Improving The Lives Of Individuals In Financial Distress Using A Randomized Control Trial: A Research And Clinical Approach, Lois R. Lupica, Dalie´ Jimenez, D. James Greiner, Rebecca L. Sandefur Jan 2013

Improving The Lives Of Individuals In Financial Distress Using A Randomized Control Trial: A Research And Clinical Approach, Lois R. Lupica, Dalie´ Jimenez, D. James Greiner, Rebecca L. Sandefur

Faculty Publications

This Article describes an ambitious Randomized Control Trial (RCT) in the area of consumer debt collection. Randomized trials are the same kind of evaluation that the law requires (or at least strongly encourages) before new drugs and medical devices may be sold to the public. Although they have not yet gained widespread popularity in the evaluation of legal systems, randomized trials are uniquely effective ways of assessing whether any benefits observed after implementation of legal or educational assistance programs are really due to those programs as compared to other factors, such as unusual levels of competence or motivation of program …

Defunding State Prisons, W. David Ball Jan 2013

Defunding State Prisons, W. David Ball

Faculty Publications

Local agencies drive criminal justice policy, but states pick up the tab for policy choices that result in state imprisonment. This distorts local policies and may actually contribute to increased state prison populations, since prison is effectively “free” to the local decisionmakers who send inmates there. This Article looks directly at the source of the “correctional free lunch” problem and proposes to end state funding for prisons. States would, instead, reallocate money spent on prisons to localities to use as they see fit — on enforcement, treatment, or even per-capita prison usage. This would allow localities to retain their decision-making …

We have examined the formation of environmentally persistent free radicals (EPFRs) from phenol over alumina and titania using both powder and single-crystal samples. Electron paramagnetic resonance (EPR) studies of phenol adsorbed on metal oxide powders indicates radical formation on both titania and alumina, with both oxides forming one faster-decaying species (lifetime on the order of 50-100 h) and one slower-decaying species (lifetimes on the order of 1000 h or more). Electron energy loss spec- troscopy (EELS) measurements comparing physisorbed phenol on single-crystal TiO2(1 1 0) to phenoxyl radicals on the same substrate indicate distinct changes in the π-π* transitions from …

Impact Of Obesity On Il-12 Family Gene Expression In Insulin Responsive Tissues, Heesun Nam, Bradley S. Ferguson, Jacqueline M. Stephens, Ron F. Morrison Jan 2013

Impact Of Obesity On Il-12 Family Gene Expression In Insulin Responsive Tissues, Heesun Nam, Bradley S. Ferguson, Jacqueline M. Stephens, Ron F. Morrison

Faculty Publications

Mounting evidence has established a role for chronic inflammation in the development of obesity-induced insulin resistance, as genetic ablation of pro-inflammatory cytokines and chemokines elevated in obesity improves insulin signaling in vitro and in vivo. Recent evidence further highlights interleukin (IL)-12 family cytokines as prospective inflammatory mediators linking obesity to insulin resistance. In this study, we present empirical evidence demonstrating that IL-12 family related genes are expressed and regulated in insulin-responsive tissues under conditions of obesity. First, we report that respective mRNAs for each of the known members of this cytokine family are expressed within detectable ranges in WAT, skeletal …

Faculty Publications

Two zinc(II) phthalocyanines (ZnPcs) were conjugated with a monoclonal antibody (MAb) directed against carcinoembryonic antigen (CEA), using an in situ activated carboxylic acid on the ZnPcs. The bioconjugate with the highest ZnPc/MAb ratio of 3 was investigated in vitro for its ability to target and fluorescently label human colorectal HT-29 cells. The ZnPc-CEA MAb 2 was observed to efficiently target HT-29 cells, about 37 times more than unconjugated ZnPc. Furthermore, in the presence of a 4-fold excess of unlabelled anti-CEA antibody, the fluorescence signal of 2 was reduced by ∼90% showing that the targeting is CEA-mediated. These studies further confirm …

Faculty Publications

Among the EGFRs, HER2 is a major heterodimer partner and also has important implications in the formation of particular tumors. Interaction of HER2 protein with other EGFR proteins can be modulated by small molecule ligands and, hence, these protein-protein interactions play a key role in biochemical reactions related to control of cell growth. A peptidomimetic (compound 5-1) that binds to HER2 protein extracellular domain and inhibits protein-protein interactions of EGFRs was conjugated with BODIPY (4,4-difluoro-5,7-dimethyl-4-bora-3a,4a-diaza- s-indacene). Conjugation of BODIPY to the peptidomimetic was investigated by different approaches. The conjugate was characterized for its ability to bind to HER2 overexpressing SKBR-3 …

