Les articulations famille-travail à l’aune du groupe professionnel et du genre : l’exemple des conductrices de train en France
Authors: Bonnet Estelle , Milly Bruno , Verley Élise 
Published: March 2013

Comment les conductrices de train gèrent-elles en France l’articulation entre travail et famille au regard des conditions et rythmes de travail spécifiques qui pèsent sur le groupe professionnel? Si les normes professionnelles, associées à une faible régulation organisationnelle, interdisent de demander des aménagements de services en raison de contraintes « familiales », la récente politique de féminisation de ce « bastion masculin » conduit à une réinterrogation de ces pratiques. Les nouvelles conductrices ne demandent pas d’aménagements spécifiques, leur présence soulève toutefois la question de l’articulation travail/famille, qui jusque-là était sinon taboue, du moins reléguée au rang de contrainte professionnelle incontournable et laissée à la charge des seuls professionnels.
Devenir adulte : le rapport à la religion dans la construction identitaire des jeunes de la diaspora palestinienne au Canada
Authors: Gaudet Stéphanie , Hird-Younger Miriam , Thériault Marie-Andrée , Thibeault Karine 
Published: March 2013

Dans cet article, les auteurs explorent le rapport à la religion dans la construction identitaire des jeunes adultes de la diaspora palestinienne canadienne. En sociologie de la jeunesse, peu de recherches s’intéressent au rapport à la religion des jeunes au cours du processus d’entrée dans l’âge adulte. Pourtant, la religion occupe un rôle important dans la vie de plusieurs jeunes, notamment celle de jeunes immigrants. Nos résultats préliminaires suggèrent que si ces jeunes expérimentent l’injonction à « répondre de soi » que vivent les autres jeunes des sociétés post-industrielles, s’ajoute pour eux une négociation avec les aspects culturels et cultuels de la religion dans leur construction identitaire.
« Être un vrai orthodoxe ». L’identité religieuse au carrefour des registres d’authenticité
Authors: Moisa Daniela 
Published: March 2013

Une analyse ethnographique de la sémantique pratique et discursive de l’authenticité religieuse révèle que la définition du « vrai orthodoxe » chez les immigrants russes établis au Québec dépasse les frontières du religieux. Elle est traversée par des références culturelles, spatiales, linguistiques, familiales ou encore politiques, qui s’avèrent essentielles dans l’affirmation de l’identité religieuse orthodoxe. Ces registres d’authenticité jouent un rôle essentiel dans le fonctionnement des communautés culturelles immigrantes de même que dans les rapports entre les groupes religieux et culturels différents. Ils stabilisent aussi l’identité fragilisée par la migration, en aidant les Russes orthodoxes à délimiter et à fonder dans le pays d’accueil, des lieux qui leur sont propres – orthodoxes et russes –, mais qui sont aussi reconnus et respectés par les orthodoxes d’autres origines culturelles, par les convertis ou par une majorité catholique.
Has There Been a She-covery? The Financial Crisis of 2008 and Its Impact on the Ontario Labour Market
Authors: Lewchuk Wayne 
Published: March 2013

The labour market turmoil associated with the financial crisis that began in late 2008 provides an opportunity to test the effect of the feminization of labour markets on how modern labour markets function in times of crisis (Armstrong, 1996; Vosko, 2000; Korkki, 2011). This paper will focus on two related questions. The first is whether men and women had different experiences as labour markets began to recover in November 2010. The second is whether the standard employment contract, that implies that workers with more seniority will be offered a degree of employment security in exchange for loyalty to a company, has frayed.These questions are explored by comparing the pre- and post-financial crisis labour market outcomes of 791 individuals employed in an area centred on Toronto and bounded by Hamilton in the west and Oshawa in the east. Evidence is presented on changes in having paid employment, the degree of employment security, the form of the employment relationship, and the characteristics of the employment relationship. Study participants completed a detailed survey describing their employment in June 2005 and again in November 2010. The paper assesses the accuracy of reports that suggest that the quality of employment had returned to pre-financial crisis levels by the spring of 2011 (Tal, 2011; Cross, 2011).The findings suggest there has been a gendered dimension to the post-financial crisis recovery in labour markets. However, the nature of this effect is not as simple as women finding more secure, better paying employment, or men being forced into less secure employment. For the sample as a whole, men were marginally more likely than women to be in paid employment. Young men were the most successful in finding more secure employment. Middle-aged men were the most likely to remain in paid employment in the post-financial crisis labour market, but at the cost of accepting less secure employment and employment that was less likely to have the characteristics of the standard employment relationship.

