The Role Of Perception, Interpretation, And Decision Making In The Development Of Beginning Teachers’ Competence, Rossella Santagata, Cathery Yeh

Education Faculty Articles and Research

This study investigates beginning US elementary teachers’ competence for teaching mathematics and its development during teacher preparation and into the first 2 years of full-time teaching. Data are drawn from three longitudinal case studies and include the classroom video analysis survey, classroom observations and interviews about teachers’ instructional decisions, and whole-day shadowing. A multi-case study design was used to examine the processes of perception, interpretation, and decision making in participants’ comments on video clips of teaching episodes and in reflections about their own teaching. Findings support the central role of these processes in teacher competence and the generative power of …

Using An Agent-Based Model To Study The Effect Of Reproductive Skew On Mongoose Populations, Stacy Lee Mowry

Theses and Dissertations

Reproductive skew is the name given to the unequal partitioning of breeding

within social groups. Within these groups a mating hierarchy emerges wherein one dominant mating pair holds an unproportional majority of the group's reproductive benefit, while other members mate infrequently, yet allocate energy and resources toward the offspring of the dominant group members. In this paper, we use an agent-based model, which mimics dwarf and banded mongoose populations, to investigate how reproductive skew aftects the speed natural selection, and thus how reproductive skew affects fitness. The results of the model show that due to the geometric structure of skewed …

Predicting Phase Resetting Due To Multiple Stimuli, Kelsey M. Vollmer, Davy C. Vanderweyen, Derek R. Tuck, Sorinel A. Oprisan

Journal of the South Carolina Academy of Science

We generalized the phase resetting curve (PRC) to a more realistic case of neural oscillators receiving two or more inputs per cycle. The PRC tabulates the transient change in the firing period of a neuron due to an external perturbation, such as a presynaptic stimulus. We used a conductance-based model neuron to estimate experimentally the two-stimulus PRC and compared the results against our mathematical prediction based on the assumption of instantaneous recurrent stimulation. Within the limits of the recurrent stimulation assumptions, we found that the newly introduced prediction for the two-stimulus PRC matched experimental measurements. Our new results open the …

Minimum Richness Equilibrium And Sudoku, Jeffrey Horn

Conference Presentations

In the field of theoretical ecology the term "richness" refers to the number of species present in an ecosystem. By reducing the game of Sudoku to the problem of exact four cover (X4C), then reducing X4C to minimum richness equilibrium (MRE), we show that MRE is in NP-complete. We further reduce MRE to minimum weight linear programming (MWLP) to arrive at a simple, polynomial-time decision process that we demonstrate to be a pretty darn good Sudoku solver!

Give Up, Catch Up, Or Keep Up With Innovation? An Educator's Dilemma, Britta W. Mckenna

Publications & Research

Don't look now, but your students want more than the three R's for their school experience. Innovation, technology, entrepreneurship and the Maker Movement are changing what our students want to do and be in the future beyond what we can imagine today. Schools and teachers need to figure out how to respond to the DIY generation of makers emerging and be prepared to reshape education. In an information-rich age of smart phones, online learning, coding, gamification, apps, Internet of Things and digital badges, are today's schools ready for tomorrow's students?

Resource Sharing Begins At Home: Opportunities For Library Partnerships On A University Campus, Robert A. Seal

University Libraries: Faculty Publications and Other Works

Typical discussions of academic library resource sharing focus on activities between and among institutions: interlibrary loan, reciprocal borrowing, document delivery, group acquisitions, etc. But there is another equally important type of cooperation, i.e. working with other campus units to provide better service, more convenience, and enhanced resources for library users. Sometimes referred to as campus collaboration or convergence, this activity also advances institutional priorities, in particular that of student success. Library partners include information technology services, student development, writing centers, academic departments, and centers for teaching excellence, among others. This paper explores these relationships, their advantages and disadvantages, goals, the …

Classification, Visualization, And Analysis Of The Islamic State’S Narrative, Steven D. Bixler

