How Does The Use Of Picture Books During Instruction Improve Student Word Choice In Writing?, Laurie Anne Mcadams
How Does The Use Of Picture Books During Instruction Improve Student Word Choice In Writing?, Laurie Anne Mcadams
Electronic Theses and Dissertations
The purpose of my research was to determine how the use of picture books during instruction would improve student word choice in writing. Donald Graves (2003), a renowned researcher in the teaching of writing, states, "All children need . . . to be surrounded with poetry, stories, information books, biography, science and history, imaginative and factual books." Graves' research presents successful classroom instruction when teachers incorporate literature as a fundamental part of their reading and writing instruction. Likewise, Susan Anderson McElveen and Connie Campbell Dierking (2000) conducted a study with their students using picture books as "precise examples" to teach …
Spectral Signature Modification By Application Of Infrared Frequency-Selective Surfaces, Brian Monacelli
Spectral Signature Modification By Application Of Infrared Frequency-Selective Surfaces, Brian Monacelli
Electronic Theses and Dissertations
It is desirable to modify the spectral signature of a surface, particularly in the infrared (IR) region of the electromagnetic spectrum. To alter the surface signature in the IR, two methods are investigated: thin film application and antenna array application. The former approach is a common and straightforward incorporation of optically-thin film coatings on the surface designated for signature modification. The latter technique requires the complex design of a periodic array of passive microantenna elements to cover the surface in order to modify its signature. This technology is known as frequency selective surface (FSS) technology and is established in the …

Affective Design In Technical Communication, Michael Alan Rosen
Affective Design In Technical Communication, Michael Alan Rosen
Electronic Theses and Dissertations
Traditional human-computer interaction (HCI) is based on 'cold' models of user cognition; that is, models of users as purely rational beings based on the information processing metaphor; however, an emerging perspective suggests that for the field of HCI to mature, its practitioners must adopt models of users that consider broader human needs and capabilities. Affective design is an umbrella term for research and practice being conducted in diverse domains, all with the common thread of integrating emotional aspects of use into the creation of information products. This thesis provides a review of the current state of the art in affective …

The literature revealed that the girls who do not pursue STEM endeavors in great numbers do not perceive mathematics as a useful endeavor …
A Dialectical Methodology For Decision Support Systems Design, Wafa Elgarah
A Dialectical Methodology For Decision Support Systems Design, Wafa Elgarah
Electronic Theses and Dissertations
As organizations continue to grow in size, reaching global proportions, they have ever increasing impacts on their environments. Some believe that a much broader array of concerns should be brought into organizational decision-making processes, including greater consideration of social, political, ethical and aesthetic factors (Mitroff and Linstone, 1993; Courtney, 2001). Decision environments such as these are decidedly "wicked" (Rittel and Webber, 1973). Designing decision support systems in such environments where there is a high level of interconnectedness, issues are overlapping and a multiplicity of stakeholders is involved, is a very complex task. In this dissertation a methodology for the development …
Assessment And In Vitro Repair Of Damaged Dna Templates From Forensic Stains, Ashley Hall
Assessment And In Vitro Repair Of Damaged Dna Templates From Forensic Stains, Ashley Hall
Electronic Theses and Dissertations
DNA extracted from biological stains is often intractable to analysis. This may due to a number of factors including a low copy number (LCN) of starting molecules, the presence of soluble inhibitors or damaged DNA templates. Remedies may be available to the forensic scientist to deal with LCN templates and soluble inhibitors but none presently exist for damaged DNA. In fact, only recently has the biochemical nature, the extent of DNA damage in physiological stains and the point at which the damage inflicted upon a particular sample precludes the ability to obtain a genetic profile for purposes of identification been …

