    Our thesis is that the analysis of unstructured data supports software understanding and evolution analysis, and complements the data mined from structured sources. To this aim, we implemented the necessary toolset and investigated methods for exploring, exposing, and exploiting unstructured data.To validate our thesis, we focused on development email data. We found two main challenges in using it to support program comprehension and software development: The disconnection between emails and code artifacts and the noisy and mixed-language nature of email content. We tackle these challenges proposing novel approaches. First, we devise lightweight techniques for linking email data to code artifacts. We use these techniques for creating a tool to support program comprehension with email data, and to create a new set of email based metrics to improve existing defect prediction approaches. Subsequently, we devise techniques for giving a structure to the content of email and we use this structure to conduct novel software analyses to support program comprehension. In this dissertation we show that unstructured data, in the form of development emails, is a valuable addition to structured data and, if correctly mined, can be used successfully to support software engineering activities

    BACKGROUND: In the past decade in activities aiming at return-to-work (RTW), there has been a growing awareness to change the focus from sickness and work disability to recovery and work ability. To date, this process in occupational health care (OHC) has mainly been directed towards employees. However, within the working population there are two vulnerable groups: temporary agency workers and unemployed workers, since they have no workplace/employer to return to, when sick-listed. For this group there is a need for tailored RTW strategies and interventions. Therefore, this paper aims to describe the structured and stepwise process of development, implementation and evaluation of a theory- and practise-based participatory RTW program for temporary agency workers and unemployed workers, sick-listed due to musculoskeletal disorders (MSD). This program is based on the already developed and cost-effective RTW program for employees, sick-listed due to low back pain. METHODS: The Intervention Mapping (IM) protocol was used to develop a tailor-made RTW program for temporary agency workers and unemployed workers, sick-listed due to MSD. The Attitude-Social influence-self-Efficacy (ASE) model was used as a theoretical framework for determinants of behaviour regarding RTW of the sick-listed worker and development of the intervention. To ensure participation and facilitate successful adoption and implementation, important stakeholders were involved in all steps of program development and implementation. Results of semi-structured interviews and 'fine-tuning' meetings were used to design the final participatory RTW program. RESULTS: A structured stepwise RTW program was developed, aimed at making a consensus-based RTW implementation plan. The new program starts with identifying obstacles for RTW, followed by a brainstorm session in which the sick-listed worker and the labour expert of the Social Security Agency (SSA) formulate solutions/possibilities for suitable (therapeutic) work. This process is guided by an independent RTW coordinator to achieve consensus. Based on the resulting RTW implementation plan, to create an actual RTW perspective, a vocational rehabilitation agency is assigned to find a matching (therapeutic) workplace. The cost-effectiveness of this participatory RTW program will be evaluated in a randomised controlled trial. CONCLUSION: IM is a promising tool for the development of tailor-made OHC interventions for the vulnerable working populatio

    Bodil Furnes, Elin DysvikUniversity of Stavanger, Faculty of Social Sciences, Department of Health Studies, Stavanger, NorwayObjective: The basic aim of this paper is to suggest a flexible and individualized writing program as a tool for use during the grief process of bereaved adults.Methods: An open, qualitative approach following distinct steps was taken to gain a broad perspective on the grief and writing processes, as a platform for the writing program.Results: Following several systematic methodological steps, we arrived at suggestions for the initiation of a writing program and its structure and substance, with appropriate guidelines.Discussion: We believe that open and expressive writing, including free writing and focused writing, may have beneficial effects on a person experiencing grief. These writing forms may be undertaken and systematized through a writing program, with participation in a grief writing group and with diary writing, to achieve optimal results.Conclusion: A structured writing program might be helpful in promoting thought activities and as a tool to increase the coherence and understanding of individuals in the grief process. Our suggested program may also be a valuable guide to future program development and research.Keywords: bereavement, grief process, writing proces

    Video Self-reflection and Coach Development in New Zealand

    Drawing on data from semi-structured interviews with New Zealand coaches (N = 6), this study examined how video self-reflection (VSR) was perceived as a tool for learning within ‘on-going’ coach development. This study also looked to determine the potential barriers experienced by coaches before engaging in VSR. Each participant was a performance coach (as identified by the NZ coach development framework (CDF)) with 5+ years coaching experience and had recently (in the previous 12 months) participated in a coach development program that aligned with Sport NZ’s CDF. Five main themes emerged from the data; coaches had a positive perception of the benefits of VSR, a desire to engage in VSR but did not prioritise the time, logistical concerns, a fear of self-confrontation and evidence of knowledge for ‘modern’ coaching development. Findings indicated that coaches valued VSR as a tool for learning; however, the lack of exposure and experience in the process meant coaches did not value the practise enough to dedicate specific time towards it. This study provides an evidence-base that can be used to support National Governing Bodies coach development frameworks, and the modification of content to encourage the use of VSR as a tool for learning

