Mechanisms Of Dietary Protein-Induced Changes In Calcium Absorption Efficiency, Jessica D. Bihuniak

Doctoral Dissertations

We undertook a randomized, double-blind, crossover study in 14 healthy women who were required to ingest a 6-day low protein diet supplemented with CaSR-AAA (calcium-sensing receptor-activating amino acids), DAA (dibasic amino acids) or methylcellulose capsules (control). All subjects ingested all three diets in random order. Prior to each experimental diet subjects consumed an 11 day adjustment diet. Calcium absorption was measured on day 5 of each dietary intervention using dual-stable calcium isotopes. The clinical trial tested the hypothesis that dietary protein affects the efficiency of intestinal calcium absorption by activating the calcium sensing receptor (CaSR). Supplementation with CaSR-AAA did not …

Which Biomarkers Reveal Neonatal Sepsis?, Kun Wang, Vineet Bhandari, Sofya Chepustanova, Greg Huber, Stephen O′Hara, Corey S. O′Hern, Mark D. Shattuck, Michael Kirby

Publications and Research

We address the identification of optimal biomarkers for the rapid diagnosis of neonatal sepsis. We employ both canonical correlation analysis (CCA) and sparse support vector machine (SSVM) classifiers to select the best subset of biomarkers from a large hematological data set collected from infants with suspected sepsis from Yale-New Haven Hospital's Neonatal Intensive Care Unit (NICU). CCA is used to select sets of biomarkers of increasing size that are most highly correlated with infection. The effectiveness of these biomarkers is then validated by constructing a sparse support vector machine diagnostic classifier. We find that the following set of five biomarkers …

Don't Disturb The Consensus, Ishrat Husain Dr.

Faculty Research - Newspaper and Magazine Articles

Pakistani Prime Minister Nawaz Sharif and his Indian counterpart, Prime Minister Manmohan Singh, met in New York on the sidelines of the U.N. General Assembly meeting in September. While many hoped it would signal a fresh start in Indo-Pak relations, it proved to be a missed opportunity for the two countries to get their bilateral relations back on track. The much awaited resumption of composite dialogue was never announced.

News Source Preferences And News Source Credibility Among College Staff, Faculty, And Students, Larissa A. Bolalek

News consumption practices in the United States have been studied for decades. Recent technology has influenced traditional news consumption by allowing people to access news through the Internet and social media. Today, people have more options than ever as to where to obtain news. People remain interested in getting news that is credible and trustworthy. A survey was distributed to in order to learn where people say they turn for their primary sources of news and the credibility people assigned to various news sources. Respondents were split up into two groups, heavy and light social media users. Results suggest that …

A Content Analysis Of Advertisements In The Fra And Craftsman Magazines, 1908-1916, Kathryn Runyan

Theses

The present study used content analysis to examine advertisements appearing in Elbert Hubbard's The Fra and Gustav Stickley's The Craftsman magazines from 1908 through 1916. A total of 599 ads were analyzed to determine what type of advertisements dominated this period and to discover differences in the persuasive and informative appeals used by two creative forces in American business at the beginning of the 20th century, Elbert Hubbard and Gustav Stickley. The purpose of this study is to understand the advertising strategies appearing in The Craftsman and The Fra magazines.

Battery Energy Storage Systems To Mitigate The Variability Of Photovoltaic Power Generation, Heath Alan Gurganus

Dissertations and Theses

Methods of generating renewable energy such as through solar photovoltaic (PV) cells and wind turbines offer great promise in terms of a reduced carbon footprint and overall impact on the environment. However, these methods also share the attribute of being highly stochastic, meaning they are variable in such a way that is difficult to forecast with sufficient accuracy. While solar power currently constitutes a small amount of generating potential in most regions, the cost of photovoltaics continues to decline and a trend has emerged to build larger PV plants than was once feasible. This has brought the matter of increased …

Students With Blindness Explore Chemistry At ‘Camp Can Do’, Cary A. Supalo, H. David Wohlers, Jennifer R. Humphrey

Journal of Science Education for Students with Disabilities

Students with blindness or low vision are often discouraged from full participation in laboratory science classes due to the inadequacy of current methodological approaches and the lack of sophisticated adaptive technologies. Consequently, these students rarely go on to pursue advanced studies and employment in the sciences. In response to his own frustrations as a scientist with blindness, Supalo conceived, co-founded, and managed the Independent Laboratory Access for the Blind (ILAB) project for his doctoral research in chemistry. Numerous multisensory tools, technologies, and methodologies for teaching the sciences to students with visual impairments were developed and evaluated by the ILAB team. …

Using An Inquiry-Based Teaching Approach To Improve Science Outcomes For Students With Disabilities: Snapshot And Longitudinal Data, Jonte Taylor, William J. Therrien, Erica Rochelle Kaldenberg, Sarah J. Watt, Niphon Chanlen, Brian Hand

