Phosphoregulation of the Plant Cellulose Synthase Complex and Cellulose Synthase-Like Proteins
Authors: Speicher Tori L. , Li Patrick Ziqiang , Wallace Ian S.
Published: June 2018

Cellulose, the most abundant biopolymer on the planet, is synthesized at the plasma membrane of plant cells by the cellulose synthase complex (CSC). Cellulose is the primary load-bearing polysaccharide of plant cell walls and enables cell walls to maintain cellular shape and rigidity. The CSC is comprised of functionally distinct cellulose synthase A (CESA) proteins, which are responsible for synthesizing cellulose, and additional accessory proteins. Moreover, CESA-like (CSL) proteins are proposed to synthesize other essential non-cellulosic polysaccharides that comprise plant cell walls. The deposition of cell-wall polysaccharides is dynamically regulated in response to a variety of developmental and environmental stimuli, and post-translational phosphorylation has been proposed as one mechanism to mediate this dynamic regulation. In this review, we discuss CSC composition, the dynamics of CSCs in vivo, critical studies that highlight the post-translational control of CESAs and CSLs, and the receptor kinases implicated in plant cell-wall biosynthesis. Furthermore, we highlight the emerging importance of post-translational phosphorylation-based regulation of CSCs on the basis of current knowledge in the field.
Mathematical Modeling and Simulations for Large-Strain J-Shaped Diagrams of Soft Biological Materials
Authors: Mitsuhashi Kazuhiko , Ghosh Swapan , Koibuchi Hiroshi
Published: June 2018

Herein, we study stress–strain diagrams of soft biological materials such as animal skin, muscles, and arteries by Finsler geometry (FG) modeling. The stress–strain diagram of these biological materials is always J-shaped and is composed of toe, heel, linear, and failure regions. In the toe region, the stress is almost zero, and the length of this zero-stress region becomes very large (≃150%) in, for example, certain arteries. In this paper, we study long-toe diagrams using two-dimensional (2D) and 3D FG modeling techniques and Monte Carlo (MC) simulations. We find that, except for the failure region, large-strain J-shaped diagrams are successfully reproduced by the FG models. This implies that the complex J-shaped curves originate from the interaction between the directional and positional degrees of freedom of polymeric molecules, as implemented in the FG model.
Error Sources and Distinctness of Materials Parameters Obtained by THz-Time Domain Spectroscopy Using an Example of Oxidized Engine Oil
Authors: Méndez Aller Mario , Abdul-Munaim Ali Mazin , Watson Dennis G. , Preu Sascha
Published: June 2018

Gasoline engine oil (SAE 5W-20) was subjected to thermal oxidization (TO) for four periods of time (0 h, 48 h, 96 h and 144 h) and exposed to THz-time domain spectroscopy (TDS) measurement. Error contributions from various error sources, such as repeatability errors, assembly errors of the probe volume and errors caused by the TDS system were evaluated with respect to discernibility and significance of measurement results. The most significant error source was due to modifications of the TDS setup, causing errors in the range of 0.13% of the refractive index for samples with a refractive index around 1.467 and a probe volume length between 5 and 15 mm at 1 THz. The absorption coefficient error was in the range of 8.49% for an absorption around 0.6 cm−1. While the average of measurements taken with different setup configurations did not yield significant differences for different TO times, a single, fixed setup would be able to discern all investigated oil species across the entire frequency range of 0.5–2.5 THz. The absorption coefficient measurement showed greater discernibility than the measurement of the refractive index.
A Computational Model of Watermark Algorithmic Robustness Capable of Resisting Image Cropping for Remote Sensing Images
Authors: Tong Deyu , Ren Na , Shi Wenzhong , Zhu Changqing
Published: June 2018

Various watermarking algorithms have been studied to better enable the copyright protection of remote sensing images. The robustness of such algorithms against image cropping attacks has subsequently been verified mainly by various experiments. However, to date, the experimental results are subject to the differences in experimental factors and computational resource costs. Hence, the study presented in this paper proposes a robustness computation model of watermarking remote sensing images in terms of the image cropping attack. The robustness computation model consists of three parts: analysis principles, an evaluation index, and a computation method. The robustness analysis principles are provided based on the salient features of watermarking remote sensing images and attacking properties. A probability-based evaluation index is then defined to more comprehensively measure the robustness of different algorithms. The computation method developed in this study is based on permutations and the inclusion-exclusion principle to theoretically calculate robustness. The experiments conducted to verify the effectiveness of the computation model, revealed true closeness between both the calculated and experimental results. Finally, the relationships between the robustness and the different parameters used in the watermarking algorithms are investigated by using the proposed computation model.
Tax Constraints, Social Policy Preferences, and Support for Redistribution
Authors: Naumann Elias
Published: June 2018

