Abstract:
The focus of my paper called Josef Suk (1874-1935): Works for violin is the analysis of his Fantasy g-minor op. 25 for violin and orchestra and his works for violin and piano. It was not my aim here to analyse note by note, but to comment on the basic tectonic features and point out the most interesting parts of the score. I look on formal aspects of these compositions, with the aim of gaining insight into the portrayal of the author's thoughts. I also pay attention to the harmonic side of these works. Also concerning the chamber works with the violin I provide an abridged analysis In each composition (if possible) the date of premiere and also its performer is indicated. The paper firstly provides general information on the life and work of Josef Suk and about the history of the Czech Quartet.

Abstract:
Les Pokot du Kenya sont une communauté de 190. 000 personnes (recensement 1989). Nilotes couchitiques, ils appartiennent à l'aire culturelle kalenjin. Originaires des montagnes, les Sekerr et les Cherangni, ils sont agro-pasteurs sédentaires, et ont développé traditionnellement une organisation socio-politique fondée sur huit classes d'âge aux noms récurrents, mais sans cérémonies de transmission de pouvoir pour le changement de statut de chaque classe, hormis le rite d'entrée par la circoncision. Au début du XIXème siècle, un tiers d'entre eux environ quitte les Hautes Terres vers l'est et s'installent dans les plaines de Masöl. D'autres poursuivent à l'est jusqu'à Nginyang, près des Turkana, où ils s'installent. Là certains poursuivent encore, chassant les Maasaï à l'ouest jusqu'à Kitale. Pénétrant en territoire karimojong, ils repoussent les Karimojong jusqu'à la frontière ougandaise actuelle. Leurs migration, leur nouveau mode de vie : ils sont pasteurs semi-nomades dans les plaines, le contact avec les Turkana à l'est, les Karimojong à l'ouest et leurs systèmes de classes générationnelles déterminent la formation de systèmes syncrétiques très diversifiés chez les Pokot. L'objet de la thèse est centré sur la question des exigences de telles constructions syncrétiques observées dans les trois zones de peuplement, et pour la communauté des Pokot dans son ensemble, et pour chacun de ses membres. De tels systèmes syncrétiques ne peuvent aboutir que si et seulement si les Pokot inventent les solutions les plus judicieuses aux paradoxes nés de la simultanéité des deux systèmes
In Kenya, the Pokot community is made up of approximately 190. 000persons (1989 census). They are Kushitic Nilotes and belong to the Kalenjin group. Native of the Sekerr Mountains and the Cherangani Hills, they are an agropastoral and sedentary people organized by eight age-classes with current names but without handing over ceremonies. During the first decades of the 19th century, a third of them left the mountains and migrated to the east plains. Some of them settled on the Masöl plains, while others wentt eastwards and reached Nginyang where they settled near the Turkana community. These are the East plains pastoral Pokot. Then some of them left, raided the Maasaï on the west side and chased them up to Kitale. They still went further west and reached the Karimojong territory where they chased the Karimojong out of their lands up to Amudat in Uganda, and settled there. They are the West plains Pokot. Their migrations lead them to adopt a new way of life. They became semi-nomads and pastoralists on the East and West plains. Adopting a way of life similar to the Turkana and the Karimojong, they borrowed their generation classes which determined the syncretic socio-political systems still in effect today. This thesis is focussed on the question : what do such syncretic constructions observed in the three settlement zones impose upon the Pokot community as a whole and on each of its members. Such syncretic systems can exist if, and only if, the Pokot discover the most judicious solution to their paradoxes generated by the simultaneous exigence of contradictory age classes and generation classes systems

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Sloan School of Management, 2011.
Cataloged from PDF version of thesis.
Includes bibliographical references (p. 184-200).
This dissertation is about identity and identification in organizations. I analyze the dynamic processes by which individual employees' identities are constructed in a large global Korean company (K-Co) that actively pursues a strong organizational culture and an espoused employee identity called "K-C man." First, I examine selection as the first stage of employees' identity dynamics-how the organization embodies the K-Co man identity through selection process. Data analysis showed that K-Co's selection process is organized to seek a good identity fit between an applicant and the organizationally espoused prototypical K-Co man. I compared the K-Co man identity that the organization pursues at selection with the attributes of the K-Co man identity perceived by the current individual K-Co employees. I found substantial consistency between them, which reveals the significance of selection as an initial reification of the organizationally espoused employee identity. Second, I unpack K-Co's 4-week newcomer training program as the second stage of employees' identity dynamics-how organizational identification is ignited through this early socialization process. Interviews with trainers showed that the organization uses institutionalized socialization tactics intending to impose the K-Co man identity on newcomers, thereby imbuing trainees' organizational identification, and mentor and team are two important socialization agents in this process. However, empirical evidence also revealed that individual trainees do not always react to socialization agents as the organization expected: trainees' organizational identification is achieved mainly through mentor identification, but, contrary to the organization's intention, team identification does not converge into organizational identification. Third, I analyze the employees' identity dynamics at the workplace as the third stage-how organizational identification varies among three occupational groups within K-Co (HR, Engineering, and Marketing). Even within the strong cultural context of K-Co, where the organization intends to control employees' identity work, I found the occupation each individual employee holds induces a significant variation in employees' organizational identification. Data analysis showed that how transparently K-Co's organizational identity is projected on the identities of three different occupations significantly affects each occupation incumbents' organizational identification. I also discuss how organizational tenure blurs this occupational variation in organizational identification, making all employees' identity work organization-focused.

