Orthogonal Chirp Division Multiplexing for Underwater Acoustic Communication
Authors: Bai Yiqi , Bouvet Pierre-Jean
Published: November 2018

The objective of this study is to investigate a novel Underwater Acoustic Communication (UWAC) system based on a modulated chirp signal termed as Orthogonal Chirp Division Multiplexing (OCDM). Originating from the Fresnel transform, OCDM uses chirp signals to exploit the multipath diversity of the channel, achieving a good robustness against frequency fading, especially in the underloaded scenario where only a subset of the available waveforms is modulated. The implementation of the OCDM system for the UWAC scenario is described, and the performance results over an experimental water tank and realistic replayed underwater channel are compared against the traditional Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme.
Touching Queerness in Disney Films Dumbo and Lilo & Stitch
Authors: Perea Katia
Published: November 2018

Disney’s influence as a cultural purveyor is difficult to overstate. From cinema screen to television programming, vacation theme parks to wardrobe, toys and books, Disney’s consistent ability to entertain children as well as adults has made it a mainstay of popular culture. This research will look at two Disney films, Dumbo (1941)1 and Lilo & Stitch (2002),2 both from distinctly different eras, and analyze the similarities in artistic styling, studio financial climate, and their narrative representation of otherness as it relates to Queer identity.
Parameter Estimation of Wormholes beyond the Heisenberg Limit
Authors: Sanchidrián-Vaca Carlos , Sabín Carlos
Published: November 2018

We propose to exploit the quantum properties of nonlinear media to estimate the parameters of massless wormholes. The spacetime curvature produces a change in length with respect to Minkowski spacetime that can be estimated in principle with an interferometer. We use quantum metrology techniques to show that the sensitivity is improved with nonlinear media and propose a nonlinear Mach–Zehnder interferometer to estimate the parameters of massless wormholes that scales beyond the Heisenberg limit.
Phytochemical Molluscicides and Schistosomiasis: What We Know and What We Still Need to Learn
Authors: Augusto Ronaldo de Carvalho , De Mello-Silva Clelia Christina Correa
Published: November 2018

Worldwide schistosomiasis remains a serious public health problem with approximately 67 million people infected and 200 million at risk of infection from inhabiting or transiting endemically active regions. Africa, South America, the Caribbean, and the Middle East are the main transmission regions of Schistosoma mansoni. The fight against transmission through the use of molluscicides is not recent and has been advocated as the only activity with the possibility of interruption of transmission in small, epidemiologically active outbreaks. Euphorbia milii var. hislopii (syn. splendens) (Des Moulins, 1826) is the most promising for use in official schistosomiasis control programs according to the WHO. In this review, we show that an understanding of some how E. milii latex affects the snail vector and their parasites from a molecular level to field conditions is lacking. On the other hand, this type of treatment could also provide a rationale for the control of schistosomiasis and other parasitosis. Several publications contribute to enforcing the use of E. milii latex in endemic countries as a cheap alternative or complement to mass drug treatment with praziquantel, the only available drug to cure the patients (without preventing re-infection).
Formation des réseaux karstiques et creusement des vallées : l'exemple du Larzac méridional (Hérault, France)
Authors: Camus Hubert
Published: November 2018

Speleogenesis and valleys : the south Larzac (Herault, France). The Causses and mediterranean Garrigues present a long continental evolution from late Cretaceous. The karstic network analysis and the dynamic study give geomorphological indicators to reconstruct the paleogeography of this area when the geological indicators are not present. The paleoclimatic action and the tectonic movements make the actual landscape melting a lot of ages and genesis different elements. The endokarst preserves sedimentological and paleoclimatic witnesses and also hollowing shapes that traduce the successiv steps of the paleogeographic evolution. The network's levels of the South Larzac are connected with the landscape karstic forms : poljes, canyons, peripheric valleys. The reef limestone of the Séranne and the dolomite of the Monts de St Guilhem explain this good conservation of the endokarst and of the landscapes.
Les recoupements karstiques de méandres encaissés

Published: November 2018

The karstic cut-off of incised meanders. Three types of cut-off can be observed : 1) by natural bridge or short tunnel : Pont d'Arc type self-piracy (Ardèche, France) ; 2) by caves system or hydrogeological network, Lesse type (Ardenne, Belgium) ; 3) subaerial in karstic environment, the case of Vis in Navacelles (Hérault, France). The main processes are debated : anteriority or/and coexistence of the underground drainage, impact of neotectonics, of the load and the screes and of the water chemistry changes.
Dissipation d'énergie et adaptabilité dans les systèmes karstiques
Authors: Quinif Yves
Published: November 2018

Energy dissipation and adaptability in the karst systems. The phenomenon of karstifïcation and even the term "karst" have been studied extensively but the concepts used explain only partially this complex problem. In this paper is proposed a global thermodynamic and geological approach to karstifïcation. The universal thermodynamic concepts - energy dissipation and entropy variation - are first studied. In the second approach the karstic systems are studied in their geological and geomorphological environment.
Les apports de l'endokarst dans la reconstitution morphogénique d'un karst, exemple de l'Antre de Vénus (Vercors, France)
Authors: Delannoy Jean-Jacques , Caillault Serge
Published: November 2018

Les études menées ces dernières années sur l'endokarst ont démontré que les cavités comportent de nombreuses informations sur l'évolution hydrogéologique, géomorphologique, tectonique et climatique d'un massif calcaire. Les nombreux articles présentés dans Karstologia et d'autres revues sont l'expression de cette «nouvelle» approche de la spéléologie.

