    Accelerating difficulty estimation for conformal regression forests2017In: Annals of Mathematics and Artificial Intelligence, ISSN 1012-2443, E-ISSN 1573-7470, Vol. 81, no 1-2, p. 125-144Article in journal (Refereed)
    Abstract [en]

    The conformal prediction framework allows for specifying the probability of making incorrect predictions by a user-provided confidence level. In addition to a learning algorithm, the framework requires a real-valued function, called nonconformity measure, to be specified. The nonconformity measure does not affect the error rate, but the resulting efficiency, i.e., the size of output prediction regions, may vary substantially. A recent large-scale empirical evaluation of conformal regression approaches showed that using random forests as the learning algorithm together with a nonconformity measure based on out-of-bag errors normalized using a nearest-neighbor-based difficulty estimate, resulted in state-of-the-art performance with respect to efficiency. However, the nearest-neighbor procedure incurs a significant computational cost. In this study, a more straightforward nonconformity measure is investigated, where the difficulty estimate employed for normalization is based on the variance of the predictions made by the trees in a forest. A large-scale empirical evaluation is presented, showing that both the nearest-neighbor-based and the variance-based measures significantly outperform a standard (non-normalized) nonconformity measure, while no significant difference in efficiency between the two normalized approaches is observed. The evaluation moreover shows that the computational cost of the variance-based measure is several orders of magnitude lower than when employing the nearest-neighbor-based nonconformity measure. The use of out-of-bag instances for calibration does, however, result in nonconformity scores that are distributed differently from those obtained from test instances, questioning the validity of the approach. An adjustment of the variance-based measure is presented, which is shown to be valid and also to have a significant positive effect on the efficiency. For conformal regression forests, the variance-based nonconformity measure is hence a computationally efficient and theoretically well-founded alternative to the nearest-neighbor procedure.

    Evaluation of a Variance-Based Nonconformity Measure for Regression Forests2016In: Conformal and Probabilistic Prediction with Applications: 5th International Symposium, COPA 2016, Madrid, Spain, April 20-22, 2016, Proceedings / [ed] Alexander Gammerman, Zhiyuan Luo, Jesús Vega, Vladimir Vovk, Springer, 2016, p. 75-89Conference paper (Refereed)
    Abstract [en]

    In a previous large-scale empirical evaluation of conformal regression approaches, random forests using out-of-bag instances for calibration together with a k-nearest neighbor-based nonconformity measure, was shown to obtain state-of-the-art performance with respect to efficiency, i.e., average size of prediction regions. However, the use of the nearest-neighbor procedure not only requires that all training data have to be retained in conjunction with the underlying model, but also that a significant computational overhead is incurred, during both training and testing. In this study, a more straightforward nonconformity measure is investigated, where the difficulty estimate employed for normalization is based on the variance of the predictions made by the trees in a forest. A large-scale empirical evaluation is presented, showing that both the nearest-neighbor-based and the variance-based measures significantly outperform a standard (non-normalized) nonconformity measure, while no significant difference in efficiency between the two normalized approaches is observed. Moreover, the evaluation shows that state-of-the-art performance is achieved by the variance-based measure at a computational cost that is several orders of magnitude lower than when employing the nearest-neighbor-based nonconformity measure.

    Virtual patient simulation for learning and assessment: superior results in comparison with regular course exams2010In: Medical Teacher, ISSN 0142-159X, Vol. 32, no 10, p. 845-850Article in journal (Refereed)
    Abstract [en]

    

    Background: Our study aimed to observe the differences in assessment results between virtual patient simulation (VPS) and regular course exams in an Internal Medicine course for undergraduate medical students.

    Methods: Four cohorts of students (n = 216) used: a VPS or lectures for learning (terms 1 and 2); VPS and lectures or only lectures (term 3); and a paired set-up with both VPS and lectures (term 4). The assessment results, measured with both a VPS-based exam and a paper-based exam, were compared. A scoring rubric (0–6), developed and validated for the purpose of the trial, was applied to both types of assessment. Mean score differences of the results were compared for the four cohorts.

