Questa tesi è composta di tre saggi collegati relativi a povertà, distribuzione del reddito e stato di nutrizione dei bambini in Uganda. Il primo saggio intitolato “Poverty reduction and Income Distribution Impacts of Exogenous Policy Shocks in Uganda: A Social Accounting Matrix Perspective” analizza come e quali settori ed agenti economici sarebbero maggiormente colpiti da shock esogeni di politica economica che abbiano l'obiettivo della crescita economica, distribuzione del reddito e della riduzione della povertà. La metodologia applicata in questo studio è un modello di equilibrio economico generale - il modello del moltiplicatore della Matrice di Contabilità Sociale (SAM)- basato sulla SAM Ugandese del 2002. Il secondo saggio intitolato “Measurement of Multidimensional Child Poverty in Uganda” utilizza indicatori antropometrici ed un indicatore composito della ricchezza famigliare come misure del benessere dei bambini e applica l'approccio del Dual Cutoff e Counting proposto da Alkire e Foster (2007, 2011) per costruire un indice multidimensionale della povertà infantile in Uganda. Il terzo saggio, intitolato “The Relationship Between Maternal Autonomy and Child Stunting in Uganda” utilizza utilizza misure di autonomia femminile quali la libertà di movimento per visitare la famiglia ed i parenti, il potere decisionale nel fare cospicue spese familiari e giornaliere e l'atteggiamento femminile verso l'abuso fisico e verbale per analizzare la relazione tra autonomia femminile e rachitismo infantile in Uganda. I dati per i saggi 2 e 3 provengono dall'Uganda Demographic and Health Survey (UDHS) per l'anno 2006. I risultati dimostrano che il settore immobiliare, agricolo, commerciale e di trasformazione alimentare sono fondamentali in Uganda; 30% dei bambini sono multidimensionalmente poveri e una bassa autonomia materna è associata al rachitismo. / The thesis consists of three interrelated essays on poverty, income distribution and child nutritional status in Uganda. The first essay titled “Poverty reduction and Income Distribution Impacts of Exogenous Policy Shocks in Uganda: A Social Accounting Matrix Perspective” asks, how and which sectors and economic agents would be most affected by exogenous policy shocks that target growth, income distribution and poverty reduction? This is answered by a way of a general equilibrium model - the social accounting matrix (SAM)-based multiplier model based on the 2002 Uganda SAM. The second essay titled “Measurement of Multidimensional Child Poverty in Uganda” uses the anthropometric indicators and a household composite wealth indicator as measures of child well-being and applies the Dual Cutoff and Counting approach proposed by Alkire and Foster (2007, 2011) to construct a multidimensional child poverty index for Uganda. The third essay titled “The Relationship Between Maternal Autonomy and Child Stunting in Uganda” uses direct evidence on measures of women’s autonomy namely, freedom of movement to visit families or relatives, decisionmaking power on making large household and daily purchases, and women’s attitude toward verbal and physical abuse to examine the relationship between maternal autonomy and child stunting in Uganda. Data for essay 2 and 3 were drawn from the Uganda Demographic and Health Survey (UDHS) for the year 2006. Results show that key sectors in Uganda are Real estate, Agriculture, Trade and Food processing industries; 30% of children are multidimensionally poor; and low maternal autonomy is associated with stunting.

Bacterial adhesion is the first step of biofilm formation and in the focus of research interest since several decades. Biofilms cause many problems, sometimes dramatic, for example in health, food packing or waste water purification. Despite of high interest, bacterial adhesion process is only poorly understood yet. In this work, bacterial adhesion was investigated on well-organized and structured model surfaces with various chemistries at molecular scale. For that purpose a characterization methodology was developed to sufficiently analyze monolayers on silicon wafers, and controlled mixed monolayers surfaces with different densities of NH 2 backfilled with CH3 were developed and optimized. These controlled surfaces with different densities of 0 % NH2 up to 100% NH2 were eventually used as tool to study bacterial adhesion in batch and real time conditions. The results demonstrate a significant impact on bacterial adhesion of weak difference in the surface chemistry at molecular scale. In the batch experiments, two so-called "plateaus" zones were determined, in which bacterial adhesion is not significantly different despite the change of the amine concentration on the surface. On the contrary, one transition zone exists between the "plateaus" in which a slight chunge.in the amine concentration leads to a significant increase / decrease of the bacterial adhesion. The same trend of bacteria behavior was observed for different bacterial strains.

