Theoretical Analysis Of The Leakage Through The Cement Line Of A Single Osteon, Gaffar Gailani, Stephen Cowin

Publications and Research

This work focuses on the Lacunar–Canalicular Porosity (PLC) of cortical bone which includes the osteons. Osteons are semicylindrical porous structures saturated with fluid within the bone and are approximately 250" role="presentation">μ" role="presentation">μm in diameter. The outer boundary of the osteon is called the cement line. Some studies suggested that the cement line is less highly mineralized and produced evidence that it has less calcium and phosphorus and more sulfur than the neighboring bone lamellae. Most authors assume that the cement line is impermeable, while others assume that some canaliculi are crossing the cement line which will make it …

Work Alienation And Its Gravediggers: Social Class, Class Consciousness, And Activism, Jeremy Sawyer, Anup Gampa

Publications and Research

Work activity is central to human psychology. However, working conditions under capitalist socioeconomic relations have been posited as psychologically alienating. Given the negative impact of work alienation on well-being and mental health, we conducted two studies of the relations between social class, work conditions, and alienation. We also examined factors that might counteract alienation – class consciousness and activism. The utility of a Marxist measure of social class – based on objective work relations – was compared with that of SES and subjective class measures. Study 1 surveyed 240 U.S. adults from diverse socioeconomic backgrounds using Amazon’s Mechanical Turk; Study …

The Public Reckoning: Anti-Debt Futures After #Rickyrenuncia, Sarah Molinari

Publications and Research

This essay argues that the summer 2019 mobilizations in Puerto Rico and the renewed demand for a debt audit help to imagine anti-debt futures that disrupt the terms and temporalities of public debt and indebted lives. The essay discusses one form of debt resistance-a comprehensive citizen debt audit-as central to deepen the process of public reckoning marked by #RickyRenuncia and to build upon the landscapes of protest and solidarity emerging in its wake.

Transposon Mutagenesis In Mycobacterium Kansasii Links A Small Rna Gene To Colony Morphology And Biofilm Formation And Identifies 9,885 Intragenic Insertions That Do Not Compromise Colony Outgrowth, William C. Budell, Gabrielle A. Germain, Niklas Janisch, Zaid Mckie-Krisberg, Anitha D. Jayaprakash, Andrew E. Resnick, Luis E. N. Quadri

Publications and Research

Mycobacterium kansasii (Mk) is a resilient opportunistic human pathogen that causes tuberculosis-like chronic pulmonary disease and mortality stemming from comorbidities and treatment failure. The standard treatment of Mk infections requires costly, long-term, multidrug courses with adverse side effects. The emergence of drug-resistant isolates further complicates the already challenging drug therapy regimens and threatens to compromise the future control of Mk infections. Despite the increasingly recognized global burden of Mk infections, the biology of this opportunistic pathogen remains essentially unexplored. In particular, studies reporting gene function or generation of defined mutants are scarce. Moreover, no transposon (Tn) mutagenesis tool has been …

Effects Of Speech Cues In French-Speaking Children With Dysarthria, Erika S. Levy, Gemma Moya-Galé, Younghwa Michelle Chang, Luca Campanelli, Andrea A. N. Macleod, Sergio Escorial, Christelle Maillart

Publications and Research

Background: Articulatory excursion and vocal intensity are reduced in many children with dysarthria due to cerebral palsy (CP), contributing to the children’s intelligibility deficits and negatively affecting their social participation. However, the effects of speech-treatment strategies for improving intelligibility in this population are understudied, especially for children who speak languages other than English. In a cueing study on English-speaking children with dysarthria, acoustic variables and intelligibility improved when the children were provided with cues aimed to increase articulatory excursion and vocal intensity. While French is among the top 20 most spoken languages in the world, dysarthria and its management in …

