La désobéissance comme principe de la démocratie
Authors: Laugier Sandra 
Published: December 2015

Cet article examine les justifications de la désobéissance civile à partir d’un principe moral, qui n’est pas la liberté abstraite mais la confiance en soi : elle encourage l’individu à refuser la loi commune et acceptée des autres, en se fondant sur sa propre conviction qu’elle est injuste et indigne. Loin de marquer un rejet ou une marge du politique, les actes de désobéissance en appellent à une extension des droits et des libertés qu’une démocratie devrait assurer à ses citoyens. On ne désobéit qu’en démocratie – quand on n’a plus dans la vie publique les conditions de la conversation où l’on pourrait raisonnablement exprimer son différend, quand on est dépossédé de sa voix. La désobéissance est alors un rappel du principe démocratie, qui est l’expression égale et inconditionnelle de chacun.
Fonctionnaire, obéir/désobéir
Authors: Chauvet Clément 
Published: December 2015

Le droit de la fonction publique civile consacre un devoir d’obéissance solidement ancré, qui connaît des exceptions sous forme d’un devoir ou d’un droit de désobéissance. Le binôme « obéissance-désobéissance » montre cependant un certain nombre de paradoxes résultant d’une opposition entre deux impératifs contradictoires : protéger l’administration, le cas échéant contre la désobéissance ; protéger l’agent, éventuellement par l’obéissance à un ordre qui aurait dû être ignoré.

Perception des participants à un concours créatif
Authors: Renault Sophie 
Published: December 2015

Via la sphère électronique, de nombreuses organisations sollicitent la force créative de la foule comme source de création de valeur. Il est alors question de cocréation, de marketing participatif ou bien encore de crowdsourcing. Alors que ces concepts s’entrecroisent, c’est plus spécifiquement sur le crowdsourcing que notre recherche se porte. Il s’agit pour une organisation d’externaliser vers la foule des activités traditionnellement réalisées en interne ou confiées à des prestataires extérieurs. À l’appui d’une méthodologie qualitative, notre recherche appréhende la perception des participants à des concours créatifs : comment comprennent-ils le choix d’une marque de recourir à leurs compétences? Quel regard portent-ils alors sur la marque? Dans une approche exploratoire, notre recherche se fonde sur le suivi de 40 participants au concours de création média porté par la marque Kinder Maxi sur la plate-forme eYeka.

Authors: Ghali Zohra , Toukabri Maher 
Published: December 2015

S’inscrivant dans une perspective relationnelle, l’objet de cette recherche est de mieux spécifier le lien causal entre les émotions ressenties dans un lieu visité et l’attachement à ce dernier tout en étudiant le rôle médiateur de l’immersion dans l’expérience de visite. Les résultats issus d’une enquête, menée auprès de 350 visiteurs de médina de Tunis, confirment la significativité du lien causal étudié et montrent que les émotions ressenties lors de visites de médina (plaisir, activation), renforcées par un état d’immersion vécu par le visiteur, permettent de développer une proximité psychologique et un attachement au lieu visité. Ces résultats permettent alors de suggérer des pistes d’amélioration aux professionnels du secteur touristique en Tunisie.
Crise du secteur bancaire classique et plaidoyer pour une banque universelle durable :
Authors: Wangani Simon 
Published: December 2015

La crise bancaire et financière qui a commencé en 2008 et qui se poursuit aujourd’hui a ébranlé la solidité même des systèmes financiers nationaux, européens et mondiaux. L’exigence du développement durable s’installe solidement dans les politiques publiques et dans les stratégies des entreprises. Le processus, déjà bien amorcé avant l’éclatement de la crise mondiale, a été accéléré par elle. Car la crise renforce les impératifs au cœur du développement durable : moins de court-terme et plus de projets et d’actions sur le long terme, plus de transparence, une meilleure gouvernance tant au plan macro-économique que micro-économique. Cet article a pour objectif de proposer des alternatives bancaires qui redonnent aux institutions financières et aux consommateurs les moyens de développer d’autres pratiques financières basées sur des principes dont les objectifs sont à long terme.
Insect assemblages associated with the exotic riparian shrub Russian olive (Elaeagnaceae), and co-occurring native shrubs in British Columbia, Canada
Authors: Collette Liana K.D. , Pither Jason 
Published: December 2015

