With the increased energy demands which are needed to fuel the human development and economic growth we also observe a trend for global environmental problems caused by burning fossil fuels. Tackling problems like global warming would mean either tapping into the large CO2 emitters and having them shift to renewable energy alternatives or motivating change on the level of individuals which would lead to a general reduction in energy consumption. This thesis features an online experiment with 320 participants, recruited through Amazon Mechanical Turk, who were randomly assigned to either an environmental or an economic frame, and performed tasks on energy-related investments, risk elicitation and environmental preferences (by framing we mean controlling the formulation of the decision problem). The main purpose of the experiment was to examine the effects of framing on the decision-making processes of households in regards to energy investments. The results we obtained with 90 and 99% confidence provide evidence that framing does have an effect on investment choices, moreover we have also observed that environmental concern is an important predictor of households’ investments. Going beyond our main hypothesis, we have conducted some exploratory analysis of the data which highlighted a great potential for the scientific method within the domain of energy-related investments. Finally, the results from our experiment suggest that framing could be a successful instrument in the hands of those working with policy-making and communication.

Esta dissertação objetivou investigar a relação entre o nível de realização de tarefas domésticas e as áreas de interesse dos projetos de vida na adolescência. Diante do exposto pela literatura investigada, três hipóteses nortearam o estudo: (H1) o nível de realização de tarefas domésticas apresentará relação com os diferentes tipos de projetos de vida citados pelos adolescentes; (H2) o nível de realização de tarefas domésticas apresentará relação negativa com o desempenho escolar; e (H3) serão observadas diferenças de gênero quando essas mesmas relações forem analisadas separadamente para adolescentes do sexo masculino e feminino. Participaram 113 adolescentes brasileiros (61,9% do sexo feminino), todos alunos de escolas municipais de Porto Alegre – RS. Utilizaram-se uma ficha de dados biossociodemográficos, o Questionário de Tarefas Domésticas e de Cuidado entre Irmãos (QTDCI) e um depoimento escrito sobre projetos de vida. As análises das correlações de Pearson indicaram, para a amostra geral, uma associação positiva entre nível de tarefas domésticas e projetos de vida relacionados a bens materiais, e nenhuma associação entre tarefas domésticas e as variáveis de desempenho escolar. Contudo, quando estratificada a amostra por gênero, as associações encontradas foram diferentes para adolescentes dos sexos masculino e feminino. Os resultados sugerem que a realização de tarefas domésticas pode ser fator de influência na elaboração dos projetos de vida de adolescentes, e que importantes questões de gênero se fazem presentes nesta relação. / The aim of this dissertation was to investigate the relation between household responsabilities level and the areas of interest on adolescents’ life purposes. Considering the literature foundings, three hypotheses guided the study: (H1) the household responsabilities level will be related to the different areas of interest of life purposes cited by the adolescents; (H2) the level of household responsabilities will be negatively related to school performance; and (H3) gender differences will be observed when these same relations are analyzed separately for male and female adolescents. Participants were 113 Brazilian adolescents (61,9% female), all students from municipal schools in Porto Alegre - RS. The instruments were a record of biosocio-demographic data, the Household and Sibling Care Questionnaire, and a written testimony of life purpose. Pearson's correlations for the general sample indicated a positive association between household responsabilities level and purposes related to material goods, and no association between household responsabilities level and school performance variables. However, when the sample was stratified by gender, different associations were found for each group. The results suggest that the accomplishment of household tasks can influence the development of life purpose in adolescents, and that important gender issues are present in this relation.

