Modern sediments and Pleistocene reefs from isolated carbonate platforms (Iles Eparses, SW Indian Ocean): A preliminary study

Isolated carbonate platforms occur throughout the geologic record, from Archean to present. Although the respective roles of tectonics, sediment supply and sea-level changes in the stratigraphical architecture of these systems are relatively well constrained, the details of the nature and controls on the variability of sedimentological patterns between and within individual geomorphologic units on platforms have been barely investigated. This study aims at describing and comparing geomorphological and sedimentological features of surficial sediments and fossil reefs from three isolated carbonate platforms located in the SW Indian Ocean (Glorieuses, Juan de Nova and Europa). These carbonate platforms are relatively small and lack continuous reef margins, which have developed only on windward sides. Field observations, petrographic characterization and grain-size analyses are used to illustrate the spatial patterns of sediment accumulation on these platforms. The internal parts of both Glorieuses and Juan de Nova platforms are blanketed by sand dunes with medium to coarse sands with numerous reef pinnacles. Skeletal components including coral, green algae, and benthic foraminifera fragments prevail in these sediments. Europa platform exhibits a similar skeletal assemblage dominated by coral fragments, with the absence of wave-driven sedimentary bodies. Fossil reefs from the Last interglacial (125,000 years BP) occur on the three platforms. At Glorieuses, a succession of drowned terraces detected on seismic lines is interpreted as reflecting the last deglacial sea-level rise initiated 20,000 years ago. These findings highlight the high potential of these platforms to study past sea-level changes and the related reef response, which remain poorly documented in the SW Indian Ocean.

Challenges for a shared European countryside of uncertain future. Towards a modern community based landscape perspective

This paper addresses current changes in the highly diverse European landscape, and the way these transitions are being treated in policy and landscape management in the fragmented, heterogeneous and dynamic context of today’s Europe. It appears that intersecting driving forces are increasing the complexity of European landscapes and causing polarising developments in agricultural land use, biodiversity conservation and cultural landscape management. On the one hand, multifunctional rural landscapes, especially in peri-urban regions, provide services and functions that serve the citizens in their demand for identity, support their sense of belonging and offer opportunities for recreation and involvement in practical landscape management. On the other hand, industrial agricultural production on increasingly large farms produces food, feed, fibre and energy to serve expanding international markets with rural live ability and accessibility as a minor issue. The intermediate areas of traditionally dominant small and family farms in Europe seem to be gradually declining in profitability. The paper discusses the potential of a governance approach that can cope with the requirement of optimising land-sharing conditions and community-based landscape development, while adapting to global market conditions.

Efficient split eld FDTD analysis of third-order nonlinear materials in two-dimensionally periodic media

In this work the split-field finite-difference time-domain method (SF-FDTD) has been extended for the analysis of two-dimensionally periodic structures with third-order nonlinear media. The accuracy of the method is verified by comparisons with the nonlinear Fourier Modal Method (FMM). Once the formalism has been validated, examples of one- and two-dimensional nonlinear gratings are analysed. Regarding the 2D case, the shifting in resonant waveguides is corroborated. Here, not only the scalar Kerr effect is considered, the tensorial nature of the third-order nonlinear susceptibility is also included. The consideration of nonlinear materials in this kind of devices permits to design tunable devices such as variable band filters. However, the third-order nonlinear susceptibility is usually small and high intensities are needed in order to trigger the nonlinear effect. Here, a one-dimensional CBG is analysed in both linear and nonlinear regime and the shifting of the resonance peaks in both TE and TM are achieved numerically. The application of a numerical method based on the finite- difference time-domain method permits to analyse this issue from the time domain, thus bistability curves are also computed by means of the numerical method. These curves show how the nonlinear effect modifies the properties of the structure as a function of variable input pump field. When taking the nonlinear behaviour into account, the estimation of the electric field components becomes more challenging. In this paper, we present a set of acceleration strategies based on parallel software and hardware solutions.

