Factors in Fraudulent Emails that Deceive Elderly People2017Ingår i: Human Aspects of IT for the Aged Population. Aging, Design and User Experience: Proceedings, Part I / [ed] Jia Zhou, Gavriel Salvendy, Springer, 2017, 360-368 s.Konferensbidrag (Refereegranskat)

Fraud over the Internet is an increasingly common phenomenon and very common in the form of emails. Though new forms of fraud appear, it is important to look at common denominators that have so far come to light, and try to determine how they should be addressed in order to create a safer stay for everyone on the Internet. With this as motivation, and with a special eye to groups that may be considered especially vulnerable, this study aims to investigate what factors in fraudulent emails that people aged 65 and older have difficulty identifying when they meet them.

The increasing use of the Internet, the target group’s vulnerability, and the increasing use of technology in everyday life imply that this kind of fraud is likely to be borne by society to an ever increasing extent. These factors paint a disturbing picture of how the situation is today and the direction in which the phenomenon is headed. It is therefore of interest to clarify which factors come into play in successful attacks against the target group in order to target countermeasures against this form of fraud. To accomplish this, a survey was conducted among residents of a nursing home and members of a Swedish national senior citizen organisation. The results from 122 respondents to our digital questionnaire show that the importance of technical factors in fraudulent email needs to be clarified for the studied group in order for them to make better, accurate assessments of the emails that they meet. The most common factor that the respondents failed to identify were links in the email that looked untrustworthy.

Navigating complexity through knowledge coproduction: Mainstreaming ecosystem services into disaster risk reduction2015Ingår i: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 112, nr 24, 7362-7368 s.Artikel i tidskrift (Refereegranskat)

Achieving the policy and practice shifts needed to secure ecosystem services is hampered by the inherent complexities of ecosystem services and their management. Methods for the participatory production and exchange of knowledge offer an avenue to navigate this complexity together with the beneficiaries and managers of ecosystem services. We develop and apply a knowledge coproduction approach based on social-ecological systems research and assess its utility in generating shared knowledge and action for ecosystem services. The approach was piloted in South Africa across four case studies aimed at reducing the risk of disasters associated with floods, wildfires, storm waves, and droughts. Different configurations of stakeholders (knowledge brokers, assessment teams, implementers, and bridging agents) were involved in collaboratively designing each study, generating and exchanging knowledge, and planning for implementation. The approach proved useful in the development of shared knowledge on the sizable contribution of ecosystem services to disaster risk reduction. This knowledge was used by stakeholders to design and implement several actions to enhance ecosystem services, including new investments in ecosystem restoration, institutional changes in the private and public sector, and innovative partnerships of science, practice, and policy. By bringing together multiple disciplines, sectors, and stakeholders to jointly produce the knowledge needed to understand and manage a complex system, knowledge coproduction approaches offer an effective avenue for the improved integration of ecosystem services into decision making.

Medborgardialog i Sollentuna kommun2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)

Abstract

Medborgardialog i Sollentuna kommun Författare: Ruby Sarhangi

Sveriges Kommuner och Landsting har i samarbete med regeringen startat projekt medborgardialog för att utveckla medborgarnas delaktighet och engagemang i kommunpolitiken. Denna studie syftar till att undersöka vilka uppfattningar det råder kring begreppet medborgardialog i Sollentuna kommun bland politiker, tjänstemän och medborgare. Uppsatsen ämnar även att undersöka vilka förväntningar politiker, tjänstemän och medborgare har på varandra samt vilka kunskaper respektive grupp har om projekt medborgardialog.

Den teoretiska ramen redogör för olika demokratimodeller som därefter följs av en redogörelse för samhällsinformation och avslutas sedan med teori om internkommunikation. Metoden som har använts i denna uppsats är kvalitativa intervjuer. Semistrukturerade intervjuer har genomförts med elva informanter varav fyra politiker, två tjänstemän och fem medborgare i Sollentuna kommun.

