    Bluetooth-implementation för Netbiter EC3502014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In industries today the demand for reading the state of industrial equipment and thus prevent machine breakdown, is increasing. The company HMS Industrial Networks AB has a product on the market, Netbiter EC350 that is used to read sensors and thus find out the condition of industrial equipment. By reporting scanned data to users through a cloud service, users can keep track of their equipment.

     

    When developing Netbiter EC350 a slot was made for a Bluetooth module to offer clients a wireless reading in future developments. In this project a prototype was made to show how this Bluetooth communication can be implemented.

     

    The goal of the project was to create a Bluetooth communication between a Bluetooth sensor and Netbiter EC350. A user interface was made to allow the user to read sensor values.

     

    The result of the project shows how a Bluetooth communication can be implemented to read sensors wireless and therefore it fulfills its purpose and goal. The user can find connectable Bluetooth devices, connect to a device and read measured values through a user interface.

     

    The prototype demonstrates how a Bluetooth communication with a Netbiter EC350 can be implemented and the project is therefore considered to be a good basis for future development.

    The Capital Structure of Swedish Subsidiaries Abroad: Including an Empirical Study of Swedish Manufacturing Subsidaries in Malaysia1996Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]
    The emerging markets in South East Asia are attracing world-wide interrest. They have experienced an average growth in GDP of 7.7.% per year since 1986. The four Tigers have been at the centre of attention but also Thailand and Malaysia have endured economic growht. Many multinational companies have set up subsidiaries in this region. These emerging markets share of foreign investment accounted for 60% of all investments last year. When establishing a subsidiary abroad manay considerations need to be taken into consideration, one of which is the capital structure of the company. The issue for this thesis was to summaries the capital structure determinants identified in theories and previous studies and determine their relativ importance for Swedish subsidiaries in Malaysia. First the company-related capital structure determinants were discussed and thereafter the international factors. This made up the frame of reference for the thesis. The study was made from a micro economic perspective with the focus on the company. A quantitative medhodology was chosen since it was thought to be suitable considering the problem statement and the objectives for this thesis. A questionnaire was sent to Swedish multinational companies with a manufacturing subsidiary in Malaysia. However, the sample proved to be small, and only four valid answers were recived, which is the main limitation of this thesis. The first objective was to explain the determinants influencing the capital structure of multinational companies. This was done in the second chapter of the thesis and summarised in an exhibit. The second objective was to describe the capital structure fo Swedish subsidiaries in Malaysia. The companies included in this study were financed by 40% internal sources, 14% of equity and 46% of debt. This diverges from the result of Singh´s study (1995), but he studied domestic Malaysian companies and this study focused on Swedish subsidiaries in Malaysia. However it does correspond rather well with William and Sekely (1988) who claim that developing countries have a lowe debt ratio than industrialised countries. The third objective was to find the determinants relative importance for the Swedish subsidiaries in Malaysia. Since the sample was very small no internal ranking was statedd. However, this study suggests that local borrowing as a hedge against inflation and devaluation could be an important facot. This will however not influence the debt ratio provided that debt is exchanged for debt. Ti will affect the cost of capital since capital markets are segmented and the real rates of interest do differ between Sweden and Malaysia. The parent companies can provide guarantees and provede equity capital in order for the subsidiaries to be able to raise local financing. Another advantage of debt os the reduction in political resk which it induces. For the two wholly owned subsidiaries it is important to keep the control thus not allowing any local equity capital, and the two joint ventures pointed out the liquidity of assets as a capital structure determinant. None of the subsidiaries has a debt ratio goal but take advantage of favourable financing oppurtunities as they occur. Since hedging often is centralised to the parent company, it could be that the subsidiary´s position are left open.

    Patienters tillfredsställelse av smärtlindring postoperativt2000Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    I ett snabbt tekniskt utvecklande samhälle där individens roll i sjukvården växer, krävs allt mer patientanpassad sjukvård. Litteraturstudiens syfte var att belysa patienters tillfredställelse av smärtlindring postoperativt. I resultatet har patienternas tillfredställelse belysts samt mätmetoder för begreppet beskrivits. Faktorer som påverkar tillfredställelsen av konventionell respektive patientkontollerad smärtlindring (PCA) postoperativt har analyserats. Enligt vår uppfattning visar studierna en tendens till att PCA ger bättre tillfredsställelse än konventionell smärtlindring. Detta kan komma att stärkas i framtida studier.

    Att vara husmor: ett yrke värt semester? En inblick i den svenska politiska debatten under 30-och 40-talet om kvinnans roll i samhället2003Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    Att den person som arbetade skulle ha semester, sågs av många människor vid semesterlagstiftningens införande under slutet av 30-talet som självklart. Svårare var däremot att avgöra vem som arbetade, och hur begreppet arbete skulle definieras. Hemmafrun, hemmet och arbetet som utfördes i denna sfär kom under 30- och 40-talen upp till politisk debatt, då den lilla världen, hemmet och därmed kvinnan, fick en ny ekonomisk och politisk betydelse. Syftet med denna uppsats är dels att visa hur den passar in i Yvonne Hirdmans analys av 1930-talets folkhemspolitik med dess ambition att utveckla ett nytt husmoderskontrakt, dels att bidra till förståelsen av varför debatten var så laddad genom att med utgångspunkt i Johan Asplunds begrepp ”tankefigur” visa hur husmoderssemestern utmanade etablerade föreställningar om semester och arbete.

    Let Me Dance:: Exploring Narratology in Mineko Iwasaki’s Geisha of Gion2004Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]
    Differnt techniques can be used when telling a story. A narrator might lie, skip parts of the story or exaggerate the facts in order the reader in a certain direction. These are some of the narratological tools explored in this essay through a study of Mineko Iwasaki’s autobiographical Geisha of Gion. I use different narratological theories when analysning the following questions: what kond of narrator is Mineko? Is she reliable or unreliable? Does her book have the typical features of a female writer, or does her way of telling her story contain elements that are often considered male? My conclusions are that Mineko writes in a typically male language when making straightforward descriptions. Further, Mineko strikes me as an unreliable narrator when describing events that took place more than 40 years ago un the form of dialogues, rendered word by word. I believe that it is impossible to remember a dialogue as precisely as Mineko is retelling it.

