    Metal catalyzed formation of chlorinated aromatic compounds: a study of the correlation pattern in incinerator fly ash.2007In: Chemosphere, ISSN 0045-6535, E-ISSN 1879-1298, Vol. 67, no 9, p. S185-S190Article in journal (Refereed)
    Abstract [en]

    Chlorinated aromatics are unintentionally formed and released from combustion and other thermal processes involving organic matter and chlorine. The catalytic activity of incinerator fly ash in the low-temperature formation of chlorinated aromatics has been demonstrated in both laboratory experiments and full-scale trials. Copper has been shown to be an effective catalyst, but several other transition metals possess a similar activity. Here results are reported from a series of full-scale combustion trials with different fractions of household and industrial wastes, with waste from forestry as a reference fuel. The composition of elements and chlorinated aromatics in the fly ash was evaluated with principal component analysis and partial least squares regression. The observed correlation pattern indicates that metals other than copper are of equal importance for the catalytic activity. Chromium and nickel are two of these metals, which may contribute to the de novo formation of chlorinated benzenes, phenols, PCDD and PCDF.

    The correlation pattern of fly ash components: Chromium as a potential catalyst in the thermal formation of chlorinated aromatic compounds2004In: Environmental Chemistry, ISSN 1448-2517, E-ISSN 1449-8979, Vol. 1, no 1, p. 18-21Article in journal (Refereed)
    Abstract [en]

    Chlorinated aromatic compounds are unintentionally released from combustion sources into the environment. This thermal formation is catalyzed by fly ash components and much interest has been focussed on the role of copper. This study report results from a series of 16 full-scale trials with different fuel compositions. The correlation pattern of fly ash components seem to suggest that the catalytic effect may be due also to other metal oxychlorination catalysts. Chromium shows particularly strong and statistically significant correlations with many of the chlorinated phenols, benzenes, dibenzo-p-dioxins (PCDDs), and dibenzofurans (PCDFs).

    Poly-substance use and antisocial personality traits at admission predict cumulative retention in a buprenorphine programme with mandatory work and high compliance profile2011In: BMC Psychiatry, ISSN 1471-244X, E-ISSN 1471-244X, Vol. 11, p. Article ID: 81-Article, review/survey (Refereed)
    Abstract [en]

    Background

    Continuous abstinence and retention in treatment for alcohol and drug use disorders are central challenges for the treatment providers. The literature has failed to show consistent, strong predictors of retention. Predictors and treatment structure may differ across treatment modalities. In this study the structure was reinforced by the addition of supervised urine samples three times a week and mandatory daily work/structured education activities as a prerequisite of inclusion in the program.

    Methods

    Of 128 patients consecutively admitted to buprenorphine maintenance treatment five patients dropped out within the first week. Of the remaining 123 demographic data and psychiatric assessment were used to predict involuntary discharge from treatment and corresponding cumulative abstinence probability. All subjects were administered the Structured Clinical Interview for DSM-IV-TR, and the Symptom Checklist 90 (SCL-90), the Alcohol Use Disorder Identification Test (AUDIT), the Swedish universities Scales of Personality (SSP) and the Sense of Coherence Scale (SOC), all self-report measures. Some measures were repeated every third month in addition to interviews.

    Results

    Of 123 patients admitted, 86 (70%) remained in treatment after six months and 61 (50%) remained in treatment after 12 months. Of those discharged involuntarily, 34/62 individuals were readmitted after a suspension period of three months. Younger age at intake, poly-substance abuse at intake (number of drugs in urine), and number of conduct disorder criteria on the SCID Screen were independently associated with an increased risk of involuntary discharge. There were no significant differences between dropouts and completers on SCL-90, SSP, SOC or AUDIT.

    Conclusion

    Of the patients admitted to the programme 50% stayed for the first 12 months with continuous abstinence and daily work. Poly-substance use before intake into treatment, high levels of conduct disorder on SCID screen and younger age at intake had a negative impact on retention and abstinence.

    Improving interoperability in ePrescribing2012In: Interactive Journal of Medical Research, E-ISSN 1929-073X, Vol. 1, no 2, article id e17Article in journal (Refereed)
    Abstract [en]

    Background: The increased application of eServices in health care, in general, and ePrescribing (electronic prescribing) in particular, have brought quality and interoperability to the forefront. The application of standards has been put forward as one important factor in improving interoperability. However, less focus has been placed on other factors, such as stakeholders’ involvement and the measurement of interoperability. An information system (IS) can be regarded to comprise an instrument for technology-mediated work communication. In this study, interoperability refers to the interoperation in the ePrescribing process, involving people, systems, procedures and organizations. We have focused on the quality of the ePrescription message as one component of the interoperation in the ePrescribing process.

    Objective: The objective was to analyze how combined efforts in improving interoperability with the introduction of the new national ePrescription format (NEF) have impacted interoperability in the ePrescribing process in Sweden, with the focus on the quality of the ePrescription message.

    Methods: Consecutive sampling of electronic prescriptions in Sweden before and after the introduction of NEF was undertaken in April 2008 (pre-NEF) and April 2009 (post-NEF). Interoperability problems were identified and classified based on message format specifications and prescription rules.

    Results: The introduction of NEF improved the interoperability of ePrescriptions substantially. In the pre-NEF sample, a total of 98.6% of the prescriptions had errors. In the post-NEF sample, only 0.9% of the prescriptions had errors. The mean number of errors was fewer for the erroneous prescriptions: 4.8 in pre-NEF compared to 1.0 in post-NEF.

    Conclusions: We conclude that a systematic comprehensive work on interoperability, covering technical, semantical, professional, judicial and process aspects, involving the stakeholders, resulted in an improved interoperability of ePrescriptions.

