Prise de décision créative en situation d’incertitude : le cas de la sélection des mannequins par les maisons de mode1
Authors: Godart Frédéric , Mears Ashley
Published: July 2012

Face à l’existence d’une forte incertitude dans les industries dites « de la création », comment les producteurs culturels prennent-ils des décisions ? Nous abordons cette question en étudiant un cas particulier, la sélection des mannequins par les maisons de mode pour leurs défilés dans les villes de New York, Londres, Milan et Paris. Les données utilisées sont à la fois qualitatives (entretiens ethnographiques) et quantitatives (analyse de réseaux sociaux). Alors que les producteurs présentent la sélection des mannequins comme une question de « goût », ou de préférences personnelles, nous montrons que leurs décisions sont en fait définies par des mécanismes de partage de l’information dans des réseaux sociaux, notamment à travers des mécanismes d’« options ». L’analyse de nos données révèle que les processus décisionnels des producteurs culturels sont une question de choix stratégiques fondés sur le statut, même s’ils sont exprimés à travers une rhétorique du goût personnel.
Le culte de la minceur et la gestion sociale du risque : le cas de la Charte québécoise pour une image corporelle saine et diversifiée1
Authors: Baril Gérald , Paquette Marie-Claude , Gendreau Marcelle
Published: July 2012

Cet article examine le cas de laCharte québécoise pour une image corporelle saine et diversifiée.Le groupe de travail mis sur pied par le gouvernement du Québec en 2009 pour élaborer ladite charte était formé, en grande majorité, de représentants des industries de la mode et de l’image du corps. Les auteurs de l’article, inspirés par la sociologie du risque d’Ulrich Beck, centrent leur réflexion sur la motivation des acteurs de l’industrie à participer au processus et à s’engager en tant que signataires de la charte. Dans quelle mesure les acteurs de l’industrie acceptent-ils leur part de responsabilité, quant au risque représenté par la préoccupation excessive à l’égard du poids ? En s’appuyant notamment sur les propos recueillis auprès de membres du groupe de travail pour répondre à cette question, l’article fait ressortir la valeur intrinsèque du processus mené par le groupe, en tant qu’activité réflexive orientée vers l’action.
Quand les discours s’entrecroisent : « Sauvons le Montmartre bruxellois ! »
Authors: Hanquinet Laurie
Published: July 2012

En 2003, la dernière cité d’artistes bruxelloise, les Ateliers Mommen, était menacée par des promoteurs immobiliers. Cette affaire reçut une grande attention de la presse qui soutint véritablement les occupants. Comment expliquer un tel appui à des victimes de spéculation, comme il y en a d’autres ? Et pourquoi, malgré de nombreux arguments communs, les médias ne diffusèrent-ils pas les revendications des artistes autour de leurs droits ? L’article démontre, par l’analyse des discours de la presse et des artistes, que la sauvegarde des ateliers dépendit de leur pouvoir évocateur, renvoyant au mythe de l’artiste bohème. Les médias choisirent un « monde de justifications » basé sur « l’inspiration », qu’ils opposèrent au « monde marchand » des promoteurs (Boltanski et Thévenot, 1991). Cette grille de lecture ne laissa pas de place aux justifications civiques propres à la menace immobilière (déstructuration du tissu urbain) et aux droits des artistes (conditions de travail adaptées).
Éléments de polémique dans les manuels techniques d’assistance à la production de statistiques sociales pour le développement
Authors: Della Faille Dimitri
Published: July 2012

Les statistiques sociales occupent une place fondamentale dans les débats à l’égard des problèmes du sous-développement et justifient la mise en oeuvre de programmes pour remédier à ces mêmes problèmes. Ainsi, les organisations multilatérales ont un important besoin de statistiques pour mesurer, classer et comparer de multiples aspects de la vie sociale tels par exemple la santé, l’éducation et la pauvreté. Pour produire ces statistiques, elles s’appuient sur l’expertise d’agences nationales. Cet article explore les aspects polémiques d’un discours expert à partir de l’analyse d’un corpus récent d’une dizaine de manuels techniques produits par diverses organisations multilatérales telles que l’OCDE, la Banque mondiale, l’OMS, le PNUD et l’UNESCO. L’analyse de la représentation de la prise de décision, de la délibération, des débats, des controverses et des conflits révèle que ces manuels ne sont pas exempts de polémiques tant sur le plan méthodologique et scientifique que micro et macro politique.
Templated Assembly of pH‐Labile Polymer‐Drug Particles for Intracellular Drug Delivery
Authors: Cui Jiwei , Yan Yan , Wang Yajun , Caruso Frank
Published: July 2012

