Studying Vulnerable Populations Through An Epigenetics Lens: Proceed With Caution, Katie Saulnier, Alison Berner, Stamatina Liosi, Brian Earp, Courtney D. Berrios, Stephanie O.M. Dyke, Charles Dupras, Yann Joly

Manuscripts, Articles, Book Chapters and Other Papers

Epigenetics – the study of mechanisms that influence and modify gene expression – is providing unique insights into how an individual’s social and physical environment impact the body at a molecular level, particularly in populations that experience stigmatization and trauma. Researchers are employing epigenetic studies to illuminate how epigenetic modifications lead to imbalances in health outcomes for vulnerable populations. However, the investigation of factors that render a population epigenetically vulnerable present particular ethical and methodological challenges. Here we are concerned with demonstrating how, in targeting certain populations for epigenetic research, this research may be pathologizing socio-cultural and medical practices in …

Implementing Nih Behavior Change Consortium Treatment Fidelity Recommendations In A Multi-Site Randomized Controlled Trial Of An Active Music Engagement Intervention For Young Children With Cancer And Parents., Jessica A. Maclean, Kristin Stegenga, Amanda K. Henley, Sheri L. Robb

Manuscripts, Articles, Book Chapters and Other Papers

Treatment fidelity is the use of methodological strategies to monitor and enhance reliability and validity of behavioral intervention trials. Despite availability of guidelines and checklists, treatment fidelity remains underreported, hindering evaluation, interpretation, and cross-study comparisons. Treatment fidelity is particularly important for music interventions given the inherent complexity of musical stimuli and flexibility required for tailored delivery. The purpose of this paper is to define and describe treatment fidelity strategies for our trial of a music-based play intervention for young children with cancer and parents grounded in the NIH Behavior Change Consortium Treatment Fidelity Recommendations. We report strategies for all 5 …

Faculty Scholarship

In this Essay, we explore how responsibility based on culpability, moral accountability, and capability can improve the current regime that rests on responsibility by proximity. In doing so, we draw on the 2017 Model International Mobility Convention (MIMC), a model convention drafted by a commission of independent experts and currently supported as a project of the Carnegie Council for Ethics in International Affairs.

The Field Of State Civil Courts, Anna E. Carpenter, Alyx Mark, Colleen F. Shanahan, Jessica K. Steinberg

Faculty Scholarship

This symposium Issue of the Columbia Law Review marks a moment of convergence and opportunity for an emerging field of legal scholarship focused on America’s state civil trial courts. Historically, legal scholarship has treated state civil courts as, at best, a mere footnote in conversations about civil law and procedure, federalism, and judicial behavior. But the status quo is shifting. As this Issue demonstrates, legal scholars are examining our most common civil courts as sites for understanding law, legal institutions, and how people experience civil justice. This engagement is essential for inquiries into how courts shape and respond to social …

Intellectual Property, Independent Creation, And The Lockean Commons, Mala Chatterjee

Faculty Scholarship

Copyrights and patents are differently structured intellectual property rights in different kinds of entities. Nonetheless, they are widely regarded by U.S. scholars as having the same theoretical underpinnings. Though scholars have sought to connect philosophical theories of property to intellectual property, with a particular interest in the labor theory of John Locke, these explorations have not sufficiently probed copyrights’ and patents’ doctrinal differences or their philosophical implications for the theories explored. This Article argues that a defining difference between copyrights and patents has normative significance for the framework of Lockean property theory: namely, that copyright law treats independent creation as …

Effects Of Socioeconomic Status, Demographic Characteristics, And Education On Sarcopenic Obesity, Moruf Oladele Olaleye

Walden Dissertations and Doctoral Studies

The general problem is that although the body of research about obesity is robust, there is a lack of research addressing the problem of sarcopenic obesity. Specifically, there is a lack of research examining the statistical significance of the relationship between the independent variables of socioeconomic status, demographic characteristics, and education and the dependent variable of sarcopenic obesity. This research may advance practice and policy by lending support for developing interventions to address factors that have a statistically significant relationship with sarcopenic obesity. The purpose of this quantitative causal-comparative study was to identify independent variables among socioeconomic, demographic, and education …

Semiparametric Copula-Based Regression Modeling Of Semi-Competing Risks Data, Hong Zhu, Yu Lan, Jing Ning, Yu Shen

Faculty, Staff and Student Publications

Semi-competing risks data often arise in medical studies where the terminal event (e.g., death) censors the non-terminal event (e.g., cancer recurrence), but the non-terminal event does not prevent the subsequent occurrence of the terminal event. This article considers regression modeling of semi-competing risks data to assess the covariate effects on the respective non-terminal and terminal event times. We propose a copula-based framework for semi-competing risks regression with time-varying coefficients, where the dependence between the non-terminal and terminal event times is characterized by a copula and the time-varying covariate effects are imposed on two marginal regression models. We develop a two-stage …

Faculty, Staff and Student Publications

Numerous studies have revealed the critical role of premature senescence induced by various cancer treatment modalities in the pathogenesis of aging-related diseases. Senescence-associated secretory phenotype (SASP) can be induced by telomere dysfunction. Telomeric DNA damage response induced by some cancer treatments can persist for months, possibly accounting for long-term sequelae of cancer treatments. Telomeric DNA damage-induced mitochondrial dysfunction and increased reactive oxygen species production are hallmarks of premature senescence. Recently, we reported that the nucleus-mitochondria positive feedback loop formed by p90 ribosomal S6 kinase (p90RSK) and phosphorylation of S496 on ERK5 (a unique member of the mitogen-activated protein kinase family …
