Environmental Innovation and Employment: Drivers and Synergies
Authors: Triguero Ángela , Cuerva María , Álvarez-Aledo Carlos
Published: November 2017

Numerous empirical studies focus on the drivers of environmental innovation or their potential employment effects. Nevertheless, we have scarce knowledge about whether factors that influence eco-innovation and employment generation are related. The main purpose is to analyze the synergies between eco-innovation and employment using a sample of more than 6000 innovative Spanish manufacturing and service firms. Using different econometric procedures, the main findings show that size, R&D and export influence eco-innovation and employment in the same direction, while age, belonging to a group, public subsidies and internal and external knowledge sources exert a different effect. Thus, older firms create less employment but have a high probability of being environmental innovators compared with younger firms. Furthermore, the size of the company moderates the positive role of eco-innovation on employment growth, while young firms not belonging to a group (eco-entrepreneurs) contribute more to employment growth than old firms belonging to a parent firm. Implications for scholars, managers and policy makers in terms of sustainable and economic growth are made.
The Vulnerability of Coastal Tourism Destinations to Climate Change: The Usefulness of Policy Analysis
Authors: Santos-Lacueva Raquel , Clavé Salvador Anton , Saladié Òscar
Published: November 2017

Climate change conditions the sustainability of coastal destinations. This paper looks at the physical conditions that determine exposure and sensitivity to and risk from climate change and explores the sociopolitical contextual factors that determine the vulnerability of destinations. We define a destination’s vulnerability to climate change as being a reduction in its attractiveness caused by climate change combined with the consequences of adaptation and mitigation strategies. To be more specific, this paper aims to discuss the linkage between policymaking and the vulnerability of coastal destinations to climate change. We look at how this vulnerability is determined by decision-making, policies and strategies and propose an innovative analytical framework to assess vulnerability using a policy analysis approach. It is our intention to combine a content analysis of policy documents with an analysis of the perceptions and opinions of the stakeholders that influence decision-making. The paper deals with the complex, multiple, dynamic and fuzzy attributes that characterize all the items that make up this kind of research: climate change (phenomenon), vulnerability (variable), policy analysis (method), policy contents and stakeholder perceptions (indicators), coastal destinations (territorial system) and tourism (activity and policy).
Exolysin Shapes the Virulence of Pseudomonas aeruginosa Clonal Outliers
Authors: Reboud Emeline , Basso Pauline , Maillard Antoine , Huber Philippe , Attrée Ina
Published: November 2017

Bacterial toxins are important weapons of toxicogenic pathogens. Depending on their origin, structure and targets, they show diverse mechanisms of action and effects on eukaryotic cells. Exolysin is a secreted 170 kDa pore-forming toxin employed by clonal outliers of Pseudomonas aeruginosa providing to some strains a hyper-virulent behaviour. This group of strains lacks the major virulence factor used by classical strains, the Type III secretion system. Here, we review the structural features of the toxin, the mechanism of its secretion and the effects of the pore formation on eukaryotic cells.

Published: November 2017

Selection of xerophils and drought tolerant plants is highly crucial in green roof techniques in the drought prone regions of Northwest China. In this study, the thermal performance under the natural conventional climate in summer was analyzed using a self-made simulation experimental platform through comparison of the internal surface temperature with and without green roofs. The distribution frequency of internal surface temperature was investigated by dividing internal surface temperature into several ranges. Statistical analysis showed that the frequency of internal surface temperature lower than 33 °C for green roofs was 91.8%, about 1.09 times higher than that for non-green roofs, and that the sum of internal surface temperature exceeding 35 °C was about one third of that for non-green roofs. The results proved that green roofs have a significant insulation effect. Moreover, the thermal insulation property of green roofs had a strong positive relation with outside temperature. The thermal insulation characteristic was improved as the outdoor temperature increased, additionally, it had a better insulation effect within two hours after irrigation.
Past, present, and future research in bipolar lichen‐forming fungi and their photobionts
Authors: Garrido‐Benavent Isaac , Pérez‐Ortega Sergio
Published: November 2017

Compared to other organisms, such as vascular plants or mosses, lichen‐forming fungi have a high number of species occurring in both northern and southern hemispheres but are largely absent from intermediate, tropical latitudes. For instance, ca. 160 Antarctic species also occur in polar areas or mountainous temperate regions of the northern hemisphere. Early interpretations of this particular distribution pattern were made in terms of vicariance or long‐distance dispersal. However, it was not until the emergence of phylogenetics and the possibility of dating past diversification and colonization events that these initial hypotheses started to be evaluated. The premise of a relatively recent colonization of the southern hemisphere by boreal lichens through long‐distance dispersal has gained support in recent studies based on either the comparison of genetic affinities (i.e., tree topology) or more robust, statistical migratory models. Still, the scarcity of such studies and a concern that taxonomic concepts for bipolar lichens are often too broad preclude the generation of sound explanations on the mechanisms and origin of such fascinating disjunct distributions.

