Empresas promotoras de saúde no sistema de saúde colombiano: dinâmica financeira estrutural. / Health promothing entity in the colombian health system: structural financial dynamics.

Javier David Rodríguez Ruiz 06 April 2015 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Esta dissertação analisou as Empresas Promotoras de Salud (EPS), seguradoras de saúde introduzidas no sistema de saúde colombiano através da reforma sanitária instaurada com a Lei n 100/1993, desde uma perspectiva de economia política crítica, através do método de análise documental. A maioria delas são empresas privadas com finalidade lucrativa que conformaram rapidamente um oligopólio que reproduziu problemas dos modelos de Managed Care e Managed Competition já conhecidos internacionalmente. Esta dissertação analisou as relações entre os processos de financeirização do sistema capitalista e o processo de ajuste estrutural na Colômbia, com a reforma sanitária e a dinâmica financeira das EPS. Também foi analisada a introdução de mecanismos próprios do processo de financeirização na gestão financeira das EPS, como: a alavancagem; a reprodução ampliada de capital através da dívida pública; e os investimentos em ativos securitizados. Dado que o sistema de saúde atual se caracteriza por altos níveis de inequidade e injustiça, as consequências da finalidade lucrativa neste, com suas expressões concretas de sofrimento e morte na população, foram preocupações transversais deste trabalho. Os resultados desta dissertação demonstraram a concentração oligopólica do mercado de seguros privados de saúde, cujas empresas se organizaram como um cartel, dificultando o acesso aos serviços de saúde para seus segurados, o que contribuiu para a piora de indicadores de saúde da população. Quando a mobilização social obrigou a aumentar o controle sobre as EPS, estas começaram a sair do mercado declarando-se em falência, ou entrando subitamente em balanços financeiros negativos. / This thesis analyzes the Empresas Promotoras de Salud (EPS meaning health promoting entity), which are health insurance companies that act in the Colombian health system since the health reform law of 1993 (Law 100). Based on a document analysis and within a critical political economy framework, we firstly address the relations between the financialization process in the capitalist system, the structural reforms and the health care reform, with the EPSs financial dynamics, and secondly address the reproduction of financialization mechanism inside the EPS including financial leverage; expanded reproduction of capital through the public debt; and investments in securitized assets. Most EPS are private for profit companies, which quickly formed an oligopolistic market and exemplify internationally recognized contradictions of the Managed Care and Managed Competition models, also as its forprofit orientation and functioning has been related to the exacerbation of health inequities and has further been recognized as a driver of suffering and death in the population. This has primarily been related to the oligopolistic concentration of the private health insurance market, whose companies are organized as a cartel, hindering access to health services for the population. When social mobilization forced to increase control over the EPS, they began to leave the market declaring themselves bankrupt, or suddenly entered negative financial statements.

A Theoretical Framework To Measure Diffusion In Intermediary B2B Market : A Case Of Electronic Payment Systems (EPS)

Pratheeba, S 01 1900 (has links) (PDF)
Electronic Payment Systems (EPS) are gaining popularity all over the world. An EPS consists of many component technologies which facilitate cashless payments for services. The focus of this thesis is on device associated technologies that an end customer uses to initiate an e-payment for a particular service via a Payment Service Provider (PSP). A technology solution in an EPS is developed by a Payment Solution Developer (PSD). The market between a PSP and a PSD is a B2B market. A PSD must understand and develop that combination of technology and service which will successfully diffuse. The success of a PSP therefore depends a lot on what a PSD develops. A theoretical framework to measure diffusion of e-payment technologies, services and their combinations in the B2B market was developed and empirically assessed in this thesis. Two concepts namely concept of breadth and concept of spread were defined. The concept of breadth and spread were applied to e-payment technologies, services and their combinations. The derived concepts namely technology breadth, service breadth, technology spread, service spread and technology-service combination spread were defined and measured. We then extended the concept of breadth to understand utilization of technologies and services within an EPS. Set theory was used to describe the framework. A sample of 45 EPS was compiled from various sources. This secondary data of EPS consisted of 8 technologies and 16 services. The 8 technologies are Interactive Voice Response (IVR), text messaging using Short Messaging Service (SMS), text messaging using Unstructured Supplementary Service Data (USSD), mobile internet using Wireless Application Protocol (WAP), mobile application, Near Field Communication (NFC), Personal Computer (PC) internet and smart card. The 16 services are retail shopping payment, banking, health payment, insurance payment, mobile bill payment, mobile recharge, money transfer, movie ticket booking, parking fee payment, restaurant payment, payment at sports/swimming club, toll payment, transportation payment, tuition fee payment, utilities payment, and vending machine payment. Three categories of PSPs namely core payment service providers (n=18), non-core payment service providers (n=12) and merchants (n=15) were identified from the 45 EPS. Binomial proportion test was used to verify the concepts of breadth and spread. Spearman correlation was used to find correlation between the concept of breadth and spread of technologies and services. The 45 EPS in the sample were then grouped under three sub groups based on the categories of their PSPs. Binomial tests were used within each sub group to understand the preferences of technologies, services and their combinations by each category. The results verified that certain e-payment technologies possess more breadth i.e., capability to deliver many e-payment services and certain e-payment services possess more breadth i.e., delivered by many e-payment technologies. A difference in diffusion i.e., spread of technologies, services and their combinations were observed. Details of these differences are discussed in this thesis for technologies, services and their combinations. A positive correlation was observed between the concept of breadth and spread. Specialization of technologies, services and their combinations within categories of PSPs were observed. Variations in utilization of technologies and services by EPS were observed.

