    Specifying frameworks and design patterns as architectural fragments1998Conference paper (Refereed)
    Abstract [en]

    Object-oriented software architectures, such as design patterns and frameworks, have Sound extensive use in software industry. Their implementation in traditional object-oriented programming languages, however, is often difficult, since no support for the explicit specification of software architectures is provided. In. this paper, we develop the notion of architectural fragments, i.e. reusable architectural specifications that describe a design pattern, or a framework architecture. An architectural fragment describes the structure of an architecture in terms of its components (roles), the architect architecture-specific behaviour of the components and the architecture-specific interaction between the components. Fragments can be composed with each other and with reusable components. To illustrate the use of fragments, we describe the role and architecture language constructs in the layered object model ((LOM)-O-AY) and present examples.

    Specifying Frameworks and Design Patterns as Architectural Fragments1997Report (Refereed)
    Abstract [en]

    Object-oriented software architectures, such as design patterns and frameworks, have found extensive use in software industry. As a design technique, these architectural structures have proven themselves very valuable. Their implementation in traditional object-oriented programming languages, however, is often difficult, since these languages provide no support for the explicit specification of software architectures. In this paper, we develop the notion of architectural fragments, i.e. reusable architectural specifications that describe a design pattern or a framework architecture. An architectural fragment describes the structure of an architecture in terms of its components (roles), the architecture-specific behaviour of the components and the architecture-specific interaction between the components. Fragments can be composed with each other and with reusable components. To illustrate the use of fragments, we describe the role and architecture language constructs in the layered object model (LayOM) and present examples.

    Third Student Conference on Advanced Object-Oriented Concepts1999Report (Other academic)
    Abstract [en]

    The articles in this research report are the result of the efforts of the students of the master course on advanced object-oriented concepts. The course is part of the software engineering master year at the University of Karlskrona/Ronneby. During the course, the students were introduced to about 20 advanced object-oriented concepts, such as delegation, prototype-based languages, reflection, typing, real-time and concurrent object-oriented languages, dynamic binding, garbage collection, delegating compiler objects, design patterns and frameworks. Rather than passively being present at the classes and listening to the lectures, the students were required to themselves present these new concepts. This required considerable amounts of active searching and independent knowledge acquisition from the students that had, subsequently, to be converted in a one to two hour lecture. The lecture was followed by a discussion involving all students. The organisation of the course lead to a very effective learning of the various concepts that were part of the course. Another, very important, aspect of the course was that each student was required to write a research paper on a subject within the object-oriented domain. One requirement on the article was that it had to be problem-oriented in that it had to identify a problem and subsequently propose a solution to the problem. Rather than writing a literature survey, the student was required to write a paper that contained a (possibly minor) scientific contribution to the object-oriented domain. During the course, writers workshops were organised during which students, in groups, read and commented on papers written by their colleagues. The results of this part of the course are gathered in this research report. Fourteen student research papers form the contents of this research report. The articles have been classified into four categories, i.e. reuse and evolution, object-oriented languages, software design and object-oriented frameworks. The reader will recognise, perhaps surprisingly, that many of the papers are strongly founded in practical experiences and address relevant technical problems that our software industry has to deal with on day to day basis. The explanation for this can be found in the project-oriented organisation of the software engineering study program and the strong relation to the local software industry. During the first three years of their studies, the students have experienced the real problems in software engineering and during the master year the students learn to reflect on these problems and to develop solutions. At the end of the course for this year, I am happy that I can conclude that the goals of the course have been more than achieved. Many of the lectures were of very good quality, the participation in the discussions was more than satisfactory and the research papers are very worthwhile reading. The course required from the students, but also from the teacher, a considerable effort, that, almost certainly, resulted in a highly valuable learning experience. For my part, I look with great satisfaction back on the course and hope for many successful repetitions in the future.

    Tool Support for Language Extensibility1996Report (Refereed)
    Abstract [en]

    During the last years, one can recognise a development towards application domain languages and extensible language models. Due to their extended expressiveness, these language models have considerable advantages over rigid general purpose languages. However, a complicating factor in the use of extensible language models are the conventional compiler construction techniques. Compilers constructed using these techniques often are large entities that are highly complex, difficult to maintain and hard to reuse. As we have experienced, these characteristics clearly complicate extending existing compilers. As a solution to this, we developed an alternative approach to compiler construction is proposed, based on object-oriented principles. The approach is based on delegating compiler objects (dcos) that provide a structural decomposition of compilers in addition to the conventional functional decomposition. The dco approach supports modularisation and reuse of compiler specifications, such as lexer and parser speci fications. We constructed an integrated tool set, letos, implementing the functionality of delegating compiler objects.