    Erfarna klättrares upplevelse av arousal och hantering av anxiety2007Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Syftet med studien var att få en djupare förståelse för vad som ger upphov till anxiety hos erfarna klättrare och hur de hanterar (coping) somatisk såväl som kognitiv anxiety vid traditionell klättring. Skiljer sig copingstrategierna mellan män och kvinnor samt är det sökandet efter arousal som motiverar till traditionell klippklättring. En kvalitativ undersökning genomfördes med en semistrukturerad intervjuguide som underlag. Nio stycken erfarna klättrare (män = 6, kvinnor = 3) mellan 23 och 46 år (M = 33.4 år) inom traditionell klättring intervjuades. Resultatet visade att alla klättrarna använde sig av positiv self-talk, medan visualisering endast användes av ett fåtal som ett sätt att återfå fokus och att samla sig. Viktiga faktorer bakom hanteringen av anxiety var erfarenhet och kunskap.

    Hållfasthet i helväggselement av cementbunden träull2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Cement bonded wood-wool as external walls have been used around the world since the 1980s. They can have different appearances, wood-wool slabs connected to each other into larger wall elements that are raised between concrete columns and beams. Another type is hollow wood-wool blocks that are stacked on each other and filled with concrete to make an external wall. In 2004 a new building system was launched in Sweden, large prefabricated wall elements of wood-wool. They are connected to each other with concrete columns and beams integrated in the elements to make an external wall. This report is looking into if the concrete beams and columns for the building system are needed. In the report three different tests were made to get the mechanical properties of the prefabricated wood-wool elements. Results showed that there was a large different in the density between the wall elements and it also showed that the modulus of rupture varied between 0.248-0.449 MPa on three identical wall elements. The characteristic modulus of rupture was three times higher than documented in previous reports of a similar wall. The conclusion of this report is that the concrete beams and columns should still be in the wall system.

    Construct validity and test-retest reliability of a rotational maximum strength test and rotational power test in 1080 Quantum2016Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Explosive rotational movements are parts of many sports such as golf, tennis and baseball. Rotational strength and power tests exist, but valid and reliable tests to measure standing rotational strength and standing rotational power are lacking. 1080 Quantum is a machine wich can measure, speed, force and power and has several different resistance modes was used for testing rotational power and strength in this study. Aim: The aim was to investigate the validity and reliability of two new standing Quantum rotational tests; one measuring maximal rotational strength (1RM) and one measuring rotational power. Methods: Fifteen subjects, 8 men and 7 women, with at least one year of experience of resistance training participated in the study. The two new tests were: the Quantum power rotational test (PRT) and the Quantum 1RM rotational test (1RMRT). Testing occured during two sessions and during the first session construct validity of the two new rotational tests was assessed with a standing medicine ball throw (MB) and a sitting rotational power test (SRT). During the second session PRT and 1RMRT were tested for test-retest reliability. To study construct validity á priori hypothesis were stated and data were analyzed with Spearman´s correlation coefficent (rs). Intra correaltion coefficient (ICC) was used for test-retest reliability for PRT and 1RMRT. Results: Priori hypotheses were all fullfilled. Correlations found were considered good between PRT and MB (rs=0.80), moderate between PRT and SRT (rs=0.52), excellent between 1RMRT and MB (rs=0.90), moderate between 1RMRT and SRT (rs=0.73) and good between PRT and 1RMRT (rs=0.81). Excellent test-retest reliability was found for PRT (ICC=0.94, 95% CI (0.80-0.99)) and 1RMRT (ICC=0.98, 95% CI (0.92-0.99)) Conclusion: The two new rotational tests performed in 1080 Quantum both assessed construct validity and test-retest reliability. PRT can be used to measure standing rotational power and 1RMRT can be used to measure standing rotational maximum strength.

    Att bryta mönster: Att inkludera nya generationens invandrare i idrottsundervisning2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sverige genomgår en utveckling där en generationsväxling som har formats av tidigareflyktingströmmar från exempelvis forna Jugoslavien och Mellanöstern. Även idag tar Sverigeemot och hjälper individer med utländsk bakgrund in i det svenska samhället. Detta innebäratt skolor också står inför en förändring som skall anpassa sig till behovet som finns isamhället. Det övergripande syftet i detta arbete är att undersöka hur elever med utländskbakgrund i årskurs nio i en mindre svensk kommun upplever sin idrottsundervisning utifråninkluderande aspekter. Ett delsyfte är att undersöka hur läraren upplever att hon/han formarsin idrottsundervisning utifrån inkluderande aspekter. Denna studie har bedrivits medkvalitativa forskningsmetoder, metoderna vi har använt oss av är intervjuer och observationer.Insamlingen av empirisk data är gjord på två grundskolor i mellersta Sverige med sammanlagttvå lärare och sex elever. I resultatet går det att utläsa att lärarna anser att delaktigheten inomundervisningen är viktigt. Från elevernas upplevelser kan vi konstatera att de upplever attläraren inte lyssnar på dem, samt att genomgångarna av olika aktiviteter kan brista. Resultatetvisar också att elevernas motivation gentemot och delaktighet i idrottsundervisningen kanavta. Att relationen mellan de olika aktörerna inom idrottsundervisningen kan bidra till ökadmotivation, men även hämma den.

    I inkluderingens fotspår2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med detta arbete är att granska huruvida elever med muslimsk bakgrund upplever sitt deltagande i religionsundervisningen, samt hur lärarnas undervisningsmetoder arbetas med inom religionsundervisningen. Vi ville undersöka hur elever med muslimsk bakgrund upplever sitt deltagande i religionsundervisningen och hur samspelet mellan eleverna och läraren är. Vi undersökte även vilka metoder läraren använder sig av inom religionsundervisningen, men även för att etablera relationer till eleverna. Vi har i denna uppsats arbetat med två kvalitativa arbetsmetoder, då vi intervjuade lärare och elever, men också observerade de på religionsundervisningen. Denna studie gjordes på tre grundskolor och vi intervjuade sammanlagt tre lärare och sex elever. På varje skola intervjuade vi en lärare och två elever. Det visade sig att lärarens uppfattningar inte alltid stämde överens med beskrivningen från eleverna. Lärarna försöker vara innovativa i sin undervisning samt att de försöker inkludera alla elever, men att undervisnings upplägget och materialet inte motsvarar elevernas önskemål och åsikter.

    IDENTIFIERING AV ELEKTRONIKSKROT2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report is the result of a survey carried out by two students at Halmstad University. The study was conducted at the request of the recycling company, with the purpose to explore opportunities for streamlining the screening pro- cess of electronic waste products. The question that was asked was if RFID could be used for identification of the scrap. The project members started their work to investigate if RFID was the best identification method where the advantages and disadvantages of various automated systems were com- pared. The conclusion drawn was that RFID could be a viable solution in the future, provided that manufacturers of electronics integrate RFID tags into their products. Given that increasingly more producers are using RFID to locate and identify their products during production and the falling price of passive tags, it is possible that labeling products with RFID tags could become a standard, both for more efficient logistics and a more efficient re- cycling process.

