    The Blind Spot: Mind, Body or Matter?

    Using Nick Crossley’s recently published The Social Body. Habit, identity and desire as a starting-point the author questions certain contemporary attempts to overcome dualism (often connected with present-day sociological interest in the body). He argues that they, if committed to materialism, crude or sophisticated, will reproduce dualism. They will end in materialist reductionism, he argues,unless ”knowing” or ”mind”, a no-thing-ness, is recognized as inalienable to reality. This does not, as often assumed, imply ”solipsism” unless one accepts the very dualist presupposition that mind is some-thing ”private”, ”inside” of basically separate selves. Introducing non-dualist traditions outside of the body of academic sociology he presents certain practical forms of inquiry. Directed at or including the very inquirer they do not approach the mind/body-issue as a purely ”theoretical” issue. Mind/body-dualism is further seen as an aspect of the broader dualism of self/other, in its turn the basis for human suffering and unfreedom. He asks at last why sociology, given a certain disciplinary self-understanding, bothers about dualism. He proposes the reason it does might be an unrecognised, academically indecent ”existential” search for ”wholeness” . This “existential” aspect need be accepted, for the “problem of dualism ” to find a solution.

    Short telomere length is associated with impaired cognitive performance in European ancestry cohorts2017In: Translational Psychiatry, ISSN 2158-3188, E-ISSN 2158-3188, Vol. 7, e1100Article in journal (Refereed)
    Abstract [en]

    The association between telomere length (TL) dynamics on cognitive performance over the life-course is not well understood. This study meta-analyses observational and causal associations between TL and six cognitive traits, with stratifications on APOE genotype, in a Mendelian Randomization (MR) framework. Twelve European cohorts (N = 17 052; mean age = 59.2 +/- 8.8 years) provided results for associations between qPCR-measuredTL (T/S-ratio scale) and general cognitive function, mini-mental state exam (MMSE), processing speed by digit symbol substitution test (DSST), visuospatial functioning, memory and executive functioning (STROOP). In addition, a genetic risk score (GRS) for TL including seven known genetic variants for TL was calculated, and used in associations with cognitive traits as outcomes in all cohorts. Observational analyses showed that longer telomeres were associated with better scores on DSST (beta = 0.051 per s. d.-increase of TL; 95% confidence interval (CI): 0.024, 0.077; P = 0.0002), and MMSE (beta = 0.025; 95% CI: 0.002, 0.047; P = 0.03), and faster STROOP (beta = -0.053; 95% CI: -0.087, -0.018; P = 0.003). Effects for DSST were stronger in APOE epsilon 4 non-carriers (beta = 0.081; 95% CI: 0.045, 0.117; P = 1.0 x 10(-5)), whereas carriers performed better in STROOP (beta = -0.074; 95% CI: -0.140, -0.009; P = 0.03). Causal associations were found for STROOP only (beta = -0.598 per s. d.-increase of TL; 95% CI: -1.125, -0.072; P = 0.026), with a larger effect in epsilon 4-carriers (beta = -0.699; 95% CI: -1.330, -0.069; P = 0.03). Two-sample replication analyses using CHARGE summary statistics showed causal effects between TL and general cognitive function and DSST, but not with STROOP. In conclusion, we suggest causal effects from longer TL on better cognitive performance, where APOE epsilon 4-carriers might be at differential risk.

    Forms of interaction

    In this article, the theoretical notion of forms of interaction is introduced, which comprehends how the network and domain structures provide a background for interaction. This general approach is used to discuss how persons can style their identities. Today’s forms of interaction enable people to hide information in interaction with other people. People can, for example, present themselves as individualized, important and successful in interaction with others. This facilitates the emergence of certain values. Especially individualistic values are studied in this article.

    Matematiklärares kompetensutveckling online: policy, diskurs och meningsskapande2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Different forms of professional development online are becoming increasingly common for teachers and the aim of the thesis is to contribute knowledge about online professional development for mathematics teachers and the relationship between professional development, educational policy, and mathematics teaching practice. In the thesis, professional development refers to organized professional development in terms of university courses.

    The thesis consists of four studies, each of which has been presented in the form of an article. The four studies together explore transnational and national policy discourses, meaning-making activities that can be distinguished in online professional development, discourses pertaining to mathematics teaching in the classroom and in the subsequent seminar discussions in the course, and teachers’ experience of professional development online. The different arenas have been explored using the concept of discourse with reference to Fairclough, Gee, and Sfard. The term ”discourse” refers primarily to communication and language in use.

    The result of the studies indicates that the participants have not been offered enough opportunities to reflect on how or whether the use of several concepts and everyday life connections really deepened the students’ understanding of the mathematical content. Moreover, the analysis of the interviews with the participants shows that it was difficult for them to deepen their reflections in the synchronous communication online. There is a lack of reciprocal participation and reflection in the conversation and it is hard for the participants to get an idea of how the others respond to their messages. When a participant has completed his or her message the next speaker continues with a new message and as a result, the communication often takes a new direction instead of allowing in-depth reflection.