Statistical Post-Processing Methods And Their Implementation On The Ensemble Prediction Systems For Forecasting Temperature In The Use Of The French Electric Consumption / Les propriétés statistiques de correction des prévisions de température et leur application au système des prévisions d’ensemble (SPE) de Météo France

Gogonel, Adriana Geanina 27 November 2012 (has links)
L’objectif des travaux de la thèse est d’étudier les propriétés statistiques de correction des prévisionsde température et de les appliquer au système des prévisions d’ensemble (SPE) de MétéoFrance. Ce SPE est utilisé dans la gestion du système électrique, à EDF R&D, il contient 51membres (prévisions par pas de temps) et fournit des prévisions à 14 jours. La thèse comportetrois parties. Dans la première partie on présente les SPE, dont le principe est de faire tournerplusieurs scénarios du même modèle avec des données d’entrée légèrement différentes pour simulerl’incertitude. On propose après des méthodes statistiques (la méthode du meilleur membre etla méthode bayésienne) que l’on implémente pour améliorer la précision ou la fiabilité du SPEdont nous disposons et nous mettons en place des critères de comparaison des résultats. Dansla deuxième partie nous présentons la théorie des valeurs extrêmes et les modèles de mélange etnous proposons des modèles de mélange contenant le modèle présenté dans la première partieet des fonctions de distributions des extrêmes. Dans la troisième partie nous introduisons larégression quantile pour mieux estimer les queues de distribution. / The thesis has for objective to study new statistical methods to correct temperature predictionsthat may be implemented on the ensemble prediction system (EPS) of Meteo France so toimprove its use for the electric system management, at EDF France. The EPS of Meteo Francewe are working on contains 51 members (forecasts by time-step) and gives the temperaturepredictions for 14 days. The thesis contains three parts: in the first one we present the EPSand we implement two statistical methods improving the accuracy or the spread of the EPS andwe introduce criteria for comparing results. In the second part we introduce the extreme valuetheory and the mixture models we use to combine the model we build in the first part withmodels for fitting the distributions tails. In the third part we introduce the quantile regressionas another way of studying the tails of the distribution.

From locomotion to dance and back : exploring rhythmic sensorimotor synchronization

Chemin, Baptiste 09 1900 (has links)
Le rythme est un aspect important du mouvement et de la perception de l’environnement. Lorsque l’on danse, la pulsation musicale induit une activité neurale oscillatoire qui permet au système nerveux d’anticiper les évènements musicaux à venir. Le système moteur peut alors s’y synchroniser. Cette thèse développe de nouvelles techniques d’investigation des rythmes neuraux non strictement périodiques, tels que ceux qui régulent le tempo naturellement variable de la marche ou la perception rythmes musicaux. Elle étudie des réponses neurales reflétant la discordance entre ce que le système nerveux anticipe et ce qu’il perçoit, et qui sont nécessaire pour adapter la synchronisation de mouvements à un environnement variable. Elle montre aussi comment l’activité neurale évoquée par un rythme musical complexe est renforcée par les mouvements qui y sont synchronisés. Enfin, elle s’intéresse à ces rythmes neuraux chez des patients ayant des troubles de la marche ou de la conscience. / Rhythms are central in human behaviours spanning from locomotion to music performance. In dance, self-sustaining and dynamically adapting neural oscillations entrain to the regular auditory inputs that is the musical beat. This entrainment leads to anticipation of forthcoming sensory events, which in turn allows synchronization of movements to the perceived environment. This dissertation develops novel technical approaches to investigate neural rhythms that are not strictly periodic, such as naturally tempo-varying locomotion movements and rhythms of music. It studies neural responses reflecting the discordance between what the nervous system anticipates and the actual timing of events, and that are critical for synchronizing movements to a changing environment. It also shows how the neural activity elicited by a musical rhythm is shaped by how we move. Finally, it investigates such neural rhythms in patient with gait or consciousness disorders.

