Development of Internalizing Mental Health Symptoms from Early Childhood to Late Adolescence.

Children's mental health symptoms' development can be characterized by both continuity and discontinuity. However, existing studies ignore the potential discontinuity in children's internalizing symptoms' development. Hence, the current study examines continuous and discontinuous developmental trajectories using representative data from a sample of 2792 children (49.

Longitudinal relations between child emotional difficulties and parent-child closeness: a stability and malleability analysis using the STARTS model.

Background: Past empirical evidence on the longitudinal relations between emotional mental health symptoms and parent-child close relationships has produced mixed and inconclusive results. Some studies suggest a unidirectional relation, whereas other studies point toward a bidirectional association. Additionally, most of the past research has been carried out with adolescent samples, rather than children.

Dynamic interplay of developing internalising and externalising mental health from early childhood to mid-adolescence: Teasing apart trait, state, and cross-cohort effects.

The current study examined the within-child, between-child, and between-cohort effects in the longitudinal relations between and within the internalising and externalising mental health symptoms' domains. Leveraging the data of 5998 children (ages 4, 6, 8, 10, 12, 14 years; 49% female) from the sequential Growing Up in Australia dual-cohort, multigroup longitudinal measurement invariance, and random-intercept cross-lagged panel models were deployed. Multigroup longitudinal measurement invariance revealed that the measurements of peer problems, emotional symptoms, and hyperactivity were strictly invariant, whereas conduct problems were partially strictly invariant across cohorts over time.

Exploring age-related differences in metacognitive self-regulation: the influence of motivational factors in secondary school students.

Introduction: Metacognitive self-regulation is a crucial factor that promotes students' learning and achievement. However, the evidence regarding age differences in metacognitive skills is rather mixed, with some evidence pointing toward further refinement and development and other evidence suggesting declining levels. Academic motivation, an important antecedent of metacognitive self-regulation, has also been reported to decline steeply in adolescence.

Giant enhancement of nonreciprocity in gyrotropic heterostructures.

Nonreciprocity is a highly desirable feature in photonic media since it allows for control over the traveling electromagnetic waves, in a way that goes far beyond ordinary filtering. One of the most conventional ways to achieve nonreciprocity is via employing gyrotropic materials; however, their time-reversal-symmetry-breaking effects are very weak and, hence, large, bulky setups combined with very strong magnetic biases are required for technologically useful devices. In this work, artificial heterostructures are introduced to enhance the effective nonreciprocal behavior by reducing the contribution of the diagonal susceptibilities in the collective response; in this way, the off-diagonal ones, that are responsible for nonreciprocity, seem bigger.

Person-centred study on higher-order interactions between students' motivational beliefs and metacognitive self-regulation: Links with school language achievement.

Variable-centred studies assume that the links between motivation and metacognition with academic achievement are uniform across all students. However, this assumption may not hold and multiple interactions between motivational beliefs and metacognitive self-regulation may occur. To this end, the present study sought to explore these higher-order interactions and their links with school language achievement in a low-performance context.

Unraveling the complexity of the associations between students' science achievement, motivation, and teachers' feedback.

In recent decades, national science achievement in Greece is following a declining trend. A commonly held assumption is that achievement declines may occur either due to low quality teaching practices or due to students' low motivation. While motivational beliefs have been linked with achievement, there is not enough evidence connecting these motivational constructs with teachers' feedback, which can play an important role in nurturing both students' motivation and achievement.

Population heterogeneity in developmental trajectories of internalising and externalising mental health symptoms in childhood: differential effects of parenting styles.

Aims: Multiple studies have connected parenting styles to children's internalising and externalising mental health symptoms (MHS). However, it is not clear how different parenting styles are jointly influencing the development of children's MHS over the course of childhood. Hence, the differential effects of parenting style on population heterogeneity in the joint developmental trajectories of children's internalising and externalising MHS were examined.

Development of subjective well-being and its relationship with self-esteem in early adolescence.

Despite evidence indicating that self-esteem (SE) may be considered a precondition to subjective well-being (SWB), there are inconclusive findings regarding its developmental links with SWB. Considering the declines in SWB, the purpose of this study is to examine the developmental changes in SWB and its relationship with SE in early adolescence. The data of 11,231 adolescents aged 11 and 14 years old (50% females) from the Millennium Cohort Study were utilized.

Life satisfaction and mental health from age 17 to 21 years in a general population sample.

Adolescence is a period when both mental health (MH) and wellbeing start deteriorating, which raises the question of how the two phenomena are linked and whether deterioration in one might be used to flag problematic developments in the other. While research shows that wellbeing and MH are associated, the direction of the association is not clear and longitudinal analyses, that might help disentangle the cause and effect, are scarce. Moreover, few studies have investigated the directional relation between MH and wellbeing early in the life course.

Investigation of the Impact of School Climate and Teachers' Self-Efficacy on Job Satisfaction: A Cross-Cultural Approach.

The purpose of this study is twofold: (a) To confirm the mediating role of teachers' self-efficacy between the relation of school climate and teachers' job satisfaction and (b) to tease apart any cross-cultural effects of the association of self-efficacy and job satisfaction by comparing teachers' responses. Drawing upon the publicly available TALIS 2018 (June 2019) database, a representative sample of 51,782 primary school teachers from 15 countries was used for the analyses. Structural equation modeling was implemented to test for mediation effects of teachers' self-efficacy at the individuals' level and a general linear model (GLM) MANOVA was applied to compare the participants' scores in self-efficacy and job satisfaction across cultures.

Chiral Metamaterials with PT Symmetry and Beyond.

Optical systems with gain and loss that respect parity-time (PT) symmetry can have real eigenvalues despite their non-Hermitian character. Chiral systems impose circularly polarized waves which do not preserve their handedness under the combined space- and time-reversal operations and, as a result, seem to be incompatible with systems possessing PT symmetry. Nevertheless, in this work we show that in certain configurations, PT symmetric permittivity, permeability, and chirality is possible; in addition, real eigenvalues are maintained even if the chirality goes well beyond PT symmetry.

Breast cancer presenting as paraneoplastic erythroderma: an extremely rare case.

The skin may exhibit the first clinical evidence of a systemic disease and may provide the first clues to a diagnosis in malignancies. Erythroderma is defined as generalized redness and scaling and it is a clinical manifestation of a variety of underlying diseases including, rarely, solid tumors. Breast cancer is associated with a variety of skin paraneoplastic manifestations like acanthosis nigricans, erythromelalgia, thrombotic thrombocytopenic purpura, acrokeratosis paraneoplastica, dermatomyositis, systemic sclerosis, and scleroderma.
