Full textAbstract:
This study was conducted to identify and analyse Mail and Guardian Online moderation outputs which contradicted the platform‟s own stated policy on hate speech and other forms of problematic speech. The moderation outputs considered were a battery of readers‟ comments that were posted in response to Thought Leader blogs on xenophobia published between May and June, 2008. This was the same period a series of xenophobic attacks was taking place in some parts of South Africa, leaving an estimated 62 people dead, more than 30,000 displaced, and countless victims injured and robbed of their property. The attacks were a catalytic moment that enabled a whole range of discursive positions to be articulated, defended, contested and given form in the media. They also made visible the potential tensions between free speech on the one hand, and hate and other problematic speech on the other. Using qualitative methods of thematic content analysis, document review, individual interviews, and an eclectic approach of framing analysis and rhetorical argumentation, this study found instances of divergence between the M&G policy and practice on User Generated Content. It found that some moderator-approved content advocated hate, hatred, hostility, incitement to violence and/or harm, and unfair discrimination against foreign residents, contrary to the M&G policy which is informed by the constitutional provisions in both section 16 of the Bill of Rights and section 10 of the Equality Act. Based on examples in the readers‟ comments of how „the foreigner‟ was made to signify unemployment, poverty, disease, unfair competition, and all manner of deprivation, and bearing in mind how such individuals have also become a site for the violent convergence of different unresolved tensions in the country, the study‟s findings argue that the M&G – a progressive paper dealing with a potentially xenophobic readership (at least a portion of it) – should have implemented its policy on acceptable speech more effectively. The study also argues that the unjustifiable reference to foreigners as makwerekwere, illegals, illegal aliens, parasites, invaders and border jumpers, among other terms, assigned them a diminished place – that of unwanted foreigner – thereby reproducing the order of discourse that utilises nationality as a space for the expurgation of the „other‟. The study argues that the use of bogus (inflated) immigration statistics and repeated reference to the foreigners‟ supposedly parasitic relationship to the country‟s resources also unfairly constructed them as the „threatening other‟ and potentially justified action against them.

Ces nouvelles activités illustrent au plan technique l'évolution de notre milieu ou le succès des opérations de développement rural dépend de la prise en compte de la perception globale de l'environnement des communautés localesThe general tendency to the increasing of the temperatures and the decreasing of the pluviometry, the deteriorating of soils and vegetal cover show how the physical aspect of the Sankarani and upper Niger valley in Mali is damaged. The building of the selingue dam in that area has allowed hydroelectric generation, irrigated farming and an experimention of a new kind of fishing. These new activities illustrate in the technical field the development of our surroundings from which the success of the rural growth operations takes into consideration the total perception of local communities environment

Full textAbstract:
Le vent de la démocratisation, qui a soufflé en début des années 90 dans la plupart des États africains, a entraîné des changements considérables sur les plans politique, social et administratif. Parmi les préoccupations inscrites à l'agenda politique du moment figuraient les réformes institutionnelles, notamment celles de l'État et de ses démembrements. Cela s'expliquait par la nature profondément dégradée qui caractérisait et caractérise encore les rapports entre l'État et la société. Aussi, cette situation résultait-elle, le plus souvent, directement de la faiblesse des appareils étatiques et des carences d'organisation et d'encadrement qui s'en suivent. En raison du lien filial entre la haute fonction publique et l'État, la réforme de l'une pourrait contribuer à celle de l'autre. Il convient cependant de préciser que la haute fonction publique n'est qu'une sphère de l'État, elle ne saurait donc représenter que l'État administratif. Ainsi, elle doit agir en étroite collaboration avec l'État politique et les instances sociales. Pour ce faire, s'imposent à la fois un enracinement de l'institution dans ses valeurs traditionnelles et son ouverture à certaines valeurs de la nouvelle gestion publique.

Le developpement de l'agriculture a jusqu'alors ete la priorite du gouvernement malien. Celui-ci a cree des institutions pour organiser le monde rural a travers une approche integree : ce sont les operations de developpement rural (oor) dont l'ohv. Depuis leur mise en place, ces odr ont multiplie les initiatives et les strategies pour atteindre les objectifs vises, notamment l'auto-suffisance alimentaire (production de cereales), et l'intensification des cultures de rente (coton et tabac a l'ohv). Malgre des efforts louables, le but n'est pas encore atteint. Les responsables de l'agriculture encouragent la creation d'associations villageoises pour faciliter la realisation des objectifs. De leur cote, les ruraux fondent des espoirs sur ces structures associatives villageoises (av) pensant qu'elles seront aussi utiles que leurs associations traditionnelles, les kare, sere et ton. Ameliorer cet etat de chose suppose, d'une part, une connaissance plus approfondie de la dynamique des structures traditionnelles et du role des acteurs, hommes et femmes, et, d'autre part, une meilleure preparation des paysans aux activites que l'on entend transferer aux av : gestion, vulgarisation agricole, etc. L'alphabetisation fonctionnelle pourrait contribuer a faciliter ces changementsSo far, agricultural development has been the priority of the government of mali. Mali created institutions for organizing rural areas with an integrated approach : these are called rural development operations (roo's), of which ohv. Since their inception, the roo's have used various initiatives and strategies to achieve their objectives, mainly food self-sufficiency (cereal production) et cash crop intensification (cotton and tabacco at ohv). Despite these commendable efforts, the goal is not achieved. Agriculture officials encourage the creation of village associations (av's) to facilitate the accomplishment of the objectives. Rural people hope that these village cooperation will be as useful as their traditional associations, kare, sere and ton. Improving this situation calls for, on the one hand, a thorough knowlegge of the traditional structures and the role of their actors, men and women ; and, on the other hand, a better training of farmers to carry out activities to be transfered to their av's : :management, agricultural extension, etc. Functional literacy may contribute to facilitating these changes

Full textAbstract:
Dans des pays comme le mali, la haute-volta et le niger, qui sont pour des raisons historiques, geographiques, forts depourvus, la necessite de desenclaver devient plus qu'une priorite, une obsession. Surtout quand on sait que ces pays dependent des transports pour assurer leurs acces au marche international, s'approvisionner et faire fonctionner leurs economies. On mesure des lors toute leur importance et leur impact. La rapide mise en place d'une politique de transports doit s'inscrire dans une politique globale de developpement qui doit modifier les structures socio-economiques dont la croissance a ete faussee, bloquee ou et extravertie. Faute de quoi, non seulement le developpement lui-meme risquerait d'etre etrangle, mais aussi des localites, des regions voire les pays tout entier demeureraient enclaves. Car les interactions des transports sont des plus nombreuses et des plus diverses et interviennent ca et la. C'est pourquoi, il nous a paru interessant de montrer comment de plaque tournante autrefois, les pays interieurs de l'afrique de l'ouest sont devenus des "espaces delaisses" pour les communications et comment le systeme de transport s'est degrade avec le niveau de developpement. L'amenagement du territoire doit preciser une nouvelle geographie economique de meme que la bonne organisation, le bon fonctionnement des transports doivent tendre vers un developpement harmonieux de l'economie propice a une integration sous-regionaleIn deprived countries such as mali, upper-volta (burkina-faso) and niger which are for historical and geographical reasons bearing poverty, it has become a necessity, more an obsession to open up. Il l is all the more essential when we know that, these countries heavily rely on transports for their access to the international market, their food supplies and the good running of their economies. Through this their importance and their impact can be measured. The quick settlement of a transportation policy should be integrated in a global policy of development which should modify the socio-economc structures of which the growth was wrong, blocked or extroverted. If not, not only development runs the risk to be hindered, but also other territories areas , and even the whole country will be made enclaves. Interactions of transportation are more and more numeros and more and more various to intervene here and there. This is why, we have foud it quite interesting to show how from as turning point in the past : the inland areas of west africa have become "abandoned areas"for communications and how the transportation system has become obsolete to create or to be transformed in another system which doesn't cope with the level of development. Planning should settle a new economic geography as well as the good organization and functionning of the transports should aim towards a balanced development of the economy in favour of a subregional integration

