Abstract (sommario):
De quoi sont faites les monnaies nationales ? Comment décrire ces entités étranges que sont le franc, le dollar ou le yen ? Leur existence tangible et familière nous est donnée sous la forme de pièces métalliques ou de billets de banque. Mais ces objets, tout comme l'ensemble des instruments de paiements (chèques, cartes, etc.), n'ont d'existence monétaire qu'en tant qu'ils expriment une certaine quantité de l'unité de compte nationale. C'est donc en réfléchissant à partir de cette mesure monétaire, et de ce qui la rend si particulière, qu'on peut tenter d'éclairer le problème. En théorie, la mesure monétaire possède la même universalité que les cinq formes de mesure physique (longueur, surface, volume, masse et durée) à cette différence près que la qualité qu'elle nombre, la valeur, est strictement abstraite et sociale, et qu'elle ne prend ainsi corps que dans des espaces socio-politiques déterminés.

Abstract (sommario):
Dans la région d’Aboisso, en zone forestière au Sud-Est de la Côte d’Ivoire, les gîtes de développement larvaire de Simulium damnosum s. l. (Theobald, 1903) ont été prospectés, géoréférencés et les sites sentinelles pour les activités programmatiques d’arrêt de distribution de masse de l’Ivermectine en vue de l’élimination de l’onchocercose, ont été identifiés. Les principaux fleuves de la région (Bia, Eholié, Noé), ont été préalablement repérés sur des cartes (1/200 000, 1/800 000). Les endroits visités ont été géoréférencés. Ils proviennent des enquêtes menées auprès des populations, ainsi que de l’analyse des données épidémiologiques des services de la Santé. Les gîtes pré-imaginaux ont été photographiés, puis prospectés. Les larves et les nymphes collectées ont été identifiées à l’aide de clé. Les gîtes répertoriés ont été classés en quatre catégories : positifs (23%), productifs (23%), noyés (34%) et négatifs (20%). Au total, 2555 stades pré-imaginaux de simulies (2063 larves, 492 nymphes) ont été prélevés. Simulium damnosum s. l. et trois autres espèces (Simulium adersi, Simulium agreavesi, Simulium unicornutum) ont été identifiées. Simulium damnosum s. l. est majoritaire (64,58%) et abonde dans les gîtes du fleuve Bia au niveau des localités de Biaka et de Bianouan, ainsi que dans ceux de Noé à Kotoka. Ailleurs (Boigné, Lingué), la densité est faible. Ainsi à Aboisso, Simulium damnosum s.l. présente de nombreux gîtes de développement. Biaka, Bianouan et Kotoka qui sont situés à proximités des gîtes, apparaissent comme les sites sentinelles de la région, dans le cadre de l’élimination de l’onchocercose en Côte d’Ivoire.

Abstract: Relationship between body mass index (BMI) and dental caries in children has been studied in several countries and shows varying results. Poor dental and oral health will have an impact on several aspects of the quality of life of children such as speaking and chewing, resulting in malnutrition and undernutrition. Meanwhile, intake of foods rich in carbohydrates is a risk factor for overweight or obesity, and can also cause caries. This study aimed to review the relationship between BMI and caries prevalence in children. This was a literature review study using databases obtained from Google Scholar, ScienceDirect, SpringerLink with related topics. The results showed that there were five literatures that showed no relationship between BMI and the incidence of caries in children. One literature stated that a high BMI was significantly associated with a lower probability of caries occurrence. In conclusion, there was no relationship between body mass index and caries prevalence in children, albeit, a literature stated that a higher BMI was associated with a lower chance of caries. Keywords: body mass index; caries; DMF-T index; children with caries Abstrak: Hubungan antara indeks massa tubuh (IMT) dan karies gigi pada anak telah diteliti di beberapa negara dan menunjukkan hasil bervariasi. Kesehatan gigi dan mulut yang buruk akan berdampak pada aspek kualitas hidup anak seperti bicara dan mengunyah sehingga menyebabkan malnutrisi atau kekurangan gizi. Asupan makanan kaya karbohidrat yang merupakan salah satu faktor risiko terjadinya kelebihan berat badan atau obesitas juga dapat menyebabkan terjadinya karies. Penelitian ini bertujuan untuk menelaah dan mengkaji hasil-hasil penelitian terpublikasi sebelumnya yang berkaitan dengan IMT dan prevalensi karies pada anak serta hubungan antara IMT dengan prevalensi karies pada anak. Penelitian ini berbentuk suatu literature review menggunakan dari Google Scholar, ScienceDirect, dan SpringerLink dengan topik yang berhubungan. Hasil penelitian mendapatkan lima literatur yang secara statistik menunjukkan tidak terdapat hubungan antara IMT dengan tingkat kejadian karies pada anak. Satu literatur secara bermakna menyatakan IMT tinggi dikaitkan dengan kemungkinan kejadian karies yang rendah. Simpulan penelitian ini ialah tidak terdapat hubungan bermakna antara IMT dan status karies namun terdapat literatur yang menyatakan IMT lebih tinggi dikaitkan dengan kemungkinan karies yang lebih rendah.