    An Acumen/NS-3 integration for modeling networked Cyber-Physical Systems2014Conference paper (Refereed)
    Abstract [en]

    Capturing physical phenomena such as node mobility or wave propagation is challenging in current network simulators, and is mostly achieved through crude abstractions. Despite being operationally efficient, such abstractions adversely affect simulation credibility. To realize more accurate modeling, we are currently developing a simulation environment integrating a hybrid modeling language into a mainstream network simulator. This paper gives a preliminary overview of our efforts. For illustration, an example simulation scenario with some basic mobility is described. © 2014 IEEE.

    End of life scenarios for the Re-load pallets-how different waste scenarios impacts the life cycle environmental impact comparison with other pallet type2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Increasing consumption and transportation gears the use of transport utilities which cause environmental effects over the globe. Environmental performance of three different types of pallets such as Re-load, plastic and corrugated fibreboard pallets are evaluated in this project. LCA tool is used to assess and compare their environmental performance in all phase of their life cycle but more focusing on end of life phase.

     

    This study gives more emphasis to waste treatment options such as incineration, landfilling and recycling. Three different end of life scenarios have been used in this study such as 100% incineration, 100% landfilling and 100% recycling.

     

    This study includes results of all the phases of all three types of pallets which are analysed in this report. More detailed results could be seen in excel sheets. Results of impact analysis tells that landfilling contributes to 14793 Kg CO2 of global warming potential in case of corrugated pallets. Incineration contributes to 12148.6 Kg CO2 of global warming potential. Recycling contributes to 7136 Kg CO2 of global warming. Re-load pallets show the major contribution of global warming is from landfilling approx 813.2 Kg CO2 of global warming potential. Recycling and incineration contribute to 438 Kg CO2 and 726.7 Kg CO2 of global warming potential respectively. In plastic case incineration contributes the most to global warming approximate 1183.8 Kg CO2 of global warming potential. Landfilling and recycling contribute almost the same approximate 932.6 Kg CO2 of global warming potential and 924.5 Kg CO2 of global warming potential respectively. Acidification impact show corrugated pallets cause high emissions when they are treat with landfilling and give negative values of incineration. In Eutriphication impact corrugated pallets are considered better in a sence they are inbetween 150 and 100 kg of PO-4. Re-load pallets give the least values when they are applied to different end of life scenarios.

     

    According to the results recycling could be replace other waste treatment options because of less impact through out the end of life. Secondly, Reload pallets represent a environmental friendly product which can be improved more after this study. Lack of LCI data is the major problem in this study because it is not easily accessible and it is very time consuming part of this study. Results might be different if more data is available.

     

    This study can be helpful for further study, for instance more replaceable scenarios will show different results for all three types of pallets. Moreover, it helps to compare more pallet types which are already in the market or propose to come in the market.

    Att leva med diagnosen hjärtsvikt2000Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    Hjärtsvikt är en kronisk sjukdom med varierande symtom, som leder till begränsningar och osäkerhet. Den stress och osäkerhet som sjukdomen för med sig kan vara en påfrestning både för patienten och dennes anhöriga. Alltför ofta återinläggs patienten på sjukhus, vilket blir en ond cirkel som kan brytas av ökat samarbete mellan sjuksköterskan och patienten genom att förbättra egenvårdsmöjligheterna. Orems omvårdnadsteori beskriver vilka omständigheter som föreligger när en människa är i behov av omvårdnad. Patientens behov av omvårdnad beskrivs i tre delteorier där målet är att patienten, närstående och sjuksköterskan tillsammans bildar ett omvårdnadssystem. Syftet var att beskriva hur det är att leva med diagnosen hjärtsvikt. Sökning gjordes i databaser och manuellt i högskolans bibliotek. Studien omfattar 25 vetenskapliga publikationer. Resultatet visar att patienterna upplever osäkerhet, begränsningar och behov av stöd från närstående och sjuksköterska. Information beträffande sjukdomens symtom, behandling och förlopp underlättar för patienten att leva med sin sjukdom. Kunskap om egenvårdsmöjligheter leder till tillfredsställelse. Sjuksköterskan kan utifrån Orems omvårdnadsteori, föra patienten genom krisen som diagnosen kan innebära. Genom att hjälpa patienten att se möjligheterna, kan ökad livskvalitet uppnås både hos patienten och deras anhöriga. Sjuksköterskans stödjande roll ger patienten styrka, tillfredsställelse och ett sammanhang i den nya livssituationen. Sjukvårdens minskade resurser gör att egenvård blir ett viktigt komplement i vården i framtiden, varför ytterligare forskning inom detta område är angeläget.

    Stability analysis of the t-SNE algorithm for human activity pattern data2018Conference paper (Refereed)
    Abstract [en]

    Health technological systems learning from and reacting on how humans behave in sensor equipped environments are today being commercialized. These systems rely on the assumptions that training data and testing data share the same feature space, and residing from the same underlying distribution - which is commonly unrealistic in real-world applications. Instead, the use of transfer learning could be considered. In order to transfer knowledge between a source and a target domain these should be mapped to a common latent feature space. In this work, the dimensionality reduction algorithm t-SNE is used to map data to a similar feature space and is further investigated through a proposed novel analysis of output stability. The proposed analysis, Normalized Linear Procrustes Analysis (NLPA) extends the existing Procrustes and Local Procrustes algorithms for aligning manifolds. The methods are tested on data reflecting human behaviour patterns from data collected in a smart home environment. Results show high partial output stability for the t-SNE algorithm for the tested input data for which NLPA is able to detect clusters which are individually aligned and compared. The results highlight the importance of understanding output stability before incorporating dimensionality reduction algorithms into further computation, e.g. for transfer learning.

    Design and Implementation of an Audio Codec (AMR-WB) using Dataflow Programming Language CAL in the OpenDF Environment2010Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Over the last three decades, computer architects have been able to achieve an increase in performance for single processors by, e.g., increasing clock speed, introducing cache memories and using instruction level parallelism. However, because of power consumption and heat dissipation constraints, this trend is going to cease. In recent times, hardware engineers have instead moved to new chip architectures with multiple processor cores on a single chip. With multi-core processors, applications can complete more total work than with one core alone. To take advantage of multi-core processors, we have to develop parallel applications that assign tasks to different cores. On each core, pipeline, data and task parallelization can be used to achieve higher performance. Dataflow programming languages are attractive for achieving parallelism because of their high-level, machine-independent, implicitly parallel notation and because of their fine-grain parallelism. These features are essential for obtaining effective, scalable utilization of multi-core processors.

