This paper proposes a novel methodology for developing fire fragility functions for an entire steel building - meaning that the function is not specific to a location within the building. The aim is to characterize the probabilistic vulnerability of steel buildings to fire in the context of community resilience assessment. In developing the fragility functions, uncertainties in the fire model, the heat transfer model and the thermo-mechanical response are considered. In addition several fire scenarios at different locations in the building are studied. Monte Carlo Simulations and Latin Hypercube Sampling are used to generate the probability distributions of demand placed on the members and structural capacity relative to selected damage thresholds. By assessing demand and capacity in the temperature domain, the thermal and the structural problems can be treated separately to improve the efficiency of the probabilistic analysis. After the probability distributions are obtained for demand and capacity, the fragility functions can be obtained by convolution of the distributions. Finally, event tree analysis is used to combine the functions associated with fire scenarios in different building locations. The developed fire fragility functions yield the probability of exceedance of predefined damage states as a function of the fire load in the building. The methodology is illustrated on an example consisting in a prototype nine-story steel building based on the SAC project. [less ▲]

In the Western Highlands of Cameroon as in all other regions of the world where mountain agriculture is practiced, erosion and runoff pose a real threat to the sustainable preservation of natural resources. Generally, plots located on the slopes of the mountains in the Western Highlands have either become less productive or totally unproductive; this situation is exasperated by the scarcity of arable land which is largely attributed to cultural practices that do not take into account soil and water conservation methods. To better quantify the impacts of erosion and runoff on the different functions assigned to agriculture and agricultural holdings, this thesis has implemented tied ridging which is an unused soil and water conservation technique. We have thus compared the effectiveness of the existing soil preparation methods (ridging along the steepest slopes and flatbed cultivation) with tied ridging on two operating slopes namely 11% and 29%. The results showed a significant difference between the current practice (flatbed and ridging along the steepest slopes) and tied ridging in terms of soil loss (p = 0.003), yields (p = 0.003), and runoff water (p < 0.001). Under sole cropping of potato on a hectare of land, the tied ridging led to: (i) increase in populations of cultivated plants by 7%, (ii) significant reduction of runoff (lowered by a factor of seven) and soil loss (lowered by a factor of five), (iii) increase in yields by 80%, (iv) increase in farmer’s profitability by approximately 908388 FCFA.ha-1. The tied ridging needed 41% extra work regardless the slope of the land on which it was practiced. The tied ridging showed undeniable advantages: the stress of additional work was offset by the gain in yields for producer; additional work created additional job opportunities for the community; and tied ridging improved the conservation of soil and water for a healthy environment. Although the technique has several advantages, the provision of financial means for its implementation could be a negative point, because family labor supply is generally insufficient for its realization and the hired labor is expensive. Further work was dedicated to measuring the rate of adoption of the tied ridging technique and analysis of the determinants for adoption. The study showed that exploiting land ownership by farmers is a key factor in the implementation of soil conservation techniques. The results showed tied ridging adoption rates of 93% and 62% for dignitaries and other farmers respectively. Overall, access to land, operating slopes, and adoption of soil and water conservation techniques were significantly influenced by agronomic potentials of plots and socio-economic situation of farmers (p <0.05). Finally, in order to quantify the overall impact of tied ridging on the quality of surface water, we measured the proportion of sediments migrating from plots under the three soil preparation methods and entering to the river’s bed. The collected and measured sediments consisted of soil, plant residues, and other wastes (chemical packages, plastic casing used for irrigation, and food packages). The results showed that tied ridging cultivation method significantly reduced siltation of the Méloh River (p<0.05). Compared to 2012 and 2013, quantities of sediment decreased by 66% in 2014, the year in which the tied ridging technique was adopted on 75% of the plots. Thus the flatbed and ridging along the steepest slopes soil preparation methods are the principal cause of siltation and pollution of the Méloh River. The results of this research led to the following prospective approaches for improvement: (i) test the tied ridging technique with other crops and with different inter mounds’ spacing, (ii) study the facilitation of access to credit and creating farmer's organizations for promoting the adoption of tied ridging, (iii) test other soil and water conservation techniques such as live hedges, direct-sowing mulch-based crop (agroecology), and agroforestry, and (iv) conduct general limnologic studies of watersheds. The general limnology studies the surface waters according to their seasonal variations, and their physico-chemical and biological aspects. [less ▲]

