There can be several factors that are likely to have played a role in the evolution of hand preference in humans and non-human primates, which the existing theories do not consider. There exists a possibility that hand preference in non-human primates evolved from the pre-existing lateralities in more elementary brain functions and behavior, or alternatively, the two coevolved. A basic example can be a hand-mouth command system that could have evolved in the context of ingestion. In the present study, we examined the relationship between lateralities in prehension and mastication processes, that is, hand and cheek pouch usage, in free-ranging …

PCB signatures can be used for source identification, exposure studies, age dating and bio-monitoring. This study uses comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCxGC-ToFMS) to produce a PCB signature comprised of over 80 PCBs for individual Leach's storm petrels (Oceanodroma leucorhoa). The Leach's storm petrel is a relatively small, elusive, understudied pelagic bird, which only returns to remote islands under darkness during the breeding season. Samples were obtained from 25 Leach's storm petrels found dead in Canada and the UK following storm events in 2006 and 2009. Tissue samples were extracted and analysed by GCxGC-ToFMS and results showed …

Open Access Author Fund Awardees' Articles
Theta (6–12 Hz) rhythmicity in the local field potential (LFP) reflects a clocking mechanism that brings physically isolated neurons together in time, allowing for the integration and segregation of distributed cell assemblies. Variation in the theta signal has been linked to locomotor speed, sensorimotor integration as well as cognitive processing. Previously, we have characterized the relationship between locomotor speed and theta power and how that relationship varies across the septotemporal (long) axis of the hippocampus (HPC). The current study investigated the relationship between whole body acceleration, deceleration and theta indices at CA1 and dentate gyrus (DG) sites along the septotemporal …

Understanding how animals alter habitat use in response to changing abiotic conditions is important for effective conservation management. For bull sharks (Carcharhinus leucas), habitat use has been widely examined in the eastern and western Gulf of Mexico; however, knowledge of their movements and the factors influencing them is lacking for populations in the more temperate north-central Gulf of Mexico. To examine how changes in hydrographic conditions affected the presence of young bull sharks in Mobile Bay, Alabama, thirty-five sharks were fitted with internal acoustic transmitters and monitored with an acoustic monitoring array consisting of thirty-three receivers between June …

ZnO nanoparticles (NP) are extensively used in numerous nanotechnology applications; however, they also happen to be one of the most toxic nanomaterials. This raises significant environmental and health concerns and calls for the need to develop new synthetic approaches to produce safer ZnO NP, while preserving their attractive optical, electronic, and structural properties. In this work, we demonstrate that the cytotoxicity of ZnO NP can be tailored by modifying their surface-bound chemical groups, while maintaining the core ZnO structure and related properties. Two equally sized (9.26 ± 0.11 nm) ZnO NP samples were synthesized from the same zinc acetate precursor …
Cloning And Characterization Of Has-Mir-130b: A Regulator Of Pre-Mrna Splicing Factors, Imani Bethel
Cloning And Characterization Of Has-Mir-130b: A Regulator Of Pre-Mrna Splicing Factors, Imani Bethel
Theses (Pre-2016)
Alternative pre-rnRNA splicing contributes to protein diversity and protein expression of aberrantly spliced mRNA contributes to human diseases. Many splicing regulators have been identified and studied, but RNAs that regulate these splicing regulators have not been fully elucidated. One of the RNAs that regulates the splicing regulators is the non-coding RNA, the homo sapien microRNA (hsa-miR-130b). To understand the function(s) and effects of non-coding RNAs on aberrant mRNA splicing regulators, we identified in the literature a gene, Gemin5, an important component pre mRNA splicing regulators. We searched the miR Base database and identified a microRNA (miRNA), hsa-miR-130b, that target mRNA …

Theses (Pre-2016)
Restaurants today have been the leading causes of obesity in America. Despite the fact that a lot of restaurants serve unhealthy food, customers become even lazier by having the ability to drive through to pick up food without the need to leave their vehicles. Statistics show that 64 percent of people in America are overweight. In today's society, there are many families where both parents work eight hour shifts, five days week and do not have time to prepare meals, so they go to fast food restaurants. As a result, fast food restaurants have become increasingly growing franchises. Majorities of …

