- The reduction in external phosphorus load to Lake Ringsjön during the 1980s, did not result in improved water transparency during the following ten-year period. Furthermore, a fish-kill in the Eastern Basin of the lake, in addition to a cyprinid reduction programme (biomanipulation; 1988–1992), in contrast to theory, did not lead to any increase in zooplankton biomass or size. This absence of response in the pelagic food chain may have been attributed to the increase in abundance of YOY (0+) fish, following the fish reduction programme. Despite the lack of effect on zooplankton, there was a decrease in phytoplankton biomass, a change in species composition and an increase in water transparency following biomanipulation. In 1989, one year after the fish-kill in Eastern Basin, the Secchi depth (summer mean) increased from 60 cm to 110 cm. In the following years, water transparency increased further, despite an increase in phosphorus loading. An unexpected effect of the biomanipulation was an increase in benthic invertebrate and staging waterfowl abundances, which occurred 2–4 years after fish reduction. Hence, the response in the benthic community following biomanipulation was considerably stronger than in the pelagic community. A likely explanation is that reduction in abundance of the benthic feeding fish species bream (Abramis brama), strongly affected the benthic invertebrate fauna. In this paper, we present what we believe happened in Lake Ringsjön, and which processes are likely to have been important at various stages of the restoration process.

- Regular measurement of prothrombin time as an international normalized ratio PT (INR) is mandatory for optimal and safe use of warfarin. Scandinavian evaluation of laboratory equipment for primary health care (SKUP) evaluated the microINR portable coagulometer (microINR((R))) (iLine Microsystems S.L., Spain) for measurement of PT (INR). Analytical quality and user-friendliness were evaluated under optimal conditions at an accredited hospital laboratory and at two primary health care centres (PHCCs). Patients were recruited at the outpatient clinic of the Laboratory of Medical Biochemistry, St Olavs University Hospital, Trondheim, Norway (n=98) and from two PHCCs (n=88). Venous blood samples were analyzed under optimal conditions on the STA-R((R))Evolution with STA-SPA+reagent (Stago, France) (Owren method), and the results were compared to capillary measurements on the microINR((R)). The imprecision of the microINR((R)) was 6% (90% CI: 5.3-7.0%) and 6.3% (90% CI: 5.1-8.3) in the outpatient clinic and PHCC2, respectively for INR 2.5. The microINR((R)) did not meet the SKUP quality requirement for imprecision 5.0%. For INR amp;lt;2.5 at PHCC2 and at both levels in PHCC1, CV% was 5.0. The accuracy fulfilled the SKUP quality goal in both outpatient clinic and PHCCs. User-friendliness of the operation manual was rated as intermediate, defined by SKUP as neutral ratings assessed as neither good nor bad. Operation facilities was rated unsatisfactory, and time factors satisfactory. In conclusion, quality requirements for imprecision were not met. The SKUP criteria for accuracy was fulfilled both at the hospital and at the PHCCs. The user-friendliness was rated intermediate.

Using paradox theory to understand responses to tensions between service and training in general surgery
- 2018
-
Ingår i: Medical Education. - : Wiley. - 0308-0110. ; 52:3, s. 288-301

Tidskriftsartikel (refereegranskat)abstract
- CONTEXT: The tension between service and training in pressured health care environments can have a detrimental impact on training quality and job satisfaction. Yet the management literature proposes that competing demands are inherent in organisational settings: it is not the demands as such that lead to negative outcomes but how people and organisations react to opposing tensions. We explored how key stakeholders responded to competing service-training demands in a surgical setting that had recently gone through a highly-publicised organisational crisis.METHODS: This was an explanatory case study of a general surgery unit. Public documents informed the research questions and the data were triangulated with semi-structured interviews (n = 14) with key stakeholders. Data coding and analysis were initially inductive but, after the themes emerged, we used a paradox lens to group themes into four contextual dimensions: performing, organising, belonging and learning.RESULTS: Tensions were apparent in the data, with managers, surgeons and trainees or residents in conflict with each other because of different goals or priorities and divergent perspectives on the same issue of balancing service and training (performing). This adversely impacted on relationships across and within groups (belonging, learning) and led to individuals prioritising their own goals rather than working for the 'greater good' (performing, belonging). Yet although relationships and communication improved, the approach to getting a better balance maintained the 'compartmentalisation' of training (organising) rather than acknowledging that training and service cannot be separated.DISCUSSION: Stakeholder responses to the tensions provided temporary relief but were unlikely to lead to real change if the tension between service and training was considered to be an interdependent and persistent paradox. Reframing the service-training paradox in this way may encourage adjusting responses to create effective working partnerships. Our findings add to the body of knowledge on this topic, and will resonate with all those engaged in surgical and other postgraduate training.