Abstract (sommario):
Abstract: Body mass index (BMI) is a measurement to assess nutritional status. Excessive sugar consumption can result in obesity and dental caries. Fishermen have a risk of dental caries due to their habit of consuming food and drink that contain sugar (cariogenic) to stay awake at night. This study aimed to analyze the relationship between BMI and dental caries status among fisherman in Manado. This was a descriptive and analytical study with a cross-sectional design using the total sampling technique. The normality of the research data was tested using Kolmogorov-Smirnov test and the correlation between variables was analyzed using the Pearson correlation test. The result obtained 51 fishermen of Komunitas Nelayan Dego-Dego Pantai Los selected based on inclusion and exclusion. Majority of subjects had the characteristics of late adolescence with an age range of 17-25 years (33.3%), good oral hygiene index simplified (52.9%), frequency of brushing teeth twice daily (76.5%), were overweight (39.1%) and very high DMF-T index (72.5%). The correlation test obtained a p-value of 0,032 and an r-value of 0.300 which indicated a significant relationship between BMI and dental caries and a weak correlation between the two variables. In conclusion, there is a relationship between BMI and dental caries in fisherman of Komunitas Nelayan Dego-Dego Pantai Los in Manado. Keywords: body mass index; dental caries status; fishermen Abstrak: Indeks massa tubuh (IMT) merupakan pengukuran untuk menilai status gizi seseorang. Konsumsi gula berlebihan dapat menyebabkan terjadinya obesitas dan juga karies gigi.

Abstract (sommario):
Este trabalho tem por objetivo analisar duas imagens – cartões postais – do município de Pelotas no início do século XX, relacionadas aos espaços de sociabilidade da cidade. No final do século XIX e início do XX, Pelotas era o maior centro charqueador do Brasil vivendo
um período de riqueza econômica e cultural. Essa situação possibilitou uma modernização do espaço urbano, com a criação de novos locais de convivência social. Os cartões-postais auxiliam na memória da cidade, impressa nessa narrativa, no período em que o cartão-postal
era o principal meio de comunicação visual de massa. Os postais foram selecionados a partir da disponibilidade desses documentos em acervos privados e dentre aqueles que mostram espaços de sociabilidade de Pelotas. A análise dos cartões postais foi realizada a partir das três
etapas apresentadas por Panofsky (1991): iconografia – pré-iconográfica e iconográfica – e iconologia. As imagens dos cartões postais analisados destacam principalmente o discurso da modernidade, de riqueza e de sofisticada cultura que se traduz na abertura de ruas, praças e jardins. A presença de espaços de sociabilidade nos cartões-postais demonstrava que esses locais estavam relacionados a uma cidade civilizada e moderna, o que Pelotas estava se tornando.

Abstract (sommario):
Resumo Em junho de 1882, Aluísio Azevedo publica, na Gazetinha, duas cartas dirigidas a Giovani, pseudônimo de um leitor (talvez Machado de Assis) que criticara Memórias de um condenado, folhetim impresso por aquele jornal. A Gazetinha não disponibiliza as cartas originais, e o nome de seu autor permanece sem identificação, sugerindo a aspiração de Giovani à privacidade. Aluísio, contudo, ignora a sugestão, discutindo as ideias de Giovani com o fito de justificar a situação dos escritores brasileiros que, como ele, se dividem entre a criação de obras inovadoras e sintonizadas com o presente, e a aceitação das imposições do mercado, que favorece o consumo de literatura de massa.

Abstract (sommario):
RESUMO Neste artigo, analiso um conjunto de seis cartões comerciais pertencentes a uma duradoura campanha de marketing da Liebig Extract of Meat Co. A análise crítica dos textos promocionais produzidos na virada do século XX oferece insights significativos sobre os mecanismos discursivos que contribuíram para a hegemonização do capitalismo burguês. Diferentemente de outras formas de publicidade, os cartões comerciais não são rapidamente descartados e esquecidos; pelo contrário, eles podem se distanciar dos produtos anunciados para se tornar parte dos discursos populares de instrução em massa. Como produtos e produtores de ideologias capitalistas, os anúncios são um local privilegiado de inscrição do capitalismo e, portanto, se prestam a uma análise crítica. Minha análise mostra como os textos selecionados se baseiam e texturizam os discursos do progresso, impregnados como crenças colonialistas e desencadeando uma cadeia de ações pela qual, mesmo antes de realmente obterem os cartões, são promulgadas ações e crenças capitalistas.

Abstract (sommario):
Foram avaliados os hábitos e comportamentos alimentares de adolescentes do sexo feminino com sintomas de anorexia nervosa de uma escola particular. Foi identificada a presença de sintomas através do "Teste de Atitudes Alimentares". O recordatório de 24 horas "modificado" foi usado para avaliar os alimentos consumidos e um questionário foi aplicado para investigar as preferências e aversões alimentares. Das 279 alunas estudadas, 21,1% apresentaram sintomas. Os alimentos mais consumidos entre estas estudantes foram frutas, hortaliças, leite desnatado e bala, e os menos consumidos foram refrigerante, chocolate, massa e batata frita. Os alimentos de que "mais gostam" foram, em ordem decrescente: massas, carnes, hortaliças e doces; e os de que "menos gostam" foram: hortaliças, carnes e gorduras. Houve aversão maior por doces nas adolescentes com sintomas de anorexia nervosa. Concluiu-se ter havido um alto número de alunas com sintomas apresentando aversões alimentares semelhantes às de anoréxicas.