The aim of this paper is to explore whether support for the welfare state is lower if people are made aware of its costs. Using data from a series of survey experiments in the German Internet Panel, we analyse individual spending preferences for different areas of the welfare state and support for redistribution. Tax constraints lead to lower support for unemployment benefits and for redistribution. Tax constraints do not affect support for more spending on pensions, healthcare, and long-term care. We consider whether the effect of tax constraints varies with pre-existing political attitudes or with individual material circumstances. We find little evidence that a political ideology makes respondents more responsive to tax constraints. However, we find some support that low income respondents are less responsive to the tax constraint and maintain their high support despite its costs. Attitudes towards the welfare state are not independent of attitudes towards taxation, and we conclude that our understanding of public attitudes might considerably benefit from combining these different strands of the literature.
Conflict between Freedom of Expression and Religion in India—A Case Study
Authors: Singh Amit
Published: June 2018

The tussle between freedom of expression and religious intolerance is intensely manifested in Indian society where the State, through censoring of books, movies and other forms of critical expression, victimizes writers, film directors, and academics in order to appease Hindu religious-nationalist and Muslim fundamentalist groups. Against this background, this study explores some of the perceptions of Hindu and Muslim graduate students on the conflict between freedom of expression and religious intolerance in India. Conceptually, the author approaches the tussle between freedom of expression and religion by applying a contextual approach of secular-multiculturalism. This study applies qualitative research methods; specifically in-depth interviews, desk research, and narrative analysis. The findings of this study help demonstrate how to manage conflict between freedom of expression and religion in Indian society, while exploring concepts of Western secularism and the need to contextualize the right to freedom of expression.
Measuring the Economic Benefits of Industrial Natural Gas Use in South Korea
Authors: Kim Hyo-Jin , Han Su-Mi , Yoo Seung-Hoon
Published: June 2018

Natural gas (NG) is an important input used in the industrial production of South Korea. Therefore, the government requires quantitative information to be provided about the economic benefits of industrial NG (ING) use to decide whether to invest in expanding the supply of ING or not. This manuscript tries to measure the economic benefits of NG use in the manufacturing industry by using a specific case in South Korea. For this purpose, a trans-log production function is estimated using the data collected from a national survey of 1100 firms in South Korea. Of them, 299 firms used ING. For a representative manufacturing firm, the point estimated for the economic benefits of ING use is obtained as KRW 2409 (USD 2.07) per m3, which is statistically meaningful. The average price of ING, which is defined as the total expenditure on ING purchased in 2016 and divided by the total amount of ING purchased in 2016, was KRW 667 (USD 0.57) per m3. Therefore, the economic benefits of ING use are 3.61 times as great as the average price of ING. This implies that ING produces more value than its price in South Korea.
Decarbonization Pathways for International Maritime Transport: A Model-Based Policy Impact Assessment
Authors: Halim Ronald , Kirstein Lucie , Merk Olaf , Martinez Luis
Published: June 2018

International shipping has finally set a target to reduce its CO2 emission by at least 50% by 2050. Despite this positive progress, this target is still not sufficient to reach Paris Agreement goals since CO2 emissions from international shipping could reach 17% of global emissions by 2050 if no measures are taken. A key factor that hampers the achievement of Paris goals is the knowledge gap in terms of what level of decarbonization it is possible to achieve using all the available technologies. This paper examines the technical possibility of achieving the 1.5° goal of the Paris Agreement and the required supporting policy measures. We project the transport demand for 6 ship types (dry bulk, container, oil tanker, gas, wet product and chemical, and general cargo) based on the Organization for Economic Co-operation and Development’s (OECD’s) global trade projection of 25 commodities. Subsequently, we test the impact of mitigation measures on CO2 emissions until 2035 using an international freight transport and emission model. We present four possible decarbonization pathways which combine all the technologies available today. We found that an 82–95% reduction in CO2 emissions could be possible by 2035. Finally, we examine the barriers and the relevant policy measures to advance the decarbonization of international maritime transport.
Job Loss in a Group of Older Canadian Workers: Challenges in the Sustainable Labour Market Reintegration Process
Authors: Fournier Geneviève , Zimmermann Hélène , Masdonati Jonas , Gauthier Christine
Published: June 2018

