Dynamic dialogue: a multi-perspective approach towards cultural competence
Interculturalism and race relations are becoming more complex as America becomes more diverse. Recent attention focused on universities’ admissions programs aimed at diversifying the student body only convey a segment of campus efforts addressing diversity. Curriculum development initiatives speak to diversity concerns through course topics centered on issues such as race and gender by stimulating conversations among students and the instructor. This article presents two models for integrating dynamic dialogues/conversations about race across academic curricula. These perspectives shed insight into the challenges of communicating in an intercultural environment. One model highlights attempts at integrating dynamic dialogue programmatically and the other approaches dynamic dialogue pedagogically, through instructor training. We use Banks’ (2007) approach to multicultural curriculum reform to examine the pedagogic and curricular transformations for each institution
Using Kappenman\u27s Model to Compare the Relative Fishing Power of 42-Foot Shrimp Trawls and 65-Foot Fish Trawls During Summer and Fall in the Western and North-Central Gulf of Mexico
Kappenman’s fishing power correction (FPC) model was used to compare the fishing efficiency between a 42-ft shrimp trawl and a 65-ft fish trawl towed simultaneously at 985 stations by the National Oceanic and Atmospheric Administration ship Oregon II in the western and north-central Gulf of Mexico. The shrimp trawl was consistently more efficient, both summer and fall, and regardless of whether using no./hr or kg/hr to calculate the FPC factors, for four species of fish, three species of crustaceans, and paper scallops. During summer, the shrimp trawl was more efficient, when using FPC factors calculated using no./hr as the catch per unit of effort (CPUE), at catching 13 of the 42 species of fish, 11 of the 12 species of crustaceans, and paper scallops. It was more efficient at catching 18 of the 42 species of fish, 10 of the 12 species of crustaceans, and paper scallops when FPC factors were calculated using kg/hr as the CPUE. In the fall, the shrimp trawl was more efficient, when using no./hr or kg/hr as the CPUE, at catching five species of fish, three species of crustaceans, and paper scallops. Fishing power correction factors were then compared between summer and fall seasons for 42 species of fish and 16 species of invertebrates. During summer, FPC values ranged from a low of 0.15 for Gulf menhaden to 4.94 for shoal flounder; fall FPC values ranged from 0.05 for yellow box crab to 2.52 for broad-striped anchovy. With the exception of three species, when using number of individuals caught per hour as the CPUE, all FPC factors were significantly different between summer and fall catches
Regional center for complex colonoscopy: yield of neoplasia in patients with prior incomplete colonoscopy
Background and Aims
Incomplete colonoscopy increases the risk of incident proximal colon cancer postcolonoscopy. Incomplete colonoscopy is often followed by barium enema or CT colonography. We sought to describe the yield of completion colonoscopy in a regional center for complex colonoscopy.
Methods
This is a retrospective cohort study of 520 consecutive patients referred to a single colonoscopist over a 14-year period for completion colonoscopy after a previous incomplete examination.
Results
Colonoscopy was completed to the cecum in 506 of 520 patients (97.3%). A total of 913 conventional adenomas was removed in 277 patients (adenoma detection rate 53.3%). There were 184 adenomas ≥ 1 cm in size or with advanced pathology. There were 525 serrated-class lesions removed in 175 patients, including 54 sessile serrated polyps in 26 patients and 41 hyperplastic polyps greater than 1 cm in 26 patients. Nine colorectal cancers were found. We estimated that approximately 57% of the conventional adenomas, 58% of the sessile serrated polyps, 27% of the hyperplastic polyps, and all 9 cancers detected by the completion colonoscopy were beyond the extent of the previous examination.