Den empiriska analysen utgår ifrån tre övergripande teman, definition, kunskap och förväntning på medborgardialog utifrån politiker, tjänstemän och medborgarnas syn. Undersökningen visar att det råder olika definitioner av medborgardialog bland samtliga informanter. Studien visar att medborgarna inte har kunskaper om medborgardialog och tjänstemännen indikerar på att politikerna saknar kunskap om projekt medborgardialog. Samtliga informanter har förväntningar på varandra. Efter att medborgarna fick reda på att Sollentuna kommun kommer att påbörja projekt medborgardialog ökade deras förväntningar på den politiska ledningen.  Politikerna å andra sidan förväntar sig att medborgarna deltar i möten och engagerar sig för att projektet ska vara levande. Tjänstemännen förväntar sig att politikerna ger de direktiv och riktlinjer för att de ska kunna implementera projekt medborgardialog.

Nyckelord: Medborgardialog, kunskap, förväntningar, politiker, tjänstemän, medborgare

Computer simulations of condensed phases with icosahedral local order2001Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)

Understanding the fundamental aspects, and the formation mechanisms of glasses remains an outstanding unsolved problem of condensed-matter physics.

Glass-formation in simple atomic systems is generally associated with the icosahedral local order. In this study, different aspects of the liquid-glass transition are investigated in a computer simulation using a model system with predominantly icosahedral local order. We demonstrate that the dramatic slowing down of the relaxation dynamics observed in this system when approaching the glass transition from the liquid phase, and the eventual structural arrest are related to a structural transformation which is recognized as formation of a percolating cluster composed of icosahedra. It is concluded that the rapid cluster growth is inherently related to the tendency for low-dimensional cluster geometry induced by the particular form of the pair potential. A model is suggested interpreting the characteristic dynamical anomalies commonly associated with supercooled liquid dynamics, including breaking the Stokes-Einstein relation, as arising from the long-time decomposition of the relevant phase-space region. This decomposition, caused by the development of long-range clusters, is also manifested in growing cooperativity of diffusive dynamics.

Another part of this study concerns the vibrational dynamics in a glass formed by the investigated model from the liquid state. We analyze the glass dynamics by comparing it with dynamics of the $\sigma$ phase, a Frank-Kasper crystal which is morphologically related to this glass and can possibly be regarded as the crystalline ground state for this system. The structural similarity of the $\sigma$ phase with this glass is also revealed by using the wavelet analysis of pair-correlation functions. The pattern of vibrational dynamics in this glass is found to be distinctly different from that in the glass formed using the Lennard-Jones potential. It is demonstrated that these distinctions can be accounted for by considering the vibrational dynamics in the respective crystalline phases.

In order to facilitate the computational studies of extremely slow dynamics of supercooled liquids, we have developed an efficient, cache coherent and parallelizable molecular dynamics algorithm. This algorithm was implemented for a shared memory symmetric multi-processor architecture using OpenMP directives. A large number of auxiliary utilities has been created or adapted for the analysis of the data from our molecular dynamics simulations.

Extracting Clinical Findings from Swedish Health Record Text2014Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)

Information contained in the free text of health records is useful for the immediate care of patients as well as for medical knowledge creation. Advances in clinical language processing have made it possible to automatically extract this information, but most research has, until recently, been conducted on clinical text written in English. In this thesis, however, information extraction from Swedish clinical corpora is explored, particularly focusing on the extraction of clinical findings. Unlike most previous studies, Clinical Finding was divided into the two more granular sub-categories Finding (symptom/result of a medical examination) and Disorder (condition with an underlying pathological process). For detecting clinical findings mentioned in Swedish health record text, a machine learning model, trained on a corpus of manually annotated text, achieved results in line with the obtained inter-annotator agreement figures. The machine learning approach clearly outperformed an approach based on vocabulary mapping, showing that Swedish medical vocabularies are not extensive enough for the purpose of high-quality information extraction from clinical text. A rule and cue vocabulary-based approach was, however, successful for negation and uncertainty classification of detected clinical findings. Methods for facilitating expansion of medical vocabulary resources are particularly important for Swedish and other languages with less extensive vocabulary resources. The possibility of using distributional semantics, in the form of Random indexing, for semi-automatic vocabulary expansion of medical vocabularies was, therefore, evaluated. Distributional semantics does not require that terms or abbreviations are explicitly defined in the text, and it is, thereby, a method suitable for clinical corpora. Random indexing was shown useful for extending vocabularies with medical terms, as well as for extracting medical synonyms and abbreviation dictionaries.

