Emergency Distance Education (EDE), Urgent Transition to Distance Learning from the Perspective of UAE University Teachers

To combat the spread of COVID-19, education systems around the world were facing an unprecedented challenge of mass university closures. This research attempts to analyze this sudden and urgent transition to Distance Learning, which was a new experience for 93.9% of UAE university teachers. We have called this urgent situation “Emergency Distance Education”, to which we have given a definition. A survey was conducted among 240 teachers to express their opinion on this new way of teaching, and to answer a set of questions, such as: what were their main challenges? did they provide theoretical courses in the same way as practical courses? and what do they suggest as future solutions for best practices in Distance Learning? As result, we found three categories of challenges raised by the respondents, namely: Pedagogical, Technical, and Interaction problems. The results of this study show that the greatest number of teachers were suddenly transferred to Distance Education without having previous experience. And the most notable suggestion made by more than 60% of teachers, and which could be an open path to a new field of study, is that the measure of a credit hour in Distance Education compared to that in face-to-face must be reviewed

Community detection and role identification in directed networks: understanding the Twitter network of the care.data debate

With the rise of social media as an important channel for the debate and discussion of public affairs, online social networks such as Twitter have become important platforms for public information and engagement by policy makers. To communicate effectively through Twitter, policy makers need to understand how influence and interest propagate within its network of users. In this chapter we use graph-theoretic methods to analyse the Twitter debate surrounding NHS Englands controversial care.data scheme. Directionality is a crucial feature of the Twitter social graph - information flows from the followed to the followers - but is often ignored in social network analyses; our methods are based on the behaviour of dynamic processes on the network and can be applied naturally to directed networks. We uncover robust communities of users and show that these communities reflect how information flows through the Twitter network. We are also able to classify users by their differing roles in directing the flow of information through the network. Our methods and results will be useful to policy makers who would like to use Twitter effectively as a communication medium

An Evolutionary Approach for Learning Opponent's Deadline and Reserve Points in Multi-Issue Negotiation

The efficiency of automated multi-issue negotiation depends on the available information about the opponent. In a competitive negotiation environment, agents do not reveal their parameters to their opponents in order to avoid exploitation. Several researchers have argued that an agent's optimal strategy can be determined using the opponent's deadline and reserve points. In this paper, we propose a new learning agent, so-called Evolutionary Learning Agent (ELA), able to estimate its opponent's deadline and reserve points in bilateral multi-issue negotiation based on opponent's counter-offers (without any additional extra information). ELA reduces the learning problem to a system of non-linear equations and uses an evolutionary algorithm based on the elitism aspect to solve it. Experimental study shows that our learning agent outperforms others agents by improving its outcome in term of average and joint utility

One step protocol and green synthesis of 2-N,N-dimethylamino-3-alkyl(aryl)-2-oxido-1- hydro-2-benzo[1,3,2]diazaphosphinine-4-one derivatives

ABSTRACT. 2-N,N-dimethylamino-2-oxido-3-alkyl(aryl)-1-hydro-2-benzo[1,3,2]diazaphosphinin-4-one (2) derivatives  are synthesized by one pot reaction by reacting equimolar quantities of anthranilic acid, primary amine, and N,N-dimethylphosphoramic dichloride under reflux of ethanol with good yields. The structure of the compounds were established on the basis of their infrared, nuclear magnetic resonance spectral data (1H NMR, 13C NMR and 31P NMR), mass spectrometry, and elemental analysis.   KEY WORDS: Anthranilic acid, N,N-Dimethylphosphoramic dichloride, Diazaphosphinine Bull.

Behaviour and evolution of quartzites in detrital accumulations

[Resumen] La presente nota trata de los caracteres y del proceso evolutivo que ofrecen las cuarcitas areniscosas en depósitos detríticos localizados en cuencas-vertientes fluviales y en acumulaciones playeras. La abundancia de este tipo de material en formaciones actuales y antiguas de los valles del Moucide, Xunco y Cabo, desde Cangas de Foz a San Cibrán (Norte de Lugo), ha permitido un estudio estadístico, en términos de actividad morfogenética y textura de los diferentes grupos dimensionales. Ofreciéndose, asimismo, un diagrama-resumen del comportamiento de este material en los diferentes tipos de depósitos.[Abstract] This paper deals with the characteristics and evolution process of quartzites (low Candena quartzites) from detrital deposits of fluvial basics and beach acumulations.The present and past sedimentary formations from Moucide, Xunco and Cobo basics (nord of Lugo, Spain) from Cangas de Foz to San Cibrián are plenty in this. Kind of deposits. That permit us, an statistical analysis-from the point of wiew of texture and morphogenesis, and the study of quartzite behaviour in different types of deposit

Estudio de la dinámica sedimentaria de la Laguna costera del Sur de Túnez (Túnez, Mar Mediterráneo)

The South lagoon of Tunis, a shallow Mediterranean lagoon, had undergone an important restoration management (during the period 1998-2001), leading to structural and functional changes of this coastal ecosystem. In this work, a comprehensive study of sedimentary dynamic based on hydrodynamic data, granulometric analysis, mineralogy and impact evaluation is presented. Restoration project, especially the establishment of two groups of inlets gates of the channel of Rades and Tunis (recalibrated during the restoration management), imposed an east-west water flow direction, created from high tide submersion, with an average flow exchanged with the sea about 80 m3s-1. This current control local sediment sorting. The grain sizes analysis of superficial sediment shows that the lagoon bottom characterized by fine sediments ( < 63 μm, 50-90%). The sediment dynamic is controlled by the lagoon water currents inducing an east-west grain-size sorting. The extreme eastern side of the lagoon, close to the inlet gate, is lined by medium sand, moderately sorted and transported by saltation. The central and western sides of the lagoon are covered by fine sand, poorly sorted, and deposed in relatively calm hydrodynamic conditions. Mineralogical results reveal the following association: quartz (13 to 69%), biogenic calcite, (15 to 81%), aragonite (0 to 8%), pyrite (0 to 1,75%) and accessory magnetite, smectite, illite and kaolinite. The lagoon seems to be a protected zone as a result of restoration project that forms a physical barrier for sedimentary materials amount from Gulf of Tunis.La laguna sur de Túnez, una laguna costera mediterránea poco profunda, se sometió a importantes trabajos de restauración durante el período 1998-2001, lo que ha llevado a cambios estructurales y funcionales de este ecosistema costero. En este trabajo se presenta un estudio integral de dinámica sedimentaria basado en datos hidrodinámicos, análisis granulométrico, mineralogía y evaluación de impacto. El proyecto de restauración, especialmente el establecimiento de la puerta de entrada de los canales de Rades y Túnez, impuso una dirección de flujo de agua este-oeste controlando la clasificación local de sedimentos. El análisis de tamaño de grano del sedimento superficial muestra que el fondo de la laguna está revestido por sedimentos finos
