Innovators and innovated: Newspapers and the postdigital future beyond the “death of print”
2017
Along with other cultural organizations, newspapers, through waves of digital disruption, have become subject to a dominant narrative of crisis. But newspapers have long participated in change. A constructivist approach, qualified by consideration of media materiality, draws attention to diverse but essential processes of innovation around them. We see a contraflow of migration from digital to print, opening up a shared media space; bonding strategies are bringing multimedia to ink on paper, while bridging via boundary objects such as QR (Quick Response) codes are connecting the two. Among other initiatives, development of automation of news production and experiments with transparency are …
Teachers’ Work-Related Well-Being in Times of COVID-19: The Effects of Technostress and Online Teaching
2022
Following the outbreak of the COVID-19 pandemic, one of the first measures implemented in Italy was the transition from frontal teaching to online teaching. The sudden need to use technologies to perform their job has added a source of stress to teachers’ work: so-called technostress. The difficulties experienced in this transition may also have affected the perception of work-related well-being, although other variables, such as the perception of the meaningfulness of work, could alleviate this sense of uneasiness. The study aims to examine the relationships between technostress, online teaching, pleasure in working, and meaningful work perceptions among 219 teachers from different school …
Metáforas visuales en los mundos virtuales. El caso de NANEC 2010/11
2011
Antes de la invención de la imprenta la narración oral de historias era la gran transmisora del conocimiento. La imprenta otorgó velocidad y perennidad a la narración, ampliando el tiempo para su reflexión. Con Internet se fragmenta la secuencialidad del mensaje y es posible crear nuevas realidades que pueden tener o no su referente en el mundo real. Los mundos virtuales son un claro ejemplo de ello.
Cognitive-behavioral treatment of online role-playing videogames: proposal of treatment and a case study
2014
El propósito de este trabajo es presentar una propuesta de tratamiento cognitivo-conductual para la intervención en la adicción a video juegos. Se presenta el caso de un varón de 21 años con problemas con el uso de los videojuegos. Se expone el procedimiento en cada una de las fases de las que consta el tratamiento, así como los resultados de su eficacia en un estudio de caso. Después de trece semanas de intervención se aprecian importantes cambios en el nivel de dependencia. Los resultados muestran una disminución significativa del tiempo de uso del ordenador y de juego, así como una mejoría del funcionamiento personal y social del paciente. This article provides a proposal of cognitive-be…

LEADERSHIP STYLES IN SYNCHRONOUS AND ASYNCHRONOUS VIRTUAL LEARNING ENVIRONMENTS
2013
A comparison of the effects of transactional and transformational leadership in synchronous and a synchronous online teamwork was conducted. In the study, groups of four participants interacted in online text chat and online text forum in problem solving tasks. The groups were leaded by a confederate who acted as a transactional or a transformational leader. Satisfaction in the interactions and participations communicative styles were assessed. Results indicated that transformational leadership is more satisfying and cognitive and metacognitive style oriented than transactional leadership that is more participative style oriented.
A Computationally Efficient Online/Offline Signature Scheme for Underwater Wireless Sensor Networks
2022
Underwater wireless sensor networks (UWSNs) have emerged as the most widely used wireless network infrastructure in many applications. Sensing nodes are frequently deployed in hostile aquatic environments in order to collect data on resources that are severely limited in terms of transmission time and bandwidth. Since underwater information is very sensitive and unique, the authentication of users is very important to access the data and information. UWSNs have unique communication and computation needs that are not met by the existing digital signature techniques. As a result, a lightweight signature scheme is required to meet the communication and computation requirements. In this researc…
Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…
2021
Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…
The Effects of General and Mobile Online Shopping Skilfulness and Multichannel Self-Efficacy on Consumer Showrooming Behaviour
2022
Although showrooming behaviour is a characteristic aspect of modern omnichannel retailing, our understanding of its antecedents remains limited. In this study, we aim to address this gap in prior research by examining how showrooming behaviour is affected by three different kinds of perceived consumer capabilities: general online shopping skilfulness, mobile online shopping skilfulness, and multichannel self-efficacy. The examination is done by utilising data from 1,024 Finnish consumers, which was collected with an online survey in 2021 and is analysed with structural equation modelling (SEM). In summary, we find mobile online shopping skilfulness to have a strong positive effect on showro…
Žargona un jauniešu valodas lietojums interneta ziņu rakstu komentāros
2017
Šajā darbā tiek pētīts žargona un jauniešu valodas lietojums interneta ziņu rakstu komentāros, kas ir publicēti sociālajā platformā facebook.com. Šī darba mērķis ir noskaidrot vai šo valodas slāņu lietojums var tikt uzskatīts par mehānismu, kas ļauj rakstītā tekstā paust emocijas, kuras komunicējot klātienē tiktu paustas caur mīmiku, žestiem un intonāciju. Pētījuma teorētiskajā daļā ir atrodams literatūras apraksts, tajā ir aprakstīts, kas ir žargons un kas jauniešu valoda, kādi valodas elementi tiem ir raksturīgi. Tāpat ir aprakstīta arī interneta vides ietekme uz valodas lietojumu un valodas funkcijas šajā kontekstā. Pētījuma empīriskajai daļā 291 komentārs tika analizēts izmantojot S. He…
