- The Swedish National Graduate School for Digital Technologies in Education (GRADE) is a cooperative venture between six Swedish universities established during 2018. Within the field of educational sciences and in the area of digital technologies in education, GRADE aims to strengthen the expertise in the area and to increase national and international cooperation in research training activities.Over a number of years, and from multitude of sources (cf. Brown & Davis, 2004; Fisher, Higgins & Loveless, 2006; Kafai & Resnick 1996), research has stressed that increased digitalization in schools leads to a complexity that needs to be taken into account on different levels, from different perspectives and with different designs, methodologies and theoretical perspectives (cf. Olofsson, Lindberg, Fransson & Hauge, 2015; Price, Jewitt & Brown, 2013; Tondeur, Valcke & van Braak, 2008). At a micro-level, the learning situation of students, teachers and school-leaders changes and it becomes important to deepen the knowledge about the impact digital technologies has on the fundamental conditions for teaching and learning of different school subjects (cf. Chun, Kern & Smith 2016; Leung & Baccaglini-Frank, 2017). On a macro-level, conditions for education as such changes and digital technologies becomes an important object of study as agents of change (Wong & Li, 2008). The digitalization of K-12 schools has long been highlighted in policy as a necessity (cf. Kirkman et al, 2002; OECD, 2010). However, research and evaluations (cf. Fransson et al, 2012; OECD, 2015; Wastiau et al, 2013) show that many substantial challenges remain. One of the fundamental pillars of GRADE is the interdisciplinary approach. Several disciplines are present (Applied IT, Curriculum studies, Education, Informatics, Technology and Learning, Educational work, Work-interated Learning) in researching digital technologies in K-12 schools with the ambition to contribute to the continued implementation, integration and use of digital technologies in Swedish K-12 schools that stems from the evidence-based knowledge produced within the activities of GRADE. The research within GRADE will be characterized by close cooperation with stakeholders from school practice, with the aim to contribute to concrete school development. In GRADE, a multi-level approach that involves multiple layers or levels of school activities will be encouraged. When possible, studies will be longitudinal. This will imply studies from an organizational and management perspective, e.g. studies of school leaders and other members of senior management positions responsible for digital technology use and implementation. Also implied are studies of teachers' teaching practices and didactical considerations, as well as studies of the students in classrooms and their learning using digital technologies. This will also imply that several issues with a bearing on the digitalization of education, for example regarding school policy, teaching, learning, assessment and professional development will be researched from different perspectives and with different methodological approaches. In this paper, these points of departure will be explored based on the expectations and experiences of the first twelve admitted doctoral students and their supervisors.

- Whiteness is a commercially important characteristic of paper and board, although its perception depends on many factors that often are neglected by instrumental measurements. High whiteness improves the contrast of printed areas and increases the number of reproducible colours, but few quantitative studies have been published. In this paper, we report just-noticeable image quality difference (JND) from pair wise comparisons of images printed on paper substrate of different shades and whiteness. The JND was estimated to approximately 15 CIE whiteness, for the images and whiteness levels in this study, implying that a large substrate whiteness difference is required to get a significant visual impact on image quality. Unlike previous studies limited to colour rendering issues, the influence of the substrate’s shade as a surrounding frame to the images was also investigated here. It was found that the surrounding frame did not have a significant impact on image quality, when the images had an inherent dim background around the objects in the image. However, floating images in which the image objects are adjacent to the unprinted substrate would need further attention, since their perceived image quality seemed to depend both on the colour reproduction related to whiteness and shade, and on the contrast between the image and the substrate.