Conclusions
The yield of completion colonoscopy in a cohort of patients with previous failed cecal intubation was substantial. Regional centers for complex colonoscopy can provide high rates of cecal intubation in cases of incomplete colonoscopy and high yields of lesions in these cases. The regional center for complex colonoscopy is an important medical service
Научно-технический прогресс или безопасность человечества
Постепенное развитие общественного производства, его постоянное совершенствование являются фундаментальными закономерностями экономической жизни человечества. Они основываются на прогрессе науки и техники. Научно-технический прогресс за тысячелетия человеческой цивилизации прошел сложный и противоречивый путь развития. Это было вызвано тем, что именно технический прогресс, который осуществлялся на первых этапах развития общества, осуществлялся отдельно от научного прогресса до конца XVIII - начала XIX в. И только в период промышленной революции началось быстрое сближение научного и технического прогресса и возник целостный научно-технический прогресс.Gradual development of social production, its constant improvement of the fundamental laws of the economic life of mankind. They are based on the progress of science and technology. Scientific and technological progress for the millennium of human civilization has passed a complex and contradictory path of development. This was due to the fact that it was the technical progress that was carried out at the first stages of the development of society that was carried out separately from scientific progress until the end of the eighteenth and early nineteenth centuries. And only in the period of the industrial revolution did the rapid rapprochement of scientific and technological progress and the emergence of integral scientific and technological progress began
Wheat silage for dairy cattle
Wheat silage as a feed for dairy cows has become popular recently in Missouri, even though little information about nutrient content and optimum cutting stage is available. Some recent research at the University of Missouri-Columbia provides new information about wheat silage for dairy cows. This new information includes the changes in energy, protein, and minerals with stage of maturity at harvest and recommendations for cutting and storage. In general, most of this information probably applies to other small grain silages, such as oats and barley, for which similar information is scarce.R. L. Belyea, R. E. Ricketts , F. A. Martz, R.R.

A revision of the British Chronostratigraphy within the Last Glacial-Interglacial Cycle based on new evidence from Arclid, Cheshire UK
Of the 24 Greenland interstadials (GI) in the Last Glacial-interglacial cycle (LGIC) only five are conventionally recognised in Britain. This paper aims to improve understanding of the LGIC in Britain from a site at Arclid, Cheshire. Sediments were characterised and luminescence used to establish a chronology. This found that the Chelford Sand Formation spans 77-47 ka with sand deposited initially by aeolian but later by fluvial transportation. Coleoptera and Diptera from the basal peat lens provided a reconstruction for a heather-rich heathland environment grazed by large herbivores, with summer temperatures between 13-18° C, and winter temperatures between -14 and 1°C. Flies included the earliest records of the blood-sucking horsefly Haematopota pluvialis, and the soldierfly Chloromyia formosa. The overlying Stockport Sand Formation was deposited fluvioglacially between 47-41 ka with the upper Stockport Till formed by the advance of the last British icesheet after ~33 ka. Stenothermic beetle analysis from Arclid indicate similarities with results from other British mid LGIC sites, some of which are at or beyond the limit of radiocarbon dating and may be of a similar age to Arclid. Basal organic sediments found at Arclid along with other reassigned sites are proposed as a new Arclid Interstadial. A revised British LGIC chronostratigraphy has the Wretton, Chelford and Brimpton Interstadials and the previously suggested but not widely recognised Cassington Interstadial. The Arclid Interstadial occurred after these, but prior to the Upton Warren Interstadial complex. This closes the previous gap in interstadials between the Brimpton Interstadial and the Upton Warren Interstadial complex within the British chronostratigraphy
Fresnel filtering in lasing emission from scarred modes of wave-chaotic optical resonators
We study lasing emission from asymmetric resonant cavity (ARC) GaN
micro-lasers. By comparing far-field intensity patterns with images of the
micro-laser we find that the lasing modes are concentrated on three-bounce
unstable periodic ray orbits, i.e. the modes are scarred. The high-intensity
emission directions of these scarred modes are completely different from those
predicted by applying Snell's law to the ray orbit. This effect is due to the
process of ``Fresnel filtering'' which occurs when a beam of finite angular
spread is incident at the critical angle for total internal reflection.Comment: 4 pages, 3 figures (eps), RevTeX 3.1, submitted to Phys. Rev. Lett;

Language attitudes and use in a transplanted setting: Greek Cypriots in London
In this paper we explore language attitudes and use in the Greek Cypriot community in London, England. Our study is based on an earlier survey carried out in Nicosia, Cyprus and we compare attitudes to language and reported language use in the two communities. We thereby highlight the significance of sociolinguistic variables on similar groups of speakers. We further extend our investigation to include codeswitching practices in the London community.
\ud
Analysis of language attitudes and use within the Greek-Cypriot population of London, and comparisons with findings in Nicosia, reflect symbolic forces operating in the two contexts. Despite obvious differences between the two communities, (most obviously the official languages and distinct cultural backgrounds of the two nations), the Greek Cypriot Dialect continues to play an active role in both. English is however the ‘default choice‘ for young Cypriots in the UK and Standard Modern Greek occupies a much more limited role than in Cyprus. It is argued that differences in language attitudes and use can be interpreted in light of different market forces operating in the nation (i.e. Cyprus) and the Diaspora (i.e. UK)
