No Evidence That Footedness In Pheasants Influences Cognitive Performance In Tasks Assessing Colour Discrimination And Spatial Ability, Mark A. Whiteside, Mackenzie M. Bess, Elisa Frasnelli, Christine E. Beardsworth, Ellis J.G. Langley, Horik Jo Van, Joah R. Madden

School of Biological and Marine Sciences

ABSTRACTThe differential specialization of each side of the brain facilitates the parallel processing of information and has been documented in a wide range of animals. Animals that are more lateralized as indicated by consistent preferential limb use are commonly reported to exhibit superior cognitive ability as well as other behavioural advantages. We assayed the lateralization of 135 young pheasants (Phasianus colchicus), indicated by their footedness in a spontaneous stepping task, and related this measure to individual performance in either 3 assays of visual or spatial learning and memory. We found no evidence that pronounced footedness enhances cognitive ability in any …

A Study Of Nones In Brazil And The Usa In Light Of Secularization Theory With Missiological Implications, Jolive R. Chavez

Dissertations

The growth of those who declare themselves to be Nones, or religiously unaffiliated, in Brazil and the USA has been continuously higher than that of the general population. In Brazil, they are the third-largest group in the religious field, behind only Catholics, and Pentecostal evangelicals. In the USA, they are the second largest group, after Protestants as a whole. The Nones, in their diverse groups, are more represented among the youth in both cultures, and reflect the modern and postmodern influences of contemporary secularism, being a product of the process of changing human thought.

This work studies the Nones, in …

Burden Of Rare Deleterious Variants In Wnt Signaling Genes Among 511 Myelomeningocele Patients, Luke Hebert, Paul Hillman, Craig Baker, Michael Brown, Allison Ashley-Koch, James E Hixson, Alanna C Morrison, Hope Northrup, Kit Sing Au

Faculty, Staff and Student Publications

Genes in the noncanonical WNT signaling pathway controlling planar cell polarity have been linked to the neural tube defect myelomeningocele. We hypothesized that some genes in the WNT signaling network have a higher mutational burden in myelomeningocele subjects than in reference subjects in gnomAD. Exome sequencing data from 511 myelomeningocele subjects was obtained in-house and data from 29,940 ethnically matched subjects was provided by version 2 of the publicly available Genome Aggregation Database. To compare mutational burden, we collapsed rare deleterious variants across each of 523 human WNT signaling genes in case and reference populations. Ten WNT signaling genes were …

Prevalence And Predictors Of Chronic Pain Intensity And Disability Among Adults With Sickle Cell Disease, Nadine Matthie, Coretta Jenerette, Ashley Gibson, Sudeshna Paul, Melinda Higgins, Lakshmanan Krishnamurti

Faculty, Staff and Student Publications

Among 170 adults with sickle cell disease, we evaluated chronic pain impact and disability prevalence, assessed age and gender differences, and identified psychosocial predictors of chronic pain intensity and disability. Most participants had a high level of disability. Chronic pain intensity and disability were significantly associated with pain catastrophizing and chronic pain self-efficacy, and worsened with age. Further research is needed to confirm study findings and develop interventions, including palliative care approaches that address catastrophizing and disability, particularly for young women and middle-aged adults with sickle cell disease. Moreover, consistent clinical assessment of chronic pain and psychosocial health should be …

Adenosine At The Interphase Of Hypoxia And Inflammation In Lung Injury, Xiangyun Li, Nathanial K Berg, Tingting Mills, Kaiying Zhang, Holger K Eltzschig, Xiaoyi Yuan

Faculty, Staff and Student Publications

Hypoxia and inflammation often coincide in pathogenic conditions such as acute respiratory distress syndrome (ARDS) and chronic lung diseases, which are significant contributors to morbidity and mortality for the general population. For example, the recent global outbreak of Coronavirus disease 2019 (COVID-19) has placed viral infection-induced ARDS under the spotlight. Moreover, chronic lung disease ranks the third leading cause of death in the United States. Hypoxia signaling plays a diverse role in both acute and chronic lung inflammation, which could partially be explained by the divergent function of downstream target pathways such as adenosine signaling. Particularly, hypoxia signaling activates adenosine …

Transcriptional Insights Into Pathogenesis Of Cutaneous Systemic Sclerosis Using Pathway Driven Meta-Analysis Assisted By Machine Learning Methods, Xiao Xu, Meera Ramanujam, Sudha Visvanathan, Shervin Assassi, Zheng Liu, Li Li