The preparation of pH‐labile polymer‐drug particles via mesoporous silica‐templated assembly for anticancer drug delivery into cancer cells is reported. The polymer‐drug conjugate is synthesized via thiol‐maleimide click chemistry using thiolated poly(methacrylic acid) (PMASH) and a pH‐labile doxorubicin (Dox) derivative. Drug‐loaded polymer particles that are stable under physiological conditions are obtained through infiltration of the conjugates into mesoporous silica particles, followed by cross‐linking the PMASH chains, and subsequent removal of the porous silica templates. The encapsulated Dox is released from the particles through cleavage of the hydrazone bonds between Dox and PMASH at endosomal/lysosomal pH. Cell viability assays show that the assembled PMASH particles have negligible cytotoxicity to LIM1899 human colorectal cancer cells. In comparison, Dox‐loaded PMASH particles cause significant cell death following internalization. The reported particles represent a novel and versatile class of stimuli‐responsive carriers for controlled drug delivery.
Wound‐Healing with Mechanically Robust and Biodegradable Hydrogel Fibers Loaded with Silver Nanoparticles
Authors: Neibert Kevin , Gopishetty Venkateshwarlu , Grigoryev Anton , Tokarev Ihor , Al‐Hajaj Noura , Vorstenbosch Joshua , Philip Anie , Minko Sergiy , Maysinger Dusica
Published: July 2012

The objective of this study is to provide a novel synthetic approach for the manufacture of wound‐healing materials using covalently cross‐linked alginate fibers loaded with silver nanoparticles. Alginate fibers are prepared by wet‐spinning in a CaCl2 precipitation bath. Using this same approach, calcium cross‐links in alginate fibers are replaced by chemical cross‐links that involve hydroxyl groups for subsequent cross‐linking by glutaraldehyde. The cross‐linked fibers become highly swollen in aqueous solution due to the presence of carboxyl functional groups, and retain their mechanical stability in physiological fluids owing to the stabilized network of covalent bonds. Alginate fibers can then be loaded with silver ions via the ion‐exchange reaction. Silver ions are reduced to yield 11 nm silver nanoparticles incorporated in the polymer gel. This method provides a convenient platform to incorporate silver nanoparticles into alginate fibers in controlled concentrations while retaining the mechanical and swelling properties of the alginate fibers. Our study suggests that the silver nanoparticles loaded fibers may be easily applied in a wound healing paradigm and promote the repair process though the promotion of fibroblast migration to the wound area, reduction of the inflammatory phase, and the increased epidermal thickness in the repaired wound area, thereby improving the overall quality and speed of healing.
Rapid Synthesis of Near Infrared Polymeric Micelles for Real‐Time Sentinel Lymph Node Imaging
Authors: Pan Dipanjan , Cai Xin , Kim Benjamin , Stacy Allen J. , Wang Lihong V. , Lanza Gregory M.
Published: July 2012

In this manuscript a synthetic methodology for developing sub 20 nm sized polymeric micellar nanoparticles designed for extravascular imaging and therapy is revealed. A simple, one‐pot method is followed, which involves a rapid co‐self‐assembly of an amphiphilic diblock copolymer (PS‐b‐PAA) and polyoxyethylene (80) sorbitan monooleate in water. Sorbitan monooleate imparts stability to the micelles and helps to drive down the particle size below 20 nm. The particles are incorporated with a water soluble dye ADS832WS, which absorbs in the near infrared range (λex = 832 nm) for sensitive detection with optical and photoacoustic imaging techniques. A candidate lipophilic anti‐angiogenic therapeutic agent fumagillin was also incorporated with high entrapment (>95%) efficiency. The effectiveness of this theranostic platform for real‐time, high‐resolution intraoperative photoacoustic imaging for facilitating direct assessment of the sentinel lymph nodes (SLN) in breast cancer staging is demonstrated. The technique offers huge potential providing faster resection of SLN and may minimize complications caused by axillary exploration due to mismarking with dyes or low‐resolution imaging techniques. Finally, the biodistribution and organ accumulation of the intravenously and intradermally injected particles are studied in a rodent model by optical imaging. Data suggest that intraveneously injected NIR‐polymeric nanoparticles follow a typical bio‐distribution clearance path through the reticuloendothelial (RES) system. For the intradermally injected particles, a slower mechanism of clearance is noticed.
Dimensionless performance and characteristic numbers of reverse flow diverters during reverse flow mode
Authors: Xu Cong , Yu Hui , Meng Xiangda
Published: July 2012

A reverse flow diverter (RFD) is a key fluidic component in RFD pumps, which are air‐powered, low‐maintenance devices used for transferring hazardous liquids. Despite several decades of practical application, no clear characteristic numbers exist for the suction ratio q = 1.0 and for the peak value of q, nor are there clear dimensionless performance curves for the reverse‐flow portion of the pumping cycle. We experimentally investigated the effects of suction gap length and nozzle exit diameter on RFD flow and pressure under the condition of diffuser entrance to nozzle exit area ratio of m = 1.0. The results were used to derive two dimensionless performance curves (q = A · exp[−δ/B] + C · exp[−δ/D] + E and q = k · α + F) and characteristic numbers at q = 1.0 and the peak value of q. These curves and numbers are useful to simplify the design program and ease the selection of operation parameters for RFD pumping systems. © 2012 Curtin University of Technology and John Wiley & Sons, Ltd.
Comparative Study of Trans‐Oral and Trans‐Tracheal Intratracheal Instillations in a Murine Model of Acute Lung Injury
Authors: Liu Ling , Gao Zhenping , Xia Changli , Xu Yanyan , Ma Zhongsen , Dong Chunling , Li Bo
Published: July 2012

