However, little has been studied about the spatial distribution of human capital in Brazil and its ability to act as a locational factor for economic activities. To fill this gap, this study proposes the creation of a multidimensional measure of qualitative human capital through Factor Analysis techniques, in addition to using a usual proxy for the quantitative aspect. Thus, it is possible to accompany the accumulation of human capital stock of the population from childhood to adulthood, either in qualitative or quantitative terms. This study is divided in two essays. In the first, the human capital measures were elaborated and a spatial analysis of the stock of quantitative and qualitative human capital was performed in Brazil, at the level of 558 micro-regions between 2009 and 2014. The results allow to draw the distribution map of human capital in the country, suggesting the existence of strong regional disparities: the South and Southeast regions present high quantity associated with high quality; North and Northeast, generally, present lower stocks in quantitative and qualitative aspects, although some micro-regions present high level of quantity that is not accompanied by increased quality; and Midwest presents intermediates and high levels of quantity, while the quality is only intermediate. Therefore, locations with a high quantity of human capital do not necessarily display a higher standard of quality (vice versa). Throughout the analyzed period, there occurred a slight improvement of the human capital?s levels in the country, especially in the quantitative aspect. In the second essay, through a spatial econometric model with panel data between 2009 and 2014 for 254 micro-regions of the South and Southeast regions of Brazil, a study supported on locational models for tertiary sector by level of intensity in knowledge was applied. This methodology allows us to identify the importance of different aspects of human capital in attracting economic activities: the quality of human capital is a locational factor for superior services (knowledge-intensive), while the quantitative aspect attracts both superior (intensive) and traditional services (non-knowledge-intensive). / Estudos recentes sugerem que disparidades regionais relativas ? qualidade do capital humano s?o importantes para explicar diferentes desempenhos de crescimento econ?mico. Entretanto, pouco tem sido estudado sobre a distribui??o espacial do capital humano no Brasil e sua capacidade de atuar como um fator locacional para as atividades econ?micas. Para preencher essa lacuna, nesta disserta??o, prop?e-se a cria??o de uma medida multidimensional de capital humano qualitativo atrav?s de t?cnicas de An?lise Fatorial, al?m de utilizar uma proxy usual para o aspecto quantitativo. Dessa forma, ? poss?vel acompanhar a acumula??o do estoque de capital humano da popula??o desde a inf?ncia at? a idade adulta, seja em termos qualitativos ou quantitativos. A disserta??o ? dividida em dois ensaios. No primeiro, constroem-se as medidas de capital humano e realiza-se uma an?lise espacial do estoque de capital humano em termos quantitativo e qualitativo no Brasil, em n?vel de 558 microrregi?es entre 2009 e 2014. Os resultados permitem desenhar o mapa de distribui??o do capital humano no territ?rio nacional, sugerindo a exist?ncia de fortes disparidades regionais: as regi?es Sul e Sudeste apresentam elevada quantidade associada ? alta qualidade; Norte e Nordeste, em geral, apresentam estoques inferiores em termos quantitativos e qualitativos, embora algumas microrregi?es possuam maior quantidade que n?o ? acompanhada pelo acr?scimo da qualidade; e Centro-Oeste apresenta n?veis intermedi?rios e altos de quantidade, enquanto a qualidade ? apenas intermedi?ria. Portanto, n?o necessariamente as localidades com alta quantidade de capital humano apresentam tamb?m elevada qualidade (vice-versa). Do ponto de vista de mudan?as ao longo do per?odo, em geral, verifica-se que ocorreu uma leve melhoria dos n?veis de capital humano no pa?s, principalmente no aspecto quantitativo. No segunso ensaio, atrav?s de um modelo econom?trico espacial com dados em painel, entre 2009 e 2014, para as 254 microrregi?es das Regi?es Sul e Sudeste do Brasil, aplica-se um estudo amparado em modelos locacionais para o setor de servi?os por n?vel de intensidade em conhecimento intr?nseco. Essa metodologia permite identificar a import?ncia de diferentes aspectos do capital humano para a atra??o das atividades econ?micas: verifica-se que a qualidade do capital humano ? um fator locacional para empresas de servi?os superiores (intensivos em conhecimento), enquanto o aspecto quantitativo atrai tanto os servi?os superiores (intensivos) como os tradicionais (n?o intensivos em conhecimento).

