    Human-mediated introduction of geoengineering earthworms in the Fennoscandian arctic2018Ingår i: Biological Invasions, ISSN 1387-3547, E-ISSN 1573-1464, Vol. 20, nr 6, s. 1377-1386Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It is now well established that European earthworms are re-shaping formerly glaciated forests in North America with dramatic ecological consequences. However, few have considered the potential invasiveness of this species assemblage in the European arctic. Here we argue that some earthworm species (Lumbricus rubellus, Lumbricus terrestris and Aporrectodea sp.) with great geomorphological impact (geoengineering species) are non-native and invasive in the Fennoscandian arctic birch forests, where they have been introduced by agrarian settlers and most recently through recreational fishing and gardening. Our exploratory surveys indicate no obvious historical dispersal mechanism that can explain early arrival of these earthworms into the Fennoscandian arctic: that is, these species do not appear to establish naturally along coastlines mimicking conditions following deglaciation in Fennoscandia, nor were they spread by early native (Sami) cultures. The importance of anthropogenic sources and the invasive characteristics of L. rubellus and Aporrectodea sp. in the arctic is evident from their radiation outwards from abandoned farms and modern cabin lawns into adjacent arctic birch forests. They appear to outcompete previously established litter-dwelling earthworm species (i.e. Dendrobaena octaedra) that likely colonized the Fennoscandian landscape rapidly following deglaciation via hydrochory and/or dispersal by early Sami settlements. The high geoengineering earthworm biomasses, their recognized ecological impact in other formerly glaciated environments, and their persistence once established leads us to suggest that geoengineering earthworms may pose a potent threat to some of the most remote and protected arctic environments in northern Europe.

    Hur förmedlas kristendomen i läromedelstexter för gymnasieskolan? En ideologikritisk analys2018Ingår i: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, nr 2018:2, s. 23-44Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study aims at investigating how the image of the religion of Christianity is constructed in Swedish textbooks for the Upper Secondary School (gymnasieskolan), with a specific focus on the perspective from which the text considers the religion and how this perspective creates possibilities for and limitations of pupils’ identification. Introductions of Christianity through text and images were selected from six current textbooks; five printed and one digital. The method used for analysis was ideological text criticism with a combination of Linguistic and Theological perspectives. Three aspects were highlighted in the analysis: interest making strategies, demands of previous knowledge, and subject perspectives. The study showed that the examined texts did not express Christianity as the cultural norm as considered in previous research. Instead there seemed to be an ambivalence in the perspective from which the textbooks considered the religion. Demands of previous knowledge as well as subject positions varied highly both within and between textbooks.

    Religionsvetenskapliga tröskelbegrepp: stötestenar och språngbrädor vid utvecklingen av ett ämnesperspektiv2018Ingår i: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, nr 2018:2, s. 1-22Artikel i tidskrift (Refereegranskat)
    Abstract [sv]

    Att behärska en vetenskaplig disciplin är utmanande, och olika vetenskapliga discipliner har sina säregna utmaningar för noviser, eller nybörjare som närmare sig ämnet. Tröskelbegrepp (eng: threshold concepts) har visat sig vara pedagogiskt fruktbara begrepp, relaterat till just det gradvisa erövrandet av ett ämnesperspektiv. Teorin introduceras, följt av en kort översikt av användning inom området religionsundervisning (religious education). Tidigare forskning har framför allt behandlat konfessionell religionsundervisning. Med hjälp av empiriskt material (intervju och enkät) från studenter inom religionsvetenskap förankras den allmänna diskussionen till ett svenskt högskolesammanhang i en argumentation för att levd religion, världsreligionparadigmet, emic/etic, samt ortodoxi/ortopraxi kan vara tröskelbegrepp inom religionsvetenskap i Sverige. Dessa kan ses som nycklar in i det vetenskapliga ämnet religionsvetenskap, och genom att nyttja tröskelbegreppen vid planering av kurser kan undervisningen förbättras.

    När dispositiva lagregler blir tvingande: om behov av kreativitet i det aktiebolagsrättsliga lagstiftningsarbetet2017Ingår i: Svensk Juristtidning, ISSN 0039-6591, nr 1, s. 9-22Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [sv]

    Genom dispositiv lagstiftning erbjuds en flexibilitet för parter som finner att lagens utgångspunkt inte passar deras kontrakt. Forskning visar dock att dispositiviteten många gånger inte utnyttjas. I denna artikel diskuteras ekonomiska och psykologiska skäl till varför aktieägare avstår från att avtala bort bolagsrättsliga regler, trots att andra lösningar hade passat deras företag bättre. Det sagda får till följd att dispositiva aktiebolagsrättsliga lagregler likväl blir tvingande och sättet för lagstiftaren att bemöta detta är genom att överväga en annan regleringsteknik.

    Mosquitoborne Sindbis Virus Infection and Long-Term Illness2018Ingår i: Emerging Infectious Diseases, ISSN 1080-6040, E-ISSN 1080-6059, Vol. 24, nr 6, s. 1141-1142Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An unexpected human outbreak of the mosquitoborne Sindbis virus occurred in a previously nonendemic area of Sweden. At follow-up, 6-8 months after infection, 39% of patients had chronic arthralgia that affected their daily activities. Vectorborne infections may disseminate rapidly into new areas and cause acute and chronic disease.

    Getting the mix right?: The use of labour contract alternatives in UK construction2007Ingår i: Personnel review, ISSN 0048-3486, E-ISSN 1758-6933, Vol. 36, nr 4, s. 549-563Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose - The purpose of this paper is to examine the use of contingent labour in the construction and civil engineering sector in the UK. Design/methodology/approach - The paper presents the findings of a national postal survey of employment practices within the UK construction and civil engineering sector. The survey was conducted in 2002 and covered firms of all sizes within the sector. This technique has been supplemented with in-depth interviews to provide a deeper understanding of the issues raised. Findings - The paper finds that employers’ use of contingent labour is widespread and that in many cases, the use of contingent labour has increased over recent years. It is argued that recourse to the use of contingent labour may increasingly be a constrained choice for employers, reflecting overall labour shortages and recruitment difficulties in the sector. The paper also finds that the use of contingent labour contributes to skills shortages in the industry, with the scope of training offered to workers on these contract forms being limited in nature. Originality/value - The paper reveals the complex relationship between the use of contingent labour and ongoing skills shortages in the sector. The paper concludes that the cycle of turning to contingent labour in response to recruitment difficulties does not replenish the skill profile of the sector and therefore offers no long-term solution to the skills shortages within the construction industry. © Emerald Group Publishing Limited.

