    Evaluation of the Mother-to-Infant relation and feeling scale: Interviews with first-time mothers' for feelings and relation to their baby three days after birth2012In: International Journal of Nursing and Midwifery, ISSN 2141-2456, Vol. 4, no 1, p. 8-15Article in journal (Refereed)
    Abstract [en]

    Mothers’ perception of their relationship with their baby might affect sensitive parenting. This study aimed to explore first time mothers’ feelings for and their relation to the baby associated with how they responded to the "mother to infant relation and feelings (MIRF) scale" as a step in the validation process of the scale. Interviews with ten first-time mothers, three days after birth, were performed, using open questions followed by questions directly from the MIRF scale items. An inductive and deductive approach inspired by the "Think aloud" method guided the study. Results describe main category; New mothers bewilderment and anticipation which contained four categories; Natural and great but mixed, Maternal instinct and kinship, Ability and expectations and Not yet for real. When mothers responded to MIRF scale items they describe talking to their baby which they did not in their open answers. Answering the MIRF scale helped mothers in differentiating between their own mixed feelings of becoming mothers and their relation to and feelings for the baby. The MIRF scale appears valid in reflecting important aspects of mothers’ feelings for and relation to their baby. The MIRF scale could be used in research and when evaluating care routines as well as in dialogue with new mothers to support mother-to-infant interactions.

    Women's Experiences of Midwifery Support during Pregnancy A step in the Validation of the Scale: "The Mother Perceived Support from Professionals"2015In: Journal of Nursing & Care, ISSN 2167-1168, Vol. 4, no 2, article id 1000241Article in journal (Refereed)
    Abstract [en]

    Background: Pregnancy can be physically and emotionally stressful for the parents, which means they need adequate professional support. Easy-to-use, validated scales are important in order to develop professional support in Antenatal care as well as in research.

    The aim: Our aim was to illuminate pregnant women’s experience of professional support at the Antenatal care, in relation to the Mother-Perceived-Professionals-Support (MoPPS) scale.

    Method: A qualitative study design using the method “Think aloud” with both inductive and deductive approaches, was used. Five first-time mothers were interviewed with open questions followed by questions related to the MoPPS scale items. Data was analyzed using inductive and deductive qualitative content analyses.

    Results: The inductive analysis resulted in one theme: “Professional support from midwives made women created a feeling of security and unique or rejected and lonely during pregnancy” and three categories: “Continuity and competence”, “Perceiving trust or not” and “Parental groups or individual visits”. The deductive analysis described the mothers’ understanding of each item. However, coherence between the inductive and deductive analyses varied and the MoPPS-scale needs development.

    Conclusion: The result shows that women's experience of professional support affects their sense of feeling safe or lonely during pregnancy. Important for midwives were to meet the women’s unique individual needs. The MoPPS scale was considered to be relevant and easy to understand, but it needs development to include questions about continuity, parental groups and the perception of midwives’ competence, which all were important for the women during their pregnancies.

    Clinical implications: To offer adequate professional support for women during pregnancy, midwives need to meet the women’s unique individual needs with both medical and supportive knowledge.

    An exploration and description of student midwives' experiences in offering continuous labour support to women/couples2008In: Midwifery, ISSN 0266-6138, E-ISSN 1532-3099, Vol. 24, no 4, p. 451-459Article in journal (Refereed)
    Abstract [en]

    Aim: to explore and describe the student midwife's experiences in offering continuous labour support.Design: a qualitative research design was chosen. Each student midwife offered continuous labour support to five women/couples and wrote narratives about each of these occasions. Written narratives from 11 student midwives were analysed using qualitative content analysis.Findings: when student midwives offer continuous labour support to women/couples, they tyr to establish rapport. When this works, their presence, their sense of confidence and their ability to offer reassurance increase. If establishing rapport does not work, students experience a sense of powerlessness, a need for reassurance and a lack of confidence. Key conclusions: offering continuous labour support to women and/or their partners made the students aware of the importance of establishing rapport, and it made them realise the impact that their mere presence in the room could have. The students had a need for reassurance which could hamper their efforts to establish rapport. Experiencing a lack of confidence made students focus more strongly on their clinical skills and on their perceived role as a student midwife. Implications for practice: this study can initiate discussions about how student midwives learn to be supportive, as well as about the role models that students encounter during their clinical training in Sweden.

    Professional Support in Pregnancy Influence Maternal Relation to and Feelings for the Baby after Cesarean Birth: An Intervention Study2012In: Journal of Nursing and Care, ISSN 2167-1168, Vol. 1, no 4, p. 112-Article in journal (Refereed)
    Abstract [en]

    Background: Cesarean birth may negatively affect mother-infant interactions, while professional support may positively affect these interactions. The aim of this study was to evaluate the effects of a process-oriented training program for antenatal midwives and postnatal nurses on first time mothers’ perceptions of professional support and on their relation to and feelings for their baby after a cesarean or a normal birth. Methods: An intervention through process-oriented training for health professionals regarding professional support in childbearing was conducted between 1999 and 2003. Ten municipalities were paired and within each pair, randomly assigned to intervention (five) or control (five) municipality. Mothers having caesarean (n=94) or normal birth (n=301) were included. Mothers received routine care (Control Group=CG) or care from health professionals having received training (Intervention Group=IG). The mothers answered questionnaires three days, three and nine months after birth. Factor analysis identified three factors: “Taking in baby,” “Confidence in relation to baby,” and “Feelings for baby.” Results: Mothers in the IG with cesarean birth reported more positive for the “Taking in baby” factor (p=0.002) three days after birth, more positive for the “Confidence in relation to baby” factor (p=0.004) and for the “Feelings for baby” factor (p=0.004) nine months after birth compared to Mothers in the CG. Mothers in the IG reported stronger professional support from health professionals compared to CG. Conclusion: Our result suggests that improved professional support during pregnancy may buffer negative effects of caesarean birth for first-time mothers in relation to and feelings for the baby.

