  • Attityder till naturvetenskap : Förändringar av flickors och pojkars attityder till biologi, fysik och kemi 1995 till 2007
  • 2011
  • swepub:Mat_licentiatethesis_t (swepub:level_scientificother_t)abstract
    • I den här avhandlingen beskrivs hur hög- och lågpresterande flickors och pojkars attityder till biologi, fysik och kemi har förändrats från 1995 till 2007. Data från den svenska delen av TIMSS-studierna för årskurs 8 i Sverige används. För att definiera hög- och lågpresterande används resultatet på matematikprovet från TIMSS och attityderna undersöks med hjälp av fyra frågor från elevenkäterna. Resultatet diskuteras utifrån olika perspektiv som kan bidra till förståelsen av den komplexa bilden av olika faktorers betydelse för elevers attityder till naturvetenskap. Det första resultatet, pojkar är mer positiva till fysik och kemi och flickor till biologi, diskuteras utifrån ämnenas genuskodning. På ett symboliskt plan är fysik och kemi mer förknippade med maskulinitet än biologi. Det andra resultatet, högpresterande elever och särskilt pojkar, är mindre positiva till de tre ämnena 2007 än 1995. Det resultatet diskuteras mot bakgrund av ungdomars identitet och identitetskonstruktion. Det verkar som om unga människor i dag inte tycker att utbildningar och arbeten inom det naturvetenskapliga och tekniska området ger dem möjligheter att använda sina talanger, kreativitet och självförverkligande. Resultatet diskuteras också utifrån de förändringar av arbetsmetoder som har skett i svensk skola där det individuella arbetet har ökat och lärarledda genomgångar har minskat. Kan det ha påverkat de högpresterande eleverna så att de har blivit mindre stimulerade och fått färre utmaningar och på så sätt blivit mindre positiva till de naturvetenskapliga ämnena? Det tredje resultatet, en större andel hög- och lågpresterande pojkar tycker att de tre ämnena är tråkiga 2007 jämfört med 1995, diskuteras utifrån begreppen "antipluggkultur" och att vara "cool". Kan resultatet från denna studie indikera att det är viktigare för pojkar 2007 att ha en attityd att visa sig ”cool” och att inte plugga. Kan detta ha påverkat attityderna till de naturvetenskapliga ämnena negativt? Slutligen visar resultaten att lågpresterande flickor och pojkar tycker att de presterar bättre 2007 än 1995 och det diskuteras mot bakgrund av förändringarna av arbetsmetoder i den svenska skolan. Mer tid ägnas åt individuellt arbete vilket kan innebära att de lågpresterande eleverna väljer att inte arbeta med svårare uppgifter och att de därför upplever att de presterar bättre. Avhandlingen avslutas med mina egna reflektioner kring undervisningen i de naturvetenskapliga ämnena i grundskolan, kring förändringarna av flickors och pojkars attityder till naturvetenskap utifrån resultaten från denna studie och kring mina erfarenheter som lärare i dessa ämnen.