Denna uppsats syftar till att ge en bild av förbundet Humanisternas debatt och porträttering av islam och muslimer. Detta med hjälp av utländska ateister som även förekommit i förbundets egen tidskrift Humanisten. Mina frågeställningar är: Hur framställs islam och muslimer av media och av förbundet Humanisterna? Vilken kritik har framförts av Humanisterna angående islam och muslimer? Bidrar förbundet till en ökad schablonisering av islam och muslimer? För att nämna kortfattat vad jag kommit fram till kan det sägas att Humanisterna, när de skriver om islam eller muslimer, delvis är intoleranta i sin retorik. Den kritik som framförts mot förbundet är bland annat att de vill tvinga på en sekulär livsåskådning och att de tror dig ha ett slags monopol på sanningen. Eftersom den mediebild som redan existerar av islam och muslimer är negativt laddad, så hjälper Humanisterna till att öka den bild av islam som finns som den ”onda, mörka” religionen i vår tid, det vill säga, man bidrar till redan existerande schablonisering av muslimer.

The significance of Yesemek Stone Quarry and Sculptural Workshop in Gaziantep Islahiye province is rooted in its basalt quarry and stone sculptures found at the site. Yesemek was first discovered by Felix Von Luschan in 1890 while he was excavating Zincirli (Sam&rsquo / al). Between 1958 and 1961, the site was excavated by a team under the leadership of Prof. Dr. Bahadir Alkim. The excavations at the site yielded approximately three hundred finished or unfinished lion, sphinx and mountain god sculptures. While the exact function of these sculptures are still not known, the thesis will explore the function of these sculptures by examining the architectural structures where the sculptures could have been used as architectural decoration. Another issue that will be discussed in the thesis is the date of Yesemek workshop and sculptures. To that end, Yesemek sculptures will be stylistically compared to Late Bronze and Iron Age sculptures.

<p>This thesis deals with the synthesis of electroactiveorganic compounds. The synthesis of ethylenedioxy-benzodioxinstri-dioxin and tetra-dioxin are described. These molecules wereprepared with the aim of creating donor molecules for cationicradical salts. The symmetric analogs of tri-dioxin,methylenedioxy-derivative and ethylenedioxy-naphthalene werealso synthesized. Three different cation radical salts with 2:1stoichiometries were obtained from tri-dioxin, whiletetra-dioxin merely provided polycrystalline materials.Tri-dioxin and tetra-dioxin were also successful as operationalmatrixes in PALDI-TOF.</p><p>Tetrathiafulvalenes with the2-dialkyl-amino-1,3-dithiolium-4-thiolate mesoion asbuilding-block was also synthesized. A series of doublyalkylthiol-substituted TTFs were prepared with the aim offorming self-assembly monolayers on gold surfaces in theapplication of organic thin film field-effect transistors.Film-formation for two TTFs were studied and they providedrelatively dense packed monolayers with a discrete distance ofthe TTF moiety from the gold surface.</p><p>The mesoionic compound was also for the first time used inan<i>umpolung</i>reaction. The electrophile obtained in situ bytreatment of mesoion with sulfuryl chloride was reacted with avariety of electron-rich aromatic compounds.

