    Island and the Pipeline: Gotland Facing the Geopolitical Power of Nord Stream2017Report (Other academic)
    Abstract [en]

    In 2005, the Nord Stream Consortium launched a pipeline project with the intention to bring Russian natural gas to Germany across the Baltic Sea. Although this raised crucial issues of Russia-EU-Sweden relations on security, energy and the environment the focus of this report is on the Gotland local government response to the Nord Stream approach, thus illustrating the need for a transversal human geography-political studies perspective. Situated in the heart of the Baltic Sea, and in line with the established Swedish governmental "remiss" procedure of commission and referral for consideration the Gotland authority was requested by the Swedish Government to make a statement about the pipeline. How-ever, before the government was even asked for permission the Nord Stream Consortium with Russian Gazprom as the major shareholder turned to the Gotland authority with an offer they after some conflict-ridden twists and turns, manifested in three policy lines as described in the report, decided not to refuse. A narrative inspired analytical ap-proach is applied to dissect the more or less contradictory standpoints and legitimating arguments posed by the actors in the political process preceding the local authority decision to accept the Nord Stream offer, i.e. the local scale actors were provoked to take a stand on a big issue raised by a huge multinational company. By in detail examining the local political repercussions of the energy project the case study contributes to a trans-disciplinary understanding of multi-scalar/multi-level govern-ance. In an epilogue the report also highlights the sudden turnaround of the local narrative in autumn 2016 when Gotland Regional Authority was on the brink of making a deal with Nord Stream II. The turnaround flashlights the geopolitical position of the island in the crossfire of inter-ests concerning the Baltic Sea Region.

    Development and validation of a skin fibroblast biomarker profile for schizophrenic patients2016In: AIMS Bioengineering, ISSN 2375-1495, Vol. 3, no 4, 552-565 p.Article in journal (Refereed)
    Abstract [en]

    Gene expression profiles of non-neural tissues through microarray technology could be used in schizophrenia studies, adding more information to the results from similar studies on postmortem brain tissue. The ultimate goal of such studies is to develop accessible biomarkers. Supervised machine learning methodologies were used, in order to examine if the gene expression from skin fibroblast cells could be exploited for the classification of schizophrenic subjects. A dataset of skin fibroblasts gene expression of schizophrenia patients was obtained from Gene Expression Omnibus database. After applying statistical criteria, we concluded to genes that present a differential expression between the schizophrenic patients and the healthy controls. Based on those genes, functional profiling was performed with the BioInfoMiner web tool. After the statistical analysis, 63 genes were identified as differentially expressed. The functional profiling revealed interesting terms and pathways, such as mitogen activated protein kinase and cyclic adenosine monophosphate signaling pathways, as well as immune-related mechanisms. A subset of 16 differentially expressed genes from fibroblast gene expression profiling that occurred after Support Vector Machines Recursive Feature Elimination could efficiently separate schizophrenic from healthy controls subjects. These findings suggest that through the analysis of fibroblast based gene 553 expression signature and with the application of machine learning methodologies we might conclude to a diagnostic classification model in schizophrenia.

    'In Charge of the Truffula Seeds': On Children's Literature, Rationality and Children's Voices in Philosophy2011In: Journal of Philosophy of Education, ISSN 0309-8249, E-ISSN 1467-9752, Vol. 45, no 2, 359-377 p.Article in journal (Refereed)
    Abstract [en]

    In this paper I investigate how philosophy can speak for children and how children can have a voice in philosophy and speak for philosophy. I argue that we should understand children as responsible rational individuals who are involved in their own philosophical inquiries and who can be involved in our own philosophical investigations-not because of their rational abilities, but because we acknowledge them as conversational partners, acknowledge their reasons as reasons, and speak for them as well as let them speak for us and our rational community. In order to argue this I turn, first, to Gareth Matthews' philosophy of childhood and suggest a reconstruction of some of his concepts in line with the philosophy of Stanley Cavell. Second, in order to examine more closely our conceptions of rationality and our pictures of children, I consider the children's books, The Lorax and Where is My Sister? and Henrik Ibsen's play, The Wild Duck.

    Perfectionist Philosophy as a (an Untaken) Way of Life2014In: The Journal of Aesthetic Education, ISSN 0021-8510, E-ISSN 1543-7809, Vol. 48, no 3, 58-72 p.Article in journal (Refereed)
    Abstract [en]

    I am honored to respond to Paul Guyer’s elaboration on the role of examples of perfectionism in Cavell’s and Kant’s philosophies. Guyer’s appeal to Kant’s notion of freedom opens the way for suggestive readings of Cavell’s work on moral perfectionism but also, as I will show, for controversy.

    There are salient aspects of both Kant’s and Cavell’s philosophy that are crucial to understanding perfectionism and, let me call it, perfectionist education, that I wish to emphasize in response to Guyer. In responding to Guyer’s text, I shall do three things. First, I shall explain why I think it is misleading to speak of Cavell’s view that moral perfectionism is involved in a struggle to make oneself intelligible to oneself and others in terms of necessary and sufficient conditions for moral perfection. Rather, I will suggest that the constant work on oneself that is at the core of Cavell’s moral perfectionism is a constant work for intelligibility. Second, I shall recall a feature of Cavell’s perfectionism that Guyer does not explicitly speak of: the idea that perfectionism is a theme, “outlook or dimension of thought embodied and developed in a set of texts.” Or, as Cavell goes on to say, “there is a place in mind where good books are in conversation. … [W]hat they often talk about … is how they can be, or sound, so much better than the people that compose them.” This involves what I would call a perfectionist conception of the history of philosophy and the kinds of texts we take to belong to such history. Third, I shall sketch out how the struggle for intelligibility and a perfectionist view of engagement with texts and philosophy can lead to a view of philosophy as a form of education in itself.

