    Bildklassresa mellan konststilar och epoker: om bildlärares konstsyn och teknikval i grundskolans bildundervisning2014Självständigt arbete på avancerad nivå (magisterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose of this study was to to examine what teachers think about visual art and how the learning process in this subject does look like. To answer these issues, I made interviews with five teachers of visual art from different schools, and I examined several examples of pupils’ artworks. The stories of the teachers were analyzed in relation to governing documents and with assumptions from sociocultural theory, postmodernism and pedagogical - aesthetic research as theoretical point of view.

    By the qualitative interview method, the observations of the pupil’s artworks, and by the analysis of the interviews with the teachers, I have come to the conclusion that teachers think differently about art but they try to keep themselves in line with the national governing documents. Its affects aspects of disciplines, styles, techniques and medium that is exemplified by the pupil’s art works, and it points out similarities and differences between the pupil’s art works and between the teachers when teaching visual art.

    Konst på internet idag: En retorikanalys av konstverksamma organisationers självpresentationer2014Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This is a qualitative study about Art transformation and commodification in the digital age. The study applies a rhetoric analysis with the aim to understand how art sellers, gallery owners and entrepreneurs take part in this transformation process through their websites’ presentation texts ”about us”. The analysis is related to communication theories but it is also inspired by other theories such as Gramsci’s hegemony theory and Bourdieu’s cultural critical theory. The study shows that in an environment of ”Global Communication”, activities that are related to the visual art on the net are strongly influenced by the commodification. Marketers and business managers have a big advantage of this phase of change in Art activities on the net. As senders in a one-way communication process, they use their rhetorical skills in their presentation texts to build identities or to enhance their business, depending on the positions of power they have in the market. They invest in art and artists, in order to expand their businesses and to capture a wider audience of recipients on World Wide Web to get more money and power. The study recommends further research about the Art commodification, preferably from the receiver’s and the artists’ sides to reveal more aspects of the effects of this transformation process in Art and its values.

    Parents’ experiences of transitioning to home with a very-low-birthweight infant: a meta-ethnography2023Ingår i: Journal of Neonatal Nursing, ISSN 1355-1841, E-ISSN 1878-089X, Vol. 29, nr 3, s. 444-452Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Medical-technological advances and neurodevelopmental care have improved the survival of extremely- and very-low-birthweight infants born before 32 weeks' gestation. After months in neonatal care, the infants are discharged, and parents exited but full of anxiety. This review is designed as a meta-ethnography, addressing parents' discharge experiences to comprehend the synthesised research, which includes 12 eligible studies. From the analysis, we constructed three themes: ‘approaching discharge with both uncertainty and confidence’; ‘discharge as a longed-for though disordering turning point’; and ‘facing joys, worries and multiple challenges when at home’. The overarching interpretation was ‘discharge as double-edged sword’. We conclude that bringing home very-low-birthweight infants is a joyful event, yet parents also experience discharge as never-endingly worrying, as a time filled with challenges to which parents must adapt and as necessitating continuous support from knowledgeable providers.

    Upper bounds on the number of perfect matchings and directed 2-factors in graphs with given number of vertices and edges2015Ingår i: European journal of combinatorics (Print), ISSN 0195-6698, E-ISSN 1095-9971, Vol. 45, s. 132-144Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We give an upper bound on the number of perfect matchings in simple graphs with a given number of vertices and edges. We apply this result to give an upper bound on the number of 2-factors in a directed complete bipartite balanced graph on 2n vertices. The upper bound is sharp for even n. For odd n we state a conjecture on a sharp upper bound.

    Governance patterns and performance of regional strategies in peri-urban areas: comparative analysis of seven cases in Europe and Chine2011Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This report examines how different regional and local governance patterns and specific spatial planning strategies impact on peri-urban land use in Rural Urban regions. It draws from seven regional case studies, presenting a diverse mix of strategies ranging from protecting biodiversity and agricultural land, creating recreation and tourism opportunities to reducing pressure from building and infrastructure development. To study the means of influence or power an analytical framework of ‘policy arrangement’ was employed (Tatenhove et al, 2000): specifying rules of the game, resources, coalitions and discourses. Both government and nongovernment actors such as environmental groups or developers can form coalitions, adopt rules, employ resources and develop discourses to influence policies and developments in urban regions. The analytical and assessment frameworks defined by regional researchers and practitioners helped to organize the case study data and to evaluate both processes and outcomes of governance in peri-urban areas. The outcomes are represented in a summarized way for each strategy and region.

    The report provides examples of unsustainable developments in peri-urban regions and how certain strategies helped to counteract these, and emphasizes the importance of recognizing peri-urban areas as a policy field in its own right.

    A sustainable spread of land use over the Rural Urban region requires regional authorities whose jurisdiction covers the Rural Urban region and who have the appropriate mix of policy means of influence and relative power over lower level authorities. Under the current predominant discourse of ‘sustainable’ development largely being equal to economic development, the outcome of sustainability concerns depends on urban areas taking financial responsibility for the inclusion of common good interests such as ecosystem services, cultural heritage and social and environmental justice into the periurban areas. Recommendations for policy makers at different levels conclude the report.

    Home  Peri-urban futures: Scenarios and models for land use change in Europe  ChapterGovernance and Sustainability of Peri-Urban Areas: A Comparative Analysis of the PLUREL Case StudiesCarmen B. E. M. Aalbers & Katarina Eckerberg ChapterFirst Online: 01 January 20122144 Accesses2 Citations2 AltmetricAbstractThis chapter examines the analyses and strategies presented for each of the case studies in Chaps. 4, 6, 7, 8, 9, 10 and 11 and presents a comparison in order to draw out the main findings which may provide possible solutions for policy makers working in other regions. As explained in Chap. 1, there are a range of particular policy challenges in the urban fringe. The policies of several adjacent municipalities or local authorities may be combined and managed by an indirectly elected regional authority, while different national and EU-level sectoral and regional policies frequently interfere with each other in such areas. Problems of implementation deficits with sector-based strategies are commonplace following institutional fragmentation, calling for increased co-ordination and better integration mechanisms (Tatenhove et al. 2000).

