Amanda Da Silva, chercheuse en migrations internationales, analyse les politiques migratoires de l’Union Européenne, à travers la notion de « sécurisation de l’immigration ». Ce courant théorique vient de l’école d’études critiques de la sécurité et a pour concepts centraux : menace, sécurité et frontières. Par la notion de sécurisation, l’immigration est conceptualisée par la communauté politique comme une source d’insécurité. Des frontières sont érigées pour protéger une société où les discours et les politiques migratoires restrictives cristallisent l’image de l’immigrant en tant que menace. Cette recherche révèle que l’absence d’accueil de la part des États et le manque d’information généralisé servent la construction de camps où les réfugiés sont à la merci du marché de l’immigration clandestine et de la violence.

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.

We investigate the dynamical properties of liquid GexSe100−x as a function of Ge content by first-principles molecular dynamic simulations for a certain number of temperatures in the liquid state. The focus is set on ten compositions (where x ≤ 33%) encompassing the reported flexible to rigid and rigid to stressed-rigid transitions. We examine diffusion coefficients, diffusion activation energies, glassy relaxation behavior, and viscosity of these liquids from Van Hove correlation and intermediate scattering functions. At fixed temperature, all properties/functions exhibit an anomalous behavior with Ge content in the region 18%-22%, and provide a direct and quantitative link to the network rigidity. [less ▲]

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 ▲]

Office blood pressure (OBP) coupled with 24-h ambulatory monitoring (24-h ABPM) or home self-monitoring (HBPM) allow a more accurate assessment of BP control in treated hypertensive patients and identification of different phenotypes of BP. ESH/ESC guidelines (2013) recommended 7 days of home measurements (3 days at least) but that duration is questioned. The present study examined if we can reduce, and to what extent, the 7-days schedule for home measurements in treated hypertensive kidney transplant recipients (ktr) while keeping a reliable assessment of their BP status?

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 ▲]
