    Calcium sulphate spinal cord scaffold: a study on degradation and fibroblast growth factor 1 loading and release2012In: Journal of biomaterials applications, ISSN 0885-3282, E-ISSN 1530-8022, Vol. 26, no 6, p. 667-685Article in journal (Refereed)
    Abstract [en]

    Currently, there is no regenerative strategy for the spinal cord that is part of clinical standard of core. Current paths usually include combinations of scaffold materials and active molecules. In a recent study, a permanent dental resin scaffold for treatment of spinal cord injury was designed. The results from studies on rats were promising. However, for potential clinical use, a biodegradable scaffold material that facilitates drug delivery and the regeneration of the spinal cord needs to be developed. Also a biodegradable material is expected to allow a better evaluation of the efficacy of the surgical method. In this article, the suitability of hardened calcium sulfate cement (CSC) for use as degradable spinal cord scaffolds is investigated in bench studies and in vitro studies. Compressive strength, degradation and microstructure, and the loading capability of heparin-activated fibroblast growth factor 1 (FGF1) via soaking were evaluated. The CSC could easily be injected into the scaffold mold and the obtained scaffolds had sufficient strength to endure the loads applied during surgery. When hardened, the CSC formed a porous microstructure suitable for loading of active substances. It was shown that 10 min of FGF1 soaking was enough to obtain a sustained active FGF1 release for 20–35 days. The results showed that CSC is a promising material for spinal cord scaffold fabrication, since it is biodegradable, has sufficient strength, and allows loading and controlled release of active FGF1.

    An On-site Industrial Experimental Heat Flux Study during Solidification of Pure Copper in the Southwire Process2007In: T INDIAN I METALS, ISSN 0972-2815, Vol. 60, no 2-3, p. 191-196Article in journal (Refereed)
    Abstract [en]

    To study the production of pure copper and copper alloys in the Southwire process the temperature in the mould has been measured on-site in the production process in a number of positions. To increase the accuracy and robustness of measurements a new type of thermocouple based temperature sensor has been developed and tested. The test system includes wireless transmission of measured data from the moving mould. The results from the measurements are then used to calculate the energy transfer rate from the solidifying shell as a function of time. An initial in-situ measurement campaign has been performed and the results are very promising.

    Biocompatibility and resorption of a radiopaque premixed calcium phosphate cement2012In: Journal of Biomedical Materials Research. Part A, ISSN 1549-3296, E-ISSN 1552-4965, Vol. 100A, no 5, p. 1269-1278Article in journal (Refereed)
    Abstract [en]

    Calcium phosphate cements (CPC) are used as bone void filler in various orthopedic indications; however, there are some major drawbacks regarding mixing, transfer, and injection of traditional CPC. By using glycerol as mixing liquid, a premixed calcium phosphate cement (pCPC), some of these difficulties can be overcome. In the treatment of vertebral fractures the handling characteristics need to be excellent including a high radio-opacity for optimal control during injection. The aim of this study is to evaluate a radiopaque pCPC regarding its resorption behavior and biocompatibility in vivo. pCPC and a water-based CPC were injected into a circle divide 4-mm drilled femur defect in rabbits. The rabbits were sacrificed after 2 and 12 weeks. Cross sections of the defects were evaluated using histology, electron microscopy, and immunohistochemical analysis. Signs of inflammation were evaluated both locally and systemically. The results showed a higher bone formation in the pCPC compared to the water-based CPC after 2 weeks by expression of RUNX-2. After 12 weeks most of the cement had been resorbed in both groups. Both materials were considered to have a high biocompatibility since no marked immunological response was induced and extensive bone ingrowth was observed. The conclusion from the study was that pCPC with ZrO2 radiopacifier is a promising alternative regarding bone replacement material and may be suggested for treatment of, for example, vertebral fractures based on its high biocompatibility, fast bone ingrowth, and good handling properties.

