Leadership Education And Development In Stem High Schools, Andrea Stuiber, Katie Berger

Staff Publications & Research

Leadership. Education. Development. How are we inspiring young adults to grow as good and ethical leaders? Leadership should not be defined by a title or label. It’s about developing the perspective, skills and personal style of the whole individual. Through the LEAD program at IMSA, we believe that leadership can be learned through discussion and application. Thus, we have designed a year long course that takes an intricate look at various definitions, theories, models, and conceptualizations of leadership. Students are challenged to think critically about leadership during peer-to-peer facilitated class discussions, hands-on exercises, and group work.

Aiming For Success: Evaluating Statistical And Machine Learning Methods To Predict High School Student Performance And Improve Early Warning Systems, David Alexandro

Doctoral Dissertations

In response to the high school dropout crisis, which comes with great economic and social costs, early warning systems (EWSs) have been developed to systematically predict and improve student outcomes. The purpose of this study is to evaluate different statistical and machine learning methods to predict high school student performance and improve EWSs. By improving education EWSs, this study aims to better identify those students in need of targeted support and inform on-the-ground practitioners who may intervene long before students may be dropping out.

The current study explores the aforementioned methods in the context of a cohort of 40,008 Connecticut …

Divisibility In The Stone-Cech Compactification Of N, Salahddeen Khalifa

Dissertations

Let S a discrete semigroup. The associative operation on S extends naturally to an associative operation on βS,the Stone Cech compactification of S. This involves both topology and algebra and leads us to think how to extend properties and operations that are defined on S to βS. A good application of this is the extension of relations and divisibility operations that are defined on the discrete semigroup of natural numbers (N,.) with multiplication as operation to relations and divisibility operations that are defined on (βN,?) where (?) is the extension of the operation (.). In this research I studied extending …

Global Asymptotic Stability And Naimark-Sacker Bifurcation Of Certain Mix Monotone Difference Equation, Mustafa R. S. Kulenović, S. Moranjkić, M. Nurkanović, Z. Nurkanović

Mathematics Faculty Publications

We investigate the global asymptotic stability of the following second order rational difference equation of the form x_n+1= (Bx_nx_n-1+cx²_n-1),n =0,1,..., where the parameters B, F, b, and c and initial conditions x_-1 and x₀ are positive real numbers. The map associated with this equation is always decreasing in the second variable and can be either increasing or decreasing in the first variable depending on the parametric space. In some cases, we prove that local asymptotic stability of the unique equilibrium point implies global asymptotic stability. Also, …

University of Dayton doctoral student Ming Gong '15 is more comfortable at the keyboard of a computer or piano than trekking across snow and ice in sub-freezing temperatures. But, during May and June, she spent 10 days at a field summer school in Utqiagvik, Alaska, where she learned how to collect physical data in the Arctic.

Embryonic Origin And Genetic Basis Of Cave Associated Phenotypes In The Isopod Crustacean Asellus Aquaticus., Hafasa Mojaddidi, Franco Fernandez, Priscilla A. Erickson, Meredith E. Protas

Natural Sciences and Mathematics | Faculty Scholarship

Characteristics common to animals living in subterranean environments include the reduction or absence of eyes, lessened pigmentation and enhanced sensory systems. How these characteristics have evolved is poorly understood for the majority of cave dwelling species. In order to understand the evolution of these changes, this study uses an invertebrate model system, the freshwater isopod crustacean, Asellus aquaticus, to examine whether adult differences between cave and surface dwelling individuals first appear during embryonic development. We hypothesized that antennal elaboration, as well as eye reduction and pigment loss, would be apparent during embryonic development. We found that differences in pigmentation, eye …

Variation In Regional And Landscape Effects On Occupancy Of Temperate Bats In The Southeastern U.S.., Benjamin D. Neece, Susan C. Loeb, David S. Jachowski

KIP Articles

Habitat loss, wind energy development, and the disease white-nose syndrome are major threats contributing to declines in bat populations in North America. In the southeastern US in particular, the recent arrival of white-nose syndrome and changes in landscape composition and configuration have driven shifts in bat species populations and distributions. Effective management strategies which address these large-scale, community-level threats require landscape-scale analyses. Our objective was to model the relationship between ecoregional and landscape factors and occupancy by all bat species in South Carolina, USA, during summer. We conducted acoustic surveys from mid-May through July 2015 and 2016 and evaluated temporally …

