Why The Recognition Of Sentience Is So Important For Animal Welfare, Mark Jones

Animal Sentience

Rowan et al. (2022) provide a useful summary of the history and development of the philosophical, public, and legal recognition of animal sentience and its importance in improving the welfare of animals. Here I argue for the incorporation of the precautionary principle in sentience recognition, and the wider significance of sentience recognition to the current climate, biodiversity and human health crises.

First Contribution To Labiobaetis Novikova & Kluge In Cambodia (Ephemeroptera, Baetidae), With Description Of Two New Species, Thomas Kaltenbach, Jhoana M. Garces, Jean-Luc Gattolliat

Biology Faculty Publications

Material collected in 2018 in Cambodia gives us first insights into the diversity of Labiobaetis Novikova & Kluge, 1987 in this country. No species has been reported so far. We identified two new species using a combination of morphology and genetic distance (COI, Kimura 2-parameter). They are described and illustrated based on their larvae. A key to all Labiobaetis species of continental Southeast Asia is provided. The interspecific K2P distance between the two new species is 20–21%, the intraspecific distance of one of them is 1%. The total number of Labiobaetis species worldwide is augmented to 156.

Selected Dietary Plant-Based Proteins For Growth And Health Response Of Nile Tilapia Oreochromis Niloticus, Tzodoq O. Magbanua, Janice A. Ragaza

Biology Faculty Publications

Tilapia culture is one of the largest sectors of global aquaculture. Among the different species of tilapia, Nile tilapia (Oreochromis niloticus) is perhaps the top cultured species. The production of Nile tilapia has been continually increasing throughout the years resulting in genetic deterioration. Several tilapia strains with better growth performance and adaptive capability to survive in different culture conditions have been developed to alleviate the crisis. Increased demand for Nile tilapia implies higher farming cost. Plant-based proteins are utilized as partial or complete fishmeal replacements to reduce feed cost. However, these proteins can adversely affect and alter growth …

Transitions In Bacterial Communities Across Two Fermentation-Based Virgin Coconut Oil (Vco) Production Processes, Zomesh A N Maini, Crisanto M. Lopez

Biology Faculty Publications

Despite being one of the most used methods of virgin coconut oil (VCO) production, there is no metagenomic study that details the bacterial community shifts during fermentation-based VCO production. The identification and quantification of bacteria associated with coconut milk fermentation is useful for detecting the dominant microbial genera actively involved in VCO production which remains largely undescribed. Describing the constitutive microbial genera involved in this traditional fermentation practice can be used as a preliminary basis for improving industrial practices and developing better fermentation procedures. In this study, we utilized 16S rRNA metagenomic sequencing to trace the transitions in microbial community …

Psychological Predictors Of Advanced Cancer Patients' Preferences For Return Of Results From Comprehensive Tumor Genomic Profiling, Bettina Meiser, Phyllis Butow, Grace Davies, Christine Napier, Timothy Schlub, Nicci Bartley, Ilona Juraskova, Mandy Ballinger, David M. Thomas, Kathy Tucker, David Goldstein, Barbara Biesecker, Megan Best

IES Papers and Journal Articles

This study assessed the psychological predictors of preferences for return of comprehensive tumor genomic profiling (CTGP) results in patients with advanced cancers, enrolled in the Molecular Screening and Therapeutics Program. Patients completed a questionnaire prior to undergoing CTGP. Of the 1434 who completed a questionnaire, 96% would like to receive results that can guide treatment for their cancer, and preference for receiving this type of result was associated with lower tolerance of uncertainty. Sixty-four percent would like to receive results that cannot guide treatment, and lower tolerance of uncertainty, self-efficacy, and perceived importance were associated with this preference. Fifty-nine …

Wild Animal Welfare, Clare Palmer, Peter Sandøe

Animal Sentience

Rowan et al’s article provides an overview of developments in the science of animal sentience and its links to animal welfare policy, especially regarding farm animals. But changing ideas of animal sentience and welfare are also important for managing wild and other free-living animals. We ask how the welfare of these animals differs from that of farmed animals, especially how the ability to make autonomous choices may matter. We suggest that more research into wild animal welfare is needed to make informed policy decisions, for example, about using animals in rewilding projects and choosing between policies of culling and fertility …

Teacher Perceptions Of Disproportionate Suspensions Between Minority And White Students, Tanika Rachelle Barr

Walden Dissertations and Doctoral Studies

Throughout public schools in the United States, minority students continue to receive more disciplinary consequences compared to other groups of students. The problem addressed in this study was the persistence of discipline disproportionality between minority students and White students at a public U.S. middle school, even with recent efforts such as the implementation of the positive behavior interventions and supports (PBIS) framework. Guided by the theory of behaviorism, the purpose of this basic qualitative study was to investigate teachers’ perceptions about the persistence of this discipline disproportionality between minority and White students and ways to improve the use of PBIS …

Fortitude, Spiritual Fortitude, And The Cancer Care Continuum In African American Breast Cancer Survivors, Karen Y. Boone