    In vitro and in vivo evaluation of an injectable premixed calcium phosphate cement: cell viability and immunological response from rat2010In: International Journal of Nano and Biomaterials, ISSN 1752-8941Article in journal (Refereed)
    Abstract [en]

    By using premixed calcium phosphate cement (CPC) the handling properties of the cement are drastically improved, which is a challenge for traditional injectable CPC. In this article, a premixed acidic CPC has been compared to a conventional water mixed brushite cement to evaluate whether the premixed concept affects the biological response. The cements were evaluated regarding the pH-variation in simulated body fluid (SBF). Further, the biocompatibility of the cement with human mesenchymal stem cells (MSC) was studied in vitro and eventual inflammation properties studied in vivo, after subcutaneous material injections in rats. A larger pH decrease was seen for the conventional cement than the premixed cement in SBF. For both materials, > 90% of the MSC remained alive in vitro. No systemic or macroscopic inflammation was detected, only a mild microscopic inflammation was detected around both materials. In addition to the handling benefit of premixed cements compared to conventional water mixed CPC, the premixed CPC in the present study demonstrated high and in comparison to conventional CPC comparable biocompability, both in vitro and in vivo.

    Modelling of Thermal Stresses in Industrial Continuous Casting Processes2005In: Proceedings of the Femlab Conference, Stockholm, 2005Conference paper (Refereed)
    Abstract [en]

    This paper reports on progress in the implementationof COMSOL Multiphysics 3.2 to model thermalstresses in a three-dimensional solidifying shell, asoccurs typically in the industrial continuous casting ofcopper, copper alloys and steel. Computer memory requirementsprohibit a direct 3D numerical simulation ofthe temperature and the stresses. Instead, we use the factthat casting geometries are usually slender to divide thecalculation into three steps that are each less memoryintensive:(i) heat transfer and solidification is simulatedusing an arbitrary Lagrangian-Eulerian model; (ii) thetemperature solution is used to solve the force equilibriumequations in generalised plane strain mode appropriatefor a moving body; (iii) this solution is used tocompute the accumulated stress and strain in the body.Comparison between an analytical solution and a numericalsolution, that requires the simultaneous use ofseveral of Comsol Multiphysics’ peripheral features, ispresented.

    An on-site experimental heat flux study and its interpretation in a FEMLAB finite element simulation of continuous casting of copper in the South-Wire process2005In: Transactions of the Indian Institute of Metals, ISSN 0019-493X, Vol. 58, no 4, p. 509-515Article in journal (Refereed)
    Abstract [en]

    The South-Wire process, a development of the Properzi process, to continuously cast copper has been studied both experimentally and by finite element computer simulation. The experimental work has been performed on site to get temperature data as a function of time at several locations within the mould. These experimental data have been used to evaluate boundary conditions for the heat transfer from the strand-mould interface and through the mould. A simulation model of the casting process has been developed in the program FEMLAB. In this program temperature varying material data and time varying boundary conditions have been used. The simulation model has been verified by comparing with an analytical solution, and then applied to the real physical process.

    Uniaxial material damping measurements using a fiber optic lattice: a discussion of its performance envelope2004In: Experimental mechanics, ISSN 0014-4851, E-ISSN 1741-2765, Vol. 44, no 1, p. 33-36Article in journal (Refereed)
    Abstract [en]

    Damping is the internal transfer of kinetic energy to other forms of energy. Today, most methods use either bending or torsional vibration to measure damping. This means that the strain field in the specimen is nonhomogeneous. If the damping of the tested material is linear, strain-independent, the values acquired with these traditional methods will be equal to the intrinsic material damping of the material. If, however, the damping is strain-dependent, nonlinear, the measured value will be an average of the damping of the specimen, and not equal to its intrinsic material damping. To address this problem, a method is required to experimentally determine the damping in uniaxial tension in order to produce the same strain level in all parts of the test specimen and hence obtain a measurement of the intrinsic material damping. Using such a method, it is possible to view the material damping as the phase angle between the stress and the strain in a harmonic oscillation. In this paper, a method is suggested for measuring this phase shift in uniaxial tension to determine the material damping properties. It uses a tensile test machine, an optical fiber Bragg grating technique and a lock-in amplifier. Measurements with the phase shift technique have been suggested previously, but its performance envelope has been overestimated. In this paper, the performance envelope is discussed and restricted. It is shown that the envelope depends on the specimen length, loss factor and test frequency. An optical strain measurement method is also believed to help avoid many electrical measurement problems seen with the originally proposed method.

