Crop Water Requirements and Irrigation Schedules for Some Major Crops in Southern Iraq
Authors: Ewaid Salam Hussein , Abed Salwan Ali , Al-Ansari Nadhir
Published: April 2019

The climate of Iraq is of the subtropical semi-dry type; however, the country was rich in water resources until a few decades ago. Climate change and the construction of many dams on the Tigris and Euphrates rivers in the neighboring countries have caused water shortages and poor water quality. Now, there is a need to decrease consumption, improve management of water resources, and determine the water requirements of the major crops because agriculture is the first consumer of water in Iraq. The Food and Agriculture Organization (FAO) CROPWAT 8.0 simulation software and the CLIMWAT 2.0 tool attached to it have been used in this research for Dhi-Qar Province in southern Iraq to find the crop water requirements (CWRs) and irrigation schedules for some major crops. The CROPWAT Penman–Monteith method was used to calculate the reference crop evapotranspiration (ET0) and the United States Department of Agriculture (USDA) soil conservation (S.C.) method was used to estimate the effective rainfall. The study results showed that ET0 varied from 2.18 to 10.5 mm/day and the effective rainfall varied from 0.0 to 23.1 mm. The irrigation requirements were 1142, 203.2, 844.8, and 1180 mm/dec for wheat, barley, white corn, and tomatoes, respectively. There is a higher water demand for crops during the dry seasons (summer and autumn) and a lower demand during the wet seasons (winter and spring). The total gross irrigation and the total net irrigation were 343.8 mm and 240.7 mm for wheat, 175.2 mm and 122.6 mm for barley, 343.8 mm and 240.7 mm for white corn, and 203.3 mm and 142.3 mm for tomatoes. This study proved that the CROPWAT model is useful for calculating the crop irrigation needs for the proper management of water resources.
Recharge Impulse Spreading in Western Carpathian’s Mountainous Fissure–Karst Aquifer

Published: April 2019

Foreseen construction of a highway tunnel in the northern part of the Veľká Fatra Mts. (Slovakia) triggered the need for extensive hydrogeological investigations. The projected tunnel axis would cut through a large body buildup of Middle Triassic carbonate rocks. Dolomites and limestones with fissure–karstic permeability are surrounded by less-permeable marls, so that all springs dewatering this uplifted plate of carbonates are found above the erosion base on its edges. Detailed, hourly-based discharge monitoring of all four major springs was performed during the spring and summer period of 2014. In the meantime, groundwater table observations in two boreholes, located in the center of the fissure–karst aquifer, were run in the same time interval. Based on air temperature and precipitation records, the 2013–2014 winter period was practically without snow cover. In the middle of March 2014, an intense rainfall event caused a sudden rise of the groundwater table in the TK-04 borehole located in the southern part of the carbonate plate. Spreading of this singular hydraulic impulse throughout the structure was differently registered at individual springs within the time shift span of 1.38 to 65.25 days. Groundwater level rise of 0.40 m in the TK-04 borehole was postponed in 5.33 days. The response time of spring discharge to sudden groundwater table rise within the structure occurred later at springs with a higher water temperature. Water temperature differences between individual springs were still within the 2.46 °C narrow interval (5.57–8.03 °C). The vertical component of groundwater flux should play an important role even in a relatively simple, plate-shaped mountainous karstic aquifer fully uplifted above the erosional base, as was the case of the investigated Kopa Mt. hydrogeological structure.
BORDERLINE:
Authors: Mugarte Ilckmans Bergma
Published: April 2019

O presente trabalho visa a apresentação de um caso Borderline, com ênfase na organização do funcionamento psíquico, na dinâmica familiar e interações sociais, através do método de Rorschach e da abordagem sistêmica. O método utilizado foi o clínico qualitativo com estudo de caso e foram priorizados os dados associados à perturbação da identidade e a construção dos vínculos afetivos. O objetivo foi identificar associações entre a Representação de si e Representação de Objeto, a fim de interpretar os padrões de relacionamentos que evidenciam a compreensão dos vínculos afetivos expressos na variação entre a dependência emocional à indiferença nas relações. Os resultados revelaram que o Borderline apresenta dificuldades nos limites internos e externos e na capacidade de lidar com a fragmentação da identidade. Os pacientes limítrofes têm características que afetam a capacidade empática, ou seja, dificuldades em corresponder às expectativas e necessidades, tornando-os desregulados afetivamente, sendo intensos demais ou muito superficiais na maneira de investir nas relações. Esta organização de personalidade favorece a vulnerabilidade às frustrações, o temor do abandono e o sentimento de vazio, por não conseguir atingir a estabilidade nas representações “boas” e “más” sobre o outro. Nesta perspectiva, a necessidade de afeto se instala de modo variável, revelando a natureza impenetrável dos vínculos. A relevância do estudo nos faz compreender, de maneira profundada, a personalidade Borderline, o que afeta não só a vida destes pacientes, mas também o modo de se relacionar e de se manifestar no convívio social e com seus familiares. Ambos os métodos, oferecem instrumentos que se prestam a medir as características, tanto com relação à dinâmica individual quanto à dinâmica relacional. Pretende-se com o estudo, propor aos profissionais e interessados neste tema, discussões e estratégias a fim de realizar uma avaliação ou direcionamento clínico para que estes indivíduos possam se adaptar melhor às manifestações desse sofrimento.
Multicomponent bionanocomposites based on clay-nanoarchitectures for electrochemical devices
Authors: Lo Dico Giulia , Wicklein Bernd , Lisuzzo Lorenzo , Lazzara Giuseppe , Aranda Pilar , Ruiz-Hitzky Eduardo
Published: April 2019

