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
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. …

Self-Hypnosis And Volitional Control Of Finger Temperature Among Adults, Joseph Swope
Walden Dissertations and Doctoral Studies
Raynaud's disease is a condition in which circulation to the hands becomes restricted, causing an uncomfortable sense of cold and occasionally injury. The cause of Raynaud's disease is unknown. Earlier studies have shown that hetero-hypnosis is effective in the treatment of Raynaud's disease. Cost and access to providers limit such a treatment's availability. Theories of hypnosis suggest that self-hypnosis underlies all hypnotic processes. This study examined the utility of self-hypnosis and focused attention on the volitional control of hand temperature. Forty-three adult participants ranging in age from 19 to 77 years with no hypnosis experience were randomly divided into 2 …

The Relationship Between Depression And Cognitive Deterioration In Older Adults, Rakesh Chand
Walden Dissertations and Doctoral Studies
The population structure of the United States is changing; the older age group is increasing in size relative to the younger generation. The trend is expected to continue, especially starting in 2020, when the baby boomer population---estimated at 80 million---will be reaching their 65 th birthday, a time associated with increasing health complications, including depression and dementia. The study employed a holistic paradigm as the conceptual framework to examine the association between depression and dementia in older adults, and generated a grounded theory to illuminate the relationship between depression and dementia. This theory was then used to assess the efficacy …

Attachment, Parentally Bereaved Adolescents, And High School Outcomes In A Large Inner-City High School, Silvana Amar
Walden Dissertations and Doctoral Studies
U.S. and world communities face the challenges of understanding how children grieve and of giving them sufficient social and educational support. Inner-city minority adolescents have not been represented well in the bereavement and attachment literature. The purpose of the quantitative study was to use the attachment theory to understand the impact of parental bereavement on these adolescents. Data were collected using the Adult Attachment Interview (AAI), the Piers-Harris Children's Self- Concept Scale (2nd ed.), and school records. MANOVAs were used to analyze the influence of attachment organization, bereavement status, and gender on self-concept and academic and behavioral functioning in school. …

Implementing Core Values In The High-Tech Industry, Arthur J. Smith
Walden Dissertations and Doctoral Studies
Previous research has indicated that the path-goal theory is an effective way to study leadership behavior; however, a gap exists in the literature with respect to its achievement-oriented and participative leadership dimensions in high-tech organizations. In this quantitative study, the effects of a core values intervention on the four leadership dimensions of House's path-goal theory were evaluated at a semiconductor manufacturer with a focus on the differences between supervisors and non-supervisory personnel. Data were gathered from the validated, company-developed Corporate Culture Survey that was administered pre and post intervention. Data were also gathered from a categorization task that sorted the …

Spirituality And Depression In Parents With Children In Oncology Or Hematology Treatment, Kurt D. Soell
Walden Dissertations and Doctoral Studies
The psychological burden of cancer treatment affects not only child patients but also their parents. There is extensive literature on the positive influence of spirituality on the cancer patient. But there is a gap in the literature on the potential healing influence of spirituality on the parent of the cancer or hematology patient. The purpose of this study was to examine the relationship between spirituality and parents' levels of depression and anxiety during their child's hematological or oncology treatment. Using the transtheoretical model of change, a purposive sample of 48 parents of children undergoing cancer or hematology treatment completed a …

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
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 …

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
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 …
Mechanisms For Decisions About The Future,

Mechanisms For Decisions About The Future, Jeffrey R. Stevens
Jeffrey Stevens Publications
Evolutionary and psychological perspectives on decision making remain largely separate endeavors. The bounded rationality approach integrates these two perspectives by focusing on simple, plausible mechanisms of decision making and the cognitive capacities needed to implement these mechanisms. Decisions about the future provide a class of decisions that lend themselves to a bounded rationality approach. Though many different mechanisms may exist for making decisions about the future, only a subset of these mechanisms actually require a representation of the future. The bounded rationality approach helps focus on the cognitive capacities and decision mechanisms that are necessary for a full understanding of …

The Relationship Between Emotional Intelligence And Literacy Achievement Of Secondary Students, David P. Jones
Walden Dissertations and Doctoral Studies
Proficiency in language arts and communication skills is essential to success in the global workforce. Most states assess students in language arts literacy (LAL) through standardized tests that assess a student's ability to read, interpret literature, and write expressively. Although educational reformers strive to improve the foundations that prepare students in literacy, reforms have not fully incorporated the theory of emotional intelligence (EI), which explains a student's ability to use, understand, perceive, and manage their emotions in order to think critically, make decisions, and solve problems. Although it is not known whether EI directly correlates to literacy, emotional skills are …

Evaluation Of Bureau Practice For Illegal Drugs Use Among Teens, Sharon D. Heard
Walden Dissertations and Doctoral Studies
The Bureau of Substance Abuse Treatment Recovery and Prevention, which oversees drug intervention services for Detroit residents, has found the city's illegal drug use among teens to mirror national rates. Illegal drug use is associated with addiction, major health problems, and stigma. Incorporating evidence-based screening during all teen health care visits would decrease missed opportunities to identify at-risk behaviors, the number of teens that do not receive intervention, and the stigma associated with screening. The purpose of this project was to develop evidence-based policy and practice guidelines for teen screening services for illegal drug use. The Plan-Do-Study-Act (PDSA) model was …

Reward Probability And The Variability Of Foraging Behavior In Rats, W. David Stahlman, Aaron P. Blaisdell
Psychological Science Articles
The connection between reduced reinforcement probability and increased behavioral variability hasbeen well established in recent years (Gharib, Gade, & Roberts, 2004; Stahlman, Roberts, & Blaisdell, 2010). Researchers have hypothesized that this relationship is an adaptive one - it is beneficial for animals to increase behavioral variability in response to low likelihood of success,because this increase in variability potentially allows them to discover new behavioral options that are more highly rewarded. We conducted a study to investigate the relationship between behavioral variability and reward probability in an ecologically valid experimental task. We trained rats to search for hidden food in the …

Chronic stress and other emotional factors may have relevant impacts on pregnancy outcomes because they are related to neuroendocrine changes that lead to alterations in immunomodulation during pregnancy. In this quantitative prospective cross-sectional study, the relationship of emotional lability, depression, and stress during pregnancy and the development of preterm labor, preeclampsia, placental abruption, and low birth weight for gestational age babies was examined. Additionally, social support scores were compared to levels of stress/anxiety, depression, and emotional lability in pregnant women. Two hundred and forty two pregnant women who received prenatal services at the National Institute of Perinatology in Mexico City …
