Predicting species distributions for conservation decisions.

Species distribution models (SDMs) are increasingly proposed to support conservation decision making. However, evidence of SDMs supporting solutions for on-ground conservation problems is still scarce in the scientific literature. Here, we show that successful examples exist but are still largely hidden in the grey literature, and thus less accessible for analysis and learning. Furthermore, the decision framework within which SDMs are used is rarely made explicit. Using case studies from biological invasions, identification of critical habitats, reserve selection and translocation of endangered species, we propose that SDMs may be tailored to suit a range of decision-making contexts when used within a structured and transparent decision-making process. To construct appropriate SDMs to more effectively guide conservation actions, modellers need to better understand the decision process, and decision makers need to provide feedback to modellers regarding the actual use of SDMs to support conservation decisions. This could be facilitated by individuals or institutions playing the role of 'translators' between modellers and decision makers. We encourage species distribution modellers to get involved in real decision-making processes that will benefit from their technical input; this strategy has the potential to better bridge theory and practice, and contribute to improve both scientific knowledge and conservation outcomes.

Analysis, modelling and classification of geospatial data using machine learning

The research considers the problem of spatial data classification using machine learning algorithms: probabilistic neural networks (PNN) and support vector machines (SVM). As a benchmark model simple k-nearest neighbor algorithm is considered. PNN is a neural network reformulation of well known nonparametric principles of probability density modeling using kernel density estimator and Bayesian optimal or maximum a posteriori decision rules. PNN is well suited to problems where not only predictions but also quantification of accuracy and integration of prior information are necessary. An important property of PNN is that they can be easily used in decision support systems dealing with problems of automatic classification. Support vector machine is an implementation of the principles of statistical learning theory for the classification tasks. Recently they were successfully applied for different environmental topics: classification of soil types and hydro-geological units, optimization of monitoring networks, susceptibility mapping of natural hazards. In the present paper both simulated and real data case studies (low and high dimensional) are considered. The main attention is paid to the detection and learning of spatial patterns by the algorithms applied.

Individualizing exposure therapy of PTSD: the case of Caroline

In therapy for chronic posttraumatic stress disorder (PTSD), prolonged exposure (PE) to stimuli associated with an original trauma experience is considered a state-of-the-art treatment method. The present case report outlines the use of Foa and Rothbaum's (1998) manual for this type of treatment in the year-long, 40-session treatment of Caroline, an adult female victim of child sexual abuse. The manual was supplemented by Caspar's (1995, 2007) Plan Analysis technique for individualized case formulation and treatment planning, along with Caspar's concept of the Motive-Oriented Therapeutic Relationship (MOTR). As indicated by standardized, quantitative measures, by changes in the client's behavior patterns, and by the client's subjective report, the treatment was very effective. An analysis of the therapy process illustrates the importance of a combination of manual-based procedures with individualized case formulations and interventions. The case is discussed in the context of enhancing the cognitive-behavioral treatment of PTSD.

Spatiotemporal analysis of forensic case data: a visualisation approach

Whether for investigative or intelligence aims, crime analysts often face up the necessity to analyse the spatiotemporal distribution of crimes or traces left by suspects. This article presents a visualisation methodology supporting recurrent practical analytical tasks such as the detection of crime series or the analysis of traces left by digital devices like mobile phone or GPS devices. The proposed approach has led to the development of a dedicated tool that has proven its effectiveness in real inquiries and intelligence practices. It supports a more fluent visual analysis of the collected data and may provide critical clues to support police operations as exemplified by the presented case studies.

LEVERAGING SANDBOX IMMERSIVE 3D VIRTUAL WORLDS TO DEVELOP DO-IT- YOURSELF TEACHING GAMES: IMPLEMENTATION TO MARKETING CASE STUDY TEACHING IN SECOND LIFE

Games are powerful and engaging. On average, one billion people spend at least 1 hour a day playing computer and videogames. This is even more true with the younger generations. Our students have become the < digital natives >, the < gamers >, the < virtual generation >. Research shows that those who are most at risk for failure in the traditional classroom setting, also spend more time than their counterparts, using video games. They might strive, given a different learning environment. Educators have the responsibility to align their teaching style to these younger generation learning styles. However, many academics resist the use of computer-assisted learning that has been "created elsewhere". This can be extrapolated to game-based teaching: even if educational games were more widely authored, their adoption would still be limited to the educators who feel a match between the authored games and their own beliefs and practices. Consequently, game-based teaching would be much more widespread if teachers could develop their own games, or at least customize them. Yet, the development and customization of teaching games are complex and costly. This research uses a design science methodology, leveraging gamification techniques, active and cooperative learning theories, as well as immersive sandbox 3D virtual worlds, to develop a method which allows management instructors to transform any off-the-shelf case study into an engaging collaborative gamified experience. This method is applied to marketing case studies, and uses the sandbox virtual world of Second Life. -- Les jeux sont puissants et motivants, En moyenne, un milliard de personnes passent au moins 1 heure par jour jouer à des jeux vidéo sur ordinateur.

