    Get PDF
    Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness. A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense. Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice

    Efficient instance and hypothesis space revision in Meta-Interpretive Learning

    Inductive Logic Programming (ILP) is a form of Machine Learning. The goal of ILP is to induce hypotheses, as logic programs, that generalise training examples. ILP is characterised by a high expressivity, generalisation ability and interpretability. Meta-Interpretive Learning (MIL) is a state-of-the-art sub-field of ILP. However, current MIL approaches have limited efficiency: the sample and learning complexity respectively are polynomial and exponential in the number of clauses. My thesis is that improvements over the sample and learning complexity can be achieved in MIL through instance and hypothesis space revision. Specifically, we investigate 1) methods that revise the instance space, 2) methods that revise the hypothesis space and 3) methods that revise both the instance and the hypothesis spaces for achieving more efficient MIL. First, we introduce a method for building training sets with active learning in Bayesian MIL. Instances are selected maximising the entropy. We demonstrate this method can reduce the sample complexity and supports efficient learning of agent strategies. Second, we introduce a new method for revising the MIL hypothesis space with predicate invention. Our method generates predicates bottom-up from the background knowledge related to the training examples. We demonstrate this method is complete and can reduce the learning and sample complexity. Finally, we introduce a new MIL system called MIGO for learning optimal two-player game strategies. MIGO learns from playing: its training sets are built from the sequence of actions it chooses. Moreover, MIGO revises its hypothesis space with Dependent Learning: it first solves simpler tasks and can reuse any learned solution for solving more complex tasks. We demonstrate MIGO significantly outperforms both classical and deep reinforcement learning. The methods presented in this thesis open exciting perspectives for efficiently learning theories with MIL in a wide range of applications including robotics, modelling of agent strategies and game playing.Open Acces

    ADVANCING THE QUADRUPLE AIM IN MEDI-CAL MANAGED CARE: PROVIDER AND HEALTH PLAN LEADER PERSPECTIVES REGARDING THE INCLUSION OF PARAPROFESSIONALS ON CARE TEAMS FOR DEVELOPMENTAL SCREENING AND CARE COORDINATION

    Get PDF
    Problem Approximately 25% of Medi-Cal enrollees receive a developmental screening in the first three years of life, a rate below the 33% national benchmark (DHCS 2020). Medi-Cal providers cite limited time as a barrier to completing developmental screenings (First 5 LA 2017). Literature supports inclusion of unlicensed paraprofessionals on teams to increase developmental screening and service referral rates (Minkovitz 2003, Warmels 2017). An understanding of facilitators and barriers to adding paraprofessionals such as community health workers (CHWs) and care coordinators to teams can inform pediatric transformation initiatives. Research regarding workforce transformation strategies is pivotal as California advances a CHW Medi-Cal benefit in 2022 and prepares for a physician shortage (Chapman 2017, LAO 2021, Spetz 2017). Pediatric paraprofessionals could advance the “quadruple aim”- improving population health, enhancing patient experience, reducing per capita cost of health care, and improving clinician work life (Bodenheimer 2014). As the majority of Medi-Cal enrollees face health disparities, ensuring pediatric members with developmental concerns are routed to services could address the “quintuple aim,” which includes improving health equity (Nundy 2022).Methodology This mixed methods study analyzed 10 Medi-Cal providers’ and 10 Medi-Cal plan clinical leaders’ perceptions of facilitators and barriers impacting timely developmental screening and coordination to services and supports. The study then identified facilitators and barriers to shifting developmental screening and care coordination tasks to paraprofessionals. Results Medi-Cal provider and health plan informants were receptive to incorporating paraprofessionals on teams to perform select developmental screening and care coordination tasks. Facilitators included leaders committed to early identification and intervention (EII), a training and supervisory infrastructure, and software optimized for screenings and referrals. The major barrier was a perception of inadequate reimbursement. Few respondents perceived health plans as drivers of successful EII, suggesting an opportunity for California regulators to enforce screening and coordination requirements, fund pediatric workforce transformation, and route families to care coordination resources.Recommendations The research suggests major reimbursement needs to adequately support of developmental screening and care coordination tasks. Study findings can inform leaders pursuing pediatric workforce transformation initiatives in Medi-Cal. Additional qualitative research with paraprofessionals and families is warranted to refine workforce transformation approaches.Doctor of Public Healt

    Early Childhood Science Education: Research Trends in Learning and Teaching

    Get PDF
    This volume consists of a collection of articles that touch on very different research aspects within a broad scientific field known in recent years as Early Childhood Science Education. The field has gradually emerged from the interaction between three distinct scientific areas of theory and research: Early Childhood Education, Psychology, which is oriented towards the study of learning, and Science Education. At the center of the progress in this field are efforts to initiate children aged 4-8 years in the Physical and Biological Sciences. A wide range of research themes have developed around this main axis: children's mental representations of phenomena of the natural world and scientific concepts, the study of the implementation and effectiveness of specific teaching activities related to curricula or activities focusing on the specific characteristics of teaching processes such as reasoning, explanation, communication, interaction or argumentation, the issue of teachers' relevance to the teaching of science, the use of pecialized teaching materials, the emergence of the issue of scientific skills, the highly contemporary issue of the differentiation and inclusion of children in the world of science, important socio-scientific issues, the role of family-related factors etc. Within this context, this collective book aims to reflect contemporary research trends in the field of Early Childhood Science Education

