Published: March 2020

The Dynamic Albedo of Neutrons (DAN) instrument designed to detect neutrons in order to determine hydrogen abundance in the Martian subsurface (down to 1 m deep) is successfully working onboard Mars Science Laboratory (MSL) Curiosity rover for more than seven years. The Curiosity rover covered more than 20 km on the Martian surface and crossed a range of terrain types and geological structures of different mineralogical composition.

We investigate the possible correlation between the water equivalent hydrogen (WEH) value, as measured by DAN along the Curiosity traverse, and the presence of hydrated minerals, as observed from the orbit by Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) onboard Mars Reconnaissance Orbiter.  

Our analysis of the WEH value from DAN measurements in Gale crater and the CRISM data, reflecting the distribution of hydrated/hydroxylated minerals on the surface of this crater, shows a confident increase of the average WEH values for the surface elements, containing certain types of minerals, in comparison with surface elements, that do not contain any of them. This increase is shown to become higher for surface with more prominent spectral features of hydrated/ hydroxylated minerals on the surface. Thus, certain types of minerals being parts of the sedimentary deposits composing Gale crater, should have considerable thickness, which is sufficient for active neutron sensing in DAN measurements. To explain the correspondence, one may assume that large blocks of certain mineral composition are distributed over the traverse, the tops of which are observed by CRISM from the Martian orbit, and the volumes of which are detectable by DAN on the Martian surface.

The bottom of the crater is thought to be a composition of a uniform regolith and sedimentary blocks of minerals with different level of hydration. The fraction of the regolith contains a standard value of WEH, about 2.6 wt.%, and the  fraction of minerals, provided they are there, might contribute to some increase of the mean WEH values, up to 3.8 wt.%, as they are obtained at some spots from the DAN neutron sensing.
Predictive modeling of hourly probabilities for weather-related road
accidents
Authors: Becker Nico , Rust Henning W. , Ulbrich Uwe
Published: March 2020

Abstract. An impact of weather on road accidents has been identified in several studies with a focus mainly on monthly or daily accident counts. We study hourly probabilities of road accidents caused by adverse weather conditions in Germany on the spatial scale of administrative districts. Meteorological predictor variables from radar-based precipitation estimates, high-resolution reanalysis and weather forecasts are used in logistic regression models. Models taking into account temperature and hourly precipitation sums reach the best predictive skill according to different metrics. By introducing meteorological variables, the models hit rate is increased from 0.3 to 0.7, while keeping the false alarm rate constant at 0.2. Accident probability has a non-linear relationship with precipitation. Given an hourly precipitation sum of 1 mm, accident probabilities are about 5 times larger at negative temperatures compared to positive temperatures. Based on ensemble weather forecasts skilful predictions of accident probabilities of up to 21 hours are possible; the loss of skill compared to a model using radar and reanalysis data is negligible. The findings are relevant in the context of impact based warnings for both road users, road maintenance and traffic management authorities, as well as rescue forces.

Si el paganismo primitivo presentaba mitos sabré dioses metamorfoseados en seres tamales y leyendas acerca de personas elevadas a deidades, aquel día en el monte solo un hombre pudo mostrar la verdad de que Él ni es un dios cualquiera materializado, ni un humano con pretensión de divinidad. Porque es el mismo y único Dios desde antes de la fundación del universo; porque es, no una luz, sino La verdadera, sin principio ni fin en la eternidad; desde siempre existente, antes de la orden del Creador "iFiat lux! Sobre el caos (Génesis 1:3 y Juan 1:1). La semana previa a su ascensión al Tabor había confirmado la confesión padrina en punto al misterio del ungido unigénito del Todopoderoso, profetizado mil veces por mil voces; había anticipado por primera vez su destino pasional, que culminaría en el Calvario. Fue anuncio de la lucha entre un monte de brillo y otro de tinieblas, desde el cual se ofrecería manso en oblación sublime, para rutilar triunfante contra la oscuridad.