Utilizing Consumer Preferences to Promote Values Awareness in Information Systems Development2016Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)

The challenges of developing the information systems (IS) that support modern enterprises are becoming less about engineering and more about people. Many of the technical issues of the past, such as hardware size and power, connectivity, and robust software, are engineering problems that have largely been solved. In the next stage of computing, the human factor will be far more important than it has been in the past: the colors of an interface or the shape of an icon are the engineering problems of the past, and the availability and usefulness of such basic solutions is rapidly coming to a close. A new paradigm is needed that provides a roadmap of higher level conceptions and values, one about humane computing.

A part of this older, mechanistic approach are quantitative, economic values whose impact on IS are readily visible and acknowledged within software engineering. However, qualitative values, and in particular consumer preferences, have been researched to a lesser degree, and there has been very little direct application.  To create the next-generation information systems, requirements engineers and systems developers need new methods to capture the real preferences of consumers, conceptualize these abstract concepts, and then relate such preferences to concrete requirements for information systems.

To address this problem, this thesis establishes a conceptual link between the preferences of consumers and system requirements by accommodating the variations between them and expressing them via a conceptual model. Modeling such preferences and values so that they can be used as requirements for IS development is the primary contribution of this work. This is accomplished via a design science research paradigm to support the creation of the works’ primary artifact—the Consumer Preference-aware Meta-Model (CPMM).

CPMM is intended to improve the alignment between business and information systems by capturing and concretizing the real preferences of consumers and then expressing such preferences via the requirements engineering process, with the eventual output being information systems. CPMM’s development relies on theoretical research contributions within three areas in information systems—Business Strategy, Enterprise Architecture, and Requirements Engineering—whose relationships to consumer values have been under-researched and under-applied.

The case studies included in this thesis each demonstrate the significance of consumer preferences to each of these three areas.  In the first, a set of logical mappings between CPMM and a common approach to business strategy (strategy maps/balanced scorecards) is produced. In the second, CPMM provides the conceptual undergirding to process a massive amount of unstructured consumer-generated text to generate system requirements for the airline industry. In the concluding case, an investigation of foreign and domestic students at Swedish universities is structured through CPMM, one that first discovers the requirements for a consumer preference-based online education and then produces feature models for such a software product line-based system. The significance of CPMM as a lens for discovering new concepts and highlighting important information within consumer preference data is clearly seen, and the usefulness of the meta-model is demonstrated by its broad and beneficial applicability within information systems practice and research.

This thesis is about how to design Computer Supported Cooperative Work systems (CSCW) on the basis of design practice that is established in the Scandinavian model of System Design. The approach of the thesis is to develop an understanding of the design of CSCW environments through a series of case studies. These case studies, the CoDesk system, the AtWork system and the VideoCafe system, cover a variety of methods from the Scandinavian tradition in cooperative design. Studying how these methods have succeeded has been the primary source of inspiration for my thesis. In particular, this thesis will focus on the following issues: Can simulation of realistic work situations be used for cooperative design of CSCW systems by developers and users? And, how can we balance a design based on daily work practice with exploration of innovative CSCW solutions? Furthermore we are also investigating how cooperative design could be integrated in the evolving use and how to combine different design approaches into a coherent design. Given the complexity of CSCW it will be argued that the design of CSCW system needs to mix design methods with various backgrounds, such as methods that have their roots in workplace practice with methods that transcend common styles of cooperation, to balance different design methods' strengths and weaknesses. It is suggested that a usable approach is to define and use different design orientations in order to deal with this complexity. The use of a design orientation helps in selecting the essential element that is at the heart of the design. This approach seems more usable than working with pure design methods with specific outlines. A design orientation integrates instead a holistic view into the design by leaving the pre-dominant sequential notion in system modeling.

ICT4D Donor Agencies and Networks2015Ingår i: The International Encyclopedia of Digital Communication and Society; 1: A - K / [ed] Robin Mansell and Peng Hwa Ang, Chichester: Wiley-Blackwell, 2015, 1, 1-9 s.Kapitel i bok, del av antologi (Refereegranskat)