Based on the unique ability of defibrillated sepiolite (SEP) to form stable and homogeneous colloidal dispersions of diverse types of nanoparticles in aqueous media under ultrasonication, multicomponent conductive nanoarchitectured materials integrating halloysite nanotubes (HNT), graphene nanoplatelets (GNP) and chitosan (CHI) have been developed. The resulting nanohybrid suspensions could be easily conformed either as films or as foams, where each individual component plays a critical role in the biocomposite: HNT acts as nanocontainer for bioactive species, GNP provide electrical conductivity (enhanced by doping with MWCNT) and, the CHI polymer matrix introduces mechanical and membrane properties, which are of key significance for the development of electrochemical devices. The resulting characteristics open the way to use these active elements as integrated multicomponent materials for advanced electrochemical devices such as biosensors and enzymatic biofuel cells. This strategy can be regarded as an “a la carte menu”, where the selection of the nanocomponents provided with diverse properties will determine a functional set of predetermined utility thanks to the SEP behavior to maintain stable colloidal dispersions of different nanoparticles and polymers in water.
A Deep Chandra View of a Candidate Parsec-scale Jet from the Galactic Center Supermassive Black Hole
Authors: Zhu Zhenlin , Li Zhiyuan , Morris Mark R. , Zhang Shuo , Liu Siming
Published: April 2019

We have investigated the linear X-ray filament, G359.944−0.052, previously identified as a likely X-ray counterpart of a parsec-scale jet from the Galactic Center supermassive black hole (SMBH) Sagittarius A* (Sgr A*), using a total of ∼5.6 Ms ultra-deep Chandra observations taken from 1999 September to 2017 July. This unprecedented data set enables us to examine flux and spectral variations that might be related to intrinsic properties of the weakly accreting SMBH. We find no flux or spectral variation in G359.944−0.052 after the G2 periapsis passage around early 2014; however, a moderate flux increase of ∼2σ significance might be associated with the periapsis passage of G1 in early 2001. The filament exhibits an unusually hard spectrum (photon index ≲1) in its portion closest to Sgr A* (i.e., near side) and a significant spectral softening in the more distant portion, which can be interpreted as synchrotron cooling of the relativistic electrons moving along the jet path. In particular, the hard spectrum of the near side suggests a piling up of quasi-monoenergetic electrons caused by rapid radiative cooling. The spectral and temporal properties of G359.944−0.052 strengthen the case for it being the X-ray counterpart of a jet launched by Sgr A*.
Effect of Different Angular Momentum Transport Mechanisms on the Distribution of Water in Protoplanetary Disks
Authors: Kalyaan Anusha , Desch Steven J.
Published: April 2019

The snow line in a protoplanetary disk demarcates regions with H2O ice from regions with H2O vapor. Where a planet forms relative to this location determines how much water and other volatiles it forms with. Giant-planet formation may be triggered at the water–snow line if vapor diffuses outward and is cold-trapped beyond the snow line faster than icy particles can drift inward. In this study, we investigate the distribution of water across the snow line, considering three different radial profiles of the turbulence parameter α(r), corresponding to three different angular momentum transport mechanisms. We consider the radial transport of water vapor and icy particles by diffusion, advection, and drift. We show that even for similar values of α, the gradient of α(r) across the snow line significantly changes the snow line location, the sharpness of the volatile gradient across the snow line, and the final water/rock ratio in planetary bodies. A profile of radially decreasing α, consistent with transport by hydrodynamic instabilities plus magnetic disk winds, appears consistent with the distribution of water in the solar nebula, with monotonically increasing radial water content and a diverse population of asteroids with different water content. We argue that Σ(r) and water abundance

are likely a diagnostic of α(r) and thus of the mechanism for angular momentum transport in inner disks.
Animal-Assisted Interventions for Treatment of Childhood Psychiatric Disorders
Authors: Shotwell Joseph Scott , Wagner Karen Dineen
Published: April 2019

