Children with Emotional and Behavioral Disorders in Saudi Arabia: A Preliminary Prevalence Screening

Description: Education in Saudi Arabia, including the education of children with special needs, is developing rapidly. However, children with emotional and behavioral disorders are neither consistently identified nor adequately served in Saudi Arabia although they are recognized as a distinct category of children who require special education services. The goal of this study was to examine the prevalence of emotional and behavioral disorders among children in Saudi Arabia to assess the need for intervention services to help those children reach their potential. The current research identified the types of behaviors that are most evident in the study sample. Also, the relationship between demographics and emotional and behavioral disorders is studied to identify possible predictors of disruptive forms of behavior. Parents of children aged 4-17 years in Saudi Arabia were surveyed using the Strengths and Difficulties Questionnaire. The findings of the study suggest that children with emotional and behavioral disorders in Saudi Arabia may account for 20% of the population of children between the ages of 4 and 17. The findings also revealed that over 20% of children in Saudi Arabia have difficulties in peer relationship and lack the necessary prosocial behaviors. The parent reporting, child gender, child education type, the geographical region, the father's education level, and the family's socioeconomic status were found to be statistically significant predictors of children's difficulties. However, these predictors were only able to explain a small portion of the difficulty scores.

El Cine De Terror Español Como Espejo De La Cultura Española

Description: This study traces the history and culture of Spain as seen through the lens of the nation´s production of horror cinema. Starting from the boom of Spanish horror film in the early 1960s, the thesis compares and contrasts the political and social aspects of Spanish society throughout three distinct eras of the 20th century: 1962 – 1975 (the boom of Spanish horror film through the Franco dictatorship), 1975 – 1999 (the transition to democracy through the end of the 20th century) and 2000 – present (the 21st century). Movies as diverse as Gritos en la noche (1962, Jesús Franco), ¿Quién puede matar a un niño? (1976, Narciso Ibáñez Serrador) and Angustia (1987, Bigas Luna) are framed by culturally-related anectodes as well as correlations to their respective social environments. Special attention has been paid to the production and release of each film, especially in regards to censorship during the Franco dictatorship. The results show that Spanish horror cinema has acted as a true mirror to culture, society and politics in its native country throughout the 20th century and that this trend will likely extend in to the future.

Civil Liberties and National Unity: Reaction to the Sedition Act in the Southern States, 1798

Description: The traditional narrative of political party development in the United States of America during the latter half of the 1790s ascribes the decline in popularity of the Federalist Party in the Election of 1800 to that party's passage of controversial legislation, specifically the Sedition Act of 1798, prior to the election. Between the passage of the Sedition Act and the Election of 1800, however, the midterm elections of 1798-1799 transpired and resulted in a significant increase in Federalist popularity in four states – North Carolina, South Carolina, Georgia, and Virginia. This study seeks to ascertain why these four states increased their support for the Federalist Party in 1798-1799, despite the passage of the Sedition Act by the Federalist Party. By examining newspapers and election results, this study analyzes the reaction of these four states to the passage of the Sedition Act and finds that generally, these states did not react strongly against the Sedition Act in the immediate aftermath of its passage. Instead, all four states urged national unity and emphasized the need to support the national government because the United States faced the threat of war with France. This study employs a state-by-state formula to determine each state's individual reaction to the Sedition Act and the Quasi-War, finding that ultimately, the Sedition Act did not have as significant of an impact in these states as the popular narrative holds.

