Constructing A Sense Of Story: One Block At A Time, Joanne Robertson-Eletto, Smita Guha, Marina Marinelli
The Language and Literacy Spectrum
This photo essay focuses upon the literacy practices of two groups of preschoolers as they built, illustrated, and dictated stories in response to their participation in a “Castle Project.” Data, including literacy artifacts, photodocumentation, sociodramatic play scenarios, and conversations are qualitatively analyzed, coded, and evaluated over a three month period. We use a narrative approach to describe the three- and four-year-olds’ talk, actions, and ideas, and the ways block play facilitated their sense of story and motivation to write. We suggest a reciprocity of thinking between the building and composing processes. Preschoolers’ story ideas, we deduce, were conceptualized and rehearsed …

Glycerol dialkyl glycerol tetraethers (GDGTs) are membrane-spanning lipids from Bacteria and Archaea that are ubiquitous in a range of natural archives and especially abundant in peat. Previous work demonstrated that the distribution of bacterial branched GDGTs (brGDGTs) in mineral soils is correlated to environmental factors such as mean annual air temperature (MAAT) and soil pH. However, the influence of these parameters on brGDGT distributions in peat is largely unknown. Here we investigate the distribution of brGDGTs in 470 samples from 96 peatlands around the world with a broad mean annual air temperature (−8 to 27 °C) and pH (3–8) range …
Special Education Teachers' Experiences And Perceptions Of Instructing Students With Learning Disabilities, Kala Harris Johnstone
Special Education Teachers' Experiences And Perceptions Of Instructing Students With Learning Disabilities, Kala Harris Johnstone
Walden Dissertations and Doctoral Studies
An urban middle school in the northeastern United States was having a problem with low performance on state annual reading tests on the part of students with learning disabilities. Consequently, the middle school was not meeting the reading academic targets that were set by the Department of Education in the northeastern United States. The purpose of this exploratory qualitative case study was to explore special education teachers' experiences and perceptions about how teaching reading to students with learning disabilities was affecting special education teachers' pedagogy. Glasser's choice theory, which theorizes that an individual's behavior is chosen, formed the conceptual framework.- …
Strategies For Retaining Employees For Call Centers, Kimberly M. Combs
Strategies For Retaining Employees For Call Centers, Kimberly M. Combs
Walden Dissertations and Doctoral Studies
Voluntary employee turnover has several adverse consequences for call center managers, including lowered productivity and decreased profitability. The purpose of this descriptive multiple case study was to explore strategies used to reduced voluntary employee turnover among 2 call center managers in the southern United States. These managers had been recommended by the human resource directors of the organizations because of their implementation of strategies to reduce voluntary employee turnover. The conceptual framework for this study was Herzberg's motivation-hygiene theory. Data were collected from semistructured face-to-face interviews and employee handbooks. The data analysis consisted of compiling the data, disassembling the data …

A Meta-Analytic Review Of Play Therapy With Emphasis On Outcomes Measures, Scott A. Jensen, Judith N. Biesen, Elizabeth R. Graham
College of the Pacific Faculty Articles
A meta-analysis of 100 studies of outcomes of play therapy interventions was conducted to determine overall effect of intervention. Different from the Bratton, Ray, Rhine, and Jones (2005), but more consistent with the Lin and Bratton (2015), findings, there was a significant moderate effect for play therapy interventions across all outcomes (d = .44). When 4 studies with aberrantly large effects were removed, this effect was d = .36. These moderate effects are consistent with other meta-analyses that find lower effect sizes for nonbehavioral interventions. Overall study quality was poor with no studies meeting the criteria of randomized control trials. …

Modulation Of H-Reflex Depression With Paired-Pulse Stimulation In Healthy Active Humans, Preeti Deshpande Oza, Shauna Dudley-Javoroski, Richard K. Shields
School of Pharmacy Faculty Articles
Depression of the Hoffman reflex (H-reflex) is used to examine spinal control mechanisms during exercise, fatigue, and vibration and in response to training. H-reflex depression protocols frequently use trains of stimuli; this is time-consuming and prevents instantaneous assessment of motor neuronal excitability. The purpose of this study was to determine if paired-pulse H-reflex depression is reproducible and whether paired-pulse stimulation adequately estimates the depression induced by the more traditional ten-pulse train. H-reflexes were elicited via ten-pulse trains at 0.1, 0.2, 1, 2, and 5 Hz in ten neurologically intact individuals on two separate days. We measured the depression elicited by …

Efficient Reasoning Algorithms For Fragments Of Horn Description Logics, David Carral
Browse all Theses and Dissertations
We characterize two fragments of Horn Description Logics and we define two specialized reasoning algorithms that effectively solve the standard reasoning tasks over each of such fragments. We believe our work to be of general interest since (1) a rather large proportion of real-world Horn ontologies belong to some of these two fragments and (2) the implementations based on our reasoning approach significantly outperform state-of-the-art reasoners. Claims (1) and (2) are extensively proven via empirically evaluation.