  • Understanding regional renewal and industry cluster emergence processes within the Swedish periphery
  • 2010
  • swepub:Mat_licentiatethesis_t (swepub:level_scientificother_t)abstract
    • There are many insightful writings revealing that regions within industrialised nations are able to renew their local business environments through building and supporting industry clusters. Such knowledge stems from research based on how to maintain and develop successful industry clusters located within central regions. Although such knowledge is valuable for both researchers and practitioners, little is known about the processes involved when new industry clusters are emerging; and especially when they are emerging in peripheral regions. To that background, the purpose of this licentiate thesis is to develop further understanding of regional renewal and industry cluster emergence within peripheral regions. The thesis is based on a series of covering chapters and three research papers. Each of the three research papers contributes to the aim of this study and the research questions that are brought forward within the covering chapters. With aims of developing theory and providing empirical illustration of regional renewal and industry cluster emergence the research questions used to guide this particular research are: How does a new industry cluster emerge within a peripheral region and what are the main processes involved? What role does the interaction between new regional industry and established regional industry play in facilitating industry cluster emergence? What core co-operative and competitive forces drive such emergence efforts? Relevant empirical material brought forward to help answer these questions is based stems from within the peripheral Swedish county of Västernorrland and specifically centres on the emergence of a new biorefinery industry cluster in the Örnsköldsvik region. A conceptual framework outlining structural-organisational, socio-institutional and cognitive perspectives of regional renewal is employed to help govern the study and aid discussion of the three individual research papers appended. Overall, and in a very condensed format, the papers related to this licentiate thesis reveal that industry cluster emergence within a peripheral region can be supported by bottom-up efforts that encapsulate social movement framing activities, dialectical interplays as well as regional competitive and co-operative forces. In particular, interactions between new regional industry and established industry entities can play a key role in the process; mainly through established actors responding to local resource and legitimacy threats that have potential to reduce the region’s opportunities for renewal. Moreover, new industry actors’ mobilisations provide an ‘anti-thesis’ to local traditional industry that restrain but also trigger development. This is found to be crucial to overcome traditional regional actors’ contestation to new industry entities. As such it seems a set of core processes that interact and shape regional industry cluster emergence can be categorised and described as framing processes, movement mobilisation processes, inter-industry relational processes and dialectical processes. Furthermore prominent regional competitive and competitive forces driving industry cluster emergence are revealed to be intra and inter-regional. Those forces can have strong implications for regional renewal in the periphery. As this research focuses upon how a new regional industry cluster can emerge within a peripheral region dominated by declining traditional industries, that is able, but not without difficulties, to aid regional renewal the thesis contributes to further theoretical and practical understanding of regional renewal and industry cluster emergence theories. Thus, offering relevant implications for future researchers, regional policy makers and industry cluster developers interested in peripheral regional development issues.

  • Från student till yrkesverksam polis - mental träning i polisutbildningen och polisyrket : Polisstudenters och yrkesverksamma polisers upplevda kompetens i mental träning
  • 2010
  • swepub:Mat_licentiatethesis_t (swepub:level_scientificother_t)abstract
    • This study is about police students’ and professional police officers’ experienced competence in mental preparation training. The aim with the study is to compare how police students’ in the beginning and in the end of the Basic Training Programme for Police Officers perceive their competence in mental preparation training and how a selection of these students perceive their competence after one respectively two and a half year as police officers. The aim is also to compare the formal competence required of students who have passed the Basic Training Programme for Police Officers with the competence students actually think they have, and the formal competence required within the police profession with the competence police officers with differently long time as professionals experience that they have. Moreover the study includes a comparison between the formal and experienced competence in the Basic Training Programme for Police Officers and in the police profession. The empirical data of the study is based on a web questionnaire to the different groups of students and follow-up interviews with a selection of these students. The results show that the students’ perceived competence increases during the Basic Training Programme and that the experienced competence at the end of the programme to a relatively large extent corresponds to the formal competence of the programme. The difference between the formal competence required in the police profession and the police officers’ experienced competence is relatively small. The police officers’ experience though is that their competence in mental preparation training is not requested in the profession to any larger extent. Key words: Police, competence, mental preparation training.

