Moi, c’est l’Autre. L’histoire des Franco-Américains dans la culture populaire télévisuelle et cinématographique au Québec (1949-1992)1
Authors: Lavoie Pierre 
Published: July 2018

Dans cet article, l’auteur propose de mettre à profit l’historiographie existante et des sources télévisuelles et cinématographiques populaires, telles qu’Entre chien et loup et Les Tisserands du pouvoir, pour analyser les représentations de l’histoire des migrations canadiennes-françaises en Nouvelle-Angleterre au Québec après la Seconde Guerre mondiale. Il appert qu’après avoir progressivement développé une identification collective distincte au cours du siècle des grandes migrations (1840-1930), les Franco-Américains ont été dépossédés symboliquement de cette distinction par l’appropriation de leur histoire dans le cadre des conflits linguistiques et identitaires du Québec de la fin des années 1980.

Les usages des technologies numériques dans la sphère politique constituent un objet de recherche largement investi en science politique, cependant en langue anglaise plus qu’en français. Ce numéro spécial dePolitique et Sociétéss’emploie à rétablir l’équilibre, en présentant et en mettant en perspective les résultats d’un projet comparatif franco-québécois sur les campagnes en ligne,enpolitique.com. L’introduction propose une synthèse de la littérature universitaire concernant trois domaines : les usages du web et des médias sociaux comme outils de campagne électorale, la constitution d’équipes spécialisées dans la communication politique numérique, et les appropriations des dispositifs de campagne par des citoyens, sociologiquement spécifiques, et politisés. L’introduction présente aussi une synthèse des résultats français et québécois discutés dans le numéro, qui montrent que l’expansion des technologies numériques ne fait pas disparaître les logiques antérieures de structuration de la compétition électorale. En revanche, elle conduit à des réaménagements importants des activités de communication politique.
Relever le défi de l’hybridité

Published: July 2018

Cet article examine les objectifs stratégiques assignés aux campagnes électorales en ligne dans le discours de membres des équipes de campagne de l’élection présidentielle française et de l’élection générale québécoise (toutes deux en 2012). L’analyse est menée à partir de 37 entretiens semi-directifs réalisés avec différents types de personnels de campagne au Québec et en France. En mobilisant le concept d’hybridité des campagnes électorales, les objectifs stratégiques de campagne tels qu’ils ressortent des entretiens sont divisés en trois catégories : objectifs de diffusion de contenus ; objectifs politiques et de mobilisation ; objectifs de marketing et d’animation de communautés. L’analyse indique que les objectifs de diffusion de contenus liés à la dissémination et au contrôle des messages sont les plus souvent mentionnés. Également, des différences contextuelles apparaissent. D’abord, le Québec est la démocratie où les discours sur la diffusion de contenus, et dans une moindre mesure le marketing et l’animation, sont les plus dominants, tandis que les objectifs politiques et de mobilisation sont plus souvent évoqués en France. Ensuite, il ressort que les stratèges de gauche sont plus enclins à insister sur les objectifs politiques et de mobilisation, alors que les stratèges de droite sont plus axés sur la diffusion de contenus. Troisièmement, le discours des équipes des candidats et partis au pouvoir se distingue par une attention accrue à la diffusion de contenus, notamment au contrôle du message, contrairement à celui des opposants. L’étude conclut que tous les partis ont mené des campagnes hybrides au sein desquelles le numérique est une composante centrale. Elle rappelle également qu’il convient de prendre en compte les facteurs institutionnels afin de mieux comprendre les différences en termes de campagnes en ligne d’une démocratie à l’autre.
Militer sur Internet ou militer à (bonne) distance du parti
Authors: Theviot Anaïs 
Published: July 2018

Cet article propose d’analyser les reconfigurations du militantisme au prisme du numérique, par une analyse « au microscope » de trajectoires individuelles, afin de saisir finement la réalité des pratiques militantes derrière les discours d’institution, les injonctions partisanes et les perceptions mythifiées. Notre enquête se centre ainsi sur les récits de vie de deux (ex-)adhérents du Parti socialiste dans un contexte localisé – la Fédération de Gironde – pour retranscrire de façon processuelle et à long terme les motifs de dés/engagement mis en avant. Nous verrons que militer en ligne peut être considéré à la fois comme une forme de reconversion, une réponse à un « moment critique » dans la trajectoire des adhérents et une occasion de faire carrière en politique. En somme, il s’agit de militer à bonne distance du parti, que ce soit pour s’y fondre ou s’en éloigner.
Quantifying construction vibration effects on daily radiotherapy treatments
Authors: Hindmarsh Jonathan J. , Smith Wendy L. 
Published: July 2018

