Research in Special Education: Implications for Practice

Identifying How to Better Support Parents of Children with Autism by Sarah Rushworth Autism Spectrum Disorder (ASD) is collection of neurological disorders affecting communication, social, and behavioral development (Nealy, 2012). More and more children are being diagnosed as having ASD each year in America. Today, 1 in every 110 children in the United States has autism (Nealy, 2012). The families of these children with autism must learn how to cope with the challenges that come along with the disorder. These challenges include lacking social and communication skills, which can lead to difficult behaviors. Raising a child with autism is associated with increased family stress and depression. This impacts family functioning and can lead to families being isolated from friends and family, as well as leave families with a feeling of stress and helplessness; parents need more support with how to cope with having a family member with autism in order to help improve these families overall quality of life (Russa, 2015). The purpose of this research was to examine how parents of children with autism could be better supported, using interview data. Families of children with autism need to have a variety of supports in place and overall feel as though they are not receiving enough (Nealy, 2012). The intention of this study is to obtain more knowledge of what parents of children with autism need in order to feel better supported, more confident, and less stressed. The Use of Project Based Learning to Empower Latino Students by Shannon Ward Today, the high school graduation rate for Latino males is 50% (Huerta, 2015). Additionally, Latino males often compose a disproportionate amount of suspensions, and the Latino population makes up a disproportionate amount of the students in special education. There has been much research done on the history of the Latino experience in the American school system, and how it has affected their current performance (Conchas, 2015), cultural factors that have impeded Latino student performance, as well as ways in which school counselors, and more developed college access programs can help mitigate this issue (Huerta, 2015). However, there has been little or no research done as to what teachers, in the classroom, can do to support Latino students to help them feel more part of the school community and graduate from high school. Therefore, the goal for this research is to identify learning strategies that can be successful in empowering Latino students in their education. The Common Core State Standards (CCSS) aim to provide young men and women with the skills necessary to be successful in their future college and career endeavors. The incorporation of Project Based Learning (PBL) is one method educators use to achieve this purpose. PBL may be very beneficial to the Latino community as its focus on group work will ensure that they interact with their peers, and become more involved in their own learning. Currently, there is significant research on PBL project ideas, group dynamics, and cooperative learning strategies. However, there is very limited empirical research on the effect PBL has on the education of struggling learners. Therefore, the goal of this study is to determine how to use PBL to empower students of the Latino community. Behavior Interventions for the Classroom by Anna Veelman Behavior challenges and Urban Education are two terms that unfortunately go hand and hand. Students from urban communities are more likely to experience trauma due to violence, death, neglect, and abuse. Children may respond to these traumatic experiences in the form of behaviors in the classroom. Students with trauma or behavior disorders are likely exhibit severe behaviors such as violence, disruption, self-harm, and defiance with in the classroom (Gregory, Skiba, & Noguera, 2010). Students who exhibit these types of behaviors may be put on a behavior plan or be referred for an Individualized Education Program for Emotional Disturbance or miss academics due to being sent out of the classroom. With a high amount of these students being boys of color, this increases the over-representation of this demographic within special education but also aids in the continuation of systems like the school to prison pipeline and achievement gap (Wilson, 2014). This project will be looking deeper into trauma-based behaviors and strategies for teachers to use within the classroom to best support students who exhibit these severe behaviors. The Role of Trauma in Special Education and Early Interventions for Educators by Kristen Wimpee Children\u27s brains develop within the context of their earliest environments and experiences. Their neural and social development can be affected as consequences of complex trauma, disorganized attachment, maltreatment, and abuse. During early childhood, children\u27s nervous systems are in their most vulnerable period of maturation and organizational development. Early life traumas and stresses can lead to structural and physiological differences, which can have long-term consequences on emotional, behavioral, cognitive, and social development. These students often have trouble interacting with others, communicating, playing, and learning. Research shows that students with trauma have difficulty with self-regulation and self-soothing; they tend to struggle with aggressive tendencies, attention, disassociation, and physical and motor delays (Bath, 2008). Children with adverse childhood experiences, including complex trauma, are more likely to be suspended, expelled, and have lower academic achievement. They are at a higher risk of failing, dropping out, and are usually assigned to special education. This puts students with early trauma histories at greater risk of behavioral challenges, suspension, expulsion, low academic achievement, drop out, and difficulty in peer relationships. Many of these children are assigned to special education. Early interventions and creating trauma- sensitive classrooms through multi-modal methods can significantly impact brain development for students who have experienced complex trauma by helping students to self-soothe and self-regulate. Therefore, this presentation will report on the complex link between trauma, diagnosed behavioral disabilities, and behavioral difficulties in the classroom that affect student learning. Trauma-informed teaching methods can help build strong relationships with trauma-affected children, who often have disrupted attachments. These methods can help students develop a resiliency mindset and develop the skills and motivation to successfully engage with the world around them