    In this thesis work we have parallelized an existing audio codec - Adaptive Multi-Rate Wide Band (AMR-WB) - written in the C language for single core processor. The target platform is a multi-core AMR11 MP developer board. The final result of the efforts is a working AMR-WB encoder implemented in CAL and running in the OpenDF simulator. The C specification of the AMR-WB encoder was analysed with respect to dataflow and parallelism. The final implementation was developed in the CAL Actor Language, with the goal of exposing available parallelism - different dataflows - as well as removing unwanted data dependencies. Our thesis work discusses mapping techniques and guidelines that we followed and which can be used in any future work regarding mapping C based applications to CAL. We also propose solutions for some specific dependencies that were revealed in the AMR-WB encoder analysis and suggest further investigation of possible modifications to the encoder to enable more efficient implementation on a multi-core target system.

    Abstract [en]

    This study describes the daily life and management strategies of young informal carers of family members or friends with mental illness. Twelve young adults (three men and nine women; 16-25 years old) in Sweden were voluntarily recruited between February and May 2008. Data collected through eight individual semi-structured interviews and one focus group interview were analysed using qualitative content analysis. The findings revealed nine subthemes that were further grouped into three main themes: showing concern, providing support and using management strategies. Participants lived in constant readiness for something unexpected to happen to the person they cared for, and their role in the relationship could change quickly from family member or friend to guardian or supervisor. Supporting a friend was considered as large a personal responsibility as supporting a family member. Their management strategies were based on individual capacities and their ability to step aside should the situation become too demanding. These young informal carers need support in caring for the mentally ill. As the internet becomes increasingly fundamental to daily life, support could be provided most effectively through person-centred web sites.

    Need and Usage of Different Kind of Support among Young Informal Carers of Persons with Mental Illness2014Conference paper (Refereed)
    Abstract [en]

    Background: The high prevalence of mental illness among young person’s means that their relatives and close friends are exposed to stress by having to take on the responsibility for the support of family members or friends in difficult situations of life when suffering from mental illness. Young informal carers have shown to be exposed to a great burden in which they put their own daily tasks aside in order to stay close to the person who suffers from mental illness. Objective: Explore how young (16–25) informal carers of a person with a mental illness experience and use different kind of support, such as web-support, counseling, and group counseling, friends, family, relatives support societies, health care services etc. Method: In a mixed method approach, we first interviewed 12 young carers, and 241 completed a self-administered questionnaire. While the young carers strive to maintain control, their main support seems to be others in their lives, who often define the situation differently. Results: The carers said web-support, counseling, and group counseling might be helpful, yet very few had any professional support. The results also showed that the young informal carers’ safety net is their social network and the person who suffer from mental illness. Conclusion: Young informal carers are in need of a combination of web-based and face-to-face person-centered support, but they do not receive it. Professional support is required. Further studies about the needs of young informal carers of persons with mental illness especially those supporting friends, is necessary to gain before planning to start support interventions for them.

    Effectiveness of web-based versus folder support interventions for young informal carers of persons with mental illness: a randomized controlled trial2014In: Patient Education and Counseling, ISSN 0738-3991, E-ISSN 1873-5134, Vol. 94, no 3, p. 362-371Article in journal (Refereed)
    Abstract [en]

    Objective: Compare the impact of two interventions, a web-based support and a folder support, for young persons who care for people who suffer from mental illness. 

    Methods: This study was a randomized control trial, following the CONSORT statements, which compared the impact of two interventions. Primary outcome variable was stress, and secondary outcome variables were caring situation, general self-efficacy, well-being, health, and quality of life of young informal carers (N = 241). Data were collected in June 2010 to April 2011, with self-assessment questionnaires, comparing the two interventions and also to detect changes. 

    Results: The stress levels were high in both groups at baseline, but decreased in the folder group. The folder group had improvement in their caring situation (also different from the web group), general self-efficacy, well-being, and quality of life. The web group showed increase in well-being. 

    Conclusion: Young informal carers who take on the responsibility for people close to them; suffer consequences on their own health. They live in a life-situation characterized by high stress and low wellbeing. This signals a need for support. 

    Practice implications: The non-significant differences show that each intervention can be effective, and that it depends upon the individual's preferences. This highlights the importance of adopting person-centered approach, in which young persons can themselves choose support strategy. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

    Effectiveness of Web-Based versus Folder Support Interventions for Young Informal Carers of Persons with Mental Illness: a Randomized Controlled Trial2013Conference paper (Refereed)
    Abstract [en]

    Background: Changes in psychiatric services mean more young persons have to care for a mentally ill family member or friend while they themselves are in the sensitive transition to adulthood.

    Objective: Compare the impact of two interventions, a web-based support and a folder support, for young persons who care for people who suffer from mental illness.

    Method: This study was a randomized control trial, following the CONSORT statements and eConsort support. Primary outcome variable was stress, and secondary outcome variables were caring situation, general self-efficacy, well-being, health, and quality of life of young informal carers (N=241). Data were collected in June 2010 to April 2011, with self-assessment questionnaires three times, four months apart, comparing the two interventions and also to detect changes.

    Results: The result showed that stress levels were high in both groups at baseline, but decreased significantly in the folder group. The folder group had significant improvement in their caring situation (also significantly different from the web group), general self-efficacy, well-being, and quality of life. The web group show significant increase in well-being.

    Conclusion: Young informal carers who take on the responsibility for people close to them with mental illness; suffer consequences on their own health. They live in a life-situation characterized by high stress and low well-being. This signals a need for support for these young persons.