AbstractThe existing two‐story parkade is being replaced by a four‐story parkade on a hospital campus. The parkade is across a two‐lane access road from a cancer center with a nine‐linear accelerator radiotherapy department in the basement. The new parkade is supported by over 280 drilled and cased pilings installed at depths between 10 and 25 m depending on the underlying soil strata and varying diameters, up to 1.5 m. The construction work in such close proximity to the radiation therapy department resulted in significant vibrations being felt in the simulation and treatment vaults. The amplitude and frequency of the vibration was measured. Using vendor supplied documentation, the total vibratory amplitude of the linear accelerators in use within the department was calculated. The results fell outside of specification, resulting in changes to the way the project preceded following discussion with the project management team.

AbstractObjectiveStudies using conventional full‐field visual evoked potentials (ffVEP) have reported subtle abnormalities in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). We hypothesize that these abnormalities can be detected in the majority of CIDP patients using enhanced methods.MethodsWe performed a cross‐sectional noninterventional study comparing 18 CIDP patients and 18 matched healthy controls using multifocal VEP (mfVEP) as a technique with enhanced sensitivity to detect conduction abnormalities across the spectrum of optic nerve fibers. Patients with confounding diseases (ophthalmologic, diabetes mellitus) were excluded.ResultsThe mean amplitude and latency, as well as the low‐contrast visual acuity, did not differ between CIDP patients and controls. Subanalyses revealed latency differences concerning the superior sector of the visual field. Severity markers of CIDP (ODSS, motor nerve conduction velocity) were associated with mfVEP latency delay.InterpretationWe could not adduce evidence for clinically or diagnostically relevant visual pathway involvement in CIDP. The latency differences identified were very subtle and restricted to the superior visual field which cannot be readily explained biologically, anatomically, or pathologically. In summary, we conclude that our study revealed no relevant differences in mfVEP parameters between CIDP patients and controls.

AbstractLiver transplantation is the most effective treatment for patients with end‐stage liver diseases, but hepatocyte transplantation using spheroids is expected to become an alternative strategy owing to the limited number of liver donors. However, the effects of the transplantation route and spheroid size on cell dynamics and the organ‐specific accumulation of hepatocytes are not well characterized. In this study, the influence of three delivery routes (tail vein, portal vein, and spleen) and three spheroid sizes (50, 100, and 150 µm in diameter) on the accumulation of human fetal hepatocytes labeled with quantum dots in the liver and other organs (heart, lung, kidney, and spleen) of recipient mice is investigated. Ex vivo fluorescence imaging reveals that the accumulation of transplanted cells in the liver is highest for transplantation via the portal vein compared with other routes. The accumulation efficiency depends on spheroid size, and spheroids with a diameter of 50 µm display greater accumulation than that of spheroids of other sizes. It is concluded that hepatocyte transplantation via the portal vein using small spheroids of 50 µm in diameter may be effective for clinical applications.

AbstractThe negative differential resistance (NDR) effect observed in conducting polymer/Au nanoparticle composite devices is not yet fully clarified due to the random and disordered incorporation of Au nanoparticles into conducting polymers. It remains a formidable challenge to achieve the sequential arrangement of various components in an optimal manner during the fabrication of Au nanoparticle/conducting polymer composite devices. Here, a novel strategy for fabricating Au nanoparticle/conducting polymer composite devices based on self‐assembled Au@PPy core–shell nanoparticle arrays is demonstrated. The interval between the two Au nanoparticles can be precisely programmed by modulating the thickness of the shell and the size of the core. Programmable NDR is achieved by regulating the spacer between two Au nanoparticles. In addition, the Au/conducting polymer composite device exhibits a reproducible memory effect with read–write–erase characteristics. The sequentially controllable assembly of Au@PPy core–shell nanoparticle arrays between two microelectrodes will simplify nanodevice fabrication and will provide a profound impact on the development of new approaches for Au/conducting polymer composite devices.

