Authors: Rumyantseva Marina , Makeeva Ekaterina , Gaskov Alexander , Shepel Nikolay , Peregudova Svetlana , Khoroshutin Andrey , Tokarev Sergey , Fedorova Olga
Published: November 2017

This paper deals with the functionalization of nanocrystalline SnO2 with Cu(II) complexes with organic ligands, aimed at the improvement of sensor selectivity towards gas molecules. For the synthesis of metalorganic/SnO2 hybrid material complexes of Cu(II) with phthalocyanine, porphyrinines, bipyridine and azadithiacrown etherwere used. The analysis of gas sensor properties showed the possibility of increasing the sensitivity and selectivity of hybrid materials in H2S detection due to the electron transfer from SnO2 to an adsorbed organic molecule, which changes during the interaction between H2S and Cu(II) ions.

Published: November 2017

The insertion of rigid monomers such as isosorbide into poly(ethylene terephthalate) (PET) allows for the access of polymers with improved properties, notably in terms of thermal stability. This biobased monomer is however poorly reactive, and harsh reaction conditions lead to color concerns regarding the resulting polymer. This has motivated the development of catalytic systems enabling an increase of the reaction rate and a good coloration. In this study, we have assessed bimetallic catalytic systems based on the main metals used for PET catalysis, i.e., antimony, germanium and titanium, for the synthesis of poly(ethylene terephthalate-co-isosorbide terephthalate) (PEIT). The Sb2O3/Ti(OiPr)4 combination leads to a high reaction rate while maintaining an acceptable coloration. On the other hand, combining Sb2O3 with GeO2 affords the formation of poly(ethylene terephthalate-co-isosorbide terephthalate) without coloration concerns and a reaction rate higher than that observed using the single metal catalysts. Molecular weights and microstructure including diethyleneglycol (DEG) and isosorbide contents are also discussed, together with the thermal properties of the resulting PEIT. The GeO2/Ti(OiPr)4 is also assessed, and leads to average performances.

Published: November 2017

Maleic anhydride (MAH) was used as the grafting monomer, which was prepared by melt grafting reaction in the twin screw extruder with dicumyl peroxide (DCP) as the initiator, polylactic acid grafted with maleic anhydride (MAH-g-PLA) was successfully prepared as the interface compatibilizer. The PLA/Wood fiber/MAH-g-PLA composites were prepared by melt blending and injection molding with different proportions of compatibilizer added, within which PLA was for the matrix phase and wood fiber was for the reinforcing phase. The crystallinity, microstructure, thermal stability and dynamic thermomechanical property of the composites were studied by X-ray diffraction (XRD), scanning electron microscope (SEM), thermo gravimetric analyzer (TGA) and dynamic mechanical thermal analysis (DMA). Furthermore, the mechanical and water absorption properties of the composites were also characterized. Results showed that the tensile strength and flexural strength of the composites attained the highest at 30% MAH-g-PLA added, where the crystallinity of the composites also showed the highest value. DMA results showed that the addition of MAH-g-PLA interfacial compatibilizer increased the loss modulus of the composites and improved the toughness. Scanning electron microscopy (SEM) showed that when the MAH-g-PLA was used, wood fiber is well dispersed in the PLA matrix phase, and that the interfacial compatibility between the matrix and the enhanced phase was improved. Therefore, the addition of MAH-g-PLA could improve the interfacial compatibility of PLA/Wood fiber composites and improve the mechanical properties of the composites.
Protection of Religious Signs under Trademark Law: A Perspective of China’s Practice
Authors: Liu Wenqi
Published: November 2017

This article looks at how religious signs are increasingly used in trade and how misappropriation can be harmful to the identity and preservation of religious cultures. Research has shown that trademark rules can be used to help prevent such issues occurring in trade. Some religious entities have also taken trademark strategies to safeguard their religious signs. Considering that religious signs are generally regarded as common patrimony, a balanced system is more beneficial to both the public and trademark proprietors. This research delves into the theory that the trademark system should ensure that the non-commercial use of religious signs used for historical, cultural and social purposes, remains in the public domain. By analyzing China’s practice of protecting religious signs, this article finds that despite the success of certain religious entities in safeguarding religious trademarks, their approach is not necessarily feasible for wide application. The article suggests that the government should do more to protect religious signs by using trademark rules under which any signs detrimental to religious identity, value or culture should be refused for registration and prohibited from use. Also, in certain cases, social organizations and individuals should be entitled and encouraged to participate in the protection of religious signs.