    Results: Both VPS and regular examination results were significantly higher in the VPS group compared to regular exam group (p < 0.001) in terms 1, 2 and 3. The paired mean difference in term 4 was 0.66 (95% confidence interval (CI) 0.50, 0.83; p < 0.001) for haematology and 0.57 (95% CI 0.45, 0.69; p < 0.001) for cardiology.

    Conclusion: Our findings suggest that using VPS both for learning and for assessment supports learning. VPS are better than traditional assessment methods when the virtual application is used for both learning and evaluation.

    Virtual patient simulation: knowledge gain or knowledge loss?2010In: Medical Teacher, ISSN 0142-159X, Vol. 32, no 7, p. 562-568Article in journal (Refereed)
    Abstract [en]

    Background: Virtual patients (VPs), high-fidelity simulators and standardized patients are powerful educational interventions leading to effective learning and supporting knowledge retention.

    Aim: This study explored the variations in retention with VP versus regular learning activities.

    Method: We conducted a randomized controlled study on early and delayed assessment results of 49 students using VP for learning and examination of haematology and cardiology topics in an Internal Medicine course, by means of a 0–10 scoring rubric.

    Results: The mean difference for early assessment with VP (study – control mean score) was 1.43 (95% confidence interval (CI) 0.96, 1.91; p < 0.001) for haematology and 1.34 (95% CI 0.93, 1.76; p < 0.001) for cardiology. In regular exams, the mean score difference was 2.21 (95% CI 1.3, 3.1; p < 0.001) and 1.52 (95% CI 0.76, 2.28; p < 0.001), respectively. With delayed assessments, the difference in mean score for Web-SP was 1.48 (95% CI 1.09, 1.86; p < 0.001), haematology and 1.16 (95% CI 0.74, 1.58; p < 0.001), cardiology; for regular exams the figures were 1.96 (95% CI 0.93, 2.98; p < 0.001) and 1.74 (95% CI 0.89, 2.58; p < 0.001). The effect size ranged from 0.5 to 0.8.

    Conclusion: Our results indicate better retention with VP than with traditional learning methods.

    Virtual Patient Simulation: what do students make of it?: A focus group study2010In: BMC Medical Education, ISSN 1472-6920, E-ISSN 1472-6920, Vol. 10, no 91Article in journal (Refereed)
    Abstract [en]

    Background

    The learners' perspectives on Virtual Patient Simulation systems (VPS) are quintessential to their successful development and implementation. Focus group interviews were conducted in order to explore the opinions of medical students on the educational use of a VPS, the Web-based Simulation of Patients application (Web-SP).

    Methods

    Two focus group interviews-each with 8 undergraduate students who had used Web-SP cases for learning and/or assessment as part of their Internal Medicine curriculum in 2007-were performed at the Faculty of Medicine of Universidad el Bosque (Bogota), in January 2008. The interviews were conducted in Spanish, transcribed by the main researcher and translated into English. The resulting transcripts were independently coded by two authors, who also performed the content analysis. Each coder analyzed the data separately, arriving to categories and themes, whose final form was reached after a consensus discussion.

    Results

    Eighteen categories were identified and clustered into five main themes: learning, teaching, assessment, authenticity and implementation. In agreement with the literature, clinical reasoning development is envisaged by students to be the main scope of VPS use; transferable skills, retention enhancement and the importance of making mistakes are other categories circumscribed to this theme. VPS should enjoy a broad use across clinical specialties and support learning of topics not seen during clinical rotations; they are thought to have a regulatory effect at individual level, helping the students to plan their learning. The participants believe that assessment with VPS should be relevant for their future clinical practice; it is deemed to be qualitatively different from regular exams and to increase student motivation. The VPS design and content, the localization of the socio-cultural context, the realism of the cases, as well as the presence and quality of feedback are intrinsic features contributing to VPS authenticity.

