    Vårdares upplevelser av att arbeta med döden och döendet utifrån hospicefilosofin: En intervjustudie2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Death is considered a stressor to all health care personnel and previous research shows that this applies to hospice caregivers as well. In addition, a number of common coping strategies are impossible to use due to the specific environment. One study however points out low burn-out rating among the hospice caregivers and suggests the holistic nursing perspective, among others, as one of the possible reasons for this seemingly ambivalent finding. Can the hospice philosophy influence the view on death among hospice caregivers? An interview based study was conducted among caregivers working in a hospice in Sweden, where three participants took part. The manifest content relating to the purpose of the study was identified and analyzed using qualitative content analysis. The result shows that hospice caregivers indeed are influenced by the hospice philosophy in areas such as the view on end-of-life care, dying and professional cooperation. The participants displayed affection for their work style and a variety of ways in which to cope with the difficulty of their work. Work based on a philosophy that permeates the care of the patients seems to increase the appreciation of each other as co-workers. Further research in this area can be of interest.

    Ett holistiskt Business Intelligence för användning i Verksamhetsutveckling2015Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Världen förändras. Alla kan kommunicera med alla och kunskap är lättillgänglig. Idag kan vi skicka data mellan varandra med mobiltelefoner utan några direkta geografiska begränsningar och med hastigheter i nivå med vad en vanlig dator gjorde internt mellan processorn och internminnet 1984. Informations- och kommunikations-teknologin har skapat nya förutsättningar för företag att göra affärer samtidigt som den behövs för överlevnad med dagens snabba samhälleliga förändringar.

    Personalen beskrivs ofta som företagets viktigaste tillgång. Verksamhetens prestation beror mycket på deras engagemang och möjligheter att utföra sina arbetsuppgifter. Samtidigt är det även de som kan sina egna arbetsuppgifter bäst och har mycket kunskap kring hur de kan förbättras. Däremot är det inte så lätt att få fram dessa kunskaper, och som en f.d. koncernchef för Siemens sagt om problematiken: ”Om Siemens visste allt det som Siemens vet skulle vi inte ha några problem”.

    Den här studien ska utreda hur mobila teknologier kan användas för att ta till vara på personalens inneboende kunskaper på ett systematiskt sätt för att användas med Business Intelligence. Detta för att skapa möjligheter till anpassningsbara och lärande organisationer samt ge förutsättningar för innovativa organisationsstrukturer och affärsmodeller.

    De slutsatser som dras är att om bara företaget förstår relevansen i att anpassa sig, värdet i personalens inneboende kunskaper samt att de är beredda att ta initiativet, finns det stora möjligheter till att skaffa sig insikter kring sin egen verksamhet vilka kan användas för ständiga förbättringar.

    Kartläggning av faktorer som påverkar acceptansen vid införande av telemedicin i ett utvecklingsland: IT som stöd för att bedriva vård över stora avstånd2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Allt fler organisationer väljer att förbättra sin verksamhet med hjälp av ett informationssystem. Användningen av datoriserade informationssystem ökar inom hälso- och sjukvården och sjuksköterskorna blir alltmer beroende av IT. Idag utgör telemedicinska tillämpningar en delmängd av alla de IT-tillämpningar som finns inom hälso- och sjukvården. Införandet av telemedicin bär med sig stora problem och hinder och ett av de mest kritiska problemen som bör försöka undvikas är utebliven användaracceptans. Då tidigare undersökningar inom telemedicin främst har genomförts i industriländer syftar detta arbete till att undersöka vilka faktorer som kan påverka acceptansen vid införande av telemedicin i utvecklingsländer. Genom att intervjua och observera sjuksköterskor och en systemutvecklare verksamma i ett telemedicinprojekt i Indien erhölls faktorer som har både en positivt och negativ inverkan på användaracceptansen vid införande av telemedicin. Faktorerna som framkom i resultatet var information och utbildning, upplevelsen av ny teknik, tidigare erfarenheter av datorer, inledande svårigheter vid användning av systemet, förståelsen för nyttan med systemet, användarmedverkan, användbarhet, begränsningar vid arbete med systemet, arbetsbelastning, mentala hinder, rädsla för att mista den yrkesverksamma friheten, förändringsovilja, fast i en gammal föreställning och teknikhinder.

    Obligatoriskt krav på hållbarhetsredovisning: Faktorer till utmaningar som kan uppstå i företags praktiska arbete2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Annual Account Act (1995:1554) introduced a change (2016:947) which implies that larger Swedish companies are forced to establish a sustainability report. In a previous survey it appears that nine out of ten companies experience the new legal requirement as challenging. This study therefore contributes with knowledge of which these challenges could be and what they may depend on. The purpose of the study is to observe what factors that are the reasons why companies perceive implementation of law (2016:947) as challenging. By this, the study can contribute to understand the practical work in the preparation of sustainability reports. It can be useful for companies that switch from voluntary to statutory sustainability reporting or companies that establish a sustainability report for the first time in a connection with a legal requirement.

    To achieve the aim, the study has been based on a qualitative research method in the form of interviews. There have been eight interviews with sustainability managers in companies within the fashion industry as well as the sports-and leisure industry. In order to gain empirical knowledge about the practical work, a qualitative method was considered most appropriate because it was desired that the informants provided practical examples. The result of the study can be explained by using the implementation theory where the properties understand, can and will are presented. In order to pay attention to difficulties with implementation, the study will investigate whether the companies process these three properties. When implementing a decision, it is essential to know what properties companies have in order to understand the effects of the control. In implementation theory, it appears that it is most problematic if there is no willingness to implement. The result from the study shows that there is challenges within the companies that can be linked to the properties understandand can. The property will appear in this study unable to connect to the challenges in the companies.

