- Although several studies have extensively discussed the role of intrapreneurs, individuals’ experiences of intrapreneurial processes in the academic context remain largely unexplored. The prominence of intrapreneurial logic in academia has led to increased institutional complexity and highlighting the need for an improved understanding of how to navigate multiple logics present at individual, organizational, and field levels to attain the desired intrapreneurial outcomes. To address these challenges, we propose an integrative framework that captures both organizational and individual-level responses to these multiple logics, while also incorporating intrapreneurial logic. Upon analyzing data from nineteen intrapreneurs across three universities, this study reveals that universities actively uphold the academic logic that intrapreneurs identify as a barrier, compelling them to refine their skills and actively hybridize logics by integrating multiple specific elements of intrapreneurship, teaching, and research. Simultaneously, universities incorporate intrapreneurial logic into their operational processes, even combining multiple logics, which intrapreneurs leverage within their own activities to push their ideas forward. The study offers implications for intrapreneurship literature, academic management, and policymakers to more effectively foster intrapreneurial activities.

- The anomalous temperature dependence of elastic constant c(44) for elements V. Nb, Ta, Pd, and Pt, has been calculated using first-principles theory. It is shown that the variation of elastic constant for simple elements can be approximated as the sum of thermal expansion and electronic components. The thermal expansion contributes the normal linearly decreasing effect to the elastic constant with temperature, while electronic contribution is determined by the unique character of electronic structure of elements and leads to the anomalous effect to the elastic constant with temperature.

- We have studied In-stabilized c(8 2)-reconstructed InAs(1 0 0) and InSb(1 0 0) semiconductor surfaces, which play a key role in growing improved III-V interfaces for electronics devices, by core-level photoelectron spectroscopy and first-principles calculations. The calculated surface core-level shifts (SCLSs) for the zeta and zeta a models, which have been previously established to describe the atomic structures of the III-V(1 00)c(8 x 2) surfaces, yield hitherto not reported interpretation for the As 3d, In 4d, and Sb 4d core-level spectra of the III-V(1 00)c(8 x 2) surfaces, concerning the number and origins of SCLSs. The fitting analysis of the measured spectra with the calculated zeta and zeta a SCLS values shows that the InSb spectra are reproduced by the zeta SCLSs better than by the zeta a SCLSs. Interestingly, the zeta a fits agree better with the InAs spectra than the zeta fits do, indicating that the zeta a model describes the InAs surface better than the InSb surface. These results are in agreement with previous X-ray diffraction data. Furthermore, an introduction of the complete-screening model, which includes both the initial and final state effects, does not improve the fitting of the InSb spectra, proposing the suitability of the initial-state model for the SCLSs of the III-V(1 0 0)c(8 x 2) surfaces. The found SCLSs are discussed with the ab initio on-site charges.

Intentional electromagnetic interference (IEMI) : Susceptibility investigations and classification of civilian systems and equipment
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This PhD thesis addresses the threat posed to society by sources that can produce high power electromagnetic pulses (HEPM) and be used maliciously to disturb or damage electronic equipment. The vulnerability from intentional electromagnetic interference (IEMI) has increased in the recent decades due to the widespread dependence of the civil society on sensitive electronic systems and proliferation of radiation sources. As the characteristics of the disturbances associated with IEMI often have very high frequency content, the existing mitigation measures and protection components may not be adequate. It was seen that for ultra wideband (UWB) transients low voltage protection components may not work as intended, due to parasitic components that arises from the packaging of the device. The large spatial distribution of many civilian facilities and critical infra-structures (e.g., power generation, communications, train system, etc.) presents many unexpected ports for an attacker as the majority of the parts of these systems are not protected or secure. As the new European Rail Traffic Management System (ERTMS) will utilize wireless communication for communication and control of the trains the vulnerability from different radiating HPEM sources was investigated. Angles of incidence and frequencies that are a threat in a given situation are identified. Due to the possibility of unexpected ports, the propagation of differential mode ultra wideband transients in low voltage power networks, when injected into a power socket of a facility, was studied. The effects on the transient propagation from cable bends, switches and junctions were studied, both in a laboratory setup and in the network of a facility. Also, as modern electronic equipment and systems may not be tested for waveforms and disturbances other than standardized EMC tests, experiments on some common commercial-off-the-shelf (COTS) equipment were performed with non-standard test situation. It was seen that these could easily be disturbed or even permanently damaged. In addition, due to the inherent difficulties with IEMI, a new method for classifying facilities from IEMI is suggested. It is based on available terminology of accessibility (A), susceptibility (S) and consequence (C), but expands these and forms the so called IEMI/ASC-cube.

