    Sjuksköterskors patientundervisande arbete: Ett otydligt fält2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Aim: The overall aim of this thesis is to explore, describe and critically assess conditions for nurses’ patient education work. This was carried out in two stages. In the first stage, the aim was to describe nurses’ experiences and perceptions of patient education work in relation to organisation, environment, professional cooperation and pedagogical competence, as well as describe differences between primary, municipal and hospital care. In the second stage, the aim was to identify discourses in the ways managers speak of the conditions for nurses’ patient education work in primary and hospital care.

    Methods: In studies I and II, a randomised selection of nurses (842) received a questionnaire of 47 items concerning factual experiences and perceptions patient education, and 13 background items. Questionnaires were returned by 83 % of the participants. The items concerned organisation, environment, professional cooperation (I), and pedagogical competence (II). Descriptive statistics, non-parametric tests and content analysis for open-ended items were used. In studies III and IV, data was collected from three focus group interviews with managers (n=10) in hospital care, and three focus groups interviews with managers (n=10) in primary care. An explorative, qualitative design with a social constructionist perspective was used. The data was analysed with a critical discourse analysis.

    Results: Nurses’ perceptions of conditions for patient education differ between healthcare settings, in favour of primary care (I, II). The nurses in primary care had better conditions and more managerial support, for example in the allocation of uninterrupted time (I). The primary care nurses had an advantage in relation to those in municipal or hospital care when it came to following research in patient education as well as how they perceived their own competences, pedagogical education and post graduate specialisations (II). Due to a heavy workload and a lack of time, the managers in hospital care could neither see the importance of their role as a supporter of the patient education provided by the nurses nor their role in the development of the nurses’ pedagogical competence. The managers used (mainly) organisational, financial, medical and legal discourses for explaining their failure to support the nurses’ providing patient education (III). The discursive practice in primary care comprised a discourse order of economic, medical, organisational and didactic discourses. The economic discourse was the predominant one, to which the organisation had to adjust. The medical discourse was self-evident and unquestioned. The managers initiated reorganisations, generally due to financial constraints. The nurses’ pedagogical competence development was unclear. Practicebased experiences of patient education were considered very important, whereas theoretical pedagogical knowledge was considered less important (IV).

    Conclusions: Nurses’ patient education work must be made visible and be given sufficient resources. In this process, support from their managers is considered vital. Managers’ support for nurses’ practical and theory-based pedagogical competence development needs to be strengthened.

    With or without context: Automatic text categorization using semantic kernels2016Doctoral thesis, monograph (Other academic)
    Abstract [en]

    In this thesis text categorization is investigated in four dimensions of analysis: theoretically as well as empirically, and as a manual as well as a machine-based process. In the first four chapters we look at the theoretical foundation of subject classification of text documents, with a certain focus on classification as a procedure for organizing documents in libraries. A working hypothesis used in the theoretical analysis is that classification of documents is a process that involves translations between statements in different languages, both natural and artificial. We further investigate the close relationships between structures in classification languages and the order relations and topological structures that arise from classification.

    A classification algorithm that gets a special focus in the subsequent chapters is the support vector machine (SVM), which in its original formulation is a binary classifier in linear vector spaces, but has been extended to handle classification problems for which the categories are not linearly separable. To this end the algorithm utilizes a category of functions called kernels, which induce feature spaces by means of high-dimensional and often non-linear maps. For the empirical part of this study we investigate the classification performance of semantic kernels generated by different measures of semantic similarity. One category of such measures is based on the latent semantic analysis and the random indexing methods, which generates term vectors by using co-occurrence data from text collections. Another semantic measure used in this study is pointwise mutual information. In addition to the empirical study of semantic kernels we also investigate the performance of a term weighting scheme called divergence from randomness, that has hitherto received little attention within the area of automatic text categorization.

    The result of the empirical part of this study shows that the semantic kernels generally outperform the “standard” (non-semantic) linear kernel, especially for small training sets. A conclusion that can be drawn with respect to the investigated datasets is therefore that semantic information in the kernel in general improves its classification performance, and that the difference between the standard kernel and the semantic kernels is particularly large for small training sets. Another clear trend in the result is that the divergence from randomness weighting scheme yields a classification performance surpassing that of the common tf-idf weighting scheme.

    Vårdande och lärande sammanflätas i genuina möten: erfarenheter, förutsättningar och ansvarpå utbildningsvårdavdelning2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Aim: The overall aim of this thesis is to create knowledge about caring and learning asan intertwining phenomenon at a Dedicated Education Unit and how it can bedeveloped.

    Approach and methodA lifeworld approach, based on the phenomenological philosophies foremost derivedfrom Husserl and Merleau-Ponty was used and carried out in lifeworld interviews andwith meaning-oriented analysis in accordance with reflective lifeworld research. Theparticipants were: 13 student nurses (study I), 11 patients (study II), 8 supervisors (studyIII) all from the same DEU in orthopedic care and 10 managers from various DEUs(study IV).

