Potential Role for Osteocalcin in the Development of Atherosclerosis and Blood Vessel Disease
Authors: Tacey Alexander , Qaradakhi Tawar , Brennan-Speranza Tara , Hayes Alan , Zulli Anthony , Levinger Itamar
Published: October 2018

There is increasing evidence for the involvement of the skeleton in the regulation of atherosclerotic vascular disease. Osteocalcin, an osteoblast derived protein, exists in two forms, carboxylated and undercarboxylated osteocalcin. Undercarboxylated osteocalcin has been linked to the regulation of metabolic functions, including glucose and lipid metabolism. Features of atherosclerosis have been associated with circulating osteocalcin; however, this association is often conflicting and unclear. Therefore, the aim of this review is to examine the evidence for a role of osteocalcin in atherosclerosis development and progression, and in particular endothelial dysfunction and vascular calcification. The current literature suggests that undercarboxylated osteocalcin stimulates the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signaling pathway to upregulate nitric oxide and nuclear factor kappa β (NF-кβ) in vascular cells, possibly protecting endothelial function and preventing atherogenesis. However, this effect may be mediated by metabolic factors, such as improvements in insulin signaling, rather than through a direct effect on the vasculature. Total osteocalcin is frequently associated with vascular calcification, an association that may occur as a result of vascular cells eliciting an osteogenic phenotype. Whether osteocalcin acts as a mediator or a marker of vascular calcification is currently unclear. As such, further studies that examine each form of osteocalcin are required to elucidate if it is a mediator of atherogenesis, and whether it functions independently of metabolic factors.
Preparation of Reduction-Responsive Camptothecin Nanocapsules by Combining Nanoprecipitation and In Situ Polymerization for Anticancer Therapy
Authors: Song Xiao-Qing , Tao Cheng , Li Wei , Wang Jie-Xin , Le Yuan , Zhang Jian-Jun
Published: October 2018

Stimuli-responsive systems for controlled drug release have been extensively explored in recent years. In this work, we developed a reduction-responsive camptothecin (CPT) nanocapsule (CPT-NC) by combining nanoprecipitation and in situ polymerization using a polymerized surface ligand and a disulfide bond-containing crosslinker. Dissolution rate studies proved that the CPT-NCs have robust drug-release profiles in the presence of glutathione (GSH) owing to the division of the disulfide bond crosslinker which triggers the collapse of the polymer layer. Furthermore, the in vitro investigations demonstrated that the CPT-NCs exhibited a high-cellular uptake efficiency and cytotoxicity for cancer cells of squamous cell carcinoma (SCC-15). Our approach thus presents an effective intracellular drug delivery strategy for anticancer therapy.

Authors: Lim Xin Yan , Yeo Quan Qi , Kng Grace Li Lin , Chung Wing Lam , Yap Kai Zhen
Published: October 2018

Background: This study aims to evaluate the inter-rater reliability and perceived usability of a newly developed drug-related problem (DRP) classification system for use by pharmacists in the intermediate and long-term care (ILTC) setting in Singapore. Methods: This was a cross-sectional survey study involving the use of a self-administered questionnaire. All 55 pharmacists affiliated to the Pharmaceutical Society of Singapore (PSS) ILTC Pharmacists Workgroup who were above 21 years old and not authors of the classification system were invited to participate. The inter-rater reliability of participants’ classification of 46 mock DRP cases using the new DRP classification system was determined using Fleiss’s kappa (κ). Participants’ perceived usability of the classification system was evaluated using six items with five-point Likert scales (1—“strongly disagree”, 5—“strongly agree”). Results: Thirty-three pharmacists responded to the survey. Overall inter-rater reliability was found to be substantial (κ = 0.614; 95% CI: 0.611–0.617). All usability items received positive ratings (“strongly agree” or “agree”) from at least 69% of participants. Conclusion: The new DRP classification system has substantial external validity and appears to be suitable for use by pharmacists to document and report DRPs in the ILTC setting in Singapore and facilitate evaluation of the impact of pharmaceutical care in the ILTC setting.
Fabrication of Photothermo-Responsive Drug-Loaded Nanogel for Synergetic Cancer Therapy
Authors: Chang Ray , Tsai Wei-Bor
Published: October 2018

Temperature stimulus, easy modulation in comparison to other environmental stimuli, makes thermo-responsive nanocarriers popular in the applications of controlled drug release for cancer therapy. In this study, photosensitive sodium copper chlorophyllin (SCC) was incorporated into thermo-responsive polymeric nanogels consisted of N-isopropylacrylamide and N-(hydroxymethyl)acrylamide. Significant heat was generated from the SCC-containing nanogels under the exposure to 532-nm green laser, and resulted in cell mortality. The thermo-responsive nanogel loaded with 5-FU, an anti-cancer drug, released the drug explosively when exposed to green laser. The combination of hyperthermia and temperature-induced drug release via green laser irradiation greatly enhanced cell mortality to a maximal extent. Such photothermo-responsive nanogel possesses a great potential in anti-cancer treatment.

