Eliseo Verón crea el CISECO en los primeros años de los 2000, que se constituye
en la más singular experiencia intelectual que realiza, en el sentido de llevar adelante su
concepción de semiótica abierta. Algunos fragmentos de relatos de ese proyecto muy particular, en el contexto de su largo vínculo con Brasil, son extraídos de una correspondencia mail al final de su vida. Una vez más, después de tantos años planeaba volver a Brasil. En medio a otros textos, nos deja mensajes sobre cuestiones que deben ser estudiadas en el ámbito de CISECO, como la temática de la circulación en el contexto de la investigación latinoamericana sobre la producción de sentidos.
(Re)leer a Eliseo Verón: mediación y mediatización. Dos conceptos complementarios para las Ciencias de la Información y de la Comunicación
Authors: Averbeck-Lietz Stefanie
Published: July 2019

« La mediatización es, en el contexto de la evolución de la especie, la secuencia de fenómenos mediáticos históricos que resultan de determinadas materializaciones de la semiosis, obtenidas por procedimientos técnicos » (Verón 2013a: 147). El trabajo de Verón es crucial porque combina la investigación de la mediatización con la socio-semiótica de la mediación. ¿Qué podemos aprender de Verón con respecto a nuestras sociedades digitalizadas contemporáneas? En la investigación sobre comunicación occidental y septentrional, el trabajo de Verón es, por desgracia, casi desconocido. Uno de los pocos artículos escritos en inglés de Verón se publicó en el manual de Knut Lundby sobre la mediatización en 2014. Este documento es un testimonio del concepto semio-antropológico de mediación de Verón como un proceso a largo plazo, que modifica la comunicación humana en relación con sus „dispositivos“ socio- técnicos. Esto significa: no es el contenido de un significado o el canal de medios que distribuye este contenido lo que se encuentra en el centro de una episte- mología de la comunicación social, sino las interpenetraciones mutuas entre los medios técnicos y la semiosis social. Verón adoptó este término „interpenetración“ de Niklas Luh- mann para delinear el tema del discurso de los medios bajo las condiciones de la mediati- zación acelerada. La mediación en sociedades digitalizadas está cambiando profundamente la capacidad humana de la semiosis social; sin embargo, la semiosis social como capacidad humana es la condición previa de cualquier tipo de mediatización. Este es el punto focal del pensamiento de Verón.

Authors: Wardani Desy Ayu
Published: July 2019

Background: Menopause phase in women is the time when menstrual cycle stops which is followed by obvious psychological and physical changes and occurs 3 – 4 years. The psychological and physical changes in menopause women will affect the quality of their life. Therefore, supports from the close people, especially from their husbands are needed. Objective: This study aimed to find out the correlation between husband support and the life quality of menopause women. The type of this research was quantitative research using correlation analysis with cross sectional approach with the total of 126 respondents. The technique used in taking the sample was Purposive sampling technique. Chi Square test was used as the bivariate test. Finding: The research finding showed that p-value was 0.032. Conclusion:  There was a correlation between husband support and the life quality of menopause women. Suggestion:  There should be a follow-up research about the factors which affect the life quality of menopause women such as psychological, physical aspects, social relationship and environment surrounding the menopause women.

Published: July 2019

This work presents a proof of concept for a green cyclodextrin derivatisation method that uses low-boiling epoxide reagents in a high-energy ball mill (HEBM). The simplified preparation and purification of low substitution-degree common (2-hydroxy)propylated β- and γ-cyclodextrins (β/γ-CDs) has been realised. The intelligent use of propylene oxide has also facilitated the more effective synthesis of highly substituted γ-CD. Epichlorohydrin-crosslinked CD-polymers (CDPs) have also been effectively prepared in the ball mill. The unoptimised preparations of soluble and insoluble CDPs displayed very small particle size distributions, while the prepared polymers currently have different complexation properties to those of their classically prepared analogues.

