    Diana och Endymions kärlek: En receptionsestetisk studie av tre franska 1700-talsmålningar föreställande Diana och Endymion2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen behandlar myten om Diana och Endymion i 1700-talets franska måleri där tre målningar föreställande Diana och Endymion studeras. Den första är av Jean-Honoré Fragonard och de två andra är av Louis-Jean-François Lagrenée. Syftet är att undersöka hur målningarna skildrar myten, därför används de antika källtexterna som behandlar Endymionmyten som stöd i analysen. Målningarna studeras även i relation till hur den grekiska och romerska mytologin behandlades i konsten under 1700-talet i Frankrike samt vilka ideal som påverkade bildkonsten vid den här tiden. Det som lyfts fram är det som är relevant för myten om Diana och Endymion. Det teoretiska perspektivet utgår från Kemps receptionsestetik och metoden är komparativ där målningarna jämförs med varandra.

    Resultatet visar att det centrala i målningarna är kärleksrelationen mellan Diana och Endymion och att det är Diana som har den aktiva rollen i relationen och Endymion den passiva när han blir objektifierad. Detta förhållande motsvararar beskrivningen i de antika källtexterna. Förhållandet kan sägas gå emot de traditionella könsrollerna vilket var en aktuell fråga vid tiden då målningarna skapades. Målningarna skildrar förbindelsen mellan Diana och Endymion både på olika och på liknande sätt. En viktig skillnad är att kärleken får en lekfull betoning i Fragonards verk medan den i Lagrenées verk får en tydligare erotisk underton.

    Structural studies of tri-functional human GART2010In: Nucleic Acids Research, ISSN 0305-1048, E-ISSN 1362-4962, Vol. 38, no 20, p. 7308-19Article in journal (Refereed)
    Abstract [en]

    Human purine de novo synthesis pathway contains several multi-functional enzymes, one of which, tri-functional GART, contains three enzymatic activities in a single polypeptide chain. We have solved structures of two domains bearing separate catalytic functions: glycinamide ribonucleotide synthetase and aminoimidazole ribonucleotide synthetase. Structures are compared with those of homologous enzymes from prokaryotes and analyzed in terms of the catalytic mechanism. We also report small angle X-ray scattering models for the full-length protein. These models are consistent with the enzyme forming a dimer through the middle domain. The protein has an approximate seesaw geometry where terminal enzyme units display high mobility owing to flexible linker segments. This resilient seesaw shape may facilitate internal substrate/product transfer or forwarding to other enzymes in the pathway.

    Dag Wellander: Meaning – memory: oblivion. A reading of Birgitta Trotzig’s The mud kings daughter. Master of Arts paper. Written in Swedish. 115 pp. Department of Literature and History of Ideas, Stockholm University, SE – 106 91 Stockholm

    The purpose of the paper is to treat one question, including the consequences of it’s answer, the question if The mud kings daughter is a text that has meaning. The question is in a first series of steps being approached by the way of scrutinizing the meaning found in the text in accordance with the methodology applied by those four dissertations that are available on the subject, i.e. on The mud kings daughter. These examinations do not find that the alleged forms of meaning stated by the dissertations is being produced by the text. On the contrary striking similarities is being found between these alleged forms of meaning on the one hand, and on the other the unfounded, disambiguated meaning that, according to Shoshana Felman, Freudian and anti-Freudian critics alike, have said is to be found in Henry James’ short novel The Turn of the Screw. In a following series of steps – some of which are being taken on Jacques Derrida’s advice – the rhetorical functioning of the textual ambiguity is observed and often found to be enchanting, whereupon the rhetorical necessity of the textual ambiguity is found to be affliction.

    This split between the rhetorical functioning of the textual ambiguity as rather enchanting, and the rhetorical necessity of the textual ambiguity being affliction, is then treated as something that hardly could be understood, and, accordingly, as something that might be understood as something that could not be understood. The idea is being put in that this split could be thought of as an inversion of oblivion into a living memory of a forgotten reading impression, an idea that is being inspired by the inversion of oblivion into a living memory in Marcel Proust’s In Search of Lost Time.

    Keywords: Birgitta Trotzig, Shoshana Felman, Jacques Derrida, Marcel Proust, meaning, ambiguity, memory, oblivion.

    Does Prevention Pay? Costs and Potential Cost-savings of School Interventions Targeting Children with Mental Health Problems2016In: Journal of Mental Health Policy and Economics, ISSN 1091-4358, E-ISSN 1099-176X, Vol. 19, no 2, p. 91-101Article in journal (Refereed)
    Abstract [en]

