Faculty, Staff and Student Publications

Adverse childhood experiences, such as household dysfunction (HD), play a central role in how adolescents establish, experience, and navigate the challenges of relationship formation, maintenance, and dissolution. HD exposures have been independently associated with dating violence (DV) perpetration in both adolescents and adults. However, research examining the association between the concurrent effect of HD on DV perpetration, especially among adolescents remains scarce. Thus, we conducted a scoping review to accumulate and summarize existing research regarding the impact of HD on DV perpetration among adolescents aged 10 to 17 years in the United States. We used three electronic databases, Medline (Ovid), …

Information Production By Institutions And Information Extraction By Underwriters In Hybrid Ipo Auctions, Thomas J. Chemmanur, Pengfei Ma, Qianqian Yu

Research Collection Lee Kong Chian School Of Business

We analyze the informational properties of hybrid IPO auctions using a large and unique database of institutional bids from Chinese IPO auctions. We find strong evidence of information production by institutions about the intrinsic values of IPO firms and of underwriters extracting and using this information in IPO pricing. The IPO offer price is more sensitive to bids from institutions able to produce more precise information. In particular, the offer price is more sensitive to bids from domestic institutions, compared to bids from foreign institutions who likely have less knowledge or experience about the Chinese firms and financial market due …

For The Enemy Is No Longer Men, But Our Own Sisters: Anti-Era Activists Within The Feminist Narrative, Grace Chipman

AWE (A Woman’s Experience)

When Alice Paul drafted the Equal Rights Amendment (ERA) in 1923, she had hoped it would become a unifying document for women across America. However, forty-nine years later, when Congress passed the amendment, radical feminists led the charge for its ratification. Paul, a prominent feminist, feared that the amendment became so politicized it was tearing apart the women’s movement. Dianne Fife Kay, an anti-ERA activist, described the period as a time in which “the enemy was no longer men, but our own sisters.” As Paul had feared, radical feminism had ruptured the sisterhood that first-wave feminism created.

An Examination Of Katherine Philips And Aphra Behn: Differing Approaches To Male Authority Inside And Outside The Private Sphere, Sophie Hirtle

AWE (A Woman’s Experience)

Susa Young Gates Award 2024

Winner

The mid to late 1600s were a time of intense societal change in England as a result of the English Civil War and the abdication and restoration of the English monarchy. During this time of religious and political upheaval, those who had historically been silenced found more opportunities to speak up regarding recent changes. This was the case for Katherine Philips and Aphra Behn, two female writers who had their own distinct views on the recent political and religious upheaval. In past studies concerning these two women, there has been a trend of either …

Wearing The Pants: Patriarchal Breeches Roles In Oroonoko And The Rover, Emmalee Collyer

AWE (A Woman’s Experience)

Oroonoko and The Rover, or, the Banished Cavaliers are set in very different locations with a variety of colorful characters. Oroonoko features a split plot set in Suriname exploring the relationships between commerce, slavery, and marriage; whereas The Rover features the collision of three women and a group of cavaliers at Carnival in Naples. But these seemingly disparate plays do have something in common; both are popular adaptations by arguably progressive playwrights. Thomas Southerne adapted a novel by Aphra Behn into Oroonoko, and Aphra Behn adapted Thomas Killigrew’s Thomaso, or The Wanderer into The Rover. Both Southerne and …

Restoring Calibration For Aligned Large Language Models: A Calibration-Aware Fine-Tuning Approach, Jiancong Xiao, Bojian Hou, Zhanliang Wang, Ruochen Jin, Qi Long, Weijie J Su, Li Shen

Faculty, Staff and Student Publications

One of the key technologies for the success of Large Language Models (LLMs) is preference alignment. However, a notable side effect of preference alignment is poor calibration: while the pre-trained models are typically well-calibrated, LLMs tend to become poorly calibrated after alignment with human preferences. In this paper, we investigate why preference alignment affects calibration and how to address this issue. For the first question, we observe that the preference collapse issue in alignment undesirably generalizes to the calibration scenario, causing LLMs to exhibit overconfidence and poor calibration. To address this, we demonstrate the importance of fine-tuning with domain-specific knowledge …

Principal Component Analysis Of Emotion Related Concepts, Ana Kellermann Jimenez

Clinical Psychology Dissertations

Objective: To examine associations of serum imidazole propionate (ImP), histidine, and their ratio with incident type 2 diabetes (T2D) and related dietary and gut microbial factors in U.S. Hispanic/Latino people.

Research design and methods: In the Hispanic Community Health Study/Study of Latinos, we evaluated serum ImP, histidine, and ImP-to-histidine ratio at baseline (2008-2011) and their cross-sectional associations with dietary intake and prospective associations with incident T2D over ∼12 years (n = 4,632). In a subsample with gut microbiota data during a follow-up visit (2016-2018), we examined gut microbial species associated with serum ImP and their potential interactions with dietary intake. …

Undominated Mechanisms, Tilman Borgers, Jiangtao Li, Kexin Wang

Research Collection School Of Economics

We study the design of mechanisms when the designer faces multiple plausible scenarios and is uncertain about the true scenario. A mechanism is dominated by another if the latter performs at least as well in all plausible scenarios and strictly better in at least one. A mechanism is undominated if no other feasible mechanism dominates it. We show how analyzing undominated mechanisms could be useful and illustrate the tractability of characterizing such mechanisms. This approach provides an alternative criterion for mechanism design under non-Bayesian uncertainty, complementing existing methods.

How do advanced technology adoption and venture capital (VC) funding impact employment and growth? An analysis of data from the US Census Bureau suggests that while both advanced technology use and VC funding matter on their own for firm outcomes, their joint presence is most strongly correlated with higher employment levels. VC presence is linked with a high increase in employment, though primarily among a limited subset of firms. In contrast, technology adoption is associated with a smaller rise in employment, yet it influences a considerably larger number of firms. A model of startups is created, focusing on decisions to …

The Aggregate Welfare And Trade Implications Of Contracting Frictions In Global Sourcing, Davin Chor, Lin Ma

Research Collection School Of Economics

How much do contracting frictions between global firms and their suppliers impact country welfare and trade? We answer this by developing a model of global sourcing under partial contractibility, where firm-supplier relationships are exposed to a bilateral holdup problem. Sourcing decisions aggregate into a gravity equation for trade flows by organizational mode (intrafirm vs. arm’s length), which we take to structural estimation. We can then evaluate welfare changes with an extended Arkolakis, Costinot and Rodriguez-Clare (2012) formula that incorporates these contracting frictions. Our counterfactual analysis reveals a sizeable average country welfare gain of 9.2% from eliminating contracting frictions in global …
