Contrôle des concentrations d'aluminium et de silice dissous lors de l'interaction des eaux et des roches magmatiques
Authors: Michard Gil , Sarazin Gérard , Iundt François
Published: November 2018

Different quantitative models used to represent weathering of magmatic rocks lead to a set of mathematical relations between several parameters actually measurable in natural water samples. Results concerning regional studies (Margeride granite and basalts and andesites from Cantal) show that among the three models tested, only one may explain experimental data. The model assumes partial equilibrium between solution and secondary minerals. These are very poorly crystallized and their size may be estimated to 50 Å.

Dissolution d'une solution solide : étude théorique et expérimentale
Authors: Denis Jérôme , Michard Gil
Published: November 2018

From a discussion of the equilibrium conditions of a water-solid solution system and the notion of congruent dissolution, we propose two different ways of reaching stable equilibrium.

We first assume congruent dissolution of the initial solid :

A B1-x Cx → A- + (l-x) B+ + xC+

and the reprecipitation of a new solid phase following the partition relation between water and precipitate :

|AC|/|AB| = D|C+|/|B+|

where |AC| and |AB| are the concentration of the two end members in the precipitate, |C+| and |B+| ion activities in solution and D the partition coefficient.

The first model is based on instantaneous equilibrium between water and precipitate, the second is a kinetic approach. Both tend towards thermodynamic equilibrium between water and the solid-solution. We have applied these models to experimental results obtained in the laboratory.
Formes et micro-reliefs de lapiés. Approche morphométrique et morphogénique. Application au massif de Totes-Gebirge (Autriche)
Authors: Veress Márton , Tóth Gábor
Published: November 2018

L'étude sur les surfaces lapiazées proposée dans cet article a été réalisée dans le massif de Tote-Gebirge en Autriche. Il s'agit d'appréhender l'agencement de microformes qu'on rencontre fréquemment dans les lapiés, notamment le développement "de buttes de lapiés" et de "hums de lapiés". Une classification de ces microformes est ici proposée. Ces microformes se développent souvent à l'extrémité des rigoles, à la convergence des rigoles ou encore par un phénomène de capture régressive. Après étude de ces microformes de lapiés, sont présentées les différentes méthodes mises en place pour étudier en détail les lapiés. Ces méthodes de relevé nous ont permis de mieux saisir le développement des "buttes de lapiés" et des "hums de lapiés" ainsi que leur évolution. L'étude morphogénique de ces microformes permet alors de connaître l'âge approximatif du développement des surfaces lapiazées. Les cartes présentées prennent en considération l'âge relatif du développement de ces formes karstiques et l'environnement des microformes ici étudiées.

Hydrocompaction, solution, suffosion and piping as processes of forming depression contours.

The authors of this note provide a definition for four processes (hydrocompaction, solution, suffosion, piping) which, although different, are likely to result in comparable surface morphologies, such as closed hollows. They attempt to clarify the specific features of each of these processes.
Association Analysis of Three Diverse Rice (Oryza sativa L.) Germplasm Collections for Loci Regulating Grain Quality Traits
Authors: Huggins Trevis D. , Chen Ming‐Hsuan , Fjellstrom Robert G. , Jackson Aaron K. , McClung Anna M. , Edwards Jeremy D.
Published: November 2018

Rice (Oryza sativa L.) end‐use cooking quality is vital for producers and billions of consumers worldwide. Grain quality is a complex trait with interacting genetic and environmental factors. Deciphering the complex genetic architecture associated with grain quality provides essential information for improved breeding strategies to enhance desirable traits that are stable across variable climatic and environmental conditions. In this study, genome‐wide association (GWA) analysis of three rice diversity panels, the USDA rice core subset (1364 accessions), the minicore (MC) (173 accessions after removing non‐sativa), and the high density rice array–MC (HDMC) (383 accessions), with simple sequence repeats, single nucleotide polymorphic markers, or both, revealed large‐ and small‐effect loci associated with known genes and previously uncharacterized genomic regions. Clustering of the significant regions in the GWA results suggests that multiple grain quality traits are inherited together. The 11 novel candidate loci for grain quality traits and the seven candidates for grain chalk identified are involved in the starch biosynthesis pathway. This study highlights the intricate pleiotropic relationships that exist in complex genotype–phenotypic associations and gives a greater insight into effective breeding strategies for grain quality improvement.
A METHOD FOR ANALYZING THE EFFECT OF IMPLEMENTING AN ENTERPRISE SYSTEM BASED ON THE COMPLEXITY OF ACTIVITIES
Authors: Lee Chijoo , Lee Chiheyon , Lee Eul-Bum
Published: November 2018