    OOSA’98: ECOOP'98 Workshop on Object-Oriented Software Architectures1998Report (Other academic)
    Abstract [en]

    Recently, one can recognize an increased awareness in the object-oriented research community with respect to the role of software architectures. Examples of this can, among others, be found in object-oriented frameworks and design patterns. In the call for papers for the workshop, the following topics were identified where software architecture, patterns and frameworks should be studied in more detail: · Building OO software architectures: How can design patterns, frameworks and components be included in the traditional object-oriented analysis and design? How are architecture constraints processed to build OO software architectures? Which techniques can help to build an OO architecture that supports reuse and is scalable? · Language role in architecture: What is the role of a particular object-oriented language when designing an architecture? · Architecture documentation: It has been suggested that design patterns can be used to document the design and rationale of an object-oriented architecture. How well does this work in practice? · OO architectural styles: What is the relation between the architectural styles of Garlan and Shaw and OO design? · Composition of architectures: Since object-oriented frameworks are an accepted technology within the software industry, the composition of two or more frameworks in an application occurs increasingly often. The composition may be far from trivial and the problems that may appear as well as solutions should be investigated. · Component technologies and architectures: Components are becoming key elements of reusable software development, and various technologies have emerged to support the specification of components and their use in unpredictable combinations (e.g. Java Beans). What are the relations between component-oriented and framework-oriented architectures? How do different component communication mechanisms affect the architecture? · Architecture evaluation: Even though object-oriented frameworks claim to promote reuse and decrease development cost, there are no techniques available to evaluate a concrete framework to determine whether it supports the functional and, especially, non-functional requirements for an application intended to be built based on the framework. 'Domain creep': Several examples of frameworks exist that, over time, are applied in domains differing from the originally intended domain. The framework then needs to be adapted to include the new domain as well, either as an integrated framework or as two versions. The problems associated with domain creep need to be identified and solution strategies identified. · Experiences: Object-oriented software architectures are used out in industry and academia. However, often no explicit evaluation is performed and experiences are not captured and described objectively. The experiences, case studies and concrete systems and identify problems and weaknesses, but also successful structures and approaches need to be described. · Tool support: A considerable need for architecture tool support exists. Examples are visualization, editing, design, and documentation of architectures. The goal of the OOSA'98 workshop was to study the aforementioned topics, define the research area and state-of-the-art in more detail and to identify open problems. The call resulted in 15 papers accepted for the workshop. These papers were divided over 5 sessions. Each session was divided in a presentation part, in which the authors briefly presented their work, and a discussion part where the audience was able to discuss the presented and related ideas with the authors and each other. In the remainder of this workshop summary, the results from each session are presented.

    Abstract [en]

    Software architecture research is receiving increased amounts of attention in academia as well as in industry. Therefore, in 1997 the initiative was taken by the University of Karlskrona/Ronneby to start a network of academic and industrial partners, SARIS, interested in various aspects of software architecture. The intention of the SARIS (Software Architecture Research in Sweden) network is to bring together partners with common interests, exchange experiences through the mailing list and regular meetings and to develop cooperation wherever possible. The term software architecture is somewhat overloaded, but most experts agree that it primarily refers to the top-level decomposition of a system into its main components and the interaction between these components. A second aspect is that software architecture design is primarily concerned with the non-functional requirements (also properties or quality attributes) of software systems, rather than their functionality. Attributes can be categorized into operational attributes, such as efficiency, reliability, robustness and cor-rectness, and development attributes, such as maintainability, flexibility and reusability. The architecture structures the functionality required from a system such that the non-functional requirements are fulfilled.

    Multiple Object Interfaces in Object-Oriented Control Systems1996Conference paper (Refereed)
    Abstract [en]

    When modelling complex computer systems, four primary modelling techniques are available to the software engineer, i.e. abstraction, composition, functional decomposition and multiple client interfaces (views). Abstraction and composition can directly be expressed in traditional object-oriented models and functional decomposition can often be expressed using subsystems. However, traditional object models provide no expressiveness for multiple client interfaces. This forces designers to either model all different views on a conceptual object as a large, complex implementation object or to model each view as an object and relate the different view objects. Both approaches suffer from problems of complexity, maintainability and reusability. As a solution, we propose the layered object model that allows for the expressive, flexible and extensible definition of multiple client interfaces. To illustrate the problems associated with views and our proposed solution, the domain of industrial control systems is used.

    A Model for a Flexible and Predictable Object-Oriented Real-Time System1997Conference paper (Refereed)
    Abstract [en]

    The requirements on real-time systems are changing. Traditionally, reliability and predictability of hard, real-time systems in particular were the main requirements. This lead to systems that were stand-alone, embedded and static. Future real-time systems, but even current systems, still require reliability and predictability, but also distribution of the real-time system, integration with non real-time systems and the ability to change dynamically the components of the system at run-time. Traditional approaches to real-time system development have difficulty in addressing these additional requirements. New ways of constructing real-time systems must therefore be explored. In this article, we develop a real-time object-oriented model that facilitates the requirements of flexibility without sacrificing the predictability, integration and dynamicity aspects.