    Data quality of whole genome bisulfite sequencing on Illumina platforms2018Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, nr 4, artikel-id e0195972Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The powerful HiSeq X sequencers with their patterned flowcell technology and fast turnaround times are instrumental for many large-scale genomic and epigenomic studies. However, assessment of DNA methylation by sodium bisulfite treatment results in sequencing libraries of low diversity, which may impact data quality and yield. In this report we assess the quality of WGBS data generated on the HiSeq X system in comparison with data generated on the HiSeq 2500 system and the newly released NovaSeq system. We report a systematic issue with low basecall quality scores assigned to guanines in the second read of WGBS when using certain Real Time Analysis (RTA) software versions on the HiSeq X sequencer, reminiscent of an issue that was previously reported with certain HiSeq 2500 software versions. However, with the HD.3.4.0 /RTA 2.7.7 software upgrade for the HiSeq X system, we observed an overall improved quality and yield of the WGBS data generated, which in turn empowers cost-effective and high quality DNA methylation studies.

    The elusive ligand complexes of the DWARF14 strigolactone receptor2018Ingår i: Journal of Experimental Botany, ISSN 0022-0957, E-ISSN 1460-2431, Vol. 69, nr 9, s. 2345-2354Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Strigolactones, a group of terpenoid lactones, control many aspects of plant growth and development, but the active forms of these plant hormones and their mode of action at the molecular level are still unknown. The strigolactone protein receptor is unusual because it has been shown to cleave the hormone and supposedly forms a covalent bond with the cleaved hormone fragment. This interaction is suggested to induce a conformational change in the receptor that primes it for subsequent interaction with partners in the signalling pathway. Substantial efforts have been invested into describing the interaction of synthetic strigolactone analogues with the receptor, resulting in a number of crystal structures. This investigation combines a re-evaluation of models in the Protein Data Bank with a search for new conditions that may permit the capture of a receptor-ligand complex. While weak difference density is frequently observed in the binding cavity, possibly due to a low-occupancy compound, the models often contain features not supported by the X-ray data. Thus, at this stage, we do not believe that any detailed deductions about the nature, conformation, or binding mode of the ligand can be made with any confidence.

    From networks to hierarchies: The construction of a subcontracting regime in the irish telecommunications industry2008Ingår i: Organization Studies, ISSN 0170-8406, E-ISSN 1741-3044, Vol. 29, nr 6, s. 867-886Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The perceived displacement of bureaucracy by external market relationships through the use of subcontracting has brought about an increase in interest in inter-organizational relations. The development of such relationships can be a protracted process, characterized by tensions and contradictions. The article traces the development of subcontracting within Eircom, the Irish telecommunications provider, from its relatively ad hoc origins in the mid-1990s to the development of a far more sophisticated contracting regime by 2003. The article explores the relationship between internal and external organizational changes associated with the construction of the subcontracting regime and the development of inter-organizational relationships. The subcontracting regime was transformed from a reliance on a series of decentralized local networks of suppliers to a highly centralized arrangement that bore increasing semblance to a unitary hierarchy. The transactions costs implications of such developments are considered throughout. The dynamics of change in this case reflect an incremental learning process as the organization adapted to changes in its environment and the emergent limitations of existing practices. Trust played an important role in the mediation of the subcontract relationships; however, the development of trust-based relationships was not a linear process. © 2008 SAGE Publications.

    Living in precarity: Ethnography of everyday struggles of single mothers in Lithuania2018Ingår i: Sociologija, ISSN 0038-0318, Vol. 60, nr 1, s. 64-83Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper presents challenges and life strategies of highly educated single mothers in Lithuania. My ethnography traces the impact on strategies of remaining in a country where exit strategies – alcoholism, suicide, emigration – prevail and seem as an “easier” option. It is a study concerned with the relationship between precarity, single motherhood, social reproduction and everyday living. I focus on precarious living conditions, social isolation and stigmatization, unappreciated and highly gendered care-work. Based on collaborative ethnographic fieldwork material, the paper presents the micro-level attempts to negotiate what it means to be a lone care-taker, to revalorize and challenge the hegemonic narratives of individual strength and success.

    Techniques for and consequences of using INSPIRE extensions: a case study with Swedish hydrological data2018Ingår i: International Journal of Spatial Data Infrastructures Research, ISSN 1725-0463, E-ISSN 1725-0463, Vol. 13, s. 172-201Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The demand for easily available geographic information is increasing in society. Moreover, knowledge of spatial data infrastructures (SDIs) has increased in many European governmental agencies, in large part because of the implementation of the INSPIRE directive. Many countries, thus, recognise the need to provide more detailed geographic information as network services at the national level. One means of realising this goal is to create INSPIRE extensions, i.e., to extend the INSPIRE data specifications with more detailed and specific national information. This paper describes a study where a complex INSPIRE extension has been created to describe the national need of hydrography information in Sweden, based on the Swedish water system standard (SWSS). The study includes the creation of a UML application schema that extends the INSPIRE Hydrography (HY) theme, the transform from UML to an XSD schema, the creation of GML files, and finally, testing and evaluating the approach of using INSPIRE extensions. When evaluating the results, the consequences of replacing existing dataset/download services with one extended INSPIRE HY dataset/download service are evaluated from the perspectives of both users and data providers. The evaluation is carried out as quantitative tests of the resulting GML files, in a user-centric test where a user tests the applicability of the GML files in hydrological analyses, and by telephone interviews with personnel from Lantmäteriet, the Swedish mapping, cadastral and land registration authority. Beside these evaluations, the possible effects on the information modelling process when creating an INSPIRE extension are also examined. The study shows that it is possible to create complex INSPIRE extensions that include many object types, attributes and relations. From a user perspective, extended INSPIRE HY files do not differ substantially from SWSS files, and can be used in hydrological analyses. Data providers can relatively simply replace their current download services with one for the extended INSPIRE HY, but the specific economic consequences for this could not be drawn. It could be expected, though, that there can be both economic, administrative and maintenance advantages if today’s separate INSPIRE and national download services are replaced with services exposing datasets based on an extended INSPIRE data model for all adequate themes.

    Mathematical Modeling of Rogue Waves: A Survey of Recent and Emerging Mathematical Methods and Solutions2018Ingår i: Axioms, E-ISSN 2075-1680, Vol. 7, nr 2Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Anomalous waves and rogue events are closely associated with irregularities and unexpected events occurring at various levels of physics, such as in optics, in oceans and in the atmosphere. Mathematical modeling of rogue waves is a highly active field of research, which has evolved over the last few decades into a specialized part of mathematical physics. The applications of the mathematical models for rogue events is directly relevant to technology development for the prediction of rogue ocean waves and for signal processing in quantum units. In this survey, a comprehensive perspective of the most recent developments of methods for representing rogue waves is given, along with discussion of the devised forms and solutions. The standard nonlinear Schrödinger equation, the Hirota equation, the MMT equation and other models are discussed and their properties highlighted. This survey shows that the most recent advancement in modeling rogue waves give models that can be used to establish methods for the prediction of rogue waves in open seas, which is important for the safety and activity of marine vessels and installations. The study further puts emphasis on the difference between the methods and how the resulting models form the basis for representing rogue waves in various forms, solitary or with a wave background. This review has also a pedagogic component directed towards students and interested non-experts and forms a complete survey of the most conventional and emerging methods published until recently.