Faculty, Staff and Student Publications

Pathophysiology of systemic sclerosis (SSc, Scleroderma), an autoimmune rheumatic disease, comprises of mechanisms that drive vasculopathy, inflammation and fibrosis. Understanding of the disease and associated clinical heterogeneity has advanced considerably in the past decade, highlighting the necessity of more specific targeted therapy. While many of the recent trials in SSc failed to meet the primary end points that predominantly relied on changes in modified Rodnan skin scores (MRSS), sub-group analysis, especially those focused on the basal skin transcriptomic data have provided insights into patient subsets that respond to therapies. These findings suggest that deeper understanding of the molecular changes in …

Assessing The Impacts Of Metals And Radionuclides On Marine Mussels: Proteomics And Ecotoxicological Approaches, Charlotte Crowther

School of Biological and Marine Sciences Theses

It is well established that anthropogenic contaminants occur in all probable combinations and therefore are not isolated in their threat to the aquatic environment. Recently there has been an increasing interest in measuring pollutants in environmentally realistic conditions to predict the potential detrimental outcomes on the ecosystem. This includes realistic levels of contamination concentrations, chronic exposures duration and mixtures of contaminants. With this perspective, in the present work, marine mussels, Mytilus galloprovincialis were exposed to concentrations of copper (5, 32 μg L-1), lead (5, 25 μg L-1) and tritiated water (HTO, 1.5, 5 MBq L-1) both individually and as a …

Role Of Aspect In Terrestrial And Intertidal Distributional Patterns, And Ecological Processes, Axelle Amstutz

School of Biological and Marine Sciences Theses

Understanding better the impact of climate and changing environmental conditions on species and ecosystems has become one of the pressing research priorities. In addition, a need for more realistic field-based climate change experiments and focus on community and ecosystem functioning has grown in the last decade. The main aim of this PhD work was to study the effect of mainly temperature variation on species and ecosystems, by studying small-scale aspect (slope orientation) on both intertidal gullies and hedgerows/road verges in SW England. Such paralleled studies between terrestrial and marine ecosystem are sparse. I especially investigated (1) abiotic variations, (2) species …

Coastal Embayment Rotation; Morphological Response To Bi-Directional Wave Climates And Atmospheric Forcing, Mark Wiggins

School of Biological and Marine Sciences Theses

Beach rotation through longshore sediment transport can alter shoreline orientation, increasing erosional risks for coastal communities at short-term (storm events) and decadal to centurial time scales (long-term evolution). Identifying, predicting and planning for embayed beach rotation requires understanding of the morphological response to changes in directional wave climates driven by atmospheric forcing. Through assessment of annual to centurial datasets, this thesis aims to improve understanding of beach rotation at local (embayment) to regional (coastline) extents. The multi-annual rotational response of a 12-km, longshore-dominated gravel embayment (Start Bay, Devon, UK) to a set of extreme and contrasting bi-directional winter wave conditions …

The Effects Of Thermal Acclimation On Hypoxia Thresholds: An Integrative Approach, Michael Hinton Collins

School of Biological and Marine Sciences Theses

Marine animals are increasingly threatened by a combination of reduced environmental oxygen (hypoxia) and chronically rising sea temperatures. Our current understanding of the effects of temperature on hypoxic performance is based predominantly upon studies of acute warming demonstrating reductions in hypoxic performance in numerous species. However, these studies do not take account of the possibility for altered performance via thermal acclimation. They are also largely focused at the organismal level with integration of different levels of biological organisation just beginning to appear. This thesis takes an integrative approach to investigate the effects of thermal acclimation on hypoxia thresholds using gammarid …

Initial Education Of Philosophy Teachers In Colombia: Association Between New Public Policy Requirements And National Standardized Tests, Alejandro Farieta-Barrera

Australian Journal of Teacher Education

This paper evaluates the association between new public policy requirements for B.Ed. programs in Colombia —1) demand high-quality accreditation, 2) restrict distance modality, 3) restrict multidisciplinary programs, and 4) increase academic credits in education courses and pedagogical practices— and the outcomes of 1387 B.Ed. in Philosophy students in the National Saber Pro test 2016-2018, in ‘Education’ component. The methodology was multilevel linear regression; the residential region is the level variable, and were included other control variables (gender, age, ethnic minority, socioeconomic index, etc.). The results show that outcomes are associated with pedagogical practices and with non-multidisciplinary programs, supporting new regulations. …

