From field to home| Assessing air infiltration and soil track-in transport pathways of agricultural pesticides into farmworkers' home and identifying risk factors for increased in-home pesticide levelsSugeng, Anastasia Julia 07 June 2016 (has links)
<p> Farmworkers and their families may experience increased levels of agricultural pesticides in their homes due to both (1) take-home/soil track-in on shoes, clothes and skin, and (2) air infiltration from nearby agriculture fields via agricultural pesticide drift in the vapor phase or adhered to resuspended soil particles. This dissertation estimates the relative contributions o the take-home/soil track-in and air infiltration pathways of agricultural pesticides into homes, as well as identifies the risk factors for increased in-home agricultural pesticide levels for farmworkers and their families living near agriculture fields. Samples of outdoor air, yard soil, and house dust from 21 farmworkers' homes in Yuma County, Arizona were collected and analyzed for a suite of agricultural pesticides. To capture household information, such as behaviors, demographics, and housing structure, a participant questionnaire was administered at the time of the sampling. A pesticide transport model was developed, evaluated, and applied to quantify relative contributions of the air infiltration and the take-home/soil track-in pathways of agricultural pesticides into the house dust of the farmworkers’ homes. To explore a wide-range of potential risk factors for increased agricultural pesticide levels in the homes, traditional statistical methods and Classification and Regression Tree (CART) analyses were used. The results of this study, found that the air infiltration pathway contributes to over 90% of some agricultural pesticides in the house dust found in the farmworkers’ homes. In addition, among the influential risk factors for increased in-home agricultural pesticide levels was the home being a closer distance to an agricultural field, as well as the home having carpeted floors, more farmworkers per square footage of the home, and less months of heating and cooling the home. It is suggested that future intervention efforts to reduce in-home agricultural pesticide levels put more emphasis on targeting the air infiltration pathway, and take into consideration relevant risk factors for increased pesticide levels in the home.</p>

Experiences of ethnic microaggressions and cortisol reactivity to the Trier Social Stress Test in college studentsMajeno, Angelina 01 February 2017 (has links)
<p> Little is known about the impact of ethnic microaggressions (MA) on stress reactivity. The purpose of the current study was to examine how the frequency with which college students (<i>n</i> = 109) experience MA and their reactions to them relate to a biomarker of stress (i.e. salivary cortisol). Participants were exposed to the Trier Social Stress Test (TSST) and answered questions about the frequency of experiences of ethnic MA and their reaction to them (e.g. getting upset). Cortisol reactivity, cortisol recovery, and Area Under the Curve (AUC) were also assessed. Results of hierarchical regressions suggest that negative MA reactivity (i.e. getting upset) was associated with faster recovery and smaller AUC. Additionally, having high frequency of MA and high MA reactivity was associated with a blunted cortisol reactivity. Blunted cortisol responses may have negative health implications, as they have been associated to substance use, smoking, and obesity.</p><p>

Physical activity and mental healthBell, Edith M. 30 December 2016 (has links)
<p> The study investigated the relationship of physical activity (domain, frequency, amount, and intensity) on mental health (depression, stress, and anxiety) in the general population. Two hundred and fifty-three individuals eighteen or older completed either an online or paper survey for the study. Pearson Correlation, T-tests, and multiple regression were used in the data analysis. Results indicated vigorous activity correlated negatively with stress (<i>r</i> = -.16 <i>p</i> < .01) and anxiety, (<i> r</i> = -.15 <i>p</i> < .01). Amount of activity correlated negatively with anxiety, <i>r</i> = -.15 <i>p</i> < .05. Leisure time activity, frequency of activity, and amount of activity were significant predictors of stress among females, R<sup>2</sup> = .07, <i> p</i> < .05 and anxiety among males, R<sup>2</sup> = .09, <i> p</i> < .05 (vigorous for men and moderate for female). Males were found to participate in significantly more vigorous leisure activity than females, <i>t</i> = 2.50, <i>p</i> < .01. Given the limited research on factors of physical activity, results of the study offer useful information for future research into the complexities of physical activity and its effects on mental health.</p>

THE RELATIONSHIP BETWEEN BURNOUT AND THE SEMANTIC DIFFERENTIAL PROFILE OF EMPLOYEES OF A RESIDENTIAL FACILITY FOR DEVELOPMENTALLY DISABLED PERSONSUnknown Date (has links)
The intent of this research was to investigate the relationship between a measurement of burnout and semantic differential profiles involving personal and vocational life variables. Participants were employees of a residential facility for developmentally disabled persons. The statistical analysis was to involve the use of multiple linear regression for the null hypotheses and a judgmental evaluation was to be utilized for determining levels of differences between burnout and semantic profiles. / A pilot study was completed to investigate potential problems existing in the administration and in response to two questionnaires (burnout and semantic differential profile). Corrections were made prior to administration to the primary research facility. / From the primary research administration, a total of 250 questionnaires were returned. A sample size of 169 was predetermined as adequate for use of the multiple linear regression anaylsis. However, only 81 responses were adequate in terms of completed questionnaire items. The limited responses prevented the anticipated analysis at the statistical levels prespecified. A follow-up interview with the participants revealed problems with reading comprehension and a defensive attitude about this research effort. A review of the demographic data suggested different descriptive factors between the 81 respondents and the 169 nonrespondents. / The results provided were limited to descriptive data which reflected research findings of the applicable literature review and provided impetus for this research experience; the results also offer indications for modifications in administration and future replications of this research effort. / Source: Dissertation Abstracts International, Volume: 45-08, Section: B, page: 2495. / Thesis (Ph.D.)--The Florida State University, 1984.

Climate Change, Human Health, and the Doctor-patient RelationshipAli, Diala 12 April 2019 (has links)
<p> Climate change has become responsible for substantial mortality and morbidity around the world. These numbers are said to rise, as climate change will continue to have both direct and indirect effects on human health, as well as threaten the determinants of health. Some health effects include asthma, respiratory disease, cancer, cardiovascular disease, stroke, health-related illness, human developmental effects, mental illness, neurological disease, vector-borne disease, waterborne disease, and more. Given the implications it carries on human health, climate change should be of fundamental relevance to doctors and future doctors alike. The aim of this thesis is to explore the importance of preparing doctors and student doctors for a climate-changing world. This includes developing skills and insights necessary in a clinical practice and a public health role. The research methods in this thesis is sought to identify if future doctors are being prepared and are willing to take action against climate change and the health implications it poses. The focus is also to identify the perceptions of doctors on climate change and its health risks, as little is known about this. Through theoretical and quantitative evidence, the goal is to provide insight on the role future doctors, who are both prepared and willing to take actions, can play in influencing patients to participate in climate change mitigation.</p><p>
