Experiences Teaching Stoichiometry To Students In Grades 10 And 11, Cynthia Denise Bridges

Walden Dissertations and Doctoral Studies

Many students have problems learning stoichiometry, a complex mathematical chemistry concept used to determine how much product will be produced or formed from a given quantity of reactants. The problem addressed in this study was teachers' lack of understanding of how to teach stoichiometry in a Midwestern urban school district. The conceptual framework of the study was based upon constructivist theory. A qualitative narrative approach was used to obtain the perceptions of 5 high school chemistry instructors related to their experiences, successful or unsuccessful, in teaching stoichiometry to students in Grades 10 and 11. Data were gathered through face-to-face interviews, …

The Association Of Lead With Cataracts And Vision-Related Problems In Perimenopausal Women, Imogene Drakes

Walden Dissertations and Doctoral Studies

Around the world, women are subject to an earlier incidence of cataracts, have a higher risk for cataracts, and also have a higher risk for other vision-related problems than men. Previous research has indicated an association between endogenous lead stored in long bones and cataracts in men over 60 years of age; however, a similar study in women did not reveal an association. This case control study was conducted to investigate whether perimenopausal mobilization of endogenous lead serves as a possible causative factor for women's generalized vision issues and cataract incidence in particular. Secondary data were gathered from 1,416 women …

Learning Disability Status And Gender As Predictors Of Self-Efficacy., Irene Ekohamen Aikhomu

Walden Dissertations and Doctoral Studies

In the school district under study, students with learning disabilities were

underperforming when compared to students without disabilities. Research has indicated that improved self-efficacy can promote improved student outcomes and that self- efficacy can be taught. Despite this known association, the school district under study has not provided students with such support. The current study addressed ways in which that gap may be attenuated. Guided by the framework of Bandura's theory of self-efficacy and social cognitive theory, the purpose of this study was to explore (a) whether students' perceptions of self-efficacy differed depending on whether or not they had diagnosed …

The Effects Of Parental Motivations On Home-Based And School-Based Parental Involvement, Steve C. Strickland

Walden Dissertations and Doctoral Studies

Students at a Title I middle school in Georgia have scored low on standardized state tests for several years. Of the many possible ways to address low test scores, the school focused on increasing parental involvement, which can have a strong positive correlation with academic success. Researchers have indicated that parental involvement programs are more successful when created based on the specific motivations of parents. Therefore, the purpose of this study was to examine the effects of parental motivation on parents' home-based and school-based involvement behaviors. The theoretical framework for this study was the work of Hoover-Dempsey and Sandler who …

Utilizing Education To Change College Students' Attitudes About Mental Illness, Claudette Thompson

Walden Dissertations and Doctoral Studies

Researchers have found that public opinion of people who are mentally ill is often negative. This study, grounded in cognitive theories, was conducted to determine if education would improve college students' attitudes toward mental illness and if there were gender differences in those attitudes, as past studies had shown. Attitudes of 184 Jamacian adult college students towards mental illness were measured before and after a didactic seminar using the Attitudes to Mental Illness Questionnaire (AMIQ), Opinion About Mental Illness Scale (OMI), and Help Seeking Attitudes Scale. A nonrandomized trial was used to generate nonequivalent comparison groups, with one group attending …

The Psychological Resilience Of Spousal Caregivers Of Multiple Sclerosis Family, Marisa Diane Diaz

Walden Dissertations and Doctoral Studies

The purpose of this quantitative study was to examine an under-researched topic: the relationship between psychological resilience and personal growth with spousal caregivers of patients diagnosed with Multiple Sclerosis (MS). Chronic illnesses contribute to potentially stressful changes (i.e., lifestyle, quality of life, financial wellbeing, and interpersonal relationships) for the caregiver. The theoretical foundation for this study was Walsh's family resilience theory, which contends that resilience is vital for coping with stressful life experiences and leading a more successful life. Three separate analyses were conducted to examine the relationship between the total scores of the RS and the PGIS, the SWLS, …

Walden Dissertations and Doctoral Studies

The purpose of this phenomenological study was to examine migrant women farmworkers' views of perinatal care management while working in the fields. Like men, women migrant farmworkers are exposed to many physical, chemical, and biological hazards that pose human health risks. However, women of childbearing age are at an increased risk of having reproductive health difficulties and adverse pregnancy outcomes, and the infant mortality rate among migrant farmworkers is estimated to be twice the national average. Perinatal care is a critical factor in reducing adverse outcomes for perinatal and newborn mortality. Face-to-face interviews were conducted with 15 migrant women farmworkers …

