Keeping the word : On orality and literacy (with a sideways glance at Navajo)
This article investigates the relationship between "orality" and "literacy." I take as my starting point the discussion by Walter Ong (1982) of the shift in "consciousness" that resulted from the movement from an "oral culture" to a "literate culture." I discuss a number of specific examples of the relationship between orality and literacy. My purpose in these examples is to suggest that literacy and orality are kinds of specific linguistic ideologies (see Silverstein 1979) and that we need a much more complex understanding of literacy as an ideological position than Ong has offered. In this article, I wish to explore orality and literacy as complex and interacting notions. My purpose is not so much as to critique Ong (though there will be some of that), but rather to elaborate what we might mean by "orality" and "literacy" as on the ground, linguacultural phenomena (see Friedrich 1989).Not
Using Session Types for Reasoning About Boundedness in the Pi-Calculus
The classes of depth-bounded and name-bounded processes are fragments of the
pi-calculus for which some of the decision problems that are undecidable for
the full calculus become decidable. P is depth-bounded at level k if every
reduction sequence for P contains successor processes with at most k active
nested restrictions. P is name-bounded at level k if every reduction sequence
for P contains successor processes with at most k active bound names.
Membership of these classes of processes is undecidable. In this paper we use
binary session types to decise two type systems that give a sound
characterization of the properties: If a process is well-typed in our first
system, it is depth-bounded. If a process is well-typed in our second, more
restrictive type system, it will also be name-bounded.Comment: In Proceedings EXPRESS/SOS 2017, arXiv:1709.0004

Lung Cancer Care Before and After Medicare Eligibility.
Uninsured and underinsured near-elderly may not have timely investigation, diagnosis, or care of cancer. Prior studies suggest Medicare eligibility confers significant and substantial reductions in mortality and increases in health service utilization. We compared 2245 patients diagnosed with lung cancer at ages 64.5 to 65 years and 2512 patients aged 65 to 65.5 years, with 2492 patients aged 65.5 to 66 years (controls) in 2000 to 2005. Compared with controls, patients diagnosed with lung cancer before Medicare eligibility had no statistically significant differences in cancer stage, time to treatment, type of treatment, and survival. Study power was sufficient to exclude mortality reductions and health service utilization changes of the magnitude found in prior work, suggesting that typically, appropriate lung cancer care may be sought and delivered regardless of insurance status
Unusual Nernst effect suggestive of time-reversal violation in the striped cuprate LaBaCuO
The striped cuprate LaBaCuO ( undergoes several
transitions below the charge-ordering temperature = 54 K. From Nernst
experiments, we find that, below , there exists a large, anomalous
Nernst signal that is symmetric in field , and remains
finite as . The time-reversal violating signal suggests that, below
, vortices of one sign are spontaneously created to relieve interlayer
phase frustration.Comment: 5 pages, 4 figure
Reply to ``Comment on `Insulating Behavior of -DNA on the Micron Scale' "
In our experiment, we found that the resistance of vacuum-dried -DNA
exceeds at 295 K. Bechhoefer and Sen have raised a number of
objections to our conclusion. We provide counter arguments to support our
original conclusion.Comment: 1 page reply to comment, 1 figur
Superconductivity in Mg10Ir19B16
Mg10Ir19B16, a previously unreported compound in the Mg-Ir-B chemical system,
is found to be superconducting at temperatures near 5 K. The fact that the
compound exhibits a range of superconducting temperatures between 4 and 5 K
suggests that a range of stoichiometries is allowed, though no structural
evidence for this is observed. The compound has a large, noncentrosymmetric,
body centered cubic unit cell with a = 10.568 Angstrom, displaying a structure
type for which no previous superconductors have been reported.Comment: submitted to PR
