Some finite difference methods for a kind of GKdV equations

Abstract: In this paper, some finite difference schemes I, II, III and IV, are investigated and compared in solving a kind of mixed problem of generalized Korteweg-de Vries (GKdV) equations especially the relative errors. Both the numerical dispersion and the numerical dissipation are analysed for the constructed difference scheme I. The stability is also obtained for scheme I and the constructed predictor–corrector scheme IV by using a linearized stability method. Other two schemes, II and III, are also included in the comparison among these four schemes for the numerical analysis of different GKdV equations. The results enable one to consider the relative error when dealing with these kinds of GKdV equations. Copyright © 2006 John Wiley & Sons, Ltd.

Ecosystem services: nature's balance sheet.

Abstract: In the Research Article “Bringing ecosystem services into economic decision-making: Land use in the United Kingdom” (5 July, p. [45][1]), I. J. Bateman et al. summarize current efforts to assign economic value to ecosystem services. We add three factors that should be taken into account, based on life cycles and contribution of agricultural land use and associated habitats providing food. First, both income and expenditures should be included in valuation of ecosystem services. Expenditures are a major consideration in land-management decisions alongside income and value of products; recovery of food from ecosystems requires financial and other capital inputs. Second, using farm gate prices (i.e., the prices when leaving the farm, which are often lower than retail prices paid by consumers) to estimate the contributions of food from agriculture underestimates the product's value. In 2010, the base year for Bateman et al. 's analysis, total UK farm gate income was £4.34 billion, whereas the UK food and drink sector—including manufacture, wholesale, and retail—was valued at £86.2 billion ([ 1 ][2]). In current ecosystem assessment and economic valuation methodologies, the downstream economic and societal benefits value is not attributed to food production in ecosystem services. Third, agricultural land management influences ecosystem services beyond food provision. As Bateman points out, in Great Britain, agriculture directly influences about 75% of the land surface through management schemes and crop and livestock production activities. Many other ecosystem services recognized by the Millennium Ecosystem Assessment and UK National Ecosystem Assessment are thus directly and indirectly affected by agricultural land management. Economic valuation and accounting requires increased recognition of, and sensitivity to, interrelationships between services and the contributions made by land management to their availability. 1.

Abstract: poetry; and II., an Italian translation of Ovid, Trtstia III. 13, on the exile's birthday, with comments. The author has justified his separate study of natalician poetry in Latin, and has successfully carried through a careful investigation into the contents, implications and structure of poems of this class. We are also duly reminded of the Roman desire to honour birth anniversaries even of the dead. Suggestive criticism is contained in some of the comparative estimates—for instance, between Christian and pagan poets in their handling of parallel themes. It is instructive also to have emphasis laid on that closer respect for Roman tradition which in part explains why Tibullus did not follow Callimachus so far along the paths of mythological decoration as Propertius went. There is a mass of erudition in the notes, indicating intensive concentration on the author's theme. Much of this learning will be welcome to the scholar, while others, it is modestly suggested, can skip it (che il lettore non filologo potrd magari saltare). On p. 119 it seems far-fetched to regard comite in Statius as an echo of the Propertian cSmas. There is a table of corrections for errors in printing; but some slips have escaped notice: e.g., patri for patrui, p. 59, n. 2; Rotsthein for Rothstein, p. 90; Silvio for Silio, p. 136, and in the same line omne for omnes; adiunctos honori, from Ausonius, p. 165, will not scan; and, on p. 170, exuntur should be exutintur.