Research into energy demand in office buildings has tended to focus on building fabric or systems, or the organisation as a whole, rather than the actions or motivations of individual building occupants. This study applies an attitude-behaviour approach used more frequently with household or travel behaviours to energy demand behaviours by individual occupants in office settings. The approach is extended to include contextual factors such as behavioural control, organisational expectations and social influences. Comparisons are drawn between the office and home settings. The study took place in the offices of two local authorities, Nottingham City Council and Nottinghamshire County Council, and included a questionnaire survey (n=819), semi-structured interviews (n=9), and building surveys (n=5). Behaviours examined included switching off lights, computers and computer monitors. Lighting behaviours were reported to be carried out more frequently than computer monitor behaviours in both the office and household settings. Analysis of behaviours identified that they needed to be considered at a specific level, according to the equipment (lighting, computer monitors), setting (office, home), and triggers (finishing a task, leaving a room). The physical context of the behaviour was particularly important. Different levels of individual control over energy affected the performance of behaviours. No evidence was found to support the notion of spillover that enacting one energy demand behaviour might lead to the enactment of further energy demand behaviours, including for similar behaviours performed in different settings (e.g. the office and the home). Organisational, social and psychological/attitudinal influences on individual behaviour were also examined. Structural Equation Modelling examined influences proposed by the Theory of Planned Behaviour and Values-Beliefs-Norms Theory. Neither theory provided a strong explanation of the collected data. However, support was found for the Perceived Behavioural Control construct, while moral and value-led constructs had a small influence on behaviour. This thesis provides recommendations for practitioners and policy makers seeking to reduce individual-level energy demand in office settings, and for future research into energy use in organisational settings. Recommendations include promoting energy saving as an aspect of professionalism, characterising energy demand behaviours specifically by setting and equipment, and recognising the importance of the social aspects of shared office environments.

Based on this assumption, this research consists of a descriptive epidemiological and longitudinal study of recorded cases of leprosy, whose goal is to analyze the prevalence of leprosy parallel to the transmission chain in the city of Imperatriz-MA, from 2002 to 2012. s Research was performed with patients with leprosy living in the City of Imperatriz-MA, duly registered in SINAN (Information System for Notifiable Diseases). Among the findings, are: 35% of reported cases presented in the form of multibacillary borderline classification; age of most patients were ≥ 15 years; examined in relation to contacts not been possible to achieve the goal proposed by the Ministry of Health, and in some years, the low coverage did not influence the increased incidence of leprosy; decreased the number of deaths and the dropout rate significantly; and failure in completing the records of the type of reactions presented mainly in the period 2002-2005. Analyzing the epidemiological situation of leprosy in the village of Imperatriz-MA, it is concluded that the remains endemic despite the significant decrease in the number cases during this period, and that eradication of the disease in the state of Maranhão, is a distant reality, with a prevalence of cases 10:54 10.0 per thousand in 2012 in the municipality of the study. / O controle efetivo da hanseníase tem desafiado a organização dos serviços de saúde, em razão do longo período de incubação e pela alta prevalência de casos, além das sequelas e incapacidades decorrentes da doença. Partindo desse pressuposto, esta pesquisa consiste em um estudo epidemiológico descritivo e longitudinal dos casos registrados de hanseníase, cujo objetivo é analisar a prevalência da hanseníase paralela à cadeia de transmissão no Município de Imperatriz-MA, no período de 2002 a 2012. A pesquisa foi realizada com portadores de Hanseníase residentes no Município de Imperatriz-MA, devidamente registrado no SINAN (Sistema de Informação de Agravos de Notificação). Dentre os resultados encontrados, destacam-se: 35% dos casos notificados apresentaram-se na forma dimorfa de classificação multibacilar; idade da maioria dos portadores era ≥ 15 anos; em relação aos contatos examinados não foi possível atingir a meta proposta pelo ministério da Saúde, e, em alguns anos, a baixa cobertura não influenciou no aumento da incidência da hanseníase; houve redução do número de óbitos e da taxa de abandono de forma significativa; e falha no preenchimento dos registros quanto ao tipo de reações apresentadas, principalmente no período de 2002 a 2005. Ao analisar a situação epidemiológica da hanseníase no município de Imperatriz-Ma, concluise que a endemia se mantém, apesar da diminuição significativa do número de casos neste período, e que a erradicação dessa doença no estado do Maranhão, é uma realidade ainda distante, com prevalência de 10.54 casos por 10.0 mil habitantes em 2012 no município do estudo.