Contaminación natural por arsénico en las aguas subterráneas de la comunidad rural “La Fuente”, para sugerir y promover el uso de fuentes alternativas de agua segura municipio La Paz Centro, León, Nicaragua
Authors: Altamirano Maximina , Delgado Valeria
Published: March 2020

Estudios previos han revelado que en Nicaragua la presencia de arsénico es de origen geogénico por lo que es común encontrarlo en aguas tanto superficiales como subterráneas, suelo, rocas y sedimentos; además de encontrarse en los complejos volcánicos, fumarolas, fuentes termales, gases y fluidos geotérmicos. Fue hasta el 2010 cuando el arsénico fue detectado en materiales volcánicos y sedimentarios del Cuaternario presentes en el arco volcánico de la Cordillera de Los Maribios. Es así, que en la Comunidad de La Fuente localizada al NE del complejo volcánico Momotombo-El Hoyo y cerca de la Caldera Monte Galán, donde 112 familias se abastecen de agua subterránea, se determinó la concentración de arsénico total en agua de 30 pozos excavados, tres pozos perforados y un manantial. Las concentraciones de arsénico oscilaron en el rango desde 2 µg·l-1 (Casas de Rafaela Rojas y Porfirio Reyes) hasta 103 µg·l-1 en el manantial Aguas Calientes (La Chistatosa). El 70% de las muestras analizadas (24 fuentes) exceden el límite nacional adoptado por el país de 10 µg As∙l-1 para agua de consumo humano. Los sitios con las mayores temperaturas (35,6 a 45,8 °C) son los que presentan las mayores concentraciones de arsénico (38 a 103 µg l-1), mayores valores de conductividad eléctrica (983 – 1140 µS∙cm-1) y menores valores de pH (5,80 – 7,08 unidades). Los pobladores fueron informados sobre el riesgo al que están expuestos por ingerir agua contaminada con altos valores de este tóxico; a la vez que se identificaron fuentes seguras de agua para consumo humano, las cuales fueron recomendadas a los usuarios. Esta investigación, además de generar información científica, se convierte en una herramienta para apoyar en la toma de decisiones por parte de las autoridades, y cambio por parte de los pobladores locales en el uso de fuentes alternativas para agua de consumo humano y de preparación de sus alimentos.

Authors: López Hernández Maybis , Lacayo Romero Martha
Published: March 2020

El objetivo de esta investigación fue remover el cromo hexavalente de aguas contaminadas utilizando cáscara de plátano como adsorbente. El estudio se realizó en dos etapas: en la primera etapa, se trabajó con 1 g de la biomasa a un tamaño de partícula de aproximadamente 600 µm,15 minutos de contacto, 20 mg.l-1 de cromo hexavalente y a pH 3, 3,5, 5 y 7. En la segunda etapa, se trabajó con las mismas condiciones de masa y tiempo a pH 3 y 3,5 aumentando la concentración del metal de 20 a 40 y 80 mg.l-1. Los resultados obtenidos muestran que al aumentar el pH disminuye el porcentaje de remoción y la capacidad de adsorción, no obstante, a pH 3 y 3,5 la biomasa remueve más del 92% de cromo hexavalente y al aumentar la concentración aumenta la capacidad de adsorción de la cáscara de plátano. Los datos experimentales se ajustan más al modelo de Langmuir que al de Freundlich lo que muestra una adsorción en monocapa de una superficie homogénea. Además, el factor de separación RL se mantuvo entre 0,809 a 0,383 lo que indica una adsorción favorable del metal pesado en la biomasa. La cáscara de plátano tiene gran potencial como adsorbente para la remoción de cromo hexavalente en aguas.

INTERNATIONAL LABOUR STANDARDS IN THE GLOBAL ECONOMY: PAST, PRESENT AND FUTURE
Authors: Sengenberger Werner
Published: March 2020

The foundation of the International Labour Organization is the off spring of a reform project to improve labour conditions in the face of revolutionary movements during and after World War I. In its 100-year history, the ILO has created a comprehensive system of minimum international labour standards largely laid down in Conventions and Recommendations, together with a supervisory mechanism and technical assistance for the application and control of the norms. The ILO norms are universally valid, independently of a country’s level of development, culture, tradition, and category of worker or enterprise. Conventions classifi ed as fundamental are rated as human rights. They have to be respected and promoted by ILO member countries independently of ratification. ILO labour standards are directed to set an eff ective fl oor to wages, hours of work, conditions of employment and social services for all countries engaged in international competition in order to prevent social dumping and achieve fair and stable globalization. The relevance of the standards has grown with the successive stages of global economic interdependence and integration, driven by multi-national companies, cross-national supply chains and trade agreements. Abundant empirical evidence shows that the observance of ILO rules generates economic, social and political dividends
A GLIMPSE INTO THE PRESENT AND FUTURE OF LABOUR LAW AND INDUSTRIAL RELATIONS IN CENTRAL AND EASTERN EUROPE
Authors: Mihes Cristina
Published: March 2020