    Biodiversity and habitat conditions in reaches with high flow velocity along gradients in hydrological and geomorphological alteration: A study of six rivers in Sweden2021Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The vast majority of rivers in the developed world are affected by human alteration, which in turn negatively affects the species that rely on these highly diverse and species rich areas to survive. Homogenization of previously heterogenic areas due to a change in water discharge and the substrate availability in the rivers is often regarded as the main reason for the loss of species richness in rivers and the riparian zone. Because of this, there are a lot of restoration projects which main goal is to increase heterogeneity. The goal of this thesis is to compare hydrology and geomorphology variables between four types of reaches with high flow velocity (rapids in free-flowing reaches, rapids with regulated flow, impounded reaches and reaches in outlet channels below hydropower plants). In this thesis I wanted to find out how changes in geomorphology and hydrology affect fish species richness, riparian vegetation richness and aquatic vascular plants species richness. The result show that both fish species richness and riparian vegetation species richness are negatively affected by the changes in geomorphology and hydrology. There was no significant difference for aquatic vascular plants when comparing the regulation types. The most altered reach type, outlet channels, had significantly fewer fish species compared to the less altered reach type, impounded reaches. Outlet channels also had less riparian vegetation cover compared to all other regulation types, and fewer riparian vegetation species compared to both free-flowing reaches and impounded reaches. In conclusion, hydropower plants and timber floating have both negatively impacted the riverine ecosystem, and in turn caused a decrease in species richness for fish and riparian plants. The reaches studied in this thesis will continue to be altered and the species richness and species composition will change from an ecosystem that relied on the natural flow regime to an ecosystem more used to the flow regime created by the hydropower plants.

    Kanalisering och restaurering av vattendrag påverkar mossamhällen i strandzonen: -En studie av Vindelälvens biflöden2018Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This study compared three different types of reaches at streams and how bryophyte species richness, diversity and abundance in the riparian zone differ between them. The different types of reaches are those that have been treated by two types of restoration techniques (best practise and advanced) and streams that have still not been restored (channelized). The bryophytes were gathered from 15 tributaries to Vindelälven, which is in northern Sweden. Bryophyte species richness and diversity was highest at the streams that were still not restored, and I found numerous factors that could explain why this was the case. Fourteen environmental variables were tested against the three bryophyte factors to try to explain the variation found in the study. Time since restoration and the amount of tree biomass in the area could explain the species richness found at the different river types. The study shows that short-term effects of restoration on the riparian zone is a decrease in bryophyte species richness and diversity. However, given enough time the bryophytes are expected to recover in regards to species richness and diversity.

    Säkerhet eller produktion först?: En kvalitativ studie om säkerhetsarbete på en processindustri i Sverige2020Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Ett fungerande arbetsmiljö och säkerhetsarbete är viktigt för att förebygga olyckor i arbetet. Därför är det intressant att undersöka hur säkerhetsarbetet i en processindustri upplevs, en organisation där medarbetare dagligen utsätts för risker i arbetet. Genom kvalitativa intervjuer har problemområdet undersökts i syfte att identifiera aspekter som påverkar säkerhetsarbetets förutsättningar. Studiens resultat visar att säkerhetsarbete är ett komplext område där organisatoriska, tekniska och kulturella aspekter kontinuerligt samspelar. Att säkerhet ständigt tävlar om prioritet mot produktionen är dessutom en ständig utmaning.

    Nervrotsblockad i kombination med fysioterapi för patienter med diskbråck - en single subject experimental design2017Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Introduktion: Diskbråck i ländryggen med symtom av ischias, bensmärta, är en vanlig orsak till specifika ryggbesvär. Konservativa behandlingsmetoder rekommenderas före kirurgi. Diagnosen diskbråck är förknippad med kraftig smärta och begränsningar och är en vanlig orsak till att söka vård och behandling. Trots detta finns det idag ingen konsensus kring vilka behandlingsmetoder som är mest effektiva vid diskbråck.

    Syfte: Att undersöka effekten av nervrotsblockad i kombination med individanpassad fysioterapi på smärta och aktivitetsförmåga för patienter med symtomgivande lumbosakralt diskbråck.

    Metod: Studiens utformning var en Single Subject Experimental Design (SSED), med en A-B design. Under baslinjefasen, A och interventionsfasen, B utfördes systematiska och upprepade mätningar av smärtintensitet och aktivitetsförmåga över tid. Totalt fem patienter med lumbosakralt diskbråck rekryterades från en klinik. Studien omfattades av två interventioner. Två patienter behandlades med nervrotsblockad (NRB) i kombination med individanpassad fysioterapi och tre patienter behandlades endast med NRB. Mätdata presenteras med grafer i linjediagram och analyserades visuellt.

    Resultat: De två patienterna som fick NRB i kombination med individanpassad fysioterapi förbättrades avseende smärta respektive aktivitetsförmåga, under nio respektive fem veckors interventionsfas. Av de tre patienter som behandlades enbart med NRB upplevde en patient en försämring avseende smärta och aktivitetsförmåga, en valde att avsluta sin medverkan och en behandlades som bortfall.

    Slutsats: NRB i kombination med individanpassad fysioterapi kan minska smärta och förbättra aktivitetsförmåga för enskilda patienter med symtomgivande lumbosakralt diskbråck.

    The Sami Representations Reflecting the Multi-Ethnic North of the Saga Literature2017Ingår i: Journal of Northern Studies, ISSN 1654-5915, E-ISSN 2004-4658, Vol. 11, nr 2, s. 7-30Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article focuses on contextualizing the Sami (finnar) representations in Old Norse saga literature. The purpose is to show that the Sami representations reflect multi-layered Old Norse textual and oral traditions, and complex interaction between the Sami and the Norwegians in the Middle Ages. The stereotypes of the Sami tell us more about the society that created them than about real, historical events. We can be sure that behind them lie very mundane phenomena such as trade and marriages.

    The ultimate goal of the article is therefore to reveal the multi-ethnic North that provided the background for the saga sources, a North whose history is not as homogeneous as sources suggest and quite unlike the modified version which found its way into the histories of nation states. The literary conventions of sagas are not just imaginary tales—their use in various contexts can reveal something essential in otherwise schematic images or configurations. Even researchers of the sagas have certain personal conceptions of what the “real” lives of the Sami were like at the time, and how the sagas depict this. In fact, they participate in a continuum of saga literature that generates representations of the Sami in history.

    Assessing the Preparedness of Small and Medium-sized Entities in Sweden: to Adopt International Financial Reporting Standard (IFRS) for Small and Medium-sized Entities (SMEs).2010Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    SMEs serve as a backbone to keep an economy going and to boost it up in times of difficult hours like recession, for example. They are considered as the main source of modernization, innovation and entrepreneurial spirit. Like rest of Europe, 99% of enterprises are SMEs in Sweden which form a ratio of approximately 58 SMEs per 1000 inhabitants. Moreover SMEs employ around 60% of Sweden‟s manpower which shows their concern toward social responsibility.

