- This study examines the influence of cultural regions on the interdependence between delegation of authority and other management control (MC) practices. In particular, we assess whether one of the central contentions of agency theory, that incentive contracting and delegation are jointly determined, holds in different cultural regions. Drawing on prior literature, we hypothesise that the MC practices that operate as a complement to delegation vary depending on societal values and preferences, and that MC practices other than incentive contracting will complement delegation in firms in non-Anglo cultural regions. Using data collected from 584 strategic business units across three Western cultural regions (Anglo, Germanic, Nordic), our results show that the interdependence between delegation and incentive contracting is confined to Anglo firms. In the Nordic and Germanic regions, we find that strategic and action planning participation operate as a complement to delegation, while delegation is also complemented by manager selection in Nordic firms. Overall, our study demonstrates that cultural values and preferences significantly influence MC interdependence, and suggests that caution needs to be taken in making cross-cultural generalisations about the complementarity of MC practices.

- Objective Some immunomodulatory drugs have been shown to delay the onset of, or lower the risk of developing, rheumatoid arthritis (RA), if given to individuals at risk. Several trials are ongoing in this area; however, little evidence is currently available about the views of those at risk of RA regarding preventive treatment. Method Three focus groups and three interviews explored factors that are relevant to first degree relatives (FDRs) of RA patients and members of the general public when considering taking preventive treatment for RA. The semi-structured qualitative interview prompts explored participant responses to hypothetical attributes of preventive RA medicines. Transcripts of focus group/interview proceedings were inductively coded and analysed using a framework approach. Results Twenty-one individuals (five FDRs, 16 members of the general public) took part in the study. Ten broad themes were identified describing factors that participants felt would influence their decisions about whether to take preventive treatment if they were at increased risk of RA. These related either directly to features of the specific treatment or to other factors, including personal characteristics, attitude towards taking medication, and an individual's actual risk of developing RA. Conclusion This research highlights the importance of non-treatment factors in the decision-making process around preventive treatments, and will inform recruitment to clinical trials as well as information to support shared decision making by those considering preventive treatment. Studies of treatment preferences in individuals with a confirmed high risk of RA would further inform clinical trial design.

- In the era of the IoT revolution, applications are becoming ever more sophisticated and accompanied by diverse functional and non-functional requirements, including those related to computing resources and performance levels. Such requirements make the development and implementation of these applications complex and challenging. Computing models, such as cloud computing, can provide applications with on-demand computation and storage resources to meet their needs. Although cloud computing is a great enabler for IoT and endpoint devices, its limitations make it unsuitable to fulfill all design goals of novel applications and use cases. Instead of only relying on cloud computing, leveraging and integrating resources at different layers (like IoT, edge, and cloud) is necessary to form and utilize a computing continuum. The layers’ integration in the computing continuum offers a wide range of innovative services, but it introduces new challenges (e.g., monitoring performance and ensuring security) that need to be investigated. A better grasp and more profound understanding of the computing continuum can guide researchers and developers in tackling and overcoming such challenges. Thus, this paper provides a comprehensive and unified view of the computing continuum. The paper discusses computing models in general with a focus on cloud computing, the computing models that emerged beyond the cloud, and the communication technologies that enable computing in the continuum. In addition, two novel reference architectures are presented in this work: one for edge–cloud computing models and the other for edge–cloud communication technologies. We demonstrate real use cases from different application domains (like industry and science) to validate the proposed reference architectures, and we show how these use cases map onto the reference architectures. Finally, the paper highlights key points that express the authors’ vision about efficiently enabling and utilizing the computing continuum in the future.

- Objective: The Job Demand Control model presents combinations of working conditions that may facilitate learning, the active learning hypothesis, or have detrimental effects on health, the strain hypothesis. To test the active learning hypothesis, this study analysed the effects of job demands and job control on general problem-solving strategies. Participants: A population-based sample of 4,636 individuals (55% women, 45% men) with the same job characteristics measured at two times with a three year time lag was used. Methods: Main effects of demands, skill discretion, task authority and control, and the combined effects of demands and control were analysed in logistic regressions, on four outcomes representing general problem-solving strategies. Results: Those reporting high on skill discretion, task authority and control, as well as those reporting high demand/high control and low demand/high control job characteristics were more likely to state using problem solving strategies. Conclusions: Results suggest that working conditions including high levels of control may affect how individuals cope with problems and that workplace characteristics may affect behaviour in the non-work domain.