    Clinical relevance: The findings in this study are uniquely valuable because of the target group and the comparison of two different interventions to support them. The non-significant differences in the data show that each intervention can be effective, and that it depends upon the individual’s preferences. This highlights the importance of adopting person-centred approach, in which young persons can themselves choose support strategy

    The impact of a person-centred web-based intervention on young informal carers of people with mental illness2015In: Abstracts: 19th International Philosophy of Nursing Society (IPONS) conference August 24-26, 2015 Karolinska Institutet, Stockholm, Sweden: Technology, Health Care and Person-centeredness: Beyond Utopia and Dystopia. Thinking the Future., Stockholm: Karolinska Institutet , 2015, p. 4-5Conference paper (Refereed)
    Abstract [en]

    Background: Previous research show that young person’s often take responsibility and offer care and support for significant others who suffer from mental illness. This adoption of responsibility has consequences not only for the mentally ill, but also for the carer. A person-centred support approach to provide the young informal carers of what they are in need of is according to previous research essential, and in need of. As the internet becomes increasingly fundamental to young people in their daily lives, person-centred web-based interventions may be effective in supporting those caring for a person with mental illness.

    Objective: To analyze (according to stress, burden, quality of life, and self-efficacy) the impact of a person-centred web-based intervention (information, education, and support) for young persons who support family members or close friends with mental illness.

    Methods: The study design was prospective and randomized. The sample consisted of young informal carers (N = 241; 16–25 y), where N = 241 completed structured questionnaires at baseline and were allocated to person-centred web-based support (N = 121) respectively folder support (n =120) regarding available support in the society for young persons who support someone suffering from mental illness.

    Results: Data show that the stress levels were high in both groups at the start of the intervention, but decreased in the folder group, who also showed improvements in their caring situation (also different from the web-support group), general self-efficacy, well-being and their quality of life. The group who received person-centred web-based support showed significant increase in their well-being.

    Conclusion: It is of great importance to measure the stress and caring situation of young informal carers of persons with mental illness in order to understand their situation. One type of support could be person-centred web-based, however our results indicate that individuals seek support depending on their individual preferences. Since the responsibility of care has shifted from the health care services to the family and friends of the person suffering from a mental illness, more person- centred care/support interventions should be investigated for further development.

    Caring Situation, Health, Self-efficacy, and Stress in Young Informal Carers of Family and Friends with Mental Illness in Sweden2015In: Issues in Mental Health Nursing, ISSN 0161-2840, E-ISSN 1096-4673, Vol. 36, no 6, p. 407-415Article in journal (Refereed)
    Abstract [en]

    This study compared the caring situation, health, self-efficacy, and stress of young (16–25) informal carers (YICs) supporting a family member with mental illness with that of YICs supporting a friend. A sample of 225 carers, assigned to a family group (n = 97) or a friend group (n = 128) completed the questionnaire. It was found that the family group experiences a lower level of support and friends experienced a lower positive value of caring. No other differences in health, general self-efficacy and stress were found. YICs endure different social situations, which is why further study of the needs of YICs, especially those supporting friends, is urgently needed.

    Orsaker till Somalias importberoende av livsmedel2003Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    Uppsatsen handlar om Somalias importberoende av livsmedel inom jordbruket. Jag tar i uppsatsen upp olika faktorer som ligger bakom detta, t ex livsmedelsbiståndets effekter på livsmedelsproduktionen inom jordbruket och dess effekt på förändring av konsumtionsvanor samt penningutbudets, växelkursregimens, och pen-ningöverföringens effekter på livsmedelsproduktionen inom jordbruket. Jag har delat upp den tiden som uppsatsen undersöker på två perioder. Jag gör uppdelningen för att studera påverkan av fasta väx-elkursen (under period ett) samt andra institutionella myndig-heter som existerade under period ett. Resultatet blev att under perioden 1970-1981 var den somaliska valutan över-värderad samt att regeringens monopolsystem hade stora ne-gativa effekter på livsme-delsproduktionen inom jordbruket. Men under period två 1982-1990 var det livsmedels-biståndet samt dålig prissättning av livsmedelsbiståndet som ledde till livsmedelsproduk-tionens minskning inom jordbruket. Somalias jordbrukare utsattes för stora påtryckningar från olika håll som de inte kunde motstå. Livsmedelsbiståndet medförde ökat livsmedelsutbud på den inhemska markna-den, medan regeringens dåliga prissättning gjorde situationen ännu värre för inhemska producenter på den inhemska marknaden. Billigare importerat livsmedel som orsakades av övervärderad somalisk valuta var ett annat påtryckningsmedel på inhemska producen-ter. De lokala marknaderna var fyllda av billiga livsmedel som importerades till landet medan marknadsandelen av livsmedel som producerat i landet försämrades. Existensen av både livsmedelsbiståndet och importerade livsmedel, medförde att folk ändrade sina konsum-tionsvanor. Förr konsumerade de mest majs och sorghum medan man substituerade ris, mjöl och spagetti efter mitten av 1970-talet. Livsmedelsbiståndet medför att produktionen minskar för mottagare land. Det behövs samarbete, mellan mottagare regering, åkerbru-kare, livsmedelsbiståndsgivare och handelsmän för att åstadkomma bättre resultat.

    Real-Time Support and Energy Efficiency In Wireless Sensor Networks2008Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Wireless sensors nodes are made up of small electronic devices which are capable of sensing, computing and transmitting data from harsh physical environments like a surveillance field. These sensor nodes majorly depend on batteries for energy, which get depleted at a faster rate because of the computation and communication operations they have to perform. Communication protocols can be designed to make efficient utilization of energy resources of a sensor node and to obtain real time functionality. A set of previously reported routing and MAC (Medium Access Control) layer protocols has abilities to achieve energy efficiency and supports real-time functionality. A detailed study of these protocols has been carried out and comparison tables give an overview of the protocol’s performance on some factors like latency, scalability and energy awareness. Conclusions have been drawn using the comparison table parameters of how the protocol performs when utilized for a surveillance application and what kind of tradeoff they show.

    The conclusions and tabular information drawn here are from our theoretical analysis of protocols referred from journals; there is no simulation work done in this thesis.

    Abstract [en]

    Child Health Nurses meet many parents with questions about infant´s food introduction, one of the child health nurse´s tasks is to educate parents on nutrition issues. Studies have shown that parents feel that they get different advice from Child Health Nurses, which can make them uncertain about which advice to follow. The aim of this pilot-study was to describe Child Health Nurse´s experiences of giving nutrition advice to parents at the introduction of solid foods to infants. Four interviews were conducted with Child Health Nurses within Child Health Servicesin Region Halland. Qualitative content analysis was used to analyze the text. The result of the pilot study shows that the Child Health Nurses felt that they gave good nutrition information to the parents related to structural factors of importance in food introduction and family resources and needs at food introduction. A future full-scale survey in the field could provide a basis for structural changes within the Child Health Services and enhanced educational initiatives for both Child Health Nurses and Child Health Nurse students.