Animal-assisted interventions are becoming increasingly requested by parents for the treatment of childhood psychiatric disorders. Many clinicians remain uncertain about when it is appropriate to include animals in the treatment of children and adolescents. This review examines the current evidence for the inclusion of animals in the treatment for childhood psychiatric disorders. Animals included in the treatment of childhood psychiatric disorders include dogs, guinea pigs, horses, and other assorted farm animals. Potential benefits of incorporating each animal in treating various childhood psychiatric disorders are explored. The evidence supports clinicians considering the inclusion of animal-based interventions when treating children and adolescents with autism spectrum disorder, trauma-related symptoms, and attention-deficit/hyperactivity disorder. The use of animals in the treatment of other childhood psychiatric disorders may exceed the evidence base, so additional research is required to support further treatment recommendations of animal-assisted interventions.

El Código Modelo es uno de los documentos más importantes producidos por fib. Desde su primera edición en 1970, se han publicado ediciones en 1978, 1990 y, recientemente, en 2010. Todos estos documentos han influido en la producción de códigos nacionales y regionales. Los Códigos Modelo de 1978 y 1990 han tenido una gran influencia en las diferentes versiones del Eurocódigo 2. El Código Modelo de 2010 sirve de guía de manera similar al trabajo preparatorio de CEN para las nuevas ediciones de los Eurocódigos. Los Códigos Modelo siempre han sido una referencia importante para investigadores, diseñadores y constructores. La nueva edición del Código Modelo que se publicará en 2020 pretende abordar, al mismo nivel, las estructuras nuevas y existentes y presentar modelos más generales y más racionales, eliminando cualquier rastro de reglas de diseño empírico previas. Será un Código Modelo operativo y orientado a las necesidades prácticas. Este documento muestra el contenido del nuevo Modelo de Código 2020 y el trabajo en curso para su preparación.
Chroniques de ‘carrières’. Des trajectoires créatives sous fortes influences socio-économiques
Authors: Buscatto Marie
Published: April 2019

Les industries culturelles se caractérisent par une forte prégnance de l’emploi ponctuel, flexible, incertain et à durée limitée. Ces conditions d’emploi et de travail sont le plus souvent justifiées par les employeurs aussi bien par la structuration de l’activité autour de projets non récurrents – un film, un jeu vidéo, une pièce de théâtre, une émission de radio, un disque ou une exposition -, que par la flexibilité que nécessiterait la haute intensité créative de l’activité. Les individus très qualifiés évoluant dans ces industries culturelles – e.g. designers, artistes, producteurs, concepteurs de jeux vidéos, critiques, cinéastes, attachés de presse, traducteurs, ingénieurs du son ou éditeurs - se trouvent ainsi dans des situations professionnelles incertaines et suivent des trajectoires a priori peu définies faute d’insertion dans des structures organisationnelles pérennes. Peut-on, au-delà de la forte incertitude, variabilité et flexibilité des emplois caractérisant ces secteurs d’activité, envisager l’identification de trajectoires idéales typiques relativement stables organisant l’évolution dans le temps de ces travailleurs ? Et la reconstitution systématique de ces carrières dans leur complétude et leur diversité n’enrichirait-elle pas notre compréhension des dynamiques constitutives de ces modes d’emploi et de travail ?Telle est l’approche originale construite dans cet article à travers l’exemple de la chronique jazz en France.
FGFR2 Promotes Expression of PD-L1 in Colorectal Cancer via the JAK/STAT3 Signaling Pathway
Authors: Li Piao , Huang Tingting , Zou Qi , Liu Dian , Wang Yihua , Tan Ximin , Wei Yao , Qiu Hong
Published: April 2019

Although multidisciplinary treatment is widely applied in colorectal cancer (CRC), the prognosis of patients with advanced CRC remains poor. Immunotherapy blocking of programmed cell death ligand 1 (PD-L1) is a promising approach. Binding of the transmembrane protein PD-L1 expressed by tumor cells or tumor microenvironment cells to its receptor programmed cell death 1 (PD-1) induces immunosuppressive signals and reduces the proliferation of T cells, which is an important mechanism of tumor immune escape and a key issue in immunotherapy. However, the regulation of PD-L1 expression is poorly understood in CRC. Fibroblast growth factor (FGF) receptor (FGFR) 2 causes the tyrosine kinase domains to initiate a cascade of intracellular signals by binding to FGFs and dimerization (pairing of receptors), which is involved in tumorigenesis and progression. In this study, we showed that PD-L1 and FGFR2 were frequently overexpressed in CRC, and FGFR2 expression was significantly associated with lymph node metastasis, clinical stage, and poor survival. In the current study, PD-L1 expression was positively correlated with FGFR2 expression in CRC. Tumor-derived–activated FGFR2 induced PD-L1 expression via the JAK/STAT3 signaling pathway in human CRC cells (SW480 and NCI-H716), which induced the apoptosis of Jurkat T cells. FGFR2 also promoted the expression of PD-L1 in a xenograft mouse model of CRC. The results of our study reveal a novel mechanism of PD-L1 expression in CRC, thus providing a theoretical basis for reversing the immune tolerance of FGFR2 overexpression in CRC.
Heart failure in the elderly: A geriatric syndrome. Picture of the modern situation
Authors: Fagotto Valentina , Cavarape Alessandro , Boccanelli Alessandro
Published: April 2019

