Authentic Narratives Of Successful Pathways To Undergraduate Completion For Black Men, Tara M. Jones

Electronic Theses and Dissertations

This qualitative narrative study examined the authentic lived experiences of eight Black male participants who successfully completed their college undergraduate degree at a private college in the southeast United States. The participants were recruited via LinkedIn, a professional social media, networking site. It explored family, K-12, co-curricular, and community factors that contributed to the academic success of the participants throughout their educational journey. This study drew upon Harper’s (2012) antideficit theory framing the study from the lens of the positive aspects of their academic experiences rather than focusing on the negative aspects of Black men that graduate college at the …

'99-To-1’ Property Deals: Stamp Duty Avoidance Or Honest Mistake, Vincent Ooi

Research Collection Yong Pung How School Of Law

This article explains in detail the legal issues surrounding the recent ABSD audit and how exactly the general anti-avoidance rule and the stamp duty avoidance surcharge in the Stamp Duties Act 1929 can be invoked by the IRAS.The article highlights the fact that it may not be enough for a property buyer to show that the '99-to-1' holding was intended to enable the buyer to qualify for a home loan and not 'for stamp duty avoidance'. The property buyer must be able to answer the additional question of why the transfer of the property is 'staggered' in two stages and …

Shock Mobilities During Moments Of Acute Uncertainty, Biao Xiang, William L. Allen, Shahram Khosravi, Helene Neveu Kringelbach, Yasmin Y. Ortiga, Karen Anne S. Liao, Cuellar Jorge E., Lamea Momen, Priya Deshingkar, Mukta And Naik

Research Collection School of Social Sciences

The COVID-19 pandemic and interventions addressing it raise important questions about human mobility that have geopolitical implications. This forum uses mobility and immobility during the pandemic as lenses onto the ways that routinised state power reacts to acute uncertainties, as well as how these reactions impact politics and societies. Specifically, we propose the concept of "shock mobility" as migratory routines radically reconfigured: emergency flights from epicentres, mass repatriations, lockdowns, quarantines. Patterns of shock mobility and immobility are not new categories of movement, but rather are significant alterations to the timing, duration, intensity, and relations among existing movements. Many of these …

Public Cleanliness Satisfaction Survey 2022, Paulin Straughan, Mathews Mathew

Research Collection School of Social Sciences

The Singapore Management University undertook the fifth wave of the Public Cleanliness Satisfaction Survey (PCSS) with 2,020 Singapore residents providing responses to the survey from July to October 2022, amidst the COVID-19 pandemic.

The 2022 wave of the PCSS continued to reflect an overall satisfaction with public cleanliness in Singapore, similar to the last PCSS in 2021. Majority of survey respondents (92%) were satisfied with the cleanliness of public spaces that they had recently visited, with no change from 2021. Satisfaction with the cleanliness of food outlets saw the largest decrease (by 2.1%) among all location types, to 82.7%. Nevertheless, …

Continuous Implementation With Payoff Knowledge, Yi-Chun Chen, Takashi Kunimoto, Yifei Sun

Research Collection School Of Economics

The literature on robust mechanism design assumes players' knowledge about a fixed payoff environment and investigates global robustness of optimal mechanisms to large changes in the information structure. Acknowledging global robustness as a demanding requirement, we propose continuous implementation as a notion of local robustness. Keeping the assumption of payoff knowledge, we say that an SCF is continuously implementable if there exists a mechanism which yields the outcome close to the desired one for all types close to the planner's initial model. We show that when a generic correlation condition is imposed on the class of interdependent-value environments, any (interim) …

Liquidity Constraints, Consumption, And Debt Repayment: Evidence From Macroprudential Policy In Turkey, Sumit Agarwal, Muris Hadzic, Changcheng Song, Yildirim Yildiray

Research Collection Lee Kong Chian School Of Business

Using account-level credit card data from a large Turkish bank, we study the impact of a unique credit card policy that increases minimum payment on consumption and debt repayment. We show that the policy reduces credit card spending and debt, boosts existing debt repayment, and reduces credit card delinquency. The credit card debt of affected consumers falls on average by 50% two years into the policy’s implementation. An increase in minimum payment has a stronger effect than does a decrease of a similar magnitude. We build a benchmark life cycle model with soft liquidity constraint to explain the reduction in …

