Emerging Aiot-Based Approaches For Early Detection Of Cardiac Diseases: A Review, Balqees Talal Hasan, Zaid J. Al-Araji, Zainab Al-Badrany, Sarah Kanaan Hamzah, Abdulmajeed Sulaiman

Mesopotamian Journal of Artificial Intelligence in Healthcare

Cardiovascular disease continues to pose a serious global health burden, emphasizing the need for smart, ongoing, and clinically trustworthy systems for early detection of this condition. The convergence of IoT-enabled sensing technologies with AI has led to the rise of an innovative paradigm known as AIoT, integrating technologies such as machine learning, deep learning, edge and fog computing, and cloud-based analytics with the aim of real-time cardiac monitoring and diagnostic decision support. Despite rapid expansion, current literature appears disparate in its coverage of sensing modalities, learning algorithms, system architectures, data sets, evaluation criteria, and clinical applications. To remedy this, a …


We Don't See Race, We See Blue: A Case Study Of Police Unions As Racialized Organizations, Sarahfina Aubrey Peterson Aug 2026

We Don't See Race, We See Blue: A Case Study Of Police Unions As Racialized Organizations, Sarahfina Aubrey Peterson

Dissertations and Theses

In the late 1960s, police began to unionize. Today, they are the most well-organized labor force in the United States, with 70% to 80% of sworn officers now represented by a union. Though it has been decades, little scholarship has developed about how police unions affect policing. Much of the research that does exist uses race-neutral frames to address an organization steeped in racial history. This study aims to address this gap in scholarship, in part, by introducing race as a motivation for and explanation of organizational output.

This research applies Victor Ray's racialized organizations theory to police unions. I …


Mindful Parenting And Toddlers' Food Responsiveness: The Role Of Controlling Feeding Practices, Qingyu Jiang, Holly Wilhite, Natalie A. Williams, Dipti A. Dev, Caron A. C. Clark, Pearl Avari, Sarah B. Ladd Aug 2026

Mindful Parenting And Toddlers' Food Responsiveness: The Role Of Controlling Feeding Practices, Qingyu Jiang, Holly Wilhite, Natalie A. Williams, Dipti A. Dev, Caron A. C. Clark, Pearl Avari, Sarah B. Ladd

Journal of Extension

Controlling feeding practices may negatively impact children's eating behaviors. Mindful parenting may offer a promising way to reduce the use of these practices. This study examined the mediating role of pressuring children to eat and using food as a reward in the association between mindful parenting and toddlers' food responsiveness. Results indicated that higher levels of mindful parenting were associated with lower pressuring to eat, which was related to lower food responsiveness in toddlers. The results may inform Extension professionals providing mindfulness strategies for mothers of young children to improve feeding practices, ultimately reducing children's unhealthful eating behaviors.

Department of Neurology Faculty Papers

OBJECTIVES: Multiple sclerosis (MS) is a complex, progressive neurodegenerative autoimmune disease and a major cause of neurological disability worldwide. MS affects approximately 2.8-3 million people, predominantly presenting as relapsing-remitting MS (RRMS) that frequently converts to secondary progressive disease, while effective options for progressive phenotypes remain limited.

METHODS: This review reframes MS immunotherapy through a tolerance-centric paradigm, distinguishing continuous maintenance disease-modifying therapies (DMTs) from immune reconstitution therapies (IRTs) and emerging antigen-specific tolerance strategies.

RESULTS: Classical immune reconstitution therapies, including alemtuzumab, cladribine, and autologous hematopoietic stem cell transplantation (aHSCT), have demonstrated durable disease control and prolonged periods of no evidence of disease …


Exploring Elite Athletes’ Perceptions Of The Practice Of Mindfulness For Mental Health And Optimal Performance, Omar A. Sesay Aug 2026

Exploring Elite Athletes’ Perceptions Of The Practice Of Mindfulness For Mental Health And Optimal Performance, Omar A. Sesay

Walden Dissertations and Doctoral Studies

Elite athletes experience physical, cognitive, and emotional demands that affect athletic performance and personal well-being, increasing the risk for anxiety, depression, burnout, attentional difficulties, and maladaptive coping strategies. Mindfulness-based stress reduction (MBSR) has been examined for its effect on attentional control, emotional regulation, cognitive flexibility, and stress resilience, but limited qualitative research has examined how elite athletes experience the practice of mindfulness. The purpose of this generic qualitative study was to explore elite athletes’ perceptions of the practice of mindfulness for mental health and optimal performance. The theoretical framework draws from mindfulness theory and MBSR principles. Semistructured interviews were conducted …