Collective Security and Coalition: British Grand Strategy, 1783-1797

Description: On 1 February 1793, the National Convention of Revolutionary France declared war on Great Britain and the Netherlands, expanding the list of France's enemies in the War of the First Coalition. Although British Prime Minister William Pitt the Younger had predicted fifteen years of peace one year earlier, the French declaration of war initiated nearly a quarter century of war between Britain and France with only a brief respite during the Peace of Amiens. Britain entered the war amid both a nadir in British diplomacy and internal political divisions over the direction of British foreign policy. After becoming prime minister in 1783 in the aftermath of the War of American Independence, Pitt pursued financial and naval reform to recover British strength and cautious interventionism to end Britain's diplomatic isolation in Europe. He hoped to create a collective security system based on the principles of the territorial status quo, trade agreements, neutral rights, and resolution of diplomatic disputes through mediation - armed mediation if necessary. While his domestic measures largely met with success, Pitt's foreign policy suffered from a paucity of like-minded allies, contradictions between traditional hostility to France and emergent opposition to Russian expansion, Britain's limited ability to project power on the continent, and the even more limited will of Parliament to support such interventionism. Nevertheless, Pitt's collective security goal continued to shape British strategy in the War of the First Coalition, and the same challenges continued to plague the British war effort. This led to failure in the war and left the British fighting on alone after the Treaty of Campo Formio secured peace between France and its last continental foe, Austria, on 18 October 1797.

Community-based Logistics and Supply Chain Management: Developing, Testing and Validating Conceptual Models

Description: The field of Logistics and Supply Chain Management (LSCM) suggests that transactions, collaboration, and value are important in the supply and delivery of products and services to meet the need of impoverished end-consumers. In many cases, the application of LSCM is paramount in most strategic decision-making efforts. Therefore, this research explores the applications of LSCM processes and activities within the community-based context. The methodology used to address the research questions consisted of a hybrid of mixed methods. This mixed methodology provides three essays that investigate the application and development of LSCM in the community-based context. The essays address the flow of charitable products and services through supply chains. The dissertation does not pay close attention to the first-tier suppliers’ suppliers, which is looking at the originating flow of goods and services (raw materials, manufacturing, etc.). However, the dissertation puts a focus on products and services supplied to focal organizations and how these products are then passed on to end-consumers. Essay I looks at the transaction (costs) that ensue from the supply of charitable products. Essay II analyzes a social service ecosystem and investigates how the network of organizations enable the distribution of charitable products and services. Lastly, Essay III examines the delivery of valuable services to the end-consumers, and what tools Community-Based Enterprises (CBEs) should focus on to develop and retain end-consumers in impoverished communities. The research provides conceptual models that review some fundamental LSCM achievement gaps in supplying, delivering and providing social services to end users within impoverished communities. The dissertation draws upon literature from the fields of economics, marketing, social science, and logistics and supply chain management. The dissertation uses the primary research method of unstructured and semi-structured interviews, case studies, written survey instruments and system dynamics within three studies. The studies resolve to look into the term ...

Community College Student Retention and Completion based on Financial Expenditures and Hispanic-Serving Status

Description: Despite declining community college funding being allocated increasingly on the basis of student success, U.S. community college student retention and completion rates over the past decade have either remained steady or decreased, especially for Latino students. Using descriptive statistics and multiple regression models with secondary data procured from the Integrated Postsecondary Education Data System (IPEDS), I analyzed student success rates—full time student retention and completion rates—based on community college financial allocations and Hispanic-serving institution (HSI) status. To equitably analyze community colleges in the sample (n = 909), I separated them into four groups based on institutional size as defined by the Carnegie Classification. Descriptive results indicated that instructional divisions spent an average of 43% of the college's total allocated budget—often more than three times the allocated budget of any other division. Regression results indicated that instructional expenditures had the most consistent impact on student success regardless of college size and that scholarship expenditures and academic support expenditures generally had a negative impact on student retention and completion rates. Regarding Latino student success in particular, findings indicated that the manner in which colleges allocated their funds impacted only small and medium-sized community colleges. Of the nine different types of institutional expenditures, only student services expenditures and public services expenditures had a statistically significant impact on Latino student success. Additionally regression analysis indicated that community college HSI status did not have a large impact on overall full-time student retention and completion rates but did have a significant impact on full-time Hispanic student retention and completion rates for all institution sizes. Findings of this study confirmed that HSI status does impact Latino student success in public community colleges. This finding is consistent with prior studies on the positive impact of instructional expenditures on student success rates. Further research on the specific elements within ...

