Based on oral histories of agriculture and health in the Mae Chaem valley, northern Thailand, this work documents changing child health and medical practice since the 1950's and explores possible connections with increasing pesticide use. The research shows how local knowledge can help us understand relationships between changing technology, ecology, and human health. Parents and farmers in the Mae Chaem valley of Chiang Mai province, Northern Thailand, live at the intersection of multiple local and global streams of land use and child health biotechnology. Based on systematically collected autobiographical oral histories from parents and farmers, as well as interviews and participant observation with land use and child health experts the study considers the relationships between child health and land use change, and particularly the rise of pesticide intensive cash cropping, since the late 1950’s. Introductory chapters on theory and methods precede a description of the ethnographic context. Case studies illustrating parent and farmer histories of child health and land use change spanning fifty years are provided. Seven streams of biotechnical expertise are identified, and mini-ethnographies are provided for each including domestic, Buddhist, Muang, spirit, market, national, and Christian. These seven streams are analyzed using actor-network theory (ANT) with relationships to particular notions of ontology, cosmology, and ecology. Results demonstrate the ongoing importance of parents and farmers as decision making agents at the intersection of multiple and competing cultural and biotechnical streams, even where they face efforts by large multinational corporations or other agencies to advertise, constrain and monopolize local biotechnical choice. Within the fifty year time period under consideration, the oral histories describe particular child health and land use trends. These locally perceived trends provide challenging perspectives on the relationship between ‘development’ and child health in Thailand. While children die far less often now than in the past, oral histories suggest that both children and fields now suffer from more kinds of illness, and more often, than before. In particular, both qualitative and more quantitative analysis suggests differences in the experience of child health among pesticide and non-pesticide using households.

[pt] Esta tese apresenta um novo espaço terapêutico grupal: o Espaço de acolhimento mãe-bebê. Sua dinâmica busca integrar a escuta psicanalítica a uma prática corporal - a massagem shantala para bebês -, objetivando consolidar o vínculo materno-infantil e facilitar os processos de integração somato-psíquico inerentes à constituição da subjetividade. Trata-se, sobretudo, de ressaltar a importância do trabalho psicanalítico no campo da provisão ambiental. Parte do pressuposto de que os processos de integração somato-psíquicos se constituem a partir de duas dimensões interatuantes: uma referente ao campo das experiências somáticas e outra em relação às trocas do indivíduo com o meio ambiente - o contexto sócio-cultural. O desenvolvimento da proposta apresentada - a criação do Espaço de acolhimento mãe-bebê - foi trabalhado a partir da elaboração de um referencial teórico-clínico-metodológico, com o objetivo de fundamentar e construir o campo. A pesquisa foi implementada no Posto de Saúde da comunidade Chapéu Mangueira, na cidade do Rio de Janeiro, onde mães e seus bebes foram introduzidas à técnica da shantala. A repercussão positiva do trabalho realizado conduziu a sua integração à rede de cuidados oferecidos pelo Posto. / [en] This thesis presents a new therapeutic grupal space: Mother- Baby s Holding Space. Its dynamics looks for an integration between psychoanalytic understanding to a corporal practice - the shantala massage for babies -, objectifying to consolidate the mother-infant relationship and to facilitate the somato-psychic integration processes inherent in the constitution of the subjectivity. It is, above all, of standing out the importance of the psychoanalytic work in the field of the environmental provision. The work is based on the assumption that the somato-psychic integration processes are constituted starting from two interacting dimensions: one regarding the somatic experiences areas, the other one relating to the individual s interchanges with the environment - the social-cultural context. The development of the presented proposal - the creation of a mother-baby s welcoming space - was based upon the elaboration of a theoretical-clinical- methodological referential network, aiming to establish the fundamental basis of the proposed field. The research was implemented in the Health Care Center of the community Chapéu Mangueira, in the city of Rio de Janeiro, where mothers and their babies were introduced to the technique of the shantala. The positive repercussion of the accomplished work drove its integration as one of the regular services offered by the Center.

