Signal To Noise Ratio Estimation Using The Expectation Maximization Algorithm, Ahmed Almradi

Theses

Signal to Noise Ratio (SNR) estimation when the transmitted symbols are unknown is a common problem in many communication systems, especially those which require an accurate SNR estimation. For instance, modern wireless communication systems usually require accurate estimate of SNR without knowledge of the transmitted symbols. In addition, SNR estimation is required in order to perform efficient signal detection, power control, and adaptive modulation In this study, Non data Aided (NDA) SNR estimation for Binary Phase Shift Keying (PBSK) and Quadrature Phase Shift Keying (QPSK) using the Expectation Maximization (EM) algorithm is developed. The assumption here is that the received …

Creative Differences: Teaching Creativity Across The Disciplines, Elizabeth Marquis, Susan Vajoczki

International Journal for the Scholarship of Teaching & Learning

Several authors have suggested that educational institutions have a responsibility to foster creativity in their students. Yet, research has shown that creativity is a variable concept that can mean different things in different fields and contexts (Kaufman & Baer, 2005). As a result, generic pedagogical techniques for developing creativity may not be equally appropriate across domains.

In light of these factors, this pilot study explored (via an electronic survey of instructors) the ways in which creativity is defined and taught across McMaster University’s six faculties. Results suggested areas of both commonality and difference across disciplines in terms of academics’ understandings …

[Introduction To] Leadership And Global Justice, Douglas A. Hicks, Thad Williamson

Bookshelf

What does global justice look like, and how can leadership help get us there? The contributors to Leadership and Global Justice confront the conceptual and practical challenges associated with pursuing justice beyond national boundaries. Essays analyze the roles and responsibilities of institutions - states, corporations, international financial institutions, UN bodies, nongovernmental organizations - in making collaborative progress towards international justice. They explore justice in various spheres: citizenship, the marketplace, health, education, and the environment. And they provide creative and constructive moral approaches for evaluating and promoting global justice, including human rights, capabilities, and solidarity of people across boundaries.

Institutional Factors Contributing To The Under-Representation Of African American Women In Higher Education: Perceptions Of Women In Leadership Positions, Kimberly Ann Robinson

College of Graduate Studies: Theses & Dissertations

he purpose of this basic qualitative study was to examine the lived experiences of African American women who have obtained senior leadership positions in Predominantly White Higher Education Institutions. Data were collected through open-ended, phenomenological-oriented interviews with 12 African American women holding senior level positions in both academic and student affairs in the north and southeast parts of the United States. This study focused on the perceived institutional barriers that have contributed to the under-representation of African American women in higher education senior administration and strategies that were used to overcome perceived barriers. Critical Race Theory was used as a …

Xrf And The Corrosion Environment At Camp Lawton: A Comprehensive Study Of The Archeological Microenvironment Of A Civil War Prison Camp, Amanda L. Morrow

College of Graduate Studies: Theses & Dissertations

Author's abstract: Handheld X Ray Fluorescence (XRF) technology is a new and emerging method in the field of archeology. This thesis discusses the results of XRF comparative analysis and comparative chemical analysis between a given ferrous metallic artifact's corrosion environment (the surrounding soil matrix) and the subsequent corrosion products formed on the artifact. The hypothesis is that the data will demonstrate a chemical correlation between the two. Iron and chlorine are the two major elements discussed in the study. The artifacts in the sample set have been collected from Camp Lawton (9JS1), a Confederate Prison for Union Soldiers located in …

Motivation, Need Support And Need Satisfaction In Youth Soccer Players, Erica Lippitt

College of Graduate Studies: Theses & Dissertations

Author's abstract: Physical activity levels and obesity rates vary greatly across ethnic groups in the United States (CDC, 2011). One popular way to increase physical activity levels in youth is through youth sport participation, which may be influenced by athlete motivation. Numerous studies have determined motivation levels in youth sport participants, but very little done in comparing levels across different ethnic groups. Identifying differences in motivation levels based on ethnicity can allow coaches and sport administrators to adjust practices and program setups to increase participation and meet needs of player competence. The purpose of the study was to determine if …

