    Evaluating the performance of academic departments: an analysis of research-related output efficiency2012In: Research Evaluation, ISSN 0958-2029, Vol. 21, no 1, p. 2-14Article in journal (Refereed)
    Abstract [en]

    In this article we investigated whether academic departments do experience a trade-off among different research outputs. More specifically, we define four types of academic research outputs: quantity (publications); quality (citation indexes); research funds obtained through research grants; and applied research funds obtained through external orders. Subsequently, we define a department's performance through the concept of efficiency, namely the ability to maximize academic research output given an amount of inputs (facilities and human resources). Using Data Envelopment Analysis (DEA), we measure efficiency for 69 academic departments (focused on scientific subjects) located in the Lombardy Region (Italy), benefiting from a unique data set containing detailed information on research inputs and outputs. The empirical analysis shows that efficiency rankings change significantly when considering different research-related outputs and thus it highlights different research strategies among the academic departments. These different strategies emerge also considering jointly all four types of outputs: the academic departments focus on different outputs in order to obtain the highest overall efficiency scores. In the last section, policy and managerial implications have been discussed.

    How does the alignment of IT to business strategy affect the organisation of the IT function?2008Student thesis
    Abstract [en]

    Date: 2008-06-04

    Purpose: The primary goal of this research is to describe the IT function and examine how its alignment to an organisations strategy affects the way it is organised.

    Method: The chosen method was a purely theoretical examination with the use of the case study of Windham International as primary resource and secondary resources such as book and literature review used for the thesis.

    Research Questions: How does the alignment of IT to business strategy affect the organisation of the IT function?

    Conclusion: One of the findings was that a few researchers seem to suggest that the centralized mode of organising IT was symbolic of the past, while outsourcing and decentralization are the modern approach to organising IT. Wyndham International shows the opposite, after the introduction of the CIO in 2002, centralization was the chosen mode of organisation because that was what would best fit the new strategic approach of the organisation. Insourcing rather than outsourcing proved to be a winning formula.

    Sjuksköterskors upplevelser av att vårda palliativt: En litteraturstudie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Patients who receive palliative care experience that they lose their independence through the disease and are frustrated that their body is not functioning as before. They also experience that their situation make them change their attitudes towards life. Several patients appreciate when healthcare professionals show genuine interest and the same patients have confidence in the healthcare system. Some patients experience that the healthcare professionals have no time and that their knowledge regarding their psychosocial problems is inadequate. Aim: The purpose is to describe nurses experience of nursing in palliative care. Method: Qualitative literature study with descriptive synthesis. Ten qualitative articles have been analyzed and is presented in the result. Results: After analysis, two themes were disclosed; Becoming enriched and Being challenged who described nurse’s experiences presented under five subthemes. Conclusion: Nurses perceived, among other things, that they were strengthened as a person and that they learned to re-prioritize and appreciate life. They also experienced grief over the fate of patients and it was common to take work home. Several of the nurses perceived that doctors did not give them support, others felt that their lack of experience contributed to the care worsening.

    Ergonomisk kartläggning av internt logistikflöde - Med förbättringsförslag: En fallstudie genomförd på ett företag2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study is firstly to identify risks of ergonomic strain in a future internal logistics flow and secondly propose how to avoid these risks by applying LEAN methodology and a new logistics solution. In order to identify causes for problems and to find improvement opportunities the following issues have been addressed:

    1)    What tasks in the studied logistics flow lead to risks of ergonomic strain?

    2)    How can the studied company implement the LEAN methodology to improve ergonomics in the material handling?

    3)    How can a new general and more ergonomic logistic solution for material handling look like for the studied company?

    Method: The study has been conducted based on a case at an industrial company. Data has been collected through interviews and observations at the company, visits at two other industries and through a literature survey. To identify and assess various ergonomic risks, the RAMP tool has been applied.

    Study result: The study resulted in an ergonomic survey for a selected internal logistics flow with suggestions on how to improve ergonomics in the studied company´s material handling. The ergonomic survey showed that several work tasks cause an increased risk for the operators to develop strain injuries and therefore improvements are required. Heavy lifting, pulling and sliding work pieces and incorrect working positions were shown to have the most adverse impact on good ergonomics. To reduce these risks - without major changes to the current factory layout and existing workflow - work rotation, various tools/aids and modifications of technical equip-ment can be implemented. Proposals are presented on how a new and more ergonomic material handling solution can be achieved at the studied company through the introduction of a pickup station and a “supermarket”. A suggested framework is also presented for how the company can use LEAN methodology in order to achieve better ergonomics in the material handling process.

    Conclusion: The ergonomic survey indicated that improvements are required in order not to risk strain injuries for the operators. Suggestions have been made for how the ergonomic situation can be improved.

    Recommendations: The studied company is recommended to take measures with respect to the ergonomic risks identified. Before the proposed improvements can be introduced, studies are required to evaluate the improvement proposals from other than ergonomic aspects as well as performing a RAMP analysis. The studied company is also recommended to investigate the possibility of introducing the proposed LEAN framework.

    Foveal function in children treated for amblyopia.2010In: Acta ophthalmologica, ISSN 1755-3768, Vol. 88, no 2, p. 222-226Article in journal (Refereed)
    Abstract [en]

    PURPOSE: This study aimed to evaluate foveal function, using three different methods, in children treated for monocular amblyopia. METHODS: A sample of 24 otherwise healthy children with treated amblyopia and an age-matched control group of 25 healthy children were examined for best corrected visual acuity (BCVA) using a standard decimal (KM) chart and the computerized TriVA method at 50% and 10% contrasts. Foveal function was also measured with the rarebit fovea test (RFT), which is included in the rarebit perimetry program package. This test uses very small and bright dots against a dark background. The result is expressed as mean hit rate (MHR). RESULTS: Amblyopic eyes showed significantly lower BCVA when evaluated with the KM chart and with the TriVA test at different contrast levels, compared with both fellow eyes and control eyes. No statistically significant difference between amblyopic and fellow eyes was found when foveal function was evaluated with the RFT (median MHRs 91.5% and 94.5%, respectively), although results for both amblyopic and fellow eyes were statistically lower than those of the control group (median MHR 97%) (p = 0.001 and p = 0.046, respectively). This might indicate that the RFT provides different information about foveal function than conventional VA tests. CONCLUSIONS: The findings in the current study accord with those of other studies reporting abnormalities in the fellow eyes of previously treated amblyopic patients. These findings may reflect a general disturbance in the visual system rather than a monocular adaptation to refractive error or ocular motor disturbance.