This thesis is concerned with a fundamental unit of the economy: Households. Even in advanced economies, upwards of 70% of the population live in households composed of multiple people. A large number of decisions are taken at the level of the household, that is to say, they are taken jointly by household members: How to raise children, how much and when to work, how many cartons of milk to purchase. How these decisions are made is therefore of great importance for the people who live in them and for their well-being.But precisely because household members make decisions jointly it is hard to know how they come about and to what extent they benefit individual members. This is why households are often viewed as unique decision makers in economics. Even if they contain multiple people, they are treated as though they were a single person with a single set of preferences. This unitary approach is often sufficient and can be a helpful simplification. But in many situations it does not deliver an adequate description of household behavior. For instance, the unitary model does not permit the study of individual wellbeing and inequality inside the household. In addition, implications of the unitary model have been rejected repeatedly in the demand literature.Bargaining models offer an alternative where household members have individual preferences and come to joint decisions in various ways. There are by now a great number of such models, all of which allow for the study of bargaining power, a measure of the influence a member has in decision making. This concept is important because it has implications for the welfare of individuals. If one household member’s bargaining power increases, the household’s choices will be more closely aligned with that member’s preferences, ceteris paribus.The three chapters below can be divided into two parts. The first part consists of Chapter 1, which looks to detect the influence of intra-household bargaining in a specific set of consumption choices: Consumption of the arts. The research in this chapter is designed to measure aspects of the effect of bargaining power in this domain, but does not seek to quantify bargaining power itself or to infer economic well-being of household members.Precisely this last point, however, is the focus of the second part of the thesis, consisting of Chapters 2 and 3. These focus specifically on the recovery of one measure of bargaining power, the resource share. Resource shares have the advantage of being interpretable in terms of economic well-being, which is not true of all such measures. They are estimated as part of structural models of household demand. These models are versions of the collective model of household decision making.Pioneered by Chiappori (1988) and Apps and Rees (1988), the collective model has become the go-to alternative to unitary approaches, where the household is seen as a single decision-making unit with a single well-behaved utility function. Instead, the collective model allows for individual utility functions for each member of the household. The model owes much of its success to the simplicity of its most fundamental assumption: That whatever the structure of the intra-household bargaining process, outcomes are Pareto-efficient. This means that no member can be made better off, without making another worse off. Though the model nests unitary models as special cases, it does have testable implications.The first chapter of the thesis is entitled “Household Decisions on Arts Consumption” and is joint work with Caterina Mauri, who has also collaborated with me on many other projects in her capacity as my girlfriend. In it, we explore the role of intra-household bargaining in arts consumption. We do this by estimating demand for various arts and cultural events such as the opera or dance performances using a large number of explanatory variables. One of these variables plays a special role. This variable is a distribution factor, meaning that it can be reasonably assumed to affect consumption only through the bargaining process, and not by modifying preferences. Such variables play an important role in the household bargaining literature. Here, three such variables are used. Among them is the share of household income that is contributed by the husband, the canonical distribution factor.The chapter fits into a literature on drivers of arts consumption, which has shown that in addition to such factors as age, income and education, spousal preferences and characteristics are important in determining how much and which cultural goods are consumed. Gender differences in preferences in arts consumption have also been shown to be important and to persist after accounting for class, education and other socio-economic factors (Bihagen and Katz-Gerro, 2000).We explore to what extent this difference in preferences can be used to shed light on the decision process in couples’ households. Using three different distribution factors, we infer whether changes in the relative bargaining power of spouses induce changes in arts consumption.Using a large sample from the US Current Population Survey which includes data on the frequency of visits to various categories of cultural activities, we regress atten- dance rates on a range of socio-economic variables using a suitable count data model.We find that attendance by men at events such as the opera, ballet and other dance performances, which are more frequently attended by women than by men, show a significant influence of