Dentre fatores sociais importantes para a avalia??o do idoso, merece destaque o Apoio Social, sobretudo o informal. Assim, os objetivos deste trabalho foram construir e validar um question?rio para avalia??o do apoio social informal para idosos. Trata-se de uma pesquisa descritiva, observacional, do tipo quantitativa. O projeto foi aprovado pelo comit? de ?tica em pesquisa do Hospital Universit?rio Onofre Lopes, sendo executado entre os meses de janeiro a dezembro de 2016 no munic?pio do Natal-RN e em outras localidades do Brasil por entrevistas presenciais com os idosos e question?rio autorrespondido virtualmente com os especialistas. Os crit?rios de inclus?o foram: experi?ncia comprovada na ?rea de apoio social (para especialistas) ou ter 60 anos ou mais e ter capacidade cognitiva preservada (para os idosos). Na etapa de Validade de Conte?do (VC), avaliou-se a relev?ncia dos itens segundo ?ndice de Validade de Conte?do (IVC) geral e por item e montagem de painel com as observa??es feitas pelos especialistas. Na etapa de Validade do Processo de Respostas (VPR), avaliou-se o entendimento referente aos itens pelo p?blico alvo. Para validade fatorial procedeu-se com An?lise Fatorial Explorat?ria (AFE). Para realiza??o da AFE foi usado o programa estat?stico M PLUS Vers?o 7?.

New demands for the integral care of the elderly are present and to be considered, the multidimensionality of health, its social aspects should also be considered in health assessment. Among important social factors for the assessment of the elderly, Social Support, especially the informal one, deserves special mention. Thus, the objectives of this study were to construct and validate a questionnaire to evaluate informal social support for the elderly. It is a descriptive, observational and quantitative research. The project was approved by the research ethics committee of the Onofre Lopes University Hospital, and was performed between January and December 2016 in the city of Natal-RN and other locations in Brazil through face-to-face interviews with the elderly and a questionnaire virtually answered by the specialists. Inclusion criteria were: proven experience in the social support area (for specialists) or 60 years of age or older and have preserved cognitive ability (for the elderly). In the Content Validity (CV) stage, was evaluated by relevance of the items according to the General Content Validity Index (CVI) and per item and panel assembly were evaluated with the observations made by the specialists. In the Validity of Process Responses (VPR) stage, the understanding of the items by the target audience was evaluated. For factorial validity we proceeded with Exploratory Factor Analysis (EFA). Using the statistical program M PLUS Version 7? was used. Variable grouping (type R) and factor extraction were performed with analysis of common factors, using oblique rotation Geomin. As exclusion criterion of the items was adopted a reference value greater than or equal to 0.35 of factorial load and greater or equal to 0.5 of commonality per item. To determine the amount of retained factors, the criteria of own values> 1, minimum cumulative explained variance of 60% and parallel Horn analysis were observed. In the CV stage with specialists, a total of 40 interviewees were obtained, 90% were PhD, 7.5% Masters and 2.5% Specialists. The general CVI was 0.88 and only one item had considered poor. After panel evaluation, two items were included and the others modified. In the VPR stage with the elderly, a total of 41 interviewees were obtained. After analyzing the panel of observations made by the elderly, the issues went through modifications for their improvement. A sample of 259 elderly people from the five regions of Brazil answered the questionnaire. After EFA, 4 items were excluded due to the poverty of their factorial loads and 4 factors were identified: "composition and extension of the social network", "support instrumental and availability", "reciprocity and longitudinality" and "support emotional support and social participation". The questionnaire showed a good relevance of the proposed items and the observations made by the interviewees allowed an approximation of the language used in the instrument, to the language used by the elderly. The instrument with 20 items and 4 retained factors presented good psychometric properties, such as: acceptable factor loads and excellent commonalities. We suggest 42 as the overall optimal cut score.