Information and communication technology for development (ICT4D) evolved as a field of development cooperation in conjunction with the World Summit on the Information Society (WSIS) in 2003 and 2005. Prior to this United Nations summit, few donors were involved in ICT4D, but as policymakers around the world became involved in the WSIS process, ICT4D emerged as an important aspect of the global development agenda. Donors started to recognize that ICT offered a tool for development, not least for the achievement of the Millennium Development Goals (MDGs). After the WSIS interest dwindled among leading donor agencies, but resurfaced as mobile technologies became widespread even in income-poor countries and among poor populations and after the digitally mediated social uprisings of the so-called Arab Spring which highlighted the social and political significance of the internet. New actors are becoming involved including philanthropic organizations, while the ICT4D field continues to explore new working methods like multistakeholder partnerships. Meanwhile, ICT is gradually becoming integrated into development efforts, although global patterns of digital stratification still remain to be overcome. This entry focuses on the roles of donor organizations and their networks

Shades of Certainty: Annotation and Classification of Swedish Medical Records2012Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)

Access to information is fundamental in health care. This thesis presents research on Swedish medical records with the overall goal of building intelligent information access tools that can aid health personnel, researchers and other professions in their daily work, and, ultimately, improve health care in general.

The issue of ethics and identifiable information is addressed by creating an annotated gold standard corpus and porting an existing de-identification system to Swedish from English. The aim is to move towards making textual resources available to researchers without risking exposure of patients’ confidential information. Results for the rule-based system are not encouraging, but results for the gold standard are fairly high.

Affirmed, uncertain and negated information needs to be distinguished when building accurate information extraction tools. Annotation models are created, with the aim of building automated systems. One model distinguishes certain and uncertain sentences, and is applied on medical records from several clinical departments. In a second model, two polarities and three levels of certainty are applied on diagnostic statements from an emergency department. Overall results are promising. Differences are seen depending on clinical practice, annotation task and level of domain expertise among the annotators.

Using annotated resources for automatic classification is studied. Encouraging overall results using local context information are obtained. The fine-grained certainty levels are used for building classifiers for real-world e-health scenarios.

This thesis contributes two annotation models of certainty and one of identifiable information, applied on Swedish medical records. A deeper understanding of the language use linked to conveying certainty levels is gained. Three annotated resources that can be used for further research have been created, and implications for automated systems are presented.

Fine-grained Certainty Level Annotations Used for Coarser-grained E-health Scenarios: Certainty Classication of Diagnostic Statements in Swedish Clinical Text2012Ingår i: Proceedings of the 13th international conference on Computational Linguistics and Intelligent Text Processing - Volume Part II / [ed] Alexander Gelbukh, Berlin/Heidelberg: Springer Berlin/Heidelberg, 2012, 450-461 s.Konferensbidrag (Refereegranskat)

An important task in information access methods is distinguishingfactual information from speculative or negated information.Fine-grained certainty levels of diagnostic statements in Swedish clinicaltext are annotated in a corpus from a medical university hospital.The annotation model has two polarities (positive and negative) andthree certainty levels. However, there are many e-health scenarios wheresuch ne-grained certainty levels are not practical for information extraction.Instead, more coarse-grained groups are needed. We presentthree scenarios: adverse event surveillance, decision support alerts andautomatic summaries and collapse the ne-grained certainty level classi-cations into coarser-grained groups. We build automatic classiers foreach scenario and analyze the results quantitatively. Annotation discrepanciesare analyzed qualitatively through manual corpus analysis. Ourmain ndings are that it is feasible to use a corpus of ne-grained certaintylevel annotations to build classiers for coarser-grained real-worldscenarios: 0.89, 0.91 and 0.8 F-score (overall average).

Empowering women through ICT2012Rapport (Övrigt vetenskapligt)

Informations- och kommunikationsteknologier (IKT) är nära kopplade till social och ekonomisk utveckling. Potentialen att främja social förändring kräver att alla har tillgång till dessa teknologier. Den utbredda ojämlikheten i tillgång till IKT pekar på att sociala och ekonomiska omständigheter utgör ett hinder för många grupper att utnyttja dessa teknologier. Empiriska studier har även visat att kvinnor världen över har sämre tillgång till IKT  än män. Denna diskrepans kallas ofta den digitala genusklyftan. Om tillgång till IKT r ska bidra till  hållbar social och ekonomisk utveckling  måste en stor del av jordens befolkning av kvinnor få stöd genom riktade insatser.

Denna publikation är en granskning av Spiderprojekt som fokuserat på kvinnor och IKT. Spider har finansierat ett flertal projekt med avsikt att öka användningen av IKT  bland kvinnor och genom detta öka deras möjlighet till självbestämmande. Insatserna har fokuserat på aktiviteter i  vardagen och resultat visar att framgång var starkt kopplad till hur väl dessa teknologier anpassades till kvinnornas vardag och inte tvärt om.