    Measurement of intrinsic material damping using differential calorimetry on specimens under uniaxial tension2004In: Thermochimica Acta, ISSN 0040-6031, E-ISSN 1872-762X, Vol. 411, no 2, p. 125-131Article in journal (Refereed)
    Abstract [en]

    A method has been developed to measure the intrinsic damping capacity of metals. A specimen is subjected to a cyclic uniaxial stress, to give a prescribed energy input. The amount of energy that is stored in the specimen is measured using differential calorimetry, i.e. the difference in temperature between the specimen under stress and a non-stressed reference sample is measured. The experiments were performed in an insulated vacuum container to reduce convective losses. The heating rate, together with the energy input, is used as a measure of the intrinsic material damping in the specimen. The method has been developed by testing an aluminium based and a stainless steel alloy. It is possible to distinguish the difference in damping between these two alloys.

    "Ju bättre vi känner det förflutna, desto bättre kan vi förutse framtiden": En enfallsstudie kring hur den tekniska utvecklingen påverkat redovisningskonsulten som profession inom en tidsram på 40 år.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background and problem discussion: The technological development, including automation and digitalization, is constantly present today. New programs and systems are introduced and developed daily, and these are increasingly taking over human tasks. This phenomenon is affecting the accounting consultant. But how has the technological development affected the accounting consultant as a profession until today? The starting point of the study is 1976, the year when the standard for the swedish chart of accounts was introduced as a consequence of the technological development impact on the profession.

    Objective: The purpose of this thesis is to contribute with deep knowledge about the impact of the technological development on the accounting consultant as a profession in the past 40 years. This essay will present the trend which has characterized the accounting consultant’s work tasks during the chosen time period, then linking to why this has been done based on different theories. Furthermore, this is linked to professional theory that contributes with knowledge regarding how the profession has changed. In this study, some speculations will also be drawn about how the profession will be developed in the future.

    Method: The essay is constructed as a case study. Five semi-structured interviews have been used as a primary source to collect information. These interviews are combined with the journal Balans which has been used as a secondary source.

    Conclusion: Almost all tasks that are related to the accounting consultant have changed. Today the computers and systems can fulfill these tasks almost all by themselves. The changes of the tasks have led to a reduction in the jurisdiction of the accounting consultant. Finally, the changed jurisdiction lead to a change of the profession. The technological development has only affected the profession by transforming the types of services that exist within its scope, this because expertise has been transferred to commodities.

    Kan det vara för evigt?: En kvalitativ studie av det ökade skilsmässotalets upplevda påverkan på individers attityd till långa parrelationer2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to examine if individuals feel that increased divorce rates impact their attitude towards long-term relationships. The empirical data was collected through semi-structured interviews with four young women who shared their thoughts and feelings about marriage, relationships and divorces. The study is based on theories about reflexive modernity and individualization (see Beck, Beck-Gernsheim and Giddens). The empirical data is also analyzed by Giddens’ theory of the pure relationship and his theory about the ontological security. The theory of socialization is also used along with Bourdieu’s concept of habitus.

    The result of the study shows that individuals with divorced parents are aware of the increased divorce rates in society and that it affects their attitude to long-term relationships. This can be explained primarily by using the theory of socialization and the concept of habitus. The respondent in the study whose parents still lived together considered herself protected from the increased divorce rates and experienced therefore that this did not affect her attitude to long-term relationships. The more thorough analysis nevertheless shows that all respondents are affected by the increased divorce rates in society, even if the respondent with non-divorced parents was not aware of it herself. The increased individualism and modern societies reflexive nature can explain this. This result appeared even though the study in advance did not intend to distinguish between individuals who have been through a parental divorce and individuals who have not.

    Abstract [en]

    The aim of my study is to look at two specific schools and their work with Internet in the classroom and compare their work to what experts say about how you should educate. The study focuses on how teachers guide the students to be critical to the information they encounter on the internet. What do the experts say? How should the teachers work with Internet in the classroom? What do the teachers say about their work with Internet? What do the teachers say regarding children and the Internet?  To answer these questions I have interviewed two teachers from different schools, which had classes with children 6 to 8 years old. The schools are very different from each other concerning investment on Internet devices in the classroom. I have also interviewed two experts on the subject who are working for organisations concerned with children’s use of the Internet.

