The Role of Process Innovation between Firm-Specific Capabilities and Sustainable Innovation in SMEs: Empirical Evidence from Indonesia
Authors: Widya-Hasuti Afris , Mardani Abbas , Streimikiene Dalia , Sharifara Ali , Cavallaro Fausto
Published: June 2018

The importance of sustainable innovation achievement propels firms to consider the economic, social, and environmental dimensions of sustainable development. However, it is important to clarify that not all innovations impact sustainable development. Regardless of the limited circumstances in small and medium-sized enterprises (SMEs), intrapreneurship, stakeholder integration, and absorptive capacity are firm-specific capabilities that could be explored as strategic intentions of management practices in the organization. This paper investigated the mediating role of process innovation in the relationship among the firm-specific capabilities of absorptive capacity, intrapreneurship, and stakeholder integration for sustainable innovation in SMEs. This empirical study examines the manufacturing sector of Indonesian SMEs with a sample size of 190 firms. The study found that practices of process innovation, as a mediator triggered by the firm-specific capabilities of absorptive capacity, intrapreneurship, and stakeholder integration affect sustainable innovation, although at low stages. Finally, implications for the theory and practice of attaining sustainable innovation in SMEs are drawn.
Structural Formation of Cyclic Olefin Copolymer (COC) Films as Revealed by Real Time Retardation Measurements during Fast Stretching Process
Authors: Hashimoto Yoshinori , Ito Hiroshi
Published: June 2018

This work reports on an experimental study of the fast stretching of a cyclic olefin copolymer (COC) film. We measured the stress retardation of the polymer film during fast stretching and identified a relationship between stress and birefringence. This relationship indicates that the film obeys the stress optical rule (SOR) at the onset of stretching. At slower stretching speeds, the stress optical constant (SOC) settles at a certain value. With faster stretching speeds, SOC values approach the photo-elastic constant (PEC). Our study also investigated the effects of stretching temperatures and stretching modes for both uniaxial stretching and biaxial stretching. We applied techniques of thermal analysis to evaluate higher order structures after fast stretching.

Published: June 2018

To control pollutants in rivers, we need to have an understanding of the spatial and temporal variations on water quality in complex river networks. In this study, 153 sampling sties were located in Chengdu segment of Tuojiang River in 2017, 23 monitoring stations in Tuojiang River in the Chengdu segment from 2011 to 2016 were also collected. According to the data from the monitoring station, the concentrations of total nitrogen (TN), total phosphorus (TP), ammonia nitrogen (NH4+), and chemical oxygen demand (CODcr) concentrations were exceeded the water quality targets at 22, 14, 10, and 3 of the 23 monitoring stations, respectively. The regression analysis showed the NH3, TN and TP was increased from 2011 to 2016 (R2NH4+ = 0.30, p < 0.05; R2TN = 0.88, p < 0.05; R2TP = 0.30, p < 0.05), which indicated water quality was deteriorated from 2011 to 2016. In the 153 sample sites, the NH4+, CODcr, TP and TN concentrations exceeded the class III water quality threshold at 23%, 23%, 26%, and 99% of the total sampling sites, respectively. Correlation analysis showed that the main sources of NH4+, CODcr, TN, and TP (R2NH4+-CODcr = 0.572; R2NH4+-TN = 0.543; R2NH4+-TP = 0.537, p < 0.01) were municipal domestic sewage. The main pollutants in Tuojiang river network were TN and TP, high P and N concentrations probably contribute to the deterioration of surface water quality at some sampling sites (R2TPs-TP = 0.183 and R2TNs-NH4+ = 0.472, p < 0.01). TP, TN, TP in the sediments (TPs), and TN in the sediments (TNs) have accumulated in the river system because the river morphology has been changed by, for example, the damage of riparian zones and the construction of water conservation structures. The results from this study will support initiatives to improve the overall water quality and function of the river ecosystem.
Les serious games, dispositifs numériques de médiation : processus sociocognitifs et affectifs dans les usages et les effets sur les publics

Published: June 2018

The Serious Games, Digital Tools of Mediation : Sociocognitive and Emotional Processes in the Uses of and the Effects on the Public.