Analyzing Levels Of Feedback Delivered By Cooperating Teachers And Supervisors In A Teacher Internship: A Case Study, James Badger

Georgia Educational Researcher

This research analyzed the feedback delivered by cooperating teachers and university supervisors in an internship, and reports how student teachers perceived the feedback they received during debriefing sessions with their mentors. Hattie and Timperley’s (2007) framework for conceptualizing effective feedback was used to analyze cooperating teachers’ and field supervisor’ assessment of the student teachers’ classroom instruction. Findings from two surveys, documents, and interviews revealed a preponderance of feedback that was devoted to instruction and classroom management with a relative paucity of feedback dedicated to the processing of instruction, consideration of student learning, and development of self-reflection in the student teachers. …

A Quantitative Content Analysis Of Mercer University Theses, Justus J. Randolph, Lura S. Gaiek, Torian A. White, Lisa A. Slappey, Andrea Chastain, Rose Prejean-Harris, Cole Hansard

Georgia Educational Researcher

Quantitative content analysis of a body of research not only helps budding researchers understand the culture, language, and expectations of scholarship, it helps identify deficiencies and inform policy and practice. Because of these benefits, an analysis of a census of 980 Mercer University M.Ed., Ed.S., and doctoral theses was conducted. Each thesis was coded on 10 variables. The descriptive characteristics of the theses, the predictors of the length of the theses, and the predictors of the type of research method used were investigated. The main results were that: (a) the vast majority of thesis authors was female, (b) the number …

Imbalance Challenge Of Enacting Information Privacy Safeguards In Healthcare: A Grounded Theory Approach, Rachida Parks, Heng Xu, Chao-Hsien Chu

Research Collection School Of Computing and Information Systems

Healthcare organizations face significant challenges in designing and implementing the appropriate safeguards to mitigate information privacy threats. While many studies examined various technical and behavioral safeguards to protect the confidentiality and privacy of patient information, very little is known about the actual outcomes and implications of the privacy practices in which organizations engage. There is little research theoretically explaining the outcomes of enacting privacy safeguards and subsequent effects on privacy compliance. This paper reports the results of a grounded theory study investigating the intended consequences (positive impacts) and unintended (negative impacts) consequences of enacting privacy safeguards in healthcare organizations. An …

The Politics Of Human Development In India And China: It Pays To Invest In Women And Children, Devin K. Joshi

Research Collection School of Social Sciences

This article explores the attainments of China and India on measures of basic human development as ingredients of a long-term economic development strategy. It proposes that major differences in ideology and state capacity explain in part why India has fallen behind China. The analysis suggests that these relatively hidden political factors play an important role in transforming and advancing human development not only within India and China but also in other developing and emerging economies. The findings also support the notion that public investments in the capabilities of women and children have significant social and economic payoffs in both the …

Why Open Borders, Chandran Kukathas

Research Collection School of Social Sciences

The present contribution offers a defence of open borders. It presents a critique of the idea that the state has a justified claim to regulate themovement of people because they reflect the collective endeavours of the members of the state to pursue a shared project of self-rule or self-determination. Itargues that this view rests on an indefensible understanding of the nature of thestate, which should be viewed less as a collective endeavour than as a productof conflicts among political elites. There is a strong prima facie case for freemovement that suggests there should be a presumption in favour of open …

A Household-Level Decomposition Of The White-Black Homeownership Gap, Eric Fesselmeyer, Kien T. Le, Kiat Ying Seah

Research Collection College of Integrative Studies

This paper uses a semiparametric homeownership model to estimate and to decompose the household-level white-black homeownership gap into an endowment component and a residual component across the distribution of homeownership rates. We find that the racial gap differs across homeownership rates and that studies that examine the gap only at the mean may be misleading. We also find that although household characteristics explain the homeownership gap for most households, there is a substantial portion of the gap that remains unexplained for households with a very low propensity to own homes. A comparison of the estimates from the semiparametric model and …

