- In everyday life, many people use the web as a resource for knowledge. In this paper we are investigating the preconditions for a web resource called learning domain. The characteristics of the web resource learning domain can contribute to a reduction of well-known problems with structuring the content in a communicative way and also to contribute to an increased trust of the presented information. In the paper the characteristics of learning domains are described and some examples of web sites with characteristics contiguous to that of a learning domain are discussed. Our conclusions are that web resources with learning domain characteristics can contribute as a knowledge support. The challenge related to learning domains is not a technological one but instead how to arrange the information in such a way that it makes sense for the users.

Konferensbidrag (refereegranskat)abstract
- Aim Research in the Swedish retail sector 2017, shows that 37% of the public in Sweden has attitudes and behavior that make them part of the Lifestyle of Health and Sustainability group (Lohas). Lohas is a method (see Lohas.se) to measure sustainable living in a global context (Swedish Sustainability Ranking 2017). This make Sweden in the forefront. Furthermore, the Swedish government has issued a new law (entered into force in 2017) that demands Swedish companies with more than 250 employees or a certain turnover to annually report their sustainability efforts and how it connects to their business model. This is the background for our study investigating different industry sectors in Sweden. In this environment, retailers such as IKEA, Apoteket, Max Burger, Clas Ohlson, and H&M, followed by others, have gained recognition regarding their strong brands as well as good practice within sustainability. Sustainability has recently become more relevant to study. In Sweden repeated surveys, (2004-2017), have shown that Swedish retailers are perceived as the most reputable and sustainable of all companies. What is the background that makes retailers so trusted and sustainable among the general public and customers in Sweden? The purpose of this paper is to present and analyze the underlying factors which give retailers in Sweden such a high sustainability scores over time i.e. what factors are important to achieve sustainable brand equity in the Swedish retail sector. A detailed comparison will be made of two large surveys carried out in 2016 and 2017.Design/methodology/approach This paper explores the branding framework Customer-Based Brand Equity as well as Points of Difference (POD) and Points of Parity (POP) in a projective retailer sustainability perspective, Keller, Apéria and Georgson (2012). The overall customer brand equity framework is developed by Keller (1993). PODs is defined as unique associations, strong and favorable, linked to a brand. POPs are associations that can be shared with other brands, Keller, Sternthal, and Tybout (2002). Ailawadi and Keller (2004) discuss the importance of measuring retailer brand equity. According to the researchers brand equity has been one of the most challenging and important issues for both academics and managers. The chosen framework and the analysis for the study is the corporate brand level. A sustainability index, developed by Apéria, has been developed and tested during the period 2015-2017. The sustainability index measures four dimensions of sustainability: environment/climate, society/ethics, longterm/future perspective, and openness (see figure 1). The index is inspired by the Triple bottom line approach. The data comes from the Swedish Sustainability Ranking, the largest survey on sustainability in Sweden. More than 18,000 online surveys were carried out in 2016 and 25,000 surveys carried out in 2017. The panelists participating in the survey were recruited in order to be representative of the Swedish general public, age 18-74 years. 190 well-known and visible consumer companies were measured in 2016 and 200 companies and organizations in 2017. These companies were selected because they are well-known, salient and represent important categories from a consumer point of view. Our view of salience is based on Ehrenberg, Barnard and Scriven (1997). A pre-study was carried out in 2015 in order to understand consumer criterias for choice of retailer. In 2016, 32 retailers where measured in a specific retailer frame of reference. 4,225 surveys where carried out among general public who participated in the study. In the 2017 survey, 35 retailers were measured and 3,416 surveys were carried out, also in a retailer frame of reference targeting the general public. All respondents taking part in the study initially ranked companies with product, brand, and sustainability attributes. The respondents ranked these retailers with approximately 35 brand- attitude questions (Likert scale from 1-7). In the second part of the interview each respondent also indirectly, through a projective approach, described the retailer. The perspective of reputation and sustainability metrics has traditionally been used in a strict rational point of view. One example of reputation metrics is the RepTrak model described by Fombrun, Ponzi, and Newburry (2015), and van Riel (2012). Chun and Davies (2004) and J. Aaker (1997) have also discussed corporate character and brand personality from a rational point of view. Ailawadi and Keller (2004) have pointed out that brand personality as an area deserves greater attention from research. The authors of this article argue that a complementary perspective is needed to fully understand how consumers evaluate corporate brands and sustainability and the complexity behind this process. The authors propose to add emotional components in the evaluation, as a complement to the traditional rational view. The proposed way to understand the emotional side of a corporate brand is to use projective techniques (Apéria 2001, Apéria and Back 2004, Keller, Apéria and Georgson 2012). An advantage of projective techniques is that they may elicit responses that respondents may be unwilling or unable to give by traditional interview methods. In this retailer study we used projective techniques in order to explore the more emotional aspects of the retailers.Findings The results from the analyze presents Swedish retailers as representing the most sustainable of all company categories in Sweden. During a period between 2004-2017 the retail category have been in top positions of the Swedish reputation and sustainability ranking, measured in a longitudinal study. Apoteket, The Body Shop and Clas Ohlson have been ranked as number one, one time each. While IKEA has been number one eleven times during the period. During the last two years, 2016 and 2017 IKEA was ranked as number one, based on the sustainability index. The analyze has shown that the highly sustainable retailers operating in the Swedish market primarily are characterized by strong brands as well as strong perceptions of sustainability. An interesting example is the local Swedish fast-food company Max Burgers that strongly outperforms McDonald´s both as a brand as well on sustainability. Successful retailers have different personalities, and archetypes compared with other corporate categories. The analysis reveals that the strongest retailers with a high sustainability index are characterized by having strong brand personalities. Furthermore, the analysis also reveals that the archetypes characterizing these retailers are we-oriented archetypes such as: ordinary/familiar, stable/down to earth, but also the ego-oriented archetype focused/specialist. Examples of retailers with a strong brand personality are IKEA, The Body Shop, Stadium, ICA, Zara and H&M. When we compare the data from the study 2016 with 2017 we see the same results. Our results from both studies indicate that local retailers are more positively evaluated than international. We-orientated brands score higher than ego-orientated. Some retail categories are perceived better than others are. Examples of strong retail categories are pharmacies, furniture, food, and sport stores and weak retailer categories are hamburger restaurants, consumer electronics and telecom stores. However, there is always an opportunity for a retailer to be stronger than the category they represent. One example, earlier mentioned is the local hamburger chain Max Burgers that strongly outperforms international competitors such as Burger King and McDonald´s, when we compare their sustainability indexes. The results indicate that both rational and emotional factors constitute an important part of the Sustainable Brand Equity Model. This new model (see figure 2) has been developed and tested during surveys 2015-2017 by one of the authors as a part of the Swedish Sustainability Ranking. Central components of the model are sustainability indexes, corporate brand personality, brand associations meeting need segments which lead to brand loyalty and trust capital. Finally, our survey shows that retailers needs to be strong in both brand and sustainability. It´s not enough to only excel in sustainability.Research limitations/implications The Sustainability survey was carried out both in 2016 and 2017 in a retailer frame of reference including different retailers from different sectors. The authors recognize that Swedes rank retailers as the most reputable and sustainable category of companies every year. In different countries the general public has different opinions about which companies they found most reputable (Apéria, Simcic Brønn, and Schultz, 2004).Originality/value The authors compares the chosen 32 retailers studied in 2016 with 35 retailers studied in 2017 with the same method. In both surveys we used both rational questions and emotional projective questions in order to understand the retailers in-depth. In both surveys a sustainability index was used in order to rank the retailers.