Novel Implementation Of Finite Field Multipliers Over Gf(2m) For Emerging Cryptographic Applications, Nazeem Basha Shaik
Browse all Theses and Dissertations
Cryptographic and coding theory algorithms use arithmetic operations over finite fields. Finite field multiplications over GF(2m) are critical components for these systems. Well known irreducible polynomials are all-one-polynomials (AOP), equally spaced polynomial (ESP), trinomial and pentanomial. Due to its simple structure, AOP based multiplica- tion is easy to implement and hence the AOP based multiplication of variable length can be used as a standard computation core. In this thesis, first of all, we employ low register complexity AOP based systolic multiplication core to propose multiplication over GF(2m) based on NIST recommended pentanomials. The proposed parallel and serial ar- chitectures use …

The success of any multiplayer game depends on the player’s experience. Cheating/Hacking undermines the player’s experience and thus the success of that game. Cheaters, who use hacks, bots or trainers are ruining the gaming experience of a player and are making him leave the game. As the video game industry is a constantly increasing multibillion dollar economy, it is crucial to assure and maintain a state of security. Players reflect their gaming experience in one of the following places: multiplayer chat, game reviews, and social media. This thesis is an exploratory study where our goal is to experiment and propose …

The Synthesis Of 3,5-Difluorobenzophenone Derivatives And Their Corresponding Peek Copolymers, Rachael Stuck
Browse all Theses and Dissertations
Poly(aryl ether ketone)s (PAEK) are high performance thermoplastics, which are chemically robust, semi-crystalline, and stable at high temperatures. Of the family of PAEKs, poly(ether ether ketone) (PEEK) is a well-known semi-crystalline thermoplastic widely used for electronics, energy, industrial, and medical applications due to its resistance to solvents, radiation, heat, and other environmental factors. The traditional PEEK is prepared from 4,4’-difluorobenzophenone (2) and disodium hydroquinone. However, a challenge is processability, since due to its highly crystalline nature, PEEK possesses very limited solubility. An approach to solve these issues is to pre-functionalize PEEK polymers synthesized by nucleophilic aromatic substitution from 3,5-difluorobenzophenone (1) …

The synthesis of functionalized, linear poly (ether ether ketone), tailored to be semi-crystalline and soluble in a variety of organic-solvents was explored. Nucleophilic aromatic substitution was a chemical reaction method used to condense 3,5,4’-trifluorobenzophenone (TFK) with four different phenols at its para-positioned carbon-fluorine site: 4-methoxyphenol, 3-aminophenol, 4-bromophenol, and m-cresol. Further poly-condensation of functionalized TFK occurred at the meta-positioned carbon-fluorine sites with 4,4’-Bis[4-hydroxyphenoxy] benzophenone (Big A2) and 4,4’-difluorobenzophenone at molar equivalents of 1 to 0.5, respectively. The reaction afforded products that became insoluble in solvents needed for nuclear magnetic resonance spectroscopic (e.g. DMSO-d6) analysis. The lack of desirable compounds compelled the …

The current research examined the role of global properties in human observers' scene perception. In Experiment 1, comparisons of four global properties ("natural", "manmade", "open", and "closed") were collected online from a wide range of subjective choices. These answers were analyzed in a pairwise comparison model to generate four standardized reference ranking scales describing the extent to which characteristics can describe scene global properties. In Experiment 2, scene images selected from the reference scales were used to test human's performance in processing global properties conjunctively. Cognitive modeling indicated that human observers were more efficient in categorizing scene images as "natural …

Exploring The Time-Based Resource-Sharing Model Of Working Memory Through Computational Modeling, Joseph Glavan
Browse all Theses and Dissertations
Working memory is the fundamental component of cognition that allows us to temporarily maintain information needed for concurrent processing. An existing theory from the literature, the time-based resource-sharing (TBRS) model, posits that working memory is a serial, rapidly switching, attentional refreshing mechanism. While others have sought previously to formalize the TBRS model into a computational process model, I go further, using ACT-R to model the influence of working memory on an entire task from end to end. I leverage ACT-R's existing base-level learning mechanism, typically used to model recency and frequency effects in long-term memory, to enact the attentional refreshing …

Sched-Its: An Interactive Tutoring System To Teach Cpu Scheduling Concepts In An Operating Systems Course, Bharath Kumar Koya
Browse all Theses and Dissertations
Operating systems is an essential course in computer science curriculum, which helps students to develop a mental model of how computer operating systems work. The internal mechanisms and processes of an operating system (OS) are often complex, non-deterministic and intangible which makes them difficult for students to understand. One such concept is central processing unit (CPU) scheduling. CPU scheduling forms the basis of the multiprogramming in an OS. In practice, OS courses involve classroom lectures describing high-level abstractions of the concepts, and students complete programming assignments to apply the material in a more concrete way. Depending on the programming assignments, …