In Western countries, the loss of jobs among older workers is a highly worrisome situation, since it can be synonymous with long-term employment precariousness and definitive exclusion from the labour market. This precariousness is occurring while the labour force in these countries is aging, and governments are looking to extend people’s working lives. It is therefore particularly relevant to study different labour market reintegration processes and to understand their sustainability from a psychological perspective. The present article is examining these processes using a longitudinal study over an 18-month period with 61 older Canadian workers. Time 1 and Final Time were documented with semi-structured individual interviews. These data allowed us to qualitatively construct three reintegration processes (blocked, downgrading, and sustainable) that describe a large spectrum of workers’ experiences regarding occupational repositioning. Quantitative analyses likewise suggest moderate statistical links between the reintegration process and changes in subjective variables associated with the relationship to work and identity representations. Altogether, the results underline the importance of returning to the labour market in qualified, decent, sustainable work that allows people to have a decent and meaningful personal life. The results also suggest, in keeping with the psychology of sustainability, that interventions should promote occupational and personal enrichment, both at the individual and organizational levels.
Spatial Variation of Urban Thermal Environment and Its Relation to Green Space Patterns: Implication to Sustainable Landscape Planning
Authors: Wu Zhijie , Zhang Yixin
Published: June 2018

The rapid changes of land covers in urban areas are one of major environmental concerns because of their environmental impacts. Such land cover changes include the transformation of green space to impervious surface, and the increase of land surface temperature (LST). The objective of this study was to examine the spatial variation of urban landscape composition and configuration, as well as their influences on LST in Suzhou City, China. Landsat-8 image was processed to extract land covers and retrieve LSTs that were used to study relationship between spatial variation of LST and land covers. The results indicated that there was a significantly negative correlation between mean LST and green space coverage along the urban–rural gradients. With every 10% increased green space coverage, the mean LST drop was about 1.41 °C. A grid-base analysis performed at various grid sizes indicated that an increase in the percentage of surface water body area has a greater cooling effect of the mean LST than a vegetation increase. The mean LST had a significantly negative correlation with both the shape and aggregation indexes of the green space patches. Our results suggest that the sustainable landscape planning of green space in a typical city with a large water area should include both the vegetation and the surface water covers. The increased percentage of vegetation and surface water covers had the greatest cooling effect on an urban thermal environment, which is one of the ecosystem services that green space provides. A dense distribution of green space patches with complex shapes should be considered in urban sustainable landscape planning for increasing ecosystem services.

Published: June 2018

Assessing the water footprint (WF) of crops is key to understanding the agricultural water consumption and improving water use efficiency. This study assessed the WF of wheat and maize in the Haihe River Basin (HRB) of Northern China over the period1956–2015, including rain-fed, sufficient, and insufficient irrigation conditions by different irrigation intensity to understand the agricultural water use status. The major findings are as follows: (1) The annual average total WF of wheat and maize production is 20.1 (52% green, 29% blue, and 19% grey) and 15.1 (73% green, 3% blue, and 24% grey) billion m3 year−1, respectively. The proportion of grey WF is much larger than the world average; (2) Wheat has larger unit WF (1580 m3 t−1) than maize (1275 m3 t−1). The unit WF of both wheat and maize shows exponentially decreasing trends, indicating that water use efficiency has been improved. The unit WF is heterogeneous in space, which is larger in Tianjin and Huanghua and smaller in the Southern HRB; (3) Rain-fed crops have the largest unit WF, followed by crops under insufficient and sufficient irrigation conditions for both wheat and maize. To improve the sustainability of water resources, the application of fertilizer must be reduced, and irrigation is an effective way to improve water use efficiency in water-abundant areas.
Informal Settlements and Flooding: Identifying Strengths and Weaknesses in Local Governance for Water Management
Authors: Williams David Samuel , Máñez Costa María , Celliers Louis , Sutherland Catherine
Published: June 2018

Urbanization and climate change are compounding the vulnerability of flooding for the urban poor, particularly in the Global South. However, local governance can be a greater determinant of flood risk than the hazard itself. Identifying strengths and weaknesses in local governance for water management is therefore crucial. This paper presents a governance assessment for Quarry Road West informal settlement, Durban, South Africa, in relation to flood risk by applying the Capital Approach Framework. Through developing a deeper understanding of the current governance system, the embeddedness of several social values can also be gauged. This is important particularly for integrative and transdisciplinary management of flood risk, enacted in the case of Quarry Road West informal settlement through the Palmiet Rehabilitation Project, a multi sector partnership at the climate change and water governance interface. Findings from this study indicate that, currently, climate change adaptation remains a challenge for decision-makers and policy-planners. A more effective integration of the residents of Quarry Road West informal settlement into local governance for water management is urgently needed. This is particularly important in the context of informal settlements that are marginalized and often lacking governance mechanisms to affect change.
La numérisation du dossier d’oeuvre : enjeux organisationnels pour les musées

Digitization of Object File in Museum : Organizational Issues.