This paper seeks to take a look at recent labour law reforms in a number of selected CEE countries, and to examine the manner, in which the equation of standard employment relationship and the dynamics of collective bargaining processes have changed. The 1st section discusses the policy goals as well as drivers of legal changes, which have aff ected and guided recent labour law reforms in the sub-region. External infl uences over shaping of the new policy visions and recovery policies are also examined here. The 2nd section examines recent trends in regulating standard and non-standard employment relationship, as well as the collective agreements as determinants of working conditions and terms of employment. It also analyses the new approaches in the implementation of the guiding principles of collective bargaining, including the autonomy of the parties, and the principle of favourability. Furthermore, the 3rd section seeks to explore what the future looks like by traveling the paths opened by the works of the ILO Global Commission on the Future of Work, with a special focus on the Universal Labour Guarantee. Finally, a number of conclusions are drawn on the basis of the analysed data and policies.
Experimental Trajectories of Young Users of Psycho-active Prescription Drugs in Urban Indonesia
Authors: Idrus Nurul Ilmi , Hardon Anita
Published: March 2020

In Indonesia, a country with stringent drug laws, psycho-active prescription drugs (PPDs) have become popular among urban youth as they are seen to be safe – both medically and in terms of the risks of being arrested. During the ChemicalYouth project, which involved a multi-sited ethnography in urban centers in South Sulawesi (Makassar, Gowa, and Maros) and in Yogyakarta, we found that young people encourage each other to try out different kinds of PPDs to determine which (combinations) work best for them. Sharing their experiences, they jointly build up knowledge that guides their ‘experimental trajectories’ (Raikhel and Garriott 2013). The experimental trajectories of youths are enabled by pharmacies, where young people can buy PPDs, and private sector doctors who sell and prescribe PPD prescriptions. When certain PPDs become harder to get, young people will try out new substances in their search for happiness, highs, and the confidence and stamina needed to perform precarious informal sector jobs such as sex work, street singing, and helping people park their cars. Across the sites, the researchers encountered young people realizing that they had become addicted to PPDs. Simultaneously, health workers lack instruments to prevent harm related to PPD use as they work in public sector harm reduction programs designed narrowly to address illicit heroin addiction. We argue that educational interventions need to address the desires and aspirations for good enough lives that are reflected in young people’s creative poly-drug use practices, and the iatrogenic effects of unregulated pharmaceutical markets that enable medicalization of precarious lives.
On the Sensory Policing of Vices
Authors: Leser Julia
Published: March 2020

This paper explores the policing of vices and offers a critical inquiry into the affective politics of policing practices seen through police and state ethnography, political anthropology, and the ‘affective turn’ in social and cultural theory. It shows how the moral worlds of policing sex work and performing raids in the red-light ‘milieu’ are constituted in the making of boundaries through visual, olfactory, somatosensory, and auditory sensations, which can be understood as normative performances in the realm of morality. Police officers do not engage in a neutral gaze but transform the sensuous into sensations that enact these normative distinctions between the ‘normal’ and the ‘abnormal’ – the morally questionable red-light ‘milieu.’ These practices can be read in regard to a morality that is conveyed in and through the officers’ sensational performances in an observingly affective and somatic manner. Morality not simply is but is being done—and performing affects and sensations plays a significant role in the making of moral worlds in the realm of policing. Raiding the red-light ‘milieu’ is a performance on disorder and order, on what is normal and what is not, and thus a deeply political practice that reveals how order- and boundary-making operates through basic sensations and feelings, of the sensuous, the aesthetic, and the somatic.
Micromobilization through live streaming: the Elin Ersson case
Authors: Khattab Mona
Published: March 2020

