Architectural Representations Of Human Rights, El-Bastawissi Y. Ibtihal, Youssef Maged Nov 2022

Architectural Representations Of Human Rights, El-Bastawissi Y. Ibtihal, Youssef Maged

BAU Journal - Creative Sustainable Development

The United Nations defines the Human Rights as the rights of all human beings, regardless of race, gender, language, religion, nationality, or any other status. These rights include all claims to live freely, to educate and work in equality, and to inhabit humanistic urban and architectural spaces. Throughout the history of architecture, civilisations have generated different perspectives towards respecting the human rights. Temples of Ancient Egyptian Architecture crushed the human scale to introduce religious experiences to their visitors. Tibetan temples over mountains enforced people to make anti-humanistic journeys to reach them. After thousands of years, the mega-scale palaces and cathedrals …

Water is essential for survival, but one in three individuals worldwide (2.2 billion people) lack access to safe drinking water. Water intake requirements largely reflect water turnover (WT), the water used by the body each day. We investigated the determinants of human WT in 5,604 people from the ages of 8 days to 96 years from 26 countries using isotope tracking (2H) methods. Age, body size, and composition were significantly associated with WT as were physical activity, athletic status, pregnancy, socioeconomic status, and environmental characteristics (latitude, altitude, air temperature, and humidity). People in countries with low human development index (HDI) …

Combining Isotopic And Genetic Analyses To Quantify Microbial Facilitation Of Recalcitrant Resource Use By Terrestrial And Aquatic Consumers, Alexi Christina Besser

Biology ETDs

Quantifying the flow of energy and nutrients through food webs is foundational to understanding the structure and function of ecosystems. Here, I utilize the stable carbon and nitrogen isotope analysis of individual amino acids to trace the movement of essential amino acids through terrestrial and freshwater food webs in New Mexico, USA. I first explore isotopic patterns among co-occurring terrestrial plants and aquatic algae. I then combine this molecular isotopic approach with 16S and 18S rRNA sequencing to demonstrate the importance of gut microbiota as sources of essential amino acids to wild mammalian hosts. Next, I explore the roles of …


The Conquest Of Milk: The Rise Of Lactase Persistence And The Fall Of Scandinavian Hunter-Gatherers, Nicholas Mays Nov 2022

The Conquest Of Milk: The Rise Of Lactase Persistence And The Fall Of Scandinavian Hunter-Gatherers, Nicholas Mays

James Madison Undergraduate Research Journal (JMURJ)

Over half of the global human population suffers from lactase nonpersistence, a condition marked by losing the ability to digest lactose after infancy. However, a minority of the global population, primarily located in Central and Northern Europe, has a genetic mutation that results in lactase persistence, which is the continued ability to process lactose after infancy. This interdisciplinary analysis blends archaeology, cultural anthropology, evolutionary biology, and archaeogenetics to explore the origin and rise of lactase persistence in Europe and its contribution to the end of hunter-gatherer societies in Scandinavia. Furthermore, the paper uses gene-culture coevolutionary theory to argue that lactase …

Mainframe computers facilitated numerical calculations for exploring relationships among dozens of variables. Personal computers opened the door for more individual scientist creativity and routine communication. Web-based communication globalised the option for multidisciplinary teams to tackle problems. Forage-related computer applications abound, allowing farmers, ranchers, and others to more effectively manage the …


Zebras Of All Stripes Repel Biting Flies At Close Range, Kaia J. Tombak, Andrew S. Gersick, Lily V. Reisinger, Brenda Larison, Daniel I. Rubenstein Nov 2022

Zebras Of All Stripes Repel Biting Flies At Close Range, Kaia J. Tombak, Andrew S. Gersick, Lily V. Reisinger, Brenda Larison, Daniel I. Rubenstein

Publications and Research

The best-supported hypothesis for why zebras have stripes is that stripes repel biting flies. While this effect is well-established, the mechanism behind it remains elusive. Myriad hypotheses have been suggested, but few experiments have helped narrow the field of possible explanations. In addition, the complex visual features of real zebra pelage and the natural range of stripe widths have been largely left out of experimental designs. In paired-choice field experiments in a Kenyan savannah, we found that hungry Stomoxys flies released in an enclosure strongly preferred to land on uniform tan impala pelts over striped zebra pelts but exhibited no …

Department of Biology Faculty Scholarship and Creative Works

Admixture and introgression play a critical role in adaptation and genetic rescue that has only recently gained a deeper appreciation. Here, we explored the geographical and genomic landscape of cryptic ancestry of the endangered red wolf that persists within the genome of a ubiquitous sister taxon, the coyote, all while the red wolf has been extinct in the wild since the early 1980s. We assessed admixture across 120,621 single nucleotiode polymorphism (SNP) loci genotyped in 293 canid genomes. We found support for increased red wolf ancestry along a west-to-east gradient across the southern United States associated with historical admixture in …

