An Examination Of Potential Moderators In The Relations Between Mothers' And Fathers' Parenting Practices And Children's Behavior, Michelle Rae Gryczkowski

Dissertations

Research suggests that ineffective parenting practices play a central role in the development of children’s antisocial behavior. However, there is a lack of studies that relate parenting practices to positive child outcomes, examine the role of fathers’ parenting in the socialization of children, and test for potential moderators. Thus, the current study aimed to address these limitations by examining the relations between mothers’ and fathers’ parenting practices and child externalizing and prosocial behavior, and to determine whether the child’s sex, age, or ethnicity moderate these relations. Participants included 131 couples with a child aged 6 to 17. Data were collected …

The Use Of A Timeout Intervention With And Without Escape Extinction For Treatment Of Escape-Maintained Noncompliance In A Classroom Setting, Joshua Loren Needelman

Dissertations

The present study investigated the effectiveness of two time-out (TO) procedures in reducing escape-maintained noncompliance of four children in a classroom setting. Participants were screened to assess that compliance with teacher-presented instructions was low and noncompliance was escape-maintained. Teachers were then trained to use two TO procedures, one without escape extinction (EE) and one with escape extinction following TO release. Two nonconcurrent multiple baseline across participants designs with a crossover element were used to compare levels of compliance across baseline, TO, and TO-EE phases. Increases in compliance were seen from baseline to the first intervention phase, and these increases were …

The Relation Between Anger Rumination, Provocation, And Aggressive Behavior, Joshua Stephen Bullock

Dissertations

Maladaptive, excessive anger rumination, conceptualized as self-focused attention towards thoughts and feelings associated with the emotion of anger, has been linked to actual aggressive behaviors. In general, the emotional experience of anger in response to provocation is a well-known antecedent of aggression. Anger rumination may be associated with increased risk for aggressive behavior by maintaining and lengthening the experience of anger. It is therefore reasonable to posit that individuals high in anger rumination may be more inclined to expend greater effort to aggress in response to provocation compared to low ruminators. That is, high ruminators when angered may be more …

The research findings supported the work of Tomlinson, McTighe, Webb, Wiggins, Vygotsky, and Gardner. Their literature served as a foundation in the identification of the variables …

The Effects Of Early Intervention On The Cognitive And Social Development Of Kindergarteners, Jennifer Foster Pope

Dissertations

Research has, for years, linked early intervention with student achievement. Students coming from an appropriate developmental preschool program are at an advantage and are readily able to face the rigor of elementary school (Campbell & Ramey, 1994). This study investigated whether there were statistically significant relationships among preschool attendance, gender, free/reduced status, and ethnicity and the cognitive development of kindergarten students as measured by AIMSweb Progress Monitoring and Response to Intervention System. This study also investigated the relationship between social skills competence and the cognitive development of kindergarten students as measured by the School-age Social and Emotional Adaptive Skills Inventory. …

An Examination Of The Adjustment Of First Generation African American Male College Students, Adina Narcisse Green

Dissertations

Little is known about the college adjustment of first generation African American male students. The purpose of this study was to examine the college adjustment of this subgroup of students and create a profile of African American male college students as it relates to adjustment. In addition, research has found that students who do not integrate well into the college environment, both academically and socially, have a higher chance of incompletion. With African American males exhibiting the lowest retention and graduation rates among their gender and racial counterparts, investigating their levels of adjustment might aid in explaining their high rates …

Results indicated a statistically significant relationship between mathematical teaching self-efficacy (efficacy) and mastery approaches to instruction, as well as …

Minority Group Threat And Racial Profiling: An Analysis Of Pretextual Traffic Stops And Outcomes In Missouri Municipalities, Pernell Witherspoon

Dissertations

Racial profiling remains a controversial societal issue due in part to difficulties in determining its prevalence. Some analysts have proposed that criminological theories should be used to explain racial profiling. Using the minority group threat hypothesis, this dissertation analyzes the effects of Black population increases on race-based pretextual stops in 113 Missouri municipalities with sizable Black populations. The research also analyzes the effects of the growth and size of the Black population on traffic stop outcomes, including searches, contraband found, arrests, and citations. Other variables that might explain pretextual stops and traffic stop outcomes, including violent crime rates and socioeconomic …

The Effectiveness Of Articulation And Transfer Agreements Between Missouri Community Colleges And Universities In Promoting The Successful Completion Of A Four-Year Degree, Katherine Sue Perkins