The Interstellar Scintillation Of Psr J1614-2230, Lekshmi Rajagopal

Theses

Observations of the millisecond pulsar J1614-2230 as part of the NANOGrav 12.5 yr dataset were utilised to study the scintillation and interstellar medium along the line of sight of PSR J1614-2230. Modelling noise signals in pulsar line of sight allows for isolation of the raw signal and therefore more precise pulse period measurements. These are extremely useful in Pulsar Timing Arrays and in their potential to be used as cosmic detectors for the gravitational wave background. J1614 presented clear, distinguishable intensity variations in a long observation taken in March 2014 by B.J.Shapiro-Albert et al. (2020), which provided motivation to further …

“People Like Me Get Left Out”: A Critique Of Feminist Movement Organizing Practices Through Access Audits Of Coalitional Spaces In Norfolk, Virginia, Megan Callahan-Palko

Institute for the Humanities Master's Papers, Projects, and Capstones

This capstone explores the exclusionary and ableist organizing and protest practices of social justice movements. Digital protest has become a solution to the problem of access, and has morphed into a sentencing of separation that is difficult to escape from. As such, how we protest and participate should be self-determined. Organizers should not assume that because a person has a disability they will be participating digitally, or from the confines of their homes. Equitable physical protest access is a disability justice issue that touches at the intersections of race, gender, class, and, of course, disability. Using intersectionality, black feminist thought, …

Deciding For Others: Local Public Good Contributions With Intermediaries, Andrej Angelovski, Praveen Kujal, Christos Mavridis

ESI Working Papers

Given the prevalence of local public goods, whose broader use is often limited by distance and borders, we propose a potential solution to the free-riding problem by having each participant/beneficiary delegate the public good contribution decision to a non-local intermediary who neither puts in own endowment into the public good nor benefits from it. Intermediaries make decisions under two compensation mechanisms where the incentives for the intermediary are either non-aligned (fixed) or aligned (variable) with those of the beneficiary. We find that the use of intermediaries, regardless of whether their compensation is aligned or not with that of the beneficiary, …

Vascular Mechanisms Of Rhabdomyolysis-Induced Acute Kidney Injury, Jeremiah Moyinolu Afolabi

Theses and Dissertations (ETD)

In patients with rhabdomyolysis, the overwhelming release of myoglobin into circulation is the primary cause of kidney injury. Myoglobin causes direct kidney injury as well as severe renal vasoconstriction. An increase in renal vascular resistance (RVR) results in renal blood flow (RBF) and glomerular filtration rate (GFR) reduction, tubular injury, and acute kidney injury (AKI). The mechanisms that underlie rhabdomyolysis-induced AKI are not fully understood but may involve the local production of vasoactive mediators in the kidney. Myoglobin stimulated endothelin-1 (ET-1) production in proximal tubular cells, an effect driven by NADPH oxidase-dependent oxyradical generation. Rats subjected to glycerol-induced rhabdomyolysis also …

Molecular And Cellular Investigations Of Prader-Willi Syndrome, Anna K. Victor

Theses and Dissertations (ETD)

Prader-Willi syndrome (PWS) is a complex multigenic neurodevelopmental disorder resulting in hypotonia, developmental delay, hypogonadism, sleep dysfunction and childhood onset obesity affecting 1 in 10,000 to 30,000 individuals. PWS is an imprinting disorder that is caused by a loss of expression of maternally imprinted genes in the 15q11.2-q13 region including NDN, MAGEL2, SNRPN/SNURF, and a cluster of snoRNAs. The majority of cases are caused by inheriting a paternal allele deletion of this region (65-75%) and a smaller number are caused by chromosome 15 maternal uniparental disomy (UPD) (20-30%) or imprinting center defects (1-3%). Here, we used dental pulp stem cells …

Modulation Of Cerebral Artery Smooth Muscle Bk Channel Function By Neurosteroids, Kelsey Caroline Cleland North

Theses and Dissertations (ETD)

Voltage-gated and Ca2+ activated K+ channels of large conductance (BK) channels are essential for many key physiological processes, such as controlling the contraction of smooth muscle, including cerebrovascular smooth muscle. Importantly, BK channels are made up of a homotetramer of α subunits which associate with accessory β subunits. These β subunits alter the activity of the channel; this modulation is subunit-specific. Moreover, these accessory subunits have tissue-specific expression, such that the β1 subunit is highly expressed within cerebrovascular smooth muscle and greatly increases the open probability of BK channels. Increased BK channel open probability is linked to increased dilation of …

Melanoma In A Patient With Dnmt3a Overgrowth Syndrome, David Y Chen, Leslie A Sutton, Sai Mukund Ramakrishnan, Eric J Duncavage, Sharon E Heath, Leigh A Compton, Christopher A Miller, Timothy J Ley

2020-Current year OA Pubs

Alterations in epigenetic regulators are increasingly recognized as early events in tumorigenesis; thus, patients with acquired or inherited variants in epigenetic regulators may be at increased risk for developing multiple types of cancer.

