Intraneuronal Β-Amyloid Accumulation: Aging Hiv-1 Human And Hiv-1 Transgenic Rat Brain, Hailong Li, Kristen A. Mclaurin, Charles F. Mactutus, Benjamin Linkins, Wenfei Huang, Sulie L. Chang, Rosemarie M. Booze

Faculty Publications

The prevalence of HIV-1 associated neurocognitive disorders (HAND) is significantly greater in older, relative to younger, HIV-1 seropositive individuals; the neural pathogenesis of HAND in older HIV-1 seropositive individuals, however, remains elusive. To address this knowledge gap, abnormal protein aggregates (i.e., β-amyloid) were investigated in the brains of aging (>12 months of age) HIV-1 transgenic (Tg) rats. In aging HIV-1 Tg rats, double immunohistochemistry staining revealed abnormal intraneuronal β-amyloid accumulation in the prefrontal cortex (PFC) and hippocampus, relative to F344/N control rats. Notably, in HIV-1 Tg animals, increased β-amyloid accumulation occurred in the absence of any genotypic changes in …

Reporting Verb Variation Across Disciplines: An Academic Corpus Study, Grant Eckstein, Jacob D. Rawlins, Hannah Taylor, Haley Briggs, Andrea Candland, Elizabeth Hanks, Sarah Hill

Faculty Publications

Reporting verbs are used in academic writing to establish authorial voice when referencing previous research. Although the practice is widespread, inexperienced academic writers and second-language learners may struggle to select appropriate reporting verbs within their given discipline or may overuse them in ways that signal outsider status. The present study explores the distribution of reporting verbs across six disciplines in a corpus containing 270 academic research background sections (introduction and literature review). The results illustrate that disciplines vary widely in the number and type of reporting verbs used. While common reporting verbs across disciplines include argue, examine, report …

In Their Own Words: Perspectives On Collection Weeding From Library Employees And Teaching Faculty, Dan Broadbent, Megan Frost, Gregory M. Nelson, David Pixton

Faculty Publications

Following a Science and Engineering collection weeding project of over 350,000 print items, our research team conducted interviews with 20 library employees and 19 teaching faculty involved in the project. The purpose of the interviews was to assess the interviewees’ perspectives and feelings relating to the time required to complete the project, inter- and intra- library communication, the decision-making processes, and their personal assessment of the costs and benefits of the project. The interviewees also offered their views of the overall project’s successes and areas for improvement. Drawing from a qualitative analysis of the interviews, we provide guidance for other …

Unrestricted Factor Analysis: A Powerful Alternative To Confirmatory Factor Analysis, Jan-Benedict E.M. Steenkamp, Alberto Maydeu-Olivares

Faculty Publications

The gold standard for modeling multiple indicator measurement data is confirmatory factor analysis (CFA), which has many statistical advantages over traditional exploratory factor analysis (EFA). In most CFA applications, items are assumed to be pure indicators of the construct they intend to measure. However, despite our best efforts, this is often not the case. Cross-loadings incorrectly set to zero can only be expressed through the correlations between the factors, leading to biased factor correlations and to biased structural (regression) parameter estimates. This article introduces a third approach, which has emerged in the psychometric literature, viz., unrestricted factor analysis (UFA). UFA …

We Will Rise No Matter What': Community Perspectives Of Disaster Resilience Following Hurricanes Irma And Maria In Puerto Rico, Elizabeth L. Petrun Sayers, Kathryn E. Anthony, Ashlyn Tom, Alice Y. Kim, Courtney Armstrong

Faculty Publications

Category 4 Hurricane Maria made landfall in Puerto Rico on 20 September 2017 and ploughed across the territory with sustained winds of 155 mph. Just two weeks earlier, category 5 Hurricane Irma had struck the island already damaging critical infrastructure making Hurricane Maria even more devasting. The hurricanes caused catastrophic damage, resulting in the largest and longest response to a domestic disaster in the history of the United States. This paper explores the recovery process in Puerto Rico using a community resilience lens. The study examines narratives, the media environment, trusted sources, and information preferences following the crisis. Community workshops, …

Cataloging Conundrums: Challenging Items That Have Crossed Our Desks, Rebecca A. Wiederhold, Sharolyn Swenson, Kjerste Christensen, Jessie Louise Christensen

Faculty Publications

Some of the most interesting items that cross the cataloger’s desk present difficult cataloging challenges. When cataloging a collection of suspected forgeries, how do you determine the “publication” date for faked documents? Which cataloging workform do you use for a LEGO model of the Salt Lake Temple? Is it a kit? A game? A sculpture? In this session, we will share examples of unique items we’ve cataloged and demonstrate how to effectively solve the questions that come up when trying to help patrons discover exactly what they’re looking for.