Live streaming is a media innovation that enables individuals to communicate with thousands of social media users instantly. This article explores how live streaming is used to support micromobilization in the context of social activism. It focuses on the case of live streaming from an airplane by the Swedish activist Elin Ersson. This live stream aimed to prevent the deportation of an Afghani asylum-seeker from Sweden. A qualitative content analysis of both the live streamed video and the viewers’ responses is undertaken. Two typologies for Social Behavior in live streamed micromobilization are developed, namely Digital Support Behavior (DSB) and Digital Rejection Behavior (DRB). Analyzing the content of the live stream and the viewers responses according to these typologies reveals that live streaming can support individualized micromobilization.
Fast-Spectrum Fluoride Molten Salt Reactor (FFMSR) with Ultimately Reduced Radiotoxicity of Nuclear Wastes
Authors: Hirose Yasuo
Published: March 2020

A mixture of NaF-KF-UF4 eutectic and NaF-KF-TRUF3 eutectic containing heavy elements as much as 2.8 g/cc makes a fast-spectrum molten salt reactor based upon the U-Pu cycle available without a blanket. It does not object breeding but a stable operation without fissile makeup under practical contingencies. It is highly integrated with online dry chemical processes based on “selective oxide precipitation” to create a U-Pu cycle to provide as low as 0.01% leakage of TRU and nominated as the FFMSR. This certifies that the radiotoxicity of HLW for 1500 effective full power days (EFPD) operation can be equivalent to 405 tons of depleted uranium after 500 years cooling without Partition and Transmutation (P&T). A certain amount of U-TRU mixture recovered from LWR spent fuel is loaded after the initial criticality until U-Pu equilibrium but the fixed amount of 238U only thereafter. The TRU inventory in an FFMSR stays at an equilibrium perpetually. Accumulation of spent fuel of an LWR for 55 years should afford to start up the identical thermal capacity of FFMSR and to keep operation hypothetically until running out of 238U. Full deployment of the FFMSR should make the entire fuel cycle infrastructures needless except the HLW disposal site.
Genotype and Phenotype Concordance for Pharmacogenetic Tests Through Proficiency Survey Testing
Authors: Moyer Ann M. , McMillin Gwendolyn A. , Long Thomas A. , Gandhi Manish J. , Mao Rong , Smock Kristi J. , Halley Jaimie G. , Weck Karen E.
Published: March 2020

Context.—

As pharmacogenetic testing is incorporated into routine care, it is essential for laboratories to provide accurate and consistent results. Certified laboratories must successfully complete proficiency testing.

Objectives.—

To understand and examine trends in participation and performance of laboratories participating in the College of American Pathologists pharmacogenetic proficiency testing surveys.

Design.—

Results from College of American Pathologists pharmacogenetic proficiency testing challenges from 2012 through 2017 were reviewed for concordance with expected genotype and phenotype for each sample (intended responses).

Results.—

Laboratories correctly reported results for 96.7% to 100% of samples with no variants. Excluding CYP2D6, laboratories correctly detected and reported variant alleles for each gene (93.7%–99.2% correct). CYP2D6 showed lower concordance, with 83.1% of laboratories reporting the intended genotype across all samples; however, in many cases, the laboratories that did not report a variant allele did not test for that allele. Among laboratories reporting the intended genotype, most successfully reported the intended phenotype (85.9%–99.0%).

Conclusions.—

Although laboratories are generally performing well, there is room for additional improvement, particularly for challenging genes, such as CYP2D6. Efforts in the field of pharmacogenomics to recommend alleles that should be included in clinical tests, identify reference materials, and standardize translation from genotype to phenotype may address some of the remaining variability in results.
Sängerische höchstleistung und mentale strategien – eine interviewstudie mit langjährig erfolgreichen klassischen sängerinnen
Authors: Schwarz Silke , Melzer Caroline
Published: March 2020

