    Sjuksköterskans postoperativa omhändertagande av patienter som genomgått generell narkos.2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Studies have shown that the care should be adapted to the individual patient. The postoperative patient has a special need for information. The postoperative needs are ranked different by nurses and patients. Nurses find that competent caregivers, pain relief and the treatment should be a high priority. Patients feel that competent caregivers, communication and a good care are the most important needs that they have in the postoperative setting. The aim of this study is to describe nurses postoperative care of patients who has undergone a general anesthesia and who is treated at surgical ward. The study has a qualitative approach. The data has been collected through semistructural interviews. Six nurses’ have been interviewed. This study shows that information is an important aspect in the patients care. It is important to inform the patient about what is going to happen and what has happened, the patient should also inform the nurse about their condition. There should also be a communication between the different caregivers. Is it also essential that the nurses are attentive to the patient’s pain. Collaboration between caregivers and between the nurse and patient is vital for a good care. The care should be adapted to the individual needs of the patients.

    Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016: a pooled analysis of 2416 population-based measurement studies in 128·9 million children, adolescents, and adults2017In: The Lancet, ISSN 0140-6736, E-ISSN 1474-547X, S0140-6736(17)32129-3Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults.

    METHODS: We pooled 2416 population-based studies with measurements of height and weight on 128·9 million participants aged 5 years and older, including 31·5 million aged 5-19 years. We used a Bayesian hierarchical model to estimate trends from 1975 to 2016 in 200 countries for mean BMI and for prevalence of BMI in the following categories for children and adolescents aged 5-19 years: more than 2 SD below the median of the WHO growth reference for children and adolescents (referred to as moderate and severe underweight hereafter), 2 SD to more than 1 SD below the median (mild underweight), 1 SD below the median to 1 SD above the median (healthy weight), more than 1 SD to 2 SD above the median (overweight but not obese), and more than 2 SD above the median (obesity).

    FINDINGS: Regional change in age-standardised mean BMI in girls from 1975 to 2016 ranged from virtually no change (-0·01 kg/m(2) per decade; 95% credible interval -0·42 to 0·39, posterior probability [PP] of the observed decrease being a true decrease=0·5098) in eastern Europe to an increase of 1·00 kg/m(2) per decade (0·69-1·35, PP>0·9999) in central Latin America and an increase of 0·95 kg/m(2) per decade (0·64-1·25, PP>0·9999) in Polynesia and Micronesia. The range for boys was from a non-significant increase of 0·09 kg/m(2) per decade (-0·33 to 0·49, PP=0·6926) in eastern Europe to an increase of 0·77 kg/m(2) per decade (0·50-1·06, PP>0·9999) in Polynesia and Micronesia. Trends in mean BMI have recently flattened in northwestern Europe and the high-income English-speaking and Asia-Pacific regions for both sexes, southwestern Europe for boys, and central and Andean Latin America for girls. By contrast, the rise in BMI has accelerated in east and south Asia for both sexes, and southeast Asia for boys. Global age-standardised prevalence of obesity increased from 0·7% (0·4-1·2) in 1975 to 5·6% (4·8-6·5) in 2016 in girls, and from 0·9% (0·5-1·3) in 1975 to 7·8% (6·7-9·1) in 2016 in boys; the prevalence of moderate and severe underweight decreased from 9·2% (6·0-12·9) in 1975 to 8·4% (6·8-10·1) in 2016 in girls and from 14·8% (10·4-19·5) in 1975 to 12·4% (10·3-14·5) in 2016 in boys. Prevalence of moderate and severe underweight was highest in India, at 22·7% (16·7-29·6) among girls and 30·7% (23·5-38·0) among boys. Prevalence of obesity was more than 30% in girls in Nauru, the Cook Islands, and Palau; and boys in the Cook Islands, Nauru, Palau, Niue, and American Samoa in 2016. Prevalence of obesity was about 20% or more in several countries in Polynesia and Micronesia, the Middle East and north Africa, the Caribbean, and the USA. In 2016, 75 (44-117) million girls and 117 (70-178) million boys worldwide were moderately or severely underweight. In the same year, 50 (24-89) million girls and 74 (39-125) million boys worldwide were obese.

    INTERPRETATION: The rising trends in children's and adolescents' BMI have plateaued in many high-income countries, albeit at high levels, but have accelerated in parts of Asia, with trends no longer correlated with those of adults.