Cet article a, ici, pour objet de mettre en évidence la portée paléogéographique de l'endokarst à partir de simples observations des formes, des dépôts souterrains et de leur relation. L'étude de l'Antre de Vénus permet de reconstituer une ancienne géographie du Vercors, bien antérieure au creusement des gorges de la Bourne qui commande l'essentiel de l'organisation "actuelle" des écoulements souterrains de ce massif.
Adsorption of Organic Molecules on Onion-like Carbons: Insights on the Formation of Interstellar Hydrocarbons
Authors: Qi Haonan , Picaud Sylvain , Devel Michel , Liang Enwei , Wang Zhao
Published: November 2018

Using atomistic simulations, we characterize the adsorption process of organic molecules on carbon nanoparticles, both of which have been reported to be abundant in the interstellar medium (ISM). The aromatic organics are found to adsorb more readily than the aliphatic ones. This selectivity would favor the formation of polycyclic aromatic hydrocarbons (PAHs) or fullerene-like structures in the ISM due to a structural similarity. In our simulations, we also observed that the molecules form a monolayer over the nanoparticle surface before stacking up in aggregates. This suggests a possible layer-by-layer formation process of onion-like nanostructures in the ISM. These findings reveal the possible role of carbon nanoparticles as selective catalysts that could provide reaction substrates for the formation of interstellar PAHs, high fullerenes, and soots from gas-phase molecules.
Une opération à cœur ouvert sous acupuncture ? Décryptage d’une émission diffusée sur France 2
Authors: Darbois Nelly , Evain Jean-Noël , Guillaud Albin , Lilot Marc , Pinsault Nicolas
Published: November 2018

Objectifs : Analyser une séquence de l’émission télévisée « Acupuncture, ostéopathie, hypnose : les médecines complémentaires ont-elles de super-pouvoirs ? », présentant un exemple d’« une opération à cœur ouvert, avec une anesthésie sous acupuncture » pratiquée dans un hôpital chinois. Proposer une explication plus rationnelle des phénomènes observés. Décrire les processus amenant une chaîne du service public audiovisuel à proposer ce type de séquence à une heure de grande écoute et les conséquences potentielles en matière de santé publique. Méthode : Analyse critique utilisant des principes et outils rationnels, accompagnés d’une recherche bibliographique sur les bases de données Medline , Google Scholar et Cochrane Library . Résultats : Les informations délivrées dans la séquence sont ambiguës et ne permettent pas de se faire un avis éclairé sur l’intérêt de l’acupuncture pour une chirurgie à cœur ouvert. Il est raisonnable de penser que la séquence montre une chirurgie pratiquée avec anesthésie péridurale non avouée, couplée à une sédation intraveineuse légère. La particularité est ici la surestimation de l’effet spécifique de l’acupuncture ajoutée au protocole. Les médias ont en effet tendance à exagérer les risques et les effets attendus des traitements sur lesquels ils communiquent, ce qui peut conduire les patients à se tourner vers des thérapies non éprouvées. Conclusion : La diffusion d’une telle séquence à une heure de grande écoute souligne l’impérieuse nécessité pour le grand public mais aussi et surtout les professionnels de santé d’être formés au tri et à l’analyse critique des informations en matière de santé.
Approche centrée sur le patient et nouvelle gestion publique : confluence et paradoxe
Authors: Sebai Jihane , Yatim Fatima
Published: November 2018

La recherche de l’efficience et la concentration sur les besoins du patient et sur sa satisfaction sont au cœur des conceptions actuelles en termes de qualité et d’organisation des services de santé. On constate, en effet, une relative consolidation des approches organisationnelles dites Patient-Centred Care (ex. CCM, DM, Case management, population management ) pour une prise en charge structurée des patients atteints de maladies chroniques et une réelle volonté de leur mise en place dans le domaine de la santé. Cette évolution se prolonge au niveau du pilotage des systèmes de santé à travers le New Public Management – NPM. Une forte pression pèse ainsi sur les professionnels (professionnels du soin et gestionnaires) appelés à assurer une plus grande efficacité en termes d’activités et une plus grande efficience en termes d’usage des moyens. Les deux évolutions vont dans le sens d’une plus grande place accordée à la personnalisation des prises en charge, à la différenciation des prestations et à la prise en compte de la satisfaction des bénéficiaires des services publics. Toutefois, sans être antinomiques, les deux évolutions sous-tendent des ressorts et des mécanismes divergents, voire paradoxaux.