    Database for the ampC alleles in Acinetobacter baumannii2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 5, e0176695Article in journal (Refereed)
    Abstract [en]

    Acinetobacter baumannii is a troublesome opportunistic pathogen with a high capacity for clonal dissemination. We announce the establishment of a database for the ampC locus in A. baumannii, in which novel ampC alleles are differentiated based on the occurrence of >= 1 nucleotide change, regardless of whether it is silent or missense. The database is openly accessible at the pubmlst platform for A. baumannii (http://pubmlst.org/abaumannii/). Forty-eight distinctive alleles of the ampC locus have so far been identified and deposited in the database. Isolates from clonal complex 1 (CC1), according to the Pasteur multilocus sequence typing scheme, had a variety of the ampC locus alleles, including alleles 1, 3, 4, 5, 6, 7, 8, 13, 14, 17, and 18. On the other hand, isolates from CC2 had the ampC alleles 2, 3, 19, 20, 21, 22, 23, 24, 26, 27, 28, and 46. Allele 3 was characteristic for sequence types ST3 or ST32. The ampC alleles 10, 16, and 25 were characteristic for CC10, ST16, and CC25, respectively. Our study points out that novel gene databases, in which alleles are numbered based on differences in their nucleotide identities, should replace traditional records that use amino acid substitutions to define new alleles.

    Ethnic groups' knowledge, attitude and practices and Rift Valley fever exposure in Isiolo County of Kenya2017In: PLoS Neglected Tropical Diseases, ISSN 1935-2727, E-ISSN 1935-2735, Vol. 11, no 3, e0005405Article in journal (Refereed)
    Abstract [en]

    Rift Valley fever (RVF) is an emerging mosquito-borne viral hemorrhagic fever in Africa and the Arabian Peninsula, affecting humans and livestock. For spread of infectious diseases, including RVF, knowledge, attitude and practices play an important role, and the understanding of the influence of behavior is crucial to improve prevention and control efforts. The objective of the study was to assess RVF exposure, in a multiethnic region in Kenya known to experience RVF outbreaks, from the behavior perspective. We investigated how communities in Isiolo County, Kenya were affected, in relation to their knowledge, attitude and practices, by the RVF outbreak of 2006/2007. A cross-sectional study was conducted involving 698 households selected randomly from three different ethnic communities. Data were collected using a structured questionnaire regarding knowledge, attitudes and practices that could affect the spread of RVF. In addition, information was collected from the communities regarding the number of humans and livestock affected during the RVF outbreak. This study found that better knowledge about a specific disease does not always translate to better practices to avoid exposure to the disease. However, the high knowledge, attitude and practice score measured as a single index of the Maasai community may explain why they were less affected, compared to other investigated communities (Borana and Turkana), by RVF during the 2006/2007 outbreak. We conclude that RVF exposure in Isiolo County, Kenya during the outbreak was likely determined by the behavioral differences of different resident community groups. We then recommend that strategies to combat RVF should take into consideration behavioral differences among communities.

    Evaluation of Storm Runoff in Wadi Hauran, Western Iraq2017In: Journal of Environmental Hydrology, ISSN 1058-3912, E-ISSN 1996-7918, Vol. 25, 6Article in journal (Refereed)
    Abstract [en]

    Arid and semi arid regions are characterized by low frequency monthly rainfall events and high evaporation during the remaining dry days. Utilizing monthly rainfall means for water balance calculation risks a high error margin. Even when daily rainfall analysis methods are used to evaluate the resulting runoff in a valley course, errors may still be committed when wrong values are assigned to important field elements such as soil cover type, vegetation and land use. Accordingly and when the Soil Conservation Service method (SCS) is applied, single storm rainfall and validation of the estimated Curve Number (CN) value using valley flow measurements is necessary. The evaluation of annual runoff volume in a major valley in the Western Iraqi desert using the SCS method applied to single rainfall storm events and validated by actual historical runoff measurements has revealed that Wadi Hauran would exhibit no runoff flow in one year out of three and that runoff may exceed 69 mm depth in a single water year but the average depth for those years with runoff events is only 11.1 mm

    which amounts to about 64 Mm3 at a location in the center of its catchment area.

    What was Love?: On the Dialectic of Mediation2017In: SIC, ISSN 1847-7755, Vol. 7, no 2Article in journal (Refereed)
    Abstract [en]

    Love has traditionally been understood either as an objective, transcendentforce, or a subjective ability. Through a number of steps,the article argues that both these options have lost their credibility due to changes in the media through which love is performed. First, the article demonstrates how the attempts,in the life sciences, to explain love biologically or physically reproduce a traditional romantic ideology. Then, the implications of the inflation of explicit love declarations, and the consequences of internet dating, are discussed. What these examples amount to is the fact that the medium is brought to the fore. A consequence of this is that the romantic ideology is strengthened, while the premises of romantic love – the autonomous subject and the transcendent objectivity – are weakened or even dissolved.

    Inhibition of the BET family of epigenetic reader proteins: A novel principle for modulating gene expression in IgE-activated mast cells2017In: Immunity, Inflammation and Disease, ISSN 2050-4527, Vol. 5, no 2, 141-150 p.Article in journal (Refereed)
    Abstract [en]

    Introduction: The BET family of bromodomain-containing proteins constitute epigenetic readers that bind to acetylated lysine residues of core histones, thereby translating epigenetic histone marks to effects on gene expression. BET inhibitors are currently emerging as promising therapeutic agents for treatment of various pathological conditions. Here, we explored the potential of using BET inhibition to modulate IgE-mediated responses in mast cells.

