White, James Clifford – ProQuest LLC, 2013
Understanding how people learn the phonological patterns of their language is a major challenge facing the field of phonology. In this dissertation, I approach the issue of phonological learning by focusing on "saltatory" alternations, which occur when two alternating sounds "leap over" an intermediate, invariant sound (e.g.,…

The development of scientifically literate citizens begins in the elementary school. Yet elementary school teachers are ill prepared to teach science (Trygstad, Smith, Banilower, Nelson, & Horizon Research, Inc., 2013). The research base on teacher preparation finds that programs designed to prepare elementary teachers are inadequate in…

The Digital Agenda for Europe (2015) states that there will be 825,000 unfilled vacancies for Information and Communications Technology by 2020. This lack of IT professionals stems from the small number of students graduating in computer science. To retain more students in the field, teachers can use remote robotic experiments to explain difficult…

Withana, Eran Chinthaka – ProQuest LLC, 2011
From time-critical, real time computational experimentation to applications which process petabytes of data there is a continuing search for faster, more responsive computing platforms capable of supporting computational experimentation. Weather forecast models, for instance, process gigabytes of data to produce regional (mesoscale) predictions on…

Cole, Robert – ProQuest LLC, 2013
Organizations in all sectors of business have become highly dependent upon information systems for the conduct of business operations. Of necessity, these information systems are designed with many points of ingress, points of exposure that can be leveraged by a motivated attacker seeking to compromise the confidentiality, integrity or…

Shanman, Derek – ProQuest LLC, 2013
In two experiments, I tested for the presence of conditioned seeing as a measureable behavior, which was measured by participants' accuracy in drawing a stimulus, and how this behavior was related to the demonstration of the naming capability. In Experiment 1, participants demonstrated a correlation between drawing responses and speaker…

Neu, Jessica Adele – ProQuest LLC, 2013
I conducted two studies on the comparative effects of the observation of learn units during (a) reinforcement or (b) correction conditions on the acquisition of math objectives. The dependent variables were the within-session cumulative numbers of correct responses emitted during observational sessions. The independent variables were the…

Melkonyan, Arsen – ProQuest LLC, 2013
Location technologies constitute an essential component of systems design for autonomous operations and control. The Global Positioning System (GPS) works well in outdoor areas, but the satellite signals are not strong enough to penetrate inside most indoor environments. As a result, a new strain of indoor positioning technologies that make use of…

Kleinman, Daniel Gregory – ProQuest LLC, 2013
This dissertation consists of three studies that investigate the extent to which speakers and listeners can and do plan ahead during production and comprehension. Study 1 investigates the attentional requirements of word selection. In two dual-task experiments, subjects categorized tones and then named pictures while word selection difficulty was…

Lam, Tuan Q. – ProQuest LLC, 2012
In conversation, speakers produce some words with greater intensity, longer duration, and higher fundamental frequency (F0) than other words. By making different words in a sentence more prominent than other words, a speaker can change the meaning implied by a sentence. This thesis explores the relationship between processing in the language…

Lim, Boon Pang – ProQuest LLC, 2011
Whispering is a common type of speech which is not often studied in speech technology. Perceptual and physiological studies show us that whispered speech is subtly different from phonated speech, and is surprisingly able to carry a tremendous amount of information. In this dissertation we consider the question: What makes whispering a good form of…

Srinivasan, Deepa – ProQuest LLC, 2013
Recent rapid malware growth has exposed the limitations of traditional in-host malware-defense systems and motivated the development of secure virtualization-based solutions. By running vulnerable systems as virtual machines (VMs) and moving security software from inside VMs to the outside, the out-of-VM solutions securely isolate the anti-malware…

With increasing Internet connectivity and traffic volume, recent intrusion incidents have reemphasized the importance of network intrusion detection systems for combating increasingly sophisticated network attacks. Techniques such as pattern recognition and the data mining of network events are often used by intrusion detection systems to classify…

Maron, Marta Katarzyna – ProQuest LLC, 2011
This dissertation is a combination of two research areas, experimental physical chemistry, Chapters I to V, and chemical education, Chapters VI to VII. Chapters I to V describe research on the water-mediated chemistry of oxidized atmospheric molecules and the impact that water has on the spectra of these environmental systems. The role of water…

Cognitive load theory (CLT) (Sweller 1988, 1998, 2010) provides us a guiding framework for designing instructional materials. CLT differentiates three subtypes of cognitive load: intrinsic, extraneous, and germane cognitive load. The three cognitive loads are theorized based on the number of simultaneously processed elements in working memory.…