Remy, Benjamin. "Generative modeling for weak lensing inverse problems". Electronic Thesis or Diss., université Paris-Saclay, 2023. http://www.theses.fr/2023UPASP163.
Abstract (sommario):
Le lentillage gravitationnelle, qui génère un effet de déformation des images de galaxies lointaines à travers l'influence de densités de matières massives dans la ligne de visée, est très prometteur pour répondre aux questions relatives à la matière noire et à l'énergie sombre. Cet effet permet de sonder directement la distribution de matière noire dans l'Univers, qui est invisible autrement. Dans le régime où ces déformations sont faibles, il est possible de cartographier la distribution de matières projetées dans la ligne de visée, appelée carte de masse, à partir de la mesure de la déformation d'un grand nombre de galaxies. Cependant, la reconstruction de ces cartes de masse est un problème inverse qui est mal posé, à cause de données manquantes et de bruits dans le signal mesuré, et nécessite donc de l'information à priori pour être résolu. L'objectif principal de cette thèse est d'utiliser les récentes avancées sur les modèles génératifs qui permettent de modéliser des distributions complexes dans des espaces de très haute dimension. Nous proposons en particulier une nouvelle méthode pour résoudre les problème inverses de hautes dimensions et mal posés en en caractérisant la distribution a posteriori complète. En apprenant la distribution a priori à partir de de simulations cosmologiques, nous pouvons reconstruire des cartes de masses de très hautes résolution, y compris aux petites échelles, tout en en quantifiant les incertitudes associées.

En apprenant la distribution a priori à partir de simulations cosmologiques, nous pouvons reconstruire des cartes de masse de très haute résolution, y compris aux petites échelles, tout en en quantifiant les incertitudes associées. De plus, nous présentons une nouvelle méthode de mesure du cisaillement gravitationnel en créant un modèle décrivant les données observées au niveau des pixels. Contrairement aux méthodes standards, cette méthode ne repose pas sur la mesure d'ellipticité des galaxies et introduit donc un nouveau paradigme pour la mesure du cisaillement gravitationnel. Nous proposons en particulier un modèle hiérarchique Bayésien, avec des composantes génératives apprises et des composantes analytiques physiques. Nous montrons que cela permet de résoudre le biais de modèles dans l'estimation du cisaillement gravitationnelGravitational lensing, which is the effect of the distortion of distant galaxy images through the influence of massive matter densities in the line of sight, holds significant promise in addressing questions about dark matter and dark energy. It reflects the distribution of total matter of the Universe and is therefore a promising probe for cosmological models. In the case where these distortions are small, we call it the weak gravitational lensing regime and a straightforward mapping exists between the matter distribution projected in the line of sight, called mass-map, and the measured lensing effect. However, when attempting to reconstruct matter mass-maps under conditions involving missing data and high noise corruption, this linear inverse problem becomes ill-posed and may lack a meaningful solution without additional prior knowledge. The main objective of this thesis is to employ recent breakthroughs in the generative modeling literature that enable the modeling of complex distribution in high-dimensional spaces. We propose in particular a novel methodology to solve high-dimensional ill-posed inverse problems, characterizing the full posterior distribution of the problem. By learning the high dimensional prior from cosmological simulations, we demonstrate that we are able to reconstruct high-resolution 2D mass-maps alongside uncertainty quantification. Additionally, we present a new method for cosmic shear estimation based on forward modeling of the observation at the pixel level. This represents a new paradigm for weak lensing measurement as it does not rely on galaxy ellipticities anymore. In particular, we propose to build a hybrid generative and physical hierarchical Bayesian model and demonstrate that we can remove the source of model bias in the estimation of the cosmic shear

Abstract (sommario):
L'effet de lentille gravitationnelle, qui se traduit par une deformation des images nous parvenant de galaxies lointaines, constitue l'une des techniques les plus prometteuse pour répondre aux nombreuses questions portant sur la nature de l'énergie sombre et de la matière noire. Cet effet de lentille étant sensible à la masse totale, il permet de sonder directement la distribution de matière noire, qui resterait autrement invisible. En mesurant la forme d'un grand nombre de galaxies lointaines, il est possible d'estimer statistiquement les déformations causées par l'effet de lentille gravitationnelles puis d'en inférer la distribution de masse à l'origine de ces deformations. La reconstruction de ces cartes de masses constitue un problème inverse qui se trouve être mal posé dans un certain nombre de situations d'interêt, en particulier lors de la reconstruction de la carte de masse aux petites échelles ou en trois dimensions. Dans ces situations, il devient impossible de reconstruire une carte sans l'ajout d'information a priori.Une classe particulière de méthodes, basées sur un a priori de parcimonie, s'est révélé remarquablement efficace pour résoudre des problèmes inverses similaires pour un large champ d'applications tels que la géophysique et l'imagerie médicale. Le but principal de cette these est donc d'adapter ces techniques de régularisation parcimonieuses au problème de la cartographie de la matière noire afin de developper une nouvelle generation de méthodes. Nous développons en particulier de nouveaux algorithmes permettant la reconstruction de carte masses bi-dimensionnelles de haute resolution ainsi que de cartes de masses tri-dimensionnelles. Nous appliquons de plus les mêmes méthodes de régularisation parcimonieuse au problème de la reconstruction du spectre de puissance des fluctuations primordiales de densités à partir de mesures du fond diffus cosmologique, ce qui constitue un problème inverse particulièrement difficile a résoudre. Nous développons un nouvel algorithme pour résoudre ce problème, que nous appliquons aux données du satellite Planck.Enfin, nous investiguons de nouvelles méthodes pour l'analyse de relevés cosmologiques exprimés en coordonnées sphériques. Nous développons une nouvelle transformée en ondelettes pour champs scalaires exprimés sur la boulle 3D et nous comparons différentes méthodes pour l'analyse cosmologique de relevés de galaxies spectroscopiquesGravitational lensing, that is the distortion of the images of distant galaxies by intervening massive objects, has been identified as one of the most promising probes to help answer questions relative to the nature of dark matter and dark energy. As the lensing effect is caused by the total matter content, it can directly probe the distribution of the otherwise invisible dark matter. By measuring the shapes of distant galaxies and statistically estimating the deformations caused by gravitational lensing, it is possible to reconstruct the distribution of the intervening mass. This mass-mapping process can be seen as an instance of a linear inverse problem, which can be ill-posed in many situations of interest, especially when mapping the dark matter on small angular scales or in three dimensions. As a result, recovering a meaningful mass-map in these situations is not possible without prior information. In recent years, a class of methods based on a so-called sparse prior has proven remarkably successful at solving similar linear inverse problems in a wide range of fields such as medical imaging or geophysics. The primary goal of this thesis is to apply these sparse regularisation techniques to the gravitational lensing problem in order to build next-generation dark matter mass-mapping tools. We propose in particular new algorithms for the reconstruction of high-resolution 2D mass-maps and 3D mass-maps and demonstrate in both cases the effectiveness of the sparse prior. We also apply the same sparse methodologies to the reconstruction the primordial density fluctuation power spectrum from measurements of the Cosmic Microwave Background which constitutes another notoriously difficult inverse problem. We apply the resulting algorithm to reconstruct the primordial power spectrum using data from the Planck satellite. Finally, we investigate new methodologies for the analysis of cosmological surveys in spherical coordinates. We develop a new wavelet transform for the analysis of scalar fields on the 3D ball. We also conduct a comparison of methods for the 3D analysis of spectroscopic galaxy survey

