The aims of this thesis were to determine the animal health status in organic dairy farms in Europe and to identify drivers for improving the current situation by means of a systemic approach. Prevalences of production diseases were determined in 192 herds in Germany, France, Spain, and Sweden (Paper I), and stakeholder consultations were performed to investigate potential drivers to improve animal health on the sector level (ibid.). Interactions between farm variables were assessed through impact analysis and evaluated to identify general system behaviour and classify components according to their outgoing and incoming impacts (Paper II-III). The mean values and variances of prevalences indicate that the common rules of organic dairy farming in Europe do not result in consistently low levels of production diseases. Stakeholders deemed it necessary to improve the current status and were generally in favour of establishing thresholds for the prevalence of production diseases in organic dairy herds as well as taking actions to improve farms below that threshold. In order to close the gap between the organic principle of health and the organic farming practice, there is the need to formulate a common objective of good animal health and to install instruments to ensure and prove that the aim is followed by all dairy farmers in Europe who sell their products under the organic label. Regular monitoring and evaluation of herd health performance based on reference values are considered preconditions for identifying farms not reaching the target and thus in need of improvement. Graph-based impact analysis was shown to be a suitable method for modeling and evaluating the manifold interactions between farm factors and for identifying the most influential components on the farm level taking into account direct and indirect impacts as well as impact strengths. Variables likely to affect the system as a whole, and the prevalence of production diseases in particular, varied largely between farms despite some general tendencies. This finding reflects the diversity of farm systems and underlines the importance of applying systemic approaches in health management. Reducing the complexity of farm systems and indicating farm-specific drivers, i.e. areas in a farm, where changes will have a large impact, the presented approach has the potential to complement and enrich current advisory practice and to support farmers’ decision-making in terms of animal health.

Signifying road-related events with warnings can be highly beneficial, especially when imminent attention is needed. This thesis describes how modality, urgency and situation can influence driver responses to multimodal displays used as warnings. These displays utilise all combinations of audio, visual and tactile modalities, reflecting different urgency levels. In this way, a new rich set of cues is designed, conveying information multimodally, to enhance reactions during driving, which is a highly visual task. The importance of the signified events to driving is reflected in the warnings, and safety-critical or non-critical situations are communicated through the cues. Novel warning designs are considered, using both abstract displays, with no semantic association to the signified event, and language-based ones, using speech. These two cue designs are compared, to discover their strengths and weaknesses as car alerts. The situations in which the new cues are delivered are varied, by simulating both critical and non-critical events and both manual and autonomous car scenarios. A novel set of guidelines for using multimodal driver displays is finally provided, considering the modalities utilised, the urgency signified, and the situation simulated.

Introducción Los lugares de trabajo contribuyen al bienestar del individuo y en algunos casos pueden constituirse en factores que llevan a alteraciones en la condición de salud. Los trabajadores pueden estar predispuestos a algún tipo de desórdenes musculo-esqueléticos que se generan durante la jornada laboral creando molestia y algunas veces estar asociados a factores de riesgo psicosocial. Objetivo Establecer la relación entre los factores de riesgo psicosocial con síntomas músculo-esqueléticos en trabajadores vinculados a una empresa social del estado Bogotá, 2014. Métodos Se realizó un estudio de corte transversal en una muestra de 203 trabajadores. Como instrumentos se utilizó la Batería de riesgo psicosocial y cuestionario Nórdico. Se realizó análisis estadístico empleando medidas de tendencia central y de dispersión y se midieron asociaciones con el fin de conocer las variables que se relacionan con el evento. Se manejó el programa estadístico SPSS 20 para Windows. Resultados El 78,8% de los trabajadores correspondieron al sexo femenino, con una edad media de 38 ±10,28 años. El promedio de años de antigüedad dentro de la empresa fue de 3,9 ±,6553, se encontró que el 90.4% están expuestos a factores psicosocial extra laborales con clasificación de riesgo despreciable y el 91,6% a factores intralaboral con clasificación de riesgo muy alto. Se encontró prevalencia de sintomatología musculo esquelética a nivel de cuello con un 70%, dorso lumbar con el 56,2%, mano o muñeca el 54,7% y hombro con el 51,7%. Se encontró diferencia significativa entre el dominio de demandas del trabajo con síntomas presentes en hombro y mano/muñeca (p<0,05), seguido de las dimensiones de control sobre el trabajo con síntomas en hombro (p<0,05). Conclusiones La población estudiada presento una elevada prevalencia de síntomas musculo esqueléticos y un alto riesgo psicosocial intralaboral probablemente debido a características del trabajo y de su organización que influyen en la salud y bienestar del individuo.

