Modeling Of Yeast Pheromone Pathway Using Petri Nets, Abhishek Majumdar

School of Computing: Dissertations, Theses, and Student Research

Yeast (Saccharomyces cerevisiae) is one of the most widely studied single celled organisms. Mating of yeast cells occur between cells of opposite mating types a and alpha. Pheromone secretion by a cell alerts the corresponding opposite type cell about its presence and eventually facilitates the process of mating between them. The details of how pheromones affect cells can be studied from the pheromone response pathway in a yeast cell. A response pathway typically depicts the chain of interactions that happens between the different proteins in the cells in response to the pheromone. In this thesis we model the …

The Acoustic Qualities Of Embera Katío Stops, Gisella Teresa Greenfield Vélez

Theses and Dissertations

Embera Katío is a Chocó language of Colombia. This thesis presents the results of an acoustic analysis of the stops as produced by speakers from the departments of Córdoba and Antioquia. The analysis of the stops allows me to establish more conclusively their actual physical correlates and corresponding phonological categories.

Five male adult native speakers of Embera Katío were recorded on location. Each one pronounced sixty-one words in a constant sentential frame, five times each. The utterances were analyzed acoustically, measuring duration, formant onset time, pre-voicing, and burst.

Analysis of the data verifies that Embera Katío has three series of …

Density And Diversity Of Penaeid Shrimp And Fish Species In Near-Shore Seagrass Beds Of Northern Biscayne Bay, Florida (Usa), Robin Cascioli

HCNSO Student Theses and Dissertations

Seagrass beds serve critical functions in coastal Florida ecosystems. The beds serve as nursery habitat for many juvenile reef fish species and provide protection for many types of benthic organisms found in Biscayne Bay. They help stabilize sediment that would otherwise increase turbidity around coral reefs, filter the water of contaminants, and help support an entire food web. Three species of seagrass were found at the study sites in northern Biscayne Bay: Thalassia testudinum, Halodule wrightii, and Syringodium filiforme. This study focused on understanding the organism habitat interaction by determining the species diversity, seasonal densities, and the …

Why Snails? How Gastropods Improve Our Understanding Of Ecological Disturbance, Christopher P. Bloch

Bridgewater Review

The concept of equilibrium - the idea that a perturbed system will tend to return to its original state - is the basis for many foundational theories in ecology. Yet, the spatial and temporal dynamics of ecosystems are strongly influenced by disturbance. If a particular disturbance greatly alters local climatic conditions, gastropods should be among the first organisms to show a measurable response. The effects of human alteration of habitats (for example, conversion of forest to agriculture) have much longer-lasting effects than those of natural disturbances.

Urban Trail System Planning In The Western United States: An Analysis Of The Trail-Specific Planning Efforts Of Four Cities That Have Implemented Urban Trail Systems, Kenneth C. Richley

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

States in the Western United States are growing at rates outpacing the rest of the nation. This growth is placing pressure on communities to develop their current open space for residential or commercial use. As cities develop a comprehensive open space plans, several elements arise. One critical element is connectivity. This connectivity is most often realized in the form of greenways. In many cities these greenways contain urban trail systems that provide significant recreation and connectivity benefits.

This thesis investigates the current recommended models used to plan for greenway, synthesizes them into a recommended model process, and analyzes case studies …

Effects Of Choice Of Reinforcement On The On-­Task Behavior Of Kindergarten Students With Developmental Delays, Karen Binette

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A high degree of external control is maintained in classrooms serving students with behavioral and developmental disabilities. However, decision making is an important developmental objective related to personal control and dignity. Choice making and discriminating preferred over less preferred outcomes is an important skill that is seldom taught to students with developmental disabilities. Previous research includes studies conducted in clinical settings or with populations with severe disabilities.

