Les circulations atmosphériques synoptiques et locales expliquent les variabilités spatiotemporelles des précipitations en Amazonie brésilienne. Ce vaste espace géographique est caractérisé par un réseau pluviométrique peu dense et hétérogène qui limite un suivi exhaustif des pluies. La télédétection est alors l'outil préférentiel afin de pallier cette lacune spatiale. Toutefois, les estimations quantitatives des précipitations (QPE) dérivées des domaines spectraux des infrarouges (IR) et Micro-ondes (MO), ou de techniques multi canaux souffrent d'erreurs. Les sources d'incertitudes et biais des QPE peuvent provenir de la calibration des capteurs, de l'algorithmie et de l'échantillonnage des champs de pluie. Dans cette thèse, l'évaluation des algorithmes TRMM3B42(v6), CMORPH et PERSIANN s'appuie sur une base de données pluviométriques dont la fiabilité est assurée par un contrôle de qualité rigoureux. Sur la période 2003-2009, l'inter comparaison des produits satellitaires montre un faible accord (coefficient de détermination < 0,30) avec la base de référence en Amazonie brésilienne Légale. TRMM3B42(v6) présente la meilleure performance avec un échantillonnage correct des champs de pluie. En outre, un cas d'études montre que les erreurs des QPE par satellite sont plus importantes en milieu forestier, notamment pour le produit MO MWCOMB. Enfin, la correction des grilles satellitaires par PDF Matching permet de réaliser une analyse climatologique approfondie et améliorée par rapport à la base de référence

The main objective of this thesis is to analyse if and to what extent changes in the labour market can be regarded as a factor influencing the risk of becoming a disabil­ity pensioner. Disability pension is a social security program operating in the nexus of work and welfare and is provided to people who, due to medical reasons, are limited in their work ability. The data material analysed consists of information about all individuals who received disability pension in 1988 (54 000) and 1993 (62 000) in Sweden. Samples fremi the non-pensioner population formed control- groups. The data collected covers mainly social and occupational background of the individuals. The first step in the analyses addressed the question of causes of disability pen­sion in general. This part showed that the causes must be seen in a multifactorial perspective. Individual, structural and institutional factors have significant impact on the relative risk of becoming a disability pensioner. An increased relative risk was associated with low educational background, immigration and broken marriages. However, the variables that had the strongest effect were age, health and position in the labour market i.e. social class and occupation. It became obvious that one im­portant mechanism explaining the impact of occupation was exposition of work environment conditions. The second step in the analyses focused on labour market change as a risk-factor. The results showed a negative correlation between employment change rates and disability pension. Individuals in occupations and industries with decreasing num­ber of emplyoees had an increased relative risk. It became clear that especially un­skilled workers and employees with a peripheral position were affected by this factor. This was especially true for women. The female labour market is to a large extent dependent on the public service sector and the reductions within this sector have resulted in an increased frequency of disability pensioning. To conclude, the study has shown that disability pension in Sweden is deeply embedded in the labour market and the occupational structure in Sweden. This can be explained both as a consequence of characteristics that accompany certain posi­tions at the labour market and as an effect of how the labour market develops. / digitalisering@umu

The beginning of this study is from sociology of occupations and depends on various viewpoints of functionalism, postmodernism, exchange theory and motivation theory to discuss the developing processes of professionalism and the licensure in the modern society; moreover, to reorganize all different kinds of views to the licensure. Secondly, researchers explain differences of the licensure and social work licensure of each country from America, Japan, Taiwan, and Hong Kong etc. In addition, according to the literature review result, it affects external environmental factors of carrying out Taiwan social work license system and describes developing veins of Taiwan social work licensure. The study is through the qualitative research methods of interviews guide and focused group. Collecting all information of twenty-two social service workers to attitude of the social work licensure in southern Taiwan, and from the data we can conclude that we can offer to social workers a stigma or the glory from the social license examination. Besides, we also can provide function or anti-function, and an order or disorder of the social work license. Furthermore, the examination and teaching which is the first step of the social work licensure or in the educational field. Moreover, the impact or a response and a transition or an existence of the social work license examination and practical field. Professionalization or deprofessionalization of the social work license, starting or re-starting of the professional association, and working circumstances or labor conditions of the social work licensure and professional organization. In terms of the conclusion, researchers provide suggestions differently to ministry of examination, practical field, educational field and specialized association.