This review provides an up‐to‐date overview of bipolar distributions in lichen‐forming fungi and their photobionts. Evidence provided by recent, molecular‐based studies as well as data on the type of lichen reproduction, dispersal ability, photobiont identity and availability, and habitat preferences are brought together to discuss how and when these distributions originated and their genetic footprints. Ideas for future prospects and research are also discussed.
Peritoneal Dialysis Catheter Removal Post-Transplant — A Rare Case of Delayed Bowel Perforation
Authors: Maxted Andrew P. , Davies Brian , Colliver Daniel , Williams Alun , Lunn Andrew
Published: November 2017

Peritoneal dialysis (PD) is a well-established form of renal replacement therapy and the practice of leaving catheters in situ post-transplantation widely accepted. We present a rare complication: a child presenting with anal protrusion of the PD catheter.

The patient is an 11-year-old boy with a background of renal dysplasia and congenital cutis laxa. Twenty-three weeks after dialysis was commenced, the patient underwent a renal transplant. Thirteen weeks post-transplant, the patient felt an unusual sensation after defecation. The curled end of the catheter was seen protruding from the anus. He was admitted, and investigations showed stable graft function, with abdominal X ray showing no free air.

Intraoperative findings showed a small perforation of the sigmoid colon sealed off by adherence of several small intestinal loops. This was repaired laparoscopically after removal of the distal part of the catheter per rectum. No peritoneal contamination was seen. He was treated with 5 days of intravenous antibiotics and gradual introduction of enteral feeds. His graft function remained stable throughout.

Timing of catheter removal varies, from the time of transplantation to over 3 months post-transplantation. Bowel perforation due to PD catheter insertion is rare and tends to occur at the time of insertion. Anal protrusion of a PD catheter in childhood is extremely rare and unrecorded in a pediatric patient with a connective tissue disorder. Our case highlights that serious complications can occur in the period between transplantation and elective PD catheter removal and that, in the immunocompromised patient, signs can be subtle.
Fast and Scalable Gaussian Process Modeling with Applications to Astronomical Time Series
Authors: Foreman-Mackey Daniel , Agol Eric , Ambikasaran Sivaram , Angus Ruth
Published: November 2017

The growing field of large-scale time domain astronomy requires methods for probabilistic data analysis that are computationally tractable, even with large data sets. Gaussian processes (GPs) are a popular class of models used for this purpose, but since the computational cost scales, in general, as the cube of the number of data points, their application has been limited to small data sets. In this paper, we present a novel method for GPs modeling in one dimension where the computational requirements scale linearly with the size of the data set. We demonstrate the method by applying it to simulated and real astronomical time series data sets. These demonstrations are examples of probabilistic inference of stellar rotation periods, asteroseismic oscillation spectra, and transiting planet parameters. The method exploits structure in the problem when the covariance function is expressed as a mixture of complex exponentials, without requiring evenly spaced observations or uniform noise. This form of covariance arises naturally when the process is a mixture of stochastically driven damped harmonic oscillators—providing a physical motivation for and interpretation of this choice—but we also demonstrate that it can be a useful effective model in some other cases. We present a mathematical description of the method and compare it to existing scalable GP methods. The method is fast and interpretable, with a range of potential applications within astronomical data analysis and beyond. We provide well-tested and documented open-source implementations of this method in C++, Python, and Julia.

Published: November 2017

We present multi-epoch Very Large Telescope/Spectro-Polarimetric High-contrast Exoplanet REsearch (VLT/SPHERE) observations of the protoplanetary disk around HD 135344B (SAO 206462). The J-band scattered light imagery reveal, with high spatial resolution (∼41 mas, 6.4 au), the disk surface beyond ∼20 au. Temporal variations are identified in the azimuthal brightness distributions of all epochs, presumably related to the asymmetrically shading dust distribution in the inner disk. These shadows manifest themselves as narrow lanes, cast by localized density enhancements, and broader features which possibly trace the larger scale dynamics of the inner disk. We acquired visible and near-infrared photometry which shows variations up to 10% in the JHK bands, possibly correlated with the presence of the shadows. Analysis of archival Very Large Telescope Interferometer/Precision Integrated-Optics Near-infrared Imaging ExpeRiment (VLTI/PIONIER) H-band visibilities constrain the orientation of the inner disk to

and

, consistent with an alignment with the outer disk or a minor disk warp of several degrees. The latter scenario could explain the broad, quasi-stationary shadowing in north-northwest direction in case the inclination of the outer disk is slightly larger. The correlation between the shadowing and the near-infrared excess is quantified with a grid of radiative transfer models. The variability of the scattered light contrast requires extended variations in the inner disk atmosphere (