Published: October 2018

Accurate estimates of above ground biomass (AGB) are needed for monitoring carbon in tropical forests. LiDAR data can provide precise AGB estimations because it can capture the horizontal and vertical structure of vegetation. However, the accuracy of AGB estimations from LiDAR is affected by a co-registration error between LiDAR data and field plots resulting in spatial discrepancies between LiDAR and field plot data. Here, we evaluated the impacts of plot location error and plot size on the accuracy of AGB estimations predicted from LiDAR data in two types of tropical dry forests in Yucatán, México. We sampled woody plants of three size classes in 29 nested plots (80 m2, 400 m2 and 1000 m2) in a semi-deciduous forest (Kiuic) and 28 plots in a semi-evergreen forest (FCP) and estimated AGB using local allometric equations. We calculated several LiDAR metrics from airborne data and used a Monte Carlo simulation approach to assess the influence of plot location errors (2 to 10 m) and plot size on ABG estimations from LiDAR using regression analysis. Our results showed that the precision of AGB estimations improved as plot size increased from 80 m2 to 1000 m2 (R2 = 0.33 to 0.75 and 0.23 to 0.67 for Kiuic and FCP respectively). We also found that increasing GPS location errors resulted in higher AGB estimation errors, especially in the smallest sample plots. In contrast, the largest plots showed consistently lower estimation errors that varied little with plot location error. We conclude that larger plots are less affected by co-registration error and vegetation conditions, highlighting the importance of selecting an appropriate plot size for field forest inventories used for estimating biomass.
DInSAR for a Regional Inventory of Active Rock Glaciers in the Dry Andes Mountains of Argentina and Chile with Sentinel-1 Data
Authors: Villarroel Cristian , Tamburini Beliveau Guillermo , Forte Ana , Monserrat Oriol , Morvillo Monica
Published: October 2018

The Dry Andes region of Argentina and Chile is characterized by a highly developed periglacial environment. In these arid or semi-arid regions, rock glaciers represent one of the main pieces of evidence of mountain creeping permafrost and water reserves in a solid state. However, their distribution, degree of activity, and response to global warming are not yet well understood. In this context, this work aims to show the potential of the Sentinel-1-based interferometric technique (DInSAR) to map active rock glaciers at a regional level. In particular, the paper presents an active rock glacier inventory for the study area, which covers approximately 40,000 km2, ranging from latitude 30°21′S to 33°21′S. A total of 2116 active rock glaciers have been detected, and their elevations show a high correlation with the west-east direction. This result was obtained by using only 16 interferometric pairs. Compared to other remote sensing classification techniques, the interferometric technique offers a means to measure surface displacement (active rock glacier). This results in a reliable classification of the degree of activity compared to other methods, based on geomorphological, geomorphometric, and/or ecological criteria. This work presents evidence of this aspect by comparing the obtained results with existing optical data-based inventories. We conclude that the combination of both types of sensors (radar and optical) is an appropriate procedure for active rock glacier inventories, as both mapping methodologies are complementary.
Mindfulness Training at School: A Way to Engage Adolescents with Sustainable Consumption?
Authors: Böhme Tina , Stanszus Laura S. , Geiger Sonja M. , Fischer Daniel , Schrader Ulf
Published: October 2018

A central challenge in research on education for sustainable consumption (ESC) is to develop new approaches to engage adolescents with sustainable consumption (SC) in a way that addresses not only the cognitive but also the socio-emotional and behavioral levels. Mindfulness-based interventions (MBIs) that foster awareness, (self-)reflection, and ethical values could potentially leverage learning processes in ESC. The present study was the first one to investigate the potential effects of a consumption-specific MBI on sustainable consumption behavior (SCB) in the areas of nutrition and clothing. The eight-week long intervention was carried out with 15-year old adolescents (N = 85) directly at school. A randomized pre-post waitlist control group design with mixed methods was applied. The study revealed the strong effects of the adapted MBI on precursors of SCB and further effects not directly related to but potentially conducive for SCB. Actual behavioral effects were minor. Substantial inter-individual differences and inconsistencies between qualitative and quantitative results imply case-related effects that do not allow generalizable conclusions to be drawn. Nevertheless, the results of this pilot study indicate that combining mindfulness training with ESC formats appears to be a feasible and fruitful approach to engage adolescents with SC. Future practice and research should consider more diverse target groups, other consumption areas, and longer periods for interventions and their evaluation.
Two Types of Intuitionistic Fuzzy Covering Rough Sets and an Application to Multiple Criteria Group Decision Making
Authors: Wang Jingqian , Zhang Xiaohong
Published: October 2018

