- Biodiversity declines in farmland have been attributed to intensification of farming at the field level and loss of heterogeneity at the landscape level. However, farmers are not solely optimizing production; their actions are also influenced by social factors, tradition and interest in nature, which indirectly influence biodiversity but rarely are incorporated in studies of farmland biodiversity. We used social science methods to quantify farmers’ interest in nature on 16 farms with winter wheat fields in central Sweden, and combined this with biodiversity inventories of five organism groups (weeds, carabid beetles, bumblebees, solitary bees, and birds) and estimates of landscape composition andmanagement intensity at the field level.Agricultural intensity,measured as crop density, and farmers’ interest in nature explained variation in biodiversity, measured as the proportion of the regional species richness found on single fields. Interest in nature seemed to incorporate many actions taken by farmers and appeared to be influenced by both physical factors, for example, the surrounding landscape, and social factors, for example, social motivations.This study indicates that conservation of biodiversity in farmland, and design of new agri-environmental subsidy systems, would profit from taking farmers’ interest in nature and its relation to agricultural practices into account.

- Ectomycorrhizal fungi (EMF) are important components of soil microbial communities, and EMF biomass can potentially increase carbon (C) stocks by accumulating in the soils as necromass and producing recalcitrant structures. EMF growth depends on the C allocated belowground by the host trees, and the nutrient limitation on tree growth is expected to influence this allocation. Therefore, studying EMF production and understanding the factors that regulates it in natural soils are important to understand C cycling in forests.Fungal mycelium collected from ingrowth mesh bags is commonly used to estimate EMF biomass, but these measurements might not reflect the total EMF production since turnover rates of the hyphae are not considered. Here we estimated EMF production and turnover in response to P fertilization (applied as superphosphate) in a Norway spruce forest where nitrogen (N) deposition has resulted in phosphorus (P) limitation of plant production by using a combination of mesh bags with different incubation periods and with Bayesian inferences. To test how localized patches of N and P influence EMF production and turnover we amended some bags with a nitrogen source (methylene urea) or P source (apatite). Additionally, the Bayesian model tested the effect of seasonality (time of mesh-bag harvesting) on EMF production and turnover.We found that turnover of EMF was not affected by P fertilization or mesh-bag amendment. P fertilization had a negative effect on EMF production in all the mesh-bag amendments, suggesting a reduced belowground C allocation to the EMF when P limitation is alleviated. Apatite amendment significantly increased EMF biomass production in comparison with the pure quartz bags in the control plots but not in the P-fertilized plots. This indicates that P-rich patches enhance EMF production in P-limited forests, but not when P is not limiting. Urea amendment had a generally positive effect on EMF production, but this was significantly reduced by P fertilization, suggesting that a decrease in EMF production due to the alleviated P limitation will affect N foraging. Seasonality had a significant effect on EMF production, and the differences registered between the treatments were higher during the warmer months and disappeared at the end of the growing season.Many studies highlight the importance of N for regulating belowground C allocation to EMF in northern coniferous forests, but here we show that the P status of the forest can be equally important for belowground carbon allocation to EMF production in areas with high N deposition.

Tidskriftsartikel (refereegranskat)abstract
- På sensommaren 1988 hade man i Skåne ett stort lokalt utbrott med 61 fall av infektioner med Yersinia enterocolitica. DEn kliniska bilden var avsevärt mildare än som brukar rapporteras, med diarré, magsmärtor och feber som dominerande symtom, och endast två fall av svårare komplikationer. Den sannolika smittkällan var mjölk från ett litet mejeri där hygienen inte var den bästa, Utbrottet visar på en av många risker med distribution av industriellt framställda kylda livsmedel.

Urinary incontinence : prevalence, treatment seeking behaviour, experiences, and perceptions among persons with and without urinary leakage
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis is to describe urinary incontinence (UI) from a population perspective and to describe experiences and perceptions of UI from an individual perspective. This includes assessing the prevalence of urinary incontinence as well as describing treatment seeking and experiences of living with UI. A secondary aim was to describe the perception of UI among cultures other than the Swedish mainstream, exemplified in this case by Syrian women living in Sweden. Both quantitative and qualitative methods were used, including questionnaires and interviews. Studies I and II were quantitative studies based on a population-based study. Together with a postal survey on general health and living conditions “Life & Health”, a questionnaire on urinary incontinence was sent out to 15 360 randomly-selected residents aged 18-79 in Orebro County, Sweden. In Study I, UI was found to affect 19%. The majority of the respondents experienced minor problems, and only 18% of those reporting UI wanted treatment. However, there was also a group who reported severe problems, but despite this 42% of them did not want treatment. Study II investigated why people with UI refrain from seeking care and treatment. It was found that the desire for treatment was regulated by the frequency of UI, being restricted from participating in various activities, the degree of inconvenience, and the type of UI. Studies III and IV were both qualitative interview studies, describing older women’s experiences of living with UI (Study III) and Syrian women’s perceptions of UI (Study IV). There were similarities between the results of these two studies; the women described UI as a normal and expected problem, and they knew that the district nurse could prescribe incontinence protections and that treatments existed. In both studies, the women expressed difficulties in making contact with the health care service, while the women who did not speak Swedish (Study IV) also had difficulties due to different communication problems. In conclusion, it is important that health care resources are optimized to identify and meet the needs of those who experience major problems with UI, and that there is awareness of the communication difficulties that can be present in meeting with people who speak other languages. However it is also important not to medicalize those who experience minor problems and who have the desire to manage on their own.