    Comparing the use of article numbers to alternate information syntaxes2013In: Proceedings of NES 2013, 45th Nordic Ergonomics & Human Factors Society conference, Iceland, August 2013, 2013Conference paper (Refereed)
    Abstract [en]

    Using article numbers as identifiers in industry is a well-established practice. However, previous investigations have indicated, although failed to confirm, shortcomings in this tradition when used in human based assembly. This paper will report findings from an experimental study where subjects were asked to perform a reaction test designed to test the response to different types of syntaxes. These syntaxes where article numbers (control), symbols, and names of famous figures. Results show that subjects were able to significantly faster identify a trigger and respond accordingly when dealing with triggers with semantic content (symbols and names) than with article numbers.

    Kontextuell analys av monteringsbana på Volvo Powertrain i Skövde2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Kontexten har en stor inverkan på en produkts användbarhet och på utförande av arbete. Både den sociala och den fysiska kontexten kan leda till kraftiga problem i form av kognitiv överbelastning och i slutändan påverka hur en montör utför sitt arbete. Studien har undersökt hur den fysiska och den sociala omgivningen påverkar arbete och vilka möjligheter som kontexten ger användaren att hantera sin kognitiva belastning. Undersökningen har genomförts som en fallstudie på Volvo Powertrain och resultatet pekar på flera faktorer som samverkar och kan leda till att montörerna monterar fel detaljer. För att reducera den kognitiva belastningen hos montörer föreslås ett antal åtgärder som kan stödja montören i sitt informationsbeteende.

    Presenting Information in Manual Assembly2011Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Ever since industrialization, manufacturing companies have competed with each other in trying to make the best and the cheapest product and the automotive industry is definitely no exception. The ‘arms race’ between truck and car manufacturers has pushed manufacturing technology and production practice to where it is today. However, whereas companies have traditionally competed with the engineering excellence and technology of their products, the human effort in production is often neglected. After all, there are still many tasks that require the flexibility and intelligence of a human worker.

    This thesis focuses entirely on the information context of assembly workers. It investigates and discusses their general information behaviour in terms of information need, syntax of information, information sources and technology as well as basic cognitive abilities used to utilize information such as attention and memory. The thesis presents relevant literature on the subject of information behaviour and pinpoints potential hazards of information design in manual assembly. It also identifies three hypotheses that suggest improved productivity and quality of work as a result of certain changes in the information landscape. One hypothesis deals with the layout of information, a second deals with the syntax used to identify parts and a third deals with the information medium used to convey information.

    Analysis of empirical data gathered shows, among other things, that using unstructured and batched information favours productivity of work; using a syntax with semantic content as opposed to traditional article numbers without any semantic content also improves productivity of work; and using a mobile information unit betters the quality of work.

    The purpose of the thesis is to present the beginnings of a road map towards the greater understanding of information presentation in manual assembly. As previous research on this application area has been scarce, it draws upon existing theories found in other sciences, primarily cognitive science and its applications such as Human-Computer Interaction (HCI), information theory and human error.

    Triggers, Entry Points, and Affordances: How to Improve Their Cognitive Congeniality2006Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    At the core of this thesis lies the concept of triggers and how a trigger’s general purpose is to raise attention to something. We discuss the similarities of triggers, entry points, and affordances in terms of medium dependency and information value, and how they can co-exist. As a basis of our trigger discussion we consider active and passive attention along with the use of tools as triggers. A number of problems are identified in trigger use, including continuous or discrete triggers and information value. Finally, suggestions are made regarding the handling of triggers, entry points, and affordances from a designer’s point of view. We discuss and suggest that triggers and their contextual elements can be handled and designed on the basis of their type, information demand, cognitive congeniality, and characteristics.

    Key words: Trigger, entry point, affordance, cognitive congeniality, attention, task transformations, information demand, medium dependency, information value.

    Using Mobile Information Sources to Increase Productivity and Quality2010In: Proceedings of the 3rd Applied Human Factors and Ergonomics (AHFE) International Conference / [ed] Gavriel Salvendy, Waldemar Karwowski, Louisville: AHFE International , 2010Conference paper (Refereed)
    Abstract [en]

    This paper presents an experimental study made on the use of different kinds of information sources in manual assembly. The general idea is that only the necessary information should be presented to the worker and it should be presented where and when the worker needs it as this is believed to both save time and unload cognitive strain. To account for the latter two aspects of this thought, where and when, this paper investigates the use of a handheld unit as an information source in manual assembly. Having a mobile information system, such as a Personal Digital Assistant (PDA), that can be carried with you at all times, as opposed to a stationary one, such as a computer terminal, is hypothesized to greatly improve productivity and quality. Experimental results show that the use of a PDA significantly improves quality whereas productivity does not significantly improve.