An Analysis Of African-American Faculty Experiences During The Tenure Process, Katrina M. Hubbard

Dissertations

Abstract

How faculty allocate their time among research, teaching, and service, and the perceived quality of that work determines whether faculty obtain tenure or are released from the university (Bellas & Toutkoushian, 1999; Link, Swann, & Bozeman, 2008; Price & Cotten, 2006). Prior research indicated that African-American faculty comprised 4.5% of the faculty at high-activity research institutions and 3.5% of faculty at very-high-activity research institutions (The Chronicle of Higher Education Almanac 2016-2017, 2016).

The purpose of this study was to 1) document African-American faculty experiences during their tenure probationary period at PWI research institutions; 2) compare faculty experiences during the …

Synthesis And Evaluation Of Troponoids As A New Class Of Antibiotics, Feng Cao, Cari Orth, Maureen J. Donlin, Patrick Adegboyega, Marvin J. Meyers, Ryan P. Murelli, Mohamed Elagawany, Bahaa Elgendy, John E. Tavis

Publications and Research

Novel antibiotics are urgently needed. The troponoids [tropones, tropolones, and α-hydroxytropolones (α-HT)] can have anti-bacterial activity. We synthesized or purchased 92 troponoids and evaluated their antibacterial activities against Staphylococcus aureus, Escherichia coli, Acinetobacter baumannii, and Pseudomonas aeruginosa. Preliminary hits were assessed for minimum inhibitory concentrations (MIC80) and cytotoxicity (CC50) against human hepatoma cells. Sixteen troponoids inhibited S. aureus/E. coli/ A. baumannii growth by ≥80% growth at <30 >μM with CC50 values >50 μM. Two selected tropolones (63 and 285) inhibited 18 methicillin-resistant S. aureus (MRSA) strains with similar MIC80 values as against a reference strain. Two selected thiotropolones (284 and 363) …

Fractionation And Characterization Of Lignin Streams From Unique High-Lignin Content Endocarp Feedstocks, Wenqi Li, Kirtley Amos, Mi Li, Yunqiao Pu, Seth Debolt, Arthur J. Ragauskas, Jian Shi

Biosystems and Agricultural Engineering Faculty Publications

Background: Lignin is a promising source of building blocks for upgrading to valuable aromatic chemicals and materials. Endocarp biomass represents a non-edible crop residue in an existing agricultural setting which cannot be used as animal feed nor soil amendment. With significantly higher lignin content and bulk energy density, endo-carps have significant advantages to be converted into both biofuel and bioproducts as compared to other biomass resources. Deep eutectic solvent (DES) is highly effective in fractionating lignin from a variety of biomass feedstocks with high yield and purity while at lower cost comparing to certain ionic liquids.

A Multi-Task Approach To Incremental Dialogue State Tracking, Anh Duong Trinh, Robert J. Ross, John D. Kelleher

Conference papers

Incrementality is a fundamental feature of language in real world use. To this point, however, the vast majority of work in automated dialogue processing has focused on language as turn based. In this paper we explore the challenge of incremental dialogue state tracking through the development and analysis of a multi-task approach to incremental dialogue state tracking. We present the design of our incremental dialogue state tracker in detail and provide evaluation against the well known Dialogue State Tracking Challenge 2 (DSTC2) dataset. In addition to a standard evaluation of the tracker, we also provide an analysis of the Incrementality …

Judgments Of Lethal Risk: A Comparison Of Visual And Narrative Stimuli, Derek Anthony Bonniksen

Dissertations and Theses

The nature of how we make judgments has received a great deal of attention in the last few decades. Risk communication research has indicated that risk-related messages can elicit affective responses in audiences, which can then have a significant impact on how such audiences judge risk in general. Using a 2 x 2 between-subjects factorial design, this study found that, contrary to Johnson and Tversky's (1983) findings, presenting narratives about lethal risk does not influence readers' judgments about the frequency that risks occur, nor do such narratives influence participant worry levels about the lethal risks, more generally. Additionally, the inclusion …