    In concluding these three “criticisms,” I reach a position that I think is quite close to Guyer’s, but with a slightly shifted emphasis on what it means to read Kant and Cavell from a perfectionist point of view.

    The Philosophy of Dissonant Children: Stanley Cavell's Wittgensteinian Philosophical Therapies as an Educational Conversation2010In: Educational Theory, ISSN 0013-2004, E-ISSN 1741-5446, Vol. 60, no 4, 469-486 p.Article in journal (Refereed)
    Abstract [en]

    Education is often understood as a process whereby children come to conform to the norms teachers believe should govern our practices. This picture problematically presumes that educators know in advance what it means for children to go on the way that is expected of them. In this essay Viktor Johansson suggests a revision of education, through the philosophy of Stanley Cavell, that can account for both the attunement in our practices and the possible dissonance that follows when the teacher and child do not go on together. There is an anxiety generated by the threat of disharmony in our educational undertakings that may drive teachers toward philosophy in educational contexts. Here Johansson offers a philosophical treatment of this intellectual anxiety that teachers may experience when they, upon meeting dissonant children, search for epistemic justifications of their practices—a treatment whereby dissonant children can support teachers in dissolving their intellectual frustrations.

    Understanding users of a future E-care@home system: E-care@home project2017Report (Other academic)
    Abstract [en]

    This technical report contains personas based on the authors’ earlier and ongoing research together with literature studies. The original aim of the work presented in this report was to provide the E-care@home research environment with an understanding of who the user of a hypothetical future E-care@home system is. The resulting personas are to be used as a tool to aid other work packages within the E-care@home research environment in their design processes. The project focuses on technological solutions and uses artificial intelligence for creating a semantic interoperability between sensor data, systems and humans. The release of this report is, however, a result of several requests of data and user specifications coming from both researchers and companies, who want to base their work on realistic situations of elderly people.

    Several interviews have been performed with potential end users: with healthcare providers within geriatrics care at a hospital, within home care services, and with more-or-less-healthy elderly people, focusing on frail elderly people who may be in risk of falling, developing malnutrition and/or pressure ulcers, and also their closest relatives and their caregivers.

    In this report, 15 personas are presented. There are five different elderly personas. Two of them live together with their spouses, one of which is presented as a persona. In addition, the report presents the personas of eight healthcare professionals, all of which are involved in Senior Alert risk assessments and prevention of falls, malnutrition and pressure ulcers. Three personas represent different professions working in the home care services, the other five personas work at a geriatrics hospital ward. Finally, one informal caregiver of an elderly, a daughter, is presented as a persona. These hypothetical and archetypical users shed light on a variety of different users that may interact with an E-care@home system, or other IoT technologies in the future.

    It should be acknowledged that the work presented in this technical report has been extracted from one of E-care@home scientific deliverables, MSR5.1b. The original deliverable, that was authored by Mälardalen University, SICS East and Örebro University, features also personas representing elderly multi-morbid users with specialized home healthcare and a number of use cases that pose challenging scenarios that highlight a range of possible interactions with the E-care@home system.

    Stakeholder engagement in the making: IPBES Legitimization Politics2017In: Global Environmental Politics, ISSN 1526-3800, E-ISSN 1536-0091, Vol. 17, no 1, 59-76 p.Article in journal (Refereed)
    Abstract [en]

    There are a growing number of expert organizations aiming to supply knowledge for global environmental policy-making. Recently, there have also been explicit calls for stakeholder engagement at the global level to make scientific knowledge relevant and usable on the ground. The newly established Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) is one of the first international expert organizations to have systematically developed a strategy for stakeholder engagement in its own right. The paper analyzes the emergence of this strategy. Employing the concept “politics of legitimation”, it examines how and for what reasons stakeholder engagement was introduced, justified and finally endorsed, as well as its effects. The paper explores the process of institutionalizing stakeholder engagement and reconstructs the contestation of the operative norms regulating the conditions of this engagement. The paper concludes by discussing the broader importance of the findings for IPBES, as well as for international expert bodies in general.

    Text- och resursorientering inom multimodalitetsforskningen: En teoretisk diskussion om förklaringsvärden2012In: Språk & Stil, ISSN 1101-1165, Vol. 22:1, no 1, 135-161 p.Article in journal (Refereed)
    Abstract [en]

    This article discusses the explanatory value of two theoretical orientations within multimodal research on texts and communication, and it explores the potential benefits of combining them. Firstly, the multimodal text (involving other semiotic modes than language) can be taken as a point of departure for the analysis and understanding of meaning making. This has been a common approach within text and discourse analysis. Secondly, there is an orientation toward the multimodal resources being employed when people make meaning, placing the interests of sign-/text-makers and processes of text creation just as much in focus as the textual products that emerge from them.

