Published: May 2014

In this paper, the effects of porous bush elastic deformation on the static characteristics of finite porous journal bearing are investigated using Darcy’s law. The modified Reynolds equation applied to thermo-hydrodynamic problems is modified by considering the viscosity variation along the film thickness. The film pressure distribution and other characteristics such as the load carrying capacity and attitude angle are obtained by solving the governing equations numerically. Obtained results showed that deformation is considerable in the maximum pressure zone, and the elastic deformation will decrease the load carrying capacity. The viscosity variation parameter tends also to decrease the load carrying capacity.

Investigation of Energy Harvest Using a Piezoelectric Unimorph Post-Buckled by a Stretching Spring
Authors: Sun Sheng Fu , Dong Wei Jie , Cui Yan
Published: May 2014

Pre-stressed piezoelectric unimorphs show enhanced actuation displacements and high efficiency of energy harvesting compared with conventional unimorphs. A method to increase the amount of stored energy by injecting elastic energy to energy harvesting system consisting of the THUNDER device is described in this paper. A stretching spring is mounted on the two tabs of THUNDER device in order to inject energy to the system. The mechanical stress applied on THUNDER device results in an increase in the initial stored mechanical and elastic energy, which contribute to the improved response of the modified device. In experiment, two different springs were added on the THUNDER device: one's initial length is 17mm with k=45N/m and another is 33mm with k=145N/m. For the THUNDER device with a spring of k=145N/m and a proof mass of 8.2g, the maximum open circuit VRMS was 29.4V, and output power of 4.53mW was obtained by a load resistor of 90 kΩ at vibration frequency of 51Hz. Compared with standard device, the energy density or the output power at resonance frequency increased by 74.4%. The displacement performance of the modified devices was larger than that of the standard device. Through measurements and analysis, after a stretching spring was attached to the THUNDER device, dielectric constant did not change obviously, while d31 increased a lot. We can conclude that the improvement of energy harvesting is mainly due to the increase of d31 and stress distribution in the THUNDER device. Furthermore, the use of an initial energy injection mechanism based on a nonlinear approach can artificially enhance the conversion abilities of piezoelectric materials.

Authors: Weijs Cynthia A. , Coe Jason B. , Muise Amy , Christofides Emily , Desmarais Serge
Published: May 2014

From the Social media use by health professionals occurs in a digital environment where etiquette has yet to be solidly defined. The objectives of this study were to explore veterinarians’ personal use of Facebook, knowledge of privacy settings, and factors related to sharing personal information online. All American Animal Hospital Association member veterinarians with a valid e-mail address (9469) were invited to complete an online survey about Facebook (e.g., time spent on Facebook, awareness of consequences, types of information posted). Questions assessing personality dimensions including trust, popularity, self-esteem and professional identity were included. The response rate was 17% (1594 of 9469); 72% of respondents (1148 of 1594) had a personal Facebook profile. Veterinarians were more likely to share information on Facebook than they would in general. Trust, need for popularity, and more time spent on Facebook predicted more disclosure of personal information on Facebook. Awareness of consequences and increased veterinary experience predicted lesser disclosure. As veterinary practices use Facebook to improve client services, they need also to manage risks associated with online disclosure by staff. Raising awareness of reputation management and consequences of posting certain types of information to Facebook is integral to protecting the individual, the practice, and the veterinary profession.
Inside the Brachycephalic Nose: Conchal Regrowth and Mucosal Contact Points After Laser-Assisted Turbinectomy
Authors: Schuenemann Riccarda , Oechtering Gerhard
Published: May 2014

This prospective observational study analyzed conchal regrowth after laser-assisted turbinectomy (LATE) in brachycephalic dogs and the mucosal contact of regrown conchae. Eighty brachycephalic dogs (41 pugs, 39 French bulldogs [FBs]) that underwent LATE because of obstructing conchae were evaluated by endoscopy 7 days and 6 mo after surgery. At 6 mo, 96% of FBs’ and 65% of pugs’ nasal cavities showed regrowth of turbinates. FBs showed higher growth grades than pugs. Revision surgery because of reobstructing regrowth was required in the nasal cavities of 17% of FBs and 3% of pugs. The mean number of contact points reduced from 3.0 in FB and 1.7 in pugs before surgery to 1.2 in FB and 0.2 in pugs after conchal regrowth. Recollapse of nares after surgery significantly influenced the frequency of reoccurrence of contact points. LATE was proven to be an effective treatment of intranasal obstruction caused by mucosal contact between conchae. Conchal regrowth commonly occurs after surgical removal, but the new conchae cause less obstruction due to a significant reduction in number of contact points. Revision surgery because of reobstruction is rarely necessary. The important physiologic functions of conchae make nonobstructing regrowth desirable.
Programmes de mise au rancart volontaire de vieux véhicules et justice environnementale et distributionnelle : perspectives sur le volet québécois du programme fédéral Adieu Bazou
Authors: Lachapelle Ugo , Audette Alexis Pelletier
Published: May 2014

