Un roman dont il n’y a rien à dire
Authors: Arseneau Isabelle 
Published: September 2017

L’examen comparé des manuscrits qui ont conservé le roman de Méraugis de Portlesguez de Raoul de Houdenc (v. 1225-1235) tend à suggérer qu’il y aurait autant de versions de cette oeuvre qu’il y a de copies. Dans le manuscrit de Vienne ÖN 2599 – un livre du second quart du xive siècle qui se distingue fortement de la tradition manuscrite des romans arthuriens en vers par sa facture (un luxe rare) et sa composition (une oeuvre unique) –, les variantes sont à ce point nombreuses que leur collationnement semble témoigner de la volonté de proposer un roman différent de celui conservé dans les recueils du Vatican (Reg. Lat. 1725) et de Turin (BUN, L.IV 33). Les interventions du scribe visent autant le texte que le péritexte : s’il corrige le style, la thématique et le dispositif narratologique disloqués que l’on associe à l’écriture de Raoul de Houdenc, il propose également un prologue et un programme iconographique qui réorientent le roman vers le didactisme plutôt que vers le divertissement, visée qui était classiquement la sienne. Dépouillé de sa dimension contestataire (antiromanesque), le roman obtenu à force d’ajustements qui trahissent l’oeuvre telle qu’elle a été conservée dans les autres codices semble fournir un exemple de rupture entre la sphère du roman critique (destiné au plaisir intellectuel des clercs) et celle du roman « plaisant » (destiné plutôt à l’usage de la cour).
ACADEMIC LEADERSHIP IN THE CONTEXT OF NEOLIBERALISM
Authors: Barnoff Lisa , Moffatt Ken , Todd Sarah , Panitch Melanie 
Published: September 2017

Driven by neoliberal principles, new managerialist demands for austerity and accountability are reshaping the practices of directors of Canadian schools of social work. In this paper, we discuss research that aimed to clarify how directors of social-justice-oriented social work schools engage in academic leadership in the context of new managerialism. We were especially interested to know how this engagement affects them. Our data come from five interviews and one focus group with five directors of schools of social work in Canada. Four themes emerged from the data: directors’ fight for resources; directors as agents for resource management; directors as ‘buffers’ to shield their faculty from stresses associated with resource cuts; and resistance through relationship-building. Pushed to act as resource managers, directors’ efforts are largely unknown and sometimes unappreciated by faculty members. Our findings will be useful to professional schools negotiating their future in the university system, especially at a time when social work faculties struggle to motivate individuals to take on leadership roles. Overall, the findings of this study help clarify the nature of leadership practices in schools of social work, contributing to a better understanding of the current situation, the requirements of leadership, and how to support leadership.
L’évaluation de l’employabilité au sein du régime québécois d’aide sociale
Authors: Provencher Ysabel 
Published: September 2017

Le présent article est issu des résultats d’une recherche documentaire financée par le Centre de recherche sur les politiques en matière d’invalidité professionnelle (CRPIP) et portant sur les processus et instruments de mesure de l’invalidité mis en application dans différents domaines des services publics. S’inscrivant dans le champ du Implementation Research, cette recherche rend compte de l’état des connaissances au sujet des instruments et modalités d’évaluation des capacités de travail tels qu’appliqués dans les régimes d’assistance publique, dont celui du Québec. Nous présentons ici quelques-uns des résultats de cette recherche portant sur les caractéristiques du processus d’évaluation de l’employabilité du régime québécois d’assistance publique (aide sociale).
L’évaluation de l’employabilité renvoie à l’identification des limites et des obstacles à l’emploi avec lesquels sont aux prises les individus assistés. Au Québec, ce processus suit deux filières parallèles; 1- l’évaluation des contraintes liées à l’état de santé, fondée sur le caractère permanent ou non de la limitation et 2- l’investigation des autres obstacles/limitations à l’emploi. Cette seconde filière se déploie dans le cadre de l’entrevue d’évaluation et d’aide à l’emploi (SAEE) en fonction d’une liste préétablie d’obstacles liés à quatre domaines de compétences. L’examen effectué montre que l’évaluation des incapacités lies à la santé est effectuée dans une optique de vérification d’éligibilité à une allocation ou un programme de soutien financier tandis que l’évaluation des autres incapacités est effectuée dans une optique de détermination d’un plan de services visant à favoriser le renforcement de la capacité d’insertion durable en emploi du demandeur d’assistance.

