Middle School Teachers' Perceptions Of Barriers Of Managing Student Behavior, Winifred Nicole Whitlock Jan 2011

Middle School Teachers' Perceptions Of Barriers Of Managing Student Behavior, Winifred Nicole Whitlock

Walden Dissertations and Doctoral Studies

Despite training and support, many middle school teachers struggle to create, implement, and enforce research-based strategies to manage students' behaviors. The purpose of this case study was to examine teachers' perceptions about the barriers of managing student behavior. The research questions investigated 9 teachers' perceived barriers of managing student behavior at one middle school and the observed actions of these teachers' reactions to student behavior. Each participant was asked to participate in a 45-minute semistructured interview to examine their perceived barriers of managing student behavior and the strategies they use to manage student behavior relative to McGregor's theories X and …


Roles Of Internal Locus Of Control And Self-Efficacy On Managing Job Stressors And Ryff's Six Scales Of Psychological Well-Being, William A. Howatt Jan 2011

Roles Of Internal Locus Of Control And Self-Efficacy On Managing Job Stressors And Ryff's Six Scales Of Psychological Well-Being, William A. Howatt

Walden Dissertations and Doctoral Studies

The purpose of this study was to investigate the roles internal locus of control and self-efficacy play in moderating how employees manage their perceived work stress and positively engage in the behaviors that facilitate autonomy, environmental mastery, personal growth, self-acceptance, positive relations with others, and purpose in life. Investigators have documented the relationship between perceived workplace stress and strain and showed that how employees cope with perceived stress influences their psychological and physical health. However, there is less information available about the relationship between how employees cope with perceived workplace stress and engage in behaviors that facilitate their psychological well-being. …


The Differential Effects Of Genetic And Dietary Alterations In Folate Status On Prefrontal Cortical Functions, Jessica Amanda Ash Jan 2011

The Differential Effects Of Genetic And Dietary Alterations In Folate Status On Prefrontal Cortical Functions, Jessica Amanda Ash

Legacy Theses & Dissertations (2009 - 2024)

Folate status plays an essential role in embryogenesis and brain development; however, its importance in supporting cognitive functioning throughout adulthood is less clear. The present study was interested in examining the effects of genetic and dietary alterations in folate status on prefrontal cortical functions in mice, modeling a common polymorphism in the MTHFD1 gene in folate metabolism. A factorial design was used crossing two genotypes (mice with a gene trap insertion in the Mthfd1 gene exhibiting 50% decreased Mthfd1 expression: Mthfd1gt/+ mice or wildtype mice) with two levels of dietary folate (folate sufficient or folate deficient). The mice were tested …


Features Of The Human Body And Voice : The Biological Impact On Perception And Attraction Through Multiple Sensory Domains, Roy Nathan Pipitone Jan 2011

Features Of The Human Body And Voice : The Biological Impact On Perception And Attraction Through Multiple Sensory Domains, Roy Nathan Pipitone

Legacy Theses & Dissertations (2009 - 2024)

A growing body of literature has shown that variation in the sound of a person's voice conveys important information about our underlying biology. The present studies further investigate how the human voice can be used as a medium that disseminates characteristics related to mate quality and attraction. The human voice has been shown to be affected by cyclic hormonal fluctuations across the menstrual cycle, and raters show preferences for voice recordings at heightened fertility times compared to other times during the menstrual cycle. In the current studies, this finding was replicated multiple times and less masculine males were found to …


Short-Term Nicotine Abstinence And Decision Making, Gabriel D. Searcy Jan 2011

Short-Term Nicotine Abstinence And Decision Making, Gabriel D. Searcy

Dissertations

Research has shown that acute drug administration may affect impulsivity (i.e., choice for small, immediate rewards over large, delayed rewards) on laboratory delay-discounting tasks. Few studies have investigated how drug abstinence affects impulsivity. Investigating how drug abstinence affects impulsivity may be relevant to preventing relapse. Two previous studies have investigated the effects of short-term nicotine abstinence on impulsivity using delay-discounting tasks. The results were mixed, one study suggested that choices became more impulsive (i.e., delayed money was devalued) under nicotine deprivation. One goal of the present research was to further investigate how nicotine deprivation affects delay-discounting for money rewards. In …


Inherited Obsession: The Role Of Genetics And Serotonin In The Etiology Of Obsessive-Compulsive Disorder, James E. Sottile Jan 2011

Inherited Obsession: The Role Of Genetics And Serotonin In The Etiology Of Obsessive-Compulsive Disorder, James E. Sottile

Senior Projects Spring 2011

We still do not understand why some individuals are more likely to develop OCD than others. Research has implicated the serotonin system specifically the serotonin transporter and the 5-HT2A receptor as potential neurochemical underpinnings of OCD. Innovations in genetics have allowed research to hone in on the specific genes which code for the neurochemical dysfunction implicated in OCD. In this literature review, I gathered data in the form of research which addresses the neurochemical and genetic underpinnings of OCD in order to gain a better understanding of the etiology of the disorder. The findings presented represent my analysis of …


Neuropsychological Instruction: A Process Related Approach In Early Reading Skill Development, Karen Boyle Donahue Jan 2011

Neuropsychological Instruction: A Process Related Approach In Early Reading Skill Development, Karen Boyle Donahue

PCOM Psychology Dissertations

Proficient and fluent reading ability for all Americans continues to be a highly prioritized, yet under achieved aspiration in current educational institutions. The acquisition of proficient reading fluency and comprehension are, undoubtedly, the most essential priorities in the academic development of school aged children, yet a discouraging number of students continue to struggle with the reading process throughout school aged years. Research has targeted key instructional areas that must be implemented in successful reading curriculum in the early childhood years. Namely, phonological awareness, phonics instruction, reading fluency, vocabulary development, and reading comprehension are core components that must be incorporated into …


Repeated Binge Pattern Ethanol Administration During Adolescence Or Adulthood: Long-Term Changes In Voluntary Ethanol Intake And Mesolimbic Dopamine Functionality In Male Rats, Antoniette Michelle Maldonado-Devincci Jan 2011

Repeated Binge Pattern Ethanol Administration During Adolescence Or Adulthood: Long-Term Changes In Voluntary Ethanol Intake And Mesolimbic Dopamine Functionality In Male Rats, Antoniette Michelle Maldonado-Devincci

USF Tampa Graduate Theses and Dissertations

Binge alcohol consumption is a rising concern in the United States, especially among adolescents as during this developmental period alcohol use is usually initiated and has been shown to cause detrimental effects on brain structure and function. These findings have been established through the use of binge models in animals, where animals are repeatedly administered high doses of ethanol typically over a period of three or four days. While such work has examined the effects of a four-day and repeated three-day binge, there has been almost no work conducted aimed at investigating the long-term behavioral and neurochemical and/or functional consequences …


Sex-Typical Body Shape, Quality Indicators And Behaviors, Kyungok Sim Jan 2011

Sex-Typical Body Shape, Quality Indicators And Behaviors, Kyungok Sim

Legacy Theses & Dissertations (2009 - 2024)

According to evolutionary theory, sex-typical body shapes (a man's muscular physique and a woman's hourglass figure) are an outcome of evolutionary adaptation in reproductive fitness because they convey information about gene quality, health and fertility, which are important elements for mate selection. The purpose of this study was to investigate whether sex-typical body shape predicts individual variation in morphological traits that signal quality [fluctuating asymmetry (FA), hand grip strength (HGS), digit ratios (2D:4D) and leg-to-torso ratio (LTR)] and in psychological masculinity/femininity and the role of these in reproductive fitness. The results revealed that a man's masculine body shape predicted low …