    Så styrs Mälarenergi med hjälp av Balanserat Styrkort2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Title:   Controlling Mälarenergi by Balanced Scorecard 

    Seminar date:  2009-01-16 

    Institution:   School of Sustainable Development of Society and Technology 

    Course:   Bachelor thesis 15hp 

    Authors:   Camilla Nilsson, Amanda Agestav 

    Advisor:   Ulla Pettersson 

    The main issues:                What does Mälarenergi's Balanced Scorecard look like? Which Balanced Scorecard perspectives are important to Mälarenergi? Is Balanced Scorecard a purposeful control model in order for the group management to fulfil the aims of the owners' directives? 

    Purpose:                            The purpose is to find out how the group management at Mälarenergi works with Balanced Scorecard. Is Balanced Scorecard a purposeful tool for the group management to fulfill the aims of the owners' directives? 

    Method:                             This study is based on a qualitative research method in the form of interviews. We have interviewed one respondent. Secondary data have been produced by literature search. 

    Conclusion:                       Mälarenergi uses Balanced Scorecard exclusively at a group management level. The strategic work at the business areas' different division levels takes place aided by a business development model. We believe that Balanced Scorecard is a purposeful tool to use in order to clarify a company's strategy work and reach the goals in the owners' directives. However, Mälarenergi needs to complement the Balanced Scorecard with another model, since the business areas are so different from each other. In doing so, however, there is a risk that not all employees will be involved in the Balanced Scorecard, but that this will become an exclusive tool to the group management. We believe that there is no clear connection between the Balanced Scorecard work done in the group management and the work within the different business areas with their various focus areas.

    A systematic Mapping study of ADAS and Autonomous Driving2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Nowadays, autonomous driving revolution is getting closer to reality. To achieve the Autonomous driving the first step is to develop the Advanced Driver Assistance System (ADAS). Driver-assistance systems are one of the fastest-growing segments in automotive electronics since already there are many forms of ADAS available. To investigate state of art of development of ADAS towards Autonomous Driving, we develop Systematic Mapping Study (SMS). SMS methodology is used to collect, classify, and analyze the relevant publications. A classification is introduced based on the developments carried out in ADAS towards Autonomous driving. According to SMS methodology, we identified 894 relevant publications about ADAS and its developmental journey toward Autonomous Driving completed from 2012 to 2016. We classify the area of our research under three classifications: technical classifications, research types and research contributions. The related publications are classified under thirty-three technical classifications. This thesis sheds light on a better understanding of the achievements and shortcomings in this area. By evaluating collected results, we answer our seven research questions. The result specifies that most of the publications belong to the Models and Solution Proposal from the research type and contribution. The least number of the publications belong to the Automated…Autonomous driving from the technical classification which indicated the lack of publications in this area.

    E-budgivning: Vägen in på marknaden2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Frågeställning: Finns utrymmet för en ny verksamhet som E-budgivning på den svenska bostadsmarknaden? Fungerar företagets affärsidé eller är marknaden mättad?                    Kan E-budgivning eventuellt utmana andra aktörer och få en etablerad plats på svenska bostadsmarknaden?

    Syfte: Syftet med studien är att undersöka och analysera E-budgivnings chanser på marknaden för en eventuell framgång.

    Metod: En kvalitativ intervju med en representant från E-budgivning samt en kvantitativ enkätundersökning bidrog till primärdata. De sekundärdata som samlats är litteratur från böcker, tidsskrifter samt Internet.

    Allt fler företag väljer att satsa på Internetbaserade marknaden. Företag bemöter en hård konkurrens på bostadsmarknaden och slåss om konsumenterna som blivit allt mer prismedvetna mycket på grund av Internets framfart.

    Studien riktar sig till ett nystartat företag vid namn E-budgivning som är intresserade av att etablera sig på svenska bostadsmarknaden. Under tidigare år har valet av mäklare varit en självklarhet vid försäljning och köp av en bostad. Idag är inte valet lika självklart eftersom flera aktörer trätt in på marknaden och där urvalet av en rad olika alternativ finns att tillgå.

    Ett intresse samt funderingar uppkom om hur marknaden kommer se ut i framtiden och vilka chanser och möjligheter E-budgivning har. Genom teorier och empirisk data från undersökningar genom arbetets gång har konstanterandet gjorts att E-budgivnings etableringsmöjligheter ligger rätt i tiden. En stor faktor till resultatet är mycket på grund av teknologiska utvecklingen i kombination med företagets nischade affärsidé.

    Däremot passar den långt ifrån alla konsumenter då alla har skilda åsikter och behov vilket även historien bevisar. Studien visar att E-budgivning inte har en chans att hota stora aktörer på allvar, däremot har företaget goda möjligheter att få marknadsandelar med rätt marknadsföring.

    Practical 3-D beam pattern based channel modeling for multi-polarized massive MIMO systems2018In: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 18, no 4, article id 1186Article in journal (Refereed)
    Abstract [en]

    In this paper, a practical non-stationary three-dimensional (3-D) channel models for massive multiple-input multiple-output (MIMO) systems, considering beam patterns for different antenna elements, is proposed. The beam patterns using dipole antenna elements with different phase excitation toward the different direction of travels (DoTs) contributes various correlation weights for rays related towards/from the cluster, thus providing different elevation angle of arrivals (EAoAs) and elevation angle of departures (EAoDs) for each antenna element. These include the movements of the user that makes our channel to be a non-stationary model of clusters at the receiver (RX) on both the time and array axes. In addition, their impacts on 3-D massive MIMO channels are investigated via statistical properties including received spatial correlation. Additionally, the impact of elevation/azimuth angles of arrival on received spatial correlation is discussed. Furthermore, experimental validation of the proposed 3-D channel models on azimuth and elevation angles of the polarized antenna are specifically evaluated and compared through simulations. The proposed 3-D generic models are verified using relevant measurement data.