    Effects of Aloe barbadensis Mill. extract (AVH200®) on human blood T cell activity in vitro2016In: Journal of Ethnopharmacology, ISSN 0378-8741, E-ISSN 1872-7573, Vol. 179, p. 301-309Article in journal (Refereed)
    Abstract [en]

    ETHNOPHARMACOLOGICAL RELEVANCE: Aloe barbadensis Mill. (Aloe vera) is a widely used medicinal plant well reputed for its diverse therapeutic applications. It has been used for thousands of years in folk medicine to treat various conditions and the Aloe vera gel has been reported to possess anti-inflammatory as well as immunostimulatory and immunomodulatory properties. However, the mode of action is still unclear.

    AIM OF THE STUDY: The aim of this study was determine the effects of two well-defined A. barbadensis Mill. extracts AVH200® and AVE200 on human blood T cells in vitro.

    MATERIALS AND METHODS: Peripheral blood mononuclear cells (PBMC) from healthy donors were stimulated polyclonally in the presence or absence of AVH200® and AVE200. The T cell phenotype was investigated by flow cytometry, cell proliferation was determined by CFSE dye and thymidine assay, respectively and cytokine secretion was determined by MSD® Multi-Spot Assay system and ELISA.

    RESULTS: The presence of AVH200® resulted in a reduced expression of CD25 among CD3(+) T cells and suppression of T cell proliferation in a dose dependent manner. Furthermore, AVH200® reduced the expression of CD28 on CD3(+) T cells. AVH200® also reduced the secretion of IL-2, IFN-γ and IL-17A in PBMC cultures. The AVH200® dose dependent reduction in T cell activation and proliferation recorded in the cell cultures was not due to apoptosis or cell death. Additionally, AVH200® was found to be more effective as compared to AVE200 in reducing T cell activation and proliferation.

    CONCLUSION: AVH200® has the potential to reduce the activation, proliferation and cytokine secretion of healthy human blood T cells. Our study suggests that AVH200® has a suppressive effect on human blood T cells in vitro.

    ARAVQ som datareducerare för en klassificeringsuppgift inom datautvinning2004Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    Adaptive Resource Allocating Vector Quantizer (ARAVQ) är en teknik för datareducering för mobila robotar. Tekniken har visats framgångsrik i enkla miljöer och det har spekulerats i att den kan fungera som ett generellt datautvinningsverktyg för tidsserier. I rapporten presenteras experiment där ARAVQ används som datareducerare på en artificiell respektive en fysiologisk datamängd inom en datautvinningskontext. Dessa datamängder skiljer sig från tidigare robotikmiljöer i och med att de beskriver objekt med diffusa eller överlappande gränser i indatarymden. Varje datamängd klassificeras efter datareduceringen med hjälp av artificiella neuronnät. Resultatet från experimenten tyder på att klassificering med ARAVQ som datareducerare uppnår ett betydligt lägre resultat än om ARAVQ inte används som datareducerare. Detta antas delvis bero på den låga generaliserbarheten hos de lösningar som skapas av ARAVQ. I diskussionen föreslås att ARAVQ skall kompletteras med en funktion för grannskap, motsvarande den som finns i Self-Organizing Map. Med ett grannskap behålls relationerna mellan de kluster som ARAVQ skapar, vilket antas minska följderna av att en beskrivning hamnar i ett grannkluster

    En situerad ansats för utvecklingen av en räknande robot2003Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Den situerade ansatsen inom artificiell intelligens har i tidigare experiment visat på stora möjligheter vid utvecklingen av enkla beteenden. Ansatsens framgångar är dock inte lika tydliga när det kommer till utvecklingen av mer komplexa beteenden som i högre grad påminner om de experiment som gjorts inom traditionell artificiell intelligens. I studien utvecklas en agent med ett ”Extended Sequential Cascaded Network” som kontrollarkitektur för att lösa en uppgift som kräver ett ”räkneliknande beteende”. Utvecklingen av nätverket grundas på en situerad syn på kognition, däribland att designern i så liten grad som möjligt skall styra utvecklingen. Experimentets resultat visar på en agent som inte ens löser den enklaste versionen av uppgiften. I diskussionen härleds misslyckandet till svårigheterna med en designeroberoende utveckling.

    Clinical characteristics of asymptomatic left ventricular diastolic dysfunction and its association with self-rated health and N-terminal B-type natriuretic peptide: a cross-sectional study2016In: ESC Heart Failure, E-ISSN 2055-5822, Vol. 3, no 3, p. 205-211Article in journal (Refereed)
    Abstract [en]

    AimsLeft ventricular hypertrophy, obesity, hypertension, and N-terminal B-type natriuretic peptide (Nt-proBNP) predict left ventricular diastolic dysfunction with preserved systolic function (DD-PSF). Self-rated health (SRH) is shown to be associated with chronic diseases, but the association of SRH with DD-PSF is unclear. In light of the clinical implications of DD-PSF, the following goals are of considerable importance: (1) to determine the role of SRH in patients with DD-PSF in the general population and (2) to study the association between Nt-proBNP and DD-PSF.

    Methods and resultsThe current study is a cross-sectional study conducted on a random sampling of a rural population. Individuals 30–75 years of age were consecutively subjected to conventional echocardiography and tissue velocity imaging. Data were collected on 500 (48%) men and 538 (52%) women (n = 1038). DD-PSF was the main outcome, and SRH and Nt-proBNP were the primary indicators. Diabetes mellitus, hypertension, and obesity were accounted for as major confounders of the association with SRH. DD-PSF was identified in 137 individuals, namely, 79 men (15.8%) and 58 women (10.8%). In a multivariate regression model, SRH (OR 2.95; 95% CI 1.02–8.57) and Nt-proBNP (quartile 4 vs. quartile 1 OR 4.23; 95% CI 1.74–10.26) were both independently associated with DD-PSF.

    ConclusionsSRH, evaluated based on a descriptive question on general health, should be included in the diagnostic process of DD-PSF. In agreement with previous studies, our study confirms that Nt-proBNP is a major indicator of DD-PSF.