    Syntax and Sequencing of Assembly Instructions2012In: Advances in Usability Evaluation: Part II / [ed] Francesco Rebelo & Marcelo M. Soares, CRC Press, 2012, p. 266-275Chapter in book (Refereed)
    Abstract [en]

    Minimalism of design is a concept often found in Human-computer interaction (HCI). It is a concept that emphasizes the presentation of as little information as possible to reduce the perceptual strain and visual search of the subject. However, in a manufacturing context, such as in manual assembly, state of the art information presentation is rarely minimalistic. Rather, organizations tend to push out as much information as possible without necessarily concerning themselves with how this information is presented to, or perceived by, the worker. This leads to a situation that is far from ideal from an HCI perspective, likely to reduce human performance and wellbeing, in turn negatively affecting overall production system performance. Obviously, there are several potential ways of addressing this issue. Perhaps the most evident way is to simply reduce the amount of information that is presented and only present the essentials. This paper will investigate and discuss how information presentation can be minimized without reducing the information content through information syntax and layout.

    Information Presentation in Manual Assembly – A Cognitive Ergonomics Analysis2008In: Ergonomics is a lifestyle = Vinnuvistfræði er lífstíll: NES 2008 : abstracts, Kópavogur: Vinnuvistfræðifélag Íslands , 2008Conference paper (Refereed)
    Abstract [en]

    In current practice, information is often presented to the operators under the false belief that more information leads to better quality. However, one must consider the cognitive capacity limitations of the human operator and design information systems based on these constraints. Important questions include what medium to use; audio, visual, paper based or computer screen systems? Also the syntax in terms of symbols and text, together with information content and the formatting of the system are important factors that will require much focus to result in a good information system. The paper describes a case where paper-based assembly instructions of a major automotive company have been studied, focusing on information design and cognitive ergonomics in information seeking behaviour. Within the case study, the paper-based information system has been evaluated with two focuses: automatic information behaviour (automatism) and consistency of information presentation in the operator graphical user interface (GUI). It is suggested that systems that do not offer clear and easy-to-find entry points to information will eventually cause quality issues in production.

    Applying cognitive science to digital human modelling for user centred design2012In: International Journal of Human Factors Modelling and Simulation, ISSN 1742-5549, Vol. 3, no 1, p. 90-106Article in journal (Refereed)
    Abstract [en]

    To build software which, at the press of a button, can tell you what cognition-related hazards there are within an environment or a task, is probably well into the future if it is possible at all. However, incorporating existing tools such as task analysis tools, interface design guidelines and information about general cognitive limitations in humans, could allow for greater evaluative options for cognitive ergonomics. The paper discusses previous approaches to the subject and suggests adding design and evaluative guiding in digital human modelling that will help a user with little or no knowledge of cognitive science to design and evaluate a human-product interaction scenario.

    The effect of information mobility on production quality2014In: International journal of computer integrated manufacturing (Print), ISSN 0951-192X, E-ISSN 1362-3052, Vol. 27, no 2, p. 120-128Article in journal (Refereed)
    Abstract [en]

    This article investigates the use of a hand-held unit as an information source in manual assembly. Having a mobile information system, such as a Personal Digital Assistant (PDA), that can be brought at all times, as opposed to a stationary one, such as a computer terminal, is hypothesised to increase the information range and thus improves assembly performance. The increased information range is argued to be due to assembly workers employing a cost-benefit strategy, where the cost of gathering information is compared with the assumed benefit of it. This article reports empirical data comparing the use of a mobile information carrier with a traditional stationary computer, and results show that the use of a PDA significantly improves quality, whereas productivity does not significantly improve quality. © 2013 Copyright Taylor & Francis.

    Distributed cognition at work - A systemic perspective on human based manufacturing2015In: Proceedings of ICMR 2015 / [ed] Linda Newnes, Aydin Nassehi & Vimal Dhokia, Bath, UK: University of Bath , 2015, p. 195-200Conference paper (Refereed)
    Abstract [en]

    Cognitive science is becoming increasingly central within human factors & ergonomics and, since at the same time, there has long been a call for a more systemic perspective in the area with a somewhat wider unit of analysis, this paper argues that the theoretical framework of distributed cognition would greatly benefit the area. It would offer a more complete understanding of the user within a greater context, be it social, cultural or materialistic. This paper aims to characterize and analyse the domain of manufacturing as a complex socio-technical system from a distributed cognition perspective; focusing on the use, mediation and integration of different forms of representations, tools and artefacts in this domain.  The paper further proposes and exemplifies benefits of using a distributed cognition framework in the manufacturing domain as studied by human factors and ergonomics.