Documentary production, reflecting the organization, often created by many actors around the same process, is a subject of important analysis of the practices of these actors and the evolution of that process. The inventory of heritage, traditionally based on strong documentary component practices involving multiple actors in a common process illustrates this. Indeed, museums, having always followed the technical and social developments in recent centuries have integrated new technologies of information and communication both in their mediation and within their internal organization. However, the prospect of a digitized object file establishes a different contribution to the document and brings actors to question the process based on paper.
Documentation et muséalisation de la performance
Authors: Giguère Amélie
Published: June 2018

Documentation and Musealisation of Performance.

The musealisation of performance seems to be a controversial activity. First, the performance is, by nature, short-lived and mainly focuses on the performer’s body. This is very different from the traditional art objects museums are used to display. Then, the recording, or other “associated information”, are often discarded as secondary or perceived as remnants. Nowadays, museums and FRAC integrate performances in their collections through strategies which tend to preserve the integrity of the artists’ view. Through this study of the musealisation of two performances -Autoportrait(s) by Gina Pane and Intime et personnel by Esther Ferrer – respectively at the Musée national d’art moderne du Centre Pompidou and at the FRAC in Lorraine, this article shows that strategies can be implemented during the “selection” and “presentation” of performances or associated objects and that documentation plays a key role in this process. Finally, this article argues that documentation is not always second best to the performances themselves in the musealisation process. How to manage this delicate balance between the documentation and the performance, and the knowledge related to them, is crucial for the musealisation process.
Écrire l’histoire des expositions : réflexions sur la constitution d’un catalogue raisonné d’expositions

Published: June 2018

Writing the history of exhibitions : reflections on the framing of a catalogue raisonné of exhibitions.

If museum objects and artefacts need to be documented, how can we account for the work of the museum in its most visible form, namely the exhibition ? The article aims at questioning the notion of the catalogue, in its various forms, taking into account its recent evolution in respect to the exhibition. Indeed, is the principle of establishing the most complete inventory of the work of an artist or collection applicable to an institution production in the form of exhibitions ? The Centre Georges-Pompidou appears as an exemplary case study. In the framework of its program of research and globalization, this institution develops, since 2010, a reflection on exhibitions history. Analysing this initiative thought for facilitating the documentation and cataloguing of all exhibitions while focusing on the critical success of past initiatives, will allow us to consider the exhibition as a cultural object that can be historically put into perspective.
The Importance of Geospatial Data to Labor Market Information
Authors: Johnson Eric M. , Urquhart Robert , O'Neil Maggie
Published: June 2018

School-to-work transition data are an important component of labor market information systems (LMIS). Policy makers, researchers, and education providers benefit from knowing how long it takes work-seekers to find employment, how and where they search for employment, the quality of employment obtained, and how steady it is over time. In less-developed countries, these data are poorly collected, or not collected at all, a situation the International Labour Organization and other donors have attempted to change. However, LMIS reform efforts typically miss a critical part of the picture—the geospatial aspects of these transitions. Few LMIS systems fully consider or integrate geospatial school-to-work transition information, ignoring data critical to understanding and supporting successful and sustainable employment: employer locations; transportation infrastructure; commute time, distance, and cost; location of employment services; and other geographic barriers to employment. We provide recently collected geospatial school-to-work transition data from South Africa and Kenya to demonstrate the importance of these data and their implications for labor market and urban development policy.

Published: June 2018

Supernova (SN) 1987A in the Large Magellanic Cloud (LMC) has proven to be a unique laboratory within which to investigate particle acceleration in young supernova remnants (SNRs). Here we report the first detection of linear polarization of the supernova’s synchrotron emission from imaging observations at frequencies spanning from 20 to 50 GHz, carried out with the Australia Telescope Compact Array (ATCA) between 2015 October and 2016 May. The direction of the radio polarization, corrected for Faraday rotation, points to a primarily radial magnetic field across the inner ring, encompassing both the reverse and forward shocks. The magnetic field strength peaks over the high-emissivity eastern sites, where efficient cosmic-ray acceleration likely takes place under quasi-parallel shocks at high Mach numbers. The mean fraction of polarized emission in the brightest sites is 2.7% ± 0.2% at 22 GHz and 3.5% ± 0.7% at 44 GHz. In the inner remnant, non-radial components of the polarized emission appear to be more prevalent. However, the low significance detection in the central regions limits interpretation.