Pesquisa do Estado da Bahia - FAPEB / The present study aimed to analyze food consumption patterns and the nutritional status of children under four years old in Feira de Santana ? Bahia. It is a cross-sectional study nested in a cohortoflivebirths population based in Feira de Santana - Bahia.This study evaluated the data of 813 pairs of mothers and children under four years old from a cohort of live births. The anthropometric profile was defined through direct method by measuring the body mass index based on the variables height and weight and eating patterns (main independent variable) determined by principal component analysis through data obtained from the food frequency questionnaire.Also, were evaluated as potential confounders: child characteristics (sex, birth weight, nutritional status, interruption of exclusive breastfeeding at 4 months of age, weaning at twoyears old, bottle feeding, feeding during sleep and consumption of blended food) and maternal (gestational age, maternal age at birth, skin color, education, work, income, overweight / obesity), defined.The association between obesity and eating patterns were estimated using Pearson's chi-squared test (p <0.05) and multiple logistic regression analysis. In children under four years old, the prevalence of obesity was 12.7%.Regarding the children's characteristics, 51.7% were male, 95.7% were born weighting more than five pounds, eight ounces. Most children (96.4%) were born in the pregnancy term. 82.9% of mothers gave birth with age equal to or higher than 20 years old, 64.8% were brown, 66.4% had high school / college level education, 61.7% did not went away from home to work and 51.3% had income above 2 minimum wages.According to food characteristics, 21.2% continued exclusive breastfeeding until fourmonths and 10.9% still breastfeeding at 2 years old.The bottle use was reported in 63.0% of children, 29.5% ate sleeping and 47.6% were in the habit of consuming blended food. Four food consumption patterns were identified: food standard 1 (milk and derivatives, vegetables and tubers, legumes, fruit, fish and eggs); food pattern 2 (cereals, snacks, fats and oils, non-alcoholic drinks and sweets); food pattern 3 (processed meats, fast-food, ketchup/mayonnaise); and, food standard 4 (red meat and chicken).In the bivariate analysis, there was a positive association between obesity and the predictor variables: appropriate birth weight, family income, maternal overweight/obesity, interruption of exclusive breastfeeding at four months, no weaning attwoyears of age and use of bottle.In logistic regression analysis, obesity was associated with the consumption of processed meats, fast food and ketchup / mayonnaise (food standard 3). It has been shown that the high intake of processed and energy dense foods were contributing factors to the occurrence of obesity in childhood.These results reinforce the need for public policies and nutrition education programs in health facilities and schools, to assist in changing the eating habits of children, an important predictor of nutritional problems. / O presente estudo teve como objetivo analisar os padr?es de consumo alimentar e o estado nutricional de crian?as menores de quatro anos em Feira de Santana ?

