Boundary Crossing and Boundary Objects
Review of Educational Research, 2011Diversity and mobility in education and work present a paramount challenge that needs better conceptualization in educational theory. This challenge has been addressed by educational scholars with the notion of boundaries, particularly by the concepts of boundary crossing and boundary objects.

Accurate Boundary Conditions for Twin Boundary
Communications in Computational Physics, 2021In this paper a heterogeneous lattice with twin boundary is considered. The authors develop some accurate boundary conditions for treating the numerical boundary in the problem under consideration. These conditions include time history kernel (THK) treatment and matching boundary conditions (MBC).

Boundaries. Boundaries…Boundaries???
Current Opinion in Cell Biology, 2008One way to modulate transcription is by partitioning the chromatin fiber within the nucleus into the active or inactive domains through the establishment of higher-order chromatin structure. Such subdivision of chromatin implies the existence of insulators and boundaries that delimit differentially regulated chromosomal loci. Recently published data on

Proceedings of the 2003 international ACM SIGGROUP conference on Supporting group work, 2003
This paper presents a study of an organisation, which is undergoing a process transforming organisational and technological boundaries. In particular, we shall look at three kinds of boundaries: the work to maintain and change the boundary between the organisation and its customers; boundaries between competencies within the organisation; and ...

Capacity of the Boundary and of a Boundary Component
The Annals of Mathematics, 19541. In several existence and extremal problems on Riemann surfaces, it is useful to characterize the type of the surface by certain conformally invariant measures.

Viewing boundary 'objects' as boundary constructions
Proceedings of the 41st Annual Hawaii International Conference on System Sciences (HICSS 2008), 2008Empirical results from a qualitative study within an important North American aircraft engine manufacturing company allows us to propose an alternative framework for achieving effective knowledge sharing based on the boundary construction concept. Tapping into Latour's (1993) epistemological insights of mutual transformation, hybridization and inter ...

Boundaries and boundary violations
2012A personal boundary is a fundamental component of selfhood; it refers to the ability to define one's self as an independent individual deserving of fair, respectful, nonexploitive treatment that is informed by widely accepted standards of legal and human rights.

The International Journal of Psychoanalysis, 2007
In this contribution, the authors define and discuss the educational boundary in analytic training, which they believe is an often neglected and useful concept in psychoanalytic education. The framework on which their discussion rests includes the recent attention of psychoanalysts to issues of boundaries and ethics. Their understanding of how clinical

The boundary of a boundary principle: A unified approach
Foundations of Physics, 1986The boundary of a boundary principle in field theories is described. The difference in treatment of the principle in electrodynamics and general relativity is pointed out and reformulated in terms of underlying mathematical structure of the theories. The problem of unifying the treatment is formulated and solved. The role of E.

THE ‘NO BOUNDARY CONDITION’ OUTFLOW BOUNDARY CONDITION
International Journal for Numerical Methods in Fluids, 1997Summary: We use a one-dimensional model problem of advection-diffusion to investigate the treatment recently advocated by \textit{T. C. Papanastasiou, N. Malamataris} and \textit{K. Ellwood} [Int. J. Numer. Methods Fluids 14, No. 5, 587--608 (1992; Zbl 0747.76039)] to deal with boundary conditions at artificial outflow boundaries. Using finite elements
