Published: April 2018

Detection of cholesterol crystals (Chcs) in atherosclerosis disease is important for understanding the pathophysiology of atherosclerosis. Polarization microscopy (PM) has been in use traditionally for detecting Chcs, but they have difficulty in distinguishing Chcs with other crystalline materials in tissue, such as collagens. Thus, most studies using PM have been limited to studying cell-level samples. Although various methods have been proposed to detect Chcs with high specificity, most of them have low signal-to-noise ratios, a high system construction cost, and are difficult to operate due to a complex protocol. To address these problems, we have developed a simple and inexpensive universal serial bus (USB) PM system equipped with a 5700 K cool-white light-emitting diode (LED). In this system, Chcs are shown in a light blue color while collagen is shown in a yellow color. More importantly, the contrast between Chcs and collagens is improved by a factor of 2.3 under an aqueous condition in these PM images. These imaging results are well-matched with the ones acquired with two-photon microscopy (TPM). The system can visualize the features of atherosclerosis that cannot be visualized by the conventional hematoxylin and eosin and oil-red-o staining methods. Thus, we believe that this simple USB PM system can be widely used to identify Chcs in atherosclerosis.

Published: April 2018

The neotropical agroecosystems are important areas in the global scene in terms of livestock production. Therefore, a good conservation of their soils is crucial in order to both guarantee food safety and reduce the impact of land degradation processes. Conservation of neotropical soils used for farming activities could be obtained using veterinary medicine and adopting new grazing systems in the last decades. A wide bibliographical review was carried out which illustrates current issues in neotropical agroecosystems, the importance of their soil properties highlighting the role played by dung beetles within the edaphofauna, and the effects of the most common anti-parasitic practices as well as some natural alternatives. Finally, we present commonly adopted grazing systems and how they are affecting soil properties and animal welfare. The conversion of forest into agricultural and pasture land is altering the biochemical quality of soils. Furthermore, the use of ivermectin is dangerously reducing the total amount of dung beetles that are a key element in nutrient recycling processes. The implementation of new grazing systems (e.g., Voisin, Savory) is progressively fragmenting the habitat of many species. Nevertheless, there are also some benefits in this kind of practices and some natural alternatives to anthelmintics are being tested.

Published: April 2018

With the establishment of the Belt and Road national strategy, Quanzhou Port is a significant development opportunity. Quanzhou Port is the origin of the 21st century Maritime Silk Road and part of the Belt and Road, but as a pioneer project of the Maritime Silk Road and the main port in the Belt and Road strategy, its development has encountered some challenges and problems. Hence, this paper aims to evaluate the competitiveness of Quanzhou Port based on the criteria selected by experts and corresponding improvement suggestions are put forward for its weaknesses. Using fuzzy-AHP and ELECTRE III, port competitiveness is evaluated according to the total weights obtained based on the different criteria used. The key criteria consist of six factors (port size, port location, hinterland economy, port costs, operations management and growth potential) that are divided into 18 sub-criteria. Five competing ports were selected with respect to geographical proximity. The order of ranking according to ELECTRE III are as follows: Kaohsiung Port, Xiamen Port, Fuzhou Port, Taichug Port and Quanzhou Port. The findings show that the port of Quanzhou appears last in the ordering sequence, resulting in a need for integrative approaches to promote its competitiveness. Compared with competitive ports, Quanzhou Port has relatively weak overall infrastructure and relatively high port costs, which leads to a lack of obvious flow of port materials and a decrease in professional unloading services. Particularly in hinterland port economies, the industrial structure is extensive and backward. Hence, the question of how to achieve a green transformation of the manufacturing industry will be important for Quanzhou Port. This paper points out directions for the future development of Quanzhou Port and applies comprehensive evaluation methods, namely fuzzy-AHP and ELECTRE III.
A Systems Analysis of Factors Influencing Household Solar PV Adoption in Santiago, Chile
Authors: Walters Jeffrey , Kaminsky Jessica , Gottschamer Lawrence
Published: April 2018

Societal uptake of household solar photovoltaic (PV) technology is the result of a complex and interdependent array of technical, social, political and economic factors. This novel study employs a systems lens to examine both technical and non-technical barriers to renewables, with a focus on interactions that are empirically influential on PV uptake. Using local solar expert stakeholder input into a participatory systems approach, this study provides a structural analysis of factors influencing household solar adoption. The approach is applied and assessed for household solar PV systems in Santiago, Chile, to gain insight into the interconnected factors driving technology adoption. Barriers and motivations to adoption identified in a recent Delphi study for Santiago were used to create a list of factors thought by local experts to impact future adoption. These factors and their pairwise interactions were modeled using the impact matrix multiplication applied to classification (MICMAC) technique and analyzed within a four-hour workshop with eight solar experts in Santiago. Results from the analysis regarding factor influence, dependence and evolutionary trajectories were presented to experts and discussed at length. Salient discussion points focused on the need for attractive financial incentives, knowledge diffusion among potential consumers, and a maturing market that incites a cultural shift towards customers who desire energy independence. Intuitive and insightful programmatic areas were illuminated for policy and action in Santiago based on a systems-focused interpretation of factors in the form of short- and long-term strategies.