Published: September 2017

Cet article présente les résultats d’une étude, de nature qualitative et exploratoire, effectuée dans le cadre théorique des représentations sociales. Il a pour objectifs de : 1) documenter, au moyen d’images, la représentation qu’ont les hommes gais de l’homosexualité masculine en société et 2) comprendre comment ces images façonnent les orientations et les modalités d’intervention souhaitées par les hommes gais. Dix entretiens semi-dirigés ont été menés auprès d’hommes s’identifiant comme gais, âgés de 22 à 54 ans, principalement caucasiens, de différents états civils et niveaux de scolarité. L’analyse inductive de contenu a mis en relief la présence de cinq images de l’homosexualité masculine produites par le processus représentationnel d’objectivation : a) la normalité; b) la flamboyance; c) la vulnérabilité; d) la déviance; e) l’hypersexualisation. Les interventions souhaitées par les répondants visent surtout des changements dans le sens du renforcement de la seule image perçue favorablement, celle de la normalité. L’article suggère que les interventions doivent plutôt viser le changement des représentations sociales à l’origine des images négatives de l’homosexualité masculine afin de cultiver le respect envers tous les hommes gais, et non pas seulement envers ceux qui se conforment au modèle hétéronormatif.
Investigating Spatial Interdependence in E-Bike Choice Using Spatially Autoregressive Model
Authors: Xu Chengcheng , Wang Chen , Wang Wei , Bao Jie , Yang Menglin 
Published: September 2017

Increased attention has been given to promoting e-bike usage in recent years. However, the research gap still exists in understanding the effects of spatial interdependence on e-bike choice. This study investigated how spatial interdependence affected the e-bike choice. The Moran’s I statistic test showed that spatial interdependence exists in e-bike choice at aggregated level. Bayesian spatial autoregressive logistic analyses were then used to investigate the spatial interdependence at individual level. Separate models were developed for commuting and non-commuting trips. The factors affecting e-bike choice are different between commuting and non-commuting trips. Spatial interdependence exists at both origin and destination sides of commuting and non-commuting trips. Travellers are more likely to choose e-bikes if their neighbours at the trip origin and destination also travel by e-bikes. And the magnitude of this spatial interdependence is different across various traffic analysis zones. The results suggest that, without considering spatial interdependence, the traditional methods may have biased estimation results and make systematic forecasting errors.
Cranial sexual dimorphism in the Kinda baboon (Papio hamadryas kindae)
Authors: Singleton Michelle , Seitelman Brielle C. , Krecioch Joseph R. , Frost Stephen R. 
Published: September 2017

AbstractObjectivesThe smallest extant member of genus Papio, the Kinda baboon exhibits low sexual dimorphism and a distinctive cranial shape. Ontogenetic scaling accounts for most cranial‐shape differences within Papio, but studies have shown that the Kinda follows a separate ontogenetic trajectory. If so, its cranial‐dimorphism pattern should differ from other subspecies. To evaluate this hypothesis, morphometric analysis was used to investigate cranial dimorphism in Papio.Materials and methodsThree‐dimensional landmarks were digitized on 434 adult crania representing six Papio subspecies. Size‐ and shape‐dimorphism magnitudes were quantified using centroid size and Procrustes distances. Patterns of sex‐ and size‐related variation were explored using MAN(C)OVA, multivariate regression, and form‐space PCA. Canine dimorphism was investigated using dental metrics.ResultsKinda size and shape dimorphism are significantly lower than in other Papio subspecies. The relative magnitude of Kinda shape dimorphism is similar to other southern baboons; Kinda canine dimorphism is unremarkable. MAN(C)OVA results support subspecies differences in cranial dimorphism and scaling. Allometric and dimorphism vectors differ significantly in some subspecies, and their vector‐angle matrices are strongly correlated. The Kinda's allometric vector angles are divergent. Form‐space PC3, summarizing size‐independent dimorphism, separates the Kinda from other subspecies.DiscussionThe Kinda baboon exhibits significantly lower size and shape dimorphism than other baboons, but its relative dimorphism levels are unexceptional. The Kinda differs from other subspecies in patterns of allometry, size‐related shape dimorphism, and residual shape dimorphism. Kinda facial shape is “masculinized” relative to size, especially in females, suggesting female sexual selection contributed to the evolution of Kinda dimorphism.
The First Zero‐Length Mass Spectrometry‐Cleavable Cross‐Linker for Protein Structure Analysis
Authors: Hage Christoph , Iacobucci Claudio , Rehkamp Anne , Arlt Christian , Sinz Andrea 
Published: September 2017

