Hands-on tasks in CLIL science classrooms as sites for subject-specific language use and learning
2015
This paper is concerned with content and language integrated learning (CLIL), i.e. classrooms where a foreign or second language (L2) is used as the means of instruction and where content and language learning objectives merge. More specifically, it explores the potential of hands-on tasks in CLIL chemistry and physics lessons to serve as sites for using and learning subject-specific language, conceptualised as both special concepts and terminology as well as subject-specific ways of constructing meaning. Using discourse analysis, attention was directed to hands-on tasks as well as pre-task and post-task phases. The findings indicate that despite the evident content orientation in the tasks…
Partial repetitions as other-initiations of repair in second language talk: Re-establishing understanding and doing learning
2014
Abstract This conversation analytical paper examines other-initiated repair sequences in everyday interactions between first and second language speakers of Finnish. More specifically, it focuses on sequences that are initiated by a second language speaker by repeating a part of the trouble source turn and shows that the repetitions are recurrently treated as actions indicating specific language-related problems of understanding. The analysis suggests that the linguistic asymmetry in second language interactions is a resource that is drawn upon in situations in which other resources for action formation and recognition are not sufficient. In addition, the analysis illustrates why and how ce…
Análisis de la satisfacción laboral del profesorado de español como lengua extranjera (ELE)
2020
En este artículo se presentan los resultados de una investigación cuantitativa de carácter exploratorio sobre el grado de satisfacción del profesorado de ELE sobre sus condiciones laborales y perspectivas profesionales. Se discuten críticamente los datos recogidos mediante un cuestionario distribuido en línea entre 673 docentes, que mide la satisfacción en ocho dimensiones: organizativa, económica, afectiva, motivacional, discriminación, ambiente laboral, realización profesional y beneficios sociales. Los resultados permiten obtener una primera panorámica de las condiciones temporales, organizativas, económicas, sociales y psicológicas de la profesión. A pesar de algunas limitaciones relaci…
A Multi-Phase Decode-and-Forward Transmission Protocol in Cognitive Relay Networks: Outage Analysis and Relay Power Allocation
2015
Consider an underlay cognitive relay network with multiple source and destination pairs and that a decode-and-forward scheme is adopted at the relay. We propose a multi-phase transmission protocol in this paper which involves cooperation among source, relay and destination nodes. Given perfect interference elimination before decoding at the destination nodes, we derive closed-form expressions for outage probability calculation over Rayleigh fading channels. Furthermore, the optimal relay power allocation factor which leads to minimal outage probability is determined. Numerical results reveal the conditions under which satisfactory performance can be achieved based on the proposed scheme.
Hop-derived fraction rich in beta acids and prenylflavonoids regulates the inflammatory response in dendritic cells differently from quercetin: unvei…
2021
Dendritic cells (DCs) represent a heterogeneous family of immune cells that link innate and adaptive immunity and their activation is linked to metabolic changes that are essential to support their activity and function. Hence, targeting the metabolism of DCs represents an opportunity to modify the inflammatory and immune response. Among the natural matrices, Humulus lupulus (Hop) compounds have recently been shown to exhibit immunomodulatory and anti-inflammatory activity. This study aimed to evaluate the ability of specific Hop fractions to modulate DCs metabolism after stimulation with lipopolysaccharide (LPS) by an untargeted metabolomics approach and compare their effect with flavonol …
Real-time Control of Metallurgic Processes
1996
The careful control of the liquid metal solidification and the solid shell growth is of central importance in all metallurgic processes. These have a considerable influence on the formation of cracks and other defects which can be formed in the cast material. To ensure defect free products, the liquid metal is to be cooled down according to a pattern which depends i.e. on metal grade, product dimension, cooling speed and machine design. On the other hand, the control of the liquid/solid interface is a key element in optimising the liquid solidification with respect to good productivity. So, the heat transfer plays a very important role in metallurgic casting processes, especially when casti…
Analysis and Design of Induction Liquid Metal Processes Using Advanced Numerical Modelling
2019
Comprehensive knowledge of the turbulent flows, heat and mass transfer processes in the melt of induction applications is required to realize efficient metallurgical processes. Therefore, the process oriented development, design and optimization of induction furnaces for melting and casting of metals require praxis oriented simulation and analysis of the complex in-stationary turbulent melt flows and temperature distributions as well as the heat and mass transfer processes in the liquid metal. The studies, presented in this paper, demonstrate the possibilities of using advanced three-dimensional transient numerical modelling for successful simulation of the melt flow as well as heat and mas…
Technology-Enhanced Organizational Learning: A Systematic Literature Review
2019
Part 9: Learning and Education; International audience; E-Learning systems are receiving ever increasing attention in, academia, businesses as well as in public administrations. Managers and employee who need efficient forms of training as well as learning flow within the organization, do not have to gather in a place at the same time, or to travel far away for attending courses. Contemporary affordances of e-learning systems allow them to perform different jobs or tasks for training courses according to their own scheduling, as well as collaborate and share knowledge and experiences that results rich learning flow within the organization. The purpose of this article is to provide a systema…
The PHES battery does not detect all cirrhotic patients with early neurological deficits, which are different in different patients.
2017
Background and aims The psychometric hepatic encephalopathy score (PHES) is the “gold standard” for minimal hepatic encephalopathy (MHE) diagnosis. Some reports suggest that some cirrhotic patients “without” MHE according to PHES show neurological deficits and other reports that neurological alterations are not homogeneous in all cirrhotic patients. This work aimed to assess whether: 1) a relevant proportion of cirrhotic patients show neurological deficits not detected by PHES; 2) cirrhotic patients with mild neurological deficits are a homogeneous population or may be classified in sub-groups according to specific deficits. Methods Cirrhotic patients “without” (n = 56) or “with” MHE (n = 4…
Impact of LoRa Imperfect Orthogonality: Analysis of Link-Level Performance
2018
In this letter, we focus on the evaluation of link-level performance of LoRa technology, in the usual network scenario with a central gateway and high-density deployment of end-devices. LoRa technology achieves wide coverage areas, low power consumption and robustness to interference thanks to a chirp spread-spectrum modulation, in which chirps modulated with different spreading factors (SFs) are quasi-orthogonal. We focus on the performance analysis of a single receiver in presence of collisions. First, we analyze LoRa modulation numerically and show that collisions between packets modulated with different SFs can indeed cause packet loss if the interference power received is strong enough…
