Leveraging Multimedia To Advance Science By Disseminating A Greater Variety Of Scholarly Contributions In More Accessible Formats, James Gaskin, Paul Benjamin Lowry, David Hull Jan 2016

Leveraging Multimedia To Advance Science By Disseminating A Greater Variety Of Scholarly Contributions In More Accessible Formats, James Gaskin, Paul Benjamin Lowry, David Hull

Faculty Publications

For the welfare of the scientific community, we are intentionally rocking the boat with regards to the way we conduct, recognize, and disseminate scholarly contributions. As a scientific community, we are doing ourselves a great disservice by ignoring the insights, artifacts, discoveries, and conversations which naturally occur in the scientific process of advancing knowledge, but which do not fit into the very narrowly defined form of print-style articles. By failing to recognize, reward, and publish the wide variety of scholarly contributions that are not well suited to the print-style article, we hinder scientific progress, devalue important and necessary contributions to …

Short Term Memory Of Magnetic Resonance Imaging Technologists, Samuel Maldonado Jan 2016

Short Term Memory Of Magnetic Resonance Imaging Technologists, Samuel Maldonado

Walden Dissertations and Doctoral Studies

This study examined the short term memory (STM) difference of magnetic resonance imaging (MRI) technologists versus non-MRI technologists. Human and animal studies have indicated that residual magnetic fields have caused changes within the cerebral structure. Research on residual magnetic fields and their effect on STM is still at its infancy. A quasi-experimental design was used to determine if any significant difference existed between the STM of MRI technologists (n = x) and a control population sample (n = x). The STM of both groups was assessed with the use of the Rivermead Behavioural Memory Test-Third Edition. Solicitation of the participants …

Perceptions Of Stroke Risks Among West African Male Immigrants In San Diego, Lawrence Agi Jan 2016

Perceptions Of Stroke Risks Among West African Male Immigrants In San Diego, Lawrence Agi

Walden Dissertations and Doctoral Studies

The incidence and knowledge of the risk factors of stroke across ethnic groups in the United States have been examined in multiple studies. However, it is not well known if the foreign-born African immigrants who constitute about 4% of the U.S. immigrant population are at a higher risk of the incidence of stroke than are other nonimmigrant population in the U. S. This ethnographic study explored the perceptions of Anglophone African male immigrants residing in San Diego on the risk factors of stroke. The theoretical framework for this study included the health belief model and the health promotion model. Data …

Incidence And Factors Associated With Nonalcoholic Fatty Liver Disease Among Patients With Rheumatoid Arthritis, Ani K. John Jan 2016

Incidence And Factors Associated With Nonalcoholic Fatty Liver Disease Among Patients With Rheumatoid Arthritis, Ani K. John

Walden Dissertations and Doctoral Studies

Nonalcoholic fatty liver disease (NAFLD) has become one of the most common hepatic diseases worldwide, making the diagnosis and management of NAFLD an emerging public health issue. Theories associated with NAFLD surmise that inflammation may be the root cause, along with the complex interplay of other chronic conditions such as obesity, metabolic syndrome, diabetes, dyslipidemia, and cardiovascular disease (CVD). It is unknown if other inflammatory conditions such as rheumatoid arthritis (RA), along with the use of methotrexate (MTX), might confer increased risk for NAFLD. Longitudinal data collected from a retrospective cohort of 17,481 adult RA patients in the United States …

Teachers' Perceptions Of Manipulatives During Middle School Math Instruction, Angela L. Vizzi Jan 2016

Teachers' Perceptions Of Manipulatives During Middle School Math Instruction, Angela L. Vizzi

Walden Dissertations and Doctoral Studies

In a Colorado school district, school personnel and parents were concerned that middle school math proficiency levels were low for 2011-2014 and math teachers were not using manipulatives in their classes to increase math performance. The district's math coordinator did not foresee providing specific professional development (PD) for math manipulative use to address these concerns. Without this PD, math teachers may be ill-quipped to teach math concepts when using manipulatives, which, in turn, could lead to further poor math performance. The purpose of this qualitative bounded collective case study was to explore middle school teachers' perceptions of PD and perceived …

There Is More To Gesture Than Meets The Eye: Visual Attention To Gesture’S Referents Cannot Account For Its Facilitative Effects During Math Instruction, Miriam A. Novack, Elizabeth M. Wakefield, Eliza L. Congdon, Steven Franconeri, Susan Goldin-Meadow Jan 2016

There Is More To Gesture Than Meets The Eye: Visual Attention To Gesture’S Referents Cannot Account For Its Facilitative Effects During Math Instruction, Miriam A. Novack, Elizabeth M. Wakefield, Eliza L. Congdon, Steven Franconeri, Susan Goldin-Meadow

Psychology: Faculty Publications and Other Works

Teaching a new concept with gestures – hand movements that accompany speech – facilitates learning above-and-beyond instruction through speech alone (e.g., Singer & GoldinMeadow, 2005). However, the mechanisms underlying this phenomenon are still being explored. Here, we use eye tracking to explore one mechanism – gesture’s ability to direct visual attention. We examine how children allocate their visual attention during a mathematical equivalence lesson that either contains gesture or does not. We show that gesture instruction improves posttest performance, and additionally that gesture does change how children visually attend to instruction: children look more to the problem being explained, and …

Comparing Process-Based And Constraint-Based Approaches For Modeling Macroecological Patterns, Xiao Xiao Jan 2016

Comparing Process-Based And Constraint-Based Approaches For Modeling Macroecological Patterns, Xiao Xiao