  • Transcriptional regulation of mouse ribonucleotide reductase
  • 2011
  • swepub:Mat_licentiatethesis_t (swepub:level_scientificother_t)abstract
    • All living organisms are made of cells and they store their hereditary information in the form of double stranded DNA. In all organisms DNA replication and repair is essential for cell division and cell survival. These processes require deoxyribonucleotides (dNTPs), the building blocks of DNA. Ribonucleotide reductase (RNR) is catalyzing the rate limiting step in the de novo synthesis of dNTPs. Active RNR is a heterodimeric protein complex. In S phase cells, the mouse RNR consists of the R1 and the R2 proteins. The R1/R2 RNR-complex supplies the cell with dNTPs required for DNA replication. Outside S-phase or in non-proliferating cells RNR is composed of R1 and p53R2 proteins. The R1/p53R2 RNR-complex supplies cells with dNTPs required for mitochondrial DNA replication and for DNA repair. An undisturbed dNTP regulation is important since unbalanced dNTP pools results in DNA mutations and cell death. Since unbalanced pools are harmful to the cell, RNR activity is regulated at many levels. The aim of this thesis is to study how the mouse RNR genes are regulated at a transcriptional level. We have focused on the promoter regions of all three mouse RNR genes. Primer extension experiments show that the transcription start of the TATA-less p53R2 promoter colocalizes with an earlier unidentified initiator element (Inr-element). This element is similar to the known Inr-element in the mouse R1 promoter. Furthermore, functional studies of the R1 promoter revealed a putative E2F binding element. This result suggests that the S phase specific transcription of the R1 gene is regulated by a similar mechanism as the R2 promoter which contains an E2F binding site. Finally we have established a method to partially purify the transcription factor(s) binding the upstream activating region in the mouse R2 promoter by phosphocellulose chromatography and affinity purification using oligonucleotides immobilized on magnetic beads. This method will allow us to further study the transcription factors responsible for activating expression of the R2 protein. This method has a potential to be utilized as a general method when purifying unknown transcription factors.

  • Metadata Management in Multi-Grids and Multi-Clouds
  • 2011
  • swepub:Mat_licentiatethesis_t (swepub:level_scientificother_t)abstract
    • Grid computing and cloud computing are two related paradigms used to access and use vast amounts of computational resources. The resources are often owned and managed by a third party, relieving the users from the costs and burdens of acquiring and managing a considerably large infrastructure themselves. Commonly, the resources are either contributed by different stakeholders participating in shared projects (grids), or owned and managed by a single entity and made available to its users with charging based on actual resource consumption (clouds). Individual grid or cloud sites can form collaborations with other sites, giving each site access to more resources that can be used to execute tasks submitted by users. There are several different models of collaborations between sites, each suitable for different scenarios and each posing additional requirements on the underlying technologies.Metadata concerning the status and resource consumption of tasks are created during the execution of the task on the infrastructure. This metadata is used as the primary input in many core management processes, e.g., as a base for accounting and billing, as input when prioritizing and placing incoming task, and as a base for managing the amount of resources allocated to different tasks.Focusing on management and utilization of metadata, this thesis contributes to a better understanding of the requirements and challenges imposed by different collaboration models in both grids and clouds. The underlying design criteria and resulting architectures of several software systems are presented in detail. Each system addresses different challenges imposed by cross-site grid and cloud architectures:The LUTSfed approach provides a lean and optional mechanism for filtering and management of usage data between grid or cloud sites.An accounting and billing system natively designed to support cross-site clouds demonstrates usage data management despite unknown placement and dynamic task resource allocation.The FSGrid system enables fairshare job prioritization across different grid sites, mitigating the problems of heterogeneous scheduling software and local management policies.The results and experiences from these systems are both theoretical and practical, as full scale implementations of each system has been developed and analyzed as a part of this work. Early theoretical work on structure-based service management forms a foundation for future work on structured-aware service placement in cross- site clouds.