Les études montrent que les élèves qui se trouvent en échec scolaire dans les salles de classes traditionnelles, passent aussi plus de temps que leurs homologues à jouer à des jeux vidéo. lls pourraient potentiellement briller, si on leur proposait un autre environnement d'apprentissage. Les enseignants ont la responsabilité d'adapter leur style d'enseignement aux styles d'apprentissage de ces jeunes générations. Toutefois, de nombreux professeurs résistent lorsqu'il s'agit d'utiliser des contenus d'apprentissage assisté par ordinateur, développés par d'autres. Ceci peut être extrapolé à l'enseignement par les jeux : même si un plus grand nombre de jeux éducatifs était créé, leur adoption se limiterait tout de même aux éducateurs qui perçoivent une bonne adéquation entre ces jeux et leurs propres convictions et pratiques. Par conséquent, I'enseignement par les jeux serait bien plus répandu si les enseignants pouvaient développer leurs propres jeux, ou au moins les customiser.

Etat des lieux et potentiel de l'agriculture urbaine en Suisse : analyse de deux projets d'agriculture urbaine sous l'angle des régimes institutionnels des ressources naturelles

Ce travail de recherche dresse un panorama de l'état du développement des pratiques d'agriculture urbaine en Suisse et analyse le potentiel que celles-ci pourraient y développer, compte tenu des particularités du contexte national. La démarche adoptée suit une logique allant du général au particulier, de la théorie à la pratique, du descriptif vers l'analytique. Dans un premier temps, l'agriculture urbaine est abordée sous un angle conceptuel, comprenant un retour historique sur la relation ville-campagne et sur l'apparition récente du terme d'agriculture urbaine, un tour d'horizon de la littérature sur le sujet, une revue de ses diverses approches scientifiques et la circonscription des enjeux de sa définition. Dans un deuxième temps, l'agriculture urbaine est envisagée sous sa forme pratique, en Suisse comme à l'étranger. En ressort un inventaire étendu de ses différents types de mises en application, auquel correspond un panel d'atouts identifiés selon les trois versants du développement durable : social, écologique et économique. En troisième lieu les spécificités du contexte helvétique sont étudiées afin de comprendre quel est le cadre dans lequel le potentiel de l'agriculture urbaine pourrait se développer. Finalement, ce sont deux cas concrets d'agriculture urbaine qui sont analysés et évalués dans les détails, selon l'approche dite des régimes institutionnels des ressources naturelles (RIRN): le « plantage » lausannois du quartier de la Bourdonnette et le Stadiongarten dans le quartier Kreis 5 à Zurich. Au fil de cette recherche, il apparaît que l'agriculture urbaine révèle toute une série d'avantages en termes de développement durable, alors même que les villes suisses sont unanimement reconnues comme présentant un déficit dans ce domaine. De même, malgré les bienfaits importants que présentent ses diverses pratiques, l'agriculture urbaine reste encore très peu répandue en Suisse, le concept lui-même n'apparaissant que très rarement dans le discours des pouvoirs publics. Le principal frein à l'agriculture en ville est identifié comme étant le manque d'espace disponible dans les agglomérations, contrainte pourtant largement surmontable en y regardant de plus près. De par sa configuration topographique, le territoire suisse est particulièrement sujet à une étroite proximité entre espaces urbains et étendues agricoles, accroissant de ce fait la problématique de l'étalement urbain et du mitage du paysage. Parmi les enjeux de la lutte contre ces phénomènes concomitants, l'agriculture urbaine aurait un rôle important à jouer. En conclusion, une série de recommandations sont proposées afin que les projets d'agriculture urbaine puissent se développer et perdurer en Suisse. Abstract : This research paper provides an overview of the state of development of urban agriculture practices in Switzerland. It analyzes their potential of expansion while taking into account the particularities of the national context. The method follows a general to particular, theory to practice and descriptive to analytical reasoning. Firstly, urban agriculture is approached through a conceptual view, including a historical overview of the relationship between town and country and of the recent appearance of the term "urban agriculture". An outline of the literature on the subject, an examination of its various scientific approaches and riding issues of its definition are elaborated as well. In a second step, urban agriculture is considered in its practical form, both in Switzerland and abroad. From this we created an extensive inventory of various types of implementations which corresponds to a panel of assets identified according to the three aspects of sustainable development: social, ecology and economics. Thirdly the specificities of Swiss context are studied in order to understand the frame in which the potential of urban agriculture could be developed. Finally, two case studies of urban agriculture are analyzed and evaluated in detail, according to the so-called institutional regimes of natural resources (RIRN) approach: the "plantage" of the Bourdonnette neighborhood in Lausanne and the "Stadiongarten" in the Kreis 5 neighborhood in Zurich. Throughout this research, urban agriculture reveals a number of advantages in terms of sustainable development, even though the Swiss cities are unanimously recognized as having a deficit in this area. As well, despite the significant benefits that are its various practices, urban agriculture is still very uncommon in Switzerland, the concept itself appearing only rarely in public debates. The main obstacle to city agriculture is identified as the lack of available space in urban areas, however this constraint can easily be surpassed. By its topographical configuration, Switzerland is particularly prone to a close proximity between urban and agricultural spaces, thereby increasing the problems of urban sprawl. Among the stakes in the struggle against these interrelated phenomena, urban agriculture could play an important role. In conclusion, a series of recommendations are proposed so that urban agriculture projects can grow and persist in Switzerland.