Cross-Modal Perception Of Identity By Sound And Taste In Bottlenose Dolphins, Jason N. Bruck, Sam F. Walmsley, Vincent M. Janik

Faculty Publications

While studies have demonstrated concept formation in animals, only humans are known to label concepts to use them in mental simulations or predictions. To investigate whether other animals use labels comparably, we studied cross-modal, individual recognition in bottlenose dolphins (Tursiops truncatus) that use signature whistles as labels for conspecifics in their own communication. First, we tested whether dolphins could use gustatory stimuli and found that they could distinguish between water and urine samples, as well as between urine from familiar and unfamiliar individuals. Then, we paired playbacks of signature whistles of known animals with urine samples from either the same …

Land Rich, Cash Poor: Hispanic Subsistence Agri-Culture On Acequia Farms Of Northern New Mexico, 1880-1950s, José A. Rivera Ph.D.

Faculty Publications

Acequia-based agriculture in Hispanic northern New Mexico originated with the arrival of settlers from the central valley of Mexico in the late sixteenth century and later following the Camino Real into the upper Río Grande and its tributaries. The high desert environment required irrigation for food production and survival. Land parcels in the rural villages of northern New Mexico were small, and crop yields were limited to home consumption on a subsistence basis, an economy that lasted well into the territorial period and statehood of New Mexico. Despite a wage economy introduced with the arrival of the railroad around 1880 …

Composite Style Pixel And Point Convolution-Based Deep Fusion Neural Network Architecture For The Semantic Segmentation Of Hyperspectral And Lidar Data, Kevin T. Decker, Brett J. Borghetti

Faculty Publications

Multimodal hyperspectral and lidar data sets provide complementary spectral and structural data. Joint processing and exploitation to produce semantically labeled pixel maps through semantic segmentation has proven useful for a variety of decision tasks. In this work, we identify two areas of improvement over previous approaches and present a proof of concept network implementing these improvements. First, rather than using a late fusion style architecture as in prior work, our approach implements a composite style fusion architecture to allow for the simultaneous generation of multimodal features and the learning of fused features during encoding. Second, our approach processes the higher …

Predictors Of Therapy Response In Chronic Aphasia: Building A Foundation For Personalized Aphasia Therapy, Sigfus Kristinsson, Dirk B. Den Ouden, Chris Rorden, Roger Newman-Norlund

Faculty Publications

Chronic aphasia, a devastating impairment of language, affects up to a third of stroke survivors. Speech and language therapy has consistently been shown to improve language function in prior clinical trials, but few clinicially applicable predictors of individual therapy response have been identified to date. Consequently, clinicians struggle substantially with prognostication in the clinical management of aphasia. A rising prevalence of aphasia, in particular in younger populations, has emphasized the increasing demand for a personalized approach to aphasia therapy, that is, therapy aimed at maximizing language recovery of each individual with reference to evidence-based clinical recommendations. In this narrative review, …

Neural Correlates Of Impaired Vocal Feedback Control In Post-Stroke Aphasia, Roozbeh Behroozmand, Leonardo Bonilha, Chris Rorden, Gregory Hickok, Julius Fridriksson

Faculty Publications

We used left-hemisphere stroke as a model to examine how damage to sensorimotor brain networks impairs vocal auditory feedback processing and control. Individuals with post-stroke aphasia and matched neurotypical control subjects vocalized speech vowel sounds and listened to the playback of their self-produced vocalizations under normal (NAF) and pitch-shifted altered auditory feedback (AAF) while their brain activity was recorded using electroencephalography (EEG) signals. Event-related potentials (ERPs) were utilized as a neural index to probe the effect of vocal production on auditory feedback processing with high temporal resolution, while lesion data in the stroke group was used to determine how brain …

Canonical Sentence Processing And The Inferior Frontal Cortex: Is There A Connection?, Nicholas Riccardi, Chris Rorden, Julius Fridriksson, Rutvik H. Desai

Faculty Publications

The role of left inferior frontal cortex (LIFC) in canonical sentence comprehension is controversial. Many studies have found involvement of LIFC in sentence production or complex sentence comprehension, but negative or mixed results are often found in comprehension of simple or canonical sentences. We used voxel-, region-, and connectivity-based lesion symptom mapping (VLSM, RLSM, CLSM) in left-hemisphere chronic stroke survivors to investigate canonical sentence comprehension while controlling for lexical-semantic, executive, and phonological processes. We investigated how damage and disrupted white matter connectivity of LIFC and two other language-related regions, the left anterior temporal lobe (LATL) and posterior temporal-inferior parietal area …

Thalamic Shape Abnormalities Differentially Relate To Cognitive Performance In Early-Onset And Adult-Onset Schizophrenia, Derin J. Cobia, Chaz Rich, Matthew J. Smith, Pedro Engel Gonzalez, Will Cronenwett, John G. Csernansky, Lei Wang

