Resurrection in Mark 12: Refining the Covenant Hypothesis
The defence of resurrection in Mk 12.18-27 has been understood in various ways, based on different reconstructions of the logic of Jesusâ citation of Exod. 3.6. These various approaches may be generally grouped under two broad categories: âpresent relationshipâ hypotheses and âcovenant/contextâ hypotheses. This study evaluates those approaches, seeking to critique the existing covenant/context proposals of F. Dreyfus (1959) and Bradley R. Trick (2007) and extend their insights in new directions. In doing so, it focuses on citation context and similar reasoning in other early Jewish and Christian texts, including an overlooked analogue in Heb. 11. It will be argued that this context and these analogues lend support to a revised version of the covenant/context hypothesis that understands Mk 12 as predicating resurrection on divine faithfulness to the covenant between God and the patriarchs
In and Out of Egypt: the Conceptual Location of Ancient Alexandria, and a Paradox for Alexandrian Judaism?
A two-part paper. The first part revisits the conceptual relationship of Alexandria to Egypt by conducting a brief yet broad survey of ancient sources from the founding of Alexandria (c. 331 BCE to 300 CE). Particular attention is paid to Jewish perspectives, given our focus on Alexandrian Judaism and Egyptian Judaism more broadly. The second part of the paper turns to the âparadoxâ of Egyptian Judaism, sketching the background to this paradox in Jewish tradition before considering the strength of the evidence for the recognition and mitigation of the paradox in antiquity
Submarine films as narratives of masculinity
The research for this thesis is on representations of masculinity in Anglo-American submarine films since 1943. The discussion will draw on relevant work on the representation of masculinity and popular cinema in film and cultural studies. In particular, the thesis will account for the notion of hegemony in relation to masculinity in the submarine film. Further, the notion of hegemonic masculinity will be addressed in terms of four key claims. These are as follows: that relations between groups are characterised solely by domination and subordination, that a singular hegemonic masculinity prevails at anyone time, that this masculinity is coherent, and that hegemonic masculinity is consistently dominant in relations of power.
Through the reading of the films, this thesis will critique the notion of hegemonic masculinity in the following terms: a] the recurrent concern with the group emphasises teamwork and cooperation rather than domination and subordination. Even where these relations operate at the level of fantasy, they can suggest utopian possibilities of mutuality. b] This preoccupation with teamwork shows that the struggle between competing masculinities endorses difference in masculinity, not just a hegemonic masculinity. c] Rather than privileging hegemonic masculinity as coherent, this struggle leads to alliances between masculinities, in which hegemonic masculinity has to negotiate contradictions in masculinity. d] This account of submarine films therefore shows that masculinity involves the complex negotiation of differences and not solely the consistent privileging of hegemonic masculinity.
The analysis will be organised into chapters that derive specifically from the following thematic concerns within the case study: nature, the masculine body, men's friendships, rationality, vision and power, ideological processes, and the submarine as masculine space. Through the discussion of these themes and the developments in submarine films, the thesis will show the extent to which representations of masculinity in the case study conform to assumptions about hegemonic masculinity and popular film
GridSweep Simulation: Measuring Subsynchronous Impedance Spectra of Distribution Feeder
Peaks and troughs in the subsynchronous impedance spectrum of a distribution
feeder may be a useful indication of oscillation risk, or more importantly lack
of oscillation risk, if inverter-based resource (IBR) deployments are increased
on that feeder. GridSweep is a new instrument for measuring the subsynchronous
impedance spectra of distribution feeders. It combines an active probing device
that modulates a 120-volt 1-kW load sinusoidally at a user-selected GPS-phase
locked frequency from 1.0 to 40.0 Hz, and with a recorder that takes
ultra-high-precision continuous point-on-wave (CPOW) 120-volt synchrowaveforms
at 4 kHz. This paper presents a computer simulation of GridSweep's probing and
measurement capability. We construct an electromagnetic transient (EMT)
simulation of a single-phase distribution feeder equipped with multiple
inverter-based resources (IBRs). We include a model of the GridSweep probing
device, then demonstrate the model's capability to measure the subsynchronous
apparent impedance spectrum of the feeder. Peaks in that spectrum align with
the system's dominant oscillation modes caused by IBRs.Comment: 10 pages, 18 figure
Solving partial differential equations with waveguide-based metatronic networks
Photonic computing has recently become an interesting paradigm for high-speed
calculation of computing processes using light-matter interactions. Here, we
propose and study an electromagnetic wave-based structure with the ability to
calculate the solution of partial differential equations in the form of the
Helmholtz wave equation. To do this, we make use of a network of interconnected
waveguides filled with dielectric inserts. In so doing, it is shown how the
proposed network can mimic the response of a network of T-circuit elements
formed by two series and a parallel impedance, i.e., the waveguide network
effectively behaves as a metatronic network. An in-depth theoretical analysis
of the proposed metatronic structure is presented showing how the governing
equation for the currents and impedances of the metatronic network resembles
that of the finite difference representation of the Helmholtz wave equation.
Different studies are then discussed including the solution of partial
differential equations for Dirichlet and open boundary value problems,
demonstrating how the proposed metatronic-based structure has the ability to
calculate their solutions.Comment: 23 pages, 4 figures, 69 reference
Amplitude controlled electromagnetic pulse switching using waveguide junctions for high-speed computing processes
Performing computational tasks with wave-based devices is becoming a
groundbreaking paradigm that can open new opportunities for the next generation
of efficient analogue and digital computing systems. Decision-making processes
for switching and routing of signal is fundamental for computing as it enables
the transfer of information from one to many (or single) blocks within a
system. Here, we propose and demonstrate a technique for the design of
pulse-based switching devices for the computing of fundamental decision-making
processes. In our technique, we encode information from multiple channels as
transverse electromagnetic (TEM) pulses of varying amplitudes and polarities
propagating through interconnected parallel plate waveguides modelled as simple
transmission lines. An in-depth description of our technique is presented
showing how switching and routing of information can be engineered by correctly
exploiting the linear splitting and superposition of multiple pulses traveling
through waveguide junctions. To demonstrate the potential of our technique for
computing, we develop two devices: a comparator which can calculate the largest
value between two real-valued numbers and a pulse director which exploits the
reciprocity of waveguide junctions to create a similar yet different
performance of a traditional AND gate (emulating its performance via our
analogue linear system). These findings may open new pathways and possibilities
for high-speed electromagnetic pulse-based computing systems.Comment: 22 pages, 6 figure

MOF Decomposition and Introduction of Repairable Defects Using a Photodegradable Strut
International audiencePhotoswitchable components can modulate the properties of metal organic frameworks (MOFs); however, photolabile building blocks remain underexplored. A new strut NPDAC (2ânitroâ1,4âphenylenediacetic acid) that undergoes photodecarboxylation has been prepared and incorporated into a MOF, using postâsynthetic linker exchange (PSLE) from the structural analogue containing PDAC (pâphenylenediacetic acid). Irradiation of NPDACâMOF leads to MOF decomposition and concomitant formation of amorphous material. In addition to complete linker exchange, MOFs containing a mixture of PDAC and NPDAC can be obtained through partial linker exchange. In NPDAC30âMOF, which contains approximately 30â% NPDAC, the MOF retains crystallinity after irradiation, but the MOF contains defect sites consistent with loss of decarboxylated NPDAC linkers. The defect sites can be repaired by exposure to additional PDAC or NPDAC linkers at a much faster rate than the initial exchange process. The photoremoval and replacement process may lead to a more general approach to customizable MOF structures