Geography and the Environment: Graduate Student Capstones

The Islamic State (IS) declared the establishment of a Caliphate on June 29, 2014 in Mosul, Iraq. Since that declaration, IS has communicated a four-part narrative to the global community through Dabiq magazine, its e-publication. Each of the ten editions of Dabiq has provided insight into IS’s aspirations and reinforced its message of rejecting post-colonial structures. Critical to realizing its objective is establishing a foothold for the Caliphate through jihad (holy war), establishing legitimacy through jamaah (governance), achieving tawhid (unity), and expanding through hijrah (immigration). Each publication contains these narrative elements to document IS’s progress. Classifying, visualizing, and mapping will …

Declining Survivor Benefits And Labor Force Participation, Amanda Geary

Kaleidoscope

Social Security Survivor Benefits aim to mitigate the problem of raising children on a single income by granting a widow monthly payments in her child’s name. However, as each child reaches the age of 18 (or 19, if he or she is attending elementary or high school full-time) his or her benefits are discontinued. As is increasingly common in today’s society, simply turning 18 is not indicative of financial independence. This paper attempts to discern whether a widow changes labor force habits when her children become legal adults and survivor benefits are reduced or discontinued. Though many of my results …

A Comparative Legal Approach For The Risks Of Offshore Methane Hydrates: Existing Laws And Conventions, Roy Andrew Partain

Pace Environmental Law Review

This article provides a review of the existing laws and conventions that might be applied to the development of offshore methane hydrates. Offshore methane hydrates are an exciting emerging new energy resource; one with great potential to provide vast energy supplies, and also one with substantially novel risks and hazards to the environment, marine flora and fauna, and adjacent human communities. Some of these new risks include cataclysmic levels of greenhouse gas emissions, subsea landslides, and tsunamis. As such, it is important to take a survey of the existing laws and conventions that could be applied to such risks, examine …

Aribo, De Musica And Sententiae, T. J. H. Mccarthy

TEAMS Varia

Music was central to the medieval church's public worship: it was the essential medium of the Mass and the Divine Office. In this new critical edition, T. J. H. McCarthy presents the Latin text and the first English translation of Aribo's musical treatise, De musica and Sententiae. Written between 1070 and 1078, it is concerned with the workings of the liturgical music that Aribo and his contemporaries called Gregorian chant, and builds off of and responds to several contemporary treatises by Abbot Bern of Reichenau and his pupil Herman, Abbot William of Hirsau, Frutolf of Michelsberg, and Theoger of Metz. …

Mid-Infrared Optical Frequency Combs Based On Difference Frequency Generation For Molecular Spectroscopy, Flavio C. Cruz, Daniel L. Maser, Todd Johnson, Gabriel Ycas, Andrew Klose, Fabrizio R. Giorgetta, Ian Coddington, Scott A. Diddams

Physics Faculty Publications

Mid-infrared femtosecond optical frequency combs were produced by difference frequency generation of the spectral components of a near-infrared comb in a 3-mm-long MgO:PPLN crystal. We observe strong pump depletion and 9.3 dB parametric gain in the 1.5 μm signal, which yields powers above 500 mW (3 μW/mode) in the idler with spectra covering 2.8 μm to 3.5 μm. Potential for broadband, high-resolution molecular spectroscopy is demonstrated by absorption spectra and interferograms obtained by heterodyning two combs.

Effects Of Oil-Contaminated Sediments On Submerged Vegetation: An Experimental Assessment Of Ruppia Maritima, Charles W. Martin, Lauris O. Hollis, R. Eugene Turner

Faculty Publications

Oil spills threaten the productivity of ecosystems through the degradation of coastal flora and the ecosystem services these plants provide. While lab and field investigations have quantified the response of numerous species of emergent vegetation to oil, the effects on submerged vegetation remain uncertain. Here, we discuss the implications of oil exposure for Ruppia maritima, one of the most common species of submerged vegetation found in the region affected by the recent Deepwater Horizon oil spill. We grew R. maritima in a range of manipulated sediment oil concentrations: 0, 0.26, 0.53, and 1.05 mL oil /L tank volume, and tracked …