This paper presents a method for analyzing the effect of implementing an enterprise system (ES) in the construction industry during the ES introduction and planning stages. The effect is a reduction in employees’ work time. The proposed method is based on the 1) level of digitalized and automated activities, the 2) complexity of the activities, and the 3) complexity of the processes in the workflow. The method was applied at a construction company that has no enterprise resource planning (ERP), and the method’s accuracy was evaluated by information technology consultants who have performed planning, construction, and operation in relation to ERP. The result shows that the effect of management business was the largest; most of this effect was on data management and review. After users became familiar with ERP, the reduction in data input time increased. The analysis method takes less time and costs less than using surveys to measure the work time and satisfaction of ES users. It can also identify processes in which the effect increases or decreases, thereby guiding any modifications of the ES before it is introduced.
Flow-line Wandering in the Turbulent Solar Wind and Space Environment Forecasts
Authors: Ragot B. R.
Published: November 2018

Space environment forecasts are based on ab initio modeling of the solar wind (SW) wherein solar magnetic fields and plasmas are propagated from an initial/boundary model source surface in the lower solar corona out to 1 au. Testing of these space environment forecasts relative to in situ measurements at 1 au typically shows uncertainties in the arrival times of fast SW streams of the order of a day, with broad distributions, means/medians of the order of half a day, and large variations between models but no definite winner. Here the effect of flow-line (FL) wandering due to the higher frequency velocity fluctuations within the turbulent SW on the arrival-time statistics of parcels of SW plasma transiting through the inner heliosphere out to 1 au is evaluated for a range of cutoff timescales in the velocity fluctuations. Used for this evaluation are in situ SW velocity measurements onboard Wind at 1 au, detailed spectral analysis of these measurements, WKB extrapolations to the inner heliosphere and simple application of a newly extended theoretical calculation of the mean SWFL cross-flow and “flow-aligned” displacements from the measured spectra. It is found that the velocity fluctuations near 1 au have little effect on the arrival times. The effect of the velocity fluctuations increases sunward, however, to a level sufficient to explain the large and broadly distributed “uncertainties” found in the testing of the forecasts.

Archaeological sites can be discovered and recorded in a high-resolution and non-invasive manner using geophysical methods. These measure the spatial variation of a range of physical properties of the soil which may be representative proxies of the subsurface archaeology. Less-invasive and cost-effective field procedures have become top-priority to mitigate the destructive effects on our cultural heritage from intensified land use, climate change and the current conflict panorama.

At a time when many organisations are investing in advanced geophysical equipment, a major problem is that our ability to fully interpret the information available from geophysical datasets is still very limited. This deficiency prevents geophysical survey moving beyond basic prospection and becoming a significant tool for answering nuanced questions about archaeology and their host landscapes. This limitation arises from an incomplete understanding of the relationship between soil properties and geophysical measurements. Bridging this gap requires multi-disciplinary teams, testing novel methods, plus scholarly discussion to collate the outcomes of projects on this topic. Overcoming these challenges is a prerequisite for maximising the costeffectiveness of geophysical methods, realising the expected benefits of technological investment and allowing broader utility of geophysical methods in the cultural heritage sector.

SAGA will build an international network of geophysicists, archaeologists, soil scientists and other experts to develop our capability to interpret geophysical data and promote research collaborations. Our vision is that after four years, SAGA will have created an environment within which emerging field procedures, enhanced data interpretation and a broader understanding of integrated geophysical methods can flourish.

Published: November 2018

Claviplatysgen. n. and its type species C.henryisp. n. (Hemiptera: Heteroptera: Plataspidae: Plataspinae) are described from Kerala, India. The new genus is related to the Indomalayan genera Heterocrates Amyot & Serville, 1843, Cratoplatys Montandon, 1894, and Cronion Bergroth, 1891, but differs from them and all other plataspid genera by the peculiarly modified antenna. The morphological characters and systematic relationships of the above genera are discussed.

Authors: Curtis Jeffrey R. , Xie Fenglong , Yang Shuo , Danila Maria I. , Owensby Justin K. , Chen Lang
Published: November 2018

Objective.

The clinical utility of the multibiomarker disease activity (MBDA) test for rheumatoid arthritis (RA) management in routine care in the United States has not been thoroughly studied.

Methods.

Using 2011–2015 Medicare data, we linked each patient with RA to their MBDA test result. Initiation of a biologic or Janus kinase (JAK) inhibitor in the 6 months following MBDA testing was described. Multivariable adjustment evaluated the likelihood of adding or switching biologic/JAK inhibitor, controlling for potential confounders. For patients with high MBDA scores who added a new RA therapy and were subsequently retested, lack of improvement in the MBDA score was evaluated as a predictor of future RA medication failure, defined by the necessity to change RA medications again.

