The hierarchy of needs for user experiences in virtual reality

2021

Virtual reality (VR) is rapidly becoming more widely adopted by various industries, and virtual content is just as rapidly becoming available for consumers. However, there is a lack of guidelines and standards for VR content to be held to in terms of experiential design. Because VR is a relatively new media form for consumers, there is a high risk of user attrition due to the novelty of the service. Therefore, if the first experience of the technology is with poorly made content, users will be much less likely to use VR again. Therefore, as various industries and organizations digitalize and adopt emerging technology such as VR, great care should be given to the way the virtual content and …

Low‐Valent Germanylidene Anions: Efficient Single‐Site Nucleophiles for Activation of Small Molecules

2021

Abstract Rare mononuclear and helical chain low‐valent germanylidene anions supported by cyclic (alkyl)(amino)carbene and hypermetallyl ligands were synthesised by stepwise reduction from corresponding germylene precursors via stable and isolable germanium radicals. The electronic structures of the anions can be described with ylidene and ylidone resonance forms with the Ge−C π‐electrons capable of binding even weak electrophiles. The germanylidene anions reacted with CO2 to give μ‐CO2‐κC:κO complexes, a rare coordination mode for low‐valent germanium and inaccessible for the related neutral germylones. These results implicate low‐valent germanylidene anions as efficient single‐site nucleop…

On the use of composite indicators for mobile communications network management in smart sustainable cities

2020

Beyond 5G networks will be fundamental towards enabling sustainable mobile communication networks. One of the most challenging scenarios will be met in ultra-dense networks that are deployed in densely populated areas. In this particular case, mobile network operators should benefit from new assessment metrics and data science tools to ensure an effective management of their networks. In fact, incorporating architectures allowing a cognitive network management framework could simplify processes and enhance the network&rsquo

Sistemi di comunicazione e dispositivi di interfaccia per l'integrazione della generazione distribuita nelle smart grids

2014

L'integrazione della generazione distribuita (GD) nelle reti elettriche di distribuzione a media e bassa tensione  uno degli elementi chiave per il pieno sfruttamento delle fonti energetiche rinnovabili (FER). Ci˜ implica un ripensamento della gestione e del controllo delle reti elettriche , che devono passare da sistemi " passivi ", con flussi di potenza unidirezionali e un numero limitato di funzioni di monitoraggio e automazione, a reti attive e intelligenti (Òsmart gridsÒ). In tali sistemi, i flussi di potenza possono essere bi-direzionali e, se non correttamente gestiti, possono causare situazioni critiche, quali ad es. problemi di stabilitˆ e di controllo della rete o funzionamento i…

Enhancing the Iterative Smoothed Particle Hydrodynamics Method

2021

Motivated by recent research on the iterative approach proposed for the smoothed particle hydrodynamics (ISPH) method, some ideas to improve the process are introduced. The standard procedure is enhanced iterating on the residuals preserving the matrix-free nature of the process. The method is appealing providing reasonable results with disordered data distribution too and no kernel variations are needed in the approximation. This work moves forward with a novel formulation requiring a lower number of iterations to reach a desired accuracy. The computational procedure is described and some results are introduced to appreciate the proposed formulation.

Utilizing ICT to prevent loneliness and social isolation of the elderly. A literature review

2016

Ageing of the population is a worldwide phenomenon. Numerous ICT-based solutions have been developed for elderly care but mainly connected to the physiological and nursing aspects in services for the elderly. Social work is a profession that should pay attention to the comprehensive wellbeing and social needs of the elderly. Many people experience loneliness and depression in their old age, either as a result of living alone or due to a lack of close family ties and reduced connections with their culture of origin, which results in an inability to participate actively in community activities (Singh & Misra, 2009). Participation in society would enhance the quality of life. With the deve…

The Role of Social Media Influencers in Public Health Communication: Case COVID-19 Pandemic

2022

During public health crises, public organizations face a variety of strategic communication challenges, and the outbreak of the COVID-19 pandemic in 2020 is an extreme example. In Finland, the Prime Minister’s Office initiated a communication campaign that utilized social media influencers to communicate timely instructions regarding the pandemic. However, it is uncertain how social media influencers adapt to briefings of public organizations given that they typically work with brands that align with their own interests and expertise, which rarely is epidemiology. We use the two-step flow of communication model and social influence theory to analyze research data that consisted of 96 Instag…

Newspapers and Cross-Level Communications on Social Media : A comparative study of Japan, Korea, and Finland

2017

In order to examine how the same types of social media are perceived and utilized in different national contexts for journalism and news media, we studied mainstream newspapers in three countries where both newspapers and social media are viable: Japan, Korea, and Finland. Our in-depth interviews with journalists indicate both similarities and differences in the three countries. The most outstanding similarity is that newspapers have not fully incorporated cross-level communications available on social media platforms. Factors related to organizational structures, goals, policies, and procedures served as filters for the incorporation of social media into the news production and distributio…

Choosing the Right Medium for Municipal eParticipation Based on Stakeholder Expectations

2012

Published version of a chapter in the book: Electronic Participation. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-33250-0_3 This paper examines the expectations and communication needs of relevant stakeholder groups for municipal eParticipation in a small Norwegian municipality. We identified relevant stakeholder groups with the municipality, and asked them about their communication preferences through a combined Delphi study and survey approach. The findings show that information about local issues, information about issues relevant for the individual stakeholder, and dialogue on business’ needs and employment are the three most important communication needs. …
