Effective Neural Connectivity Deficits During Speech Auditory Feedback Processing In Post-Stroke Aphasia: An Fmri Study, Kimaya Sarmukadam, Vahid Nejati, Roozbeh Behroozmand

Faculty Publications

Post-stroke aphasia often results in significant impairments in speech production and auditory processing, necessitating a deeper understanding of the underlying neural connectivity within sensorimotor networks. In this study, we investigated neural connectivity within sensorimotor networks in individuals with post-stroke aphasia (n = 16) compared to neurotypical controls (n = 16). Functional magnetic resonance imaging (fMRI) data were acquired during speaking and listening tasks, accompanied by normal or randomly pitch-shifted (±100 cents) altered auditory feedback across trials. Dynamic causal modeling and parametric empirical bayes methods were used to analyze effective connectivity. The analysis revealed significant alterations in intrinsic and …

I Do, And I Will: Effectual Religiosity May Strengthen The Triad Chord Of Commitment For Women Of Faith, Tamara M. Chamberlain, Loren Marks, David C. Dollahite, Ashley Lebaron-Black, Elizabeth Kay Madsen, Christina N. Cooper

Faculty Publications

Although religiosity is commonly linked to marital satisfaction in sociological research, few studies have examined how it strengthens marital commitment among women of faith. This study explored the perspectives of religious, heterosexual married women using interviews in the United States from 196 highly religious couples with successful marriages. Three core themes emerged: (1) personal commitment—including the decision to marry, religious beliefs and practices, and the need for effort and sacrifice; (2) moral commitment—highlighting sexual relations before marriage, promises made before God, family, and friends, and views on fidelity and divorce; and (3) structural commitment— emphasizing the role of a religious …

Development Of Respiratory Sinus Arrhythmia In Young Infants With Autism Spectrum Disorder, Preterm Birth, And Typical Development, Jessica Bradshaw, John E. Richards, Julia Yurkovic-Harding, Eilis Mclaughlin

Faculty Publications

Respiratory sinus arrhythmia (RSA) is a key index of parasympathetic function and environmental adaptability. Lower resting RSA has been linked to preterm (PT) birth in infancy and autism spectrum disorder (ASD) in childhood, yet RSA across the first 2 years in young infants born PT or later diagnosed with ASD remains unknown. This study examined resting RSA and mean interbeat interval (IBI) development from 1 to 24 months in infants at varying ASD likelihoods, including infant siblings of children with ASD and those born PT. A longitudinal design tracked resting RSA and mean IBI in 137 infants from 1 to …

Robert Wesley McMullin (April 29, 1921 – January 3, 1995) was a Canadian composer, conductor, instrumentalist and music director. While he was born into a Mormon family in Utah, he was a proud Canadian: in a 1965 interview with Canadian Composer, he said: “The brain drain to the United States is a bad thing. It reduces our chances of arriving at a distinctive Canadian art form.” He composed works for orchestra, band, and piano, but the bulk of his compositions were for radio or television programming. Later in his career, he scored several films.

The Complexity Of Promoting Physical Activity In English State Primary Schools: An In-Depth Qualitative Analysis Of The Role Of Social Context, Robert Walker, Danielle House, Alice Porter, Ruth Salway, Simona Kent-Saisch, Michael Beets Ph.D., David Revalds Lubans, Frank De Vocht, Russell Jago

Faculty Publications

Background

Primary schools present an opportunity to equitably promote physical activity. To date, school-based interventions have had limited success. Contextual differences between schools could be a key factor that contributes to this lack of impact. However, the elements that constitute a school’s social context (i.e. the organisational, political, cultural, and sociodemographic characteristics) and how they might impact on primary school physical activity are unclear. The aims of this study were to conduct an in-depth qualitative analysis of state primary school social context related to physical activity and, using this analysis, provide recommendations for policy and practice.

We conducted one-to-one …

Decreasing Foraminiferal Flux In Response To Ongoing Climate Change In The Santa Barbara Basin, California, Emily Harvard, Katherine Cherry, Claudia R. Benitez-Nelson, Eric Tappa, Catherine V. Davis

Faculty Publications

The rapid response of foraminiferal assemblages to changing climate makes their shells an invaluable geological record of the past. However, the time frame over which foraminifera respond to climatic signals and the specific drivers influencing assemblage composition and abundance remain obscure. We focus on the impact of ongoing, anthropogenic climate change on planktic foraminifera in the California Current ecosystem, which would appear as a nearly instantaneous event in the sediment record. The Santa Barbara Basin sediment trap, located off the coast of California, USA since 1993, provides a record of more than 30 years of particulate and foraminiferal flux in …

Menopause-Related Changes In Sleep And The Associations With Cardiometabolic Health: A Narrative Review, Joshua R. Sparks, Xuewen Wang Ph.D., Faha

Faculty Publications

This narrative review examines the complex relationship between sleep changes during the menopausal transition and cardiometabolic risks. The most common complaint about sleep is increased awakenings during sleep. Other complaints include having trouble falling asleep, waking up too early, insufficient and non-restorative sleep, and overall poor quality. Sleep determined using objective methods also indicates that greater awakenings after sleep onset are associated with the period of menopausal transition. Polysomnography recordings suggest physiological hyperarousal during sleep. Changes in other sleep metrics, such as sleep latency and sleep duration, are less consistent, and some studies suggest they may not worsen during the …

Bovine Neutrophil Migration, Cd11a/Cd18 Expression, And Cytokine Response To Co-Culture With Mammary Gland Endothelial Cells And Epithelial Cells, David J. Mcclenahan

Faculty Publications

Movement of leukocytes from the circulatory system into a site of inflammation is a highly complex process. The migration of neutrophils into the lumen of the mammary gland during mastitis is no exception. There is information about the involvement of bacterial-produced products during this process, but less is known regarding the role of host products. Two bovine cell lines, a primary mammary gland endothelial cell line and an immortalized bovine mammary gland epithelial cell line (Mac-T), along with freshly isolated bovine neutrophils, were used to study this further. The cell lines were grown on inserts and in wells of tissue-culture …

Faculty Publications

Coronary Heart Disease (CHD) is the leading cause of death in the United States, affecting over 20.5 million adults. Previous studies link health behaviors – such as dietary behavior, physical activity, smoking, and alcohol consumption – to CHD risk. These studies typically use surveys and interviews, which, despite their benefits, are resource-intensive and limited by small sample sizes. Using large-scale national level anonymized smartphone-based location data, our study examines whether health behaviors that are proxy measured by place visitation are associated with CHD prevalence across US census tracts. This study utilized data from multiple sources, including demographic and socioeconomic characteristics, …

Growth Of Cylindrical Micelles And Their Use To Prepare Porous Materials With Tailored Dimensions And Alignment, Mengxue Zhang, Xiaomeng Li, Chuanbing Tang, Morgan Stefik

Faculty Publications

Materials with cylindrical pores are optimal for electrochemical devices and filtration due to their straight paths with minimal tortuosity when aligned. Polymer templates have led to many individual cylindrical architectures however the independent tailoring of pore and wall dimensions has remained elusive. Here short cylindrical micelle templates (PEO-b-PS) with glassy cores enabled the fabrication of sample series with constant cylindrical pore diameter (∼63 nm) and tailored wall thickness (TiO₂, ∼45–100 nm). This ShortCyl series (aspect ratio 4.25) had modest alignment that was attributed to the low free-energy cost for misalignment. Though the plasticized micelles (DCM present) …
