Study of the academic production on communication in Spain and Latin America
Authors: Piñeiro-Naval Valeriano , Morais Ricardo
Published: July 2019

This paper approaches the state of academic production in communication confined to the Hispanic sphere, namely, Spain and Latin America, during the period extending between 2013 and 2017. As in previous meta-research, the aim here is to highlight potential shortcomings in the discipline, both theoretically and methodologically. From an instrumental standpoint, a systematic, objective and quantitative content analysis was implemented on a probabilistic sample of 1,548 articles from the seven main journals in the field, all indexed in the first quartiles of the SJR-Scopus ranking. Aside from the percentage report for each variable, two-stage cluster analyses were performed twice to identify statistically significant publication patterns. As far as the results are concerned, it is worth highlighting the empirical nature of the studies, generally relying on quantitative methodologies, although no specific theoretical corpora are referenced. On the other hand, and although social networks and ICTs have gained a notable prominence, traditional media continue to be, collectively, the most prominent in communication research. Finally, the challenges of the field seem to revolve around two axes: providing studies with methodological robustness and, above all, with the theoretical background necessary to confront, with guarantees, the understanding of the liquid communicative manifestations that flow, at great speed, from the Information Society.

El presente trabajo aborda el estado de la producción académica en comunicación circunscrita al ámbito hispánico en España e Hispanoamérica durante el período que transcurre de 2013 a 2017. Al igual que en otras metainvestigaciones precedentes, el objetivo aquí radica en poner de manifiesto las posibles carencias de la disciplina, tanto a nivel teórico como metodológico. Desde un punto de vista instrumental, se implementó un análisis de contenido sistemático, objetivo y cuantitativo sobre una muestra probabilística de 1.548 artículos pertenecientes a las siete principales revistas del área, todas ellas indexadas en los primeros cuartiles del ranking SJR-Scopus. Además del reporte porcentual de cada variable, se ejecutaron dos análisis de conglomerados bietápicos para identificar patrones de publicación estadísticamente significativos. En lo que a los resultados respecta, cabe destacar el cariz empírico de los trabajos, apoyados habitualmente en metodologías cuantitativas, aunque sin hacer alusión a corpus teóricos concretos. Por otro lado, y si bien las redes sociales y las TIC han cobrado un notable protagonismo, los medios tradicionales continúan siendo, de manera agregada, los de mayor relieve en la investigación en comunicación. Finalmente, los desafíos del área parece que girarán en torno a dos ejes: nutrir a los estudios de la robustez metodológica y, muy en especial, del acervo teórico necesarios para afrontar, con garantías, la comprensión de las líquidas manifestaciones comunicativas que manan, a gran velocidad, de la Sociedad de la Información.
Foliage est-il à leaves ce que jewellery est à jewels ? Etude de rapports entre dénombrables au pluriel et indénombrables singuliers
Authors: Gardelle Laure
Published: July 2019

Les recherches sur les noms qui dénotent des pluralités d’unités ont isolé les noms d’agrégats hétérogènes (ainsi jewellery ou furniture). Le présent article cherche à établir s’il faut également considérer comme « noms d’agrégats » des cas passés sous silence tels que foliage, c’est-à-dire des noms au fonctionnement indénombrable eux aussi, mais qui ne s’appliquent pas à des unités hétérogènes, et ne sont donc pas hyperonymiques (au moins dans leur sens central). L’étude conclut que l’hétérogénéité n’est pas un trait définitoire des noms d’agrégats, et qu’il faut y inclure les noms de type foliage. Comme les autres indénombrables étudiés ici, ils présentent une conceptualisation qui fait des unités des parties d’un tout (à la différence des « regroupements » opérés par les N + ‑s, qui dénotent des unités rédupliquées, dont on peut constater les différences, et dont on peut accéder aux parties), et diffèrent des « collectifs », dénombrables, en ce qu’ils ne permettent pas d’attribuer une propriété distributive au tout (heart-shaped foliage / jewellery ne peut par exemple s’appliquer qu’aux feuilles et bijoux individuels). Comme les noms d’agrégats hétérogènes, les noms de type foliage trouvent leur raison d’être dans la mise en avant d’une fonctionnalité commune, au détriment des individualités.Les noms de type foliage présentent une grande différence avec les noms d’agrégats hétérogènes, au-delà de l’absence d’hétérogénéité : les unités sont conceptualisées comme étant fixées à un support (typiquement, une ou des branche(s) pour foliage). Ceci explique que a piece of foliage ne puisse désigner une feuille, alors que a piece of jewellery désigne un bijou. Mais là encore, on conclut que cette différence ne remet pas en cause l’appartenance des noms de type foliage à la classe des noms d’agrégats ; de la même manière, la classe des noms collectifs montre une grande diversité de comportements et de conceptualisations.
Question d'honneur
Authors: Jacotot Mathieu
Published: July 2019