Abstract:
Health seeking behaviour is important in older people with hypertension and overweight, in terms of managing health factors that are related to their health and illness. However, health seeking behaviour of Thai older people is not well documented. This qualitative study aimed to describe health seeking behaviour of overweight hypertensive older people. Seven older women and three men participated in this study through purposive sampling. Qualitative data were gathered via in-depth interviews and were analyzed using content analysis. The results of this study illustrated that older people started to seek health care after understanding the need to seek health care due to the severity of their symptoms. The older people began illness management by using their knowledge to take care of themselves. If management was ineffective, they would seek health care from professional health care providers and traditional healers. Additionally, family members play important roles in the health seeking behaviour of older people. In particular, Thai older people with hypertension and overweight demonstrate various health seeking behaviours that are useful to health care providers in providing appropriate care to these older people, aiming to promote better health of the older people.

Bergman, Cecilia, and Dijana Todorovic. "Hur skapar man kontinuitet i ideella organisationer : En fallstudie av Riksförbundet Sveriges Unga Katoliker." Thesis, Södertörn University College, School of Business Studies, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:sh:diva-2249.

Full text
Abstract:

Syfte: Syftet med studien är att ge rekommendationer till organisationen Riksförbundet Sveriges Unga Katoliker (SUK) om hur de kan bevara kontinuiteten inom förbundet. Rekommendationerna tillkommer genom analys av hur SUK kan ta vara på den tysta kunskapen som finns hos deras anställda och frivilliga medarbetare, samt vilka faktorer som motiverar till ett frivilligt ledarskap.

Metod: Fallstudien har en kvalitativ ansats med inslag av kvantitativa antydningar. Två intervjuer har genomförts med anställda på SUK, samt en via e-post med ytterligare en anställd. En mindre enkätundersökning har genomförts bland ideella ledare inom Stockholmregionen i SUK.

Teori: Detta kapitel börjar med en överblick över definitioner av tyst kunskap och därefter följer tvåfaktorsteorin som är en motivationsteori. Detta avsnitt redovisar teorier från Polanyi, Nonaka, samt Herzberg.

Empiri: I detta avsnitt presenteras den data som samlats in genom SUK:s hemsida, intervjuer, samt den mindre enkätundersökningen.

Analys: Under denna del analyserar vi det material som samlats in under empiri avsnittet med hjälp av de teorier som presenterats i teoriavsnittet. Data från intervjuerna ställs mot teori om tyst kunskap och enkätundersökningens resultat analyseras med hjälp av Herzbergs tvåfaktorsteori.

Slutsats: De viktigaste slutsatserna är att SUK bör bevara organisationens tysta kunskap genom att ta fram ett symboliskt organisationsspråk i form av lathundar och mallar. Kommunikationen inom organisationen måste förbättras, och SUK bör införa en praktisk del i ledarutbildningen, som också kan fungera som en överföring av tyst kunskap. Fortsatt slutsats är att motivationsfaktorerna avancemang och prestation är viktigast både enligt SUK:s frivilliga arbetare och anställda. SUK bör ta hänsyn både till motivationsfaktorer och hygienfaktorer, då båda är viktiga för att skapa kontinuitet.


Purpose:  The purpose of the essay is give the association Sweden's Young Catholics recommendations how to maintain the contingency within the organization. The recommendations arises through analysis about how Sweden's Young Catholics can preserve the tacit knowledge that the employees and volunteers have, and which factors motivates to volunteer leadership.

Methology:  For this case study we have used a qualitative method with a touch of a quantitative method. We did two interviews with employees and one through e-mail with another employee. We also did a minor poll with volunteers in the Stockholm region in Sweden's Young Catholics.

Theoretical perspective:  This chapter starts with an overview over different definitions of tacit knowledge and there after a theory about motivation. This chapter illustrates theorys by Polanyi, Nonaka, and Herzberg.

Empiric: This chapter declares material and interviews made for this thesis. Material about the organization from the website for Sweden's Young Catholics, the interviews about tacit knowledge and the poll about motivation.

Analysis: In this section we analyse all the material and interviews collected in the empiric section with help of the theories from the theoretical chapter. The interviews with the tacit knowledge and the poll with help of Herzberg's theory.

Conclusion:  The most important conclusion is that Sweden's Young Catholics should keep their tacit knowledge by developing a symbolic organizational language in shape of reference guides. The communication in the organization also has to improve and Sweden's Young Catholics should have a practical part in their leadership course which also can serve as a transfer of tacit knowledge. Other conclusions are that the most important motivation factors is promotion and performance according to both employees and volunteers. Although Sweden's Young Catholics should take both motivation factors and hygiene factors in their consideration, because they are both important for keeping the contingency in the organization.

Sallinen, P. (Pirkko). "Myocardial infarction:aspects relating to endogenous and exogenous melatonin and cardiac contractility." Doctoral thesis, University of Oulu, 2008. http://urn.fi/urn:isbn:9789514287558.

