The Relationship Between State Effectiveness And State Legitimacy: A Quantitative Test

Legitimacy is a contested concept in political science. The question of legitimacy has been addressed in various topics, including state formation, state building, and state failure. This research is an attempt to quantitatively test the relationship between state legitimacy and state effectiveness and development in the economy, politics, and society. By examining the literature on legitimacy and its sources, the research tests the following hypothesis: a state with better performance in macro issues, including economic performance, social welfare, and political participation, is more likely to enjoy a higher level of legitimacy. In other words, this study attempts to establish a replicable formula for an incumbent state to achieve and sustain its legitimacy

Modélisation des suspensions de particules actives : application à la motilité séminale

Dans cette thèse, nous étudions le comportement collectif de particules auto-propulsées. Ce travail comporte trois parties. Dans la première partie, nous considérons un modèle individu-centré pour les particules d'auto rotation interagissant par une règle d'alignement et étudions leurs limites macroscopiques. Deux cas de sealing ont été étudiés. Dans le cas de petite vitesse angulaire, le modèle obtenu est une légère modification du modèle " Hydrodynamique auto-organisé " qui avait été introduit précédemment par Degond et Mostch. Dans le cas de grande vitesse angulaire, le modèle obtenu est plus compliqué. Une étude préliminaire de la stabilité linéaire a été également proposée. Dans la deuxième partie, nous étudions un modèle macroscopique du système de particules auto-propulsées interagissant avec leurs voisins par une règle d'alignement et de répulsion. Nous fournissons une validation numérique de ce modèle en le comparant avec le modèle individu centré. L'existence de solutions du modèle macroscopique à deux dimensions est prouvée. La dernière partie est consacrée à l'étude expérimentale du comportement collectif de robots auto-propulsés dans une enceinte annulaire confinée.In this thesis wc study collective motions of self-propelled particles. This work consists of three parts. In the first part, we consider an lndividual-Based Model for self-rotating particles interacting through local alignment and investigate its macroscopic Iimit. We study the mean-field kinetic and hydrodynamic limits of this system within two different scalings. In the small angular velocity regime, the resulting model is a slight modification of the " Self-Organised Hydrodynamic " model which has been previously inltroduced by Degond and Motsch. In the large angular velocity Case, the macroscopic model obtained is more complex. A preliminary study of the linearized stability is proposed. In the second part, we study a macroscopic model for a system of self-propelled particles which interact with their neighbors via alignment and repulsion. We provide a numerical validation of the continuum model by comparison with the particle model. The existence of local solutions of this macroscopic model is also studied. The last part concerns experimental investigation of collective behavior of simple robots in a confined ring

The influence of CEO characteristics on corporate environmental performance of SMEs: Evidence from Vietnamese SMEs

Drawing on upper echelon theory, this study investigates the impact of CEOs’ (chief executive officers) demographic characteristics on corporate environmental performance (CEP) in small and medium-sized enterprises (SMEs). We hypothesized that CEO characteristics, including gender, age, basic educational level, professional educational level, political connection, and ethnicity, affect SMEs’ environmental performance. Using the cross-sectional data analysis of 810 Vietnamese SMEs, this study provides evidence that female CEOs and CEOs’ educational level (both basic and professional) are positively related to the probability of CEP. We also find that based on the role of institutional environment on CEP, political connections had a negative effect on CEP in the context of Vietnam. Another finding is that SMEs with chief executives from ethnic minority groups show a higher level of the probability of corporate environmental performance than companies operated by Kinh chief executives. Since CEP is an essential dimension of corporate social responsibility, a strategic decision for SMEs, it is crucial for the company to select appropriate CEOs based on their demographic characteristic

Improving Gifted and Talented Education in Arkansas: Identification, Academic Benefits, and Local Norms

In the United States, education policies differ from state to state. Local research, therefore, is important to inform educators, policymakers, and researchers on the ground. This dissertation leverages ten years of administrative data to study three questions about gifted and talented (G/T) identification and education in Arkansas: does the current system identify the right students? Are gifted and talented programs beneficial for students? And, how can we improve diversity in gifted and talented education? Leveraging logistic regression, mixed-effects models, and descriptive statistics, I sought to provide answers to these three questions. First, are academically ready students from low-income families being missed in the current gifted and talented education system? Second, do gifted and talented services benefit high aptitude students academically? And finally, does using the local norm approach necessarily improve diversity in the G/T pool of students? This study has important implications for Arkansas’s G/T identification and education policies

