4-H Senegal Community of Practice Developing STEM Curricula that Leads to Youth-driven Discovery and Innovation

In 2015, Jeunesse en Agriculture (JEA), French for “Youth in Agriculture” formed 4-H clubs in Senegal, West Africa. JEA set out to develop culturally relevant STEM curricula for their 4-H youth learners. This led to the novel formation of the 4-H Senegal STEM Community of Practice (CoP), a group designed to create engaging content and activities that leverage local interest and resources. The CoP Practice used a conceptual framework that applies the United States National Research Council’s Engage-Respond-Connect framing as criteria contextualized for 4-H Senegal STEM learning. JEA team members and the CoP used a design-based educational research approach to developing and testing new STEM curricula. The STEM curricula use the Do- Reflect- Apply model for learning through experience, along with scientific inquiry and engineering design as methodologies for youth learners to investigate and develop solutions on topics of their interest. This research note describes 4-H Senegal’s development of meaningful STEM content that enables youth-driven discovery and innovation

Synthesis of constrained robust feedback policies and model predictive control

In this work, we develop a method based on robust control techniques to synthesize robust time-varying state-feedback policies for finite, infinite, and receding horizon control problems subject to convex quadratic state and input constraints. To ensure constraint satisfaction of our policy, we employ (initial state)-to-peak gain techniques. Based on this idea, we formulate linear matrix inequality conditions, which are simultaneously convex in the parameters of an affine control policy, a Lyapunov function along the trajectory and multiplier variables for the uncertainties in a time-varying linear fractional transformation model. In our experiments this approach is less conservative than standard tube-based robust model predictive control methods.Comment: Extended version of a contribution to be submitted to the European Control Conference 202

Research on Teaching about Earth in the Context of Societal Problems

Knowledge and consideration of societal issues are critical for students majoring in the geosciences, as well as for non-science students and the general public who vote and make decisions that should be based on sound science. Thus, the importance of integrating geoscience with other disciplines such as urban planning, social justice, politics, communications and more has become a critical call to action for geoscience researchers and educators that merits examination. Improving undergraduate STEM education with the use of relevant issues such as societal problems is a useful mechanism to help students find science to be personally relevant and to develop their interest based on societal contexts (e.g., as is currently being done in the InTeGrate program). The grand challenges in this chapter examine the use of societal issues to teach about the Earth, which include consideration of the impact on student learning, the design principles of curricula that best integrate geoscience content within the context of societal issues, and the assessment needed to measure the efficacy of these methods

Depression and anxiety in parents of children with intellectual and developmental disabilities: A systematic review and meta-analysis.

INTRODUCTION: Although caring for a child with intellectual and developmental disabilities (IDD) can have positive outcomes, parents may be at a greater risk of depression and anxiety, due to a number of associated stressors, such as increased caregiver demands and financial strain. This systematic review updates previous data, exploring the relationship between parenting a child with IDD and parental depression and anxiety. METHODS: Five electronic databases were searched for eligible English-language articles, published between January 2004 and July 2018. All epidemiological study designs were eligible, provided the level of depression and/or anxiety was compared between parents of children (aged <18) with and without IDD. No limit was placed on geographic location. The proportion of positive associations between parenting a child with IDD and depression/anxiety were disaggregated by disability type, geographic region, and sample size. The percentage of parents at risk of moderate depression or anxiety were calculated using recognised clinical cut-off scores for each screening tool. Meta-analyses, in which pooled effect sizes of elevated depression and anxiety symptoms were calculated, were conducted across two IDD conditions, autism and cerebral palsy. RESULTS: Of the 5,839 unique records screened, 19 studies fulfilled the inclusion criteria. The majority of studies were conducted in high-income (n = 8, 42%) or upper-middle income countries (n = 10, 53%). Of the 19 studies, 69% focused on parents of children with cerebral palsy (n = 7, 37%) or autism (n = 6, 32%). Nearly all studies found a positive association between parenting a child with IDD and depression (n = 18, 95%) and anxiety (n = 9, 90%) symptoms. Factors associated with higher levels of depression symptoms amongst parents of children with IDD included disability severity (n = 8, 78%) and lower household income (n = 4, 80%). Approximately one third (31%) of parents of children with IDD reach the clinical cut-off score for moderate depression, compared with 7% of parents of children without IDD. 31% of parents of children with IDD reach the cut-off score for moderate anxiety, compared with 14% of parents of children without IDD. The meta-analyses demonstrated moderate effect sizes for elevated depression amongst parents of children with autism and cerebral palsy. CONCLUSIONS: Results indicate elevated levels of depressive symptoms amongst parents of children with IDD. Quality concerns amongst the existing literature support the need for further research, especially in low- and middle-income countries