Prostate Cancer And Afro-Caribbean Men: Experiences, Perceptions, And Beliefs, Harold Evelyn Taitt

Walden Dissertations and Doctoral Studies

Despite the high incidence of prostate cancer (PC) amongst men of African descent, there is a paucity of qualitative data that explores how Afro-Caribbean men perceive their risk, susceptibility to, and management of this disease. This phenomenological study sought to explore and analyze beliefs about PC in a sample of Afro-Caribbean men who reside in the United States (U.S.). The research questions considered the perceptions, beliefs, and lived experiences of participants.

Mental Health Administrators' Knowledge And Perceptions Of Delivery Of Relationship-Based Services, Alan Frank Singer

Walden Dissertations and Doctoral Studies

Past research has recommended that clinical mental health (CMHC) administrators employ a relational focus to their work, but little evidence exists that such a relational focus is actually being utilized. Guided by Rogers' principles of client-centered therapy, this study examined whether CMHC administrators possessed the knowledge and attitudes to utilize the recommendation of relational based therapy and whether implementation in the CMHC was feasible. A qualitative multiple case study design was utilized to collect personal interviews with 12 CMHC administrators who could discuss Norcross and Wampold's single recommendation about therapeutic relationships. Results were triangulated with the guide for CMHC financing, …

The Center For Total Health: Healthcare Reform In Cook County, Illinois, James Leon Miles

Walden Dissertations and Doctoral Studies

The Patient Protection and Affordable Care Act (PPACA) of 2010 requires hospital systems in the United States to shift the culture of patient care from a focus on sick-care to a focus on prevention and wellness care. Little is known about how hospital systems will make this culture shift while retaining quality patient care. The purpose of this case study of a pioneering hospital-based PPACA-compliant initiative was to answer the research question of how Wallace's revitalization movement theory (RMT) "a rapid culture change model"could serve as a transferable evaluation framework for PPACA prevention and wellness care compliance in hospital-based programs. …

The Deterrent Effect Of Disciplinary Segregation On Prison Inmate Misconduct, Joseph William Lucas

Walden Dissertations and Doctoral Studies

Although a widely used practice, it was previously unknown whether disciplinary segregation is actually effective at modifying prison behavior. This quantitative, retrospective observational study tested deterrence theory and explored the effectiveness of disciplinary segregation in deterring subsequent prison inmate misconduct among those subjected to it (N = 228). It compared a cohort of male inmates incarcerated by the Oregon Department of Corrections who had spent time in disciplinary segregation in 2011 and/or 2012 with a comparison cohort who had not spent any time in disciplinary segregation. Three models were tested, each with the outcome variable operationalized in a different way: …

The purpose of this study was to understand the dietary patterns associated with diabetes by comparing the relative adherence to these dietary patterns by individuals in 5 stages of diabetes: no diabetes, undiagnosed prediabetes, diagnosed prediabetes, undiagnosed diabetes, and diagnosed diabetes. Using the health belief model as the theoretical foundation, the primary research question examined whether adherence to specific dietary patterns significantly differed between individuals in different stages …

Skills Women Bring To The Position Of Chief Of Police, Jo-Ann Helen Savoie

Walden Dissertations and Doctoral Studies

Organizational leaders are unaware of the gender-specific leadership skillsets women possess to increase organizational effectiveness and how to address potential barriers for assuring these skillsets are recognized as effective. Of the estimated 69,000 police officers serving in Canada, approximately 14,000 are women. Of those 14,000, only 10% hold a senior rank, and less than 3% hold the position of Chief of Police. Technology speed, globalized crime, and shrinking budgets have created a need for a new style of leader in policing, and increasing the representation of women may address this need. This multiple case study used the concept of doing …

Exploring The Risk Factors That Influence The Parental Dental Deferment Decision, Megan White

Walden Dissertations and Doctoral Studies

When caregivers defer their personal routine dental care (RDC) in order to provide RDC for their children, they risk detrimental consequences in their personal health and the health of their children. The purpose of this qualitative case study was to identify the risk factors that led to the parental dental deferment decision. The oral health and personal care services conceptual models guided the development of the research questions, facilitated the selection of risk factors on the decision-making process, and provided the basis for the data analysis thematic categories.

