ABSTRACT
Although the importance of psychological well-being in early childhood is emphasized, the number of studies conducted with children and adolescents in this field is less than those carried out with adults. The present study aimed to explore the role of child emotion regulation in the relationship between parenting and psychological well-being among a sample of Turkish preschoolers aged 5-6. It further examines the mediating role of emotion regulation. The sample consisted of 416 mothers with children aged 5-6 (Mage = 5.38, SD = 0.48; 50% girls-boys). We collected the data using the Multidimensional Assessment of Parenting Scale (MAPS), the Emotion Regulation Checklist (ERC), and the Psychological Well-Being Scale for Children (PWBS-C). The findings revealed significant relationships among parenting practices (positive/negative), the child's emotion regulation/dysregulation, and the child's psychological well-being. Moreover, the findings revealed that positive parenting, directly and indirectly, affects children's psychological well-being through children's emotion regulation. On the other hand, findings disclosed that negative parenting has both a direct and indirect impact on children's psychological well-being through children's emotion regulation. Overall, the study may shed light on a possible process in which positive parenting boosts a child's emotional regulation and psychological well-being among preschoolers.
ABSTRACT
Although previous research demonstrated that greater mindfulness may contribute to life satisfaction, less is unclosed about such an association and the mechanisms potentially explaining it during adolescence. The present study aimed to explore the role of self-esteem and social competence in the mindfulness-life satisfaction relationship in a sample of Turkish adolescents. The sample consisted of 406 adolescents aged 14-18 years (Mage = 16.01, SD = 1.15; 62.32% girls). We collected the data using the Mindful Attention Awareness Scale-Adolescent (MAAS-A), the Perceived Competence Scale (PCS-S), the Rosenberg Self-Esteem Scale (RSES), and the Satisfaction with Life Scale (SWLS). The findings revealed significant positive correlations between mindfulness, social competence, self-esteem, and life satisfaction. Our findings support two ways of explaining this relationship: the mediating role of self-esteem (indirect effect = 0.04; 95% CI: 0.03-0.06), accounting for a total effect of 0.06 and a ratio of 66.67%, and the serial mediating role of social competence and self-esteem (indirect effect = 0.02; 95% CI: 0.01-0.03), accounting for a total effect of 0.06 and a ratio of 33.33%. In addition, the results of the multi-group analysis showed no significant difference between boys and girls in a model where mindfulness predicts life satisfaction. Overall, our study may shed light on a possible process in which mindfulness boosts life satisfaction among adolescents.
ABSTRACT
Colour removal from industrial effluents, particularly from the textile industry, has become an important requirement as the adverse effects ofdyestuffs, such as toxicity, on the environment have been proven. Adsorption is a commonly used treatment method for colour removal. Although activated carbon is very effective for this purpose, a number of natural materials and waste materials, such as waste sludges generated from treatment systems, have been tested to reduce the cost of the process. In this paper, sludges arising from the operation of an electrocoagulation process that used stainless steel or aluminium electrodes were investigated as adsorbents for decolorization of reactive dyestuffs. Electrocoagulation waste sludges produced with the use of stainless steel electrodes provided higher than 90% or complete decolorization of Crimson HEXL, Yellow HE4R and RB5 dyestuffs. The sludge produced with aluminium electrodes yielded colour adsorption between 95% and 100% at a 1 g/L dose and pH 8.5-9.1 for two of the dyestuffs; the removal of RB5 did not exceed 60% up to a 4.76 g/L dose. FeCl3 coagulation and adsorption using freshly precipitated coagulation sludge resulted in poor colour removals of 10% for all three dyestuffs. The superior colour adsorption performance of electrocoagulation waste sludges was attributed to modification of the surface properties of the sludges during the electrocoagulation operation. A batch-wise kinetic study indicated that the adsorption of RB5 on to electrocoagulation waste sludges was well fitted by the pseudo-second-order kinetic model, suggesting the intra-particle diffusion process as the rate-limiting step of the adsorption process.