    The discussions in the article primarily make reference to the broader framework of social semiotic multimodality research, taking the theoretical assumptions made in Kress & van Leeuwen’s influential book Reading images: The grammar of visual design (2006) as one important point of departure. In particular, research categorised under the tentative labels of multimodal discourse analysis, social semiotic multimodal analysis and multimodal interactional analysis is reviewed and related to the status the authors ascribe to texts and semiotic resources. The text analytical implications of text and resource orientations and combinations of the two are finally illustrated by a sample analysis of multimodal texts created by children in educational contexts.

    Ecologies of ‘upcycling’ as design for learning in Higher Education2016In: Short papers, 2016, 7-12 p.Conference paper (Other academic)
    Abstract [en]

    As society changes, new ways of understanding and using existing semiotic resources are needed. This study looks at artefacts from a social semiotic perspective in order to explore the concepts of ‘recycling’ and ‘upcycling’ and their relevance for pedagogy in Higher Education. We look at recycling in terms of ‘texts’ and employ methodological tools from multimodal discourse analysis. ‘Recycling’ involves converting materials from one product to create a different product with a different function, without necessarily adding any type of value. In ‘upcycling’, economic, aesthetic or functional value is always added. ‘Upcycling’ can thus be understood as a process of recontextualization of semiotic resources, in both spatio-linguistic and sensory terms. This paper looks at how resources are recontextualized as part of global ecologies of production and consumption. Then, we explore these insights in the pedagogical domain, looking at possible implications of the principles of ‘upcycling’ and value adding through design as a means for educating global critical citizens.

    Only a Shadow: Industrial computed tomography investigation, and method development, concerning complex material systems2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The complexity of components fabricated in today's industry is ever increasing. This increase is partly due to market pressure but it is also a result from progress in fabrication technologies that opens up new possibilities. The increased use of additive manufacturing and multi-material systems, especially, has driven the complexity of parts to new heights. The new complex material systems brings benefits in many areas such as; mechanical properties, weight optimisation, and sustainability. However, the increased complexity also makes material integrity investigations and dimensional control more difficult. In additive manufacturing, for example, internal features can be fabricated which cannot be seen or measured with conventional tools. There is thus a need for non-destructive inspection methods that can measure these geometries. Such a method is X-ray computed tomography. Computed tomography utilizes the X-rays ability to penetrate material to create 3D digital volumes of components. Measurements and material investigations can be performed in these volumes without any damage to the investigated component. However, computed tomography in material science is still not a fully mature method and there are many uncertainties associated with the investigation technique. In the work presented in this thesis geometries fabricated by various additive manufacturing processes have been investigated using computed tomography. Also in this work, a dual-energy computed tomography tool has been developed with the aim to increase the measurement consistency of computed tomography when investigating complex geometries and material combinations.

    Abstract [en]

    Polymers and reinforced plastics are employed in various load-bearing applications, from household objects to aerospace products. These materials are light, strong, and relatively cheap but can be difficult to form into complex geometries. However, the development of additive manufacturing processes has made it easier to manufacture reinforced plastics in complex shapes. The aim of this work was to study the internal features and mechanical properties of carbon fibre-reinforced polyamide (CF/PA12) fabricated with the additive manufacturing technique of selective laser sintering. The test specimens were studied using computed tomography to analyse the internal geometry, and the material proved to be highly porous. Moreover, the test specimens revealed an internal layered structure, which was found to have a great effect on the tensile properties of the material. The results highlight that there is room for further optimisation of the manufacturing parameters for CF/PA12, because the layered structure makes it challenging to design end user parts with acceptable mechanical properties.

    Abstract [en]

    Additive manufacturing (AM) is a set of manufacturing processes currently in rapid development providing designersnew freedoms in their designs. One distinct difference from other manufacturing methods is the ability to makecomplex internal features which can be of great benefit for applications in many industries. These features can bechannels, cavities, filled or not filled with powder, parts in parts etc. In order for these advantages to be industriallyapplicable there is a need for robust verification methods for these internal features. X-ray computed tomography (CT)holds the promise of being one of the few powerful tools for non-destructive imaging of internal features. In this work,selective laser sintering (SLS) has been used to manufacture parts of a complex geometry containing internal cavities.The test specimens were manufactured in two different materials; Polyamide12 and Titanium (Ti6Al4V). In order toinvestigate the limitations and controllability of the process, the dimensions of the internal cavities were determinedby a correlation of tactile measurements on external features and CT-data. The results were also compared to computeraided design (CAD) data. This work provides some insight concerning part accuracy of today’s frontier of AM systemsand the ability to measure and characterize internal features using CT.

    2016 (English)Conference paper (Refereed)
    Abstract [en]

    The complexity of today’s products and materials is ever increasing. There is a demand on the industry to produce lighter, stronger, and more precise products. A common practice to achieve such products is to combine different materials to enhance strengths and reduce weaknesses; multi material products. Fabricating complex parts using multi materials does, however, lead to an increased difficulty in metrological verification and material characterisation. The use of computed tomography is today widespread within the industry, providing new possibilities for internal measurements, but there are still many uncertainties associated with the method. It is well known that large variations in density of multi materials greatly affects the contrast obtained by computed tomography, resulting in difficulties to scan and acquire reliable data from certain material setups.In this work the effects on internal measurements as a consequence of differences in X-ray penetration depth have been studied with regards to multi material setups. The main interest was the ability to acquire measurements from internal features of material compositions that are commonly used in the industry. In the result, difficulties and uncertainties associated with computed tomography of multi materials are highlighted and suggestions on how to reduce problems and obtain a more reliable test method are discussed.