Myt1l Is Required For Suppressing Earlier Neuronal Development Programs In The Adult Mouse Brain, Jiayang Chen, Nicole A Fuhler, Kevin K Noguchi, Joseph D Dougherty

2020-Current year OA Pubs

In vitro studies indicate the neurodevelopmental disorder gene myelin transcription factor 1-like (MYT1L) suppresses non-neuronal lineage genes during fibroblast-to-neuron direct differentiation. However, MYT1L's molecular and cellular functions in the adult mammalian brain have not been fully characterized. Here, we found that MYT1L loss leads to up-regulated deep layer (DL) gene expression, corresponding to an increased ratio of DL/UL neurons in the adult mouse cortex. To define potential mechanisms, we conducted Cleavage Under Targets & Release Using Nuclease (CUT&RUN) to map MYT1L binding targets and epigenetic changes following MYT1L loss in mouse developing cortex and adult prefrontal cortex (PFC). We found …

Failure Of Early Mycological Clearance In Hiv-Negative Cryptococcal Meningitis, Zhihui Su, Chongliang Luo, Kai Dai, Dasen Yuan, Bang-E Qin, Meifeng Gu, Junyu Liu, Yong Chen, Fuhua Peng, Ying Jiang

2020-Current year OA Pubs

BACKGROUND: Negative cerebrospinal fluid (CSF) cultures at 2 weeks after antifungal treatment (early mycological clearance [EMC]) should be a treatment goal of cryptococcal meningitis (CM). However, EMC in human immunodeficiency virus (HIV)-negative patients with CM is poorly understood.

METHODS: We conducted a retrospective review of medical records and 1-year follow-up of 141 HIV-negative patients with CM with an initial positive CSF culture for

RESULTS: Of 141 patients, 28 (19.9%) had EMC failure. The 1-year mortality rate was 5.7% (8/141). Multivariate analysis showed that non-amphotericin B (AmB)-based regimens, baseline log

CONCLUSIONS: EMC failure in HIV-negative CM is attributed to non-AmB-based therapy …

Charged Multivesicular Body Protein 4b Forms Complexes With Gap Junction Proteins During Lens Fiber Cell Differentiation, Yuefang Zhou, Thomas M Bennett, Thomas W White, Alan Shiels

2020-Current year OA Pubs

Charged multivesicular body protein 4b (CHMP4B) is a core sub-unit of the endosomal sorting complex required for transport III (ESCRT-III) machinery that serves myriad remodeling and scission processes of biological membranes. Mutation of the human CHMP4B gene underlies rare forms of early-onset lens opacities or cataracts, and CHMP4B is required for lens growth and differentiation in mice. Here, we determine the sub-cellular distribution of CHMP4B in the lens and uncover a novel association with gap junction alpha-3 protein (GJA3) or connexin 46 (Cx46) and GJA8 or Cx50. Immunofluorescence confocal microscopy revealed that CHMP4B localized to cell membranes of elongated fiber …

Regulating Artificial Intelligence In International Investment Law, Mark Mclaughlin

Research Collection Yong Pung How School Of Law

The interaction between artificial intelligence (AI) and international investment treaties is an uncharted territory of international law. Concerns over the national security, safety, and privacy implications of AI are spurring regulators into action around the world. States have imposed restrictions on data transfer, utilised automated decision-making, mandated algorithmic transparency, and limited market access. This article explores the interaction between AI regulation and standards of investment protection. It is argued that the current framework provides an unpredictable legal environment in which to adjudicate the contested norms and ethics of AI. Treaties should be recalibrated to reinforce their anti-protectionist origins, embed human-centric …

Taxing Digital Platforms, Andrew Hayashi, Young Ran (Christine) Kim

Articles

The proliferation of digital services taxes (DSTs) in Europe is generally understood as a way for those countries to claim taxing rights over the profits of large digital platforms such as Google, Facebook, and Amazon. Under prevailing norms of international income taxation, these businesses had been able to avoid paying taxes in countries where they had no physical presence, even if they had many users in those countries. But the rise of big tech has generated a set of regulatory and political challenges, and tax is only one of these. The adoption of DSTs is not only about the fair …