    Methods: We assessed the effects of BET inhibitors PFI-1, I-BET151, and I-BET762 on responses downstream of mast cell activation through IgE receptor cross-linking.

    Results: BET inhibitors were neither toxic for mast cells (at doses up to 20M), nor did they prevent IgE-mediated mast cell degranulation. However, we found that BET inhibition, in particular by I-BET151, suppressed IL-6 gene expression and IL-6 protein release in response to IgE-mediated mast cell activation. This was observed in both bone marrow-derived mast cells (BMMCs) and in mature peritoneal-cell derived mast cells. Further analysis showed that BET inhibition also suppressed the expression of a number of additional genes of those that were upregulated by IgE receptor cross-linking, including IL-3, IL-7R, CCR1, and ADAMTS9. However, BET inhibition was selective, i.e., several genes that were upregulated by IgE receptor cross-linking were not affected by BET inhibitors.

    Conclusions: These findings suggest that BET inhibition can interfere with the upregulated expression of selected genes in mast cells activated by IgE receptor cross-linking. Further, our findings introduce the concept of utilizing epigenetic mechanisms for modulating mast cell function in the context of IgE-driven disease.

    Non-Gaussian Resistance Fluctuations in Gold-Nanoparticle-Based Gas Sensors: An Appraisal of Different Evaluation Techniques2017In: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 17, no 4, 757Article in journal (Refereed)
    Abstract [en]

    Volatile organic compounds, such as formaldehyde, can be used as biomarkers in human exhaled breath in order to non-invasively detect various diseases, and the same compounds are of much interest also in the context of environmental monitoring and protection. Here, we report on a recently-developed gas sensor, based on surface-functionalized gold nanoparticles, which is able to generate voltage noise with a distinctly non-Gaussian component upon exposure to formaldehyde with concentrations on the ppm level, whereas this component is absent, or at least much weaker, when the sensor is exposed to ethanol or to pure air. We survey four different statistical methods to elucidate a non-Gaussian component and assess their pros and cons with regard to efficient gas detection. Specifically, the non-Gaussian component was clearly exposed in analysis using level-crossing parameters, which require nothing but a modest computational effort and simple electronic circuitry, and analogous results could be reached through the bispectrum function, albeit with more intense computation. Useful information could be obtained also via the Levy-stable distribution and, possibly, the second spectrum.

    Indigeneidad, descolonización y la paradoja del desarrollismo extractivista en el Estado Plurinacional de Bolivia: Indigeneity, decolonization and the paradox of extractive development in the Plurinational State of Bolivia2017In: Revista Chilena de Derecho y Ciencia Política, ISSN 0718-9389, Vol. 8, no 1, 83-117 p.Article in journal (Refereed)
    Abstract [en]

    Historically, indigenous peoples have been marginalized and oppressed in the Bolivian political economy. During the presidency of Evo Morales, and under the 2009 Constitution, political, economic, social and cultural decolonization has become the central project for the transformation of the State and society. On the one hand, the new Constitution has been classified as one of the most progressive in the world with respect to ethnically defined rights; the indigenous ethical-philosophical principles of Suma Qamaña/Vivir Bien, referring to the harmonious relationship between individuals and nature, have been incorporated into the Constitution. On the other hand, these rights collide with broader social rights (defined by class) and also the rights of the State to extract and market natural resources (especially hydrocarbon extraction and mining) under the banner of redistributive justice, social reforms and the common good. This collision is defined in this study as the paradox of extractivist developmentalism. The article is based on an ethnographic work and problematizes the extractivist dilemma and the tensions between ethnic rights and class rights, thus contributing to debates about indigeneity and the challenges and dilemmas of decolonizing projects.

    Swedish Foreign Fighters in Syria and Iraq: An Analysis of open-source intelligence and statistical data2017Report (Other academic)
    Abstract [en]

    The conflict in Syria and Iraq has resulted in an increase in the number of violent Islamist extremists in Sweden, and a significant increase of people from Sweden travelling to join terrorist groups abroad. Since 2012 it is estimated that about 300 people from Sweden have travelled to Syria and Iraq to join terrorist groups such as the Islamic State (IS) and, to a lesser extent, al-Qaeda affiliated groups such as Jabhat al-Nusra. Even though the foreign fighter issue has been on the political agenda for several years and received considerable media attention, very little is known about the Swedish contingent.

    The purpose of this study is to examine a set of variables of the foreign fighters that have travelled from Sweden to join jihadi terrorist groups in Syria and Iraq in the period of June 2012 to September 2016. Much of the statistical data analysed have been declassified and provided by the Swedish Security Service. The variables examined are: time of travel; age; gender; geographical concentration in Sweden; citizenship and country of origin; average time spent in the conflict area; numbers of individuals killed; number of returnees; number of fighters remaining in the conflict area; social media activities; and the financing of foreign fighters. The analysis includes 267 people that are or have been residents of Sweden.