Walden Dissertations and Doctoral Studies

African American breast cancer survivors (AABCS) struggle with physical, emotional, psychological, spiritual, and financial challenges. Navigating these challenges can require the use of inner resources such as fortitude and spiritual fortitude. Using Folkman and Lazarus’ transactional model of stress and coping as the theoretical framework, the purpose of this study was to examine fortitude and spiritual fortitude as coping responses by African American women living with breast cancer and whether fortitude and spiritual fortitude were associated with phases of the cancer care continuum. A quantitative nonexperimental cross-sectional design was used for primary data collection that involved using Pretorius’ Fortitude Questionnaire …

Georgia Public Fire Investigators’ Behavioral Approach To Fire Scene Investigation, Kyle R. Bradshaw

Walden Dissertations and Doctoral Studies

Wrongful prosecutions for the crime of arson are occurring. An identified cause of this problem is the investigation processes used by public fire investigators. The purpose of this general qualitative study was to identify the targeted behaviors that influence public fire investigators when conducting fire scene investigation. Street-level bureaucracy theory indicates public fire investigators are street-level bureaucrats (SLBs). The intent of this study was to identify behavioral interventions that can be implemented to aid public fire investigators in their approach to fire scene investigation. Semistructured interviews were conducted with a purposeful sample of 10 public fire investigators in a metropolitan …

Mothers’ Perceptions Of Quality Of Life After A Prison Nursery Program, Gwendolyn D. Burke

Maternal Identity Of Modern-Day Mothers With High Identity Centrality, Kimberly Dianne Anderson

Walden Dissertations and Doctoral Studies

The purpose of this qualitative study was to explore conceptualization of maternal identity among mothers with high identity centrality in suburban Virginia. The role of motherhood is culturally recognized as central to female identity, which historically has been described, defined, and maintained through various forms of media. This study involved using the social identity and self-categorization theories as explanatory frameworks to address development and maintenance of maternal identity. A qualitative approach was used to explore identity centrality and conceptualization of maternal identity with a purposefully sampled group of 10 mothers. Data were collected via demographic surveys followed by one-on-one semi-structured …

Staff Education To Improve Knowledge About Suicide Screening, Cidia Alysia Awyie

Walden Dissertations and Doctoral Studies

AbstractHealthcare workers play an essential role in healthcare facilities to help patients with mental health challenges and those at risk of committing suicide. The practice gap that the healthcare facility was experiencing was a knowledge deficit among healthcare staff on the importance of suicide screening. The importance of equipping staff with suicide screening knowledge is to help decrease suicide attempts, suicide thoughts, and completed suicide in patients. The practice-focused question for this staff education project asked if staff education for nursing staff and psychiatrists would increase their knowledge about suicide prevention methods and suicide screening techniques. The purpose of the …

Investigating The Relationship Between The Microbiome And Neuroactive Metabolites In Huntington Disease Model Mice, Christian Millot

Electronic Theses and Dissertations, 2020-2023

Huntington Disease (HD) is an autosomal dominant neurodegenerative disorder caused by a trinucleotide repeat expansion mutation in the huntingtin (HTT) gene. HD is characterized by neurological symptoms, including motor, cognitive, and psychiatric decline. A non-neurological symptom, metabolic dysfunction, is also common in HD and can cause weight change, a feature recapitulated in HD mice. There is a need for a better understanding of the weight changes associated with HD, because patients with a higher body mass index show slower disease progression. Our lab has shown that metabolic dysfunction in HD mice is the result of a disrupted circadian feeding rhythm …

Investigation Of Realism In Facial Characteristics And Anthropomorphic Language In The Design Of Multimedia Instruction, Ecem Olcum

Electronic Theses and Dissertations, 2020-2023

Emotional design elements have recently been added to the research in cognitive load and multimedia learning (Um et al., 2012). One aspect of eliciting positive emotions is to use anthropomorphic design, which has been found to increase learning performance (Um et al., 2012; Plass et al., 2014; Park et al., 2015; Schneider et al., 2018). The current research aimed to investigate three design factors in three studies: anthropomorphism in verbal and visual design, single-frame or multi-frame illustrations, and realism of the anthropomorphic visual design. The first study confirmed that the anthropomorphic verbal and visual materials were perceived as anthropomorphic by …

Role Of Biological Clocks In Ant Behavioral Plasticity And Parasitic Manipulation Of Ant Behavior, Biplabendu Das

Electronic Theses and Dissertations, 2020-2023

Living organisms exhibit daily rhythms as a way to anticipate predictable fluctuations in their environment. Such daily rhythmicity is the phenotypic outcome of oscillating genes and proteins, driven by an endogenous biological clock. Clock-controlled behavioral rhythms are inherently "flexible" since their phase, amplitude, and period can change throughout an animal's life hallmarked by changes in so-called chronotype. How this inherent plasticity of clock-controlled rhythms is linked to plasticity of behavior is still an open question in biology. Characterizing the various mechanistic links between plasticity of the animal clock and behavioral state will not only shed light on the molecular underpinnings …

An Examination Of Gender-Based Differences In Perceptions Of Supervisor Support, Ann Schlotzhauer

