Abstract. Organic matter production by cyanobacteria blooms is a major environmental concern for the Baltic Sea as it promotes thespread of anoxic zones. Partial pressure of carbon dioxide (pCO2) measurements carried out on Ships of Opportunity (SOOP) since 2003 have proven to be a powerful tool to resolve the carbon dynamics of the blooms in space and time. However, SOOP measurements lack the possibility to directly constrain the depth–integrated net community production (NCP) due to their restriction to the sea surface. This study tackles the resulting knowledge gap through (1) providing a best–guess NCP estimatefor an individual cyanobacteria bloom based on repeated profiling measurements of pCO2 and (2) establishing an algorithm to accurately reconstruct depth–integrated NCP from surface pCO2 observations in combination with modelled temperature profiles. Goal (1) was achieved by deploying state–of–the–art sensor technology from a small–scale sailing vessel. The low–cost and flexible platform enabled observations covering an entire bloom event that occurred in July and August 2018 in the Eastern Gotland Sea. For the biogeochemical interpretation, recorded pCO2 profiles were converted to CT*, which is the dissolved inorganic carbon concentration normalised to alkalinity. We found that the investigated Nodularia–dominated bloom event had many biogeochemical characteristics in common with blooms in previous years. In particular, it lasted for about three weeks, caused a CT* drawdown of 80 μmol kg−1, and was accompanied by a sea surface temperature increase of 10 °C. The novel finding of this study is the vertical extension of the CT* drawdown up to 12 m water depth. Integration of the CT* drawdown across this depth and correction for vertical fluxes permit a best–guess NCP estimate of ~1.2 mol–C m−2. Addressing goal (2), we combined modelled hydrographical profiles with surface pCO2 observations recorded by SOOP Finnmaid within the study area. Introducing the temperature penetration depth (TPD) as a new parameter to integrate SOOP observations across depth, we achieve a reconstructed NCP estimate that agrees to the best–guess within 10 %. Applying the TPD approach to almost two decades of surface pCO2 observations available for the Baltic Sea bears the potential to provide new insights into the control and long–term trends of cyanobacteria NCP. This understanding is key for an effective design and monitoring of conservation measures aiming at a Good Environmental Status of the Baltic Sea.
Effect of organic carbon addition on paddy soil organic carbon
decomposition under different irrigation regimes

Published: March 2021

Abstract. Anaerobic decomposition of organic carbon (OC) in submerged rice paddies is coupled to the reduction of alternative soil electron acceptors, primarily Fe3+. During reductive dissolution of Fe3+ from pedogenic oxides, previously adsorbed native soil organic carbon (SOC) could be co-released into solution. Incorporation of crop residues could hence indirectly, i.e. through the stimulation of microbially mediated Fe3+ reduction, promote the loss of native SOC via enhanced dissolution and subsequent mineralisation to CO2 and CH4. Our aim was to estimate the relevance of such a positive feedback during the degradation of added OC, and to investigate the impact of irrigation management on this mechanism and on priming effects on native SOC decomposition in general. In a six-week pot experiment with rice plants, two Bangladeshi soils with contrasting SOC-to-reducible-Fe (SOC : Feox) ratios were kept under a regime of alternate wetting and drying (AWD) or continuous flooding (CF), and were either amended with maize shoots or not. The δ13C signatures of dissolved organic C and emitted CH4 and CO2 were used to infer the decomposition of added maize shoots (δ13C = −13.0 ‰) versus native SOC (δ13C = −25.4 ‰ and −22.7 ‰). Addition of maize residues stimulated the reduction of Fe as well as the dissolution of native SOC, and the latter to a larger extent under CF, especially for the soil with the highest SOC : Feox ratio. Estimated Fe-bound SOC contents denote that stimulated SOC co-release during Fe reduction could explain this positive priming effect on SOC dissolution after the addition of maize. However, priming effects on SOC mineralisation to CO2 and CH4 were lower than for SOC dissolution, and were even negative under AWD for one soil. Enhanced reductive dissolution of Fe-bound SOC upon exogenous OC addition therefore does not necessarily lead to stimulated SOC mineralisation. In addition, AWD irrigation was found to decrease abovementioned priming effects.
Sensitivity of different BVOC emission schemes in WRF-Chem(v3.6)
to vegetation distributions and its impacts over East China

