Abstract. Recent advancements in catchment hydrology (such as understanding catchment
similarity, accessing new data sources, and refining methods for parameter
constraints) make it possible to apply catchment models for ungauged basins
over large domains. Here we present a cutting-edge case study applying
catchment-modelling techniques with evaluation against river flow at the
global scale for the first time. The modelling procedure was challenging but
doable, and even the first model version showed better performance than
traditional gridded global models of river flow. We used the open-source
code of the HYPE model and applied it for >130 000 catchments
(with an average resolution of 1000 km2), delineated to cover the
Earth's landmass (except Antarctica). The catchments were characterized using
20 open databases on physiographical variables, to account for spatial and
temporal variability of the global freshwater resources, based on exchange
with the atmosphere (e.g. precipitation and evapotranspiration) and related
budgets in all compartments of the land (e.g. soil, rivers, lakes, glaciers,
and floodplains), including water stocks, residence times, and the pathways
between various compartments. Global parameter values were estimated using a
stepwise approach for groups of parameters regulating specific processes and
catchment characteristics in representative gauged catchments. Daily and
monthly time series (>10 years) from 5338 gauges of river flow
across the globe were used for model evaluation (half for calibration and
half for independent validation), resulting in a median monthly KGE of 0.4.
However, the World-Wide HYPE (WWH) model shows large variation in model
performance, both between geographical domains and between various flow
signatures. The model performs best (KGE >0.6) in the eastern USA,
Europe, South-East Asia, and Japan, as well as in parts of Russia, Canada,
and South America. The model shows overall good potential to capture flow
signatures of monthly high flows, spatial variability of high flows,
duration of low flows, and constancy of daily flow. Nevertheless, there
remains large potential for model improvements, and we suggest both redoing
the parameter estimation and reconsidering parts of the model structure for
the next WWH version. This first model version clearly indicates challenges
in large-scale modelling, usefulness of open data, and current gaps in
process understanding. However, we also found that catchment modelling
techniques can contribute to advance global hydrological predictions.
Setting up a global catchment model has to be a long-term commitment as it
demands many iterations; this paper shows a first version, which will be
subjected to continuous model refinements in the future. WWH is
currently shared with regional/local modellers to appreciate local
knowledge.

The purpose of this study was to investigate the larvicidal activity of Pterodon polygalaeflorus oil extract against the mosquito vector Aedes aegypti. For this, crushed P. polygalaeflorus fruit underwent solvent extraction to obtain the oil extract. The chemical characterization was performed by gas chromatography coupled to mass spectrometry. For the bioassays third instar larvae of Ae. aegypti were utilized. Tests were carried out to determine the larvicidal activity and the residual effect under laboratory conditions, as well as field screening (small scale).The major components of P. polygalaeflorus oil extract were, respectively, E-caryophyllene, germacrene D and bicyclogermacrene. Lethal concentrations of 50% and 90% were 36.5 and 64.8 μg/mL respectively. The solution presented a residual effect for seven days and the efficiency of the product was preserved under field conditions. The results encourage continuing studies with the oil extract of P. polygalaeflorus as a research target for bioinsecticides.KEY WORDS: Bioinsecticide; sucupira; terpenes; vector control.

The purpose of this investigation was to determine the occurrence of head lice in long-term care facilities (LTCFs) in Uberlandia, MG, Brazil, analyze associations with sex, ethnicity, age and hair characteristics, and verify awareness among elderly adults. Head inspections were performed and infestation was characterized on individual forms. A questionnaire on the biology, epidemiology and control of head lice was applied. Overall occurrence was 1.4%, being highest in elderly women with medium-length curly hair. Questionnaire responses indicated that the majority had no general knowledge on head lice. More than 40% reported infestation at some point in their lives and most knew how to control it. Overall occurrence was considered low and is related to measures adopted by the LTCFs, which controlled infestation by minimizing the influence of factors normally associated with its occurrence. The study was pioneer in analyzing associations between head lice and the degree of autonomy of elderly adults.KEY WORDS: Head lice; infestation; elderly adults; Uberlandia, MG.

On the contributions of non-technical stakeholders to describing UX requirements by applying proto-persona
Authors: Pinheiro Eduardo G , Lopes Larissa A. , Conte Tayana U. , Zaina Luciana A M 
Published: February 2020

