The Impact Of Covid-19 On Autism Research: A Cross-Sectional Analysis Of Discontinued Or Suspended Clinical Trials, Monika Neale, Elizabeth Landers, Nicholas B. Sajjadi, Anya Mazur-Mosiewicz, Micah Hartwell

Student Publications

Due to uncertainties associated with the COVID-19 public health crisis, several clinical trials had to be withdrawn or postponed. Our investigation aimed to assess the rate of discontinuation of clinical trials focusing on Autism Spectrum Disorder. Of the 197 registered trials included in our systematic review, 15 (7.6%) were discontinued, with nearly half of these explicitly citing COVID-19 as their reason for discontinuation. Pharmacological trials were six times more likely to be discontinued during the pandemic than non-pharmacological studies. The difference between the likelihood of discontinuation was statistically significant (OR: 6.13; 95% CI: 1.22-30.71). There was no evidence of association …

The Effect Of Technology And Regulation On The Co-Evolution Of Product And Industry Architecture, Nicholas Burton, Peter Galvin

Research outputs 2022 to 2026

This paper explores the co-evolution of product and industry architecture by drawing on a longitudinal study of the UK personal pensions industry between 2005 and 2020. It provides qualitative evidence for the way in which institutional structures, particularly regulation, entwine with firm strategic choices to shape the contours of an industry value chain (IVC). We draw upon modularity theory and the literature on industry architecture to consider how strategic bottlenecks emerged and how value shifted between layers of the IVC. Furthermore, we examine the interplay between the agendas of the regulator and firm strategic responses to unpack how firms (product …

Ciało Obce: Zasady Rodo A Gospodarka Rynkowa, Przemysław Pałka

internetowy Kwartalnik Antymonopolowy i Regulacyjny (internet Quarterly on Antitrust and Regulation)

Artykuł analizuje relacje pomiędzy logiką RODO a logiką rynkową w kontekście tzw. kapitalizmu inwigilacji. Wbrew powszechnie przyjmowanej opinii szkody związane z komercyjnym nadzorem (manipulacja, dyskryminacja, negatywne skutki dla zdrowia psychicznego) często nie wynikają z niewystarczającej egzekucji RODO, a z faktu, że rozporządzenie to nie wypowiada się na temat legalności konkretnych celów przetwarzania danych. W realiach rynkowych, przy braku regulacji, to administratorzy de facto decydują o tym, jakie dane wykorzystane mogą być w jakim celu. By wyjść z tego impasu, artykuł proponuje ustawowe uregulowanie dopuszczalności niektórych konkretnych celów przetwarzania danych.

Sold Out! Ochrona Konsumentów Przed Wykupieniem Biletów Przez Środki Automatyczne, Konrad Rutkowski

internetowy Kwartalnik Antymonopolowy i Regulacyjny (internet Quarterly on Antitrust and Regulation)

Ticket scalping z wykorzystaniem środków automatycznych to praktyka polegająca na odsprzedaży biletów, które zostały wykupione ze stron internetowych przez boty (Porcello, 2018), czyli wyspecjalizowane oprogramowania. Wejściówki na wydarzenia są następnie sprzedawane zainteresowanym po zawyżonej cenie. Taka sytuacja stanowi zagrożenie dla konsumentów, którzy w ten sposób muszą wydać więcej pieniędzy. Wprowadzane zabezpieczenia cyfrowe często nie są odpowiednie, aby ochronić konsumentów przed środkami automatycznymi, ponieważ boty wykupują bilety ze strony internetowej w liczbie przekraczającej limity techniczne nałożone przez pierwotnego sprzedawcę. Ustawodawca unijny słusznie zwrócił uwagę, że należy zająć się problemem ticket scalpingu z wykorzystaniem środków automatycznych. Poza zbadaniem regulacji unijnej w artykule …

“I'M Not Batman” And Other Factors Impacting Bystander Intervention Against Sexual Violence In Australian Nightlife Settings, Aimee-Rose Wrightson-Hester, Alfred Allan, Maria M. Allan