    Folate bioavailability from breads and a meal assessed with a human stable-isotope area under the curve and ileostomy model.2010In: American Journal of Clinical Nutrition, ISSN 0002-9165, E-ISSN 1938-3207, Vol. 92, no 3, p. 532-538Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Recent data revealed differences in human absorption kinetics and metabolism between food folates and folic acid supplements and fortificant.

    OBJECTIVE: The objective was to determine folate bioavailability after ingestion of breads or a breakfast meal fortified with either 5-CH(3)-H(4) folate or folic acid by using a stable-isotope area under the curve (AUC) and ileostomy model.

    DESIGN: In a randomized crossover trial, healthy ileostomists (n = 8) ingested single doses of whole-meal bread that contained ap 450 nmol (200 micro g) of either (6S)-[(13)C(5)]5-CH(3)-H(4) folate or [(13)C(5)]folic acid or a breakfast meal that contained ap 450 nmol (200 micro g) [(13)C(5)]folic acid. We collected blood from the subjects during 12 h postdose for assessment of plasma kinetics. Nonabsorbed folate was assessed from labeled folate contents in stomal effluent 12 and 24 h postdose.

    RESULTS: The median (range) plasma AUC(0 rarr 12) (AUC from 0 to 12 h after ingested dose) of 66 nmol sdot h/L (34-84 nmol sdot h/L) after ingestion of bread that contained (6S)-[(13)C(5)]5-CH(3)-H(4) folate was significantly greater (P lt 0.001) than that after ingestion of [(13)C(5)]folic acid in fortified bread [28 nmol sdot h/L (15-38 nmol sdot h/L)] and a fortified breakfast meal [26 nmol sdot h/L (15-60 nmol sdot h/L)]. Both labeled doses resulted in increases of plasma [(13)C(5)]5-CH(3)-H(4) folate. However, the kinetic variables C(max) (maximum plasma concentration) and T(max) [time (min) of maximum plasma concentration] varied after ingestion of the different folate forms. The stomal folate content was lt 10% of the ingested dose and did not vary significantly after ingestion of test foods that contained (6S)-[(13)C(5)]5-CH(3)-H(4) folate [median (range): 13 nmol (10-31 nmol)] or [(13)C(5)]folic acid [median (range): 25 nmol (8-42 nmol)] (P = 0.33).

    CONCLUSIONS: Our data confirm differences in plasma absorption kinetics for reduced folates and synthetic folic acid administered with the test foods. Stomal folate contents indicated almost complete bioavailability of labeled folate from the breads or breakfast meal.

    Effect of 2 pieces of nutritional advice on folate status in Swedish women: a randomized controlled trial.2009In: American Journal of Clinical Nutrition, ISSN 0002-9165, E-ISSN 1938-3207, Vol. 89, no 4, p. 1053-1058Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Ten years after the introduction of mandatory folic acid fortification in the United States, Canada, and Costa Rica, the issue is still under debate in several countries, and Sweden recently decided against mandatory fortification.

    OBJECTIVE: The objective was to determine the folate status of women after an intervention involving 2 Swedish dietary recommendations: a food recommendation (bread) and a complete meal recommendation (breakfast).

    DESIGN: Fifty-one free-living women with normal folate status participated in a 12-wk controlled intervention trial. Subjects were randomly assigned to one of the following interventions: apple juice (control group; n = 17), a breakfast providing 125 microg folate (breakfast group; n = 17), or 5 slices of whole-meal bread to be eaten over the course of the day, which provided 70 microg folate (bread group; n = 17). Folate status was assessed on the basis of concentrations of erythrocyte folate, serum folate, and plasma total homocysteine (tHcy) at baseline and at weeks 8 and 12 of the trial.

    RESULTS: In the breakfast group, initial median concentrations of erythrocyte folate (805 nmol/L) increased by 172 nmol/L (95% CI: 24, 293; P = 0.02) relative to the control. The relative increase in initial serum folate (2 nmol/L, 95% CI: 0, 5; P = 0.06) was nonsignificant. The initial tHcy concentration (8.7 micromol/L) decreased by 2.3 micromol/L (95% CI: -1, -3.4; P < 0.01). In the bread group, the initial tHcy concentration (9.1 micromol/L) decreased nonsignificantly by 1.4 micromol/L (95% CI: 0, -2.8; P = 0.08) relative to the control group, whereas other outcomes were stable.

    CONCLUSIONS: The folate status of the subjects improved after regular consumption of the breakfast meal. The additional folate intake from the bread maintained the folate status but was not sufficient to improve it.

    Human folate bioavailability2011In: Nutrients, ISSN 2072-6643, E-ISSN 2072-6643, Vol. 3, no 4, p. 475-490Article in journal (Refereed)
    Abstract [en]

    The vitamin folate is recognized as beneficial health-wise in the prevention of neural tube defects, anemia, cardiovascular diseases, poor cognitive performance, and some forms of cancer. However, suboptimal dietary folate intake has been reported in a number of countries. Several national health authorities have therefore introduced mandatory food fortification with synthetic folic acid, which is considered a convenient fortificant, being cost-efficient in production, more stable than natural food folate, and superior in terms of bioavailability and bioefficacy. Other countries have decided against fortification due to the ambiguous role of synthetic folic acid regarding promotion of subclinical cancers and other adverse health effects. This paper reviews recent studies on folate bioavailability after intervention with folate from food. Our conclusions were that limited folate bioavailability data are available for vegetables, fruits, cereal products, and fortified foods, and that it is difficult to evaluate the bioavailability of food folate or whether intervention with food folate improves folate status. We recommend revising the classical approach of using folic acid as a reference dose for estimating the plasma kinetics and relative bioavailability of food folate.

