    Perception of school meals in Sweden: a semantic study2012In: 5th European Conference on Sensory and Consumer Research, 'A Sense of Inspiration' / [ed] Elsevier, Elsevier, 2012Conference paper (Other academic)
    Abstract [en]

    A crucial factor in man’s relationship to food is his ability to perceive flavors and aromas.  This area of study is known as sensory analysis. The ability to taste and smell is strongly related to experiences, learning and memories. The sensory pays attention to how we communicate and relate to the perceived taste quality. Taste and values are important factors in practice and a common vocabulary to express how taste is perceived is of great importance within a social group.

    The purpose of this paper is to analyze meaning and importance of sensory vocabulary for school meals within groups of students and kitchen staff by using a semantic frame model. The analysis aims at highlighting different semantic aspects of the vocabulary, such as the inherent conceptual patterns of the words, their semantic domains and the specific-general dimension. The study further aims to uncover how a semantic frame analysis could be used to expand and develop sensory vocabularies among groups of actors to communicate values and sensory qualities of school meals.

     

    Groups of students and kitchen staffs at two elementary schools and one high school in Sweden assessed the same lunch meal for the sensory domains of appearance, odor, taste and texture. The vocabulary (language and words) they used were then evaluated according to semantic frame theory.

     

    Preliminary results show that the vocabulary could be organized into different sensory dimensions such as appearance, texture, flavor, basic taste and odor. Within all dimensions, both hedonics as well as descriptive sensory descriptors was used. Furthermore, the study recognized that vocabulary used by kitchen staffs were mainly related to the technical aspects of cooking techniques.  The findings show that the conceptual profiles of the frames could suggest a way to expand the sensory vocabulary in order to actively propose and invite students to the sensory experience of food that may positively affect their meal perceptions.

    FAMM: from food to meal research on the product aspect of the meal experience2008In: Journal of foodservice, ISSN 1748-0140, Vol. 19, no 1, p. 63-68Article in journal (Refereed)
    Abstract [en]

    The Five Aspect Meal Model (FAMM) has been widely used at the Institution of Restaurant and Culinary Arts, Örebro University, Sweden, not only for developing meal services in restaurants but also for formulating research questions. The aim of the present paper was to highlight research projects focused on the product aspect of FAMM. Important research fields are the sensory quality of food and meal, and the responsibility of the restaurants and their contribution to a better welfare. Meal service, including ready meals, is a growing sector within the food industry, with important research questions concerning consumers' needs and wishes. To further develop the research on Culinary Arts and Meals Science discipline, a broad perspective on the meal is useful. Research questions based upon FAMM, where the entirety of the meal is studied, present an interesting challenge for the future.

    Vuxnas syn på sin tid som familjehemsplacerade: En studie om anknytning till familjehemsföräldrar och upplevd kontakt med socialsekreteraren2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to examine how the connection with the foster parents and the contact with the social services affects a child during a foster care placement and later in life. Furthermore, it also examines how good connection favours a foster care placement and the contact with the social services. For the study, a qualitative method was used. Five interviews took place with adults who have, at some point during their childhood, been in foster care. Parts of Bowlbys attachment theory and Antonovskys (2010) idea of KASAM was used to analyze the study’s empirics. The result shows that all adults who got interviewed in this study felt they had good relations with the foster parents and felt safe in their presence during the time they spent in foster care. Four guidelines for a good relationship between a child and their foster parents has showed to be rules, structure, commitment and affinity. Children who feel insecure with their current relations have a harder time building new relations and will have a tough time creating good relations within the foster home. The Social Service Act demands that every child in foster care shall be assigned a social secretary (2015:982). Children who has been placed in foster care needs a social secretary that they feel they can trust, this will increase the possibility of good relations within the foster home.

    Mortality after tonsil surgery, a population study, covering eight years and 82,527 operations in Sweden2015In: European Archives of Oto-Rhino-Laryngology, ISSN 0937-4477, E-ISSN 1434-4726, Vol. 272, no 3, p. 737-743Article in journal (Refereed)
    Abstract [en]

    The objective of this retrospective cohort study was to evaluate mortality rate and cause of death after tonsil surgery in Sweden. Two national registries were used, both run by The Swedish National Board of Health and Welfare, an agency of the Ministry of Health and Social Affairs. In the National Patient register all tonsil surgeries performed in Sweden from 2004 through 2011 were identified. The result from this search was matched with the National Cause of Death Register to identify all deaths that occurred within 30 days of tonsil surgery. Personal identity numbers were used to do the matching of registers. Details on the cause of death were obtained from the Swedish National Board of Health and Welfare. Two deaths were identified in 82,527 operations. Both patients were male, otherwise healthy, children under the age of five, operated due to tonsil-related upper airway obstruction/snoring with coblation technique. Cause of death was bleeding-related airway obstruction in both cases and hemodynamic failure caused by blood loss. Both deaths occurred after discharge from the hospital within the first postoperative week. No abnormal levels of analgesics were found in the postmortal investigations. Two deaths related to tonsil surgery (performed on benign indications) were identified in 82,527 operations (2004–2011) in a well-defined national population. Both deaths were due to postoperative bleeding. Based on our findings, the frequency of post-tonsil-surgery mortality in Sweden was 1/41,263, 2004–2011.