    Background: In Sweden, the local government is responsible for funding schools in their district. One funding initiative is for schools to provide students with mental health problems with additional support via extra teachers, personal assistants, and special education classes. There are evidence-based preventive interventions delivered in schools, which have been shown to decrease the levels of students' mental health problems. However, little is known about how much the local government currently spends on students' mental health support and if evidence-based interventions could be financially beneficial. Aims of the Study: The aim of this study was to estimate the costs of providing additional support for students' mental health problems and the potential cost-offsets, defined as reduced school-based additional support, if two evidence-based school interventions targeting children's mental health problems were implemented in routine practice. Methods: This study uses data on the additional support students with mental health problems received in schools. Data was collected from one school district for students aged 6 to 16 years. We modeled two Swedish school interventions, Comet for Teachers and Social and Emotional Training (SET), which both had evidence of reducing mental health problems. We used a cost-offset analysis framework, assuming both interventions were fully implemented throughout the whole school district. Based on the published studies, the expected effects and the costs of the interventions were calculated. We defined the cost-offsets as the amount of predicted averted additional support for students with ongoing mental health problems who might no longer require receiving services such as one-on-one time with an extra teacher, a personal assistant, or to be placed in a special education classroom. A cost-offset analysis, from a payer's perspective (the local government responsible for school financing), was conducted comparing the costs of both interventions with the potential cost-savings due to a reduction in the prevalence of mental health problems and averted additional support required. Results: The school district was comprised of 6,256 students, with 310 students receiving additional support for their mental health problems. Of these, 143 received support in their original school due to either having ADHD (n = 111), psychosocial problems (n = 26), or anxiety/depression (n = 6). The payers' total cost of additional support was 2,637,850 Euro per school year (18,447 Euro per student). The cost of running both interventions for the school district was 953,643 Euro for one year, while the potential savings for these interventions were estimated to be 627,150 Euro. The estimated effects showed that there would be a reduction of students needing additional support (25 for ADHD, eight for psychosocial problems, and one for anxiety/depression), and the payer would receive a return on their invested resources in less than two years (1.5 years) after implementation. Discussion: Preventive school interventions can both improve some children's mental health problems and be financially beneficial for the payer. However, they are still limited in their scope of reducing all students' mental health statuses to below clinical cut-offs; therefore, the preventive school interventions should be used as a supplement, but not a replacement, to current practices. Implications for Health Policies: The findings have political and societal implications, in that payers can reallocate their funds toward preventive measures targeting students' mental health problems, while reducing the costs. Implications for Future Research: When evaluating public health actions, it is necessary to consider their economic impact. The resources are scarce and the decision makers need knowledge on how to allocate their resources in an efficient way. Cost-offset analysis is seen as one way for decision makers to comprehend research findings; however, such analyses tend to not include the full benefits of the interventions, and actual impacts need to be fully evaluated in routine implementation.

    Islam in Aru, Indonesia: Oral traditions and Islamisation processes from the early modern period to the present2019In: Indonesia and the Malay World, ISSN 1363-9811, E-ISSN 1469-8382Article in journal (Refereed)
    Abstract [en]

    The coming of Islam in eastern Indonesia is generally assigned to the activities of Muslim traders from the late 15th century onwards. This assumption is an over-simplification, especially in areas outside the main trade centres. In the Aru islands, Islam was introduced by the mid 17th century. We argue that Islamisation in Aru was initially a matter of internal considerations, rather than trade. We present oral traditions about the expansion of Islam as seen from two locations: Ujir, the historical Muslim centre in Aru on the west coast, and Benjuring, a former stronghold of local ancestral beliefs in the east. The oral sources are juxtaposed with European accounts of the 17th century when Muslim and Protestant centres first developed in Aru. The coming of Islam forced people to either convert or leave for non-Muslim areas. By late colonial times (early 20th century), both Islam and the Protestant church had reached remote villages. The most recent wave of conversions in Aru to state-approved world religions took place in the 1970s. In the last 30 years, the population in Aru has grown, especially in the regency capital Dobo. While Muslims used to be a small minority in Aru with their main centre on Ujir island, the point of gravity has shifted to Dobo, a fast-growing town with a large influx of mostly Muslims from other parts of Indonesia. Islamisation is still ongoing in Aru and the character of Islam is changing.

    Nonlinear mushy-layer convection with chimneys: stability and optimal solute fluxes2013In: Journal of Fluid Mechanics, ISSN 0022-1120, E-ISSN 1469-7645, Vol. 716, p. 203-227Article in journal (Refereed)
    Abstract [en]

    We model buoyancy-driven convection with chimneys - channels of zero solid fraction - in a mushy layer formed during directional solidification of a binary alloy in two dimensions. A large suite of numerical simulations is combined with scaling analysis in order to study the parametric dependence of the flow. Stability boundaries are calculated for states of finite-amplitude convection with chimneys, which for a narrow domain can be interpreted in terms of a modified Rayleigh number criterion based on the domain width and mushy-layer permeability. For solidification in a wide domain with multiple chimneys, it has previously been hypothesized that the chimney spacing will adjust to optimize the rate of removal of potential energy from the system. For a wide variety of initial liquid concentration conditions, we consider the detailed flow structure in this optimal state and derive scaling laws for how the flow evolves as the strength of convection increases. For moderate mushy-layer Rayleigh numbers these flow properties support a solute flux that increases linearly with Rayleigh number. This behaviour does not persist indefinitely, however, with porosity-dependent flow saturation resulting in sublinear growth of the solute flux for sufficiently large Rayleigh numbers. Finally, we consider the influence of the porosity dependence of permeability, with a cubic function and a Carman-Kozeny permeability yielding qualitatively similar system dynamics and flow profiles for the optimal states.