    Identifying design issues related to the knowledge bases of medical decision support systems2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The modern medical diagnostic systems are based on the techniques using digital data formats – a natural feed for the computer based systems. With the use of modern diagnostic techniques the diagnosis process is becoming more complex as many diseases seem to have the same pre-symptoms at early stages. And of course computer based systems require more efficient and effective ways to identify such complexities. However, the existing formalisms for knowledge representation, tools and technologies, learning and reasoning strategies seem inadequate to create meaningful relationship among the entities of medical data i.e. diseases, symptoms and medicine etc. This inadequacy actually is due to the poor design of the knowledge base of the medical system and leads the medical systems towards inaccurate diagnosis. This thesis discusses the limitations and issues specific to the design factors of the knowledge base and suggests that instead of using the deficient approaches and tools for representing, learning and retrieving the accurate knowledge, use of semantic web tools and techniques should be adopted. Design by contract approach may be suitable for establishing the relationships between the diseases and symptoms. The relationship between diseases and symptoms and their invariants can be represented more meaningfully using semantic web. This can lead to more concrete diagnosis, by overcoming the deficiencies and limitations of traditional approaches and tools.

    Barnmorskans stategier för att skapa ett positivt möte med kvinnan2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det första mötet mellan barnmorskan och kvinnan är nyckeln till en positiv upplevelse av förlossningen. Dagens förlossningsvård strävar efter att varje förlossning ska bli en unik händelse för kvinnan. Barnmorskans ansvar med bakomliggande strategier är att se till att det här första mötet blir ett lyckat möte. Syftet med denna studie var att belysa vilka strategier barnmorskan har för att skapa ett positivt första möte, där kvinnan är i ett aktivt värkarbete. Metoden som användes var intervjuer som analyserades med kvalitativ innehållsanalys. Sex barnmorskor vilka arbetar inom förlossningsvård i ett län i Västsverige deltog i studien. De svarade på fyra öppna frågor hur de skapar ett positivt första möte med kvinnan. Barnmorskornas strategier beskrivs i huvudtemat Närvarande och Lyhörd med kategorierna: Kvinnan i fokus, Skapa trygghetskänsla och Skapa delaktighet. Det framkom även hur viktigt dialogen mellan barnmorskan och kvinnan är för att sedan utveckla en relation och skapa ett positivt första möte.

    Vilka ungdomar är det som tar SMS-lån och varför?2008Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    SMS-lån är ett samhällsproblem där olika aktörer är inblandade. Utifrån treforskningsmetoder; kvantitativ- och kvalitativ undersökning samt innehållsanalys av tidningsartiklarna, har synsättet på fenomenet vidgats. Undersökningspopulationen som består av unga SMS-låntagare mellan 18-25 år, var en väldigt svår grupp att nå. Av allt att döma berodde detta på att de är en utsatt och sårbar grupp med ekonomiska svårigheter. SMS-lånet är ett snabbt och lättillgängligt lån vilket stärker ungdomarnas tendens att agera utifrån begär, som i enlighet med Maslows motivationsteori saknar en kognitiv förbindelse. Variationen var stor mellan respondenterna i fråga om vad pengarna användes till, där en del befann sig i den nedersta delen i behovstrappan för att kunna tillgodose de fysiologiska behoven, medan andra konsumerade över sina tillgångar. Låneföretagens systematiska marknadsföring förenklar för ungdomar att ta ett sådant lån med korta återbetalningstider. De ungdomar som inte betalar tillbaka lånet i tid hamnar i ekonomiska svårigheter, vilket påverkar deras liv för flera år framåt i tiden.

    Anorexia Nervosa: Friskförklarade kvinnors upplevelser kring orsaksfaktorer för insjuknande2014Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Anorexia is a global issue but occurs mainly in the Western world. Anorexia nervosa is a complex disease caused by biological, psychological, and sociocultural factors which often interacts with each other. The purpose of this phenomenological study is to gain a greater understanding of how recovered women created meaning in their illness and if there are mutual factors in their life-stories. We have especially focused on family patterns and the communication within the family. We have based our study on symbolic interactionism as our theoretical perspective. The study is of a qualitative nature and we used semi structured interviews which later were interpreted from a hermeneutic phenomenological approach. In our result we could see that creating meaning was central throughout the disease and was expressed in different ways by our respondents. Ten themes appeared and the most vital findings were that anorexia was an active action and that it is an expression for self-hatred and low self-esteem. We could also see that lack of expression regarding emotions within the families and not being emotionally recognized by their parents were crucial factors. The most important result was the respondents own perception of anorexia as a symbolizing action and the content of the disease is about so much more than weight and looks.