Intuitionistic fuzzy rough sets are constructed by combining intuitionistic fuzzy sets with rough sets. Recently, Huang et al. proposed the definition of an intuitionistic fuzzy (IF) β -covering and an IF covering rough set model. In this paper, some properties of IF β -covering approximation spaces and the IF covering rough set model are investigated further. Moreover, we present a novel methodology to the problem of multiple criteria group decision making. Firstly, some new notions and properties of IF β -covering approximation spaces are proposed. Secondly, we study the characterizations of Huang et al.’s IF covering rough set model and present a new IF covering rough set model for crisp sets in an IF environment. The relationships between these two IF covering rough set models and some other rough set models are investigated. Finally, based on the IF covering rough set model, Huang et al. also defined an optimistic multi-granulation IF rough set model. We present a novel method to multiple criteria group decision making problems under the optimistic multi-granulation IF rough set model.
The Performance of Multiple Model-Simulated Soil Moisture Datasets Relative to ECV Satellite Data in China
Authors: Bai Wenkui , Gu Xiling , Li Shenlin , Tang Yihan , He Yanhu , Gu Xihui , Bai Xiaoyan
Published: October 2018

Reliability and accuracy of soil moisture datasets are essential for understanding changes in regional climate such as precipitation and temperature. Soil moisture datasets from the Essential Climate Variable (ECV), the Coupled Model Intercomparison Project Phase 5 (CMIP5), the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP), the Global Land Data Assimilation System (GLDAS), and reanalysis products are widely used. These datasets generated by different techniques are compared in a common framework over China in this study. The comparison focuses on four aspects: spatial pattern, temporal correlation, long-term trend, and the relationships with precipitation and the Normalized Difference Vegetation Index (NDVI). The results indicate that all soil moisture datasets reach a good agreement on the spatial patterns of wet and dry soil. These patterns are also consistent with that of precipitation. However, there are considerable discrepancies in the absolute values of soil moisture among these datasets. In terms of unbiased Root-Mean-Square Difference (unRMSE, i.e., removing the differences in absolute values), all modeled datasets obtain performances comparable with ECV observations. Our results also suggest that a multi-model ensemble of soil moisture datasets can improve the representation of soil moisture conditions. The optimal dataset from which the wetting/drying trends in soil moisture have the highest consistency in terms of changes in precipitation and NDVI varies by season. Specifically, in spring, CMIP5 in northwest China shows that the trends in soil moisture are consistent with the changes in precipitation and NDVI. In summer, ECV presents the most identical performance compared to the changes in precipitation and NDVI. In autumn, GLDAS and Reanalysis have better performance in south China and parts of north China. In winter, GLDAS performs the best in the east of south China, followed by the Reanalysis dataset. These discrepancies among the datasets present various changes in different regions, which should be well noted and discussed before use.

New Methods for Finding Activity-sensitive Spectral Lines: Combined Visual Identification and an Automated Pipeline Find a Set of 40 Activity Indicators
Authors: Wise A. W. , Dodson-Robinson S. E. , Bevenour K. , Provini A.
Published: October 2018

Starspots, plages, and activity cycles cause radial velocity variations that can either mimic planets or hide their existence. To verify the authenticity of newly discovered planets, observers may search for periodicity in spectroscopic activity indices such as Ca H & K and Hα, then mask out any Doppler signals that match the activity period or its harmonics. However, not every spectrograph includes Ca H & K, and redder activity indicators are needed for planet searches around low-mass stars. Here, we show how new activity indicators can be identified by correlating spectral line depths with a well-known activity index. We apply our correlation methods to archival HARPS spectra of ϵ Eri and α Cen B and use the results from both stars to generate a master list of activity-sensitive lines whose core fluxes are periodic at the star’s rotation period. Our newly discovered activity indicators can in turn be used as benchmarks to extend the list of known activity-sensitive lines toward the infrared or UV. With recent improvements in spectrograph illumination stabilization, wavelength calibration, and telluric correction, stellar activity is now the biggest noise source in planet searches. Our suite of >40 activity-sensitive lines is a first step toward allowing planet hunters to access all the information about spots, plages, and activity cycles contained in each spectrum.
Kinematics of Highly r-process-enhanced Field Stars: Evidence for an Accretion Origin and Detection of Several Groups from Disrupted Satellites
Authors: Roederer Ian U. , Hattori Kohei , Valluri Monica
Published: October 2018

We present the kinematics of 35 highly r-process-enhanced ([Eu/Fe] ≥ +0.7) metal-poor (−3.8 < [Fe/H] < −1.4) field stars. We calculate six-dimensional positions and velocities, evaluate energies and integrals of motion, and compute orbits for each of these stars using parallaxes and proper motions from the second Gaia data release and published radial velocities. All of these stars have halo kinematics. Most stars (66%) remain in the inner regions of the halo (<13 kpc), and many (51%) have orbits that pass within 2.6 kpc of the Galactic center. Several stars (20%) have orbits that extend beyond 20 kpc, including one with an orbital apocenter larger than the Milky Way virial radius. We apply three clustering methods to search for structure in phase space, and we identify eight groups. No abundances are considered in the clustering process, but the [Fe/H] dispersions of the groups are smaller than would be expected by random chance. The orbital properties, clustering in phase space and metallicity, and the lack of highly r-process-enhanced stars on disk-like orbits, indicate that such stars likely were accreted from disrupted satellites. Comparison with the galaxy luminosity–metallicity relation suggests M

V
 ≳ −9 for most of the progenitor satellites, characteristic of ultra-faint or low-luminosity classical dwarf spheroidal galaxies. Environments with low rates of star formation and Fe production, rather than the nature of the r-process site, may be key to obtaining the [Eu/Fe] ratios found in highly r-process-enhanced stars.