    Software architecture design: Evaluation and transformation1999Conference paper (Refereed)
    Abstract [en]

    Since the architecture of a software system constrains the quality attributes, the decisions taken during architectural design have a large impact on the resulting system. An architectural design method is presented that employs iterative evaluation and transformation of the software architecture in order to satisfy the quality requirements. Architecture evaluation is performed by using scenarios, simulation, mathematical modelling and experience-based reasoning. The architecture can be transformed by imposing an architectural sg le, imposing an architectural pattern, using a design pattern, converting a quality requirement to functionality and by distributing quality requirements. The method has evolved through its application in several industrial projects.

    Since the architecture of a software system constrains the non-functional requirements, the decisions taken during architectural design have a large impact in the resulting system. An architectural design method is presented that employs iterative evaluation and transformation of the software architecture in order to satisfy the non-functional requirements (NFRs). Architecture evaluation is performed by using scenarios, simulation, mathematical modelling and reasoning. The architecture can be transformed by imposing an architectural style, imposing an architectural pattern, using a design pattern, converting an NFR to functionality and by distributing NFRs. The method has, in various forms, been applied in several industrial projects.

    Proceedings of the Fifth International Workshop on Component-Oriented Programming (WCOP 2000)2000Report (Other academic)
    Abstract [en]

    WCOP 2000, held in conjunction with ECOOP 2000 in Sophia Antipolis, France, was the fifth workshop in the successful series of workshops on component-oriented programming. The previous workshops were held in conjunction with the respective ECOOP conferences in Linz, Austria, Jyväskylä, Finland, Brussels, Belgium and Lisbon, Portugal. WCOP96 had focused on the principal idea of software components and worked towards definitions of terms. In particular, a high-level definition of what a software component is was formulated. WCOP97 concentrated on compositional aspects, architecture and gluing, substitutability, interface evolution, and non-functional requirements. WCOP98 had a closer look at issues arising in industrial practice and developed a major focus on the issues of adaptation. WCOP'99 moved on to address issues of component frameworks, structured architecture, and some bigger systems built using components frameworks. The topics for WCOP 2000 focused on component composition, validation and refinement and the use of component technology in the software industry.

    WCOP ´99: Proceedings of the Fourth International Workshop on Component-Oriented Programming1999Report (Other academic)
    Abstract [en]

    WCOP'99 is the fourth event in a series of highly successful workshops, which took place in conjunction with every ECOOP since 1996, focusing on the important field of component-oriented programming (COP). COP has been described as the natural extension of object-oriented programming to the realm of independently extensible systems. Several important approaches have emerged over the recent years, including CORBA, COM (COM+, DCOM, ActiveX, DirectX, ...), JavaBeans. A component is not an object, but provides the resources to instantiate objects. Often, a single component will provide interfaces to several closely related classes. Hence, COP is about architecure and packaging, besides interoperation between objects. After WCOP'96 focused on the fundamental terminology of COP, the subsequent workshops expanded into the many re- lated facets of component software. WCOP'99 shall emphasis architectural design and construction of component-based systems beyond ad-hoc reuse of unrelated components. To enable lively and productive discussions, the workshop will be limited to 25 participants. Depending on the actually submitted positions papers, the workshop will be organized into three or four subsequent mini-sessions, each initiated by a presentation of two or three selected positions and followed by discussions. Instead of splitting the workshop into task forces, it is intended to provoke lively discussion by preparing lists of critical questions and some, perhaps provocative, statements (to be used on demand). Position papers will be formally reviewed, each by at least two independent reviewers. As an incentive for submission of high quality statements, the best position statements will be combined with transcripts of workshop results and published.

    Crossing Learning Boundaries. The Utility related Virtual Organisation ISES1997In: VoNet http://www.virtual-organization.net/, Vol. 5 Article in journal (Refereed)
    Abstract [en]

    Due to changing circumstances, organisations start to co-operate with their competitors or with firms form other industries that can complement their range of products. This development of independent partners sharing, their resources and equipment with each other, can also be seen in the Swedish utility industry and will soon happen to other utility businesses after the deregulation of the European utility industry has become a fact. The co-operation can be seen as a virtual organisation and this research project investigates how virtual organisations operate and how partners establish and maintain such an organisation. For this reason the R&D virtual organisation ISES, formed by the utility related joint venture EnerSearch AB, is taken as a case study. When comparing a virtual organisation with traditional organistions, five boundaries are presented that can both create and inhibit learning and communication. Since learning can be viewed as a major objective of a virtual organisation, the five boundaries ar e discussed in more detail and are related to empirical results in the project ISES. These boundaries in time, space, diversity, structure, and distribution are characteristics of a virtual organistion. By observing this organisation, opportunities and obstacles of a virtual organisation are found that could help organisations who would like to establish a virtual organsition. One example is the difference in decision styles or personality of the members of a virtual organistion, which influences information distribution, communication and co-operation.