Faculty Publications

Early-onset schizophrenia (EOS) shares many biological and clinical features with adult-onset schizophrenia (AOS), but may represent a unique subgroup with greater susceptibility for disease onset and worsened symptomatology and progression, which could potentially derive from exaggerated neurodevelopmental abnormalities. Neurobiological explanations of schizophrenia have emphasized the involvement of deep-brain structures, particularly alterations of the thalamus, which have been linked to core features of the disorder. The aim of this study was to compare thalamic shape abnormalities between EOS and AOS subjects and determine whether unique behavioral profiles related to these differences. It was hypothesized abnormal thalamic shape would be observed in …

Maternal Depression Moderated By Family Resources When Children Have Developmental Disabilities., Timothy B. Smith, Terisa P. Gabrielsen

Faculty Publications

Children with developmental disabilities require extensive parental involvement in intervention, but parents with depression may be less able to intervene effectively. We examined prevalence of depression symptoms and predictors among 131 mothers of children with disabilities enrolled in early childhood special education. Participants completed several self-report measures of depression and child and family functioning. Children were directly evaluated using the Battelle Developmental Inventory. One year later, 68 mothers repeated self-report measures. Participants (30%) reported elevated depression symptoms across time. Depression scores were correlated with parental stress and family resources. An interaction between higher maternal depression and higher child functioning with …

The Eschatological Hope Scale: Construct Development And Measurement Of Theistic Eschatological Hope, Charlotte Vanoyen-Witvliet, M. Elizabeth Lewis Hall, Julie J. Exline, David C. Wang, Lindsey M. Root Luna, Daryl R. Van Tongeren, David G. Myers, Alexis D. Abernethy, John D. Witvliet

Faculty Publications

This study aimed to expand psychological research on hope by contributing a construct and scale to measure central dimensions of theistic eschatological hope derived from Christian scriptures. Eschatological hope was conceptualized as the anticipation that God will make all things new, raising people to everlasting life with God in joyful celebration, including people from every culture and nation, ending all personal pain and suffering, eliminating all societal evil and harm, and bringing reconciliation and healing to all of creation. We developed the Eschatological Hope Scale with three studies (N = 1,466). Exploratory and confirmatory factor analyses supported the single-factor structure …

A Resilience-Based Intervention To Mitigate The Effect Of Hiv-Related Stigma: Protocol For A Stepped Wedge Cluster Randomized Trial, Xiaoming Li, Shan Qiao, Xueying Yang, Sayward Harrison, Cheuk Chi Tam, Zhiyong Shen, Yuejiao Zhou

Faculty Publications

Background: Despite decades of global efforts to tackle HIV-related stigma, previous interventions designed to reduce stigma have had limited effects that were typically in the small- to-moderate range. The knowledge gaps and challenges for combating HIV-related stigma are rooted both in the complexity of the stigma and in the limitations of current conceptualizations of stigma reduction efforts. Recent research has shown the promise of resilience-based approaches that focus on the development of strengths, competencies, resources, and capacities of people living with HIV (PLWH) and their key supporting systems (e.g., family members and healthcare providers) to prevent, reduce, and mitigate the …

Structural Problems Of Latin American Cities 450 Years After Caracas’ Foundation, Fabio Capra-Ribeiro

Faculty Publications

Latin American cities face many problems that compromise them from different angles such as lack of infrastructure, government fragmentation, and environmental degradation. At the same time, each city tries to come up with its own solutions, but there are so many difficulties that in many cases it is difficult to keep attention and efforts focused on all these directions. For these reasons, this research aims to define some of the most common problems faced by cities in Latin America. Disseminating these similarities could help to face those problems, since, if local governments recognize that they face the same situations as …

Increasing Patron’S Outreach And Engagement Through Relationship Marketing: A Case Study, Margaret Adeogun

This requirement has become more prominent among libraries serving a highly diverse user community, particularly in a more racially and ethnically diverse campus. Adopting a marketing model that cultivates more meaningful long-term relationships with customers ensures long-term satisfaction and loyalty to the library brand. Using marketing and promotional examples from the James White Library, this article addresses the academic library’s relationship marketing strategy in an increasingly multicultural higher education environment.

Global Gnss-Ro Electron Density In The Lower Ionosphere, Dong L. Wu, Daniel J. Emmons Ii, Nimalan Swarnalingam

Faculty Publications

Lack of instrument sensitivity to low electron density (N_e) concentration makes it difficult to measure sharp N_e vertical gradients (four orders of magnitude over 30 km) in the D/E-region. A robust algorithm is developed to retrieve global D/E-region N_e from the high-rate GNSS radio occultation (RO) data, to improve spatiotemporal coverage using recent SmallSat/CubeSat constellations. The new algorithm removes F-region contributions in the RO excess phase profile by fitting a linear function to the data below the D-region. The new GNSS-RO observations reveal many interesting features in the diurnal, seasonal, solar-cycle, and magnetic-field-dependent variations in the …