This study analyzes the impact of individual characteristics as well as occupation and industry on male wage inequality in nine European countries. Unlike previous studies, we consider regression models for five inequality measures and employ the recentered influence function regression method proposed by Firpo et al. (2009) to test directly the influence of covariates on inequality. We conclude that there is heterogeneity in the effects of covariates on inequality across countries and throughout wage distribution. Heterogeneity among countries is more evident in education and experience whereas occupation and industry characteristics as well as holding a supervisory position reveal more similar effects. Our results are compatible with the skill biased technological change, rapid rise in the integration of trade and financial markets as well as explanations related to the increase of the remunerative package of top executives.

It has been estimated that one third of edible food destined for human consumption is lost or wasted along the food supply chain globally. Much of the waste comes from Global North, where consumers are considered as the bigger contributors. Different studies tried to analyze and estimate the Household Food Waste (HFW), especially in UK and Northern Europe. The result is that accurate studies at national level exist only in UK, Finland and Norway while no such studies are available in Italy, except for survey- based researches. Though, there is a widespread awareness that such methods might be not able to estimate Food Waste. Results emerging from literature clearly suggest that survey estimate inferior amounts of Food Waste as a result, if compared to waste sorting and weighting analysis or to diary studies. The hypothesis that household food waste is under-estimated when gathered through questionnaires has been enquired into. First, a literature review of behavioral economics and heuristics has been proposed; then, a literature review of the sector listing the existing methodologies to gather national data on Household Food Waste has been illustrated. Finally, a pilot experiment to test a mixed methodology is proposed. While literature suggests that four specific cognitive biases might be able to affect the reliability of answers in questionnaires, results of the present experiment clearly indicate that there is a relevant difference between how much the individual thinks to waste and he/she actually does. The result is a mixed methodology based on questionnaire, diary and waste sorting, able to overcome the cons of each single method.

Atmospheric carbon dioxide records indicate that the land surface has acted as a strong global carbon sink over recent decades, with a substantial fraction of this sink probably located in the tropics, particularly in the Amazon. Nevertheless, it is unclear how the terrestrial carbon sink will evolve as climate and atmospheric composition continue to change. Here we analyse the historical evolution of the biomass dynamics of the Amazon rainforest over three decades using a distributed network of 321 plots. While this analysis confirms that Amazon forests have acted as a long-term net biomass sink, we find a long-term decreasing trend of carbon accumulation. Rates of net increase in above-ground biomass declined by one-third during the past decade compared to the 1990s. This is a consequence of growth rate increases levelling off recently, while biomass mortality persistently increased throughout, leading to a shortening of carbon residence times. Potential drivers for the mortality increase include greater climate variability, and feedbacks of faster growth on mortality, resulting in shortened tree longevity. The observed decline of the Amazon sink diverges markedly from the recent increase in terrestrial carbon uptake at the global scale, and is contrary to expectations based on models.

This aim of this work was to carry out an epidemiological study on acetabular fractures in the city of Campinas and surrounds, in view of the few published papers on this subject. Medical files with a diagnosis of acetabular fracture between the years 2004 and 2008 that were made available by the Medical Archiving Service of Hospital das Clínicas, State University of Campinas (UNICAMP) were analyzed by six observers. Data on patients' ages, sex, side affected by the fracture, mechanism of injury, material used for synthesis, complications of the operation, associated fractures, length of hospitalization before and after the surgery, time of total internment and number of physiotherapy sessions before and after the surgery were gathered. It was observed in this population that the left side was more affected; the mechanism of injury that most often caused this type of fracture was automobile accidents; injuries to the sciatic nerve were the commonest surgical complications; and the synthesis material most used was reconstruction plates.

OBJETIVO: Comparar dados pré-natais, dos partos e dos recém-nascidos de Campinas em 2001 e 2005. MÉTODOS: Estudo transversal que analisou 13.656 documentos do Sistema de Informações sobre Nascidos Vivos (Sinasc) de 2005, comparando-as aos resultados de 2001. Analisou-se o local de moradia e parto, idade materna, estado civil, escolaridade, ocupação, paridade, consultas de pré-natal, tipo de parto, duração da gestação e peso ao nascer. Para avaliar a associação entre as variáveis, utilizou-se o teste de qui-quadrado, sendo significante p<0,05. RESULTADOS: Os nascidos nos Distritos de Saúde (DS) com piores índices de condições de vida (ICV) diminuíram em relação a 2001. A taxa de adolescentes passou de 17,7% para 14,7%. Em 2001, 39,4% das mães trabalhavam e, em 2005, 42,9%. Quanto à presença de companheiro, 35,9 e 54,3% não o referiam em 2001 e 2005, respectivamente. A escolaridade passou de 37,8% de mães com até sete anos de estudo para 25,7%, com aumento das que estudaram entre oito e 11 anos e 12 anos ou mais. O comparecimento a mais de seis consultas no pré-natal passou de 74,4 para 86,6%. Houve aumento de cesáreas (54,9 para 60,3%) e de prematuridade (7,1 para 8,9%). Não houve alteração no perfil de peso ao nascimento. CONCLUSÕES: Verificou-se queda da paridade nos DS com piores ICV e no percentual de mães adolescentes. Elevou-se o número de trabalhadoras, mulheres sem companheiro, escolaridade e frequência ao pré-natal.