Published: March 2021

Abstract. Biogenic volatile organic compounds (BVOCs) simulated by current air quality and climate models still have large uncertainties, which can influence atmosphere chemistry and secondary pollutant formation over East China. These uncertainties are generally resulted from two sources. One is from different biogenic emission schemes coupled in model, representing for different treatments of physical and chemistry progresses during the emissions of BVOCs. The other is from the biased distribution of vegetation types over a specific region. In this study, the version of WRF-Chem updated by the University of Science and Technology of China (USTC version of WRF-Chem) from the public WRF-Chem(v3.6) is used. The modeling results over East China with different versions (v1.0, v2.0, v3.0) of Model of Emissions of Gases and Aerosols from Nature (MEGAN) in WRF-Chem are examined and documented. Sensitivity experiments with these three versions of MEGAN and two vegetation datasets are conducted to investigate the difference of three MEGAN versions in modeling biogenic VOCs and its dependence on the vegetation distributions. The experiments are also conducted for spring (April) and summer (July) to examine the seasonality of the modeling results. The results indicate that MEGANv3.0 simulates the largest amount of biogenic isoprene emissions over East China. The different performance among MEGAN versions is primarily due to their different treatments of applying emission factors and vegetation types. In particular, the results highlight the importance of considering sub-grid vegetation fraction in estimating BVOCs emissions. Among all activity factors, temperature-dependent factor dominates the seasonal change of activity factor in all three versions of MEGAN, while the different response to the leaf area index (LAI) change determines the difference among the three versions in seasonal variation of BVOC emissions. The simulated surface ozone concentration due to BVOCs can be significantly different among the experiments with three versions of MEGAN, which is mainly due to their impacts on surface VOCs and NOx concentrations. This study suggests that there is still large uncertain range in modeling BVOCs and their impacts on photochemistry and ozone production. More accurate vegetation distribution and measurements of biogenic emission flux and species concentration are needed to evaluate the model performance and reduce the uncertainties.

Abstract. Drought affects even mountain regions, despite a humid climate. Droughts' damaging character in the past and an increasing probability in future projections call for an understanding of drought impacts in the European Alpine region. The European Drought Impact Report Inventory (EDII) collects text reports on negative drought impacts. This study presents a considerably updated EDII focusing on the study region of the greater Alpine Space. This first version release of an Alpine Drought Impact Inventory (EDIIALPS) classifies impact reports into categories covering various affected sectors and enables comparisons of the drought impact characteristics. We analyzed the distribution of reported impacts on the spatial, temporal and seasonal scale, and by drought type for soil-moisture and hydrological drought. For the spatial analysis, we compared the impact data located in the Alpine Space' to entire Europe. Further, we compared impact data between different climatic and altitudinal domains (Northern vs. Southern region, pre-Alpine vs. high-altitude region), and between the Alpine countries. Compared to entire Europe, in the Alpine Space agriculture and livestock farming impacts are even more frequently reported, especially in the Southern region. Public water supply is second most relevant sector, but overall less prominent compared to Europe, especially in spring when snowmelt mitigates water shortages. Impacts occurred mostly in summer and early autumn with a delay between those impacts initiated by soil-moisture and those by hydrological drought. The high-altitude region showed this effect the strongest. From 1975 to 2020, the number of archived reports increased, with substantially more impacts noted during the drought events of 1976, 2003, 2015 and 2018. Moreover, reported impacts diversified from agricultural dominance to multi-facetted impact types covering forestry, water quality, industry and so forth. Though EDIIALPS is biased by reporting behaviour, the amount of more than 3200 compiled reports on negative drought impacts demonstrates the need to move from emergency actions to better preparedness. These may be guided by EDIIALPS' insights to regional patterns, seasons and drought types.

Abstract. To better understand snow chemistry in different environments across the
Antarctic ice sheet, we investigated snow ions on a traverse from the coast to
Dome A. Results show that the non-sea-salt (nss) fractions of K+,
Mg2+, and Ca2+ are mainly from terrestrial particle mass and nssCl− is associated with HCl. Spatially, the non-sea-salt fractions of ions to the totals are higher in the interior areas than on the coast, and seasonally, the proportions are higher in summer than in winter. Negative nssSO42- on the coast indicates
sea salts from the sea ice, and marine biogenic emissions dominate snow
SO42- in interior areas throughout the year.
Elevation-dependent trends in extreme snowfall in the French Alps
from 1959 to 2019