The serious games are emerging digital tools in science and technology museums. They aim to favor the learning of new knowledge and the development of healthy or eco-citizen behaviors by the game. Do they actually do it and how ? What are the socio-cognitive and socio-emotional processes that operate during the use of serious games by the public. After presenting a literature review, we show on the basis of an experiment recently led in the field of the environment, that serious games could elicit commitment effects favorable to the development of targeted behaviors. Finally, we open new research avenues to better understand the use process of serious games in museums.
Approximating Photo-z PDFs for Large Surveys

Published: June 2018

Modern galaxy surveys produce redshift probability density functions (PDFs) in addition to traditional photometric redshift (photo-z) point estimates. However, the storage of photo-z PDFs may present a challenge with increasingly large catalogs, as we face a trade-off between the accuracy of subsequent science measurements and the limitation of finite storage resources. This paper presents qp, a Python package for manipulating parameterizations of one-dimensional PDFs, as suitable for photo-z PDF compression. We use qp to investigate the performance of three simple PDF storage formats (quantiles, samples, and step functions) as a function of the number of stored parameters on two realistic mock data sets, representative of upcoming surveys with different data qualities. We propose some best practices for choosing a photo-z PDF approximation scheme and demonstrate the approach on a science case using performance metrics on both ensembles of individual photo-z PDFs and an estimator of the overall redshift distribution function. We show that both the properties of the set of PDFs we wish to approximate and the fidelity metric(s) chosen affect the optimal parameterization. Additionally, we find that quantiles and samples outperform step functions, and we encourage further consideration of these formats for PDF approximation.

Modern data empower observers to describe galaxies as the spatially and biographically complex objects they are. We illustrate this through case studies of four z ∼ 1.3 systems based on deep, spatially resolved, 17-band + G102 + G141 Hubble Space Telescope grism spectrophotometry. Using full-spectrum rest-UV/-optical continuum fitting, we characterize these galaxies’ observed ∼kpc-scale structures and star formation rates (SFRs) and reconstruct their history over the age of the universe. The sample’s diversity—passive to vigorously star-forming; stellar masses log

/

 = 10.5 to 11.2—enables us to draw spatiotemporal inferences relevant to key areas of parameter space (Milky Way– to super-M31–mass progenitors). Specifically, we find signs that bulge mass fractions (B/T) and SF history shapes/spatial uniformity are linked, such that higher B/Ts correlate with “inside-out growth” and central specific SFRs that peaked above the global average for all star-forming galaxies at that epoch. Conversely, the system with the lowest B/T had a flat, spatially uniform SFH with normal peak activity. Both findings are consistent with models positing a feedback-driven connection between bulge formation and the switch from rising to falling SFRs (“quenching”). While sample size forces this conclusion to remain tentative, this work provides a proof-of-concept for future efforts to refine or refute it: JWST, WFIRST, and the 30 m class telescopes will routinely produce data amenable to this and more sophisticated analyses. Such samples spanning representative mass, redshift, SFR, and environmental regimes will be ripe for converting into thousands of subgalactic-scale empirical windows on what individual systems actually looked like in the past, ushering in a new dialogue between observation and theory.

We present a spectroscopically complete sample of 147 infrared-color-selected active galactic nuclei (AGNs) down to a 22 μm flux limit of 20 mJy over the ∼270 deg2 of the Sloan Digital Sky Survey Stripe 82 region. Most of these sources are in the QSO luminosity regime (L
bol ≳ 1012
L
⊙) and are found out to z ≃ 3. We classify the AGNs into three types, finding 57 blue, unobscured Type-1 (broad-lined) sources; 69 obscured, Type-2 (narrow-lined) sources; and 21 moderately reddened Type-1 sources (broad-lined and E(B − V) > 0.25). We study a subset of this sample in X-rays and analyze their obscuration to find that our spectroscopic classifications are in broad agreement with low, moderate, and large amounts of absorption for Type-1, red Type-1, and Type-2 AGNs, respectively. We also investigate how their X-ray luminosities correlate with other known bolometric luminosity indicators such as [O iii] line luminosity (L
[O iii]) and infrared luminosity (L
6μm). While the X-ray correlation with L
[O iii] is consistent with previous findings, the most infrared-luminous sources appear to deviate from established relations such that they are either underluminous in X-rays or overluminous in the infrared. Finally, we examine the luminosity function evolution of our sample, and by AGN type, in combination with the complementary, infrared-selected, AGN sample of Lacy et al. (2013), spanning over two orders of magnitude in luminosity. We find that the two obscured populations evolve differently, with reddened Type-1 AGNs dominating the obscured AGN fraction (∼30%) for L
5μm > 1045 erg s−1, while the fraction of Type-2 AGNs with L
5μm < 1045 erg s−1 rises sharply from 40% to 80% of the overall AGN population.
Dissecting the X-Ray Emission in the Young Planetary Nebula NGC 7027
Authors: Montez Rodolfo , Kastner Joel H.
Published: June 2018