- Managing inventories so that overall costs are kept low, while service levels are maintained is the central issue of inventory control, which only regulates two things: the size and the timing of orders. This is typically executed through a planning method, such as the reorder point system or, less frequently, the periodic order quantity system. These take into account a forecast, supposed to gauge the average future demand, and a predetermined safety stock, buffering against forecast errors and demand uncertainty. Pure demand also influences the system, as transactions affect the inventory level. It is crucial to understand how a complete system of demand, forecasts, safety stock calculations and planning methods work together to measure service level and overall cost of the system. This paper outlines a framework for the unambiguous representation of the relations between methods that interpret environmental parameters to plan orders. A number of simulations based on the framework are run to show, how the integration of the inventory control functions may affect the overall performance of the system. The usefullness of the framework lies in its ability to make a system duplicable (i.e. to transfer an inventory control system to a simulation model, or vice versa). Not only is this property important for creating simulation models that exactly depict the system being analysed, it also enables the study of a complete system for order planning, as opposed to optimising individual methods. Studying an inclusive system allow the same metrics to be used to evaluate changes to any method in the system. Another benefit of this approach is that the system's metrics directly reflect changes in the environment. Simulations based on this framework are precise and substantially easier to evaluate than models not adhering to any standard.

- Supply Chain Management (SCM) is becoming increasingly complex and an intensified competition in the end-markets has started to create a situation where co-operation requirements between companies in a Supply Chain (SC) are increasing. The old mechanistic operations management solutions are becoming obsolete and advanced decision support is increasingly needed to realize efficient and effective management of complex SCs. The objective of this research is to contribute to the understanding of how Agent Based Modeling (ABM) can advance decision making and to discuss why ABM should be regarded as method to realize Information Fusion (IF). In this research work an agent based model of SCM has been implemented in a simulation platform to provide an approach for evaluation of decision and management alternatives. Research shows that this kind of decision support system is based on IF, since it collects and fuses information from different sources into a situation image that provides effective support for human decision making

Extern granskning av utbildningsprogram – erfarenheter från två lärosäten.
- 2019
-
Konferensbidrag (refereegranskat)abstract
- Svenska lärosäten har utvecklat egna kvalitetssystem som ska granskas och godkännas av universitetskans-lersämbetet (UKÄ). Typiskt bygger lärosätenas kvalitetssäkrings-system på cykliska mäta-värdera-åtgärda aktiviteter. I flera av dessa system förekommer extern kollegial granskning som en viktig komponent. Syftet med detta arbete är att belysa två olika system för extern kollegial granskning från olika perspektiv. Den externa granskningen av högskoleingenjörsprogrammen i maskinteknik vid Uppsala universitet och Umeå universitet är utgångspunkten och de perspektiv som belyses är de från• Programansvariga,• Utbildningsledare på fakultetsnivå, samt• Extern granskareI arbetet teoretiseras inte upplägg och genomförande av kvalitetsarbetet eller den kollegiala granskningen, utan målet är att genom vittnesbörd sprida praktisk kunskap och erfarenheter om två olika system för extern kollegial granskning.Initialt beskrivs de två olika systemen, hur olika aktiviteter och processer är tänkt att tillsammans bidra till att säkerställa att utbildningar håller en hög kvalitet. Särskilt fokus läggs på att beskriva upplägget på den externa kollegiala granskningen och hur den information som granskningen ger vid handen återkopplas till program och andra intressenter. Fakultetens utbildningsledare ger sin syn på genomförandet av den kollegiala granskningen ur ett övergripande fakultetsperspektiv samt beskriver de fakultetsövergripande slutsatser som dragits utifrån de externa granskningarna. Programansvariga beskriver verksamhetsnära erfarenheter av de kollegiala granskningarna. Särskilt intressant är beskrivningen av hur utfallet av den kollegiala granskningen bidragit till att definiera utvecklingsprojekt på programnivå. Resultatet kopplas till resursåtgång.Det tredje perspektivet är det av den externe granskaren. I fallet med högskoleingenjörsprogrammet i maskinteknik vid Uppsala respektive Umeå universitet var det samma granskare vilket ger en unik möjlighet att få en extern parts synpunkter på underlag i förhållande till efterfrågad granskning.Slutligen sammanfattas styrkor och svagheter i de båda ansatserna till extern kollegial granskning.
