  • Meeting the users’ need for knowledge : A concept of a learning domain
  • 2005
  • Ingår i: Allestädes närvarande kunskap. - Stockholm : KTH Datavetenskap och kommunikation. - 9171782281 ; , s. 185-200

    • 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.

  • The sustainable brand equity : a retail study measuring sustainable brand equity
  • 2018
  • Ingår i: Global marketing conference proceedings.
  • 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.

  • Transpulmonary driving pressure during mechanical ventilation-validation of a non-invasive measurement method
  • 2020
  • Ingår i: Acta Anaesthesiologica Scandinavica. - : Wiley. - 0001-5172 .- 1399-6576. ; 64:2, s. 211-215
  • 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
  • Ingår i: The Energy Journal. - 0195-6574 .- 1944-9089. ; 30:3, s. 23-50
  • 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.

  • 2002
  • Ingår i:
  • 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.

  • Disordered Crystal Structure and Anomalously High Solubility of Radium Carbonate
  • 2023
  • Ingår i: Inorganic Chemistry. - 0020-1669 .- 1520-510X. ; 62:30, s. 12038-12049
  • Tidskriftsartikel (refereegranskat)abstract
    • Radium-226 carbonate was synthesized from radium-barium sulfate (226Ra0.76Ba0.24SO4) at room temperature and characterized by X-ray powder diffraction (XRPD) and extended X-ray absorption fine structure (EXAFS) techniques. XRPD revealed that fractional crystallization occurred and that two phases were formed─the major Ra-rich phase, Ra(Ba)CO3, and a minor Ba-rich phase, Ba(Ra)CO3, crystallizing in the orthorhombic space group Pnma (no. 62) that is isostructural with witherite (BaCO3) but with slightly larger unit cell dimensions. Direct-space ab initio modeling shows that the carbonate oxygens in the major Ra(Ba)CO3 phase are highly disordered. The solubility of the synthesized major Ra(Ba)CO3 phase was studied from under- and oversaturation at 25.1 °C as a function of ionic strength using NaCl as the supporting electrolyte. It was found that the decimal logarithm of the solubility product of Ra(Ba)CO3 at zero ionic strength (log10 Ksp0) is −7.5(1) (2σ) (s = 0.05 g·L-1). This is significantly higher than the log10 Ksp0 of witherite of −8.56 (s = 0.01 g·L-1), supporting the disordered nature of the major Ra(Ba)CO3 phase. The limited co-precipitation of Ra2+ within witherite, the significantly higher solubility of pure RaCO3 compared to witherite, and thermodynamic modeling show that the results obtained in this work for the major Ra(Ba)CO3 phase are also applicable to pure RaCO3. The refinement of the EXAFS data reveals that radium is coordinated by nine oxygens in a broad bond distance distribution with a mean Ra-O bond distance of 2.885(3) Å (1σ). The Ra-O bond distance gives an ionic radius of Ra2+ in a 9-fold coordination of 1.545(6) Å (1σ).

  • Novel AR solutions in media : customer perception of augmented reality in media applications – possibilities for new service innovations
  • 2013
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • A project titled ‘Customer Perception of Augmented Reality (AR) in Media Applica-tions – Possibilities for New Service Innovations’was carried out, with participantsfrom all of the Nordic countries. The project addressed the fact that the magazineand newspaper business is set to change dramatically as printed products en-counter two specific challenges: a) increasing competition from other media and b)changes in media-consumption habits caused by growth in the use of smartphonesand tablets, such as instant access and digital delivery. The changing marketenvironment for print-media products also opens new opportunities for using tech-nologies such as AR to create innovative applications and hence add businessvalue. To investigate the opportunities for service development within this area, weconducted a study of the state of the art to review the theoretical concepts relevantfor better understanding of the macro-level societal trends and business potentialof augmented reality for print products. Selected cases of augmented reality forprint products were then presented.The next phase of the project consisted of a Nordic empirical study of user per-ceptions of AR applications. Focus-group interviews were used to collect partici-pants’ statements about the use of AR technology. These statements were thenranked by means of the Q-sort method. Factor-analysis methods were appliedwith the objective of understanding the similarities among participants’ answers.The results indicated that AR was seen as useful, beneficial, attractive, interesting,and fascinating and as possessing the ‘wow’ factor. Some considered AR’s usagetime-consuming, while others deemed it time-saving. Another finding is that stand-ards seem to be lacking both for the user interface and on the business-handlingside. Participants saw AR as offering great possibility for innovation. People wouldlike to try the applications, and they would indeed find time for using them. Expec-tations set for AR applications are high.Stemming from the interview and Q-sort, an innovation workshop was organized forthe 19 industrial and academic partners of the project. The brain storming sessionaimed at producing new innovative service concept ideas of AR in printed media.Thirty four different ideas were generated in the workshop. The industrial partnerswere encouraged to select one idea for further development and produce a pilot.The pilots as well as the development process and experiences where presentedas a part of the end seminar.