Kohandani, Tafreshi Marzieh. "Reconstruction 3D du segment antérieur oculaire par échographie haute fréquence." Thesis, Brest, 2014. http://www.theses.fr/2014BRES0003.
Full textAbstract:
Une des applications de l’échographie médicale est celle de l’ophtalmologie qui pose de nombreux problèmes spécifiques liés en partie à la faible dimension de l’oeil et à la précision importante que requièrent les mesures intraoculaires. En effet, avec le développement de la chirurgie réfractive qui regroupe ensemble des techniques capables de corriger les erreurs de réfraction et l’avènement des implants intraoculaires, le chirurgien ophtalmologiste est amené à surveiller la tolérance et les effets secondaires de ces implants sur les structures du segment antérieur. L’échographie à haute fréquence apporte la résolution suffisante pour cette tâche. Cependant, le développement de l’échographie 3D permet une extension des applications ophtalmologiques notamment pour le dimensionnement des implants en préopératoire. La modélisation 3D du segment antérieur permet d’étudier le comportement des implants et surtout de dessiner à terme un implant « sur mesure » pour le patient. C’est dans ce contexte que nous présentons une méthode originale de segmentation et de reconstruction 3D du segment antérieur par échographique haute fréquence en utilisant l’ajustement de modèles 3D. Nous utilisons un système échographique 3D de type main-libre, composé d’une sonde échographique haute fréquence, et d’un module de localisation actif comprenant une caméra et des marqueurs infrarouges. Ce système échographique 3D nous permet d’obtenir des images avec des informations de positionnement dans l’espace tridimensionnel associées. Nous avons ainsi pu mettre en place toute une chaîne d’acquisitions et de traitements des images échographiques. Nous créons, à partir d’images échographiques du segment antérieur oculaire, des modèles de référence 3D réalistes. Nous proposons ainsi une méthode d’ajustement de modèles 3D de référence sur des données 3D échographiques via l’utilisation de l’algorithme de recalage ICP. Nous avons également sélectionné et adapté différentes méthodes pour l’évaluation de l’approche de reconstruction proposée. Ces méthodes permettent de mettre en valeur la précision de ces reconstructionsOphthalmology is one of the clinical application fields of ultrasound imaging, for which numerous specific issues arise, related in part to the eye’s small anatomical dimensions combined with the high level of accuracy requirements associated with intraocular measurements. Indeed, since the development of refractive surgery including all the techniques dedicated to the correction of refractive errors, as well as the emergence of intraocular lens (IOL), ophthalmic surgeons have to monitor overall acceptance as well as secondary effects related to these implants on the structures of the anterior eye segment. High frequency ultrasound imaging provides the required spatial resolution for this task. However, the development of 3D ultrasound imaging allows for the development of new applications in ophthalmology, for instance pre-operative dimensioning of the lens. 3D modelling of the anterior eye segment therefore allows studying the IOL behaviour and may help designing future personalized IOL tailored for each patient. Within this context, we present an original 3D segmentation and reconstruction method based on 3D models registration, dedicated to the anterior eye segment acquired in high frequency ultrasound imaging. We used a 3D ultrasound free-hand acquisition system, composed of a high frequency ultrasound probe and a localization module based on a camera and infrared markers. This 3D ultrasound system provides images along with associated 3D spatial positioning information. We were therefore able to develop an entire ultrasound images acquisition and processing chain. This allowed us creating realistic reference 3D models from sequences of ultrasound images of the anterior eye segment. We thus propose a method based on the iterative closest point (ICP) algorithm for the registration of the 3D reference models to 3D ultrasound acquired data. We have also selected and adapted various methods for the evaluation of the proposed reconstruction process. These methods highlight the accuracy of the obtained reconstructions

Full textAbstract:
Les dynamiques des rapports de genre se construisent à travers une analyse globale depuis la mise en place des populations. Cette analyse permet de porter un regard nouveau sur les rapports de genre autour d'enjeux social, culturel et économique en Haute Guinée. De l'organisation sociale et politique des communautés rurales de base ressort la position sociale qu'occupe chaque catégorie sociale à divers niveaux d'échelles (village, clan, famille). Les inégalités liées au genre influencent les processus sociaux et économiques. Les rapports de genre s'organisent à travers les faits et pratiques qui montrent une différenciation sociale mais aussi une hiérarchisation en faveur des hommes et des aînés. L'organisation sociale codifie les pratiques des uns et des autres dans un système gérontocratique. Les asymétries du genre constituées de différences et d'inégalités se transforment parfois, en réponse à l'évolution de la société ainsi qu'à des changements de conditions socio-économiques. C'est dans ce cadre que beaucoup de femmes de la Haute Guinée ont pris des initiatives et s'inscrivent actuellement dans des logiques d'exploitation du néré, un produit de cueillette utilisé comme condiment, ce qui leur permet d'avoir plus d'autonomie et peuvent, de ce fait, accéder aux moyens de production. Elles adhèrent aux organisations collectives, se déplacent de plus en plus vers des horizons lointains, bousculant ainsi l'ancienne hiérarchie de pouvoir fondé sur le sexe et l'âge.

Full textAbstract:
Men who have sex with men (MSM) account for a majority of all men currently diagnosed with AIDS. MSM is also recognized as the largest risk category of all AIDS cases. Drug use has been shown to have a synergistic effect on the prevalence of HIV in the MSM population. The study aimed to examine the association between injection drug use, non-injection drug use, and non-drug use with sexual risk behaviors for HIV in men who have sex with men. Secondary, cross-sectional data procured from the National HIV Behavioral Surveillance System for the Atlanta Metropolitan Survey Area were used for the study. The study population was 960 participants. Using binary logistic regression analyses, the drug use categories were studied for unprotected intercourse, unprotected receptive anal intercourse and HIV status. Strong associations were seen independently for unprotected intercourse, unprotected receptive anal intercourse, and HIV status with injection and non injection drug use, but the association weakened for drug use categories when controlled for other independent factors. Taking into account current findings and findings from previous research, the importance of clinical significance over statistical significance was considered. Racial disparities were evident, in that, although the Black participants showed no increased odds for sexual risk factors or drug use, it had a higher odds for being HIV positive compared to Whites. Combining Viagra/Levitra with drugs was significantly associated with unprotected intercourse (AOR=1.9), and each individual drug showed a different degree of association with Viagra/Levitra. Further research is recommended to identify sub-populations at risk and appropriately allocate resources and channel programs and interventions.