    Orange juice is a good folate source in respect to folate content and stability during storage and simulated digestion2008In: European Journal of Nutrition, ISSN 1436-6207, E-ISSN 1436-6215, Vol. 47, no 2, p. 92-98Article in journal (Refereed)
    Abstract [en]

    Background

    Estimated average folate intake in Sweden is less than 55% of the recommended daily intake (RDI) for women of childbearing age (Becker and Pearson in Riksmaten 1997–1998 Kostvanor och näringsintag i Sverige. National Food Administration, Uppsala, pp 34, 44, 121, 2002). Because a good folate status reduces the risk of neural tube defects, mandatory folic acid fortification is discussed in some European countries. This however, could lead to exposure to unintentionally high amounts of folic acid for some population groups, therefore targeted folic acid fortification could be an alternative.

    Aims

    To (1) determine natural folate content in three popular brands of orange juice sold in Sweden, (2) determine stability of natural folate and folic acid fortificant during shelf life in a folic acid/iron fortified orange juice, (3) determine folate stability in four juices during simulated household consumption for one week and (4) determine the in vitro bioaccessibility of natural folate in one brand of orange juice using the TNO gastroIntestinal Model (TIM).

    Methods

    Natural folate content in juices was determined using RP-HPLC-FL. To determine folic acid content and confirm RP-HPLC-FL values LCMS was used. Stability during shelf life was determined in unopened bottles of a folic acid/iron fortified juice and for one week in four popular juices under household consumption conditions with reopening of bottles daily. For an in vitro folate bioaccessibility experiment in orange juice the TNO TIM Model was used.

    Results

    5-CH3-H4folate was the dominant natural folate form in the juices with contents ranging from 16–30 µg/100 g. Shelf life losses of folic acid fortificant were 1–4%. During one week simulated household consumption 5-CH3-H4folate content decreased by up to 7% (n.s). Bioaccessibility of natural folate in orange juice was almost 100%. Most folate was released for absorption in jejunum between 60–120 min after trial start.

    Conclusion

    Orange juice may be considered a good source of natural folate in respect to content and stability during storage and simulated digestion. Moreover, added folic acid fortificant in a folic acid/iron fortified orange juice was stable during shelf life.

    Folates in bread: retention during bread-making and in vitro bioaccessibility2010In: European Journal of Nutrition, ISSN 1436-6207, E-ISSN 1436-6215, Vol. 49, no 6, p. 365-372Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Bread is an important folate source in several countries. However, bread-making was reported to cause losses of endogenous bread folates (approximately 40%) as well as added synthetic folic acid (approximately 30%). Furthermore, the bread matrix is suggested to inhibit absorption of folates.

    PURPOSE: To (1) estimate retention of both, endogenous folates and synthetic fortificants, during bread-making, (2) assess in vitro folate bioaccessibility from breads and a breakfast meal and (3) assess in vitro folate uptake.

    METHODS: Retention of folate forms was assessed by preparing fortified (folic acid and [6S]-5-CH(3)-H(4)folate) wholemeal breads and collect samples from dough, proofed dough and the bread. In vitro folate bioaccessibility was assessed using the TNO gastrointestinal model TIM. In vitro folate uptake was assessed using a novel Caco-2 cell/stable isotope model. Folate content in samples was measured using LCMS.

    RESULTS: Bread-making resulted in losses of 41% for endogenous folates and up to 25 and 65% for folic acid and [6S]-5-CH(3)-H(4)folate fortificant, respectively. 75% of endogenous bread folates and 94% of breakfast folates were bioaccessible as assessed by TIM. From [6S]-5-CH(3)-H(4)folate-fortified bread, relative folate uptake into Caco-2 cells was 71 +/- 11% (P < 0.05) when compared with a standard solution.

    CONCLUSION: Retention of folic acid fortificant during bread-making was substantially higher compared to retention of [6S]-5-CH(3)-H(4)folate fortificant. Data from the TIM and Caco-2 cell trials suggest an inhibiting effect of the tested bread matrices on in vitro bioaccessibility of folates, whereas folate bioaccessibility from a breakfast meal is almost complete.

    Chlorophyll a fluorescence an alternative method for estimating primary production1982In: Marine Biology, ISSN 1230-7688, Vol. 68, no 1, p. 71-75Article in journal (Refereed)
    Abstract [en]

    The in vivo chlorophyll a fluorescence index (F+DcM u-F-DcMu/F+DcMU) of natural waters was compared to the 14C-determined primary production, and the fluorescence intensity in the presence of 3-(3,4-dichlorophenyl)-l,l-dimethylurea (F + DCM~) was studied as a function of extracted and spectrophotometrically determined chlorophyll concentrations. Samples were taken every second week from May through October, 1979, at the station "Systrarna" situated in a coastal area of the Bottnian Sea. In addition, samples from the Archipelago Sea of the Baltic were collected on board the Finnish research vessel R/S "Aranda" during the September cruise 1979. The correlations between the fluorescence index and the 14C-determined primary production and between F+DcMu and total chlorophyll concentration were good when samples taken over short time intervals were compared. The shortcomings of both the fluorescence and the 14C methods are discussed. It is concluded that the fluorescence method is useful if it is desirable to follow with high time resolution any changes in the potential for photosynthesis (or pirmary production) in a water mass over relatively short time periods; e.g. during an algal bloom. The fluorescence method can furthermore be technically developed for automatic monitoring with a high time resolution. Efforts are being made in our laboratory to develop the method further to give information about the in situ rates of photosynthesis rather than the potential for photosynthesis in a phytoplankton population.