    Critical behavior within 20 fs drives the out-of-equilibrium laser-induced magnetic phase transition in nickel2018Ingår i: Science Advances, ISSN 0036-8156, E-ISSN 2375-2548, Vol. 4, nr 3, artikel-id eaap9744Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It has long been known that ferromagnets undergo a phase transition from ferromagnetic to paramagnetic at the Curie temperature, associated with critical phenomena such as a divergence in the heat capacity. A ferromagnet can also be transiently demagnetized by heating it with an ultrafast laser pulse. However, to date, the connection between out-of-equilibrium and equilibrium phase transitions, or how fast the out-of-equilibrium phase transitions can proceed, was not known. By combining time-and angle-resolved photoemission with time-resolved transverse magneto-optical Kerr spectroscopies, we show that the same critical behavior also governs the ultrafast magnetic phase transition in nickel. This is evidenced by several observations. First, we observe a divergence of the transient heat capacity of the electron spin system preceding material demagnetization. Second, when the electron temperature is transiently driven above the Curie temperature, we observe an extremely rapid change in the material response: The spin system absorbs sufficient energy within the first 20 fs to subsequently proceed through the phase transition, whereas demagnetization and the collapse of the exchange splitting occur on much longer, fluence-independent time scales of similar to 176 fs. Third, we find that the transient electron temperature alone dictates the magnetic response. Our results are important because they connect the out-of-equilibrium material behavior to the strongly coupled equilibrium behavior and uncover a new time scale in the process of ultrafast demagnetization.

    A model to study complement involvement in experimental retinal degeneration2018Ingår i: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 123, nr 1, s. 28-42Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The complement system (CS) plays a role in the pathogenesis of a number of ocular diseases, including diabetic retinopathy (DR), glaucoma, uveitis, and age-related macular degeneration (AMD). Given that many of the complex eye-related degenerative diseases have limited treatment opportunities, we aimed to mimic the in vivo retinal degenerative process by developing a relevant co-culture system.

    Method and materials: The adult porcine retina was co-cultured with the spontaneously arising human retinal pigment epithelial cells-19 (ARPE-19).

    Results: Inflammatory activity was found after culture and included migrating microglial cells, gliosis, cell death, and CS activation (demonstrated by a minor increase in the secreted anaphylotoxin C3a in co-culture). CS components, including C1q, C3, C4, soluble C5b-9, and the C5a receptor, were expressed in the retina and/or ARPE cells after culture. C1q, C3, and CS regulators such as C4 binding protein (C4BP), factor H (CFH), and factor I (CFI) were secreted after culture.

    Discussion: Thus, our research indicates that this co-culturing system may be useful for investigations of the CS and its involvement in experimental neurodegenerative diseases.

    Effekterna av begränsat antal handledarskap: en utvärdering2018Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Tidigare kunde en handledare ha ett obegränsat antal godkännanden men i och med de nya föreskrifterna begränsades dessa till 15 stycken. Det övergripande syftet med denna studie är att undersöka huruvida denna begränsning har haft en effekt på den olagliga körskoleverksamheten. Ett annat viktigt syfte är att ge förslag på alternativa åtgärder för att stävja denna verksamhet. För att svara på dessa frågor har vi använt oss av tre olika angreppssätt; en registerstudie, en intervjustudie och en enkätstudie. Resultaten från intervjustudien visar att det finns en rad olika tjänster som den olagliga verksamheten erbjuder mot betalning; förfalskning av handledarintyg, handledd körträning, kunskapsprov som man filmat på plats och som andra kan få tillgång till, hjälp att svara på kunskapsfrågorna i samband med prov via en öronsnäcka och bokning av förarprov. Det vanligaste enligt de intervjuade är att man erbjuder handledning vid körträning. Hur omfattande den olagliga verksamheten är gav intervjustudien inte något entydigt svar på. Svaren varierade allt från att den är väldigt stor till liten.

    Resultat från enkätstudien ger dock indikationer på att det finns en olaglig verksamhet som är relativt utbredd. På frågan om regelverket haft en positiv eller negativ inverkan på den olagliga verksamheten var de intervjuade tämligen överens om att den inte haft någon effekt alls. Argumentet var att de som idag sysslar med denna verksamhet, i varje fall den grövre, är så pass raffinerade att de säkert kommer på olika sätta att kringgå även dessa regler. Trots det fanns det några som skulle vilja se en ytterligare sänkning, även om detta inte skulle räcka för att stävja den olagliga verksamheten. Man pratade då istället om att en sänkning tydligt visar att det handlar om en privat verksamhet och inte en yrkesverksamhet. Det övergripande resultatet från studierna är att en illegal verksamhet kan rubba förtroendet för det svenska körkortet. Rapporten avslutas med 16 olika åtgärdsförslag som tillsammans kan hjälpa till att stävja den olaglig verksamhet. Detta innebär att en åtgärd inte löser problemet.

    Relapsing Fevers: Neglected Tick-Borne Diseases2018Ingår i: Frontiers in Cellular and Infection Microbiology, E-ISSN 2235-2988, Vol. 8, artikel-id 98Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Relapsing fever still remains a neglected disease and little is known on its reservoir, tick vector and physiopathology in the vertebrate host. The disease occurs in temperate as well as tropical countries. Relapsing fever borreliae are spirochaetes, members of the Borreliaceae family which also contain Lyme disease spirochaetes. They are mainly transmitted by Ornithodoros soft ticks, but some species are vectored by ixodid ticks. Traditionally a Borrelia species is associated with a specific vector in a particular geographical area. However, new species are regularly described, and taxonomical uncertainties deserve further investigations to better understand Borrelia vector/host adaptation. The medical importance of Borrelia miyamotoi, transmitted by Ixodes spp., has recently spawned new interest in this bacterial group. In this review, recent data on tick-host-pathogen interactions for tick-borne relapsing fevers is presented, with special focus on B. miyamotoi.

    Optically controlled dielectric properties of single-walled carbon nanotubes for terahertz wave applications2018Ingår i: Nanoscale, ISSN 2040-3364, E-ISSN 2040-3372Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Materials with tunable dielectric properties are valuable for a wide range of electronic devices, but are often lossy at Terahertz frequencies. Here we experimentally report the tuning of the dielectric properties of single-walled carbon nanotubes under light illumination. The effect is demonstrated by measurements of impedance variations at low frequency as well as complex dielectric constant variations in the wide frequency range of 0.1-1 THz by time domain spectroscopy. We show that the dielectric constant is significantly modified for varying light intensities. The effect is also practically applied to phase shifters based on dielectric rod waveguides loaded with carbon nanotube layers. The carbon nanotubes are used as tunable impedance surface controlled by light illumination, in the frequency range of 75-500 GHz. These results suggest that the effect of dielectric constant tuning with light, accompanied by low transmission losses of the carbon nanotube layer in such ultra-wide band, may open up new directions for the design and fabrication of novel Terahertz and optoelectronic devices.