<p>Nanofabrication techniques were used to manufacture nanometer scale protein templates. The fabrication approach employs electron beam lithography (EBL) patterning on poly(ethylene glycol) (PEG) thiol (CH3O(CH2CH2O)17NHCO(CH2)2SH) self-assembled monolayers (SAM) on Au. The PEG SAM prevented protein surface adhesion and binding sites for protein were created in the SAM by EBL. Subsequent to EBL, the patterns in the PEG SAM were backfilled with 40-nm NeutrAvidin-coated fluorescent spheres (FluoSpheres). The spontaneous and directed immobilization of the spheres from a solution to the patterns resulted in high resolution protein patterns. The FluoSpheres could be arranged in any arbitrary pattern with ultimately only one or a few FluoSpheres at each binding site.</p><p>Growth dynamics and SAM morphology of PEG on Au were studied by atomic force microscopy (AFM). PEG SAMs on three types of Au with different microstructure were examined: thermally evaporated granular Au and two types of Au films produced by hydrogen flame annealing of granular Au, Au(111) and "terraced" Au (crystal orientation unknown). The different Au surfaces' substructure affected the morphology and mechanical properties of the PEG SAM. On Au(111), AFM imaging revealed monolayer formation through three distinct steps: island nucleation, island growth, and coalescence. The fine-structure of the SAM revealed dendritic island formation - an observation which can be explained by attractive intermolecular interactions and diffusion-limited aggregation. Island growth was not observed on the "terraced" Au.</p><p>AFM studies of EBL patterned PEG SAMs on Au(111) revealed two different patterning mechanisms. At low doses, the pattern formation occurs by SAM ablation in a self-developing process where the feature depth is directly dose dependent. At higher doses electron beam induced deposition of material, so-called contamination writing, is seen in the ablated areas of the SAM. The balance between these two mechanisms is shown to depend on the geometry of the pattern.</p><p>In addition to PEG SAMs, fibronectin monolayers on SiO2 surfaces were patterned by EBL. The areas exposed with EBL lose their functionality and do not bind anti-fibronectin. With this approach we constructed fibronectin templates and used them for cell studies demonstrating pattern dependent cell geometries and cell adhesion.</p>

L’oxydoréduction de monocouches auto-assemblées (SAMs) de ferrocénylalcanethiolates à la surface d’or (FcRSAu) a été étudiée en temps réel par la spectroscopie de résonance de plasmons de surface couplée avec l’électrochimie (E-SPR). La sensibilité de cette technique permet de déterminer des changements d’épaisseur de couche l’ordre de quelques angström résultant d’un changement de structure de la SAM. Plusieurs études antérieures ont proposé que l’oxydation électrochimique d’une SAM de FcRSAu induit une réorientation moléculaire. L’E-SPR est utilisé pour identifier l’origine de ce changement structurel. D’abord, une calibration du réfractomètre SPR utilisé a été effectuée afin de trouver une équation de conversion du signal SPR obtenu en pixel en angle d’incidence pour que l’on puisse calculer le changement d’épaisseur de monocouche à partir du changement d’angle de résonance avec le modèle de Fresnel. Par la suite, une caractérisation approfondie des SAMs de FcCnSAu (où n = 6, 8, 12, 14) en contact avec du NaClO4 acidifié a été réalisée par électrochimie, éllipsométrie, spectroscopie infrarouge et microscopie à force atomique. Les résultats obtenus montrent que l’augmentation de la longueur des chaînes alkyles donne des SAMs de ferrocènes plus épaisses et moins désordonnées. L’analyse par l’E-SPR de ces SAMs pures montre que le changement d’épaisseur induit par l’électro-oxydation dépend linéairement du nombre de méthylènes sur la chaîne alkyle. En appliquant la déconvolution mathématique aux voltampérogrammes cycliques enregistrés pour les SAM mixtes (FcC12SAu/C11SAu) de différentes compositions, on arrive à la conclusion qu’il y a un redressement des chaînes alkyles dans les domaines des ferrocènes agrégés mais la réorientation des têtes de ferrocène dans les domaines de ferrocènes agrégés ou dispersés ne peut pas être exclue. Enfin, l’effet de l’anion électrolytique sur le changement d’épaisseur de la SAM mesuré par l’E-SPR a été étudié. L’analyse électrochimique montre que la capacité de pairage d’anions avec les ferrocéniums décroit comme suit : PF6- > ClO4- > BF4- > NO3-. Tandis que l’épaisseur de la SAM donnée par le changement d’angle de résonance suit la tendance suivante : NO3- ≥ ClO4- > PF6- ≈ BF4-. Des études plus approfondies seront nécessaire pour clarifier cette tendance observée par E-SPR. / The oxidation and reduction of self-assembled ferrocenylalkanethiolate monolayers formed on gold surfaces (FcRSAu) have been followed in real-time by electrochemical surface plasmon resonance (E-SPR) spectroscopy. Film thickness changes on the order of angstroms resulting from SAM structural changes can be detected by SPR. The electrochemically-induced reorientation of the ferrocenylalkanethiolates has been proposed by several spectroelectrochemistry studies. We have used E-SPR to elucidate the nature of the molecular reorientations. The SPR refractometer was first calibrated to find a pixel to angle equation so that Fresnel modeling could be used to calculate SAM thickness changes from the measured resonance angle changes (Δθmin). SAMs of FcCnSAu (where n = 6, 8, 12, 14) were characterized by electrochemistry, infrared spectroscopy and atomic force microscopy. The results obtained show that an increase in the alkyl chain length gives a thicker and less disordered SAM. Oxidation of the surface-bound ferrocenes to ferroceniums and pairing with ClO4- anions produces a similar change in Δθmin for these SAMs, but the variation in the SAM thickness is linearly dependent on the chain length. Mathematical deconvolution of the cyclic voltammograms of binary SAMs (FcC12SAu/C11SAu) of different compositions was used to separate the contributions of the different ferrocene domains (aggregated vs. isolated ferrocenes). We conclude that the aggregated-ferrocenes undergo a change in the orientation of the alkyl chain orientation. We cannot however exclude that the cyclopentadiene rings also reorient themselves. Anion pairing effect was studied by E-SPR. Our electrochemistry results indicate that the ability of the electrolyte anion to pair with the electrogenereted ferrocenium decreases in the following order: PF6- > ClO4- > BF4- > NO3-. On the other hand, the change in Δθmin does not follow the associated trend observed for the anion pairing capacity but rather NO3- ≥ ClO4- > PF6- ≈ BF4-. We hypothesize that the difference in the uptake water molecules by the oxidized SAM may be the reason for this observation. This hypothesis still needs to be verified.