Est-il légitime d'employer la notion moderne d'« honneur » à propos de la République romaine antique ? Les Romains de cette époque obéissaient-ils à un code de conduite strict ? Sur quoi fondaient-ils le prestige social ? Quelles marques de distinction employaient-ils et à quelles fins ? Telles sont quelques-unes des questions auxquelles cet ouvrage tente de répondre. Pour ce faire, l'auteur analyse trois notions romaines, honos, honestum et honestas, qui recouvrent des objets socio-politiques (marques d'honneur, prestige, charges publiques) et des données morales (dignité de la conduite, bien éthique). Cette diversité est appréhendée dans l'ouvrage par une approche plurielle, relevant de la sémantique, de la sociologie et de l'histoire des idées. L'étude préalable du sens de ces termes dans les textes latins débouche ainsi sur l'examen des pratiques d'hommage et d'honorabilité dans la vie des Romains. Confrontant ensuite la pratique à la théorie, l'ouvrage étudie la manière dont ces trois notions ont été employées comme thèmes littéraires, instruments idéologiques et concepts philosophiques chez les auteurs latins de la République.
Les dieux olympiens et la mer
Authors: Fenet Annick
Published: July 2019

Si l'affirmation selon laquelle les Grecs sont un peuple de marins peut être nuancée, il est cependant indéniable que la mer représente un aspect géographique majeur du monde grec antique. Il n'est donc guère surprenant que cet élément ait imprégné les croyances et les cultes, et ce depuis l'Atlantique jusqu'au golfe Persique et particulièrement en Grande Grèce. Cet ouvrage explore ainsi les manières dont la culture maritime a influé sur les figures majeures du panthéon grec, les divinités olympiennes, depuis Homère jusqu'à la fin de l'époque hellénistique. Il tempère à cet égard l'importance accordée trop souvent a priori à Poséidon. Toutes les sources ont été requises dans une telle enquête : littéraires, épigraphiques, archéologiques, iconographiques, numismatiques. Par l'analyse des croyances, de la topographie des sanctuaires, des pratiques cultuelles tant à bord qu'à terre et des ex-voto maritimes (ancres et bateaux), il constitue un outil indispensable pour l'étude de la religion grecque comme pour celle de l'archéologie navale.
Assessment of Tribological Properties of Low Friction Thin Layers Produced by Vacuum Methods
Authors: Paradecka Agnieszka , Lukaszkowicz Krzysztof , Sondor Jozef
Published: July 2019

Low friction thin layers are an excellent alternative for conventional coatings. They provide increased life of the elements, to which they were applied, due to enhancing the hardness or chemical and electrochemical resistance. They help to avoid the cracks, oxidation, as well as possible structural changes during the element's work. However, they primarily improve tribological properties by increasing wear resistance and reducing the friction. This also applies to components operating under variable conditions such as load, speed, temperature. The presented article analyzes the properties of various low-friction thin layers deposited by vacuum methods on the steel substrates. DLC, TiC, MoS2, CrCN thin layers were chosen, as they achieve the lowest possible coefficient of friction. In the framework of this work the measurements of adhesion of the investigated layers to the substrate as well as the friction coefficient, chemical analysis, microstructure and topographic analysis of the low-friction layers were carried out.