The aim of the study is to examine whether the six students feel the strogest connection with the press where they were raised or where they currently live, why they choose to use the media platforms they do and what meaning the use of the media bare to the students. We have seen a lack of information concerning why young people choose to consume news online instead of in printed media. The study is focused on theories concerning what affects people in their choice of media platforms and channels. This report shows that geographic nature, the quality of the content and which political ideology the daily press is founded on does not affect the respondents choice of media. Our study shows that the most important factor for the respondents is that the platform is easily accesssible and flexible. We can also see that the dissapering of the printed newspaper is connected to generations and techonology.

The relationship between investment fund raising and performance are very common in the literature of Brazilian funds, and papers shown that investors make their investment decisions based on the recent performance of the funds, applying more in funds with good recent performance than funds that yield below the market average.This work is dedicated to, more than investigate the uptake ratio and performance of investment funds in Brazil, further study regarding the payback period longer considered by investors when choosing products to invest, that is, if you are already documented the literature that this behavior exists, we want to know: what is the exact performance period more analyzed by investors when choosing your funds? The results achieved through regression on panel with fixed time effect model is that the deadlines that have greater representation in the investor's choice are the windows from one month up to six months and from six months up to one year history, longer terms have the same positive relationship but fall considerably.
A relação entre captação e desempenho é muito estudada na literatura brasileira de fundos. Os artigos sobre o tema atestam que os investidores tomam suas decisões de investimentos baseados no desempenho recente dos fundos, aplicando mais em fundos com bom desempenho recente do que em fundos que rendem abaixo da média de mercado. Esse trabalho dedica-se a, mais do que investigar a relação entre captação e desempenho de fundos de investimentos no Brasil, aprofundar o estudo no tocante ao prazo de retorno mais considerado pelos investidores ao escolherem em qual fundo investir. O resultado alcançado através de nossas regressões em painel com efeito fixo de tempo é de que os prazos com maior representatividade na escolha do investidor são as janelas de um até seis meses e de seis meses até um ano de histórico. Prazos maiores têm a mesma relação positiva, mas caem consideravelmente.

Full textAbstract:
Cette thèse a pour objectif de comprendre les différents aspects de l'évolution des amas d’étoiles massives NGC3603 et R136 qui possèdent les étoiles les plus massives connues de l'univers local. L'analyse photométrique des noyaux de R136 et NGC3603 utilisant l’imagerie infrarouge de l’instrument SPHERE sur VLT et son système d’optique adaptative extrême de SPHERE, m’a permis de détecter pour la 1ière fois un grand nombre d’étoiles de faibles masse et luminosité au coeur de ces amas et pour la plupart au voisinage des étoiles les plus lumineuses et massives. La comparaison des données de SPHERE de NGC3603 à celles du HST montre l’absence de ségrégation de masse dans le noyau de cet amas. De plus la pente de la fonction de masse de cette région est la même que celle de la région suivante et similaire aux valeurs de la MF correspondant aux régions extérieures de l’amas connues jusqu’ici. L’amas R136 est partiellement résolu par SPHERE/IRDIS dans l’IR. La majorité de ses étoiles massives ont des compagnons visuels. En prenant compte des mesures spectroscopiques et photométriques et leurs erreurs sur l'extinction et l'âge des membres de l’amas, j’ai estimé une gamme de masse pour chaque étoile identifiée. La MF a été calculée pour différents âges ainsi que les erreurs sur les masses stellaires. J’ai simulé des séries d'images de R136 grâce au code Nbody6, et les ai comparées aux observations du HST/WFPC2. Ces simulations permettent de vérifier l'effet de la binarité initiale des étoiles de l’amas, la ségrégation de masse et l'évolution des étoiles sur l'évolution dynamique propre à R136This thesis aims at studying 2 massive clusters NGC3603 and R136, and the mechanisms that govern their physics, These clusters host the most massive stars known in the local universe so far and are important clues to understand the formation and fate of very massive star clusters. The manuscript outlines the photometric analysis of the core of R136 and NGC3603 on the basis of HST data in the visible and the VLT high dynamic imaging that I obtained in the infrared thanks to the SPHERE focal instrument operated since 2015 and its extreme Adaptive Optics, In an extensive photometric study of these data I discovered a significantly larger number of faint low-mass stars in the core of both these clusters compared to previous works. These stars are often detected in the vicinity of known massive bright objects. By comparing HST and SPHERE measures, NGC3603 does not show any signature of mass segregation in its core since the MF slope of the very core and the next radial bin are similarly flat and agree well with the MF found in previous works of the outer regions. On the other hand R136 is partially resolved using the SPHERE/IRDIS mode with most of the massive stars having visual companions. Considering the spectroscopic and photometric errors on the extinction and the age of cluster members, I estimate a mass range for each detected star. The MF is plotted at different ages with given errors on stellar masses. Finally I demonstrate that we need more resolution to go further on studying R136 which is 7-8 times further than NGC3603

Full textAbstract:
La diminution de l'oxygenation arterielle et tissulaire - l'hypoxemie - se rencontre chez l'homme dans des conditions de diminution de la disponibilite de l'oxygene dans le milieu ambiant (hypoxie d'altitude, cas des residents permanents d'altitudes ou des visiteurs d'altitude), ou dans des conditions de diminution de l'efficacite des echanges gazeux respiratoires chez des personnes residents au niveau de la mer, telles que les bronchites obstructives chroniques ou les syndromes d'hypoventilation et les episodes d'apnees du sommeil. Divers ajustements phenotypiques permettent d'ameliorer l'apport, le transport et l'utilisation de l'oxygene pour l'ensemble de l'organisme : parmi ceux-ci l'hyperventilation chronique et la polyglobulie d'altitude agissent de concert pour augmenter l'oxygenation tissulaire. Diverses hormones sont susceptibles de modifier l'amplitude des reponses physiologiques a l'hypoxie. Ainsi, les steroides sexuels et les corticosteroides ont une influence marquante sur la physiologie et la physiopathologie des habitants ou visiteurs d'altitude. Une tres forte predominance de sujets masculins est observes dans les cas d'hypoventilation associees aux apnees du sommeil. Cette disparite s'attenue apres la menopause, le taux d'incidence chez les femmes rejoint alors celui qui est observe chez les hommes. De meme une fraction importante des natifs de haute altitude des regions andines, des montagnes rocheuses ou des hauts plateaux himalayens developpent un syndrome de desadaptation a l'altitude (mal chronique des montagnes) caracterise par une erythrocytose pathologique. Les patients presentent des hematocrites et des concentrations plasmatiques d'hemoglobine menacant gravement leur sante. Ces troubles pathologiques apparaissent chez les hommes apres la puberte et chez les femmes preferentiellement apres la menopause. Des dysfonctionnements respiratoires sont associes a l'apparition du mal chronique des montagnes : en dehors des cas cliniques presentant des facteurs obstructifs ou lies a des conditions environnementales defavorables (expositions a des poussieres et scories, tabagisme), les patients atteints de mal chronique des montagnes presentent une hypoventilation alveolaire chronique et une baisse de la chemosensibilite arterielle peripherique. Parmi les facteurs determinants ces differentes reponses, les steroides ovariens (progesterone et strogene) sont des candidats de choix qui agissent comme stimulants ventilatoires a action centrale et peripherique, et sont efficaces pour lutter contre les symptomes du mal chronique des montagnes. Le mal aigu des montagnes est un symptome qui apparait dans les premieres heures lors d'une exposition rapide a l'altitude. Une faible reponse ventilatoire a l'hypoxie est un des facteurs de predisposition au mal aigu des montagnes. La dexamethasone est un glucocorticoide de synthese efficace pour limiter les symptomes du mal aigu des montagnes, son action pourrait dependre en partie de modifications de la chemosensibilite peripherique. Le but de cette these est de mettre en evidence les modifications de la reponse chemosensible suite a divers manipulations hormonales. Des approches fonctionnelles (reponse ventilatoire chemosensible), neurochimiques (systemes catecholaminergiques centraux et peripheriques) et moleculaires (expression de genes specifiques dans les structures du chemoreflexe) ont ete utilisees afin de determiner les sites et mecanismes d'action de ces hormones chez des animaux adultes et au cours de la croissance.