Parents' experiences of their child being admitted to a paediatric intensive care unit : a qualitative study–like being in another world
- 2018
-
Ingår i: Scandinavian Journal of Caring Sciences. - : Wiley. - 0283-9318. ; 32:1, s. 363-370
-
Tidskriftsartikel (refereegranskat)abstract
- Background: There is very little research on the parent's experiences of having a child admitted to a paediatric intensive care unit. Identifying and describing ‘such experiences’ could facilitate better parental support from the paediatric intensive care team and help the parents manage a stressful situation. Aims: This study aimed to describe parents' experiences of having their child admitted to a paediatric intensive care unit. Methods: Interviews were conducted with 12 parents whose children had been admitted to a paediatric intensive care unit. A qualitative design was used, and the interviews were analysed based on content analysis. Result: The analysis revealed two categories: ‘being involved’ and ‘being informed’ with seven subcategories: ‘caring for the parents’, ‘security and trust’, ‘altering the parental role’, ‘stress and fear’, ‘the importance of knowing’, ‘interaction in the care process’ and ‘being prepared’. An overarching theme emerged: the experience was ‘like being in another world’. The study concludes that a child's admission to a paediatric intensive care unit is a stressful situation, and for the parents to be able to handle the anxiety and stress, they need to be informed of and involved in their child's care. Conclusions: The parents' experience when their child is admitted to a paediatric intensive care unit is fraught with a range of emotion and fear. There are indications that things such as good information, involvement and a positive experience of the transfer to the paediatric ward reduce the stress and anxiety associated with paediatric intensive care admission. The result of this study could be used as a basis for a post-paediatric intensive care follow-up service for the children and their families.

The invasive Pacific oyster, Crassostrea gigas, in Scandinavian coastal waters: A risk assessment on the impact in different habitats and climate conditions
- 2014

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- A massive invasion of the Pacific oyster, Crassostrea gigas, has occurred in Scandinavia during the last decade. The introduction and dispersal was described through collaboration between scientists from Sweden, Denmark and Norway. This work has been followed up by national activities that clearly visualized the need for a continued collaboration between scientists in the Scandinavian countries, as the bio-invasion is a cross-border issue and management actions then have to be synchronized, and based on a “state of the art” knowledge of the Scandinavian bio-invasion of the species. The risk assessment presented in this report is based on available scientific literature, expert judgments and data collected during a Nordic collaboration project on Pacific oysters in 2011 – 2013.

Trade-offs and synergies in the design of multifunctional wetlands : A scaling issue
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Wetland area in agricultural landscapes has been heavily reduced to gain land for crop production, but in recent years there is increased societal recognition of the negative consequences from wetland loss on nutrient retention, biodiversity and a range of other benefits to humans. The current trend is therefore to re-establish wetlands, often with an aim to achieve the simultaneous delivery of multiple ecosystem services, i.e., multifunctionality. Here we review the literature on key objectives used to motivate wetland re-establishment in temperate agricultural landscapes (provision of flow regulation, nutrient retention, climate mitigation, biodiversity conservation and cultural ecosystem services), and their relationships to environmental properties, in order to identify potential for tradeoffs and synergies concerning the development of multifunctional wetlands. Through this process, we find that there is a need for a change in scale from a focus on single wetlands to wetlandscapes (multiple neighboring wetlands including their catchments and surrounding landscape features) if multiple societal and environmental goals are to be achieved. Finally, we discuss the key factors to be considered when planning for re-establishment of wetlands that can support achievement of a wide range of objectives at the landscape scale.