A Comparative Analysis of Digital and Paper Restaurant Menus Based on Customer Perception and Nutritional Labeling

Description: The restaurant industry is a highly customer-driven field. Therefore, it is imperative that restaurateurs consider customer expectations with regard to restaurant menus. The purpose of this experimental study is to examine the effects of menu format (i.e., paper or digital) and amount of nutritional information (i.e., extensive, brief, or none) on customer perceptions of the effectiveness, perceived ease of use, and information quality of the menu. Furthermore, this research intends to test the effect of these three menu attributes on the outcomes of value and satisfaction in order to assess the competitive advantage of one format over the other. The Cognitive Appraisal and Information Processing Theories provide structure to the proposed conceptual framework and give credence to the findings. This study also fills gaps in the present research by not only ameliorating weaknesses of extant studies, but also by examining several different aspects of restaurant menus simultaneously within a single study.

A Comparative Evaluation of Functional Analytic Methods

Description: The individual functional analysis (FA) is the most widely used method to identify variables that influence the occurrence of problem behavior. Researchers often modify the FA after the analysis reveals undifferentiated responding. The interview-informed synthesized contingency analysis (IISCA) is one of the most substantial variations of the FA that builds upon the FA modifications. We evaluated the use of the two different functional analytic methods, the FA and IISCA, and the subsequent function-based treatment to reduce problem behavior for three children with autism spectrum disorder (ASD). The individual FA and the IISCA demonstrated differentiated responding for all participants. The treatment based on the results from the traditional FA was effective for all children. We discuss the implications of these findings.

A Comparative Evaluation of Outcomes between Indirect Analyses and Functional Analytic Procedures

Description: While descriptive assessment outcomes show limited correspondence with experimental analysis outcomes, they are still often used in the treatment of problem behavior. The most effective way of treating problem behavior is by manipulating its controlling variables; however, if descriptive analyses are not depicting accurate environment-behavior relations, then treatments based off of descriptive analysis results have a higher chance of failing. The current study looks to replicate and extend the literature on utility descriptive assessments by analyzing three different data analysis methods. Three children with a diagnosis of autism were exposed to two types of experimental analyses. Following experimental analyses, descriptive assessments were completed and analyzed to determine correlations between the behavior and environmental events. The results from the three investigated data analysis methods were then compared to the outcomes of the experimental analyses.

Comparison of Heterogeneity and Heterogeneity Interval Estimators in Random-Effects Meta-Analysis

Description: Meta-analyses are conducted to synthesize the quantitative results of related studies. The random-effects meta-analysis model is based on the assumption that a distribution of true effects exists in the population. This distribution is often assumed to be normal with a mean and variance. The population variance, also called heterogeneity, can be estimated numerous ways. Accurate estimation of heterogeneity is necessary as a description of the distribution and for determining weights applied in the estimation of the summary effect when using inverse-variance weighting. To evaluate a wide range of estimators, we compared 16 estimators (Bayesian and non-Bayesian) of heterogeneity with regard to bias and mean square error over conditions based on reviews of educational and psychological meta-analyses. Three simulation conditions were varied: (a) sample size per meta-analysis, (b) true heterogeneity, and (c) sample size per effect size within each meta-analysis. Confidence or highest density intervals can be calculated for heterogeneity. The heterogeneity estimators that performed best over the widest range of conditions were paired with heterogeneity interval estimators. Interval estimators were evaluated based on coverage probability, interval width, and coverage of the estimated value. The combination of the Paule Manel estimator and Q-Profile interval method is recommended when synthesizing standardized mean difference effect sizes.

