Image Quality Analysis Using Glcm, Dhanashree Gadkari Jan 2004

Image Quality Analysis Using Glcm, Dhanashree Gadkari

Electronic Theses and Dissertations

Gray level co-occurrence matrix has proven to be a powerful basis for use in texture classification. Various textural parameters calculated from the gray level co-occurrence matrix help understand the details about the overall image content. The aim of this research is to investigate the use of the gray level co-occurrence matrix technique as an absolute image quality metric. The underlying hypothesis is that image quality can be determined by a comparative process in which a sequence of images is compared to each other to determine the point of diminishing returns. An attempt is made to study whether the curve of …

Security Of A Small State: Case Of Kuwait, Shawn Adelwerth Jan 2004

Security Of A Small State: Case Of Kuwait, Shawn Adelwerth

HIM 1990-2015

Kuwait is a small country in terms of size and military might, however, it has an abundance of oil wealth. Kuwaiti rulers have often met their domestic and international security challenges with buying off the problems. This type of policy continued until late 1989, when the tension between Iraq and Kuwait reached a new height. The turning point for Kuwait security was 2 August 1990, when Iraqi military finally invaded Kuwait requested the military power of the United States. This began a new era in the United States-Kuwait relationship. Since Iraqi forces were discharged from this small Gulf State, Kuwait …

A Holistic Model Of The Interplay Of Parent-Adolescent Interaction Varialbes: Outcomes As A Result Of Conflictual Processes, Cliff Blake Mckinney Jan 2004

A Holistic Model Of The Interplay Of Parent-Adolescent Interaction Varialbes: Outcomes As A Result Of Conflictual Processes, Cliff Blake Mckinney

Electronic Theses and Dissertations

Many variables have been analyzed in order to understand parent-adolescent interactions and outcomes for adolescents. These variables must be integrated into a model that demonstrates the holistic interplay of parent-adolescent interaction variables so that a more comprehensive understanding of parent-adolescent interactions is achieved. Variables included in the model proposed here were parenting, family environment, expectations, conflict, and outcomes. Parenting, family environment, and conflict were associated with outcomes for adolescents. When the variables were analyzed simultaneously with structural equation modeling, however, the relationship of parenting and adolescent outcomes was mediated wholly for male-father, male-mother, and female-father relationships but remained significant for …

Improving Metacomprehension And Learning Through Graduated Concept Mod, Eleni Kring Jan 2004

Improving Metacomprehension And Learning Through Graduated Concept Mod, Eleni Kring

Electronic Theses and Dissertations

Mental model development, deeper levels of information processing, and elaboration are critical to learning. More so, individuals' metacomprehension accuracy is integral to making improvements to their knowledge base. In other words, without an accurate perception of their knowledge on a topic, learners may not know that knowledge gaps or misperceptions exist and, thus, would be less likely to correct them. Therefore, this study offered a dual-process approach that aimed at enhancing metacomprehension. One path aimed at advancing knowledge structure development and, thus, mental model development. The other focused on promoting a deeper level of information processing through processes like elaboration. …

Transforming Learning Into A Constructive Cognitive And Metacognitive, Haydee Cuevas Jan 2004

Transforming Learning Into A Constructive Cognitive And Metacognitive, Haydee Cuevas

Electronic Theses and Dissertations

This study explored the effectiveness of embedding a guided, learner-generated instructional strategy (query method), designed to support learners' cognitive and metacognitive processes, within the context of a computer-based complex task training environment (i.e., principles of flight in the aviation domain). The queries were presented as "stop and think" exercises in an open-ended question format that asked learners to generate either simple (low-level elaboration) or complex (high-level elaboration) sentences from a list of key training concepts. Results consistently highlighted the benefit of presenting participants with low-level elaboration queries, as compared to the no-query or high-level elaboration queries. In terms of post-training …

The Effects Of Differential Item Functioning On Predictive Bias, Damon Bryant Jan 2004

The Effects Of Differential Item Functioning On Predictive Bias, Damon Bryant

Electronic Theses and Dissertations

The purpose of this research was to investigate the relation between measurement bias at the item level (differential item functioning, dif) and predictive bias at the test score level. Dif was defined as a difference in the probability of getting a test item correct for examinees with the same ability but from different subgroups. Predictive bias was defined as a difference in subgroup regression intercepts and/or slopes in predicting a criterion. Data were simulated by computer. Two hypothetical subgroups (a reference group and a focal group) were used. The predictor was a composite score on a dimensionally complex test with …

Effects Of Voluntary Control On Performance Response Under Stress., Christina Shawn Morris Jan 2004

Effects Of Voluntary Control On Performance Response Under Stress., Christina Shawn Morris