Results.

Among 60,596 RA patients with MBDA testing, the proportion adding or switching biologics/JAK inhibitor among those not already taking a biologic/JAK inhibitor was 9.0% (low MBDA), 11.8% (moderate MBDA), and 19.7% (high MBDA, p < 0.0001). Similarly, among those already taking biologics/JAK inhibitor, the proportions were 5.2%, 8.3%, and 13.5% (p < 0.0001). After multivariable adjustment, referent to those with low disease MBDA scores, the likelihood of switching was 1.51-fold greater (95% CI 1.35–1.69) for patients with moderate MBDA scores, and 2.62 (2.26–3.05) for patients with high MBDA scores. Among those with high MBDA scores who subsequently added a biologic/JAK inhibitor and were retested, lack of improvement in the MBDA score category was associated with likelihood of future RA treatment failure (OR 1.61, 95% CI 1.27–2.03).

Conclusion.

The MBDA score was associated with both biologic and JAK inhibitor medication addition/switching and subsequent treatment outcomes.
On the Analytic Solution of Magnetohydrodynamic (MHD) Flow by a Moving Wedge in Porous Medium
Authors: Berrehal Hamza , Maougal Abdelaziz , Hayat Tasawar , Alsaedi Ahmed
Published: November 2018

This paper is devoted to find analytic approximate solution by optimal homotopy asymptotic method (OHAM) for the problem of nonlinear boundary layer flow. Two-dimensional magneto-hydrodynamic (MHD) flow of a viscous fluid over a moving wedge in porous medium with suction/injection is investigated. Governing equations are transformed by similarity method into a third order Falkner-Skan equation and solved analytically using OHAM. This approach is highly efficient, ensuring a very rapid convergence of the solution only after one iteration. Graphical results are presented to discuss the effects of various parameters on velocity profiles. Further, the skin friction coefficient is also tabulated and compared with the corresponding results available in literature. Our results were found in an excellent agreement.
Radiation Effect on the Entropy Generation of Carbon Nanotubes Water-Based Nanofluid Flow by a Moving Wedge
Authors: Berrehal Hamza , Maougal Abdelaziz , Hayat Tasawar
Published: November 2018

This paper deals with the effect of thermal radiation on the entropy generation of carbon nanotubes water-based nanofluid flow past a moving wedge. Two different types of nanoparticles, namely single wall carbon nanotube (SWCNT) and multi wall carbon nanotube (MWCNT) are considered. Governing equations of the problem are transformed by similarity method into a set of nonlinear ordinary differential equations (ODEs) and solved analytically using optimal homotopy asymptotic method (OHAM). Expression of entropy generation number is obtained in dimensionless form. Further the analytical results of temperature, Nusselt number, skin friction, entropy generation number and Bejan number are discussed and analyzed through graphs. These results show that the entropy generation number has a minimal value for larger radiation parameter and the negative values of velocity ratio parameter λ, while nanoparticles have influence to increase the entropy production.

Published: November 2018

The Double Crystal Monochromator (DCM) will be developed at the Brazilian Synchrotron Light Laboratory (LNLS) to select the desired X-Ray wavelength of Sirius, the new Brazilian fourth generation synchrotron. Components of this optical instrumentation can be obtained through welding processes, such as brazing, soldering, and diffusion bonding. The use of vacuum welding technique ensures union of silicon with FeNi alloy, Invar36 (64Fe-36Ni) from Grupo Metal and Invar39 (61Fe-39Fe) from Scientific Alloys. Union of these materials was performed with filler alloys from Nihon Superior, such as ALCONANO (nanosilver paste), SnSb (95Sn-5Sb), Sn100C (Sn-0.7Cu-0.05Ni-0.01Ge), and Sn100CV (Sn-5Bi-0.8Cu-0.05Ni). Following welding tests, microstructural and metallographic analysis of the interface region between the materials involved are performed to investigate the junction among silicon, filler alloy, and base metal. Microstructural characterization carried out by a QUANTA SEM (Scanning Electron Microscope) with EDS (Energy Dispersive Spectroscopy) technique to identify the composition, distribution, and morphology of the phases. Based on these analyses, the best parameters were Invar39/Sn100CV/Si samples using base materials coated with different depositions: one gold and the other copper. In the mechanical test, the specimen with copper film presented higher shear strength.
Influence of Non-Uniform Heat Source/Sink on Unsteady Chemically Reacting Nanofluid Flow over a Cone and Plate
Authors: Basha H. Thameem , Sivaraj R. , Animasaun I.L. , Makinde Oluwole Daniel
Published: November 2018

This computational study explores the properties of non-uniform heat source/sink on the fluid transport properties of a chemically reacting nanofluid with two types of geometries saturated with porous medium. Simulations have been done to investigate the heat and mass transfer characteristics using Crank-Nicolson scheme. Influence of active parameters such as Hartman number, heat source and sinks, Brownian diffusion, higher order chemical reaction, Prandtl number and thermophoretic diffusivity are graphically presented. Tables demonstrate the significant impact of sundry parameters on skin-friction factor, heat and mass transfer rates. The achieved results expose that the heat source/sink parameter has high influences on the fluid flow and heat transfer characteristics. A decrease in average skin friction factor due to the magnetic field is more significant in the flow on a plate than that of cone.