Published: October 2018

Aperture synthesis arrays are commonly used in radio astronomy to take images of radio point sources, with the planned Square Kilometre Array (SKA) being the most common example. One approach to enhancing the quality of the images is to optimize an antenna array configuration in a possible SKA implementation. An ideal arrangement must ensure optimal configurations to capture a clear image by either decreasing the sidelobe level (SLL) in the l–m domain or increasing the sampled data in the spatial-frequency domain. In this paper a novel configuration is considered to optimize the array by considering all possible observation situations through the positions of the antenna array elements via a mathematical model that we call geometrical method (GM). To demonstrate its efficiency, the technique is applied to developing an optimal configuration for the elements of the Giant Metrewave Radio Telescope (GMRT). The effect of these changes, particularly in the forms of circular and spiral arrangements, is discussed. It is found that a spiral configuration results in fewer overlapping samples than the number of antennas placed along three arms of the GMRT with fewer than 11% and 27% overlapping samples in the snapshot and 6 hr tracking observations, respectively. Finally, the spiral configuration reduces the first SLL from −13.01 dB, using the arms of the current GMRT configuration, to −15.64 dB.

Published: October 2018

As an evolutionary phase of galaxies, active galactic nuclei (AGNs) over a large range of redshifts have been utilized for understanding cosmic evolution. In particular, the population and evolution of AGNs have been investigated through the study of the cosmic X-ray background in various fields. As one of the deep fields observed by Chandra, with a total of 2.8 Ms exposures, Abell 133 is a special region for investigating AGNs, providing a testbed for probing the environmental effects on AGN triggers, since cluster environments can be different from field environments. The achieved flux limits of data at the 50% completeness levels of 6.95 × 10−16, 1.43 × 10−16, and 1.57 × 10−15 erg s−1 cm−2 are 0.5–8, 0.5–2, and 2–8 keV. Using the wavdetect and no-source binomial probability (i.e., p < 0.007), we analyze the combined Chandra image, detecting 1617 (in 0.5–8 keV), 1324 (in 0.5–2 keV), and 1028 (in 2–8 keV) X-ray point sources in the Abell 133 region. Here, we present the X-ray point source catalog with the source fluxes, which can be combined with multiwavelength data for future works. We find that the number count distribution of the X-ray point sources is well reproduced with a broken power-law model, while the best-fit model parameters are sensitive to the fitting range of the number count distribution. Finally, we find an excess of number density (a decrease of AGN fraction) at the central region of the cluster, which reflects the effect of dense environments on AGN triggers, a finding similar to those of other studies of galaxy clusters.
The Arizona Radio Observatory CO Mapping Survey of Galactic Molecular Clouds. VI. The Cep OB3 Cloud (Cepheus B and C) in CO J = 2–1, 13CO J = 2–1, and CO J = 3–2

Published: October 2018

We present (1) new fully sampled maps of CO and

 J = 2–1 emission and CO J = 3–2 emission toward the molecular clouds Cep B and C, associated with the Cep OB3 association; (2) a map of extinction, A

V
, derived from IR colors of background stars; and (3) the distribution of young stellar objects (YSOs) over the same field as the molecular maps. An LTE analysis of the CO and

 maps yields the distribution of molecular column densities and temperatures. Substantial variations are evident across the clouds; smaller subregions show correlations between molecular properties and dust extinction, consistent with a picture of outer photodissociation regions with a layer of CO-dark molecular gas, a CO self-shielded interior, and an inner cold dense region where CO is largely depleted onto grains. Comparing the distribution of YSOs with molecular gas surface density shows a power-law relation very similar in slope to that for the giant molecular cloud associated with the H ii region Sh2-235 from a previous paper in this series that employed the same methodology. We note the presence of several compact, isolated CO emission sources in the J = 3–2 maps. The gas temperature and

 velocity dispersion yield a map of the sonic Mach number, which varies across the cloud but always exceeds unity, confirming the pervasiveness of supersonic turbulence over length scales ≳0.1 pc (the map resolution). We also compute a J = 2–1 CO X-factor that varies with position but is, on average, within 20% of the Galactic average derived from CO J = 1–0 observations.
First illustration of chromosomes and genetic system of Lecanodiaspidinae (Homoptera, Coccinea, Asterolecaniidae s.l.)
Authors: Gavrilov-Zimin Ilya A.
Published: October 2018