Customized LASIK Treatment for Myopia Based on Preoperative Manifest Refraction and Higher Order Aberrometry: The Rochester Nomogram
Authors: Subbaram Manoj V , MacRae Scott M
Published: November 2018

ABSTRACT

PURPOSE: To develop and test the efficacy of myopic treatment, based on preoperative manifest refraction and higher order aberrations, in enhancing the postoperative refractive error following customized LASIK treatment and compare results with the manufacturer-recommended sphere offset Zyoptix treatment nomogram, which does not account for the preoperative higher order aberrations.

METHODS: One hundred seventy-five myopic eyes (89 patients) were treated based on the Rochester nomogram, which specified the amount of myopia to be treated based on preoperative manifest refraction and higher order aberrations, including third order aberrations and spherical aberration. Postoperative refractive error was measured at 1 month and compared to that theoretically estimated with the Zyoptix nomogram.

RESULTS: The mean preoperative sphere and cylinder were -4.52±2.05 diopters (D) and -0.81±0.70 D, respectively. The mean postoperative spheres were +0.04±0.33 D and +0.31±0.54 D, using the Rochester and Zyoptix nomograms, respectively. The mean postoperative spherical equivalent refractions were -0.11±0.34 D and +0.15±0.53 D using the Rochester and Zyoptix nomograms, respectively. The Rochester nomogram reduced the range of postoperative spherical equivalent to ±1.00 D, which was significantly better than that using the Zyoptix nomogram (t=5.46, P<.0001), which would have resulted in 8% of eyes with a postoperative spherical equivalent refraction >±1.00 D. Using the Rochester nomogram, 93.1% of eyes attained a postoperative UCVA ≥20/20. The percentage of postoperative hyperopic overcorrection decreased to 2.8% in the Rochester nomogram group from 22.3% using the Zyoptix nomogram, which only adjusts spherical values based on preoperative sphere and does not account for preoperative aberrations.

CONCLUSIONS: The Rochester nomogram compensates for the effect of preoperative higher order aberrations on sphere and provided reduced range of postoperative spherical equivalent refraction. [J Refract Surg. 2007;23:435-441.]
Caminhadas urbanas, com-vivências inesperadas
Authors: Fortuna Carlos
Published: November 2018

O aceleracionismo urbano de hoje torna anacrónico o ato de caminhar na cidade. A deslocação rápida dos sujeitos gera um modo distraído de interpretação dos territórios urbanos e das relações que nele se operam. No século xx, as célebres passeatas urbanas (Dada, Surrealistas, Situacionistas, flânerie) procuraram reconhecer a presença de outras culturas e modos de existência. Todas as caminhadas na cidade podem originar relações inesperadas em público, que vão desde as solidariedades espontâneas até ao reconhecimento de desigualdades e racismos. Tudo reclama pela centralidade da rua, o que pode ser comprovado através de uma caminhada pelas ruas e praças de Lisboa.
Revolução, história e memória – O 25 de Abril e os desafios da História Oral
Authors: Cruzeiro Maria Manuela
Published: November 2018

A complexidade do fenómeno revolucionário em geral (e igualmente do 25 de Abril de 1974 em Portugal) exige uma abordagem metodológica que ultrapasse as dificuldades e limitações da historiografia clássica. Neste contexto, a História Oral vem assumindo uma importância crescente (também em Portugal), mostrando que ficamos muito mais próximos do acontecimento revolucionário, se à memória histórica e aos seus principais garantes, os arquivos, juntarmos a memória individual. Se ao registo exaustivo de factos, nomes ou datas, juntarmos as vozes de quem viveu essa experiencia única – dos principais protagonistas às figuras secundárias ou mesmo passivas – captamos ambientes, formas de pensar, valores, racionalidades e sensibilidades. É esse o grande desafio da História Oral, como pretendemos mostrar neste artigo.

En mêlant ethnographie, archéologie, sciences cognitives et histoire, ce numéro entend montrer la fertilité actuelle de l’anthropologie de l’écriture. Ses auteurs se tiennent à distance des grands récits qui font de l’écriture l’accoucheuse de la Raison ou encore un outil coercitif entre les mains de l’État. Ils préfèrent montrer comment l’écrit ne cesse de changer de fonctions, par un processus de constant recyclage. Des codes graphiques qui n’étaient pas faits pour noter une langue acquièrent un sens linguistique ; des motifs décoratifs sont reconvertis en lettres, et inversement ; les emblèmes du pouvoir se font objets de culte.
Acute Tubulointerstitial Nephritis and Polyclonal Hypergammaglobulinaemia: Which Is the Culprit?
Authors: Sirvent Ana E. , Enríquez Ricardo , Muci Tania , Ardoy-Ibañez Francisco Javier , Millán Isabel , Almiñana Amadeo , Ruiz-Ferrús Rosalía , del Cerro Luis Jiménez
Published: November 2018