    Abstract [en]

    Teachers in Social Studies can benefit from geographical perspectives in their teaching of Social Studies in elementary and high school. The aim is to connect geographical perspectives to various social processes and to integrate it in teaching of Social Studies. But how can the relevance of geographical perspectives in an education for teachers in Social Studies be motivated and to what benefits can it be internalized? I will try to answer that question in this article. This relevance is mainly, with basis in a literature study, focused on democracy, sustainable development and digital literacy. It is also relevant by giving teachers a broader teaching skill and thus they are able to help pupils achieve higher-order skills.

    Geographical and Spatial Thinking in the Swedish Curriculum2017In: The Power of Geographical Thinking / [ed] Clare Brooks, Graham Butt, Mary Fargher, Springer, 2017, p. 137-150Chapter in book (Refereed)
    Abstract [en]

    This chapter concerns the views of knowledge adopted in the Swedish curriculum for state schools in an international context. It addresses how geographical and spatial thinking are expressed with regard to the subject specific abilities expected of students who learn geography. The introductory section highlights the current view of knowledge in the Swedish curriculum, explains how subject specific abilities for geography have been defined and used in the Swedish context, and describes their application in state schools. Importantly, these subject abilities are considered in relation to thinking both geographically and spatially. The research that underpins this chapter was conducted using a variety of qualitative methods: specifically, interviews with key people involved in the process of drafting education policy documents and analysis of such documents used in the making of the state curriculum. Interviews have been conducted with one of the authors of the curriculum, and with others responsible for curriculum development at the National Agency for Education. Policy documents from the Swedish Ministry of Education, from the National Agency for Education, and from curriculum developers have also been analysed. This chapter includes research findings based on the analysis of such material and reflections about how these sources of evidence can increase our knowledge of thinking geographically and spatially.

    Re-contextualising development in teaching school geography: Teachers' story in Sweden and China2016In: Eurogeo conference 2016, Malaga, 2016Conference paper (Other academic)
    Abstract [en]

    Geography as a school subject varies in different nations. This comparative study is based on legitimation code analysis of the two countries’ Geography National Curriculum in compulsory secondary education (Year7-9) respectively. It follows with a school case study on Chinese and Swedish teachers' interpretation about development topic in their teaching, which is the process of re-contextualisation in practical classroom when transforming the idea on the paper to action in teaching. The main outcomes show how knowledge is described in the curriculum standards, and the teachers' case study gives insight in how and in what ways we could transform the hypothesis to practice, thus enhance the view of knowledge in the curriculum.

    Abused women’s vulnerability in daily life and in contact with psychiatric care: in the light of a caring science perspective2017In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 26, no 15-16, p. 2384-2391Article in journal (Refereed)
    Abstract [en]

    Aims and objectives

    The aim of the study is to deepen the understanding of abused women's vulnerability in relation to how the abuse and encounters with health care professionals affect life. A further aim is to highlight abused women's vulnerability with a caring science perspective.

    Background

    Experience of abuse has consequences for the mental health of women and girls. Abused women may experience health care as unsupportive, and as a result, often chose not to disclose their experiences of abuse.

    Design and methods

    The results of two qualitative empirical studies were analysed along with a phenomenological meaning analysis in accordance with the methodological principles of Reflective Lifeworld Research.

    Findings

    Living one's life with experiences of abuse implies vulnerability, which can prevent abused women from achieving good health. This vulnerability results from insecurity regarding identity, along with the sense that one could have been a different individual if it were not for the abuse and thereby have a more fair chance in life. Being cared for within general psychiatric care could further increase this vulnerability. The healthcare professional's ability to care for the women who have experienced abuse leads to either an encounter of trust or else further suffering for the women.

    Conclusion

    A lifeworld-oriented caring science perspective as a foundation for care can contribute to care for abused women which reaches the existential dimensions of their vulnerability and vulnerable life situation.

    Relevance to clinical practice

    It is evident that healthcare professionals should deepen their understanding of how abused women live, within a general psychiatric context. This study enables a deeper understanding of abused women's vulnerability in relation to how the abuse and encounters with healthcare professionals affect life.

    The unnecessary suffering and abuse caused by healthcare professionals needs to stop: a study regarding experiences of abuse among female patients in a general psychiatric setting2017In: Clinical Nursing Studies, ISSN 2324-7940, E-ISSN 2324-7959, Vol. 5, no 4, p. 59-64Article in journal (Refereed)
    Abstract [en]

    Objective: Healthcare, from a caring science perspective, aims to support the patients’ health processes. All healthcare is, however, not experienced as being caring by the patients. Consequences of abuse in healthcare (AHC) services have effects on the patients’ health and well-being. The aim of this study was to explore experiences of abuse from healthcare professionals among female patients in a general psychiatric clinic.

    Methods: In the cross-sectional study design, data from female patients receiving outpatient or inpatient care at a general psychiatric clinic about their experiences of abuse were gathered by using the NorVold Abuse Questionnaire (NorAQ). Descriptive statistics were used to describe experiences of abuse in the health care sector.

    Results: Fifty-six women reported abuse by healthcare professionals. Being offended or grossly degraded while visiting health services, was experienced by almost all the women (n = 50). Experiences that a “normal” event while visiting health services suddenly became a really terrible and insulting experience, without fully knowing how this could happen was experienced by 38 women in the study. During their current care episode at the general psychiatric clinic a majority of the female patients chose not to reveal their experiences of abuse in the health care sector (n = 34).

    Conclusions: The fact that patients experience suffering and abuse from healthcare professionals is a serious problem that needs to be highlighted and discussed within all healthcare contexts. Attention needs to be paid to the suffering and abuse that is related to encounters and relationships between patients and healthcare professionals.