γδ T Cell Update: Adaptate Orchestrators of Immune Surveillance
Authors: Hayday Adrian C.
Published: July 2019

As interest in γδ T cells grows rapidly, what key points are emerging, and where is caution warranted? γδ T cells fulfill critical functions, as reflected in associations with vaccine responsiveness and cancer survival in humans and ever more phenotypes of γδ T cell–deficient mice, including basic physiological deficiencies. Such phenotypes reflect activities of distinct γδ T cell subsets, whose origins offer interesting insights into lymphocyte development but whose variable evolutionary conservation can obfuscate translation of knowledge from mice to humans. By contrast, an emerging and conserved feature of γδ T cells is their “adaptate” biology: an integration of adaptive clonally-restricted specificities, innate tissue-sensing, and unconventional recall responses that collectively strengthen host resistance to myriad challenges. Central to adaptate biology are butyrophilins and other γδ cell regulators, the study of which should greatly enhance our understanding of tissue immunogenicity and immunosurveillance and guide intensifying clinical interest in γδ cells and other unconventional lymphocytes.

Although out-of-hospital cardiac arrests (OHCA) are a major cause of mortality internationally, data regarding survival in Greece remains scarce and inconclusive. The aim of this study is to assess the immediate and 24-hour survival of OHCA sufferers during a 5-year period in a public hospital in Athens. A retrospective study was conducted on all cardiac arrests that were transferred to our hospital during a five-year period (2011-2015). Our primary objective was to calculate return of spontaneous circulation (ROSC) and 24-hour survival ratios. Our secondary objective was to estimate 30-day survival. Demographic data was also collected. 283 OHCA were included in the study. The mean age was 67.2 years and the male: female ratio was 2. Medical history was available for 33.6% of patients. 72.1% of cases were transferred to the emergency department by ambulance and 2.8% by private means of transport. Cardiopulmonary resuscitation was attempted on 57.6% of cardiac arrests, 8.6% regained ROSC and 6.1% survived for 24 hours. The 30-day survival was expected to be less than 3.5%. In our institution, ROSC, 24-hour and expected 30-day survival were lower than the European average and in accordance with the recent prospective Eureca One study. However, data from our institution cannot be generalised and multicenter studies are required in order to clarify OHCA outcomes in Greece.

Authors: Prabhakar Anuj , Khandelwal Niranjan , Vyas Sameer , Gupta Vivek , Kharbanda Parampreet S , Mohanty Manju
Published: July 2019

Aims: To evaluate the role of functional magnetic resonance imaging (fMRI) in epilepsy management and to ascertain whether laterality index (LI) derived from fMRI data, using routinely utilized paradigms, can serve as an adjunct to/or replace preoperative neuropsychological testing for evaluation of language lateralization and impairment. Materials and Methods: This was a prospective study which included 20 consecutive patients with a clinical diagnosis of temporal lobe epilepsy over a period of 1 year. Neuropsychological assessment included oral word association test and animal names test. The scores of both tests were compared with normographic data provided in the NIMHANS neuropsychology battery. Three fMRI paradigms were used, namely, picture naming, word generation, and sentence completion. Processing and statistical analysis were performed subsequently. Results and Conclusion: Right temporal lobe epilepsy (RTLE) was seen in 12 patients and left temporal lobe epilepsy (LTLE) in 8 patients. All patients were right handed. The activation pattern was predominantly left lateralized. Language lateralization varied with the type of paradigm. The overall percentage of patients showing left lateralization ranged from 44.00% for the picture naming task to 75% for the sentence completion. Reduced left lateralization was noted in both LTLE and RTLE patients. A negative correlation was observed in LTLE patients between performance in the verbal fluency and the lateralization index in the temporal and parietal regions of interest (ROI) in the word generation paradigm, suggesting that increased left lateralization was associated with a poorer score on neuropsychological tests. In RTLE patients, however, there was no significant correlation between performance in neuropsychological tests and LI. In conclusion, language lateralization using LI can serve as an adjunct during preoperative evaluation. However, it cannot replace neuropsychological testing.
Endovascular treatment of refractory iatrogenic femoral artery pseudoaneurysm using Amplatzer vascular plugs following unsuccessful retrograde Angio-Seal deployment
Authors: Loh Eu Jhin , Allen Robert
Published: July 2019

Iatrogenic common femoral artery pseudoaneurysm is a well-known vascular access complication of angiography and transfemoral intervention. Thrombin injection is a well-accepted technique in treating these pseudoaneurysms but possess a significant risk of distal lower extremity thrombosis leading to severe consequences. Several case reports described the novel approach to closing these pseudoaneurysms via a retrograde deployment of an Angio-Seal vascular closure device. We describe a case of a successful treatment of refractory iatrogenic femoral artery pseudoaneurysm using Amplatzer vascular plugs following unsuccessful retrograde deployment of an Angio-Seal vascular closure device.