Electronic Theses and Dissertations

Recent stressful environments within military and non-military domains are producing a new challenge for the lab-based study of stress on task performance, one that requires knowledge of underlying cognitive-motivational and goal orientation factors. Results of recent stress on task performance research traditionally employ metaphorical explanations (i.e., resource theory) in order to rapidly apply stimulus-response outcomes to the real world counterparts. This dissertation provides an alternative perspective about these metaphorical, or black box, interpretations and reveals how they may be confounded with respect to the intended real world counterpart. To examine how voluntary human control can influence traditional stress/no-stress research findings, …

An Investigation Into Providing Feedback To Users Of Decision Support, James Pharmer Jan 2004

An Investigation Into Providing Feedback To Users Of Decision Support, James Pharmer

Electronic Theses and Dissertations

Research in several domains has shown that the implementation of computerized decision support aids is often associated with issues of human-automation interaction, which can have disastrous consequences. One often-cited reason for these issues is the poor quality of the feedback that is provided to the operators through these tools. The objective of the proposed investigation is to examine how providing feedback through a decision support tool affects operator knowledge and performance in the context of a fault management task for naval gunfire support. A one-way between-groups comparison was made to investigate differences between providing decision support feedback (logic trace, mission …

The Effects Of Stimulus Motion On Contrast Sensitivity: Dynamic Sensi, Merrill Zavod Jan 2004

The Effects Of Stimulus Motion On Contrast Sensitivity: Dynamic Sensi, Merrill Zavod

Electronic Theses and Dissertations

Static Visual Acuity (SVA) has been called into question for some time as a measure of overall visual system function and as a predictor of performance on real-life tasks requiring vision (i.e., operating an automobile). Specifically, it has been pointed out that the targets employed in most SVA testing (high contrast, stationary letters) are an insufficient analog to actual targets encountered in everyday activities, which are often in motion and/or of less-than-perfect contrast. In addition, the size-threshold methodology typically used to measure SVA is incongruent with current theories of a multi-channel visual system. Dynamic Visual Acuity (DVA) and Contrast Sensitivity …

Gun Ownership Trends In The United States, 1973-2000, Jason Michael Ruckert Jan 2004

Gun Ownership Trends In The United States, 1973-2000, Jason Michael Ruckert

Electronic Theses and Dissertations

In the last half century, gun ownership has been one of the most hotly debated topics in the United States. The right to bear arms was written into the U. S. Constitution and into the hearts and minds of its citizens. During the last half century, however, numerous gun control laws have been enacted at Federal, state and local levels, and it can be argued (plausibly or not) that part of the legislative intent has been to decrease the number of gun owning households in the United States. For many decades, this number hovered at one half of all households …

Population Churn: The Migration Flow Of Florida, Marguerite Cashen Jan 2004

Population Churn: The Migration Flow Of Florida, Marguerite Cashen

Electronic Theses and Dissertations

Recent research has focused attention on the concerns of migration in and out of Florida and within the counties themselves. In 1949, Cape Canaveral was established and the boom was on. The character of the state dramatically transformed after 1965, when plans were announced to convert twenty-seven thousand acres of swampland into Walt Disney World. Since then, Orlando's evolution is divided into two eras: before and after Walt Disney World. Orlando has changed from a quiet town whose function was to service the surrounding citrus growing regions in a sparsely populated Orange County to a booming metropolis. Has the growth …

Explaining Churn: Mass Society, Social Capital, & Community Churn, Delores Edelen Jan 2004

Explaining Churn: Mass Society, Social Capital, & Community Churn, Delores Edelen

Electronic Theses and Dissertations

Population churn--the population turnover experienced by a community--can have differential effects on a community. Mass society theory suggests that because the churn rate experienced by communities can contribute to their uprooting, fragmentation, and isolation, churn is a potent threat to the stability of our modern day communities. Social capital theory, to the contrary, suggests otherwise. Social capital theory suggests that churn can have positive effects on communities by bringing new migrants with valuable human capital skills and experiences to communities. These migrants bring to their new communities the potential for creating new jobs, spurring economic development, and for initiating housing …

Aggression In Lesbian And Bisexual Relationships, Jennifer Rae Parham Jan 2004

Aggression In Lesbian And Bisexual Relationships, Jennifer Rae Parham

Electronic Theses and Dissertations

For years, researchers, clinicians, and those working with victims/survivors of domestic abuse have overlooked the issue of same-sex partner aggression among lesbians and bisexual women. Through in-depth interviews with 19 women who identify themselves as either lesbian or bisexual, information was documented in this study demonstrating the severity of issues of power and control among some same-sex partners, as well as some if the dynamics that are unique to same-sex abusive relationships. Patterns of abuse within same-sex relationships often mirror those that are so commonly associated with partner aggression among heterosexual couples, and therefore demonstrate not only the need for …

