Sounding The Nile: River Politics, Environment And Nubian Musical Expression, Regan L. Homeyer

Music ETDs

ABSTRACT

In the mid 1960s, almost 100,000 Egyptian Nubians, people Indigenous to the Nile River Valley, were removed from their ancestral homeland due to the creation of the Aswan High Dam. In the years surrounding their displacement, Nubian musicians in Cairo and villages in new settlement areas gathered traditional Nubian songs and composed new songs to form a distinctive Nubian musical repertoire. This thesis addresses contemporary Nubian musical performance and the role of these reclaimed and newly-written songs in maintaining and revitalizing not only Nubian languages and culture, but especially senses of self in relation to place and, above all, …

Current Applications And Limitations Of Forensic Entomology, Helena Volckaert

Themis: Research Journal of Justice Studies and Forensic Science

Forensic entomology is the study of arthropods concerning their application in crime scene investigation as a method of predicting postmortem interval (PMI) in deceased or missing individuals. PMI is determined by the life stage of insects present on-scene. Insects used in criminal investigations are primarily beetles, flies, or moths; this may also include various scavenging insects and hitchhiking mites. These creatures help colonize decayed tissue, providing crime scene personnel with live specimens collected and examined for biological evidence. Forensic entomology is currently a niche application in most investigations—as qualified entomologists are often needed—and proper analysis of collected evidence can be …

Population And Reproductive Dynamics Of Zebra Mussels (Dreissena Polymorpha) In Texas Reservoirs: Predicting The Sustainability Of Zebra Mussel Populations In Warmer Waters, Heather Mae Arterburn

Biology Dissertations - Archive

Zebra mussels (Dreissena polymorpha) are highly invasive freshwater bivalve mollusks, introduced to the United Sates in the late 1980’s, and known for forming dense colonies that can encrust boat hulls and motors, damage docks and marinas, and occlude raw water lines and intake pipes. In 2009, zebra mussels were discovered in Lake Texoma, TX/OK and have since infested twenty other lakes in Texas. Never before have zebra mussels been found in waters as warm as those in Texas, leading scientists, resource managers, and regulatory agencies to question the pervasiveness and persistence of this species in warm southwestern water bodies. To …

Quantification Of Mammalian Circadian Rhythms In Response To Photopollution With A Focus On Splitting Behavior, Mehdi Khan

University Honors Program Senior Projects

Circadian rhythms are generated by internal biological clocks of organisms and are responsible for the synchronization of an organism’s external and internal environment. The cells responsible for conducting and maintaining the circadian system are known to be coupled in order to maintain a harmonic rhythm. Desynchronization of the master circadian rhythm can cause the presence of two or more rhythms to emerge in a single organism, also known as splitting behavior. Photopollution and artificial light is known to disrupt this synchronization and result in a desynchronized or split rhythm. Many studies have highlighted that photopollution can disrupt the biological clock …

Olfactory Tissue Investment In Tropical Rainforest Ants Scales With Body Size., Heather Evon Short

College of Arts & Sciences Senior Theses

Differential tissue allocation in animal sensory systems is common and varies with habitat. Worker ants perform a variety of complex tasks that depend on neural capacity, with chemical cues considered central to ant behavior. The antennal (olfactory) lobes of ant brains are often highly developed relative to other insects; however, arboreal ants that live in environments with higher light levels tend to rely more on visual cues than olfaction compared to terrestrial ants. The extent to which habitat-driven behavior affects neural investment in tropical rainforest ants is unknown. Here, I focused on three common tropical ant species (Pseudomyrmex boopis, P. …

In Vitro Immune Activation By Treponema Pallidum And The Effect On Osteoclastogenesis: First Experimental Step Towards An Integration Between Osteoimmunology And Paleopathology., Emily Ann Rich

College of Arts & Sciences Senior Theses

The presence of pathogens in the human body influences the expression of pro-inflammatory cytokines by activated immune cells. These cytokines, and other factors, regulate osteoclastogenesis and osteoclast activity. Through experimental osteoimmunology, interactions between the inflammatory response and bone cell physiology may provide insight into how immune processes can be translated into the lesions or abnormalities observed in the osteological record. In this research, our objective was to determine if the cytokines produced by activated immune cells increase osteoclastogenesis and osteoclast activity. To evaluate this hypothesis, we used two main protocols, one for immune activation and one for osteoclastogenesis, that utilized …

