Stability of stochastic nonlinear systems with state-dependent switching

2013

In this paper, the problem of stability on stochastic systems with state-dependent switching is investigated. To analyze properties of the switched system by means of Itô’s formula and Dynkin’s formula, it is critical to show switching instants being stopping times. When the given active-region set can be replaced by its interior, the local solution of the switched system is constructed by defining a series of stopping times as switching instants, and the criteria on global existence and stability of solution are presented by Lyapunov approach. For the case where the active-region set can not be replaced by its interior, the switched systems do not necessarily have solutions, thereby quasi-…

A Research Agenda for Evaluating Strength of Internal Preferences and External Influences in Consumer Smartphone Switching

2015

This article proposes a research agenda to study what causes consumers to switch smartphone manufacturer and operating system brands. International consumer survey is planned for data collection and structural equation modeling method will be used to extrapolate whether internal preferences play a larger role than external influences in consumers’ switching behavior. The effects are expected to be moderated by behavioral control, subjective uncertainty and prior switching experience and controlled with a set of constraint variables. As a theoretical contribution, we propose a new theory to evaluate switching primarily through the latent construct of magnitude of switch. Potential practical …

[Optimization of systemic treatments for chronic plaque psoriasis. Recommendations for switching and transitioning.]

2014

The aim of this study was to provide practical recommendations for optimizing the use of conventional and biological systemic treatments for moderate-severe chronic plaque psoriasis, particularly in case of transitioning and switching.A total number of 147 dermatologists from 33 different countries including Italy achieved consensus in providing practical recommendations for the use of conventional and biological treatments for moderate to severe psoriasis based on systematic literature review and/or expert opinion.In general, the continuous treatment regimen should be preferred in order to achieve a complete and long-term control of psoriasis. However, the treatment could be stopped or the…

Why Do Users Switch Mobile Applications? : Trialing Behavior as a Predecessor of Switching Behavior

2018

Mobile application providers face high user losses because users can easily and often switch to an alternative application. Researchers have recently started to study information technology (IT) switching. However, no studies have concentrated on the unique context of mobile applications. Mobile application switching differs from the switching behavior related to many other IT products and services because of the highlighted role of alternatives, beta versions, updates, reviews, and users’ spontaneous behavior. To address this gap, we develop a mobile-specific model by using a qualitative research approach. As a theoretical contribution, we introduce trialing behavior as a predecessor of sw…

Personal use of technology at work : a literature review and a theoretical model for understanding how it affects employee job performance

2021

Employee personal use of technology at work (PUTW)—defined as employees’ activities using organisational or personal IT resources for non-work-related purposes while at work—is increasingly common in organisations. Our review of existing PUTW studies (n = 137) suggests that previous studies widely discussed PUTW outcomes, antecedents, and policies. The literature review also indicates that previous studies have proposed opposing viewpoints regarding the effect of PUTW on employee job performance, but few studies offered empirical evidence. Consequently, the conditions under which PUTW can increase or decrease employee job performance have not been discussed. We develop a theoretical model (…

Code-switching in a Finnish video game stream

2017

Tämä tutkielma käsittelee erään suomalaisen videopelaajan koodinvaihtoa suomen ja englannin kielen välillä suoratoistopalvelussa eli striimissä (engl. stream). Videopelin pelaamisen ja pelikavereilleen kommunikoimisen lisäksi striimaajiksi kutsutut henkilöt puhuttelevat myös yleisöään. Tutkimuksen kohteeksi valittiin yksi puolitoista tuntia kestävä istunto, jossa koodinvaihtoa tapahtuu runsaasti. Koodinvaihto englannin ja suomen välillä on yleistä pelattaessa videopelejä, joissa englannin kieli on vahvasti läsnä sekä visuaalisissa että auditiivisissa elementeissä. Tutkielman tarkoituksena oli selvittää, millaisia koodinvaihtotilanteita striimissä esiintyy ja mitä syitä niiden esiintymiselle…

Effect of pulse amplitude on depression and potentiation of ZrO2(Y)-based memristive synaptic device

2022

The effect of the amplitude of depressing and potentiating pulses on the synaptic plasticity (potentiation and depression) of a memristive device based on the Ta/ZrO2(Y)/Pt stack has been experimentally studied. It is shown that the amplitude of depressing and potentiating pulses affects the synaptic plasticity, namely, the value of current passing through the memristive device. The presented results demonstrate the prospects of using the ZrO2(Y)-based memristive devices as stable and low-power elements of neuromorphic systems.
