- The87Sr/86Sr isotope ratio has been widely used as aphysical tool to date and correlate carbonate successions due to the long Srresidence time in comparison with the ocean mixing time. If this method workson oceanic successions, marginal basins may show different Sr isotope recordsin comparison with the coeval ocean one due to sea-level variations,continental run-off and restricted water exchanges. In this work, we present the87Sr/86Sr isotope record of the upper Miocene carbonateramp of the Lithothamnion Limestone(Majella Mountain, central Apennines), as an example of the onset of restrictedwater exchanges between a marginal basin and the ocean water masses. The overalllatemost Tortonian–earlyMessinian Sr isotope record of the Lithothamnion Limestonefits below the global reference line. This deviation has been interpreted as dueto the strong control that freshwater input and enhanced continental run-off,linked to the migration of the Apennine accretionary wedge and foredeep system,have had on the central Adriatic water chemistry. These results imply that anaccurate oceanographic and geodynamic framework along with diagenetic overprintinvestigation has to be taken into consideration prior to apply SIS oncarbonate successions on marginal basins, even when facies analyses indicatefully marine conditions. This seems to be the case for the upper MioceneCentral Mediterranean carbonate successions, but may have more general validityand be extended to other recent or past marginal basins.

Quality control in cone-beam computed tomography (CBCT): EFOMP-ESTRO-IAEA protocol
- 2017
-
Rapport (refereegranskat)abstract
- Quality control of cone-beam computed tomography (CBCT) systems is an essential part of quality assurance to periodically check that quality requirements are met, reduce uncertainties and errors and reduce the likelihood of accidents and incidents. Radiation exposure levels must be measured to ensure that patient doses associated with CBCT examinations are kept as low as reasonably achievable consistent with the required diagnostic information. The main purpose of this document is to present procedures for quality control of CBCT systems used for dental, radiotherapy, interventional radiology and guided surgery applications.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the guideline presented in this article is to unify the test parameters for image quality evaluation and radiation output in all types of cone-beam computed tomography (CBCT) systems. The applications of CBCT spread over dental and interventional radiology, guided surgery and radiotherapy. The chosen tests provide the means to objectively evaluate the performance and monitor the constancy of the imaging chain. Experience from all involved associations has been collected to achieve a consensus that is rigorous and helpful for the practice. The guideline recommends to assess image quality in terms of uniformity, geometrical precision, voxel density values (or Hounsfield units where available), noise, low contrast resolution and spatial resolution measurements. These tests usually require the use of a phantom and evaluation software. Radiation output can be determined with a kerma-area product meter attached to the tube case. Alternatively, a solid state dosimeter attached to the flat panel and a simple geometric relationship can be used to calculate the dose to the isocentre. Summary tables including action levels and recommended frequencies for each test, as well as relevant references, are provided. If the radiation output or image quality deviates from expected values, or exceeds documented action levels for a given system, a more in depth system analysis (using conventional tests) and corrective maintenance work may be required.

Quality control for cone beam CT devices: The EFOMP guidelines for assessing image quality and dose
- 2016
-
Ingår i: ECR 2016.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Learning objectives: Learn about an objective, practical and unifying methodology for quality control of all cone beam CT (CBCT) modalities. Understand the choice and justification of the proposed tests Learn how to perform the tests on a routine basis.Background: Current guidelines for quality control of CBCT devices consider the available applications (dental, radiotherapy, interventional radiology and guided surgery) as different entities [1], [2]. However, the data acquisition and reconstruction methods are similar. Henceforth, the evaluation parameters for image quality and dose can be unified.Findings and procedure details: The parameters used for image quality assessment are uniformity, accuracy of density values (or Hounsfield units where appropriate), geometrical evaluation, noise, low-contrast resolution (including contrast-to-noise ratio) and high-contrast resolution. Detailed procedures using free software and commercially available test phantoms are described in the guidelines, which are currently under external review.Conclusion: These guidelines include the minimum tests that should be performed to ensure reliable, safe and consistent performance of CBCT devices. This minimum has been sought to guarantee compatibility with all manufacturers, all cone beam modalities and existing national and international documents.