    Abstract [en]

    Computed tomography is increasingly adopted by industries for metrological and material evaluation. The technology enables new measurement possibilities, while also challenging old measurement methods in their established territories. There are, however, uncertainties related with the computed tomography method. Investigation of multi-material components with, in particular, varying material thickness can result in unreliable measurements. In this paper the effects of multi-materials, and differing material thickness, on computed tomography measurement consistency has been studied. The aim of the study was to identify measurement inconsistencies and attempt to correct these with a dual-energy computed tomography approach. In this pursuit, a multi-material phantom was developed, containing reliable measurement points and custom-ability with regards to material combinations. A dual-energy method was developed and implemented using sequential acquisition and pre-reconstruction fusing of projections. It was found that measurements made on the multi-material phantom with a single computed tomography scan were highly inconsistent. It was also found that the dual-energy approach was able to reduce the measurement inconsistencies. However, more work is required with the automation of the dual-energy approach presented in this paper since it is highly operator dependant.

    Spatial Augmented Reality and Eye Tracking for Evaluating Human Robot Interaction2016In: Proceedings of RO-MAN 2016 Workshop: Workshop on Communicating Intentions in Human-Robot Interaction, 2016Conference paper (Refereed)
    Abstract [en]

    Freely moving autonomous mobile robots may leadto anxiety when operating in workspaces shared with humans.Previous works have given evidence that communicating in-tentions using Spatial Augmented Reality (SAR) in the sharedworkspace will make humans more comfortable in the vicinity ofrobots. In this work, we conducted experiments with the robotprojecting various patterns in order to convey its movementintentions during encounters with humans. In these experiments,the trajectories of both humans and robot were recorded witha laser scanner. Human test subjects were also equipped withan eye tracker. We analyzed the eye gaze patterns and thelaser scan tracking data in order to understand how the robot’sintention communication affects the human movement behavior.Furthermore, we used retrospective recall interviews to aid inidentifying the reasons that lead to behavior changes.

    Empirical evaluation of human trust in an expressive mobile robot2016In: Proceedings of RSS Workshop "Social Trust in Autonomous Robots 2016", 2016Conference paper (Refereed)
    Abstract [en]

    A mobile robot communicating its intentions using Spatial Augmented Reality (SAR) on the shared floor space makes humans feel safer and more comfortable around the robot. Our previous work [1] and several other works established this fact. We built upon that work by adding an adaptable information and control to the SAR module. An empirical study about how a mobile robot builds trust in humans by communicating its intentions was conducted. A novel way of evaluating that trust is presented and experimentally shown that adaption in SAR module lead to natural interaction and the new evaluation system helped us discover that the comfort levels between human-robot interactions approached those of human-human interactions.

    Lightning Injury is a disaster in Bangladesh?: Exploring its magnitude and public health needs2016In: F1000 Research, ISSN 0106-3324, E-ISSN 2046-1402, Vol. 5, 2931Article in journal (Refereed)
    Abstract [en]

    Background: Lightning injury is a global public health issue. Low and middle-income countries in the tropical and subtropical regions of the world are most affected by lightning. Bangladesh is one of the countries at particular risk, with a high number of devastating lightning injuries in the past years, causing high mortality and morbidity. The exact magnitude of the problem is still unknown and therefore this study investigates the epidemiology of lightning injuries in Bangladesh, using a national representative sample.

    Methods: A mixed method was used. The study is based on results from a nationwide cross-sectional survey performed in 2003 in twelve randomly selected districts. In the survey, a total of 819,429 respondents from 171,336 households were interviewed using face-to-face interviews. In addition, qualitative information was obtained by reviewing national and international newspaper reports of lightning injuries sustained in Bangladesh between 13 and 15 May 2016.

    Results: The annual mortality rate was 3.661 (95% CI 0.9313–9.964) per 1,000,000 people. The overall incidence of lightning injury was 19.89/100,000 people. Among the victims, 60.12% (n=98) were males and 39.87% (n=65) were females. Males were particularly vulnerable, with a 1.46 times increased risk compared with females (RR 1.46, 95% CI 1.06–1.99). Rural populations were more vulnerable, with a 8.73 times higher risk, than urban populations (RR 8.73, 95% CI 5.13–14.86). About 43% of injuries occurred between 12 noon and 6 pm. The newspapers reported 81 deaths during 2 days of electric storms in 2016. Lightning has been declared a natural disaster in Bangladesh.

    Conclusions: The current study indicates that lightning injuries are a public health problem in Bangladesh. The study recommends further investigations to develop interventions to reduce lightning injuries, mortality and related burden in Bangladesh.

    Snakebite Epidemiology in Bangladesh: A national community based health and injury survey2016In: Health, ISSN 1949-4998, Vol. 8, 479-486 p.Article in journal (Refereed)
    Abstract [en]

    Insert Snakebite is a global public health issue, and in majority of cases it is undermined. Tropical and subtropical countries are most effected, Bangladesh being one of them. There is scarcity of countries’ epidemiological situation in relation to snakebite poisoning. This study has looked at the epidemiological status of snakebite poisoning from national representative survey findings.