Published: June 2018

Natural hybridization between species provides an opportunity to study the mechanisms that maintain independent lineages and may help us understand the process of speciation. The New Zealand tree wētā speciesHemideinathoracicaproduces F1hybrids where it lives in sympatry with two closely related species:HemideinacrassidensandHemideinatrewicki. This study looked at the viability and fertility of F1hybrid wētā betweenH.thoracicaandH.crassidensthat were collected from the wild and kept in captivity. The hybrids appeared to have normal viability from the late juvenile stage, with all male wētā maturing at a late instar. Male F1hybrids displayed normal mating behavior and one male produced offspring in captivity. In contrast to Haldane’s rule, female F1hybrids appeared to be infertile; they refused to mate and did not produce eggs. No evidence ofWolbachiainfection was identified in any of the three North IslandHemideinaspecies.
In honor of conservation of the Brazilian Atlantic Forest: description of two new damselflies of the genus Forcepsioneura discovered in private protected areas (Odonata: Coenagrionidae)
Authors: Pinto Ângelo Parise , Kompier Tom
Published: June 2018

Two new Brazilian Protoneurinae damselflies,Forcepsioneurareguasp. nov. (holotype male deposited in DZRJ: Brazil, Rio de Janeiro State, Cachoeiras de Macacu municipality, RPPN Reserva Ecológica de Guapiaçu) andForcepsioneuraserrabonitasp. nov. (holotype male deposited in DZRJ: Brazil, Bahia State, Camacan municipality, RPPNs Serra Bonita) , are described, illustrated and diagnosed based on males and females. The bluish and smallerF.reguasp. nov. has been confused with at least three previously described species, being very similar to the type species ofForcepsioneura,F.garrisoniLencioni, 1999, but lacking a defined tubercle-like process on the posterolateral margin of the median lobe of the prothorax in both sexes, which allows it to be distinguished from all other known species. The shape of the cercus of the male ofF.serrabonitasp. nov. is similar to that ofF.grossiorumMachado, 2001 andF.luciaMachado, 2000, two species with very short ventrobasal process. However, it differs from them mainly by the mediobasal process of the cercus, which is rounded in dorsal view and almost not visible in lateral view. The taxonomic status ofForcepsioneurais discussed and a comparison with the other species of the genus is provided. Based on size, habitat and coloration,Forcepsioneuracan be informally divided into two groups: (1) large, orange-black and montane species, includingF.grossiorum,F.itatiaiae(Santos, 1970),F.luciaandF.serrabonitasp. nov.; (2) small, bluish and lowland species, includingF.garrisoni,F.haerteliMachado, 2001,F.reguasp. nov. andF.sancta(HageninSelys, 1860). Our findings highlight the urgency in directing collecting efforts to unexplored areas, as well as the importance of private preserves that harbor the type localities as guardians of the threatened and diverse Atlantic Forest diversity. Together these two localities surveyed account for more than 210 species of odonates, representing almost 24% of the number of Brazilian species. Brazil has the greatest number of known species of odonates in the world. This study shows that further research is required in order to fully understand the diversity ofForcepsioneura.

La structure spatiale des systèmes régionaux d’innovation : qu’en est-il de la proximité géographique au sein des pôles de compétitivité wallons ?
Authors: Wilmotte Pierre-François , Halleux Jean-Marie
Published: June 2018

La recherche sur les systèmes régionaux d’innovation souffre d’un manque de clarté quant à la manière dont ces systèmes s’organisent dans l’espace. Pour clarifier cette question, nous testons empiriquement, grâce à des données sur les projets de recherche et développement des pôles de compétitivité wallons, l’hypothèse théorique selon laquelle la probabilité que deux acteurs collaborent pour innover est corrélée à la distance spatiale les séparant. Nos analyses utilisent la différenciation entre les logiques de «  local buzz  » et de «  global pipelines  », formulée par le modèle de référence de Harald Bathelt et al . (2004). Nos résultats mettant en exergue le caractère structurant du niveau régional wallon, nous proposons une amélioration de ce modèle en le complétant par la référence aux logiques en «  regional pipelines  ». Il ressort également de nos résultats que les relations entre partenaires de projets de recherche et développement sont particulièrement intenses lorsque la distance spatiale les séparant est inférieure à dix kilomètres, ce qui témoigne d’une significative dynamique en «  local buzz  ».
D’une mise en culture du transitionnel démis
Authors: Corcos Maurice , Loisel Yoann
Published: June 2018