    Stimulating cooperation in Interorganisational Relationships1996Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The purpose of this thesis is two-fold. First the researcher wants to investigate the gradation of information needs, in order to made a classification of important information and communication aspects of the focal organisation EnerSearch. Secondly, in order to state a classification of information, a vocabulary is developed that could help actors to understand the situation under investigation. Method The methodology used is partly an action research methodology, where the researcher plays an active role in interpreting and understanding the situation together with the actors of the focal organisation. The research exerts from a hermeneutic perspective, where activities in the focal organisation are interpreted and concepts are developed that can help actors of the investigation, to understand their situation. For the investigation a case study is taken and the researcher has an active role in the case study. Conclusion The found data is summarised by using ideal types that characterise persons in the focal organisation. The ideal types used are: clients (members of the management and financiers), involved and individualists (both operating core). These three groups have different needs of information, communication and objectives. With help of these groups a classification of information distributed in the organisation is made, based on a division between: information based on destination (to whom the message is sent) and content (what is the content of the information sent). This division is used in order to find the most suitable media that could be used for transmitting this information and this is done with help of the information richness theory of Daft & Lengel (1990). By distributing information and by communicating with each other, one could also state that co-ordination is party stimulated with these results. Furthermore, the results found can be implemented in an information system that is adjusted to the requirem ents of the participants of the focal organisation. For this reason a primitive design of an information system is proposed that could support the aforementioned classification and that could support communication and information distribution in the focal organisation.

    Virtualising the Utility Industry through Interorganisational Learning1997Conference paper (Refereed)
    Abstract [en]

    Due to changing circumstances, organisations start to co-operate with their competitors or with firms from other industries that can complement their range of products. This development of independent partners sharing their resources and equipment with each other can also be seen in the Swedish utility industry and will soon happen to other utility businesses after the European utility deregulation has become a fact. This co-operation can be seen as a virtual organisation and research is performed on how virtual organisations operate and how partners establish and maintain such an organisation. For this reason the R&D virtual organisation called ISES formed around the utility related joint venture EnerSearch AB. When comparing a virtual organisation with traditional organisations, five boundaries are presented that can both create and inhibit learning and communication. Since learning can be viewed as a major objective of a virtual organisation, the five boundaries are discussed in more detail and are related to empirical results in the project ISES. These boundaries are time, space, diversity, structure and distribution and are characteristics of a virtual organisation. By observing this organisation, opportunities and obstacles of a virtual organisation are presented that could help organisations who initiate to establish a virtual organisation. One example is the difference in decision styles or personality of the members of a virtual organisation, which influences information distribution, communication and co-operation.

    Virtual versus Physical: The Future?1996Conference paper (Refereed)
    Abstract [en]

    In organisational science, new organisational concepts such as business process re-engineering and virtual organisations are developed. These new types of organisation have more advanced and different requirements on their information technology (IT) support, since the relation between the organisation and its IT system is much tighter for these organisation types. We disucss potential problems of traditional IT approaches in these organisations. As an alternative, we propose a different perspective on the role of IT, i.e., we view the organisation as consisting of a physical and a virtual layer that both are active, equally important and contain models of each other.

    Small Island Developing States: Using the MSI for Strategic Sustainable Development2011Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This report is aimed at exploring what a Small Island Developing State (SIDS) would need to do in order to strategically use the Mauritius Strategy (MSI) to move their country towards sustainability as defined by the four principles of sustainability. Interviews were conducted with users and experts on the MSI representing various sectors such as governments, intergovernmental organisations and non-governmental organisations. These interviews were combined with document content analysis of key texts in order to identify strengths and necessary improvements of the MSI. A potential "ideal use" of the MSI was created by combining its current strengths and the Framework for Strategic Sustainable Development. This was then compared with the current reality of MSI usage, and gaps between the two were identified. Recommendations were given based on these gaps and on the improvements pointed out in the interviews in order to form a process through which a SIDS government could use the MSI to reach full sustainability.