Cancer is devastating. Medical advances have resulted in the ability to diagnose cancer at its earliest stages and increase survivorship. Unfortunately, Black Americans possess a disproportionate cancer burden, with the highest mortality and lowest survival rate of any racial/ethnic group. Lung cancer is the most deadly, yet most treatable cancer. The purpose of this study was to determine the impact that the healthcare education program had on healthcare students’ level of cultural development and awareness of disparities regarding Black Americans and tobacco cessation. In light of the data substantiating that health disparities stem from a combination of racial and ethnic inequities in the access of the healthcare system, healthcare professionals’ low levels of cultural development, and the missed opportunities for promoting Black American tobacco cessation, the following questions were developed to frame the research: Research Question #1: How will the level of healthcare students’ cultural development change as a result of a healthcare education program? This question corresponds to the following hypotheses being tested in this study: Methods to answer this question included evaluation of findings from 1) comparison of pre and post-program Inventory for Assessing the Process of Cultural Competence Among Healthcare Professionals – Revised (IAPCC-R) mean scores by degree of study and by gender; and 3) comparison of pre and post-program Tobacco Cessation Assessment (TCA) mean scores by degree of study and by gender. Research Question #2: What is the relationship between cultural competence and increased awareness of disparities regarding Black Americans and tobacco cessation? Methods utilized to answer this question included evaluation of findings from comparison of results of knowledge gains in TCA vs. IAPCC-R mean scores, including using the Pearson’s correlation coefficient to determine existence and strength of the relationship. Findings were 1) level of cultural development increased; 2) awareness of disparities regarding Black Americans and tobacco cessation increased; and 3) weak, but statistically significant relationship between higher level of cultural development and increased awareness of disparities regarding Black Americans and tobacco cessation. This study could serve as a model for future partnerships with researchers, faculty, and healthcare professionals, linking pre-profession preparation with continuing professional education. / Department of Educational Studies

The paper examines the extent to which the prestige value of a retiree’s former occupation increases the likelihood that they will make a transition into volunteering after retirement. Following social production function theory, we assume that when a person retires, the prestige value attached to their former occupation fades. The fact that volunteering has the character of a collective good provides the opportunity to gain social prestige to offset the loss of occupational prestige. However, the extent of the incentive to volunteer will be distributed unequally across occupations: the higher the former occupational prestige value, the higher the perceived loss of prestige after retirement. Thus, doing a job with high prestige value increases the incentive to volunteer in retirement. This assumption is tested, using data taken from the German Socio-Economic Panel (GSOEP) 1992-2013. The sample contains 1,631 workers and 589 retirees, 278 of whom transitioned into volunteering during the observation window. Based on Kaplan-Meier-Failure-Estimates and complementary log-log hazard models, findings show a positive effect of occupational prestige on the transition into volunteering. Thus, the loss of high occupational prestige can be compensated by the social prestige associated with volunteering. Formal volunteering in retirement follows, albeit to a lesser extent, the logic of the occupational social strata.