Full text
Abstract:
Abstract Melatonin is an important modulator of several physiological and behavioural processes, and it influences the function of many different tissues. Melatonin has effective antioxidative properties, but some of its actions in mammals are also mediated through the MT1 and MT2 melatonin receptors. Antioxidative properties are seen especially when the melatonin concentration is high (≥ nM), and melatonin's affinity for its receptors appears at lower concentrations (pM). Recently, the involvement of melatonin in protecting the heart against cardiac diseases, including myocardial infarction (MI), has been brought out. MI alters the structure and function of myocardium, attenuating for example cardiac contractility by affecting the amount and function of the essential Ca2+ handling proteins, dihydropyridine receptor (DHPR), ryanodine receptor (RyR2) and sarco-endoplasmic reticulum (SR) Ca2+-ATPase2 (SERCA2). MI also evokes many adaptive responses in organisms, such as elevated production of atrial and brain natriuretic peptides (ANP and BNP). In this thesis, the expression of MT1 and MT2 receptor mRNAs was investigated in several rat tissues. Furthermore, the effect of MI and exogenous melatonin on the rat endogenous melatonin and on the expression of cardiac MT1, MT2, DHPR, RyR2 and SERCA2 proteins was evaluated. The concentrations of ANP and BNP were also measured after post-MI melatonin administration. The results show the expression of MT1 and/or MT2 receptor mRNAs in the hypothalamus, retina, small intestine, liver and heart, which indicates that at least some effects of melatonin could be mediated through the receptors in these tissues. Melatonin synthesis in the pineal gland increased rapidly in response to MI, supporting an important role of endogenous melatonin in protecting the heart after MI. Furthermore, exogenous melatonin altered the mRNA expression of DHPR, RyR2 and SERCA2 after MI, suggesting that melatonin might contribute to the post-infarction cardiac contractile function. The results also revealed a novel, positive relationship between melatonin and ANP, and thereby bring out one more possible way of melatonin to protect the heart against MI-induced injuries. Taken together, the present thesis (i) supports the notion that melatonin is an important endogenous protective agent of the organism, and (ii) extends our knowledge of melatonin's post-infarction cardioprotective actions
Tiivistelmä Melatoniini osallistuu monien fysiologisten toimintojen ja käyttäytymisen säätelyyn sekä vaikuttaa useiden eri kudosten toimintaan. Melatoniini on tehokas antioksidantti, mutta jotkut sen vaikutuksista välittyvät myös MT1 ja MT2 melatoniini reseptorien kautta. Antioksidatiiviset vaikutukset tulevat esiin erityisesti silloin, kun melatoniinin pitoisuus on korkea (≥ nM). Alhaisemmilla pitoisuuksilla (pM) on puolestaan havaittavissa melatoniinin sitoutuminen reseptoreihinsa. Viime aikoina on tullut esille melatoniinin mahdollinen suojavaikutus sydänsairauksia, kuten sydäninfarkteja, vastaan. Sydäninfarkti muuttaa sydänlihaksen rakennetta ja toimintaa esimerkiksi vaikuttamalla supistuksen kannalta välttämättömien proteiinien, dihydropyridiini reseptorin (DHPR), ryanodiini reseptorin (RyR2) ja sarko-endoplasmakalvoston Ca2+-ATPaasi2:n (SERCA2) lukumääriin ja toimintaan, ja sitä kautta muun muassa heikentää sydämen supistuvuutta. Sydäninfarkti laukaisee elimistössä myös monia adaptiivisia vasteita, kuten eteispeptidin (ANP) ja aivojen natriureettisen peptidin (BNP) lisääntyneen erityksen. Tässä väitöstyössä tutkittiin MT1 ja MT2 reseptorien mRNAn ilmentymistä useissa rotan eri kudoksissa. Lisäksi tutkittiin sydäninfarktin ja eksogeenisen melatoniinin vaikutuksia rotan endogeeniseen melatoniiniin sekä sydämen MT1, MT2, DHPR, RyR2 ja SERCA2 proteiinien ekspressioon. Myös ANP ja BNP pitoisuudet mitattiin. Tulokset osoittivat MT1 ja/tai MT2 reseptori mRNAn ilmentymisen hypotalamuksessa, silmän verkkokalvolla, ohutsuolessa, maksassa ja sydämessä, minkä perusteella ainakin osa melatoniinin vaikutuksista saattaisi olla reseptorivälitteisiä näissä kudoksissa. Tulosten mukaan käpyrauhasen melatoniinisynteesi lisääntyi nopeasti sydäninfarktin jälkeen, mikä tukee käsitystä endogeenisen melatoniinin tärkeästä roolista infarktin jälkeisessä sydämen suojauksessa. Lisäksi eksogeeninen melatoniini muutti DHPR:n, RyR2:n ja SERCA2:n mRNA ekspressiota infarktin jälkeen, mikä voisi merkitä, että melatoniini saattaa vaikuttaa infarktin jälkeiseen sydämen supistuvuuteen. Tulosten osoittama positiivinen riippuvuus melatoniinin ja ANP:n välillä tuo puolestaan esille yhden uuden mahdollisen keinon, jonka kautta melatoniini voisi suojata sydäntä infarktin aiheuttamia vaurioita vastaan. Yhteenvetona voidaan todeta, että tämä väitöstyö (i) tukee käsitystä, että endogeenisella melatoniinilla on tärkeä merkitys elimistön suojaamisessa, ja (ii) laajentaa tietämystämme infarktin jälkeisistä melatoniinin sydäntä suojaavista vaikutuksista

Pettersson, Ulf, and Magnus Zetterlund. "Är svenska aktiepriser trögrörliga? : En studie av tidsförskjutningar i prissättningen av värdepapper i samband." Thesis, Linköping University, Department of Management and Engineering, 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-11090.