the distribution factors. This significant effect persists irrespec- tively of which distribution factor is used. We conclude that more influential men tend to participate in these activities less frequently than less influential men, conditionally on a host of controls notably including hours worked.The second chapter centers around the recovery of resource shares. This chapter is joint work with Denni Tommasi, a fellow PhD student at ECARES. It relies on the collective model of the household, which assumes simply that household decisions are Pareto-efficient. From this assumption, a relatively simple household problem can be formulated. Households can be seen as maximizers of weighted sums of their members’ utility functions. Importantly the weights, known as bargaining weights (or bargaining power), may depend on many factors, including prices. The household problem in turn implies structure for household demand, which is observed in survey data.Collective demand systems do not necessarily identify measures of bargaining power however. In fact, the ability to recover such a measure, and especially one that is useful for welfare analysis, was an important milestone in the literature. It was reached by (Browning et al. 2013) (henceforth BCL), with a collective model capable of identi- fying resource shares (also known as a sharing rule). These shares provide a measure of how resources are allocated in the household and so can be used to study intra- household consumption inequality. They also take into account that households gen- erate economies of scale for their members, a phenomenon known as a consumption technology: By sharing goods such as housing, members of households can generate savings that can be used elsewhere.Estimation of these resource shares involves expressing household budget shares functions of preferences, a consumption technology and a sharing rule, each of which is a function of observables, and letting the resulting system loose on the data. But obtaining such a demand system is not free. In addition to the usual empirical speci- fications of the various parts of the system, an identifying assumption has to be made to assure that resource shares can be recovered in estimation. In BCL, this is the assumption that singles and adult members of households share the same preferences. In Chapter 2, however, an alternative assumption is used.In a recent paper, Dunbar et al. (2013) (hereafter DLP) develop a collective model based on BCL that allows to identify resource shares using assumptions on the simi- larity of preferences within and between households. The model uses demand only for assignable goods, a favorite of household economists. These are goods such as mens’ clothing and womens’ clothing for which it is known who in a household consumes them. In this chapter, we show why, especially when the data exhibit relatively flat Engel curves, the model is weakly identified and induces high variability and an im- plausible pattern in least squares estimates.We propose an estimation strategy nested in their framework that greatly reduces this practical impediment to recovery of individual resource shares. To achieve this, we follow an empirical Bayes method that incorporates additional (or out-of-sample) information on singles and relies on mild assumptions on preferences. We show the practical usefulness of this strategy through a series of Monte Carlo simulations and by applying it to Mexican data.The results show that our approach is robust, gives a plausible picture of the house- hold decision process, and is particularly beneficial for the practitioner who wishes to apply the DLP framework. Our welfare analysis of the PROGRESA program in Mexico is the first to include separate poverty rates for men and women in a CCT program.The third Chapter addresses a problem similar to the one discussed in Chapter 2. The goal, again, is to estimate resource shares and to remedy issues of imprecision and instability in the demand systems that can deliver them. Here, the collective model used is based on Lewbel and Pendakur (2008), and uses data on the entire basket of goods that households consume. The identifying assumption is similar to that used by BCL, although I allow for some differences in preferences between singles and married individuals.I set out to improve the precision and stability of the resulting estimates, and so to make the model more useful for welfare analysis. In order to do so, this chapter approaches, for the first time, the estimation of a collective household demand system from a Bayesian perspective. Using prior information on equivalence scales, as well as restrictions implied by theory, tight credible intervals are found for resource shares, a measure of the distribution of economic well-being in a household. A modern MCMC sampling method provides a complete picture of the high-dimensional parameter vec- tor’s posterior distribution and allows for reliable inference.The share of household earnings generated by a household member is estimated to have a positive effect on her share of household resources in a sample of couples from the US Consumer Expenditure survey. An increase in the earnings share of one percentage point is estimated to result in a shift of between 0.05% and 0.14% of household resources in the same direction, meaning that spouses partially insure one another against such shifts. The estimates imply an expected shift of 0.71% of household resources from the average man to the average woman in the same sample between 2008 and 2012, when men lost jobs at a greater rate than women.Both Chapters 2 and 3 explore unconventional ways to achieve gains in estimator precision and reliability at relatively little cost. This represents a valuable contribution to a literature that, for all its merits in complexity and ingenious modeling, has not yet seriously endeavored to make itself empirically useful. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

