Burnout And Job Dissatisfaction Among Practicing Illinois School Psychologists: A 1994 To 2004 Comparison, Nikolaus J. Hoffman Jan 2005

Burnout And Job Dissatisfaction Among Practicing Illinois School Psychologists: A 1994 To 2004 Comparison, Nikolaus J. Hoffman

Masters Theses

The purpose of this study was to identify the primary variables associated with burnout among practicing Illinois school psychologists. More specifically, the purpose was to determine if the same variables that correlated highly with Illinois school psychologists burnout levels in a 1994 study by Niebrugge have held constant over the last decade. Survey materials used in the 1994 study, including the Maslach Burnout Inventory, a School Psychologists Stress Inventory, and a specially designed job satisfaction questionnaire were completed by a random sample of members of the Illinois School Psychologists Association (N = 52). As in the 1994 study, results suggested …

Illinois Standards Achievement Test (Isat) Reading Test Performance And Oral Reading Rate Of 3rd And 5th Grade Illinois Students, Angela R. Herrera Jan 2005

Illinois Standards Achievement Test (Isat) Reading Test Performance And Oral Reading Rate Of 3rd And 5th Grade Illinois Students, Angela R. Herrera

Masters Theses

The relationship between Illinois Standard Achievement Test reading scores for 3rd and 5th graders and their oral reading fluency rates was examined. Four hundred fifty nine students in those grades were given reading probes to determine their reading rate. Reading rate was defined as words read aloud per minute correctly on reading probes composed of text from the students' basal readers as measured by the classroom teacher. The Illinois Standard Achievement Test (ISAT) reading test results were obtained in the spring of each year in a group format. The results indicated a modest correlation between the two sets of data. …

Effects Of Interspersing On Peer Tutoring Of Sight Words, Jennifer Schultz

Masters Theses

This study investigated the effects of short-term peer tutoring, with interspersal or without interspersal, on sight word acquisition. Four first grade students and two second grade students participated in the study. Student dyads (i.e., 1 tutor and 1 tutee) were either in the without interspersal condition or in the interspersal condition. Using an AB single case design, student performance was measured and graphed in two ways, cumulative learning and student learning rate. Contrary to expectations, results indicated the overall cumulative learning measurement for students in the without interspersal condition acquired the greater number of words learned, required less instructional time, …

An Investigation Of The Influence Of Hope On The Relationship Between Racial Discrimination And Depressive Symptoms Among African American College Students, Jennifer L. Vanderzee '05 Jan 2005

An Investigation Of The Influence Of Hope On The Relationship Between Racial Discrimination And Depressive Symptoms Among African American College Students, Jennifer L. Vanderzee '05

Honors Projects

The relationship between perceived racial discrimination, hope, and depressive symptoms among African American college students was investigated. The first supported hypotheses were that racial discrimination, hope, and hope's two components, agency and pathways, would each significantly affect depressive symptoms. Hope and pathways, but not agency, were each found to moderate the relationship between racial discrimination and depressive symptoms and the moderation models were found to explain as much or more variance the models examining direct effects. Also, the interaction of pathways and racial discrimination explained more variance than any of the other models. These results suggest that hope and pathways …

A Context-Dependent Model Of Proximity In Physically Situated Environments, John D. Kelleher, Geert-Jan M. Kruijff Jan 2005

A Context-Dependent Model Of Proximity In Physically Situated Environments, John D. Kelleher, Geert-Jan M. Kruijff

Conference papers

The paper presents a computational model for a context-dependent analysis of a physical environment in terms of spatial proximity. The model provides a basis for grounding linguistic analyses of spatial expressions in visual perception. The model uses potential fields to model spatial proximity. It has been implemented, and when combined with a handcrafted grammar, is used to enable a conversational robot to carry out a situated dialogue with a human. The key concept in our approach is defining the region that is proximal to a landmark based on the spatial configuration of other objects in the scene. The model extends …

The Efficacy Of Noncontingent Escape For Decreasing Disruptive Behavior During Dental Treatment, Patrick Michael O'Callaghan Jan 2005

The Efficacy Of Noncontingent Escape For Decreasing Disruptive Behavior During Dental Treatment, Patrick Michael O'Callaghan

LSU Doctoral Dissertations

Researchers have developed and demonstrated the effectiveness of a number of interventions to manage disruptive behavior in the dental setting. However, these treatments vary in terms of their effectiveness, invasiveness, effort to implement, and acceptability to families. This study evaluated the effects of noncontingent escape for reducing disruptive behavior in a pediatric dental setting. Within a multiple baseline design across subjects, five children were provided response-independent breaks via an automated cuing device. Results demonstrated reductions in escape-related behaviors (e.g., crying, body movements) for all children. Additionally, the intervention was implemented with high integrity and was favorably rated by the dental …

The Effects Of Discrimination Training On Choice-Making Accuracy During Symbolic Perference Assessment Formats, Christina Marie Vorndran Jan 2005

The Effects Of Discrimination Training On Choice-Making Accuracy During Symbolic Perference Assessment Formats, Christina Marie Vorndran

