A numerical method to improve the spatial interpolation of water vapor from numerical weather models: a case study in South and Central America
Authors: Fernández Laura I. , Meza Amalia M. , Natali M. Paula , Bianchi Clara E. 
Published: December 2019

Abstract. Commonly, numerical weather model (NWM) users can get the vertically integrated water vapor (IWV) value at a given location from the values at nearby grid points. In this study we used a validated and freely available global navigation satellite system (GNSS) IWV data set to analyze the very well-known effect of height differences. To this end, we studied the behavior of 67 GNSS stations in Central and South America with the prerequisite that they have a minimum of 5 years of data during the period from 2007 to 2013. The values of IWV from GNSS were compared with the respective values from ERA-Interim and MERRA-2 from the same period.
Firstly, the total set of stations was compared in order to detect cases in which the geopotential difference between GNSS and NWM required correction. An additive integral correction to the IWV values from ERA-Interim was then proposed. For the calculation of this correction, the multilevel values of specific humidity and temperature given at 37 pressure levels by ERA-Interim were used. The performance of the numerical integration method was tested by accurately reproducing the IWV values at every individual grid point surrounding each of the GNSS sites under study.
Finally, considering the IWVGNSS values as a reference, the improvement introduced to the IWVERA-Interim values after correction was analyzed. In general, the corrections were always recommended, but they are
not advisable in marine coastal areas or on islands as at least two grid points of the model are usually in the water. In such cases, the additive correction could overestimate the IWV.
Spiky fluctuations and scaling in high-resolution EPICA ice core dust fluxes
Authors: Lovejoy Shaun , Lambert Fabrice 
Published: December 2019

Abstract. Atmospheric variability as a function of scale has been divided in various
dynamical regimes with alternating increasing and decreasing fluctuations:
weather, macroweather, climate, macroclimate, and megaclimate. Although a vast
amount of data are available at small scales, the larger picture is not well
constrained due to the scarcity and low resolution of long paleoclimatic
time series. Using statistical techniques originally developed for the study of turbulence, we analyse the fluctuations of a centimetric-resolution dust flux time series from the EPICA Dome C ice core in Antarctica that spans the past 800 000 years. The temporal resolution ranges from annual at the top of the core to 25 years at the bottom, enabling the detailed statistical analysis and comparison of eight glaciation cycles and the subdivision of each cycle into eight consecutive phases. The unique span and resolution of the dataset allows us to analyse the macroweather and climate scales in detail. We find that the interglacial and glacial maximum phases of each cycle showed particularly large macroweather to climate transition scale τc (around 2 kyr), whereas mid-glacial phases feature centennial transition scales (average of 300 years). This suggests that interglacials and glacial maxima are exceptionally stable when compared with the rest of a glacial cycle. The Holocene (with τc≈7.9 kyr) had a particularly large τc, but it was not an outlier when compared with the phases 1 and 2 of other cycles. We hypothesize that dust variability at larger (climate) scales appears to be predominantly driven by slow changes in glaciers and vegetation cover,
whereas at small (macroweather) scales atmospheric processes and changes in
the hydrological cycles are the main drivers. For each phase, we quantified the drift, intermittency, amplitude, and extremeness of the variability. Phases close to the interglacials (1, 2, 8)
show low drift, moderate intermittency, and strong extremes, while the
“glacial” middle phases 3–7 display strong drift, weak intermittency, and weaker extremes. In other words, our results suggest that glacial maxima, interglacials, and glacial inceptions were characterized by relatively stable atmospheric conditions but punctuated by frequent and severe droughts, whereas the mid-glacial climate was inherently more unstable.
Non-linear aspects of the tidal dynamics in the Sylt-Rømø Bight, south-eastern North Sea

Published: December 2019

Abstract. This study is dedicated to the tidal dynamics in the
Sylt-Rømø Bight with a focus on the non-linear processes. The FESOM-C
model was used as the numerical tool, which works with triangular,
rectangular or mixed grids and is equipped with a wetting/drying option. As
the model's success at resolving currents largely depends on the quality of
the bathymetric data, we have created a new bathymetric map for an area
based on recent studies of Lister Deep, Lister Ley, Højer Deep and
Rømø Deep. This new bathymetric product made it feasible to work
with high-resolution grids (up to 2 m in the wetting/drying zone). As a
result, we were able to study the tidal energy transformation and the role
of higher harmonics in the domain in detail. For the first time, the tidal
ellipses, maximum tidally induced velocities, energy fluxes and residual
circulation maps were constructed and analysed for the entire bight.
Additionally, tidal asymmetry maps were introduced and constructed. The full
analysis was performed on two grids with different structures and showed a
convergence of the results as well as fulfilment of the energy balance. A
great deal of attention has been paid to the selection of open-boundary conditions, model validation against tide gauges and recent in situ current
data. The tidal residual circulation and asymmetric tidal cycles largely
define the circulation pattern, transport and accumulation of sediment, and
the distribution of bedforms in the bight; therefore, the results presented
in the article are necessary and useful benchmarks for further studies in
the area, including baroclinic and sediment dynamics investigations.
Evaluating the effects of soil erosion and productivity decline on soil carbon dynamics using a model-based approach
Authors: Bouchoms Samuel , Wang Zhengang , Vanacker Veerle , Van Oost Kristof 
Published: December 2019

