Prise en charge thérapeutique : quand la référence au religieux soigne
Authors: Fournier Claude-Alexandre 
Published: January 2015

L’article est le fruit d’une étude exploratoire menée dans la partie francophone de la Suisse sur des prises en charge thérapeutiques dites « alternatives », notamment celles proposées par des rebouteux, magnétiseurs, médiums, néo-chamanes, etc. L’article débute par une description du champ couvert par ces prises en charge, champ compris dans un rapport de tension avec les champs de la santé physique, mentale et « spirituelle ». L’article se poursuit par l’analyse des différentes prises en charge considérées. Elle se fait au travers de l’étude du cadre thérapeutique et des processus qui s’y jouent. L’idée est de montrer comment la mobilisation d’une référence à une dimension religieuse permet un changement. L’analyse pose finalement la question du statut du praticien et de la référence religieuse qu’il mobilise.
Une relecture du cas Daniel Paul Schreber
Authors: Poupart Florent 
Published: January 2015

Nous proposons de relire les Mémoires d’un névropathe de Daniel Paul Schreber à la lumière du concept de psychose hystérique, défini comme une résolution psychotique de l’ambivalence hystérique à l’endroit du désir érotique de pénétration dans sa valence passive (la composante « vaginale » de la sexualité). Notre relecture nous amène à discuter les trois principales propositions du postulat freudien relatif à la psychose de Schreber, énoncé voilà un siècle : la nature homosexuelle du désir pathogène, le recours au mécanisme de la projection, et le diagnostic de paranoïa. Nous y confrontons une autre hypothèse, selon laquelle le délire de Schreber est de nature hystérique, et qu’il traduit la réalisation d’un désir prégénital de pénétration sans corps, qui se trouve aboli.

Published: January 2015

<p>With the implementation of 2010 World Health Organization guidelines, the number of infants from developing countries who will initiate antiretroviral therapy (ART) will increase considerably. In this study we describe the HIV antibody tests of 14 HIV infected children who initiated ART at age less than one year in a rural setting of India. The HIV rapid test was negative in seven and indeterminate in two cases, whereas the HIV enzyme-linked immunosorbent assay (ELISA) antibody test was negative in three and indeterminate in one case. In one child who had both negative HIV rapid test and ELISA initially, HIV serology turned positive after having a virological failure to ART, suggesting the possibility of utilizing HIV serology for monitoring ART effectiveness in children who experience HIV seroreversion. In conclusion, HIV seroreversion of children with early initiation of ART is common and should be considered for avoiding misdiagnosis of HIV infection.</p><p> </p>
Enhancing learning with the social media: student teachers’ perceptions on Twitter in a debate activity
Authors: Tur Gemma , Marín Victoria I. 
Published: January 2015

Abstract
This paper presents research focused on the educational experience of students using the microblogging platform Twitter for debate activities in three groups in different teacher education programmes at the University of the Balearic Islands, Spain. The implementation of this technology-based task in a face-to-face class was introduced as an innovative experience as a way of enhancing student learning and fostering participation in the context of formal learning. The educational objectives of these activities, besides working on the topics of the debate, were to empower student teachers’ Personal Learning Environments, engage student participation and enhance their use of social media and mobile devices for learning. Student perceptions were assessed by means of a questionnaire completed by them at the end of the courses. Tweets related to the debate were also collected in order to obtain some statistical data on student participation. Data collected allowed the researchers to observe student teacher engagement with the use of Twitter for the debate activity and its impact on their learning and understanding of the debate topic. Results also showed positive perceptions towards the use of social media in education and students’ willingness for future use, learning opportunities from Twitter and the use of mobile technology were also envisioned. Finally, conclusions argue the implications for practice of the current study and highlight some issues for further research, such as the exploration of new and innovative uses for teachers’ professional development and the empowerment of new activities and habits in learning on the move.
Analysis of risks in a Learning Management System: A case study in the Spanish National University of Distance Education (UNED)
Authors: Vázquez-Cano Esteban , Sevillano García M. Luisa 
Published: January 2015

Abstract
This article presents a research that examines the university students’ risk perception when using a Learning Management System called “aLF” and implemented by the Spanish National University of Distance Education (UNED) for the development of its university distance studies. The development of comprehensive Learning Management Systems for teaching-learning distance practices in the European Higher Education Area (EHEA) is a challenge for universities all around Europe. For this reason, it is necessary to analyze not only the benefits that involve these environments but the risks perceived by its users to improve teaching methods and design better user interfaces. Through a quantitative method, we test 588 students’ opinions about their risks perceptions when using this LMS to study the University degree in Pedagogy. Results show that main risks are concentrated in two dimensions: dimension 1 “basic or general” with high incidence of “fear of making mistakes” and “ignorance of the course content; and dimension 2 “own and beyond students’ circumstances” where it is important to stand out the risks not directly controlled by the students: “warning from the authorities for not developing the program”, “isolation from teachers” and “delegation of control”.
Determinants of Internet use for interactive learning: an exploratory study
Authors: Castaño Jonatan , Duart Josep M. , Sancho-Vinuesa Teresa 
Published: January 2015