The Expressive Cost Of Corporate Immunity, Gregory M. Gilchrist

UC Law Journal

Is it possible to justify imposing criminal liability on corporations? Two basic aspects of criminal law have no application to corporations: Corporations cannot be jailed and they cannot form mental states. Moreover, there is reason to think that much of the deterrent effect generated by corporate criminal liability could be generated more efficiently by civil liability. Still, the demand for criminal prosecution of corporations remains high. This Article seeks to understand why we have corporate criminal liability, and it concludes that expressivism is necessary to justify the practice. Expressivism justifies punishment by reference to the benefits of a statement of …

Understanding And Incentivizing Biosimilars, Jason Kanter, Robin Feldman

UC Law Journal

Congress recently passed the Biosimilars Act in an attempt to replicate the success that generic small molecule drugs have enjoyed under the Hatch-Waxman Act. The Biosimilars Act provides a pathway for biosimilars to achieve quicker and less expensive FDA approval than what is required for a new biopharmaceutical. There is, however, greater uncertainty and cost associated with achieving the coveted biosimilarity status. This reflects the complex production methods of biopharmaceuticals, along with the many factors that can alter the structure and function of such drugs. This Article analyzes the Biosimilars Act and the draft guidances recently released by the FDA. …

Design And Implementation Of A Genre Hybrid Video Game That Integrates The Curriculum Of An Introductory Programming Course, Cory Buckley

All Theses

Video games have a history of being exploited for education. However, all too fre- quently, the resulting educational video game is either transparent in its hijacking of video game media, or the educational content is not intelligently placed within the context of the game. In this paper we analyze existing educational video games and observe popular commercial video game mechanics to form a more player oriented development mindset. Our approach involves mingling game mechanics that are not commonly used together to create a genre hybrid educational video game with a seamlessly integrated introductory programming curriculum. We use a machine architecture …

Ghost Tiger Beetle (Cicindela Lepida): Species Conservation Assessment, Melissa J. Panella

Nebraska Game and Parks Commission: Publications

The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the ghost tiger beetle, a.k.a. white tiger beetle, (Cicindela lepida) as a Tier I at-risk species of high conservation priority. Some general management recommendations are made here regarding ghost tiger beetles; however, conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge …

Powell, Nathan Cooper, Mahdi Abdelguerfi, Eileen E. Hofmann, Janak Dahal, Shengru Tu, John Finigan, Benjamin S. Eberline, Jerome F.La Peyre, Megan K.La Peyre, Fareed Qaddoura

Faculty Publications

A numerical model is presented that defines a sustainability criterion as no net loss of shell, and calculates a sustainable harvest of seed (<75 >mm) and sack or market oysters (≥75 mm). Stock assessments of the Primary State Seed Grounds conducted east of the Mississippi from 2009 to 2011 show a general trend toward decreasing abundance of sack and seed oysters. Retrospective simulations provide estimates of annual sustainable harvests. Comparisons of simulated sustainable harvests with actual harvests show a trend toward unsustainable harvests toward the end of the time series. Stock assessments combined with shell-neutral models can be used to …

Assessing The Impacts Of Dams On Nutrient And Sediment Loading In The Kalamazoo River Using The Soil And Water Assessment Tool (Swat), Daniel Henry Serfas

Masters Theses

The Soil and Water Assessment Tool (SWAT) was applied to the Kalamazoo River Watershed in order to evaluate the impacts that several dams within a superfund site "Area of Concern" have on the sediment, nutrients, and streamflow of the system. It was hypothesized that the SWAT model could be used to recreate the watershed in hopes of estimating the amounts of nitrogen, phosphorus, and sediment that would result from the removal of the dams. The model would then be used to evaluate dam removal scenarios to come up with a best management practice (BMP).

