Journal article (peer-reviewed)abstract
- Background: Previous research on associations between cardiovascular health, measured at a single timepoint, and rate of age-related cognitive decline shows divergent findings dependent on the participants’ age and the health metric studied. The aim of this study was to add to the knowledge in this field by investigating whether change in cardiovascular health, assessed with Life’s Simple 7 (LS7) score, is associated with rate of cognitive change in young-old and old-old adults. Methods: The study included 1022 participants aged ≥ 60 years from the Swedish National Study on Aging and Care-Kungsholmen (SNAC-K), who underwent repeated neuropsychological testing (episodic memory, semantic memory, verbal fluency, and perceptual speed) across up to 15 years. LS7, composed of seven cardiovascular health metrics (smoking, diet, physical activity, body mass index, plasma glucose, total serum cholesterol, and blood pressure), was assessed at baseline and at the 6-year follow-up. Change in LS7 was calculated as the difference between baseline and 6 years (range − 5 to 8 points) and categorised into worse (−5 to −2 points), stable (−1 to 1 points), and improved (2 to 8 points). Change in cognitive performance as a function of LS7 change categories was estimated using linear mixed-effects models. Results: Participants were classified as stable (67.1%), improved (21.0%), or worse (11.8%) according to changes in LS7 score. Both the worse and improved categories were associated with faster cognitive decline. Age-stratified analyses revealed that worsening of LS7 was clearly associated with faster cognitive decline in the old-old (≥ 78 years), whereas improvement tended be associated with faster cognitive decline in the young-old (< 78 years) group. Conclusions: Change in cardiovascular health in old age may lead to accelerated cognitive decline, particularly in late senescence. These results suggest that it is important to monitor and maintain cardiovascular health status in very old adults.

Programming in Primary School: Towards a Research-Based Assessment Instrument
- 2018

Conference paper (peer-reviewed)abstract
- In March 2017, the Swedish government decided to introduce digital competence - including programming - in primary school. As a consequence, every math and technology teacher in grades 1-9 in Sweden is expected to integrate programming in their teaching. Furthermore, the Swedish school law requires that teaching is based on scientific evidence and proven experience. In addition to professional development for teachers, it is hence crucial to also conduct research on different aspects of programming in the classroom. In this paper, we describe the process of developing a scientifically grounded instrument for assessing students' programming skills, as part of a longitudinal research project investigating how students in primary school learn programming. We also present the main findings related to the suitability of the instrument based on a pilot study conducted in spring 2019, collecting data from 310 students.

Representational and Territorial Economies in Global Citizenship Education : Welcoming the Other at the Limit of Cosmopolitan Hospitality
- 2013
-
In: Social Theory and Education Research Volume II. - : Sage Publications. - 9781446253120
-
Book chapter (peer-reviewed)abstract
- In this article, I argue that any success a discourse on cosmopolitan hospitality might have in global citizenship education depends on how it deals with its own limits, and I propose a way of responding to these limits that takes the cosmopolitan commitment to openness to the other seriously. Following Jacques Derrida, my point is that to teach global citizenship on the basis that we already can know who the other is risks counting some persons ‘in’ while leaving others ‘out’, which forecloses the possibility of welcoming something new and unforeseen at the limit of our cosmopolitan selves.

Pollution by hexachlorobenzene and pentachlorophenol in the coastal plain of Sao Paulo state, Brazil

Journal article (peer-reviewed)abstract
- Organochlorine compounds were dumped by chemical industries during the 1970s in many areas of the coastal plain of Sao Paulo state in Brazil. These dumps, located on hillsides and in valleys, in both rural and urban environments, are responsible for soil and water pollution. The objective of this work was to determine how the pollutants have spread in an area occupied by a spodosol-type soil mantle. The study combines soil morphological observations with soil and water analysis of hexachlorobenzene (HCB) and pentachlorophenol (PCP) in soil toposequences. The results indicate that the highest pollutant concentrations are observed near the dump site and that the compounds contamination is increasing. A map integrating topography and chemical concentrations was created to visualize the spatial distribution of HCB levels in the landscape. Physical and chemical analyses were performed to measure HCB and PCP levels in the soil. Soil water appears to act as a vector of HCB, probably through complexation with and dispersal of dissolved organic matter. The persistence of HCB at the studied site is most likely due to the low pH values in combination with a high content of organic matter. HCB was consistently found in higher concentrations than PCP. It is plausible that the cause of this difference is that PCP is degraded more easily under sunlight than HCB and that degradation of PCP under acid conditions leads to the formation of HCB.