Biology Faculty Publications

Ecological patterns arise from the interplay of many different processes, and yet the emergence of consistent phenomena across a diverse range of ecological systems suggests that many patterns may in part be determined by statistical or numerical constraints. Differentiating the extent to which patterns in a given system are determined statistically, and where it requires explicit ecological processes, has been difficult. We tackled this challenge by directly comparing models from a constraint-based theory, the Maximum Entropy Theory of Ecology (METE) and models from a process-based theory, the size-structured neutral theory (SSNT). Models from both theories were capable of characterizing the …

Estimation Of Stray Dog And Cat Populations In Metropolitan Ankara, Turkey, Doğukan Özen, Dankmar Böhning, İsmayi̇l Safa Gürcan

Turkish Journal of Veterinary & Animal Sciences

Stray dogs and cats contribute to serious health problems in human societies around the world. Before any necessary interventions to control the stray dogs and cats, an accurate estimate of their populations should be attained. Yet, there is a very limited number of methods for an estimation. Some of them depend on the identification of marked or counted animals. However, problems arise when it is not possible to identify a previously captured animal. In this paper, we used a different approach to estimate the lower bound for the total number of dogs and cats in consecutively visited settlements that might …

Atopic Dog Skin Shows Decrease Of Claudin-1 But Increase Of Atopic Signature Cytokines, Sirin Theerawatanasirikul, Pakawadee Pongket, Lawan Larsuprom, Amornrate Sastravaha Jan 2016

Atopic Dog Skin Shows Decrease Of Claudin-1 But Increase Of Atopic Signature Cytokines, Sirin Theerawatanasirikul, Pakawadee Pongket, Lawan Larsuprom, Amornrate Sastravaha

Turkish Journal of Veterinary & Animal Sciences

Canine atopic dermatitis is a common allergic skin disease in dogs caused by defects in immunological and epidermal barriers. Claudin-1, a protein present in tight junctions, is associated with many skin conditions. Our aim was to investigate expression levels of claudin-1 and atopic signature cytokines in atopic and normal dog skins. The affected skin showed significantly decreased intensity and epidermal distribution of claudin-1 compared to the normal control skin (P < 0.05). The CD3+/CD4+ and CD3+/CD8+ T cell subsets, eosinophils, and neutrophils infiltrated the affected epidermis and dermis. The CD3+/CD4+ T cell subsets in lesional skin were significantly higher than CD3+/CD8+ T cell subsets. CLDN-1 mRNA expression was markedly downregulated in the lesional skin, while IL-17A was upregulated in both lesional and nonlesional skin. IL-4 and IL-31 mRNA was upregulated in the lesional skin, and TNF-α mRNA was significantly upregulated in the nonlesional skin (P < 0.01 and P < 0.05, respectively). Correlation-based hierarchical clustering showed that CLDN-1 expression was closely clustered with IL-31 but loosely clustered with L-4, IL-10, IL-13, and IL-17A. We suggest that the alteration of claudin-1 in atopic dogs may disrupt the skin barrier and allow an influx of allergens, inciting inflammatory cytokine responses.

Turkish Journal of Veterinary & Animal Sciences

This study aimed to investigate the mycoflora and chemotyping of Fusarium graminearum isolates in corn and barley used in industrial dairy farms in Khorasan-Razavi Province, northeastern Iran. For this purpose, a total of 128 corn and barley samples were collected from 16 different large industrial dairy farms. Mean moisture of the samples collected in different seasons of the year was significantly different (P < 0.05). The most prevalent fungi isolated from corn samples were Penicillium spp. (90.62%) and Aspergillus spp. (82.81%), and that of barley samples was Penicillium spp. (89.06%). Frequency of Fusarium spp. İn corn and barley samples was 85.93% and 26.56%, respectively. All isolates (100%) were confirmed as Fusarium using an ITS primer. Eight (11.11%) out of 72 Fusarium spp. İsolates were confirmed as F. Graminearum using species-specific primers. Five out of 8 F. Graminearum isolates were positive in terms of the presence of the trichothecene-producing gene using a Tri5-specific primer. Three and 2 out of 5 toxin-producing F. Graminearum isolates were positive using Tri13DON- and Tri13NIV-specific primers, respectively. In conclusion, the presence of toxigenic Fusarium in corn and barley samples used in feedstuffs in Iran is a potential risk to animal and human health.

Turkish Journal of Veterinary & Animal Sciences

Aluminosilicates are feed additives used for multiple purposes in the poultry industry. Bentonites, zeolites, and kaolins are types of aluminosilicate compounds that appear in the marketplace due to their capabilities as mycotoxin adsorbents and other qualifications. While there are some differences among their efficacies, anecdotal evidence confirms that these additives ameliorate aflatoxicosis and manure ammonia emission, and improve the durability of pelleted diets. Furthermore, these supplements are safe at 0.2%-1% inclusion levels in the commercial diet of broilers and layers and did not have any adverse effects on productive indices, and even promoted birds' performance. Nevertheless, their upper levels, especially …

Computational Tracking Of Shear-Mediated Platelet Interactions With Von Willebrand Factor, Adam Ralph, Martin Somers, Jonathan Cowman, Bruno Voisin, Emma Hogan, Hannah Dunne, Eimear Dunne, Barry Byrne, Nigel Kent, Antonio J. Ricco, Dermot Kenny, Simon Wong

Articles

The imaging of shear-mediated dynamic platelet behavior interacting with surface-immobilized von Willebrand factor (vWF) has tremendous potential in characterizing changes in platelet function for clinical diagnostics purposes. However, the imaging output, a series of images representing platelets adhering and rolling on the surface, poses unique, non-trivial challenges for software algorithms that reconstruct the positional trajectories of platelets. We report on an algorithm that tracks platelets using the output of such flow run experiments, taking into account common artifacts encountered by previously-published methods, and we derive seven key metrics of platelet dynamics that can be used to characterize platelet function. Extensive …