O resfriamento a vácuo é considerado um método de resfriamento rápido, sendo largamente aplicado em vegetais folhosos, além de ser também empregado para o pré-resfriamento de flores após a colheita. O resfriamento é obtido pela evaporação da água do próprio produto, quando este é submetido a uma baixa pressão em uma câmara hermética. Um dispositivo experimental foi montado para a realização deste trabalho e a aplicação da técnica de resfriamento a vácuo foi avaliada através da realização de três estudos. A influência da taxa de redução de pressão durante o resfriamento a vácuo de cortes de frango cozidos foi investigada no primeiro estudo. Através do controle da taxa de evacuação da câmara de vácuo, por um dispositivo de vazamentos calibrados, a perda de massa foi reduzida em 1,11%. Quando comparado com outros processos de resfriamento a vácuo, onde o controle da taxa de evacuação foi efetuado, o resfriamento a vácuo de cortes de frango cozidos mostrou ser a aplicação mais eficiente quanto à relação decréscimo de temperatura por perda percentual de massa. No segundo estudo foram realizados experimentos com diferentes cortes de carne pré-cozidos, obtendo-se dados que foram utilizados para determinar correlações empíricas entre o produto do coeficiente de transferência de massa e da área total de transferência de massa (kS) com o volume das amostras avaliadas. Os resultados indicaram que a evaporação da água pode ocorrer em todo o volume das amostras, o que é fundamental para a obtenção de resfriamentos homogêneos. A aplicabilidade da técnica para o resfriamento de mexilhões após a etapa de cozimento foi avaliada no terceiro estudo. Os experimentos foram realizados em três diferentes sistemas de resfriamento. Os mexilhões pré-cozidos puderam ser resfriados de 90 a 40ºC em menos de dois minutos. Além disso, os processos de cozimento e de resfriamento podem ser realizados em uma mesma câmara, reduzindo a manipulação do produto. Assim, o resfriamento a vácuo de cortes de carnes cozidos é uma alternativa viável de aplicação industrial, mas que deve ser acompanhada de análises sensoriais do produto resfriado, pois modificações de textura e suculência das carnes foram evidenciadas.

Abstract (sommario):
Previous research in social psychology has suggested that ostracism has a negative impact on SE, and also can affect how much food individuals will consume. Moreover, research in the eating disorders literature shows a negative relationship between self-esteem and eating. As such, the present experiment was designed to merge these two lines of research to examine what causal role, if any, self-esteem plays in men\'s and women\'s food consumption. It was proposed that some individuals should show a lack of self regulation in terms of the type and amount of food eaten following ostracism. It was also predicted that this effect would have some possible moderators. To test this prediction, participants were randomly assigned to either an ostracism or inclusion condition within the computer game Cyberball. Results indicated that the ostracism manipulation did not result in the anticipated decrease in SE status nor did it cause any significant changes in eating behavior. Nevertheless, significant correlations between SE and body dissatisfaction (BD) were observed, as well as between BD and appearance based rejection sensitivity. There were also significant correlations between body mass index (BMI) and BD, as well as between SE and ARS in both genders. There was also a significant correlation between SE and BMI, but only for male participants. Exploratory analyses revealed that there may have been an unforeseen impact of experimenter gender on eating behavior post ostracism such that self presentation may have impacted the manner in which individuals responded to ostracism.