). Possible mechanisms that may cause asymmetric variations in the optical depth (

) through the atmosphere of the inner disk include turbulent fluctuations, planetesimal collisions, or a dusty disk wind, possibly enhanced by a minor disk warp. A fine temporal sampling is required to follow day-to-day changes of the shadow patterns which may be a face-on variant of the UX Orionis phenomenon.
High-energy Neutrinos from Millisecond Magnetars Formed from the Merger of Binary Neutron Stars
Authors: Fang Ke , Metzger Brian D.
Published: November 2017

The merger of a neutron star (NS) binary may result in the formation of a long-lived, or indefinitely stable, millisecond magnetar remnant surrounded by a low-mass ejecta shell. A portion of the magnetar’s prodigious rotational energy is deposited behind the ejecta in a pulsar wind nebula, powering luminous optical/X-ray emission for hours to days following the merger. Ions in the pulsar wind may also be accelerated to ultra-high energies, providing a coincident source of high-energy cosmic rays and neutrinos. At early times, the cosmic rays experience strong synchrotron losses; however, after a day or so, pion production through photomeson interaction with thermal photons in the nebula comes to dominate, leading to efficient production of high-energy neutrinos. After roughly a week, the density of background photons decreases sufficiently for cosmic rays to escape the source without secondary production. These competing effects result in a neutrino light curve that peaks on a few day timescale near an energy of ∼1018eV. This signal may be detectable for individual mergers out to ∼10 (100) Mpc by current (next generation) neutrino telescopes, providing clear evidence for a long-lived NS remnant, the presence of which may otherwise be challenging to identify from the gravitational waves alone. Under the optimistic assumption that a sizable fraction of NS mergers produce long-lived magnetars, the cumulative cosmological neutrino background is estimated to be

for an NS merger rate of

, overlapping with IceCube’s current sensitivity and within the reach of next-generation neutrino telescopes.
Relationships between Characteristics of the Line-of-sight Magnetic Field and Solar Flare Forecasts
Authors: Sadykov Viacheslav M. , Kosovichev Alexander G.
Published: November 2017

We analyze the relationship between the flare X-ray peak flux, and characteristics of the polarity inversion line (PIL) and active regions (ARs), derived from line-of-sight (LOS) magnetograms. The PIL detection algorithm based on a magnetogram segmentation procedure is applied for each AR with 1 hr cadence. The PIL and AR characteristics are associated with the AR flare history and divided into flaring and nonflaring cases. Effectiveness of the derived characteristics for flare forecasting is determined by the number of nonflaring cases separated from flaring cases by a certain threshold, and by their Fisher ranking score. The Support Vector Machine (SVM) classifier trained only on the PIL characteristics is used for the flare prediction. We have obtained the following results: (1) the PIL characteristics are more effective than global characteristics of ARs, (2) the highest True Skill Statistics (TSS) values of 0.76 ± 0.03 for ≥M1.0 flares and 0.84 ± 0.07 for ≥X1.0 flares are obtained using the “Sigmoid” SVM kernel, (3) the TSS scores obtained using only the LOS magnetograms are slightly lower than the scores obtained using vector magnetograms, but significantly better than current expert-based predictions, (4) for prediction of ≥M1.0 class flares 74.4% of all cases, and 91.2% for ≥X1.0 class, can be pre-classified as negative with no significant effect on the results, (5) the inclusion of global AR characteristics does not improve the forecast. The study confirms the unique role of the PIL region characteristics in the flare initiation process, and demonstrates possibilities of flare forecasting using only the LOS magnetograms.
The Photospheric Vortex Flows during a Solar Flare
Authors: Bi Yi , Yang Jiayan , Jiang Yunchun , Hong Junchao , Xu Zhe , Qu Zhining , Ji Kaifang
Published: November 2017

The rotational motions of the photospheric magnetic flux play a role in magnetic twist transportation between the corona and the solar interior. Using observations from the Helioseismic and Magnetic Imager on board the Solar Dynamic Observatory (SDO), we found one counterclockwise and two clockwise vortex flows on the photosphere in the NOAA active region 12371 during the flare SOL2015-06-22T18:23 (M6.5). The counterclockwise vortex was located on the footpoint of the erupting hot channels observed by the Atmospheric Imaging Assembly (AIA) Telescope on board SDO. The two clockwise vortices resided on either side of the polarity inversion line. At these vortices, the impulsive and irreversible change in the photospheric vector magnetic field were detected. The resulting change in the photospheric Lorentz force provides a torque in each vortex, which has the same direction with each vortex. A magnetic field extrapolation model shows that the coronal field starting from the two clockwise vortices suffered significant shrinkage during the changeover period of the photospheric field. Moreover, some of the modeled field rooted in the counterclockwise vortex displays a pronounced expansion during the flare. These results suggest that the clockwise vortices could result from the contraction of the magnetic field lines during the flare, while the counterclockwise vortex may be attributed to the expansion of the eruptive flux rope as observed in the AIA images.
Kepler Multi-planet Systems Exhibit Unexpected Intra-system Uniformity in Mass and Radius
Authors: Millholland Sarah , Wang Songhu , Laughlin Gregory
Published: November 2017