Postscript To Gatherings, Volume 3, Farha Ternikar, Heather Mooney Aug 2026

Postscript To Gatherings, Volume 3, Farha Ternikar, Heather Mooney

Gatherings

We write this postscript as we are approaching the 25th anniversary of 9/11. We don’t take this lightly as feminists or sociologists.  The War on Terror has shaped both Islamophobia and anti-Arab discrimination for decades. And after October 7, 2023, we were again devastated to see escalating tragedies in the Middle East. Farha Ternikar and Heather Mooney, as co-editors of this volume, went into this endeavor with heavy hearts.


Roots That Refuse To Die: Narratives Of Displacement And Solidarity In Palestinian And Chicanx Feminist Traditions, R. H., Lea Colchado-Joaquín Aug 2026

Roots That Refuse To Die: Narratives Of Displacement And Solidarity In Palestinian And Chicanx Feminist Traditions, R. H., Lea Colchado-Joaquín

Gatherings

Amidst the recent passing of Senate Bill 17 and increasing restrictions on academic freedom, and efforts to shut down encampments, political tensions have been on the rise at Texas university campuses. As women of color scholars learning to navigate these challenges, we are committed to fostering safe pedagogical spaces that honor minoritized students’ voices. This paper examines interpretations of solidarity narratives between Chicanx and Palestinian feminist authors through a decolonial feminist lens and employs an autoethnographic methodological approach such as autohistoria-teoría to highlight parallels between the authors' lived realities. Authors begin this conversation by using their own narratives of resistance …


Kinship As Ethical Caring In Genocidal Times, Khawla Badwan, Sunny Singh Prof Aug 2026

Kinship As Ethical Caring In Genocidal Times, Khawla Badwan, Sunny Singh Prof

Gatherings

As the world bears witness to the first live-streamed genocide1 in history with full collaboration of the so-called free world, whatever ethics had been defined and legally encoded by imperial powers in the aftermath of the Second World War are no longer functioning or indeed relevant. Instead at individual and collective levels, we must develop a more relational and nested approach to ethical caring; one that moves beyond saviourism and distant witnessing. To demonstrate this relationality, we present our thinking through a dialogic genre of creative and critical reflections and interventions. This dialogue draws and builds on entanglements of …

Action Steps Toward Equity In Communication Sciences And Disorders: A Program Evaluation Of Student Self-Efficacy, Monica Bellon-Harn, Lekeitha Morris, Mark Trahan

Teaching and Learning in Communication Sciences & Disorders

Abstract

Purpose: Within communication sciences and disorders (CSD), preparing students for equitable practice requires instruction aligned with social justice principles. Because students’ confidence in engaging in these practices may influence future behavior, this study examined the effects of an asynchronous program, Action Steps toward Equity (ASE-CSD) on undergraduate and graduate CSD students’ self-efficacy for practices aligned with social justice principles.

Method: A pretest-posttest quasi-experimental design was used with undergraduate (n = 16) and graduate (n = 33) CSD students who completed ASE-CSD. Participants completed the Social Justice Scale (SJS; Torres-Harding et al., 2012), which assessed self-efficacy associated with …

Simulated Participant Engagement In Communication Sciences & Disorders Programs: A Scoping Review, Jason Konzelmann, Richard I. Zraick Aug 2026

Simulated Participant Engagement In Communication Sciences & Disorders Programs: A Scoping Review, Jason Konzelmann, Richard I. Zraick

Teaching and Learning in Communication Sciences & Disorders

Introduction. Simulated participants (SPs) are widely used in medical and nursing education, but their application in allied health, including Communication Sciences and Disorders (CSD), remains limited. Despite accreditation standards supporting simulation in CSD training, student engagement with SPs is still uncommon.

Objectives. This scoping review examined recent literature on SP use in CSD programs involving speech-language pathology or audiology students or providers. We explored how SPs were integrated and identified gaps for future research.

