An Unbiased Approach To Identify Genes Involved In Development In A Turtle With Temperature-Dependent Sex Determination, Jena L. Chojnowski, Edward L. Braun

Natural Sciences Faculty Publications

Many reptiles exhibit temperature-dependent sex determination (TSD). The initial cue in TSD is incubation temperature, unlike genotypic sex determination (GSD) where it is determined by the presence of specific alleles (or genetic loci). We used patterns of gene expression to identify candidates for genes with a role in TSD and other developmental processes without making a priori assumptions about the identity of these genes (ortholog-based approach). We identified genes with sexually dimorphic mRNA accumulation during the temperature sensitive period of development in the Red-eared slider turtle (Trachemys scripta), a turtle with TSD. Genes with differential mRNA accumulation in response to …

Markers Of Health Status In Pasture-Fed Versus Total Mixed Ration-Fed Jersey Dairy Cattle, Megan Lee Seneca

Master's Theses and Capstones

Milk from pastured cows contains more beneficial fatty acids than milk from total mixed ration (TMR) fed cows. No studies have been done comparing health status in cows from each system. This study used pastured vs. TMR fed Jersey cows to measure levels of cortisol, haptoglobin (Hp), somatic cells, and production within and between farms over time.

Cortisol was significantly different between farms with means of 126.78 and 93.64 ng/ml for pastured and TMR groups, respectively. Levels in pastured cows trended with temperature and humidity. There was no significant difference in Hp levels between farms though levels did change over …

Observations Initiales Et Finales De Filles Eveillées : Programme Pilote De Renforcement Des Compétences Des Adolescentes Migrantes Employées De Maison. Cohorte 1 (2011–2012), Bobo-Dioulasso, Sarah Engebretsen

Poverty, Gender, and Youth

Le Burkina Faso abrite la dixième population la plus jeune du monde, avec 45% de la population de moins de 15 ans. Les jeunes au Burkina Faso, en particulier les adolescentes, ont peu d'opportunités économiques, en particulier dans les zones rurales. Cela alimente la migration vers les milieux urbaines à la recherche de travail. Seules, les filles sont physiquement et économiquement vulnérables et beaucoup courent un risque élevé de violence sexiste. Le Population Council a mené une recherche formative en 2010 dans le but de mieux comprendre la situation des adolescentes migrantes employées de maison au Burkina Faso urbain, et …

Introducing Environmental Toxicology In Instructional Labs: The Use Of A Modified Amphibian Developmental Toxicity Assay To Support Inquiry-Based Student Projects, Roger Sauterer, James R. Rayburn

Research, Publications & Creative Work

Introducing students to the process of scientific inquiry is a major goal of high school and college labs. Environmental toxins are of great concern and public interest. Modifications of a vertebrate developmental toxicity assay using the frog Xenopus laevis can support student-initiated toxicology experiments that are relevant to humans. Teams of students formulate hypotheses, perform experiments, analyze data, and present their results. By performing experiments to investigate the toxicity of household chemicals, pharmaceuticals, or agricultural chemicals, students will gain an appreciation of the environmental effects of improper disposal of common chemicals and industrial or agricultural run-off.

The Work Of The Urban Commons: Limited-Equity Cooperatives In Washington, D.C., Amanda Huron

Dissertations, Theses, and Capstone Projects

This research theorizes the work of the urban commons through close examination of a group of ten limited-equity housing cooperatives in Washington, D.C. Limited-equity co-ops, or LECs, are a noncommodified resource that is collectively owned and maintained by their members. I argue that LECs are a manifestation of the commons, and that they represent a specific form of the commons - the urban commons. In this research, I ask: how does the urban commons - as manifested in this case by limited-equity housing cooperatives - function? The commons, as I theorize it, is a space that both provides a basis …

Facebook: Shifting Privacy, Identity, And Power Online, Rachel Verni

Dissertations, Theses, and Capstone Projects

Due to staggering technological shifts in recent decades, the Internet has become a routine fixture in everyday life. The popularity of social networking sites, in particular, raises myriad questions regarding identity construction and social interaction. It is also unclear how these practices are related to perceptions of privacy. This dissertation examines how traditional notions of privacy compare, and apply, to privacy on the Internet and considers how issues of power are (re)created in online spaces. By focusing on identity enactment strategies and social connectivity practices, this work sheds light on the ways in which individuals define privacy and choose to …

The Creeks, Beaches, And Bay Of The Jamaica Bay Estuary: The Importance Of Place In Cultivating Relationships To Nature, Kristen L. Van Hooreweghe