We present an analysis of a second observation of the young planetary nebula (PN) NGC 7027 by the Chandra X-ray Observatory. This latest 59.2 ks exposure with ACIS-S was acquired approximately 14 years after the initial 18.2 ks ACIS-S observation, and the improved photon statistics allow us to perform a detailed spatial and spectral analysis of the X-ray emission. Comparison with multiwavelength imaging of NGC 7027 reveals a strong anti-correlation between extinction across the nebula and the soft-band X-ray emission. Dissecting the X-ray emission into low- and high-extinction regions results in more robust characterization of the plasma spectral properties. We determine that the X-ray emitting plasma has a temperature of ∼3.6 MK, is deficient in Fe, and has an X-ray luminosity of L
X ∼ 7 × 1031 erg s−1, all of which are generally consistent with the plasma properties found in PN hot bubbles. We find no evidence of evolution in the X-ray surface brightness over the 14 year baseline between CXO observations. Our analysis underscores the importance of accounting for nebular absorption of the X-ray emission in accurately determining plasma properties for hot bubbles within PNe.

The Pulsar Arecibo L-Band Feed Array (PALFA) survey, the most sensitive blind search for radio pulsars yet conducted, is ongoing at the Arecibo Observatory in Puerto Rico. The vast majority of the 180 pulsars discovered by PALFA have spin periods shorter than 2 s. Pulsar surveys may miss long-period radio pulsars owing to the summing of a finite number of harmonic components in conventional Fourier analyses (typically ∼16), or as a result of the strong effect of red noise at low modulation frequencies. We address this reduction in sensitivity by using a time-domain search technique: the fast-folding algorithm (FFA). We designed a program that implements an FFA-based search in the PALFA processing pipeline and tested the efficiency of the algorithm by performing tests under both ideal, white-noise conditions, as well as with real PALFA observational data. In the two scenarios, we show that the time-domain algorithm has the ability to outperform the FFT-based periodicity search implemented in the survey. We perform simulations to compare the previously reported PALFA sensitivity with that obtained using our new FFA implementation. These simulations show that for a pulsar having a pulse duty cycle of roughly 3%, the performance of our FFA pipeline exceeds that of our FFT pipeline for pulses with dispersion measure ≲ 40 pc cm−3 and for periods as short as ∼500 ms, and that the survey sensitivity is improved by at least a factor of two for periods ≳ 6 s. Early results from the implementation of the algorithm in PALFA, including discoveries, are also presented in this paper.
Solar Cycle Observations of the Neon Abundance in the Sun-as-a-star
Authors: Brooks David H. , Baker Deborah , Driel-Gesztelyi Lidia van , Warren Harry P.
Published: June 2018

Properties of the Sun’s interior can be determined accurately from helioseismological measurements of solar oscillations. These measurements, however, are in conflict with photospheric elemental abundances derived using 3D hydrodynamic models of the solar atmosphere. This divergence of theory and helioseismology is known as the “solar modeling problem.” One possible solution is that the photospheric neon abundance, which is deduced indirectly by combining the coronal Ne/O ratio with the photospheric O abundance, is larger than generally accepted. There is some support for this idea from observations of cool stars. The Ne/O abundance ratio has also been found to vary with the solar cycle in the slowest solar wind streams and coronal streamers, and the variation from solar maximum to minimum in streamers (∼0.1–0.25) is large enough to potentially bring some of the solar models into agreement with the seismic data. Here we use daily sampled observations from the EUV Variability Experiment on the Solar Dynamics Observatory taken in 2010–2014, to investigate whether the coronal Ne/O abundance ratio shows a variation with the solar cycle when the Sun is viewed as a star. We find only a weak dependence on, and moderate anti-correlation with, the solar cycle with the ratio measured around 0.2–0.3 MK falling from 0.17 at solar minimum to 0.11 at solar maximum. The effect is amplified at higher temperatures (0.3–0.6 MK) with a stronger anti-correlation and the ratio falling from 0.16 at solar minimum to 0.08 at solar maximum. The values we find at solar minimum are too low to solve the solar modeling problem.
Fiscal federalism and regional performance in Russia
Authors: Di Bella Gabriel , Dynnikova Oksana , Grigoli Francesco
Published: June 2018

Sound regional policies are essential for balanced and sustained economic growth. The interaction of federal and regional policies with cross-regional structural differences affects human and physical capital formation, the business climate, private investment, market depth, and competition. This paper summarizes the main elements of Russia’s fiscal federalism, describes the channels through which it operates, and assesses the effectiveness of regional transfers in reducing regional disparities. The results suggest that federal transfers to regions contributed to reducing disparities arising from heterogeneous regional tax bases and fiscal revenues. This allowed regions with initially lower per capita income to increase human and physical capital at higher rates. There is little evidence for transfers contributing to increased cross-regional growth synchronization. The results also suggest that federal transfers did not significantly improve regional fiscal sustainability, a conclusion that is supported by the lack of convergence in per capita real income across Russian regions in the last 15 years.
L’Eurasie, un impensé de la géographie : continent, empire, idéologie ou projet ?
Authors: Bruneau Michel
Published: June 2018