    Conclusions

    Five main themes were found to be associated with successful VPS use in medical curriculum: Learning, Teaching, Assessment, Authenticity and Implementation. Medical students perceive Virtual Patients as important learning and assessment tools, fostering clinical reasoning, in preparation for the future clinical practice as young doctors. However, a number of issues regarding VPS design, authenticity and implementation need to be fulfilled, in order to reach the potential educational goals of such applications.

    As time goes by: stakeholder opinions on the implementation and use of a virtual patient simulation system2010In: Medical Teacher, ISSN 0142-159X (print), 1466-187X (electronic), Vol. 32, no 11, p. e509-516Article in journal (Refereed)
    Abstract [en]

    Background: Stakeholder opinions on the implementation of a particular virtual patient application might prove important for decision-making and implementation efforts in general. This study aimed to capitalize on experiences originated from two postimplementation settings of Web-based Simulation of Patients (Web-SP). Method: We conducted a cross-sectional survey of stakeholder opinions (39 students, teachers, course directors, and university leaders) on the implementation and use of Web-SP in Colombia and Sweden, using a mixed method approach. Results: The respondents did not show equal preference in rating the ranking of the order of importance included in the variables (Friedman’s Chi square: 26.5 to 115.1, df=6, p <0.001, Kendall’s coefficient of concordance ranging from 0.11 to 0.50). The answers provided as free comments supported the statistical findings on the importance of end-user customization, need for authenticity in software design, and use of virtual patient simulations in a curricular context, for clinical reasoning development. Conclusions: Virtual Patient design should allow extensive editing, support case authenticity and enhance clinical reasoning abilities, in an effort for ensuring accountability and sustainable development of the field.

    Robust spoken language understanding in a computer game2006In: Speech Communication, ISSN 0167-6393, E-ISSN 1872-7182, Vol. 48, no 3-4, p. 335-353Article in journal (Refereed)
    Abstract [en]

    We present and evaluate a robust method for the interpretation of spoken input to a conversational computer game. The scenario of the game is that of a player interacting with embodied fairy-tale characters in a 3D world via spoken dialogue (supplemented by graphical pointing actions) to solve various problems. The player himself cannot directly perform actions in the world, but interacts with the fairy-tale characters to have them perform various tasks, and to get information about the world and the problems to solve. Hence the role of spoken dialogue as the primary means of control is obvious and natural to the player. Naturally, this means that robust spoken language understanding becomes a critical component. To this end, the paper describes a semantic representation formalism and an accompanying parsing algorithm which works off the output of the speech recogniser's statistical language model. The evaluation shows that the parser is robust in the sense of considerably improving on the noisy output of the speech recogniser.

    Multi-slot semantics for natural-language call routing systems2007In: Proceedings of Bridging the Gap: Academic and Industrial Research in Dialog Technology, 2007, p. 68-75Conference paper (Refereed)
    Abstract [en]

    Statistical classification techniques for natural-language call routing systems have matured to the point where it is possible to distinguish between several hundreds of semantic categories with an accuracy that is sufficient for commercial deployments. For category sets of this size, the problem of maintaining consistency among manually tagged utterances becomes limiting, as lack of consistency in the training data will degrade performance of the classifier. It is thus essential that the set of categories be structured in a way that alleviates this problem, and enables consistency to be preserved as the domain keeps changing. In this paper, we describe our experiences of using a two-level multi-slot semantics as a way of meeting this problem. Furthermore, we explore the ramifications of the approach with respect to classification, evaluation and dialogue design for call routing systems.

    Negotiative Spoken-Dialogue Interfaces to Databases2003In: Proceedings of Diabruck, Wallerfangen, Germany, 2003Conference paper (Refereed)
    Abstract [en]

    The aim of this paper is to develop a principled and empirically motivated approach to robust, negotiative spoken dialogue with databases. Robustness is achieved by limiting the set of representable utterance types. Still, the vast majority of utterances that occur in practice can be handled.