Meta-Analysis Of Biological Research Literature, Evan Suggs

Honors Theses

Comparative studies have been powerful tools in generating a broad understanding about the evolution of animal social systems but they currently rely on the slow, manual process of reading thousands of abstracts and papers from research databases. A web application was created for researchers conducting a comparative survey, in order to speed up their research. This web application automates the retrieval of research papers and their selection process. Using previously obtained data sets on the orders Artiodacytla and Lagomorph, a machine learning application was created to classify the papers. These techniques and tools should greatly increase the speed at which …

Body Composition Of Female Collegiate Track And Field Athletes, Adelaide Cooke

Biological Sciences

The aim of this study is to see if there is a correlation between an athlete's body compostion and the demands of their different track and field events. Track and field is arugably the most diverse when it comes to body types in a single sport, with distance runners tending to be leaner and smaller and throwers more muscular and larger. However, most data collected is not female specfic. Thirty-one female track and field athletes were asked to take part in a series of physical measurements, which included recording their height, weight, percent body fat, and muscle mass. They were …

A Tale Of Two Species: Black-Tailed And White-Tailed Prairie Dog Biogeography From The Last Interglacial To 2070, April Dawn Bledsoe

Electronic Theses and Dissertations

Ecological niche models (ENMs) were created for White-tailed and Black-tailed prairie dogs and projected into the Last Interglacial (LI), the Last Glacial Maximum (LGM), and mid-Holocene (mid-H) to discern possible past suitable habitat for both species. Additionally, ENMs were projected into the future year 2070 representative concentration pathways (RCPs) 2.6 and 8.5 to discern how climate change may affect future habitat suitability. Kernel density estimations, minimum convex polygons, and median distribution centers of White-tailed and Black-tailed occurrence records were examined between time-periods to discern the effects of anthropogenic westward expansion on both species’ distributions. Current ENMs were constructed from commonly …

A Review Of The Characteristics Of Super-Utilizers And Evidence-Based Approaches To Reduce Healthcare Utilization, Suswara Mandala Rayabandla

Capstone Experience: Master of Public Health

A significant fraction of health care resources in the United States of America is utilized by a comparatively small number of people. An examination of the attributes and patterns and associated evidence-based interventions for such high-utilizing patients might aid clinicians to improve interventions to address the distinctive needs of these patients, decrease their risks for numerous hospitalizations, and contribute to reducing the costs. This study aims at exploring the existing literature on the characteristics of super-utilizers and interventions to reduce avoidable use of health care among this population. The method used for this research is a comprehensive literature review. Search …

Characteristics And Spatial Heterogeneity Of Prescribed Fire Behavior In North Dakota Grasslands, Megan Elizabeth Zopfi

Theses and Dissertations

Fire is a critical physical and chemical process required to sustain many grassland ecosystems. In North America, observations of grassland fire behavior in warm-season, southern grasslands are commonly used in fire behavior modeling efforts across the Great Plains. However, grasslands of the northern Great Plains contain a greater component of cool-season vegetation that may generate different fire behavior. To further our understanding of prescribed fire behavior in North Dakota grasslands, we quantified fuel, weather, and fire behavior characteristics associated with 27 prescribed fires conducted across three sites in North Dakota. We sampled 27 points on each fire arranged into a …

The Landscape As A Unit For Rangeland Inventory In Arid And Semi-Arid Regions Of Iran (Case Studies: Touran Biosphere Reserve And Behkadaye Rajinia Development Project), Mansour Mesdaghi

IGC Proceedings (1977-2023)

Severe land fragmentation, degradation, and pollution problems will force us to think about a rural community and research group in Iran to combine our experiences and skills to deal with the challenges of improving land use sustainability (Bosch at el.1995; Mesdaghi, 1993). Planning rangeland inventory requiring recognition of the ecological processes operating at different scales and their particular characteristics (Friedel and Laycock, 1995).

In ancient countries like Persia (Iran), past land use suggests that rangelands exploitation by local herders was co-adapted with natural environments (Nyerges, 1980; Mesdaghi, 1993). Iranian rangelands, however, were nationalized through the land reforming and the …

Effect Of Different Music Genres On Cognitive Task Performance After High Intensity Interval Training, Derek Jones

Longwood Senior Theses

The effects of high intensity exercise on cognitive performance are not fully understood. Music can affect physiological responses to exercise which may also impact cognitive performance. The aim of this study was to determine if music could impact cognitive performance after a bout of high intensity exercise. METHODS: Twelve subjects (n=7 males, n=5 females, 20.3 ± 1.7 y; 72.2 ± 14.9 kg; 1.70 ± 0.09 m) completed the Stroop test after a short (12 min) bout of high intensity interval exercise while listening to either Classical, Rock, or No Music. Subjects completed the Brunel Music Rating Inventory after listening to …