Les géographes se sont rarement référés à l’Eurasie. Aujourd’hui, le projet russe d’Union économique eurasiatique et chinois des nouvelles routes de la soie modifie notre façon de considérer ce continent et son enveloppe maritime à l’aide d’une approche géohistorique. Ses deux extrémités ouest et est s’étant d’abord en grande partie ignorées, il a été caractérisé jusqu’au début du xx e siècle par la récurrence de constructions impériales. La généralisation de l’État-nation a accentué sa fragmentation et les zones de fractures ou de guerres récurrentes aux marges des anciens empires devenus de grandes puissances. Les corridors qui sont aménagés, en cours d’aménagement ou en projet, continentaux ou maritimes, font l’Eurasie. La Chine s’affirme comme le moteur principal du développement des infrastructures de transports et de communications qui donneront plus de cohésion à cet ensemble continental. D’impensé géographique, celui-ci risque de devenir un espace signifiant.

Published: June 2018

Les flux migratoires sont souvent privilégiés pour appréhender l’organisation spatiale des territoires. Avec l’explosion des grandes bases de données et des technologies de l’information, de nouveaux outils (méthodes et données) sont mis à disposition des chercheurs. Deux méthodes de partitionnement spatial sont éprouvées sur la même base de données relationnelles : Anabel (développée par l’ Insee ) et la méthode de Louvain (issue des sciences des données). L’objectif est de comparer leurs avantages et inconvénients, tout en apportant une lecture géographique critique des résultats obtenus à partir d’un jeu de données théoriques, et d’un jeu de données réelles (migrations inter-communales en Belgique, sans tenir compte des migrations intra-communales). Les résultats rappellent que partitionner un espace n’est pas un exercice anodin, que les résultats dépendent fortement des méthodes et seuils utilisés, et que la prise de décision liée au partitionnement du territoire devrait toujours être prudente et avisée.
14/18 : d’où est-ce que cela commence ?
Authors: Matta Ramuntcho
Published: June 2018

De son trajet de vie personnel, narré dans un style modeste et sensible, l’auteur tire sinon un enseignement, du moins un être au monde où le silence et la mort ont fait place au son et aux mots. La psychothérapie institutionnelle est passée par là. Un lieu vient symboliser son plaisir d’agir, optant pour le contournement, la marge, la douceur, l’art. Lizières, lieu de production, évoluera vers un décentrement, pour intervenir dans des endroits tels que les prisons, les établissements scolaires. La rencontre d’une adolescence « en tranchée », coincée dans l’ornière d’une période douloureuse, de 14 à 18 ans, est relatée avec simplicité. Une découverte mutuelle s’opère devant nos yeux, par le biais d’une médiation qui serait avant tout la légèreté et le respect.
Le jeu d’acteur ? Un jeu d’enfant ! L’expression scénique : une médiation au carrefour de la créativité et du thérapeutique
Authors: Meyer Pascal
Published: June 2018

Cet article présente le travail d’un éducateur, ex-comédien et metteur en scène de théâtre, au sein d’un dispositif médico-social itep/sessad (Institut thérapeutique éducatif pédagogique / Service d’éducation spécialisé et de soins à domicile). Depuis octobre 2013, ce professionnel anime, dans le cadre de prises en charge d’enfants qui manifestent des troubles du comportement, une expérimentation de médiation qui détourne et utilise le potentiel créatif de l’objet théâtre et du jeu d’acteur à des fins éducatives et à effets thérapeutiques. Cet article relate à la fois les principes théoriques qui sous-tendent cette activité et leur mise en pratique dans l’espace scénique. Un cas clinique pose la question des effets thérapeutiques de cette activité.