Planet atmospheric escape induced by high-energy stellar irradiation is a key phenomenon shaping the structure and evolution of planetary atmospheres. Therefore, the present-day properties of a planetary atmosphere are intimately connected with the amount of stellar flux received by a planet during its lifetime, thus with the evolutionary path of its host star. Using a recently developed analytic approximation based on hydrodynamic simulations for atmospheric escape rates, we track within a Bayesian framework the evolution of a planet as a function of stellar flux evolution history, constrained by the measured planetary radius. We find that the ideal objects for this type of study are close-in sub-Neptune-like planets, as they are highly affected by atmospheric escape, and yet retain a significant fraction of their primordial hydrogen-dominated atmospheres. Furthermore, we apply this analysis to the HD 3167 and K2-32 planetary systems. For HD 3167, we find that the most probable irradiation level at 150 Myr was between 40 and 130 times solar, corresponding to a rotation period of

days. For K2-32, we find a surprisingly low irradiation level ranging between half and four times solar at 150 Myr. Finally, we show that for multi-planet systems, our framework enables one to constrain poorly known properties of individual planets.
Double-peaked [O i] Profile: A Likely Signature of the Gaseous Ring around KH 15D
Authors: Fang Min , Pascucci Ilaria , Kim Jinyoung Serena , Edwards Suzan
Published: July 2019

KH 15D is a well-known spectroscopic binary because of its unique and dramatic photometric variability. The variability is explained by a circumbinary dust ring, but the ring itself was never directly detected. We present a new interpretation of the double-peaked [O I] λ6300 profiles as originating from the hot disk surface of KH 15D. By modeling these profiles, we measure emitting radii between ∼0.5 and 5 au, basically a gaseous ring very similar in radial extent to the dust ring inferred from modeling the system’s photometric variability. We also discuss the possibility that external photoevaporation driven by ultraviolet photons from the nearby massive star HD 47887 has truncated the outer edge of the disk to the observed value.
Multi-wavelength Variability Properties of CGRaBS J0733+0456: Identifying a Distant Gamma-Ray Blazar at z = 3.01
Authors: Liao Neng-Hui , Dou Li-Ming , Jiang Ning , Wang Yi-Bo , Fan Yi-Zhong , Wang Ting-Gui
Published: July 2019

We report on Owens Valley Radio Observatory (OVRO), WISE, Swift and Fermi-LAT observations of the high redshift blazar CGRaBS J0733+0456, from which significant flux variations in radio and infrared (IR), as well as γ-ray domains, are detected. Particularly, the amplitude of long-term IR variation is over one order of magnitude, and the IR variability timescale can be constrained as short as a few hours in the source frame. The IR and γ-ray light curves are found to be rather similar, and the strong quasi-simultaneous IR and γ-ray flares are proven to be unique among the nearby γ-ray sources. This is the first time that a γ-ray blazar at redshift z ≥ 3 with multi-wavelength flux variations (flares) is identified. Broadband spectral energy distributions in different flux states are constructed and theoretically described. The γ-ray flares from some blazars as distant as redshift ∼5 are expected to be detectable for Fermi-LAT.
How Comets Work
Authors: Fulle M. , Blum J. , Rotundi A.
Published: July 2019

Two major questions regarding comets have been up to now far from any solution. (i) How is it possible that water-ice sublimation from the nucleus surface does not lead to an insulating crust, stopping every gas and dust ejection within a few days? (ii) How is it possible that the gas flow crossing the refractory surface crust ejects dust particles bonded by tensile strengths larger than tens of Pa when the perihelion gas pressure at the nucleus-coma interface is less than one Pa? We have developed a simple but rigorous analytical model, assuming that the cometary nucleus consists of agglomerates of ice and dust (“clusters”). As soon as the clusters become exposed to sunlight, gas diffusion from their inside leads to their dehydration. We find that (i) the gas diffusing from the interior to the surface of a sunlit cluster has a steep density gradient at the cluster surface, which blasts the cluster into particles of sizes larger than or equal to those actually observed by Rosetta dust instruments; (ii) the heat-conduction and diffusion timescales are much shorter than the dehydration timescale, ensuring that the described process prevents any dumping of the nucleus activity driven by water-ice sublimation from 4 au inbound to 4 au outbound; and (iii) the clusters are in fact cm-sized pebbles, so that a cometary nucleus made of pebbles is confirmed to be the only one consistent with cometary gas and dust activity, a process unexplained until now.

Published: July 2019

BACKGROUND: The major challenge faced in Nigeria regarding the care of people living with mental illness are a stigma, caregiver burden and financial aid. This has led to high premature deaths and has also hindered the attainment of Sustainable Development Goal 3 target 4. In an attempt to find lasting solutions to increased mortality caused by mental illness, it is important to evaluate family attitudes towards people living with mental illness.AIM: To examine variations in family attitudes towards coping with people living with mental illness in Nigeria.SUBJECTS AND METHODS: Thirty In-Depth Interview (IDI) were conducted among caregivers of people living with mental illness (those presently receiving treatment and those recovering). During all the interview sessions, field notes were taken. Responses from interviewees were transcribed and analysed with the aid of ‘systematic-content analysis.RESULTS: It found out that family members of people living with mental illness or caregivers usually suffer from stress and stigma, which affects adherence to treatment.CONCLUSION: Caregivers must have sufficient knowledge and support to assume the responsibilities of caring for the mentally ill, leading to recurrence. The caregiver remains in contact with professional healthcare workers and helps the mentally ill with decision-making and matters affecting their daily life.