    Dynamic Texture Recognition Using Time-Causal and Time-Recursive Spatio-Temporal Receptive Fields2018Ingår i: Journal of Mathematical Imaging and Vision, ISSN 0924-9907, E-ISSN 1573-7683, s. 1-30Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This work presents a first evaluation of using spatio-temporal receptive fields from a recently proposed time-causal spatiotemporal scale-space framework as primitives for video analysis. We propose a new family of video descriptors based on regional statistics of spatio-temporal receptive field responses and evaluate this approach on the problem of dynamic texture recognition. Our approach generalises a previously used method, based on joint histograms of receptive field responses, from the spatial to the spatio-temporal domain and from object recognition to dynamic texture recognition. The time-recursive formulation enables computationally efficient time-causal recognition. The experimental evaluation demonstrates competitive performance compared to state of the art. In particular, it is shown that binary versions of our dynamic texture descriptors achieve improved performance compared to a large range of similar methods using different primitives either handcrafted or learned from data. Further, our qualitative and quantitative investigation into parameter choices and the use of different sets of receptive fields highlights the robustness and flexibility of our approach. Together, these results support the descriptive power of this family of time-causal spatio-temporal receptive fields, validate our approach for dynamic texture recognition and point towards the possibility of designing a range of video analysis methods based on these new time-causal spatio-temporal primitives.

    How gender theories are used in contemporary public health research2018Ingår i: International Journal for Equity in Health, ISSN 1475-9276, E-ISSN 1475-9276, Vol. 17, artikel-id 34Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Public health research often focuses on gender differences within certain diagnoses, but so far research has failed to explain these differences in a satisfactory way. Theoretical development could be one prerequisite for moving beyond categorical thinking. The aim of this paper was to analyse how gender theories have been used in public health research in relation to various methodological approaches. Method: Six special issues of gender research with public health relevance (comprising 33 papers in total) were identified from a search of PubMed and Web of Science, spanning a 10-year period. The papers were analysed inductively through posing questions to the text. Results: Gender theories were used in eight different ways: 1. to test hypotheses, 2. integrate theories, 3. develop gender concepts and models, 4. interpret findings, 5. understand health problems, 6. illustrate the validity of other theories, 7. integrated into a gender blind theory, as well as to 8. critique of other gender theories. The strategies applied seemed independent of the health aspects of the papers. However, the methodologies were of importance, indicating that both theoretical papers and papers using qualitative methodologies used almost all available strategies, while papers using quantitative empirical research used a limited number of strategies. Conclusions: This study contributes to identifying how gender theories are used in contemporary public health research, which can help researchers move beyond a categorical understanding of gender in health research.

    The Invisible Hand?: Critical Information Infrastructures, Commercialisation and National Security2018Ingår i: The International Spectator: Italian Journal of International Affairs, ISSN 0393-2729, E-ISSN 1751-9721, Vol. 53, nr 2, s. 124-140Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Corporatisation of critical information infrastructure (CII) is rooted in the ‘privatisation wave’ of the 1980s-90s, when the ground was laid for outsourcing public utilities. Despite well-known risks relating to reliability, resilience, and accountability, commitment to efficiency imperatives have driven governments to outsource key public services and infrastructures. A recent illustrative case with enormous implications is the 2017 Swedish ICT scandal, where outsourcing of CII caused major security breaches. With the transfer of the Swedish Transport Agency’s ICT system to IBM and subcontractors, classified data and protected identities were made accessible to non-vetted foreign private employees – sensitive data could thus now be in anyone’s hands. This case clearly demonstrates accountability gaps that can arise in public-private governance of CII.

    Seismic microzonation for earthquake risk mitigation in turkey2004Konferensbidrag (Refereegranskat)
    Abstract [en]

    As a tool to improve the state of land use management in Turkey and to better mitigate earthquake risk inthe future, a microzonation project was initiated after the 1999 Kocaeli earthquake. The project had twocomponents (a) drafting a microzonation manual [1], (b) conducting pilot case studies in the selected tworegions affected by the 1999 Marmara earthquakes [2]. The main purpose of the study was to test anddemonstrate the applicability of the methodology proposed in the Seismic Microzonation Manual preparedfor the project. The major contributions of the study are the probabilistic assessment of the regionalearthquake hazard, interpretation of the microtremor records, and interpretation of the available geologicaland geotechnical data based on a grid approach. All the available data was transformed to GIS format andthe results are evaluated to obtain a microzonation with respect to site amplification, liquefactionsusceptibility and landslide hazard. An attempt will be made to summarize the results of the pilot studyconducted for the Gölcük region to give an overview of the proposed methodology.

    Resource acquisition and the complexity of social capital: Perspectives from women entrepreneurs in Tanzania and Pakistan2018Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Över hela världen bidrar kvinnors företagande till att skapa innovationer, arbetstillfällen och ekonomiskt värde i sina respektive ekonomier. Trots att företagande kvinnor fyller en viktig funktion som pådrivare av utveckling, finns relativt lite forskning kring förutsättningar för kvinnors företagande. Detta gäller i synnerhet för utvecklingsländer, vilket är problematiskt, då kvinnor har potential att spela en avgörande roll för utveckling i alla samhällen, inte minst genom företagande. Entreprenörskap har sedan länge betraktats som en avgörande faktor för ekonomisk utveckling och en mängd studier har bekräftat entreprenörskapets ekonomiska värde. Brist på kapital och andra resurser är samtidigt en begränsande faktor för start och expansion av nya företag, speciellt i utvecklingsekonomier, där de finansiella marknaderna ofta är underutvecklade eller dysfunktionella. Tidigare forskning visar vidare att kvinnor som driver företag möter särskilt stora barriärer i sitt sökande efter kapital och andra resurser, samt att de tvingas hantera både formella och informella hinder.

    Syftet med denna avhandling är att bidra till tidigare kunskap om kvinnors företagande i utvecklingsländer, genom att utforska och beskriva företagande kvinnors resursanskaffning. Syftet är vidare att utforska vilken betydelse formella och informella institutioner har, samt vilken betydelse socialt kapital har, i relation till resursanskaffning. Avhandlingen baseras på två fältstudier,vilka genomförts i två olika utvecklingskontexter – Tanzania och Pakistan. Studierna pågick under längre tidsperioder och data samlades in genom semistrukturerade intervjuer, en enkät och deltagande observation. Fokus är på företagande kvinnor och deras anskaffande av kapital och andra resurser. Vidare fokuseras vilken roll formella och informella institutioner spelar i relation till företagande kvinnors resursanskaffande, samt vilken roll socialt kapital spelar för resursanskaffandet. Särskilt uppmärksammas de kontextuella förutsättningarna.