Published: April 2018

Fog computing has become the revolutionary paradigm and one of the intelligent services of the 5th Generation (5G) emerging network, while Internet of Things (IoT) lies under its main umbrella. Enhancing and optimizing the quality of service (QoS) in Fog computing networks is one of the critical challenges of the present. In the meantime, strong links between the Fog, IoT devices and the supporting back-end servers is done through large scale cloud data centers and with the linear exponential trend of IoT devices and voluminous generated data. Fog computing is one of the vital and potential solutions for IoT in close connection with things and end users with less latency but due to high computational complexity, less storage capacity and more power drain in the cloud it is inappropriate choice. So, to remedy this issue, we propose transmission power control (TPC) based QoS optimization algorithm named (QoS-TPC) in the Fog computing. Besides, we propose the Fog-IoT-TPC-QoS architecture and establish the connection between TPC and Fog computing by considering static and dynamic conditions of wireless channel. Experimental results examine that proposed QoS-TPC optimizes the QoS in terms of maximum throughput, less delay, less jitter and minimum energy drain as compared to the conventional that is, ATPC, SKims and constant TPC methods.
Cosmetic Detection Framework for Face and Iris Biometrics
Authors: Sharifi Omid , Eskandari Maryam
Published: April 2018

Cosmetics pose challenges to the recognition performance of face and iris biometric systems due to its ability to alter natural facial and iris patterns. Facial makeup and iris contact lens are considered to be commonly applied cosmetics for the face and iris in this study. The present work aims to present a novel solution for the detection of cosmetics in both face and iris biometrics by the fusion of texture, shape and color descriptors of images. The proposed cosmetic detection scheme combines the microtexton information from the local primitives of texture descriptors with the color spaces achieved from overlapped blocks in order to achieve better detection of spots, flat areas, edges, edge ends, curves, appearance and colors. The proposed cosmetic detection scheme was applied to the YMU YouTube makeup database (YMD) facial makeup database and IIIT-Delhi Contact Lens iris database. The results demonstrate that the proposed cosmetic detection scheme is significantly improved compared to the other schemes implemented in this study.
Visual Non-Instrumental On-Site Detection of Fumonisin B1, B2, and B3 in Cereal Samples Using a Clean-Up Combined with Gel-Based Immunoaffinity Test Column Assay
Authors: Sheng Wei , Wu Hesen , Ji Weihong , Li Zhi , Chu Fangyu , Wang Shuo
Published: April 2018

A visual immunoaffinity test column (IATC) assay was developed to detect fumonisins in cereal samples for spot tests without the need for special instruments. The developed IATC assay had equivalent recognition capability for fumonisin B1 (FB1), fumonisin B2 (FB2), or fumonisin B3 (FB3), and exhibited no cross-reactivity with aflatoxin B1, ochratoxin A, zearalenone, or the T-2 toxin. The sample pretreatment was accomplished more rapidly and with greater ease, the entire assay procedure was completed in approximately 10 min, including sample pretreatment and testing. The limits of detection (LODs) of the IATC assay to detect fumonisins in the maize, barley, oat, and millet samples were 20 μg kg−1. The results of the spiked maize, barley, oat, and millet and real maize samples by the IATC assay agreed well with the results obtained by the commercial fumonisin enzyme-linked immunosorbent assay (ELISA) test kit and liquid chromatography-tandem mass spectrometry (LC-MS/MS), respectively. The developed IATC assay can serve as a useful screening tool for the rapid, qualitative, and semi-quantitative detection of the total content of fumonisins (sum of FB1, FB2, and FB3) in cereal samples on-site.
Reflection Phenomena in Underground Pumped Storage Reservoirs
Authors: Pummer Elena , Schüttrumpf Holger
Published: April 2018