Published: November 2017

Diameter at breast height (DBH) is one of the most important parameter in forestry. With increasing use of terrestrial and airborne laser scanning in forestry, new exceeding possibilities to directly derive DBH emerge. In particular, high resolution point clouds from laser scanners on board unmanned aerial systems (UAS) are becoming available over forest areas. In this case study, DBH estimation from a UAS point cloud based on modeling the relevant part of the tree stem with a cylinder, is analyzed with respect to accuracy and completeness. As reference, manually measured DBHs and DBHs from terrestrial laser scanning point clouds are used for comparison. We demonstrate that accuracy and completeness of the cylinder fit are depending on the stem diameter. Stems with DBH > 20 cm feature almost 100% successful reconstruction with relative differences to the reference DBH of 9% (DBH 20–30 cm) down to 1.8% for DBH > 40 cm.

Authors: Lee Da Eun , Lee Young Jin , Shin Eunso , Kwon Soon-Hong
Published: November 2017

A Mach-Zehnder interferometer based on a plasmonic channel waveguide is proposed for refractive index sensing. The structure, with a small physical footprint of 20 × 120 μm2, achieved a high figure of merit of 294. The cut-off frequency behaviour in the plasmonic channel waveguide resulted in a flat dispersion curve, which induces a 1.8 times larger change of the propagation constant for the given refractive index change compared with previously reported results.
Sending a Dear John Letter: Public Information Campaigns and the Movement to “End Demand” for Prostitution in Atlanta, GA
Authors: Majic Samantha
Published: November 2017

This paper examines “Dear John”, a public information campaign that ran from 2006–2008 in Atlanta, GA, to ask what narrative it conveys about commercial sex and those who engage in it, in order to understand the gendered (and other) discursive constructions it produces, reflects, and complicates about these activities and subjects. Drawing from both policy and sex work/trafficking scholarship, this paper argues that Dear John used symbolic images and direct and consequential text to convey a “male demand” narrative, which holds that men’s demand for sexual services harms girls and young women and will not be tolerated. Yet, in so doing, Dear John also reinforced particularly gendered characterizations of individuals who trade sex, while de-emphasizing other factors that increase young peoples’ vulnerabilities to and within sex work. The paper concludes by discussing Dear John’s outcomes and significance for scholars concerned with sex work, policy, and social change.
A Joint Optimal Decision on Shipment Size and Carbon Reduction under Direct Shipment and Peddling Distribution Strategies
Authors: Min Daiki , Chung Kwanghun
Published: November 2017

Recently, much research has focused on lowering carbon emissions in logistics. This paper attempts to contribute to the literature on the joint shipment size and carbon reduction decisions by developing novel models for distribution systems under direct shipment and peddling distribution strategies. Unlike the literature that has simply investigated the effects of carbon costs on operational decisions, we address how to reduce carbon emissions and logistics costs by adjusting shipment size and making an optimal decision on carbon reduction investment. An optimal decision is made by analyzing the distribution cost including not only logistics and carbon trading costs but also the cost for adjusting carbon emission factors. No research has explicitly considered the two sources of carbon emissions, but we develop a model covering the difference in managing carbon emissions from transportation and storage. Structural analysis guides how to determine an optimal shipment size and emission factors in a closed form. Moreover, we analytically prove the possibility of reducing the distribution cost and carbon emissions at the same time. Numerical analysis follows validation of the results and demonstrates some interesting findings on carbon and distribution cost reduction.
A Market Equilibrium Supply Chain Model for Supporting Self-Manufacturing or Outsourcing Decisions in Prefabricated Construction
Authors: Han Yanhu , Skibniewski Miroslaw , Wang Lufan
Published: November 2017