Among the older patients’ cohort, the aetiology of heart failure is peculiar and differs in many ways from the younger one, both in its epidemiology, diagnostic work-up and clinical presentation. Focusing on this population, we could assume that heart failure is a real geriatric syndrome, characterized by several features, which coexist with other comorbidities and require specific and targeted cares. It is therefore necessary to examine the global burden of heart failure and the patient’s history rather than the causal cardiomyopathy - frequently more than one in the elderly - facing with the condition, bearing in mind the quality of life even before its duration.
Risk management in a bulk coal export logistic chain: A stakeholder perspective
Authors: Botha André , Badenhorst-Weiss J. A.
Published: April 2019

Background: In South Africa, the export of coal is a large contributor to the gross domestic product. Statistics indicate that the export of coal is stagnant or declining, which indicates a risk for coal as a foreign exchange earner. A study into the risks facing the bulk coal export logistics chain is therefore of great importance. Any risk to this logistics chain will directly affect its efficiency and contribution to foreign exchange. The nature of a logistics supply chain is such that risks to one stakeholder (partner or node) affect not only that stakeholder’s own operations but also those of the other partners and the whole supply chain’s efficiency and sustainability.Objectives: The objective of the study was to identify and explore the risks and risk management practices in the bulk coal export logistics chain from a stakeholder theory perspective.Methods: A qualitative research design was used, and in-depth, structured interviews were conducted with different stakeholders in the chain. A total of eight interviews were conducted, audio-recorded, transcribed and analysed by means of a thematic analysis.Results: Many risks were identified in the bulk coal export logistics chain, and of these risks, it was found that the most important ones were infrastructure, the macro-economy and people-related risks. The findings revealed evidence of underlying tensions between different stakeholders with regard to investment to mitigate infrastructure risks. The findings suggest that there is a lack of communication and an aligned vision among the stakeholders in the logistics chain and that they strategise for their risks separately.Conclusion: Close cooperation on a high level between the stakeholders in the logistics chain is needed to strategise for risk mitigation in an integrated, holistic manner.
La monoparentalidad derivada de la violencia de género: análisis de la cuestión
Authors: Ramón Fernández Francisca
Published: April 2019

En el presente estudio abordaremos la situación de monoparentalidad, pero no en un sentido general, sino que atenderemos a la que se produce como consecuencia y derivada de la violencia de género. Cierto es que se carece de una legislación estatal que atienda a esta situación, pero ello no es óbice para que sean cada vez más el número de familias monoparentales o monomarentales. Tomando como pretexto el Decreto 19/2018, de 9 de marzo, del Consell, por el que se regula el reconocimiento de la condición de familia monoparental en la Comunitat Valenciana, vamos a ocuparnos de cómo se contempla en los casos de violencia de género. Hay que tener en cuenta la afectación al menor, así como la necesidad de articular mecanismos de protección suficientes teniendo en cuenta necesidades de inclusión en nuestra sociedad, y se plantean algunas cuestiones que es necesario darles una respuesta (por ejemplo, la situación de la vivienda habitual; la custodia compartida en la situación de violencia de género, entre otras). La metodología que se va a utilizar será un análisis de la normativa, se atenderá a la postura de la doctrina especializada en orden a determinar cómo mejorar la situación de la unidad familiar afectada. De dicho estudio extraeremos unas conclusiones para observar el grado de protección que concede la normativa, así como cómo se podría mejorar la situación de una monoparentalidad no elegida, sino derivada de una situación de violencia.