Energy storage through hydropower leads to free surface water waves in the connected reservoirs. The reason for this is the movement of water between reservoirs at different elevations, which is necessary for electrical energy storage. Currently, the expansion of renewable energies requires the development of fast and flexible energy storage systems, of which classical pumped storage plants are the only technically proven and cost-effective technology and are the most used. Instead of classical pumped storage plants, where reservoirs are located on the surface, underground pumped storage plants with subsurface reservoirs could be an alternative. They are independent of topography and have a low surface area requirement. This can be a great advantage for energy storage expansion in case of environmental issues, residents’ concerns and an unusable terrain surface. However, the reservoirs of underground pumped storage plants differ in design from classical ones for stability and space reasons. The hydraulic design is essential to ensure their satisfactory hydraulic performance. The paper presents a hybrid model study, which is defined here as a combination of physical and numerical modelling to use the advantages and to compensate for the disadvantages of the respective methods. It shows the analysis of waves in ventilated underground reservoir systems with a great length to height ratio, considering new operational aspects from energy supply systems with a great percentage of renewable energies. The multifaceted and narrow design of the reservoirs leads to complex free surface flows; for example, undular and breaking bores arise. The results show excessive wave heights through wave reflections, caused by the impermeable reservoir boundaries. Hence, their knowledge is essential for a successful operational and constructive design of the reservoirs.
Water Poverty in Rural Communities of Arid Areas in China
Authors: Liu Wenxin , Zhao Minjuan , Xu Tao
Published: April 2018

For developing countries, an adequate domestic water supply is conventionally assessed based on the proportion of communities that are covered by improved water sources. However, it is difficult to evaluate water poverty accurately, as it is multidimensional. For this reason, this paper used the Water Poverty Index (WPI) to measure water poverty in rural communities of arid areas in China. This study also uses the Least Square Error (LSE) model to analyze the influencing factors of water poverty. Based on the WPI and LSE, the results showed that the rural communities of Sheshu, Fanyao, Dongcao, Qiaodi, and Gouershang (listed in order of priority of need for intervention) are in a water poverty situation. In rural communities with high water poverty, the suggested priority order for the study was environment, capacity, use, resources, and access, with the environmental factor needing to be improved. The results are useful for prioritizing areas and identifying the extent of the need for policy intervention on different scales. The research findings are intended to complement the evaluation of water poverty and to provide a strategy for regional water resources management to relieve water poverty.
ZBTB7/miR-137 Autoregulatory Circuit Promotes the Progression of Renal Carcinoma
Authors: Wang Lihui , Li Qi , Ye Zhuo , Qiao Baoping
Published: April 2018

Renal carcinoma greatly threatens human health, but the involved molecular mechanisms are far from complete understanding. As a master oncogene driving the initiation of many other cancers, ZBTB7 has not been established to be associated with renal cancer. Our data revealed that ZBTB7
is highly expressed in renal carcinoma specimens and cell lines, compared with normal cells. The silencing of ZBTB7 suppressed the proliferation and invasion of renal cancer cells. ZBTB7 overexpression rendered normal cells with higher proliferation rates and invasiveness. An animal study
further confirmed the role of ZBTB7 in the growth of renal carcinoma. Moreover, miR-137 was identified to negatively regulate the expression of ZBTB7, and its abundance is inversely correlated with that of ZBTB7 in renal carcinoma specimens and cell lines. ZBTB7 overexpression may be induced
by miR-137 downregulation. Interestingly, ZBTB7 can also suppress miR-137 expression by binding to its recognition site within the miR-137 promoter region. Taken together, we identified an autoregulatory loop consisting of ZBTB7 and miR-137 in gastric cancers, and targeting this pathway may
be an effective strategy for renal carcinoma cancer therapy.

We present a catalog of extended low surface brightness galaxies (LSBGs) identified in the Wide layer of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). Using the first ∼200 deg2 of the survey, we have uncovered 781 LSBGs, spanning red (g − i ≥ 0.64) and blue (g − i < 0.64) colors and a wide range of morphologies. Since we focus on extended galaxies (r
eff = 2.″5–14″), our sample is likely dominated by low-redshift objects. We define LSBGs to have mean surface brightnesses

mag arcsec−2, which allows nucleated galaxies into our sample. As a result, the central surface brightness distribution spans a wide range of μ
0(g) = 18–27.4 mag arcsec−2, with 50% and 95% of galaxies fainter than 24.3 and 22 mag arcsec−2, respectively. Furthermore, the surface brightness distribution is a strong function of color, with the red distribution being much broader and generally fainter than that of the blue LSBGs, and this trend shows a clear correlation with galaxy morphology. Red LSBGs typically have smooth light profiles that are well characterized by single-component Sérsic functions. In contrast, blue LSBGs tend to have irregular morphologies and show evidence for ongoing star formation. We cross-match our sample with existing optical, H i, and ultraviolet catalogs to gain insight into the physical nature of the LSBGs. We find that our sample is diverse, ranging from dwarf spheroidals and ultradiffuse galaxies in nearby groups to gas-rich irregulars to giant LSB spirals, demonstrating the potential of the HSC-SSP to provide a truly unprecedented view of the LSBG population.