Abstract (sommario):
O presente estudo teve por objetivo comparar a composição da saliva de adolescentes com lesões de cárie ativas com a de jovens livres de lesões de cárie. Doze adolescentes com idade média de 15,2 (desvio padrão = 1,6) anos foram divididos em três grupos de acordo com acometimento pela cárie dentária: Grupo CA - participantes com o mínimo de quatro lesões cariosas cavitadas ativas (n=4), classificadas com os escores 5 e/ou 6 pelo Sistema Internacional de Detecção e Avaliação de Cárie (ICDAS, do inglês International Caries Detection and Assessment System); Grupo MB - adolescentes (n = 4) com pelo menos quatro lesões cariosas iniciais ativas (ICDAS 1 e/ou 2); e grupo CO - composto de participantes sem lesões de cárie ativas (n = 4). Proteínas provenientes de saliva estimulada (20 ?g) foram submetidas a espectrometria de massa e eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE) em três experimentos independentes. Valores densitométricos de quinze bandas de diferentes pesos moleculares dos géis SDS-PAGE foram mensurados e analisados por análise de variância ( p<0,05). Espectrometria de massa foi realizada para identificar e caracterizar o proteoma das bandas que mostraram diferenças em três diferentes géis. A quantificação relativa consistiu na realização de eletroforese SDS-PAGE contendo proteínas salivares dos grupos MB e CO pareadas lado a lado de acordo com a concentração de proteínas total. As bandas foram analisadas densitometricamente e as proteínas nelas contidas foram também quantificadas por espectrometria de massa. Resultados encontrados na análise com SDS-PAGE revelaram que quatro bandas de alto e baixo peso molecular do grupo MB se mostraram estatisticamente quando comparadas ao grupo CO. As amostras do grupo CA não mostraram diferenças na comparação ao grupo CO. A análise por espectrometria de massa revelou o conteúdo proteico das amostras de saliva e das bandas eletroforéticas dos géis SDS-PAGE que demonstraram diferenças. A análise quantitativa relativa mostrou as diferenças entre os grupos nas bandas de alto, médio e baixo pesos moleculares, bem como das proteínas nelas presentes. Este estudo concluiu que existem diferenças na composição proteômica da saliva de adolescentes acometidos por cárie quando comparados a jovens sem lesões ativas, principalmente quando se considerou lesões de cárie iniciais.This study aimed to compare the salivary protein content of adolescents presenting active caries lesions with caries-free persons. Twelve adolescents with average age of 15.2 (standard deviation=1.6) years old were divided into three groups according to the caries occurrence: Group CA - participants with at least four active cavitated caries lesions (n = 4), classified as scores 5 and/or 6 according to the International Caries Detection and Assessment System (ICDAS); Group MB - adolescents (n = 4) in which subjects showed at least four cavitated active lesions (ICDAS 5 and 6), group MB (n=4) with at least four active initial caries lesions (scores 1 and/or 2 of ICDAS); and group CO - with subjects with no active caries lesions (n = 4). Proteins from stimulated saliva (20 ?g) were submitted to sodium-dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) in three independent experiments. Densitometric values from fifteen bands of different molecular weights were measured and analyzed with analysis of variance (p<0.05). Mass spectrometry was used to identify and characterize the proteome from electrophoretic bands. Relative quantification consisted in submit to SDS-PAGE salivary protein samples paired by total protein concentration from groups MB and CO. Electrophoretic bands were densitometrically analyzed, and their protein content were quantified with mass spectrometry. Results from SDS-PAGE revealed that four bands of high and low molecular weight from group MB were statistically higher when compared to group CO. Samples from group CA did not show differences when compared to group CO. Mass spectrometry showed the protein content from SDS-PAGE electrophoretic bands. Relative quantitative analysis showed differences among groups in bands of high, middle and low molecular weights, as well in their proteins. This study concludes that there are differences in the proteomic composition of saliva from adolescents with active caries lesions when compared to persons with no active caries lesions, mainly considering initial active caries lesions.