AbstractRussian olive (Elaeagnus angustifolia Linnaeus; Elaeagnaceae) is an exotic shrub/tree that has become invasive in many riparian ecosystems throughout semi-arid, western North America, including southern British Columbia, Canada. Despite its prevalence and the potentially dramatic impacts it can have on riparian and aquatic ecosystems, little is known about the insect communities associated with Russian olive within its invaded range. At six sites throughout the Okanagan valley of southern British Columbia, Canada, we compared the diversity of insects associated with Russian olive plants to that of insects associated with two commonly co-occurring native plant species: Woods’ rose (Rosa woodsii Lindley; Rosaceae) and Saskatoon (Amelanchier alnifolia (Nuttall) Nuttall ex Roemer; Rosaceae). Total abundance did not differ significantly among plant types. Family richness and Shannon diversity differed significantly between Woods’ rose and Saskatoon, but not between either of these plant types and Russian olive. An abundance of Thripidae (Thysanoptera) on Russian olive and Tingidae (Hemiptera) on Saskatoon contributed to significant compositional differences among plant types. The families Chloropidae (Diptera), Heleomyzidae (Diptera), and Gryllidae (Orthoptera) were uniquely associated with Russian olive, albeit in low abundances. Our study provides valuable and novel information about the diversity of insects associated with an emerging plant invader of western Canada.
The Return of Mythic Voice in the Aporias of Narcissism: Pleshette DeArmitt’s Ethical Idea
Authors: Beardsworth Sara 
Published: December 2015

The ordeal of mourning, being so much harder than any thought its experience may deliver, bears out the impression developed in Julia Kristeva’s opening to The Severed Head—that thought is swift. She has recognized as well as anyone the interplay of blindness and insight. Nothing brings all this into starker evidence than the premature death of a loved other, a friend, or a true assistant in life and thought. There is a reminder in this that the new narratives of subjectivity on which Kristeva places a high value, and certainly the long life of meaning in the world, come at the price of the loss and mourning of our loved others. Pleshette DeArmitt’s book, The Right to Narcissism: A Case for an Im-possible Self-Love, has given the condition of narcissism an intricate place in this difficult if promising work.
Quantifying Local Capillary Trapping Storage Capacity Using Geologic Criteria
Authors: Ren Bo , Bryant Steven L. , Lake Larry W. 
Published: December 2015

Abstract
The capillary pressure heterogeneity or local capillary trapping (LCT) determines the final distribution of CO2 in a saline aquifer during geological carbon sequestration. This locally trapped CO2 would not escape from the storage formation even if caprock integrity is compromised. It is, therefore, essential to predict the extent and storage capacity of LCT during the design of GCS projects.
This work employs a fast method based on the geologic criteria to estimate the structures of local capillary traps. The method assumes a critical capillary entry pressure (CCEP) and a geostatistical realization of the reservoir entry pressure field as inputs. It then finds the capillary barriers inside the domain and identifies the grid blocks beneath clusters of barriers. These grid blocks are the local capillary traps. The criterion for choosing the CCEP is important, and we suggest a criterion in this work.
We verify this algorithm by full-physics simulations in small 2D and 3D domains. We employ a large CO2 injection rate (Ngr~0.1) to fully sweep the storage domain, followed by a long period of buoyant flow to allow for complete charging of those local capillary traps. We test several CCEPs to determine the most physically representative value by comparing the LCT predicted from both methods. We find that a single value of CCEP enables the geologic algorithm to give a very good approximation of LCT distribution as well as LCT volume in uncorrelated and weakly correlated porous media. This means that the concept of CCEP is a reasonable approximation to the physical process by which traps are filled.
LCT can be described in terms of percolation theory. The percolation threshold arises from the competition between connected clusters of barriers and connected clusters of local traps. We show that both the percolated CCEP (corresponding to the percolation of LCT) and optimal CCEP (corresponding to the best match between geologic criteria and full-physics simulation) change with each other in a predictable linear way for the uncorrelated capillary entry pressure field.
Interannual variability of South Equatorial Current bifurcation and western boundary currents along the Madagascar coast
Authors: Yamagami Y. , Tozuka T. 
Published: December 2015

AbstractThe South Equatorial Current (SEC) in the southern Indian Ocean bifurcates at the east coast of Madagascar into the Northeast and Southeast Madagascar Currents (NEMC and SEMC, respectively). In observational and reanalysis data, interannual variations of the NEMC and SEMC transports are strongly correlated with those of the SEC transport, rather than those of the SEC bifurcation latitude (SBL). Their dynamical mechanisms are then examined based on the Time‐Dependent Island Rule for the first time. It is shown that interannual anomalies of the SBL as well as the NEMC and SEMC transports are predominantly a response to the anomalous inflow from the ocean interior that is determined by the meridional interior transport. This, in turn, is a result of westward propagating Rossby waves induced by wind stress curl anomalies mainly in 60°E–90°E. The above mechanism is contrasted with that of the seasonal variation, where the local transport driven by wind stress around the island plays a role. Furthermore, the interannual variations of the SBL and the NEMC and SEMC transports are significantly correlated with the Niño 3.4 index with 5–15 months lag. It is suggested that diabatic heating anomalies associated with the El Niño/Southern Oscillation (ENSO) along with a local process in the southeastern Indian Ocean may generate wind stress curl anomalies over the southern Indian Ocean.
The compressed state Kalman filter for nonlinear state estimation: Application to large‐scale reservoir monitoring