    • Hormones released from the pituitary have been shown to regulate the expression of different proteins in the central nervous system. We wanted to examine whether peripheral administration of bovine growth hormone (bGH) regulates the expression of delta-opioid receptor (DOR) in the cerebral cortex and cerebellum. Expression of the DOR protein was quantified using Western blot densitometry. DOR mRNA was quantified with a solution hybridization RNase protection assay. Hypophysectomized (Hx) and untreated normal female rats were included in the study. All Hx rats were hormonally treated with cortisol (400 microg/kg/day) and L-thyroxine (10 microg/kg/day) for 19 days. Hypophysectomy resulted in a threefold increase in cerebral cortex and a twofold increase in cerebellum of the DOR protein compared with normal rats. One subgroup of Hx rats received bGH (1 mg/kg body weight) as a daily subcutaneous injection for 19 days. This treatment normalized the levels of DOR protein in the cerebral cortex and cerebellum. Immunohistochemical experiments showed that GH decreased DOR expression especially in layers II-VI in cerebral cortex and in stratum moleculare in cerebellum. Quantification of DOR mRNA by solution hybridization RNase protection assay corresponded to the DOR protein measurements. We conclude that the expression of DORs in cerebral cortex and cerebellum is regulated by GH.

    • Marketing and sales of goods through the Internet (i.e. e-commerce) is often described as an area of major importance for the future development of the Internet. Today there is a special interest in the Internet as an arena for the marketing and sale of consumer goods. Estimates indicate that there will be a rapid growth of turnover for the consumer goods industry on the Internet during the next five years. At the same time many actors on the e-commerce market have experienced problems in reaching the expected and predicted economic objectives. This may indicate that important strategic factors tied to e-commerce still have to be discovered. This paper examines the structure of the traditional retail trade and the e-commerce market and shows differences and similarities between the two market systems.

  • Konferensbidrag (refereegranskat)abstract
    • The analysis in this paper is based on a hypermedia interface strategy. A broadband portal issued from the concept of the local metaphor (Fidler 1997) has been developed as a prototype. The prototype has been used as a demonstrator and is evaluated in focus group interviews with users and service providers. The prototype represents an example of a true Concurrent Enterprising system since the broadband portal gives independent customers and service providers the opportunity to cooperate and interact by help of a common technological platform.

    • The number of players marketing consumer goods and services on the Internet is steadily increasing.  The original (physical) retailers experience fierce competition from other suppliers who market directly to the consumers. How should physical retailers meet this competition? In this paper we show there are many areas which can complement each other between the physical retail store and the e-store. We concentrate our analyses on three basic retailing activities: building the assortment, providing information about the products offered and finally, providing access to the products as part of the final transaction. We ascertain that it makes sense for traditional retailers to establish electronic retailing as part of their current business to meet the competition. The results are based on an strengths and weaknesses analysis of how the basic retail functions change when performed electronically. This evaluation is made from a consumer perspective, based on extensive empirical data. The paper ends with suggestions on how retailers can improve their e-retailing service to the consumers.

    •   The production and distribution of information in connection with products and services is one of the most important functions in today’s business world. The ability to produce and deliver information to the right place on time is often crucial for the company’s reputation and sales. This paper address questions about how companies can establish a dynamic information system with the help of digital media technology and customisation of information. Customisation of information is a process where information is adapted and distributed on different media platforms. A case study of a manufacturing company with global information activity is presented. The case describes a renewal of the company's information strategy in relation to its customer’s preferences. The case demonstrates how multi-channel publishing, including electronic on-line medias, combined with digital printing can offer efficient tools to reach out to the customers with customized information.