    App eller papp?: En studie om hur Matteappen påverkar elevernas motivation2019Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I det här examensarbetet kommer vi att synliggöra hur användning av Matteappen påverkar elevernas motivation i matteundervisning på högstadiet. Syftet med arbetet är att undersöka hur mycket traditionell undervisning skiljer sig från undervisning som använder Matteappen samt vilken inställning elever har till Matteappen. Vi har besökt skolor och genomfört en rad enkäter, fokusgruppsamtal och undersökningar för att få data som möter syftet. Vi har tagit del av tidigare forskningar kring hur digitaliseringen kan påverka elevernas resultat och inställningar till ett visst ämne.

    Enkäterna visar en stor variation över vilken typ av läromedel som eleverna tycker är bäst för dem. Majoriteten av elever anser fortfarande att det är bäst att jobba med matteboken eller blandat med Matteappen. Vår undersökning pekar inte på några större skillnader mellan de olika arbetssätten. Gruppsamtalen har gett oss svar på elevernas inställningar till Matteappen och i vilka sammanhang de tycker det lämpar sig bäst att jobba med de olika läromedlen.

    De resultat vi har kommit fram till pekar på att Matteappen i sig är ett bra verktyg med mycket potential och möjligheter. Den är under utveckling och i nuläget fungerar den mer som en mattebok fast på en iPad. Vår slutsats är att innehållet i appen inte erbjuder mycket nytt för att eleverna ska jobba bättre eller bli mer motiverade, det är snarare de alternativa tjänster som ett digitalt läromedel erbjuder som gör appen attraktiv.

    Tillämpning av batterilager som energitjänsten lastutjämnare: En studie om batterilagring för en medelstor abonnent i Varberg Energis elnät2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis, is a study of battery energy storage and its use as energy source and smoothening of power fluctuation. Studies have been made as a systematic review and a quantitative study. The study has consisted of analysing the power characteristic from a supermarket in the city of Varberg during year 2015. The object has been to evaluate the energy storage and the power smoothing qualities. Therefore the battery energy storages characteristics have been evaluated in this systematic review. For the quantitative study, calculations of the energy storage sizes were made for two separate operation modes. The two different operation modes were named technical dimensioning and economic dimensioning. The function of the technical dimensioning was to smooth the power outlet from the grid, while the function of the economic dimensioning was to enable the supermarket to buy more energy during low-price hours. Based on monthly power characteristics, each dimensioning gave as a result two energy storage possibilities, one in medium and one in small size. The technical dimensioning resulted in battery energy storage of the sizes 617 kWh and 555kWh which is comparable to 7,1% and 5,8% of the daily energy usage of the supermarket. The economic dimensioning resulted in battery energy storage of the sizes 597 kWh and 233kWh which is comparable to 6,8% and 2,8% of the daily energy usage of the supermarket. For optimizing the economic savings, a variation of technical and economic operation mode are needed, depending on calculated power usage through the day and elspot prices. The study shows that a battery storage is difficult to finance. The calculated economic savings were estimated during ideal conditions and without power loss or loss in performance. As a conclusion from this study a battery storage may have a good payback if there are several energy services to be filled.

    Innovation Barriers and Enablers that Affect Productivity in Uganda Building Industry2007In: Journal of Construction in Developing Countries, ISSN 1823-6499, E-ISSN 2180-4222, Vol. 12, no 1, p. 59-75Article in journal (Refereed)
    Abstract [en]

    The construction industry has of recent been blamed for lack of innovation. Lack of innovation in the industry is believed to be responsible for the decreasing or stagnant levels of productivity in comparison with other industries. This paper reviews the major barriers and enables to innovation in general. Propositions were made about the factors that affect innovation in the construction industry which were then formulated into a questionnaire. A survey was made on building contractors in Uganda, a developing country, targeting those with financial strength, large in size, and with high capacity to carry out big projects. The identified factors were then ranked and correlated. The level of training in science, engineering and technical education, and the level of research and development at the industry level are looked at as the greatest innovation enablers in building that will drive forward labour productivity. The size of the domestic market and the level of security are the worst innovation barriers that lead to low productivity in the building industry in Uganda. Contractors, policy makers and the government should address the identified factors in order to improve productivity.

Mötet mellan sjukvårdspersonal och patienter med HIV/AIDS påverkas av sjukvårdpersonalens förhållningssätt, kunskap och rädsla. Syftet med litteraturstudien var att belysa individers upplevelse av att leva med HIV/AIDS samt betydelsen av mötet mellan dessa patienter i omvårdnaden. I metoden har 20 vetenskapliga artiklar bearbetats. Litteraturstudien visade att diagnosen HIV/AIDS påverkade patienternas hälsorelaterade livskvalitet såväl fysiskt som psykiskt och existentiellt. Fysiska påfrestningar av HIV/AIDS var smärta, illamående, viktminskning, sömnproblematik och försämrad rörelseförmåga. Självkänslan påverkades hos individer med HIV/AIDS och kunde uttryckas i stress, oro och osäkerhet. Många upplevde social isolering och ifrågasatte sina liv. Begränsad kunskap, rädsla för smitta samt fördomar hos sjukvårdspersonalen innebar för en stor del av patienterna försämrad livskvalitet eftersom dessa faktorer påverkade sjukvårdspersonalen negativt. Ytterligare forskning inom området är nödvändig för att sjuksköterskor ska kunna inhämta mer kunskap och större förståelse för hur det är att leva med HIV/AIDS och hur deras bemötande påverkar patienterna.

    Officerare som ledare i näringslivet2002Student paper second termStudent thesis
    Abstract [sv]
    Alla nedskärningar som har genomförts i Försvarsmakten den senaste tiden har lett till att många av de officerare som har fått lämna organisationen har sökt sig till näringslivet. Schablonbilderna av hur organisationen och ledarskapet ser ut i Försvarsmakten gentemot i näringslivet skiljer sig dock väsentligt. Vi finner det därför intressant att undersöka varför dessa officerare anställs av rekryterarna i de privata företagen. Vad vill företagen ha ifrån den ”militära” organisationen? För att finna svaret på detta använder vi oss av en tvådelad undersökning. Den första av dessa, som ska analysera vilken ledartyp företagen är ute efter när de anställer officeren, är LEAD-modellen. Denna modell delar in ledare i fyra olika ledartyper, vilka vi använder oss av för att genom en enkätundersökning kunna få fram den ledartyp de undersökta företagen sökte, för att slutligen kunna jämföra denna ledartyp med tidigare undersökningar med LEAD-modellen. Den andra delen av undersökningen nyttjar Morgans organismmetafor och maskinmetafor för att studera om företagen sökte en förändring av sin organisation i samband med officerens anställning. Även för denna del använder vi oss av en enkätundersökning för att tyda företagens intentioner. Denna enkät har besvarats av de i företagen som var ansvariga för rekryteringen. De besvarade enkäterna tyder i båda delarna av undersökningen på att det inte var tal om någon tydlig eller omfattande strategi att gå mot schablonbilden av Försvarsmaktens organisation och ledarskap. Det var istället endast enstaka delar såsom tydligare regler och befattningsbeskrivningar som eftersöktes vid anställningen. Detta tror vi beror dels på att Försvarsmakten inte längre är så ”militärisk” längre och dels på att företagen förväntar sig att den nyanställde tidigare officeren ska anpassa sig till sin nya omgivning.