Abstract. The phenomenon of “cloud voids”, i.e., elongated volumes inside a
cloud that are devoid of droplets, was observed with laser sheet photography
in clouds at a mountain-top station. Two experimental cases, similar in
turbulence conditions yet with diverse droplet size distributions and cloud
void prevalence, are reported. A theoretical explanation is proposed based on
the study of heavy inertial sedimenting particles inside a Burgers vortex. A
general conclusion regarding void appearance is drawn from theoretical
analysis. Numerical simulations of polydisperse droplet motion with realistic
vortex parameters and Mie scattering visual effects accounted for can explain
the presence of voids with sizes similar to that of the observed ones.
Clustering and segregation effects in a vortex tube are discussed for
reasonable cloud conditions.
Identification of soil-cooling rains in southern France from soil temperature and soil moisture observations
Authors: Zhang Sibo , Meurey Catherine , Calvet Jean-Christophe
Published: April 2019

Abstract. In this study, the frequency and intensity of soil-cooling rains is assessed
using in situ observations of atmospheric and soil profile variables in
southern France. Rainfall, soil temperature, and topsoil volumetric soil
moisture (VSM) observations, measured every 12 min at 21 stations of the
SMOSMANIA (Soil Moisture Observing System – Meteorological Automatic Network
Integrated Application) network, are analyzed over a time period of 9 years,
from 2008 to 2016. The spatial and temporal statistical distribution of the
observed rainfall events presenting a marked soil-cooling effect is
investigated. It is observed that the soil temperature at a depth of 5 cm
can decrease by as much as 6.5 ∘C in only 12 min during a
soil-cooling rain. We define marked soil-cooling rains as rainfall events
triggering a drop in soil temperature at a depth of 5 cm larger than
1.5 ∘C in 12 min. Under Mediterranean and
Mediterranean–mountain climates, it is shown that such events occur up to nearly
3 times a year, and about once a year on average. This frequency decreases to
about once every 3.5 years under semi-oceanic climate. Under oceanic climate,
such pronounced soil-cooling rains are not observed over the considered
period of time. Rainwater temperature is estimated for 13 cases of marked
soil-cooling rains using observed changes within 12 min in soil temperature
at a depth of 5 cm, together with soil thermal properties and changes in
VSM. On average, the estimated rainwater temperature is generally lower than
the observed ambient air temperature, wet-bulb temperature, and topsoil
temperature at a depth of 5 cm, with mean differences of −5.1, −3.8, and
−11.1 ∘C, respectively. The most pronounced differences are
attributed to hailstorms or to hailstones melting before getting to the soil
surface. Ignoring this cooling effect can introduce biases in land surface
energy budget simulations.
Convective distribution of dust over the Arabian Peninsula: the impact of model resolution
Authors: Bukowski Jennie , van den Heever Susan C.
Published: April 2019

Abstract. Along the coasts of the Arabian Peninsula, convective dust storms are a considerable source of mineral dust to the atmosphere. Reliable predictions of convective dust events are necessary to determine their effects on air quality, visibility, and the radiation budget. In this study, the Weather Research and Forecasting Model coupled with Chemistry (WRF-Chem) is used to simulate a 2016 summertime dust event over the Arabian Peninsula and examine the variability in dust fields and associated vertical transport due to the choice of convective parameterization and explicit versus parameterized convection. Simulations are run at 45 km and 15 km grid spacing with multiple cumulus parameterizations, and are compared to a 3 km simulation that permits explicit convective processes. Five separate cumulus parameterizations at 15 km grid spacing were tested to quantify the spread across different parameterizations. Finally, the impact these variations have on radiation, specifically aerosol heating rates is also investigated. On average, in these simulations the explicit case produces higher quantities of dust than the parameterized cases in terms of dust uplift potential, vertical dust concentrations, and vertical dust fluxes. Major drivers of this discrepancy between the simulations stem from the explicit case exhibiting higher surface windspeeds during convective activity, lower dust emission wind threshold velocities due to drier soil, and more frequent, stronger vertical velocities which transport dust aloft and increase the atmospheric lifetime of these particles. For aerosol heating rates in the lowest levels, the shortwave effect prevails in the explicit case with a net cooling effect, whereas a longwave net warming effect is present in the parameterized cases. The spread in dust concentrations across cumulus parameterizations at the same grid resolution (15 km) is an order of magnitude lower than the impact of moving from parameterized to explicit convection. We conclude that tuning dust emissions in coarse resolution simulations can only improve the results to first-order and cannot fully rectify the discrepancies originating from disparities in the representation of convective dust transport.
How bias correction goes wrong: measurement of XCO2 affected by erroneous surface pressure estimates
Authors: Kiel Matthäus , O'Dell Christopher W. , Fisher Brendan , Eldering Annmarie , Nassar Ray , MacDonald Cameron G. , Wennberg Paul O.
Published: April 2019