    Analys och simulering av produktionsflödet på ett tillverkningsföretag: Simulering kombinerat med Lean-principer2018Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Production concurrence within manufacturing companies is continuously increasing due to production requirements and demand of mass produced customized goods. In order to meet customers’ requirements nowadays, companies need to increase customize production without suffering a loss of quality. In pursuance of an increased production on the main shop floor of the industrial partner involved in this project, the company investigates the idea of investing in an automated pressing machine to centralize the process outside different assembly lines. With the help of automation, simulation, and Lean, the potential of the company to reduce lead times to satisfy the customer needs can be increased.

    The aim of this final year project is to investigate the potential of a stator pressing machine to manage the supply of product parts to four assembly lines. One of the requirements is that the yearly volume of the new system could be increased by 50%.

    The methodology used in this study is based on Lean, simulation, and optimization. In order to have an overview of the problem, a situation analysis was made on the current production flow. Therefore, a data collection process was performed through observations, continuous communication with matter experts, and historical data. This data was used to analyze the system and feed the simulation model of the proposed new system. Different Lean tools were also used for the analysis and improvement of the system.

    The company presented ideas on how they wanted the production flow to look like, which were then further developed and used as a basis for the improvement suggestions. One requirement was that the solution had to be Lean inspired.

    The aim of the study was achieved by creating a simulation model to test how the system would behave in different configurations. A first scenario designed as a Pull flow system where the products were only produced according to demand. The second scenario was a Push based system without considering just-in-time production. The first scenario was presented as suggestion for final solution.

    The result from the simulation scenarios showed a clear difference between the two systems. The Pull flow was more suitable due to a drastic decrease in both number of products as work- in-progress and lead time. The final solution, using a Kanban method, and a suggestion for the production layout of the future production flow is presented in the report.

    A review on natural sweetener plant - Stevia having medical and commercial importance2011In: Agronomy Journal, ISSN 0002-1954, Vol. 73, no 1-2, p. 75-91Article, review/survey (Refereed)
    Abstract [en]

    Stevia is a perennial herb that belongs to the Asteraceae family. It is a natural sweetener plant and estimated to be 300 times sweeter than cane sugar. The leaves of stevia are the source of diterpene glycosides, viz. stevioside and rebaudioside. Stevioside is regenerated as a valuable natural sweetening agent because of its relatively good taste and chemical stability. Now it is being cultivated in Japan, Taiwan, Philippines, Hawaii, Malaysia and overall South America for food and pharmaceutical products. Products can be added to tea and coffee, cooked or baked goods, processed foods and beverages, fruit juices,

    Establishment of an Indirect Genetic Transformation Method for Arabidopsis thaliana ecotype Bangladesh2011In: Journal of Central European Agriculture, ISSN 1332-9049, E-ISSN 1332-9049, Vol. 12, no 3, p. 519-528Article in journal (Refereed)
    Abstract [en]

    Arabidopsis thaliana is a small flowering plant belonging to the Brassicaceae family, which is adopted as a model plant for genetic research. Agrobacterium tumifaciensmediated transformation method for A. thaliana ecotype Bangladesh was established. Leaf discs of A. thaliana were incubated with A. tumefaciens strain LBA4404 containing chimeric nos. nptII. nos and intron-GUS genes. Following inoculation and co-cultivation, leaf discs were cultured on selection medium containing 50 mg/l kanamycin + 50 mg/l cefotaxime + 1.5 mg/l NAA and kanamycin resistant shoots were induced from the leaf discs after two weeks. Shoot regeneration was achieved after transferring the tissues onto fresh medium of the same combination. Finally, the shoots were rooted on MS medium containing 50 mg/l kanamycin. Incorporation and expression of the transgenes were confirmed by PCR analysis. Using this protocol, transgenic A. thaliana plants can be obtained and indicates that genomic transformation in higher plants is possible through insertion of desired gene. Although Agrobacterium mediated genetic transformation is established for A. thaliana, this study was the conducted to transform A. thaliana ecotype Bangladesh.

    Dynamiska metoder för små systemutvecklingsprojekt2003Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Litteratur inom systemutvecklingsområdet visar behov av nya snabbare systemutvecklingsmetoder. Orsaken är komplexiteten både i systemutvecklingsprojekten och i organisationer, där systemutveckling sker. Nu föredras små projekt, som omfattar färre än tio deltagare och genomförs på mindre än ett år. De traditionella systemutvecklingsmetoder anses vara lämpliga för stora projekt. Det finns nya systemutvecklingsmetoder, som får benämningen dynamiska metoder, för små projekt. I detta examensarbete studeras faktorer för två dynamiska metoder som gör dem lämpliga för små projekt. De två dynamiska metoderna som kommer att studeras är Extreme Programming och en specifik dokumenterad anpassning av RUP.

    Syftet med detta examensarbete är att studera metoddokumentationen för två dynamiska metoder för att reda ut i vilken utsträckning de passar för små projekt. Ett ytterligare syfte är att genom analys av andras erfarenheter om tillämpningar av de två metoderna redogöra för det som styrker argumenten om deras lämplighet för små projekt.

    För att besvara frågeställningen studerades litteratur och ett antal artiklar. Två telefonintervjuer genomfördes också för att besvara en av de två delfrågorna, som tillsammans utgör frågeställningen för denna studie. Resultatet visar att den specifikt dokumenterade anpassade RUP inte följer alla aspekter för små projekt. Däremot följer Extreme Programming alla de aspekterna.

    Modellering och emulering av en människa- robot samarbetande arbetscell2019Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Collaborative robots are a key challenge in industrial development. The problem today is that industrial robots are not adapted for close collaboration with humans and security gates are a need. This study focuses on developing an emulation model that can demonstrate such collaboration without the need for security gates. The project is based on the concept (virtual commissioning) which is about using emulation tools to develop a digital twin that is a copy of a physical system. With the help of the model, the system's functions and program code will be tested and validated before a real implementation is performed. On behalf of the University of Skövde, the thesis work was carried out to investigate the possibility of a close collaboration between a person and industrial robot in a virtual environment. In the study, two different methods have been developed to investigate the possibility of a collaboration but also to develop an emulation model. With this, operating lists have been created to clarify the person and the robot work tasks. Process scenarios were then created to demonstrate how such collaboration can take place in a virtual environment. A functioning emulation model in which man and robot collaborate, was delivered to the University of Skövde. By using the emulation model, the university can create and test different solutions before an implementation of a real system takes place. Finally, an emulation method is proposed that can be used to develop a digital twin.