Resumo: Este estudo transversal objetivou investigar a relação entre o estado nutricional, cárie dental, exposição diária ao açúcar e fatores sociais, assim como a presença de biofilme visível em 303 pré-escolares de 3 a 5 anos da cidade de Teresina-PI. A cárie dental foi determinada por meio do critério da Organização Mundial de Saúde (OMS) incluindo lesões iniciais de mancha branca (LMB). O peso e altura corporais foram mensurados e o Índice de massa corporal (IMC) obtido foi plotado em diagrama segundo gênero e faixa etária para obter-se o ranking do percentil segundo o Centers for Disease Control and Prevention (CDC). Os dados de exposição diária ao açúcar (líquido, sólido e total) foram obtidos pelo diário de dieta, usando-se a média de exposição diária de 72 horas. A presença de biofilme dental clinicamente visível nos incisivos superiores foi também registrada. Os fatores comportamentais e socioeconômicos foram coletados por meio de uma entrevista com as mães ou responsáveis pelas crianças. Os dados foram analisados por meio do teste qui quadrado seguido de regressão logística múltipla (? = 0,05, intervalo de confiança = 95%). Os resultados mostraram que 10,6% das crianças eram malnutridas, 17,2% tinham baixo peso, 44,9% apresentaram peso normal, 15,5% tinham sobrepeso e 11,9% eram obesos; 24,8% estavam livres de cárie e 75,2% apresentavam cárie precoce da infância (CPI). A média do ceo-s + LMB foi 10,8 (+ 11,2). Crianças com experiência de cárie apresentaram 0,3 mais chance de serem obesas do que aquelas livres de cárie (p = 0,0049). Da mesma forma, aquelas que consumiam líquidos açucarados mais de 2 vezes por dia apresentaram 2,7 mais chance de serem obesas (p = 0,0339). Nenhuma associação foi encontrada ente cárie e sobrepeso (p = 0,3640) e a presença de biofilme dental (p= 0,3190). Crianças que apresentaram o hábito de dormir com a mamadeira mostraram 2,3 vezes mais chance de terem baixo peso do que aquelas sem esse hábito (p = 0,0174). O gênero feminino apresentou a probabilidade 0,3 vezes maior de serem malnutridas do que o masculino (p = 0,00797). Além disso, pré-escolares com a presença de biofilme dental tiveram 3,1 vezes mais chance de serem malnutridas do que aquelas sem biofilme visível (p = 0,0247). Este estudo mostrou que houve relação entre experiência de cárie, consumo de líquidos açucarados e obesidade. Também mostrou relação entre o uso da mamadeira noturna e baixo peso na infância. Fatores socioeconômicos não foram relacionados ao estado nutricional da criança
Abstract: This cross-sectional study aimed to investigate the relationship among body mass index (BMI), dental caries, sugar exposure and social factors, as well as the presence of visible biofilm in 303 three-to-five-year-old preschoolers in the city of Teresina-PI, Brazil. Dental caries was recorded according to the World Health Organization criteria (WHO) + early caries lesions (ECL). Body weight/height was determined and BMI was calculated. Data regarding the sugar exposure was recorded using the mean exposure of 72-hour recall diet frequency chart. The presence of clinically visible dental biofilm on maxillary incisors was also recorded. Behavioral and social economic status of the study subjects were assessed using an interview applied to the mother. Data were analyzed by chi-square test followed by multiple logistic regression analysis (? = 0.05, confidence interval = 95%). The results showed that 10.6% of the children were malnourished, 17.2% were underweight, 44.9% had health weight, 15.5% were at risk of overweight, and 11.9% were obese; 24.8% were caries free and 75.2% had early childhood caries (ECC). The mean dmfs score was 10.8 (± 11.2). Preschool children with ECC were 0.3 times more likely to be obese than caries free children (p = 0.0049). In the same way, those who consumed liquid sugar more than 2 times a day, were 2.7 times more likely to be obese (p = 0.0339). No association was found between overweight and caries (p=0.3640) and dental biofilm (p= 0.3190). Preschool children who slept with a bottle were 2.3 times more likely to have underweight than children who did not sleep with a bottle (p = 0.0174). Female preschool children were 0.3 times more likely to be malnourished than boys (p = 0.00797). Moreover, preschool children with presence of dental biofilm were 3.1 times more likely to be malnourished than children with absent biofilm (p = 0.0247). In conclusion, our results suggest that preschool children having early childhood caries and a high liquid sugar consumption were more likely to be obese and those who were bottle fed during the night showed a higher chance of having underweight

Abstract (sommario):
Introduction: Childhood obesity and dental caries (DC) have increased worldwide and are continuing to pose challenges to public health. The increasing risk of obesity for children is of particular concern because research has suggested that childhood obesity predicts adult obesity. Children experiencing DC early in their lives have a much greater probability of subsequent caries in their permanent dentitions and adulthood. Studies have reported a strong association between the nutritional intake and DC and reported a direct link between DC, sugar consumption and obesity. Objectives: to assess the association between dental caries (DC), the Body Mass Index (BMI) and diet among grade six learners at selected primary schools in Tshwane West District. Methods: A cross-sectional analytical study of grade six learners was carried out in Tshwane. The data collection consisted of a questionnaire, clinical oral examination and anthropometric measurements. All clinical data was collected by a single calibrated examiner. A validated questionnaire was used to collect the demographic data and the type of diet consumed. The SPSS version 23 software was used for analysis. Descriptive statistics, Chi-Square test to test for significance for categorical data and logistic regression analysis were used to determine statistical significance. Results: The response rate was 83% (440) and of these 53% were male. The mean age of the participants was 11.8yrs. The majority of the participant’s fathers (71%) and 50% of mothers were employed. The DC prevalence was 43% with a mean DMFT score of 1.19 (SD= ±1.79). The PUFA score was zero. Less than half (47%) of the participants reported to brush their teeth twice daily. The majority (71%) claimed to drink between one and one and a half glasses of sugar-sweetened beverages (SSBs) with 67% eating between one and three sweets per day. While most of the participants reported having a balanced meal at supper, a third reported eating junk food. The majority (71%) of participants had a BMI score that was within the normal range with 19% being overweight. There were no significant associations between the mean DMFT, BMI scores and the SES of the participants. Conclusion: The DMFT was low, but the decayed component was relatively high. The PUFA score was zero. Most participants were classified as having a “normal” BMI with almost a quarter being classified “overweight”. There were no significant associations between the DMFT and the mean BMI scores and SES of the learners. More than half of the participants were from a medium SES and had a slightly high DMFT score than their counterparts. Less than half reported to brush their teeth daily, most of them had a balanced diet at supper.Dissertation (MChD)--University of Pretoria, 2017.