Tidskriftsartikel (refereegranskat)abstract
- Greening cities, namely installing new parks, rooftop gardens or planting trees along the streets, undoubtedly contributes to an increase in wellbeing and enhances the attractiveness of open spaces in cities. At the same time, we observe an increasing use of greening strategies as ingredients of urban renewal, upgrading and urban revitalization as primarily market-driven endeavours targeting middle class and higher income groups sometimes at the expense of less privileged residents. This paper reflects on the current debate of the social effects of greening using selected examples. We discuss what tradeoffs between social and ecological developments in cities mean for the future debate on greening cities and a socially balanced and inclusive way of developing our cities for various groups of urban dwellers. We conclude that current and future functions and features of greening cities have to be discussed more critically including a greater awareness of social impacts.

Tidskriftsartikel (refereegranskat)abstract
- We present Nemo-Nordic, a Baltic and North Sea model based on the NEMO ocean engine. Surrounded by highly industrialized countries, the Baltic and North seas and their assets associated with shipping, fishing and tourism are vulnerable to anthropogenic pressure and climate change. Ocean models providing reliable forecasts and enabling climatic studies are important tools for the shipping infrastructure and to get a better understanding of the effects of climate change on the marine ecosystems. Nemo-Nordic is intended to be a tool for both short-term and long-term simulations and to be used for ocean forecasting as well as process and climatic studies. Here, the scientific and technical choices within Nemo-Nordic are introduced, and the reasons behind the design of the model and its domain and the inclusion of the two seas are explained. The model's ability to represent barotropic and baroclinic dynamics, as well as the vertical structure of the water column, is presented. Biases are shown and discussed. The short-term capabilities of the model are presented, especially its capabilities to represent sea level on an hourly timescale with a high degree of accuracy. We also show that the model can represent longer timescales, with a focus on the major Baltic inflows and the variability in deep-water salinity in the Baltic Sea.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper takes its departure from an investigation of Sexual and Reproductive Health and Rights, SRHR, in teacher education programs throughout Sweden in 2016. It was a research mission from the Public Health Agency of Sweden. A survey of 875 syllabuses from all universities in Sweden was analysed through methods of qualitative textual analysis. The aim was to explore if and in which subject syllabuses SRHR as a knowledge area was visible. The theory behind is that syllabuses are composed according to the theory of constructive alignment. The result shows major differences between various universities regarding the field of knowledge of SRHR in different syllabuses, as well as in different educational programmes and levels. In the quantitative part graphs show a cluster of indicators with a high number of occurrences in the syllabuses. Some of these indicators are; ethics, gender, democracy, norms, norm criticism and core values, convention on the rights of the child, human rights, discrimination and offensive treatment. During the autumn in 2017 a social movement called #metoo, with subgroups, has gotten worldwide attention and has had a great impact in Sweden regarding sexual abuse. In connection to this, demands have been raised that sexuality and relation education must much more visible in compulsory school as well as in teacher education. It is clear that the #metoo movement has contributed to ongoing debate regarding the knowledge area SRHR. We will discuss the controversial issues connected to identity and values among engaged citizens thus touch on the relation between formal and informal learning in connection to the importance of media in citizenship education. KW: identity, compulsory school, SRHR, teacher education, #metoo

Nationalism i fredens tjänst : Svenska skolornas fredsförening, fredsfostran och historieundervisning 1919-1939
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis is to contribute to the field of research that examines the relationship between peace efforts and nationalism. The relationship will be studied from perspectives of educa- tional history and history didactics. More precisely, by focusing on history education, this disserta- tion will analyse the demands for a comprehensive peace education in schools that were put forward by a long list of actors in the Western world during the interwar period, and as such discuss to what extent, and in what ways, nationalism influenced the content and design of this peace education. The main theoretical framework of this thesis is the concept of nationalism, and the position of nationalism as a hegemonic ideology during the first half of the 20th century. Another central un- derstanding is the assumption that the educational system, specifically history education, played a central role in creating, maintaining and strengthening collective identities as well as the prevailing ideological hegemony. The empirical investigation has been limited to studying the demands and ideas presented by Nordic peace educators, mainly The Swedish School Peace League (SSF), regar- ding peace-educating history teaching. As such, the empirical aim has been to investigate the SSF’s views on the relationship between nationalism and peace education, i.e., how internationalism and pacifism were to be taught, as well as how this understanding affected the League’s ideas regarding history teaching. The results have also been analysed from a gender perspective, based on the as- sumption that contemporary notions of gender in relation to nationalism, war and peace in different ways had an impact upon the content and format of the proposed peace education. The study shows that the SSF regarded nationalism as the very foundation and prerequisite for any peace education. SSF thus tried to reconcile nationalism, internationalism and pacifism under one and the same ideological approach; “patriotic pacifism”, which in turn strongly influenced the endorsed peace-educating history teaching. Furthermore, the study highlights boys’ central role in the peace education project, which essentially set the long-term goal of creating a new pacifist and internationally oriented male ideal and yet, despite these aims, continued an intimate association with the “national”. Key concepts in SSF’s peace education were unite and supplement, and thereby they redefined central meanings of hegemonic nationalism. SSF’s patriotic pacifism and its impact on the association's demands for a peace-educating history teaching can best be described as an “intra-hegemonic counterforce”.