Published: March 2021

Abstract. Climate change projections indicate that extreme snowfall are expected to increase in cold areas, i.e. at high latitude and/or high elevation, and to decrease in warmer areas, i.e. at mid-latitude and low elevation. However, the magnitude of these contrasted patterns of change and their precise relations to elevation at the scale of a given mountain range remain ill-known. This study analyzes annual maxima of daily snowfall based on the SAFRAN reanalysis spanning the time period 1959–2019, and provided within 23 massifs in the French Alps every 300 m of elevation. We estimate temporal trends in 100-year return levels with non-stationary extreme value models that depend both on elevation and time. Specifically, for each massif and four elevation ranges (below 1000 m, 1000–2000 m, 2000–3000 m and above 3000 m), temporal trends are estimated with the best extreme value models selected on the basis of the Akaike information criterion. Our results show that a majority of trends are decreasing below 2000 m and increasing above 2000 m. Quantitatively, we find an increase of 100-year return levels between 1959 and 2019 equal to +23 % (+32 kg m−2) on average at 3500 m, and a decrease of −10 % (−7 kg m−2) on average at 500 m. However, for the four elevation ranges, we find both decreasing and increasing trends depending on location. In particular, we observe a spatially contrasted pattern, exemplified at 2500 m: 100-year return levels have decreased in the north of the French Alps while they have increased in the south which may result from interactions between the overall warming trend and circulation patterns. This study has implications for natural hazards management in mountain regions.
Tempus-A Facial Recognition Technology in Attendance Monitoring
Authors: Reynoso Melanie M. , Torres Ariane M.
Published: March 2021

Attendance monitoring has strategic importance for every organization. It has shifted from utilizing paper-based attendance monitoring to biometrics, radio-frequency identification, Bluetooth and smart technologies, Internet of Things (IoT), cloud computing, or face recognition technology. Tempus is an automated attendance monitoring system that uses face recognition technology for input, real-time IoT capabilities for processing, and portability of mobile platforms for output. It has hardware and software components. The core of the hardware component is Raspberry Pi 3, which serves as a communication medium between the camera sensor and the information system. Tempus uses Haar Cascade for facial detection and Linear Binary Pattern Histogram (LBPH) for facial recognition. The software component is further divided into two: 1) the information system for administrators, an attendance monitoring which allows encoding of data, creating new user accounts, managing schedules, recording attendance, and generating reports; and 2) mobile platform for end-users, the teachers, that is provided for communication and notification purposes only.

Emotional Intelligence and Resilience of High School Teachers in Diocesan Schools in Antique
Authors: Sencio, MSLT Florence C. , Magallanes Celo I.
Published: March 2021

In our globalized society, understanding emotions and developing resilience can help us move adeptly through the current challenges and future ones.  Emotional intelligence is the capacity of individuals to understand their emotions and those of other people.  It is an ability to label and adjust emotions appropriately, use and manage behavior and relationships, and help them adapt to environments. On the other hand, resilience refers to an individual's capacity to maintain and renew themselves, particularly in the presence of stressors; that is, they can withstand stressors without manifesting psychological dysfunction. Teaching is regarded as among the most stressful jobs today.  Knowing how to cope despite setbacks or barriers, or limited resources is a must for teachers; otherwise, they will easily quit or give up. Hence, the paper describes the level of emotional intelligence and resilience of high school teachers of a Diocesan Catholic School in Antique during the School Year 2019-2020. Additionally, it measures the differences in the level of emotional intelligence and resilience when grouped according to demographic variables. The study also explores the relationship between emotional intelligence and resilience of teachers.

Published: March 2021

El profesional en fonoaudiología identifica que la lactancia materna juega un papel determinante en la conformación estructural y funcional del sistema estomatognático; siendo la primera función que aporta información paratípica de crecimiento. Diversos autores mencionan que los movimientos de balanceo mandibular propios del amamantamiento, generan excitación sobre la articulación temporomandibular, proporcionando a la estructura estímulos paratípicos de crecimiento, generando acciones de crecimiento transversal del cráneo y la cara. Este estudio con paradigma cuantitativo, no experimental, enfocado en la búsqueda de una relación entre el tipo de lactancia o alimentación con el hábito de deglución atípica. Se utilizará como instrumento de recolección el protocolo de Evaluación Miofuncional, en sus secciones de evaluación cráneo-facial y funcional.  Los resultados se centran en el análisis de la razón de momios de la prueba de regresión logística, que evidencia la existencia de un factor protector de la lactancia materna exclusiva, donde los niños que reciben lactancia artificial tienen 4,8 veces más probabilidades de presentar deglución atípica en comparación con los que reciben lactancia materna exclusiva, y 1,6 en el grupo de lactancia materna mixta, en comparación con los de lactancia exclusiva. Los aspectos preventivos de la lactancia materna exclusiva, denotan una gran importancia como abordaje de los procesos disfuncionales y parafuncionales, teniendo como sustento una regulación de las acciones fisiológicas vinculadas en principio a la alimentación inicial, que, para llevarse a cabo, necesita de estructuras anatómicas en estado óptimo, de acciones funcionales (sensitivas y motoras) efectivas y de una guía adecuada por parte del contexto.
How nonprofits use Facebook to craft infrastructure
Authors: Hemphill Libby , Million A.J. , Erickson Ingrid
Published: March 2021

