What Can Parents Do? Examining The Role Of Parental Support On The Negative Relationship Between Racial Discrimination, Depression, And Drug Use Among African American Youth, Tamika C. B. Zapolski, Sycarah Fisher, Wei-Wen Hsu, Jessica Barnes Jul 2016

What Can Parents Do? Examining The Role Of Parental Support On The Negative Relationship Between Racial Discrimination, Depression, And Drug Use Among African American Youth, Tamika C. B. Zapolski, Sycarah Fisher, Wei-Wen Hsu, Jessica Barnes

Educational, School, and Counseling Psychology Faculty Publications

African American youth who experience racial discrimination are at heightened risk to use drugs as a coping response to distress. Based on the buffer-stress hypothesis, we proposed that parental support would attenuate this effect. Participants were 1,521 African American youth between 4th and 12th grade. As hypothesized, a mediation pathway was observed among racial discrimination, depression symptoms, and drug use. This effect was observed for both genders, although the pathway was partially mediated for males. In addition, as hypothesized, parental support buffered the negative effect of depression symptomatology on drug use as a consequence of discrimination. Our findings highlight the …

Pruning Or Tuning? Maturational Profiles Of Face Specialization During Typical Development, Xun Zhu, Ramesh S. Bhatt, Jane E. Joseph Jun 2016

Pruning Or Tuning? Maturational Profiles Of Face Specialization During Typical Development, Xun Zhu, Ramesh S. Bhatt, Jane E. Joseph

Psychology Faculty Publications

Introduction: Face processing undergoes significant developmental change with age. Two kinds of developmental changes in face specialization were examined in this study: specialized maturation, or the continued tuning of a region to faces but little change in the tuning to other categories; and competitive interactions, or the continued tuning to faces accompanied by decreased tuning to nonfaces (i.e., pruning). Methods: Using fMRI, in regions where adults showed a face preference, a face- and object-specialization index were computed for younger children (5-8 years), older children (9-12 years) and adults (18-45 years). The specialization index was scaled to each subject's maximum activation …


Starting Over: Coding To Work With Alma After Voyager, Kathryn Lybarger Jun 2016

Starting Over: Coding To Work With Alma After Voyager, Kathryn Lybarger

Library Presentations

When the University of Kentucky was a Voyager library, I wrote a variety of tools to support our processes, ranging from tiny one-line macros to larger software packages. Now that we've migrated to Alma/Primo, everything has changed! Many of the ways I extended Voyager are part of Alma by default, and Alma's community (and available APIs) encourage even further development. In this presentation, I will describe some differences between the two systems, how they affected the types of support tools I wanted, and the ways I was able to create them.

Library Presentations

Alma offers some advantages to Acquisitions particularly for managing electronic workflows and communicating with vendors. However, transitioning from Voyager to Alma and learning Alma’s nuances was challenging as we reworked workflows.


Rethinking Social Change: The Promises Of Web 2.0 For The Marginalized, David Nemer Jun 2016

Rethinking Social Change: The Promises Of Web 2.0 For The Marginalized, David Nemer

Information Science Faculty Publications

This paper focuses on the uses of Web 2.0 platforms by residents of favelas, urban slums in Brazil, in order to expand our understanding of what Web 2.0 can and cannot do in terms of social change. To explore this problem space, I draw on a 10-month ethnography in the favelas of Vitória, Brazil to study slum residents’ Web 2.0 practices and engagements. I show how Web 2.0 afforded favela residents the ability to protest and cross social boundaries, but when that happened they faced something much stronger: social exclusion, police brutality against the blacks and poor, and limited civic …

The 21-gene Recurrence Score assay is validated to predict recurrence risk and chemotherapy benefit in hormone-receptor-positive (HR+) invasive breast cancer. To determine prospective breast-cancer-specific mortality (BCSM) outcomes by baseline Recurrence Score results and clinical covariates, the National Cancer Institute collaborated with Genomic Health and 14 population-based registries in the the Surveillance, Epidemiology, and End Results (SEER) Program to electronically supplement cancer surveillance data with Recurrence Score results. The prespecified primary analysis cohort was 40–84 years of age, and had node-negative, HR+, HER2-negative, nonmetastatic disease diagnosed between January 2004 and December 2011 in the entire SEER population, and Recurrence Score results …