    I have related my findings to older research, Marc Prensky’s terms Digital Natives and Digital Immigrant are frequently used in the study. I found that the work with and understanding of Internet depended on what generation the teacher belonged to. Older teachers are Digital Immigrants while the younger teachers are Digital Natives who have been brought up with digital media. According to Prensky and other experts it’s important that teachers learn to communicate in the style of their students, and give Internet a place in the classroom. Children are spending much time on the Internet and it’s important, according to the experts, to guide the children and learn them to be critical to the information they come across.

    Matematiska symboler och matematikuppgifters svårighetsgrad2011Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att fördjupa förståelsen för eventuella samband mellan förekomst av matematiska symboler och matematikuppgifters svårighetsgrad. I studien har matematikuppgifter från PISA 2003 och Nationella prov i matematik A, B och C på gymnasiet analyserats utifrån vilka typer av matematiska symboler de innehåller. Resultatet av denna analys har sedan med hjälp av statistisk korrelationsanalys jämförts med uppgifternas lösningsfrekvenser samt hur höga krav på läsförmåga uppgiften ställer. Studiens resultat visar att sambanden mellan förekomst av olika symboltyper och dess lösningsfrekvenser är för svaga för att någon definitiv slutsats ska kunna dras. Korrelationsanalysen visar dock att ett något starkare samband finns mellan förekomsten av bokstavssymboler i matematikuppgifter och låga lösningsfrekvenser än för någon av de andra symboltyperna. När förekomsten av olika symboltyper jämförs med hur höga krav uppgiften ställer på läsförmåga finns det inget som tyder på att förekomsten av olika symboltyper har något samband med hur höga krav på läsförmåga en uppgift ställer.

                                          How loyal are the consumers to the brand Lohmanders?

                                          How does brand loyalty arise among Lohmanders customers?

    Purpose:                            The purpose with this thesis is to research consumer’s brand loyalty to fresh sauce and to analyze how brand loyalty arises regarding the brand Lohmanders.

    Method:                       The theoretical framework used in the study is based on theories of consumer behavior, brands and loyalty. The quantitative study consists of a poll. To complement the study a focus group interview and a company interview have been held. 

     

    Conclusion:                        The study showed that the brand has significance for the consumer to a certain extent. The brand can though have an unconscious effect on the consumers since most of the purchases are made by habit.   It can be difficult for Lohmanders to achieve brand loyalty in which the consumer are actively involved and have a strong conscious sense for the brand. However, Lohmanders can through positive associations to the brand and brand awareness get the consumer to buy the product by habit and thereby achieve loyalty.

    Warranty reserve forecast for complex products2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Warranty is a contract between a seller and a buyer. A warranty is also a signal for quality that can be

    utilized both by the seller and the customer. Even though the warranty is mainly something that is

    positive, a warranty also incurs risk to the warranty provider. The warranty cost can range from 2 -

    15% of the net sales of a product which means that the warranty cost could potentially affect the

    company a lot. In order to handle such a risk, forecasting is a necessary tool. Forecasting is no exact

    science, and it’s impossible to forecast the exact future value due to uncertainty. Factors such as the

    quality of the product affect the cost of the claims, but unpredictable factors such as fraud, human

    factors and sales delay must also be considered. Forecasting error affects the warranty provider

    because the forecast sets the warranty reserve, which should cover the costs of the warranty claims.

    Overestimations and underestimations of the reserve have negative consequences for the company.

    The purpose of this study is to forecast a warranty reserve using a quantitative approach, in order to

    gain insight in to which model that could be best suited for complex products. The models that have

    been tested originate from causal and time-series methods, where the models tested consider different

    aspects of the data. The primary data used comes from archive data and to determine the forecast

    error, error measurements have been utilized. The time series method exponential smoothing Holt’s-

    Winter’s method was the one that performed best considering the error measurements. From the

    models tested, it has been shown that a more complex model does not necessarily mean a more

    accurate result. To be able to decrease the forecasting errors, a model considering unpredictable

    factors such as fraud could be the answer which makes it interesting to investigate.