Designing Online Courses for Individual and Collaborative Learning: A study of a virtual learning environment based in Sri Lanka2015Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)

Online courses of distance learning programmes at universities are designed considering the characteristics and needs of their adult learners. Basically, there are two types of learners in an online course: individual learners and collaborative learners. Designing for learner satisfaction and learning effectiveness for both types of learners is challenging. In fact, previous research has noted that many online courses fail due to poor design. As a solution, researchers have identified instructional design principles that can guide the design of successful online courses. However, these principles lack detailed information to apply them in contexts different from where they had been identified. This consideration raises a question: how does one adapt the existing design principles to design online courses that promote both individual and collaborative learning, particularly in contexts where online courses are supposed to be conducted with minimal teacher support? In the present research, this question is addressed via two sub-research questions: (1) which course components and their design features can promote learners’ satisfaction, perceived learning, and learning effectiveness, and (2) which course components and their design features can stimulate inquiry-based learning and peer-teaching? The research was carried out in the field of educational design research with sets of students and instructional designers of a virtual learning environment prepared for a university-level degree programme in Sri Lanka. Referring to the findings of this research, the thesis discusses how to design online courses that promote both individual and collaborative learning. Further, based on the findings, the thesis presents a set of design principles and guidelines to promote both individual and collaborative learning in online courses that are on information technology related subjects and prepared for distance learning programmes.

Inclusive Digital Socialisation: Designs of Education and Computer Games in a Global Context2017Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)

Digital socialisation is to learn the ways of living online, across national borders, local cultures and societies and has to be inclusive for equal participation. Conditions for this socialisation process are different due to both local and individual limitations. In a high-income country like Sweden, playing computer games are one of the most common practices for digital socialisation among youth online (digital youth), but rarely in school with teachers. Thus, there is limited institutionalised support taking responsibility for the socialisation process online of digital youth. As contrast, in a lower middle-income country like Sri Lanka, telecentres provide holistic community services with free access to computer hardware and sometimes also Internet to bridge an internal digital divide. However, there are still several barriers for inclusive digital socialisation, such as shortage of teachers, infrastructure, accessibility and a language barrier. The problem is that digital youth have to overcome barriers for inclusive digital socialisation, often with limited institutionalised support. Game oriented education (GOE) is a potential approach to bridge these barriers. Thematic questions were: How can environments for inclusive digital socialisation be designed for digital youth who: T1) are gamers that are excluded in school; T2) are living in underprivileged communities; and/or T3) have disabilities and play games? A related thematic main question is: T4) how can education about game accessibility be designed for game developers? Within a design science framework, ethnography showed that GOE with entertainment games enabled gamers excluded in Swedish schools to be included, but could not be sustained by the schools. GOE workshops about programming were a possible way to raise awareness about ICT opportunities at Sri Lankan telecentres. Furthermore, a game prototype for deaf versus blind was demonstrated in workshops within formal education settings in Sweden and Sri Lanka, exploring a design method. Finally, two international online surveys provided data for designing a game accessibility curriculum framework, based upon opinions from researchers and game developers. Conclusions are that GOE may be an environment for inclusive digital socialisation, if it is: 1) sustained in the educational social system; 2) enabled within limits of ICTD; and 3) accessible for digital youth with disabilities. The latter requires: 4) education for game developers. This thesis shows how these requirements may be fulfilled, enabling GOE as a design to achieve inclusive digital socialisation in a global context.

Integration of Enterprise Modeling and Model Driven Development: A Meta-Model and a Tool Prototype2014Licentiatavhandling, monografi (Övrigt vetenskapligt)

The use of models for designing and developing Information Systems (IS) has changed in recent years. Models are no longer considered a peripheral documentation medium that is poorly maintained and often neglected. Rather, models are increasingly seen as essential parts of the final product—as central artifacts that drive and guide the development efforts. The knowledge that modelers rely on when designing models is represented as formal models and clearly defined rules for transforming the models. The flexibility, reliability, and effectiveness offered by the formal models and the transformations are making Model Driven Development (MDD) a popular choice for building IS. Models also serve in describing enterprise design, where enterprise-level models capture organizational knowledge and aid in understanding, improving, and growing the enterprise. Enterprise Modeling (EM) offers a structured and unified view of the enterprise, thereby enabling more informed and accurate decisions to be made.