    Several companies irrespective of their size are bound by the statutory rules of a particular country in which they operate to prepare financial reports that conform to specified set of accounting principles. There has been much ongoing debate regarding the suitability of one set of accounting standards in a country for all its operating enterprises, regardless of their size. In July 2009 the International Accounting Standards Board (IASB) published the International Financial Reporting Standard (IFRS) for Small and Medium-sized Entities (SMEs). The IFRS for SMEs is intended to be applied to the general purpose financial statements of entities that do not have public accountability. The main theme of our thesis is to examine the suitability and difficulties faced by SMEs in Sweden towards IFRS for SMEs. Furthermore, this thesis will identify the problems that will be faced by SMEs in Sweden, in the process of adopting IFRS for SMEs. Lastly, this study will be conducted to check whether SMEs in Sweden prefer to choose and use IFRS for SMEs or Swedish GAAP.

    In order to achieve the determined objectives, the study "Assessing the preparedness of small and medium-sized entities in Sweden to adopt International Financial Reporting Standard (IFRS) for Small and Medium-sized Entities (SMEs)" was conducted. A qualitative research employing semi-structured interviews was carried out with eleven interviews in order to solidify the quality criteria of our research work. Sample was selected based on convenient sampling from Umeå due to the limitations of resources in terms of cost and time; opinions from three different categories of respondents (audit firms, SMEs and experts‟ opinion from the academic perspective) would be gathered. All collected data would be analyzed against the theoretical framework, and with the help of analysis conclusion regarding this study would be drawn.

    Based on the qualitative results, the findings exhibits that SMEs in Sweden are not inclined towards IFRs for SMEs and are not ready in any way to adopt these standards. The Swedish GAAP has been designed over years and all SMEs are very much familiar with the rules and principles applicable in Swedish GAAP. Therefore, according to our research inclination of SMEs in Sweden is towards Swedish GAAP rather than IFRS for SMEs.

    Auditor client relationship and audit Quality: The effects of long-term auditor client relationship on audit quality in SMEs2011Självständigt arbete på avancerad nivå (masterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Different scandals around the globe during the past, in specific during the last decade, have intrigued the stakeholders to question the roles of both auditors and management. But most of the fingers since then have been raised on the role of auditors, because it is the auditors who are entrusted with the responsibility to detect any errors or frauds in the financial reports of the client-firm. Apart from this, the long-term auditor client relationship has been the center of attention in most of the discussions and debates as well. Numerous studies have been conducted by the academic researchers, financial and professional analysts, regulatory authorities and governing bodies, and in some cases by the auditors and the firms as well regarding the effects of long-term auditor-client relationship on audit quality, equity risk premium, financial reports quality, audit pricing etc. These studies provide us with different results, both with the positive and negative associations and effects of long-term auditor-client relationship on the basis of different factors and contexts.

    For long, auditing has been discussed in different studies and research areas but mostly in association with publicly listed companies. Less attention has been paid to the relationship of auditors and clients as far as clients in SMEs are concerned. In any country around the globe, SMEs are of major contribution in terms of backing the economy, giving it both the boost and the stability, as they collectively form the major chunk of the economy. If we specify our study to the SMEs in Sweden, then 99% of the enterprises in Sweden represent the SME sector; in addition they employ around 60% of the manpower. Based on these facts, and due to less attention given to auditor-client relationship in terms of SMEs, instead of; we have directed our concerns towards the study of effects of auditor-client relationship on audit quality in SMEs in this particular research study.

    In this study, we have opted for qualitative research with semi-structured interviews to be used as the tool for data collection. Interviews were conducted with two different groups of interviewees, one group representing the auditors and the other group representing the client-firms (SMEs). A total of seven interviews were conducted in order to strengthen and validate the results for our research question. Due to the limitations of this study, mostly in terms of cost and time, samples were selected from Umeå, Sweden. The data interview structure, data analysis and discussion, and conclusions were all made based on existing theories summarized in the theoretical review of this study. The results of this study suggests that (1) long-term audit tenure is beneficial for the audit quality if certain risk factors like risk of auditor independence and risk of developing complacency are controlled; and (2) factors such as NAS, industry specialization, knowledge and experience of the auditor, internal control in the client-firm, professional ethics, proper audit plan, providence of unbiased information by the client, and appointment of the auditor by the client-firm itself enhances the audit quality.

    Customer Value's Influence on International Market Entry Strategies in a B2B Context: Business and Market Opportunities in the Data Centre Segment in Northern Europe2016Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    nternational market entry strategies gained increasing importance due to globalisation. Companies became multinationals. Therefore, new challenges arose due to different market and customer requirements. One topic, which gained importance in B2B context, is customer value. Customer value can be defined as the perceived benefits a company delivers its customers in comparison to the perceived expenses. Nevertheless, no uniform definition exist. In addition to that, if there is a direct connection between B2B customer value and international market entry strategies have not been investigated yet. Therefore, this thesisprojectdeals with the influence of B2B customer value on international market entry strategies. To determine the link, following research question guides this thesis: How does B2B customer value influence international market entry strategies in Northern Europe?The research isnot only focused on Northern Europe but also on the data centre segment. The investigated countries are Norway, Ireland, UK and Finland. These countries are highly interesting for the commission partnerdue to market developments and mega trends. Furthermore, the commission partneris represented by local subsidiaries in the four countries of interest. In order to answer the research question, deep insights are generated via semi-structured interviews. Three customer groups are investigated: Data centre operator as well as owner, constructors including panel builder and system integrators as well as design consultants. The interviews are conducted either face-to-face or if necessary via telephone in the four countries of interest. The interviews include questions about B2B relationships, brand and marketing.If culture influences B2B customer value is investigated indirectly bythe questions on B2B relationship.Market intelligence questions are added in order to create a deeper understanding of the market.Furthermore, these insights also help to interpret the answers of customers. Due to the interviews, a picture of the B2B customer value in Northern Europe is created. Northern European customers value reliable suppliers who can offer quality products as well as solutions. In addition to that, the importance of global brands andmarketing of competences is determined. Due to combining the findings with the cultural dimensions of Hofstede, it is concluded that customer value differs between other countries.Hence, customer value influences international market strategies, as different customer value require distinct international market entry strategies.

    Övergång, en stadig bro eller en tunn röd tråd?: En intervjustudie om barns övergång mellan förskola och förskoleklass sett ur ett organisatoriskt perspektiv2022Självständigt arbete på grundnivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Studien tar sin utgångspunkt i barns övergångar från förskolan till förskoleklassen med fokus på det organisatoriska perspektivet. De två skolformerna ska samverka och utbyta information om barnens utveckling och lärande i syfte att främja progression i ett långsiktigt perspektiv. Det är sparsamt med nationell forskning som inriktat sig på skolformernas organisatoriska förutsättningar att gestalta likvärdiga övergångar utifrån de uppdrag styrdokumenten förespråkar. Studiens syfte har varit att bilda kunskap om hur förskollärare i förskolan och lärare i förskoleklassen beskriver övergångsprocesser och hur ansvarsfördelningen mellan förskolan, förskoleklassen och huvudmannen kan förstås. För att undersöka ovan nämnda syfte föll valet på kvalitativ metod där semistrukturerade intervjuer genomförts med tre förskollärare i förskolan och tre förskollärare/lärare i förskoleklass.Den insamlade empirin har bearbetats genom kvalitativ analys som visar att brist på tid för samverkan och otydlig styrning är centrala utmaningar för både förskolan och förskoleklassen. Behov av tydligare styrning av övergångsprocesser diskuteras samt behov av framtida forskning kring förskollärares och lärares förutsättningar att gestalta övergångar. Vad som ska göras finns tydligt beskrivet i styrdokument men hur är frågan som behöver rätas ut för att främja jämlika övergångar för barn.