Combining the Mars Atmosphere and Volatile Evolution measurements of neutral atmospheric density, solar EUV/X-ray flux, and differential photoelectron intensity made during 240 nominal orbits, we calculate the ionization efficiency, defined as the ratio of the secondary (photoelectron impact) ionization rate to the primary (photon impact) ionization rate, in the dayside Martian upper atmosphere under a range of solar illumination conditions. Both the CO2 and O ionization efficiencies tend to be constant from 160 km up to 250 km, with respective median values of 0.19 ± 0.03 and 0.27 ± 0.04. These values are useful for fast calculation of the ionization rate in the dayside Martian upper atmosphere, without the need to construct photoelectron transport models. No substantial diurnal and solar cycle variations can be identified, except for a marginal trend of reduced ionization efficiency approaching the terminator. These observations are favorably interpreted by a simple scenario with ionization efficiencies, as a first approximation, determined by a comparison between relevant cross sections. Our analysis further reveals a connection between regions with strong crustal magnetic fields and regions with high ionization efficiencies, which are likely indicative of more efficient vertical transport of photoelectrons near magnetic anomalies.

Le Revenu d’existence, une réforme triple : impôt, cotisations, prestations
Authors: de Basquiat Marc
Published: April 2018

Résumé Un Revenu d’existence de 480 euros par mois est théoriquement réalisable fin 2017 en reconfigurant des mécanismes existants et sans mobiliser de budget additionnel significatif. Il s’agit d’abord de simplifier l’impôt sur le revenu actuel en supprimant la tranche 2, en transformant la tranche 3 en imposition de base mensuelle, en considérant les tranches 4 et suivantes comme une surtaxe annuelle et en remplaçant le quotient conjugal et le quotient familial par des abattements forfaitaires individuels. La combinaison des cotisations sociales non contributives et de la réduction Fillon contribue aussi à la redistribution, au même titre que le RSA et la Prime d’activité. La fusion de tous ces mécanismes, de natures diverses, permet d’instaurer un mécanisme fiscal universel où tous les ménages sont traités selon les mêmes règles de calcul simples, automatiques, sans stigmatisation. Les principaux ajustements concernent la prise en compte des couples. D’autres ajustements secondaires sont nécessaires, qui dépassent le cadre limité de cet article.
Le marché français de capacité d’électricité

Published: April 2018

Annoncé dès 2010 pour garantir la sécurité d’approvisionnement lors des pointes de demande, le marché français de capacité d’électricité n’a été mis en place qu’en janvier 2017. Ce délai ne s’explique pas seulement par la complexité de la discussion quant à la nécessité d’adjoindre des incitations additionnelles aux signaux de prix fournis par les marchés de gros de l’électricité et des modalités optimales d’organisation des mécanismes de capacité, il trouve également ses origines dans la difficulté à faire émerger une solution acceptable pour les différentes parties prenantes du marché français de l’électricité mais surtout compatible avec les exigences de la Commission européenne, qu’il s’agisse des règles de concurrence ou de la politique énergétique. Cet article analyse la construction d’un compromis entre objectifs énergétiques et contraintes concurrentielles.

Resident-to-resident elder mistreatment (R-REM) occurs frequently in long-term services and support settings. The purpose of the current study was to evaluate the effect of a R-REM training program for nursing and other front-line staff on resident falls and injuries in a cluster randomized trial of units within four nursing homes. Interview and observational data from a sample of 1,201 residents (
n
= 600 and
n
= 601 in the usual care and intervention groups, respectively) and staff were collected at baseline and 6 and 12 months. A generalized linear model was used to model the falls/injuries outcome. The net reduction in falls and injuries was 5%, translating to 10 saved events per year in an averagesized facility. Although the result did not reach statistical significance due to low power, the findings of fall prevention associated with implementing the intervention in long-term care facilities is clinically important.

