En la última década, Barcelona se ha convertido en una importante receptora de población inmigrante. Según datos estadísticos, el 14, 62% de la población es inmigrante, de los cuales el 29, 5% son jóvenes (Idescat 2010). Muchos de estos han arribado siguiendo el típico proceso de reagrupamiento familiar. El siguiente trabajo tiene por objetivo presentar la experiencia de distintos jóvenes sobre el fenómeno migratorio que experimentaron durante su adolescencia/ primera juventud. Lleva el propósito de destacar la importancia de dicha vivencia en la conformación de su identidad social. Se intentará indagar tanto sobre el papel que jugaron los diferentes actores implicados en el proceso de acogida y los años subsiguientes: amigos, familiares, escuela, administraciones, etc., como sobre el uso del espacio público y el espacio virtual en tanto facilitadores/obstaculizadores de su constitución como ciudadanos autónomos

La presente disertación constituye un breve acercamiento a las poéticas del silencio, constitutivas de El color de lo blanco del poeta colombiano Álvaro Rodríguez Torres y de Sacra del poeta ecuatoriano Alexis Naranjo. Para la aproximación teórica a los textos poéticos, he aplicado ciertas categorías fundamentales de la hermenéutica de Paul Ricoeur. El aporte del pensador francés es interpretar los poemas como un escenario de convergencia entre los niveles semántico, morfosintáctico y fonológico. Así, tras un capítulo introductoria, donde marco la orientación teórica y metodológica de la tesis, he procedido a revisar cada texto de los libros. Dicho estudio lo realicé bajo la premisa de encontrar los distintos elementos compositivos que caracterizan –o caracterizarían- a una determinada poética del silencio. Como parte de las conclusiones preliminares y finales, he propuesto una clasificación de las poéticas del silencio: el despojamiento y la contención. Debo apuntar, además, que las imágenes míticas presentes en cada uno de los textos han sido estudiadas con el propósito de evitar cualquier tipo de digresiones.

El color de la razón y del pensamiento crítico en las Américas, ha requerido de búsquedas encaminadas a explicar el porqué del color y sus matices. La modernidad europea y latinoamericana, constituyen el escenario en donde hemos visualizado la actuación de imágenes conceptuales que enfatizan el “color” de cada actor y acción. Para el efecto, analizamos “ciertos” aspectos de las propuestas de algunos pensadores, en tres momentos: En el primero a Leopoldo Zea, quien enfatiza la articulación entre la dialéctica del colonialismo y la dependencia, mediada por la dialéctica hegeliana y marxista; y, a Bolívar Echeverría, en lo referente a la relación que se da en América Latina entre modernidad, capitalismo y mestizaje (barroco) o apartheid. En el segundo, la intersección mediada clase/raza manifiesta en las tesis de Aimé Césaire y Frantz Fanon. En el tercero, la “crítica negativa” del paradigma modernidad/colonialidad, elaborada por Aníbal Quijano, Enrique Dussel, Walter Mignolo y Nelson Maldonado, entre otros. La elaboración teórica y la re-construcción de los momentos históricos, simultáneamente concebidos, nos han permitido descifrar el “color” de la razón, como momento necesario para establecer las condiciones que posibilitan un diálogo filosófico intercultural.

El presente trabajo pretende contribuir en la ampliación de un corpus de estudio sobre la imagen del afrodescendiente. Se trata del análisis de la novela Jonatás y Manuela, de la afroecuatoriana Luz Argentina Chiriboga y del video Ecuatoriano Freddy Quiñones, detenido por cruzar con luz roja en Chile. En ambas narrativas se muestra la subyugación a la que son sometidos los cuerpos de los afrodescendientes. Con este propósito se procura rastrear cómo la percepción del color, asociada a las marcas étnicas y racistas heredadas de los discursos coloniales del siglo XVI al XVIII y los nacionalistas del XIX, se resemantiza en el siglo XX exponiendo las tensiones entre etnia/territorio/cultura a través de sujetos sociales que tradicionalmente han carecido de espacios de visibilidad para su propia representación, como agentes históricos y de acción política. Con esta intención, vale entonces emprender nuestro recorrido junto a las reflexiones de Hering, Cunin, Ariza, Chaves, Ramos, Montelongo, Miranda y Handelsman, quienes exploran las continuidades y discontinuidades que los diferentes discursos canónicos han sustentado alrededor de la percepción del color de piel en relación a la “raza” y a la identidad latinoamericana. Además, de manera simultánea, se analizarán los escenarios de subyugación desde la enunciación, los conceptos de utopía y heterotopía –de Michael Focuault-. De este modo, por razones de organización del corpus de estudio, tanto la novela como el video serán estudiados en cada uno de tres capítulos que componen el presente trabajo desde la configuración del color y del cuerpo en distintos escenarios: primero, el de subyugación que produce perspectivas indicadas.