A biophysical model of prokaryotic diversity in geothermal hot springs

Recent field investigations of photosynthetic bacteria living in geothermal hot spring environments have revealed surprisingly complex ecosystems, with an unexpected level of genetic diversity. One case of particular interest involves the distribution along hot spring thermal gradients of genetically distinct bacterial strains that differ in their preferred temperatures for reproduction and photosynthesis. In such systems, a single variable, temperature, defines the relevant environmental variation. In spite of this, each region along the thermal gradient exhibits multiple strains of photosynthetic bacteria adapted to several distinct thermal optima, rather than the expected single thermal strain adapted to the local environmental temperature. Here we analyze microbiology data from several ecological studies to show that the thermal distribution field data exhibit several universal features independent of location and specific bacterial strain. These include the distribution of optimal temperatures of different thermal strains and the functional dependence of the net population density on temperature. Further, we present a simple population dynamics model of these systems that is highly constrained by biophysical data and by physical features of the environment. This model can explain in detail the observed diversity of different strains of the photosynthetic bacteria. It also reproduces the observed thermal population distributions, as well as certain features of population dynamics observed in laboratory studies of the same organisms

Variant Creutzfeldt-Jakob disease in the United Kingdom: a countrywide or local risk?

BACKGROUND: The aim of this study was to identify factors that may have augmented local risks for variant Creutzfeldt-Jakob disease (vCJD). METHODS: A descriptive study was conducted of local investigations of UK cases of vCJD, who had lived close together at some point since 1980. The main outcome measures were domestic, educational, occupational, healthcare associated, social and recreational links between cases; common dietary, iatrogenic and other possible routes of exposure to vCJD infection; and locally elevated vCJD risk. RESULTS: A cluster of five cases of vCJD in a rural area in North Leicestershire was investigated in 2000 (p=0.004). A further 12 investigations of geographically associated cases of vCJD have been undertaken in the UK. In nine of the 12 locations, some or all of the local cases had consumed beef purchased from the same local retail outlets or provided by a common supplier of school meals, or had some aspect of their medical-dental care in common. In only three of these locations were circumstances identified where the local risk of transmission might have been elevated. In none of the locations was there strong evidence to exclude chance as a likely explanation for the local occurrence of these vCJD cases. CONCLUSION: Although it is possible that in some parts of the UK local factors may have increased the risk of acquiring vCJD, most cases that were geographically close to each other are most likely due to the same factors that gave rise to the large majority of other vCJD cases in the UK

