Mind-wandering and mindfulness as mediators of the relationship between online vigilance and well-being
2018
Contains fulltext : 199030pub.pdf (Publisher’s version ) (Closed access) As mobile technology allows users to be online anywhere and at all times, a growing number of users report feeling constantly alert and preoccupied with online streams of online information and communication - a phenomenon that has recently been termed online vigilance. Despite its growing prevalence, consequences of this constant orientation toward online streams of information and communication for users' well-being are largely unclear. In the present study, we investigated whether being constantly vigilant is related to cognitive consequences in the form of increased mind-wandering and decreased mindfulness and exam…
State of the Art Literature Review on Network Anomaly Detection
2018
As network attacks are evolving along with extreme growth in the amount of data that is present in networks, there is a significant need for faster and more effective anomaly detection methods. Even though current systems perform well when identifying known attacks, previously unknown attacks are still difficult to identify under occurrence. To emphasize, attacks that might have more than one ongoing attack vectors in one network at the same time, or also known as APT (Advanced Persistent Threat) attack, may be hardly notable since it masquerades itself as legitimate traffic. Furthermore, with the help of hiding functionality, this type of attack can even hide in a network for years. Additi…
Affective (re)orientations in online discussions on the threat of violence posed by migrants
2020
Online discussions are rife with fear-evoking images and meaning making that highlight a perceived threat to the security of European nations and their inhabitants posed by migrants’ violence in the wake of increased immigration. This paper examines the role of emotions in shaping anti-immigration views as a response to the threat of violence attached to migrants in online conversations. Using a dataset of Finnish online discussion threads from 2015 to 2017 that were prompted by extensive media attention paid to various cases of violent crime in which migrants were suspects, we particularly analyse the affective dynamics of interpellation processes wherein discussants are invited to adopt a…
The popularization of plate tectonics: presenting the concepts of dynamics and time
1996
There have been many attempts to describe and represent the theory of plate tectonics to laypeople. In the context of a study conducted at the request of a museum, we have tried to determine how the concepts of both geological time and the movements of the plates have been reformulated. After having systematically studied in detail publications aimed at more or less educated readers, we have selected a corpus of twelve articles from nine different magazines or journals. Among the different means of expression used by the popularizers, rhetorical figures constitute a significant resource. Procedures based on analogy (metaphor, comparison, analogical reasoning) were brought together in a sing…
From the prehistoric to the posthuman selfie
2019
Abstract LeRoy McDermott’s hypothesis proposes a perceptual interpretation of the Venus statues from to the Upper Paleolithic period these being in fact the first examples of human self-representations. The arguments he brings are of an artistic nature par excellence and they refer to the visual distortions arising from the subject’s point of view. The fantasy of being admired by others through the means of the nude selfie has generated a whole trend in today’s pop culture and Kim Kardashian is a prime example in this sense. The “shareware body” has gone through an entire history of significance, from Albrecht Dürer’s mystical meaning of the body, to Érika Ordosgoitti’s activist take on the…
A future of journalism beyond the objectivity-dialogue divide? : Hybridity in the news of entrepreneurial journalists
2019
As pioneers of new ideas and practices, many entrepreneurial journalists spearhead the change of journalism towards hybridity. By applying appraisal theory, this article examines a hybrid of objectivity and dialogue in daily news articles by five entrepreneurial journalism outlets – Axios, MustRead, National Observer, The Skimm and the Voice of San Diego. For comparative purposes, a dataset from three legacy media outlets was also analysed. The results show that the entrepreneurial journalism outlets employ journalistic dialogue in otherwise stylistically objective news texts notably more often than do legacy media outlets. Dialogic registers provide subtle, non-partisan assessments of eve…
Digital Home: Life Transitions and Digital Domestic Practices in Later Life
2019
As older adults become active users of digital technologies, digital activity among this age group is increasingly associated with life stage factors. This paper discusses the understanding of life stage as explanatory factors in older adults’ digital engagement by exploring the association between life transitions and digital domestic practices in Finland. The study is based on an analysis of qualitative, in-person interview data from 20 participants between the ages of 50 and 78 who recently bought their own apartment in Western or Central Finland. The aims are to identify variances of life transitions in relation to domestic practices, investigate the association between life transitions…
Las competencias básicas en la nueva generación de estudiantes universitarios: Una experiencia de Innovación.
2017
[EN] This contribution presents an innovative teaching experience dedicated to developing core competencies in the university student by activating educational practices and evaluation procedures that seek to promote and maximize various competitions. This experiencie has been implemented in different degrees of the University of Valencia during the academic years 2011-12, 2012-13, 2013-14 and 2014-15. Participating in the study 1285 students through accidental sampling accessibility. After developing a survey methodology based on descriptive-exploratory analyzes data collected allow us to know what is the degree of control perceived by university students around the following core competen…
Error-Based Interference Detection in WiFi Networks
2017
In this paper we show that inter-technology interference can be recognized by commodity WiFi devices by monitoring the statistics of receiver errors. Indeed, while for WiFi standard frames the error probability varies during the frame reception in different frame fields (PHY, MAC headers, payloads) protected with heterogeneous coding, errors may appear randomly at any point during the time the demodulator is trying to receive an exogenous interfering signal. We thus detect and identify cross-technology interference on off-the-shelf WiFi cards by monitoring the sequence of receiver errors (bad PLCP, bad PCS, invalid headers, etc.) and develop an Artificial Neural Network (ANN) to recognize t…
Preamble Transmission Prediction for mMTC Bursty Traffic : A Machine Learning based Approach
2020
The evolution of Internet of things (IoT) towards massive IoT in recent years has stimulated a surge of traffic volume among which a huge amount of traffic is generated in the form of massive machine type communications. Consequently, existing network infrastructure is facing challenges when handling rapidly growing traffic load, especially under bursty traffic conditions which may more often lead to congestion. By proactively predicting the occurrence of congestion, we can implement necessary means and conceivably avoid congestion. In this paper, we propose a machine learning (ML) based model for predicting successful preamble transmissions at a base station and subsequently forecasting th…