    Faktorer som påverkar upplevelser av att vara närstående till en person med cancer2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Cancer är en av nutidens stora folksjukdomar. Varje år får 10 miljoner personer runt om i världen diagnosen och år 2030 uppskattas det att 13,1 miljoner personer kommer att dö i sjukdomen. Det är inte bara den som får diagnosen cancer som drabbas utan även närstående. Syftet var att studera faktorer som påverkade upplevelser att vara närstående till en person med cancer. Metoden utgick från Polit och Becks (2012) niostegsmodell. PubMed och Cinahl valdes som databaser vid artikelsökningen. Valda artiklar granskades och analyserades enligt Polit och Becks (2012) granskningsmallar. Resultatet baserades på 11 vetenskapliga artiklar, varav fem kvalitativa och sex kvantitativa. Kategorierna som identifierades utifrån artiklarna var närståendes relation till den cancerdrabbade, kultur och religion som stöd, närståendes reaktioner, information och vardagen, vilka påvisade faktorer som avgjorde hur närstående upplevde sjukdomsprocessen. Slutsatsen visade att närstående till cancersjuka personers upplevelser av sjukdomsprocessen varierade beroende på olika faktorer. Upplevelserna framkallade både psykiska och fysiska symtom och tecken, de kunde vara både negativa och positiva.

    Att stå bredvid: En kvalitativ studie om att leva med en person som har cancer2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Cancer är en folksjukdom som ökar i dagens samhälle. Ett cancerbesked är en familjeangelägenhet och närstående blir ofta en viktig del i vården av cancerpatienter.

    Syfte: Syftet var att beskriva upplevelser av att vara närstående till en person med cancer.

    Metod: En kvalitativ, manifest innehållsanalys med en induktiv ansats utifrån biografier.

    Resultat:  Två kategorier identifierades; stärkande upplevelser och nedbrytande upplevelser. Ur stärkande upplevelser urskildes tre underkategorier; att finna ljusglimtar i vardagen, att finna kraft i gemenskap och att kämpa för försoning. De närstående upplevde ett nytt perspektiv som möjliggjorde lyckliga stunder i enkla vardagssituationer. De fann även kraft i stödet från andra medmänniskor och inom processen mot acceptans. Ur nedbrytande upplevelser identifierades tre underkategorier; att famla i mörkret, att vara den bärande väggen samt att lida nederlag. Närstående uttryckte oro för framtiden, samtidigt som de beskrev ett betungande ansvar att vara starka. De kunde därtill sörja livet innan cancer.

    Slutsats: Att leva bredvid cancer visar på åtskilliga upplevelser och själsliga utmaningar. För att kunna erbjuda adekvat vård krävs förståelse för de närståendes livssituation. En insikt i de närståendes kamp genom hälsa och lidande kan därför vara betydelsefullt för sjuksköterskor i deras yrke.

    Shoppingturism och hur detaljhandeln kan fungera som turistattraktion: -Umeås möjligheter med IKEA2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper studies the many aspects of shopping tourism. By using IKEA and the establishment of the popular retail chain in Umeå as a specific case to look at, the study will focus on determening the possibilities associated with using retail as part of the marketing for a destination. The intention is also to look at how big of a part shopping as a whole is presented when municipalities are marketing themselves. By looking at the municipality of Sundsvall aswell, the paper aims to investigate what they have benefited from having a IKEA store. This is done so that the results later can be used to draw connections to the possible situation in Umeå.

    The method chosen to establish a result for this study was by doing interviews.  These interviews was later analyzed by deviding the answers from the interviews into themes. To get a clearer view of how the municpalities had worked with retail in their marketing,  some regulatory documents was analyzed as well.

    Conflict and concord in work and family: Family policies and individuals' subjective experiences2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background This thesis explores the relationship between individuals’ subjective experiences and the welfare state setting. The research questions in focus deal with the outcomes of women’s and men’s increasing dual roles in work and family in contemporary welfare states. The studies analyse women’s and men’s subjective experiences of combining work and family, and their perceptions of fairness in the division of household work.

    Methods The thesis applies a comparative perspective where the unit of analysis is country and/or family policy model. A broad perspective with the aim to capture general patterns across a broad range of welfare states is combined with a narrower case-oriented approach. Multilevel analysis is used to analyse patterns at national as well as individual levels in the same model. Latent Class Analysis is used to capture patterns of latent dimensions with regard to the central concept of subject experiences.

    Results The results indicate that the introduction of policies aiming to promote dual roles among women and men and the articulation of gender equality can matter for individuals’ subjective experiences of work-family conflict. In dual-earner countries, the probability that a high level of conflict is counterbalanced by feelings of life satisfaction is higher than in other policy models. A class asymmetry is found when it comes to effects of policy on men’s and women’s levels of work-family conflict and work-family satisfaction; women in the working class and the salaried class are more similar when it comes to experiences of work-family conflict and satisfaction in Sweden than in Germany and the UK. The analysis also shows that perceptions of fairness in the division of housework are moderated by the institutional and normative context. The politicisation of gender equality increases the correspondence between actual share of housework performed and the perceptions of fairness in the division of housework. The effect of politicisation is more important for men’s perceptions than for women’s.

    Conclusion The thesis contributes to a deepened understanding of the relationship between policy and work-family conflict and the integration of the perspectives of role conflict and role expansion; knowledge about the ways in which both class and gender relations are structured concerning the patterns of work-family conflict and satisfaction in different policy contexts; and new knowledge about the relationship between policy and men’s – and not only women’s – perceptions of fairness in the division of household work.