Le travail de recherche présenté ici a été mené dans le cadre du projet global RAUDIN " Recherches Aquitaine sur les Usages pour le Développement des dIspositifs Numériques " et, plus spécifiquement, au sein du sous-projet " indicateurs et mesure ". L'objectif était d'identifier les usages des dispositifs numériques et en particulier ceux dispensés via des applications Web. Il est proposé d'étudier un corpus de sites web d'Aquitaine (en englobant l'organisation éditrice, le résultat d'édition et les clients des sites) afin d'élaborer des indicateurs de performance et de qualité du mode d'édition web. L'objectif de la thèse est de proposer une méthodologie d'évaluation de l'alignement stratégique des sites web à des fins de pilotage pour une meilleure dynamique de compétitivité et d'organisation interne des institutions, de visibilité de leurs publications et, rétroactivement, d'utilisabilité des dispositifs de communication. Au contexte économique actuel caractérisé par une concurrence et une évolutivité toujours plus fortes, les organisations, quelle que soit leur nature, répondent par une augmentation de leur propre complexité pour survivre et s'épanouir. Cette augmentation de la complexité peut facilement conduire à une baisse de la performance si l'organisation n'est pas en mesure de mettre en cohérence toutes ses composantes avec sa stratégie globale. Le site web de l'organisation fait partie de ces composantes. Plus précisément, les sites web sont une vitrine sur l'organisation, ouverte à toute personne ayant accès à internet et ceci partout dans le monde. Outil de communication, le site web est souvent également un outil commercial et s'inscrit donc au cœur de l'activité métier de l'organisation. De plus, le site web se caractérise également par sa dynamique : il évolue constamment en termes de contenu, de fonctions et d'apparence. Cet ensemble de caractéristiques plaide pour l'intégration du site web dans la stratégie de l'organisation. La méthodologie d'évaluation de l'alignement stratégique des sites web que nous proposons est adaptée du modèle SAM (Strategic Alignment Model). Nous identifions dans notre démarche quatre domaines d'analyse : La stratégie d'affaire, la stratégie web, l'infrastructure organisationnelle et le site web lui-même. Deux niveaux de cohérence sont traités : l'ajustement inter-domaines et l'alignement. Le principe général de l'ajustement est de vérifier que deux domaines contigus sont cohérents. Pour cela, les domaines sont caractérisés par un ensemble de paramètres et l'évaluation de la cohérence entre les deux domaines d'analyse est réalisée à l'aide de matrices. Les paramètres de la matrice indiquent le niveau de dépendance entre les caractéristiques des deux domaines d'analyse. La dépendance est évaluée en quatre niveaux : dépendance nulle, dépendance faible, dépendance moyenne et dépendance forte. Nous définissons ainsi quatre matrices, chacune représentative d'un type d'ajustement : ajustement stratégique, ajustement opérationnel, ajustement organisation et ajustement web. L'alignement inter-domaines est défini par la mise en relation de trois domaines parmi les quatre. Huit combinaisons sont ainsi possibles parmi lesquelles quatre sont considérées comme plus pertinentes et connues comme les séquences d'alignement SAM. Ces séquences sont :* l'Exécution de la stratégie qui implique les domaines Stratégie d'affaire, Infrastructure organisationnelle et site web,* la Transformation technologique qui implique les domaines Stratégie d'affaire, Stratégie web et Site web,* le Potentiel compétitif qui implique les domaines Stratégie web, Stratégie d'affaire et Infrastructure organisationnelle,* le Niveau de service du web qui implique les domaines Stratégie web, Processus, Site web et infrastructure organisationnelle.La méthodologie est appliquée à deux cas : L'université Bordeaux 1 et l'Université Bordeaux Segalen.