Performance Of The Parallelized Monte-Carlo Tree Search Approach For Dots And Boxes, Pranay Agrawal, Uta Ziegler

Posters-at-the-Capitol

The Monte-Carlo tree search (MCTS) is a method designed to solve difficult learning problems. MCTS performs random simulations from the current situation and stores the results in order to distinguish decisions based on their past success. MCTS will then select the best decision and finally repeat the process. Parallelizing the MCTS means to divide the learning process among independent learners. Then, after a fixed number of simulations, the data is shared and combined. Past research has shown that this approach is faster than non-parallelized approaches. Therefore, we anticipated that the time reduced from dividing the learning outweighs the potential costs …

Variations Of Soil Qualities In Urban And Rural Areas, Gabby Barnes, Iin Handayani, Steve Still

Posters-at-the-Capitol

The purpose of this study was to evaluate the variations of soil characteristics under different management practices in rural soils versus urban soils. In this study, soil samples from rural areas in Kentucky were collected from a woodland plot, a no-till plot, and a tilled plot. The soil samples from the rural were taken from two depths in order to better evaluate the effect of tillage on the soil. A shallow depth of 0-7cm and a deep depth of 7-15cm were used. Soil samples were also taken from urban plots in Memphis, TN. The sampled plots included were an animal …

Dance Of Two Supermassive Binary Black Holes, Karishma Bansal

Shared Knowledge Conference

Black holes exist in a various range of masses ranging from stellar mass (~ 10 Solar Mass) to Supermassive black holes (SMBHs, million to billion Solar Mass). It is expected that as the separation between the black holes decreases, emission of gravitational waves will grow stronger, which makes binary black holes one of the most promising sources for gravitational radiation detection. Gravitational waves from merging stellar-mass black holes have recently been discovered by LIGO; however, we are yet to detect them from binary SMBHs. These massive black holes reside at the heart of most of the galaxies and when two …

High-Resolution Digital Surface Characterization Of The Rio Chama In New Mexico, Rowan L. Converse

Shared Knowledge Conference

Over the past eighty years, the Rio Chama, a major tributary of the Rio Grande in New Mexico, has been subject to significant disruption of historic hydrological flow regimes due to water use demands. In recent years, a multiagency management effort has been initiated to restore some measure of historic flow regimes in the 39.6 km congressionally designated Wild and Scenic stretch through the Rio Chama Canyon Wilderness. We collaborated with managers at the US Army Corps of Engineers to collect approximately 15,870 frames of 10cm resolution multispectral imagery of the 82 km stretch of the river between El Vado …

Are The Oxygen Isotope Values Of The Late Cretaceous Western Interior Seaway Different From The Open Ocean?, Camille H. Dwyer, Corinne Myers, Viorel Atudorei

Shared Knowledge Conference

The Western Interior Seaway (WIS) was a North American epicontinental sea that was connected to the open ocean through the passage of the northern Boreal Sea and the southern Tethys Sea from the early Albian (~113 million years ago) to the early Paleogene (~65 million years ago). The WIS began to recced and lost its connection to the southern Tethys Sea in the late Campanian (~72 million years ago). In the early Paleogene, the WIS dried up completely. The oxygen isotopic composition (δ18O) of benthic bivalves was measured from the upper Campanian and lower Maastrichtian (75 million years ago to …

Assessing Water Policy Implications Of The Changing Agriculture In New Mexico, Trevor A. Birt

Shared Knowledge Conference

Agriculture is the dominant water sector in New Mexico, responsible for more than 80% of water withdrawals in 2015 (USGS 2018). Water policy needs to be extremely adaptive and informed to meet the needs of not only farmers, but cities, industry and riparian uses. Since 1840, the U.S. Department of Agriculture (USDA) has conducted census surveys assessing all levels of agriculture. These data are physically published at the county, state, and national level on a 5-year cycle, detailing various material counts such as acreage, yields, and water usage, as well as socioeconomic estimates of farm costs, revenues, and hired workers. …