Published: July 2019

Gastrointestinal stromal tumor (GIST) are the most common non epithelial tumor of the gastrointestinal (GI) tract. They arise from interstitial cells of Cajal present in the myenteric plexus. They can also arise outside the GI tract from mesentery, retro peritoneum and omentum. With the advent of new targeted molecular therapy c- tyrosine kinase inhibitor (Imatinib), it has become important to differentiate between response and pseudo-progression of the disease as response evaluation criteria for GIST are different from Response Evaluation Criteria in Solid Tumors (RECIST). Purpose of this pictorial essay is to enumerate the characteristic CT features of GIST, and discuss atypical features and response evaluation criteria.

Purpose: To evaluate the role of diffusion-weighted magnetic resonance imaging (DW-MRI) in the detection of residual malignant tumor of hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE) with drug-eluting beads (DEBs). Subjects and Methods: Pre-contrast T1, T2, dynamic contrast–enhanced, and respiratory-triggered DW-MRI (b factor 0, 400, and 800 s/mm2) were obtained in 60 patients with HCC who underwent tran-sarterial hepatic chemoembolization with DEBs. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for the DW imaging images. Apparent diffusion coefficients (ADCs) were calculated searching for the optimal cut-off value using the receiver operating characteristic (ROC) curve. Results: DW-MRI had a sensitivity of 77.1%, a specificity of 60.7%, a PPV of 71.05%, and a NPV of 68%. The difference between the malignant and benign groups’ ADC variables was statistically significant (P < 0.003). The ROC curve showed that the area under the curve is C = 0.718 with SE = 0.069 and 95% confidence interval from 0.548 to 0.852. Conclusion: In our study, we demonstrated that diffusion MRI has limited diagnostic value in the assessment of viable tumor tissue after TACE with DEBs in cases of HCC.

This article describes, for the first time, the role of the nasal mucosa (NM) as the initial site for the Histoplasma capsulatum mycelial-to-yeast transition. The results highlight that yeasts may arrive to the cervical lymph nodes (CLN) via phagocytes. Bats and mice were intranasally infected with H. capsulatum mycelial propagules and they were killed 10, 20, and 40 minutes and 1, 2, and 3 hours after infection. The NM and the CLN were monitored for fungal presence. Yeasts compatible with H. capsulatum were detected within the NM and the CLN dendritic cells (DCs) 2–3 hours postinfection, using immunohistochemistry. Histoplasma capsulatum was re-isolated by culturing at 28°C from the CLN of both mammalian hosts 2–3 hours postinfection. Reverse transcription-polymerase chain reaction assays were designed to identify fungal dimorphism, using mycelial-specific (MS8) and yeast-specific (YPS3) gene expression. This strategy supported fast fungal dimorphism in vivo, which began in the NM 1 hour postinfection (a time point when MS8 and YPS3 genes were expressed) and it was completed at 3 hours (a time point when only the YPS3 transcripts were detected) in both bats and mice. The presence of intracellular yeasts in the nasal-associated lymphoid tissue (NALT), in the NM nonassociated with the NALT, and within the interdigitating DCs of the CLN suggests early fungal dissemination via the lymph vessels.

Published: July 2019

We aimed to investigate the epidemic situation of tuberculosis (TB) in prisons in the central region of China. Tuberculosis screening was carried out in two prisons in middle China. A sum of 3,459 prisoners accepted chest X-ray examination; 40 of them were diagnosed as active TB patients. The active TB prevalence (1,156/105) was significantly higher than that of the province and China’s general population (P < 0.01). As for gender, TB prevalence in men’s prison (1,589/105) was higher than that in the women’s prison (946/105). Nevertheless, the risk of having TB in women’s prison was much higher than that in the men’s prison when compared with the TB prevalence from the province (women: OR = 2.37, 95% CI: 1.34, 4.22; men: OR = 1.53, 95% CI: 0.90, 2.60) and the China’s general population (women: OR = 3.30, 95% CI: 2.15, 5.09; men: OR = 2.06, 95% CI: 1.29, 3.30). In view of the severe epidemic situation of TB in prisons, integrating medical resources to establish a consummate and effective management system is necessary.