Proton pump inhibitors (PPIs) are among the most frequent implicated drugs in acute tubulointerstitial nephritis (ATIN), nevertheless it is important to report cases with atypical profiles. A 80-year-old female, exposed during 34 months to omeprazole, presented with polyclonal hypergammaglobulinaemia and renal failure. After stopping omeprazole there was a partial improvement in serum creatinine and IgG. Renal biopsy revealed ATIN; immunohistochemistry for IgG4 was negative. Treatment with steroids and mycophenolate sodium improved renal function and normalized immunoglobulins. The lack of data of other entities and the patient’s evolution strongly point omeprazole as the culprit. After 27 months of follow-up, she remains clinical and analytically stable. ATIN caused by PPIs may appear after a long period of exposure and may be accompanied by analytical anomalies that simulate a systemic disease.
Transfusion-associated graft-versus-host disease: A concise review
Authors: Manduzio Palma
Published: November 2018

Transfusion-associated graft-versushost disease (TA-GVHD) represents a rare fatal event observed in immunocompromised patients and immunocompetent individuals. The main clinical features of this transfusion reaction are pancitopenia and multiorgan failure (skin, liver, gut). The possible pathogenesis includes donor T lymphocyte proliferation in blood, their engraftment and host tissue attack. The purpose of this narrative review was analyzing the international guidelines for irradiation of cellular blood components to prevent TA-GVHD. A literature search was conducted using PubMed articles published between January 2000 to July 2018. American, Australian, British and Japanese transfusion guidelines have been compared regarding clinical indications. The contribution of manuscripts has been focused on recipients of Haematopoietic Stem Cell Transplantation, severe cellular immunodeficient patients, fetuses and neonates, immunocompentent individuals. Furthermore, 348 cases of TA-GVHD in the last five decades have been documented according to a recent systematic review. The standard of care to prevent this complication is gamma or x irradiation of cellular blood products. New treatments with pathogen inactivation appear safe and effective against proliferating white blood cells and T cells. Further clinical and biological studies are necessary to better characterize immunocompetence of T cells and select alternative preventive strategies.
Capgras syndrome in substance-induced psychosis
Authors: Sampathi Bharat R. , Sofine Anna , Alvarez John , Bota Robert G.
Published: November 2018

Capgras Syndrome is a subcategory of delusional disorder. People affected by this syndrome believe that a close associate such as a friend or family member has been replaced by an identical imposter. This case report describes a 23-year-old woman with no prior psychiatric history, whom developed Capgras syndrome, via folie a deux, in the setting of poly-substance use. In this patient, a combination of Aripiprazole 10 mg daily and Escitalopram 10 mg daily were effective in resolving symptoms. Clonazepam was utilized for anxiety and Omega-3 fatty acids 1 g for anti-oxidative effects. Further studies are needed to investigate the effects of a variety of causes and treatments for Capgras Syndrome.
Culture and corruption: a critical analysis of the basis of Nigerian depraved experience
Authors: Chinweuba Gregory Emeka
Published: November 2018

Evidently, the spate of corruption in Nigeria is worrisome. This is as it has defied every leadership strategy, and has continued to eat deep into the fabric of Nigerian society. But how and why did corruption get into the Nigerian society? This paper analytically investigates the basis of corruption in Nigeria, and proffers some panacea to the prevalent corrupt practices stunting every sustainable development. The study however finds that corruption is dependent on some cultural elements which enkindle and abet it. It again discovers that since culture is the matrix of human existence and nothing happens outside it, human corrupt practices stem from cultural systems. This is more so as corrupt practices are also understood and interpreted within cultural space. The paper concludes that corruption can be retrogressed when there is a positive review of those unwholesome cultural elements prevalent in diverse cultures of Nigeria which abet corruption. This review must also extend to the place of family, clan, community and tribe in the heart of every Nigerian.Keywords: Corruption; Culture; Analysis; Deprave, Experience
Applying performance indices in plantwide modelling for a comparative study of wastewater treatment plant operational strategies
Authors: De Ketele Justine , Davister Dries , Ikumi David S
Published: November 2018

Achievement of good effluent quality is always the main goal for wastewater treatment plant (WWTP) systems. However, these WWTPs have developed further objectives that include efficient design and strategic control options, with the prospect of their conversion into waste resource recovery facilities (WRRFs) that operate on reduced energy costs. With all these aspects becoming an intrinsic part of waste treatment, mathematical models that simulate WWTP unit processes are becoming of increasing relevance for the achievement of WRRF goals (including good effluent quality, low energy costs and nutrient recovery). It is expected that these mathematical models will benefit potential future applications of automation process control, which have also been developing rapidly with the availability of more reliable and affordable sensors. However, simulated automation control strategies require a thorough evaluation protocol to ensure their viability prior to being adopted as efficient operation control measures. This study considers the comparison of different control strategies implemented on a standard WWTP layout, for plant optimization. The initial task was to define performance indices, effluent quality index (EQI) and operation cost index (OCI), based on a previous investigation by the International Water Association (IWA) benchmark simulation modelling (BSM) task group. These performance indices were then used to evaluate the following strategies: (i) adding a fermentation tank, (ii) dosing flocculant and (iii) implementing a balancing tank. A control strategy was only assumed to be effective with improvement or maintenance of effluent quality. Overall, the evaluation exercise proved to be useful for providing expert advice on efficiency of proposed waste treatment system layouts, towards determination of the best configuration of future WRRFs. For instance, it was notable that significant organic strength is needed for removal of nutrients recycled back from the anaerobic digestion (AD) system into the activated sludge (AS) – hence alternate methods to put the nutrient-rich outflow from the AD system to good use are required.
Distribution of polychlorinated biphenyl along the course of the Buffalo River, Eastern Cape Province, South Africa, and possible health risks
Authors: Yahaya A , Adeniji OA , Okoh OO , Songca SP , Okoh AI
Published: November 2018