    Physical Inactivity From Adolescence to Young Adulthood: The Relevance of Various Dimensions of Inequality in a Swedish Longitudinal Sample2017In: Health Education & Behavior, ISSN 1090-1981, E-ISSN 1552-6127, Vol. 44, no 3, p. 376-384Article in journal (Refereed)
    Abstract [en]

    As physical inactivity may track from adolescence to adulthood, it is important to identify social determinants of physical inactivity in early life. However, most studies have measured socioeconomic position as one dimension. We examine whether multiple dimensions of socioeconomic position, in addition to other dimensions of inequality (i.e., gender, immigrant background), associate with physical inactivity at two time points in youth. Longitudinal data were drawn from the Swedish Level of Living Survey (N = 765) and analysed by gender-stratified logistic regression. Among girls, low parental social class (odds ratio [OR] = 2.63, 95% confidence interval [CI; 1.28, 5.42]) and income (OR = 2.28, 95% [CI 1.12, 4.65]) were associated with physical inactivity, while immigrant background (OR = 2.33, 95% CI [1.03, 5.23]) and a low level of parental education (OR = 3.38, 95% CI [1.15, 9.95]) predicted physical inactivity among women. Among boys, low parental income (OR = 3.27, 95% CI [1.39, 7.69]) was associated with physical inactivity, whereas immigrant background (OR = 2.29, 95% CI [1.04, 5.03]) predicted physical inactivity among men. Our results suggest that physical inactivity is socially patterned, but different dimensions of social stratification should not be considered interchangeable as they may operate independently, through intersection with gender, and at different time points in youth in increasing the risk of physical inactivity.

    Parental education differentially predicts young adults' frequency and quantity of alcohol use in a longitudinal Swedish sample2018In: SSM - Population Health, ISSN 2352-8273, Vol. 6, p. 91-97Article in journal (Refereed)
    Abstract [en]

    Background

    Alcohol consumption contributes to health inequalities, but few studies have examined how socially differentiated alcohol use develops across the life course. In this study, we examine how one aspect of childhood socioeconomic position (parental education) relates to two often-conflated young adult drinking patterns: drinking frequency and quantity per occasion. Using a life course perspective, we also explore whether parental drinking patterns or young adults’ own educational attainment might account for such associations.

    Methods

    This study used longitudinal data from the nationally representative Swedish Level of Living Surveys (LNU). Young adults’ (aged 20–28, n = 803) drinking patterns and educational attainment were determined through the LNU 2010 and official registers. A decade earlier, parents self-reported their education and drinking patterns in the LNU 2000 and Partner-LNU 2000.

    Results

    Logistic regression models showed that high parental education predicted young adult frequent drinking, while low parental education predicted young adult high quantity drinking. Drinking patterns were associated inter-generationally, but parental alcohol use did not account for differences in young adult drinking patterns by parental education. Young adults’ own education similarly predicted their drinking patterns but did not account for differences in drinking frequency by parental education. Differences in drinking quantity by parental education were no longer significant when young adults’ own education was included in the final model.

    Conclusions

    Findings suggest that parental education constitutes an early-life structural position that confers differential risk for young adult drinking patterns. Young adults whose parents had low education were less likely to drink frequently but were more likely to drink heavily per occasion, a drinking pattern that may place more disadvantaged young adults at a greater health risk.

    Is all support equal? Head Start preschool teachers' psychological job attitudes2017In: Teaching and Teacher Education: An International Journal of Research and Studies, ISSN 0742-051X, E-ISSN 1879-2480, Vol. 63, p. 103-115Article in journal (Refereed)
    Abstract [en]

    Head Start preschool teachers are at risk for quitting their employment if they have negative job attitudes. Using a semi-structured interview guide, 20 Head Start preschool teachers were asked about their psychological job attitudes. The analyses indicated that preschool teachers' job attitudes were influenced by the amounts and types of support they received regarding their organizational regulations, workplace relationships, and the structural quality of their classrooms, with preschool teachers requiring the most support from their co-teacher and their center director, as well as for children with behavioral problems, and the time needed to complete their paperwork.

    Literature review shows that fathers are still not receiving the support they want and need from Swedish child health professionals2016In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 105, no 9, p. 1014-1023Article, review/survey (Refereed)
    Abstract [en]

    Sweden has a reputation for gender equality, and its child health services seek to support both parents. However, this meta-ethnographic analysis of 62 studies from 2000 to 2015 covering prenatal clinics, labour and birth wards, postnatal wards and child health centres found programmes had not been designed around paternal needs. Therefore, despite the policy change nearly 50 years ago to include both parents, fathers were still not fully accepted and supported. ConclusionTo provide fathers in Sweden with greater support throughout the child health field, organisational changes should be considered, as this could provide further beneficial outcomes for children, families and society.

    Aims and objectives. To explore the needs of and support given to lesbian, gay, bisexual, transgendered and inter-sex parents within the Nordic child health field. Background. The number of lesbian, gay, bisexual, transgendered and inter-sex parents is growing around the world. However, they face fear, discrimination and heteronormativity within the child health field. The Nordic countries (Sweden, Norway, Denmark, Finland and Iceland) rank as the most gender equal countries in the world; therefore, they may support lesbian, gay, bisexual, transgendered and inter-sex parents to a greater extent. Design. Systematic literature review and meta-synthesis. Method. A systematic search was conducted for lesbian, gay, bisexual, transgendered and inter-sex parents' experiences in the child health field, which consists of prenatal, labour and birth, postnatal and child health clinics, using PubMed, PsychInfo, Sociological Abstracts and CINAHL, as well as searching the grey literature, from 2000-2015. Ten articles were included. A quality assessment and a meta-synthesis of the articles were performed. Results. Nearly all studies were qualitative, and most articles had at least one area of insufficient reporting. Only two countries, Sweden and Norway, had lesbian, gay, bisexual, transgendered and inter-sex parents reporting on the child health field. However, gay, bisexual, transgender and inter-sex parents' perspectives were nonexistent in the literature; therefore, the results all relate to same-sex mothers. Five themes were found: Acceptance of Same-sex Mothers, Disclosing Sexual Orientation, Heteronormative Obstacles, Co-mothers are Not Fathers, and Being the Other Parent. Conclusions. Same-sex mothers are generally accepted within the Nordic child health field, but they still face overt and covert heteronormative obstacles, resulting in forms of discrimination and fear. Co-mothers feel invisible and secondary if they are not treated like an equal parent, but feel noticed and important when they are given equal support. Relevance to clinical practice. Changes at the organisational and personnel levels can be made to better support same-sex mothers and co-mothers. Recognising both parents benefits the whole family.