Uric Acid Level Is Associated With Postprandial Lipemic Response To A High Saturated Fat Meal, Roy Gail Cutler

Walden Dissertations and Doctoral Studies

Hyperlipidemia caused by a diet high in saturated fat can lead to visceral fat weight gain, obesity, and metabolic syndrome. Being over-weight from visceral fat has been linked to increased risk of developing most age-related diseases and disability, along with a lower income potential and quality of life. However, researchers are just beginning to understand the biological mechanisms that regulate the conversion of excess calories into visceral fat storage rather than glycogen or muscle. Epidemiological studies have repeatedly shown a comorbid association between age-related diseases involving hyperlipemia and circulating levels of uric acid, but not a direct association. This study …

Influences Of Csi Effect, Daubert Ruling, And Nas Report On Forensic Science Practices, Timothy Patrick Scanlan

Walden Dissertations and Doctoral Studies

The media exaggerates the capabilities of crime laboratories while it publicizes the wrongdoings of individual forensic scientists. Such portrayals skew the perspectives of jurors and hinder expert witness testimony. Complicating the problem are separate, but related, phenomena that influence how forensic laboratories conduct casework. These phenomena are Cole and Dioso-Villa's conceptualization of the unrealistic expectations of forensic science created by fictional television, known as the CSI Effect; the Daubert ruling on the admissibility of expert testimony; and some federal policy changes as a result of a National Academy of Sciences (NAS) report that impacted requirements for the daily operation of …

A Study On The Relationship Between Emotional Intelligence And Mental Illness Stigma, E. Nicole Armstrong

Walden Dissertations and Doctoral Studies

Stigmatizing mental illness involves negative perceptions or attitudes about mental illness and the individuals who have mental illness, generating problematic consequences for both the general population and for people with mental illness. The theory of multiple intelligences proposes that intelligence includes skills and abilities in any area; emotional intelligence (EI), therefore, includes an individual's ability to identify, interpret, and regulate emotions and emotional responses. This study was designed to evaluate level of familiarity with mental illness as a potential predictor for stigmatizing mental illness, to assist in evaluating the relationship between stigmatizing mental illness and EI. The study was specifically …

The Healthy, Hunger-Free Kids Act And High School Obesity, Derek Grills

Walden Dissertations and Doctoral Studies

United States high school student obesity rates have doubled in the past 30 years to 13%, threatening the health of millions of adolescents. To mitigate the epidemic, Congress passed the Healthy, Hunger-Free Kids Act (HHFKA) in 2010, which mandated significant changes to school nutrition and physical education. From a public policy perspective, the HHFKA changed school nutrition and exercise policy to affect obesity rates by changing intake and energy expenditure at school, though no study using national-level data examined this relationship. As such, the purpose of the study was to examine whether HHFKA policy compliance had a statistically significant effect …

Lived Experiences Of Military Personnel Reintegrating With Their Preschool Aged Children, Rob Atchison

Walden Dissertations and Doctoral Studies

Researchers have indicated that school-aged children with a caregiver who had been deployed were more likely to exhibit emotional and behavioral problems. These problems were impacted by the ability of the parent at home to manage emotions so as to utilize appropriate parenting skills with the child. However, there remained an important gap in the literature regarding the experiences of the military personnel reintegrating with their preschool aged child. Therefore, the purpose of this phenomenological study was to address the experiences of military caregivers with their preschool-aged children through semistructured interviews to better understand the variables that impacted the ability …

Examining Behavioral Reactivity And Cognitive Differences Within The Chc Theory Of Intelligence Among Children., Steven Matthew Jozwiak

Walden Dissertations and Doctoral Studies

Linking cognition and behavior has long been an area of interest to the field of psychology in its endeavors to understand what innate factors influence human behavior. To date, the majority of research linking emotional reactivity to cognition has focused on single areas of intellectual functioning on specific diagnostic profiles or learning disorders rather than a comprehensive comparison to cognitive profile typology. Nearly all the research conducted to date continues to define cognition and emotion as disparate entities, rather than exploring a more integrated view of emotion and cognition. The purpose of this quantitative study was to examine cognitive profile …