Les droits réels et personnels sur les titres détenus auprès d'un intermédiaire : analyse comparative en droit québécois interne et international privé

Les transactions sur les valeurs mobilières ainsi que leur mise en garantie se font bien au-delà des frontières nationales. Elles impliquent une multitude d’intervenants, tels que l’émetteur, un grand nombre d’intermédiaires disposés en structure pyramidale, un ou des investisseurs et, bien évidemment, les bénéficiaires desdites valeurs mobilières ou garanties. On peut aussi signaler l’existence de nombreux portefeuilles diversifiés contenant des titres émis par plusieurs émetteurs situés dans plusieurs états. Toute la difficulté d’une telle diversité d’acteurs, de composantes financières et juridiques, réside dans l’application de règles divergentes et souvent conflictuelles provenant de systèmes juridiques d’origines diverses (Common Law et civiliste). De nombreux juristes, de toutes nationalités confondues, ont pu constater ces dernières années que les règles de création, d’opposabilité et de réalisation des sûretés, ainsi que les règles de conflit de lois qui aident à déterminer la loi applicable à ces différentes questions, ne répondaient plus adéquatement aux exigences juridiques nationales dans un marché financier global, exponentiel et sans réelles frontières administratives. Afin de résoudre cette situation et accommoder le marché financier, de nombreux textes de loi ont été révisés et adaptés. Notre analyse du droit québécois est effectuée en fonction du droit américain et canadien, principales sources du législateur québécois, mais aussi du droit suisse qui est le plus proche de la tradition civiliste québécoise, le tout à la lueur de la 36e Convention de La Haye du 5 juillet 2006 sur la loi applicable à certains droits sur des titres détenus auprès d'un intermédiaire. Par exemple, les articles 8 et 9 du Uniform Commercial Code (UCC) américain ont proposé des solutions modernes et révolutionnaires qui s’éloignent considérablement des règles traditionnelles connues en matière de bien, de propriété, de sûreté et de conflits de lois. Plusieurs autres projets et instruments juridiques dédiés à ces sujets ont été adoptés, tels que : la Loi uniforme sur le transfert des valeurs mobilières (LUTVM) canadienne, qui a été intégrée au Québec par le biais de la Loi sur le transfert de valeurs mobilières et l’obtention de titres intermédiés, RLRQ, c.T-11.002 (LTVMQ) ; la 36e Convention de La Haye du 5 juillet 2006 sur la loi applicable à certains droits sur des titres détenus auprès d'un intermédiaire; la Loi fédérale sur le droit international privé (LDIP) suisse, ainsi que la Loi fédérale sur les titres intermédiés (LTI) suisse. L’analyse de ces textes de loi nous a permis de proposer une nouvelle version des règles de conflit de lois en matière de sûretés et de transfert des titres intermédiés en droit québécois. Cette étude devrait susciter une réflexion profonde du point de vue d’un juriste civiliste, sur l’efficacité des nouvelles règles québécoises de sûretés et de conflit de lois en matière de titres intermédiés, totalement inspirées des règles américaines de Common Law. Un choix qui semble totalement ignorer un pan du système juridique civiliste et sociétal.

Review of order fulfilment models for Catalogue Mass Customization

Mass Customization (MC) is not a mature business strategy and hence it is not clear that a single or small group of operational models are dominating. Companies tend to approach MC from either a mass production or a customization origin and this in itself gives reason to believe that several operational models will be observable. This paper reviews actual and theoretical fulfilment systems that enterprises could apply when offering a pre-engineered catalogue of customizable products and options. Issues considered are: How product flows are structured in relation to processes, inventories and decoupling point(s); - Characteristics of the OF process that inhibit or facilitate fulfilment; - The logic of how products are allocated to customers; - Customer factors that influence OF process design and operation. Diversity in the order fulfilment structures is expected and is found in the literature. The review has identified four structural forms that have been used in a Catalogue MC context: - fulfilment from stock; - fulfilment from a single fixed decoupling point; - fulfilment from one of several fixed decoupling points; - fulfilment from several locations, with floating decoupling points. From the review it is apparent that producers are being imaginative in coping with the demands of high variety, high volume, customization and short lead times. These demands have encouraged the relationship between product, process and customer to be re-examined. Not only has this strengthened interest in commonality and postponement, but, as is reported in the paper, has led to the re-engineering of the order fulfilment process to create models with multiple fixed decoupling points and the floating decoupling point system

Normative conflicts in international investment law: the case of environmental law

This dissertation investigates the relationship between investment and environmental obligations from the perspective of international investment law. In order to do so, the dissertation will consider how these obligations might enter into conflicts and what tools are available to investment tribunals to solve these normative conflicts. The dissertation analyses in order interpretative techniques, conflict resolution tools available in general international law, as expressed in the Vienna Convention on the Law of Treaties, and finally express clauses in international investment agreements. The dissertation includes the review of some relevant case law arising from investment agreements in investment treaty tribunals, to discover how in practice these conflict resolution tools are applied and to assess their effectiveness. This dissertation places itself squarely within the debate between the unity and the fragmentation of international law; therefore it tackles the issue of normative conflicts resolution in a dispute settlement environment with the view of gauging their value in maintaining the unity of international law and defuse the risk of fragmentation. The dissertation can only conclude that much work remains to be done, including by providing a more comprehensive taxonomy of possible interventions, both on the legal and political sphere.