Raw Veganism: The Human Diet, Carlo Alvaro

Publications and Research

In this chapter, I present some compelling evidence that points to the conclusion that the human species has a specific diet, which is a raw vegan diet of fresh fruit, tender leafy greens, and a moderate amount of nuts and seeds. Out of the hundreds of thousands of species in the world, the only one—ours—cooks food. Not surprisingly, our species is the only one that suffers from numerous maladies. In other words, the argument is that the consumption of cooked food (especially animal-based) is unhealthful and undermines our nature. I present undeniable evidence, from evolutionary science to nutrition science, showing …

Three dimensional (3D) printing as an advanced manufacturing technology is progressing to be established in the pharmaceutical industry to overcome the traditional manufacturing regime of ʹone size fits for allʹ. Using 3D printing, it is possible to design and develop complex dosage forms that can be suitable for tuning drug release. Polymers are the key materials that are necessary for 3D printing. Among all 3D printing processes, extrusion‐based (both fused deposition modeling (FDM) and pressure‐assisted microsyringe (PAM)) 3D printing is well researched for pharmaceutical manufacturing. It is important to understand which polymers are suitable for extrusion‐based 3D printing of pharmaceuticals …

Evaluation Of Health Literacy And Depression Literacy Among Korean Americans, Kunsook Bernstein, Shinhi Han, Young-Me Lee, Oisaeng Hong

Publications and Research

Low health literacy is closely related to a higher rate of hospitalization and of emergency services usage, leading to billions of dollars in avoidable health care costs and contributing to individuals’ poor physical and mental health. While Korean Americans (KAs) have a high prevalence of general health and mental health problems, relatively little is known about their health and mental health literacy, specifically their depression literacy. This study aims to evaluate KAs’ health literacy and depression literacy, as related to sociodemographic characteristics. An exploratory study was conducted with 681 community-residing adult KAs using the Center for Epidemiologic Studies Depression (CES-D) …

Open To What? A Critical Evaluation Of Oer Efficacy Studies, Ian Mcdermott

Publications and Research

This selective literature review evaluates open educational resources (OER) efficacy studies through the lens of critical pedagogy. OER have radical potential as transformative tools for critical pedagogy or they can serve as a cost-free version of the status quo, inclined toward propagating austerity. This review analyzes studies published since 2008 with regard to cost, access, pedagogy, commercialization, and labor. These criteria are used to make explicit subjects indirectly addressed, if not ignored completely, in the existing literature. Typically, ample attention is paid to a study’s design and methodology but the underlying institutional infrastructure and decision-making process is unexamined. What emerges …

Google Street View (GSV) images can be used to “ground-truth” current and historical food retail data from approximately 2007 - when GSV was launched in a few US cities - to the present, facilitating analyses of food environments over time. A review of GSV images of all food retailers listed in a government database of licensed establishments in the Bronx, New York enabled records to be verified, businesses classified, and retail change quantified. The data revealed several trends likely to affect food access and health: increasing overall numbers of food retailers; the growth of dollar stores; and numerous openings, closings, …

Recording Studios Since 1970, Eliot Bates

Publications and Research

Like many other specialty, purpose-built spaces, we tend to think of recording studios in instrumental terms, meaning that the space is defined in relation to the nominal type of work that the space is instrumental towards. While audio recordings have been made in spaces since 1877, not all of these spaces tend to be regarded as recording studios, partly since so many recordings were made in environments designed for other types of work; indeed, much of the first seventy years of US and UK recorded music history transpired at radio stations, concert halls and lightly treated mixed-use commercial spaces (e.g. …

Tests Of Revisions To The Norbeck Social Support Questionnaire, Eileen Gigliotti, William Ellery Samuels

Publications and Research

Objectives:To compare the accuracy of averaged scores from the original Norbeck Social Support Questionnaire (NSSQ)and averaged scores from each of three new NSSQ versions (NSSQ-R.aid, NSSQ-R.n/a, and NSSQ-R.format). These three new versions of the widely used NSSQ were developed to address three previously identified concerns regarding score accuracy: the Aid subscale’s examples of aid, lack of an n/a response option, and the network nomination/rating procedure.Missing data rates were also assessed.Methods:A convenience sample (N=223) completed one of the four NSSQ versions. Score accuracy (restriction) was assessed by size of correlation between averaged scores (averaged score/network size) and network size, with low …

