We present the results of a large-area survey for millisecond pulsars (MSPs) at moderately high galactic latitudes with the 64 m Parkes radio telescope, along with follow-up timing and optical studies of the newly-discovered pulsars and several others. Major results include the first precise measurement of the mass of a fully recycled pulsar and measurement of orbital period decay in a double neutron star binary system allowing a test of general relativity along with improved measurements of the neutron star masses. In a survey of approx. 4,150 square degrees, we discovered 26 previously unknown pulsars, including 7 "recycled" millisecond or binary pulsars. Several of these recycled pulsars are particularly interesting: PSR J1528-3146 is in a circular orbit with a companion of at least 0.94 solar masses; it is a member of the recently recognized class of intermediate mass binary pulsar (IMBP) systems with massive white dwarf companions. We have detected optical counterparts for this and one other IMBP system; taken together with optical detections and non-detections of several similar systems, our results indicate that the characteristic age consistently overestimates the time since the end of mass accretion in these recycled systems. This result implies that the pulsar spin period at the end of the accretion phase is not dramatically shorter than the observed period as is generally assumed. PSR J1600-3053 is among the best high-precision timing pulsars known and should be very useful as part of an ensemble of pulsars used to detect very low frequency gravitational waves. PSR J1738+0333 has an optical counterpart which, although not yet well-studied, has already allowed a preliminary measurement of the system's mass ratio. The most significant discovery of this survey is PSR J1909-3744, a 2.95 ms pulsar in an extremely circular 1.5 d orbit with a low-mass white dwarf companion. Though this system is a fairly typical low-mass binary pulsar (LMBP) system, it has several exceptional qualities: an extremely narrow pulse profile and stable rotation have enabled the most precise long-term timing ever reported, and a nearly edge-on orbit gives rise to a strong Shapiro delay signature in the pulse timing data which has allowed the most precise measurement of the mass of a millisecond pulsar: 1.438 ± 0.024 solar masses. Our accurate parallax distance measurement, d = 1.14 +0.08 / -0.07 kpc, combined with the mass of the optically-detected companion, 0.2038 ± 0.022 solar masses, will provide an important calibration for white dwarf models relevant to other LMBP companions. We have measured the decay of the binary period of the double neutron star system B2127+11C in the globular cluster M15. This has allowed an improved measurement of the mass of the pulsar, 1.3584 ± 0.0097 solar masses, and companion, 1.3544 ± 0.0097 solar masses, as well as a test of general relativity at the 3% level. We find that the proper motions of this pulsar as well as B2127+11A and B2127+11B are consistent with each other and with one published measurement of the cluster proper motion. We have discovered three binary millisecond pulsars in the globular cluster M62 using the 100-m Green Bank Telescope (GBT). These pulsars are the first objects discovered with the GBT. We briefly describe a wide-bandwidth coherent dedispersion backend used for some of the high precision pulsar timing observations presented here.

Cultures of Darkness

Night Travels in the Histories of Transgression

By: Bryan D. Palmer

Peasants, religious heretics, witches, pirates, runaway slaves, prostitutes and pornographers, frequenters of taverns and fraternal society lodge rooms, revolutionaries, blues and jazz musicians, beats, and contemporary youth gangs--those who defied authority, choosing to live outside the defining cultural dominions of early insurgent and, later, dominant capitalism are what Bryan D. Palmer calls people of the night. These lives of opposition, or otherness, were seen by the powerful as deviant, rejecting authority, and consequently threatening to the established order. Constructing a rich historical tapestry of example and experience spanning eight centuries, Palmer details lives of exclusion and challenge, as the "night travels" of the transgressors clash repeatedly with the powerful conventions of their times. Nights of liberation and exhilarating desire--sexual and social--are at the heart of this study. But so too are the dangers of darkness, as marginality is coerced into corners of pressured confinement, or the night is used as a cover for brutalizing terror, as was the case in Nazi Germany or the lynching of African Americans. Making extensive use of the interdisciplinary literature of marginality found in scholarly work in history, sociology, cultural studies, literature, anthropology, and politics, Palmer takes an unflinching look at the rise and transformation of capitalism as it was lived by the dispossessed and those stamped with the mark of otherness.

The Gulf Military Balance

The Missile and Nuclear Dimensions

By: Anthony H. Cordesman,Bryan Gold

The United States faces major challenges in dealing with Iran, the threat of terrorism, and the tide of political instability in the Arabian Peninsula. The presence of some of the world’s largest reserves of oil and natural gas, vital shipping lanes, and Shia populations throughout the region have made the peninsula the focal point of US and Iranian strategic competition. Moreover, large youth populations, high unemployment rates, and political systems with highly centralized power bases have posed other economic, political, and security challenges that the Gulf states must address and that the United States must take into consideration when forming strategy and policy.

Money, Mandates, and Local Control in American Public Education

By: Bryan Shelly

Pointing to the disparities between wealthy and impoverished school districts in areas where revenue depends primarily upon local taxes, reformers repeatedly call for the centralization of school funding. Their proposals meet resistance from citizens, elected officials, and school administrators who fear the loss of local autonomy. Bryan Shelly finds, however, that local autonomy has already been compromised by federal and state governments, which exercise a tremendous amount of control over public education despite their small contribution to a school system's funding. This disproportionate relationship between funding and control allows state and federal officials to pass education policy yet excuses them from supplying adequate funding for new programs. The resulting unfunded and underfunded mandates and regulations, Shelly insists, are the true cause of the loss of community control over public education. Shelly outlines the effects of the most infamous of underfunded federal mandates, the No Child Left Behind Act of 2001 (NCLB), and explores why schools implemented it despite its unpopularity and out-of-pocket costs. Shelly's findings hold significant implications for school finance reform, NCLB, and the future of intergovernmental relations.

Ski Films

A Comprehensive Guide

By: Bryan Senn

Skiing in movies, like the sport itself, grew more prevalent beginning in the 1930s, when it was a pastime of the elite, with depictions reflecting changes in technique, fashion and social climate. World War II saw skiing featured in a dozen films dealing with that conflict. Fueled by postwar prosperity, the sport exploded in the 1950s--filmmakers followed suit, using scenes on snow-covered slopes for panoramic beauty and the thrill of the chase. Through the free-spirited 1960s and 1970s, the downhill lifestyle shussed into everything from spy thrillers to beach party romps. The extreme sports era of the 1980s and 1990s brought snowboarding to the big screen. This first ever critical history of skiing in film chronicles a century of alpine cinema, with production information and stories and quotes from directors, actors and stuntmen.
