    Analysis of multinomial counts with joint zero-inflation, with an application to health economics

    No full text
    International audienceZero-inated regression models for count data are often used in health economics to analyse demand for medical care. Indeed, excess of zeros often aects health-care utilization data. Much of the recent econometric literature on the topic has focused on univariate health-care utilization measures, such as the number of doctor visits. However, health service utilization is usually measured by a number of dierent counts (e.g., numbers of visits to dierent health-care providers). In this case, zero-ination may jointly aect several of the utilization measures. In this paper, a zero-inated regression model for multinomial counts with joint zero-ination is proposed. Maximum likelihood estimators in this model are constructed and their properties are investigated, both theoretically and numerically. We apply the proposed model to an analysis of health-care utilization

    Mobixim: A Framework for Devising Collaborative Algorithms

    Get PDF
    Indoor Tracking Systems (ITS) are becoming increasingly popular due to their affordability and the services they provide, such as indoor navigation and asset tracking. Most of the ITS presented in the literature or deployed in the real world rely on dedicated infrastructures that are costly and difficult to deploy and maintain. An alternative lies in infrastructure-free ITS based on inertial sensors embedded in each mobile device, but such ITS suffer from an accumulation of errors degrading their accuracy. To mitigate this accuracy degradation, an approach consists in fostering collaboration between moving devices. However, a major limitation of this approach lies in the complexity of devising such collaborative inertial-based algorithms. In this paper, we address this limitation by proposing MobiXIM, a framework that unifies the processes of devising, evaluating, and fine-tuning collaborative inertial-based algorithms. In addition, we propose a midpoint algorithm devised using our proposed framework. Through this experiment, we highlight each of the components of MobiXIM that operate separately and communicate with each other, thus allowing researchers to focus solely on developing specific parts of their solutions

    An insight of combustibility induced safety issues pertaining to ionic liquids

    Get PDF
    International audienceThis study is a consolidated overview on explosion and fire safety issues pertaining to ionic liquids. Indeed safety performance of ionic liquids relating to physico-chemical hazards is very rarely investigated as it is often perceived as a non-existing issue due to the lack of traditional flashpoint for these liquids. It focuses on the experimental evaluation of the fire hazard of imidazolium, phosphonium and pyrrolidinium-based ionic liquids by use of the Fire Propagation Apparatus. It provides experimental data that can quantify the flammability of ionic liquids in all its aspects (ease of ignition, mass burning rate, heat release rate, fire-induced toxicity data...). A case study featuring a major failure in a process unit leading to a given fire scenario is also illustrated. This case study is examined in terms of fire induced toxicity by use of CFD modeling of fire product releases dispersion and using the concept of fractional effective concentration

    Esta dissertação baseia-se numa panóplia de estudos, desenvolvidos com base na investigação e experimentação. É uma síntese de aprendizagem de todo um percurso letivo, resumido e condensado num só ano de tese. Este estudo começa então com um olhar mais profundo sobre casas projetadas em Portugal, e com autoria de arquitetos portugueses. Durante semanas, a turma conseguiu reunir mais de 180 projetos nacionais, os quais foram analisados e discutidos ao longo das aulas. Numa segunda fase, foi atribuído um tema por aluno, a ser desenvolvido em curadoria, e relacionado com as 180 casas. Por fim, numa última fase, cada aluno era convidado a desenhar a sua própria casa. Portanto, uma jornada relativamente exaustiva, através da qual se foram debruçando caminhos diversos de exploração. O resultado culmina numa demonstração de um discurso arquitetónico, realizado com ferramentas de registo e de desenho, adquiridas ao longo de 5 anos de curso e, com base na observação, análise e experimentação.This dissertation is based on a panoply of studies, developed on the basis of research and experimentation. It is a synthesis of learning of an entire academic path, summarized and condensed in a single year of thesis. This study starts then with a deeper look at houses designed in Portugal, and with authorship of Portuguese architects. During weeks, the class managed to gather more than 180 national projects, which were analysed and discussed throughout the classes. In a second phase, a theme was assigned per student, to be developed in curatorship, and related to the 180 houses. Finally, in a last phase, each student was invited to design their own house. Therefore, a relatively exhaustive journey, through which diverse paths of exploration were taken. The result culminates in a demonstration of an architectural discourse, carried out with tools of registration and drawing, acquired over 5 years of study, and based on observation, analysis and experimentation