The widespread prevalence of close-in, nearly coplanar super-Earth- and sub-Neptune-sized planets in multiple-planet systems was one of the most surprising results from the Kepler mission. By studying a uniform sample of Kepler “multis” with mass measurements from transit-timing variations, we show that a given planetary system tends to harbor a characteristic type of planet. That is, planets in a system have both masses and radii that are far more similar than if the system were assembled randomly from planets in the population. This finding has two important ramifications. First, the large intrinsic compositional scatter in the planet mass–radius relation is dominated by system-to-system variance rather than intra-system variance. Second, if provided enough properties of the star and primordial protoplanetary disk, there may be a substantial degree of predictability in the outcome of the planet formation process. We show that stellar mass and metallicity account for of order 20% of the variation in outcomes; the remainder is as yet unknown.
Réflexions sur la psychanalyse en Argentine (1930-1955)
Authors: Balán Jorge , Artaloytia Pilar
Published: November 2017

À partir de la littérature récente sur de la création de la première association psychanalytique argentine en 1942, nous montrons que 1) le mouvement psychanalytique en Argentine a eu des racines locales, certaines initiatives des années 30 ayant reçu un soutien ambivalent de personnalités du champ de la psychiatrie. 2) Ladite association s’est démarquée clairement du passé en introduisant une formation professionnelle avec des standards internationaux. 3) L’APA a réussi à garder une place hégémonique dans le champ psychanalytique durant de nombreuses années. L’ambiance informelle qui régnait dans l’association, combinée au pouvoir grandissant des analystes didacticiens, a permis la négociation portant sur les différences internes, dans une période où les opportunités professionnelles dans le secteur public étaient très limitées, en raison d’un climat politique restrictif.
Enfance, adolescence et droits de l’homme
Authors: Viñar Marcelo , Cerutti Silvia
Published: November 2017

Cet article tisse des liens entre trois sujets cruciaux : enfance, adolescence et droits humains, en étudiant les points les plus problématiques entre eux et en proposant le rétablissement d’une dialectique entre savoir académique et engagement citoyen. Cet article analyse à partir des récits tirés de situations réelles la situation des enfants disparus pendant les dictatures et celle des enfants de la rue, en abordant la question de la transmission psychique entre générations en tant qu’agent de l’histoire comme de la structuration psychique et de la construction identitaire. Ce faisant, cet article fait référence à la place de l’analyste dans ce processus, différente de celle du politique-social.

À travers une lecture de certains moments cruciaux de la réflexion sur la communication, une tradition d’études étendue de l’esthétique du romantisme jusqu’à la théorie des médias, cet article reconstruit un réseau linguistique et conceptuel (circonstances, habitus, persona, choc, temps, représentation, conscience et allégorie), au sein duquel se trouve une redéfinition des rapports qui s’instaurent entre les médias et la perception à la fois sur le plan esthétique et sociologique.
Le cinéma de Ruy Guerra et ses racines dans l’imaginaire tragique de Dionysos
Authors: Portanova Barros Eduardo
Published: November 2017

Le rêveur qui vécut le Cinema Novo et celui qui vit la postmodernité est le même. Un rêveur qui lutte pour la poésie et pour l’acte de créer. C’est une triple lutte : contre lui, de lui contre l’Autre et de l’Autre contre lui-même. Le temps et l’espace, selon Ruy Guerra, sont la mesure de toute chose. Et c’est en syntonie avec le Cosmos – dans le cadre existentiel – que Guerra filme, cherchant un sens dans la dimension temporelle et spatiale du cinéma.
Mort d’Ashley Smith : entre bio-politique carcérale et souveraineté judiciaire
Authors: Murray Stuart J. , Burgess Sarah , Holmes Dave
Published: November 2017