- Objective:To evaluate the cost-effectiveness of adding endovascular thrombectomy to standard care in patients with acute ischemic stroke.Methods:The cost-effectiveness analysis of endovascular thrombectomy in patients with acute ischemic stroke was based on a decision-analytic Markov model. Primary outcomes from ESCAPE, Extending the Time for Thrombolysis in Emergency Neurological Deficits-Intra-Arterial (EXTEND-IA), Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN), Endovascular Revascularization With Solitaire Device Versus Best Medical Therapy in Anterior Circulation Stroke Within 8 Hours (REVASCAT), and Solitaire with the Intention for Thrombectomy as Primary Endovascular Treatment for Acute Ischemic Stroke (SWIFT PRIME) along with data from published studies and registries were used in this analysis. We used a health care payer perspective and a lifelong time horizon to estimate costs and effects.Results:The model showed that adding thrombectomy with stent retrievers to guideline-based care (including IV thrombolysis) resulted in a gain of 0.40 life-years and 0.99 quality-adjusted life-years along with a cost savings of approximately $221 per patient. The sensitivity analysis showed that the results were not sensitive to changes in uncertain parameters or assumptions.Conclusions:Adding endovascular treatment to standard care resulted in substantial clinical benefits at low costs. The results were consistent throughout irrespective of whether data from ESCAPE, EXTEND-IA, MR CLEAN, REVASCAT, or SWIFT PRIME were used in this model.