    The impact of social media on knowledge management2016In: IFKAD 2016 - 11th International Forum on Knowledge Asset Dynamics: Towards a New Architecture of Knowledge: Big Data, Culture and Creativity Proceedings / [ed] J. C. Spender, Giovanni Schiuma, Joerg Rainer Noennig, Institute of Knowledge Asset Management (IKAM) , 2016Conference paper (Refereed)
    Abstract [en]

    The aim of this paper is to review extant research on the impact of social media on knowledge management (KM) to establish the current body of knowledge and, on this basis, to suggest some promising avenues for future research.

    The study consists of a systematic literature review of eighteen refereed empirical articles on social media and knowledge management. In order to get access to the articles, we used different scientific databases such as Scopus and ProQuest. As keywords, we decided to use multiple keyword combinations. After having read the abstracts of the articles identified, we ended up with a final set of eighteen articles, which represented the basis for analysis. The systematic approach helped us to make sure that the majority of relevant papers would be covered. 

    To the best of the authors’ knowledge, no systematic literature review on social media and knowledge management has previously been published or presented.

    The topic seems to be a promising field for systematic and intensive research and offers a variety of future research avenues.

    Knowledge Waste & Knowledge Loss: What is it All About?2016In: Navus Revista de Gestão e Tecnologia, ISSN 2237-4558, Vol. 6, no 4, p. 38-57Article in journal (Refereed)
    Abstract [en]

    In this paper we are interested in developing an understanding of the concepts of knowledge waste and knowledge loss. The latter can in the worst case lead to "a decreased capacity for effective action or decision making in a specific organizational context" (DeLong, 2004, p. 21). Whereas knowledge waste means that companies are not using the full capacity of existing knowledge. As outlined by Ferenhof (2011) it is any failure in the process of knowledge conversion. These definitions imply differences between the concepts, the literature however suggests that many authors uses them interchangeably. Is that correct? Are the concepts important, of relevance? The present article's aim is to highlight the importance of having better insights into the concepts. The authors believe that both theory and corporate practice will benefit from an improved understanding.

    Knowledge waste in organizations: A review of previous studies2015In: Brazilian Journal of Operations & Production Management, ISSN 1679-8171, Vol. 12, no 1, p. 160-178Article in journal (Refereed)
    Abstract [en]

    In this paper, we are interested in the knowledge that is “wasted” in organizations, that is existing relevant knowledge that is overlooked in the process of knowledge conversion. Given the competitive pressure firms are facing in today´s business environment, a waste of knowledge is not only costly but also dangerous. This means that we consider knowledge from a knowledge at risk perspective. Having this in mind, the purpose of this paper is to review research on knowledge waste in organizations to establish our current body of knowledge regarding this topic. The study consists of a systematic review of 51 peer-reviewed articles addressing knowledge waste in organizations. To the best of the authors’ knowledge, no systematic literature review on this topic has previously been published or presented. The topic seems to be a promising field for intensive research and offers a variety of future research avenues. In view of practitioners, the study´s finding may enable an increased awareness towards the areas where existing knowledge is at the mercy of “waste”. This can assist practitioners to better cope with risks related to this waste and, therefore, better exploit the (limited) knowledge base available.

    Intellectual capital dimensions: state of the art in 20142015In: Journal of Intellectual Capital, ISSN 1469-1930, E-ISSN 1758-7468, Vol. 16, no 1, p. 58-100Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to review extant literature to identify models intended to measure/classify intellectual capital (IC) to establish the current body of knowledge that has been built since the review by Marr et al. (2004).

    Design/methodology/approach – The study consists of a systematic review of peer-reviewed articles on IC classification. The review was conducted for the period 2004-2014 in order to reach the aim. To ensure that all major models are included, important works developed prior to 2004 were captured as well.

    Findings – The review resulted in 83 additional models indicating continued research activities with regard to the topic. These models were merged with prior IC models and mapped on a timeline. The timeline clarifies that 2008, 2010, 2011, 2012 and 2013 represent the years of greatest research activity (outcomes). Additionally, the analysis of the list of IC frameworks resulted in the development of an IC Meta model. It synthesizes research activities in the field and highlights the main IC dimensions and sub-dimensions.

    Research limitations/implications – This study may not have enabled a complete coverage of all existing peer-reviewed articles in the field of IC classification. Yet, it seems reasonable to assume that the review process covered a large proportion of studies available.

    Originality/value – By aggregating and consolidating the IC frameworks covered, the study does not only provide an IC Meta model, but also promising directions for future research.

    Utilization of information and communication technology and educational games in senior secondary schools in Owerri, Imo state Nigeria: Challenges and prospects2016Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Use of information and communication technology in formal education settings is a fundamental issue in management of education across the globe. But in Africa the issues takes a different turn as it regards to how to apply and utilize technology in education. Facility and technology experts have been on debate across board as the literature implies. Thus, understanding the digital native factors behind individuals’ application and utilization is central to the development of ICT in Nigeria and Africa in general. The main goal of this thesis was to explore factors influencing effective utilization of computer and ICT (Computer laboratories) in the secondary school level. However, in the literature the thesis identify issues affecting utilization of computer and ICT facilities in Sub-Sahara Africa (SSA), Nigeria and secondary schools (SS). The thesis proposed the use of educational games to drive the concept of utilization of computer and ICT facilities in the educational sector. In addition to the main goal of the thesis, use of computer and ICT facilities in secondary schools are explored alongside teachers and students interest in educational games. Qualitative interviews and a questionnaire survey were used in conduct of the study. Thematic and descriptive analysis was used to analyze the qualitative and quantitative data respectively.