Establishing continental sovereignty in Africa: risk and opportunity in financial integration - lessons for Africa from a legal perspective

This thesis identifies and defines the new African sovereignty. It establishes a modern sovereignty in Africa hatched from the changing nature of sovereignty in which countries come together at various levels or grades of partial surrender of national sovereignty in order to work closer together for their mutual advantage and benefit. To this end, the narrative zooms in on the central issues within the realms of money matters whereby a new model of monetary sovereignty and monetary solutions is designed in an attempt to ease the recurring tensions and challenges of modern national sovereignty in the continent of Africa. As such, this discussion will offer a historical journey through the constitution of sovereignty, to the birth of the nation state and international public law. It develops the theory of the changing nature of sovereignty within the modern state and opens new lines of inquiry for Africa. In this regard, it draws from juxtaposing and mixing elements of regional and global financial integration as well as retaining national financial sovereignty features to form this new design which I dub continental sovereignty. At its core, the thesis will deal with the legal aspects that stem from the co-mingling of legal systems of nation states and communities at the regional and global levels within the context of financial integration. The argument is that the rule of law remains sacrosanct in monetary management. Effective financial integration is the result of properly structured and managed legal frameworks with robust laws and institutions whether at a national, regional or global level. However, the thesis reveals that in order to avoid undermining the progress of Africa’s financial integration project, any solution for Africa must be immersed within a broader global solution where development issues are addressed and resolved and Africa can form a more central part in all relevant international discussion fora. The work will expound these issues by applying them within a regional and global context, with the state of affairs in Africa forming the nucleus. This application consequently presents the six key themes of the thesis which will be considered therein. They are: a.) regional advantage: which exploits the possibilities of deeper and further financial integration between smaller communal arrangements; b.) regional risk and exposure: the extent to which this deeper form of financial integration can spiral out of control if effected too quickly and too ambitiously; c.) global advantage: which considers the merits of global financial integration and the influence exerted by financial laws on the global financial architecture; d.) global risk and exposure: which considers the challenges of global financial integration especially within the background of the Global Financial Crisis 2007-2008; e.) African challenge: which considers the extent to which this analysis impacts the African economic and financial integration agenda; and f.) development challenge: which examines the extent to which global development issues impact the African solution (continental sovereignty) and the need for any solution for the continent to be roped into a broader global solution within which Africa can form an important part. Even though the thesis requests an optimistic undertone on the progress made so far, it unearths the African problem of multiple national sovereignty and multiple overlapping regional sovereignty constituted as the ‘spaghetti bowl’ dilemma. As such, the unique contribution to knowledge on financial integration in Africa can be echoed in these words: Africa‘s financial integration agenda has had little success in authenticating a systematic and dependable legal framework for monetary management. Efforts made have been incomplete, substandard, and not carefully followed through particularly reflected in the impuissant nature of the judicial enforcement mechanisms. Thus, the thesis argues that, any meaningful answer to the problems dogging the continent is inter alia deeply entrenched within a new form of cooperative monetary sovereignty. In other words, the thesis does not prescribe the creation of new laws; rather it advocates the effective enforcement of existing laws.

Translation – The fifth language skill? A comparison of the role of translation in Finnish lukio and the International Baccalaureate Diploma Programme

This study attempts to answer the question “Should translation be considered a fifth language skill?” by examining and comparing the use of translation as a language learning and assessment method in the national Finnish lukio curriculum and the curriculum of the International Baccalaureate Diploma Programme (IBDP). Furthermore, the students’ ability to translate and their opinions on the usefulness of translation in language learning will be examined. The students’ opinions were gathered through a questionnaire that was given to 156 students studying in either lukio or the IBDP in Turku and Rovaniemi. I present and compare the role of translation in selected language teaching and learning methods and approaches, and discuss the effectiveness of translation as a language learning method and an assessment method. The theoretical discussion provides the basis for examining the role of translation as a language learning method and an assessment method in the curricula and final examinations of both education programs. The analysis of the two curricula indicated that there is a significant difference in the use of translation, as translation is used as a language learning method and as an assessment method in lukio, but is not used in either form in the IB. The data obtained through the questionnaire indicated that there is a difference in the level of language competence between the lukio and IB students and suggested that the curriculum in which the student studies has some effect on his/her cognitive use of translation, ability to translate and opinions concerning the usefulness of translation in language learning. The results indicated that both groups of students used translation, along with their mother tongue, as a cognitive language learning method, and, contrary to the expectations set by the analysis of the two curricula, the IB students performed better in the translation exercises than lukio students. Both groups of students agreed that translation is a useful language learning method, and indicated that the most common dictionaries they use are bilingual Internet dictionaries. The results suggest that translation is a specific skill that requires teaching and practice, and that perhaps the translation exercises used in lukio should be developed from translating individual words and phrases to translating cultural elements. In addition, the results suggest that perhaps the IB curriculum should include the use of translation exercises (e.g., communicative translation exercises) in order to help students learn to mediate between languages and cultures rather than learn languages in isolation from each other.

