En la ciudad he perdido una novela: la pérdida y el hallazgo (Dossier: Cuatro narradores del 30, relecturas en su centenario)

La autora reflexiona, a partir de esta novela de Humberto Salvador, sobre la razón de ser del texto novelesco. Resalta la intención del ecuatoriano de presentar una novela que busca integrar distintos discursos sociales, ensamblados como al azar, cuestionan diversas definiciones canónicas, tanto en lo literario como en lo social. Salvador prioriza en ellas el mostrar «cómo» se escribe una novela, y no el acabarla o dar por cerrado el producto. Concebido así, el texto novelesco se vuelve infinito, al igual que sus posibles lecturas: cada una produce una novela diferente, que jamás resulta definitiva.

Jorge Velasco Mackenzie: tatuaje de náufragos es la única novela en la que me he divertido escribiendo (De la Escena Contemporánea)

El autor entrevista al narrador guayaquileño Jorge Velasco Mackenzie, quien responde sobre su oficio de escritor. Velasco sostiene que sufre con sus personajes y agoniza cuando estos mueren. Mira a Tatuaje de náufragos como un homenaje a un bar generacional, a una época y una forma de ser artista que ya no existen más, sería la autopsia de una generación y de la ciudad. Velasco sostiene que el poeta Fernando Nieto no solo fue un animador de la bohemia del Montreal, el fundador de Sicoseo, sino un hombre que sabía mucho, y un hombre generoso en lo personal, admira la posición de Nieto frente al mundo, frente a la literatura. En los escritos de Velasco siempre está Guayaquil, porque es el lugar donde nació y es el único donde puede vivir. Podría decirse que escribir sobre Guayaquil es su proyecto estético. Considera al Montreal como un lugar vivo, abierto, con sus personajes y su rocola antigua, lo evocó así toda su vida y a lo largo del libro intentó devolverle ese esplendor.

Effects of short-term pH fluctuations on cadmium, nickel, lead, and zinc availability to ryegrass in a sewage sludge-amended field

In this field experiment, sewage sludge was applied at 0, 5, 10, and 50 t ha(-1), and the availability of Cd, Ni, Pb, and Zn was assessed both by ryegrass uptake and by DTPA extractions. The aim was to investigate the role of important soil parameters, particularly pH, on heavy metal availability. It was found that metal uptake and extractability increased significantly in the 50 t ha(-1) treatment. In the 16th week of the experiment there was a significant, although temporary, increase in DTPA-extractable Cd, Ni, and Zn concentrations. Metal concentrations in ryegrass were also significantly elevated in week 20 compared to the subsequent cuttings. These fluctuations in both DTPA and ryegrass uptake occurred only at 50 t ha(-1) and were probably induced by a sudden pH decrease measured in the same treatment in week 16. This suggests that soils which have received high applications of sewage sludge may be prone to fluctuations in metal availability. (c) 2007 Elsevier Ltd. All rights reserved.

Incorporating Legacy Soil pH Databases into Digital Soil Maps

Soil data and reliable soil maps are imperative for environmental management. conservation and policy. Data from historical point surveys, e.g. experiment site data and farmers fields can serve this purpose. However, legacy soil information is not necessarily collected for spatial analysis and mapping such that the data may not have immediately useful geo-references. Methods are required to utilise these historical soil databases so that we can produce quantitative maps of soil propel-ties to assess spatial and temporal trends but also to assess where future sampling is required. This paper discusses two such databases: the Representative Soil Sampling Scheme which has monitored the agricultural soil in England and Wales from 1969 to 2003 (between 400 and 900 bulked soil samples were taken annually from different agricultural fields); and the former State Chemistry Laboratory, Victoria, Australia where between 1973 and 1994 approximately 80,000 soil samples were submitted for analysis by farmers. Previous statistical analyses have been performed using administrative regions (with sharp boundaries) for both databases, which are largely unrelated to natural features. For a more detailed spatial analysis that call be linked to climate and terrain attributes, gradual variation of these soil properties should be described. Geostatistical techniques such as ordinary kriging are suited to this. This paper describes the format of the databases and initial approaches as to how they can be used for digital soil mapping. For this paper we have selected soil pH to illustrate the analyses for both databases.

The Representative Soil Sampling Scheme of England and Wales: the spatial variation of topsoil nutrient status and pH between 1971 and 2001

The Representative Soil Sampling Scheme (RSSS) has monitored the soil of agricultural land in England and Wales since 1969. Here we describe the first spatial analysis of the data from these surveys using geostatistics. Four years of data (1971, 1981, 1991 and 2001) were chosen to examine the nutrient (available K, Mg and P) and pH status of the soil. At each farm, four fields were sampled; however, for the earlier years, coordinates were available for the farm only and not for each field. The averaged data for each farm were used for spatial analysis and the variograms showed spatial structure even with the smaller sample size. These variograms provide a reasonable summary of the larger scale of variation identified from the data of the more intensively sampled National Soil Inventory. Maps of kriged predictions of K generally show larger values in the central and southeastern areas (above 200 mg L-1) and an increase in values in the west over time, whereas Mg is fairly stable over time. The kriged predictions of P show a decline over time, particularly in the east, and those of pH show an increase in the east over time. Disjunctive kriging was used to examine temporal changes in available P using probabilities less than given thresholds of this element. The RSSS was not designed for spatial analysis, but the results show that the data from these surveys are suitable for this purpose. The results of the spatial analysis, together with those of the statistical analyses, provide a comprehensive view of the RSSS database as a basis for monitoring the soil. These data should be taken into account when future national soil monitoring schemes are designed.