Abstract
The use of the Internet in higher education teaching can facilitate the interactive learning process and thus improve educational outcomes. The aim of the study presented here is to explore which variables are linked to higher intensity of Internet-based interactive educational practices. The study is based on data obtained from an online survey of students from three different types of universities: a face-to-face university (University of Barcelona, UB), a technological face-to-face university (Universitat Politècnica de Catalunya. BarcelonaTech, UPC), and a virtual university (Open University of Catalonia, UOC). The data analysis shows that students who indicate high levels of benefit from Internet usage are those who use it most for interactive learning processes. It also shows the existence of other variables that, regardless of benefit, are linked to the intensity of Internet usage for interactive teaching-learning processes.
OIL SPILL RESPONSE PLANNING ON THE COLUMBIA RIVER ESTUARY
Authors: Christopherson Sharon K. , Slyman Paul M. 
Published: January 2015

ABSTRACT
The Columbia River Estuary lies along the Washington-Oregon state boundary on the west coast of the United States. The entire area is environmentally very sensitive with numerous large, shallow bays, exposed mud flats, wetland areas, and central channels having maximum currents of three to four knots. These features make the area very difficult to protect from an oil spill. Spill response is further complicated because of the many different state, federal, and local jurisdictions with mandated responsibilities in oil spill response and environmental protection.
Under the leadership of the U. S. Coast Guard Marine Safety Office in Portland, Oregon, a steering group was established to guide the development of a response plan for the Columbia River Estuary. A concerted effort was made to include representatives from response organizations, natural resource agencies, and resource users from federal, state, and local governments, and commercial sectors in the planning process. The first draft of an operational response plan was completed the summer of 1992 through a combination of technical workshops, field trips, and small working groups meeting with local communities. The Columbia River Estuary Response Plan prioritizes areas to protect; identifies specific response strategies for protecting these areas; and outlines the logistics needed to implement these strategies, including equipment needs, the location of staging areas, and the identification of pre-designated command posts. The local spill response cooperative and oil transportation industry are using the plan to coordinate the purchase of response equipment and the staging of this equipment at numerous locations along the river.
Key to the success of the plan is ensuring that all the groups responding to an event participate in the planning process together. This process has worked well for the Columbia River Estuary and will serve as a model for response planning for other environmentally sensitive areas along the Columbia River and coastal areas of Washington and Oregon.
Enhanced sensitivity of oceanic CO2 uptake to dust deposition by iron‐light colimitation
Authors: Nickelsen Levin , Oschlies Andreas 
Published: January 2015

AbstractThe iron hypothesis suggests that in large areas of the ocean phytoplankton growth and thus photosynthetic CO2 uptake is limited by the micronutrient iron. Phytoplankton requires iron in particular for nitrate uptake, light harvesting, and electron transport in photosynthesis, suggesting a tight coupling of iron and light limitation. One important source of iron to the open ocean is dust deposition. Previous global biogeochemical modeling studies have suggested a low sensitivity of oceanic CO2 uptake to changes in dust deposition. Here we show that this sensitivity is increased significantly when iron‐light colimitation, i.e., the impact of iron bioavailability on light‐harvesting capabilities, is explicitly considered. Accounting for iron‐light colimitation increases the shift of export production from tropical and subtropical regions to the higher latitudes of subpolar regions at high dust deposition and amplifies iron limitation at low dust deposition. Our results reemphasize the role of iron as a key limiting nutrient for phytoplankton.
Breakthrough curve moments scaling in hyporheic exchange
Authors: Bellin A. , Tonina D. , Marzadri A. 
Published: January 2015