Prefabricated construction is a sustainable alternative to traditional on-site construction methods. However, many challenges still exist in the prefabricated construction process. For example, self-manufacturing or outsourcing decisions are vital to the industrial structure and organization of the prefabricated construction industry, and the company’s production and operation decision-making. This paper considers a prefabricated construction supply chain, which is composed of one upstream component manufacturing company and two downstream contractors. The large contractor can get the precast component through self-manufacturing or outsourcing, while the small and medium-sized enterprise (SME) contractor can only buy components from the component manufacturer. A comprehensive game model (Cournot-Stackelberg model) under different decisions, that is, component self-manufacturing or outsourcing, was established. By solving the profit functions of different companies in the prefabricated construction supply chain, the equilibrium solutions of output, price and profit can be achieved. These solutions of equilibrium indicate the optimal decision on the production and operation, and the profit’s boundary conditions. After assuming relevant parameters, the profit levels of the companies in the supply chain are analyzed via a dynamic simulation in the changing process of prefabricated construction market size under different behavioral decisions. The conclusions are as follows: (1) the profit levels of all supply chain enterprises and the whole supply chain are increasing with an increase of market size; (2) the downstream contractors and the whole supply chain have a higher profit level under the component self-manufacturing decision, however, on the contrary, the upstream component suppliers get a higher profit level under the component outsourcing decision; (3) the equilibrium output of the SME contractor is reduced under the outsourcing decision of the large contractor, and the SME contractor is at a disadvantage in market competition, which is particularlyfull of risk when the market size is not big enough, but higher profit level can be expected as the market size increases. According to the results of the game-theoreticanalysis and the numerical simulation, managerial implications are put forward from the angles of extensive publicity, mandatory implementation, strengthening industrial chain integration, and intensifying component factory guidance to promote the development of prefabricated construction. Finally, the main problems which need to be studied further in the future are presented.
Assessing Urban Sustainability Using a Multi-Scale, Theme-Based Indicator Framework: A Case Study of the Yangtze River Delta Region, China
Authors: Li Cheng , Li Junxiang
Published: November 2017

Urban sustainability is a great concern worldwide. However, how to evaluate urban sustainability is still a big challenge because sustainable development is multifaceted and scale dependent, which demands various assessment methods and indicators that often do not reach a consensus. In this study, we assessed urban sustainability of the Yangtze River Delta (YRD), China during 2000–2014 at two spatial scales (corresponding to the administrative levels of province and prefecture). A theme-based indicator framework, cluster analysis and Mann–Kendall test were used for urban sustainability assessment. Our results showed that the overall (OS), social (SS), and economic sustainability (EcS) scores for two provinces and sixteen prefectural cities increased from 2000 to 2014 in general, but the environmental sustainability (EnS) scores decreased over time. According to the performance of SS, EnS and EcS at the prefectural level, three distinct city clusters were identified: Cluster 1 with high SS and EcS but low EnS; Cluster 2 with low SS and EcS but high EnS; and Cluster 3 with moderate SS, EnS and EcS. The three sustainability dimensions—society, environment and economy—all changed over time and differed among cities at the two administrative levels. Our results implied that, according to the “strong sustainability” perspective, the cities of the YRD became less sustainable or unsustainable because the social and economic progresses were at the expense of the environment. The level of urban sustainability was lower at the provincial level than the prefectural level, implying that the problems of unsustainability are even greater at the provincial level than the prefectural level in the YRD region.
Multi-Attribute Decision-Making Based on Prioritized Aggregation Operator under Hesitant Intuitionistic Fuzzy Linguistic Environment
Authors: Liu Peide , Mahmood Tahir , Khan Qaisar
Published: November 2017

A hesitant intuitionistic fuzzy linguistic set (HIFLS) that integrates both qualitative and quantitative evaluations is an extension of the linguistic set, intuitionistic fuzzy set (IFS), hesitant fuzzy set (HFS) and hesitant intuitionistic fuzzy set (HIFS). It can describe the qualitative evaluation information given by the decision-makers (DMs) and reflect their uncertainty. In this article, we defined some new operational laws and comparative method for HIFLSs. Then, based on these operations, we propose two prioritized aggregation (PA) operators for HIFLSs: prioritized weighted averaging operator for HIFLSs (HIFLPWA) and prioritized weighted geometric operator for HIFLSs (HIFLPWG). Based on these aggregation operators, an approach for multi-attribute decision-making (MADM) is developed under the environment of HIFLSs. Finally, a practical example is given to show the practicality and effectiveness of the developed approach by comparing with the other representative methods.
Begomoviral Movement Protein Effects in Human and Plant Cells: Towards New Potential Interaction Partners

