Boundary Formation and Cultural Construction: How do Chinese andIndian Immigrant Converts Understand Religious Identity?
Most scholars study immigrants\u27 religious lives in a vacuum, paying little attention to the religious lives of people who switch from one religious tradition to another. This article relies on interviews with Chinese and Indian immigrant converts in the U.S. to provide a unique comparative perspective on the religious lives of Asian immigrant converts, with a specific focus on their identity construction processes. Findings indicate that Chinese and Indian immigrants establish different types of boundaries, but form similar cultural content within their identities. I debunk the assumption in existing theories that religious conversion is an either/or transition
Spin-Up/Spin-Down models for Type Ia Supernovae
In the single degenerate scenario for Type Ia supernova (SNeIa), a white
dwarf (WD) must gain a significant amount of matter from a companion star.
Because the accreted mass carries angular momentum, the WD is likely to achieve
fast spin periods, which can increase the critical mass, , needed for
explosion. When is higher than the maximum mass achieved by the WD,
the WD must spin down before it can explode. This introduces a delay between
the time at which the WD has completed its epoch of mass gain and the time of
the explosion. Matter ejected from the binary during mass transfer therefore
has a chance to become diffuse, and the explosion occurs in a medium with a
density similar to that of typical regions of the interstellar medium. Also,
either by the end of the WD's mass increase or else by the time of explosion,
the donor may exhaust its stellar envelope and become a WD. This alters,
generally diminishing, explosion signatures related to the donor star.
Nevertheless, the spin-up/spin-down model is highly predictive. Prior to
explosion, progenitors can be super- WDs in either wide binaries with
WD companions, or else in cataclysmic variables. These systems can be
discovered and studied through wide-field surveys. Post explosion, the
spin-up/spin-down model predicts a population of fast-moving WDs, low-mass
stars, and even brown dwarfs. In addition, the spin-up/spin-down model provides
a paradigm which may be able to explain both the similarities and the diversity
observed among SNeIa.Comment: Submitted to ApJ Letter
Semi-analytic calculation of the monopole order parameter in QCD
The monopole order parameter of QCD is computed in terms of gauge invariant
field strength correlators. Both quantities are partially known from numerical
simulations on the lattice. A new insight results on the structure of the
confining vacuum.Comment: Talk presented at QCD06, Montpellier 3-7 July 2006. To appear in the

Short-duration lensing events: II. Expectations and Protocols
Ongoing microlensing observations by OGLE and MOA regularly identify and
conduct high-cadence sampling of lensing events with Einstein diameter crossing
time, tau_E, of 16 or fewer days. Events with estimated values of tau_E of one
to two days have been detected. Short duration events tend to be generated by
low-mass lenses or by lenses with high transverse velocities. We compute the
expected rates, demonstrate the expected ranges of parameters for lenses of
different mass, and develop a protocol for observing and modeling
short-duration events. Relatively minor additions to the procedures presently
used will increase the rate of planet discovery, and also discover or place
limits on the population of high-speed dim stars and stellar remnants in the
vicinity of the Sun.Comment: 17 pages; 3 figures; submitted to ApJ 3 July 200
Describing Sr2RuO4 superconductivity in a generalized Ginzburg--Landau theory
We propose a simple explanation of unconventional thermodynamical and
magnetic properties observed for Sr2RuO4. Actually, our two-phase model of
superconductivity, based on a straight generalization of the Ginzburg-Landau
theory, does predict two jumps in the heat capacity as well as a double curve
for the dependence of the critical temperature on an external magnetic field.
Such theoretical previsions well agree with the currently available
experimental data for Sr2RuO4Comment: revtex, 9 pages, 1 eps figur
Fully Packed O(n=1) Model on Random Eulerian Triangulations
We introduce a matrix model describing the fully-packed O(n) model on random
Eulerian triangulations (i.e. triangulations with all vertices of even
valency). For n=1 the model is mapped onto a particular gravitational 6-vertex
model with central charge c=1, hence displaying the expected shift c -> c+1
when going from ordinary random triangulations to Eulerian ones. The case of
arbitrary n is also discussed.Comment: 12 pages, 3 figures, tex, harvmac, eps
On the canonical divisor of smooth toroidal compactifications
In this paper, we show that the canonical divisor of a smooth toroidal
compactification of a complex hyperbolic manifold must be nef if the dimension
is greater or equal to three. Moreover, if we show that the numerical
dimension of the canonical divisor of a smooth -dimensional compactification
is always bigger or equal to . We also show that up to a finite \'etale
cover all such compactifications have ample canonical class, therefore refining
a classical theorem of Mumford and Tai. Finally, we improve in all dimensions
the cusp count for finite volume complex hyperbolic manifolds given
in [DD15a].Comment: Title shortened to match published versio
Does an International Academic Environment Promote Study Abroad?
Although many studies on international student mobility have examined the impact of individual factors (e.g., gender, age, family background) on students’ decision to study abroad, much less attention has been devoted to the role played by the institutional climate and characteristics of one’s home university. Using data from an Italian survey containing information on a large number of university students, this research investigated the extent to which a more international academic environment incentivizes students to participate in study abroad programs. A logit model was developed to estimate the effect that the degree of internationalization of one’s home university has on the probability that its students will study abroad, while controlling for several student-level factors. The empirical estimates indicate that this effect is significant, suggesting that being part of an international academic environment, where domestic students can interact more frequently with international students, helps motivate them to undertake study abroad. This result stresses the importance of engaging domestic students in the internationalization process of their universities
Gauge-invariant nonlocal quark condensates in QCD
We study, by numerical simulations on a lattice, the behaviour of the
gauge-invariant nonlocal quark condensates in the QCD vacuum both in the
quenched approximation and with four flavours of dynamical staggered fermions.
The correlation length of the condensate is determined to be roughly twice as
big as in the case of the gluon field strength correlators.Comment: LATTICE98(confine