    Entrepreneurial actors between two systems of norms - Profound and professional quality knowledge in Swedish health care2011Conference paper (Other academic)
    Abstract [en]

    In an imprecise sense, quality has always been an issue for health care and its actors. Quality issues are of great importance, since they intersect at the very core of a democratic health care delivery system, i.e. the authorities´ and the public´s demand for information confront the medical profession´s demand for self-regulation. The innovation of Swedish national quality registers contains important primary data that can play a significant role for control and improvement of health care. The medical profession started the first national register in 1975 for their opportunities of comparing methods of treatment. In the 1990s indicators generated from the national quality registers opened a new way for authorities to govern, control and improve knowledge about the quality in health care. Now, new demands are rising in a third practical application: public transparency, with a view to facilitate patient choice and improve quality of choices. A fundamental question is how the translation of primary data in national quality registers has been made feasible. Three puzzles are highly significant in this case; the medical profession´s degree of control over the information, the type of information that should be delivered to national and local authorities such as the National Board of Health and Welfare, Swedish Association of Local Authorities and the County Councils and to what extent the public should have access to the information. These puzzles are handled by entrepreneurs. They make the information in national quality registers comprehensible and manageable to initiate new ways of thinking, start new projects and take risks over time in the shaping of new institutional arrangements. Thus, the aim of this paper is to examine political entrepreneurship in order to understand how different actors use and translate information in quality registers.

    Kvalitetsbegreppet i lagstiftningen inom den mänskliga sektorn: - en översikt2013Report (Other academic)
    Abstract [sv]

    Denna undersökning behandlar hur olika kvalitetsaspekter i några utvalda sektorslagar förhåller sig till varandra inom hälso- och sjukvård, polis- och kriminalvård, utbildning samt vissa kommunala lagar. Alla befinner sig i den s.k. mänskliga sektorn av offentlig verksamhet. Den bakomliggande orsaken till detta är att Innovationsrådet vill fördjupa kunskapen om hur begreppet kvalitet definieras och används i svensk lagstiftning och i förarbetena till vissa lagar. Undersökningen strävar inte efter att generera någon legaldefinition av begreppet kvalitet.

    Kvalitetsbegreppet delas in i aspekterna; struktur, process och resultat i en analysmodell i form av en matris som även tar hänsyn till personal och medborgarperspektiv. Strukturkvalitet speglar förutsättningarna för eller inflödet i en verksamhet, processkvalitet belyser de aktiviteter som görs i verksamheten och resultatkvalitet återger prestationerna och effekterna av verksamheten. Med hjälp av analysmodellen skapas ett mönster över vilka aspekter som tydligast framträder i lagarna och förarbeten samt vilket perspektiv som är mest påtagligt i respektive lag. Genom analysmodellen har en överblick över varje sektor kunnat ges.

    Undersökningen är en dokumentstudie och baseras på lagtexter med relaterade propositioner samt statliga utredningar. De utvalda lagarna återfinns i bilaga 1. I analysen av materialet har först kvantitativa sökningar gjort på kvalitet och relaterade begrepp såsom kvalitetssäkring, kvalitetsgranskning, kvalitetskontroll samt kvalitetsutvärdering för att få en bild av om kvalitet är ett återkommande begrepp eller inte. Därefter har en granskning och tolkning gjorts för att utreda ur vilka aspekter som kvalitet beskrivs, samt vilket perspektiv som väger tyngst i skrivningar i lagen och dess förarbeten.

    Varje sektor är resultatredovisad för sig i särskilda avsnitt. Resultaten visar att kvalitetsbegreppet inom hälso- och sjukvården är frekvent förekommande ur aspekterna struktur och resultat, medan resultatkvalitet överlämnats till den autonoma medicinska professionen att definiera. I utbildningssektorn tycks förhållandet vara det motsatta där resultatkvalitet i form av måluppfyllelse är det centrala och betonas starkt även kvalitet i termer av struktur och process förekommer. Även i denna sektor lyfter lagstiftaren fram autonomi och egenkontroll i avseende på utbildning och forskning när det gäller att definiera vad som är god kvalitet i vetenskapliga processer och resultat.

    Inom socialtjänsten pågår ett arbete som syftar till att ta fram kvalitetsindikatorer ur olika aspekter inspirerat av hälso- och sjukvården. Idag är begreppet kvalitet tydligast uttryckt i socialtjänstlagen när det gäller aspekterna struktur och process i ett personalperspektiv. Även inom polis och kriminalvård tycks kvalitetsbegreppet öka i betydelse även i lagtexterna, där struktur- och processaspekter framkommer i kriminalvårdens nya fängelse- och häkteslagstftningen. I polislagen lyser dock begreppet kvalitet med sin frånvaro, vilket i sig inte hindrar att krav ställs på kvalitet genom andra kanaler.

    Undersökningen avslutas med en diskussion utifrån de sektorsvisa resultaten om behov av ständigt återkommande omprövningar av hur begreppet ska användas i lagen och avvägningar om risken för cementering av verksamheter å ena sida och rättsäkerhet samt tydlighet å den andra.

    Mapping via Time-Geography to Elucidate Institutional, Economic and Political Change2012In: Proceedings of 15th Uddevalla Symposium,2012, Entrepreneurship and Innovation Networks / [ed] Iréne Bernhard, Bohus: Ale Tryckteam , 2012, p. 1-10Conference paper (Refereed)
    Abstract [en]

    Change has always been an issue for studies in politics and economics. However, there are few systematic treatments of institutions. This paper exemplifies how institutions (i.e., rules, norms and conventions) relate to the time-geography concepts of constraints, which affect different agents, policy-making, as well as economic performance.This paper seeks to advance the current discussion and sets some groundwork for further elaboration on economic and political change from an ontological perspective based in time-geography. It offers an initial exploration of the analysis of institutional change by a conceptualization of constraints in time-geography.The contribution of this study lies in the fact that insights from a time-geography approach have the ability to make the evolutionary perspective more coherent in empirically-related works when grading and ordering institutions of relevance concerning economic and political evolvement.