Un carrefour routier au cœur du Jura méridional (Bugey, Ain) du ve au xviiie siècle : morphologie, modelés et itinéraires
Authors: Mélo Alain
Published: April 2018

L'analyse morphologique du réseau des voies de communication dans une petite plaine centrale du Jura méridional (Bugey, Ain) a mis en évidence une réorientation des circulations principales à travers ces montagnes. Des voies orientées sud-nord drainaient les flux d'une part entre Lyon et le haut Jura, route utilisée par les ermites et les moines de Saint-Claude aux ve et vie siècles, et d'autre part entre Belley et Lons-le-Saunier, voie par où transita la dépouille du roi Charles le Chauve en 877, entre le col du Mont-Cenis (Savoie) et Saint-Denis-en-France. Dès le xive siècle les circulations, essentiellement marchandes, se réorientent est-ouest avec le développement d'abord des foires de Genève (à l'est) puis de celles de Lyon (à l'ouest) dans la seconde moitié du xve siècle. Cette orientation des flux majeurs s'est perpétuée jusqu'à aujourd'hui avec la création d'un solide réseau local de routes royales dès 1740.
Une maison d’époque mamelouke (xve- xvie siècles) à Damas (Syrie) et son évolution
Authors: Fayyad Imane
Published: April 2018

La maison, objet de cette étude, est située à l’intérieur de la muraille de Damas. Cette maison habitée jusqu’à 2011, mais en mauvais état, n’a jamais été étudiée. Elle possède un grand nombre de vestiges remarquables. Elle s’étend sur deux étages et sur une surface de 242,9 m. Elle offre une particularité : son rez-de-chaussée est situé à 2,18 m au-dessous du niveau de la ruelle, indice d’ancienneté de cette demeure peu remaniée. Son intérêt archéologique provient des vestiges de sa qāʻa nord, de son īwān, et de l’accès par un passage non coudé vers la cour intérieure. Son sol, en cours de déblaiement apportera sans doute d’autres informations. Aucune inscription ne permet de la dater précisément. L’objet de ce travail est donc de montrer qu’il s’agit d’une maison remontant probablement à l’époque mamelouke. Pour ce faire on procédera à une analyse complète de ses éléments architecturaux et décoratifs et on tentera de la situer par rapport à d’autres maisons datées précisément.
L’armement dans les tombes de guerriers de la nécropole mérovingienne d’Erstein (Bas-Rhin)
Authors: Fischbach Thomas
Published: April 2018

La nécropole d’Erstein (Bas-Rhin) est, à ce jour, la plus vaste découverte en Alsace, avec 248 sépultures, mais également l’une des plus remarquables, notamment par l’abondant mobilier qui y a été découvert. Dans le cadre d’un Master soutenu en 2010, l’armement et les statuts sociaux des tombes de guerriers ont été étudiés, et publier les données recueillies lors de ce travail semblait indispensable. Les datations obtenues par l’étude typologique des armes s’échelonnent entre la fin du Ve et le début du VIIe siècle, mais on observe une très forte concentration durant les deux derniers tiers du VIe siècle (phases MA2 à MA3). Les proportions des différents types d’armes plaident plutôt en faveur d’influences alamanes ou thuringiennes, mais ces dernières ne pourront être confirmées que par une étude complète du site. En outre, on observe un groupe de sépultures de guerriers pouvant être considérées comme privilégiées, conférant au site d’Erstein un statut particulier au VIe siècle, qui devra, lui aussi, être étudié en profondeur.
Un nouveau bâtiment du cloître de Saint-Hilaire-le-Grand à Poitiers (xe-xive siècle)
Authors: Barbier Emmanuel , Jégouzo Anne
Published: April 2018

L’opération d’archéologie préventive réalisée dans le cloître de Saint-Hilaire-le-Grand à Poitiers a permis d’étudier un bâtiment inédit en limite sud de la collégiale. Sur une superficie de 170 m² et deux niveaux particulièrement bien conservés, il se révèle un témoin privilégié de l’évolution architecturale et topographique du cloître. Fondé sur des soubassements du bas empire, cet ensemble bâti connaît cinq grandes phases de constructions jusqu’aux remaniements du XIXe siècle. La première grande campagne de travaux correspond à l’édification autour du Xe siècle d’une clôture monumentale séparant un espace consacré d’un espace civil. L’emplacement comme les dimensions hors norme de cette maçonnerie évoque la possibilité de claustrum ou castrum… Au XIe siècle, un vaste cellier est aménagé contre cette limite, entraînant des modifications importantes dans la circulation et l’organisation du cloître. L’ensemble est considérablement remanié à partit du XIIIe siècle avec l’ouverture de nouveaux accès, une partition de l’espace interne et l’aménagement d’un plancher toujours conservé.
Les ardoises gravées de l’abbaye de Prémontré (Aisne), un support de notation musicale aux xve-xvie siècles
Authors: Galmiche Thierry , Buccio Vincent
Published: April 2018