Published: December 2015

AbstractReservoir monitoring aims to provide snapshots of reservoir conditions and their uncertainties to assist operation management and risk analysis. These snapshots may contain millions of state variables, e.g., pressures and saturations, which can be estimated by assimilating data in real time using the Kalman filter (KF). However, the KF has a computational cost that scales quadratically with the number of unknowns, m, due to the cost of computing and storing the covariance and Jacobian matrices, along with their products. The compressed state Kalman filter (CSKF) adapts the KF for solving large‐scale monitoring problems. The CSKF uses N preselected orthogonal bases to compute an accurate rank‐N approximation of the covariance that is close to the optimal spectral approximation given by SVD. The CSKF has a computational cost that scales linearly in m and uses an efficient matrix‐free approach that propagates uncertainties using N + 1 forward model evaluations, where
. Here we present a generalized CSKF algorithm for nonlinear state estimation problems such as CO2 monitoring. For simultaneous estimation of multiple types of state variables, the algorithm allows selecting bases that represent the variability of each state type. Through synthetic numerical experiments of CO2 monitoring, we show that the CSKF can reproduce the Kalman gain accurately even for large compression ratios (m/N). For a given computational cost, the CSKF uses a robust and flexible compression scheme that gives more reliable uncertainty estimates than the ensemble Kalman filter, which may display loss of ensemble variability leading to suboptimal uncertainty estimates.
Practical notes on local data‐worth analysis
Authors: Finsterle Stefan 
Published: December 2015

AbstractThese notes discuss the usefulness, limitations, and potential pitfalls of using sensitivity indices as a means to evaluate data worth and to guide the formulation and solution of inverse problems. A sensitivity analysis examines changes in model output variables with respect to changes in model input parameters. It appears straightforward to use this information to select influential parameters that should be subjected to estimation by inverse modeling and to identify the observations that contain information about these parameters and thus may be useful as calibration points. However, the results of such a sensitivity analysis do not account for parameter correlations and redundancies in observations and may not properly separate between calibration and prediction targets if used as criteria that guide inverse modeling; they may thus yield misleading recommendations about parameter identifiability and data worth. These issues (and some remedies) are discussed using an illustrative example, in which we examine the value of data sets potentially used for the calibration of a geothermal reservoir model. These notes highlight the importance of carefully formulating the objectives of a simulation study, which controls the setup of the inverse problem and related data needs.
Large wood transport and jam formation in a series of flume experiments
Authors: Davidson S. L. , MacKenzie L. G. , Eaton B.C. 
Published: December 2015

AbstractLarge wood has historically been removed from streams, resulting in the depletion of in‐stream wood in waterways worldwide. As wood increases morphological and hydraulic complexity, the addition of large wood is commonly employed as a means to rehabilitate in‐stream habitat. At present, however, the scientific understanding of wood mobilization and transport is incomplete. This paper presents results from a series of four flume experiments in which wood was added to a reach to investigate the piece and reach characteristics that determine wood stability and transport, as well as the time scale required for newly recruited wood to self‐organize into stable jams. Our results show that wood transitions from a randomly distributed newly recruited state to a self‐organized, or jam‐stabilized state, over the course of a single bankfull flow event. Statistical analyses of piece mobility during this transitional period indicate that piece irregularities, especially rootwads, dictate the stability of individual wood pieces; rootwad presence or absence accounts for up to 80% of the variance explained by linear regression models for transport distance. Furthermore, small pieces containing rootwads are especially stable. Large ramped pieces provide nuclei for the formation of persistent wood jams, and the frequency of these pieces in the reach impacts the travel distance of mobile wood. This research shows that the simulation of realistic wood dynamics is possible using a simplified physical model, and also has management implications, as it suggests that randomly added wood may organize into persistent, stable jams, and characterizes the time scale for this transition.