    Interactions of class, gender and policy: Implications for work-family conflict and satisfactionManuscript (preprint) (Other academic)
    Abstract [en]

    The aim of this article is to explore theinteractive effects of gender, social class and public policy on men’s andwomen’s subjective experiences of work-family conflict and work-familysatisfaction. The central idea is that effects of gender and class covariatebetween different types of family policy models. Most previous comparativeresearch on the experiences of work-family conflict among women and men indifferent social contexts has assumed that class effects are similar acrosspolicy models. However, the results in this paper point to a class asymmetrywhen it comes to effects of policy on men’s and women’s levels of work-familyconflict and work-family satisfaction in three countries representing typicalcases with regard to family policy model (Germany, the UK, and Sweden). Theanalysis draws on data from the 2002 round of the International Social SurveyProgramme concerning family and changing gender roles, and shows that patternsof work-family conflict and work-family satisfaction differ among welfarestates. In Sweden women both in the working class and the salaried classexperience higher work-family conflict than men. However, these feelings ofconflict go hand in hand with correspondingly higher levels of work-familysatisfaction. In Germany class cleavages are more prominent than gender withregard to experiences of work-family conflict, while in the UK, women in thesalaried classes stand out with the highest level of work-family conflict ofall groups. In both Germany and the UK, experiences of work-family satisfactiondo not differ significantly between men and women in different classes.

    Is it fair to share? Perceptions of fairness in the division of housework among couples in 22 countries.2013In: Social Justice Research, ISSN 0885-7466, E-ISSN 1573-6725, Vol. 26, no 4, p. 400-421Article in journal (Refereed)
    Abstract [en]

    This study explores the relationship between the actual division of housework and men’s and women’s perceived fairness in this regard. The central question is how the actual sharing of housework influences the perceptions of fairness in the division of housework. It is hypothesized that the perceptions of fairness differ between policy models. In countries where gender equality has been more present on the political agenda and dual-earner policies have been introduced, people are expected to be more sensitive to an unfair sharing or division of housework. By analysing the relationship between actual division of housework and perceptions of fairness in household work for 22 countries representing different family policy models, the study takes on a comparative perspective with the purpose of analysing the normative impact of policy. The analysis draws on data from the 2002 round of the International Social Survey Programme on family and changing gender roles. The results show that in countries that have promoted gender equality through the introduction of policies with an aim to promote dual roles in work and family, both women and men are more sensitive to an unfair division of household labour. The difference between perceptions in the different policy models is greater among men than among women, indicating that a politicization of the dual-earner family is more important for men’s equity perceptions than women’s.

    Work-family conflict in the Nordic countries: a comparative analysis2012In: Journal of Comparative Family Studies, ISSN 0047-2328, E-ISSN 1929-9850, Vol. 43, no 2, p. 165-184Article in journal (Refereed)
    Abstract [en]

    The aim of this article is to examine men's and women's subjective experiences of work-family conflict in the Nordic welfare states. These countries are often considered to be frontrunners with regard to gender equality, especially regarding the provision of policies that aim to support the reconciliation between work and family life. However, previous research has produced divergent results in response to the question of whether the welfare state institutions of the Nordic countries help to reduce work-family conflict. Do supportive institutions matter, or is the household division of labour of greater importance regarding experiences of work-family conflict? Drawing on data from the 2002 module of the International Social Survey Programme, the analyses indicate that experiences of work-family conflict among Nordic men and women can be divided into three clusters: work-family balance, occupational work overload, and dual work overload. In spite of their shorter working hours, women experience higher levels of work-family conflict than men. An unfair division of housework also increases work-family conflict. In the main, experiences of work-family conflict do not differ greatly among the Nordic countries, with the exception of Finland, where the level is lower than in the other countries. This points to a difference within the Nordic welfare state regime regarding the transition towards gender equality.

    How Does Running in Minimalist Shoes Affect Injury Risk?: A Systematic Review2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Aim: The aim of this systematic review was to investigate injury risk when running in minimalist shoes compared to running in traditional running shoes. The purpose of the study was also to identify risk factors that could increase the risk of developing a running related injury when running in minimalist shoes, compared to running in traditional running shoes.

    Method: The databases PubMed, SportDiscus, ScienceDirect, CINAHL and Cochrane were searched for relevant studies. Ten studies were included in the systematic review and the quality of the studies was reviewed according to the PEDro Scale. Three out of ten studies were randomized controlled trials and seven studies were crossover trials. Five out of seven crossover trials described a randomized intervention order.

    Results: General injury risk when running in minimalist shoes compared to running in traditional running shoes was evaluated in two randomized controlled trials. One study showed a significantly increased injury risk and one pilot study showed no significant results due to a small population size. Biomechanical factors related to injury risk were assessed in two randomized controlled trials and seven crossover studies, showing that there was a significant increase in forefoot pressure, vertical loading rate and Achilles tendon load when running in minimalist shoes compared to running in traditional running shoes. There was no significant difference in rearfoot pronation when comparing the two footwear conditions.

    Conclusions: Moderate evidence shows that running in minimalist shoes increases the forefoot pressure compared to running in traditional running shoes and thereby increases the risk of developing metatarsal stress fractures. Limited to moderate evidence shows that running in minimalist shoes also increases the loading of the Achilles tendon, compared to running in traditional running shoes, which may increase the risk of developing chronic Achilles tendon pain. Starting to run in minimalist shoes, when accustomed to running in traditional running shoes, should be based on a gradual increase of training volume in order to avoid an increased injury risk.

    Automatic Transmission Power Flow Matrix Representation2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The project has worked with the function and structure of epicyclical automatic transmissions.

    The goal of the project has been to find a mathematical way of representing the transmissions

    setup and possible power flows. Furthermore the project has included the generation of all

    theoretically possible matrix representations of two simple planetary gear sets in MATLAB as

    the base for a future optimization model.