Abstract. All measurements of XCO2 from space have systematic errors. To
reduce a large fraction of these errors, a bias correction is applied to
XCO2 retrieved from GOSAT and OCO-2 spectra using the ACOS
retrieval algorithm. The bias correction uses, among other parameters, the
surface pressure difference between the retrieval and the meteorological
reanalysis. Relative errors in the surface pressure estimates, however,
propagate nearly 1:1 into relative errors in bias-corrected
XCO2. For OCO-2, small errors in the knowledge of the pointing
of the observatory (up to ∼130 arcsec) introduce a bias in
XCO2 in regions with rough topography. Erroneous surface
pressure estimates are also caused by a coding error in ACOS version 8,
sampling meteorological analyses at wrong times (up to 3 h after the
overpass time). Here, we derive new geolocations for OCO-2's eight footprints
and show how using improved knowledge of surface pressure estimates in the
bias correction reduces errors in OCO-2's v9 XCO2 data.
Inputs and processes affecting the distribution of particulate iron in the North Atlantic along the GEOVIDE (GEOTRACES GA01) section
Authors: Gourain Arthur , Planquette Hélène , Cheize Marie , Lemaitre Nolwenn , Menzel Barraqueta Jan-Lukas , Shelley Rachel , Lherminier Pascale , Sarthou Géraldine
Published: April 2019

Abstract. The aim of the GEOVIDE cruise (May–June 2014, R/V Pourquoi Pas?)
was to provide a better understanding of trace metal biogeochemical cycles in
the North Atlantic Ocean. As marine particles play a key role in the global
biogeochemical cycle of trace elements in the ocean, we discuss the
distribution of particulate iron (PFe), in relation to the distribution of
particulate aluminium (PAl), manganese (PMn), and phosphorus (PP). Overall,
32 full vertical profiles were collected for trace metal analyses,
representing more than 500 samples. This resolution provides a solid basis
for assessing concentration distributions, elemental ratios, size
fractionation, and adsorptive scavenging processes in key areas of the
thermohaline overturning circulation. Total particulate iron concentrations
ranged from as low as 9 pmol L−1 in surface waters of the Labrador Sea
to 304 nmol L−1 near the Iberian margin, while median PFe
concentrations of 1.15 nmol L−1 were measured over the sub-euphotic
ocean interior. Within the Iberian Abyssal Plain, the ratio of PFe to PAl was identical to
the continental crust molar ratio (0.21 mol mol−1), indicating the
important influence of crustal particles in the water column. Overall, the
lithogenic component explained more than 87% of PFe variance along the
section. Within the Irminger and Labrador basins, the formation of biogenic
particles led to an increase in the PFe∕PAl ratio (up to
0.64 mol mol−1) compared to the continental crust ratio. Continental
margins induce high concentrations of particulate trace elements within the
surrounding water masses (up to 10 nmol L−1 of PFe). For example,
horizontal advection of PFe was visible more than 250 km away from the
Iberian margin. Additionally, several benthic nepheloid layers were observed
more than 200 m above the seafloor along the transect, especially in the
Icelandic, Irminger, and Labrador basins, suspending particles with high PFe
content of up to 89 nmol L−1.
2-D finite displacements and finite strain from PIV analysis of plane-strain tectonic analogue models
Authors: Boutelier David , Schrank Christoph , Regenauer-Lieb Klaus
Published: April 2019

Abstract. Image correlation techniques have provided new ways to analyze the distribution in space and time of deformation in analogue models of tectonics. Here we demonstrate how the correlation of successive time-lapse images of a deforming model allows not only to evaluate the components of the strain-rate tensor at any time in the model but also calculate the finite displacements and finite strain tensor. We illustrate, using synthetic images, the ability of the algorithm to produce maps of the velocity gradients, small-strain tensor components, but also incremental or instantaneous principal strains and maximum shear. The incremental displacements can then summed up using a Eulerian or a Lagrangian summation, and the components of the 2-D finite strain tensor can be calculated together with the finite principal strain and maximum finite shear. We benchmark the measures of finite displacements using specific synthetic tests for each summation mode. The deformation gradient tensor is calculated from the deformed state, and decomposed into the finite rigid-body rotation and left or right finite stretch tensors, allowing the deformation ellipsoids to be drawn. The finite strain has long been the only quantified measure of strain in analogue models. The presented software package allows producing these finite strain measures while also accessing incremental measures of strain. The more complete characterization of the deformation of tectonic analogue models will facilitate the comparison with numerical simulations and geological data, and help produce conceptual mechanical models.

Marx, Shakespeare e o nexo do dinheiro
Authors: Cotrim Ana
Published: April 2019

Este artigo se volta ao caderno intitulado “Dinheiro” dos Manuscritos econômico-filosóficos de 1844, de Marx, em que se abordam as consequências perniciosas do nexo do dinheiro para a formação da sensibilidade. A fim de concretizar esses efeitos e elucidar esse nexo, Marx cita uma longa passagem do Tímon de Atenas, de Shakespeare. A apropriação de Marx dessa peça evidencia seu interesse no modo como conformações sociais afetam a subjetividade, a personalidade humana e as relações interpessoais; e como a retomada da sensibilidade paranós constitui uma finalidade revolucionária para Marx, talvez o fim último da emancipação.
Challenges of Population-based Measurement of Suicide Prevention Activities Across
Multiple Health Systems

