Les difficultés d’application du droit international au conflit du Haut-Karabagh : effectivités et causes géopolitiques

Conflit présenté comme gelé, la guerre du Haut-Karabagh n’en est pas moins réelle, s’inscrivant dans une géopolitique régionale complexe et passionnante, nécessitant de s’intéresser à l’histoire des peuples de la région, à l’histoire des conquêtes et politiques menées concomitamment. Comprendre les raisons de ce conflit situé aux limites de l’Europe et de l’Asie, comprendre les enjeux en cause, que se soit la problématique énergétique ou l’importance stratégique de la région du Caucase à la fois pour la Russie mais également pour les Etats-Unis ou l’Union Européenne ; autant de réflexions que soulève cette recherche. Au delà, c’est l’influence réciproque du droit international et du politique qui sera prise en compte, notamment concernant l’échec des négociations actuelles. Les difficultés d’application du droit international à ce conflit sui generis se situent à plusieurs niveaux ; sur le statut de la région principalement, mais également sur les mécanismes de sanctions et de réparations devant s’appliquer aux crimes sur les personnes et les biens et qui se heurtent à la classification difficile du conflit.

Le tonneau des Danaïdes ou de l’européanisation à l’Est : la grande corruption en Roumanie – types, causes, conséquences

Pourquoi la Roumanie ne réussit-elle pas l'épreuve de l'européanisation? À travers quatre études de cas, ce mémoire souligne le rôle central occupé par les partis politiques dans le développement de la corruption en Roumanie. En adaptant la théorie créée par Jonathan Pinto, Carrie Leana et Frits Pil, il montre que le type le plus répandu de corruption n'est pas individuel mais organisationnel et se propage à travers les partis. Plus précisément, les études de cas servent à comparer les phénomènes de l'Organisation d'Individus Corrompus (OIC) et de l'Organisation Corrompue (OC). En Roumanie, les deux types coexistent. Toutefois, de par l’étendue et la puissance supérieure dans le fonctionnement de l’OC par rapport à l’OIC, de par la définition et tel que le montre l'analyse des études de cas choisies, le phénomène de l’Organisation Corrompue dans sa manifestation à l'intérieur des partis politiques a plus de conséquences négatives sur le développement économique, politique et sur l’intégration européenne du pays comprise dans le sens d’idéal démocratique et de modernité dont tout État membre de l’Union européenne tente de se rapprocher.

Les causes des violences ethniques de 2010 au Kirghizistan

Suivant les violences du sud du Kirghizistan en 2010, plusieurs auteurs de même que des médias ont décrit les affrontements entre les Ouzbèks et les Kirghizes comme étant dûs à des manipulations de l’ethnicité par les élites de la région. Ce travail de mémoire de maîtrise analyse l’influence des élites dans la société kirghize, elle évalue la capacité de celles-ci à mobiliser les gens pour quelque chose d’aussi radical que des violences ethniques. L’emprise politique et économique des élites kirghizes et ouzbèkes sur la société est donc confrontée à des facteurs de mobilisation plus émotifs. La théorie de Scott Radnitz sur le clientélisme et sur la capacité qu’ont les élites à réunir une foule majeure pour des regroupements publics sera notamment examinée et mise en opposition à des théories qui attribuent des causes plus émotionnelles aux affrontements. Cette analyse démontre que la théorie de Scott Radnitz indique une bonne première piste à suivre pour l’étude de toute mobilisation au Kirghizistan. Cependant, pour la mobilisation menant à des violences ethniques, il faut apporter une petite nuance afin d’incorporer les aspects émotionnels à la mobilisation.

Modelling and Analysis of Recurrent Event Data with Multiple Causes

This thesis Entitled “modelling and analysis of recurrent event data with multiple causes.Survival data is a term used for describing data that measures the time to occurrence of an event.In survival studies, the time to occurrence of an event is generally referred to as lifetime.Recurrent event data are commonly encountered in longitudinal studies when individuals are followed to observe the repeated occurrences of certain events. In many practical situations, individuals under study are exposed to the failure due to more than one causes and the eventual failure can be attributed to exactly one of these causes.The proposed model was useful in real life situations to study the effect of covariates on recurrences of certain events due to different causes.In Chapter 3, an additive hazards model for gap time distributions of recurrent event data with multiple causes was introduced. The parameter estimation and asymptotic properties were discussed .In Chapter 4, a shared frailty model for the analysis of bivariate competing risks data was presented and the estimation procedures for shared gamma frailty model, without covariates and with covariates, using EM algorithm were discussed. In Chapter 6, two nonparametric estimators for bivariate survivor function of paired recurrent event data were developed. The asymptotic properties of the estimators were studied. The proposed estimators were applied to a real life data set. Simulation studies were carried out to find the efficiency of the proposed estimators.