Published: November 2017

Geminiviral single-stranded circular DNA genomes replicate in nuclei so that the progeny DNA has to cross both the nuclear envelope and the plasmodesmata for systemic spread within plant tissues. For intra- and intercellular transport, two proteins are required: a nuclear shuttle protein (NSP) and a movement protein (MP). New characteristics of ectopically produced Abutilon mosaic virus (AbMV) MP (MPAbMV), either authentically expressed or fused to a yellow fluorescent protein or epitope tags, respectively, were determined by localization studies in mammalian cell lines in comparison to plant cells. Wild-type MPAbMV and the distinct MPAbMV: reporter protein fusions appeared as curled threads throughout mammalian cells. Co-staining with cytoskeleton markers for actin, intermediate filaments, or microtubules identified these threads as re-organized microtubules. These were, however, not stabilized by the viral MP, as demonstrated by nocodazole treatment. The MP of a related bipartite New World begomovirus, Cleome leaf crumple virus (ClLCrV), resulted in the same intensified microtubule bundling, whereas that of a nanovirus did not. The C-terminal section of MPAbMV, i.e., the protein’s oligomerization domain, was dispensable for the effect. However, MP expression in plant cells did not affect the microtubules network. Since plant epidermal cells are quiescent whilst mammalian cells are proliferating, the replication-associated protein RepAbMV protein was then co-expressed with MPAbMV to induce cell progression into S-phase, thereby inducing distinct microtubule bundling without MP recruitment to the newly formed threads. Co-immunoprecipitation of MPAbMV in the presence of RepAbMV, followed by mass spectrometry identified potential novel MPAbMV-host interaction partners: the peptidyl-prolyl cis-trans isomerase NIMA-interacting 4 (Pin4) and stomatal cytokinesis defective 2 (SCD2) proteins. Possible roles of these putative interaction partners in the begomoviral life cycle and cytoskeletal association modes are discussed.
Crystal Structure of the Full-Length Feline Immunodeficiency Virus Capsid Protein Shows an N-Terminal β-Hairpin in the Absence of N-Terminal Proline
Authors: Folio Christelle , Sierra Natalia , Dujardin Marie , Alvarez Guzman , Guillon Christophe
Published: November 2017

Feline immunodeficiency virus (FIV) is a member of the Retroviridae family. It is the causative agent of an acquired immunodeficiency syndrome (AIDS) in cats and wild felines. Its capsid protein (CA) drives the assembly of the viral particle, which is a critical step in the viral replication cycle. Here, the first atomic structure of full-length FIV CA to 1.67 Å resolution is determined. The crystallized protein exhibits an original tetrameric assembly, composed of dimers which are stabilized by an intermolecular disulfide bridge induced by the crystallogenesis conditions. The FIV CA displays a standard α-helical CA topology with two domains, separated by a linker shorter than other retroviral CAs. The β-hairpin motif at its amino terminal end, which interacts with nucleotides in HIV-1, is unusually long in FIV CA. Interestingly, this functional β-motif is formed in this construct in the absence of the conserved N-terminal proline. The FIV CA exhibits a cis Arg–Pro bond in the CypA-binding loop, which is absent in known structures of lentiviral CAs. This structure represents the first tri-dimensional structure of a functional, full-length FIV CA.
An Integrated Approach Based on Numerical Modelling and Geophysical Survey to Map Groundwater Salinity in Fractured Coastal Aquifers
Authors: Masciopinto Costantino , Liso Isabella , Caputo Maria , De Carlo Lorenzo
Published: November 2017