    36 people (first-time travellers) travelled to Syria or Iraq in 2012, 98 in 2013, 78 in 2014, 36 in 2015, and 5 in 2016. In addition, some of the foreign fighters have travelled back and forth between the conflict area and Sweden. About 80 percent are associated with IS, and more than 30 percent are associated with Jabhat al-Nusra. 76 percent of the foreign fighters are men and 24 percent are women. The amount of women has significantly changed during the period, from “a few” in 2012 to 18 percent in 2013, and constituting about 40 percent of the foreign fighters in the conflict area in 2014 and 2015.

    The average age of the foreign fighters is 26, and there are no significant differences between the average age of men and women. Still, there is a great variation indicating there are very young travellers but also older ones, as the age ranges in a span of 50 years. 18 percent of the travellers (45 people) are 19 or younger, while about 60 percent (154 people) are between the ages of 20 to 29. Very few people above the age of forty seem to travel. The average age does not change over the period.

    A majority of the foreign fighters, an estimated 80 percent, come from four of Sweden’s 21 counties – Västra Götaland, Stockholm, Skåne and Örebro. About one third of the foreign fighters are, or have been, registered in Västra Götaland County, one quarter in Stockholm County, and a tenth in Örebro County and a tenth in Skåne County. More than seventy percent have been residents of an exposed area (socially deprived areas hit by high criminality and low socioeconomic status). There is information that there have been recruiters in some of the areas, but social media may also have played a role in the mobilisation of foreign fighters.

    75 percent of the foreign fighters are Swedish citizens, and 34 percent are born in Sweden. There are geographical concentrations to North Africa, the Horn of Africa and the Middle East, as was seen in the 1990’s and 2000’s. There are also concentrations to the Former Yugoslavia and Russia. 38 countries are represented when analysing country of birth, and most of the foreign fighters have at least one parent with country of birth outside of Sweden.

    The average time spent in the conflict area is 16 months, but there is great variation where some foreign fighters have been there for only a month and others for several years. The average time spent for men is 16 months, while the average for women is 21 months.

    At least 49 people from Sweden have died in Syria or Iraq. All of them are men. The data shows that there are no indications that a larger group of the Swedish foreign fighters has been killed in one single battle. Not more than three people have died during a single month. About half of those who have died are from the Västra Götaland region.

    As of September 2016, 106 foreign fighters (40 percent) had returned to Sweden, while 112 (42 percent) were still in Syria or Iraq. It is estimated that 49 of the 267 (18 percent) have died in the conflict.

    Prostate Cancer Radiation Therapy and Risk of Thromboembolic Events2017In: International Journal of Radiation Oncology, Biology, Physics, ISSN 0360-3016, E-ISSN 1879-355X, Vol. 97, no 5, 1026-1031 p.Article in journal (Refereed)
    Abstract [en]

    Purpose: To investigate the risk of thromboembolic disease (TED) after radiation therapy (RT) with curative intent for prostate cancer (PCa).

    Patients and Methods: We identified all men who received RT as curative treatment (n=9410) and grouped according to external beam RT (EBRT) or brachytherapy (BT). By comparing with an age-and county-matched comparison cohort of PCa-free men (n = 46,826), we investigated risk of TED after RT using Cox proportional hazard regression models. The model was adjusted for tumor characteristics, demographics, comorbidities, PCa treatments, and known risk factors of TED, such as recent surgery and disease progression.

    Results: Between 2006 and 2013, 6232 men with PCa received EBRT, and 3178 underwent BT. A statistically significant association was found between EBRT and BT and risk of pulmonary embolism in the crude analysis. However, upon adjusting for known TED risk factors these associations disappeared. No significant associations were found between BT or EBRT and deep venous thrombosis.

    Conclusion: Curative RT for prostate cancer using contemporary methodologies was not associated with an increased risk of TED.

    Revertant mosaicism repairs skin lesions in a patient with keratitis-ichthyosis-deafness syndrome by second-site mutations in connexin 262017In: Human Molecular Genetics, ISSN 0964-6906, E-ISSN 1460-2083, Vol. 26, no 6, 1070-1077 p.Article in journal (Refereed)
    Abstract [en]

    Revertant mosaicism(RM) is a naturally occurring phenomenon where the pathogenic effect of a germline mutation is corrected by a second somatic event. Development of healthy-looking skin due to RM has been observed in patients with various inherited skin disorders, but not in connexin-related disease. We aimed to clarify the underlying molecular mechanisms of suspected RM in the skin of a patient with keratitis-ichthyosis-deafness (KID) syndrome. The patient was diagnosed with KID syndrome due to characteristic skin lesions, hearing deficiency and keratitis. Investigation of GJB2 encoding connexin (Cx) 26 revealed heterozygosity for the recurrent de novo germline mutation, c. 148G>A, p. Asp50Asn. At age 20, the patient developed spots of healthy-looking skin that grew in size and number within widespread erythrokeratodermic lesions. Ultradeep sequencing of two healthy-looking skin biopsies identified five somatic nonsynonymous mutations, independently present in cis with the p. Asp50Asn mutation. Functional studies of Cx26 in HeLa cells revealed co-expression of Cx26-Asp50Asn and wild-type Cx26 in gap junction channel plaques. However, Cx26-Asp50Asn with the second-site mutations identified in the patient displayed no formation of gap junction channel plaques. We argue that the second-site mutations independently inhibit Cx26-Asp50Asn expression in gap junction channels, reverting the dominant negative effect of the p. Asp50Asn mutation. To our knowledge, this is the first time RM has been reported to result in the development of healthy-looking skin in a patient with KID syndrome.