Essa tese de doutorado tem como objetivo estudar o diferencial de gênero no tempo de commuting dos indivíduos e entender sua relação com a Hipótese da Responsabilidade Doméstica (HRH, em inglês). Em um primeiro momento busca-se identificar as diferenças no comportamento de viagens a trabalho de homens e mulheres e associá-las à HRH, ao passo que a segunda parte vai mais a fundo na questão da divisão de tarefas e analisa o papel das normas sociais como motor do diferencial de gênero no tempo de commuting. Lançando mão de informações provenientes da Pesquisa Nacional por Amostra de Domicílios (PNAD) de 2011 a 2015 para indivíduos casados, a primeira parte constrói uma métrica para o grau de responsabilização do cônjuge com os afazeres domésticos e investiga a sua importância na determinação do tempo de commuting. Os principais resultados indicam que gênero só se apresenta como característica relevante para explicar a duração do deslocamento ao trabalho nos cenários em que a parcela desempenhada de afazeres domésticos não é levada em consideração. Testes de robustez mostram que o efeito da HRH sobrevive mesmo quando incluídos nas regressões aspectos do mercado de trabalho que tradicionalmente são apontados como explicações para homens e mulheres apresentarem diferentes durações do commuting. Reconhecendo que a divisão de afazeres domésticos é influenciada pelos papéis de gênero que cada cônjuge assume dentro de um casamento, a segunda parte utiliza dados do Censo Brasileiro de 2010 para incluir na análise casais do mesmo sexo e entender como as normas sociais podem ser responsáveis pelas diferentes durações no trajeto casa-trabalho de homens e mulheres. Os resultados revelam que casais do mesmo sexo apresentam maior probabilidade de terem o mesmo tempo de commuting e que mulheres que se relacionam com outras mulheres conseguem ter maior mobilidade no espaço urbano, trazendo evidências de que o afrouxamento das normas sociais, materializado na não-designação tradicional de papéis sociais de gênero em um casamento, tem efeitos positivos sobre a igualdade do commuting. A pesquisa aqui desenvolvida expande a fronteira do conhecimento em várias frentes, a começar por trazer a discussão para fora do eixo dos países desenvolvidos. Mais importante ainda, discute o desenrolar da HRH no que diz respeito à capacidade de se locomover no espaço em busca de melhores oportunidades de emprego. Finalmente, a pesquisa ainda traz insights sobre a diferença entre gênero e papéis de gênero como condicionantes do comportamento de viagem dos indivíduos, permitindo que políticas públicas sejam desenhadas visando mitigar os efeitos adversos da HRH para as mulheres. / This dissertation deals with the gender differential in the commuting time of individuals and aims to understand its relationship with the Household Responsibility Hypothesis (HRH). First, it seeks to identify the differences in the behavior of travel to work for men and women and to associate them with HRH. The second part explores the issue of the division of household chores and analyzes the role of social norms as the motor of the gender differential in commuting time. Using information from the National Household Sample Survey (PNAD) from 2011 to 2015 for married individuals, the first part constructs a metric for the degree of accountability of the spouse to household chores and investigates their importance in determining commuting time. The main results indicate that gender is a relevant characteristic only to explain travel time to work in the scenarios in which the portion of household chores performed is not taken into account. Moreover, robustness tests show that the HRH effect persists even when aspects of the labor market that are traditionally pointed out as explanations for men and women presenting different durations of commuting are included in the regressions. Acknowledging that household chores are influenced by the gender roles each spouse takes in a marriage, the second part uses data from the 2010 Brazilian Census to include same-sex couples in the analysis to understand how social norms can account for different commuting times for men and women. The results show that same-sex couples are more likely to have the same commuting time and that women who relate to other women are able to have greater mobility in the urban space, bringing evidence that the loosening of social norms, materialized by the non-designation of traditional gender roles in a marriage, has positive effects on commuting equality. The research developed here pushes the boundary of knowledge on several fronts, starting with exploring the issue out of the usual circuit of developed countries. More importantly, it discusses the development of HRH with regard to the ability to move around in space in search of better employment opportunities. Finally, the research brings insights into the difference between gender and gender roles as constraints on individuals\' travel behavior, enabling the design of public policies to mitigate the adverse effects of HRH for women.