Full text
Abstract:

Bakgrund

Richard J. Rendleman, Charles P. Jones & Henry A. Latané påvisade i en studie år 1982 med hjälp av en regressionsmodell att tidsförskjutningar i prissättningen av aktier existerat på den amerikanska marknaden vid kvartalsresultat som avvek från en trend. Det inspirerade oss att med samma metod undersöka om liknande tidsförskjutningar även existerat på den svenska marknaden.

Syfte

Syftet med denna uppsats är att empiriskt studera om det existerat tidsförskjutna aktieprisjusteringar kvartalsvis, baserade på standardiserade oförväntade kvartalsresultat respektive standardiserade oförväntade kassaflöden, på den svenska aktiemarknaden under åren 2004-2006. Om sådana tidsförskjutningar av prisbildning existerat avser vi även att diskutera dem utifrån teorier om behavioral finance.

Genomförande

Med linjär regression estimeras EPS respektive kassaflöden utifrån historiska data. Estimeringarnas avvikelse från rapporterade data jämförs sedan med aktiekursutveckling för att se om samband föreligger mellan storleken på avvikelserna och efterföljande tidsförskjutning.

Resultat

Under tidsperioden 2004-2006 påvisar vi tidsförskjutningar med standardiserade oförväntade kvartalsresultat men inte med standardiserade oförväntade kassaflöden.


Background

Richard J. Rendleman, Charles P. Jones & Henry A. Latané presented a study in 1982 where they showed anomalies on the American stock exchange when using standardized unexpected earnings. Their result inspired us to do a similar research on the Swedish stock exchange.

Purpose

The purpose of this study is to do an empirical study of the existence of drifts in stock price adjustments, based on standardized unexpected earnings and standardized unexpected cash-flows on the Swedish stock exchange during the years 2004-2006. If anomalies are discovered we intend to discuss them in terms of behavioral finance.

Implementation

With a linear regression we estimate EPS respective cash-flow from historical data. The deviations from quarterly reported data are compared with the development of stock-prices.

Conclusion

During the time period 2004-2006 we show that anomalies have existed when standardized unexpected earnings are applied and that no anomalies can be found with standardized unexpected cash-flows.

Abstract:
Nous avons évalué la réponse des plantes de sous-bois à l’exclusion expérimentale du cerf de Virginie dans des forêts du sud du Québec, après environ 30 ans de densités élevées. Dans six érablières, un exclos et un témoin ont été établis en 1998 sous couvert forestier et de même en 2003 sous trouée. Nous avons évalué les impacts du cerf sur la richesse spécifique, l’abondance et la biomasse de différents groupes de plantes. Aucune différence significative entre les traitements n’a été observée pour ces différentes variables après huit ans sous couvert végétal ou trois ans sous trouée, à l’exception de l’abondance totale et des semis. Toutefois, les Trillium erectum étaient devenus plus grands et se reproduisaient davantage dans les exclos que les témoins sous couvert forestier. Dans l’ensemble, les plantes n'ont pas répondu suite à l’exclusion du cerf, peut-être en raison de la faible luminosité en sous-bois.
We examined the response of understory plants to deer exclusion in maple-dominated forests of southern Québec following nearly 30 years of deer overabundance. Six maple forests were selected for the study and at each site one deer exclosure and one control were established in 1998. One exclosure and one control at each of the same sites were established in 2003 under recent gap openings. We investigated deer impacts on the richness, abundance, and aboveground biomass of different plant groups. None of these variables differed significantly between treatments over the years under both forest cover and gaps, except for tree seedlings and total plant abundance under gaps. Trillium erectum recovered partially as individuals were taller and reproduced more frequently in deer exclosures under forest cover. Overall, our results suggest that plant groups did not recover from deer exclusion, likely because of low light levels that prevail in maple-dominated forests.

Abstract:
Les arts plastiques du Sud-Cameroun et du pays Beti en particulier n'ont jusqu'ici pas fait l'objet d'études poussées, ceci a fait croire à certains chercheurs que cette région n'a pas développé une culture artistique respectable. De même, sur la plupart des cartes stylistiques d'Afrique Equatoriale, le style beti est absent ou simplement représenté par le style fang. Pourtant, l'art Beti se distingue de l'art Fang. Aussi, dans cette étude de la sculpture chez les anciens Beti, nous mettons en relief ses manifestions et ses messages. Cette approche morpho-stylistique, esthétique et fonctionnelle se fait en rapport avec les groupes voisins « pahouinisés » ou non, car nous attachons une grande importance aux zones de contact et de réseaux où naissent parfois des «styles de synthèse ». Enfin, la sculpture en apparaît ici comme une vitrine susceptible de permettre une lecture pertinente du passé de ces populations, de leurs migrations et des contacts avec les peuples voisins.