AbstractThe interaction between stream flow and bed forms creates an uneven distribution of near‐bed energy heads, which is the driving force of hyporheic exchange. Owing to the large disparity of advection characteristic times in the stream and within the hyporheic zone, solute mass exchange is often modeled by considering the latter as an immobile region. In a recent contribution Gónzalez‐Pinzón et al. (2013) showed that existing models employing this hypothesis are structurally inconsistent with the scaling revealed by the analysis of 384 breakthrough curves collected in 44 streams across five continents. Motivated by this result, we analyze the scaling characteristics of a model that we recently developed by combining the analytical solution of the advective flow within the hyporheic zone with a Lagrangian solute transport model. Results show that similarly to the experimental data our model predicts breakthrough curves with a constant skewness, irrespective of the stream size, and that the scaling of the first three moments observed by Gónzalez‐Pinzón et al. (2013) is also respected. Moreover, we propose regression curves that relate the first three moments of the residence time distribution with the alternate bar dimensionless depth (
), a quantity that is easily measurable in the field. The connection between BTC moments and
opens new possibilities for modeling transport processes at the catchment scale.
Kontrollierte Freisetzung von verkapselten flüchtigen bioaktiven Verbindungen durch Brechen der Kapselwand als Folge einer lichtinduzierten Gasbildung
Authors: Paret Nicolas , Trachsel Alain , Berthier Damien L. , Herrmann Andreas 
Published: January 2015

AbstractDie Verkapselung lichtempfindlicher 2‐Oxoacetate in Mikrokapseln mit Kern‐Schale‐Struktur ermöglicht eine lichtinduzierte, kontrollierte Freisetzung biologisch aktiver Substanzen. Durch Bestrahlung mit UVA‐Licht zersetzen sich die verkapselten Oxoacetate und bilden einen Gasüberdruck im Inneren der Kapseln, der die Kapselwand ausdehnt oder zum Bersten bringt. Headspace‐Messungen bestätigten die lichtgesteuerte Bildung von CO und CO2 sowie die erfolgreiche Freisetzung der biologisch aktiven Substanz. Mittels optischer Mikroskopie konnten die Bildung von Gasblasen, das Aufbrechen der Kapselwand sowie das Austreten der verkapselten Ölphase beobachtet werden. Die Effizienz des Freisetzungssystems beruht auf der Struktur und der Menge des im Verhältnis zur Wandstärke verwendeten 2‐Oxoacetats und auf der Intensität des einstrahlenden UVA‐Lichtes.

Published: January 2015

AbstractA direct, facile, and highly diastereo‐ and enantioselective dearomatization reaction of β‐naphthol derivatives with aziridines has been developed for the first time. A newly designed Box–OH ligand was employed for an in situ generated magnesium catalyst and proved to be efficient. The corresponding dearomatization product was transformed into a polycyclic scaffold and polyhydroxylated compound. 1H NMR studies revealed the activation mode of the dearomatization process of β‐naphthols, and a clear positive nonlinear effect was observed in the reaction, and provides insight into the coordination environment around the MgII center and the possible active species.

Published: January 2015

Abstract

Background
The use of postoperative complication rates to derive metrics such as failure-to-rescue (FTR) is of increasing interest in assessing the quality of care. The aim of this study was to quantify FTR rates for elective abdominal aortic aneurysm (AAA) repair in England using administrative data, and to examine its validity against case-note review.

Methods
A retrospective observational study using Hospital Episode Statistics (HES) data was combined with a multicentre audit of data quality. All elective AAA repairs done in England between 2005 and 2010 were identified. Postoperative complications were extracted, FTR rates quantified, and differences in FTR and in-hospital death rates established. A multicentre case-note review was performed to establish the accuracy of coding of complications, and the impact of inaccuracies on FTR rates derived from HES data.

Results
A total of 19 638 elective AAA repairs were identified from HES; the overall mortality rate was 4·6 per cent. Patients with complications (19·2 per cent) were more likely to die than those without complications (odds ratio 12·22, 95 per cent c.i. 10·51 to 14·21; P &lt; 0·001) and had longer hospital stays (P &lt; 0·001). FTR rates correlated strongly with death rates, whereas complication rates did not. On case-note review (661 procedures), 41·5 per cent of patients had a complication recorded in the case notes. There was evidence of systematic under-reporting of complications in HES, leading to an overall misclassification rate of 36·3 (95 per cent c.i. 33·7 to 39·2) per cent (P &lt; 0·001), which was less pronounced for surgical complications (12·6 (11·1 to 13·9) per cent; P &lt;0·001). Despite this, the majority of FTR rates derived from HES were not significantly different from those derived from case-note data.

Conclusion
Postoperative complication and FTR rates after elective AAA repair can be derived from HES data. However, use of the metric for interprovider comparisons should be done cautiously, and only with concurrent case-note validation given the degree of miscoding identified.
Synthesis of Lysozyme–Metallacarborane Conjugates and the Effect of Boron Cluster Modification on Protein Structure and Function
Authors: Kowalski Konrad , Goszczyński Tomasz , Leśnikowski Zbigniew J. , Boratyński Janusz 
Published: January 2015

AbstractTwo complementary methods, “in solution” and “in solid state”, for the synthesis of lysozyme modified with metallacarborane (cobalt bis(dicarbollide), Co(C2B9H11)22−) were developed. As metallacarborane donors, oxonium adducts of cobalt bis(dicarbollide) and 1,4‐dioxane or tetrahydropyran were used. The physicochemical and biochemical properties of the obtained lysozyme–metallacarborane conjugates were studied for changes in secondary and tertiary structure, aggregation behavior, and biological activity. Only minor changes in primary, secondary, and tertiary protein structure were observed, caused by the single substitution of metallacarborane on lysozyme. However, the modification produced significant changes in lysozyme enzymatic activity and a tendency toward time‐ and temperature‐dependent aggregation.