    Phenotypes of myopathy-related beta-tropomyosin mutants in human and mouse tissue cultures2013In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 8, no 9, e72396Article in journal (Refereed)
    Abstract [en]

    Mutations in TPM2 result in a variety of myopathies characterised by variable clinical and morphological features. We used human and mouse cultured cells to study the effects of β-TM mutants. The mutants induced a range of phenotypes in human myoblasts, which generally changed upon differentiation to myotubes. Human myotubes transfected with the E41K-β-TM(EGFP) mutant showed perinuclear aggregates. The G53ins-β-TM(EGFP) mutant tended to accumulate in myoblasts but was incorporated into filamentous structures of myotubes. The K49del-β-TM(EGFP) and E122K-β-TM(EGFP) mutants induced the formation of rod-like structures in human cells. The N202K-β-TM(EGFP) mutant failed to integrate into thin filaments and formed accumulations in myotubes. The accumulation of mutant β-TM(EGFP) in the perinuclear and peripheral areas of the cells was the striking feature in C2C12. We demonstrated that human tissue culture is a suitable system for studying the early stages of altered myofibrilogenesis and morphological changes linked to myopathy-related β-TM mutants. In addition, the histopathological phenotype associated with expression of the various mutant proteins depends on the cell type and varies with the maturation of the muscle cell. Further, the phenotype is a combinatorial effect of the specific amino acid change and the temporal expression of the mutant protein.

    Expression profiles of muscle disease-associated genes and their isoforms during differentiation of cultured human skeletal muscle cells2012In: BMC Musculoskeletal Disorders, ISSN 1471-2474, E-ISSN 1471-2474, Vol. 13, 262Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The formation of contractile myofibrils requires the stepwise onset of expression of muscle specific proteins. It is likely that elucidation of the expression patterns of muscle-specific sarcomeric proteins is important to understand muscle disorders originating from defects in contractile sarcomeric proteins.

    METHODS: We investigated the expression profile of a panel of sarcomeric components with a focus on proteins associated with a group of congenital disorders. The analyses were performed in cultured human skeletal muscle cells during myoblast proliferation and myotube development.

    RESULTS: Our culture technique resulted in the development of striated myotubes and the expression of adult isoforms of the sarcomeric proteins, such as fast TnI, fast TnT, adult fast and slow MyHC isoforms and predominantly skeletal muscle rather than cardiac actin. Many proteins involved in muscle diseases, such as beta tropomyosin, slow TnI, slow MyBPC and cardiac TnI were readily detected in the initial stages of muscle cell differentiation, suggesting the possibility of an early role for these proteins as constituent of the developing contractile apparatus during myofibrillogenesis. This suggests that in disease conditions the mechanisms of pathogenesis for each of the mutated sarcomeric proteins might be reflected by altered expression patterns, and disturbed assembly of cytoskeletal, myofibrillar structures and muscle development.

    CONCLUSIONS: In conclusion, we here confirm that cell cultures of human skeletal muscle are an appropriate tool to study developmental stages of myofibrillogenesis. The expression of several disease-associated proteins indicates that they might be a useful model system for studying the pathogenesis of muscle diseases caused by defects in specific sarcomeric constituents.

    Realtidsgenomsökning efter säkerhetsrisker i JavaScript-kod2015Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Syftet med detta arbete är att undersöka om det är möjligt att kunna i realtid undersöka kod på en webbsida för att rekommendera uppdatering av en befintlig webbläsare vid behov, utan att användarupplevelsen påverkas negativt. För att undersöka detta implementerades ett program i JavaScript. Sex olika JavaScript-bibliotek användes som testfall. Programmet söker igenom koden som finns i ett JavaScript-bibliotek och gör en rekommendation med hänsyn till några kända säkerhetsrisker och försvar mot dem. Dessutom beräknar programmet svarstiden med hjälp av klockan på klientsidan.

    Enligt Tolia, Andersen och Satyanarayanan (2006) visar undersökningar som har gjorts att användare föredrar svarstider som är under en sekund, och att svarstider som är över en sekund kan få användarna att bli missnöjda. För att användarupplevelsen inte skall påverkas negativt, bör svarstiden inte överstiga en sekund.

    Resultaten från undersökningen visar att svarstiderna inte blir tillräckligt långa för att kunna påverka användarupplevelsen negativt.

    Kvinnans förlossningsrädsla i fokus - Ur barnmorskor inom barnmorskemottagningens perspektiv: En kvalitativ intervjustudie2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Midwives working at maternal care center experience insufficient knowledge about how professional support can be offered to pregnant women. It´s important that pregnant women with tocophobia receive professional care from midwives during the entire pregnancy.

    Purpose: The aim of the study is to highlight maternal care midwives’ experiences providing professional support for pregnant women who fear of giving birth.

    Method: A qualitative interview study with inductive approach was chosen for this study to gain broader view of the BMM midwives' experiences. Seven midwives were interviewed at two BMM in southwestern Sweden.

