removed. We also examined how cognitive reappraisal, expressive suppression, and anxiety states were linked to late adolescents' experience of lockdown. The participants were 497 Italian adolescents, aged from 17 to 24 years (Mage  = 21.11, SD = 1.83). A longitudinal structural equation modelling showed that emotion regulation strategies and anxiety states were not associated across time. Cognitive reappraisal was positively associated with routine reorganization and positive changes. In contrast, participants' expressive suppression was negatively related to their discomfort related to restrictions, ability to functionally reorganise their daily routine, and ability to find positive changes related to the COVID-19 emergency. Anxiety was positively linked to discomfort related to restrictions. The findings are discussed in light of the current literature related to emotion regulation and anxiety. Limitations and implications for practice are presented

Can we increase children’s rights endorsement and knowledge?: A pilot study based on the reference framework of competences for democratic culture

This pilot study is the first to examine whether a novel curriculum based on the Reference Framework of Competences for Democratic Culture (RFCDC) could increase children’s endorsement and knowledge of children’s rights. We conducted a pre-test-post-test design with an intervention and a comparison school. Pupils (n = 172) from Bulgaria, Italy, Norway, Romania, and Spain attended schools in which the curriculum was taught, whereas pupils in the comparison group (n = 120) attended schools in the same city where the curriculum was not taught. Both groups were tested on their endorsement and knowledge of rights before and at the end of the intervention. Children in the intervention group increased in endorsing children’s rights at post-test more than did children in the intervention group. Most children believed that children had rights. Children in the intervention group showed modest increases in their knowledge of rights. Future ways of implementing the RFCDC are suggested.publishedVersio