Cet article constitue une relecture critique des circonstances entourant la mort d’Ashley Smith, une jeune femme décédée des causes d’asphyxie par auto-strangulation alors qu’elle avait été placée en isolement administratif par le Service correctionnel du Canada (SCC). La mort de Smith a été qualifiée d’« homicide » par un jury à la suite de l’enquête du coroner pour ensuite être qualifiée de « suicide » par le Service correctionnel du Canada (SCC) dans sa réponse aux conclusions de l’enquête. La confusion qui règne au sujet de la cause précise de la mort d’Ashley Smith sème le doute sur la ou les personnes responsables de la mort de Smith dont le décès ne peut être que le résultat d’une action directe, d’une part, ou un drame attribuable à une négligence systémique, d’autre part. En s’appuyant sur la distinction théorique-historique, proposée par Michel Foucault, entre pouvoir souverain et biopolitique, notre analyse montre que la mort de Smith est un effet de pratiques biopolitiques ayant cours au sein des établissements correctionnels. Nous estimons par ailleurs que la réponse du Service correctionnel du Canada aux conclusions de l’enquête montre de manière flagrante comment le SCC esquive ses responsabilités : il invoque une prérogative juridique (et souveraine) sur les personnes dont il a la garde, et ce dans le but de masquer ses implications bio-politiques.
Directeurs artistiques et administratrices : une distribution sexuée des rôles dans les compagnies de théâtre indépendantes
Authors: Proust Serge
Published: November 2017

Les administratrices culturelles assument des tâches essentielles permettant la viabilité matérielle des (petites) entreprises artistiques mais leur travail reste massivement invisible. Ces femmes sont inscrites dans un lien de subordination avec des directeurs artistiques, la plupart du temps des hommes, qui combinent légitimité artistique et autorité sociale. Alors que leurs multiples tâches continuent d’être perçues à travers le prisme de l’activité domestique, elles se conforment aux exigences des champs artistiques dont celles qui conduisent à la confusion des temps et des espaces sociaux. Mais, elles ne bénéficient pas des mêmes gratifications matérielles et surtout symboliques monopolisées par les artistes. C’est pourquoi, tout en étant conduites à accepter une série de compromis, les administratrices tendent à réintroduire les règles et les principes de la société salariale.
Genre et pratiques journalistiques dans la presse vtt
Authors: Fraysse Mélie , Mennesson Christine
Published: November 2017

Cet article s’intéresse aux différentes façons de faire le genre dans un contexte où la domination masculine s’exerce pleinement, celui de la presse spécialisée de vélo tout terrain ( vtt ). En mobilisant les concepts de « régime de genre » et de « masculinité hégémonique » (voir Raewyn Connell, en 1983 et 1987), il s’agit d’analyser les différentes formes de masculinités et de féminités « journalistiques » présentes au sein des rédactions des magazines de vtt , mais également d’étudier les conditions sociales qui prévalent à leur construction. Si le régime de genre étudié valorise la masculinité hégémonique et l’ emphasized feminity , certains enquêtés adoptent cependant des pratiques professionnelles qui questionnent ces modèles de genre. Les modes de socialisation professionnelle jouent un rôle central dans ce processus.
Incidence of Heterotopic Ossification Following a Multimodal Pain Protocol in Total Hip Arthroplasty With the Posterior Approach
Authors: White Peter B. , Ramkumar Prem N. , Meftah Morteza , Ghazi Narges , Ranawat Amar S. , Ranawat Chitranjan S.
Published: November 2017

Heterotopic ossification (HO) is prevalent after total hip arthroplasty (THA). Oral nonsteroidal anti-inflammatory drugs and cyclooxygenase-2 (COX-2) inhibitors have reduced the incidence of HO; however, to the authors' knowledge, no studies have reported the incidence and severity of HO with a pain protocol highlighted by celecoxib in the pre- and postoperative period with a posterolateral approach. Between October 2014 and October 2015, a retrospective study was conducted of 687 consecutive primary THAs with minimum 1-year follow-up performed between January 2009 and December 2013. All patients underwent a posterolateral THA with a multimodal pain protocol consisting of preoperative celecoxib; local steroid infiltration intraoperatively; postoperative celecoxib, dexamethasone, and ketorolac; and aspirin or warfarin thromboprophylaxis. For all patients, pre- and postoperative radiographs were examined and classified for HO using the Brooker classification. Interobserver reliability was calculated for both incidence of HO and Brooker classification. Overall, HO was present around 98 (14.3%) THAs. The incidence of Brooker I, II, and III HO was 38 (5.5%), 47 (6.8%), and 12 (1.7%), respectively. No patients required surgical excision or had radiographic evidence of Brooker IV HO. Multivariate logistic regression identified male sex and hypertrophic osteoarthritis as significant risk factors. The use of aspirin for thromboprophylaxis significantly reduced the incidence of HO. This study found the overall incidence of HO when using celecoxib during a posterior THA to be 14.3%, which is similar to what others have reported with the direct lateral approach and with other COX-2 inhibitors for a posterior approach. Risk factors include male sex and preoperative hypertrophic osteoarthritis. [

Peripheral Neuropathy Due to Recreational Use of Nitrous Oxide Presenting After an Ankle Sprain With Foot Drop
Authors: Middleton Jackson A. , Roffers John A.
Published: November 2017