    The results indicate that computer and ICT facilities (Computer laboratories) were poorly utilized by teachers and students due to lack of funds, poor infrastructure and technology knowledge. The results also demonstrate that teachers and students have knowledge about educational games and are willing to apply it in teaching and learning. But the issues of application of educational games into the mainstream could be hindered by Government curriculum policy and infrastructural facilities. The study indicates the relevance of applying educational games in secondary schools to reduce the level of digital divide among graduates. This thesis further argues that the inclusion of educational games would encourage teachers and students to effectively utilization of computer and ICT Facilities (Computer laboratory).

    ”Såna är dom!”: En socialpsykologisk studie om skillnader mellan unga killars och tjejers stereotypa tänkande och fördomar.2009Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The way man divides his thoughts and sorts them into different boxes, is a cognitive activity which works alike for every person. We split peoplesexterior attributes and characteristic qualities into stereotypes or prejudicemind patterns and treat them along those.

    This study examines through a qualitative method what twelve respondents (six women and six men) between the ages 16-21, think about “intense” conceptions, which may show stereotype or prejudice ways of thinking. There spondents have been chosen regardless ethnic or economic background andare all enrolled in an upper secondary school located centrally in a Swedish big city.

    The purpose is to find out if there are any differences between how some young men and some young women spontaneously think in stereotypical orprejudice patterns. The result is interpreted on the basis of the social cognitive perspective and from out of theories about how people create schemes andprototypes to separate individuals and groups from each other.

    This study suggests that men more easily express their stereotypes and prejudice, while women more often seem to be careful with their stereotypes and prejudice, and end up redefining them. Further in the discussion, aspects involving how the society, if not becoming aware of stereotypes and prejudice, can affect the people representing those stereotypes.

    Fermale immigrant' health and working conditions in Sweden2007In: International Journal of Diversity in Organisations, Communities and Nations, ISSN 1447-9532, E-ISSN 1447-9583, Vol. 7, no 2, p. 275-286Article in journal (Refereed)
    Abstract [en]

    Sweden is one of the European countries that has successively changed from a mainly ethnically homogeneous society into a multi-ethnic society. In 2001, almost 20 per cent of the Swedish population was classified as immigrants, i.e., they were either born abroad and naturalized, of foreign nationality or born in Sweden with at least one parent who had been born abroad. Reports, statistics and research have shown that the health of female immigrants is worse than that of the total population and that the incidence of long-term sickness absence and early retirement is higher in this group. The overall aim of this article is to describe, understand and analyze factors that contribute to poor health among female immigrants in Sweden from the perspective of class, gender and ethnicity. Being unemployed, on sick leave or working in occupation with low income and low status are examples that are related to class position, gender and ethnicity. The main three aspects based on class are wage, professional status and female immigrants position in the hierarchical work organisation. Other factors are discrimination due to ethnicity and gender, unfavourable physical and psychosocial work environment and absence of opportunities for skills upgrade training. Experiences of rape, domestic violence, unanswered emotional and sexual needs and patriarchal culture are examples that are related to gender. And experiencing traumatic events (in pre-migration periods such as experiences of war, prison, etc. and in post-migration periods such as experiences of discrimination and racism) are examples that are related to ethnicity.

    Midwives' views on factors that contribute to health care inequalities among immigrants in Sweden: a qualitative study2012In: International Journal for Equity in Health, ISSN 1475-9276, E-ISSN 1475-9276, Vol. 11, p. 47-Article in journal (Refereed)
    Abstract [en]

    Introduction: Ethnic and socioeconomic inequalities in the Swedish health care system have increased. Most indicators suggest that immigrants have significantly poorer health than native Swedes. The purpose of this study was to explore the views of midwives on the factors that contribute to health care inequality among immigrants. Methods: Data were collected via semi-structured interviews with ten midwives. These were transcribed and related categories identified through content analysis. Results: The interview data were divided into three main categories and seven subcategories. The category "Communication" was divided into subcategories "The meeting", "Cultural diversity and language barriers" and "Trust and confidence". The category "Potential barriers to the use of health care services" contained two subcategories, "Seeking health care" and "Receiving equal treatment". Finally, the category "Transcultural health care" had subcategories "Education on transcultural health care" and "The concept". Conclusions: This study suggests that midwives believe that health care inequality among immigrants can be the result of miscommunication which may arise due to a shortage of meeting time, language barriers, different systems of cultural beliefs and practices and limited patient-caregiver trust. Midwives emphasized that education level, country of origin and length of stay in Sweden play a role when an immigrant seeks health care. Immigrants face more difficulties when seeking health care and in receiving adequate levels of care. However, different views among the midwives were also observed. Some midwives were sensitive to individual and intra-group differences, while some others viewed immigrants as a group of "others". Midwives' beliefs about subgroup-specific health services vs. integrating immigrants' health care into mainstream health care services should be investigated further. Patients' perspective should also be considered.

    Foreign-Born Women's Experiences of Community-Based Doulas in Sweden - A Qualitative Study2012In: Health Care for Women International, ISSN 0739-9332, E-ISSN 1096-4665, Vol. 33, no 9, p. 833-848Article in journal (Refereed)
    Abstract [en]

    In this study our aim was to explore the experiences of doula support among foreign-born women in Sweden in the context of a “Community-Based Doula” (CBD) intervention project. We conducted interviews with ten women and analyzed the data using content analysis. Participating women reported that, in addition to support during labor; doulas provided important information and continuity of care, which apparently increased their satisfaction with and trust in maternity health care. Training of CBDs therefore has implications for delivery of equitable maternity care, which apply not only to Sweden and other European countries but wherever there are increasingly diverse populations.

