Technology use has become commonplace in some mathematics classrooms, often being used for formative assessment. Research supports the use of technology to engage students, but not as much research exists to investigate the impact on student learning. The purpose of this study was to investigate whether a statistical relationship exists between the post-lesson assessment results of students engaging in a formative assessment lesson where the teacher delivers the lesson with technology and students engaging in a formative assessment lesson where the teacher delivers the lesson without technology. The teachers administered pre- and post-lesson assessments to the students after the formative …
Going To Bat: Assessing Disgust Sensitivity And Related Factors In Behavioral Avoidance, Molly E. Wickenhauser
Going To Bat: Assessing Disgust Sensitivity And Related Factors In Behavioral Avoidance, Molly E. Wickenhauser
Electronic Theses and Dissertations
The present study used archival data (N = 194) consisting of responses from a battery of questionnaires and data from eight behavioral avoidance tasks (BATs). Correlational analyses demonstrated that disgust sensitivity, anxiety sensitivity, state disgust and anxiety ratings during BATs, and behavioral avoidance on BATs were significantly correlated. Higher disgust sensitivity and behavioral avoidance was also associated with being female. Unexpectedly, emotion dysregulation was not correlated with disgust sensitivity or behavioral avoidance. Next, a series of hierarchical multiple linear regressions indicated that the contamination disgust domain appeared to be the strongest predictor of behavioral avoidance on core- and contamination-related BATs, …

Dynamic Code Selection Method For Content Transfer In Deep Space Network, Rojina Adhikary
Electronic Theses and Dissertations
Space communications feature large round-trip time delays (for example, between 6.5 and 44 minutes for Mars to Earth and return, depending on the actual distance between the two planets) and highly variable data error rates, for example, bit error rate (BER) of 10−5 is very comand even higher BERs on the order of 10−1 is observed in the deep- space environment. We develop a new content transfer protocol based on RaptorQ codes and turbo codes together with a real-time channel prediction model to maximize file transfer from space vehicles to the Earth stations. While turbo codes are used to correct …
Manifoldlike Causal Sets, Miremad Aghili
Manifoldlike Causal Sets, Miremad Aghili
Electronic Theses and Dissertations
The content of this dissertation is written in a way to answer the important question of manifold likeness of causal sets. This problem has importance in the sense that in the continuum limit and in the case one finds a formalism for the sum over histories, the result requires to be embeddable in a manifold to be able to reproduce General Relativity. In what follows I will use the distribution of path length in a causal set to assign a measure for manifold likeness of causal sets to eliminate the dominance of nonmanifold like causal sets. The distribution of interval …

Effects Of Impoundments On The Community Assemblage And Gene Flow Of Stream Crayfishes, Zanethia Choice Barnett
Electronic Theses and Dissertations
Dams and their impoundments block movement of stream organism and change stream physiochemical properties, which subsequently changes biological assemblages and creates barriers to gene flow. While changes in species assemblages and gene flow have been assessed for numerous impoundments and stream organisms, no study has assessed the effects of large impoundments on crayfish assemblages and population genetic diversity and connectivity. I examined the physiochemical, biological, and genetic effects of impoundments on crayfishes. Between May 2015 and August 2017, I sampled multiple sites up- and downstream of three impounded streams, and along the lengths of two unimpounded streams, in the Bear …

Techno-Economic And Sustainability Study Of Pv Inverter Controllers In Distribution Networks For Voltage Regulation, Kapil Duwadi
Techno-Economic And Sustainability Study Of Pv Inverter Controllers In Distribution Networks For Voltage Regulation, Kapil Duwadi
Electronic Theses and Dissertations
Increasing distributed solar installations in low voltage distribution grids tend to increase the feeder voltage. The rise in voltage is only acceptable to a certain limit, and control strategies are required to keep voltage within defined bounds for equipment safety and system reliability. PV inverter control strategies are cost-effective methods to prevent overvoltage. Different inverter control strategies have different impacts on their techno-economic performance, ultimately affecting their sustainability. An evaluation framework for long-term techno-economic and sustainability analysis of overvoltage prevention methods in PV-rich LV networks is proposed to decide suitable control methods by making use of quasi-steady-state time-series (QSTS) software …
Role Of Microglial Α7 Nicotinic Acetylcholine Receptor Positive Allosteric Modulator In Animal Model Of Major Depressive Disorder, Sami Alzarea
Electronic Theses and Dissertations
Major depressive disorder (MDD) is the most prevalent psychiatric disorder, affecting about 10% of the global population and is the leading cause of disability in USA. Nearly one-third of depressed patients fail to respond to conventional antidepressant therapies. Therefore, novel therapies are needed, and require a new target and molecular mechanisms underlying MDD. Brain glial mechanisms, specifically, microglial α7 nicotinic acetylcholine receptors (nAChRs) have been proposed as an important target for MDD associated with neuroinflammation. We hypothesized that microglial α7 nAChRs positive allosteric modulator (PAM) has an important role in the regulation of behavioral, cellular, biochemical and molecular mechanisms underlying …

Advanced Analysis Of Compounds Of Toxicological Importance By Ice Concentration Linked With Extractive Stirrer (Icecles) Gc-Ms And Rp-Hplc-Esi-Ms-Ms, Joseph K. Dzisam
Electronic Theses and Dissertations
Cyanide and nitrosoamines (NAs) are ubiquitous compounds, found in our food and water, either by natural process or through man-made activities. The toxicity of cyanide is exerted by its ability to inhibit metalloenzymes such as cytochrome c oxidase, causing concomitant cascades of biochemical effects such as lactic acidosis, inhibition of ATP production, respiratory seizure, and potential death. Nitrosoamines, on the other hand, undergo biotransformation (metabolic activation in cytochrome P450) in the body to produce unstable intermediates that alkylate DNA, causing mutations, and leading to carcinogenesis. In order to further the advancement of a promising cyanide, cobinamide (Cbi), an LC-MS-MS method …

Diversifying Cornfields By Interseeding Cover Crops: Practical Implications And The Response Of Invertebrate Communities, Michael Bredeson
Diversifying Cornfields By Interseeding Cover Crops: Practical Implications And The Response Of Invertebrate Communities, Michael Bredeson
Electronic Theses and Dissertations
The lack of suitable habitat conditions for beneficial organisms in simplified agroecosystems leads to unstable invertebrate communities and overreliance on chemical control of herbivores. It is possible to manage pest populations without agrichemicals by manipulating farmland so that herbivores are impaired by plant-driven bottom-up and enemy-driven top-down antagonisms. Interseeding cover crops between established crop rows is a method used by farmers to improve habitat suitability for natural enemies and hinder host-finding, feeding and movement by herbivores. Here I address three important research gaps related to interseeding cover crops. A calcium carbonate seed coating, used to improve seed-broadcasting efficiency, was tested …