O contexto do envelhecimento dos idosos mais velhos necessita ser considerado em decorrência dos fatores socioeconômicos, políticos e demográficos do país, além do processo de redefinição da família como instituição social. Dessa forma, a pesquisa relacionada aos arranjos domiciliares e a rede de suporte social, vem de encontro com as questões relacionadas ao cuidado do idoso no domicilio, principalmente dos idosos mais velhos. Tratase de um estudo epidemiológico, transversal, que teve por objetivo caracterizar o arranjo domiciliar e a rede de suporte social dos idosos mais velhos residentes na comunidade de Ribeirão Preto, SP, além da sua funcionalidade. A amostra constituiu-se de 147 idosos. Os dados foram coletados em entrevistas domiciliares, utilizando-se identificação e perfil social, o Mapa Mínimo de Relações do Idoso (MMRI) para investigar a rede de suporte, a Medida de Independência Funcional (MIF) e questões sobre os arranjos domiciliares. A idade média das idosas foi de 84,4 anos e dos idosos de 84,1 anos, sendo 63,3% na faixa etária de 80-84 anos, 27,2% na de 85-89 anos e 9,5% na de 90 anos ou mais. Há maior número de idosas viúvas, 91,3% e analfabetas, 83,3%. Do total dos idosos, 41,5% recebem aposentadoria, possuem de um a três salários mínimos (72,1%) e moram em casa própria quitada (74,1%). Os idosos possuem em média 4,08 filhos e residem com 2,8 pessoas. Quanto à funcionalidade, a variação dos escores observados foi igual à variação possível da MIF motora, cognitiva social e total, assim como em seus domínios, com a média das pontuações próxima aos valores máximos possíveis. A maioria dos idosos classificou-se na categoria independência completa/modificada, 81,6% e 15% na dependência mínima. À medida que os idosos se tornam mais velhos se tornam mais dependentes (p < 0, 001). Não foi encontrada significância estatística entre a MIF total e arranjo domiciliar, apesar da tendência de morar sozinho aumentar conforme aumenta a pontuação na MIF. A relação com o suporte social também não foi significativa. Grande parte dos idosos vive com o cônjuge, 26,5% e 14,3% vivem sozinhos. Mais da metade dos domicílios são chefiados pelo próprio idoso, 57,1%. Conforme aumenta a faixa etária diminui o número de idosos que vivem com o cônjuge e aumenta os que vivem com os filhos. Quanto à configuração da rede de suporte social dos idosos, houve predomínio de pessoas no primeiro círculo, isto é, freqüentemente, com ênfase para os filhos e familiares, para todas as funções analisadas. A média do número de amigos e pessoas da comunidade para todos os tipos de apoio foi menor que um, o que reforça a família como protetora e cuidadora dos idosos. / The context of aging of the elder elderly needs to be considered due to the countrys socioeconomic, political and demographic factors, besides the process of redefining family as a social institution. In this way, research regarding the domestic organization and the social support network, meets the questions related to elderly care at home, especially the elder elderly. It is an epidemiologic cross-sectional study, which aimed to characterize the domestic organization and the social support network of the elder elderly living in Ribeirão Preto, SP, as well as its functionality. The sample was made of 147 elderly. Data were collected in interviews at home, using the social identification and profile, the Minimum Map of Elderly Relations (MMRI) to investigate the support network, the Functional Independence Measure (MIF) and questions about the domestic organizations. The average age of female elderly was 84,4 years, and male 84,1 years, 63,3% were in the age group 80-84 years, 27,2% between 85- 89 years and 9,5% were 90 years or more. There is a larger number of old widows (91,3%) and illiterates (83,3%). From the total of the elderly, 41,5% receive pension, earn from one to three minimum wages (72,1%) and live in their own house (74,1%). The elderly have 4,08 children and live with 2,8 people. Regarding functionality, the variation of the observed score was equal the possible variation of motor, social cognitive and total MIF, as well as its domains, with average scoring close to full score. Most elderly people (81,6%) was classified under the complete/modified independence category, and 15% as minimum dependence, as the elderly get older they become more dependent (p < 0, 001). There was no statistic significance between total MIF and domestic organization, despite the increasing tendency to live alone as MIF scoring raises. The relation to social support was not significant either. Great part (26,5%) of the elderly lives with the spouse, and 14,3% live alone. More them half of the domiciles (57,1%) are lead by the elderly itself. As the age group increases the number of elderly living with the spouse decreases, and increases the ones living with sons/daughters. Regarding the elderly social support network configuration, there was prevalence of people in the first circle, that is, frequently with emphasis for children and family, for all off the analyzed functions. The average of the number of friends and people from the community for all kinds of support was lower than one, what reinforces family as protector and caregiver of the elderly.