F., McKenna, A. M., Hansel, C. M., & Ward, C. P. Plastic formulation is an emerging control of its photochemical fate in the ocean. Environmental Science & Technology, 55(18), (2021): 12383–12392, https://doi.org/10.1021/acs.est.1c02272.Sunlight exposure is a control of long-term plastic fate in the environment that converts plastic into oxygenated products spanning the polymer, dissolved, and gas phases. However, our understanding of how plastic formulation influences the amount and composition of these photoproducts remains incomplete. Here, we characterized the initial formulations and resulting dissolved photoproducts of four single-use consumer polyethylene (PE) bags from major retailers and one pure PE film. Consumer PE bags contained 15–36% inorganic additives, primarily calcium carbonate (13–34%) and titanium dioxide (TiO2; 1–2%). Sunlight exposure consistently increased production of dissolved organic carbon (DOC) relative to leaching in the dark (3- to 80-fold). All consumer PE bags produced more DOC during sunlight exposure than the pure PE (1.2- to 2.0-fold). The DOC leached after sunlight exposure increasingly reflected the 13C and 14C isotopic composition of the plastic. Ultrahigh resolution Fourier transform ion cyclotron resonance mass spectrometry revealed that sunlight exposure substantially increased the number of DOC formulas detected (1.1- to 50-fold). TiO2-containing bags photochemically degraded into the most compositionally similar DOC, with 68–94% of photoproduced formulas in common with at least one other TiO2-containing bag. Conversely, only 28% of photoproduced formulas from the pure PE were detected in photoproduced DOC from the consumer PE. Overall, these findings suggest that plastic formulation, especially TiO2, plays a determining role in the amount and composition of DOC generated by sunlight. Consequently, studies on pure, unweathered polymers may not accurately represent the fates and impacts of the plastics entering the ocean.Funding was provided by the Seaver Institute, the Gerstner Family Foundation, Woods Hole Oceanographic Institution, and the National Science Foundation Graduate Research Fellowship Program (A.N.W.).

Doing gender locally: The importance of ‘place’ in understanding marginalised masculinities and young men’s transitions to ‘safe’ and successful futures

Observable anxieties have been developing about the position of boys and young men in contemporary society in recent years. This is expressed as a crisis of masculinity, in which place is often implicitly implicated, but is rarely considered for its role in the shaping of young men’s practices, trajectories and aspirations. Drawing on research conducted with young people who accessed a range of social care support services, this article argues that transition means different things for young men in different locales and that local definitions of masculinity are required to better understand young men’s lives and the opportunities available to them. The authors argue that home life, street life, individual neighbourhoods, regions and nations all shaped the young men’s identities and the practices they (and the staff working with them) drew on in order to create successful futures and ‘safe’ forms of masculinity. It is suggested that this place-based approach has the potential to re-shape the ‘crisis’ discourse surrounding masculinity and the anxieties associated with young men

Learning from the past and stepping into the future : toward a new generation of conflict prediction

Developing political forecasting models not only increases the ability of political scientists to inform public policy decisions, but is also relevant for scientific advancement. This article argues for and demonstrates the utility of creating forecasting models for predicting political conflicts in a diverse range of country settings. Apart from the benefit of making actual predictions, we argue that predictive heuristics are one gold standard of model development in the field of conflict studies. As such, they shed light on an array of important components of the political science literature on conflict dynamics. We develop and present conflict predictions that have been highly accurate for past and subsequent events, exhibiting few false-negative and false-positive categorizations. Our predictions are made at the monthly level for 6-month periods into the future, taking into account the social–spatial context of each individual country. The model has a high degree of accuracy in reproducing historical data measured monthly over the past 10 years and has approximately equal accuracy in making forecasts. Thus, forecasting in political science is increasingly accurate. At the same time, by providing a gold standard that separates model construction from model evaluation, we can defeat observational research designs and use true prediction as a way to evaluate theories. We suggest that progress in the modeling of conflict research depends on the use of prediction as a gold standard of heuristic evaluation

Computer simulation of pulsed field gel runs allows the quantitation of radiation-induced double-strand breaks in yeast

A procedure for the quantification of double-strand breaks in yeast is presented that utilizes pulsed field gel electrophoresis (PFGE) and a comparison of the observed DNA mass distribution in the gel lanes with calculated distributions. Calculation of profiles is performed as follows. If double-strand breaks are produced by sparsely ionizing radiation, one can assume that they are distributed randomly in the genome, and the resulting DNA mass distribution in molecular length can be predicted by means of a random breakage model. The input data for the computation of molecular length profiles are the breakage frequency per unit length, , as adjustable parameter, and the molecular lengths of the intact chromosomes. The obtained DNA mass distributions in molecular length must then be transformed into distributions of DNA mass in migration distance. This requires a calibration of molecular length vs. migration distance that is specific for the gel lane in question. The computed profiles are then folded with a Lorentz distribution with adjusted spread parameter to account for and broadening. The DNA profiles are calculated for different breakage frequencies and for different values of , and the parameters resulting in the best fit of the calculated to the observed profile are determined

