Introduction to Expanding Universes : Exploring Games and Transmedial Ways of World-building
2018
Transmedia is a wide concept, as by definition, it is a network of various media forms. It includes also games, both digital and more traditional forms of games. Transmedia productions are often built around a certain television series, but in some cases a digital game has been the core production as well. Games, however, have not been looked at in detail in their role as a part of a transmedia whole. It is important to pay attention to the specificity of games as a media form, to their product-audience relation, and to the way how they incorporate playfulness into that relation. Even in cases where games are just a minor part of the production, the playfulness involved in transmedia user p…
The Rally Course : Learners as co-designers of out-of-classroom language learning tasks
2019
This chapter introduces a “Rally Course” as a novel CA-inspired approach to teaching a second language. This approach builds on an understanding of language learning as a social process that is closely intertwined with L2 speakers’ evolving membership in the surrounding community. It addresses the need to develop experiential pedagogies that widen learners’ opportunities for interaction and support the socialisation process. Building on recent pedagogical initiatives supporting language learning in the wild, we illustrate the overall structure of the Rally Course, describe the main materials that were designed to support the learning objectives and present a case analysis of a student carry…
‘Sociability before individuality’: lesson structure in lower secondary classrooms
2018
This paper contributes to the research field of classroom research by offering an empirical analysis of classroom instruction on the level of lesson structure. The research questions are: What are ...
Deducing the USLE mathematical structure by dimensional analysis and self-similarity theory
2010
The Universal Soil Loss Equation (USLE) was originally deduced by a statistical analysis of a large data set of soil loss measurements. The multiplicative structure of the model has been criticised due to the considerable interdependence between the variables. Using the soil erosion representative variables and the reference condition adopted in the USLE, the aim of this paper was to apply dimensional analysis and self-similarity theory to deduce the functional relationship among the selected variables. The analysis yielded a multiplicative equation, similar to the USLE. Therefore, this study suggested that the USLE has a logical structure with respect to the variables used to simulate the …
Testing a hierarchical and integrated model of quality in the service sector: functional, relational, and tangible dimensions
2009
Prior research has revealed limitations of the dominant SERVQUAL model of service quality. Some authors have pointed out the SERVQUAL model somewhat neglects the tangible and relational facets of quality in the service sector, and, therefore, there is a need to obtain a comprehensive and adaptable structure of quality for different types of services. Consequently, we propose and test a hierarchical and integrated model of service quality, hypothesising the existence of three second-order dimensions: functional quality (describing the efficiency with which the service core is provided); tangibles (the quality of physical service environment); and relational quality (relational or emotional b…
Participación asociativa percibida en contextos socio-educativos: validación de contenido
2019
En las asociaciones del Tercer Sector de acción socioeducativa se han ido estableciendo lógicas, políticas y prácticas para acreditar la calidad de los servicios. Este tipo de orientaciones organizativas son similares a los procedimientos que se han llevado a cabo en los últimos años, en otros contextos educativos, y que han mermado considerablemente la participación real y eficaz de los principales agentes implicados. A ello se suma la falta de estándares para evaluar la participación asociativa percibida. Atendiendo a esta problemática, nos planteamos el objetivo de establecer unos indicadores válidos que permitan registrar la perspectiva de los socios y los profesionales acerca de su par…
Researches Regarding the Use of Fuzzy Controllers within CNC Feed Drives
2015
This paper presents some simulation based upon a dynamic model of a feed-drive within the structure of a CNC machine tool. A DC servomotor was considered as actuation device for the feed drive. For a given set of parameters for the position controller, two fuzzy types of fuzzy controllers were tested by means of simulation. The first fuzzy controller was a proportional one, with one input and one output, while the second one was a two variables one, with two inputs and one outputp.
Autonomic behaviors in an Ambient Intelligence system
2014
Ambient Intelligence (AmI) systems are constantly evolving and becoming ever more complex, so it is increasingly difficult to design and develop them successfully. Moreover, because of the complexity of an AmI system as a whole, it is not always easy for developers to predict its behavior in the event of unforeseen circumstances. A possible solution to this problem might lie in delegating certain decisions to the machines themselves, making them more autonomous and able to self-configure and self-manage, in line with the paradigm of Autonomic Computing. In this regard, many researchers have emphasized the importance of adaptability in building agents that are suitable to operate in real-wor…
Physical simulation for real-time image/video retargeting
2012
Retargeting methods present content on arbitrary aspect ratio me- dia displays limiting distortions in relevant objects. This is done by means of applying non-homogeneous resizing operators across the whole media, constraining it to fit into the required size. Several succesful systems have been proposed to achieve image retargeting, while video retargeting is still challenging due to time consistency and computational complexity requirements. Two important con- tributes were proposed: non-homogeneous retargeting [Wolf et al. 2007] and improved seam-carving [Rubinstein et al. 2008]. The first one claims to achieve real-time performance but considers spa- tial coordinates separately. The lat…
TeamSim: An Educational Micro-World for the Teaching of Team Dynamics
2008
In this paper we present an educational micro-world in which a learner can manipulate variables affecting the efficiency with which a team adapts to its environment. These include the structure of hierarchical relations within the team, the structure of the communications network, and other environmental parameters. Using the micro-world, the learner can design experiments (simulations) exploring notions in the dynamics of small groups. A freeware version of TeamSim is available from http:// laral.istc.cnr.it/gigliotta/.
