    Eradicating Race-Based Health Disparities by Effectuating the Fair Housing Act\u27s De-Segregation Intent

    This Article illustrates how Congress did not adopt this anti-segregation legislation in a vacuum. Rather, as the Supreme Court recently acknowledged, the FHA was a response to racial segregation. Congress enacted the legislation days after Dr. Martin Luther King Jr.’s assassination and on the heels of the Kerner Commission’s report, which identified segregation as the cause of unprecedented nationwide civil unrest. Part II of this Article demonstrates how housing is a major determinant of health, identifies the extent to which our nation is segregated, and illustrates how segregation exacerbates health inequities among racial and ethnic lines. Part III presents the historical landscape during which the FHA was adopted to demonstrate its primary purpose of dismantling segregation, by detailing the Kerner Commission, housing justice work spearheaded by Dr. King before his assassination, and the Supreme Court’s early FHA decisions. Part IV sets forth the FHA’s statutory framework and presents the perpetuation-of-segregation theory of disparate-impact liability, focusing on claims against government entities. This Article concludes by arguing the time is ripe for this nation to wage a war on segregation. Such an effort is not only possible within the current legal landscape, but also necessary to effectuate the FHA’s purpose at a time when the nation is at risk of deepening segregation and widening disparities due to the COVID-19 public health crisis

    Catalytic polymerization of dialkyl-, alkylaryl- or diaryldiethynylhydridosilanes cleanly affords soluble poly(silylene)vinylenes which can be shaped as fibers, films and bulk objects and thermally converted to silicon carbide

    Low temperature joining of ceramic composites

    Get PDF
    A method of joining similar or dissimilar ceramic and ceramic composite materials, such as SiC continuous fiber ceramic composites, at relatively low joining temperatures uses a solventless, three component bonding agent effective to promote mechanical bond toughness and elevated temperature strength to operating temperatures of approximately 1200 degrees C. The bonding agent comprises a preceramic precursor, an aluminum bearing powder, such as aluminum alloy powder, and mixtures of aluminum metal or alloy powders with another powder, and and boron powder in selected proportions. The bonding agent is disposed as an interlayer between similar or dissimilar ceramic or cermaic composite materials to be joined and is heated in ambient air or inert atmosphere to a temperature not exceeding about 1200 degrees C. to form a strong and tough bond joint between the materials. The bond joint produced is characterized by a composite joint microstructure having relatively soft, compliant aluminum bearing particulate regions dispersed in a ceramic matrix

    Implementing depression care in under-resourced communities: a school-based family resilience skill-building pilot randomized controlled trial in the United States

    IntroductionYouth in under-resourced communities are more likely to have greater social risk factors for mental health needs yet have less access to needed care. School-based mental health services are effective in treating common disorders such as adolescent depression; however, few have a family-centered approach, which may especially benefit specific populations.MethodsUtilizing a community-partnered approach, we adapted an established, trauma-informed, resilience skill-building family intervention for adolescents with depression. We conducted a small randomized controlled feasibility pilot of an adapted intervention in a large school district that serves predominately low-income, Latinx students in the Southwest United States between 2014-2017. Youth between the ages of 12-18 years old with a Patient Health Questionnaire (PHQ-8) score of 10 or higher, who spoke English or Spanish, were recruited from 12 school mental health clinics. Twenty-five eligible adolescents with depression and their participating caregivers were enrolled and randomly assigned to receive either the adapted intervention, Families OverComing Under Stress for Families with Adolescent Depression (FOCUS-AD), or usual care, Cognitive Behavioral Therapy (CBT) only. Most of the sample was Latinx and female. We evaluated feasibility, acceptability, and preliminary effectiveness.ResultsAmong participants who completed standardized assessments administered at baseline and approximately five months post-randomization (n = 10 FOCUS-AD, n = 11 CBT only), effectiveness was explored by identifying significant changes over time in adolescent mental health within the FOCUS-AD and CBT only groups and comparing the magnitude of these changes between groups. Nonparametric statistical tests were used. We found the FOCUS-AD intervention to be feasible and acceptable; participant retention was high. Adolescent symptoms of depression (measured by the PHQ-8) improved significantly from baseline to follow-up for youth in both FOCUS-AD (median decrease [MD] = 10, p = 0.02) and control (MD = 6, p = 0.01) groups, with no significant difference across the two groups. Results were similar for symptoms of PTSD (measured by the Child PTSD Symptom Scale; FOCUS-AD MD = 12.5, p = 0.01; CBT only MD = 7, p = 0.04; no significant difference between groups).ConclusionFamily-centered approaches to depression treatment among adolescents living in under-resourced communities may lead to improved mental health, although further research is warranted

    Hybrid dissolved-oxygen and temperature sensing: a nanophotonic probe for real-time monitoring of chlorella algae

    Get PDF
    Dissolved-oxygen concentration and temperature are amongst the crucial parameters required for the precise monitoring of biological and biomedical systems. A novel hybrid nanocomposite probe for real-time and contactless measurement of both dissolved-oxygen concentration and temperature, based on a combination of downconverting phosphorescent molecules of platinum octaethylporphyrin and lanthanide-doped upconverting nanoparticles immobilized in a host of polystyrene, is here introduced. Chlorella algae are employed here as a model to demonstrate the hybrid nanophotonic sensor’s capability to monitor the aforementioned two parameters during the photosynthesis process, since these are among the parameters impacting their production efficiency. These algae have attracted tremendous interest due to their potential to be used for diverse applications such as biofuel production; however, feasibility studies on their economic production are still underway

    Exploring indicators of circular economy adoption framework through a hybrid decision support approach

    Get PDF
    Circular economy (CE) focuses on a circular approach to energy and material resources, which provides economic, environmental and social benefits for manufacturing organisations. CE adoption in emerging economies facilitates in substantial economic growth through appropriate utilisation of energy and material resources across manufacturing industries. This study identifies CE indicators in the context of an emerging economy. The study further develops a framework for the adoption of CE and tests it through a hybrid Best Worst Method and Decision-Making Trial and Evaluation Laboratory approach. The framework is validated through an Indian manufacturing case organisation. While Best Worst Method computes the CE related indicator weights, Decision-Making Trial and Evaluation Laboratory analyses the inter-relationship among indicators. Disparate CE related indicators, e.g. strategic, managerial, informational and technological, supply chain and organisational, influence the CE adoption in an emerging economy context. The findings reveal that the strategic and managerial indicators have the strongest influence on developing other indicators. The causal digraph and relationship diagram assist the practitioners in predicting the inter-relationship of indicators in CE adoption. The study outcomes will help the practitioners, policymakers and researchers to draw a framework for adoption of circular and green practices and usage of resources sustainably