    Practitioner and Client Explanations for Disparities in Health Care Use Between Migrant and Non-migrant Groups in Sweden: A Qualitative Study2013In: Journal of Immigrant and Minority Health, ISSN 1557-1912, E-ISSN 1557-1920, Vol. 15, no 1, p. 188-197Article in journal (Refereed)
    Abstract [en]

    To investigate variations in explanations given for disparities in health care use between migrant and nonmigrant groups, by clients and care providers in Sweden. Qualitative evidence collected during in-depth interviews with five ‘migrant’ health service clients and five physicians. The interview data generated three categories which were perceived by respondents to produce ethnic differences in health service use: ‘‘Communication issues’’, ‘‘Cultural differences in approaches to medical consultations’’ and ‘‘Effects of perceptions of inequalities in care quality and discrimination’’. Explanations for disparities in health care use in Sweden can be categorized into those reflecting social/structural conditions and the presence/absence of power and those using cultural/behavioural explanations. The negative perceptions of ‘migrant’ clients held by some Swedish physicians place the onus for addressing their poor health with the clients themselves and risks perpetuating their health disadvantage. The power disparity between doctors and ‘migrant’ patients encourages a sense of powerlessness and mistreatment among patients.

    Midwives' experiences of doula support for immigrant women in Sweden: A qualitative study2012In: Midwifery, ISSN 0266-6138, E-ISSN 1532-3099, Vol. 28, no 1, p. 80-85Article in journal (Refereed)
    Abstract [en]

    Objective: to describe and analyse midwives’ experiences of doula support for immigrant women in Sweden. Design: qualitative study, analysed using content analysis. Data were collected via interviews. Setting: interviews were conducted at the midwives’ workplaces. One midwife was interviewed at a cafe. Participants: ten midwives, who participated voluntarily and worked in maternity health care in western Sweden. Findings: the interview data generated three main categories. (1) ‘A doula is a facilitator for the midwife’ has two subcategories, ‘In relation to the midwife’ and ‘In comparison with an interpreter’, (2) ‘Confident women giving support, ’has two subcategories, ‘Personal characteristics and attitudes’ and ‘Good support,’ (3) ‘Doulas cover shortcomings’ has two subcategories, ‘In relation to maternity care’ and ‘In relation to ethnicity’. Key conclusion and implications for practice: The findings of this study show that midwives experience that doulas are a facilitator for them. Doulas provide support by enhancing the degree of peace and security and improving communication with the women in childbirth. Doulas provide increased opportunities for transcultural care. They may increase childbearing women’s confidence and satisfaction, help meet the diverse needs of childbearing women and improve care quality.

    Metamodelling of a Finite Element Analysis of a Drilling Process with Replaceable Inserts2019Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The aim of this project is to create a metamodel from a drilling tool with replaceable inserts from FEA of the machining process using MATLAB and ABAQUS. This report contains research in drilling and in metamodeling using neural networks and the work from the design of the CAD, through FEA and simulations, to the metamodeling, excluding the optimization.

    The work has resulted in a framework where a base FE model of the drill with two inserts that works, but due to time issues and given high cutting speed and feed the results of the FEA and the metamodeling are not very accurate. Therefore, the optimization analysis could not be done. However, it has been shown that feed has a major influence on the inserts temperature than the cutting speed, despite the higher range of this last one.

    Artificiell intelligens - ANN och evolution i shooterspel2012Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete undersöker hur två olika nätverksarkitekturer för artificiella neurala nätverk fungerar i en testmiljö av shooter-karaktär. De två arkitekturer som undersöks är ett feedforward-nätverk samt ett elman-nätverk som tränas med hjälp av evolutionära algoritmer. Skillnaden på de två valda nätverksarkitekturerna är att det sistnämnda har ett korttidsminne.

    Resultaten visar att det i den testmiljö som använts inte är någon skillnad på de två nätverksarkitekturerna, utan de uppnår i princip samma resultat. Dock så har de beteenden som nätverken uppnått visat på att det är möjligt att använda agenter som är skapade av artificiella neurala nätverk i ett shooter-spel och att de kan generera bra resultat.

    Något som inte fokuserats på i detta arbete men som skulle vara intressant att kolla vidare på, är till exempel förändring av storleken på nätverken eller att undersöka om ett långtidsminne på det rekurrenta nätverket hade förändrat resultatet.

    Procedurella Texturer: Skapande av en procedurell textur utifrån en referensbild med hjälp av en genetisk algoritm2008Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Då dataspel blir mer grafiskt tilltalande för var år som går innebär detta också att mer utrymme behövs för att få plats med alla bildtexturer. Detta leder till att spel som annars skulle kunnat läggas ut på exempelvis XBOX Live Marketplace är för stora för att få plats där. Genom att byta ut vanliga bildtexturer mot procedurella texturer skulle detta problem kunna undvikas då de senare tar mindre plats än de förstnämnda.

    Denna uppsats tar upp och redovisar en metod för att återskapa bildtexturer som procedurella texturer, där en genetisk algoritm används för att evolvera fram procedurella texturer med visuella likheter med referenstexturen.

    A Behavior-Based Model of the Hydra, Phylum Cnidaria2007In: 9th European Conference, ECAL 2007: Advances in Artificial Life, Springer Berlin/Heidelberg, 2007, p. 1024-1033Conference paper (Refereed)
    Abstract [en]

    Behavior-based artificial systems, e.g. mobile robots, are frequently designed using (various degrees and levels of) biology as inspiration, but rarely modeled based on actual quantitative empirical data. This paper presents a data-driven behavior-based model of a simple biological organism, the hydra. Four constituent behaviors were implemented in a simulated animal, and the overall behavior organization was accomplished using a colony-style architecture (CSA). The results indicate that the CSA, using a priority-based behavioral hierarchy suggested in the literature, can be used to model behavioral properties like latency, activation threshold, habituation, and duration of the individual behaviors of the hydra. Limitations of this behavior-based approach are also discussed.

