ades and roof. The effect of sun spaces on temperature patterns within case study buildings was determined by collecting internal temperature and humidity data from different locations within the buildings and external temperature and humidity data on certain days of the week from May to August and October and November. Data loggers were used to collect these data. The collected data was then compared for the two buildings and also for the different months. In conclusion, more heat gain resulting in temperature increase inside the buildings was obtained in conservatories when compared to the atria which have glazed faç
ade instead of glazed roof. This was also proved by the analysis of variance method which was used for the comparison of temperature data of two buildings

Testo completoDet primära syftet med denna uppsats är att kartlägga dubbelpassiv-konstruktionens syntaktiska och semantiska natur samt frekvens i det svenska språket. Resultaten visade att dubbelpassiven är en kontrollkonstruktion där det inbäddade verbets interna argument (OBJ) lyfts till positionen som det s-passiva matrisverbets subjekt, och där verbet i infinitivsatsen uttrycks som en s-passiv infinitiv. I uppsatsen används Lexical functional grammar (LFG) som modell för semantisk och syntaktisk analys. Analysen visade att då AGENTEN undertrycks, så skapas en argumentstruktur som får ett equi-verb att framträda som ett raising-verb (jmfr Ørsnes 2006:404). Explicita agenter, i konstruktioner med dubbelpassiver, visade en ännu lägre frekvens än den redan låga frekvens som dokumenterats i tidigare forskning om passiv-konstruktioner av Silén (1997) och Laanemets (2010). Den lägre frekvensen, är delvis ett resultat av faktumet att agenterna i en dubbelpassiv-konstruktion undertrycks två gånger. Resultaten av en korpusstudie visade att frekvensen av explicita agenter, i konstruktioner som innehåller dubbelpassiver, uppgick till 3.57 %. Komplementeraren "att" i den underordnade infinitivsatsen i en dubbelpassiv uttrycks explicit – delvis beroende på matrisverbens modala egenskaper (jmfr. Sundman 1983; Teleman 1999; Lagerwall 1999), samt beroende av grad av semantisk länkning mellan matrisverbet och komplementet (Givón 2001b). Den insamlade datan (matrisverb) i korpusstudien analyserades enligt ett kategoriseringssystem hämtat ur SAG (Teleman et al. 1999), Givón (2001a) och Givón (2001b). Matrisverb med starka nominella (lexikala) egenskaper, till exempel planera, visade en högre frekvens i förekomst med fullständiga infinitivsatser, i jämförelse med mer funktionella matrisverb som avse.

"Efeito da exposição ao tabagismo e da mobilidade social sobre o crescimento e ganho de peso do nascimento à adolescência em uma coorte de base populacional de Cuiabá-MT".