We present findings from interviews with 23 individuals affiliated with non-profit organizations (NPOs) to understand how they deploy information and communication technologies (ICTs) in their civic engagement efforts. Existing research about NPO ICT use is often critical, but we did not find evidence that NPOs fail to use tools effectively. Rather, we detail how NPOs assemble various ICTs to create infrastructures that align with their values. Overall, we find that existing theories about technology choice (e.g., task-technology fit, uses and gratifications) do not explain the assemblages NPOs describe. We argue that the infrastructures they fashion can be explained through the lens of moral economies rather than utility. Together, the rhetorics of infrastructure and moral economies capture the motivations and constraints our participants expressed and challenge how prevailing theories of ICT use describe the non-profit landscape.
Down the bot hole: Actionable insights from a one-year analysis of bot activity on Twitter
Authors: Luceri Luca , Cardoso Felipe , Giordano Silvia
Published: March 2021

Social media represent persuasive tools that have been progressively weaponized to affect beliefs, spread manipulative narratives, and sow conflicts along divergent factions. Software-controlled accounts (i.e., bots) are one of the main actors associated with manipulation campaigns, especially in a political context. Uncovering the strategies behind bots’ activities is of paramount importance to detect and curb such campaigns. In this paper, we present a long term (one year) analysis of bots activity on Twitter in the run-up to the 2018 U.S. midterm elections. We identify different classes of accounts based on their nature (human vs. bot) and engagement within the online discussion and we observe that hyperactive bots played a pivotal role in the dissemination of conspiratorial narratives, while dominating the political debate in the year before the election. Our analysis, in advance of the U.S. 2020 presidential election, reveals both alarming findings of human susceptibility to bots and actionable insights that can contribute to curbing coordinated campaigns.
Forming an affective public online: Aggressive posts and comments in the My Stealthy Freedom movement
Authors: Basmechi Farinaz , Ignatow Gabe
Published: March 2021

We use social psychology research on emotional selection of information to model how social movements use social media in the formation of affective publics and apply our model to Instagram post data from the My Stealthy Freedom anti-mandatory hijab movement in Iran. Thematic analysis applied to samples of posts and comments revealed six main themes, one of which, aggression, includes three subthemes related to verbal aggression and physical violence. As the level of aggression increased in Instagram videos, the level of aggression in the comments increased as well, and videos containing verbal aggression and physical violence had more likes and comments than did non-aggressive and non-violent videos. We discuss implications of these findings for research on social movements and the formation of affective publics.

Published: March 2021

Background - From the beginning of the SARS-CoV-2 outbreak one major issue has been the early identification of infectious cases. It is particularly challenging to perform a symptom-based screening in the paediatric population because of the seeming overlap of early clinical manifestations between Covid-19 and other common viral infections. Aims - This study was aimed to assess the likelihood that clinical scenarios driving to the SARS-CoV-2 molecular swab test (SMST) might be suggestive for Covid-19 in children. Materials and methods - A survey was proposed to the family paediatricians of the Province of Bergamo (Italy). For all the patients referred for SMST due to symptoms in the period 28/Sep/2020 - 31/Oct/2020, the request was to gather the following data: symptoms, outcome of the SMST, school level, and period between onset of symptom/s and SMST. Data were centralised in anonymous format, making use of pivot-table with aggregate data for final statistical analysis. Results - Data were exploitable for 75 family paediatricians, for a total 3,093 SMST. SMST were positive in 119 cases (3.85%). The rate of SMST positivity was: 1) higher when the interval between symptoms and SMST was shorter than 24h; 2) slightly higher at middle school vs. pre-school or elementary school. Among the observed symptoms, a robust positive association with SMST positivity was observed (OR = 7.77) with a high PPV (22.5%) only for anosmia/ageusia. Conclusion - Although this study detected a few more suggestive signs/symptoms for Covid-19 with respect to other common viral illnesses, a symptom-based screening for SARS-CoV-2 appears less effective to flush out the virus in children. The estimation of the pre-test probability should also rely on the concurrent evaluation of the epidemiological setting.