    Results: There were two main categories "Women's fear of childbirth tokophobia". There were two subcategories "Midwife's experiences about women's lack of knowledge about fear of childbirth" and "Guide pregnant women to correct care effort". Midwives offer professional support from their own experience when women express fear of birth. This through midwives being responsive when incuayaring causes to tokophobia women. in focus" and "Midwife's need for resources and knowledge about women`s

    Conclusion: BMM midwives need continuous education about fear of childbirth in order to offer women prophetic support. BMM occupational managers should offer midwives right prerequisites for midwives to feel safe by providing care to women suffering from tokophobia.

    Abstract [en]

    The aim of this article is to identify which economic model is applied in Eritrea. The government claims to follow the market economy model(s), however, the actual practice seems to be different and casts doubts on the government's commitment to market economy. Against this background, the author has examined Eritrea's economic development model. Confirming to his doubts, the author found out that the government is applying a militarist command economy model, however, in an improperly planned, poorly coordinated and extremely mismanaged approach, with its serious negative impacts on the economic, social, cultural, diplomatic and political conditions in the country.

    Acquiring Cross-Cultural Competence: Insights from International Firms in Four Countries2016In: Entrepreneurship Development in a Globalized Era / [ed] Dana-Nicoleta Lascu, 2016, Vol. 13, 1-13 p.Conference paper (Refereed)
    Abstract [en]

    Firms increasingly have to compete globally in order to survive. An understanding of the host country’s local culture arguably being one of the most important aspects of this survival. The greater the cultural difference, the higher the risk of miscommunication and of mismanagement. Given that cross-cultural management is acknowledged as an intrinsic part of firm establishment in foreign markets today, we set out to explore the linkages between the competence of international firms in managing cultural differences and the effectiveness of their business operations. How this ‘cross-cultural competence’ is acquired is of particular interest to this study. Swedish firms operating in Kenya, Lithuania, Poland and Russia are examined. The findings show that international firms tend not to formulate any preparatory measures to become ‘culturally competent’ prior to entering foreign markets. Learning takes place by doing. A Process Model of Acquiring Cross-Cultural Competence in Foreign Markets is constructed.

    Abstract [en]

    Our understanding of the process of firm establishment of foregin firms within the developing and emerging countries remains limited, while the market-specific context-driven nature of the firm establishment process has been largely overlooked in the literature. We aim to address these omissions and explore the establishment process of a Spanish multinational telecommunication firm, Telefónica, in Brazil and Chile applying the "Four Stages Firm Establishment Process Model" by Abraha (1994). We identify strategic responses crafted by Telefónica to overcome competitive challenges during its establishment process. We revise Abraha's model in view of the findings and conclude with implications for managerial practices and future research.

    Relations and Networks in the Processes of Establishment of Firms in Transitional Economies: The case of Scandinavian firms in Eastern and Central Europe2006Report (Other academic)
    Abstract [en]

    Focus on the particular entry mode a firm uses to enter a new market, rather than the process of establishment dominates in extant literature. To fill this void, we apply an establishment process model developed from the network approach to illuminate the web of relationship forms embedded in the establishment process of two Scandinavian firms as they attempt to establish themselves in transition economies. In one case, the results show that Statoil’s process of establishment in Estonia was both less time- and resource-consuming because the firm drew support from significant actors in their network of exchange relationships. In the second case, a lack of home and host country support for Scania in Croatia resulted in an arduous and costly process and less stable position in the market, with the firm’s position changing several times as different problems cropped up. In light of the findings from the two cases, theoretical and practical implications for managing the establishment process are discussed.

    Abstract [en]

    The Scandinavian market has changed significantly over the past half-decade with several online distributors, particularly of digital files such as music, originating locally. This ineffect has significantly further increased globalization of commerce in the Nordic countries. The purpose of this research is to examine the effect of more traditional models of consumer choice regarding local vs global products in this context. While the major metro areas of Scandinavia have always been largely global, this research reaches further into the central part where attitudes and globalization tends to be adopted at a slower pace

    Establishment processes in a one party economy: the case of Eritrea2010In: African Journal of Economic and Management Studies, ISSN 2040-0705, E-ISSN 2040-0713, Vol. 1, no 1, 91-111 p.Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to address the issues of how business people perceive the business environment, how government policies impact the environment and how the environment impacts the establishment processes and position development of new firms in the Eritrean market. The process is discussed by keeping a strict focus on the main actors and the activities they carried out, as well as how the available resources are utilized and exchanged in the market.

    Design/methodology/approach – Drawing on the establishment process model developed from the network approach, case studies based on interviews and focus group discussions have been used to shed light on the extent to how government policies and the environment impacts the establishment processes and position development in the Eritrean market.

    Findings – An important conclusion of this paper is that the main obstacle for business establishment is the hostile attitude of the government to the private sector. Another significant obstacle for building a successful position in the market is the state-owned command economy network of relationships. An additional crucial hindrance is the non-existence of a market economy network of relationships that can provide firms in the private sector with the resources they need to perform their operations.