Published: April 2019

Suicide is a preventable public health problem. Zero Suicide (ZS) is a suicide
prevention framework currently being evaluated by Mental Health Research Network
investigators embedded in six Health Care Systems Research Network (HCSRN) member health
systems implementing ZS. This paper describes ongoing collaboration to develop
population-based process improvement metrics for use in, and comparison across, these
and other health systems. Robust process improvement metrics are sorely needed by the
hundreds of health systems across the country preparing to implement their own best
practices in suicide care. Here we articulate three examples of challenges in using
health system data to assess suicide prevention activities, each in ascending order of
complexity: 1) Mapping and reconciling different versions of suicide risk assessment
instruments across health systems; 2) Deciding what should count as adequate suicide
prevention follow-up care and how to count it in different health systems with different
care processes; and 3) Trying to determine whether a safety planning discussion took
place between a clinician and a patient, and if so, what actually happened. To develop
broadly applicable metrics, we have advocated for standardization of care processes and
their documentation, encouraged standardized screening tools and urged they be recorded
as discrete electronic health record (EHR) variables, and engaged with our clinical
partners and health system data architects to identify all relevant care processes and
the ways they are recorded in the EHR so we are not systematically missing important
data. Serving as embedded research partners in our local ZS implementation teams has
facilitated this work.

Background: Appendicitis is a common surgical emergency in children, yet diagnosis
can be challenging. An electronic health record (EHR) based, clinical decision support
(CDS) system called Appy CDS was designed to help guide management of pediatric patients
with acute abdominal pain within the Health Care Systems Research Network
(HCSRN).Objectives: To describe the development and implementation of a clinical
decision support tool (Appy CDS) built independently but synergistically at two large
HCSRN affiliated health systems using well-established platforms, and to assess the
tool’s Triage component, aiming to identify pediatric patients at increased risk for
appendicitis.Results: Despite differences by site in design and implementation, such as
the use of alerts, incorporating gestalt, and other workflow variations across sites,
using simple screening questions and automated exclusions, both systems were able to
identify a population with similar appendicitis rates (11.8 percent and 10.6 percent),
where use of the full Appy CDS would be indicated.Discussion: These 2 HCSRN sites
designed Appy CDS to capture a population at risk for appendicitis and deliver CDS to
that population while remaining locally relevant and adhering to organizational
preferences. Despite different approaches to point-of-care CDS, the sites have
identified similar cohorts with nearly identical background rates of appendicitis.Next
Steps: The full Appy CDS tool, providing personalized risk assessment and tailored
recommendations, is undergoing evaluation as part of a pragmatic cluster randomized
trial aiming to reduce reliance on advanced diagnostic imaging. The novel approaches to
CDS we present could serve as the basis for future ED interventions.

Context: In existence for nearly 25 years, the Healthcare Systems Research Network
(HCSRN) is an established and sustainable network of health care systems that serves as
a “real world” laboratory to enable the integration of research findings into practice.
The objective of this paper is to demonstrate how the HCSRN serves as an ideal
environment for studying dissemination and implementation of evidence-based practices
into health care systems through the example of developing a multi-site study on the
implementation of evidence-based precision medicine practices.Case description: The
“Implementing Universal Lynch Syndrome Screening (IMPULSS)” study (NIH R01CA211723)
involves seven HCSRN health care systems and two external health care systems. The
IMPULSS study will describe and explain organizational variability around Lynch syndrome
(LS) screening to identify which factors in different organizational contexts are
important for successful implementation of LS screening programs and will create a
toolkit to facilitate organizational decision making around implementation and
improvement of precision medicine programs in health care systems.Major Themes: The
strengths of the HCSRN that facilitate D&I research include: 1) a culture of
collaboration, 2) standardization of data and processes across systems, and 3)
researchers embedded in diverse health care systems. We describe how these strengths
contributed to developing the IMPULSS study.Conclusion: Given the importance of
conducting research in real world settings to improve patient outcomes, the unique
strengths of the HCSRN are of vital importance. The IMPULSS study is one case example of
how the strengths of the HCSRN make it an excellent environment for research on
implementing evidence-based precision medicine practices in health care
systems.