Journal of Science Education for Students with Disabilities

Poor science achievement has been an educational issue for a number of years. Students with disabilities have traditionally fared worse. Research suggests that students with disabilities may respond better to instruction using an inquiry-based approach vs. traditional textbook instruction when measuring science achievement on standardized measures. The researchers report achievement data on the Iowa Test of Basic Skills from a target school district for students Individualized Education Program’s (IEP) and non-IEP students, as well as students with IEP’s at the state level. Using an argument-based inquiry approach to science instruction called the Science Writing Heuristic (SWH); the researchers report data …

Ambiguity And Inconsistencies In Mathematics Spoken In The Classroom: The Need For Teacher Training And Rules For Communication Of Mathematics, M.D. Isaacson, S. Srinivasan, Lyle Lloyd

Journal of Science Education for Students with Disabilities

Mathematics has the potential for being spoken ambiguously. This is problematic for many students, in particular those who have disabilities that inhibit processing of printed material. This paper documents the magnitude of potential ambiguity arising from textbooks and provides a measure of the degree to which potential ambiguity is actualized through teachers’ speech. Inconsistency among teachers in speaking mathematics is also documented. Evidence is provided that teachers are not adequately aware of ambiguity in speaking mathematics and that they believe that they should have training regarding ambiguity in communication of mathematics and how to speak mathematics non-ambiguously.

Operating A Very Large-Section, Hybrid Principles Of Marketing Class At A Public University: Lessons Learned Over Ten Years, Bruce Robertson, Kevin Kelly

Atlantic Marketing Journal

This case study describes the development and operation of a very large-section, hybrid Principles of Marketing Class. The authors describe the original structure of the class, major adaptations and decisions related to its development over time, and discuss four lessons learned through this process: (1) The non-traditional format needs a lot of explaining, (2) This will always be an experimental class, (3) Plan in advance and have contingency plans, (4) It is easier to share the work than it is to share the budget. They conclude by suggesting Principles of Marketing is a logical entry point for innovative technology.

Exploring Consumer Behavior Using Student Constructed Photographic Essays And Film Projects, Seth Ellis

Atlantic Marketing Journal

Millennials can be characterized by a preference for classroom discussion rather than lecture, working in small collaborative groups, and a desire for structure and steady feedback. This paper describes an undergraduate course, Visual Methods for Exploring Consumer Behavior, where students examine topics in consumer behavior by constructing photographic essays and films as primary research vehicles. We discuss how the course is operationalized, how to encourage and support students in their endeavors, and how to avoid some of the pitfalls we have encountered.

Engaging Students Through A Virtual Live Case, John M. Zych

Atlantic Marketing Journal

Students are motivated to engage in their education when they understand how mastery of course content will translate to practical skills needed in the job market. In marketing education, live cases often are used to help students make a clear connection between course content and its application to real-world business problems. There are times, however, when a live case is not feasible or available. For these circumstances, the author has developed an innovative approach which approximates a live case. The approach combines components of a live case with historical analysis to have students perform an in-depth market strategy analysis of …

The Collaborative Classroom: New Technology Brings New Paradigm, Ben Clapp, James Swenson

Today, technology is the agent of change that is revolutionizing education. The collaborative classroom, where teachers and students openly gather and share information to empower one another for the purpose of learning, is quickly replacing the existing reality of the traditional classroom where teachers lecture and provide their expertise.

Collaboration is a tool used in classrooms not only to engage students but also to bring them together and teach them how to work together. Peer review is an important collaborative technique that allows students to share their work and ideas for the purposes of improvement and shared learning. With the …

Quality Of Student Effort: Improving Through Achievement Mastery And Psychological Needs, Michael W. Pass

Atlantic Marketing Journal

Instructors shaping the classroom experience with a variety of innovative teaching methods may improve the quality of student effort. This study facilitates effective innovation by developing and testing a model that shows how the quality of student effort is influenced by an achievement mastery goal orientation in tandem with the student’s fulfillment of three psychological needs. Findings reveal the influence of these factors, thus highlighting their importance and suggesting that instructors give attention to each one of them when deciding to take steps to increase student effort. Achievement Goal Theory and Self-Determination Theory are drawn upon to advance hypotheses that …

Using Technology To Teach Pricing Concepts, Kathy Winsted, Judy Graham

Atlantic Marketing Journal

This paper identifies a useful technology tool that aids in the teaching of pricing strategies and allows students to experience the interactive effects of decisions involving pricing, production levels, and promotional spend. This innovative technology tool can be easily implemented either online or in the classroom. Concepts related to pricing strategy do not typically evoke enthusiasm from students, and in many cases, both students and professors would welcome an engaging, innovative way to teach the key concepts of pricing strategy. In the past, attempts to convey pricing concepts through experiential learning have involved large-scale simulations that extend throughout the length …

Principal Angles And Approximation For Quaternionic Projections [Dataset], Terry A. Loring

Math and Statistics Datasets

We extend Jordan's notion of principal angles to work for two subspaces of quaternionic space, and so have a method to analyze two orthogonal projections in the matrices over the real, complex or quaternionic field (or skew field). From this we derive an algorithm to turn almost commuting projections into commuting projections that minimizes the sum of the displacements of the two projections. We quickly prove what we need using the universal real C*-algebra generated by two projections.