Speech-language pathology services in Australian and New Zealand pediatric burn units and chemical ingestion injury

To date, little is known regarding the extent and nature of involvement of speech-language pathology (SLP) services within pediatric burn settings. The aim of this clinical service study was to investigate the role of SLP services within burn teams across Australia and New Zealand. Eleven pediatric burn units were identified as members of the Australian and New Zealand Burn Association Bi National Burns Registry. Representatives from both burn units and SLP departments at each setting were sent a link to a purpose-built online questionnaire. Seven responses from eight centers were received, with paired responses (burn units and SLP departments) being obtained from six centers. Pediatric burn units and SLP departments were found to differ in perceptions of SLP involvement in burn care. No burn units reported utilization of a protocol for referral to SLP. Dysphagia, followed by orofacial contracture management was the most frequently reported areas of SLP involvement, and multidisciplinary contribution within these areas was recognized. A majority (71%) of SLP departments reported involvement with chemical ingestion injury; however, referral rates were low. This study confirms that SLP services are utilized within Australian and New Zealand pediatric burn units, and SLPs are involved with pediatric patients with chemical ingestion injuries. However, potential exists for increased SLP input. There is also evident needed for established guidelines surrounding referrals and greater education regarding the role of SLPs within pediatric burn care

Divergent forms of pyroplastic: lessons learned from the M/V X-Press Pearl ship fire

The definitive version was published in James, B., de Vos, A., Aluwihare, L., Youngs, S., Ward, C., Nelson, R., Michel, A., Hahn, M., & Reddy, C. Divergent forms of pyroplastic: lessons learned from the M/V X-Press Pearl ship fire. ACS Environmental Au, 2(5), (2022): 467–479, https://doi.org/10.1021/acsenvironau.2c00020.In late May 2021, the M/V X-Press Pearl container ship caught fire while anchored 18 km off the coast of Colombo, Sri Lanka and spilled upward of 70 billion pieces of plastic or “nurdles” (∼1680 tons), littering the country’s coastline. Exposure to combustion, heat, chemicals, and petroleum products led to an apparent continuum of changes from no obvious effects to pieces consistent with previous reports of melted and burned plastic (pyroplastic) found on beaches. At the middle of this continuum, nurdles were discolored but appeared to retain their prefire morphology, resembling nurdles that had been weathered in the environment. We performed a detailed investigation of the physical and surface properties of discolored nurdles collected on a beach 5 days after the ship caught fire and within 24 h of their arrival onshore. The color was the most striking trait of the plastic: white for nurdles with minimal alteration from the accident, orange for nurdles containing antioxidant degradation products formed by exposure to heat, and gray for partially combusted nurdles. Our color analyses indicate that this fraction of the plastic released from the ship was not a continuum but instead diverged into distinct groups. Fire left the gray nurdles scorched, with entrained particles and pools of melted plastic, and covered in soot, representing partial pyroplastics, a new subtype of pyroplastic. Cross sections showed that the heat- and fire-induced changes were superficial, leaving the surfaces more hydrophilic but the interior relatively untouched. These results provide timely and actionable information to responders to reevaluate cleanup end points, monitor the recurrence of these spilled nurdles, gauge short- and long-term effects of the spilled nurdles to the local ecosystem, and manage the recovery of the spill. These findings underscore partially combusted plastic (pyroplastic) as a type of plastic pollution that has yet to be fully explored despite the frequency at which plastic is burned globally.This work was supported by the Postdoctoral Scholar Program at the Woods Hole Oceanographic Institution (WHOI), with funding provided by the Weston Howland Jr. Postdoctoral Scholarship.