Authors: Tollisen Anita , Selvaag Anne Marit , Aasland Astrid , Lerdal Anners , Flatø Berit
Published: July 2019

Objective.

To describe the longitudinal health status from childhood to adulthood in patients with juvenile idiopathic arthritis (JIA), compare outcomes after 19 years with those of controls, and identify early predictors of physical functioning, pain, and physical health-related quality of life (HRQOL).

Methods.

Between 1995–2003, 96 patients with JIA (mean 6.1 ± 4.0 yrs, 67% female) were assessed within 18 months of diagnosis and every 6 months for the next 3 years with measures of JIA disease activity, physical functioning, pain, fatigue, and well-being. They were reassessed a mean of 18.9 ± 1.5 years later (mean age 25.1 ± 4.2 yrs) with measures of physical disability [Health Assessment Questionnaire–Disability Index (HAQ-DI)], pain, fatigue, well-being (visual analog scale), and physical and mental health-related quality of life (HRQOL; Medical Outcomes Study 12-item Short Form Health Survey, version 2).

Results.

During the first 3 years, physical disability improved (p < 0.001) and the proportion of patients reporting best possible well-being increased (p = 0.013), while pain and fatigue did not change. At 3- and 19-year followups, patients had similar levels of physical disability, well-being, and pain, but fatigue increased (p = 0.016) and the number of patients with HAQ-DI = 0 decreased (p = 0.001). After 19 years, patients had worse pain and physical HRQOL than controls (p < 0.001). Pain, active joints, and physical disability during the first 3 years were associated with more disability and pain and worse physical HRQOL after 19 years (p < 0.001–0.047).

Conclusion.

Patients with JIA reported similar physical functioning, well-being, and pain at 3- and 19-year followups, but more fatigue after 19 years. Patients also had worse health status than controls after 19 years. Pain, active joints, and physical disability were early predictors of unfavorable outcomes.

Published: July 2019

The longitudinal study assessed the effectiveness of hermetic storage technology in limiting aflatoxin exposure among women aged 15-45 years and children under five years of age from households in selected smallholder farming areas of Zimbabwe. Exposure levels were determined by measuring aflatoxin M1 (AFM1) in urine samples from women and children every three months during the 2015/2016 storage season for nine months. After extraction and immunoaffinity column clean up, AFM1 was determined by high performance liquid chromatography. Generally, the proportion of AFM1 positive urine samples from women increased throughout the grain storage season from 5.4% (n=23) (geometric mean (GM) 1.62 μg/l) at harvest to 75% (n=315) (GM 48.35 μg/l) nine months later (range <limit of quantification (LOQ)-217.29 μg/l). In urine samples from children, AFM1 positive samples increased from 2.2% (n=4) (GM 0.78 μg/l) at harvest to 72.5% (n=98) (GM 22.81 μg/l) nine months later (range <LOQ- 135.00 μg/l). Urinary AFM1 was significantly higher in samples from participants using conventional storage (GM 62.28 μg/l; range <LOQ-217.29 μg/l) compared with samples from participants using hermetic technology (GM 31.95 μg/l; range 0.05) hence the two technologies are equally effective in limiting exposure to aflatoxins in humans. The study concluded that aflatoxin exposure levels among women and children from small-holder farming areas increase throughout the postharvest season and the use of hermetic storage technology resulted in up to 33.2% decrease in frequency of detection and 48.7% decrease in levels of AFM1 compared to conventional storage technologies. Thus hermetic grain storage can be an effective technology recommended for limiting aflatoxin exposure in smallholder farming populations.
»Naš bengalski misijon«: Usklajevanje nacionalnih in transnacionalnih načrtov pri jugoslovanskih misijonarjih in misijonarkah v Bengaliji med obema vojnama
Authors: Motoh Helena
Published: July 2019