  • Glomerular filtration rate in adults : a single sample plasma clearance method based on the mean sojurn time
  • 2011
  • swepub:Mat_licentiatethesis_t (swepub:level_scientificother_t)abstract
    • Glomerular filtration rate (GFR) is a key parameter in evaluating kidney function. After a bolus injection of an exogenous GFR marker in plasma an accurate determination of GFR can be made by measuring the marker concentration in plasma during the excretion. Simplified methods have been developed to reduce the number of plasma samples needed and yet still maintain a high accuracy in the GFR determination. Groth previously developed a single sample GFR method based on the mean sojourn time of a GFR marker in its distribution volume. This method applied in adults using the marker 99m Tc-DTPA is recommended for use when GFR is estimated to be ≥ 30 mL/min. The aim of the present study was to further develop the single plasma sample GFR method by Groth including patients with severely reduced renal function and different GFR markers. Three different GFR markers 51Cr-EDTA, 99mTc-DTPA and iohexol were investigated. Formulas were derived for the markers 51Cr-EDTA and iohexol when GFR is estimated to be ≥ 30 mL/min. For patients with an estimated GFR < 30 mL/min a special low clearance formula with a single sample obtained about 24 h after marker injection was developed. The low clearance formula was proven valid for use with all three markers. The sources of errors and their influence on the calculated single sample clearance were investigated. The estimated distribution volume is the major source of error but its influence can be reduced by choosing a suitable sampling time. The optimal time depends on the level of GFR; the lower GFR the later the single sample should be obtained. For practical purpose a 270 min sample is recommended when estimated GFR ≥ 30 mL/min and a 24 h sample when estimated GFR < 30 mL/min. Sampling at 180 min after marker injection may be considered if GFR is estimated to be essentially normal.

  • Generalised linear models with clustered data
  • 2010
  • swepub:Mat_licentiatethesis_t (swepub:level_scientificother_t)abstract
    • In situations where a large data set is partitioned into many relativelysmall clusters, and where the members within a cluster have some common unmeasured characteristics, the number of parameters requiring estimation tends to increase with sample size if a fixed effects model is applied. This fact causes the assumptions underlying asymptotic results to be violated. The first paper in this thesis considers two possible solutions to this problem, a random intercepts model and a fixed effects model, where asymptoticsare replaced by a simple form of bootstrapping. A profiling approach is introduced in the fixed effects case, which makes it computationally efficient even with a huge number of clusters. The grouping effect is mainly seen as a nuisance in this paper. In the second paper the effect of misspecifying the distribution of the random effects in a generalised linear mixed model for binary data is studied. One problem with mixed effects models is that the distributional assumptions about the random effects are not easily checked from real data. Models with Gaussian, logistic and Cauchy distributional assumptions are used for parameter estimation on data simulated using the same three distributions. The effect of these assumptions on parameter estimation is presented. Two criteria for model selection are investigated, the Akaike information criterion and a criterion based on a chi-square statistic. The estimators for fixed effects parameters are quite robust against misspecification of the random effects distribution, at least with the distributions used in this paper. Even when the true random effects distribution is Cauchy, models assuming a Gaussian or a logistic distribution regularly produce estimates with less bias.

  • Swedish trade and trade policies towards Lebanon 1920-1965
  • 2011
  • swepub:Mat_licentiatethesis_t (swepub:level_scientificother_t)abstract
    • This licentiate thesis examines the development of Swedish–Lebanese trade relations and the changes of significance for Swedish trade towards Lebanon during the period 1920-1965. The aim of the study is to explore how Sweden as representing a small, open Western economy could develop its economic interests in the emerging Middle East market characterised both by promising economic outlooks, and a high degree of political instability during the age of decolonisation, Cold War logic, and intricate commercial and geo-political factors. The study shows that the Swedish trade with Lebanon was very small during the Interwar period. It was neither possible to find any formal Swedish-Lebanese trade agreements before 1945. In the Post-War period, the promotion of Swedish trade and trade policies towards Lebanon witnessed more interests from the both parties. Two categories of explanations were found for the periods of 1946-53 and 1954-65 respectively. In the first period the Swedish-Lebanese trade developed in a traditional direction with manufactured goods being exported from Sweden and agricultural products being exported from Lebanon. Furthermore, there were no trade agreements between the two countries. In the second period, several Lebanese attempts were made to conclude bilateral trade agreement with Sweden in hope to change the traditional trade direction, and to improve the Lebanese balance of trade. Sweden was, however, convinced that Lebanon could never achieve a balanced foreign trade at least not on a bilateral basis. To maintain a fair access to the Lebanese market, the Swedish authorities avoided to conclude any trade agreement with Lebanon. Despite the Lebanese concern on the big trade deficit between the two countries, Sweden managed in increasing the trade volumes to the region of Middle East through the transit link of Lebanon.