    Abstract [en]

    Online social networks gained their popularity from relationships users can build with each other. These social ties play an important role in asserting users’ behaviors in a social network. For example, a user might purchase a product that his friend recently bought. Such phenomenon is called social influence, which is used to study users’ behavior when the action of one user can affect the behavior of his neighbors in a social network. Social influence is increasingly investigated nowadays as it can help spreading messages widely, particularly in the context of marketing, to rapidly promote products and services based on social friends’ behavior in the network. This wide interest in social influence raises the need to develop models to evaluate the rate of social influence. In this paper, we discuss metrics used to measure influence probabilities. Then, we reveal means to maximize social influence by identifying and using the most influential users in a social network. Along with these contributions, we also survey existing social influence models, and classify them into an original categorization framework. Then, based on our proposed metrics, we show the results of an experimental evaluation to compare the influence power of some of the surveyed salient models used to maximize social influence.

    Clustering Algorithms For Intelligent Web2016In: International Journal of Computational Complexity and Intelligent Algorithmslgorithms, ISSN 2048-4720, Vol. 1, no 1, p. 1-22Article in journal (Refereed)
    Abstract [en]

    Detecting users and data in the web is an important issue as the web is changing and new information is created every day. In this paper we will discuss six different clustering algorithms that are related to the intelligent web. These algorithms will help us to identify groups of interest in the web, which is very necessary in or- der to perform certain actions on specific group such as targeted advertisement. The algorithms under consideration are: Single-Link algorithm, Average-Link algorithm, Minimum-Spanning-Tree Single-Link algorithm, K-means algorithm, ROCK algorithm and DBSCAN algorithm. These algorithms are categorized into three groups: Hierarchical, Partitional and Density-based algorithms. We will show how each algorithm works and discuss their advantages and disadvantages. We will compare these algorithms to each others and discuss their ability to handle social web data which are of large datasets and high dimensionality. Finally a case study related to using clustering in social networks will be discussed.

    Social Networks and Recommendation Systems: A World of Current and Future Synergies2012In: Computational Social Network: Tools, Perspectives and Applications / [ed] Ajith Abraham, Aboul-Ella Hassanien, Springer London, 2012, p. 445-465Chapter in book (Refereed)
    Abstract [en]

    Recently, there has been a significant growth in the science of networks, as well as a big boom in social networking sites (SNS), which has arguably had a great impact on multiple aspects of everyday life. Since the beginnings of the World Wide Web, another fast-growing field has been that of recommender systems (RS), which has furthermore had a proven record of immediate financial importance, given that a well-targeted online recommendation often translates into an actual purchase. Although in their beginnings, both SNSs as well as RSs had largely separate paths as well as communities of researchers dealing with them, recently the almost immediate synergies arising from bringing the two together have started to become apparent in a number of real-world systems. However, this is just the beginning; multiple potentially beneficial mutual synergies remain to be explored. In this chapter, after introducing the two fields, we will provide a survey of their existing interaction, as well as a forward-looking view on their potential future.

    Explicating, Understanding and Managing Technical Debt from Self-Driving Miniature Car Projects2014In: Proceedings 2014 6th IEEE International Workshop on Managing Technical Debt: MTD 2014, Los Alamitos, CA: IEEE Computer Society, 2014, p. 11-18Conference paper (Refereed)
    Abstract [en]

    Technical debt refers to various weaknesses in the design or implementation of a system resulting from trade-offs during software development usually for a quick release. Accumulating such debt over time without reducing it can seriously hamper the reusability and maintainability of the software. The aim of this study is to understand the state of the technical debt in the development of self-driving miniature cars so that proper actions can be planned to reduce the debt to have more reusable and maintainable software. A case study on a selected feature from two self-driving miniature car development projects is performed to assess the technical debt. Additionally, an interview study is conducted involving the developers to relate the findings of the case study with the possible root causes. The result of the study indicates that "the lack of knowledge" is not the primary reason for the accumulation of technical debt from the selected code smells. The root causes are rather in factors like time pressure followed by issues related to software/hardware integration and incomplete refactoring as well as reuse of legacy, third party, or open source code.

    IT-stöd för Migrationsverket: En studie om nyttjande av beslutsstödssystem vid placeringen av ensamkommande flyktingbarn2016Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Sverige har de senaste åren konfronterats med ett ökat mottagande av ensamkommande flyktingbarn. Vid situationer som denna är det viktigt för myndigheter att fatta rättvisa beslut med rätt beslutsstödsystem.

    Denna studie inriktar sig på en undersökning hos Migrationsverket samt två kommuner där forskningsfrågan som tillämpades var ”Hur används beslutsstödsystem vad gäller placering av ensamkommandebarn i kommuner?”. Metoden som användes var kvalitativ data erhölls genom litteratursökning samt intervjuer. Studien har pågående under flera faser tillämpat Zachmans ramverk som ett hjälpmedel för att analysera erhållen data samt för att skapa intervjufrågor och genomföra intervjuer. En beslutsmodell och Zachmans ramverk har applicerats på respondenternas svar för att kartlägga respondenterna enligt modellerna. Resultatet har varit en önskan av en ökad effektivitet vad gäller beslutsfattande för kommuner och mottagandet av denna information från Migrationsverket. Idag uppfattar kommunerna sina beslutprocesser som manuella. Utifrån ett Business Intelligence (BI) perspektiv är slutsatsen av denna studie att Migrationsverket samt kommunerna behöver tillämpa ett dynamiskt samspel vad gäller beslutsfattande, integrering, mottagande av information och hantering av denna information för att fatta beslut.

    Denna studie kan användas som grund för framtida forskning där syftet är att applicera Business Intelligence (BI) behov i en verksamhet genom en tillämpning av Zachmans ramverk.

    Optimizing the Fluorescence In situ hybridization technique for a more rapid inspection of Sepsis causative pathogens by employing DNA probes2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Sepsis is a serious clinical condition that is characterized by a systemic inflammatory response syndrome resulting from a known or suspected infection. The major clinical symptoms involve an abnormal WBC count, elevated body temperature, respiration and pulse rate. Reported cases with high mortality rate range between 13 - 20 million. In order to treat Sepsis, the detection of bacteria in blood culture is extremely crucial. Treating patients with broad spectrum antibiotics is usually related to adverse effects, drug resistance, increased mortality, and high cost. In the past decades, researches had detected that E. coli and S. aureus are the major role players that cause sepsis. These microbes are molecularly tested by methods like MALDI TOF, FISH and Microarrays.  