    En studie om hur invandrarkvinnor upplever integrationsprocessen i Sverige2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna undersökning är att fördjupa förståelse för invandrarkvinnors upplevelser av integrationen i Sverige. Undersökningen syftar på enbart invandrarkvinnor som kommer till Sverige genom äktenskapsmigration. Detta är en kvalitativ undersökning som har genomförts med hjälp av nio intervjuer med invandrarkvinnor som har gift sig med svenskfödda män och flyttat till Sverige. Vi har valt att använda Grundad teori och har kommit fram till olika faser som innefattar faktorer som kvinnorna upplever vara viktiga för integrationen. Genom att analysera de olika faserna kom vi fram till vår kärnkategori som är arbete. Resultatet visade att arbete är kärnan i integrationen och en viktig och avgörande faktor för en lyckad integration. Teoretiska paralleller dras till Antonovskys teori om Känsla av sammanhang (KASAM) för att klargöra upplevelsen av integrationsprocessen.

    Piratkopiering i Sverige: Hur fildelare själva reflekterar över sina handlingar2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här uppsatsen behandlar ämnet olaglig fildelning på internet. Intervjuer med fem svenska fildelare ligger till grund för en kvalitativ analys av deras egna handlingar. Analysen kretsar kring fem grundläggande teman som syftar till att förmedla en bild av individernas egen bild av fildelning och moraliska dilemman som kan uppstå vid denna handling. Teorin som har används beskriver främst handlingsramarna och samhället som fildelarna kan tänkas befinna sig i. Kopplingar görs mellan individernas handlingar och den övergripande samhällsteorin för att påvisa om de stämmer överränns. Olaglig fildelning är ett utbrett fenomen i Sverige. De fem fildelare som ingick i analysen verkar både ha förståelse för att fildelning är ett så utbrett fenomen, samtidigt som de i stor utsträckning känner att det behövs en lag som reglerar fenomenet. Skivbolagen målas upp som de stora och rika bovarna i frågan.

    Resource Management and Control in Virtualized SDN Networks2018In: CSI International Symposium on Real-Time and Embedded Systems and Technologies REST'18, 2018, p. 47-53Conference paper (Refereed)
    Abstract [en]

    Software defined networking and network virtual-ization are widely considered promising techniques for reducing the complexity of network management in many contexts that require high Quality of Service (QoS) and the support for heterogeneous architectures. In this paper we address a network architecture, here called a virtualized SDN network, that combines the benefits of SDN and virtualization. To cope with the demand for efficiently sharing a platform among several services, here a resource management mechanism to reserve and control network resources among various services in the virtualized SDN networks is proposed. The mechanism is implemented on an SDN controller and a set of experiments show the effectiveness of the proposed approach.

    Bemötande i förskolan: möten som formar2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsens syfte är att undersöka hur pojkar och flickor bemöts av pedagoger på en förskola. Datainsamlingen har gjorts genom observationer av hur bemötandet sker vid olika situationer på tre stora avdelningar. Forskningsansatsen är kvalitativ. Datainsamlingen har även genomförts med hjälp av intervjuer med förskollärare. Undersökningen visar på en viss skillnad i hur förskollärarna bemöter barnet olika beroende på vilket kön barnet har. Förskollärarna var ofta inte medvetna om att de gör en skillnad i hur de bemöter barnen. Vidare är de översens om att jämställdhet är ett viktigt perspektiv i det pedagogiska arbetet. De anser att de måste bli medvetna om sina förutfattade meningar och sitt aggerande utifrån dessa. Det är först när man får kunskap och förståelse för genusbegreppet som det går att förändra de stereotypa könsrollerna.

    Gruppkonstellationer i förskolan: En undersökning om förskollärares uppfattningar2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna undersökning är att ta reda på förskollärares uppfattningar om hur de formar gruppkonstellationer i förskolan. Utifrån forskningsfrågorna syftar undersökningen på att få svar på vilka varierade uppfattningar förskollärare har om didaktiska val som tillämpas och vilket perspektiv som beaktas i formandet av gruppkonstellationer. Utifrån en kvalitativ metod med en fenomenografisk ansats har åtta förskollärare från olika förskolor intervjuats. Resultatet visar att förskollärarna kunde koppla flera aspekter i förhållandet till att forma gruppkonstellationer i förskolan. Aspekter förskollärarna har uppfattningar om och som är av betydelse för att skapa främjande gruppkonstellationer har dels att göra med vilka didaktiska val som tillämpas, förutsättningar och förhållningssätt. Uppfattningar visar på vikten av ett flexibelt förhållningssätt utifrån ett barn- och vuxenperspektiv och att forma gruppkonstellationer utifrån barns behov och förutsättningar.

    "Bloody hög turkmusik kl 4 på morgonen runt malmvägen inte OK fy inget annat område skulle acceptera detta!": Om innehåll, språk och funktion i statusuppdateringar på Facebook2012Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Arbetet är en kvalitativ studie av det sociala internetnätverket Facebooks statusuppdateringar – de textstycken där en facebookanvändare skriftledes kan meddela sig till sina kontakter i det gemensamma nyhetsflödet. Studien undersöker huruvida det finns återkommande kategorier av statusuppdateringar och vilka dessa i så fall är, vilket språk som används i uppdateringarna samt hur användarens syfte med statusuppdateringen synliggörs. Materialet utgörs av fyra informanters statusuppdateringar under en sammanhängande begränsad tidsperiod. Studien visar att det finns återkommande kategorier av innehållsteman samt återkommande språkliga drag i statusuppdateringarna. Språket som används i statusuppdateringar på Facebook är mångfacetterat – stundom stavningsmässigt och grammatiskt korrekt, stundom talspråkligt och normutmanande och varierar givetvis informanterna emellan. Vissa informanter uttrycker sig mycket kommunikationsmedvetet medan andra har ett mer prosaiskt betonat språk. De olika kategorierna och kombinationer av dessa nyttjas för att nå olika syften. Varje kategori kan ses som ett redskap för att försätta läsaren i en viss sinnesstämning alternativt dela med sig av sin egen. Kreativitet och lekfullhet med normer används exempelvis som ett verktyg för att skapa en utstickande statusuppdatering då detta är syftet.