    Resultaten från de fyra artiklar som ingår i avhandlingen visar att de studerade grupperna av entreprenörer har liknande finansiella beteende. I båda kontexterna saknar kvinnor nästan helt tillgång till formellt kapital från banker och tvingas i stället förlita sig på informella källor till kapital och resurser, framför allt från familjemedlemmar. I Tanzania spelar mikrobankerna en viktig roll, tillsammans med andra semi-formella aktörer (exempelvis SACCOs och RoSCAs). I Pakistan är mikrofinanssektorn mindre utvecklad. Även där finns semi-formella aktörer att vända sig till (exempelvisså kallade ”committees”), men det är betydligt vanligare att använda egna besparingar och lån eller bidrag från familjemedlemmar. Vidare visar resultaten att företagande kvinnor tvingas navigera genom ett komplext nät av barriärer, både formella och informella. Respondenter i båda studerade kontexter ser informella kontakter (såsom familjemedlemmar, vänner och sociala nätverk) som viktiga källor till kapital och andra resurser. Trots detta uttrycker de tydligt att de efterfrågar kapital från pålitliga, väl fungerande, formella finansiella institutioner. Slutligen bekräftar resultaten tidigare studier, där socialt kapital påvisas vara av avgörande betydelse för entreprenörer. Eftersom kvinnor i de studerade kontexterna är exkluderade från formell finansiering, är de i än högre grad beroende av informellt kapital och därmed förmågan att använda socialt kapital. Det är dock anmärkningsvärt hur ofta de sociala strukturer som kvinnorna är inbäddade i, inte bara ärkomplexa, utan även direkt kontraproduktiva. Resultaten visar på både negativa effekter av, och begränsad tillgång till, socialt kapital för de studerade entreprenörerna.

    Potential Ecodesign Requirements for Textiles and Furniture2018Bok (Övrigt vetenskapligt)
    Abstract [en]

    A large part of the lifecycle environmental impacts of a product are determined at the design stage, why The EU Eco design Directive’s potential for application to non-energy related themes has come under the spotlight in recent years with Nordic countries at the forefront. In this report potential eco design requirements that can be drawn up for non-energy-related products are in focus. Textiles are here used as an example, and a light application of the approach has subsequently been applied to the furniture sector. Clothing and home textiles were chosen due to significant wastage in the value chain due to fast fashion, dropping quality and relatively low repair and reuse rates.The project was initiated and financed by the Nordic Council of Ministers and led by its Working Group for Sustainable Consumption and Production. A separate Policy Brief (ANP2018:739) is also published.

    (Investigating) MNCs' CSR-related behaviour and impacts in institutionally and culturally distant markets: African developing-countries in focus2018Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The overall purpose of this thesis is to explore why and how institutional distance and contextual differences influence MNCs’ CSR-related behavior in African developing-countries. In order to achieve the purpose stated above, the thesis seeks to answer the overarching research question: How do institutional distance and contextual differences influence MNCs’ CSR-related behavior in African developing countries? To answer the research question this thesis employed an interpretive methodological approach in order to increase my understanding of the CSR phenomenon in a specific contextual environment characterized by different institutional distance through different theoretical and empirical perspectives (Guba and Lincoln, 1994; Lincoln and Guba, 2000). The thesis consists of two qualitative case studies, a systematic literature review, a conceptual paper focused on analyzing distance and MNC foreign subsidiaries’ CSR-related behaviour, and a longitudinal content analysis of annual CSR reports.

    The thesis found that the most prevalent CSR themes addressed in journal articles focused on developing-countries have been social issues, followed by environmental issues as a distant second, with ethics-related issues receiving the least attention. The findings further indicate that CSR rhetoric plays a more positive and significant role than so far explored in CSR research, as it incentivises the host-communities to push for the fulfilment of their CSR expectations or CSR initiatives proposed by the mining companies. Soft’ regulations to which members of industry associations voluntarily adhere mitigate the absence of enforcement of more stringent hard regulations by the state for companies. In doing business in distant or different institutional contexts, institutional duality of MNC subsidiaries renders business activities complex and even conflicting when it comes to seeking internal and external legitimacy. This finding and the proposed model extend Hillman and Wan’s (2005) argument of the existence of ‘institutional duality’ of MNC subsidiaries. The 60-item disclosure index is in itself a contribution to research as it provides a measure of ‘disclosure quality’ in relation to the disclosures of CSR-related performance information and CSR-related governance information.

    The main theoretical contribution of the thesis is that CSR expectations in developing-countries are distinct and may be more important to know how these empirical realities are taken into account when firms with their origin in developed-countries internationalize and enter markets in developing-countries. Second, an extended model is proposed which illustrates the roles of organizational fields, institutional pressures, legitimating environments, and legitimating strategies for MNC subsidiaries’ voluntary disclosure of CSR performance information. The overall contribution of the thesis is that it deepens our understanding of the CSR phenomenon, and of the role of host-communities and MNC subsidiaries’ managers from the context of developing-countries.

    Since its introduction by Gibson (1979)the concept of affordance has been debated by a number of researchers. Most famous, perhaps is the disagreement between Gibson and Norman(1988)about whether affordances are inherent properties of objects or are only present when perceived by an organism. More recently, affordance has been drawn on in the educational arena, particularly with respect to multimodality (see Fredlund, 2015 for a recent example). 

    In the presentation the interrelated concepts of disciplinary affordance and pedagogical affordance will be presented. Both concepts make a radical break with the views of both Gibson and Norman in that rather than focusing on the perception of an individual, they refer to the disciplinary community as a whole. Disciplinary affordance is "the agreed meaning making functions that a semiotic resource fulfills for a disciplinary community". Similarly, pedagogical affordance is "the aptness of a semiotic resource for the teaching and learning of some particular educational content" (Airey, 2015). As such, in a teaching situation the question of whether these affordances are inherent or perceived becomes moot. Rather, the issue is the process through which students come to use semiotic resources in a way that is accepted within the discipline. In this characterization then, learning can be framed in terms of coming to perceive and leverage the disciplinary affordances of semiotic resources.

    An Ultra Low-Loss Silicon-Micromachined Waveguide Filter for D-Band Telecommunication Applications2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    A very low-loss micromachined waveguide bandpassfilter for use in D-band (110–170GHz) telecommunication applicationsis presented. The 134–146GHz filter is implemented in a silicon micromachined technology which utilises a double H-plane split, resulting in significantly lower insertion loss than conventional micromachined waveguide devices. Custom split-blocks are designed and implemented to interface with the micromachined component. Compact micromachined E-plane bends connect the split-blocks and DUT. The measured insertion loss per unit length of the waveguide technology (0.008–0.016 dB/mm) is the lowest reported to date for any micromachined waveguide at D-band. The fabricated 6-pole filter, with a bandwidth of 11.8 GHz (8.4%), has a minimum insertion loss of 0.41 dB, averaging 0.5 dB across its 1 dB bandwidth, making it the lowest-loss D-band filter reported to date in any technology. Its return loss is better than 20 dB across 85% of the same bandwidth. The unloaded quality factor of a single cavity resonator implemented in this technology is estimated to be 1600.