Published: June 2018

Dans un groupe thérapeutique à médiation (pâte à modeler) utilisant les concepts de la psychanalyse, à partir du suivi d’un enfant (8-9 ans), le rôle de l’objet fabriqué dans la relation est analysé. À la fois espace transitionnel et tiers il peut devenir l’objet d’un passage d’une identification projective massive à l’ambivalence. Le média utilisé « en plus » de la parole joue le rôle d’un autre plan de matérialisation du signe comme cela fonctionne dans le principe de l’écriture. La relation d’objet et la construction du sujet s’en trouvent modifiées. Dans ce contexte, l’écriture-art est un outil thérapeutique qui a son efficacité.
Le hip-hop comme expérience esthétique fondamentale : enjeux et mises en perspective
Authors: Weill Benjamine
Published: June 2018

Le hip-hop est un mode de vie, une manière d’agir et de penser et non seulement du divertissement. À ce titre, cette culture fait expérience esthétique puisque dans les pratiques hip-hop chacun apprend à chacun, et chacun expérimente une manière de découvrir de nouveaux points de vue. Par cette expérience, chacun constate qu’il a une action sur le monde, peut s’exprimer et participe de l’humanité. Cela suppose une éducation spécifique et des modalités qui autorisent chacun à créer, rêver, ouvrir son esprit à autrui, la société et son pouvoir d’agir, comme dans le travail social. L’un et l’autre poursuivent le même but : l’émancipation de l’individu.
Une médiation par l’art à l’école : un espace sans élèves ni enseignants
Authors: Augier Pierre
Published: June 2018

De plus en plus d’enfants dans les écoles ne présentent pas ou peu les comportements qu’un enseignant attend de ses élèves. Le nombre grandissant de ces « enfants difficiles » présentant des troubles affectifs nous oblige aujourd’hui à repenser la place qui leur est faite au sein de l’école et non plus à les considérer comme une marge . Notre proposition est ici celle d’un espace permanent de médiation dans un établissement scolaire, s’appuyant sur les outils et processus de symbolisation mobilisés par les arts plastiques. Le cadre de cet atelier thérapeutique ouvre un espace pour se dire, dans un lieu où rien n’est soumis à évaluation et où les voix de l’institution scolaire se taisent, permettant à l’enfant de s’autoriser à jouer et à créer en présence de l’autre, là où les deux étaient proscrits pour l’élève et où l’adulte n’était pas perçu derrière l’enseignant.

Cet entretien présente différentes formes de rencontres créatives proposées à des jeunes dans plusieurs types d’établissements, lycées d’enseignement professionnel, maisons d’enfants à caractère social, institut thérapeutique. Ces ateliers de création constituent une parenthèse dans la vie des institutions. L’artiste qui les anime, souvent en collaboration avec du personnel éducatif, part des thèmes proposés par les jeunes, se met à leur service pour chercher ensemble les moyens techniques de les réaliser. Il n’est donc pas en position de maître ou de technicien, mais témoigne d’un désir de créer et d’arriver à une réalisation en un temps limité. La mise en valeur des œuvres lors d’expositions et de rencontres avec des adultes permet une découverte des possibilités de ces jeunes lors d’échanges avec des professionnels (magistrats, enseignants).
Aristote, père de l’astrophysique scientifique
Authors: Ribas Marie-Noëlle
Published: June 2018

Cet article étudie la manière dont Aristote promeut une méthode d’enquête et de raisonnement originale grâce à laquelle l’astrophysique peut devenir une science au même titre que l’astronomie mathématique. Contre ceux qui croient conférer sa scientificité à l’astronomie en la géométrisant ou en la concevant sur le modèle de la géométrie, Aristote reconsidère la nature de l’astronomie mathématique, son lien à l’astronomie empirique et comment celle-ci doit être distinguée de la physique astronomique comme science indépendante. Parce qu’il montre dans le traité Du ciel comment raisonner correctement en physicien sur les objets supralunaires dont la sensation est problématique, Aristote peut être considéré comme le père de l’astrophysique scientifique.
Compétition, controverses et cultures de microbes : le développement du sérum antipesteux entre Paris et l’Inde (1894-1899)
Authors: Alves Duarte da Silva Matheus
Published: June 2018

La capacité de préparer des sérums et des vaccins capables de guérir ou d’immuniser les êtres humains était affichée par les bactériologistes de la fin du xix e siècle comme l’un des principaux acquis de la « révolution microbienne ». Toutefois, les difficultés rencontrées pour développer un produit thérapeutique allongeaient le chemin conduisant de sa conception à la standardisation et utilisation à grande échelle. Ce décalage est bien illustré par l’analyse de la trajectoire du sérum antipesteux, conçu entre 1894 et 1895 à l’Institut Pasteur. La difficulté majeure ayant ralenti sa standardisation tient à des essais pratiqués en Inde – et non en France – lors des épidémies de peste bubonique de 1897 et 1898. L’analyse des lettres et des cahiers de terrain des deux chercheurs responsables des essais, Alexandre Yersin et Paul Simond, révèle leurs stratégies et les relations qu’ils durent nouer avec les acteurs locaux pour parvenir à leurs fins. Elle dévoile également la compétition et les controverses inévitables ayant opposé Yersin et Simond à d’autres chercheurs européens désireux de tester leurs propres produits en Inde.
Service-Learning: Promoting Empathy Through the Point-in-Time Count of Homeless Populations
Authors: Pierangeli Lori T. , Lenhart Clare M.
Published: June 2018

Background:

An interprofessional service–learning experience, using the U.S. Department of Housing and Urban Development Point-in-Time (PIT) count of unsheltered homeless, was used as the basis of exposing nursing and public health students to those facing homelessness and housing insecurity in their community.