- PurposeGamification applications (apps) are gaining great attention in many contexts and have grown increasingly. Despite their significant role in many settings, prior research mainly focused on initial adoption, and there are limited studies on the post-adoption stage. This study aims to explore the factors influencing individuals' continuance intention to use gamified task manager apps, drawing on the technology continuance theory (TCT) by integrating enjoyment, habit and social influence. Design/methodology/approachData were obtained from 318 Malaysian who had prior experience with task management gamified apps and analysed with the partial least squares approach. FindingsAccording to the results, confirmation, perceived usefulness (PU) and enjoyment positively influence satisfaction. PU, enjoyment, satisfaction and social influence affect attitude, while the result failed to confirm the association between perceived ease of use and attitude. Furthermore, PU, attitude and habit are strong determinants of users' continuance intention. Moreover, continuance intention was not predicted by users' satisfaction and social influence. Practical implicationsThe findings provide directions for developers and marketers of gamified task manager apps. Besides the technological and functional benefits of applications, they should also consider social, hedonic and individual factors in the designing and marketing stages. Originality/valueThis study extends the literature by assessing the determinants of continuous intention to use gamified task manager apps; and extending the TCT in the context of gamification by incorporating three contextual factors, namely, perceived enjoyment, social influence and habit.

Tidskriftsartikel (refereegranskat)abstract
- In this paper we present a study on the effects of auditory- and haptic feedback in a virtual throwing task performed with a point-based haptic device. The main research objective was to investigate if and how task performance and perceived intuitiveness is affected when interactive sonification and/or haptic feedback is used to provide real-time feedback about a movement performed in a 3D virtual environment. Emphasis was put on task solving efficiency and subjective accounts of participants’ experiences of the multimodal interaction in different conditions. The experiment used a within-subjects design in which the participants solved the same task in different conditions: visual-only, visuohaptic, audiovisual and audiovisuohaptic. Two different sound models were implemented and compared. Significantly lower error rates were obtained in the audiovisuohaptic condition involving movement sonification based on a physical model of friction, compared to the visual-only condition. Moreover, a significant increase in perceived intuitiveness was observed for most conditions involving haptic and/or auditory feedback, compared to the visual-only condition. The main finding of this study is that multimodal feedback can not only improve perceived intuitiveness of an interface but that certain combinations of haptic feedback and movement sonification can also contribute with performance-enhancing properties. This highlights the importance of carefully designing feedback combinations for interactive applications.

- Programmable robots are increasingly used to introduce computational thinking and programming to young children. However, how to practically introduce this is still being developed, where storytelling and project-based methods have been promoted as possible ways to achieve this. This paper presents a study from a preschool featuring 4–5 year-olds working with a Ukrainian folk tale, The Mitten, while introducing programming through a programmable floor robot, The Blue-Bot. The paper presents the iterative cycles during a design-based study of merging the folk tale with the Blue-Bot during the project. The paper further examines the educational affordances of a programming board created during the project, showing how the folk tale provided a fitting structure for the board and pedagogical scaffold during the activities. The paper discusses how older forms of cultural heritage can be merged with new technologies and the added importance of the particular case of Ukrainian cultural heritage following the outbreak of the war in Ukraine.

Tidskriftsartikel (refereegranskat)abstract
- Digital devices such as iPads are prevalent in children’s play from an early age. How this shapes young children’s play is an area of considerable debate without any clear consensus on how different forms of play are brought into the iPad interaction. In this study, we examined 98 play activities of children in two preschool settings, featuring 2 and 4–5-year-olds, their play with iPads and non-digital artefacts. Three analytical approaches were used: an index built on a digital play framework (Bird, Jo, and Susan Edwards. 2015), a quantitative description of the index, and a qualitative interaction analysis of children’s play. Results show how play with iPads is characterised as less ludic than play with other artefacts, and diverges from the age-typical norms of play. We discuss what these results might mean for children’s play in contemporary early childhood settings and for children’s learning.