L’abbaye de Prémontré a été fondée en 1121 dans l’évêché de Laon. Trois ardoises gravées de notations musicales ont été mises au jour lors de fouilles archéologiques réalisées dans l’enceinte abbatiale entre 2010 et 2012. Pour deux d’entre elles, ces inscriptions consistent uniquement en des portées. Pour l’autre ardoise, des notes de musique ont, en outre, été dessinées.Un premier recensement indique que ce type d’artefact n’est pas isolé, trente-trois objets similaires ont en effet été dénombrés. Ils sont tous datés des xve-xve siècle. Dans l’état actuel des recherches, l’aire géographique de ces découvertes s’étend du sud-ouest de la France aux îles Britanniques en passant par la Bretagne, l’Île-de-France, la Picardie, la Belgique et les Pays-Bas.L’essentiel de ces ardoises ont été retrouvées en contexte ecclésiastique. Leur examen fait ressortir des disparités tant au niveau de la forme des ardoises que des dimensions, parfois difficiles à apprécier, et des inscriptions qui y sont portées. A minima, des portées sont présentes (à l’exception de l’exemplaire de la chapelle de Lopikerkapel, les notes sont en notation blanche mesurée). Dans d’autres cas, l’intention de réaliser des supports destinés à être réutilisés est patente.Ces différences nous ont conduits à définir trois catégories d’ardoise. Les premières, sur lesquelles sont inscrites des portées et, de façon occasionnelle des notes, ont été utilisées comme simple support à noter de la musique. Après chaque usage, elles sont effacées. Ces supports ont ainsi pu servir pour l’apprentissage de la composition ou pour l’entraînement à la concordance des voix. Les ardoises 2 et 3 de Prémontré ont été rangées dans ce groupe. Des extraits musicaux sont intentionnellement gravés sur les schistes de la deuxième catégorie mais leur usage est unique. L’emploi de ces ardoises comme support temporaire de composition peut être proposé. Une fois l’extrait recopié, l’ardoise est jetée. La troisième catégorie, numériquement moins importante, est constituée d’ardoises à usages répétés. Ces schistes pourraient avoir été utilisés dans l’apprentissage par mémorisation ou comme supports pour des choristes. L’exemplaire 1 de Prémontré, classé dans cette catégorie, est le plus complet : il est exceptionnel par son état de conservation et par la longueur du fragment musical gravé. Chacune de ces ardoises pourrait donc avoir été utilisée dans la composition ou l’apprentissage de la musique.

Authors: Bouëtiez Emmanuelle du , Dufour Jean-Yves
Published: April 2018

Plus de 1400 éléments de pavement en terre cuite ont été mis au jour sous la cour du Grand Commun du château de Versailles. Ils proviennent principalement du jeu de paume construit pour Louis XIII et de la maison du paumier. Leur intérêt réside non seulement dans leur calage chronologique bien affirmé – une cinquantaine d’années – mais également dans la présence de séries numériquement importantes permettant de nombreuses observations sur leur mode de fabrication. Souvent trouvés à l’état de débris, ces carreaux non décorés, d’une grande simplicité et peu attrayants ne sont que rarement étudiés. Cet article pose les premiers jalons dans la constitution d’un corpus francilien.
#Lancerhealth: Using Twitter and Instagram as a Tool in a Campus Wide Health Promotion Initiative
Authors: Santarossa Sara , Woodruff Sarah J.
Published: April 2018

The present study aimed to explore using popular technology that people already have/use as a health promotion tool, in a campus wide social media health promotion initiative, entitled #LancerHealth. During a two-week period the university community was asked to share photos on Twitter and Instagram of What does being healthy on campus look like to you?, while tagging the image with #LancerHealth. All publically tagged media was collected using the Netlytic software and analysed. Text analysis (N=234 records, Twitter; N=141 records, Instagram) revealed that the majority of the conversation was positive and focused on health and the university. Social network analysis, based on five network properties, showed a small network with little interaction. Lastly, photo coding analysis (N=71 unique image) indicated that the majority of the shared images were of physical activity (52%) and on campus (80%). Further research into this area is warranted.