How Do Farmers Experience Agroecology In Rural Communities Of Northern Ecuador?, Neil Michael Ayala Ayala

Latin American Studies ETDs

Agroecology, a concept in continuous evolution embraces science, practice and sociopolitical aspects. Its meaning is gaining space of debate and global interest as an alternative for building sustainable food systems and resilient communities, not only from the environmental perspective, but from all the dimensions of sustainability. The Andes region is recognized for its agrodiversity and for its history of agricultural activity; nevertheless, the effects of unsustainable agricultural practices inspired in the principles of the so called “Green Revolution” are evident. Conventional agriculture has decreased the capacity of resilience of the agroecosystems and their associated communities. Agroecology is often perceived as …

Wai Puna: An Indigenous Model Of Māori Water Safety And Health In Aotearoa, New Zealand, Chanel Phillips Ph.D.

International Journal of Aquatic Research and Education

Māori (the indigenous peoples of Aotearoa, New Zealand) are intimately connected to wai (i.e., water) yet are overrepresented in New Zealand’s drowning statistics each year. On average Māori account for 20-24% of all preventable and non-preventable drowning fatalities, despite comprising only 15 percent of New Zealand’s population. Drowning remains a significant issue posing a threat to whānau (i.e., families) through premature death being imminent and whakapapa (i.e., genealogy) being interrupted. There is limited research that has examined Māori and indigenous understandings of water safety within the literature and limited studies that have investigated the issue of Māori drowning from a …

Inconceivable: An Analysis Of Assisted Reproductive Technology For The Church, Mary Elizabeth Gresham

Senior Honors Theses

Infertility pushes the boundaries of emotional and physical health, which is why many couples inside and outside the church turn to Assisted Reproductive Technology (ART) for a solution. Despite what has seemed like silence from the Church, some individuals have braved the biological confusion and ethical dilemmas to evaluate the technology. Three major ethical viewpoints have emerged that each prioritize something over medical technology, namely community, order, or human dignity. This paper serves to educate pastors and church leaders on the ever-changing biology of ART as well as give voice to Christians that have spoken out on this issue. At …

Evolutionary Bioethics Advanced By Ernest Everett Just: Implications For Biology, Ethics, And Theology, Theodore Walker

Perkins Faculty Research and Special Events

Ernest Everett Just (1883-1941) is an acknowledged “pioneer” in biology, being honored with a Black Heritage postage stamp in 1996. Here we discover that Just also made pioneering contributions to general evolutionary bioethics (distinct from special medical bioethics) by advancing a cell-biology-rooted theory of the origin and continuing evolution of ethical behavior influenced by the “law of environmental dependence.”

See especially “The Origin of Man’s Ethical Behavior (1941, unpublished book manuscript) by Ernest Everett Just and Hedwig Schnetzler Just, discovered in 2018 among the collected papers of E.E. Just at the Moorland-Spingarn Research Center at Howard University.

Accordingly, evolution is …

Cultural Bastions, Farm Optimisation And Tribal Agriculture In Aotearoa (New Zealand), Tanira Kingi

IGC Proceedings (1977-2023)

This paper outlines the influence of cultural factors (including tradition knowledge systems) on tribal agricultural organisations in Aotearoa-New Zealand (NZ); and then presents a conceptual framework that integrates several existing models and tools designed specifically for Māori farmer collectives. Traditional knowledge systems have a pervasive influence on NZs Māori agribusiness sector. However, they often go unrecognised; concealed beneath a land tenure system and legislative framework that is restrictive, cumbersome and has been responsible for widespread land loss since its introduction almost 150 years ago. In spite of these constraints, Māori agriculture in NZ is vibrant, diverse and has several unique …

The Community Influence Of Sponge And Coral Aquaculture In Zanzibar, Hanna Gaertner, Asma Ahmada Hamad, J. Richard Walz

DU Undergraduate Research Journal Archive

Aquaculture has been presented as a means of income for coastal communities, particularly in the context of climate change and resource exploitation. The NGO Marine Cultures in Jambiani, Zanzibar has established a sponge cultivation program for women in response to declining feasibility of seaweed farming from warming ocean temperatures. In addition, the organization strives to restore a severely damaged reef while providing employment for coral farmers and tour boat operators. This study analyzed the influence of aquaculture on community stakeholders, primarily with respect to sponge cultivation and secondarily in regard to coral farms. Using Marine Cultures as a case study, …

Application Of Pastoralists' Knowledge To Natural Resource Management In Spain, Elisa Oteros-Rozas, María Fernández-Giménez, Ricardo Ontillera-Sánchez, José A. González, Federico Fillat-Estaque