Causes of legume-rotation effects in increasing cereal yields across the Sudanian, Sahelian and Guinean zone of West Africa

On-farm experiments and pot trials were conducted on eight West African soils to explore the mechanisms governing the often reported legume rotation-induced cereal growth increases in this region. Crops comprised pearl millet (Pennisetum glaucum L.), sorghum (Sorghum bicolor Moench), maize (Zea mays L.), cowpea (Vigna unguiculata Walp.) and groundnut (Arachis hypogaea L.). In groundnut trials the observed 26 to 85% increases in total dry matter (TDM) of rotation cereals (RC) compared with continuous cereals (CC) in the 4th year appeared to be triggered by site- and crop-specific early season differences in nematode infestation (up to 6-fold lower in RC than in CC), enhanced Nmin and a 7% increase in mycorrhizal (AM) infection. In cowpea trials yield effects on millet and differences in nematode numbers, Nmin and AM were much smaller. Rhizosphere studies indicated effects on pH and acid phosphatase activity as secondary causes for the observed growth differences between RC and CC. In the study region legume-rotation effects on cereals seemed to depend on the capability of the legume to suppress nematodes and to enhance early N and P availability for the subsequent cereal.

Causes of legume rotation induced yield increases in cereals grown on West African soils

This study was conducted to investigate soil biological and chemical factors that give rise to cereal yield enhancing effects of legume rotations on sandy, nutrient poor West African soils. The aim was not only to gain more information on the role of legume residues and microorganisms in the soil nutrient cycle. But the study aimed at evaluating if differences in substrate qualities (e.g. root residues) cause changes in the microbial community structure due to specific and highly complex microbe-root-soil interactions. Site and system specific reactions of microorganisms towards rewetting, simulating the onset of rainy season, were observed. Higher respiration rates, higher amounts of microbial biomass carbon (Cmic) and nitrogen (Nmic) as well as higher ergosterol, muramic acid, glucosamine and adenylate concentrations were measured in CL soils of Koukombo and in both soils from Fada. The immediate increase in ATP concentrations after rewetting was likely caused by rehydration of microbial cells where N was not immobilized and, thus, available for plants facilitating their rapid development. Legume root residues led only to slightly better plant performances compared to the control, while the application of cereal roots reduced seedling growth. In contrast to sorghum seedlings, the microbial community did not react to the mineral treatment. Thus the energy supply in form of organic amendments increased microbial indices compared to mineral P application and the control. The results of basal respiration rates, Cmic and Corg levels indicate that the microbial community in the soil from Koukombo is less efficient in substrate use compared to microorganisms in the soil from Fada. However, the continuous carbon input by legume root residues might have contributed to these differences in soil fertility. With the 33P isotopic exchange method a low buffering capacity was detected in both soils irrespective of treatments. Calculated E values (E1min to E1min-1d and E1d-3m) indicated a slowly release of P due to root turnover while applied mineral P is taken up by plants or fixed to the soil. Due to the fact that sorghum growth reacted mainly to the application of mineral P and the microorganisms solely to the organic inputs, the combination of both amendments seems to be the best approach to a sustainable increase of crop production on many nutrient-poor, sandy West African soils. In a pot experiment, were CC and CL soils from Fada and Koukombo were adjusted to the same level of P and N concentrations, crop growth was significantly higher on CL soils, compared to the respective treatments on CC soils. Mycorrhizal infection of roots was increased and the number of nematodes, predominantly free living nematodes, was almost halfed on rotation soils. In conclusion, increased nutrient availability (especially P and N) through the introduction of legumes is not the only reason for the observed yield increasing effects. Soil biological factors seem to also play an important role. In a root chamber experiment the pH gradient along the root-soil-interface was measured at three times using an antimony microelectrode. For Fada soils, pH values were higher on CL than CC soils while the opposite was true for the Koukombo soils. Site-specific differences between Fada and Koukombo soils in N content and microbial community structures might have created varying crop performances leading to the contrasting pH findings. However, the mechanisms involved in this highly complex microbe-root-soil interaction remain unclear.

Symptoms and causes of poverty in a rural Vietnamese commune: Does ethnicity matter?

This study uses data from a sample survey of 200 households drawn from a mountainous commune in Vietnam’s North Central Coast region to measure and explain relative poverty. Principal components analysis is used to construct a multidimensional index of poverty outcomes from variables measuring household income and the value of domestic assets. This index of poverty is then regressed on likely causes of poverty including different forms of resource endowment and social exclusion defined by gender and ethnicity. The ordinary least squares estimates indicate that poverty is indeed influenced by ethnicity, partly through its interaction with social capital. However, poverty is most strongly affected by differences in human and social capital. Differences in the amount of livestock and high quality farmland owned also matter. Thai households are poorer than their Kinh counterparts even when endowed with the same levels of human, social, physical and natural capital considered in the study. This empirical result provides a rationale for further research on the causal relationship between ethnicity and poverty outcomes.

Causes and Effects of Chaos

Most of the recent literature on chaos and nonlinear dynamics is written either for popular science magazine readers or for advanced mathematicians. This paper gives a broad introduction to this interesting and rapidly growing field at a level that is between the two. The graphical and analytical tools used in the literature are explained and demonstrated, the rudiments of the current theory are outlined and that theory is discussed in the context of several examples: an electronic circuit, a chemical reaction and a system of satellites in the solar system.
