The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin Jan 2014

The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin

Honors Theses

The global fisheries crisis has led to an increasing recognition for the need to relieve pressure on overfished, popular food fish stocks. Opportunities exist to shift consumer demand toward more sustainable choices, including fish that may be locally abundant. Attempts have been made to market underused fish (sometimes termed “trash fish”) that represent more sustainable alternatives; however, it is unclear whether consumers will choose to purchase these more sustainable options, particularly if underused fish are also unfamiliar. Chapter 1 reviews existing research and current issues surrounding sustainable seafood and the recent shift toward local, abundant, undervalued species in New England’s …

The Relationships Between Local Food And Food Security In Maine, Erin Love Jan 2014

The Relationships Between Local Food And Food Security In Maine, Erin Love

Honors Theses

There is a food systems paradox in Maine: the State has one of the highest levels of food insecurity in the nation, while simultaneously experiencing a local agriculture boom. Maine has some of the largest percentages of young farmers and women farmers in the country and is home to the second highest number of artisan cheese makers of any state in the country. Amidst this exciting, sometimes quirky, agricultural activity there is a critical need for food systems development in the state, especially in the context of serving vulnerable populations. This thesis explores the ways in which Mainers are working …

The Effect Of Azo Textile Dyes On Gross Primary Production And Community Respiration In An Artificial Environment, Theresa L. Petzoldt Jan 2014

The Effect Of Azo Textile Dyes On Gross Primary Production And Community Respiration In An Artificial Environment, Theresa L. Petzoldt

Honors Theses

Azo dyes are the largest category of textile dyes in production today, with over 100,000 tons of dye produced yearly in the United States. Ten to fifty percent of this dye is not fixed to the fabric during the textile production process, and is therefore discarded as effluent. Because dye waste is difficult to process in wastewater treatment facilities, it is important to understand how this waste affects aquatic systems using a whole ecosystem approach. This study used an artificial stream to model the effects of four azo dyes on benthic biofilm production and respiration. Dyes were found to have …

The Impact Of Dams On Nitrogen Cycling In The Messalonskee Stream, Rebecca K. Forgrave Jan 2014

The Impact Of Dams On Nitrogen Cycling In The Messalonskee Stream, Rebecca K. Forgrave

Honors Theses

The Messalonskee Stream in central Maine has five hydroelectric dams on 16.6km. Each dam drastically changes the flow regime of the stream, dividing it into segments with different patterns of sediment settling and organic matter retention. I investigated how these disruptions impact nitrogen cycling, specifically nitrification rates above and below each dam. I expected higher nitrification rates above the dams, where levels of organic matter are higher, and lower rates below the dam where scouring removes organic matter and fine sediment from the streambed. I measured sediment nitrification rates with a nitrapyrin-inhibition assay and potential drivers of nitrification including sediment …

The Talbot Effect, Malia Kawamura Jan 2014

The Talbot Effect, Malia Kawamura

Honors Theses

The goal of this project is to experimentally investigate the optical Talbot effect and the electron Talbot effect. The Talbot effect is a near-field diffraction effect which occurs when plane waves are incident upon a grating. The Talbot effect creates full grating revivals at integral Talbot lengths and revivals with greater spatial periodicity at fractional Talbot lengths. We use a green helium neon laser and Ronchi rulings to take CCD camera images of the fractional Talbot revivals directly. Additionally, a photodiode records light intensity as a function of time as a second identical grating is moved to verify the presence …

Minus 25 Betty Tyson, Taunja Isaac Jan 2014

Minus 25 Betty Tyson, Taunja Isaac

Theses

Betty Tyson was convicted of murder in May 1973 in Rochester, NY. She was sentenced to 25 years to life in prison. Her trial was hasty and the jury of peers she faced was all white. The evidence against her was tainted yet she was still found guilty. I was 9 years old when I first heard this story. When I decided to pursue my Master in Fine Art, I remembered this story and wanted to use my journalism instincts that I developed during my undergraduate degree at SUNY Brockport. I approached my thesis committee for approval to pursue this …

Using Measures Of Risk Perception To Predict Information Security Behavior: Insights From Electroencephalography (Eeg), Anthony Vance, Bonnie Anderson, C. Brock Kirwan, David Eargle Jan 2014

Using Measures Of Risk Perception To Predict Information Security Behavior: Insights From Electroencephalography (Eeg), Anthony Vance, Bonnie Anderson, C. Brock Kirwan, David Eargle