IntroductionShifting HIV treatment tasks from physicians to nurses and midwives is essential to scaling‐up HIV services in sub‐Saharan Africa. Updating nursing and midwifery regulations to include task shifting and pre‐service education reform can help facilitate reaching new HIV targets. Donor‐supported initiatives to update nursing and midwifery regulations are increasing. However, there are gaps in our knowledge of current practice and education regulations and a lack of information to target and implement regulation strengthening efforts. We conducted a survey of national nursing and midwifery councils to describe current nursing and midwifery regulations in 13 African countries.MethodsA 30‐item survey was administered to a convenience sample of 13 national nursing and midwifery regulatory body leaders in attendance at the PEPFAR‐supported African Health Profession Regulatory Collaborative meeting in Nairobi, Kenya on 28 February, 2011. The survey contained questions on task shifting and regulations such as registration, licensure, scope of practice, pre‐service education accreditation, continuing professional development and use of international guidelines. Survey data were analyzed to present country‐level, comparative and regional findings.ResultsTask shifting to nurses and midwives was reported in 11 of the 13 countries. Eight countries updated their scope of practice within the last five years; only one reported their regulations to reflect task shifting. Countries vary with regard to licensure, pre‐service accreditation and continuing professional development regulations in place. There was no consistency in terms of what standards were used to design national practice and education regulations.DiscussionMany opportunities exist to assist countries to modernise regulations to incorporate important advancements from task shifting and pre‐service reform. Appropriate, revised regulations can help sustain successful health workforce strategies and contribute to further scale‐up HIV services and other global health priorities.ConclusionsThis study provides fundamental information from which to articulate goals and to measure the impact of regulation strengthening efforts.
The use of learning in fast adaptation algorithms
Authors: Cooper John , Che Jiaxing , Cao Chengyu 
Published: March 2013

SUMMARYRecently, an adaptive control algorithm was proposed to handle time‐varying parameters with transient characterization. Using fast and robust adaptation, the unknown time‐varying parameters are no longer restricted to having slow change rates. As unknown nonlinear functions can be simply expressed by a few time‐varying parameters, they can be handled by the adaptive framework easily without resorting to learning techniques such as artificial neural networks. This motivates a fundamental question about whether learning is still useful in algorithms using fast adaptation. This paper provides an answer to this question. An adaptive controller is presented that uses a radial basis function neural network in addition to the currently used piecewise constant adaptive law of the algorithm to approximate uncertainties. Even though the fast and robust adaptation of control can handle unknown nonlinear functions, there is still an advantage to using neural networks. This advantage is that certain design parameters related to the adaptation rate can be relaxed while still achieving good performance. It is shown that performance improves with better function approximation, and the inclusion of the neural network in the control architecture cannot degrade performance but only improve it. Fast adaptation requires a small integration step size. In the presence of artificial neural network learning, the same performance can be achieved at a lower adaptation rate or enlarged integration step size. This benefit is important for practical implementation of fast adaptation algorithms by relaxing the often stringent constraints on hardware CPU speed. Theoretical results are supported by simulations. Copyright © 2013 John Wiley & Sons, Ltd.

Authors: Jayaraman Jayakumar , Wong Hai Ming , King Nigel , Roberts Graham 
Published: March 2013

