Ps. -Apulée, "Herbier", introduction, traduction et commentaire / Translation of the "Herbarius" of Pseudo-Apuleius with notes and commentaryPradel-Baquerre, Mylène 13 December 2013 (has links)
Mon travail a consisté essentiellement à proposer une traduction moderne et scientifique de l’herbier du Ps.-Apulée, un texte du IVe siècle qui contient des recettes médicales associées à diverses plantes médicinales. Cet ouvrage a connu un grand succès au Moyen Âge et il en existe de nombreux manuscrits. Néanmoins, il a longtemps été méprisé et considéré comme une simple compilation d’ouvrages grecs. L’édition commentée la plus récente est celle d’Ackermann en 1788 et il n’y a pas de traduction française qui tienne compte l’édition d’E. Howald et H. Sigerist en 1927 et des progrès accomplis depuis dans la connaissance de ce texte. Nous avons donc essayé de traduire le texte de l’Herbier édité par ces deux savants tout en expliquant, critiquant et parfois contestant certains de leurs choix. Nous avons aussi cherché dans l’introduction et dans les notes à situer l’oeuvre dans la tradition médicale en travaillant à la fois sur les sources de l’oeuvre et sur sa postérité et nous avons joint à la traduction en annexes un certain nombre de nos outils de travail. Nous espérons que ce travail permettra de mieux comprendre ce que représentaient les plantes médicinales, « les simples », dans l’Antiquité tardive. / The primary objective of my research was to offer a modern and technical translation of the Herbarius of Pseudo-Apuleius. This document dates back to the 4th century and contains medical prescriptions associated with plants. During the Middle Age, the book was quite successful as numerous copies are available. For a long time, however, it was despised and considered as a simple compilation of Greek works. The most recent edition with commentaries is from Ackermann in 1788 and there is unfortunately no sufficient French translation to fully benefit from the 1927 commentaries of E. Howald and H. Sigerist and from more recents studies on this text. We have therefore attempted to translate the text edited by these two experts and have tried to explain as well as critique and at times dispute their choices. In the Introduction and the notes section, we have been mindful to respect the text’s medical tradition, researching its original sources and its posterity. We hope this research will help better understand the role and importance of medicinal plants, also known as “the simple ones”, in the late antiquity.

Flux or Fixed. Tax Reforms, Informal Economy and Foreign Investment in New EU Member States.Duman, Anil January 2010 (has links) (PDF)
The paper tries to analyze the tax reforms in new EU member states, and to understand how these developments came into existence. Despite several commonalities we argue that across country variation is very much present, especially in the areas of degree of dependence on indirect taxes as well as the share of each component in total tax revenue. Our preliminary evidence indicates that there are three identifiable groupings; Hungary, Slovenia and Czech Republic as the first, Poland and Slovakia as the second, and the rest of the countries as the third. From the clusters we claim that these differences reflect the underlying the structural characteristics of the economies, particularly the scope of the informal economy and the intensity of competition to attract foreign capital. The paper contributes to the literature in a number of ways. First, it gives a comprehensive overview of reforms and possible explanatory factors. Second, it attempts to categorize the transition countries according to the features of the tax systems adopted. Finally, it establishes a linkage between the informal sector, capital from external sources and why particular modifications were implemented.