Full textAbstract:
Le Sahel, région semi-aride située au sud du désert du Sahara, est particulièrement sensible au changement climatique et est soumise à une forte variabilité inter-annuelle et décennale des précipitations. Au cours des dernières décennies, la région a été marquée par deux périodes de sécheresse intense dans les années 1972-1973 et 1983-1984, qui ont eu des conséquences dramatiques sur les ressources en eau et la végétation, provoquant l'érosion des sols, d'énormes pertes en bétail et des récoltes catastrophiques accentuant la paupérisation des populations rurales. Ces travaux de thèse contribuent à un effort d'identification et de quantification par télédétection des changements d'états de surface sur une grande région du Sahel malien, le Gourma qui s'étend sur près de 90 000 km² et couvre tout le gradient bioclimatique sahélien. L'étude s'appuie sur une importante base de données constituée au sol par des sites pastoraux et agricoles suivis dans le cadre de plusieurs programmes nationaux et internationaux. Trois sources de données de télédétection sont utilisées : 1) l'imagerie multi-spectrale à haute résolution spatiale Landsat, 2) l'imagerie couleur à très haute résolution spatiale observée en vision pseudo-stéréoscopique de Google Earth et 3) le produit NDVI du capteur MODIS à moyenne résolution spatiale mais à haute répétitivité temporelle. Les résultats présentés fournissent une caractérisation détaillée à l'échelle de la région du Gourma des types de surfaces sol-végétation, de l'occupation agricole des sols, du fonctionnement hydrique et aussi des productions végétales moyennes sur 14 années, herbacées et foliaires des ligneux. Pour quelques-unes de ces variables, et sur une partie de la région au moins, les résultats ont quantifié la dynamique historique de 1986 à 2011. Au niveau de la commune de Hombori, l'historique remonte jusqu'à 1955. Les résultats montrent clairement que la dynamique des mises en culture n'est pas responsable de la concentration du ruissellement observé dans le Gourma comme ailleurs au SahelThe Sahel is a semiarid region located south of the Sahara desert. The Sahel is particularly sensitive to climatic change and is subject to a high inter-annual and decadal rainfall variability. This region was marked by two periods of very severe droughts which occurred in 1983 - 1984 and 1972-1973 within a long dry period which began in 1970. This long drought deeply impacted water resources and vegetation, causing soil erosion, huge livestock losses and catastrophic harvests accentuating the impoverishment of the rural population. This study is an attempt to characterize and quantify changes in soils, vegetation and hydrology at the scale of the Gourma region (90 000 km²) located in Northern Mali from the last 55 years. Three types of remote sensing data have been used: 1) high spatial resolution Landsat images, 2) very high spatial resolution Geo-Eye images (Google-Earth) and 3) NDVI data measured by the moderate spatial resolution satellite (MODIS). The approach aims to characterize soil surface texture, local redistribution of rainwater by surface run off, surface hydrology and vegetation cover changes over the considered period. Temporal dynamics of vegetation and soils are pointed out. Particularly, this study shows the strong relationships between soil types, surface hydrology and vegetation dynamics at different spatial scales. Land cover changes are also characterized over the considered period

Previous issue date: 2011-02-17The soybean crop has an important economic partner in the country, because Brazil is a major producer of the grain in the world. Rio Grande do Sul is a state with a grain production characteristic, among them rice and soybeans, with approximately six million hectares of paddy soils, where only one fourth is occupied by rice cultivation, and the rest remain fallow and underutilized. However, we have sought alternatives to the cultivation of these areas, with crops that support the environmental conditions, making it the most profitable areas. The objective of this study was to evaluate the performance of three soybean cultivars, as well as the physiological quality in planossolo seed produced, submitted to five plant populations. The experiment was conducted at Embrapa Clima Temperado in 2008/09 and 2009/10 crop, using five populations (16, 28, 40, 52 and 64 plants per m²) and three cultivars (BRS PampaRR, BRS BRS 246RR and BRS 255RR) arranged in blocks with three and four replications in their respective crop. Significant responses for most variables when subjected to population changes, decreasing the value of these when they population increased. Moreover, with increasing population, variables such as number of nodes, pod and seeds per unit area had increased in value in the branches, while the main stem remained almost flat. This demonstrates first that the effect of number of branches directly influences yield components, and second, the ability to adjust components before different populations. Variables such as seeds per pod and thousand seed weight did not change or contributed little in yield, and the response varies with the population. There was a positive relationship in the yield on the main stem population growth, has branches in the relationship was negative, ranging in 2009/10 crop among cultivars. Overall, the yield in the 2008/09 crop did not change significantly, while in 2009/10 crop there was significant increase in yield with population increase. For the cultivars, most of the variables there was significant response to the 2008/09 crop on the main stem and to the 2009/10 crop on branches, especially in BRS PampaRR and BRS 246RR cultivars, on the other hand the BRS 255RR cultivar stands in the variable thousand seeds weight. The components of yield are directly related to the branches and thus reflected in yield. However, the partial yield (main stem and branches) was not significant difference among cultivars. Thus we can conclude that the environment influences in the yield, as population and cultivars, the component that contributes most in yield is the number of pods, and the components behave differently on the main stem and branches.
A cultura da soja possui um importante papel sócio econômico no país, pois o Brasil é um dos maiores produtores do grão no mundo. O Rio Grande do Sul é um estado com características de produção de grãos, dentre elas o arroz e a soja, possuindo aproximadamente seis milhões de hectares de solos de várzea, onde apenas um quarto é ocupado pelo cultivo do arroz, e o restante permanece em pousio e subutilizada. No entanto, tem-se buscado alternativas ao cultivo destas áreas, com culturas que suportem as condições do ambiente, tornando as áreas mais rentáveis. O objetivo deste trabalho foi avaliar o comportamento de três cultivares de soja, assim como a qualidade fisiológica de sementes produzidas em planossolo, submetida a cinco populações de plantas. O experimento foi desenvolvido na Embrapa Clima Temperado nas safras 2008/09 e 2009/10, utilizando-se cinco populações (16, 28, 40, 52 e 64 plantas por m2) e três cultivares (BRS PampaRR, BRS 246RR e BRS 255RR) dispostos em blocos ao acaso em três e quatro repetições, nas respectivas safras. Houve resposta significativa para a maioria das variáveis analisadas quando submetidas à variação na população, decrescendo o valor destes quando se aumentou a população. Por outro lado, com o aumento da população, variáveis como número de nós, legumes e sementes por unidade de área tiveram um acréscimo no valor nos ramos, enquanto na haste principal permaneceu decaindo. Isso mostra primeiramente que o efeito do número de ramos influencia diretamente os componentes do rendimento, e em segundo, a capacidade de ajuste dos componentes perante diferentes populações. Variáveis como sementes por legume e peso de mil sementes não variaram ou pouco contribuíram no rendimento, além de variarem a reposta com a população. Houve uma relação positiva no rendimento na haste principal com o aumento da população, já nos ramos a relação foi negativa, variando na safra 2009/10 entre as cultivares. No geral, o rendimento na safra 2008/09 não apresentou variação significativa enquanto na safra 2009/10 houve acréscimo significativo no rendimento com o aumento da população. Em relação as cultivares, na maioria das variáveis houve resposta significativa para a safra 2008/09 na haste principal e para a safra 2009/10 nos ramos, destacando-se as cultivares BRS PampaRR e BRS 246RR, por outro lado a cultivar BRS 255RR se destaca na variável peso de mil sementes. Os componentes do rendimento estão diretamente relacionados com os ramos e consequentemente refletindo no rendimento. No entanto, o rendimento parcial (haste principal e ramos) não obteve diferença significativa entre as cultivares. Assim pode-se concluir que o ambiente influencia no rendimento, assim como a população e as cultivares, o componente que mais contribui no rendimento é o número de legumes, e os componentes se comportam diferentemente na haste principal e nos ramos.