    Robust parsing and spoken negotiative dialogue with databases2008In: Natural Language Engineering, ISSN 1351-3249, E-ISSN 1469-8110, Vol. 14, no 3, p. 289-312Article in journal (Refereed)
    Abstract [en]

    This paper presents a robust parsing algorithm and semantic formalism for the interpretation of utterances in spoken negotiative dialogue with databases. The algorithm works in two passes: a domain-specific pattern-matching phase and a domain-independent semantic analysis phase. Robustness is achieved by limiting the set of representable utterance types to an empirically motivated subclass which is more expressive than propositional slot–value lists, but much less expressive than first-order logic. Our evaluation shows that in actual practice the vast majority of utterances that occur can be handled, and that the parsing algorithm is highly efficient and accurate.

    Robust Parsing of Utterances in Negotiative Dialogue2003In: Proceedings 8th European Conference on Speech Communication and Technology (Eurospeech), Geneva, Switzerland, 2003Conference paper (Refereed)
    Abstract [en]

    This paper presents an algorithm for domain-dependent parsing of utterances in negotiative dialogue. To represent such utterances, the algorithm outputs semantic expressions that are more expressive than propositional slot-filler structures. It is very fast and robust, yet precise and capable of correctly combining information from different utterance fragments.

    Contextual reasoning in multimodal dialogue systems: two case studies2004In: Proceedings of The 8th Workshop on the Semantics and Pragmatics of Dialogue Catalogue'04, Barcelona, 2004, p. 19-21Conference paper (Refereed)
    Abstract [en]

    This paper describes an approach to contextual reasoning for interpretation ofspoken multimodal dialogue. The approach is based on combining recencybased search for antecedents with an object-oriented domain representation insuch a way that the search is highly constrained by the type information of theantecedents. By furthermore representingcandidate antecedents from the dialoguehistory and visual context in a uniformway, a single machinery (based on -reduction in lambda calculus) can be usedfor resolving many kinds of underspecified utterances. The approach has beenimplemented in two highly different domains.

    Deliverable 1.2: Initial version of requirements specification for CDD2013Report (Other academic)
    Abstract [en]

    The CaaS project will elaborate the Capability Driven Development (CDD) approach that will allow digital enterprises to exploit the notion of 'capability' as a means of both designing for services and with services. This deliverable defines an initial set of requirements for CDD. These requirements are provided by the industrial partners through exploration of their use cases. The goal of this deliverable is to identify potential benefits that the CaaS approach could bring to the use cases as well the features to be included the CDD methodology. The requirements are elicited from the use case partners during semi-structured interviews. They are documented in a form of goal models, actor models and concept models for each partner separately. Information documented in these models is used to define envisioned capabilities to be design and delivered during the project as well as to establish the scope of each use case. The use case scope definition focuses on use case goals, causes of capability delivery variability, capability delivery context, functions to be provided in the use case as well as potential capability delivery adjustments. The use case specific models are combined together to obtain a preliminary set of general requirements for CDD. These requirements show CDD goals, types of stakeholders, types of context and types of adjustments. The deliverable ends with concluding remarks about the partners’ expectations for CDD. The requirements for the use cases described in this deliverable will be further elaborated in the final requirements document deliverable D1.4 and will be iteratively refined during the use case elaboration performed in work packages WP2, WP3 and WP4.

    Abstract [en]

    Organizations operate in increasingly dynamic and diverse environments. This leads to high variability within the organization, and the necessity to create context-aware information systems. As a part of these systems, context and business process metrics need to be monitored and acted upon. Capability Driven Development (CDD) addresses these challenges and integrates organizational development with IS (Information System) development. This paper integrates results from an industry survey and three industrial cases to define the key methodology goals for CDD.

