Robotization of Mobile Communication

2020

The aim of this chapter is to systematize the discussion regarding robotization of mobile communication. The chapter begins by clarifying the fundamental role of both robot hardware and robot software in this process. This is followed by a critical overview of existing research, which is classified into three categories. First, robotization is understood as the hybridization of the human body with existing ordinary mobile devices. Second, the incorporation of new robotic software, such as algorithms, artificial intelligence, and virtual assistants, into mobile devices is seen to robotize them from inside. Third, the convergence of smart communication devices, typically as user interfaces wi…

Monitoring a meat-free pledge with smartphones:An experimental study

2020

Pledges are a popular strategy to encourage meat reduction, though experimental studies of their efficacy are lacking. Three-hundred and twenty-five participants from three different countries (UK, Germany, Australia) were randomly assigned to pledge 28 days meat-free or not, and their behavior was tracked via smartphones. Participants answered daily surveys regarding their eating behavior, meat cravings, and shared photos of their meals. Baseline data was collected prior to the pledge, after the 28 days, and one-month post-intervention. Participants assigned to the pledge condition ate less meat across the 28 days, compared to control participants. Meat reductions, observed at outtake, did…

Overbooked: the exploding business of travel & tourism

Displacing to uncertain landscapes sets us free but at the same time, it poses a series of concerns. The given context of adventure and open destiny leads us to document our experiences to be read ...

Exegesis and myths as methodologies of research in tourism

2013

Anthropology has given interesting paradigms to tourism-led research. From the role played by culture to the conflict between host and guest, anthropology has focused in mobility and tourism issues. Nonetheless, when we think in tourism we imagine an all-encompassing institution. There were many forms of tourism, each one enrooted in their own culture. Mythology and exegesis remind not only that other non-western forms of tourism are interesting to study but also how we can examine those cultural values that do not exist any longer. What this note of research sustains is that positivism monopolized in tourism fields some methods at the time pushing others to the periphery of knowledge, like…

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…

Data from: Behavioural responses of Atlantic cod to sea temperature changes

2016

Understanding responses of marine species to temperature variability is essential to predict impacts of future climate change in the oceans. Most ectotherms are expected to adjust their behavior to avoid extreme temperatures and minimize acute changes in body temperature. However, measuring such behavioral plasticity in the wild is challenging. Combining 4 years of telemetry-derived behavioral data on juvenile and adult (30–80 cm) Atlantic cod (Gadus morhua), and in situ ocean temperature measurements, we found a significant effect of sea temperature on cod depth use and activity level in coastal Skagerrak. During summer, cod were found in deeper waters when sea surface temperature increase…

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…

Digital Acquisition and Processing of Video Angiocardiograms

1986

Angiocardiographic diagnosis is still mainly based on the visual assessment of radiographic projection images recorded on photographic film. Considerable amounts of contrast material have to be selectively injected into the circulation in order to make the regions of diagnostic relevance visible in the superposition of the shadows of tissue and bone structures displayed in these transmission images. In addition, selective angiocardiography requires exact positioning of the catheter, a time-consuming procedure which is not without risk. The processing of the angiographie films obtained is difficult to maintain at a constant high quality level, and this introduces an disadvantageous delay bet…

Mesoporous Silica-Based Materials with Bactericidal Properties

2019

[EN] Bacterial infections are the main cause of chronic infections and even mortality. In fact, due to extensive use of antibiotics and, then, emergence of antibiotic resistance, treatment of such infections by conventional antibiotics has become a major concern worldwide. One of the promising strategies to treat infection diseases is the use of nanomaterials. Among them, mesoporous silica materials (MSMs) have attracted burgeoning attention due to high surface area, tunable pore/particle size, and easy surface functionalization. This review discusses how one can exploit capacities of MSMs to design and fabricate multifunctional/controllable drug delivery systems (DDSs) to combat bacterial …
