Over-ordering and food waste: The use of food delivery apps during a pandemic
2021
There is a paucity of research on the role of food delivery apps (FDAs) in food waste generation. This gap needs to be addressed since FDAs represent a fast-growing segment of the hospitality sector, which is already considered to be a key food waste generator globally. Even more critically, FDAs have become a prominent source of ordering food during the COVID-19 pandemic. In addition, the growing usage of FDAs warrants an improved understanding of the complexities of consumer behavior toward them, particularly during a health crisis. The present study addresses this need by examining the antecedents of FDA users’ food ordering behavior during the pandemic that can lead to food waste. The s…
Patterns of Teachers’ Occupational Well-Being During the COVID-19 Pandemic: Relations to Experiences of Exhaustion, Recovery, and Interactional Style…
2021
This study examined profiles of teachers’ occupational well-being during the COVID-19 pandemic. The data were collected from 279 Finnish primary school teachers during the spring of 2020. Four groups of teachers were identified by using Latent Profile Analysis: 1) teachers with mediocre stress and work engagement (34.4%);2) teachers with mediocre stress and lowest work engagement (11.5%);3) teachers with highest stress and work engagement (26.5%);and 4) teachers with lowest stress and highest work engagement (27.6%). The findings indicated that teachers’ occupational well-being was individually constructed, and there was a diversity with ways how negative and positive aspects of occupationa…
Digitalization and sustainability: virtual reality tourism in a post pandemic world
2022
The government-imposed COVID-19 pandemic control measures brought the tourism sector to a complete halt. However, virtual reality (VR) tourism offered people a way to escape the isolation. Media reports and research have noted heightened activity in VR tourism, which has been touted as “alternative tourism” and “eco-tourism”. However, scholars have yet to determine whether this shift is temporary or will persist after the pandemic is over. Questions also remain regarding the factors driving this behaviour. The present study uses stimulus-organism-response theory (SOR) to propose a sequential mechanism of the interplay of antecedents and outcomes, theorising VR tourism as a sustainable touri…
New delay-dependent stability conditions for time-varying delay systems
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/360924 Open Access This paper addresses the delay-dependent stability for systems with time-varying delay. First, by taking multi-integral terms into consideration, new Lyapunov-Krasovskii functional is defined. Second, in order to reduce the computational complexity of the main results, reciprocally convex approach and some special transformations are introduced, and new delay-dependent stability criteria are proposed, which are less conservative and have less decision variables than some previous results. Finally, two well-known example…
Essays on Corruption
2021
Paper III and Paper IV is not published yet. Corruption is blamed for reductions in operational efficiency, information asymmetry, limited income distribution, policy failure, and weak economic growth and development. Corruption can originate from either the “demand-side” (the recipients of the bribe) or the “supply-side” (the givers of the bribe). This double edge effect of corruption on the economy and society makes it a multidisciplinary subject and phenomenon. Thus, scholars from different fields and disciplines, such as finance, banking, economics, accounting, law, foreign aid, and international business, examined and analyzed corruption as a multidisciplinary subject. In this disserta…
Corruption in banks: A bibliometric review and agenda
2020
Abstract This paper is a bibliometric review of 819 articles, between 1969 and 2019, on corruption in banks. We identified six research streams: (1) the determinants of banks’ lending corruption; (2) the impact of corruption on banks’ lending and operational risk; (3) the impact of bank corruption on firms; (4) the impact of political connections on bank corruption; (5) the impact of corporate governance and regulations on bank corruption; and (6) the manipulation of the inter-bank offered rate. We recommend an anti-corruption architecture system and an extension in theoretical frameworks related to corruption in banks. We propose 20 future research questions.
How is motivational interviewing (un)related to self-determination theory: An empirical study from different healthcare settings.
2021
To explore how quality aspects and clients’ verbal behaviors in Motivational Interviewing sessions correspond with counsellors’ support of basic psychological needs described in Self-determination Theory, we conducted a mixed method study with quantitative analyses of transformed qualitative data from counselling sessions. Coding manuals identified if the counselling was consistent with Motivational Interviewing and the support of basic psychological needs. The study supported a conceptual relationship between motivational interviewing (MI) and self-determination theory (SDT), except for autonomy support which was conceptualized differently in the two approaches. Relational support in SDT a…

ObjectivesTo examine conditions and strategies to meet the challenges imposed by the coronavirus disease 2019 (COVID-19)-related visiting restrictions in Scandinavian intensive care units.Research methodology/designA cross-sectional survey.SettingAdult intensive care units in Denmark, Norway and Sweden.Main outcome measuresLikert scale responses and free-text comments within six areas: capacity and staffing, visiting policies and access to the unit, information and conferences with relatives, written information, children as relatives and follow-up initiatives.ResultsThe overall response rate was 53% (74/140 participating units). All intensive care units had planned for capacity extensions;…
Next-Day Bitcoin Price Forecast
2019
This study analyzes forecasts of Bitcoin price using the autoregressive integrated moving average (ARIMA) and neural network autoregression (NNAR) models. Employing the static forecast approach, we forecast next-day Bitcoin price both with and without re-estimation of the forecast model for each step. For cross-validation of forecast results, we consider two different training and test samples. In the first training-sample, NNAR performs better than ARIMA, while ARIMA outperforms NNAR in the second training-sample. Additionally, ARIMA with model re-estimation at each step outperforms NNAR in the two test-sample forecast periods. The Diebold Mariano test confirms the superiority of forecast …
Photoluminescence excited by ArF and KrF lasers and optical absorption of stishovite mono-crystal
2008
Two photoluminescence bands were found in a stishovite (silicon dioxide) mono-crystal sample under ArF (193 nm) and KrF (248 nm) excitation. The blue band is situated at 3.17 ± 0.02 eV in the case of ArF and at 3 ± 0.2 in the case of KrF. The UV band is at 4.55 ± 0.05 eV in the case of ArF and at 4.5 ± 0.05 eV in the case of KrF. The position of the UV emission band correlates with that excited by x rays. This position is 4.6 ± 0.05 eV with FWHM 0.8 ± 0.05 eV (Truhins et al 2003 Solid State Commun. 127 415). The blue band possesses slow decay kinetics with time constant 16 ± 2 µs and the UV band is fast on the level of 2 ± 0.5 ns, similarly for both lasers. Thermal quenching of both bands b…
