    Tracheid length – growth relationships of young Pinus brutia grown on reforestation sites2012In: IAWA Journal, ISSN 0928-1541, Vol. 33, no 1, p. 39-49Article in journal (Refereed)
    Abstract [en]

    Brutia pine (Pinus brutia Ten.) reforestations have been successfully used for decades in restoration of degraded forest ecosystems in Greece. The future purpose of these reforestations might expand to include wood utilisation. This study provides information on tracheid length of juvenile brutia pine aged 14–22 years grown on good and medium sites in Northeastern Greece. In addition, relationships among ring width, latewood proportion, wood density, and tracheid length were evaluated by using Causal Correlation Analysis. Similar mean tracheid length values were found for good and medium sites. Radial variability of tracheid length was similar on the good and medium sites, showing the typical increase in the juvenile phase. On both site types, latewood proportion showed a strong and positive relationship with wood density. Unexpectedly and only on the good sites, a significant positive relationship was found between ring width and wood density. On the medium sites, tracheid length was negatively related to fast growth and positively to high wood density. Tracheid length on the good sites was correlated only with latewood proportion with a weak positive relationship. The overall results may provide opportunities to better understand the quality of small-dimension timber of brutia pine and to better utilise it.

    The impact of Digital Technologies on Academic Libraries: a study in Greece2017Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Purpose: This study explores both library users’ and librarians’ experiences, benefits, and challenges depending on the implementation of digital technologies in academic libraries. The research has been taken place in two Greek academic libraries; In the Panteion University Library and in the Central Library of T.E.I. of Athens.Approach: Two research questions were developed for this research to be conducted and a sample size of 55 respondents (39 library users and 16 librarians) of the Panteion University Library and Central Library of T.E.I. of Athens, was evaluated.Findings: From the findings of the study, it was concluded that the general perception of both library users and librarians towards digital material and E-resources and services of the Panteion University Library and Central Library of T.E.I. of Athens, is satisfactory. Library users were satisfied with the convenience of digital material, the availability of E-resources provided by both academic libraries such as World Wide Web, WIFI, and online databases. They were not satisfied with library technology (i.e., computers) and library staff. Besides, results showed that services such as e-mail and Open Public Access Catalogue were used more often. Librarians were less satisfied with the digital library system, the limited personnel, and the financial funds for academic libraries in general.Implication: The results of this research have implications in the stakeholders of an academic library including the institutional management, the library administration, the librarians, the library users, the researchers, the community at large, and others.Value: This paper identifies critical issues related to the utilization of digital technologies and digital material; their benefits and challenges faced by librarians and library users as well as their effective operation from academic libraries in this information age.

    Patterns of neighborhood environment attributes related to physical activity across 11 countries: a latent class analysis2013In: International Journal of Behavioral Nutrition and Physical Activity, ISSN 1479-5868, E-ISSN 1479-5868, Vol. 10, article id 34Article in journal (Refereed)
    Abstract [en]

    Background: Neighborhood environment studies of physical activity (PA) have been mainly single-country focused. The International Prevalence Study (IPS) presented a rare opportunity to examine neighborhood features across countries. The purpose of this analysis was to: 1) detect international neighborhood typologies based on participants' response patterns to an environment survey and 2) to estimate associations between neighborhood environment patterns and PA. Methods: A Latent Class Analysis (LCA) was conducted on pooled IPS adults (N=11,541) aged 18 to 64 years old (mean=37.5 +/- 12.8 yrs; 55.6% women) from 11 countries including Belgium, Brazil, Canada, Colombia, Hong Kong, Japan, Lithuania, New Zealand, Norway, Sweden, and the U. S. This subset used the Physical Activity Neighborhood Environment Survey (PANES) that briefly assessed 7 attributes within 10-15 minutes walk of participants' residences, including residential density, access to shops/services, recreational facilities, public transit facilities, presence of sidewalks and bike paths, and personal safety. LCA derived meaningful subgroups from participants' response patterns to PANES items, and participants were assigned to neighborhood types. The validated short-form International Physical Activity Questionnaire (IPAQ) measured likelihood of meeting the 150 minutes/week PA guideline. To validate derived classes, meeting the guideline either by walking or total PA was regressed on neighborhood types using a weighted generalized linear regression model, adjusting for gender, age and country. Results: A 5-subgroup solution fitted the dataset and was interpretable. Neighborhood types were labeled, "Overall Activity Supportive (52% of sample)", "High Walkable and Unsafe with Few Recreation Facilities (16%)", "Safe with Active Transport Facilities (12%)", "Transit and Shops Dense with Few Amenities (15%)", and "Safe but Activity Unsupportive (5%)". Country representation differed by type (e. g., U. S. disproportionally represented "Safe but Activity Unsupportive"). Compared to the Safe but Activity Unsupportive, two types showed greater odds of meeting PA guideline for walking outcome (High Walkable and Unsafe with Few Recreation Facilities, OR=2.26 (95% CI 1.18-4.31); Overall Activity Supportive, OR=1.90 (95% CI 1.13-3.21). Significant but smaller odds ratios were also found for total PA. Conclusions: Meaningful neighborhood patterns generalized across countries and explained practical differences in PA. These observational results support WHO/UN recommendations for programs and policies targeted to improve features of the neighborhood environment for PA.