V nasprotju z apostolskim pismom Maximum illud, ki je od misijonarjev zahtevalo, da pretrgajo vezi z nacional(istič)nimi in kolonialnimi interesi, je bil misijonarski podvig medvojnih jugoslovanskih misijonark in misijonarjev v Bengaliji globoko prežet s patriotizmom, tako časopisje kot misijonarski tiski pa so jugoslovanski bengalski misijon prikazovali kot simbolno zmago nove jugoslovanske države. Članek želi to protislovje interpretirati z raziskavo načinov, na katere so usklajevali konflikt med transnacionalnim misijonarskim projektom in nacionalističnimi programi, pri čemer so bili pogosto pred težavno odločitvijo, interesom katere nacije naj sledijo.
Quelle alternative philosophique et éducative au consumérisme contemporain ?
Authors: Kola Etienne
Published: July 2019

Le marché est un paradigme central de l’intelligence économique contemporaine. Adopté par la plupart des États modernes, il a su opérer dans l’homme actuel une mutation spirituelle faisant de lui un fanatique de la consommation. La mécanique productiviste et consumériste ne traduit-elle pas une vision simplement matérialiste du vivre ? Ne contribue-t-elle pas à pervertir la liberté humaine ? N’est-elle pas un facteur de déséquilibre social et écologique ; un vecteur de corruption de l’éthique existentielle ? Les conceptions d’Emmanuel Levinas (1972) et de Luc Ferry (1996) de la transcendance incarnent des vertus pédagogiques dignes de révolutionner les mentalités actuelles vouées au culte du matérialisme. Organisée à partir d’une exploitation documentaire, la réflexion sera une analyse critique du consumérisme, avant d’être un plaidoyer en faveur de l’idée de transcendance telle que promue par Levinas et Ferry. Enfin, elle mettra en évidence la contribution du fait éducatif pour une reforme des mentalités.
Les accompagnateurs dans l’enseignement supérieur. Quel apprentissage suite aux affordances saisies dans un environnement multiculturel ?
Authors: Rached Patricia
Published: July 2019

La présente étude s’inscrit dans une posture socioconstructiviste et adopte l’approche qualitative, se basant sur des entretiens semi-directifs menés auprès de 18 enseignants accompagnateurs relevant de six institutions de l’Université Saint-Joseph de Beyrouth (USJ). Les résultats révèlent que les accompagnateurs, capables de percevoir et de profiter des affordances offertes par ce milieu académique multiculturel, développent des compétences et des postures à travers les divers modes d’apprentissage mis en œuvre en situation professionnelle. L’étude débouche ainsi sur la mise en évidence d’un processus de causalité circulaire engendré par le processus d’accompagnement dans un contexte qui prescrit des objectifs académiques et qui induit des objectifs conjoints, suite au multiculturalisme.
Accompagner la structuration des écrits des étudiants en travail social
Authors: Chabert Julie , Léard Franck , Souet Marc
Published: July 2019

Confronté de manière croissante aux difficultés des étudiants à livrer des écrits de formation qui soient la traduction fidèle de leur pensée, l'IFTS a mis en place une expérimentation pour accompagner les futurs travailleurs sociaux dans la structuration de leurs écrits. Cet accompagnement est focalisé sur l'écriture en tant que processus impliquant de multiples régulations et sur l'appropriation collective de l'écrit de formation. Ateliers collectifs, relecture plurielle et dialogue interrogatif avec la matière écrite invitent ainsi les étudiants à appréhender l'écriture comme un acte réflexif délibéré. Cet article se propose de rendre compte d'une démarche d'observation du processus pédagogique qui s'est déroulé sur une année pour élargir et développer cet accompagnement au sein de notre institution. Nous tentons de mettre en lumière les modalités qui permettent aux personnes en formation d'entrer dans l'écriture, d'en éprouver son cheminement et de convoquer l'autre, le lecteur, dans leurs écrits.
L’écriture réflexive dans la relation tutorale avec des professeurs-documentalistes
Authors: Pfeffer-Meyer Victoria
Published: July 2019

Cette étude est menée dans le cadre du tutorat de stagiaires professeurs documentalistes. Elle invite à réfléchir aux pratiques de formation dans la relation tutorale en utilisant l’écriture réflexive comme instrument de formation sur le lieu de stage. Nous avons élaboré trois situations d’apprentissages. Elles ont été réalisées, observées et analysées en référence au modèle de « contre transposition didactique » développé en didactique de l’information-documentation : la pratique des acteurs sert de support au travail d’écriture réflexive et détermine les objets d’apprentissage. Dans le processus réflexif, les stagiaires reviennent sur leur activité, ils mettent au jour et identifient des savoirs professionnels. La formalisation par le retour écrit sur l’action donne la possibilité d’une distanciation permettant au savoir de s’envisager dans une forme nouvelle. Ce procédé établit une trace, qui reflète une part du développement professionnel du praticien-apprenant.
Un processus d’enquête à l’université par la narration professionnelle
Authors: Mallard Simon
Published: July 2019