Context: Requirements elicitation is a software development phase that should investigate both functional and user experience (UX) requirements. Proto-persona is a technique that encourages the attention on the needs of a group of users. Usually, its elaboration is conducted by software specialists, technical stakeholders. However, non-technical stakeholders usually know more about target users and frequently do not take part in proto-persona elaboration. Objective: This work has the goal of investigating the contribution of non-technical stakeholders in the specification of UX requirements by using the proto-persona technique. For this, we explored the construction of the proto-personas and the use of these to the prototyping of solutions. Method: We carried out an empirical study in two rounds from which we analyzed and compared the contribution that technical and non-technical stakeholders had on the specification of UX requirements. In the first, 8 non-technical and 5 technical stakeholders built proto-personas. Afterwards, 18 pairs of software developers created low fidelity prototypes by using the information of proto-personas.~For the two rounds, we conducted a qualitative analysis exploring which UX requirements were described and used. Results: Our results revealed that both stakeholders have written up details of UX requirements on the artifact, however, throughout different and complementary perspectives. We also could observe that proto-personas produced by both were used on the prototyping activity. Conclusion: Our paper contributed to demonstrate that non-technical stakeholders were able to contribute to the specification of UX requirements and that proto-persona can boost such activity.
Giant Cell Arteritis: Current Advances in Pathogenesis and Treatment
Authors: A. Dagostin Marília , M.R. Pereira Rosa 
Published: February 2020

Giant cell arteritis (GCA) is the most common vasculitis in adults, with the incidence increasing with the advancing age. The aorta and its branches, especially the carotid extracranial branches, are the classic targets of inflammation in GCA. Visual loss, upper limb ischemia, and stroke are complications described. Suspicion of GCA is a medical emergency, and patients need to be quickly diagnosed/treated to prevent irreversible damage. Headache is the most common symptom, and a new-onset headache in older adults should always raise the suspicion of GCA. Patients may also present with scalp tenderness or tongue/jaw pain. GCA is often found to be the cause of an obscure-origin fever in older patients. A positive temporal artery biopsy is considered the gold standard for the diagnosis, but imaging techniques enable the assessment of cranial and extracranial arteries and the aorta. Ultrasound of temporal arteries is recommended and noncompressible “halo” sign is the typical finding. PET, MRI, or CT may be useful for the detection of the disease in the aorta and other vessels. The treatment must be started promptly with prednisone 1 mg/kg/day. When visual symptoms/unilateral visual loss is present, methylprednisolone pulse is recommended. Methotrexate, leflunomide and tocilizumab may be effective and well-tolerated glucocorticoid-sparing agents in GCA. Cardiovascular diseases are the leading causes of death in patients.

Les majorités nationales ont-elles une couleur ?
Authors: Eid Paul 
Published: February 2020

J’examine ici la pertinence de la catégorie de « blanchité » pour l’analyse du racisme en Occident. Cette catégorie, travaillée par lesWhiteness Studies, a l’avantage de rendre visibles les mécanismes systémiques garantissant aux « BlancHEs » un accès privilégié au pouvoir et aux ressources. Je ferai valoir notamment que les vives résistances suscitées au Québec par la notion de racisme systémique fut un révélateur d’une certaine « fragilité blanche » qui se manifeste, typiquement, lorsque le rôle et les intérêts des « racisantEs » dans la reproduction des rapports sociaux de « race » sont nommés et rendus visibles. Toutefois, aussi utile soit-il pour l’étude du racisme, l’usage sociologique de la notion de blanchité commande certaines précautions, afin de la complexifier et de la dégager des cadres essentialisants à travers lesquels elle est encore trop souvent appréhendée au sein desWhiteness Studies. Je soutiendrai en outre qu’on ne peut penser la blanchité sans réfléchir conjointement au processus de construction de la nation et de ses étrangers intérieurs. Par ailleurs, l’expérience de la blanchité varie en fonction des rapports mutuellement structurants entre la « race » et d’autres facteurs de différenciation sociale (ex. : genre, classe).
Dans l’arrière-boutique : parcours professionnels et résidentiels de petits commerçants montréalais
Authors: Maltais Alexandre 
Published: February 2020

S’appuyant sur une enquête de terrain réalisée dans deux quartiers centraux montréalais en transition socioéconomique — Hochelaga-Maisonneuve et Saint-Henri—Petite-Bourgogne —, cet article propose de suivre l’évolution récente du petit commerce à partir du vécu des commerçants. Il mobilise un corpus de 50 entretiens semi-directifs réalisés auprès de propriétaires d’établissements commerciaux de ces deux quartiers. L’analyse de ces entretiens permet, dans un premier temps, de faire ressortir la diversité des profils des commerçants en proposant une typologie de leur rapport au commerce tenant compte de leur position dans le cycle de vie, de leur situation familiale et de leur trajectoire professionnelle passée. Elle permet ensuite, dans un second temps, d’examiner leur rapport au quartier où ils tiennent boutique, en insistant sur les représentations antérieures et postérieures à leur établissement. Nous constatons ainsi que les trajectoires professionnelles et résidentielles des nouveaux commerçants sont mues par des considérations éthiques et esthétiques fortes, les rattachant plus nettement aux couches moyennes salariées dont plusieurs d’entre eux sont issus qu’à la petite bourgeoisie commerçante d’hier.