The Commerciality Of Non-Profit Hospitals Requires Them To Be Taxed: Bringing The Debate To A Conclusion, Edward A. Zelinsky

Articles

It is now time to conclude our prolonged debate about the tax-exempt status of nonprofit hospitals. The contemporary nonprofit hospital is a commercial enterprise, materially indistinguishable for tax purposes from its profit-making, taxed competitor. The federal income tax and the states’ income, sales and property taxes should treat all hospitals alike, regardless of whether such hospitals are nonprofit or for-profit enterprises. In the interests of equity and efficiency, these similar institutions should be taxed similarly.

As a political matter, nonprofit hospitals will continue to defend their tax-exempt status. Like any other lucrative, vested interest, nonprofit hospitals will continue to fight …

Management’S Substantive Edges, Alexander A. Reinert

Articles

The article examines the evolution of judicial management in federal courts since Judith Resnik's seminal work, *Managerial Judges*, highlighting both advancements and persistent challenges. While increased transparency and the expanded role of magistrate judges have mitigated some concerns, issues like discovery disputes and the impact of the Prison Litigation Reform Act (PLRA) continue to shape judicial practice. The article critiques the disuniformity introduced by judges' individual standing orders, which, despite offering flexibility, raise concerns about procedural fairness, transparency, and consistency in federal procedure.

Aesthetics Of Slavery & Slave Trade Crimes, Jocelyn Getgen Kestenbaum

Articles

In his insightful new book, Invisible Atrocities, Randle DeFalco examines the aesthetic biases of international criminal law (ICL). DeFalco astutely argues that ICL prioritizes punishing "horrific spectacles" of violence while ignoring less visible, attritive forms of violence that cause similar levels of harm and suffering, generally over longer periods of time. While ICL is selective in its preference for "horrific spectacles," even the spectacular violence has been rendered invisible in ICL when inconvenient factual evidence counters dominant narratives in international law.

One such dominant narrative is the successful abolition of slavery and the slave trade of the nineteenth and twentieth …

Reproductive Health In America: A History Of Patriarchal Control, Hailey Mccool

Undergraduate Research Conference

The United States is often referred to as the land of opportunity and the home of the free, yet today, those who challenge the patriarchal system are not treated fairly or equitably. Historically, from owning land to voting women have fought for the same rights enjoyed by men. The effort of early feminist movements paved the way for the Supreme Court to protect women’s reproductive rights through Roe v. Wade. For decades, women were able to make a choice regarding their reproductive health. However, in just the past year (2022), the Supreme Court ruled to strike down Roe v. …

Foliar Expression Of Candidate Genes Involved In Condensed Tannin Biosynthesis In White Clover (Trifolium Repens), Stephen N. Panter, J. Simmonds, A. Winkworth, A. Mouradov, G. C. Spangenberg

IGC Proceedings (1977-2023)

Bloat disease in cattle and sheep is caused by the rapid microbial degradation of protein-rich fodder in the rumen. This leads to the production of protein foams that trap gases, causing bloat, a condition that is often fatal to livestock and costly to farmers. Condensed tannins (CTs) are phenolic polymers produced by the phenylpropanoid pathway of plants (Figure 1). CTs bind to proteins under acidic to neutral conditions, such as those present in the rumen, slowing their breakdown. A diet with a CT content of between 2% and 4% by dry weight, which is provided by some pasture legumes (e.g. …

Application Of Unmanned Aerial Vehicle–Based Infrared Images In Determining Characteristics Of Sea Surface Temperature Distribution, Hsing-Yu Wang, Hui-Ming Fang, Yun-Chih Chiang

Journal of Marine Science and Technology–Taiwan

This study investigated the temperature field of a body of water by using rotary-wing unmanned aerial vehicles (DJI Mavic 2 Enterprise Dual) comprising visible light and infrared cameras to determine sea temperature distribution. With a flight height of 150 m, image overlap of 80%, and image resolution of 4.75 cm/pixel, the proposed method was more effective than the conventional portable conductivity–temperature–depth device in rapidly measuring sea surface temperature and determining sea temperature distribution. The discharged heated water of the Hoping Power Plant traveled 100–330 m from the wastewater outfall and then gradually diffused in the range of 100–490 m before …

The Dark Side Of Leadership: Mid-Level Managers And Their Experience With Hubristic Behaviors Of Executives, Leili Sadaghiani

Dissertations