Abstract (sommario):
Les régions polaires représentent actuellement les régions mondiales où les changements liés au réchauffement climatique se manifestent de manière particulière et souvent spectaculaire. Notre capacité actuelle à comprendre les modes naturels de la variabilité climatique dans ces zones, ainsi que les impacts directs ou indirects de l'activité anthropique sur ces modes, reste encore relativement limitée. Ainsi, la nappe glaciaire Antarctique et ses composantes (atmosphère, océan, glace de mer) restent encore mal représentées dans les modèles climatiques actuels, contribuant notamment à de fortes incertitudes sur les projections climatiques futures et l'évolution associée du niveau des océans. La poursuite des études sur l'équilibre ou non (et l'évolution future) du bilan de masse (surface et total) des différents secteurs du continent Antarctique, par rapport au réchauffement climatique actuel, s'avère donc primordiale. Dans le cadre de ce manuscrit, je propose de contribuer à réduire les incertitudes du Bilan de Masse de Surface (BMS) Antarctique, permettant d'aborder une optimisation de la cartographie actuelle de ce dernier que ce soit avec les modèles climatiques ou les cartes d'interpolation de BMS.

The polar zones are, at the moment, the world areas where the climatic changes appear in a spectacular way, and this reinforces the necessity of a better understanding of the total and surface mass balance of the ice sheets. Indeed, the Antarctic mass balance (surface and total), is not well known yet and is not correctly represented in current climatic models; this matter of fact contributes to strong uncertainties about future climate projection as well as associated potential contribution on sea level change. As a consequence, the continuation of studies on total and surface mass balance (and future change) in the different Antarctic regions, in response to the actual (and future climate), appears essential. In the framework of the present manuscript, I propose to reduce uncertainties in the Antarctic surface mass balance (SMB) estimates, inducing the possibility to optimize the reconstruction of the accumulation parameter over the continent with atmospheric general circulation (climatic) models and interpolation maps of in situ observations

Abstract (sommario):
Abstract In August 1860, the royal image became photographic. John Edwin Mayall, a leading Regent Street photographer, was permitted to publish his Royal Album. Consisting of fourteen carte-de-visite portraits of Victoria, Albert, and their children, Mayall’s venture was a phenomenal success. A general mania for celebrity cartes, with the Royal Album at its forefront, heralded the beginning of a turbulent relationship between mass culture, photography, and the royal family. The development of photography initiated a dynamic that has been responsible for much subsequent media coverage of the British monarchy. The carte was instrumental in exacerbating the expectation that the royal family would have a publicized existence.

Abstract (sommario):
This paper considers the use of a chain of translating carts or housings having internally rotating eccentric masses in order to accomplish vibration isolation. First a single degree-of-freedom system is harmonically excited to uncover the qualitative behavior of each rotating mass. The simple model is then expanded into a chain of housings, containing rotating eccentric masses, which are interconnected with springs. The internal rotating eccentric masses are damped along their circular pathway by means of linear viscous damping. Due to the lack of elastic or gravitational constraint on the rotating eccentric masses, they provide a nonlinear inertial coupling to their housings. Previous research has shown that such systems are capable of reducing shock or impulsive loading by converting some of the translational kinetic energy into rotational kinetic energy of the internal masses. This paper examines the potential for vibration isolation of a chain of such systems subjected to persistent, harmonic excitation. It is seen that the dynamics of these systems is very complicated, but that trends are observed which have implications for practical isolation systems. Using simulation studies, tradeoffs are examined between displacement and transmitted force for a range of physical parameter values.

Abstract (sommario):
Thus far in reporting the findings of our project “Fifty Years After: Black Employment in the United States Under the Equal Employment Opportunity Commission,” our analysis of what has happened to African American employment over the past half century has documented the importance of manufacturing employment to the upward socioeconomic mobility of Blacks in the 1960s and 1970s and the devastating impact of rationalization—the permanent elimination of blue-collar employment—on their socioeconomic mobility in the 1980s and beyond. The upward mobility of Blacks in the earlier decades was based on the Old Economy business model (OEBM) with its characteristic “career-with-one-company” (CWOC) employment relations. At its launching in 1965, the policy approach of the Equal Employment Opportunity Commission assumed the existence of CWOC, providing corporate employees, Blacks included, with a potential path for upward socioeconomic mobility over the course of their working lives by gaining access to productive opportunities and higher pay through stable employment within companies. It was through these internal employment structures that Blacks could potentially overcome barriers to the long legacy of job and pay discrimination. In the 1960s and 1970s, the generally growing availability of unionized semiskilled jobs gave working people, including Blacks, the large measure of employment stability as well as rising wages and benefits characteristic of the lower levels of the middle class. The next stage in this process of upward socioeconomic mobility should have been—and in a nation as prosperous as the United States could have been—the entry of the offspring of the new Black blue-collar middle class into white-collar occupations requiring higher educations. Despite progress in the attainment of college degrees, however, Blacks have had very limited access to the best employment opportunities as professional, technical, and administrative personnel at U.S. technology companies. Since the 1980s, the barriers to African American upward socioeconomic mobility have occurred within the context of the marketization (the end of CWOC) and globalization (accessibility to transnational labor supplies) of high-tech employment relations in the United States. These new employment relations, which stress interfirm labor mobility instead of intrafirm employment structures in the building of careers, are characteristic of the rise of the New Economy business model (NEBM), as scrutinized in William Lazonick’s 2009 book, Sustainable Prosperity in the New Economy? Business Organization and High-Tech Employment in the United States (Upjohn Institute). In this paper, we analyze the exclusion of Blacks from STEM (science, technology, engineering, math) occupations, using EEO-1 employment data made public, voluntarily and exceptionally, for various years between 2014 and 2020 by major tech companies, including Alphabet (Google), Amazon, Apple, Cisco, Facebook (now Meta), Hewlett Packard Enterprise, HP Inc., Intel, Microsoft, PayPal, Salesforce, and Uber. These data document the vast over-representation of Asian Americans and vast under-representation of African Americans at these tech companies in recent years. The data also shine a light on the racial, ethnic, and gender composition of large masses of lower-paid labor in the United States at leading U.S. tech companies, including tens of thousands of sales workers at Apple and hundreds of thousands of laborers & helpers at Amazon. In the cases of Hewlett-Packard, IBM, and Intel, we have access to EEO-1 data from earlier decades that permit in-depth accounts of the employment transitions that characterized the demise of OEBM and the rise of NEBM. Given our findings from the EEO-1 data analysis, our paper then seeks to explain the enormous presence of Asian Americans and the glaring absence of African Americans in well-paid employment under NEBM. A cogent answer to this question requires an understanding of the institutional conditions that have determined the availability of qualified Asians and Blacks to fill these employment opportunities as well as the access of qualified people by race, ethnicity, and gender to the employment opportunities that are available. Our analysis of the racial/ethnic determinants of STEM employment focuses on a) stark differences among racial and ethnic groups in educational attainment and performance relevant to accessing STEM occupations, b) the decline in the implementation of affirmative-action legislation from the early 1980s, c) changes in U.S. immigration policy that favored the entry of well-educated Asians, especially with the passage of the Immigration Act of 1990, and d) consequent social barriers that qualified Blacks have faced relative to Asians and whites in accessing tech employment as a result of a combination of statistical discrimination against African Americans and their exclusion from effective social networks.