Over recent decades, spreading environmental concern entailed the expansion of green chemistry analytical tools. Vibrational spectroscopy, belonging to this class of analytical tool, is particularly interesting taking into account its numerous advantages such as fast data acquisition and no sample preparation. In this context, Near-Infrared, Raman and mainly Surface-Enhanced Raman Spectroscopy (SERS) have thus gained interest in many fields including bioanalysis. The two former techniques only ensure the analysis of concentrated compounds in simple matrices, whereas the emergence of SERS improved the performances of vibrational spectroscopy to very sensitive and selective analyses. Complex SERS substrates were also developed enabling biomarker measurements, paving the way for SERS immunoassays. Therefore, in this paper, the strengths and weaknesses of these techniques will be highlighted with a focus on recent progress. [less ▲]

La formation a pour but de donner une introduction à la bande dessinée américaine indépendante, en apportant un éclairage spécifique sur la production contemporaine qui jouit actuellement d’un succès de librairie important dans nos contrées grâce au remarquable travail de traduction d’éditeurs comme Glénat, Delcourt ou Urban, entre autres. Le monde de la bande dessinée américaine ne se réduit en effet pas aux comics superhéroïques et aux grands éditeurs que sont Marvel et DC. Loin de ces formes sérielles et très codifiées, le séminaire présentera les auteurs et les œuvres phares des comics et graphic novels indépendants. Il soulignera les enjeux esthétiques et stylistiques de cette bande dessinée singulière. Un panorama historique de ces productions et un passage en revue d’une bibliographie spécialisée permettra aux bibliothécaires intéressé(e)s de mieux conseiller leurs lecteurs ou de se lancer dans de judicieuses acquisitions pour leur établissement.

Le jeu vidéo, né au sein de la culture hacker, est historiquement lié à la pratique du détournement et de la réappropriation. Cette tendance première s’actualise aujourd’hui dans nombre de pratiques qui prolongent le jeu hors de son espace premier et investissent d’autres supports : que l’on pense aux fanfictions, au modding, ou encore aux machinimas, le jeu vidéo est ponctuellement appréhendé par les joueurs non comme une œuvre fermée à consommer, mais comme un outil pour créer à partir de. La présente communication vise donc à étudier les détournements de jeux vidéo d’un point de vue formel, en mesurant et en caractérisant l’écart que ces œuvres « au second degré » construisent par rapport à une pratique consensuelle du jeu. Plus spécifiquement, nous tenterons ici de mettre au jour deux difficultés théoriques propres à l’étude du détournement de pratiques ludiques. [less ▲]

On voudrait ici interroger un trait curieux de l’histoire des catégories populaires du romanesque frappant par son (apparence de ?) paradoxe, et sur lequel il y aurait lieu, semble-t-il, de formuler quelques remarques. Ce phénomène concerne un discours qu’a pu tenir, de façon récurrente, le roman d’aventures du XIXe siècle à propos de lui-même et de ses romanciers. En effet, ce secteur productif a ressenti très tôt le besoin, d’un côté, de « s’autoriser du voyage » en quelque sorte, en plaçant ses récits, qu’ils soient plus ou moins fantaisistes, sous le signe de l’aventure vécue, de la relation, ou même du travelogue revendiqué (le paratexte, à cet égard, est patent – on en donnera un digest représentatif) ; mais d’un autre côté, à mesure que s’étoffait cette même production, elle voyait s’élever de grands devanciers sous l’autorité desquels pouvaient désormais se positionner des héritiers et/ou épigones à la mémoire plus ou moins heureuse : ainsi, depuis le titre de « Walter Scott américain » décerné à Fenimore Cooper (sans doute le premier cas attesté de notre phénomène), tout le siècle grouillera d’étiquettes accréditantes du même genre, par lesquelles des générations renouvelées de romanciers d’aventures se proposeront au public. Dans le cas de cette quête d’auteurs-garanties, c’est évidemment l’illustration d’un lignage générique qui est poursuivie. Ainsi – sans exhaustivité – parlera-t-on, dans les journaux et les discours périphériques, d’Alexandre Dumas comme du « Walter Scott français », de Gabriel Ferry comme du « Cooper français », de Gustave Aimard, ou même d’Emmanuel Gonzalès (dans la Gazette bibliographique de 1881) selon les cas, comme d’un « Cooper français » ou d’un « Mayne-Reid français » ; de Karl May comme du « Cooper allemand », de Salgari comme du (seul) « Verne italien », et même de Louis Boussenard comme du « Verne beauceron » ( !) Il se tisse là un réseau proliférant de cooptation d’auteurs et d’essais d’affiliation hautement génériques, dont on peut déjà observer, à ces quelques exemples, que ce geste fraye et se reproduit dans toutes les industries paralittéraires d’Europe. Comment le romancier assume-il ce paradoxe ? L’assume-t-il seulement, ou se complaît-il plutôt à jouer sur l’un ou l’autre tableau ? Qui est le romancier d’aventures – ou, plutôt, que veut-il être ? Plus profondément encore : où cette oscillation définitoire – contradictoire – débouchera-t-elle à la fin du siècle, et quel « pêché définitoire originel » dénonce-t-elle aux racines mêmes du roman d’aventures ? Nos remarques procéderont par études de cas précises, en s’efforçant de faire dialoguer ces décorticages particuliers avec la réflexion théorique et les hypothèses de réponses que nous tenterons de formuler. Entre l’ethos du vadrouilleur se disant secondairement écrivain (ou écrivain par accident) et l’héritier générique cherchant son Médiateur à la matière et aux codes indépendants et bien établis, notre argument voudra explorer, en tout cas, un lieu d’intense dialectique dans les dynamiques d’accréditation du récit paralittéraire dixneuvièmiste.