    Initial development of a cognitive load assessment tool2014In: Advances in Cognitive Engineering and Neuroergonomics / [ed] Kay Stanney & Kelly S. Hale, AHFE , 2014, p. 223-232Conference paper (Refereed)
    Abstract [en]

    Interest in cognitive or mental workload has over the last couple of years increased drastically from a manufacturing application perspective.  More and more, people are becoming aware of the cognitive limitations that may have great impact on production outcome. The more easily observable area of physical ergonomics has been successfully investigated for a long time and it would seem as though focus has broadened to also include cognitive ergonomics. Considering the effects that a large cognitive load has on human performance, knowledge regarding the role of the cognizing human in a manufacturing environment could potentially have significant effect on production outcome (i.e. quality and productivity). With this in mind, developing and using methods and tools for assessment of the cognitive burden associated with particular tasks or workstations should be and is of substantial interest to the manufacturing industry. Whatever assessment methods exist in the scientific literature today are almost exclusively expert tools where significant expertise in the area of cognitive ergonomics/psychology/science is required. This paper reports parts of the development process and initial version of a non-expert tool for assessment of cognitive load in manual production environments, primarily manual assembly.

    CLAM – A method for cognitive load assessment in manufacturing2017In: Advances in Manufacturing Technology XXXI / [ed] Gao, J., El Souri, M., Keates, S., Amsterdam: IOS Press, 2017, Vol. 6, p. 114-119Conference paper (Refereed)
    Abstract [en]

    The increasing complexity and demands of assembly operations in manufacturing has been shown to lead to increased cognitive load in assembly workers. Previous work has outlined the complexity of an assembly worker’s situation both in terms of difficulty and speed of work and there have been a few attempts at creating frameworks and methods for understanding the key aspects of what creates increased cognitive load. This paper presents a tool for assessing cognitive load in manufacturing, primarily assembly. The paper presents the method and an accompanying tool as well as some insights derived from this method development. The intended contribution of the work is to make a difference in reducing the cognitive load of assembly workers on the shop floor, thus focusing the development on applicability and usability of the tool in practice.

    On the development of a method for cognitive load assessment in manufacturing2019In: Robotics and Computer-Integrated Manufacturing, ISSN 0736-5845, E-ISSN 1879-2537, Vol. 59, p. 252-266Article in journal (Refereed)
    Abstract [en]

    The increasing complexity and demands of assembly operations in manufacturing has been shown to lead to increased cognitive load in assembly workers. Previous work has outlined the complexity of an assembly worker's situation both in terms of difficulty and speed of work and there have been a few attempts at creating frameworks and methods for understanding the key aspects of what creates increased cognitive load. This paper presents the development of an analytic method, denoted CLAM (Cognitive Load Assessment for Manufacturing), and a tool for assessing cognitive load in manufacturing, primarily assembly. It outlines the journey of the development as well as discusses and problematizes relevant meta-methodological issues paired with method development. The intended contribution of the work is to make a difference in reducing the cognitive load of assembly workers on the shop floor, thus focusing the development on applicability and usability of the tool in practice. With this purpose in mind, focus of the method development has been on the practitioners, i.e. the method should not require any expert knowledge to be applied. The CLAM method and accompanying documentation such as a handbook containing instructions towards using the method and interpreting the results, is available in an online tool.

    Embodied Interactions in Cognitive Manufacturing2020In: Advances in Neuroergonomics and Cognitive Engineering: Proceedings of the AHFE 2019 International Conference on Neuroergonomics and Cognitive Engineering, and the AHFE International Conference on Industrial Cognitive Ergonomics and Engineering Psychology, July 24-28, 2019, Washington D.C., USA / [ed] Hasan Ayaz, Springer, 2020, p. 419-426Conference paper (Refereed)
    Abstract [en]

    This paper presents a discussion on the role of embodied interaction with a basis in social embodiment effects and how they can be viewed in light of manufacturing ergonomics. The social embodiment effects are four statements, grounded in empirical findings, which highlight the interplay of social stimuli, embodied responses, and cognitive processing. They suggest and base an argument for how embodiment is central to cognitive processing, how bodily states interact extensively with cognitive states, and ultimately how embodied interaction is ubiquitous in human cognition. The paper further presents a view on how human based manufacturing can be studied in light of this argument, exploring other areas where social embodiment has been further researched, with an aim to suggest examples of where social embodiment effects might be found in manufacturing ergonomics and form a basis for future investigations.

    Modified pluralistic walkthrough for method evaluation in manufacturing2015In: Procedia Manufacturing, ISSN 2351-9789, Vol. 3, p. 5139-5146Article in journal (Refereed)
    Abstract [en]

    This paper presents a mixed evaluation design including quantitative and qualitative datain order to validate the scope, validity, and reliability of a recently developed CLAM method and tool. A central part of the evaluation was the use of a modified pluralistic walkthroughthat was created to better suit the industrial domain. The evaluation of CLAM was performed in a demonstration factory focusing on manufacturing of street scooters and electric pedal cars. The modified walkthrough was conducted on the shop floor, during on-going assembly, which stresses the representativeness of a real-world setting of manufacturing. The modified pluralistic walkthrough functioned accurately as an evaluation method of CLAM and the exhaustive comments and data from the user representatives were very beneficial. The quantitative results show convicting evidence of CLAM’s utility for assessing cognitive load while the qualitative results indicate that some modifications have to be made in order to enhance the actual tool in order to avoid misinterpretations resulting in misleading outcomes.

