Physiological reactivity to fear moderates the relation between parenting distress with conduct and prosocial behaviors

This study investigated whether the associations between parental distress with conduct problems (CPs) and prosocial behaviors (PBs) are moderated by children's skin conductance (SC) and heart rate (HR) reactivity to fear. Participants were 147 Greek-Cypriot children (M_age = 7.30, 44.2% girls), selected from a larger screening sample (data were collected from 2015 to 2018). Longitudinal associations suggested that children with high HR reactivity to fear were more likely to display PB, whereas those with low SC reactivity were more likely to engage in CP behaviors. In contrast, interaction effects suggested that children high on SC reactivity to fear were more susceptible to the effects of parental distress, as indicated by their higher vulnerability to engage in CP (cross-sectionally) behaviors and their lower scores on PB (cross-sectionally and longitudinally).     

Barriers to domestic violence education in Northern Ireland: Pupils' views and experiences

Domestic violence (DV) in adult and young people's intimate partner relationships is a social and public health problem across the globe. Education can play an important and unique role in addressing DV; however, it remains relatively under-investigated. The aim of this qualitative study set in Northern Ireland, the first of its kind, was to explore young people's views and experiences of DV education. Focus groups were conducted with 188 pupils (97 males and 91 females) aged 16 to 18 attending post-primary school. The data were analysed using thematic analysis and reveal five barriers to DV education: (1) absence of DV teaching and learning; (2) DV is a taboo topic; (3) lack of teacher training and expertise on DV; (4) religious influence; (5) prioritisation of academic achievement over pupil wellbeing. The results demonstrate that changes are needed in schools to improve the role of schools in addressing DV. From this qualitative study, we make recommendations for how school-based DV education may help prevent and protect young people against intimate partner violence.     

Relationship of executive functioning and memory to autism symptomology and adaptive functioning: Implications for reducing future underemployment

Understanding the relationship between executive functioning and its connection to working memory and adaptive functioning can inform planning and employment efforts. This study explored the relationship between memory and adaptive functioning with a sample of Autistic youths/young adults. Participant mean age was 21.3 (SD = 3.0). Of the 22 participants, 17 were male, and 19 white, non-Hispanic/Latina/o/x. All but one lived with their parent(s). Participants were administered a full battery assessing cognitive ability (WAIS-IV), memory and executive functioning (WMS-IV and DKEFS), autism symptomatology (ADOS-II), and adaptive functioning (SIB-R). A multivariate lasso regression model was used. Memory, especially as measured on the WMS-IV, was found to be significantly related to adaptive functioning and autism symptomatology. There appears to be continuing evidence that memory is highly related to adaptive functioning and autism symptomatology. Interventions involving auditory and immediate memory could be helpful in promoting more mutually effective social interactions necessary for positive employment outcomes.     

Instructional practices in secondary science: How teachers achieve local and standards-based success

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success.     

Robust stabilization of nonlinear time delay systems: A complete type functionals approach

The robust stabilization of some classes of nonlinear delay systems with nominal linear delay system is addressed. The form of the controller is not an a priori proposal, but it is the result of a synthesis relying on the use of complete type Lyapunov–Krasovskii functionals, leading to distributed delay linear or nonlinear robust control laws. Simulation results of the stabilization of a chemical refining process demonstrate the good performance of the proposed approaches.     

Strategic interactions in public R&D across European countries: A spatial econometric analysis

The paper adds to the existing literature on the determinants of government spending in Research and Development (R&D) by considering the role of strategic interactions among countries as one of the possible competing explanations, within a spatial econometric framework. We account for several factors affecting national levels of public R&D spending, including (i) the international context – i.e. Lisbon strategy; (ii) country characteristics – level of private R&D, GDP, trade openness and the National System of Innovation; (iii) countries’ similarities in relation to (a) trade and economic size and (b) sectoral specialization. The analysis is carried out on 14 European countries. First, we find that factors traditionally affecting the level of public R&D expenditure, such as the scale of the national economy, trade openness, sectoral specialization and private R&D, significantly influence the level of public R&D in European countries between 1994 and 2006. Interestingly, the introduction of the Lisbon strategy does not seem to have affected changes in the levels of public R&D spending. Second, by using different weight matrices, we confirm the existence of strategic interactions in relation to R&D spending among European countries with similar economic, international trade and sectoral structure characteristics, though not geographically close.