Requirement Of Vesicle-Associated Membrane Protein 721 And 722 For Sustained Growth During Immune Responses In Arabidopsis., Hye Sup Yun, Mark Kwaaitaal, Naohiro Kato, Changhyun Yi, Sohyeon Park, Masa H. Sato, Paul Schulze-Lefert, Chian Kwon Jan 2013

Requirement Of Vesicle-Associated Membrane Protein 721 And 722 For Sustained Growth During Immune Responses In Arabidopsis., Hye Sup Yun, Mark Kwaaitaal, Naohiro Kato, Changhyun Yi, Sohyeon Park, Masa H. Sato, Paul Schulze-Lefert, Chian Kwon

Faculty Publications

Extracellular immune responses to ascomycete and oomycete pathogens in Arabidopsis are dependent on vesicle-associated secretion mediated by the SNARE proteins PEN1 syntaxin, SNAP33 and endomembrane-resident VAMP721/722. Continuous movement of functional GFP-VAMP722 to and from the plasma membrane in non-stimulated cells reflects the second proposed function of VAMP721/722 in constitutive secretion during plant growth and development. Application of the bacterium-derived elicitor flg22 stabilizes VAMP721/722 that are otherwise constitutively degraded via the 26S proteasome pathway. Depletion of VAMP721/722 levels by reducing VAMP721/722 gene dosage enhances flg22-induced seedling growth inhibition in spite of elevated VAMP721/722 abundance. We therefore propose that plants prioritize the …

Sodium Dodecyl Benzene Sulfonate Modified Layered Double Hydroxides As A Photocatalyst Under Simulated Solar Radiation For Removal Of Malachite Green, C. X. Chen, Y. C. Hou, B. Li, W. Z. Yi Jan 2013

Sodium Dodecyl Benzene Sulfonate Modified Layered Double Hydroxides As A Photocatalyst Under Simulated Solar Radiation For Removal Of Malachite Green, C. X. Chen, Y. C. Hou, B. Li, W. Z. Yi

Faculty Publications

Sodium dodecyl benzene sulfonate modified layered double hydroxides (DBS-modified-LDHs) were prepared by low saturated state of coprecipitation with microwave assisted crystallization. The resulting samples were characterized by XRD, FT-IR, TEM and ICP-OES. The analytical results show that the as-produced DBS-modified-LDHs have good dispersibility while maintaining the structure of LDHs, indicating the use of microwave irradiation to speed up catalyst preparation is feasible. The formula of the DBS-modified-LDHs was calculated to be Mg2.85Al(OH)7.69(CO3)0.46 (DBS)0.089•2.88H2O, which is in agreement with the FT-IR results. After calcination, the resulting sodium dodecyl benzene sulfonate modified layered double oxide (DBS-modified-LDO) was used for the decolourization of …

Race In Biological And Biomedical Research, Richard S. Cooper Jan 2013

Race In Biological And Biomedical Research, Richard S. Cooper

Faculty Publications

The concept of race has had a significant influence on research in human biology since the early 19th century. But race was given its meaning and social impact in the political sphere and subsequently intervened in science as a foreign concept, not grounded in the dominant empiricism of modern biology. The uses of race in sciencewere therefore often disruptive and controversial; at times, science had to be retrofitted to accommodate race, and science in turn was often used to explain and justify race. This relationship was unstable in large part because race was about a phenomenon that could not be …

Faculty Publications

Purpose: A region of chromosome 22 which includes APOL1 and MYH9 genes was recently identified as a risk locus for non-diabetic forms of kidney disease, including idiopathic and HIV-associated focal segmental glomerular sclerosis and kidney disease clinically attributed to hypertension among African Americans. The purposes of the current study were, therefore, to examine the frequency of these variants and to determine whether they are associated with chronic kidney disease (CKD) among native Africans. Methods: To investigate the possible evidence of association between variants in these genes and non-diabetic CKD among West Africans, we performed a case/control analysis in a sample …

Genetic variants in intron 1 of the fat mass- and obesity-associated (FTO) gene have been consistently associated with body mass index (BMI) in Europeans. However, follow-up studies in African Americans (AA) have shown no support for some of the most consistently BMI-associated FTO index single nucleotide polymorphisms (SNPs). This is most likely explained by different race-specific linkage disequilibrium (LD) patterns and lower correlation overall in AA, which provides the opportunity to fine-map this region and narrow in on the functional variant. To comprehensively explore the 16q12.2/FTO locus and to search for second independent signals in the broader region, we fine-mapped …