O desenvolvimento tecnológico, o crescimento industrial, o acelerado processo de urbanização e o crescimento populacional transformaram o espaço geográfico brasileiro. Somado à mudança de hábitos e de consumo acarretou e vem acarretando diversos problemas ambientais. O incentivo à troca e o investimento em produtos descartáveis, levaram a um aumento significativo da geração de resíduos sólidos. Tratar e dar um destino adequado à grande quantidade de resíduos tem sido um grande desafio às autoridades brasileiras. Para que haja melhor gestão e gerenciamento dos resíduos sólidos é preciso conhecer o que tem sido gerado, ou seja, qual a quantidade e que tipo de material é descartado. Para bem conhecer essa produção, a melhor maneira é fazer um estudo da geração e composição gravimétrica dos resíduos sólidos através de sua caracterização física. Portanto, a proposta deste trabalho foi fazer um levantamento da geração dos resíduos sólidos domiciliares no município de São Carlos. Essa investigação levou em conta não apenas os resíduos que chegam ao aterro sanitário através da coleta convencional, mas também os que chegam às centrais de triagem através da coleta seletiva, utilizando-se como instrumento principal a sua caracterização física. Na coleta convencional, o número de amostragem compreendeu todos os setores, sendo a massa da amostra obtida por quarteamento. Foi feito uma caracterização no inverno e outra no verão. Destacam-se, nos resultados, o percentual de resíduos sólidos domiciliares, em massa: matéria orgânica (59,08%), papel e papelão (6,44%), tetra pak (0,94%), vidro (1,67%), metal e alumínio (1,31%), plásticos 10,47% (2,84% de plásticos rígidos e 7,63%de plásticos filmes) e outros (20,09%). Observou-se que o percentual de materiais que poderiam ser reintroduzidos no mercado e estão sendo depositados no aterro sanitário, ainda é elevado, considerando a que a coleta seletiva foi introduzida no município em 2002. Na coleta seletiva destacam-se: o papel e papelão, com 47,41%; seguido pelos plásticos, com 21,60% (rígidos - 17,95% e filmes - 3,65%); vidro, 12,25%; metal e alumínio, 7,63% (lata - 1,54% e geral - 6,10%); rejeitos, 5,79% e tetra pak, 5,30%. / The technological development, the industrial growth, the sped up process of urbanization and the population growth had transformed geographic the space brazilian. Added to the change of habits and consumption it caused and it comes causing diverse ambient problems. The incentive to the exchange and the investment in dismissable products, had led to a significant increase of the generation of solid wastes. To treat and to give an adequate destination to the great amount of wastes have been a great challenge to the brazilian authorities. So that it has better management and management of the solid wastes are necessary to know what he has been generated, that is, which the amount and that type of material is discarded. To know this production well, the best way is to make a study of the generation and gravimetrical composition of the solid wastes through its physical characterization. Therefore, the proposal of this work was to make a current survey of the generation of the household waste in the city of Sao Carlos. This inquiry will not only take in account the wastes that arrive at it fill with earth bathroom through the conventional collection, but also the ones that they arrive at the central offices of selection through the selective collection, using itself as main instrument its physical characterization. They stand out, in the results, the percentage of household wastes, in mass: organic matter (59,08%), paper and cardboard (6,44%), tetra pak (0,94%), glass (1,67%), metal and aluminum (1,31%), plastics 10,47% (2,84% of rigid plastics and 7,63% of plastics films) and other (garbage) (20,09%). It was observed that the percentage of materials that could be returned in the market and they are being deposited in the sanitary landfill, it is still high, considering what the selective collection was introduced in the municipal district in 2002. In the selective collection they stand out: the paper and cardboard, with 47,41%; following for the plastics, with 21,60% (rigid - 17,95% and films - 3,65%); glass, 12,25%; metal and aluminum, 7,63% (can - 1,54% and general - 6,10%); garbage, 5,79% and tetra pak, 5,30%.