Aquifer over-exploitation may increase coastal seawater intrusion by reducing freshwater availability. Fractured subsurface formations commonly host important freshwater reservoirs along sea coasts. These water resources are particularly vulnerable to the contamination due to seawater infiltration occurring through rapid pathways via fractures. Modeling of density driven fluid flow in fractured aquifers is complex, as their hydrodynamics are controlled by interactions between preferential flow pathways, 3D interconnected fractures and rock-matrix porosity distribution. Moreover, physical heterogeneities produce highly localized water infiltrations that make the modeling of saltwater transport in such aquifers very challenging. The new approach described in this work provides a reliable hydrogeological model suitable to reproduce local advancements of the freshwater/saltwater wedge in coastal aquifers. The proposed model use flow simulation results to estimate water salinities in groundwater at a specific depth (1 m) below water table by means of positions of the Ghyben-Herzberg saltwater/freshwater sharp interface along the coast. Measurements of salinity in 25 boreholes (i.e., salinity profiles) have been used for the model calibration. The results provide the groundwater salinity map in freshwater/saltwater transition coastal zones of the Bari (Southern Italy) fractured aquifer. Non-invasive geophysical measurements in groundwater, particularly into vertical 2D vertical cross-sections, were carried out by using the electrical resistivity tomography (ERT) in order to validate the model results. The presented integrated approach is very easy to apply and gives very realistic salinity maps in heterogeneous aquifers, without simulating density driven water flow in fractures.
Speaking of "Travel" in English and Russian: Lexical Semantics in Tourist Reviews
Authors: Permyakova Tatiana M. , Morozova Irina S. , Smolianina Elena A.
Published: November 2017

The purpose of this study is to analyze the linguistic universality and variability of the concept oftravelin the English and Russian languages. The linguistic method employs a four-step procedure including analysis of culturally "biased" dictionary entries of travel vocabulary in English and in Russian as well as a comparative analysis of lexical structures in English and Russian discursive contexts. The data include: (a) 14 concise dictionaries containing 14 definitions of the wordtraveland 42 definitions of its synonyms, and (b) 774 user-generated collocations and word combinations withtravel, collected from on-line tourists' reviews on English and Russian travel websites. The results show that, despite common background information on Destination, Time, and Means of Transport, there are selective ways in which English-speaking and Russian-speaking tourists perceive their travel experiences. In particular, even in the context of global traveling and the use of similar words, English-speaking and Russian-speaking tourists see some of the themes (Memorable travel, Fabulous travel, Nature, Feelings, and Emotions) differently. From an interlinguistic perspective, the results of the study are indicative of stereotypical linguistic reactions to travel experiences in the English language, and of an emphasis on the differentiation of feelings in the Russian language as a manifestation of tourists' linguistic personality and cultural identity.
Resolving the northern hemisphere source region for the long‐distance dispersal event that gave rise to the South American endemic dung moss Tetraplodon fuegianus
Authors: Lewis Lily R. , Biersma Elisabeth M. , Carey Sarah B. , Holsinger Kent , McDaniel Stuart F. , Rozzi Ricardo , Goffinet Bernard
Published: November 2017

PREMISE OF THE STUDY:

American bipolar plant distributions characterize taxa at various taxonomic ranks but are most common in the bryophytes at infraspecific and infrageneric levels. A previous study on the bipolar disjunction in the dung moss genus Tetraplodon found that direct long‐distance dispersal from North to South in the Miocene–Pleistocene accounted for the origin of the Southern American endemic Tetraplodon fuegianus, congruent with other molecular studies on bipolar bryophytes. The previous study, however, remained inconclusive regarding a specific northern hemisphere source region for the transequatorial dispersal event that gave rise to T. fuegianus.

METHODS:

To estimate spatial genetic structure and phylogeographic relationships within the bipolar lineage of Tetraplodon, which includes T. fuegianus, we analyzed thousands of restriction‐site‐associated DNA (RADseq) loci and single nucleotide polymorphisms using Bayesian individual assignment and maximum likelihood and coalescent model based phylogenetic approaches.

KEY RESULTS:

Northwestern North America is the most likely source of the recent ancestor to T. fuegianus.

CONCLUSIONS:

Tetraplodon fuegianus, which marks the southernmost populations in the bipolar lineage of Tetraplodon, arose following a single long‐distance dispersal event involving a T. mnioides lineage that is now rare in the northern hemisphere and potentially restricted to the Pacific Northwest of North America. Furthermore, gene flow between sympatric lineages of Tetraplodon mnioides in the northern hemisphere is limited, possibly due to high rates of selfing or reproductive isolation.
Chandra Imaging of the Outer Accretion Flow onto the Black Hole at the Center of the Perseus Cluster
Authors: Miller J. M. , Bautz M. W. , McNamara B. R.
Published: November 2017