    Research limitations/implications – All firms in this paper have demonstrated that the main obstacle for establishment is the hostile attitude of the government to the private sector. Another obstacle is the state-owned command economy network of relationships, which hinders firms from building a successful position in the market. An additional crucial hindrance is the non-existence of a market economy network of relationships that can provide firms in the private sector with the resources they need to perform their operations. Since the paper is based on case studies and focus group discussions, conducting a similar study on a representative sample of firms selected from a larger population will be very useful.

    Originality/value – This paper makes a unique contribution by focusing on the establishment process in a market, which is regulated, controlled and owned by the one party government. The other unique contribution is that a firm has to identify the secrets of business success and to follow the same strategy.

    Establishment Processes in the Traditional, Complex and Fast Developing Emerging Economy: The Case of Swedish Firms in China2012In: Proceedings of the 2012 International Conference on Marketing Studies (ICMS2012), academic-journal.org , 2012Conference paper (Refereed)
    Abstract [en]

    Applying a qualitative case-study method this article examines the establishment processes of IKEA and HELDING Share Company (HSC). The findings show that establishment in China is a complex, time and resources consuming process. This is because the Chinese culture makes it a pre-requisite to build social networks of harmonious interpersonal relationships, i.e. guanxi_to achieve success. The rules are changing continuously and there is an excessive involvement of the authorities in the economic activities in the market. It thus takes time and consumes enormous resources to understand the problems and to develop strategies to achieve success in establishments. IKEA and HSC developed interpersonal networks (guanxi) with the JV partners and the various influential people (facilitators) in the different phases of establishments. The developed guanxi enabled the two firms to understand and to handle; the cultural constraint, the complicated and continuously changing legal system, the bottlenecks in authorities relationships, the most complex and time consuming bureaucratic structures, the unique style of negotiations, to get operations and import license,  license for the land for running the business and to get various types of assistance in the network development.

    The Destructive Impact of the Psychopathic and Narcissistic Leadership on the Diplomatic Dimension of Nation Building2016In: 17th International Academy of African Business and Development Conference Proceedings: May 2016, IAABD Annual Conference Proceedings, 2016, 51- p.Conference paper (Refereed)
    Abstract [en]

    Abstract: This article examines the Diplomatic Dimension of Nation building in Eritrea in light of the diplomatic vision adopted in 1994 by the so called the Peoples Front for Democracy and Justice (PFDJ). Both secondary and primary data are used to write this article. The primary data is collected through telephone interviews, personal interviews, skype-interviews and focus-group discussions with some veteran liberation fighters, former government officials, diplomats and some Eritreans who were holding key positions in the government and who have experience and knowledge as to how the narcissists and psychopaths deal with the neighboring countries and regional as well as international cooperation and relationships. The main findings show that the leadership has committed a diplomatic, moral and ethical blunder scoring one of its main failures in the diplomatic dimension of nation building. This is due to the fact that it has applied a militarist and one man owned, designed, decided and mismanaged diplomatic relationships which is not at all co-operative, although it claims that it applies a healthy neighborly, regional and international cooperation and relationships as stipulated in the diplomatic vision. Moreover, the dysfunctional militarist and one man owned, designed, decided and miss managed relationships and diplomatic approach is not properly planned and it is poorly coordinated and terribly mismanaged. This reality has a serious negative consequence on the diplomatic, economic, social, cultural, organizational and political conditions of the country. The other finding of this study is that the reason why the failed, i.e. narcissistic and psychopathic leadership applies a militarist and one man owned diplomatic relationships model is because it clearly understands that to maintain and strengthen its political, economic, cultural, organizational and social power i.e. power of all aspects it has to have a full control of all the diplomatic, economic, financial and human resources in the country. The reason why the psychopaths spear headed by the self-appointed destructive dictator do not implement the diplomatic vision is because like all the other visions envisaged in the 1994 charter, the diplomatic vision was not designed to be implemented but to help the dictator to get enough time to create the conditions necessary to implement the hidden vision which the Eritrean people couldn’t yet design appropriate strategies to fight it adequately and to dismantle its power apparatus. The last reason for the failure of the diplomatic dimension of nation building is the lack of a competent and authentic leadership that possesses the qualities of an effective, legacy building and developmental leadership.

    From industrial networks to strategic alliances or vice-versa2009In: International Journal of Business and Emerging Markets, ISSN 1753-6219, E-ISSN 1753-6227, Vol. 1, no 4, 361-386 p.Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is: to highlight the impact of industrial networks on strategic alliances; to determine if alliances help firms to build up new or strengthen existing networks; to find out whether alliances succeed or precede networks. Our findings show that well-developed networks have a positive impact on how alliances function and the results that they can achieve. The other finding is that alliances defend and strengthen networks, and also enable firms to build new ones or penetrate those of their alliance partner(s). The final conclusion is that it is difficult to determine if alliances succeed or precede networks.