    Swedish child health nurses treat fathers more equally in 2014 than 2004, but mothers remain their primary focus2017In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 106, no 8, p. 1302-1308Article in journal (Refereed)
    Abstract [en]

    Aim: This study focused on Swedish child health nurses' attitudes and the support they provided to fathers and mothers, highlighting changes from 2004 to 2014. Method: In 2014, 363 child health nurses in Stockholm County completed a 23-item questionnaire, similar to the questionnaire by Massoudi et al. in 2004, on their attitudes and the support they gave to fathers and mothers. Analyses were completed using chi-square tests of nurses' attitudes and support to fathers and mothers, and the results from the 2004 and 2014 studies were compared. Results: In 2014, the vast majority of nurses fully agreed that it was important to have close contact with both parents, but more than two-thirds did not feel they had the same competencies for mothers and fathers and three quarters found it complicated to support both parents. The majority viewed fathers more equally in 2014 than in 2004 and although they did provide more support to both parents, mothers in 2014 still received more support than fathers. Conclusion: While Swedish child health nurses viewed fathers as more equal to mothers in 2014 than 2004, mothers still received the majority of the parenting support.

    Association of Cardiovascular Burden with Mobility Limitation among Elderly People: A Population-Based Study2013In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 8, no 5, article id e65815Article in journal (Refereed)
    Abstract [en]

    Background: Cardiovascular risk factors (CRFs) such as smoking and diabetes have been associated with mobility limitations among older adults. We seek to examine to what extent individual and aggregated CRFs and cardiovascular diseases (CVDs) are associated with mobility limitation. Methods: The study sample included 2725 participants (age >= 60 years, mean age 72.7 years, 62% women) in the Swedish National Study on Aging and Care in the Kungsholmen district of central Stockholm, Sweden, who were living either at their own home or in institutions. Data on demographic features, CRFs, and CVDs were collected through interview, clinical examination, self-reported history, laboratory tests, and inpatient register. Mobility limitation was defined as walking speed <0.8 m/s. Data were analyzed using multiple logistic models controlling for potential confounders. Results: Of the 2725 participants, 581 (21.3%) had mobility limitation. The likelihood of mobility limitation increased linearly with the increasing number of CRFs (i.e., hypertension, high C-reactive protein, obesity, diabetes and smoking) (p for linear trend<0.010) and of CVDs (i.e., ischemic heart disease, atrial fibrillation, heart failure and stroke) (p for linear trend<0.001). There were statistical interactions of aggregated CRFs with age and APOE epsilon 4 allele on mobility limitation (p(interaction)<0.05), such that the association of mobility limitation with aggregated CRFs was statistically evident only among people aged <80 years and among carriers of the APOE epsilon 4 allele. Conclusion: Aggregations of multiple CRFs and CVDs are associated with an increased likelihood of mobility limitation among older adults; however the associations of CRFs with mobility limitation vary by age and genetic susceptibility.

    Can chronic multimorbidity explain the age-related differences in strength, speed and balance in older adults?2012In: Aging Clinical and Experimental Research, ISSN 1594-0667, E-ISSN 1720-8319, Vol. 24, no 5, p. 480-489Article in journal (Refereed)
    Abstract [en]

    Background and aims: It is known that physical performance declines with age in general, however there remains much to be understood in terms of age-related differences amongst older adults across a variety of physical components (such as speed, strength and balance), and particularly in terms of the role played by multimorbidity of chronic diseases. We aimed to detect the age-related differences across four components of physical performance and to explore to what extent chronic diseases and multimorbidity may explain such differences. Methods: We analyzed cross-sectional data from a population-based sample of 3323 people, aged 60 years and older from the SNAC-K study, Stockholm, Sweden. Physical performance was assessed by trained nurses using several tests (grip strength, walking speed, balance and chair stands). Clinical diagnoses were made by the examining physician based on clinical history and examination. Results: Censored normal regression analyses showed that the 72- 90+ year-old persons had 17-40% worse grip strength, 44-86% worse balance, 30-86% worse chair stand score, and 21-59% worse walking speed, compared with the 60-66 year-old persons. Chronic diseases were strongly associated with physical impairment, and this association was particularly strong among the younger men. However, chronic diseases explained only some of the age-related differences in physical performance. When controlling for chronic diseases in the analyses, the age-related differences in physical performance changed 1-11 percent. Conclusion: In spite of the strong association between multimorbidity and physical impairment, chronic morbidities explained only a small part of the age-related differences in physical performance.