    Strategic Outsourcing in the Pharmaceutical Industry: A Transaction Cost Analysis2002Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The key question in this essay is about strategic outsourcing in the pharmaceutical industry, discussed from a transaction cost perspective. The authors have chosen to carry out this research according to the case study theory suggested by Gummesson and others. A representative for a large pharmaceutical company, AstraZeneca, and a representative for small entrepreneurial companies, Karolinska Innovations AB (KIAB), were chosen as case studies. These two companies were completed by interviewing a major player in the outsourcing market, Quintiles AB, to be able to look at the type of relationship between buyer and seller. In summary, smaller companies need to outsource a large amount of it’s production due to its financial limitations, which is also the recommendation according to the theory. Larger companies like AstraZeneca should choose outsourcing and at the same time lengthen the duration of the outsourced projects. A outsourcing ratio of 30%, which is the policy of AstraZeneca, seems to be the right approach in the decision between outsourcing and production inside. Early research in drugs, though, will not be outsourced because of the strategic implication. In terms of type of contract, our research has shown that a move from the pure buyer/seller-relationship towards a preferred supplier or even a strategic supplier alliance is recommended.

    Variance Reduction in Analytical Chemistry: New Numerical Methods in Chemometrics and Molecular Simulation2004Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is based on five papers addressing variance reduction in different ways. The papers have in common that they all present new numerical methods.

    Paper I investigates quantitative structure-retention relationships from an image processing perspective, using an artificial neural network to preprocess three-dimensional structural descriptions of the studied steroid molecules.

    Paper II presents a new method for computing free energies. Free energy is the quantity that determines chemical equilibria and partition coefficients. The proposed method may be used for estimating, e.g., chromatographic retention without performing experiments.

    Two papers (III and IV) deal with correcting deviations from bilinearity by so-called peak alignment. Bilinearity is a theoretical assumption about the distribution of instrumental data that is often violated by measured data. Deviations from bilinearity lead to increased variance, both in the data and in inferences from the data, unless invariance to the deviations is built into the model, e.g., by the use of the method proposed in paper III and extended in paper IV.

    Paper V addresses a generic problem in classification; namely, how to measure the goodness of different data representations, so that the best classifier may be constructed.

    Variance reduction is one of the pillars on which analytical chemistry rests. This thesis considers two aspects on variance reduction: before and after experiments are performed. Before experimenting, theoretical predictions of experimental outcomes may be used to direct which experiments to perform, and how to perform them (papers I and II). After experiments are performed, the variance of inferences from the measured data are affected by the method of data analysis (papers III-V).

    Extensions to peak alignment using reduced set mapping and classification of LC-UV data from peptide mapping2005In: Journal of Chemometrics, ISSN 0886-9383, E-ISSN 1099-128X, Vol. 18, no 10, p. 465-473Article in journal (Refereed)
    Abstract [en]

    Peak alignment using reduced set mapping (PARS) is extended with a new baseline approximation

    and a new dendrogram alignment scheme, which is designed to avoid the issue of selecting a target

    chromatogram for the alignment. Two data sets with LC/UV data are studied and it is shown that

    peak alignment with PARS increases the class separation substantially in the principal component

    score space. The results indicate that it is possible to use PARS for calibration transfer of multivariate

    models of chromatographic data.

    "Anyone could do that": Nordic perspectives on competence in tourism2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In academic reasoning, as well as policy rhethoric, much attention has been drawn to the low thresholds to employment and entrepreneurship in tourism. The purpose of this thesis is to go beyond the simplified images and examine the educational characteristics of the tourism workforce in a way that includes both a geographical and work task related aspect. By employing a sequential mix of methods, two perspectives on competence in tourism are presented. First, the actual presence of formal education within the workforce is mapped and discussed based on descriptive analyses of register data. Thereafter, thematic analyses of interviews are used to allow for a discussion on underlying reasoning of recruitment. The theoretical point of departure is that the workforce is a crucial input factor of the production process in labour intense service sectors such as tourism. However, the access to a suitable workforce differs between destinations. It is therefore imperative to scrutinize its characteristics in order to set relevant strategies for development, as well as education.