The Nigerian Antihypertensive Adherence Trial: A Community-Based Randomized Trial, Adebowale Adeyemo, Bamidele O. Tayo, Amy Luke, Olugbenga Ogedegbe, Ramon Durazo-Arvizu, Richard S. Cooper

Faculty Publications

Background: Research in industrialized countries has demonstrated that a key factor limiting the control of hypertension is poor patient adherence and that the most successful interventions for long-term adherence employ multiple strategies. Very little data exist on this question in low-income countries, wherein medication-taking behavior may be less well developed. Method: We conducted a treatment adherence trial of 544 patients [mean age ∼63 years, mean blood pressure (BP) ∼168/92 mmHg] with previously untreated hypertension in urban and rural Nigeria. Eligible participants were randomized to one of two arms: clinic management only, or clinic management and home visits. Both interventions included …

Transport And Retention Of Nitrogen, Phosphorus And Carbon In North America's Largest River Swamp Basin, The Atchafalaya River Basin, Y. Jun Xu

Faculty Publications

Floodplains and river corridor wetlands may be effectively managed for reducing nutrients and carbon. However, our understanding is limited to the reduction potential of these natural riverine systems. This study utilized the long-term (1978-2004) river discharge and water quality records from an upriver and a downriver location of the Atchafalaya River to quantify the inflow, outflow, and inflow-outflow mass balance of total Kjeldahl nitrogen (TKN = organic nitrogen + ammonia nitrogen), nitrate + nitrite nitrogen (NO3 + NO2), total phosphorous (TP), and total organic carbon (TOC) through the largest river swamp basin in North America. The study found that, over …

Insulin Receptor-Independent Upregulation Of Cellular Glucose Uptake, R. Krishnapuram, H. Kirk-Ballard, E. J. Dhurandhar, O. Dubuisson, V. Messier, R. Rabasa-Lhoret, V. Hegde, S. Aggarwal, N. V. Dhurandhar

Faculty Publications

Background:Cellular glucose uptake can be enhanced by upregulating Ras signaling in either insulin-dependent or -independent manner. In presence of insulin and intact insulin signaling, Ras has a negligible role in glucose uptake. Conversely, when insulin signaling is impaired in obesity or diabetes, the insulin-independent Ras pathway may be valuable for enhancing glucose disposal. We previously reported that Ad36, a human adenovirus, enhances cellular glucose uptake by upregulating the Ras/Glut4 pathway. Here, we investigated if Ad36-upregulated Ras via the insulin-independent pathway, to enhance glucose uptake. Furthermore, uncontrolled upregulation of Ras is linked with oncogenic cell transformation, if the tumor-suppressor gene p53 …

Does Living By The Sword Mean Dying By The Sword?, Charles Chernor Jalloh

Faculty Publications

What do serial killer Ted Bundy, 9/11 terrorist Zacarias Moussaoui and alleged “Butcher of the Balkans” Slobodan Milošević have in common? Besides being accused of perpetrating some of the worst crimes known to law, they each insisted on representing themselves in court without the assistance of a lawyer. Not surprisingly, Bundy and Moussaoui were convicted. And although Milošević died just before trial judgment was rendered, it is widely speculated that he too would have been convicted by the International Criminal Tribunal for the former Yugoslavia. This article examines the right to self-representation in international criminal law. Using a comparative law …

China’S Human Rights Footprint In Africa, Timothy Webster Jan 2013

China’S Human Rights Footprint In Africa, Timothy Webster

Faculty Publications

A significant amount of recent scholarship and commentary accuses China of plundering the African continent, coddling its dictators, and flouting labor and environmental standards. This paper makes the counterintuitive claim that, despite irrefutable cases of abuse, China’s engagement with Africa has actually improved the human rights conditions of millions of Africans. First, it places China’s abuses in context, showing that they differ little from the abuses and patronage politics of the major Western powers. Second, it examines the evolution of international relations between China and various African countries, from the exportation of political revolution in the 1950s and 1960s, to …

Does Altitude Moderate The Impact Of Lithium On Suicide? A Spatial Analysis Of Austria, Marco Helbich, Victor Blüml, Michael Leitner, Nestor D. Kapusta Jan 2013

Does Altitude Moderate The Impact Of Lithium On Suicide? A Spatial Analysis Of Austria, Marco Helbich, Victor Blüml, Michael Leitner, Nestor D. Kapusta

Faculty Publications

Suicide, the tenth leading cause of death worldwide, is a complex phenomenon. Models aiming to explain the interaction of ambient variables such as socioeconomic factors, lithium content of drinking water and altitude are poorly developed. While controlling for several risk factors, this research bridges two different, but complementary research lines by investigating statistically the relationship on suicide mortality between lithium levels in drinking water in response to altitude above sea level. Besides regression models with main effects, a multiplicative interaction model between lithium and altitude has been developed providing estimates at the district-level for Austria where spatial autocorrelation was accounted …