Published: November 2018

The study on liver cancer has been performed in clinical medicine and medical science for a long time. Within the few recent years, there are many new emerging biomedical technologies that help better assess on the liver cancer. Of several new technologies, the advanced cell technologies for the assessment of liver cancer, organoids technology is very interesting. In fact, the organoids is an advanced cell research technique that can be useful for studying of many medical disorders. Organoids can be applied for study on the pathophysiology of many cancers. The application for studying on liver cancer is very interesting issue in hepatology. In this short article, the author summarizes and discusses on applied organoids technology for studying on various kinds of liver cancers. The application can be seen on primary hepatocellular carcinoma, metastatic cancer, cholangiocarcinoma, hepatoblastoma, as well as other rare liver cancers.
An Unusual Presentation of Prostate Carcinoma
Authors: Sadasivan Greeshma , Arul R , Prabaharan A
Published: November 2018

Prostate carcinoma is the second most common cancer among men worldwide. Although prostate carcinoma is common, its presentation resembling retroperitoneal fibrosis is uncommon. We report a patient with prostate carcinoma mimicking retroperitoneal fibrosis. An elderly male presenting in a volume overload state with features of obstructive uropathy was diagnosed as a case of prostate carcinoma. Magnetic resonance imaging was suggestive of retroperitoneal fibrosis. The presentation of prostate carcinoma as retroperitoneal fibrosis is rare.

Authors: Kose Dogan , Ozdemir Hulya , Celik Zeliha Esin , Unlu Ali , Artac Hasibe , Koksal Yavuz
Published: November 2018

Aim: This study was planned to research the relationship between doxorubicin cardiomyopathy and the soluble Fas (sFas) level. Materials and Methods: Two groups of rats were included in the study. The control group was given physiological saline, while the study group was given doxorubicin. The rats, whose blood samples were taken weekly, were sacrificed and their myocardial tissues were removed. The tissues were examined in terms of morphological changes and surface Fas expression, while the blood samples were examined in terms of sFas level. Results: In the study group, the sFas levels at 2nd–9th weeks were higher than those found at 1st week before administrating the drug, and the increase at 2nd–7th weeks was meaningful. In addition, sFas levels were gradually increased each week during 1st–5th weeks when compared to the values of a previous week, and the increase during the first 4 weeks was meaningful. After the 5th week, the values gradually decreased each week. The mean values of the study group at 1st–8th weeks were higher than those of the control group, and the increases at 2nd–8th weeks were meaningful. The severe forms of interfibrillar hemorrhage, vascular dilatation, myocardial necrosis, inflammatory infiltration, and splitting of muscle fibers occurred with 15, 15, 17.5, 20, and 22.5 mg/kg dose of medicine, respectively. Conclusions: As the tissue injury increased, the increasing cell-surface Fas expression and sFas plasma level at the acute phase of doxorubicin-related cardiotoxicity decreased. The sFas level determined at acute phase may be helpful in predicting the existing injuries and possible late-term problems.
Waardenburg Syndrome and Left Persistent Superior Vena Cava
Authors: Raissi Driss , Christie Alexander , Applegate Kimberly
Published: November 2018

Waardenburg syndrome (WS) is a rare genetic disorder secondary to neural crest cell developmental abnormalities. It is predominantly described as an auditory–pigmentary syndrome with diverse patient presentation, typically involving congenital sensorineural hearing loss and pigmentation abnormalities of the skin, hair, and iris. Other developmental abnormalities that may be associated with this syndrome are Hirschsprung's disease and a myriad of cardiovascular congenital defects. We present a case of a young girl with WS who found to have a persistent left superior vena cava (PLSVC) draining into the coronary sinus. The prevalence of PLSVC is increased in patients with chromosomal and genetic abnormalities. However, we are the first to report its presence in association with WS while discussing the challenges that may arise during central venous catheter placement in patients with PLSVC.
Estructuras y significados de trayectorias manageriales en grandes empresas argentinas