AbstractCombining the properties of a zero‐length cross‐linker with cleavability by tandem mass spectrometry (MS/MS) poses great advantages for protein structure analysis using the cross‐linking/MS approach. These include a reliable, automated data analysis and the possibility to obtain short‐distance information of protein 3D‐structures. We introduce 1,1′‐carbonyldiimidazole (CDI) as an easy‐to‐use and commercially available, low‐cost reagent that ideally fulfils these features. CDI bridges primary amines and hydroxy groups in proteins with the lowest possible spacer length of one carbonyl unit (ca. 2.6 Å). The cross‐linking reaction can be conducted under physiological conditions in the pH range between 7.2 and 8. Urea and carbamate cross‐linked products are cleaved upon collisional activation during MS/MS experiments generating characteristic product ions, greatly improving the unambiguous identification of cross‐links. Our innovative analytical concept is exemplified and applied for bovine serum albumin (BSA), wild‐type tumor suppressor p53, an intrinsically disordered protein, and retinal guanylyl cyclase activating protein‐2 (GCAP‐2).
La‐modified vermiculites for efficient adsorption of Congo red
Authors: Huang Wei‐Ya , Yu Changlin , Li Dan 
Published: September 2017

AbstractIn this study, we utilized lanthanum to modify vermiculite (RV) targeting at high dye removal and superior reusability. La‐modified RV materials were synthesized; followed by detailed characterizations and adsorption studies. Compared with the BET surface area (SBET) of RV (2.98 m2·g−1), those of La‐modified RV samples were increased by up to 8 times. Their adsorption performances were investigated by employing Congo red (CR) as the target pollutant in aqueous solution. An increasing loading of La in RV led to enhanced CR removal capacity. The experimental equilibrium data of the La‐modified RV were fitted better by using the Freundlich model than the Langmuir model. At the same initial concentration of 100 mg·L−1, the equilibrium capacity of CR was 32.3–80.5 mg·g−1 using the La‐modified RV adsorbents, which was 2.5–7.8 times greater than that using RV (9.1 mg·g−1). Meanwhile, the adsorption kinetics was analysed by the pseudo‐first‐order, pseudo‐second‐order and intra‐particle diffusion models; the kinetics followed the pseudo‐second‐order model best and the intra‐particle diffusion was not the only rate limiting step during adsorption. Superior adsorption capacity of LaRV‐0.2, which possessed 29.93 wt% La loading, was observed in the pH range of 3–9; especially the high removal rate (~94%) was observed when pH = 3. The removal rate was increased to ~96.8% in the presence of NaCl compared with 91.6% in the absence of NaCl. The as‐synthesized adsorbent maintained a superior adsorption capacity after four adsorption–desorption cycles. The capacity of the regenerated adsorbent in the fourth adsorption–desorption cycle was only 4.2% lower than that of the fresh LaRV‐0.2 sample, suggesting great potential in practical wastewater treatment. © 2017 Curtin University and John Wiley & Sons, Ltd.
The diminished stakeholder: Examining the relationship between suppliers and supermarkets in the Australian grocery industry
Authors: Grimmer Louise 
Published: September 2017

AbstractThis study examines the role of stakeholders in the context of the retail industry, specifically the Australian supermarket industry. Through the lens of stakeholder theory, it is argued that suppliers to the Australian supermarket duopoly (Coles and Woolworths) might be considered “diminished” stakeholders, that is, they lack in urgency, legitimacy, and power. Using a case study methodology, this study analyses two separate cases of Coles and Woolworths' treatment of suppliers during the period 2011 and 2014. In the two cases, Australian Federal Court proceedings were brought by the Australian Competition and Consumer Commission against both supermarkets for “unconscionable” behaviour towards their suppliers. The study also examines the impact of the relationship between Coles and Woolworths and their suppliers on consumers as the end‐user in the chain of consumption. The paper argues that the ethical treatment of suppliers by supermarkets will lead to better outcomes for both suppliers and consumers and contribute to the long‐term sustainability of the firm.

Published: September 2017

AbstractS‐(+)‐Methyl 2‐(2‐chlorophenyl)‐2‐(6,7‐dihydrothieno[3,2‐c]pyridin‐5(4H)‐yl)acetate, also known as (S)‐clopidogrel, is marketed under the trade names Plavix and Iscover. It is a potent thienopyridine‐class of antithrombotic and antiplatelet drug (antiaggregant). Among the two available stereoisomers of clopidogrel, for pharmaceutical activities only the S‐enantiomer is applicable, as no antithrombotic activity is observed in the R‐enantiomer and causes political upheavals and social turmoil in animal experiments. Worldwide sales of Plavix amounted to $6.4 billion yearly, which ranks second. Attributed to the increased demand of (S)‐clopidogrel drug, it provoked the synthetic community to devise facile synthetic approaches. This review aims to summarize the synthetic methods of (S)‐clopidogrel drug reported in the literature. The present review discusses the pros and cons of each synthetic methodology, which would be beneficial to the scientific community for further developments in the synthetic methodologies for (S)‐clopidogrel. In addition, the compilation approach of literature‐reported synthetic strategies of (S)‐clopidogrel in one platform is advantageous, supportive, and crucial for the synthetic community to elect the best synthetic methodology of (S)‐clopidogrel and to create new synthesis ideas.
A wide range delay locked loop for low power and low jitter applications
Authors: Estebsari Motahhareh , Gholami Mohammad , Ghahramanpour Mohammad Javad 
Published: September 2017