Langjährig erfolgreiche SängerInnen müssen in der Lage sein, ihr Potential über einen Karriereverlauf durchgehend auf hohem Niveau abzurufen und sowohl die eigenen als auch fremden Erwartungen an die künstlerische Leistung miteinander in Einklang bringen. Die Einschätzung von sängerischer Bestleistung divergiert dabei in hohem Maße. Eine langjährige, professionelle Gesangskarriere setzt deswegen neben körperlicher Belastbarkeit und künstlerischer Exzellenz auch mentale Stärke voraus, um mit den teils widersprüchlichen Erwartungshaltungen von Publikum, AgentInnen, musikalischen PartnerInnen, Casting DirektorInnen oder Coaches umzugehen und die eigene Leistungsfähigkeit langfristig auf hohem Niveau zu erhalten. Professionelle SportlerInnen nutzen mentale Trainingstechniken als Ergänzung zum physischen Training seit Jahrzehnten, da die Vorteile eines kombinierten mentalen und praktischen Trainings wissenschaftlich belegt sind. Die vorliegende Arbeit fokussiert die Gütemaßstäbe, mit denen langjährig erfolgreiche SängerInnen ihre Bestleistung definieren und führt auf, welche Strategien sie zur Erreichung derselben nennen. Die Ergebnisse der Interviewstudie zeigen, dass soziale, körperliche, situative und mentale Determinanten das Erreichen der Bestleistung beeinflussen. Entsprechend der positiven oder negativen Selbstbewertung dieser Determinanten wird das Erreichen der persönlichen Bestleistung begünstigt oder gestört. Die Studie zeigt, dass die SängerInnen ihre Bestleistung auf unterschiedliche Weise definieren, entweder mit Idealbezug, Realbezug oder Defizitbezug. Je nach Bezug nennen SängerInnen unterschiedliche mentale Strategien, um ihre Befindlichkeit und ihren Tonus zu regulieren. Dadurch aktivieren und erhalten sie ihre Fokussierungsfähigkeit, ihre Selbstkompetenzüberzeugung und ihre Handlungsfähigkeit.

O Kyrie de Nepomuceno: estilo e intertextualidade
Authors:   Universidade Federal do Paraná, Teixeira Thiago Plaça
Published: March 2020

O presente artigo apresenta uma análise do Kyrie da Missa em Ré menor (1915) de Alberto Nepomuceno (1864-1920), visando identificar características estilísticas e relações de intertextualidade musical. Quanto à forma, textura e timbre, o Kyrie de Nepomuceno apresenta grande semelhança com o Kyrie da Missa Te Deum laudamus (1899), de Lorenzo Perosi (1872-1956). Quanto à harmonia, a obra denota certo caráter modal, possivelmente por influência de técnicas de harmonização do canto gregoriano. Quanto à melodia e à prosódia, nota-se certa proximidade com as linhas melódicas gregorianas, consideradas então paradigma da música sacra católica.

Uma grande parte das escolas públicas brasileiras não realizam nenhum tipo de tratamento de lixo. São poucas as escolas que buscam soluções para as questões ambientais da atualidade.  Esse trabalho objetiva, portanto, caracterizar os resíduos sólidos de uma instituição de ensino da rede pública estadual do município de Barreiras/BA, para firmar futuras propostas de sustentabilidade.  Essa pesquisa quali-quantitativa é será desenvolvida por um estudo de caso um. As caracterizações dos resíduos sólidos escolares compreenderam na coleta, acondicionamento, pesagem e separação. Foi verificado que a escola produz em média diária 53,05kg de resíduos sólidos, e no detalhamento da composição física destes resíduos, os orgânicos representam 56%; outros 10%; papel 26%; plástico 4%; e alumínio 4,0%. No geral, estes valores são consideráveis e requer atenção devido aos impactos ambientais que podem ser provocados. Esses dados confirmam que há uma universalização da sociedade de consumo e urgente necessidade de uma educação ambiental.
¿Qué profesional de la educación para qué escuela y para qué sociedad?
Authors: García Gómez Teresa
Published: March 2020

Este artículo, resultado de la revisión y reflexión teórica, responde a la pregunta que todo profesional de la educación debería formularse: qué ser humano se desea formar para qué sociedad. Si aspiramos a una sociedad más justa y más humana, una sociedad convivencial, constituida por sujetos libres y emancipados, que es el planteamiento de este trabajo, necesitamos formar docentes, desde la pedagogía crítica, como agentes de cambio e intelectuales transformadores para que contribuyan al desarrollo de escuelas democráticas. Es decir, docentes que configuren un currículum contrahegemónico en el marco de una organización participativa en colaboración con la comunidad, instancias y movimientos sociopolíticos.

This article, resulting from theoretical review and reflection, answers the question that every education professional should ask themselves: what human being is to be trained for what society. If our ambition is for a fairer and more humane society, a convivial society made up of free and emancipated subjects, which is the approach of this work, there is a need to train teachers, from critical pedagogy, as agents of change or transformative intellectuals so that they help towards the development of democratic schools. That is to say, teachers who shape a counterhegemonic curriculum in the context of a participatory organisation in collaboration with the community, authorities and sociopolitical movements.