Published: November 2018

Este artículo indaga cómo quienes aspiran a ocupar puestos directivos en grandes empresas argentinas perciben y significan la competencia de la carrera managerial. Se busca explorar la relación compleja entre el modo en que las organizaciones son diagnosticadas y pensadas en términos objetivos, y cómo son diagnosticadas y pensadas en términos subjetivos, es decir, el modo de vivirlas y de percibir la propia experiencia laboral en diseños organizacionales específicos. Se realizó una investigación cualitativa en ocho grandes empresas de Argentina de diversos sectores y formas de propiedad donde se entrevistó a 88 managers  y se realizaron 12 entrevistas en profundidad a los directores y responsables de recursos humanos así como a informantes clave. Identificamos que  la competencia hacia la cima se significa como up or out, constricción elusiva y dinámica tradicional, y que la dinámica temporal de la carrera se significa en términos de estancamiento, turning points o status passages. La inclusión de estos significados y apreciaciones subjetivas, junto con los elementos objetivos que derivan del diseño de la organización, son fundamentales para un análisis de las organizaciones como fenómenos complejos.
The case for microsimulation frameworks for integrated urban models
Authors: Miller Eric J.
Published: November 2018

The primary objective of this paper is to “make the case” for adoption of microsimulation frameworks for development of integrated urban models. Similar to the case of activity-based travel models, microsimulation in integrated urban models enables such models to deal better with: heterogeneity and non-linearity in behavior; identification of the detailed spatial and socioeconomic distribution of impacts, benefits and costs; tracing complex interactions across agents and over time; providing support for modelling memory, learning and adaptation among agents; computational efficiency; and emergent behavior. The paper discusses strengths, weaknesses and challenges in microsimulating urban regions, including the extent to which microsimulation models are still subject to Lee’s famous “seven sins of large-scale modelling,” as well as the extent to which they may help alleviate or reduce these sins in operational models. The paper concludes with a very brief discussion of future prospects for such models.
Towards a Pragma-Semiotics of Ritual(ized) Gesture and Performance
Authors: Blanariu Nicoleta Popa
Published: November 2018

This paper analyzes some ritual and performing phenomena from different cultures, by using a unifying pragma-semiotics approach, especially the speech acts theory. Claude Lévi-Strauss (1995) refers to the rites as a “paralanguage”. In our opinion, his taxonomy of ritual praxis is reducible to the dichotomy constative/performative introduced by John L. Austin (1962), that he later reconsiders and transforms into the trichotomy locutionary / illocutionary / perlocutionary. In Austin’s opinion, the speech acts theory is part of a theory of action. We aim to explain that this is confirmed not only in the very linguistic act of utterance, but also in the multimodal expression (movement, gesture, word, incantation, costumes, accessories) specific to some ritual(ized) social contexts, particularly ritual performances. Like verbal performative utterances, ritual(ized) gesture and movement may have real and immediate efficiency, which means that it may produce a real-world change, from the participant’s viewpoint. Without a ritual context, the choreo-dramatic expression loses its pragmatic function – that of “modification” of the real (Lévi-Strauss, 1995). However, it manifests a different one, essentially “aesthetic”. From our point of view, the illocutionary ritual act is thus replaced by a “fictional act”, a category which was previously described by both John R. Searle (1982) and Gérard Genette (1991).
Los "filmeurs" Joseph Morder y Alain Cavalier. Gesto fílmico de despojamiento y epistemología de la no manipulación
Authors: Monterrubio Lourdes
Published: November 2018

El presente artículo pretende analizar la práctica cinematográfica del filmeur a través de dos de sus máximos representantes en el espacio francés: Joseph Morder y Alan Cavalier. Se trata, por tanto, de determinar los planteamientos epistemológicos y las características estéticas de esta experiencia fílmica desarrollada en soledad, en la que la filmación se convierte en un “acto corporal y estético” caracterizado por la subjetividad, la intimidad, la inmediatez y la observación. El análisis de diferentes obras pertenecientes a ambos autores –Lettre de Joseph Morder à Alain Cavalier (2005), Joseph Morder par Alain Cavalier (2006), J’aimerais partager le printemps avec quelqu’un (2007), Le Filmeur (2005) y otras– permitirá evidenciar cómo estas experiencias de realidad van más allá de las prácticas diarísticas o autobiográficas, ya que la narración queda relegada en pos de la vivencia presente y espontánea del situarse “en el interior del acto de filmar”. Estas prácticas intimistas y minimalistas de un gesto cinematográfico de despojamiento están determinadas por la evolución de la tecnología utilizada y sus automatismos; en el caso de Morder desde el súper 8mm al teléfono móvil y en el de Cavalier a través de su pequeña cámara digital. Esta experiencia fílmica se define por una epistemología de la no manipulación que se convierte en transgresión de la ortodoxia cinematográfica.
Geometría y técnica en dos retablos-tabernáculos fingidos españoles: Ermitas de Nuestra Señora de La Soledad (Puebla de Montalbán, Toledo) y de San Isidro (Alcalá de Henares)
Authors: Maure-Rubio Miguel Á. , Plaza-Beltran Marta
Published: November 2018