    Författare ur livets egen skola: En litteraturstudie i hur den klassiska svenska arbetarlitteraturen behandlas i gymnasieskolans läroböcker2012Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Arbetet är en kvalitativ litteraturstudie som undersöker hur den klassiska svenska arbetarlitteraturen behandlas i gymnasieskolans läroböcker. Materialet utgörs av textavsnitten om arbetarförfattare i två olika läroböcker som används i litteraturundervisningen på gymnasiet varav den ena textnivå- och stilmässigt verkar rikta sig till elever som befinner sig på en något högre kunskapsmässig nivå. Studien visar  att de båda läroböckerna har varierande sätt att framställa genren arbetarlitteratur och särskilt särskiljande är det språk och den pedagogiska stil läroboksförfattarna använder. Flera gemensamma beröringspunkter förekommer, såsom exempelvis den rika användningen av citat vilket verkar vara ett pedagogiskt grepp som syftar till att fånga kontentan av ett visst arbetarverk eller författarskap. Författarurvalet är likartat i de båda läroböckerna, och högst sannolikt inspirerat av den rådande kanon som presenteras i vedertagna litteraturhistorieskrivningar vilka utgörs av bl a läroböcker för högre eftergymnasiala studier. Läroboksförfattarna har, vad gäller författarurvalet, gett tydligt företräde åt genrens giganter. Fokus på det enskilda verket respektive arbetarförfattaren själv varierar mellan de två läroböckerna. Varken den enskilde arbetarförfattarens stil eller litteraturhistoriska sammanhang diskuteras i någon stor utsträckning i någon av läroböckerna. Som nämnt är det språkliga och stilistiska vad som främst skiljer de två analyserade läroböckerna åt. Den lärobok vars målgrupp verkar vara elever på ett högre kunskapsplan ger eleven åtskilliga nivåer att läsa sig igenom; fler detaljer och fler till reflektion uppmanande resonemang medan den andra läroboken förblir vid textens översta ytskikt. Denna visar främst i sitt enkla, rättframma språk, vilket inte tycks utmana en genomsnittligt läsbegåvad elev nämnvärt; syftet med lärobokstexten är att under okomplicerade förhållanden förse eleven med fakta.  Den mer teoretiska läroboken uppmanar genom den fyllighet som karaktäriserar texten, dess kunskapsutmanande vokabulär samt genom sin diskuterande, analyserande ton eleven till fördjupat tillägnande av arbetarlitteratur

    Factors associated with work ability in patients with chronic whiplash-associated disorder grade II-III: A cross-sectional analysis2015In: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 47, no 6, p. 546-551Article in journal (Refereed)
    Abstract [en]

    Objective: To investigate the factors related to self-perceived work ability in patients with chronic whiplash-associated disorder grades II-III. Design: Cross-sectional analysis. Patients: A total of 166 working age patients with chronic whiplash-associated disorder. Methods: A comprehensive survey collected data on work ability (using the Work Ability Index); demographic, psychosocial, personal, work- and condition-related factors. Forward, stepwise regression modelling was used to assess the factors related to work ability. Results: The proportion of patients in each work ability category were as follows: poor (12.7%); moderate (39.8%); good (38.5%); excellent (9%). Seven factors explained 65% (adjusted R2= 0.65, p < 0.01) of the variance in work ability. In descending order of strength of association, these factors are: greater neck disability due to pain; reduced self-rated health status and health-related quality of life; increased frequency of concentration problems; poor workplace satisfaction; lower self-efficacy for performing daily tasks; and greater work-related stress. Conclusion: Condition-specific and psychosocial factors are associated with self-perceived work ability of individuals with chronic whiplash-associated disorder.

    Anorexia Nervosa: Kvinnors upplevelse av sjukdomsförloppet2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    AN är en sjukdom som drabbar många unga kvinnor idag. Sjukdomen innebär ett långt förlopp och karakteriseras av biologiska, psykiska och sociala besvär. Syftet med studien är att lyfta fram före detta AN  patienters upplevelse av sjukdomsförloppet och de bidragande faktorerna till återhämtningen. 11 semistrukturerade intervjuer genomfördes och analyserades och resultatet tyder på att deltagarna delar likande livshistorier om både insjuknandet och faktorer till återhämtning. Delar av resultatet tyder på att deltagarna hittat motivation i relationer för bli fri från ätstörningen. Vidare forskningen inom detta område borde belysa och fördjupas i den attityd mot att sjukdomen är kronisk och även undersöka individers upplevda likgiltighet mot att kunna leva ett liv helt utan AN, då resonemanget att det inte går att bli helt återställd ofta uttrycks.

    Analys av godssorteringen på DHL Freight AB: En fallstudie om logistik2011Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Det här examensarbetet har genomförts på DHL Freight AB i Eskilstuna som transporterar gods över hela Sverige. Där målsättningen varit att analysera den nuvarande sorteringsprocessen, identifiera bristerna runt sorteringsprocesserna och därefter presentera eventuella förbättringsförlag.

    De metoder som har använts för att utföra examensarbetet är följande. Resultatet grundar sig på den information som har införskaffats via observationer och intervjuer med personalen som är delaktiga i sorteringsprocessen samt olika litteraturstudier.

    De mest tongivande teorierna som examensarbetet utgått från och som författaren har genomgående haft i åtanke är logistik, distribution, Lean Produktion, kvalitet och processer.

    Analysen som utfördes resulterade i att ett antal brister som finns i sorteringsprocessen som kunde identifieras. De här bristerna bidrog till att komplikationer uppstod vid sorteringen av gods på DHL Freight AB. Några exempel på brister som identifierats är att efter godset har hanterats sker inte någon kvalitetssäkring innan godset lämnar terminalen. Dessutom är de resurser som finns idag inte så uppdaterade arbetssätten har inte ändrats eller förbättras på länge. Som till exempel förenkling av kodboken och en mycket tydligare platsning i zonerna så att inte godset ställs på fel plats. Ytterligare brister som kunde identifieras var att den mänskliga faktorn som spelar en stor roll i sorteringen av gods. Att man inte är tillräckligt uppmärksam när man kodar, hanterar eller platsar godset. Man är inte motiverad eller engagerad till att godset ska gå rätt till 100 procent eller så handlar det om att metoderna de använder för att hantera godset är otillräckliga.

    De förbättringsförslag som presenteras i den här rapporten innefattar förändringar som kan leda till att sorteringsprocessen på DHL Freight AB, men även i hela försörjningskedjan, blir mer kontrollerad och exakt jämfört med dagens situation. Förutom en bättre sorterings statistik som uppstår på DHL Freight AB vid sortering av gods, kan dessa förändringar även bidra till kostnadsbesparingar i form av energikostnader och personalkostnader hos DHL Freight i Eskilstuna

    Mobila verksamhetslokaler: En studie om marknadsvärderingar2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Mobile buildings offer a flexible supply of buildings as an alternative to permanent expansion or while the existing facilities being renovated or rebuilt. This flexible option is used, however in a rather small scale in the market. Thus, to increase consumption of mobile buildings, there is a need for market research that will contribute to find the factors that customer value.