Redefining Blackness In The Age Of Whiteness: Mimicry, Ancestry, Gender Performance, And Self-Identity In Afro-Caribbean And Afro-American Literature, Brandon Marcell Erby
Seton Hall University Dissertations and Theses (ETDs)
The elements associated with mimicry and colonialism are found in Elizabeth Nunez’s Prospero’s Daughter (2006), as the novel reveals how colonized subjects use mimicry to survive their colonized spaces. Keeping in mind the ideologies of Homi Bhabha and Wumi Raji, the novel also suggests how a subject’s pre-existing condition before being colonized develops agency. Comparably, while Elizabeth Nunez’s novel illustrates how imitation is used by black and native Caribbeans, Richard Wright’s Native Son (1940) and Lorraine Hansberry’s A Raisin in the Sun (1958) contextualize and exhibit W.E.B. Du Bois’s double-consciousness theory and the struggles that black Americans experience while mimicking …
Joint Phenotypes, Evolutionary Conflict And The Fundamental Theorem Of Natural Selection, David C. Queller
Joint Phenotypes, Evolutionary Conflict And The Fundamental Theorem Of Natural Selection, David C. Queller
Biology Faculty Research
Multiple organisms can sometimes affect a common phenotype. For example, the portion of a leaf eaten by an insect is a joint phenotype of the plant and insect and the amount of food obtained by an offspring can be a joint trait with its mother. Here, I describe the evolution of joint phenotypes in quantitative genetic terms. A joint phenotype for multiple species evolves as the sum of additive genetic variances in each species, weighted by the selection on each species. Selective conflict between the interactants occurs when selection takes opposite signs on the joint phenotype. The mean fitness of …

Farming: It's Not Just For Farmers Anymore, Jennifer Schmidt
Pomona Senior Theses
Agricultural education, originally the province of land grant institutions, has recently entered the liberal arts curriculum. This represents a profound shift from the origins of agricultural education, when it was intended primarily as vocational training for future farmers, and has important implications for the future of the American food system. The first chapter of this thesis addresses the history of agricultural education: what was it originally like, and why did it come to be heavily criticized in the late twentieth century? Formal agricultural education changed significantly in response to these criticisms, making it more environmentally sustainable and bringing it into …

California Drought: A Need For Agricultural Revolution In The Golden State, Benjamin Clinkinbeard
2014 Student Theses
California is in a drought State of Emergency, which is fueling negative social and economic consequences. After multiple years of below average rainfall, California has arrived at one of the most severe droughts in recorded history. Climate change is upon the Golden State, and the ugly consequences need to encourage citizens to spur green movements combating environmental destruction. The agriculture industry is in need of drastic change in order to secure a future that includes clean water, and fresh food for a growing population. Currently, the agricultural techniques practiced are far from sustainable. Adopting a new ideal on what it …
The Practice Of Teachers Reading Aloud In The Classroom, John C. Bost
The Practice Of Teachers Reading Aloud In The Classroom, John C. Bost
Education
This inquiry, which involved use of a teacher survey and classroom observations, was designed to explore how teachers use the practice of reading aloud. This small case study, of one urban elementary school in Alaska, also set out to examine how teachers view the practice of a read-aloud. Studies have identified a number of effective components of a read-aloud. This study found teachers in agreement on some important reasons to read aloud and the components of a read-aloud that they value. The teachers in my inquiry appear to value reading aloud and they all share similarities in how they use …