    Den Urbana Trädgården: Ett självorganiserat stadsrum2013Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Grönstruktur och parker har betydelse för livsmiljön i en stad. Urbana trädgårdar och informell påverkan på grönstrukturen är en allt mer vanlig syn i städer. Ofta tar dessa verksamheter mark i anspråk utan att ägandeskap föreligger men rätten till marken kan med tiden förändras. Uppsatsen undersöker vilka motiv som ligger bakom initiativ till urbana trädgårdar genom fyra fallstudier i Berlin. Intervjuer med initiativtagare och deltagare undersöker om de urbana trädgårdarna är mötesplatser, hur de upplevs påverka sin omgivning och varför informanterna väljer att tillbringa tid i trädgårdarna. Diskussion av resultatet belyses genom teori kring offentliga platser, självorganisering, appropriering och rätten till staden samt en historisk jämförelse med koloniträdgårdsrörelsen. Uppsatsen visar att stadsinvånare har ett behov av kontakt med naturen, och att det behovet kan tillfredställas på ytor i staden som inte behöver vara stora. Trädgårdarna påverkar sin omgivning genom en förändrad dynamik av människor som rör sig på platserna de finns på. Dock är de en del av större förändringar som sker i dess omgivning. Urbana trädgårdar skiljer sig från parker på så sätt att de är inkluderande i formandet av platsen, vilket skapar positiva sociala effekter för de som deltar. De urbana trädgårdarna kan komplettera grönstrukturen, fylla tomma mellanrum i staden och är ett uttryck för att stadsinvånare inte nöjer sig med vad staden erbjuder utan själv förändrar den för att uppfylla sina behov.

    Sjuksköterskestudenters attityder till att vårda patienter med sjukdomen hiv: en intervjustudie2011Student thesis
    Abstract [sv]

    Bakgrund: I Sverige har det skett en ökning av sjukdomen humant immunbristvirus (hiv) sedan 2002 och det är idag cirka 400-500 personer som smittas varje år. Hiv anses vara en tabubelagd sjukdom som vårdpersonal kan förehålla sig olika till. Därför är det av betydelse att studera blivande sjuksköterskors attityder till att vårda patienter med hiv. Syfte: Syftet med studien var att studera sjuksköterskestudenters attityder till att vårda patienter med sjukdomen hiv. Metod: En semistrukturerad intervju genomfördes med åtta kvinnliga studenter i sista terminen på sjuksköterskeprogrammet våren 2011 på BTH. Intervjuerna analyserades med hjälp av Burnards tolkning av innehållsanalys. Resultat: Resultatet visade att sjuksköterskestudenter har en positiv attityd till att vårda patienter med hiv, men att det finns fördomar i vården och även en viss rädsla för att själv bli smittad av sjukdomen. Sjuksköterskestudenterna vill ha mer utbildning om hiv även om kunskapen hos dem är god. Studenterna ansåg att vården kan bli lidande om inte god kunskap om hiv finns hos sjuksköterskan då det finns risk för att det läggs mer fokus på sin egen ”försiktighet” än att samtala med patienten. Slutsats: Sjuksköterskestudenter i sista terminen på utbildningen anser att det skulle behövas mer kunskap genom utbildning till sjukdomen hiv och på så sätt skulle eventuellt fördomar och negativa attityder kunna minskas i vården.

    Development of the Culemborg goods yard, Cape Town, South Africa2009Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The aim of this minor field study was to produce a physical plan of the Culemborg goods yard in Cape Town, South Africa, with a distinct alignment towards sustainability for a middle to low income group. With the use of a Kevin Lynch analysis, a block analysis and analysis by Piet Louw the information that had been collected through inventory and study of previous projects of the site was processed. A SWOT-analysis summarized the analyses and from that a few keywords were derived. The keywords, such as pedestrian friendly, dense, integration, mix use, etc., were used as goals in the drafting of the physical plan for the goods yard. Through this a plan proposal was created for the whole area. The authors chose one area each within the plan to explore more deeply. This resulted in two situation plans, one for ‘the activity bridge’ and one for ‘the centre of Culemborg’.

    Närstående närvarande under återupplivning En litteraturstudie av sjuksköterskans upplevelse2014Student thesis
    Abstract [sv]