    Närståendes erfarenheter av att leva nära en svårt sjuk och döende person i hemmiljö: En studie av självbiografier2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Today it´s more common that next of kin´s take care of seriously ill an dying family members in their home. Nurses often encounter these relatives, and feel that healthcare doesn’t care enough about the next of kin’s possibilities and knowledge. The caregivers often focus on the ill person and forget the needs of the next of kin. Aim: The aim of this study was to highlight next of kin´s experiences of living close to a seriously ill and dying person in their domestic environment. Method: The used method was a study of autobiographies. The analysis was performed with a narrative method. Result: From the analysis five categories emerged life changes, vulnerability and courage to live here and now with ten subcategories. Conclusion: Palliative care in the home requires that caregivers are more aware of the next of kin’s needs and how to make use of their resources.

    Abstract [en]

    Study: Degree project in master education, Advanced level, 15 ECTS,University of SkovdeTitle: Education, relations and empowerment – a study of educational support in adult educationNumber of pages: 44Author: Thorén AnnaTutor: Maivorsdotter, NinithaDate: August, 2014In every generation of young adults in Sweden there are 20 % who never pass their high school exam (Sveriges Kommuner och Landsting, 2012). This tends to have a negative effect on their future adult life, both economically as well as socially. In Sweden their is a well established, national, municipally arranged, adult education which gives a second chance to study for some of these young adults. The purpose of this collection of case studies (Flyvbjer, 2006) is to analyse and shed some light on the social and educational factors that might benefit these adult students to achieve their goals and to empower themselves (Lightfoot, 1985). It is by using Deweys holistic approach to human language and experience and combining external and internal life, that the interviews was collected from three students who attend some additional, educational support. The analysis of the material was executed in five steps and following the method of content analysis (Kvale, 1997). In my results chapter I present excerpts and analysis grouped under five thematic headlines;1. School as the setting for social identity making. 2. Socio-economical factors and flexibility3. School as a positive community. 4. Relations building on feedback and mutual respect.5. Focusing on education and empowerment.

    Välbefinnande och Känsla av sammanhang bland flickor i skolvardagen (ÅR 6)2011Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish national survey "School children's health habits" have since 1985 asked children "What do you think about school these days?". School satisfaction decreases with age and unlike many other questions there are different views from boys 'and girls on this matter. Most obvious in the youngest age group, where girls more often say they feel very well at school (Swedish children's health habits, FHI 2005). In this study eight 12-year-old Swedish school girls from a small town in the west of Sweden describe their feelings about school. My method is to determine their SOC-value through a survey (Margalit & Efrati, 1996) based on Antonovsky's questionnaire for measuring Sense of Coherence (Antonovsky, 1987) and then interview them individually on the subjects of well-being, flow, and praise in school. They may talk freely about these topics and describe their feelings about different aspects of school. By assembling the different parts in the result an illustration of girls' well-being in the school setting is formed.

    Faktorer som kan leda till övervikt och fetma hos mammor och barn med låg socioekonomisk status2014Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Övervikt och fetma är ett globalt, betydande växande hälsoproblem som verkar vara ett särskilt problem i familjer som lever under låga socioekonomiska förhållanden och ofta finns det ett samband mellan moderns och barnets övervikt och fetma.

    Syfte: Att undersöka vilka faktorer som kan leda till övervikt och fetma hos mödrar och barn med låg socioekonomisk status.

    Metod: Denna studie är en analytisk litteraturstudie med ett systematiskt tillvägagångssätt. Elva vetenskapliga artiklar har granskats och analyserats i syfte att finna möjliga samband mellan mammors och barns fetma.

    Resultat: Det finns flera multifaktoriella orsaker som kan bidra till ohälsa hos föräldrar, framför allt ensamstående mödrar. Inkomst, utbildning, familjeförhållanden, kunskap och känslomässiga aspekter är faktorer som kan ligga bakom övervikt och fetma hos både mamma och barn.

    Slutsats: Slutsatsen av denna litteraturstudie var att övergripande förstå och identifiera faktorer som kan kopplas till övervikt och fetma i familjer med låg socioekonomisk status och därigenom få kunskap om var insatser kan implementeras

    The Role of Primary Visual Cortex in Visual Awareness2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Despite its great complexity, a great deal is known about the organization and information-processing properties of the visual system. However, the neural correlates of visual awareness are not yet understood. By studying patients with blindsight, the primary visual cortex (V1) has attracted a lot of attention recently. Although this brain area appears to be important for visual awareness, its exact role is still a matter of debate. Interactive models propose a direct role for V1 in generating visual awareness through recurrent processing. Hierarchal models instead propose that awareness is generated in later visual areas and that the role of V1 is limited to transmitting the necessary information to these areas. Interactive and hierarchical models make different predictions and the aim of this thesis is to review the evidence from lesions, perceptual suppression, and transcranial magnetic stimulation (TMS), along with data from internally generated visual awareness in dreams, hallucinations and imagery, this in order to see whether current evidence favor one type of model over the other. A review of the evidence suggests that feedback projections to V1 appear to be important in most cases for visual awareness to arise but it can arise even when V1 is absent.

