Nature Inspired Scenes for Guided Mindfulness Training: Presence, Perceived Restorativeness and Meditation Depth
2019
Practicing mindfulness-based stress reeducation and other contemplative practices generates a number of health and human performance benefits. However, limited access to qualified training and practice support, as well as poor practice environments, makes it difficult to sustain the habits necessary to develop the attentional regulation skills needed to benefit from mindfulness. In this paper, we report on our research, which focuses on developing immersive environments to support mindfulness-based stress reduction practices. We specifically look at how the design of a virtual environment can foster a restorative experience, if that restorative experience is associated with the depth of the…
The Adoption of New Treatment Modalities by Health Professionals and the Relative Weight of Empirical Evidence in Favor of Virtual Reality Exposure V…
2020
Anxiety disorders are among the most prevalent mental disorders, and cognitive-behavioral therapy (CBT) with exposure exercises is considered as the gold-standard psychological intervention. New psychotherapeutic modalities have emerged in the last decade and, among them, mindfulness has been rapidly adopted by therapists. The adoption rate is slower for the use of virtual reality (VR) to conduct exposure. The goal of the present position paper is to contrast, for the treatment of anxiety disorders, the weight of empirical evidences supporting the use of exposure in VR with the use of mindfulness-based therapy (MBT). Based on the most recent meta-analyses, we found that CBT with exposure co…
Being in the Past and Perform the Future in a Virtual World: VR Applications to Assess and Enhance Episodic and Prospective Memory in Normal and Path…
2020
The process of aging commonly features a gradual deterioration in cognitive performance and, in particular, the decline of memory. Despite the increased longevity of the world's population, the prevalence of neurodegenerative conditions, such as dementia, continues to be a major burden on public health, and consequently, the latest research has been focused on memory and aging. Currently, the failure of episodic and Prospective memory (PM) is one of the main complaints in the elderly, considered among the early symptoms of dementia. It is therefore increasingly important to define more clearly the boundaries between normal and pathological aging. Recently, researchers have begun to build an…
New insigths relating to the beginning of the Neolithic in the eastern Spain: Evaluating empirical data and modelled predictions
2018
Abstract In this paper we present recent research concerning the neolithization process in the East of Spain, evaluating the time span between the last hunther-gatherer groups and the first farmers ( c . 5950–5150 cal. BC). To do that we have compiled and filtered current information about radiocarbon dates and sites in order to discuss the state of the art relating to the models used to explain the Neolithic spread in the region. In this sense we compare archaeological data with recent results of virtual model (ABM) in accordance with the scenarios and mechanisms proposed. On this basis we evaluate the empirical data relating to the current model for explaining the Neolithic spread at the …
EDU-SOCIAL ALGORITHM: A METHODOLOGICAL MODEL FOR USING SMARTPHONES AND INSTAGRAM IN GENERATION ALPHA’S EDUCATION THROUGH A COMMUNITY OF VIRTUAL PRACT…
2023
The Edu-social Algorithm research project aims to construct a micro-pedagogical, experimental, digital research action to create a methodological model using the functions and algorithms found in social media used by Generation Alpha (specifically Instagram). The project is the manifestation of an explorative research path seeking to alter the algorithms that form the basis of all the major platforms in current cyberspace, and in “Big Tech”. This alteration is possible through the development of a community of virtual practice, consisting of students and faculty working within Instagram through an interactive approach, to take pedagogical advantage of their mobile phones and apps. The quali…
Children’s Interactions Within a Virtual Reality Environment for Learning Chemistry
2017
This paper presents a virtual reality based solution for learning. Multimodal interactions are proposed to support students’ engagement through active experimentation and reflective observation. Students tasks are provided within an immersive virtual outdoor environment created using a human-centred design approach. Junior high school teachers and students between ages 14 and 16 were involved in design and test activities. Observations, video recordings, and interviews were used in data collection. Three interaction modalities were provided and tested: visual, auditory and kinesthetic/tangible interactions. The students involved in user testing showed great interest to learn in such an envi…
Adaptive Multi-agent System Based on Wasp-Like Behaviour for the Virtual Learning Game Sotirios
2018
The aim of this paper is to propose a model for an adaptive multi-agent system based on wasp-like behaviour for dynamic allocation of puzzles and quests in the virtual learning game SOTIRIOS. This is a digital learning game integrated inside a First Person Shooter designed by the second author of this paper. The learning process is based on many puzzles hidden in the game flow. The multi-agent system is necessary to integrate a multiplayer mode into the game. The agents use wasp task allocation behaviour, combined with a model of wasp dominance hierarchy in order to create a unique multiplayer learning system, where each user has a different learning curve, based on his results. The wasp be…
LabVIEW modeling and simulation, of the low-pass and high-pass analog filters
2015
Some programs for simulating different types of filters are developed using LabView software. Implementing a simulation program of an analog filter requires the prior establishment of mathematical model. As a general purpose programming environment, LabVIEW offers possibility of achieving some user programs for plotting frequency characteristics of passive and active analog filters, if established beforehand mathematical models that characterize their behavior. The scientific objectives of this paper are: -the analysis of the possibilities of using virtual instrumentation in the study of electrical filters; -implementation of virtual instruments for analysis and simulation of analog filters…
Modellazione e analisi tridimensionale dell'Agorà e della Basilica del sito archeologico di Elaiussa
2009
This paper describes the procedures used to generate 3D models of the Agora and the Byzantine Basilica of the Elaiussa archaeological site. The virtual reconstructions were carried out from the excavation data of the artefacts, made available by colleagues from the Department of Historical, Archaeological and Anthropological Science of Antiquities of the Rome “La Sapienza” University. 3D modelling software was particularly suitable to the reconstruction of these artefacts of which only few traces remain. In order to obtain a more accurate representation, 3D models of architectural elements of special value were also produced, as the capitals of the Agora re-employed in the Basilica and the …
Modelización computacional cardiaca
2020
Resumen Las enfermedades cardiovasculares tienen en la actualidad un gran impacto social y economico y constituyen una de las principales causas de mortalidad y morbilidad. Los modelos computacionales personalizados del corazon estan demostrando ser utiles tanto para ayudar a comprender los mecanismos subyacentes a las patologias cardiacas como para optimizar su tratamiento prediciendo la respuesta del paciente. En este contexto, se ha puesto en marcha la Red Espanola de Investigacion en Modelizacion Computacional Cardiaca (V-Heart SN). El objetivo general de V-Heart SN es el desarrollo de un modelo computacional multifisico y multiescala integrado del corazon. Este objetivo general se abor…