The Role of Tax Treaties in Facilitating Development and Protecting the Tax BaseLang, Michael, Owens, Jeffrey January 2014 (has links) (PDF)
The amount of taxes paid by multinational enterprises (MNEs) in host and home
countries continues to make headline news. Corporate tax regimes, particularly those in
many OECD countries, have never been more complex and the competition to attract and
retain foreign direct investment (FDI) has perhaps never been so great. All of these
political, legal, economic and competitive realities face countries at a time when they
need additional budget revenues.
At the June 2012 G-20 Summit in Los Cabos, leaders identified base erosion and profit
shifting as key fiscal issue to be addressed. Many are expecting this to translate into a
new approach to applying existing international tax standards, an increased pressure to
eliminate "corporate tax breaks", enact tougher anti-abuse provisions, and less tolerance
of aggressive tax planning.
There has been an increased critical focus on transfer pricing, corporate restructuring and
double tax treaties. Some have suggested that double tax treaties are eroding the
domestic tax bases of developing countries, while others conclude that double tax
treaties promote development and FDI and thereby expand the tax base. Dividing up a
"revenue pie" has never been easy and the implementation of international tax rules to
transparently and predictably allocate revenue to avoid double taxation and double non
taxation has never been more adversarial between taxpayers and tax authorities and
between tax jurisdictions.
It was for these reasons that the Global Tax Policy Center of the Institute for Austrian
and International Tax Law (Vienna University of Economics and Business) and the
International Tax and Investment Center (ITIC) decided to undertake this study. The
objective of our study was to look at the development impact of double taxation treaties
and, more broadly, how tax policy can help generate economic growth and
prosperity. Legally domestic tax laws are normally subordinate to international double
taxation treaties, but in reality a double tax treaty only serves a country as well as its
domestic tax regime.
We've concluded that the problems affecting developing countries lie not with double tax
treaties but rather in weak domestic tax legislation. Our study reviews empirical data
from 20 developing countries, including LDCs, middle-to-high income developing
countries, resource-rich countries, and BRIICS[1] countries.
We hope that the empirical analysis and the conclusions that can be drawn from it can
help guide policymakers to refocus their policy objectives to boost capital formation,
expanding exports, and protect their domestic tax bases. We believe that a country with
strong domestic tax legislation can advance their pursuit of the Millennium Development
Goals by affectively utilizing double tax treaties and the related international tax rules to
more transparently share and grow their tax base. (authors' abstract) / Series: WU International Taxation Research Paper Series

How does globalization affect the tax burden on labour income, capital income and consumption in different welfare regimes. The case of Western and Eastern EU Member States.Onaran, Özlem, Bösch, Valerie, Leibrecht, Markus January 2010 (has links) (PDF)
This paper analyzes the effects of globalization on implicit tax rates (ITRs) on labour income, capital income, and consumption in the EU15 and Central and Eastern European New Member States (CEE NMS). We find a positive effect of globalization on the ITR on labour income in the EU15, but no effect on the ITR on capital income, and a negative effect on ITR on consumption. There is a significant negative effect on the ITR on capital income in the social-democratic and southern welfare regimes, a marginally significant negative effect in the liberal regime; a negative effect on the ITR on consumption in the social-democratic, conservative, and liberal regimes; and a positive effect on the ITR on labour income in all welfare regimes. In the CEE NMS there is no effect of globalization on any ITRs. (author's abstract) / Series: Discussion Papers SFB International Tax Coordination

applications in biomedicine, optical and electronic fields. Many studies have been carried out
in order to produce polymeric particles in nano scale. The main reason for this is the higher
ratio of surface area per volume, which results in specific characteristics. Such considerations
have driven researchers to develop techniques to obtain polymeric nanoparticles with
properties that allow application in different areas. In the present work is proposed a
polymerization process by atomization applied to miniemulsion and suspension systems for
formation of submicron particles of poly(methyl methacrylate) (PMMA) and polystyrene
(PS), in the form of homopolymer and copolymer. In this technique, a simple atomizer device
is used as an alternative method to generate the monomer droplets before the dispersion in
reaction medium. Reactions using the proposed technique were carried out and the particles of
PMMA and PS obtained by suspension or miniemulsion polymerizations were analyzed by
dynamic light scattering (DLS), scanning electron microscopy (SEM) and transmission
electron microscopy (TEM). It was observed through DLS analysis that polymeric particles
were obtained with average size between 40 and 1400 nm. Concerning the SEM and TEM
analysis, it was possible to observe that the particles generally reached sizes below 200 nm
and with well-defined and spherical morphological characteristics. Such results were obtained
even in the polymerizations using suspension formulations, which is not common of getting
with conventional techniques. On the other hand, the proposed technique in this study has
demonstrated difficulty in reaching high solid contents, being the maximum value obtained of
130 g/L. Such limitation is associated with the drag of the monomer droplets during
atomization, being this effect more particularly pronounced when the monomer is more
volatile. For this reason, different configurations of the polymerization system were tested for
the purpose of improvement of results. Besides to demonstrate that is able to obtain polymeric
nanoparticles, the technique proposed in this work looks promising in obtaining carrier
particles, being, therefore, an interesting alternative by the facility of adaptation to large scale,
differently of the conventional methods of polymeric nanoparticles production.