    Ion trapping by dust grains: Simulation applications to the Enceladus plume2017In: Journal of Geophysical Research - Planets, ISSN 2169-9097, E-ISSN 2169-9100, Vol. 122, no 4, 729-743 p.Article in journal (Refereed)
    Abstract [en]

    Using a particle-in-cell electrostatic simulation, we examine the conditions that allow low-energy ions, like those produced in the Enceladus plume, to be attracted and trapped within the sheaths of negatively charged dust grains. The conventional wisdom is that all new ions produced in the Enceladus plume are free to get picked up (i.e., accelerated by the local E field to then undergo vB acceleration). However, we suggest herein that the presence of submicron-charged dust in the plume impedes this pickup process since the local grain electric field greatly exceeds the corotation E fields. The simulations demonstrate that cold ions will tend to accelerate toward the negatively charged grains and become part of the ion plasma sheath. These trapped ions will move with the grains, exiting the plume region at the dust speed. We suggest that Cassini's Langmuir probe is measuring the entire ion population (free and trapped ions), while the Cassini magnetometer detects the magnetic perturbations associated with pickup currents from the smaller population of free ions, with this distinction possibly reconciling the ongoing debate in the literature on the ion density in the plume.

    The Need for Global Application of the Accountability for Reasonableness Approach to Support Sustainable Outcomes Comment on "Expanded HTA Enhancing Fairness and Legitimacy"2017In: International Journal of Health Policy and Management, ISSN 2322-5939, E-ISSN 2322-5939, Vol. 6, no 2, 115-118 p.Article in journal (Refereed)
    Abstract [en]

    The accountability for reasonableness (AFR) concept has been developed and discussed for over two decades. Its interpretation has been studied in several ways partly guided by the specific settings and the researchers involved. This has again influenced the development of the concept, but not led to universal application. The potential use in health technology assessments (HTAs) has recently been identified by Daniels et al as yet another excellent justification for AFR-based process guidance that refers to both qualitative and a broader participatory input for HTA, but it has raised concerns from those who primarily support the consistency and objectivity of more quantitative and reproducible evidence. With reference to studies of AFR-based interventions and the through these repeatedly documented motivation for their consolidation, we argue that it can even be unethical not to take AFR conditions beyond their still mainly formative stage and test their application within routine health systems management for their expected support to more sustainable health improvements. The ever increasing evidence and technical expertise are necessary but at times contradictory and do not in isolation lead to optimally accountable, fair and sustainable solutions. Technical experts, politicians, managers, service providers, community members, and beneficiaries each have their own values, expertise and preferences, to be considered for necessary buy in and sustainability. Legitimacy, accountability and fairness do not come about without an inclusive and agreed process guidance that can reconcile differences of opinion and indeed differences in evidence to arrive at a by all understood, accepted, but not necessarily agreed compromise in a current context -until major premises for the decision change. AFR should be widely adopted in projects and services under close monitoring and frequent reviews.

    The IoTguide: a business guide to the Internet of Things2017Report (Other academic)
    Abstract [en]

    This research compiles relevant experiences and knowledge about the Internet of Things (ioT) in a clear and concrete guide. It is primarily based on interviews conducted between 2015 and 2017 with firms operating in different industries. While all firms featured in this guide are based in Sweden, we believe that their actions and strategies carry relevevance far beyond the context of any one nation or market. Furthermore, most of the firms that are featured in this guide have a strong international presence, further strengthening their ability to illustrate strategies for creating value by using IoT.  

    By highlighting best practices and showing how firms can apply IoT in dfferent ways while devel- oping new products, services, and business models we show the multiple ways in which IoT can be incorporated into organizational life. Our aim is to inspire firms to draw upon the experience of others and learn from the different cases and insights, starting a discussion on key strategic choices, so that they are better prepared when launching their own IoT venture.

    Governance strategy and costs: board compensation in SwedenIn: Journal of Management and Governance, ISSN 1385-3457, E-ISSN 1572-963XArticle in journal (Refereed)
    Abstract [en]

    Shareholders are not identical, but differ in their objectives and actions. One difference is the level of delegation of the principal functions to the board, which we suggest can be observed through the level of directors’ compensation. We analyze the difference in board compensation through the concept of governance strategy and suggest two distinct categories of shareholder strategies: the company governance strategy and the financial governance strategy. These strategies create different distributions of governance costs, which we separate into principal costs and agency costs. We claim that the financial governance strategy adopts a higher level of delegation, which implies that the principal costs are assumed by the corporation and that agency costs are higher. This in turn can explain the higher compensation for the directors of the board compared to compensation under the company governance strategy. We test our hypothesis using a three-year panel of Swedish listed corporations and find that shareholders pursuing a financial governance strategy are associated with higher levels of board compensation. These findings suggest the existence of differences in governance strategies, reflected in governance costs through board compensation, among different types of shareholders in a corporation.