    Informing implementation of quality improvement in Australian primary care

    Background: Quality Improvement (QI) initiatives in primary care are effective at improving uptake of evidence based guidelines, but are difficult to implement and sustain. In Australia meso-level health organisations such as Primary health care Organisations (PHCO) offer new opportunities to implement area-wide QI programs. This study sought to identify enablers and barriers to implementation of an existing Australian QI program and to identify strategic directions that PHCOs can use in the ongoing development of QI in this environment. Methods: Semi-structured telephone interviews were conducted with 15 purposively selected program staff and participants from the Australian Primary Care Collaborative (APCC) QI program. Interviewees included seven people involved in design, administration and implementation of the APCC program and eight primary care providers (seven General Practitioners (GPs) and one practice nurse) who had participated in the program from 2004 to 2014. Interviewees were asked to describe their experience of the program and reflect on what enabled or impeded its implementation. Interviews were recorded, transcribed and iteratively analysed, with early analysis informing subsequent interviews. Identified themes and their implications were reviewed by a GP expert reference group. Results: Implementation enablers and barriers were grouped into five thematic areas: (1) leadership, particularly the identification and utilisation of change champions; (2) organisational culture that supports quality improvement; (3) funding incentives that support a culture of quality and innovation; (4) access to and use of accurate data; and 5) design and utilisation of clinical systems that enable and support these issues. In all of these areas, the active involvement of an overarching external support organisation was considered a key ingredient to successful implementation. Conclusion: There are substantial opportunities for PHCOs to play a pivotal role in QI implementation in Australia and internationally. In developing QI programs and policies, such organisations ought to invest their efforts in: (1) identifying and mentoring local leaders; (2) fostering QI culture via development of local peer networks; (3) developing and advocating for alternative funding models to support and incentivise these activities; (4) investing in data and audit tool infrastructure; and (5) facilitation of systems implementation within primary care practices

    The most commonly used systems specification and design techniques in commercial computing are described and compared; Information Engineering as proposed by James Martin, A Framework for Information Definition-Muitiview proposed by Wood-Harper et al, Real-world Modeling as described by Jackson, Structured Analysis and Design as In Demarco, Yourdon and Constantine and Output-Oriented Structured Requirement Definition proposed by Orr. In addition, system prototyping is discussed, including the role of prototyping in large software development projects and as a tool for the design of human-computer interfaces. Other areas described and discussed include decision support systems (DSS) and knowledge based management support systems. The context is in the design and development approaches for DSS, prototyping for DSS, expert system for DSS and the integration of DSS and information system. The design and development of human-computer interface is also discussed in relation to user Interface complexity and adaptive interfaces. Further, the important issue of user involvement and support within the development process Is discussed. Thus, weaknesses of current approaches to the system development process are identified and a new model for the development of information system is proposed. In proposing the model, data and functional analysis structured method and methodology for decision support systems (DSS) development is presented including guidelines for the development of knowledge based DSS. The new proposed model is put to test in the design, development and implementation of large integrated commercial systems including DSS. Results and discussion on the use of the model is reported with special consideration to the users' and developers' view of the model. Finally the objectives of this research program are examined in relation to what has been achieved during this program of research. The prospect of using the model for the development of information systems are concluded with references to current and future goals

    FIST and the Analytical Hierarchy Process: Comparative Modeling

    Get PDF
    FIST is an emerging and unproven rapid acquisition model that stands for Fast, Inexpensive, Simple, and Tiny. The purpose of this research is to develop an Analytical Hierarchy Process (AHP) model based on the FIST concepts, to be applied as a comparative tool against the FIST model. The results indicate that the FIST model is reproducible with the AHP theory and that there are certain program characteristics that denote if a program would benefit from being developed by FIST. However, there are distinct weaknesses to the model that signify not all programs would succeed if FIST was employed during development. Eleven additional FIST activities are recommended for inclusion in the model with key activities comprising of an ambidextrous structured organization, better requirements gathering techniques, and utilizing incremental development