Tratamos en este artículo de hacer un análisis geométrico descriptivo y gráfico, así como técnico, de dos obras maestras del retablo fingido español separadas por más de 140 años: el retablo de la ermita de Nuestra Señora de La Soledad de Puebla de Montalbán (Toledo), obra de los hermanos González Velázquez y fechado en 1741; y el retablo de la iglesia de San Isidro de Alcalá de Henares (Madrid), obra de Manuel Laredo y fechado en 1885. Ambas pinturas tienen en común representar un Tabernáculo, pero también tienen en común la grandiosidad y perfección en su trazado, además de estar realizadas por artistas poco afamados. El retablo-Tabernáculo es una arquitectura que se puede rodear y su representación sobre el muro conlleva un mayor conocimiento de las reglas de la perspectiva para su correcto trazado. Se analiza a su vez la influencia que tuvieron los quadraturistas y tratadistas de geometría en este tipo de representaciones. Junto a este análisis geométrico consideramos imprescindible adentrarnos en la materialidad de las obras, su estructura y estratificación que, unido al estudio de los métodos de trasposición de los bocetos y las técnicas pictóricas empleadas para las representaciones, nos ayudará a comprender mejor la metodología empleada por los autores en la confección de estas pinturas murales.
Sobre el mapa: estrategias de gestión de la información en la cartografía actual
Authors: Salgado de la Rosa M. Asunción , Raposo-Grau Javier F. , Butragueño-Díaz Belén
Published: November 2018

El mapa se ha transformado en el soporte ideal sobre el que gestionar múltiples las capas de información que afectan al territorio. Históricamente, las estrategias gráficas empleadas para la representación y comunicación de toda esa información, merece nuestra consideración en la medida en la que pueden extrapolarse estrategias proyectuales aplicables sobre el territorio. Tomando como punto de partida una serie de cartografías que, a lo largo de los años, han supuesto un avance en materia de comunicación gráfica, se hace un repaso de la contribución cultural que supone este soporte. Desde unos inicios que evidencian un tránsito desde el espacio topológico al de representación cartesiana, pasando por la búsqueda de herramientas de gestión gráfica de elementos cambiantes, así como la incorporación del Big Data en cartografías más próximas al diagrama que al mapa tradicional, podemos observar una necesaria confluencia de todos esos niveles de información. Todos estos recursos, sirven en la actualidad a los arquitectos y urbanistas, como punto de partida que permite no solo representar los aspectos más intangibles del proyecto, sino también explorar nuevas formas de comunicación multidimensional. En definitiva, nos otorga la capacidad de cartografiar no solo lo real, también lo imaginado.
Proyecto Retrato Social: lo que la educación formal puede aprender del arte comunitario
Authors: Macaya Albert , Valero Eloisa
Published: November 2018

El arte activista, caracterizado por la voluntad de incidir en su contexto social, tiene una de sus concreciones más interesantes en el llamado arte comunitario. El interés por lo comunitario es una preocupación compartida por diversos ámbitos del conocimiento, incluida la educación y las artes visuales. La redefinición del rol del artista como trabajador cultural en contextos sociales específicos se fundamenta en una idea horizontal y participativa de la creación artística. La traslación al ámbito de la educación formal de los principios y métodos del arte comunitario está dando lugar a interesantes experiencias en la línea de fomentar el pensamiento crítico y el compromiso cívico entre los jóvenes. La investigación que presentamos se basa en el estudio interpretativo de una experiencia de arte comunitario con estudiantes de bachillerato. En ella se confrontan evidencias textuales y visuales producidas en distintos momentos del proceso y compartidas por los participantes en formato de blog. Nos proponemos sospesar, a partir del caso de estudio, la eficacia de la propuesta como vía para potenciar la reflexión crítica, así como evaluar su desarrollo y alcance desde la perspectiva de los participantes.