Nowhere is black hole feedback seen in sharper relief than in the Perseus cluster of galaxies. Owing to a combination of astrophysical and instrumental challenges, however, it can be difficult to study the black hole accretion that powers feedback into clusters of galaxies. Recent observations with Hitomi have resolved the narrow Fe Kα line associated with accretion onto the black hole in NGC 1275 (3C 84), the active galaxy at the center of Perseus. The width of that line indicates that the fluorescing material is located 6–45 pc from the black hole. Here, we report on a specialized Chandra imaging observation of NGC 1275 that offers a complementary angle. Using a sub-array, sub-pixel event repositioning, and an X-ray “lucky imaging” technique, Chandra imaging suggests an upper limit of about 0.3 arcsec on the size of the Fe Kα emission region, corresponding to ∼98 pc. Both spectroscopy and direct imaging now point to an emission region consistent with an extended molecular torus or disk, potentially available to fuel the black hole. A low X-ray continuum flux was likely measured from NGC 1275; contemporaneously, radio flaring and record-high GeV fluxes were recorded. This may be an example of the correlation between X-ray flux dips and jet activity that is observed in other classes of accreting black holes across the mass scale.

En attendant l’affect. Une lecture de l’ennui dans l’ œ uvre de Jean Echenoz
Authors: Morel Alexandre
Published: November 2017

Pour en éclairer la saisie, l’auteur aborde les figures de l’ennui dans l’œuvre romanesque de Jean Echenoz. L’ennui est envisagé comme régulateur économique qui, dans le même temps, tient à distance les personnages les uns des autres mais permet aussi d’ouvrir l’attention à des formes nouvelles. Dans la genèse de ces formes s’éclairent mutuellement l’attention poétique du descripteur et les particularités de l’écoute analytique. Un tournant dans la seconde moitié de l’œuvre permet aux lecteurs comme aux personnages de renouer avec les affects tenus à distance par l’ennui comme avec les identifications empêchées jusqu’alors par la distanciation, l’ennui étant envisagée comme expérience de désincarnation.

Dans le contexte socio-culturel argentin, propice à recevoir les idées avant-gardistes du monde, l’auteur estime que la psychanalyse a connu un vigoureux développement. Il considère aussi qu’on peut y reconnaître un axe théorique en accord avec ses recherches et son expérience clinique. Ce courant, qu’il a caractérisé comme le versant psychosocia l de la psychanalyse, part de l’empreinte originale qu’a laissée la pensée de Enrique Pichon Rivière et de ses disciples les plus créatifs, José Bleger, David Liberman et Madeleine et Willy Baranger. De leurs idées part une grande partie de ses propres contributions, sans minimiser pour autant l’influence qu’ont exercée sur lui d’autres auteurs, argentins ou non.
La saturation de la conscience dans les rêves, les séances, les sciences
Authors: Chervet Bernard
Published: November 2017

Les processus de pensée ont la capacité de réaliser, comme dans le rêve et les séances, une saturation de la conscience réduisant la perception à la réalité qu’ils produisent. Cette saturation a fonction de limiter les éprouvés de manque. Ce mécanisme est impliqué dans la recherche scientifique. Il produit l’effet de vérité. Toute découverte est porteuse d’un « perceptif » créé par et nécessaire au fonctionnement mental du chercheur. Mais jamais la recherche de l’équation de la vérité, n’abolira notre condition d’impuissance.
Une troisième méthode ?
Authors: Denis Anne
Published: November 2017

Les derniers textes de Freud comportent une série de réflexions inhabituelles, et peu reprises par la suite, qui, rassemblées ici, donnent à penser à un troisième temps méthodologique, après ceux de 1912 et de 1922. La référence répétitive au moi comme visée de la cure s’efface devant une préoccupation d’appréhension du ça et de la vérité historique ; et va jusqu’à l’évocation d’un savoir mystique, dans les dernières notes. L’analogie entre ce savoir et le processus créateur indiquerait que la dernière méthode freudienne aborde un contre-transfert dans lequel la régression de la pensée hors langage aboutit au « délire » de la construction. Les traces amnésiques, appréhendées par un contre-transfert homologue, sont alors organisées en représentations.
L’émotion et la technique dans une dimension performative
Authors: Ronca Miriam
Published: November 2017