    Användarfall ur ett spårbarhetsperspektiv2000Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    I detta arbete har en undersökning genomförts angående hur spårbarhet upprätthålls vid användning av användarfall. Rapporten behandlar spårbarhet och användarfall separat för att belysa viktiga fakta inom båda områdena. Syftet med arbetet var att ta reda på hur olika tillvägagångssätt för att representera användarfall upprätthöll spårbarhet mellan olika krav, och mellan krav och dess ursprung. Informationen inom problemområdet samlades in genom en litteraturstudie. I undersökningen identifierades flera olika typer av spårbarhet, vilka sedan låg till underlag för identifiering av spårbarhet i användarfall. Undersökningen visade också att det finns flera olika sätt att representera användarfall, i allt från naturligt språk till formella diagram. Resultatet av undersökningen visade även att användningen av ett modelleringsspråk som Unified Modeling Language (UML), med inbyggda relationer och namnkonventioner, gjorde att spårbarhet kunde upprätthållas mellan olika krav, och mellan krav och dess ursprung. En begränsad spåbarhet identifierades i samband med att mindre formella representationer av användarfall använts.

    Wrapping XML-Sources to Support Update Awareness2000Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Data warehousing is a generally accepted method of providing corporate decision support. Today, the majority of information in these warehouses originates from sources within a company, although changes often occur from the outside. Companies need to look outside their enterprises for valuable information, increasing their knowledge of customers, suppliers, competitors etc.

    The largest and most frequently accessed information source today is the Web, which holds more and more useful business information. Today, the Web primarily relies on HTML, making mechanical extraction of information a difficult task. In the near future, XML is expected to replace HTML as the language of the Web, bringing more structure and content focus.

    One problem when considering XML-sources in a data warehouse context is their lack of update awareness capabilities, which restricts eligible data warehouse maintenance policies. In this work, we wrap XML-sources in order to provide update awareness capabilities.

    We have implemented a wrapper prototype that provides update awareness capabilities for autonomous XML-sources, especially change awareness, change activeness, and delta awareness. The prototype wrapper complies with recommendations and working drafts proposed by W3C, thereby being compliant with most off-the-shelf XML tools. In particular, change information produced by the wrapper is based on methods defined by the DOM, implying that any DOM-compliant software, including most off-the-shelf XML processing tools, can be used to incorporate identified changes in a source into an older version of it.

    For the delta awareness capability we have investigated the possibility of using change detection algorithms proposed for semi-structured data. We have identified similarities and differences between XML and semi-structured data, which affect delta awareness for XML-sources. As a result of this effort, we propose an algorithm for change detection in XML-sources. We also propose matching criteria for XML-documents, to which the documents have to conform to be subject to change awareness extension.

    Dehumanization in the brain2019Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Dehumanization is a process whereby people fail to view others as human beings. Instead, the others are perceived as nonhuman animals or objects, unworthy of the same moral treatment. Dehumanization has previously been studied in a variety of different scholarly domains without adhering to a uniform theoretical framework. This literature review contrasts research on fully humanized perception, with research on dehumanized perception, and proposes neural areas which are likely to be involved. Not every aspect of dehumanization can be understood at the neurological level. To understand what factors lead up to, and modulates dehumanization, other perspectives might also be necessary. Dehumanized perception is coupled with reduced activity in the social cognitive brain network, a wide network which encompasses several cortical and subcortical areas. This disengages prosocial abilities and allows for other people to be treated like objects and means to an end. One area of special interest is the medial prefrontal cortex (MPFC). It functions as an integration center in the person perception network and is also active when we make moral judgments, empathize, or take the perspective of someone else. For this reason, the MPFC is sometimes used as an index of dehumanized perception.

    Ett skadat hjärta: En litteraturbaserad studie ur ett patientperspektiv2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Myocardial infarction is one of the leading causes of premature death in Sweden. A myocardial infarction is largely lifestyle-related where habits such as smoking, unhealthy eating habits and low physical activity levels are risk factors. To suffer from a myocardial infarction requires a change in the patient’s invasive lifestyle. The nurse has the task of supporting the patient to a better health, provide person-centered care, identify risks and design an individual plan for recovery. The Aim: of this study was to illuminate patients’ experiences of life after a myocardial infarction. Method: A literature-based study with 10 qualitative articles. Results: After a myocardial infarction there were restraints in everyday life that consisted of physical and mental strains. It was found that mental health problems were the most difficult to control and of which many were unprepared. Receiving support in lifestyle changes, feeling a sense of security and daring to be active again was of significant importance. The results showed that support from close relatives and nurses was important for the patients’ recovery. Conclusion: After the myocardial infarction, patients got to learn how to live a new life. New habits and values needed to be created to achieve a sustainable and healthy life. Support, security, a good strategy and motivation were essential for a successful recovery.

    Do public sector industrial relations challenge the Swedish model?2018In: Labor history, ISSN 0023-656X, E-ISSN 1469-9702, Vol. 59, no 1, p. 87-104Article in journal (Refereed)
    Abstract [en]

    This article discusses recent developments in public sector labour relations in Sweden from a historical, gender and power relations perspective. The main question is whether these trends challenge the established Swedish industrial relations system. Our point of departure - yet chronologically also the point of arrival - is the Swedish Municipal Workers' Union, Kommunal's, exit from the coordinated wage setting model within the Swedish Trade Union Confederation (Landsorganisationen, LO) in 2015/2016. The immediate reason was that Kommunal, representing one-third of the LO members, including many low-paid women, turned down the LO's proposal on a general wage increase for low-wage groups. Instead, Kommunal urged to upgrade wages for a specific member group, the auxiliary nurses. This broke an almost uninterrupted 20-year-long period of labour market cooperation and coordination that was introduced in 1997 through the so-called Industry Agreement (Industriavtalet). This agreement was launched in the wake of the deep financial crisis in the early 1990s, and the neoliberal move towards a complete decentralization of pay negotiations. How should this move by Kommunal be interpreted? Why, and when, has the centralized system become a straitjacket for Kommunal, when for decades it seemingly was a precondition for both private and public union strength?

