Judaean Ethnicity and Christ-Following Voluntarism? A Reply to Steve Mason and Philip Esler
No full textThis is the author accepted manuscript. The final version is available from Cambridge University Press via the DOI in this record In NTS 63 (2017), Steve Mason and Philip Esler responded to an earlier article of mine by setting out their grounds for a categorical distinction between Judaean ‘ethnic’ identity and Christ-following voluntary association and by rejecting the idea that drawing this contrast could reflect or legitimate modern notions of implicit Christian superiority. In this reply, intended to clarify the issues at stake and the grounds for disagreement, questions are first raised about various aspects of the approach to ethnicity that Mason and Esler adopt, illustrating the main points with brief examples from relevant texts and contemporary scholarship. Specifically, I consider the value of multiple rather than singular categorisations, the idea that ethnicity should be seen as multiple, fluid and hybrid in character, the relationship between ethnicity and religion, and the contrast between real and fictive kinship. Finally, I return to the issue of the ways in which scholarship may reflect its contexts of production and the need to probe this critically, offering specific illustrations of the reasons for my claims. Whether my particular suggestions concerning the implications of the dichotomy between Judaean/Jewish ethnicity and ‘trans-ethnic’ Christian identity are right or wrong, I argue for the importance of critical reflection on the impact of contemporary location on historical reconstruction.Arts and Humanities Research Council (AHRC
Paul, Inclusion, and Whiteness: Particularising Interpretation
No full textThis is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this record.This article takes its point of departure from the effort to reflect critically on how my racial/ethnic identity shapes what I (and the academic tradition of which I am a part) see and ask (and do not see or ask) in our interpretative work. Selections from commentaries are used to illustrate the history of interpretation of Gal. 3.28, and the findings are interrogated in the light of questions and issues deriving from the field of ‘whiteness’ studies. For a start, such studies may provoke us to think about how far Christianness – and unspoken assumptions about its superiority – shapes what is said about this text (e.g., in the frequent contrast drawn between Jewish exclusivism and Christian inclusivism). Furthermore, we may ask about the particular location of this interpretative tradition not only in religious terms, but also in racial ones. The changing contours of interpretation help to show how it is, in part at least, shaped by its contexts of production in the white, Christian West: it may thus be ‘particularized’ in both religious and racial terms. Just as whiteness studies has criticized the tendency of the ‘white’ perspective to remain ‘unlabelled’, unspecific, implicitly ‘human’ and universal, so too we may critique the tendency of this tradition of biblical studies to avoid labelling and recognizing its own specificity. Doing so, moreover, may help us not only to acknowledge our own particularity, but also to recognize why we need the insights of differently located and embodied interpreters to reach towards richer insight. Recognizing and labelling the particularity of our own perspective is thus one step towards equalizing the value of the various (labelled and unlabelled) perspectives in biblical studies.I would also like to thank the Arts and Humanities Research Council of the UK for their support of the research project on which this essay draws (grant reference AH-M009149/1)
Discontinuous Galerkin Methods for Numerical Weather Prediction: DG in a large-eddy simulation
No full textThe coarse grid of numerical weather prediction and climate models requires parametrization models to resolve atmospheric processes that are smaller than the grid size. For parametrization development, these processes are simulated by a high resolution model. At the Royal Netherlands MeteorologicalInstitute, the Dutch Atmospheric Large-Eddy Simulation (DALES) is used. This three-dimensional high resolution model uses advection schemes that are too diffusive when steep gradients are present. In this thesis, an advection scheme based on the Discontinuous Galerkin (DG) method is implementedfor DALES.The DG method is known to be dispersive. To remove those non-physical oscillations, the moment limiter of Krivodonova is used. Krivodonova constructed the limiter for one- and two-dimensions. In this thesis the moment limiter and limiting order are derived for three-dimensions. DALES is a model based on the finite difference method and uses operational splitting. Therefore, the DG advection scheme needs a mapping from each cell average to all nodal values that are needed for one DG cell, and a mapping back, which we called mapping a and b respectively. Mappings a that are discussed are taking the cell average as value for all nodal points of the DG cell (cell average a), and taking the L -projection of the cell average to the continuous finite element space (L -projection). This thesis describes mappings b that calculate cell averages of nodal DG values (cell average b)and calculate the cell averages of the tendencies of DG values (cell average of tendency). Using cell average a combined with cell average of tendency, made the DG method as diffusive as the first order upwind scheme. Substituting the cell average a method with the L -projection, the DG method becamevery dispersive, meaning that there was not enough diffusion. At last, cell average b was tested with the L -projection. Its numerical results showed that the speed of the advection was slower than the theoretical velocity. Therefore, a method is suggested which does not need mappings. An option couldbe a supergrid that takes multiple DALES cells as a DG cell.Applied Mathematic
Increasing Distributed Generation Penetration using Soft Normally-Open Points
No full textThis paper considers the effects of various voltage control solutions on facilitating an increase in allowable levels of distributed generation installation before voltage violations occur. In particular, the voltage control solution that is focused on is the implementation of `soft' normally-open points (SNOPs), a term which refers to power electronic devices installed in place of a normally-open point in a medium-voltage distribution network which allows for control of real and reactive power flows between each end point of its installation sites. While other benefits of SNOP installation are discussed, the intent of this paper is to determine whether SNOPs are a viable alternative to other voltage control strategies for this particular application. As such, the SNOPs ability to affect the voltage profile along feeders within a distribution system is focused on with other voltage control options used for comparative purposes. Results from studies on multiple network models with varying topologies are presented and a case study which considers economic benefits of increasing feasible DG penetration is also given
Dg algebras with enough idempotents, their dg modules and their derived categories
No full textWe develop the theory dg algebras with enough idempotents and their dg modules and show their equivalence with that of small dg categories and their dg modules. We introduce the concept of dg adjunction and show that the classical covariant tensor-Hom and contravariant Hom-Hom adjunctions of modules over associative unital algebras are extended as dg adjunctions between categories of dg bimodules. The corresponding adjunctions of the associated triangulated functors are studied, and we investigate when they are one-sided parts of bifunctors which are triangulated on both variables. We finally show that, for a dg algebra with enough idempotents, the perfect left and right derived categories are dual to each other.The author is highly indebted to Alexander Zimmermann for the careful reading of these notes, for his comments and for his help in improving the presentation.

Religion, Ethnicity, and Way of Life: Exploring Categories of Identity
No full textThis is the final version. Available from the Catholic Biblical Association of America via the DOI in this recordRecent scholarship has raised questions about some of the most basic categories
traditionally used in the discipline of New Testament studies (and related fields),
notably that of ‘religion’, which has been argued to be anachronistic for the ancient
world. The category of ‘ethnicity’ has been proposed as a more appropriate label for
Judaism (or Judean identity) of the time, though the early Christian movement is less
often seen in these terms. However, both categories are shown to be modern
constructions which cannot be neatly separated or unproblematically applied to early
Jewish and Christian sources. In an attempt to avoid – or at least expose – some of the
problems of such categorisations, the study focuses on terms related to ‘way of life’,
exploring some of the ways in which both Jewish and early Christian depictions of
joining or leaving fit within this broad category. The results do not imply that we can
dispense with our modern analytical categories, but they do suggest that distinct
categorisations as either ‘religious’ or ‘ethnic’ are unlikely to prove convincing, and
cannot form a basis for distinguishing the category of Jewish/Judean ‘ethnic’ identity
from that of early Christian identity.Arts and Humanities Research Council (AHRC
