What matters for predicting spatial distributions of trees: techniques, data, or species' characteristics?

Data characteristics and species traits are expected to influence the accuracy with which species' distributions can be modeled and predicted. We compare 10 modeling techniques in terms of predictive power and sensitivity to location error, change in map resolution, and sample size, and assess whether some species traits can explain variation in model performance. We focused on 30 native tree species in Switzerland and used presence-only data to model current distribution, which we evaluated against independent presence-absence data. While there are important differences between the predictive performance of modeling methods, the variance in model performance is greater among species than among techniques. Within the range of data perturbations in this study, some extrinsic parameters of data affect model performance more than others: location error and sample size reduced performance of many techniques, whereas grain had little effect on most techniques. No technique can rescue species that are difficult to predict. The predictive power of species-distribution models can partly be predicted from a series of species characteristics and traits based on growth rate, elevational distribution range, and maximum elevation. Slow-growing species or species with narrow and specialized niches tend to be better modeled. The Swiss presence-only tree data produce models that are reliable enough to be useful in planning and management applications.

Computational analysis of the genetic and environmental contributions to disease-related human phenotypes: From predicting adverse lipid response of HIV patients receiving antiretroviral therapy to genome-wide association studies of cardiovascular and lipid related disorders

Genetic variants influence the risk to develop certain diseases or give rise to differences in drug response. Recent progresses in cost-effective, high-throughput genome-wide techniques, such as microarrays measuring Single Nucleotide Polymorphisms (SNPs), have facilitated genotyping of large clinical and population cohorts. Combining the massive genotypic data with measurements of phenotypic traits allows for the determination of genetic differences that explain, at least in part, the phenotypic variations within a population. So far, models combining the most significant variants can only explain a small fraction of the variance, indicating the limitations of current models. In particular, researchers have only begun to address the possibility of interactions between genotypes and the environment. Elucidating the contributions of such interactions is a difficult task because of the large number of genetic as well as possible environmental factors.In this thesis, I worked on several projects within this context. My first and main project was the identification of possible SNP-environment interactions, where the phenotypes were serum lipid levels of patients from the Swiss HIV Cohort Study (SHCS) treated with antiretroviral therapy. Here the genotypes consisted of a limited set of SNPs in candidate genes relevant for lipid transport and metabolism. The environmental variables were the specific combinations of drugs given to each patient over the treatment period. My work explored bioinformatic and statistical approaches to relate patients' lipid responses to these SNPs, drugs and, importantly, their interactions. The goal of this project was to improve our understanding and to explore the possibility of predicting dyslipidemia, a well-known adverse drug reaction of antiretroviral therapy. Specifically, I quantified how much of the variance in lipid profiles could be explained by the host genetic variants, the administered drugs and SNP-drug interactions and assessed the predictive power of these features on lipid responses. Using cross-validation stratified by patients, we could not validate our hypothesis that models that select a subset of SNP-drug interactions in a principled way have better predictive power than the control models using "random" subsets. Nevertheless, all models tested containing SNP and/or drug terms, exhibited significant predictive power (as compared to a random predictor) and explained a sizable proportion of variance, in the patient stratified cross-validation context. Importantly, the model containing stepwise selected SNP terms showed higher capacity to predict triglyceride levels than a model containing randomly selected SNPs. Dyslipidemia is a complex trait for which many factors remain to be discovered, thus missing from the data, and possibly explaining the limitations of our analysis. In particular, the interactions of drugs with SNPs selected from the set of candidate genes likely have small effect sizes which we were unable to detect in a sample of the present size (<800 patients).In the second part of my thesis, I performed genome-wide association studies within the Cohorte Lausannoise (CoLaus). I have been involved in several international projects to identify SNPs that are associated with various traits, such as serum calcium, body mass index, two-hour glucose levels, as well as metabolic syndrome and its components. These phenotypes are all related to major human health issues, such as cardiovascular disease. I applied statistical methods to detect new variants associated with these phenotypes, contributing to the identification of new genetic loci that may lead to new insights into the genetic basis of these traits. This kind of research will lead to a better understanding of the mechanisms underlying these pathologies, a better evaluation of disease risk, the identification of new therapeutic leads and may ultimately lead to the realization of "personalized" medicine.

La Costa Brava ante los nuevos retos del turismo

The first section of this paper summarises the most relevant charateristics of the contemporary tourist model, also called postfordist or postmodernist. In the second part the traditional tourist model developed in the Costa Brava in the past decades, is reviewed. Emphasising the saturation of tourist facilities on the coast line, expansive urban growth, thanks to a tolerant administration, poor complementary supply and concentrated demand in few markets and the proximity of Barcelona conurbation, stressed by second homes. In the third section, some strategies developed in recent years to readapt the Costa Brava to the new tendencies in tourism, are presented. Incorporation of the inland to the tourist product, new planning policics, lessening urban densities and height, and a change in mind in favour of protected natural areas, diversification of demand with new markets, specially form Eastern Europe (although this might be considered as a continuation ofthe traditional tourist model) and the emergence of local strategies oriented towards the creation of new tourist products based upon natural and cultural resources

De los Austrias a los Borbones en la historia general de Modesto Lafuente

Modesto Lafuente fue el autor de la Historia General de España , una obra que puede considerarse como paradigmática de las historias nacionales que surgieron en Europa a en el siglo XIX. Además de ser un hombre de letras muy reconocido y de contribuir a la profesionalización de la historiografía española, Lafuente fue diputado hasta su muerte en 1866. Su historiografía ligaba pasado y presente para construir una identidad nacional. Con ella buscaba dar una legitimidad al nuevo proyecto social que se iniciaba a partir del reinado de Isabel II. Los capítulos dedicados a la transición de los Austrias a los Borbones, en los que se abordan temas como el reinado de Carlos II, la guerra de Sucesión o las reformas de Felipe V, pueden interpretarse como una lectura romántica, teleológica y presentista. En definitiva, su narración del pasado histórico contribuyó a formar una memoria oficial, y por tanto debe considerarse una pieza clave para la identidad del nuevo Estado- nación español.