Establishing Safe Thresholds To Improve Exercise Capacity In Collegiate Athletes With Inflammatory Bowel Disease (Ibd): A Critically Appraised Topic, Emily C. Roberts, Jenny Toonstra, Andrea Cripps

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Clinical Scenario: Inflammatory Bowel Disease (IBD) can present several challenges to athletic participation due to unpredictable disease activity and uncontrollable systemic symptoms that severely impact daily activities, and limit exercise/sports participation. Limited studies and a lack of standardized guidelines for physical activity (PA) and exercise are additional barriers for patients. Limited sources have determined that exercise interventions of low-to-moderate intensity are safe and feasible for IBD patients. In theory, such interventions could promote improvements in exercise capacity and overall well-being. Focused Clinical Question: Is there evidence to suggest that established safe exercise-intensities promote improvements in exercise capacity in collegiate athletes …


Alu Dimorphism At The Pv92 Locus Of Chromosome 16 Is In Equilibrium For University Student Population, James M. Brooks, Mackenzie L. Thackston Oct 2022

Alu Dimorphism At The Pv92 Locus Of Chromosome 16 Is In Equilibrium For University Student Population, James M. Brooks, Mackenzie L. Thackston

Journal of the South Carolina Academy of Science

Alu is a retrotransposable element, which refers to its ability to be copied and move from one region of DNA to another DNA region. At the PV92 locus of chromosome 16, Alu is a 300 bp dimorphic insert that can either be present or absent. It does not encode a protein product and has lost the ability to transpose. It is specific to humans, and differences in genotype and allele frequencies between human populations are important tools in understanding evolution. In this research, data was obtained and analyzed from 269 students at Charleston Southern University (CSU) belonging to four different …


Speciation Jigsaw Activity, Erika Crispo Oct 2022

Speciation Jigsaw Activity, Erika Crispo

Open Educational Resources

What is a species? Why are there so many species on the planet? The question of why we have different species of organisms was the key thesis of Charles Darwin’s most famous book, On the Origin of Species.While several definitions of what constitutes a species exists, the most common definition lies within thebiological species concept. This concept states that different species exist when two individuals of different sexes are unable to reproduce with one another to yield viable offspring in the wild. A major limitation of this definition is that it can only be applied to sexually reproducing organisms that …

Investigations Into The Negative Impact Of Temperature Stress On Fertility In Wild Strains Of Caenorhabditis Elegans, Nicholas B. Sepulveda Oct 2022

Investigations Into The Negative Impact Of Temperature Stress On Fertility In Wild Strains Of Caenorhabditis Elegans, Nicholas B. Sepulveda

Dissertations (1934 -)

Sexual reproduction and its coincident genetic recombination are powerful adaptive strategies. However, sexual reproduction has disadvantages. One ancient and conserved disadvantage is temperature sensitivity. In organisms diverse as plants, insects, nematode worms, and humans, as temperatures increase, fertility decreases. The goal of this dissertation is to examine the negative impact of elevated temperature stress on fertility in sexually reproducing organisms using wild strains of Caenorhabditis elegans. C. elegans presents a unique opportunity to study these effects broadly in two contexts, as worms may be either self-fertile hermaphrodites that produce both egg and sperm or males which produce only sperm. In …

In mammals, trait variation is often reported to be greater among males than females. However, to date, mainly only morphological traits have been studied. Energy expenditure represents the metabolic costs of multiple physical, physiological, and behavioral traits. Energy expenditure could exhibit particularly high greater male variation through a cumulative effect if those traits mostly exhibit greater male variation, or a lack of greater male variation if many of them do not. Sex differences in energy expenditure variation have been little explored. We analyzed a large database on energy expenditure in adult humans (1494 males and 3108 females) to investigate whether …

Bed Ii Phytolith Palaeolandscapes (1.5-1.1 Ma) At Oldupai Gorge, Tanzania, Makarius P. Itambu Sep 2022

Bed Ii Phytolith Palaeolandscapes (1.5-1.1 Ma) At Oldupai Gorge, Tanzania, Makarius P. Itambu

Tanzania Journal of Science

The primary approach for reconstructing ancient plant landscapes is normally through the analysis of environmental proxy data and ultimately the application of the data from plant micro-remains to infer the vegetation patterns, distribution, and nature of past environments. Phytolith analyses serve as an important tool for identifying different micro-ecological niches in which human activities occurred. They are indicative of certain plant types and vegetation patterns, and the way in which plant landscapes respond to regional climate changes. Hence, in order to understand the ancient plant landscape of the Pleistocene Bed II sites of Oldupai Gorge 1.5 to 1.1 million years …

Chimpanzees (Pan troglodytes) harbor rich assemblages of malaria parasites, including three species closely related to P. falciparum (sub-genus Laverania), the most malignant human malaria parasite. Here, we characterize the ecology and epidemiology of malaria infection in wild chimpanzee reservoirs. We used molecular assays to screen chimpanzee fecal samples, collected longitudinally and cross-sectionally from wild populations, for malaria parasite mitochondrial DNA. We found that chimpanzee malaria parasitism has an early age of onset and varies seasonally in prevalence. A subset of samples revealed Hepatocystis mitochondrial DNA, with phylogenetic analyses suggesting that Hepatocystis appears to cross species barriers more easily than Laverania. …