    Are beryllium-containing biphenyl derivatives efficient anion sponges?2018In: Journal of Molecular Modeling, ISSN 1610-2940, E-ISSN 0948-5023, Vol. 24, no 1, article id 16Article in journal (Refereed)
    Abstract [en]

    The structures and stabilities of 2,2'-diBeX-1,1'-biphenyl (X = H, F, Cl, CN) derivatives and their affinities for F-, Cl-, and CN- were theoretically investigated using a B3LYP/6-311 + G(3df, 2p)//B3LYP/6-31 + G(d,p) model. The results obtained show that the 2,2'-diBeX-1,1'-biphenyl derivatives (X = H, F, Cl, CN) exhibit very high F-, Cl-, and CN- affinities, albeit lower than those reported before for their 1,8-diBeX-naphthalene analogs, in spite of the fact that the biphenyl derivatives are more flexible than their naphthalene counterparts. Nevertheless, some of the biphenyl derivatives investigated are predicted to have anion affinities larger than those measured for SbF5, which is considered one of the strongest anion capturers. Therefore, although weaker than their naphthalene analogs, the 2,2'-diBeX-1,1'-biphenyl derivatives can still be considered powerful anion sponges. This study supports the idea that compounds containing -BeX groups in chelating positions behave as anion sponges due to the electron-deficient nature and consequently high intrinsic Lewis acidity of these groups.

    Barn med funktionsnedsättningar har ofta lyfts fram som vinnare när man talat om användning av IKT i skolan. Förväntningarna på vad IKT skulle medföra för elever i behov av särskilt stöd har varti stora både bland föräldrar och lärare. När den nya tekniken inroducerades antogs den kunna lösa många problem för barn med svårigheter av olika slag och därigenom bidra till att de bättre skulle kunna tillgodogöra sig undervisningen i skolan. Idag vet vi att det krävs mer än bara teknik.

    Dagens skola har svårt att skapa miljöer där barn med olika förutsättningar kan mötas i gemenskap och på lika villkor. Trenden visar att elever med funktionsnedsättningar allt oftare särskiljs istället för att inkluderas i en skola för alla. Tekniken finns men svårigheten ligger i att implementera den i barns och ungas daliga liv.

    The application of Item Response Theory on a teaching strategy profile questionnaire2010In: BMC Medical Education, ISSN 1472-6920, E-ISSN 1472-6920, Vol. 10, no 14Article in journal (Refereed)
    Abstract [en]

    Background

    In medical education research, various questionnaires are often used to study possible relationships between strategies and approaches to teaching and learning and the outcome of these. However, judging the applicability of such questionnaires or the interpretation of the results is not trivial.

    Methods

    As a way to develop teacher thinking, teaching strategy profiles were calculated for teachers in a research intensive department at Karolinska Institutet. This study compares the sum score, that was inherent in the questionnaire used, with an Item Response Theory (IRT) approach. Three teaching dimensions were investigated and the intended sum scores were investigated by IRT analysis.

    Results

    Agreements as well as important differences were found. The use of the sum score seemed to agree reasonably with an IRT approach for two of the dimensions, while the third dimension could not be identified neither by a the sum score, nor by an IRT approach, as the items included showed conflicting messages.

    Conclusions

    This study emphasizes the possibilities to gain better insight and more relevant interpretation of a questionnaire by use of IRT. A sum score approach should not be taken for granted. Its use has to be thoroughly evaluated.

    Microsimulation Models for Disaster Policy Making2005Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Two executable simulation models for answering policy questions were designed and implemented. The first for a flood management case, and the second for a disease transmission case that is currently underway. The flood simulation model differs from earlier natural disaster simulation models in several respects. It represents explicitly the geographical location and the economic strength of each household. It is also equipped with a graphical user interface, making it possible to design policies interactively, and to test their outcomes. If policy options are compared, the simulation results can automatically be transformed into decision trees. The flood simulation model shows that a micro-level representation makes it possible to investigate the distributional effects of policy changes. Novel features of the disease transmission model include the use of (anonymized) data representing nine million individuals, the inclusion of important parts of the contact patterns, and the explicit representation of places. The disease transmission model shows that the incorporation of social structure allows for a more realistic representation of disease spread than do models that assume homogenous mixing. Using this model, it is possible to conduct experiments of significant policy relevance, such as investigating the initial growth of an epidemic on a real-world network. Together, the two cases demonstrate the usefulness of a spatially explicit micro-level representation for policy simulation models in the area of disaster management.