    Usutu virus (USUV) was discovered in South Africa in 1959. Since then, it has been reported in several African countries including Senegal, Central African Republic, Nigeria, Uganda, Burkina Faso, Cote d'Ivoire, and Morocco. In 2001, USUV has been identified for the first time outside of Africa, namely in Europe, where it caused a significant mortality among blackbirds in Vienna, Austria. In 2009, the first two human cases of USUV infection in Europe have been reported in Italy, causing encephalitis in immunocompromised patients. The host range in Africa includes mainly Culex mosquitoes, birds, and also humans with one benign and one severe case. Given its role as a potential human pathogen and the similar appearance compared with other emerging arboviruses, it is essential to investigate the natural history and ecology of USUV in Africa. In this regard, we review the emergence of USUV in Africa, summarizing data about isolations, host range, and potential vectors, which should help to improve our understanding of the factors underlying the circulation of USUV in Europe and Africa

    Vector competence of Aedes vexans (Meigen), Culex poicilipes (Theobald) and Cx. quinquefasciatus Say from Senegal for West and East African lineages of Rift Valley fever virus

    Background Rift Valley fever virus (RVFV; Phlebovirus, Bunyaviridae) is a mosquito–borne, zoonotic pathogen. In Senegal, RVFV was first isolated in 1974 from Aedes dalzieli (Theobald) and thereafter from Ae. fowleri (de Charmoy), Ae. ochraceus Theobald, Ae. vexans (Meigen), Culex poicilipes (Theobald), Mansonia africana (Theobald) and Ma. uniformis (Theobald). However, the vector competence of these local species has never been demonstrated making hypothetical the transmission cycle proposed for West Africa based on serological data and mosquito isolates. Methods Aedes vexans and Cx. poicilipes, two common mosquito species most frequently associated with RVFV in Senegal, and Cx. quinquefasciatus, the most common domestic species, were assessed after oral feeding with three RVFV strains of the West and East/central African lineages. Fully engorged mosquitoes (420 Ae. vexans, 563 Cx. quinquefasciatus and 380 Cx. poicilipes) were maintained at 27 ± 1 °C and 70–80 % relative humidity. The saliva, legs/wings and bodies were tested individually for the RVFV genome using real-time RT-PCR at 5, 10, 15 and 20 days post exposure (dpe) to estimate the infection, dissemination, and transmission rates. Genotypic characterisation of the 3 strains used were performed to identify factors underlying the different patterns of transmission. Results The infection rates varied between 30.0–85.0 % for Ae. vexans, 3.3–27 % for Cx. quinquefasciatus and 8.3–46.7 % for Cx. poicilipes, and the dissemination rates varied between 10.5–37 % for Ae. vexans, 9.5–28.6 % for Cx. quinquefasciatus and 3.0–40.9 % for Cx. poicilipes. However only the East African lineage was transmitted, with transmission rates varying between 13.3–33.3 % in Ae. vexans, 50 % in Cx. quinquefasciatus and 11.1 % in Cx. poicilipes. Culex mosquitoes were less susceptible to infection than Ae. vexans. Compared to other strains, amino acid variation in the NSs M segment proteins of the East African RVFV lineage human-derived strain SH172805, might explain the differences in transmission potential. Conclusion Our findings revealed that all the species tested were competent for RVFV with a significant more important role of Ae. vexans compared to Culex species and a highest potential of the East African lineage to be transmitted