Les programmes de mise au rancart volontaire de vieux véhicules ont comme objectif principal la réduction des émissions polluantes par le retrait anticipé de véhicules automobiles polluants en encourageant leurs propriétaires à les recycler en échange d’incitatifs. Très peu d’analyses des retombées des programmes de mise au rancart sur les populations à faible revenu existent dans la littérature. Cet article propose d’établir un cadre de réflexion sur l’aspect distributionnel de la justice environnementale associé aux programmes de recyclage et explore le programme fédéral Adieu Bazou, en vigueur sur le territoire québécois entre 2009 et 2011. Bien que les vieux véhicules se trouvent fréquemment dans des zones à faible revenu, le taux de participation de ces populations à de tels programmes suggère qu’elles s’abstiennent d’y prendre part, par manque d’intérêt ou de capacité à utiliser les incitatifs proposés. Les organismes qui financent ces programmes gagneraient à s’assurer que les populations à faible revenu recyclent leurs vieux véhicules.

L’action locale à l’ère de la « glocalisation »
Authors: Gaudreau Louis
Published: May 2014

Cet article présente une réflexion sur l’essor du développement territorial intégré dans le champ de l’organisation communautaire. Il souligne les limites de cette pratique qui tiennent à sa conception réductrice du territoire se résumant à en faire le seul produit de l’interaction entre ses principaux groupes d’intérêt. La critique s’inspire de la tradition inaugurée par Henri Lefebvre dans le champ des études spatiales pour montrer que l’évolution d’un territoire est indissociable de celle que connaît la société dans son ensemble et donc, aujourd’hui, du développement du capitalisme sous sa forme néolibérale. Elle montre que l’émergence du développement territorial intégré participe, à certains égards, d’un processus de réarticulation entre le global et le local qui joue un rôle central dans la mise en place du projet néolibéral et qui limite l’organisation communautaire dans ses aspirations démocratiques au changement social. L’article se conclut par la brève présentation de deux principes alternatifs dont cette pratique pourrait s’inspirer.

Dans cet article, nous tentons de démontrer que la confiance interpersonnelle joue un rôle de médiation entre les réseaux sociaux et le comportement de partage des connaissances dans les entreprises tunisiennes de haute technologie. Même si l’impact direct des réseaux sociaux sur le partage des connaissances a été traité par les recherches antérieures, nous pensons qu’une telle relation gagnerait à intégrer le rôle de la confiance interpersonnelle comme mécanisme intermédiaire. En conformité avec McAllister (1995), nous nous proposons d’étudier deux formes de confiance interpersonnelle : la confiance cognitive (basée sur les compétences) et la confiance affective (basée sur les échanges socio-émotionnels). Un modèle structurel a permis de tester les hypothèses de recherche. Les résultats de l’enquête soutiennent partiellement nos conjectures théoriques. Ils montrent que seule la qualité des interactions dans un réseau social influence positivement et significativement les deux formes de confiance. Sur un autre plan, seule la confiance affective aurait une influence sur le comportement de partage des connaissances. Enfin, les résultats stipulent que la confiance affective médiatise l’effet de la qualité d’interaction sur le comportement de partage des connaissances. Une discussion est engagée sur la base de ces résultats et les implications de la recherche, sur le plan théorique et managérial, sont présentées.
Collective Regulation and Working Women in New Zealand and Fiji
Authors: Parker Jane , Arrowsmith James
Published: May 2014

In many nations, women’s labour market presence is significant though it tends to lag that of men on most indices, including pay and seniority. The ramifications of such are huge for women’s experience of employment, their circumstances in other spheres, and thus societal progress. Employment relations (ER) regulation seeks to structure equitable access to and progress within the labour market. However, despite on-going, work-related gender inequities, there is a relative dearth of cross-national (particularly South Pacific), gender-focused analyses. This constrains the development of theory and policy geared towards gender equality in the labour market.