    Micromachined Waveguides with Integrated Silicon Absorbers and Attenuators at 220–325 GHz2018Ingår i: IEEE MTT-S International Microwave Symposium, IEEE conference proceedings, 2018 / [ed] IEEE, IEEE, 2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper reports for the first time on micromachined waveguides with integrated micromachined silicon absorbers. In contrast to epoxy-based microwave absorbers, micromachined lossy silicon absorbers are fully compatible with high temperature fabrication and assembly processes for micromachined waveguides. Furthermore, micromachining enables the fabrication of exact, near ideal taper tips for the silicon absorbers, whereas the tip of epoxy-based absorbers cannot be shaped accurately and reproducibly for small waveguides. Silicon of different conductivity is a very well understood and characterized dielectric material, in contrast to conventional absorber materials which are not specified above 60 GHz. Micromachined silicon waveguides with integrated absorbers and attenuators were designed, fabricated and characterized in the frequency band of 220 – 325 GHz. The return and insertion loss for various taper-geometry variations of double-tip tapered absorbers and attenuators was studied. The average return loss for the best investigated device is 19 dB over the whole band. The insertion loss of the two-port attenuators is 16 – 33 dB for different designs and shows an excellent agreement to the simulated results. The best measured devices of the one-port absorbers exhibit an average and worst-case return loss of 22 dB and 14 dB, respectively, over the whole band. The return loss is not characterized by a good simulation-measurement match, which is most likely attributed to placement tolerances of the absorbers in the waveguide cavities affecting the return but not the insertion loss.

    An optimisation approach for pre-runtime scheduling of tasks and communication in an integrated modular avionic system2018Ingår i: Optimization and Engineering, ISSN 1389-4420, E-ISSN 1573-2924Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In modern integrated modular avionic systems, applications share hardware resources on a common avionic platform. Such an architecture necessitates strict requirements on the spatial and temporal partitioning of the system to prevent fault propagation between different aircraft functions. One way to establish a temporal partitioning is through pre-runtime scheduling of the system, which involves creating a schedule for both tasks and a communication network. While avionic systems are growing more and more complex, so is the challenge of scheduling them. The scheduling of the system has an important role in the development of new avionic systems, since functionality is typically added to the system over a period of several years and a scheduling tool is used both to detect if the platform can host the new functionality and, if this is possible, to create a new schedule. For this reason an exact solution strategy for avionics scheduling is preferred over a heuristic one. In this paper we present a mathematical model for an industrially relevant avionic system and present a constraint generation procedure for the scheduling of such systems. We apply our optimisation approach to instances provided by our industrial partner. These instances are of relevance for the development of future avionic systems and contain up to 20,000 tasks to be scheduled. The computational results show that our optimisation approach can be used to create schedules for such instances within a reasonable time.

    Why People Hate Health Economics – Two Psychological Explanations2018Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Most people dislike the idea of “health economists” having influence on medical decision making and who gets what when it comes to health care. Health economics is often thought of as inhumane, promoting efficiency at the expense of more profound moral values, such as equality and need. The fact that allocations solely based on cost-effectiveness are unlikely to be compatible with public views has been illustrated in experimental studies (1, 2). Moreover, lessons from the Oregon experience on priority setting illuminated that rationing decisions based on health maximization are likely to conflict with the view of the general public. For an economist this can be hard to understand, why is not the quest to maximize the value for money something that strikes a chord with the general public? Here we will outline two fundamental psychological mechanisms that will help to explain why people hate health economics.

    The two psychological mechanisms – taboo-tradeoffs and compassion fade – are emotional phenomena that bias decision-making. These biases are of amplified by the fact that health is of special moral importance to most people. Not only our own health, but other people’s health as well. Moreover, decisions on how to allocate scarce resources in health care also ultimately lead to policies that carry life and death consequences. Thus, health care rationing elicits strong emotions making it an area of decision-making where emotion and reason often diverge. We will argue that health economics at large has been oblivious to the core aspects of human nature outlined in this paper, and this has limited the use of health economics as a productive input in health policy.

    Uncommon vocabulary in mathematical tasks in relation to demand of reading ability and solution frequency2015Ingår i: Nordic Studies in Mathematics Education, Vol. 20, nr 1, s. 101-128Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study reports on the relation between commonness of the vocabulary used in mathematics tasks and aspects of students’ reading and solving of the tasks. The vocabulary in PISA tasks is analyzed according to how common the words are in a mathematical and an everyday context. The study examines correlations between different aspects of task difficulty and the presence of different types of uncommon vocabulary. The results show that the amount of words that are uncommon in both contexts are most important in relation to the reading and solving of the tasks. These words are not connected to the solution frequency of the task but to the demand of reading ability when solving the task

    Water chemistry and runoff in forest streams at Kloten1982Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    Natural variability of stream water composition and discharge was studied in the Kloten area, Central Sweden, by means of statistical methods and simulation technique. The effects of Urea (155 kgN ha-1) and ammonium nitrate (AN, 160 kgN ha-1) fertilization and clear-cutting were studied by comparing treated and reference streams before and after management.

    The concentrations of the chemical constituents and runoff were mostly inhomogeneous in space and time and the coefficients of variation were considerable.

    Urea fertilization had a more prolonged nitrogen leaching and a total of 750 kgN km-2 compared with AN treated areas (500 kgN km-2). The difference was due to higher nitrate leaching. Base cation leaching was larger and pH increased after Urea fertilization. pH decreased after AN fertilization.

    Runoff increased 180 mm year-1 after clear-cutting, while no significant change was found after fertilization. The immediate effect of clear-cutting on stream water chemistry was an increase in dissolved organic matter, followed by increased leaching of ammonia (10x), nitrate (9x) and potassium (4.8x). The total excess leaching of nitrogen was 1 040 kgN km-2 during the first three years after clear-cutting.

    A Norwegian hydrochemical model, that explained stream water composition, was modified and parameterized (40 parameters) for two catchments to analyse differences between them.

    The differences in parameters between the catchments were interpreted as differences in slopes close to the drainage net, dilution due to different evaporation, differences in standing biomass and current annual increment and slightly different mineral composition of the soils. pH at high flows could be deduced from stand characteristics.

    Evaluation of a high framerate multi-exposure laser speckle contrast imaging setup2018Ingår i: High-Speed Biomedical Imaging and Spectroscopy III: Toward Big Data Instrumentation and Management / [ed] Kevin K. Tsia, Keisuke Goda, SPIE - International Society for Optical Engineering, 2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    We present a first evaluation of a new multi-exposure laser speckle contrast imaging (MELSCI) system for assessing spatial variations in the microcirculatory perfusion. The MELSCI system is based on a 1000 frames per second 1-megapixel camera connected to a field programmable gate arrays (FPGA) capable of producing MELSCI data in realtime. The imaging system is evaluated against a single point laser Doppler flowmetry (LDF) system during occlusionrelease provocations of the arm in five subjects. Perfusion is calculated from MELSCI data using current state-of-the-art inverse models. The analysis displayed a good agreement between measured and modeled data, with an average error below 6%. This strongly indicates that the applied model is capable of accurately describing the MELSCI data and that the acquired data is of high quality. Comparing readings from the occlusion-release provocation showed that the MELSCI perfusion was significantly correlated (R=0.83) to the single point LDF perfusion, clearly outperforming perfusion estimations based on a single exposure time. We conclude that the MELSCI system provides blood flow images of enhanced quality, taking us one step closer to a system that accurately can monitor dynamic changes in skin perfusion over a large area in real-time

    Health, Longevity and Pension Reform2018Rapport (Övrigt vetenskapligt)
    Abstract [en]

    In this paper, we study alternative pension reforms designed to achieve fiscal sustainability

    in the face of demographic change. We are particularly interested in the

    heterogeneous effects across demographic groups, as improvements in health and

    longevity have not been uniform across the population. To this end, we develop a dynamic,

    structural life cycle model of heterogeneous agents who face health, mortality

    and income risk. We consider the following policy reform measures: (1) increasing

    the early access age to pensions, (2) raising income taxes, (3) lowering pension benefits

    and (4) lowering pension and disability benefits. We find that, of the considered

    policies, proportionally lowering pension and disability benefits results in the highest

    average welfare and the lowest degree of inequality. It is also successful at boosting

    employment, particularly among the less educated.