現金流量與相關會計變數對於股價報酬率關連性之研究 / The Relationship Between Free Cash Flow, Related Accounting Variable and Stock Returns

許欣欣, Shue, Sing-Sing Unknown Date (has links)
本研究試圖瞭解投資人所關心的財務資訊,是否真能帶來超額報酬,亦即探討上市公司股票報酬率與各財務資訊之間的關係,包括每股盈餘成長率及益本比、市價淨值比、自由現金流量相關變數對長期股票報酬之影響,並嘗試對各變數給予經濟上的解釋。   其中並試圖找出財務資訊究竟是在何時反應於股票報酬與超額報酬上,因此將股票報酬與超額報酬以領先財務資訊一季、與財務資訊同季及落後財務資訊一季等三個時點加以衡量,並以表面無關迴歸模式(Seemingly Unrelated Regression model ; SUR)與混合橫斷面及縱斷面之迴歸模式進行統計分析。   結果發現益本比及每股盈餘成長率與股票報酬及超額報酬的關係並不顯著;市價淨值比與落後一季的股價報酬具有顯著的負相關,而與超額報酬不論衡量時點為何均存在有顯著正相關;自由現金流量與股價報酬及額報酬均無顯著關係;毛現金流量與經濟利益率與股價報酬在部分產業中具有顯著關係,而與當期超額股價報酬則存在顯著的關係,惟影響符號不一致。此外各自變數對於股票超額報酬的關連性較自變數與股票報酬間具有較顯著的關係。

Application of the Stimulus-Driven Theory of Probabilistic Dynamics to the hydrogen issue in level-2 PSA. Application de la Stimulus Driven Theory of Probabilistic Dynamics (SDTPD) au risque hydrogène dans les EPS de niveau 2.

Peeters, Agnès 05 October 2007 (has links)
Les Etudes Probabilistes de Sûreté (EPS) de niveau 2 en centrale nucléaire visent à identifier les séquences d’événements pouvant correspondre à la propagation d’un accident d’un endommagement du cœur jusqu’à une perte potentielle de l’intégrité de l’enceinte, et à estimer la fréquence d’apparition des différents scénarios possibles. Ces accidents sévères dépendent non seulement de défaillances matérielles ou d’erreurs humaines, mais également de l’occurrence de phénomènes physiques, tels que des explosions vapeur ou hydrogène. La prise en compte de tels phénomènes dans le cadre booléen des arbres d’événements s’avère difficile, et les méthodologies dynamiques de réalisation des EPS sont censées fournir une manière plus cohérente d’intégrer l’évolution du processus physique dans les changements de configuration discrète de la centrale au long d’un transitoire accidentel. Cette thèse décrit l’application d’une des plus récentes approches dynamiques des EPS – la Théorie de la Dynamique Probabiliste basée sur les Stimuli (SDTPD) – à différents modèles de déflagration d'hydrogène ainsi que les développements qui ont permis cette applications et les diverses améliorations et techniques qui ont été mises en oeuvre. Level-2 Probabilistic Safety Analyses (PSA) of nuclear power plants aims to identify the possible sequences of events corresponding to an accident propagation from a core damage to a potential loss of integrity of the containment, and to assess the frequency of occurrence of the different scenarios. These so-called severe accidents depend not only on hardware failures and human errors, but also on the occurrence of physical phenomena such as e.g. steam or hydrogen explosions. Handling these phenomena in the classical Boolean framework of event trees is not convenient, and dynamic methodologies to perform PSA studies are expected to provide a more consistent way of integrating the physical process evolution with the discrete changes of plant configuration along an accidental transient. This PhD Thesis presents the application of one of the most recently proposed dynamic PSA methodologies, i.e. the Stimulus-Driven Theory of Probabilistic Dynamics (SDTPD), to several models of hydrogen explosion in the containment of a plant, as well as the developed methods and improvements.

4G LTE : eMBMS with MBSFN Service Simulation using OPNET

Walid, Abdelrahman January 2014 (has links)
Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. 3Th Generation Partnership Project (3GPP) specialized that LTE released 10 and beyond known as LTE-advanced it is the second evolution of LTE. It has some services such as Coordinated Multipoint Transmission and Reception (CoMP), evolved Multimedia Broadcast and Multicast Service (eMBMS) with Multicast-Broadcast Single-Frequency Network (MBSFN). The development still continuous on LTE-advanced, it is intended to meet the requirement of advanced application that will become common in the wireless marketplace in future. The goals of this project is to simulate one of LTE-A services on LTE standard such as CoMP or/and eMBMS with MBSFN using OPENT LTE, and measure some statistic such as spectral efficiency and also some other statistics, describe centralization vs. decentralization in LTE, and synchronization in the base station in LTE. OPNET LTE support eMBMS with MBSFN, and don’t support CoMP, the simulation has been done by using eMBMS with MBSFN. Finally the objectives of the project has achieved, the result show that when eMBMS with MBSFN is implemented the throughput increased in the downlink to about 5.52 Mbps and in the uplink to about 5.18 Mbps, and also the system spectral efficiency increased in eNB1 from about 10.25 (bits/s/Hz/cell) to about 13.75 (bits/s/Hz/cell) and in eNB2 from about 10.25 (bits/s/Hz/cell) to about 17.25 (bits/s/Hz/cell). The project also answers if it is possible to have centralization in LTE, describe synchronization in the base station in LTE, and if OPNET is useful for big research.