Competing Models of Hegemonic Masculinity in English Civil War Memoirs by Women

Description: This thesis examines the descriptions of Royalist and Parliamentarian masculinity in English Civil War memoirs by women through a close reading of three biographical memoirs written by Margaret Cavendish, duchess of Newcastle; Lady Ann Fanshawe; and Lucy Hutchinson. Descriptions of masculinity are evaluated through the lens of Raewyn Connell's theory of hegemonic masculinity to understand the impact two competing models of masculinity had on the social and political culture of the period. The prevailing Parliamentarian hegemonic masculinity in English Civil War memoirs is traced to its origins before the English Civil War to demonstrate how hegemonic masculinity changes over time. The thesis argues that these memoirs provide evidence of two competing models of Royalist and Parliamentarian masculinities during the Civil War that date back to changes in the Puritan meaning of the phrase “man of merit”, which influenced the development of a Parliamentarian model of masculinity.

Compostable Soy-Based Polyurethane Foam with Kenaf Core Modifiers

Description: Building waste and disposable packaging are a major component in today's landfills. Most of these are structural or thermally insulative polymer foams that do not degrade over a long period of time. Currently, there is a push to replace these foams with thermoplastic or biodegradable foams that can either be recycled or composted. We propose the use of compostable soy-based polyurethane foams (PU) with kenaf core modifiers that will offer the desired properties with the ability to choose responsible end-of-life decisions. The effect of fillers is a critical parameter in investigating the thermal and mechanical properties along with its effect on biodegradability. In this work, foams with 5%, 10%, and 15% kenaf core content were created. Two manufacturing approaches were used: the free foaming used by spray techniques and the constrained expansion complementary to a mold cavity. Structure-property relations were examined using differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermal conductivity, compression values, scanning electron microscopy (SEM), x-ray micro-computed tomography (micro-CT), and automated multiunit composting system (AMCS). The results show that mechanical properties are reduced with the introduction of kenaf core reinforcement while thermal conductivity and biodegradability display a noticeable improvement. This shows that in application properties can be improved while establishing a responsible end-of-life choice.

A Comprehensive Modeling Framework for Airborne Mobility

Description: Mobility models serve as the foundation for evaluating and designing airborne networks. Due to the significant impact of mobility models on the network performance, mobility models for airborne networks (ANs) must realistically capture the attributes of ANs. In this paper, I develop a comprehensive modeling framework for ANs. The work I have done is concluded as the following three parts. First, I perform a comprehensive and comparative analysis of AN mobility models and evaluate the models based on several metrics: 1) networking performance, 2) ability to capture the mobility attributes of ANs, 3) randomness levels and 4) associated applications. Second, I develop two 3D mobility models and realistic boundary models. The mobility models follow physical laws behind aircraft maneuvering and therefore capture the characteristics of aircraft trajectories. Third, I suggest an estimation procedure to extract parameters in one of the models that I developed from real flight test data. The good match between the estimated trajectories and real flight trajectories also validate the suitability of the model. The mobility models and the estimation procedure lead to the creation of “realistic” simulation and evaluation environment for airborne networks.

Connected and Benevolent: The Positive Impact of Social Connections in Reducing Economic Concerns for Volunteering

Description: This dissertation attempts to answer how social and economic mechanisms operate in individual, community and state levels to impact volunteering. Both social processes and economic factors significantly impact the amount of volunteering. However, researchers have a tendency to explain volunteering only by one of these factors. As both theories are equally important in explaining volunteerism, the development of a coherent theory is necessary to combine economic and social theories. This dissertation suggested that, when evaluated together, the influences of the economic factors on volunteering diminish as individuals get more connected with the other members of the society. The three-level analysis of the volunteering largely supports the primary hypothesis of the dissertation that economic concerns for volunteering are crowded out when individuals or the society is highly connected. This finding can help practitioners design better strategies to enhance volunteering such as creating opportunities for the members of the society to interact with each other.

