The virtual body: the self and the body in Swedish diary blogs There are no bodies on the internet and yet, there are bodies on the internet. This article deals with representations of the ‘virtually physical’ in personal weblogs. To examine the data drawn from 14 weblogs, a qualitative content analysis is made. The results show that the virtual body is widely present in these particular internet settings and that it is most commonly described as female. Moreover, the virtual body is to a large extent a fragmented body that one either takes control over or is controlled by.

Boundaries of belonging: transnational adoption and the significance of origin in Swedish official rhetoric This article explores how the category of ‘transnational adoptees’ in Sweden is constructed in two Official Government Reports (SOU). The article is inspired by poststructuralist perspectives on welfare and social categorization, and draws from a postcolonial and feminist theoretical framework. ‘Transnational adoptees’ as a category is understood as constituted through discourse, and given meaning in different contexts. In the reports, a fundamental importance is attached to the fact that individuals with a background as transnationally adopted have been separated from their birth family and country of birth. It is argued that mental problems and a split identity are consequences to be expected from the separation. (Re)connection to the origin is therefore considered to be crucial for the well-being of the group. The article concludes that this line of reasoning is based on a specific logic of blood and roots, in which ‘transnational adoptees’ are understood as belonging to their countries of birth, rather than Sweden. The logic of blood and roots can be read as a form of racialized othering, but also as a discursive exclusion of ‘transnational adoptees’ from Sweden as an imagined, national community.

Dependency or independence? A qualitative study of how elderly home-help recipients regard having help and support Knowledge on elderly people’s understandings of dependence and independence is relatively scarce even though there is plenty of gerontological research on related topics. Although we know how to define and measure different types of dependency, we know, in fact, very little about how elderly home-help recipients themselves regard their situation in terms of dependency, independence and autonomy. This article aims to shed light on home-help recipients’ understandings of these constructs and on how they make sense of their situation. The analysis is based on 29 semi-structured interviews with people between the ages of 77 and 93. The findings show how these home help recipients differentiate between having help and support and being dependent on other people. Through the separation of aspects of these understandings, such as the reason why they accept help and support and how they regard the situation of being helped and assisted, three ways of regarding the situation have been identified, which stress the variability of the social construction of dependency and independence that these elders uphold. Some home-help recipients construct themselves as independent, others as autonomous and able selves, while a third group construct themselves as powerless.

Patients with chronic kidney disease are at higher risk of developing cardiovascular disease. The complex, interaction between the kidney and the cardiovascular system is incompletely understood, particularly at the early stages of the cardiovascular continuum. The overall aim of this thesis was to clarify novel aspects of the interplay between the kidney and the cardiovascular system at different stages of the cardiovascular continuum; from risk factors such as insulin resistance, inflammation and oxidative stress, via sub-clinical cardiovascular damage such as endothelial dysfunction and left ventricular dysfunction, to overt cardiovascular death. This thesis is based on two community-based cohorts of elderly, Uppsala Longitudinal Study of Adult Men (ULSAM) and Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS). The first study, show that higher insulin sensitivity, measured with euglycemic-hyperinsulinemic clamp technique was associated to improve estimated glomerular filtration rate (eGFR) in participants with normal fasting plasma glucose, normal glucose tolerance and normal eGFR. In longitudinal analyses, higher insulin sensitivity at baseline was associated with lower risk of impaired renal function during follow-up. In the second study, eGFR was inversely associated with different inflammatory markers (C-reactive protein, interleukin-6, serum amyloid A) and positively associated with a marker of oxidative stress (urinary F2-isoprostanes). In line with this, the urinary albumin/creatinine ratio was positively associated with these inflammatory markers, and negatively associated with oxidative stress. In study three, higher eGFR was associated with better endothelial function as assessed by the invasive forearm model. Further, in study four, higher eGFR was significantly associated with higher left ventricular systolic function (ejection fraction). The 5th study of the thesis shows that higher urinary albumin excretion rate (UAER) and lower eGFR was independently associated with an increased risk for cardiovascular mortality. Analyses of global model fit, discrimination, calibration, and reclassification suggest that UAER and eGFR add relevant prognostic information beyond established cardiovascular risk factors in participants without prevalent cardiovascular disease. Conclusion: this thesis show that the interaction between the kidney and the cardiovascular system plays an important role in the development of cardiovascular disease and that this interplay begins at an early asymptomatic stage of the disease process.

