Non-methane hydrocarbons such as ethane are important precursors to tropospheric ozone and aerosols. Using data from a global surface network and atmospheric column observations we show that the steady decline in ethane concentrations that began in the 1970s halted between 2005 and 2010 in most of the Northern Hemisphere, and has since reversed. We calculate a yearly increase in ethane emissions in the Northern Hemisphere of 0.42 (+/-0.19) Tg/yr between mid-2009 and mid-2014. The largest increases in ethane and for the shorter-lived propane are seen over the central and eastern USA, with a spatial distribution that suggests North American oil and natural gas development as the primary source of increasing emissions. By including other co-emitted oil and natural gas non-methane hydrocarbons, we estimate a Northern Hemisphere total non-methane hydrocarbon yearly emission increase of 1.2 (+/-0.8) Tg/yr. Atmospheric chemical transport modelling suggests that these emissions could augment summertime mean surface ozone by several nanomoles per mole near oil and natural gas production regions. Methane/ethane oil and natural gas emission ratios suggest a significant increase in associated methane emissions; however, this increase is inconsistent with observed leak rates in production regions and changes in methane’s global isotopic ratio.

Over the past decades, market liquidity has been a major issue for stock market participants and even becomes one of the most important challenges since the recent financial crisis. In this context, this dissertation is centered on this topic and presents three empirical essays incorporating liquidity considerations in three different subfields of Finance, namely, asset pricing, portfolio allocation and mutual fund timing. The first essay (Chapter 2) is related to asset pricing and demonstrates that liquidity and quality are priced characteristics in the stock market, but their pricing is conditional on market volatility conditions. The second essay (Chapter 3) is devoted to portfolio allocation and shows that aggregate market liquidity shocks has a significant influence on optimal portfolio allocations. In addition, it emphasizes that liquidity-responsive strategies could be a valuable tool for investors and portfolio managers to actively manage risks and capture return opportunities. The third essay (Chapter 4) focuses rather on mutual fund timing and examines what style liquidity timing skills may mutual fund managers possess. This study highlights that, in anticipation of aggregate market liquidity changes, mutual funds do not switch their investments between stocks and cash but they rather switch between only small and large stocks. Overall, the main message to take away from this research is that investors and portfolio managers should take into consideration both the liquidity of their individual stocks and the liquidity of the market as a whole.

Lignin is a cross-linked phenol polymers from plant cells wall and is the third most abundant organic material after cellulose and hemicelluloses. This substance was studied as a flame retardant for various polymers and represents an interesting opportunity to create more eco-friendly and safer plastics and resins. This poster explains one potential technology to extract lignin: the organosolv treatment. [less ▲]

Nowadays, adolescents are totally integrated into the digital generation. Tablets, smartphones, and other apps belong to their normal life while most of their teachers sometimes try yet to discover what a computer is. In physical education, several authors showed that new tools can be used during practical lessons in a way to improve the learning environment and motivation of the students. As the videotape recorder in the past, current technologies represent resources that have to be adapted to the teaching strategies and not considered as miraculous tools that will solve all problems. On the other hand, one has to consider that youth are particularly attracted by digital tools that offers a growing range of possibilities to stimulate students’ critical thinking, autonomy, and involvement. This study aimed to help a group of PE teachers to use new technologies in their classes. Considering that his colleagues and he (grades 10-12) were not effective in using new technologies, one PE teacher from a secondary school invited us to propose a series of activities in order to let them identifying a way to take benefit from available ICTs. An interactive process has been implemented in order to put the teachers in the center of their development. A four steps approach was designed: (1) identification of the perceived benefits of ICTs and of the available tools, selection of one objective and one tool (4 teachers/5); (2) organization of a focus group to identify a practical way to use the selected tool (2/3); (3) preparation of a model lesson (3/3); follow up after 6 months (3/3). For several reasons, even if interesting projects of lessons were developed, they did not have been implemented. The study underlines the difficulties that PE teachers can meet when trying to innovate. [less ▲]

Interdisciplinarité : si la recherche en bande dessinée s'est, dans une certaine mesure, constituée en discipline (associations disciplinaires, congrès et conférences, revues scientifiques, etc.), son inscription au cœur des institutions reste tributaire de l'insertion de ces recherches au sein d'autres départements et, donc, d'autres disciplines. Le cas d'ACME offre un exemple de structuration au sein de l'institution universitaire qui s'exécute autour d'un travail de rassemblement collectif interdisciplinaire, chaque membre apportant les outils méthodologiques de sa formation et de sa discipline : ACME est ainsi autant ancré dans les études littéraires que dans l'histoire de l'art ou les études en communication. Les résultats de ces recherches, comme le livre L'Association : une utopie esthétique et éditoriale1, exhibent une convergence de regards, jetant différents perspectives sur un objet commun. Le travail interdisciplinaire se situe donc à deux niveaux : à la fois dans le regard porté par le chercheur sur un objet qui n'« appartient » pas traditionnellement à la discipline à laquelle il ou elle est formé-e (transdisciplinarité), et dans les résultats concrets de publication qui unifient différentes approches disciplinaires (pluridisciplinarité). Objets d'étude et échelles d'analyse : pour permettre cette convergence de regards disciplinaires, ACME s'est rassemblé autour d'objets d'étude permettant ce genre de rassemblement, d'où le choix d'objets éditoriaux et collectifs (L'Association, Spirou) ou de questions transversales (la dissidence, l'abstraction). Ces études conjuguent plusieurs perspectives et échelles d'analyses : des propositions systémiques et englobantes aux analyses les plus fines d'œuvres singulières. Entre distant reading et close reading, le groupe ACME, par le biais de son interdisciplinarité, se livre peut-être à une forme d'entre-deux, une « mid-level reading », de la bande dessinée qui rend compte des multiples interactions entre macro- et micro-niveau. Dimension transnationale : en lien avec l'interdisciplinarité, le groupe ACME a aussi mis en avant le dialogue des langues et des traditions critiques, qui résulte en partie de l'ancrage de certains de ses membres dans des départements de langues étrangères (anglais, néerlandais). Ce choix s'est de plus concrétisé dans le bilinguisme opté pour la collection « ACME » aux Presses universitaires de Liège. Alors que les recherches en bande dessinée dans le monde francophone et anglo-saxon se déroulent encore trop souvent en parallèle et/ou dans une ignorance respective, ACME se joint ainsi à d'autres initiatives d'établir un dialogue constructif entre ces deux traditions critiques.

Methane is the second most important greenhouse gas contributing to climate warming. The open ocean is a minor source of methane to the atmosphere. We report intense methane emissions from the near-shore southern region of the North Sea characterized by the presence of extensive areas with gassy sediments. The average flux intensities (~130 μmol m−2 d−1) are one order of magnitude higher than values characteristic of continental shelves (~30 μmol m−2 d−1) and three orders of magnitude higher than values characteristic of the open ocean (~0.4 μmol m−2 d−1). The high methane concentrations (up to 1,128 nmol L−1) that sustain these fluxes are related to the shallow and well-mixed water column that allows an efficient transfer of methane from the seafloor to surface waters. This differs from deeper and stratified seep areas where there is a large decrease of methane between bottom and surface by microbial oxidation or physical transport. Shallow well-mixed continental shelves represent about 33% of the total continental shelf area, so that marine coastal methane emissions are probably under-estimated. Near-shore and shallow seep areas are hot spots of methane emission, and our data also suggest that emissions could increase in response to warming of surface waters. [less ▲]