Constructing Taiwan: Taiwanese Literature and National Identity

Description: In this work, I trace and reconstruct Taiwan's nation-formation as it is reflected in literary texts produced primarily during the country's two periods of colonial rule, Japanese (1895-1945) and Kuomintang or Chinese Nationalist Party (KMT) (1945-1987). One of my central arguments is that the idea of a Taiwanese nation has historically emerged from the interstices of several official and formal nationalisms: Japanese, Chinese, and later Taiwanese. In the following chapters, I argue that the concepts of Taiwan and Taiwanese have been formed and enriched over time in response to the pressures exerted by the state's, colonial or otherwise, pedagogical nation-building discourses. It is through an engagement with these various discourses that the idea of a Taiwanese nation has come to be gradually defined, negotiated, and reinvented by Taiwanese intellectuals of various ethnic backgrounds. I, therefore, focus on authors whose works actively respond to and engage with the state's official nationalism. Following Homi Bhabha's explication in his famous essay "DissemiNation," the basic premise of this dissertation is that the nation, as a narrated space, is not simply shaped by the homogenizing and historicist discourse of nationalism but is realized through people's diverse lived experience. Thus, in reading Taiwanese literature, it is my intention to locate the scraps, patches, and rags of daily life represented in a select number of texts that signal the repeating and reproductive energy of a national life and culture.

The Contribution of Mira Behn and Sarala Behn to Social and Environmental Transformation in the Indian State of Uttarakhand

Description: The influence of Mohandas K. Gandhi on social and environmental movements in post-colonial India has been widely acknowledged. Yet, the contributions of two European associates of Gandhi, Madeleine Slade and Catherine Mary Heilemann, better known in India as Mira Behn and Sarala Behn, have not received the due attention of the academic community. This dissertation is an examination of the philosophy and social activism of Mira Behn and Sarala Behn and their roles in the evolution of Gandhian philosophy of socioeconomic reconstruction and environmental conservation in the present Indian state of Uttarakhand. Instead of just being acolytes of Gandhi, I argue that these women developed ideas and practices that drew upon from an extensive intellectual terrain that cannot be limited to Gandhi’s work. I delineate the directions in which Gandhian thought and experiments in rural development work evolved through the lives, activism, and written contributions of these two women. Particularly, I examine their influence on social and environmental movements, such as the Chipko and the Anti-Tehri Dam movements, and their roles in promoting grassroots social development and environmental sustainability in the mountain communities of Uttarakhand. Mira Behn and Sarala Behn’s integrative philosophical worldviews present epistemological, sociopolitical, ethical, and metaphysical principles and practices that have local and global significance for understanding interfaith dialog, social justice, and environmental sustainability and thus constitute a useful contribution to the theory and practice of human emancipation in our times.

Control and Automation of a Heat Shrink Tubing Process

Description: Heat shrink tubing is used to insulate wire conductors, protect wires, and to create cable entry seals in wire harnessing industries. Performing this sensitive process manually is time consuming, the results are strongly dependent on the operator’s expertise, and the process presents safety concerns. Alternatively, automating the process minimizes the operators’ direct interaction, decreases the production cost over the long term, and improves quantitative and qualitative production indicators dramatically. This thesis introduces the automation of a heat shrink tubing prototype machine that benefits the wire harnessing industry. The prototype consists of an instrumented heat chamber on a linear positioning system, and is fitted with two heat guns. The chamber design allows for the directing of hot air from the heat guns onto the wire harness uniformly through radially-distributed channels. The linear positioning system is designed to move the heat chamber along the wire harness as the proper shrinkage temperature level is reached. Heat exposure time as a major factor in the heat shrink tubing process can be governed by controlling the linear speed of the heat chamber. A control unit manages the actuator position continuously by measuring the chamber’s speed and temperature. A model-based design approach is followed to design and test the controller, and MATLAB/Simulink is used as the simulation environment. A programmable logic controller is selected as the controller implementation platform. The control unit performance is examined and its responses follow the simulation results with adequate accuracy.