The Effects Of Random Bottom Bathymetry On Coherence In Shallow Water Acoustic Propagation, Jennifer Leigh Wylie

Open Access Dissertations

In an ideal shallow water propagation channel the sound field is accurately described by normal modes and the mode structure is predictable with clean separated modes. However the real ocean environment is rarely ideal, and variations in bottom bathymetry and water column sound speed are usually present. Random fluctuations of the sound speed in time, space, and/or the boundaries can distort modes such that phase coherence is reduced and under some conditions completely lost. The basic research community seeks to understand the effects of internal waves on temporal coherence. Here the study method of choice is to use fixed system …

Reflectance And Ultrastructure Of The Retinal Nerve Fiber Layer In Normal And Glaucomatous Retinas, Ye Spector

Open Access Dissertations

Glaucomatous damage to the RNFL usually precedes detectable visual field loss; clinical assessment of RNFL optical properties has been valuable in diagnosis of glaucoma and other neuropathic diseases. In this dissertation, we aimed to improve the understanding of the changes of RNFL reflectance and its underlying ultrastructure under the development of glaucoma. We used simultaneous immunohistochemical labeling and both en face and in-depth confocal imaging to study axonal cytoskeletal alteration of F-actin, MTs and NFs across the retina in the context of glaucoma. We have found that alteration of each cytoskeletal components is different from each other, and different degree …

An Inverse Relationship Between Resistance To 2-Deoxy-D-Glucose And Glucose Starvation In Tumor Cells Under Normoxia, Katherine Beth Philips

Open Access Dissertations

A distinguishing feature of tumor cells is their upregulation of glucose metabolism. This metabolic change from oxidative phosphorylation to aerobic glycolysis creates a selective window that can be exploited for anticancer therapy. Here we investigate mechanisms by which pancreatic cancer cells respond to therapeutic (2-deoxy-D-glucose, 2-DG) and physiologic (glucose starvation, GS) forms of glucose restriction. 2-Deoxy-d-Glucose (2-DG) is a sugar analog of both glucose and mannose and thus has established activities inhibiting glycolysis and interfering with glycosylation, respectively. Due to 2-DG’s dual functions, it has classically been thought of as a glucose deprivation mimetic. Additionally, these roles render 2-DG an …

Openness And Closure In Modernist Cinema: Antonioni/Resnais/Haneke/Martel, Oscar Jubis

Open Access Dissertations

Narrative exposition evokes questions about characters and events. A narrative opens gaps when information necessary to interpret the plot has yet to be offered. Some questions perform what Barthes calls primary or “hinge” functions. Narratives revolve around these presiding questions or gaps while secondary questions serve complementary purposes. The opening of gaps and the timing of their closing are the means by which narratives incite our curiosity, foment our interest, and hold our attention. Most narratives aim to achieve resolution and grant a sense of closure by filling the gaps with sufficient certitude. A degree of ambiguity is present in …

Order Fitting Policies For Service Systems With Pricing And Inventory Decisions, Salvador Romo-Fragoso

Open Access Dissertations

The present work is the foundation for our line of research, looking for policy solutions for: order acceptance, capacity management with interruptions, pricing, and trade-offs between different assets. The first model represents an organization choosing order fitting and pricing policies for a service company selecting between deals and regular jobs with poisson arrivals. The prices for regular jobs are exogenous, whereas winning the deals depends on pricing bids. We derived and compared optimal pricing for two distinct order acceptance policies under a setting where the server had no queue. We investigated the impact of the system parameters on the optimal …

Art Imitating Life: How Heteronormative Values Shape And Encourage The Censorship Of Jamaican Dancehall Music, Aleia Walker

Open Access Theses

In 2009, increasingly violent and sexually explicit lyrics led the Broadcasting Commission of Jamaica to issue directives severely censoring the broadcasting of dancehall music on radio and television. Dancehall music, a descendant of reggae, serves as a cathartic release for the working-class in Jamaica with lyrics and dances that focus on achieving primal pleasures. Since entering mainstream society, dancehall has been unappreciated by those outside of its following. This thesis seeks to understand the purpose of the offensive lyrics and the subsequent need for censorship by combining various gender theories with the analysis of lyrics, media, government documents, historical contentions …