Generation Of A Novel Exactly Solvable Potential, Jonathan Bougie, Asim Gangopadhyaya, Jeffry V. Mallow, Emeritus, Constantin Rasinariu

Physics: Faculty Publications and Other Works

We report a new shape-invariant (SI) isospectral extension of the Morse potential. Previous investigations have shown that the list of “conventional” SI superpotentials that do not depend explicitly on Planck's constant ħ is complete. Additionally, a set of “extended” superpotentials has been identified, each containing a conventional superpotential as a kernel and additional ħ-dependent terms. We use the partial differential equations satisfied by all SI superpotentials to find a SI extension of Morse with novel properties. It has the same eigenenergies as Morse but different asymptotic limits, and does not conform to the standard generating structure for isospectral deformations.

Do Mindfulness, Rumination Or Social Problem-Solving Factors Predict Distress?, Gabriela Lopez

Theses and Dissertations

Depression and anxiety continue to be prevalent concerns, with lifetime prevalence rates of 41% for depressive symptoms and 15% for anxious symptoms. Reputable studies confirm that high self-reported mindful awareness and social problem solving are both individually related to a lower severity of self-reported depressive symptoms. Rumination has also been found to have a significant relationship with depressive and anxious symptoms. Yet, these etiological factors have not been studied in combination, which is the focus of the current study. Hypothesis 1: Mindfulness, rumination, and social problem-solving will predict depressive symptoms after controlling for the variance predicted by Time 1 (T1) …

The Nicotine Metabolite, Cotinine, Alters The Assembly And Trafficking Of A Subset Of Nicotinic Acetylcholine Receptors, Ashley M. Fox, Faruk H. Moonschi, Christopher I. Richards

Chemistry Faculty Publications

Exposure to nicotine alters the trafficking and assembly of nicotinic receptors (nAChRs), leading to their up-regulation on the plasma membrane. Although the mechanism is not fully understood, nicotine-induced up-regulation is believed to contribute to nicotine addiction. The effect of cotinine, the primary metabolite of nicotine, on nAChR trafficking and assembly has not been extensively investigated. We utilize a pH-sensitive variant of GFP, super ecliptic pHluorin, to differentiate between intracellular nAChRs and those expressed on the plasma membrane to quantify changes resulting from cotinine and nicotine exposure. Similar to nicotine, exposure to cotinine increases the number of α4β2 receptors on the …

First Observation Of The Hadronic Transition Υ(4s)→Ηhb(1p)And New Measurement Of The Hb(1p) And Ηb(1s) Parameters, U. Tamponi, R. Mussa, A. Abdesselam, H. Aihara, K. Arinstein, D. Joffe

Faculty Publications

The CARIACO Ocean Time Series program has made monthly measurements of oxygen, nutrients, and carbon system parameters (∑CO2, alkalinity, pH) in the Cariaco Basin since 1996. At the same time, sediment traps have collected settling particles at four to five depths ranging from 150 to 1,200 m. The depth of the transition from oxic to anoxic conditions has fluctuated dramatically over the time series due to changes in the occurrence of Caribbean water intrusions into the deep basin. Nutrient concentrations in the deep basin have increased steadily with time in a proportion reflective of the elemental ratios in the settling …

Heat Transfer Mechanisms In Porous Materials And Contemporary Problems In Thermophysical Properties Investigations: Analyses And Solutions, E. Litovsky, V. Issoupov, J. Kleiman

International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES)

This article is an overview of the topical problems in the investigation of thermophysical properties and the development of a database for porous materials. Determination of both apparent/measured and true thermophysical properties is discussed taking into account combined heat and mass transfer, latent heat effects during chemical and physical transformations, as well as structural changes. The approaches to the solution of these problems are demonstrated for a number of different classes of materials:

1. Industrial refractories, ceramics, highly porous insulation;
2. Moist materials and materials undergoing phase, chemical and structural transformations;
3. Materials semitransparent for heat radiation.

The approaches being used in the …