This paper thus compares how recent collective ER regulatory initiatives have been applied in New Zealand (NZ) and Fiji, amid shared and unique national and international conditions. Martin and Bamber’s (2004, 2005) ER system model frames an analysis of qualitative survey responses and documentary evidence to more particularly assess the meaning of ER regulation for working women. It emerges that the achievement of gender equality via regulatory instruments has proven elusive, particularly in Fiji. A withering of formal employment regulation and its decentralisation in NZ; weakly implemented regulation in Fiji’s politically tumultuous setting; and the space left by a shift away from collective bargaining in both contexts has not been replaced by social dialogue, fundamental social rights, and in Fiji, regulatory enforcement. This has contributed to deteriorating circumstances for some working women in NZ and comparatively more in Fiji. However, informants showed a preference for certain regulatory measures for improving working women’s situation, concurring that stronger formal regulation of ER, tripartism and effective enforcement are needed in both nations, and that particular issues for working women require tailored responses.

The paper discusses how ER regulatory measures might be theorised in terms of improving working women’s context-bound circumstances in Fiji and NZ, and with regard to the infusion of gender-related and socio-cultural values in wider economic and political approaches. It also examines how regulatory initiatives might operate and impact in a more gender-sensitive way by being re-couched in ‘win-win’, inter-connected terms for different ER stakeholders. For Fiji, much hope also rests on its return to democratic rule, and for both countries, on strengthened union activity.
England’s “Bloody Code” in Crisis and Transition: Executions at the Old Bailey, 1760–1837
Authors: Devereaux Simon
Published: May 2014

The most celebrated and influential history of execution in England, V.A.C. Gatrell’s The Hanging Tree (Oxford, 1994), uses a survey of execution rates to make two very striking and seemingly persuasive assertions. First, more people were being hanged in early nineteenth-century England than at any time since the early modern era; and second, that the end of capital punishment came far more suddenly than previous studies have recognized. This article acknowledges and extends the importance of Gatrell’s first insight, while arguing that he nevertheless both understates the complexity of developments and overstates the suddenness with which both the letter and the practice of capital punishment were abandoned. It does so through a careful recalculation and analysis of execution rates at London’s Old Bailey courthouse, where execution was practiced on a far larger scale than in any other jurisdiction in the Anglo-American world, and whose practice most profoundly shaped the perceptions of both critics and proponents of capital punishment alike.
Immatérialité de la qualité et effet des labels sur le consentement à payer
Authors: Chameroy Fabienne , Veran Lucien
Published: May 2014

La question de l’immatériel est le plus souvent abordée par les sciences de gestion du point de vue des actifs gérables et des ressources internes mobilisables. Une autre approche existe qui consiste à considérer que la qualité finale du produit, telle que perçue par le consommateur, est un immatériel qui s’actualise dans des signes plus ou moins contrôlables par la firme. L’approche de la question de l’immatériel par le marché est ici construite à partir de la considération d’un attribut particulier de certains produits, le label et de son effet plus ou moins marqué sur le consentement à payer.

In the field of nanomedicine, nanoparticles with various functions are required for in vivo applications such as biomedical imaging and drug delivery. Therefore, chemical functionalization of nanoparticles has been extensively investigated. Herein, nanodiamond (ND) coated with polyglycerol (PG) and its derivatives is reported to impart good solubility in a physiological environment, a stealth nature to avoid nonspecific uptake, a targeting property to be taken up by a specific cell, and an acid‐responsive drug release property to kill cancer cells. ND is first grafted with PG and the resulting ND‐PG has a high solubility in physiological media. Since a large number of hydroxyl groups in PG provide scaffolds for further surface functionalization, the targeting RGD peptide and Pt‐based drug are immobilized to give ND‐PG‐RGD, ND‐PG‐Pt and ND‐PG‐RGD‐Pt. The ND with intrinsic fluorescence is also functionalized by PG and RGD to confirm cellular uptake and intracellular localization fluorescently. The results of the cell experiments indicate that PG coating shielded fND from the uptake by HeLa and U87MG cells. In contrast, fND‐PG‐RGD is taken up by U87MG, not HeLa cells, exhibiting high targeting efficacy. When ND‐PG‐RGD‐Pt is applied, U87MG is selectively killed against HeLa. The multi‐functional ND is a promising prodrug in targeting chemotherapy.