Low back pain (LBP) remains one of the most common and challenging primary care issues in the developed world. Manual occupations such as nursing are known to involve a high risk of occupational LBP, which is associated with enormous health care expenditure as well as indirect work and disability-related costs. Despite extensive efforts to reduce LBP in nurses, evidence supporting the efficacy of any specific intervention to prevent LBP is limited. / The majority of LBP prevention strategies are directed at occupational risk factors in working nurses. However, as there is some evidence that LBP is already a significant problem in nurses prior to commencing full time employment, it is proposed that nursing students should be the focus of prevention interventions. This would require prevention interventions targeting personal rather than occupational LBP risk factors. As the best personal predictor of future LBP is currently a previous history of LBP, further investigation of modifiable personal LBP risk factors is required. Consequently, the aim of this doctoral research was to identify modifiable personal characteristics that predict LBP in nursing students. / Firstly, a large survey was conducted on undergraduate nursing students and recently graduated nurses to determine patterns of LBP prevalence. Results from this study indicated that LBP prevalence was very high at the commencement of undergraduate training. Prevalence of LBP did not significantly change during nursing training, but did increase further in the first year of commencing work as a nurse. This increase may be partly explained by the reported increase in occupational exposure to bending and lifting. Age was consistent across the undergraduate year groups and did not influence these findings. It was concluded that nursing students would provide a sufficient number of new-onset LBP episodes (and thus sufficient statistical power) for a prospective study design. Further, as these nursing students were not yet exposed to the occupational LBP risk factors of working nurses, a clearer indication of the influence of modifiable personal factors on the development of LBP could be determined by examining a student cohort. / A cross-sectional study investigating the influence of personal physical, psychological and social/lifestyle factors was then conducted on nursing students. Preliminary analysis revealed clear gender differences across multiple domains. Therefore, the focus of further analysis was on the larger female sample. / In Part 1 of the cross-sectional study, an investigation of regional differences in lumbar spine posture and movement was undertaken. Analysis of spinal kinematics in this study supported and extended previous literature that has found global lumbar spine kinematics do not accurately reflect the kinematics of the upper lumbar or lower lumbar spinal regions in common postures and movements. Rather, these two regions have a degree of functional independence. This finding has implications for interpretation of measures of spinal posture, motion and loading. Further, body mass index influenced regional lumbar posture and movement, possibly representing adaptation due to load. It was concluded that regional rather than global lumbar spine measures needed to be investigated in further analyses of this doctoral research. / In Part 2 of the cross-sectional study, personal characteristics associated with LBP were investigated. Approximately one third of all subjects reported significant LBP in the 12-months preceding the study. Analysis of factors associated with LBP supported the biopsychosocial nature of LBP. Higher stress levels and use of passive coping strategies, increased physical activity levels, holding the lower lumbar spine further from end-range flexion during functional tasks and increased age, all contributed independently to the presence of LBP. These findings supported the hypothesis that modifiable personal characteristics were associated with LBP. / The importance of identifying sub-groups of LBP patients has become widely accepted. In Part 3, further exploratory analysis was conducted on this crosssectional data to determine if differences in physical and psychological characteristics were evident in two defined sub-groups of female nursing students with LBP. These sub-groups were based on O’Sullivan’s mechanism based classification system. Results indicated that two sub-groups of LBP subjects had differing physical and psychological characteristics associated with their LBP. Further, control subjects could be distinguished from each of these two sub-groups by different factors. These findings add validity to O’Sullivan’s LBP classification system. Further, the findings may suggest that different combinations of psychological and physical factors are linked to LBP in different sub-groups in this population, and therefore may require different intervention approaches based on these factors. / In the final stage of this doctoral research, the cohort of female nursing students was followed prospectively for 12-months. The focus of further analysis was on identifying modifiable personal predictors in a sub-group of subjects with new-onset LBP. The results of this study strongly supported that personal factors from multiple domains are predictors of new-onset LBP. After controlling for previous LBP, age and body weight, regression analysis identified that smoking, increased physical activity levels (both exercise and spinal loading), higher stress levels, reduced back muscle endurance, greater posterior pelvic tilt in slump sitting and more accurate spinal repositioning in sitting were all independent predictors of new-onset LBP. These findings have implications for the development of prevention and management interventions for LBP in nurses. / Results from this doctoral investigation support the multi-factorial and biopsychosocial nature of LBP. The important distinction of this research when compared to previous work is the selection of a cohort at the beginning of their working life, with a focus on modifiable personal, rather than occupational factors, associated with LBP. Factors from physical, psychological and social/lifestyle domains were all independently associated with significant new-onset LBP in female nursing students. Interventions utilising a prevention approach that targets modifiable characteristics, such as those identified in this cohort of nursing students, may have the potential to reduce the impact of occupational LBP in this group. These preliminary findings have important implications for future LBP research and clinical interventions.