    The thesis contains four individual papers and an introductory section. The first two papers are based on register data on the Swedish national workforce in the years 2000, 2005 and 2010. The results show that the general level of formal education is not exceptionally low in tourism and that it is rather linked to geography than occupational sector. There was also confirmed to be a mismatch between tourism-specific education and work in tourism. In the second part of the thesis, focus is turned to the managerial segment within destination development. The geographical scope includes the northern region of Sweden and one case study area each in Norway and Finland. The empirical material shows that tourism-specific education was not prioritized when recruiting for destination management.

    The empirical findings are brought together in the concluding discussion of the thesis. It is there suggested that reasoning on the educational characteristics of the tourism workforce needs to  include the diversity of local preconditions and needs relating to geography and work tasks.

    The importance of being local: prioritizing knowledge in recruitment for destination development2014In: Tourism Review, ISSN 1660-5373, E-ISSN 1759-8451, Vol. 69, no 3, p. 229-243Article in journal (Refereed)
    Abstract [en]

    Purpose: The paper aims to illuminate the discrepancy between the need for knowledge as found in prior research and the requirements formulated by those taking part in destination development. The results are intended to contribute to further research on the role of knowledge in destination management when performed as a strategy for regional development.

    Design/methodology/approach: Based on theories within epistemology and tourism, an interview structure was developed and used in 10 in-depth interviews, with a qualitative approach through open-ended questions. This was complemented by a mapping of specific background factors through enquiries with 23 respondents. The paper follows an explorative approach to illuminate one aspect within the research area of destination development.

    Findings: It was found that when recruiting much significance is put on understanding the structures of involved actors and local rooting. In contrast to theoretical findings, specific knowledge was not a prioritized requirement, neither in tourism nor marketing. Hence, there is a gap between what is perceived as needed for destination development according to academia and how it is being performed by practitioners.

    Research limitations/implications: The study is limited in geography and context. Because the research design was showed to be successful in capturing significant aspects, it is proposed for use in further research.

    Practical implications: The paper deepens the understanding of factors explaining success and impediments of destination development. It underlines the need for bridging the gap between theory and practice.

    Originality/value: This work addresses a vital, but not fully explored, aspect of an extensively implemented strategy for regional development.

    The development of geographical differences in education levels within the Swedish tourism industry2018In: Tourism Geographies, ISSN 1461-6688, E-ISSN 1470-1340, Vol. 20, no S1, p. 67-84Article in journal (Refereed)
    Abstract [en]

    The nexus of workforce and destination development is a largely uncharted area within tourism research. The local human capital has above all been in focus when underlining tourism’s potential to create employment even for the inexperienced and less educated. However, a discordant strand of theory holds the low levels of qualified knowledge within the industry responsible for absent destination development in areas struggling to develop competitive advantages. Additionally, the in-migration of a skilled workforce may be hampered by a lack of amenities attracting permanent residents. In order to explore whether the tourism sector is characterized by a less educated share of the workforce, a study was performed using micro-level data on the full working population of Sweden during the years 2000–2010. The workforce in tourism was compared to the total and two other low-skill sectors, and the results show that the educational aspects within tourism are more related to geography than economic sectors. Contrary to general presumptions, the workforce within the tourism sector has a higher level of formal education than the other selected sectors in regions with generally low educational levels. The implication is thus that strategies aimed at creating employment for the least educated in rural areas need to be reconsidered, and not unconditionally target the tourism sector. Above all, tourism development needs to be based on assessments of local preconditions rather than a generalized image.

    Destination development in Ostrobothnia: great expectations of less involvement2018In: Scandinavian Journal of Hospitality and Tourism, ISSN 1502-2250, E-ISSN 1502-2269, p. S7-S23Article in journal (Refereed)
    Abstract [en]

    Multi-actor involvement and cooperation are emphasized elements of destination development. Whereas prior research has addressed challenges involved in creating inclusive structures and trust through bottom-up approaches, this paper’s focus is on the less explored attitude of acceptance of a top-down structure. The case study of Ostrobothnia in Finland shows a regional destination organization that went from broad involvement to less inclusiveness and transparency. Through interviews with public and private stakeholders, it was found that the formal exclusion was accepted by all actors, even those who were excluded, based on their common high expectations of enhanced effectiveness of the new organization. Building on institutional theory and inclusiveness, it is suggested that the long-lasting formal collaboration had created the trust needed among the stakeholders for a new, lean management to replace the old. However, lasting formal collaboration may also lead to development of informal networks that hinder further interaction. Any formal collaboration or partnership between the public and private sectors therefore needs to acknowledge the local socio-political context to overcome established social hierarchies and open up for new influences. Co-determination should be held as a potential solution rather than an imposed structure, as it depends on expectations and local conditions.