Full textAbstract:
La fraction fermentescible des ordures ménagères (FFOM) comprend des déchets facilement biodégradables (alimentaires), et des lentement biodégradables (lignocellulosiques). La digestion anaérobie (DA) est une biotechnologie dans laquelle la FFOM est décomposé dans biogaz (CH4 + CO2). En raison de la teneur élevée en CH4 (50-70%), le biogaz pouvant être utilisé comme source d'énergie. En outre, DA produit un digestat partiellement stabilisé, riche d'éléments nutritifs. La DA à haute teneur en solides est une stratégie pour l'amélioration de l'efficacité. Elle correspond à une opération avec une teneur en matières sèches (MS) ≥ 10%, qui permet de réduire la taille du réacteur et les coûts de fonctionnement. Toutefois, l'augmentation de la MS peut entraîner une instabilité biochimique, et même une défaillance par acidification, à cause de la forte charge organique et l'accumulation d'inhibiteurs. L'inhibiteur le plus notable est NH3. Par conséquent, un équilibre entre l'amélioration de l'économie et l'instabilité est requis pour le traitement de la FFOM par DA à haute teneur en solides. Cette thèse de doctorat porte sur les principaux mécanismes cinétiques bio-physiques-chimiques mis en jeu lors de la DA à haute teneur en solides, dans le but d’optimiser son application. Des expériences de laboratoire ont mis en œuvre pour élucider les principales forces et faiblesses de ce procédé. Simultanément, le développement d'un modèle spécifique à la DA à haute teneur en solides a permis de condenser les connaissances expérimentales sur les effets qui se produisent lors de l'augmentation de la teneur de la MS. Les expériences en réacteur batch ont nécessité un compromis entre la teneur initiale en MS, le rapport entre l'inoculum et le substrat (X/S), l'alcalinité et la teneur en azote, afin d'évaluer les effets de l'augmentation de la teneur initiale en MS sur le rendement en CH4, l’élimination de la MS et la conversion de la demande chimique en oxygène. En particulier, des ratios X/S bas ont conduit à l'acidification, tandis que l'accumulation de NH3 a conduit à une accumulation d’acides gras volatils (AGV). Dans des expériences en semi-continue, la DA à haute teneur en solides nécessitait de diminuer le débit de l’effluent pour contrer l'élimination de la masse. Cependant, la mono-digestion de la FFOM facilement biodégradable ne peut pas supporter MS ≥ 10% sans augmenter le risque de surcharge. La surcharge était associée à la forte biodégradabilité et à l'accumulation de NH3. Par conséquent, l'ajout de sciure de bois à FFOM a permis à des réacteurs semi-continus de fonctionner jusqu'à 30% de MS, en raison de la biodégradabilité et de la teneur d'azote plus faibles ce substrat. La principale nouveauté de cette thèse est le développement d'un modèle pour la DA à haute teneur en solides. Ce modèle permet de simuler la dynamique masse et de MS dans des digesteurs, contrairement aux modèles sur des simulations de MS < 10%. Ce modèle prend également en compte l’effet de la concentration en MS sur les espèces solubles. Un module bio-physico-chimique « non idéal », modifiant les constantes d’équilibre acide-base, a été couplé ensuite au modèle. Il est à noter que la DA à haute teneur en solides est souvent caractérisée par une force ionique élevée (I ≥ 0,2 M), affectant le pH, la concentration en NH3 et le transfert de CO2 liquide-gaz. L'étalonnage du modèle a montré que la DA à haute teneur en solides requis plusieurs jeux de données expérimentaux pour contourner la « non-identifiabilité » des paramètres. La DA à haute teneur en solides pouvait fonctionner à une I allant jusqu'à 0,9 M et NH3 allant jusqu'à 2,3 g N/L, à des teneurs en MS élevées (25-30%). En outre, l'étalonnage a suggéré que l'utilisation d'une inhibition non-compétitive de NH3 devrait être testée plus avant. Il a également été recommandé de mettre au point d'autres développements du modèle. Ces résultats pourraient aider à l'optimisation de la DA à haute teneur en solidesThe organic fraction of municipal solid waste (OFMSW) includes readily biodegradable wastes such as food waste, and slowly biodegradable wastes such as lignocellulosic materials. Anaerobic digestion (AD) is a mature treatment biotechnology in which OFMSW is decomposed to a mixture of methane (CH4) and carbon dioxide (CO2), known as biogas. Due to the elevated CH4 content (50-70%), biogas can be used as a source of renewable energy. Moreover, AD yields a partially stabilized digestate, allowing the recycle of nutrients to agriculture. High-solids anaerobic digestion (HS-AD) is a well-suited strategy to enhance the overall AD efficiency for OFMSW treatment. HS-AD is operated at a total solid (TS) content ≥ 10%, permitting to reduce the reactor size and overall operational costs. Nonetheless, the TS increase can result into biochemical instability, and even reactor failure by acidification. Both the high organic load and the buildup of inhibitors can be responsible for the HS-AD instability. The most notable inhibitor in HS-AD of OFMSW is NH3. Therefore, a balance is often required between enhancing the HS-AD economy and the ‘undesired’ instability for OFMSW treatment. This PhD research investigated the main bio-physical-chemical mechanisms and kinetics in HS-AD of OFMSW, with the aim to optimize the industrial application and maximize the kinetic rates. Laboratory-scale batch and semi-continuous experiments highlighted the main strengths and weaknesses of HS-AD. Simultaneously, the development of a HS-AD model permitted to condense the experimental knowledge about the bio-physical-chemical effects occurring when increasing the TS content in HS-AD.HS-AD batch experiments required a tradeoff between the initial TS, the inoculum-to-substrate ratio (ISR), the alkalinity and the nitrogen content, to assess the effects of increasing the initial TS content upon the methane yield, TS removal and chemical oxygen demand conversion. Particularly, a low ISR led to acidification, whereas the NH3 buildup led to volatile fatty acid (VFA) accumulation, reducing the methane yield, whether or not co-digestion of OFMSW with beech sawdust was used.In semi-continuous experiments, HS-AD of OFMSW required a reduced effluent compared to the influent to counterbalance the organic mass removal associated to the biogas production. Nonetheless, mono-digestion of readily-biodegradable OFMSW could not sustain a TS ≥ 10% without exacerbating the risk of substrate overload. Overloading was associated to the high biodegradability and the NH3 buildup. Thus, adding sawdust to OFMSW permitted to operate the reactors up to 30% TS, due to the lower biodegradability and nitrogen content of lignocellulosic substrates. As the main novelty of this PhD research, a HS-AD model based on the Anaerobic Digestion Model No.1 (ADM1) was developed. This model simulates the reactor mass and TS in HS-AD, in contrast of models focusing on ‘wet’ AD simulations (TS < 10%). Moreover, the HS-AD model considers also the TS concentration effect on soluble species. A ‘non-ideal’ bio-physical-chemical module, modifying predominantly the acid-base equilibriums, was subsequently coupled to the HS-AD model. Noteworthy, HS-AD is often characterized by a high ionic strength (I ≥ 0.2 M), affecting the pH, NH3 concentration and CO2 liquid-gas transfer, as the most important triggers for HS-AD inhibition. The HS-AD model calibration required multiple experimental datasets to circumvent parameter non-identifiability. The model calibration showed that HS-AD of OFMSW might be operated at I up to 0.9 M and NH3 up to 2.3 g N/L, particularly at higher TS (25-30%). Moreover, the model calibration suggested that the non-competitive NH3 inhibition should be further tested. Further HS-AD model developments (e.g. precipitation) were also recommended. All these results might aid in the optimization of HS-AD for organic waste treatment, renewable energy and nutrient recovery