Les activités thérapeutiques pour l’adolescent limite sont envisagées comme support d’un travail transitionnel de mise en culture du sens de soi. Leurs conditions effectives d’investissement par le patient reposent largement sur l’investissement par le soignant d’une enveloppe globale du dispositif thérapeutique, souple et résistante, maintenue par la culture institutionnelle. L’antécédent fréquent de psychotraumatisme, voire son inévitable présence comme cicatrice irritative du fonctionnement limite, selon la description d’un « complexe traumatique », confirme la nécessité du soin par la relation autant que celle de l’aménagement d’une certaine prudence dans cette relation. À ces conditions, la médiation thérapeutique tient un espace de co-éprouvé soignant-soigné. Elle peut procéder aussi d’un processus de cocréation qui valide la sécurité du cadre soignant autant qu’elle soutient et valorise la créativité du patient.
Quand la prévention mène au jeu : la création du jeu SANTÉ’TOUR
Authors: Despet Camille
Published: June 2018

Compte tenu de la volonté du gouvernement de renforcer les politiques de santé en direction des jeunes, une unité de la Fondation santé des étudiants de France, l’ u.t.t.a.c. (Unité de traitement des troubles de l’affectivité et de la cognition), a décidé de mettre en place un atelier de prévention. L’objectif est de faire acquérir des connaissances dans le domaine de la nutrition, des médicaments, de la sexualité et de la sécurité au quotidien. En raison de l’absence d’outils adaptés, des professionnels de cette unité se sont attelés à penser un support permettant de médiatiser l’effet d’apprentissage. Toute la conception de cet outil repose sur un corpus théorique allant du choix du jeu comme vecteur motivationnel à celui du style d’animation. Les trois années d’utilisation ont démontré l’amélioration des connaissances après l’utilisation de SANTÉ’TOUR et le plaisir retrouvé par les jeunes à penser. Face à ce constat, nous avons souhaité diffuser notre jeu, qui est depuis janvier en vente grâce aux éditions Valoremis. Les quelques retours actuels témoignent de la facilité de la prise en main par des professionnels aux profils très divers et d’une recrudescence de la curiosité des adolescents qui interpellent davantage les adultes sur ces questions.
Empathie et capacités narratives chez les jeunes porteurs de TSA : l’intérêt de la narrativité vidéo-ludique
Authors: Duris Olivier
Published: June 2018

Animant des ateliers à médiation numérique auprès d’enfants porteurs de tsa depuis quelques années, nous avons pu relever chez eux un rapport au jeu vidéo relevant essentiellement d’une interaction sensorielle et motrice. Pour ces enfants, chez qui les repères narratifs sont extrêmement fragiles, mettre du sens sur des images et sur l’histoire qu’elle véhicule peut être très compliqué. Nous proposons ainsi d’aborder dans cet article un autre intérêt de la médiation numérique pour les enfants porteurs de tsa : la narration, qui, lorsqu’elle se combine à l’attention conjointe et à l’interaction ludique, permet d’améliorer le rapport de l’enfant autiste à la temporalité, sa capacité à ordonner une histoire, mais également ses capacités d’empathie.
Les femmes indiennes - Un masala d’identités. Revue de littérature dans le monde indien et en migration
Authors: Vijayaratnam Mélanie , Moro Marie Rose
Published: June 2018

On ne les connaît que trop peu ces femmes indiennes, pourtant nous les rencontrons de plus en plus dans notre clinique transculturelle. L’Inde est une terre de contrastes où les femmes sont souvent sujettes à de faciles clichés. Elles sont souvent écrasées sous le poids d’une société patriarcale, soumises aux mariages arrangés, contraintes de procréer. Pourtant, c’est dans le même temps cette féminité qui est vénérée et redoutée car considérée comme une tyrannique shakthi. Qui sont-elles, ces femmes indiennes, au cœur de plusieurs discours et plusieurs représentations ? Que deviennent-elles en situation migratoire et transculturelle ? Loin de cliver ces deux Indes et ses multiples représentations de la féminité, notre article vise plutôt à les articuler, à considérer le traditionnel dans le moderne, la puissance dans la soumission, la pin-up dans la déesse, le sexuel dans le religieux voire le traditionnel dans la migration.
L’inoculation de la petite vérole à Lyon : de la condamnation à l’acceptation (1779-1811)
Authors: Boarini Serge
Published: June 2018

