Disgust,Need for Affect,and Responses to Microbiome Research

Contributing to the literature on affective processing and attitude formation, this study investigates the effects of a discrete emotion (disgust) and an emotional disposition (need for affect [NFA]) on support for regulation in the context of microbiome research. Data from a web-based experiment (N = 1,005) showed that experienced disgust mediated the effect of disgust-eliciting information on support for regulation. This mediated relationship was moderated by NFA. More specifically, NFA moderated the path between experienced disgust and regulatory attitudes but not that between message exposure and experienced disgust. The two dimensions of NFA played different moderating roles: Emotional approach amplified the relationship between disgust and the attitudinal outcome, whereas emotional avoidance attenuated it. The study furthers understanding about how NFA influences emotional processing and contributes to research on disgust as a relatively understudied discrete emotion.

Examination of the role of transient receptor potential vanilloid type 4 in endothelial responses to shear forces

Shear stress is the major mechanical force applied on vascular endothelial cells by blood flow, and is a crucial factor in normal vascular physiology and in the development of some vascular pathologies. The exact mechanisms of cellular mechano-transduction in mammalian cells and tissues have not yet been elucidated, but it is known that mechanically sensitive receptors and ion channels play a crucial role. This paper describes the use of a novel and efficient microfluidic device to study mechanically-sensitive receptors and ion channels in vitro, which has three independent channels from which recordings can be made and has a small surface area such that fewer cells are required than for conventional flow chambers. The contoured channels of the device enabled examination of a range of shear stresses in one field of view, which is not possible with parallel plate flow chambers and other previously used devices, where one level of flow-induced shear stress is produced per fixed flow-rate. We exposed bovine aortic endothelial cells to different levels of shear stress, and measured the resulting change in intracellular calcium levels ([Ca²⁺]_i) using the fluorescent calcium sensitive dye Fluo-4AM. Shear stress caused an elevation of [Ca²⁺]_i that was proportional to the level of shear experienced. The response was temperature dependant such that at lower temperatures more shear stress was required to elicit a given level of calcium signal and the magnitude of influx was reduced. We demonstrated that shear stress-induced elevations in [Ca²⁺]_i are largely due to calcium influx through the transient receptor potential vanilloid type 4 ion channel.     

A SYSTEMATIC FRAMEWORK FOR ADDRESSING TREATMENT INTEGRITY IN SCHOOL SETTINGS

School psychologists are tasked with ensuring treatment integrity because the level of intervention implementation affects decisions about student progress. Treatment integrity includes multiple dimensions that may impact the effectiveness of an intervention including adherence, dosage, quality, and engagement. Unfortunately, treatment integrity is not routinely monitored in consultation. A systematic framework is needed to better prepare practitioners to assess, analyze, and intervene when there are treatment integrity failures. A framework for monitoring and improving multiple dimensions of treatment integrity in natural settings is proposed to provide guidance to practitioners through two phases. The first phase focuses on improving initial treatment integrity and the second phase outlines a problem‐solving process for improving treatment integrity.     

Individual Differences in Emotional Reactivity and Academic Achievement: A Psychophysiological Study

Factors related to grade point average (GPA) are of great importance for students' success. Yet, little is known about the impact of individual differences in emotional reactivity on students' academic performance. We aimed to examine the emotional reactivity–GPA link and to assess whether self‐esteem and psychological distress moderate this relationship. Eighty undergraduate students reported on their GPA, self‐esteem, and psychological distress. Students' pupil radius was monitored during affective picture viewing to assess sympathetic activation in response to emotional stimuli. Cluster analysis on pupil reactivity to pictures identified low, average, and high emotionally reactive students. Regression analyses indicated that profiles of emotional reactivity were associated with GPA. This relationship was moderated by self‐esteem, but not psychological distress. Among students with higher emotional reactivity, those with lower self‐esteem reported poorer GPA. Findings document the importance of differences in students' emotional reactivity and self‐esteem in relation to academic success.     

A Methylome‐Wide Association Study of Trajectories of Oppositional Defiant Behaviors and Biological Overlap With Attention Deficit Hyperactivity Disorder

In 671 mother–child (49% male) pairs from an epidemiological birth cohort, we investigated (a) prospective associations between DNA methylation (at birth) and trajectories (ages 7–13) of oppositional defiant disorder (ODD), and the ODD subdimensions of irritable and headstrong; (b) common biological pathways, indexed by DNA methylation, between ODD trajectories and attention deficit hyperactivity disorder (ADHD); (c) genetic influence on DNA methylation; and (d) prenatal risk exposure associations. Methylome‐wide significant associations were identified for the ODD and headstrong, but not for irritable. Overlap analysis indicated biological correlates between ODD, headstrong, and ADHD. DNA methylation in ODD and headstrong was (to a degree) genetically influenced. DNA methylation associated with prenatal risk exposures of maternal anxiety (headstrong) and cigarette smoking (ODD and headstrong).     

Considerate,convivial and capacious? Finding a language to capture ethos in ‘creative’ schools

Concepts of school ‘ethos’ or ‘culture’ have been widely debated in education since the 1980s. This is partly as a consequence of marketisation, partly because ethos has been identified as a low-cost route to school improvement. Corporate, authoritarian, and most recently ‘military’ models of ethos have been widely promulgated in the UK. Another significant strand of educational thinking, however, has emphasised ethos for and as learning: how schools might prefigure alternative, more socially just, worlds. This article argues that accounting for such divergent notions of ethos demands greater attention to the intellectual resources mobilised in interpreting educational processes. We discuss schools that used their work with the English creative learning programme, Creative Partnerships, to develop what we describe as ‘considerate, convivial and capacious’ school ethos. We aim thereby to value their achievements, provide tools to contest dominant discourses around ethos, and advocate more critical, reflexive approaches to researching school cultures.     

Exploring the use of the ICT in supporting dyslexic students’ preferred learning styles : A preliminary evaluation

Dyslexia is one of the most common learning disabilities. It is described as a disorder manifested by difficulty in learning to read despite conventional instruction, adequate intelligence, and sociocultural opportunity. It affects relatively about 7–10 % of the population across most languages and cultures. In this study, we explore the potential benefits offered by the use of Information and Communication Technology (ICT) to support dyslexic students by considering their preferred learning styles. In the current paper we administered the VAK and Honey & Mumford questionnaires to 28 Arabic students with ages between 8 and 10 years old. 8 students from dyslexic group and 20 students from control group were selected to assess and compare their preferred learning style. The implemented system focuses on dyslexia in Arabic language, especially in Arabic countries such as Morocco. Based on the results of the analysis of learning styles differences, we introduced an adaptive mobile learning to support and promote learning for dyslexic students. The aim of the study is to consider the relationship between dyslexia and learning style and to suggest a different learning way. Preliminary results show that the ICT has a valuable role in providing opportunities for learners with dyslexia to participate more fully in education.
