CSCL – a tool to motivate foreign language learners: The Finnish application
2003
This article discusses the applications of the theory of Computer Supported Collaborative Learning (CSCL) to teaching and learning a foreign language, in this case, one of the ‘Less Commonly Taught Languages’, Finnish. The ‘Virtually Finnish’ project was based on the idea of creating a larger, virtual Finnish learning community among the second-year Finnish language students in five US universities during the fall semester, 2001. CSCL was chosen as a base, as its principal goal is to aid the learners in sharing and distributing their knowledge to the whole learning community. In addition to discussing the set up and the content of the project, the students’ feedback about their language lea…
MODULAR KNOWLEDGE REPRESENTATION IN ADVISOR AGENTS FOR SITUATION AWARENESS
2011
A modular knowledge representation framework for conversational agents is presented. The approach has been realized to suit the situation awareness paradigm. The modularity of the framework makes possible the composition of specific modules that deal with particular features, simplifying both the chatbot design process and its smartness. As a proof of concepts we have developed a modular, situation awareness oriented, KB for a conversational agent, which plays the role of an advisor aimed at helping a user to be in charge of a virtual town, inspired to the SimCity series game. The agent makes an extensive use of semantic computing techniques and is able to perceive, comprehend and project c…
Understanding dynamic scenes
2000
We propose a framework for the representation of visual knowledge in a robotic agent, with special attention to the understanding of dynamic scenes. According to our approach, understanding involves the generation of a high level, declarative description of the perceived world. Developing such a description requires both bottom-up, data driven processes that associate symbolic knowledge representation structures with the data coming out of a vision system, and top-down processes in which high level, symbolic information is in its turn employed to drive and further refine the interpretation of a scene. On the one hand, the computer vision community approached this problem in terms of 2D/3D s…
Online Intercultural Dialogue: “Failed” Communication in a Telecollaboration Project
2021
Over the past two decades, the development of computer-mediated communication technologies has modified human communication. Increasingly, representatives from diverse linguistic and cultural backgrounds are disposed to a constant negotiation of meanings. The main purpose of this study is to carry out a linguistically grounded analysis of the intercultural dialogue during online asynchronous written exchanges between Latvian and Cypriot students.Based on the politeness theory of Brown and Levinson (1987), which implies that all adult members of society are endowed with two universal aspects: “positive face” and “negative face”, and using the methods of content analysis and discourse analysi…
The polycontextual nature of computer-supported learning – theoretical and methodological perspectives
2003
This article discusses some theoretical and methodological problems and issues in the study of computer-supported learning activities with special reference to a discourse perspective in research. Special emphasis is laid on finding ways to reach the participant perspective in computer-supported collaborative learning projects, which are by nature polycontextual. By this term we refer to the diverse scenes and situations of learning activities that computer-supported learning involves. We will also address the issue of making claims on effective pedagogies, leaning on the theory of discourse as situated and constructive, which again sets special requirements on what kinds of assumptions and…
Convencer mirando a cámara: el minuto de oro de los debates electorales como refugio de condensación retórica
2021
This paper studies the final statements (“golden minutes”) of televised electoral debates in Spain between 1993 and 2019. The methodology is adjusted to the cognitive analysis of discourse, analyzing three pragmatic indicators that could reveal an evolution in three stages of Spanish politics: the bipartisan phase (1993-2011), an adjustment phase (2011-2015) and a multiparty phase (2015- 2019). The discursive spaces dependent on the predicative strategy, the predominant illocutionary force, and the use of superstructures are analyzed. It is concluded that, for the three phases, the variables referring to the use of enunciative persons (which points to the introduction of the ethos of discou…
Defending either a personal or an assigned standpoint
2018
Abstract This study clarifies whether a specific type of role play supports upper secondary school students’ collaborative argumentation. Data consist of 12 dyadic face-to-face and 12 chat debates. Data analysis focused on the quality of students’ argumentation. Comparisons were made between students who defended standpoints at variance with their personal opinions on the topics, between the two study modes and topics, and by gender. When the students defended a standpoint differing from their personal opinion, the male students engaged in counterargumentation more often than the female students. When, in turn, the students defended their personal standpoint, they produced both counterargum…
Changing the ownership of ideas: Multimedial accomplishment of collaborative reflection in an organizational workshop
2022
Reflecting on work processes together with one's co-workers is becoming increasingly important in workplaces. This study examined collaborative reflection in the organizational context through analyzing a case of a complex workplace setting where an enterprise social media platform, talk-in-interaction, and handwriting were used to engage participants in the process of reflection. Drawing on the concept of remediation, the results show that collaborative reflection is interactionally accomplished through a multimedial activity chain, in which the ownership of presented ideas is transformed from individual ideas into shared views of the team. The study shows in detail how the process of coll…
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…
The use of cultured hepatocytes to investigate the metabolism of drugs and mechanisms of drug hepatotoxicity.
2001
Hepatotoxins can be classified as intrinsic when they exert their effects on all individuals in a dose-dependent manner, and as idiosyncratic when their effects are the consequence of an abnormal metabolism of the drug by susceptible individuals (metabolic idiosyncrasy) or of an immune-mediated injury to hepatocytes (allergic hepatitis). Some xenobiotics are electrophilic, and others are biotransformed by the liver into highly reactive metabolites that are usually more toxic than the parent compound. This activation process is the key to many hepatotoxic phenomena. Mitochondria are a frequent target of hepatotoxic drugs, and the alteration of their function has immediate effects on the ene…