“Entretejiendo encajes” entre la universidad, los centros de arte y las escuelas

Habitualmente la formación inicial de profesionales de la educación suele realizarse en los contextos universitarios, las escuelas son consideradas contextos para realizar las prácticas y los museos y centros de arte tienen poca presencia en la formación de maestros. Por ello desde la Facultad de Ciencias de la Educación de la UdL y en el contexto de la formación inicial de maestros y psicopedagogos empezamos a entretejer la red entre la Facultad, los centros educativos y los recursos culturales comunitarios para mejorar la formación de todas las personas implicadas. Concretamente, estamos desarrolando el espacio híbrido en el marco del proyecto Educ-arte dando especial énfasis a las relaciones creadas entre la Facultad de Ciencias de la Educación, el Centro de Arte la Panera y la escuela Príncep de Viana de Lleida. Para ello utilizamos el arte contemporáneo como mediador de aprendizajes y como instrumento de formación y construcción de conocimientos. Nuestra aportación está enmarcada en los planteamientos socioconstructivistas que sitúan la cultura como elemento básico para la humanización de las personas. Es por ello que en nuestro entretejer situamos los recursos comunitarios culturales en general y museos y centros de arte en particular como parte esencial del trabajo en red.

Ydinvoimalaitoksen turbiinilaitoksen toiminnan ja kunnonvalvonnan nykytilan kuvaus ja kehittämismahdollisuuksien kartoitus sekä toteutus ja kannattavuusarviointi

Työssä selvitettiin Olkiluodon ydinvoimalaitoksen prosessiseurannassa nykyisin käytössä olevia järjestelmiä sekä tutkittiin prosessisimulointiohjelman käyttömahdollisuuksia osana prosessiseurantaa. Ensisijaisesti tutkittiin kuinka hyvin simulointimalli soveltuu pienien tehopoikkeamien havainnoimiseen. Simulointimalli rakennettiin Endat Oy:n kehittämällä Prosim-simulointiohjelmalla. Simulointimalli on tehty kahdelle eri prosessille. Erilliset mallit rakennettiin sekä vuoden 2003 vuosihuoltoa edeltäneelle prosessille, että vuosihuollossa lauhteen esilämmityksen osalta muutetulle prosessille. Simulointimallien toimintaa käytännössä testattiin suorittamalla simulointiajoja muutamilla prosessin muutostilanteilla ja vertailemalla muutostilanteiden mittapistedataa simulointiohjelman laskemiin tuloksiin. Simulointimallin suurimmat poikkeamat mittapistedataan verrattuna todettiin turbiinilaitoksen korkeapainepuolella sekä lauhduttimessa. Käytännössä havaittiin, että nämä poikkeamat hankaloittavat simulointiohjelman käyttöä käytönvalvonnan työkaluna, eikä sen käytöstä näin ollen saada varsinaista lisäarvoa.

"Ici la Suisse-Do isch t Schwyz-Switzerland calling!" : la société suisse de radiodiffusion (SSR) au service du rayonnement culturel helvetique (1932-1949)

La dialectique entre radiodiffusion et histoire des relations culturelles internationales est un domaine largement inexploré. L'objectif de cette thèse est d'analyser le rôle de la Société suisse de radiodiffusion (SSR), société privée qui exerce jusqu'en 1983 le monopole sur l'ensemble des stations de radio suisses, dans l'intensification des relations culturelles internationales de la Confédération. Pour examiner cette dimension des activités de la SSR, je me suis prioritairement penchée sur l'étude de la radio internationale helvétique, dénommée alors « Service suisse d'ondes courtes » (SOC). A l'instar de plusieurs organismes similaires à l'étranger, le SOC remplit dès ses débuts une double mission : resserrer les liens avec la diaspora et faire rayonner le pays hors des frontières nationales. Cette recherche met sur le devant de la scène un acteur médiatique aujourd'hui totalement oublié, le Service suisse d'ondes courtes. Par rapport à l'historiographie des radios internationales, elle mêle approche institutionnelle et, dans la mesure des sources disponibles, l'analyse de la programmation. Elle complète aussi l'histoire de la diplomatie culturelle suisse en rappelant la place du service public audiovisuel parmi les institutions chargées de promouvoir le pays à l'étranger. Pour finir, cette étude constitue également un apport à l'histoire des organisations internationales liées à la radiodiffusion (UIR, UIT). L'analyse du volet international des activités de la SSR a permis de dépasser la seule notion de « puissance » qui a été jusqu'à ces dernières années au coeur des ouvrages dévolus aux radios internationales. L'objectif poursuivi par la SSR ne réside pas tellement dans la diplomatie d'influence (l'exercice d'un « soft power »), qui tend à imposer ses valeurs et un mode de vie, mais plutôt dans la volonté de faire comprendre et reconnaître la culture politique de la Suisse dans le but de renforcer et pérenniser la place de celle-ci dans le concert des nations. Dans cette perspective, la culture devient un moyen utilisé pour transmettre à l'étranger une représentation valorisante du pays, une image de marque (une forme de « Nation Branding » avant l'heure) également utile au secteur touristique et à l'industrie d'exportation. Le Service suisse d'ondes courtes fait ainsi avant tout des relations publiques, un avant-goût de ce que les Américains appelleront dans les années 1960 la « public diplomacy »