    The purpose of research is to investigate customer values when it leases and/or uses temporary buildings, and possibly encourage new elements that do not exist in the market range yet.

    To obtain the valuation factors have been implemented a literature survey and 13 personal interviews were conducted. Interviews took place with people who use these buildings and those who entered a contract to rent these buildings. The study objects are offices, schools and kindergartens.

    Minimering av risker vid kreditgivning2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Turbulence in the world economy with following liquidity problem in enterprises has lead to negative consequences for banks that creates a need for effective credit risk management. To prevent significant credit losses, banks tries constantly to minimize their risks in credit granting through identifying pitfalls.

    The purpose is to investigate the factors that contribute to the credit losses and illustrate how Nordea can minimize risks in credit granting.

    Data were gathered from the literature review and a case study. The object of study is the Swedish Business Bank Nordea where several credit managers has been interviewed at the regional level. To obtain a volume of credit development in Sweden, gathered the credit granting statistics of the source of Nordea Hypotek AB.

    According to the theory credit losses are depending on direct and indirect factors. While direct factors can be affected by a credit analyst, indirect factors are outside of his influence. It can be stated that Nordea has been succeed in minimizing of risks at the considerable degree, with reservation for some improvements, and that some factors that cause losses the bank manage to keep under control.

    Bank´s fundamental strategy in risk management is to use reasonable credit granting. All of respondents have stressed the importance of thorough inquiry on new credit application and frequent following up suspicions of payment difficulties with existing borrowers. Through these routines can bank capture problematic business transactions and prevent appearance of credit losses.

    Approaching Curriculum Resources: Examining the potential of textbooks and teacher guides to support mathematics learning and teaching2014Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The driving forces of conducting the two studies presented in this thesis are: the strong position of curriculum resources in the mathematics classroom in general; teachers’ faith in curriculum resources to convey the intentions and goals of mathematics education; and the expected benefits to mathematics education through expanding the knowledge base of research in the area of curriculum resources in general, and teacher guides in particular. This thesis builds upon two studies conducted in Sweden. The first is a study on how teachers use teacher guides. The results of this study could be seen as one piece in the building of a theoretical understanding of how teachers use their tools in planning and enacting teaching. The data for Study I were collected through semi-structured interviews with five early-years mathematics teachers. In advance, the teachers were asked to copy the pages from the teacher guide they had used the week before the interview. The analysis of the interviews shows that less experienced teachers desire a wider scope of content in their teacher guide. More experienced teachers desire support from teaching activities, in the design of teaching in classroom practice. Another interesting result was that all teachers in our study, regardless of prior experience, knowledge, beliefs, etc., want the teacher guide to offer connections between theory and practice. The second study investigates what content is represented in Swedish textbooks. The results of this study map the terrain over how the most commonly used textbooks in Sweden construct the topic of proportion and proportional reasoning. My choice of textbooks is based on a questionnaire among all compulsory school mathematics teachers in the sixth largest municipality in Sweden, revealing that two curriculum resources together covered 97% of the classrooms in Grades 7-9. The study provides insights into the strengths and weaknesses in the presented structure regarding proportional reasoning in the most commonly used textbooks in Swedish lower secondary school. Teachers could use these insights when making decisions about how to use their textbooks, and to possibly reconsider how to organize the enactment of the national curriculum in order to develop deep understanding. The analyses could provide authors of teacher guides and textbooks with valuable information to consider regarding structure and design.

    Problemlösning, kontext och kompetens2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Syftet med arbetet är att undersöka hur matematiklärarstudenter ska introducera problemlösning för sina elever och vad som påverkar studenternas tolkningar av problem. Jag har även undersökt vilka kompetenser studenterna anser att en matematiklärare behöver ha för att genomföra en framgångsrik undervisning i matematik genom problemlösning. I undersökningen diskuterar tre grupper med matematiklärarstudenter hur de ska introducera ett problem för eleverna och vilka komprtenser de anser att en matematiklärare behöver ha för att undervisa i matematik genom problemlösning. Resultaten visar att studenterna har olika strategier för att introducera problemlösning för eleverna och att studenternas tolkningar av problemet påverkar introduktionen. Studenterna gör olika tolkningar av problemet beroende av i vilken kontext de tolkar problemet. De har ingen enhetlig bild av vilka kompetenser som krävs av en matematiklärare, för att genomföra en undervisning som svarar mot skolverkets mål.

    The Potential of Dominating Mathematics Textbooks in Sweden to Support the Learning and Teaching of Proportional ReasoningManuscript (preprint) (Other academic)
    Abstract [en]

    Proportional reasoning is a cornerstone in compulsory mathematics education. It is considered to be one of the most challenging topics to tech and learn. This article discusses the potential of two Swedish textbooks to support the teaching and learning of proportion and proportional reasoning. Since curricular resources, such as textbooks are teachers’ most important tools for planning and enacting lessons; the support they offer has great impact on how teaching and learning will be designed. To analyze the textbooks examined here, I use a framework developed by Shield and Dole, based on research. The study provides insights of the strengths and weaknesses in the presented structure regarding proportional reasoning in the most commonly used textbooks in Swedish lower secondary school. Teachers could use these insights, when making decisions about how to use their textbooks. This study is likely to map the terrain of Sweden, due to the textbooks widespread use.

    Investigating the voice of two Swedish mathematics teacher guides2015In: PROCEEDINGS OF THE NINTH CONFERENCE OF THE EUROPEAN SOCIETY FOR RESEARCH IN MATHEMATICS EDUCATION (CERME9) / [ed] Krainer, K Vondrova, N, CHARLES UNIV, FAC EDUC , 2015, p. 3165-3166Conference paper (Refereed)
    Abstract [en]

    This poster presents a study on the voice of two Swedish mathematics teacher guides. We have made a content analysis of teacher guides to the two most commonly used mathematics textbooks in Swedish lower secondary school Grades 7 to 9. Our theoretical stance is that curriculum resources can support teachers pedagogical design capacity. Our analysis shows that the voice of both guides speaks through the teacher with narratives and scripted instructions, instead of making visible the strengths and weaknesses with different teaching design considerations. The results could be used to further elaborate on how the teacher guides can be designed to support the pedagogical design capacity for a range of different teachers.