    Bakgrund: Efter en händelse på ett sjukhus under 1980-talet då en kvinna blev nekad till att stanna i rummet med sin närstående under ett återupplivningsförsök blev närvaron av närstående diskutabelt där det började ifrågasättas varför närstående nekades till att få stanna kvar i återupplivningsrummet. Internationellt har ett flertal organisationer satt upp riktlinjer gällande närstående närvaro under återupplivningsförsök som fortfarande inte tillämpas överallt. Studier visar på att sjuksköterskor har varierande uppfattningar om fördelar och nackdelar med att ha närstående närvarande under återupplivningsförsök, dock saknas sammanställningar gällande sjuksköterskors upplevelser av att ha patientens närstående närvarande under återupplivningsförsök. Syfte: Syftet med studien var att beskriva sjuksköterskans upplevelse av att ha patientens närstående närvarande under återupplivningsförsök. Metod: Litteraturstudie med kvalitativ ansats där analys skett med Graneheim och Lundman's (2004) tolkning av innehållsanalys. Studien bygger på sex vetenskapliga artiklar. Resultat: I resultatet framkom upplevelser där närstående påverkat återupplivningsförsöket genom att distrahera sjuksköterskorna och fått fokus att skifta från patienten till närstående. Det framkom upplevelser där närstående inte påverkat återupplivningsförsöket utan istället enbart gråtit och uppträtt lugnt. Ytterligare upplevelser som framkom i resultatet var att sjuksköterskorna ändrade uppfattning efter att närstående närvarat under patientens återupplivningsförsök. Uppfattningar som att närstående inte skulle förstå situationen ändrades efter att sjuksköterskorna fått uppleva närstående närvarande. Kommunikationen mellan närstående och sjuksköterskan är viktig för att kunna skapa en relation och i resultatet framkom att ytterligare en personal som stödjer närstående i återupplivningsförsöket hade underlättat kommunikationen och skapandet av en bra relation. Slutsats: Oerfarna sjuksköterskors uppfattningar om närstående närvarande under återupplivningsförsök överensstämde inte med upplevelserna som erfarna sjuksköterskor hade varit med om. Behovet av personal som kunde stödja närstående var också saknat. Det framkom upplevelser där närstående påverkat återupplivningsförsöket genom att distrahera sjuksköterskorna och upplevelser där närstående inte påverkat återupplivningsförsöket och inte varit en distraktion utan uppträtt lugnt.

    Integrating Push Technology with the Ericsson Mobile Positioning Center2001Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Push is an Internet technology, which allow people to subscribe to a content- or service provider that automatically update the subscriber?s computer or Personal Digital Assistant (PDA) with the latest information without having the subscriber to first request for new information. The Ericsson Mobile Positioning Center (MPC) is a gateway that provides geographical positions of mobile stations to various applications. This Master Thesis gives the reader an overview of these technologies and presents an alternative way in integrating a third part Push-solution with the MPC. The integration proposal is also evaluated against the current Push functionality that Ericsson has developed and integrated into the MPC.

    Webbaserad hälsokommunikation – och dess potential som informationskanal för primärprevention2012Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Syftet med studien var att belysa Internet-webbsidans potential som kanal för hälsokommunikation kring primärprevention, med utgångspunkt från en webbaserad vaccinationskampanj mot livmoderhalscancer. Studien är empirisk med en kvalitativ ansats. Enkäter och semistrukturerade gruppintervjuer med halvöppna frågor har använts för att samla in data. Fjorton unga kvinnor i åldern 18-19 år på två gymnasieskolor i Stockholm deltog i studien. För att analysera data har innehållsanalys med manifest ansats används. Resultaten visar att kvinnorna hade olika attityder till, samt uppfattningar och upplevelser av den webbaserade hälsokommunikationen och olika förbättringsområden framkom. Det gällde både informationens innehåll och struktur. Trots att man upplevde sig ha all kunskap i ämnet, från sina föräldrar, så framgick viss oförståelse av informationens budskap. Invändningar framkom kring informationens användbarhet och tillgänglighet, främst vad gäller för långa textstycken, otydliga länkar och rubriker samt oklar design. Samtidigt upplevdes informationen bidra till ökad kunskap i ämnet och positiva attityder till budskapet kunde identifieras. Dock framkom behov av mer information kring biverkningar och bemötande av negativ kritik mot vaccinationen. Webbaserad hälsokommunikation kring primärprevention borde ha stor potential för den här åldersgruppen eftersom de flesta använder Internet och eftersom det, i studien, framkom en viss brist på kunskap i ämnet. Men för att uppnå en framgångsrik webbaserad hälsokommunikation är det viktigt att försäkra att informationen är anpassad till målgruppens behov, så att den är användbar och tillgänglig för alla, samt att den engagerar föräldrar som är en viktig informationskälla för de unga kvinnorna. För att vaccinationskampanjens budskap ska nå ut till dem som inte finner den webbaserade kommunikationen tillfredsställande kan webbsidan med fördel kombineras med andra informationskanaler.

    Abstract [en]

    We find the Lie point symmetries of the Novikov equation and demonstrate that it is strictly self-adjoint. Using the self-adjointness and the recent technique for constructing conserved vectors associated with symmetries of differential equations, we find the conservation law corresponding to the dilation symmetry and show that other symmetries do not provide nontrivial conservation laws. Then we investigate the invariant solutions.

