Identity Use and Misuse of Public Persona on Twitter
2016
Social media sites have appeared during the last 10 years and their use has exploded all over the world. Twitter is a microblogging service that has currently 320 million user profiles and over 100 million daily active users. Many celebrities and leading politicians have a verified profile on Twitter, including Justin Bieber, president Obama, and the Pope. In this paper we investigate the '‘hundreds of Putins and Obamas phenomenon’ on Twitter. We collected two data sets in 2015 containing 582 and 6477 profiles that are related to the G20 leaders’ profiles on Twitter. The number of namesakes varied from 5 to 1000 per leader. We analysed in detail various aspects of the Putin and Erdogan rela…
Towards enabling privacy preserving smart city apps
2016
Smart city applications are increasingly relying on personally identifiable data. A disclosure of such a data to a platform provider and possible 3rd parties represents a risk to the privacy of the application users. To mitigate the privacy risk, two-layer privacy-preserving platform architecture is introduced, wherein the personally identifiable information is dealt with at the inner layer (executed in a trusted environment), whereas only generic and personally unidentifiable information is made available to the apps at the outer layer of the architecture — e.g., in a form of app-specific events. The essential requirements for the platform are described, and the architectural implications …
Performance of an asymmetric and asynchronous decode-and-forward FBMC relay system
2014
End-to-end link performance of an asymmetric and asynchronous dual-hop decode-and-forward (DF) relay system built up using a causal multirate filter bank multicarrier (FBMC) technique operated under Rayleigh fading is presented. Three main performance measures namely bit error rate (BER), outage probability and channel capacity are used for this evaluation and approximate closed-form expressions for them are also made available. FBMC setup is modeled in exact form without any approximations while customizing to one of the most efficient subcarrier filter. Simulations are carried out in quasi-static multipath fading channels under symmetric, asymmetric, synchronous and asynchronous condition…
Homing blogs as ambivalent spaces for feminine agency
2017
This article discusses a form of lifestyle blogging where women blog about their homes and everyday lives. In these homing blogs, selfrepresentations are characteristically spatially demarcated within the private sphere of the home. As these repeated representations of women in their homes take place in the public space of the internet, homing blogs work towards naturalizing the home as a women’s sphere. Written and commented on mostly by other women, homing blogs represent a feminine form of self-expression and communication that functions as a discursive expression of ongoing social, economic, and cultural changes in affluent Western societies. In this article, Finnish versions of these h…
International artists-in-residence 1990-2010 : mobility, technology and identity in everyday art practices
2016
Considering the exponential growth of artistic residencies between 1990 and 2010 at an international level, artists working in associated mobility programmes have been challenged by unsettled transnational working practices and competition. This, in turn, provides them with the opportunity to develop their creative processes. It is shown that artists’-in-residence openness and willingness to travel internationally is, on the one hand, related to the development of information technology, and on the other, supported by travelling facilities, which have impact on lifelong learning and cultural maintenance. Whereas change of geographical environment is often associated to psychological and phy…
Explaining classroom teachers’ attitudes towards inclusive education
2019
Teacher attitudes have been identified as an important resource when striving towards inclusive education as defined in the Salamanca Statement (1994). This study surveyed some key factors associated with teacher attitudes towards inclusion. The participants were 1,456 classroom teachers in Finnish primary schools who were asked about their readiness to include in their classrooms a student with a specified special educational need (SEN). The results were reviewed in association with some background variables, including workload concerns, evaluation of professional skills and the opportunity to get extra support if needed. The results show that classroom teachers’ positive attitudes towards…
Rúbricas para evaluar la influencia de las TIC en el proceso de enseñanza/aprendizaje : estudio de caso en Educación Secundaria
2019
espanolUtilizar las Tecnologias de la Informacion y de la Comunicacion (TIC) en las aulas de Educacion Secundaria contribuira a un aprendizaje mas efectivo para el adolescente en materias cientifico-tecnicas; asi como, la utilizacion de rubricas para evaluar su ensenanza esta considerado un instrumento eficaz para cuantificar dicho proceso. En este sentido, la experiencia de investigacion-accion que aqui se presenta fue desarrollada en un instituto de Educacion Secundaria de Valencia, en la materia de Biologia-Geologia. El objetivo de esta experiencia se centro en valorar la influencia de las TIC en el proceso de ensenanza/aprendizaje de esta asignatura, mediante rubricas de evaluacion. Se …
Las citas como práctica del uso de las fuentes : las citas de fuentes en línea seleccionados por los estudiantes en sus trabajos
2020
This study examined upper secondary school students’ citations of self-selected online sources in their essays. Students (n = 140) conducted online inquiry about either effects of social media on people’s quality of life (SM) or allowance of genetic manipulation of organisms (GMO). Students, working either individually or in pairs, explored online sources with the help of a graphic organizer, after which they composed their essays. To capture the quality of citations identified in the essays, they were evaluated in terms of accuracy and richness of source features. Further, regression analysis was used to examine the effect of topic, grade level and work mode on the number and quality of ci…
Protección de la infancia y nuevas tecnologias de la comunicación : el código PEGI de regulación de los videojuegos y juegos on-line
2008
Monográfico con el título: 'Videojuegos: una herramienta en el proceso educativo del 'Homo Digitalis''. Resumen basado en el de la publicación Se dice que el futuro de un pueblo reside en sus hijos, y no sólo porque ellos son el futuro, sino porque este es mejor si protege y educa bien a sus niños. Ya en 1959 la Organización de las Naciones Unidas redactó diez principios en la Declaración de los Derechos del Niño. El segundo de estos principios afirma que 'el niño gozará de una protección especial para que pueda desarrollarse física, mental, moral, espiritual y socialmente'. En el siglo XXI, en un contexto de sociedad del conocimiento muy diferente al de 1959, el derecho a la protección deb…