    Tourism in Mexico: More than Tacos and Tequila?: A Case Study on CSR Strategies of Swedish and Mexican Tour Operators in Mexico 2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to explore whether tour operators work with CSR within their organizations in Mexico, and describe how they implement it as well as why they work with it. Furthermore, the paper will analyze similarities and differences between the Swedish and Mexican tour operator’s CSR strategies as well as the reasons for this. Lastly, recommendations will be made to the Mexican tour operators on how they can gain knowledge from Swedish tour operators on CSR strategies and the development of these.The theoretical framework contains descriptions of theories on strategy, competitive advantage, the CSR Pyramid, stakeholder theory as well as CSR in the context of developing countries, which are all relevant theories for the issue studied as well as for answering the research questions. The empirical findings that have been collected through interviews with two Swedish, and two Mexican tour operators address the respective tour operator’s work with CSR in Mexico.In the analysis the theoretical framework has been put in relation to the empirical evidence. The analysis consists of how and why CSR activities are implemented in the respective organization. It also addresses the difficulties tour operators from developed countries face when implementing CSR on destinations in developing countries.Lastly, our conclusions show that there are several ways of implementing CSR in developing countries, as well as different views on why taking social responsibility within the tourism industry is important. Moreover, the main reason for this divergence lies in different perspectives, which has also been shown to be a contributing factor to the challenges faced by Swedish tour operators in the context of a developing country.In the end of the thesis recommendations will be made to Mexican firms on how to develop, and implement CSR strategies more successfully as well as recommendations for further research within the field of CSR in developing countries.

    How to survive as an expatriate in China2006Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The increase of foreign direct investment in China has resulted in the presence of a number of Western expatriates working in Sino–foreign joint ventures. These expatriate managers have to make things work in absolutely new settings. Therefore, without cross-cultural trainings, they may have very stressful experience in China. Understanding of the Chinese culture and Chinese society may ultimately save much frustration and money. With our thesis therefore we would like to explore how companies manage training processes before sending expatriates to China, and prepare them for further knowledge transfer to the employees in China. This has lead us to the following research question: “How do the Western companies manage process of sending expatriates to China?”

    The research is based on the experiences of three companies: IKEA, Texol Technical Solutions and NCR and demonstrates possible means that can be engaged by the companies to facilitate adjustment processes of their expatriates in China. The empirical data were gathered from interviews with managers from the mentioned companies. In order to analyze our empirical findings we present literature that was structured as follows: Training in the international context, training in the Chinese context and communication between expatriate and local employees. Both the literature review as well as our empirical data with analysis aspire to provide the reader with an in depth study of the importance of the selection of the right candidates and the provision of trainings, as it can help both to understand the unique Chinese cultural and business characteristics environment as well as effectively and efficiently to operate in China.

    In our conclusions we present our findings regarding the following issues: support for the expatriates; training of the Chinese employees and importance of communication. Based on our analysis we introduce our recommendations for the three companies, including: Selection of the right candidates, presence of action plans, motivation and incentives, trainings, contact with the company and other expatriates during the assignment and importance of repatriation.

    Title: The user's role in Environmental Performance Measurement- A case study on Växjö municipality

    Background: Increased awareness of the environment in society, growing public pressure and more regulations have affected public organisation's efforts in the environmental field. The result of this effort is that environmental performance measurements have been implemented from the private sector so that public organisations can demonstrate improvements and make evaluations of their work on environmental issues. However, researchers argue that collecting information about performance is not enough, the information also needs to be used in the organisation. Therefore it became interesting to study how public sector managers use information from Environmental performance measurements and why the information is used.

    Purpose: The purpose of this study is to describe and analyse how managers at Växjö municipality use information from Environmental Performance Measurements and explain why the information is used. In addition, the study aims at providing improvement proposals that support Växjö municipality's work on Environmental Performance Measurement.

    Methods: This study is a qualitative case study with Växjö municipality as the case. In collecting data, qualitative interviews have been conducted, but data is also collected through internal documents, such as Växjö municipality's Environmental Program

    Results and conclusions: The study's results shows that managers at Växjö municipality mainly use information from Environmental Performance Measurements for internal purposes, although some managers are more likely to use information than others. The study's results also shows that the work on environmental Performance Measurement can be further developed.

    Title: Reward system and motivation – A multi-case study in the construction industry

    Authors: Philip Adamsson, Gabriel Andersson, Johannes Petersson

    Examiner: Elin Funck

    Supervisor: Natalia Semenova

    Background and problem: A reward system is an instrument that is widely used, where management with help of a functional reward system can get a desired behavior from an employee. How a reward system is designed differs between sectors. The construction industry is a sector bordered by conflicts of interest between employers and employees. Is there a match between the employer's intention with reward systems and employee’s perception of the reward system? There are multiple rewards that can provide a desired behavior, but what is it that really motivate employees in the construction industry.

    Purpose: The purpose of this study is to describe how the reward system is designed in the construction industry. Furthermore, the purpose of the study is to see if the employer's intentions and the employee's perception of the reward system is consistent. The study also intends to describe why, or why not employees feel that the reward system motivates them.