    Main findingsIntertwined caring and learning is most evident in genuine encounters between studentsand patients, supported by supervisors and managers. The intertwining is created inappealing challenges where students feel safe and ready. In the encounter with thepatient they gain a sense of the whole where they can find their personal style. Patients,who feel invited to participate, could describe the encounter with students as genuineand a new dimension in nursing care. These encounters are characterized by closeness,thoroughness, accessibility, acknowledgement and sensitivity. When the encounter isless genuine, supervisors constitute an essential support for stabilizing the care.Supervisors constantly move in order to either stay close to or stand back, adjusting tothe students’ and patients’ needs. Their demanding task as reflective supervisors requirespauses in order to maintain motivation. The managers’ daily struggle in a stressful andchallenging reality is influenced by them either having or taking responsibility.Differences in approaches are shown in terms of more or less involvement andcommitment in caring environment and educational issues.

    ConclusionsGenuine encounters are characterized by the core of both caring and learning and willthereby benefit both the students and the patients. Identifying and supporting genuineencounters is necessary for students, supervisors and managers. It is time to find ways todevelop a unified view of how caring and learning can be intertwined.

    Body acts queer: Clothing as a performative challenge to heteronormativity2016Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This artistic, practice-based thesis has been developed based on the idea that design creates social and ideological change. From this perspective, Body Acts Queer — Clothing as a performative challenge to heteronormativity introduces an artistic way of working with and exploring the performative and ideological functions of clothing with regard to gender, feminism, and queer. The thesis presents this program for experimental fashion design—exemplified through a series of artistic projects—while also discussing the foundations of such an approach and the different perspectives that have affected the program and its artistic examples. Working with clothing and fashion design through artistic projects using text and bodies, this thesis transforms queer and feminist theory into a creative process and, by looking into bodily experiences of clothing, Body Acts Queer investigates its performative and ideological functions, with a focus on cultural, social, and heteronormative structures. Body Acts Queer suggests a change in the ways in which bodies act, are perceived, and are produced within the fashion field, giving examples of—and alternatives to—how queer design practice can be performed. In this thesis, queer design is explored as an inclusive term, containing ideas about clothing and language, the meeting point between fiction and reality, and the ability to perform interpretation and bodily transformations—where pleasure, bodily experiences, and interaction create a change.

    Following Tweets Around: Informetric methodology for the Twittersphere2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The purpose of this thesis is to critically discuss methods to collect and analyse data related to the interaction and content on the social platform Twitter. The thesis contains examples of how networked communication can be studied on Twitter, based on the affordances of the platform considering interaction with interfaces and other users. The foundational problem is that social science Twitter research has been based on easily accessible data without introducing or discussing criteria for collecting appropriate samples for a given research task.The thesis builds on one literature review and four studies of political Twitter communication. The analyses are based on a view of the Twitter platform as a non-neutral filtering gatekeeper. On the one hand, Twitter treats content and users asymmetrically, by emphasising the popular. On the other hand, Twitter determines what data are available and how data can be accessed through the API (application programming interface). How Twitter provides access to the data in turn affects the analyses the researcher does. The central problem of the thesis is that researchers do not know what relevant data are not collected. Data collection based on keywords, hashtags or users creates data sets that contain fragments of conversations. To solve the problem, a new method was developed. By combining the hashtag and user-based methods, replies to collected tweets were stored, regardless if they contained a tracked hashtag or not.The four studies this thesis builds on show a complexity of collecting and analysing Twitter data. A key finding is that conversations beyond the hashtag can be quite extensive. As a consequence of this, communication networks based on hashtagged replies were found to be potentially very different from networks based on replies from a more complete data set, where non-hashtagged replies are also included. A network based on hashtagged communication is thus misleading compared to a complete communication network.Apart from that it is not entirely trivial to identify the parameters to define what should be studied; tests of the API showed that complete data sets cannot be obtained. Therefore, it is important to reflect on both the data collected and the data excluded, not only as a result of the sampling criteria but also what is not given access to. It is also important to be clear about the affordances for interaction that exist when the study is made, both in the user interface but also what API allows and permits.This research contributes with knowledge about how Twitter is used in the context being studied, but the main contribution is methodological. With the method developed, collection of more complete data sets is enabled, as is analysis of the conversations that take place on the platform. This results in more accurate measurements of the activity. Based on the results of this thesis, there are reasons to suspect that previous studies could differ in terms of results such as communication network size and shape, as well as the type of users that emerges as prominent in the material, compared to if replies that do not contain the studied hashtag had been collected.