Faculty Publications

Users' perceptions of risks have important implications for information security, as the actions of individual users can compromise entire systems. Therefore, there is a critical need to understand how users perceive and respond to information security risks. Previous research on perceptions of information security risk has chiefly relied on self-reported measures. Although these studies are valuable, risk perceptions are often associated with feelings—such as fear or doubt—that are difficult to measure accurately using survey instruments. Additionally, it is unclear how these self-reported measures map to actual security behavior. This paper contributes by demonstrating that risk-taking behavior is effectively predicted using …

Time Efficiency, Written Feedback, And Student Achievement In Inquiry-Oriented Biology Labs, John M. Basey, Anastasia P. Maines, Clinton D. Francis

International Journal for the Scholarship of Teaching & Learning

We examined how different styles of written feedback by graduate-student teaching assistants (GTAs) in college intro biology lab (USA) influenced student achievement and related the different styles to time efficiency. We quantified GTA feedback on formative lab reports and student achievement on two different types of assessments, a quiz in 2010 and a summative lab report in 2011. We evaluated the extent to which three categories of written feedback impacted student achievement (grade discrepancy between actual and ideal, short direct comments, and in-depth explanatory comments). Student achievement was best explained by both grade discrepancy and short direct comments in 2010 …

Investigating Transnational Collaboration Of Faculty Development And Learning: An Argument For Making Learning Culturally Relevant, Dr. Janine F. Allen

International Journal for the Scholarship of Teaching & Learning

Professional development offered to higher education faculty is meant to enhance pedagogy and improve practice. Inspired by a transnational partnership in Southeast Asia, this study aimed to discover how teacher education faculty perceived faculty development offered to them by university partnership colleagues from the United States. Survey findings indicate that certain faculty development strategies improved teaching and assessment practices and enhanced self-reflection. However, evidence also showed some negative faculty perceptions in relation to the US partner’s methodologies, and qualitative responses indicated a lack of relevancy to the Southeastern Asia context. Furthermore, negative correlations were found between faculty development workshops and …

An Unexpected Particle Oscillation For Electrophoresis In Viscoelastic Fluids Through A Microchannel Constriction, Xinyu Lu, Saurin Patel, Meng Zhang, Sang Woo Joo, Shizhi Qian, Amod Ogale, Xiangchun Xuan

Mechanical & Aerospace Engineering Faculty Publications

Electrophoresis plays an important role in many applications, which, however, has so far been extensively studied in Newtonian fluids only. This work presents the first experimental investigation of particle electrophoresis in viscoelastic polyethylene oxide (PEO) solutions through a microchannel constriction under pure DC electric fields. An oscillatory particle motion is observed in the constriction region, which is distinctly different from the particle behavior in a polymer-free Newtonian fluid. This stream-wise particle oscillation continues until a sufficient number of particles form a chain to pass through the constriction completely. It is speculated that such an unexpected particle oscillating phenomenon is a …

Optimization Of Orius Majusculus Release: Photoperiodic Sensitivity At Different Temperatures And Storage Of Diapausing Adults, Şeri̇fe Ünal Bahşi̇, İrfan Tunç

Turkish Journal of Agriculture and Forestry

The photoperiodic sensitivity and storage of Orius majusculus (Reuter) from Antalya was investigated to obtain data for the optimization of its release. In the current study, it was not possible to induce a high (up to 100%) incidence of diapause unless all the nymphal instars and adults were successively exposed (i.e. full exposure) to a short day length (11.5 h) at constant temperatures of 18 and 26 °C, and fluctuating temperatures of 10/26 °C. Hence an intermittent exposure to long day lengths, even for short periods of time (only during instars IV–V or adult stage), would avoid a high incidence …

Do Artificial Riffles Enhance Nutrient Retention In Restored Streams?, Adam Thomas Hughes Jan 2014

Do Artificial Riffles Enhance Nutrient Retention In Restored Streams?, Adam Thomas Hughes

Masters Theses

Kickapoo Creek, a tributary of the Embarrass River in Central Illinois, has undergone a stream restoration that included the construction of two artificial riffles. These structures were designed to slow flood waters, increase channel and substrate stability, and increase habitat heterogeneity in a stream impacted by erosion and sediment deposition. They may also provide stable substrates that affect the algal community, leading to shifts in algal community composition, increases in the biomass of primary producers, and subsequent increases in nutrient retention. I explored the effects of the restoration on instream nutrient retention by measuring and comparing phosphate uptake lengths, velocities, …