La contribution porte sur la construction de la perception des risques ou des dangers en matière de santé à l’occasion d’un moment de crise, l’inoculation de la petite vérole. Pour cela, elle part de l’exemple de la condamnation en 1779 d’un négociant et du médecin qui a inoculé ses deux enfants, dans la ville de Lyon. Alors que l’inoculation est perçue comme un danger en 1779, elle va s’établir progressivement comme un procédé sûr si bien qu’au moment du triomphe de la vaccination, loin d’être jetée aux oubliettes de l’histoire de la santé, elle va au contraire être consacrée comme un procédé fiable et valide. Les péripéties de l’histoire du médecin Michel O’Ryan, de la condamnation à la reconnaissance, fournissent le fil directeur de la construction du risque sanitaire. La contribution dégagera les conditions requises pour qu’un risque sanitaire soit perçu comme tel. Elle esquissera enfin les principes d’une étude de l’écriture des risques sanitaires.
A Rubric to Assess Students' Clinical Reasoning When Encountering Virtual Patients
Authors: Georg Carina , Karlgren Klas , Ulfvarson Johanna , Jirwe Maria , Welin Elisabet
Published: June 2018

Background:

Training with virtual patients has been proposed as a suitable learning activity to improve clinical reasoning skills for nursing students. However, published instruments with the capacity to assess students' reasoning process in the encounter with virtual patients are lacking.

Method:

Deductive and abductive analyses were used to adapt the Lasater Clinical Judgment Rubric (LCJR) to assess nursing students' clinical reasoning skills in the encounter with virtual patients. The new rubric's ability to capture nursing students' clinical reasoning processes was tested using deductive analysis and statistical analysis.

Results:

A grading rubric for virtual patients, the vpLCJR, was developed. Cronbach's alpha showed .892, indicating good internal consistency.

Conclusion:

The rubric vpLCJR, which deconstructs aspects of clinical reasoning for both students and faculty members, can be used to clarify expectations, assess students' clinical reasoning process, and provide feedback for learning when nursing students encounter virtual patients. [

Developing a Culture of Caring and Support Through a Peer Mentorship Program
Authors: Kramer Deborah , Hillman Sandra M. , Zavala Mirian
Published: June 2018

Background:

Academic leaders are concerned about the retention rate of nursing students; peer mentoring may be one strategy for student success. Research studies on mentoring indicate the benefits of mentoring accrue for both mentors and mentees.

Method:

A peer voluntary mentorship program operated in coordination with an academic resource center for a decade. It included training and weekly meetings. Mentors were senior nursing students who had a minimum B
+
average and faculty recommendations. All mentors kept journal logs of their time and reflections of their experience.

Results:

Journal statements revealed that mentored nursing students felt more successful in their coursework, gained test-taking skills, and did better on examinations. Mentors gained confidence about their skills and were better prepared for the NCLEX. Mentees formed a natural support group. Mentors expressed concern about their students' success beyond the program.

Conclusion:

This program generated a culture of caring and support to the nursing students, with the understanding that they would give back to others what they had received. [

Consideraciones en torno a la técnica de la encáustica grecorromana
Authors: Cuní José , Cuní Jorge
Published: June 2018

Los resultados obtenidos en el estudio analítico de algunas muestras de pintura mural romanas procedentes de Mérida parecen indicar que la materia pictórica empleada estaba compuesta por una mezcla de pigmentos y calcita aglutinados por una emulsión de cera de abejas y jabón potásico. Similares componentes fueron detectados también en otras muestras de pintura mural romana de Marsala y Complutum analizadas en este estudio. El examen de los textos griegos y latinos sobre pintura parece confirmar que tanto la composición como las características de la emulsión detectada corresponden a las de la técnica grecorromana de la encáustica, cuya composición exacta no ha sido detectada hasta la fecha y continúa siendo objeto de debate.
Ampurias en la Antigüedad Tardía. Una nueva perspectiva
Authors: Nolla J. M.
Published: June 2018

La historiografía tradicional ha venido sosteniendo que durante la Baja Antigüedad la ciudad de Ampurias no era otra cosa que el fantasma apenas tangible de su lejana grandeza. Sin embargo, una lectura atenta de los datos y un conjunto de nuevas evidencias, textuales y arqueológicas, permiten plantear los hechos de manera bien distinta y reconocer, para esta etapa histórica, un período de gran importancia para la ciudad. sede episcopal y el puerto más activo de un vastísimo territorio.
Un tipo de ánfora tardo-romana poco conocido (VLR 8.198)
Authors: Remolà Vallverdú Josep Antón
Published: June 2018

El estudio de las ánforas procedentes de diversos depósitos bajo-imperiales (siglo V d. C.) excavados recientemente en Tarragona permite caracterizar un tipo de ánfora poco conocido (VLR 8.198), de origen posiblemente oriental, cuya presencia en estos contextos tarraconenses representa un 2,6 % sobre el número total estimado de ejemplares de ánfora (606).
Campus on Fire: Indonesian Universities During the Political Turmoil of 1950s-1960s
Authors: Wahid Abdul
Published: June 2018