    Composition dependence of the multifunctional properties of Nd-doped Bi4Ti3O12 ceramics2017In: Journal of materials science. Materials in electronics, ISSN 0957-4522, E-ISSN 1573-482X, Vol. 28, no 11, 7692-7707 p.Article in journal (Refereed)
    Abstract [en]

    Sample preparation, evolution of the crystal structure with Nd content at room temperature, as well as dielectric and magnetic properties of polycrystalline Bi4-xNdxTi3O12 solid solutions (x = 0.0, 0.5, 1.0, 1.5, and 2.0) are reported. These solid solutions were structurally characterized by X-ray powder diffraction using Rietveld refinements. For x <= 1.0, the samples crystallize in an orthorhombic symmetry. The structural data could be refined using the polar orthorhombic space group B2cb. The orthorhombicity decreases with increasing Nd3+ concentration, and a paraelectric tetragonal structure (space group I4/mmm) is stabilized for x > 1. The ferroelectric Curie temperature was found to monotonously decrease with increasing Nd concentration. A polar-to-nonpolar phase transition takes place near x = 1, reflecting the existence of a morphotropic phase boundary between 1.0 < x < 1.5 at room temperature. All samples were found to be paramagnetic down to 5 K, however, the presence of significant antiferromagnetic interaction is inferred from Curie-Weiss analyses of the temperature dependence of the magnetic susceptibility of the doped samples. The effect of Nd3+ substitution on structure-property relationship is discussed and compared to that of other lanthanide cations.

    Exploring design-driven innovation: A study on value creation by SMEs in the Swedish wood products industry2017Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Design-driven innovation, focused on the innovation of product meanings, provides a new perspective to better understand the contribution of design to innovation. Additionally, it enables new opportunities for value creation. At small and medium-sized enterprises (SMEs) in the Swedish wood products industry there is a need for such new value creation in order to remain competitive. However, design-driven innovation is not yet common in this context. Furthermore, there is little research on the innovation of product meanings focused on value creation. Therefore, the aim of this research is to explore value creation through design-driven innovation, in the context of SMEs in the Swedish wood products industry. This research addresses what value might be expected from design-driven innovation, as well as what enables and hinders this value creation. 

    To address the aim, three studies have been conducted which are described in four appended papers. The studies consist of one systematic literature review and two case studies. The findings demonstrate that design-driven innovation contributes to value creation by focusing on product meanings, which intentionally addresses both tangible and intangible needs and therefore increases the perceived value of products. This research identified five facets of design-driven innovation which provide a structure to discuss what enables and hinders value creation. These are: (1) understanding new product meanings, (2) knowledge generation, (3) actors and collaborations, (4) capabilities, and (5) process. The facets can be seen as the origin of both enablers and barriers to value creation through design-driven innovation, depending on how they are addressed. Moreover, this research suggests that whether or not value is created is further influenced by the SMEs, their networks and the context in which they operate.

    Automated Cable Preparation for Robotized Stator Cable Winding2017In: MACHINES, ISSN 2075-1702, Vol. 5, no 2, 14Article in journal (Refereed)
    Abstract [en]

    A method for robotized cable winding of the Uppsala UniversityWave Energy Converter generator stator has previously been presented and validated. The purpose of this study is to present and validate further developments to the method: automated stand-alone equipment for the preparation of the winding cables. The cable preparation consists of three parts: feeding the cable from a drum, forming the cable end and cutting the cable. Forming and cutting the cable was previously done manually and only small cable drums could be handled. Therefore the robot cell needed to be stopped frequently. The new equipment was tested in an experimental robot stator cable winding setup. Through the experiments, the equipment was validated to be able to perform fully automated and robust cable preparation. Suggestions are also given on how to further develop the equipment with regards to performance, robustness and quality. Hence, this work represents another important step towards demonstrating completely automated robotized stator cable winding.

    A fracture mechanics approach to develop high crash resistant microstructures by press hardening2017In: 6th International Conference Hot Sheet Metal Forming of High-Performance Steel CHS2: June 4-7 2017, Atlanta, Georgia, USA : proceedings / [ed] Mats Oldenburg, Braham Prakash, Kurt Steinhoff, Warrendale, PA: Association for Iron & Steel Technology, AIST , 2017, 101-107 p.Conference paper (Refereed)
    Abstract [en]

    Crashworthiness is a relevant engineering property for car parts. However it is not easy to measure at laboratory scale and complex impact tests have to be carried out to determine it. Crash resistance for high strength steel is commonly evaluated in terms of cracking pattern and energy absorption in crashed specimens. Accordingly, the material resistance to crack propagation, i.e. the fracture toughness, could be used to rank crashworthiness. It has been proved in a previous work by the authors, so the measure of fracture toughness, in the frame of fracture mechanics in small laboratory specimens, would allow determining the best microstructure for crash resistance parts. Press hardening offers the possibility to obtain a wide range of microstructural configurations, with different mechanical properties. So the aim of this work is to evaluate the fracture toughness following the essential work of fracture methodology for ferrite-pearlite, bainite, ferrite-bainite, martensite and martensite-bainite microstructures. Results showed that bainitic microstructures have high fracture toughness, similar to TWIP and CP steels, which allows pointing them as potential candidates for obtaining high crash resistance in parts manufactured by press hardening.

