Collecting and Using Students’ Digital Well-Being Data in Multidisciplinary Teaching

2018

This article examines how students (N=198; aged 13 to 17) experienced the new methods for sensor-based learning in multidisciplinary teaching in lower and upper secondary education that combine the use of new sensor technology and learning from self-produced well-being data. The aim was to explore how students perceived new methods from the point of view of their learning and did the teaching methods provide new information that could promote their own well-being. We also aimed to find out how to collect digital well-being data from a large number of students and how the collected big data set can be utilized to predict school success from the students’ well-being data by using machine lear…

Ultradeep Sequencing Analysis of Population Dynamics of Virus Escape Mutants in RNAi-Mediated Resistant Plants

2012

Plant artificial micro-RNAs (amiRs) have been engineered to target viral genomes and induce their degradation. However, the exceptional evolutionary plasticity of RNA viruses threatens the durability of the resistance conferred by these amiRs. It has recently been shown that viral populations not experiencing strong selective pressure from an antiviral amiR may already contain enough genetic variability in the target sequence to escape plant resistance in an almost deterministic manner. Furthermore, it has also been shown that viral populations exposed to subinhibitory concentrations of the antiviral amiR speed up this process. In this article, we have characterized the molecular evolutiona…

Organizational information and communication technologies and their influence on communication visibility and perceived proximity

2021

This study investigates the relationships between the use of various organizational ICTs, communication visibility, and perceived proximity to distant colleagues. In addition, this study examines the interplay between visibility and proximity, to determine whether visibility improves proximity, or vice versa. These relationships are tested in a global company using two waves of panel survey data. ESM use increases communication visibility and perceived proximity, while controlling for prior levels of visibility, proximity, and the use of other organizational ICTs. The influence of ESM on network translucence and perceived proximity is generally stronger than the impact of other technologie…

Communication strategies used by 'British Petroleum (BP)' to deal with legitimacy before and after the Deepwater Horizon Accident

2016

Oil spills pose serious threats to the legitimacy of the companies involved and the oil industry in general. The objective of this study is to conduct research on the communication strategies used by ‘British Petroleum’ (BP) to maintain its legitimacy before the Deepwater Horizon (DH) oil spill caused in April 2010 and to repair its legitimacy after the DH accident. There is existing literature on the legitimacy theory and the communication strategies as well as DH accident and its causes. A qualitative study based on the sustainability reports of BP from 2006 to 2015 and its press releases in relation to the DH accident from April 2010 to April 2016 is conducted to discover its preferred c…

Rahoitusmarkkinainformaatio BRIC-maiden laajennetussa Taylorin säännössä

2017

Tutkielmassa tarkastellaan BRIC-maiden harjoittamaa rahapolitiikkaa vuosina 2005-2015. Tutkielman päämääränä on selvittää, ovatko keskuspankit reagoineet rahapolitiikallaan inflaation ja tuotantokuilun lisäksi myös rahoitusmarkkinainformaatioon. Aineistona on käytetty reaaliaikaista aineistoa inflaation ja tuotantokuilun osalta. Rahoitusmarkkinainformaatiolla tarkoitetaan tutkielmassa kohdemaan valuuttakurssia ja keskimääräistä osinkotuottoa. Rahapolitiikkaa on arvioitu sekä sen hetkisten että eteenpäin katsovien Taylorin sääntöjen avulla. Rahoitusmarkkinainformaation roolia on tutkittu estimoimalla erilaisia rahoitusmarkkinainformaatiolla laajennettuja Taylorin sääntöjä ja arvioimalla laaj…

The pricing capability lifecycle of digital innovations

2021

The pricing capability provides a basis for firms’ competitive advantage. However, to date, the literature has not investigated how this capability forms, develops, and matures. In this study, we define the pricing capability as a dynamic capability consisting of three operational building blocks (tools and data, human and relational resources, and processes, routines, and mechanisms) as well as two dynamic capability building blocks (alertness and responsiveness, and value-based strategic thinking). Furthermore, we propose the pricing capability lifecycle of digital innovations that incorporates insights of the dynamic capabilities view (DCV). Based on a longitudinal multi-case study of fi…

Adolescents' school-related self-concept mediates motor skills and psychosocial well-being.

2014

Background The health benefits of exercise participation and physical activity for mental health and psychosocial well-being (PSWB) have been shown in several studies. However, one important background factor, that is, motor skills (MSs), has largely been ignored. In addition, most of the existing research focuses on poor MSs, that is, poor MSs are often connected to poorer PSWB. The mechanism linking MSs and PSWB is unclear. However, a preliminary suggestion has been made that self-worth or self-perceptions might mediate the association between MSs and PSWB. Aim We investigated whether the self-concepts (SCs) of school-related physical education (SCPE), reading (SCR), and mathematics (SCM)…

Risk perception and gratitude mediate the negative relationship between COVID-19 management satisfaction and public anxiety

2023

AbstractIn this study, we explored whether satisfaction with government management, perception of risk, and gratitude influenced public anxiety during the COVID-19 pandemic in China. Using a cross-sectional, anonymous and confidential online survey, a nationwide sample of Chinese adults (N = 876) was targeted between March 25–March 30, 2020, a period in which newly confirmed cases significantly declined in China. The anxiety level was decreased as compared to that assessed during the peak period. Multiple parallel mediation modeling demonstrated that risk perception and gratitude partially mediated the relationship between satisfaction with government management and public anxiety. Increasi…