Genome-wide identification and characterization of the soybean SOD family during alkaline stress
Authors: Lu Wenxiu , Duanmu Huizi , Qiao Yanhua , Jin Xiaoxia , Yu Yang , Yu Lijie , Chen Chao 
Published: February 2020

Background
Superoxide dismutase (SOD) proteins, as one kind of the antioxidant enzymes, play critical roles in plant response to various environment stresses. Even though its functions in the oxidative stress were very well characterized, the roles of SOD family genes in regulating alkaline stress response are not fully reported.

Methods
We identified the potential family members by using Hidden Markov model and soybean genome database. The neighbor-joining phylogenetic tree and exon-intron structures were generated by using software MEGA 5.0 and GSDS online server, respectively. Furthermore, the conserved motifs were analyzed by MEME online server. The syntenic analysis was conducted using Circos-0.69. Additionally, the expression levels of soybean SOD genes under alkaline stress were identified by qRT-PCR.

Results
In this study, we identified 13 potential SOD genes in soybean genome. Phylogenetic analysis suggested that SOD genes could be classified into three subfamilies, including MnSODs (GmMSD1–2), FeSODs (GmFSD1–5) and Cu/ZnSODs (GmCSD1–6). We further investigated the gene structure, chromosomal locations and gene-duplication, conserved domains and promoter cis-elements of the soybean SOD genes. We also explored the expression profiles of soybean SOD genes in different tissues and alkaline, salt and cold stresses, based on the transcriptome data. In addition, we detected their expression patterns in roots and leaves by qRT-PCR under alkaline stress, and found that different SOD subfamily genes may play different roles in response to alkaline stress. These results also confirmed the hypothesis that the great evolutionary divergence may contribute to the potential functional diversity in soybean SOD genes. Taken together, we established a foundation for further functional characterization of soybean SOD genes in response to alkaline stress in the future.
Niche differentiation in the rhizosphere and endosphere fungal microbiome of wild Paris polyphylla Sm.

Published: February 2020

Background
The plant microbiome is one of the key determinants of plant health and metabolite production. The plant microbiome affects the plant’s absorption of nutrient elements, improves plant tolerance to negative environmental factors, increases the accumulation of active components, and alters tissue texture. The microbial community is also important for the accumulation of secondary metabolites by plants. However, there are few studies on the niche differentiation of endophytic microorganisms of plants, especially at different elevations.

Methods
We investigated the effects of altitude on the community composition of endophytic fungal communities and the differentiation of endophytic microorganisms among different niches in Paris polyphylla Sm. The rhizosphere soil, roots, rhizomes and leaves of wild-type P. polyphylla Sm. at different altitudes were sampled, and the fungal communities of all samples were analyzed by internal transcribed spacer one amplification sequencing.

Results
The results showed that in rhizosphere soil, the number of operational taxonomic units (OTUs) that could be classified or identified decreased significantly with increasing altitude, whereas in the endosphere of plants, the total number of OTUs was higher at intermediate altitudes than other altitudes. Furthermore, the structural variability in the rhizosphere fungal community was significantly lower than that in the endophytic communities. In addition, our results confirmed the presence of niche differentiation among members of the endophytic microbial community. Finally, we also determined that the predominant genus of mycobiota in the rhizome was Cadophora. This study provides insight into the relationships between the endosphere microbiome and plants and can guide the artificial cultivation of this plant.
Does size matter? Morphometrics of southern bent-winged bats (Miniopterus orianae bassanii) and eastern bent-winged bats (Miniopterus orianae oceanensis)
Authors: Holz Peter H. , Lumsden Lindy F. , Reardon Terry , Gray Paul , Hufschmid Jasmin 
Published: February 2020

ABSTRACT
The population size of the southern bent-winged bat, a critically endangered bat subspecies, has significantly declined in the last 50 years. As part of a larger study to determine whether disease could be a contributing factor to this decline, morphometric data was gathered for southern bent-winged bats and compared with the more common eastern bent-winged bats. Southern bent-winged bats were heavier, but forearm length was not significantly different between the two subspecies. This suggests that southern bent-winged bats may require more energy to fly and forage than eastern bent-winged bats. Consequently, southern bent-winged bats may need to consume more food on a daily basis, potentially increasing their susceptibility to adverse conditions such as drought.
The Chemistry of Multibonded Organoboron Compounds
Authors: Devillard Marc , Alcaraz Gilles 
Published: February 2020

AbstractMultiply bonded boron species are fascinating objects of study addressing concerns about the chemical bonding. Although mostly exemplified with light p‐block elements, the use of Group 6–10 transition metals as models to more clearly understand and rationalize the bonding in this family of compounds has also proved successful. In this prospect, the interplay between experiment and theory pushes forward the frontiers of the analysis based on the metric parameters, and it clearly appears that the notion of doubly or triply bonded boron in such species must be qualified. The bond orders are more often partial involving more or less polarized bonds responsible for the chemical reactivity. These features are developed in this chapter starting with the nearest neighbors of boron and finishing with the case of transition metals.