    Dressing wearing: Movement directed by dress - dress directed by movement2016Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Contemporary dance and modern ballet often focus on conveying emotions through patterns of movement which may be abstract, obvious, or anywhere in between, supported by music, sound, or spoken words that set the mood. Scenography is typically sparse or confined to the available space, leaving the dancers as the main instrument of communication. This work explores dressing and wearing, with a focus on how garments can inform and direct movement, choreography, and performance, and in turn how movement may inform and contribute to the development of dynamic garments. Through a series of live experiments, ranging from self-instigated performance/video work in collaboration with choreographers and dancers to performances of garment interaction associated with everyday life dressing, the performative, spatial, and interactive properties of garments are explored. The results present alternative models of collaborative interaction related to various aspects of kinaesthetics, choreography, scenography, and performance space, and offer wide-ranging creative potential. The work shows how designers and choreographers can collaborate on performance scenarios within the context of modern ballet and contemporary dance productions, thus creating conceptual garments that influence the design, choreography, and movement pattern based on a re-conception of what it means to dress and to wear. In relation to the act of dressing and undressing, alternative types of garment and ways of wearing and performing were found where garments act as co-choreographers in the development of performances. Moreover, by having wearing and dressing as a form of choreography these acts, act as the co-creator of garments both in our everday lives and on stage. As a consequence, the results also demonstrates how the agency of garments can function as a manuscript in modern dance, and how performance itself redefines the notion of wearing and the concept of garments.

    Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels: Experimental and Modeling Approach2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified. Among the available thermal conversion technologies, combustion in grate-fired furnaces is by far the most common mode of fuel conversion. In recent years, Fluidized-Bed (FB) technologies have grown to become one of the most suitable technologies for combustion and gasification of biomass and waste-derived fuels.In spite of the benefits, however, some difficulties are attributed to the thermal conversion of the alternative fuels. Ash-related issues could be a potential problem, as low-grade fuels may include considerable concentrations of ash-forming elements such as K, Na, S, Ca, Mg, P, Si and Cl. These elements undergo many undesirable chemical and physical transformations during the thermal conversion, and often cause operational problems such as deposition-related issues, slag formation in furnaces, corrosion of the heat transfer surfaces, and bed agglomeration of the fluidized-beds. Ash-related problems in the utility boilers are a major concern that may result in decreased efficiency, unscheduled outages, equipment failures, increased cleaning and high maintenance costs.This thesis investigated the ash behavior and ash-related problems in two different FB conversion systems: a Bubbling Fluidized-Bed (BFB) boiler combusting solid waste, and a Dual Fluidized-Bed (DFB) gasifier using biomass as feedstock. Full-scale measurements, chemical analysis of fuel and ash, as well as thermodynamic equilibrium modeling have been carried out for the BFB boiler (Papers I-IV), to investigate the impact of reduced-bed temperature (RBT) and also co-combustion of animal waste (AW) on the ash transformation behavior and the extent of ash-related issues in the boiler. For the DFB gasifier (Paper V), a thermodynamic equilibrium model was developed to assess the risk of bed agglomeration when forest residues are used as feedstock.The experimental results showed that the RBT and AW co-combustion could decrease or even resolve the ash-related issues in the BFB boiler, resulting in a lower deposit-growth rate in the superheater region, eliminating agglomerates, and a less corrosive deposit (in RBT case). Thermodynamic equilibrium modeling of the BFB boiler gave a better understanding of the ash transformation behavior, and also proved to be a reliable tool for predicting the risk of bed agglomeration and fouling. The modeling of the DFB gasifier indicated a low risk of bed agglomeration using the forest residues as feedstock and olivine as bed material, which was in good agreement following the observations in a full-scale DFB gasifier.

    Investigating the Reaction Kinetics of Tropical Wood Biomass: A Prospect for Energy Recovery2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The utilization of wood biomass for energy recovery purposes is a phenomenon that is increasingly attracting attentions from researchers, companies and countries all over the world. The effect of climate change as largely represented by global warming leading to glacier ice melting and an unprecedented rise in sea level is a worrisome development. One of the causal agents of this scenario is the increase in world’s greenhouse gas emission. A sure method of approach to ending the problem is to drastically reduce the emission level to the barest minimum, or to zero level if possible. Wood biomass conversion via thermal treatment is an activity capable of reducing the emission possibility as the CO2 released during the conversion is effectively taken care of. Another benefit derivable from the conversion is taking care of what otherwise would have been termed a waste and treated as such. The envisaged use of wood resource to solve the lingering power problem in Nigeria is an effort in the right direction.

    The thesis highlights the conversion processes, as well as the reaction kinetics involved. Reaction parameters such as temperature, heating rate, partial pressure, and flow rate were investigated for the purpose of identifying their effect on the conversion processes. The typical kinetic parameters obtained during the conversion processes would be of high importance in the design and configuration of reactors meant for the optimum conversion of wood waste biomass as a valuable resource. With the non-tropical wood biomass already deployed for energy conversion in the developed countries, the similarity in the trend as regards conversion reactions (char formation and

    conversions, kinetic parameters) compared to the tropical counterpart is a welcome development. This suggests the candidacy of non-tropical wood biomass for energy recovery purposes as a viable one.
