Under Siege : Journal Publishing in the 1990s
Budget cutbacks are the theme of the '90s, and all aspects of advanced education are under intense pressure from severely reduced federal and provincial funding. The realm of scholarly communication is no exception. At a time of rising production costs, reduced postal subsidies, and subscription cancellations from under-funded university libraries, publishers of scholarly journals are now faced with the outright elimination of funding sources such as the Scientific Publication Grants Program of the Natural Sciences and Engineering Research Council of Canada (NSERC). According to NSERC, the support of scientific journals is a "non-core program" and is therefore being terminated to allow more funding to be directed to research grants. It is difficult to understand how the dissemination of knowledge came to be defined as a non-core program. The goal of ensuring adequate funds for the direct costs of conducting research is certainly laudable. Nevertheless, the loss, through inadequate funding, of scholarly journals as a major forum for scientists to communicate the results of their work has serious consequences for the entire scientific endeavour. There is little point in funding research that will remain unknown to the broader academic community and to Canadian tax-payers who support that community. Such a move could easily result in the research being available only to a privileged few (relatively speaking) through informal networks of communication such as the Internet. ... The move to on-line publishing may somewhat ease the budgetary pressures on journal support programs and university libraries as more and more new journals are offered directly in the electronic media rather than in print. ... Until such time as the print journal has disappeared, publishers will continue to seek ways to make the production process as efficient and cost-effective as possible, while maintaining the quality and integrity of scholarly journals. ... Fiscally responsible journal management means maintaining subscriber rates that will cover the costs of production and distribution. But we need to look elsewhere to cover the myriad other costs associated with scholarly publishing. ..
Western Elements in the Early Thule Culture of the Eastern High Arctic
Excavations of Thule culture winter sites in the Bache Peninsula region on the east coast of Ellesmere Island have yielded a number of finds which indicate a strong relationship to cultural developments in the Bering Sea region. Specific elements under discussion include dwelling styles, clay pottery, needle cases, a brow band and harpoon heads. Evidence is presented suggesting an initial arrival of the Thule culture Inuit in the eastern Arctic around 1050 A.D
Targeting alphas can make coyote control more effective and socially acceptable
Research at the UC Hopland Research and Extension Center (HREC) has improved our understanding of how to reduce sheep depredation while minimizing the impact on coyotes. Analysis of a 14-year data set of HREC coyote-control efforts found that sheep depredation losses were not correlated with the number of coyotes removed in any of three time scales analyzed (yearly, seasonally and monthly) during corresponding intervals for the next 2 years. Field research using radiotelemetry to track coyotes supported and explained this finding. For example, in 1995, dominant âalphasâ from four territories were associated with 89% of 74 coyote-killed lambs; âbetasâ and transients were not associated with any of these kills. Relatively few coyotes were killing sheep, and these animals were difficult to capture by conventional methods at the time of year when depredation was highest. However, selective removal of only the problem alpha coyotes effectively reduced losses at HREC

Qwu?gwes - A Squaxin Island tribal heritage wet site, Puget Sound, USA
The Qwu?gwes wet site is located at the very head of Puget Sound in Washington State, USA (fig 1). Puget Sound has been referred to as an inland sea, but is better termed as a large glacially cut fjord that is approximately 145km long, running north to south, where the ocean salt water from the Pacific mixes with fresh water draining from the surrounding watersheds. Puget Sound was formed into the northâsouth fjord it is today by glaciers that advanced from the north at least four times, scouring and carving it for millions of years (Waitt & Thorson 1983). The Vashon Stade was the last major advance, reaching its maximum about 18,000 years ago, covering everything between the Olympic and the Cascade mountains and spreading as far south as our specific region of study. As the Vashon Stade retreated, its melting ice created a massive fresh water lake that released through the Black Lake spillway at the head of Eld Inlet, our site location, and down the Chehalis River drainage to the Pacific Ocean. Once the glaciers melted far enough north, the Straits of Juan de Fuca were open and salt water from the Pacific Ocean entered Puget Sound, making it the salt water âinland seaâ it is today (fig 1). Our research area encompasses the southern reaches of the traditional territory of the Lushootseed-speaking Coast Salish People and language family, sometimes referred to as Puget [Sound] Salish (Suttles & Lane 1990, 485â502; Thompson & Kinkade 1990, 38; fig 1). Few systematic archaeological investigations have occurred in this region, especially in the southern section of Lushootseed traditional territory, so this paper should be considered a much needed synthesis of a well-preserved waterlogged site. Qwu?gwes forms the main reference point for our synthesized presentations, and this work is based on the original papers presented by the authors at the 11th International Wetland Archaeology Research Project (WARP) conference in Edinburgh (21â24 September 2005). This joint investigation of the Squaxin Island Tribe and South Puget Sound Community College has been ongoing for several years and provides both a scientific and cultural perspective of the many findings. Earlier publications stress the basis of this joint co-operative effort and the need for co-ordinated scientific and Native cultural understandings and explanations (Foster & Croes 2002, 2004)
Current Status of Cord Blood Banking and Transplantation in the United States and Europe
Cord blood (CB) transplantation has expanded the ability of the transplantation community to meet the growing needs of their patients. Clinical data over the last decade show promising results in CB transplantation using blood from related as well as unrelated donors. Basic science continues to look for ways to expand the quality and quantity of CB. CB banks are now established around the world, with major efforts to standardize banking to facilitate regulation, collection, processing, and distribution as a way of providing the highest-quality CB for patient use. This review article discusses the current status of CB transplantation and banking in the United States and Europe
The Lupus Transit Survey For Hot Jupiters: Results and Lessons
We present the results of a deep, wide-field transit survey targeting Hot
Jupiter planets in the Lupus region of the Galactic plane conducted over 53
nights concentrated in two epochs separated by a year. Using the Australian
National University 40-inch telescope at Siding Spring Observatory (SSO), the
survey covered a 0.66 sq. deg. region close to the Galactic Plane (b=11 deg.)
and monitored a total of 110,372 stars (15.0<V<22.0). Using difference imaging
photometry, 16,134 light curves with a photometric precision of sigma<0.025 mag
were obtained. These light curves were searched for transits, and four
candidates were detected that displayed low-amplitude variability consistent
with a transiting giant planet. Further investigations, including spectral
typing and radial velocity measurements for some candidates, revealed that of
the four, one is a true planetary companion (Lupus-TR-3), two are blended
systems (Lupus-TR-1 and 4), and one is a binary (Lupus-TR-2). The results of
this successful survey are instructive for optimizing the observational
strategy and follow-up procedure for deep searches for transiting planets,
including an upcoming survey using the SkyMapper telescope at SSO.Comment: 27 pages, 9 figures, 4 tables. Accepted for publication in A
TESS Discovery of a Transiting Super-Earth in the Mensae System
We report the detection of a transiting planet around Mensae (HD
39091), using data from the Transiting Exoplanet Survey Satellite (TESS). The
solar-type host star is unusually bright (V=5.7) and was already known to host
a Jovian planet on a highly eccentric, 5.7-year orbit. The newly discovered
planet has a size of and an orbital period of 6.27
days. Radial-velocity data from the HARPS and AAT/UCLES archives also displays
a 6.27-day periodicity, confirming the existence of the planet and leading to a
mass determination of . The star's proximity and
brightness will facilitate further investigations, such as atmospheric
spectroscopy, asteroseismology, the Rossiter--McLaughlin effect, astrometry,
and direct imaging.Comment: Accepted for publication ApJ Letters. This letter makes use of the
TESS Alert data, which is currently in a beta test phase. The discovery light
curve is included in a table inside the arxiv submissio