Abstract. Sustained accelerated soil erosion alters key soil
properties such as nutrient availability, water holding capacity, soil depth
and texture, which in turn have detrimental effects on crop productivity and
therefore reduce C input to soils. In this study, we applied a 1-D soil
profile model that links soil organic carbon (SOC) turnover, soil erosion
and biomass production. We used observational data to constrain the
relationship between soil erosion and crop productivity. Assuming no change
in effort, we evaluated the model performance in terms of SOC stock
evolution using published observational data from 10 catchments across
Europe and the USA. Model simulations showed that accounting for
erosion-induced productivity decline (i) increased SOC losses by 37 % on
average compared to a scenario where these effects were excluded, and (ii) improved the prediction of SOC losses when substantial soil truncation takes
place. Furthermore, erosion-induced productivity decline reduced
soil–atmosphere C exchanges by up to 30 % after 200 years of transient
simulation. The results are thus relevant for longer-term assessments and
they stress the need for integrated soil–plant models that operate at the
landscape scale to better constrain the overall SOC budget.
'La casa de papel', 'Rita' y 'Merlí': entre nuevas narrativas y viejos patriarcados
Authors: Bonavitta Paola 
Published: December 2019

Netflix ha venido desafiando, en cierta forma, algunos de los roles tradicionales que ocupan las mujeres en los medios de comunicación. Ha incorporado series que han buscado desestabilizar los estereotipos sexistas clásicos para proponer nuevos protagonismos, otras miradas y diversas posibilidades de ser heroínas. En este artículo trabajamos con tres series que presentan nuevas perspectivas narrativas para mujeres y que centralizan gran parte del argumento en ellas: Rita, La Casa de Papel y Merlí. Se trata de tres historias creadas por fuera de las producciones imperialistas e, incluso, del idioma inglés. A partir de un Análisis Crítico del Discurso pautado por la metodología feminista, analizamos las construcciones de mujeres que se presentan en estas ficciones, así como los estereotipos sexistas que se ponen en juego, se desafían y se formulan en el marco de estos tres programas. Desde el análisis de contenido mediático, nos centramos en las representaciones sociales de género que se producen y se concretan en la nueva apuesta de la industria cultural.
A pesar de que estas series parecen atender a nuevas demandas de la sociedad, incorporando personajes y narrativas que apelan a la diversidad y a la contestación, es posible sugerir que ese movimiento se dirige más a atraer nichos de mercado en la industria del entretenimiento que a proponer una crítica social más amplia y profunda.
Hemoperitoneum Secondary to Liver Lobe Torsion in a Cat
Authors: Knight Rebekah , McClaran Janet Kovak 
Published: December 2019

ABSTRACTA 5 yr old male British blue shorthair cat was presented collapsed with hypotension, hypothermia, and cranial abdominal pain. Abdominal ultrasound and abdominocentesis revealed hemoperitoneum and a suspected hepatic mass. Cytology of fine-needle aspirates of the mass was inconclusive, so exploratory celiotomy was performed for diagnostic and therapeutic purposes. An enlarged, hemorrhagic papillary process of the caudate lobe was identified, with twisting of the vasculature at the hilus, so a complete lobectomy was performed using a thoracoabdominal stapler. Histopathology was consistent with liver lobe torsion with no evidence of hepatocellular neoplasia identified. This report describes the first case of hemoperitoneum secondary to liver lobe torsion without evidence of hepatocellular neoplasia in a cat and demonstrates a successful outcome following surgical management with liver lobectomy.

