Design, Determination, And Evaluation Of Gender-Based Bias Mitigation Techniques For Music Recommender Systems, Sunny Shrestha

Electronic Theses and Dissertations

The majority of smartphone users engage with a recommender system on a daily basis. Many rely on these recommendations to make their next purchase, download the next game, listen to the new music or find the next healthcare provider. Although there are plenty of evidence backed research that demonstrates presence of gender bias in Machine Learning (ML) models like recommender systems, the issue is viewed as a frivolous cause that doesn’t merit much action. However, gender bias poses to effect more than half of the population as by default ML systems are designed to cater to a cisgender man. This …

Perceptions Of Quality Of Healthcare Using A Trauma-Informed Care Perspective Among Trauma Survivors, Jane Axelle Komen

Theses and Dissertations

Trauma is an all-too-common occurrence with the potential for several farreaching, deleterious effects both mentally and physically. Several studies have found an association between exposure to trauma and cardiovascular, immune, and musculoskeletal system complications. It has also been linked to chronic pain, cancer, and obesity, in addition to several functional and structural neurological effects. Trauma survivors have also been found to utilize healthcare services at a higher rate than those who have not reported experiencing trauma. Trauma-informed care is a relatively novel concept that has been introduced to increase the sensitivity with which these individuals are treated when attending healthcare …

Information Costs And The Civil Justice System, Keith N. Hylton

Faculty Scholarship

Litigation is costly because information is not free. Given that information is costly and perfect information prohibitively costly, courts will occasionally err. Finally, the fact that information is costly implies an unavoidable degree of informational asymmetry between disputants. This paper presents a model of the civil justice system that incorporates these features and probes its implications for compliance with the law, efficiency of law, accuracy in adjudication, trial outcome statistics, and the evolution of legal standards. The model’s claims are applied to and tested against the relevant empirical and legal literature. (JEL: D74, K10, K13, K41)

Forgotten Parties: Shifting The Focus Of Donor Conception To Donor-Conceived Persons Through Reasonable Regulation, Tiffany D. Gardner

Mercer Law Review

In an age in which information is at our fingertips with a few keystrokes, members of the fertility industry are increasingly confronting the reality that anonymous sperm and egg donation is no longer realistic—and has not been for some time. With the advent of at-home commercial DNA testing, multiple generations are not only learning they were conceived through the use of reproductive material provided by third parties (“donors”) but also identifying those formerly anonymous donors. These revelations, and increasing advocacy by the people born of such donations (i.e., donor-conceived people) are changing the landscape of third-party reproduction around the world. …

Conflict Of Laws? Tensions Between Antitrust And Labor Law, Matthew Dimick

University of Chicago Law Review

Not long ago, economists denied the existence of monopsony in labor markets. Today, scholars are talking about using antitrust law to counter employer wagesetting power. While concerns about inequality, stagnant wages, and excessive firm power are certainly to be welcomed, this sudden about-face in theory, evidence, and policy runs the risk of overlooking some important concerns. The purpose of this Essay is to address these concerns and, more critically, to discuss some tensions between antitrust and labor law, a more traditional method for regulating labor markets. Part I addresses a question raised in the very recent literature, about why antitrust …

Losing Leverage: Employee Replaceability And Labor Market Power, Cynthia Estlund

University of Chicago Law Review

Workers’ labor market power matters enormously to their lives at work and beyond. And most workers have too little of it. This Essay highlights one underappreciated set of factors in the decline of workers’ labor market power and explores policy levers that might help to rebalance the bargaining field. This Essay begins with the fairly self-evident observation that workers’ labor market power is a product in part of the ease with which employers can replace employees. That points to the importance of several trends in the organization and technology of work—including both fissuring and automation—that make it easier for private …

Michigan Tech Publications, Part 1

Nondestructive and contactless online approaches for detecting defects in polymer films are of significant interest in manufacturing. This paper develops vision-based quality metrics for detecting the defects of width consistency, film edge straightness, and specks in a polymeric film production process. The three metrics are calculated from an online low-cost grayscale camera positioned over the moving film before the final collection roller and can be implemented in real-time to monitor the film manufacturing for process and quality control. The objective metrics are calibrated to correlate with an expert ranking of test samples, and results show that they can be used …

Flextype: Flexible Text Input With A Small Set Of Input Gestures, Dylan Gaines, Mackenzie M. Baker, Keith Vertanen

Michigan Tech Publications, Part 1

In many situations, it may be impractical or impossible to enter text by selecting precise locations on a physical or touchscreen keyboard. We present an ambiguous keyboard with four character groups that has potential applications for eyes-free text entry, as well as text entry using a single switch or a brain-computer interface. We develop a procedure for optimizing these character groupings based on a disambiguation algorithm that leverages a long-span language model. We produce both alphabetically-constrained and unconstrained character groups in an offline optimization experiment and compare them in a longitudinal user study. Our results did not show a significant …