Implementation of anaphylaxis management guidelines

Anaphylaxis management guidelines recommend the use of intramuscular adrenaline in severe reactions, complemented by antihistamines and corticoids; secondary prevention includes allergen avoidance and provision of self-applicable first aid drugs. Gaps between recommendations and their implementation have been reported, but only in confined settings. Hence, we analysed nation-wide data on the management of anaphylaxis, evaluating the implementation of guidelines. Within the anaphylaxis registry, allergy referral centres across Germany, Austria and Switzerland provided data on severe anaphylaxis cases. Based on patient records, details on reaction circumstances, diagnostic workup and treatment were collected via online questionnaire. Report of anaphylaxis through emergency physicians allowed for validation of registry data. 2114 severe anaphylaxis patients from 58 centres were included. 8% received adrenaline intravenously, 4% intramuscularly; 50% antihistamines, and 51% corticoids. Validation data indicated moderate underreporting of first aid drugs in the Registry. 20% received specific instructions at the time of the reaction; 81% were provided with prophylactic first aid drugs at any time. There is a distinct discrepancy between current anaphylaxis management guidelines and their implementation. To improve patient care, a revised approach for medical education and training on the management of severe anaphylaxis is warranted

Prevalence of depression, anxiety and post-traumatic stress disorder in health care workers during the COVID-19 pandemic: A systematic review and meta-analysis.

OBJECTIVE: The COVID-19 pandemic has placed health care workers under psychological stress. Previous reviews show a high prevalence of mental disorders among health care workers, but these need updating and inclusion of studies written in Chinese. The aim of this systematic review and meta-analysis was to provide updated prevalence estimates for depression, anxiety and post-traumatic stress disorder (PTSD) among health care workers during the COVID-19 pandemic, benefitting from the inclusion of studies published in Chinese. METHODS: Systematic search of EMBASE, MEDLINE, PsycINFO, Global Health, Web of Science, CINAHL, Google Scholar and the Chinese databases SinoMed, WanfangMed, CNKI and CQVIP, for studies conducted between December 2019 and August 2020 on the prevalence of depression, anxiety and PTSD in health care workers during the COVID-19 pandemic. Studies published in both English and Chinese were included. RESULTS: Data on the prevalence of moderate depression, anxiety and PTSD was pooled across 65 studies involving 97,333 health care workers across 21 countries. The pooled prevalence of depression was 21.7% (95% CI, 18.3%-25.2%), of anxiety 22.1% (95% CI, 18.2%-26.3%), and of PTSD 21.5% (95% CI, 10.5%-34.9%). Prevalence estimates are also provided for a mild classification of each disorder. Pooled prevalence estimates of depression and anxiety were highest in studies conducted in the Middle-East (34.6%; 28.9%). Subgroup and meta-regression analyses were conducted across covariates, including sampling method and outcome measure. CONCLUSIONS: This systematic review and meta-analysis has identified a high prevalence of moderate depression, anxiety and PTSD among health care workers during the COVID-19 pandemic. Appropriate support is urgently needed. The response would benefit from additional research on which interventions are effective at mitigating these risks