Published: April 2018

The study investigated the influence of classroom interaction patterns on achievement in biology among Senior Secondary School Students in Anambra State. One research question and one null hypothesis tested at 0.05 level of significance guided the study. A causal comparative or (expost-facto) design was used; a population of 10, 206 SSII Biology students in government owned Secondary Schools in three education zones namely; Awka, Nnewi and Onitsha of Anambra State. The sample consisted of 265 SSII biology students (141 males and 124 girls) drawn from 10,206 biology students. Purposive and random sampling technique was used for the study. Six (6) single sex schools (2 males, 2 females and 2, co-educational) were purposively sampled from the three education zones. Two instruments were employed for data collection namely: Biology Achievement Test (BAT) constructed by the researchers and an adapted questionnaire titled “Previous Classroom Interaction Categorization Test (PCICT) designed to evaluate the level of participation of the teachers compared with  students for each pattern of interaction in their precious biology classroom activities. BAT and PCICT were validated by two biology educators and two expert in measurement and evaluation all from Science Education Department, University of Nigeria Nsukka. BAT reliability coefficient was established using Kuder-Richardson 20 (K-R2O) method which gave 0.86 and PCICT reliability was established using Pearson Product Moment Correlation coefficient which gave an index of 0.80. Data were analyzed using mean, and standard deviation to answer the research questions while one-way Analysis of Variance (ANOVA) was used to test the null hypothesis. Result showed among others that classroom interaction patterns significantly influenced students’ achievement in biology. Recommendations and conclusion were highlighted.Keywords: Classroom interaction patterns, Achievement, Biology, Students
El último urbanismo de Antonio Bonet: el poblado SOS (1970)
Authors: Ródenas García Juan Fernando
Published: April 2018

The SOS Children’s Village at Sant Feliu de Codines in Barcelona (1970), the Hifrensa village (completed), and the Prat I and II urban development plans (not completed) were the final major urban complexes designed by Antonio Bonet (not counting his projects for the tourist sector). At SOS, Bonet designed a residential ensemble for orphaned children comprising communal educational and sporting facilities, by recreating, on a human scale, the atmosphere of the villages depicted in the photographs published in issue 18 (1935) of the GATEPAC magazine AC Documentos de Actividad Contemporánea, which was dedicated to popular architecture. Whitewashed pavilions, vaults, porches, patios, walls and stone platforms arranged like agricultural terraces were the features by which he constructed the landscape of a modern village but with old-fashioned forms. In this paper we analyse this unprecedented work, which, although it was never constructed, expresses the architect’s singular interpretation of the countryside and habitability conditions for orphans. Moreover, this work concentrates the architect’s experience as an experienced urbanist who in the 1970s challenged his fundamental theoretical creed, the Athens Charter, from a historical perspective.
Meaghan Morris: Cultural Historian
Authors: Healy Chris
Published: April 2018

Meaghan Morris was celebrated at the Meaghan Morris Festival as a mentor, a cultural theorist, a much-loved colleague, a lecturer, a polemicist and a stirrer, a teacher, an internationalist, a translator and much else besides. Here, I want to add to that chorus by making a very specific case: that Meaghan Morris is the most significant and innovative living Australian cultural historian. This characterisation is, in part, rooted in my own investments in work at the intersections of cultural studies and cultural history but it is of much greater significance. An influential contemporary characterisation of cultural studies is that it was a boomer reaction to existing disciplinary constraints, a manifestation of anti-canonical impulses that choose instead to celebrate marginality while at the same time making an innovative case for the ways in which culture matters. It follows that if, today, academic disciplines in the social sciences and humanities have become highly flexible (rather than canonical) and maintained their institutional hegemony while simultaneously becoming irrelevant to much knowledge-work and that, today, margins and mainstreams seem like next-to-useless terms to describe cultural topographies or flows and that, today, culture matters nowhere so much as the rapacious industries of media cultures, then perhaps the moment of cultural studies seems of historical interest only.1

My keyword today is action. No, it’s not about Meaghan Morris the action hero! But it is about Meaghan Morris as a woman of action. It is also about Meaghan’s work on action cinema and cultural research as engaged scholarship in action.
Characterization of organic nitrate constituents of secondary organic aerosol (SOA) from nitrate-radical-initiated oxidation of limonene using high-resolution chemical ionization mass spectrometry