    Education-related differences in physical performance after age 60: a cross-sectional study assessing variation by age, gender and occupation2013In: BMC Public Health, ISSN 1471-2458, E-ISSN 1471-2458, Vol. 13, p. 641-Article in journal (Refereed)
    Abstract [en]

    Background: Having a low level of education has been associated with worse physical performance. However, it is unclear whether this association varies by age, gender or the occupational categories of manual and non-manual work. This study examined whether there are education-related differences across four dimensions of physical performance by age, gender or occupational class and to what extent chronic diseases and lifestyle-related factors may explain such differences. Methods: Participants were a random sample of 3212 people, 60 years and older, both living in their own homes and in institutions, from the Swedish National Study on Aging and Care, in Kungsholmen, Stockholm. Trained nurses assessed physical performance in grip strength, walking speed, balance and chair stands, and gathered data on education, occupation and lifestyle-related factors, such as physical exercise, body mass index, smoking and alcohol consumption. Diagnoses of chronic diseases were made by the examining physician. Results: Censored normal regression analyses showed that persons with university education had better grip strength, balance, chair stand time and walking speed than people with elementary school education. The differences in balance and walking speed remained statistically significant (p < 0.05) after adjustment for chronic diseases and lifestyle. However, age-stratified analyses revealed that the differences were no longer statistically significant in advanced age (80+ years). Gender-stratified analyses revealed that women with university education had significantly better grip strength, balance and walking speed compared to women with elementary school education and men with university education had significantly better chair stands and walking speed compared to men with elementary school education in multivariate adjusted models. Further analyses stratified by gender and occupational class suggested that the education-related difference in grip strength was only evident among female manual workers, while the difference in balance and walking speed was only evident among female and male non-manual workers, respectively. Conclusions: Higher education was associated with better lower extremity performance in people aged 60 to 80, but not in advanced age (80+ years). Our results indicate that higher education is associated with better grip strength among female manual workers and with better balance and walking speed among female and male non-manual workers, respectively.

    Vascular Risk Factor Burden, Atherosclerosis, and Functional Dependence in Old Age: A Population-Based Study2014In: International Journal of Behavioral Medicine, ISSN 1070-5503, E-ISSN 1532-7558, Vol. 21, no 4, p. 597-604Article in journal (Refereed)
    Abstract [en]

    Vascular risk factors such as hypertension and obesity have been associated with physical limitations among older adults. The purpose of this study is to examine whether individual and aggregated vascular risk factors (VRFs) are associated with functional dependence and to what extent carotid atherosclerosis (CAS) or peripheral artery disease (PAD) may mediate the possible associations of aggregated VRFs with functional dependence. This cross-sectional study included 1,451 community-living participants aged a parts per thousand yen60 years in the Confucius Hometown Aging Project of China. Data on demographic features, hypertension, high total cholesterol, obesity, smoking, physical inactivity, diabetes, CAS, PAD, and cardiovascular diseases (CVDs) were collected through an interview, a clinical examination, and laboratory tests. Functional dependence was defined as being dependent in at least one activity in the personal or instrumental activities of daily living. Data were analyzed using multiple logistic models controlling for potential confounders. We used the mediation model to explore the potential mediating effect of CAS and PAD on the associations of aggregated VRFs with functional dependence. Of the 1,451 participants, 222 (15.3 %) had functional dependence. The likelihood of functional dependence increased linearly with increasing number of VRFs (hypertension, high total cholesterol, abdominal obesity, and physical inactivity) (p for trend < 0.002). Mediation analysis showed that controlling for demographics and CVDs up to 11 % of the total association of functional dependence with clustering VRFs was mediated by CAS and PAD. Aggregation of multiple VRFs is associated with an increased likelihood of functional dependence among Chinese older adults; the association is partially mediated by carotid and peripheral artery atherosclerosis independently of CVDs.

    Physical activity in people age 80 years and older as a means of counteracting disability, balanced in relation to frailty2012In: Journal of Aging and Physical Activity, ISSN 1063-8652, E-ISSN 1543-267X, Vol. 20, no 3, p. 317-331Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to describe experiences of physical activity, perceived meaning, and the importance of and motives and barriers for participation in physical activity in people 80 years of age and older. A qualitative design with focus-group methodology was used. The sample consisted of 20 community-living people age 80-91 yr. Data analyses revealed 4 themes: physical activity as a part of everything else in life, joie de vivre, fear of disease and dependence, and perceptions of frailty. Our results suggest that physical activity was not seen as a separate activity but rather as a part of activities often rated as more important than the physical activity itself. Thus, when designing physical activity interventions for elderly people, health care providers should consider including time for social interaction and possibilities to be outdoors. Moreover, assessment of physical activity levels among elderly people should include the physical activity in everyday activities.

