A Comparison On The Classification Of Short-Text Documents Using Latent Dirichlet Allocation And Formal Concept Analysis, Noel Rogers, Luca Longo

Books/Book Chapters

With the increasing amounts of textual data being collected online, automated text classification techniques are becoming increasingly important. However, a lot of this data is in the form of short-text with just a handful of terms per document (e.g. Text messages, tweets or Facebook posts). This data is generally too sparse and noisy to obtain satisfactory classification. Two techniques which aim to alleviate this problem are Latent Dirichlet Allocation (LDA) and Formal Concept Analysis (FCA). Both techniques have been shown to improve the performance of short-text classification by reducing the sparsity of the input data. The relative performance of classifiers …

Redefining The Performance Degree Curriculum For The Crossover Saxophonist, Ian M. Cruz

Theses and Dissertations--Music

Many collegiate saxophone performance degree programs are overwhelmingly classical, adopting from other performance programs in the Western music tradition. However, there is a growing number of saxophone compositions that are “crossover” in nature. Crossover is a term used to describe the fusion of popular music styles in a classical setting. There is also evidence that collegiate music education as a whole is moving towards a more diverse curriculum, which emphasizes ethnomusicology. Due to this trend in composition and education, it is becoming increasingly important that saxophonists have the training of both classical and jazz disciplines.

The problem is that while …

Executive Functions And Word Reading Fluency: A Brief Intervention With Economically Disadvantaged Secondary Students, Vanessa Kim

PCOM Psychology Dissertations

This study evaluated the use of a brief intervention that was designed to assist economically disadvantaged secondary students increase their capacity for attention to orthography and increase their ability to shift between rapid sight word recognition and decoding of unknown words in order to improve their word reading accuracy and fluency. The participants (N = 14) were eighth and ninth grade students enrolled in an urban public high school and receiving special education services. The study used analysis of variance for repeated measures and paired measures t-tests to analyze pre- and post-test data. The results indicated significant findings (p < 0.5) in the students’ improvements in their sight word reading fluency and their ability to inhibit impulses and shift cognitive sets with accuracy and speed following the 8-week reading intervention. The findings suggest that exposure to repeated word fluency drills that target attention to orthography and shifting from sight word recognition to decoding may have influenced the students’ self-monitoring skills and offer further support regarding the hypothesized role of executive functions in the act of reading.

The Polycentric Turn: A Case Study Of Kenya's Evolving Legal Regime For Irrigation Waters, Daniel H. Cole, Stefan Carpenter, Elizabeth Baldwin

Articles by Maurer Faculty

Formal legal systems comprise a major part, but not the only part, of the “rules of the game” that structure social and social-ecological interactions. Throughout the twentieth century, centralization and consolidation of legal authority were dominant themes among many, if not all, legal systems. That process may have been successful in some cases, but in others the presumed economies of scale from consolidation and centralization either did not materialize or were offset by other social costs, including the failure to accommodate local knowledge, expertise, and preferences. In what could become a theme of the twenty-first century, many countries, including developing …

A Theoretical Framework For Evaluating Debtor-In-Possession Financing, Sandeep Dahiya, Korok Ray

Emory Bankruptcy Developments Journal

This excellent Article by business school professors Sandeep Dahiya and Korok Ray provides a mathematical framework as an analytical tool to assist bankruptcy judges when confronting a Debtor-in-Possession financing situation. The U.S. Bankruptcy Code provides enhanced priority and security features to debtor-in-possession (DIP) loans which can be obtained from a lender with whom the borrower may have no past lending relationship. The enhanced priority of DIP financing, and the choice of a DIP lender, significantly affect the investment decisions made by the firm. This Article shows that DIP loans from an existing lender leads to a higher level of investment. …

The Effects Of Thermal Stress On Fluorescent Protein Expression In An Indo-Pacific Scleractinian Coral Species, Acropora Tenuis, Anna Knochel

Independent Study Project (ISP) Collection

The scleractinian coral species that so heavily define tropical coral reefs are increasingly threatened by anthropogenic global warming. Rising sea surface temperatures in combination with light stress causes the photosynthetic breakdown of the coral’s algal symbiont, Symbiodinium. Corals have developed a number of physiological responses to handle acute stressors, such as the production of ultraviolet-protecting amino acids, heat shock proteins, the ability to shift symbionts, and the production of fluorescent proteins. The latter has been thought to play a photoprotective role in the coral holobiont, and studies have shown evidence that corals orient these pigments to divert harmful light away …

Characterization Of Insulin Sensitivity And The Plasma Lipidome In Periparturient Dairy Cows, Sina Saed Samii

Graduate Theses, Dissertations, and Problem Reports (ETD)

During the transition from gestation to lactation, dairy cows experience negative energy balance due to an increased demand for energy to support milk production coupled with inadequate energy intake. Energy deficit during the peripartum is associated with the development of insulin resistance which contributes to adipose tissue lipolysis. In turn, elevated free fatty acids (FFA) in circulation increase triacylglycerol (TAG) deposition in liver. This metabolic impairment is known to cause postpartum metabolic diseases including fatty liver and ketosis. Consequently, postpartum metabolic disease can lead to reduced milk production in early lactation, impaired reproductive performance, and increased culling rates. Moreover, cows …

Adapting Roof Support Methods For Anchoring Satellites On Asteroids, Grant B. Speer

Graduate Theses, Dissertations, and Problem Reports (ETD)

The use of anchorage in satellite and spacecraft design has been largely restricted to harpoon-inspired technology based on anticipated low strengths of cometary and asteroid material. Initial results from the Rosetta mission to comet 67P/Churyumov- Gerasimenko, however, have demonstrated both larger-than-expected compressive strengths of cometary materials and the importance of adequate anchorage to mitigate the risk of mission failure. The field of rock mechanics can provide unique insight into the design of these satellite and lander anchors by drawing on existing roof bolt technology. This study compared the behavior of tensioned point anchor and untensioned fully-grouted roof bolts with a …