FlorilegiumVogel, Molly January 2016 (has links)
This thesis is composed of two parts, encompassed in a third: a poetry collection; a critical dissertation; and an artist’s book. The thesis as a whole is entitled Florilegium. This title, from the Latin flos, or ‘flower’, and legere, ‘to gather’, refers to the medieval system of collecting extracts from various authors to form a larger body of work. It is also applicable to flower-treatises, dedicated to their ornamental nature rather than medicinal or scientific. The critical dissertation comes in the form of a glossary. It intends to show that the flower plays an essential role in linking Modernist poetics with that of its Romantic predecessors and beyond. In isolated and ‘illuminated’ examples from Aristotle to Zukofsky, it examines the lineage of botanical poetry, in the light of its unique linguistic makeup: a vernacularized scientific lexicon established in the Latin of Carl Linnaeus. While the critical component of the thesis is an interrogation of botanical language, the poetry collection is its living representation. To enhance the living nature of the text, I have designed and printed an artist’s book, which also acts as an herbarium for floral specimens collected and pressed over the duration of my degree. The design of the book is in keeping with traditional florilegia, incorporating historic binding techniques, typography, paper, and size.

Time series analysis of SAR images using persistent scatterer (PS), small baseline (SB) and merged approaches in regions with small surface deformation / Analyse des séries temporelles des images SAR par le biais des méthodes « persistant scatterer » (PS), « smal baseline » (SB) et l’approche de fusion dans les régions à petite déformation des surfaceBouraoui, Seyfallah 02 July 2013 (has links)
Cette thèse porte sur l’étude de la déformation de surface (petite et grande déformation) pouvant être détectée en utilisant la méthode de l’interférométrie "InSAR " pour le traitement des images SAR (Synthetic Aperture Radar, bande C : λÉ = 5.6 cm) et signal associé à synthèse d'ouverture. Les nouveaux développements des techniques de traitement InSAR permettent le suivi de la déformation en surface avec une précision de l'ordre millimétrique. Les traitements dites conventionnels de l'InSAR utilisent une paire d'images SAR ("Maitre" et "Esclave") afin de mesurer la différence de phase entre les deux prises de la même scène d'image à des moments différents. Les incertitudes dans les mesures obtenus à partir du traitement conventionnel de l'InSAR sont nombreuses : la décorrelation dans le signal en raison du délai du à l'atmosphère, la contribution topographique et les positions orbitales sont les handicaps majeurs de cette technique. En 2001, Ferretti et al. ont introduit une nouvelle méthode appelée Permanent Scatterer (PS-InSAR) également connue sous le nom de Persistent Scatterer. Pour cette méthode, nous utilisons une série d'images, dont une dite esclave pour construire des interférogrammes avec la même image dite « Maître ». Cette méthode permet d'améliorer le signal de visé (LOS) en terme de correlation pour chaque pixel (PS) en utilisant les meilleurs réflecteurs donnant une corrélation maximale (à partir de l'amplitude et/ou la phase) dans le temps et dans l'espace. Un grand nombre d'algorithmes a été élaboré à cet effet en utilisant le même principe (des variantes) décrit auparavant. En 2002, Berardino et al. publient un nouveau algorithme développé pour le suivi de la déformation en surface en se basant sur les interférogrammes produits à partir des couples d’image SAR ayant une petite séparation spatial (SBAS) de la ligne de base.Dans cette thèse, les techniques InSAR sont appliquées pour différents cas d’étude allant de la petite déformation en surface telle que: 1) Un affaissement dans une zone de puits de pétrole, 2) des glissements de terrain dans une zone urbaine, et 3) la déformation lente à travers les zones de failles des zones sismiques. Afin d'étudier la petite déformation j'opte pour l’utilisation des deux algorithmes (PS et SBAS) dit de traitement multi-temporelle de l’InSAR incorporés dans le logiciel StaMPS (Hooper, 2008). Ainsi, j’ai pu calculer la méthode de combinaison ou hybride entre PS et SBAS et ce, pour toutes les études de cas présentées dans cette thèse. Par ailleurs, certains logiciels en libre accès sont utilisés tout au long de cette thèse tel que, Roi-pac (Rosen et al., 2004) pour aligner les images SAR ainsi que Doris (Kampes et al., 2003) pour calculer interférogrammes à partir de images SAR.[...] / This thesis aims at the study of small to large surface deformation that can be detected using the remote sensing interferometric synthetic aperture radar (InSAR) methods. The new developments of InSAR processing techniques allow the monitoring of surface deformation with millimeter surface change accuracy. Conventional InSAR use a pair of SAR images (“Master” and “Slave” images) in order to measure the phase difference between the two images taken at different times. The uncertainties in measurements using the conventional InSAR due to the atmospheric delay, the topographic changes and the orbital artifacts are the handicaps of this method. The idea of InSAR method is to measure the phase difference between tow SAR acquisitions. These measure refere to the ground movment according to the satellite position. In interferogram the red to blue colors refere to the pixel movement to or far from the satellite position in Line-Of-Sight (LOS) direction. In 2000’s, Radar spacecraft have seen a large number of launching mission, SAR quisitions and InSAR applicability have seen explosion in differents geophysical studies due to the important SAR datas and facility of data accessibity. This SAR-mining needs other type and generation of InSAR processing.In 2001, Ferretti and others introduce a new method called Permanent Scatterer InSAR (PS) that is based on the use of more than one Slave image in InSAR processing with the same Master image. This method allows enhancing the LOS signal for each pixel (PS) by using the best time and/or space-correlated signal (from amplitude and/or from phase) for each pixel over the acquisitions. A large number of algorithms were developed for this purpose using thesame principle (variantes). In 2002, Berardino et al developed new algorithm for monitoring surface deformation based on the combination of stack of InSAR results from SAR couples respecting small baseline (SB) distance. Nowadays, these two methods represent the existing time series (TS) analysis of SAR images approaches. In addition, StaMPS software introduced by Hooper and others, in 2008 is able to combine these two methods in order to take advantages from both of this TS approaches in term of best signal correlation and reducing the signal noise errors. In this thesis, the time series studies of surface changes associate to differents geophysical phenomena will have two interest: the first is to highlight the PS and SBAS results and discuss the fiability of obtained InSAR signal with comparation with the previous studies of the same geophysical case or observations in the field and in the second time, the combined method will also validate the results obtained separately with differents TS techniques. The validation of obtained signal is assured by these two steeps: Both of PS and SBAS methods should give relatively the same interferograms and LOSdisplacement signal (in term of sign and values), in addition these results will be compared with the previous studies results or with observations on the field.In this thesis, the InSAR techniques are applied to different case-studies of small surface deformation [...]

