Digital Activism in Russia: The Evolution and Forms of Online Participation in an Authoritarian State
2020
AbstractThis chapter describes how digitalization has affected activism in Russia by tracing the evolution, particularity, and the most visible forms of online activism in the context of the increasingly authoritarian Russian state. It discusses online activism in relation to “connective action” and illustrates it with two examples of contentious political activism: the anti-corruption campaign led by Alexei Navalny and the struggle to protect online communication from state surveillance by the Telegram messenger service. In addition, the chapter presents examples of Russian activism, which do not directly challenge the Kremlin.
Usage of Facebook- and Anonymous Forum–Based Peer Support Groups Online and Their Influence on Perceived Social Support Types in Weight Loss
2016
This paper contributes to the discussion on health behavior change support systems by examining one of the persuasive software features, social support. The paper studies the influence of structural social support on functional social support types in the online environment. Specifically, the paper examines the frequency of using two different kinds of online social platforms (online forums and Facebook groups) that are used to facilitate peer social support in weight loss and their influence on perceived functional social support types (emotional, informational, and instrumental). The results show that frequent use of Facebook based support peer group facilitates perceived emotional, infor…
Cultural heritage in social media : Museum of Photography
2012
The research Cultural Heritage in Social Media: Museum of Photography deals with a new form of displaying and preserving cultural heritage in the 21st century by using social media tools. This paper is an analysis of a Romanian cultural heritage blog, Museum of Photography, which contains documentary photography from the end of the 19th century until 1990’s as well as other types of photographs related to the interests’ of Alex Galmeanu – the owner of Museum of Photography. The aim of this research is to demonstrate that cultural heritage exists outside the boundaries of formal institutions, namely museums, thus showing that the meaning of the word “museum” is expanding and that the public …
Tiešsaistes spēles (ne)produktivitāte: gadījuma pētījums par radošumu
2022
Bakalaura pētījums “Tiešsaistes spēles (ne)produktivitāte: gadījuma pētījums par radošumu” fokusējās uz radošajiem procesiem, ko piedzīvo galda spēles Dungeons and Dragons spēlētāji veidojot virtuālās pasaules un veidiem kā radošums izpaužas, kad spēle ir situēta tiešsaistes vidē. Iesaistoties Dungeons and Dragons kopienā, izmantojot līdzdalīgu novērojumu, neformālas diskusijas un daļēji strukturētas intervijas, es pētu dažādus artefaktu veidošanās procesus un digitālo tehnoloģiju ietekmi uz mūsu socializāciju tiešsaistē. Radošums ir improvizēts un ir mūsu sociālās un kultūras dzīves neatņemama sastāvdaļa, kas veido gan mūs pašus, gan esošās struktūras.
Game-Theoretic Approach to Hölder Regularity for PDEs Involving Eigenvalues of the Hessian
2021
AbstractWe prove a local Hölder estimate for any exponent $0<\delta <\frac {1}{2}$ 0 < δ < 1 2 for solutions of the dynamic programming principle $$ \begin{array}{@{}rcl@{}} u^{\varepsilon} (x) = \sum\limits_{j=1}^{n} \alpha_{j} \underset{\dim(S)=j}{\inf} \underset{|v|=1}{\underset{v\in S}{\sup}} \frac{u^{\varepsilon} (x + \varepsilon v) + u^{\varepsilon} (x - \varepsilon v)}{2} \end{array} $$ u ε ( x ) = ∑ j = 1 n α j inf dim ( S ) = j sup v ∈ S | v | = 1 u ε ( x + ε v ) + u ε ( x − ε v ) 2 with α1,αn > 0 and α2,⋯ ,αn− 1 ≥ 0. The proof is based on a new coupling idea from game theory. As an application, we get the same regularity estimate for viscosity solutions of the PDE $…
Regularity for nonlinear stochastic games
2015
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed
Passive Control of Linear Structures Equipped with non-Linear Viscous Dampers and Amplification Mechanism
2008
Fluid damper devices in civil structures such as buildings or bridges are commonly used as energy absorbers for seismic protection. The problem in the response analysis of structures with filled dampers mainly consists in the fact that, due to the strongly nonlinear behavior of such equipments, the response spectrum technique fails. Moreover, in order to enhance the damping effect various toggle brace configurations have been recently proposed. In this paper by using the concept of power spectral density function compatible with the elastic response spectrum and the stochastic linearization technique, the equivalent damping ratio is obtained. It is shown that once the system is linearized r…
Identity construction in the comments section of TomandLorenzo.com
2016
Virtual spaces as sites of social interactions and therefore identity work have become common over the past few decades. Alongside, research focus on such spaces has increased. This MA thesis constitutes a small contribution to the study of interactional identity building through computer mediated communication. The study was conducted on data gathered from a subsection of popular-culture blog tomandlorenzo. The aim was to identify how interactants in this space interactively work their identities. The qualitative discourse analysis focused on three mechanics of identity building, those of indexicality, performativity and stance taking. The investigation also took the influence of the mediu…
Singing is what we do (together) - redefining "together" : A comparative study
2021
This article discusses the impact that the Covid-19 pandemic has had on singing with children in schools by providing a descriptive analysis of a comparative look at children's experiences of their singing habits and emotional well-being during the first Covid-19 lockdown. Covid-19 has established itself as (for now) an ever-present variable in our daily lives. This paper offers a descriptive analysis of a comparative study of the Covid-19 lockdown(s) influence on children's singing habits and emotional well-being in Italy, Austria, and Finland. A survey was carried out on children and young people aged 10-20 from Austria, Finland, and Italy on how the Coronavirus lockdown has impacted thei…
A Customer Perspective on Omnichannel Customer Journey and Channel Usage : A Qualitative Study
2022
This qualitative study investigates customer behavior during the omnichannel customer journey. The study aims to increase the understanding of omnichannel service environments from a customer-centric point of view. The data was collected by interviewing 10 young adults (from 26 to 30 years old) who had bought a Finnish clothing brand (R-Collection) product via a digital or a physical channel. The research interviews dealt with the interviewees' experiences and channel behavior during their shopping journeys. Our results reflect the multidimensional nature of the omnichannel customer journey and give interesting insights into the usage of digital channels and technologies for clothing shoppi…