The model was calibrated, however, during …

Assessment Of The Discriminative Stimulus Effects And Time Courses Of Salvinorin A And Two Synthetic Salvinorin B Derivatives, Methoxylmethyl (Mom) And Ethoxymethyl (Eom), Ethers In Rats Trained To Discriminate U69,593, Lisa M. Bell

Masters Theses

Research regarding the psychopharmacology of salvinorin A, the main psychoactive ingredient in the hallucinogenic plant Salvia divinorum, has been motivated largely by a recent increase in its recreational use and widespread media attention focused on this plant and its extracts. In addition, there is considerable evidence that drugs acting on kappa opioid receptors (KOR) may have therapeutic potential in the treatment of some neuropsychiatric conditions, including drug dependence and mood disorders. Although the neuropharmacological actions of salvinorin A are well established, only a few studies have explored the behavioral effects of this substance in comparison to the KOR agonist, …

How Now Shall We Consume: Widening Conception Of Political Consumption And Analysis Of The American Buyer, John Patton Chew

Masters Theses

As consumption of goods has risen, it has increasingly become a space for political activists to brand products and for the everyday consumer to voice their opinion on how businesses should be run. Through the practices of buycotting and boycotting political consumers have increasingly been able to show their support for issues as diverse as gay rights, environmental issues, funding for disease cures, and American based products.

This study attempts to gain an understanding of how prevalent political consumption is and of who are political consumers. The findings show that a large percentage of the population is knowledgeable and active …

The Rise And Fall Of Kin Structure In The Neotropical, Family-Living Buff-Breasted Wren (Cantorchilus Leucotis) In Gamboa, Panama, Sarah C. Alessi

Masters Theses

Family-living species provide an exciting model to examine how natal dispersal and kin structure influence genetic structuring within local populations. Juvenile buff-breasted wrens (Cantorchilus leucotis) of both sexes delay dispersal and exhibit short-distance natal dispersal, which should lead to kin-structured populations in which relatives of both sexes occupy neighboring territories. Blood samples collected from juvenile and adult wrens in Gamboa, Panama were analyzed using microsatellite markers to determine whether related individuals are spatially clustered on neighboring territories, spatial clusters of relatives change over time, and if kin structure is sex-specific. Global and local spatial autocorrelation analyses detected genetic …

Laboratory Measures Of Aggression In Methadone Patients, Catherine M. Gayman

Masters Theses

Research suggests that current heroin users and individuals with a prior history of heroin dependence tend to be more aggressive than nonusers. No study has yet investigated whether opioid withdrawal affects aggressive responses on a laboratory task. The present study investigates whether mild opioid withdrawal affects aggression in six males and six females (N=12) undergoing methadone maintenance therapy. Aggressive behavior is measured using the Point Subtraction Aggression Paradigm (Cherek, 1981) computer task. Participants press buttons to earn money towards gift certificates. Money subtractions occur periodically and these are attributed to the behavior of a partner who is actually fictitious. Participants …

Early Arrest Mutant Ogre: A Defect In Cytokineis Caused By A Mutation In The Gene Racgap1, April Wicklund

Masters Theses

The early arrest mutant ogre, isolated in the Tübingen screen, has a block in cytokinesis (Kane et al., 1996). Here I use genetic and molecular techniques to demonstrate that the ogre phenotype is caused by a lesion in the gene encoding Racgap1. I performed fine mapping studies using microsatellite markers to a 0.15 cM region containing the ogre locus. DNA sequence data revealed a nonsense mutation in the Racgap1 gene of ogre mutants, and in situ hybridization experiments showed a loss of racgap1 mRNA at later stages of development, likely by nonsense mediated decay. This evidence supports the abolishment …

Subsistence In The Shrinking Forest: Native And Euro-American Practice In 19th-Century Connecticut, William A. Farley

Graduate Masters Theses

Southeastern Connecticut in the 19th century represented a setting in which Native Americans living on reservations were residing in close proximity to Euro-American communities. The Mashantucket Pequot, an indigenous group who in the 19th century resided on a state-overseen reservation, and their Euro-American neighbors both utilized local and regional resources in order to achieve their subsistence goals. This thesis seeks to explore the differences and similarities of the subsistence practices employed by these two groups. It further seeks to examine the centrality of forest landscapes to both Mashantucket and Euro-American subsistence, and to interpret the importance of the reservation to …