Method:

Learning experiences included pre- and post-PIT count training, PIT count participation, debriefings, online and in-class reflections, and discussion of poverty-related readings. Students unable to participate in the actual count presented nutrition education programs in congregate meal sites.

Results:

Participation in the PIT count received positive student feedback and reflected development of knowledge and empathy of those experiencing homelessness and housing and food insecurity.

Conclusion:

Health professional programs can use the PIT count to expose students to individuals living in poverty, as well as provide meaningful curricular opportunities to foster a culturally competent and empathetic health services work force. [

Interrater Reliability and Usability of a Nurse Anesthesia Clinical Evaluation Instrument
Authors: Schierenbeck Mark W. , Murphy John A.
Published: June 2018

Background:

No Student Registered Nurse Anesthetist (SRNA) clinical evaluation instrument (CEI) has undergone interrater reliability or usability testing, to the authors' knowledge. This project determined the interrater reliability and usability of a new SRNA CEI.

Method:

This was a prospective, mixed qualitative and quantitative, fully crossed observational design with a usability survey. SRNAs' recorded performance during simulation was evaluated by participants, who also completed a usability survey.

Results:

Interrater reliability is high, intraclass correlation coefficient = .982, 95% CI [.884, .960], indicating strong agreement of SRNA clinical performance among participants (
n
= 10). Internal consistency is excellent (Cronbach's α = .943), indicating the CEI is constructed appropriately and participants found it easy to use.

Conclusion:

This CEI may advance the aim of impartiality in the evaluation of SRNA clinical performance through an instrument that is reliable, with good construct, and ease of use. [

Este artículo constituye un breve avance de las investigaciones que, desde hace algunos años, viene efectuando el autor sobre la época tardoantigua en el área de los Pirineos más occidentales. El descubrimiento en tierras alavesas y navarras de dos necrópolis de los siglos VI y VII, con un número de armas digno de mención y con rituales, depósitos y ajuares funerarios que nos remiten no a un contexto cultural hispanovisigodo sino al norte de los Pirineos, permite abrir un debate que replantee las interpretaciones historiográficas actuales para este período.
Los mosaicos como documentos para la Historia de la Hispania Tardia (siglos IV-V)
Authors: Arce Javier
Published: June 2018

El presente artículo examina algunos ejemplos de mosaicos relevantes hallados en contextos arqueológicos de la Hispania tardorromana (IV-V d. C.) e investiga su validez como «fuente para la Historia tardorromana». Recientes investigaciones e interpretaciones han pretendido verlos como una prueba de religiosidad de los propietarios de las villae en las que fueron encontrados. Mi propuesta es que han sido «superinterpretados» y que es necesario ser muy cautos cuando se realizan dichos estudios, teniendo en cuenta el contexto histórico de la producción musiva del periodo tardorromano.

Ánforas itálicas de época tardorromana. Los hallazgos del Palmar Hotel (Premià de Mar, Barcelona)
Authors: Coll i Monteagudo Ramón , Járrega Domínguez Ramón
Published: June 2018

En este trabajo estudiamos un nuevo tipo de ánfora recientemente identificado, perteneciente a la época tardorromana. Estas ánforas probablemente transportaban vino, que era usado para abastecer la ciudad de Roma y eventualmente se comercializaba en otros países del Imperio; al menos, éste es el caso de Hispania, evidenciado por los materiales que aquí estudiamos.