Abstract (sommario):
In the decade after the Civil Rights Act of 1964, African Americans made historic gains in accessing employment opportunities in racially integrated workplaces in U.S. business firms and government agencies. In the previous working papers in this series, we have shown that in the 1960s and 1970s, Blacks without college degrees were gaining access to the American middle class by moving into well-paid unionized jobs in capital-intensive mass production industries. At that time, major U.S. companies paid these blue-collar workers middle-class wages, offered stable employment, and provided employees with health and retirement benefits. Of particular importance to Blacks was the opening up to them of unionized semiskilled operative and skilled craft jobs, for which in a number of industries, and particularly those in the automobile and electronic manufacturing sectors, there was strong demand. In addition, by the end of the 1970s, buoyed by affirmative action and the growth of public-service employment, Blacks were experiencing upward mobility through employment in government agencies at local, state, and federal levels as well as in civil-society organizations, largely funded by government, to operate social and community development programs aimed at urban areas where Blacks lived. By the end of the 1970s, there was an emergent blue-collar Black middle class in the United States. Most of these workers had no more than high-school educations but had sufficient earnings and benefits to provide their families with economic security, including realistic expectations that their children would have the opportunity to move up the economic ladder to join the ranks of the college-educated white-collar middle class. That is what had happened for whites in the post-World War II decades, and given the momentum provided by the dominant position of the United States in global manufacturing and the nation’s equal employment opportunity legislation, there was every reason to believe that Blacks would experience intergenerational upward mobility along a similar education-and-employment career path. That did not happen. Overall, the 1980s and 1990s were decades of economic growth in the United States. For the emerging blue-collar Black middle class, however, the experience was of job loss, economic insecurity, and downward mobility. As the twentieth century ended and the twenty-first century began, moreover, it became apparent that this downward spiral was not confined to Blacks. Whites with only high-school educations also saw their blue-collar employment opportunities disappear, accompanied by lower wages, fewer benefits, and less security for those who continued to find employment in these jobs. The distress experienced by white Americans with the decline of the blue-collar middle class follows the downward trajectory that has adversely affected the socioeconomic positions of the much more vulnerable blue-collar Black middle class from the early 1980s. In this paper, we document when, how, and why the unmaking of the blue-collar Black middle class occurred and intergenerational upward mobility of Blacks to the college-educated middle class was stifled. We focus on blue-collar layoffs and manufacturing-plant closings in an important sector for Black employment, the automobile industry from the early 1980s. We then document the adverse impact on Blacks that has occurred in government-sector employment in a financialized economy in which the dominant ideology is that concentration of income among the richest households promotes productive investment, with government spending only impeding that objective. Reduction of taxes primarily on the wealthy and the corporate sector, the ascendancy of political and economic beliefs that celebrate the efficiency and dynamism of “free market” business enterprise, and the denigration of the idea that government can solve social problems all combined to shrink government budgets, diminish regulatory enforcement, and scuttle initiatives that previously provided greater opportunity for African Americans in the government and civil-society sectors.

From Risk and Conflict to Peace and Prosperity: The urgency of securing community land rights in a turbulent world. Rights and Resources Initiative, febbraio 2017. http://dx.doi.org/10.53892/sdos4115.
Abstract (sommario):
Amid the realities of major political turbulence, there was growing recognition in 2016 that the land rights of Indigenous Peoples and local communities are key to ensuring peace and prosperity, economic development, sound investment, and climate change mitigation and adaptation. Despite equivocation by governments, a critical mass of influential investors and companies now recognize the market rationale for respecting community land rights. There is also increased recognition that ignoring these rights carries significant financial and reputational risks; causes conflict with local peoples; and almost always fails to deliver on development promises.