Abstract
Orogenic Au deposits have contributed the majority of Au recovered globally throughout history. However, the mechanism that concentrates Au to extremely high bonanza grades in small domains within these deposits remains enigmatic. The volume of fluid required to provide extreme Au endowments in localized occurrences is not reflected in field observations (e.g., in the extent of quartz veining or hydrothermal alteration). Detailed optical, scanning and transmission electron microscopy, nanoscale secondary ion mass spectrometry, and 3-D neutron tomography have been used to investigate the processes responsible for development of anomalously high grade ore (upward of 3% Au) found in quartz veins at Fosterville gold mine (Victoria, Australia). Distinct textural settings of visible Au include (1) Au concentrated along pressure solution seams associated with wall-rock selvages, (2) as nano- to microscale dusty Au seams parallel to pressure solution seams, and (3) in microscale tension fractures perpendicular to stylolitic seams. The distribution of Au in arsenopyrite and pyrite hosted within pressure solution seams changes as a function of the extent of deformation. Sulfides in highly deformed pressure solution seams exclusively host Au as nano- to micrometer-sized clusters within features associated with corrosion and brittle failure, whereas sulfides in mildly deformed pressure solution seams have Au bound in the crystal structure. It is proposed that Au supersaturation in fluids introduced during seismic periods led to the deposition of abundant Au nanoparticles in quartz-carbonate veins. Subsequent pressure dissolution of vein quartz and carbonate during interseismic intervals allowed for episodic increase in the Au/quartz ratio and permitted liberation and migration of Au nanoparticles, promoting Au grain growth in favorable textural settings. Galvanic corrosion and brittle fracturing of auriferous sulfides during the interseismic period allowed additional remobilization and/or enrichment of sulfide-hosted Au. Repetition of this mechanism over the time scale of deposit formation acted to concentrate Au within the lodes. This Au ore upgrading model, referred to as “aseismic refinement,” provides a new insight for the genesis of ultrarich Au mineralization and, based on textures reported from many Au deposits, may be a globally significant component in the formation of orogenic Au deposits.
Los vampiros del conurbano: La calambre de Ángel Mosquito
Authors: Venturini Maria Ximena 
Published: December 2019

En las últimas décadas, las nociones de espacio y lugar y el concepto general de espacialidad se han hecho prominentes tanto en las ciencias sociales como en las humanidades. Geógrafos como David Harvey y teóricos críticos como Edward Soja han llamado la atención sobre el espacio como una realidad producida simbólicamente, desde donde cuyos significados no se dan de antemano. Desde este punto focal, este trabajo estudiará la novela gráfica argentina La calambre(2017) dibujada y escrita por Ángel Mosquito. Esta es la historia de dos vampiros marginales de los suburbios de Buenos Aires. Estos vampiros, siendo cartoneros, buscan reintegrarse en la sociedad, tratando de silenciar los calambres que el hambre les produce. Propongo estudiar la representación literaria de este espacio que recodifica y reconstruye esta geografía olvidada, señalando simultáneamente la identidad cultural presente en esta área de Buenos Aires.
Del cómic a la novela gráfica: mutaciones editoriales de la historieta colombiana en el siglo XXI
Authors: Conde Aldana Juan Alberto 
Published: December 2019

La expresión novela gráfica ha sido discutida extensamente tanto por autores de cómics como por críticos y teóricos. generalmente desde aproximaciones formales o históricas. En este artículo propongo una aproximación descriptiva al conjunto de producciones englobadas bajo dicha etiqueta en el contexto colombiano, país que vive en la actualidad un inusitado crecimiento editorial, y que ha encontrado en la publicación de novelas gráficas una de sus líneas más exitosas. Para ello, propongo una aproximación teórica a la expresión “novela gráfica” desde la perspectiva de los estudios editoriales (Darnton, Bhaskar), y desde la teoría de la paratextualidad de Gérard Genette, que permita mostrar cómo, desde la presencia de esta etiqueta en los entornos peritextuales y epitextuales del circuito editorial en el que se inscriben las publicaciones, la han convertido en un auténtico marco dinamizador de esta forma cultural emergente.
Evaluation of E-business micro and macro determinants by Multiple Indicators Multiple Causes model
Authors: Remeikiene Rita , Cepel Martin , Gaspareniene Ligita 
Published: December 2019

The methods employed for the research include comparative and systematic literature analysis, statistical data analysis, expert evaluation and the Multiple Indicators Multiple Causes (MIMIC) model. There are several research gaps in the field of e-business: 1) there is no simplified factor model which would denote the development of e-business, including its causes and consequences, and which, due to its universality, could be adapted to any country; 2) the studies of e-business development lack a comprehensive assessment which would consider this phenomenon in both quantitative and qualitative terms.
On the basis of the theoretical analysis, a model for assessment of e-business development has been formed. The results of the empirical evaluation have revealed that in the group of micro environmental determinants development of e-business in Lithuania is, to the largest extent, determined by business managers’ motivation to reach the defined aims and their positive viewpoint that e-business may become a perfect auxiliary tool to ensure business competitiveness. In the group of macro environmental determinants, the determinants of socio-cultural environment can be indicated as the major ones that affect the development of e-business. Application of the MIMIC model has enabled to identify the following macro economical determinants (for the euro area): real effective exchange rate for the euro area; level of households with the Internet access; quantity of individuals using the Internet for ordering goods or services; government deficit/surplus; youth employment, and individuals using the Internet for interaction with public authorities.