The karyotype of Psoraleococcusmultipori (Morrison, 1921) was studied for the first time, based on material from Indonesia (Sulawesi). The diploid chromosome number was found to be 18 in both males and females, but some cells contained also additional small chromosomal elements, probably B chromosomes. About 50 % of the studied embryos demonstrated paternal genome heterochromatinization of one haploid set of chromosomes (PGH) suggesting presence of a Lecanoid genetic system. The embryos with PGH are known to be always the male embryos in scale insects and so, bisexual reproduction may be presumed for P.multipori. The information provided represents the first probative cytogenetic data for the subfamily Lecanodiaspidinae Targioni Tozzetti, 1896 as a whole. A detailed morphological figure and photos of female and male embryonic cells are given. Additionally, it was discovered that the females of P.multipori exhibit complete ovoviviparity.
Comprendre le dépôt de plainte des victimes de viol : facteurs individuels et circonstanciels
Authors: Vanier Camille , Langlade Aurélien
Published: October 2018

Le viol est une atteinte qui présente une particularité très intéressante pour la recherche dans la mesure où il s’agit de l’infraction sexuelle la plus grave et la plus traumatisante pour la victime, mais pour autant, du crime le moins rapporté aux autorités. Réalisée à partir de l’enquête de victimation française, cette étude a pour objectif d’apporter des éléments d’explication sur la décision de déposer plainte ou non à la suite d’un viol. Des analyses en régression logistique ont notamment permis de révéler que les déterminants du dépôt de plainte pour un viol hors ménage pouvaient être différents de ceux pour l’intra-ménage.
Y a-t-il une sexualité sans tiers ?
Authors: Herbin Celya
Published: October 2018

On oublie trop souvent que l’exposition de la sexualité infantile dans une psychanalyse ne fait que transformer le rapport à l’Autre, nullement d’en faire cesser le procès, de sorte qu’elle demeure en arrière-plan de la sexualité dite adulte où le sujet découvre, surpris, que l’Autre subsiste peu ou prou, au moins sous la forme d’une altérité qui s’impose dans le fantasme. Ce point clinique essentiel méritait, me semble-t-il, d’être rappelé pour éviter toute confusion sur l’issue d’une psychanalyse et c’est à partir de la cure d’une analysante, Clotilde, que je me propose de le déployer.
Dans la ronde des fantasmes, le rival – fantasme de prostitution et passage à l’acte
Authors: Bulat-Manenti Gorana
Published: October 2018

Cet article propose d’examiner la place de fantasme inconscient et ses mécanismes, autour de la figure du Rival, et la nécessité psychique de mettre en place cette figure paternelle. Le père, ce premier rival, se manifeste avec le fantasme « un enfant est battu » dont proviennent les autres fantasmes inconscients, comme celui, plus difficile à assumer, du parricide. Dans différentes structures psychiques, la place du fantasme est plus ou moins solide, et dans certaines conditions il peut se transformer en un passage à l’acte. La présence du fantasme du sauveur est ici examinée dans sa duplicité entre l’amour et la haine à partir des œuvres de Kessel, Buñuel et Ozon.
Réciprocité dans l’homosexualité
Authors: Brun Danièle
Published: October 2018

Avoir un corps anatomiquement comparable, bien que non identique, avec une même configuration d’orifices, serait-ce là une des sources de l’attrait homosexuel ? L’auteure en réponse à cette question interroge la littérature analytique notamment les notions de narcissisme et de choix d’objet telles qu’introduites par Freud en 1914. Elles apportent au thème de la réciprocité entre deux personnes du même sexe l’articulation permettant de lier le besoin du corps au désir sexuel.
De l’amour courtois au passage à l’acte sexuel
Authors: Lauru Didier
Published: October 2018

Après une description historique de l’amour courtois, écrit et chanté par les troubadours, l’auteur se réfère à la théorie freudienne et aux concepts lacaniens pour comparer l’impossible du rapport sexuel, structurel, et les fantasmes des analysants névrotiques. Puis, s’appuyant sur sa pratique analytique, l’auteur se réfère aux comportements contemporains en matière de relations sexuelles. Beaucoup d’analysants décrivent comment ils rencontrent des petits autres, seulement pour avoir des rapports sexuels avec eux via Internet, clivés de tout sentiment amoureux. C’est une autre façon, avec l’amour courtois, de contourner le fait structurel qu’il n’y a pas de rapport sexuel.
L’énigme du féminin dans La Vénus à la fourrure de Sacher-Masoch
Authors: Ben Miled Aïcha
Published: October 2018

Le livre de Sacher-Masoch, La Vénus à la fourrure illustre fort à propos la question du désir entre hommes et femmes. Ainsi, dans le cadre de cette autobiographie romancée, l’auteur dévoile ses fantasmes masochistes. Et il fallait tout le courage et la liberté de Sacher-Masoch pour pousser la démonstration jusqu’à son paroxysme. Ce texte propose donc une lecture psychanalytique de l’univers particulier du roman. L’analyse du jeu érotique qui s’instaure entre les deux héros nous amènera à conclure que la femme devra d’elle-même renoncer à occuper cette place de dominatrice, sous peine de ne plus pouvoir se constituer comme sujet du manque et donc comme sujet désirant pour elle-même.
La présidentialisation du système français depuis 2002 à travers la fonction de popularité
Authors: Boya Christophe
Published: October 2018