Animal model is of importance to further elucidate the pathogenesis of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). We envisioned a possibility that there might be the differences in lipopolysaccharide (LPS)‐induced acute lung inflammation by the trans‐oral and trans‐tracheal intratracheal instillations. We compared the LPS‐induced early inflammatory responses by these two methods. The evaluative system included bronchoalveolar lavage (BAL) fluid biochemical analysis and differential cell counting, lung wet/dry weight ratio and lung histology. In vitro studies were performed on human bronchial epithelial cell line NCI‐H292 and alveolar Type II epithelial cell line A549 stimulated with LPS. Both interleukin (IL)‐8 release in the BAL fluid and IL‐8 secretions from NCI‐H292 and A549 cells were measured. We found that the trans‐tracheal intratracheal instillation promoted the LPS‐induced cell injury, neutrophil infiltration, and pulmonary edema compared to the trans‐oral one. The LPS‐induced pathological changes by the trans‐oral intratracheal instillation were characterized by pulmonary interstitial edema, but the trans‐tracheal intratracheal instillation was exudative pulmonary edema. More IL‐8 is produced from A549 cells than from NCI‐H292 cells under the treatment of LPS. The increased IL‐8 release in the BAL fluid and enhanced inflammatory responses caused by LPS may be due to more LPS delivered into the alveolar spaces by the trans‐tracheal intratracheal instillation compared to the trans‐oral one. The trans‐tracheal intratracheal instillation is proved to be more suitable to establish the murine model of ALI than the trans‐oral one and helpful to further elucidate the pathogenesis of ALI/ARDS.

Blast Furnace System Modeling by Multivariate Phase Space Reconstruction and Neural Networks
Authors: Luo Shihua , Gao Chuanhou , Zeng Jiusun , Huang Jian
Published: July 2012

Time series data collected from a medium‐size blast furnace (BF) is analyzed using the phase space reconstruction. To achieve better reconstruction, multivariate correlation analysis is first applied to screen out correlated variables, which shows that three important variables, i.e., silicon content in hot metal ([Si]), permeability index (FF), and coal injection (PM), are most appropriate for multivariate reconstruction. The time delay and embedding dimension are determined via the autocorrelation function and false nearest neighbor method. With the reconstructed time series, the neural networks model is applied to construct the predictive model for silicon content in hot metal. The simulation shows that the models based on multivariate reconstruction give better predictions than those obtained by univariate reconstruction. Moreover, it reveals that multivariate reconstruction can greatly mitigate the drawbacks caused by insufficiency of data.
Spectrofluorimetric determination of certain biologically active phenothiazines in commercial dosage forms and human plasma
Authors: Mohamed Abdel‐Maaboud I. , Abdelmageed Osama H. , Salem Hesham , Nagy Dalia M. , Omar Mahmoud A.
Published: July 2012

A validated simple and sensitive spectrofluorimetric method was developed for the determination of chlorpromazine hydrochloride, promethazine hydrochloride, trifluperazine hydrochloride, thioridazine hydrochloride, perazine maleate and oxomemazine. The method was based on condensation of malonic acid/acetic anhydride (MAA) under the catalytic effect of the tertiary amine moiety of the studied phenothiazines to provide a deep yellow to brown colour with green florescence. Relative fluorescence intensity of the products was measured at λexc 398 nm and λem 432 nm. Different variables affecting the reaction were studied and optimized. The method was successfully applied for the determination of the studied drugs in commercial dosage forms. The lower detection limits allowed the application of this method for the determination of the compounds in plasma as an example of a biological fluid. In addition, the method was considered specific for the determination of tertiary amines in the presence of primary and secondary amines; as a result, it was deemed suitable for the determination of the cited drugs in the presence of their degradation products resulting from N‐dealkylation or oxidation of the corresponding sulphoxides or sulphones.

Asociality and Engagement in Adult Offenders in Substance Abuse Treatment
Authors: Pankow Jennifer , Knight Kevin
Published: July 2012

In therapeutic community models for drug treatment, individual recovery is principally structured around group meetings and positive peer influences. Research shows that asocial group members with resistant behaviors and attitudes are at risk for poor treatment outcomes and have the potential to adversely impact the therapeutic group. To gain a better understanding of the asocial client's role in the larger treatment process, in‐prison treatment data were used: (1) to model and confirm a two‐factor solution of asociality consistent with the literature, and (2) to examine the relationship between asocial clients and treatment engagement for validation of the two‐factor model. Exploratory analysis resulted in a three‐factor solution representing behavioral responsivity, cognitive distortion, and social disassociation dimensions. Nested ANOVA (i.e., clients nested within prison programs) demonstrated that asocial levels (low, medium, and high risk) predicted treatment engagement. Furthermore, comparisons among asocial risk levels indicated that high asocial clients reported significantly lower engagement levels when compared with low and medium asocial clients.
