Intercultural Communication: Pre-Departure Orientation for Study Abroad Students
International education in the United States has become increasingly diverse. No longer is study abroad in higher institutions only accessible to the affluent, white privileged class. With this changing demographic in our student population, so does the need of how we prepare our student cohorts for their study abroad experience. The Intercultural Communication: Pre-Departure Orientation for Study Abroad Students is a project designed to start the process of intercultural communication skills building prior to a student’s departure. After exploring the literature about cross-cultural communication, identity formation and cultural humility, this project provides educators with an intercultural communication skill building pre-departure orientation that is ready for implementation. This orientation has been developed in such a way that revolve around cultural awareness and understanding, along with the notion of constant self-reflection. This project also offers recommendations on implementation and limitations
First CMB Constraints on Direction-Dependent Cosmological Birefringence from WMAP-7
A Chern-Simons coupling of a new scalar field to electromagnetism may give
rise to cosmological birefringence, a rotation of the linear polarization of
electromagnetic waves as they propagate over cosmological distances. Prior work
has sought this rotation, assuming the rotation angle to be uniform across the
sky, by looking for the parity-violating TB and EB correlations a uniform
rotation produces in the CMB temperature/polarization. However, if the scalar
field that gives rise to cosmological birefringence has spatial fluctuations,
then the rotation angle may vary across the sky. Here we search for
direction-dependent cosmological birefringence in the WMAP-7 data. We report
the first CMB constraint on the rotation-angle power spectrum for multipoles
between L = 0 and L = 512. We also obtain a 68% confidence-level upper limit of
1 degree on the square root of the quadrupole of a scale-invariant
rotation-angle power spectrum.Comment: 14 pages, 12 figures, 4 tables; accepted to PR
Delensing CMB Polarization with External Datasets
One of the primary scientific targets of current and future CMB polarization
experiments is the search for a stochastic background of gravity waves in the
early universe. As instrumental sensitivity improves, the limiting factor will
eventually be B-mode power generated by gravitational lensing, which can be
removed through use of so-called delensing algorithms. We forecast prospects
for delensing using lensing maps which are obtained externally to CMB
polarization: either from large-scale structure observations, or from
high-resolution maps of CMB temperature. We conclude that the forecasts in
either case are not encouraging, and that significantly delensing large-scale
CMB polarization requires high-resolution polarization maps with sufficient
sensitivity to measure the lensing B-mode. We also present a simple formalism
for including delensing in CMB forecasts which is computationally fast and
agrees well with Monte Carlos.Comment: typos correcte