    Social Sustainability: Exploring the Role of Social Enterprises2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The degradation of the ecological and social systems has largely resulted from human activities that deplete natural resources and undermine human needs in society. Traditional business culture, driven mainly by profit maximization, is a factor that has worsened this sustainability challenge. Social enterprises (SEs) are a form of business that hold the potential to help make the transition towards a sustainable society. The purpose of this study is two-fold. First, it explores SE contributions to creating a sustainable social system. Second, it examines how SEs exhibit the dimensions of trustworthiness, leading to trusting relationships in society. Social sustainability principles (SSPs) define social sustainability and are drawn from the Framework for Strategic Sustainable Development. They are used as a foundation for identifying SE contributions. The researchers draw on experiences from social entrepreneurs and experts in the field of social entrepreneurship. SEs contribute at two levels: the individual level and the societal level. They break down barriers to the SSPs and provide opportunities to individuals with respect to the five principles. SEs operate based on a culture of impartiality and create opportunities for meaning for individuals in their target groups. They consistently take leaps of faith, believing in the trustworthiness of those who are otherwise deemed untrustworthy.

    Socialization in family firms: A model of managing family firms across generations2006Conference paper (Refereed)
    Abstract [en]

    Research in the area of family business aims to understand three primary issues: (1) how family firms are different from non-family firms, (2) what the competitive advantages for family firms are, and (3) how families can transfer knowledge about their competitive advantage between generations. In this paper we use the concept of family firm capital to differentiate competitive advantages of family and non-family firms, and to clarify what are the different types of knowledge that are important to transfer across generations of families. We also borrow from the socialization literature to provide a framework to explain how knowledge can be transferred across family generations and family employees. We discuss this model and present potential implications for family business research.

    A new spectral index for the extraction of built-up land features from Landsat 8 satellite imagery2018In: Geocarto International, ISSN 1010-6049, E-ISSN 1752-0762Article in journal (Refereed)
    Abstract [en]

    Extracting built-up areas from remote sensing data like Landsat 8 satellite is a challenge. We have investigated it by proposing a new index referred as Built-up Land Features Extraction Index (BLFEI). The BLFEI index takes advantage of its simplicity and good separability between the four major component of urban system, namely built-up, barren, vegetation and water. The histogram overlap method and the Spectral Discrimination Index (SDI) are used to study separability. BLFEI index uses the two bands of infrared shortwaves, the red and green bands of the visible spectrum. OLI imagery of Algiers, Algeria, was used to extract built-up areas through BLFEI and some new previously developed built-up indices used for comparison. The water areas are masked out leading to Otsu’s thresholding algorithm to automatically find the optimal value for extracting built-up land from waterless regions. BLFEI, the new index improved the separability by 25% and the accuracy by 5%.

    Leverage Points for Effective Cross-Sector Collaboration in Eco-municipalities: Looking at Eindhoven Case Study2013Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    There is an increasing acknowledgement in Eco-municipalities – cities using the Framework for Strategic Sustainable Development (FSSD) as a tool for their planning process – of the need for Cross-Sector Collaboration, but the necessary expertise is often lacking. The purpose of this study is to better understand effective CSC in Eco-municipalities through indicating potential leverage points and inform the use of the FSSD in this specific context. An 'effective CSC' lens is constructed from general CSC literature and documents from Eco-municipalities. 187 barriers and enablers to effective cross-sector collaboration are identified from interviews with experts and interviews from the In-depth Case Study in the city of Eindhoven. An 'Importance Index' defined by alignment with Lens Factors is developed to select key indicators. These key indicators are clustered into 45 potential leverage points for effective CSC in Eco-municipalities. The use of these potential leverage points is checked in an In-depth Case Study through a Causal Loop Diagram in which nine leverage points were identified. Interrelations between these leverage points, unexpected results and methodology are discussed, conclusions are drawn, and further research is suggested.

    Scalability of the Bitcoin and Nano protocols: a comparative analysis2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the past year cryptocurrencies have gained a lot of attention because of the increase in price. This attention has increased the number of people trading and investing in different cryptocurrencies which has lead to an increased number of transactions flowing through the different networks. This has revealed scalability issues in some of them, especially in the most popular cryptocurrency, Bitcoin. Many people are working on solutions to this problem. One proposed solution replaces the blockchain with a DAG structure. In this report the scalability of Bitcoin’s protocol will be compared to the scalability of the protocol used in the newer cryptocurrency, Nano. The comparison is conducted in terms of throughput and latency. To perform this comparison, an experiment was conducted where tests were run with an increasing number of nodes and each test sent different number of transactions per second from every node. Our results show that Nano’s protocol scales better regarding both throughput and latency, and we argue that the reason for this is that the Bitcoin protocol uses a blockchain as a global data-structure unlike Nano that uses a block-lattice structure where each node has their own local blockchain.

