Time-delay control for stabilization of the Shapovalov mid-size firm model
2020
Control and stabilization of irregular and unstable behavior of dynamic systems (including chaotic processes) are interdisciplinary problems of interest to a variety of scientific fields and applications. Using the control methods allows improvements in forecasting the dynamics of unstable economic processes and offers opportunities for governments, central banks, and other policy makers to modify the behaviour of the economic system to achieve its best performance. One effective method for control of chaos and computation of unstable periodic orbits (UPOs) is the unstable delay feedback control (UDFC) approach, suggested by K. Pyragas. This paper proposes the application of the Pyragas' me…
D3 Dihedral Logistic Map of Fractional Order
2021
In this paper, the D3 dihedral logistic map of fractional order is introduced. The map presents a dihedral symmetry D3. It is numerically shown that the construction and interpretation of the bifurcation diagram versus the fractional order requires special attention. The system stability is determined and the problem of hidden attractors is analyzed. Furthermore, analytical and numerical results show that the chaotic attractor of integer order, with D3 symmetries, looses its symmetry in the fractional-order variant.
The Lorenz system : hidden boundary of practical stability and the Lyapunov dimension
2020
On the example of the famous Lorenz system, the difficulties and opportunities of reliable numerical analysis of chaotic dynamical systems are discussed in this article. For the Lorenz system, the boundaries of global stability are estimated and the difficulties of numerically studying the birth of self-excited and hidden attractors, caused by the loss of global stability, are discussed. The problem of reliable numerical computation of the finite-time Lyapunov dimension along the trajectories over large time intervals is discussed. Estimating the Lyapunov dimension of attractors via the Pyragas time-delayed feedback control technique and the Leonov method is demonstrated. Taking into accoun…
The Role of Anticipated Guilt and its Neutralisation in Explaining Responsible Online Shopping
2023
Although responsible consumption has been the target of growing interest in academic research, the antecedents of responsible online shopping remain poorly understood. In this study, we address this gap in prior research by focusing on the role of anticipated guilt in explaining responsible online shopping. By using data from 479 Finnish consumers, we aim to answer two research questions: (1) how strong an antecedent of responsible online shopping intention is anticipated guilt in relation to other potential antecedents and (2) how efficiently can consumers regulate their resulting feelings of guilt by using different kinds of neutralisation techniques? We find anticipated guilt to be a str…
Opettajaopiskelijoiden kielitoinen toimijuus monikielisten oppijoiden etäohjauksessa
2022
Artikkelissa tarkastellaan opettajaopiskelijoiden kielitietoista toimijuutta ohjaustilanteessa, jossa he tukevat etäyhteyksin eri-ikäisiä monikielisiä oppijoita. Ennestään tuntemattomien monikielisten oppijoiden ohjaaminen etäyhteyksin oli opettajaopiskelijoille uusi ja haastava tilanne pandemiakriisissä vuonna 2020. Tutkimuksen aineistona on yhdentoista opettajaopiskelijan ohjaustehtävästä kirjoittamat raportit, jotka on analysoitu aineistolähtöisen temaattisen analyysin keinoin. Analyysissa tarkasteltiin seikkoja, jotka mahdollistavat ja rajoittavat varhaiskasvatuksen, luokanopettajakoulutuksen ja kielten aineenopettajakoulutuksen opiskelijoiden kielitietoista toimijuutta monikielisten op…
The Cross-Channel Effects of In-Store Customer Experience in the Case of Omnichannel Fashion Retailing in Finland
2023
Although omnichannel retailing has emerged as a popular research topic in academic research, there are still gaps in our understanding of this phenomenon. One such gap concerns omnichannel customer experience and particularly the cross-channel or spillover effects of how customer experience in one channel may affect customer behaviour not only in that specific channel but also in the other channels of the same retailer. In this study, we aim to address this gap by examining how customer experience in the offline channel affects customer behaviour in both the offline and the online channel, more specifically how in-store customer experience affects both brick-and-mortar store and online stor…
Our aim is to transfer life-saving knowledge to large numbers of responders: Knowledge Dissemination in the E-health Era
2020
The origin of ‘public health’ discourse goes back to the 19th century when ideas of health and wellness began to take hold as an academic discipline at universities first in Europe (France and UK), and then in US. As scientific knowledge grew, public authorities were more concerned on general sanitation (Chave 1984) and gradually were formed to employ newly discovered interventions against health threats. The principles of public health in earlier times were guided more by the notions of the commons, wellbeing, and local knowledge. In recent times, our understanding and practice of public health is guided more by technological advances generally based on governmental decisions (Green et. al…
Rozwój kompetencji społecznych studentów w dobie nauczania online
2021
Artykuł jest komunikatem z badań, których celem była próba odpowiedzi na pytanie, jak studenci oceniają rozwój swoich kompetencji społecznych w związku z nauką online, która stała się koniecznością z powodu pandemii COVID19. W badaniu wzięło udział 350 studentów z trzech uczelni wyższych miasta Opola. Posłużono się metodą sondażu diagnostycznego. W celu zgromadzenia materiału badawczego wykorzystano kwestionariusz ankiety własnego autorstwa, w wersji online. Badani odpowiadali na pytania w oparciu o pięciostopniową skalę. Analiza wyników wskazuje na to, że respondenci najwyżej ocenili umiejętność zarządzania sobą w czasie (M=3,71) oraz umiejętność wyrażania własnego zdania (M=3,66), natomi…
Korpuspohjaista oppijansanakirjaa tekemässä: esimerkkiinä ConLexis
2013
Artikkelimme käsittelee korpuspohjaisia oppijansanakirjoja. Sähköisiin aineistoihin ja kielenkäytöstä hankittuun tutkimukselliseen tietoon perustuvat sanakirjat ovat edelleen harvinaisia, ja kielenoppijoille niitä on tarjolla hyvin vähän. Suomesta tällaisia sanakirjoja ei ole ollut lainkaan. Esittelemme yleisesti oppijoille suunnattujen sähköisten sanakirjojen vaatimuksia ja tarkemmin uuden tekeillä olevan ConLexis-verkkosanakirjan suunnittelutyötä, tavoitteita ja sisältöä. ConLexis on suunnattu B1-tason ja sitä edistyneemmille kielenoppijoille, mutta sitä voivat opettajat käyttää opetuksensa tukena alemmillakin taitotasoilla. Sana-artikkeleissa esitetty tieto perustuu laajoihin korpusanaly…
Online authority communication during an epidemic : A Finnish example
2011
Social media is creating new challenges for authority communications during crises, such as a pandemic. This study examined Finnish citizens’ opinions about authorities as crisis managers during the swine flu epidemic of 2009-2010 and examined the success of authority intervention to online discussion forums. Through a content analysis carried out at the discussion forums, the study showed that though authorities are highly trusted in general in Finland, this trust is not extended to the online environment. Online, civilians did not trust authorities and the protective actions taken. Moreover, the authorities’ intervention to the discussion forums aimed at correcting false information and s…