The teaching community in Early Childhood Education represents a key element to promote an inclusive education and to identify what competences must be acquired in their initial training. The objective of this paper is to show the design and validation process of a questionnaire aimed at learning the competences which must be present in the degree in Early Childhood Education at the University of El Bosque (Bogotá, Colombia). There has been a sample of 158 participants: 7 judges, 92 students, 35 graduates and 24 employers. The instrument elaborated is made up of 53 items distributed in four dimensions – scientific, social, methodological and personal competences. The procedure has complied with the following phases: 1) revision of the state of art and initial elaboration of the questionnaire; 2) content validity through the expert judgement technique and introduction of the necessary changes; 3) instrument implementation; 4) analysis of the statistical reliability. The results show that the CEINCLUSIVA questionnaire is a valid and reliable instrument with a Cronbach’s alpha of .964. for all items. These positive results recur in every dimension of the instrument elaborated. Likewise, the judges’ agreement relating to the pertinence, relevance, clarity and exclusivity of the proposed items stands out.
La enseñanza de la interculturalidad a través de la literatura: nuevos desafíos
Authors: Kunešová Květuše
Published: March 2020

La enseñanza de la literatura en las escuelas secundarias de la República Checa, contribuye de manera relevante a ofrecer nuevas perspectivas educativas a los jóvenes checos. En tal sentido, esta enseñanza funciona como atesoran en el mundo, desde la Odisea de Homero, por ejemplo, a través del drama Shakesperiano y Fausto de Goethe, a las novelas de Balzac o de Zola, a los autores del siglo XX que se dedicaron a la causa humanista desvelando las facetas ocultas de la existencia humana. El propósito de nuestra reflexión sobre temas interculturales es, en primer lugar, analizar la contribución de la lectura al nivel de conocimiento, proponer la posibilidad de utilizar textos literarios para demostrar hasta qué punto el diálogo entre culturas, está incluido en las propias obras, y, por último, considerar qué textos literarios contemporáneos a escala mundial podrían enriquecer de manera relevante la selección de libros recomendados a los jóvenes checos. La conclusión será una síntesis tratando de comparar la situación de los estudiantes checos con la de los jóvenes franceses. También se resalta el papel de la traducción no sólo en la enseñanza de la literatura, sino en el conocimiento del Otro.

The teaching of literature in secondary schools in the Czech Republic (note that this is in the course of Czech literature courses and taught in Czech) contributes in a relevant way to open to young people new worlds. It works starting from the treasury of the world thought, Homer’s Odyssey for example through Shakespearean drama and Goethe’s Faust, to the novels by Balzac or by Zola, to the twentieth century authors who engaged in the humanist cause by unveiling the hidden facets of human existence. The purpose of our reflection on intercultural topics is first of all to analyze the contribution of reading to the level of knowledge, then to propose the possibilities of using literary texts to demonstrate how much the dialogue between cultures is included in the works themselves, and finally, to consider which contemporary literary texts on a world scale could enrich in a relevant way the choice of books recommended to young Czechs. The conclusion will be a synthesis trying to compare the situation of Czech students to that of young Frenchmen, for example. It will also highlight the role of translation not only in teaching literature, but in knowing the Other.

Authors: Tessier Laurent , Tremion Virginie
Published: March 2020

En la post-Web 2.0, el papel del vídeo se ha vuelto cada vez más importante, tanto en el e-learning como en los sistemas de aprendizaje semipresencial. Este artículo pretende identificar cómo la anotación en vídeo puede ayudar a explorar la comunicación en la formación de profesores. Habida cuenta de la necesidad de tener en cuenta la gran diversidad de alumnos, el trabajo en colaboración y los intercambios en línea pueden contribuir a aumentar la comprensión de la comunicación intercultural. En primer lugar, comenzamos con una presentación de anotaciones en vídeo colaborativo para observar el lugar y el papel de la interacción en este sistema. A continuación, tratamos de descubrir elementos del proceso de diseño en un proyecto de investigación basado en el diseño sobre el celuloide, un dispositivo de anotación de vídeo a través de la descripción de dos experimentos: sus contextos, los vídeos utilizados, las modalidades de consulta y los procesos de anotación desarrollados para aumentar la interacción.