    Methods: We conducted a multi-case study of Svensk Vattenbilningsteknik AB and TECAB Ytskyddsprodukter AB. Both companies are active in the construction industry. Empirical material were obtained through semi-structured interviews. The study had a deductive research approach.

    Conclusion: We can conclude that employers should focus on the purpose of their reward system to design a functional system. According to the study, a reward system should contain a combination of financial and non-financial rewards. Finally, a financial bonus should be a part of a construction company´s reward system, because it increases employee motivation and satisfaction.

    Creating a win-win-win-win situation: En fallstudie av den sociala entreprenörens motivation2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Socialt företagande utmärks av entreprenörens förmåga att identifiera samhällsproblem och tillmötesgå de sociala behoven i samhället. Det finns olika definitioner av socialt entreprenörskap, och dessa antyder att de styrande drivkrafterna skiljer sig ifrån de i traditionellt entreprenörskap. De motivationsfaktorer som den sociala entreprenören har skulle kunna återspeglas i hur verksamheten bedrivs och hur organisationens grundtankar förmedlas ut i företaget. Vidare skulle detta kunna ha en påverkan i strävan efter företagets uppsatta mål, vare sig deär socialt, miljömässigt eller ekonomiskt motiverade.

    Problemformulering: Vad finns det för drivkrafter hos en social entreprenör samt hur genomsyras det i företaget?Syfte:Syftet med uppsatsen är att genom fallstudie skapa ökad förståelse för den sociala entreprenören samt hur den motivation som finns visar sig iverksamheten.

    Metod: För uppsatsen har en kvalitativ ansats valts,och baseras på en fallstudie av ett företag vars verksamhet utgår ifrån socialt entreprenörskap. Data har samlats in via ett abduktivt tillvägagångssätt, genom semi-strukturerade intervjuer, observationer och teoretisk insamling.

    Slutsats: Uppsatsen påvisar de drivkrafter som finns hos den sociala entreprenören. Exempelvis att det primära målet är att uppnå en positiv social-och miljömässig påverkan i samhället, snarare än att generera en ekonomisk vinst. Andra drivkrafter är samtidigt att motivera och utbilda personalen inom medvetenhet om hållbarhet, säkerhet och kvalitet.

    Kommunikationskanaler vid intern nyhetsspridning: En fallstudie om hur kommunikationskanaler påverkar den upplevda kommunikationseffektiviteten vid nyhetsspridning2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Communication is an important function within organizations and the ways of communicating have developed rapidly due to technological development, which can make it difficult to know which communication channel that is best to use in different situations. This report is based on a case study were the perceived communication efficiency tended to vary depending on which communication channel that was used. Previous research shows how the choice of communication channels can affect the communication efficiency, however, it does not show this from the perspective of news as an information type. Therefore, it was considered interesting to study how different communication channels affect the communication efficiency in terms of news distribution.

     

    The aim of this study was to illustrate and describe how communication channels affect the perceived communication efficiency when the information that is transferred consists of news. To achieve this, the following research question would be answered:

     

    • What advantages and disadvantages do employees experience with communication channels regarding the communication efficiency for news distribution in a large national company?

     

    Theories that have been applied in the study are Media Richness Theory and Osgood and Schramms circular communication model. Theories have been used to explain how news distribution takes place in the case company and to illustrate and possibly explain the problems that the company experience with news distribution.

     

    Data was collected by applying a qualitative method in which semi-structured interviews have been used. The result shows that respondents experience both advantages and disadvantages with all the communication channels and that the perceived communication efficiency tended to vary depending on which kind of news. When the result was set against the research question and the theoretical framework, advantages and disadvantages that were experienced, turned out to be depending on if the news were routine or non-routine and how it was matched with a rich or poor communication channel, which Media Richness Theory also declare. 

     

    The conclusion of this study shows that news distribution through face to face and telephone enables direct interaction and transmission of emotions, however, emotions are not transmitted as well through telephone as face to face. The many signals can also be experienced as overwhelmingly. E-mail, intranet and signboard are effective in terms of time and are not as depending on time and space. In addition, the possibility of direct interaction and transmission of feelings is limited. The result indicates that advantages and disadvantages with the communication channels seems to be linked to whether the channel is perceived as suitable to transfer different kinds of news. Rich communication channels are perceived to be effective for transmitting non-routine news and poor channels are perceived to be effective for transmitting routine news.

    Exploring knowledge sharing in the Requirement Engineering phase of globally distributed Information Systems development: Perceived challenges and suggestions for improvement2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Master thesis explores the knowledge sharing that takes place during the requirement engineering phase of globally distributed information systems development. In recent years, due to globalization, information systems development activities have become increasingly distributed across different geographical locations. Requirement engineering is an important and knowledge intensive phase in the development of information systems. Requirement engineering is the process of identifying, analyzing, documenting, validating and managing the requirements of a system. Effective and efficient knowledge sharing during the requirement engineering is vital for the successful development of information systems. However, the global distribution of the stakeholders has affected knowledge sharing during requirement engineering in various ways making it more challenging.