[pt] O presente estudo tem por objetivo a compreensão do papel da mãe na relação com o bebê cardiopata. Baseado na teoria winnicottiana, mostra ser o meio-ambiente facilitador elemento fundamental para uma relação boa o bastante ou deficitária. Para a realização da pesquisa, utilizou-se entrevistas semi-estruturadas e aplicação de desenho sobre a relação mãe-bebê. Entrevistou-se 4 mães de bebês cardiopatas, com idades de 0 a 12 meses. Os resultados revelaram temas relacionados à forma como as mães se adaptam à situação de ter um filho com uma cardiopatia congênita, ao impacto causado na família, aos sentimentos e atitudes maternos e ao medo de perder o bebê. A partir disto, este estudo propõe que, tal como o bebê, a mãe precisa ser cuidada e apoiada. Para tal, é essencial cuidar também de seu meio-ambiente, representado pelo marido, pelos filhos, pela família e pelos amigos. O tipo de relação estabelecida entre a mãe e o bebê dependerá dos cuidados recebidos desse meioambiente. / [en] The objective of the present work is to understand the mother s role in its relation with the baby with congenital heart disease. Based on Winnicott s theory, it shows that the facilitating environment is the fundamental element for a good enough relationship or a not good enough one. An interview guide was used to collect the data, which has a semi-structured conversational format; mother-baby relationship s drawing were used too. Four mothers of babies (from 1 to twelve months old) with congenital heart disease had been interviewed. The results revealed themes related to the way these mothers get used to the situation of having a baby with congenital heart disease; to the impact caused in the family; to the maternal feelings and attitudes and to the fear of the baby s death. From these results, this study proposes that, just like the baby, the mother needs to be cared and supported. For this, it is essential to take care of the mother s environment too, represented by her husband, by her children, by her family and by her friends. The type of the relationship established between the mother and the baby will depend on the care taken by this environment.

A inserção do nióbio (Nb) como elemento de liga nos aços rápidos iniciou-se com o objetivo de substituir elementos de liga como o vanádio (V) e o tungstênio (W). A sinterização com fase líquida é uma das técnicas de fabricação de aços rápidos obtidos pela metalurgia do pó. O objetivo deste trabalho é a obtenção dos aços rápidos AISI M2 e M3:2 com e sem a adição de carboneto de nióbio (NbC) por compactação uniaxial a frio e sinterização a vácuo com fase líquida. Os pós dos aços rápidos AISI M2 e M3:2 foram processados por moagem de alta energia (MAE) com e sem adição de carboneto de nióbio e compactado uniaxialmente a frio a 700 MPa e sinterizados nas temperaturas de 1240 °C, 1270 °C, para os aços sem a adição de NbC e 1250 °C, para os aços com a adição de 6% de NbC. Os pós dos aços rápidos AISI M2 e M3:2 com a adição de carboneto de nióbio (NbC) processados por uma técnica de moagem de alta energia (MAE) foram caracterizados por difração de raios-X e Microscopia eletrônica de varredura (MEV) e espectroscopia de baixa energia dispersiva de raios-X (EDS) para avaliar a incorporação do reforço do carboneto de nióbio (NbC) aos pós elementares dos aços rápidos. Amostras dos aços rápidos AISI M2 e M3:2 sinterizadas a vácuo com e sem a adição de carboneto de nióbio (NbC) tiveram suas densidades avaliadas e as microestruturas foram caracterizadas por microscopia óptica (MO) para avaliar as microestruturas (porosidades, tamanho e distribuição de carbonetos). Os aços rápidos AISI M2 e M3:2 objetos desse trabalho de pesquisa foram avaliados ainda no que concerne a propriedade mecânica de dureza através de ensaios de dureza Vickers (HV).

In recent years, web has experienced a tremendous growth concerning users and content. As a result information overload problem has always been always one of the main discussion topics. The aim has always been to find the most desired solution in order to help users when they find it increasingly difficult to locate the accurate information at the right time. Recommender systems developed to address this need by helping users to find relevant information among huge amounts of data and they have now become a ubiquitous attribute to many websites. A recommender system guides users in their decisions by predicting their preferences while they are searching, shopping or generally surfing, based on their preferences collected from past as well as the preferences of other users. Until now, recommender systems has been vastly used in almost all professional e-commerce websites, selling or offering different variety of items from movies and music to clothes and foods. This thesis will present and explore different recommender system algorithms such as User-User Collaborative and Item-Item Collaborative filtering using open source library Apache mahout. Algorithms will be developed in order to evaluate the performance of these collaborative filtering algorithms. They will be compared and their performance will be measured in detail by using evaluation metrics such as RMSE and MAE and similarity algorithms such as Pearson and Loglikelihood.

