Boende för äldre: En studie av 10 kommuner
- 2015
-
Reports (other academic/artistic)abstract
- Andelen äldre personer i det svenska samhället ökar. I Sverige finns boendeformer som på olika sätt är anpassade efter äldres behov. Hur utbudet av dessa för äldre individer anpassade boendeformer ser ut och vilken information kommuner ger till äldre kan ses som viktiga för att förstå om äldre väljer att bo kvar eller flytta. I denna rapport kartläggs hur nuvarande utbud av de tre boendeformerna vård- och omsorgsboende, trygghetsbostäder och seniorbostäder ser ut på bostadsmarknaden vad gäller den äldre befolkningen i tio utvalda kommuner. I rapporten ligger tonvikten på kommunala företrädares uppfattningar och på kommunernas planer. För att få en större förståelse görs jämförelser med siffror från samtliga kommuner hämtade från Boverkets Bostadsmarknadsenkät (2014). Denna rapport är den första delen av en större studie som syftar till att undersöka push- och pullfaktorer som påverkar äldres val av boende. Av kartläggningen framgår att bostadsutbudet i de olika kommunerna skiljer sig åt, där vissa har bostadsöverskott medan andra har bostadsunderskott men där majoriteten av kommunerna erbjuder de tre olika boendeformerna. I storstadsregionen och i de större städerna finns ett utbud av samtliga tre boendeformer medan flera av glesbygdskommunerna saknar trygghetsbostäder. Rådgivning i de flesta kommuner är reaktiv snarare än proaktiv. I rapporten väcks frågan om hur vi ska se på boendet för de äldsta.

Conference paper (peer-reviewed)abstract
- 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.

Critical Imaginaries and Reflections on Artificial Intelligence and Robots in Postdigital K-12 Education
- 2019

Journal article (peer-reviewed)abstract
- It is commonly suggested that emerging technologies will revolutionize education. In this paper, two such emerging technologies, artificial intelligence (AI) and educational robots (ER), are in focus. The aim of the paper is to explore how teachers, researchers and pedagogical developers critically imagine and reflect upon how AI and robots could be used in education. The empirical data were collected from discussion groups that were part of a symposium. For both AI and ERs, the need for more knowledge about these technologies, how they could preferably be used, and how the emergence of these technologies might affect the role of the teacher and the relationship between teachers and students, were outlined. Many participants saw more potential to use AI for individualization as compared with ERs. However, there were also more concerns, such as ethical issues and economic interests, when discussing AI. While the researchers/developers to a greater extent imagined ideal future technology-rich educational practices, the practitioners were more focused on imaginaries grounded in current practice.

Journal article (peer-reviewed)abstract
- Accurate determination of the size of nanoparticles has an important role in many different scientific and industrial purposes, such as in material, medical and environment sciences, colloidal chemistry and astrophysics. We describe an effective optical method to determine the size of nanoparticles by analysis of transmission and scattering of visible spectral range data from a designed UV-Vis multi-spectrophotometer. The size of the nanoparticles was calculated from the extinction cross section of the particles using Rayleigh approximation and Mie theory. We validated the method using polystyrene nanospheres, cellulose nanofibrils, and cellulose nanocrystals. A good agreement was achieved through graphical analysis between measured extinction cross section values and theoretical Rayleigh approximation and Mie theory predictions for the sizes of polystyrene nanospheres at wavelength range 450-750 nm. Provided that Rayleigh approximation's forward scattering (FS)/back scattering (BS) ratio was smaller than 1.3 and Mie theory's FS/BS ratio was smaller than 1.8. A good fit for the hydrodynamic diameter of nanocellulose was achieved using the Mie theory and Rayleigh approximation. However, due to the high aspect ratio of nanocellulose, the obtained results do not directly reflect the actual cross-sectional diameters of the nanocellulose. Overall, the method is a fast, relatively easy, and simple technique to determine the size of a particle by a spectrophotometer. Consequently, the method can be utilized for example in production and quality control purposes as well as for research and development applications.

Conference paper (peer-reviewed)abstract
- In attempting to address real-life decision problems, where uncertainty about input data prevails, some kind of representation of imprecise information is important and several have been proposed over the years. In particular, first-order representations of imprecision, such as sets of probability measures, upper and lower probabilities, and interval probabilities and utilities of various kinds, have been suggested for enabling a better representation of the input sentences. A common problem is, however, that pure interval analyses in many cases cannot discriminate sufficiently between the various strategies under consideration, which, needless to say, is a substantial problem in real-life decision making in agents as well as decision support tools. This is one reason prohibiting a more wide-spread use. In this article we demonstrate that in many situations, the discrimination can be made much clearer by using information inherent in the decision structure. It is discussed using second-order probabilities which, even when they are implicit, add information when handling aggregations of imprecise representations, as is the case in decision trees and probabilistic networks. The important conclusion is that since structure carries information, the structure of the decision problem influences evaluations of all interval representations and is quantifiable.

Journal article (peer-reviewed)abstract
- In real-life decision analysis, the probabilities and utilities of consequences are in general vague and imprecise. One way to model imprecise probabilities is to represent a probability with the interval between the lowest possible and the highest possible probability, respectively. However, there are disadvantages with this approach; one being that when an event has several possible outcomes, the distributions of belief in the different probabilities are heavily concentrated toward their centres of mass, meaning that much of the information of the original intervals are lost. Representing an imprecise probability with the distribution’s centre of mass therefore in practice gives much the same result as using an interval, but a single number instead of an interval is computationally easier and avoids problems such as overlapping intervals. We demonstrate why second-order calculations add information when handling imprecise representations, as is the case of decision trees or probabilistic networks. We suggest a measure of belief density for such intervals. We also discuss properties applicable to general distributions. The results herein apply also to approaches which do not explicitly deal with second-order distributions, instead using only first-order concepts such as upper and lower bounds.