LSU Doctoral Dissertations

The right of individuals with developmental disabilities to live fulfilling and normalized lives has been a focus of federal legislation and applied research over the past 30 years. Research has primarily focused on the identification and incorporation of preferred items and activities into the home and community environments of these individuals. Because of cognitive and communication limitations, some individuals with developmental disabilities require training to make choices that accurately reflect their preferences. Verbal choice methods are commonly used in everyday clinical practice; however, the accuracy of these methods for identifying actual preferences depends on the individual’s ability to make auditory …

Literature Review: Diagnostic Utility Of The Million Clinical Multiaxial Inventories In Various Settings : The Detection And Effect Of Faking Good ; Research Project : The Impact Of Faking-Good On The Mcmi-Iii : Implications For Child Custody Evaluations, Paul Lenny

Theses : Honours

Research surrounding the ability of the Millon Clinical Multiaxial Inventory (MCMI; Millon, 1977, 198 7, 1994) to detect faking good was reviewed; along with the effect faking has on diagnostic accuracy. Limited research indicates moderate success of the MCMI validity indices (VI) at detecting faking good. Suggested improvements include developing a fake-good profile combining the personality scales and VI and developing new base rate adjustments with populations likely to fake good. Faking good reduces the overall diagnostic accuracy of the test but determining local base rates of faking to produce optimal cut-offs for the VI would improve diagnostic utility. Future …

The Relationship Between Self-Esteem, Self-Efficacy And Sense Of Belonging In Young Adolescents At School, Elisabeth Freeman Jan 2005

The Relationship Between Self-Esteem, Self-Efficacy And Sense Of Belonging In Young Adolescents At School, Elisabeth Freeman

Theses : Honours

Research emphasises the importance of adolescents' psychological sense of belonging in relation to academic, motivational, psychosocial, developmental, and behavioural outcomes, particularly during transition to high school. However, adolescents' adjustment during transition period does not occur in isolation, it occurs in conjunction with normative biopsychosocial change-related effects. As most of adolescents biopsychosocial needs are negotiated in high school, the school's social context assumes a fundamental role in facilitating successful adolescent adjustment, and school belonging. Features of the high school context such as perceived peer, parent, and teacher support have an influence on adolescents' perceived belonging. Similarly, the educational values, in terms …

An Exploration Of Non-Residential Fathers' Relationship With Their Children: Working Towards A Positive Psychology Approach, Suzanne Ray Jan 2005

An Exploration Of Non-Residential Fathers' Relationship With Their Children: Working Towards A Positive Psychology Approach, Suzanne Ray

Theses : Honours

In western culture, the majority of fathers become the non-residential parent after separation and it is reported many disengage from their children as time goes on. This review will elucidate the effects of separation on the father role. Within this body of literature there are two dominant ideologies pertaining to fathers – father absence and father importance. The findings from research support that the quality of contact rather than quantity of contact is important for close bonds between non-residential fathers and their children. There are a number of factors that can help or hinder this relationship which are intrinsically linked …

Home To Jesus (Chapter 9 On Finding Our Way Home), Mark R. Mcminn Jan 2005

Home To Jesus (Chapter 9 On Finding Our Way Home), Mark R. Mcminn

Faculty Publications - Doctor of Psychology (PsyD) Program

Excerpt: "Like so many, I was raised in a religious home- praying before meals, attending Sunday services, seeking to follow God's will for my life. I remember getting two Christmas presents in ninth grade-a new pair of skis and a new Bible. Honestly, I was more thrilled with the Bible than with the skis (though both gifts made me ecstatic about my generous parents for a few days). I remember wondering in those youthful years why anyone would choose a life apart from Jesus. As I grew toward adulthood I began to understand their reasons. The faith I had loved …

Effects Of A School-Based Social-Emotional Competence Program: Linking Children's Goals, Attributions, And Behaviors, Karin S. Frey, Susan Bobbitt Nolen, Leihua Van Schoiack Edstrom, Miriam K. Hirschstein

Faculty Publications - Doctor of Psychology (PsyD) Program

This study examined the effects of the Second Step social–emotional learning program and addressed the relations between social cognitions and prosocial and antisocial behavior. Children (N = 1,253) in intervention and control groups were assessed by teacher ratings, self report, and observation in two conflict situations. Intervention children were more likely to prefer prosocial goals and give egalitarian reasons for satisfaction than control children. Intervention children also required less adult intervention, and behaved less aggressively and (among girls) more cooperatively. Teacher ratings of social behavior showed improvement over time. Individual and dyadic behavior varied as a function of goals, hostile …

'The Steps To Respect' Program Uses A Multilevel Approach To Reduce Playground Bullying And Destructive Bystander Behaviors, Karin Frey, Leihua Van Schoiack Edstrom, Miriam Hirschstein Jan 2005

'The Steps To Respect' Program Uses A Multilevel Approach To Reduce Playground Bullying And Destructive Bystander Behaviors, Karin Frey, Leihua Van Schoiack Edstrom, Miriam Hirschstein