Many MDD approaches have been proposed to tackle a wide range of IS-related issues, but little attention is being paid to the source of the knowledge captured by the IS models. EM approaches capture organizational knowledge and provide the necessary input and underlying context for designing IS. However, the results produced by EM approaches need to be manually analyzed by modelers to create the initial MDD model. This interruption of the MDD process represents a gap between enterprise models and MDD models. Limited research has been done to connect EM to MDD in a systematic and structured manner based on the principles of model-driven development.

This thesis proposes a unifying meta-model for integrating EM and MDD. The meta-model captures the inherent links that exist between organizational knowledge and IS design. This helps to improve the alignment between organizational goals and the IS that are created to support them. The research presented herein follows the guidelines of the design science research methodology. It starts with a state-of-the-art survey of the current relationship between MDD and prior stages of development. The findings of the survey are used to elicit a set of necessary properties for integrating EM and MDD. The unifying meta-model is then proposed as the basis for an integrated IS development approach that applies the principles of MDD and starts on the enterprise level by considering enterprise models in the development process. The design of the meta-model supports the elicited integration properties. The unifying meta-model is based on the Enterprise Knowledge Development (EKD) approach to EM. A prototype tool is developed to support the unifying meta-model, following a study to choose a suitable implementation environment. The use of the unifying meta-model is demonstrated through the implemented tool platform using an example case study, revealing its advantages and highlighting the potential for improvement and future development.

Panoramic Video: Design Challenges and Implications for Content Interaction2013Ingår i: EuroITV '13: Proceedings of the 11th european conference on Interactive TV and video, New York: Association for Computing Machinery (ACM), 2013, 153-162 s.Konferensbidrag (Refereegranskat)

In this paper we explore viewing and interaction in an emerging type of interactive TV, where viewers are presented with panoramic ultrahigh-definition video combined with extensive interactive control over view selection. Instead of delivering only what will be consumed, emerging TV services offer high- resolution panoramic video to the viewers, enabling them to more freely explore the broadcast content by selecting regions of interest and navigating within the larger panoramic image. However, as we open up the television space both in field of view and in terms of the freedom given to viewers, new interactional challenges emerge. We have done user studies on two systems for interacting with panoramic high-resolution video, one based on the tablet interaction and other on the gesture interaction. Our findings revealed a number of design challenges concerning properties specific to panoramic video. Based on findings from the user studies and the identified design challenges, we have compiled a set of the design recommendations on how to support interactive viewing of panoramic content.

The art of discovering - experiences of novice researchers2016Ingår i: Qualitative Research Journal, ISSN 1443-9883, Vol. 16, nr 2, 125-137 s.Artikel i tidskrift (Refereegranskat)

Purpose - The purpose of this paper is to conceptualize and analyze novice researchers' experiences of the Glaserian grounded theory methodology. Design/methodology/approach - The grounded theory analytical procedures were applied. Findings - The paper suggests that the creative freedom inherited in the Glaserian grounded theory approach empowers novice researchers, and many students reported positive emotions related to this freedom. At the same time, this freedom can represent a difficulty. Several students thought the tabula rasa instruction was something of a paradox, and the instructions within the methodology to be without preconceptions, let the theory emerge, and find the social process was difficult for most students to understand. However, some students found that they could counteract this difficulty via a systematic coding process and by working in pairs that enabled them to conduct an analytical dialogue. Originality/value - This is the first study that investigates the way that novice researchers experience the Glaserian grounded theory methodology.

Television Practices: Ethnography, Television and User Practices2014Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)

This thesis explores television practices in a time when new technology has made it possible to interact with and create your own TV content. The work is focused on how user practices need to be understood in a context of chan- ging technology. The practices studied also show the relevance of ethno- graphic methods, and especially the wide spectrum of these different meth- ods within the field of Human-Computer Interaction. We distinguish be- tween sociologically informed ethnography and anthropological ethnogra- phy. Two questions are addressed: how can new forms of television practices be understood by means of different ethnographic methods, and, on a wider level, what method can we use for analysing methods in ethnographic re- search? Because ethnographic methods are qualitative, we have also chosen to use an open and qualitative approach when analysing them. Through comparing our different methods – their data and findings on one specific topic – we have discovered the differences between the methodological ap- proaches.