     

    Drawing on the theories of knowledge sharing within the field of information systems, this interpretive research study aims at exploring stakeholders’ perceptions about the challenges met during the knowledge sharing in requirement engineering phase of globally distributed information systems development projects. More specifically, this Master thesis explores the perceived challenges and generates a list of suggestions to overcome the challenges by conducting qualitative semi-structured interviews among the key stakeholders, both customers and business analysts.

     

    The findings indicate that the knowledge sharing is influenced by challenges such as cultural differences, language barriers, communication issues, coordination issues arising from multiple stakeholders, time difference and difficulty in sharing tacit knowledge in the globally distributed settings. Participants’ suggestions for overcoming these challenges include cultural trainings, kick off meetings, language trainings, use of translator, face-to-face communication and interaction, video conferencing, scheduling important meetings in the common suitable timings, identification of the main stakeholders, having a mediator and making close observations with face-to-face interactions.

    Relationships between models used for teaching chemistry and those expressed by students2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is focused upon chemistry as a school subject and students' interpretations and use of formally introduced teaching models. To explore students' developing repertoire of chemical models, a longitudinal interview study was undertaken spanning the first year of upper secondary school chemistry. Matter in its different states was selected as the target framework for this study. The results presented are derived from both generalisations of groups of students as well as a case study describing an individual learner's interpretation of formal content. The results obtained demonstrated that the formal teaching models provided to the students included in this study were not sufficient to afford them a coherent framework of matter in its different states or for chemical bonding. Instead, students' expressed models of matter and phase change were to a high degree dependent on electron movement (Paper I), anthropomorphism (Paper II) and, for one student, a mechanistic approach based on small particles and gravitation (Paper III). The results from this study place focus on the importance of learners' prior learning (previous experiences) and the need to develop a coherent framework of formal teaching models for the nature of matter and phase change.

    Developing an Understanding of Chemistry: A case study of one Swedish student's rich conceptualisation for making sense of upper secondary school chemistry2014In: International Journal of Science Education, ISSN 0950-0693, E-ISSN 1464-5289, Vol. 36, no 7, p. 1107-1136Article in journal (Refereed)
    Abstract [en]

    In this paper, we report a case study of a 16-year-old Swedish upper secondary student's developing understanding of key concept areas studied in his upper secondary school chemistry course. This study illustrates how the thinking of an individual learner, Jesper, evolves over a school year in response to formal instruction in a particular educational context. Jesper presented a range of ideas, some of which matched intended teaching whilst others were quite inconsistent with canonical chemistry. Of particular interest, research data suggest that his initial alternative conceptions influenced his thinking about subsequent teaching of chemistry subject matter, illustrating how students' alternative conceptions interact with formal instruction. Our findings support the claims of some researchers that alternative conceptions may be stable and tenacious in the context of instruction. Jesper's rich conceptualisation of matter at submicroscopic scales drew upon intuitions about the world that led to teaching being misinterpreted to develop further alternative conceptions. Yet his intuitive thinking also offered clear potential links with canonical scientific concepts that could have been harnessed to channel his developing thinking. These findings support the argument that identifying students' intuitive thinking and how it develops in different instructional contexts can support the development of more effective science pedagogy.

    Learners' Mental Models of the Particle Nature of Matter: A study of 16-year-old Swedish science students2009In: International Journal of Science Education, ISSN 0950-0693, E-ISSN 1464-5289, Vol. 31, no 6, p. 757-786Article in journal (Refereed)
    Abstract [en]

    The results presented here derive from a longitudinal study of Swedish upper secondary science students' (16-19 years of age) developing understanding of key chemical concepts. The informants were 18 students from two different schools. The aim of the present study was to investigate the mental models of matter at the particulate level that learners develop. Data were collected using semi-structured interviews based around the students' own drawings of the atom, and of solids, liquids, and gases. The interview transcripts were analysed to identify patterns in the data that offer insight into aspects of student understanding. The findings are discussed in the specific curriculum context in Swedish schools. Results indicate that the teaching model of the atom (derived from Bohr's model) commonly presented by teachers and textbook authors in Sweden gives the students an image of a disproportionately large and immobile nucleus, emphasises a planetary model of the atom and gives rise to a chain of logic leading to immobility in the solid state and molecular breakdown during phase transitions. The findings indicate that changes in teaching approaches are required to better support learners in developing mental models that reflect the intended target knowledge.

    Designing play-based learning chemistry activities in the preschool environment2019In: Chemistry Education Research and Practice, ISSN 1756-1108, E-ISSN 1756-1108Article in journal (Refereed)
    Abstract [en]

    This study focuses on the design of play-based learning activities for chemistry in preschool. Viewing chemistry as a part of our past and present culture instead of as a subject, provides the backdrop for a more holistic approach to chemistry within this specific environment. A cultural-historical perspective, together with scaffolding, emergent science skills and sustained shared thinking, made up the framework for the design of the learning activities. Results show that when scaffolding and emergent science skills are used within the design, they provide good support for both the content and the teacher in the actual learning situation. Working with scaffolding was also beneficial for professional development. However, for a progressive and inclusive activity design, it is essential to take into account aspects of the immediate environment and methods for direct evaluation.