A previously healthy young man presented with a chronic cavitary pulmonary infection that began while in Goa, India. Burkholderia pseudomallei was cultured from sputum samples. The infection fully resolved after prolonged antibiotic treatment. Other than traveling during the monsoon season, extensive use of well-water for water-pipe smoking of cannabis was identified as a possible risk factor for infection. This is one of the first reports of travel-associated melioidosis from India. Genomic and immunological characterization suggested that the B. pseudomallei isolate collected from the reported case exhibited limited similarity to other B. pseudomallei strains.
Development of Hardware and Software for On-Board Hydrogen System

Published: July 2019

The fuel cell engine is considered to be the ultimate technical direction for the development of vehicle power. The on-board hydrogen supply system is important in fuel cell system. However, the on-board hydrogen supply system is diversified, and the management is mostly integrated in the engine controller. Thus, the fuel cell engine controller is excessive coupled with design of on-board hydrogen supply system. In order to improve the portability and compatibility of the fuel cell engine controller, an independent controller of the on-board hydrogen supply system is designed. Meanwhile, the hardware and software are developed to control 35Mpa gaseous hydrogen storage system. After being tested in a high-pressure environment, the controller can detect temperature, pressure and ambient hydrogen concentration of the hydrogen supply system. Simultaneously, it can drive and control the hydrogen cylinder valve. Besides, the controller can communicate with the Campus Area Network (CAN) bus of the fuel cell engine through the CANPro protocol analysis platform software. It is verified that the infrared signal waveform emitted by the infrared transmitting module complies with the software and hardware s of the hydrogen fuel vehicle supply station. Meanwhile, it indicates that the real-time infrared communication between the hydrogen refueling station and the controller is realized as expected. Furthermore, the controller can process and report system errors in time. Based on the results, the designed controller meets the applications requirements of the hydrogen supply system in the bus fuel cell system and improves the portability and compatibility of the hydrogen supply system.
Comparison of Autonomic Function using Valsalva Ratio, Heart Rate, and Blood Pressure in Meditators and Nonmeditators
Authors: Bassi Roopam ,   Kiran , Girgla Kawalinder
Published: July 2019

Introduction

In recent years, the various health benefits of meditation have been acknowledged by the scientific community as well as by the public. Apart from its physiological benefits, it can also improve the psychological and spiritual well-being. A case–control study was planned to investigate the effect of Rajyoga Meditation on cardiovascular autonomic activity in meditators and nonmeditators.

Materials and methods

The study was conducted on 100 subjects, randomized into two groups: meditators (n = 50; age 35.80 ± 7.69 years) and nonmeditators (n = 50; age 36.76 ± 6.38 years). The meditator group practiced meditation for 30 minutes in the morning as well as in the evening. The control group did not practice any type of meditation or relaxation techniques. The cardiovascular parameters – heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP), and Valsalva maneuver tests – were performed in both the groups in the same environmental conditions. The data were compiled and analyzed using unpaired t test.

Results

The mean values of HR in meditators and the control group were 77.08 ± 5.39 and 80.68 ± 5.71 respectively, and the difference was statistically significant (p < 0.001). The mean values of SBP in meditators and nonmeditators were 124.60 ± 5.39 and 129.56 ± 4.30 mm Hg respectively, while those for DBP were 77.84 ± 4.65 and 80.80 ± 4.78 mm Hg respectively. The difference in both was statistically significant. In meditators, Valsalva ratio was 1.60 ± 0.20, while in nonmeditators, it was 1.33 ± 0.13, and the difference was highly significant.

Conclusion

Significant improvement is seen in physiological, cardiac, and parasympathetic parameters in Rajyoga meditators. A shift of the autonomic balance toward the parasympathetic side is seen. By purposefully energizing the parasympathetic system by meditation, we can combat the ill effects of stress and help heal many health conditions.