Comparison of steaming and boiling of root vegetables for enhancing carbohydrate content and sensory profile
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Root vegetables have unique techno-functional and nutritional properties however, their use in processed foods is limited to a few species, partially due to a lack of knowledge related to the impact of thermal treatments on the sensory properties. This study investigated the effect of steaming and boiling on the microstructure, mechanical properties, and sensory profile of three model root vegetables with distinct carbohydrate composition: Jerusalem artichoke (Helianthus tuberosus L.), parsnip (Pastinaca sativa), and beetroot (Beta vulgaris). Thermally treated Jerusalem artichoke and parsnip showed higher content of cell wall polysaccharides, particularly β-glucans (e.g. cellulose) and pectic components, compared to raw. Steaming produced more cell shrinkage and loss of cell-cell adhesion than boiling, leading to softer vegetables. Processed beetroot showed loss of cell turgor and drastic softening but not clear changes in overall carbohydrate content. The scores for several flavour and in-mouth attributes were higher for steamed vegetables compared to boiled. Our results give insights on the processability of root vegetables towards products with enhanced sensory and nutritional properties.

Children with cancer : focusing on their fear and on how their fear is handled
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Various fears in children with cancer have previously been identified as a result of studying e.g. symptom experiences, distress and uncertainty within this population. Studies of the meaning the children give to their fear, as well as the handling of their fear seem to be sparse, however. Also, fear has not been an exclusive focus in previous studies. Professionals in clinical practice have pointed to the need for such research, which has prompted the present research work. The overall aim of this thesis was therefore twofold; firstly, the aim was to elucidate fear in children and adolescents with cancer in order to gain an understanding from the perspective of adolescents and parents. Secondly, it was to elucidate parents’ and professionals’ handling of the fear. This in order to gain a deeper understanding of what performances and manners the children and adolescents can face when being fearful. A qualitative descriptive design was adopted in the five included studies. The methods used in the data analysis were phenomenological hermeneutical method (studies I–III) and qualitative content analysis (studies IV–V). In study I six adolescent girls, aged 14–16 years, with experiences of various cancer diagnoses, but now declared fit, were interviewed. The results reveal that they experience their fear as embodied, which in the comprehensive understanding of the results was interpreted as a threat to their personal self, their whole existence. Their fear was seen as a holistic intertwined experience, including fear related to the physical body and to the social self. Also, existential fear was described. Their described experience was interpreted as suffering. Studies II and III share the same data. Fifteen parents of children at various ages with various cancer diagnoses were interviewed in focus groups about their experience of their child’s fear. In study II the result reveals how the parents experienced and understood their child’s fear. The fear was described as a multidimensional phenomenon, which was not always easy to identify. It was contrasted to feelings of unease and to absence of fear. In the comprehensive understanding the fear was interpreted as a suffering, as that was regarded to be what was the common meaning in the narratives. The suffering was interpreted as an ethical demand to the parents to take action. In study III the parents described their actions, i.e. they described how they dealt with the fear. Their actions were described as acting in the best interests of the child, which included striving to make the child feel secure and experience wellbeing, up to a certain point. However, after this point the parents used their parental authority to maintain the child’s physical health rather than trying to prevent or relieve the child’s fear. In the comprehensive understanding the parents’ handling of their child’s fear was interpreted as revealing mercy and as being synonymous with meeting the ethical demand put on them. In study IV ten experienced nurses and physicians were individually interviewed about how they handled fear in children with cancer. The result reveals that the existential issues were dealt with within the relationship with the child, on a sliding scale between closeness and distance, and that the fear related to medical procedures occurred on a continuum between support and lack of support. The various actions involved, and the manner in which these actions were performed, was described. In the observational study (study V) eleven parents and their children as well as eleven health professionals participated. They were observed at children’s routine visits at the outpatient clinic. The aim was to study the interactions related to fear. The result reveals that when children were fearful they expressed this both verbally and non-verbally. The parents’ and professionals’ actions and interactions in these situations were found to be characterized by recognition of the fear or lack of attention to the fear. The findings can contribute to a broadened knowledge on fear in children and adolescents with cancer. Awareness and understanding of the meaning adolescents give to their fear, and furthermore, of the parents’ experience and understanding of their child’s fear can provide tools for interacting with these groups. The findings on how fear is dealt with by the ones children have claimed as important sources for support, can give insights into what the child may face when being fearful. These insights can form the basis for individual, as well as collegial, reflections on what is done when children face fear, how fear is handled on an everyday basis and why it is handled in this way. Such reflections could lead to an ethical awareness of handling fear in children with cancer.