    Inverse analyses of effective diffusion parameters relevant for a two-phase moisture model of cementitious materials2018In: Cement and Concrete Research, ISSN 0008-8846, E-ISSN 1873-3948, Vol. 106, p. 117-129Article in journal (Refereed)
    Abstract [en]

    Here we present an inverse analyses approach to determining the two-phase moisture transport properties re-levant to concrete durability modeling. The purposed moisture transport model was based on a continuumapproach with two truly separate equations for the liquid and gas phase being connected by the sorption ki-netics. The moisture properties of ten binder-systems containingfly ash, calcined clay, burnt shale and graymicro-filler, were investigated experimentally. The experiments used were, (i) sorption test (moisturefixation),(ii) cup test in two different relative humidity intervals, (iii) drying test, and, (iv) capillary suction test. Masschange over time, as obtained from the drying test, the two different cup test intervals and the capillary suctiontest, was used to obtain the effective diffusion parameters using the proposed inverse analyses approach. Themoisture properties obtained with the proposed inverse analyses method provide a good description of the testperiod for the ten different binder-systems.

    Pore-scale modeling of vapor transport in partially saturated capillary tube with variable area using chemical potential2016In: Water resources research, ISSN 0043-1397, E-ISSN 1944-7973, Vol. 52, no 9, p. 7023-7035Article in journal (Refereed)
    Abstract [en]

    Here we illustrate the usefulness of using the chemical potential as the primary unknown by modeling isothermal vapor transport through a partially saturated cylindrically symmetric capillary tube of variable cross-sectional area using a single equation. There are no fitting parameters and the numerical solutions to the equation are compared with experimental results with excellent agreement. We demonstrate that isothermal vapor transport can be accurately modeled without modeling the details of the contact angle, microscale temperature fluctuations, or pressure fluctuations using a modification of the Fick-Jacobs equation. We thus conclude that for a single, axisymmetric pore, the enhancement factor depends upon relative humidity boundary conditions at the liquid bridge interfaces, distance between liquid bridges, and bridge lengths.

    Perceived impacts of Cloud Computing adoption on the role of an IT department of a higher institution in a developing country.2019Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    Cloud computing popularity has continued to be on the increase side, and it has been significant contributory factor to the of 24/7 365 days business culture of the digital 21st century where data and data centers are accessed via the internet through any connected device, anytime and from anywhere. Higher Education Institutions (HEI) or Tertiary Education Institution (TEI) are also among organisations, medium and large, that are tapping into this trend by gradually adopting this technology to reduce their high budgets in the prevailing face of financial shortage. This has particularly made the technology attractive to TEI in developing countries, and more of them are adopting the services being offered by cloud computing. The adoption of this technology however, affects the way and manner by which IT services are being delivered traditionally by the TEI IT or ICT departments. The objective of this study therefore, is to explore the adoption of this phenomenal technology and its impact on the role of traditional IT department in one of the tertiary education institution in the South Western part of Nigeria. The TOE framework adoption model was used to explore the adoption factors, and interviews conducted within the ICT department of the institution as part of the empirical findings process. In contrary to popular belief, no member of the IT staff has lost his or her job yet based on the adoption despite the impact on the skills and culture in service delivery of the department. IT staffs were encouraged to adapt to the change as quickly as possible with trainings given, and the ICT, thus the HEI have value added as most of the services are now available on a 24-hour basis to users, even while off campus and far remote, a dream very difficult and near impossible in the days of full traditional IT services delivery.

    Service Availability in Cloud Computing: Threats and Best Practices2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Cloud computing provides access to on-demand computing resources and storage space, whereby applications and data are hosted with data centers managed by third parties, on a pay-per-use price model. This allows organizations to focus on core business goals instead of managing in-house IT infrastructure.                    

    However, as more business critical applications and data are moved to the cloud, service availability is becoming a growing concern. A number of recent cloud service disruptions have questioned the reliability of cloud environments to host business critical applications and data. The impact of these disruptions varies, but, in most cases, there are financial losses and damaged reputation among consumers.        

    This thesis aims to investigate the threats to service availability in cloud computing and to provide some best practices to mitigate some of these threats. As a result, we identified eight categories of threats. They include, in no particular order: power outage, hardware failure, cyber-attack, configuration error, software bug, human error, administrative or legal dispute and network dependency. A number of systematic mitigation techniques to ensure constant availability of service by cloud providers were identified. In addition, practices that can be applied by cloud customers and users of cloud services, to improve service availability were presented.