Faculty Publications - Doctor of Psychology (PsyD) Program

Bullying reduction efforts benefit from combining universal and selected interventions. All children are involved occasionally as aggressor, victim or encouraging bystander, and some children are frequently involved. Bullying behavior is amply rewarded in the school environment. The Steps to Respect program aims to reduce rewards by increasing adult intervention and support for socially responsible student behavior. Cognitive-behavioral classroom curricula address peer norms, assertiveness, and general social-emotional skills. A random control trial showed decreases in playground bullying and negative bystander behavior after one year. Longitudinal analyses showed declines in all five problem behaviors after two years. Results were strongest when teachers …

Keeping Friendships Alive: Self-Monitoring And Maintenance Strategies, Nadia Nicol Flanigan Jan 2005

Keeping Friendships Alive: Self-Monitoring And Maintenance Strategies, Nadia Nicol Flanigan

UNF Graduate Theses and Dissertations

The relationship between self-monitoring and use of maintenance strategies in friendships was examined. It was hypothesized that low self-monitors would engage in more idealization, report higher degrees of closeness, and report higher degrees of platonic love in their relationships with their best friends than would high self-monitors. Participants (81 females, 61 males) completed Snyder and Gangestad's (1986) revised Self- Monitoring Scale; Edmond's (1967) Marital Conventionalization Scale; Hendrick's (1988) Relationship Assessment Scale; the Diversity and Strength scales of Berscheid, Snyder, & Omoto's (1989) Relationship Closeness Inventory; Aron, Aron, and Allen's (1998) Desirability, Probability, Desirability of the State, and Intensity Scales; and …

Some Effects Of Self-Monitoring, Perceived Norms, And Sex-Role Stereotypes On Romantic Betrayals, Alissa Anne Garth Jan 2005

Some Effects Of Self-Monitoring, Perceived Norms, And Sex-Role Stereotypes On Romantic Betrayals, Alissa Anne Garth

UNF Graduate Theses and Dissertations

It was hypothesized that high self-monitors (compared to low self-monitors) would report more betrayals of their romantic partners. Perceptions of others' betrayals should follow sex-role stereotypes (i.e., males are more likely to betray than females). Sex-role stereotyping might be attenuated when counter-stereotypical norms are made salient. One-hundred seventy five undergraduates completed the Interpersonal Behavior Survey (Roscoe et aI., 1988) and the Self-Monitoring Scale (Snyder & Gangestad, 1986). Before doing so, participants read one of two instructional sets: females are more likely than males to betray their romantic partners; people in general are likely to betray their romantic partners. Participants responded …

Co-Parenting In Intact And Divorced Families: Its Impact On Young Adult Adjustment, Jill A. Ferrante Jan 2005

Co-Parenting In Intact And Divorced Families: Its Impact On Young Adult Adjustment, Jill A. Ferrante

Theses and Dissertations

Co-parenting is the ideal parenting relationship after divorce, characterized by involvement of both parents in all decisions regarding their children. Children who report that their parents demonstrate healthy co-parenting are generally better adjusted than their peers who experience unhealthy co-parenting. The present study examined the potential mediating roles of co-parenting and parenting practices upon the relationship between marital status and young adult adjustment. Data were analyzed via structural equation modeling. Participants were 340 undergraduate students from intact and divorced/separated families. Data were obtained via questionnaires that tapped a range of adjustment factors (i.e., mental health, fear of intimacy, work ethic, …

Does Transdermal Nicotine-Induced Withdrawal Suppression Depend On Smokers' Gender?, Sarah Ellen Evans Jan 2005

Does Transdermal Nicotine-Induced Withdrawal Suppression Depend On Smokers' Gender?, Sarah Ellen Evans

Theses and Dissertations

Nicotine replacement therapy (NRT) is a pharmacotherapy used commonly to help tobacco smokers quit smoking. All forms of NRT are demonstrably efficacious for this indication, and several forms, including transdermal nicotine (TN) are available over-the-counter in the United States. NRT is less efficacious in women than in men, although the specific reasons for this gender difference are unknown. NRT generally, and TN specifically, is thought to work, at least in part, by suppressing withdrawal symptoms in abstinent smokers. While TN-induced withdrawal suppression has been demonstrated, the degree to which this withdrawal suppression is influenced by smokers' gender is uncertain. The …

Intracellular Ph, The Proximate Signal For Cell Volume Changes That Are Mediated By The Actin Cytoskeleton, William Pasley Jan 2005

Intracellular Ph, The Proximate Signal For Cell Volume Changes That Are Mediated By The Actin Cytoskeleton, William Pasley

Theses and Dissertations

The relationship between initial intracellular pH (pHi) and associated cell volume change was investigated by simultaneous measurement of pHi and cell volume with fluorescence imaging in polarized fungiform taste receptor cells (TRCs) loaded with BCECF in vitro. Ammonium pulses caused a brief, reversible alkalinization in pHi and induced cell swelling. Sodium-acetate pulses reversible decreased TRC pHi and induced cell shrinkage. Removal weak acids and return to Control Ringer's solution (CR) causedTRC pHi and volume to overshoot baseline levels before fully recovering. Replacing CR with zero-sodium solution resulted in irreversible acidification of TRC pHi and induced cell swelling. Addition of sodium …
