A note on the exterior centralizer
2009
The notion of the exterior centralizer \({C_G^{^\wedge}(x)}\) of an element x of a group G is introduced in the present paper in order to improve some known results on the non-abelian tensor product of two groups. We study the structure of G by looking at that of \({C_G^{^\wedge}(x)}\) and we find some bounds for the Schur multiplier M(G) of G.
Towards artificial intelligence : advances, challenges, and risks
2019
This text contains some reflections on artificial intelligence (AI). First, I differentiate between strong and weak AI, as well as the concepts related to general and specific AI. Following this, I briefly describe the main current AI models and discuss the need to provide common-sense knowledge to machines in order to advance towards the goal of a general AI. Next, I talk about the current trends in AI based on the analysis of large amounts of data, which has recently allowed experts to make spectacular progress. Finally, I discuss other topics which, now and in the future, will continue to be key in AI, before closing with a brief reflection on the risks of AI.
Communication Design for the Dissemination of Scientific Knowledge. Languages, Tools, Technologies, Collaborative Processes for Museum Education
2019
Il testo propone l’analisi di un articolato processo di ricerca-azione, avviato in occasione di alcune sperimentazioni didattico-scientifiche nate dalla collaborazione tra le discipline del design, della rappresentazione multimediale, delle scienze botaniche nell’Università di Palermo. L’esperienza proposta è stata centrata sulla comunicazione scientifica e sull’elaborazione di prodotti comunicativi per la didattica museale e istituzionale dell’Orto Botanico di Palermo. In quest’occasione sono stati sperimentati strumenti progettuali, tecnologie e modalità di espressione successivamente rielaborati anche in un progetto di sviluppo territoriale, che ha portato alla realizzazione del “Micromu…
Listening understanding and acting (lung): focus on communicational issue in thoracic oncology.
2019
Background: In the field of oncological assistance, nowadays we have to deal with a complex scenario where patients got used to obtain a huge amount of information through internet or social media and to apply them in performing their health-related decisions. This landscape requires that clinicians become able to handle therapeutical approaches and adequate skills in communication tools to satisfy the current needs. Our project aimed to build a communication model based on clinical oncologists’ real experiences in order to find a simple way to share with patients all the innovative therapeutical opportunities today available in lung cancer. The final goal is to design a flexible and person…
The ecosystem of the foreign language learner : selected issues
2015
This volume examines selected aspects of the foreign language learning process from an ecological perspective, adopting a holistic view on complex interrelations among and within organisms (L2 language learners) and their milieus (family, school and society). First of all, the personal ecosystem of the learner is taken into consideration, whereby two powerful influences are intertwined: cognitive and affective aspects. The learning space formed by the individual is largely shaped by their affective states coexisting in conjunction with their cognitive processes. Moreover, this specific space is also modified by a wider array of other personal ecosystems or those of cultures. Hence, the ecos…
Effective Teacher Training: Teacher Lectures in Comparison with Student Power Point Presentations
2013
National (dispositions of the Ministry of Education in Poland 2004, 2006) and international (Common European Framework of Reference for Languages 2001) documents provide many guidelines and suggestions about the competencies that foreign language teachers of today should develop to meet the desired standards and obtain the necessary qualifications. These qualifications comprise knowledge and a wide range of skills. The focus of this chapter is on knowledge since it is the foundation for the development of teaching skills and of a reflective approach to one’s teaching practices. In Polish tertiary education institutions the so-called “theoretical knowledge” has been imparted by means of lect…
La didactique clinique comme mode d’accès aux savoirs des enseignants en ÉPS : le cas de l’enseignement du judo
2018
Cette étude à visée exploratoire et compréhensive met en évidence les savoirs personnels des enseignants transmis en cours d’ÉPS. La recherche présente trois vignettes didactiques cliniques d’enseignants spécialistes de judo. Les résultats montrent que ces savoirs personnels se sont construits pendant la pratique sportive du judo lorsque ceux-ci étaient de jeunes pratiquants. Le rôle du « déjà-là expérientiel » et ses effets sur les conceptions des professeurs sont mis en avant, en lien avec les savoirs personnels. Compte tenu des effets déterminants des « déjà-là expérientiels et conceptuels », nous proposons quelques pistes de travail pour la formation initiale des enseignants d’ÉPS.
Collaborative Policy Making and Stakeholder Engagement: A Resident–Based Perspective
2019
This study analyses residents’ perceptions and attitudes towards tourism and community engagement with tourism planning. Overall, residents think that the positive effects of tourism development outweigh the negative impacts. Despite this, they express concerns regarding the economic future of their area and that the tourism development in their area is mostly exogenously driven. Further, they do not feel involved in tourism planning but, quite surprisingly, they do not seems to be convinced that local authorities should encourage community participation in tourism decision making. Exploratory factor analysis and hierarchical and non-hierarchical cluster analysis were therefore conducted. F…
Community Resilience in Crises : Technology and Social Media Enablers
2014
Technology can contribute greatly to disaster resilience, especially by enhancing the interconnectedness between the authorities and the public and by facilitating the rapid exchange of information. This special issue of Human Technology: An Interdisciplinary Journal on Humans in ICT Environments is focused on technology and social media enablers of community resilience. Crises take on a variety of shapes and forms—natural or health disasters, terroristic and criminal acts, technology malfunctions, and large-scale accidents—at the local, regional, national, and global levels. Crisis management plans, created and implemented at the organizational level, typically involve public service and i…
Mobile social networking in theory and practice
2008
Mobile social networks have gained the attention of the media, academy and mobile market. Despite of the robust tradition of network and community studies, mobile social networks are often addressed improperly. This paper presents a theoretical framework to study mobile social networking and examines the design implications of results of an exploratory study conducted with a group of 18 young adults in Finland. The findings of this study indicate that the quality of mobile applications offering social networking could be greatly increased by integrating the knowledge of two traditions that so far developed in parallel, namely the mathematical as well as social approaches to social networks.