In post-Web 2.0, the role of video has become increasingly important, both in e-learning and in blended learning systems. This article aims to identify how video annotation can help explore communication in teacher training. With the necessity to take into account the great diversity of pupils, collaborative work and online exchanges may help increase understanding of intercultural communication. Firstly, we begin with a presentation of collaborative video annotation to observe the place and the role of interaction in this system. Then, we seek to uncover elements of the design process in a design-based research project on Celluloid, a video annotation device through the description of two experiments: their contexts, the videos used, the consultation modalities and the annotation processes developed to increase interaction.
Evaluating Cardiovascular Disease (CVD) risk scores for participants with known CVD and non-CVD in a multiracial/ethnic Caribbean sample
Authors: Hosein Amalia , Stoute Valerie , Chadee Samantha , Singh Natasha Ramroop
Published: March 2020

Background

Cardiovascular Disease (CVD) risk prediction models have been useful in estimating if individuals are at low, intermediate, or high risk, of experiencing a CVD event within some established time frame, usually 10 years. Central to this is the concern in Trinidad and Tobago of using pre-existing CVD risk prediction methods, based on populations in the developed world (e.g. ASSIGN, Framingham and QRISK®2), to establish risk for its multiracial/ethnic Caribbean population. The aim of this study was to determine which pre-existing CVD risk method is best suited for predicting CVD risk for individuals in this population.

Method

A survey was completed by 778 participants, 526 persons with no prior CVD, and 252 who previously reported a CVD event. Lifestyle and biometric data was collected from non-CVD participants, while for CVD participants, medical records were used to collect data at the first instance of CVD. The performances of three CVD risk prediction models (ASSIGN, Framingham and QRISK®2) were evaluated using their calculated risk scores.

Results

All three models (ASSIGN, Framingham and QRISK®2) identified less than 62% of cases (CVD participants) with a high proportion of false-positive predictions to true predictions as can be seen by positive predictabilities ranging from 78% (ASSIGN and Framingham) to 87% (QRISK®2). Further, for all three models, individuals whose scores fell into the misclassification range were 2X more likely to be individuals who had experienced a prior CVD event as opposed to healthy individuals.

Conclusion

The ASSIGN, Framingham and QRISK®2 models should be utilised with caution on a Trinidad and Tobago population of intermediate and high risk for CVD since these models were found to have underestimated the risk for individuals with CVD up to 2.5 times more often than they overestimated the risk for healthy persons.
Effects of diversity and coalescence of species assemblages on ecosystem function at the margins of an environmental shift
Authors: Werba Jo A. , Stucy Alexandra L. , Peralta Ariane L. , McCoy Michael W.

Sea level rise is mixing formerly isolated freshwater communities with saltwater communities. The structure of these new aquatic communities is jointly controlled by pre- and post-colonization processes. Similarly, since salinity is a strong abiotic determinant of post-colonization survival in coastal systems, changes in salinity will likely impact community composition. In this study, we examine how a strong abiotic gradient affects the diversity and structure of bacterial and zooplankton communities and associated ecosystem functions (decomposition and carbon mineralization). We ran a six week dispersal experiment using mesocosm ponds with four distinct salinity profiles (0, 5, 9, and 13 psu). We find that salinity is the primary driver of both bacterial and zooplankton community composition. We find evidence that as bacterial richness increases so does the amount of decomposition. A phenomenological model suggests carbon mineralization may decrease at mid-salinities; this warrants future work into possible mechanisms for this apparent loss of function. Understanding how salinization changes community structure and ecosystem function may be paramount for managing and conserving coastal plain ecosystems where salinity is increasing due to sea level rise, saltwater intrusion, storm surges, and drought.

El artículo pretende analizar las diferencias de acceso, uso y competencia informativa, comunicacional y de gestión online de los españoles nacidos antes de 1965. Aplica un clúster con edad, sexo, estudios e ingresos, a una muestra nacional representativa, que concluye en dos perfiles. Test bivariables muestran diferencias intergrupo a favor del más joven, compuesto por más hombres, mejores ingresos y estudios, pero con más brechas internas. En unos años los mayores estarán tecnológicamente más integrados aunque deben reducirse las brechas y fomentar la participación online apostando por una comunicación digital que contribuya a estrechar la relación máquina-persona