Tidskriftsartikel (refereegranskat)abstract
- Background: Studies of related individuals have consistently demonstrated notable familial aggregation of cancer. We aim to estimate the heritability and genetic correlation attributable to the additive effects of common single-nucleotide polymorphisms (SNPs) for cancer at 13 anatomical sites. Methods: Between 2007 and 2014, the US National Cancer Institute has generated data from genome-wide association studies (GWAS) for 49 492 cancer case patients and 34 131 control patients. We apply novel mixed model methodology (GCTA) to this GWAS data to estimate the heritability of individual cancers, as well as the proportion of heritability attributable to cigarette smoking in smoking-related cancers, and the genetic correlation between pairs of cancers. Results: GWAS heritability was statistically significant at nearly all sites, with the estimates of array-based heritability, h(l)(2), on the liability threshold (LT) scale ranging from 0.05 to 0.38. Estimating the combined heritability of multiple smoking characteristics, we calculate that at least 24% (95% confidence interval [CI] = 14% to 37%) and 7% (95% CI = 4% to 11%) of the heritability for lung and bladder cancer, respectively, can be attributed to genetic determinants of smoking. Most pairs of cancers studied did not show evidence of strong genetic correlation. We found only four pairs of cancers with marginally statistically significant correlations, specifically kidney and testes (rho = 0.73, SE = 0.28), diffuse large B-cell lymphoma (DLBCL) and pediatric osteosarcoma (rho = 0.53, SE = 0.21), DLBCL and chronic lymphocytic leukemia (CLL) (rho = 0.51, SE = 0.18), and bladder and lung (rho = 0.35, SE = 0.14). Correlation analysis also indicates that the genetic architecture of lung cancer differs between a smoking population of European ancestry and a nonsmoking Asian population, allowing for the possibility that the genetic etiology for the same disease can vary by population and environmental exposures. Conclusion: Our results provide important insights into the genetic architecture of cancers and suggest new avenues for investigation.

Rätt att bo kvar : en handbok i organisering mot hyreshöjningar och gentrifiering
- 2016
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Det här är en handbok som skrivits för att användas praktiskt i kampen om hyresrättens framtid. Boken har växt fram ur gemensamma erfarenheter av att ta strid mot renoveringar med höga hyreshöjningar som följd. Det har gett oss både kunskaper om lokal organisering och en övertygelse om vikten av att hyresgäster ska ha rätt till att påverka framtiden i de bostadsområden de bor i. De senaste åren har vi kunnat se hur hyreslägenheter renoveras med omfattande hyreshöjningar som följd. Konsekvenserna har blivit att många hyresgäster har tvingats flytta, ibland från bostadsområden de bott i under lång tid, då de inte längre har råd att betala hyran. Om inte hyresgäster går samman och kräver sina rättigheter kommer inget förändras och flera tusentals människor tvingas flytta. Den här handboken ska användas som ett praktiskt verktyg för lokal organisering. Vi som har gjort den här boken är engagerade i olika rörelser, några av oss är också forskare med inriktning mot bostad- spolitik och stadsutveckling. Boken har tillkommit genom en kollektiv process, där många varit inblandade för att bidra med sina erfarenheter och perspektiv. En lista med alla medverkande inklusive de rörelser som står bakom den här boken finns lägst bak.