    Kan manuell analys av Csv-EPK ersättas med automatiserad analys på Sysmex XN-1000?2016Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    Determination of erythrocyte count in cerebrospinal fluid (CSF-EPC) is used to exclude various intracranial hemorrhage, especially subarachnoid hemorrhage (SAH). SAH means a bleeding between the pia mater and arachnoidea which occurs due to rupture of an aneurysm in the subarachnoid space. Manual counting of erythrocytes in the cerebrospinal fluid with Bürkers chamber and microscopy has been the gold standard for the past decades, but the manual method is time consuming and requires great experience. The purpose of this study was to evaluate if manual analysis of  CSF-EPC with counting chamber, and light microscopy can be replaced by automated analysis of CSF-EPC with Hematology Analyzer XN-1000 (Sysmex). Fortyeight cerebrospinal fluid samples with various concentrations of erythrocytes ware prepared by diluting known concentration of erythrocytes in cell-free CSF. Prepared CSF-samples with added erythrocytes were analyzed first on the XN-1000. Thereafter, manual counting of erythrocytes was performed using Bürkers counting chamber. A linear regression was established to describe the correlation between the automated analysis of the CSF-EPC and manual analysis of the CSF-EPC. Imprecision in the analysis of the CSF-EPC on the XN-1000 (Sysmex) was assessed by within-run imprecision. A very good correlation (r = 0.999) was found between the XN-1000 and manual counting. For results in the lower range, 100 - 5000 (106/L), correlation was also good (r = 0.997). The coefficient of variation was 19,8 % at CSF-EPC of 370 x 106/L and 3.1 % at CSF-EPC of 25 950 x 106/L. The sensitivity for analysis of CSF-EPC on XN-1000 was 370 x 106/L. The conclusion is that the analysis of Csv-EPC on XN-1000 can be used for clinical diagnostics of CSF- samples. However, it should be noted that XN-1000 has poor sensitivity for low CSF-EPC values < 370 x 106/L. To ensure high diagnostic quality even in CSF-samples with low erythrocyte counts are recommended a reference limit of < 500 x 106/L as a practical cut off for supplemental microscopic counting in routine healthcare laboratories.

    Isolering och identifiering av bakterie som orsakar missfärgning på kött2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Meat is skeletal muscle from different animals, such as pigs, cattle or sheep. Pseudomonas are bacteria that may cause food spoilage. The bacteria live in our environment and can cause problems due to biofilm formation in hospitals and industries. The slaughterhouse KLS Ugglarps has found that some pig cuttings have become discolored with at blue color and they wanted to find out what caused it. Pseudomonas aeruginosa had previously been found in the production area and was suspected as the cause.Meat, with and without discoloration, was investigated using various microbiological methods to see which bacterium cause the blue color. Different colonies were isolated and identified. The methods used were API 20NE, gram staining and oxidation test. A reference isolate was used as control. It was found that it was not P. aeruginosa but instead Pseudomonas fluorescens that caused the blue color. This was confirmed by applying the isolated bacteria to sterile meat and the blue color did appear after incubation. A screening for the source of contamination was performed in the production area to see if the bacterium could be found before start-up and during production. The samples taken showed that there were bacteria at both time points and that the production surfaces at the beginning of the production line were more prone to contamination than the other surfaces.

    Barnets bästa i umgänges– och vårdnadstvister: En diskursanalys av svenska domstolars resonemang2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to analyse how Swedish courts reason about the child's best in custody and access disputes. We have assumed different themes to analyse our empirical data, these themes were the child's best interests, perspective on the child's best interests, child's perspective, children as subjects or objects and finally the right of the child or the child's best interests. Our empirical data have consisted of 15 City Court and Court of Appeal judgments of the Swedish courts handed down in 2015. The study had a qualitative disposition and the selection was made strategically to make sure the empirical data would be relevant to our issues. We have used a discourse analysis where the intention was to study how the court reason about the child’s interests and what statements that gets preference and what gets excluded in the assessment. Our theoretical starting point was extracted from Foucault’s theory about power and his discourse concept. We have used the concept of his theory in our analysis, but also extracted the theoretical concepts from previous research. The result shows that the Court's assessment of what is in the child’s best interest is based primarily on a professional and adult perspective on the child's situation. The individual child's perspective was excluded and the Court was principally talking about children's needs and interests in general. The result also showed that children were seen as objects and not as participants in the majority of the cases.

    Tvåspråkiga elever: En undersökning om elevers inställning till sin tvåspråkighet.2011Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med den här studien är att ta reda på hur elever med svenska som andra språk, beskriver sina erfarenheter av att vara tvåspråkiga. Syftet med studien är också att ta reda på vad fördelarna respektive nackdelarna är att vara tvåspråkig i skolan.

    Metod: Undersökningsmetoden för studien är en kvalitativ metod med intervjuer av fem informanter.

    Resultat: Studien visar att elevers förhållningssätt gentemot sin tvåspråkighet är positiv. Eleverna anser att kunna två språk är en fördel samt att det leder färdigheter av förståelse av andra kulturer och kunskap i andra ämnen. Att bevara modersmålet anses också något som en viktig del av elevernas inställning till sina två språk vare sig det gäller att man förstärker den genom sin omgivning eller i undervisning. Omgivningen lägger också mycket intryck på deras tvåspråkighet, där positiva fördelarna också framhävs mer genom att eleverna aktivt använder språket med familjen, vänner och i skolan.

    Mobbning i skolan: Elevers hälsa och de olika mobbningsstrategierna2011Independent thesis Basic level (professional degree), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: I dagens skola finns det elever som tyvärr blir trakasserade av andra elever. Mobbning är ett problem som existerar i dagens skola som behöver lyftas fram samt där alla inom skolverksamheten blir medvetna om vad mobbning kan orsaka för negativa effekter.