Tidskriftsartikel (refereegranskat)abstract
- Background Transpulmonary driving pressure plays an important role in today's understanding of ventilator induced lung injury. We have previously validated a novel non‐invasive method based on stepwise increments of PEEP to assess transpulmonary driving pressure in anaesthetised patients with healthy lungs. The aim of this study was to validate the method in patients who were mechanically ventilated for different diagnoses requiring intensive care. Methods We measured transpulmonary pressure (Ptp) and calculated transpulmonary driving pressure (ΔPtp) in 31 patients undergoing mechanical ventilation in an intensive care unit. Parallel triplicate measurements were performed with the PEEP step method (PtpPSM) and the conventional oesophageal balloon method (Ptpconv). Their agreement was compared using the intraclass correlation coefficient (ICC) and the Bland Altman plot. Result The coefficient of variation for the repeated measurements was 4,3 for ΔPtpPSM and 9,2 for ΔPtpconv. The ICC of 0,864 and the Bland Altman plot indicate good agreement between the two methods. Conclusion The non‐invasive method can be applied in mechanically ventilated patients to measure transpulmonary driving pressure with good repeatability and accuracy comparable to the traditional oesophageal balloon method.

OPEC strategies and oil rent in a climate conscious world
- 2009

Tidskriftsartikel (refereegranskat)abstract
- In the UNFCCC process, energy exporting countries (primarily OPEC) claim compensation for losses in expected oil rent due to CO 2 mitigation measures. However, there are mechanisms that may raise rather than lower the oil rent. If a carbon price is implemented universally, the cost of using oil substitutes such as unconventional oil or synthetic diesel from coal or natural gas will increase even more than the cost of using conventional oil. Here, a dynamic model that takes into account OPEC's dominant position in the world's liquid fuel market is developed in order to analyze these mechanisms. In this model, OPEC is assumed to act as strategic leader while all other liquid fuel producers act as price-takers. We find that the net present value of OPECs conventional oil rent increases by about 5% due to the carbon prices needed to reach stringent CO 2 emission targets. For less ambitious targets, the increase in oil rent could be even higher. An extensive sensitivity analysis is also performed, which corroborates the main result.

- The paper deals with a personalization system that utilizes descriptions of information characteristics to perform content based filtering in order to increase stated business objectives. The paper reports from testing of the personalization system in two commercial implementations, the website of Sweden’s third largest daily newspaper and the website of one of Sweden’s largest online recruitment services for the public sector. The results indicate that personalization has a positive influence on the stated business objective – traffic increase. Further, a personalization configuration that gives a high weight to the customer’s behavior in the ongoing session compared to the behavior in previous sessions was favorable to promote traffic increase.

Konferensbidrag (refereegranskat)abstract
- The paper reports on qualitative case studies of a purposeful sample of e-commerce companies. This is part of ongoing research, aiming at pointing out the qualities that characterize profitable e-commerce activities. The findings are compared with the success criteria derived from previous research on consumers’ evaluation of the e-channel. The paper concludes by discussing the prerequisites for a successful e-business. From our previous research, we have hypothesized that the e-channel should be seen as a complementary channel to the traditional channels. Therefore, we particularly focus on multi-channel retailers.

Net Society. Content Creation in Broadband Systems
- 2000
-
Konferensbidrag (refereegranskat)abstract
- The development of a broadband application which integrates TV, Internet, picture telephones etc has been going on for several years within Telia, Sweden's leading telecom operator. The prototype solutions have been developed from a vision of how the distant communication of the future could function. Results of a qualitative study of how the prototype is perceived by consumers and service providers are presented. Compared to the Internet, the NNS prototype was perceived as being simpler, less confusing, faster to navigate and suited for all kinds of people. This paper has two aims: to provide an inspiration for new applications in a broadband environment, and to indicate problems connected with presenting content in a broadband environment.