Research outputs 2022 to 2026

Unsolicited sexual behaviors that constitute sexual violence appear to be commonplace in nightlife settings in many countries and bystander intervention might be a way to eliminate them. However, few researchers have investigated the barriers and facilitators that affect Australian bystanders’ likelihood to help, and these should be considered in the planning of bystander intervention programs. Using a grounded theory approach, we interviewed fourteen men and women about their perceptions of factors that might influence bystander behavior in Australian nightlife settings. The categories identified suggest that it is difficult for nightlife patrons to notice and identify sexual violence occurring around them. …

Lifetime Maximization In Underwater Wireless Communication Networks, Kazi Yasin Islam, Iftekhar Ahmad, Daryoush Habibi, Jiong Jin, Muhammad Waqas

Research outputs 2022 to 2026

The rise in demand for underwater wireless communication networks (UWCN) has been driven by the emergence of new applications including unmanned underwater vehicles, deep-sea exploration, maritime and underwater archaeology research, and diver communications. For various applications, underwater network lifetime must be long, since unlike terrestrial sensor networks, it is a major job to change/recharge node batteries in underwater environments. In this paper, we introduce a solution where critical nodes in a UWCN are periodically recharged by small renewable energy sources. Further, a caching mechanism is introduced to relieve critical nodes of heavy workload when their residual energies run low. By …

Throwing Stones In Glass Houses: Protecting Privacy Under The Law Of Nuisance, Cheng Lim Saw, Joon Wei Aaron Yoong

Research Collection Yong Pung How School Of Law

The limits of the law of nuisance were recently tested in the controversial decisions of Fearn v Tate Gallery Board of Trustees, both before the UK High Court and UK Court of Appeal. Against the backdrop of these decisions, this article argues that the tort of private nuisance can indeed, in appropriate cases, protect against invasions of privacy caused by overlooking – all within the present framework and ambit of the action. It is also proposed that a communitarian approach be adopted in fashioning the appropriate remedy for actions founded in nuisance.

BACKGROUND: Sickle cell disease (SCD) is a devastating, multisystemic disorder that affects millions of people worldwide. The earliest clinical manifestations of SCD can affect infants as young as 6 months of age, and pediatric patients are at risk for acute and life-threatening complications. Early intervention with treatments that target the underlying pathophysiological mechanism of SCD, sickle hemoglobin (HbS) polymerization, are expected to slow disease progression and circumvent disease-associated morbidity and mortality.

PROCEDURE: The HOPE-KIDS 1 trial (NCT02850406) is an ongoing four-part, phase 2a, open-label, single- and multiple-dose study to evaluate the pharmacokinetics, efficacy, and safety of voxelotor-a first-in-class HbS polymerization …

Receptor Tyrosine Kinase (Rtk) Targeting In Pediatric High-Grade Glioma And Diffuse Midline Glioma: Pre-Clinical Models And Precision Medicine., Kallen Schwark, Dana Messinger, Jessica R. Cummings, Joshua Bradin, Abed Kawakibi, Clarissa M. Babila, Samantha Lyons, Sunjong Ji, Rodrigo T. Cartaxo, Seongbae Kong, Evan Cantor, Carl Koschmann, Viveka Nand Yadav

Manuscripts, Articles, Book Chapters and Other Papers

Pediatric high-grade glioma (pHGG), including both diffuse midline glioma (DMG) and non-midline tumors, continues to be one of the deadliest oncologic diagnoses (both henceforth referred to as "pHGG"). Targeted therapy options aimed at key oncogenic receptor tyrosine kinase (RTK) drivers using small-molecule RTK inhibitors has been extensively studied, but the absence of proper in vivo modeling that recapitulate pHGG biology has historically been a research challenge. Thankfully, there have been many recent advances in animal modeling, including Cre-inducible transgenic models, as well as intra-uterine electroporation (IUE) models, which closely recapitulate the salient features of human pHGG tumors. Over 20% of …

A Tale Of Two Gentrifications: Reconceptualizing Gentrification Using Third Places, Demolition And Hierarchical Linear Modeling, Kylil R. Martin

Sociology & Criminal Justice Theses & Dissertations

A growing body of research points out that communities in the most need of assistance are often the ones established by racially biased processes and have not been invested in for generations – with little to no attention ever positively directed toward these spaces. Instead, because of policies and tactics used to label areas as problematic and divest from them, public actors are reluctant to consider the lived-lives, both good and bad, of the residents of these communities when discussing needed changes. Criminologists have long been interested in neighborhood change and its relationship with crime. There has also been theoretical …