En s’appuyant sur le cas de professeurs des voies professionnelle et technologique entrant dans le métier, cette recherche analyse ce qui fait dispositif dans une action pédagogique visant l’analyse de situations éducatives ou d’enseignement selon une logique d’enquête collaborative. Le recours au concept de dispositif permet de comprendre le fonctionnement et les principes de cette action. Il favorise également la description et l’analyse des convergences et des tensions entre les logiques d’actions des acteurs du dispositif (concepteurs, formateurs et stagiaires en formation).Le travail par la narration est central dans ce dispositif et favorise le dialogue autour d’un métier, celui d’enseignant en lycée professionnel ou technologique. La logique d’enquête permet de soutenir la démarche d’échange entre stagiaires et de narration collective. Elle favorise la confrontation au genre professionnel du métier d’enseignant et aussi le positionnement et l’émergence d’un style d’action.
La réflexivité des professeurs des écoles stagiaires à l’aune de leur mémoire de master
Authors: Garcia Alain
Published: July 2019

Dans le champ de la formation, la notion de réflexivité fait l’objet d’une attention croissante. Nous nous intéressons ici aux mémoires de Master des professeurs des écoles stagiaires, étudiants dans une ESPE. La réflexivité de ces nouveaux enseignants semble se découvrir sous trois formes. Nous recherchons d’abord les termes associés à une réflexivité savante, dans 108 mémoires : cette forme conceptuelle est peu signalée par les auteurs. Dans un échantillon de 18 écrits, nous observons ensuite une réflexivité usuelle : elle révèle des interrogations assez convenues, que les professeurs ne paraissent guère vouloir ni pouvoir dépasser. Par logique descendante, ce sont finalement leurs élèves qui sont appelés à se questionner, à identifier leurs préjugés, à exprimer des prises de conscience, à mesurer leurs torts et à modifier leurs actions. Si elle n’exclut pas la bienveillance, cette réflexivité reportée paraît illustrer l’ordre scolaire français, dont le poids historique freinerait l’évolution
A Vision for Excellence by Design
Authors: Hickey Patricia A.
Published: July 2019

Generating evidence for care improvement has characterized my program of research spanning 20 years. Six domains are highlighted to advance the science and practice of critical care nursing in today’s complex health care systems. Employee well-being and taking care of team members are key priorities for successful leaders. Understanding that patient and staff outcomes are inextricably linked strengthens the need for care environments to be healing and holistic for staff and patients. The American Association of Critical-Care Nurses’ Healthy Work Environment framework empowers staff and optimizes the experience for patients, their families, and care teams. Appropriate staffing, guided by contemporary acuity measurement, takes into account the cognitive workload and complexity of nursing. Committing to a culture of certification and ensuring staffing models with appropriately educated and experienced nursing staff will remain important. In the past decade, we have established the impact of these specific nursing characteristics on improved patient outcomes. Understanding the attributes of empathic and empowered teams is requisite for authentic leadership. Interventions to mitigate moral distress are necessary to foster moral resilience among critical care nurses. The challenge for the future will be to support organizational health through the coexistence of highly reliable processes and clinical innovation. Excellence is achieved when systems are designed to support professional practice and clinical teams and environments.
Reverse Koebnerization in a Linear Oral Lichenoid Lesion: A Case Report
Authors: Panta Prashanth , Andhavarapu Archana , Sarode Sachin , Sarode Gargi , Patil Shankargouda
Published: July 2019

The spectacle of Koebner’s phenomenon (KP) is interesting in that trauma precipitates a subset of pathologically distinct conditions, indicating the subtle interplay between sensitization and dermato-mucosal integrity. KP is interesting because, if factors initiating it are controlled, then it may be possible to prevent these debilitating conditions through induction of reverse Koebnerization. Herein, we present a report of a patient with an erosive lesion, localized to the occlusal plane on buccal and lingual mucosa, that interestingly subsided following 1 week after a dental scaling procedure. This report analytically describes the role of dental calculus and cuspal trauma as important triggers surrounding the genesis of oral lichenoid lesion and oral lichen planus. An engaging discussion on these closely related enigmatic entities forms the central theme of this report.