Neste estudo foram avaliados os dados de 813 duplas m?es e filhos menores de quatro anos provenientes de uma coorte de nascidos vivos. O perfil antropom?trico foi definido pelo m?todo direto atrav?s da medida do ?ndice de massa corp?rea com base nas vari?veis peso e estatura e os padr?es alimentares (vari?vel independente principal), determinados por meio da an?lise de componentes principais atrav?s dos dados obtidos no question?rio de frequ?ncia alimentar. Al?m disso, foram avaliadas como potenciais confundidoras: as caracter?sticas infantis (sexo, peso ao nascer, estado nutricional, interrup??o do aleitamento materno exclusivo aos quatro meses de idade, desmame aos dois anos de idade, uso de mamadeira, alimenta??o durante o sono e consumode alimentos liquidificados) e as maternas (idade gestacional, idade materna no parto, cor da pele, escolaridade, trabalho, renda, sobrepeso/obesidade),definidas. A associa??o entre a obesidade e os padr?es alimentaresfoiestimada atrav?s do teste qui-quadrado de Pearson (p<0,05) e da an?lise de regress?o log?stica m?ltipla.Nas crian?as menores de quatro anos, apreval?ncia de obesidadefoi de12,7%. Com rela??o ?s caracter?sticas infantis, 51,7% eram do sexo masculino, 95,7% nasceram com peso superior a 2500g. A maioria das crian?as (96,4%) nasceuno termo da gesta??o.82,9% das m?es pariram com idade igual ou superior a 20 anos, 64,8% eram pardas, 66,4% tinham ensino m?dio/superior, 61,7% n?o se ausentavam do lar para trabalhar e 51,3% tinham renda superior a 2 sal?rios m?nimos. Segundo as caracter?sticas alimentares, 21,2% continuaram o aleitamento exclusivo at? os 4 meses e 10,9% ainda amamentavam aos 2 anos de idade. O uso de mamadeira foi reportado em 63,0% das crian?as, 29,5% comiam dormindo e 47,6% tinham o h?bito de consumir alimentos liquidificados.Foram identificados quatro padr?es alimentares: padr?o alimentar 1 (leite e derivados, verduras e tub?rculos, leguminosas, frutas, pescados e ovos); padr?o alimentar 2 (cereais, salgadinhos, ?leos e gorduras, bebidas n?o alco?licas e doces); padr?o alimentar 3 (embutidos, fast-food, catchup/maionese); e padr?o alimentar 4 (frango e carnes vermelhas).Na an?lise bivariada,observou-se associa??o positiva entre a obesidade e as vari?veis preditoras: peso adequado ao nascer, maior renda familiar, sobrepeso/obesidade materno, interrup??o do aleitamento materno exclusivo aos 4 meses, aus?ncia de desmame aos 2 anos de idade e uso de mamadeira. Na an?lise de regress?o log?stica, aobesidade esteve associada com o consumode alimentos embutidos, fast-food e catchup/maionese (padr?o alimentar 3).Ficou demonstrado que a elevada ingest?o de alimentos industrializados e altamente energ?ticos foram fatores contributivos para a ocorr?ncia da obesidade na inf?ncia. Estes resultados refor?am a necessidade de pol?ticas p?blicas e programas de educa??o alimentar, nas unidades de sa?de e escolas, que auxiliem na mudan?a dos h?bitos alimentares das crian?as, importante preditor de problemas nutricionais.

However, despite the advances in the use of geoprocessing tools, an accurate alert and monitoring system of landslides has not yet been developed. From a technical point of view, this is due to the little quantitative understanding of the variables influencing the mass movements in the city, as well as the limited availability of detailed soil attribute maps that have direct effect on landslides (e. g. depth, water retention and water flow). This paper presents the hypothesis that there is still a lack of a quantitative study of the relationship between landslides events and its determinants. The objectives of this study were: a) to evaluate the changes of land use in the municipality between the years 1984 to 2014, through satellite images classification; b) to apply factor analysis binary correspondence (FABC) on the physical constraints that has the potential to explain the occurrence of landslide; c) To use the FABC results to generate landslide susceptibility map. To develop the study, we used the following dataset and maps, landslides data and satellite images: cadastral topographic map (1: 10,000), soil map (1: 25,000), land use map from 2002 (1: 25,000), 384 georeferenced events of landslide (CPRM), and