Racial Conflict in the United States of America : A Deconstructive Perspective on Native Speaker by Changrae Lee

Written about the time of the Golden Venture incident, Chang-rae Lee’s Native Speaker makes a particular reference to that incident, whereby implying that particular immigrants, on the grounds of their racial identities, are mistreated and considered as aliens by some Americas. While some whites discriminate against immigrants, there is widespread ethnic tension between Korean Americans and African Americans. Significantly, racial conflict between Koreans and blacks and the racist attitude of some whites toward immigrants are mirrored in the relationship between the Korean-American protagonist Henry and his American wife Lelia. That is, due to their different racial identities they do not understand each other and they always argue. However, toward the end of the novel, Henry and Lelia come to understand each other. While ethnic conflict between Koreans and blacks and certain whites’ discriminatory attitudes toward immigrants is serious one, the novel suggests the unimportance of racial identity. In other words, the novel concludes that there is no discriminatory treatment of immigrants and, in fact, every one is a native Speaker in America. In the novel there is no message of how racial conflict could be resolved. However, this essay suggests that by investigating how the tension between Henry and Lelia is resolved, one could suggest a solution for the ethnicity problem in America and in real life.

Acoustic Variability in the Production of English Vowels by Native and Non-Native Speakers

The features of non-native speech which distinguish it from native speech are often difficult to pin down. It is possible to be a native speaker of any of a vast number of varieties of English. These varieties each have their phonetic characteristics which allow them to be identified by speakers of the varieties in question and by others. The phonetic differences between the accents represented by these varieties are very great. It is impossible to indicate any particular configuration of vowels in the acoustic vowel space or set of consonant articulations which all native-speaker varieties of English have in common and which non-native speakers do not share. This study considers the vowel quality in a single word by native and non-native speakers.

Relative durations of post-vocalic consonants in readaloud Spanish by native Swedish L2-learners

Prosody is said to be a persistent feature in foreign accents, particularly in the speech of adult learners. Native Swedish speakers have been reported to lengthen vowels in Spanish as well as post-vocalic consonants in English and German, more than native speakers of the respective languages. The aim of the present study is to examine whether native Swedish learners of Spanish produce increased postvocalic consonant durations in a reading aloud exercise. The text contains certain words that could be expected to trigger complementary consonant lengthening in native Swedish speakers. The result shows that there is no general tendency for native Swedes to lengthen post-vocalic consonants more than native speakers of Spanish in the present speech material. There are examples of longer consonant durations in the speech of the native,Swedish subjects, but it could be a coincidence. A conclusion is that the text used in the study, and probably Spanish as a language, contains few words that are ideal for triggering lengthening of post-vocalic consonants in native Swedish speakers.

Resistência do solo à penetração e ao cisalhamento em diversos usos do solo em áreas de preservação permanente

The soil resistance to penetration and shear can be used as indicators of soil compaction and to indicate the susceptibility of a soil to erosion. The objective of this study was to quantify and compare the impact provided by different land uses in a haplic cambissol in areas of permanent preservation, from the soil resistance to penetration and shear. The experimental area was located in an area of permanent preservation, the sub-basin of the Ribeira Iguape River - SP, with different land uses: banana cultivation - CBAN, degraded pasture - PDEG, silvopastoral system - MPIS and native forest - MNAT. The test for resistance to penetration was accomplished with a digital penetrometer compaction of manual effort, to a depth of 40 cm. The soil shear strength was determined by Vane Test at a depth between 0 and 5 cm. The degraded pasture was similar to native forest, with less resistance to penetration. The banana cultivation and silvopastoral system were the land uses with the highest resistance to penetration, bringing serious risk of erosion in areas of permanent preservation. The soil under native forest had lower shear strength. The cultivation of bananas, degraded pasture and silvopastoral system were the land uses with higher shear strength of soil, indicating that the use of these soils in areas of permanent preservation is promoting the same compression.

Atributos de qualidade de solos sob dois diferentes tipos de manejo no município de Ibiúna/SP, Brazil

Agricultural activity has direct consequences on the soil and water quality. Thus, assessing environmental impacts of this vital economic activity, through soil attribute analysis, is essential to the proposal of alternatives. The aim of this study was to analyze soil quality under different land management practices, conventional and organic. The study was carried out in a watershed of the Ibiuna municipality, SP, Brazil, an important supplier of agricultural products for the São Paulo metropolitan area. A hundred samples were collected, 20 in each type of land use: reforested areas, native vegetation, pasture, conventional cultivation and organic cultivation. The soil resistance to penetration, its pH (in water and KO), electrical conductivity, bulk density, particle density, porosity, soil color, soil texture and the percentages of carbon and nitrogen were analyzed. The data were statistically analyzed, searching for significant differences. The results of soil analysis showed great similarity between the organic and conventional culture, with no statistical differences. However, organic cultivation showed greater similarity to the soil of native vegetation in the percentage of carbon and nitrogen in soils compared to conventional culture. Thus, the discussion begins on a topic very little explored so far, and the results obtained should be further studied.