    The result of the project is a large quantity of matrix representations of the two planetary gear

    sets and their connections and shafts. The result from the MATLAB program has been verified

    by comparing the structure and the number of solutions to all manually derived setups. The result

    from the program can be considered to be complete for two planetary gears but to extend the

    analysis to more complex planetary gears and gearboxes with more than two sets, another

    method is suggested. The generation process in this project has been rather complex and time

    consuming.

    The conclusions drawn from this project is that it is possible to represent many epicyclical

    automatic transmissions in matrix form. An optimization program based on this type of matrix

    would simplify the design of new, more complex and more efficient epicyclical transmissions

    leading to more efficient vehicles.

    Key words: automatic transmission, planetary gear, matrix representation

    Modellering och analys av kuggrigg2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This technical report is a product of a bachelor thesis work for Sveriges Transmissionskluster in cooperation with the department of Machine Design at KTH. The report describes the procedure of modelling and analysing the stiffness and resonance of a gear rig, the FZG Standard Test Rig, which is to be utilized at KTH for testing hydrodynamic losses in gears. The gear rig was initially modeled to great detail in the CAD-software Solid Edge. The model was then simplified in several steps and analyzed in ANSYS with the Finite Element Method. The purpose of the analysis was to get the stiffness and resonance of the gear rig. The gear mesh was described according to a rolling sliding contact. The bearings contained in the structure were modeled as solid components with a calculated stiffness. The largest rotational deformation of the shafts was 4.5 degrees at a pre-tensioned load of 1000Nm. The stiffness in the shafts did not vary linearly and the deformation in the gear boxes did not increase in proportion to the load increase. The lowest resonance frequency obtained in the modal analysis was 136Hz which converts to 8160rpm and was attained at 50Nm. For the untensioned rig the resonance frequency was 197 which converts to 11885rpm. At maximal load, 1000Nm, the lowest calculated safety for plastic deformation was a factor of 4. The model and the analysis are based upon an existing rig that has been measured and photographed to enable the digital recreation of the rig in Solid Edge. The analysis is based upon this digital recreation and no live tests have been conducted. This report together with the CAD model, a demonstrational film of the rig’s function and the ANSYS analysis are the results of this bachelor’s thesis.

    Dynamics, Information System and Maintenance: drivers for change at the level of the individual1999Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    A lot of factors inside and outside the organisation forces the organisation and the indiviudals working in the organisation to change. The aim of this work is to get an understanding of the relationship between change, maintenance and information. To reach that aim the objectives are to examine what kind of external and internal factors there are that causes change in user demands and to see how these new demands can be handled inside the organisation. It becomes harder and harder to adapt to changes due to the fast acceleration of change, therefore it is important to become aware of what kind of factors result in new user demands and needs. Nine change factors on the organisational level were identified based on a literature study. An analysis of the differences between the organisation and the indiviudal (organism) level established a gorund for identifying factors on the level of the individual.

    Upphandling av standardsystem: en företagsstudie1998Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Vid nya systeminvesteringar blir det idag allt vanligare att standardsystem väljs framför egenutveckling av ett skräddarsytt system. Införande av ett standardsystem påverkar verksamheten i lika hög grad som införande av ett egenutvecklat system gör. Det är viktigt att upphandlingsprocessen planeras och genomförs väl.

    I takt med att standardsystemen har utvecklats så har även forskningen på området ökat. Detta har resulterat i att ett antal modeller för upphandling av standardsystem har växt fram, dels för att underlätta arbetet med att inhandla ett standardsystem, dessutom kan en modell stärka kundens förhållande till leverantören.

    Arbetets främsta mål är att undersöka hur arbetsprocessen för upphandling av standardsystem går till idag. Vad anser företag är viktigt att behandla under upphandlingsprocessen, vilka likheter finns mellan företagen och vad skiljer sig åt. I rapporten beskrivs 6 olika upphandlingssituationer. Jag har valt att intervjua företag som inte har använt sig av en modell i upphandlingsprocessen. Detta för att en jämförelse skall kunna genomföras. En jämförelse av företagens upphandlingsprocess med den process som användandet av en modell skulle ge. Den modell som jag har valt att jämföra företagens upphandlingsprocess med är Standardsystem i Verksamheten (SIV-modellen).

    Med min undersökning som grund anser jag att företag inte nödvändigtvis behöver arbeta med en standardiserad modell vid upphandling av standardsystem. Det viktiga är att arbeta strukturerat och metodiskt och planera upphandlingsprocessen väl. Detta anser jag att i stort sett alla de intervjuade företagen har gjort.

    Rapporten tar därutöver även upp standardsystem i allmänhet. Vad är ett standardsystem, vilka för- och nackdelar finns det med ett inköp av ett standardsystem. Slutligen kommenterar jag vilka erfarenheter och slutsatser som kan dras utav mitt arbete.

    This master thesis, which has been carried out at Expektra, has contributed to design, developmentand implementation of a web based interface for one of their products, Predict Demand. For theimplementation, the project has considered different methods to evaluate their prototype withfooting in human-computer interaction and interaction design. This is valuable when it comes to thedesign and further development process for general user interfaces. The project has also looked atdifferent tools and frameworks to make the implementation more efficient.The result of the design and implementation has at the end of the project been evaluated by two endusers from a reference customer for this service. Even though the number of responses was limitedand therefore of no statistical significance the answers can be analyzed and give input for furtherdevelopment of the interface.The answers from the questionnaire were positive of how the finished design turned out as well asall the different parts that were inquired about. When more customers have joined the service therecan be a new attempt with the questionnaire to be able to get a more comprehensive result.This master thesis has focused on the front-end part which means that no back-end relatedinformation will be covered. One of the early limitations that were decided was to only focus on thelatest version of the Chrome web browser.