    Spatial and Dynamic Modelling of Flood Management Policies in the Upper Tisza2003Report (Refereed)
    Abstract [en]

    Flood management policy has been the subject of an international joint research

    project with the Upper Tisza in Hungary as its pilot study area. Design specications

    for a geographically explicit simulation model are presented. Potential flood

    management policies, based on surveys and interviews with stakeholders, are presented.

    Some experiments on an executable prototype of the simulation model are

    also reported on, where the consequences of flood management policies are investigated.

    Focus has been on nancial policy measures, mainly insurance. Besides

    more traditional evaluation of policy scenarios, the model incorporates adaptive

    optimisation functionality. The report incorporates three contributions:

    1. the insurance policy issue in Hungary is framed in the broader context of flood

    management

    2. the structuring of a flood risk policy model, capable of simulating flood failures

    and estimating the economic consequences

    3. reports from policy experiments performed on the implemented prototype

    flood risk policy model

    Micro-simulation of a smallpox outbreak using official register data2010In: Euro surveillance, ISSN 1025-496X, Vol. 15, no 35, p. 17-24Article in journal (Refereed)
    Abstract [en]

    To explore the efficacy of four vaccine-based policy strategies (ring vaccination, targeted vaccination, mass vaccination, and pre-vaccination of healthcare personnel combined with ring vaccination) for controlling smallpox outbreaks in Sweden, disease transmission on a spatially explicit social network was simulated. The mixing network was formed from high-coverage official register data of the entire Swedish population, building on the Swedish Total Population Register, the Swedish Employment Register, and the Geographic Database of Sweden. The largest reduction measured in the number of infections was achieved when combining ring vaccination with a pre-vaccination of healthcare personnel. In terms of per dose effectiveness, ring vaccination was by far the most effective strategy. The results can to some extent be adapted to other diseases and environments, including other countries, and the methods used can be analysed in their own right.

    Multi-criteria decision-making of policy strategies with public-private re-insurance systems.2004In: Risk, Decision, and Policy, ISSN 1357-5309, E-ISSN 1466-4534, Vol. 9, no 1, p. 23-45Article in journal (Refereed)
    Abstract [en]

    This article describes an integrated flood catastrophe model as well as some results of a case study made in the Upper Tisza region in north-eastern Hungary: the Palad-Csecsei basin. The background data was provided through the Hungarian Academy of Sciences and complemented by interviews with different stakeholders in the region. Based on these data, for which a large degree of uncertainty is prevailing, we demonstrate how an implementation of a simulation and decision analytical model can provide insights into the effects of imposing different policy options for a flood risk management program in the region. We focus herein primarily on general options for designing a public-private insurance and reinsurance system for Hungary. Obviously, this is a multi-criteria and multi-stakeholder problem and cannot be solved using standard approaches. It should, however, be emphasised that the main purpose of this article is not to provide any definite recommendations, but rather to explore a set of policy packages that could gain a consensus among the stakeholders.

    Den ljusnande framtid är vård: delresultat från LEV-projektet2010Report (Other academic)
    Abstract [sv]

    År 2050 väntas andelen äldre i befolkningen öka från dagens 17 procent till 25 procent. Befolkningen åldras, hälsan förbättras och livslängden ökar. Det är en positiv utveckling som samhället måste anpassas till.

    Därför har en arbetsgrupp inom Socialdepartementet med en unik modell simulerat hur 300 000 individer åldras fram till 2050 och hur det väntas påverka hälsa, sjuklighet och dödlighet samt det framtida behovet av vård och omsorg. Simuleringarna visar att det är möjligt att kombinera åtgärder för att möta den åldrande befolkningens ökande behov av vård och omsorg om 10-15 år. Men det krävs ett målmedvetet arbete med att

    • förbättra hälsa och funktionsförmåga,
    • öka tillgängligheten,
    • få en effektiv vård och omsorg som tillämpar dagens kunskap och tänker nytt
    • forska och utveckla.

