Modern Directional Statistics collects important advances in methodology and theory for directional statistics over the last two decades. It provides a detailed overview and analysis of recent results that can help both researchers and practitioners. Knowledge of multivariate statistics eases the reading but is not mandatory. The field of directional statistics has received a lot of attention over the past two decades, due to new demands from domains such as life sciences or machine learning, to the availability of massive data sets requiring adapted statistical techniques, and to technological advances. This book covers important progresses in distribution theory, high-dimensional statistics, kernel density estimation, efficient inference on directional supports, and computational and graphical methods.

La thèse de doctorat a été consacrée à l’étude d’un ensemble d'inscriptions françaises des XIe et XIIe siècles par lesquelles un individu s’attribue la réalisation d’un ouvrage artistique ou monumental. En renouvelant l’approche traditionnelle de ces « signatures », liée plutôt à une démarche attributive, et en envisageant ces documents épigraphiques dans leur double dimension de texte et d’objet, en ont été sondés les mécanismes de production et les fonctions. L’étude est introduite par un bilan historiographique et une réflexion théorique sur la signature épigraphique, qui y est redéfinie comme « une inscription dont la fonction est d’assigner à un ou plusieurs individus, au moyen d’un énoncé verbal, la responsabilité d’une oeuvre à laquelle l’inscription est matériellement et/ou visuellement rattachée » (sont donc exclus de l’inventaire les anthroponymes isolés et les marques lapidaires ou glyptographes). La première partie de la thèse aborde le problème de la valeur auctoriale de ces inscriptions. Les textes des signatures épigraphiques recensées livrent en effet des informations extrêmement laconiques sur l’identité du signataire et sur son rôle dans la fabrication de l’oeuvre. Il est donc délicat d’attribuer systématiquement ces attestations à l’artiste, d’autant plus qu’une telle catégorie de pensée apparaît comme étrangère à la mentalité du Moyen Âge central. En outre, le problème de la connaissance de l'écrit de la part des artistes avait jusqu’à présent été négligé, alors qu’il est clairement en lien avec la réalisation des signatures épigraphiques en tant que produits écrits. La seconde partie de la thèse s’attache donc à évaluer la capacité à écrire de ceux qui ont exécuté ces inscriptions et à sonder les contextes au sein desquels il leur était possible d’acquérir les compétences culturelles et techniques nécessaires. L’analyse technique et linguistique de cette documentation a permis de démontrer des situations d’alphabétisation variées, mais attestant toujours un rapport actif à l’écrit de la part de l’artisan chargé de l’inscription, contrairement à ce que l’on pensait communément auparavant. Un troisième et dernier volet de la réflexion a porté sur les enjeux de l’inscription publique du nom d’un individu en association à une oeuvre monumentale. En étudiant la mise en scène visuelle des signatures, il est apparu que leurs caractéristiques matérielles et topographiques ne sont pas toujours en adéquation avec l’objectif de publicité universelle qu’on leur a souvent reconnu et qui ferait de ces inscriptions une tribune d’affichage de l’artiste et de son talent. Par cette analyse des conditions de réception et la mise en relation des signatures avec les pratiques liturgiques de nomination, est donc proposée, pour le contexte étudié (France, XIe-XIIe s.), une interprétation de ce geste singulier d’écriture dans une perspective avant tout ecclésiologique et eschatologique. Dans le volume d’annexes de la thèse, chacune des 51 inscriptions encore conservées et étudiées dans la synthèse est présentée sous la forme d’une notice analytique. Ce catalogue est suivi d’un tableau synthétisant les données relatives au métier et au statut social des artisans de la base ArtiChO (Artistes et artisans dans les chartes antérieures à 1121 conservées en France) conçue pour organiser et exploiter les 140 actes issus de la base TELMA (http://www.cn-telma.fr/originaux/index/) mentionnant, à titre divers, des artistes et artisans.

Affective forecasting is an ability that allows the prediction of the hedonic outcome of never-before experienced situations, by mentally recombining elements of prior experiences into possible scenarios, and pre-experiencing what these might feel like. It has been hypothesised that this ability is uniquely human. For example, given prior experience with the ingredients, but in the absence of direct experience with the mixture, only humans are said to be able to predict that lemonade tastes better with sugar than without it. Non-human animals, on the other hand, are claimed to be confined to predicting—exclusively and inflexibly—the outcome of previously experienced situations. Relying on gustatory stimuli, we devised a non-verbal method for assessing affective forecasting and tested comparatively one Sumatran orangutan and ten human participants. Administered as binary choices, the test required the participants to mentally construct novel juice blends from familiar ingredients and to make hedonic predictions concerning the ensuing mixes. The orangutan’s performance was within the range of that shown by the humans. Both species made consistent choices that reflected independently measured taste preferences for the stimuli. Statistical models fitted to the data confirmed the predictive accuracy of such a relationship. The orangutan, just like humans, thus seems to have been able to make hedonic predictions concerning never-before experienced events. [less ▲]

The thesis is devoted to research of theoretical foundations, international and domestic trends of environmental taxation from the perspective of its use to reduce the excessive burden of economic activity on environment. It was developed the theoretical approaches to the study of the essence and public purpose of environmental taxation as a method of reducing the excessive burden on the environment. The features of the essential characteristics of environmental taxes were determined and include: the prevailing regulatory function on fiscal one; focus on harmonization of tax and environmental policies, reducing the tax base; providing commercial attractiveness of innovation and development of „clean” technologies; desirability manifestation of substitution effect; the prevailing of the „polluter pays” principle over paying capacity principle; internalization of negative externalities and minimization of excessive tax burden as a condition of optimal environmental taxes; imperative introducing specific rates of indirect taxes and increasing and reducing of the regulatory potential of environmental taxation depends on determined factors. It was deepened conceptual and categorical apparatus of the theory of taxation by clarifying the definition of „environmental taxes system„ as a combination of taxes and duties (mandatory payments) designed for achieving specific, well-defined environmental objectives which create price incentives for taxpayers to reduce the excessive burden on environment, compensation of environmental damage to society, improving energy and resource efficiency, which ultimately ensures the improvement of the ecological situation and welfare of population. Developed analytical research tool was used for evaluation the effectiveness of environmental taxation, the existing theoretical approaches to its development and implementation in the context of the experience of foreign countries. A structural-functional analysis of the environmental tax was conducted, and it was assessed the efficiency of energy taxes, analyzed the effectiveness of taxes on environmental pollution. That proved that, compared with developed countries, environmental taxes insufficiently perform tasks of catalyzing decoupling ties and unrealized potential of environmental energy taxes, transport taxes, taxes on resources and direct taxes on pollution exists in Ukraine. However, implementation of fiscal potential of environmental taxation should occur in interconnection with the level of purchasing power. It was defined the directions of realization of the energy taxes potential, on pollution of environment and the ways of improving information provision of administration of environmental taxes. The conclusion about expediency of introduction of adjustment coefficients tax rates depending on the environmental limits on pollution was made. It was proved the expediency of narrowing the tax base of environmental tax for focusing the regulatory impact of environmental tax on the strategic targets of environmental policy. The introduction of differentiation of excise tax rates on gas oil in Ukraine was proposed, according to environmental standards that operate in Ukraine. The scheme of inter-institutional communication on information provision of environmental taxes administration was created will shape the fiscal authorities, and tax payer’s history to draw conclusions about the completeness fulfillment of tax obligations.