    Abstract [en]

    A society handle on one hand uncertain, unpredictable and incalculable events and on the other hand planned, calculated and predictable occasions. In this essay, I will investigate how these events and situations that we do not know anything about are socially organized. Sweden, among other developed countries worldwide, may be an interesting field of a new upcoming discourse of security and safety. New agencies in the form of alarm centres with on-call and on-site services are popping up more often these days. Two of those agencies are analysed in this essay. Earlier research on this theme handle phenomenon such as rationality, crisis, chaos and catastrophes. Also, phenomenological sense-making studies of organizations working with these kinds of events have been gone through.

    The sociological theoretical framework of system and lifeworld, developed by Jürgen Habermas in his work of Theories of Communicative Action1 is the theoretical outset in this study. With mentioned organizations, at somewhat different domains, I have used the qualitative methodologies of semi-structural interviews and participant observations. Interpersonal verbal communication is here problematized together with technological and digital forms of communication. The result gave that some forms of systematic organized processes, but also reflexive and intuitive forms of action can explain the dichotomy of system and lifeworld in the structural middle level (meso) for investigated organizations.

    The aim was to examinehow managers, based on similar education and policy background, perceive their leadership today, and how it according to them, maybe developed in the future. The sample consisted of younger and older managers within the same organization, with diverse experience in managementand leadership roles. Data were collected by two focus groups interviews and analyzed bya thematic analysis. The results indicated that managers, regardless of age and experience, have similar views on their management role and are in general positive regardingtheir leadership, despite stressand time pressure related issues. They have also suggested similar changes for future management and leadership roles. One such suggestion is that the organization must actively work to attract additional workers in the future, in order to meet increasing competitions against other employers. Competition between employers will increase for new employees who willmake greater demands on their employers interms of working conditions and benefits.

    Insights into bunyavirus architecture from electron cryotomography of Uukuniemi virus2008In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 105, no 7, p. 2375-2379Article in journal (Refereed)
    Abstract [en]

    Bunyaviridae is a large family of viruses that have gained attention as "emerging viruses" because many members cause serious disease in humans, with an increasing number of outbreaks. These negative-strand RNA viruses possess a membrane envelope covered by glycoproteins. The virions are pleiomorphic and thus have not been amenable to structural characterization using common techniques that involve averaging of electron microscopic images. Here, we determined the three-dimensional structure of a member of the Bunyaviridae family by using electron cryotomography. The genome, incorporated as a complex with the nucleoprotein inside the virions, was seen as a thread-like structure partially interacting with the viral membrane. Although no ordered nucleocapsid was observed, lateral interactions between the two membrane glycoproteins determine the structure of the viral particles. In the most regular particles, the glycoprotein protrusions, or "spikes," were seen to be arranged on an icosahedral lattice, with T = 12 triangulation. This arrangement has not yet been proven for a virus. Two distinctly different spike conformations were observed, which were shown to depend on pH. This finding is reminiscent of the fusion proteins of alpha-, flavi-, and influenza viruses, in which conformational changes occur in the low pH of the endosome to facilitate fusion of the viral and host membrane during viral entry.

    The glycoprotein cytoplasmic tail of Uukuniemi virus (Bunyaviridae) interacts with ribonucleoproteins and is critical for genome packaging2007In: Journal of Virology, ISSN 0022-538X, E-ISSN 1098-5514, Vol. 81, no 7, p. 3198-3205Article in journal (Refereed)
    Abstract [en]

    We have analyzed the importance of specific amino acids in the cytoplasmic tail of the glycoprotein G(N) for packaging of ribonucleoproteins (RNPs) into virus-like particles (VLPs) of Uukuniemi virus (UUK virus), a member of the Bunyaviridae family. In order to study packaging, we added the G(N)/G(C) glycoprotein precursor (p110) to a polymerase I-driven minigenome rescue system to generate VLPs that are released into the supernatant. These particles can infect new cells, and reporter gene expression can be detected. To determine the role of UUK virus glycoproteins in RNP packaging, we performed an alanine scan of the glycoprotein G(N) cytoplasmic tail (amino acids 1 to 81). First, we discovered three regions in the tail (amino acids 21 to 25, 46 to 50, and 71 to 81) which are important for minigenome transfer by VLPs. Further mutational analysis identified four amino acids that were important for RNP packaging. These amino acids are essential for the binding of nucleoproteins and RNPs to the glycoprotein without affecting the morphology of the particles. No segment-specific interactions between the RNA and the cytoplasmic tail could be observed. We propose that VLP systems are useful tools for analyzing protein-protein interactions important for packaging of viral genome segments, assembly, and budding of other members of the Bunyaviridae family.