La restructuration des organisations complexes, comme celles des établissements de santé, est fortement influencée par les récents changements économiques, technologiques et réglementaires. Pour comprendre l'impact de ces mouvements de restructuration, il convient d’analyser les changements influençant fortement les différents niveaux hiérarchiques de l'organisation. Dans le contexte socio-économique français, les établissements de santé subissent actuellement de multiples transformations stratégiques et opérationnelles, qui obligent les professionnels à adapter leurs compétences et leurs capacités en conséquence. En effet, l'impact des innovations médicales, techniques et numériques conduit les structures à s’adapter au changement. Pour une mise en œuvre réussie, il est nécessaire que les différents acteurs interviennent simultanément. Ces derniers sont ensuite encouragés à se concentrer sur la mise à jour de la stratégie de l'organisation, l'amélioration du développement des ressources humaines et l'ajustement des modèles et processus nécessaires. Par conséquent, cette recherche s'appuie sur l'analyse de la performance organisationnelle dans une perspective d’alignement stratégique. Notre objectif est d'examiner les attentes managériales au sein d'un établissement de santé en pleine reconstruction. Les résultats de cette étude qualitative montrent la difficulté des managers dans la mise en place d’un parcours patient performant. Elle montre également que les transformations technologiques peuvent être utilisées pour assurer une très haute performance organisationnelle permettant aux acteurs de profiter de divers services intelligentsThe restructuring of complex organizations, such as those of health facilities, is strongly influenced by recent economic, technological and regulatory changes. To understand the impact of these restructuring movements, one must analyze the changes affecting the various hierarchical levels of the healthcare organization. Under the French socio-economic context, healthcare institutions are currently undergoing multiple strategic and operational transformations, which requires professionals to adapt their skills and capabilities accordingly. In fact, the impact of medical, technical and digital innovations is driving the concerned structures to emphasize value in their adaptations. For a successful implementation, it is necessary that concerned parties intervene. These latters are then encouraged to focus on updating the organization's strategy, improving human resources development and adjusting necessary patterns and processes. Therefore, this research relies on analyzing organizational performance from a strategic alignment perspective. We aim to examine the managerial expectations of a study sample of managers, professionals, and staff in a French hospital which are undergoing full reconstruction. The results of this qualitative study show the difficulty of managers to implement a successful patient pathway process. It also shows that technological transformations can be used to ensure a very high organizational performance allowing people to take advantage of various intelligent services

Full textAbstract:
In More Electric Aircraft, different power system activities are attributed to electrical means such as the start-up of the main engine. In this context, the study of the sensorless control of the Brushless Synchronous Starter Generator (BSSG) that is used to electrically start the main engine is revealed to be a very interesting issue. For long time, the elimination of the mechanical sensor was highly recommended for reliability, cost, weight, integration issues.Hence, this work aims to transpose the results obtained in the research area to an avionic testbench. It presents an adaptive sensorless technique to use when electrically starting the main engine of the aircraft. This is achieved by elaborating three different methods selected depending on the speed of the machine and based on the :- injection of a high frequency signal- use of the back-emf of the Permanent Magnet Generator (PMG)- use of the extended Kalman Filter EKFIn this work, it is shown that the …first method gives good position estimation results from standstill up to 8% of the rated speed. Then, the back-emfs of the PMG are used to detect the position of the BSSG when the speed exceeds the 8% of the rated speed. Good results are observed with this method at medium and high speed.For redundancy reasons, the EKF was also used in this work. Thus, the estimated position can be delivered via two different estimation algorithms in medium and high speed region.The implementation of the algorithm was achieved on an FPGA board since the latter can ensure a very tiny execution time. The fastness of the treatment ensures quasi-instantaneous position estimation and does not practically introduce any phase lag in the position estimationAujourd'hui, l'aviation est en train de vivre des évolutions technologiques concernant surtout l'attribution de différentes fonctionnalités aux équipements électriques et ceci au détriment d'équipements hydrauliques et mécaniques assurant les mêmes fonctionnalités.Dans le cadre de l'avion plus électrique, le démarrage électrique sans capteurs mécaniques de la turbine de l'avion préoccupe les avionneurs de nos jours. Les problèmes introduits par ce capteur ont été identifiés : problèmes de coût et de poids, problèmes de fiabilité et d'intégration.Ce travail présente alors une commande sans capteurs pour la machine synchrone à trois étages à utiliser durant le démarrage électrique de l'avion. Ceci est réalisé avec trois méthodes de détection de la position selon la vitesse de rotation, basées sur :- l'injection d'un signal à haute fréquence- l'utilisation d'un filtre de Kalman étendu FKE- les fém. du PMG (Permanent Magnet Generator) La première méthode donne de bons résultats d'estimation depuis l'arrêt jusqu'à 8% de la vitesse nominale de la machine. Au-delà de cette vitesse, es valeurs des fém. du PMG deviennent assez élevées pour être utilisées dans l'estimation de la position. De bons résultats sont obtenus à moyenne et haute vitesse.Pour des questions de redondance, le FKE est aussi utilisé. Ainsi, la position estimée peut être fournie par l'un des deux algorithmes à moyenne et haute vitesse.L'implémentation de ces algorithmes est réalisée via une carte FPGA étant donné que celui-ci garantit un temps d'exécution. La rapidité de traitement garantit une estimation de la position quasi-instantanée et donc n'introduit pratiquement pas des retards dans l'estimation