A frequency distribution approach to hotspot identification

We present a new global method for the identification of hotspots in conservation and ecology. The method is based on the identification of spatial structure properties through cumulative relative frequency distributions curves, and is tested with two case studies, the identification of fish density hotspots and terrestrial vertebrate species diversity hotspots. Results from the frequency distribution method are compared with those from standard techniques among local, partially local and global methods. Our approach offers the main advantage to be independent from the selection of any threshold, neighborhood, or other parameter that affect most of the currently available methods for hotspot analysis. The two case studies show how such elements of arbitrariness of the traditional methods influence both size and location of the identified hotspots, and how this new global method can be used for a more objective selection of hotspots.

Urban environments and situated institutions : everyday governance in west Bengal

How do processes of power shape the urban environment in small Indian cities? On a day-to-day basis, who actually controls access to and the use of environmental resources? How is this done? Answering these questions contributes to our ability to develop a nuanced understanding the urban condition. In order to investigate these questions an actor-oriented approach is developed, drawing on the anthropological literatures on everyday governance and the everyday state. This conceptual framework informs an urban political ecology approach oriented towards everyday practices and the micro-politics of the (re)production of urban socio-natures. This thesis employs a mixed methods approach to qualitative research. Three cases are presented to explore: para (neighbourhood) clubs as governance actors, the governance of the urban pondscape, and the urban political ecology of solid waste management. These case studies serve to highlight how power shapes the (re)production of urban socio-natures through the everyday environmental governance practices of a complex network of governance actors. This work further demonstrates how multiple intersectionalities, including class, caste and access to political and social authority, shape these practices and their outcomes. Finally, the manner in which balances of power, place making and the formation of subject positions may both result from and shape everyday environmental governance practices and their outcomes is explored. This empirical investigation makes a number of contributions to the literature. It has explores the hereto-understudied topics of environmental governance in small cities in India, the urban political ecologies of non-piped water and of solid waste, and the role of clubs as governance actors. It further contributes to conversations within the literature on how to deepen and broaden Urban Political Ecology by engaging with everyday practices, and cases of ordinary, not-openly contested socio-natures. -- Comment les processus de pouvoir influencent-ils l'environnement urbain dans les petites villes indiennes ? Au quotidien, qui contrôle l'accès et l'utilisation des ressources environnementales ? Comment ce contrôle s'exerce-t-il ? Répondre à ces questions contribue au développement d'une compréhension nuancée de la condition urbaine. Afin d'explorer ces questions une approche actor-oriented de la gouvernance quotidienne est développée, faisant appel aux littératures anthropologiques de la gouvernance quotidienne et de l'everyday state. Ce cadre conceptuel établit ainsi une approche d'Urban Political Ecology orientée vers les pratiques quotidiennes et la micro- politique de la (re) production des socio-natures urbaines. Cette thèse emploie des méthodes qualitatives mixtes. Trois cas sont présentés afin d'étudier : les clubs para (quartier) comme acteurs de la gouvernance; la gouvernance de la pondscape urbaine; et l'urban political ecology de la gestion des déchets solides. Ces études de cas permettent de mettre en lumière la façon dont le pouvoir influence la (re)production des socio-natures urbaines par le biais des pratiques quotidiennes de gouvernance environnementale d'un réseau complexe d'acteurs. Ce travail démontre également comment plusieurs intersectionnalités, y compris la classe, la caste et l'accès au pouvoir politique et social, façonnent ces pratiques de gouvernance et leurs produits. Finalement, cette recherche explore la manière dont les équilibres de pouvoir, la fabrication de lieux et la formation de la position du sujet peuvent à la fois résulter de et contribuer à façonner les pratiques quotidiennes de gouvernance environnementale et leurs produits. Cette investigation empirique fait ainsi plusieurs contributions à la littérature. Elle explore les questions jusque-là sous-étudiées de la gouvernance environnementale dans les petites villes en Inde, de l'urban political ecology de l'eau non courante et des déchets solides, ainsi que du rôle des clubs comme acteurs de la gouvernance. Celle-ci contribue également à des débats sur la façon d'approfondir et d'élargir l'urban political ecology en travaillant sur les pratiques quotidiennes, et sur des cas de socio-natures ordinaires, pas ouvertement contestées.