Que se passe-t-il lorsqu’on regarde une image ? Quelle serait la connexion entre les images et les « symptômes » et les réactions, émotionnelles, biologiques et comportementales des spectateurs ? Ces questions, posées par David Freedberg, historien de l’art à la Columbia University de New York, montrent avec évidence que la réponse du spectateur, ainsi que la relation étroite entre les neurosciences et les représentations du corps, ne sont pas encore complètement problématisées. La phénoménologie des réactions des spectateurs est analysée ici non pas pour une enquête sur l’histoire des réceptions de l’observateur et sa relation à l’image, mais plutôt comme témoignage de cette émotivité qui dépend directement de l’image même. À ces fins, notre analyse se focalise sur le site web Anatomicaltravelogue.com d’Alexander Tsiaras, artiste et physician à la Yale University, qui présente un nombre considérable de représentations corporelles – fabriquées numériquement et représentées par une construction visuelle – liées à des réponses émotionnelles. L’objectif est de mieux définir le régime émotionnel en tant qu’indicateur des diverses relations entre image et spectateur, ainsi que de comprendre comment les expériences émotionnelles participent à la construction d’un système de sens spécifique exprimé à travers le corps.

A Novel Method of Patient Positioning Using Shoulder Arthroscopy Equipment for Elbow Arthroscopy
Authors: Kowalski Julianne M. , Monica James T.
Published: November 2017

Indications for elbow arthroscopy are expanding; however, it is uncommon compared with shoulder arthroscopy. Elbow arthroscopy can be complicated by positioning, including the need to obtain specific arm holders required by most operating rooms. Surgery can be performed in the supine, prone, or lateral position. Arm traction allows for distraction of the joint space, full insufflation, and therefore visualization of intra-articular anatomy. This article outlines a new technique using previously available shoulder arthroscopy equipment to avoid increased cost incurred by procuring new, elbow-specific equipment. This technique is performed in the supine position using a hydraulic system and a shoulder 3-point distractor. [

Valved 25-Gauge Cannula for Vitreous Tap and Injection
Authors: Leng Theodore , Moshfeghi Darius M.
Published: November 2017

BACKGROUND AND OBJECTIVES:

To describe a technique that reduces patient discomfort by using a valved 25-gauge trocar for vitreous tap and intravitreal injection of medications in previously vitrectomized eyes with suspected infectious endophthalmitis.

PATIENTS AND METHODS:

A commercially available 25-gauge valved entry system is used to enter the vitreous cavity. A 25-gauge needle attached to a syringe is used to obtain a vitreous specimen for microbiological access and administer intravitreal injections of antibiotics and steroids. No vitreous volume is lost during these procedures because of the cannula's valve. At the completion of the tap and injections, the cannula is removed with forceps and the single wound tamponaded with a cotton-tipped applicator.

RESULTS:

With this method, a vitreous tap and injection of pharmacologic agents only requires one piercing through the sclera, instead of the usual four piercings.

CONCLUSION:

With this new technique, it is possible to enhance patient comfort, decreased pain, and reduce trauma to the conjunctiva.

Published: November 2017

Torpedo maculopathy is a rare congenital anomaly of the retinal pigment epithelium (RPE). Various imaging modalities have been used to assess cases of torpedo maculopathy, including optical coherence tomography (OCT) and fundus autofluorescence (FAF). OCT angiography (OCTA) offers combined structural and flow characteristics of imaged lesions. The authors present OCTA findings in two cases of torpedo maculopathy. Common features include loss of RPE and choriocapillaris allowing greater visualization of larger vessels in the outer choroid. This confirms the potential of OCTA to provide greater detail of retinal and choroidal architecture and elucidate the histopathology of retino-choridal lesions.

Published: November 2017

Blood transfusion is a commonly-performed medical procedure that improves and saves the lives of patients. However, this procedure also has significant risks, is sometimes used inappropriately and has substantial costs associated with the collection, testing, processing and distribution of blood and blood products.

BloodSafe eLearning Australia (BEA) (www.bloodsafelearning.org.au) is an education program for Australian doctors, nurses and midwives, designed to improve the safety and quality of clinical transfusion practice. Courses are interactive and include case studies, videos, and best-practice tips. Successful completion of a multiple-choice assessment provides learners with a certificate of completion. To date there are more than 400,000 registered learners, from more than 1500 organisations, who have completed more than 765,000 courses.