    When teacher guides speak “past” the teacher: Two Swedish mathematics teacher guides2017Conference paper (Refereed)
    Abstract [en]

    In this paper we report on how two Swedish mathematics teacher guides communicate with teachers. We have analysed the guides from the theoretical stance that curriculum resources can support teachers’ pedagogical design capacity, i.e. support them to find productive ways to adapt curriculum resources. To investigate the guides we studied the “voice” by the use of language, focusing on personal pronouns and imperatives. Our analysis shows that both guides often speak “through” the teacher with narratives and scripted instructions, rather than “to” the teacher about strengths and weaknesses with different teaching design considerations. The results also show that in addition to speaking “to” or “through” guides can speak “past” the teacher, positioning her as an observer of the interaction between students and textbooks. This language construction is unexpected and may thus be seen as expanding the framework for investigating the “voice” of teacher guides.

    HOW ARE MATHEMATICS TEACHER GUIDES USED FOR SUPPORT AND INSPIRATION IN TEACHING?2014Conference paper (Refereed)
    Abstract [en]

    In this study we investigate how teachers talk about their use of mathematics teacher guides for support and inspiration, with the aim of broadening the knowledge of how teachers use these guides in and for teaching. Our second aim is to test whether guidelines for designing educative curriculum material can serve as an analytical tool. The results show that less experienced teachers use a wider scope of content in the teacher guide whereas more experienced teachers use teaching activities1 and support for the design of teaching. Common for all teachers, despite level of experience, is that they want the teacher guide to provide connections between theory and practice. The analytical tool served well for analysing interviews, helping us pay attention to the features of the content discussed.

    Mångkulturallitet i förskolan: En kvalitativ studie om några pedagogers förhållningssätt till mångkulturalitet2013Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att ta reda på vilket förhållningssätt några pedagoger har till mångkulturalitet. Vi har genomfört en kvalitativ studie på två förskolor i ett mångkulturellt område. För att ta reda på vilket förhållningssätt några pedagoger har till mångkulturlitet har vi valt att genomfört fyra observationer och fyra intervjuer med pedagoger i förskolan. Det visade sig att de svenska normerna är ständigt närvarande. Det finns ett dilemma med att synliggöra barnens kulturtillhörigheter, nämligen att barnen blir representanter för en kultur snarare en unik individ. Det framkom också att språket är en viktig del i utvecklandet av en kulturidentitet. Det är därför viktigt att barnen utvecklar sina modersmål för att på så vis utveckla flera kulturtillhörigheter men också för att kunna tillägna sig det svenska språket.

    Kinesiska universitetsstudenters uppfattningar om sexualundervisning för ungdomar i Kina2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sexuality and reproduction are two central parts of human life and they are integrated into our personalities. It is therefore important to create a good foundation for sexual health and wellbeing from an early age. To see adolescents as “ready to act-individuals” and to make them more involved in open dialog discussions contributes to extended possibilities for creating and sustaining a healthy lifestyle. The school is therefore considered as an important arena for health promoting and preventive actions where most adolescents can be reached. An obligated nine years school based education was implemented in China 1986, and school based Sex education became obligated in 2002.

     

    The study aimed to examine Chinese university student’s perceptions of Sexeducation for adolescents (10-19 years) in China and needs for changes and ongoing tendencies of development. Qualitative studies were conducted with three Chinese university students and contact was taken with a key person in China whom translated material for this study alone.

     

    The result showed various constructions of school based Sexeducation in China and that its implementation and construction needs more support. It also showed a need for the development of influence and participation in the school based Sexeducation. A need for creating an improved communication between teachers and students was also expressed and a more salutogenic approach needs to be developed.

     

    Through collaboration with other countries, for example Sweden, can today’s open-minded process of change benefit even more.

    Sexual behavior among Chinese male and female medical university students in Chongqing, China2012Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Sexuality is one of the most fundamental values of life as it affects our behaviors, thoughts and emotions. Young people are an especially essential group for promoting sexual health as it is during adolescents the base for our sexuality is created. The aim of this study was to examine Chinese male and female medical university student’s knowledge and ideas of sexual behavior at Chongqing Medical University in Chongqing, China. An explorative quantitative survey study was conducted at place in Chongqing. The survey study’s result showed that ideas of sexual behavior were seem to be permissive and love-based, and also bi- and homosexuality to be mainly acceptable. The Internet, books and friends were seemed as important sources for knowledge whereas few believed to have received adequate knowledge from school. It was also seemed to be a major lack of knowledge regarding STD’s and how to protect yourself as “safe periods” was believed to be an important contraceptive method. The relationship between contraception and the protection against STD seems to be obscure.

    Unbounded Sparse Census Transform using Genetic Algorithm2019In: 2019 IEEE WINTER CONFERENCE ON APPLICATIONS OF COMPUTER VISION (WACV), IEEE , 2019, p. 1616-1625Conference paper (Refereed)
    Abstract [en]

    The Census Transform (CT) is a well proven method for stereo vision that provides robust matching, with respect to object boundaries, outliers and radiometric distortion, at a low computational cost. Recent CT methods propose patterns for pixel comparison and sparsity, to increase matching accuracy and reduce resource requirements. However, these methods are bounded with respect to symmetry and/or edge length. In this paper, a Genetic algorithm (GA) is applied to find a new and powerful CT method. The proposed method, Genetic Algorithm Census Transform (GACT), is compared with the established CT methods, showing better results for benchmarking datasets. Additional experiments have been performed to study the search space and the correlation between training and evaluation data.

    Abstract [en]

    Healthy lifestyles are an important condition for creating a positive health and dietary habits, physical activity and stress are factors that affect health. As a result of recent changes in society people's lifestyles have changes through unhealthy diet, physical inactivity, and stress has increased. Changing lifestyles have affected public health, and to invest in these areas in public health work can provide significant health benefits. Västmanland County Council operates a project to promote healthy behavior. The project includes "Kom i form gruppen" which is a group that focuses on nutrition, physical activity and stress. The aim was to investigate participants' experiences of participation in "Kom i form gruppen" and if the participation has affected their lifestyles. To answer the purpose, a qualitative approach with interviews used. The result shows that the content of the meetings has not identified any new knowledge. Participation has provided awareness and motivation and appreciation of food habits have been affected varied between participants. The participants' exercise habits have been affected by regular exercise occasions and everyday physical activity. Effect of stress has not been made, but they try to think about to rush less. Lack of time and stress, however, perceived as an impediment to healthy living.