Humans and wildlife are vulnerable to the toxicity of semi-volatile and persistent organic pollutants such as polychlorinated biphenyls (PCBs). Neither the distribution of these pollutants nor their seasonal variation has ever been determined in the Buffalo River. Thus, the occurrence and concentration of 19 PCBs was assessed in King William’s Town (KWT), Izele (IZ), Zwelitsha (ZW), Maden (MD), Mdantsane (MSN) and Buffalo River estuary (BRE), all on the Buffalo River in the Eastern Cape Province of South Africa. Water samples were subjected to liquid-liquid extraction for PCBs, after which the compounds were separated and quantified on gas chromatography with electron capture detection. The PCBs differ in concentration from below detection limit (BDL) to 482 ng·L−1 in summer and BDL to 2 383 ng·L−1 in autumn. While the order of congeners increases during the summer from KWT > IZ > ZW > MD > MSN > BRE, the distribution in autumn followed the order BRE > IZ > ZW > KWT > MSN > MD. The total levels of PCBs at all the sites during summer were below the World Health Organization (WHO) permissible level of 500 ng·L−1 recommended for humans, but were exceeded at all the sampling sites in autumn except at MD. The evaluated risk with respect to cancer was lower than the acceptable threshold (10-6), whereas hazard quotients were slightly higher than the maximum threshold (of 1) stated by the United States Environmental Protection Agency (USEPA). The compounds are known to be toxic to humans and animals. The results appear to show that the exposure levels of the compounds were safe for humans and animals. Further studies are recommended in order to make a definitive conclusion.
Development of a deterministic design model for a high-rate algal pond
Authors: Van der Merwe ISW , Brink IC
Published: November 2018

Inadequate wastewater treatment is a major problem in South Africa. Existing wastewater treatment facilities often lack sufficient skilled labour, resulting in partially treated effluent. Increasing eutrophication in surface water bodies indicates that this problem needs rectification. The characteristics of the high-rate algal pond (HRAP) technology makes it an attractive option for effluent polishing in South Africa. It has the potential of simultaneous nutrient removal and nutrient recovery from partially treated effluent. A deterministic design model based on the mutualistic relationship between bacteria and algae in an HRAP was developed. The model includes kinetics of algae, ordinary heterotrophic organisms (OHOs), as well as ammoniaoxidising organisms (ANOs) and their interaction with organic compounds, nitrogen and phosphorus. After preliminary verifications, it was found that the deterministic model accurately represented the kinetics involved with the ammonia and nitrate/nitrite concentrations. However, it was also established that the major limitations of the deterministic model are its exclusion of phosphate precipitation and its failure to incorporate the production of particulate and soluble organics due to the respiration, excretion and mortality processes.
Review: Continuous simulation modelling for design flood estimation – a South African perspective and recommendations
Authors: Rowe TJ , Smithers JC
Published: November 2018

A number of severe flooding events have occurred both in South Africa and internationally in recent years. Furthermore, changes in both the intensity and frequency of extreme rainfall events have been documented, both locally and internationally, associated with climate change. The recent loss of life, destruction of infrastructure, and associated economic losses caused by flooding, compounded by the probability of increased rainfall variability in the future, highlight that design flood estimation (DFE) techniques within South Africa are outdated and in need of revision. A National Flood Studies Programme (NFSP) has recently been initiated to overhaul DFE procedures in South Africa. One of the recommendations in the NFSP is the further development of a continuous simulation modelling (CSM) system for DFE in South Africa. The focus of this paper is a review of CSM techniques for DFE, to guide further development for application in South Africa. An introduction to DFE, and particularly the CSM approach, is presented, followed by a brief overview of DFE techniques used in South Africa, leading into a more detailed summary of CSM for DFE within South Africa to date. This is followed by a review of the development and application of CSM methods for DFE internationally, with a focus on the United Kingdom and Australia, where methods have been developed with the intention of national scale implementation. It is important to highlight that there is a plethora of CSM methods available internationally and this review is not exhaustive; it focuses on and identifies some of the strengths and weaknesses of several popular methods, particularly those intended for national scale application, as the intended outcome from this review is to identify a path towards the development of a usable national scale CSM system for DFE in South Africa. Emphasis on a usable method is important, considering the reality that, despite promising results, numerous benefits, and national scale methods being developed, it appears that the CSM method for DFE is rarely used in practice.
Development of Consumer Perception Index for assessing greywater reuse potential in arid environments
Authors: Shafiquzzaman Md , Haider Husnain , AlSaleem Saleem Saleh , Ghumman Abdul Razzaq , Sadiq Rehan
Published: November 2018