Examining Teacher Agency Among Teacher Educators: An Action Research In Vietnam, Tung Ngoc Vu

Teacher agency is an important topic in educational research, but its theoretical observations have not filtered down into practical Vietnamese teaching contexts. The action research project described here showcases a training-based intervention for teacher educators in various disciplines at eight universities in Vietnam. The intervention aimed to develop teaching skills and increase knowledge for teacher educators by helping them explore their students’ learning needs and facilitate their professional development. This study occurred within the context of changing Vietnamese political, cultural, economic, and social ways of being. Eight Vietnamese teacher educators of different cultural backgrounds, and working across a variety of …

Entangling Our Thinking And Practice: A Model For Collaboration In Teacher Education, Peta White, Jo Raphael, Shelley Hannigan, John Cripps Clark

Australian Journal of Teacher Education

Collaboration is a key component of our practice as teachers and teacher educators and there is a need to develop generative models for collaboration among teacher educators. We have created and tested a model of collaboration. Data were drawn from: recordings of monthly group meetings; discussion threads and documents on our leaning management site; individual interviews with all members of the group conducted three times across the project; and reflections on these interview transcripts by individual annotation and group discussions. The model includes a collaborative overarching research project and, nested under this mantle, a series of focused research projects conducted …

Pre-Service Science And Mathematics Teachers’ Teaching Efficacy Beliefs And Attitudes Toward Teaching: A Partial Correlation Research, Büşra Kartal

Australian Journal of Teacher Education

Teachers with a high level of self-efficacy and positive attitudes are more likely to use new and constructivist approaches and to create a learning environment in which students may develop 21st-century skills. Examining pre-service teachers’ attitudes and beliefs related to teaching allow teacher preparation programs to evaluate their effectiveness on beliefs and attitudes. This correlational research investigated pre-service elementary science and mathematics teachers’ beliefs and attitudes due to gender, grade level, and department, and revealed the reliable correlation between beliefs and attitudes performing partial correlation. Results show that females feel more efficacious in teaching and have more positive attitudes than …

Primary Science Teachers’ Self-Efficacy And Outcome Expectancy: A Case Study, Gillian Ward, Helen Dixon, Helen Withy

Australian Journal of Teacher Education

Self-efficacious teachers are critical in the development of students’ positive attitudes towards science and scientific literacy yet to date little attention has been given to studies of experienced teachers of primary science and development of their self-efficacy (SE) beliefs. The aim of this study was to explore how two experienced teachers of primary science built their SE beliefs and outcome expectancy. Bandura’s (1977) SE framework provided the conceptual lens to understand participants’ experiences and beliefs. Findings suggest that teachers’ SE beliefs had developed over time, creating a foundation for a strong expectancy outcome. Each of the sources of influence made …

Local Wisdom In Regenerative Teacher Practices, Sue E. Smith, Jon C. Mason, Majella Bowden

Australian Journal of Teacher Education

In this article, teacher professional practice is conceptualised within a regenerative framing as a synthesis of intercultural perspectives drawn from wisdom traditions, placing ethics-in-action alongside reflection-in-action. Regenerative practice foregrounds the need for renewal connecting professional learning with lifelong learning. Global sustainability agendas also inform this endeavour, reminding us of our connectedness within living ecosystems while ‘local wisdom’ is considered a primary source to inspire regeneration. Ecological models of education are therefore explored to determine the nature and scope of regenerative practices. Isolation imposed by the global pandemic provided opportunity to reflect upon our own practices and how these inter-relational constructs, …

Prevalence, Predictors And Sources Of Information Regarding Neuromyths In An Australian Cohort Of Preservice Teachers, Mark Carter, Penny Van Bergen, Jennifer Stephenson, Carol Newall, Naomi Sweller

Australian Journal of Teacher Education

The term neuromyths refers to misconceptions about learning and the brain. Educator neuromyths may result in inappropriate instruction, labelling of learners, and wasted resources. To date, little research has considered the sources of these beliefs. We surveyed 1359 Australian preservice educators (M = 22.7, SD = 5.7 years) about their sources of information for 15 neuromyth and 17 general brain knowledge statements. Consistent with previous studies, neuromyth beliefs were prevalent. Predictors of neuromyth accuracy included general brain knowledge and completion of university classes addressing neuromyths, although effects were modest. Depending on the belief, participants relied on general knowledge, academic staff, …

Evidence-Based Reasoning Processes In Education: A Model To Support Interventionist Practice., Natasha Ziebell, Jemma Skeat

Australian Journal of Teacher Education

The Evidence-based Reasoning model is a systematic inquiry into student learning to determine what interventions are required in classroom contexts. The four step process includes noticing students who need additional support in their learning, the use of assessment data to establish an evidence-base, and subsequent interpretation that leads to decision making. The reasoning process is supported by collaborative practice models both within and beyond the teaching profession. The evaluation of interventions is integral in determining the impact that interventions have on student learning.