orbital images of Landsat -5 and -8 (INPE and USGS, respectively) in the period between 1984 to 2014. The landslide susceptibility map was validated using 25% of the landslides events of the original dataset, which were randomly selected. The land use maps show that despite the dramatic disasters associated with landslide, the urban area has almost doubled (from 23 km? in 1984 to 47 km? in 2014), with significant increase in the period between 2010-2014. The FABC stressed the most important variables associated with the landslides, which were: anthropic use (U3C), urban use (U4Z), hillside with rectilinear curvature (C2), steepness ranging from strong undulating to mountainous class (I2) and topographic wetness index ranging from 5 to 10 (TWI2). The BCFA further allowed defining the weights and the grades of each variable to generate the landslide susceptibility map, reducing the subjectivity in map generation. The High and Very High classes of landslide susceptibility map represent 61.78% of the territory and the accuracy reached 91.69% (54.17% of events in the very high and 37.52% in the high class). However, it is believed that the areas classified as high and very high can be better discriminated by introducing the soil depth and water retention maps. This gain of knowledge could improve the accuracy of the alert systems for landslides. / Os movimentos de massa (M.M) no munic?pio de Angra dos Reis t?m sido tradados como um grave problema para o poder p?blico e autoridades, pois o n?mero de v?timas fatais e os danos e preju?zos socioecon?micos e ambientais s?o crescentes. No entanto, apesar do avan?o no uso de ferramentas de geoprocessamento, ainda n?o se desenvolveu um sistema de alerta e monitoramento de M.M. Do ponto de vista t?cnico, isso se deve ao pouco conhecimento quantitativo das vari?veis que influenciam os movimentos de massa no munic?pio, bem como a pouca disponibilidade de mapas detalhados de atributos do solo que t?m efeito direto nos M.M (exemplo: profundidade, reten??o de ?gua e fluxo de ?gua dos solos). Neste trabalho apresenta-se a hip?tese de que falta ainda um estudo mais aprofundado e quantitativo da rela??o entre os eventos de M.M. e seus fatores determinantes. Assim, os objetivos desse estudo foram: a) avaliar as mudan?as do uso do solo no munic?pio entre os anos de 1984 e 2014, por meio da classifica??o de imagens orbitais; b) aplicar a an?lise fatorial de correspond?ncia bin?ria (AFCB) nas condicionantes f?sicas que tem potencial para explicar a ocorr?ncia de M.M.; c) utilizar os resultados da AFCB para gerar mapas de suscetibilidade a M.M. Para o desenvolvimento do estudo utilizou-se os seguintes bancos de dados e mapas, dados de M.M e imagens dispon?veis: mapa topogr?fico cadastral (1:10.000), mapa de solo (1:25.000), mapa de uso do solo (1:25.000 ? 2002), 384 eventos de M.M georreferenciados (CPRM), imagens orbitais dos sat?lites Landsat -5 e Landsat -8 (INPE e USGS, respectivamente) dos anos de 1984 a 2014. O mapa de suscetibilidade a M.M. foi validado a partir da compara??o da classifica??o efetuada com 25% dos eventos selecionados aleatoriamente. Os mapas de classes de uso demonstram que apesar das dram?ticas cat?strofes associadas aos M.M., a ?rea urbana praticamente dobrou (de 23 km? em 1984 para 47 km? em 2014), com sens?vel aumento no per?odo de 2010 a 2014. A AFCB destacou que as vari?veis mais importantes associadas aos M.M. foram: uso campo antr?pico (U3C), uso urbano (U4Z), curvatura do terreno retil?nea (C2), classe de declividade forte ondulada a montanhosa (I2) e ?ndice topogr?fico de umidade variando de 5 a 10 (TWI2). A AFCB permitiu ainda auxiliar na decis?o dos pesos e notas de cada vari?vel para gerar o mapa de suscetibilidade a M.M, reduzindo a subjetividade na gera??o do mapa. As classes de suscetibilidade Alta e Muito Alta ao M.M. representam 61.78% do territ?rio e a acur?cia atingiu 91.69% (54.17% dos eventos na classe muito alta e 37.52% na alta). No entanto, acredita-se que as ?reas classificadas como alta e muito alta possam ser melhor discriminadas com a introdu??o de mapas de profundidade do solo e de reten??o de ?gua. Esse ganho de conhecimento aperfei?oaria o desenvolvimento de sistemas de alerta a M. M.