    Tick-borne encephalitis virus delays interferon induction and hides its double-stranded RNA in intracellular membrane vesicles2010In: Journal of Virology, ISSN 0022-538X, E-ISSN 1098-5514, Vol. 84, no 17, p. 8470-8483Article in journal (Refereed)
    Abstract [en]

    Tick-borne encephalitis virus (TBEV) (family Flaviviridae, genus Flavivirus) accounts for approximately 10,000 annual cases of severe encephalitis in Europe and Asia. Here, we investigated the induction of the antiviral type I interferons (IFNs) (alpha/beta IFN [IFN-alpha/beta]) by TBEV. Using strains Neudörfl, Hypr, and Absettarov, we demonstrate that levels of IFN-beta transcripts and viral RNA are strictly correlated. Moreover, IFN induction by TBEV was dependent on the transcription factor IFN regulatory factor 3 (IRF-3). However, even strain Hypr, which displayed the strongest IFN-inducing activity and the highest RNA levels, substantially delayed the activation of IRF-3. As a consequence, TBEV can keep the level of IFN transcripts below the threshold value that would permit the release of IFN by the cell. Only after 24 h of infection have cells accumulated sufficient IFN transcripts to produce detectable amounts of secreted IFNs. The delay in IFN induction appears not to be caused by a specific viral protein, since the individual expressions of TBEV C, E, NS2A, NS2B, NS3, NS4A, NS4B, NS5, and NS2B-NS3, as well as TBEV infection itself, had no apparent influence on specific IFN-beta induction. We noted, however, that viral double-stranded RNA (dsRNA), an important trigger of the IFN response, is immunodetectable only inside intracellular membrane compartments. Nonetheless, the dependency of IFN induction on IFN promoter stimulator 1 (IPS-1) as well as the phosphorylation of the alpha subunit of eukaryotic initiation factor 2 (eIF2alpha) suggest the cytoplasmic exposure of some viral dsRNA late in infection. Using ultrathin-section electron microscopy, we demonstrate that, similar to other flaviviruses, TBEV rearranges intracellular membranes. Virus particles and membrane-connected vesicles (which most likely represent sites of virus RNA synthesis) were observed inside the endoplasmic reticulum. Thus, apparently, TBEV rearranges internal cell membranes to provide a compartment for its dsRNA, which is largely inaccessible for detection by cytoplasmic pathogen receptors. This delays the onset of IFN induction sufficiently to give progeny particle production a head start of approximately 24 h.

    The cytoplasmic tails of Uukuniemi Virus (Bunyaviridae) G(N) and G(C) glycoproteins are important for intracellular targeting and the budding of virus-like particles2007In: Journal of Virology, ISSN 0022-538X, E-ISSN 1098-5514, Vol. 81, no 20, p. 11381-11391Article in journal (Refereed)
    Abstract [en]

    Functional motifs within the cytoplasmic tails of the two glycoproteins G(N) and G(C) of Uukuniemi virus (UUK) (Bunyaviridae family) were identified with the help of our recently developed virus-like particle (VLP) system for UUK virus (A. K. Overby, V. Popov, E. P. Neve, and R. F. Pettersson, J. Virol. 80:10428-10435, 2006). We previously reported that information necessary for the packaging of ribonucleoproteins into VLPs is located within the G(N) cytoplasmic tail (A. K. Overby, R. F. Pettersson, and E. P. Neve, J. Virol. 81:3198-3205, 2007). The G(N) glycoprotein cytoplasmic tail specifically interacts with the ribonucleoproteins and is critical for genome packaging. In addition, two other regions in the G(N) cytoplasmic tail, encompassing residues 21 to 25 and 46 to 50, were shown to be important for particle generation and release. By the introduction of point mutations within these two regions, we demonstrate that leucines at positions 23 and 24 are crucial for the initiation of VLP budding, while leucine 46, glutamate 47, and leucine 50 are important for efficient exit from the endoplasmic reticulum and subsequent transport to the Golgi complex. We found that budding and particle generation are highly dependent on the intracellular localization of both glycoproteins. The short cytoplasmic tail of UUK G(C) contains a lysine at position -3 from the C terminus that is highly conserved among members of the Phlebovirus, Hantavirus, and Orthobunyavirus genera. Mutating this single amino acid residue in G(C) resulted in the mislocalization of not only G(C) but also G(N) to the plasma membrane, and VLP generation was compromised in cells expressing this mutant. Together, these results demonstrate that the cytoplasmic tails of both G(N) and G(C) contain specific information necessary for efficient virus particle generation.

    Generation and analysis of infectious virus-like particles of uukuniemi virus (bunyaviridae): a useful system for studying bunyaviral packaging and budding2006In: Journal of Virology, ISSN 0022-538X, E-ISSN 1098-5514, Vol. 80, no 21, p. 10428-10435Article in journal (Refereed)
    Abstract [en]

    In the present report we describe an infectious virus-like particle (VLP) system for the Uukuniemi (UUK) virus, a member of the Bunyaviridae family. It utilizes our recently developed reverse genetic system based on the RNA polymerase I minigenome system for UUK virus used to study replication, encapsidation, and transcription by monitoring reporter gene expression. Here, we have added the glycoprotein precursor expression plasmid together with the minigenome, nucleoprotein, and polymerase to generate VLPs, which incorporate the minigenome and are released into the supernatant. The particles are able to infect new cells, and reporter gene expression can be monitored if the trans-acting viral proteins (RNA polymerase and nucleoprotein) are also expressed in these cells. No minigenome transfer occurred in the absence of glycoproteins, demonstrating that the glycoproteins are absolutely required for the generation of infectious particles. Moreover, expression of glycoproteins alone was sufficient to produce and release VLPs. We show that the ribonucleoproteins (RNPs) are incorporated into VLPs but are not required for the generation of particles. Morphological analysis of the particles by electron microscopy revealed that VLPs, either with or without minigenomes, display a surface morphology indistinguishable from that of the authentic UUK virus and that they bud into Golgi vesicles in the same way as UUK virus does. This infectious VLP system will be very useful for studying the bunyaviral structural components required for budding and packaging of RNPs and receptor binding and may also be useful for the development of new vaccines for the human pathogens from this family.