    En intuitiv & lättillgänglig flyktmask för gruvmiljö2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    I have always lived around mines and around people work­ing with mines. They are a natural part of my life and, inev­itably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.

    In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.

    Throughout the project I’ve been working with a context which is heavily regulated, and all problems are serious, important ones. I have been striving towards keeping a high level of innovation during the process, whatever the result in the end might be. I’ve been heavily relying on scenarios/workflows, product testing, observation, and I’ve had the great joy to be able to take part of LKABs accident reports.

    The concept can be divided into three parts, but it is the way these collaborate that makes out the main part of the concept.

    1: An escape station, providing a standardized placement of escape hoods.

    2: A container for the vacuum sealed escape hood.

    3: An escape hood which enables a personalized fit for the user.

    Interactive surfaces are color coded with the goal to provide an intuitive workflow. When the container is opened, the vacuum seal is immediately broken and the user gains access to two handles, one white and one red. The handles are used to lift and apply the escape hood, and the red handle is then used, by pulling, to tighten the throat fit.

    Combined, these solutions help the user applying her escape hood in shorter time, and a large head size, glasses, beard and a thick neck are no longer problematic for the applica­tion

    The Joy of Riding2015Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    2045 a progressive European city is banning driving and BMW has to respond. Technological evolution, and a culture used to new interfaces leads to the option to recreate the relationship between human and car. But how to interact with our new friends?

    Talking to experts in the fields of science fiction, environmentalism, horse riding and piloting helped in first constructing a future and then tailoring an interface-vision for its inhabitants and their autonomous cars.

    The result is a tactile bond connecting driver and machine. Working together with your car doesn't have to mean loosing control, it's just another quality of control.

    Nyckeln till jämlik studie- och yrkesvägledning av hög kvalitet?: En policystudie av det dokumenterade systematiska kvalitetsarbetet med inriktning studie- och yrkesvägledning2020Självständigt arbete på grundnivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Som ett komplement till de undersökningar som visar att det systematiska kvalitetsarbetet med inriktning studie- och yrkesvägledning inte genomförs av alla skolenheter och huvudmän syftar denna policystudie till att, genom dokumentanalys av tre gymnasium med respektive huvudmans dokumenterade kvalitetsarbete, ge en inblick i hur det görs. Studiens tre specifika frågeställningar är:

    • Hur kan det systematiska kvalitetsarbetet, med inriktning studie- och yrkesvägledning beskrivas utifrån dokumentationen?
    • I vilken utsträckning är det studerade dokumenterade arbetet förenligt med de riktlinjer som finns?
    • Vilka skillnader återfinns i det dokumenterade arbetet huvudmän och enheter emellan?

    Resultatet, som baseras på data från tre gymnasieskolor med huvudmän, visar att det finns variationer i innehåll och genomförande av det dokumenterade systematiska kvalitetsarbetet med inriktning studie-och yrkesvägledning mellan enheter och mellan kommuner. Innehållet, eller i vissa fall bristen på innehåll pekar på att reglering av systematiskt kvalitetsarbete och studie- och yrkesvägledning inte har resulterat i det systematiska kvalitetsarbete och den studie- och yrkesvägledning som var tänkt.

    I den studerade dokumentationen kan okunskap om både studie- och yrkesvägledning och systematiskt kvalitetsarbete samt brist på kontinuitet och mätbara relevanta mål skönjas som förklaringar till glappet mellan intention och praktik. Det finns dock anledning att, med hjälp av den teoretiska referensramen policyenactment, beakta och diskutera mer komplicerade underliggande processer i fråga om tolkning, relationer, motstånd och performativitet som hinder för utveckling av jämlik studie- och yrkesvägledning, av hög kvalitet, enligt de riktlinjer som finns i dagsläget.

    Scholars' open debate paper on the World Health Organization ICD-11 Gaming Disorder proposal2017Ingår i: Journal of Behavioral Addictions, ISSN 2062-5871, E-ISSN 2063-5303, Vol. 6, nr 3, s. 267-270Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    Concerns about problematic gaming behaviors deserve our full attention. However, we claim that it is far from clear that these problems can or should be attributed to a new disorder. The empirical basis for a Gaming Disorder proposal, such as in the new ICD-11, suffers from fundamental issues. Our main concerns are the low quality of the research base, the fact that the current operationalization leans too heavily on substance use and gambling criteria, and the lack of consensus on symptomatology and assessment of problematic gaming. The act of formalizing this disorder, even as a proposal, has negative medical, scientific, public-health, societal, and human rights fallout that should be considered. Of particular concern are moral panics around the harm of video gaming. They might result in premature application of diagnosis in the medical community and the treatment of abundant false-positive cases, especially for children and adolescents. Second, research will be locked into a confirmatory approach, rather than an exploration of the boundaries of normal versus pathological. Third, the healthy majority of gamers will be affected negatively. We expect that the premature inclusion of Gaming Disorder as a diagnosis in ICD-11 will cause significant stigma to the millions of children who play video games as a part of a normal, healthy life. At this point, suggesting formal diagnoses and categories is premature: the ICD-11 proposal for Gaming Disorder should be removed to avoid a waste of public health resources as well as to avoid causing harm to healthy video gamers around the world.

    Abstract [en]

    Objective:The primary aim was to assess, the association of the quantity and quality of dietary fat intake from 6 to 12 months of age and serum lipids at 12 months.Subjects/Methods:Three hundred healthy term Swedish infants were recruited in a longitudinal prospective study at the age of 6 months; 276 remained in the study at 12 months. Food records and anthropometric data were collected monthly from 6 to 12 months; serum lipids were analysed at 6 and 12 months.Results:Swedish infants had a total fat intake within the Nordic recommendations, but intake of polyunsaturated fatty acids (PUFA) was low (5.6 percent of total energy (E%)) and intake of saturated fatty acids (SAFA) was high (15.1 E%). Higher PUFA intake was associated with lower total serum cholesterol (TC, B=-0.13, P=0.003), lower low-density-lipoprotein cholesterol (LDL-C, B=-0.12, P=0.004) and apolipoprotein B (B=-0.03) (P=0.034) in girls but not in boys. When data from the present study were compared to data from similar studies in Finland and Iceland, it appears that the quality of the dietary fat has greater impact on serum lipid levels than the quantity of fat in the diet.Conclusions:Higher PUFA and lower SAFA intakes may reduce TC and LDL-C early in life, particularly in girls. Further, with respect to lowering serum lipid concentrations in early childhood it seems appropriate to set focus on fat quality rather than the quantity.Sponsorships:Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (Formas), Swedish Research Council, Medicine, Stiftelsen Oskar Foundation, Sven Jerring Foundation, Samariten Foundation, Stiftelsen Goljes minne and Semper AB.European Journal of Clinical Nutrition advance online publication, 20 June 2007; doi:10.1038/sj.ejcn.1602824.

