Project DyAdd: Non-linguistic Theories of Dyslexia Predict Intelligence
2020
Two themes have puzzled the research on developmental and learning disorders for decades. First, some of the risk and protective factors behind developmental challenges are suggested to be shared and some are suggested to be specific for a given condition. Second, language-based learning difficulties like dyslexia are suggested to result from or correlate with non-linguistic aspects of information processing as well. In the current study, we investigated how adults with developmental dyslexia or ADHD as well as healthy controls cluster across various dimensions designed to tap the prominent non-linguistic theories of dyslexia. Participants were 18–55-year-old adults with dyslexia (n = 36), …
Investigation of data encryption impact on broadcasting visible light communications
2014
Este trabajo investiga el impacto de la encriptación y desencriptación de datos en un sistema de comunicaciones de luz visible (VLC) de difusión en interiores incrustado en la capa física. Se ha implementado el cifrado RSA para proporcionar una transmisión de datos segura en la capa física. El artículo muestra el rendimiento de la tasa de error de bits (BER) para los sistemas VLC seguros y no seguros (8 y 12 bits) para velocidades de datos de 2 y 12 Mbps. Para una BER de 10e-4 mostramos que hay penalizaciones de potencia de 2-4 dB con las VLC seguras. También se investiga el impacto de la longitud de la clave en la propagación del error y la penalización de potencia. EU Cost Action IC1101 T…
The Role of Big Data in Addressing Societal Challenges: A Systematic Mapping Study
2019
Part 2: Big Data Analytics; International audience; Big data has recently become the focus of academic and corporate investigation due to its high potential in generating business and social value. We have done a systematic mapping of the literature related to big data and its applications leading to social change through the lens of social innovation. The search strategy initially resulted in 593 papers, and after applying inclusion exclusion criteria a total of 156 papers were mapped; 59% of which were identified as empirical studies. This mapping investigated the publication frequency of the studies, research approach and contributions, research areas and article distribution per journal…
Work team effectiveness in organizational contexts
2005
PurposeThis introductory paper aims to provide a contextualization of recent research and applications on work team effectiveness in organizational contexts carried out in Spain and Portugal and to describe connections between this research and the main trends in the international scene.Design/methodology/approachSince the 1990s, new occupational and organizational realities have deepened scientific interest in work teams in both Spain and Portugal. A range of recently published (1992‐2004) works in this area are reviewed. The selected sources are papers published in Spanish, Portuguese and international journals.FindingsReviewing this work, four major trends are identified that synthesize …
Applying the Identity Status Paradigm to Managers’ Moral Identity
2019
We investigated the applicability of the identity status paradigm in identifying different stages of moral identity maturity among managers, focusing on how they solve moral conflicts in the context of work. Researchers conducted two theory-driven studies. Study 1 was based on focus group discussions among 16 managers, while Study 2 was based on open-ended questionnaire items from 180 managers. Both studies supported the hypothesized identity statuses. The status named diffusion included a lack of commitment to moral values and associated with avoiding moral questions at work. In foreclosure, extrinsic (e.g., organizational) values were adopted and applied to personal decision-making. Manag…
Agency, expertise and working life skills : Students’ conceptions of the generic competences required in the world of work
2021
Fundamental changes in working life highlight the demands on the co-operation between the educational sector and working life, that should contribute to students’ employability. In addition to discipline-specific expertise, the development of working life skills has received increasing attention when it comes to employment. Drawing on data from Finnish universities of applied sciences (n=5) and universities (n=3), this paper examines how students (n=380) value the generic competences needed in in the world of work. The study is based on European reforms of labour markets and educational structures. This paper adds to current discourses around employability by highlighting differences betwee…
Female knowledge workers and the illusion of working-time autonomy
2017
Purpose The purpose of this paper is to ask: what are the temporal realities of female knowledge workers? It especially focusses on women’s possibilities of using working-time autonomy, and the work and non-work practices that shape their possibility to use work-hour autonomy. In knowledge work, working-time autonomy is usually high, but exercising autonomy is not always possible. The study was carried out in Finland, where full-time work is common also among women, even if they have small children. Design/methodology/approach The data include 19 semi-structured interviews of women who have knowledge-intensive work. The method of analysis is problem-driven content analysis. Findings Female…
BEGIN: Big Data Enabled Energy-Efficient Vehicular Edge Computing
2018
Vehicular edge computing is essential to support future emerging multimedia-rich and delay-sensitive applications in vehicular networks. However, the massive deployment of edge computing infrastructures induces new problems including energy consumption and carbon pollution. This motivates us to develop BEGIN (Big data enabled EnerGy-efficient vehIcular edge computiNg), a programmable, scalable, and flexible framework for integrating big data analytics with vehicular edge computing. In this article, we first present a comprehensive literature review. Then the overall design principle of BEGIN is described with an emphasis on computing domain and data domain convergence. In the next section, …
Privacy-preserving scheme for mobile ad hoc networks
2011
This paper proposes a decentralized trust establishment protocol for mobile ad hoc networks (MANETs), where nodes establish security associations. In order to achieve privacy and security, we use homomorphic encryption and polynomial intersection so as to find the intersection of two sets. The first set represents a list of recommenders of the initiator and the second set is a list of trusted recommenders of the responder. The intersection of the sets represents a list of nodes that recommend the first node and their recommendations are trusted by the second node. In our experimental results we show that our scheme is effective even if there are 30 trusted nodes.
Toward a lightweight and efficient UAV‐aided VANET
2019
International audience; Connectivity in a smart vehicular network is quite sensitive and highly affected by its dynamic network topology. Issues related to the intermittent nature of connectivity may arise due to the high mobility of nodes and network heterogeneity. In sparse areas, a vehicular network is basically a disruption‐tolerant network suffering from frequent disconnections, long delays, and messages loss. Facing these issues, and specifically for time‐sensitive applications, Unmanned Aerial Vehicle (UAV) can provide valuable assistance to Vehicular Ad Hoc Network (VANET) by assuming a relay node role between disconnected segments in the road. In such scenarios, effective communica…