    Methods: A nationwide cross-sectional survey was conducted in 12 randomly selected districts of Bangladesh in 2003. A total of 171,366 households were surveyed and information was collected from 819,429 populations by face to face interview. Multi-stage cluster sampling methods were used in this survey and covered urban, rural and slum populations. Results: Annually an estimated 15,372 (10.98/100,000) individuals were bitten by snakes and of them 1709 (1.22/100,000) died every year. Males were found to be most vulnerable with a risk of 1.51 times higher than female. Rural populations were also 10.54 times higher at risk than the populations living in the urban areas. Among the victims 94% were from the poor socio economic conditions. Around 43.9% of the incidences occurred during evening to midnight. Home was found the most common area for snake bite (33.6%), and the Leg was found to be the most common site for biting (63.1%). A total of 96.6% victims sought treatment, of them 61% sought immediate treatment from traditional healing methods.

    Conclusions: Present incidence of snakebite in Bangladesh has clearly shown that there is emerging public health needs for intervention that can reduce the mortality and burden of the disease in the country.

    Tell me about dynamics!: Mapping velocity fields from sparse samples with Semi-Wrapped Gaussian Mixture Models2016In: Robotics: Science and Systems Conference (RSS 2016), 2016Conference paper (Refereed)
    Abstract [en]

    Autonomous mobile robots often require informa-tion about the environment beyond merely the shape of thework-space. In this work we present a probabilistic method formappingdynamics, in the sense of learning and representingstatistics about the flow of discrete objects (e.g., vehicles, people)as well as continuous media (e.g., air flow). We also demonstratethe capabilities of the proposed method with two use cases. Onerelates to motion planning in populated environments, whereinformation about the flow of people can help robots to followsocial norms and to learn implicit traffic rules by observingthe movements of other agents. The second use case relates toMobile Robot Olfaction (MRO), where information about windflow is crucial for most tasks, including e.g. gas detection, gasdistribution mapping and gas source localisation. We representthe underlying velocity field as a set of Semi-Wrapped GaussianMixture Models (SWGMM) representing the learnt local PDF ofvelocities. To estimate the parameters of the PDF we employ aformulation of Expectation Maximisation (EM) algorithm specificfor SWGMM. We also describe a data augmentation methodwhich allows to build a dense dynamic map based on a sparseset of measurements. In case only a small set of observations isavailable we employ a hierarchical sampling method to generatevirtual observations from existing mixtures.

    Uptake and bioaccumulation of PCDD/Fs in earthworms after in situ and in vitro exposure to soil from a contaminated sawmill site2016In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026Article in journal (Refereed)
    Abstract [en]

    Uptake of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) was studied in earthworms collected from a sawmill site in Sweden with severe PCDD/Fs contamination (the hot spot concentration was 690,000 ng TEQWHO2005/kg d.w.) in order to investigate the transfer of PCDD/Fs from the site to the biota. PCDD/Fs concentrations in the collected earthworms were compared to PCDD/Fs concentrations in laboratory exposed earthworms (Eisenia fetida), which were exposed to contaminated soils from the sawmill site for 34 days. All analyses were performed by high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). PCDD/Fs concentrations in the earthworms ranged from 290 to 520,000 pg/g (f.w.). The main congeners found in both soils and earthworms were OCDF, 1234678-HpCDF, OCDD and 1234678-HpCDD. The study showed that the PCDD/Fs in the soil were biovailable to the earthworms and the PCDD/Fs concentrations in the soils correlated with the concentrations in the earthworms. Earthworm samples from soil with lower concentration had higher bioaccumulation factors than samples from soils with high concentration of contamination. Thus, a less contaminated soil could yield higher concentrations in earthworms compared to a higher contaminated soil. Assuming that when assessing risks with PCDD/F contaminated soil, a combination of chemical analysis of soil PCDD/Fs concentrations and bioavailability should be employed for a more comprehensive risk assessment.

    Tracking the shape deformation of voids from tensile loading by the use of computed tomography2015In: Digital Industrial Radiology and Computed Tomography (DIR 2015), 2015, 18034Conference paper (Refereed)
    Abstract [en]

    The understanding of interaction between voids such as pores or holes in additive manufactured open structures is of importance in understanding the strength of components. Behavior in three dimensions is of particular interest. X-ray tomography is one of the few techniques that has the possibility to nondestructively aid in analyzing issues such as shape deformation. In this work, X-ray computed tomography was applied as a nondestructive tool for tracking the shape deformation of voids.

    A simplified model representing three dimensional voids is used to investigate the effect of influential parameters like void size, their distance from each other and orientation of voids in respect to the uniaxial tensile load. A set of ex-situ X-ray micro tomography tensile test is performed on flat aluminum (6082-T6) tensile bars with drilled through holes representing different configuration of voids. Digital image correlation was used to measure the strain localization in the adjacent area of the holes. Corresponding Finite Element (FE) analysis is performed to predict the shape deformation and by this validate the model. This modelling may give a better insight of pores interaction under more complex loading scenarios and leads to better controllability of internal structure design of additive manufactured (AM) parts.