The dispersion behavior of graphene oxide in cement matrix is one important factor in enhancing cement performance. In this work, we investigated the dispersion of graphene oxide in cement by simulating alkaline environment with a solution of calcium hydroxide and studied the corresponding strategy of improving dispersion. The obtained results showed that graphene oxide would flocculate even if calcium hydroxide concentration was very low, which might be the main reason of the unstable properties of the graphene oxide-doped cement. In addition, we discovered that, compared to -OH group, the -COOH group and the long chain of polycarboxylate-based superplasticizer were more effective in delaying the flocculation of graphene oxide. Finally, we proposed a dispersion mechanism of polycarboxylate-based superplasticizer. The study provides inspiration for the design of graphene oxide-doped cement materials.
Kekerasan Kemanusiaan dan Perampasan Tanah Pasca- 1965 di Banyuwangi, Jawa Timur
Authors: Luthfi Ahmad Nashih
Published: June 2018

Kebijakan Land reform di Banyuwangi era 1960-an berhasil meredistribusi tanah kelebihan maksimum, tanah absentee, dan tanah negara bekas perkebunan dan hutan. Pasca kudeta 1965 terjadi kekerasan kemanusiaan dan tindakan counter-Land reform oleh berbagai pihak. Didasarkan pada data-data utama dari kantor pertanahan dan dokumen militer Banyuwangi, artikel ini menunjukkan kaitan erat antara Land reform dengan korban pembunuhan yang menjadi sasaran pasca-1965. Artikel ini adalah usaha awal untuk membuka dimensi ekonomi-politik terhadap massacre pasca-1965. Sejarah agraria dan kekerasan kemanusiaan dalam artikel ini dibaca melalui konsep “primitive accumulation”, dalam argumen bahwa kekerasan kemanusiaan berupa pengusiran, perampasan tanah dan pembunuhan terhadap petani adalah tonggak baru dan bagian integral dari pembangunan politik dan ekonomi agraria Orde Baru berikutnya. Jika massacre adalah making die, pembunuhan dalam arti literal, maka proses yang terjadi setelahnya adalah letting die, berupa tercerabutnya mereka dari sistem produksi (tanah) dan kewarganegaraannya.
Sindhunata: An Indonesian Writer in his Context
Authors: Rae Simon
Published: June 2018

The English translation of two novels by the Indonesian Catholic writer Sindhunata introduces his work to a wider range of readers, for many of whom his very Javanese mode of story-telling will be puzzling. The article introduces the novels, Herding the Wind and The Chinese Princess, both translated in 2015 for the Frankfurt Book Fair, and offers a wider view of Sindhunata’s diverse writing, in the context of his life as a priest, journalist and author. The article is written for those who might appreciate an introduction to an unfamiliar form of story-telling but provides references also for those readers who might wish to follow up other writings in Indonesian.
Utuy Tatang Sontani et l’homme aux yeux de braise
Authors: Chambert-Loir Henri
Published: June 2018

Utuy Tatang Sontani fait partie des écrivains indonésiens qui se trouvaient a l’étranger lorsque les évènements du 30 septembre 1965 provoquèrent un massacre dans les rangs de la gauche indonésienne et bien au-delà. Il ne rentra pas en Indonésie et passa le reste de ses jours en exil, en Chine et en URSS. Durant ses années à Moscou, il rédigea quatre textes autobiographiques, dont l’un est traduit ici. Il dresse le portrait de l’une des plus éminentes figures de l’histoire indonésienne contemporaine. Au-delà de l’image de ce politicien et de la façon dont Utuy présente leurs rapports, l’article examine la tentation du communisme qui ébranla le milieu des intellectuels indonésiens, dans les années 1950 et 60.

Autoimmune regulator (AIRE) deficiency in humans induces a life-threatening generalized autoimmune disease called autoimmune polyendocrinopathy–candidiasis–ectodermal dystrophy (APECED), and no curative treatments are available. Several models of AIRE-deficient mice have been generated, and although they have been useful in understanding the role of AIRE in central tolerance, they do not reproduce accurately the APECED symptoms, and thus there is still a need for an animal model displaying APECED-like disease. We assessed, in this study, the potential of the rat as an accurate model for APECED. In this study, we demonstrate that in rat, AIRE is expressed by MHC class II (MCH-II)+ and MHC-II− medullary thymic epithelial cells in thymus and by CD4int conventional dendritic cells in periphery. To our knowledge, we generated the first AIRE-deficient rat model using zinc-finger nucleases and demonstrated that they display several of the key symptoms of APECED disease, including alopecia, skin depigmentation, and nail dystrophy, independently of the genetic background. We observed severe autoimmune lesions in a large spectrum of organs, in particular in the pancreas, and identified several autoantibodies in organs and cytokines such as type I IFNs and IL-17 at levels similar to APECED. Finally, we demonstrated a biased Ab response to IgG1, IgM, and IgA isotypes. Altogether, our data demonstrate that AIRE-deficient rat is a relevant APECED animal model, opening new opportunity to test curative therapeutic treatments.