This paper investigates whether conditional accounting conservatism has informational benefits to financial market participants. Using a large sample of French firms over the period 2001-2014, we report that accounting conservatism improves the firm information environment by providing verifiable information. We specifically document that increases in accounting conservatism are associated with more accurate analyst earnings forecasts, less dispersed forecasts and less volatility in forecast revisions. We also provide evidence that increases in firm accounting conservatism lead to subsequent increases in stock market liquidity, tested on the price impact dimension. Overall, our findings are in line with conservatism being useful to financial markets participants such as financial analysts and investors. [less ▲]

In Todd Hignite's In the Studio, Charles Burns characterizes a scrapbook put together by his father as one of his “most prized possessions.” The scrapbook contains a collection of various comic strips which his father used for reference when dabbling in cartooning. This scrapbook is a symbol of the close bond between reading, collecting and drawing while underlining the importance of imitation and ‘swiping’ in the production and reception of comics. Burns, whose Tumblr “Johnny 23” could be seen as a digital equivalent to his father's scrapbook, is himself profoundly engaged in ‘swiping’ panels from ‘old’ comics, from American horror and romance comic books to Hergé's Tintin albums. This paper will explore the stakes of ‘swiping’ and quotation in the author's recent production. I will not only focus on his borrowings from Tintin and romance comics for his X'ed Out trilogy, but also on related projects with small-press publishers like Le Dernier Cri, B.ü.l.b. Comix, Cornélius. The way Burns turns to the archive of comics and redeploys it follows the random logic of Burroughs's cut-up technique, which not only recalls the cut-and-paste aesthetics of the scrapbook but is also echoed in the fragmented materiality of the project. However, Burns's cut-ups are not literally ‘cut up’ as much as they are drawn. Elaborating on Philippe Marion's influential concept of “graphiation,” this paper will analyze the citational practice of Charles Burns in medium-specific and historical terms, examining what it means to redraw the past of comics into the contemporary graphic novel. Indeed, how does his work walk the line between ‘individual’ and ‘collective’ graphic styles? How does it play with various conceptions of authorship and how does it negotiate the affects bound up with the appropriated works? [less ▲]

I propose a quick overview of four criteria whose combination delineates, to my opinion, what makes one an Austrian phenomenologist. On the proposed view, you qualify as an Austrian phenomenologist if and only if: 1. you acknowledge the authority of experience, 2. you think that philosophy needs psychological investigations at its basis, 3. you think that description is prior to explanation, and 4. you think that describing a mental state is analyzing it, that is, gaining a clear and distinct apprehension of its components.

Nanogels of controlled kinetic chain length were synthesized by cobalt-mediated radical cross-linking copolymerization (CMRccP) involving a vinyl monomer and a divinyl cross-linker. This strategy was first validated to achieve neutral poly(vinyl acetate) nanogels by CMRccP of vinyl acetate and divinyl adipate as cross-linker, at 40 °C, in presence of an alkyl- cobalt(III) serving both as initiator and controlling agent, using ethyl acetate as solvent. Poly(ionic liquid) nanogels were then directly obtained by CMRccP of N-vinyl-3-ethyl imidazolium bromide, in presence of 1,13-divinyl-3-decyl diimidazolium bromide as cross-linker. CMRccP experiments could be conducted either in organic solvent using dimethyl formamide or, more interestingly, in aqueous solution, demonstrating the robustness and the versatility of this one-step process. Chain extensions of PILs nanogels were also carried out in water, forming core-shell structures, thus opening new avenues in the design of functional nanogels. [less ▲]