This mixed-methods research examined student nurse retention methods perceived as best practice by directors and coordinators in selected Associate Degree Nursing (AND) programs within the Florida Community College System (FCCS). A critical nursing shortage is expected to worsen over the next twenty years due to the aging workforce and the inadequate supply of qualified nurse graduates. The Associate degree nursing programs supply the majority of nursing graduates to the workforce. Thus, the associate degree nursing programs and student retention measures were studied. The research was conducted using a Delphi survey of directors of nursing in ADN programs within the FCCS. …
Time Estimation And Hand Preference, Maria Rodriguez
Time Estimation And Hand Preference, Maria Rodriguez
Electronic Theses and Dissertations
This work examines the effect of participants' gender and handedness on the perception of short intervals of time. The time estimation task consisted of an empty production procedure with forty trials at each of four intervals of one, three, seven, and twenty seconds. The four target intervals represent a natural logarithmic progression and a series that bracket important temporal thresholds. The order of presentation of those intervals was randomized across participants but yoked across the sexes in each of the respective dominant hand groups. The two between-subject factors, with two levels each, were sex and handedness. Participants produced forty estimates …

Structural Study Of Disease Related Proteins, Ayse Sinem Ozyurt
Structural Study Of Disease Related Proteins, Ayse Sinem Ozyurt
Electronic Theses and Dissertations
The availability of complete sequences for the genomes of many organisms changes the researcher's attention from genome sequencing to finding the function of gene products, the proteins. The three dimensional (3D) structure of a protein is helpful to understand its function, because tertiary structure is more conserved in evolution than sequence. The 3D structures can be found quickly by using high-throughput (HT) methods for protein expression, purification, characterization and structure determination. This process is very challenging in every step. Therefore we selected nearly 200 cancer related proteins as targets to see the difficulties in trying to determine the web predicted …

The assumption was that the students who utilized the services of the Academic Center for Excellence would demonstrate more increases in GPA than students who did not utilize the services. The literature review of this study found that, although there were many factors and student characteristics that could predict and explain student achievement in course work, …
Design And Assessment Of Compact Optical Systems Towards Special Effects Imaging, Vesselin Chaoulov
Design And Assessment Of Compact Optical Systems Towards Special Effects Imaging, Vesselin Chaoulov
Electronic Theses and Dissertations
A main challenge in the field of special effects is to create special effects in real time in a way that the user can preview the effect before taking the actual picture or movie sequence. There are many techniques currently used to create computer-simulated special effects, however current techniques in computer graphics do not provide the option for the creation of real-time texture synthesis. Thus, while computer graphics is a powerful tool in the field of special effects, it is neither portable nor does it provide work in real-time capabilities. Real-time special effects may, however, be created optically. Such approach …
The Relationship Of Parent And Child Self-Talk In A College Sample, Reesa Donnelly
The Relationship Of Parent And Child Self-Talk In A College Sample, Reesa Donnelly
Electronic Theses and Dissertations
Research has demonstrated the importance of early social interactions in the development of self-talk. It does not appear, however, that existing research has examined the relationship between parents' self-talk and the self-talk that develops in their children. This study examined the relationship between self-talk in parents and their college-age children. Results revealed significant relationships between students' and parents' positive self-talk, but not negative self-talk. Marginal relationships were found for self-talk ratios (ratios of positive and negative self-talk). Maternal communication was found to mediate the relationship between students' and their mothers' positive self-talk. Different trends also were noted between genders. Finally, …

Formalization Of Input And Output In Modern Operating Systems: The Hadley Model, Matthew Gerber
Electronic Theses and Dissertations
We present the Hadley model, a formal descriptive model of input and output for modern computer operating systems. Our model is intentionally inspired by the Open Systems Interconnection model of networking; I/O as a process is defined as a set of translations between a set of computer-sensible forms, or layers, of information. To illustrate an initial application domain, we discuss the utility of the Hadley model and a potential associated I/O system as a tool for digital forensic investigators. To illustrate practical uses of the Hadley model we present the Hadley Specification Language, an essentially functional language designed to allow …

A Dynamic Model Of The Human/Cooling System/Clothing/Environment System, Zhengxiang Pu
A Dynamic Model Of The Human/Cooling System/Clothing/Environment System, Zhengxiang Pu
Electronic Theses and Dissertations
The human body compensates well for moderate climatic heat stress, but artificial environments often block or overwhelm physiological defense mechanism. Personal protective equipment (PPE) is one of sources of heat stress. It protects individual from chemical, physical, or biological hazards, but the high thermal insulation and low vapor permeability of PPE may also lead to substantial heat stress. Personal cooling is widely used to alleviate heat stress, especially for those situations where ambient environmental cooling is not economically viable or feasible. It is important to predict the physiological responses of a person wearing PPE with personal cooling to make sure …