Restrictions on freedom of expression in the video games industry in Russia
Authors: Abyshko Alexander , Mironova Maria , Mutygullina Alfia , Ponomarev Ivan , Sabirov German , Chuvaeva Anastasiya
Published: July 2019

The video games industry is expanding globally, and such markets as Russia have a potential for further growth attracting more and more publishers, and pushing compliance with Russian law into the business frontlines. The aim of this article is to give to the video games developers a survival kit on the Russian market highlighting the most problematic areas for foreign publishers, such as censorship, age ratings and restricted content.

The most recent trends in judicial and administrative practice show that Russian jurisdiction is extended by official bodies to foreign businesses targeting the Russian market. The LinkedIn case discussed in this article is a representative example of such an approach. More recently, the district court of Kirov decided to block access on AppStore and Google Play to video games promoting criminal subculture.

On the one hand, there are some positive trends for the game industry, like the activity of the Russian government in the field of regulating video games, namely, the Ministry of Sports of the Russian Federation has recently recognized eSports as an official sport. On the other hand, the Russian market conceals many pitfalls, for example, with regard to restricted content. The situation with respect to freedom of expression, ideas and information continues to deteriorate in all spheres of public life with video games being no exception.
Protocol: How to deal with Partial Least Squares (PLS) research in Operations Management. A guide for sending papers to academic journals
Authors: Marin-Garcia Juan A. , Alfalla-Luque Rafaela
Published: July 2019

This work protocol form part of a three-phase publication (Marin-Garcia, 2019). Its objective is to establish a work procedure to answer these questions: 1) in which journals have articles about Operations Management with Partial Least Squares (PLS) been published?; 2) Do the results of previous reviews on this topic still prevail based on the very limited set of journals that it have been conducted (and before substantial modifications were made to report methods of PLS-based studies)?; 3) Do recent articles fulfil report recommendations; 4) What kind of measurement model has been considered for the constructs most frequently used in the selected articles?; 5) What are the usual R2 values in the cross-sectional studies represented in the selected articles?; 6) Within what statistical power range do the relations analysed with PLS fall?The article summarises current recommendations to select the analysis procedures and to report the research works that have used structural equations with PLS. We believe that this is an excellent contribution for researchers because it helps to improve the analyses and reports that derive from using PLS to, thus, increase the probabilities of them being accepted in relevant journals.Another contribution made by the present work, apart from establishing the aforementioned protocol, is to provide a list of the recent articles about operations management that have used PLS and the coding procedure to conduct our systematic review (to be subsequently published).
Protocol: What does the wage structure depend on? Evidence from the INE salary national survey (pilot study with 2006 data)
Authors: Martinez-Tomas Juan , Marin-Garcia Juan A.
Published: July 2019

In previously published research, a great difference is observed concerning salary components that are used in different national contexts. In the present study, we will focus on the Spanish case by using data taken from the salary structure survey (ESS) conducted by the INE (Spanish National Statistical Organization). This protocol raises several research questions. Our main objective is to find out the incidence and degree of use of extrinsic motivation programs in the Spanish labour context. For that purpose, we propose a methodology to analyse the ESS, as well as to find out whether any research has been carried out in this regard. 2006’s pilot analysis is being presented in this moment in order to illustrate step by step the method of analysis.Our results show that both degree of use and intensity of the economic remuneration programs related to extrinsic motivation are low (e.g. in monthly payments, the most frequent component is fixed income supplements not related to shifts, which represent 75% of people from ESS2006. Then, we find variable supplements (29%) and fixed supplements related to shifts (15%). Regarding intensity, basic monthly salaries dominate by far as the major part of a salary (73%) while variable extraordinary payments (1.8%), supplements related to shifts (1%), extra hours (<1%) and payment in kind (<1 per thousand) represent a marginal amount of the total salary paid). On the other hand, our results also indicate the existence of several factors that may influence the presence of variable complements (sectoral differences, market scope, organization size, educational level or labour agreement).As additional contribution to our work, the present study allows us to know whether the sample collected by academic research is representative or not, since the incidence and extend of use of the economic participation programme should lead to similar results to those provided by the INE. On the other hand, we can identify those adjustment variables that influence in the salary distribution composition. All work done so far allows us to confirm that the research hypotheses are, at least, relevant because they have not been answered up in the literature published to date.