  • From printed matters to information distribution New strategies in the Graphic Arts industry
  • 2004
  • Konferensbidrag (refereegranskat)abstract
    • Since the start of digitalization and the introduction of electronic medias suitable for publishing, i.e., the Internet, the printing industry has been struggling to find business models that can survive under these new conditions. Their main strategy up until now has been to find the niches where traditional printing matter is still unthreatened. Another strategy has been to approach the interactive electronic medias and personalize the printed matter with the help of digital printing presses, e.g., print-on-demand and personalized printing. However, long-term survival will demand a broader perspective. Far-sighted printing companies are therefore developing strategies that radically redefine their business. This paper discusses the reasoning behind the new strategies and presents a case study of a printing company that is transforming its activities from traditional printing into multi-channel production and information distribution.

    •  The paper is about personalization system applications in different kind of settings. The studied systems utilize descriptions of information characteristics to perform content based filtering in order to increase stated business objectives. Data and experiences from action research, covering three different product areas – sports retailing, online newspaper and online recruitment sites, are presented and discussed, as well as the considerations made when developing and adapting a personalization system for each of these areas. Data describing personalization efficiency have been collected through an own-developed method, bifurcation, which makes it possible to compare the behavior of personalized groups with the behavior of an un-personalized control groups. The results show that personalization has a positive influence on the stated business objective – traffic increase.

  • Personalized Printing used as a One-to-One Enabler
  • 2003
  • Ingår i: Building the Knowledge Economy. - 1 58603 3794 ; , s. 329-336
  • Konferensbidrag (refereegranskat)abstract
    • The penetration of digital printers in the graphic arts industry today is rather high. However, only a small percentage of the equipment’s capacity is used for personalized printing. It is instead used for the ordinary production of smaller editions. This means that the primary intention of the technology as a tool to produce personalized material has not been realized. One reason for this is the basic lack of understanding towards the business models that can guide personalized printing and how these models can generate value to the actors on the market. The aim of this paper is to contribute to the basic knowledge of personalized printing as an enabler for a one-to-one information strategy. The question of how personalized printed matter combined with electronically distributed information can be a tool in an information and communication strategy for an industrial manufacturer is also discussed.

  • Teaching e-commerce and marketing communication in higher education
  • 2011
  • Konferensbidrag (refereegranskat)abstract
    • This paper presents lessons learnt from a course aimed at giving students expert knowledge in marketing communication on the Internet. The course is developed on the basis of increased use of digital media channels for marketing communication. The paper discusses methods on developing efficient courses in higher education where the development pace of the subject is high. Today universities try to design higher education courses such that they meet the demands of the working life. One pedagogy aimed at meeting this goal is Situated Learning. Three different pedagogical activities that can be described as Situated Learning have been implemented in this course. 1. Teaching based on practical experience with teachers from outside the university. 2. Students as a teaching resource in the course where their competence can be used. 3. A strategy for course literature aimed at actuality and relevance.

  • Visualisation of individual dopants in a conjugated polymer : sub-nanometre 3D spatial distribution and correlation with electrical properties
  • 2022
  • Ingår i: Nanoscale. - : Royal Society of Chemistry. - 2040-3364 .- 2040-3372. ; 14, s. 15404-15413
  • Tidskriftsartikel (refereegranskat)abstract
    • While molecular doping is ubiquitous in all branches of organic electronics, little is known about the spatial distribution of dopants, especially at molecular length scales. Moreover, a homogeneous distribution is often assumed when simulating transport properties of these materials, even though the distribution is expected to be inhomogeneous. In this study, electron tomography is used to determine the position of individual molybdenum dithiolene complexes and their three-dimensional distribution in a semiconducting polymer at the sub-nanometre scale. A heterogeneous distribution is observed, the characteristics of which depend on the dopant concentration. At 5 mol% of the molybdenum dithiolene complex, the majority of the dopant species are present as isolated molecules or small clusters up to five molecules. At 20 mol% dopant concentration and higher, the dopant species form larger nanoclusters with elongated shapes. Even in case of these larger clusters, each individual dopant species is still in contact with the surrounding polymer. The electrical conductivity first strongly increases with dopant concentration and then slightly decreases for the most highly doped samples, even though no large aggregates can be observed. The decreased conductivity is instead attributed to the increased energetic disorder and lower probability of electron transfer that originates from the increased size and size variation in dopant clusters. This study highlights the importance of detailed information concerning the dopant spatial distribution at the sub-nanometre scale in three dimensions within the organic semiconductor host. The information acquired using electron tomography may facilitate more accurate simulations of charge transport in doped organic semiconductors.