Arab countries are primarily situated in arid environments and face serious water scarcity challenges due to growing populations, urbanization, and climate change impacts. Reusing greywater, if adequately treated at the point of generation, poses less human health risk as compared to blackwater reuse. Consumers have several reasons for being unwilling to reuse greywater, including potential health risk, religious and cultural concerns, and feeling uncomfortable. There are several possible reuse applications of treated greywater, such as watering plants, floor cleaning, landscaping, toilet flushing, etc. Therefore, it is important to assess consumer perceptions about greywater reuse before its implementation in any region. In this research, a framework based on greywater reuse indicators (GWRI) was developed to assess consumer perceptions before and after introducing low-cost treatment (LCT). Later the framework was implemented for Muscat, Oman. A questionnaire survey was carried out with 110 households located in diverse socioeconomic settings to collect data about general demographics, existing water uses, water sources, greywater applications (after LCT), and in-house plumbing systems. Seven key GWRI were estimated and aggregated to develop an overall consumer perception index (CPI). The study results revealed that CPI improved significantly from ‘very low’ to ‘high’ after introducing LCT. However, governments should provide financial assistance to consumers for improving in-house plumbing systems, based on detailed investigations. The studyrevealed that the CPI can be applied across the globe and can save time and effort for municipal managers, engineers, and policy makers by providing information that will enable effective decision-making.

La Wiki-Webquest: Una Actividad Colaborativa En La Asignatura De “Nuevas Tecnologías Aplicadas A La Educación”
Authors: Santos Fernández Roberto , Carramolino Arranz Beatriz , Rodríguez Navarro Henar , Rubia Avi Bartolomé
Published: November 2018

Las instituciones de educación superior están sufriendo un proceso de reconversión buscando su adaptación a las características del Espacio Europeo de Educación Superior. Uno de los cambios más importantes, a los que debe hacer frente su profesorado, consiste en una reorganización metodológica diferente de sus clases. Por ello, es necesario pensar en nuevas fórmulas en la formación del profesorado.

Como resultado de esta necesidad, decidimos organizar la asignatura de Nuevas Tecnologías Aplicadas a la Educación, de la Facultad de Educación de Valladolid, empleando una metodología activa, el IBL, apoyada en una plataforma Wiki, proponiendo a nuestro alumnado una serie de actividades que debían realizar colaborativamente.

En este trabajo, presentamos una de esas actividades, la elaboración de una Wiki-WebQuest. A partir de la descripción de esta actividad, pretendemos mostrar algunas luces y sombras sobre su puesta en práctica (la versatilidad y flexibilidad de la plataforma, la posibilidad de colaboración entre la universidad y la escuela, la falta de adaptación de algunos contenidos al nivel curricular del curso concreto, la falta de asesoramiento del profesorado al alumnado de primaria sobre el uso de estas nuevas herramientas, etc.)

Esta actividad fue desarrollada a partir de la colaboración con contextos educativos reales (dos centros de primaria), sirviendo de caso de estudio para diseñar una Wiki-WebQuest. Asimismo, también colaboraron dos asignaturas de la titulación de Magisterio (Didáctica General y Metodología del Idioma Extranjero), con el objetivo de enriquecer el proceso de aprendizaje.
Arquitectura en territorios informados y transparentes. Una wiki en la escuela de arquitectura
Authors: Fernández García Javier
Published: November 2018

El marco general de nuestra investigación en la universidad son los espacios de convivencia, información y formación que configuran  los  habitantes en un territorio online. La Web 2.0 nos ha dotado de nuevas herramientas con la que construir espacios. Desde la fundación en agosto de 2006 de CityWiki, indagamos en la arquitectura de estos lugares que se articulan en un espacio común en el que, a falta de jerarquía y policía, la acción en él la define el  empoderamiento y la libertad del ciudadano responsable. A modo de laboratorio, desde entonces, embarcamos la actividad investigadora y docente en la actitud 2.0 incluida en la WWW.

En la primera parte de este artículo se expone el pensamiento actualizado que empíricamente evoluciona emparejado a la actualidad de nuestras investigaciones. El objetivo es hacer entender el territorio wiki como informado y transparente llamado a añadir capas de información a la realidad para de esta forma no sustituirla sino ampliarla.  Seguidamente, en la segunda parte, se describe y analiza la experiencia de innovación llevada a cabo durante el curso 2007/2008 en la que se ensayó un modelo docente instrumentados en los modos y paisajes previamente descritos.
O desenvolvimento e a aprendizagem da criança na concepção de Vigotski: uma relação dialética
Authors: Souza Leandro Aparecido de
Published: November 2018