    ExCITE Project: A Review of Forty-Two Months of Robotic Telepresence Technology2016In: Presence - Teleoperators and Virtual Environments, ISSN 1054-7460, E-ISSN 1531-3263, Vol. 25, no 3, 204-221 p.Article in journal (Refereed)
    Abstract [en]

    This article reports on the EU project ExCITE with specific focus on the technical development of the telepresence platform over a period of 42 months. The aim of the project was to assess the robustness and validity of the mobile robotic telepresence (MRP) system Giraff as a means to support elderly people and to foster their social interaction and participation. Embracing the idea of user-centered product refinement, the robot was tested over long periods of time in real homes. As such, the system development was driven by a strong involvement of elderly people and their caregivers but also by technical challenges associated with deploying the robot in real-world contexts. The results of the 42-months’ long evaluation is a system suitable for use in homes rather than a generic system suitable, for example, in office environments.

    Facial EMG reactions to facial expressions: a case of facial emotional contagion?1995In: Scandinavian Journal of Psychology, ISSN 0036-5564, E-ISSN 1467-9450, Vol. 36, no 2, 130-141 p.Article in journal (Refereed)
    Abstract [en]

    The purpose of this study is to explore whether subjects exposed to stimuli of facial expressions respond with facial electromyographic (EMG) reactions consistent with the hypothesis that facial expressions are contagious. This study further examines whether males and females differ in facial EMG intensity. Two experiments demonstrated that subjects responded with facial EMG activity over the corrugator supercilii, the zygomatic major, the lateral frontalis, the depressor supercilii, and the levator labii muscle regions to stimuli of sad, angry, fearful, surprised, disgusted and happy faces, that, to large extent, were consistent with the hypothesis that facial expressions are contagious. Aspects of gender differences reported in earlier studies were found, indicating a tendency for females to respond with more pronounced facial EMG intensity.

    Utsatta elevers maktlöshet: en studie om elevers sociala samvaro som förbättringsarbete i åk 8-92017Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The aim of the thesis is to examine how everyday social interactions and relations in a school class in years 8-9 are experienced by pupils and teachers and how they can be understood and improved. The research design is an action research approach and is carried out as a case study involving four teachers and 24 pupils. Four issues are formulated and the teachers and the researcher together suggest how certain problems might be solved, which in turn directs the action process over the period of three school terms. Analytical concepts are used to map and understand pupils’ everyday social relations in terms of peer groups, positions and norms. Eriksson’s (2001) sociological theory on bullying is used to analyze and explain the complexity of a case of bullying.

    Defined dominating norms that appear to guide the pupils’ social interactions are: (1) You should make room for yourself, be visible and heard, (2) you should have many friends and (3) you should look down on those who study. The everyday social relations are affected by the pupils’ positioning and by the groupings that are formed in the class. Crystalized groups that emerge in the study are: (1) those who make a lot of noise and take up a lot of room, (2) those who study, (3) pupils who are frequently absent, (4) those who feel uncomfortable and (5) those who are outside (a marginalized group). In addition to these findings, three dominating norms among the teachers emerge. These norms guide and affect how the teachers act and think when victimized pupils and their situations are discussed. Teachers’ dominating norms seem to prevail in situations where some pupils are victimized by other pupils in the class. This in turn could contribute to various kinds of moral disengagement on the part of the teachers when dealing with victimizing acts among pupils. From the perspective of the victimized pupils, such a way of acting could be understood as teachers, in their role as “security guarantors”, are unable to prevent the powerlessness of victimized pupils.

    Representations of women researchers in Finnish print media: top researchers, multi-talents and experts [Representaciones de mujeres investigadoras En la prensa escrita finlandesa: investigadoras de élite, multi-talentos y expertas]2016In: Investigaciones Feministas, ISSN 2171-6080, Vol. 7, no 2, 203-224 p.Article in journal (Refereed)
    Abstract [en]

    Women’s underrepresentation in the scientific community is currently on the agenda of science policy, both in Europe and internationally. The significance of media as a provider of female role models, on the one hand, and in reproducing stereotypical images of scientists, on the other hand, is often mentioned in this context. However, there is relative lack of research on how women researchers are depicted in the media, especially outside US and UK contexts. Finland provides an interesting context to study media representations of women in research, as a relatively gender equal and research intensive setting seen from a global perspective.The media representations of women researchers in Finland were explored by analyzing person interviews in Finnish printed media: newspapers, women’s magazines and magazines aimed for general public. The data consists of 107 interviews of women researchers from all fields of research, published in 1997-2014. Overwhelming majority of the interviews was written by female journalists. The analysis focuses on both social and linguistic aspects of the interviews from a gender perspective. Women researchers were found to be represented by a variation of frames, the most common of which were the Expert and the Top Researcher. Their family context was frequently mentioned, and the interviews frequently commented their appearance(e.g. hair, physique, way of moving).The fact that the interviewees’ family context was often highlighted in the interviews may serve to convey a message that it is possible and common to combine a career in research and family.One main result of the study was the diversity of representations of female researchers,compared to US and UK studies. The diversity of the media images of female researchers suggests that the media may provide important role models for young women, encouraging women to choose research as a profession.

    Maternal complications in a geographically challenging and hard to reach district of Bangladesh: a qualitative study2016In: F1000 Research, ISSN 0106-3324, E-ISSN 2046-1402, Vol. 5, 2417Article in journal (Refereed)
    Abstract [en]

    Background: Maternal complications contribute to maternal deaths in developing countries. Bangladesh still has a high prevalence of maternal mortality, which is often preventable. There are some geographically challenging and hard to reach rural districts in Bangladesh and it is difficult to get information about maternal complications in these areas. In this study, we examined the community lay knowledge of possible pregnancy complications. We also examined the common practices associated with complications and we discuss the challenges for the community.

