Farm Deaths And Injuries: Changing Farmer Attitudes And Behaviour On Farm Safety, Kieran O'Connell Jan 2017

Farm Deaths And Injuries: Changing Farmer Attitudes And Behaviour On Farm Safety, Kieran O'Connell

Theses

While the Irish agricultural sector accounts for just 6% of the working population of Ireland, it consistently has the highest proportion of fatal incidents of any sector - generally ranging from between 35% and 45% of all workplace fatalities in any given year (Health and Safety Authority, 2015). This was again evident in 2014 where 55% (30 of the 56) of the fatal workplace incidents were in the agricultural sector (Health and Safety Authority, 2015). Agriculture has an ageing workforce with the average age of an Irish farmer now standing at fifty-seven and farmers are eight times more likely to …

Assisted Suicide, Valerie Ontiveros Jan 2017

Assisted Suicide, Valerie Ontiveros

Nebraska College Preparatory Academy: Senior Capstone Projects

Assisted suicide is when a physician helps a terminally ill patient die without pain. As of right now, it is illegal in most states. Organizations about this issue were organized in the late 1930's (Humphry). According to Pro-Con. Org, 79% of patients requested assisted suicide even before they came terminally ill –if it got to that point.

Many states have different laws on assisted suicide. In no doubt, these patients go through a tremendous amount of pain and no one but themselves should decide when enough is enough. Technological advances have allowed this generation to help aid a person when …

Poison In Pink, Sydney V. Cook

Graduate Student Theses, Dissertations, & Professional Papers

Humans slather, spray, mist, and cleanse their bodies with personal care products like lotion, hairspray, cologne, and shampoo every day. Our cupboards are stocked full of them, but few of us understand what is in those jars and bottles. We trust that if it’s on the shelf at the store, it’s safe. However, this is not always the case, and many personal care products contain chemicals that are harmful to human and environmental health.

My multi-disciplinary Environmental Studies thesis project combines evidenced-based research, interviews, nonfiction narrative, and science communication to create part of a book manuscript intended to educate general …

Self-Reported Adherence To Physical Activity For Cancer Survivors: An Update From The 2015 Nhis Database, Andrew Jackson Shearer

Theses and Dissertations--Kinesiology and Health Promotion

Cancer is the second leading cause of death in America. It’s been suggested that regular physical activity (PA) can improve health outcomes in cancer survivors. An estimate from BRFSS data (2009) suggested that 47% of all cancer survivors met recommended guidelines and that this estimate was not different from the population at large (48%). Several factors were examined from these BRFSS data to determine whether subgroups of survivors existed who might benefit from interventions aimed at improving their PA status. The purpose of this investigation was to obtain more recent estimates of adherence to established PA guidelines for cancer survivors. …

Equestrian sport is a popular exercise choice for females of all ages, although the links between this exercise choice, health outcomes, and risk to health have not been thoroughly examined. These issues are of particular interest because the female equestrian has the opportunity to ride and/or compete for decades, from early to very late in life, covering almost the full sequence of the female lifespan. Equestrian sports provide physical activity through riding and caring for the horse, and promote positive mental outcomes through tangible practices, such as engaging in physical activity and hard work, goal-setting, acquisition of skills, and participation …


Statistical Analyses To Detect And Refine Genetic Associations With Neurodegenerative Diseases, Yuriko Katsumata Jan 2017

Statistical Analyses To Detect And Refine Genetic Associations With Neurodegenerative Diseases, Yuriko Katsumata

Theses and Dissertations--Epidemiology and Biostatistics

Dementia is a clinical state caused by neurodegeneration and characterized by a loss of function in cognitive domains and behavior. Alzheimer’s disease (AD) is the most common form of dementia. Although the amyloid β (Aβ) protein and hyperphosphorylated tau aggregates in the brain are considered to be the key pathological hallmarks of AD, the exact cause of AD is yet to be identified. In addition, clinical diagnoses of AD can be error prone. Many previous studies have compared the clinical diagnosis of AD against the gold standard of autopsy confirmation and shown substantial AD misdiagnosis Hippocampal sclerosis of aging (HS-Aging) …


Evaluation Of Pyriproxyfen Applied In Barrier Sprays For Mosquito Suppression, Andrea Glenn Skiles Jan 2017

Evaluation Of Pyriproxyfen Applied In Barrier Sprays For Mosquito Suppression, Andrea Glenn Skiles

Theses and Dissertations--Entomology

Despite advances in mosquito management, mosquito-borne disease in the United States is still of relevant public health concern and vector control is a top priority in preventing transmission of pathogens. Insecticide barrier sprays have become a common tool for suppression of mosquitoes in single-homeowner backyards. The application of the synthetic pyrethroid, lambda-cyhalothrin to perimeter vegetation with a backpack sprayer has been shown to significantly suppress mosquito levels for around 6 weeks. In an attempt to lengthen the effective duration of treatment, the IGR, pyriproxyfen, was added to a backpack mist blower with lambda-cyhalothrin, as adult mosquitoes exposed to pyriproxyfen have …

Development Of The Meal Framework: A Multiliteracies Approach To Engaging Adolescents In Nutrition Education, Samantha Lee Baker

Theses: Doctorates and Masters

Establishing and maintaining a healthy diet is integral in promoting optimal health, growth and development. Moreover, the food choices we make and dietary behaviours we adopt are a reflection of the multiple personal, interpersonal and environmental factors to which we are exposed. Consequently, changing food habits and dietary behaviour is complex and requires the implementation of multifaceted public health strategies. Comprehensive nutrition education provided to adolescents during their school years is one such approach.

Adolescence is a period of rapid psychological and physiological changes. At a socioemotional level, there is a decreased level of dependence on parents and a greater …

Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts Jan 2017

Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts

Williams Honors College, Honors Research Projects

Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.

Objectives: To evaluate the use of biomarkers in children seen in the Emergency …

Clinicopathology And Molecular Determinants Underlying Benign Breast And Breast Cancer Lesions, Andreana Holowatyj Holowatyj

Wayne State University Dissertations

Despite converging incidence rates for breast cancers by race, disparities in mortality persist where black women suffer from poorer prognosis compared to white counterparts. To understand the clinical, demographic, and molecular characteristics underlying these disparities, we examined differences among patients with breast cancer to understand the role of human epidermal growth factor receptor 2 (HER2) status, age, and race/ethnicity among women diagnosed with hormone receptor-positive breast cancer, and disparities in surgical therapy among female patients with early stage young-onset breast cancer. Benign breast disease, another known risk factor for breast cancer, includes a histological spectrum of lesions, could contribute to …


Using Multi-Theory Model To Predict Low Salt Intake - Nigerian Adults With Hypertension, Christine Adekemi Dokun-Mowete Jan 2017

Using Multi-Theory Model To Predict Low Salt Intake - Nigerian Adults With Hypertension, Christine Adekemi Dokun-Mowete

Walden Dissertations and Doctoral Studies

Hypertension is a chronic non-communicable disease and a major risk factor for cardiovascular diseases, renal malfunction, disability, and premature death. One of the public health recommendations for the management of hypertension is the reduction of sodium/salt intake. There is need to develop and implement new evidence-based theoretical interventions to initiate and sustain behavior change in health education and promotion. Therefore, the quantitative cross-sectional method and design was used to investigate the adequacy of multi-theory model (MTM) constructs for the initiation and the sustenance of low sodium/salt intake behavior in hypertensive Nigerian adults. In addition, the impact of the MTM (initiation) …