Authors: Ribeiro Everton , Guimarães Rafael Siqueira de 
Published: December 2019

O intuito deste trabalho foi pesquisar sobre o drama como método de ensino de teatro, desdobrada em uma pesquisa orientada desde a ação prática. Por meio de um traçado histórico e significativo do drama – também conhecido na Inglaterra por process drama e drama in education, analisamos uma prática em pesquisa-ação desenvolvida com professores em formação a partir de uma série de episódios concebida por meio da peça A falecida, de Nelson Rodrigues, como pré-texto. O processo analisado permitiu um olhar mais aprofundado a respeito da articulação desse método de ensino anglo-saxônico com a transversalidade proposta para o currículo brasileiro. Conceitos como experiência, formação e reprodução permeiam toda a fundamentação e análise da pesquisa, bem como aqueles conceitos próprios do drama como método de ensino.
Role clarity deficiencies can wreck agile teams
Authors: Barke Helena , Prechelt Lutz 
Published: December 2019

Background
One of the twelve agile principles is to build projects around motivated individuals and trust them to get the job done. Such agile teams must self-organize, but this involves conflict, making self-organization difficult. One area of difficulty is agreeing on everybody’s role.

Background
What dynamics arise in a self-organizing team from the negotiation of everybody’s role?

Method
We conceptualize observations from five agile teams (work observations, interviews) by Charmazian Grounded Theory Methodology.

Results
We define role as something transient and implicit, not fixed and named. The roles are characterized by the responsibilities and expectations of each team member. Every team member must understand and accept their own roles (Local role clarity) and everbody else’s roles (Team-wide role clarity). Role clarity allows a team to work smoothly and effectively and to develop its members’ skills fast. Lack of role clarity creates friction that not only hampers the day-to-day work, but also appears to lead to high employee turnover. Agile coaches are critical to create and maintain role clarity.

Conclusions
Agile teams should pay close attention to the levels of Local role clarity of each member and Team-wide role clarity overall, because role clarity deficits are highly detrimental.

We determined whether progression‐free survival (PFS) in metastatic breast cancer (MBC) patients receiving everolimus plus exemestane (EVE/EXE) varies depending on circulating tumour DNA (ctDNA) characteristics. Baseline plasma cell‐free DNA (cfDNA) from 164 postmenopausal women with ER‐positive, HER2‐negative MBC refractory to a nonsteroidal aromatase inhibitor and treated with standard EVE/EXE (Everolimus Biomarker Study, Eudract 2013‐004120‐11) was characterised for 10 relevant breast cancer genes by next‐generation sequencing with molecular barcoding. ctDNA molecule numbers, number of mutations and specific variants were related with PFS and overall survival (OS). Missense hotspot mutations in cfDNA were detected in 125 patients. The median of 54 ctDNA molecules per mL plasma distinguished patients with high and low/no ctDNA load. Patients with low/no ctDNA load (N = 102) showed longer median PFS of 5.7 months (P = 0.006) and OS of 124.8 months (P = 0.008) than patients with high ctDNA load (N = 62; 4.4 months and 107.7 months, respectively) in multivariate analyses. Patients with < 3 specific mutations (N = 135) had longer median PFS of 5.4 months compared to those with ≥ 3 mutations (3.4 months; P < 0.001). In conclusion, MBC patients with low/no ctDNA load or < 3 hotspot mutations experience longer PFS while treated with EVE/EXE.
Advances in Small and Wide‐AngleX‐Ray Scattering from Proteins and Macromolecular Solutions
Authors: Spilotros Alessandro , Gruzinov Andrey , Svergun Dmitri I. 
Published: December 2019

AbstractSmall‐angle scattering of X‐rays (SAXS) is an established method for low‐resolution structural characterization of native biological macromolecules and soft matter objets in solution. Recent progress in instrumentation (most notably, high brilliance synchrotron sources) and novel data analysis methods significantly enhanced the capabilities of the technique for the structure research. SAXS allows one to study the overall static structure and conformational changes in response to variations in external conditions or ligand binding and is able of providing structural information about partially or completely disordered systems. Extending the data collection to wide‐angle X‐ray scattering (WAXS) allows one not only to resolve the overall size and shape of proteins and complexes but also to probe the fold and to analyze subtle structural transitions. In this article, we present the basic aspects of theory and instrumentation as well as the major modeling techniques used in data analysis and interpretation of macromolecular solutions. A brief account of small‐angle neutron scattering technique (SANS) is also presented showing its complementarity to SAXS. Selected applications of SAXS and WAXS to different types of macromolecular solutions are presented including the analysis of dynamic multicomponent equilibria, characterization of flexible systems, and time‐resolved studies.