    Applying the Consumat Model to Flood Management Policies2003In: Agent-based simulation, 2003Conference paper (Refereed)
    Abstract [en]

    The number and severity of weather related catastrophes is

    increasing. Economic losses from these catastrophes are

    escalating, mainly as a result of concentration of assets and

    population in high-risk areas. How to deal with these

    economic liabilities in a fair way at the level of the individual

    property owners is the focus of our research.

    As a case study we choose the Tisza, a river in Hungary that

    flows through one of the poorest agricultural regions of

    Europe that frequently floods. The use of a simulation model

    for evaluating alternative flood management policies is a

    natural choice, since it is impossible to predict the time,

    location and magnitude of a flood; historical data is of limited

    use when looking at the outcome of future policies. The

    behaviour of the river and the financial consequences are

    simulated on a year-by-year basis.

    Here we have extended the simulation model by using the

    Consumat approach to model the individual property owners.

    We compare the results with respect to wealth distribution in

    the case of Consumat agents and simple (non-Consumat)

    agents. In the Consumat case, the results show that system is

    more dynamic and more realistic.

    Abstract [en]

    Online review Web sites have enabled new interactions between companies and their customers. In this articlewe draw on interviews with users, reviewers, and establishments to explore how local review Web sitescan change interactions around local places. ReviewWeb sites such as Yelp and Tripadvisor allow customersto “previsit” establishments and areas of a city before an actual visit. The collection of a large numbers ofuser-generated reviews has also created a new genre of writing, with reviewers gaining considerable pleasurefrom passing on word of mouth and influencing others’ choices. Reviews also offer a new channel ofcommunication between establishments, customers, and competitors. We discuss how review Web sites canbe designed to cater for a broader range of interactions around reviews beyond a focus on recommendations

    Ephemeral Photowork: Understanding the Mobile Social Photography Ecosystem2016In: Proceedings of the Tenth International AAAI Conference onWeb and Social Media (ICWSM 2016), AAAI Press, 2016, p. 551-554Conference paper (Refereed)
    Abstract [en]

    For many years, researchers have explored digital support for photographs and various methods of interaction around those photos. Services like Instagram, Facebook, and Flickr have demonstrated the value of online photographs in social media. Yet we know relatively little about these new practices of mobile social photography and in-situ sharing. Drawing on screen and audio recordings of mobile photo app use, this paper documents the ephemeral practices of social photography with mobile devices. We uncover how photo use on mobile devices is centered around social interactions both through online services, but also face-to-face around the devices themselves. We argue for a new role for the mobile photograph, supporting networks of communication through instantaneous interactions, complemented with rich, in person discussions of captured images with family and friends; photography not for careful selection and archive, but as quick social play and talk. The paper concludes by discussing the design possibilities of ephemeral communication.

    Enjoying Machines2015Book (Other academic)
    Abstract [en]

    The dominant feature of modern technology is not how productive it makes us, or how it has revolutionized the workplace, but how enjoyable it is. We take pleasure in our devices, from smartphones to personal computers to televisions. Whole classes of leisure activities rely on technology. How has technology become such an integral part of enjoyment? In this book, Barry Brown and Oskar Juhlin examine the relationship between pleasure and technology, investigating what pleasure and leisure are, how they have come to depend on the many forms of technology, and how we might design technology to support enjoyment. They do this by studying the experience of enjoyment, documenting such activities as computer gameplay, deer hunting, tourism, and television watching. They describe technologies that support these activities, including prototype systems that they themselves developed.

    Brown and Juhlin argue that pleasure is fundamentally social in nature. We learn how to enjoy ourselves from others, mastering it as a set of skills. Drawing on their own ethnographic studies and on research from economics, psychology, and philosophy, Brown and Juhlin argue that enjoyment is a key concept in understanding the social world. They propose a framework for the study of enjoyment: the empirical program of enjoyment.