Authors: Dachraoui Maroua , Sombrero Aurora
Published: March 2021

Aim of study: To evaluate the effects of conventional tillage (CT) and no tillage (NT) systems on the soil organic carbon (SOC) changes, CO2 emissions and their relation with soil temperature and grain yield in a monoculture of irrigated maize during six years.Area of study: In Zamadueñas experimental field in the Spanish province of Valladolid, from 2011 to 2017.Material and methods: The SOC content was determined by collecting soil samples up to 30 cm in November at two years interval. Short-term CO2 emissions were measured simultaneously with soil temperature using a respiration chamber and a hand-held probe immediately before, after every tillage operation and during the maize cycle.Main results: The SOC stock of the top 30 cm soil layers was 13% greater under NT than CT. Short-term CO2 emissions were significantly higher under CT ranging from 0.8 to 3.4 g CO2 m-2 h-1 immediately after tillage while under NT system, soil CO2 fluxes were low and stable during this study period. During the first 48 h following tillage, cumulative CO2 emissions ranged from 0.6 to 2.4 Mg CO2 ha-1 and from 0.2 to 0.3 Mg CO2 ha-1 under CT and NT systems, respectively. Soil temperature did not show significant correlation with CO2 emissions; however, it depended mostly on the time of measurement.Research highlights: No tillage increased the SOC accumulation in the topsoil layer, reduced CO2 emissions without decreasing maize grain yield and minimized the impact on climate change compared to CT system.

A 67-year-old patient visited the hospital for the evaluation of pulmonary nodular lesions detected in his chest radiograph duringan annual screening. He was asymptomatic and transbronchial tumor biopsy of the nodule in the right upper lobe revealed features of pulmonary sarcoma, which did not resemble any of the histolopathological categories of primary lung cancer. A positive immunological staining for both HMB-45 and Melan-A resulted in the final diagnosis of melanoma. It is important for a respiratory clinician to remind the possibility of a melanoma, when tumors cannot be histopathologically classified under any of the categories of primary lung cancer.
De Novo Creari: Análise de manuscritos escolares por meio de tópicos de intertextualidade e criatividade

Published: March 2021

Esta pesquisa propõe a criação de metodologia própria para a análise da criatividade em manuscritos de alunos recém-alfabetizados. Foi desenvolvida uma sistematização de análise, com tópicos que permitiram comprovar como os textos considerados mais criativos são aqueles nos quais a intertextualidade tem grande influência. Para construir o estado da arte partimos dos estudos de Albuquerque (1992), Maksic e Sevkusic (2012) e Grainger, Goouch e Lambirth (2005), direcionados a produção textual na sala de aula. Delimitamos também a visão da intertextualidade, iniciada com Kristeva (1970) e tomada como critério de textualidade por Beaugrande & Dressler (1981) e Antunes (2010), além das contribuições de Bazerman (2007, 2011). Para os aspectos próprios da escritura no contexto da sala de aula adotamos os estudos sobre manuscritos escolares em Calil (2004, 2007, 2008, 2009, 2009, 2010, 2010, 2012).  Construímos nossa metodologia de intertextualidade com 4 macrocritérios e 21 subcritérios. O corpus levantado foi composto por 143 manuscritos (88 textos individuais, 48 em duplas, 7 em trio), todos coletados como resultado do projeto ‘Contos do Como e do Por que’, realizado em uma escola particular de Maceió, Alagoas. Para exemplificar a análise, nesse trabalho, foram analisados 2 textos, considerados os mais criativos, de acordo com os critérios estabelecidos pela literatura, e que atingiram maior alcance nos critérios de intertextualidade definidos na pesquisa. Os resultados apontaram a proporção de 65% de critérios de intertextualidade. As reflexões sobre os dados e sobre os resultados obtidos apontaram para a apresentação de uma proposta de definição de criatividade.

De preliminaire ontvankelijkheidsbeslissing onder de WAMCA: hoe ‘inhoudelijk’ mag de voorfase zijn?

