    General and reference Metrics; Applied com- puting Business process modeling; Software and its engineering System modeling languages; Computing methodologies Model veri cation and validation;The Case Management Modeling and Notation (CMMN) speci cation, published by the Object Management Group (OMG) in 2014, describes a declarative style for modeling business processes. The declarative nature of CMMN is in- tended to supplement the procedural style of the Business Process Modeling and Notation (BPMN). Although multi- ple metrics have been developed and veri ed for BPMN, the authors are not aware of any metrics developed for CMMN. Being a relative new process speci cation the understanding of complexity metrics for CMMN ought to be bene cial for practitioners and researchers by providing a way to compare case management models. This study provides a formal description of CMMN and three metrics are de ned, namely size, length, and complex- ity. The metrics are theoretically validated using the formal framework for software measurements de ned by Briand et al. and the complexity metric is further validated using Weyuker's properties for software complexity measures.College of Engineering, Science and Technolog

    D.2.2 [Design Tools and Techniques]; D.2.3 [Coding Tools and Techniques]: Standards; D.10 [Design]: Rep- resentationIn 2014, the Object Management Group (OMG) published the Case Management Modeling and Notation (CMMN) ver- sion 1.0 speci cation, which is a new process modeling spec- i cation to complement its Business Process Modeling and Notation (BPMN) speci cation. The declarative nature of CMMN is intended to supplement the procedural perspec- tive of BPMN. CMMN takes a data-centric view to process modeling based on business artifacts to provide exibility for knowledge workers, while retaining the advantages of busi- ness process management (BPM) systems. As far as the researchers are aware, this research is among the rst contributions to the understanding of CMMN's method complexity in the context of other process modeling nota- tions. We used the meta-model-based method complexity approach introduced by Rossi and Brinkkemper to evalu- ate the method complexity of CMMN. The results were compared with other popular process methods, including BPMN, Uni ed Modeling Language (UML) Activity dia- grams, and Event-driven Process Charts (EPC), all of which have undergone similar evaluations by other researchers. The initial results indicated that CMMN 1.0 compares favorably with BPMN 1.2.College of Engineering, Science and Technolog

    'Language has a heart': linguistic markers of evaluation in selected TRC testimonies

    This paper explores how two testifiers at the Human Rights Violation hearings of South Africa's Truth and Reconciliation Commission in 1996 used selected markers of evaluation (shifts in tense, the inclusion of direct speech and code-switching) to express evaluative meanings and position themselves, the police and their audiences in relation to their narratives. Both testifiers are mothers of young activists who were pursued, detained and tortured by police in the 1980s. The paper argues that it is through the subtle though significant linguistic choices the women make that their perspective is construed and their 'narrative truth' realized

    The relationship between interpersonal needs and conflict-handling styles. Various factors such as behavioural tendencies, interpersonal preferences and personality characteristics play a role in conflict-handling styles. The aim of this investigation was to determine the relationship between interpersonal needs and conflict-handling styles

    The Cash Cows, Dogs, Stars and Problem Children of the South African Agricultural Sector

    This paper investigates the development path of different agricultural sectors over the past 10 years in order to identify those subsectors that can contribute significantly towards reducing poverty and increasing national & household food security. The Boston Consulting Group (BCG) matrix was used to analyse growth patterns for different agricultural subsectors and classify them as cash cows, dogs, stars and question marks. The results show that the real average growth for the agricultural sector over the last ten years was 5.64 %. Of the 44 agricultural subsectors, 9 subsectors show a negative growth. The BCG matrix indicates one cash cow industry (sugar cane), eight dogs’(sisal, cotton, tobacco, tea, chicory, mohair, fry peas, dried fruit), fourteen stars (fowls slaughtered, maize, cattle & calves slaughtered, milk, vegetables, deciduous and other fruit, eggs, citrus fruit, wheat, potatoes, hay, viticulture, sheep and goats slaughtered, pigs slaughtered) and twenty one question marks. Institutional intervention by the public-private sectors are therefore necessary to unlock the potential of the problem children, maintain the momentum of the stars, extent the life of the cash cow and decide on the future of the dogs

    Effective recruitment strategies in primary care research: A systematic review

    No full text
    Background: Patient recruitment in primary care research is often a protracted and frustrating process, affecting project timeframes, budget and the dissemination of research findings. Yet, clear guidance on patient recruitment strategies in primary care research is limited. This paper addresses this issue through a systematic review. Method: Articles were sourced from five academic databases – AustHealth, CINAHL, the Cochrane Methodology Group, EMBASE and PubMed/Medline; grey literature was also sourced from an academic library and the Primary Healthcare Research & Information Service (PHCRIS) website. Two reviewers independently screened the articles using the following criteria: (1) published in English, (2) reported empirical research, (3) focused on interventions designed to increase patient recruitment in primary care settings, and (4) reported patient recruitment in primary care settings.Results: Sixty-six articles met the inclusion criteria. Of these, 23 specifically focused on recruitment strategies and included randomised trials (n = 7), systematic reviews (n = 8) and qualitative studies (n = 8). Of the remaining articles, 30 evaluated recruitment strategies, while 13 addressed the value of recruitment strategies using descriptive statistics and/or qualitative data. Among the 66 articles, primary care chiefly included general practice (n = 30); nursing and allied health services, multiple settings, as well as other community settings (n = 30); and pharmacy (n = 6). Effective recruitment strategies included the involvement of a discipline champion, simple patient eligibility criteria, patient incentives and organisational strategies that reduce practitioner workload. Conclusion: The most effective recruitment in primary care research requires practitioner involvement. The active participation of primary care practitioners in both the design and conduct of research helps to identify strategies that are congruent with the context in which patient care is delivered. This is reported to be the optimal recruitment strategy