A 22-year-old man was referred for orthopedic follow-up after an ankle injury. Initial evaluation in urgent care included radiographs with negative findings. After a delayed presentation, a course of functional treatment was recommended. Subsequently, he developed a deep venous thrombosis and pulmonary emboli. He was found to be factor V Leiden deficient and was fully anticoagulated on warfarin. Later reevaluation revealed a steppage gait and foot drop. Electrodiagnostic studies (ie, electromyography and nerve conduction studies) revealed a severe peripheral polyneuropathy. The patient admitted to engaging in high-volume recreational use of nitrous oxide. Neurological evaluation confirmed vitamin B12 deficiency consistent with the toxic effects of nitrous oxide. The patient's condition improved with vitamin B supplementation, bracing, and avoidance of nitrous oxide and similar neurotoxins. He participated in a 3-month physical rehabilitation program, and he displayed partial recovery at most recent follow-up. [

Nerve Traction Injury After Subacute Revision External Fixation of a Tibial Plateau Fracture
Authors: Wessel Lauren E. , Christ Alexander B. , Helfet David , Wellman David S.
Published: November 2017

Nerve traction injuries are common clinical entities that can be confused with nerve palsies secondary to alternate etiologies. Common mechanisms of nerve injury include direct laceration, crush injury, compression injury, elevated compartment pressures, or traction injury. Traction injuries commonly occur after trauma or aberrant patient positioning; however, traction injury following external fixation for lower extremity injury is rare. This case report describes a 42-year-old man who initially sustained a Schatzker VI tibial plateau fracture that required revision of external fixation for pin-site infection as soft tissues recovered from the initial trauma. Postoperatively, the patient experienced a nerve traction injury from lengthening after revision external fixation. Acute loss of common peroneal motor and sensory function was identified 1 hour postoperatively in the post-anesthesia care unit; this reversed on the immediate release of distraction from the external fixation construct. The patient's clinical course and the basic science principles underlying nerve traction injuries are discussed. Although traction injuries are rare after external fixation, orthopedic clinicians must understand them because early recognition can optimize outcomes. Knowledge of the biomechanical properties of peripheral nerves and their mechanisms of injury in such clinical settings may be useful for recognizing patients at risk for nerve traction injuries. [

Optical Coherence Tomography Findings in Endogenous Fungal Chorioretinitis, Retinitis, and Endophthalmitis
Authors: Stephens John D. , Adam Murtaza K. , Todorich Bohzo , Faia Lisa J. , Garg Sunir , Dunn James P. , Mehta Sonia
Published: November 2017

BACKGROUND AND OBJECTIVE:

To describe spectral-domain optical coherence tomography (SD-OCT) findings in eyes with endogenous fungal chorioretinitis and endophthalmitis.

PATIENTS AND METHODS:

Retrospective, observational case series of subjects at Wills Eye Hospital and William Beaumont Hospital were identified by screening OCT billing data and cross-referencing with patient charts. Clinical and imaging data were collected for each patient and reviewed.

RESULTS:

Twelve eyes of seven consecutive patients were identified, demonstrating two patterns of posterior ocular involvement: chorioretinal infiltration and superficial retinal/retinal vascular infiltration without choroidal involvement. Six of 12 eyes had follow-up imaging performed after antifungal treatment, which demonstrated decreased size of choroidal and/or retinal infiltrates.

CONCLUSIONS:

All patients with follow-up imaging had anatomic improvement by OCT of the lesions with treatment. In the future, OCT imaging may provide a method to assess therapeutic response and prognosis for visual recovery in patients with endogenous fungal ocular disease.

Single-Spot Yellow Laser Versus Conventional Green Laser on Panretinal Photocoagulation: Patient Pain Scores and Preferences
Authors: González-Saldivar Gerardo , Rojas-Juárez Sergio , Espinosa-Soto Itzel , Sánchez-Ramos Jorge , Jaurieta-Hinojosa Noel , Ramírez-Estudillo Abel
Published: November 2017

BACKGROUND AND OBJECTIVE:

Panretinal photocoagulation (PRP) is the mainstay therapy for proliferative diabetic retinopathy. Pain during and after its application is a complication that affects patients' therapeutic adherence. This study aimed to compare pain perception and patient preference for the 577-nm yellow laser (YL-577) (LIGHTL as 577; LIGHTMED, San Clemente, CA) and the conventional 532-nm green laser (GL-532) (Purepoint Laser; Alcon, Fort Worth, TX) with PRP.

PATIENTS AND METHODS:

A total of 92 patient eyes with proliferative diabetic retinopathy treated with PRP were randomly assigned to receive both GL-532 and YL-577 (184 eyes) — one on each eye, with the order of application randomized, as well. Afterward, verbal rapid answer and visual analogue scale (VAS) scores for pain perception and patient preference were evaluated.