Sinds inwerkingtreding van de WAMCA kent de collectieve actie een procedurele tweedeling in een ontvankelijkheidsfase en een inhoudelijke fase. Inhoudelijke behandeling van de vordering vindt ingevolge art. 1018c lid 5 Rv pas plaats indien en nadat de rechter over de ontvankelijkheid heeft beslist. De vraag is in hoeverre de twee fasen los van elkaar kunnen worden gezien, nu elementen van de ontvankelijkheidstoets nauw zijn verweven met de inhoudelijke beoordeling. De auteur maakt een vergelijking met de Amerikaanse federale class action, die een soortgelijke problematiek kent, en betoogt dat een genuanceerde toepassing van art. 1018c lid 5 Rv aangewezen is.

Authors: Gueye Ndeye Rokhaya , de Moissac Danielle , Kinkumba Babou , Delaquis Stéfan
Published: March 2021

Contexte. La prévalence de consommation de produits dopants chez les jeunes adultes est une préoccupation grandissante dans le champ de la santé publique, en particulier pour les autorités universitaires et sportives, les professeurs et les professionnels de la santé.

Méthodes. Un échantillon de 469 étudiants et étudiantes âgés de 18 à 24 ans ont rempli un questionnaire portant sur la consommation d’alcool et de tabac, l’utilisation des produits dopants et les motivations de cette utilisation. Des régressions logistiques multiples ont permis d’étudier les associations entre la consommation de ces produits et certaines variables socioéconomiques et académiques.

Résultats. Les trois quarts des étudiants ont consommé au moins un produit au cours de la dernière année, autre que l’alcool, pour améliorer leur performance physique ou intellectuelle. Ces produits incluent, entre autres le cannabis (25,0 %), les boissons énergisantes (38,0 %), les suppléments de protéines et de créatine (22,0 %) et les comprimés de caféine (13,0 %). Les étudiants inscrits dans une ligue de sport sont plus susceptibles de consommer de l’alcool et du cannabis que les étudiants qui ne fréquentent pas de ligues. Nous notons aussi des associations entre le groupe ethnolinguistique et la consommation d’alcool, de comprimés de caféine, de boissons énergisantes, de mélanges d’alcool et de boissons énergisantes ou d’alcool et de drogues. Les motivations associées à la consommation sont principalement la réduction du stress et le fait de rester éveillé.

Conclusion. Des stratégies de sensibilisation aux dangers de consommer de tels produits doivent être développées sur les campus des universités canadiennes selon les pratiques des étudiants de diverses origines ethnolinguistiques et auprès des populations vulnérables, tels les athlètes.
L’évaluation psychologique avec interprète : une pratique en 3 phases (l’avant — le pendant — l’après)
Authors: Burdeus-Domingo Noelia , Brisson1 Anick , Leanza Yvan
Published: March 2021

Le besoin des services d’un interprète dans le domaine de la santé pour traiter des patients allophones est, de nos jours, indiscutable. La littérature scientifique fait la démonstration de ce besoin dans toutes les spécialités médicales. En santé mentale, la situation est particulièrement sensible lorsqu’une évaluation psychologique nécessite les services d’un interprète.

Objectifs Explorer les meilleures pratiques mises en évidence par la littérature précédente pour le travail avec un interprète en santé mentale et les appliquer au contexte particulier des évaluations psychologiques.

Méthodes Une synthèse des principales recommandations fournies par la recherche pour communiquer par l’intermédiaire d’un interprète a été effectuée.

Résultats Une compilation des meilleures pratiques pour garantir une évaluation psychologique de qualité lors du travail en partenariat avec un interprète est fournie, en se concentrant sur les principales questions à prendre en compte lors de l’évaluation de patients linguistiquement et culturellement divers. Cette compilation est organisée en 3 phases : avant, pendant et après la consultation. Par exemple, la nécessité de préparer la rencontre avec l’interprète (briefing), l’impossibilité de demander une interprétation « mot à mot » (sauf dans des cas très particuliers) et la nécessité d’un débriefing avec l’interprète pour compléter l’évaluation.

