对“符号矩阵”在文学批评实践中的反思

格雷马斯符号矩阵在国内文学批评实践中存在两种误读情况:一是在部分论著中将符号矩阵第三项和第四项位置颠倒,二是在函项赋值上存在很多偏差,并且缺失整合意识.通过重读符号矩阵,并借鉴杰姆逊运用这一模式分析文本的经典案例,可对上述不足加以修正.

Rapid reconstruction method of curved surface model in reverse design of bucket teeth

零件的曲面模型是获得其逆向设计数据等后续处理的关键环节。为了快速获得具有复杂外形和内腔的某型挖掘机斗齿的设计数据,研究了该斗齿点云曲面原型的获取方法。鉴于斗齿不同部位对逆向设计精度的要求不同,采用Imageware和Geomagic Studio对斗齿的内腔、销孔和外形点云分别进行曲面重构之后,再进行整个模型的曲面整合策略。介绍了应用两种软件完成斗齿曲面模型的主要处理过程及关键环节。该方法能快速获得符合精度要求的斗齿曲面模型,可行且高效,为斗齿曲面模型的实体化及其后续处理提供了可靠依据。     

Refugees and Cultural Transfer to Britain: An Introduction

This introduction has four purposes. It first of all gives a working definition of the refugee. It then outlines the main groups of refugees which have moved to Britain since the early modern period, focusing, more particularly, upon the nineteenth and twentieth centuries, which form the main focus of this volume. The article then introduces the reader to concepts of cultural transfer, especially as applied to migration and refugees, as well as outlining the main issues under consideration in the British case study, which forms the basis of this volume. Finally, the study introduces the main essays which follow and explains the structure adopted.

Short- and long-term effects of site factors on net N-mineralization and nitrification rates along an urban-rural gradient

Long- and short-term effects of urban site factors on net N-mineralization and nitrification rates were investigated in oak stands along an urban-rural land-use transect in the New York City metropolitan area. We used reciprocal transplants of undisturbed soil cores between urban and rural forests to determine the relative importance of long-term effects (mor vs. mull soils, quality of soil organic matter, and deposition of N) vs. short-term effects (soil temperature) of urban factors in controlling field N-transformation rates along the gradient. In addition, undisturbed soil cores from surface (A, Oe horizons) and subsurface (B horizon) soil were collected from urban, suburban, and rural stands and allowed to incubate in these respective sites to compare the net effect of all urban factors with transplanted-core results. The transplant experiment revealed that soil type (long-term) affected net N-mineralization and nitrification rates. Urban soils nitrified nearly 6.3 and 5.4 times more than rural soils incubating in urban and rural stands, respectively (p = 0.003 and p = 0.002, respectively). Similarly, in rural stands total accumulation of inorganic N was 87% higher in urban than in rural soils, whereas in urban stands, urban soils mineralized 83% more N than rural soils (p = 0.043 and 0.08, respectively). Comparing soils incubating in their native locations, urban soils incubating in urban stands mineralized more than 2.5 times the amount of N than rural soils incubating in the rural stands (p = 0.019). By contrast, urban soils incubating in urban stands exhibited a 8-fold increase in nitrification over rural soils incubating in rural stands (p = 0.008). As with the transplanted cores, the urban and suburban environments had a positive effect on net rates of N-mineralization and nitrification in both surface and subsurface layers of soil. The surface layer of suburban and urban stands had a 3- and 2.3-fold higher accumulation of net inorganic N than rural stands (ANOVA, p = 0.05). Similarly, in the subsurface layer both urban and suburban stands had 2.6-fold higher net N-mineralization rate than rural stands (ANOVA, p = 0.01). Along this urban-rural gradient, soils in oak stands exhibit higher net nitrification and, to a lesser extent, net N-mineralization rates in urban and suburban stands than in rural stands. Results from the transplant experiment and in situ measurements of surface and subsurface soil indicate that long-term effects (mor vs. mull soils, N deposition) contribute to the higher N-transformation rates in urban and suburban stands. As a result of these effects, urban and suburban stands have the potential for higher losses of N than rural stands.

Finite Sample Comparison of Parametric, Semiparametric, and Wavelet Estimators of Fractional Integration

In this paper we compare through Monte Carlo simulations the finite sample properties of estimators of the fractional differencing parameter, d. This involves frequency domain, time domain, and wavelet based approaches, and we consider both parametric and semiparametric estimation methods. The estimators are briefly introduced and compared, and the criteria adopted for measuring finite sample performance are bias and root mean squared error. Most importantly, the simulations reveal that (1) the frequency domain maximum likelihood procedure is superior to the time domain parametric methods, (2) all the estimators are fairly robust to conditionally heteroscedastic errors, (3) the local polynomial Whittle and bias-reduced log-periodogram regression estimators are shown to be more robust to short-run dynamics than other semiparametric (frequency domain and wavelet) estimators and in some cases even outperform the time domain parametric methods, and (4) without sufficient trimming of scales the wavelet-based estimators are heavily biased.
