Colorectal cancer is the second leading cause of death from cancer in the United States. It is third leading cause of cancer death in men behind lung and prostate respectively, and behind lung and ...breast in cancer deaths among women. More than 130,000 cases are diagnosed each year with over 56,000 of those patients dying. Six percent of the United States population will develop colorectal cancer in their lifetime.

Sampling an intact sequence of oceanic crust through lavas, dikes, and gabbros is necessary to advance the understanding of the formation and evolution of crust formed at mid-ocean ridges, but it has ...been an elusive goal of scientific ocean drilling for decades. Recent drilling in the eastern Pacific Ocean in Hole 1256D reached gabbro within seismic layer 2, 1157 meters into crust formed at a superfast spreading rate. The gabbros are the crystallized melt lenses that formed beneath a mid-ocean ridge. The depth at which gabbro was reached confirms predictions extrapolated from seismic experiments at modern mid-ocean ridges: Melt lenses occur at shallower depths at faster spreading rates. The gabbros intrude metamorphosed sheeted dikes and have compositions similar to the overlying lavas, precluding formation of the cumulate lower oceanic crust from melt lenses so far penetrated by Hole 1256D.
This article examines the historical development of the PhD in the discipline of history, and its Frankenstein-like transplantation into the body of fine art. It also examines the background of ...European iconophobia that, I shall argue, has made the assimilation of the visual arts into the modern university so problematic. Leading on from that, a major theme in this paper is examination of definitions of knowledge. Drawing on the works of phenomenological philosophers such as Croce, Dewey and Ricoeur, I argue that the artwork is a text or work that is equivalent to the written text, and, as such, it should be seen as the appropriate form for a fine art doctoral thesis.

The recent film, Braveheart, has been received by many in Scotland as a celebration of Scots nationhood, and as a portrayal of Scottish patriotism in the face of English territorial greed. Indeed, in ...the campaign leading up to the British general election in 1997, and the subsequent referendum on Scottish devolution, Braveheart was often cited as an example of Scottish mettle in the face of oppression, and the very word became a nationalist rallying cry. However, as this paper demonstrates, the film is actually constructed as a post-colonial, 'white-pioneer' myth of origin and ancestry which addresses and confirms a (mainly) American sense of cultural identity. The paper examines the origins of the Braveheart myth and the historical evidence surrounding the original William Wallace. It then traces the exportation of the Wallace legend to the British colonies in the 18th and 19th centuries and its eventual transformation into the Braveheart story of the 1990s.
Nurses' attitudes play an important role in the consistent practice of safe patient handling behaviors. The purposes of this study were to develop and assess the psychometric properties of a newly ...developed instrument measuring attitudes of nurses related to the care and safe handling of patients who are obese.
Phases of instrument development included (a) item generation, (b) content validity assessment, (c) reliability assessment, (d) cognitive interviewing, and (e) construct validity assessment through factor analysis.
The final data from the exploratory factor analysis produced a 26-item multidimensional instrument that contains 9 subscales.
Based on the factor analysis, a 26-item instrument can be used to examine nurses' attitudes regarding patients who are morbidly obese and related safe handling practices.
Marine sediments around volcanic islands contain an archive of volcaniclastic deposits, which can be used to reconstruct the volcanic history of an area. Such records hold many advantages over often ...incomplete terrestrial data sets. This includes the potential for precise and continuous dating of intervening sediment packages, which allow a correlatable and temporally constrained stratigraphic framework to be constructed across multiple marine sediment cores. Here we discuss a marine record of eruptive and mass‐wasting events spanning ∼250 ka offshore of Montserrat, using new data from IODP Expedition 340, as well as previously collected cores. By using a combination of high‐resolution oxygen isotope stratigraphy, AMS radiocarbon dating, biostratigraphy of foraminifera and calcareous nannofossils, and clast componentry, we identify five major events at Soufriere Hills volcano since 250 ka. Lateral correlations of these events across sediment cores collected offshore of the south and south west of Montserrat have improved our understanding of the timing, extent and associations between events in this area. Correlations reveal that powerful and potentially erosive density‐currents traveled at least 33 km offshore and demonstrate that marine deposits, produced by eruption‐fed and mass‐wasting events on volcanic islands, are heterogeneous in their spatial distribution. Thus, multiple drilling/coring sites are needed to reconstruct the full chronostratigraphy of volcanic islands. This multidisciplinary study will be vital to interpreting the chaotic records of submarine landslides at other sites drilled during Expedition 340 and provides a framework that can be applied to the stratigraphic analysis of sediments surrounding other volcanic islands.
