- The necessity of software as stand-alone products, and as central parts of non-traditional software products have changed how software products are developed. It started with the introduction of the agile manifesto and has resulted in a change of how software process improvements (SPI) are conducted. Although there are agile SPI methods and several agile practices for evaluating and improving current processes and ways-of-working, no method or practices for evaluating the backlog exists. To address this gap, the Backlog Assessment Method (BAM) was developed and applied in collaboration with Telenor Sweden. BAM enables agile organizations to assess backlogs, and assure that the backlog items are good-enough for their needs and well aligned with the decision process. The results from the validation show that BAM is feasible and relevant in an industrial environment, and it indicates that BAM is useful as a tool to perform analysis of items in a specific backlog. © The Author(s) 2019.

- Spatial planning using a landscape approach has been recognized as being essential for reconciling ecological, cultural and socioeconomic dimensions in sustainable development (SuD). Although embraced as a concept, there is a lack of planning tools capable of incorporating multi-level, multifunctional and multi-sectoral perspectives, especially in a rural context. The departure point in this paper is the legal requirements for municipal comprehensive planning (MCP) in Sweden and an e-mail survey about incentives, stakeholder involvement, policy integration and implementation in MCP in all 15 Swedish mountain municipalities. The purpose of this explorative study is to examine whether MCP could be a tool in planning for SuD. Results indicate a general lack of resources and a low status of MCP that affect, and even limit, stakeholder involvement, policy integration and implementation. However, legal requirements for MCP are targeted at SuD, and municipal personnel responsible for planning appreciate the potential of MCP. Therefore, there is potential to develop the MCP into an effective landscape planning tool. To accomplish this, the status of an active planning process has to be raised, the mandate of the local planning agency has to be secured, and residents and land users have to be involved throughout the planning process.

- Controlled dehydration of macromolecular crystals can lead to significant improvements in crystalline order, which often manifests itself in higher diffraction quality. Devices that can accurately control the humidity surrounding crystals on a beamline have led to this technique being increasingly adopted as experiments become easier and more reproducible. However, these experiments are often carried out by trial and error, and in order to facilitate and streamline them four European synchrotrons have established a collaboration around the HC1b dehydration device. The MAX IV Laboratory, Diamond Light Source, BESSY II, and the EMBL Grenoble Outstation/ESRF have pooled information gathered from user experiments, and on the use of the device, to propose a set of guidelines for these experiments. Here, we present the status and automation of the installations, advice on how best to perform experiments using the device, and an analysis of successful experiments that begins to show some trends in the type of protocols required by some systems. The dehydration methods shown are applicable to any device that allows control of the relative humidity of the air surrounding a macromolecular crystal.

- Means to measure the temporal evolution following a photo-excitation in conjugated polymers are a key for the understanding and optimization of their function in applications such as organic solar cells. In this paper we study the electronic structure dynamics by direct pump-probe measurements of the excited electrons in such materials. Specifically, we carried out a time-resolved photoelectron spectroscopy (TRPES) study of the polymer PCPDTBT by combining an extreme ultraviolet (XUV) high harmonic generation source with a time-of-flight spectrometer. After excitation to either the 1st excited state or to a higher excited state, we follow how the electronic structure develops and relaxes on the electron binding energy scale. Specifically, we follow a less than 50 fs relaxation of the higher exited state and a 10 times slower relaxation of the 1st excited state. We corroborate the results using DFT calculations. Our study demonstrates the power of TRPES for studying photo-excited electron energetics and dynamics of solar cell materials.

- Allergic rhinitis is a global illness with a well-recognised impact on quality of life and work performance. Comparatively little is known about the extent of its economic impact on society. The TOTALL study estimates the total cost of allergic rhinitis using a sample representing the entire Swedish population of working age. A questionnaire focused on allergic rhinitis was mailed out to a random population of Swedish residents, aged 18-65 years. Health-care contacts, medications, absenteeism (absence from work) and presenteeism (reduced working capacity at work) were assessed, and the direct and indirect costs of allergic rhinitis were calculated. Medication use was evaluated in relation to the ARIA guidelines. In all, 3,501 of 8,001 (44%) answered the questionnaire, and 855 (24%) of these reported allergic rhinitis. The mean annual direct and indirect costs because of allergic rhinitis were €210.3 and €750.8, respectively, resulting in a total cost of €961.1 per individual/year. Presenteeism represented 70% of the total cost. Antihistamines appear to be used in excess in relation to topical steroids, and the use of nasal decongestants was alarmingly high. The total cost of allergic rhinitis in Sweden, with a population of 9.5 million, was estimated at €1.3 billion annually. These unexpectedly high costs could be related to the high prevalence of disease, in combination with the previously often underestimated indirect costs. Improved adherence to guidelines might ease the economic burden on society.

