Connectivity Analysis in EEG Data: A Tutorial Review of the State of the Art and Emerging Trends
2023
Understanding how different areas of the human brain communicate with each other is a crucial issue in neuroscience. The concepts of structural, functional and effective connectivity have been widely exploited to describe the human connectome, consisting of brain networks, their structural connections and functional interactions. Despite high-spatial-resolution imaging techniques such as functional magnetic resonance imaging (fMRI) being widely used to map this complex network of multiple interactions, electroencephalographic (EEG) recordings claim high temporal resolution and are thus perfectly suitable to describe either spatially distributed and temporally dynamic patterns of neural acti…
Kobieca strona dyskursu onkologicznego. Empiryczne spojrzenie na demokratyzację wiedzy medycznej
2015
Artykuł poprzez osadzanie w teoretycznych ramach konstruktywizmu wpisuje chorobę nowotworową piersi w kategorię dyskursu. Takie podejście wymaga zadania pytań o depozytariuszy wiedzy medycznej oraz jej źródła, formy i sposoby dystrybucji. Nie chodzi tu o negację istnienia określonych jednostek chorobowych, lecz raczej zwrócenie uwagi na złożone powiązania pomiędzy wiedzą medyczną a światem społecznym. Klarowny obraz obiektywnej wiedzy zaczyna tracić jednoznaczne kontury, gdy zestawi się alternatywne reprezentacje językowe w odmienny sposób porządkujące i interpretujące doświadczenia związane ze zdrowiem i chorobą. Na płaszczyźnie empirycznej analiza opiera się na wynikach badań ilościowych,…
Il contrasto all’odio e alla disinformazione in rete. Prime evidenze dalle campagne del progetto COMMIT
2023
Negli ultimi anni l’Europa ha dovuto affrontare le conseguenze di una crescente propaganda estremista, radicale e terroristica, che sempre più spesso trova spazio nei social media. Il contributo descrive il progetto COMMIT (COMMunIcation campaign against exTremism and radicalisation) che ha sviluppato, tra il 2020 e il 2022, una serie di attività di ricerca e di intervento con l’obiettivo, da un lato, di mappare il fenomeno della radicalizzazione online nei quattro Paesi partner (Italia, Grecia, Austria e Paesi Bassi) e individuare le caratteristiche dei gruppi più vulnerabili, dall’altro, di sviluppare le competenze di media literacy e di advocacy dei giovani destinatari del progetto.
Adaptive range-based localization algorithm based on trilateration and reference node selection for outdoor wireless sensor networks
2022
Locating the nodes of outdoor wireless sensor networks (WSNs) using (tri)lateration with a low-cost ranging technique, such as the received signal strength indicator (RSSI), often results in inaccurate location estimates. This can mostly be explained by the combined effect of distance estimate errors and localization geometry, both of which are subject to the reference nodes used. To develop techniques for reducing localization error, the distance estimate errors and localization geometry must be analyzed and taken into account. To address these challenges, this paper aims to seek ways to improve the quality of range-based trilateration localization for WSN nodes in varying outdoor conditio…
Wpływ mediatyzacji rytuałów na teatralizację współczesnej kultury
2018
Wykorzystywanie mediów w procesie komunikowania społecznego wpływa w coraz większym stopniu na przemiany tradycyjnej obrzędowości rodzinnej i dorocznej, a tym samym inspiruje powstawanie nowych sposobów realizowania w praktyce rytuałów (ceremonialnych zachowań) powiązanych z ważnym dla lokalnej grupy systemem wartości. Dawne rytuały, stopniowo tracąc swe powiązanie ze sferą sacrum, wypełniane są nowymi treściami i podlegają procesowi teatralizacji, przy znaczącym udziale mediów. Autorka prezentuje to na przykładzie obrzędu weselnego i dorocznych tradycyjnych zwyczajów karnawałowych. Postępująca mediatyzacja komunikacji inspiruje też przemieszczanie się rytuałów do nowych przestrzeni kulturo…
Inclusive Decision-making and Campaign: The Participation of Second Generation Migrants for Preventing Radicalization
2019
This paper deals with the analysis of the first results of Oltre project (ISF - DG Migration and Home Affairs, EU) funding for preventing the radicalization of the second-generation of migrants. The non-standard field research was intertwined with online social network profiles investigation. We present the off-line research results. Starting from the different dimensions of the risk of radicalization proposed by the kaleidoscopic overview of risk factors (Sieckelinck and Gielen 2018: 5; Ranstorp 2016), we created a topic guide for the indepth qualitative interviews collecting 42 interviews of 2G youths (18-30 years) in 7 Italian towns, interviewing also several privileged testimonies. Then…
Entry and processing of Borrelia burgdorferi pleomorphic forms
2015
Lymen borrelioosi on Suomessakin yleinen puutiaisten levittämä tauti. Borrelioosin ensimmäisiä oireita ovat muun muassa puutiaisen pureman ympärille muodostuva ihottuma, päänsärky, väsymys ja kuume. Myöhemmin tauti voi aiheuttaa nivel- tai sydäntulehduksen sekä neurologisia oireita. Borrelioosi on monessa suhteessa kiistanalainen tauti, sillä esimerkiksi sen hoidosta ja mahdollisesta kroonistumisesta on kaksi eriävää näkemystä. Taudin aiheuttaja on Borrelia burgdorferi -bakteeri (Bb). Bb pystyy välttelemään isännän immuunipuolustusta useilla eri mekanismeilla. Bakteeri on korkkiruuvinmuotoinen spirokeetta, mutta voi esiintyä myös epätyypillisinä muotoina, joihin kuuluu esimerkiksi pyöreä mu…
Measuring the Task Induced Oscillatory Brain Activity Using Tensor Decomposition
2019
The characterization of dynamic electrophysiological brain activity, which form and dissolve in order to support ongoing cognitive function, is one of the most important goals in neuroscience. Here, we introduce a method with tensor decomposition for measuring the task-induced oscillations in the human brain using electroencephalography (EEG). The time frequency representation of source-reconstructed singletrail EEG data constructed a third-order tensor with three factors of time ∗ trails, frequency and source points. We then used a non-negative Canonical Polyadic decomposition (NCPD) to identify the temporal, spectral and spatial changes in electrophysiological brain activity. We validate …
Joint Subcarrier and Phase Shifts Optimization for RIS-aided Localization-Communication System
2022
Joint localization and communication systems have drawn significant attention due to their high resource utilization. In this paper, we consider a reconfigurable intelligent surface (RIS)-aided simultaneously localization and communication system. We first determine the sum squared position error bound (SPEB) as the localization accuracy metric for the presented localization-communication system. Then, a joint RIS discrete phase shifts design and subcarrier assignment problem is formulated to minimize the SPEB while guaranteeing each user’s achievable data rate requirement. For the presented non-convex mixed-integer problem, we propose an iterative algorithm to obtain a suboptimal solution …
Sense experience and differentiation : Husserl on bodily awareness
2023
This article outlines the basic ingredients of Husserl’s theory of bodily awareness. It first analyses the concepts of hyletic and kinesthetic sensibility, and illustrates the interwovenness and equiprimordiality of Me and not-Me in Husserl’s account. Second, it shows how the concept of the lived body emerges from this complex sensible foundation. Thirdly, it argues that, as the area of intersection between the Me and the not-Me, bodily awareness is the initial locus of differentiation between Me and not-Me: an area where the experiential distinction between the Me and the not-Me is constantly negotiated. peerReviewed