Abstract. Refractory black carbon (rBC) is one of the most important short-lived climate forcers in the atmosphere. Light absorption enhancement capacity largely depends on the morphology of rBC-containing particles and their mixing state. In this study, a tandem measuring system, consisting of an aerodynamic aerosol classifier (AAC), a differential mobility analyzer (DMA) and a single particle soot photometer (SP2), was adopted to investigate dynamic shape factor (𝜒) and its relationship with the mixing state of rBC-containing particles at an urban site of Beijing megacity in winter. The results demonstrated that the aerosol particles with an aerodynamic diameter of 400 ± 1.2 nm normally had a mobility diameter (Dmob) ranging from 250 nm to 320 nm, reflecting a large variation in shape under different pollution conditions. Multiple Gaussian fitting on the number mass-equivalent diameter (Dmev) distribution of the rBC core determined by SP2 had two peaks at Dmev = 106.5 nm and Dmev = 146.3 nm. During pollution episodes, rBC-containing particles tended to have a smaller rBC core than those during clean episodes due to rapid coagulation and condensation processes. The 𝜒 values of the particles were found to be ~ 1.2 during moderate pollution conditions, although the shell-core ratio (S/C) of rBC-containing particles was as high as 2.7 ± 0.3, suggesting that the particles had an irregular structure as a result of the high fraction of nascent rBC aggregates. During heavy pollution episodes, the 𝜒 value of the particles was approximately 1.0, indicating that the majority of particles tended to be spherical, and a shell-core model could be reasonable to estimate the light enhancement effect. Considering the variation in shape of the particles, the light absorption enhancement of the particles differed significantly according to the T-matrix model simulation. This study suggested that accurate description of the morphology of rBC-containing particles was crucially important for optical simulation and better evaluation of their climate effect.

Abstract. The mass loss from the Greenland Ice Sheet has increased over the
past 2 decades. Marine-terminating glaciers contribute significantly to
this mass loss due to increased melting and ice discharge. Periods of rapid
retreat of these tidewater glaciers have been linked to the concurrent
inflow of warm Atlantic-sourced waters. However, little is known about the
variability of these Atlantic-derived waters within the fjords, due to a
lack of multi-annual in situ measurements. Thus, to better understand the
potential role of ocean warming on glacier retreat, reconstructions that
characterize the variability of Atlantic water inflow to the fjords are
required. Here, we investigate foraminiferal assemblages in a sediment core
from Upernavik Fjord, West Greenland, in which the major ice stream
Upernavik Isstrøm terminates. We conclude that the foraminiferal
assemblage is predominantly controlled by changes in bottom water
composition and provide a reconstruction of Atlantic water inflow to
Upernavik Fjord, spanning the period 1925–2012. This reconstruction reveals
peak Atlantic water influx during the 1930s and again after 2000, a pattern
that is comparable to the Atlantic Multidecadal Oscillation (AMO). The
comparison of these results to historical observations of front positions of
Upernavik Isstrøm reveals that inflow of warm Atlantic-derived waters
likely contributed to high retreat rates in the 1930s and after 2000.
However, moderate retreat rates of Upernavik Isstrøm also prevailed in
the 1960s and 1970s, showing that glacier retreat continued despite a reduced
Atlantic water inflow, albeit at a lower rate. Considering the link between
bottom water variability and the AMO in Upernavik Fjord, and the fact that a
persistent negative phase of the AMO is expected for the next decade,
Atlantic water inflow into the fjord may decrease in the coming decade,
potentially minimizing or stabilizing the retreat of Upernavik Isstrøm
during this time interval.
Alluvial channel response to environmental perturbations: fill-terrace formation and sediment-signal disruption