Predicting Information Diffusion on Twitter - Analysis of predictive features

Information propagation on online social network focuses much attention in various domains as varied as politics, fact checking, or marketing. Modeling information diffusion in such growing communication media is crucial in order both to understand information propagation and to better control it. Our research aims at predicting whether a post is going to be forwarded or not. Moreover, we aim at predicting how much it is going to be diffused. Our model is based on three types of features: user-based, time-based and content-based. Using three collections corresponding to a total of about 16 millions of tweets, we show that our model improves of about 5% F-measure compared to the state of the art, both when predicting if a tweet is going to be re-tweeted and when predicting how popular it will be. F-measure in our model is between 70% and 82%, depending on the collection. We also show that some features we introduced are very important to predict retweetability such as the numbers of followers and number of communities that a user belongs to. Our contribution in this paper is twofold: firstly we defined new features to represent tweets in order to predict their possible propagation; secondly we evaluate the model we built on top of both features from the literature and features we defined on three collections and show the usefulness of our features in the prediction

VIETNAM'S ELECTRONICS INDUSTRY: THE RISE AND PROBLEMS OF FURTHER DEVELOPMENT

Purpose: To evaluate the Vietnamese electronics industry (EI) by analyzing its successes and shortcomings in recent years in comparison with other Southeast Asian countries, as well as the problems faced by the young industries in Vietnam in the course of its development and identify their abilities to participate in the global value chain. Methodology: Systems approach was used to analyze the status of Vietnam’s EI. The advantages and the results achieved by EI are assessed and described with the help of objective data from statistical and officially published sources. Main Findings: The position of Vietnam’s EI in the context of growing industry 4.0 was recognized. Its dependence on imports and other reasons that affect its efficiency and competitiveness were identified in the study. The Government should provide adequate support for the development of priority area including EI within the framework of national policies and encourage import substitution program of the industrial enterprises.

Content and language integrated learning in Vietnam: evolution of students' and teachers' perceptions in an innovative foreign language learning system

Cette recherche porte sur un dispositif d'enseignement d'une langue étrangère innovant au Vietnam, de type EMILE (Enseignement d'une matière intégrée à une langue étrangère) et promu par Le Ministère de l'éducation et de la formation en 2008. IL s'agit d'une recherche exploratoire et qualitative visant à extraire les représentations d'élèves de 1ère et 2ème année au lycée. Un premier questionnaire administré au début de la mise en œuvre de l'EMILE porte sur leurs perceptions/motivations au sujet de l'anglais en général, les cours d'anglais et les cours de type EMILE. Un deuxième questionnaire a été administré après une année et demi de pratique de l'EMILE. Parallèlement, les enseignants de spécialité qui participaient au dispositif EMILE, ont été interviewés. Le traitement des données a permis de confronter les perceptions des élèves et des enseignants à propos du dispositif innovant et d'en identifier les qualités et les défauts. Les résultats soulignent le décalage qui existe entre la perception des potentialités du dispositif et les nombreux obstacles concrets qui entravent leurs réalisations.The present research examines Content and Language Integrated Learning (CLIL), an innovative language learning system in Vietnam launched by the Vietnamese Ministry of Education and Training in 2008. This exploratory, qualitative investigation was first centred on the perceptions of high school students, obtained through two questionnaires. The first one was administered at the outset of the CLIL implementation, with a view to identifying their perceptions about and motivations for English in general, English as a Foreign Language and CLIL. A second questionnaire was administered after a year and a half of CLIL practice to evaluate potential motivational changes. At the same time, the content teachers of the project who taught their speciality in English were interviewed. Data processing made it possible to cross-check students' and teachers' perceptions of CLIL, its assets and its drawbacks. The results point out the discrepancy which exists between the perceived didactic potentialities of CLIL and the many concrete impediments that hamper their full realization. In the wake of this survey, some recommendations are made to improve CLIL implementation in Vietnam, particularly with regard to the content teachers' training in the foreign language

Types of momentum defect diffusion at the begining of the wake and wake establishment zone for the coupled wake and comparison with the isolated wake

The article [10] has presented the necessity of the classification into two types: Isolated wakes and coupled wakes. In this report, different types of momentum defect diffusion at the beginning of wake are analyzed for the two types of coupled wake and isolated wake. According to ·numerical results obtained, we analyses the existence - long or short - of the wake establishment zone before the wake established zone, and this zone is very different between isolated wake and coupled wake