Informed Consent: A Legal Formality or a Mandate
Authors: Kaur Navpreet
Published: July 2019

Doctor patient relationship which in olden days was a highly revered one has undergone considerable change due to the greater awareness among patients regarding their rights and easy access to litigation process. The profession which was considered the most humble one has transformed into a service and falls under the purview of Consumer Protection act. Informed consent is a concept which gives the person right to pick and choose from the different types of treatment modalities, right to voluntarily suffer any harm which may occur during treatment thereby also decreasing the burden of responsibility which falls upon the doctor's shoulders to pick the best treatment modality for his patient and to bear the brunt of patient and his relatives if something goes wrong. Thus informed consent is not just a legal formality but a mandate which guarantees not only the best treatment for the patient as per his choice but also safeguards a doctor against unnecessary litigations.

Os resultados demonstram pouco espaço dedicado à temática, ausência da sociedade civil, além de excessiva burocratização das fontes, apontando para a necessidade de leitura crítica da mídia.
Jornalismo e diversidade étnico-cultural no contexto francês: uma análise das políticas de regulação do Conselho Superior de Audiovisual
Authors: Paes Paula De Souza , Cogo Denise
Published: July 2019

Este artigo tem por objetivo analisar as limitações que dificultam a presença de minorias, especialmente as de origem migratória, nas redações de jornais franceses no contexto das políticas públicas de regulação desenvolvidas pelo CSA (Conselho Superior de Audiovisual) que visam privilegiar a diversidade étnico-cultural nos meios de comunicação. A metodologia baseia-se em uma análise empírica que se desenvolve a partir de dois eixos: o primeiro aborda a percepção que os jornalistas têm sobre o tratamento da diversidade étnico-cultural, por meio da análise das atividades da Fundação Franco-Americana voltadas para a diversidade. A Fundação é responsável por criar colóquios internacionais sobre o tratamento midiático da imigração e o Prêmio “Jornalismo da Imigração”. O segundo aborda a presença dos jornalistas de origem imigrante nas redações a partir de entrevistas semiestruturadas. As experiências desses profissionais revelam a tensão entre o imaginário social midiático e as políticas de apoio à diversidade.
A crítica de mídia na circulação dos memes de um episódio do programa jornalístico Bem Estar
Authors: De Miranda Amanda Souza
Published: July 2019

Toma-se como pressuposto a ideia de que a crítica do produto jornalístico feita pela audiência, baseada em seus repertórios sobre o que é e o que deve ser o jornalismo, indica questionamentos e tensões que devem ser observadas analiticamente. O objetivo deste estudo é apresentar um conjunto de interações com base em um episódio do programa Bem Estar que se transformou em meme nas redes sociais e compará-las a categorias da crítica acadêmica. Este exercício permite que se perceba congruências e afastamentos entre críticos que ocupam lugares diferentes, o que resulta, muitas vezes, em expectativas partilhadas sobre o que o jornalismo oferece, a partir de seus personagens, gêneros e modos de produção.
Spines and homologues in ‘araphid’ diatoms
Authors: Williams David M.
Published: July 2019

Background and aims – Many diatoms have spines on the surface of their valves. These structures differ from one taxon to another. Are all these spines the same? Are they homologues of one another? This paper sets out to explore some of the issues surrounding the determination of homologues with reference to members of Fragilariaceae.

Methods – A variety of spines from species in Fragilariaceae are examined (in the SEM) and position on the valve documented relative to those already recorded in the literature.

Key results – Spines that occur on the valves of some ‘araphid’ diatoms in Fragilariaceae can be interpreted in the light of where they are found. Spines that occur on the virgae can be thought of as modifications of that structure; spines that occur on the vimines can be thought of as modifications of that structure – the two kinds of spines are not homologues of each other. The term ‘spine’, on its own, is not useful for understanding taxon relationships; the term ‘spine’ is not even a character in the comparative biology sense but a descriptive catch-all for something that simply ‘sticks out from a surface’.

Conclusions – Systematic characters, those applicable to comparative biology, are modifications of other characters and so are, in one sense, like taxonomies: hierarchical. A consequence of this is that plotting morphological characters on molecular trees of relationships is a futile endeavour – treating characters and their modifications, as if they are static (unit) features of a non-changing entity, is book-keeping not science.