Published: July 2019

Abstract. The sensitivity of fluvial systems to tectonic and
climatic boundary conditions allows us to use the geomorphic and
stratigraphic records as quantitative archives of past climatic and tectonic
conditions. Thus, fluvial terraces that form on alluvial fans and
floodplains as well as the rate of sediment export to oceanic and
continental basins are commonly used to reconstruct paleoenvironments.
However, we currently lack a systematic and quantitative understanding of
the transient evolution of fluvial systems and their associated sediment
storage and release in response to changes in base level, water input, and
sediment input. Such knowledge is necessary to quantify past environmental
change from terrace records or sedimentary deposits and to disentangle the
multiple possible causes for terrace formation and sediment deposition.
Here, we use a set of seven physical experiments to explore terrace
formation and sediment export from a single, braided channel that is
perturbed by changes in upstream water discharge or sediment supply, or
through downstream base-level fall. Each perturbation differently affects
(1) the geometry of terraces and channels, (2) the timing of terrace
cutting, and (3) the transient response of sediment export from the basin.
In general, an increase in water discharge leads to near-instantaneous
channel incision across the entire fluvial system and consequent local
terrace cutting, thus preserving the initial channel slope on terrace
surfaces, and it also produces a transient increase in sediment export from
the system. In contrast, a decreased upstream sediment-supply rate may
result in longer lag times before terrace cutting, leading to terrace slopes
that differ from the initial channel slope, and also lagged responses in
sediment export. Finally, downstream base-level fall triggers the upstream
propagation of a diffuse knickzone, forming terraces with
upstream-decreasing ages. The slope of terraces triggered by base-level fall
mimics that of the newly adjusted active channel, whereas slopes of terraces
triggered by a decrease in upstream sediment discharge or an increase in
upstream water discharge are steeper compared to the new equilibrium
channel. By combining fill-terrace records with constraints on sediment
export, we can distinguish among environmental perturbations that would
otherwise remain unresolved when using just one of these records.
Implementation of an immersed boundary method in the Meso-NH v5.2 model: applications to an idealized urban environment

Abstract. This study describes the numerical implementation, verification and validation of an immersed boundary method (IBM) in the atmospheric solver Meso-NH for applications to urban flow modeling. The IBM represents the fluid–solid interface by means of a level-set function and models the obstacles as part of the resolved scales. The IBM is implemented by means of a three-step procedure: first, an explicit-in-time forcing is developed based on a novel ghost-cell technique that uses multiple image points instead of the classical single mirror point. The second step consists of an implicit step projection whereby the right-hand side of the Poisson equation is modified by means of a cut-cell technique to satisfy the incompressibility constraint. The condition of non-permeability is achieved at the embedded fluid–solid interface by an iterative procedure applied on the modified Poisson equation. In the final step, the turbulent fluxes and the wall model used for large-eddy simulations (LESs) are corrected, and a wall model is proposed to ensure consistency of the subgrid scales with the IBM treatment. In the second of part of the paper, the IBM is verified and validated for several analytical and benchmark test cases of flows around single bluff bodies with an increasing level of complexity. The analysis showed that the Meso-NH model (MNH) with IBM reproduces the expected physical features of the flow, which are also found in the atmosphere at much larger scales. Finally, the IBM is validated in the LES mode against the Mock Urban Setting Test (MUST) field experiment, which is characterized by strong roughness caused by the presence of a set of obstacles placed in the atmospheric boundary layer in nearly neutral stability conditions. The Meso-NH IBM–LES reproduces with reasonable accuracy both the mean flow and turbulent fluctuations observed in this idealized urban environment.
A new bias-correction method for precipitation over complex terrain suitable for different climate states
Authors: Velasquez Patricio , Messmer Martina , Raible Christoph C.
Published: July 2019

Abstract. This work presents a new bias-correction method for precipitation that considers orographic characteristics, which makes it flexible to be used under highly different climate conditions, e.g., glacial conditions. The new bias-correction and its performance are presented for Switzerland using a regional climate simulation under perpetual 1990 conditions at 2-km resolution driven by a simulation performed with a global climate model. Comparing the regional simulations with observations, we find a strong seasonal and height dependence of the bias in precipitation commonly observed in regional climate modelling over complex terrain. Thus, we suggest a 3-step correction method consisting of (i) a separation into different orographic characteristics, (ii) correction of low intensity precipitation, and finally (iii) the application of empirical quantile mapping, which is applied to each month separately. Testing different orographic characteristics shows that separating in 400-m height-intervals provides the overall most reasonable correction of the biases in precipitation and additionally at the lowest computational costs. The seasonal precipitation bias induced by the global climate model is fully corrected, whereas some regional biases remain, in particular positive biases in winter over mountains and negative biases in winter and summer in deep valleys and Ticino. The biases over mountains are difficult to judge, as observations over complex terrain are afflicted with uncertainties, which may be more than 30 % above 1500 m a.s.l. A rigorous cross validation, which trains the correction method with independent observations from Germany, Austria and France, exhibits a similar performance compared to just using Switzerland as training and verification region. This illustrates the robustness of the new method. Thus, the new bias-correction provides a flexible tool which is suitable in studies where orography strongly changes, e.g., during glacial times.
