An eye tracking comparison of external pointing cues and internal continuous cues in learning with complex animations

2010

Abstract Two experiments used eye tracking to investigate a novel cueing approach for directing learner attention to low salience, high relevance aspects of a complex animation. In the first experiment, comprehension of a piano mechanism animation containing spreading-colour cues was compared with comprehension obtained with arrow cues or no cues. Eye tracking data revealed differences in learner attention patterns between the different experimental conditions. The second experiment used eye tracking with synchronized and non-synchronized cues to investigate the role of dynamic direction of attention in cueing effectiveness. Results of Experiment 1 showed that spreading-colour cues resulted…

Community Currencies (CCs) in Spain: An empirical study of their social effects

2016

Despite its sudden proliferation along the economic crisis period, no previous study has investigated the social effects of the community currency (CCs) experiences in Spain. Previous research on CCs experiences from different countries provided evidences about social capital improvement, introducing CCs as sustainability tools. This research uses the theoretical frameworks of social capital and complex adaptive systems to approach concepts like sustainability, networks, trust, norms, participation and cooperation. Statistical analysis of the data collected in June 2013 through online survey explores social capital and resilience indicators among the Spanish exchange community users, conclu…

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…

“Pursuing Community Resilience through Outcome-Based Public Policies: Challenges and Opportunities for the Design of Performance Management Systems”

2017

The purpose of this symposium is to contribute to the ongoing debate on this topic in the public administration literature by exploring the contribution of performance management in the implementation of effective governance systems that may foster community resilience, especially to social “wicked” problems. The set of articles hosted in this issue provides a variegated mix of ideas and experiences in this field, encompassing different countries (from Northern to Southern Europe, and Canada), sectors (including labor, healthcare, tourism, and public utilities), and methodological approaches. An empirical perspective is adopted by the authors, involving case studies, interviews, and field r…

The Development of Resilience Management Guidelines to Protect Critical Infrastructures in Europe

2018

The capability to be resilient in the face of crises and disasters is a topic of highest political concern in Europe especially as far as critical infrastructures and urban environments are concerned. Critical infrastructures are systems or part of systems essential for the maintenance of vital societal functions, the disruption or destruction of which would have a significant impact on the well-being of people. Examples of them are transportation services, energy infrastructures, water and wastewater systems, health and emergency services, financial services, communication infrastructures, etc. The symposium focuses on the experience of four different projects funded under the Horizon 2020…

The Transcultural Community Resilience Scale: Psychometric Properties and Multinational Validity in the Context of the COVID-19 Pandemic

2021

Few instruments assess community resilience. In the midst of the COVID-19 pandemic, the capacity of communities to support resilience of members deserves to be assessed to develop programs for improving mental health of affected populations. This article presents the development of the Transcultural-Community Resilience Scale (T-CRS), its underlying factorial structure and transcultural validity with a multilingual (English, French, Creole, Kinyarwanda), multinational (DR Congo, Haiti, Rwanda, Togo) and multicultural sample affected by this pandemic. A sample of 1,267 participants (40.9% women) were recruited in the four countries: DRC (n = 626, 43.4% women), Haiti (n = 225, 42.0% women), R…

A grid representation for distributed virtual environments

2004

Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environments (DVE) very common nowadays. The architecture and behavior of these systems are very similar to new grid computing applications where concepts such as sharing and high scalability are extremely exploited. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective DVE system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the arbiters (servers) in the system. As an alternative to the ad-hoc heuristic proposed in the l…

Effective strategies for targeted attacks to the network of Cosa Nostra affiliates

2022

AbstractNetwork dismantling has recently gained interest in the fields of intelligence agencies, anti-corruption analysts and criminal investigators due to its efficiency in disrupting the activity of malicious agents. Here, we apply this approach to detect effective strategies for targeted attacks to Cosa Nostra by analysing the collaboration network of affiliates that participate to the same crimes. We preliminarily detect statistically significant homophily patterns induced by being member of the same mafia syndicate. We also find that links between members belonging to different mafia syndicates play a crucial role in connecting the network into a unique component, confirming the releva…

Too Much or Too Little Messaging? Situational Determinants of Guilt About Mobile Messaging

2021

Abstract Mobile messaging has been associated with guilt. Guilt about too much messaging may result from self-control failures during goal conflicts. Conversely, guilt about too little messaging may result from violating the salient norm to be available. This research considers both boundary conditions of guilt about mobile communication—goal conflicts and availability norm salience—simultaneously for the first time. We conducted two preregistered experiments to investigate their interplay. Results from a vignette experiment, but not from a laboratory experiment, support the hypotheses that goal conflicts trigger guilt about using messengers and that guilt about not using messengers arises …