RESULTS:

VAS score was 7 ± 2 for the GL-532 group compared to 5 ± 3 in the YL-577 group (
P
= .001). Overall, 75% of the patients preferred YL-577 therapy if they were to receive a second PRP session.

CONCLUSION:

The use of YL-577 as an alternative approach for PRP reduces pain perception and is preferred by patients.

Quantitative Choriocapillaris Perfusion Before and After Vitrectomy in Idiopathic Epiretinal Membrane by Optical Coherence Tomography Angiography
Authors: Yu Yanping , Teng Yufei , Gao Meng , Liu Xinxin , Chen Jinqiu , Liu Wu
Published: November 2017

BACKGROUND AND OBJECTIVES:

To compare choriocapillaris perfusion of the fovea between patients with idiopathic epiretinal membrane (iERM) and normal controls and determine whether surgery affects it.

PATIENTS AND METHODS:

Both eyes of 45 patients with iERM and 28 healthy subjects were scanned by optical coherence tomography angiography (OCTA) preoperatively, and 25 of the patients were scanned postoperatively. Central parameters measured included flow area and parafovea vessel density of the foveal choriocapillaris.

RESULTS:

Both parameters were significantly lower in eyes with iERM (both
P
< .001) compared with both the unaffected fellow eyes and the normal control eyes (both
P
< .001) preoperatively, and they increased as the result of surgery, although it did not reach statistical significance. However, the differences between both eyes of patients became insignificant after surgery (both
P
> .05).

CONCLUSIONS:

OCTA may provide quantitative information regarding choriocapillaris perfusion. iERM influences the foveal choriocapillaris perfusion, which is reversible by surgery.

Religious Tourism Experience Model (RTEM)
Authors: Ramos Célia M. Q. , Henriques Cláudia , Rodrigues João M. F.
Published: November 2017

Information and Communication Technologies (ICT) have established a growing and deeper interconnection alliance with the tourism sector. Few solutions have contributed to the dissemination of cultural and religious heritage of the regions, as a means of promoting it, making known and enriching the culture of its visitors and residents. The development of an intelligent application that allows the dissemination of cultural and religious heritage can bring new experiences and sensations for tourists and for residents in general, and for those with accessibility problems in particular. The present chapter proposes a methodological framework for the development of a recommendation system associated with the Religious Tourism Experience Model (RTEM), with the objective of identifying and selecting consumer preferences for the dissemination of cultural heritage in general, and religious heritage in particular.

Technological advances have had an impact on many industries as well as the tourism industry. Augmented reality applications, one of the emerging new technologies in recent years, have also started to be used in our daily lives. Augmented Reality (AR) is a technology that allows its users to see the real world together with an additional virtual world that is added in real time to the same field of view. The augmented reality applications contribute to the enrichment of tourists' tourism experiences, especially during their visit and result in augmented satisfaction levels. Furthermore, it is one of the effective tools that can be used against the wear and tear of cultural heritage sites caused by overcrowding. In this chapter, the application fields of the augmented reality in the field of tourism have been discussed under the subtitles. As a result of our study, recommendations for the development of AR applications both for the literature and real-life application have been presented.

Accurate modeling/reconstruction and visualization of real environments, particularly archaeological sites, is both a major challenge and a crucial task. This work will address the entire process of the virtual reconstruction of archaeological sites, since the construction of the virtual model until its visualization. The chapter begins with an introduction to the process of virtual reconstruction of archaeological sites, where the several stages that should take place to obtain a faithful virtual representation of an archaeological site and its artifacts are identified. Moreover, each stage is characterized and its main methods and techniques are identified, in dedicated sections. The authors' contribution for the state of the art will be highlighted in each stage. The chapter ends with the authors' vision about future trends for this field and unveils what could be their contributions to this vision.
Storytelling in Cross-Media Advertising
Authors: Kurultay Ayse Binay
Published: November 2017

Multi-platform communication is becoming the norm as media practice has been changing with the growth of technologies that put viewers in more control and introduce interactivity. This chapter focuses on the Turkish cross-platform advertising campaign, Tweet Village for Sekerbank that received a bronze prize in 2015 at Cannes Lions, which is globally regarded as the most important festival in the field of creative communication. The campaign focused on thousands of family farmers who quit farming to migrate to urban cities in order to support those who resisted leaving. The campaign involves multiple platforms, such as social media, print advertisements, outdoor advertisements and radio spots which make it a successful case for explaining the use of storytelling in cross-media advertising. The case of Tweet Village was evaluated through Berger's (2013) criteria for sharing the campaign's message online as well as Chiu et al.'s (2012) brand story elements.
Applying Hybrid Interactive Rhetoric Engagement (H.I.R.E.) Concept to Study Digital Game Advertising
Authors: Kang Yowei
Published: November 2017

