A New Interpretivist Metasemantics for Fundamental Legal Disagreements
What does it take for lawyers and others to think or talk about the same legal topic—e.g., defamation, culpability? We argue that people are able to think or talk about the same topic not when they possess a matching substantive understanding of the topic, as traditional metasemantics says, but instead when their thoughts or utterances are related to each other in certain ways. And what determines the content of thoughts and utterances is what would best serve the core purposes of the representational practice within which the thought or utterance is located. In thus favoring a “relational model” in metasemantics, we share Ronald Dworkin's goal of explaining fundamental legal disagreements, and also his reliance on constructive interpretation. But what we delineate is a far more general and explanatorily resourceful metasemantics than what Dworkin articulated, which also bypasses some controversial implications for the nature of law that Dworkin alleged
Spin Hamiltonian for which the Chiral Spin Liquid is the Exact Ground State
We construct a Hamiltonian that singles out the chiral spin liquid on a
square lattice with periodic boundary conditions as the exact and, apart from
the two-fold topological degeneracy, unique ground state.Comment: 5 pages, no figure

First Energy and Angle differential Measurements of e^+e^- -pairs emitted by Internal Pair Conversion of excited Heavy Nuclei
We present the first energy and angle resolved measurements of e+e- pairs
emitted from heavy nuclei (Z>=40) at rest by internal pair conversion (IPC) of
transitions with energies of less than 2MeV as well as recent theoretical
results using the DWBA method, which takes full account of relativistic
effects, magnetic substates and finite size of the nucleus. The 1.76MeV E0
transition in Zr90 (Sr source) and the 1.77MeV M1 transition in Pb207 (Bi
source) have been investigated experimentally using the essentially improved
set-up at the double-ORANGE beta-spectrometer of GSI. The measurements prove
the capability of the setup to cleanly identify the IPC pairs in the presence
of five orders of magnitude higher beta- and gamma background from the same
source and to yield essentially background-free sum spectra despite the large
background. Using the ability of the ORANGE setup to directly determine the
opening angle of the e+e- pairs, the angular correlation of the emitted pairs
was measured. In the Zr90 case the correlation could be deduced for a wide
range of energy differences of the pairs. The Zr90 results are in good
agreement with recent theory. The angular correlation deduced for the M1
transition in Pb207 is in strong disagreement with theoretical predictions
derived within the Born approximation and shows almost isotropic character.
This is again in agreement with the new theoretical results.Comment: LaTeX, 28 pages incl. 10 PS figures; Accepted by Z.Phys.
Immorality and Irrationality
Does immorality necessarily involve irrationality? The question is often taken to be among the deepest in moral philosophy. But apparently deep questions sometimes admit of deflationary answers. In this case we can make way for a deflationary answer by appealing to dualism about rationality, according to which there are two fundamentally distinct notions of rationality: structural rationality and substantive rationality. I have defended dualism elsewhere. Here, I’ll argue that it allows us to embrace a sensible – I will not say boring – moderate view about the relationship between immorality and irrationality: roughly, that immorality involves substantive irrationality, but not structural irrationality. I defend this moderate view, and argue that many of the arguments for less moderate views turn either on missing the distinction between substantive and structural rationality, or on misconstruing it