Exposure Matters: Examining The Physical And Psychological Health Impacts Of Toxic Contamination Using Gis And Survey Data, Christine A. Bevc Jan 2004

Exposure Matters: Examining The Physical And Psychological Health Impacts Of Toxic Contamination Using Gis And Survey Data, Christine A. Bevc

Electronic Theses and Dissertations

In the late 1970s and early 1980s, the grassroots environmental movement brought national attention to the issues related to inequities in environmental quality. Previous research addressing these environmental inequities has progressively increased and advanced methodologically. However, the arguments and focus have been primarily limited to examining the socio-demographics in an ongoing debate of race and class. This thesis extends past the methodological stalemate focusing on the application of Geographic Information Systems (GIS) using survey data in an environmental justice case study of a community in south Florida. This approach examines the social, health and environmental impacts of a Superfund site …

The Lack Of Diversity On The Bench In Florida's State Courts, Verlinda Wells Jan 2004

The Lack Of Diversity On The Bench In Florida's State Courts, Verlinda Wells

Electronic Theses and Dissertations

Diversity in the judiciary is essential to ensure impartiality, public confidence, and the perception that all members of society are represented on the bench. Minorities and women are significantly underrepresented as judges in Florida in proportion to their numbers in the general population. Because we live in an increasingly global world, diversity is best described when people of different races, colors, ethnicity and genders work to develop a mutual respect for each other. It was important to use diversity in this research because it required recognition, understanding, and acceptance of the special contribution that each member of a group can …

George Liska's Realist Alliance Theory, And The Transformation Of Nato, Sergey Kireyev Jan 2004

George Liska's Realist Alliance Theory, And The Transformation Of Nato, Sergey Kireyev

Electronic Theses and Dissertations

In many aspects, political theory forms a subjective structure of this abstract science. Perhaps, it is due to the fact that unlike natural sciences or mathematics, social sciences often lack the privilege of testing the theories in absolute and unadulterated conditions. Nonetheless, such nature of the science allows for a certain degree of flexibility, when applying political theories to real-world phenomena. Alliances and coalitions in international relations form the backbone of the theory, concerning IR scholars with two main questions: Why do alliances and coalitions form? And, what keeps alliances and coalitions together? As the core of my research, I …

Facade Democracy: Democratic Transition In Kazakhstan And Uzbekistan, Robin Nicole Merritt Jan 2004

Facade Democracy: Democratic Transition In Kazakhstan And Uzbekistan, Robin Nicole Merritt

Electronic Theses and Dissertations

This thesis explores the reasons behind the stagnation in the transition to democracy in Kazakhstan and Uzbekistan. According to their constitutions, Kazakhstan and Uzbekistan are democracies. In actuality, however, there is little evidence to support that these are democratic systems. These states' post-Soviet constitutions outline them as democracies - yet they lack a free press; freedom of association is suppressed; religious freedom is limited; and free speech is constrained as well. While these two countries hold popular elections, much of their electoral processes are under the control of the executive branch of government - calling into question whether or not …

The New Man And The New Lad: Hegemonic Masculinities In Men's Lifestyle Magazines, Ashley Michelle Elmore Jan 2004

The New Man And The New Lad: Hegemonic Masculinities In Men's Lifestyle Magazines, Ashley Michelle Elmore

Electronic Theses and Dissertations

Men are bombarded with contradictory masculine imagery in the media. The perfect man must be aggressive but not violent, sensitive but not emotional, healthy, active and smart without being an idealist, overachiever or too bookish. Heterocentric male focused lifestyle magazines rival women’s magazines in number and availability. Some men look to these images as a tool by which to gauge their masculinity and learn their social role performance. This inquiry includes a content analysis of four major men's lifestyle magazines over a 12-month period in which four new masculinities: certitude, irony, new sexism and double voicing were critiqued. Elements of …

Tractor-Trailer Simulation And The Assessment Of Training Scenarios For City-Driving: Skill Building In The Area Of Left And Right Turns, James Whitmire

Electronic Theses and Dissertations

A simulated inner-city training scenario was found to increase skills in the area of turning when compared with a simulated off-track training scenario. To answer this question, two groups of ten participants (5 women and 5 men) were tested using three scripted scenarios focusing on left and right turns. The first training scenario (control group) is an off-track training scenario, which consists of a large asphalt lot and the use of orange cones; the second training scenario (experimental group) is an inner-city training scenario without the presence of vehicular traffic; and the third scenario (test scenario) is an inner-city scenario …