  • Long- term cost of spouses’ informal support for dependent midlife stroke survivors
  • 2017
  • Ingår i: Brain and Behavior. - : Wiley. - 2162-3279. ; 7:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: Stroke is a major global disease that requires extensive care and support from society and relatives. The aim of this study was to identify and quantify the long- term informal support and to estimate the annual cost of informal support provided by spouses to their stroke surviving partner. Method: Data were based on the 7- year follow- up of the Sahlgrenska Academy Study on Ischemic Stroke. One- third of the spouses stated that they provided support to their stroke surviving partner. The magnitude of the support was assessed with a study- specific time- diary and was estimated for independent and dependent stroke survivors based on the scores of the modified Rankin Scale. To deal with skewed data, a two- part econometric model was used to estimate the annual cost of informal support. Result: Cohabitant dyads of 221 stroke survivors aged <70 at stroke onset were in- cluded in the study. Spouses of independent stroke survivors ( n = 188) provided on average 0.15 hr/day of practical support and 0.48 hr/day of being available. Corresponding figures for spouses of dependent stroke survivors ( n = 33) were 5.00 regarding practical support and 9.51 regarding being available. The mean annual cost of informal support provided for independent stroke survivors was estimated at €991 and €25,127 for dependent stroke survivor. Conclusion: The opportunity cost of informal support provided to dependent midlife stroke survivors is of a major magnitude many years after stroke onset and should be considered in economic evaluations of health care.

  • Long-term QALY-weights among spouses of dependent and independent midlife stroke survivors.
  • 2017
  • Ingår i: Quality of Life Research. - : Springer Science and Business Media LLC. - 0962-9343 .- 1573-2649. ; 26:11, s. 3059-3068
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: The aim of this study was to investigate whether the dependency of midlife stroke survivors had any long-term impact on their spouses' QALY-weights. METHOD: Data on stroke survivors, controls, and spouses were collected from the 7-year follow-up of the Sahlgrenska Academy Study on Ischemic Stroke. Health-related quality of life was assessed by the SF-36, and the preference-based health state values were assessed with the SF-6D. Spouses of dependent and independent stroke survivors were categorized according to their scores on the modified Rankin Scale. An ordinary least squares regression analysis was used to evaluate whether the dependency of the stroke survivors had any impact on the spouses' QALY-weights. RESULT: Cohabitant dyads of 247 stroke survivors aged <70 at stroke onset and 245 dyads of controls were included in the study. Spouses of dependent stroke survivors (n = 50) reported a significant lower mean QALY-weight of 0.69 in comparison to spouses of independent stroke survivors (n = 197) and spouses of controls, (n = 245) who both reported a mean QALY-weight of 0.77. The results from the regression analysis showed that higher age of the spouse and dependency of the stroke survivor had a negative association with the spouses' QALY-weights. CONCLUSION: The QALY-weights for spouses of dependent midlife stroke survivors were significantly reduced compared to spouses of independent midlife stroke survivors. This indicates that the inclusion of spouses' QALYs in evaluations of early treatment and rehabilitation efforts to reduce stroke patients' dependency would capture more of the total effect in dyads of stroke survivors.

  • Stroke survivors’ long-term QALY-weights in relation to their spouses’ QALY-weights and informal support: a cross-sectional study
  • 2017
  • Ingår i: Health and Quality of Life Outcomes. - : Springer Science and Business Media LLC. - 1477-7525. ; 15
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Healthcare interventions that have positive effects on the stroke survivors’ health-related quality of Life (HRQoL) and quality-adjusted life-years (QALYs) might also have positive effects for their spouses in terms of improved HRQoL and/or reduced spousal informal support. However, knowle dge about stroke survivors ’ HRQoL and QALY and the consequences for their spouses’ HRQoL and QALY is limited. Therefore, the aim of this study was to describe the HRQoL and QALY-weights in dyads of stroke survivors in comparison with dyads of healthy controls, and to study the relationship between the stroke survivors’ QALY-weights and consequences for spouses in terms of QALY-weight and annual cost of informal support, using a long-term perspective. Methods: Data on stroke survivors, controls, and spouses were collected from the seven-year follow-up of the Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS). HRQoL was assessed by the SF-36, and the preference-based health state values were assessed with the SF-6D. The magnitude of the support was assessed with a study specific time-diary. An ordinary least squares (OLS) regression was used to estimate the association between stroke survivors’ and spouses’ QALY-weights. A two-part econometri c model was used to estimate the association between stroke survivors’ QALY-weights and the time spent and cost of spouses’ informal support. Results: Cohabitant dyads of 248 stroke survivors’ aged <70 at stroke onset and 245 controls were included in the study. Stroke survivors had lower HRQoL in the SF-36 domains physical functioning, physical role, general health, vitality (P <0.001), and social functioning (P = 0.005) in comparison with their cohabitant spouses. There was no significant difference in HRQoL for the dyads of controls. The results from the regression analyses showed that lo wer QALY-weights of the stroke survivors were associated with lower QALY-weights of their spouses and increased annual cost of spousal informal support. Conclusion: Our results show that the QALY-weight s for stroke surv ivors had consequences for their spouses in terms of annual cost of spousal informal support and QALY-weights. Hence, economic evalu ation of interventions that improve the HRQoL of the stroke survivors but ignore the consequences for their spouses may underestimate the value of the intervention.