    Managing Cultural Differences in International Business Operations: A Perspective from Europe2014In: Proceedings of 6th Annual American Business Research Conference 9 -10 June 2014, Sheraton LaGuardia East Hotel, New York, USA, World Business Institute Australia , 2014Conference paper (Refereed)
    Abstract [en]

    While the advantages of globalization are numerous, (including economies of scale in research and development, production, marketing, access to large and many markets, access to new ideas, technologies, competencies, resources), globalization also brings with it new challenges. Cultural differences arguably being one of the most important of these challenges. Literature suggests that cultural differences and the firms’ ability to deal with them have a significant impact on firms’ operations as well as performance. Against this background, this study explores the relationship between cultural differences and the effectiveness of international business operations. The data is drawn from a sample of North European firms operating in diverse foreign markets. The findings show that for the European firms in our sample the learning, in the main, tended to take place 'by doing' over time. The paper concludes with managerial implications.

    Kommunikation mellan sjuksköterskor och omvårdnadspersonal - en enkätstudie ur omvårdnadspersonalens perspektiv på korttidsboende2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

     

    Background: Communication is a fundamental necessity for patient security within the healthcare organization. Earlier research within the subject is largely centred around the communication between nurses and patients or nurses and physicians. Research studying communication between nurses and healthcare personnel exist to a much smaller extent.

    Aim: To explore communication with nurses within short-time residences from the perspective of the healthcare personnel and describe experiences of communication between nurses and healthcare personnel in the caring of patients at short-time residences.

    Method: Questionnaire

    Results: The results show that the healthcare personnel hold both good and bad experiences of communication with the nurses. According to the healthcare personnel, the communication is vital to provide good treatment for the patients, but also since certain workgroups function in teams. There is existing routines for communication, and the healthcare personnel experience that these routines functions well. On the contrary there is obscurity concerning routines in acute situations. Preferably, and most often, the communication is verbal. The healthcare personnel sometimes feel that the communication with the nurses is insufficient, but also found some information to be unnecessary.

    All kärlek är fin kärlek: Ungdomars kommunikation i bloggar om sex och relationer2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Under ungdomsåren förändras ungdomar fysiskt, emotionellt och kognitivt. De går in i en ny fas i livet och utvecklas från att vara barn till att bli vuxna. Under ungdomsåren etablerara och experimenterar ungdomar med vanor, attityder, tro samt livsstil. Vid ogynnsamma förhållanden kan olika riskbeteende öka. Bland ungdopmar idag ses en ökning av sexuellexponering på sociala medier. Etfersom internet idag är mer lättillgängligt än tidigare kan det medföra att ungdomar i högre utsträckning exponerar sig sexuellt, vilket kan leda till sexuella övergrepp och missbruk.

    Syfte: Är att beskriva vad ungdomar kommunicerar om i bloggar, angående sex och relationer.

    Metod: En kvalitativ innehållsanalys enligt Graneheim och Lundman användes där fem ungdomsbloggar i åldrarna 17-25 år användes och analyserades

    Resultat: Utifrån de analyserade ungdomsbloggarna framkom det två huvudkategorier; Samhällets trender påverkar ungdomars sexuella hälsa och Tillit har betydelse för relationen. Under kategorierna bildades sex underkategorier. I resultatet framkom det att ungdomar kommunicerar i stor utsträckning om sex och relationer på sociala forum. De ansåg att det idag är mer accepterat med olika sexuella läggningar och familjekonstellationer samt diskuterades dagens könsideal. Det uttrycktes en negativ syn på hormonella preventivmedel. Bloggarna uttryckte att det var viktigt med bekräftelse i en relation.

    Konklusion: Ungdomar kommunicerar brett om sex och relationer på nätet, där de har en possitiv inställning till alternativa familjekontellationer. Synen på preventivmedel var negativ bland annat på grund av dess biverkningar och de förespråkade istället hormonfria alternativ. Relationer kan påverkas av olika förändringar i livet och att vara offentlig på internet kan upplevas som ansträngande för relationen.

    Metoder vid implementation av affärssystem: en studie om anpassning2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Dagens företag är i stort behov av information. Företag som har många avdelningar behöver möjligheter för att enkelt och smidigt kunna samordna information för hela företaget. Affärssystem erbjuder denna möjlighet genom en modulbaserad konstruktion som integrerar ett företags samtliga avdelningar i ett enda system. Problem kan dock uppstå då ett valt affärssystem inte passar företagets verksamhet. En kompromiss mellan system och verksamhet måste då försöka uppnås.