    Echo cancellation in ADSL modems2001Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This Master Thesis report presents a way of enhancing the performance of an ADSL (Asymmetric Digital Subscriber Line) system by canceling out transmitter echoes that occur in the coupling between the AFE (Analog Front End) and the phone lines. This new way of canceling the transmit echoes applies to all systems where the transmitted signal can be modeled by a random noise signal. The idea is to cancel out the transmit echoes in the analog domain before the ADC (Analog Digital Converter) in order to increase the sensitivity of the receiver. With this echo canceling method the echo suppression of the transmitted signal can come close to what is theoretically possible. The development and simulations are done using a Matlab model of the AFE. To verify the model and show that the performance expectations were fulfilled the echo canceller was implemented in a real time system based on four ADSP-21160 DSPs (Digital Signal Processors) from ADI (Analog Devices). The issues involved with a migration from a simulation model to real systems are also considered.

    Abstract [en]

    Background: Research has shown that despiteacademic progress in fields of pain physiology and analgesic/anaesthetic medicine, patients are still experiencing postoperative pain. The anaesthetic nurse play a central role in the prevention, discovery and treatment of postoperative pain. Motive: To the authors knownledge there is no Swedish study that examines anaesthetic nurses´experience of care and treatment for patients with pain in hospital recovery units. Research in this area could contribute to improvements in the care of postoperative patients. Aim: To document anaesthetic nurses´experiences and challenges in caring for patients´postoperative pain in hopspital recovery units. Methods: A qualitative semi-structured interview methodology was adopted in this study. Interviews were conducted in autumn 2018. Interview subjects were 10 anaesthetic nurses´who work both in recovery and operation units. A qualitative analysis was then applied to the data collected. Result: 3 categories and 11 sub-categories were identified. These 3 categories were: prediction and proactivity, attentiveness and perception and administration of medicine and teamwork. The categories reveal som of the challenges the anaesthetic nurse face in the prevention, discovery and treatment of postoperative pain. Discussion: There are several challenges that anaesthetic nusres´are well aware of and which effect their capacity to treat pain. These challenges are dependent on the specific needs of patients, patients prerequisites as well as organisational structure. As such, staff responsible for patient care should be attentive to patients´specific needs as well as plan perioperative treatment/care in consultation with the patient. This would achieve the best patient outcomes as well as giving the perioperative staff the ability to predict and prevent postoperative pain trough treatment. Conclusion: This study shows that anaesthetic nurses´do their upmost to reduce postoperative pain. Nurses were aware of challenges. These may be avoided by adopting a more individualised care approach. Keywords: Anaesthetic nurse, postoperative pain, pain relief, experiences, nursing.

    Hiding from intracellular pattern recognition receptors, a passive strategy of flavivirus immune evasion2011In: Virulence, ISSN 2150-5594, E-ISSN 2150-5608, Vol. 2, no 3, p. 238-240Article in journal (Refereed)
    Abstract [en]

    Tick-borne encephalitis virus (TBEV) is a medically important flavivirus in Europe and Asia, causing meningitis and encephalitis in thousands of people annually. Despite its relevance for public health, the interaction of TBEV with the type I interferon (IFN) system is poorly characterized. Induction of these antiviral cytokines is normally triggered by cytoplasmic recognition of viral signature molecules such as double-stranded (ds) RNA. In a recent paper, we showed that TBEV infection leads to formation of intracellular membrane vesicles which protect the viral dsRNA from cellular recognition. This delays the onset of antiviral IFN production sufficiently enough for an unhindered release of progeny viruses over 24 h. Thus, TBEV has evolved a stealth strategy to outrun the antiviral IFN response.

    Abstract [en]

    Architecture is a stage for life. It creates prerequisites, shapes possibilities. It has a potential to empower whomever it is intended to support. This project focuses on children and their needs in order to examine how having a specific intended subject can contribute to the development of architecture and challenge preconceived notions.

    The aim has also been to explore, on a larger scale, how a building can act to influence its surroundings in an urban context - how intentions can be translated, and how the architecture’s intended legibility can be seen as a form of generosity. 

    The project takes a clear stand in stating that undefined space or buildings that aim to be ‘good for everyone’ also end up being ‘unsuitable for everyone’. So-called ‘flexible buildings’ also entail certain limits. Architecture that is more specifically programmed (and more precise about the intended subject and how space is expected to be used) can provide more value - not to everyone, perhaps, but to the intended subject.

    There exist a few “general truths” about what is needed in a building for pre-school activities. At the same time, the needs and abilities of a two-year-old and a four-year-old differ greatly. On top of this, the activities the building is expected to support vary during the day. Throughout the process the intention has been to consider and integrate all these challenges. 

    To be able to work with the concept of ‘specificity’ it was a vital part of the process to interview pre-school staff and subsequently translate the acquired information about interests, needs, and common activities of the different age-groups into concrete spaces. 

    Another aspect that made it possible to work with this theme was the construction concept, which is based on a grid, that creates the framework - a strict structure, as a base from which to then work with the more specific parts of the project within. 

    The result, this pre-school, is divided into four age-groups and eight departments, or units. All the units are based on the same idea about procession and routine, with fundamental requirements included (such as being able to have a good overview of the entire unit and, at the same time, be able to divide spaces and close off certain parts). 

    Each unit is fine-tuned according to the age of the children. These adjustments are done mainly by exploring the benefits of changing the scale of rooms and objects within rooms - also taking into consideration relevant activities and needs - as well as the children's current abilities, since the building has a potential to assist the teachers not only by supporting communication and cooperation  but also by enabling the children to do as much as possible for themselves - which also benefits their sense of independence. Another positive outcome of dividing the building into smaller units, besides being able to perform this ‘fine-tuning’, is that it gives each child a possibility to freely explore within its own ‘home’.