    Mellan kunskap och politik: Kvalitetssystem och offentlig kunskapsstyrning i hälso- och sjukvården2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The aim with this thesis is to describe the quality development in Swedish healthcare from an institutional perspective, analyse implications of the development concerning the relationship between the medical profession and the public administrative system and discuss consequences for political direction and welfare organization. The study is based on four case studies and one conceptual analysis.

    The main conclusion is that the medical quality systems have been imbedded in the political management alongside the development towards a public knowledge management. The analysis has more specifically uncovered that quality registries in healthcare have been influenced by political ideologies, management ideas and ideas of transparency. It is also clear that open comparisons were an ‘unintended consequence’ of the quality registry development that has enhanced the development towards a public knowledge management.

    The analysis also shows that public knowledge management challenges the ideal of democratic enlightened understanding. The development of public knowledge management in the healthcare sector raises the question of who is governing whom in Swedish healthcare.

    Policymaking through healthcare registries in Sweden2018In: Health Promotion International, ISSN 0957-4824, E-ISSN 1460-2245, Vol. 33, no 2, p. 356-365Article in journal (Refereed)
    Abstract [en]

    Healthcare registries, otherwise known in Sweden as national quality registries (NQRs), have progressed from being a patient-focused system supporting medical results to become the basis of a health policy steering instrument called regional comparisons (RCs). This article seeks to explain RCs as an unintended consequence of the NQR development, by utilizing the concepts of policy entrepreneurs and streams of impact: the problem stream (problem perceived), the policy stream (what is valid), and the political stream (governmental objectives). The empirical contribution lies in insights on how the RCs have developed as an unintended consequence of entrepreneurial deliberate action in the process of creating NQRs. These findings are based on documents, interviews, and previous research in the social sciences. The article also argues for a critical understanding of public knowledge management (PKM) related to experiences in the development of NQRs regarding how to use knowledge in healthcare government. This article highlights how knowledge generated in quality systems based on registries could imply a stronger role for authorities in exerting control over the medical profession. It also discusses the potential use of research evidence on NQRs as a base for more efficient policymaking.

    What frames Quality Registers in Swedish Health Care: an institutional approach2011In: Proceedings from 14th Uddevalla Symposium, 2011 Entrepreneurial Knowledge, Technology and Transformation of Regions / [ed] Iréne Bernhard, Trollhättan: Högskolan Väst , 2011, p. 1-19Conference paper (Refereed)
    Abstract [en]

    Quality issues strike the classical conflict in a democratic health-care deliverysystem of different interests among the politicians, the medical profession andpublic officials. This cannot be studied as a cut-off whiz. Quality registers havedeveloped over the past 40 years. Therefore, this paper puts the innovation ofquality registers in an institutional perspective. Two things are essential in thispaper. First, this paper reviews the emergence of quality registers in Swedish healthcare as an effect of institutional arrangements. Second, it analyses the interactionof diverse factors in different institutional settings and logics. The relevant data forthe study was collected from official/unofficial policy documents and key actorinterviews.The empirical findings show that three different waves of development can betraced in history that has highly affected the development of quality registers. Italso shows that medical quality is framed and determined by physicians in line withprofessional knowledge and by the primary institutional logic of quality in medicalcare. However, organisational quality in health care is framed by the logic ofpublic equity of access based on a third party payer and the logic of managerialcontrol. These two paths of quality developments are now federating in aninstitutional logic of transparency. The contribution of this paper is importantbecause it produces insights in different institutional logics, which frames the riseof the two quality paths and the problems they have to face in order to merge. It also enhances the existing knowledge that institutions matter.

    Implementering i vården: En kunskapsöversikt om beslutsnivåer och professionsperspektiv2018Report (Other academic)
    Abstract [sv]

    Hälso- och sjukvården liksom socialtjänsten är under ständig förändring – medicinska framsteg skapar nya möjligheter till behandling samtidigt som behoven av hälso- och sjukvård och socialtjänst ökar i takt med att allt fler lever längre med kroniska sjukdomar. Socialtjänsten kommer att behöva stödja fler med långvariga och komplexa behov, vilket band annat kommer att ställa krav på ändrade arbetssätt. En fortsatt utveckling i vården och omsorgen är viktigt för att i dag och i framtiden kunna tillhandahålla en god vård och omsorg som patienter och brukare känner förtroende för.Samtidigt finns tecken på att utvecklingen och lärandet inte sker i den omfattning som behövs. I olika analyser har Vårdanalys genom åren visat att lärandet mellan olika verksamheter och huvudmän är begränsat. Orsakerna bakom det är flera.Hösten 2017 initierade vi ett forskningsuppdrag med ambitionen att utifrån litteraturen identifiera övergripande utmaningar när det gäller implementering i hälso- och sjukvården och socialtjänsten. Vi gav professor Mattias Elg och postdoktor Mattias Örnerheim vid institutionen för ekonomisk och industriell utveckling (IEI), Linköpings universitet, uppdraget att presentera en kunskapsöversikt på detta tema.Deras översikt har varit ett värdefullt bidrag till Vårdanalys arbeten under 2017 och 2018 som på olika sätt analyserat utvecklingsarbete och deras förutsättningar att bidra till långsiktig utveckling. Det är vår förhoppning att den här promemorian kan tjäna som ett kunskapsunderlag i den fortsatta diskussionen om hur vi kan skapa bättre förutsättningar till lärande och utveckling i vården och omsorgen.Den här promemorian är författarnas redovisning av forskningsuppdraget i sin helhet och de står själva för innehållet.