    Fracture mechanics based modelling of failure in advanced high strength steels2017In: 6th International Conference Hot Sheet Metal Forming of High-Performance Steel CHS2: June 4-7 2017, Atlanta, Georgia, USA : proceedings / [ed] Mats Oldenburg, Braham Prakash, Kurt Steinhoff, Warrendale, PA: Association for Iron & Steel Technology, AIST , 2017, 15-23 p.Conference paper (Refereed)
    Abstract [en]

    In the last decade, the favorable properties of the press hardening process for advanced high strength steel (AHSS) have increased the demands concerning passenger safety and lightweight design. AHSS show excellent mechanical properties from e.g. tensile test measurements, but it has previously been shown that results from tensile elongation or energy calculation of un-notched and smooth specimen are not appropriate to classify the crash behavior of steel grades. This is because they completely underestimate the post-uniform region from start of necking to failure. Another issue, the mechanical behavior of a notched or cracked component is different than a smooth and un-notched component. If the mechanical behavior in some loading is dominated by crack propagation, it should be rationalized in terms of the materials crack propagation resistance. Therefore, the evolution of the material property that controls crack propagation, i.e. the fracture toughness, is an interesting approach to evaluate loading and deformation of AHSS. Process modelling including fracture toughness depending properties gives valuable information and additional understanding of fracture behavior and crack propagation mechanisms in AHSS components. Fracture toughness in thin sheets can be readily measured through the application of the Essential Work of Fracture (EWF) methodology. The damage evolution law can be specified in terms of fracture energy (per unit area) or in terms of equivalent plastic failure strain as a function of triaxiality and lode angle. In this work, DENT test samples have been experimentally evaluated and finite element simulations of the DENT tests have been performed. By this approach the numerical study includes mechanical response of AHSS specimen including sharp cracks. In the numerical model, the J-integral was evaluated using the virtual crack-tip extension (VCE) method. From the comparison of the numerical and experimental results of load-displacement for different ligament length cases it is obvious that there are in agreement. Also, the numerically obtained value of fracture toughness Jc, is in agreement with the experimentally measured value of essential work of fracture we.

     

    When finite element based fracture mechanics is applied to practical design, the fracture toughness can be used as design criteria. One appealing property of the evaluation of the J-integral is that it can be evaluated from the far field solution, which facilitates computation as many numerical errors arise close to the crack tip. Evolution of stress- and strain field, plastic zone, J-integral value and other mechanical properties is interesting to study with the combination of experimental and numerical investigations.

    Determination of the essential work of fracture at high strain rates2017In: 6th International Conference Hot Sheet Metal Forming of High-Performance Steel CHS2: June 4-7 2017, Atlanta, Georgia, USA : proceedings / [ed] Mats Oldenburg, Braham Prakash, Kurt Steinhoff, Warrendale, PA: Association for Iron & Steel Technology, AIST , 2017, 261-269 p.Conference paper (Refereed)
    Abstract [en]

    During the last decades, the use of ultra-high strength steel (UHSS) has increased as its favorable ratio between strength and mass allows the design of lighter body-in-white while maintaining passenger safety. Modeling impact loads of components made of UHS steel requires reliable descriptions of the material deformation and fracture behavior.

    Traditional stress or strain based fracture criteria are used in finite element modeling. A different approach in modeling fracture in components uses the fracture energy as a model parameter.

    Fracture toughness is difficult to measure in thin sheets; a method termed Essential Work of Fracture (EWF) provides the possibility to determine the fracture toughness in sheet metal. With knowledge of the fracture toughness the understanding of fracture behavior and crack propagation in ultra-high strength steel can be increased. The obtained EWF is related to the fracture energy and can be used in numerical models as a material parameter.

    In the present work results from preliminary testing are shown and a discussion on cross-head speed and strain rate in the critical specimen cross section is given. The use of digital image correlation provides information about the displacement field in the vicinity of the notch and hence about the strain- and strain rate distribution. Furthermore, the difficulties in reliable measurement of force and elongation in high speed tensile testing machines are elucidated. Issues encountered during the development of the high-speed DENT specimen are not limited to the specific geometry presented in this paper.

    The present work aims at the development of a test specimen to obtain the Essential Work of Fracture (EWF) at high test speed. This work contributes to the overall goal to model fracture behavior and crack propagation, dependent on the strain rate. For the investigation, a high-speed tensile testing machine equipped with an in-house developed load cell and an optical elongation measurement system was used with a high-speed camera to obtain data for digital image correlation.