ABSTRACTObjectivesThis investigation aimed to evaluate the secular trend exhibited by developing permanent teeth in 5 to 6 years old southern Chinese children.MethodsFour hundred radiographs of children born in the years 1981 (n=200) and 2001 (n=200) were randomly selected, and then age and gender matched. Maxillary and mandibular teeth on the left side were scored. The number of tooth developmental stages (n‐tds) for each stage of development and total n‐tds in crown and root development was calculated. Logistic regression, X2 test for occurrence of trend and Fisher's exact test were used to evaluate the variations in n‐tds between crown and root maturation and also maturation among different teeth. Dental maturation between boys and girls was also compared.ResultsIn the maxillary dentition, children born in 2001 showed advanced dental maturation (odds ratio, 1.29; P=0.001), and girls exhibited earlier maturation than boys (odds ratio, 1.43; P=0.001). In the mandibular dentition, no significant difference between the years was observed (odds ratio, 0.97; P=0.761), however, girls showed accelerated development than boys (odds ratio, 1.26; P=0.002). Variations in maturation were also observed between individual tooth in the same arch and between the arches.ConclusionsChildren born in 2001 demonstrated accelerated dental development only in the maxillary dentition. Girls born in 1981 and 2001 exhibited advanced maturation than boys. Variations in development among different teeth in the year groups indicate the need for inclusion of all developing teeth to establish a secular change. Am. J. Hum.

Synthesis and Pharmacology of Proteasome Inhibitors
Authors: Rentsch Andreas , Landsberg Dirk , Brodmann Tobias , Bülow Leila , Girbig Anna‐Katharina , Kalesse Markus 
Published: March 2013

AbstractShortly after the discovery of the proteasome it was proposed that inhibitors could stabilize proteins which ultimately would trigger apoptosis in tumor cells. The essential questions were whether small molecules would be able to inhibit the proteasome without generating prohibitive side effects and how one would derive these compounds. Fortunately, “Mother Nature” has generated a wide variety of natural products that provide distinct selectivities and specificities. The chemical synthesis of these natural products finally provided access to analogues and optimized drugs of which two different classes have been approved for the treatment of malignancies. Despite these achievements, additional lead structures derived from nature are under investigation and will be discussed with regard to their biological potential and chemical challenges.

Published: March 2013

ObjectiveTo quantitatively evaluate the position, size, and shape of the menisci in subjects with radiographic knee osteoarthritis (OA) compared to subjects without OA, using magnetic resonance imaging (MRI).MethodsWe studied the right knees of 39 Osteoarthritis Initiative participants (24 women and 15 men with a mean age of 59.6 ± 8.7 years) with medial compartment radiographic tibiofemoral OA (Kellgren/Lawrence grade of 2 or 3). Subjects were matched individually for age, sex, and height to controls without knee OA and without risk factors for knee OA. The right knees of the controls were used as references. One observer performed manual segmentation of the tibial plateau and the medial and lateral meniscus based on a coronally reconstructed double‐echo steady‐state sequence with water excitation, focusing on 5 central 3T MRIs.ResultsIn OA knees, there was less meniscal coverage of the medial tibial plateau (435 mm2 versus 515 mm2; P = 0.0004), the medial meniscus body showed more extrusion (2.64 mm versus 0.53 mm; P < 0.0001), and the peripheral margin had a more convex shape, i.e., bulged more (mean 0.61 mm versus 0.27 mm; P < 0.0001). The thickness or volume of the medial meniscus body of OA knees did not differ substantially from reference knees. In contrast, in OA knees the lateral meniscus body had a larger volume (mean 266 mm3 versus 224 mm3; P = 0.0005) and extruded more (mean 1.16 mm versus −1.01 mm; P < 0.0001), and the external margin bulged more (mean 0.53 mm versus 0.35 mm; P < 0.0001), than in reference knees.ConclusionOur findings indicate altered meniscal position and shape (i.e., more bulging) in both compartments in medial compartment knee OA. These changes may be important features of OA pathogenesis and/or disease consequences.

Authors: Erucar Ilknur , Yilmaz Gamze , Keskin Seda 
Published: March 2013

AbstractMixed matrix membranes (MMMs) combine easy processability and low cost of polymers with the high selectivity of nanoporous filler particles. These membranes represent an important avenue for enhancing the performance of polymeric membranes in gas separations. Recently, a new group of nanoporous materials called metal–organic frameworks (MOFs) have been used as filler particles in MMM applications, and significant improvements in gas selectivity and permeability have been reported for these MOF‐based membranes. We discuss the recent developments in MOF‐based MMMs by reviewing both the experimental studies and computational modeling methods that can accelerate selection of MOF/polymer combinations for high‐performance gas separations.