Sympathetic solar flares are events occurring nearly simultaneously at distinct active regions with physical connection between them. Two flares that occurred on March 8, 2011 in active regions NOAA (National Oceanic and Atmospheric Administration) 11163 (N17W91) and AR 11165 (S20W91) is being studied. The larger flare occurred in the Southern region and was preceded by a smaller flare in the Northern region, about 5 minutes before. Both events were observed by RHESSI. The first explosion was detected by SST in the AR of north hemisphere, in two stages. There are also EUV SDO high cadence images that exhibit a distinct rapid flash coinciding with the SST burst as well as clear large scale magnetic connections between the two active regions. Three possible flare triggering agents from the Northern region towards the Southern region are being investigated: (a) hydrodynamic waves along the large coronal interconnecting magnetic structure, (b) surface Moreton-like shock waves, (c) plasma echoes.
Explosões solares simpatéticas são eventos que ocorrem quase simultaneamente, em regiões ativas distintas. Este trabalho apresenta o estudo de duas explosões solares que ocorreram no dia 8 de março de 2011, nas regiões ativas NOAA 11163 (N17W91) e 11165 (S20W91), entendidas como um evento simpatético característico. A maior explosão ocorreu na região sul, precedida por uma explosão menor na região norte, 5 minutos antes. Ambas detecções foram observadas em raios-X duros pelo satélite RHESSI. A primeira explosão também foi detectada pelo SST na RA do hemisfério norte. Imagens do SDO/AIA em EUV de alta cadência exibem um flash rápido e distinto, coincidente com a detecção do SST. As observações mostram que existem conexões magnéticas em grande escala entre as duas regiões ativas. Isso nos permitiu estudar três possíveis agentes de ativação entre as duas regiões ativas, sendo investigados, então, os seguinte mecanismos de ativação: (i) ondas hidrodinâmicas, ao longo da grande estrutura magnética coronal; (ii) ondas de choque do tipo Moreton, e, (iii) eco de plasma.

Abstract:
La majorité des plantes d’ombre d’intérêt médicinal sont récoltées en milieu naturel, menaçant ainsi les populations naturelles. Cette étude visait à évaluer l'impact des trouées et des caractéristiques chimiques du sol sur l’émergence, la croissance et la production de composés actifs de quatre plantes médicinales : Actaea racemosa, Sanguinaria canadensis, Caulophyllum thalictroides et Asarum canadense. Les boutures de rhizome ont été récoltées deux années après leur plantation en érablière. Les régressions multiples ont indiqué que la croissance de trois des espèces augmente avec l’irradiance et que toutes ont davantage répondu aux éléments reliés à l’acidité plutôt qu’à la richesse du sol. Les concentrations en composés actifs des rhizomes et des racines varient peu ce qui fait que leur contenu total augmente avec la biomasse. La création de trouées et le chaulage semble donc des interventions souhaitées pour augmenter le rendement en biomasse et en composés actifs chez ces espèces.

Full text
Abstract:
This research is designed to develop and investigate newly defined problems: the Maximum Convex Sum (MCS), and its generalisation, the K-Maximum Convex Sum (K-MCS), in a two-dimensional (2D) array based on dynamic programming. The study centres on the concept of finding the most useful informative array portion as defined by different parameters involved in data, which is generically expressed in this thesis as the Maximum Sum Problem (MSP). This concept originates in the Maximum Sub-Array (MSA) problem, which relies on rectangular regions to find the informative array portion. From the above it follows that MSA and MCS belong to MSP. This research takes a new stand in using an alternative shape in the MSP context, which is the convex shape. Since 1977, there has been substantial research in the development of the Maximum Sub-Array (MSA) problem to find informative sub-array portions, running in the best possible time complexity. Conventionally the research norm has been to use the rectangular shape in the MSA framework without any investigation into an alternative shape for the MSP. Theoretically there are shapes that can improve the MSP outcome and their utility in applications; research has rarely discussed this. To advocate the use of a different shape in the MSP context requires rigorous investigation and also the creation of a platform to launch a new exploratory research area. This can then be developed further by considering the implications and practicality of the new approach. This thesis strives to open up a new research frontier based on using the convex shape in the MSP context. This research defines the new MCS problem in 2D; develops and evaluates algorithms that serve the MCS problem running in the best possible time complexity; incorporates techniques to advance the MCS algorithms; generalises the MCS problem to cover the K-Disjoint Maximum Convex Sums (K-DMCS) problem and the K-Overlapping Maximum Convex Sums (K-OMCS) problem; and eventually implements the MCS algorithmic framework using real data in an ecology application. Thus, this thesis provides a theoretical and practical framework that scientifically contributes to addressing some of the research gaps in the MSP and the new research path: the MCS problem. The MCS and K-MCS algorithmic models depart from using the rectangular shape as in MSA, and retain a time complexity that is within the best known time complexities of the MSA algorithms. Future in-depth studies on the Maximum Convex Sum (MCS) problem can advance the algorithms developed in this thesis and their time complexity.