Obligation des États de coopérer en droit international des cours d’eau transfrontaliers : état du droit et étude du cas Chinois

Le principe de coopération est considéré depuis longtemps comme l’une des pierres angulaires du droit international, toutefois, l’existence d’une obligation de coopérer en droit international reste encore controversée. Les ressources en eau, à cause de leur fluidité et de leurs multiples usages, démontrent toujours l’interdépendance humaine. En matière de cours d’eau transfrontaliers, la Convention de New York inclut explicitement dans son texte l’obligation générale de coopérer comme l’un de ses trois principes fondamentaux. Il nous incombe alors de voir quelle obligation de coopérer les États souverains s’imposent dans leurs pratiques ? Pour répondre à cette question, nous procédons tout d’abord à une étude positiviste du contenu normatif de l’obligation de coopérer. Nous constatons que l’incorporation de la notion de l’obligation de coopérer dans le principe de la souveraineté est une tendance manifeste du droit international qui a évolué du droit de coexistence composé principalement des règles d’abstention, au droit de coopération qui comporte essentiellement des obligations positives de facere, dont la plus représentative est l’obligation de coopérer. Néanmoins, il n’existe pas de modèle unique d’application pour tous les États, chaque bassin disposant de son propre régime coopératif. Pour mesurer l’ampleur des régimes coopératifs, nous étudions cinq paramètres : le champ d’application, les règles substantielles, les règles procédurales, les arrangements institutionnels et le règlement des différends. Quatres modèles de coopération ressortent : le mécanisme consultatif (l’Indus), le mécanisme communicateur (le Mékong), le mécanisme de coordination (le Rhin) et le mécanisme d’action conjointe (le fleuve Sénégal). Pour ce qui est de la Chine, il s’agit de l’État d’amont en voie de développement le plus important dans le monde qui a longtemps été critiqué pour son approche unilatérale dans le développement des eaux transfrontières. Nous ne pouvons pas cependant passer sous silence les pratiques de coopération qu’elle a développées avec ses voisins. Quelle est son interprétation de cette obligation générale de coopérer ? Notre étude des pratiques de la Chine nous aide, en prenant du recul, à mieux comprendre tous les aspects de cette obligation de coopérer en droit international. Afin d’expliquer les raisons qui se cachent derrière son choix de mode de coopération, nous introduisons une analyse constructiviste qui est plus explicative que descriptive. Nous soutenons que ce sont les identités de la Chine qui ont déterminé son choix de coopération en matière de cours d’eau transfrontaliers. Notre étude en vient à la conclusion que même s’il y a des règles généralement reconnues, l’obligation de coopérer reste une règle émergente en droit international coutumier. Ses modes d’application sont en réalité une construction sociale qui évolue et qui peut varier énormément selon les facteurs culturels, historiques ou économiques des États riverains, en d’autres mots, selon les identités de ces États. La Chine est un État d’amont en voie de développement qui continue à insister sur le principe de la souveraineté. Par conséquent, elle opte pour son propre mécanisme consultatif de coopération pour l’utilisation des ressources en eau transfrontalières. Néanmoins, avec l’évolution de ses identités en tant que superpuissance émergente, nous pouvons probablement espérer qu’au lieu de rechercher un pouvoir hégémonique et d’appliquer une stratégie unilatérale sur l’utilisation des ressources en eau transfrontalières, la Chine adoptera une stratégie plus coopérative et plus participative dans l’avenir.