Stakeholder feedback shows that the program: provides credible, consistent education across Australia; is cost effective; reduces duplication; is ‘best-practice’ elearning that is readily accessible; allows institutions to focus on practical aspects of transfusion education; results in change to clinical practice; and supports the broader implementation of a blood management strategy in Australia.

User evaluation shows that the courses have a positive impact, with 89% of respondents stating they had gained additional knowledge of transfusion practice, processes and/or policy and more than 87% reporting they will make, or have made, changes to their work practices which will improve patient safety and outcomes.
The BloodSafe eLearning Australia program provides education to a large number of health professionals across Australia. Evaluation demonstrates that these courses provide users with a consistent and reliable knowledge base that translates into changes to practice and improved patient outcomes.

Published: November 2017

Mobile computing and wireless technologies are transforming traditional educational patterns. The use of mobile devices for educational purposes led to what is known as mobile learning. In recent years, mobile learning strategies have been increasingly adopted in higher education. They support personalized, informal, situated, contextualized and ubiquitous learning. In practice, we have witnessed that courses in software engineering education often do not lead to the expected learning outcomes. In this paper, we will therefore present a motivating and learner-centered approach for mobile e-learning in application prototyping. We use mobile devices as key enabler serving different didactic functions in the context of learning, prototyping and collaboration.
Studies of E-Learning in Practice
Authors: Rechberger Manfred
Published: November 2017

Computer assisted and computer based applications become more and more important in everyday lives. Their implementation in the field of music education seems to become a long-term project. Whereas years ago we were sure about the fact, that the quality of e-learning at our University of Music and Performing Arts depends on the implementation of audio-visual media at our e-learning platform, nowadays the text based tasks and written journals have won the race at least in the statistic of usage. 

Many modules containing multimedia based content promote creative processes and different learning situations. Advantages of e-learning include flexibility and convenience for learners, especially if they have more variety in learning experiences by using multimedia applications. This paper deals with the change of our user behaviors in the last years, discussion forums, blogs, wikis and collaborative online activities and focuses on tools for musicians, composers and music scientists based on the actual status of the discussions in media pedagogies. A scientific project including surveys about the advantages and disadvantages of digital teaching repositories describes common used online music tools.

Creative tourism has been a proficuous ground for the implementation of ICT's (Information and Communications Technology) strategies and the so-called creative industries. New cultural mediators are changing tourism consumption. Postmodern consumers have brought new perceptions to cocreation processes through user-generated content, eWOM (Electronic Word of Mouth), peer-to-peer exchange, collaborative economy, SoLoMo (social-local-mobile) tourists, among others. Booktubers and music fans/consumers in Chile constitute examples of diverse consumption through virtual and physical mediation, as capital construction enables social practices. In this exploratory study, the authors discuss how creative experiences are being consumed through cultural mediation made possible by technological developments. The creative tourism network website is analysed in the light of postmodern cultural mediation and capital construction.

Authors: Schuh Till Maximilian , Agapito Dora , Pinto Patrícia
Published: November 2017

This study aims at measuring the image of the tourism brand “España Verde” by using the social media platform Facebook. The ever-increasing competition within the tourism industry makes it vital for destinations to address their target group by tailored marketing measures. Furthermore social media channels are changing the interaction between Destination Management Organizations (DMOs) and customers. With the aim of exploring España Verde's image, a three components approach—cognitive, affective and conative was applied. Related to the measurement of the cognitive component, the study also focuses on España Verde's touristic potential ranging from a rich and diverse culture as well as a unique natural heritage to a suitable infrastructure for touristic purposes. Although the supply side seems to fit the target group's desires when choosing a vacation destination, the exploratory results reveal that there is currently only little awareness for España Verde on the German market.

This chapter discusses the relationship between engagement actions during the experiences in game advertising, with the aim to investigate the elements that support consumer action in a Virtual Reality (VR) game developed for Oculus Rift. Since VR can be understood as a potential investment in advertising platform, the proposal of this chapter is to comprehend the experience of engagement with brands inside the game, including aspects about VR gameplay and immersion. For that, the researchers developed a game with different levels of brand integration in a VR environment. In order to measure engagement levels in this experience, the researchers have invited 24 participants to play the game to observe their behaviors. As a result of this study, it is suggested that the VR can be a useful environment to insert advertising for multi-platforms experiences, since it can promote an emotional and cognitive experiences around the brand and not only a simple exposition of the advertising.