    The future of greying Europe: Conclusion2013Ingår i: Old age in Europe: A textbook of gerontology / [ed] Komp, K., & Aartsen, M., Dordrecht: Springer Netherlands, 2013, s. 131-136Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Although Europe’s population is greying, the future of Europe does not look grey. What can be learned from this book is that old age is not necessarily characterized by frailty and decline, but instead can be a time of self-fulfillment, activity, and social participation. Moreover, we now know that population ageing does not need to threaten extant social and welfare state-related institutions, but instead opens up potentials for restructuring and reinvention. Life expectancy is longer than ever before and living conditions that enhance healthy ageing have very much improved. New technologies and Information and Communication Technologies may assist older people to stay in their homes longer. The growing possibilities to reach a good old age may have given rise to what is sometimes called ‘a silver economy’: an economy with all kinds of new products and services, particularly aimed at the growing share of healthy and wealthy senior citizens. The greying of Europe might, thus, ultimately lead us into a bright and colourful future.

    "Så länge ni sköter er bra och det verkar ni göra så är jag nöjd, så behöver jag inte lägga mig i": En kvalitativ studie om första linjens chefers psykosociala arbetsmiljö inom regional hälso- och sjukvård2021Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Anställda spenderar en stor del av sin tillvaro på arbetsplatsen och den psykosociala arbetsmiljön blir då en viktig faktor för att främja ett längre och mer hållbart arbetsliv. Rollen som första linjens chef kräver idag stor kunskap och förmåga för att hantera de krav som finns från organisation, medarbetare, chefer samt lagar och förordningar. Det är därför av stor vikt att arbetsgivare och organisationer har väl fungerande strukturer och processer för att följa upp sina chefer och medarbetares psykosociala arbetsmiljö. Syftet med studien var att bidra med en ökad förståelse för hur första linjens chefer inom regional hälso- och sjukvård upplevde sin psykosociala arbetsmiljö, hur de ansåg att den borde kartläggas och följas upp samt påvisa vilka behov cheferna har för uppföljning av den. Studien syftade till att få fram chefernas egna tankar och upplevelser kring deras psykosociala arbetsmiljö. För att undersöka detta användes en kvalitativ ansats med semistrukturerade intervjuer. Resultatet visade att chefernas relation till sin närmsta chef var avgörande för hur de upplever sin psykosociala arbetsmiljö och i sin tur vilka behov de hade för uppföljning och stöd. De chefer som beskrev en god relation till sin verksamhetschef upplevde i större utsträckning att deras behov av uppföljning tillgodosågs till skillnad mot de chefer som upplevde en sämre relation till sin verksamhetschef. De chefer som beskrev en sämre relation till sin verksamhetschef beskrev att behoven i mångt och mycket skulle tillgodoses om relationen till verksamhetschefen vore bättre. De slutsatser som kunde dras var således att relationen och kommunikationen med närmsta chef var avgörande för hur man upplevde sin psykosociala arbetsmiljö. Cheferna beskrev även att det fanns ett stort behov av fler informella möten med chefskollegor och att deras psykosociala arbetsmiljö skulle gynnas av att ha en mindre arbetsgrupp.

    Abstract [en]

    This article examines and compares principal training programs in Sweden and Norway, the two Nordic countries with national leadership programs for already active school leaders. To investigate the knowledge base and design of the programs we draw on two research-derived tools about successful professional learning programs for school leaders. Based on the examinations, we suggest that the programs reflect international research both in terms of content and process factors. In addition, we identify topics and issues, such as balancing democratic participation with managerial decision-making, which can be characterized as making up a Nordic profile.

    Individualized low-load motor control exercises and education versus a high-load lifting exercise and education to improve activity, pain intensity, and physical performance in patients with low back pain: a randomized controlled trial2015Ingår i: Journal of Orthopaedic and Sports Physical Therapy, ISSN 0190-6011, E-ISSN 1938-1344, Vol. 45, nr 2, s. 77-85Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Study Design Randomized controlled trial. Background Low back pain is a common disorder. Patients with low back pain frequently have aberrant and pain-provocative movement patterns that often are addressed with motor control exercises. Objective To compare the effects of low-load motor control (LMC) exercise and those of a high-load lifting (HLL) exercise. Methods Seventy participants with recurrent low back pain, who were diagnosed with nociceptive mechanical pain as their dominating pain pattern, were randomized to either LMC or HLL exercise treatments. Participants were offered 12 treatment sessions over an 8-week period. All participants were also provided with education regarding pain mechanisms. Methods Participants were assessed prior to and following treatment. The primary outcome measures were activity (the Patient-Specific Functional Scale) and average pain intensity over the last 7 days (visual analog scale). The secondary outcome measure was a physical performance test battery that included 1 strength, 3 endurance, and 7 movement control tests for the lumbopelvic region. Results Both interventions resulted in significant within-group improvements in pain intensity, strength, and endurance. The LMC group showed significantly greater improvement on the Patient-Specific Functional Scale (4.2 points) compared with the HLL group (2.5 points) (P<.001). There were no significant between-group differences in pain intensity (P = .505), strength, and 1 of the 3 endurance tests. However, the LMC group showed an increase (from 2.9 to 5.9) on the movement control test subscale, whereas the HLL group showed no change (from 3.9 to 3.1) (P<.001). Conclusion An LMC intervention may result in superior outcomes in activity, movement control, and muscle endurance compared to an HLL intervention, but not in pain intensity, strength, or endurance.