Estimating wolf (Canis lupus) population size from number of packs and an individual based model
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Estimating wildlife population-size is fundamental for wildlife management and conservation. However, making monitoring of population size less resource demanding while still keeping a high monitoring accuracy and precision remains a recurrent challenge. One proposed alternative to count individuals is to instead focus on counting a segment of the population that is easier to monitor but at the same time well informative on total population size. We show how total population size can be estimated from group counts by using an individual-based population model in a social living species. We developed a wolf (Canis lupus) specific Individual Based Model and used Approximate Bayesian Computation (ABC) to fit this population model to the time series of annual number of packs, reproductions and pairs obtained from Scandinavian monitoring data. Model informative priors were obtained with data from collared individuals by the Scandinavian wolf research project. The fitted model was then used to estimate a conversion factor from number of packs to total number of individuals and to number of reproductions. There was a good fit between the retained simulations by ABC and the observed Scandinavian wolf population trajectory. The fitted simulations returned a conversion factor of 8.0 (95% CI = 6.62-10.07) from number of packs to total population size and of 1.0 (95% CI = 0.93-1.12) to number of reproductions in December. A sensitivity analysis revealed that the conversion factor from packs to total population size was positively correlated with pup survival and litter size and negatively correlated with subadult, vagrant and adult survivals. Using an individual based model allowed us to model the full complexity of demographic traits of a social-living species such as the wolf. The flexibility of the model also meant that the conversion factor could be estimated for any month during the year. Our approach to estimate total population size from counts of groups requires having a population model where both individuals and groups are explicitly described and can be applied to other wolf populations and group-living species where counting all individuals over a large area is unfeasible.

Kommunikation i förskolan : förskollärares och barnskötares kommunikation med föräldrar i ett digitaliserat medielandskap
- 2019

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this doctoral thesis is to study communication work among personnel in Swedish pre-schools, with a particular focus on mediated communication with parents. The purpose is also to analyse what roles are given to the professionals in this communication, to identify what subject positions are constructed and to identify how boundaries are managed within the communication practices.The primary theoretical framework of the thesis is social constructivism and symbolic interactionism. The pre-school organisation and identities are regarded as in a perpetual state of becoming and changes in the media landscape are viewed as rearranging the preconditions for communication practices. Technical innovations are regarded as social products at both ends. Results build upon observations in five pre-schools, interviews with 32 pre-school employees and multimodal analysis of communication material directed to parents. Additional interviews and document studies were conducted in the form of a case study, in order to gain knowledge of the implementation of a digital learning platform.The study shows that the communication environments differ between pre-schools, e.g. concerning how and which mediums are used. Several obstacles to communication are identified, of which many (but not all) are related to the socioeconomic status of parents. Within the mediated communication, pre-school personnel to some extent position themselves as experts concerning practical and pedagogical questions, whilst parents are positioned as actors in need of guidance. A major function of mediated communication is assigning parents’ responsibilities in relation to the pre-school, along with norms regarding what constitutes the “good” (pre-school) parent. Boundary work in relation to parents is conducted using different modalities, used for hedging but also for establishing professional positions. Digitalisation appears as a negative force when introduced top-down, without regards to the needs, previous practices and preconditions within a particular pre- school; but as a positive force when initiated by the professionals themselves and when responding to particular needs within specific pre-schools. As expectations on digitalisation in pre-schools increase, questions of preconditions and communication skills grow in prominence.Although expectations on pre-school professionals’ communication skills are high, communication with parents is not sufficiently acknowledged as part of the actual work in pre-schools. A sign of (and reasons for) the under prioritisation of communication work is the uneven and arbitrary preconditions for communicating, in the forms of relevant education, time and technical equipment. The lack of resources can be connected to three issues: A working environment issue (discrepancy between expectations and preconditions), a democratic issue (communication being random rather than planned/ considered) and a professional issue (multimodal communication not reflecting the professional identity that informants strive towards).Communication with parents (and surrounding society) needs to be acknowledged as part of the work in pre-school, and the personnel need to be given the necessary skills and conditions for communication, in order to provide equality of ac- cess to the parents, but also to give personnel the possibilities of communicating about and reflecting the pre-school organisation as they know it.

- Radioembolization (RE) with intra-arterial administration of 90Y microspheres is a promising technique for the treatment of liver metastases from small intestinal neuroendocrine tumors (SI-NET) not amenable to surgery or local ablation. However, studies comparing RE to other loco-regional therapies are lacking. The aim of this randomized study was to compare the therapeutic response and safety after RE and bland hepatic arterial embolization (HAE), and to investigate early therapy-induced changes with diffusion-weighted MRI (DWI-MRI).Eleven patients were included in a prospective randomized controlled pilot study, six assigned to RE and five to HAE. Response according to RECIST 1.1 using MRI or CT at 3 and 6months post-treatment was recorded as well as changes in DWI-MRI parameters after 1month. Data on biochemical tumor response, toxicity, and side effects were also collected.Three months after treatment, all patients in the HAE group showed partial response according to RECIST while none in the RE group did (p=0.0022). After 6months, the response rates were 4/5 (80%) and 2/6 (33%) in the HAE and RE groups, respectively (NS). DWI-MRI metrics could not predict RECIST response, but lower pretreatment ADC(120-800) and larger ADC(0-800) increase at 1month were related to larger decrease in tumor diameter when all tumors were counted.HAE resulted in significantly higher RECIST response after 3months, but no difference compared to RE remained after 6months. These preliminary findings indicate that HAE remains a safe option for the treatment of liver metastases from SI-NET, and further studies are needed to establish the role of RE and the predictive value of MR-DWI.