L’objectif de cet article est de proposer une estimation des fonctions de popularité de l’exécutif en France de 2002 à 2016. Nous testons l’hypothèse de responsabilité et utilisons des variables économiques, subjectives et politiques sur la popularité. Les résultats montrent que les variables testées sont significatives et soulignent que le président ne peut plus utiliser le premier ministre comme bouc émissaire. L’article met en évidence que le système politique français a évolué vers un système présidentiel, où la responsabilité de l’exécutif est double, affectant à la fois le président et le premier ministre.
Philanthropie et notabilité urbaine
Authors: Brejon de Lavergnée Matthieu
Published: October 2018

Augustin Cochin (1823-1872), quoiqu’oublié, offre une porte d’entrée efficace pour penser l’articulation entre philanthropie et notabilité dans une ville comme Paris fortement marquée par la « question sociale ». Bourgeois, parisien de longue date, Cochin jouit d’un capital social et politique familial qu’il enrichit de ses propres engagements confessionnels et philanthropiques. Il présente ainsi un parcours en relative rupture mais qui consonne surtout avec les préoccupations du milieu du XIX e siècle : condition ouvrière, enquête leplaysienne, réforme des prisons, éducation populaire, esclavage. S’il accède à d’intéressantes positions administratives, il échoue cependant à convertir sa ressource philanthropique en gain électoral qui suppose d’autres modes d’agir. Il est bien l’homme d’une France des notables.
Les mondes sociaux de la charité parisienne en 1900
Authors: Topalov Christian
Published: October 2018

On utilise l’analyse de réseaux pour dresser une carte des mondes de la charité parisienne, de façon à en donner une vision d’ensemble sans jamais perdre de vue les individualités qui les composent. Un modèle simplifié est construit en sélectionnant les personnes qui sont recensées dans les répertoires charitables comme jouant un rôle majeur dans au moins deux œuvres différentes. On définit comme un lien entre deux personnes le fait d’être affiliées à une même œuvre, et la chaîne de ces liens dessine une représentation du réseau charitable parisien. Celui-ci est divisé en diverses régions : celles de l’archevêché, des confessions protestante et israélite, de l’ establishment réformateur, des œuvres semi-officielles de la haute bourgeoisie titrée des régimes précédents, de la bienfaisance républicaine, enfin. Ces régions sont toutefois interconnectées par une série d’institutions et de personnes qui sont précisément identifiées et dont on propose une typologie. Cette cartographie sociale permet de comprendre pourquoi la charité parisienne constituait une zone de trêve, voire de coopération entre les deux camps dont le conflit avait l’Affaire Dreyfus pour terrain et symbole.
Repenser la Providence sans perdre Dieu dans l’opération
Authors: Durand Emmanuel
Published: October 2018

À l’écoute de suggestions actuelles pour repenser la Providence, en affinité avec l’ Open Theism , cet article mène un exercice de discernement puis de reconstruction. L’examen critique porte sur trois remaniements sensibles : un transfert inaperçu de souveraineté de Dieu vers l’être humain, une autodétermination de Dieu à se laisser déterminer par ses créatures libres, une suspension de l’omniscience divine au bénéfice supposé de la liberté humaine. De tels déplacements sont mesurés à leurs lourdes conséquences. La reconstruction revisite l’affrontement des images de Dieu, païennes ou chrétienne ; puis considère les rapports étonnants entre nécessités et libertés selon l’évangile de Luc. Cela conduit à reformuler l’essentiel de la foi en la Providence suivant les trois articles du Credo , en termes de souveraineté, mystère pascal et synergie.
Michel de Certeau, Henri de Lubac : une correspondance

Published: October 2018

À Henri de Lubac, Michel de Certeau a pu écrire qu’il lui devait sa vocation jésuite et, encore en 1983, « ce qu’il y a de plus essentiel ». Leur correspondance (qui ne nous est connue que par ses lettres) révèle une relation qu’il qualifie de « filiale et fraternelle ». Importante surtout dans les années 1960 – quand il exerce des responsabilités à Christus et se fait l’historien de la spiritualité de la Compagnie à l’époque moderne –, elle s’interrompt ensuite presque complètement ; aussi faisons-nous appel à une autre source, dans une dernière partie de notre étude, pour tenter d’éclairer cette quasi rupture : les lettres entre Lubac et Henri Bouillard.
Addenda to the lichen flora of the Ticino river valley (western Po Plain, Italy)
Authors: Gheza Gabriele
Published: October 2018

The Ticino river valley is a focal area for biodiversity in the western Po Plain (Northern Italy). Lichens have been collected by the author from 91 sites in the period 2011-2017. These collections and the few literature data published in the last decade have been summarized. Twenty-eight species (15 terricolous, 5 epiphytic, 3 lignicolous, 3 saxicolous, 1 epiphytic and lignicolous, 1 terricolous and epiphytic), mostly belonging to genus Cladonia, are reported here as addenda to the floristic list published 15 years ago by the Lombardy Ticino Park, which included 123 species. Many of the newly recorded species are interesting under a conservation or biogeographical standpoint.
Influence of foreign alliances on the performance of small-scale agricultural businesses in South Africa: A new institutional economics perspective
Authors: Rambe Patient , Agbotame Livingstone A.K.
Published: October 2018