    Syfte: Vi vill med denna litteraturstudie undersöka hur mobbning kan påverka barn och ungdomars hälsa samt undersöka hur olika metoder och strategier av mobbning används för att mobba.

    Metod: Det här är en systematisk litteraturstudie där vi sökte inom databaserna: ELIN, ERIC och Libris. Vi har använt oss av sju olika vetenskapliga artiklar i vår studie.

    Resultat: Vi har med vår litteraturstudie kommit fram att ungdomars psykiska hälsa påverkas starkt av mobbning oberoende om man är offer till mobbning eller en mobbare som utför trakasserier. I vår undersökning har vi även funnit att metoden för att utföra mobbning via nätet samt användningen av elektronik är en strategi för att trakassera individer.

    Slutsats: Dagens skola behöver vara uppmärksam att mobbning kan förekomma ur olika strategier. Nätmobbning ingår i den verbala mobbningen. Det är ett nytt och modern sätt för ungdomarna att använda sig av för att hota och trakassera en individ. Men också en av de lättaste att upptäcka än exempelvis tyst mobbning samt är en av de enklaste att upptäcka. Det är också viktigt att påpeka att individer oavsett de som blir utsatta av mobbning och de som utför handlingarna inte mår bra av mobbning.

    Libyenkrisen – en humanitär intervention?: En kvalitativ textanalys som syftar till att förklara motiven bakom NATO:s och FN:s beslut att intervenera Libyen2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Humanitarian intervention is a concept that generates several problems in our time. The idea of humanitarian intervention concerns the modern norms of sovereignty and noninterventional principals. It also concerns the conventional norm, which declares that states are not allowed to interfere in other states’ internal affairs. The use of military force to implement humanitarian intervention is restricted according to international law. This is what this thesis intends to investigate. The purpose was to find out the causes behind the intervention in Libya, which was carried out by NATO. The main questions were (1) to find out if the intervention in Libya was a humanitarian intervention (2) or if there were other motives that were behind the intervention. Two classical international relations theories have been utilized for the analysis. The analysis focused on the five UN Security Council members’ statements and arguments, which have been expressed in the UN Security Council. This issue created a gap between the members of the Security Council, especially between the Western states and the Russian and Chinese authorities

    Probabilistic Analysis of the EPR-Bohm Experiment2007Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Bell's Theorem was developed on the basis of considerations

    involving a linear combination of spin correlation functions, each

    of which has a distinct pair of arguments. The simultaneous

    presence of these different pairs of arguments in the same

    equation is investigated, and the implicit counterfactual

    assumption in Bell's theorem is discussed.

    We show how an explicit contextuality can arise from a model

    displaying unfair sampling, and we discuss it in the

    framework of David Mermin's cleverly simple version of Bell's

    theore, which pinpoints in a very straightforward way how

    interpreting entanglement from a realistic point of view can be

    problematic. We present an extended version of Mermin's device

    that can actually be given a straightforward realistic

    interpretation.

    We stress that the low efficiency of detectors in all experiments

    with photons makes the use of the fair sampling assumption

    unavoidable. Since this very assumption is false in all existing

    local realistic models based on inefficient detection, we thus

    question its validity. We show that it is no more reasonable to

    assume fair sampling than it is impossible to test, and we

    actually propose an experimental test which would provides clear

    cut results in case of unfair sampling

    We then analyze optical EPR experimental data performed by Weihs et al in Innsbruck 1997-1998. We show that for some linear

    combinations of the raw coincidence rates, the experimental

    results display some anomalous behavior that a more general source state (like non-maximally entangled state) cannot

    straightforwardly account for. We use the fair sampling

    assumption, and assume explicitly that the detection efficiencies

    for the pairs of entangled photons can be written as a product of

    the two corresponding detection efficiencies for the single

    photons. We show that this explicit use of fair sampling cannot be

    maintained to be a reasonable assumption as it leads to an

    apparent violation of the no-signalling principle.

    Abstract [en]

    We present some recent results of a new statistical analysis of the optical EPR experiment performed by Weihs et al in Innsbruck 1997-1998. Under the commonly used assumption of fair sampling, we show that the coincidence counts exhibit a small and anomalous non-signalling component, which seems impossible to explain by using the conventional quantum mechanics, and we discuss some possible interpretations of this phenomenon.

    Is the fair sampling assumption supported by EPR experiments?2007In: Journal of Physics B: At. Mol. Opt. Phys., ISSN 0953-4075, Vol. 40, no 1, p. 131-141Article in journal (Refereed)
    Abstract [en]

    We analyse optical EPR experimental data performed by Weihs et al in Innsbruck 1997–1998. We show that for some linear combinations of the raw coincidence rates, the experimental results display some anomalous behaviour that a more general source state (like non-maximally entangled state) cannot straightforwardly account for. We attempt to explain these anomalies by taking account of the relative efficiencies of the four channels. For this purpose, we use the fair sampling assumption, and assume explicitly that the detection efficiencies for the pairs of entangled photons can be written as a product of the two corresponding detection efficiencies for the single photons. We show that this explicit use of fair sampling cannot be maintained to be a reasonable assumption as it leads to an apparent violation of the no-signalling principle.

