The Human Myocardium Harbors A Population Of Naive B-Cells With A Distinctive Gene Expression Signature Conserved Across Species, Kevin C Bermea, Nicolas Kostelecky, Sylvie T Rousseau, Chieh-Yu Lin, Luigi Adamo

2020-Current year OA Pubs

INTRODUCTION: Cardiac immunology studies in murine models have identified a sizeable population of myocardial B-cells and have shown that its modulation represents a promising strategy to develop novel therapies for heart failure. However, scarce data on B-cells in the human heart leaves unclear whether findings in rodents are relevant to human biology.

METHODS: We performed immunohistochemical stains to characterize the amount and distribution of B-cells in human hearts, analyzing both fresh and post-mortem tissue. To gain insight into the biology of human myocardial B-cells we analyzed publicly-available spatial transcriptomics and single-cell sequencing datasets of myocardial and peripheral blood mononuclear cells …

Lively Emu Dialogues: Activating Feminist Common Worlding Pedagogies, Mindy Blaise, Catherine Hamm

Research outputs 2014 to 2021

This paper draws from a series of Place-thought walks that the authors took at an open-range zoo. It practices a feminist common worlds multispecies ethics to challenge the systems that maintain nature-culture divisions in early childhood education. Postdevelopmental perspectives (i.e., feminist environmental humanities, multispecies studies, Indigenous studies) are brought into conversation with early childhood education to consider how zoo-logics maintain binaries and hierarchical thinking. Zoo-logics are related to developmental, colonial, and Western ways of reasoning and being in the world. Two feminist approaches to ethics, (re)situating and dialoguing, are discussed and show how they are necessary for undermining binaries and …

Election Laws And Voter Turnout In The United States, Sofia Papoutsis

Res Publica - Journal of Undergraduate Research

Over the last decade, electoral reform has become a topic of intense controversy in the United States. While Republicans highlight the need for strict voting laws to prevent voter fraud and maintain election integrity, Democrats argue that these laws create barriers to voting and decrease voter turnout. How have U.S. voting laws evolved over the last decade? How do these changes affect voter turnout? Which voting laws have the greatest impact on voter turnout? Researchers Larocca and Klemanski (2011) provide answers to some of these questions through an empirical analysis on the effects of state-level election laws and reforms on …

Racial Party Polarization Under Donald Trump, Kate Berman

Res Publica - Journal of Undergraduate Research

Growing party polarization directly results from increasing economic inequalities, racial tensions and the idea that the white majority is now a minority. This paper identifies the sources of party polarization. Combining social, economic, and racial factors, it builds on popular scholarly works that show white people feel left behind. Acknowledging that income inequality is the root of polarization, the paper argues that the interaction between race, economics and social status provides a more well-rounded look at party polarization. Party polarization has caused an increase in non-college-educated people participating in voting. This, in turn, led to Donald Trump’s popularity. This study …

Urgenda Foundation V. State Of The Netherlands (2015) And Associated Policy Impacts, Emile C. Ottinger

Res Publica - Journal of Undergraduate Research

Climate change is a global issue that calls for global responses. It is also crucial to address regionally, according to each state’s best ability, and respond to regionally-felt impacts. Often, this regional change must begin with individual and community action. The Urgenda Foundation v. State of the Netherlands case is a crucial example of how individual interests and community actions can create regional change and result in global change through concentrated effort. The Urgenda Foundation was created to promote national shifts toward sustainable societies. It facilitates the integration of individuals’ sustainable interests into community action. As the first legal success …

Increased Virus Dissemination Leads To Enhanced Lung Injury But Not Inflammation During Influenza-Associated Secondary Bacterial Infection, Amanda P Smith, Lindey C Lane, Ivan Ramirez Zuniga, David M Moquin, Peter Vogel, Amber M Smith

2020-Current year OA Pubs

Secondary bacterial infections increase influenza-related morbidity and mortality, particularly if acquired after 5-7 d from the viral onset. Synergistic host responses and direct pathogen-pathogen interactions are thought to lead to a state of hyperinflammation, but the kinetics of the lung pathology have not yet been detailed, and identifying the contribution of different mechanisms to disease is difficult because these may change over time. To address this gap, we examined host-pathogen and lung pathology dynamics following a secondary bacterial infection initiated at different time points after influenza within a murine model. We then used a mathematical approach to quantify the increased …

Fifth Graders’ Use Of Gesture And Models When Translanguaging During A Content And Language Integrated Science Class In Hong Kong, Melanie Williams

Research outputs 2014 to 2021

Translanguaging in science includes the use of semiotic repertoires complete with non-linguistic modes of meaning (e.g. gesture, tactile) that until recently have gone unnoticed in research into content language integrated learning (CLIL). Currently, there are calls for classroom research in CLIL settings that examines the semiotic processes in the spontaneous translanguaging of emergent bilinguals. In response, this study aims to expand bilingualism research by investigating the ways in which fifth-grade emergent bilinguals’ draw from their semiotic repertoires when translanguaging in content-based science lessons. Multimodal transcriptions made from video recordings of the lessons allow a cross-case analysis of the emergent bilinguals’ …

Why Franchisors Recruit Franchisees From The Ranks Of Their Employees, Peter Balsarini, Claire Lambert, Maria M. Ryan

Research outputs 2014 to 2021

A shortage of suitable franchisees has long plagued the Australian franchise industry impacting franchisors’ capacity to grow their chains. This exploratory research identifies, defines and examines an unresearched category of franchisees that of internally recruited franchisees, who prior to their franchise recruitment were employees of the franchisor. This category has previously been ignored by the literature even though estimates of some chains place the proportion of internally recruited franchisees at over 40 per cent. Employing qualitative interviews with key franchisor decision makers this research begins to address this gap. This study investigates what factors drive franchisors to recruit franchisees from …

Comparison Of Weightlifting, Traditional Resistance Training And Plyometrics On Strength, Power And Speed: A Systematic Review With Meta-Analysis, Stephanie J. Morris, Jon L. Oliver, Jason S. Pedley, G. Gregory Haff, Rhodri S. Lloyd

Research outputs 2022 to 2026

Background:

Weightlifting training (WLT) is commonly used to improve strength, power and speed in athletes. However, to date, WLT studies have either not compared training effects against those of other training methods, or been limited by small sample sizes, which are issues that can be resolved by pooling studies in a meta-analysis. Therefore, the objective of this systematic review with meta-analysis was to evaluate the effects of WLT compared with traditional resistance training (TRT), plyometric training (PLYO) and/or control (CON) on strength, power and speed.

Methods:

The systematic review included peer-reviewed articles that employed a WLT intervention, a comparison group …