Abstract:
Les mutations profondes observées au cours des vingt-cinq dernières années dans le monde de l'électronique ont actuellement cours en biologie, en partie grâce aux biotechnologies. Le concept communément appelé "laboratoire sur puce" (Lab-On-Chips, LOC) doit son essor à l'effort considérable qui a été mené en matière de développement des technologies de micro-fabrication. Le nombre d'outils technologiques disponibles actuellement pour la fabrication de réseaux microfluidiques est important mais la réalisation de systèmes complexes tridimensionnels reste encore un challenge. Le développement des micro- et nanotechnologies à de nouveaux matériaux comme les polymères, et en particulier la SU-8, a permis d'ouvrir la voie à une intégration plus élaborée telle que nous la présentons dans ce travail de thèse. Nous y exposons la démarche et les détails d'une approche consistant en la conception, la modélisation et la fabrication de dispositifs d'actionnement magnétique intégrés au sein de réseaux microfluidique en SU-8 pour la manipulation de billes magnétiques ; le tout étant élaboré sur un substrat souple de type PET. Le développement des outils de caractérisations des systèmes réalisés a également été présenté. Ils ont permis la mise en place d'un protocole expérimental visant à évaluer et quantifier les différents paramètres électriques, thermiques, fluidiques et magnétiques concourant à obtenir un dispositif LOC efficient dans la circulation de fluides, le piégeage de billes magnétiques, leur transfert d'une zone à un autre et leur orientation guidée vers des canaux privilégiés
The profound changes observed over the last twenty five years in the electronics world currently haves courses in biology, partly thanks to biotechnology. The concept commonly called "lab-on-chip" (LOC) owes its growth to the considerable effort that has been conducted on technology development of micro-fabrication. The number of technological tools currently available for the manufacture of microfluidic networks is important but the realization of complex three-dimensional systems remains a challenge. The development of micro and nanotechnology for new materials such as polymers, and especially the SU-8, opened the way for more sophisticated integration as we present it in this work. We expose the details of an approach in the design, modeling and fabrication of magnetic actuators integrated into SU-8 microfluidic networks for magnetic beads handling; all being developed on a flexible substrate of PET. The development of characterizations tools systems was also presented. They permit the establishment of an experimental protocol to assess and quantify the different electrical, thermal, fluidic and magnetic parameters contributing to obtain a LOC device in the efficient movement of fluids, trapping of magnetic balls, transfer of one area to another and to their orientation through preferred channels

Abstract:
Ad oggi la pressione umana sui sistemi fluviali ha mostrato gravi livelli di vulnerabilità idrica per circa 4,8 miliardi di persone. L’aumento crescente dell’utilizzo di questa risorsa in combinazione con i cambiamenti climatici potranno aggravare tale situazione. Precedenti studi hanno valutato l’entità degli impatti antropici sui sistemi idrici analizzando l’estensione del problema e la sua entità al giorno d’oggi. In questo elaborato di tesi si è tentato di valutare come la pressione antropica sui sistemi fluviali si sia storicamente sviluppata per cercare di comprendere come è probabile che progredisca nel tempo. Dato un corso d’acqua e la sua area contribuente, la pressione antropica su tale corso è definita come il rapporto tra la presenza umana e la portata naturale generata all’interno della stessa area contribuente. La presenza umana viene stimata attraverso le luci artificiali notturne e diurne mentre, i valori di portata sono ottenuti direttamente da database internazionali. L’evoluzione della pressione antropica sui corsi d’acqua viene invece valutata attraverso l’Indice di Pressione Antropica Differenziale sui corsi d’acqua (DHP) e viene calcolato come la derivata della pressione umana sui sistemi fluviali. I valori di DHP sono stimati per alcuni bacini idrografici situati nel sud-est asiatico, in particolare Cina e Birmania, all’interno del periodo 1994-2015. Tale area è stata scelta sulla base di un trend positivo di crescita demografica in modo da valutare l’evoluzione temporale dell’impatto antropico sui sistemi idrici. L’analisi ha mostrato per tutti i bacini un incremento annuale significativo della pressione antropica che fa ipotizzare che nel prossimo futuro la pressione sui sistemi fluviali continuerà a crescere. Attraverso l’introduzione della variabilità annuale delle portate i livelli di pressione antropica sui corsi d’acqua risultano maggiormente critici di quelli che si otterrebbero attraverso l’utilizzo di portate stazionarie.

Abstract:
Nouvel espace politique, économique et professionnel, le Marché commun du Sud (Argentine, Brésil, Paraguay et Uruguay) est également un nouvel espace linguistique et culturel, lieu de références plurielles. L’idée que le sentiment d’appartenance au Marché commun est contenu en germe dans chaque culture nationale n’est qu’une pure fiction. La résurgence des replis identitaires dans les États-membres démontre d’ailleurs que l’identité mersosurienne ne peut être ni universelle, ce qui reviendrait à nier les différences, ni particulière, ce qui contribuerait à les exacerber. On le voit bien, le problème est loin d’être simple. L’issue de cette quête identitaire dépendra de la capacité à ménager une place à la diversité culturelle sans perdre le sens d’une citoyenneté mercosurienne qui soit un lieu d’allégeance commune. Nous nous proposons à travers cette recherche à partir du cas du Mercosur et du Chili un ensemble de questions relatives à l’articulation entre les politiques linguistiques nationales (ou des absences apparentes de politiques linguistiques nationales) et les développements économiques macro-régionaux, sur fond de régionalisation/mondialisation d’une part, d’affirmations communautaires, identitaires et locales d’autre part. De ce point de vue, nous verrons que le Mercosur – tel qu’il est dans les faits mais aussi tel qu’il est représenté – constitue moins un moteur central qu’une délimitation dynamique d’un espace en mouvement où il opère comme révélateur et accélérateur voire instrument de conscientisation pour une réflexion et des initiatives intéressant la politique des langues
Being a new political, economical and professional area, the common Market of the South, is also a new linguistic and cultural area, a place of many references. Defined by is multilingualism and its many cultures, the Mercosur maintains its meaning through its respect of languages and cultures. The idea that the sense of belonging to the common Market is found in embryonic form in each national culture, is pure fiction. Besides, the resurgence of the innermost identities within the member-States proves that the market identity can be neither universal, which would mean denying the differences, nor specific, which would help to exacerbate them. It is obvious that the problem is far from being simple. The outcome of this quest for identity will depend on the ability to carefully handle an area of cultural diversity, a place of common allegiance, without losing the sense of Mercosurian citizenship. Through this research, and taking the case of the Mercosur and Chile, we intend to tackle a group of questions regarding the connection between the national linguistic policies (or visible lack of national linguistic policies) and the macro economical developments against background of community, identity and local assertion on the other hand. From this standpoint, we shall see the Mercosur - not only as it is factually but also as it is represented – constitutes less of a central force than a dynamic boundary of a moving area where it proceeds as a pointer and a catalyst, or even as an instrument to consciousness towards a reflection and initiative concerning the polities of language