Beyond Minority Report: Pre-Crime, Pre-Punishment And Pre-Desert, John N. Williams

Research Collection School of Social Sciences

Utilitarian ethics are apparently incommensurable with other ethical perspectives. Faced with a choice between maximizing general benefit to society and committing an act of injustice, those of us who reject utility in favor of justice are powerless to change the viewpoint of someone who rejects justice in favor of utility. Since there are no higher ethical principles that overarch both principles of utility and principles of justice, both sides must run out of reasons when deciding which principles should be put first. But the unreasoned decision is ineluctable, because there are possible cases in which the principles conflict.1 This kind …

War, Military Service, And Union Formation In Northern Vietnam, Bussarawan Teerawichitchainan

Research Collection School of Social Sciences

As wars exert increasing force on global affairs, there is greater demand for understanding the international diversity of family experiences with conflicts. This study examines the relationship between military participation during the Vietnam War (1965-1975) and first-marriage timing among northern Vietnamese men and women. Based on the Vietnam Longitudinal Survey and its recent followup, this paper describes cohort variations in the likelihood and timing of first marriage during pre-war, wartime, and post-war years and addresses the effects of veteran status, combat exposure, duration and timing of service. We find war did not decrease marriage likelihood among men but caused significant …

Correlates Of Homeless Episodes Among Indigenous People, Les B. Whitbeck, Devan M. Crawford, Kelley J. Sittner Hartshorn

Department of Sociology: Faculty Publications

This study reports the correlates of homeless episodes among 873 Indigenous adults who are part of an ongoing longitudinal study on four reservations in the Northern Midwest and four Canadian First Nation reserves. Descriptive analyses depict differences between those who have and have not experienced an episode of homelessness in their lifetimes. Multivariate analyses assess factors associated with a history of homeless episodes at the time of their first interview. Results show that individuals with a history of homeless episodes had significantly more individual and family health, mental health, and substance abuse problems. Periods of homelessness also were associated with …

Factors Associated With Growth In Daily Smoking Among Indigenous Adolescents, Les B. Whitbeck, Kelley J. Sittner Hartshorn, Julia Mcquillan, Devan M. Crawford

Department of Sociology: Faculty Publications

North American Indigenous adolescents smoke earlier, smoke more, and are more likely to become regular smokers as adults than youth from any other ethnic group yet we know very little about their early smoking trajectories. We use multilevel growth modeling across five waves of data from Indigenous adolescents (aged 10 to 13 years at Wave 1) to investigate factors associated with becoming a daily smoker. Several factors, including number of peers who smoked at Wave 1 and meeting diagnostic criteria for major depressive episode and conduct disorder were associated with early daily smoking. Only age and increases in the number …

Advanced Seminar – Interviewer-Respondent Interaction: Survey Research & Methodology Special Topics 898, Spring 2012, Robert Belli

Department of Sociology: Faculty Publications

This course will explore the theory and observations that underlie the attempt of survey methodologists to understand the nature of interviewer-respondent interactions and their impact on data quality. This exploration will entail the examination of different interviewing methods and different methods to observe and analyze the verbal behavioral streams that occur between interviewers and respondents. In addition, analytic approaches that seek to understand the impact of verbal behaviors on data quality will be considered.

The ‘Friendship Dynamics Of Religion,’ Or The ‘Religious Dynamics Of Friendship’? A Social Network Analysis Of Adolescents Who Attend Small Schools, Jacob Cheadle, Philip Schwadel

Department of Sociology: Faculty Publications

Longitudinal social network data on adolescents in seven schools are analyzed to reach a new understanding about how the personal and interpersonal social dimensions of adolescent religion intertwine together in small school settings. We primarily address two issues relevant to the sociology of religion and sociology in general: (1) social selection as a source of religious homophily and (2) friend socialization of religion. Analysis results are consistent with Collins’ interaction ritual chain theory, which stresses the social dimensions of religion, since network–religion autocorrelations are relatively substantial in magnitude and both selection and socialization mechanisms play key roles in generating them. …