    Leveraging a More Sustainable Global Agricultural System: Improving Multinational Organizations' Capacities to Procure2013Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The procurement of agricultural commodities by multinational organizations has been identified as a leverage point for moving the global agricultural system towards sustainability. This study focuses on how multinational organizations can improve their capacities to procure more sustainably grown agriculture commodities. Using the Framework for Strategic Sustainable Development (FSSD) to create a theoretical ‘Ideal Case’ for procurement practices, this study analyzes the key strengths and weaknesses of existing practices surrounding the procurement of agricultural commodities in order to determine how they can improve. Interviews with four multinational corporations, one INGO and several experts in the field showed various weaknesses, including a lack of whole-system perspectives, inadequate definitions of sustainability, and weak strategies and tools to support organizations’ movements towards sustainability. Using these findings, recommendations were created to provide procurers, sourcing managers, supply chain managers, and sustainability managers with the necessary guidance to create conditions enabling the procurement of more sustainably grown agricultural commodities. The recommendations call for multi-stakeholder cooperation, increased use of impact assessments, long-term sustainability goals, and credible certification systems.

    Perspectives on Children amongst Planners in Beijing. A field study in Beijing, China.2011Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This thesis is focused on the perspectives on children held by urban planners in Beijing from an explorative approach. The aim is to investigate how planners in Beijing are considering children and the children’s perspective in the urban planning processes. My research is based on interviews with planners in Beijing and literature studies to achieve an understanding for what type of perspective on children that dominates among planners in Beijing. In addition to this, the environmental situation for children in Beijing has been researched through literature studies and observations, to enhance an understanding for children’s role in the Chinese society and Beijing’s urban environments. The interviews were performed in Beijing during the autumn of 2010 among six people involved in urban planning processes. The observations were performed in Beijing during the same time, predominantly in parks and hutong areas of Beijing. This report is based on the theoretical approaches of The child and urban environments, The urban planners and the perspective on children and The cultural, historical and contemporary context of China. The theoretical approaches are used in the analyses focused on the themes of Children in the urban public space in Beijing and The perspective on children among urban planners in Beijing. The result shows that the perspective on children among planners in Beijing today correspond to the perspective on children dominating urban planning processes in Europe during the 1960’s and 1970’s. These perspectives mean that in Beijing, children are not seen or used as active stakeholders in urban planning processes and the adult perspective on children is dominated by prioritizing children’s needs rather than their views and thoughts on their ambient environments. This derives from that in Beijing no sort of citizen participation is common. Therefore, neither are children asked to have their say during planning processes. Planning without citizen participation and with the main focus on the “expert planner” was the situation in many western countries in the 60’s and 70’s. This gives that the perspective on children among planners in Beijing today to some extent corresponds to the perspective among planners in Europe in past times. Today Beijing is undergoing radical urban changes due to of the rapid economical growth of China. This gives, that it is not only the political climate that affects the use of citizen participation, but also that private investors and their interest is dominating in the development processes.

    Differentiating simulations and real (remote) experiments2017In: ACM International Conference Proceeding Series, Association for Computing Machinery , 2017Conference paper (Refereed)
    Abstract [en]

    The more recent emergence of remote laboratories caused some discussions about their real educational value, when compared to traditional hands-on and virtual laboratories. This discussion is relevant because remote labs rely on computer-mediated access to real instruments and apparatus, being sometimes difficult to explain the difference between values obtained from real (remote) measurements and values obtained from computer simulations. This paper aims to evidence aspects that differentiate remote and virtual laboratories, by presenting two very simple experiments dealing with the characteristics of real instruments (limited bandwidth) and real circuits (electromagnetic interference). © 2017 Association for Computing Machinery.

    Workplace Health Promotion in Japan2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    The rapidly aging population in Japan constitutes a problem as public health expenditure is expected to increase. At the same time, the working part of the population is decreasing straining the health insurance scheme. Since the workplace is a setting that influences a large part of the adults for a long part of their lives, workplace health promotion has potential to improve the situation. This paper examines how workplaces in Japan are used for health promotion. Deductive content analysis is used to examine how workplace interventions are examined in the research literature. The findings suggest that there is considerable variation in workplace health promotion in Japan.

    Kvinnors upplevelser efter diagnostiserad bröstcancer.2010Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Bakgrund: En av de vanligaste cancerformerna hos kvinnor är bröstcancer. I Sverige diagnostiseras 15-20 kvinnor varje dag. För att kunna ge en god omvårdnad behövs det kunskap om kvinnornas olika upplevelser. Syfte: Syftet med studien var att belysa kvinnors upplevelser efter ställd bröstcancerdiagnos. Metod: En litteraturstudie baserad på vetenskapliga artiklar med kvalitativ ansats. Resultat: Fyra kategorier framkom som speglade kvinnornas upplevelser efter ställd bröstcancerdiagnos: Rädslor för döden, Kvinnans förändrade självbild, Behovet av gemenskap och samhörighet samt Tankar om framtiden. Slutsats: För att kunna se till den unika kvinnan och hennes behov är det viktigt att ha kunskap och kännedom kring de olika upplevelserna som följer med en bröstcancerdiagnos.