IGC Proceedings (1977-2023)

Extensive livestock rearing has been acknowledged as an important tool for sustainable management of social-ecological systems and biodiversity conservation. In the Mediterranean Basin this relationship has been highlighted in mountainous and rural areas, where the co-evolved assemblages and dynamics of plant communities and grazing practices and patterns are mutually reinforcing. Among extensive livestock rearing systems, mobile pastoralism is a typical adaptation in semi-arid areas and mountainous regions where pasture availability is especially variable in time and space. In Spain, mobile pastoralism dates back to Neolithic and has survived until our days in different ways. An outstanding example of mobility is …

Outperformed: Exploration And Comparison Of The Tongue-And-Cheek Tragedies Of Women-Animal Relationships In Selected Short Stories By Samanta Schweblin And In Apichatpong Weerasethakul’S Film, Uncle Boonmee Who Can Recall His Past Lives, Sawnie Smith

Vernacular: New Connections in Language, Literature, & Culture

The unsettling short stories that comprise Samanta Schweblin’s 2008 collection Pájaros en la boca are textured and populated by the flesh of not only humans, but also the skins of species that belong to a wider zoological and mythical scope. Those creatures in Schweblin’s literary output who possess scales, feathers, and wings find themselves variously rubbing up against, crushed under, and orally engulfed by human dermis. This essay seeks to explore the charge of gender politics that courses through interactions between human women and (demi-) animals in two short stories from this collection: “El hombre sirena” and “Olingiris”—animal contact with …

Understanding Stem Instructors’ Experiences With And Perceptions Of Deaf And Hard Of Hearing Students: The First Step Towards Increasing Access And Inclusivity, Makayla Long

Honors Theses

Through an anonymous survey we analyzed Western Michigan University (WMU) STEM instructors’ experience with and understanding of teaching and interacting with Deaf and Hard of Hearing (HoH) students. The goal of this study was to capture the experiences of WMU STEM instructors and the resources available to them given their direct impact on Deaf/HoH students’ ability to succeed and receive a post-secondary education. The findings of this study support the claim that instructors are not well supported or aware of the needs of Deaf/HoH students, and do not have access to adequate resources to resolve the issue.

What Smells? Developing In-Field Methods To Characterize The Chemical Composition Of Wild Mammalian Scent Cues, Cynthia Thompson, Kimberly N. Bottenberg, Andrew W. Lantz, Maria A B De Oliveira, Leonardo C O Melo, Christopher J. Vinyard

Peer Reviewed Articles

Olfactory cues play an important role in mammalian biology, but have been challenging to assess in the field. Current methods pose problematic issues with sample storage and transportation, limiting our ability to connect chemical variation in scents with relevant ecological and behavioral contexts. Real-time, in-field analysis via portable gas chromatography–mass spectrometry (GC-MS) has the potential to overcome these issues, but with trade-offs of reduced sensitivity and compound mass range. We field-tested the ability of portable GC-MS to support two representative applications of chemical ecology research with a wild arboreal primate, common marmoset monkeys (Callithrix jacchus). We developed methods …

Grass-Based Health, Peter Ballerstedt

IGC Proceedings (1977-2023)

A true discussion of sustainability must focus on improving the condition of humanity. Too often, however, such a discussion is a "dialogue of values that defies consensual definition" (Ratner 2004), with participants implicitly accepting as true numerous foundational beliefs that are factually incorrect or unproven. Dietary policies recommending carbohydrate-based diets are one example. Falsehoods persist despite decades of contradictory re-search results and clinical findings, contaminating a variety of diverse disciplines and discussions. A rational, objective discussion of sustainability in grassland agriculture must confront the issue of public health policy, consider our physical health, the fiscal health of our communities, and …

Spider Fauna (Araneae: Araneomorphae) In Natural Grasslands Of Uruguay With Different Livestock Management, Álvaro Laborda, Rafael A. Tosi-Germán, Sebastián Donate, Oscar Blumetto

IGC Proceedings (1977-2023)

In Uruguay natural grasslands sustain cattle ranching and are the country’s main renewable resource. This ecosystem not only serves a productive function, but also functions in geophysical processes of soils and sustaining the nation’s biodiversity through complex trophic webs (Berretta 2009). Increased pressure from human activities that exploit natural resources makes it necessary to possess tools for detecting disturbances in ecosystems and assessing their conservation status. Identifying indicator taxa is essential for evaluating the degree of impact on natural grasslands and for applying this in the development of management plans for this habitat type (Avalos et al. 2007; Cardoso …