    Deep Dynamics2018Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Combining micro and macro data, we construct demand-side shocks, which we take to be exogenous for individual firms. We estimate a reduced-form model to describe how firms adjust their production, employment, capital stock, and inventories in response to such shocks. Then, we chose the structural parameters of a theoretical model so that the theoretical model can match the impulse-response functions from the estimated reduced-form model. Firms’ reactions to demand-side shocks are well explained by a model where firms have modest market power, face convex adjustment costs and where they can vary utilization flexibly. The stock-out motive helps to explain inventory dynamics.

    The adaptation of the Dignity Care Intervention to a Swedish context2018Ingår i: Nordic Conference in Nursing Research - Methods and Networks for the future, 2018, 2018Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Background: The Dignity Care Intervention (DCI) was developed in Scotland by Johnston and co-workers for nurses in municipality care, to enhance dignity in persons with palliative care needs. DCI includes a questionnaire, examples of reflective questions and suggests care actions. DCI has been tested in Ireland, and is now adapted to Swedish.

    Objective: To translate and adapt the DCI to a Swedish palliative context.

    Method: The questionnaire was translated and adapted into Swedish and reviewed by an expert group, before validated in cognitive interviews (N=7) with older persons. To update evidence concerning care actions from a Swedish context, a review of Swedish research literature and interviews with older persons, relatives and health care professionals were carried out. This gathered knowledge has been integrated into the Swedish DCI (DCI-SWE) and a feasibility study now takes place in one municipality in home care, Sweden. Included nurses got repeated information and participated in a shorter DCI-education, and will use the DCI in their everyday work for three months. Follow-up interviews will be conducted and analysed with qualitative content analysis.

    Results: The Swedish version of the questionnaire was experienced relevant for older persons, and both the Swedish review and the interviews gave culturally relevant proposals about dignity care actions. Further, a feasibility study will contribute to the ongoing development of the Swedish DCI-version.

    Conclusion and implication for practice: Implementing DCI in Sweden can enhance dignity in persons with palliative care needs and facilitate for a person-centered care.

    Enhancing dignity in older persons in Sweden: adaptation of the Dignity Care Intervention2018Ingår i: 24th Nordic Congress of Gerontology, 2018Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Background : In end of life, the older persons´ experiences of dignity can be affected due to serious illness and life changes, derived from physical, psychological, social and existential dimension. Loss of dignity impact the persons´ will to live. The Dignity Care Intervention (DCI) was developed and tested in Scotland and Ireland, to enhance dignity of older persons with palliative care needs, by nurses in municipality care. DCI consists a patient dignity inventory, reflective questions and examples of evidence-based care actions.

    The aim was to develop and adapt the DCI to a Swedish context.

    Methods: The patient dignity inventory was overall accepted by older persons in home care, however some changes in the wording were performed. The Swedish care actions reflected mostly earlier care actions described in the original version. However some more care actions derived in some of the categories in the Swedish DCI (DCI-SWE) e.g. “social support”, and some less care actions derived for example in the category “aftermath concerns”.  In DCI-SWE general care actions like e.g. to show respect were concretized unlike the original DCI.

    Conclusions: The DCI-SWE has prospects to enhance older persons´ dignity, and is now tested in a feasibility study by twelve nurses in home care.

    Crew acceleration exposure, health and performance in high-speed operations at sea2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    The presented research program investigates the association between working conditions aboard High-Speed Craft (HSC) and its outcomes in terms of acceleration exposure and crew health and systems performance respectively. The aim is to identify the related risk factors and further, to use them to improve the assessment criteria in a simulation-based-design framework. The investigation initially document a seaborne population by a web-based questionnaire tailored for High-Performance Marine Craft Personnel (HPMCP) and similar populations. Then data is collected during regular service by measuring craft acceleration and through another questionnaire especially resolute on perceived work-exposure, health and performance. Exposure and performance data is collected daily and health data weekly, depending on seaborne frequency. The population repeats the prevalence questionnaire about a year later enabling a longitudinal follow-up for identifying long-term effects of exposure. The paper reports the two questionnaires´ development and pilot test as well as the first application for baseline data collection in the target group. The results indicate health and performance characteristics of the study population and data shows a promising correlation between the self-reported subjective exposure and the measured objective acceleration. Data indicates a comparatively higher prevalence of musculoskeletal pain in the study population than that of the general population.

    En intervention för att bevara sköra äldre personers värdighet: utveckling och anpassning till en svensk kontext 2018Ingår i: Forskningen och utvecklingens dag, 2018, Örebro, 2018Konferensbidrag (Övrigt vetenskapligt)
    Abstract [sv]

    Bakgrund: Utvärdering av palliativ vård i Sverige har visat att vården är ojämlik och att äldre personer får sämre palliativ vård. För att främja äldre personers livskvalitet den sista tiden i livet är bevarande av värdighet grundläggande. Förlust av värdighet kan innebära förtvivlan, en känsla av att vara en börda för andra och en önskan om att få dö, vanliga upplevelser hos sköra äldre personer. Konkreta arbetssätt behöver därför utvecklas för att bevara äldre personers värdighet, vilket idag saknas inom svensk palliativ vård. En värdighetsbevarande intervention (DCI) har utvecklats och prövats i Skottland och Irland. Interventionen består av ett formulär för kartläggning av värdighet, reflekterande frågor samt evidensbaserade vårdhandlingar.

    Syfte: Syftet var att utveckla och anpassa DCI till en svensk kontext.

    Metod: Utveckling och kulturanpassning skedde genom 1) översättning och anpassning av formuläret till svensk kontext via en expertpanel och via kognitiva intervjuer med äldre personer 2) identifiering av värdighetsbevarande vårdhandlingar relevanta för en svensk kontext, utifrån en litteraturgenomgång samt via intervjuer med äldre personer, deras närstående och vårdpersonal.

    Resultat: Mindre revideringar av formuläret genomfördes, men överlag accepterades det av de äldre personerna. Identifierade värdighetsbevarande vårdhandlingar speglade mestadels de redan angivna i originalversionen DCI. Dock framkom fler vårdhandlingar än i originalet vid några av kategorierna i den svenska DCI (DCI-SWE) som t.ex. ”socialt stöd”, medan det framkom färre vårdhandlingar än originalet vid t.ex. ”dödens följder för andra”. I DCI-SWE konkretiserades generella vårdhandlingar som t.ex. att lyssna och visa respekt, till skillnad från originalet.