    Welfare States and the Need for Social Protection of Self-Employed Migrant Workers in the European Union2015In: International Journal of Comparative Labour Law and Industrial Relations, ISSN 0952-617X, E-ISSN 1875-838X, Vol. 31, no 4, p. 391-410Article in journal (Refereed)
    Abstract [en]

    So-called bogus – or false – self-employment has been increasingly highlighted as a problem within the European Union (EU), especially since the first eastern expansion in 2004. Although the concept is not fully clear in legal terms, a common denominator of most definitions is that bogus self-employment can be seen as ‘disguised employment’, occurring when someone who has an employee status in practice is not classified as an employee, in order to hide the actual legal status and to avoid costs such as taxes and social security contributions. In the light of different welfare systems, industrial relations and EU legislation, this article discusses this issue, drawing empirically on findings from a project about precarious employment in twelve EU countries. Although there are some fairly strict definitions of the ‘employee concept’ within the EU, the difficulties of identifying the employer leave the bogus self-employed in a legal limbo. No European Social Model has curtailed this problem, despite an expressed desire to address all aspects of precarious work. However, the inclusion of all ‘self-employed’ workers within social insurance systems and workers with an employee status in practice seems possible also under existing EU regulations. It is rather a matter of goodwill and the resources to scrutinize the terms and conditions of employment.

    Their own stories - how Polish construction workers posted to Sweden experience their job situation, or resistance versus life projects2015In: Transfer - European Review of Labour and Research, ISSN 1024-2589, E-ISSN 1996-7284, Vol. 21, no 1, p. 23-36Article in journal (Refereed)
    Abstract [en]

    This study draws primarily on in-depth interviews with nine male Polish construction workers posted to Sweden in the early 2010s. The emphasis lies on their own experiences of being exposed to what they saw as unjust working conditions, and why they accept them or react against them. The overarching research questions are why Polish workers go to Sweden, and, more importantly, why they stay even when they feel unfairly treated or directly cheated by their employers. The main points of interest are wages, work environment, employment contracts and relations with different labour market players, including the EU. It was very clear that none of the Polish workers had ever heard of the EU Posted Workers Directive. Still, the lack of serious resistance, our study argues, was not because of poor knowledge about their legal rights, but was linked to a wish to fulfil a ‘life project’ back home in Poland, such as building a house, starting a company, being able to afford to start a family and raise children, or saving for retirement. This wish helped the workers to swallow ‘unfair’ treatment.

    Women and Wildcats: Unofficial Women’s Strikes in Sweden in the 1970s and 1980s2015In: Workers of the World: International Journal on Strikes and Social Conflict, ISSN 2182-8938, Vol. 1, no 6, p. 64-83Article in journal (Refereed)
    Abstract [sv]

    While the strike propensity in manufacturing declined in the 1980s and 1990s, it remained high or even increased in services, health care, education and so on. Thegrowing portion of tertiary sector employment has further moved the searchlight from men to women, as the demographic transformation in work has promoted a feminization of strikes. However, what if we go back in history, to when strikes and industrial conflict was still mainly a men’s concern? Did women go on strike at all, and if so, how did their strikes differ from the overall pattern? The 1970s was the decade of “resurgence of class conflict” in Western societies, including Sweden, with an outstanding upsurge of strikes in many countries. There is an affluence of studies of both the 1970s strike-waves and single strikes in this rebellious decade, but few of them deal with female-dominated strikes. This article explores women’s strikes in Sweden in the 1970s and 1980s with special attention to the treatment in the Labour Court, since the article finds a remarkable difference in legal outcome between “male” and “female” strikes.

    MED13 regulates substrate utilization and bioenergetics in human skeletal muscle2018Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The Mediator Complex has an essential function in regulating the transcription of several genes, working as a scaffold between transcription factors and polymerase II. It is composed of 26 subunits, with the kinase, or CDK subunit, being one of the most important for the mediator complex activation. In fact, when the kinase subunit is bound to the complex, binding between the mediator complex and polymerase II is hindered and therefore transcription is repressed. This suggests that the kinase complex and its components are essential for the expression of polymerase II transcripts. MED13 is part of the kinase subunit and high-throughput transcriptomic analysis showed MED13 as being upregulated in human skeletal muscle biopsies following an oral glucose tolerance test.

    The aim of this project is to understand the function of MED13 in human skeletal muscle metabolism and the relationship between MED13 knockdown and AMPK (AMP-activated protein kinase) function. Primary human skeletal muscles cells obtained from three healthy donors were cultured and transfection with MED13 siRNA was performed on differentiated myotubes. Metabolic assays such as fatty acid and glucose oxidation were performed as well as mitochondrial function. Quantitative PCR and western blot techniques were used to assess the pathways altered by MED13.

    Glucose uptake and fatty acid transporters were significantly increased upon MED13 silencing. Reduction in fatty acid oxidation and unchanged glucose oxidation suggest that MED13 favors substrate storage. Western blot analysis hinted on an increase in AMPK phosphorylation and in mitochondrial biogenesis. The production of ATP by mitochondria was also increased.