[pt] Esta dissertação propõe-se a investigar e problematizar a relação mãefilha, na medida em que esta se apresenta conturbada e passional. Para se referir a esse tipo de relacionamento, Lacan o tratou como uma conseqüência do gozo feminino, a partir do termo devastação. O estudo aborda as dificuldades e especificidades dessa relação inicialmente a partir do exame das considerações freudianas sobre o Complexo de Édipo com relação à localização, a partir do Édipo de uma posição subjetiva na partilha dos sexos. A seguir, aborda as indicações de Jaques Lacan sobre o gozo feminino como um gozo que não é inteiramente recoberto pela normatização imposta pelo Édipo na criança. Este gozo seria aquele sobre o qual a mulher nada pode dizer, pois não existiria um símbolo específico do feminino que a permitisse articular saber e gozo, tal como o homem. Destaca-se a dificuldade na relação mãe e filha como a identificação problemática, já que é preciso, para a menina separar-se da mãe ao mesmo tempo em que precisa identificar-se com ela. / [en] This study intends to investigate and problematize the mother-daughter relationship, as long as it presents itself as troubled and passionate. To reflect about this type of relationship, Lacan treated it as a consequence of the feminine joy, using the term devastation. The essay approaches the difficulties and specificities of this relationship initially from the examination of Freud s considerations about the Oedipus complex as what concerns its location, from Oedipus complex to a subjective position in the sex partition. Afterwards, it approaches Lacan s indications about the feminine joy, as the joy that is not entirely covered by the standardize that comes from the Oedipus complex in a child. This joy would be the one which a woman cannot say anything about it, because there is no specific symbol of the feminine sex that would allow her to articulate knowledge and joy, such as it happens to the man. It is highlighted the difficulty in the mother-daughter relationship as a problematic identification, as soon as it is necessary to the girl to separate from her mother at the same time that she needs to identify herself with her mother.

In this paper we conduct an out-of-sample forecasting exercise for monthly Swedish air traveler volumes. The models considered are multiplicative seasonal ARIMA, Neural network autoregression, Exponential smoothing, the Prophet model and a Random Walk as a benchmark model. We divide the out-of-sample data into three different evaluation periods: Pre-COVID-19, during COVID-19 and Post-COVID-19 for which we calculate the MAE, MAPE and RMSE for each model in each of these evaluation periods. The results show that for the Pre-COVID-19 period all models produce accurate forecasts, in comparison to the Random Walk model. For the period during COVID-19, no model outperforms the Random Walk, with only Exponential smoothing performing as well as the Random Walk. For the period Post-COVID-19, the best performing models are Random Walk, SARIMA and Exponential smoothing, with all aforementioned models having similar performance.

[pt] As transformações socioculturais no Ocidente influenciaram profundamente a família contemporânea. As mudanças no papel da mulher e o seu deslocamento para o ambiente profissional fizeram com que os cuidados realizados com crianças pequenas fossem compartilhados por outros cuidadores, como por exemplo, as babás. O objetivo da pesquisa foi identificar as práticas e crenças de cuidado infantil realizado por mães e babás de famílias nucleares, e assim, comparar tais achados. O estudo de cunho qualitativo entrevistou 15 duplas de mães e babás, com filhos de até três anos de idade. As famílias residiam na zona sul do Rio de Janeiro. Foram realizadas entrevistas semiestruturadas, contendo nove questões, além das cinco imagens referentes aos sistemas parentais de Keller (2005). A maioria das mães apresentou escolaridade superior, enquanto as babás, ensino fundamental incompleto a ensino médio completo. Os resultados demostraram que mães e babás estabeleceram ordens semelhantes para as figuras dos sistemas parentais de cuidado. Outro dado identificou 12 categorias comuns referentes à prática de cuidados infantil desempenhada por mães e babás. A maioria das cuidadoras relatou a transmissão de crenças pessoais para as crianças a partir da interação e da prática de cuidados. O trabalho concluiu que as crenças e práticas dos cuidadores são fundamentais para o desenvolvimento infantil na primeira infância. / [en] Sociocultural transformations in the West have profoundly influenced the contemporary family. Changes in the role of women and their shift to the professional environment meant that care provided to young children was shared by other caregivers, such as nannies. The objective of the research was to identify childcare practices and beliefs carried by mothers and nannies form nuclear families, and thus compare these findings. The qualitative study interviewed 15 pairs of mothers and nannies, with children up to three years old. The families lived in the south of Rio de Janeiro. Semi-structured interviews were conducted, containing nine questions, in addition to the five images referring to Keller s parental systems (2005). Most mothers had higher education, while nannies, incomplete elementary school to complete high school. The results showed that mothers and nannies established similar orders for the figures of parental care systems. Another finding identified 12 common categories referring to the practice of child care performed by mothers and nannies. Most caregivers reported the transmission of personal beliefs to children from interaction and care practice. The paper concluded that caregivers beliefs and practices are fundamental to early child development.
