Modified total variation regularization using fuzzy complement for image denoising

2015

In this paper, we propose a denoising algorithm based on the Total Variation (TV) model. Specifically, we associate to the regularization term of the Rodin-Osher-Fatimi (ROF) functional a small weight whenever denoising is performed in edge and texture regions, which means less regularization and more details preservation. On the other hand, a large weight is associated if the region being filtered is smooth which means noise will be well suppressed. The weight computation is inspired from the fuzzy edge complement. Experiments on well-known images and comparison with state of the art denoising algorithms demonstrate that the proposed method not only presents good denoising performance but …

Premorbid Personality Traits as Risk Factors for Behavioral Addictions: A Systematic Review of a Vulnerability Hypothesis

2023

The debate on personality structure and behavioral addictions is an outstanding issue. According to some authors, behavioral addictions could arise from a premorbid personality, while for others, it could result from a pathological use of technological tools. The current study aims to investigate whether, in the latest literature, personality traits have been identified as predictors of behavioral addictions. A literature search was conducted under the PRISMA methodology, considering the most relevant studies of the five-factor model from the past 10 years. Overall, most studies on addiction, personality traits, and personality genetics proved that behavioral addiction may be an epiphenomen…

The Association Between Video Gaming and Psychological Functioning

2019

Video gaming is an extremely popular leisure-time activity with more than two billion users worldwide (Newzoo, 2017). However, the media as well as professionals have underscored the potential dangers of excessive video gaming. With the present research, we aimed to shed light on the relation between video gaming and gamers’ psychological functioning. Questionnaires on personality and psychological health as well as video gaming habits were administered to 2,734 individuals (2,377 male, 357 female, Mage = 23.06, SDage = 5.91). Results revealed a medium-sized negative correlation between problematic video gaming and psychological functioning with regard to psychological symptoms, affectivity…

Success factors of game industry crowdfunding campaigns

2017

Tutkimuksen tarkoituksena oli selvittää mitkä ovat pelialan joukkorahoituskampanjoiden menestystekijöitä. Aiempaan joukkorahoitukseen sekä pelialaan keskittyneiden tutkimusten perusteella luotiin teoreettinen malli kuvaamaan tärkeimpiä menestystekijöitä ja niiden suhteita. Tätä mallia testattiin haastattelemalla kolmen eri joukkorahoituskampanjan perustajia. Aiemman teorian sekä haastattelujen perusteella selvisi, että pelialan joukkorahoituskampanjoilla on kuusi selkeää menestystekijää: kampanjan palkkiot, kampanjan tavoitteet, kampanjan sekä tuotteen laatu, projektitiimi, joukkorahoittajien luoma yhteisö sekä suoritetut esivalmistelut. Tutkimustuloksia ja niiden perus…

Risk and protective factors for (internet) gaming disorder: A meta-analysis of pre-COVID studies.

2023

This large-scale meta-analysis aimed to provide the most comprehensive synthesis to date of the available evidence from the pre-COVID period on risk and protective factors for (internet) gaming disorder (as defined in the DSM-5 or ICD-11) across all studied populations. The risk/protective factors included demographic characteristics, psychological, psychopathological, social, and gaming-related factors. In total, we have included 1586 effects from 253 different studies, summarizing data from 210557 participants. Apart from estimating these predictive associations and relevant moderating effects, we implemented state-of-the-art adjustments for publication bias, psychometric artifacts, and o…

Machine Translation and Gender biases in video game localisation: a corpus-based analysis

2021

The video game industry has been a historically gender-biased terrain due to a higher number of male protagonists and hypersexualised representations [Dietz, 1998; Downs & Smith, 2010; Lynch et al., 2016]. Nowadays, echoing the debate on inclusive language, companies attempt to erase gender disparity by introducing main female characters as well as non-binary characters. From a technological point of view, even though recent studies show that Machine Translation remains largely unadopted by individual video game localisers [Rivas Ginel, 2021], multilanguage vendors are willing to invest in these tools to reduce costs [LIND, 2020]. However, the predominance of the masculine in Natural La…

Video display terminal use and dry eye: preventive measures and future perspectives

2022

Background: Dry eye disease (DED) is a common cause of ocular pain and discomfort. Dry eye disease (DED) stems from a loss-of-tear film homeostasis and is frequently seen in video display terminal (VDT) users. Video display terminal (VDT) use reduces blink rates and increases incomplete blinks, leading to tear film instability and ocular inflammation, promoting DED. Purpose: To assess and evaluate the methods for preventing VDT-associated DED and ocular discomfort. Methods: Studies were found using PubMed and Embase with the search terms: (digital visual terminal* OR computer use OR screen use OR smartphone OR display OR visual display terminal* OR computer vision syndrome OR tablet OR phon…

YouTube ja videot: arkea, huumoria vai asiaa?

2017

YouTube mielletään usein tavallisten ihmisten tekemien videoiden aarreaitaksi. Nuoret tubettajat ovat suosittuja videoiden sisällöntuottajia kertoessaan videoissa omista arkisista kokemuksistaan ja muista elämänpiiriinsä liittyvistä tapahtumista. Todellisuudessa YouTuben videot eivät kuitenkaan ole yhtenäinen lajityyppi, ja usein videot olla ammattimaisesti tuotettuja. Videot edellyttävät vaativat medialukutaitoa, joka auttaa tunnistamaan niiden kielelliset ja visuaaliset tavat ilmaista asioita. Videoita löytyy monilla eri kielillä ja monista aiheista ja kiinnostuksen kohteista. Kielenopiskelun kannalta ne tarjoavat ehtymättömän lähteen autenttista materiaalia. nonPeerReviewed

“You really brought all your feelings out” : Scaffolding students to identify the socio-emotional and socio-cognitive challenges in collaborative lea…

2021

The aim of this study is to explore how students experience and describe socio-cognitive and socio-emotional challenges in collaborative learning. The participants (N = 20) were teacher education students whose collaborative learning was supported with a designed regulation macro script during a six-week mathematics course. The purpose of the script was to provide structured phases during the collaborative learning tasks for the group members to plan, monitor, and evaluate their workings. The video data of groups' face-to-face work was collected and analysed by focusing on the different types of challenges the groups experienced and the types of challenges they described during the scripted…