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this study was to contribute with knowledge about the tension between preschool teachers' mission to teach and support children's learning on the one hand and the mission to assess children's learning processes on the other hand, in relation to equality in education. In Swedish preschools, children with different experiences meet, all of whom should have the opportunity to develop and learn based on their varied circumstances and needs. According to the Education Act (SFS, 2010:800), preschool education must be equal, and all children must have the opportunity to learn and develop as far as possible based on their potential. However, previous research (Alasuutari, Vallberg Roth & Markström, 2014) indicates that assessment involves risks for children’s identity creation. This study examines how seven preschool teachers tackle the challenge of assessing and paying attention to individual children in their ongoing learning processes. A sociocultural perspective (Vygotskij, 1978) has been used to study preschool teachers' reasoning about assessment in relation to each child's possibilities for being supported in their proximal development zone. The sociocultural perspective stresses the importance of cultural tools for communication. Stimulated-recall interviews were conducted with seven preschool teachers in Sweden. Content analysis was used to reveal the views that emerged in preschool teachers’ descriptions.In the preschool teachers' reasoning, different strategies for assessment and methods for making the child's learning processes visible as well as approaches for following the progression in children's learning processes have emerged, which can create both opportunities and limitations for children to learn based on their potential. Findings indicate three areas significant for assessment in relation to an equivalent education in this study. Firstly, there is clarity regarding the approach to assessment, what is to be given attention and assessed and how the assessment should be carried out. Secondly, the preschool teachers in the study have knowledge about various methods to make children's learning processes visible and thus possible to follow over time. Thirdly, the preschool teachers in the study know how to draw attention to and make visible the child's learning from a holistic perspective. The Licentiate thesis highlights different strategies for assessment, methods for making the child's learning processes visible and approaches for following the progression in children's learning processes that emerged during the preschool teachers' reasoning. The study has shown that attentiveness (Elbaz, 1992) can be used as a concept to bridge the tension surrounding assessment.

Tidskriftsartikel (refereegranskat)abstract
- The adsorption of Ni2+, Cd2+, PO4 3- and NO3 - by carbonated hydroxyapatite (CHA) modified microfibrillated cellulose (MFC) was studied in the aqueous solution. The modified adsorbent was characterized using elemental analysis, FTIR, SEM and EDAX analysis. The adsorption studies were conducted in batch mode. The effects of pH, contact time, the concentration of metals and the regeneration efficiency were studied. The removal of Ni2+, Cd2+, PO4 3- and NO3 - was not pH dependent. The maximum removal capacities of the CHA/MFC adsorbent for Ni2+, Cd2+, PO4 3- and NO3 - were 2.021, 1.224, 0.843 and 0.209mmol/g, respectively. The Langmuir and Sips models were representative to simulate adsorption isotherms. The results of adsorption kinetic indicate that adsorption was very fast for all studied compounds.

Consistency before Availability : Network Reference Point based Failure Detection for Controller Redundancy

Konferensbidrag (refereegranskat)abstract
- Distributed control systems constitute the automation solution backbone in domains where downtime is costly. Redundancy reduces the risk of faults leading to unplanned downtime. The Industry 4.0 appetite to utilize the device-to-cloud continuum increases the interest in network-based hardware-agnostic controller software. Functionality, such as controller redundancy, must adhere to the new ground rules of pure network dependency. In a standby controller redundancy, only one controller is the active primary. When the primary fails, the backup takes over. A typical network-based failure detection uses a cyclic message with a known interval, a.k.a. a heartbeat. Such a failure detection interprets heartbeat absences as a failure of the supervisee; consequently, a network partitioning could be indistinguishable from a node failure. Hence, in a network partitioning situation, a conventional heartbeat-based failure detection causes more than one active controller in the redundancy set, resulting in inconsistent outputs. We present a failure detection algorithm that uses network reference points to prevent network partitioning from leading to dual primary controllers. In other words, a failure detection that prioritizes consistency before availability.
