Early root surface colonization by human periodontal ligament fibroblasts following treatment with different biomaterials
2013
The present in-vitro study examined the effects of different biomaterials on early root surface colonization by human periodontal ligament (PDL) fibroblasts using confocal-laser-scanning-microscopy (CLSM).Fifteen periodontally-diseased teeth were extracted, treated with scaling/root planing and longitudinally cut to obtain 30 root fragments. Fragments were treated either with 24% EDTA following application of enamel matrix derivative (EMD), 24% EDTA or EMD only, nanocrystalline hydroxyapatite (NHA) paste or oily calcium hydroxide suspension (OCHS) for 1 h each. The analogue untreated root specimens served as controls. Root fragments were incubated with human PDL fibroblasts and cellular pro…
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…
Matt Kish’s “Every Page of Moby-Dick, Illustrated”: A Multimodal Approach
2016
Abstract The purpose of this essay is to address the multimodal nature of Matt Kish’s project Every Page of Moby-Dick, Illustrated, where Herman Melville’s 1851 masterpiece is set as paratext. Particular focus is set on the portrayals of Captain Achab, specifically “Page 153”, “Page 465” and “Page 469”. The basic theoretical framework has been offered by Alice Gibbons’ theorization of multimodal cognitive poetics and Sigrid Norris’ systematization of multimodal (inter)action. Useful insight has been lent by Sharon Cameron’s work on allegories of the body in Melville’s writing. The given analysis aims to pinpoint the elements of innovation in Kish’s work with respect to the canonical formal …
Geometric Calculus Applications to Medical Imaging: Status and Perspectives
2021
Medical imaging data coming from different acquisition modalities requires automatic tools to extract useful information and support clinicians in the formulation of accurate diagnoses. Geometric Calculus (GC) offers a powerful mathematical and computational model for the development of effective medical imaging algorithms. The practical use of GC-based methods in medical imaging requires fast and efficient implementations to meet real-time processing constraints as well as accuracy and robustness requirements. The purpose of this article is to present the state of the art of the GC-based techniques for medical image analysis and processing. The use of GC-based paradigms in Radiomics and De…
Museums as Disseminators of Niche Knowledge
2019
Accessibility has been facing several challenges within Audiovisual Translation Studies and has also gained great opportunities for its establishment as a methodologically and theoretically well-founded discipline. Audiovisual translation modes have achieved a crucial role in the transmission of what scholarly studies have discussed in relation to media accessibility as a set of services and practices providing access to audiovisual media content for persons with sensory impairment. Today accessibility has become a concept involving more and more universality, since it is extensively contributing to the dissemination of audiovisual and visual products about issues on minorities, and also ad…
Implementing Intellectual Property Policies in a Romanian State University
2018
The paper presents a series of contributions on the possibility of implementing intellectual property policies in a Romanian State University. Starting with the worldwide, well-known examples of universities with a tradition in this field of intellectual property protection, the paper presents practical solutions for the implementation of some intellectual property policies taking into account the mentality which currently exists in Romania on this subject. The study is based on the important experience gained by authors in a European research project involving 15 partners from 9 countries, where the results were remarkable. The University must represent a pole of excellence in research, bu…
Aging effects and feasibility of statistical learning tasks across modalities
2021
Knowledge on statistical learning (SL) in healthy elderly is scarce. Theoretically, it is not clear whether aging affects modality-specific and/or domain-general learning mechanisms. Practically, there is a lack of research on simplified SL tasks, which would ease the burden of testing in clinical populations. Against this background, we conducted two experiments across three modalities (auditory, visual and visuomotor) in a total of 93 younger and older adults. In Experiment 1, SL was induced in all modalities. Aging effects appeared in the tasks relying on an explicit posttest to assess SL. We hypothesize that declines in domain-general processes that predominantly modulate explicit learn…
Architecture to Serve Disabled and Elderly
2013
We propose an architecture (discussed in the context of a dressing and cleaning application for impaired and elderly persons) that combines a cognitive framework that generates motor commands with the MOSAIC architecture which selects the right motor command according to the proper context. The ambition is to have robots able to understand humans intentions (dressing or cleaning intentions), to learn new tasks only by observing humans, and to represent the world around it by using conceptual spaces. The cognitive framework implements the learning by demonstration paradigm and solves the related problem to map the observed movement into the robot motor system. Such framework is assumed to wo…
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…
Changing commuters’ mobility behaviors of university campuses: environmental and energy comparisons
2021
Governments are required to take proper measures to promote the use of electric and hybrid vehicles and, more generally, to push people towards sweeter modalities including walking and biking. To reach such tight and challenging goals, local institutions should be deeply involved, and universities among them. The promotion of sustainable mobility practices among commuter students must be considered indeed an effective contribution to facilitating the transition towards greener cities. On purpose, students of the University of Palermo that daily commute from their residences to the campus are considered here. These commuters, in fact, mainly adopt traditional polluting transportation means. …