    Varför har inte Activity: Based Costing slagit igenom i verkstadsindustrin?2003Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    Ända sedan den aktivitetsbaserade kalkyleringen (ABC) växte fram under 1980-talets slut har den lovordats av många författare och forskare. Den anses vida överlägsen den traditionella produktkalkyleringen som skapats på 1900-talets första hälft. Den traditionella produktkalkyleringen anses, med tanke på den utveckling som skedde under förra seklet, inte längre vara relevant i dagens företagsklimat. Trots detta visar studier i Sverige att mindre än en femtedel av företagen i verkstadsindustrin använder ABC-kalkyleringen

    MOTIVATION, PASSION OCH SJÄLVFÖRTROENDE HOS FOTBOLLSSPELARE I SVENSKA UNGDOMSLANDSLAG2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study was to investigate motivationalfactors, passionfactors and level of confidence players among the youth Swedish nationalteam in soccer. Furthermore the relationship between passion and confidence was investigated and also how motiovation is related to passion and confidence. 288 male and female soocer players aged between 15-17 (M=16.02, Sd=1.06) took part of the study. Vealey Sportconfidence Scale (VSS), Sport Motivation Scale (SMS) andThe Passion Scale (PS) was used in the study. The results showed statistically significant relationships between passion, motivation and confidence. The results showed that internal motivational factors was most common in youth national team players and that harmonic passion showed a more significant relationship with confidence than obsessive passion did. Further the results were analyzed and discussed in relation theories and earilier findings. Like all fields of research, further research on a wider population and with larger sample is needed in order to establish any form of conclusions.

    Chattering-Free Simulation for Hybrid Dynamical Systems: Semantics and Prototype Implementation2016In: 2016 IEEE Intl Conference on Computational Science and Engineering (CSE) and IEEE Intl Conference on Embedded and Ubiquitous Computing (EUC) and 15th Intl Symposium on Distributed Computing and Applications for Business Engineering (DCABES) / [ed] Randall Bilof, Los Alamitos: IEEE Computer Society, 2016, p. 412-422, article id 7982279Conference paper (Refereed)
    Abstract [en]

    Chattering is a fundamental phenomenon that is unique to hybrid systems, due to the complex interaction between discrete dynamics (in the form of discrete transitions) and continuous dynamics (in the form of time). In practice, simulating chattering hybrid systems is challenging in that simulation effectively halts near the chattering time point, as an infinite number of discrete transitions would need to be simulated. In this paper, formal conditions are provided for when the simulated models of hybrid systems display chattering behavior, and methods are proposed for avoiding chattering “on the fly” in runtime. We utilize dynamical behavior analysis to derive conditions for detecting chattering without enumeration of modes. We also present a new iterative algorithm to allow for solutions to be carried past the chattering point, and we show by a prototypical implementation how to generate the equivalent chattering-free dynamics internally by the simulator in the main simulation loop. The concepts are illustrated with examples throughout the paper. © 2016 IEEE.

    Kommunikation och kunskapsspridning via datoriserade medier2007Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Uppsatsen är ett resultat av en kvalitativ studie som undersöker hur wikis och bloggar

    förbättrar intern datoriserad kommunikation och kunskapsspridning i en IT-projektgrupp. Den kvalitativa studien genomfördes i form av personliga intervjuer med en projektledare och två systemutvecklare. Intervjuerna resulterade i empiriskt material rörande projektgruppens kommunikation och kunskapsspridning. Materialet jämfördes och analyserades mot den teoretiska referensramen och mynnade ut i ett antal slutsatser. Studien visar, bland annat, att wikis och bloggar gör information mer tillgänglig eftersom den dokumenteras på ett och samma ställe. Den enkla användningen och fria strukturen uppmuntrar också fler personer att bidra med sina idéer och tankar vilket leder till ökad delaktighet.

    Security issues with Mobile IP2011Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    With a rapid growth in wireless technology in recent years, Mobile IP has become very important for consumers and businesses by providing mobility based on IP addresses using several applications, which keep the employees connected with each others with critical information. In mobile IP the node can change its location by maintaining the same IP address and keep connected to the internet, which solves the issue of terminating the communication once it moves.

    Since Mobile IP uses open airwaves as a transmission medium, it is subject to the many security threats that are routed in mobile IP network .Protecting mobile IP from threats and attacks is one of the most challenging task now days. IPSec is a standard security protocol solution for TCP/IP network that provides security through Authentication, Encryption and data integrity services. Mobile IP data traffic can be secured by combining with IP Security (IPSec) protocol.

    This thesis describes Mobile IP operations, security threats, different existing methods for securing mobile IP and then IPSec standard, how it works and why IPSec is the best solution. This thesis also describes how to combine IPSec with a mobile IP to provide a solution called (SecMIP) that protects the mobile device’s communication from any threats. Finally it describes Mobile IPv6, binding update and associated security concern.

    Spectrum conversion in solar cells industry: Novel model concept and steps towards commercialization2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Solar photovoltaic industry is a hot research field, massive attempts are going on all over the world to increase its productivity in different ways. One of the challenges for solar cells is the light spectrum mismatch losses, which referred to the part of solar spectrum that cannot be utilized to electricity by the conventional cells.

    Two ways have been suggested to overcome solar spectrum mismatch losses, the first is multi layered cells (tandem cells) with a different light behavior for each layer, and the second is spectrum conversion which is this researches subject.

    Spectral modification or conversion in solar cells industry has been studied and different lab scale models have been introduced. According to nanoscale journal, such technology may be the base of the next generation solar cells, mentioning specifically the use of luminescence down conversion and up conversion techniques to control the light spectrum on the solar cell, these endeavors targets to produce solar cells that is not subjugated to Shockley-Queisser maximum efficiency limit of 31%.