No. of bitstreams: 1 ALINE DA SILVA BOSCHI MARTINS NEVES.pdf: 1713644 bytes, checksum: f8d45029bc62915e3c5e77690c011494 (MD5) Previous issue date: 2018-02-26 / Stress is one of the constructs emphasized when evaluating the health-disease process. However, because it is a latent variable, specific instruments are needed to measure it. The Perceived Stress Scale (PSS) is an instrument that has been used to assess the perception of stress in the last month. Despite numerous validations in several countries, their psychometric properties have not been consensual. The main objective of this work was to investigate the internal structure of the PSS-10 and PSS-14 versions, through exploratory factorial (AFE) and network analysis. Thus, two studies were carried out: in Study I, PSS-10 and PSS-14 were analyzed through AFE and, in study II, the scales were analyzed through network analysis. We used: a) the PSS-10 with a sample composed of 686 participants, being 175 (27.3%) men and 466 (72.7%) women (n = 641), with a mean age of 33.9 SD = 11.3) years, ranging from 18 to 73 (n = 632); and (b) the PSS-14 was answered by 690 participants, of which 304 (44.1%) were men and 386 (55.9.7%) were women, with a mean age of 34.72 (SD = 12, 56), with a range of 18 to 65. In both analyzes, the psychometric properties of PSS-10 and PSS-14 were shown to be reliable and confirmed the two-dimensional structure of distress and coping. Also, the network analysis allowed to explore the PSS in the Brazilian context, allowing new association patterns to emerge from the analyzed samples. And, even AFE being a widely used technique in the construction and evaluation of psychometric tests, network analysis has shown to be a promising and much more comprehensive tool at the level of the symptom, accommodating the numerous processes of psychological constructions. In this study, the network analysis showed how the perception of control influences the outcome of stress. Thus, in addition to providing evidence of validity of the PSS-10 and PSS-14, this study demonstrated how much the network analysis has to contribute in the psychology and health area. / O estresse ? um dos construtos enfatizados quando se avalia o processo sa?de- doen?a. No entanto, por ser uma vari?vel latente, instrumentos espec?ficos s?o necess?rios para mensur?-lo. A Escala de Estresse Percebido (Perceived Stress Scale - PSS) ? um instrumento que tem sido utilizado para avaliar a percep??o do estresse no ?ltimo m?s. Apesar de in?meras valida??es em diversos pa?ses, suas propriedades psicom?tricas n?o t?m sido consensuais. O objetivo principal deste trabalho foi investigar a estrutura interna das vers?es PSS-10 e PSS-14, por meio de an?lise fatorial explorat?ria (AFE) e de rede. Assim, dois estudos foram realizados: no Estudo I, a PSS-10 e a PSS-14 foram analisadas atrav?s da AFE e, no estudo II, analisaram-se as escalas por meio da an?lise de rede. Foram utilizadas: a) a PSS-10 com uma amostra composta por 686 participantes, sendo 175 (27,3%) homens e 466 (72,7%) mulheres (n = 641), com m?dia de idade de 33,9 (SD = 11,3) anos, com amplitude de 18 a 73 (n = 632); e b) a PSS-14 que foi respondida por 690 participantes, dos quais 304 (44,1%) s?o homens e 386 (55,9,7%), mulheres, com m?dia de idade de 34,72 (SD = 12,56) anos, com amplitude de 18 a 65. Nas duas an?lises, as propriedades psicom?tricas da PSS-10 e PSS-14 demonstraram-se confi?veis e confirmaram a estrutura bidimensional de distress e coping. Ainda, a an?lise de rede permitiu explorar a PSS no contexto brasileiro, permitindo que novos padr?es de associa??o emergissem das amostras analisadas. E, mesmo a AFE sendo t?cnica muito utilizada na constru??o e avalia??o de testes psicom?tricos, a an?lise de rede demonstra ser uma ferramenta promissora e muito mais abrangente no n?vel do sintoma, acomodando os numerosos processos das constru??es psicol?gicas. Neste estudo, a an?lise de rede evidenciou o quanto a percep??o de controle influencia no desfecho do estresse. Assim, al?m de fornecer evid?ncias de validade da PSS-10 e PSS-14, este estudo demonstrou o quanto ? an?lise de rede tem a contribuir no ?mbito da psicologia e na ?rea da sa?de.