    Konklusion: DCI-SWE har möjlighet att främja sköra äldre personers värdighet, och prövas nu av sjuksköterskor i en genomförbarhetsstudie inom hemsjukvården.

    Investigation of research needs regarding the storage of hydrogen gas in lined rock caverns: Prestudy for Work Package 2.3 in HYBRIT Research Program 12018Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Syftet med HYBRIT RP1 är att undersöka och utvärdera möjliga vägar till att göra värdekedjorna för energi-gruva-järn-stål fossilfria och därigenom ge en grund för industriella utvecklingsarbeten och den framtida omställningen. En viktig del i HYBRIT-konceptet utgörs av behovet av lagring av stora volymer vätgas. Lagring i inklädda bergrum är ett möjligt alternativ: en storskalig demonstrationsanläggning för lagring av naturgas byggdes 2002 i södra Sverige och har använts sedan dess. Eftersom denna anläggning konstruerades för naturgas, är syftet med denna rapport att undersöka det nuvarande forskningsbehovet för att kunna lagra vätgas i en sådan typ av anläggning. Detta kommer att utgöra basen för det fortsatta arbetet inom delprojekt 2.3 i HYBRIT RP1.

    Efter att ha studerat resultaten från svensk och internationell forskning, samt erfarenheterna från byggnation av inklädda bergrum för gaslagring, är slutsatsen att inklädda bergrum utgör ett rimligt alternativ för lagring av vätgas. Avseende bergmekanik finns det för närvarande inga kritiska frågeställningar. Däremot finns möjlighet att vidareutveckla riskbaserade dimensioneringsmetoder för inklädda bergrum, vilket kan stärka förmågan till god riskhantering vid byggnation av sådana anläggningar. Rapporten identifierar flera forskningsuppslag inom detta område att arbeta med inom delprojekt 2.3: utveckling av en riskbaserad dimensioneringsmetod med hjälp av subset-simulering, studie av optimeringspotentialen för betongliningens tjocklek, samt hur bergmassans rumsliga variation påverkar en plats lämplighet för anläggandet av ett inklätt bergrum.

    Avseende materialfrågor finns dock en kritisk frågeställning för underjordisk vätgaslagring: vätgasförsprödning av stålliningen ses som ett möjligt problem och bör studeras vidare. Men eftersom detta inte är relaterat till bergmekanik kommer det inte att studeras vidare inom delprojekt 2.3.

    Biomimicry in the Nordic Countries2018Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The awareness of Biomimicry within the processes of design and development in Nordic companies are not well known. As a result, The Nordic Council of Ministers Working Group for Sustainable Consumption and Production has called for this report to highlight Nordic forerunners in Biomimicry and actors and activities in the field of biomimicry, biomimetics and biologically inspired design in Nordic countries today. The study conducted by Torben Lenau, Lilli Linkola and Anna Maria Orrù, will present a basis for planning further activities to leverage the possibilities for actors in biomimicry and to disseminate knowledge and methodology on if and how nature's solutions can provide environmental and competitive advantages in business development. Results showed that over 100 organisations and almost 100 professionals from the Nordic countries are listed in the stakeholder map.

    The secondary spiral lamina and its relevance in cochlear implant surgery2018Ingår i: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 123, nr 1, s. 9-18Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: We used synchrotron radiation phase contrast imaging (SR-PCI) to study the 3D microanatomy of the basilar membrane (BM) and its attachment to the spiral ligament (SL) (with a conceivable secondary spiral lamina [SSL] or secondary spiral plate) at the round window membrane (RWM) in the human cochlea. The conception of this complex anatomy may be essential for accomplishing structural preservation at cochlear implant surgery.

    Material and methods: Sixteen freshly fixed human temporal bones were used to reproduce the BM, SL, primary and secondary osseous spiral laminae (OSL), and RWM using volume-rendering software. Confocal microscopy immunohistochemistry (IHC) was performed to analyze the molecular constituents.

    Results: SR-PCI reproduced the soft tissues including the RWM, Reissner's membrane (RM), and the BM attachment to the lateral wall (LW) in three dimensions. A variable SR-PCI contrast enhancement was recognized in the caudal part of the SL facing the scala tympani (ST). It seemed to represent a SSL allied to the basilar crest (BC). The SSL extended along the postero-superior margin of the round window (RW) and immunohistochemically expressed type II collagen.

    Conclusions: Unlike in several mammalian species, the human SSL is restricted to the most basal portion of the cochlea around the RW. It anchors the BM and may influence its hydro-mechanical properties. It could also help to shield the BM from the RW. The microanatomy should be considered at cochlear implant surgery.

    More secure attachment to the father and the mother is associated with fewer depressive symptoms in adolescents2018Ingår i: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 123, nr 1, s. 62-67Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: To investigate whether more secure attachment to the father and the mother is associated with less depressive symptoms among adolescents, and to explore possible sex differences.

    Method: A population-based sample of adolescents completed a school-based survey assessing demographic data, attachment to father and mother, as well as depressive symptoms. Participation rate was 80% of the eligible population, and 3,988 adolescents (1,937 boys and 2,051 girls) had complete data for the analyses.

    Results: Paired samples t tests showed that participants rated their attachment to mothers as slightly more secure than their attachment to fathers (t = 15.94, P < 0.001; boys: t = 5.23, P < 0.001; girls: t = 16.16, P < 0.001). In linear regression analyses there was an association between the outcome, number of depressive symptoms, and more secure attachment to the mother for boys (B=-0.532; 95% confidence interval [CI] -0.656, -0.407, P < 0.001) and for girls (B = -0.623; 95% CI -0.730, -0.516, P < 0.001). Analogous results were found for more secure attachment to the father for boys (B = -0.499; 95% CI -0.608, -0.391, P < 0.001) and for girls (B = -0.494; 95% CI -0.586, -0.401, P < 0.001).

    Conclusions: Understanding the relationship between attachment to both father and mother and depressive symptoms in adolescent boys and girls is essential for further development of strategies for prevention and treatment of depression.

    Task-based language teaching with smartphones: A case study in Pakistan2017Ingår i: Teachers and Curriculum, ISSN 2382-0349, Vol. 17, nr 2, s. 33-40Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Integration of technology in task-based language teaching (TBLT) has long been a source of attraction for language teachers (Pierson, 2015). In the case of developing countries, such as Pakistan, mobile phones are the modern form of technology commonly available at low cost to individuals as well as institutions. The present descriptive case study explores the impact of ubiquitous smartphones and a TBLT approach on students’ and teachers’ perception and motivation in improving English writing skills. A mixed method approach was used to explore the qualitative and quantitative data. Smartphones were used to complete writing tasks on blogs. The results of the study reveal that using smartphones, combined with a TBLT approach, created learning environments which promote self-confidence and interaction with the teacher and peers. It also helped the teacher in providing individual feedback to the students, improving students’ engagement in learning tasks as well as self-expression in English.