    Ett affärssystem implementeras ofta i samband med en metod, vilken ger detaljerade beskrivningar för hur implementeringen ska gå till. På vilka grunder väljer företagen att arbeta efter en specifik metod då system och verksamhet behöver anpassas till varandra?

    Detta arbete bygger på en undersökning som har utförts genom en survey där fem företag har medverkat. Resultatet av undersökningen visar ett antal metoder samt presenterar orsaker till varför dessa metoder används.

    Barns språkutveckling: En kvalitativ studie om barns språkutveckling vid samlingar i förskolan2011Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this essay is to examine how children’s language is supported and developed at the kindergarten and how it is done in reality. This study has its focus on gatherings. The content of the gatherings is analyzed with the Vygotskij’s theory in mind by interviewing kindergarten teachers and observing gatherings while focusing on the three theoretical expressions involvement, participation and autonomy. The result shows that teacher use the principles of involvement, participation and autonomy by activities like reading, songs etc. The study shows even that kindergarten teachers follow two different models consisting of the Bornholmsmodel and an own model. The main function of a gathering is to involve children into a social society. It shows that gatherings have a mixed status amongst kindergarten teachers because of having different opinions about gathering’s function and relevance for developing children’s language skills. It shows that gatherings using the Bornholmsmodel do have more content than gatherings done by kindergarten teachers with their own model. To examine if this occurs because of the mixed status or because of planning-issues would be a good start to begin with in future research.

    Neuroplasticity induced by exercise2017Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    As opposed to earlier beliefs, the brain is altering itself throughout an individual’s life. The process of functional or structural alterations is referred to as plasticity, and can be induced by several factors such as experience or physical exercise. In this thesis, the research area of experience-dependent plasticity, with focus on exercise-induced plasticity is examined critically. Evidence from a vast array of studies are reviewed and compared in order to find whether physical exercise can induce neural plasticity in the human brain, how it may be beneficial, and what some of the plausible mediators of exercise-induced plasticity are. The findings demonstrated in this thesis suggest that although there are knowledge gaps and limitations in the literature, physical exercise can indeed result in exhibited plasticity as well as being beneficial for the human brain in several ways.

    Patienter som söker hälsoinformation på internet – en del av distriktssköterskors arbete.2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: District nurses work has changed over time. Today patients are more informed of their health and aware of how to influence their health. In today's society, the internet is a regular source for health information, and internet has become increasingly accessible. It is important that patients feel involved in their own care. Health care providers has a responsibility to lead the patient to reliable sources of information. Aim: The aim of this study was to shed light on district nurses' experiences of patients seeking health information on the internet and how it affects their work. Method: A qualitative approach was used. Eight interviews with district nurses were conducted. Results: From the analysis of the data, three main themes emerged which were termed; The importance of knowing and understanding, The meaning of the meeting for patients, District nurses experience and new knowledge. These themes are described by nine different sub-themes. Conclusion: The results of this study may contribute to awareness that patients seek health information on internet and that it may affect district nurses work. District nurses need to relate to patient's knowledge that varies. Patients´ knowledge demands district nurses to adapt the care and the patients visit based on their knowledge and to guide patients’ right.

    Abstract [en]

    Unstructured texts are a very popular data type and still widely unexplored in the privacy preserving data mining field. We consider the problem of providing public information about a set of confidential documents. To that end we have developed a method to protect a Vector Space Model (VSM), to make it public even if the documents it represents are private. This method is inspired by microaggregation, a popular protection method from statistical disclosure control, and adapted to work with sparse and high dimensional data sets.

    Supervised Learning Using a Symmetric Bilinear Form for Record Linkage2015In: Information Fusion, ISSN 1566-2535, E-ISSN 1872-6305, Vol. 26, 144-153 p.Article in journal (Refereed)
    Abstract [en]

    Record Linkage is used to link records of two different files corresponding to the same individuals. These algorithms are used for database integration. In data privacy, these algorithms are used to evaluate the disclosure risk of a protected data set by linking records that belong to the same individual. The degree of success when linking the original (unprotected data) with the protected data gives an estimation of the disclosure risk.

    In this paper we propose a new parameterized aggregation operator and a supervised learning method for disclosure risk assessment. The parameterized operator is a symmetric bilinear form and the supervised learning method is formalized as an optimization problem. The target of the optimization problem is to find the values of the aggregation parameters that maximize the number of re-identification (or correct links). We evaluate and compare our proposal with other non-parametrized variations of record linkage, such as those using the Mahalanobis distance and the Euclidean distance (one of the most used approaches for this purpose). Additionally, we also compare it with other previously presented parameterized aggregation operators for record linkage such as the weighted mean and the Choquet integral. From these comparisons we show how the proposed aggregation operator is able to overcome or at least achieve similar results than the other parameterized operators. We also study which are the necessary optimization problem conditions to consider the described aggregation functions as metric functions.