Dual Enrollment Students Placing Perspective On The Act Mathematics Benchmark, Monica Newman

Murray State Theses and Dissertations

For high school students achieving high ACT/SAT scores is crucial for admittance, scholarships, and coursework requirements. Dual enrollment students still have to meet the admittance and coursework requirements to be enrolled in a dual enrollment course even though the class could be scheduled for more time than the traditional course taught on campus. The purpose of this study was to determine if ACT predictors closely align to student success for dual enrollment students who complete a college algebra course in a high school setting with an adjunct professor who is a full-time high school teacher. Archival data from 188 dual …

One Door Opening Is Another Person's Insult: Examining Benevolently Sexist Behaviors And Attitudes In American Males, Rachael Turner

Murray State Theses and Dissertations

This study explores Ambivalent Sexism Theory and takes a closer look at the correlation between the behaviors and attitudes that surround it. In this study 133 male participants completed surveys questioning their acceptance and engagement in certain benevolent behaviors, as well as measuring their level of being considered sexist and kind. Results indicate that men who endorsed benevolently sexist ideology more frequently engaged in benevolent behaviors with women as well as believed this behavior was appropriate. However, regression analysis show kindness had a higher predictability in determining whether the men would in engage in these behaviors and consider it appropriate.

Population Demographics Of Silver Carp Hypophthalmichthys Molitrix In Kentucky Lake, Allison M. Lebeda

Murray State Theses and Dissertations

Invasive species continue to threaten aquatic ecosystems in the United States. Silver Carp Hypophthalmichthys molitrix have successfully infiltrated much of the Mississippi River Basin, including Kentucky Lake – a large reservoir located on the Tennessee River in Western Kentucky. Although Silver Carp have been present in Kentucky Lake for at least a decade, until recently, very little was known about the population, how often successful reproduction is occurring, or the environmental conditions that facilitate strong year-classes. Hence, it is difficult for managers to predict the potential impact of Silver Carp on native species. Silver Carp were collected from Kentucky Lake …

The Impact Of Credible And Non-Credible Treatment Information On Depression Treatment Preferences In College Students, Sydney Hayden, Dr. Michael Bordieri, Phd

Murray State Theses and Dissertations

Previous research has demonstrated the importance of considering client treatment preference when providing treatment for depression. However, little research has focused on the impact of treatment information on client preference. This study investigated differences in treatment preference between potential clients that read credible treatment information and those that read non-credible treatment information. The study was conducted via an online survey that was administered to undergraduate students. Eighty participants were randomly assigned to either read credible treatment information or non-credible treatment information and treatment preferences was assessed via a free response item before and after information regarding treatments was given. Overall, …

Cannabidiol In The Horse: Pharmacokinetics And Effects Of A Pelleted Supplement On Reactivity And Movement, Anna L. Draeger

Murray State Theses and Dissertations

A multitude of claims exist regarding therapeutic benefits of cannabidiol (CBD) in human and animal medicine. Though supportive evidence of CBD as a nutraceutical option exists, lack of regulation means that product safety, consistency, and efficacy cannot be guaranteed. Trials for specific conditions and species are needed. The objective of this study was to evaluate CBD safety and use effects on reactivity and movement in the horse. Project 1 examined the bioavailability of a single 50 mg dose of an oil and pelleted CBD product. One of 2 Quarter Horse geldings received the oil product. The second received the pelleted …

Effect Of Organic Soil Amendment On Hemp, Mounica Talasila

Murray State Theses and Dissertations

The research study is about the impact of different levels of organic soil amendment on the levels of psychoactive compounds produced in industrial hemp. Inorganic or chemical pesticides or fertilizers are not as extensively used in hemp as in other crops. Apart from this, using an organic soil amendment would be an environmentally sustainable way. A randomized block design (RBD) model was used to study the impacts of the soil amendment. The soil amendment used is called “Rehab” a product of Organilock created from the remnants of animals like fish and chicken. This research design has 3 different soil amendment …