Aquatic Invasions: Causes, Consequences, And Solutions

Invasive species represent a global threat to ecosystems, human health, and the economy. A basic knowledge of invasive species biology is crucial to understand current and future impacts and implications. The purpose of this book is to provide a broad background on invasive species, and also details on specific examples through case studies. The students in the course Aquatic Invasive Species (MAR 442) at the University of New England in Biddeford, Maine, have researched and reviewed scientific literature to educate readers about these issues. The class, comprised of twelve junior and senior Marine Science, Marine Affairs, Applied Mathematics, and Environmental Sciences students, selected the different topics, presented the material, wrote the chapters, and assembled the final versions into this book. This book cannot be all inclusive, but we think this book will provide an excellent broad overview of the most important aspects of Invasive Species Biology and might stimulate the reader to dive deeper into the material.https://dune.une.edu/marinesci_studproj/1002/thumbnail.jp

Are Nepal's water, sanitation and hygiene and menstrual hygiene policies and supporting documents inclusive of disability? A policy analysis.

PURPOSE: This study assesses the inclusion of disability in Nepal's policy and guidance relevant to water, sanitation and hygiene (WASH), and menstrual hygiene management (MHM) in comparison to gender. We investigated both policy formulation and implementation, using the Kavrepalanchok district as a case study. MATERIALS AND METHODS: We used the EquiFrame framework, adapted for disability and gender, and focusing on WASH and MHM. Ten Nepali policies and guidance documents were reviewed and scored for quality against the framework, which included 21 core concepts of human rights. We also interviewed key informants to consider the inclusion of disability in the implementation of MHM interventions. We applied stratified purpose sampling to 12 government officials and service providers working in Kathmandu and the Kavrepalanchock district; conducted in-depth interviews and analysed data thematically using Nvivo 11. RESULTS: Disability was inadequately covered within the policy documents, and MHM policy commitments for disability were almost non-existent. Participation of people with disabilities in policy development was limited; within Kavrepalanchok, policy commitments were not implemented as intended and disability service providers were unable to allocate government resources. Inadequate data on disability and MHM resulted in limited professional understanding of the issues, as service providers had no training. A narrow WASH infrastructure approach to improving MHM for people with disabilities was prioritised. MHM interventions were delivered in schools; these failed to reach children with disabilities who are often out of school. Finally, there were indications that some caregivers seek sterilisation for people with disabilities who are unable to manage menstruation independently. CONCLUSION: Though the Constitution of Nepal enshrines gender equality and disability inclusion, there are consistent gaps in attention to disability and MHM in policies and practice. These omit and exclude people with disabilities from MHM interventions. Investment is required to generate evidence on the MHM barriers faced by people with disabilities, which would then be drawn on to develop training on these issues for professionals to improve understanding. Subsequently, policy makers could include more concepts of human rights against disability in relevant policies and service providers could implement policy commitments as intended

Mobile assistive technologies for the visually impaired

There are around 285 million visually impaired people worldwide, and around 370,000 people are registered as blind or partially sighted in the UK. Ongoing advances in information technology (IT) are increasing the scope for IT-based mobile assistive technologies to facilitate the independence, safety, and improved quality of life of the visually impaired. Research is being directed at making mobile phones and other handheld devices accessible via our haptic (touch) and audio sensory channels. We review research and innovation within the field of mobile assistive technology for the visually impaired and, in so doing, highlight the need for successful collaboration between clinical expertise, computer science, and domain users to realize fully the potential benefits of such technologies. We initially reflect on research that has been conducted to make mobile phones more accessible to people with vision loss. We then discuss innovative assistive applications designed for the visually impaired that are either delivered via mainstream devices and can be used while in motion (e.g., mobile phones) or are embedded within an environment that may be in motion (e.g., public transport) or within which the user may be in motion (e.g., smart homes)