Rivalizado con la ficción televisiva, el universo digital y las nuevas manifestaciones multimedia, el cine ha desplegado innumerables resortes para remozar su estética y adaptarla a los nuevos planteamientos y demandas del espectro cultural, entre los que encontramos los nuevos usos visuales, para los que es necesaria la corrección cromática. A lo largo de su trayectoria, el cine ha ido incorporando novedosos aspectos estéticos no solo para aumentar sus posibilidades técnicas, sino para constituir un paso al frente de la modernidad audiovisual. Pese a ello, tras la pátina de contemporaneidad y de renovación formal se alojan muchos de los planteamientos que se han ido desplegando a lo largo de la historia del cine, unos aspectos que entroncan con la tradición clásica y con la propia naturaleza cinematográfica. A lo largo de estas páginas evidenciaremos que el tratamiento del color en el cine actual realiza una constante revisión de los postulados cinematográficos tradicionales, así como descubriremos que la búsqueda del expresionismo psicológico y del naturalismo cromático son dos tendencias realmente distintivas de la era contemporánea. Ambos factores, favorecidos por la tecnología de la corrección cromática digital, supondrán una novedad en la visión estandarizada del tratamiento del color.

Waste is a discarded part generated from primary use of a material. In most cases, waste is very much unwanted and unusable but may be usable and beneficial for our economy and environment. Waste collectors are playing vital roles for the management of wastes though they are deprived of their basic needs. They are involved directly or indirectly to our economy and environmental development. However, whether waste collection activity has any effect on the socioeconomic status, hygiene practices, and microbial exposure of waste collectors remain unknown. Here we investigated socio-economic status, hygiene practices and microbial exposure of the waste collectors of Dhaka city in Bangladesh.

This study included two types of waste collectors in Dhaka city. One is the household waste collectors (HWCs) who belong to the formal waste management system of the city corporation and the other is the street waste collectors (SWCs) who belong to the informal waste management system that is executed mainly by the vulnerable groups of people locally called "Tokai". The total sample size was 150 (75 HWCs and 75 SWCs) who were randomly selected from 15 different sites (clusters) of the city. The research findings showed that 20% waste collectors were children and 76.67% were illiterate. The majority (72.7%) earned less than 150 BDT/day but the lion’s share was spent on food. The coverage of sanitary toilet facility was 42.0% whereas 70.7% SWCs had no toilet facility. The majority (82.7%) used to drink untreated water and 41.3% had disease episode in previous 30 days of data collection time. Only 28.0% waste collectors had bathing facility at home. Noticeably, no waste collector was wearing mask, gloves and apron while handling the waste. Analysis found that the status of HWCs was better than that of SWCs. Association among the variables showed that significant relationship existed between income level and percentage of expenditure on foods, types of drinking water and disease episode in previous 30 days, types of toilet used and hand washing practices. Microbiological analysis showed that the waste collectors were more exposed to the microbial hazards than the normal people.

HWCs and SWCs included in this study belong to vulnerable groups of Bangladesh. They are playing vital roles for cleaning and developing environmental conditions and living standards of Dhaka city though their contributions were mostly unrecognized. The present results suggested that socio-economic status, hygiene practices and microbial exposure of waste collectors of Dhaka city in Bangladesh are in poor and critical conditions. To address the present needs, proper measures should be taken by the coordinated activities (short and long-term) of both govt. and non-govt. organizations.
Inflation and Economic Growth: A Comparative Empirical Analysis Between Cameroon and the Ivory Coast
Authors: Ngouhouo Ibrahim , Nkemgha Guivis Zeufack
Published: November 2018

Inflation is the main concern of developing Countries and particularly in Ivory Coast, a leading West Africa French speaking Country. The objective of this study is to make a comparative analysis of the effect of inflation on growth between Cameroon, a French speaking Central Africa Country where inflation is not a big concern and Ivory Coast. Using the Least Squares methodology, we find that inflation has no effect on economic growth in Cameroon during the study period. However, it has a negative and significant effect on economic growth in Ivory Coast. Also, the analysis of the causal relationship between inflation and economic growth using the Toda -Yamamoto framework and the Vector Autoregressive model show that there is a unidirectional causality from inflation to economic growth in Ivory Coast, while there is no causality between these variables in Cameroon.
Working the Biosphere

Humans have arguably become a geological force that is changing the planet in profound and catastrophic ways. But what are the human practices that have such force? In this paper, we argue that work is exactly such a practice and that it is as workers that many of us are agents of global environmental change. When carbon dioxide is emitted or forests are cut down, someone is working. Yet we lack adequate descriptive and normative theories of work to understand how we are a geological force. In this paper, we suggest possible beginnings for an environmental philosophy of work.
Current Scenarios for the Demographic Future of the World: The Cases of Russia and Germany
Authors:   Lomonosov Moscow State University, Iontsev Vladimir A. , Subbotin Alexander A. ,   Lomonosov Moscow State University
Published: November 2018