Cooperative Strategy and Sources of Knowledge Integration Capability and Innovation: A Relational View

Description: Faced with the challenges to addressing the novelties of the changing business environments (e.g., new customer requirement, changes in customers taste and preferences, the introduction of new products or services by competitors), organizations seek to build collaboration among their employees who possess complementary knowledge. Integrating complementary knowledge enhances employees' ability to address environmental challenges and foster innovation. Despite the importance of knowledge integration for innovation, integration of such knowledge becomes difficult when employees lack a shared understanding of knowledge, and when the knowledge is newly generated. Because new knowledge is tacit in nature and highly personal to a particular individual, it is difficult to articulate, making knowledge integration (KI) an arduous task. Lack of shared understanding, the presence of new knowledge, and lack of common interests in employees creates three types of knowledge boundaries – syntactic (information processing) boundaries, semantic (interpretive) boundaries, and pragmatic (political) boundaries. The presence of knowledge boundaries makes it difficult for employees to share and access their knowledge with each other. To overcome the challenges related to the knowledge boundaries, employees use boundary-spanning objects, which are common lexicons, common meaning, and common interests, to share and access their knowledge across the boundaries. Although prior studies have emphasized the importance of knowledge integration of various knowledge sources for innovations, examinations of what enhances KI capability of employees for organizational innovation remain limited. In addition, apart from Carlile, (2004) and Franco (2013), which are both case studies, other studies that examine the role of boundary spanning objects for knowledge integration are missing. The knowledge management literature also fails to measures (the success of common lexicons, common meaning, and common interests for achieving KI capability) boundary spanning objects. Therefore, in this study, new measurement items of boundary spanning objects and novelty are developed to test the hypotheses. A survey-based ...

Corporeal Judgment in Shakespeare's Plays

Description: In this dissertation, I examine the complex role that the body played in early modern constructions of judgment. Moving away from an overreliance on anti-theatrical texts as the authority on the body in Shakespeare's plays, my project intervenes in the field Shakespearean studies by widening the lens through which scholars view the body's role in the early modern theater. Through readings of four plays—Richard II, Hamlet, King Lear, and The Winter's Tale—I demonstrate that Shakespeare uses a wide range of ideas about the human body from religious, philosophical, medical, and cultural spheres of thought to challenge Puritan accusations that the public theater audience is incapable of rational judgment. The first chapter outlines the parameters of the project. In Chapter 2, I argue that Richard II draws parallels between the theatrical community and the community created through the sacramental experiences of baptism and communion to show that bodies play a crucial role in establishing common experience and providing an avenue for judgment. In Chapter 3, I argue that Shakespeare establishes correspondences between bodily and social collaboration to show how both are needed for the memory-making project of the theater. In the next chapter, I show how Shakespeare appropriates what early moderns perceived of as the natural vulnerability in English bodies to suggest the passionate responses associated with impressionability can actually be sources of productive judgment and self-edification. I argue the storm models this passionate judgment, providing a guide for audience behavior. In Chapter 5, I argue that the memories created by and within the women in The Winter's Tale evoke the tradition of housewifery and emphasize the female role in preservation. Female characters stand in for hidden female contributors to the theater and expose societal blindness to women's work. Through each of these chapters, I argue that Shakespeare's plays emphasize the ...

"Counting Out The Harvest"

Description: "Counting Out The Harvest" is a collection of poems exploring intimate encounters. The poems reflect on encounters with memories, family, and the natural and cosmic worlds. In one of the poems, "Red-Throated Anole," the speaker works desperately to save a small dying lizard. In "Ice Storm, Post-Divorce," the speaker attempts to decipher a cluster of ladybugs taking refuge in her room. In the title poem, a couple wonders patiently if their crop will eventually grow. In each of these poems there is a present longing for the construction of a meaningful identity by means of the encounter, but the intersection between speaker and world falls short of satisfaction, whether the faultiness lies in the body's inability to find full sustenance, or in the ever-changing fluidity of memory to find stability. But the poems progress from pressing against this difficulty toward finding a contented resignation to the world's cyclical order. The final line of the manuscript, "disrobe a layer to begin again," indicates an arrival at satisfaction, which is found ultimately in continuation.