Dissertations

American community colleges have become important in the pursuit of a four-year degree. The state of Missouri established an Associates of Arts degree and the 42-hour general education block option to assist students with transfer and degree completion in the shortest time possible. If articulation agreements in Missouri are promoting ease of movement through higher education systems as desired, the total number of terms and hours accumulated to the completion of a four-year degree should not vary among transfer students and native university students. Using Tinto’s Student Integration Model as a theoretical framework, this study compares the number of semesters …

The Molecular Transport And Intercalation Of Guest Molecules Into Hydrogen–Bonded Metal-Organic Frameworks (Hmofs), Greg Anthony Hogan

Dissertations

The process of molecular transport and intercalation has been widely studied for many years, resulting in the discovery of molecular frameworks that are capable of hosting guest molecules or ions. Layered and porous metal-organic frameworks (MOFs) have been found to have applications in the field of catalysis, storage, separations, and ion-exchange. While MOFs are perhaps stronger materials, HMOFs have the advantage of being easily modifiable and more flexible. Because HMOFs have not been extensively studied for their ability to host molecules, and because their ability to withstand guest loss and guest exchange is essentially unknown, here we report the synthesis …

Since No Child Left Behind and the need for school districts to meet the goals of Adequate Yearly Progress, it is no longer enough to limit summer learning loss. Now school leaders find it necessary to use the summer months to increase student achievement and prepare students for rigorous learning in the coming school year. This collaborative, quantitative study is an examination of one district’s attempt to improve summer programming in order to meet the need for increased student achievement. …

A Similarity Matrix For Irish Traditional Dance Music, Padraic Lavin

Dissertations

It is estimated that there are between seven and ten thousand Irish traditional dance tunes in existence. As Irish musicians travelled the world they carried their repertoire in their memories and rarely recorded these pieces in writing. When the music was passed down from generation to generation by ear the names of these pieces of music and the melodies themselves were forgotten or changed over time. This has led to problems for musicians and archivists when identifying the names of traditional Irish tunes.

Almost all of this music is now available in ABC notation from online collections. An ABC file …

The Effect Of Enrollment In Middle School Challenge Courses On Advanced Placement Exams In Social Studies And Science, Katherine Glaude-Bolte

Some middle schools offer Challenge, or honors, courses for students who have demonstrated high ability. High schools often offer Advanced Placement (AP) courses, which are taught at the college level. This study examined the correlation between enrollment in middle school Challenge courses and subsequent AP exam category scores in social studies and science in a suburban school district. The independent variables were the number of years of enrollment in middle school social studies or …

Activation Of The Innate Immune Response By The Alzheimer's Amyloid Beta Protein Via Toll-Like Receptors, Udan Lourdes Maria

Dissertations

Alzheimer’s Disease (AD) is the most common form of neurodegenerative disease characterized by the generation and deposition of amyloid beta plaques and the formation of neurofibrillary tangles. A wealth of data now demonstrate that inflammation is a prominent feature in AD pathology and a potential therapeutic target for the treatment and prevention of the disease. The emergence of evidence linking amyloid beta protein (Aβ), the primary component of senile plaques, to inflammation has led to new insights into understanding AD pathology. Aβ, a protein fragment resulting from cleavage of human amyloid precursor protein (APP), primarily exists in two forms: a …

Student And Teacher Perspectives Of Technology Usage, Lori L. Elliott

Dissertations

This study examined the use of technology by eighth grade students and teachers and perceptions of students and teachers toward technology use in the classroom and home. A mixed design method was selected to collect and analyze the data. Face-to-face interviews, field notes, and national survey results were used to triangulate the data. Three themes emerged from the study in response to the research questions: communication is the focus of technology use, students consider themselves more knowledgeable about technology than teachers, and technology use in the classroom is primarily a visual tool, rather than an interactive resource. Implications for educators …

To obtain a deeper understanding of the longitudinal effects of different contingency factors on knowledge outcomes and performance of workgroups, this dissertation was guided by the research question: Which factors, from the five categories of factors (a) characteristics of the workgroup; (b) characteristics of the tasks assigned to the workgroup; (c) the interface between the workgroup and the tasks; (d) characteristics of the knowledge required …

Development Of A Tool For Windfarm Site Analysis In Electrical Networks With High Levels Of Wind Power Generation, Edward Carroll, John Mcgrory

Dissertations

Controlling electrical networks that contain high levels of wind power will be a challenge facing many System Operators in the coming years. The intermittency and uncertainty of the power supplied by wind turbines create difficulties surrounding scheduling of plant, operating reserve and grid integration. The current process for windfarm selection is carried out by an individual stakeholder and lacks the consideration for all other stakeholders involved, which can create problems in the long term when the levels of wind power increase on the network. This paper proposes a collective approach to analysing potential windfarm sites using the key factors which …