Electronic Theses and Dissertations, 2020-2023

Perceived supervisor support and particularly emotional support possess conceptual overlap with stereotypes of femininity. The present study extends understanding of perceived supervisor support by applying the agency and communality framework of gender stereotypes and role congruity theory. This study employed a vignette research design to examine differential ratings of male and female supervisors who were depicted engaging in (a) no support, (b) instrumental support, (c) emotional support, or (d) instrumental and emotional support. Results suggest that supportive supervision is indeed viewed as feminine in nature. Further, findings suggest that female supervisors engaging in emotional support behaviors are preferred over equivalently …

Juvenile Dispersal And Genetic Connectivity In The Sea Turtle 'Lost Years', Katrina Phillips

Electronic Theses and Dissertations, 2020-2023

Juvenile dispersal is a life history strategy found across taxa and habitat types. In this dissertation, I examine juvenile dispersal in an evolutionary context and explore the conditions that support high dispersal, which necessitates subsequent ontogenetic habitat shifts. I use a sea turtle study system to evaluate the genetic and behavioral patterns associated with juvenile dispersal and ontogenetic shifts in marine environments. Specifically, I focus on four sea turtle species found in the northeastern Gulf of Mexico in the early life stage known as the 'lost years': green turtles (Chelonia mydas), Kemp's ridleys (Lepidochelys kempii), loggerheads (Caretta caretta), and hawksbills …

Non-Invasive Detection Of Elevated Intracranial Pressure Using Spontaneous Tympanic Membrane Pulsation, Rajkumar Dhar

Electronic Theses and Dissertations, 2020-2023

Monitoring intracranial pressure (ICP) is a standard diagnostic tool for various neurological conditions such as head injury, ruptured aneurysms, intracerebral and intracranial hemorrhage, and hydrocephalus. Currently, ICP monitoring relies on invasive pressure measurements. These include intraventricular catheter, subdural screw, epidural sensor, and lumbar puncture. Invasive methods pose the risk of infection and hemorrhage, are expensive, and require special clinical skills. A noninvasive method that is reliable, simple to use, low-cost, and provides easily interpretable results can help avoid the complications associated with the invasive methods. This study proposes a novel method for noninvasive ICP monitoring using tympanic membrane pulsation (TMp). …

A Measurement System For Detection Of Intestinal Motility In Neonates By Monitoring Slow Wave Activity, Garett Goodale

Electronic Theses and Dissertations, 2020-2023

Similar to how electrocardiographic waves are the pace making signals of the heart, slow waves are the pace making signals of the intestines. Slow waves are electrical signals in the intestines that determine the speed at which food can move through the intestine ensuring proper digestion and uptake of nutrients. It has been shown that slow waves can be measured in adults using non-invasive, surface electrodes. However, no study has investigated the measurements of slow waves in neonates, specifically pre-term neonates. Around 7% of pre-term neonates suffer from necrotizing enterocolitis (NEC) which is a condition that causes damage to the …

Trauma And Resilience Among Migrant Children From Mexico And The Northern Triangle En Route To The United States, Georgina Sanchez Garcia, Mark Lusk, Paula Chavez Santamaria

The Journal of Sociology & Social Welfare

Children who are forced to migrate to flee violence, extreme poverty, and natural disasters are exposed to trauma in their countries of origin and on the migrant trail. Forced child migrants from Central America and Mexico who flee to the U.S. border are particularly vulnerable. In this qualitative study, we interviewed 76 migrant children from Mexico, El Salvador, Honduras and Guatemala. We listened to their stories and assessed exposure to adverse events, traumatic stress and child resiliency. While children experienced adversity and trauma, they were protected by high levels of resiliency that is grounded in family, faith, courage and camaraderie.

Elucidating The Role Of Polycomb Repressive Complex 2 In Lung Stem Cell Fate And Lung Disease, Aria Byrd

Theses and Dissertations--Toxicology and Cancer Biology

The average human lungs take ~22,000 breaths and inhale ~2,000 gallons of air each day. This organ is the primary conduit for the transfer of oxygen to the internal organs, making it crucial for the sustainment of life. Consequently, mechanical malfunction of the lungs and/or pollution of inhaled air negatively impact internal organ function and ultimately put survival in jeopardy. Epigenetics, by nature, is a plastic phenomenon in which environmental stimuli influence short term, long term, and generational gene expression patterns. Chronic exposure of harmful stimuli to the lung epithelium has also been shown to alter epigenetic pathways, engender aberrant …

Extracellular Vesicles And Cancer Therapy: An Insight Into The Role Of Oxidative Stress, Jenni Ho

Theses and Dissertations--Toxicology and Cancer Biology

As a result of improvements in cancer detection and treatment methods, a growing population of cancer survivors are living with side effects associated with their cancer therapy. Oxidative stress plays a significant role in the development of cancer and as a mechanism for cancer therapy to exert its therapeutic effects, resulting in off-target tissue damage. Radiation has been long established as a means to utilize the generation of reactive oxygen species to kill cancer cells, and 50% of chemotherapy agents currently used are associated with inducing oxidative stress. One major side effect observed in cancer survivors is a decline in …