Capitalism And The Immigrant Rights Movement In The United States, Marcel Paret, Sofya Aptekar, Shannon Gleeson

Publications and Research

Social movements are full of contradictions, and an inherent tension often emerges between reformist and radical flanks. This becomes especially true as activists attempt to draw connections between varied aims such as opposition to globalization and support for immigrants. During the 1999 Battle of Seattle, the movement focused on opposing neoliberalism (Graeber 2002) and advocating for alternative visions of globalization (Reitan 2012). Some activists also noted the hypocrisy of opening borders to capital while militarizing the borders for migrants. Yet, in the end, immigrant rights movements and their central issues did not feature prominently in Seattle or later anti-globalization efforts. …

Weaving Forms Of Resistance: The Museo De La Solidaridad And The Museo Internacional De La Resistencia Salvador Allende, Carla Macchiavello Cornejo

Publications and Research

From the starting point of a 1975 artwork made by Norwegian artist Kjartan Slettemark in Sweden to stop a tennis match in resistance to the Chilean military dictatorship, this article reframes the linear image of networks of solidarity and resistance through the gaps and connectivity of a mesh. It expands the figure of the mesh taken from critical materialism into the affective realm of art, historiography, and art institutions by exploring the cases of the museums Museo de la Solidaridad (1971–1974) and Museo Internacional de la Resistencia “Salvador Allende” (1975–1990). As this article delves into various knots and lacunas of …

I Was Called, Too: The Life And Work Of Coretta Scott King, Kristopher B. Burrell

Publications and Research

I thought it both appropriate—and overdue—to discuss the significance of Coretta Scott King. And not just as the wife, and eventual widow, of Martin Luther King; but as an important activist and shaper of Dr. King’s ideas. Mrs. King was a significant figure in her own right, but as with many female historical figures her historical importance has often been minimized or negated; and that can lead to erasure, even in plain sight. This has largely been the case with Mrs. King and with black women in the civil rights movement more broadly.

We Need A Loud And Fractious Poor, Jeff Maskovsky, Frances Fox Piven

Publications and Research

This article explores the political consequences of four decades of consistent humiliation of the poor by the most authoritative voices in the land, and offers insights into ways that new movements are creating spaces for poor people’s political voices to surface and become relevant again. Our specific concern is the challenge that the current humiliation regime poses to those who seek to revive radical, disruptive and fractious anti-poverty activism and politics. By humiliation regime, we mean a form of political violence that maltreats those classified popularly and politically as “the poor” by treating them as undeserving of citizenship, rights, public …

In Vitro Evaluation Of The Influence Of Substrate Mechanics On Matrix-Assisted Human Chondrocyte Transplantation, Yueh-Hsun Kevin Yang, Courtney R. Ogando, Gilda A. Barabino

Publications and Research

Matrix-assisted chondrocyte transplantation (MACT) is of great interest for the treatment of patients with cartilage lesions. However, the roles of the matrix properties in modulating cartilage tissue integration during MACT recovery have not been fully understood. The objective of this study was to uncover the effects of substrate mechanics on the integration of implanted chondrocyte-laden hydrogels with native cartilage tissues. To this end, agarose hydrogels with Young’s moduli ranging from 0.49 kPa (0.5%, w/v) to 23.08 kPa (10%) were prepared and incorporated into an in vitro human cartilage explant model. The hydrogel-cartilage composites were cultivated for up to 12 weeks …

A Revision Of The Buechner–Tavani Model Of Digital Trust And A Philosophical Problem It Raises For Social Robotics, Jeff Buechner

Publications and Research

In this paper the Buechner–Tavani model of digital trust is revised—new conditions for self-trust are incorporated into the model. These new conditions raise several philosophical problems concerning the idea of a substantial self for social robotics, which are closely examined. I conclude that reductionism about the self is incompatible with, while the idea of a substantial self is compatible with, trust relations between human agents, between human agents and artificial agents, and between artificial agents.
