An Empirical Analysis Of Pricing And Payments In The Pharmaceutical Industry, Rahul Narnindi

Dissertations and Theses Collection (Open Access)

High prescription drug prices in the US are a major hurdle on the road to improved public health. On a per-capita basis, US prescription drug spending is more than twice that of comparable OECD peer nations and yet the health outcomes achieved are worse. Policymakers try to implement countermeasures, such as the Inflation Reduction Act of 2022, to reduce the burden on the public but these countermeasures may result in unintended consequences. In this thesis, I study the effectiveness of two of these countermeasures and their unintended consequences. My first essay investigates prescription (Rx) to over the counter (OTC) drug …


How Do Firms Respond To Reduced Private Equity Buyout Activity?, Yi-Hsin Lo Mar 2025

How Do Firms Respond To Reduced Private Equity Buyout Activity?, Yi-Hsin Lo

Dissertations and Theses Collection (Open Access)

I investigate how firms respond to reduced private equity buyout activity in their home states by exploiting the state-by-state adoption of laws that increase the cost of buyouts. I find evidence suggestive of reduced firm efficiency. The firms also become less likely to go bankrupt or to relocate to other states. These findings suggest that the firms' managers may be starting to enjoy the quiet life. I also find a reduction in layoffs. Overall, the results indicate a trade-off: Whereas reduced private equity buyout activity increases managerial entrenchment, it also lowers firm exits and strengthens employees' job security.

Low-dose aspirin is recommended for prevention of hypertensive disorders of pregnancy (HDP) and preterm birth (PTB) in high-risk pregnancies. There is limited data on factors impacting aspirin response in pregnancy. We aimed to evaluate predictors of aspirin response and association with pregnancy outcome with a prospective study of high-risk pregnancies taking 81 mg aspirin daily. Aspirin response was evaluated with Platelet Function Assay-100 (PFA-100) epinephrine closure time at baseline (< 16 weeks' gestation), follow-up 1 (2-4 weeks after aspirin initiation), and follow-up 2 (28-32 weeks gestation). Multivariable regression was used to identify factors associated with PFA-100 at each visit, and results presented with beta coefficient (B) and confidence interval. The median difference (MD) in PFA-100 in those with and without HDP or PTB was compared. Results included 108 who completed follow-up 1 and 96 who completed both visits with > 75% adherence. PFA-100 was increased from baseline at follow-ups 1 and 2 (MD 37 (27-49); MD 26 (15.5-38.5) respectively). At follow-up 1, obesity (B = -30 (-53 to -7) seconds), …

Lawyering As A Public Health Tool: Enforcing Title Ii Of The Americans With Disabilities Act With Preventative Litigation, Elena Cohen Mar 2025

Lawyering As A Public Health Tool: Enforcing Title Ii Of The Americans With Disabilities Act With Preventative Litigation, Elena Cohen

Fordham Law Review

A recent ruling by the U.S. Court of Appeals for the Fifth Circuit held that plaintiffs cannot bring a claim alleging a risk of unnecessary institutionalization under Title II of the Americans with Disabilities Act (ADA). This directly contradicts the holdings of six other circuit courts and guidance issued by the Department of Justice (DOJ)—all of which maintain that Title II of the ADA (Title II), the integration mandate, and the U.S. Supreme Court’s decision in Olmstead v. L.C. ex rel. Zimring permit these claims. This Note explores how the circuit courts have evaluated risk of unnecessary institutionalization claims, including …


Imageinthat: Manipulating Images To Convey User Instructions To Robots, Karthik Mahadevan, Blaine Lewis, Jiannan Li, Bilge Mutlu, Anthony Tang, Tovi Grossman Mar 2025

Imageinthat: Manipulating Images To Convey User Instructions To Robots, Karthik Mahadevan, Blaine Lewis, Jiannan Li, Bilge Mutlu, Anthony Tang, Tovi Grossman

Research Collection School Of Computing and Information Systems

Foundation models are rapidly improving the capability of robots in performing everyday tasks autonomously such as meal preparation, yet robots will still need to be instructed by humans due to model performance, the difficulty of capturing user preferences, and the need for user agency. Robots can be instructed using various methods---natural language conveys immediate instructions but can be abstract or ambiguous, whereas end-user programming supports longer-horizon tasks but interfaces face difficulties in capturing user intent. In this work, we propose using direct manipulation of images as an alternative paradigm to instruct robots, and introduce a specific instantiation called ImageInThat which …

Selecting Comparative Sets Of Reviews Across Multiple Items, Trung Hoang Le, Hady Wirawan Lauw

Research Collection School Of Computing and Information Systems

While choosing among several products, users may look up reviews from each product they are considering. Due to the large number of reviews of products, selecting representative reviews from one product alone is already a challenging problem. In this work, we further aim to conduct review selection for multiple products simultaneously for comparative purposes. We formulate objective functions that synchronize the review selection and design efficient algorithms to optimize for the objective functions. To narrow down the potentially long list of comparison items into a shorter list of more similar items, we construct a graph representing items’ similarity and design …


Fully Selective Opening Secure Ibe From Lwe, Dingding Jia, Haiyang Xue, Bao Li Mar 2025

Fully Selective Opening Secure Ibe From Lwe, Dingding Jia, Haiyang Xue, Bao Li

Research Collection School Of Computing and Information Systems

Selective opening security ensures that, when an adversary is given multiple ciphertexts and corrupts a subset of the senders (thereby obtaining the plaintexts and the senders’ randomness), the privacy of the remaining ciphertexts is still preserved. Previous selective opening secure IBE schemes encrypt messages bit-by-bit, or only achieve selective-id security. In this paper, we present the first adaptive-id, selective opening secure identity-based encryption (IBE) tightly from LWE. To achieve this, we introduce a new primitive called delegatable all-but-many lossy trapdoor functions (DABM-LTDF) and provide a generic construction that converts DABM-LTDF into an adaptive-id, selective opening secure IBE through a tight …