Ultra-Wideband Microwave Ablation Applicators, Mustafa Asili
Theses and Dissertations
The increasing demand for efficient cancer treatment inspired the researchers for new investigations about an alternative treatment of cancer. Microwave ablation is the newest ablation technique to cure cancer. This method is minimally noninvasive and inexpensive compared to the other methods. However, current microwave ablation systems suffer due to narrowband nature of the antenna (dipole or slot) placed at the tip of the probe. Therefore, this study developed an ultra-wideband ablation probe that operates from 300MHz to 10 GHz. For this purpose, a small wideband antenna is designed to place at the tip of the probe and fabricated. These probes …
The Role Of Otolin-1 In Cardiac Matrix Remodeling Following Myocardial Infarction, Courtney Anne Cates
The Role Of Otolin-1 In Cardiac Matrix Remodeling Following Myocardial Infarction, Courtney Anne Cates
Theses and Dissertations
Otolin-1 is a collagenous, C1q domain-containing extracellular matrix protein that has been identified and characterized in the inner ear. Recently, mass spectrometry analysis of left ventricular cardiac tissue detected a peptide of Otolin-1. Experimental analysis confirms Otolin-1 is an insoluble protein present in the left ventricular extracellular matrix whose expression decreases dramatically post-myocardial infarction beginning at day 5 post-MI. The protein is localized to the gap junctions of cardiac myocytes, and depletion of protein levels in the infarcted region of the left ventricle shows strong association with ventricular dimensions, observed via echocardiography.
Use Of Tlingit Art And Identity By Non-Tlingit People In Sitka, Alaska, David Kreiss-Tomkins
Use Of Tlingit Art And Identity By Non-Tlingit People In Sitka, Alaska, David Kreiss-Tomkins
Arctic and Northern Studies
Tlingit culture, as with many Indigenous cultures that exist under colonial rule, is often described as being in danger of disappearing. Despite this, the appropriation of and subsequent use of cultural practices by non-Tlingit people, and especially white people, is a continuation of the process of colonization when it is enacted in a manner that is not critical of current and historical racism, capitalist pressures and colonial violence. This project addresses the topic through recorded conversations with seven Tlingit women in Sitka, Alaska in an attempt to place Tlingit cultural production and use in the broader contexts of Indigenous cultural …
Intermittent Hypercapnia Induces Long-Lasting Ventilatory Plasticity To Enhance Co₂ Responsiveness To Overcome Dysfunction, Bryan Patrick Mosher
Intermittent Hypercapnia Induces Long-Lasting Ventilatory Plasticity To Enhance Co₂ Responsiveness To Overcome Dysfunction, Bryan Patrick Mosher
Biological Sciences
The ability of the brain to detect (central CO₂ chemosensitivity) and respond to (central CO₂ chemoresponsiveness) changes in tissue CO₂/pH, is a homeostatic process essential for mammalian life. Dysfunction of the serotonin (5-HT) mechanisms compromises ventilator CO₂ chemosensitivity/responsiveness and may enhance vulnerability to pathologies such as the Sudden Infant Death Syndrome (SIDS). The laboratory of Dr. Michael Harris has shown medullary raphe' contributions to central chemosensitivity involving both 5-HT- and y-aminobutyric acid (GABA)-mediated mechanisms. I tested the hypothesis that postnatal exposure to mild intermittent hypercapnia (IHc) induces respiratory plasticity, due in part to strengthening of bicuculline- and saclofen-sensitive mechanisms (GABAA …
Induction Of Heat Shock Proteins In Cold- Adapted And Coldacclimated Fishes, Laura Elizabeth Teigen
Induction Of Heat Shock Proteins In Cold- Adapted And Coldacclimated Fishes, Laura Elizabeth Teigen
Biological Sciences
I examined the effects of oxidative stress and changes in temperature on heat shock protein (Hsp) levels in cold-adapted and cold-acclimated fishes. Adaptation of Antarctic notothenioids to cold temperature is correlated with high levels of Hsps, thought to minimize cold-induced protein denaturation. Hsp70 levels were measured in red- and white-blooded Antarctic notothenioid fishes exposed to their critical thermal maximum (CTMax), 4°C warm acclimated, and notothenioids from different latitudes. I determined the effect of cold acclimation on Hsp levels and the role of sirtuins in regulating Hsp expression and changes in metabolism in threespine stickleback, Gasterosteus aculeatus, cold-acclimated to 8°C. Levels …