Abstract. The interannual variability of the greenhouse gases methane
(CH4) and tropospheric ozone (O3) is largely driven by natural variations in global emissions and meteorology. The El Niño–Southern
Oscillation (ENSO) is known to influence fire occurrence, wetland emission
and atmospheric circulation, affecting sources and sinks of CH4 and
tropospheric O3, but there are still important uncertainties associated
with the exact mechanism and magnitude of this effect. Here we use a
modelling approach to investigate how fires and meteorology control the
interannual variability of global carbon monoxide (CO), CH4 and O3
concentrations, particularly during large El Niño events. Using a
three-dimensional chemical transport model (TOMCAT) coupled to a
sophisticated aerosol microphysics scheme (GLOMAP) we simulate changes to
CO, hydroxyl radical (OH) and O3 for the period 1997–2014. We then use
an offline radiative transfer model to quantify the climate impact of
changes to atmospheric composition as a result of specific drivers. During the El Niño event of 1997–1998, there were increased emissions
from biomass burning globally, causing global CO concentrations to increase
by more than 40 %. This resulted in decreased global mass-weighted
tropospheric OH concentrations of up to 9 % and a consequent 4 %
increase in the CH4 atmospheric lifetime. The change in CH4
lifetime led to a 7.5 ppb yr−1 increase in the global mean CH4
growth rate in 1998. Therefore, biomass burning emission of CO could account
for 72 % of the total effect of fire emissions on CH4 growth rate in
1998. Our simulations indicate that variations in fire emissions and meteorology
associated with El Niño have opposing impacts on tropospheric O3
burden. El Niño-related changes in atmospheric transport and humidity
decrease global tropospheric O3 concentrations leading to a −0.03 W m−2 change in the O3 radiative effect (RE). However, enhanced fire emission of precursors such as nitrogen oxides (NOx) and CO
increase O3 and lead to an O3 RE of 0.03 W m−2. While globally
the two mechanisms nearly cancel out, causing only a small change in global
mean O3 RE, the regional changes are large – up to −0.33 W m−2 with potentially important consequences for atmospheric heating and
dynamics.

Published: July 2019

Abstract. Tropical giant clams of the subfamily Tridacninae, including the
species Tridacna maxima, are unique among bivalves as they live in a symbiotic relationship
with unicellular algae and generally function as net photoautotrophs. Light
is therefore crucial for these species to thrive. Here we examine the
light dependency of calcification rates of T. maxima in the central Red Sea as well as
the patterns of its abundance with depth in the field. Red Sea T. maxima show the highest
densities at a depth of 3 m with 0.82±0.21 and 0.11±0.03 individuals m−2 (mean ± SE) at sheltered and exposed sites,
respectively. Experimental assessment of net calcification (µmol CaCO3 cm−2 h−1) and gross primary production (µmol O2 cm−2 h−1) under seven light levels (1061, 959, 561, 530,
358, 244, and 197 µmol quanta m−2 s−1) showed net
calcification rates to be significantly enhanced under light intensities
corresponding to a water depth of 4 m (0.65±0.03 µmol CaCO3 cm−2 h−1; mean ± SE), while gross primary
production was 2.06±0.24 µmol O2 cm−2 h−1 (mean ± SE). We found a quadratic relationship between net calcification and
tissue dry mass (DM in gram), with clams of an intermediate size (about 15 g DM) showing the highest calcification. Our results show that the Red Sea
giant clam T. maxima stands out among bivalves as a remarkable calcifier, displaying
calcification rates comparable to other tropical photosymbiotic reef
organisms such as corals.
Proposed Best Practices for Collaboration at Cross-disciplinary Observatories

Abstract. Interdisciplinary science affords new opportunities but also presents new challenges for biogeosciences collaboration. Since 2007, we have conducted site-based interdisciplinary research in central PA, USA at the Susquehanna Shale Hills Critical Zone Observatory. Early in our collaboration, we realized the need for some best practices that could guide our project team. While we found some guidelines for determining authorship on papers, we found fewer guidelines describing how to collaboratively establish field sites, share instrumentation, share model code, and share data. Thus, we worked as a team to develop a best practices document that is presented here. While this work is based on one large team project, we think many of the themes are universal and we present our example to provide a building block for improving the function of interdisciplinary biogeoscience teams.