Methods. Guided by PRISMA-ScR, we searched six databases and an internet search yielded one additional article. Studies published between 2019 and 2025 were included if they …

Prologue To Special Section, David Ainley

Marine Ornithology

In 1972, the Pacific Seabird Group, “dedicated to the study and conservation of Pacific seabirds and their environment,” was founded by a group of idealistic US and Canadian Early Career Scientists (led by George Divoky, and egged-on by some older mentors) (Fig. 1). It was a heady time, with publication of Rachael Carson's Silent Spring, the first Earth Day, and the enactments of the Endangered Species Act, National Environmental Policy Act, and Clean Water Act. During this time, besides DDT and its effects on marine birds, major marine oil spills occurred in waters off Santa Barabara and San Francisco. …

Conserving Seabirds: Actions Of The Pacific Seabird Group During Its First 40 Years., Craig S. Harrison

Marine Ornithology

The Pacific Seabird Group (PSG), founded in 1972, is “dedicated to the study and conservation of Pacific seabirds and their environment.” During its first 40 years, PSG undertook scores of conservation actions, although as an all-volunteer organization, PSG lacked the capacity to implement many programs or projects. It achieved its conservation goals through leadership, raising issues, bringing the best science to decision makers, and serving as a catalyst for others to act. PSG has been especially influential in six areas: (1) eradicating invasive alien animals from seabird colonies; (2) conserving Marbled Murrelets Brachyramphus marmoratus; (3) protecting seabird colonies in …

Behavioral Insights Into The Galapagos Penguin Spheniscus Mendiculus: A Day In His Life—An Ethological Portrait., Jonathan Cueva, Wilson Iñiguez, Gregory Marshall, Christian Sevilla, Andrea Coloma, Lorena Venegas, Gustavo Jiménez-Uzcátegui

Marine Ornithology

The Galapagos Penguin Spheniscus mendiculus, endemic to the Galápagos Archipelago, faces increasing ecological pressures threatening its population. This study aimed to characterize its daily behavioral patterns to better understand its adaptations and vulnerability to ecosystem changes. In one breeding locality, the Marielas Islets, we mounted a Crittercam on a male penguin to assess interactions with its mate and its behavior over a 24-hr period. Behaviors were classified as Diving, Foraging, Grooming, Intraspecific Interaction, Interspecific Interaction, Loafing, Prospecting, Resting, Surface Dipping, and Swimming. We analyzed behavioral data using chi-square tests and transition heat-maps. Results revealed predominantly surface behaviors—Prospecting (41.2% of …

Breeding Parameters Of The Gull-Billed Tern Gelochelidon Nilotica In Boughrara Lagoon, Southeast Tunisia., Amel Neb, Slaheddine Selmi

Marine Ornithology

We provide, for the first time, data on the breeding parameters of the Gull-billed Tern Gelochelidon nilotica in Tunisia, at Boughrara Lagoon. From May to July 2024, we monitored a breeding colony located on a small islet in the northern part of the lagoon. In total, 112 nests were monitored: 71 nests initiated in mid-May (early clutches) and 41 in early June (late nests). Clutch size ranged from one to four eggs (mean ± standard deviation [SD] = 2.51 ± 0.06), with no significant difference between early and late nesters. Egg volume ranged from 14.65 to 49.23 cm3 (mean ± …


Sex And Age Characteristics Of Northern Fulmars Fulmarus Glacialis Used In Programs To Monitor Plastic Ingestion., Jan A. Van Franeker, Susanne Kühn Aug 2026

Sex And Age Characteristics Of Northern Fulmars Fulmarus Glacialis Used In Programs To Monitor Plastic Ingestion., Jan A. Van Franeker, Susanne Kühn

Marine Ornithology

Carcasses of beached or accidentally killed Northern Fulmars Fulmarus glacialis, collected for monitoring plastic ingestion, have shown that the incidence of litter may vary over time and by region. Age, sex, and season of fulmar collection appear to affect the quantity of plastics ingested. More detailed analyses of monitoring data thus require reliable and consistent methods for assessing age and sex. Methods were first described in a monitoring manual in 2004 and later in international guidelines, but age and sex definition required further clarification. A large dataset of 3,790 dissected birds now allows for detailed descriptions of sex and …


Seabirds As Ecosystem Engineers: Providing Arthropod Habitat On Oceanic Islands., Kanon Mizukoshi, Kazuto Kawakami, Takashi Kamijo Aug 2026