Sanders-Brown Center on Aging Faculty Publications

To determine if proton magnetic resonance spectroscopy (1H-MRS) detect differences in dementia status in adults with Down syndrome (DS), we used 1H-MRS to measure neuronal and glial metabolites in the posterior cingulate cortex in 22 adults with DS and in 15 age- and gender-matched healthy controls. We evaluated associations between 1H-MRS results and cognition among DS participants. Neuronal biomarkers, including N-acetylaspartate (NAA) and glutamate-glutamine complex (Glx), were significantly lower in DS patients with Alzheimer's should probably be changed to Alzheimer (without ' or s) through ms as per the new naming standard disease (DSAD) when …


Using The I-Learn Model For Information Literacy Instruction, Stacey Greenwell Jun 2016

Using The I-Learn Model For Information Literacy Instruction, Stacey Greenwell

Library Faculty and Staff Publications

With the increasing availability of information and the importance of lifelong information literacy (IL) skills, instructional designers, school media specialists, and librarians need to determine how to best design IL teaching in order to help students locate, evaluate, and use information more effectively. This paper describes the first experimental research study conducted to determine how teaching designed using the I-LEARN model could increase student understanding and application of IL concepts and offer recommendations for future implementations of the model. The experimental study described in this article examined whether IL skills teaching designed using the I-LEARN model increased student understanding and …

Learning From Texts: Activation Of Information From Previous Texts During Reading, Katinka Beker, Dietsje Jolles, Robert F. Lorch Jr., Paul Van Den Broek Jun 2016

Learning From Texts: Activation Of Information From Previous Texts During Reading, Katinka Beker, Dietsje Jolles, Robert F. Lorch Jr., Paul Van Den Broek

Psychology Faculty Publications

Learning often involves integration of information from multiple texts. The aim of the current study was to determine whether relevant information from previously read texts is spontaneously activated during reading, allowing for integration between texts (experiment 1 and 2), and whether this process is related to the representation of the texts (experiment 2). In both experiments, texts with inconsistent target sentences were preceded by texts that either did or did not contain explanations that resolved the inconsistencies. In experiment 1, the reading times of the target sentences introducing inconsistencies were faster if the preceding text contained an explanation for the …


Are Consumers Willing To Pay More For Sustainable Products? A Study Of Eco-Labeled Tuna Steak, Guzhen Zhou, Wuyang Hu, Wenchao Huang May 2016

Are Consumers Willing To Pay More For Sustainable Products? A Study Of Eco-Labeled Tuna Steak, Guzhen Zhou, Wuyang Hu, Wenchao Huang

Agricultural Economics Faculty Publications

A high demand for seafood leads to overfishing, harms the long-term health of seafood stocks, and threatens environmental sustainability in oceans. Sustainability certification is one of the major sustainability movements and is known as eco-labeling. For instance, in the tuna industry, leading tuna brands have committed to protecting sea turtles by allowing the tracing of the source of their tuna “from catch to can.” This paper relies on an Internet survey on consumers from Kentucky conducted in July 2010. The survey investigates household-level tuna steak (sashimi grade) consumption and examines consumer preferences for eco-labeling (“Certified Turtle Safe” (CTS) in this …

Sanders-Brown Center on Aging Faculty Publications

Dendritic mislocalization of microtubule associated protein tau is a hallmark of tauopathies, but the role of dendritic tau is unknown. We now report that tau interacts with the RNA-binding protein (RBP) TIA1 in brain tissue, and we present the brain-protein interactome network for TIA1. Analysis of the TIA1 interactome in brain tissue from wild-type (WT) and tau knockout mice demonstrates that tau is required for normal interactions of TIA1 with proteins linked to RNA metabolism, including ribosomal proteins and RBPs. Expression studies show that tau regulates the distribution of TIA1, and tau accelerates stress granule (SG) formation. Conversely, TIA1 knockdown …


Public Health Spending And Its Contributions To The Total Spend On Health, Glen P. Mays May 2016

Public Health Spending And Its Contributions To The Total Spend On Health, Glen P. Mays

Health Management and Policy Presentations

This presentation provides an overview of recent research on governmental public health expenditures and their interaction with medical spending, carried out through the Robert Wood Johnson Foundation supported initiatives on Public Health Services and Systems Research (PHSSR) and the new Systems for Action research program. This work illustrates the value of tracking resource use across multiple sectors that influence health and well-being in American communities. As such, this work can inform the ongoing dialogue about methodologies for summarizing total health spending for the U.S. and for state and local areas.