    Understanding factors affecting the teaching of teamwork in Australian higher education business schools

    Get PDF
    Integrating teamwork into higher education (HE) curricula has been part of the employability skills agenda for decades. Whilst HE academics have published widely on a variety of strategies utilised to implement teamwork in their teaching, there is little evidence of the interrelated factors associated with teaching teamwork and the paradoxes of critical tension points arising from challenges encountered by educators in their efforts to integrate teamwork in their courses. This thesis explores the salient influences affecting the teaching and learning of teamwork in the Australian HE business school context. The outcomes are presented in a thesis by compilation, which includes the traditional structure of introduction, literature review, methodology, findings/discussion, and conclusion chapters, along with three published articles demonstrating original, primary research. A published global systematic literature review (SLR) identified that temporal, fiscal, psychological, and human resource transaction cost interactions for HE educators, students and institutions affected the uptake of HE teamwork. Interactions are predicated on the way in which educators derive benefits or costs from developing, coordinating, monitoring, participating in, interacting with, and evaluating HE teamwork. Transaction costs, for example, whether to engage with the employability agenda, or provide instruction in team skills, collaborative learning, curriculum design, and assessment of teamwork, represent the return on investment to educators when undertaking the teaching of teamwork. These findings are an original contribution to the HE teamwork literature as there is scant evidence of costs associated with affording or constraining HE teamwork. A second published SLR article was confined to a more rigorous review of the Australian HE teamwork literature. Numerous factors were identified as constraints to HE teamwork, with findings thematically indicating that Australian business discipline educators were mainly concerned with team formation and management, teaching and learning approaches to HE teamwork and challenges influencing teaching and learning practices, thus providing an original contribution to knowledge of the salient issues affecting the teaching and learning of teamwork in the Australian business school context. These findings were used to inform semi-structured interview questions for a case study of business educators from a range of disciplines across four public universities in Australia. Grounded in a social constructivist paradigm, and using the case study approach, findings from 30 qualitative interviews with Australian business educators identified that performative demands on HE educators resulted in a range of critical paradox tension points, highlighting the salient influences contributing to understanding educator factors affecting the teaching of HE teamwork. Specifically focusing on the performativity paradoxes of performing/organising, performing/learning, and performing/belonging, illuminated the lived experience of business educators navigating performativity with HE teamwork and their reactions to critical tension points in their required or perceived performativity. In this thesis the third published article presented in Chapter Five, conceptualises how business school educators negotiated the inherent stresses, conflicts, and tensions in their teaching to understand, react and influence their approaches to HE teamwork. Theoretically, the utility of transaction cost and paradox theories as heuristic conceptual lenses to understand the dynamic interactions for educators’ facilitating the teaching of teamwork is demonstrated. Conceptual understandings are expanded through the application of paradox theory in the educational context, contributing to the advancement of knowledge and/or professional practice acknowledged by the Tertiary Education Quality and Standards Agency (2018) as a core aspect of HE scholarship. This is a unique feature of this study, generating original contributions to the understanding of the scholarship of teaching and learning in the field of teamwork in the Australian business school context. Implications for theory and practice have wider application within HE and provide a sound basis for the development of teamwork as a requisite skill to satisfy not only the broader aspects of the employability agenda, but also advancement of knowledge in the field which has implications for future research, providing opportunities to broaden the scholarship of teaching and learning as it relates to the functionality of teamwork pedagogy

    Craft Sciences

    Get PDF
    The field of ‘Craft Sciences’ refers to research conducted across and within different craft subjects and academic contexts. This anthology aims to expose the breadth of topics, source material, methods, perspectives, and results that reside in this field, and to explore what unites the research in such diverse contexts as, for example, the arts, conservation, or vocational craft education. The common thread between each of the chapters in the present book is the augmented attention given to methods—the craft research methods—and to the relationship between the field of inquiry and the field of practice. A common feature is that practice plays an instrumental role in the research found within the chapters, and that the researchers in this publication are also practitioners. The authors are researchers but they are also potters, waiters, carpenters, gardeners, textile artists, boat builders, smiths, building conservators, painting restorers, furniture designers, illustrators, and media designers. The researchers contribute from different research fields, like craft education, meal sciences, and conservation crafts, and from particular craft subjects, like boat-building and weaving. The main contribution of this book is that it collects together a number of related case studies and presents a reflection on concepts, perspectives, and methods in the general fields of craft research from the point of view of craft practitioners. It adds to the existing academic discussion of crafts through its wider acknowledgement of craftsmanship and extends its borders and its discourse outside the arts and crafts context. This book provides a platform from which to develop context-appropriate research strategies and to associate with the Craft Sciences beyond the borders of faculties and disciplines