Abstract. An exciting research project, for example with an unusual field component, presents a unique opportunity for Education and Public Engagement (EPE). The adventure aspect of the fieldwork and the drive and creativity of the researchers can combine to produce effective, novel EPE approaches. Engagement with schools, in particular, can have a profound impact, showing the students how science works in practice, encouraging them to study science, and broadening their career perspectives. The project SEA-SEIS (Structure, Evolution and Seismicity of the Irish Offshore, www.sea-seis.ie) kicked off in 2018 with a 3-week expedition on the Research Vessel (RV) Celtic Explorer in the North Atlantic. Secondary and primary school students were invited to participate and help scientists in the research project, which got them enthusiastically engaged. In a nation-wide competition before the expedition, schools from across Ireland gave names to each of the seismometers. During the expedition, teachers were invited to sign up for live, ship-to-class video link-ups, and 18 of these were conducted. The follow-up survey showed that the engagement was not only exciting but had a lasting impact, increasing the students' interest in Science, Technology, Engineering and Mathematics (STEM) and STEM-related careers. With most of the lead presenting scientists on the ship being female, both girls and boys in the classrooms were presented with engaging role models. After the expedition, the programme continued with follow-up, geoscience-themed competitions (a song-and-rap one for secondary and a drawing one for primary schools). Many of the programme's best ideas came from teachers, who were its key co-creators. The activities were developed by a diverse team including scientists and engineers, teachers, a journalist and a sound artist. The programme's success in engaging and inspiring school students illustrates the EPE potential of active research projects. The programme's outcomes include both an increase in the students' interest in STEM and STEM careers and an increase in the researchers' interest and proficiency in EPE.
Efficient screening of groundwater head monitoring data for anthropogenic effects and measurement errors
Authors: Lehr Christian , Lischeid Gunnar
Published: July 2019

Abstract. Groundwater level data is monitored by environmental agencies to support sustainable use of groundwater resources. For this purpose a high spatial coverage of the monitoring networks and continuous monitoring in high temporal resolution is desired. This leads to large data sets that have to be quality checked and analysed to distinguish local anthropogenic influences from natural variability of the groundwater level dynamics at each well. Both technical problems with the measurements as well as local anthropogenic influences can lead to local anomalies in the hydrographs. We suggest a fast and efficient screening method for identification of well-specific peculiarities in hydrographs of groundwater head monitoring networks. The only information required is a set of time series of groundwater head all measured at the same instants of time. For each well of the monitoring network a reference hydrograph is calculated, describing expected normal behaviour at the respective well as it is typical for the monitored region. The reference hydrograph is calculated by multiple linear regression of the observed hydrograph with the stable principal components (PCs) of a principal component analysis of all groundwater head series of the network as predictor variables. The stable PCs are those PCs which were found in a random subsampling procedure to be rather insensitive to the specific selection of analysed observation wells, respectively complete series, and to the specific selection of measurement dates. Hence they can be considered to be representative for the monitored region in the respective period. The residuals of the reference hydrograph describe local deviations from the normal behaviour. Peculiarities in the residuals allow to quality check the data for measurement errors and identify wells with possible anthropogenic influence. The approach was tested with 141 groundwater head series of the state authority groundwater monitoring network in northeast Germany covering the period from 1993 to 2013 in approximately weekly resolution.

Abstract. Addressing coastal risks related to sea storms requires an integrative approach which combines monitoring stations, forecasting models, early warning systems and coastal management and planning. Such great effort is sometimes possible only through transnational cooperation, which becomes thus vital to face effectively and promptly these marine events which are responsible for several damages impacting on the environment and citizens' life. Here we present a shared and interoperable system to allow a better exchange and elaboration of information related to sea storms among countries. The proposed Integrated Web System (IWS) is a combination of a common data system for sharing ocean observations and forecasts, a multi-model ensemble system, a geoportal and interactive geo-visualization tools to make results available to the general public. Multi-model ensemble mean and spread for sea level height and wave characteristics are used to describe three different sea condition scenarios. IWS is designed to provide sea state information required for issuing coastal risk alerts over the analysed region, as well as for being easily integrated into existing local early warning systems. This study describes the application of the developed system to the exceptional storm event of 29th of October 2018, that caused severe flooding and damages to coastal infrastructures in the Adriatic Sea. The forecasted ensemble products were successfully compared with in situ observations. The hazards estimated by integrating IWS results into existing early warning systems were confirmed by documented storm impacts along the coast of Slovenia, Emilia-Romagna and the City of Venice. For the investigated event, the most severe simulated scenario resulted to provide a realistic and conservative estimation of the peak storm conditions to be used in coastal risk management.