Published: July 2018

AbstractOptical interference is used to enhance light–matter interaction and harvest broadband light in ultrathin semiconductor absorber films on specular back‐reflectors. However, the high‐temperature processing in oxygen atmosphere required for oxide absorbers often degrades metallic back‐reflectors and their specular reflectance. In order to overcome this problem, a newly developed film flip and transfer process is presented that enables high‐temperature processing without degradation of the metallic back‐reflector and without the need of passivation interlayers. The film flip and transfer process improves the performance of photoanodes for photoelectrochemical water splitting comprising ultrathin (<20 nm) hematite (α‐Fe2O3) films on silver–gold alloy (90 at% Ag–10 at% Au) back‐reflectors. Specular back‐reflectors are obtained with high reflectance below hematite films, which is necessary for maximizing the productive light absorption in the hematite film and minimizing nonproductive absorption in the back‐reflector. Furthermore, the film flip and transfer process opens up a new route to attach thin film stacks onto a wide range of substrates including flexible or temperature sensitive materials.

Published: July 2018

AbstractWater scarcity is one of the most alarming problems of the planet. An ambient ion based method is developed to make hydrophilic‐hydrophobic patterned silver nanowires (NWs) as humidity harvesters of unprecedented efficiency. Such water harvesters are developed by two‐step surface modification of the as‐synthesized NWs (known from a report earlier) using electrospray. These patterned NWs of ≈20 µm length and ≈200 nm width grown over a relatively large area (2 × 2 cm2) exhibit atmospheric water capture (AWC) efficiency of 56.6 L m−2 d−1, the highest reported so far. The whole fabrication process of the surface is performed under ambient conditions with a home‐built nanoelectrospray ion source, without the help of any sophisticated instrumentation. The synthesized material combines and mimics two exciting examples of AWC in nature, which are cactae and Namib Desert beetles, which utilize AWC for their living. It is believed that the combination of the special features of the above two natural species helps to achieve the highest water capture efficiency reported till date. A working prototype using this surface for AWC is also fabricated.

AbstractSodium‐ion batteries are widely regarded as a promising supplement for lithium‐ion battery technology. However, it still suffers from some challenges, including low energy/power density and unsatisfactory cycling stability. Here, a cross‐linked graphene‐caged Na3V2(PO4)2F3 microcubes (NVPF@rGO) composite via a one‐pot hydrothermal strategy followed by freeze drying and heat treatment is reported. As a cathode for a sodium‐ion half‐cell, the NVPF@rGO delivers excellent cycling stability and rate capability, as well as good low temperature adaptability. The structural evolution during the repeated Na+ extraction/insertion and Na ions diffusion kinetics in the NVPF@rGO electrode are investigated. Importantly, a practicable sodium‐ion full‐cell is constructed using a NVPF@rGO cathode and a N‐doped carbon anode, which delivers outstanding cycling stability (95.1% capacity retention over 400 cycles at 10 C), as well as an exceptionally high energy density (291 Wh kg−1 at power density of 192 W kg−1). Such micro‐/nanoscale design and engineering strategies, as well as deeper understanding of the ion diffusion kinetics, may also be used to explore other micro‐/nanostructure materials to boost the performance of energy storage devices.
Sleep and nesting behavior in primates: A review
Authors: Fruth Barbara , Tagg Nikki , Stewart Fiona 
Published: July 2018

AbstractSleep is a universal behavior in vertebrate and invertebrate animals, suggesting it originated in the very first life forms. Given the vital function of sleep, sleeping patterns and sleep architecture follow dynamic and adaptive processes reflecting trade‐offs to different selective pressures.Here, we review responses in sleep and sleep‐related behavior to environmental constraints across primate species, focusing on the role of great ape nest building in hominid evolution. We summarize and synthesize major hypotheses explaining the proximate and ultimate functions of great ape nest building across all species and subspecies; we draw on 46 original studies published between 2000 and 2017. In addition, we integrate the most recent data brought together by researchers from a complementary range of disciplines in the frame of the symposium “Burning the midnight oil” held at the 26th Congress of the International Primatological Society, Chicago, August 2016, as well as some additional contributors, each of which is included as a “stand‐alone” article in this “Primate Sleep” symposium set. In doing so, we present crucial factors to be considered in describing scenarios of human sleep evolution: (a) the implications of nest construction for sleep quality and cognition; (b) the tree‐to‐ground transition in early hominids; (c) the peculiarities of human sleep.We propose bridging disciplines such as neurobiology, endocrinology, medicine, and evolutionary ecology, so that future research may disentangle the major functions of sleep in human and nonhuman primates, namely its role in energy allocation, health, and cognition.