    Methods: The study was conducted in Moulvibazar of north east Bangladesh, a geographically challenged, difficult to reach district. Qualitative methods were used to collect the information. Pregnant women, mothers who had recently delivered, their guardians and traditional birth attendants participated in focus group discussions. Additionally, in-depth interviews were conducted with the family members. Thematic analyses were performed.

    Results: The study revealed that there is a lack of knowledge of maternal complications. In the majority of cases, the mothers did not receive proper treatment for maternal complications. There are significant challenges that these rural societies need to address: problems of ignorance, traditional myths and family restrictions on seeking better treatment. Moreover, traditional birth attendants and village doctors also have an important role in assuring appropriate, effective and timely treatment.

    Conclusions: The rural community lacks adequate knowledge on maternal complications. Reduction of the societal barriers including barriers within the family can improve overall practices. Moreover, dissemination of adequate information to the traditional birth attendant and village doctors may improve the overall situation, which would eventually help to reduce maternal deaths.

    The Economic Cost of Implementing Maternal and Neonatal Death Review in a District of Bangladesh2016In: Journal of Public Health Research, ISSN 2279-9028, E-ISSN 2279-9036, Vol. 5, no 3, 729Article, review/survey (Refereed)
    Abstract [en]

    Introduction: Maternal and neonatal death review (MNDR) introduced in Bangladesh and initially piloted in a district during 2010. MNDR is able to capture each of the maternal, neonatal deaths and stillbirths from the community and government facilities (hospitals). This study aimed to estimate the cost required to implement MNDR in a district of Bangladesh during 2010-2012.

    Materials and Methods: MNDR was implemented in Thakurgaon district in 2010 and later gradually extended until 2015. MNDR implementation framework, guidelines, tools and manual were developed at the national level with national level stakeholders including government health and family planning staff at different cadre for piloting at Thakurgaon. Programme implementation costs were calculated by year of costing and costing as per component of MNDR in 2013. The purchasing power parity conversion rate was 1 $INT = 24.46 BDT, as of 31st Dec 2012.

    Results: Overall programme implementation costs required to run MNDR were 109,02,754 BDT (445,738 $INT $INT) in the first year (2010). In the following years cost reduced to 8,208,995 BDT (335,609 $INT, during 2011) and 6,622,166 BDT (270,735 $INT, during 2012). The average cost per activity required was 3070 BDT in 2010, 1887 BDT and 2207 BDT required in 2011 and 2012 respectively. Each death notification cost 4.09 $INT, verbal autopsy cost 8.18 $INT, and social autopsy cost 16.35 $INT. Facility death notification cost 2.04 $INT and facility death review meetings cost 20.44 $INT. One death saved by MNDR costs 53,654 BDT (2193 $INT).

    Conclusions: Programmatic implementation cost of conducting MPDR give an idea on how much cost will be required to run a death review system for a low income country settings using government health system.

    Bumping against the boundary: IPBES and the knowledge divide2017In: Environmental Science and Policy, ISSN 1462-9011, E-ISSN 1873-6416, Vol. 69, 22-28 p.Article in journal (Refereed)
    Abstract [en]

    Founded in 2012, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is one of the most ambitious attempts to date to bridge the divide between scientific knowledge and indigenous and local knowledge. Doing so requires overcoming participatory, epistemological and ontological challenges, including different communicative forms, diverging criteria for knowledge validation, and conflicting views of nature. Central IPBES documents are analyzed to see how the platform deals with these challenges. While IPBES constitutes an unprecedented, innovative and ambitious institutional design for the cross-fertilization of knowledge, the results show that IPBES (i) struggles to reconcile an open, collaborative atmosphere with the demands for structure set by the scientific format, (ii) tends to shy away from potentially conflict-laden issues and disagreements, (iii) often treats scientific knowledge and indigenous or local knowledge as easily distinguishable entities, and (iv) has yet to solve the epistemological challenges of knowledge generation and validation when working across knowledge-systems. Taken together, these features seem to hinder the cross-fertilization of knowledge. The case of IPBES thus holds important lessons for future efforts to transform both knowledge production and the overall framing of challenges within global environmental governance.

    Freedom with what?: Interpretations of “responsibility” in Swedish forestry practice2017In: Forest Policy and Economics, ISSN 1389-9341, E-ISSN 1872-7050, Vol. 75, 34-40 p.Article in journal (Refereed)
    Abstract [en]

    Responsibility is a key aspect of all regulation, and forest regulation is no exception. Howshould responsibility be understood and used in a time characterized by complexity and uncertainty? This paper develops a typology that distinguishes six notions of responsibility and then employs it in analyzing interpretations of responsibility in Swedish forestry practice. The Swedish forest management system is a deregulated system structured by the governing principle of “freedom with responsibility.” By investigating how responsibility is understood and enacted by forest consultants and forest owners, we demonstrate the practical fluidity of the responsibility concept. We emphasize the need for an understanding of responsibility that fosters sensitivity and adaptiveness to external issues and actors in the face of uncertainty, and identify obstacles in current forestry policy and practice to enacting such an understanding.