Aplicação de microssatélites na crioconservação da diversidade genética do cavalo lusitano

O género Equus teve origem na América do Norte e alguns exemplares migraram para a Eurásia pelo Estreito de Bering, durante a última glaciação. No fim da glaciação, todos os cavalos do continente americano extinguiram-se, mas sobreviveram nas estepes da Eurásia, na Peninsula lbérica e nas florestas da Europa Ocidental e Central. O cavalo Lusitano teve a sua origem em cavalos selvagens e domesticados da Peninsula lbérica, ocorrendo uma mistura com outros animais trazidos por eventos migratórios ocorridos no passado. Os cavalos deste gene pool contribuiram para o desenvolvimento de outras raças modernas na Europa e foram mais tarde introduzidos e dispersos pelo continente Americano, tornando-se fundadores de numerosas raças do novo mundo. A raça Lusitana é uma raça equina autóctone portuguesa, com especial relevancia económica no panorama nacional e internacional. Apesar de não ser uma raça ameaçada, alguns autores defendem que a informação genealógica disponivel (pedigrees) indica que uma utilização excessiva de um reduzido número de reprodutores machos esta a diminuir a diversidade genética da raça, tendo como consequência o aumento da consanguinidade e a diminuição do tamanho efetivo da população para cerca de metade dos valores recomendados pela FAO. No entanto, a anàlise da diversidade genética com base em 16 microssatélites (Marcadores de DNA) a um grupo de 2699 machos da raça Lusitana, nascidos entre 1985 e 2010 e inscritos como reprodutores no Livro Genealógico da raça, revelou um elevado nível de diversidade, idêntico ao encontrado na maioria das raças equinas. Dada a crescente relevância da Crioconservação, omo estratégia complementar para a conservação da diversidade genética in situ, e tendo em conta que não existe criopreservação de oocitos, embriões ou sémen, do cavalo de raça Lusitana em Banco de Genes, selecionaram-se 62 machos reprodutores (garanhões) com interesse genético para a criopreservação de sémen, quer no sentido de preservar a diversidade da raça quer no da salvaguardar em caso de calamidade; ABSTRACT: The genus Equus originated in North America and some exemplary migrated to Eurasia through the Bering Strait during the last glaciation. By the end of the last glaciation, all horses on the American continent became extinct but the genus survived in the steppes of Eurasia, in the Iberian Peninsula and on the Central and West Europe forests. The Lusitano horse breed has its origins in wild and domesticated horses of the Iberian Peninsula, where a mixture with other animals brought by migratory events in the past occurred. The horses of this gene pool contributed to the development of other modern breeds in Europe and were later introduced and spread throughout the American continent, becoming founders of numerous breeds of the New World. The Lusitano horse breed, is a Portuguese native equine breed, with special economic relevance in the national and international scene. Although not being an endangered breed, some authors argue that the available genealogical information (pedigrees) indicates that an excessive use of a limited number of stallions is decreasing the genetic diversity of the breed, resulting in the increase of inbreeding and on the decrease of the effective population size to about half of the values recommended by FAO. However, the analysis of genetic diversity based on 16 microsatellites (DNA markers) in a group of 2699 males of the Lusitano horse breed, born between 1985 and 2010 and registered as Stallions in the Studbook, revealed a high level of diversity similar to that found in the majority of equine breeds. Given the growing relevance of Cryopreservation as a complementary strategy for the conservation of genetic diversity in situ and, taking into consideration the inexistence of criopreservation for oocytes, embryos and semen, in a Gene Bank, for the Lusitano horse breed, 62 breeding males (stallions) with genetic interest for semen cryopreservation were selected in order either to preserve the diversity of the breed or as safeguard in case of calamity.

Some features of the law and order model in Spain

This research is based on the hypothesis that law and order model is displacing the procedura justice system in Spain. After a thorough review of the international literature, one can observe that the traditional structure of the penal system does not seem to be capable of containing the new forms of crime. The new penal model assumes that public opinion is alarmed and unwilling to understand rational approaches to crime, so it will be likely to accept measures aimed at calming the fear of crime, through extensive control policies and penal tools to manage uncivil behavior. Objectives and methodology A measuring instrument has been developed to confirm this hypothesis, consisting of ten features that characterize the law and order model. This instrument has been used to identify examples of its ten features in the rules and practices developed at each phase of the Spanish criminal justice system. The analysis has focused specifically on public discourse about delinquency, criminal policy decisions, legislative processes, police routines, judicial dynamics, and prison system practices. Main results The investigation has shown that there are many processes and practices indicating that the law and order model is consolidating itself in the Spanish penal system. Nevertheless this process has a different intensity at each phase, being stronger at the legislative stage and softer in the penitentiary enforcement phase. One of the main conclusions is, therefore, that the designed instrument is ideal for measuring the degree of penetration of the model throughout the system. Some of the most striking results of the reasearch will be presented at the conference. Finally, proposals arise that could prevent the new model is fully seated in our criminal justice system, finding that the trend toward more severe penalties shown already unsustainable.