Introduction: South Africa is moving towards achieving elimination of mother-to-child transmission (eMTCT) but gaps remain in eMTCT programmes. Documenting successful outcomes of health systems interventions to address these gaps could encourage similar initiatives in the future.Methods: We describe the effectiveness of a Quality Improvement Project (QIP) to improve HIV retesting rates during pregnancy among women who had previously tested negative by redesigning the clinic process. Eight poorly-performing clinics were selected and compared with eight better-performing control clinics in a subdistrict in North West Province. Over nine months, root cause analysis and testing of change ideas using Plan-Do-Study-Act cycles were used to identify and refine interventions. Analysis of patient flow showed that women were referred for retesting following their nurse-driven antenatal visits, and many left without retesting as this would have further prolonged their visit. Processes were redesigned and standardised, where a counsellor was charged with retesting patients before antenatal consults. Staff were mentored on data collection and interpretation process. Quality improvement nurse advisors monitored indicators bi-weekly and adjusted interventions accordingly.Results: Retesting in intervention clinics rose from 36% in the three months pre-intervention to full coverage at month nine. At the end of the study, retesting in intervention clinics was 20% higher than in controls. Retesting also increased in the subdistrict overall.Conclusion: Service coverage and overall impact of HIV programmes can be raised through care-process analysis that optimises patient flow, supported by targeted QI interventions. These QI methodologies may be effective elsewhere for identifying new HIV infections in pregnant/breastfeeding women, and possibly in other services.
Implementing emergency department-based HIV testing in a low-resource setting: The value of a structured feasibility assessment tool

Published: June 2018

Introduction: HIV is a worldwide health problem with continuing high rates of new infections in many parts of the world. This lack of progress in decreasing overall incidence rates has sparked innovative HIV testing strategies, including expansion of testing into the emergency department (ED) setting. Emergency departments have been shown to be high-yield testing venues in the United States and other developed world settings. The feasibility of expanding public health HIV services in the ED in limited-resource countries is unclear.Methods: We performed a cross-sectional feasibility assessment of a convenience sample of four hospitals in the Eastern Cape, South Africa. We administered three adapted interview tools from a previously field-tested survey instrument at each facility (total of 10 interviews) to gather an overview of the health facility, their HIV counselling and testing services, and their laboratory services.Results: All of the health facilities had access to basic commodities such as water and electricity. Many had severe human resource limitations and provided care to wide population catchment areas. In addition, there was little integration of HIV testing into current daily ED operations. Hospital staff identified numerous barriers to future ED testing efforts.Conclusions: Although control of the HIV epidemic requires innovative testing strategies and treatment, specific assessments are warranted on how to incorporate routine HIV testing into an acute care facility like the ED, which typically has many competing priorities. The use of a prospective structured tool incorporating both barriers and benefits can provide valuable field-tested guidance for increased programme planning for HIV testing.
Potencial para la exploración de aguas subterráneas en la Demarcación Hidrográfica Puyango Catamayo, Ecuador, utilizando un proceso de análisis jerárquico basado en SIG y teledetección

The objective of this study is to apply geographic information systems and remote sensing techniques to map potential areas for groundwater exploration in the Puyango Catamayo hydrographic demarcation, based on free input data. The research’s primary data are a digital elevation model, satellite images, regional geology and rainfall. From the methodological point of view, Multi-Criteria Decision Analysis is applied, using an Analytic Hierarchy Process, which takes as thematic layers the  rock permeability, the rainfall, the drainage density,  the terrain slope, and the normalized difference vegetation index. Thus,  the Groundwater Potential Index is obtained, which is used to map potential areas for groundwater exploration. The resulting map is compared with the existing data of the water point inventory, generated by the Ecuador’s National Institute of Meteorology and Hydrology. Data validation by this method shows that 30% of the water points are located in areas not suitable for groundwater exploration, while 70% are in favorable areas.
Combination of satellite imagery with meteorological data for estimating reference evapotranspiration
Authors: Montero D. , Echeverry F. , Hernández F.
Published: June 2018

The Food and Agriculture Organization of the United Nations (FAO) in its publication No. 56 of the Irrigation and Drainage Series presents the FAO Penman-Monteith procedure for the estimation of reference evapotranspiration from meteorological data, however, its calculation may be complicated in areas where there are no weather stations. This paper presents an evaluation of the potential of the Land Surface Temperature and Digital Elevation Models products derived from the MODIS and ASTER sensors, both on board the Terra EOS AM-1 satellite, for the estimation of reference evapotranspiration using the Penman-Monteith FAO-56, Hargreaves, Thornthwaite and Blaney-Criddle models. The four models were compared with the method proposed by FAO calculated with the observed data of a ground based meteorological station, finding a significant relation with the models Penman-Monteith FAO-56 and Hargreaves.