    In this analysis, DNA fluorescence in situ hybridization (FISH) assessment for the identification of S. aureus, one of the most frequent blood pathogens, was optimized in the labs of Högskolan i Skövde. As a result, the growth of S. aureus was observed very carefully, optimizing the FISH procedure for gram positive bacteria was done and the sensitivity, stability and specificity of the DNA probe were examined under variant conditions like the continuous decrease in the bacteria cells number and utilizing a mixture of different types of bacteria cells.

    Copingstrategier hos patienter med KOL: En litteraturöversikt2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: COPD is a disease that affects the airways and the lungs. The disease is characterized by the patient having a limited airflow and the most common risk factor for COPD is tobacco smoke. COPD affects the entire lifeworld of the patient as the disease has both physical and mental impact and the patient is often in need of support. To handle stress-causing factors, people use different coping strategies, and these may vary depending on the situation, experience, and support available around the person. Aim: To describe coping strategies in patients with COPD and thereby create an understanding of these patients need for support. Method: The study is a literature review where nine articles with a qualitative approach and one article with a quantitative approach have been analyzed. Result: The result is presented with the categories Coping strategies for managing emotions and thoughts and Coping strategies that focus on change. In these categories different coping strategies of COPD patients are described in ten subcategories. Conclusion: Which coping strategies COPD-patients use depends on their lifeworld and what social and professional support is available around them. The coping strategies that focus on change are especially those who promote health, but other coping strategies are also common since the disease is associated with shame and guilt. The nurse must pay attention to the patients' coping strategies and provide them with support in implementing coping strategies that promote health.

    Steg mot Informationsvisualisering med Augmented Reality2015Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Som en del av forskningsprojektet Young Operator 2020 så syftar den här studien till att vara ett första steg mot en produkt, som med hjälp av av tekniken augmented reality ska vara en del av framtidens tillverkningsindustri. Studien utgår från kognitionsvetenskap och människa-datorinteraktion för att ha användaren och användarens interaktion med prototypen i fokus. Eftersom olika typer av användare kan behöva olika saker av ett system, kommer den här studien också att utgå från teorier om kompetensnivåer. Ett system som är användbart för exempelvis en novis behöver inte nödvändigtvis vara användbart för en expert. En prototyp har skapats som en del av ett annat projekt och den utgår från det arbetssätt som operatörer på Volvo GTO i Skövde har idag. Prototypen använder sig av augmented reality för att visualisera instruktioner. Det är tänkt att prototypen bland annat ska hjälpa noviser att närma sig expertanvändare. Ett kompetitivt användbarhetstest har gjorts där prototypen jämförts med nuvarande system på Volvo GTO. Resultatet av studien visar att prototypen i dagsläget inte kan anses vara användbar. Flera rekommendationer har dock presenterats som ett bidrag till vidareutveckling av prototypen.

    Ponies i Westport: En analys av narrativa aspekter i estetiska moddar2015Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete har fokuserat på spelarens uppfattning av estetiska moddar utifrån Mieke Bals taxonomi.Först beskrivdes den teoretiska grunden genom att förklara koncepten modd, Mieke Bals taxonomi, intertextualitet samt problematiken med Bal applicerat på visuella medier. Arbetets frågeställning sammanfattades som: hur förändras uppfattningen av ett spelnarrativ utifrån enbart estetiska förändringar och intertextualitet?För att besvara frågeställningen skapades en artefakt gjord under praktik på Double Zero One Zero baserat på deras spel The Westport Independent som ersatte representationen av karaktärerna med karaktärer från My Little Pony: Friendship is Magic. Därefter fick fem personer läsa artefakten och intervjuades enligt en semistrukturerad metod för att analysera deras uppfattningar.Resultatet visade på att även om Respondenten hävdade att detta var samma narrativ förändrades uppfattningen om den estetiska genren och karaktärerna. Därtill kunde det konstateras att deltagarna upplevde en annan tolkning av texten.

    En utredning gällande vilken information en kravspecifikation bör innehålla ur ett kontraktperspektiv1999Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Utvecklingen av informationssystem utförs vanligen med hjälp av en systemutvecklingsmodell där kravhanteringsaktivitetens (Requirements Engineering – RE-processen) syfte är att samla in och bearbeta kundens alla krav på systemet. Den slutliga produkten av RE-processen är en kravspecifikation där alla kraven gällande exempelvis systemets funktionalitet, syfte etc skall specificeras.

    Det är inte alltid självklart vilken information som en kravspecifikation bör innehålla då detta dokument kan för både kunden och leverantören ses som ett kvitto på vad som skall utvecklas och hur det skall gå till. Dokumentet skall nämligen fungera som ett underlag för de så kallade implementations- och designaktiviteterna i systemutvecklingsarbetet samt fungera som ett underlag för diskussion och kontrakt mellan leverantör och kund gällande utvecklingen av informationssystemet. Kravspecifikationen bör därför innehålla komplett och förståelig information så att detta dokument uppfyller sina syften. Därmed är det inte enkelt att veta vilken information som en kravspecifikation bör innehålla för att detta dokument skall uppfylla ovannämnda egenskaper. Då kravspecifikationen skall upprättas kan ett ramverk eller en standard tillämpas som förespråkar att viss information skall ingå.

    Det ramverk som är upprättat i detta examensarbete innehåller den information som jag anser bör ingå i en kravspecifikation. Utifrån detta ramverk finns det viss information som jag anser att en kravspecifikation bör innehålla just ur kontraktsynpunkt. Denna information är följande:

    · Informationssystemets funktioner

    · Informationssystemets funktionella egenskaper

    · Informationssystemets generella egenskaper

    · Utbildning

    · Dokumentation

    · Leveransdatum