Temperature and Scarification Effects on the Germination of Syagrus picrophylla Seeds, a Brazilian Native Palm

Syagrus picrophylla belongs to the Arecaceae family. Its propagation is made by seeds; however there is a lack of information in the literature about its seed germination. The objective of this work was to evaluate the effects of temperature and scarification on the germination of S. picrophylla seeds. The experiment was carried out at the State University of São Paulo, Jaboticabal Campus, Brazil. The experimental design was entirely randomized in a factorial arrangement 5 x 2 (five temperature conditions combined with or without mechanical scarification. The number of germinated seeds that showed primary root protrusion was noted daily, and when the germination was stabilized, the germination (%G) and germination rate (GR) were calculated. The analysis of variance (ANOVA) was carried out for means comparing by the Tukey test at 5% confidence level. It was concluded that the greatest %G were obtained at 20-30 degrees C (62%) and 25-35 degrees C (59%) alternated temperatures; %G and GR were similar for both scarified and non-scarified seeds, and there was a faster germination at 20-30 degrees C alternated temperature.

The cultivation of the soil causes changes in physical attributes, depending on the intensity of preparation and management. The objective of this work was to evaluate the degree of modification of some physical properties of soil mid the S index, comparing areas of Pasture of grass Tanzania (Panicum maximum) and native forest with an area under maize (Zea mays L.) irrigated bay, a central pivot. The study was conducted in three areas within the Agency of Technology Agribusiness Paulista (APTA) Regional High Mogiana, located in Colina, SP. The experimental design was split plot in a factorial 3 x 3, with 4 replications, where the plots were installed in areas of Cultivation of corn, pasture and forest in the depths 0-0.1 m, 0.1-0.2 m 0.2-0.3 m. The physical attributes of soil were: resistance to penetration (RP), bulk density (Ds), microporosity (Micro), macroporosity (Macro), total volume of pores (VTP) and water retention in soil. The native forest had the best physical condition of soil in all parameters examined. The use of land and pasture with corn altered the physical structure of it, evidenced by the increase in penetration resistance and soil density and, reduction in macroporosity. The level of degradation of the managed soil was considered low, index S (<0035). The replacement of pasture by the corn crop in the soil tillage system provided a conventional mild improvement in soil physical characteristics.

Influência do manejo do solo nas propriedades químicas e físicas em topossequência na bacia do rio Araguaia, Estado do Tocantins

A conversão do Cerrado nativo em áreas de exploração agrícola pode modificar os processos de decomposição e síntese da matéria orgânica do solo e, assim, na disponibilidade de nutrientes. Objetivou-se avaliar as propriedades químicas e físicas do solo em topossequência caracterizada por apresentar uso com pastagem cultivada com Brachiaria brizantha ao lado do Cerrado nativo, na camada de 0- 15 cm de profundidade. O estudo foi realizado no município de Colmeia, Estado do Tocantins. Foram determinados 10 pontos de coleta (cinco para Cerrado nativo e cinco para pasto) para cada posição do relevo (topo, encosta e pedimento); em cada ponto amostral, foram coletados solos em três profundidades (0-5, 5-10 e 10- 15 cm), totalizando 90 amostras. Foram realizadas as seguintes análises químicas e físicas: C orgânico, P, K+, Ca2+, Mg2+, H + Al, pH e granulometria. O C orgânico não apresentou diferença (p > 0,05) entre os valores encontrados no Cerrado nativo e pastagem e as posições do relevo avaliadas. A conversão de Cerrado nativo para uso agropecuário reduziu os teores de P. Os teores de K trocável não foram alterados pela retirada da cobertura vegetal original. Observou-se aumento dos teores de areia quando se passou da meia-encosta para o pedimento.

Estoque de carbono e estabilidade de agregados de um latossolo vermelho distrófico, sob diferentes manejos

These systems of soil use and management are very important in carbon supply and stability of aggregates, because affect directly culture yields. The aim of this project is to evaluate the carbon supply and stability of Haplustox aggregates under different managements. It was utilized a completely randomized experimental design in split plot scheme, with six replications. Thus, the treatments utilized were three different soil managements ( native forest, pasture with Tanzania grass and corn). The plots were consisted by three layers (0-10; 10-20 and 20-30 cm) and were analyzed to determined the organic matter, organic carbon supply of soil ( layers and equivalent soil mass methods) and weighed average diameter (DMP) and geometrical average diameter (DMG). The results indicated that the evaluated managements systems affected the size of soil aggregates of the ground and in its distribution in the layer of 0-30 cm of depth. The greatest accumulation of carbon were in the surface layers, although, there were not variation between the management systems.
