Strategic Implementation

Background: Despite Government investment, disparity in access to clinical trials continue between metropolitan and regional & rural sectors (RRR) in Australia and around the world. To improve trial access closer to home for RRR communities and rare cancer patients even in metro settings, the Australasian Teletrial Model (ATM) was developed by Clinical Oncology Society of Australia and implemented in four states. Aim of this paper is to describe the steps and processes involved in the development and implementation of ATM guided by implementation science frameworks. Method: Two implementation science frameworks namely iPARIHS and Strategic Implementation Framework were chosen to guide the project. Details of steps and processes were extracted from COSA final report. Results: ATM met the criteria for worthy innovation. For the development and implementation of the ATM, stakeholders were at national, statewide and clinical levels. A co-design with end-users and inclusion of key stakeholders in steering committees and advisory groups made the implementation smoother. Clinician levers including advocacy were useful to overcome system barriers. During the project, more patients, and clinicians at RRR participated in trials, more primary sites collaborated with RRR sites and more RRR sites gained trial capabilities. Conclusion: Pilot project achieved its objectives including improved access to patients locally, creation of linkages between metro and RRR sites and enhanced capabilities of and access to RRR sites. Implementation science frameworks were useful for identifying the necessary steps and processes at the outset. Ownership by governments and creation of streamlined regulatory systems would enable broader adoption.

Open Case

AbstractMotivated by several conjectures due to Nikoghosyan, in a recent article due to Li et al., the aim was to characterize all possible graphs H such that every 1-tough H-free graph is hamiltonian. The almost complete answer was given there by the conclusion that every proper induced subgraph H of $$K_1\cup P_4$$ K 1 ∪ P 4 can act as a forbidden subgraph to ensure that every 1-tough H-free graph is hamiltonian, and that there is no other forbidden subgraph with this property, except possibly for the graph $$K_1\cup P_4$$ K 1 ∪ P 4 itself. The hamiltonicity of 1-tough $$K_1\cup P_4$$ K 1 ∪ P 4 -free graphs, as conjectured by Nikoghosyan, was left there as an open case. In this paper, we consider the stronger property of pancyclicity under the same condition. We find that the results are completely analogous to the hamiltonian case: every graph H such that any 1-tough H-free graph is hamiltonian also ensures that every 1-tough H-free graph is pancyclic, except for a few specific classes of graphs. Moreover, there is no other forbidden subgraph having this property. With respect to the open case for hamiltonicity of 1-tough $$K_1\cup P_4$$ K 1 ∪ P 4 -free graphs we give infinite families of graphs that are not pancyclic.

Work Done

Abstract The Turán number ex(n, H) of a graph H is the maximal number of edges in an H-free graph on n vertices. In 1983, Chung and Erdős asked which graphs H with e edges minimise ex(n, H). They resolved this question asymptotically for most of the range of e and asked to complete the picture. In this paper, we answer their question by resolving all remaining cases. Our result translates directly to the setting of universality, a well-studied notion of finding graphs which contain every graph belonging to a certain family. In this setting, we extend previous work done by Babai, Chung, Erdős, Graham and Spencer, and by Alon and Asodi.

Abstract This paper presents a strategic approach for implementing a Smart Pedestrian Network (SPN) navigation System that is geared towards promoting sustainable mobility. The SPN system is being designed to reach multiple market segments by providing information on suitable walking routes aiming to satisfy potential users’ needs, but also multiple stakeholder demands. The paper presents the main objectives of the SPN system as well as its system structure, application features, functions, and relevant data sources. The proposed strategic implementation framework deems necessary for scaling up so that the SPN system is successfully implemented in a variety of urban conditions. The framework emphasizes the element of adaptability, so that SPN can be adjusted where and when necessary, to deal with a variety of contexts and specific sustainable mobility issues, depending on the particular municipality conditions. The proposed framework combines elements of both the waterfall and agile software development methods, as well as, aspects of Open Innovation, Customer Involvement and Co-Creation taking a multiple stakeholder approach.
