Redemption From The Inside-Out: The Power Of Faith-Based Programming, Barbara H. Zaitzow, Richard S. Jones

Social and Cultural Sciences Faculty Research and Publications

Prisons are tense, cheerless, and often degrading places in which all inmates struggle to maintain their equilibrium despite violence, exploitation, lack of privacy, stringent limitations on family and community contacts, and a paucity of opportunities for meaningful education, work, or other productive activities. As a general matter, prisoners come to see prison as their home and try to make the most of the limited resources available in prison; they establish daily routines that allow them to find meaning and purpose in their prison lives, lives that might otherwise seem empty and hopeless. The resilience shown by prisoners should not be …

Ensuring Decent Work For Domestic Workers: An Integral Approach To The Prevention Of Labor Trafficking, Mark Ensalaco

Intercultural Human Rights Law Review

The first section of this article situates labor trafficking, including domestic servitude, on a continuum of labor abuse and exploitation, by way of a discussion of the Convention Concerning Decent Work for Domestic Workers. Here the paper cautions against the equal and opposite dangers of categorizing all domestic labor abuse as domestic servitude on the one hand, and ignoring less severe forms of labor abuse, on the other. Moreover, it argues that the strict enforcement of ILO standards aimed at reducing labor abuse and exploitation is necessary to prevent involuntary labor, including involuntary labor in the home. The second section …

Life Without Boundaries: A Positive Deviance Inquiry Of Communication Behaviors That Influence Academic Success Of Learning-Disabled University Students, Davi Kallman

Open Access Theses & Dissertations

The label of "disabled" causes many learning-disabled students to downplay their disability in order to avoid alienation and isolation. Hence, many of learning-disabled students go through years of education without accommodations, increasing the likelihood for academic failure. Students who do have accommodations are still at risk of failure especially if they lack strong support systems and suffer from low expectations. Simply put, dropout rates among learning-disabled students are a complex social problem. The dropout rate among these students is nearly double that of general education students (Blackorby & Wagner, 1996). Dropping out has devastating financial, educational, and social repercussions for …

I conducted 150 door-to-door surveys and tested water samples from each household for free residual chlorine level, turbidity level, presence …

A Comparison Of The Basics Harm Reduction Approach And Personalized Normative Feedback For Reducing Alcohol-Related Behaviors Among Municipal Firefighters, Stormy Miracle Monks

Open Access Theses & Dissertations

Firefighting is a hazardous occupation due to the nature of firefighting duties including frequent exposure to traumatic events. Firefighters have been shown to cope with stress by drinking alcohol (Bacharach, Bamberger, & Doveh, 2008). Indeed, studies of firefighters have found that roughly 30% report being problem drinkers (Boxer & Wild, 1993) and 47% of firefighters have a diagnosis of alcohol abuse or dependence (North, Tivis, McMillen, Pfefferbaum, Spitznagel et al., 2002). Despite high rates of alcohol use, most firefighters receive inadequate training regarding alcohol and other risky behaviors. Furthermore, fire departments rarely act proactively regarding problems like alcohol consumption.

Functional Characterization Of P90/Cip2a In Human Lung Cancer, Bo Peng

Open Access Theses & Dissertations

p90/CIP2A is a recently characterized oncoprotein which promotes cancer cell proliferation through the inhibition of c-myc-associated PP2A phosphatase activity, from which it derived the name as cancerous inhibitor of PP2A (CIP2A). Although p90/CIP2A has been found to be overexpressed in various cancer types, from solid tumors to hematological malignancies, the function of this protein is still limited to its ability to regulate the stability of c-myc. The recent study showing p90/CIP2A is able to regulate the phosphorylation of protein kinase B (PKB) in response to the treatment of chemotherapy drugs implied p90/CIP2A may have more functions. In order to investigate …