    Seniors´self-preservation by maintaining established self and defying deterioration: A grounded theroy2016In: International Journal of Qualitative Studies on Health and Well-being, ISSN 1748-2623, E-ISSN 1748-2631, Vol. 11, 30265Article in journal (Refereed)
    Abstract [en]

    The purpose of this classic grounded theory study was to understand how seniors who are living independently resolve issues influenced by visual impairment and high fall risk. We interviewed and observed 13 seniors with visual impairment in their homes. We also interviewed six visual instructors with experience from many hundreds of relevant incidents from the same group of seniors. We found that the seniors are resolving their main concern of ‘‘remaining themselves as who they used to be’’ by self-preservation. Within this category, the strategies maintaining the established self and defying deterioration emerged as the most prominent in our data. The theme maintaining the established self is mostly guided by change inertia and includes living the past (retaining past activities, reminiscing, and keeping the home intact) and facading (hiding impairment, leading to avoidance of becoming a burden and to risk juggling). Defying deterioration is a proactive scheme and involves moving (by exercising, adapting activities, using walking aids, driving), adapting (by finding new ways), and networking by sustaining old support networks or finding new networks. Self-preservation is generic human behavior and modifying this theory to other fields may therefore be worthwhile. In addition, health care providers may have use for the theory in fall preventive planning.

    Translation, adaptation, and validation of the behavioral pain scale and the critical-care pain observational tools in Taiwan2016In: Journal of Pain Research, ISSN 1178-7090, E-ISSN 1178-7090, Vol. 9, 661-669 p.Article in journal (Refereed)
    Abstract [en]

    This study describes the cultural adaptation and testing of the behavioral pain scale (BPS) and the critical-care pain observation tools (CPOT) for pain assessment in Taiwan. The cross-cultural adaptation followed the steps of translation, including forward translation, back-translation, evaluation of the translations by a committee of experts, adjustments, and then piloting of the prefinal versions of the BPS and the CPOT. A content validity index was used to assess content validities of the BPS and the CPOT, with 0.80 preset as the level that would be regarded as acceptable. The principal investigator then made adjustments when the content validity index was,0.80. The pilot test was performed with a sample of ten purposively selected patients by 2 medical staff from a medical care center in Taiwan. The BPS and the CPOT are adequate instruments for the assessment of pain levels in patients who cannot communicate due to sedation and ventilation treatments.

    Men do care!: A gender-aware and masculinity-informed contribution to caregiving scholarship2016Doctoral thesis, monograph (Other academic)
    Abstract [en]

    In caregiving literature, it is often the female gender that has been the focus of attention, and in particular women’s unpaid labor. Studies also tend to make comparisons between men’s and women’s caregiving, using men’s caregiving experiences to show not only that women face greater burdens, but also that men’s needs can be minimized. This means that while gender analysis is not uncommon in the caregiving literature, gender tends to be equated with womanhood. This is impeding us from moving the debates on care and caregiving forward. The dissertation argues – through a phenomenological analysis of men’s motives, experiences and perceptions of care and caregiving – that much could be gained if we were to rectify the gender bias by bringing attention to caregiving men in the gender-aware and masculinity-informed way that is lacking in the family caregiving literature at present. For this dissertation, 19 caregiving adult sons and sons-in-law were interviewed. The aim of the study is twofold. Firstly, it attempts to contribute to the rectification of the gender bias found in the literature on family caregiving by focusing on men’s caregiving and answering the following research questions: What motivates men to provide care for their elderly parents? How do adult sons experience caregiving? What do adult sons think that care and caregiving are, i.e. what are their perspectives on care? Secondly, this dissertation also aims to explore whether a gender-aware and masculinity-informed perspective can be used to enhance our understanding of caregiving. This study discusses how motives, experiences and perspectives, which have so far been interpreted as unique to women, are also matters that men talk about and consider important in caregiving. Thus, this study shows that a gender-aware and masculinity-informed perspective on care can increase our understanding of family caregiving and contribute to rectify the gender bias that care research suffers from. The study suggests that caregiving men should not solely be regarded as empirically interesting. This is because they are an unexploited and theoretically profuse source of information about caregiving.

    A reflexive look at reflexivity in environmental sociology2017In: Environmental Sociology, ISSN 2325-1042, Vol. 3, no 1, 6-16 p., Article in journal (Refereed)
    Abstract [en]

    Reflexivity is a central concept in environmental sociology, as in environmental social science in general. The concept is often connected to topics such as modernity, governance, expertise, and consumption. Reflexivity is presented as a means for taking constructive steps towards sustainability as it recognizes complexity, uncertainty, dilemmas, and ambivalence. Critical discussion of the conceptual meaning and usage of reflexivity is therefore needed. Is it a useful theoretical concept for understanding various sustainability issues? Is ‘more reflexivity’ relevant and useful advice that environmental sociologists can give in communicating with other disciplines, policymakers, and practitioners? This article explores the conceptual meaning of reflexivity and assesses its relevance for environmental sociology. In particular, it reviews its usages in three research fields; expertise, governance, and citizen-consumers. The paper furthermore discusses the spatial and temporal boundaries of reflexivity. It concludes by discussing how the concept can be a useful analytical concept in environmental sociology, at the same time as it warns against an exaggerated and unreflexive use of the concept.