OBJETIVO: Descrever opiniões e atitudes sobre sexualidade da população urbana brasileira. MÉTODOS: Inquérito de base populacional realizado em 2005, em amostra representativa de 5.040 entrevistados. Realizou-se análise das atitudes diante da iniciação e educação sexual de adolescentes, considerando sexo, idade, escolaridade, renda, estado civil, religião, cor, região geográfica e opiniões sobre fidelidade, homossexualidade e masturbação. Os resultados foram contrastados com pesquisa similar realizada em 1998, sempre que possível. RESULTADOS: A maioria dos entrevistados escolheu como significado para o sexo a alternativa: "sexo é uma prova de amor". Como em 1998, a maioria manifestou-se pela iniciação sexual dos jovens depois do casamento (63,9% para iniciação feminina vs. 52,4% para a masculina), com diferenças entre praticantes das diversas religiões. A educação escolar de adolescentes sobre o uso do preservativo foi apoiada por 97% dos entrevistados, de todos os grupos sociais. Foi elevada a proporção de brasileiros que concordaram com o acesso ao preservativo nos serviços de saúde (95%) e na escola (83,6%). A fidelidade permaneceu um valor quase unânime e aumentou, em 2005, a proporção dos favoráveis à iniciação sexual depois do casamento, assim como a aceitação da masturbação e da homossexualidade, em relação à pesquisa de 1998. As gerações mais novas tendem a ser mais tolerantes e igualitárias. CONCLUSÕES: Como observado em outros países, confirma-se a dificuldade de estabelecer uma dimensão única que explique a regulação da vida sexual ("liberal" vs "conservador"). Sugere-se que a normatividade relativa à atividade sexual deva ser compreendidas à luz da cultura e organização social da sexualidade ao nível local, auscultadas pelos programas de DST/Aids. A opinião favorável ao acesso livre ao preservativo na escola contrasta com resultados mais lentos no âmbito do combate ao estigma e à discriminação das minorias homossexuais. A formulação de políticas laicas dedicadas à sexualidade permitirá o diálogo entre diferentes perspectivas.

Sediment cores are an essential tool for the analysis of the dynamics of mangrove succession. Coring was used to correlate changes in depositional environments and lateral sedimentary facies with discrete stages of forest succession at the Cananéia-Iguape Coastal System in southeastern Brazil. A local level successional pattern was examined based on four core series T1) a sediment bank; T2) a smooth cordgrass Spartina alterniflora bank; T3) an active mangrove progradation fringe dominated by Laguncularia racemosa, and; T4) a mature mangrove forest dominated by Avicennia schaueriana. Cores were macroscopically described in terms of color, texture, sedimentary structure and organic components. The base of all cores exhibited a similar pattern suggesting common vertical progressive changes in depositional conditions and subsequent successional colonization pattern throughout the forest. The progradation zone is an exposed bank, colonized by S. alterniflora. L. racemosa, replaces S. alterniflora as progradation takes place. As the substrate consolidates A. schaueriana replaces L. racemosa and attains the greatest structural development in the mature forest. Cores collected within the A. schaueriana dominated stand contained S. alterniflora fragments near the base, confirming that a smooth cordgrass habitat characterized the establishment and early seral stages. Cores provide a reliable approach to describe local-level successional sequences in dynamic settings subject to drivers operating on multiple temporal and spatial scales where spatial heterogeneity can lead to multiple equilibria and where similar successional end-points may be reached through convergent paths.

O objetivo foi analisar o perfil dos recém-nascidos, mães e mortalidade neonatal precoce, segundo complexidade do hospital e vínculo com o Sistema Único de Saúde (SUS), na Região Metropolitana de São Paulo, Brasil. Estudo baseado em dados de nascidos vivos, óbitos e cadastro de hospitais. Para obter a tipologia de complexidade e o perfil da clientela, empregaram-se análise fatorial e de clusters. O SUS atende mais recém-nascidos de risco e mães com baixa escolaridade, pré-natal insuficiente e adolescentes. A probabilidade de morte neonatal precoce foi 5,6‰ nascidos vivos (65% maior no SUS), sem diferenças por nível de complexidade do hospital, exceto nos de altíssima (SUS) e média (não-SUS) complexidade. O diferencial de mortalidade neonatal precoce entre as duas redes é menor no grupo de recém-nascidos < 1.500g (22%), entretanto, a taxa é 131% mais elevada no SUS para os recém-nascidos > 2.500g. Há uma concentração de nascimentos de alto risco na rede SUS, contudo a diferença de mortalidade neonatal precoce entre a rede SUS e não-SUS é menor nesse grupo de recém-nascidos. Novos estudos são necessários para compreender melhor a elevada mortalidade de recém-nascidos > 2.500g no SUS.