Dissertations, Theses, and Capstone Projects

It is often assumed that people living in urban areas lack connections to the natural world and are the source of environmental problems. This assumption, however, is an oversimplification of urban life. Employing an eco-ethnography, with participant observations, qualitative interviews, and an environmental history, this study examines New York City's Jamaica Bay estuary and surrounding neighborhoods to understand how residents cultivate their relationships to nature in a dense urban setting. Many residents near Jamaica Bay have developed a strong connection to place that is rooted in their regular, embodied experiences living, working, playing, and praying on the Jamaica Bay estuary. …

Reading Through Prayer: Lectio Divina And "Liturgical Reading" In Some Medieval Texts, Marie Schilling Grogan

Dissertations, Theses, and Capstone Projects

Prayer texts found in a variety of medieval genres merit more careful scrutiny from literary critical perspectives. Such attention to the verbal artifacts, prayers, that memorialize an activity of central importance in medieval culture, praying, deepens our understanding not only of the prayers and the works in which they are found, but also of the milieu that produced them. This study seeks to model such a critical turn by reading three particular works "through" the prayers that constitute, punctuate and frame them -- privileging the prayers as the starting points for the investigation of their literary and devotional settings. This …

Age Composition And Distribution Of Red Drum (Sciaenops Ocellatus) In Offshore Waters Of The North Central Gulf Of Mexico: An Evaluation Of A Stock Under A Federal Harvest Moratorium, Sean P. Powers, Crystal Hightower, J. Marcus Drymon, Matthew W. Johnson

University Faculty and Staff Publications

Because of a lack of fishery- dependent data, assessment of the recovery of fish stocks that undergo the most aggressive form of management, namely harvest moratoriums, remains a challenge. Large schools of red drum (Sclaenops ocellatus) were common along the northern Gulf of Mexico until the late 1980s when increased fishing effort quickly depleted the stock. After 24 years of harvest moratorium on red drum in federal waters, the stock is in need of reassessment; however, fishery dependent data are not available in federal waters and fishery-independent data are limited. We document the distribution, age composition, growth, and condition of …

Criminal, Antisocial, And Temporal Patterns In The Histories Of Serial And Non-Serial Sexual Murderers, Victoria Blair Mesa

Dissertations, Theses, and Capstone Projects

Despite its having been the subject of clinical and scholarly inquiry for more than two centuries, empirical research regarding the phenomenon of sexually-motivated homicide remains limited. In particular, relatively few prior studies have focused on perpetrators' criminal and antisocial backgrounds, and these often examine only the data found in official arrest and conviction records, which frequently provide incomplete accounts of offenders' histories. Even fewer researchers have investigated whether temporal patterns exist in the offense histories of sexual murderers. The current study included data on 46 serial and 93 non-serial perpetrators of sexually-motivated homicide, obtained from a large archive. Data collection …

On The Origins Of The Cute As A Dominant Aesthetic Category In Digital Culture, Dylan E. Wittkower

Philosophy Faculty Publications

In discussions of online culture, nobody has yet given sufficient consideration to the importance of cute animal pictures. While there are perhaps obvious reasons for this aspect of online culture being and remaining understudied, from an objective stance we should consider it both surprising and noteworthy that, once given the means of mass communications and internationally accessible publication, a primary activity that people are interested in and committed to is the sharing of cute and funny pictures, especially of cats. This presumably unforeseeable outcome is made stranger yet by the relative lack of commercial motivation for a communications category that …

Recollecting Turbulence: Catastrophe And Sacrifice In The "History Of My Life" By Henry Darger, Carl Watson

Dissertations, Theses, and Capstone Projects

This study of "The History of My Life" the 5,086 page autobiographical text by the outsider artist/author Henry Darger, uses non-linear modes of analysis, such as chaos and complexity theory, to explore the meaning of Darger's epic narrative. Beginning with the idea that turbulence, seemingly chaotic, actually comes about as a compensatory restructuring of inadequate or unstable system dynamics, this study goes on to show that, as both influence and effect, turbulence is found at every level of Darger's life and art, both in theme and structure. "My Life" is a prime example: an extended narrative describing a cataclysmic tornado, …