Discussion Les professionnels de la santé mentale peuvent optimiser leur collaboration avec les interprètes dans l’évaluation psychologique en appliquant ce modèle en 3 phases, ce qui améliorera la communication interculturelle.
Enfant persécuteur ou enfant sauveur ? Quand trauma et migration s’amalgament à l’ambivalence de la mère dans la relation à son bébé
Authors: Mc Mahon Audrey , Feldman Marion , Rousseau Cécile , Moro Marie Rose
Published: March 2021

La grossesse est un moment de remaniements psychiques et identitaires fragile, où l’ambivalence de la mère est nécessaire et structurante pour l’enfant à venir. Mais qu’en est-il de l’ambivalence lorsque la mère est aux prises avec des traumatismes ? Quel est le rôle de la migration et de l’exil dans le fait de donner naissance dans un monde nouveau ? Quels impacts pour l’enfant et pour sa « continuité d’exister » ? C’est à la lumière de situations cliniques issues d’une recherche portant sur la transmission transgénérationnelle du trauma de la mère à l’enfant auprès de mères migrantes que ces questionnements ont surgi et que leur approfondissement s’est imposé comme une réponse à une réalité clinique souvent rencontrée en périnatalité auprès des populations immigrantes et réfugiées. L’acte de transmettre la vie prend racine dans l’histoire des mères et vient questionner leurs identités, leurs filiations et leurs affiliations mises à l’épreuve par l’adversité rencontrée. L’arrivée des enfants est à la fois fragilisante et source de « résilience » exceptionnelle. Il est donc essentiel de penser la question de l’accueil de ces dyades mère-bébé pour des soins adaptés et culturellement sensibles.

El pasado domingo día 23 de febrero se emitió en La Sexta el falso documental Operación Palace, dirigido por el periodista Jordi Évole, que proponía que el golpe de estado que tuvo lugar el 23 de febrero de 1981 en el Congreso fue un montaje. Se presenta como una trama organizada por los políticos que tiene por objetivo garantizar la estabilidad de la reciente y débil democracia y legitimar el papel del Rey como jefe del Estado.
¿Qué hace y quién es el nuevo profesional de la información?
Authors: Garcia Alsina Montserrat
Published: March 2021

Hace años que hablamos sobre la necesidad de que el mercado laboral y los empleadores conozcan qué pueden y saben hacer los profesionales de la información. Bajo esta denominación empleamos diferentes etiquetas profesionales. Esto puede tener efectos perjudiciales en el momento en que una empresa e incluso un organismo público tenga que contratar a un profesional de la información. El departamento de recursos humanos, cuando redacte una oferta de trabajo, puede tener problemas para identificar qué perfil profesional y qué titulación hay detrás.
Sara y la biblioteca que nunca existió
Authors: Sanz Martos Sandra
Published: March 2021

El pasado 24 de octubre celebramos el Día Internacional de las bibliotecas. Mensajes en las redes sociales, actividades enfocadas al público infantil y juvenil en su mayoría, reuniones extraordinarias de los clubes de lectura, fueron algunas de las maneras de celebrarlo. Pero también hubo actividades donde se evidenció la situación de precariedad por la que atraviesan muchas de ellas. E incluso se señaló con preocupación la posibilidad de que algunas acabaran cerrando. Sirva este pequeño relato, que vais a leer a continuación, como pequeño homenaje y reflexión sobre lo que empieza a ser más que una terrible amenaza.
A Case Series on Neurological Insights of Scrub Typhus
Authors: Saxena Puneet , Chadha Deepak , Goyal Rishika
Published: March 2021

Scrub typhus is a rickettsial disease caused by gram negative coccobacilli and transmitted through the bite of larval stage of mite. The disease is notable in the Asia-Pacific belt with few sporadic and epidemic cases reported from India as well. The disease is well identified from North Western part of Rajasthan that are the areas with dense vegetation. The clinical scenario ranges from acute febrile illness to multiple organ dysfunction by virtue of haematogenous seedling. This case series highlights the neurological manifestations of scrub typhus that are diverse and life threatening but holding dearth of literature to convoy appropriately timed diagnosis and treatment.

Authors: Ikpeazu O. V. , Ezeja M. I. , Igwe K. K.
Published: March 2021

Aims: To investigate the anti-inflammatory activity of Picralima nitida stem bark methanol extract (PNSBE).

Study Design: The study was carried out using in vivo (carrageenan-induced paw oedema and egg albumin-induced paw oedema) and in vitro (Human red blood cell (HRBC) membrane stabilization assay) models in rat.

Place and Duration of Study: Department of Veterinary Physiology and Pharmacology, Michael Okpara University of Agriculture, Umudike, Abia State, Nigeria from March to July, 2020.