    Abstract [sv]

    Background: When a parent loses its child life will change drastically and assume other conditions. The loss of a child affects the whole human existence, the grief can be very intense as well as in-depth and find expression both on an emotional, physical, mental and spiritual level. Aim: The aim is to describe parents’ experiences of losing a child to illness. Method: Graneheim and Lundmans manifest content analysis method was used to the method based on qualitative raw material in forms of three Swedish autobiographies. Results: The analysis resulted in three categories "interactions in existential chaos", "the unimaginable has happened" and "to live with the grief". The categories describe different stages in the loss of a child, from the contact with health professionals to fighting their way through and live with the grief following the death of their child. Conclusion: The interaction parent’s get from health professionals have big impact on the experience of losing their child. It is not possible to escape from the grief that manifests when you lose a child, the grief has to be processed during a long time but this is necessary for the ability to get through the grief and to finally get on with life.

    Språkets betydelse i  matematikundervisningen i de tidigare åldrarna2009Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här studiens syfte var att få reda på hurdant språk lärare i år 1-3 samt förskolelärare anser ska användas i matematikundervisningen. Studien fokuserar  också på hur det formella matematiskspråket används. Alltför ofta används ett vardagligt språk i matematiken istället för att använda formella begrepp. Vi ville genom denna studie få reda på lärares och förskolelärares syn på språket i matematikundervisningen. För att få in empiriskt material genomfördes en enkätundersökning som var både kvantitativ och kvalitativ. 51 respondenter medverkade i enkätundersökningen som handlade om hur de uppfattade vissa påståenden som handlade om användandet av språket i matematiken. Enkäterna genomfördes vid åtta olika skolor. I studien jämfördes lärarnas och förskolelärarnas resultat mot varandra, detta för att se om det fanns någon skillnad i deras reflektioner om språket. Resultatet visar på att det fanns en viss skillnad i tankesättet mellan lärarna och förskolelärarna. Av resultatet såg vi att pedagogerna tyckte att ett formellt matematiskt språk är viktigt i matematikundervisningen.

    Work resumption or not after rehabilitation?: A descriptive study from six social insurance offices2004In: International Journal of Rehabilitation Research, ISSN 0342-5282, E-ISSN 1473-5660, Vol. 27, no 3, p. 171-180Article in journal (Refereed)
    Abstract [en]

    The objective of this study was to describe measures and outcomes of vocational rehabilitation at six local national insurance offices in the same county in Sweden. Data were collected from mainframe registers and other records at each office. There were great differences in sickness allowance, incapacity rate, selected rehabilitation measures and resuming work. The percentage of sick-listed people who received any rehabilitation measure differed from 1.2 to 8.7%. The gender distribution for the study population was 36% men and 64% women and the predominant diagnosis was musculoskeletal pain conditions, which was followed by psychiatric disorders. Outcomes varied from office B, which reported 58% fully fit after completed planned rehabilitation, to office C, which reported only 24% fully fit. The clear differences in outcome between the offices indicate that various rehabilitation measures differ in effectiveness. The rehabilitation measure 'investigation of working ability' was not linked to any great proportion of people resuming work, but showed a greater correspondence to full disability pension. There were also large differences in social and demographic factors in the different municipalities. The effect of these on the rehabilitation process requires further investigation.

    Disability pension despite vocational rehabilitation?: A study from six social insurance offices of a county2005In: International Journal of Rehabilitation Research, ISSN 0342-5282, E-ISSN 1473-5660, Vol. 28, no 1, p. 33-42Article in journal (Refereed)
    Abstract [en]

    Many long-term sick-listed individuals move from vocational rehabilitation to pension, rather than reaching the goal of return to work. There is thus reason to consider whether rehabilitation resources are being used optimally. Individuals receiving disability pensions are consuming financial and personnel resources at the insurance offices and also consume a large amount of health care. The general objective of the study was to evaluate the proportion of individuals granted vocational rehabilitation but then obtaining temporary or permanent disability pensions. All persons receiving any kind of rehabilitation and attending one of six local national insurance offices in a county in Sweden in 1998 and 1999 were studied. A 2-year follow-up was carried out to assess changes in status among those who had received temporary disability pensions. Of all individuals receiving rehabilitation, 46.2% ended up with a disability pension allowance. In addition, a large portion of the temporary disability pensions was transformed to permanent disability pensions within 2 years. For clients with a temporary disability pension, the rate of resuming work was close to nil. Among rehabilitation measures, investigation showed the lowest figures of work resumption while job training showed the best outcome in this respect. The study concluded that a large portion of the financial and personnel resources allocated by the national insurance offices to rehabilitation resulted in disability pensions.

    Physical inactivity is a public health problem and lead to bad health in the population. Healthcare in Västmanland has started the process of prescribing physical activity (OFA) to improvehealth. Sport is an important participant in prescribed physical activity and the sportseducational association, SISU Idrottsutbildarna, is organizing activity leadership training.They educate activity leaders in accepting patient’s prescribed physical activity. The aim ofthe thesis was to study the experiences of Activity Leaders in Västmanland have about theactivity leaders training and the perceptions they have about prescribed physical activity. Toanswer the thesis, six qualitative interviews carried out and analyzed with the help ofconcentration of the contents. The Activity Leaders’ experiences of the education aregenerally positive and their perceptions of prescribed physical activity vary. They believe thatthe activity leadership training can be improved and they are critical of that works are notstarted in a desirable manner and that health care does not prescribe group activities in agreater extent. Activity Leaders feel that the exchange of experiences, greater disseminationof information and health care employees' attitudes to OFA are important elements to improvethe process of prescribed physical activity. Activity Leaders welcomed the future with regardto prescribed physical activity, but that the current economic situation and the lack ofsubsidies will delay the work. Because the work of prescribed physical activity are not yethappened makes it difficult for the Activity Leaders to actively work with prescribed physicalactivity.Physical inactivity is a public health problem and lead to bad health in the population.

