An efficient method of addressing ectopic beats: new insight into data preprocessing of heart rate variability analysis

Heart rate variability (HRV) analysis is affected by ectopic beats. An efficient method was proposed to deal with the ectopic beats. The method was based on trend correlation of the heart timing signal. Predictor of R-R interval (RRI) value at ectopic beat time was constructed by the weight calculation and the slope estimation of preceding normal RRI. The type of ectopic beat was detected and replaced by the predictor of RRI. The performance of the simulated signal after ectopic correction was tested by the standard value using power spectrum density (PSD) estimation, whereas the results of clinical data with ectopic beats were compared with the adjacent ectopic-free data. The result showed the frequency indexes after ectopy corrected had less error than other methods with the test of simulated signal and clinical data. It indicated our method could improve the PSD estimation in HRV analysis. The method had advantages of high accuracy and real time properties to recover the sinus node modulation.

Supporting emotion regulation in individuals with ASD,ADHD and bipolar disorder through trauma-informed instruction and self-regulation strategies

Since the beginning of the COVID-19 pandemic, students have endured drastic changes in educational routines. Such disruptions can be especially challenging for students who struggle with executive functioning, self-regulation and emotion regulation, such as students with autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD) and bipolar disorder. Using a framework of trauma-informed instruction, the authors supported classroom teachers in implementing sensory spaces for students with ASD, ADHD and bipolar disorder. The project included professional development and funding for teachers to develop, procure and offer sensory tools and strategies to assist students in recognising and managing emotions. The authors collected data on the effectiveness of the sensory supports, combining teacher surveys and student behaviour data. Results indicated increased teacher knowledge on trauma-informed instruction and use of sensory supports to promote executive functioning and self-regulation and decreased target behaviours in students based on structured observation and anecdotal teacher feedback.     

Mapping the educational experiences of children with pathological demand avoidance

‘Pathological demand avoidance’ (PDA) describes a pattern of difficulties increasingly recognised as forming part of the autistic spectrum. Although clinical reports suggest that children with PDA are likely to experience considerable difficulties in education, their educational experiences have not yet been explored in any systematic way. In the current study, 42 parents of children with PDA completed a questionnaire about their child's educational experiences. Parents' responses indicated that this group of children displays high levels of problem behaviours in school, and receives corresponding high levels of special educational need support and professional involvement. Despite this support, the group had experienced high rates of exclusion and placement breakdown, with only 48% now in mainstream education. Parents reported relatively high satisfaction in their children's educational placements, with success defined by parents in terms of child outcomes, school characteristics and PDA‐specific factors. Findings are discussed with reference to what is known about the educational experiences of children with more typical autism spectrum conditions and in terms of the implications for the inclusion of this group of children with complex needs.

Creating the effective school : The role of evaluation

The concept of children's rights evolved during the 1980s giving prominence to the role of children as active participants in the construction of their lives. The rhetoric of children's rights has emerged as an important consideration in all policy and practice relating to children. Implementation of children's rights in practice is necessary to maximise their potential to improve the lives of children. This paper presents an argument for the importance of giving meaning to the implementation of children's rights in the Individual Education Plan (IEP) process for pupils with autistic spectrum disorder (ASD) in Ireland. The study, on which this paper is based, was conducted in two stages using both qualitative and quantitative approaches. The first stage focused on the development of a set of indicators for the IEP process based on a children's rights framework and informed by the perspectives of children, parents and teachers, alongside the literature on best practice on IEPs. In the second stage, a survey questionnaire was designed, based on the children's rights indicators, to evaluate current IEP practice in Ireland for pupils with autistic spectrum disorder. This article outlines the development of a set of indicators for the IEP process. It also presents findings of the survey which evaluates current practice in relation to the IEP process for pupils with ASD in Ireland. The article focuses specifically on Article 3(1) of the United Nations Convention on the Rights of the Child (UNCRC) which stipulates that in all actions concerning children, ‘the best interests of the child shall be a primary consideration’.