The Role Of Puf3p And Puf4p In The Regulation Of Mrna Decay In Yeast Saccharomyces Cerevisiae, Florencia Andrea Lopez Leban

Dissertations

Proper regulation of gene expression at a cellular level is required in all organisms for their successful adaptation and survival to physiological or environmental changes. In eukaryotes, a convenient way of regulating gene expression is achieved by post-transcriptionally adjusting the decay rates of different mRNAs. The Puf family of proteins in yeast belong to a widespread group of eukaryotic RNA-binding proteins that regulate the lifespans of target mRNAs by sequence specifically binding to 3' untranslated regions (UTRs) and modulating their decay rates. For example, the yeast Puf3 protein binds the COX17 3' UTR, stimulating its deadenylation and subsequent decay. However, …

Mothers Who Use Illicit Drugs:An Exploration Of Professional Workers’ Perceptions Towards Mothers Who Use Illicit Drugs, Julieann Lane

Dissertations

Although much has been written in recent times about women’s drug use, there has been a scarcity of research into motherhood and drug use in Ireland as it remains both a complex and sensitive issue. Since the 1980’s Ireland has seen a dramatic and unprecedented increase in the availability of illicit drugs. This increased availability reflects rising consumption of illicit drugs amongst women. The aim of this study was to explore the perceptions that a sample of professional workers hold of mothers who use illicit drugs in Ireland. The study reviews the literature applicable to the area of drug use …

Early School Leaving : An Exploration Of The Factors Contributing To School Non-Completion, Jennifer Mcgarr

Dissertations

This study is of an explorative nature, investigating early school leaving in Ireland today. Despite a range of interventions to address school non-completion, approximately 14% of students (as of 2007) continue to leave school without completing their education every year (Byrne & Smyth, 2010). A disproportionate amount of these young people come from disadvantaged backgrounds (Barnardos, 2006). Education is a powerful predicator of life chances and opportunities. Those who leave school with little or no formal education have less opportunities in later life, are more likely to be unemployed, have lower levels of general health and are at a greater …

“It’S Like Throwing A Pebble Into Water And There Is A Ripple Effect Throughout The Entire Pond” The Effect Of Drug Use On The Family System, Aoife Stack

Dissertations

Alcohol and drug problems affect not only those using these substances but also family members of the individual substance user. There has been a historic neglect within the addiction sphere of both research and practice pertaining to the effect of drug use on the family. Each family member is uniquely affected with negative outcomes ranging from economic hardship to violence being perpetrated against them (Csiernik, 2002). Thus, treating only the individual with the substance problem is limiting and serves an overly narrow orientation for the enhancement of both family and community health. This study addressed an important gap in literature …

Opting In And Staying In: Older Teenagers’ Decisions On Becoming And Remaining Involved In Youth Services In Dublin City., Kerri Martin

Dissertations

It is widely recognised in Ireland and internationally that the engagement of young people in the youth work process brings with it a range of positive benefits and outcomes, both for the young people involved and society in general. However, it has also been found that young people aged 15-19 participate less in youth services and therefore do not gain the associated benefits. This dissertation explores the perspectives of young people aged 15-19 who are engaged in youth services in Dublin City, in relation to their decisions to become and remain involved in youth services. The aim of this research …

Causes Of Nonattendance And Its Effect On Student Achievement At The High School Level, Kelly D. Bracht

Dissertations

Many high schools in America have issues with student nonattendance. The researcher designed this mixed methods study to determine the affect of nonattendance on student achievement and to ascertain whether home-related factors or school-related factors were more significant causes of nonattendance. Both the high school in this study and other similar schools may use the results to develop effective nonattendance intervention programs. The researcher used cluster sampling to determine the sample population. She then collected attendance data (the number of absences each student had during one semester) and achievement data (each student’s Grade Point Average during that same semester) about …

Lost Relationships : An Exploratory Study Of The Factors Associated With Non-Resident Parents Losing Contact With Their Children Following Separation/Divorce, James (Sé) Fulham

Dissertations

Irish society, through its laws, institutions and civic organizations, promotes the primacy of the family, as the environment for the development of the loving, secure, supported child. Ireland, in keeping with most western societies, has witnessed a steady increase in family breakup since the 1960s. The impact of parental separation and family breakup on the child has been found, generally, to be very negative, with the exception of children in highly conflictual parental homes. Little attention has been paid to date, to the factors leading to loss of contact and to the views and experiences of absent parents, those who …