Seabirds As Ecosystem Engineers: Providing Arthropod Habitat On Oceanic Islands., Kanon Mizukoshi, Kazuto Kawakami, Takashi Kamijo

Marine Ornithology

Seabirds play several important ecological roles on oceanic islands through their high-density breeding. Their ecosystem functions—such as nutrient cycling through excretion or terrestrial vegetation disturbance through trampling—are well known; however, little is known of their roles as ecosystem engineers. Nests and burrows can be densely concentrated in seabird colonies, by which seabirds can affect adjacent terrestrial ecosystems, especially affecting arthropods that use these structures as food or habitats. However, studies investigating the species composition of arthropods that inhabit seabird nests are limited. To characterize the arthropod faunas in seabird nests, this study surveyed and analyzed 90 nests of three seabird …


Comparing Counts Made From Drone-Based And Boat-Based Photography For Surveying Thick-Billed Murre Uria Lomvia Cliff Colonies., Ewan Macdonnell, Sarah E. Gutowsky, Kyle H. Elliott Aug 2026

Comparing Counts Made From Drone-Based And Boat-Based Photography For Surveying Thick-Billed Murre Uria Lomvia Cliff Colonies., Ewan Macdonnell, Sarah E. Gutowsky, Kyle H. Elliott

Marine Ornithology

Surveys of cliff-nesting seabirds from sea level or ground level often miss individuals hidden by topography, leading to underestimates of abundance. Thick-billed Murres Uria lomvia are especially challenging to survey accurately due to their dense nesting on vertical cliff ledges in remote northern regions. In Canada, updated colony surveys are needed, as currently used population estimates, done from boats, are outdated. Drones offer better vantage points and may reduce availability bias (i.e., the proportion of birds present but not visible), but direct comparisons with boat-based counts are essential. We compared murre counts from drone- and boat-based photographs of six vertical …


Foraging Areas Of Breeding Adult Sooty Terns Onychoprion Fuscatus On Bird Island, Seychelles., Jessica L. Neumann, Ruth E. Dunn, Malcolm A. C. Nicoll, Christine S. Larose, Chris Foster, Gary Brodin, Chris J. Feare Aug 2026

Foraging Areas Of Breeding Adult Sooty Terns Onychoprion Fuscatus On Bird Island, Seychelles., Jessica L. Neumann, Ruth E. Dunn, Malcolm A. C. Nicoll, Christine S. Larose, Chris Foster, Gary Brodin, Chris J. Feare

Marine Ornithology

The foraging areas used by adult Sooty Terns Onychoprion fuscatus during incubation and early chick-rearing on Bird Island, Seychelles, were investigated using small GPS loggers. Birds departed the colony mainly during the night and foraged by day. Most foraging trips were completed within 24 hr, but during incubation the longest duration recorded was seven days and 14 hr (during which the bird travelled 2,783 km and reached a maximum of 692 km from the colony). Departures were generally in an arc from south (180°) through westerly to 40°. Sooty Terns foraged frequently in waters over the Seychelles Bank shelf break, …

First Gps Tracking Of The Black Storm Petrel Hydrobates Melania., Jorge Cristerna, Gemma Abaunza, Joel Aarón López-Hernández, Cecilia Soldatini, Yuri Vladimir Albores-Barajas, Federico De Pascalis, Jacopo G. Cecere

Marine Ornithology

The research reported here, conducted at Archipiélago de Espíritu Santo National Park, Baja California Sur, Mexico, establishes the first successful application of biologging on a Black Storm Petrel Hydrobates melania. Results yielded preliminary insights into this population's marine movements during nesting. The device used, weighing less than 3% of the bird's body mass, recorded a 181-km foraging trip. Subsequent trajectory analysis indicated navigation behavior that potentially was optimized to use crosswind assistance. The individual showed no weight loss post-retrieval, a finding that suggests this method is viable and unharmful, demonstrating the feasibility of using miniaturized tracking devices to unravel …

Predicting Suitable Marine Habitat For Pink-Footed Shearwaters Ardenna Creatopus In The Waters Along The Pacific Coast Of Canada., Sonya A. Pastran, Patrick D. O’Hara, Kenneth H. Morgan, Caroline H. Fox, W. Eric Gross