Published: March 2013

ABSTRACTThe bioluminescence system (luciferase reporter assay system) is widely used to study gene expression, signal transduction and other cellular activities. Although transfection of reporter plasmid DNA to mammalian cell lines is an indispensable experimental step, the transfection efficiency of DNA varies among cell lines, and several cell lines are not suitable for this type of assay because of the low transfection efficiency. In this study, we confirm the transfection efficiency of reporter DNA to several cancer and normal cell lines after transient transfection by single‐cell imaging. Luminescence images could be obtained from living single cells after transient transfection, and the calculated transfection efficiency of this method was similar to that of the conventional reporter assay using a luminometer. We attempted to measure the activity of the Bip promoter under endoplasmic reticulum stress conditions using both high and low transfection efficiency cells for plasmid DNA at the single‐cell level, and observed activation of this promoter even in cells with the lowest transfection efficiency. These results show that bioluminescence imaging of single cells is a powerful tool for the analysis of gene expression based on a reporter assay using limited samples such as clinical specimens or cells from primary culture, and could provide additional information compared with the conventional assay.

Published: March 2013

ABSTRACT22‐[N(−7‐Nitrobenz‐2‐oxa‐1,3‐diazol‐4‐yl)amino]‐23,24‐bisnor‐5‐cholen‐3β‐ol (NBD‐cholesterol), a fluorescent cholesterol analog, was an extragenous cholesterol tracer used to study cholesterol absorption and metabolism in cultured cells. In order to measure free intracellular cholesterol and its esters, a precise and sensitive method employing high‐performance liquid chromatography/fluorescence detection (HPLC‐FLD) was developed for the first time. Method validation showed a limit of detection at 30 ng/mL. The calibration curve was linear within the range of 0.0625–10.0 µg/mL (r2 = 0.999). Accuracy and precision were highlighted by good recovery and low variations. Apart from NBD‐cholesteryl oleate, two additional cellular metabolites of NBD‐cholesterol, probably an isomer and an oxidation product, were determined in the lipid extracts of Caco‐2 human colon adenocarcinoma cells according to mass spectrometry. In AC29 mouse malignant mesothelioma cells overexpressing acyl‐CoA:cholesterol acyltransferase‐1 (ACAT1) or ACAT2, only the oxidized metabolite was detected. Using the newly developed method, YIC‐C8‐434, a known ACAT inhibitor, was shown to inhibit ACAT activity in Caco‐2 cells, as well as in AC29/ACAT1 or AC29/ACAT2 cells. In conclusion, the sensitive and specific HPLC‐FLD method is a powerful tool for simultaneous quantification of intracellular NBD‐cholesterol and its oleoyl‐ester.

Dye Degradation by Layer‐by‐Layer Immobilised Peroxidase/Redox Mediator Systems
Authors: Saladino Raffaele , Guazzaroni Melissa , Crestini Claudia , Crucianelli Marcello 
Published: March 2013

AbstractHorseradish peroxidase (HRP) was immobilised on Eupergit C 250 L resin coated with poly‐electrolytes, or by entrapment inside pre‐formed layer‐by‐layer (LbL) micro‐capsules of poly‐electrolytes. In these systems, namely HRP/E‐LbL, HRPm/LbL and HRPm/LbLp, the native enzyme retained its catalytic activity. Immobilised HRP showed a significant activity in the oxidation of selected azo, quinoline and fluorone dyes with H2O2 as the primary oxidant under mild experimental conditions, and HRPm/LbL was the best catalyst. A comparison between the catalytic efficiency of different redox mediators for HRP activity was made by using 1‐hydroxybenzotriazole (HOBt), violuric acid (VLA) and veratrylic alcohol (VA). As a general trend, azo dyes were degraded in higher yields, and HOBt was the best mediator for the oxidation. The degradation yield increased on increasing the reaction time and reached the highest value after 12 h, which is comparable with that observed for native HRP. Notably, HRPm/LbL retained its catalytic activity for more runs.

Published: March 2013

AbstractAddressing the underdeveloped area of the interrelationships between institutional logics, organizational legitimacy, and organizational identity, we undertake a critical hermeneutic analysis of the archives of the Administrative Sciences Association of Canada (ASAC) and the context in which the association exists. Through our analysis we show how ASAC's response to the conflicting institutional logics of Canadianism and business schools has been one of internal cohesion, with continuous attempts to create collaborative synergies between the logics, rather than succumbing to internal conflict and fragmentation.
