The Effects of IXL Practice on Geometry and Fraction Achievement

The purpose of this action research was to examine the effects of technology-based mathematics practice on student achievement in comparison to more traditional practice methods. The research took place in both a fourth-grade and a sixth-grade classroom in the same school. Technology-based practice was done using an iPad program called IXL and traditional practice was completed with paper and pencil on worksheets. Data was collected in the form of pretest and posttest scores, assignment completion rates, student behaviors, teacher reflections and student surveys. The data did not show any conclusive evidence that one practice method is better than the other. It is concluded that a combination of both practice methods may be most beneficial for student learning. After completing this research, a next possible step would be to further examine the influences on student learning based on grade level and mathematical concept when using technology and traditional practice methods.

Pretransplantation Assessments and Symptom Profiles: Predicting Transplantation-Related Toxicity and Improving Patient-Centered Outcomes

With the advent of reduced-intensity conditioning regimens and improvements in supportive care, hematopoietic cell transplantation (HCT) has become increasingly available to older adults and medically vulnerable populations with hematologic diseases. However, adverse outcomes including long-term treatment-related distress, disability (frailty), and death remain important concerns in this population. In other areas of oncology, comprehensive geriatric assessments have been used to stratify patients for treatment-related risk, and patient-reported outcomes (PROs) have helped in understanding treatment-related toxicity from a patient perspective. However, these powerful tools have not yet become widely used in HCT. Here, we review the theories and available data that support the development of pretreatment functional assessments and longitudinal PRO sampling in HCT. We discuss the potential for these techniques to improve transplantation outcomes through risk stratification, interventional studies, and predictive models that incorporate genetic and biomarker data. Predicting and understanding long-term transplantation-related toxicity through functional assessments and PROs will be critical to calculating the risk/benefit ratio of aggressive therapies in older patient populations, and we contend that functional assessments and PRO sampling should become standard parts of the routine evaluation of HCT patients

Actualizing hope and joy in K-12 curricula through Daisaku Ikeda’s human education

Purpose: Our study aims to create a framework grounded in Daisaku Ikeda’s philosophy of education for educators and researchers to implement and evaluate human education in the classroom. Research Methodology: We first synthesized the eighteen chapters by scholars involved in Ikeda studies, published in the book entitled: Hope and Joy in Education: Engaging Daisaku Ikeda across Curriculum and Context to discover the main themes in Ikeda’s human education. Based on these themes, we selected six children’s stories developed by Ikeda to design lessons. We then conducted surveys with ten K-12 teachers across disciplines and school districts to explore their perspectives toward humanity and their feedback on our lesson design. Results: Our finding indicates that creating hope and joy in education is inseparable from human revolution, value creation, happiness, the greater self, global citizens, as well as life and death. In addition, the participant’s responses to the survey questions help educators and researchers understand what K-12 teachers look for in order to implement lessons on humanity more efficiently and effectively. Limitations: By no means would we consider our lesson design exemplary or applicable in all different contexts. Instead, we consider these lessons a starting point to continue exploring a better way to teach humanity in school. Contribution: Seeing examples of lesson plans on humanity and learning from K-12 teachers’ perspectives provide an aspect for educators and researchers to use, extend, or expand the present study to bring hope and joy to students in their local contexts

An Ultra-Sparse Approximation of Kinetic Solutions to Spatially Homogeneous Flows of Non-continuum Gas

We consider a compact approximation of the kinetic velocity distribution function by a sum of isotropic Gaussian densities in the problem of spatially homogeneous relaxation. Derivatives of the macroscopic parameters of the approximating Gaussians are obtained as solutions to a linear least squares problem derived from the Boltzmann equation with full collision integral. Our model performs well for flows obtained by mixing upstream and downstream conditions of normal shock wave with Mach number 3. The model was applied to explore the process of approaching equilibrium in a spatially homogeneous flow of gas. Convergence of solutions with respect to the model parameters is studied. © 2019 The Author