Plasma Neuronal Exosomal Levels Of Alzheimer's Disease Biomarkers In Normal Aging, Erin L. Abner, Gregory A. Jicha, Leslie M. Shaw, John Q. Trojanowski, Edward J. Goetzl May 2016

Plasma Neuronal Exosomal Levels Of Alzheimer's Disease Biomarkers In Normal Aging, Erin L. Abner, Gregory A. Jicha, Leslie M. Shaw, John Q. Trojanowski, Edward J. Goetzl

Sanders-Brown Center on Aging Faculty Publications

Plasma neuronal exosomal levels of pathogenic Alzheimer's disease (AD) proteins, cellular survival factors, and lysosomal proteins distinguish AD patients from control subjects, but changes in these exosomal proteins associated with normal aging have not been described for cognitively intact subjects. Plasma neuronal exosomal levels of P-T181-tau, P-S396-tau, Aβ1-42, cathepsin D, repressor element 1-silencing transcription factor, and neurogranin were quantified longitudinally in cognitively intact older adults using two samples collected at 3- to 11-year intervals. Except for P-S396-tau, exosomal protein levels changed significantly with aging, but were largely outside the range observed in AD patients.


Labor Market Returns To The Ged Using Regression Discontinuity Analysis, Christopher Jepsen, Peter Mueser, Kenneth R. Troske May 2016

Labor Market Returns To The Ged Using Regression Discontinuity Analysis, Christopher Jepsen, Peter Mueser, Kenneth R. Troske

Economics Faculty Publications

We evaluate returns to General Educational Development (GED) certification for high school dropouts using state administrative data. We apply a fuzzy regression discontinuity method to account for test takers retaking the test. For women we find that GED certification has no statistically significant effect on either employment or earnings. For men we find a significant increase in earnings in the second year after taking the test but no impact in subsequent years. GED certification increases postsecondary school enrollment by 4–8 percentage points. Our results differ from regression discontinuity approaches that fail to account for test retaking.


Transnational Ties Within Azorean Multigenerational Kinship Groups: Multi-Connectedness And Icts, Ana Gherghel, Josiane Le Gall May 2016

Transnational Ties Within Azorean Multigenerational Kinship Groups: Multi-Connectedness And Icts, Ana Gherghel, Josiane Le Gall

disClosure: A Journal of Social Theory

This article analyzes the influence of ICTs use on transnational connections and on their perpetuation over time within multigenerational kinship groups dispersed in several countries. Evidence from a multi-sited ethnographic research dedicated to migration from the Azores archipelago (Portugal) to the province of Quebec (Canada) provides information about factors explaining transnational practice over several decades. Our data indicate an overall intensification of transnational contacts due to increasing accessibility of new technologies. However, this process takes place in a family environment characterized by multi-connectedness, a capacity to maintain multiple active ties with siblings living in various countries and using multiple modalities. …


Beyond Metropolises: Hybridity In A Transnational Context, Raihan Sharif May 2016

Beyond Metropolises: Hybridity In A Transnational Context, Raihan Sharif

disClosure: A Journal of Social Theory

Beyond metropolises and within transnational contexts, investigating hybridity discourses is long overdue. This article argues that the epistemic violence embedded in such discourse has grave implications for the very impoverished nations and peoples with whom it claims solidarity and that, because this discourse is trendy in academia, its service to neoliberal capitalism is both easy to miss and important to expose. Interstices of postcolonial hybridity discourses, development discourses, and environmental justice discourses—dominant versions of which are segregated from contextual issues—as produced in Western academia and exported to third world countries for appropriation as developmental efforts—reveal epistemic violence, the manipulation of …


Speaking In Tongues: Language And National Belonging In Globalizing Europe, Uli Linke May 2016

Speaking In Tongues: Language And National Belonging In Globalizing Europe, Uli Linke

disClosure: A Journal of Social Theory

In contemporary Europe, the problematic concept of the nation has been recuperated to fasten subjects to political space. Under the impact of globalization, marked by increasing rates of human mobility and concurrent security concerns, European Union states have begun to push for cohesive measures to reclaim their national sovereignty. Revised immigration laws and refugee policies are publicly supported, presumably to keep the nation safe. At the same time, European countries advocate for openness and permeable borders to attract foreign capital investment. In the national interior, Islamophobia and anti-immigrant sentiments have come to coexist with the outward dissemination of promotional images …


The Tnfα-Transgenic Rat: Hippocampal Synaptic Integrity, Cognition, Function, And Post-Ischemic Cell Loss, L. Creed Pettigrew, Richard J. Kryscio, Christopher M. Norris May 2016