Background: Globalisation has accentuated the need for small-scale agricultural businesses (SSABs) to network horizontally and vertically into world markets. However, the capacity of SSABs to cement foreign alliances to capitalise on business opportunities that the expansion of global markets presents, while simultaneously mitigating against the negative forces of globalisation remains a grey area.Aim: The study sought to contribute to internationalisation literature by examining: (1) the extent to which SSABs’ owner and/or managers in selected South African provinces establish foreign alliances, (2) whether there are any statistically significant differences in SSABs’ performance based on their extent of establishment of foreign alliances.Setting: The setting for this study was Vryburg-Pokwani in the North West and Northern Cape provinces of South Africa, respectively.Method: A survey was conducted on 151 SSAB owner and/or managers in the aforementioned study area.Results: The results revealed that although a majority (51.7%) had some (i.e. few) foreign alliances, 48.3% of SSABs had no foreign alliances at all. The results also demonstrated that the establishment of foreign alliances was positively and statistically significantly related to the performance of SSABs in the Vryburg-Pokwani area. Post-hoc comparisons (Bonferroni) results showed that while SSABs with 1–2 foreign alliances perform better than those with no foreign alliances at all, those SSABs with 6–10 foreign alliances perform better than those with none, 1–2 and 3–5 foreign linkages respectively.Conclusion: Since SSABs with foreign alliances tended to outperform those that were dependent on domestic links, the extent to which the economic benefits derived from internationalisation are reinvested into the businesses for the continued sustenance of businesses needs more rigorous investigation.
Vitamin D deficiency in elderly: Risk factors and drugs impact on vitamin D status
Authors: Kweder Hasan , Eidi Housam
Published: October 2018

Introduction: Vitamin D (VD) deficiency is a major public health problem worldwide. In spite of its high prevalence, particularly among elderly people, VD deficiency is still underestimated by many physicians. Increasingly, VD deficiency is associated with several known geriatric syndromes. Methods: The study sample consisted of 125 patients, aged 75 years and older, admitted to the acute geriatric unit. The plausible association between the serum 25-hydroxyvitamin D [25(OH)D] level and patient age, sex, body mass index, renal function, cholecystectomy history, and the prescribed drugs had been investigated. The Fisher's exact test was used to conduct the statistical analysis of data. Results: Surprisingly, furosemide treatment was correlated with normal 25(OH)D levels and an increased incidence of secondary hyperparathyroidism. Unlike the other four parameters mentioned above, our data showed that only the patient sex exhibited a significant association with 25(OH)D level as elderly males suffered from a serious VD deficiency as compared to elderly females. Conclusion: Old age is an independent risk factor for VD deficiency. The supplementary dose of VD should be precisely defined to achieve the optimal serum 25(OH)D level in elderly people. The definition of the normal serum 25(OH)D threshold in elderly furosemide-treated patients is worth of further studies.

Published: October 2018

The designing of an efficient warehouse management system is a key factor to improve productivity and reduce costs. The use of Automated Guided Vehicles (AVGs) in Material Handling Systems (MHS) and Flexible Manufacturing Systems (FMS) can help to that purpose. This paper is intended to provide insight regarding the technical and financial suitability of the implementation of a fleet of AGVs. This is carried out by means of a fuzzy set/qualitative comparative analysis (fsQCA) by measuring the level of satisfaction of managerial decision makers.
Impact of urban canopy meteorological forcing on aerosol concentrations

Published: October 2018

Abstract. The regional climate model RegCM4 extended with the land surface model CLM4.5
was coupled to the chemistry transport model CAMx to analyze the impact of
urban meteorological forcing on surface fine aerosol (PM2.5)
concentrations for summer conditions over the 2001–2005 period, focusing on
the area of Europe. Starting with the analysis of the meteorological
modifications caused by urban canopy forcing, we found a significant increase
in urban surface temperatures (up to 2–3 K), a decrease of specific humidity (by
up to 0.4–0.6 gkg−1), a reduction of wind speed (up to −1 ms−1) and an enhancement of vertical turbulent diffusion coefficient
(up to 60–70 m2s−1). These modifications translated into significant changes in surface aerosol
concentrations that were calculated by a “cascading” experimental approach.
First, none of the urban meteorological effects were considered. Then, the
temperature effect was added, then the humidity and the wind, and finally, the
enhanced turbulence was considered in the chemical runs. This facilitated the
understanding of the underlying processes acting to modify urban aerosol
concentrations. Moreover, we looked at the impact of the individual aerosol
components as well. The urbanization-induced temperature changes resulted in
a decrease of PM2.5 by −1.5 to −2 µg m−3, while decreased
urban winds resulted in increases by 1–2 µg m−3. The enhanced
turbulence over urban areas resulted in decreases of PM2.5 by −2 µg m−3. The combined effect of all individual impact depends on
the competition between the partial impacts and can reach up to −3 µg m−3 for some cities, especially when the temperature impact was stronger
in magnitude than the wind impact. The effect of changed humidity was found
to be minor. The main contributor to the temperature impact is the
modification of secondary inorganic aerosols, mainly nitrates, while the wind
and turbulence impact is most pronounced in the case of primary aerosol (primary
black and organic carbon and other fine particle matter). The overall as well
as individual impacts on secondary organic aerosol are very small, with the
increased turbulence acting as the main driver. The analysis of the vertical
extent of the aerosol changes showed that the perturbations caused by urban
canopy forcing, besides being large near the surface, have a secondary
maximum for turbulence and wind impact over higher model levels, which is
attributed to the vertical extent of the changes in turbulence over urban
areas. The validation of model data with measurements showed good agreement,
and we could detect a clear model improvement in some areas when including
the urban canopy meteorological effects in our chemistry simulations.
Satellite observations of aerosols
and clouds over southern China from 2006 to 2015: analysis of changes and possible interaction mechanisms