Full textAbstract:
Depuis la seconde moitié du XXe siècle, l’adoption internationale a connu un essor considérable. Institution multiple, s’inscrivant dans une perspective pluridisciplinaire, elle se caractérise essentiellement par deux éléments déterminants : la diversité et la juridicité. Elle revêt également une grande complexité, puisqu’elle touche à l’essence même de la famille, dans un contexte marqué par la recherche d’équilibre entre les différents droits étatiques. L’examen des notions intriquées d’intérêt supérieur de l’enfant et d’identité, ainsi que l’étude des rouages du mécanisme de la coopération interétatique consacré par la Convention de La Haye du 29 mai 1993, permettent, au-delà des spécificités précitées, d’analyser les fondements de l’adoption internationale. Cette analyse, menée à travers un regard comparatiste entre droit français et droit tunisien, droits que tout semble opposer, permet de dresser un aperçu général de l’organisation de l’adoption internationale, de la phase préalable, sous l’égide des autorités administratives, au prononcé de l’adoption internationale. Outre le choix du juge compétent, les problématiques relatives à l’organisation de la phase administrative, ainsi que celles inhérentes à la désignation de la loi applicable, imposent une étude approfondie des droits tunisien et français, et surtout un examen minutieux de la pratique jurisprudentielle dans les deux paysSince the second half of the 20th century, international adoption has become increasingly important. A Multifaceted institution, from a multidisciplinary perspective, its essential features are two decisive factors: diversity and juridical status. It is also a highly complex issue since it goes to the very core of the family, in a context characterized by the search for a balance between the various state laws. The review of the interlinked notions of the best interest of the child and of identity, as well as the study of the key components of intergovernmental cooperation enshrined in the Hague Convention of 29 May 1993, will enable us to analyze the cornerstones of international adoption beyond the aforementioned specifics. This analysis conducted through comparison between French and Tunisian law, laws that seem to be in opposition, gives an opportunity to produce an overview of the organization of international adoption from the preliminary phase under the auspices of administrative authorities, until when the international adoption is decided. In addition to the choice of the competent judge, all issues concerning the administrative stage, as well as those resulting from the designation of the applicable legislation, require a comprehensive study of Tunisian and French legislation, in particular a thorough examination of solutions which are usually sought before the courts in both countries

Full textAbstract:
Section 14 of the Constitution provides for the right to privacy, which includes the right not to
have the privacy of communications infringed. The right is also protected at common law - a
breach of a person's privacy constitutes an iniura. E-mail communications are therefore
protected by both, the common law and the Constitution.
The question that this work seeks to answer is, whether the Government has the right to intercept
and/or monitor private e-mail communications.
The right to privacy is not absolute, case law and legislation show that this right can be limited.
At common law, a valid defence will negate the unlawfulness of the invasion. In terms of the
Constitution, the right to privacy can only be limited in accordance with the limitation clause section
36. For each case, courts will have to balance, the government's interest in combating
crime and that of the citizen to the privacy of their e-mail communications.
In seeking to answer the question, this work considers the protection afforded by the common
law and the Constitution. It also considers statutes which limit the right to privacy, including
whether these statutes are applicable to e-mail communications and if they are, whether they
constitute a justifiable limitation of the right, for example: the Regulation of Interception of
Communications and Provision of Communication-Related Information Act and the Criminal
Procedure Act - which was enacted when the 'cyber-world' was non-existent. All statutes,
applicable to e-mail communications, provide for some form of requirements or guidelines
before communications can be intercepted or/ and monitored.
The right to privacy is also protected in foreign jurisdictions and is not absolute. There is
protection only against unreasonable invasions of privacy.
In conclusion, both statutory law and common law permit the government, within limitations, to
intercept or/ and monitor private e-mail communications. Where there are guidelines, regulating this power, the circumstance under which and when it can be exercised. This will amount to a
reasonable and justifiable limitation and therefore the right will not be violated.Thesis (LL.M.)-University of Natal, Durban, 2003.

In Taiwan, the establishment of shopping malls can be regarded as a kind of innovative consumer service, which affects the consumption patterns of retail business as a whole. The location of the shopping mall is a key factor in the business’ understanding and analysis of its consumers’ characteristics and behaviors. Therefore, the purpose of this study is intended to probe into the impact of the shopping mall location and consumer life style has on consumer behavior. Also, the results can serve as references to the shopping mall proprietor in their planning and setting marketing strategies and management system. The questionnarive survey method was used to collect the consumer behavior, life style and demographic data of consumers at suburban shopping malls （include TAIMALL and Metro Walk）and urban shopping malls （include Core Pacific City and Breeze Center）. The resulting data were analyzed by using factor analysis, cluster analysis to determine the consumer life styles, then the hypotheses of this study are tested by using chi-square. The research findings indicated that there is a significant difference among consumers’ consumption motivation, consumption category, transportation, time for transportation, consumption path and attractions of the shopping mall at different locations. The location, building structure, tenant category and the market position of different shopping malls careated different consumer behavior. Consumers of different life styles showed great difference in their needs of consumption category and transportation. If the shopping mall proprietor can boost their sales by pinpointing at the different life style of their consumers when choosing appropeiate category of product and offering convenient transportation service to match their needs. There are significant differences noted based on gender, age, education level, occupation, marrial status, transportation methods and residence of the consumers on their consumer behaviors, which showed that an individual’s socaial and cultural characteristics are reflected on how he/she shops.

As Taiwan being one of the top ten markets for Hollywood’s movies, it deserves much more attention from the researchers. The most important factor in the above framework is the success of the marketing and packaging strategies, which can be further divided into two elements, the marketing communication and non-marketing communication. In order to promote a movie, advertisements, public relations, and other marketing activities are needed. The key is to stick to the principal marketing goal. If the target is clear, the whole marketing strategies will go with the guideline and complete it. With an approach of qualitative research methods, this case study is based on data analysis, focus group interviews to collect the first-hand data and analyze with the second-hand literatures. Aside from the study, the researcher also interviewed numerous professionals in fields such as the production, processing, projection and distribution in Taiwan’s film industry in order to obtained more legitimate information.