Published: April 2018

Abstract. The gas-phase nitrate radical (NO3⚫) initiated oxidation of limonene can produce organic nitrate species with varying physical properties. Low-volatility products can contribute to secondary organic aerosol (SOA) formation and organic nitrates may serve as a NOx reservoir, which could be especially important in regions with high biogenic emissions. This work presents the measurement results from flow reactor studies on the reaction of NO3⚫ with limonene using a High-Resolution Time-of-Flight Chemical Ionization Mass Spectrometer (HR-ToF-CIMS) combined with a Filter Inlet for Gases and AEROsols (FIGAERO). Major condensed-phase species were compared to those in the Master Chemical Mechanism (MCM) limonene mechanism, and many non-listed species were identified. The volatility properties of the most prevalent organic nitrates in the produced SOA were determined. Analysis of multiple experiments resulted in the identification of several dominant species (including C10H15NO6, C10H17NO6, C8H11NO6, C10H17NO7, and C9H13NO7) that occurred in the SOA under all conditions considered. Additionally, the formation of dimers was consistently observed and these species resided almost completely in the particle phase. The identities of these species are discussed, and formation mechanisms are proposed. Cluster analysis of the desorption temperatures corresponding to the analyzed particle-phase species yielded at least five distinct groupings based on a combination of molecular weight and desorption profile. Overall, the results indicate that the oxidation of limonene by NO3⚫ produces a complex mixture of highly oxygenated monomer and dimer products that contribute to SOA formation.
Analytical flow duration curves for summer streamflow in Switzerland
Authors: Santos Ana Clara , Portela Maria Manuela , Rinaldo Andrea , Schaefli Bettina
Published: April 2018

Abstract. This paper proposes a systematic assessment of the performance
of an analytical modeling framework for streamflow probability distributions
for a set of 25 Swiss catchments. These catchments show a wide range of
hydroclimatic regimes, including namely snow-influenced streamflows. The
model parameters are calculated from a spatially averaged gridded daily
precipitation data set and from observed daily discharge time series, both in
a forward estimation mode (direct parameter calculation from observed data)
and in an inverse estimation mode (maximum likelihood estimation). The
performance of the linear and the nonlinear model versions is assessed in
terms of reproducing observed flow duration curves and their natural
variability. Overall, the nonlinear model version outperforms the linear
model for all regimes, but the linear model shows a notable performance
increase with catchment elevation. More importantly, the obtained results
demonstrate that the analytical model performs well for summer discharge for
all analyzed streamflow regimes, ranging from rainfall-driven regimes with
summer low flow to snow and glacier regimes with summer high flow. These
results suggest that the model's encoding of discharge-generating events
based on stochastic soil moisture dynamics is more flexible than previously
thought. As shown in this paper, the presence of snowmelt or ice melt is
accommodated by a relative increase in the discharge-generating frequency, a
key parameter of the model. Explicit quantification of this frequency
increase as a function of mean catchment meteorological conditions is left
for future research.
Automatic design of basin-specific drought indexes for highly regulated water systems
Authors: Zaniolo Marta , Giuliani Matteo , Castelletti Andrea Francesco , Pulido-Velazquez Manuel
Published: April 2018

Abstract. Socio-economic costs of drought are progressively increasing worldwide due to
undergoing alterations of hydro-meteorological regimes induced by climate
change. Although drought management is largely studied in the literature,
traditional drought indexes often fail at detecting critical events in highly
regulated systems, where natural water availability is conditioned by the
operation of water infrastructures such as dams, diversions, and pumping
wells. Here, ad hoc index formulations are usually adopted based on empirical
combinations of several, supposed-to-be significant, hydro-meteorological
variables. These customized formulations, however, while effective in the
design basin, can hardly be generalized and transferred to different
contexts. In this study, we contribute FRIDA (FRamework for Index-based
Drought Analysis), a novel framework for the automatic design of
basin-customized drought indexes. In contrast to ad hoc empirical approaches,
FRIDA is fully automated, generalizable, and portable across different
basins. FRIDA builds an index representing a surrogate of the drought
conditions of the basin, computed by combining all the relevant available
information about the water circulating in the system identified by means of
a feature extraction algorithm. We used the Wrapper for Quasi-Equally
Informative Subset Selection (W-QEISS), which features a multi-objective
evolutionary algorithm to find Pareto-efficient subsets of variables by
maximizing the wrapper accuracy, minimizing the number of selected variables,
and optimizing relevance and redundancy of the subset. The preferred variable
subset is selected among the efficient solutions and used to formulate the
final index according to alternative model structures. We apply FRIDA to the
case study of the Jucar river basin (Spain), a drought-prone and highly
regulated Mediterranean water resource system, where an advanced drought
management plan relying on the formulation of an ad hoc “state index” is
used for triggering drought management measures. The state
index was constructed empirically with a trial-and-error
process begun in the 1980s and finalized in 2007, guided by the experts from
the Confederación Hidrográfica del Júcar (CHJ). Our results
show that the automated variable selection outcomes align with CHJ's
25-year-long empirical refinement. In addition, the resultant FRIDA index
outperforms the official State Index in terms of accuracy in reproducing the
target variable and cardinality of the selected inputs set.