    STRUCTURAL ANALYSIS OF A WASHING MACHINE THROUGH ITS LOADING CASES: REDESIGN OF THE TRIPOD AND THE FRONT COVER2011Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    This project thesis is developed in collaboration with the mechanical department at University of Skövde, and it is focused in the determination of different loading cases and the application of their results to the optimization of two parts of a washing machine.

     

    The first step in this report is to obtain a numerical model of a washing machine. It includes the assembly in a mechanical software program (Abaqus), and the assignment of the specific boundary conditions and material properties for the problem. Simulation parameters such as mesh size; types of elements, and number of iterations used in the calculations will also be decided.

     

    A study of the different loading cases is carried out with the intention of having a general view of the problem and selecting four specific cases for its application to the reconstruction of the aimed parts (tripod and front cover). This study includes the calculation of the worst relative angle between the tripod and the resultant force for two opposite loads inside the drum. This angle results to be 35º between the arm and the direction of the resultant force.

     

    Through the application of these different loading conditions to this model, the mechanical behaviour of the parts will be obtained and this information will be used in the reconstruction. By mechanical behaviour it is meant to know the maximum level of stress (tension, compression and shear), and deformation (displacement and strain).

     

    Once it is well known which are the most suffering points of the tripod and in the front cover, several different new shapes are created. The parameters considered in this reconstruction were the decrease of volume, the reduction of the level of stress and the deformations. Two of these shapes are chosen and tested in the numerical model, as a checkout.

     

    Finally all these results are presented to the University of Skövde for possible future use.

    Social network analysis to influence career development2017In: Journal of Ambient Intelligence and Humanized Computing, ISSN 1868-5137, E-ISSN 1868-5145Article in journal (Refereed)
    Abstract [en]

    Social network analysis techniques have shown a potential for influencing gradu-ates to meet industry needs. In this paper, we propose a social-web driven solutions to bridge formal education and industry needs. The proposed career development frame-work utilizes social network analytics, influence diffusion algorithms and persuasive technology models along three phases: (1) career readiness to measure and visualize the general cognitive dispositions required for a successful career in the 21st Century, (2) career prediction to persuade future graduates into a desired career path by clustering learners whose career prospects are deemed similar, into a community of practice; and (3) career development to drive growth within a social network structure where social network analytics and persuasive techniques are applied to incite the adoption of desired career behaviors. The process starts by discovering behavioral features to create a cognitive profile and diagnose individual deficiencies. Then, we develop a fuzzy clustering algorithm that predicts similar patterns with controlled constraint-violations to construct a social structure for collaborative cognitive attainment. This social framework facilitates the deployment of novel influence diffusion approaches, whereby we propose a reciprocal-weighted similarity function and a triadic clo-sure approach. In doing so, we investigate contemporary social network analytics to maximize influence diffusion across a synthesized social network. The outcome of this social computing approach leads to a persuasive model that supports behavioral changes and developments. The performance results obtained from both analytical and experi-mental evaluations validate our data-driven strategy for persuasive behavioral change.

    A social learning analytics approach to cognitive apprenticeship2015In: Smart Learning Environments, ISSN 2196-7091, Vol. 2, no 14Article in journal (Refereed)
    Abstract [en]

    The need for graduates who are immediately prepared for employment has been widely advocated over the last decade to narrow the notorious gap between industry and higher education. Current instructional methods in formal higher education claim to deliver career-ready graduates, yet industry managers argue their imminent workforce needs are not completely met. From the candidates view, formal academic path is well defined through standard curricula, but their career path and supporting professional competencies are not confidently asserted. In this paper, we adopt a data analytics approach combined with contemporary social computing techniques to measure, instil, and track the development of professional competences of learners in higher education. We propose to augment higher-education systems with a virtual learning environment made-up of three major successive layers: (1) career readiness, to assert general professional dispositions, (2) career prediction to identify and nurture confidence in a targeted domain of employment, and (3) a career development process to raise the skills that are relevant to the predicted profession. We analyze self-declared career readiness data as well as standard individual learner profiles which include career interests and domain-related qualifications. Using these combinations of data sources, we categorize learners into Communities of Practice (CoPs), within which learners thrive collaboratively to build further their career readiness and assert their professional confidence. Towards these perspectives, we use a judicious clustering algorithm that utilizes a fuzzy-logic objective function which addresses issues pertaining to overlapping domains of career interests. Our proposed Fuzzy Pairwise-constraints K-Means (FCKM) algorithm is validated empirically using a two-dimensional synthetic dataset. The experimental results show improved performance of our clustering approach compared to baseline methods.