Published: December 2015

AbstractThe assembly of metal–organic frameworks (MOFs) into microcapsules has attracted great interest because of their unique properties. However, it remains a challenge to obtain MOF microcapsules with size selectivity at the molecular scale. In this report, we used cell walls from natural biomaterials as non‐toxic, stable, and inexpensive support materials to assemble MOF/cell wall (CW) microcapsules with size‐selective permeability. By making use of the hollow structure, small pores, and high density of heterogeneous nucleation sites of the cell walls, uniform and continuous MOF layers could be easily obtained by inside/outside interfacial crystallization. The prepared MOF/CW microcapsules have excellent stability and enable the steady, slow, and size‐selective release of small molecules. Moreover, the size selectivity of the microcapsules can be adjusted by changing the type of deposited MOF.

Published: December 2015

AbstractTau protein and its fragments self‐assemble into amyloid fibrils in the presence of polyanions, such as heparin. By combining microscopy, scattering, and spectroscopy techniques, we studied the aggregation of the 26‐mer Tau‐derived peptide alone, Tau306–327, the third repeat fragment (R3) of the microtubule‐binding domain. We show that: i) the sole Tau306–327 can self‐assemble into amyloid fibrils without the need of aggregation‐promoting polyanions; ii) the resulting structures consist of surprisingly large, well‐ordered 2D laminated flat ribbons, with a log‐normal distribution of the lateral width, reaching the unprecedented lateral size of 350 nm and/or 45 individual protofilaments, that is, the largest amyloid laminated structures ever observed for Tau or any other amyloidogenic sequence. Our results provide insight into the molecular determinants of Tau aggregation and open new perspectives in the understanding of the assembly of amyloid fibrils and β‐sheet‐based biomaterials.
Dynamic Inversion of Stereoselective Phosphate Binding to a Bisurea Receptor Controlled by Light and Heat
Authors: Vlatković Matea , Feringa Ben L. , Wezenberg Sander J. 
Published: December 2015

AbstractA chiral bisurea anion receptor, derived from a first‐generation molecular motor, can undergo photochemical and thermal isomerization operating as a reconfigurable system. The two possible cis configurations in the isomerization cycle are opposite in helicity, as is shown by CD spectroscopy. 1H NMR titrations demonstrate that the P and M helical cis isomers hold opposite enantioselectivity in the binding of binol phosphate, while anion complexation by the intermediate trans isomer is not selective. The difference in the binding affinity of the enantiomers was rationalized by DFT calculations, revealing very distinct binding modes. Thus, the enantiopreferred substrate binding in this receptor can be inverted in a dynamic fashion using light and heat.
Biomimetic Superhydrophobic/Superoleophilic Highly Fluorinated Graphene Oxide and ZIF‐8 Composites for Oil–Water Separation

Published: December 2015

AbstractSuperhydrophobic/superoleophilic composites HFGO@ZIF‐8 have been prepared from highly fluorinated graphene oxide (HFGO) and the nanocrystalline zeolite imidazole framework ZIF‐8. The structure‐directing and coordination‐modulating properties of HFGO allow for the selective nucleation of ZIF‐8 nanoparticles at the graphene surface oxygen functionalities. This results in localized nucleation and size‐controlled ZIF‐8 nanocrystals intercalated in between HFGO layers. The composite microstructure features fluoride groups bonded at the graphene. Self‐assembly of a unique micro‐mesoporous architecture is achieved, where the micropores originate from ZIF‐8 nanocrystals, while the functionalized mesopores arise from randomly organized HFGO layers separated by ZIF‐8 nanopillars. The hybrid material displays an exceptional high water contact angle of 162° and low oil contact angle of 0° and thus reveals very high sorption selectivity, fast kinetics, and good absorbencies for nonpolar/polar organic solvents and oils from water. Accordingly, Sponge@HFGO@ZIF‐8 composites are successfully utilized for oil–water separation.

Published: December 2015

AbstractA DNA‐based platform was developed to address fundamental aspects of early stages of cell signaling in living cells. By site‐directed sorting of differently encoded, protein‐decorated DNA origami structures on DNA microarrays, we combine the advantages of the bottom‐up self‐assembly of protein–DNA nanostructures and top‐down micropatterning of solid surfaces to create multiscale origami structures as interface for cells (MOSAIC). In a proof‐of‐principle, we use this technology to analyze the activation of epidermal growth factor (EGF) receptors in living MCF7 cells using DNA origami structures decorated on their surface with distinctive nanoscale arrangements of EGF ligand entities. MOSAIC holds the potential to present to adhered cells well‐defined arrangements of ligands with full control over their number, stoichiometry, and precise nanoscale orientation. It therefore promises novel applications in the life sciences, which cannot be tackled by conventional technologies.