Testo completoEsta tese é composta por três artigos que permitiram avaliar o efeito da exposição ao tabagismo durante a gestação e no início da infância sobre o crescimento linear e ganho de peso do nascimento à adolescência, além de verificar o efeito do nível socioeconômico no início da infância e da mobilidade social sobre a adiposidade até a adolescência. Foram utilizados para este fim os dados de uma coorte de crianças nascidas entre 1994 e 1999 na cidade de Cuiabá-MT. Essas crianças fizeram parte de um estudo de base populacional realizado na cidade de Cuiabá, entre 1999 e 2000, com 2405 crianças (0 a 5 anos) e foram selecionadas aleatoriamente em unidades básicas de saúde quando da vacinação. As mães foram entrevistadas após a vacinação, quando foram obtidos dados relativos à exposição ao tabagismo gestacional, tabagismo passivo, nível socioeconômico das famílias e dados antropométricos. Entre 2009 e 2011, após aproximadamente 11 anos, essas crianças foram localizadas por meio do Censo Escolar e então 1716 adolescentes entre 10 e 17 anos de idade (71,4% da população) foram reavaliados nas escolas da rede pública e privada de Cuiabá, de 18 municípios do estado e outras 5 capitais do país. A análise por modelos lineares de efeitos mistos permitiu verificar a mudança de estatura e Índice de Massa Corporal (IMC) entre o nascimento e a adolescência. O primeiro e o segundo artigo desta tese avaliaram o efeito da exposição ao tabagismo materno durante a gestação e no início da infância sobre o crescimento linear e o IMC entre o nascimento e a adolescência. Crianças expostas ao tabagismo materno durante a gestação e no início da infância apresentaram menor estatura desde o nascimento até a adolescência quando comparadas às crianças não expostas. Quanto à adiposidade, entre o nascimento e a infância a mudança do IMC foi similar entre as crianças expostas e não expostas ao tabagismo materno, porém, entre a infância e a adolescência, aquelas expostas apenas durante a gestação mostraram maior ganho de IMC. Em conjunto, os dados corroboram o efeito deletério do tabagismo sobre o crescimento, efeito já bastante estudado, mas também indicam que avaliar e comparar exposição gestacional com pós-gestacional é importante, dado que seus efeitos parecem ser diferentes. O terceiro artigo avaliou o efeito do nível socioeconômico no início da infância e da mobilidade social entre a infância e a adolescência sobre o IMC do nascimento à adolescência. Para avaliar o nível socioeconômico, as famílias foram classificadas em nível econômico alto, médio e baixo, a partir do Critério de Classificação Econômica Brasil. Foi observada expressiva mobilidade social na população, principalmente entre os de menor nível econômico. Houve maior aumento do IMC entre o nascimento e a adolescência entre aqueles de maior nível econômico na infância e aqueles que permaneceram nas classes mais elevadas, indicando que a posição inicial foi o maior determinante das mudanças observadas no IMC.
This thesis consists of three papers that allowed us to evaluate the effect of exposure to smoking during pregnancy and early childhood on linear growth and weight gain from birth to adolescence, and to verify the effect of socioeconomic position in early childhood and social mobility on adiposity until adolescence. For this purpose, we used the data of a cohort of children born between 1994 and 1999 in the city of Cuiabá. They were part of a population-based study conducted with 2,405 children (05 years) who attended one of the ten basic health units selected for vaccination in the city of Cuiabá between 1999 and 2000. Between 2009 and 2011, after approximately 11 years, these children were located through the School Census; thus, 1,716 adolescents aged 10 to 17 years old (71.4% of the population) were reassessed in the public and private schools of Cuiabá, of 18 counties in the state and five other capitals in the country. The mothers were interviewed after vaccination to obtain data regarding their exposure to smoking during pregnancy, passive smoking, socioeconomic status, and anthropometric information. The linear mixed-effects analysis showed the change in height and body mass index (BMI) from birth to adolescence. The first and second articles in this thesis evaluate the effect of exposure to maternal smoking during pregnancy and early childhood on linear growth and BMI from birth to adolescence. Children exposed to maternal smoking during pregnancy and early childhood were shorter from birth to adolescence than the children not exposed. As for adiposity between birth and childhood, the BMI change was similar between children exposed and not exposed to maternal smoking; however, between childhood and adolescence, those exposed only during gestation showed greater gains in BMI. Together, these data not only confirm the deleterious effect of smoking on growth, which has been extensively studied, but also indicate that it is important to evaluate and compare gestational to post-pregnancy exposure because their effects seem to be different. The third paper examines the effect of socioeconomic status in early childhood and social mobility from childhood to adolescence on BMI from birth to adolescence. To assess socioeconomic position, the families were classified into high, medium, and low economic levels based on the Brazil Criterion of economic classification. We observed significant social mobility in the population, especially among the lower economic group. We observed a greater increase in BMI from birth to adolescence among those from higher socioeconomic position in childhood and those who remained in the higher classes, indicating that the starting position was the major determinant of the observed changes in BMI.

Testo completoBackground: Case-control studies are very often used by epidemiologists to assess the impact of specific exposure(s) on a particular disease. These exposures may be represented by several time-dependent covariates and new methods are needed to accurately estimate their effects. Indeed, conventional logistic regression, which is the standard method to analyze case-control data, does not directly account for changes in covariate values over time. By contrast, survival analytic methods such as the Cox proportional hazards model can directly incorporate time-dependent covariates representing the individual entire exposure histories. However, it requires some careful manipulation of risk sets because of the over-sampling of cases, compared to controls, in case-control studies. As shown in a preliminary simulation study, the optimal definition of risk sets for the analysis of case-control data remains unclear and has to be investigated in the case of time-dependent variables. Objective: The overall objective is to propose and to investigate new versions of the Cox model for assessing the impact of time-dependent exposures in case-control studies, and to apply them to a real case-control dataset on lung cancer and smoking. Methods: I identified some potential new risk sets definitions (the weighted Cox model and the simple weighted Cox model), in which different weights were given to cases and controls, in order to reflect the proportions of cases and non cases in the source population. The properties of the estimates of the exposure effects that result from these new risk sets definitions were investigated through a simulation study. Various aspects of exposure were generated (intensity, duration, cumulative exposure value). The simulated case-control data were then analysed using different versions of Cox’s models corresponding to existing and new definitions of risk sets, as well as with standard logistic regression, for comparison purpose. The different regression models were then applied to real case-control data on lung cancer. The estimates of the effects of different smoking variables, obtained with the different methods, were compared to each other, as well as to simulation results. Results: The simulation results show that the estimates from the new proposed weighted Cox models, especially those from the weighted Cox model, are much less biased than the estimates from the existing Cox models that simply include or exclude future cases. In addition, the weighted Cox model was slightly, but systematically, less biased than logistic regression. The real life application shows some greater discrepancies between the estimates of the proposed Cox models and logistic regression, for some smoking time-dependent covariates. Conclusions: The results suggest that the new proposed weighted Cox models could be an interesting alternative to logistic regression for estimating the effects of time-dependent exposures in case-control studies.