Methodology: The extract was used at the doses of 100, 200 and 400 mg/kg while diclofenac (20 mg/kg) was used as the standard reference drug for the in vivo study (carrageenan-induced paw oedema and egg albumin). For the in vitro study (red blood cell haemolysis), the extract was used at the concentrations of 25, 50, 100, 200 and 400 µg/ml while diclofenac 250 µg/ml was used.

Results: In the carrageenan-induced paw oedema model, the extract at the doses used and the reference drug significantly (p < 0.05) reduced the paw edema in the rats at 1 hour in a dose dependent manner. Also, in the egg albumin model, the paw oedema of treated rats was significantly (P < 0.05) reduced by PNSBE dose dependently reducing the mean rat paw oedema from 0.99 ± 0.12 to 0.61 ± 0.06 at the first hour. There was also a concentration dependent inhibition of red blood cell haemolysis by the extract in the HRBC membrane stabilization assay.

Conclusion: Picralma nitida demonstrated a significant anti-inflammatory activity in this study.
Status of Zinc Availability in Jhum Fields under Rainfed Condition in Zunheboto District of Nagaland
Authors: Sentimenla .
Published: March 2021

The Zinc deficiency in the soil is spreading worldwide. It can lead to decrease in soil fertility, crop yield and productivity. It is an essential micronutrient required for plants and an important dietary nutrient for the wellbeing of human beings and animals. In Nagaland, its deficiency is slowly increasing and several factors such as shifting cultivation which is also known as slash and burn, forest fire, leaching and runoff and nutrient exhaustion in the soil by the crop may be attributing to its deficiency in the soil. As Zinc deficiency is rapidly increasing all over, a soil survey on zinc availability was conducted in 83 jhum fields under rainfed condition covering 7 villages of  Zunheboto district of Nagaland during 2016-17. The soil samples were collected from the field using GPS and were analysed using standard procedure. It was observed that the Zinc deficiency ranged from 0.26 to 0.55 mg kg-1 which indicated that its deficiency is found widespread in this part of the region. Zinc being an important micronutrient for growth and yield of crops, timely nutrient management through balanced fertilization will enhance soil fertility and crop productivity.
Nutrient Composition of Locally Available Browses Consumed by Matschie’s Tree Kangaroos (Dendrolagus matchiei) in Six North American Zoological Facilities
Authors: Dierenfeld Ellen S. , Bezjian Marisa , Dabek Lisa
Published: March 2021

Locally collected browses (n=17 spp.) consumed by Matschie’s tree kangaroos (Dendrolagus matschiei) in 6 North American zoological institutions were analyzed for comparison with native plants eaten by this species in Papua New Guinea to evaluate dietary suitability.  Primary nutrients including crude protein and fat, fiber, starch, non-fiber carbohydrates, and ash were determined using standard analytical methods for forages.  Macrominerals calcium (Ca), phosphorus (P), magnesium (Mg), potassium (K), sodium (Na) and sulfur (S), as well as trace elements copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo) and zinc (Zn) were quantified in leaf (n=18), flower (n=1), twig (n=9) and bark (n=6)   samples.  Tannin content was estimated through the bovine serum albumin methodology.  On a dry matter basis (DMB) , foods averaged (± SD) moderate protein (12 ± 5%) and soluble carbohydrate (27 ± 12%) content, along with low starch (1 ± 1%) and crude fat (3 ± 2%) values, and moderate to high values in fiber fractions (neutral detergent fiber 49 ± 15%, acid detergent fiber 33 ± 13%, lignin 11 ± 5%). Macromineral concentrations (Ca 2.2 ± 1.6%, P 0.2 ± 0.1%, Mg 0.3 ± 0.2%, K 1.5 ± 0.6%, Na 0.03 ± 0.04%, S 1.2 ± 1%) and select trace minerals were within anticipated ranges (Cu 11 ± 5 mg/kg, Mo 1 ± 1 mg/kg and Zn 33 ± 18 mg/kg); exceptions Fe (122 ± 11 mg/kg) and Mn (51 ± 81 mg/kg) were considered on the high end of dietary adequacy for most herbivores. Leaves differed significantly from woody parts for all proximate nutrients, as well as K, S, Fe, and tannin content.  Consumed in a 50:50 DMB ratio, locally available browses provide similar nutrient profiles as plants eaten by free-living tree kangaroos.  Combined data provide  information useful in establishing nutrient targets for dietary development, leading to improved health, welfare, and feeding management of tree kangaroo populations under human care.