    A comparative study of different failure modeling strategies on a laboratory scale test component2017In: 6th International Conference Hot Sheet Metal Forming of High-Performance Steel CHS2: June 4-7 2017, Atlanta, Georgia, USA : proceedings / [ed] Mats Oldenburg, Braham Prakash, Kurt Steinhoff, Warrendale, PA: Association for Iron & Steel Technology, AIST , 2017, 37-46 p.Conference paper (Refereed)
    Abstract [en]

    Ultra-high strength steel (UHSS) has become a common material in the automotive industry during the last decades. The technique of press hardening allows modifying and tailoring the material properties of the blank in accordance with desired performance.

    In the present work, a laboratory scale test component is developed. On basis of tests on the component it is intended to investigate the deformation and fracture behavior of a boron alloyed steel after different heat treatments. The tooling is developed to allow the production of single phase microstructures like martensite and bainite as well as mixed microstructures containing ferrite. Testing of the component is performed in a standard tensile testing machine with additional digital speckle measurements to determine the strain to fracture in the critical cross section. The initial geometry shape introduces bending in the critical cross-section during tensile loading of the specimen.

    The aim of this work is to compare different material models on a component like level, including the prediction of failure. A finite element model of a laboratory scale component is analyzed using LS-Dyna. To compare different failure modeling approaches a set of damage models is calibrated to full hardened, martensitic steel. The deformation and fracture behavior of the component is presented in terms of load-displacement, plastic strain-stress triaxiality as well as in principal strain space.

    Instrumentation for silicon tracking at the HL-LHC2017Licentiate thesis, monograph (Other academic)
    Abstract [en]

    In 2027 the Large Hadron Collider (LHC) at CERN will enter a high luminosity phase, deliver- ing 3000 fb 1 over the course of ten years. The High Luminosity LHC (HL-LHC) will increase the instantaneous luminosity delivered by a factor of 5 compared to the current operation pe- riod. This will impose significant technical challenges on all aspects of the ATLAS detector but particularly the Inner Detector, trigger, and data acquisition systems. In addition, many of the components of the Inner Detector are reaching the end of their designed lifetime and will need to be exchanged. As such, the Inner Detector will be entirely replaced by an all silicon tracker, known as the Inner Tracker (ITk).

    The layout of the Pixel and strip detectors will be optimised for the upgrade and will extend their forward coverage. To reduce the per-pixel hit rate and explore novel techniques for deal- ing with the conditions in HL-LHC, an inter-experiment collaboration called RD53 has been formed. RD53 is tasked with producing a front-end readout chip to be used as part of hybrid Pixel detectors that can deal with the high multiplicity environment in the HL-LHC.

    A silicon sensor, which makes up the other half of the hybrid Pixel detector, must also be designed to cope with the high fluences in HL-LHC. Significant damage will be caused by non- ionising energy loss in the sensor over its lifetime. This damage must be incorporated into the detector simulation both to predict the detector performance at specific conditions and to understand the e↵ects of radiation damage on data taking. The implementation of radiation damage in the ATLAS simulation framework is discussed in this thesis.

    Collisions produced by the HL-LHC also presents a challenge for the current track reconstruc- tion software. High luminosity is obtained, in part, by increasing the number of interactions per bunch crossing, which in turn increases the time taken for track reconstruction. Various ap- proaches to circumvent the strain on projected resources are being explored, including porting existing algorithms to parallel architectures. A popular algorithm used in track reconstruction, the Kalman filter, has been implemented in a neuromorphic architecture: IBM’s TrueNorth. The limits of using such an architecture for tracking, as well as how its performance compares to a non-spiking Kalman filter implementation, are explored in this thesis.

    Bathymetry and siltation rate for Dokan Reservoir, Iraq2017In: Lakes & Reservoirs: Research and Management, ISSN 1320-5331, E-ISSN 1440-1770, Vol. 20Article in journal (Refereed)
    Abstract [en]

    The Dokan Reservoir dam is a concrete cylindrical arch with gravity abutments, located on the Lesser Zab River about 60 km from the city of Sulaimani in north-eastern Iraq. A bathymetric survey was conducted in November 2014 for a period of 10 days, using an echo sounder of 200-kHz single beam. The survey results indicated an annual average sediment

    deposition of 3.8 million m 3. Thirty-two sediment samples were collected from the reservoir bed. The ratio of gravel,sand, silt and clay was 15:14:48:23, respectively. The reservoir bed is covered mainly with silt. The sediments are composed of silty clay (77.6%), silty sandy clay (10%), sandy gravely silty clay (1.2%) and gravely sandy silty clay (1%).

    Risk society and culture of safety. Understandings of the task and possibilities of politics

    This paper analyses three different periods with the Swedish Social Democratic Party in office (1960-1965, 1970, 1975 and 1995-2000). The paper analyses how questioning of modernity and the role of science and technology is dealt with in policy documents, such as speeches from the throne, governmental declarations and party programmes. In this discussion the environmental issue is of special interest, since it in a special way challenge the modernistic ideas of progress and possibility to control the future. The analysis shows an increasing emphasis of the modern in the late 1990s. This could be defined as a modernistic answer to the challenges modern society and its institutions have met during the latest decades. Furthermore, environmental protection work - by aid of science and new technology - is defined as a springboard to economic prosperity, which in turn is seen as the basis for the safety of the citizens. In this line the politics of the 1990s is a reminiscens of the 1960s optimistic belief in progress.