Watching The Hen House: Judicial Rulemaking And Judicial Review, Carrie Leonetti

Nebraska Law Review

The thesis of this Article is a simple one: Courts regularly engage in rulemaking of questionable constitutionality, then exercise the exclusive jurisdiction of judicial review to rule on constitutional challenges to the rules that they themselves have promulgated, obfuscating the appearance of impartiality and accountability and preventing the unsophisticated from realizing that a benefit has been conferred on a more sophisticated faction. Although this Article focuses on the concerns arising from judicial review of judicial rulemaking, it includes some observations as to why, as a matter of policy, expansive judicial rulemaking authority itself is concerning. It, therefore, joins the extensive …

Identification Of 23 Specific Nucleotide Patterns In The Hn Gene Of Newcastle Disease Viruses Isolated From Iran, Majid Esmaelizad, Mehdi P. Ashtiani, Saber Jelokhani Niaraki, Khadije Hashemnejad

Turkish Journal of Biology

Newcastle disease is considered the most contagious poultry disease and may cause severe economic loss in the poultry industry. The present study was undertaken to focus on molecular and phylogenetic analyses of the hemagglutinin-neuraminidase (HN) gene in the Iranian isolates. The nucleotide sequence of the HN (780-903 nt) coding region of 6 Newcastle disease viruses (NDVs), isolated from various outbreaks in Iran, was determined and aligned with previously published sequences of 26 NDV isolates in GenBank; the resulting alignment was then analyzed in terms of genetic variation. The number of nucleotide sequence variations presented by each of the isolates indicated …

Properties Of Biological Activity Of Ten Wild Almond (Prunus Amygdalus L.) Species, Ali Jahanban Esfahlan, Rashid Jamei

Turkish Journal of Biology

To compare the antioxidant and antiradical activity of phenolic extracts of different species of wild almond kernels (including the brown skin), 10 wild almond species were selected from Shahindezh and Qasemloo Valley in West Azarbaijan Province, Iran. The fruits of these almonds were collected, their kernels were separated from their hulls and shells and then ground, and methanolic extracts were prepared from the kernels. The total phenolic and flavonoid contents were determined using the Folin-Ciocalteu method and a colorimetric method, respectively. The extracts were also evaluated on their reducing power and their capacity to scavenge for DPPH radicals. Significant differences …

Genetic Diversity Of Natural Cyclamen Alpinum Populations, Belgi̇n Göçmen Taşkin, Ni̇lden Vardareli̇, Ersi̇n Doğaç, Ramazan Mammadov, Vatan Taşkin

Turkish Journal of Biology

The focus of this study was Cyclamen alpinum (formerly C. trochopteranthum). Habitat fragmentation, environmental degradation, and overharvesting of tubers have exerted pressure on native populations of this valuable ornamental species. Although the entire Cyclamen genus is in the Convention on International Trade in Endangered Species of Wild Fauna and Flora-Appendix II (CITES II), no species has yet been red-listed. Estimating the level and distribution of genetic variation in populations of rare and endemic species is important for conserving genetic diversity within a species in the context of well-developed conservation strategies. Currently, DNA markers are the most effective means used to …

Colonization Of Mycobacterium Phlei In The Rhizosphere Of Wheat Grown Under Saline Conditions, Dilfuza Egamberdieva

Turkish Journal of Biology

One of the natural reservoirs of potentially human-pathogenic bacteria is believed to be the rhizosphere. The aim of the present work was to test nontuberculous mycobacterium Mycobacterium phlei MbP18 for its ability to colonize the rhizosphere of wheat and to evaluate its effect on plant growth under saline conditions. In competitive wheat root tip colonization assays, M. phlei MbP18 showed poor competitive colonization of the wheat rhizosphere compared to the reference strain. The strain produced lipase, amylase, cellulase, and pectinase and grew well in the presence of high salt (up to 4% NaCl) and at high temperatures (up to 40 …

Biomarkers Of Petroleum Contamination In The Digestive Gland Of Perna Viridis (L.), Xivanand Narayan Verlecar, Karmabeer Jena, Somshekher Raghoba Desai, Priya Brata Das, Gagan Bihari Nityananda Chainy

Turkish Journal of Biology

Oxidative stress responses were evaluated in the digestive gland tissue of Perna viridis exposed to water-accommodated fractions (WAFs) of petrol and diesel at 0.5% and 5% concentrations over 5-, 10-, and 15-day periods. Increased lipid peroxidation, protein carbonyl, DNA integrity, and hydrogen peroxide in WAF-exposed specimens are indicative of oxidative damage due to dissolved petroleum extracts. A consistent increase in superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione-S-transferase, reduced glutathione, and ascorbic acid in WAF-exposed specimens signify the importance of antioxidants in protecting the cell against the oxidative damage arising from petroleum contamination. The responses of field specimens collected from …