    Sex Differences in the Association Between Pain and Injurious Falls in Older Adults: A Population-Based Longitudinal Study2017In: American Journal of Epidemiology, ISSN 0002-9262, E-ISSN 1476-6256, Vol. 186, no 9, p. 1049-1056Article in journal (Refereed)
    Abstract [en]

    We investigated whether there are sex differences in the association between pain and incident injurious falls. A total of 2,934 people (ages >= 60 years) from the population-based Swedish National Study on Aging and Care in Kungsholmen (2001-2004) participated. Participants were followed up for 3 and 10 years for falls leading to hospitalization or outpatient care. Data were analyzed with flexible parametric survival models that adjusted for potential confounders. During the first 3 years of follow-up, 67 men and 194 women experienced an injurious fall, and over 10 years of follow up, 203 men and 548 women experienced such a fall. In men, the presence of pain, having pain that was at least mild, having pain that affected several daily activities, and having daily pain all significantly increased the likelihood of incurring an injurious fall during the 3-year follow-up period. The multivariate-adjusted hazard ratios ranged from 1.78 (95% confidence interval: 1.00, 3.15) for the presence of pain to 2.89 (95% confidence interval: 1.41, 5.93) for several daily activities' being affected by pain. Results for the 10-year follow-up period were similar. No significant associations were detected in women. Although pain is less prevalent in men than in women, its impact on risk of injurious falls seems to be greater in men.

    Cognitive and Physical Function in Relation to the Risk of Injurious Falls in Older Adults: A Population-Based Study2017In: The journals of gerontology. Series A, Biological sciences and medical sciences, ISSN 1079-5006, E-ISSN 1758-535X, Vol. 72, no 5, p. 669-675Article in journal (Refereed)
    Abstract [en]

    Background: We aimed to quantify the independent effect of cognitive and physical deficits on the risk of injurious falls, to verify whether this risk is modified by global cognitive impairment, and to explore whether risk varies by follow-up time. Methods: Data on 2,495 participants (>= 60 years) from the population-based Swedish National Study on Aging and Care in Kungsholmen (SNAC-K) study were analyzed using flexible parametric survival models. Two cognitive domains (processing speed and executive function) were assessed with standard tests. Physical function tests included balance (one-leg-stands), walking speed, chair stands, and grip strength. Global cognition was assessed using the Mini-Mental State Examination. Results: A total of 167 people experienced an injurious fall over 3 years of follow-up, 310 over 5 years, and 571 over 10 years. Each standard deviation worse balance, slower walking speed, and longer chair stand time increased the risk of injurious falls over 3 years by 43%, 38%, and 23%, respectively (p<.05). Each standard deviation worse processing speed and executive function was significantly associated with 10% increased risk of injurious falls over 10 years (p<.05). In stratified analyses, deficits in physical functioning were associated with injurious falls only in people with cognitive impairment, whereas deficits in processing speed and executive function were associated with injurious falls only in people without cognitive impairment. Conclusions: Deficits in specific cognitive domains, such as processing speed and executive function, appear to predict injurious falls in the long term. Deficits in physical function predict falls in the short term, especially in people with global cognitive impairment.

    Impact of tooth loss on walking speed decline over time in older adults: a population-based cohort study2017In: Aging Clinical and Experimental Research, ISSN 1594-0667, E-ISSN 1720-8319, Vol. 29, no 4, p. 793-800Article in journal (Refereed)
    Abstract [en]

    Background

    Tooth loss has been linked to poor health such as chronic diseases and mobility limitations. Prospective evidence on the association between tooth loss and walking speed decline is however lacking.

    Aims

    To examine the impact of tooth loss on walking speed over time and explore whether inflammation may account for this association.

    Methods

    This study included 2695 persons aged 60 years and older, who were free from severe mobility limitation at baseline. Information on dental status was assessed through self-report during the nurse interview at baseline. Walking speed baseline and at 3- and 6-year follow-ups was assessed when participants walked at their usual pace. Covariates included age, sex, education, lifestyle-related factors, and chronic diseases. Blood samples were taken, and C-reactive protein (CRP) was tested.

    Results

    At baseline, 389 (13.1 %) participants had partial tooth loss and 204 (6.9 %) had complete tooth loss. Mixed-effects models showed that tooth loss was associated with a greater decline in walking speed over time after adjustment for lifestyle-related factors and chronic diseases (p = 0.001 for interaction between time and tooth loss on walking speed decline); however, when further adjusting for inflammation (CRP), the association was attenuated and no longer significant.

    Conclusion

    Tooth loss was associated with an accelerated decline in walking speed in older adults. Inflammation may play a role in the association between tooth loss and walking speed decline.

    Walking speed, processing speed, and dementia: a population-based longitudinal study.2014In: The journals of gerontology. Series A, Biological sciences and medical sciences, ISSN 1079-5006, E-ISSN 1758-535X, Vol. 69, no 12, p. 1503-1510Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Slow walking speed has been shown to predict dementia. We investigated the relation of walking speed, processing speed, and their changes over time to dementia among older adults.

    METHODS: This study included 2,938 participants (age 60+ years) in the population-based Swedish National study on Aging and Care in Kungsholmen, Sweden, who were free from dementia and severe walking impairment at baseline. Walking speed was assessed with participants walking at their usual pace and processing speed was defined by a composite measure of standard tests (digit cancellation, trail making test-A, pattern comparison). Dementia at 3- and 6-year follow-ups was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-IV criteria.

    RESULTS: Of the 2,232 participants who were reassessed at least once, 226 developed dementia. Logistic regression models showed that each standard deviation slower baseline walking speed or decline in walking speed over time increased the likelihood of incident dementia (odds ratios 1.61, 95% confidence interval [CI] 1.31-1.98; and 2.58, 95% CI 2.12-3.14, respectively). Adjustment for processing speed attenuated these associations (odds ratios 1.26, 95% CI 1.01-1.58 and 1.76, 95% CI 1.33-2.34). Mixed-effects models revealed statistical interactions of time with dementia on change in walking and processing speed, such that those who developed dementia showed accelerated decline. At baseline, poorer performance in processing speed, but not in walking speed, was observed for persons who developed dementia during the study period.