Equality Between Adults And Children: Its Meaning, Implications, And Opposition, James G. Dwyer Jan 2013

Equality Between Adults And Children: Its Meaning, Implications, And Opposition, James G. Dwyer

Faculty Publications

Family law scholars have devoted much attention to equality among groups of adults and some attention to equality between groups of children. There has been little exploration, however, of the notion of equality between adults and children. In this Article, I first explain what it means at a basic, theoretical level to speak of such equality. I then identify some practical implications. Finally, I consider why there is great resistance to many practical implications of children's equality, even among those who would consider themselves advocates for child welfare.

MartinIzing Title I Of The Americans With Disabilities Act, Nicole Buonocore Porter Jan 2013

MartinIzing Title I Of The Americans With Disabilities Act, Nicole Buonocore Porter

Faculty Publications

Prior to the ADA Amendments Act of 2008, relatively few cases proceeded past the initial inquiry of whether the plaintiff was covered by the ADA. Consequently, the scope of an employer's obligation to provide a reasonable accommodation to an individual with a disability remains under-developed and under-theorized. Now that the Amendments have made it easier for plaintiffs to prove that they have a disability under the ADA, we can expect to see more courts struggling with many difficult reasonable accommodation issues. The current case law is chaotic, providing little guidance to employers and courts in determining whether an accommodation is …

The Quality Of Spouses’ Social Networks Contributes To Each Other’S Cardiovascular Risk, Wendy C. Birmingham, Bert N. Uchino, Timothy W. Smith, Mckenzie Carlisle, Kathleen C. Light

Faculty Publications

Objectives: Although the quality of one’s own social relationships has been related to cardiovascular morbidity and mortality, whether a partner’s social network quality can similarly influence one’s cardiovascular risk is unknown. In this study we tested whether the quality of a partner’s social networks influenced one’s own ambulatory blood pressure (ABP). Methods: The quality of 94 couples’ social networks was determined using a comprehensive model of relationships that separates out social ties that are sources of positivity(supportive), negativity (aversive), and both positivity and negativity (ambivalent). We then utilized statistical models (actor-partner analyses) that allowed us to separate out the links …

Academic Performance, Course Completion Rates, And Student Perception Of The Quality And Frequency Of Interaction In A Virtual High School, Abigail Hawkins, Charles R. Graham, Richard R. Sudweeks, Michael K. Barbour

Faculty Publications

This study examined the relationship between students’ perceptions of teacher– student interaction and academic performance at an asynchronous, self-paced, statewide virtual high school. Academic performance was measured by grade awarded and course completion. There were 2269 students who responded to an 18-item survey designed to measure student perceptions on the quality and frequency of teacher–student interaction. Quality of interaction was subdivided into three constructs representing feedback, procedural, and social interaction. A confirmatory factor analysis helped to establish the fit of the statistical model for teacher–student interaction. Hierarchical logistical regression indicates that an increase in the quality and frequency of interaction …

Caring In A Technology-Mediated Online High School Context, Andrea Velasquez, Charles R. Graham, Richard Osguthorpe

Faculty Publications

The objective of this study was to describe how caring is experienced in the technology-mediated context of the Open High School in Utah, an online charter high school. Two female teachers, two male students, and two female students were interviewed three times over 9 months regarding their experience of caring teacher–student interactions. Data were analyzed using interpretative phenomenological analysis (IPA). Discovered themes were then organized into three superordinate themes: engrossment, motivational displacement, and reciprocity. Results suggest not only that caring interactions are possible in the online context, but also that specific caring pedagogies can strengthen the teacher–student relationship online. Additionally, …

Perils And Profits: A Reexamination Of The Link Between Profitability And Safety In U.S. Aviation, Peter M. Madsen Jan 2013

Perils And Profits: A Reexamination Of The Link Between Profitability And Safety In U.S. Aviation, Peter M. Madsen

Faculty Publications

In many industries, for-profit business organizations make decisions that critically impact the safety of their employees and the public. Managers in such organizations often argue that there is no trade-off between profitability and safety because “safety is good business.” However, prior studies examining the profitability–safety relationship report inconsistent and conflicting results. In the present study, the author reexamines this issue, building on insights into managerial risk taking from the behavioral theory of the firm and hypothesizing that the slope of the profitability–safety relationship reaches an inflection point at the organizational profitability aspiration. Using data from the U.S. airline industry, the …