    This research aims to draw a map of various ideas introduced to incorporate similar technologies in solar cell products, beside further suggestion to enhance its technical behavior and to push the commercialization of the technology forward. This is expected to reveal clear image about technology’s future development map for the upcoming studies, and to create a motivation for further studies towards a commercial production scale.

    The proposed commercialized model will result in enhancing the maximum theoretical efficiency limit to 48% if all spectral mismatch loses have been eliminated. Quantum energy level diagrams have been illustrated to describe each model’s performance under a theoretical light spectrum.

    Webbannonsering: Ett sätt att generera intäkter på Internet2006Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]
    I takt med att Internet breder ut sig över världen uppstår nya affärsmöjligheter för företag. Bland annat har en marknad utvecklats, bestående av företag som genererar sina intäkter genom att annonsera åt andra företag på sin hemsida. Syftet med denna uppsats är att undersöka vilka marknadsföringsåtgärder som företag skall tillämpa för att få Internetanvändare att besöka deras hemsida, samt hur denna hemsida ska vara utformad för att besökarna skall återkomma till den och styras vidare till andra hemsidor via annonser. En skrivbordsundersökning har gjorts där relevant teori, samt tidigare forskning tagits upp. Därefter genomfördes en kvantitativ studie där studenter fick svara på frågor angående deras Internetvanor. Studien visade bland annat att det är viktigt för företag att på ett effektivt sätt tillämpa SEO, Search Engine Optimation, som gör att hemsidor hamnar högre upp i sökmotorers träfflistor. Däremot är så kallade Popup-fönster överskattade. När det gäller hemsidans utformning, bekräftade studien de antagande som gjorts angående att det är viktigt att hemsidan är väl uppdaterad samt lätt att använda.

    Rosengårdens Barn och Den Svenska Kulturen2008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    This dissertation is about children in a district in Malmö, Sweden that is called Rosengård. This district is known for its high amount of immigrants and foreigners and all the children interviewed for the study are foreigners.

    We wanted to bring out their story, how they experience the cultures they are in touch with, the Swedish culture that they live in and their foreign culture that they experience at home with their parents. How do these children socialize into the Swedish culture while living in a district that is hardly exposed to it? We have been working from a different perspective, this due to the fact that we have both grown up in Rosengård and are still currently living here. Therefore our perspective is more from the inside, we can relate to the children’s stories and we can tell about it in a way that seems more natural.

    These children are not more different than other children, they have the same interests and hobbies as is considered to be “fashionable” in youth culture today. They all have hopes and dreams like everybody else, and the fact that they are not exposed to the Swedish culture does not seem to affect them, yet.

    Det permanenta projektet?: En teoriprövning utifrån det lokala utvecklingsavtalet i Halmstads kommun2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Flertalet av de bostadsområden, vilka vi idag kallar för ”utsatta”, uppkom som ett resultat av den bostadspolitik som tog sin början efter andra världskrigets slut och kan sägas ha nått sin kulm i det vi känner igen som miljonprogrammet. Målet med, den relativt nya, storstads- och den urbana politiken är att bryta mönster av det utanförskap som existerar inom dessa områden. Den senaste reinkarnationen av denna politik är det lokala utvecklingsavtalet (LUA). Kommuner ingår avtal med staten utifrån ett ramverk vilket säger att kommunerna åtager sig att genom samverkan och tvärsektoriella partnerskap arbeta med urbant utvecklingsarbete. Halmstads kommun har sedan år 2007 ingått ett lokalt utvecklingsavtal med staten för stadsdelen Andersberg. Detta fungerar som bakgrund till uppsatsen vars syfte är att pröva den s.k. vehikelteorin på det lokala utvecklingsavtalet i Halmstads kommun. Vehikelteorin säger att det lokala utvecklingsavtalet är ett sätt för staten att styra kommuner till att arbeta nätverksbaserat och tvärsektoriellt med urbant utvecklingsarbete. Uppsatsen vill med andra ord klargöra graden av nätverksbaserat och tvärsektoriellt utvecklingsarbete i Halmstads kommun, och framförallt utreda huruvida dessa samverkansformer och detta utvecklingsarbete är ett resultat av det lokala utvecklingsavtalet.

    Uppsatsens resultat visar att det inte finns belägg för att de samverkansformer som existerar inom utvecklingsarbetet är ett direkt resultat av det lokala utvecklingsavtalet. Vad som dock kan fastslås är att det lokala utvecklingsavtalet har inneburit en klar ökning av utvecklingsaktiviteter.

    Mittens rike: En idéanalys av Socialdemokraternas och Moderaternas idépolitik 1956-20092010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Inför årets riksdagsval så förekommer det en debatt där Sveriges två största politiska partier anklagas för att ha övergivit sina ideologiska värdegrund. Den rådande perceptionen är att detta har ledat till att de två partierna, Socialdemokraterna och Moderaterna, befinner sig närmare varandra än tidigare. Undersökningens syfte är att klargöra huruvida denna perceptions stämmer eller ej. Detta görs genom en idéanalys av de två partiernas idépolitik där partiprogram utgör material. Materialet ska klassificeras utefter olika idealtyper för att på så sätt kunna placera in partiernas idépolitiska position. Resultatet visar att den rådande perceptionen stämmer, Socialdemokraterna och Moderaterna befinner sig närmare varandra än tidigare. Detta är inte resultatet av att ett parti har närmat sig det andra, utan båda har gjort en idépolitisk resa i riktning mot den politiska mitten

    Ätstörningar: psykologisk störning eller samhälleligt problem?2003Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    Studien handlar om ätstörningar, varför kvinnor utvecklar den typen av sjukdom. Idag lever vi i ett utseendefixerat samhälle där vi dömer en individ efter utseendet istället för vem personen verkligen är. Ätstörningar är ett fenomen som blir allt vanligare bland oss. Det kan ses som en konsekvens av det moderna samhället vi lever i, där kraven på människorna ökar samtidigt som utbudet av mat och träningsinstitutioner blir allt större. Ätstörningar är inte bara en psykologisk störning utan utvecklas under miljöer som ger förutsättningar får sådan typ av sjukdom. Det finns inte endast en förklaring till varför kvinnor utvecklar den här typen av sjukdom. Slutsatsen är att ätstörningar är ett symptom på ett mer djupgående problem, där dåligt självförtroende spelar en central och avgörande roll.