    Do we see the same movement impairments?: the inter-rater reliability of movement tests for experienced and novice physiotherapists2014Ingår i: European Journal of Physiotherapy, ISSN 2167-9169, E-ISSN 2167-9177, Vol. 16, nr 16, s. 173-182, artikel-id 3Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Study design: Inter-rater reliability study. Background: Physiotherapists (PTs) use clinical tests including movement tests to identify faulty movement patterns. Aims: To investigate the inter-rater-reliability of active movement tests in the cervical spine, shoulder joint and scapulo-thoracic joint, and to describe the reasons for judgment of a positive test. Methodology: Four PTs, two experienced and two recently educated (novice), rated performance of five movement tests for 36 participants. Twenty-one of the participants were patients under treatment because of neck and/or shoulder problems, while 15 participants declared no problem from this region of the body. All tests were video recorded and the ratings were done by observing the video recordings. First, the PTs judged the tests as negative (the movement being ideally performed) or positive (the movement not being ideally performed). Then, the PTs described why the movements that they judged positive were not being ideally performed, using a predefined protocol, which represented different movement quality aspects. The inter-rater reliability was calculated for each test using Kappa statistics between the two experienced and the two novice PTs, respectively, and between each of the experienced and each of the novice PTs. Major findings: The experienced PTs had a higher inter-rater reliability than the novice PTs. The reasons for considering a movement test being positive differed highly between the (novice) PTs. Principal conclusion: This study supports previous studies concluding that the observation of active movement tests is reliable when assessed by experienced PTs. Novice PTs might benefit from further supervision.

    Acuity of goal-directed arm movements and movement control: evaluation of differences between patients with persistent neck/shoulder pain and healthy controls2022Ingår i: European Journal of Physiotherapy, ISSN 2167-9169, E-ISSN 2167-9177, Vol. 24, nr 1, s. 47-55Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The main aim was to examine whether patients with persistent upper quadrant pain have higher end-point variability in goal directed pointing movements than pain-free controls when the pointing task is performed in total darkness and under full vision. An additional aim was to study associations between the magnitude of end-point variability and a clinical movement control test battery and self-rated functioning among patients.

    Methods: Seventeen patients and 17 age- and gender-matched pain-free controls performed a pointing task that evaluated end-point variability of repetitive shoulder movements in horizontal adduction and abduction with full vision, and abduction with no visual information, completed a movement control test battery of neck and shoulder control tests and answered questionnaires.

    Results: Patients had higher end point variability for horizontal abduction when performed with no visual information. For horizontal adduction the variability was higher, but only when it was controlled for movement time. No significant correlations were found between end-point variability and self-rated functioning, nor between end-point variability and neuromuscular control of the glenohumeral joint.

    Conclusions: This study provides preliminary evidence that patients with persistent neck/shoulder pain can partly compensate proprioceptive deficits in goal-directed arm movement when visual feedback is present.

    Användandet av miljöledningssystem och gröna nyckeltal: – en studie av drivkrafter hos mindre företag2007Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats
    Abstract [sv]

    Under de senaste åren har miljömedvetenheten i samhället blivit

    alltmer påtaglig och i synnerhet är det debatten om växthuseffekten som fått mycket stort utrymme i media. Detta har medfört att företagens intressenter börjat ställa allt högre krav på att även företagen ska ta sitt miljöansvar. Ett vanligt sätt att få struktur på miljöarbetet är att implementera ett miljöledningssystem i verksamheten. Företagen väljer ofta att certifiera sig i och med

    införandet av ett miljöledningssystem, vilket även fler och fler av företagens kunder kräver. Idag är det fortfarande i första hand stora företag som miljöredovisar och använder sig av gröna nyckeltal för att visa sin miljöpåverkan för dess intressenter. I mindre företag är inte denna företeelse särskilt vanlig. Med detta som utgångspunkt blev vår problemformulering:

    Vad driver mindre företag att använda miljöledningssystem och gröna nyckeltal och hur bedriver de sitt miljöarbete?

    Vårt syfte med denna uppsats är att kunna ge vägledning om vilka gröna nyckeltal som kan vara relevanta och som mindre företag kan använda sig av i sin redovisning. Vi vill se om det går att identifiera drivkrafterna bakom miljöredovisning och hur intressenterna påverkar

    denna. Vi försöker fånga upp trender inom området och använder företagskoncerner som jämförelsegrund för att visa alternativ och ge exempel på miljöarbete.

    Teorin inleds med en redogörelse för olika drivkrafter som kan finnas bakom miljöredovisning samt en djupare diskussion om gröna nyckeltal. Vidare beskrivs intressentmodellen och legitimitetsteorin samt vad olika intressenter använder miljöredovisning till. Vi valde att

    kombinera en kvantitativ och kvalitativ metod för insamlandet av det empiriska materialet till vår studie. Vi börjar med den kvantitativa

    metoden för att få en överblick samt för att få respondenter till den kvalitativa delen av vår studie.

    I vår analys av det empiriska materialet har vi utgått ifrån vår teoretiska referensram där vi dragit slutsatserna att yttre faktorer och intressenter var viktiga vid initieringen av miljöarbetet och införandet av ett miljöledningssystem hos företagen, men att det senare var de interna fördelarna som värderades högst. Vad det visar är att mindre företag upplever en press utifrån att miljöcertifiera sig men att det i praktiken verkar vara av mindre betydelse vid

    upphandlingar. Det framstår helt klart att implementeringen av ett miljöledningssystem i företaget gör att miljöarbetet blir mer konkret och strukturerat. Vad avser användandet av gröna nyckeltal är det energiförbrukning i olika former som är den dominerande indikatorn,

    däremot verkar det finnas problem att relatera denna på ett enkelt och rättvisande sätt.

    Ambulance Work: Relationships between occupational demands, individual characteristics and health-related outcomes2005Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Although musculoskeletal disorders (MSDs) and other health complaints are an occupational problem for ambulance personnel, there is a lack of knowledge regarding work-related factors associated with MSDs and other health complaints. The overall aim of this thesis was to investigate the relationships between occupational demands, individual characteristics and health-related outcomes among ambulance personnel.

    A random sample of 234 female and 953 male ambulance personnel participated in a national questionnaire survey on work-related factors, and musculoskeletal and other health complaints. Physical demands was associated with activity limitation due to neck-shoulder and low-back complaints among the female personnel. Among the male personnel, physical demands was associated with low-back complaints and activity limitation due to low-back complaints. Psychological demands was significantly associated with neck-shoulder complaints, sleeping problems, headache and stomach symptoms among both female and male ambulance personnel. Worry about work conditions was associated with musculoskeletal disorders and sleeping problems, headache and stomach symptoms.

    A local sample of 26 ambulance personnel was followed during a 24-hour work shift and for the next two work-free days. Subjective stress- and energy levels, and cortisol levels were measured at regular intervals, and heart rate was registered continuously by electrocardiogram (ECG). Autonomic reactivity to standardized tests before (pre-work) and at the end of the work shift (post-work) was also investigated. For the whole group, baseline values of heart rate were higher pre-work than post-work, but autonomic reactivity did not differ. Increased reactivity to the mental test, modest deviation in heart rate variability (HRV) pattern during the late night hours at work and higher morning cortisol values during work than during leisure time were observed in personnel with many health complaints, but not among their co-workers without or with few complaints. Ambulance personnel with many health complaints also reported higher psychological demands and tended to be more worried about work conditions.