Published: April 2019

Al planificar acciones y diseñar estrategias en la educación superior siempre se habla de identificar retos. Generalmente éstos se señalan de manera muy puntual, entre más concisa mejor. El producto resultante es una lista de elementos obvios y a veces repetitivos. Además, por requerimiento del proceso, éstos deben plantearse de tal manera que admitan un rastreo cuantitativo de la solución que seguidamente se les ha de proponer. El formato en el que se realizan estas reflexiones no permite que pensemos
A biblioteca do futuro: um olhar no passado
Authors: Jesus Deise Lourenço de , Cunha Murilo Bastos da
Published: April 2019

Introdução: Em 1929, McDevitt já relatava que grandes mudanças ocorreriam nas bibliotecas e  os problemas que elas enfrentariam estariam mais relacionados aos recursos financeiros do que a tecnologia propriamente. Isto acabou não sendo o grande obstáculo das bibliotecas e são as mudanças e os avanços da tecnologia que colocam em risco a sobrevivência da biblioteca tradicional. Objetivo: O trabalho propõe apresentar ideias de autores da Biblioteconomia e da Ciência da Informação sobre a biblioteca do futuro e as mudanças tecnológicas e sociais que estas sofreriam nos anos seguintes. Metodologia: Revisão de literatura que cobre o período de 1945 a 2003. Resultados: A pesquisa revela que a literatura central em torno das bibliotecas remete à transição do físico para o digital, e todo o processo que as bibliotecas deveriam passar em termos financeiros, de pessoal e de tecnologias, além de possíveis barreiras e limitações para essa transição. Conclusões: Conclui-se que mesmo com todo o potencial previsto para o desenvolvimento da biblioteca digital, o movimento de transição não aconteceu tão rápido nem na mesma proporção que os autores imaginaram e que a transição ainda não está completa.
Um estudo das contribuições de Schopenhauer para a Ciência da Informação: o mundo como vontade e representação
Authors: Sousa Janailton Lopes , Sá Ramalho Rogério Aparecido
Published: April 2019

Introdução: Arthur Schopenhauer foi um filósofo alemão do século XIX autor do livro intitulado 'O Mundo como Vontade e Representação', publicado originalmente em 1819, onde aborda a complexa relação entre representação e o modo como o homem interpreta a realidade. Objetivo: Analisar as contribuições de Arthur Schopenhauer, identificadas na obra 'O Mundo como Vontade e Representação', verificando aproximações com corpus teórico da Ciência da Informação, principalmente em relação aos trabalhos desenvolvidos por Wittgenstein (1968) e Dahlberg (1978), referentes ao estudo da Linguagem e Teoria do Conceito. Metodologia: A pesquisa enquadra-se como teórica, de caráter analítico e utilizou como procedimentos metodológicos atividades de revisão,  análise e interpretação da literatura selecionada. Resultados: A partir do estudo realizado foi possível inferir que os trabalhos desenvolvidos por Wittgenstein (1968) e Dahlberg (1978) no âmbito da área de Ciência da Informação foram influenciados pela concepção de representação apresentada na obra de Schopenhauer, considerando que as representações fundamentam o entendimento humano sobre o funcionamento da realidade como se conhece, desenvolvidas como formas para codificar a natureza, e as relações entre os seres, em uma linguagem assimilável à razão. Conclusões: Schopenhauer oferece uma concepção de representação que pode ser incorporada no campo da Ciência da Informação, pois entende que os conceitos são elementos chave da representação, abarcando a relação sujeito e objeto, o conhecimento seria o resultado dessa relação e uma forma de representação do mundo.

Introdução: A qualificação, criação e ampliação de Programas de Pós-Graduação strictu sensu (PPG) são ações estratégicas e fundamentais à produção científica e intelectual brasileira. Consequentemente, estes programas precisam ser constantemente avaliados visando a sua melhoria. No campo da Ciência da Informação (CI) estas ações têm se intensificado. Objetivo: Elaborar e aplicar uma sistemática para o diagnóstico do potencial de atuação de um PPGCI recém implementado, visando identificar seu comportamento e vocação para a produção cientifica na área. Metodologia: Análise de conteúdo de relatórios do sistema de avaliação da CAPES; identificação e mapeamento da produção cientifica de docentes permanentes do PPGCI da Universidade Federal de São Carlos (UFSCar); estabelecimento de base comparativa da produção intelectual do PPGCI UFSCar, com o PPGCI da Universidade Federal de Minas Gerais. Resultados: A partir da análise dos dados e das comparações estabelecidas, foi possível constatar o engajamento e a pró-atividade do corpo docente do PPGCI UFSCar na submissão dos resultados de suas pesquisas para publicação em eventos e periódicos qualificados na área. Ao mesmo tempo evidenciam-se lacunas na colaboração entre os pesquisadores, tanto internos ao Programa quanto vinculados a outras instituições. Conclusões: Explicita-se a necessidade de elaborar estratégias visando mobilizar os atores deste processo a investirem na produção científica e em redes de colaboração, de modo que possam contribuir na promoção do impacto científico e social do PPGCI. A metodologia utilizada também se mostrou eficaz para ser usada por outros PPGs em fases iniciais de implementação, que almejem estabelecer estratégias para sua consolidação e crescimento.