A novel cyclopentadienylruthenium(II) thiolato Schiff base, [Ru(SC6H4NC(H)C6H4OCH2CH2SMe)(&eta / 5-C2H5]2 was synthesized and deposited as a selfassembled monolayer (SAM) on a gold electrode. Effective electronic communication between the Ru(II) centers and the gold electrode was established by electrostatically cycling the Shiff base-doped gold electrode in 0.1 M NaOH from -200 mV to +600 mV. The SAMmodified gold electrode (Au/SAM) exhibited quasi-reversible electrochemistry. The integrity of this electro-catalytic SAM, with respect to its ability to block and electro-catalyze certain Faradaic processes, was interrogated using Cyclic and Osteryoung Square Wave voltammetric experiments. The formal potential, E0', varied with pH to give a slope of about - 34 mV pH-1. The surface concentration, &Gamma / , of the ruthenium redox centers was found to be 1.591 x 10-11 mol cm-2. By electrostatically doping the Au/SAM/Horseradish peroxidase at an applied potential of +700 mV vs Ag/AgCl, a biosensor was produced for the amperometric analysis of hydrogen peroxide, cumene hydroperoxide and tert-butylhydroperoxide. The electrocatalytic-type biosensors displayed typical Michaelis-Menten kinetics with their limits of detection of 6.45 &mu / M, 6.92 &mu / M and 7.01 &mu / M for hydrogen peroxide, cumene hydroperoxide and tert-butylhydroperoxide respectively.

A novel localized surface plasmon resonance (LSPR) sensor that differentiates between background refractive index changes and surface-binding of a target analyte (e.g. a target molecule, protein, or bacterium) is presented. Standard, single channel LSPR sensors cannot differentiate these two effects as their design allows only one mode to be coupled. This novel technique uses two surface plasmon modes to simultaneously measure surface binding and solution refractive index changes. This increases the sensitivity of the sensor. Different channels or modes can be created in sensors with the introduction of gold nanospheres or gold nanorods that act as receptor mechanisms. Once immobilization was achieved on gold nanospheres, the technique was optimized to achieve the same immobilization for gold nanorods to get the expected dual mode spectrum. Intricate fabrication methods are illustrated with using chemically terminated self assembled monolayers. Then the fabrication process advances from chemically silanized nanoparticles, on to specific and systematic patterns generated with the use of Electron Beam Lithography. Comparisons are made within the different methods used, and guidelines are set to create possible room for improvement. Some methods implemented failed, but there was a lot to learn from these unsuccessful outcomes. Finally, the applications of the dual mode sensor are introduced, and current venues where the sensors can be used in chemical and biological settings are discussed.