    Explaining Quality Management in the Danish and Swedish Public Health Sectors: Unintended Learning and Deliberate Co-Optation2016In: International Journal of Public Administration, ISSN 0190-0692, E-ISSN 1532-4265, Vol. 39, no 12, p. 963-975Article in journal (Refereed)
    Abstract [en]

    This article examines the development of diverse quality systems in the otherwise quite similar Danish and Swedish public health sectors. After decades of numerous piecemeal medical and managerial quality development programs in both countries, a nationwide mandatory accreditation system was introduced in the Danish health services in 2009. Nationwide quality indicator projects are also found in Sweden, but there has been political attempt to introduce a compulsory system. This article seeks to explain this difference. It argues, first, that resistance from the medical professions blocked the introduction of compulsory, nationwide quality systems in both countries for decades. Second, the implementation of the Danish accreditation system was triggered by a combination of unintended policy learning produced by local reforms in two counties and of the Ministry of Health’s carefully orchestrated policy process that served to co-opt critical voices in the medical profession.

    Path Dependence on New Roads. Institutional Development of Quality Registers2014In: Offentlig Förvaltning. Scandinavian Journal of Public Administration, ISSN 2000-8058, E-ISSN 2001-3310, Vol. 18, no 2, p. 3-22Article in journal (Refereed)
    Abstract [en]

    When explaining social development and changes in public administration, institutional changeis a typical focus. Institutional analysis can combine the analyses of changes on the basis offormal legal and informal arrangements; it commonly shows that institutions lead to inertiawhere changes over time are concerned. Political aims are a guide to how organizations aredesigned and governed. When goals and earlier decisions clearly guide change, path dependenceis a fundamental concept when explaining change. However, this analysis shows how andwhen quality registers appeared as an answer to changes in institutional arrangements in Swedishpublic healthcare. Through three phases, cumulative processes have been visible and theprocesses have been followed by an improved and increased usage of quality registers andother quality systems. This analysis shows that institutional development can be pathdependentin relation to methods and means. Despite changing goals over time, quality registersas a policy tool have been path-dependent and stayed firm. Thus, it is important to see alsoorganisational methods as a development path that can be used to implement even new policyaims.

    Physical performance, injuries and osteoarthrosis in female soccer2001Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The overall purpose was to investigate female soccer regarding injuries, risk factors, posttraumatic OA and non-traumatic OA. A prospective study of injuries in eight female soccer teams, from the six available levels, was performed during one season. The total injury rate was 14.3 and 3.7/1000 game and practice hours, respectively. The knee (26%) was the most common place for injury, followed by the foot (12%). An increased general joint laxity was found to be a significant risk factor for general injury and knee injury. In an attempt to find easy functional tests that do not require advanced equipment and that could be used instead of more advanced isokinetic tests, only low correlations between isokinetic strength measurements and functional tests, such as one-leg hop, triple jump, vertical jump, one-leg rising or square hop, were found. There were no differences in any of the tests found between players under /over the age of 20, except for knee flexor muscle strength, where a small but significant difference was seen. Female soccer players with ACL injury showed radiographic changes in the in 69%, and verified knee OA in 34% at the age of 31, 12 years after injury. A majority of the players suffered from symptoms affecting their sport and recreational activities and knee-related quality of life. However, the symptoms were not related to the presence of OA or having undergone surgery to the affected knee or not. Somewhat older female ex-soccer players (mean age 42 years) showed a prevalence of 3% and 17% of radiographic hip and knee OA, and had, with and without knee injuries, a 5-fold increased rate of knee osteoarthrosis compared to non-sporting females age 46, when age and BMI were adjusted for. No difference was seen between the female players and the non-sporting controls regarding hip OA. Increased general joint laxity was found to be a risk factor for injury. Female soccer players with an ACL injury had verified knee OA in 34% at the age of 31, 12 years after injury. Also, somewhat older female players after their career showed a high prevalence of radiographic knee OA and a 5-fold risk of developing knee OA compared to controls. Female soccer by itself and in combination with the high risk of knee injuries has an increased risk of OA. However, the positive effects of exercise, physical and mental, when playing soccer should not be ignored.

    Isokinetic knee extensor strength and functional performance in healthy female soccer players1998In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 8, no 5, p. 257-264Article in journal (Refereed)
    Abstract [en]

    The aims of this study were to determine the relationship between isokinetic knee extensor muscle strength at 60 degrees/s and 180 degrees/s and five functional performance tests (one-leg-hop, triple-jump, vertical-jump, one-leg-rising and square-hop), to determine the relationship between the five different functional performance tests and to present normative data and limb symmetry index concerning healthy female soccer players. In total 101 female soccer players (X = 20.3 years) were tested. A limb symmetry index, using weak/strong leg, varied from 83.9 to 96.3 in the tests. Between the functional performance tests there were in general correlations of r = 0.4-0.8 (P < 0.001). A correlation of r = 0.77 (P < 0.001) was obtained between one-leg-hop and triple-jump. No differences were found between the right and the left leg or the dominant and the non-dominant leg. Using linear regression models corrected for body weight, height and age, there were low correlations between the isokinetic strength measurements and the functional tests. It is not recommended using functional performance testing and isokinetic testing interchangeably.