In this article, we explore the demographic future of the world with a focus on scenarios for Russia and Germany. We seek an alternative to the Western standards of scenarios for global demographic development. We consider demographic development both in a positive and negative sense. Our analysis rests on such theoretical structures as the general theory of population, the classical theory of demographic transition, the concepts of the ‘second’, ‘third’, and ‘fourth’ demographic transitions, and scenarios for the ‘Eurasian demographic development path’. We employ a range of methods from comparative demography as well as historical analogies, expert evaluations and demographic forecasts. We analyse the patterns of current demographic development in Russia and Germany to explore various demographic scenarios. In the conclusion, we stress the need for Russia and other countries, including Germany, to embark on the ‘Eurasian demographic development path’ in view of the countries’ geographical positions and demographic values, with children being a dominant one. Otherwise, both Germany and Russia may disappear as national states as early as this century. The findings of this study can be used to improve the demographic policies of Russia and Germany.
Introduction to the thematic file

This chapter aims at a better understanding of the dynamics leading firms to create Networks of practice (NoP) to transfer knowledge and know-how between its geographically dispersed business units. In this introduction we focus on the complementarity between communities of practice (CoP) and networks of practice (NoP) inside firms to share knowledge and consolidate organizational learning. We show that informal settings where people interact around their practices, such as CoP facilitate and consolidate knowledge sharing inside firms and enable them to create a larger network. After a literature review on CoP and NoP, the chapter will highlight the role of CoP and boundaries processes (brokers, boundary objects) in the development of NoP.
Le rôle des communautés de pratiques et de leur coordination dans le développement et le déploiement des innovations dans une multinationale

Published: November 2018

La littérature met en avant le rôle des communautés de pratique (CoPs) dans la constitution et le partage de connaissances tacites et ancrées. Cependant, leur impact sur les processus d’innovation reste l’objet d’un débat. Nous nous attachons à mieux comprendre le rôle des CoPs dans l’innovation à l’échelle d’une firme multinationale. A partir de l’étude de cas approfondie d’une innovation développée au sein d’une filiale et déployée dans une autre, nous montrons le rôle critique de l’implication conjointe de deux CoPs de natures différentes, l’une pilotée et soutenue par le top management et l’autre autonome et spontanée. Nous spécifions les modes de coordination entre ces CoPs qui ont soutenu le développement et le déploiement de l’innovation dans la FMN.
Le projet d’exploration au prisme d’une théorie sociale de l’apprentissage
Authors: Bonnet Emmanuel , Lièvre Pascal , Godé Cécile
Published: November 2018

L’objet de cet article est d’étudier un projet d’exploration en mobilisant une théorie sociale de l’apprentissage initialement associée à la communauté de pratique (Wenger, 1998). D’une part, les projets d’exploration sont abordés sous l’angle de l’apprentissage collectif plutôt que de la coordination. D’autre part, l’apprentissage situé ne se réduit pas aux communautés de pratique (Amin et Roberts, 2008). Nous proposons d’articuler projet d’exploration et théorie sociale de l’apprentissage et posons la question suivante : quels enseignements théoriques et empiriques pouvons-nous dégager de l’étude d’une équipe projet d’exploration à travers le prisme d’une théorie sociale de l’apprentissage ? A partir du cas d’une simulation d’exploration martienne, nous montrons que le projet peut être abordé comme une dynamique de structuration qui articule sens, participation et réification. Nos résultats nous permettent de mieux comprendre l’apprentissage collectif en situation dans des projets d’exploration.
The Local and Global Knowledge Dynamics through Communities. The Case of Communities of Makers and Social Entrepreneurs in Barcelona
Authors: Capdevila Ignasi
Published: November 2018

Previous research has underlined the multiscalar character of the knowledge dynamics that are involved in the localized innovation processes. The article studies two types of communities of practice (CoPs) outside organizations located in Barcelona, by taking a community-based view of their local and global linkages. At the local level, our results show that community members participate in a “local buzz” while engaging in the development of ‘local pipelines’ with other local actors. Similarly, at the global level, local communities exchange knowledge through a “global buzz” generated around networks of practice (NoPs) while creating “global pipelines” with distant actors external to the NoP.
Une lecture lakatosienne de l’approche par les écosystèmes d’affaires

Published: November 2018

La notion d’Ecosystème d’Affaires est aujourd’hui bien ancrée dans le vocabulaire managérial. Pourtant, l’existence d’un programme de recherche scientifique spécifique aux écosystèmes d’affaires reste discutée dans le monde académique. Pour démontrer l’existence d’un tel programme, nous avons réalisé une analyse qualitative diachronique exploitant une version de la méthodologie des programmes de recherche de Lakatos adaptée aux sciences de gestion. 74 articles publiés dans 22 journaux de Management Stratégique à fort facteur d’impact entre 1993 à 2014 ont été sélectionnés. L’analyse diachronique des travaux retenus démontre l’existence d’un programme de recherche dynamique et progressif connectant de nombreux construits théoriques différents.