AbstractBiosynthetic considerations inspired us to harness the templating properties offered by DNA to promote a [2+2] photoinduced cycloaddition. The method was developed based on the dimerization of (E)‐aplysinopsin, which was previously shown to be unproductive in solution. In sharp contrast, exposure of this tryptophan‐derived olefin to light in the presence of salmon testes DNA (st‐DNA) reproducibly afforded the corresponding homo‐dimerized spiro‐fused cyclobutane in excellent yields. DNA provides unique templating interactions enabling a singular mimic of the solid‐state aggregation necessary for the [2+2] photocycloaddition to occur. This method was ultimately used to promote the prerequisite dimerizations leading to both dictazole B and tubastrindole B, thus constituting the first example of a DNA‐mediated transformation to be applied to the total synthesis of a natural product.
Post‐Synthetic Ligand Exchange in Zirconium‐Based Metal–Organic Frameworks: Beware of The Defects!

Published: July 2018

AbstractPost‐synthetic ligand exchange in the prototypical zirconium‐based metal–organic framework (MOF) UiO‐66 was investigated by in situ solution 1H NMR spectroscopy. Samples of UiO‐66 having different degrees of defectivity were exchanged using solutions of several terephthalic acid analogues in a range of conditions. Linker exchange only occurred in defect‐free UiO‐66, whereas monocarboxylates grafted at defect sites were found to be preferentially exchanged with respect to terephthalic acid over the whole range of conditions investigated. A 1:1 exchange ratio between the terephthalic acid analogue and modulator was observed, providing evidence that the defects had missing‐cluster nature. Ex situ characterisation of the MOF powders after exchange corroborated these findings and showed that the physical‐chemical properties of the MOF depend on whether the functionalisation occurs at defective sites or on the framework.
Tourism in Pacific island countries: A status quo round‐up

Published: July 2018

AbstractIn the 21st century, Pacific island countries (PICs) continue to leverage for tourism the attributes that have imbued them, including appeals to their cultural, geographical, and climatic allure. However, the question raised more frequently by many is why despite the many decades of tourism across the region, development impacts from the sector remain largely muted. The key remit of this paper is to offer a status quo round‐up of tourism in PICs and to draw on key emergent themes that underlay the present context. There is little doubt that for policymakers and their international development partners, whether tourism has or can lead to enduring development outcomes remains clouded in questions over whether there is ample evidence available to support such assertions. However, this has failed to dampen the enthusiasm of multilateral agencies that promote the notion that tourism's potential remains largely underdeveloped. With largely narrow economic bases, PICs have little choice but to seek further development of tourism despite the many fundamental constraints that make them less competitive than Southeast Asian destinations.
Filter‐based isolation, enrichment, and characterization of circulating tumor cells

Published: July 2018

AbstractIsolation of circulating tumor cells (CTCs) from blood has long been a challenge due to the rarity and heterogeneity of these cells. Detection technologies have predominantly focused on different molecular or physical properties of CTCs. Size‐based isolation approach using microfilters have been widely used to capture CTCs because of the difference in size and stiffness of the cells compared to other hemocytes. Isolation of rare cells based on their size was the original CTC enrichment technique and it demonstrated a simple yet rapid method that enhanced the recovery of cells with high throughput. In this review, we highlight key technical aspects of filter‐based isolation, detection, and characterization of CTCs, and compare the clinical performance of filter‐based devices with the approved platforms and immunoassays used for the analysis of CTCs. We have also discussed future prospective and incorporation of advances in immunochemistry technique into the filter‐based platforms for enhancing the utility in clinical settings.

AbstractThis study aimed at evaluating the diagnostic and prognostic role of neopterin (Npt) concentration in the cerebrospinal fluid (CSF) of patients with primary central nervous system lymphoma (PCNSL). Ninety‐nine patients were enrolled in this retrospective study; these included patients with PCNSL (n = 21), other brain tumors (n = 44), and inflammatory diseases (n = 34). CSF Npt concentration was measured using ELISA. Receiver operating characteristic (ROC) curve analysis was performed to assess the discriminative ability of CSF Npt concentration for the diagnosis of PCNSL. CSF Npt concentration in patients with PCNSL was significantly higher than that in patients with other brain tumors and inflammatory diseases (P < .001). On ROC curve analysis, the optimal cutoff CSF Npt level of 10.77 ng/mL for the diagnosis of PCNSL and the diagnostic yield of MRI were increased when used in conjunction with CSF Npt concentration. The CSF Npt concentrations in PCNSL patients with multiple lesions were significantly higher than those in patients with a single lesion. Changes in CSF Npt concentration were consistent with post‐treatment changes in tumor sizes. The CSF Npt concentration may be a good biomarker for the diagnosis, for monitoring of disease course, and for prognostic evaluation of patients with PCNSL.
