Social representations of COVID-19 (Representaciones sociales del COVID-19)
2020
This is a reflection on the communication modalities of dissemination, propagation and propaganda as they have manifested in the COVID-19 pandemic. It describes the anchoring of the representations...
Accentuating the Interrelation between Consumer Intention and Healthy Packaged Food Selection during COVID-19: A Case Study of Pakistan
2021
This study contemplates the factors that influence consumer intention, before and during the eruption of COVID-19, for the selection of healthy packaged food in Pakistan. The extant studies have identified two distinct attitudes of consumers about food label information: one is its usefulness and the second elucidates the avoidance. Hence forth, the current study contributes to the extant literature while signifying both reasons which motivate consumers to read food labels and reasons which discourage consumers from consult food labels at the point of purchase. Moreover, the impact of subjective norms and self-efficacy for healthy packaged food intentions has also been examined for both bef…
Computing the Original eBWT Faster, Simpler, and with Less Memory
2021
Mantaci et al. [TCS 2007] defined the \(\mathrm {eBWT}\) to extend the definition of the \(\mathrm {BWT}\) to a collection of strings. However, since this introduction, it has been used more generally to describe any \(\mathrm {BWT}\) of a collection of strings, and the fundamental property of the original definition (i.e., the independence from the input order) is frequently disregarded. In this paper, we propose a simple linear-time algorithm for the construction of the original \(\mathrm {eBWT}\), which does not require the preprocessing of Bannai et al. [CPM 2021]. As a byproduct, we obtain the first linear-time algorithm for computing the \(\mathrm {BWT}\) of a single string that uses …
P463 COVID-19 vaccination willingness and hesitancy in patients with Inflammatory Bowel Diseases (IBD): analysis of determinants in a national survey…
2021
Abstract Background Vaccine hesitancy, the delay in acceptance or refusal of vaccination despite its availability, represents a threat to the diffusion and lethality of infectious diseases. COVID-19 vaccination has been recommended by national and international organizations in patients with Inflammatory Bowel Diseases (IBD). The aim of the study was to evaluate COVID-19 vaccine willingness and hesitancy in a population of Italian patients with IBD, and their determinants. Methods In February 2021 an online questionnaire focused on COVID-19 vaccine was proposed to a representative sample of Italian IBD patients. Socio-demographic characteristics, IBD features, lifestyle, perception of COVID…
Mapping the Idea of Europe : Cultural Production of Border Imaginaries through Heritage
2021
In contrast to recent reinforcements of Europe's internal and external borders due to the refugee situation on the Mediterranean and the Covid-19 outbreak, talk of European borders has in the past decades focused on the freedom of mobility guaranteed by the Schengen treaty. In many senses, free intra-European mobility has become a recited truth in the EU discourse: a phrase that hides under its repetition the gap between its implied content and empirical realities of many of those who are affected by European borders’ exclusive tendencies. Through the concept of borderscape, this article focuses on the role that cultural products – especially maps exhibited at heritage sites – have in recit…
Meta-analysis of real-time fMRI neurofeedback studies using individual participant data: How is brain regulation mediated?
2015
An increasing number of studies using real-time fMRI neurofeedback have demonstrated that successful regulation of neural activity is possible in various brain regions. Since these studies focused on the regulated region(s), little is known about the target-independent mechanisms associated with neurofeedback-guided control of brain activation, i.e. the regulating network. While the specificity of the activation during self-regulation is an important factor, no study has effectively determined the network involved in self-regulation in general. In an effort to detect regions that are responsible for the act of brain regulation, we performed a post-hoc analysis of data involving different ta…
The Catalunya Conundrum, Part 2: A Full-Blown Constitutional Crisis for Spain
2017
In Part 1, we have explained the rigidity of the constitutional doctrine of our Constitutional Court on the matter of regional independence movements. There are some evident conclusions that swiftly appear – most of all that the only legal way for a hypothetical majority of Catalan citizens to express their wish to secede or at least to consult with the population on the issue, would presuppose a constitutional reform. This is a tremendously complicated matter in itself, though.
SfM Techniques Applied in Bad Lighting and Reflection Conditions: The Case of a Museum Artwork
2019
In recent years, SfM techniques have been widely used especially in the field of Cultural Heritage. Some applications, however, remain undefined in cases where the boundary conditions are not suitable for the technique. Examples of this are instances where there are poor lighting conditions and the presence of glass and reflective surfaces. This paper presents a case study where SfM is applied, using a DSLR camera (Nikon D5200), to the “Head of Hades” inside a glass theca and under a large number of light sources at different distances and of different intensities and sizes. The geometric evaluation has been made comparing the DSLR camera model against the 3D data acquired with structured l…
A simulation model for wideband MIMO vehicle-to-vehicle fading channels in T-junction propagation environments
2010
In this paper, we propose a high-performance simulation model for wideband multiple-input multiple-output (MIMO) vehicle-to-vehicle (V2V) fading channels in T-junction propagation environments. The so-called Riemann sum method (RSM) is applied for the parametrisation of the simulation model. Furthermore, the statistical properties of the wideband MIMO V2V channel simulation model, such as the space-time-frequency cross-correlation function (STF-CCF), the two-dimensional spatial cross-correlation function (2D spatial CCF) and the temporal auto-correlation function (ACF) are studied. Finally, the high accuracy of the proposed simulation model is demonstrated by comparing the correlation prope…
ATR-Spin: an open-source 3D printed device for direct cytocentrifugation onto attenuated total reflectance crystals.
2021
Infrared Spectroscopy (IR) enables the direct and rapid characterization of cells at the molecular level. Achieving a rapid and consistent cell preparation is critical for the development of Point-of-Care diagnostics for cell analysis. Here we introduce an open-source, 3D printed device for integrating the isolation, preconcentration, and measurement of attenuated total reflectance IR spectra of cells from biofluids. The tool comprises a disposable card for cytocentrifugation, equipped with magnets, which allows reproducible integration into the pathlength of the IR spectrophotometer. Preliminary results using cell media containing A459 cells indicate that this system enables a qualitative …