The Health Status of Southern Children: A Neglected Regional Disparity

Purpose: Great variations exist in child health outcomes among states in the United States, with southern states consistently ranked among the lowest in the country. Investigation of the geographical distribution of children’s health status and the regional factors contributing to these outcomes has been neglected. We attempted to identify the degree to which region of residence may be linked to health outcomes for children with the specific aim of determining whether living in the southern region of the United States is adversely associated with children’s health status. Methods: A child health index (CHI) that ranked each state in the United States was computed by using statespecific composite scores generated from outcome measures for a number of indicators of child health. Five indicators for physical health were chosen (percent low birth weight infants, infant mortality rate, child death rate, teen death rate, and teen birth rates) based on their historic and routine use to define health outcomes in children. Indicators were calculated as rates or percentages. Standard scores were calculated for each state for each health indicator by subtracting the mean of the measures for all states from the observed measure for each state. Indicators related to social and economic status were considered to be variables that impact physical health, as opposed to indicators of physical health, and therefore were not used to generate the composite child health score. These variables were subsequently examined in this study as potential confounding variables. Mapping was used to redefine regional groupings of states, and parametric tests (2-sample t test, analysis of means, and analysis-of-variance F tests) were used to compare the means of the CHI scores for the regional groupings and test for statistical significance. Multiple regression analysis computed the relationship of region, social and economic indicators, and race to the CHI. Simple linear-regression analyses were used to assess the individual effect of each indicator. Results: A geographic region of contiguous states, characterized by their poor child health outcomes relative to other states and regions of the United States, exists within the “Deep South” (Mississippi, Louisiana, Arkansas, Tennessee, Alabama, Georgia, North Carolina, South Carolina, and Florida). This Deep-South region is statistically different in CHI scores from the US Census Bureau– defined grouping of states in the South. The mean of CHI scores for the Deep-South region was \u3e1 SD below the mean of CHI scores for all states. In contrast, the CHI score means for each of the other 3 regions were all above the overall mean of CHI scores for all states. Regression analysis showed that living in the Deep- South region is a stronger predictor of poor child health outcomes than other consistently collected and reported variables commonly used to predict children’s health. Conclusions: The findings of this study indicate that region of residence in the United States is statistically related to important measures of children’s health and may be among the most powerful predictors of child health outcomes and disparities. This clarification of the poorer health status of children living in the Deep South through spatial analysis is an essential first step for developing a better understanding of variations in the health of children. Similar to early epidemiology work linking geographic boundaries to disease, discovering the mechanisms/pathways/causes by which region influences health outcomes is a critical step in addressing disparities and inequities in child health and one that is an important and fertile area for future research. The reasons for these disparities may be complex and synergistically related to various economic, political, social, cultural, and perhaps even environmental (physical) factors in the region. This research will require the use and development of new approaches and applications of spatial analysis to develop insights into the societal, environmental, and historical determinants of child health that have been neglected in previous child health outcomes and policy research. The public policy implications of the findings in this study are substantial. Few, if any, policies identify these children as a high-risk group on the basis of their region of residence. A better understanding of the depth and breadth of disparities in health, education, and other social outcomes among and within regions of the United States is necessary for the generation of policies that enable policy makers to address and mitigate the factors that influence these disparities. Defining and clarifying the regional boundaries is also necessary to better inform public policy decisions related to resource allocation and the prevention and/or mitigation of the effects of region on child health. The identification of the Deep South as a clearly defined sub-region of the Census Bureau’s regional definition of the South suggests the need to use more culturally and socially relevant boundaries than the Census Bureau regions when analyzing regional data for policy development

Bridging the Divide White Paper on Medication Abortion: Overview of Research & Policy in the United States

Medication abortion (also called medical abortion) is a safe method of abortion available for the past 15 years in the US. The Bridging the Divide white paper summarizes the scientific evidence related to the current medication abortion process and potential changes to the process that could make it even safer and more accessible for patients, as well as policy considerations and directions for future research. In the fall of 2000, the US Food & Drug Administration (FDA) approved the drug Mifeprex© (generic: mifepristone) for use in medication abortions. That approval included requirements that affect both patients and providers and that are far more specific than typical requirements for prescription drugs. The package insert (also known as the product label) indicated procedures for mifepristone prescribers to follow, based on the regimen used during the drug’s pre-approval clinical trials. FDA has not approved any other abortion drugs besides Mifeprex. Fifteen years later, in March 2016, the FDA approved an updated label for Mifeprex, marking an important step forward for access to abortion care and for evidence-based policy. Although the new label is progress toward policy that is informed and driven by scientific research, the change came many years after research data had demonstrated the safety and efficacy of widely used evidence-based protocols. In the intervening years, some states took advantage of the outdated requirements in the product label and implemented restrictive policy measures that prevented their residents from accessing care based on the latest evidence and best practice. The Bridging the Divide white paper on the current state of medication abortion evidence and policy can be found below, along with a shorter summary document for policy-makers and a recently published commentary from the journal Women’s Health Issues