    Physical capacity in female soccer players: does age make a difference?2000In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 2, no 1, p. 39-48Article in journal (Refereed)
    Abstract [en]

    There is an increased risk of injuries, especially knee injuries, in young female soccer players. If age-related differences in physical capacity could be identified, the possibilities for injury prevention may increase. The objective was to study possible age-related differences in isokinetic muscle strength, aerobic capacity, functional performance, and general joint laxity in female soccer players. Body mass index (BMI) (kg × m-2) was also measured. In total 108 players, recruited from seven soccer teams, were tested. The mean age was 20.2 years (SD=4.1, range=14-30). Players aged ≦20 years and>20 years were compared. The following tests were employed: isokinetic knee extensor and flexor strength at velocities of 60 °/s and 180°/s, one-leg hop, triple jump, vertical jump, square-hop, and aerobic capacity. The older group had greater isokinetic strength for the flexor muscles at a peak torque of 60°/s (p=0.04), and total work at 60°/s and 180°/s (p=0.04 and 0.03). The older group had a higher BMI and more years of soccer playing (p≪0.001). The results revealed no significant differences between the age groups regarding, functional performance, aerobic capacity, or general joint laxity. Further studies are needed on intrinsic risk factors to identify variables explaining the difference in injury rate between younger and older players.

    Injury risk factors in female European football: a prospective study of 123 players during one season2000In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 10, no 5, p. 279-285Article in journal (Refereed)
    Abstract [en]

    The purpose of this study was to register prospectively the injuries in female soccer and to study their correlation to potential risk factors. A total of 123 senior players from eight teams of different levels were followed during one season. Isokinetic knee muscle strength at 60 and 180 degrees/s, one-leg-hop, vertical jump, square-hop, and continuous multistage fitness test (MFT) were tested at the end of the pre-season. In addition, Body Mass Index (BMI) and general joint laxity were measured. During the season, April-October, all injuries resulting in absence from one practice/game or more were registered. Forty-seven of the 123 players sustained altogether 65 injuries. The total injury rate was 14.3 per 1000 game hours and 3.7 per 1000 practice hours. The knee (26%) was the most commonly injured region followed by the foot (12%), ankle (11%), thigh (11%) and back (11%). The risk of sustaining moderate and major injuries increased in the later part of the game or practice. Significant risk factors for injuries were an increased general joint laxity (odds ratio (OR)=5.3, P<0.001), a high performance in the functional test square-hop (OR=4.3, P=0.002), and an age over 25 years (OR=3.7, P=0.01). The injury rate was not different compared to male soccer, but knee injuries were more common, which is in accordance with previous studies. None of the risk factors identified in this study is easily applicable for future intervention studies in the attempts to reduce the injury rate in female soccer.

    Analysis of pure methods using garbage collection2012In: Proceedings of the 2012 ACM SIGPLAN Workshop on Memory Systems Performance and Correctness, ACM Press, 2012, p. 48-57Conference paper (Refereed)
    Abstract [en]

    Parallelization and other optimizations often depend on static dependence analysis. This approach requires methods to be independent regardless of the input data, which is not always the case.

    Our contribution is a dynamic analysis "guessing" if methods are pure, i. e., if they do not change state. The analysis is piggybacking on a garbage collector, more specifically, a concurrent, replicating garbage collector. It guesses whether objects are immutable by looking at actual mutations observed by the garbage collector. The analysis is essentially for free. In fact, our concurrent garbage collector including analysis outperforms Boehm's stop-the-world collector (without any analysis), as we show in experiments. Moreover, false guesses can be rolled back efficiently.

    The results can be used for just-in-time parallelization allowing an automatic parallelization of methods that are pure over certain periods of time. Hence, compared to parallelization based on static dependence analysis, more programs potentially benefit from parallelization.

    Block-free concurrent GC: Stack scanning and copying2016In: ISMM 2016: Proceedings of the 2016 ACM SIGPLAN International Symposium on Memory Management, ACM Press, 2016, p. 1-12Conference paper (Refereed)
    Abstract [en]

    On-the-fly Garbage Collectors (GCs) are the state-of-the-art concurrent GC algorithms today. Everything is done concurrently, but phases are separated by blocking handshakes. Hence, progress relies on the scheduler to let application threads (mutators) run into GC checkpoints to reply to the handshakes. For a non-blocking GC, these blocking handshakes need to be addressed. Therefore, we propose a new non-blocking handshake to replace previous blocking handshakes. It guarantees schedulingindependent operation level progress without blocking. It is scheduling independent but requires some other OS support. It allows bounded waiting for threads that are currently running on a processor, regardless of threads that are not running on a processor. We discuss this non-blocking handshake in two GC algorithms for stack scanning and copying objects. They pave way for a future completely non-blocking GC by solving hard open theory problems when OS support is permitted. The GC algorithms were integrated to the G1 GC of OpenJDK for Java. GC pause times were reduced to 12.5% compared to the original G1 on average in DaCapo. For a memory intense benchmark, latencies were reduced from 174 ms to 0.67 ms for the 99.99% percentile. The improved latency comes at a cost of 15% lower throughput.

    Concurrent Compaction using a Field Pinning Protocol2015In: ISMM 2015 Proceedings of the 2015 ACM SIGPLAN International Symposium on Memory Management, ACM Press, 2015, Vol. 50(11), p. 56-69Conference paper (Refereed)
    Abstract [en]

    Compaction of memory in long running systems has always been important. The latency of compaction increases in today’s systems with high memory demands and large heaps. To deal with this problem, we present a lock-free protocol allowing for copying concurrent with the application running, which reduces the latencies of compaction radically. It pro- vides theoretical progress guarantees for copying and appli- cation threads without making it practically infeasible, with performance overheads of 20% on average. The algorithm paves way for a future lock-free Garbage Collector.