Published: October 2018

Abstract. Aerosol and cloud properties over southern China during the 10-year period 2006–2015 are analysed based on observations from passive and active satellite sensors and emission data. The results show a decrease in aerosol optical depth over the study area by about 20 % on average, accompanied by an increase in liquid cloud cover and cloud liquid water path (LWP) by 5 % and 13 %, respectively. Analysis of aerosol types and emissions suggests that the main driver for their reduction is a decrease in biomass burning aerosols. These changes occurred mainly in late autumn and early winter months and coincided with changes in cloud properties. For the latter, possible explanatory mechanisms were examined, including changes in circulation patterns and aerosol-cloud interactions. Further analysis of changes in aerosol vertical profiles demonstrates a consistency of the observed aerosol and cloud changes with the aerosol semi-direct effect, which depends on their relative heights. Based on this mechanism, fewer absorbing aerosols in the cloud layer would lead to an overall decrease in evaporation of cloud droplets, thus increasing cloud LWP and cover.
Precipitation pattern in the Western Himalayas revealed by four datasets
Authors: Li Hong , Haugen Jan Erik , Xu Chong-Yu
Published: October 2018

Abstract. Data scarcity is the biggest problem for scientific research
related to hydrology and climate studies in the Great Himalayas region.
High-quality precipitation data are difficult to obtain due to a sparse
network, cold climate and high heterogeneity in topography. In this paper, we
examine four datasets in northern India of the Western Himalayas:
interpolated gridded data based on gauge observations (IMD,
1∘×1∘, and APHRODITE,
0.25∘×0.25∘), reanalysis data (ERA-Interim,
0.75∘×0.75∘) and high-resolution simulation by a
regional climate model (WRF, 0.15∘×0.15∘). The four
datasets show a similar spatial pattern and temporal variation during the
period 1981–2007, though the absolute values vary significantly
(497–819 mm year−1). The differences are
particularly large in July and August at the windward slopes and
high-elevation areas. Overall, the datasets show that the summer is getting
wetter and the winter is getting drier, though most of the trends in monthly
precipitation are not significant. Trend analysis of summer and winter
precipitation at every grids confirms the changes. Wetter summers will result
in more and bigger floods in the downstream areas. Warmer and drier winters
will result in less glacier accumulation. All the datasets show
consistency in the period 1981–2007 and can give a spatial overview of the
precipitation in the region. Comparing with the Bhuntar gauge data, the WRF
dataset gives the best estimates of extreme precipitation. To conclude, we
recommend the APHRODITE dataset and the WRF dataset for hydrological studies
for their improved spatial variation which match the scale of hydrological
processes as well as accuracy in extreme precipitation for flood simulation.
Season-ahead forecasting of water storage and irrigation requirements – an application to the southwest monsoon in India

Published: October 2018

Abstract. Water risk management is a ubiquitous challenge faced by stakeholders in the
water or agricultural sector. We present a methodological framework for
forecasting water storage requirements and present an application of this
methodology to risk assessment in India. The application focused on
forecasting crop water stress for potatoes grown during the monsoon season
in the Satara district of Maharashtra. Pre-season large-scale climate
predictors used to forecast water stress were selected based on an
exhaustive search method that evaluates for highest ranked probability skill
score and lowest root-mean-squared error in a leave-one-out cross-validation
mode. Adaptive forecasts were made in the years 2001 to 2013 using
the identified predictors and a non-parametric k-nearest neighbors approach.
The accuracy of the adaptive forecasts (2001–2013) was judged based on
directional concordance and contingency metrics such as hit/miss rate and
false alarms. Based on these criteria, our forecasts were correct 9 out
of 13 times, with two misses and two false alarms. The results of
these drought forecasts were compared with precipitation forecasts from the
Indian Meteorological Department (IMD). We assert that it is necessary to
couple informative water stress indices with an effective forecasting
methodology to maximize the utility of such indices, thereby optimizing
water management decisions.