    Heart rate (HR), lactate level (LL) and perceived exertion (RPE) were investigated in 17 female and 48 male ambulance personnel during a simulated standardized work task “carry a loaded stretcher”. The ambulance personnel had to carry the loaded stretcher (920 N) up and down three flights of stairs twice. The high physiological strain (HR, LL, RPE) for the male, and near or at maximal strain for the female ambulance personnel, implied the importance to identify what kind of physical capacity is most important for ambulance personnel. Therefore, the explained variance of developed fatigue by tests of cardiorespiratory capacity, muscular strength and endurance, and coordination was investigated. The results showed that VO2max and isometric back endurance were important predictors for development of fatigue when carrying a loaded stretcher.

    The influence of body size on the relationships between maximal strength and functional performance was investigated in a methodological study. The results confirm that the assessment of physical performance could be confounded by the body weight. Therefore, the models for explaining development of fatigue when carrying the loaded stretcher were adjusted for height and weight. Including height in the models significantly increased the explained variance of accumulated lactate among female, but not among male personnel. Lactate levels were higher among short compared to tall female personnel. Weight had no effect on any of the models.

    In conclusion, the national survey showed that self-reported physical demands was a risk factor of having MSDs, and that self-reported psychological demands and worry about work were important risk factors of having MSDs and other health complaints. Stress monitoring of ambulance personnel during work and leisure time showed that physiological and subjective stress markers did not show any differences between the 24-hour ambulance work shift and leisure time afterwards. However, ambulance personnel with many health complaints had certain physiological changes during the work shift in comparison with the next two work-free days. The physiological and subjective responses during carrying a loaded stretcher, especially among the female ambulance personnel, showed that female and male ambulance personnel could be exposed to internal exposures at different levels when performing the same work task. A better understanding of the relationships between occupational demands and health-related outcomes require further studies on age- and gender matched groups in long-term perspective studies.

    Relationships between work-related factors and disorders in the neck-shoulder and low-back region among female and male ambulance personnel.2005Ingår i: Journal of Occupational Health, ISSN 1341-9145, E-ISSN 1348-9585, Vol. 47, nr 6, s. 481-9Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This cross-sectional study on a random sample of 1,500 ambulance personnel investigated the relationships between self-reported work-related physical and psychosocial factors, worry about work conditions, and musculoskeletal disorders among female and male ambulance personnel. Three different outcomes, complaints, activity limitation, and sick leave, for the neck-shoulder and low-back region, respectively, were chosen. Among the female personnel, physical demands was significantly associated with activity limitation in the neck-shoulder (OR 4.13) and low-back region (OR 2.17), and psychological demands with neck-shoulder (OR 2.37) and low-back (OR 2.28) complaints. Among the male personnel, physical demands was significantly associated with low-back complaints (OR 1.41) and activity limitation (OR 1.62). Psychological demands and lack of social support were significantly associated with neck-shoulder complaints (OR 1.86 and OR 1.58, respectively) and activity limitation (OR 3.46 and OR 1.71) as well as activity limitation due to low-back complaints (OR 2.22 and OR 1.63). Worry about work conditions was independently associated with activity limitation due to low-back complaints among the female (OR 5.28), and to both neck-shoulder and low-back complaints (OR 1.79 and OR 2.04, respectively) and activity limitation (OR 2.32 and OR 1.95) among the male personnel. In conclusion, the association patterns between physical and psychological demands and MSDs suggest opportunities for intervention.

    Variability of lumbar spinal alignment among power- and weightlifters during the deadlift and barbell back squat2022Ingår i: Sports Biomechanics, ISSN 1476-3141, E-ISSN 1752-6116, Vol. 21, nr 6, s. 707-717Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aims of the study were to evaluate the relative and absolute variability of upper (T11-L2) and lower (L2-S2) lumbar spinal alignment in power- and weightlifters during the deadlift and back squat exercises, and to compare this alignment between the two lifting groups. Twenty-four competitive powerlifters (n = 14) and weightlifters (n = 10) performed three repetitions of the deadlift and the back squat exercises using a load equivalent to 70% of their respective one-repetition maximum. The main outcome measures were the three-dimensional lumbar spinal alignment for start position, minimum and maximum angle of their spinal alignment, and range of motion measured using inertial measurement units. Relative intra-trial reliability was calculated using the two-way random model intraclass correlation coefficient (ICC) and absolute reliability with minimal detectable change (MDC). The ICC ranged between 0.69 and 0.99 and the MDC between 1 degrees-8 degrees for the deadlift. Corresponding figures for the squat were 0.78-0.99 and 1 degrees-6 degrees. In all participants during both exercises, spinal adjustments were made in both thoracolumbar and lumbopelvic areas in all three dimensions. In conclusion, when performing three repetitions of the deadlift and the squat, lumbar spinal alignment of the lifters did not change much between repetitions and did not differ significantly between power- and weightlifters.

    A descriptive analysis of functional impairments and patho-anatomical findings in eight powerlifters2020Ingår i: Journal of Sports Medicine and Physical Fitness, ISSN 0022-4707, E-ISSN 1827-1928, Vol. 60, nr 4, s. 582-593Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Low back pain (LBP) is a common pain problem in powerlifters. There is a lack of evidence to guide powerlifters and health-care professionals in understanding the role of powerlifting in the development of LBP and treatment of injuries in powerlifters. This study aimed to describe functional impairments and patho-anatomical findings in eight powerlifters with and without LBP. METHODS: First, four powerlifters with LBP were recruited. Each powerlifter was then matched with a pain-free lifter (Control) by age, Body Mass Index and competition weight class. They all performed physical performance tests and were examined with magnetic resonance imaging. Four weeks prior to the examination the powerlifters also recorded training load. Powerlifters with LBP were also examined by a physiotherapist in order to define their pain and impairments. RESULTS: The four male powerlifters with LBP had a nociceptive pain associated with non-ideal squatting technique, higher flexibility in their lumbar spine than in their hips and patho-anatomical findings such as degenerated discs (four), spondylolysis (one) and spinal stenosis (one). However, the controls also showed similar functional impairments and patho-anatomical findings. CONCLUSIONS: Powerlifters with and without LBP show similar functional impairments and patho-anatomical findings. However, powerlifters' LBP seems associated with pain during movement and loading of the lumbar spine. The association and causation between specific functional impairments, patho-anatomical findings and LBP in powerlifters has to be further investigated in studies including more participants.