  • Major oil exporters may profit rather than lose, in a carbon-constrained world.
  • 2007
  • Ingår i: Energy Policy. - : Elsevier BV. - 0301-4215. ; 35:12, s. 6346-6353
  • Tidskriftsartikel (refereegranskat)abstract
    • The Organization of Petroleum Exporting Countries (OPEC) claims compensation for losses in expected oil export revenues due to CO2 mitigation measures in developing countries. These losses are expected for two primary reasons: a reduction in the consumption of oil in importing countries and a reduction in the producer price of oil (taxation in an importing country implies a transfer of rents from producers to consumers). So far, most studies have focused on these two mechanisms and corroborated that revenue losses for OPEC are to be expected. However, there are also mechanisms that may be expected to raise the price of oil products. In a cost-effective regime for dealing with climate change, i.e., a regime in which all or most countries participate and in which the same carbon price is applied on all carbon-emitting activities, the cost of using unconventional oil, or synthetic diesel from coal, will increase even more than the cost of using conventional oil. Given that reserves of conventional oil are expected to dwindle over time, heavy oils and coal to liquids might set the long-run price for liquid fuels, which means that the price of oil would increase beyond the carbon fee; i.e., the rent on conventional oil would increase. We use an energy-economic optimization model to analyze these three mechanisms. We find that the net present value of OPEC revenue from conventional oil increases slightly (at most by 4 percent) with a global CO2 restriction regime. We also consider conditions under which this result does not hold.

    • The tourism industry’s contribution to climate change is significant, especially due to air travel. The purpose of this paper is to explore psychological determinants of more sustainable tourism mobility decision-making. We present the findings from an exploratory study of young travellers, from Australia and Sweden into the links between attitude to anthropogenic climate change (AAcc) and demand for information about the environmental impacts of personal travel; and tourism suppliers’ sustainability orientations. We find AAcc related to a number of key sustainable tourism mobility information demand variables, for example, desire for more information about sustainability on travel companies’ websites, as presented in Table 1. Implications and further research directions are discussed.

  • Konferensbidrag (refereegranskat)abstract
    • The paper is about a personalization system that utilizes descriptions of information characteristics to perform content based filtering in order to increase stated business objectives. Data from almost two million unique visits on the website of one of Sweden’s largest online recruitment services are analyzed. The first time a visitor enters the website, (s)he is destined to the personalization group or to the control group by the bifurcation function. Once belonging to the control group, you will always be exposed to a default, non-personalized content. From this, the effect of personalization has been measured by comparing the behavior of the personalized group with the behavior of the control group. The results show that personalization has a positive influence on the stated business objective – traffic increase.

  • Konferensbidrag (refereegranskat)abstract
    • An important issue in Internet marketing is the possibility of designing autonomous agents that are able to interpret subjective values in goods and services. From the customer's point of view, it is important to evaluate all aspects linked to the product before purchasing, not only easily identified objective parameters such as price. From a marketing perspective, the building of a brand is probably the most efficient way to distinguish a product from those of the competitors. It is therefore important for both customers and marketers to design agents that are able to interpret certain subjective product characteristics when searching for products or services on the Internet. This paper outlines a generic model of an autonomous agent Internet marketing system with a discussion on the possibilities of handling subjective product characteristics.