    CONCLUSIONS: Processing speed may play an important role for the association between walking speed and dementia. The slowing of walking speed appears to occur secondary to slowing of processing speed in the path leading to dementia.

    Anisotropic phase diagram and superconducting fluctuations of single-crystalline SmFeAsO(0.85)F(0.15)2011In: Physical Review B. Condensed Matter and Materials Physics, ISSN 1098-0121, E-ISSN 1550-235X, Vol. 83, no 10, p. 100513-Article in journal (Refereed)
    Abstract [en]

    We report on the specific-heat determination of the anisotropic phase diagram of single crystals of optimally doped SmFeAsO(1-x)F(x). In zero field, we find a clear cusplike anomaly in C/T with Delta C/T(c) = 24 mJ/mol K(2) at T(c) = 49.5 K. In magnetic fields along the c axis, pronounced superconducting fluctuations induce broadening and suppression of the specific-heat anomaly which can be described using three-dimensional lowest-Landau-level scaling with an upper critical field slope of -3.5 T/K and an anisotropy of Gamma = 8. The small value of Delta C/T(c) yields a Sommerfeld coefficient gamma similar to 8 mJ/mol K(2), indicating that SmFeAsO(1-x)F(x) is characterized by a modest density of states and strong coupling.

    The Stabilisation of Model Parameter Estimates from Repeated Surveys with Rare Observations2013In: Australian & New Zeeland Journal of Statistics, ISSN 1467-842X, Vol. 55, no 4, p. 471-491Article in journal (Refereed)
    Abstract [en]

    In many surveys, the domains of study are small and the samples that carry information on a domain can be very small indeed. If the survey is conducted repeatedly there is often a high degree of overlap in samples over time. We show how to use the richness of information over time to compensate for the paucity of cross-sectional information. We propose a model-based estimator of the population total based on stabilised parameter estimates that combine information from different survey periods that are adjacent in time.  The motivating example for this research has been the ProdCom survey as implemented in the UK.

    Non invasive in situ measurement gas diffusivity of topsoil2012In: Soil Science Society of America Journal, ISSN 0361-5995, E-ISSN 1435-0661, Vol. 76, no 6, p. 1992-1998Article in journal (Refereed)
    Abstract [en]

    A commonly accepted method to measure the in situ gas diffusivity of topsoil is based on the diffusion of a test gas from an open-bottomed chamber that is inserted a few centimeters into the soil. The aim of this study is to develop an easy-to-use approach to determine the gas diffusivity of topsoil at sites where the chamber cannot be inserted into the soil. In the existing method, the diffusion of gas into the soil is a quasi-one-dimensional problem with an analytical solution for gas concentration in the chamber as a function of time t. This one-dimensionality is no longer given in the case of a chamber placed on top of the soil. In the newly suggested method, simulated time series of gas concentrations in a chamber inserted into the soil (Case 1) were compared to those for a chamber placed on top of the soil (Case 2), with equal gas diffusion coefficients for the soil, D-s. We determined a relationship that can be used to convert the chamber concentration for a given D-s at each t in Case 2 to Case 1. The values of D-s can be found iteratively. The method was validated using D-s values different from those used to calculate the function parameters. Practical field measurements of gas diffusivity were also conducted, which show that, on average, both methods yield the same results for an individual site.

    Kapitalstruktur: En jämförelse mellan bygg/anläggnings- & bemanningsbranschen2004Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Ett företag kan välja att finansiera sin verksamhet på flera olika sätt, beroende på den specifika risk som är förknippad med respektive bransch, verksamhetsinriktning, konjunkturläge m.m. kan ett företag välja olika kombinationer av eget och lånat kapital beroende på vad som passar bolaget bäst. Det är kombination av eget och lånat kapital som benämns kapitalstruktur, beroende på hur ett företags kapitalstruktur är utformad uppstår olika kapitalkostnader. Ett företags optimala kapitalstruktur brukar benämnas som den sammansättning av skulder och eget kapital som maximerar ett företags värde samtidigt som dess kapitalkostnad minimeras.

    Företagsvärdering: En studie av hur en analytiker använder de värderingsmodeller som existerar på marknaden2005Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen klarlägger skillnaderna mellan de olika värderingsmodellerna och visar vilka som används på marknaden. Detta görs genom att betrakta fyra företag som arbetar med företagsvärderingar. Uppsatsen synliggör även tillvägagångssättet vid en värderingssituation samt åskådliggör de praktiska problemen som uppkommer vid en företagsvärdering. Dessa praktiska problem handlar mycket om att uppskatta variablerna i de respektive modellerna. Uppsatsen försöker också åskådliggöra vad för nytta företagsvärderare har av nyligen presenterade redovisningsrapporter.