Micro- generation is the small-scale and localised provision of heat or electricity. Micro-generators have the potential to reduce greenhouse-gas emissions and enhance energy security by providing heat or electricity from either renewable sources, or via the more efficient use of fossil fuels. But this potential is often unquantified or unclear, and hence quantitative information is required concerning both the energetic performance of micro-generators and their ability to provide net reductions in carbon emissions. <br /> In the context of household energy provision in the UK, thermodynamic and related carbon analyses of three micro-generation technologies have been carried out. These studies contribute to the research of the SUPERGEN ‘Highly Distributed Power Systems’ Consortium, which has been addressing a broad range of issues regarding micro-generation. The technologies analysed here are a grid-tied micro-wind turbine (rotor diameter 1.7m, rated power 600 W at 12 m/s), a grid-tied solar photovoltaic array (15 m2, 2.1 kWp mono-crystalline silicon), and a solar hot-water system (2.8 m2 flat-plate collector, direct-feed system). Annual energy outputs were estimated and contextualised against the demands of representative UK households. The overall energy-resource and carbon savings provided by the micro-generators were assessed on the basis that they (partially) displace the established supply systems. Savings were then compared with the energy-resource and carbon ‘debts’ of the micro-generators to determine their net performance. <br /> The displaced energy or carbon payback periods of the micro-generators were estimated to be well within their estimated lifetimes: a maximum 2.5 years for the SHW system, 3.1 years for the micro-wind turbine installed in an ‘open’ environment, and 7.4 years for the solar PV system. After payback, net energy-resource and carbon savings accrue. This thesis thus demonstrates that, given appropriate UK installations, all three micro-generators can reduce carbon emissions and enhance energy security by reducing use of, and dependence upon, fossil fuels.

Realizou-se um estudo quantitativo com delineamento descritivo e comparativo. A amostra foi constituída por 286 sujeitos casados ou em união estável com filhos de 0 a 18 anos. Os participantes responderam individualmente ao protocolo on line constituído por um questionário sócio demográfico, a Escala Marital Inventory Communication, a Escala Dutch Marital Satisfaction and Communication Questionnaire, Escala de Avaliação da Coesão e Adaptabilidade Familiar, e a Escala de Ajustamento Diádico. Esta dissertação está organizada na forma de dois artigos empíricos: “Comunicação conjugal em diferentes etapas do ciclo de Vida e “Padrões de Comunicação conjugal em homens e mulheres.” Os resultados encontrados indicam que a conjugalidade se sobrepõe a parentalidade, visto que a idade dos filhos não teve interferência na comunicação, e também pontuam que homens e mulheres se comunicam de formas iguais, mas cada um com sua especificidade. Estes achados apontam que as variáveis estudadas têm grande importância para o estudo das relações conjugais e para o entendimento deste fenômeno. / The aim of this dissertation is to evaluate communication (communication levels and styles) between spouses with different levels of functionality (adjustment, cohesion and adaptability) in different stages of marital life cycle (toddlers, school age, teenagers). A quantitative study with descriptive and comparative design was held. The sample was composed by 286 married people or in a common law marriage with children aged between 0 and 18 years old. The participants answered the online protocole individually composed by a socio-demographic questionnaire, the Marital Inventory Communication Scale, Dutch Marital Satisfaction Scale, Communication Questionnaire, Family Adaptability and Cohesion Evaluation Scale, Dyadic Adjustment Scale. This dissertation is organized in a frame of two empirical articles: “Marital Communication in different stages of life cycle” and “Positive and Negative Communication: Differences between men and women”. The found findings point that the studied variables have great importance to the study of conjugal relationships and for the clinical understanding of this phenomenon.