SummaryIn this paper, a design of analog delay locked loop is introduced in which new techniques are applied to eventually increase operating frequency range and reduce jitter considerably. In this design, all blocks of a delay locked loop including a voltage controlled delay line, charge pump, and loop filter are accurately designed. A new delay cell is proposed with wide delay range, in which increase of delay range results in using fewer cells, and consequently the power consumption will decrease. Current mirror techniques and feedback in the proposed charge pump also cause higher current matching and better jitter performance. This delay locked loop, which is designed with TSMC 0.18‐μm CMOS technology, has a wide frequency range from 217 to 800 MHz. It consumes maximum 3.4‐mW and minimum 2.6‐mW power dissipation in source voltage of 1.8 V, which is suitable for low power applications. It also has an appropriate lock time that is at least equal to 3 clock cycles at 217 MHz and at most 25 clock cycles at 800 MHz. Jitter performance in this delay locked loop is improved significantly: RMS jitter is 0.65 ps at 800 MHz and 2.54 ps at 217 MHz. Moreover, its maximum peak‐to‐peak jitter is equal to 5.17 ps, and its minimum peak‐to‐peak jitter is equal to 1.39 ps at 217 and 800 MHz, respectively.

SummaryThe canonical Wnt signalling pathway has been implicated in organogenesis and self‐renewal of essentially all stem cell systems. In vivo reporter systems are crucial to assess the role of Wnt signalling in the biology and pathology of stem cell systems. We set out to develop a Turquoise (TQ) fluorescent protein based Wnt reporter. We used a CRISPR‐Cas9 approach to insert a TQ fluorescent protein encoding gene into the general Wnt target gene Axin2, thereby establishing a Wnt reporter mouse similar to previously generated Wnt reporter mice but with the mTurquoise2 gene instead of E. coli‐β‐galactosidase (LacZ). The use of mTurquoise2 is especially important in organ systems in which cells need to a be alive for further experimentation such as in vitro activation or transplantation studies. We here report successful generation of Axin2‐TQ mice and show that cells from these mice faithfully respond to Wnt signals. High Wnt signals were detected in the intestinal crypts, a classical Wnt signalling site in vivo, and by flow cytometry in the thymus. These mice are an improved tool to further elucidate the role of Wnt signalling in vivo.
Thermal plasticity in postembryonic life history traits of a widely distributed Collembola: Effects of macroclimate and microhabitat on genotypic differences
Authors: Sengupta Sagnik , Ergon Torbjørn , Leinaas Hans Petter 
Published: September 2017

AbstractLife history traits in many ectotherms show complex patterns of variation among conspecific populations sampled along wide latitudinal or climatic gradients. However, few studies have assessed whether these patterns can be explained better by thermal reaction norms of multiple life history traits, covering major aspects of the life cycle. In this study, we compared five populations of a Holarctic, numerically dominant soil microarthropod species,Folsomia quadrioculata, sampled from a wide latitudinal gradient (56–81°N), for growth, development, fecundity, and survival across four temperatures (10, 15, 20, and 25°C) in common garden experiments. We evaluated the extent to which macroclimate could explain differences in thermal adaptation and life history strategies among populations. The common garden experiments revealed large genotypic differences among populations in all the traits, which were little explained by latitude and macroclimate. In addition, the life history strategies (traits combined) hardly revealed any systematic difference related to latitude and macroclimate. The overall performance of the northernmost population from the most stochastic microclimate and the southernmost population, which remains active throughout the year, was least sensitive to the temperature treatments. In contrast, performance of the population from the most predictable microclimate peaked within a narrow temperature range (around 15°C). Our findings revealed limited support for macroclimate‐based predictions, and indicated that local soil habitat conditions related to predictability and seasonality might have considerable influence on the evolution of life history strategies ofF. quadrioculata. This study highlights the need to combine knowledge on microhabitat characteristics, and demography, with findings from common garden experiments, for identifying the key drivers of life history evolution across large spatial scales, and wide climate gradients. We believe that similar approaches may substantially improve the understanding of adaptation in many terrestrial ectotherms with low dispersal ability.

AbstractConflicting evidence has been provided as to whether induction of intestinal inflammation by adoptive transfer of naïve T cells into Rag−/− mice requires expression of the transcription factor T‑bet by the T cells. Here, we formally show that the intestinal microbiota composition of the Rag−/− recipient determines whether or not T‐bet‐deficient Th cells can induce colitis and we have resolved the differences of the two microbiomes, permissive or non‐permissive to T‐bet‐independent colitis. Our data highlight the dominance of the microbiota over particular T cell differentiation programs in the pathogenesis of chronic intestinal inflammation.