Among many popular digital game platforms, MMORPGs is a popular game genre that attracts a lot of attention. Companies have increasingly used digital game platforms to target young gameplayers. In examining digital games in general and MMORPGs in particular, digital game and advertising scholars often conceptualize gamers' interactions with hybrid interactive contents in advertising embedded in digital game platforms as an object that can be studied and analyzed to develop a theory of intertexuality to understand its praxix as demonstrated in this popular advertising platform. This chapter introduces the concept of hybrid interactive rhetorical engagement (henceforth, H.I.R.E.)—to examine players' multi-modal interactions as intertextual objects when they interact with digital game advertising. The chapter examines how H.I.R.E. can be applied to study the intertextuality of digital game advertising by exploring its theoretical and methodological implications for digital game as well as intertextuality scholars.
Attribution Modeling in Online Advertising
Authors: Schultz Carsten D. , Dellnitz Andreas
Published: November 2017

In correspondence with the increased use of the information and communication technology, companies have adopted various measures of online advertising and have continuously increased the online advertising spending. The technology enables companies to monitor and steer their advertising activities and generally allows to register all (online) touchpoints of a prospect with a company, the so-called customer journey. As one prospect may have multiple contacts with a brand, advertisers have to analyze how different touchpoints contribute to the advertising success. Advertisers may use a variety of heuristic and analytic attribution models. This chapter presents and discusses the most relevant attribution models – heuristic and analytic variants. Heuristic attribution models are simple rule-based approaches, whereas analytic attribution models infer the impact of different marketing channels across customer journeys and calculate the probability of a successful customer journey. Then, some business implications and potential pitfalls of attribution models are discussed.

Low density regions face many development challenges. In the Alentejo region of Portugal, and in many other Southern European regions, such challenges have been intensified by the cumulative effects of the financial and economic crises, and the subsequent austerity. In such context, and to promote region catching up and sustainable development, a number of policies designed to promote local entrepreneurial ecosystems have been reinforced. In this study, we focus on one of these policies' instruments – business incubation - and on the region of Alentejo, and describe five incubators implemented by a local regional development association (ADRAL), some municipalities, a national association of young entrepreneurs (ANJE), and a local association of entrepreneurs (NERE). We assess the incubators' distinctive characteristics and those of some incubated projects, aiming at identifying the specificities of this approach and its success determinants.
Social Entrepreneurship and Entrepreneurial Ecosystems
Authors: Bernardino Susana , Santos J. Freitas , Ribeiro J. Cadima
Published: November 2017

Entrepreneurial ecosystems and social entrepreneurship are receiving increasing attention for their ability to foster economic and social development. This study adopts the entrepreneurial ecosystem approach to analyse the extent to which the perceived favourability of external environment promotes or deters the launch of new ventures by social entrepreneurs. The research was based on a survey that collected data through a questionnaire emailed to Portuguese social entrepreneurship ventures. The results show that a favourable entrepreneurial ecosystem has low importance in the decision to develop new social ventures. This result is particularly consistent in more innovative social ventures. This conclusion supports the idea that many social ventures are not based on social innovation, but derive from a traditional approach to social problems. Therefore, the development of new innovative social ventures has to be supported by institutional stakeholders in order to support social entrepreneurs, regardless of the level of favourability of the entrepreneurial context.
Analysing Innovation in Healthcare Organizations
Authors: Rua Orlando Lima , Correia Maria João
Published: November 2017

The main purpose of this study is to analyse innovation in organizations of the Portuguese healthcare sector, in order to identify its critical success factors. In this study, we followed a quantitative approach, combining statistical and documental analysis, through the Community Innovation Survey data analysis and processing, thus performing an exploratory, descriptive and transversal study. The healthcare sector reveals dynamism in introducing products that are new to the market and the company, mainly through a closed innovation process. External cooperation is preferably R&D-oriented, and there is low involvement of market agents in R&D activities, through partnerships. However, these are seen as an important source of information and organizations seek to meet their needs. Different types of organizations adopt different innovation strategies, depending on their market and current situation, which translates into a contextual innovation policy, in line with the current theoretical developments.

Published: November 2017

Due to the rising importance of the global interdependence, decisions related to supplier selection rely on not only corporate operation conditions, but also corporate social responsibility (CSR). Under this circumstance, this chapter focuses on a supplier selection problem concerning CSR. Particularly, seven criteria and their corresponding importance for supplier selection are analyzed. Meanwhile, some relevant sub-criteria are included as well. Based on existing literature review and managerial interviews obtained from leaders in the southern region of India, these issues are compared and ranked. In this chapter, Analytical Hierarchy Process (AHP) is conducted to identify the importance of these considered criteria and sub-criteria. Finally, the chapter concludes with a presentation of rankings and priorities of the proposed seven criteria. Given the obtained results and recommendations, it would be helpful to establish a useful method for selecting the best supplier based on CSR.