Marine Ornithology

Anthropogenic activities are threatening global marine ecosystems, with seabirds representing a vulnerable group that has experienced pronounced population declines in recent decades. The ability to identify important marine areas for vulnerable seabirds is fundamental to conservation initiatives. The Pink-footed Shearwater Ardenna creatopus (listed as Endangered in Canada) breeds only in Chile, but during the non-breeding season, it ranges northward to waters off Canada's Pacific coast and the northern Gulf of Alaska. Using at-sea survey data spanning from 1992 to 2019, we examined the relationship between the species' distribution and environmental variables using a two-step generalized additive model approach. Cross-validation with …


Tasmanian Records Of Vagrant Penguins, 1991–2025., Eric J. Woehler Aug 2026

Tasmanian Records Of Vagrant Penguins, 1991–2025., Eric J. Woehler

Marine Ornithology

During the period 01 January 1991 to 31 August 2025, there were 274 records of vagrant penguins in Tasmania. These records represented three genera: Aptenodytes, Pygoscelis, and Eudyptes. The most frequently reported species were Fiordland Penguin E. pachyrhynchus, Royal Penguin E. schlegeli, and King Penguin A. patagonicus. High numbers of records were reported from 10 years, with a peak in 1999 and a lower peak in 2023. Records from January to March accounted for approximately 42% of all vagrant penguin occurrences and corresponded with the arrival of pre-moult birds of all ages. A range …


Comparative Diet Analysis Of Three Larid Species Nesting At Isla Rasa, Gulf Of California, Mexico., Enriqueta Velarde, Lloyd T. Findley Aug 2026

Comparative Diet Analysis Of Three Larid Species Nesting At Isla Rasa, Gulf Of California, Mexico., Enriqueta Velarde, Lloyd T. Findley

Marine Ornithology

Isla Rasa, situated in highly productive waters of the Gulf of California, has the largest nesting colony of Royal Terns Thalasseus maximus (as many as 17,000 individuals) in the Mexican Pacific, sharing this site with 300,000 Elegant Terns T. elegans and 260,000 Heermann's Gulls Larus heermanni. During eight breeding seasons between 1996 and 2011, we found that the Royal Tern diet contained over twice the number of prey species as the other two seabirds' diets: the Royal Tern's diet included 36 species of fishes, in 20 families, and pelagic squat lobster Grimothea planipes, whereas the Elegant Tern and …


Evidence For Colony Attendance By Immature Streaked Shearwaters Calonectris Leucomelas During The Chick-Rearing Period., Helen M. Pružina, Akiko Shoji, Masaki Shirai, Sakiko Matsumoto, Ken Yoda, Annette L. Fayet Aug 2026

Evidence For Colony Attendance By Immature Streaked Shearwaters Calonectris Leucomelas During The Chick-Rearing Period., Helen M. Pružina, Akiko Shoji, Masaki Shirai, Sakiko Matsumoto, Ken Yoda, Annette L. Fayet

Marine Ornithology

Many seabird species have a long breeding-deferral period, during which individuals mature and spend most of their time at sea, making them particularly difficult to study. In some species, immatures are known to start visiting colonies before reaching adulthood, presumably to learn the behaviours required to secure a nest and mate for future breeding. However, immature colony attendance remains undocumented in many species, particularly those that are difficult to observe, such as nocturnal, cavity-nesting species and species in which immatures are indistinguishable from adults. Here, we studied the attendance patterns and behaviour of Streaked Shearwaters Calonectris leucomelas on Awashima Island, …


First Record Of Leucism In Kerguelen Shag Leucocarbo Verrucosus, Kevin Guille Aug 2026

First Record Of Leucism In Kerguelen Shag Leucocarbo Verrucosus, Kevin Guille

Marine Ornithology

The first case of leucism in the Kerguelen Shag Leucocarbo verrucosus was observed on Mayes Island, Kerguelen Archipelago, in the southern Indian Ocean between October 2021 and November 2022. The individual exhibited extensive white plumage with scattered black feathers while maintaining normal eye pigmentation, consistent with leucism rather than albinism. Despite exhibiting typical behavior and social interactions, no breeding activity was recorded. This observation highlights the occurrence of pigment abnormalities in sub-Antarctic seabirds and underscores the importance of continued monitoring to better understand their ecological or genetic implications.