BackgroundEndomyocardial biopsy constitutes an essential part of the diagnostic algorithm in patients with heart failure of unknown origin, but usually requires transfemoral access.Methods and ResultsHere, we describe a novel method that allows interventional cardiologists to obtain left ventricular biopsies via transradial access with a 7.5F sheathless multipurpose (MP1.0) guiding catheter. This approach was successfully conducted in 37 consecutive patients at our institution with only one intraprocedural minor complication (ventricular fibrillation during insertion of the guiding catheter).ConclusionsTransradial access to obtain left ventricular endomyocardial biopsies is a feasible and safe option for experienced radial operators. © 2015 Wiley Periodicals, Inc.
An Alkene‐Promoted Borane‐Catalyzed Highly Stereoselective Hydrogenation of Alkynes to Give Z‐ and E‐Alkenes
Authors: Liu Yongbing , Hu Lianrui , Chen Hui , Du Haifeng 
Published: January 2015

AbstractThe stereoselective hydrogenation of alkynes to alkenes is an extremely useful transformation in synthetic chemistry. Despite numerous reports for the synthesis of Z‐alkenes, the hydrogenation of alkynes to give E‐alkenes is still not well resolved. In particular, selective preparation of both Z‐ and E‐alkenes by the same catalytic hydrogenation system using molecular H2 has rarely been reported. In this paper, a novel strategy of using simple alkenes as promoters for the HB(C6F5)2‐catalyzed metal‐free hydrogenation of alkynes was adopted. Significantly, both Z‐ and E‐alkenes can be furnished by hydrogenation with molecular H2 in high yields with excellent stereoselectivities. Further experimental and theoretical mechanistic studies suggest that interactions between H and F atoms of the alkene promoter, borane intermediate, and H2 play an essential role in promoting the hydrogenolysis reaction.

Practical Synthesis of anti‐β‐Hydroxy‐α‐Amino Acids by PdII‐Catalyzed Sequential C(sp3)H Functionalization

Published: January 2015

AbstractAn improved and practical procedure for the stereoselective synthesis of anti‐β‐hydroxy‐α‐amino acids (anti‐βhAAs), by palladium‐catalyzed sequential C(sp3)H functionalization directed by 8‐aminoquinoline auxiliary, is described. followed by a previously established monoarylation and/or alkylation of the β‐methyl C(sp3)H of alanine derivative, β‐acetoxylation of both alkylic and benzylic methylene C(sp3)H bonds affords various anti‐β‐hydroxy‐α‐amino acid derivatives. As an example, the synthesis of β‐mercapto‐α‐amino acids, which are highly important to the extension of native chemical ligation chemistry beyond cysteine, is described. The synthetic potential of this protocol is further demonstrated by the synthesis of diverse β‐branched α‐amino acids. The observed diastereoselectivities are strongly influenced by electronic effects of aromatic AAs and steric effects of the linear side‐chain AAs, which could be explained by the competition of intramolecular COAc bond reductive elimination from PdIV intermediates vs. intermolecular attack by an external nucleophile (AcO−) in an SN2‐type process.
Fullerene–Ionic‐Liquid Conjugates: A New Class of Hybrid Materials with Unprecedented Properties

Published: January 2015

AbstractA modular approach has been followed for the synthesis of a series of fullerene–ionic‐liquid (IL) hybrids in which the number of IL moieties (two or twelve), anion, and cation have been varied. The combination of C60 and IL give rise to new unique properties in the conjugates such as solubility in water, which was higher than 800 mg mL−1 in several cases. In addition, one of the C60–IL hybrids has been employed for the immobilization of palladium nanoparticles through ion exchange followed by reduction with sodium borohydride. Surprisingly, during the reduction several carbon nanostructures were formed that comprised nano‐onions and nanocages with few‐layer graphene sidewalls, which have been characterized by means of thermogravimetric analysis (TGA), X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), scanning electron microscopy/energy‐dispersive X‐ray analysis (SEM‐EDAX), and high‐resolution transmission electron microscopy (HRTEM). Finally, the material thus obtained was successfully applied as catalyst in Suzuki and Mizoroki–Heck reactions in a concentration of just 0.2 mol %. In the former process it was recyclable for five runs with no loss in activity.