Customers' Attitudes toward Mobile Banking Applications in Saudi Arabia

Description: Mobile banking services have changed the design and delivery of financial services and the whole banking sector. Financial service companies employ mobile banking applications as new alternative channels to increase customers' convenience and to reduce costs and maintain profitability. The primary focus of this study was to explore the Saudi bank customers' perceptions about the adoption of mobile banking applications and to test the relationships between the factors that influence mobile banking adoption as independent variables and the action to adopt them as the dependent variable. Saudi customers' perceptions were tested based on the extended versions of IDT, TAM and other diffusion of innovation theories and frameworks to generate a model of constructs that can be used to study the use and the adoption of mobile technology by users. Koenig-Lewis, Palmer, & Moll's (2010) model was used to test its constructs of (1) perceived usefulness, (2) perceived ease of use, (3) perceived compatibility, (4) perceived credibility, (5) perceived trust, (6) perceived risk, and (7) perceived cost, and these were the independent variables in current study. This study revealed a high level of adoption that 82.7% of Saudis had adopted mobile banking applications. Also, the findings of this study identified a statistically significant relationship between all of demographic differences: gender, education level, monthly income, and profession and mobile banking services among adopters and non-adopters. Seven attributes relating to the adoption of mobile banking applications were evaluated in this study to assess which variables affected Saudi banks customers in their adoption of mobile banking services. The findings indicated that the attributes that significantly affected the adoption of mobile banking applications among Saudis were perceived trust, perceived cost, and perceived risk. These three predictors, as a result, explained more than 60% of variance in intention to adopt mobile banking technology in Saudi Arabia. ...

Daily-collected Sleep Diaries Compared to Weekly-collected Sleep Diaries Via Actigraph Concordance

Description: Both sleep diaries and actigraphy have been recommended to assess sleep in research and clinical settings. Investigators have traditionally used sleep diaries that were completed daily by participants and collected weekly but have recently begun using sleep diaries that are both completed and collected daily. No research had previously assessed the agreement between daily-collected sleep diaries and actigraph data over one week. Undergraduate students were randomly assigned to use daily- or weekly-collected sleep diaries. Sleep parameters obtained from these measures were compared to each other via concordance with concurrent actigraph data. It was hypothesized that daily-collected sleep diaries would have greater concordance with actigraphy than weekly-collected sleep diaries. Results indicated that daily-collected sleep diaries provided more reliable data than weekly-collected sleep diaries, but the differences were not statistically significant. Additional aims examined self-reported sleep diary adherence, the participation day number, and day of the week. There were trends for the Daily group to have better adherence. Overall concordance did not change based on the day number or day of the week. Both sleep diaries yield comparable sleep parameter data, suggesting that clinicians and researchers can use either method to estimate sleep parameters.

Data Compression Using a Multi-residue System (Mrs)

Description: This work presents a novel technique for data compression based on multi-residue number systems. The basic theorem is that an under-determined system of congruences could be solved to accomplish data compression for a signal satisfying continuity of its information content and bounded in peak-to -peak amplitude by the product of relatively prime moduli,. This thesis investigates this property and presents quantitative results along with MATLAB codes. Chapter 1 is introductory in nature and Chapter 2 deals in more detail with the basic theorem. Chapter 3 explicitly mentions the assumptions made and chapter 4 shows alternative solutions to the Chinese remainder theorem. Chapter 5 explains the experiments in detail whose results are mentioned in chapter 6. Chapter 7 concludes with a summary and suggestions for future work.