O presente trabalho constitui-se num ensaio teórico que tem como objetivo, além de refletir acerca de alguns elementos do processo de aprendizagem e desenvolvimento da criança à luz da teoria de Vigotski, propor uma atividade prática, em sala de aula, demonstrando como eles podem se materializar a partir da teoria histórico-cultural. Muitas pesquisas que investigam essa temática concentram-se no processo de aprendizagem da criança no âmbito da escola, buscando fundamentos que legitimem as práticas escolares e as atividades a ela relacionadas. A apropriação desses conhecimentos é de fundamental importância, especialmente aos professores alfabetizadores, que vivenciam cotidianamente questões relacionadas à aprendizagem do aluno associada ao desenvolvimento psíquico da criança. A metodologia utilizada pauta-se em uma abordagem qualitativa contemplando a descrição, análise e reflexão dos elementos apresentados. A reflexão oportunizada no artigo permite concluir que a teoria histórico-cultural, por basear-se em uma lógica dialética, e por considerar a importância das relações sociais para a aprendizagem e o desenvolvimento do homem, fornece fundamentos que podem contribuir para o aprimoramento das relações que se estabelecem nos espaços escolares, principalmente para a reflexão sobre as práticas docentes em sala de aula.
A linguagem poética na comunidade virtual: uma outra voz como alternativa para a linguagem e o pensar técnicos
Authors: Fanini Angela Maria Rubel
Published: November 2018

Neste artigo, trazemos alguns discursos já canônicos sobre as relações entre tecnologia e sociedade (Heidegger, Marcuse, Leroi-Gourhan, MacLuhan, Habermas, Jonas e Feenberg), apresentando as visões determinista, funcional, neutra, substancialista e histórico-crítica da técnica. Focamos a atenção mais pormenorizadamente nas ideias de Heidegger e Feenberg para propor a inserção da linguagem poética, meditativa e reflexiva na ágora virtual, a fim de reforçar um pensar menos técnico, imediatista, superficial e pouco engajado que impera nas redes sociais. Apostamos na figura dos educadores para incentivar uma discussão e uma problematização sobre tecnologia, linguagem e sociedade, com o objetivo de criar e expandir uma comunidade virtual mais democrática e plural, em que múltiplas vozes possam emergir.
Valores-notícia no romance-reportagem Aracelli, meu amor, de José Louzeiro
Authors: Junior José Ferreira
Published: November 2018

O trabalho aborda os critérios de noticiabilidade dentro do gênero romance-reportagem – híbrido entre o discurso jornalístico e o discurso literário –, produzido na década de 1970, época em que se vivia sob um regime militar no Brasil. Analisam-se, dessa forma, os valoresnotícia que norteiam a seleção de informação e produção do texto final de Aracelli, meu amor – Um anjo espera a justiça dos homens (1976), do jornalista e escritor maranhense José Louzeiro. Busca-se compreender como esses critérios eram utilizados, observando o contexto de censura à liberdade de expressão em que a obra foi elaborada, decorrente do Ato Institucional Número 5 (AI-5). Abordam-se também as nuances de denúncia social da obra em estudo, tendo em vista que o gênero romance-reportagem assume configurações de uma literatura de resistência, levando o público a reflexões sobre as convulsões sociais da época. Para a análise, tomam-se como parâmetros, primordialmente, os conceitos de valor-notícia e de critérios de noticiabilidade estabelecidos por Traquina (2008), Galtung e Ruge (1965) e Ericson, Baranek e Chan (1987). Esses autores colaboram, ainda, para a análise das teorias convergentes do jornalismo e da literatura, nas quais se encontram os fundamentos iniciais para pensar a natureza social do jornalismo. Identificaram-se, na obra corpus, muitos critérios sistematizados pelos teóricos referenciados, entre eles, os valores-notícia como a morte, a notoriedade, a proximidade, a relevância, o tempo, a notabilidade, o inesperado, a infração, a personalização, a negatividade, a amplitude e a dramatização. Entende-se, portanto, que esses critérios são fundamentais para conferir importância jornalística à narrativa de José Louzeiro.
A visibilidade da pesquisa hoje em universidades espanholas
Authors: Rivas Noa María Carballa
Published: November 2018

Las universidades son unas instituciones en las que el capital humano es el principal valor. Son los profesionales, especialmente el PDI, los que aportan las dos principales tareas de cara a la sociedad: la docencia y la investigación. Cómo realicen el trabajo encomendado será la clave para la reputación de la propia institución. A su vez las universidades, a través de sus gabinetes de comunicación, deben promover la difusión de las actividades del capital humano para una mejor reputación. En el presente estudio se analizará qué plan de promoción realizan diversas universidades españolas sobre su docencia e investigación, de tal manera que esta pudiera repercutir a la larga sobre la reputación del centro.
A retextualização da oralidade no telejornal bom dia São Paulo
Authors: Garcia Edson Roberto Bogas , Silva Luis Roberto da
Published: November 2018