Abstract:
La conservation de la biodiversité est une des valeurs mises à l’avant-plan de l’aménagement forestier. Des traitements ayant comme objectif d’atténuer certains impacts négatifs de l’exploitation forestière sur la faune sont fréquemment réalisés afin de répondre à ces valeurs. J’ai étudié les effets d’éclaircies précommerciales (EPC), avec et sans mesures d’atténuation, sur les oiseaux chanteurs et les paramètres de végétation. Les mesures d’atténuation étaient essentiellement des réductions d’intensité des coupes. Un dispositif expérimental de type before-after-control-impact (BACI) a été mis sur pied par une équipe multidisciplinaire afin de répondre aux objectifs. Le dispositif comportait en moyenne 19 répétitions des traitements suivants : témoin, EPC régulière, EPC avec mesures d’atténuation faunique. Je n’ai trouvé aucune différence d’occurrence des différentes guildes d’oiseaux chanteurs en nidification entre les EPC avec mesures d’atténuation faunique et les EPC régulières. Les résultats suggèrent également que les EPC régulières pratiquées dans cette région ont un effet négligeable sur les guildes par rapport à des peuplements non éclaircis. Pour les paramètres de végétation, les travaux n’ont influencé significativement que l’obstruction visuelle latérale et le couvert forestier vertical de conifères. Cette étude ne remet pas en cause les conclusions d’études similaires pratiquées dans d’autres régions, mais indique que les EPC peuvent être pratiquées sans impact majeur sur les oiseaux forestiers de la région concernée. Mots clés : Éclaircie précommerciale, oiseaux chanteurs, dispositifs expérimentaux (BACI), mesures d’atténuation, biologie de la conservation, aménagement.
Biodiversity conservation is a key aspect of forest management. Silvicultural regimes that aim to mitigate some of the negative effects of logging on wildlife are often used to meet biodiversity conservation objectives. I studied the effects of wildlife mitigation measures for precommercial thinning (PCT) on songbirds and vegetation to check whether these measures have the desired effect. A before-after-control-impact (BACI) experimental design was established by a multidisciplinary team to assess the objectives. The design consisted of an average of 19 replicates for the following treatments: control, regular PCT, and wildlife-mitigated PCT. I found no difference in nesting songbird guilds between wildlife-mitigated PCT and regular PCT. The results also suggest that regular PCT had little or no effect on guilds, when compared to unthinned stands. The lack of an significant effect on birds likely arose from the weak effect of the treatments on vegetation, which affected only lateral visual obstruction and coniferous vertical forest cover. This study does not question the findings of similar studies performed in other regions, but indicates that PCT can be practiced without major impacts on forest songbirds in the region concerned with this study. Keywords : Precommercial thinning, songs birds, experimental design (BACI), mitigation, conservation biology, management.

Abstract:
The magnetocaloric and thermomagnetic properties of the MnNiGe1-xAlx, Ni50Mn35(In1−xCrx)15 and (Mn1−xCrx)NiGe1.05 systems have been studied by x-ray diffraction, differential scanning calorimetry (DSC), and magnetization measurements. Partial substitution of Al for Ge in MnNiGe1−xAlx results in a first-order magnetostructural transition (MST) from a hexagonal ferromagnetic to an orthorhombic antiferromagnetic phase at 186 K (for x = 0.09). A large magnetic entropy change of ∆SM = -17.6 J/kg K for ∆H = 5 T was observed in the vicinity of TM = 186 K for x = 0.09. This value is comparable to those of well-known giant magnetocaloric materials, such as Gd5Si2Ge2, MnFeP0.45As0.55, and Ni50Mn37Sn13 [1]. The values of the latent heat (L = 6.6 J/g) and corresponding total entropy changes (∆ST = 35 J/kg K) have been evaluated for the MST using DSC measurements. Large negative values of ∆SM of -5.8 and -4.8 J/kg K for ∆H = 5 T in the vicinity of TC were observed for x = 0.09 and 0.085, respectively. Partial substitution of Cr for Mn in(Mn1−xCrx)NiGe1.05 results in a MST from a hexagonal paramagnetic to an orthorhombic paramagnetic phase near TM ~ 380 K (for x = 0.07). Partial substitution of Cr for In in Ni50Mn35(In1−xCrx)15 shifts the magnetostructural transition to a higher temperature (TM ~ 450 K) for x = 0.1. Large magnetic entropy changes of ∆SM = -12 (J/kgK) and ∆S = -11 (J/kgK), both for a magnetic field change of 5 T, were observed in the vicinity of TM for (Mn1−xCrx)NiGe1.05 and Ni50Mn35(In1−xCrx)15, respectively. The concentration-dependent (T-x) phase diagram of transition temperatures (magnetic, structural, and magnetostructural) has been generated using magnetic, XRD, and DSC data. The role of magnetic and structural changes on transition temperatures are discussed.

