The Continuum

AbstractThe Continuum concept of pluralisation is often misunderstood. This paper aims to explain how records are embedded in the society that created them from the time of their creation and how they can be further embedded throughout their lifespan by adding metadata to them, placing them in context, making them accessible to those who will need them in the future and potentially sharing them with the broader society according to societal rules. The author proposes to use the concept of societal embeddedness, which indicates that pluralisation is not just about sharing in the future, but also about incorporating societal expectations in records and recordkeeping systems, to help explain the concept of pluralisation. She shows how using simple examples from everyday life and discussing the societal context of the creation and use of records can help explain Records Continuum concepts, and in particular the concept of pluralisation, to students from non-English speaking backgrounds.

Management Theories

This study provides a descriptive examination and traces the historical development of records management approaches, as well as their significance to the records management practice and their limitations. The study focuses on the records continuum model, developed in Australia's archival sciences field in recent years and discusses its implications for the practice of records and archival management. Prior to the emergence of the records continuum model, the life-cycle theory dominated most records management fields globally. The records continuum model responds – in ways that the life-cycle theory is unable to deal with the challenges of electronic records and proposes a new set of management thinking of the preservation of the electronic environment, in which contemporary institutions and their associated electronic records coexist. There appears to be insufficient literature on the practice of these two records management theories in the organizational context. To contribute to bridging this gap, this study analysed the major components of each records management theory and presents models of organizations built on these approaches. Therefore, the study examines the uses of the records continuum model and life-cycle theories within the broader field of archival research. The study is a literature review within a qualitative, interpretative paradigm. Relying on historical and narrative analysis, the findings established evidence of the practice of the records management theories in the organizations. The study concluded that records management practice in organizations can be enhanced, if specific factors within each records management approach are given adequate consideration in their application.

AbstractCollective cell migration is a fundamental process in embryonic development and tissue homeostasis. This is a macroscopic population-level phenomenon that emerges across hierarchy from microscopic cell-cell interactions; however, the underlying mechanism remains unclear. Here, we addressed this issue by focusing on epithelial collective cell migration, driven by the mechanical force regulated by chemical signals of traveling ERK activation waves, observed in wound healing. We propose a hierarchical mathematical framework for understanding how cells are orchestrated through mechanochemical cell-cell interaction. In this framework, we mathematically transformed a particle-based model at the cellular level into a continuum model at the tissue level. The continuum model described relationships between cell migration and mechanochemical variables, namely, ERK activity gradients, cell density, and velocity field, which could be compared with live-cell imaging data. Through numerical simulations, the continuum model recapitulated the ERK wave-induced collective cell migration in wound healing. We also numerically confirmed a consistency between these two models. Thus, our hierarchical approach offers a new theoretical platform to reveal a causality between macroscopic tissue-level and microscopic cellular-level phenomena. Furthermore, our model is also capable of deriving a theoretical insight on both of mechanical and chemical signals, in the causality of tissue and cellular dynamics.

The Continuum

The intrinsic feature of graphene honeycomb lattice is defined by its chiral index (n,m), which can be taken into account when using molecular dynamics. However, how to introduce the index into the continuum model of graphene is still an open problem. The present manuscript adopts the continuum shell model with single director to describe the mechanical behaviors of graphene. In order to consider the intrinsic features of the graphene honeycomb lattice—chiral index (n,m), the chiral-tube vectors of graphene in real space have been used for construction of reference unit base vectors of the shell model; therefore, the formulations will contain the chiral index automatically, or in an explicit form in physical components. The results are quite useful for future studies of graphene mechanics.