    Abstract [en]

    Group supervision for teachers is a young, but strongly growing phenomenon in schools. Influencescome from many traditions, and supervision is given by different sorts of supervisors and fordifferent reasons, in different conditions and with different methods. The supervision discourse,which mainly comprises communicated experience, has increased significantly in the recent decades.However, there is little research in the area, and it can be said that almost nothing is known about thecharacter of the supervision, the contents and theoretical basis. Nor is supervision firmly establishedin the organisation, nor have the consequences for the school been studied.School leaders have a central role for the progress and development of supervision, they noticeneeds, make resources available, and buy in supervisory services. In this study, the principals’ discursiveunderstanding of the activity to which they hereby contribute, was investigated. The theoreticalthrust of the study can be assigned to a sociocultural perspective, as described mainly by Wertschand Säljö with contributions from Bakhtin. Linells context theory is a further starting point and forintepretation is used a hermeneutic method.12 school leaders with experience of, and positive attitude towards supervision of teacher teams,were interviewed about their experience and understanding of the activity. In preparation for theinterview stage a web-based survey was used and was answered by 433 people. The aim of the surveywas to create a basis for the interviews; choice of informants was as well as design of interviewquestions based on this.The analysis of the completed interviews was carried out by three readings of the material. Thefirst reading was at a descriptive level related to my understanding. The second reading investigatedthe informants’ understanding, by interpretation of how their discursive remarks were founded incultural and historical contexts. In the third reading, the interpretations were further widened anddeepened, by looking at the connections to the school and community.The results show that the school leaders’ contextual understanding creates different conditionsand supervision at their respective schools. Three main types of group supervision for practisingteachers were identified, activity-oriented, professional development and personnel support.Through the conceptualisation of supervision with different aims and directions, new and betterconditions and possibilities for different types of supervision are created. The results have subsequentlyindicated the need for different kinds of supervision of teacher teams in schools. In additionit was shown that school leaders also have a strong need for their own group supervision. In Swedenmany school leaders work alone in their respective schools, which means they have no opportunitiesto team work, and their professional role is weakened. Many emphasize that teachers and schoolleaders, in the same way as other professional groups, need continuous supervision talks, and formany school leaders this is the most important form of, not only competence development, by alsocompetence utilization.

    Supervised Teacher Development Groups - Super and Visionary to Whom and What?2006Conference paper (Other academic)
    Abstract [en]

    Supervised teacher groups have increasingly become a new way to meet demands for professional development in Swedish schools. The general purpose is to engage small groups of teachers in guided ongoing dialogues about their work, although the activity takes different forms. The purpose of the current study is to examine what principals’, supervisors’ and teachers’ perspectives on supervised teacher groups as means for learning and development are.

    A pre-study (web survey) among Swedish principals (Åberg 2004) shows a great deal of interest in guided professional dialogues, and an overwhelming conviction that they are a valuable means for school development. The results raise some important questions: Why are principals so enthusiastic? What kind of development is supported in these groups? What are the potential outcomes?

    The results of the follow-up interview survey with principals show that even though no systematic evaluations have been carried out at schools regarding what development group supervision supports, principals experience a number of positive changes within several areas: development of professional language, reflection and increased ability to clarify and deal with work tasks, improved problem-solving ability without expert assistance, improved cooperation and increased personal certainty in the professional role.

    There are examples of group supervision where the aim has primarily been adaptation to one another and to the objectives of the organization. However, there are, more importantly, many examples of development-focused group learning, groups that have become stronger, that have begun to question existing orders, groups that begin to look for their own answers and solutions to a greater extent, that have received insight and increased resources for independent actions and that, aided by supervision, have been able to break out of destructive patterns and poorly functioning cooperation.