    • This paper describes a personalization system aiming at one-to-one marketing with the ability to support real-time identification, selection, and content creation where the interaction is performed on a web-based e-commerce platform. The personalization system is capable of controlling and presenting the web site in different shapes to different consumers – controlled bifurcation.  When combined with the tracking of the visitor’s site movements, detailed consumer behavior patterns can be established.One important means has been to create a system that can later on be used in consumer behavior research.  The bifurcation capability means that the system can be used to test the impact of different layouts of the web site – or of different sales offerings – in the same way direct marketing methods work.  This system will be able to present different layouts of the site or offerings to randomized groups of visitors.  Their responses, in the form of movements within the site, purchase frequencies, etc., can then be measured by the system.

    • Following a period of immense expectations for electronic commerce and its future role in buying and selling, the e-commerce business idea almost collapsed during the year 2000 when an image of e-commerce as a failure started to become widely spread. However, there are companies that run a profitable and healthy e-commerce business with no dependence on venture capital. In this paper we present new empirical material from ongoing research of successful e-commerce companies. We compare the service qualities of these companies with the success criteria derived from our previous research on consumers’ evaluation of the e-channel, where we hypothesized that the e-channel should be seen as a complementary channel to the traditional channels. Therefore, the focus in this paper is on multi-channel retailers and their interaction with the consumers. The aim is to identify the qualities that seem to characterize profitable e-commerce activities.

    • The rapid expansion of the infrastructure for broadband communication will soon pave the way for a large supply of content services in broadband systems. This contentcan be distributed with the help of simple and widely spread hardware, e.g. televisions with set-top-boxes. This way the new applications will reach a larger part of the population, even those without computer and Internet experience. This will increase demand for applications and interfaces that are very easy to grasp and use. The focus of this paper is the ease-of-use in ICT applications. It is an elaboration of results from an investigation of design principles in a broadband portal prototype based on the local metaphor.  The prototype has been used as a demonstrator in focus groups using respondents with various computer experiences. In this paper, results from interviews with respondents that lack interest and experience in computing are reported. From the results conclusions can be drawn on how to design an interface that is easy to use for all kinds of people. The findings are summarised in a model, demonstrating the implications of the local metaphor on usability and trust.

  • Ingår i: Nature Materials. - : Springer Science and Business Media LLC. - 1476-4660 .- 1476-1122. ; 19:7, s. 738-744

    • Doping of organic semiconductors is crucial for the operation of organic (opto)electronic and electrochemical devices. Typically, this is achieved by adding heterogeneous dopant molecules to the polymer bulk, often resulting in poor stability and performance due to dopant sublimation or aggregation. In small-molecule donor–acceptor systems, charge transfer can yield high and stable electrical conductivities, an approach not yet explored in all-conjugated polymer systems. Here, we report ground-state electron transfer in all-polymer donor–acceptor heterojunctions. Combining low-ionization-energy polymers with high-electron-affinity counterparts yields conducting interfaces with resistivity values five to six orders of magnitude lower than the separate single-layer polymers. The large decrease in resistivity originates from two parallel quasi-two-dimensional electron and hole distributions reaching a concentration of ∼1013 cm–2. Furthermore, we transfer the concept to three-dimensional bulk heterojunctions, displaying exceptional thermal stability due to the absence of molecular dopants. Our findings hold promise for electro-active composites of potential use in, for example, thermoelectrics and wearable electronics.

  • Toughening of a Soft Polar Polythiophene through Copolymerization with Hard Urethane Segments
  • 2021
  • Ingår i: Advanced Science. - : Wiley. - 2198-3844. ; 8:2
  • Tidskriftsartikel (refereegranskat)abstract
    • Polar polythiophenes with oligoethylene glycol side chains are exceedingly soft materials. A low glass transition temperature and low degree of crystallinity prevents their use as a bulk material. The synthesis of a copolymer comprising 1) soft polythiophene blocks with tetraethylene glycol side chains, and 2) hard urethane segments is reported. The molecular design is contrary to that of other semiconductor-insulator copolymers, which typically combine a soft nonconjugated spacer with hard conjugated segments. Copolymerization of polar polythiophenes and urethane segments results in a ductile material that can be used as a free-standing solid. The copolymer displays a storage modulus of 25 MPa at room temperature, elongation at break of 95%, and a reduced degree of swelling due to hydrogen bonding. Both chemical doping and electrochemical oxidation reveal that the introduction of urethane segments does not unduly reduce the hole charge-carrier mobility and ability to take up charge. Further, stable operation is observed when the copolymer is used as the active layer of organic electrochemical transistors.