We tested the hypothesis that cryptically colored eggs would suffer less predation than conspicuous eggs in the ground-nesting red-legged partridge, Alectoris rufa. We used A. rufa as a model species because it has a wide range of natural egg colors, the eggs are widely available from breeding farms, and nests are easily mimicked because they are scrapes containing no vegetation. The study was conducted in the spring of 2001 in forest and fallow fields of central Spain in Castilla La Mancha, Ciudad Real. We used 384 clutches of natural eggs that were white, white spotted, brown, or brown spotted. Within clutches, eggs were consistent in color and size; among clutches, color differences were distributed across habitats. Clutches were checked once after 2 wk of exposure. Cryptic coloration had a survival advantage that was dependent on the local suite of predators. Rodent predation was nonselective with respect to clutch color; however, avian predation was significantly higher for conspicuous clutches. In addition, there was an interaction of landscape and egg color for avian predation. In forest landscapes, the clutches with highest survival were brown spotted, whereas in fallow landscapes, brown and brown spotted clutches had higher survival than white and white potted clutches. Thus, both the predator suite and the landscape had significant effects on the value of cryptic egg coloration. Our study is relevant for conservationists and managers in charge of restocking programs in hunting areas. The release of other partridge species or their hybrids could result in hybridization with wild partridges, potentially leading to nonoptimal clutch pigmentation and reduced survival of the native species. We therefore recommend that local authorities, managers, and conservationists be cautious with the use of alien species and hybrids and release only autochthonous species of partridges within their natural ranges.

Chemical compositions and physical properties of mixed-sex Thai indigenous (Gallus domesticus) and broiler (commercial breed, CP707) chicken biceps femoris and pectoralis muscles were determined. Indigenous chicken muscles contained higher protein contents but lower fat and ash contents compared to broiler muscles (P < 0.001). The amino acid profile of the indigenous chicken muscles was similar to that of the broiler muscles except they were slightly richer in glutamic acid (P < 0.05). The indigenous chicken muscles contained more saturated and less polyunsaturated fatty acids than the broiler muscles. There were no differences in the monounsaturated fatty acid contents between the breeds. The total collagen contents of indigenous pectoralis and biceps femoris muscles were 5.09 and 12.85 mg/g, respectively, which were higher than those found in broiler pectoralis (3.86 mg/g) and biceps femoris muscles (8.70 mg/g) (P < 0.001). Soluble collagen contents were lower for indigenous pectoralis and biceps femoris muscles, 22.16 vs. 31.38% and 26.06 vs. 33.87%, respectively. The CIE system values of lightness (L*), redness (a*), and yellowness (b*) of indigenous chicken muscles were higher than those of broiler muscles. The shear values of indigenous chicken muscles either raw or cooked were higher than those of broiler muscles (P < 0.05). After cooking, the shear values decreased for broiler biceps femoris and pectoralis muscles (P < 0.05), whereas no change was observed for indigenous chicken biceps femoris muscle (P > 0.05). Shear values increased for indigenous chicken pectoralis muscle (P < 0.05).

Green malt was kilned at 95 degrees C following two regimens: a standard regimen (SKR) and a rapid regimen (RKR). Both resulting malts were treated further in a tray dryer heated to 120 degrees C, as was green malt previously dried to 65 degrees C (TDR). Each regimen was monitored by determining the color, antioxidant activity (by both ABTS(center dot+) and FRAP methods), and polyphenolic profile. SKR and RKR malts exhibited decreased L* and increased b* values above approximately 80 degrees C. TDR malts changed significantly less, and color did not develop until 110 degrees C, implying that different chemical reactions lead to color in those malts. Antioxidant activity increased progressively with each regimen, although with TDR malts this became significant only at 110-120 degrees C. The RKR malt ABTS(center dot+) values were higher than those of the SKR malt. The main phenolics, that is, ferulic, p-coumaric, and vanillic acids, were monitored throughout heating. Ferulic acid levels increased upon heating to 80 degrees C for SKR and to 70 degrees C for RKR, with subsequent decreases. However, the levels for TDR malts did not increase significantly. The increase in free phenolics early in kilning could be due to enzymatic release of bound phenolics and/or easier extractability due to changes in the matrix. The differences between the kilning regimens used suggest that further modification of the regimens could lead to greater release of bound phenolics with consequent beneficial effects on flavor stability in beer and, more generally, on human health.

Optical characteristics of stirred curd were simultaneously monitored during syneresis in a 10-L cheese vat using computer vision and colorimetric measurements. Curd syneresis kinetic conditions were varied using 2 levels of milk pH (6.0 and 6.5) and 2 agitation speeds (12.1 and 27.2 rpm). Measured optical parameters were compared with gravimetric measurements of syneresis, taken simultaneously. The results showed that computer vision and colorimeter measurements have potential for monitoring syneresis. The 2 different phases, curd and whey, were distinguished by means of color differences. As syneresis progressed, the backscattered light became increasingly yellow in hue for circa 20 min for the higher stirring speed and circa 30 min for the lower stirring speed. Syneresis-related gravimetric measurements of importance to cheese making (e.g., curd moisture content, total solids in whey, and yield of whey) correlated significantly with computer vision and colorimetric measurements..

Radical contextualists have observed that the content of what is said by the utterance of a sentence is shaped in far-reaching ways by the context of utterance. And they have argued that the ways in which the content of what is said is shaped by context cannot be explained by semantic theory. A striking number of the examples that radical contextualists use to support their view involve sentences containing color adjectives (“red”, “green”, etc.). In this paper, I show how the most sophisticated analysis of color adjectives within the explanatory framework of compositional truth conditional semantics—recently developed by Kennedy and McNally (Synthese 174(1):79–98 2010)—needs to be modified to handle the full range of contextual variation displayed by color adjectives.