    Test of the no-signaling principle in the Hensen loophole-free CHSH experiment2017In: Fortschritte der Physik, ISSN 0015-8208, E-ISSN 1521-3978, Vol. 65, no 9, article id 1600096Article in journal (Refereed)
    Abstract [en]

    We analyze the data from the loophole-free CHSH experiment performed by Hensen et al., and show that it is actually not exempt of an important loophole. By increasing the size of the sample of event-ready detections, one can exhibit in the experimental data a violation of the no-signaling principle with a statistical significance at least similar to that of the reported violation of the CHSH inequality, if not stronger. The data from the loophole-free CHSH experiment performed by Hensen et al. are analysed, It is shown that it is actually not exempt of an important loophole. By increasing the size of the sample of event-ready detections, one can exhibit in the experimental data a violation of the no-signaling principle with a statistical significance at least similar to that of the reported violation of the CHSH inequality, if not stronger.

    Double Blinding-Attack on Entanglement-Based Quantum Key Distribution Protocols2012In: AIP Conference Proceedings, ISSN 0094-243X, E-ISSN 1551-7616, Vol. 1424, no 1, p. 9-16Article in journal (Refereed)
    Abstract [en]

    We propose a double blinding-attack on entangled-based quantum key distribution protocols. The principle of the attack is the same as in existing blinding attack except that instead of blinding the detectors on one side only, Eve is blinding the detectors of both Alice and Bob. In the BBM92 protocol, the attack allows Eve to get a full knowledge of the key and remain undetected even if Alice and Bob are using 100% efficient detectors. The attack can be easily extended to Ekert protocol, with an efficiency as high as 85.3%.

    Multiple-photon absorption attack on entanglement-based quantum key distribution protocols2013In: Quantum Bio-Informatics V: Proceedings of the Quantum Bio-Informatics 2011 : Tokyo University of Science, Japan, 7 – 12 March 2011 / [ed] Luigi Accardi, Wolfgang Freudenberg, Masanori Ohya, Singapore: World Scientific, 2013, vol. 30, p. 171-180Conference paper (Refereed)
    Abstract [en]

    We propose a multiple-photon absorption attack on Quantum Key Distribution protocols. In this attack, the eavesdropper (Eve) is in control of the source and sends pulses correlated in polarization (but not entangled) containing several photons at frequencies for which only multiple-photon absorptions are possible in Alice's and Bob's detectors. Whenever the number of photons from one pulse are dispatched in insufficient number to trigger a multiple-photon absorption in either channel, the pulse remains undetected. We show that this simple feature is enough to reproduce the type of statistics on the detected pulses that are considered as indicating a secure quantum key distribution in entangled-based protocols, even though the source is controlled by Eve, and we discuss possible countermeasures.

    Alla säger I Love You: Om orden som gör känslor och känsliga formuleringar.2007In: Bang : feministisk kulturtidskrift, ISSN 1102-4593, Vol. 3, p. 91-93Article in journal (Other (popular science, discussion, etc.))
    Abstract [sv]

    Artikeln handlar om hur orden "jag älskar dig" respektive "I love you" får betydelse både personligt, socialt och politiskt. Exempel hämtas från tv-serierna "Förhäxad" och "Sex and the City" och författaren resonerar kring hur orden skapar affektiva betydelser i kropp och genuspositioner.

    Abstract [sv]

    Äktenskapet står starkt som juridiskt skydd i Sverige, samtidigt som man fokuserar på jämställdhet och allas lika värde. Kungahuset ordnar bröllop med jämlik aura. Har kritiken av äktenskapet glömts bort?

    Inte den typ som gifter sig?: Feministiska samtal om äktenskapsmotstånd2008Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Den här avhandlingen undersöker frågan om äktenskapsmotstånd i dagens svenska samhälle, media och kultur. Boken belyser olika sätt att uttrycka äktenskapsmotstånd och vad det betyder att formulera feministisk kritik av normerande familjevärderingar.

    Undersökningen baseras på etnografi och kritisk kulturanalys och granskar synen på äktenskap, relationer och familj som ett kulturellt imaginärt fält. Det empiriska materialet består av intervjuer med kvinnor som inte har velat gifta sig, liksom ett brett material från tv, webbsidor, dagstidningar, skvallerpress och bloggar.

    I avhandlingen genomförs och presenteras en feministisk metodologisk process, grundat i akademiskt kreativt och självreflexivt skrivande. Detta innebär att skrivprocessen, textformatet, liksom minnesarbete, olika intervjutekniker och andra kreativa analytiska praktiker är en del av det metodologiska ramverket.

    De teoretiska perspektiven som ligger till grund för denna studie består av flera feministiska strömningar: radikalfeminism, queerfeminism, liberealfeminism, anarkafeminism och ett socialt rättviseperspektiv. De belyser, på olika sätt, intersektioner mellan äktenskap, genus, sexualitet, nationalitet, klass och makt. En gemensam utgångspunkt är att identitetskategorier, möjligheter att agera liksom vår plats i världen är konstruerade av maktrelationer och normativa föreställningar om genus. Dessa perspektiv tillhandahåller analytiska verktyg för att diskutera och dekonstruera kulturella föreställningar om äktenskap och äktenskapsmotstånd.