This paper explores the effects of environment, organizational structure and task uncertainty have on MAIS in terms of Contingency Theory. Environmental elements can be divided into environmental uncertainty and the extent of implementing Balance Score Card. Organizational structure can be evaluated by decentralization and formalization. Task uncertainty stands for task difficulty and task validity. Lastly, the effectiveness of MAIS can be measured by users’ satisfaction and managerial performance. Data were collected from 2000 executives in Financial & Accounting Department in public offering companies in Taiwan. Valid samples amount to 294 in total. The research tests all hypotheses by using SEM and T-test. Empirical results show as follows: 1. Environmental factors have significant relationship to organizational structure. With higher environmental uncertainty and implementation of Balance Score Card, organizational structure tends to be organic. 2. Environmental factors have significant relationship to the performance of MAIS. With higher uncertainty in environment, implementing Balance Score Card has better performance on MAIS. 3. Environmental factors have significant relationship to task uncertainty. The higher uncertainty environment has, the more uncertainty task will have. 4. Higher task uncertainty has significant relationship to organizational structure. The higher task uncertainty has, the organizational structure tends to be more organic. 5. Implementing Balance Score Card has significant difference on the performance of MAIS. Implementing Balance Score Card will enhance the performance of MAIS in companies. 6. Whether a company implements Balance Score Card or not has significant difference on MAIS users’ satisfaction. After implementing Balance Score Card, MAIS users’ satisfaction will enhance.

Relação, Perdão e Reconciliação. Três conceitos que envolvem uma “mixórdia de
temáticas” e que implicam necessariamente um antes, um durante e um depois. Antes do
perdão, vem a relação, no sentido de uma urgente necessidade do ser humano em construir laços
consigo mesmo, com os outros e com Deus. Mas, porque o ser humano está longe de ser
perfeito, o mal surpreende a vida, invade o seu espaço interior, deixa-o na inquietude de uma
incompreensão instalada. E entre o mal que o ser humano pratica e o mal que o ser humano
sofre, surge o perdão, como um abraço impensável, um sinal de esperança num futuro diferente,
uma reinvenção de uma vida.
É deste pressuposto que se pode falar de reconciliação, como o depois do perdão, como
o resultado de uma decisão unilateral de amor, como premissa fundamental àquilo que todo o
ser humano deve ser: “imagem e semelhança de Deus”.Relationship, Forgiveness and Reconciliation. Three concepts which involve a kind of “melting pot” of ideas and which necessarily imply a before, a throughout and a after the events. Before the forgiveness comes the relationship, in the meaning of an urgent necessity of the human being in building bonds with himself, with the others and with God. However, as the human being is far from being perfect and faultless, the evil surprises life, invades its inner space and leaves the person in great concern with the feeling of misunderstood. And among the evil that is done to others and the one that is experienced comes the forgiveness, like an unthinkable hug, a sign of hope for a different future, a reinvention of life. It’s starting with this assumption that we can approach reconciliation, it’s what follows the forgiveness like the result of a unilateral decision of love, like fundamental principles of what a human being should be: “God image and likeness”.

Packaging is an important element responsible for brand growth and one of the main rea-sons for producers to gain competitive advantages through technological innovation. In this re-gard, the aim of this work is to design a fully autonomous electronic system for a smart bottle packaging, being integrated in a European project named ROLL-OUT. The desired application for the smart bottle is to act as a fill-level sensor system in order to determine the liquid content level that exists inside an opaque bottle, so the consumer can exactly know the remaining quantity of the product inside.
An in-house amorphous indium–gallium–zinc oxide thin-film transistor (a-IGZO TFT) model, previously developed, was used for circuit designing purposes. This model was based in an artificial neural network (ANN) equivalent circuit approach.
Taking into account that only n-type oxide TFTs were used, plenty of electronic building-blocks have been designed: clock generator, non-overlapping phase generator, a capacitance-to-voltage converter and a comparator. As it was demonstrated by electrical simulations, it has been achieved good functionality for each block, having a final system with a power dissipation of 2.3 mW (VDD=10 V) not considering the clock generator. Four printed circuit boards (PCBs) have been also designed in order to help in the testing phase.
Mask layouts were already designed and are currently in fabrication, foreseeing a suc-cessful circuit fabrication, and a major step towards the design and integration of complex trans-ducer systems using oxide TFTs technology.

Os Corpos de Bombeiros (CB) contam com uma rede de quartéis implantada em todo o território nacional, atualmente organizada por um modelo baseado nos limites territoriais das NUTS (Nomenclatura das Unidades Territoriais para Fins Estatísticos). Será, portanto, possível rentabilizar a rede de CB no patamar sub-regional, através da implementação de critérios de desempenho dos CB, entre eles, a população abrangida dentro dos tempos de resposta convencionados.
O objetivo deste trabalho é propor uma reorganização operacional da rede de quartéis já implantada nas Sub-Regiões da Lezíria do Tejo e Médio Tejo, tendo como base um modelo da Rede Principal dos Serviços Operacionais dos Corpos de Bombeiros em Portugal Continental. Para tal, definiram-se critérios com vista à constituição de Agrupamentos de CB, que partilhando entre si áreas de atuação, permite priorizar o despacho de meios baseado no tempo de resposta dentro dos limites dos Agrupamentos. A aplicação dos critérios contemplando a rede viária existente e a distribuição da população residente, permitiu, recorrendo ao software QGIS®, aferir as zonas com necessidade de reforço da rede de quartéis.
Aplicado o modelo à área de estudo, verificou-se um aumento de 18,4% (1.401 km2) de área e de 6,1% da população (30.524 habitantes) abrangidas dentro dos tempos de referência (10 e 20 minutos). Para garantir a atividade operacional nos 24 municípios abrangidos, a rede de CB contaria 24 quartéis sede e 22 postos avançados (reforço da atual rede com 8), guarnecidos no mínimo por um efetivo total de 1.897 bombeiros profissionais.
O facto da rede de quartéis já se encontrar implantada no território alvo de estudo e apenas necessitar de reforços pontuais, deveria ser atualmente um fator desencadeador de interesse na sua rentabilização por parte das várias entidades envolvidas.Fire Departments (CB) have a network of barracks deployed throughout the national territory, currently organized by a model based on the territorial limits of the NUTS (Nomenclature of Territorial Units for Statistical Purposes). Therefore, it will be possible to improve the fire department network at the sub-regional level, through the implementation of fire departments performance criteria, including the population coverage within the settled response times. The objective of this work is to propose an operational reorganization of the barracks network already implemented in the Sub-Regions of Lezíria do Tejo and Médio Tejo, based on a model of the Main Network of Operational Services for Fire Brigades in Mainland Portugal. To this end, criteria were defined with a view to the constitution of CB Groups, which sharing areas of activity among themselves, allows prioritizing the dispatch of means based on the response time within the limits of the Groups. The application of the criteria covering the existing road network and the distribution of the resident population, allowed, using the QGIS® software, to assess the areas in need of reinforcement of the barracks network. Applying the model to the Lezíria do Tejo and Médio Tejo sub-regions, there was an increase of 18,4% (1.401 km2) in area and 6,1% of the population (30.524 inhabitants) covered within the reference times (10 and 20 minutes). In order to guarantee operational activity in the 24 municipalities covered, the fire departments network would consist of a total of 24 headquarters and 22 outposts with a minimum of 1.897 professional firefighters. The fact that the barracks network is already implanted in the study target territory and only needs occasional reinforcements, should be a triggering factor of interest in its profitability by the various entities involved.
