    Patients' complaints regarding healthcare encounters and communication2018In: Nursing Open, E-ISSN 2054-1058, Vol. 5, no 2, p. 224-232Article in journal (Refereed)
    Abstract [en]

    Aim: To explore patient-reported complaints regarding communication and healthcare encounters and how these were responded to by healthcare professionals. Design: A retrospective and descriptive design was used in a County Council in northern part of Sweden. Both quantitative and qualitative methods were used. Methods: The content of 587 patient-reported complaints was included in the study. Descriptive statistical analysis and a deductive content analysis were used to investigate the content in the patient-reported complaints. Results: The results show that patients' dissatisfaction with encounters and communication concerned all departments in the healthcare organization. Patients were most dissatisfied when they were not met in a professional manner. There were differences between genders, where women reported more complaints regarding their dissatisfaction with encounters and communication compared with men. Many of the answers on the patient-reported complaints lack a personal apology and some of the patients failed to receive an answer to their complaints.

    Developing Inclusive Innovation Processes and Co-Evolutionary University-Society Approaches in Bolivia2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This study is part of a worldwide debate on inclusive innovation systems in developing

    countries and particularly on the co-evolutionary processes taking place, seen from the

    perspective of a public university. The increasing literature that discusses how innovation

    systems and development can foster more inclusive and sustainable societies has

    inspired this thesis work. Thus, the main problem handled in the research concerns the

    question how socially sensitive research practices and policies at a public university in

    Bolivia can be stimulated within emerging innovation system dynamics. In that vein,

    empirical knowledge is developed at the Universidad Mayor de San SimoÅLn (UMSS),

    Cochabamba as a contribution to experience-based learning in the field. Analysis are

    nourished by a dialogue with the work of prominent Latin American scholars and

    practitioners around the idea of a developmental university and the democratization

    of knowledge. The reader will be able to recognize a recursive transit between theory

    and practice, where a number of relevant concepts are contextualized and connected

    in order to enable keys of critical interpretation and paths of practices amplification

    for social inclusion purposes established. The study shows how, based on a previous

    experience, new competences and capacities for the Technology Transfer Unit (UTT)

    at UMSS were produced, in this case transforming itself into a University Innovation

    Centre. Main lessons gained in that experience came from two pilot cluster development

    (food and leather sectors) and a multidisciplinary researchers network (UMSS

    Innovation Team) where insights found can improve future collaborative relations between

    university and society for inclusive innovation processes within the Bolivian

    context.

    Using Tag based Semantic Annotation to Empower Client and REST Service Interaction2018In: Proceedings of the 3rd International Conference on Complexity, Future Information Systems and Risk - Volume 1: COMPLEXIS, SciTePress, 2018, p. 64-71Conference paper (Refereed)
    Abstract [en]

    The utilization of Web services is becoming a human labor consuming work as the rapid growth of Web. The semantic annotated service description can support more automatic ways on tasks such as service discovery, invocation and composition. But the adoption of existed Semantic Web Services solutions is hindering by their overly complexity and high expertise demand. In this paper we propose a highly lightweight and non-intrusive method to enrich the REST Web service resources with semantic annotations to support a more autonomous Web service utilization and generic client service interaction. It is achieved by turning the service description into a semantic resource graph represented in RDF, with the added tag based semantic annotation and a small vocabulary. The method is implemented with the popular OpenAPI service description format, and illustrated by a simple use case example.

    Regression testing goals: View of practitioners and researchers2017In: 24th Asia-Pacific Software Engineering Conference Workshops (APSECW), IEEE, 2017, p. 25-32Conference paper (Refereed)
    Abstract [en]

    Context: Regression testing is a well-researched area. However, the majority regression testing techniques proposed by the researchers are not getting the attention of the practitioners. Communication gaps between industry and academia and disparity in the regression testing goals are the main reasons. Close collaboration can help in bridging the communication gaps and resolving the disparities.Objective: The study aims at exploring the views of academics and practitioners about the goals of regression testing. The purpose is to investigate the commonalities and differences in their viewpoints and defining some common goals for the success of regression testing.Method: We conducted a focus group study, with 7 testing experts from industry and academia. 4 testing practitioners from 2companies and 3 researchers from 2 universities participated in the study. We followed GQM approach, to elicit the regression testing goals, information needs, and measures.Results: 43 regression testing goals were identified by the participants, which were reduced to 10 on the basis of similarity among the identified goals. Later during the priority assignment process, 5 goals were discarded, because the priority assigned to these goals was very low. Participants identified 47 information needs/questions required to evaluate the success of regression testing with reference to goal G5 (confidence). Which were then reduced to10 on the basis of similarity. Finally, we identified measures to gauge those information needs/questions, which were corresponding to the goal (G5).Conclusions: We observed that participation level of practitioners and researchers during the elicitation of goals and questions was same. We found a certain level of agreement between the participants regarding the regression testing definitions and goals.But there was some level of disagreement regarding the priorities of the goals. We also identified the need to implement a regression testing evaluation framework in the participating companies.

    Experimental and numerical assessment of the work of fracture in injection-moulded low-density polyethylene2018In: Engineering Fracture Mechanics, ISSN 0013-7944, E-ISSN 1873-7315, ISSN 0013-7944, Vol. 192, p. 1-11Article in journal (Refereed)
    Abstract [en]

    The fracture mechanics properties of injection-moulded low-density polyethylene (LDPE) sheets were investigated both experimentally and numerically. The total work of fracture was determined experimentally, by means of fracture mechanics testing of sheets of injection-moulded LDPE with side cracks of different lengths. A multi-specimen method, proposed by Kim and Joe (1987), was employed. The total work of fracture was estimated to 13 kJ/m2. The experiments were simulated numerically using the finite element method. Crack growth was enabled by inclusion of a cohesive zone, and the constitutive response of this zone was governed by a traction-separation law. The local (or essential) work of fracture was estimated through numerical analyses, where the initiation of crack growth was simulated and the outcome was compared to the experimental results. The local (i.e. essential) work of fracture was estimated to 1.7 kJ/m2, which is consistent with previous experimental measurements for the material in question. The total work of fracture, retrieved from the present experiments, agreed well with the far field values of the J-integral in the numerical analyses. © 2018 The Authors

    Utilization of Broadband Connectivity in Rural and Urban-Underserved Areas:  The case of Selected Areas in Arusha-Tanzania2018In: International Journal of Computing and Digital Systems, ISSN 1446-8956, E-ISSN 1329-7147, no 2, p. 75-83Article in journal (Refereed)
    Abstract [en]

     Utilization is a key aspect in the management of any societal resource not only when it is scarce but in all cases to allow for optimum benefits to be accrued to everyone in the society. Internet bandwidth, which is a rare commodity especially in rural areas is hardly available where needed at the same cost and quality due to various reasons. Tanzania as a case study is among countries that have invested much in international, national and metro backbone networks, but still, there are areas without or with inadequate internet access services implying a significant utilization problem. In this paper, we present as a case study, the status of broadband connectivity in selected rural areas in Tanzania (Arusha) and the status is used to make recommendations for optimized utilization of installed capacity.