The Internet And The American Political System, Noah David, Gaar Jan 2004

The Internet And The American Political System, Noah David, Gaar

Electronic Theses and Dissertations

The past eight years have seen a great increase in Internet usage in American culture and politics. It would seem that, in our digital age, the Internet has exercised strong effects on political behavior and even on legislators. This thesis explores the variety and intensity of these effects, finding them to be substantial and growing, although not yet robust. The main influences the net has exerted on American politics take place predominantly within two areas: political campaigns and online political interest groups. Activists are certainly using the Internet for political causes, but this sort of Internet usage is really just …

Ownership Diversity Within The Media Industry: Trends And Current Conditions, Thomas E. Vizcarrondo Jan 2004

Ownership Diversity Within The Media Industry: Trends And Current Conditions, Thomas E. Vizcarrondo

Electronic Theses and Dissertations

This study seeks to determine if media ownership diversity remains at levels widely considered to be competitive and acceptable, despite consolidation within the media industry. The research augments the many studies analyzing programming diversity within the U. S. media industry. Rather than analyzing programming content, this study addresses ownership diversity by examining the diversity of media ownership within the context U. S. model, considered to be more of a decentralized, market-driven media industry when compared to other countries such as the United Kingdom or Canada. To measure diversity, the HerfindahlHirschman Index (HHI)—a measure of economic diversity widely used by economists …

Explaining Partisan Change Among Catholics In The American Electorate, Christopher Vincent, Muro Jan 2004

Explaining Partisan Change Among Catholics In The American Electorate, Christopher Vincent, Muro

Electronic Theses and Dissertations

This thesis examines data from the National Election Studies in order to assess the significant determinants of the political behavior of Catholics in the American electorate. A complex array of variables including religious commitment, generational differences, social status, and policy attitudes account for limited change in partisan alignment among American Catholics. The analyses expose the long-term, durable nature of partisan attachment, as older generation Catholics who register as actively committed to their religion also remain committed Democrats. Therefore, older Catholics have not been part of the broader ideological realignment which has taken place among other religious adherents, namely evangelical and …

Do You Have A Friend?: The Impact Of Personal Knowledge Of Someone With Aids On Attitudes Towards Aids, Leith Leonce Lombas Jan 2004

Do You Have A Friend?: The Impact Of Personal Knowledge Of Someone With Aids On Attitudes Towards Aids, Leith Leonce Lombas

Electronic Theses and Dissertations

The study of attitudes towards those with AIDS is relatively recent. Most studies have examined attitudes concerning health and medical concerns. Little research has focused on attitudes toward social and behavior concerns. The few that have focused on such attitudes have employed relatively small samples collected primarily out of convenience. The studies that have used national samples have primarily addressed public policy issues. Using national data from the 1988 General Social Survey, this paper examines the effects of personal knowledge about the AIDS virus and other attitudinal variables on four dimensions of social and behavioral concern for those with AIDS …

Social Underdevelopment In Sub-Saharan Africa, Michelle L. Wingo Jan 2004

Social Underdevelopment In Sub-Saharan Africa, Michelle L. Wingo

Electronic Theses and Dissertations

For the past thirty years Africa has produced a more noticeably inferior reserve of human capital than other developing regions. This is puzzling because at the inception of independence, the future of Africa looked promising. However, during the 1970s both the political and economic situation in Africa began to deteriorate, and since 1980, the aggregate per capita GDP in sub-Saharan Africa has declined at almost one percent per fiscal year. Thirty-two countries are poorer now than they were twenty years ago, and sub-Saharan Africa is now the lowest-income region in the world despite the fact that during the last two …

The Effects Of Psuedo-Altruistic Behavior On The Likelihood Of Reciprocity And Perceptions Of The Source, Reagan Rule

Electronic Theses and Dissertations

The current study examines the roles of expectancy disconfirmation and pseudo-altruistic behaviors as communication strategies to increase receiver compliance, and their effects on perceptions of the source, including credibility and likeability ratings. While adding to the previous research, this investigation examines the effects on compliance when pseudo-altruistic practices are employed in a sales situation. Additionally, subjects’ compliance responses in the treatment groups are analyzed for relationships between compliance and several possible mediators, including participant’s evaluations of the source, and feelings of obligation and guilt. A focus group was held to discuss the face validity of the scenarios. Additionally, a pilot …

Determinants Of Financial Condition: A Study Of U.S. Cities, Lynda Dennis Jan 2004

Determinants Of Financial Condition: A Study Of U.S. Cities, Lynda Dennis

Electronic Theses and Dissertations

How well a local government is able to provide for the needs and preferences of its citizens generally depends on the financial resources available; and, how such resources are allocated, distributed, and managed. Demographics, size of local government, supply and age of infrastructure, financial position of the government, and the local economy represent a few of the factors affecting what public goods and services citizens prefer. Internal systems of accounting and control affect the allocation, distribution, and management of financial resources. As such, these internal systems significantly affect the provision of public goods and services. The research outlined in this …