The 1965 Coup has deeply affected Indonesian state practice and society. In the rich body of literature that has been produced to understand the political crisis preceding the 1965 Coup —the persecution of millions of alleged communists and state discrimination against survivors and their families— higher education forms a rather under-researched sector. This study contributes to the debate on the immediate and long-term effects the 1965 event has had on Indonesian academia. It presents the situation preceding the crisis and proposes an exploratory study of what happened to public universities in several important cities in Indonesia during the political turmoil of 1965-66. Based on archival sources and interviews, the paper analyses how the anti-communist campaigns launched by Suharto’s regime in this sector has affected campuses and changed fundamentally the academic life and landscape of Indonesian public universities.
La enseñanza de los tiempos verbales en la escuela secundaria: el caso de la oposición pretérito perfecto simple versus pretérito imperfecto
Authors: Funes María Soledad , Poggio Anabella L.
Published: June 2018

En el marco del Enfoque Cognitivo Prototípico (Langacker, 1987, 1991; Lakoff, 1987; Hopper, 1988, entre otros), que parte del presupuesto de que la Sintaxis está motivada por la Semántica y la Pragmática, y por tanto, emerge del discurso, en el presente trabajo se proponen actividades para enseñar la oposición PPS-PI en la escuela secundaria. Partimos de los resultados obtenidos en un trabajo anterior, donde demostramos la hipótesis de que en la oposición pretérito perfecto simple (PPS)-pretérito imperfecto (PI), cada tiempo verbal tiene un conjunto de atributos semánticos que lo definen, dependiendo del contexto de uso y del objetivo comunicativo de los hablantes. Dichos atributos no sólo se relacionan con el aspecto verbal sino también con la función discursiva que cada tiempo cumple en un texto determinado. Para comprobar la hipótesis, conformamos un corpus de textos narrativos en los que analizamos cuantitativa y cualitativa-mente los usos de PPS y PI. El análisis de los datos reveló que el prototipo de PPS reúne los atributos de “evento concluido” y “evento puntual”; mientras que el prototipo del PI reúne, principalmente, el atributo de “descripción”. Con estos resultados, elaboramos una propuesta de enseñanza de la oposición PPS-PI para primer año de la escuela secundaria en la ciudad de Buenos Aires.

There are large omission errors in the estimation of burned area in map products that are generated at a global scale. This error is then inherited by other models, for instance, those used to report Greenhouse Gas Emissions using a “bottom up” approach. This study evaluates temporal methods to improve burned area detection using Landsat 5-TM and 8-OLI. In this process, the normalized burn ratio (NBR) was used to highlight burned areas and thresholds to classify burned and non-burned areas. In order to maximize the burned area detection two alternatives to the temporal dNBR method were evaluated: the relative form of the temporal difference RdNBR and the use of time series metrics. The processing, algorithm development and access to Landsat data was made on the Google Earth Engine GEE platform. Three regions of Latin America with large fire occurrence were selected: The Amazon Forest in Colombia, the transition from Chiquitano to Amazon Forest in Bolivia, and El Chaco Region in Argentina. The accuracy assessment of these new products was based on burned area protocols. The best model classified 85% of burned areas in the Chiquitano Forests of Bolivia, 63% of the burned areas of the Amazon Forests of Colombia and 69% of burned areas in El Chaco of Argentina.
Detección de cambios en la cobertura vegetal mediante interpretación de imágenes Landsat por redes neuronales artificiales (RNA). Caso de estudio: Región Amazónica Ecuatoriana
Authors: Jaramillo L.V. , Antunes A.F.
Published: June 2018

The interpretation of classes and change detection in the vegetation cover of large areas are activities that are made possible by the use of technologies and methods associated to Remote Sensing. Satellite images of medium and high spatial and spectral resolution are fundamental tools for the execution of projects with objectives of classification of vegetal cover and detection of its temporal variations. To exploit the use of digital information of territory recovered by the satellite images, and in order to optimize the resources invested in the tasks of classification and interpretation, it is necessary to have tools and methods that allow the automation of the processes involved and prove to be the Artificial Neural Networks (ANNs) an adequate mechanism for the execution of these processes. The main objective of this work is to validate a methodology for the identification of changes in the vegetation cover of an area located in the Ecuadorian Amazon. The applied methodology seeks the change detection in the coverage of native forests prevailing in the study region.