The Tnfα-Transgenic Rat: Hippocampal Synaptic Integrity, Cognition, Function, And Post-Ischemic Cell Loss, L. Creed Pettigrew, Richard J. Kryscio, Christopher M. Norris

Sanders-Brown Center on Aging Faculty Publications

The cytokine, tumor necrosis factor α (TNFα), is a key regulator of neuroinflammation linked to numerous neurodegenerative conditions and diseases. The present study used transgenic rats that overexpress a murine TNFα gene, under the control of its own promoter, to investigate the impact of chronically elevated TNFα on hippocampal synaptic function. Neuronal viability and cognitive recovery in TNFα Tg rats were also determined following an ischemic insult arising from reversible middle cerebral artery occlusion (MCAO). Basal CA3-CA1 synaptic strength, recorded in acute brain slices, was not significantly different between eight-week-old TNFα Tg rats and non-Tg rats. In contrast, slices from …

African American Female Offender's Use Of Alternative And Traditional Health Services After Re-Entry: Examining The Behavioral Model For Vulnerable Populations, Carrie B. Oser, Amanda M. Bunting, Erin L. Pullen, Danelle Stevens-Watkins May 2016

African American Female Offender's Use Of Alternative And Traditional Health Services After Re-Entry: Examining The Behavioral Model For Vulnerable Populations, Carrie B. Oser, Amanda M. Bunting, Erin L. Pullen, Danelle Stevens-Watkins

Sociology Faculty Publications

This is the first known study to use the Gelberg-Andersen Behavioral Model for Vulnerable Populations to predict African American women's use of three types of health services (alternative, hospitalization, and ambulatory) in the 18 months after release from prison. In the multivariate models, the most robust predictors of all three types of service utilization were in the vulnerable theoretical domains. Alternative health services were predicted by ethnic community membership, higher religiosity, and HIV/HCV. Hospitalizations were predicted by the lack of barriers to health care and disability. Ambulatory office visits were predicted by more experiences of gendered racism, a greater number …


Qualitative Interviews: A Methodological Discussion Of The Interviewer And Respondent Contexts, Shannon M. Oltmann May 2016

Qualitative Interviews: A Methodological Discussion Of The Interviewer And Respondent Contexts, Shannon M. Oltmann

Information Science Faculty Publications

Interviews are a staple method used in qualitative research. Many authors hold face-to-face interviews to be the gold standard, or the assumed best mode in which to conduct interviews. However, a large number of research projects are based on conducting interviews via telephone. While some scholars have addressed the advantages and disadvantages of using telephones to conduct interviews, this work is scattered across multiple disciplines and lacks a cohesive, comprehensive framework. The current article seeks to rectify this gap in the literature, by explicitly developing the constructs of the interviewer context and the respondent context. By examining key components in …

Mapping Temperate Vegetation Climate Adaptation Variability Using Normalized Land Surface Phenology, Liang Liang, Mark D. Schwartz, Xiaoyang Zhang Apr 2016

Mapping Temperate Vegetation Climate Adaptation Variability Using Normalized Land Surface Phenology, Liang Liang, Mark D. Schwartz, Xiaoyang Zhang

Geography Faculty Publications

Climate influences geographic differences of vegetation phenology through both contemporary and historical variability. The latter effect is embodied in vegetation heterogeneity underlain by spatially varied genotype and species compositions tied to climatic adaptation. Such long-term climatic effects are difficult to map and therefore often neglected in evaluating spatially explicit phenological responses to climate change. In this study we demonstrate a way to indirectly infer the portion of land surface phenology variation that is potentially contributed by underlying genotypic differences across space. The method undertaken normalized remotely sensed vegetation start-of-season (or greenup onset) with a cloned plants-based phenological model. As the …

Understanding The Value Of Multi-Sector Partnerships To Improve Population Health, Glen P. Mays Apr 2016

Understanding The Value Of Multi-Sector Partnerships To Improve Population Health, Glen P. Mays

Health Management and Policy Presentations

We review recent research concerning multi-sectoral partnerships aimed at improving health status on a population-wide basis, with a particular focus on implementation strategies and on health and economic impact. While still preliminary and emerging, research indicates that large health benefits are possible through collective actions that engage the medical, public health, and social sectors. Mechanisms for aligning incentives, dividing responsibilities equitably, and measuring progress regularly appear critical to success.