Proximate And Ultimate Perspectives On Romantic Love Sep 2022

Proximate And Ultimate Perspectives On Romantic Love

The International Journal of Ecopsychology (IJE)

Romantic love is a phenomenon of immense interest to the general public as well as to scholars in several disciplines. It is known to be present in almost all human societies and has been studied from a number of perspectives. In this integrative review, we bring together what is known about romantic love using Tinbergen’s “four questions” framework originating from evolutionary biology. Under the first question, related to mechanisms, we show that it is caused by social, psychological mate choice, genetic, neural, and endocrine mechanisms. The mechanisms regulating psychopathology, cognitive biases, and animal models provide further insights into the mechanisms …


Belonging Amidst Bias: Embracing Difference On The Path To Common Humanity, Alyssia Sheikh Sep 2022

Belonging Amidst Bias: Embracing Difference On The Path To Common Humanity, Alyssia Sheikh

Mindfulness Studies Theses

The mindfulness community prioritizes self-awareness and common humanity, but is often entrapped by the idea that oneness is equivalent to sameness. This inclination for objectivity is rooted in the same neural propensities that facilitate bias; the brain is a subjective organ, however, and so neurologically speaking, bias is inevitable. This paper asks: Is striving for sameness separating us from interconnectedness? A human experience is a subjective, diverse, and variable one. The path to shared humanity and social justice co-occurs with increasing cultural humility through mindful awareness and acknowledging our subjective nature. Exploring our neurological tendency to make assumptions, we …


Natural Striatal Signaling Dynamics During Food Approach, Devry Mourra Sep 2022

Natural Striatal Signaling Dynamics During Food Approach, Devry Mourra

Dissertations, Theses, and Capstone Projects

Reduced dopamine (DA) signaling has been hypothesized to induce compulsive overeating in obesity. However, DA signaling facilitates food pursuit by acting on direct and indirect pathways. This disparity between why individuals compulsively overeat despite decreased DA and satiety signals is unclear. Characterizing how DA and direct/indirect pathways respond to satiation may elucidate how satiety signals become overwritten in obesity. The food's palatability may underlie this, which is putatively thought to override the satiety hormones since it directly increases DA signaling, resulting in the increased appetitive drive. We determined the pattern of dopamine and pathway-specific medium spiny neuron (MSN) activity across …

Great-Tailed Grackles (Quiscalus Mexicanus) As A Tolerant Host Of Avian Malaria Parasites, M. Andreína Pacheco, Francisco C. Ferreira, Corina J. Logan, Kelsey B. Mccune, Maggie P. Macpherson, Sergio Albino Miranda, Diego Santiago-Alarcon, Ananias A. Escalante

Harold W. Manter Laboratory of Parasitology: Library Materials

Great-tailed Grackles (Quiscalus mexicanus) are a social, polygamous bird species whose populations have rapidly expanded their geographic range across North America over the past century. Before 1865, Great-tailed Grackles were only documented in Central America, Mexico, and southern Texas in the USA. Given the rapid northern expansion of this species, it is relevant to study its role in the dynamics of avian blood parasites. Here, 87 Great-tailed grackles in Arizona (a population in the new center of the range) were screened for haemosporidian parasites using microscopy and PCR targeting the parasite mitochondrial cytochrome b gene.

Lower ambient temperature (Ta) requires greater energy expenditure to sustain body temperature. However, effects of Ta on human energetics may be buffered by environmental modification and behavioral compensation. We used the IAEA DLW database for adults in the USA (n = 3213) to determine the effect of Ta (−10 to +30°C) on TEE, basal (BEE) and activity energy expenditure (AEE) and physical activity level (PAL). There were no significant relationships (p > 0.05) between maximum, minimum and average Ta and TEE, BEE, AEE and PAL. After adjustment for fat-free mass, fat mass and age, statistically significant (p < 0.01) relationships between TEE, BEE and Ta emerged in females but the effect sizes were not biologically meaningful. Temperatures inside buildings are regulated at 18–25°C independent of latitude. Hence, adults in the US modify their environments to keep TEE constant across a wide range of external ambient temperatures.

Domesticated ~10,000 years ago in northern China, Proso millet (Panicum miliaceum L.) is a climate-resilient and human health-promoting cereal crop. The genome size of this self-pollinated allotetraploid is 923 Mb. Proso millet seeds are an important part of the human diet in many countries. In the USA, its use is restricted to the birdseed and pet food market. Proso millet is witnessing gradual demand in the global human health and wellness food market owing to its health-promoting properties such as low glycemic index and gluten-free. The breeding efforts for developing improved proso millet cultivars are hindered by the …
