The American Bar Association: Its Organization, History and Achievements
The American Bar Association holds its fifty-first annual meeting in Seattle, Washington, July 25, 26, 27, 1928. This is the Semi-Centennial meeting of the Association and special preparations are being made to make the occasion notable, and it is therefore appropriate that the whole bar of Washington who have so courteously invited the National Association to Seattle this year, should know something about the organization, history and achievements of the largest and one of the oldest organizations of lawyers in the world. A considerable portion of the bar of Washington are already members of the National Association, and to them many of the things hereinafter stated are well known, but it is hoped that all reputable lawyers of the great state of Washington will be sufficiently interested in the affairs of the National Association, to join its ranks, and thereby assist in the important work which the future has in store for the advancement of the profession and the welfare of the Nation
An Assessment of the Appropriateness to the Royal Australian Air Force of a Masters Level Professional Program in Information Systems
This study assessed the appropriateness, to the Royal Australian Air Force RAAF, of a graduate professional program in Information Systems (IS) based on the Association for Computing Machinery’s ACM curriculum model. The ACM curriculum model is an archetype of graduate education in IS. Programs based on this model produce graduates with knowledge, skills, and abilities (KSAs) that are required by IS practitioners. The usefulness of twenty KSAs that underlie the ACM curriculum model were evaluated by 33 incumbents of RAAF information Systems Agencies and Directorate of Communications and Information Systems - Air Force. Although uncertain about the educational background suited to their requirements, the respondents found 17 of the KSAs at least somewhat useful, indicating that education based on the ACM curriculum model is appropriate. Recommendations include developing a RAAF IS education strategy based on the KSAs, promoting the benefits of IS education, using graduate diplomas in IS as an effective and efficient means of obtaining the necessary KSAs, and examining RAAF sponsored bachelor degrees in IS to ensure that appropriate KSAs are being provided. Future research should identify graduate diploma programs that provide the relevant KSAs presented
Forecasting pulsar timing array sensitivity to anisotropy in the stochastic gravitational wave background
Statistical anisotropy in the nanohertz-frequency gravitational-wave
background (GWB) is expected to be detected by pulsar timing arrays (PTAs) in
the near future. By developing a frequentist statistical framework that
intrinsically restricts the GWB power to be positive, we establish scaling
relations for multipole-dependent anisotropy decision thresholds that are a
function of the noise properties, timing baselines, and cadences of the pulsars
in a PTA. We verify that a larger number of pulsars, and factors
that lead to lower uncertainty on the cross-correlation measurements between
pulsars, lead to a higher overall GWB signal-to-noise ratio, and lower
anisotropy decision thresholds with which to reject the null hypothesis of
isotropy. Using conservative simulations of realistic NANOGrav datasets, we
predict that an anisotropic GWB with angular power may
be sufficient to produce tension with isotropy at the
() level in near-future NANOGrav data with a ~yr baseline. We
present ready-to-use scaling relationships that can map these thresholds to any
number of pulsars, configuration of pulsar noise properties, and sky coverage.
We discuss how PTAs can improve the detection prospects for anisotropy, as well
as how our methods can be adapted for more versatile searches.Comment: Submitted to ApJ. Comments welcom
America is not losing its religion – population trends mean thatit is simply becoming more religiously diverse.
A recent Pew study found that there has been an increase in the number of Americans who claim to have ‘no-religion’. Does this mean that religion in the U.S. is on the way out? In new research which examines data from three national surveys, R. Khari Brown, Robert Joseph Taylor, and Linda M. Chatters find that African Americans and African Caribbean Americans are less likely than Non-Hispanic Whites, Hispanic Americans, and Asian Americans to identify as non-religious, with the latter group the most likely to identify as non-religious. They write that the recent shifts in religious affiliation may have less to do with Americans abandoning religion to America shifting towards increasing religious diversity
Supermassive Black-hole Demographics & Environments With Pulsar Timing Arrays
Precision timing of large arrays (>50) of millisecond pulsars will detect the
nanohertz gravitational-wave emission from supermassive binary black holes
within the next ~3-7 years. We review the scientific opportunities of these
detections, the requirements for success, and the synergies with
electromagnetic instruments operating in the 2020s.Comment: Submitted to the Astro2020 Decadal Survey. One of 5 core white-papers