    To make sure the experience of each room is distinct from the next (which was considered important partly because the project recognises the benefit of children associating rooms with certain activities) different materials are used within the building’s frames not only for their functional purposes but also to strengthen this impression of dissemblance. Further, the construction allows for a play with differences in ceiling height (and sometimes a slight sloping of the floor) - a variation within the system that also integrates the need for daylight. It was important that the details consistently support general intentions.

    Lastly, much attention has been paid so that these details and the legibility don’t cross the line of becoming controlling and actually contribute to offering opportunities for the children to test boundaries, explore, and develop their way of relating to their surroundings.

    Gene Expression in Caenorhabditis elegans Fed Bacteria Pre-treated with Metal Contaminated Soil Leachates and Lab Metal Mixture2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The accumulation of heavy metals in the environment mainly from anthropogenic sources can be harmful to organisms. Humans, as well as many organisms are primarily exposed to heavy metals through their food source, and this can have seriously damaging effects. This study used Caenorhabditis elegans to determine the effects of feeding on bacteria exposed to heavy metal soil leachates by analysing their gene expression. The contaminated soils were collected near a glass factory in Sweden and their effect on C. elegans was compared to a lab prepared metal mixture of a similar concentration. Of the genes 16 evaluated, 8 showed a significant response when exposed to heavy metals. Sample site 1 induced up regulation in cdr-1 and cyp-35A2, and down regulation in hsp-70, hsp-16.2, and hsp-16.48. Sample site 2 induced up regulation in ftn-1 and cyp-35A2, and down regulation in mtl-1, hsp-70, hsp-16.2, and hsp-16.48. Sample site 3 induced up regulation in mtl-1, cdr-1, gst-4, and cyp-35A2. Finally, the metal cocktail induced up regulation in only mtl-1 and gst-4. The exposure of C. elegans to heavy metals through their food source did not show any signs of lethality but some of the key genes were certainly affected. This implies that the high levels of metals present in the soil leachates caused gene dysregulation in C. elegans to cope with the resultant stress. The difference between the stress response of the soil leachates and metal cocktail can be attributed to the complexity of the environmental samples which is comprised of several other components apart from metals.

    Skolsköterskors erfarenheter av hälsofrämjande arbete med överviktiga barn2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Abstrakt

    Introduktion: Övervikt och fetma är ett snabbt växande problem som kryper allt längre ner i

    åldrarna, och kan innebära många hälsorisker, såväl fysiska som psykiska. Barn med övervikt

    och fetma löper stor risk att förbli överviktiga även i vuxen ålder. Skolhälsovården spelar en

    betydande roll i arbetet mot övervikt. Syfte: Att beskriva skolsköterskors erfarenheter av

    hälsofrämjande arbete med överviktiga barn. Metod: Individuella semistrukturerade

    intervjuer med åtta skolsköterskor genomfördes. Materialet analyserades med hjälp av

    kvalitativ innehållsanalys. Resultat: Analyserna resulterade i fyra kategorier och tolv

    underkategorier. Rådgivning, stöd och att göra barn och familjer delaktiga tillhör kärnan i

    skolsköterskans hälsofrämjande arbete med överviktiga barn. Föräldrarna kunde upplevas

    vara både ett hinder och en tillgång i arbetet. Slutsats: Skolsköterskan behöver vara en god

    samtalspartner, och erbjuda stöd till både elever och föräldrar för att arbetet mot övervikt ska

    bli framgångsrikt. Tydliga riktlinjer förenklar skolsköterskans arbete, och underlättar

    samarbetet med andra yrkeskategorier.

    Behavioral and neuroendocrine correlates of selection for stress responsiveness in rainbow trout - a review2005In: INTEGRATIVE AND COMPARATIVE BIOLOGY, Vol. 45, no 3, p. 463-474Article in journal (Refereed)
    Abstract [en]

    In rainbow trout the magnitude of the cortisol response to stress shows both consistency over time and a moderate to high degree of heritability, and high responding (HR) and low responding (LR) lines of rainbow trout have been generated by individual selection for consistently high or low post-stress cortisol values. Using 2nd and 3rd generation fish, we tested the hypothesis that differential stress responsiveness is associated with behavioral alterations in the HR-LR trout model. LR fish showed a tendency to become socially dominant, a rapid recovery of food intake after transfer to a novel environment, and a reduced locomotor response in a territorial intrusion test. Furthermore, stress induced elevation of brain stem and optic tectum concentrations of the monoamine neurotransmitters serotonin, dopamine, and norepinephrine and their metabolites suggests that both synthesis and metabolism of these transmitters were elevated after stress to a larger degree in HR than in LR trout. A divergent pattern was seen in the hypothalamus, where LR fish displayed elevated levels of 5-hydroxyindoleacetic acid (a serotonin metabolite) and 3-methoxy-4-hydroxyphenylglycol (a norepinephrine metabolite). Thus, selection for a single trait, cortisol responsiveness, in rainbow trout is associated with concurrent changes in both behavior and central signaling systems. The apparent parallel to genetically determined stress coping styles in mammals, and the existence of similar trait associations in unselected populations of rainbow trout, suggests an evolutionarily conserved correlation between multiple traits. Continuing studies on the HR and LR trout lines are aimed at providing the physiological and genetic basis for new marker-assisted selection strategies in the rapidly developing finfish aquaculture industry, as well as increased knowledge of the function and evolution of central neuroendocrine signaling systems.