Fondamental dans chacun des quatre pays du mercosur (argentine, bresil, paraguay, uruguay) et en plein developpement, l'agribusiness (de la production agricole a la production alimentaire) permet a cet ensemble regional en cours d'integration, d'etre l'un des principaux animateurs du marche agricole mondial. Le mercosur est, notamment, le premier exportateur mondial de produits derives de soja etde tournesol (tourteaux et huiles). Dans ce contexte regional renouvele et dans le cadre de la globalisation des activites de production, les acteurs agro-industriels, dont ceux de la trituration, se confrontent sur le << marche des lieux >> qu'est l'espace economique elargi. Or, le degre de << localisation >> joue sur le degre de mobilite spatiale : le rapport au territoire peut penaliser ou peut favoriser l'adaptation. Et, en << se territorialisant >>, les firmes multinationales bouleversent les habitudes productives des acteurs nationaux (societes familiales, secteur cooperatif). Pour analyser les restructurations en cours, l'angle d'approche choisi est la dynamique territoriale des acteurs agro-industriels et l'hypothese de strategies d'adaptation a la mondialisation differentes selon l'ancrage territorial est avancee : strategies difficiles pour les acteurs cooperatifs, possibles pour les entreprises nationales, faciles pour les firmes multinationales. Les comportements spatio-economiques specifiques qui en resultent sont repertories : disparition, statu quo, diversification, specialisation, multinationalisation. De la mise a l'epreuve de ce modele d'analyse sur un echantillon de triturateurs implantes en argentine, trois enseignements se degagent : une localisation logique dans les terminaux portuaires, les defis croissants de l'approvisionnement en graines et de l'amelioration de la logistique de transport, et l'absence de projets de productions plus integrees (viandes blanches) comme au bresil.

Abstract:
Polyoxoniobates (PONbs) are a small family of highly electron-rich clusters. The development of new solids composed of these clusters have applications in green energy and electronics. However, the high charge environment of PONbs typically requires alkaline synthetic conditions that are unsuitable for introducing other metals and organic molecules, making synthesis of new systems difficult. To date, very few transition metals and organic ligands have been incorporated into these PONb solids, and lanthanide metal inclusion, which generally improves photoconductivity due to longlived f-orbital excitations, has not yet been fully realized. Here, the synthesis of a new class of lanthanide niobate cluster [Ln4(H2O)8(SO4)5(NbO3)2]·3H2O; Ln= Dy, Tb under acidic conditions is reported. Structures were determined by crystallography and time-dependent density functional theory (TD-DFT) was used to provide insight into photo-induced electronic transitions. Supporting computational methods that are currently being developed for modeling these emerging cluster systems are described.

Abstract:
Le concept d'inversion tectonique a été introduit par les géologues pétroliers de la Mer du Nord, pour traduire l'aspect anormal de grabens formant des hauts structuraux par rapport à leurs plates-formes. La compréhension des mécanismes de l'inversion et des paramètres influents sur ces mécanismes est très importante à la fois pour l'industrie pétrolière, afin de mieux connaÎtre la genèse et le piégeage des hydrocarbures dans les grabens inversés, mais aussi pour la recherche fondamentale, quant à leur signification géodynamique. En effet, étudier l'inversion tectonique des bassins sédimentaires, et tenter d'en comprendre le fonctionnement, c'est aussi aborder la déformation continentale sous l'un d~ ses aspects fondamentaux: la réactivation des structures héritées d'échelle crustale. La zone d'étude considérée dans ce travail est le Sud de la Mer du Nord, et plus particulièrement le "Broad Fourteens basin" qui fait partie des grabens hollandais. Les grabens de la Mer du Nord se sont formés entre le Trias et le Crétacé inférieur et ont été inversés au Crétacé supérieur et au Tertiaire. La variation de leur orientation et la présence pour certains d'entre eux' d'un niveau de décollement supracrustal, le sel Zechstein, en font des structures très diversifiées. L'analyse précise des données de sub-surface du "Broad Fourteens Basin" a d'abord permis d'identifier les paramètres les plus importants de l'inversion tectonique. Plusieurs séries d'expériences sur modèles analogiques ont ensuite été réalisées pour étudier les effets de ces paramètres sur le développement des structures d'inversion. Les expériences ont montré que l'inversion d'un graben d'échelle crustale par réactivation de failles normales à fort pendage ne peut se faire qu'a obliquité a entre graben et compression inférieure à 45°. L'inversion se soit par une partition de la déformation entre décrochement sur le normales héritées et chevauchement néoformés (a > 45°), soit par une réactivation des failles normales en chevauchements oblique (a < 45°). Lorsque la couverture est décollée du socle, le chevauchement du remplissage du graben sur les plates-formes est localisé sur les bordures. Cet effet est accentué par la présence de diapirs de bordure de graben lorsqu'ils existent. Cette analyse structurale détaillée, menée sur le "Broad Fourteens Basin", a ensuite été étendue aux autres grabens des domaines Centre et Sud de la Mer du Nord. L'ensemble des données cinématiques obtenues est utilisé pour proposer une interprétation géodynamique de l'inversion des grabens de la Mer du Nord en tant qu'e conséquence de la collision Alpine.
