Does Car Sharing Contribute to Urban Sustainability from User-Motivation Perspectives?

2021

Mobility, its current state and development perspectives in the future creates challenges with respect to sustainability, the first of which is the uncontrolled increase in greenhouse gas emissions in the last few decades, while road transport is one of the “sinners” creating long-term negative impact. The second is the dominance of car travel and car usage in the passenger transportation segment before the latest COVID-19 pandemic accelerated environmental problems. Although recent trends show new, greener patterns in consumption, there is still a relatively low share of consumers acknowledging the importance of sustainable and green preferences. This research study aims to investigate car…

The ethos of conviviality. From the table to the tablet

2012

Manifestée d’abord dans l’espace physique et symbolique de la table et associée au plaisir de partager de bons mets, la convivialité se déplace aujourd’hui dans de multiples espaces de la vie sociale : les relations quotidiennes, les conditions de travail, le rapport aux objets. À cet égard la convivialité prend une place tout à fait significative dans les usages des interfaces numériques. Ainsi s’opère le glissement sémiotique et pragmatique de la convivialité, de la table à la tablette, avec le maintien de propriétés substantielles de cette valeur de confiance et de bien-être et des conversions figuratives de sa manifestation dans de nouveaux espaces. C’est le cas, notamment, de la gare c…

Are Online Haters Psychopaths? Psychological Predictors of Online Hating Behavior

2020

Despite growing prevalence of derogatory online behaviors, still little is known about psychological factors underlying this negative phenomenon. In the present study, we aimed to compare characteristics of persons who post hating and non-hating comments about Polish sports players during Winter Olympic Games in Pyeongchang (2018) on the Internet. Ninety-four Internet users (41% women) participated in the study, among which 46 posted hating comments. After one month, participants were invited to take part in a psychological survey, and filled the Dark Triad questionnaire, the Satisfaction with Life Scale, the Scale of Frustration, and the Scale of Envy. Results showed that high scores in Ps…

GPCALMA: An Italian mammographic database of digitized images for research

2006

In this work the implementation of a database of digitized mammograms is described. The digitized images were collected since 1999 by a community of physicists in collaboration with radiologists in several Italian hospitals, as a first step in order to develop and implement a Computer Aided Detection (CAD) system. 3369 mammograms were collected from 967 patients; they were classified according to the type and the morphology of the lesions, the type of the breast tissue and the type of pathologies. A dedicated Graphical User Interface was developed for mammography visualization and processing, in order to support the medical diagnosis directly on a high-resolution screen. The database has be…

2019

Background Health apps for the screening and diagnosis of mental disorders have emerged in recent years on various levels (eg, patients, practitioners, and public health system). However, the diagnostic quality of these apps has not been (sufficiently) tested so far. Objective The objective of this pilot study was to investigate the diagnostic quality of a health app for a broad spectrum of mental disorders and its dependency on expert knowledge. Methods Two psychotherapists, two psychology students, and two laypersons each read 20 case vignettes with a broad spectrum of mental disorders. They used a health app (Ada—Your Health Guide) to get a diagnosis by entering the symptoms. Interrater…

Endoscopic management of a case of 'complete septate uterus with unilateral haematometra'

1995

Endoscopy and ultrasound was used to diagnose a 13 year old virgin girl who presented with dysmenorrhoea and suspected right side adnexal tumescence. The girl was found to have a complete septate uterus with non-communicating right hemicavity and haematometra, an exceptional type of Mullerian anomaly. After pretreatment with buserelin, hysteroscopic metroplasty was successfully performed.

3D reconstruction techniques made easy: know-how and pictures

2005

Three-dimensional reconstructions represent a visual-based tool for illustrating the basis of three-dimensional post-processing such as interpolation, ray-casting, segmentation, percentage classification, gradient calculation, shading and illumination. The knowledge of the optimal scanning and reconstruction parameters facilitates the use of three-dimensional reconstruction techniques in clinical practise. The aim of this article is to explain the principles of multidimensional image processing in a pictorial way and the advantages and limitations of the different possibilities of 3D visualisation.

Role of virtopsy in the post-mortem diagnosis of drowning.

2014

Purpose: Due to admitted limits of autopsy-based studies in the diagnosis of drowning, virtopsy is considered the new imaging horizon in these post-mortem studies. The aim of our study was to evaluate the role of virtopsy performed through computed tomography (CT) in the forensic diagnosis of drowning. Materials and methods: We retrospectively examined the CT data of four cadavers recovered from sea water and suspected to have died by drowning. Each patient underwent a full-body post-mortem CT scan, and then a traditional autopsy. Conclusion: To date, there are no autopsy findings pathognomonic of drowning. This study proves that virtopsy is a useful tool in the diagnosis of drowning in tha…

Web Personalization : The State of the Art and Future Avenues for Research and Practice

2016

Provide a review of current developments in web personalization.Show evolution toward more complex contextualized approaches.Identify research gaps in web personalization and in six specific research streams.Propose web personalization to be complemented with interpolated approaches. Although web personalization has been examined by earlier literature reviews, an updated analysis of recent advances in the field is needed. The authors extend prior reviews of web personalization by discussing current areas of interest, research gaps and future directions.

Dynamic, Behavior-Based User Profiling Using Semantic Web Technologies in a Big Data Context

2013

pp. 363-372; International audience; The success of shaping the e-society is crucially dependent on how well technology adapts to the needs of each single user. A thorough understanding of one's personality, interests, and social connections facilitate the integration of ICT solutions into one's everyday life. The MindMinings project aims to build an advanced user profile, based on the automatic processing of a user's navigation traces on the Web. Given the various needs underpinned by our goal (e.g. integration of heterogeneous sources and automatic content extraction), we have selected Semantic Web technologies for their capacity to deliver machine-processable information. Indeed, we have…