    Muscle strength assessment from functional performance tests: role of body size2003Ingår i: Journal of Strength and Conditioning Research, ISSN 1064-8011, E-ISSN 1533-4287, Vol. 17, nr 4, s. 664-670Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of the study was to test the hypothesis that the body size plays an important role in assessment of muscle ability to exert force by standard functional performance tests. Twenty-one male students were tested on maximal isometric lift, one leg rising, vertical jump, and box lift tests, and the maximal isokinetic strength of hip and knee extensors was also recorded. When indices of the 4 functional performance tests were related to the strength of each of the 2 leg extensor muscle groups, only maximal isometric lift demonstrated positive correlation with knee extensors strength. When muscle strength was corrected for body mass, however, the aforementioned relationship became insignificant, but the 1 leg rising performance demonstrated a positive relationship with knee extensor strength. In addition, maximal isometric lift and 1 leg rising test performance provided positive and negative correlation, respectively, with body mass. The obtained findings were in line with the effects of scale applied on the tested performance. We generally conclude that the assessment of muscle capability to exert force based on some standard functional performance tests could be confounded by the body size effect.

    The impact of object size and precision demands on fatigue during computer mouse use2011Ingår i: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 13, nr 3, s. 118-127Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Prolonged computer use, especially if fatigue ensues, is associated with visual and musculoskeletal symptoms. The aim was to determine the time-course of perceived fatigue in the wrist, forearm, shoulder and eyes during a 60-min mouse task (painting rectangles), and whether object size and/or mouse use demands were of infl uence. Also, we investigated performance (number of rectangles painted), and whether perceived fatigue was paralleled by local muscle fatigue or tissue oxygenation.

    Ten women performed the task for three conditions (crossover design). At condition 1, rectangles were 45 25 mm, square paint cursor size 1.3 1.3 mm, and mouse – pointer movement ratio 1:26. At condition 2, the same cursor size and mouse – pointer movement ratio was used, but rectangles were smaller. At condition 3, the smaller rectangles were used, but the cursor size was also smaller and mouse – pointer movement ratio was 1:8. The results showed increased self-reported fatigue over time, with the observed increase greater for the eyes, but no change in physiological responses. Condition 2 resulted in higher performance and increased eye fatigue. Perceived fatigue in the muscles or physiological responses did not differ between conditions. In conclusion, computer work tasks imposing high visual and motor demands, and with high performance, seemed to have an infl uence on eye fatigue.

    Physical Activity Might Be of Greater Importance for Good Spinal Control Than If You Have Had Pain or Not: A Longitudinal Study2015Ingår i: Spine, ISSN 0362-2436, E-ISSN 1528-1159, Vol. 40, nr 24, s. 1926-1933Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    STUDY DESIGN: Longitudinal design. A cohort followed in 3 waves of data collection.

    OBJECTIVE: The aim of the study was to describe the relationships between the performance of 2 tests of spinal control at the age of 52 years and low back pain, physical activity level, and fitness earlier in life, as well as to describe the cross-sectional relationships between these measures.

    SUMMARY OF BACKGROUND DATA: Altered spinal control has been linked to pain; however, other stimuli may also lead to inability to control the movements of the spine.

    METHODS: Participants answered questions about physical activity and low back pain, and performed physical fitness tests at the age of 16, 34, and 52 years. The fitness test battery included tests of endurance in the back and abdominal muscles, a submaximal bicycle ergometer test to estimate maximal oxygen uptake, and measurements of hip flexion, thoracic spine flexibility, and anthropometrics. Two tests were aggregated to a physical fitness index. At the age of 52, also 2 tests of spinal control, the standing Waiter's bow (WB) and the supine double leg lower (LL) were performed.

    RESULTS: Logistic regression analyses showed that higher back muscle endurance at the age of 34 years could positively predict WB performance at 52 years and higher physical fitness at the age of 34 could positively predict LL performance at 52 years. Regarding cross-sectional relationships, an inability to perform the WB correctly was associated with lower physical fitness, flexibility and physical activity, and larger waist circumference. An inability to correctly perform the LL was associated with lower physical fitness. One-year prevalence of pain was not significantly associated with WB or LL test performance.

    CONCLUSION: An active life resulting in higher physical fitness is related to better spinal control in middle-aged men and women. This further strengthens the importance of physical activity throughout the life span.

    LEVEL OF EVIDENCE: 3.

    The Swedish physical activity and fitness cohort born in 1958 - dropout analysis and overview at 36-year follow-up2017Ingår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 27, nr 4, s. 418-429Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The main aim of the Swedish physical activity and fitness cohort study (SPAF-1958) was to describe physical fitness, physical activity, health, and lifestyle across part of the lifespan, and to assess the influences on these factors from the environment, personal factors, and genetics. There is inevitable dropout from longitudinal studies, and it may be systematic. The aim of this first paper of the second follow-up of SPAF-1958 was to provide a dropout analysis to consider to what extent the participants, at 52 years of age, remain a representative sample of the original adolescent study population. Additional aims were to provide an overview of the study protocol and the ongoing study population. Ongoing study participants in SPAF born in 1958 were, at the second follow-up at the age of 52, still representative of the study cohort in terms of sex, adolescent geographical area, upper secondary school program, adolescent body composition, muscular strength, and muscular endurance. However, a higher physical activity and, among women, a higher aerobic capacity in adolescence decreased the risk for dropout. It is important when interpreting results from longitudinal studies to adjust for the systematic dropout that could bias the conclusions drawn from the results.

    Correspondence between physical self-concept and participation in, and fitness change after, bi-weekly body conditioning classes in sedentary women2017Ingår i: Journal of Strength and Conditioning Research, ISSN 1064-8011, E-ISSN 1533-4287, Vol. 31, nr 2, s. 451-461Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aims of the study were (1) to investigate the effects of participation in low impact body conditioning classes on physical fitness in sedentary women at different ages and (2) to examine the correspondence between physical self-concept and participation in, and fitness change after, the participation. Ninety-two sedentary women (mean age 44.2 years) participated in 11-weeks of bi-weekly classes that included cardiovascular, strength, core, endurance and mobility exercises, all performed in synchrony with music. Cardiorespiratory fitness, maximal lifting strength, mobility and balance tests were performed pre- and post the exercise period and the short-form Physical Self-Description Questionnaire (PSDQ-S) was completed. Zero-order Spearman correlation analyses showed that women who rated the PSDQ-S dimension Sport competence higher participated in a larger number of sessions (rs=0.24, p=0.040). At post-tests, all participants had increased their balance, the participants aged 20-34 years had increased their lifting strength, and the participants aged 35-65 years had increased their cardiorespiratory fitness and mobility. Most PSDQ-S dimensions did not affect performance change, but the perception of being physically active was related to increased cardiovascular fitness. We conclude that women with a sedentary lifestyle who wish to increase their physical capacity benefit from music exercise and that inquiries about perceived sport competence and physical activity can improve recommendations made by strength and conditioning professionals.