    Ecohydrological disturbances associated with roads: Current knowledge, research needs, and management concerns with reference to the tropics2018In: Ecohydrology, ISSN 1936-0584, E-ISSN 1936-0592, Vol. 11, no 3, article id e1881Article, review/survey (Refereed)
    Abstract [en]

    Roads are a pervasive form of disturbance with potential to negatively affect ecohydrological processes. Some of the most rapid growth in road networks is occurring in developing countries, particularly in the tropics, where political agendas are often focused on strengthening the economy, improving infrastructure, bolstering national security, achieving self-sufficiency, and increasing citizen well-being, often at the expense of the environment. We review what is known about road impacts on ecohydrological processes, focusing on aquatic systems, both temperate and tropical. We present seven cases that represent the broader trends of road development and impacts in tropical settings. Many of these process dynamics and impacts are not different from those experienced in temperate settings, although the magnitude of impacts in the tropics may be amplified with intense rainfall and lack of best management practices applied to road construction/maintenance. Impacts of roads in tropical settings may also be unique because of particular organisms or ecosystems affected. We outline a set of best practices to improve road network management and provide recommendations for adopting an agenda of research and road management in tropical settings. Importantly, we call for incorporation of transdisciplinary approaches to further study the effects of roads on ecohydrological processes in the tropics. Specific emphasis should also be placed on collaboration with governments and developers that are championing road development to help identify the drivers of road expansion and thresholds of negative impact, as well as methods of sustainable road construction and maintenance.

    Actin dynamics provides membrane tension to merge fusing vesicles into the plasma membrane2016In: Nature Communications, ISSN 2041-1723, E-ISSN 2041-1723, Vol. 7, article id 12604Article in journal (Refereed)
    Abstract [en]

    Vesicle fusion is executed via formation of an Omega-shaped structure (Omega-profile), followed by closure (kiss-and-run) or merging of the Omega-profile into the plasma membrane (full fusion). Although Omega-profile closure limits release but recycles vesicles economically, Omega-profile merging facilitates release but couples to classical endocytosis for recycling. Despite its crucial role in determining exocytosis/endocytosis modes, how Omega-profile merging is mediated is poorly understood in endocrine cells and neurons containing small similar to 30-300 nm vesicles. Here, using confocal and super-resolution STED imaging, force measurements, pharmacology and gene knockout, we show that dynamic assembly of filamentous actin, involving ATP hydrolysis, N-WASP and formin, mediates Omega-profile merging by providing sufficient plasma membrane tension to shrink the Omega-profile in neuroendocrine chromaffin cells containing similar to 300 nm vesicles. Actin-directed compounds also induce Omega-profile accumulation at lamprey synaptic active zones, suggesting that actin may mediate Omega-profile merging at synapses. These results uncover molecular and biophysical mechanisms underlying Omega-profile merging.

    Decoding Hosing and Heating Effects on Global Temperature and Meridional Circulations in a Warming Climate2018In: Journal of Climate, ISSN 0894-8755, E-ISSN 1520-0442, Vol. 31, no 23, p. 9605-9623Article in journal (Refereed)
    Abstract [en]

    The global temperature changes under global warming result from two effects: one is the pure radiative heating effect caused by a change in greenhouse gases, and the other is the freshwater effect related to changes in precipitation, evaporation, and sea ice. The two effects are separated in a coupled climate model through sensitivity experiments in this study. It is indicated that freshwater change has a significant cooling effect that can mitigate the global surface warming by as much as similar to 30%. Two significant regional cooling centers occur: one in the subpolar Atlantic and one in the Southern Ocean. The subpolar Atlantic cooling, also known as the warming hole, is triggered by sea ice melting and the southward cold-water advection from the Arctic Ocean, and is sustained by the weakened Atlantic meridional overturning circulation. The Southern Ocean surface cooling is triggered by sea ice melting along the Antarctic and is maintained by the enhanced northward Ekman flow. In these two regions, the effect of freshwater flux change dominates over that of radiation flux change, controlling the sea surface temperature change in the warming climate. The freshwater flux change also results in the Bjerknes compensation, with the atmosphere heat transport change compensating the ocean heat transport change by about 80% during the transient stage of global warming. In terms of global temperature and Earth's energy balance, the freshwater change plays a stabilizing role in a warming climate.

    Att arbeta med fonologisk medvetenhet: En kartläggning av en skolas sätt att arbeta med fonologisk medvetenhet i förskoleklass och årskurs ett2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie syftar till att ge en bild av hur arbetet med den fonologiska medvetenheten kan se ut på en svensk skola idag. Idén till detta väcktes av teorier som talade för att musik och rytmik kan påverka den fonologiska medvetenheten på ett positivt sätt, varför eventuell integrering av musik i arbetet särskilt beaktades. Det låg också ett fokus vid vilken nivå av fonologisk medvetenhet som eleverna med svenska som andraspråk befann sig på i förhållande till elever med svenska som modersmål. Studien utfördes på en skola, och bestod av insamling av resultat från ett standardiserat test av fonologisk medvetenhet, ett så kallat fonolektest, samt observationer av arbetet i förskoleklass och årskurs ett och kompletterande intervjuer med klassernas klassföreståndare. Resultaten visar att eleverna på skolan presterade genomsnittligt, eller till och med bättre än så, oavsett modersmål. De visar också att ett stort fokus läggs vid träning av fonologisk medvetenhet i förskoleklassen, medan detta inte längre upplevs som nödvändigt i årskurs ett när eleverna förväntas ha knäckt den alfabetiska koden. I båda årskurserna sker ämnesintegrering mellan svenska och andra teoretiska ämnen, men inte mellan svenska och praktisk-estetiska ämnen.