Por meio da linguagem, podemos perceber o mundo em que vivemos, produzindo relaçõesque nos permitem situar como indivíduos que pertencem a uma determinada comunidade. Procurar entender suas variações, potencialidades e suas finalidades, enfim, torna-nos capazes de compreender diferentes situações, diferentes olhares, diferentes maneiras, de, por exemplo, noticiar um acontecimento, narrar um episódio e manifestar ideologias. A partir dessa proposição, a presente pesquisa tem como objetivo analisar o uso da oralidade nas apresentações das reportagens do telejornal matinal “Bom Dia São Paulo” da Rede Globo. Para tanto, utilizamos o arcabouço teórico de retextualização, proposto por Marcuschi (2004). De acordo com o autor, são nove operações realizadas para a transcrição de um texto oral para o escrito. O corpus escolhido foi ‘as cabeças das matérias’ dos apresentadores, Rodrigo Bocardi e Glória Vanique, de duas edições, exibidas em uma sexta-feira. O primeiro jornal foi apresentado no dia 27 de fevereiro de 2015 e o segundo, um mês depois, 27 de março de 2015. Notamos que, em grande parte das análises, foi possível a retextualização, motivo pelo qual comprovamos nossa tese inicial sobre o uso da linguagem oral no telejornal pesquisado.
A companhia de Jesus e sua relação com os enclaves da expansão portuguesa
Authors: Menezes Sezinando , Costa Célio , Borges Felipe Augusto Fernandes , Silva Saulo Henrique Justiniano
Published: November 2018

O trabalho ora apresentado analisa a expansão marítima comercial portuguesa, iniciada no século XV e consolidada no XVI, destacando a participação ativa da Igreja nesse processo. A partir de concessões às Coroas Ibéricas, especialmente a Portugal, a Igreja institui o que chamamos de Padroado Real Português, instituição que dava ao soberano luso poder e autoridade sobre as missões do Ultramar, ao passo que lhe impunha também obrigações a serem cumpridas. Não obstante, abordamos ainda a criação da Companhia de Jesus, bem como sua consolidação e estreita relação com a Coroa Portuguesa nas missões do Padroado. Mostramos como a partir de suas primeiras relações com a Coroa Portuguesa, os jesuítas adquirem um lugar privilegiado em relação às outras ordens.
O que nos fala o cinema sobre a juventude? O regime de facções em insurgente e a fixidez identitária
Authors: Gomes Greice Rosane , Farina Cynthia
Published: November 2018

Este artigo investiga os processos de subjetivação na atualidade e as relações entre cinema e juventude, a partir da análise do filme Insurgente (SCHWENTKE, 2015). O trabalho é um desdobramento da pesquisa que desenvolvo sobre cinema e público jovem, na qual estudo as maneiras pelas quais a produção cinematográfica e a juventude interferem-se mutuamente. Entre as motivações deste trabalho está a de investigar de que forma o cinema, precisamente este blockbuster, tematiza as características e os principais conflitos da juventude na contemporaneidade e quais mecanismos atuam para o jovem espectador enxergar-se nessa trama. Para isso, trago uma breve justificativa do porquê pesquisar o cinema no âmbito da educação, recupero algumas características da produção cinematográfica atual e situo o leitor em relação à definição de juventude utilizada no trabalho. O referencial teórico é norteado

prioritariamente por Deleuze, Guattari, Foucault e Rolnik, e a metodologia utilizada é a cartografia. A partir da temática e de elementos trazidos pelo filme, algumas problematizações são colocadas, como a associação do regime de facções apresentado na trama com a fixidez identitária dos kits de perfis-padrão (ROLNIK, 1997) oferecidos aos jovens na atualidade. Ao abordar essa serialização que se dá sobre o indivíduo, revelando um mecanismo muito mais amplo e que está para além dele, lanço mão do conceito de agenciamento coletivo de enunciação (GUATTARI, 1996). Em seguida, relaciono a existência dos divergentes à possibilidade de singularização (GUATTARI, 1996), problematizando a reterritorialização, extensiva ao espectador por meio da empatia (BOAL, 2013), pela qual passa a personagem principal do filme. A análise do filme à luz dos autores utilizados indicou uma tendência da película em reafirmar, frente a seu público, a aceitação passiva do regime de facções trazido pelo longa e, por conseguinte, do próprio quadro de referências identitárias oferecido ao jovem em nossa cultura.
Representações da loucura feminina no cinema – Augustine e nimphomaniac
Authors: Santos Maria Inês Detsi de Andrade , Pinheiro Clara Virgínia de Queiroz
Published: November 2018

Neste artigo, analisamos representações sobre a loucura feminina em duas produções cinematográficas: Augustine e Nimphomaniac, tendo como referências discursos que orientam a construção das representações sobre a loucura e o tratamento dado às mulheres a quem se atribui essa condição. Com esse estudo, reafirmamos o caráter histórico e social da loucura, considerando que a exclusão do louco está relacionada aos processos sociais de exploração e dominação; e com suas hierarquias (de classe, gênero, etnia). Nesses processos, os diversos discursos podem adquirir um caráter ideológico e desempenhar uma função justificadora da ordem social.