Examining The Culturally Responsive Teaching Self-Efficacy Of Teacher Candidates In Urban Immersive Residency Programs, Latanya M. Sutphin

Teaching & Learning Theses & Dissertations

Urban immersive residency programs have emerged from partnerships between K-12 schools and universities offering teacher candidates a year-long field experience alongside coursework aligned with the framework and practices in the schools (Zeichner & Bier, 2015). The goals of these programs include teacher candidates applying what they learn during preparation into practice and getting good student outcomes, while building their confidence in teaching diverse students. This study used situated learning theory (Lave & Wenger, 1991) to position urban immersive residency programs as a community of practice where teacher candidate’s self-efficacy and understanding of culturally responsive teaching overlap. A mixed methods design …

Huber Kalman Filter For Wi-Fi Based Vehicle Driver's Respiration Detection, Yang Yang, Yunlong Luo, Alex Qi, Ge Shi, Miao Miao, Jun Fan, Jianhua Ma, Yihong Qi

Electrical and Computer Engineering Faculty Research & Creative Works

The use of breath detection in vehicles can reduce the number of vehicular accidents caused by drivers in poor physical condition. Prior studies of contactless respiration detection mainly targeted a static person. However, there are emerging applications to sense a driver, with emphasis on contactless methods. For example, being able to detect a driver's respiration while driving by using a vehicular Wi-Fi system can significantly enhance driving safety. The sensing system can be mounted on the back of the driver's seat, and it can sense the tiny chest displacement of the driver via Wi-Fi signals. The body displacement and car …

Application Of The Term Frequency-Inverse Document Frequency Weighting Scheme To The Pauline Corpus, Brandon Van Der Ventel, Richard Newman

Andrews University Seminary Studies (AUSS)

The term frequency--inverse document frequency (TF-IDF) weighting scheme is applied to the text of the thirteen epistles traditionally associated with the Apostle Paul. The data for the analysis is the morphologically tagged text of the Society for Biblical Literature’s Greek New Testament. The TF-IDF scheme is then used to construct the Document Term Matrix (DTM) for a corpus under consideration. The DTM allows each document to be represented by a multi-dimensional document vector. A query document is then chosen and a vector representation of it is constructed. The cosine similarity between the query document and documents in the corpus is …

Asian Medical Journal and Alternative Medicine

The high burden of kidney disease, global disparities in kidney care, and poor outcomes of kidney failure bring a concomitant growing burden to persons affected, their families, and carers, and the community at large. Health literacy isthe degree to which persons and organizations have or equitably enable individuals to have the ability to find, understand, and use information and services to make informed health-related decisions and actions for themselves and others. Rather than viewing health literacy as a patient deficit,
improving health literacy largely rests with health care providers communicating and educating effectively in codesigned partnership with those with kidney …

The Implication Of Digital Technologies And Interventions For Mental Health Care, Chommakorn Thanetnit

Asian Medical Journal and Alternative Medicine

The prevalence of mental health problems during the COVID-19 pandemic was higher than before. Physical distancing policies caused more difficulties in receiving traditional face-to-face mental health care, resulting in wider mental health treatment gaps. Regarding these barriers and the limitation of human resources, digital transformation in psychiatry has been widespread. This article summarized the recent supporting evidence of digital technologies and interventions in psychiatry, including telepsychiatry, computer-based and internet-based cognitive behavioral therapy, smartphone application-based intervention and virtual reality-based therapy, with the most studies for depressive disorders and anxiety disorders. The author also reviewed the usage of mental health chatbots, artificial …

Secure Retrieval Of Encrypted Similar Documents Using Bloom Filters, German Guzman

Theses, Dissertations and Culminating Projects

The ability to search for similar documents is a well-known problem on the Web and Information Retrieval field. For example, identifying similar profiles across different government agencies is an important process during intelligence gathering. Nonetheless, when data belongs to multiple parties, internal security policies and government regulations cannot allow the participating parties to freely share their sensitive documents. In our project, we aim to address the following problem: Given a user’s query Q and an encrypted database of documents stored on a third-party cloud server, we want to retrieve top-k documents similar to Q without disclosing Q and the contents …