    An evaluation of algorithms for real-time strategic placement of sensors2004Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    In this work an investigation is performed in whether the algorithms Simultaneous Perturbation Stochastic Approximation (SPSA) and Virtual Force Algorithm (VFA) are suitable for real-time strategic placement of sensors in a dynamic environment. An evaluation of these algorithms is conducted and compared to Simulated Annealing (SA), which has been used before in similar applications.

    For the tests, a computer based model of the sensors and the environment in which they are used, is implemented. The model handles sensors, moving objects, specifications for the area the sensors are supposed to monitor, and all interaction between components within the model.

    It was the belief of the authors that SPSA and VFA are suited for this kind of problem, and that they have advantages over SA in complex scenarios. The results shows this to be true although SA seems to perform better when it comes to smaller number of sensors to be placed

    Hypothesis evaluation in command and control systems2005Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This work focus on situation prediction in data fusion systems.

    A hypothesis evaluation algorithm based on artificial neural networks is introduced. It is evaluated and compared to an algorithm based on Bayesian networks which is commonly used. It is also compared to a simple "dummy" algorithm.

    For the tests, a computer based model of the environment, including protected objects and enemy objects, is implemented. The model handles the navigation of the enemy objects and situational data is extracted from the environment and provided for the hypothesis evaluation algorithms.

    It was the belief of the author that ANNs would be suitable for hypothesis evaluation if a suitable data representation of the environment were used. The representation requirements include pre processing of the situational data to eliminate the need for variable input size to the algorithm. This because ANNs poorly handles this; the whole network have to be retrained each time the amount of input data changes.

    The results show that ANNs performed best of the three and hence seems to be suitable for hypothesis evaluation.

    Skräckens ansikte: en studie i skräckgenrens historia och inflytande för visualiseringen av spelkaraktärer2010Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Hur utformas spelkaraktärer för att förmedla skräck till betraktaren?  Spelkaraktärer inom survival-horrorgenren har flera konventioner baserade på skräckgenrens tidigare historia. Både kvinnliga och manliga karaktärer har tydligt fokus på sexualisering. Kropp och klädsel används för att markera avstånd från betraktarens kultur. Färger som betonar sexualitet, våld och ondska återkommer i karaktärernas utformning. Ljus och klädsel används även för att begränsa betraktarens information om karaktären. 2 karaktärer har producerats, en av vardera kön. Dessa används till en enkätundersökning för att testa relationen mellan vana av skräckgenren, hur skräckinjagande de uppfattas samt hur sexualiserade de anses. Resultaten av undersökningen är att det mest avgörande för att skapa skräckinjagande karaktärer var att de betraktas som fysiskt farliga och att karaktären inte är en del av betraktarens kultur. Relationen mellan skräck och kultur kan vidareutvecklas i framtida arbete inom krigs- och propagandaaffischer relevant. Skräckgenren och propaganda är något som tycks innehålla flera likheter.

    Hållbarhetsredovisning som marknadsföringsverktyg: En studie om varför hållbarhetsredovisningen används eller inte används i företag inom detaljhandelns hållbara marknadsföring för att främja en hållbar konsumtion2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sustainable consumption has emerged from the concept of sustainable development and is essential since the current consumption pattern is not sufficiently sustainable. Sustainable consumption is to consider the environmental, social and economic consequences of consumption in order to satisfy the needs of the present as well as the needs of future generations. The problems which come from the current consumption pattern, has resulted in that sustainable marketing has become a new way of thinking that companies work with to be able to take responsibility for these problems. A tool that can be reliable and which companies can work with to promote sustainable thinking is the sustainability reporting.

     The purpose of the study is to investigate from a company’s perspectivewhy the sustainability reporting is used or not in the sustainable marketing of retail companies to promote a sustainable consumption.In order to achieve the purpose of the study, a qualitative method has been applied. With the qualitative method as a basis, semi-structured interviews have been employedwith respondents active in the retail trade with both knowledge and experience of sustainability reporting and sustainable marketing. The study also investigates the sustainability reports of the interviewed companies.

     The study is based on the theories of sustainable marketing, stakeholder theory and the legitimacy theory. Furthermore, the concepts of sustainable development, sustainable consumption and sustainability reporting also play an important role in enabling answers to the research problem and in order to achieve the purpose of the study. The study's collected data has given indications that companies in the retail sector that use the sustainability reporting in their sustainable marketing do it to achieve the legitimacy of their sustainable work and sustainable alternatives that they believe promote sustainable consumption. The sustainability reporting is therefore used to gain confidence and confirmation of the sustainability work of the companies. But also, to create understanding and raise awareness of the current unsustainable consumption pattern and to gain competitive advantage. It also emerged in the study that most companies in the retail sector do not use the sustainability reporting in their sustainable marketing to promote sustainable consumption. Because they can use other sustainable activities and offer their stakeholders other sustainable alternatives which motivates them to want to promote sustainable consumption and therefore gain legitimacy. The study helps to increase knowledge and understanding to retail companies of why sustainability reporting is used or not in the sustainable marketing of retail companies to promote a sustainable consumption. Proposals for further studies can be to investigate how stakeholders agree that sustainability reporting is used or not in the sustainable marketing of retail companies to promote a sustainable consumption.