The present study is an interpretation of the two myths copied in the Old Babylonian period in which the Sumerian mother goddess is one of the main actors. The first myth is commonly called “Enki and Ninḫursaĝa”, and the second “Enki and Ninmaḫ”. The theoretical point of departure is that myths have society as their referents, i.e. they are “talking about” society, and that this is done in an ideological way. This study aims at investigating on the one hand which contexts in the Mesopotamian society each section of the myths refers to, and on the other hand which ideological aspects that the myths express in terms of power relations. The myths are contextualized in relation to their historical and social setting. If the myth for example deals with working men, male work in the area during the relevant period is discussed. The same method of contextualization is used regarding marriage, geographical points of reference and so on. Also constellations of mythical ideas are contextualized, through comparison with similar constellations in other Mesopotamian myths. Besides the method of contextualization, the power relations in the myths are investigated. According to this latter method, the categories at issue, their ranking, as well as their changed ranking, are noted. The topics of the myths are issues important for the kingship and the country, such as irrigation, trade, health and healing, birth, collective work, artisanry and rivalry. All these aspects are used in order to express what the power relations between the goddess Ninḫursaĝa/Ninmaḫ and the god Enki look like. The relations are negotiated and recalibrated, which leads to the goddess getting a lowered status. Part of the negotiations and recalibrations is gender behavior, which is related to historical developments in society. The present work points to the function of these myths as tools of recalibrating not only deities, but also men and women in society.

Objectives: To translate and evaluate the psychometric properties of the Swedish version of the Fear of Complications Questionnaire. Design: Cross-sectional study design and scale development. Settings: Totally, 469 adults (response rate 63.5%) with Type 1 diabetes completed the questionnaires. Participants were recruited from two university hospitals in Sweden. Participants: Eligible patients were those who met the following inclusion criteria: diagnosed with Type 1 diabetes, diabetes duration of at least 1 year and aged at least 18 years. Methods: The Fear of Complications Questionnaire was translated using the forward-backward translation method. Factor analyses of the questionnaire were performed in two steps using both exploratory and confirmatory factor analysis. Convergent validity was examined using the Hospital Anxiety and Depression Scale and the Fear of Hypoglycaemia Fear Survey. Internal consistency was estimated using Cronbach’s alpha.Results: Exploratory factor analysis supported a two-factor solution. One factor contained three items having to do with fear of kidney-related complications and one factor included the rest of items concerning fear of other diabetes-related complications, as well as fear of complications in general. Internal consistency was high Cronbach’s alpha 0.96. The findings also gave support for convergent validity, with significant positive correlations between measures (r = 0.51 to 0.54). Conclusion: The clinical relevance of the identified two-factor model with a structure of one dominant subdomain may be considered. We suggest, however a one-factor model covering all the items as a relevant basis to assess fear of complications among people with Type 1 diabetes.

We present a new version of the hglm package for fittinghierarchical generalized linear models (HGLM) with spatially correlated random effects. A CAR family for conditional autoregressive random effects was implemented. Eigen decomposition of the matrix describing the spatial structure (e.g. the neighborhood matrix) was used to transform the CAR random effectsinto an independent, but heteroscedastic, gaussian random effect. A linear predictor is fitted for the random effect variance to estimate the parameters in the CAR model.This gives a computationally efficient algorithm for moderately sized problems (e.g. n<5000).

The present thesis focuses on characterisation of microstructure and the resulting mechanical and tribological properties of CVD and PVD coatings used in metal cutting applications. These thin and hard coatings are designed to improve the tribological performance of cutting tools which in metal cutting operations may result in improved cutting performance, lower energy consumption, lower production costs and lower impact on the environment.  In order to increase the understanding of the tribological behaviour of the coating systems a number of friction and wear tests have been performed and evaluated by post-test microscopy and surface analysis. Much of the work has focused on coating cohesive and adhesive strength, surface fatigue resistance, abrasive wear resistance and friction and wear behaviour under sliding contact and metal cutting conditions. The results show that the CVD deposition of accurate crystallographic phases, e.g. α-Al2O3 rather than κ-Al2O3, textures and multilayer structures can increase the wear resistance of Al2O3. However, the characteristics of the interfaces, e.g. topography as well as interfacial porosity, have a strong impact on coating adhesion and consequently on the resulting properties.  Through the deposition of well designed bonding and template layer structures the above problems may be eliminated. Also, the presence of macro-particles in PVD coatings may have a significant impact on the interfacial adhesive strength, increasing the tendency to coating spalling and lowering the surface fatigue resistance, as well as increasing the friction in sliding contacts. Finally, the CVD-Al2O3 coating topography influences the contact conditions in sliding as well as in metal cutting. In summary, the work illuminates the importance of understanding the relationships between deposition process parameters, composition and microstructure, resulting properties and tribological performance of CVD and PVD coatings and how this knowledge can be used to develop the coating materials of tomorrow.