Uncertainty in Weighting Formulary Apportionment Factors and its Impact on After-Tax Income of Multinational GroupsOrtmann, Regina January 2015 (has links) (PDF)
Formulary apportionment is an intensively debated mechanism for allocating tax base within
multinational groups. Systems under which the formula is identical in all jurisdictions and systems
under which jurisdictions can determine the weights on the formula factors individually can be
observed. The latter systems produce uncertainty about the overall tax-liable share of the future group
tax base. Counter-intuitively, I identify scenarios under which increased uncertainty leads to higher
expected future group income. My results provide helpful insights for firms and policy makers
debating the specific design of a formulary apportionment system. (author's abstract) / Series: WU International Taxation Research Paper Series

Previous issue date: 2016-02-29 / This study analyzes the filling of the first person singular subject in Portuguese in the city of Feira de Santana. In order to achieve this research, we used two corpora denominated university level speakers and elementary school 1 speakers,a total of 24 surveys, twelve for each sample, which were divided into three age groups. The samples belong to the project called A L?ngua Portuguesa no Semi?rido Baiano, based on the N?cleo de Estudos da L?ngua PortuguesaUniversidade Estadual de Feira de Santana- Ba.This research aims to verify if the Portuguese spoken in Feira de Santana has shown a tendency to fill the subject. In order to achieve this goal we compare the two samples as well as dialogue with other researches. The analysis took as theoretical assumption the principles of Quantitative Sociolinguistics that through the statistical model correlates the variable under study withsocial and linguistic factors, providing a value (relative importance) for each one. The analysis of the results indicated a greater realization of the subject onthe Portuguese spoken by the most educated people; the study in apparent time showed that the elementary school I Portuguese is in the process of a possible change. / Neste estudo, analisa-se o preenchimento do sujeito de 1? ps. no portugu?s de Feira de Santana.