    En studie om hur några lärare och skolledre ser på skolplikt och kunskapsinlärning i grundsärskolan2015Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att undersöka synen på kunskap, skolplikt och närvaro hos lärare och skolledare i grundsärskolan. Genom intervjuer på 6 olika skolor frågade vi 15 informanter om deras syn på skolplikt för elever i grundsärskolan och hur de ser på kunskapsinlärning och den nya läroplanen. Intervjuerna analyserades med utgångspunkt från studiens frågeställningar och likheter och skillnader söktes i datamaterialet. Resultatet av vår analys var temana:

    Elevernas närvaro, Lärares och skolledares syn på kunskap, Lärares och skolledares syn på skolplikt och närvaro och Lärares och skolledares syn på kunskap kopplat till deras syn på närvaro/frånvaro. Resultatet visade att alla informanterna var överens om att skolplikten är självklar och att grundsärskolan har blivit mer inriktad på kunskapsinlärning. Vi ville även undersöka hur rutiner kring frånvaroanmälan sköttes och hur en eventuell hög frånvaro följdes upp på de skolor vi besökte. Det resultat vi fick fram visade att det fanns många olika rutiner kring rapportering av frånvaro. Några av skolorna skötte sin rapportering via digitala system, andra skolor använde papper och penna. Alla skolor följde upp frånvaron i form av möte med vårdnadshavaren och elevhälsan och i de fall det ansågs behövas även med socialtjänsten. Vår studie visar att de flesta informanterna var av uppfattningen att det finns mycket kvar att arbeta med när det gäller synen på kunskap och inlärning hos omgivningen då informanterna som själva arbetar i grundsärskolan såg kunskap och inlärning som en självklarhet men de upplevde att omgivningen såg på grundsärskolan som mer omsorgsinriktad

    Lärmiljöns betydelse i den fria leken: En kvalitativ studie ur förskollärares perspektiv2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med vår studie är att studera hur förskollärare uppfattar lärmiljöns betydelse för den fria leken samt hur förskollärare aktivt arbetar med lärmiljön för att främja den fria leken. Vi samlade in det empiriska underlaget genom åtta kvalitativa semistrukturerade intervjuer med frågor utformade till förskollärare. Resultatet visar en samstämmig bild hos informanterna där lärmiljön framstår som betydelsefull i förhållande till barns fria lek, resultatet visar även på att en väl genomtänkt lärmiljö där fokus ligger på barns intressen främjar barns fria lek och därigenom barns utveckling och lärande.

    Selection of clients for vocational rehabilitation at six local social insurance offices: a combined register and questionnaire study on rehabilitation measures and attitudes among social insurance officers.2008In: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 40, no 3, p. 178-184Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim of this study was to evaluate possible differences between local social insurance offices with regard to their selection of clients for vocational rehabilitation. A further aim was to determine whether social insurance officers from different local insurance offices have uniform attitudes regarding professional practice in their application of the insurance system. METHODS: A register-based investigation of 815 vocational rehabilitees served by 6 local social insurance offices in a Swedish county. The study was supplemented with a questionnaire to 30 officers about attitudes to social insurance. RESULTS: The office with the lowest rate of sick-listing periods exceeding one year, and a high frequency of employment training, showed the highest degree of work resumption and the lowest pension rate after vocational rehabilitation. There were wide differences in attitude among the local social insurance officers regarding professional practice in their application of the system. CONCLUSION: Intra-county differences occur in handling people on sick-leave who undergo vocational rehabilitation. The local social insurance offices with the highest and lowest outcome rates of work resumption and disability pension, respectively, select clients for vocational rehabilitation from different categories of cases. Social insurance officers from different local offices differ in their attitudes towards the social insurance system and its clients.

    Work resumption after vocational rehabilitation: a follow-up two years after completed rehabilitation2007In: Work: A journal of Prevention, Assesment and rehabilitation, ISSN 1051-9815, E-ISSN 1875-9270, Vol. 28, no 4, p. 343-354Article in journal (Refereed)
    Abstract [en]

    A short-term evaluation of vocational rehabilitation (VR) may give conclusions not automatically applicable over a longer term. The present study follows up alterations in work resumption or in social insurance benefits from the time of completed VR and during the following two years. AIM: The primary objective was to evaluate work resumption among previous sick-leavers granted vocational rehabilitation. The aim of the follow-up was to assess the stability of the outcome of VR over time and to analyse factors of importance for clients that remained at work. METHOD: A register investigation was based on 815 cases where the clients had taken part in vocational rehabilitation and were served by one of six local social insurance offices of a Swedish county. RESULTS: Of the clients studied, 52.4% had attained full working capacity The proportion had decreased to 37.4% two years later. One factor that differed between those who resumed work and those who returned to sick leave was the duration of the previous sick-leave period. Those who returned to work had had shorter sick leave, had jobs to return to and had received job training as a vocational rehabilitation measure. CONCLUSIONS: The clients with the best chances of being in work two years after completed vocational rehabilitation were those with short sickness absence, who had been selected for job training as a vocational rehabilitation, were aged 16-29 years and were employed in industry.

    Medarbetares personlighet och deras attityd till olika typer av ledarskap2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Med fokus på förändring, flexibilitet och personlig utveckling har det agila

    ledarskapet utvecklats och växt fram. En ledarskapsstil och arbetssätt som

    blir allt vanligare bland organisationer där många företag påstår sig på

    något sätt arbeta med agila metoder. Denna studie undersökte sambandet

    mellan medarbetares personlighet och attityd till olika ledarskapsstilar,

    med fokus på den agila. En webbaserad enkätundersökning gjordes med

    129 deltagare, 83 kvinnor, 45 män och en utan kön. Enkäten innehöll

    personlighetstestet Big Five Inventory samt tre vinjetter kring

    transformativt-, transaktionellt- och agilt ledarskap. Resultatet visade att

    deltagare med höga värden på extraversion och öppenhet och låga värden

    på neuroticism tenderade ha mer positiv attityd till den agila

    ledarskapsstilen. Män var mer positiv inställda till transaktionellt ledarskap

    än kvinnor. Avslutningsvis diskuteras generaliserbarheten i resultatet

    utifrån de tillgänglighetsurval som studien hade samt att de resultat som

    redovisas kan vara till hjälp för organisationer i exempelvis rekrytering

    och utveckling av ledarskapskompetenser.
